description: Omics fusion has emerged as a crucial preprocessing approach in the field of medical image processing, providing significant assistance to several studies. One of the challenges encountered in the integration of omics data is the presence of unpredictability arising from disparities in data sources and medical imaging equipment. In order to overcome this challenge and facilitate the integration of their joint application to specific medical objectives, this study aims to develop a fusion methodology that mitigates the disparities inherent in omics data. The utilization of the multi-kernel late-fusion method has gained significant popularity as an effective strategy for addressing this particular challenge. An efficient representation of the data may be achieved by utilizing a suitable single-kernel function to map the inherent features and afterward merging them in a space with a high number of dimensions. This approach effectively addresses the differences noted before. The inflexibility of label fitting poses a constraint on the use of multi-kernel late-fusion methods in complex nasopharyngeal carcinoma (NPC) datasets, hence affecting the efficacy of general classifiers in dealing with high-dimensional characteristics. This innovative methodology aims to increase the disparity between the two cohorts, hence providing a more flexible structure for the allocation of labels. The examination of the NPC-ContraParotid dataset demonstrates the model's robustness and efficacy, indicating its potential as a valuable tool for predicting distant metastases in patients with nasopharyngeal carcinoma (NPC).

description: Knowledge representation and reasoning are critical challenges in Artificial Intelligence (AI), particularly in integrating neural and symbolic approaches to achieve explainable and transparent AI systems. Traditional knowledge representation methods often fall short of capturing complex processes and state changes. We introduce Neuro-Conceptual Artificial Intelligence (NCAI), a specialization of the neuro-symbolic AI approach that integrates conceptual modeling using Object-Process Methodology (OPM) ISO 19450:2024 with deep learning to enhance question-answering (QA) quality. By converting natural language text into OPM models using in-context learning, NCAI leverages the expressive power of OPM to represent complex OPM elements-processes, objects, and states-beyond what traditional triplet-based knowledge graphs can easily capture. This rich structured knowledge representation improves reasoning transparency and answer accuracy in an OPM-QA system. We further propose transparency evaluation metrics to quantitatively measure how faithfully the predicted reasoning aligns with OPM-based conceptual logic. Our experiments demonstrate that NCAI outperforms traditional methods, highlighting its potential for advancing neuro-symbolic AI by providing rich knowledge representations, measurable transparency, and improved reasoning.

description: In this fourth paper of the series, we use the parametrized, spherically symmetric explosion method PUSH to perform a systematic study of two sets of non-rotating stellar progenitor models. Our study includes pre-explosion models with metallicities Z=0 and Z=Z$_{\odot}\times 10^{-4}$ and covers a progenitor mass range from 11 up to 75 M$_\odot$. We present and discuss the explosion properties of all models and predict remnant (neutron star or black hole) mass distributions within this approach. We also perform systematic nucleosynthesis studies and predict detailed isotopic yields as function of the progenitor mass and metallicity. We present a comparison of our nucleosynthesis results with observationally derived $^{56}$Ni ejecta from normal core-collapse supernovae and with iron-group abundances for metal-poor star HD~84937. Overall, our results for explosion energies, remnant mass distribution, $^{56}$Ni mass, and iron group yields are consistent with observations of normal CCSNe. We find that stellar progenitors at low and zero metallicity are more prone to BH formation than those at solar metallicity, which allows for the formation of BHs in the mass range observed by LIGO/VIRGO.

description: {A} Higher Spin Gravity in five dimensions is constructed. It was shown recently that constructing formally consistent classical equations of motion of higher spin gravities is equivalent to finding a certain deformation of a given higher spin algebra. A strong homotopy algebra encoding the interaction vertices then follows. We propose two different and novel realizations of the deformed higher spin algebra in the case of five dimensions: one in terms of the universal enveloping algebra of $su(2,2)$ and the other by means of oscillator variables. Both the new realizations admit supersymmetric extensions and the $\mathcal{N}=8$ case underlies the massless sector of tensionless strings.

