description: Sex steroid hormones occur in the bivalve tissues. Testosterone (T), various oestrogens, and progesterone have been reported in this group of organisms and the amounts of these hormones have been correlated with seasonal variation and reproduction. Yet, neither the role nor the origins of sex steroids are fully clarified. Thus, we tested the hypothesis that, apart from the esterification process, the aromatisation of androgens to oestrogens can help balance T levels during gonadal development in both sexes using Mytilus edulis trossulus as a model species. The highest testosterone concentrations were found in developed male and female gonads (IV reproductive stage of gametogenesis). The highest aromatisation efficiency was also found in the developed male and female gonads, but also in the gills. During the other stages of gametogenesis (II, III, V-I), a decrease in both testosterone concentration and aromatisation efficiency was observed in the gonads of males and females, as well as in the gills of males. However, the decrease in testosterone concentration did not affect the 17β-oestradiol concentration in mussel tissues. Thus, together with the esterification process, the ongoing aromatisation in bivalve tissues may help keeping balanced T levels.

description: Communication is a vital tool that enables interaction among people. The information and communication technology revolution has resulted in easy and free access to various social media sites that allow users to receive and send messages. However, because this revolution has altered the information world, it also threatens effective communication. This study examined the effect of social media English on students' spelling ability. The researchers recommended that for students to achieve effective communication, they should maintain the habit of clarity in their written communication and not rely on social media English.

description: Resumen
Varias especies del género Bacillus, como Bacillus azotofixans, B. subtilis, B. circulans, B. velezensis, B. coagulans, B. macerans, etc., han sido identificadas como bacterias promotoras del crecimiento de las plantas [1], éstas confieren protección a la planta contra el estrés ambiental y/o promueven el crecimiento de las plantas [2]. 
Los factores de estrés de las plantas se clasifican principalmente en dos grupos: estrés biótico y abiótico. El estrés biótico es el resultado de las interacciones entre la planta y otro organismo vivo (como insectos o microorganismos fitopatógenos incluyendo hongos, bacterias o virus), que resulta en un daño parcial; que la planta puede superar, o bien en daños significativos letales. El estrés abiótico, es el resultado de cambios en factores no biológicos, principalmente ambientales o nutricionales, que afectan el crecimiento, la reproducción o la vida de la planta (entre los que se encuentra temperaturas extremas, sequia, salinidad, presencia de metales pesados, entre otros) [3]. Los factores de estrés abióticos y bióticos son de las principales causas de deficiencias en el rendimiento, daño a los cultivos y alteraciones en las tasas de crecimiento de las plantas [2, 4]. 
Se han encontrado varios mecanismos de Bacillus spp. involucrados en la protección de las plantas contra el estrés abiótico y biótico, entre los que se incluyen [2]:
• Producción de fitohormonas.
• Mecanismos de desintoxicación de ROS.
• Quelación de metales.
• Uso de compuestos orgánicos volátiles (COV).
• Formación de biofilms.
• Colonización y competencia por espacio y nutrientes.
• Producción de antimicrobianos.
• Activación del ISR (Resistencia Sistémica Inducida).

description: Driving nanomagnets by spin-polarized currents offers exciting prospects in magnetoelectronics, but the response of the magnets to such currents remains poorly understood. We show that an averaged equation describing the diffusion of energy on a graph captures the low-damping dynamics of these systems. From this equation we obtain the bifurcation diagram of the magnets, including the critical currents to induce stable precessional states and magnetization switching, as well as the mean times of thermally assisted magnetization reversal in situations where the standard reaction rate theory of Kramers is no longer valid. These results match experimental observations and give a theoretical basis for a Néel-Brown-type formula with an effective energy barrier for the reversal times.

description: We analytically investigate the role of entanglement in time-optimal state evolution as an appli- cation of the quantum brachistochrone, a general method for obtaining the optimal time-dependent Hamiltonian for reaching a target quantum state. As a model, we treat two qubits indirectly cou- pled through an intermediate qubit that is directly controllable, which represents a typical situation in quantum information processing. We find the time-optimal unitary evolution law and quantify residual entanglement by the two-tangle between the indirectly coupled qubits, for all possible sets of initial pure quantum states of a tripartite system. The integrals of the motion of the brachistochrone are determined by fixing the minimal time at which the residual entanglement is maximized. Entan- glement plays a role for W and GHZ initial quantum states, and for the bi-separable initial state in which the indirectly coupled qubits have a nonzero value of the 2-tangle.

