Our library faithfully implements variants of stochastic quantization that guarantee convergence at low precision, and supports data formats from 4-bit quantized to 32-bit IEEE-754 on current Intel processors. In particular, we show that 4-bit can be implemented efficiently using Intel AVX despite the lack of native support for this data format. Experimental results with dot product, matrix-vector multiplication (MVM), gradient descent (GD), and iterative hard thresholding (IHT) demonstrate that the attainable speedups are in many cases close to linear with respect to the reduction of precision due to reduced data movement. Finally, for GD and IHT, we show examples of absolute speedup achieved by 4-bit versus 32-bit, by iterating until a given target error is achieved.","lang":"eng"}],"article_number":"8598402","author":[{"last_name":"Stojanov","first_name":"Alen","full_name":"Stojanov, Alen"},{"first_name":"Tyler Michael","last_name":"Smith","full_name":"Smith, Tyler Michael"},{"full_name":"Alistarh, Dan-Adrian","id":"4A899BFC-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0003-3650-940X","last_name":"Alistarh","first_name":"Dan-Adrian"},{"first_name":"Markus","last_name":"Puschel","full_name":"Puschel, Markus"}],"date_updated":"2023-09-19T14:41:51Z","conference":{"location":"Cape Town, South Africa","start_date":"2018-10-21","name":"SiPS: Workshop on Signal Processing Systems","end_date":"2018-10-24"},"publication_status":"published","year":"2018","language":[{"iso":"eng"}],"user_id":"c635000d-4b10-11ee-a964-aac5a93f6ac1","day":"31","oa_version":"None","month":"12","publication":"2018 IEEE International Workshop on Signal Processing Systems","type":"conference","status":"public","title":"Fast quantized arithmetic on x86: Trading compute for data movement","scopus_import":"1","isi":1,"citation":{"ama":"Stojanov A, Smith TM, Alistarh D-A, Puschel M.

Our algorithm can efficiently solve Boolean CSPs where each variable appears in exactly two constraints (we call it edge CSP) and all constraints are even Δ-matroid relations (represented by lists of tuples). As a consequence of this, we settle the complexity classification of planar Boolean CSPs started by Dvorak and Kupec. Using a reduction to even Δ-matroids, we then extend the tractability result to larger classes of Δ-matroids that we call efficiently coverable. It properly includes classes that were known to be tractable before, namely, co-independent, compact, local, linear, and binary, with the following caveat:We represent Δ-matroids by lists of tuples, while the last two use a representation by matrices. Since an n ×n matrix can represent exponentially many tuples, our tractability result is not strictly stronger than the known algorithm for linear and binary Δ-matroids.","lang":"eng"}],"volume":15,"date_published":"2018-12-01T00:00:00Z","issue":"2","date_created":"2019-02-17T22:59:25Z","project":[{"call_identifier":"FP7","grant_number":"616160","_id":"25FBA906-B435-11E9-9278-68D0E5697425","name":"Discrete Optimization in Computer Vision: Theory and Practice"}],"article_type":"original","scopus_import":"1","publisher":"ACM","main_file_link":[{"open_access":"1","url":"https://arxiv.org/abs/1602.03124"}],"oa":1,"publication_status":"published","date_updated":"2023-09-20T11:20:26Z","oa_version":"Preprint","month":"12","related_material":{"record":[{"status":"public","relation":"earlier_version","id":"1192"}]},"user_id":"c635000d-4b10-11ee-a964-aac5a93f6ac1","article_number":"22","arxiv":1,"quality_controlled":"1","department":[{"_id":"VlKo"}],"doi":"10.1145/3230649","external_id":{"arxiv":["1602.03124"],"isi":["000468036500007"]},"_id":"6032","intvolume":" 15","title":"Even delta-matroids and the complexity of planar boolean CSPs","type":"journal_article","status":"public","article_processing_charge":"No","citation":{"mla":"Kazda, Alexandr, et al. “Even Delta-Matroids and the Complexity of Planar Boolean CSPs.” ACM Transactions on Algorithms, vol. 15, no. 2, 22, ACM, 2018, doi:10.1145/3230649.","apa":"Kazda, A., Kolmogorov, V., & Rolinek, M.

