description: Cooling flow models for the hot gas in elliptical galaxies predict that gas is cooling at a rate of ~ 1 solar mass/yr, yet there is little evidence for this phenomenon beyond the X-ray waveband. If hot gas is cooling, it will pass through the 3x10^5 K regime and radiate in the OVI 1032,1038 ultraviolet lines, which can be detected with the Far Ultraviolet Spectroscopic Explorer (FUSE) and here we report on FUSE observations of the X-ray bright early-type galaxies NGC 1404 and NGC 4636. In NGC 1404, the OVI doublet is not detected, implying a cooling rate < 0.3 solar masses/yr, which is below the predicted values from the cooling flow model of 0.4-0.9 solar masses/yr. In NGC 4636, both OVI lines are clearly detected, indicating a cooling rate of 0.43 +/- 0.06 solar masses/yr, which falls within the range of values from the cooling flow prediction, 0.36-2.3 solar masses/yr and is closest to the model where the production of the cooled gas is distributed through the galaxy. The emission line widths, 44 +/- 15 km/s, are close to the Doppler broadening value (30 km/s), indicating that the flow is quiescent rather than turbulent, and that the flow velocity is < 30 km/s.

description: Pseudomedon lecoqi COIFFAIT 1980 (Figs 5, 15-17; Map 2)
 Pseudomedon (Euphonus) lecoqi COIFFAIT 1980: 45 f.
T y p e m a t e r i a l e x a m i n e d Paratype Ƌ: "Paso de Despeñaperros / Province de Jaen, 3.IV.72 / Paratype / Pseudomedon (Euphonus) lecoqi H. Coiffait 1979 / Muséum Paris 1985, Coll. H. Coiffait / Pseudomedon lecoqi Coiffait det. V. Assing 2009" (MNHNP).
 C o m m e n t: Pseudomedon lecoqi was described from a male holotype (deposited in the collection of J. C. Lecoq) and three paratypes collected at "Paso de Despeñaperros, Sierra Morena, IV-69" (COIFFAIT 1980). According to the original description (COIFFAIT 1980) and the key in COIFFAIT (1984), P. lecoqi is distinguished from P. pallidus only by the much larger eyes ("yeux nettement plus grands") and the slightly shorter antennae. A comparison of the male paratype of P. lecoqi deposited in the Coiffait collection at the MNHNP and the lectotype of P. pallidus revealed that indeed the eyes of P. lecoqi are slightly larger (approximately as large as in P. dido) and the elytra are shorter (again similar to those of P. dido), but no difference in antennal length was observed. Since the male of P. pallidus is unknown, it is not certain if the types of P. pallidus and P. lecoqi represent different species. Eye size and elytral length are subject to considerable intraspecific variation also in other Pseudomedon species (P. obscurellus, P. huetheri) (ASSING 2008b).
 D i a g n o s i s: Externally similar to the brachypterous morph of P. obscurellus and practically indistinguishable from P. dido. Habitus as in Fig. 15. Body length: 3.6 mm. Coloration of whole body pale yellowish-brown, with the abdomen slightly darker.
 Head not distinctly dilated behind eyes (Fig. 16). Eyes larger than antennomere I in cross-section (Fig. 17), approximately half as long as postocular region in dorsal view. Antenna slender, similar to that of P. dido. Elytra short, 0.85 times as long as pronotum.
 Ƌ: posterior margin of sternite VIII with shallow, broadly V-shaped posterior excision (distinctly less deep than in P. dido); aedeagus as in Fig. 5.
 C o m p a r a t i v e n o t e s: This species is reliably separated from the similar P. dido only by the less deep posterior excision of the male sternite VIII and the different shape of the aedeagus, from the brachypterous morph of P. obscurellus also by the longer antennae, and from P. pallidus by the larger eyes and the longer elytra.
 D i s t r i b u t i o n: Like the preceding species, P. lecoqi is apparently extremely rare. To my knowledge, it has become known only from the type locality in southern Spain (Map 2).

description: We have applied two different automatic classifier algorithms to the BATSE Current GRB Catalog data and we obtain three different classes of GRBs. Our results confirm the existence of a third, intermediate class of GRBs, with mean duration \sim 25-50 s, as deduced from a cluster analysis and from a neural network algorithm. Our analyses imply longer durations than those found by Mukherjee et al. (1998) and Horvath (1998), whose intermediate class had durations \sim 2-10 s. From the neural network analysis no difference in hardness between the two longest classes is found, and from both methods we find that the intermediate-duration class constitutes the most homogeneous sample of GRBs in its space distribution while the longest-duration class constitutes the most inhomogeneous one with \sim 0.1, being thus the deepest population of GRBs with z_max \sim 10. The trend previously found in long bursts, of spatial inhomogeneity increasing with hardness, only holds for this new longest-duration class.