description: In this paper, we study an extension of the standard model with a vector-like generation of leptons. This model provides a viable dark matter candidate and a possibility to enhance the Higgs decay rate into a pair of photons. We evaluate constraints from electroweak precision tests and from vacuum stability, and find that the latter provide an upper limit on the lepton Yukawa couplings. A large enhancement of the Higgs di-photon rate can therefore only be obtained when the mass of the lightest charged lepton is close to the LEP limit. The relic density constraint suggests a co-annihilation scenario with a small mass difference between the lightest charged and neutral leptons, which also weakens the LEP limit on the lightest charged lepton mass and allows for larger Higgs di-photon decay rates. Cross sections for direct detection of the dark matter candidate are calculated, and prospects for detecting the new particles at the LHC are discussed briefly.

description: Existing literature identifies an established relationship between religiosity and health; however, one limitation is generalizability, since much of the existing normative data is based on White, English-speaking populations. To aid in measuring religiosity within Spanish-speaking populations, we have translated the adapted Religious Belief Salience Scale (Blaine & Crocker, 1995) into the Mexican dialect of Spanish, using established three-layer translation process. To assess the utility of the translated scale, we will recruit two-hundred and sixty-five adults through Amazon’s M*Turk platform. Participants will include adults (ages 18 and above) that live in the United States, speak Mexican Spanish, have used tobacco daily within the last six months, and have had an interaction with medical personnel in the last six months. Measures will include basic demographic information; religiosity, assessed by the translated version of the Religious Belief Salience Scale (RBS; Blaine & Crocker, 1995); smoking practices and characteristics, assessed by the Heaviness of Smoking Index (HSI; Heatherton et al., 1991); and intervention characteristics. The questionnaire will include open-ended questions and 10 attention checks. IP addresses will be verified to ensure participant is located within the United States at the time participation in the study.

We show that an algorithmic interpretation may also be given for a noncommutative generalization of the Grothendieck inequality due to Pisier and Haagerup. Our main result, an efficient rounding procedure for this inequality, leads to a polynomial-time constant-factor approximation algorithm for an optimization problem which generalizes the Cut Norm problem of Frieze and Kannan, and is shown here to have additional applications to robust principal component analysis and the orthogonal Procrustes problem.

description: Given two polygonal curves in the plane, there are many ways to define a notion of similarity between them. One popular measure is the Fréchet distance. Since it was proposed by Alt and Godau in 1992, many variants and extensions have been studied. Nonetheless, even more than 20 years later, the original $O(n^2 \log n)$ algorithm by Alt and Godau for computing the Fréchet distance remains the state of the art (here, $n$ denotes the number of edges on each curve). This has led Helmut Alt to conjecture that the associated decision problem is 3SUM-hard. In recent work, Agarwal et al. show how to break the quadratic barrier for the discrete version of the Fréchet distance, where one considers sequences of points instead of polygonal curves. Building on their work, we give a randomized algorithm to compute the Fréchet distance between two polygonal curves in time $O(n^2 \sqrt{\log n}(\log\log n)^{3/2})$ on a pointer machine and in time $O(n^2(\log\log n)^2)$ on a word RAM. Furthermore, we show that there exists an algebraic decision tree for the decision problem of depth $O(n^{2-\varepsilon})$, for some $\varepsilon > 0$. We believe that this reveals an intriguing new aspect of this well-studied problem. Finally, we show how to obtain the first subquadratic algorithm for computing the weak Fréchet distance on a word RAM.

description: We consider the problem of identifying whether findings replicate from one study of high dimension to another, when the primary study guides the selection of hypotheses to be examined in the follow-up study as well as when there is no division of roles into the primary and the follow-up study. We show that existing meta-analysis methods are not appropriate for this problem, and suggest novel methods instead. We prove that our multiple testing procedures control for appropriate error-rates. The suggested FWER controlling procedure is valid for arbitrary dependence among the test statistics within each study. A more powerful procedure is suggested for FDR control. We prove that this procedure controls the FDR if the test statistics are independent within the primary study, and independent or have dependence of type PRDS in the follow-up study. For arbitrary dependence within the primary study, and either arbitrary dependence or dependence of type PRDS in the follow-up study, simple conservative modifications of the procedure control the FDR. We demonstrate the usefulness of these procedures via simulations and real data examples.

