--- _id: '12291' abstract: - lang: eng text: The phytohormone auxin triggers transcriptional reprogramming through a well-characterized perception machinery in the nucleus. By contrast, mechanisms that underlie fast effects of auxin, such as the regulation of ion fluxes, rapid phosphorylation of proteins or auxin feedback on its transport, remain unclear1,2,3. Whether auxin-binding protein 1 (ABP1) is an auxin receptor has been a source of debate for decades1,4. Here we show that a fraction of Arabidopsis thaliana ABP1 is secreted and binds auxin specifically at an acidic pH that is typical of the apoplast. ABP1 and its plasma-membrane-localized partner, transmembrane kinase 1 (TMK1), are required for the auxin-induced ultrafast global phospho-response and for downstream processes that include the activation of H+-ATPase and accelerated cytoplasmic streaming. abp1 and tmk mutants cannot establish auxin-transporting channels and show defective auxin-induced vasculature formation and regeneration. An ABP1(M2X) variant that lacks the capacity to bind auxin is unable to complement these defects in abp1 mutants. These data indicate that ABP1 is the auxin receptor for TMK1-based cell-surface signalling, which mediates the global phospho-response and auxin canalization. acknowledged_ssus: - _id: Bio - _id: EM-Fac - _id: LifeSc acknowledgement: We acknowledge K.

Quantization is a technique that trades numerical precision for the computational efficiency of running a neural network and is widely adopted in industry.\r\nWe show that neglecting the reduced precision when verifying a neural network can lead to wrong conclusions about the robustness and safety of the network, highlighting that novel techniques for quantized network verification are necessary. We introduce several bit-exact verification methods explicitly designed for quantized neural networks and experimentally confirm on realistic networks that the network's robustness and other formal properties are affected by the quantization.\r\n\r\nFurthermore, we perform a case study providing evidence that adversarial training, a standard technique for making neural networks more robust, has detrimental effects on the network's performance. This robustness-accuracy tradeoff has been studied before regarding the accuracy obtained on classification datasets where each data point is independent of all other data points. On the other hand, we investigate the tradeoff empirically in robot learning settings where a both, a high accuracy and a high robustness, are desirable.\r\nOur results suggest that the negative side-effects of adversarial training outweigh its robustness benefits in practice.\r\n\r\nFinally, we consider the problem of verifying safety when running a Bayesian neural network policy in a feedback loop with systems over the infinite time horizon. Bayesian neural networks are probabilistic models for learning uncertainties in the data and are therefore often used on robotic and healthcare applications where data is inherently stochastic.\r\nWe introduce a method for recalibrating Bayesian neural networks so that they yield probability distributions over safe decisions only.\r\nOur method learns a safety certificate that guarantees safety over the infinite time horizon to determine which decisions are safe in every possible state of the system.\r\nWe demonstrate the effectiveness of our approach on a series of reinforcement learning benchmarks." alternative_title: - ISTA Thesis article_processing_charge: No author: - first_name: Mathias full_name: Lechner, Mathias id: 3DC22916-F248-11E8-B48F-1D18A9856A87 last_name: Lechner citation: ama: Lechner M.

It is a challenging problem to construct a protocol with similar security guarantees that can efficiently scale to large groups. A major bottleneck are the frequent key rotations users need to perform to achieve post compromise forward security.\r\n\r\nIn current proposals – most notably in TreeKEM (which is part of the IETF’s Messaging Layer Security (MLS) protocol draft) – for users in a group of size n to rotate their keys, they must each craft a message of size log(n) to be broadcast to the group using an (untrusted) delivery server.\r\n\r\nIn larger groups, having users sequentially rotate their keys requires too much bandwidth (or takes too long), so variants allowing any T≤n users to simultaneously rotate their keys in just 2 communication rounds have been suggested (e.g. “Propose and Commit” by MLS). Unfortunately, 2-round concurrent updates are either damaging or expensive (or both); i.e. they either result in future operations being more costly (e.g. via “blanking” or “tainting”) or are costly themselves requiring Ω(T) communication for each user [Bienstock et al., TCC’20].\r\n\r\nIn this paper we propose CoCoA; a new scheme that allows for T concurrent updates that are neither damaging nor costly. That is, they add no cost to future operations yet they only require Ω(log2(n)) communication per user. To circumvent the [Bienstock et al.] lower bound, CoCoA increases the number of rounds needed to complete all updates from 2 up to (at most) log(n); though typically fewer rounds are needed.\r\n\r\nThe key insight of our protocol is the following: in the (non-concurrent version of) TreeKEM, a delivery server which gets T concurrent update requests will approve one and reject the remaining T−1. In contrast, our server attempts to apply all of them. If more than one user requests to rotate the same key during a round, the server arbitrarily picks a winner. Surprisingly, we prove that regardless of how the server chooses the winners, all previously compromised users will recover after at most log(n) such update rounds.\r\n\r\nTo keep the communication complexity low, CoCoA is a server-aided CGKA. That is, the delivery server no longer blindly forwards packets, but instead actively computes individualized packets tailored to each user. As the server is untrusted, this change requires us to develop new mechanisms ensuring robustness of the protocol." acknowledgement: We thank Marta Mularczyk and Yiannis Tselekounis for their very helpful feedback on an earlier draft of this paper. alternative_title: - LNCS article_processing_charge: No author: - first_name: Joël full_name: Alwen, Joël last_name: Alwen - first_name: Benedikt full_name: Auerbach, Benedikt id: D33D2B18-E445-11E9-ABB7-15F4E5697425 last_name: Auerbach orcid: 0000-0002-7553-6606 - first_name: Miguel full_name: Cueto Noval, Miguel id: ffc563a3-f6e0-11ea-865d-e3cce03d17cc last_name: Cueto Noval orcid: 0000-0002-2505-4246 - first_name: Karen full_name: Klein, Karen id: 3E83A2F8-F248-11E8-B48F-1D18A9856A87 last_name: Klein - first_name: Guillermo full_name: Pascual Perez, Guillermo id: 2D7ABD02-F248-11E8-B48F-1D18A9856A87 last_name: Pascual Perez orcid: 0000-0001-8630-415X - first_name: Krzysztof Z full_name: Pietrzak, Krzysztof Z id: 3E04A7AA-F248-11E8-B48F-1D18A9856A87 last_name: Pietrzak orcid: 0000-0002-9139-1654 - first_name: Michael full_name: Walter, Michael last_name: Walter citation: ama: 'Alwen J, Auerbach B, Cueto Noval M, et al.

