--- _id: '3725' abstract: - lang: eng text: The combination of high-resolution atomic force microscopy (AFM) imaging and single-molecule force-spectroscopy was employed to unfold single bacteriorhodopsins (BR) from native purple membrane patches at various physiologically relevant temperatures. The unfolding spectra reveal detailed insight into the stability of individual structural elements of BR against mechanical unfolding. Intermittent states in the unfolding process are associated with the stepwise unfolding of alpha-helices, whereas other states are associated with the unfolding of polypeptide loops connecting the alpha-helices. It was found that the unfolding forces of the secondary structures considerably decreased upon increasing the temperature from 8 to 52°C. Associated with this effect, the probability of individual unfolding pathways of BR was significantly influenced by the temperature. At lower temperatures, transmembrane alpha-helices and extracellular polypeptide loops exhibited sufficient stability to individually establish potential barriers against unfolding, whereas they predominantly unfolded collectively at elevated temperatures. This suggests that increasing the temperature decreases the mechanical stability of secondary structural elements and changes molecular interactions between secondary structures, thereby forcing them to act as grouped structures. author: - first_name: Harald L full_name: Harald Janovjak id: 33BA6C30-F248-11E8-B48F-1D18A9856A87 last_name: Janovjak orcid: 0000-0002-8023-9315 - first_name: Max full_name: Kessler, Max last_name: Kessler - first_name: Dieter full_name: Oesterhelt, Dieter last_name: Oesterhelt - first_name: Hermann full_name: Gaub, Hermann last_name: Gaub - first_name: Daniel full_name: Mueller, Daniel J last_name: Mueller citation: ama: Janovjak HL, Kessler M, Oesterhelt D, Gaub H, Mueller D.

To address this question, we developed a fast dynamic-clamp system (approximately 50 kHz) that allowed us to add a Kv3 model conductance to CA1 oriens alveus (OA) interneurons in hippocampal slices. Selective pharmacological block of Kv3 channels by 0.3 mm 4-aminopyridine or 1 mm tetraethylammonium ions led to a marked broadening of APs during trains of short stimuli and a reduction in AP frequency during 1 sec stimuli. The addition of artificial Kv3 conductance restored the original AP pattern. Subtraction of Kv3 conductance by dynamic clamp mimicked the effects of the blockers. Application of artificial Kv3 conductance also led to FS in OA interneurons after complete K+ channel block and even induced FS in hippocampal pyramidal neurons in the absence of blockers. Adding artificial Kv3 conductance with altered deactivation kinetics revealed a nonmonotonic relationship between mean AP frequency and deactivation rate, with a maximum slightly above the original value. Insertion of artificial Kv3 conductance with either lowered activation threshold or inactivation also led to a reduction in the mean AP frequency. However, the mechanisms were distinct. Shifting the activation threshold induced adaptation, whereas adding inactivation caused frequency-dependent AP broadening. In conclusion, Kv3 channels are necessary for the FS phenotype of OA interneurons, and several of their gating properties appear to be optimized for high-frequency repetitive activity. author: - first_name: Cheng full_name: Lien, Cheng-Chang last_name: Lien - first_name: Peter M full_name: Peter Jonas id: 353C1B58-F248-11E8-B48F-1D18A9856A87 last_name: Jonas orcid: 0000-0001-5001-4804 citation: ama: Lien C, Jonas PM.

Evaluation of different methods by using a morphology-based equivalent electrical model revealed that quantitative capacitance measurements are possible in this presynaptic structure. Voltage pulses leading to presynaptic Ca2+ inflow evoked large capacitance signals that showed saturation with increasing pulse duration. The mean peak capacitance increase was 100 fF, corresponding to a pool of approximately 1,400 releasable vesicles. Thus hippocampal mossy fiber synapses have a vesicular "maxipool." Large pool size and rapid vesicle recycling may underlie the uniquely large extent of activity-dependent plasticity in this synapse. author: - first_name: Stefan full_name: Hallermann, Stefan last_name: Hallermann - first_name: Christian full_name: Pawlu, Christian last_name: Pawlu - first_name: Peter M full_name: Peter Jonas id: 353C1B58-F248-11E8-B48F-1D18A9856A87 last_name: Jonas orcid: 0000-0001-5001-4804 - first_name: Manfred full_name: Heckmann, Manfred last_name: Heckmann citation: ama: Hallermann S, Pawlu C, Jonas PM, Heckmann M.

