description: Monolayer transition metal dichalcogenides (TMDs) exhibit a remarkably strong Coulomb interaction that manifests in tightly bound excitons. Due to the complex electronic band structure exhibiting several spin-split valleys in the conduction and valence band, dark excitonic states can be formed. They are inaccessibly by light due to the required spin-flip and/or momentum transfer. The relative position of these dark states with respect to the optically accessible bright excitons has a crucial impact on the emission efficiency of these materials and thus on their technological potential. Based on the solution of the Wannier equation, we present the excitonic landscape of the most studied TMD materials including the spectral position of momentum- and spin-forbidden excitonic states. We show that the knowledge of the electronic dispersion does not allow to conclude about the nature of the material's band gap, since excitonic effects can give rise to significant changes. Furthermore, we reveal that an exponentially reduced photoluminescence yield does not necessarily reflect a transition from a direct to a non-direct gap material, but can be ascribed in most cases to a change of the relative spectral distance between bright and dark excitonic states.

description: We re-examine the historically important decay of the neutral pion into two photons. Schwinger's Equivalence Theorem is confirmed. We then consider radiative corrections to the famous Adler-Bell-Jackiw (ABJ) anomaly. The result depends crucially on a physically motivated regularization scheme. Our approach is largely based on Schwinger's source (dispersion) method.

description: Neutron and proton densities in the nuclear periphery are investigated within (p,n) charge-exchange isobar transitions. For this purpose we have developed parameter-free optical potentials with a detailed treatment of the in-medium $t_τ$ part of the effective interaction. Non local coupled-channel Lane equations are solved to obtain the scattering observables. The use of conventional proton and neutron densities significantly underestimates Fermi (forward-angle) cross-sections in agreement with findings by various other groups. However, we have found model-independent densities which provide a remarkable improvement in the description of the quasielastic scattering data.The densities obtained are consistent with recent measurements at CERN in studies of the neutron-to-proton halo factor f(r)=Z$ρ_n/Nρ_p$ with antiprotons. These findings provide an alternative way to investigate the nuclear periphery, and may also help to solve the long-standing puzzle of the underestimated Fermi cross section in (p,n) charge-exchange phenomena.

Tau neutrinos from ultracompact dark matter minihalos and constraints on the primordial curvature perturbations

description: The observations and research on the neutrinos provide a kind of indirect way of revealing the properties of dark matter particles. For the detection of muon neutrinos, the main issue is the large atmospheric background, which is caused by the interactions between the cosmic rays and atoms within the atmosphere. Compared with muon neutrinos, tau neutrinos have a smaller atmospheric background especially for the downward-going direction. Except for the classical neutrino sources, dark matter particles can also annihilate into the neutrinos and are the potential high energy astrophysical sources. The annihilation rate of dark matter particles is proportional to the square of number density; therefore, the annihilation rate is large near the center of dark matter halos especially for the new kind of dark matter structures named ultracompact dark matter minihalos (UCMHs). In previous works, we have investigated the potential muon neutrino flux from UCMHs due to dark matter annihilation. Moreover, since the formation of UCMHs is related to the primordial density perturbations of small scales, we get the constraints on the amplitude of the primordial curvature perturbations of small scales, $1 \lesssim k \lesssim 10^{7} ~\rm Mpc^{-1}$. In this work, we focus on the downward-going tau neutrinos from UCMHs due to dark matter annihilation. Compared with the background of tau neutrino flux we get the constraints on the mass fraction of UCMHs. Then using the limits on the mass fraction of UCMHs we got the constraints on the amplitude of the primordial curvature perturbations which are extended to the scale $k \sim 10^{8} ~ \rm Mpc^{-1}$ compared with previous results.

description: Two types of MgB2 films were prepared by pulsed laser deposition (PLD) with in situ and ex situ annealing processes respectively. Significant differences in properties between the two types of films were found. The ex situ MgB2 film has a Tc of 38.1K, while the in situ film has a depressed Tc of 34.5K. The resistivity at 40K for the in situ film is larger than that of the ex situ film by a factor of 6. The residual resistivity ratios (RRR) are 1.1 and 2.1 for the in situ and ex situ films respectively. The Jc-H curves of the in situ film show a much weaker field dependence than those of the ex situ film, attributable to stronger flux pinning in the in situ film. The small-grain feature and high oxygen level may be critical for the significant improvement of Jc in the in situ annealed MgB2 film.

