We numerically solve the fully nonlinear hydrodynamic equations of motion and observe the excitation and decay of the analog BTZ quasinormal modes in the process. We consider both a small perturbation in the steady state configuration of the fluid and a large perturbation; the latter could be regarded as an example of formation of the analog (acoustic) BTZ black hole.

description: Quantum entanglement has multiple applications in quantum information processing. Developing methods to generate highly entangled states independent of initial conditions is an essential task. Herein we aim to generate highly entangled states via discrete-time quantum walks. We propose deterministic Parrondo sequences that generate states that are generally much more entangled than states produced by sequences using only one of the two coins. We show that some Parrondo sequences generate highly entangled states, which are independent of the phase of the initial state used and further lead to maximally entangled states in some cases. We study Parrondo sequences for a small number of time steps and the asymptotic limit of a large number of time steps.

description: The Katz-Klemm-Vafa conjecture expresses the Gromov-Witten theory of K3 surfaces (and K3-fibred 3-folds in fibre classes) in terms of modular forms. Its recent proof gives the first non-toric geometry in dimension greater than 1 where Gromov-Witten theory is exactly solved in all genera. We survey the various steps in the proof. The MNOP correspondence and a new Pairs/Noether-Lefschetz correspondence for K3-fibred 3-folds transform the Gromov-Witten problem into a calculation of the full stable pairs theory of a local K3-fibred 3-fold. The stable pairs calculation is then carried out via degeneration, localisation, vanishing results, and new multiple cover formulae.

description: Introduction:

Difference B/W Climbers & Creepers:- 

Climbers: Climbers have a very thin, long and weak stem which cannot stand upright, but they can use external support to grow vertically and carry their weight. Ex. pea plant, grapevine, sweet gourd, money plant, jasmine…..etc.

Creepers: Creepers, as the name suggests, are plants  that creep on the ground. They have very fragile, long, thin stems that can neither stand erect nor support all its weight. Ex. Watermelon, strawberry, pumpkin and sweet potatoes….etc.

Climbing Habitat:

Due to rapid growth but suppressed lateral growth and elongated axes, climbers possess very weak and flexible stem, they need rocks or any other man-made structures for support.

Distribution:

Climbing plants are found in all kinds of forests and all over the world.

The evidences of climber dominance in certain  forest ecosystems i.e. temperate and tropical.

description: Holey graphyne (HGY) is a recently synthesized two-dimensional semiconducting allotrope of carbon composed of a regular pattern of six and eight-vertex carbon rings. In this study, based on first-principles density functional theory and molecular dynamics simulations, we predict a similar stable porous boron nitride holey graphyne-like structure that we call BN-holey-graphyne (BN-HGY). The dynamical and thermal stability of the structure at room temperature is confirmed by performing calculations of the phonon dispersion relations, and also ab-initio molecular dynamics simulations. BN-HGY structure has a wide direct bandgap of 5.18 eV, which can be controllably tuned by substituting carbon, aluminum, silicon, and phosphorus atom in place of sp and sp$^2$ hybridized boron and nitrogen atoms of BN-HGY. We have also calculated the optical properties of the HGY and BN-HGY structures for the first time and found that the optical absorption spectra of these structures span full visible and a wide range of ultraviolet regions. We have found that the Gibbs free energy of the BN-HGY structure for the hydrogen adsorption process is very close to zero (-0.04 eV) and, therefore, the BN-HGY structure can be utilized as a potential catalyst for HER. Therefore, we propose that the boron nitride analog of holey graphyne can be synthesized and that it has a wide range of applications in nanoelectronics, optoelectronics, spintronics, ultraviolet laser, and solar cell devices.

