description: Organic-inorganic hybrid halide perovskites, in which the A cations of an ABX$_3$ perovskite are replaced by organic cations, may be used for photovoltaic and solar thermoelectric applications. In this contribution, we systematically study three lead-free hybrid perovskites, i.e., methylammonium tin iodide CH$_3$NH$_3$SnI$_3$, ammonium tin iodide NH$_4$SnI$_3$, and formamidnium tin iodide HC(NH$_2$)$_2$SnI$_3$, by first-principles calculations. We find that in addition to the commonly known motif in which the corner-shared SnI$_6$ octahedra form a three-dimensional network, these materials may also favor a two-dimensional (layered) motif formed by alternating layers of the SnI$_6$ octahedra and the organic cations. These two motifs are nearly equal in free energy and are separated by low barriers. These layered structures features many flat electronic bands near the band edges, making their electronic structures significantly different from those of the structural phases composed of three-dimension networks of SnI$_6$ octahedra. Furthermore, because the electronic structures of HC(NH$_2$)$_2$SnI$_3$ are found to be rather similar to those of CH$_3$NH$_3$SnI$_3$, formamidnium tin iodide may also be promising for the applications of methylammonium tin iodide.

description: Abstract: "The XWand is a wireless UI device that enables styles of natural interaction with intelligent environments. The XWand system exploits human intuition, allowing control of everyday objects through pointing and gesturing. We describe the hardware device and then examine several approaches to gesture recognition. We discuss results from experiments using a linear time warping method, a dynamic time warping (DTW) method, and a hidden Markov model-based method (HMM)."

description: We consider finite 2-complexes X that arise as quotients of Fuchsian buildings by subgroups of the combinatorial automorphism group, which we assume act freely and cocompactly. We show that locally CAT(-1) metrics on X which are piecewise hyperbolic and satisfy a natural non-singularity condition at vertices are marked length spectrum rigid within certain classes of negatively curved, piecewise Riemannian metrics on X. As a key step in our proof, we show that the marked length spectrum function for such metrics determines the volume of X.

description: We investigate the correlation between extinction and H~{\sc i} and CO emission at intermediate and high Galactic latitudes ($|b|>10\degr$) within the footprint of the Xuyi Schmidt Telescope Photometric Survey of the Galactic anticentre (XSTPS-GAC) on small and large scales. In Paper I (Chen et al. 2014), we present a three-dimensional dust extinction map within the footprint of XSTPS-GAC, covering a sky area of over 6,000\,deg$^2$ at a spatial angular resolution of 6\,arcmin. In the current work, the map is combined with data from gas tracers, including H~{\sc i} data from the Galactic Arecibo L-band Feed Array H~{\sc i} survey and CO data from the Planck mission, to constrain the values of dust-to-gas ratio $DGR=A_V/N({\rm H})$ and CO-to-$\rm H_2$ conversion factor $X_{\rm CO}=N({\rm H_2})/W_{\rm CO}$ for the entire GAC footprint excluding the Galactic plane, as well as for selected star-forming regions (such as the Orion, Taurus and Perseus clouds) and a region of diffuse gas in the northern Galactic hemisphere. For the whole GAC footprint, we find $DGR=(4.15\pm0.01) \times 10^{-22}$\,$\rm mag\,cm^{2}$ and $X_{\rm CO}=(1.72 \pm 0.03) \times 10^{20}$\,$\rm cm^{-2}\,(K\,km\,s^{-1})^{-1}$. We have also investigated the distribution of "CO-dark" gas (DG) within the footprint of GAC and found a linear correlation between the DG column density and the $V$-band extinction: $N({\rm DG}) \simeq 2.2 \times 10^{21} (A_V - A^{c}_{V})\,\rm cm^{-2}$. The mass fraction of DG is found to be $f_{\rm DG}\sim 0.55$ toward the Galactic anticentre, which is respectively about 23 and 124 per cent of the atomic and CO-traced molecular gas in the same region. This result is consistent with the theoretical work of Papadopoulos et al. but much larger than that expected in the $\rm H_2$ cloud models by Wolfire et al.