While synaptic transmission remains a dynamic process, electron microscopy provides images with comparably low temporal resolution (Studer et al., 2014). The current work overcomes this challenge and describes an improved “Flash and Freeze” technique (Watanabe et al., 2013a; Watanabe et al., 2013b) to study synaptic transmission at the hippocampal mossy fiber-CA3 pyramidal neuron synapses, using mouse acute brain slices and organotypic slices culture. The improved method allowed for selective stimulation of presynaptic mossy fiber boutons and the observation of synaptic vesicle pool dynamics at the active zones. Our results uncovered several intriguing morphological features of mossy fiber boutons. First, the docked vesicle pool was largely depleted (more than 70%) after stimulation, implying that the docked synaptic vesicles pool and readily releasable pool are vastly overlapping in mossy fiber boutons. Second, the synaptic vesicles are skewed towards larger diameters, displaying a wide range of sizes. An increase in the mean diameter of synaptic vesicles, after single and repetitive stimulation, suggests that smaller vesicles have a higher release probability. Third, we observed putative endocytotic structures after moderate light stimulation, matching the timing of previously described ultrafast endocytosis (Watanabe et al., 2013a; Delvendahl et al., 2016). \r\n\tIn addition, synaptic transmission depends on a sophisticated system of protein machinery and calcium channels (Südhof, 2013b), which amplifies the challenge in studying synaptic communication as these interactions can be potentially modified during synaptic plasticity. And although recent study elucidated the potential correlation between physiological and morphological properties of synapses during synaptic plasticity (Vandael et al., 2020), the molecular underpinning of it remains unknown. Thus, the presented work tries to overcome this challenge and aims to pinpoint changes in the molecular architecture at hippocampal mossy fiber bouton synapses during short- and long-term potentiation (STP and LTP), we combined chemical potentiation, with the application of a cyclic adenosine monophosphate agonist (i.e. forskolin) and freeze-fracture replica immunolabelling. This method allowed the localization of membrane-bound proteins with nanometer precision within the active zone, in particular, P/Q-type calcium channels and synaptic vesicle priming proteins Munc13-1/2. First, we found that the number of clusters of Munc13-1 in the mossy fiber bouton active zone increased significantly during STP, but decreased to lower than the control value during LTP. Secondly, although the distance between the calcium channels and Munc13-1s did not change after induction of STP, it shortened during the LTP phase. Additionally, forskolin did not affect Munc13-2 distribution during STP and LTP. These results indicate the existence of two distinct mechanisms that govern STP and LTP at mossy fiber bouton synapses: an increase in the readily realizable pool in the case of STP and a potential increase in release probability during LTP. “Flash and freeze” and functional electron microscopy, are versatile methods that can be successfully applied to intact brain circuits to study synaptic transmission even at the molecular level.\r\n" acknowledged_ssus: - _id: EM-Fac - _id: PreCl alternative_title: - ISTA Thesis article_processing_charge: No author: - first_name: Olena full_name: Kim, Olena id: 3F8ABDDA-F248-11E8-B48F-1D18A9856A87 last_name: Kim orcid: 0000-0003-2344-1039 citation: ama: Kim O.

