[{"abstract":[{"text":"The coherent optical manipulation of solids is emerging as a promising way to engineer novel quantum states of matter. The strong time-periodic potential of intense laser light can be used to generate hybrid photon-electron states. Interaction of light with Bloch states leads to Floquet-Bloch states, which are essential in realizing new photo-induced quantum phases. Similarly, dressing of free-electron states near the surface of a solid generates Volkov states, which are used to study nonlinear optics in atoms and semiconductors. The interaction of these two dynamic states with each other remains an open experimental problem. Here we use time- and angle-resolved photoemission spectroscopy (Tr-ARPES) to selectively study the transition between these two states on the surface of the topological insulator Bi2Se3. We find that the coupling between the two strongly depends on the electron momentum, providing a route to enhance or inhibit it. Moreover, by controlling the light polarization we can negate Volkov states to generate pure Floquet-Bloch states. This work establishes a systematic path for the coherent manipulation of solids via light-matter interaction.","lang":"eng"}],"author":[{"last_name":"Mahmood","first_name":"Fahad","full_name":"Mahmood, Fahad"},{"first_name":"Ching","full_name":"Chan, Ching","last_name":"Chan"},{"id":"45E67A2A-F248-11E8-B48F-1D18A9856A87","last_name":"Alpichshev","orcid":"0000-0002-7183-5203","full_name":"Alpichshev, Zhanybek","first_name":"Zhanybek"},{"last_name":"Gardner","first_name":"Dillon","full_name":"Gardner, Dillon"},{"last_name":"Lee","first_name":"Young","full_name":"Lee, Young"},{"last_name":"Lee","full_name":"Lee, Patrick","first_name":"Patrick"},{"last_name":"Gedik","full_name":"Gedik, Nuh","first_name":"Nuh"}],"main_file_link":[{"open_access":"1","url":"https://arxiv.org/abs/1512.05714"}],"oa":1,"publisher":"Nature Publishing Group","date_created":"2018-12-11T11:46:11Z","publication":"Nature Physics","month":"04","doi":"10.1038/nphys3609","oa_version":"None","extern":"1","citation":{"ama":"Mahmood F, Chan C, Alpichshev Z, et al.

Recently, it has become clear that a charge density wave (CDW) phase exists within the pseudogap regime. This CDW coexists and competes with superconductivity (SC) below the transition temperature Tc, suggesting that these two orders are intimately related. Here we show that the condensation of the superfluid from this unconventional precursor is reflected in deviations from the predictions of BSC theory regarding the recombination rate of quasiparticles. We report a detailed investigation of the quasiparticle (QP) recombination lifetime, τqp, as a function of temperature and magnetic field in underdoped HgBa2CuO4+δ (Hg-1201) and YBa2Cu3O6+x (YBCO) single crystals by ultrafast time-resolved reflectivity. We find that τqp (T) exhibits a local maximum in a small temperature window near Tc that is prominent in underdoped samples with coexisting charge order and vanishes with application of a small magnetic field. We explain this unusual, non-BCS behavior by positing that Tc marks a transition from phase-fluctuating SC/CDW composite order above to a SC/CDW condensate below. Our results suggest that the superfluid in underdoped cuprates is a condensate of coherently-mixed particle-particle and particle-hole pairs.","lang":"eng"}],"publisher":"Nature Publishing Group","month":"04","date_created":"2018-12-11T11:46:12Z","publication":"Scientific Reports","publication_status":"published","_id":"390","intvolume":"         6","type":"journal_article","doi":"10.1038/srep23610","oa_version":"None","extern":"1","citation":{"ama":"Hinton J, Thewalt E, Alpichshev Z, et al.