description: Cultural heritage is a valuable asset for any country, and it is crucial to protect, restore, and preserve it because it is threatened by both nature and human actions. Preservation methods have always been a significant concern, and traditional methods of documentation, such as 2D drawings, pictures, and conventional 3D modelling systems, have proven to be inefficient in terms of cost, time, effort, and quality. However, with advancements in technology and digital transformation, more effective techniques have been developed. One such technique is photogrammetry, which has proven to be a convenient way to digitize cultural heritage. For countries such as Sudan, where rich inheritance is in inevitable danger of ongoing armed conflicts, it is important to preserve this cultural heritage. This paper studies the feasibility of using photogrammetry as a digitalization technique to preserve Sudan’s cultural heritage by reviewing previous experiences and conducting two case studies that investigate the applicability of the technique to non-experts, along with its potential and limitations. Selected objects were digitized using close-range photogrammetry with a low budget and simple equipment. The final outcome was promising, particularly for small and medium-sized objects. Finally, a list of recommendations is provided to facilitate the digitalization of Sudanese cultural heritage to preserve it.

description: Within the finite-field Kohn-Sham framework, static electric response properties of diatomic molecules are presented. The electronic energy, dipole moment ({\boldmath$μ$}), static dipole polarizability ({\boldmath$α$}) and first-hyperpolarizability ({\boldmath$β$}) are calculated through a pseudopotential-DFT implementation in Cartesian coordinate grid, developed in our laboratory earlier. We engage the Labello-Ferreira-Kurtz (LFK) basis set; while four local and non-local exchange-correlation (LDA, BLYP, PBE and LBVWN) functionals have been adopted. A detailed analysis of \emph{grid convergence} and its impact on obtained results, is presented. In each case the \emph{electric field optimization} was carefully monitored through a recently prescribed technique. For all three molecules (HCl, HBr, HI) considered, the agreement of all these quantities with widely successful and popular atom-centered-grid procedure, is excellent. To assess the efficacy and feasibility, companion calculations are performed for these on a representative molecule (HCl) at distorted geometries, far from equilibrium. Wherever possible, relevant comparison is made with available \emph{all-electron} data and experimental results. This demonstrates that Cartesian grid provides accurate, reliable results for such properties of many-electron systems within pseudopotential representation.

description: We developed a measurement system that enables the reconstruction of γ-ray time spectra in cascade decay schemes. As this system records all the time and energy information of γ-rays, reconstruction is possible after the measurement. Therefore, the energy regions for the γ-ray identification can be optimized in complicated cascade decay schemes. Moreover, in this system we can record data with time-dependent parameters of external perturbations, such as applied magnetic fields, and consequently we can investigate the correlations and responses of γ-rays to the perturbation. This property fulfills the demands required for quantum information research with γ-rays.

description: 3C58 is a young Crab-like supernova remnant. Historical evidence strongly suggests an association of the remnant with supernova SN 1181, which would make 3C58 younger than the Crab Nebula. Recent Chandra observations have identified the young 65 ms pulsar J0205+6449 at its center, embedded in a compact nebula which, we show here, appears to be confined by the pulsar wind termination shock. We present new Chandra observations of this compact nebula and embedded pulsar which set strong upper limits on thermal emission originating from the neutron star surface. These limits fall far below predictions of standard neutron star cooling, requiring the presence of exotic cooling processes in the neutron star core.

description: We provide a simple proof of the topological invariance of the Turaev-Viro model (corresponding to simplicial 3d pure Euclidean gravity with cosmological constant) by means of a novel diagrammatic formulation of the state sum models for quantum BF-theories. Moreover, we prove the invariance under more general conditions allowing the state sum to be defined on arbitrary cellular decompositions of the underlying manifold. Invariance is governed by a set of identities corresponding to local gluing and rearrangement of cells in the complex. Due to the fully algebraic nature of these identities our results extend to a vast class of quantum groups. The techniques introduced here could be relevant for investigating the scaling properties of non-topological state sums, being proposed as models of quantum gravity in 4d, under refinement of the cellular decomposition.

