 Cydia oxytropidana Nel & Varenne 2016a: 36, figs. 18, 19a, 20a.
 Examined material. Holotype Ƌ: France, Hautes-Alpes, La Roche-de-Rame, 30.V.2015, J. Nel leg. (TLMF). Paratype Ƌ, idem (TLMF). Paratype ♀, idem (TLMF).

 Identity: Cydia oxytropidis (Martini, 1912), syn. nov. (Fig. 6)
 Remarks. Cydia oxytropidana was described from a male holotype and several paratypes of both sexes. Nel & Varenne (2016a) compared the species with C. oxytropidis (Martini, 1912) but based their diagnosis exclusively on genitalia figures published by Razowski (2003). Whereas the discussed differences in male genitalia are subtle, the females of both species seemed to differ strikingly e.g. by the lack of signa in C. oxytropidis vs well developed in C. oxytropidana. However, re-assessment of allegedly diagnostic characters gave a different picture. Male genitalia show intraspecific variation that does not support two species. Similarly female genitalia characters underly some variation as shown by Nel & Varenne (2016a) for C. oxytropidana. Paired signa in female genitalia are a basic structure in Cydia and well developed in all European species. It is therefore suspected that the figure of C. oxytropidis in Razowski (2003), based on a specimen from Ukraine, is erroneous. Other specimens of C. oxytropidis from the Ukraine have normally developed signa (Kavurka 2010) and the same applies to material from Central Europe dissected by PH. Finally we have been able to obtain DNA barcode sequences of the holotype and two paratypes of C. oxytropidana which also fully correspond to C. oxytropidis. We therefore synonymize C. oxytropidana with C. oxytropidis.

description: Despite extensive testing and correctness certification of their functional semantics, a number of compiler optimizations have been shown to violate security guarantees implemented in source code. While prior work has shed light on how such optimizations may introduce semantic security weaknesses into programs, there remains a significant knowledge gap concerning the impacts of compiler optimizations on non-semantic properties with security implications. In particular, little is currently known about how code generation and optimization decisions made by the compiler affect the availability and utility of reusable code segments called gadgets required for implementing code reuse attack methods such as return-oriented programming. In this paper, we bridge this gap through a study of the impacts of compiler optimization on code reuse gadget sets. We analyze and compare 1,187 variants of 20 different benchmark programs built with two production compilers (GCC and Clang) to determine how their optimization behaviors affect the code reuse gadget sets present in program variants with respect to both quantitative and qualitative metrics. Our study exposes an important and unexpected problem; compiler optimizations introduce new gadgets at a high rate and produce code containing gadget sets that are generally more useful to an attacker than those in unoptimized code. Using differential binary analysis, we identify several undesirable behaviors at the root of this phenomenon. In turn, we propose and evaluate several strategies to mitigate these behaviors. In particular, we show that post-production binary recompilation can effectively mitigate these behaviors with negligible performance impacts, resulting in optimized code with significantly smaller and less useful gadget sets.

Resonant nonequilibrium temperatures

description: We investigate nonequilibrium temperatures in a two-state system driven to a nonequilibrium steady state by the action of an oscillatory field. The nonequilibrium temperature is determined by coupling a small cavity or probe to the nonequilibrium system and studying the fluctuating noise in the cavity, as has been proposed in the context of glassy systems. We show the presence of resonant effects in the nonequilibrium temperature and discuss the existence of a constitutive steady-state equation in such nonequilibrium conditions. We propose this simple model as an excellent system to carry out experimental measurements of nonequilibrium temperatures. This may help to better understand the physical meaning of this elusive concept.

