description: L'étude visait à identifier les caractéristiques sociales et économiques des élèves mendiants du Saint Coran qui étudient dans des écoles coraniques mobiles, et les raisons de la mendicité qui appartiennent à l'enfant lui-même, à sa famille et à la société dans son ensemble, y compris l'État. Pour cela, le chercheur a mené une étude de terrain de la plupart des écoles coraniques des villes d'Abéché et d’Oumhadjar, en plus d'interroger de nombreux responsables des écoles coraniques et associations travaillant dans la même formulation, où un questionnaire a été soumis par l'inventaire complet méthode. Afin d'atteindre les objectifs de l'étude, on s'est appuyé sur les approches appropriées pour recueillir ses données. Le chercheur a également utilisé le programme d'analyse statistique en sciences sociales (SPSS) pour analyser les données du questionnaire.  Afin d'utiliser des méthodes statistiques appropriées et d'appliquer l'énoncé des différences et des relations statistiquement significatives entre les moyennes des changements dépendants et indépendants, en utilisant la méthode de la variance unidirectionnelle, le T - test et le programme Word pour concevoir des cercles et des cubes qui aident à interpréter certains des tableaux de l'étude.

description: Various coefficients of the 3.5 post-Newtonian (PN) phasing formula of non-spinning compact binaries moving in circular orbits is fully characterized by the two component masses. If two of these coefficients are independently measured, the masses can be estimated. Future gravitational wave observations could measure many of the 8 independent PN coefficients calculated to date. These additional measurements can be used to test the PN predictions of the underlying theory of gravity. Since all of these parameters are functions of the two component masses, there is strong correlation between the parameters when treated independently. Using Singular Value Decomposition of the Fisher information matrix, we remove this correlations and obtain a new set of parameters which are linear combinations of the original phasing coefficients. We show that the new set of parameters can be estimated with significantly improved accuracies which has implications for the ongoing efforts to implement parametrised tests of PN theory in the data analysis pipelines.

description: We investigate kink-antikink scattering in the $λϕ^4$ model in the presence of an additional scalar field, $ψ$, that is in its quantum vacuum and interacts with $ϕ$ via a $ξϕ^2ψ^2$ term where $ξ$ is the coupling. The final state of such a scattering is either a bound state with eventual annihilation or a reflection of the kink-antikink pair. Without the $ψ$ field, the outcome is known to depend fractally on the initial velocity of the kink-antikink pair. In the quantum vacuum of the $ψ$ field, the fractal dependence gets modified and disappears above a critical interaction strength, $ξ\approx 0.1$.

description: In this work we theoretically analyze a circuit QED design where propagating quantum microwaves interact with a single artificial atom, a single Cooper pair box. In particular, we derive a master equation in the so-called transmon regime, including coherent drives. Inspired by recent experiments, we then apply the master equation to describe the dynamics in both a two-level and a three-level approximation of the atom. In the two-level case, we also discuss how to measure photon antibunching in the reflected field and how it is affected by finite temperature and finite detection bandwidth.

description: Coherent transduction of quantum states from the microwave to the optical domain can play a key role in quantum networking and distributed quantum computing. We present the design of a piezo-optomechanical device formed in a hybrid lithium niobate on silicon platform, that is suitable for microwave-to-optical quantum transduction. Our design is based on acoustic hybridization of an ultra-low mode volume piezoacoustic cavity with an optomechanical crystal cavity. The strong piezoelectric nature of lithium niobate allows us to mediate transduction via an acoustic mode which only minimally interacts with the lithium niobate, and is predominantly silicon-like, with very low electrical and acoustic loss. We estimate that this transducer can realize an intrinsic conversion efficiency of up to 35% with <0.5 added noise quanta when resonantly coupled to a superconducting transmon qubit and operated in pulsed mode at 10 kHz repetition rate. The performance improvement gained in such hybrid lithium niobate-silicon transducers make them suitable for heralded entanglement of qubits between superconducting quantum processors connected by optical fiber links.
Pointwise eigenfunction estimates and intrinsic ultracontractivity-type properties of Feynman-Kac semigroups for a class of Lévy processes