Whereas ergatoid males are highly intolerant of each other and fight among themselves, they tend to tolerate their winged counterparts. This is despite the fact that these winged males, like ergatoid males, represent mating competition. Why should ergatoid males tolerate their winged rivals? We developed a mathematical model to address this question. Our model focuses on a number of factors likely toinfluence whether ergatoid males are tolerant of winged males: ergatoid male–winged male relatedness, number of virgin queens, number of winged males, and the number of ejaculates a winged male has (winged males are sperm limited, whereas ergatoid males have lifelong spermatogenesis). Surprisingly, we found that increasing the number of virgin queens favors a kill strategy, whereas an increase in the other factors favors a let-live strategy; these predictions appear true for C. obscurior and for a number of other Cardiocondyla species. Two further aspects, unequal insemination success and multiple mating in queens, were also incorporated into the model and predictions made about their effects on toleration of winged males. The model is applicable more generally in species that have dimorphic males, such as some other ants, bees, and fig wasps.' author: - first_name: Carl full_name: Anderson, Carl last_name: Anderson - first_name: Sylvia full_name: Cremer, Sylvia id: 2F64EC8C-F248-11E8-B48F-1D18A9856A87 last_name: Cremer orcid: 0000-0002-2193-3868 - first_name: Jürgen full_name: Heinze, Jürgen last_name: Heinze citation: ama: 'Anderson C, Cremer S, Heinze J.

Due to these counteracting selection pressures, many species evolved dispersal polymorphisms, which, in ants, are typically restricted to the female sex (queens). Male polymorphism is presently only known from a few genera, such as Cardiocondyla, in which winged dispersing males coexist with wingless fighter males that mate exclusively inside their maternal nests. We studied the developmental mechanisms underlying these alternative male morphs and found that, first, male dimorphism is not genetically determined, but is induced by environmental conditions (decreasing temperature and density). Second, male morph is not yet fixed at the egg stage, but it differentiates during larval development. This flexible developmental pattern of male morphs allows Cardiocondyla ant colonies to react quickly to changes in their environment. Under good conditions, they invest exclusively in philopatric wingless males. But, when environmental conditions turn bad, colonies start to produce winged dispersal males, even though these males require a many times higher investment by the colony than their much smaller wingless counterparts. Cardiocondyla ants share this potential of optimal resource allocation with other colonial animals and some seed dimorphic plants. author: - first_name: Sylvia full_name: Cremer, Sylvia id: 2F64EC8C-F248-11E8-B48F-1D18A9856A87 last_name: Cremer orcid: 0000-0002-2193-3868 - first_name: Jürgen full_name: Heinze, Jürgen last_name: Heinze citation: ama: 'Cremer S, Heinze J.

In formal verification, the designer describes the system in a modeling language with a well-defined semantics, and this system description is analyzed against a set of correctness requirements. Model checking is an algorithmic technique to check that a system description indeed satisfies correctness requirements given as logical specifications. While successful in hardware verification, the potential for model checking for software and embedded systems has not yet been realized. This is because traditional model checking focuses on systems modeled as finite state-transition graphs. While a natural model for hardware (especially synchronous hardware), state-transition graphs often do not capture software and embedded systems at an appropriate level of granularity. This dissertation considers two orthogonal extensions to finite state-transition graphs making model checking techniques applicable to both a wider class of systems and a wider class of properties.\r\n\r\nThe first direction is an extension to infinite-state structures finitely represented using constraints and operations on constraints. Infinite state arises when we wish to model variables with unbounded range (e.g., integers), or data structures, or real time. We provide a uniform framework of symbolic region algebras to study model checking of infinite-state systems. We also provide sufficient language-independent termination conditions for symbolic model checking algorithms on infinite state systems.\r\n\r\nThe second direction supplements verification with game theoretic reasoning. Games are natural models for interactions between components. We study game theoretic behavior with winning conditions given by temporal logic objectives both in the deterministic and in the probabilistic context. For deterministic games, we provide an extremal model characterization of fixpoint algorithms that link solutions of verification problems to solutions for games. For probabilistic games we study fixpoint characterization of winning probabilities for games with omega-regular winning objectives, and construct (epsilon-)optimal winning strategies." article_processing_charge: No author: - first_name: Ritankar full_name: Majumdar, Ritankar last_name: Majumdar citation: ama: Majumdar R.