It finds that these elements and fluids are repeatedly recycled with some loss to the overlying volcanic plumbing system. Pressure-temperature conditions controlling the mobilsation of cobalt are identified. It also examines how the unique properties of subduction zone fluids control the geochemistry of source regions of ore deposits in volcanic arcs.

description: We consider an abelian N=4 super Yang-Mills theory coupled to background N=4 conformal supergravity fields. At the classical level, this coupling is invariant under global SU(1,1) transformation of the complex ("dilaton-axion") supergravity scalar combined with an on-shell vector-vector duality. We compute the divergent part of the corresponding quantum effective action found by integrating over the super Yang-Mills fields and demonstrate its SU(1,1) invariance. This divergent part related to the conformal anomaly is one-loop exact and should be given by the N=4 conformal supergravity action containing the Weyl tensor squared term. This allows us to determine the full non-linear form of the bosonic part of the N=4 conformal supergravity action which has manifest SU(1,1) invariance.

description: The Tutte polynomial of a graph is a 2-variable polynomial which is quite important in both combinatorics and statistical physics. It contains various numerical invariants and polynomial invariants, such as the number of spanning trees, the number of spanning forests, the number of acyclic orientations, the reliability polynomial, chromatic polynomial and flow polynomial. In this paper, we study and gain recursive formulas for the Tutte polynomial of pseudofractal scale-free web (PSW) which implies logarithmic complexity algorithm is obtained to calculate the Tutte polynomial of PSW although it is NP-hard for general graph. We also obtain the rigorous solution for the the number of spanning trees of PSW by solving the recurrence relations derived from Tutte polynomial, which give an alternative approach for explicitly determining the number of spanning trees of PSW. Further more, we analysis the all-terminal reliability of PSW and compare the results with that of Sierpinski gasket which has the same number of nodes and edges with PSW. In contrast with the well-known conclusion that scale-free networks are more robust against removal of nodes than homogeneous networks (e.g., exponential networks and regular networks). Our results show that Sierpinski gasket (which is a regular network) are more robust against random edge failures than PSW (which is a scale-free network). Whether it is true for any regular networks and scale-free networks, is still a unresolved problem.

description: The ALICE collaboration has made the first measurement at the LHC of J/$ψ$ photoproduction in ultra-peripheral Pb-Pb-collisions at $\sqrt{s_{\rm NN}}$ = 2.76 TeV. The J/$ψ$ is identified via its dimuon decay in the forward rapidity region with the muon spectrometer for events where the hadronic activity is required to be minimal. The analysis is based on an event sample corresponding to an integrated luminosity of about 55 $μ$b$^{-1}$. The cross section for coherent J/$ψ$ production in the rapidity interval $-3.6 < y < -2.6$ is measured to be d$σ$/d$y = 1.00 \pm 0.18$ (stat) $+0.24/-0.26$ (syst) mb. The result is compared to theoretical models for coherent J/$ψ$ production and found to be in good agreement with models which include nuclear gluon shadowing.

description: Due to its reduced communication overhead and robustness to failures, distributed energy management is of paramount importance in smart grids, especially in microgrids, which feature distributed generation (DG) and distributed storage (DS). Distributed economic dispatch for a microgrid with high renewable energy penetration and demand-side management operating in grid-connected mode is considered in this paper. To address the intrinsically stochastic availability of renewable energy sources (RES), a novel power scheduling approach is introduced. The approach involves the actual renewable energy as well as the energy traded with the main grid, so that the supply-demand balance is maintained. The optimal scheduling strategy minimizes the microgrid net cost, which includes DG and DS costs, utility of dispatchable loads, and worst-case transaction cost stemming from the uncertainty in RES. Leveraging the dual decomposition, the optimization problem formulated is solved in a distributed fashion by the local controllers of DG, DS, and dispatchable loads. Numerical results are reported to corroborate the effectiveness of the novel approach.

Year: 2025

description: This article provide information about  listening comprehension is a major challenge for ESL and EFL students, often due to limited exposure to natural speech, diverse accents, and rapid speaking rates. This study examines effective methods to enhance listening skills in both learning environments. This topic is significant because listening is a key component of communication, academic achievement, and overall language proficiency. Weak listening abilities can hinder progress in speaking, reading, and writing. The issue addressed is the insufficient focus on listening instruction in many language programs, where grammar and vocabulary are often prioritized. This research explores practical approaches such as incorporating authentic audio, interactive activities, and digital tools to strengthen listening comprehension. By implementing these strategies, educators can better equip students to overcome listening difficulties and develop stronger English proficiency.