description: We introduce a class of Lévy processes subject to specific regularity conditions, and consider their Feynman-Kac semigroups given under a Kato-class potential. Using new techniques, first we analyze the rate of decay of eigenfunctions at infinity. We prove bounds on $λ$-subaveraging functions, from which we derive two-sided sharp pointwise estimates on the ground state, and obtain upper bounds on all other eigenfunctions. Next, by using these results, we analyze intrinsic ultracontractivity and related properties of the semigroup refining them by the concept of ground state domination and asymptotic versions. We establish the relationships of these properties, derive sharp necessary and sufficient conditions for their validity in terms of the behavior of the Lévy density and the potential at infinity, define the concept of borderline potential for the asymptotic properties and give probabilistic and variational characterizations. These results are amply illustrated by key examples.

description: Introduction: On November 18th, NLM marks the 50th anniversary of the Medical Subject headings (MeSH).

MeSH was first published in 1960, although its seeds planted in December 1947; it was noted that the increasing complexity of medical scientific literature necessitated increasingly sophisticated approaches to organization and access.

Medical Subject Headings has translation into Spanish and Portuguese known as Health Sciences Descriptors (DeCS), trilingual and structured vocabulary created in the 1960’s by BIREME (Latin American and Caribbean Center on Health Sciences Information).

Material and methods: Spain collaborates with this project since 2003 and through its Surveillance Terminology Unit belonging to the Spanish National Library of Health Sciences (BNCS) from the Institute of Health Carlos III, which uses the work of experts in medical terminology to carry out two important tasks: from one hand, the translation into Spanish of the new terms that the NLM identifies annually and on the other hand, the revision and adaptation into Spanish of the terms already reflected in the thesaurus.

Results: The main success result of this collaboration is an updated thesaurus specialized on Health Sciences with medical terminology adapted to Spain. Appart from its applications on specialized databases, the Spanish National Library of Health Sciences (BNCS) contributes through DeCS terms in the unified terminology development project, UMLS- Unified Medical Language System of the NLM, with the responsibility of the updating and sending of new terms in Spanish.

Conclusions: This posters attempts to reflect, in a graphic way, the whole role of the Spanish National Library of Health Sciences in this project, explaining the categories already translated, the work still pending, as well as the challenges that may be considered.

Year: 2023

description: Abstract: Aging is an inevitable process that brings physical, psychological, and social challenges. The increasing elderly population demands a shift in healthcare priorities, focusing on dignity, quality of life, and community-based care. Community health nurses (CHNs) play a crucial role in addressing these concerns through preventive, curative, and rehabilitative interventions. This review explores the multifaceted approach of community nursing in elderly care, covering aspects like chronic disease management, mental health support, social inclusion, and palliative care. It highlights evidence-based strategies, global best practices, and policy implications for enhancing geriatric healthcare.

description: The study of open quantum systems (OQSs), i.e., systems interacting with an environment, impacts our understanding of exotic nuclei in low-energy nuclear physics, hadrons, cold-atom systems, or even noisy intermediate-scale quantum computers. Such systems often exhibit resonance states characterized by energy positions and dispersions (or decay widths), the properties of which can be difficult to predict theoretically due to their coupling to the continuum of scattering states. Dealing with this phenomenon poses challenges both conceptually and numerically. For that reason, we investigate how the reduced basis method known as eigenvector continuation (EC), which has emerged as a powerful tool to emulate bound and scattering states in closed quantum systems, can be used to study resonance properties. In particular, we present a generalization of EC that we call conjugate-augmented eigenvector continuation, which is based on the complex-scaling method and designed to predict Gamow-Siegert states, and thus resonant properties of OQSs, using only bound-state wave functions as input.

