description: Artificial intelligence (AI) and machine learning (ML) present revolutionary opportunities to enhance our understanding of animal behavior and conservation strategies. Using elephants, a crucial species in Africa's protected areas, as our focal point, we delve into the role of AI and ML in their conservation. Given the increasing amounts of data gathered from a variety of sensors like cameras, microphones, geophones, drones, and satellites, the challenge lies in managing and interpreting this vast data. New AI and ML techniques offer solutions to streamline this process, helping us extract vital information that might otherwise be overlooked. This paper focuses on the different AI-driven monitoring methods and their potential for improving elephant conservation. Collaborative efforts between AI experts and ecological researchers are essential in leveraging these innovative technologies for enhanced wildlife conservation, setting a precedent for numerous other species.

 Iridomyrmex krakatauae Wheeler, W.M., 1924: 252.
 Types. Holotype worker from Krakatau, Indonesia (not located during the study, apparently lost).
 Comments. Type material of this taxon could not be located during this study. Wheeler’s (1924) detailed description does not match any of the Iridomyrmex species known from the area where it was collected. Based on the original description, it seems unlikely that this taxon belongs to Iridomyrmex. Specifically, Wheeler (1924) notes the following: (1) The ant “lacks” a petiole (presumably he means petiolar node as a gaster is present). (2) The gaster is described as “somewhat deflective”, suggesting it is positioned ventrally. This is not a common position for Iridomyrmex but it is a common orientation in Tapinoma and Technomyrmex. (3) There is no mention of a medial clypeal prominence or anything corresponding to it. Instead, the anterior border of the clypeus is described as “almost straight”. In most of the northern Iridomyrmex that occur outside of Australia (for example I. anceps and I. coeruleus) this anatomical feature is distinct. (4) The ant is very small (1.5 mm). Of the Iridomyrmex occurring in this region, only I. mjobergi would be similar sized; however, I. mjobergi has a distinct petiolar node. (5) The propodeum is not protuberant, a condition found in Iridomyrmex species from this area. (6) The antennal scapes do not reach the posterior margin of the head, a very unusual condition for Iridomyrmex where they normally extend at least slightly beyond the posterior margin of head. (7) The propodeum is sloping and hardly raised, a condition found in Doleromyrma and Tapinoma but not Iridomyrmex. (8) The ant is completely glabrous while northern I. mjobergi always has a few hairs. (9) The posterior margins of the eyes only meet the imaginary horizontal line intersecting the middle of the head capsule. This is much further anterior than found in Iridomyrmex. Taken together, these characters suggest that this taxon belongs in Tapinoma or possibly Technomyrmex rather than Iridomyrmex. Based on the small size we are here transferring it to Tapinoma. Determining the species-level identification of this taxon will require the examination of Tapinoma material from throughout the Krakatau region, an undertaking beyond the scope of this study.

Subjects: subject: Classical Analysis and ODEs (math.CA)

description: We provide an explicit expression for the first order $q$-difference system for the Jackson integral of symmetric Selberg type. The $q$-difference system gives a generalization of $q$-analog of contiguous relations for the Gauss hypergeometric function. As a basis of the system we use a set of the symmetric polynomials introduced by Matsuo in his study of the $q$-KZ equation. Our main result is an explicit expression for the coefficient matrix of the $q$-difference system in terms of its Gauss matrix decomposition. We introduce a class of symmetric polynomials called interpolation polynomials, which includes Matsuo's polynomials. By repeated use of three-term relations among the interpolation polynomials we compute the coefficient matrix.