description: Designing agents, capable of learning autonomously a wide range of skills is critical in order to increase the scope of reinforcement learning. It will both increase the diversity of learned skills and reduce the burden of manually designing reward functions for each skill. Self-supervised agents, setting their own goals, and trying to maximize the diversity of those goals have shown great promise towards this end. However, a currently known limitation of agents trying to maximize the diversity of sampled goals is that they tend to get attracted to noise or more generally to parts of the environments that cannot be controlled (distractors). When agents have access to predefined goal features or expert knowledge, absolute Learning Progress (ALP) provides a way to distinguish between regions that can be controlled and those that cannot. However, those methods often fall short when the agents are only provided with raw sensory inputs such as images. In this work we extend those concepts to unsupervised image-based goal exploration. We propose a framework that allows agents to autonomously identify and ignore noisy distracting regions while searching for novelty in the learnable regions to both improve overall performance and avoid catastrophic forgetting. Our framework can be combined with any state-of-the-art novelty seeking goal exploration approaches. We construct a rich 3D image based environment with distractors. Experiments on this environment show that agents using our framework successfully identify interesting regions of the environment, resulting in drastically improved performances.

description: A unique characteristic of enzymes in Nature is the ability to respond to changing environments and adapt how fast they perform their function. If chemists can design complexes which synthesize chemicals in the same way, we can improve efficiency, save energy, and reduce waste. This kind of chemistry is called cation-controlled catalysis, and we studied its function in a kind of reactivity called hydroamination: compared to a control complex, a crown-ether containing nickel catalyst exhibited switchable catalysis of crotonitrile hydroamination with morpholine. Thermodynamic studies further advanced our understanding of substrate gating in cation controlled catalysis.

description: Observing the CKM matrix elements written in different parametrization schemes, one can notice obvious relations among the sine-values of the CP phases in those schemes. Using the relations, we establish a few parametrization-independent equations, by which the matrix elements of the CKM matrix can be completely fixed up to a universal parameter. If it is true, we expect that there should exist a hidden symmetry in the nature which determines the relations. Moreover, it requires a universal parameter, naturally it would be the famous Jarlskog invariant which is also parametrization independent. Thus the four parameters (three mixing angles and one CP phase) of the CKM matrix are not free, but determined by the symmetry and the universal parameter. As we generalize the rules to the PMNS matrix for neutrino mixing, the CP phase of the lepton sector is predicted to be within a range of $0\sim 59^\circ$ centered at $39^\circ$ (in the P$_a$ parametrization) which will be tested in the future experiments.

description: Screen time has been associated with overweight and obesity, as well as with poorer dietary quality. However, the reasons explaining these associations are not well understood. The objectives of this cross-sectional study were [1] to determine the extent of overall TV viewing as well as using screens while eating (e.g., watching TV or using a tablet), [2] to compare food and nutrient consumption of on-versus off-screen eating occasions, and [3] to determine whether TV viewing and using screens while eating is associated with overall dietary intake. Participants were from the Food Environment Chilean Cohort (n = 938, 4–6 y) and the Growth and Obesity Cohort Study (n = 752, 12–14 y). Dietary data was collected via one 24-h food recall. For each eating occasion, activity performed during consumption (e.g., watching TV, playing sports) was reported. Weekly TV viewing time was collected via an additional survey instrument. Analyses included multivariable linear and logistic regression. Post-hoc pairwise comparisons examined differences in outcomes by tertiles. Our sample reported a median of 9–13.5 weekly hours of TV viewing and 87.5% reported consuming at least one meal or snack per day while using screens. The median kilocalories contributed by eating during screen use was 387 kcal/d in children and 848 kcal/day in adolescents, which represents 34.7% and 42.3% of daily energy intake, respectively. There were no consistent differences when comparing eating occasions consumed on-screen versus off-screen. Higher weekly TV viewing was associated with elements of a less healthy diet including more sweets and desserts in children, and more sugar sweetened beverages in adolescents. A large percentage of Chilean children and adolescents’ daily energy is consumed while using screens. In depth, longitudinal work is needed to understand how screen time eating affects diet quality and nutritional status.