Giotto’s precise semantics and predictabil- ity make it suitable for safety-critical applications.\r\nGiotto is based around the idea that time-triggered task invocation together with time-triggered mode switching can form a useful programming model for real-time systems. To substantiate this claim, we describe the use of Giotto to refactor the software of a small, autonomous helicopter. The ease with which Giotto expresses the existing software provides evidence that Giotto is an appropriate programming language for control systems.\r\nSince Giotto is a real-time programming language, ensuring that Giotto programs meet their deadlines is crucial. To study precedence-constrained Giotto scheduling, we first examine single-mode, single-processor scheduling. We extend to an infinite, periodic setting the classical problem of meeting deadlines for a set of tasks with release times, deadlines, precedence constraints, and preemption. We then develop an algorithm for scheduling Giotto programs on a single processor by representing Giotto programs as instances of the extended scheduling problem.\r\nNext, we study multi-mode, single-processor Giotto scheduling. This problem is different from classical scheduling problems, since in our precedence-constrained approach, the deadlines of tasks may vary depending on the mode switching behavior of the program. We present conditional scheduling models which capture this varying-deadline behavior. We develop polynomial-time algorithms for some conditional scheduling models, and prove oth- ers to be computationally hard. We show how to represent multi-mode Giotto programs as instances of the model, resulting in an algorithm for scheduling multi-mode Giotto programs on a single processor.\r\nFinally, we show that the problem of scheduling Giotto programs for multiple net- worked processors is strongly NP-hard." article_processing_charge: No author: - first_name: Benjamin full_name: Horowitz, Benjamin last_name: Horowitz citation: ama: 'Horowitz B.

In the case of a radial expansion holding the axial confinement fixed we consider various models for the interactions, depending on the thickness of the condensate relative to the value of the scattering length. We are thus able to evaluate different scattering regimes ranging from quasi-three-dimensional (Q3D) to strictly two-dimensional (2D). We find that as the system goes from Q3D to 2D the expansion rate of the condensate increases whereas that of the vortex core decreases. In the Q3D scattering regime we also examine a fully free expansion in 3D and find oscillatory behaviour for the vortex core radius: an initial fast expansion of the vortex core is followed by a slowing down. Such a nonuniform expansion rate of the vortex core implies that the timing of its observation should be chosen appropriately.' author: - first_name: Onur full_name: Onur Hosten id: 4C02D85E-F248-11E8-B48F-1D18A9856A87 last_name: Hosten orcid: 0000-0002-2031-204X - first_name: Patrizia full_name: Vignolo, Patrizia last_name: Vignolo - first_name: Anna full_name: Minguzzi, Anna last_name: Minguzzi - first_name: Bilal full_name: Tanatar, Bilal last_name: Tanatar - first_name: Mario full_name: Tosi, Mario P last_name: Tosi citation: ama: 'Hosten O, Vignolo P, Minguzzi A, Tanatar B, Tosi M.

Here we identify FMRFamide-related neuropeptides (FaRPs) encoded by the flp-18 and flp-21 genes as NPR-1 ligands and show that these peptides can differentially activate the NPR-1 215F and NPR-1 215V receptors. Multicopy overexpression of flp-21 transformed wild social animals into solitary feeders. Conversely, a flp-21 deletion partially phenocopied the npr-1(null) phenotype, which is consistent with NPR-1 activation by FLP-21 in vivo but also implicates other ligands for NPR-1. Phylogenetic studies indicate that the dominant npr-1 215V allele likely arose from an ancestral npr-1 215F gene in C. elegans.

Previous studies have shown that history of recombination events has produced long haplotype blocks in the human genome, which contribute to this heterogeneity. Other factors, however, such as natural selection or the heterogeneity of mutation rates across loci, may also lead to heterogeneity of genetic variability. We compared synonymous and non-synonymous variability within human genes with their divergence from murine orthologs. We separately analyzed the non-synonymous variants predicted to damage protein structure or function and the variants predicted to be functionally benign. The predictions were based on comparative sequence analysis and, in some cases, on the analysis of protein structure. A strong correlation between non-synonymous, benign variability and non-synonymous human-mouse divergence suggests that selection played an important role in shaping the pattern of variability in coding regions of human genes. However, the lack of correlation between deleterious variability and evolutionary divergence shows that a substantial proportion of the observed non-synonymous single-nucleotide polymorphisms reduces fitness and never reaches fixation. Evolutionary and medical implications of the impact of selection on human polymorphisms are discussed. acknowledgement: We are grateful to Alexey Kondrashov and Alison Wellman for the careful reading of the manuscript and providing us with their valuable comments. author: - first_name: Shamil full_name: Sunyaev, Shamil R last_name: Sunyaev - first_name: Fyodor full_name: Fyodor Kondrashov id: 44FDEF62-F248-11E8-B48F-1D18A9856A87 last_name: Kondrashov orcid: 0000-0001-8243-4694 - first_name: Peer full_name: Bork, Peer last_name: Bork - first_name: Vasily full_name: Ramensky, Vasily last_name: Ramensky citation: ama: Sunyaev S, Kondrashov F, Bork P, Ramensky V.