The Fokker-Planck equation is posed on a bounded domain and its transport and diffusion coefficients vanish on the domain's boundary.

We derive the weak formulation of the problem and prove the existence and uniqueness of its solutions by constructing the corresponding contraction semigroup on a suitable function space. Then, we prove that for the parameter regime with high enough mutation rate the problem exhibits a positive spectral gap, which implies exponential convergence to equilibrium.Next, we provide a simple derivation of the so-called Dynamic Maximum Entropy (DynMaxEnt) method for approximation of observables (moments) of the Fokker-Planck solution, which can be interpreted as a nonlinear Galerkin approximation. The limited applicability of the DynMaxEnt method inspires us to introduce its modified version that is valid for the whole range of admissible parameters. Finally, we present several numerical experiments to demonstrate the performance of both the original and modified DynMaxEnt methods. We observe that in the parameter regimes where both methods are valid, the modified one exhibits slightly better approximation properties compared to the original one.","lang":"eng"}],"publication":"Physica D: Nonlinear Phenomena","year":"2018","language":[{"iso":"eng"}],"day":"01","scopus_import":"1","main_file_link":[{"url":"https://arxiv.org/abs/1704.08757","open_access":"1"}],"publisher":"Elsevier","date_created":"2018-12-11T11:47:28Z","arxiv":1,"oa":1,"publication_status":"published","date_updated":"2023-09-19T10:38:34Z","month":"08","oa_version":"Submitted Version","publist_id":"7198","user_id":"c635000d-4b10-11ee-a964-aac5a93f6ac1","title":"Well posedness and maximum entropy approximation for the dynamics of quantitative traits","status":"public","type":"journal_article","article_processing_charge":"No","citation":{"mla":"Bodova, Katarina, et al. “Well Posedness and Maximum Entropy Approximation for the Dynamics of Quantitative Traits.” Physica D: Nonlinear Phenomena, vol. 376–377, Elsevier, 2018, pp. 108–20, doi:10.1016/j.physd.2017.10.015.","apa":"Bodova, K., Haskovec, J., & Markowich, P.

In real life, hardware and software systems are rarely constructed from scratch. Rather, a system is typically constructed from a library of components. Lustig and Vardi formalized this intuition and studied LTL synthesis from component libraries. In real life, designers seek optimal systems. In this paper we add optimality considerations to the setting. We distinguish between quality considerations (for example, size - the smaller a system is, the better it is), and pricing (for example, the payment to the company who manufactured the component). We study the problem of designing systems with minimal quality-cost and price. A key point is that while the quality cost is individual - the choices of a designer are independent of choices made by other designers that use the same library, pricing gives rise to a resource-allocation game - designers that use the same component share its price, with the share being proportional to the number of uses (a component can be used several times in a design). We study both closed and open settings, and in both we solve the problem of finding an optimal design. In a setting with multiple designers, we also study the game-theoretic problems of the induced resource-allocation game.","lang":"eng"}],"volume":712,"author":[{"id":"463C8BC2-F248-11E8-B48F-1D18A9856A87","full_name":"Avni, Guy","orcid":"0000-0001-5588-8287","last_name":"Avni","first_name":"Guy"},{"full_name":"Kupferman, Orna","last_name":"Kupferman","first_name":"Orna"}],"year":"2018","language":[{"iso":"eng"}],"day":"15","publication":"Theoretical Computer Science","ec_funded":1,"isi":1,"citation":{"mla":"Avni, Guy, and Orna Kupferman. “Synthesis from Component Libraries with Costs.” Theoretical Computer Science, vol. 712, Elsevier, 2018, pp. 50–72, doi:10.1016/j.tcs.2017.11.001.","apa":"Avni, G., & Kupferman, O.