description: We have re-analyzed using a hydrodynamic model large flaring events on three different categories of pre-main sequence (PMS) stars: the young stellar object (YSO) YLW 15, the classical T Tauri star (CTTS) LkHalpha92, the weak-line T Tauri star (WTTS) V773 Tau, and the WTTS HD 283572 (the first three objects were observed by ASCA, the last by ROSAT; all have been previously reported in the literature). The first three flares were previously analyzed on the basis of the quasi-static model mostly used up to now, consistently yielding large loops (L >= R*) and no evidence of sustained heating. Our hydrodynamic modeling approach, however, shows that the size of the flaring regions must be much smaller (L <=R*) and moreover this method shows in all cases evidence of vigorous sustained heating during the flare decay, so that the decay of the observed light curve actually reflects the temporal profile of the heating rather than that of the free decay of the heated loop(s). The events on the protostar YLW 15 have durations comparable to the stellar rotation period, so that their limited size and their lack of self-eclipses give evidence of a polar location on the star. This is in contrast with the recently advanced hypothesis that these flares are due to long loops spanning the region between the star and the accretion disk. In general, the present analysis shows that flaring coronae on PMS stars have a structure similar to the coronae on older active stars.

description: Critical parameters in three screened potentials, namely, Hulthén, Yukawa and exponential cosine screened Coulomb potential are reported. Accurate estimates of these parameters are given for each of these potentials, for all states having $n \leq 10$. Comparison with literature results is made, wherever possible. Present values compare excellently with reference values; for higher $n,\ell$, our results are slightly better. Some of these are presented for first time. Further, we investigate the spherical confinement of H atom embedded in a dense plasma modeled by an exponential cosine screened potential. Accurate energies along with their variation with respect to box size and screening parameter are calculated and compared with reference results in literature. Sample dipole polarizabilities are also provided in this case. The generalized pseudospectral method is used for accurate determination of eigenvalues and eigenfunctions for all calculations.

description: Cultural heritage of a nation forms its identity, inherited from past generations and to be passed to the next. Therefore, it is crucial to preserve it from natural and human effects or even worse, extinction. Throughout time, several approaches were utilized to preserve the cultural heritage from text, drawing, photographs to the modern-day digitized 3D models, points clouds with coordinates, achieving a higher accuracy and more realistic results. This paper focuses on the digitization of cultural heritage using close range terrestrial photogrammetry. The study was conducted on a self-financed low budget, simple equipment and non-professional group of researchers. Al Bidya Mosque, the oldest mosque in the United Arab Emirates, was taken as a focal point of the study, reflecting the country’s cultural and religious heritage built in the 15th Century. The main objective of this study is to investigate how cultural heritage sites can be documented and preserved using close range photogrammetry while exploring the potentials and challenges of close-range photogrammetry.
The redshift and scale dependence of the cosmic shear signal from numerical simulations

Subjects: subject: Astrophysics (astro-ph)

description: The weak lensing shear signal has been measured numerically in $N$-body simulations at 14 different redshifts ($z_s = 0.1$ to 3.6) and on angular scales of $θ= 2'$ to 32'. In addition, the data have been validated by analytical computations for an identical cosmology, with density parameter $Ω_m = 0.3$ and vacuum energy density parameter $λ_0 = 0.7$. This paper reports on the scale and redshift dependence of the shear variance, $$, which may be described by a simple formula of the form $(θ,z_s) = a(θ)z_s^{b(θ)}$. The redshift dependence for source redshifts up to 1.6, is found to be close to $z_s^2$, which is a stronger dependence than earlier analytical predictions ($ \propto z_s^{1.52}$), although, at higher redshifts, the $z_s$ dependence of the shear variance is clearly less steep. The strong redshift dependence further emphasises the need to know the precise redshift distribution for the galaxy sources in any given survey, so that they can be allocated to redshift bins accordingly, and the cosmic shear signal correctly interpreted. Equations are also given for the variance in the reduced shear, which is a more directly measurable quantity observationally.