We analyzed the evolutionary conservation of proteins encoded by alternatively spliced genes and predicted the ancestral state for 73 cases of alternative splicing (25 insertions and 48 deletions). The amino acid sequences of most of the inserts in proteins produced by alternative splicing are as conserved as the surrounding sequences. Thus, alternative splicing often creates novel isoforms by the insertion of new, functional protein sequences that probably originated from noncoding sequences of introns. acknowledgement: We thank Peer Bork, Mikhail Gelfand, Alexey Kondrashov, David Lipman and Shamil Sunyaev for critical reading of the manuscript and useful suggestions and the Koonin group members for helpful discussions. author: - first_name: Fyodor full_name: Fyodor Kondrashov id: 44FDEF62-F248-11E8-B48F-1D18A9856A87 last_name: Kondrashov orcid: 0000-0001-8243-4694 - first_name: Eugene full_name: Koonin, Eugene V last_name: Koonin citation: ama: 'Kondrashov F, Koonin E.

In addition, plants display a phenomenon termed RNA-directed DNA methylation (RdDM) in which DNA with sequence identity to silenced RNA is de novo methylated at its cytosine residues. This methylation is not only at canonical CpG sites but also at cytosines in CpNpG and asymmetric sequence contexts. In this report, we study the role of the DRM and CMT3 DNA methyltransferase genes in the initiation and maintenance of RdDM. Neither drm nor cmt3 mutants affected the maintenance of preestablished RNA-directed CpG methylation. However, drm mutants showed a nearly complete loss of asymmetric methylation and a partial loss of CpNpG methylation. The remaining asymmetric and CpNpG methylation was dependent on the activity of CMT3, showing that DRM and CMT3 act redundantly to maintain non-CpG methylation. These DNA methyltransferases appear to act downstream of siRNAs, since drm1 drm2 cmt3 triple mutants show a lack of non-CpG methylation but elevated levels of siRNAs. Finally, we demonstrate that DRM activity is required for the initial establishment of RdDM in all sequence contexts including CpG, CpNpG, and asymmetric sites. article_processing_charge: No article_type: original author: - first_name: Xiaofeng full_name: Cao, Xiaofeng last_name: Cao - first_name: Werner full_name: Aufsatz, Werner last_name: Aufsatz - first_name: Daniel full_name: Zilberman, Daniel id: 6973db13-dd5f-11ea-814e-b3e5455e9ed1 last_name: Zilberman orcid: 0000-0002-0123-8649 - first_name: M.Florian full_name: Mette, M.Florian last_name: Mette - first_name: Michael S. full_name: Huang, Michael S. last_name: Huang - first_name: Marjori full_name: Matzke, Marjori last_name: Matzke - first_name: Steven E. full_name: Jacobsen, Steven E. last_name: Jacobsen citation: ama: Cao X, Aufsatz W, Zilberman D, et al.

We cloned ARGONAUTE4 (AGO4) from a screen for mutants that suppress silencing of the Arabidopsis SUPERMAN(SUP) gene. The ago4-1 mutant reactivated silentSUP alleles and decreased CpNpG and asymmetric DNA methylation as well as histone H3 lysine-9 methylation. In addition,ago4-1 blocked histone and DNA methylation and the accumulation of 25-nucleotide small interfering RNAs (siRNAs) that correspond to the retroelement AtSN1. These results suggest that AGO4 and long siRNAs direct chromatin modifications, including histone methylation and non-CpG DNA methylation. article_processing_charge: No article_type: original author: - first_name: Daniel full_name: Zilberman, Daniel id: 6973db13-dd5f-11ea-814e-b3e5455e9ed1 last_name: Zilberman orcid: 0000-0002-0123-8649 - first_name: ' Xiaofeng' full_name: Cao, Xiaofeng last_name: Cao - first_name: Steven E. full_name: Jacobsen, Steven E. last_name: Jacobsen citation: ama: Zilberman D, Cao Xiaofeng, Jacobsen SE.