Towards obtaining a 3-Decomposition from a perfect Matching

description: A decomposition of a graph is a set of subgraphs whose edges partition those of $G$. The 3-decomposition conjecture posed by Hoffmann-Ostenhof in 2011 states that every connected cubic graph can be decomposed into a spanning tree, a 2-regular subgraph, and a matching. It has been settled for special classes of graphs, one of the first results being for Hamiltonian graphs. In the past two years several new results have been obtained, adding the classes of plane, claw-free, and 3-connected tree-width 3 graphs to the list. In this paper, we regard a natural extension of Hamiltonian graphs: removing a Hamiltonian cycle from a cubic graph leaves a perfect matching. Conversely, removing a perfect matching $M$ from a cubic graph $G$ leaves a disjoint union of cycles. Contracting these cycles yields a new graph $G_M$. The graph $G$ is star-like if $G_M$ is a star for some perfect matching $M$, making Hamiltonian graphs star-like. We extend the technique used to prove that Hamiltonian graphs satisfy the 3-decomposition conjecture to show that 3-connected star-like graphs satisfy it as well.

description: We examine how the ability of a system to redundantly proliferate relevant information about its pointer states is affected when it is coupled to multiple baths. To this end, we consider a system in contact with two baths: one -- termed the {\it accessible} environment -- which, on its own, induces a pure dephasing mechanism on the state of the system and satisfies the conditions for classical objectivity to be established. The second environment, which we dub as {\it inaccessible}, affects the system in two physically relevant ways. Firstly, we consider an interaction that commutes with the Hamiltonian describing the interaction between system and accessible bath. It thus also gives rise to dephasing of the system, albeit on different time scales. Secondly, we consider a thermalising interaction, which does not commute with the system-accessible environment Hamiltonian. While the former still allows the system to redundantly encode its state into the accessible environment, the latter degrades the correlations, eventually destroying them in the long-time limit, and thus leads to a loss of the conditions necessary for classical objectivity to be established. This sheds light on the role that commutativity between the various system-bath interaction terms plays when establishing the conditions for classical objectivity to be supported.

description: We develop theory for a two-component miscible dipolar condensate in a planar trap. Using numerical solutions and a variational theory we solve for the excitation spectrum and identify regimes where density- and spin-roton excitations are favored. We characterize the various instabilities that can emerge in this system over a wide parameter regime and present results for the stability phase diagram. Importantly this allows us to identify the parameter regimes where a novel roton-immiscibility transition can occur, driven by the softening of the spin roton excitation.

description: We propose a cavity-Heisenberg spin chain (CHS) quantum battery (QB) with the long-range interactions and investigate its charging process. The performance of the CHS QB is substantially improved compared to the Heisenberg spin chain (HS) QB. When the number of spins $N \gg 1$, the quantum advantage $α$ of the QB's maximum charging power can be obtained, which approximately satisfies a superlinear scaling relation $P_{max} \propto N^α$. For the CHS QB, $α$ can reach and even exceed $1.5$, while the HS QB can only reach about $α=0.75$. We find that the maximum stored energy of the CHS QB has a critical phenomenon. By analyzing the Wigner function, von Neumann entropy, and logarithmic negativity, we demonstrate that entanglement can be a necessary ingredient for QB to store more energy, but not sufficient.

description: The surprising expense of fish feeds is the most concerning issue in the growth of Genetically Improved Tilapia brought about by the protein from the costly fish feed. Searching for an alternative and inexpensive fish feed is the aim of the study. The study determined the growth and survival rates of the Genetically Improved Farmed Tilapia (GIFT) in the HAPA using formulated sweet potato granules and commercial feeds as basis for the formulation of a Technology Guide. The experiment method was used in the study. The findings showed that the three formulated feeds have lower protein (20.33, 19.3, 19.6) yet with higher fat (24.1, 15.69, 10.72) than the commercial (24.1%, 3%). The initial and final weight in grams, length in centimeters and width in centimeters were highest on T1 then followed by T2 and T3. It was with the use of T1 which proved to be an effective feed. Moreover, the ingredients utilized in the feed formulations are possible for the substitution of fish feed and the advancement of its usage is commendable.

description: Chordal structure and bounded treewidth allow for efficient computation in numerical linear algebra, graphical models, constraint satisfaction and many other areas. In this paper, we begin the study of how to exploit chordal structure in computational algebraic geometry, and in particular, for solving polynomial systems. The structure of a system of polynomial equations can be described in terms of a graph. By carefully exploiting the properties of this graph (in particular, its chordal completions), more efficient algorithms can be developed. To this end, we develop a new technique, which we refer to as chordal elimination, that relies on elimination theory and Gröbner bases. By maintaining graph structure throughout the process, chordal elimination can outperform standard Gröbner basis algorithms in many cases. The reason is that all computations are done on "smaller" rings, of size equal to the treewidth of the graph. In particular, for a restricted class of ideals, the computational complexity is linear in the number of variables. Chordal structure arises in many relevant applications. We demonstrate the suitability of our methods in examples from graph colorings, cryptography, sensor localization and differential equations.

