description: Classical chaotic dynamics is characterized by the exponential sensitivity to initial conditions. Quantum mechanics, however, does not show this feature. We consider instead the sensitivity of quantum evolution to perturbations in the Hamiltonian. This is observed as an atenuation of the Loschmidt Echo, $M(t)$, i.e. the amount of the original state (wave packet of width $σ$) which is recovered after a time reversed evolution, in presence of a classically weak perturbation. By considering a Lorentz gas of size $L$, which for large $L$ is a model for an {\it unbounded} classically chaotic system, we find numerical evidence that, if the perturbation is within a certain range, $M(t)$ decays exponentially with a rate $1/τ_ϕ$ determined by the Lyapunov exponent $λ$ of the corresponding classical dynamics. This exponential decay extends much beyond the Eherenfest time $t_{E}$ and saturates at a time $t_{s}\simeq λ^{-1}\ln (\widetilde{N})$, where $\widetilde{N}\simeq (L/σ)^2$ is the effective dimensionality of the Hilbert space. Since $τ_ϕ$ quantifies the increasing uncontrollability of the quantum phase (decoherence) its characterization and control has fundamental interest.

The Effect of General Relativistic Precession on Tidal Disruption Events from Eccentric Nuclear Disks

Subjects: subject: High Energy Astrophysical Phenomena (astro-ph.HE)

description: An eccentric nuclear disk consists of stars moving on apsidally-aligned orbits around a central black hole. The secular gravitational torques that dynamically stabilize these disks can also produce tidal disruption events (TDEs) at very high rates in Newtonian gravity. General relativity, however, is known to quench secular torques via rapid apsidal precession. Here we show that for a disk to black hole mass ratio $\gtrsim 10^{-3}$, the system is in the full loss cone regime. The magnitude of the torque per orbital period acting on a stellar orbit means that general relativistic precession does not have a major effect on the dynamics. Thus we find that TDE rates from eccentric nuclear disks are not affected by general relativistic precession. Furthermore, we show that orbital elements between successive TDEs from eccentric nuclear disks are correlated, potentially resulting in unique observational signatures.

description: Excerpts from the report Preface: Transportation and refrigeration costs account for a substantial part of the total costs of marketing peaches and other fresh fruits and vegetables. Loading methods which increase the rate of utilization of space in the vehicle provide a practical means by which the cost of these services per package can be reduced. The loading methods, however, must be consistent with proper air circulation, adequate refrigeration and ventilation, and structural and legal weight limitations of the vehicle. This study was made to determine the feasibility of adapting the alternately inverted loading method for baskets of peaches to motortruck shipments of the fruit, so as to reduce transportation costs. The study is part of a continuing program of research to reduce costs and improve the efficiency of transportation and marketing of agricultural products.

description: Lung cancer is the main responsible of cancer deaths, nowadays constituting the forth most frequent death in Spain. Being the percentage of individuals who smoke and develop lung cancer only of 20%, there may be additional genetic polymorphisms in critical genes and environmental factors altering the susceptibility to acquire lung cancer, affecting both of them differently to men and women. Over the last few years, significant studies associated with gene expression for lung adenocarcinoma have been performed in order to characterize relevant mutations. In this study, a selection of omics datasets is carried out so that only men and women with stage I-II lung adenocarcinoma are considered together with control cases, strengthening the utility of these data for the further analysis. This approach allowed the characterization and deeper understanding of the expression genes that are significant for men and women when developing lung adenocarcinoma, as well as their comparison with the expression genes usually present in both genders, obtaining the biological changes occurring in them when the disease is present. An integrative meta-analysis of the samples has been performed and with the results, common and different significant genes for both genders have been found. A functional classification of them has been also done so that the biological function of the genes is obtained as well as a statistical over-representation test that states the difference in function of mutated and normal significant genes. The identification of different linked genes for them confirm a different origin and progression of the disease. Therefore, the established conclusions could be used in future studies in order to separate genders in two different lines of research with different therapeutic targets that would lead to more suitable specific treatments with a better response.
4$π$ and 8$π$ dual Josephson effects induced by symmetry defects