Keck/OSIRIS IFU Detection of a z $\sim$ 3 Damped Lyman Alpha Host Galaxy

description: We present Keck/OSIRIS infrared IFU observations of the $z = $ 3.153 sub-DLA DLA2233+131, previously detected in absorption to a background quasar and studied with single slit spectroscopy and PMAS integral field spectroscopy (IFU). We used the Laser Guide Star Adaptive Optics (LGSAO) and OSIRIS IFU to reduce the point-spread function of the background quasar to FWHM$\sim$0.15 arcseconds and marginally resolve extended, foreground DLA emission. We detect [OIII]$λ$5007 emission with a flux F$^{[OIII]\lambda5007}$ = $(2.4\pm0.5)\times10^{-17}$ erg s$^{-1}$ cm$^{-2}$, as well as unresolved [OIII]$λ$4959 and H$βλ$4861 emission. Using a composite spectrum over the emission region, we measure dynamical mass $\sim$ $3.1\times10^9$ M$_{\odot}$. We make several estimates of star formation rate using [OIII]$λ$5007 and H$βλ$4861 emission, and measure a star formation rate of $\sim$ $7.1- 13.6$ M$_{\odot}$ yr$^{-1}$. We map [OIII]$λ$5007 and H$βλ$4861 emission and the corresponding velocity fields to search for signs of kinematic structure. These maps allow for a more detailed kinematic analysis than previously possible for this galaxy. While some regions show slightly red and blue-shifted emission indicative of potential edge-on disk rotation, the data are insufficient to support this interpretation.

El presente documento se refiere al proceso de traducción escénica de la Compañía de Teatro Los Niños del Cid, que consiste en la ejercitación, producción y realización de una puesta en escena transmedial entendido como un proceso artístico multidisciplinario, es decir que genera un cruce de disciplinas artísticas (teatro, artes visuales, música y tecnología), plasmando de esta manera características que posee el discurso en sí, vale decir la ausencia y la necesidad de recuperación del héroe en una época actual que definiremos y fundamentaremos como transmoderna, en otras palabras la estructuración de una maquinaria expresiva transmedial está en estrecha relación con el mundo contemporáneo en el que nos encontramos actualmente, la proliferación de los medios de comunicación y los estímulos que de éstos nace, y esta característica tomada del mundo contemporáneo es cruzada con una historia épica, generando una tensión dramática que hace validarla también en un mundo contemporáneo, es decir permitir que pueda existir en una sumatoria medios actuales, y no sólo eso, si no que la rescata, sumergiéndose en esa época e interpretándola mediante un tratamiento escénico que estructura diferentes medios expresivos, teniendo por principal, el medio escénico.

description: Very Long Baseline Atom Interferometry (VLBAI) corresponds to ground-based atomic matter-wave interferometry on large scales in space and time, letting the atomic wave functions interfere after free evolution times of several seconds or wave packet separation at the scale of meters. As inertial sensors, e.g., accelerometers, these devices take advantage of the quadratic scaling of the leading order phase shift with the free evolution time to enhance their sensitivity, giving rise to compelling experiments. With shot noise-limited instabilities better than $10^{-9}$ m/s$^2$ at 1 s at the horizon, VLBAI may compete with state-of-the-art superconducting gravimeters, while providing absolute instead of relative measurements. When operated with several atomic states, isotopes, or species simultaneously, tests of the universality of free fall at a level of parts in $10^{13}$ and beyond are in reach. Finally, the large spatial extent of the interferometer allows one to probe the limits of coherence at macroscopic scales as well as the interplay of quantum mechanics and gravity. We report on the status of the VLBAI facility, its key features, and future prospects in fundamental science.

Study of Counting Characteristics of Porous Radiation Detectors

description: This paper presents the development of a new technology of registration of ionizing radiation and a new type of detectors - single-cathode multiwire porous detector with neither a gaseous nor semiconductor, but a porous dielectric substance, e.g., CsI, being used as working medium. It is shown that the performance of the multiwire porous detector is stable, ensuring highly efficient detection of both heavily ionizing particles and soft X-rays with a spatial resolution better than $\pm 60μm$. The continuous stable performance opens up new perspectives for using porous detectors in research as well as medicine. The obtained data are basic for the development of the theory of the phenomenon of electrons' drift and multiplication in porous dielectrics under the action of a strong external electric field.

