description: We estimated the population size of the Secretarybird in the Serengeti National Park and identified ecological factors characterizing the high-density areas, which should be established as high-priority conservation zones. To estimate the abundance and density of Secretarybird within the Serengeti National Park (SNP) and investigate environmental variables driving its abundance. In 2023, Secretarybirds were counted along 52 transects (average length = 15.3 ± 1.8 km), replicated at least three times outside of the breeding season. Twelve transects with the most observations were repeated up to eight times. Abundance and density were estimated through multiple-covariate distance sampling, while habitat selection was assessed using generalized additive mixed models and generalized linear models. We estimated an average density of 1.3 Secretarybirds/10 km2 and an abundance of 1,513.3 individuals. Areas of highest density averaged 2.3 Secretarybirds/10 km2 and 622.5 individuals. The greatest abundances occurred in transition zones between extensive grassland with high vegetation cover and habitats characterized by open woodlands or treed shrublands. Secretarybirds preferred flat environments with relatively more seasonal rivers and an annual precipitation of < 900 mm. Abundance decreased in grasslands with low vegetation cover and where open grassed woodland coverage was >20%. The probability of spotting single individuals versus pairs was higher in the western and central SNP and in more heterogeneous habitats with greater coverage of open grassed woodland and dense treed grassland. Closed treed shrublands were preferred by pairs. Secretarybird abundance was lower where the proportion of habitat burned for prescribed fires exceeded 60%. These results for the Secretarybird’s demography and ecology in the Serengeti ecosystem are essential for a long-term monitoring programme and conservation actions in Tanzania.

description: Networks of quantum devices with coherent control over their configuration offer promising advantages in quantum information processing. So far, the investigation of these advantages assumed that the control system was initially uncorrelated with the data processed by the network. Here, we explore the power of quantum correlations between data and control, showing two communication tasks that can be accomplished with information-erasing channels if and only if the sender shares prior entanglement with a third party (the ``controller'') controlling the network configuration. The first task is to transmit classical messages without leaking information to the controller. The second task is to establish bipartite entanglement with a receiver, or, more generally, to establish multipartite entanglement with a number of spatially separated receivers.

description: It is shown that the Hartle-Hawking state of a scalar field is a maximum of entanglement entropy in the space of pure quantum states satisfying the condition that backreaction is finite. In other words, the Hartle-Hawking state is a curved-space analogue of the EPR state, which is also a maximum of entanglement entropy.

description: Predicting the next interaction of a short-term interaction session is a challenging task in session-based recommendation. Almost all existing works rely on item transition patterns, and neglect the impact of user historical sessions while modeling user preference, which often leads to non-personalized recommendation. Additionally, existing personalized session-based recommenders capture user preference only based on the sessions of the current user, but ignore the useful item-transition patterns from other user's historical sessions. To address these issues, we propose a novel Heterogeneous Global Graph Neural Networks (HG-GNN) to exploit the item transitions over all sessions in a subtle manner for better inferring user preference from the current and historical sessions. To effectively exploit the item transitions over all sessions from users, we propose a novel heterogeneous global graph that contains item transitions of sessions, user-item interactions and global co-occurrence items. Moreover, to capture user preference from sessions comprehensively, we propose to learn two levels of user representations from the global graph via two graph augmented preference encoders. Specifically, we design a novel heterogeneous graph neural network (HGNN) on the heterogeneous global graph to learn the long-term user preference and item representations with rich semantics. Based on the HGNN, we propose the Current Preference Encoder and the Historical Preference Encoder to capture the different levels of user preference from the current and historical sessions, respectively. To achieve personalized recommendation, we integrate the representations of the user current preference and historical interests to generate the final user preference representation. Extensive experimental results on three real-world datasets show that our model outperforms other state-of-the-art methods.

description: We study viscous fingering of an air-nematic interface in a radial Hele-Shaw cell when periodically switching on and off an electric field, which reorients the nematic and thus changes its viscosity, as well as the surface tension and its anisotropy (mainly enforced by a single groove in the cell). We observe undulations at the sides of the fingers which correlate with the switching frequency and with tip oscillations which give maximal velocity to smallest curvatures. These lateral undulations appear to be decoupled from spontaneous (noise-induced) side branching. We conclude that the lateral undulations are generated by successive relaxations between two limiting finger widths. The change between these two selected pattern scales is mainly due to the change in the anisotropy. This scenario is confirmed by numerical simulations in the channel geometry, using a phase-field model for anisotropic viscous fingering.

