description: On the basis of various data such as ALMA, JVLA, Chandra, {\it Herschel}, and {\it Spitzer}, we confirmed that two protostellar candidates in Oph-A are bona fide protostars or proto-brown dwarfs (proto-BDs) in extremely early evolutionary stages. Both objects are barely visible across infrared (IR, i.e., near-IR to far-IR) bands. The physical nature of the cores is very similar to that expected in first hydrostatic cores (FHSCs), objects theoretically predicted in the evolutionary phase prior to stellar core formation with gas densities of $\sim$ 10$^{11-12}$ cm$^{-3}$. This suggests that the evolutionary stage is close to the FHSC formation phase. The two objects are associated with faint X-ray sources, suggesting that they are in very early phase of stellar core formation with magnetic activity. In addition, we found the CO outflow components around both sources which may originate from the young outflows driven by these sources. The masses of these objects are calculated to be $\sim 0.01-0.03$ $M_\odot$ from the dust continuum emission. Their physical properties are consistent with that expected from the numerical model of forming brown dwarfs. These facts (the X-ray detection, CO outflow association, and FHSC-like spectral energy distributions) strongly indicate that the two objects are proto-BDs or will be in the very early phase of protostars which will evolve more massive protostars if they gain enough mass from the surroundings. The ages of these two objects are likely to be within $\sim 10^3$ years after the protostellar core (or second core) formation, taking into account the outflow dynamical times ($\lesssim$ 500 yrs).

description: We analyze the interplay between contact geometry and Gabor filters signal analysis in geometric models of the primary visual cortex. We show in particular that a specific framed lattice and an associated Gabor system is determined by the Legendrian circle bundle structure of the $3$-manifold of contact elements on a surface (which models the V1-cortex), together with the presence of an almost-complex structure on the tangent bundle of the surface (which models the retinal surface). We identify a scaling of the lattice, also dictated by the manifold geometry, that ensures the frame condition is satisfied. We then consider a $5$-dimensional model where receptor profiles also involve a dependence on frequency and scale variables, in addition to the dependence on position and orientation. In this case we show that a proposed profile window function does not give rise to frames (even in a distributional sense), while a natural modification of the same generates Gabor frames with respect to the appropriate lattice determined by the contact geometry.

description: Digital color imaging relies on spectral filters on top of a pixelated sensor, such as a CMOS image sensor. An important parameter of imaging devices is their resolution, which depends on the size of the pixels. For many applications, a high resolution is desirable, consequently requiring small spectral filters. Dielectric nanostructures, due to their resonant behavior and its tunability, offer the possibility to be assembled into flexible and miniature spectral filters, which could potentially replace conventional pigmented and dye-based color filters. In this paper, we demonstrate the generation of transmissive structural colors based on uniform-height amorphous silicon nanostructures. We optimize the structures for the primary RGB colors and report the construction of sub-micrometer RGB filter arrays for a pixel size down to 0.5 μm.

description: Probabilistic pushdown automata (pPDA) are a standard operational model for programming languages involving discrete random choices and recursive procedures. Temporal properties are useful for specifying the chronological order of events during program execution. Existing approaches for model checking pPDA against temporal properties have focused mostly on $ω$-regular and LTL properties. In this paper, we give decidability and complexity results for the model checking problem of pPDA against $ω$-visibly pushdown languages that can be described by specification logics such as CaRet. These logical formulae allow specifying properties that explicitly take the structured computations arising from procedural programs into account. For example, CaRet is able to match procedure calls with their corresponding future returns, and thus allows to express fundamental program properties such as total and partial correctness.

Furthermore, we provide a general description of the transitive groups of degree p-squared whose Sylow p-subgroup is such a wreath product, and explicitly determine most of them. As applications, we solve the Cayley Isomorphism problem for Cayley objects of an abelian group of order p-squared, explicitly determine the full automorphism group of Cayley graphs of abelian groups of order p-squared, and find all nonnormal Cayley graphs of order p-squared.

description: We suggest a new approach to study the cosmis ray (CR) mass composition in the energy region from 30 TeV/nucleus up to the "knee" region, i.e. up to a few PeV/nucleus, using an array of imaging atmospheric Cherenkov telescopes (IACTs) of a special architecture. This array consists of telescopes with a relatively small mirror size (~10 square meters) separated from each other by large distances (~500 meters) and equipped by multichannel cameras with a modest pixel size (0.3-0.5 degree) and a sufficiently large viewing angle (6-7 degree). Compared to traditional IACT systems (like HEGRA, HESS or VERITAS) the IACT array considered here could provide a very large detection area (several square kilometers or more). At the same time, it allows an accurate measurement of the energy of CR induced air showers (the energy resolution ranges within 25-35%) and an effective separation of air showers created by different nuclei. Particularly, it is possible to enrich air showers belonging to the nucleus group assigned for selection up to ~90% purity at a detection efficiency of 15-20% of such showers.