Sodium dodecyl sulfate-digested freeze-fracture replica labeling (SDS-FRL) is a powerful electron microscopy method to study high-resolution two-dimensional distribution of transmembrane proteins and their tightly associated proteins on platinum-carbon replica. During treatment with SDS, unfixed proteins and intracellular organelle are dissolved and integral membrane proteins captured and stabilized by carbon and platinum deposition are denatured, retaining most of their antigenicity, and exposed on exoplasmic and protoplasmic surfaces of lipid monolayers. The exposure of these antigens on the surface of replica facilitates the accessibility of antibodies and therefore provides higher labeling efficiency than those obtained with other immunoelectron microscopy techniques. In this chapter, we describe the protocols of SDS-FRL adapted for mammalian brain samples and an additional procedure for fluorescence-guided electron microscopy for replica immunolabeling."}],"author":[{"full_name":"Harada, Harumi","first_name":"Harumi","id":"2E55CDF2-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0001-7429-7896","last_name":"Harada"},{"id":"499F3ABC-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0001-8761-9444","last_name":"Shigemoto","full_name":"Shigemoto, Ryuichi","first_name":"Ryuichi"}],"quality_controlled":"1","date_published":"2016-02-02T00:00:00Z","user_id":"ba8df636-2132-11f1-aed0-ed93e2281fdd","status":"public","acknowledgement":"We thank Mitsuru Ikeda for preparing replica images used in Fig. 2.","year":"2016","publication_identifier":{"isbn":["9781493930630"],"eissn":["1940-6045"],"eisbn":["9781493930647"],"issn":["0893-2336"]},"day":"02"},{"user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","status":"public","date_published":"2016-09-22T00:00:00Z","related_material":{"record":[{"id":"7977","relation":"popular_science"},{"relation":"dissertation_contains","status":"public","id":"7996"}]},"publist_id":"5941","tmp":{"name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","image":"/images/cc_by.png","short":"CC BY (4.0)"},"pubrep_id":"664","language":[{"iso":"eng"}],"page":"6879 - 6885","doi":"10.1021/acs.nanolett.6b02715","oa_version":"Published Version","citation":{"short":"H.

production requires the establishment of an electrochemical proton gradient across the inner mitochondrial membrane. Mitochondrial uncouplers dissipate this proton gradient and disrupt numerous cellular processes, including vesicular trafficking, mainly through energy depletion. Here we show that Endosidin9 (ES9), a novel mitochondrial uncoupler, is a potent inhibitor of clathrin-mediated endocytosis (CME) in different systems and that ES9 induces inhibition of CME not because of its effect on cellular ATP, but rather due to its protonophore activity that leads to cytoplasm acidification. We show that the known tyrosine kinase inhibitor tyrphostinA23, which is routinely used to block CME, displays similar properties, thus questioning its use as a specific inhibitor of cargo recognition by the AP-2 adaptor complex via tyrosine motif-based endocytosis signals. Furthermore, we show that cytoplasm acidification dramatically affects the dynamics and recruitment of clathrin and associated adaptors, and leads to reduction of phosphatidylinositol 4,5-biphosphate from the plasma membrane."}],"ec_funded":1,"date_created":"2018-12-11T11:51:30Z","month":"06","publication":"Nature Communications","oa":1,"_id":"1346","intvolume":"         7","doi":"10.1038/ncomms11710","oa_version":"Published Version","citation":{"mla":"Dejonghe, Wim, et al. “Mitochondrial Uncouplers Inhibit Clathrin-Mediated Endocytosis Largely through Cytoplasmic Acidification.” <i>Nature Communications</i>, vol. 7, 11710, Nature Publishing Group, 2016, doi:<a href=\"https://doi.org/10.1038/ncomms11710\">10.1038/ncomms11710</a>.","ista":"Dejonghe W, Kuenen S, Mylle E, Vasileva MK, Keech O, Viotti C, Swerts J, Fendrych M, Ortiz Morea F, Mishev K, Delang S, Scholl S, Zarza X, Heilmann M, Kourelis J, Kasprowicz J, Nguyen L, Drozdzecki A, Van Houtte I, Szatmári A, Majda M, Baisa G, Bednarek S, Robert S, Audenaert D, Testerink C, Munnik T, Van Damme D, Heilmann I, Schumacher K, Winne J, Friml J, Verstreken P, Russinova E. 2016.