Classical theory of canonical QCD on a space-like hypersurface
Creators: name: Ozaki, Hiroshi
Publisher: name: arXiv
Year: 2000
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: The canonical formalism in classical theory of QCD is constructed on a space-like hypersurface. The Poisson bracket on the space-like hypersurface is defined and it plays an important role to describe every algebraic relation in the canonical formalism into Lorentz covariant form. Surface integrals are introduced as alternatives of field equations for quarks, gluons, and Faddeev-Popov ghosts. It is shown that deformations of the space-like hypersurface for surface integrals are generated by the interaction term of QCD Hamiltonian density. By converting the Poisson bracket on the space-like hypersurface to four-dimensional commutator, we can pass over to QCD in the Heisenberg picture without spoiling the explicit Lorentz covariance.

description: A new pulsating X-ray source, AX J183220-0840, with a 1549.1-s period was discovered at R.A.= 18h32m20s and Dec.=-8d40'30'' (J2000, uncertainty=0.6degree) during an ASCA observation on the Galactic plane. The source was observed two times, in 1997 and in 1999. A phase-averaged X-ray flux of 1.1E-11 ergs cm-2 s-1 and pulsation period of 1549.1+/-0.4 s were consistently obtained from these two observations. The X-ray spectrum was represented by a flat absorbed power-law with a photon-index of =~0.8 and an absorption column density of =~1.3E22 cm-2. Also, a signature of iron K-shell line emission with a centroid of 6.7 keV and an equivalent width of approximately 450 eV was detected. From the pulsation period and the iron-line feature, AX J183220-0840 is likely to be a magnetic white dwarf binary with a complexly absorbed thermal spectrum with a temperature of about 10 keV.

description: The in-medium mass of a $\thetaplus$, $\mtheta^*$, in cold symmetric nuclear matter is calculated by using the quark-meson coupling model. The $Θ^+$ is treated as an MIT bag with the quark content $uudd\bar s$. Bag parameters for a free $\thetaplus$ are fixed to reproduce the observed mass of the $\thetaplus$. In doing so, we use three different values of the $s$-quark mass since the mass of the $s$-quark is not well known. As usual, the strengths of the $u$ and $d$ quark couplings to $σ$- and $ω$-meson fields are determined to fit the nuclear saturation properties. However, the coupling constant $g_σ^s$ between the $s$-quark and the $σ$-meson cannot be fixed from the saturation properties, and thus we treat $g_σ^s$ as a free parameter and investigate how $\mtheta^*$ depends on $g_σ^s$. %$\mtheta^*$ is calculated up to 2.5 times the nuclear saturation density, %and we find that We find that $\mtheta^*$ depends significantly on the value of $g_σ^s$ but not on the mass of the $s$-quark. Chemical potentials of the $Θ^+$ and the $K+N$ system are calculated to discuss the decay of a $Θ^+$ in nuclear matter. We calculate the effective mass of a kaon in nuclear matter in two ways; using the optical potential of $K^-$ in matter and using quark model. By comparing the effective masses calculated from these two methods, we find the magnitude of the real part of the optical potential that is consistent with the usual quark model is about 100 MeV.

description: The paper explores the integration of these technologies to create a comprehensive solution for amplitude modulation and demodulation in communication systems. FPGA, represented by the Xilinx Vivado design suite, is used to generate the carrier signal, perform the modulation and demodulation operations, and handle the digital signal processing.GNU Radio, an open-source software development toolkit, is utilized to simulate and test the modulation and demodulation algorithms before implementation on the FPGA. The SDR hardware, such as USRP or HackRF One, is employed to generate and process the analog signals, while the FPGA and GNU Radio handle the digital signal processing tasks.The workflow involves designing the amplitude modulation and demodulation algorithms in Vivado, simulating and testing them using GNU Radio and the SDR hardware, and then implementing the FPGA-based system integrated with the SDR platform. This approach allows for a flexible and powerful implementation of amplitude modulation and demodulation, leveraging the strengths of FPGA hardware, GNU Radio software, and SDR platforms to create a comprehensive communication system. This work explores the simulation and spoofing of GPS signals using SDR technology. The objective is to generate simulated GPS signals and successfully lock them onto a GPS user receiver, effectively spoofing the receiver.