description: We analyze the state space of a Bianchi-I universe with anisotropic sources. Here we consider an extended state space which includes null geodesics in this background. The evolution equations for all the state observables are derived. Dynamical systems approach is used to study the evolution of these equations. The asymptotic stable fixed points for all the evolution equations are found. We also check our analytic results with numerical analysis of these dynamical equations. The evolution of the state observables are studied both in cosmic time and using a dimensionless time variable. Then we repeat the same analysis with a more realistic scenario, adding the isotropic (dust like dark) matter and a cosmological constant (dark energy) to our anisotropic sources, to study their co-evolution. The universe now approaches a de~Sitter space asymptotically dominated by the cosmological constant. The cosmic microwave background anisotropy maps due to shear are also generated in this scenario, assuming that the universe contains anisotropic matter along with the usual (dark) matter and vacuum (dark) energy since decoupling. We find that they contribute dominantly to the CMB quadrupole. We also constrain the current level of anisotropy and also search for any cosmic preferred axis present in the data. We use the Union~2 Supernovae data to this extent. An anisotropy axis close to the mirror symmetry axis seen in the cosmic microwave background data from Planck probe is found.

description: We study the single-channel source separation problem involving orthogonal frequency-division multiplexing (OFDM) signals, which are ubiquitous in many modern-day digital communication systems. Related efforts have been pursued in monaural source separation, where state-of-the-art neural architectures have been adopted to train an end-to-end separator for audio signals (as 1-dimensional time series). In this work, through a prototype problem based on the OFDM source model, we assess -- and question -- the efficacy of using audio-oriented neural architectures in separating signals based on features pertinent to communication waveforms. Perhaps surprisingly, we demonstrate that in some configurations, where perfect separation is theoretically attainable, these audio-oriented neural architectures perform poorly in separating co-channel OFDM waveforms. Yet, we propose critical domain-informed modifications to the network parameterization, based on insights from OFDM structures, that can confer about 30 dB improvement in performance.
Singlet Extension of the MSSM for 125 GeV Higgs Mass with the Least Tuning

description: In order to raise the Higgs mass up to 125 GeV and relieve the fine-tuning associated with the heavy s-top mass in the minimal supersymmetric standard model (MSSM), we propose a new singlet extension of the MSSM. In this scenario, the additional Higgs mass is radiatively generated also in a hidden sector, and the effect is tansmitted to the Higgs through a messenger field. The Higgs mass can be efficiently increased by the parameters of the superpotential as in the extra matter scenario, but free from the constraints on extra colored matter fields by the LHC experiments. As a result, the tuning problem can be remarkably mitigated by taking low enough messenger mass (\sim 300 GeV) and mass parameter scales (\sim 500 GeV).

description: I study the design and construction of modern spectrographs and use spectrographs to study the properties of galaxies in a local galaxy redshift survey and to study the structure of our own Galaxy from a stellar radial velocity survey.  I perform four scientific studies based on 64 square degrees of deep V- and R-band imaging I obtained with the 8 CCD Mosaic camera on the Kitt Peak National Observatory 0.9 m telescope.  I study 1) the local galaxy luminosity function, 2) low surface brightness galaxies, 3) UV excess galaxies, and 4) the structure of the Galactic halo.

I find surprisingly identical V- and R-band faint end slopes of the local galaxy luminosity function, α=-1.07 \pm 0.09, and local luminosity densities in essential agreement with the recent 2dF and SDSS determinations. All low surface brightness galaxies fall in the large scale structure delineated by high surface brightness galaxies and contribute little to the total luminosity density of the local Universe.  I show that a sample of ultraviolet (UV) excess galaxies are likely Wolf-Rayet galaxies, starburst galaxies with strong UV emission lines that can double or triple the flux through the UV bandpass at large redshifts and can skew the selection function to large redshifts.  I use blue horizontal branch stars to trace the structure of the Milky Way halo and find evidence for systematic motions in the inner halo as well as a probable star stream 6 \pm 1.4 kpc above the Galactic plane.