description: Rota-Baxter algebras and the closely related dendriform algebras have important physics applications, especially to renormalization of quantum field theory. Braided structures provide effective ways of quantization such as for quantum groups. Continuing recent study relating the two structures, this paper considers Rota-Baxter algebras and dendriform algebras in the braided contexts. Applying the quantum shuffle and quantum quasi-shuffle products, we construct free objects in the categories of braided Rota-Baxter algebras and braided dendriform algebras, under the commutativity condition. We further generalize the notion of dendriform Hopf algebras to the braided context and show that quantum shuffle algebra gives a braided dendriform Hopf algebra. Enveloping braided commutative Rota-Baxter algebras of braided commutative dendriform algebras are obtained.

description: A phytochemical investigation on the stems of Glycosmis puberula var. craibii led to the isolation of a new indole alkaloid (named glycosmiscrol A, 1), together with four known compounds (2–5). The new structure was elucidated by detailed analysis of comprehensive spectroscopic methods. All isolated compounds were evaluated for their antiproliferative activities against five human cancer cell lines: HL-60, SMMC-7721, A-549, MCF-7 and SW480 in vitro. Compounds 1–5 showed significant antiproliferative effects with IC50 values ranging from 0.16 to 8.58 µM.
Spectral and timing analysis of the bursting pulsar GRO J1744-28 with RXTE observations

description: We analyzed RXTE/PCA observations of the bursting pulsar GRO J1744-28 during its two outbursts in 1995-1997. We have found a significant transition, i.e., a sharp change, of both spectral and timing properties around a flux of $\rm 10^{-8}\ ergs\ cm^{-2}\ s^{-1}$ (3-30 keV), which corresponds to a luminosity of 2--8$\rm \times 10^{37}\ ergs\ s^{-1}$ for a distance of 4--8 kpc. We define the faint (bright) state when the flux is smaller (larger) than this threshold. In the faint state, the spectral hardness increases significantly with the increasing flux, while remaining almost constant in the bright state. In addition, we find that the pulsed fraction is positively related to both the flux and the energy (<30keV) in both states. Thanks to the very stable pulse profile shape in all energy bands, a hard X-ray lag could be measured. This lag is only significant in the faint state (reaching $\sim$ 20\,ms between 3-4 keV and 16-20 keV), and much smaller in the bright state ($\lesssim$2ms). We speculate that the discovered transition might be caused by changes of the accretion structure on the surface of the neutron star, and the hard X-ray lags are due to a geometry effect.

description: The advancement in capabilities enabled by handheld devices and the prospective internet of things has led to an explosion of wireless data consumption in the last decade. The ever-increasing demand for high speed data transfer has projected the unprecedented importance of terahertz spectral range for next generation wireless communication systems. However, versatile interaction and active manipulation of terahertz waves required for a wide-range of terahertz technologies are either unavailable or unscalable. Here, we report on an integrated platform of chalcogenide phase change material, germanium antimony telluride (GST), with metamaterials for multidimensional manipulation of terahertz waves. The thermal, electrical and optical stimulation of GST provide multilevel non-volatility, sub-wavelength spatial selectivity and variable ultrafast switching of terahertz waves, respectively. These multifaceted response of phase change material can be used in tandem with metamaterial that enables strong field confinement along with on-demand spectral response and frequency selectivity. The unique and multifarious properties of GST combined with the versatility and scalability of metamaterial design and ease of fabrication could aid in the development of advanced devices operating in terahertz range, such as spatio-temporal light modulators, neuromorphic photonic devices, compressive imagers, and switchable holograms, vital for the next generation wireless communication systems.