description: Aiming at realizing novel vision augmentation experiences, this paper proposes the IlluminatedFocus technique, which spatially defocuses real-world appearances regardless of the distance from the user's eyes to observed real objects. With the proposed technique, a part of a real object in an image appears blurred, while the fine details of the other part at the same distance remain visible. We apply Electrically Focus-Tunable Lenses (ETL) as eyeglasses and a synchronized high-speed projector as illumination for a real scene. We periodically modulate the focal lengths of the glasses (focal sweep) at more than 60 Hz so that a wearer cannot perceive the modulation. A part of the scene to appear focused is illuminated by the projector when it is in focus of the user's eyes, while another part to appear blurred is illuminated when it is out of the focus. As the basis of our spatial focus control, we build mathematical models to predict the range of distance from the ETL within which real objects become blurred on the retina of a user. Based on the blur range, we discuss a design guideline for effective illumination timing and focal sweep range. We also model the apparent size of a real scene altered by the focal length modulation. This leads to an undesirable visible seam between focused and blurred areas. We solve this unique problem by gradually blending the two areas. Finally, we demonstrate the feasibility of our proposal by implementing various vision augmentation applications.

Dynamical Theory of Phase Transitions and Topological Defect Formation in the Early Universe

Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: We review the current issues of nonequilibrium phase transitions, in particular, in the early universe. Phase transitions cannot maintain thermal equilibrium and become nonequilibrium when the thermal relaxation time scale is greater than the dynamical time scale. Nonequilibrium phase transitions would have happened in certain evolution stages of the early universe because the rapid expansion quenched matter fields. We apply the recently introduced Liouville-von Neumann method, another canonical method, to nonequilibrium phase transitions in the Minkowski spacetime and find the scaling behavior of domain sizes. Topological defects are thus determined by the dynamical processes of nonequilibrium phase transitions. However, the expansion of the universe freezes domain growth in the comoving frame and thus leads to a scale-invariant domain size. We also discuss the physical implications of nonequilibrium phase transitions in the early universe.

When good fences make bad neighbors : fixed borders, state weakness, and international conflict

description: Since the end of World War II, the norm of fixed borders—the proscription against foreign conquest and annexation of homeland territory—has gained prevalence in world politics. But have fixed borders made international conflict less frequent? Observers might assume they have, given that territorial issues have historically been a major cause of war. However, among sociopolitically weak states (i.e., states that lack legitimate and effective governmental institutions), fixed borders can actually increase instability and conflict. Good fences can make bad neighbors.

description: In December 2019, a novel coronavirus (COVID-19) spread so quickly around the world that many countries had to set mandatory face mask rules in public areas to reduce the transmission of the virus. To monitor public adherence, researchers aimed to rapidly develop efficient systems that can detect faces with masks automatically. However, the lack of representative and novel datasets proved to be the biggest challenge. Early attempts to collect face mask datasets did not account for potential race, gender, and age biases. Therefore, the resulting models show inherent biases toward specific race groups, such as Asian or Caucasian. In this work, we present a novel face mask detection dataset that contains images posted on Twitter during the pandemic from around the world. Unlike previous datasets, the proposed Bias-Aware Face Mask Detection (BAFMD) dataset contains more images from underrepresented race and age groups to mitigate the problem for the face mask detection task. We perform experiments to investigate potential biases in widely used face mask detection datasets and illustrate that the BAFMD dataset yields models with better performance and generalization ability. The dataset is publicly available at https://github.com/Alpkant/BAFMD.

 Identity: Dichrorampha melaniana Nel & Varenne, 2016
 Remarks. Dichrorampha melaniana was decribed from three female specimens from the French Alps and compared with D. alpigenana Heinemann, 1863. The male sex was published only a year later by Nel & Varenne (2017a), based on a single specimen. The authors had not been aware of another related species, namely D. tarmanni Huemer, 2009, which occurs in nearby Italy. Both species are close in genitalia with only subtle differences in the female but seemingly better separated in the male. The successfully sequenced holotype of D. melaniana fully corresponds to D. tarmanni as well as to several other species of Dichrorampha. It appears that barcode sharing is widespread in this group of closely related species. Though the validity of D. melaniana seems well supported from available figures it will be necessary to study the intraspecific variation and to re-assess the species group of D. plumbana (Scopoli, 1763).