description: The charge transport of electron doped Mott insulators on a triangular lattice is investigated within the t-J model based on the partial charge-spin separation fermion-spin theory. The conductivity spectrum shows a low-energy peak and the unusual midinfrared band, while the resistivity is characterized by a crossover from the high temperature metallic-like to the low temperature insulating-like behavior, in qualitative agreement with experiments. Our results also show that the mechanism that cause this unusual charge transport is closely related with a competition between the kinetic energy and magnetic energy in the system.

description: How can dense biological tissue maintain sharp boundaries between coexisting cell populations? We explore this question within a simple vertex model for cells, focusing on the role of topology and tissue surface tension. We show that the ability of cells to independently regulate adhesivity and tension, together with neighbor-based interaction rules, lets them support strikingly unusual interfaces. In particular, we show that mechanical- and fluctuation-based measurements of the effective surface tension of a cellular aggregate yield different results, leading to mechanically soft interfaces that are nevertheless extremely sharp.

description: Using the Quark-Gluon Strings Model -- combined with Regge phenomenology -- we perform a comparative analysis of $Λ$, $Σ^0$, $Λ(1520)$ and $Θ^+$ production in binary reactions induced by photon, pion and proton beams on the nucleon. We find that the existing experimental data on the $γp \to K^+ Λ$ differential and total cross sections can be described very well by the model for photon energies $1 - 16$ GeV and $-t < 2$ GeV$^2$ assuming a dominant contribution of the $K^*$ Regge trajectory. Moreover, using the same parameters we also reproduce the total $γp \to K^+ Σ^0$ and $γp \to K^+ Λ(1520)$ cross sections suggesting a 'universality' of the Regge model. In order to check the consistency of the approach we evaluate the differential and total cross sections for the reaction $π^- p \to K^0 Λ$ which is also found to be dominated by the $K^*$ Regge trajectory. Using the apparent 'universality' of the Regge model we extend our scheme to the analysis of the binary reactions $γp \to \bar{K}^0 Θ^+$, $π^- p \to K^- Θ^+$ and $pp \to Σ^+ Θ^+$ as well as the exclusive and inclusive $Θ^+$ production in the reactions $pp \to p \bar{K}^0 Θ^+$ and $pp \to Θ^+ X$. Our detailed studies demonstrate that $Θ^+$ production does not follow the 'universality' principle thus suggesting an essentially different internal structure of the exotic baryon relative to conventional hyperons or hyperon resonances.

Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.

description: A linked cluster expansion suitable for the treatment of ground-state properties of complex nuclei, as well as of various particle-nucleus scattering processes, has been used to calculate the ground-state energy, density and momentum distribution of 16-O and 40-Ca using realistic interactions. First of all, a benchmark calculation for the ground-state energy has been performed using the truncated V8' potential, and consisting in the comparison of our results with the ones obtained by the Fermi Hypernetted Chain approach, adopting in both cases the same mean field wave functions and the same correlation functions. The results exhibited a nice agreement between the two methods. Therefore, the approach has been applied to the calculation of the ground-state energy, density and momentum distributions of 16-O and 40-Ca using the full V8' potential, finding again a satisfactory agreement with the results based on more advanced approaches where higher order cluster contributions are taken into account. It appears therefore that the cluster expansion approach can provide accurate approximations for various diagonal and non diagonal density matrices, so that it could be used for a reliable evaluation of nuclear effects in various medium and high energy scattering processes off nuclear targets. The developed approach can be readily generalized to the treatment of Glauber type final state interaction effects in inclusive, semi-inclusive and exclusive processes off nuclei at medium and high energies.

description: History education is often considered boring and students have difficulty understanding its function. However, history lessons can give us an understanding of current and future events. The problem that is often forgotten is actually only related to how we can adapt to learning models that are often less suited to real conditions. This research tested a learning model called reflective learning which was then tested on students, namely Al Kautsar High School students, Bandar Lampung. In this research, researchers used a quasi-experiment, namely one class was the control and the other received treatment in the form of reflective learning model to measure the effect on historical empathy. The research results show that a reflective learning approach can effectively foster historical empathy

Auto blocking, automatic locomotive signaling, dispatching and electrical interlocking, crossing signaling devices are under construction. The most effective means of intensifying the work of railway transport, improving the use of its main complex and expensive technical means is to automate the control of the transportation process using a complex of systems for interval regulation of train traffic and ensuring its safety. The reliability of these systems, especially for high-speed lines, largely determines the rhythm of transportation and the safety of train traffic.