description: News warning about climate risks has not typically included information about how society can respond, but journalism about credible efforts to address climate change is becoming more prevalent. To understand how news employing this emerging approach is framed we undertook an inductive quantitative content analysis of climate solutions journalism. Cluster analysis of 244 text-based climate solutions news stories published in U.S.-based outlets resulted in three previously undescribed news frames. The most prevalent frame (88%) focuses on adaptation over mitigation with little mention of causes, while stories emblematic of the second-most prevalent frame featured responses led by people typically drawing on place-based identity and working cooperatively beyond partisanship. The least prevalent frame emphasizes mitigation and who is morally responsible. Findings contribute to framing theory as well as offer practical implications for journalists seeking to engage news audiences about this critical issue.

description: In the past years trend of microgrids is increasing very fast to reduce peak-hour costs. However, in these systems, third parties are still involved in selling surplus energy. This results in increased cost of energy and there are many operational and security barriers in such systems. These issues can be solved by the decentralized distributed system of microgrids where a consumer can locally sell their surplus energy to another consumer. To deploy such a system, one must consider security barriers for the transaction of energy. This paper proposes a solution to these problems by devising a scheme as a marketplace where users interact with each other to buy and sell energy at better rates and get energy-generating resources on lease so that users do not have to worry about capital investment. Agreement between owner of resources and consumer is recorded on blockchain based smart contracts. In this paper, a survey is performed for existing well known, decentralized energy solutions. This paper also proposes an extra layer of security to leverage a shielded execution environment so that information of energy generated, utilized, and shared cannot be changed by consumers and third parties even if the system is compromised.

This implies the original conjecture up to isogeny. If the degree of cohomology is at most two, we can prove the conjecture for the Hodge realization without isogeny, and even for 1-motives with torsion.

The Physical Interpretation of the Lanczos Tensor

Publisher: name: arXiv
Year: 1999
Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)
subject: FOS: Physical sciences

description: The field equations of general relativity can be written as first order differential equations in the Weyl tensor, the Weyl tensor in turn can be written as a first order differential equation in a three index tensor called the Lanczos tensor. The Lanczos tensor plays a similar role in general relativity to that of the vector potential in electro-magnetic theory. The Aharonov-Bohm effect shows that when quantum mechanics is applied to electro-magnetic theory the vector potential is dynamically significant, even when the electro-magnetic field tensor $F_{ab}$ vanishes. Here it is assumed that in the quantum realm the Lanczos tensor is dynamically significant, and this leads to an attempt to quantize the gravitational field by pursuing the analogy between the vector field and the Lanczos tensor.

description: Chemical composition, in vitro antioxidant, DNA damage protective, nitrite scavenging activities, as well as antibacterial activity of Amomum kravanh fruits essential oil against several foodborne pathogens, were investigated. Results showed that the 1,8-cineole (58.53%) was found as the main component, followed by α-pinene (8.32%), α-terpinyl acetate (4.68%), α-terpinolene (4.12%), α-terpinene (3.55%), β-pinene (3.49%). The essential oil had significant antioxidant activity, the protective effect against DNA damage, and nitrite scavenging activity. These biological activities were dose-dependent, increasing with the higher dosage in a certain concentration range. The essential oil exhibited antibacterial activity against four foodborne pathogens with the minimum inhibitory concentration (MIC) of 5–10 mg/mL and minimum bactericide concentration (MBC) of 10–20 mg/mL. The antibacterial effects of essential oil were greater against Gram-positive bacteria as compared to Gram-negative bacteria. These results suggested that essential oil could be available as a significant natural agent for prevention of food oxidation and spoilage.

The speckle pattern is shown to become unstable if the nonlinearity exceeds a threshold value. The instability is due to a feedback provided by the multiple scattering and manifests itself in spontaneous fluctuations of the scattered intensity. The development of instability is independent of the sign of nonlinearity.

description: Collision phenomena are ubiquitous and of importance in determining the microscopic structures and intermolecular interactions of atoms and molecules. The existing approaches are mostly based on atomic or molecular scatterings, which are hindered by the inconvenience of using ultra-high vacuum and low temperature systems. Here we demonstrate a new spin-noise spectroscopic approach by measuring optical polarization rotation noise of the probe light, which operates with simple apparatus and ambient conditions. Our approach features tens of gigahertz bandwidth and one part-per-million resolution, outperforming existing spin-noise techniques. Enabled by the new technique, we observe the collision-induced spin noise of alkali atoms, and precisely determine key collision parameters, such as collision diameter, well depth, and dominant interaction type. Our work provides a new tool to study a broad range of collision phenomena under ambient conditions.