description: In rare-earth permanent magnets (REPM's), trade-off's between intrinsic magnetic properties are often encountered. A recent example is SmFe$_{12}$ where excellent magnetic properties can be achieved at the sacrifice of bulk structure stability. Bulk structure stability is sustained by the presence of the third substitute element as is the case with SmFe$_{11}$Ti, where Ti degrades magnetic properties. It is now in high demand to find out with which chemical composition a good compromise in the trade-off between structure stability and strong ferromagnetism is reached. We inspect the effects of representative substitute elements, Zr, Ti, and Co in SmFe$_{12}$ by combining ab initio data with experimental data from neutron diffraction. The trend in the intrinsic properties with respect to the concentration of substitute elements are monitored and a systematic way to search the best compromise is constructed. A certain minimum amount of Ti is identified with respect to the added amount of Co and Zr. It is found that Zr brings about a positive effect on magnetization, in line with recent experimental developments, and we argue that this can be understood as an effective doping of extra electrons.

description: Degeneracy (exceptional) points embedded in energy band are distinct by their topological features. We report different hybrid two-state coalescences (EP2s) formed through merging two EP2s with opposite chiralities that created from the type III Dirac points emerging from a flat band. The band touching hybrid EP2, which is isolated, is induced by the destructive interference at the proper match between non-Hermiticity and synthetic magnetic flux. The degeneracy points and different types of exceptional points are distinguishable by their topological features of global geometric phase associated with the scaling exponent of phase rigidity. Our findings not only pave the way of merging EPs but also shed light on the future investigations of non-Hermitian topological phases.

description: The aim of this study was to develop an effective sample preparation method for the extraction and trace determination of chlorpyrifos pesticide. The method was a combination of dispersive solid-phase extraction (DSPE) and dispersive liquid–liquid microextraction (DLLME) coupled with high-performance liquid chromatography (HPLC). Different factors affecting the performance of the extraction steps in both methods were thoroughly investigated and optimised. They included type and volume of the extractor and disperser solvents in DLLME extraction, as well as type and volume of the elution solvent, type and amount of sorbent in DSPE extraction. The salt addition, pH of solution, and also centrifuging time and speed were taken into account. Under optimal conditions, the enrichment factors were between 177 and 293, and the extraction recoveries were 91–98%. The linear range was 5–400 µg L−1, and limits of detection (LOD) were between 0.9 and 1.8 µg L−1. The relative standard deviations (RSDs) for 100 µg L−1 of chlorpyrifos in urine were in the range of 1.9–3.7% (n = 6). The relative recoveries of the pesticide from urine samples spiked with levels of 10, 100 and 300 µg L-1 were obtained 95.1–101.3%. Compared to other extraction techniques, DSPE–DLLME-HPLC method enjoys some advantages such as the shorter extraction time, high extraction efficiency, and good enrichment factor for the extraction of chlorpyrifos from human urine samples. In addition, it is simple, inexpensive, and highly sensitive, and it can be successfully applied to separation, pre-concentration, and determination of the pesticides in different aqueous samples.

description: In the wake of current moves to dismantle apartheid in South Africa, the agricultural sector is seeking ways of restructuring its dualistic nature. Restructuring may affect both equity and productivity. Hungarian and other experiences can provide useful guidelines. Hungary's restructuring has virtually come full circle from individual units to colelctivization to individualization. Individual units have performed better than collective units. In its restructuring, South Africa must avoid the mistakes of others, striking a balance between equity and productivity.

description: The 15O(alpha,gamma)19Ne reaction is one of two routes for breakout from the hot CNO cycles into the rp process in accreting neutron stars. Its astrophysical rate depends critically on the decay properties of excited states in 19Ne lying just above the 15O + alpha threshold. We have measured the alpha-decay branching ratios for these states using the p(21Ne,t)19Ne reaction at 43 MeV/u. Combining our measurements with previous determinations of the radiative widths of these states, we conclude that no significant breakout from the hot CNO cycle into the rp process in novae is possible via 15O(alpha,gamma)19Ne, assuming current models accurately represent their temperature and density conditions.