They are packaged in specialized secretory organelles called dense core vesicles (DCVs) that are released upon neural stimulation. Unlike synaptic vesicles, which can be recycled and refilled close to release sites, DCVs must be replenished by de novo synthesis in the cell body. Here, we dissect DCV cell biology in vivo in a Caenorhabditis elegans sensory neuron whose tonic activity we can control using a natural stimulus. We express fluorescently tagged neuropeptides in the neuron and define parameters that describe their subcellular distribution. We measure these parameters at high and low neural activity in 187 mutants defective in proteins implicated in membrane traffic, neuroendocrine secretion, and neuronal or synaptic activity. Using unsupervised hierarchical clustering methods, we analyze these data and identify 62 groups of genes with similar mutant phenotypes. We explore the function of a subset of these groups. We recapitulate many previous findings, validating our paradigm. We uncover a large battery of proteins involved in recycling DCV membrane proteins, something hitherto poorly explored. We show that the unfolded protein response promotes DCV production, which may contribute to intertissue communication of stress. We also find evidence that different mechanisms of priming and exocytosis may operate at high and low neural activity. Our work provides a defined framework to study DCV biology at different neural activity levels."}],"date_published":"2018-07-17T00:00:00Z","file_date_updated":"2020-07-14T12:47:19Z","issue":"29","date_created":"2019-03-19T12:41:33Z","file":[{"file_id":"6110","creator":"kschuh","date_created":"2019-03-19T13:01:58Z","checksum":"5e81665377441cdd8d99ab952c534319","relation":"main_file","date_updated":"2020-07-14T12:47:19Z","content_type":"application/pdf","file_name":"2018_PNAS_Laurent.pdf","file_size":1567765,"access_level":"open_access"}],"publisher":"National Academy of Sciences","pmid":1},{"user_id":"3E5EF7F0-F248-11E8-B48F-1D18A9856A87","month":"06","oa_version":"Published Version","date_updated":"2021-01-12T08:06:11Z","ddc":["570"],"publication_identifier":{"issn":["1553-7404"]},"publication_status":"published","oa":1,"has_accepted_license":"1","article_number":"e1007435","_id":"6111","intvolume":" 14","doi":"10.1371/journal.pgen.1007435","external_id":{"pmid":["29879119"]},"quality_controlled":"1","citation":{"ista":"McLachlan IG, Beets I, de Bono M, Heiman MG. 2018.

By studying C. elegans sensory dendrites, we previously identified genes that act to promote the extension of ciliated sensory dendrites during embryogenesis. Interestingly, the nonciliated dendrite of the oxygen-sensing neuron URX is not affected by these genes, suggesting it develops through a distinct mechanism. Here, we use a visual forward genetic screen to identify mutants that affect URX dendrite morphogenesis. We find that disruption of the MAP kinase MAPK-15 or the βH-spectrin SMA-1 causes a phenotype opposite to what we had seen before: dendrites extend normally during embryogenesis but begin to overgrow as the animals reach adulthood, ultimately extending up to 150% of their normal length. SMA-1 is broadly expressed and acts non-cell-autonomously, while MAPK-15 is expressed in many sensory neurons including URX and acts cell-autonomously. MAPK-15 acts at the time of overgrowth, localizes at the dendrite ending, and requires its kinase activity, suggesting it acts locally in time and space to constrain dendrite growth. Finally, we find that the oxygen-sensing guanylate cyclase GCY-35, which normally localizes at the dendrite ending, is localized throughout the overgrown region, and that overgrowth can be suppressed by overexpressing GCY-35 or by genetically mimicking elevated cGMP signaling. These results suggest that overgrowth may correspond to expansion of a sensory compartment at the dendrite ending, reminiscent of the remodeling of sensory cilia or dendritic spines. Thus, in contrast to established pathways that promote dendrite growth during early development, our results reveal a distinct mechanism that constrains dendrite growth throughout the life of the animal, possibly by controlling the size of a sensory compartment at the dendrite ending."}],"volume":14,"date_published":"2018-06-07T00:00:00Z","author":[{"full_name":"McLachlan, Ian G.","last_name":"McLachlan","first_name":"Ian G."},{"full_name":"Beets, Isabel","last_name":"Beets","first_name":"Isabel"},{"orcid":"0000-0001-8347-0443","last_name":"de Bono","first_name":"Mario","full_name":"de Bono, Mario","id":"4E3FF80E-F248-11E8-B48F-1D18A9856A87"},{"last_name":"Heiman","first_name":"Maxwell G.","full_name":"Heiman, Maxwell G."}],"date_created":"2019-03-19T13:09:28Z","publisher":"Public Library of Science","file":[{"date_updated":"2020-07-14T12:47:19Z","content_type":"application/pdf","file_name":"2018_PLOS_McLachlan.pdf","access_level":"open_access","file_size":13011506,"file_id":"6112","date_created":"2019-03-19T13:18:01Z","creator":"kschuh","relation":"main_file","checksum":"622036b945365dbc575bea2768aa9bc8"}],"pmid":1},{"department":[{"_id":"RySh"}],"quality_controlled":"1","_id":"612","page":"1565 - 1587","intvolume":" 223","doi":"10.1007/s00429-017-1568-y","external_id":{"isi":["000428419500030"]},"type":"journal_article","status":"public","pubrep_id":"1013","tmp":{"short":"CC BY (4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","image":"/images/cc_by.png","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)"},"title":"Differential association of GABAB receptors with their effector ion channels in Purkinje cells","isi":1,"article_processing_charge":"No","citation":{"ista":"Luján R, Aguado C, Ciruela F, Cózar J, Kleindienst D, De La Ossa L, Bettler B, Wickman K, Watanabe M, Shigemoto R, Fukazawa Y. 2018.