description: In the first paper of this series, we presented a detailed high-resolution spectroscopic study of CPD - 41degr7742, deriving for the first time an orbital solution for both components of the system. In this second paper, we focus on the analysis of the optical light curve and on recent XMM-Newton X-ray observations. In the optical, the system presents two eclipses, yielding an inclination i ~ 77degr. Combining the constraints from the photometry with the results of our previous work, we derive the absolute parameters of the system. We confirm that the two components of CPD - 41degr7742 are main sequence stars (O9 V + B1-1.5 V) with masses (M_1 ~ 18 Msol and M_2 ~ 10 Msol) and respective radii (R_1 ~ 7.5 Rsol and R_2 ~ 5.4 Rsol) close to the typical values expected for such stars. We also report an unprecedented set of X-ray observations that almost uniformly cover the 2.44-day orbital cycle. The X-ray emission from CPD - 41degr7742 is well described by a two-temperature thermal plasma model with energies close to 0.6 and 1.0 keV, thus slightly harder than typical early-type emission. The X-ray light curve shows clear signs of variability. The emission level is higher when the primary is in front of the secondary. During the high emission state, the system shows a drop of its X-ray emission that almost exactly matches the optical eclipse. We interpret the main features of the X-ray light curve as the signature of a wind-photosphere interaction, in which the overwhelming primary O9 star wind crashes into the secondary surface. Alternatively the light curve could result from a wind-wind interaction zone located near the secondary star surface. As a support to our interpretation, we provide a phenomenological geometric model that qualitatively reproduces the observed modulations of the X-ray emission.

description: A 6-cell solid oxide electrolysis stack was tested under H2O + CO2 co-electrolysis conditions. The cells used in the stack consisted of a nickel-yttria stabilized zirconia (Ni-YSZ) fuel electrode, YSZ electrolyte and lanthanum strontium cobaltite-gadolinium doped ceria (LSC-GDC) composite oxygen electrode. The aim of this study was to investigate the stack durability when operated under dynamic load conditions simulating a wind energy powered SOEC stack for synthesis gas production. The degradation of the stack was observed to be less than 1%/1000 h in terms of area specific resistance during the 1000 hours operation. Detailed electrochemical analysis revealed a constant ohmic resistance, indicating intact contact in the stack. Only minor degradation was observed, mainly due to the fuel electrode process. The overall stack voltage degradation rate was 0.8%/1000 h.

The project features a unique design in which multiple experimental replicates are collected by three different laboratories at discrete locations for all candidate compounds tested. To limit confounding factors that may influence experimental reproducibility, we develop standardized operating procedures (SOPs) for all experimental procedures. Here we provide the CITP SOP for Obeticholic acid.

description: Background
 The use of a clinical decision support system for assessing the quality of care, based on computerized clinical guidelines (GLs), is likely to improve care, reduce costs, save time, and enhance the staff's capabilities.
 Objectives
 Implement and evaluate a system for assessment of the quality of the care, in the domain of management of pressure ulcers, by investigating the level of compliance of the staff to the GLs.
 Methods
 Using data for 100 random patients from the local EMR system we performed a technical evaluation, checking the applicability and usability, followed by a functional evaluation of the system investigating the quality metrics given to the compliance of the medical's staff to the protocol. We compared the scores given by the nurse when supported by the system, to the scores given by the nurse without the system's support, and to the scores given by the system. We also measured the time taken to perform the assessment with and without the system's support.
 Results
 There were no significant differences in the scores of most measures given by the nurse using the system, compared to the scores given by the system. There were also no significant differences across the values of most quality measures given by the nurse without support compared to the values given by the nurse with support. Using the system, however, significantly reduced the nurse's average assessment time.
 Conclusions
 Using an automated quality-assessment system, may enable a senior nurse, to quickly and accurately assess the quality of care. In addition to its accuracy, the system considerably reduces the time taken to assess the various quality measures.

description: We study the linear instability of the charged massless scalar perturbation in regularized 4D charged Einstein-Gauss-Bonnet-AdS black holes by exploring the quasinormal modes. We find that the linear instability is triggered by superradiance. The charged massless scalar perturbation becomes more unstable when increasing the Gauss-Bonnet coupling constant or the black hole charge. Meanwhile, decreasing} the AdS radius will make the charged massless scalar perturbation} more stable. The stable region in parameter space $(α,Q,Λ)$ is given. Moreover, we find that the charged massless scalar perturbation is more unstable for larger scalar charge. The modes of multipoles are more stable than that of the monopole.