description: Macroautophagy/autophagy is a conserved catabolic recycling pathway involving the sequestration of cytoplasmic components within double-membrane vesicles termed autophagosomes. The autophagy-related (Atg) protein Atg13 is a key member of the autophagy initiation complex. The Atg13 C terminus is an intrinsically disordered region (IDR) harboring a binding site for the vacuolar membrane protein Vac8. Recent reports suggest Atg13 acts as a hub to assemble the initiation complex, and also participates in membrane recognition. Here we show that the Atg13 C terminus directly binds to lipid membranes via electrostatic interactions between positively charged residues in Atg13 and negatively charged phospholipids as well as a hydrophobic insertion of a Phe residue. We identified 2 sets of residues in the Atg13 IDR that affect its phospholipid-binding properties; these residues overlap with the Vac8-binding domain of Atg13. Our data indicate that Atg13 binding to phospholipids and Vac8 is mutually exclusive, and both are required for efficient autophagy.

We take for granted the widespread judgment by mathematical logicians that Gödel's incompleteness theorem is deep, and focus on the philosophical question of what its depth consists in. We focus on the methodological study of the depth of Gödel's incompleteness theorem, and propose three criteria to account for its depth: influence, fruitfulness, and unity. Finally, we give some explanations for our account of the depth of Gödel's incompleteness theorem.

description: Purpose: Previous studies that addressed whether left ventricular hypertrophy is more closely associated with central than peripheral blood pressure (BP) have been inconsistent. Radial artery wave generated by applanation tonometry and calibrated with brachial BP in 162 adult Nigerians were analysed by using generalized transfer function to derive central BP. Materials and methods: We compared the associations of ECG voltages and left ventricular hypertrophy (ECG-LVH) as continuous and binary variables respectively with central and brachial BP indices. Results: In a multivariable adjusted analysis, 1 standard deviation (SD) increase in brachial systolic, diastolic, pulse and mean arterial pressures increased the Sokolow–Lyon QRS voltage by 0.34 (CI, 0.21–0.48; p p p p > 0.05) corresponding Sokolow–Lyon QRS increase of 0.26 (0.12–0.40, p p p p p p p p > 0.05) corresponding OR of 2.41 (1.33–4.36, p p p Conclusion: Central and peripheral BP are similarly associated with Sokolow–Lyon ECG voltage and hypertrophy.

description: We study an asymmetric dark matter model with self-interacting dark matter consisting of a Dirac fermion $χ$ coupled to a scalar or vector mediator, such that the reaction $χ+ χ\to χ+ χ$ is well described by perturbation theory. We compute the scattering cross section $σ$, the transfer cross section $σ_T$, and the viscosity cross section $σ_V$ for this reaction. As one part of our study, we give analytic and numerical comparisons of results obtained with the inclusion of both $t$-channel and $u$-channel exchanges and results obtained in an approximation that has often been used in the literature that includes only the $t$-channel contribution. The velocity dependences of these cross sections are studied in detail and shown to be in accord with observational data.

description: This data set contains the catalogue of Earth Auroral Kilometric Radiations (AKR) identified in the Polar/PWI observations. The format of this catalogue follows the TFCat specifications (Time-Frequency Catalogue, https://gitlab.obspm.fr/maser/catalogues/tfcat/-/tree/master/). The two gifs provided show the Polar satellite trajectories over the catalogue period, i.e. ∼ 60 orbits from 1996 March 25th to 1996
 May 9th, relative to the Earth. The colour of the orbit is the integrated intensity of all labeled emission (excluding “LFE”) across
 all frequencies measured by the PWI instrument (see Table 1 for more details on the labeled features). Two different coordinates systems are used here: The Geocentric Solar Magnetospheric (GSM) system in units of Earth radii, where x is positive sunward, y is defined to be perpendicular to the Earth’s magnetic dipole, and z is positive northward. The Geomagnetic (GM) coordinate system in units of Earth radii, where Z-axis points to the Geomagnetic north pole, X-axis is in the Earth’s magnetic equatorial plane but is fixed with the rotation of the Earth, and Y-axis completes the triad. The ephemeris used to produce these plots are accessible at https://doi.org/10.5281/zenodo.7589412. The magnetic field model used to compute the ephemeris is the International Geomagnetic Reference Field (IGRF) model version 13.