Plants are\r\nsessile organisms, thus to compensate for their lack of mobility, they evolved a variety of\r\nmechanisms enabling them to flexibly adjust their physiological, growth and developmental\r\nprocesses to fluctuating temperatures and to survive in harsh environments. While these unique\r\nadaptation abilities provide an important evolutionary advantage, overall modulation of plant\r\ngrowth and developmental program due to non-optimal temperature negatively affects biomass\r\nproduction, crop productivity or sensitivity to pathogens. Thus, understanding molecular\r\nprocesses underlying plant adaptation to increased temperature can provide important\r\nresources for breeding strategies to ensure sufficient agricultural food production.\r\nAn increase in ambient temperature by a few degrees leads to profound changes in organ growth\r\nincluding enhanced hypocotyl elongation, expansion of petioles, hyponastic growth of leaves and\r\ncotyledons, collectively named thermomorphogenesis (Casal & Balasubramanian, 2019). Auxin,\r\none of the best-studied growth hormones, plays an essential role in this process by direct\r\nactivation of transcriptional and non-transcriptional processes resulting in elongation growth\r\n(Majda & Robert, 2018).To modulate hypocotyl growth in response to high ambient temperature\r\n(hAT), auxin needs to be redistributed accordingly. PINs, auxin efflux transporters, are key\r\ncomponents of the polar auxin transport (PAT) machinery, which controls the amount and\r\ndirection of auxin translocated in the plant tissues and organs(Adamowski & Friml, 2015). Hence,\r\nPIN-mediated transport is tightly linked with thermo-morphogenesis, and interference with PAT\r\nthrough either chemical or genetic means dramatically affecting the adaptive responses to hAT.\r\nIntriguingly, despite the key role of PIN mediated transport in growth response to hAT, whether\r\nand how PINs at the level of expression adapt to fluctuation in temperature is scarcely\r\nunderstood.\r\nWith genetic, molecular and advanced bio-imaging approaches, we demonstrate the role of PIN\r\nauxin transporters in the regulation of hypocotyl growth in response to hAT. We show that via\r\nadjustment of PIN3, PIN4 and PIN7 expression in cotyledons and hypocotyls, auxin distribution is modulated thereby determining elongation pattern of epidermal cells at hAT. Furthermore, we\r\nidentified three Zinc-Finger (ZF) transcription factors as novel molecular components of the\r\nthermo-regulatory network, which through negative regulation of PIN transcription adjust the\r\ntransport of auxin at hAT. Our results suggest that the ZF-PIN module might be a part of the\r\nnegative feedback loop attenuating the activity of the thermo-sensing pathway to restrain\r\nexaggerated growth and developmental responses to hAT." acknowledged_ssus: - _id: Bio - _id: LifeSc - _id: SSU acknowledgement: I would like to acknowledge ISTA and all the people from the Scientific Service Units and at ISTA, in particular Dorota Jaworska for excellent technical and scientific support as well as ÖAW for funding my research for over 3 years (DOC ÖAW Fellowship PR1022OEAW02). alternative_title: - ISTA Thesis article_processing_charge: No author: - first_name: Christina full_name: Artner, Christina id: 45DF286A-F248-11E8-B48F-1D18A9856A87 last_name: Artner citation: ama: Artner C.

These disorders show a high degree\r\nof heritability and hundreds of risk genes have been identifed using high throughput\r\nsequencing technologies. This genetic heterogeneity has hampered eforts in understanding\r\nthe pathogenesis of ASD but at the same time given rise to the concept of convergent\r\nmechanisms. Previous studies have identifed that risk genes for ASD broadly converge\r\nonto specifc functional categories with transcriptional regulation being one of the biggest\r\ngroups. In this thesis, I focus on this subgroup of genes and investigate the gene regulatory\r\nconsequences of some of them in the context of neurodevelopment.\r\nFirst, we showed that mutations in the ASD and intellectual disability risk gene Setd5 lead\r\nto perturbations of gene regulatory programs in early cell fate specifcation. In addition,\r\nadult animals display abnormal learning behavior which is mirrored at the transcriptional\r\nlevel by altered activity dependent regulation of postsynaptic gene expression. Lastly,\r\nwe link the regulatory function of Setd5 to its interaction with the Paf1 and the NCoR\r\ncomplex.\r\nSecond, by modeling the heterozygous loss of the top ASD gene CHD8 in human cerebral\r\norganoids we demonstrate profound changes in the developmental trajectories of both\r\ninhibitory and excitatory neurons using single cell RNA-sequencing. While the former\r\nwere generated earlier in CHD8+/- organoids, the generation of the latter was shifted to\r\nlater times in favor of a prolonged progenitor expansion phase and ultimately increased\r\norganoid size.\r\nFinally, by modeling heterozygous mutations for four ASD associated chromatin modifers,\r\nASH1L, KDM6B, KMT5B, and SETD5 in human cortical spheroids we show evidence of\r\nregulatory convergence across three of those genes. We observe a shift from dorsal cortical\r\nexcitatory neuron fates towards partially ventralized cell types resembling cells from the\r\nlateral ganglionic eminence. As this project is still ongoing at the time of writing, future\r\nexperiments will aim at elucidating the regulatory mechanisms underlying this shift with\r\nthe aim of linking these three ASD risk genes through biological convergence." alternative_title: - ISTA Thesis article_processing_charge: No author: - first_name: Christoph full_name: Dotter, Christoph id: 4C66542E-F248-11E8-B48F-1D18A9856A87 last_name: Dotter orcid: 0000-0002-9033-9096 citation: ama: Dotter C.