description: In the circuit quantum electrodynamics architecture, both the resonance frequency and the coupling of superconducting qubits to microwave field modes can be controlled via external electric and magnetic fields to explore qubit -- photon dynamics in a wide parameter range. Here, we experimentally demonstrate and analyze a scheme for tuning the coupling between a transmon qubit and a microwave resonator using a single coherent drive tone. We treat the transmon as a three-level system with the qubit subspace defined by the ground and the second excited states. If the drive frequency matches the difference between the resonator and the qubit frequency, a Jaynes-Cummings type interaction is induced, which is tunable both in amplitude and phase. We show that coupling strengths of about 10 MHz can be achieved in our setup, limited only by the anharmonicity of the transmon qubit. This scheme has been successfully used to generate microwave photons with controlled temporal shape [Pechal et al., Phys. Rev. X 4, 041010 (2014)] and can be directly implemented with superconducting quantum devices featuring larger anharmonicity for higher coupling strengths.

description: Der Beitrag beleuchtet die soziale, gesellschaftliche und demografische Situation von Frauen in Österreich und stellt diese in Bezug zu Wohnen. Die Wohnbaupolitik in Österreich sowie die Zugänglichkeit und Leistbarkeit von öffentlich gefördertem Wohnbau und privaten Mietwohnungsmarkt wird beschrieben. Der Wiener Wohnbau hat Qualiätsstandards, die in engem Zusammenhang mit Gender Planning stehen. Ein historischer Überblick zeigt Wohnreformmodelle und und Modellwohnprojekte, die von Frauen entwickelt wurden für eine verbesserte Alltagstauglichkeit und Leistbarkeit. Abschliessend werden Empfehlungen abgegeben, um die Mitbestimmung und Vertretung von Frauen-Anliegen im Wohnbau zu erhöhen, den Zugang zum sozialen Wohnbau zu erleichtern, leistbarerere Finanzierungsmodelle einzuführen, die Schnittstelle Frauenpolitik und Wohnungspolitik zu stärken sowie der Quartiersplanung eine höhrere Bedeutung zukommen zu lassen.
description: Frauenpolitische Forderungen nach Gleichstellung und Chancengleichheit sind im Sektor Wohnbau und Wohnbaupolitik noch weitgehend unterrepräsentiert. Frauen verdienen nach wie vor um ein Viertel weniger als Männer, Alterspensionen der Männer sind um fast zwei Drittel höher als jene der Frauen und Frauen sind wesentlich häufiger Armutsgefährdet. Damit wird Leistbarkeit von Wohnraum zu einem spezifischen frauenpolitischen Thema. Die hohe Armuts- und Ausgrenzungsgefährdung von Frauen ist ein wichtiger Aspekt, dem sich auch Wohnbaupolitik zu widmen sollte.

description: Sodium-glucose co-transporter-2 inhibitors are used in the treatment of diabetes but are also emerging as cardioprotective agents in heart diseases even in the absence of type 2 diabetes. In this paper, upon providing a short overview of common pathophysiological features of diabetes, we review the clinically reported cardio- and nephroprotective potential of sodium-glucose co-transporter-2 inhibitors currently available on the market, including Dapagliflozin, Canagliflozin, and Empagliflozin. To that end, we summarize findings of clinical trials that have initially drawn attention to the drugs' organ-protective potential, before providing an overview of their proposed mechanism of action. Since we particularly expect that their antioxidative properties will broaden the application of gliflozins from therapeutic to preventive care, special emphasis was put on this aspect.

description: Selective data return leverages onboard data analysis to allocate limited bandwidth resources during remote exploration. Here we present an adaptive method to subsample image sequences for downlink. We treat selective data return as a compression problem in which the explorer agent transmits the subset of measurements that are most informative with respect to the complete dataset. Experiments demonstrate selective downlink of navigation imagery by a rover during autonomous geologic investigations in the Atacama desert of Chile. Here automatic analysis identifies informative images using classifications based on natural image statistics. Image texture analysis, together with a context-sensitive Hidden Markov Model representation, permits adaptive downlink in response to geologic unit boundaries. Selective data return improves the science content of returned data for this geologic mapping task.

description: We revise the classical problem of characterizing first exit times of a harmonically trapped particle whose motion is described by one- or multi-dimensional Ornstein-Uhlenbeck process. We start by recalling the main derivation steps of a propagator using Langevin and Fokker-Planck equations. The mean exit time, the moment-generating function, and the survival probability are then expressed through confluent hypergeometric functions and thoroughly analyzed. We also present a rapidly converging series representation of confluent hypergeometric functions that is particularly well suited for numerical computation of eigenvalues and eigenfunctions of the governing Fokker-Planck operator. We discuss several applications of first exit times such as detection of time intervals during which motor proteins exert a constant force onto a tracer in optical tweezers single-particle tracking experiments; adhesion bond dissociation under mechanical stress; characterization of active periods of trend following and mean-reverting strategies in algorithmic trading on stock markets; relation to the distribution of first crossing times of a moving boundary by Brownian motion. Some extensions are described, including diffusion under quadratic double-well potential and anomalous diffusion.