On the second law of thermodynamics: An ideal-gas flow spontaneously induced by a locally nonchaotic energy barrier

description: People are well aware that, inherently, certain small-scale nonchaotic particle movements are not governed by thermodynamics. Usually, such phenomena are studied by kinetic theory and their energy properties are considered "trivial". In current research, we show that, beyond the boundary of the second law of thermodynamics where Boltzmann's H-theorem does not apply, there are also large-sized systems of nontrivial energy properties: when the system is isolated, entropy can decrease; from a single thermal reservoir, the system can absorb heat and produce useful work without any other effect. The key concept is local nonchaoticity, demonstrated by using a narrow energy barrier. The barrier width is much less than the nominal particle mean free path, so that inside the barrier, the particle-particle collisions are sparse and the particle trajectories tend to be locally nonchaotic. Across the barrier, the steady-state particle flux ratio is intrinsically in a non-Boltzmann form. With a step-ramp structure, the nonequilibrium effect spreads to the entire system, and a global flow is generated spontaneously from the random thermal motion. The deviation from thermodynamic equilibrium is steady and significant, and compatible with the basic principle of maximum entropy. These theoretical and numerical analyses may shed light on the fundamentals of thermodynamics and statistical mechanics.

description: By means of the first-principles calculations and magnetic topological quantum chemistry, we demonstrate that the low energy physics in the checkerboard antiferromagnetic (AFM) monolayer FeSe, very close to an AFM topological insulator that hosts robust edge states, can be well captured by a double-degenerate fragile topologically flat band just below the Fermi level. The Wilson loop calculations identify that such fragile topology is protected by the $S_{4z}$ symmetry, which gives rise to an AFM higher-order topological insulator that support the bound state with fractional charge $e/2$ at the sample corner. This is the first reported $S_{4z}$-protected fragile topological material, which provides a new platform to study the intriguing properties of magnetic fragile topological electronic states. Previous observations of the edge states and bound states in checkerboard AFM monolayer FeSe can also be well understood in our work.

During exercise in able-bodied subjects a redistribution of blood takes place to increase cardiac output and to supply the blood for exercising muscles. But in paraplegics, the impaired sympathetic innervation and lack of muscular pump disturb the redistribution of blood and diminish venous return (Hopman et al., 1992b). In upright arm activity particularly, venous return may be much poorer in paraplegic, than in able-bodied subjects. However, up to now the same indicators as in able-bodied subjects have been used for assessment of energy expenditure in paraplegics. The aim of this project was to assess the energy expenditure during arm crank ergometry and crutch walking in paraplegic and able-bodied subjects. The experiments can be divided into 4 phases i.e.: 1) assessment of energy expenditure during seated arm crank ergometry in 10 sports-active paraplegics and 20 able-bodied subjects 2) comparison of the effect of posture on the oxygen consumption, heart rate and perceived exertion in 7 sports-active paraplegics and 20 able-bodied subjects 3) A comparison of assessment of energy expenditure between sports and non-sports persons with spinal cord injury during arm crank ergometry 4) assessment of energy expenditure during crutch walking in 5 sports- active paraplegics and 10 able-bodied subjects.

description: In this work, we propose extremal black holes (BH) as critical points of a new class of gravitational collapses. The conjecture is made by observing the Continuous Self Similarity (CSS) and Discrete Self Similarity (DSS) behaviours of perturbations of an extremal black hole spacetime and compare them to similar properties of Choptuik-type critical solutions. By performing analytical perturbation studies on extremal black holes, we explicitly show that the DSS solution found here can be interpreted as renormalization group (RG) limit cycles, and the transition between CSS and DSS regimes occurs as the stable and unstable fixed points collide and move to the complex plane. We argue that the DSS solutions found in spherically symmetric gravitational collapses can be similarly interpreted. We identify various phenomena in non-gravitational systems with RG limit cycles, including DSS correlation function, DSS scaling laws in correlation length and order parameters, which are observed in gravitational critical collapses. We also discuss a version of gravitational Efimov effect.