These receptors are composed of different subunits and the subunit composition can\r\naffect channel properties, receptor trafficking and interaction with other associated proteins.\r\nUsing the high sensitivity SDS-digested freeze-fracture replica labeling (SDS-FRL) for\r\nelectron microscopy I investigated the number, density, and localization of AMPAR subunits,\r\nGluA1, GluA2, GluA3, and GluA1-3 (panAMPA) in pyramidal cells in the CA1 area of mouse\r\nhippocampus. I have found that the immunogold labeling for all of these subunits in the\r\npostsynaptic sites was highest in stratum radiatum and lowest in stratum lacunosummoleculare. The labeling density for the all subunits in the extrasynaptic sites showed a gradual\r\nincrease from the pyramidal cell soma towards the distal part of stratum radiatum. The densities\r\nof extrasynaptic GluA1, GluA2 and panAMPA labeling reached 10-15% of synaptic densities,\r\nwhile the ratio of extrasynaptic labeling for GluA3 was significantly lower compared than those\r\nfor other subunits. The labeling patterns for GluA1, GluA2 and GluA1-3 are similar and their\r\ndensities were higher in the periphery than center of synapses. In contrast, the GluA3-\r\ncontaining receptors were more centrally localized compared to the GluA1- and GluA2-\r\ncontaining receptors.\r\nThe hippocampus plays a central role in learning and memory. Contextual learning has been\r\nshown to require the delivery of AMPA receptors to CA1 synapses in the dorsal hippocampus.\r\nHowever, proximodistal heterogeneity of this plasticity and particular contribution of different\r\nAMPA receptor subunits are not fully understood. By combining inhibitory avoidance task, a\r\nhippocampus-dependent contextual fear-learning paradigm, with SDS-FRL, I have revealed an\r\nincrease in synaptic density specific to GluA1-containing AMPA receptors in the CA1 area.\r\nThe intrasynaptic distribution of GluA1 also changed from the periphery to center-preferred\r\npattern. Furthermore, this synaptic plasticity was evident selectively in stratum radiatum but\r\nnot stratum oriens, and in the CA1 subregion proximal but not distal to CA2. These findings\r\nfurther contribute to our understanding of how specific hippocampal subregions and AMPA\r\nreceptor subunits are involved in physiological learning.\r\nAlthough the immunolabeling results above shed light on subunit-specific plasticity in\r\nAMPAR distribution, no tools to visualize and study the subunit composition at the single\r\nchannel level in situ have been available. Electron microscopy with conventional immunogold\r\nlabeling approaches has limitations in the single channel analysis because of the large size of\r\nantibodies and steric hindrance hampering multiple subunit labeling of single channels. I\r\nmanaged to develop a new chemical labeling system using a short peptide tag and small\r\nsynthetic probes, which form specific covalent bond with a cysteine residue in the tag fused to\r\nproteins of interest (reactive tag system).

In contrast to classical\r\ncomputers based on bits that are represented by a single binary value, 0 or 1, quantum\r\nbits (or qubits) can be in a superposition of both. Thus, quantum computers can store\r\nand handle more information at the same time and a quantum advantage has already\r\nbeen demonstrated for two types of computational tasks. Rapid progress in academic\r\nand industry labs accelerates the development of superconducting processors which may\r\nsoon fnd applications in complex computations, chemical simulations, cryptography, and\r\noptimization. Now that these machines are scaled up to tackle such problems the questions\r\nof qubit interconnects and networks becomes very relevant. How to route signals on-chip\r\nbetween diferent processor components? What is the most efcient way to entangle\r\nqubits? And how to then send and process entangled signals between distant cryostats\r\nhosting superconducting processors?\r\nIn this thesis, we are looking for solutions to these problems by studying the collective\r\nbehavior of superconducting qubit ensembles. We frst demonstrate on-demand tunable\r\ndirectional scattering of microwave photons from a pair of qubits in a waveguide. Such a\r\ndevice can route microwave photons on-chip with a high diode efciency. Then we focus\r\non studying ultra-strong coupling regimes between light (microwave photons) and matter\r\n(superconducting qubits), a regime that could be promising for extremely fast multi-qubit\r\nentanglement generation. Finally, we show coherent pulse storage and periodic revivals\r\nin a fve qubit ensemble strongly coupled to a resonator. Such a reconfgurable storage\r\ndevice could be used as part of a quantum repeater that is needed for longer-distance\r\nquantum communication.\r\nThe achieved high degree of control over multi-qubit ensembles highlights not only the\r\nbeautiful physics of circuit quantum electrodynamics, it also represents the frst step\r\ntoward new quantum simulation and communication methods, and certain techniques\r\nmay also fnd applications in future superconducting quantum computing hardware.\r\n" acknowledged_ssus: - _id: NanoFab - _id: M-Shop - _id: EM-Fac alternative_title: - ISTA Thesis article_processing_charge: No author: - first_name: Elena full_name: Redchenko, Elena id: 2C21D6E8-F248-11E8-B48F-1D18A9856A87 last_name: Redchenko citation: ama: Redchenko E.

FtsA allegedly initiates cell division by switching from an inactive polymeric to an active monomeric confirmation, which recruits downstream proteins and stabilizes FtsZ filaments. Here, we use biochemical reconstitution experiments combined with quantitative fluorescence microscopy to study divisome activation in vitro. We compare wildtype-FtsA with FtsA-R286W, a constantly active gain-of-function mutant and find that R286W outperforms the wildtype protein in replicating FtsZ treadmilling dynamics, stabilizing FtsZ filaments and recruiting FtsN. We attribute these differences to a faster membrane exchange of FtsA-R286W and its higher packing density below FtsZ filaments. Using FRET microscopy, we find that FtsN binding does not compete with, but promotes FtsA self-interaction. Our findings suggest a model where FtsA always forms dynamic polymers on the membrane, which re-organize during assembly and activation of the divisome.