description: In topological insulator edges, the duality between the Zeeman field orientation and the proximitized superconducting phase has been recently exploited to predict a magneto-Josephson effect with a 4$π$ periodicity. We revisit this latter Josephson effect in the light of this duality and show that the same 4$π$ quantum anomaly occurs when bridging two spinless Thouless pumps to a p-wave superconducting region that could be as small as a single and experimentally-relevant superconducting quantum dot - a point-like defect. This interpretation as a dual Josephson effect never requires the presence of Majorana modes but rather builds on the topological properties of adiabatic quantum pumps with Z topological invariants. It allows for the systematic construction of dual Josephson effects of arbitrary periodicity, such as 4$π$ and 8$π$, by using point-like defects whose symmetry differs from that of the pump, dubbed symmetry defects. Although adiabatic quantum pumps are typically discussed via mappings to two-dimensional geometries, we show that this phenomenology does not have any counterpart in conventional two-dimensional systems.

description: We investigate the electronic structure of realistic partial dislocation networks in bilayer graphene that feature annihilating, wandering, and intersecting partial lines. We find charge accumulation states at partials that are sensitive to Fermi energy and partial Burgers vector but not to the screw versus edge character of the partial. These states are shown to be current carrying, with the current density executing a spiral motion along the dislocation line with a strong interlayer component to the current. Close to the Dirac point localization on partials switches to localization on intersections of partials, with a corresponding complex current flow around the nodes.

description: The dynamics of a two-component dilute Bose gas of atoms at zero temperature is described in the mean field approximation by a two-component Gross-Pitaevskii Equation. We solve this equation assuming a Gaussian shape for the wavefunction, where the free parameters of the trial wavefunction are determined using a moment method. We derive equilibrium states and the phase diagrams for the stability for positive and negative s-wave scattering lengths, and obtain the low energy excitation frequencies corresponding to the collective motion of the two Bose condensates.

description: The binding energies of argon dimer are calculated by solving the homogeneous Lippmann-Schwinger integral equation in momentum space. Our numerical analysis using two models of argon-argon interaction developed by Patkowski {\it et al.} confirms not only the eight argon dimer vibrational levels of the ground state of argon dimer (i.e. for $j=0$) predicted by other groups but also provides a very precise means for determining the binding energy of the ninth state which its value is a matter of discussion. Our calculations have been also extended to states with higher rotational quantum number $j$ and we have calculated the energy of all 174 bound states for both potential models. Our numerical results for vibrational levels of the ground state of argon dimer are in excellent agreement with other theoretical calculations and available experimental data.
Consolidating the Optimal Design of Distributed Energy Systems and Optimal Power Flow
Creators: name: De Mel, Ishanki
Publisher: name: Zenodo
Year: 2021

description: As the power industry moves towards decentralised generation and distribution to increase energy access and reliability, the implementation of Distributed Energy Systems (DES) and microgrids are on the rise. These utilise small-scale community-owned generation and storage technologies (including renewable energy resources), and are usually connected to external networks, such as the alternating current (AC) electrical grid. Optimisation models are frequently used to determine the designs and operational schedules of DES, under objectives such as minimised cost and/or carbon emissions. They are generally formulated as mixed-integer linear programming (MILP) problems, which exclude vital nonlinear and nonconvex constraints representing AC power flow and the underlying distribution network. Optimal AC power flow is generally treated as a standalone problem, which does not influence DES decisions, as these representations can significantly increase model complexity. Furthermore, the impact of combining nonlinear AC power flow with DES models has been insufficiently investigated. This study aims to address this gap and consolidate two previously standalone problems. A MILP model is used to represent the base DES formulation. The inclusion of nonlinear power flow constraints within DES design models, considering active and reactive power balances, current calculations, and network topology, is demonstrated using a mixed-integer nonlinear programming (MINLP) formulation. A low-voltage residential network is used to test both formulations. Significant differences are seen in the resulting designs of the two models, particularly when electricity storage in unavailable. The results also emphasise the importance of including nonlinear power flow constraints within the DES framework, as this can produce practically feasible results when compared with the base DES formulation. Thus, the study contributes to more detailed modelling, to enable the wider implementation of DES.