Contrary to usual perturbation theory, we perform an expansion in the branching rate around the non trivial Pure Annihilation model, whose correlation and response function we compute exactly. With this, the non-universal threshold value for having a phase transition in the simplest system belonging to the Directed Percolation universality class is found to coincide with previous Non Perturbative Renormalization Group approximate results. We also show that the Parity Conserving universality class has an unexpected RG fixed point structure, with a PA fixed point which is unstable in all dimensions of physical interest.

description: To elucidate referrals from sports medicine clinic (SMC) to orthopedics, consensus rates among physicians and surgeons on surgical need in these patients, and reasoning of the patients who refused to have surgery despite the recommendations by both groups in non-emergency sports injury patients. We conducted a retrospective cohort analysis by using the administrative and referral records of a sports medicine clinic for the 15 months between October 2017 and January 2019. Gender, age, diagnosis, and type of sport were compared between two groups (patients referred to orthopedics vs patients treated in SMC). Agreement between orthopedics and SMC on surgical need in those patients who were referred to orthopedics was evaluated. We additionally screened the hospital archive for surgery reports of patients recommended surgery, and, if a patient did not have a surgery record, we investigated the reasons by telephone interview and categorized these reasons. Surgical evaluation needed for 4.7% (n = 155) of the patients. Patients referred to orthopedics were younger (median: 22.0 years), mostly male (n = 119, 76.8%), and involved in contact sports (n = 108, 69.7%) (p < 0.001 for all) compared to patients treated conservatively. Majority of the consultations were made owing to certain diagnoses such as cruciate/collateral ligament sprain (n = 70, 45.2%), meniscal tear (n = 21, 13.5%), and cartilage injuries (n = 15, 9.7%). Most of the patients diagnosed with Achilles tendon rupture (n = 2, 100%) and patellar instability (n = 13, 81.3%) were referred to surgery. Orthopedics agreed with the sports medicine physicians’ opinions in most cases (n = 110, 71.0%). Thirty-four patients (30.9%) recommended surgery by the surgeon postponed/refused the treatment for various reasons or had surgery in another hospital. Most non-emergency sports injuries can be treated conservatively. Young and male patients participating in contact sports are more likely to need surgical treatment. Non-surgeon musculoskeletal health-care providers may consider referring patients to orthopedics considering the data demonstrated in this study. Nevertheless, patient’s motivation to undergo an operation should be considered before referring to orthopedics.

description: To develop and assess the test-retest reliability of a survey exploring Australian high-performance female athlete’s perspectives toward the periodic health evaluation and their perceived health needs. A structured three-phase method for survey development was used to develop the periodic health evaluation for female athletes (PHE FA) survey. Initially, a literature review and gap analysis was performed to identify themes and questions (Phase 1). Survey questions were developed covering demographic information (n = 9); sports-related medical screening (n = 19) and health needs and information (n = 7) (Phase 2). Test-retest reliability of the survey was then assessed (Phase 3). The survey was administered to a purposeful sample of seven high-performance level female athletes who completed the survey, on two separate occasions, 3 weeks apart via Checkbox© survey software (Checkbox Technology Inc., San Francisco, CA). Test-retest reliability was assessed using the intraclass correlation coefficient (ICC). The mean age of the athletes was 29 years (SD 4 years, range 24–34 years). All were able-bodied athletes and 71% participated in team sports. Eighty-six percent of athletes have competed in world championships and 71% were Olympians. The average ICC of all items was 0.998 (95% CI 0.997–0.998, p = 0.000) demonstrating excellent consistency of measures between the two time points. All the athletes preferred a Sport and Exercise Medicine Physician to conduct their PHE and 86% preferred a female doctor. The key topics of interest were pelvic floor health including incontinence (100%); fertility (86%); pregnancy (71%); and mental and emotional wellbeing (71%). Face-to-face education was the preferred option to receive health information. The PHE FA survey was co-created with an athlete and other key stakeholders. Excellent consistency of measures between the two time points was indicated by the high test-retest reliability of the PHE FA survey. Data collected using the PHE FA survey can contribute to informed evidence-based policies, and processes to support the health and wellbeing of female athletes.