My instrumentation work includes a detailed thermal analysis of Binospec, a wide-field, multi-object spectrograph for the MMT.  I find that a well-insulated spectrograph design will have a time constant of 36 hours, leading to ~0.1 deg C temperature gradients in the refractive optics and ~0.1 pixel/hr image shifts at the detector.

description: A system of identical disks is confined to a narrow channel, closed off at one end by a stopper and at the other end by a piston. All surfaces are hard and frictionless. A uniform gravitational field is directed parallel to the plane of the disks and perpendicular to the axis of the channel. We employ a method of configurational statistics that interprets jammed states as configurations of floating particles with structure. The particles interlink according to set rules. The two jammed microstates with smallest volume act as pseudo-vacuum. The placement of particles is subject to a generalized Pauli principle. Jammed macrostates are generated by random agitations and specified by two control variables. One is a measure of the intensity of random agitations at given pressure. The other is a measure of the change in gravitational potential energy in units of compression work when one particle is excited. In this two-dimensional space of variables there exists a critical point. The jammed macrostate realized at the critical point depends on the path of approach. We describe all jammed macrostates by volume and entropy. Both are functions of the average population densities of particles. Approaching the critical point in an extended space of control variables generates two types of jammed macrostates: states with random heterogeneities in mass density and states with domains of uniform mass density.

Subjects: The Theory of Everything: Cosmic Resistance as a Unifying Framework for Fundamental Physics

description:  

This paper introduces cosmic resistance () as a fundamental principle that unifies cosmology, quantum mechanics, and fundamental forces. By modifying Einstein’s mass-energy equivalence () and integrating cosmic resistance into the Friedmann equations, we present an alternative explanation for dark energy and cosmic expansion. Additionally, we explore how cosmic resistance affects quantum field theory (QFT), quantum chromodynamics (QCD), electromagnetism, and gravity, influencing the fine-structure constant, Higgs mechanism, and quark-gluon interactions. The paper proposes observational and experimental tests, including gravitational lensing, cosmic microwave background (CMB) anomalies, and high-energy particle physics experiments, to validate the theory. This work provides a bold step toward the unification of the fundamental laws of nature, offering a new perspective on the elusive Theory of Everything.

description: Salinity causes reduction in growth and severe losses of crop productivity by affecting various biochemical and physiological processes including photosynthesis. Plants sense and adapt to salt stress by modulating different physiological processes including accumulation of osmoprotectants. Glycinebetaine (GB) is an important osmoprotectant and found to have ameliorative effects on the growth of plants by altering ion homeostasis, photosynthetic and antioxidant capacity. In this study, it was attempted to reveal how GB improves photosynthetic activity and salt tolerance of two canola cultivars which differ in degree of salt tolerance. Two cultivars (Dunkled and Cyclone) of canola (Brassica napus L.) were grown under non-saline or saline (150 mM NaCl) conditions. Glycinebetaine (100 mM) was foliarly applied to both non-stressed and salt stressed plants of both canola cultivars at the vegetative growth stage. Salt stress reduced growth of both canola cultivars, however, cv. Dunkled was superior to cv. Cyclone. Foliar application of GB improved leaf relative water contents (RWC), osmotic potential and proline accumulation in salt stressed plants. The chlorophyll fluorescence transient (CFT) remained unchanged at O and J phase while at I and P phase it was affected by salt stress in both cultivars that was ameliorated by GB application. The positive values of K band after 1000 µs under salt stress revealed the reduced efficiency of oxygen evolving complex (OEC). The GB application enhanced electron transport chain and decreased heat dissipation under salt stress. This effect was more in cultivar Cyclone as compared to Dunkled. Furthermore, a considerable proteomic variation was noted in canola cultivars after application of GB under both saline and non-saline condition. The results suggested that exogenous foliar application of GB ameliorated the adverse effects of salt stress on both cultivars of canola by osmotic adjustment, growth improvement, increased light absorption by reaction centers, efficient energy trapping and enhanced electron transport chain in both cultivars of canola.