description: We investigate the global spacetime structure of torus de Sitter universe, which is exact de Sitter space with torus identification based on the flat chart. We show that past incomplete null geodesics in torus de Sitter universe are locally extendible. Then we give an extension of torus de Sitter universe so that at least one of the past incomplete null geodesics in the original spacetime becomes complete. However we find that extended torus de Sitter universe has two ill behaviors. The first one is a closed causal curve. The second one is so called quasi regular singularity, which means that there is no global, consistent extension of spacetime where all curves become complete, nevertheless each curve is locally extensible.

description: We describe an algebraic way to code the causal information of a discrete spacetime. The causal set C is transformed to a description in terms of the causal pasts of the events in C. This is done by an evolving set, a functor which to each event of C assigns its causal past. Evolving sets obey a Heyting algebra which is characterised by a non-standard notion of complement. Conclusions about the causal structure of the causal set can be drawn by calculating the complement of the evolving set. A causal quantum theory can be based on the quantum version of evolving sets, which we briefly discuss.

description: The equivalence between the Chern-Simons gauge theory on a three-dimensional manifold with boundary and the WZNW model on the boundary is established in a simple and general way using the BRST symmetry. Our approach is based on restoring gauge invariance of the Chern-Simons theory in the presence of a boundary. This gives a correspondence to the WZNW model that does not require solving any constraints, fixing the gauge or specifying boundary conditions.

description: Residence times of a particle in both the wells of a double-well system, under the action of zero-mean Gaussian white noise and zero-averaged but temporally asymmetric periodic forcings, are recorded in a numerical simulation. The difference between the relative mean residence times in the two wells shows monotonic variation as a function of asymmetry in the periodic forcing and for a given asymmetry the difference becomes largest at an optimum value of the noise strength. Moreover, the passages from one well to the other become less synchronous at small noise strength as the asymmetry parameter (defined below) differs from zero, but at relatively larger noise strengths the passages become more synchronous with asymmetry in the field sweep. We propose that asymmetric periodic forcing (with zero mean) could provide a simple but sensible physical model for unidirectional motion in a symmetric periodic system aided by a symmetric Gaussian white noise.

description: We present new general relationships among the material properties of an isotropic material kept in homogeneous stress conditions with hydrostatic pressure and plane shear. The derivation is not limited to the proximity of the zero shear-stress and -strain condition, which allows us to identify the relationship between adiabatic and isothermal shear compliances (inverse of the moduli of rigidity) along with new links, among others, between isobaric and isochoric shear thermal expansion coefficients, heat capacities at constant stress and constant shear strain. Such relationships are important for a variety of applications, including characterization of nanomaterials as well as identification of properties related to earthquakes precursors and complex media (e.g., soil) behaviors. The results may be useful to investigate the behavior of materials during phase transitions involving shear or in non-homogeneous conditions within a local thermodynamic equilibrium framework.

The gravitational action is rendered finite using a local counterterm prescription, and the relation of this method to the traditional reference spacetime is discussed. For AdS, an iterative procedure is devised that determines the counterterms efficiently. For asymptotically flat space, we use a different method to derive counterterms which are sufficient to remove divergences in most cases.

description: We have identified ultra-cold atoms in magneto-optical double-well potentials as a very clean setting in which to study the quantum and classical dynamics of a nonlinear system with multiple degrees of freedom. In this system, entanglement at the quantum level and chaos at the classical level arise from nonseparable couplings between the atomic spin and its center of mass motion. The main features of the chaotic dynamics are analyzed using action-angle variables and Poincare surfaces of section. We show that for the initial state prepared in current experiments [D. J. Haycock et al., Phys. Rev. Lett. 85, 3365 (2000)], the classical and quantum dynamics diverge, and the observed experimental dynamics are best described by quantum mechanics. Furthermore, the motion corresponds to tunneling through a dynamical potential barrier. The coupling between the spin and the motional subsystems, which are very different in nature from one another, leads to new questions regarding the transition from regular quantum dynamics to chaotic classical motion.