Limited specificity may lead to crosstalk: a regulatory state in which a gene is either incorrectly activated due to noncognate TF–DNA interactions or remains erroneously inactive. As each TF can have numerous interactions with noncognate cis-regulatory elements, crosstalk is inherently a global problem, yet has previously not been studied as such. We construct a theoretical framework to analyse the effects of global crosstalk on gene regulation. We find that crosstalk presents a significant challenge for organisms with low-specificity TFs, such as metazoans. Crosstalk is not easily mitigated by known regulatory schemes acting at equilibrium, including variants of cooperativity and combinatorial regulation. Our results suggest that crosstalk imposes a previously unexplored global constraint on the functioning and evolution of regulatory networks, which is qualitatively distinct from the known constraints that act at the level of individual gene regulatory elements."}],"ec_funded":1,"scopus_import":"1","article_number":"12307","status":"public","user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","date_published":"2016-08-04T00:00:00Z","related_material":{"record":[{"id":"6071","status":"public","relation":"dissertation_contains"}]},"publist_id":"5887","pubrep_id":"627","tmp":{"name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","image":"/images/cc_by.png","short":"CC BY (4.0)"},"has_accepted_license":"1","date_updated":"2026-04-08T13:54:24Z","department":[{"_id":"GaTk"},{"_id":"NiBa"},{"_id":"CaGu"}],"title":"Intrinsic limits to gene regulation by global crosstalk","article_processing_charge":"No","file":[{"file_name":"IST-2016-627-v1+1_ncomms12307.pdf","creator":"system","content_type":"application/pdf","relation":"main_file","file_id":"4919","date_created":"2018-12-12T10:12:01Z","file_size":861805,"checksum":"fe3f3a1526d180b29fe691ab11435b78","access_level":"open_access","date_updated":"2020-07-14T12:44:46Z"},{"file_size":1084703,"file_id":"4920","date_created":"2018-12-12T10:12:02Z","relation":"main_file","file_name":"IST-2016-627-v1+2_ncomms12307-s1.pdf","creator":"system","content_type":"application/pdf","date_updated":"2020-07-14T12:44:46Z","access_level":"open_access","checksum":"164864a1a675f3ad80e9917c27aba07f"}],"type":"journal_article","publication_status":"published","publisher":"Nature Publishing Group","ddc":["576"],"quality_controlled":"1","author":[{"full_name":"Friedlander, Tamar","first_name":"Tamar","id":"36A5845C-F248-11E8-B48F-1D18A9856A87","last_name":"Friedlander"},{"full_name":"Prizak, Roshan","first_name":"Roshan","id":"4456104E-F248-11E8-B48F-1D18A9856A87","last_name":"Prizak"},{"first_name":"Calin C","full_name":"Guet, Calin C","last_name":"Guet","orcid":"0000-0001-6220-2052","id":"47F8433E-F248-11E8-B48F-1D18A9856A87"},{"first_name":"Nicholas H","full_name":"Barton, Nicholas H","orcid":"0000-0002-8548-5240","last_name":"Barton","id":"4880FE40-F248-11E8-B48F-1D18A9856A87"},{"id":"3D494DCA-F248-11E8-B48F-1D18A9856A87","last_name":"Tkacik","orcid":"0000-0002-6699-1455","full_name":"Tkacik, Gasper","first_name":"Gasper"}],"project":[{"call_identifier":"FP7","grant_number":"291734","_id":"25681D80-B435-11E9-9278-68D0E5697425","name":"International IST Postdoc Fellowship Programme"},{"_id":"25B07788-B435-11E9-9278-68D0E5697425","name":"Limits to selection in biology and in evolutionary computation","grant_number":"250152","call_identifier":"FP7"},{"name":"Biophysics of information processing in gene regulation","_id":"254E9036-B435-11E9-9278-68D0E5697425","call_identifier":"FWF","grant_number":"P28844-B27"}],"external_id":{"isi":["000380858400001"]},"file_date_updated":"2020-07-14T12:44:46Z","isi":1,"day":"04","volume":7,"year":"2016"},{"publisher":"Cell Press","author":[{"full_name":"Schwayer, Cornelia","first_name":"Cornelia","id":"3436488C-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0001-5130-2226","last_name":"Schwayer"},{"last_name":"Sikora","id":"2F74BCDE-F248-11E8-B48F-1D18A9856A87","first_name":"Mateusz K","full_name":"Sikora, Mateusz K"},{"first_name":"Jana","full_name":"Slovakova, Jana","last_name":"Slovakova","id":"30F3F2F0-F248-11E8-B48F-1D18A9856A87"},{"last_name":"Kardos","id":"4039350E-F248-11E8-B48F-1D18A9856A87","first_name":"Roland","full_name":"Kardos, Roland"},{"last_name":"Heisenberg","orcid":"0000-0002-0912-4566","id":"39427864-F248-11E8-B48F-1D18A9856A87","first_name":"Carl-Philipp J","full_name":"Heisenberg, Carl-Philipp J"}],"quality_controlled":"1","article_processing_charge":"No","department":[{"_id":"CaHe"}],"title":"Actin rings of power","date_updated":"2026-04-08T13:55:28Z","issue":"6","publication_status":"published","type":"journal_article","isi":1,"year":"2016","volume":37,"day":"20","external_id":{"isi":["000378204200005"]},"month":"06","date_created":"2018-12-11T11:50:07Z","publication":"Developmental Cell","scopus_import":"1","page":"493 - 506","language":[{"iso":"eng"}],"_id":"1096","intvolume":"        37","doi":"10.1016/j.devcel.2016.05.024","oa_version":"None","citation":{"ista":"Schwayer C, Sikora MK, Slovakova J, Kardos R, Heisenberg C-PJ. 2016.