description: A set of orthogonal states in multipartite systems is called to be locally stable if to preserving the orthogonality of the states, only trivial local measurement can be performed from each partite. Locally stable set of states are always locally indistinguishable yielding a form of nonlocality which is different from the Bell type nonlocality. In this work, we study the locally stable set of product states with small size. First, we give a lower bound on the size of locally stable set of product states. It is well known that unextendible product basis (UPB) is locally indistinguishable. But we find that some of them are not locally stable. On the other hand, there exists some small subset of minimum size UPB that are also locally stable which implies the nonlocality of such UPBs are stronger than other form.

description: We investigate the proximity effect in an s-wave superconductor/ferromagnetic metal with a Rashba spin-orbit coupling/diffusive normal metal junction and an s-wave superconductor/noncollinear magnetic metal/diffusive normal metal junction. We show the generation of equal spin-triplet pairings in the diffusive normal metal due to spin-flip scattering in the intermediate magnetic regions. The emergence of the spin-triplet odd-frequency Cooper pairings can generate a zero-energy peak in the quasiparticle density of states in the diffusive normal metal.

description: We define a new model of interface roughening which has the property that the minimum of interface height is conserved locally during the growth. This model corresponds to the limit $q \to \infty$ of the q-color dimer deposition-evaporation model introduced by us earlier [Hari Menon M K and Dhar D 1995 J. Phys. A: Math. Gen. 28 6517]. We present numerical evidence from Monte Carlo simulations and the exact diagonalization of the evolution operator on finite rings that this model is not in the universality class of the Kardar-Parisi-Zhang interface growth model. The dynamical exponent z in one dimension is larger than 2, with $z \approx 2.5$. And there are logarithmic corrections to the scaling of the gap with system size. Higher dimensional generalization of the model is briefly discussed.

subject: FOS: Physical sciences

description: The Einstein equations are integrated in the presence of two (incoming and outgoing) streams of null dust, under the assumptions of spherical symmetry and staticity. The solution is also written in double null and radiation coordinates and it is reinterpreted as an anisotropic fluid. Interior matching with a static fluid and exterior matching with the Vaidya solution along null hypersurfaces is discussed. The connection with two-dimensional dilaton gravity is established.

description: For blood vessel regeneration, rapid endothelialization is essential by the effective modulation of vascular endothelial cells (VECs). Herein, microRNA-126 was loaded in electrospun membranes of poly(ethylene glycol)-b-poly(L-lactide-co-ε-caprolactone) combined with REDV peptide to promote VEC growth. The prepared electrospun membranes with suitable mechanical properties in the wet state could accelerate microRNA-126 release to 82.5 ± 4.0% in 56 days. VECs cultured on the electrospun membranes exhibited enhanced adhesion and proliferation with elongating and aligning morphology to the flow direction under shear stress compared with the static culture. The electrospun membranes containing REDV and microRNA-126 could have great potential in applications of bioactive vascular grafts.

description: The 2022 heatwave in India formed part of a pattern of extreme weather events in the country, which are becoming more intense, frequent, or prolonged. The aim of this study is to explore media coverage of climate change and extreme events in a multilingual media context such as India. Data analysis of a large and diverse sample of Indian media coverage of the 2022 heatwave (n = 309) suggests that only 1 in every 7 news articles (14%) mentioned climate change in their heatwave coverage in the English press, and less than 10% in the Hindi, Telugu, and Marathi language news media. However, many English-language articles reported the links between climate change and the heatwave, although the figure was much lower for the other languages. Two Event Attribution studies analyzing the heatwave were widely quoted, albeit with some inaccuracies. Indian scientists were the most cited, whereas politicians and NGOs were largely absent, in contrast to previous research. Journalists regularly covered three aspects that affect the impact of the heatwave on ordinary people, namely emergency responses, disaster planning, and vulnerabilities. This study concludes by exploring theoretical and practical recommendations for media coverage of heatwaves and climate change.