description: The “death roll” is an iconic crocodylian behaviour, and yet it is documented in only a small number of species, all of which exhibit a generalist feeding ecology and skull ecomorphology. This has led to the interpretation that only generalist crocodylians can death roll, a pattern which has been used to inform studies of functional morphology and behaviour in the fossil record, especially regarding slender-snouted crocodylians and other taxa sharing this semi-aquatic ambush predator body plan. In order to test this hypothesis, we surveyed death roll behaviour across animals representing all extant crocodylian species. Animals were prompted to death roll using two methods of stimulation: a feeding cue and an escape cue. The feeding cue involved presenting each animal with a bait item, to which resistance would be applied during a biting event. The second cue involved capturing each animal with a rope or catch pole, a standard technique for capturing crocodylians, but one that also often prompts an attempt to escape. All species tested, except Paleosuchus palpebrosus, exhibited the behaviour in response to at least one of the stimuli. This included the following slender-snouted species: Gavialis gangeticus, Tomistoma schlegelii, Mecistops cataphractus, Mecistops leptorhynchus, Crocodylus johnstoni, and Crocodylus intermedius. The patterns of death roll behavior observed in this survey suggest that this behaviour is not novel to any one crocodylian clade, morphotype, or dietary niche. Also, the prevalence of death rolling behaviour across Crocodylia in response to perceived threats indicates that it is not solely, or maybe even primarily, a feeding behaviour, but is also utilised during inter- and intra-specific conflict as a means to escape or injure an opponent. The results of this case study highlight the importance of using multiple modern analogues when attempting to correlate form and function across diverse clades, both living and extinct.

description: Fatty acids, known for their hydrocarbon chains spanning between 4 and 36 carbons, play a crucial role in various biological processes. Natural fats primarily consist of straight-chain fatty acids with an even number of carbon atoms. Fatty acid synthesis, or lipogenesis, predominantly occurs in the cytosol and is essential for several tissues, including the liver, kidneys, brain, and adipose tissue. The rate of lipogenesis is closely tied to an organism's nutritional status, increasing in well-fed animals with a high-carbohydrate diet and decreasing under caloric restriction or insulin deficiency, such as in diabetes mellitus.

Cholesterol, a key sterol, exists in animal tissues in the form of lipoproteins and free cells, or as esters in the bloodstream. Cholesterol esters serve as a common storage and transport form, while free cholesterol often transforms into bile acids. Unsaturated fatty acids within cell membrane phospholipids play a vital role in maintaining membrane fluidity.

High-Density and Low-Density Lipoproteins (HDL and LDL) are essential in transporting cholesterol to and from the liver. HDL, often referred to as "good cholesterol," aids in cholesterol exchange and its elimination in the bile. Clinical disorders related to fatty acid metabolism primarily involve oxidation processes, with triacylglycerides being the most prevalent lipid family, consisting of fatty acids and glycerol and serving as a major storage lipid

description: Nucleotides and other phosphate-containing compounds are integral to enzymatic reactions such as those of the methylerythritol phosphate (MEP) pathway and glycolysis. Traditional chromatographic analysis of phosphates is often plagued by long run times and/or lack of MS compatibility. This study compares separation of five enzymatically-important nucleotides using ion-pair reversed phase (IP-RP), strong anion exchange (SAX), and hydrophilic interaction (HILIC) methods. These three methods were evaluated and compared based on separation parameters describing retention, resolution, efficiency, peak symmetry, selectivity, and inter- and intraday peak drift. Use of the FructoShell-N HILIC column led to separation of the five nucleotides isocratically with the shortest run time of all three methods tested. Additionally, the FructoShell HILIC method yielded a very low intraday variability and low peak asymmetry, issues that are often observed with HILIC separations on other stationary phases. To our knowledge, this column has not been applied to the separation of phosphates in biological samples and future work will focus on in vitro and in vivo analysis as well as broadening the applicability to other pathways. To this end, we have shown that the column will retain fructose bisphosphate, the substrate of the aldolase enzyme, under the same chromatographic conditions used for nucleotides.