description: A system of spinless fermions in $d=1+ε$ dimensions, at zero-temperature and in random potential is studied using the perturbative renormalization group to first order in disorder and to second order in interaction. We find a superconductor-to- Anderson insulator quantum fixed point at an infinitesimal value of disorder and calculate the correlation length and the dynamical exponents to the lowest order in $ε$ and in interaction. The scaling of conductivity with temperature and the behavior of characteristic temperature scales on both sides of the transition is determined. The model may have relevance for a p-wave superconductor at low temperatures in strongly disordered media.

description: In Côte d'Ivoire, one of the most recurrent manifestations of climate change results in long periods of drought lasting more than four consecutive months in the most-affected cocoa production areas. These droughts compromise cacao establishment, productivity and quality, which in turn threaten the longer-term sustainability of Ivorian cocoa farming. To address this constraint, one of the areas of research explored by breeders, is the identification of relevant criteria to assess the resistance of cocoa trees to drought, as a means to developing more climate-resilient genotypes. The purpose of this study is to show how adult vegetative vigor, leaf density and flushing intensity have proven to be relevant criteria for evaluating the resistance of cocoa trees to drought. A trial involving four agro-climatic zones (Bouaflé, Abengourou, Divo and Soubré), two of which experience significant rainfall deficits (Bouaflé and Abengourou), was set up in Côte d'Ivoire. The plant material, planted in two plots per zone, was made up of 15 CNRA families common to each agro-climatic zone and 10 to 15 free progenies, selected in each zone by the cocoa producers for their superior agronomic and technological performance. Eleven criteria were used to evaluate the plant material: i) vegetative vigor measured by the diameter at the collar; ii) trunk circumference at 130 cm above the ground; iii) tree height; iv) foliage density; v) leaf density; vi) flush intensity; vii) drought-sensitivity score ; viii) total number of cherelles per tree; ix) cherelle wilt rate; x) cumulative potential production (2015 to 2018), and xi) bean weight (weight of 100 dry cocoa beans).
The results showed a highly significant zone x family interaction (probability < 0.0001) for all the traits studied. In particular, six hybrid families were ranked in the top ten across all study areas, indicating resilience in the more challenging agro-climatic zones. Of these eleven criteria, those having best characterized the six families thus selected are, in decreasing order of importance: 'i) leaf density; ii) vegetative vigor and iii) flush intensity. The use of these three criteria in the selection of drought-resilient plant material is envisaged.

description: In this paper, the concept of a double divided injection molding mold is investigated. It consists of a two-part separated mold cavity and a two-part mold core which allows rapid heating and cooling of cavities in injection molding processes. The inner low mass molds of the cavities are heated rapidly with infrared radiators. Hence, the injection molding process starts with high temperature cavities manufacturing high quality plastic products in an economical way. Starting with a rating of different variothermal heating concepts, a need of more flexible variothermal mold heating technology is derived. Heat transfer mechanisms conduction, convection and radiation between high mass body and low mass inlay are explained. The advantage of a variothermal mold heating by infrared radiation is demonstrated by a mathematical and physical modeling of heat exchange. Finally, the influences on heat transfer via infrared and contact cooling are investigated experimentally. The results show promising recognitions regarding the potential of variothermal molds using infrared radiation.
description: In diesem Beitrag wird das Konzept einer doppelt geteilten Spritzgussform untersucht. Diese besteht aus einem zweiteiligen Kavität als Einleger und einem zweiteiligen Werkzeugkörper, der ein schnelles Erwärmen und Kühlen im Spritzgussverfahren ermöglicht. Die Einleger mit geringer Masse werden mit Infrarotstrahlern erwärmt. Zu Beginn des Spritzgussprozesses weist die Kavität eine hohe Temperatur auf, wodurch sich qualitativ hochwertige Kunststoffformteile auf wirtschaftliche Weise herstellen lassen. Ausgehend von der Bewertung verschiedener variothermer Heizkonzepte wird der Bedarf an flexiblerer variothermer Werkzeugtemperierung abgeleitet. Wärmeübertragungsmechanismen Leitung, Konvektion und Strahlung zwischen dem Werkzeugkörper mit hoher Masse und dem Einleger mit niedriger Masse werden erläutert. Der Vorteil einer variothermen Werkzeugtemperierung durch Infrarotstrahlung wird durch eine mathematische und physikalische Modellierung des Wärmeaustauschs herausgestellt. Abschließend werden die Einflüsse auf die Wärmeübertragung über Infrarot und Kontaktkühlung experimentell untersucht. Die Ergebnisse generieren Erkenntnisse über das Potenzial von variotherm temperierten Werkzeugen mittels Infrarotstrahlung.