Higher Order Variability Properties of Accreting Black Holes

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

description: To better constrain the emission mechanism underlying the hard state of galactic black hole candidates, we use high-time resolution RXTE lightcurves for Cyg X-1 and GX 399-4 to compute two higher order variability statistics for these objects, the skewness and the Fourier bispectrum. Similar analyses, in particular using the skewness measure, have been attempted before, but the photon collection area of RXTE allows us to present results of much greater statistical significance. The results for the two objects are qualitatively similar, reinforcing the idea that the same basic mechanisms are at work in both. We find a significantly positive skewness for variability timescales less than $\sim 1 $ second, and a {\it negative} skewness for timescale $1- 5 $ sec. Such a skewness pattern cannot be reproduced by the simplest shot variability models where individual shots have a fixed profile and intensity and are uncorrelated in time. Further evidence against simple shot models comes from the significant detection of a non-zero bicoherence for Fourier periods $\sim 0.1-10$ sec, implying that significant coupling does exist between variations on these timescales. We discuss how current popular models for variability in black hole systems can be modified to match these observations. Using simulated light curves, we suggest that the most likely way to reproduce this observed behavior is to have the variability come in groups of many shots, with the number of shots per unit time fitting an envelope function which has a rapid rise and slow decay, while the individual shots have a slow rise and a rapid decay. Invoking a finite energy reservoir that is depleted by each shot is a natural way of producing the required shot correlations.

description: Magnon spintronics is a prosperous field that promises beyond-CMOS technology based on elementary excitations of the magnetic order that act as information carriers for future computational architectures. Unidirectional propagation of spin waves is key to the realization of magnonic logic devices. However, previous efforts to enhance the Damon-Eshbach-type nonreciprocity did not realize (let alone control) purely unidirectional propagation. Here we experimentally demonstrate excitations of unidirectional exchange spin waves by a nanoscale magnetic grating consisting of Co nanowires fabricated on an ultrathin yttrium iron garnet film. We explain and model the nearly perfect unidirectional excitation by the chirality of the magneto-dipolar interactions between the Kittel mode of the nanowires and the exchange spin waves of the film. Reversal of the magnetic configurations of film and nanowire array from parallel to antiparallel changes the direction of the excited spin waves. Our results raise the prospect of a chiral magnonic logic without the need for fragile surface states.

An economic analysis of the performance of the agricultural cooperative system in Thailand
Creators: name: Somrongwatana, Suwannee
Publisher: name: Canberra, ACT : The Australian National University
Year: 1978
Subjects: subject: Agriculture, Cooperative Thailand

description: The multi-purpose agricultural cooperatives of Thailand play an increasingly important part in the economic life of the country. They are an instrument of Thai government policy, intended both to help modernize farming and to perform welfare functions, especially in relieving farmers from debt. They are expected to carry out a number of purposes, i.e., credit, selling farm supplies, purchasing crops etc. The data available were mainly aggregates, so that the study is essentially a macro study. But it is combined with attempts to probe the situation also at the micro level. Thus, the study was primarily concerned with analysing data from the agricultural cooperatives in the aggregate but also presents a case study of 3 individual societies. The whole study was based on time series analysis and cross sectional analysis. The study stresses the inadequacy of management of the cooperatives in decision-making, financial skills, attracting business to the societies and in maintaining the loyalty of their members. It also shows that the aims of the. government are not being effectively realized. Some assistance is being given through the cooperative system to the modernization of agriculture, but this seems to be only limited. The movements' welfare aims, however, are hardly being carried out. The farmers that benefit from subsidised state assistance channelled through the cooperative system are the middle income class. The poorer farmers so far seem to be missing out on the benefits. Overall, less than 10 percent of all farmers are members of societies. On the financial aspects of the societies, the accountancy system was found to be inadequate. The accounts are not presented in a conventional way and fail to make adequate provision for doubtful debts, depreciation and stock changes. They also lack a flow of funds statement which would help make the financial position clearer now that the societies are undertaking multi-purpose activities. The concluding chapter of the thesis gives some recommendations for remedial action. More specifically, it makes three main recommendations. First, that the efficiency of primary level cooperative management should be improved through incentive payments and greater training, especially in financial skills. Second, that the societies should be granted greater flexibility to respond to market conditions, in offering higher prices or in paying higher interest rates, so as to attract more membership and greater loyalty from their members. Lastly, that much more extensive research should be carried out on agricultural cooperatives in Thailand.

description: The recent development of Large Language Models (LLMs) in the last two years has enhanced the potential of creating facilitation chatbots that enhance creativity and productivity in the online community. However, the impact of facilitation chatbots on learning confidence is yet to be clearly articulated. In this study, we introduce facilitation agents that implement understanding and content-generation capabilities on learning platforms with the participation of undergraduate students. It explores the potential of LLMs to enrich pre- and post-lecture discussions by providing diverse viewpoints and stimulating engagement with lecture contents among participants. In this paper, we investigated the effect of facilitation chatbots on students' learning confidence during synchronous e-learning courses. In the control experimental study (n=80), we found that chatbots induced learning confidence most effectively, making students experience strong confidence in the learning platform, likely due to the chatbot's contextual knowledge and human touch. Our study provides insight into creating effective chatbots to enhance students' confidence, skills, benefits, and involvement in the pre- and post-learning processes.