description: Molecular magnets have received significant attention because of their potential applications in quantum information and quantum computing. A delicate balance of electron correlation, spin-orbit coupling (SOC), ligand field splitting, and other effects produces a persistent magnetic moment within each molecular magnet unit. The discovery and design of molecular magnets with improved functionalities would be greatly aided by accurate computations. However, the competition among the different effects poses a challenge for theoretical treatments. Electron correlation plays a central role, since d-, or f-element ions, which provide the magnetic states in molecular magnets, often require explicit many-body treatments. SOC, which expands the dimensionality of the Hilbert space, can also lead to non-perturbative effects in the presence of strong interaction. Furthermore, molecular magnets are large, with tens of atoms in even the smallest systems. We show how an $\textit{ab initio}$ treatment of molecular magnets can be achieved with auxiliary-field quantum Monte Carlo (AFQMC), in which electron correlation, SOC, and material specificity are included accurately and on an equal footing. The approach is demonstrated by an application to compute the zero-field splitting of a locally-linear Co$^{2+}$ complex.

description: One of the most important properties of quantum information, and the one ultimately responsible for its cryptographic applications, is that it can't be copied. That statement, however, is not completely accurate. While the no-cloning theorem of quantum mechanics prevents quantum information from being copied in space, the reversibility of microscopic physics actually requires that the information be copied in time. In spacetime as a whole, therefore, quantum information is widely replicated but in a restricted fashion. We fully characterize which regions of spacetime can all hold the same quantum information. Because quantum information can be delocalized through quantum error correction and teleportation, it need not follow well-defined trajectories. Instead, replication of the information in any configuration of spacetime regions not leading to violations of causality or the no-cloning principle is allowed. To demonstrate this, we answer the operational question of exactly when the information can be summoned to a set of spacetime points, showing how to do so efficiently using a combination of teleportation and codeword-stabilized quantum codes. This provides a simple and complete description of where and when a qubit can be located in spacetime, revealing a remarkable variety of possibilities.

The juice-to-fruit-weight ratio and solids-to-acid ratio were calculated from the individual factors. Considerable differences between these characteristics by country of origin were found.

description: The effects of rain cover on tree yield, fruit cracking and quality ,of two cherry (Prunus avium L.) cultivars, ‘Adriana’ and ‘Noire de Meched’ (‘NM’), were investigated. Cherry quality was determined at harvest and after storage at 1°C in air for up to 21 d. Rates of CO2 production and O2 uptake were determined at weekly intervals during and after storage. A taste panel rated quality attributes of ‘NM’ after 14 d storage. The results showed that ‘Adriana’ was completely, but ‘NM’ moderately resistant to cracking, while covering prevented the symptom. Respiration rates showed immediate and continuous cooling requirements of all fruit. In ‘Adriana’, covering reduced weight loss during the first 7-d storage, and promoted the peel colour (PC) and total soluble solids subsequently. Under different environmental conditions, PC and total phenolics were advanced in uncovered ‘NM’ at harvest and after storage. In both cultivars, covering did not affect negatively the yield, nor did it significantly the fruit weight, firmness, titratable acidity, pH value, total antioxidant activity, stem browning and resistance to stem removal. ‘Adriana’ and ‘NM’ retained good quality for 21 and 14 d storage, respectively.

description: DANTE is a new Digital Pulse Processor (DPP) developed for fluorescence detectors, like silicon drift detectors (SDDs) or High Purity Germanium detectors (HPGe), used in X-ray Fluorescence (XRF) and X-ray Absorption Spectroscopy (XAS) experiments at synchrotron facilities. Its main features are its optimal energy resolution and peak stability for detector count rate values up to 1-2 Mcps, and its enhanced rejection of pile-up events. In this paper, we present the first complete evaluation of DANTE performance in SOLEIL synchrotron facility. DANTE has been tested in laboratory with an X-ray generator source and in different experiments at LUCIA and PUMA beamlines at SOLEIL.

description: We define pseudo-Riemannian spectral triples, an analytic context broad enough to encompass a spectral description of a wide class of pseudo-Riemannian manifolds, as well as their noncommutative generalisations. Our main theorem shows that to each pseudo-Riemannian spectral triple we can associate a genuine spectral triple, and so a K-homology class. With some additional assumptions we can then apply the local index theorem. We give a range of examples and some applications. The example of the harmonic oscillator in particular shows that our main theorem applies to much more than just classical pseudo-Riemannian manifolds.
Monomial projections of Veronese varieties: new results and conjectures