description: This is an educational board game intended to teach the basics of the Essence Theory of Software Engineering. The board game was used in an academic study found on arXiv (https://arxiv.org/abs/1809.08656).
In the light of the findings of the study, we suggest that the board game can be used to teach a method agnostic approach to SE, as well as the importance of communication and teamwork in SE projects. It is likely best-suited for teaching newer IT students SE project work as more senior students are likely to get less out of the game.
The game itself is played as a team against the game board. It is best played in teams of 4-5 as the game does not scale well with the amount of players, meaning the more players a team has the easier the game is to win. All the materials needed to play the game, including the detailed instructions, are found in the files of this contribution.

Generating quasiperiodic pulsar glitches using a state-dependent Poisson process

description: Glitching pulsars fall broadly into two statistical classes: those with Poisson-like waiting times and power-law sizes, and those with unimodal waiting times and sizes. Previous glitch modeling based on a state-dependent Poisson process readily generates Poisson-like behaviour but struggles to produce unimodal waiting times or sizes. Here it is shown that, when some of the inputs to the model are modified, both classes of statistical behaviour can be reproduced by varying a single control parameter related to the spin-down rate. The implications for past and future glitch observations and the underlying microphysical mechanism are explored briefly.

description: The relationship of body mass index (BMI) with lung function and COPD has been previously described in several high-income settings. However, few studies have examined this relationship in resource-limited settings where being underweight is more common. We evaluated the association between BMI and lung function outcomes across 14 diverse low- and middle-income countries. We included data from 12,396 participants aged 35–95 years and used multivariable regressions to assess the relationship between BMI with either COPD and lung function while adjusting for known risk factors. An inflection point was observed at a BMI of 19.8 kg/m2. Participants with BMI < 19.8 kg/m2 had a 2.28 greater odds (95% CI 1.83–2.86) of having COPD and had a 0.21 (0.13–0.30) lower FEV1 and 0.34 (0.27–0.41) lower FEV1/FVC z-score compared to those with BMI ≥ 19.8 kg/m2. The association with lung function remained even after excluding participants with COPD. Individuals with lower BMI were more likely to have COPD and had lower lung function compared to those in higher BMI. The association with lung function remained positive even after excluding participants with COPD, suggesting that being underweight may also play a role in having worse lung function.

description: Description of Parmeliella testacea from the Tamentout Forest:
 The species has a squamulose to minutely foliose thallus composed of pale chestnut-brown to gray-brown lobes, forming a rosette. It tightly adheres to its substrate with distinct peripheral lobes and its upper surface is fragile (Fig. 4). When wet, the thallus turns dark blue-gray. The thallus is sorediate with dark gray, coarsely granular soredia formed in predominantly marginal, sometimes also laminar, button-shaped soralia. These soralia are initially concolorous with the thallus surface, their soredia sometimes brittle, on a ± uniform surface, which may become coarsely cracked along the margin. The thallus resides on an arachnoid hypothallus, blue-black in color. In the specimens collected in Algeria, apothecia were not observed; the photobiont is Nostoc.
 Notes: Only a single corticolous specimen of Parmeliella testacea was found in the Tamentout Forest, growing on Q. suber. The species generally appears to be quite rare, and in France its threat status has been assessed according to IUCN red-list criteria as Vulnerable (VU) by Roux et al. (2017). In the past, the species had been reported from England, but it is considered extinct (Cannon et al. 2021).

description: We introduce the one-dimensional PT-symmetric Schrodinger equation, with complex potentials in the form of the canonical superoscillatory and suboscillatory functions known in quantum mechanics and optics. While the suboscillatory-like potential always generates an entirely real eigenvalue spectrum, its counterpart based on the superoscillatory wave function gives rise to an intricate pattern of PT-symmetry-breaking transitions, controlled by the parameters of the superoscillatory function. One scenario of the transitions proceeds smoothly via a set of threshold values, while another one exhibits a sudden jump to the broken PT symmetry. Another noteworthy finding is the possibility of restoration of the PT symmetry, following its original loss, in the course of the variation of the parameters.