However, the mechanisms immune\r\ncells utilize to collectively migrate through tissue barriers in vivo are not yet well understood.\r\nIn this thesis, I describe two mechanisms that Drosophila immune cells (hemocytes) use to\r\novercome the tissue barrier of the germband in the embryo. One strategy is the strengthening\r\nof the actin cortex through developmentally controlled transcriptional regulation induced by\r\nthe Drosophila proto-oncogene family member Dfos, which I show in Chapter 2. Dfos induces\r\nexpression of the tetraspanin TM4SF and the filamin Cher leading to higher levels of the\r\nactivated formin Dia at the cortex and increased cortical F-actin. This enhanced cortical\r\nstrength allows hemocytes to overcome the physical resistance of the surrounding tissue and\r\ntranslocate their nucleus to move forward. This mechanism affects the speed of migration\r\nwhen hemocytes face a confined environment in vivo.\r\nAnother aspect of the invasion process is the initial step of the leading hemocytes entering\r\nthe tissue, which potentially guides the follower cells. In Chapter 3, I describe a novel\r\nsubpopulation of hemocytes activated by BMP signaling prior to tissue invasion that leads\r\npenetration into the germband. Hemocytes that are deficient in BMP signaling activation\r\nshow impaired persistence at the tissue entry, while their migration speed remains\r\nunaffected.\r\nThis suggests that there might be different mechanisms controlling immune cell migration\r\nwithin the confined environment in vivo, one of these being the general ability to overcome\r\nthe resistance of the surrounding tissue and another affecting the order of hemocytes that\r\ncollectively invade the tissue in a stream of individual cells.\r\nTogether, my findings provide deeper insights into transcriptional changes in immune\r\ncells that enable efficient tissue invasion and pave the way for future studies investigating the\r\nearly colonization of tissues by macrophages in higher organisms. Moreover, they extend the\r\ncurrent view of Drosophila immune cell heterogeneity and point toward a potentially\r\nconserved role for canonical BMP signaling in specifying immune cells that lead the migration\r\nof tissue resident macrophages during embryogenesis." acknowledged_ssus: - _id: LifeSc alternative_title: - ISTA Thesis article_processing_charge: No author: - first_name: Stephanie full_name: Wachner, Stephanie id: 2A95E7B0-F248-11E8-B48F-1D18A9856A87 last_name: Wachner citation: ama: Wachner S.

Strategies to \r\ncharacterize these changes usually involve user-selected morphometric features, which \r\npreclude the identification of a spectrum of context-dependent morphological phenotypes. \r\nHere, we develop MorphOMICs, a topological data analysis approach, which enables semi\x02automatic mapping of microglial morphology into an atlas of cue-dependent phenotypes,\r\novercomes feature-selection bias and minimizes biological variability. \r\nFirst, with MorphOMICs we derive the morphological spectrum of microglia across seven \r\nbrain regions during postnatal development and in two distinct Alzheimer’s disease \r\ndegeneration mouse models. We uncover region-specific and sexually dimorphic\r\nmorphological trajectories, with females showing an earlier morphological shift than males in \r\nthe degenerating brain. Overall, we demonstrate that both long primary- and short terminal \r\nprocesses provide distinct insights to morphological phenotypes. Moreover, using machine \r\nlearning to map novel condition on the spectrum, we observe that microglia morphologies \r\nreflect a dose-dependent adaptation upon ketamine anesthesia and do not recover to control \r\nmorphologies.\r\nNext, we took advantage of MorphOMICs to build a high-resolution and layer-specific map of \r\nmicroglial morphological spectrum in the retina, covering postnatal development and rd10 \r\ndegeneration. Here, following photoreceptor death, microglia assume an early development\x02like morphology. Finally, we map microglial morphology following optic nerve crush on the \r\nretinal spectrum and observe a layer- and sex-dependent response. \r\nOverall, MorphOMICs opens a new perspective to analyze microglial morphology across \r\nmultiple conditions, and provides a novel tool to characterize microglial morphology beyond \r\nthe traditionally dichotomized view of microglia." acknowledged_ssus: - _id: PreCl - _id: Bio - _id: ScienComp alternative_title: - ISTA Thesis article_processing_charge: No author: - first_name: Gloria full_name: Colombo, Gloria id: 3483CF6C-F248-11E8-B48F-1D18A9856A87 last_name: Colombo orcid: 0000-0001-9434-8902 citation: ama: Colombo G.