[GGSW13]. A WE scheme is defined for some NP language L and lets a sender encrypt messages relative to instances x. A ciphertext for x can be decrypted using w witnessing x ∈ L, but hides the message if x ∈ L. Garg et al. construct WE from multilinear maps and give another construction [GGH+13b] using indistinguishability obfuscation (iO) for circuits. Due to the reliance on such heavy tools, WE can cur- rently hardly be implemented on powerful hardware and will unlikely be realizable on constrained devices like smart cards any time soon. We construct a WE scheme where encryption is done by simply computing a Naor-Yung ciphertext (two CPA encryptions and a NIZK proof). To achieve this, our scheme has a setup phase, which outputs public parameters containing an obfuscated circuit (only required for decryption), two encryption keys and a common reference string (used for encryption). This setup need only be run once, and the parame- ters can be used for arbitrary many encryptions. Our scheme can also be turned into a functional WE scheme, where a message is encrypted w.r.t. a statement and a function f, and decryption with a witness w yields f (m, w). Our construction is inspired by the functional encryption scheme by Garg et al. and we prove (selective) security assuming iO and statistically simulation-sound NIZK. We give a construction of the latter in bilinear groups and combining it with ElGamal encryption, our ciphertexts are of size 1.3 kB at a 128-bit security level and can be computed on a smart card.","lang":"eng"}],"ec_funded":1,"oa":1,"date_created":"2018-12-11T11:50:50Z","month":"06"},{"citation":{"ama":"Abusalah HM, Fuchsbauer G, Pietrzak KZ.

Although red light offers deep-tissue penetration and minimal phototoxicity, very few red-light-sensitive optogenetic methods are currently available. We have now developed a red-light-induced homodimerization domain. We first showed that an optimized sensory domain of the cyanobacterial phytochrome 1 can be expressed robustly and without cytotoxicity in human cells. We then applied this domain to induce the dimerization of two receptor tyrosine kinases—the fibroblast growth factor receptor 1 and the neurotrophin receptor trkB. This new optogenetic method was then used to activate the MAPK/ERK pathway non-invasively in mammalian tissue and in multicolor cell-signaling experiments. The light-controlled dimerizer and red-light-activated receptor tyrosine kinases will prove useful to regulate a variety of cellular processes with light. Go deep with red: The sensory domain (S) of the cyanobacterial phytochrome 1 (CPH1) was repurposed to induce the homodimerization of proteins in living cells by red light. By using this domain, light-activated protein kinases were engineered that can be activated orthogonally from many fluorescent proteins and through mammalian tissue.

The transition from a full boundary element method to our faster variant is possible at the beginning of any time step. This allows us to build a hybrid method, which uses the expensive but more accurate BEM while the number of degrees of freedom is low, and uses the fast method once that number exceeds a given threshold as the crack geometry becomes more complicated. Furthermore, we integrate this fracture simulation with a standard rigid-body solver. Our rigid-body coupling solves a Neumann boundary value problem by carefully separating translational, rotational and deformational components of the collision forces and then applying a Tikhonov regularizer to the resulting linear system. We show that our method produces physically reasonable results in standard test cases and is capable of dealing with complex scenes faster than previous finite- or boundary element approaches."}],"language":[{"iso":"eng"}],"corr_author":"1","_id":"1362","intvolume":"        35","doi":"10.1145/2897824.2925902","oa_version":"Published Version","citation":{"ista":"Hahn D, Wojtan C. 2016.