Here, we analysed the distribution of GABAB receptors using highly sensitive SDS-digested freeze-fracture replica labelling in mouse cerebellar Purkinje cells. Immunoreactivity for GABAB1 was observed on presynaptic and, more abundantly, on postsynaptic compartments, showing both scattered and clustered distribution patterns. Quantitative analysis of immunoparticles revealed a somato-dendritic gradient, with the density of immunoparticles increasing 26-fold from somata to dendritic spines. To understand the spatial relationship of GABAB receptors with two key effector ion channels, the G protein-gated inwardly rectifying K+ (GIRK/Kir3) channel and the voltage-dependent Ca2+ channel, biochemical and immunohistochemical approaches were performed. Co-immunoprecipitation analysis demonstrated that GABAB receptors co-assembled with GIRK and CaV2.1 channels in the cerebellum. Using double-labelling immunoelectron microscopic techniques, co-clustering between GABAB1 and GIRK2 was detected in dendritic spines, whereas they were mainly segregated in the dendritic shafts. In contrast, co-clustering of GABAB1 and CaV2.1 was detected in dendritic shafts but not spines. Presynaptically, although no significant co-clustering of GABAB1 and GIRK2 or CaV2.1 channels was detected, inter-cluster distance for GABAB1 and GIRK2 was significantly smaller in the active zone than in the dendritic shafts, and that for GABAB1 and CaV2.1 was significantly smaller in the active zone than in the dendritic shafts and spines. Thus, GABAB receptors are associated with GIRK and CaV2.1 channels in different subcellular compartments. These data provide a better framework for understanding the different roles played by GABAB receptors and their effector ion channels in the cerebellar network.","lang":"eng"}],"volume":223,"date_published":"2018-04-01T00:00:00Z","author":[{"full_name":"Luján, Rafael","first_name":"Rafael","last_name":"Luján"},{"full_name":"Aguado, Carolina","first_name":"Carolina","last_name":"Aguado"},{"first_name":"Francisco","last_name":"Ciruela","full_name":"Ciruela, Francisco"},{"first_name":"Javier","last_name":"Cózar","full_name":"Cózar, Javier"},{"last_name":"Kleindienst","first_name":"David","id":"42E121A4-F248-11E8-B48F-1D18A9856A87","full_name":"Kleindienst, David"},{"last_name":"De La Ossa","first_name":"Luis","full_name":"De La Ossa, Luis"},{"last_name":"Bettler","first_name":"Bernhard","full_name":"Bettler, Bernhard"},{"full_name":"Wickman, Kevin","last_name":"Wickman","first_name":"Kevin"},{"full_name":"Watanabe, Masahiko","last_name":"Watanabe","first_name":"Masahiko"},{"full_name":"Shigemoto, Ryuichi","id":"499F3ABC-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0001-8761-9444","first_name":"Ryuichi","last_name":"Shigemoto"},{"last_name":"Fukazawa","first_name":"Yugo","full_name":"Fukazawa, Yugo"}],"issue":"3","file_date_updated":"2020-07-14T12:47:20Z"},{"has_accepted_license":"1","article_number":"e32073","oa_version":"Published Version","month":"01","publist_id":"7188","user_id":"c635000d-4b10-11ee-a964-aac5a93f6ac1","related_material":{"record":[{"status":"public","id":"819","relation":"dissertation_contains"}]},"publication_status":"published","oa":1,"date_updated":"2023-09-11T12:54:26Z","ddc":["570","590"],"article_processing_charge":"Yes","citation":{"ama":"Pull C, Ugelvig LV, Wiesenhofer F, et al.