It is unclear, which factors contribute to this step.\r\nRecent studies indicate a crucial role of the tumor microenvironment in malignant\r\ntransformation and metastasis. Studying cancer cell invasion and detachments quantitatively in\r\nthe context of its physiological microenvironment is technically challenging. Especially, precise\r\ncontrol of microenvironmental properties in vivo is currently not possible. Here, I studied the\r\nrole of microenvironment geometry in the invasion and detachment of cancer cells from the\r\nbulk with a simplistic and reductionist approach. In this approach, I engineered microfluidic\r\ndevices to mimic a pseudo 3D extracellular matrix environment, where I was able to\r\nquantitatively tune the geometrical configuration of the microenvironment and follow tumor\r\ncells with fluorescence live imaging. To aid quantitative analysis I developed a widely applicable\r\nsoftware application to automatically analyze and visualize particle tracking data.\r\nQuantitative analysis of tumor cell invasion in isotropic and anisotropic microenvironments\r\nshowed that heterogeneity in the microenvironment promotes faster invasion and more\r\nfrequent detachment of cells. These observations correlated with overall higher speed of cells at\r\nthe edge of the bulk of the cells. In heterogeneous microenvironments cells preferentially\r\npassed through larger pores, thus invading areas of least resistance and generating finger-like\r\ninvasive structures. The detachments occurred mostly at the tips of these structures.\r\nTo investigate the potential mechanism, we established a two dimensional model to simulate\r\nactive Brownian particles representing the cell nuclei dynamics. These simulations backed our in\r\nvitro observations without the need of precise fitting the simulation parameters. Our model\r\nsuggests the importance of the pore heterogeneity in the direction perpendicular to the\r\norientation of bias field (lateral heterogeneity), which causes the interface roughening." alternative_title: - ISTA Thesis article_processing_charge: No author: - first_name: Saren full_name: Tasciyan, Saren id: 4323B49C-F248-11E8-B48F-1D18A9856A87 last_name: Tasciyan orcid: 0000-0003-1671-393X citation: ama: Tasciyan S.

Although they are known to have ZW chromosomes, these are not well characterized, and it is unclear whether they are shared across the clade. Furthermore, the underlying genetic architecture of the transmission of asexuality, which can occur when rare males mate with closely related sexual females, is not well understood. We produced a chromosome-level assembly for the sexual Eurasian species A. sinica and characterized in detail the pair of sex chromosomes of this species. We combined this new assembly with short-read genomic data for the sexual species A. sp. Kazakhstan and several asexual lineages of A. parthenogenetica, allowing us to perform an in-depth characterization of sex-chromosome evolution across the genus. We identified a small differentiated region of the ZW pair that is shared by all sexual and asexual lineages, supporting the shared ancestry of the sex chromosomes. We also inferred that recombination suppression has spread to larger sections of the chromosome independently in the American and Eurasian lineages. Finally, we took advantage of a rare male, which we backcrossed to sexual females, to explore the genetic basis of asexuality. Our results suggest that parthenogenesis is likely partly controlled by a locus on the Z chromosome, highlighting the interplay between sex determination and asexuality. article_processing_charge: No author: - first_name: Marwan N full_name: Elkrewi, Marwan N id: 0B46FACA-A8E1-11E9-9BD3-79D1E5697425 last_name: Elkrewi orcid: 0000-0002-5328-7231 citation: ama: Elkrewi MN.

In mammals, the hippocampus\r\nis a brain region essential to the acquisition and consolidation of new memories. It is also\r\ninvolved in keeping track of one’s position in space and aids navigation. Although this\r\nspace-memory has been a source of contradiction, evidence supports the view that the role of\r\nthe hippocampus in navigation is memory, thanks to the formation of cognitive maps. First\r\nintroduced by Tolman in 1948, cognitive maps are generally used to organize experiences in\r\nmemory; however, the detailed mechanisms by which these maps are formed and stored are not\r\nyet agreed upon. Some influential theories describe this process as involving three fundamental\r\nsteps: initial encoding by the hippocampus, interactions between the hippocampus and other\r\ncortical areas, and long-term extra-hippocampal consolidation. In this thesis, I will show how\r\nthe investigation of cognitive maps of space helped to shed light on each of these three memory\r\nprocesses.\r\nThe first study included in this thesis deals with the initial encoding of spatial memories in\r\nthe hippocampus. Much is known about encoding at the level of single cells, but less about\r\ntheir co-activity or joint contribution to the encoding of novel spatial information. I will\r\ndescribe the structure of an interaction network that allows for efficient encoding of noisy\r\nspatial information during the first exploration of a novel environment.\r\nThe second study describes the interactions between the hippocampus and the prefrontal\r\ncortex (PFC), two areas directly and indirectly connected. It is known that the PFC, in concert\r\nwith the hippocampus, is involved in various processes, including memory storage and spatial\r\nnavigation. Nonetheless, the detailed mechanisms by which PFC receives information from the\r\nhippocampus are not clear. I will show how a transient improvement in theta phase locking of\r\nPFC cells enables interactions of cell pairs across the two regions.\r\nThe third study describes the learning of behaviorally-relevant spatial locations in the hippocampus and the medial entorhinal cortex. I will show how the accumulation of firing around\r\ngoal locations, a correlate of learning, can shed light on the transition from short- to long-term\r\nspatial memories and the speed of consolidation in different brain areas.\r\nThe studies included in this thesis represent the main scientific contributions of my Ph.D. They\r\ninvolve statistical analyses and models of neural responses of cells in different brain areas of\r\nrats executing spatial tasks. I will conclude the thesis by discussing the impact of the findings\r\non principles of memory formation and retention, including the mechanisms, the speed, and\r\nthe duration of these processes." acknowledgement: I acknowledge the support from the European Union’s Horizon 2020 research and innovation program under the Marie Skłodowska-Curie Grant Agreement No. 665385. alternative_title: - ISTA Thesis article_processing_charge: No author: - first_name: Michele full_name: Nardin, Michele id: 30BD0376-F248-11E8-B48F-1D18A9856A87 last_name: Nardin orcid: 0000-0001-8849-6570 citation: ama: Nardin M.

