--- _id: '12233' abstract: - lang: eng text: A novel recursive list decoding (RLD) algorithm for Reed-Muller (RM) codes based on successive permutations (SP) of the codeword is presented. A low-complexity SP scheme applied to a subset of the symmetry group of RM codes is first proposed to carefully select a good codeword permutation on the fly. Then, the proposed SP technique is integrated into an improved RLD algorithm that initializes different decoding paths with random codeword permutations, which are sampled from the full symmetry group of RM codes. Finally, efficient latency and complexity reduction schemes are introduced that virtually preserve the error-correction performance of the proposed decoder. Simulation results demonstrate that at the target frame error rate of 10−3 for the RM code of length 256 with 163 information bits, the proposed decoder reduces 6% of the computational complexity and 22% of the decoding latency of the state-of-the-art semi-parallel simplified successive-cancellation decoder with fast Hadamard transform (SSC-FHT) that uses 96 permutations from the full symmetry group of RM codes, while relatively maintaining the error-correction performance and memory consumption of the semi-parallel permuted SSC-FHT decoder. article_processing_charge: No article_type: original arxiv: 1 author: - first_name: Nghia full_name: Doan, Nghia last_name: Doan - first_name: Seyyed Ali full_name: Hashemi, Seyyed Ali last_name: Hashemi - first_name: Marco full_name: Mondelli, Marco id: 27EB676C-8706-11E9-9510-7717E6697425 last_name: Mondelli orcid: 0000-0002-3242-7020 - first_name: Warren J. full_name: Gross, Warren J. last_name: Gross citation: ama: Doan N, Hashemi SA, Mondelli M, Gross WJ.

In particular, when the number of processing elements P that can perform SSC decoding operations in parallel is limited, as is the case in practice, the latency of SSC decoding is O(N1-1/μ + N/P log2 log2 N/P), where N is the block length of the code and μ is the scaling exponent of the channel. Three direct consequences of this bound are presented. First, in a fully-parallel implementation where P = N/2, the latency of SSC decoding is O(N1-1/μ), which is sublinear in the block length. This recovers a result from our earlier work. Second, in a fully-serial implementation where P = 1, the latency of SSC decoding scales as O(N log2 log2 N). The multiplicative constant is also calculated: we show that the latency of SSC decoding when P = 1 is given by (2 + o(1))N log2 log2 N. Third, in a semi-parallel implementation, the smallest P that gives the same latency as that of the fully-parallel implementation is P = N1/μ. The tightness of our bound on SSC decoding latency and the applicability of the foregoing results is validated through extensive simulations.' acknowledgement: "S. A.

However, organoids usually lack microglia, brain-resident immune cells, which are present in the early embryonic brain and participate in neuronal circuit development. Here, we find IBA1+ microglia-like cells alongside retinal cups between week 3 and 4 in 2.5D culture with an unguided retinal organoid differentiation protocol. Microglia do not infiltrate the neuroectoderm and instead enrich within non-pigmented, 3D-cystic compartments that develop in parallel to the 3D-retinal organoids. When we guide the retinal organoid differentiation with low-dosed BMP4, we prevent cup development and enhance microglia and 3D-cysts formation. Mass spectrometry identifies these 3D-cysts to express mesenchymal and epithelial markers. We confirmed this microglia-preferred environment also within the unguided protocol, providing insight into microglial behavior and migration and offer a model to study how they enter and distribute within the human brain. acknowledged_ssus: - _id: Bio - _id: LifeSc acknowledgement: We thank the scientific service units at ISTA, specifically the lab support facility and imaging & optics facility for their support; Nicolas Armel for performing the Mass Spectrometry.

We even establish the rate of convergence O(ε1/2).\r\nOur approach is based on the gradient flow structure of the Allen-Cahn equation and its limiting motion: Building on the recent concept of \"gradient flow calibrations\" for multiphase mean curvature flow, we introduce a notion of relative entropy for the vectorial Allen-Cahn equation with multi-well potential. This enables us to overcome the limitations of other approaches, e.g. avoiding the need for a stability analysis of the Allen-Cahn operator or additional convergence hypotheses for the energy at positive times." article_number: '2203.17143' article_processing_charge: No arxiv: 1 author: - first_name: Julian L full_name: Fischer, Julian L id: 2C12A0B0-F248-11E8-B48F-1D18A9856A87 last_name: Fischer orcid: 0000-0002-0479-558X - first_name: Alice full_name: Marveggio, Alice id: 25647992-AA84-11E9-9D75-8427E6697425 last_name: Marveggio citation: ama: Fischer JL, Marveggio A.

Here, we identify one key upstream regulator of ventral tail bending in embryos of the ascidian Ciona. We show that during the early tailbud stages, ventral epidermal cells exhibit a boat-shaped morphology (boat cell) with a narrow apical surface where phosphorylated myosin light chain (pMLC) accumulates. We further show that interfering with the function of the BMP ligand Admp led to pMLC localizing to the basal instead of the apical side of ventral epidermal cells and a reduced number of boat cells. Finally, we show that cutting ventral epidermal midline cells at their apex using an ultraviolet laser relaxed ventral tail bending. Based on these results, we propose a previously unreported function for Admp in localizing pMLC to the apical side of ventral epidermal cells, which causes the tail to bend ventrally by resisting antero-posterior notochord extension at the ventral side of the tail. acknowledgement: "iona intestinalis adults were provided by Dr Yutaka Satou (Kyoto University) and Dr Manabu Yoshida (the University of Tokyo) with support from the National Bio-Resource Project of AMED, Japan.