HYBRID PROPULSION

description: Hybrid Rocket Engines (HREs) could replace existing bipropellant liquid engines for some specific applications such as small launchers at low cost or orbital insertion of multiple payloads in different orbits as HREs offer much lower costs and large throttle ability. Drawbacks are related to the difficulty to control the oxidizer-to-fuel (O/F) ratio during operation, the low regression rate of the solid fuel grain, and the residual inert mass. The use of paraffin-based fuel can overcome part of the problem of the low regression rate of the solid fuel. Tests carried out over the last decade indicate that the pure paraffin regression rate is from three to four times larger than traditional hybrid rocket fuels such as Hydroxyl-Terminated Polybutadiene (HTPB) [1]. However, pure paraffin has poor structural characteristics and sometimes low performance due to the fuel internal ballistics behaviour. The fact that the fuel is in the solid phase makes it very easy to add solid performance-enhancing materials that may enable hybrid rocket engines to gain specific impulse and specific mass advantage in comparison with hydrocarbon-fuel liquid. Additionally, metal additives can be used to reduce the O/F ratio for maximum specific impulse, thereby enabling a reduction in the required mass of liquid oxidizer [2]. Previous studies carried out by the Aero-Thermo-Mechanics Laboratory (ATM) at Universite Libre de Bruxelles and Belgium Royal Military academy (RMA) indicate that, in some conditions, Magnesium Diboride, MgB2, is a candidate for paraffin-based fuels performance enhancement. The main advantage of using the Magnesium Diboride lies in the fact that this additive is much more stable and easier to handle than others metal hydrides, as LAH (Lithium Aluminium Hydride) and MgH2 (Magnesium Diboride). The tests using the 2-D RMA Hybrid Rocket were done at low oxidizer mass flow rate and chamber pressure, from 1.1 to 5.5 bar [3], and burning times from 1.1 to 5.5 seconds. This study presents the results of a series of experimental investigations using the 1kN hybrid rocket engine at higher oxidizer mass flow rate and chamber pressure, and the average burning time also was an increase. These conditions are more representative of hybrid rocket real applications, mainly the level of the combustion chamber pressure.

description: We show that the tropicalization of a connected variety over a higher rank valued field is a path connected topological space. This establishes an affirmative answer to a question posed by Banerjee. Higher rank tropical varieties are studied as the images of "Hahn analytifications", introduced in this paper. A Hahn analytification is a space of valuations on a scheme over a higher rank valued field. We prove that the Hahn analytification is related to higher rank tropicalization by means of an inverse limit theorem, extending well-known results in the non-Archimedean case. We also establish comparison results between the Hahn analytification and the Huber and Berkovich analytifications, as well as the Hrushovski-Loeser stable completion.

Scaling Symmetries and Parameter Reduction in Epidemic SI(R)S Models

description: Symmetry concepts in parametrized dynamical systems may reduce the number of external parameters by a suitable normalization prescription. If, under the action of a symmetry group G , parameter space A becomes a (locally) trivial principal bundle, A ≅ A / G × G , then the normalized dynamics only depends on the quotient A / G . In this way, the dynamics of fractional variables in homogeneous epidemic SI(R)S models, with standard incidence, absence of R-susceptibility and compartment independent birth and death rates, turns out to be isomorphic to (a marginally extended version of) Hethcote’s classic endemic model, first presented in 1973. The paper studies a 10-parameter master model with constant and I-linear vaccination rates, vertical transmission and a vaccination rate for susceptible newborns. As recently shown by the author, all demographic parameters are redundant. After adjusting time scale, the remaining 5-parameter model admits a 3-dimensional abelian scaling symmetry. By normalization we end up with Hethcote’s extended 2-parameter model. Thus, in view of symmetry concepts, reproving theorems on endemic bifurcation and stability in such models becomes needless.
Making Logistic Regression A Core Data Mining Tool

description: Binary classification is a core data mining task. For large datasets or real-time applications, desirable classifiers are
accurate, fast, and automatic (i.e. no parameter tuning). Naive Bayes and decision trees are fast and parameter-free, but
their accuracy is often below state-of-the-art. Linear support vector machines (SVM) are fast and have good accuracy,
but current implementations are sensitive to the capacity parameter. SVMs with radial basis function kernels are accurate
but slow, and have multiple parameters that require tuning.