Even though pathogens should thrive in social insect colonies as the hosts engage in frequent social interactions, are closely related and live in a pathogen-rich environment, disease outbreaks are rare. This is because social insects have evolved mechanisms to keep pathogens at bay – and fight disease as a collective. Social insect colonies are often viewed as “superorganisms” with division of labor between reproductive “germ-like” queens and males and “somatic” workers, which together form an interdependent reproductive unit that parallels a multicellular body. Superorganisms possess a “social immune system” that comprises of collective disease defenses performed by the workers - summarized as “social immunity”. In social groups immunization (reduced susceptibility to a parasite upon secondary exposure to the same parasite) can e.g. be triggered by social interactions (“social immunization”). Social immunization can be caused by (i) asymptomatic low-level infections that are acquired during caregiving to a contagious individual that can give an immune boost, which can induce protection upon later encounter with the same pathogen (active immunization) or (ii) by transfer of immune effectors between individuals (passive immunization).\r\nIn the second chapter, I built up on a study that I co-authored that found that low-level infections can not only be protective, but also be costly and make the host more susceptible to detrimental superinfections after contact to a very dissimilar pathogen. I here now tested different degrees of phylogenetically-distant fungal strains of M. brunneum and M. robertsii in L. neglectus and can describe the occurrence of cross-protection of social immunization if the first and second pathogen are from the same level. Interestingly, low-level infections only provided protection when the first strain was less virulent than the second strain and elicited higher immune gene expression.\r\nIn the third and fourth chapters, I expanded on the role of social immunity in sexual selection, a so far unstudied field. I used the fungus Metarhizium robertsii and the ant Cardiocondyla obscurior as a model, as in this species mating occurs in the presence of workers and can be studied under laboratory conditions. Before males mate with virgin queens in the nest they engage in fierce combat over the access to their mating partners.\r\nFirst, I focused on male-male competition in the third chapter and found that fighting with a contagious male is costly as it can lead to contamination of the rival, but that workers can decrease the risk of disease contraction by performing sanitary care.\r\nIn the fourth chapter, I studied the effect of fungal infection on survival and mating success of sexuals (freshly emerged queens and males) and found that worker-performed sanitary care can buffer the negative effect that a pathogenic contagion would have on sexuals by spore removal from the exposed individuals. When social immunity was prevented and queens could contract spores from their mating partner, very low dosages led to negative consequences: their lifespan was reduced and they produced fewer offspring with poor immunocompetence compared to healthy queens. Interestingly, cohabitation with a late-stage infected male where no spore transfer was possible had a positive effect on offspring immunity – male offspring of mothers that apparently perceived an infected partner in their vicinity reacted more sensitively to fungal challenge than male offspring without paternal pathogen history." acknowledged_ssus: - _id: LifeSc alternative_title: - ISTA Thesis article_processing_charge: No author: - first_name: Sina full_name: Metzler, Sina id: 48204546-F248-11E8-B48F-1D18A9856A87 last_name: Metzler orcid: 0000-0002-9547-2494 citation: ama: Metzler S.

Recent work has investigated the even harder case of sparse training, where the DNN weights are, for as much as possible, already sparse to reduce computational costs during training. Existing sparse training methods are often empirical and can have lower accuracy relative to the dense baseline. In this paper, we present a general approach called Alternating Compressed/DeCompressed (AC/DC) training of DNNs, demonstrate convergence for a variant of the algorithm, and show that AC/DC outperforms existing sparse training methods in accuracy at similar computational budgets; at high sparsity levels, AC/DC even outperforms existing methods that rely on accurate pre-trained dense models. An important property of AC/DC is that it allows co-training of dense and sparse models, yielding accurate sparse–dense model pairs at the end of the training process. This is useful in practice, where compressed variants may be desirable for deployment in resource-constrained settings without re-doing the entire training flow, and also provides us with insights into the accuracy gap between dense and compressed models.

The specific examples being treated are two-phase Navier-Stokes flow with surface tension, modeling the evolution of two incompressible, viscous and immiscible fluids separated by a sharp interface, and multiphase mean curvature flow, which serves as an idealized model for the motion of grain boundaries in an annealing polycrystalline material. Our main results - obtained in joint works with Julian Fischer, Tim Laux and Theresa M. Simon - state that prior to the formation of geometric singularities due to topology changes, the weak solution concept of Abels (Interfaces Free Bound. 9, 2007) to two-phase Navier-Stokes flow with surface tension and the weak solution concept of Laux and Otto (Calc. Var. Partial Differential Equations 55, 2016) to multiphase mean curvature flow (for networks in R^2 or double bubbles in R^3) represents the unique solution to these interface evolution problems within the class of classical solutions, respectively. To the best of the author's knowledge, for interface evolution problems not admitting a geometric comparison principle the derivation of a weak-strong uniqueness principle represented an open problem, so that the works contained in the present thesis constitute the first positive results in this direction. The key ingredient of our approach consists of the introduction of a novel concept of relative entropies for a class of curvature driven interface evolution problems, for which the associated energy contains an interfacial contribution being proportional to the surface area of the evolving (network of) interface(s). The interfacial part of the relative entropy gives sufficient control on the interface error between a weak and a classical solution, and its time evolution can be computed, at least in principle, for any energy dissipating weak solution concept. A resulting stability estimate for the relative entropy essentially entails the above mentioned weak-strong uniqueness principles. The present thesis contains a detailed introduction to our relative entropy approach, which in particular highlights potential applications to other problems in curvature driven interface evolution not treated in this thesis. alternative_title: - ISTA Thesis article_processing_charge: No author: - first_name: Sebastian full_name: Hensel, Sebastian id: 4D23B7DA-F248-11E8-B48F-1D18A9856A87 last_name: Hensel orcid: 0000-0001-7252-8072 citation: ama: 'Hensel S.

