Multi-modal Machine Translation (MMT) enables the use of visual information to enhance the quality of translations. The visual information can serve as a valuable piece of context information to decrease the ambiguity of input sentences. Despite the increasing popularity of such a technique, good and sizeable datasets are scarce, limiting the full extent of their potential. Hausa, a Chadic language, is a member of the Afro-Asiatic language family. It is estimated that about 100 to 150 million people speak the language, with more than 80 million indigenous speakers. This is more than any of the other Chadic languages. Despite a large number of speakers, the Hausa language is considered low-resource in natural language processing (NLP). This is due to the absence of sufficient resources to implement most NLP tasks. While some datasets exist, they are either scarce, machine-generated, or in the religious domain. Therefore, there is a need to create training and evaluation data for implementing machine learning tasks and bridging the research gap in the language. This work presents the Hausa Visual Genome (HaVG), a dataset that contains the description of an image or a section within the image in Hausa and its equivalent in English. To prepare the dataset, we started by translating the English description of the images in the Hindi Visual Genome (HVG) into Hausa automatically. Afterward, the synthetic Hausa data was carefully post-edited considering the respective images. The dataset comprises 32,923 images and their descriptions that are divided into training, development, test, and challenge test set. The Hausa Visual Genome is the first dataset of its kind and can be used for Hausa-English machine translation, multi-modal research, and image description, among various other natural language processing and generation tasks. © European Language Resources Association (ELRA), licensed under CC-BY-NC-4.0.

Unextendible product bases (UPBs) provide a versatile tool with various applications across different areas of quantum information theory. Their comprehensive characterization is thus of great importance and has been a subject of vital interest for over two decades now. An open question asks about the existence of UPBs, which are genuinely unextendible, i.e., they are not extendible even with biproduct vectors. In other words, the problem is to verify whether there exist genuinely entangled subspaces (GESs), subspaces composed solely of genuinely multiparty entangled states, complementary to UPBs. We solve this problem in the negative for many sizes of UPBs in different multipartite scenarios. In particular, in the all-important case of equal local dimensions, we show that there are always forbidden cardinalities for such UPBs, including the minimal ones corresponding to GESs of the maximal dimensions.

We present an analysis of the characteristics of a therapeutic photon beam simulated by the G4RT simulator which is based on the Monte Carlo method. Development of the G4RT is a part of the Dose-3D project. In order to verify the reliability of the implemented simulator, spatial dose distributions were compared with the real measurements and results from the PRIMO simulator. For the purpose of assessment, the primary photons analysis was performed. Results show the reliability of the G4RT. Therefore, the simulator can be used in further research. © 2022 Jagellonian university. All rights reserved.

Multiparticle azimuthal cumulants from transverse momentum conservation and collective flow

arXiv 2022年

We calculate the nth order of 2k-particle azimuthal cumulants cn{2k} based on transverse momentum conservation (TMC) and collective flow vn(n=2,3). We demonstrate that the TMC effect only leads to a nonzero cn{2k} with the sign of (−1)nk and the magnitude inversely proportional to (N − 2k)nk. The interplay between TMC and collective flow can change the signs of c2{4}, c3{2} and c3{4} at some values of multiplicity N, which could provide a good probe to study the onset of collectivity and search for the substructure of proton in small colliding systems. © 2022, CC0.

The effect of the surface potential of biomaterials on cell attachment and development in regenerative medicine is still an unexplored area driving many regeneration processes, especially in piezoelectric bone tissue. Within this study, we electrospun poly(L-lactide) scaffolds constructed of fibers with either higher (⁓600 mV) or lower (⁓300 mV) surface potential, which is controlled by applied voltage polarity during their production. Interestingly, this way, the piezoelectric performance of PLLA fibers can be enhanced. The direct measurement of the PLLA fiber surface potential using Kelvin probe force microscopy (KPFM) showed a good correlation with the zeta potential analysis. The piezoelectricity of PLLA fibers was verified with piezoelectric force microscopy (PFM), indicating that it can be enhanced by applying the positive voltage polarity to the nozzle during electrospinning. Importantly, the cell adhesion assay showed a significant effect of the higher surface potential of PLLA fibers on osteoblasts behavior and creating a favorable bioelectric microenvironment. We observed enhanced initial adhesion of cells in the first 5 h with no additional effect of surface potential on proliferation, morphology, or collagen production. It was demonstrated that electrospun PLLA fibers with tunable surface potential and piezoelectricity are excellent for constructing bone tissue engineering scaffolds. © 2023, The Authors.

This research presents a novel electromagnetic-based sensor for inline measurement of unmilled rice paddy moisture content in the rice mill factory. The proposed sensor has been designed based on the modified planar dipole structure at the operating frequency of 440 MHz. The unmilled rice dielectric constant properties have been studied and applied for characterizing the moisture content. The unmilled rice moisture content sensor system then has been designed consisting of the proposed sensor, a microwave signal generator, a microwave signal detector, and a microcontroller. The moisture content sensor system has been implemented and used for measuring the unmilled rice paddy moisture content in a real rice mill factory in Udon Thani province, Thailand. When compared with the commercial rice moisture content tool based on a capacitance technique, the proposed rice moisture content sensor system gives almost same results, which only about 4% difference has been found.

We describe a method to estimate Rényi entanglement entropy of a spin system which is based on the replica trick and generative neural networks with explicit probability estimation. It can be extended to any spin system or lattice field theory. We demonstrate our method on a one-dimensional quantum Ising spin chain. As the generative model, we use a hierarchy of autoregressive networks, allowing us to simulate up to 32 spins. We calculate the second Rényi entropy and its derivative and cross-check our results with the numerical evaluation of entropy and results available in the literature.

This look at addresses the critical project of reaching dependable and precise proprioception in soft robots, it really is essential for his or her effective deployment in complicated environments. By integrating multi-tap resistive sensors in the robot's form, our technique lets in for the distinct sensing of nearby deformations at various factors throughout the robotics' frame, moving beyond traditional techniques that anticipate steady curvature. We beautify the decision of these deformations and couple the sensory facts with a strong finite detail technique (FEM) model. This included framework allows the correct estimation of the smooth robot's form and the significance of outside forces applied to it, attaining a mean relative inaccuracy of about 4%. Additionally, our technique proves its software program in tender manipulation structures, in which it achieves thirteen% relative mistakes in external force estimation inside diverse zero to five N. The approach gives a promising direction for enhancing robotic interactions in sensitive and dynamic responsibilities, providing massive enhancements in robotic proprioception without reliance on outdoor monitoring generation. © 2024 IEEE.

Electron and neutrino scattering off the deuteron in a relativistic framework

Physical Review C 2023年第2期107卷 024617-024617页

We build a relativistic model to perform calculations of exclusive, semiexclusive, and inclusive unpolarized cross sections and various polarization observables in electron and neutrino scattering experiments with deuteron targets. The strong interaction dynamics is defined by an explicit dynamical unitary representation of the Poincaré group, where representations of space translations and rotations in the interacting and noninteracting representations are the same. The Argonne V18 potential is used to construct a relativistic nucleon-nucleon interaction reproducing the experimental deuteron binding energy and nucleon-nucleon scattering observables. Our formalism does not include the pion production channel and neglects two-body contributions in the electromagnetic as well as in the weak nuclear current operator. We show that it is applicable to processes at kinematics, where the internal two-nucleon energy remains below the pion production threshold but the magnitude of the three-momentum transfer extends at least to several GeV.