Adapting a gas accretion scenario for migrating planets in FARGO3D

Year: 2019
Subjects: subject: Earth and Planetary Astrophysics (astro-ph.EP)

description: FARGO3D has been proposed to investigate numerically the gravitational interaction of a planet with the gas disc, providing original outcomes. However, FARGO3D does not consider the gas accretion of the planet which may affect the planetary migration process. Thus, the aim of this paper is to include a model for the gas accretion in the FARGO3D code. For this task, we choose Russell's scheme, which is an adaptation of Kley's model for the gas accretion on to migrating planets. Initially, we study the influence of the gas accretion on to the planet on type II migration of giant planets. For this purpose, we follow the evolution of planets in a 2D locally isothermal disc with a specific accretion rate and different values of viscosity and planetary mass considering two scenarios. In the first, the gas mass is withdrawn from the disc and is not added to the planet. In the second, the planets migrate, while their masses grow due to the gas accretion. Then, we extend our study to estimate the time needed for a low-mass planet to open a gap in the gas disc and compare its value with the characteristic time of type I migration.

description: We report measurements of the transport and the magnetic properties of high-quality, sub-millimeter-sized MgB2 single crystals with clear hexagonal-plate shapes. The low-field magnetization and the magnetic hysteresis curves show the vortex pinning of these crystals to be very weak. The Debye temperature of $Θ_{D}\sim 1100$ K, obtained from the zero-field resistance curve, suggests that the normal-state transport properties are dominated by electron-phonon interactions. The resistivity ratio between 40 K and 300 K was about 5, and the upper critical field anisotropy ratio was 3 $\pm$ 0.2 at temperatures around 32 K.

description: We present a quantum eigenstate filtering algorithm based on quantum signal processing (QSP) and minimax polynomials. The algorithm allows us to efficiently prepare a target eigenstate of a given Hamiltonian, if we have access to an initial state with non-trivial overlap with the target eigenstate and have a reasonable lower bound for the spectral gap. We apply this algorithm to the quantum linear system problem (QLSP), and present two algorithms based on quantum adiabatic computing (AQC) and quantum Zeno effect respectively. Both algorithms prepare the final solution as a pure state, and achieves the near optimal $\mathcal{\widetilde{O}}(dκ\log(1/ε))$ query complexity for a $d$-sparse matrix, where $κ$ is the condition number, and $ε$ is the desired precision. Neither algorithm uses phase estimation or amplitude amplification.

description: Label-noise learning (LNL) aims to increase the model's generalization given training data with noisy labels. To facilitate practical LNL algorithms, researchers have proposed different label noise types, ranging from class-conditional to instance-dependent noises. In this paper, we introduce a novel label noise type called BadLabel, which can significantly degrade the performance of existing LNL algorithms by a large margin. BadLabel is crafted based on the label-flipping attack against standard classification, where specific samples are selected and their labels are flipped to other labels so that the loss values of clean and noisy labels become indistinguishable. To address the challenge posed by BadLabel, we further propose a robust LNL method that perturbs the labels in an adversarial manner at each epoch to make the loss values of clean and noisy labels again distinguishable. Once we select a small set of (mostly) clean labeled data, we can apply the techniques of semi-supervised learning to train the model accurately. Empirically, our experimental results demonstrate that existing LNL algorithms are vulnerable to the newly introduced BadLabel noise type, while our proposed robust LNL method can effectively improve the generalization performance of the model under various types of label noise. The new dataset of noisy labels and the source codes of robust LNL algorithms are available at https://github.com/zjfheart/BadLabels.

description: Non-resonant ferromagnetic x-ray diffraction has been used to separate the spin and orbital contribution to the magnetization density of the proposed zero-moment ferromagnet $Sm_{0.982}Gd_{0.018} Al_{2}$. The alignment of the spin and orbital moments relative to the net magnetization shows a sign reversal at 84K, the compensation temperature. Below this temperature the orbital moment is larger than the spin moment, and vice versa above it. This result implies that the compensation mechanism is driven by the different temperature dependencies of the $4f$ spin and orbital moments. Specific heat data indicate that the system remains ferromagnetically ordered throughout.