description: We study neutron stars in a varying speed of light (VSL) theory of gravity in which the local speed of light depends upon the value of a scalar field $ϕ$. We find that the masses and radii of the stars are strongly dependent on the strength of the coupling between $ϕ$ and the matter field and that for certain choices of coupling parameters, the maximum neutron star mass can be arbitrarily small. We also discuss the phenomenon of cosmological evolution of VSL stars (analogous to the gravitational evolution in scalar-tensor theories) and we derive a relation showing how the fractional change in the energy of a star is related to the change in the cosmological value of the scalar field.

description: Visual Place Recognition (VPR) is the process of recognising a previously visited place using visual information, often under varying appearance conditions and viewpoint changes and with computational constraints. VPR is related to the concepts of localisation, loop closure, image retrieval and is a critical component of many autonomous navigation systems ranging from autonomous vehicles to drones and computer vision systems. While the concept of place recognition has been around for many years, VPR research has grown rapidly as a field over the past decade due to improving camera hardware and its potential for deep learning-based techniques, and has become a widely studied topic in both the computer vision and robotics communities. This growth however has led to fragmentation and a lack of standardisation in the field, especially concerning performance evaluation. Moreover, the notion of viewpoint and illumination invariance of VPR techniques has largely been assessed qualitatively and hence ambiguously in the past. In this paper, we address these gaps through a new comprehensive open-source framework for assessing the performance of VPR techniques, dubbed "VPR-Bench". VPR-Bench (Open-sourced at: https://github.com/MubarizZaffar/VPR-Bench) introduces two much-needed capabilities for VPR researchers: firstly, it contains a benchmark of 12 fully-integrated datasets and 10 VPR techniques, and secondly, it integrates a comprehensive variation-quantified dataset for quantifying viewpoint and illumination invariance. We apply and analyse popular evaluation metrics for VPR from both the computer vision and robotics communities, and discuss how these different metrics complement and/or replace each other, depending upon the underlying applications and system requirements.

description: Connectivity maintenance is an essential aspect to consider while controlling a multi-robot system. In general, a multi-robot system should be connected to obtain a certain common objective. Connectivity must be kept regardless of the control strategy or the objective of the multi-robot system. Two main methods exist for connectivity maintenance: keep the initial connections (local connectivity) or allow modifications to the initial connections, but always keeping the overall system connected (global connectivity). In this paper we present a method that allows, at the same time, to maintain global connectivity and to implement the desired control strategy (e.g., consensus, formation control, coverage), all in an optimized fashion. For this purpose, we defined and implemented a Control Barrier Function that can incorporate constraints and objectives. We provide a mathematical proof of the method, and we demonstrate its versatility with simulations of different applications.

We also reconsider the computation of the CS S-matrix in terms of particles with fractional charge.

description: Motivated by recent results reporting the instability of horizonless objects with stable light rings, we revisit the linearized stability of such structures. In particular, we consider an exterior Kerr spacetime truncated at a surface where Dirichlet conditions on a massless scalar are imposed.This spacetime has ergoregions and light rings when the surface is placed sufficiently deep in the gravitational potential. We establish that the spacetime is linearly, mode-unstable when it is sufficiently compact, in a mechanism associated with the ergoregion. In particular, such instability has associated zero-modes. At large multipole number the critical surface location for zero modes to exist is precisely the location of the ergosurface along the equator. We show that such modes don't exist when the surface is outside the ergoregion, and that any putative linear instability mechanism acts on timescales $τ\gtrsim 10^5 M$, where $M$ is the black hole mass. Our results indicate therefore that at least certain classes of objects are linearly stable in the absence of ergoregions, even if rotation and light rings are present.
description: 13 pages, 12 figures, substantial improvements and clarifications. Results remain unchanged: this work shows that a class of compact object models are linearly stable when light rings are present but ergoregions are absent. Version to appear in Physical Review D