In ants, workers first try to prevent infection of colony members. Here, we show that if this fails and a pathogen establishes an infection, ants employ an efficient multicomponent behaviour − "destructive disinfection" − to prevent further spread of disease through the colony. Ants specifically target infected pupae during the pathogen's non-contagious incubation period, relying on chemical 'sickness cues' emitted by pupae. They then remove the pupal cocoon, perforate its cuticle and administer antimicrobial poison, which enters the body and prevents pathogen replication from the inside out. Like the immune system of a body that specifically targets and eliminates infected cells, this social immunity measure sacrifices infected brood to stop the pathogen completing its lifecycle, thus protecting the rest of the colony. Hence, the same principles of disease defence apply at different levels of biological organisation.","lang":"eng"}],"volume":7,"date_published":"2018-01-09T00:00:00Z","publication":"eLife","day":"09","year":"2018","language":[{"iso":"eng"}],"ec_funded":1,"file":[{"creator":"system","date_created":"2018-12-12T10:10:43Z","checksum":"540f941e8d3530a9441e4affd94f07d7","relation":"main_file","file_id":"4832","file_name":"IST-2018-978-v1+1_elife-32073-v1.pdf","access_level":"open_access","file_size":1435585,"date_updated":"2020-07-14T12:47:20Z","content_type":"application/pdf"}],"publisher":"eLife Sciences Publications","scopus_import":"1","date_created":"2018-12-11T11:47:31Z","project":[{"grant_number":"243071","call_identifier":"FP7","name":"Social Vaccination in Ant Colonies: from Individual Mechanisms to Society Effects","_id":"25DC711C-B435-11E9-9278-68D0E5697425"},{"_id":"25DDF0F0-B435-11E9-9278-68D0E5697425","name":"Pathogen Detectors Collective disease defence and pathogen detection abilities in ant societies: a chemo-neuro-immunological approach","call_identifier":"FP7","grant_number":"302004"}]},{"alternative_title":["LNCS"],"author":[{"first_name":"Girish","last_name":"Koshti","full_name":"Koshti, Girish"},{"id":"3C2B033E-F248-11E8-B48F-1D18A9856A87","full_name":"Biswas, Ranita","orcid":"0000-0002-5372-7890","first_name":"Ranita","last_name":"Biswas"},{"full_name":"Largeteau-Skapin, Gaëlle","first_name":"Gaëlle","last_name":"Largeteau-Skapin"},{"full_name":"Zrour, Rita","last_name":"Zrour","first_name":"Rita"},{"full_name":"Andres, Eric","last_name":"Andres","first_name":"Eric"},{"full_name":"Bhowmick, Partha","first_name":"Partha","last_name":"Bhowmick"}],"date_published":"2018-11-22T00:00:00Z","abstract":[{"text":"In this paper, we propose an algorithm to build discrete spherical shell having integer center and real-valued inner and outer radii on the face-centered cubic (FCC) grid.