Discounting (or inflation) is a key paradigm in economics and has been studied in Markov decision processes as well as game theory. We submit that discounting also has a natural place in systems engineering: for nonterminating systems, a potential bug in the far-away future is less troubling than a potential bug today. We therefore develop a systems theory with discounting. Our theory includes several basic elements: discounted versions of system properties that correspond to the ω-regular properties, fixpoint-based algorithms for checking discounted properties, and a quantitative notion of bisimilarity for capturing the difference between two states with respect to discounted properties. We present the theory in a general form that applies to probabilistic systems as well as multicomponent systems (games), but it readily specializes to classical transition systems. We show that discounting, besides its natural practical appeal, has also several mathematical benefits. First, the resulting theory is robust, in that small perturbations of a system can cause only small changes in the properties of the system. Second, the theory is computational, in that the values of discounted properties, as well as the discounted bisimilarity distance between states, can be computed to any desired degree of precision.' acknowledgement: This research was supported in part by the NSF CAREER award CCR-0132780, the DARPA grant F33615-C-98-3614, the NSF grants CCR-9988172, CCR-0234690 and CCR-0225610, and the ONR grant N00014-02-1-0671. alternative_title: - LNCS article_processing_charge: No author: - first_name: Luca full_name: De Alfaro, Luca last_name: De Alfaro - first_name: Thomas A full_name: Henzinger, Thomas A id: 40876CD8-F248-11E8-B48F-1D18A9856A87 last_name: Henzinger orcid: 0000−0002−2985−7724 - first_name: Ritankar full_name: Majumdar, Ritankar last_name: Majumdar citation: ama: 'De Alfaro L, Henzinger TA, Majumdar R.

The formalism permits an algorithmic check if two or more components, when put together, exceed the available resources. Moreover, the formalism can be used to compute the quantity of resources necessary for satisfying the requirements of a collection of components. The formalism can be instantiated in several ways. For example, several components may draw power from the same source. Then, the formalism supports compatibility checks such as: can two components, when put together, achieve their tasks without ever exceeding the available amount of peak power? or, can they achieve their tasks by using no more than the initially available amount of energy (i.e., power accumulated over time)? The corresponding quantitative questions that our algorithms answer are the following: what is the amount of peak power needed for two components to be put together? what is the corresponding amount of initial energy? To solve these questions, we model interfaces with resource requirements as games with quantitative objectives. The games are played on state spaces where each state is labeled by a number (representing, e.g., power consumption), and a play produces an infinite path of labels. The objective may be, for example, to minimize the largest label that occurs during a play. We illustrate our approach by modeling compatibility questions for the components of robot control software, and of wireless sensor networks.' acknowledgement: This research was supported in part by the DARPA grant F33615-00-C-1693, the MARCO grant 98-DT-660, the ONR grant N00014-02-1-0671, and the NSF grants CCR-0085949, CCR-0132780, CCR-0234690, and CCR-9988172. alternative_title: - LNCS article_processing_charge: No author: - first_name: Arindam full_name: Chakrabarti, Arindam last_name: Chakrabarti - first_name: Luca full_name: De Alfaro, Luca last_name: De Alfaro - first_name: Thomas A full_name: Henzinger, Thomas A id: 40876CD8-F248-11E8-B48F-1D18A9856A87 last_name: Henzinger orcid: 0000−0002−2985−7724 - first_name: Mariëlle full_name: Stoelinga, Mariëlle last_name: Stoelinga citation: ama: 'Chakrabarti A, De Alfaro L, Henzinger TA, Stoelinga M.

Such timed games differ from untimed games in two essential ways. First, players can take each other by surprise, because actions are played with delays that cannot be anticipated by the opponent. Second, a player should not be able to win the game by preventing time from diverging. We present a model of timed games that preserves the element of surprise and accounts for time divergence in a way that treats both players symmetrically and applies to all ω-regular winning conditions. We prove that the ability to take each other by surprise adds extra power to the players. For the case that the games are specified in the style of timed automata, we provide symbolic algorithms for their solution with respect to all ω-regular winning conditions. We also show that for these timed games, memory strategies are more powerful than memoryless strategies already in the case of reachability objectives. acknowledgement: Supported in part by the AFOSR MURI grant F49620-00-1-0327, the DARPA grant F33615-C-98-3614, the MARCO grant 98-DT-660, -the ONR grant N00014-02-1-0671, the NSF grants CCR-9988172, CCR-0225610, and CCR-0234690, the NSF CAREER award CCR-0132780, and the MIUR grant MEFISTO. alternative_title: - LNCS article_processing_charge: No author: - first_name: Luca full_name: De Alfaro, Luca last_name: De Alfaro - first_name: Marco full_name: Faella, Marco last_name: Faella - first_name: Thomas A full_name: Henzinger, Thomas A id: 40876CD8-F248-11E8-B48F-1D18A9856A87 last_name: Henzinger orcid: 0000−0002−2985−7724 - first_name: Ritankar full_name: Majumdar, Ritankar last_name: Majumdar - first_name: Mariëlle full_name: Stoelinga, Mariëlle last_name: Stoelinga citation: ama: 'De Alfaro L, Faella M, Henzinger TA, Majumdar R, Stoelinga M.