Nuclear Ashes: Reviewing Thirty Years of Nucleosynthesis in Classical Novae

Year: 2002
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: One of the observational evidences in support of the "thermonuclear runaway model" for the classical nova outburst relies on the accompanying nucleosynthesis. In this paper, we stress the relevant role played by nucleosynthesis in our understanding of the nova phenomenon by constraining models through a comparison with both the atomic abundance determinations from the ejecta and the isotopic ratios measured in presolar grains of a likely nova origin. Furthermore, the endpoint of nova nucleosynthesis provides hints for the understanding of the mixing process responsible for the enhanced metallicities found in the ejecta, and reveals also information on the properties of the underlying white dwarf (mass, luminosity...). We discuss first the interplay between nova outbursts and the Galactic chemical abundances: Classical nova outbursts are expected to be the major source of 13C, 15N and 17O in the Galaxy, and to contribute to the abundances of other species with A < 40, such as 7Li or 26Al. We describe the main nuclear path during the course of the explosion, with special emphasis on the synthesis of radioactive species, of particular interest for the gamma-ray output predicted from novae (7Li, 18F, 22Na, 26Al). An overview of the recent discovery of presolar nova candidate grains, as well as a discussion of the role played by nuclear uncertainties associated with key reactions of the NeNa-MgAl and Si-Ca regions, are also given.

description: Heat conduction in three types of 1D channels are studied. The channels consist of two parallel walls, right triangles as scattering obstacles, and noninteracting particles. The triangles are placed along the walls in three different ways: (a) periodic, (b) disordered in height, and (c) disordered in position. The Lyapunov exponents in all three models are zero because of the flatness of triangle sides. It is found numerically that the temperature gradient can be formed in all three channels, but the Fourier heat law is observed only in two disordered ones. The results show that there might be no direct connection between chaos (in the sense of positive Lyapunov exponent) and the normal thermal conduction.

Charge Fluctuations in Finite Coulomb Systems

Publisher: name: arXiv
Year: 2002
Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)
subject: FOS: Physical sciences

description: When described in a grand canonical ensemble, a finite Coulomb system exhibits charge fluctuations. These fluctuations are studied in the case of a classical (i.e. non-quantum) system with no macroscopic average charge. Assuming the validity of macroscopic electrostatics gives, on a three-dimensional finite large conductor of volume $V$, a mean square charge $$ which goes as $V^{1/3}$. More generally, in a short-circuited capacitor of capacitance $C$, made of two conductors, the mean square charge on one conductor is $=TC$, where $T$ is the temperature and $C$ the capacitance of the capacitor. The case of only one conductor in the grand canonical ensemble is obtained by removing the other conductor to infinity. The general formula is checked in the weak-coupling (Debye-Hückel) limit for a spherical capacitor. For two-dimensional Coulomb systems (with logarithmic interactions), there are exactly solvable models which reveal that, in some cases, macroscopic electrostatics is not applicable even for large conductors. This is when the charge fluctuations involve only a small number of particles. The mean square charge on one two-dimensional system alone, in the grand canonical ensemble, is expected to be, at most, one squared elementary charge.

description: Quantum devices offer a highly useful function - that is generating random numbers in a non-deterministic way since the measurement of a quantum state is not deterministic. This means that quantum devices can be constructed that generate qubits in a uniform superposition and then measure the state of those qubits. If the preparation of the qubits in a uniform superposition is unbiased, then quantum computers can be used to create high entropy, secure random numbers. Quantum annealing (QA) is a type of analog quantum computation that is a relaxed form of adiabatic quantum computation and uses quantum fluctuations in order to search for ground state solutions of a programmable Ising model. Here we present extensive experimental random number results from a D-Wave 2000Q quantum annealer, totaling over 20 billion bits of QA measurements, which is significantly larger than previous D-Wave QA random number generator studies. Current quantum annealers are susceptible to noise from environmental sources and calibration errors, and are not in general unbiased samplers. Therefore, it is of interest to quantify whether noisy quantum annealers can effectively function as an unbiased QRNG. The amount of data that was collected from the quantum annealer allows a comprehensive analysis of the random bits to be performed using the NIST SP 800-22 Rev 1a testsuite, as well as min-entropy estimates from NIST SP 800-90B. The randomness tests show that the generated random bits from the D-Wave 2000Q are biased, and not unpredictable random bit sequences. With no server-side sampling post-processing, the $1$ microsecond annealing time measurements had a min-entropy of $0.824$.