The mechanism is based on the balance between methyltransferase (M) and cognate restriction endonuclease (R). M tags endogenous DNA as self by methylating short specific DNA sequences called restriction sites, whereas R recognizes unmethylated restriction sites as non-self and introduces a double-stranded DNA break [3]. Restriction sites are significantly underrepresented in prokaryotic genomes [4-7], suggesting that the discrimination mechanism is imperfect and occasionally leads to autoimmunity due to self-DNA cleavage (self-restriction) [8]. Furthermore, RM systems can promote DNA recombination [9] and contribute to genetic variation in microbial populations, thus facilitating adaptive evolution [10]. However, cleavage of self-DNA by RM systems as elements shaping prokaryotic genomes has not been directly detected, and its cause, frequency, and outcome are unknown. We quantify self-restriction caused by two RM systems of Escherichia coli and find that, in agreement with levels of restriction site avoidance, EcoRI, but not EcoRV, cleaves self-DNA at a measurable rate. Self-restriction is a stochastic process, which temporarily induces the SOS response, and is followed by DNA repair, maintaining cell viability. We find that RM systems with higher restriction efficiency against bacteriophage infections exhibit a higher rate of self-restriction, and that this rate can be further increased by stochastic imbalance between R and M. Our results identify molecular noise in RM systems as a factor shaping prokaryotic genomes.","lang":"eng"}],"scopus_import":"1","month":"02","date_created":"2018-12-11T11:50:54Z","publication":"Current Biology","intvolume":"        26","_id":"1243","citation":{"mla":"Pleska, Maros, et al. “Bacterial Autoimmunity Due to a Restriction-Modification System.” <i>Current Biology</i>, vol. 26, no. 3, Cell Press, 2016, pp. 404–09, doi:<a href=\"https://doi.org/10.1016/j.cub.2015.12.041\">10.1016/j.cub.2015.12.041</a>.","ista":"Pleska M, Qian L, Okura R, Bergmiller T, Wakamoto Y, Kussell E, Guet CC. 2016.

The qualitative analysis problem given a POMDP and an objective asks whether there is a strategy (policy) to ensure that the objective is satisfied almost surely (with probability 1), resp. with positive probability (with probability greater than 0). For POMDPs with limit-average payoff, where a reward value in the interval [0,1] is associated to every transition, and the payoff of an infinite path is the long-run average of the rewards, we consider two types of path constraints: (i) a quantitative limit-average constraint defines the set of paths where the payoff is at least a given threshold L1 = 1. Our main results for qualitative limit-average constraint under almost-sure winning are as follows: (i) the problem of deciding the existence of a finite-memory controller is EXPTIME-complete; and (ii) the problem of deciding the existence of an infinite-memory controller is undecidable. For quantitative limit-average constraints we show that the problem of deciding the existence of a finite-memory controller is undecidable. We present a prototype implementation of our EXPTIME algorithm. For POMDPs with w-regular conditions specified as parity objectives, while the qualitative analysis problems are known to be undecidable even for very special case of parity objectives, we establish decidability (with optimal complexity) of the qualitative analysis problems for POMDPs with parity objectives under finite-memory strategies. We establish optimal (exponential) memory bounds and EXPTIME-completeness of the qualitative analysis problems under finite-memory strategies for POMDPs with parity objectives. Based on our theoretical algorithms we also present a practical approach, where we design heuristics to deal with the exponential complexity, and have applied our implementation on a number of well-known POMDP examples for robotics applications. For POMDPs with a set of target states and an integer cost associated with every transition, we study the optimization objective that asks to minimize the expected total cost of reaching a state in the target set, while ensuring that the target set is reached almost surely. We show that for general integer costs approximating the optimal cost is undecidable. For positive costs, our results are as follows: (i) we establish matching lower and upper bounds for the optimal cost, both double and exponential in the POMDP state space size; (ii) we show that the problem of approximating the optimal cost is decidable and present approximation algorithms that extend existing algorithms for POMDPs with finite-horizon objectives. We show experimentally that it