description: To realize topological superconductor is one of the most attracting topics because of its great potential in quantum computation. In this study, we successfully intercalate potassium (K) into the van der Waals gap of type II Weyl semimetal WTe2, and discover the superconducting state in KxWTe2 through both electrical transport and scanning tunneling spectroscopy measurements. The superconductivity exhibits an evident anisotropic behavior. Moreover, we also uncover the coexistence of superconductivity and the positive magneto-resistance state. Structural analysis substantiates the negligible lattice expansion induced by the intercalation, therefore suggesting K-intercalated WTe2 still hosts the topological nontrivial state. These results indicate that the K-intercalated WTe2 may be a promising candidate to explore the topological superconductor.

description: One method of studying the asymptotic structure of spacetime is to apply Penrose's conformal rescaling technique. In this setting, the Einstein equations for the metric and the conformal factor in the unphysical spacetime degenerate where the conformal factor vanishes, namely at the boundary representing null infinity. This problem can be avoided by means of a technique of H. Friedrich, which replaces the Einstein equations in the unphysical spacetime by an equivalent system of equations which is regular at the boundary. The initial value problem for these equations produces a system of constraint equations known as the conformal constraint equations. This work describes some of the properties of the conformal constraint equations and develops a perturbative method of generating solutions near flat space under certain simplifying assumptions.
description: 22 pages. Will appear in the proceedings of the internationl workshop on the conformal structure of spacetime (Tuebingen, Germany, April 2001). This is the final version and is significantly different from Version 1

description: Pulsational properties of 1.8 M$_{\odot}$ stellar models covering the latest stages of contraction toward the main sequence up to early hydrogen burning phases are investigated by means of linear nonadiabatic analyses. Results confirm that pre-main sequence stars (pms) which cross the classical instability strip on their way toward the main sequence are pulsationally unstable with respect to the classical opacity mechanisms. For both pms and main sequence types of models in the lower part of the instability strip, the unstable frequency range is found to be roughly the same. Some non-radial unstable modes are very sensitive to the deep internal structure of the star. It is shown that discrimination between pms and main sequence stages is possible using differences in their oscillation frequency distributions in the low frequency range.

description: Static electric response properties of atoms and molecules are reported within the real-space Cartesian grid implementation of pseudopotential Kohn-Sham (KS) density functional theory (DFT). A detailed systematic investigation is made for a representative set of atoms and molecules, through a number of properties like total ground-state electronic energies, permanent dipole moment ($\bmμ$), static average dipole polarizability ($\overlineα$). This is further extended to first-hyperpolarizability ($\bmβ$) in molecules. It employs a recently developed non-uniform grid-optimization technique, with a suitably chosen fixed initial applied field. A simple variant of the finite-field method, using a rational function fit to the dipole moment with respect to electric field, is adopted. We make use of Labello-Ferreira-Kurtz (LFK) basis set, which has performed quite well in these scenarios. To assess the efficacy and feasibility, four XC functionals such as LDA, BLYP, PBE and LBVWN are chosen. Present results are compared with available literature (both theoretical and experimental) values, whenever possible. In all instances, they show excellent agreement with the respective atom-centered-grid results, very widely used in many quantum chemistry programs. This demonstrates a viable alternative towards accurate prediction of response properties of many-electron systems in Cartesian coordinate grid.

description: The pyrochlore material Nd$_2$Zr$_2$O$_7$ with an "all-in-all-out" (AIAO) magnetic order shows novel quantum moment fragmentation with gapped flat dynamical spin ice modes. The parameterized spin Hamiltonian with a dominant frustrated ferromagnetic transverse term reveals a proximity to a U(1) spin liquid. Here we study magnetic excitations of Nd$_2$Zr$_2$O$_7$ above the ordering temperature ($T_\text{N}$) using high-energy-resolution inelastic neutron scattering. We find strong spin ice correlations at zero energy with the disappearance of gapped magnon excitations of the AIAO order. It seems that the gap to the dynamical spin ice closes above $T_\text{N}$ and the system enters a quantum spin ice state competing with and suppressing the AIAO order. Classical Monte Carlo, molecular dynamics and quantum boson calculations support the existence of a Coulombic phase above $T_\text{N}$. Our findings relate the magnetic ordering of Nd$_2$Zr$_2$O$_7$ with the Higgs mechanism and provide explanations for several previously reported experimental features.