description: The relativistic quasiparticle random phase approximation (RQRPA) is formulated in the canonical single-nucleon basis of the relativistic Hartree-Bogoliubov (RHB) model. For the interaction in the particle-hole channel effective Lagrangians with nonlinear meson self-interactions are used, and pairing correlations are described by the pairing part of the finite range Gogny interaction. The RQRPA configuration space includes the Dirac sea of negative energy states. Both in the particle-hole and particle-particle channels, the same interactions are used in the RHB calculation of the ground state and in the matrix equations of the RQRPA. The RHB+RQRPA approach is tested in the example of multipole excitations of neutron rich oxygen isotopes. The RQRPA is applied in the analysis of the evolution of the low-lying isovector dipole strength in Sn isotopes and N=82 isotones.

description: Studies on the new MgB2 superconductor, with a critical temperature Tc ~ 39 K, have evidenced its potential for applications although intense magnetic relaxation effects limit the critical current density, Jc, at high magnetic fields. This means that effective pinning centers must be added into the material microstructure, in order to halt dissipative flux movements. Concerning the basic microscopic mechanism to explain the superconductivity in MgB2, several experimental and theoretical works have pointed to the relevance of a phonon-mediated interaction, in the framework of the BCS theory. Questions have been raised about the relevant phonon modes, and the gap and Fermi surface anisotropies, in an effort to interpret spectroscopic and thermal data that give values between 2.4 and 4.5 for the gap energy ratio. Preliminary results on the anisotropy of Hc2 have shown a ratio, between the in-plane and perpendicular directions, around 1.7 for aligned MgB2 crystallites and 1.8 for epitaxial thin films. Here we show a study on the angular dependence of Hc2 pointing to a Fermi velocity anisotropy around 2.5. This anisotropy certainly implies the use of texturization techniques to optimize Jc in MgB2 wires and other polycrystalline components.

description: Abstract: Homogeneous magnetic fields are required in different applications. The resolution of MRI techniques depends on the quality of the magnetic field, as well as the efficiency of electron cooling systems used at particle accelerators. Unclosed magnetic shield made of superconducting tapes is able to nullify the radial component of a solenoidal magnetic field, forming the long region of the homogeneous magnetic field. The shield is a lengthwise winding made from YBCO tapes are wound along a carcass generatrix. Then it is positioned coaxially inside an electromagnet. The measurements were carried out under quasistationary conditions, magnetic fields up to 1 kG at 77K. This paper discusses the design of the superconducting shield and presents experimental and numerical studies into the homogeneity of the magnetic field in solenoids with the superconducting shield.

description: This study examines the impact of multiple shocks on assets by employing two waves of a panel data set of 360 rural households in three agro-ecological zones in Kenya. To control for unobserved heterogeneity, a ‘within’ household fixed effects model was employed. One major finding is that climatic shocks negatively affect households’ livestock holdings -apart from small ruminant and non-ruminant livestock due to their higher adaptive capacity. Consequently, households rely on two major coping strategies to smooth their consumption level: (1) adjusting their livestock portfolios, and (2) borrowing from group-based approaches. The latter strategy is particularly important for poor households in safeguarding their already low asset base. The findings suggest that livestock protection policies, such as diversification of livestock portfolios, promotion of fodder banks and index-based livestock insurance, are substantial. Scaling-up of group-based approaches would augment poor households’ recovery and resilience against multiple shocks in the face of accelerating climate change.