In this paper we demonstrate that a very simple parameter-free implementation of logistic regression (LR) is sufficiently
accurate and fast to compete with state-of-the-art binary classifiers on large real-world datasets. The accuracy is
comparable to per-dataset tuned linear SVMs and, in higher dimensions, to tuned RBF SVMs. A combination of regularization,
truncated-Newton methods, and iteratively re-weighted least squares make this implementation faster than
SVMs and relatively insensitive to parameters. Our fitting procedure, TR-IRLS, appears to outperform several common
LR fitting procedures in our experiments. TR-IRLS is robust to linear dependencies and scaling problems in the data,
and no data preprocessing is necessary. TR-IRLS is easy to implement and can be used anywhere that IRLS is used.
Convergence guarantees can be stated for generalized linear models with canonical links.

description: A key factor in the prevention of hair loss is the provision of optimal conditions on the scalp. In this regard, reduction of oxidative stress on the scalp is one critical requirement to support the hair follicles to function optimally. Recently, a novel shampoo formulation technology containing anti-oxidants such as piroctone olamine has been demonstrated to improve hair retention based on micellar degradation and coacervation effects. Caffeine has also been shown to exhibit anti-oxidant activity including the ability to inhibit lipid peroxidation. As with piroctone olamine, it is expected that follicular delivery of caffeine will enhance its anti-oxidant activity in a region that will be beneficial for hair retention. In this study, two shampoo formulations as well as a control formulation were applied to the calf area of n = 9 male participants. The technique of differential tape stripping was applied to obtain the caffeine penetrated to the stratum corneum and to the hair follicles. Isotope-dilution liquid chromatography coupled with tandem mass spectrometry (LC-MS/MS) was performed to demonstrate caffeine follicular delivery from the shampoo formulas. The results showed that the percentage of caffeine recovered in the hair follicles was 8–9% of the caffeine absorbed into the skin and matched an existing caffeine-based shampoo. In conclusion, a novel shampoo formulation technology has been developed that effectively delivers beneficial anti-oxidants to improve hair retention. This new shampoo is expected to be especially useful in the goal of retaining hair during aging.

description: The NURI, commonly known as Korea Space Launch Vehicle-II(KSLV-II), is a three-stage launch vehicle developed by Korea Aerospace Research Institute(KARI). The KSLV-II can put a 1.5 ton-class practical satellite into the low earth orbit(600~800km). All three stages have fuel-rich gas generator cycle engines that use liquid oxygen(Lox) and Kerosene(Jet-A1) as the propellant combination. It started to develop in 2010 and first launched on October 21, 2021. The paper presents the development history of the upper-stage engine and combustion test results of the upper-stage engine that can make a seven tons-class vacuum thrust. The upper-stage engine has performed with combustion tests of 96 times and a cumulative combustion time of over 18,143 seconds.

description: Recent results for the QCD phase structure at finite temperature and light-quark chemical potential are summarized, where the cases of N_f = 2 + 1 and N_f = 2+1+1 dynamical quark flavors are considered. Order parameters for the chiral and deconfinement transitions are obtained from solutions of a coupled set of truncated Dyson-Schwinger equations for the quark and gluon propagators of Landau gauge QCD. Based on very good agreement with lattice QCD for zero chemical potential the phase diagram in the whole T-μ-plane and the appearance of a putative critical end-point at large chemical potential are studied.

description: Predation is a major factor driving prey trait diversification and promoting ecological speciation. Consequently, antipredator traits are widely studied among prey species. However, comparative studies that examine how different predators shape the ontogenetic growth of antipredator traits are scarce. In larval dragonflies, abdominal spines are effective traits against predatory fish in fish lakes, which prefer larger prey. However, defensive spines increase mortality in habitats dominated by invertebrate predators (invertebrate lakes), which prefer smaller prey. Thus, species from fish lakes may accelerate spine growth at a later body size compared to species from invertebrate lakes when growing into the preferred prey size range of predatory fish. In this study, we constructed the allometric relationship between spine length and body size and compared the inflexion point of those growth curves in five species of Leucorrhinia dragonfly larvae. We found that fish-lake Leucorrhinia species accelerated spine growth at a larger body size than congenerics from invertebrate lakes. Further, rather than extending spine length constantly through development, fish-lake species rapidly accelerated spine growth at a larger body size. This is likely to be adaptive for avoiding invertebrate predation at an early life stage, which are also present in fish lakes, though in smaller numbers. Our results highlight that comparative studies of ontogenetic patterns in antipredator traits might be essential to develop an integrated understanding of predator–prey interactions.