description: Integrated spectrophotometric properties of stellar systems are intrinsically dispersed due to the stochastic nature of the small numbers of bright stars they contain. Among clusters, only the most massive ones can be used individually for comparison with the mean properties predicted by population synthesis calculations. The appropriate minimal masses depend, among others, on the waveband or colour index studied and on age. Selected indices (near-IR CO and H2O, EW(Halpha)) are used to illustrate the asymmetric nature of the probability distribution of observable properties and their dependence on cluster mass.

description: We study the phenomenology of a light (GeV scale) sterile neutrino sector and the pseudo-Goldstone boson (not the majoron) associated with a global symmetry in this sector that is broken at a high scale. Such scenarios can be motivated from considerations of singlet fermions from a hidden sector coupling to active neutrinos via heavy right-handed seesaw neutrinos, effectively giving rise to a secondary, low-energy seesaw framework. Such scenarios allow for rich phenomenology with observable implications for cosmology, dark matter, and direct searches, involving novel sterile neutrino dark matter production mechanisms from the pseudo-Goldstone-mediated scattering or decay, modifications of BBN bounds on sterile neutrinos, suppression of canonical sterile neutrino decay channels at direct search experiments, late injection of an additional population of neutrinos in the Universe after neutrino decoupling, and measurable dark radiation at BBN or CMB decoupling.

description: One of the reasons for reduced male fertility is urogenital infections. In the urogenital tract of men and women, there are numerous microorganisms. Persisting for a long time in the urogenital tract, they may not cause any clinical manifestations, but cause sluggish inflammation that tends to spread and develop not only urethritis, prostatitis, epididymitis, orchitis, as well as a violation of the process of spermatogenesis. Мicroorganisms damaging the spermatogenic epithelium cause disruption of spermatogenesis and the appearance of abnormal and patholog�ical forms of sperm. The study included 122 patients diagnosed with a non-obstructive (NOA) form of azoospermia and 68 diagnosed patients with obstructive azoospermia (OA). Patients with a mixed form of azoospermia were not included in the study. The number of men with a history of Trichomonas infection in NOA was 1.6%, and in OA 1.5%. The frequency of detection of chlamydia by PCR in NOA was 3.3%, and in OA -2.9%. Mycoplasma in NOA was detected in 5.7%, and in OA in 2.9%. Ureaplasma was diagnosed in 12.3% in NOA and in 11.7% in OA. In NOA, gonorrhea was detected in 6.6%, and in OA in 13.2%. Herpes simplex virus type 2 was observed in 5.7% of men with NOA and in 7.3% of men with OA. Gardnerella was diagnosed in 9.0% of men with NOA and 13.3% of men with OA. The frequency of enterococci in men with azoospermia in OA is 32.3%, almost twice higher than in the PLA (17.2%). Infection of ejaculate/prostate secretion with Escherichia coli in NOA was detected in 13.1% of patients, and in OA in 23.5%. Staphylococcus aureus was detected only in patients with OA (4.4%). β-hemolytic streptococcus was detected in both NOA (7.4%) and OA (13.2%). Epidermal streptococcus is found in men only in OA 4.4%. The results obtained indicate that infections of the male urogenital tract and infection of seminal fluid or prostate juice are important factors, causing the development of NOA and OA.

Publisher: name: Constructions
Year: 2024

description: 35 years have passed since the publication of Fillmore et al. (1988), which can be seen as one of the foundational works of Construction Grammar (CxG). The present special issue celebrates this anniversary with a collection of papers that revisit influential papers or ideas from the history of constructionist approaches. In this introduction, we motivate our choice of Fillmore et al. (1988) as a seminal paper for CxG, and give a brief overview of the ideas behind this collection of papers as well as of the papers themselves.

description: We report the synthesis and structural characterisation of three mixed-metal formate perovskite families [C(NH$_2$)$_3$]M$_{1-x}$Cu$_x$(HCOO)$_3$ (M = Mn, Zn, Mg). Using a combination of infrared spectroscopy, non-negative matrix factorization, and reverse Monte Carlo refinement, we show that the Mn- and Zn-containing compounds support compositional nanodomains resembling the polar nanoregions of conventional relaxor ferroelectrics. The M = Mg family exhibits a miscibility gap that we suggest reflects the limiting behaviour of nanodomain formation.