description: We find an analytic solution of the Bethe Ansatz equations (BAE) for the special case of a finite XXZ spin chain with free boundary conditions and with a complex surface field which provides for $U_q(sl(2))$ symmetry of the Hamiltonian. More precisely, we find one nontrivial solution, corresponding to the ground state of the system with anisotropy parameter $Δ= {1/2}$ corresponding to $q^3 = -1$. With a view to establishing an exact representation of the ground state of the finite size XXZ spin chain in terms of elementary functions, we concentrate on the crossing-parameter $η$ dependence around $η=π/3$ for which there is a known solution. The approach taken involves the use of a physical solution $Q$ of Baxter's t-Q equation, corresponding to the ground state, as well as a non-physical solution $P$ of the same equation. The calculation of $P$ and then of the ground state derivative is covered. Possible applications of this derivative to the theory of percolation have yet to be investigated. As far as the finite XXZ spin chain with periodic boundary conditions is concerned, we find a similar solution for an assymetric case which corresponds to the 6-vertex model with a special magnetic field. For this case we find the analytic value of the ``magnetic moment'' of the system in the corresponding state.

description: In contemporary mental health practices, the assessment of treatment outcomes has become imperative, driven by the need for accountability and effective allocation of healthcare resources. This demand for "returns on investment" is a shared responsibility, integral to the therapeutic alliance. Feedback-Informed Treatment (FIT) is an empirically supported methodology for assessing and enhancing the quality and efficacy of behavioral health services. Grounded in Solution-Focused Brief Therapy, FIT involves systematic feedback collection from clients to inform and tailor service delivery. Ongoing outcome evaluations not only inform clinical decision-making but also enhance treatment outcomes. Early client perception of improvement emerges as a significant predictor of treatment success. Incorporating client feedback into counseling supervision has additional advantages, such as improving counselor self-efficacy and ensuring ethical and competent treatment. Various professional organizations, including the British Association for Counseling and Psychotherapy (BACP) and American Counseling Association (ACA), mandate supervision for ethical reasons, serving as an impartial oversight mechanism to reduce the risk of therapeutic oversights and facilitate counselor self-reflection

In this paper, we present MAXENT3D_PID, a production-quality software that computes the trivariate partial information measure based on the Cone Programming model. We describe in detail our software, explain how to use it, and perform some experiments reflecting its accuracy in estimating the trivariate partial information decomposition.

description: In this paper, we propose a class of false analog data injection attack that can misguide the system as if topology errors had occurred. By utilizing the measurement redundancy with respect to the state variables, the adversary who knows the system configuration is shown to be capable of computing the corresponding measurement value with the intentionally misguided topology. The attack is designed such that the state as well as residue distribution after state estimation will converge to those in the system with a topology error. It is shown that the attack can be launched even if the attacker is constrained to some specific meters. The attack is detrimental to the system since manipulation of analog data will lead to a forged digital topology status, and the state after the error is identified and modified will be significantly biased with the intended wrong topology. The feasibility of the proposed attack is demonstrated with an IEEE 14-bus system.

In this article, however, we report cubic azimuthal modes in heterogeneous nanodisks consisting of a permalloy core and a Fe shell. The fourfold symmetry of azimuthal modes is due to the exchange, and magneto-static, interactions between the permalloy core and the Fe shell. In comparison to results of circular azimuthal mode, the vortex switching occurs considerably faster under the excitation of cubic azimuthal mode. The gyration path of vortex core turns into square under the influence of induced cubic anisotropy in the Py region. We find out periodic oscillation of the vortex core size and the gyration speed as well. Our findings may offer a new route for spintronic applications using heterogeneous magnetic nanostructures.