Consequently, hosts have evolved resistance and tolerance strategies to suppress or cope with infections. Hosts utilizing resistance improve fitness by clearing or reducing pathogen loads, and hosts utilizing tolerance reduce harmful fitness effects per pathogen load. To understand variation in, and selective pressures on, resistance and tolerance, we asked to what degree they are shaped by host genetic background, whether plasticity in these responses depends upon dietary environment, and whether there are interactions between these two factors. Females from ten wild-type Drosophila melanogaster genotypes were kept on high- or low-protein (yeast) diets and infected with one of two opportunistic bacterial pathogens, Lactococcus lactis or Pseudomonas entomophila. We measured host resistance as the inverse of bacterial load in the early infection phase. The relationship (slope) between fly fecundity and individual-level bacteria load provided our fecundity tolerance measure. Genotype and dietary yeast determined host fecundity and strongly affected survival after infection with pathogenic P. entomophila. There was considerable genetic variation in host resistance, a commonly found phenomenon resulting from for example varying resistance costs or frequency-dependent selection. Despite this variation and the reproductive cost of higher P. entomophila loads, fecundity tolerance did not vary across genotypes. The absence of genetic variation in tolerance may suggest that at this early infection stage, fecundity tolerance is fixed or that any evolved tolerance mechanisms are not expressed under these infection conditions.","lang":"eng"}],"volume":31,"author":[{"first_name":"Megan","last_name":"Kutzer","orcid":"0000-0002-8696-6978","id":"29D0B332-F248-11E8-B48F-1D18A9856A87","full_name":"Kutzer, Megan"},{"first_name":"Joachim","last_name":"Kurtz","full_name":"Kurtz, Joachim"},{"last_name":"Armitage","first_name":"Sophie","full_name":"Armitage, Sophie"}],"year":"2018","language":[{"iso":"eng"}],"day":"01","publication":"Journal of Evolutionary Biology","isi":1,"article_processing_charge":"No","citation":{"chicago":"Kutzer, Megan, Joachim Kurtz, and Sophie Armitage. “Genotype and Diet Affect Resistance, Survival, and Fecundity but Not Fecundity Tolerance.” Journal of Evolutionary Biology.

These hands can easily exploit environmental constraints and object surfaces without risk, and safely interact with humans, but present also some challenges. Designing them is difficult, as well as predicting, modelling, and “programming” their interactions with the objects and the environment. This paper tackles the problem of simulating them in a fast and effective way, leveraging on novel and existing simulation technologies.

Unlike learning methods, our Flexible Learning-free Reconstruction of Imaged Neural volumes (FLoRIN) pipeline exploits structure-specific contextual clues and requires no training. This approach generalizes across different modalities, including serially-sectioned scanning electron microscopy (sSEM) of genetically labeled and contrast enhanced processes, spectral confocal reflectance (SCoRe) microscopy, and high-energy synchrotron X-ray microtomography (μCT) of large tissue volumes. We deploy the FLoRIN pipeline on newly published and novel mouse datasets, demonstrating the high biological fidelity of the pipeline’s reconstructions. FLoRIN reconstructions are of sufficient quality for preliminary biological study, for example examining the distribution and morphology of cells or extracting single axons from functional data.

Accumulating evidence demonstrates a crucial role for phosphatidylinositol-4,5-bisphosphate (PtdIns(4,5)P2) in endocytosis, but specific roles for PtdIns(4)P other than as the biosynthetic precursor of PtdIns(4,5)P2 have not been clarified. In this study we investigated the role of PtdIns(4)P or PtdIns(4,5)P2 in receptor-mediated endocytosis through the construction of temperature-sensitive (ts) mutants for the PI 4-kinases Stt4p and Pik1p and the PtdIns(4) 5-kinase Mss4p. Quantitative analyses of endocytosis revealed that both the stt4(ts)pik1(ts) and mss4(ts) mutants have a severe defect in endocytic internalization. Live-cell imaging of endocytic protein dynamics in stt4(ts)pik1(ts) and mss4(ts) mutants revealed that PtdIns(4)P is required for the recruitment of the alpha-factor receptor Ste2p to clathrin-coated pits whereas PtdIns(4,5)P2 is required for membrane internalization. We also found that the localization to endocytic sites of the ENTH/ANTH domain-bearing clathrin adaptors, Ent1p/Ent2p and Yap1801p/Yap1802p, is significantly impaired in the stt4(ts)pik1(ts) mutant, but not in the mss4(ts) mutant.