 Epiblema bonifaciensis Nel, Varenne & Peslier 2020: 71, figs. 19–21.
 Examined material. Holotype Ƌ: France, Corse-du-Sud, Bonifacio, 80 m, uv, 6.VI.2019, Th. Varenne leg., genitalia slide TV n°6964 (RCTV).
BOLD Specimen ID TLMF 28240; BOLD Sequence ID PALEA230-20.
BIN: not barcode compliant.
 Identity: Epiblema bonifaciensis Nel, Varenne & Peslier 2020, identity uncertain.
 Remarks. Epiblema bonifaciensis was described from a single male holotype and compared with several congeneric species, particularly the closest taxon E. graphana (Treitschke, 1835) (Nel et al 2020). The DNA barcode of the successfully sequenced holotype is not barcode compliant and ca. 1.4% divergent from the nearest neighbour, E. graphana. The latter species shows considerable intraspecific barcode variation with altogether three BINs, and E. bonifaciensis nests in a group near the most widespread cluster. The small differences in male genitalia and also in the later described female (Varenne et al. 2020) may be due to individual variation and distortion of genitalia (female ostium), and require careful re-assessment in the context of a revision of the intraspecific variation of E. graphana.

Invariant correlational entropy as a signature of quantum phase transitions in nuclei
Creators: name: Volya, Alexander

Year: 2003
Subjects: subject: Nuclear Theory (nucl-th)

description: We study phase transformations in finite nuclei as a function of interaction parameters. The signature of a transition is given by invariant correlational entropy that reflects the sensitivity of an individual many-body state to changes of external parameters; peaks in this quantity indicate the critical regions. This approach is able to reveal the pairing phase transition, identify the isovector and isoscalar pairing regions and determine the role of other interactions. We show the examples of the phase diagram in the parameter space.

Hysteretic wave drag in shallow water

description: During motion from deep to shallow water, multiple equilibria may emerge, each with identical drag - a phenomenon that can be explained by a localised amplification of the wave drag near the shallow wave speed. The implication of this is the emergence of several previously unstudied bifurcation patterns and hysteresis routes. Here, we address these nonlinear dynamics by considering the quasi-steady motion of a body between deep and shallow water, where the depth is slowly varying. We survey several theoretical models for the drag, compare these against our tow-tank experimental measurements, and then use the validated theory to explore the bifurcation patterns using two parameters: the depth of motion and the forcing. In particular, using a case study of a lake with a sinusoidal depth profile, we illustrate that hysteresis effects can play a significant role on the speed of motion and journey time, presenting interesting implications for naval and racing applications.
Causality-Aware Local Interpretable Model-Agnostic Explanations

description: A main drawback of eXplainable Artificial Intelligence (XAI) approaches is the feature independence assumption, hindering the study of potential variable dependencies. This leads to approximating black box behaviors by analyzing the effects on randomly generated feature values that may rarely occur in the original samples. This paper addresses this issue by integrating causal knowledge in an XAI method to enhance transparency and enable users to assess the quality of the generated explanations. Specifically, we propose a novel extension to a widely used local and model-agnostic explainer, which encodes explicit causal relationships within the data surrounding the instance being explained. Extensive experiments show that our approach overcomes the original method in terms of faithfully replicating the black-box model's mechanism and the consistency and reliability of the generated explanations.

description: Determination of the star formation rate can be done using mid-IR photometry or Balmer line luminosity after a proper correction for extinction effects. Both methods show convergent results while those based on UV or on [OII]3727 luminosities underestimate the SFR by factors ranging from 5 to 40 for starbursts and for luminous IR galaxies, respectively. Most of the evolution of the cosmic star formation density is related to the evolution of luminous compact galaxies and to luminous IR galaxies. Because they were metal deficient and were forming stars at very high rates (40 to 100 solar mass per year), it is probable that these (massive) galaxies were actively forming the bulk of their stellar/metal content at z < 1.