description: The context of reusable cryogenic liquid rocket engines brings new technological and scientific challenges for control and prognostic aspects. Much progress has been made independently on each facet ([1], [2], and [3]), however, the combination of these is less discussed. With the aim of maximizing the Remaining Useful Life (RUL) of a rocket engine, hybrid prognostic methods to estimate RUL on a Liquid Propellant Reusable Engine (LPRE) are linked to estimation for different control cases. The solicitations coming from the input commands of the system affecting the RUL are presented. The main contribution of the paper consists of the analysis of the RUL estimated from the hybrid method [4] as a function of variant control parameters and different command structures. Also, optimal parameters to ensure a balance between precision and RUL are realized. The paper is structured around three main sections. The comparison of the effects between closed-loop and open-loop on the estimate RUL (LPRE on CNES CARINS Simulator). The analysis of the effects of the regulation parameters (variation of Proportional parameter P and Integral parameter I) on the RUL and the Performance in the case of a SISO (Single Input Single Output) system. Finally, the last part focus on the results concerning the variation of the regulation parameters on an LPRE simulated on CNES CARINS Simulator and their effect on the prognostic. First, the case of an LPRE engine subjected to degradation ([5] and [6]) has been studied. Degradation represents the appearance of cracks in the combustion chamber leading to fuel leakage from the regenerative circuit into the combustion chamber. the hybrid estimate of the RUL is compared for closed-loop and open-loop simulation scenarios. The results show that the Remaining Useful Life is more affected for the system in closed-loop compared to the system drive in open loop. Then, closed-loop parameters gain which influences the RUL, and the associated system performances are analyzed in deep. For the given SISO system drive by a PI regulator, many simulations are carried out to vary the parameters Proportional P and the parameter Integral I. To characterize evolution on the RUL and the performance, two indicators are proposed to drive the analyse and have defined some criteria to improve the performances of the closed-loop versus the prognostic. Results present that there exists a balance between Remaining Useful Life and system performance. Finally, research of a set of optimal control parameters regardless of performance and RUL is performed using a framework of an LPRE engine on the CNES CARINS simulator. Resulting to be able to operate the system with gain parameters in function of their effect on Remaining Useful Life and performance precision.

description: The occurrence of antimicrobial resistance due to the use of antimicrobials is considered to be a main cause for treatment failure of bacterial infections in humans and animals. The right of German veterinarians to use and prescribe medications such as antimicrobials is regulated by the Regulation of Veterinary Pharmacies (TÄHAV). The aim of this study was to investigate the impact of the second amendment to the TÄHAV in 2018 on the occurrence of antimicrobial resistance in selected bacterial pathogens isolated from dogs and cats in Germany. For this purpose, we analyzed antimicrobial susceptibility data from 38 German small animal practices gathered between 2015 and 2021 in cooperation with Laboklin (Labor für klinische Diagnostik GmbH & Co.KG, Bad Kissingen, Germany). Annual cumulative susceptibility data of eight bacterial species were analyzed and compared. The mean value of resistant isolates was determined for each year and supplemented by 95% confidence intervals. Encouraged by the amendment, an increase in sample submissions was observed in Germany. The highest resistance rates to the analyzed substances penicillin G, ampicillin, amoxicillin-clavulanic acid, cefovecin, and enrofloxacin were found for Staphylococcus pseudintermedius (S. pseudintermedius), S. aureus, and Escherichia coli (E. coli). In contrast, resistance rates were low for Pasteurella multocida (P. multocida) and β-hemolytic streptococci. Significant resistance trends (p < 0.05) assumed as influenced by the TÄHAV amendment could be the significant decreases in resistance rates of S. pseudintermedius against penicillin G to 67% (n = 322/479), and ampicillin to 63% (n = 286/453), as well as S. felis against amoxicillin-clavulanic acid and cefovecin to 2% (n = 2/109), furthermore, the reduction in the occurrence of resistance of S. aureus against enrofloxacin to 4% (n = 3/76) in 2021. Moreover, for all species, the efficacy against the analyzed substances was maintained over the study period.

description: As an increasing number of robots have been designed to interact with people on a regular basis, research into human-robot interaction has become more widespread. At the same time, little work has been done on the problem of longterm human-robot interaction, in which a human uses a robot for a period of weeks or months. As people spend more time with a robot, it is expected that how they make sense of the robot - their ?ognitive model?of it - may change over time. In order to identify factors that will be critical to the future development of a quantitative cognitive model of long-term human-robot interaction, a study was conducted involving the Personal Exploration Rover (PER) museum exhibit and the museum employees responsible for it. Results of the study suggest that these critical factors include how people experience successes and failures with the robot (as opposed to how they understand its capabilities) and how people anthropomorphize the robot and talk about anthropomorphization.