description: In this work we present an application of the virtual element method (VEM) to a forming process of hybrid metallic structures by cross-wedge rolling. The modeling of that process is embedded in a thermomechanical framework undergoing large deformations, as outlined in [1, 2]. Since forming processes include mostly huge displacements within a plastic regime, the difficulty of an accurate numerical treatment arises. As shown in [3], VEM illustrates a stable, robust and quadratic convergence rate under extreme loading conditions in many fields of numerical mechanics. Numerically, the forming process is achieved by assigning time-dependent boundary conditions instead of modeling the contact mechanics yielding to a simplified formulation. Based on the two metallic combinations of steel and aluminum, different material properties are considered in the simulations. The purpose of this contribution is to illustrate the effectiveness of such a non-contact macroscopic framework by employing suitable boundary conditions within a virtual element scheme. A comparison with the classical finite element method (FEM) is performed to demonstrate the efficiency of the chosen approach. The numerical examples proposed in this work stem out from the DFG Collaborative Research Centre (CRC) 1153 “Process chain for the production of hybrid high-performance components through tailored forming”.

description: We observed surface acoustic wave (SAW) propagation on a multiferroic material CuB$_2$O$_4$ with use of two interdigital transducers (IDTs). The period of IDT fingers is as short as 1.6 $μ$m so that the frequency of SAW is 3 GHz, which is comparable with that of magnetic resonance. In antiferromagnetic phase, the SAW excitation intensity varied with the magnitude and direction of the magnetic field, owing to the dynamical coupling between SAWs and antiferromagnetic resonance of CuB$_2$O$_4$. The microscopic mechanism is discussed based on the symmetrically allowed magentoelastic coupling.
HST/WFPC2 proper motions in two bulge fields: kinematics and stellar population of the Galactic bulge

description: We report proper motion dispersions for stars in the direction of two fields of the Galactic bulge, using HST/WFPC2 images taken six years apart. Our two fields are Baade's Window (l,b)=(1.13,-3.77) and Sgr I (l,b)=(1.25 ,-2.65). Our proper motion dispersions are in good agreement with prior ground- and space-based proper motion studies in bulge fields, but in contrast to some prior studies, we do not exclude any subset of stars from our studies. In Baade's Window, we find the $l$ and $b$ proper motion dispersions are 2.9 and 2.5 mas/yr, while in Sgr I, they are 3.3 and 2.7 mas/yr, respectively. For the first time, we can clearly separate the foreground disk stars out from the bulge because of their large mean apparent proper motion. The population with non-disk kinematics (which we conclude to be the bulge) has an old main sequence turnoff point, similar to those found in old, metal rich bulge globular clusters while those stars selected to have disk kinematics lie on a fully populated main sequence. Separating main sequence stars by luminosity, we find strong evidence that the bulge population is rotating, largely explaining observations of proper motion anisotropy in bulge fields. Because we have isolated such a pure sample of stars in the bulge, we have one of the clearest demonstrations that the old stellar population of the inner bulge/bar is in fact rotating.

description: Poly(glycerol-sebacate) (PGS) is a biodegradable elastomer that is of interest in biomedical applications. While a porous format is common for tissue engineering, PGS degradation has been primarily studied in its nonporous format. This work investigates porous PGS degradation at three cure temperatures, resulting in materials with different mechanical and chemical properties that further influence degradation. Specimens exhibit varied structural degradation, ranging from limited loss of structure to complete loss. The thermal behaviors and mechanical properties also change during degradation, depending upon cure temperature. These observations can inform the choice of polymer processing methods for porous PGS applications.
Enumerating Independent Linear Inferences

Subjects: subject: Logic in Computer Science (cs.LO)
subject: FOS: Computer and information sciences

description: A linear inference is a valid inequality of Boolean algebra in which each variable occurs at most once on each side.

In this work we leverage recently developed graphical representations of linear formulae to build an implementation that is capable of more efficiently searching for switch-medial-independent inferences. We use it to find four `minimal' 8-variable independent inferences and also prove that no smaller ones exist; in contrast, a previous approach based directly on formulae reached computational limits already at 7 variables. Two of these new inferences derive some previously found independent linear inferences. The other two (which are dual) exhibit structure seemingly beyond the scope of previous approaches we are aware of; in particular, their existence contradicts a conjecture of Das and Strassburger.