performs well in many examples of interest. We study more deeply the problem of almost-sure reachability, where  given a set of target states, the question is to decide whether there is a strategy to ensure that the target set is reached almost surely. While in general the problem EXPTIME-complete, in many practical cases strategies with a small amount of memory suffice. Moreover, the existing solution to the problem is explicit, which first requires to construct explicitly an exponential reduction to a belief-support MDP. We first study the existence of observation-stationary strategies, which is NP-complete, and then small-memory strategies. We present a symbolic algorithm by an efficient encoding to SAT and using a SAT solver for the problem. We report experimental results demonstrating the scalability of our symbolic (SAT-based) approach. Decentralized POMDPs (DEC-POMDPs) extend POMDPs to a multi-agent setting, where several agents operate in an uncertain environment independently to achieve a joint objective. In this work we consider Goal DEC-POMDPs, where given a set of target states, the objective is to ensure that the target set is reached with minimal cost. We consider the indefinite-horizon (infinite-horizon with either discounted-sum, or undiscounted-sum, where absorbing goal states have zero-cost) problem. We present a new and novel method to solve the problem that extends methods for finite-horizon DEC-POMDPs and the real-time dynamic programming approach for POMDPs. We present experimental results on several examples, and show that our approach presents promising results. In the end we present a short summary of a few other results related to verification of MDPs and POMDPs.","lang":"eng"}]},{"date_updated":"2026-04-08T14:28:53Z","has_accepted_license":"1","article_processing_charge":"No","title":"Quantitative analysis of haptotactic cell migration","department":[{"_id":"MiSi"}],"file":[{"date_updated":"2019-08-13T10:55:35Z","checksum":"e3cd6b28f9c5cccb8891855565a2dade","access_level":"closed","date_created":"2019-08-13T10:55:35Z","file_id":"6813","file_size":32044069,"content_type":"application/pdf","creator":"dernst","file_name":"Thesis_JSchwarz_final.pdf","relation":"main_file"},{"file_size":8396717,"success":1,"file_id":"9181","date_created":"2021-02-22T11:43:14Z","relation":"main_file","file_name":"2016_Thesis_JSchwarz.pdf","creator":"dernst","content_type":"application/pdf","date_updated":"2021-02-22T11:43:14Z","access_level":"open_access","checksum":"c3dbe219acf87eed2f46d21d5cca00de"}],"publication_status":"published","type":"dissertation","publisher":"Institute of Science and Technology Austria","ddc":["570"],"author":[{"last_name":"Schwarz","id":"346C1EC6-F248-11E8-B48F-1D18A9856A87","first_name":"Jan","full_name":"Schwarz, Jan"}],"file_date_updated":"2021-02-22T11:43:14Z","acknowledgement":"First, I would like to thank Michael Sixt for being a great supervisor, mentor and\r\nscientist.

Despite its importance, basic questions regarding force transduction\r\nor directional sensing are still heavily investigated. Directed migration of cells\r\nguided by immobilized guidance cues - haptotaxis - occurs in key-processes,\r\nsuch as embryonic development and immunity (Middleton et al., 1997; Nguyen\r\net al., 2000; Thiery, 1984; Weber et al., 2013). Immobilized guidance cues\r\ncomprise adhesive ligands, such as collagen and fibronectin (Barczyk et al.,\r\n2009), or chemokines - the main guidance cues for migratory leukocytes\r\n(Middleton et al., 1997; Weber et al., 2013). While adhesive ligands serve as\r\nattachment sites guiding cell migration (Carter, 1965), chemokines instruct\r\nhaptotactic migration by inducing adhesion to adhesive ligands and directional\r\nguidance (Rot and Andrian, 2004; Schumann et al., 2010). Quantitative analysis\r\nof the cellular response to immobilized guidance cues requires in vitro assays\r\nthat foster cell migration, offer accurate control of the immobilized cues on a\r\nsubcellular scale and in the ideal case closely reproduce in vivo conditions. The\r\nexploration of haptotactic cell migration through design and employment of such\r\nassays represents the main focus of this work.\r\nDendritic cells (DCs) are leukocytes, which after encountering danger\r\nsignals such as pathogens in peripheral organs instruct naïve T-cells and\r\nconsequently the adaptive immune response in the lymph node (Mellman and\r\nSteinman, 2001). To reach the lymph node from the periphery, DCs follow\r\nhaptotactic gradients of the chemokine CCL21 towards lymphatic vessels\r\n(Weber et al., 2013). Questions about how DCs interpret haptotactic CCL21\r\ngradients have not yet been addressed. The main reason for this is the lack of\r\nan assay that offers diverse haptotactic environments, hence allowing the study\r\nof DC migration as a response to different signals of immobilized guidance cue.