description: We consider a two-dimensional strongly localized system defined in a half-space and whose transfer integral in the edge can be different than in the bulk. We predict an unbinding transition, as the edge transfer integral is varied, from a phase where conduction paths are distributed across the bulk to a bound phase where propagation is mainly along the edge. At criticality the logarithm of the conductance follows the $F_1$ Tracy-Widom distribution. We verify numerically these predictions for both the Anderson and the Nguyen, Spivak and Shklovskii models. We also check that for a half-space, i.e., when the edge transfer integral is equal to the bulk transfer integral, the distribution of the conductance is the $F_4$ Tracy-Widom distribution. These findings are strong indications that random signs directed polymer models and their quantum extensions belong to the Kardar-Parisi- Zhang universality class. We have analyzed finite-size corrections at criticality and for a half-plane.

description: In this study, we applied bacterial artificial chromosome (BAC) technology with PRVΔTK/gE/gI as the base material to replace the first, central, and terminal segments of the US3 gene with codon-deoptimized fragments via two-step Red-mediated recombination in E. coli GS1783 cells. The three constructed BACs were co-transfected with gI and part of gE fragments carrying homologous sequences (gI+gE’), respectively, in swine testicular cells. These three recombinant viruses with US3 codon de-optimization ((PRVΔTK&gE-US3deop−1, PRVΔTK&gE-US3deop−2, and PRVΔTK&gE-US3deop−3) were obtained and purified. These three recombinant viruses exhibited similar growth kinetics to the parental AH02LA strain, stably retained the deletion of TK and gE gene fragments, and stably inherited the recoded US3. Mice were inoculated intraperitoneally with the three recombinant viruses or control virus PRVΔTK&gEAH02 at a 107.0 TCID50 dose. Mice immunized with PRVΔTK&gE-US3deop−1 did not develop clinical signs and had a decreased virus load and attenuated pathological changes in the lungs and brain compared to the control group. Moreover, immunized mice were challenged with 100 LD50 of the AH02LA strain, and PRVΔTK&gE-US3deop−1 provided similar protection to that of the control virus PRVΔTK&gEAH02. Finally, PRVΔTK&gE-US3deop−1 was injected intramuscularly into 1-day-old PRV-negative piglets at a dose of 106.0 TCID50. Immunized piglets showed only slight temperature reactions and mild clinical signs. However, high levels of seroneutralizing antibody were produced at 14 and 21 days post-immunization. In addition, the immunization of PRVΔTK&gE-US3deop−1 at a dose of 105.0 TCID50 provided complete clinical protection and prevented virus shedding in piglets challenged by 106.5 TCID50 of the PRV AH02LA variant at 1 week post immunization. Together, these findings suggest that PRVΔTK&gE-US3deop−1 displays great potential as a vaccine candidate.

description: Phosphatidylserine lipids are anionic molecules present in eukaryotic plasma membranes, where they have essential physiological roles. The altered distribution of phosphatidylserine in cells such as apoptotic cancer cells, which, unlike healthy cells, expose phosphatidylserine, is of direct interest for the development of biomarkers. We present here applications of a recently implemented Depth-First-Search graph algorithm to dissect the dynamics of transient water-mediated lipid clusters at the interface of a model bilayer composed of 1-palmytoyl-2-oleoyl-sn-glycero-2-phosphatidylserine (POPS) and cholesterol. Relative to a reference POPS bilayer without cholesterol, in the POPS:cholesterol bilayer there is a somewhat less frequent sampling of relatively complex and extended water-mediated hydrogen-bond networks of POPS headgroups. The analysis protocol used here is more generally applicable to other lipid:cholesterol bilayers.

description: The latency of a perception system is crucial for a robot performing interactive tasks in dynamic human environments. We present MOPED, a fast and scalable perception system for object recognition and pose estimation. MOPED builds on POSESEQ, a state of the art object recognition algorithm, demonstrating a massive improvement in scalability and latency without sacrificing robustness. We achieve this with both algorithmic and architecture improvements, with a novel feature matching algorithm, a hybrid GPU/CPU architecture that exploits parallelism at all levels, and an optimized resource scheduler. Using the same standard hardware, we achieve up to 30× improvement on real-world scenes.