We were also able to identify 10 minimal 9-variable linear inferences independent of all the aforementioned inferences, comprising 5 dual pairs, and present applications of our implementation to recent `graph logics'.

description: Recent neutron diffraction studies have yielded evidence that, in a particular cuprate family, holes doped into the CuO(2) planes segregate into stripes that separate antiferromagnetic domains. Here it is shown that such a picture provides a quantitatively consistent interpretation of the spin fluctuations measured by neutron scattering in La(1.85)Sr(0.15)CuO(4) and YBa(2)Cu(3)O(6+x).

Comments on entanglement entropy

Publisher: name: arXiv
Year: 1998
Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)
subject: FOS: Physical sciences

description: A new interpretation of entanglement entropy is proposed: entanglement entropy of a pure state with respect to a division of a Hilbert space into two subspaces 1 and 2 is an amount of information, which can be transmitted through 1 and 2 from a system interacting with 1 to another system interacting with 2. The transmission medium is quantum entanglement between 1 and 2. In order to support the interpretation, suggestive arguments are given: variational principles in entanglement thermodynamics and quantum teleportation. It is shown that a quantum state having maximal entanglement entropy plays an important role in quantum teleportation. Hence, the entanglement entropy is, in some sense, an index of efficiency of quantum teleportation. Finally, implications for the information loss problem and Hawking radiation are discussed.

description: Given a metric space $\mathcal{M}$ that contains at least two points, the chromatic number $χ\left(\mathbb{R}^n_{\infty}, \mathcal{M} \right)$ is defined as the minimum number of colours needed to colour all points of an $n$-dimensional space $\mathbb{R}^n_{\infty}$ with the max-norm such that no isometric copy of $\mathcal{M}$ is monochromatic. The last two authors have recently shown that the value $χ\left(\mathbb{R}^n_{\infty}, \mathcal{M} \right)$ grows exponentially for all finite $\mathcal{M}$. In the present paper we refine this result by giving the exact value $χ_{\mathcal{M}}$ such that $χ\left(\mathbb{R}^n_{\infty}, \mathcal{M} \right) = (χ_{\mathcal{M}}+o(1))^n$ for all 'one-dimensional' $\mathcal{M}$ and for some of their Cartesian products. We also study this question for infinite $\mathcal{M}$. In particular, we construct an infinite $\mathcal{M}$ such that the chromatic number $χ\left(\mathbb{R}^n_{\infty}, \mathcal{M} \right)$ tends to infinity as $n \rightarrow \infty$.

Different Traces of Quantum Systems Having the Same Classical Limit

description: Many quantum systems may have the same classical limit. We argue that in the classical limit their traces do not necessarily converge one to another. The trace formula allows to express quantum traces by means of classical quantities as sums over periodic orbits of the classical system. To explain the lack of convergence of the traces we need the quantum corrections to the classical actions of periodic orbits. The four versions of the quantum baker map on the sphere serve as an illustration of this problem.

description: In relativistic heavy-ion collisions, properties of the initial state and effects arising during evolution of the medium, such as a transition between the hadronic and partonic phases, should reflect themselves in event-by-event fluctuations of the number of produced particles. In this paper, recent measurements of several event-by-event observables, namely, dynamical fluctuations of relative particle yields and forward-backward correlations of different types, are discussed. Also, new observables for forward-backward correlation studies are proposed: correlations between ratios of identified particle yields in two separated acceptance intervals and the correlation between the ratio in one interval and average transverse momentum in another.

description: The bivariate chromatic polynomial $χ_G(x,y)$ of a graph $G = (V, E)$, introduced by Dohmen-Pönitz-Tittmann (2003), counts all $x$-colorings of $G$ such that adjacent vertices get different colors if they are $\le y$. We extend this notion to mixed graphs, which have both directed and undirected edges. Our main result is a decomposition formula which expresses $χ_G(x,y)$ as a sum of bivariate order polynomials (Beck-Farahmand-Karunaratne-Zuniga Ruiz 2020), and a combinatorial reciprocity theorem for $χ_G(x,y)$.

description: We present a compact atomic clock using cold rubidium atoms based on an isotropic light cooling, a Ramsey microwave interrogation and an absorption detection. Its technology readiness level is suitable to industrial transfer. We use a fibre optical bench, based on a frequency-doubled telecom laser. The isotropic light cooling technique allows us to cool down the atoms in 100 ms and works with a cycle time around 200 ms. We carried out measurements in simulated microgravity and obtained the narrowest fringes ever recorded in microgravity.