Nuclear Spin-Lattice Relaxation in One-Dimensional Heisenberg Ferrimagnets: Three-Magnon versus Raman Processes

description: Nuclear spin-lattice relaxation in one-dimensional Heisenberg ferrimagnets is studied by means of a modified spin-wave theory. We consider the second-order process, where a nuclear spin flip induces virtual spin waves which are then scattered thermally via the four-magnon exchange interaction, as well as the first-order process, where a nuclear spin directly interacts with spin waves via the hyperfine interaction. We point out a possibility of the three-magnon relaxation process predominating over the Raman one and suggest model experiments.

description: Conflict is an inseparable element of social life. It is present in different areas of relationships between peoples. It is considered, by some, a disorder that disrupts society and for others it is something positive, and that boosts social change. Across the world, even in rainy regions, people are involved in conflicts over water. It has increased the debate about who should own it, control it or have access to it. This article aims, as of recent research within the social sciences, to analyze issues related to the impacts of dam construction, the meanings attributed to water as a symbolic and ritual element, the management of irrigation systems, the commodification of water by industry and the knowledge and practices associated with water from the Luso, African, and Brazilian contexts.

 Remarks. Eucosma bimaculatana was described from two males from Corsica (Labonne et al. 2017), whereas the female was reported two years later (Varenne et al. 2019).The successfully sequenced holotype clusters separately from other barcoded Eucosma in a unique BIN with a distance of ca. 4% to the nearest neighbour, E. glomerana (Walsingham, 1879) from North America and ca. 5% to the nearest neighbour in Europe, the morphologically similar E. tripoliana (Barrett, 1880). However, the relationship to E. fervidana (Zeller, 1847), a species without barcode sequence so far, needs re-assessment.

description: Resistive Plate Chamber detectors are largely used in current High Energy Physics experiments, typically operated in avalanche mode with large fractions of Tetrafluoroethane (C2H2F4), a gas recently banned by the European Union due to its high Global Warming Potential (GWP). An intense R&D activity is ongoing to improve RPC technology in view of future HEP applications. In the last few years the RPC EcoGas@GIF++ Collaboration has been putting in place a joint effort between the ALICE, ATLAS, CMS, LHCb/SHiP and EP-DT Communities to investigate the performance of present and future RPC generations with eco-friendly gas mixtures. Detectors with different layout and electronics have been operated with ecological gas mixtures, with and without irradiation at the CERN Gamma Irradiation Facility (GIF++). Results of these performance studies together with plans for an aging test campaign are discussed in this article.

description: There is an abundance of empirical evidence in the numerical relativity literature that the form in which the Einstein evolution equations are written plays a significant role in the lifetime of numerical simulations. This paper attempts to present a consistent framework for modifying any system of evolution equations by adding terms that push the evolution toward the constraint hypersurface. The method is, in principle, applicable to any system of partial differential equations which can be divided into evolution equations and constraints, although it is only demonstrated here through an application to the Maxwell equations.

description: On-farm cropping systems research involving banana (Musa sp.) dasheen (Colocasia esculenta) and cowpeas (Vigna unguiculata) was initiated on six sites with similar production environments and soil type (Aquic Tropudults) in Fond Assau, St. Lucia. The prevalent farmers' pattern (Control) was compared against experimental alternatives. The use of partial budgets and performance criteria such as returns above variable costs (RAVC) showed that the alternatives are 16-30% superior than that of the control. Alternative patterns indicated a marginal benefit-cost ratio (MBCR) varying from 2.4 to 4.7 as compared to the farmers' existing pattern. Yield, yield parameters, leaf characteristics and growth of banana at 7 months after planting were unaffected by the various treatments. However, the production cycle was extended to a maximum of 17 days in banana + 2 dasheen + 3 cowpeas. The cropping systems significantly reduced the weed growth.

description: We demonstrate a scheme for optically patterning nuclear spin polarization in semiconductor/ferromagnet heterostructures. A scanning time-resolved Kerr rotation microscope is used to image the nuclear spin polarization that results when GaAs/MnAs epilayers are illuminated with a focused laser having a Gaussian profile. Rather than tracking the intensity profile of the laser spot, these images reveal that the nuclear polarization forms an annular lateral structure having circular symmetry with a dip rather than a peak at its center.