description: The popularly accepted rice production system in Taiwan is contract cultivation. This paper investigates the production efficiency of rice farming under the contract cultivation system. Data obtained from the financial accounts of 60 rice-farming families are used and estimated in a translog cost function. The efficiency indicators are the elasticities of input demand combinations with respsect to own and cross-input prices and the average incremental cost. The results show that contract labour demand is the msot rigid input for the adjustment of rice production efficiency. The low elasticities of input substitution and of per-unit output variable cost further prove the limitied ability of rice farmers to improve efficiency except via deregulation and land policy. Some policy implications are also presented.

description: We uncover a topological classification applicable to open fermionic systems governed by a general class of Lindblad master equations. These `quadratic Lindbladians' can be captured by a non-Hermitian single-particle matrix which describes internal dynamics as well as system-environment coupling. We show that this matrix must belong to one of ten non-Hermitian Bernard-LeClair symmetry classes which reduce to the Altland-Zirnbauer classes in the closed limit. The Lindblad spectrum admits a topological classification, which we show results in gapless edge excitations with finite lifetimes. Unlike previous studies of purely Hamiltonian or purely dissipative evolution, these topological edge modes are unconnected to the form of the steady state. We provide one-dimensional examples where the addition of dissipators can either preserve or destroy the closed classification of a model, highlighting the sensitivity of topological properties to details of the system-environment coupling.

The Covariant Entropy Bound, Brane Cosmology, and the Null Energy Condition

description: In discussions of Bousso's Covariant Entropy Bound, the Null Energy Condition is always assumed, as a sufficient {\em but not necessary} condition which helps to ensure that the entropy on any lightsheet shall necessarily be finite. The spectacular failure of the Strong Energy Condition in cosmology has, however, led many astrophysicists and cosmologists to consider models of dark energy which violate {\em all} of the energy conditions, and indeed the current data do not completely rule out such models. The NEC also has a questionable status in brane cosmology: it is probably necessary to violate the NEC in the bulk in order to obtain a "self-tuning" theory of the cosmological constant. In order to investigate these proposals, we modify the Karch-Randall model by introducing NEC-violating matter into $AdS_5$ in such a way that the brane cosmological constant relaxes to zero. The entropy on lightsheets remains finite. However, we still find that the spacetime is fundamentally incompatible with the Covariant Entropy Bound machinery, in the sense that it fails the Bousso-Randall consistency condition. We argue that holography probably forbids all {\em cosmological} violations of the NEC, and that holography is in fact the fundamental physical principle underlying the cosmological version of the NEC.

description: Logging contractor profits have been reported to decrease substantially in Swedish forestry in later years. During the same period there have been reports on a declining work environment in logging leading to difficult recruitment of personnel. Previous research has shown needs for both business and work environment development in the logging industry. This article continues our efforts at describing and analyzing the strategic choices logging contractors make in order to develop or transform their companies to improve profitability and work environment. We have interviewed logging contractors and other representatives of the logging industry regarding contractor incentives for investing in and developing new products and services as well as existing business activities. We have explored the same themes in seminars contractors, employed machine operators, and buyers of logging services. The contractor strategies we identify are about creating and appropriating value by utilizing the resources of the firm and market possibilities.

description: The impact of an ad valorem export tax on Pakistan's Basmati rice trade is analysed in a partial equilibrium framework. Results suggest that producers of Basmati rice lost a considerable amount of their producer surplus while consumers gained in terms of their consumer surplus. The national treasury received tax revenues as well as some positive increases in foreign exchange earnings. The nation as a whole thus gained. However, the tax pushes up international prices, which may encourage other producers to increase their production and compete for their shares. A gradual decrease in the level of the export tax and an increase in producer price may take care of the adverse effects of the export tax.

description: A novel THz near-field spectrometer is presented which allows to perform biological and medical studies with high spectral resolution combined with a spatial resolution down to l/100. In the setup an aperture much smaller than the used wavelength is placed in the beam very close to the sample. The sample is probed by the evanescent wave behind the aperture. The distance is measured extremely accurate by a confocal microscope. We use monochromatic sources which provide powerful coherent cw radiation tuneable from 50 GHz up to 1.5 THz. Transmission and reflection experiments can be performed which enable us to study solids and molecules in aqueous solution. Examples for spectroscopic investigations on biological tissues are presented.