description: The stressors that National Football League (NFL) athletes face are well-described and documented with regard to multisystem afflictions and injury prevalence. However, the majority of literature discusses the short-term effects rather than long-term outcomes of playing professional football. The purpose of this study was to characterize the long-term musculoskeletal issues in the retired NFL population. Publications from CENTRAL, Scopus, Medline, PubMed, Embase, and Google Scholar were searched from database inception to February 2021. A total of 9 cohort studies evaluating lower extremity arthritis in retired NFL athletes were included for review. Two reviewers extracted data from the individual studies, including demographic information (age, body mass index, length of career, position), injury descriptions (location of injury, number of injuries, diagnoses), and procedure (total knee and or hip arthroplasty) frequency. Arthritis in retired NFL players was more than twice as prevalent than the general United States male population (95% CI: 2.1–2.3). Ankle osteoarthritis was directly correlated with the number of foot and ankle injuries. Players <50 years of age had a 16.1 and 13.8 times higher risk of undergoing TKA and THA, respectively, when compared to the general population. In older age groups, this trend held with retired NFL players being at least 4.3 and 4.6 times more likely than members of the general population to undergo TKA and THA, respectively. This review demonstrates that the effects of NFL-related lower extremity injuries extend beyond the players’ careers and present a higher risk for early-onset osteoarthritis and overall frequency of undergoing total knee and hip arthroplasty.

description: We present a robust method to constrain average galaxy star formation rates, star formation histories, and the intracluster light as a function of halo mass. Our results are consistent with observed galaxy stellar mass functions, specific star formation rates, and cosmic star formation rates from z=0 to z=8. We consider the effects of a wide range of uncertainties on our results, including those affecting stellar masses, star formation rates, and the halo mass function at the heart of our analysis. As they are relevant to our method, we also present new calibrations of the dark matter halo mass function, halo mass accretion histories, and halo-subhalo merger rates out to z=8. We also provide new compilations of cosmic and specific star formation rates; more recent measurements are now consistent with the buildup of the cosmic stellar mass density at all redshifts. Implications of our work include: halos near 10^12 Msun are the most efficient at forming stars at all redshifts, the baryon conversion efficiency of massive halos drops markedly after z ~ 2.5 (consistent with theories of cold-mode accretion), the ICL for massive galaxies is expected to be significant out to at least z ~ 1-1.5, and dwarf galaxies at low redshifts have higher stellar mass to halo mass ratios than previous expectations and form later than in most theoretical models. Finally, we provide new fitting formulae for star formation histories that are more accurate than the standard declining tau model. Our approach places a wide variety of observations relating to the star formation history of galaxies into a self-consistent framework based on the modern understanding of structure formation in LCDM. Constraints on the stellar mass-halo mass relationship and star formation rates are available for download at http://www.peterbehroozi.com/data.html .

description: On a Riemannian spin manifold with
      parallel skew torsion, we use the twistor operator to obtain
      an eigenvalue estimate for the Dirac operator with torsion.
      We consider the equality case in dimensions four and six. In
      odd dimensions we describe Sasaki manifolds on which equality
      in the estimate is realized by Killing spinors with torsion.
      In dimension five we characterize all Killing spinors with
      torsion and obtain certain naturally reductive spaces as
      exceptional cases.

description: Recently developed numerical methods have enabled the explicit construction of the superconducting state of the Hubbard model of strongly correlated electrons in parameter regimes where the model also exhibits a pseudogap and a Mott insulating phase. $d_{x^2-y^2}$ symmetry superconductivity is found to occur in proximity to the Mott insulator, but separated from it by a pseudogapped nonsuperconducting phase. The superconducting transition temperature and order parameter amplitude are found to be maximal at the onset of the normal-state pseudogap. The emergence of superconductivity from the normal state pseudogap leads to a decrease in the excitation gap. All of these features are consistent with the observed behavior of the copper-oxide superconductors.

description: We prove that every self-homeomorphism $h : K_s \to K_s$ on the inverse limit space $K_s$ of the tent map $T_s$ with slope $s \in (\sqrt 2, 2]$ has topological entropy $\htop(h) = |R| \log s$, where $R \in \Z$ is such that $h$ and $σ^R$ are isotopic. Conclusions on the possible values of the entropy of homeomorphisms of the inverse limit space of a (renormalizable) quadratic map are drawn as well.