description: In this paper, we consider the homogeneous coordinate rings $A(Y_{n,d}) \cong \mathbb{K}[Ω_{n,d}]$ of monomial projections $Y_{n,d}$ of Veronese varieties parameterized by subsets $Ω_{n,d}$ of monomials of degree $d$ in $n+1$ variables where: (1) $Ω_{n,d}$ contains all monomials supported in at most $s$ variables and, (2) $Ω_{n,d}$ is a set of monomial invariants of a finite diagonal abelian group $G \subset GL(n+1,\mathbb{K})$ of order $d$. Our goal is to study when $\mathbb{K}[Ω_{n,d}]$ is a quadratic algebra and, if so, when $\mathbb{K}[Ω_{n,d}]$ is Koszul or G-quadratic. For the family (1), we prove that $\mathbb{K}[Ω_{n,d}]$ is quadratic when $s \ge \lceil \frac{n+2}{2} \rceil$. For the family (2), we completely characterize when $\mathbb{K}[Ω_{2,d}]$ is quadratic in terms of the group $G \subset GL(3,\mathbb{K})$, and we prove that $\mathbb{K}[Ω_{2,d}]$ is quadratic if and only if it is Koszul. We also provide large families of examples where $\mathbb{K}[Ω_{n,d}]$ is G-quadratic.

description: We give a geometric description of the set of holes in a non-normal affine monoid $Q$. The set of holes turns out to be related to the non-trivial graded components of the local cohomology of $k[Q]$. From this, we see how various properties of $k[Q]$ like local normality and Serre's conditions $(R_1)$ and $(S_2)$ are encoded in the geometry of the holes. A combinatorial upper bound for the depth the monoid algebra $k[Q]$ is obtained and some cases where equality holds are identified. We apply this results to seminormal affine monoids.

Illustrating a neural model of logic computations: The case of Sherlock Holmes' old maxim

description: Natural languages can express some logical propositions that humans are able to understand. We illustrate this fact with a famous text that Conan Doyle attributed to Holmes: 'It is an old maxim of mine that when you have excluded the impossible, whatever remains, however improbable, must be the truth'. This is a subtle logical statement usually felt as an evident truth. The problem we are trying to solve is the cognitive reason for such a feeling. We postulate here that we accept Holmes' maxim as true because our adult brains are equipped with neural modules that naturally perform modal logical computations.

Conformal bootstrap in momentum space at finite volume

Year: 2023
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: In this paper, we Fourier transform the Wightman function concerning energy and angular momentum on the $S^{D-1}$ spatial slice in radial quantization in $D=2,3$ dimensions. In each case, we use the conformal Ward Identities to solve systematically for the Fourier components. We then use these Fourier components to build conformal blocks for the four-point function in momentum space, giving a finite-volume version of the momentum-space conformal blocks. We check that this construction is consistent with the known result in infinite volume. Our construction may help to find bootstrap equations that can give nontrivial constraints that do not appear in analysis in infinite volume. We show some examples of bootstrap equations and their nontriviality.

Proximity effect and spatial Kibble-Zurek mechanism in atomic Fermi gases with inhomogeneous pairing interactions

description: Introducing spatially tunable interactions to atomic Fermi gases makes it feasible to study two phenomena, the proximity effect and spatial Kibble-Zurek mechanism (KZM), in a unified platform. While the proximity effect of a superconductor adjacent to a normal metal corresponds to a step-function quench of the pairing interaction in real space, the spatial KZM is based on a linear drop of the interaction that can be modeled as a spatial quench. After formulating the Fermi gases with spatially varying pairing interactions by the Bogoliubov-de Gennes equation, we obtain the profiles of the pair wavefunction and its correlation function to study their penetration into the noninteracting region. For the step-function quench, both correlation lengths from the pair wavefunction and its correlation function follow the BCS coherence length and exhibit the same scaling behavior. In contrast, the scaling behavior of the two correlation lengths are different in the spatial quench, which then allows more refined analyses of the correlation lengths from different physical quantities. Moreover, adding a weakly interacting bosonic background does not change the scaling behavior. We also discuss relevant experimental techniques that may realize and verify the inhomogeneous phenomena.