description: Abstract. In the summer of 2023 mines and larvae of Perittia herrichiella (Herrich-Schäffer, [1855]) (Lepidoptera: Elachistidae) were found on the plant Lonicera xylosteum L. (Caprifoliaceae) in two locations in the province of Namur and one in the province of Luxembourg. This leaf miner occurs in many parts of Europe but has not yet been observed in the Benelux. In this article, general info about this species is provided, as well as some new information about bionomics. Finally, the Belgian observations are described and tips are given to distinguish P. herrichiella from other leaf miners living on the same host plant.
Single particle calculations for a Woods-Saxon potential with triaxial deformations, and large Cartesian oscillator basis

Subjects: subject: Nuclear Theory (nucl-th)

description: We present a computer program which solves the Schrodinger equation of the stationary states for an average nuclear potential of Woods-Saxon type. In this work, we take specifically into account triaxial (i.e. ellipsoidal) nuclear surfaces. The deformation is specified by the usual Bohr parameters. The calculations are carried out in two stages. In the first, one calculates the representative matrix of the Hamiltonian in the cartesian oscillator basis. In the second stage one diagonalizes this matrix with the help of subroutines of the EISPACK library. If it is wished, one can calculate all eigenvalues, or only the part of the eigenvalues that are contained in a fixed interval defined in advance. In this latter case the eigenvectors are given conjointly. The program is very rapid, and the run-time is mainly used for the diagonalization. Thus, it is possible to use a significant number of the basis states in order to insure a best convergence of the results.

A Software-Based Lock-In Measurement for Student Laboratories
Creators: name: Chuss, David T.
Publisher: name: arXiv
Year: 2017
Subjects: subject: Physics Education (physics.ed-ph)
subject: FOS: Physical sciences

description: A student laboratory experiment is presented that introduces the concept of a lock-in measurement through the exploration of the relationship between the power detected from a modulated light source and the distance between the source and the detector. The lock-in measurement is done in software using time streams for both the reference and the detector signals. The achievable experimental sensitivity is shown to increase several orders of magnitude over the simple case without using modulation. In addition, the student becomes familiar with computational techniques pertinent to large data sets.

Building causal graphs from statistical data in the presence of latent variables
Creators: name: Spirtes, Peter

description: Abstract: "The problem of inferring causal relations from statistical data in the absence of experiments arises repeatedly in many scientific disciplines, including sociology, economics, epidemiology, and psychology. In addition, the building of expert systems could be expeditedif background knowledge elicited from experts could be supplemented with automated techniques using relevant statistics. Recently, efficientalgorithms for determining causal relationships between random variables (in the form of Bayesian networks) from appropriate statistical data when there are no unmeasured or 'latent' variables have been discovered. (See Spirtes, Glymour and Schneines 1990, Spirtes and Glymour 1991, Verma and Pearl 1990, and Pearl and Verma 1991.)Inferring causal relations when unmeasured variables are also acting is a much more difficult problem. In many cases it is impossible to infer the structure among the latent variables from statistical relations among the measured variables. But the presence of latent variablescan also make it difficult to infer the causal relations among the measured variables themselves. When only two variables, A and B, have been measured, and there is a correlation between the two, this does not suffice to establish whether A causes B, B causes A, or there is a third unmeasured variable causing both A and B. Nevertheless, when other variables are measured, more knowledge about the causal relations between A and B is possible.We will prove in Theorem 2 that there are some circumstances in which it is possible to establish that A causes B, rather than that B causesA, or that a third unmeasured variable causes both A and B; and we will prove in Theorem 3 that there are other circumstances in which the possibility that A causes B can be eliminated."
Axiomatizations of inconsistency indices for triads

description: Pairwise comparison matrices often exhibit inconsistency, therefore many indices have been suggested to measure their deviation from a consistent matrix. A set of axioms has been proposed recently that is required to be satisfied by any reasonable inconsistency index. This set seems to be not exhaustive as illustrated by an example, hence it is expanded by adding two new properties. All axioms are considered on the set of triads, pairwise comparison matrices with three alternatives, which is the simplest case of inconsistency. We choose the logically independent properties and prove that they characterize, that is, uniquely determine the inconsistency ranking induced by most inconsistency indices that coincide on this restricted domain. Since triads play a prominent role in a number of inconsistency indices, our results can also contribute to the measurement of inconsistency for pairwise comparison matrices with more than three alternatives.