description: An introduction to the application of combinatorial optimization methods to ground state calculations of frustrated, disordered systems is given. We discuss the interface problem in the random bond Ising ferromagnet, the random field Ising model, the diluted antiferromagnet in an external field, the spin glass problem, the solid-on-solid model with a disordered substrate and other convex cost flow problems occurring in superconducting flux line lattices and traffic flow networks. On the algorithmic side we present a concise introduction to a number of elementary algorithms in combinatorial optimization, in particular network flows: the shortest path algorithm, the maximum-flow algorithms and minimum-cost-flow algorithms. We present a short glance at the minimum weighted matching and branch-and-cut algorithms.

description: We study 2+1 Chern-Simons gravity at the classical action level. In particular we rederive the linear combinations of the ``standard'' and ``exotic'' Einstein actions, from the (anti) self-duality of the ``internal'' Lorentzian indices. The relation to a genuine four-dimensional (anti)self-dual topological theory greatly facilitates the analysis and its relation to hyperbolic three-dimensional geometry. Finally a non-abelian vector field ``dual'' action is also obtained.

description: We study the time evolution of an initially excited many-body state in a finite system of interacting Fermi-particles in the situation when the interaction gives rise to the ``chaotic'' structure of compound states. This situation is generic for highly excited many-particle states in quantum systems, such as heavy nuclei, complex atoms, quantum dots, spin systems, and quantum computers. For a strong interaction the leading term for the return probability $W(t)$ has the form $W(t)\simeq \exp (-Δ_E^2t^2)$ with $Δ_E^2$ as the variance of the strength function. The conventional exponential linear dependence $W(t)=C\exp (-Γt)$ formally arises for a very large time. However, the prefactor $C$ turns out to be exponentially large, thus resulting in a strong difference from the conventional estimate for $W(t)$.

description: High-harmonic generation (HHG) from a compact, solid-state medium is highly desirable for applications such as coherent attosecond pulse generation and extreme ultra-violet (EUV) spectroscopy, yet the typically weak conversion of pump light to HHG can largely hinder its applications. Here, we use a material operating in its epsilon-near-zero (ENZ) region, where the real part of its permittivity vanishes, to greatly boost the efficiency of the HHG process at the microscopic level. In experiments, we report high-harmonic emission up to the 9th order directly from a low-loss, solid-state ENZ medium: indium-doped cadmium oxide, with an excitation intensity at the GW cm-2 level. Furthermore, the observed HHG signal exhibits a pronounced spectral red-shift as well as linewidth broadening, resulting from the photo-induced electron heating and the consequent time-dependent resonant frequency of the ENZ film. Our results provide a novel nanophotonic platform for strong field physics, reveal new degrees of freedom for spectral and temporal control of HHG, and open up possibilities of compact solid-state attosecond light sources.

Subjects: Depression, Quality of Life, Epilepsy Patients

description: Abstract

Introduction: Epilepsy may have significant negative effects on a person's quality of life in terms of their physical, social, and psychological well-being. Primary epilepsy and depression are well-known co-morbid mental conditions. Objective: Comparing depression and QOL among epilepsy patients visiting the epilepsy outpatient clinic was the aim of the current study. Methods: A Cross-sectional study with a total of sixty cases of primary epilepsy patients were recruited in the study, after informed consent. They were interviewed on the self-administered NIDDE and QOLIE-31 questionnaire while they were waiting in the epilepsy outpatient clinic. Patients with a score of over 14 were classified as depressed. Higher scores also denote better quality of life. SPSS version was used to analyze the results. Results: Sixty individuals were evaluated, and 32 (53.33%) had high likely depression and a middling quality of life was experienced by 40 people (66.66%). A negative connection between depression and quality of life is evident based on the estimated Karl Pearson's connection 'r' value of r = -0.365, which is statistically significant at the p<0.01 level. Conclusion: Patients with epilepsy reported moderate quality of life, and depression levels were high. Consequently, worse HRQOL was linked to depression ratings. Therefore, healthcare professionals should place more attention on patients who they consider to be stigmatized, who have a higher frequency of seizures, and who have a low degree of social support.