Analyzing Gravastar Structure with the Finch-Skea Metric in Extended Modified Symmetric Teleparallel Gravity

description: This study analyzes the physical features of a gravastar within the $f(\mathcal{Q}, \mathbb{T})$ gravity framework, where $\mathcal{Q}$ is the non-metricity scalar and $\mathbb{T}$ is the trace of the energy-momentum tensor. Gravastars present a viable alternative to black holes, featuring a central de Sitter core, a surrounding thin shell and a dynamic layer in the Schwarzschild exterior that separates these two regions. Using the Finch-Skea metric, the necessary field equations for the core and shell are derived, while the Israel junction conditions maintain a seamless connection between the inner and outer regions. This work extensively explores crucial aspects such as energy distribution, proper length, energy conditions, entropy and the equation of state parameter. The model's stability is studied through the effective potential, redshift, causality conditions and adiabatic index. Our results highlight the essential role of modified gravity in maintaining the structural viability and stability of gravastars.

Specific Heat Discontinuity in Impure Two-Band Superconductors

description: The Ginzburg-Landau coefficients, and the jump of the specific heat are calculated for a disordered two-band superconductor. We start with the analysis of a more general case arbitrary anisotropy. While the specific heat discontinuity at the critical temperature T_c decreases with increasing disorder, its ratio to the normal state specific heat at T_c increases and slowly converges to the isotropic value. For a strong disorder the deviation from the isotropic value is proportional to the elastic electron scattering time. In the case of a two-band superconductor we apply a simplified model of the interaction independent on momentum within a band. In the framework of this model all thermodynamic values can be found explicitly at any value of the scattering rate. This solution explains the sample dependence of the specific heat discontinuity in MgB_2 and the influence of the disorder on the critical temperature.

description: We develop an unsupervised machine learning algorithm for the automated discovery and identification of traveling waves in spatio-temporal systems governed by partial differential equations (PDEs). Our method uses sparse regression and subspace clustering to robustly identify translational invariances that can be leveraged to build improved reduced order models (ROMs). Invariances, whether translational or rotational, are well known to compromise the ability of ROMs to produce accurate and/or low-rank representations of the spatio-temporal dynamics. However, by discovering translations in a principled way, data can be shifted into a coordinate systems where quality, low-dimensional ROMs can be constructed. This approach can be used on either numerical or experimental data with or without knowledge of the governing equations. We demonstrate our method on a variety of PDEs of increasing difficulty, taken from the field of fluid dynamics, showing the efficacy and robustness of the proposed approach.

description: We studied the $^{12}$C(p,2p+n) reaction at beam momenta of 5.9, 8.0 and 9.0 GeV/c. For quasielastic (p,2p) events we reconstructed {\bf p_f} the momentum of the knocked-out proton before the reaction; {\bf p_f} was then compared (event-by-event) with {\bf p_n}, the measured, coincident neutron momentum. For $|p_n|$ > k$_F$ = 0.220 GeV/c (the Fermi momentum) a strong back-to-back directional correlation between {\bf p_f} and {\bf p_n} was observed, indicative of short-range n-p correlations. From {\bf p_n} and {\bf p_f} we constructed the distributions of c.m. and relative motion in the longitudinal direction for correlated pairs. After correcting for detection efficiency, flux attenuation and solid angle, we determined that 49 $\pm$ 13 % of events with $|p_f|$ > k_F had directionally correlated neutrons with $|p_n|$ > k$_F$. Thus short-range 2N correlations are a major source of high-momentum nucleons in nuclei.

description: This paper examines the consistency of two series of aggregate output data in comparing the agricultural performance of60 developing countries. Employing two approaches that take into account the fact that deepening of intermediate goods takes place in agriculture as development proceeds, it is found that, in less than half the country cases tested, the data on gross agricultural output compiled by the US Department of Agriculture and the series on value-added in agriculture .produced by the World Bank are consistent with each other and with the expectation of deepening of intermediate goods. The World Bank's aggregates provide the more optimistic reading of performance of the two series, but neither series indicates that a majority of developing countries have performed adequately in terms of the test of agricultural performance suggested by Johnston and Mellor in 1961.