More in detail, my research focuses on the study of transport costs on graphs, in particular the convergence and the stability of such problems in the discrete-to-continuum limit. This thesis also includes some results concerning\r\nnon-commutative optimal transport. The first chapter of this thesis consists of a general introduction to the optimal transport problems, both in the discrete, the continuous, and the non-commutative setting. Chapters 2 and 3 present the content of two works, obtained in collaboration with Peter Gladbach, Eva Kopfer, and Jan Maas, where we have been able to show the convergence of discrete transport costs on periodic graphs to suitable continuous ones, which can be described by means of a homogenisation result. We first focus on the particular case of quadratic costs on the real line and then extending the result to more general costs in arbitrary dimension. Our results are the first complete characterisation of limits of transport costs on periodic graphs in arbitrary dimension which do not rely on any additional symmetry. In Chapter 4 we turn our attention to one of the intriguing connection between evolution equations and optimal transport, represented by the theory of gradient flows. We show that discrete gradient flow structures associated to a finite volume approximation of a certain class of diffusive equations (Fokker–Planck) is stable in the limit of vanishing meshes, reproving the convergence of the scheme via the method of evolutionary Γ-convergence and exploiting a more variational point of view on the problem. This is based on a collaboration with Dominik Forkert and Jan Maas. Chapter 5 represents a change of perspective, moving away from the discrete world and reaching the non-commutative one. As in the discrete case, we discuss how classical tools coming from the commutative optimal transport can be translated into the setting of density matrices. In particular, in this final chapter we present a non-commutative version of the Schrödinger problem (or entropic regularised optimal transport problem) and discuss existence and characterisation of minimisers, a duality result, and present a non-commutative version of the well-known Sinkhorn algorithm to compute the above mentioned optimisers. This is based on a joint work with Dario Feliciangeli and Augusto Gerolin. Finally, Appendix A and B contain some additional material and discussions, with particular attention to Harnack inequalities and the regularity of flows on discrete spaces." acknowledged_ssus: - _id: M-Shop - _id: NanoFab acknowledgement: The author gratefully acknowledges support by the Austrian Science Fund (FWF), grants No W1245. alternative_title: - ISTA Thesis article_processing_charge: No author: - first_name: Lorenzo full_name: Portinale, Lorenzo id: 30AD2CBC-F248-11E8-B48F-1D18A9856A87 last_name: Portinale citation: ama: Portinale L.

For an execution of n events over k threads and d variables, we establish novel bounds that scale as nk+1 for TSO and as nk+1· min(nk2, 2k· d) for PSO. Moreover, based on our solution to these problems, we develop an SMC algorithm under TSO and PSO that uses the RF equivalence. The algorithm is exploration-optimal, in the sense that it is guaranteed to explore each class of the RF partitioning exactly once, and spends polynomial time per class when k is bounded. Finally, we implement all our algorithms in the SMC tool Nidhugg, and perform a large number of experiments over benchmarks from existing literature. Our experimental results show that our algorithms for VTSO-rf and VPSO-rf provide significant scalability improvements over standard alternatives. Moreover, when used for SMC, the RF partitioning is often much coarser than the standard Shasha-Snir partitioning for TSO/PSO, which yields a significant speedup in the model checking task.\r\n\r\n" acknowledgement: "The research was partially funded by the ERC CoG 863818 (ForM-SMArt) and the Vienna Science\r\nand Technology Fund (WWTF) through project ICT15-003." article_number: '164' article_processing_charge: No article_type: original arxiv: 1 author: - first_name: Truc Lam full_name: Bui, Truc Lam last_name: Bui - first_name: Krishnendu full_name: Chatterjee, Krishnendu id: 2E5DCA20-F248-11E8-B48F-1D18A9856A87 last_name: Chatterjee orcid: 0000-0002-4561-241X - first_name: Tushar full_name: Gautam, Tushar last_name: Gautam - first_name: Andreas full_name: Pavlogiannis, Andreas id: 49704004-F248-11E8-B48F-1D18A9856A87 last_name: Pavlogiannis orcid: 0000-0002-8943-0722 - first_name: Viktor full_name: Toman, Viktor id: 3AF3DA7C-F248-11E8-B48F-1D18A9856A87 last_name: Toman orcid: 0000-0001-9036-063X citation: ama: Bui TL, Chatterjee K, Gautam T, Pavlogiannis A, Toman V.