description: We study the spectral and transport properties of a Mott insulator driven by a static electric field into a non-equilibrium steady state. For the dissipation, we consider two mechanisms: Wide-band fermion reservoirs and phonons included within the Migdal approximation. The electron correlations are treated via non-equilibrium dynamical mean field theory with an impurity solver suitable for strong correlations. We find that dissipation via phonons is limited to restricted ranges of field values around Wannier-Stark resonances. To cover the full range of field strengths, we allow for a small coupling with fermionic baths, which stabilizes the solution. When considering both dissipation mechanisms, we find that phonons enhance the current for field strengths close to half of the gap while lowering it at the gap resonance as compared to the purely electronic dissipation used by Murakami and Werner [arXiv:1804.08257]. Once phonons are the only dissipation mechanism, the current in the metallic phase is almost one order of magnitude smaller than the typical values obtained by coupling to a fermionic bath. In this case, the transport regime is characterized by an accumulation of charge in the upper Hubbard band described by two effective chemical potentials.

description: The manifold hypothesis is a core mechanism behind the success of deep learning, so understanding the intrinsic manifold structure of image data is central to studying how neural networks learn from the data. Intrinsic dataset manifolds and their relationship to learning difficulty have recently begun to be studied for the common domain of natural images, but little such research has been attempted for radiological images. We address this here. First, we compare the intrinsic manifold dimensionality of radiological and natural images. We also investigate the relationship between intrinsic dimensionality and generalization ability over a wide range of datasets. Our analysis shows that natural image datasets generally have a higher number of intrinsic dimensions than radiological images. However, the relationship between generalization ability and intrinsic dimensionality is much stronger for medical images, which could be explained as radiological images having intrinsic features that are more difficult to learn. These results give a more principled underpinning for the intuition that radiological images can be more challenging to apply deep learning to than natural image datasets common to machine learning research. We believe rather than directly applying models developed for natural images to the radiological imaging domain, more care should be taken to developing architectures and algorithms that are more tailored to the specific characteristics of this domain. The research shown in our paper, demonstrating these characteristics and the differences from natural images, is an important first step in this direction.

title: Der Einfluss von Infrastrukturmaßnahmen auf (unzerschnittene) Lebensräume: Untersuchungen zu Raumnutzung, Wildunfällen, Frequentierung von Querungsmöglichkeiten, Wildtiermanagement und Optimierungsmöglichkeiten der Habitatstruktur im Bereich der Bundesautobahn 4 südöstlich von Erfurt

description: Das Untersuchungsgebiet ist die BAB 4 südöstlich von Erfurt. Die Thesis versucht zu erörtern, welches Spannungsfeld zwischen Wildtieren, Infrastruktur und dem Menschen zwischen Autobahn-km 205 und 213,5 vorliegt. Methodische Grundlage ist der Blick auf den Landschaftswandel in Bezug auf den Bau und Ausbau der Autobahn, ein Fotofallenmonitoring und die Analyse von Wildunfalldaten und A&E-Flächen, sowie das Experteninterview. Es wird deutlich, dass die Autobahn eine erhebliche Zerschneidungs- und Trennwirkung hervorruft. Eine Vielzahl von Wildtieren hat sich an die veränderte Landschaft angepasst und nutzt den Bereich nahe der Autobahn rege. Die Jagdausübung wird durch die sich darstellende Situation größtenteils erschwert. Bestehende Unterführungen der Autobahn werden ausschließlich vom Raubwild zur Querung dieser genutzt. Eine Reihe von A&E-Flächen säumt das Projektgebiet, die einzelnen Maßnahmen sind aber unmittelbar am ungezäunten Straßenkörper und damit von zweifelhafter Wirkung. Lösungsansatz kann hier im ersten Schritt nur die Zäunung der Autobahn sein. Weitere Schritte, wie eine angepasste Querungshilfe für alle Wildarten, sollte in Erwägung gezogen werden. Die vorliegende Thesis möchte hierfür einen ersten Impuls liefern.
Relations between global forcing number and maximum anti-forcing number of a graph