 Iridomyrmex florissantius Carpenter, 1930: 50.
 Types. Holotype queen from the United States (Oligocene).
 Comments. This species, based on a series of impression fossil queens, is only tentatively placed in Iridomyrmex as very little morphological detail is available. It is unlikely that this species is related to modern Iridomyrmex, but so little information is available that it is extremely difficult to determine its true relationships. As such it is retained in Iridomyrmex as incertae sedis with strong reservations that it actually belongs here.

description: Abstract: Active control of chirality in the terahertz frequency range is of great importance in many scientific areas, which include research into fundamental optical phenomena, investigation of novel materials, spectroscopy, imaging, wireless communications and chemistry. The lack of efficient, integrated and fast-reconfigurable polarization modulators has hindered, so far, the full exploitation of applications in all the aforementioned fields. Metamaterials are artificial resonant elements possessing unique remarkable properties such as high efficiency and miniaturization capability. The interplay of metallic metamaterial arrays with electrostatically tunable monolayer graphene has been demonstrated to be a valid approach for the realization of a novel class of THz devices. In this work, the realization of active chiral graphene/metamaterial modulator is presented. The versatility of this experimental approach allowed the device integration with broadband sources such as terahertz time domain spectrometers as well as with quantum cascade lasers. A continuous rotation of the polarization plane > 30° has been reported with a reconfiguration speed > 5 MHz. These results pave the way to the integration of fast terahertz polarization modulators in all the applications where these devices are in great demand.

description: We show that the most general two-dimensional dilaton gravity theory with second-order field equations, which includes Horndeski and Kinetic Gravity Braiding families, may be obtained from the Jackiw-Teitelboim (JT) gravity through a general disformal transformation, up to boundary terms. This map does not change the degrees of freedom if the invertible transformation is applied. We also show that this most general family of theories is closed under generic disformal transformations.

description: Methods for nanoscale material characterization are in ever-increasing demand, especially those that can provide a broader range of information at once. Near-field techniques based on combinations of scanning probe microscopy (SPM) and Raman or photoluminescence (PL) spectroscopy (tip-enhanced Raman spectroscopy [TERS] and/or tip-enhanced photoluminescence [TEPL]) are, thanks to their capabilities and fast development, strong candidates for becoming widespread across the scientific community as SPM and Raman microscopy did only a decade or two ago. Herein, a gap-less TEPL study is performed directly on as-grown MoS2 monolayer samples without any pretreatment or transfer, i.e., without the utilization of plasmonic substrate. Thanks to a mapping resolution as low as a few tens of nanometers, homogeneous layer interiors from defective edge fronts in the grown monolayers can be distinguished. With the aid of additional high-resolution SPM modes, like local surface potential and capacitance measurements, together with nanomechanical mapping, a combination of defects and a lack of substrate doping is suggested as being responsible for the observed PL behavior in the partially delaminated MoS2 layers. In contrast, mechanically exfoliated flakes show topography- and contamination-related heterogeneities in the whole flake area.

description: The article describes the findings of a study on the credit programmes designed for the small farmers and landless poor, by some government and non-government organizations. It was found that the programmes under consideration provided employment opportunity to the participants at least for the project period. Housewives also benefited from the programmes since they could utilize their leisure time productively by engaging themselves in income generating activities. However, it was found that many of the loanee-participants could not yet settle permanently with any particular occupation in spite of a number of years of involvement in the project. A good number of loanees still depend on selling labour. The amount of credit provided by most of the organizations was reported to be highly inadequate. Many participants also borrowed from other institutional and non-institutional sources. The main trust of these programmes was found to be augmenting monetary benefits rather than overall development of the participating families.

description: Recently, Huang and Lin suggested a combination of two successfull mean-field theories, the 2-cluster approximation and paradisical mean-field, for the Nagel-Schreckenberg cellular automaton model of traffic flow. We argue that this new approximation is inconsistent since it violates the Kolmogorov conditions.

description: Abstract: In this contribution in honour of Paul Busch, we criticise the claims of many expositions that the time-energy uncertainty principle allows both a violation of energy conservation and particle creation, provided that this happens for a sufficiently short time. But we agree that there are grains of truth in these claims: which we make precise and justify using perturbation theory.