\r\nIn this work, we developed an in vitro assay that enables us to\r\nquantitatively assess DC haptotaxis, by combining precisely controllable\r\nchemokine photo-patterning with physically confining migration conditions. With this tool at hand, we studied the influence of CCL21 gradient properties and\r\nconcentration on DC haptotaxis. We found that haptotactic gradient sensing\r\ndepends on the absolute CCL21 concentration in combination with the local\r\nsteepness of the gradient. Our analysis suggests that the directionality of\r\nmigrating DCs is governed by the signal-to-noise ratio of CCL21 binding to its\r\nreceptor CCR7. Moreover, the haptotactic CCL21 gradient formed in vivo\r\nprovides an optimal shape for DCs to recognize haptotactic guidance cue.\r\nBy reconstitution of the CCL21 gradient in vitro we were also able to\r\nstudy the influence of CCR7 signal termination on DC haptotaxis. To this end,\r\nwe used DCs lacking the G-protein coupled receptor kinase GRK6, which is\r\nresponsible for CCL21 induced CCR7 receptor phosphorylation and\r\ndesensitization (Zidar et al., 2009). We found that CCR7 desensitization by\r\nGRK6 is crucial for maintenance of haptotactic CCL21 gradient sensing in vitro\r\nand confirm those observations in vivo.\r\nIn the context of the organism, immobilized haptotactic guidance cues\r\noften coincide and compete with soluble chemotactic guidance cues. During\r\nwound healing, fibroblasts are exposed and influenced by adhesive cues and\r\nsoluble factors at the same time (Wu et al., 2012; Wynn, 2008). Similarly,\r\nmigrating DCs are exposed to both, soluble chemokines (CCL19 and truncated\r\nCCL21) inducing chemotactic behavior as well as the immobilized CCL21. To\r\nquantitatively assess these complex coinciding immobilized and soluble\r\nguidance cues, we implemented our chemokine photo-patterning technique in a\r\nmicrofluidic system allowing for chemotactic gradient generation. To validate\r\nthe assay, we observed DC migration in competing CCL19/CCL21\r\nenvironments.\r\nAdhesiveness guided haptotaxis has been studied intensively over the\r\nlast century. However, quantitative studies leading to conceptual models are\r\nlargely missing, again due to the lack of a precisely controllable in vitro assay. A\r\nrequirement for such an in vitro assay is that it must prevent any uncontrolled\r\ncell adhesion. This can be accomplished by stable passivation of the surface. In\r\naddition, controlled adhesion must be sustainable, quantifiable and dose\r\ndependent in order to create homogenous gradients. Therefore, we developed a novel covalent photo-patterning technique satisfying all these needs. In\r\ncombination with a sustainable poly-vinyl alcohol (PVA) surface coating we\r\nwere able to generate gradients of adhesive cue to direct cell migration. This\r\napproach allowed us to characterize the haptotactic migratory behavior of\r\nzebrafish keratocytes in vitro. Furthermore, defined patterns of adhesive cue\r\nallowed us to control for cell shape and growth on a subcellular scale."}],"OA_place":"publisher","supervisor":[{"full_name":"Sixt, Michael K","first_name":"Michael K","id":"41E9FBEA-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-6620-9179","last_name":"Sixt"}],"degree_awarded":"PhD","user_id":"ba8df636-2132-11f1-aed0-ed93e2281fdd","status":"public","date_published":"2016-07-01T00:00:00Z","acknowledged_ssus":[{"_id":"Bio"},{"_id":"PreCl"},{"_id":"LifeSc"}],"publist_id":"6231","publication_identifier":{"issn":["2663-337X"]}},{"ddc":["004","005","006","532","621"],"publisher":"Institute of Science and Technology Austria","author":[{"full_name":"Bojsen-Hansen, Morten","first_name":"Morten","id":"439F0C8C-F248-11E8-B48F-1D18A9856A87","last_name":"Bojsen-Hansen","orcid":"0000-0002-4417-3224"}],"title":"Tracking, correcting and absorbing water surface waves","department":[{"_id":"ChWo"}],"article_processing_charge":"No","has_accepted_license":"1","date_updated":"2026-04-08T14:24:06Z","type":"dissertation","publication_status":"published","file":[{"date_created":"2018-12-12T10:13:02Z","file_id":"4982","file_size":13869345,"creator":"system","content_type":"application/pdf","file_name":"IST-2016-640-v1+1_2016_Bojsen-Hansen_TCaAWSW.pdf","relation":"main_file","date_updated":"2018-12-12T10:13:02Z","access_level":"open_access"}],"alternative_title":["ISTA Thesis"],"acknowledgement":"First and foremost I would like to thank Chris.