To counteract this process, in addition to the discovery and description of resistance mechanisms,a deeper understanding of resistanceevolvabilityand its determinantsis needed. To address this challenge, this thesisuncoversnew genetic determinants of resistance evolvability using a customized robotic setup, exploressystematic ways in which resistance evolution is perturbed due to dose-responsecharacteristics of drugs and mutation rate differences,and mathematically investigates the evolutionary fate of one specific type of evolvability modifier -a stress-induced mutagenesis allele.We find severalgenes which strongly inhibit or potentiate resistance evolution. In order to identify them, we first developedan automated high-throughput feedback-controlled protocol whichkeeps the population size and selection pressure approximately constant for hundreds of cultures by dynamically re-diluting the cultures and adjusting the antibiotic concentration. We implementedthis protocol on a customized liquid handling robot and propagated 100 different gene deletion strains of Escherichia coliin triplicate for over 100 generations in tetracycline and in chloramphenicol, and comparedtheir adaptation rates.We find a diminishing returns pattern, where initially sensitive strains adapted more compared to less sensitive ones. Our data uncover that deletions of certain genes which do not affect mutation rate,including efflux pump components, a chaperone and severalstructural and regulatory genes can strongly and reproducibly alterresistance evolution. Sequencing analysis of evolved populations indicates that epistasis with resistance mutations is the most likelyexplanation. This work could inspire treatment strategies in which targeted inhibitors of evolvability mechanisms will be given alongside antibiotics to slow down resistance evolution and extend theefficacy of antibiotics.We implemented astochasticpopulation genetics model, toverifyways in which general properties, namely, dose-response characteristics of drugs and mutation rates, influence evolutionary dynamics. In particular, under the exposure to antibiotics with shallow dose-response curves,bacteria have narrower distributions of fitness effects of new mutations. We show that in silicothis also leads to slower resistance evolution. We see and confirm with experiments that increased mutation rates, apart from speeding up evolution, also leadto high reproducibility of phenotypic adaptation in a context of continually strong selection pressure.Knowledge of these patterns can aid in predicting the dynamics of antibiotic resistance evolutionand adapting treatment schemes accordingly.Focusing on a previously described type of evolvability modifier –a stress-induced mutagenesis allele –we find conditions under which it can persist in a population under periodic selectionakin to clinical treatment. We set up a deterministic infinite populationcontinuous time model tracking the frequencies of a mutator and resistance allele and evaluate various treatment schemes in how well they maintain a stress-induced mutator allele. In particular,a high diversity of stresses is crucial for the persistence of the mutator allele. This leads to a general trade-off where exactly those diversifying treatment schemes which are likely to decrease levels of resistance could lead to stronger selection of highly evolvable genotypes.In the long run, this work will lead to a deeper understanding of the genetic and cellular mechanisms involved in antibiotic resistance evolution and could inspire new strategies for slowing down its rate.

Proteins from a wide range of non-mammalian species, such as microbial opsins, have been successfully transplanted to specific neuronal targets to override their natural communication patterns. The goal of our work is to manipulate synaptic communication in a manner that closely incorporates the functional intricacies of synapses by preserving temporal encoding (i.e. the firing pattern of the presynaptic neuron) and connectivity (i.e. target specific synapses rather than specific neurons). Our strategy to achieve this goal builds on the use of non-mammalian transplants to create a synthetic synapse. The mode of modulation comes from pre-synaptic uptake of a synthetic neurotransmitter (SN) into synaptic vesicles by means of a genetically targeted transporter selective for the SN. Upon natural vesicular release, exposure of the SN to the synaptic cleft will modify the post-synaptic potential through an orthogonal ligand gated ion channel. To achieve this goal we have functionally characterized a mixed cationic methionine-gated ion channel from Arabidopsis thaliana, designed a method to functionally characterize a synthetic transporter in isolated synaptic vesicles without the need for transgenic animals, identified and extracted multiple prokaryotic uptake systems that are substrate specific for methionine (Met), and established a primary/cell line co-culture system that would allow future combinatorial testing of this orthogonal transmitter-transporter-channel trifecta. Synthetic synapses will provide a unique opportunity to manipulate synaptic communication while maintaining the electrophysiological integrity of the pre-synaptic cell. In this way, information may be preserved that was generated in upstream circuits and that could be essential for concerted function and information processing.