description: Farm surveys in 1985 in Joydebpur, Nawabganj, Chandina, Daudkandi, Dhamrai and Manikgonj showed that yield gaps were about 1.3 t/ha in Boro, 1.0 t/ha in Aus and 0.7 t/ha in T. Aman. About 63-76% of the yield gap resulted from the low use of fertilizers. Among farmers who believed higher use of fertilizers could increase their yields, the majority of them could not adequately fertilize for want of hand cash or for the high price of fertilizers. The estimated per hectare cash cost of production for growing modern moieties of rice during 1985 was Tk. 10,965 for Boro, Tk. 5,416 for Aus and Tk. 4,525 for T. Aman. The maximum amount of credit so far received by the survey farmers did not, however, exceed Tk. 2,560/family. A significant portion of credit was spent to meet consumption seeds. A larger proportion of small T. Aman producers re- paid their loan compared to medium and large producers.

description: We report the preparation and observation of single atoms of dysprosium in arrays of optical tweezers with a wavelength of 532 nm imaged on the intercombination line at 626 nm. We use the anisotropic light shift specific to lanthanides and in particular a large difference in tensor and vector polarizabilities between the ground and excited states to tune the differential light shift and produce tweezers in near-magic or magic polarization. This allows us to find a regime where single atoms can be produced and imaged. Using the tweezer array toolbox to manipulate lanthanides will open new research directions for quantum physics studies by taking advantage of their rich spectrum, large spin and magnetic dipole moment.
Optical conductivity of one-dimensional narrow-gap semiconductors

description: The optical conductivities of two one-dimensional narrow-gap semiconductors, anticrossing quantum Hall edge states and carbon nanotubes, are studied using bosonization method. A lowest order renormalization group analysis indicates that the bare band gap can be treated perturbatively at high frequency/temperature. At very low energy scale the optical conductivity is dominated by the excitonic contribution, while at temperature higher than a crossover temperature the excitonic features are eliminated by thermal fluctuations. In case of carbon nanotubes the crossover temperature scale is estimated to be 300 K.

description: We present a detailed analysis of two well-localized, highly offset short gamma-ray bursts---GRB~070809 and GRB~090515---investigating the kinematic evolution of their progenitors from compact object formation until merger. Calibrating to observations of their most probable host galaxies, we construct semi-analytic galactic models that account for star formation history and galaxy growth over time. We pair detailed kinematic evolution with compact binary population modeling to infer viable post-supernova velocities and inspiral times. By populating binary tracers according to the star formation history of the host and kinematically evolving their post-supernova trajectories through the time-dependent galactic potential, we find that systems matching the observed offsets of the bursts require post-supernova systemic velocities of hundreds of kilometers per second. Marginalizing over uncertainties in the stellar mass--halo mass relation, we find that the second-born neutron star in the GRB~070809 and GRB~090515 progenitor systems received a natal kick of $\gtrsim 200~\mathrm{km\,s}^{-1}$ at the 78\% and 91\% credible levels, respectively. Applying our analysis to the full catalog of localized short gamma-ray bursts will provide unique constraints on their progenitors and help unravel the selection effects inherent to observing transients that are highly offset with respect to their hosts.

description: Iridomyrmex mapesi Wilson, incertae sedis
 Iridomyrmex mapesi Wilson, 1985a: 211.
 Types. Holotype worker from the United States (Eocene).
 Comments. The condition of the only known specimen of this species is so poor that discussions of its morphology are limited to the most general and vague characterisation. Wilson (1985a) notes that the species possesses fewer mandibular teeth than New World species then placed in Iridomyrmex (now placed in Linepethima). He compares the mandibles with those of extant Australian species, finding them similar to I. calvus and I. rufoniger, as well as what is now Philidris cordatus. Essentially no other details are provided. With so little information available it is impossible to support a specific generic placement of this taxon, and it is retained here as incertae sedis, acknowledging that this placement in Iridomyrmex is unsupported and likely to be incorrect based on biogeographic considerations and the great age difference between this species and the origins of modern members of Iridomyrmex.