On the one hand,\r\nthere is a healthy injection of pragmatism coming from the visual effects industry\r\nthat want robust algorithms that work so they can produce results at an increasingly\r\nfrantic pace. On the other hand, they must always try to push the envelope and\r\nachieve the impossible to wow their audiences in the next blockbuster, which means\r\nthat the industry has not succumb to conservatism, and there is plenty of room to\r\ntry out new and crazy ideas if there is a chance that it will pan into something\r\nuseful.\r\nWater simulation has been in visual effects for decades, however it still remains\r\nextremely challenging because of its high computational cost and difficult artdirectability.\r\nThe work in this thesis tries to address some of these difficulties.\r\nSpecifically, we make the following three novel contributions to the state-of-the-art\r\nin water simulation for visual effects.\r\nFirst, we develop the first algorithm that can convert any sequence of closed\r\nsurfaces in time into a moving triangle mesh. State-of-the-art methods at the time\r\ncould only handle surfaces with fixed connectivity, but we are the first to be able to\r\nhandle surfaces that merge and split apart. This is important for water simulation\r\npractitioners, because it allows them to convert splashy water surfaces extracted\r\nfrom particles or simulated using grid-based level sets into triangle meshes that can\r\nbe either textured and enhanced with extra surface dynamics as a post-process.\r\nWe also apply our algorithm to other phenomena that merge and split apart, such\r\nas morphs and noisy reconstructions of human performances.\r\nSecond, we formulate a surface-based energy that measures the deviation of a\r\nwater surface froma physically valid state. Such discrepancies arise when there is a\r\nmismatch in the degrees of freedom between the water surface and the underlying\r\nphysics solver. This commonly happens when practitioners use a moving triangle\r\nmesh with a grid-based physics solver, or when high-resolution grid-based surfaces\r\nare combined with low-resolution physics. Following the direction of steepest\r\ndescent on our surface-based energy, we can either smooth these artifacts or turn\r\nthem into high-resolution waves by interpreting the energy as a physical potential.\r\nThird, we extend state-of-the-art techniques in non-reflecting boundaries to handle spatially and time-varying background flows. This allows a novel new\r\nworkflow where practitioners can re-simulate part of an existing simulation, such\r\nas removing a solid obstacle, adding a new splash or locally changing the resolution.\r\nSuch changes can easily lead to new waves in the re-simulated region that would\r\nreflect off of the new simulation boundary, effectively ruining the illusion of a\r\nseamless simulation boundary between the existing and new simulations. Our\r\nnon-reflecting boundaries makes sure that such waves are absorbed.","lang":"eng"}],"page":"114","language":[{"iso":"eng"}],"corr_author":"1","_id":"1122","citation":{"mla":"Bojsen-Hansen, Morten. <i>Tracking, Correcting and Absorbing Water Surface Waves</i>.

In particular, we are interested in maps f : K → Rd  that have no global r -fold intersection points, i.e., no r -fold points with preimages in r pairwise disjoint  simplices of K , and we seek necessary and sufficient conditions for the existence of such maps.\r\n\r\nWe present higher-multiplicity analogues of several classical results for embeddings, in particular of the completeness of the Van Kampen obstruction  for embeddability of k -dimensional\r\ncomplexes into R2k , k ≥ 3. Speciffically, we show that under suitable restrictions on the dimensions(viz., if dimK  = (r ≥ 1)k  and d  = rk \\ for some k ≥ 3), a well-known deleted product criterion (DPC ) is not only necessary but also sufficient for the existence of maps without global r -fold points. Our main technical tool is a higher-multiplicity version of the classical Whitney trick , by which pairs of isolated r -fold points of opposite sign  can be eliminated by local modiffications of the map, assuming codimension d – dimK ≥ 3.\r\n\r\nAn important guiding idea for our work was that suffciency of the DPC, together with an old\r\nresult of Özaydin's on the existence of equivariant maps, might yield an approach to disproving the remaining open cases of the the long-standing topological Tverberg conjecture , i.e., to construct maps from the N -simplex σN  to Rd  without r-Tverberg points when r not a prime power  and\r\nN  = (d  + 1)(r – 1). Unfortunately, our proof of the sufficiency of the DPC requires codimension d – dimK ≥ 3, which is not satisfied for K  = σN .\r\n\r\nIn 2015, Frick [16] found a very elegant way to overcome this \\codimension 3 obstacle&quot; and\r\nto construct the first counterexamples to the topological Tverberg conjecture for all parameters(d; r ) with d ≥ 3r  + 1 and r  not a prime power, by a reduction1  to a suitable lower-dimensional skeleton, for which the codimension 3 restriction is satisfied and maps without r -Tverberg points exist by Özaydin's result and sufficiency of the DPC.\r\n\r\nIn this thesis, we present a different construction (which does not use the constraint method) that yields counterexamples for d ≥ 3r , r  not a prime power.