However, the mechanism by which they are quantitatively controlled is unknown. We show that the amount of mature miR-9, a key regulator of neuronal development, increases during zebrafish neurogenesis in a sharp stepwise manner. We characterize the spatiotemporal profile of seven distinct microRNA primary transcripts (pri-mir)-9s that produce the same mature miR-9 and show that they are sequentially expressed during hindbrain neurogenesis. Expression of late-onset pri-mir-9-1 is added on to, rather than replacing, the expression of early onset pri-mir-9-4 and -9-5 in single cells. CRISPR/Cas9 mutation of the late-onset pri-mir-9-1 prevents the developmental increase of mature miR-9, reduces late neuronal differentiation and fails to downregulate Her6 at late stages. Mathematical modelling shows that an adaptive network containing Her6 is insensitive to linear increases in miR-9 but responds to stepwise increases of miR-9. We suggest that a sharp stepwise increase of mature miR-9 is created by sequential and additive temporal activation of distinct loci. This may be a strategy to overcome adaptation and facilitate a transition of Her6 to a new dynamic regime or steady state. acknowledgement: "We are grateful to Dr Tom Pettini for the advice on smiFISH technique and Dr Laure Bally-Cuif for sharing plasmids.

In this paper, we present a detailed mapping of the out-of-plane (OOP) magnetic anisotropy in Sr2IrO4 for different sample orientations using torque magnetometry measurements in the low-magnetic-field region before the isospins are completely ordered. Dominant in-plane anisotropy was identified at low fields, confirming the b axis as an easy magnetization axis. Based on the fitting analysis of the strong uniaxial magnetic anisotropy, we observed that the main anisotropic effect arises from a spin–orbit-coupled magnetic exchange interaction affecting the OOP interaction. The effect of interlayer exchange interaction results in additional anisotropic terms owing to the tilting of the isospins. The results are relevant for understanding OOP magnetic anisotropy and provide a new way to analyze the effects of spin–orbit-coupling and interlayer magnetic exchange interactions. This study provides insight into the understanding of bulk magnetic, magnetotransport, and spintronic behavior on Sr2IrO4 for future studies. acknowledgement: 'YJ was supported by the National Research Foundation of Korea (NRF) (Grant Nos.

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.

Here we present a strategy using finite-element method (FEM) simulations to determine the Green's function of the KPFM probe/insulator/ground system, which allows us to quantitatively extract surface charge. Testing our approach with synthetic data, we find that accounting for the atomic force microscope (AFM) tip, cone, and cantilever is necessary to recover a known input and that existing methods lead to gross miscalculation or even the incorrect sign of the underlying charge. Applying it to experimental data, we demonstrate its capacity to extract realistic surface charge densities and fine details from contact-charged surfaces. Our method gives a straightforward recipe to convert qualitative KPFM voltage data into quantitative charge data over a range of experimental conditions, enabling quantitative CE at the nanoscale. acknowledged_ssus: - _id: M-Shop - _id: NanoFab - _id: ScienComp acknowledgement: "This project has received funding from the European Research Council (ERC) under the European Union’s Horizon 2020 research and innovation programme (Grant Agreement\r\nNo. 949120).

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.

While its phenotypic spectrum often encompasses macrocephaly, implicating cortical abnormalities, how CHD8 haploinsufficiency affects neurodevelopmental is unclear. Here, employing human cerebral organoids, we find that CHD8 haploinsufficiency disrupted neurodevelopmental trajectories with an accelerated and delayed generation of, respectively, inhibitory and excitatory neurons that yields, at days 60 and 120, symmetrically opposite expansions in their proportions. This imbalance is consistent with an enlargement of cerebral organoids as an in vitro correlate of patients’ macrocephaly. Through an isogenic design of patient-specific mutations and mosaic organoids, we define genotype-phenotype relationships and uncover their cell-autonomous nature. Our results define cell-type-specific CHD8-dependent molecular defects related to an abnormal program of proliferation and alternative splicing. By identifying cell-type-specific effects of CHD8 mutations, our study uncovers reproducible developmental alterations that may be employed for neurodevelopmental disease modeling. acknowledged_ssus: - _id: Bio - _id: LifeSc acknowledgement: We thank Farnaz Freeman for technical assistance.

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.

Yet the mechanisms immune cells utilize to negotiate tissue barriers in living organisms are not well understood, and a role for cortical actin has not been examined. Here, we find that the tissue invasion of Drosophila macrophages, also known as plasmatocytes or hemocytes, utilizes enhanced cortical F-actin levels stimulated by the Drosophila member of the fos proto oncogene transcription factor family (Dfos, Kayak). RNA sequencing analysis and live imaging show that Dfos enhances F-actin levels around the entire macrophage surface by increasing mRNA levels of the membrane spanning molecular scaffold tetraspanin TM4SF, and the actin cross-linking filamin Cheerio, which are themselves required for invasion. Both the filamin and the tetraspanin enhance the cortical activity of Rho1 and the formin Diaphanous and thus the assembly of cortical actin, which is a critical function since expressing a dominant active form of Diaphanous can rescue the Dfos macrophage invasion defect. In vivo imaging shows that Dfos enhances the efficiency of the initial phases of macrophage tissue entry. Genetic evidence argues that this Dfos-induced program in macrophages counteracts the constraint produced by the tension of surrounding tissues and buffers the properties of the macrophage nucleus from affecting tissue entry. We thus identify strengthening the cortical actin cytoskeleton through Dfos as a key process allowing efficient forward movement of an immune cell into surrounding tissues.