description: The global forcing number of a graph G is the minimal cardinality of an edge subset discriminating all perfect matchings of G, denoted by gf(G). For any perfect matching M of G, the minimal cardinality of an edge subset S in E(G)-M such that G-S has a unique perfect matching is called the anti-forcing number of M,denoted by af(G, M). The maximum anti-forcing number of G among all perfect matchings is denoted by Af(G). It is known that the maximum anti-forcing number of a hexagonal system equals the famous Fries number. We are interested in some comparisons between the global forcing number and the maximum anti-forcing number of a graph. For a bipartite graph G, we show that gf(G)is larger than or equal to Af(G). Next we mainly extend such result to non-bipartite graphs, which is the set of all graphs with a perfect matching which contain no two disjoint odd cycles such that their deletion results in a subgraph with a perfect matching. For any such graph G, we also have gf(G) is larger than or equal to Af(G) by revealing further property of non-bipartite graphs with a unique perfect matching. As a consequence, this relation also holds for the graphs whose perfect matching polytopes consist of non-negative 1-regular vectors. In particular, for a brick G, de Carvalho, Lucchesi and Murty [4] showed that G satisfying the above condition if and only if G is solid, and if and only if its perfect matching polytope consists of non-negative 1-regular vectors. Finally, we obtain tight upper and lower bounds on gf(G)-Af(G). For a connected bipartite graph G with 2n vertices, we have that 0 \leq gf(G)-Af(G) \leq 1/2 (n-1)(n-2); For non-bipartite case, -1/2 (n^2-n-2) \leq gf(G)-Af(G) \leq (n-1)(n-2).

description: Background: The potential misapplication of current opioid prescribing policies remains understudied and may have substantial adverse implications for patient safety. Methods: We used autoregressive integrated moving average models to assess level and trend changes in monthly 1) prescribing rates, 2) days’ supply, and 3) daily morphine milligram equivalents (MME) of incident opioid prescriptions relative to 1) a state medical board initiative to reduce high-dose and -volume opioid prescribing and 2) legislation to limit initial opioid prescriptions for acute and postsurgical pain. We examined outcomes by pain indication overall and by cancer history, using prescribing patterns for benzodiazepines to control for temporal trends. We used large private health insurance claims data to include North Carolina residents, aged 18–64, insured at any point between January 2012 and August 2018. Results: After the medical board initiative, prescribing patterns for chronic pain patients did not change; conversely, acute and postsurgical pain patients experienced immediate declines in daily MME. Post-legislation prescription rates did not decline for those with acute, postsurgical, and non-cancer pain, but instead declined among cancer patients with chronic pain. Chronic pain patients experienced the largest days’ supply declines post-legislation, instead of acute and postsurgical pain patients. Conclusions: We found mixed evidence on the potential impact of two opioid prescribing policies, with some observed declines in a group not intended to be impacted by the policy. This study provides evidence of the need for clearer opioid prescribing policies to ensure impacts on intended populations and avoid unintended consequences.

description: We consider a general choice of integration constants in the resolution of the dynamical equations derived from a recently proposed effective model that describes black hole spacetimes in the context of loop quantum cosmology. The interest of our analysis is twofold. On the one hand, it allows for a study of the entire space of solutions of the model, which is absent in the literature and is fundamental for understanding the relation with any underlying quantum theory. On the other hand, choices of integration constants that generalize the type of solutions considered so far may lead to exotic behaviors in the effective black hole geometry, as well as modified thermodynamical properties. With these motivations in mind, we discuss the interior and exterior geometries, and present the conditions that a satisfactory matching at the horizons imposes. Then, we turn our attention to the Hawking temperature associated with the black horizon of the model, which we find to be affected by the freedom of choice of integration constants. Finally, we briefly comment on the asymptotic structure of the general solution and compare different notions of mass.
