The current research concentrated on the Co-precipitation synthesis of g-C3N4 (CN), ZnO, ZnO/CN, and Co-doped ZnO/CN nanocomposite, as well as the solar light enhanced photocatalytic treatment of Reactive Red 120 (RR120) from genuine wool textile effluent. The 3D flower-like structure of Co-doped ZnO distributed on the surface of CN thin sheets, according to structural studies employing XRD and SEM examinations Electrochemical experiments exhibited that the Co-doped ZnO/CN nanocomposite has a large electroactive surface area. The optical band-gap values of CN, ZnO, ZnO/CN, and Co-doped ZnO/CN nanocomposites were 2.68, 3.13, 2.38, and 2.23 eV, respectively, according to optical characterizations. The synergistic effects and heterojunction produced by Co-doped ZnO and CN can be linked to the narrow gap in nanocomposites. After 75, 60, 50, and 40 min of exposure to solar light, photocatalytic degradation assays for 250 mL of 20 mg/L RR120 solution in the presence of CN, ZnO, ZnO/CN, and Co-doped ZnO/CN nanocomposites demonstrated 100% dye treatment. The applicability of photocatalysts for decolorization of 250 mL of 10 mg/L RR120 prepared from actual wool textile wastewater was investigated, and the results showed that Co-doped ZnO/CN nanocomposites for treatment of RR120 from actual wool textile wastewater were highly efficient at photocatalytic degradation. © 2023

Graph Neural Networks (GNNs) are a family of graph networks inspired by mechanisms existing between nodes on a graph. In recent years there has been an increased interest in GNN and their derivatives, i.e., Graph Attention Networks (GAT), Graph Convolutional Networks (GCN), and Graph Recurrent Networks (GRN). An increase in their usability in computer vision is also observed. The number of GNN applications in this field continues to expand;it includes video analysis and understanding, action and behavior recognition, computational photography, image and video synthesis from zero or few shots, and many more. This contribution aims to collect papers published about GNN-based approaches towards computer vision. They are described and summarized from three perspectives. Firstly, we investigate the architectures of Graph Neural Networks and their derivatives used in this area to provide accurate and explainable recommendations for the ensuing investigations. As for the other aspect, we also present datasets used in these works. Finally, using graph analysis, we also examine relations between GNN-based studies in computer vision and potential sources of inspiration identified outside of this field. © 2022, CC BY-SA.

This paper investigates the secrecy performance of full-duplex cooperative vehicular relaying networks under passive eavesdropping attacks in the presence of co-channel interference. In the considered system model, a static source communicates with a static destination through a mobile full-duplex relay in the presence of a mobile passive eavesdropper and a static co-channel interferer. A closed-form expression for the exact secrecy outage probability of the system is derived for the Nakagami-m fading environment. Hence, the asymptotic secrecy outage probability is obtained at high signal-to-noise values. Numerical and Simulation results are obtained to validate the derived analytical expressions.

Paired electron motion in interacting chains of quantum dots

We study the motion of a pair of electrons along two separate parallel chains of quantum dots. The electrons that are released from the central dot of each chain tend to accompany and not avoid each other. The correlated electron motion involves entanglement of the wave functions which is generated in time upon release of the initial confinement. Observation of the simultaneous presence of electrons at the same side of the chain can provide a fingerprint of the paired electron motion.

The Pauli Exclusion Principle (PEP) is a fundamental pillar of quantum theory. Potential violations of PEP could indicate physics beyond the Standard Model, including existence of extra dimensions, Lorentz invariance violations, or non-commutative space-time geometries. The VIP Collaboration conducts high precision X-ray spectroscopy experiments at INFN’s Gran Sasso Underground National Laboratory to search for atomic transitions that violate PEP. The current VIP-2 experiment, using copper as target material, aims to improve the exclusion limit for PEP violation to β2/2 −31, enhancing the previous constraint by two orders of magnitude. We present our main experimental results so far, and introduce the upcoming experimental upgrade. Additionally, we discuss the VIP-Lead experiment, which specifically explores PEP violations in lead atoms within the context of Non-Commutative Quantum Gravity frameworks. © Copyright owned by the author(s)

Fast evaluation of interaction integrals for confined systems with machine learning

The calculation of interaction integrals is a bottleneck for the treatment of many-body quantum systems due to its high numerical cost. We conduct configuration interaction calculations of the few-electron states confined in III-V semiconductor two-dimensional structures using a shallow neural network to calculate the two-electron integrals, which can be used for general isotropic interaction potentials. This approach allows for a speedup of the evaluation of the energy levels and controllable accuracy.

Hyperspectral images of cultured cells incubated with mesoporous silica-based nanoparticles (NPs) functionalized with phenylboronic acid derivative and loaded with doxorubicin and resveratrol were analyzed to establish incorporation percentage. We designed and developed a digital tool, which extended the standard procedure, by combining spectral angle mapper with assisted segmentation and counting operations. It provides the percentage of pixels in which the spectral fingerprint of the NPs is found. The analysis is carried out at the cell level and points out the similarities and differences between cell lines and types of NPs.

Engineering holography with stabilizer graph codes

The discovery of holographic codes established a surprising connection between quantum error correction and the anti-de Sitter-conformal field theory correspondence. Recent technological progress in artificial quantum systems renders the experimental realization of such holographic codes now within reach. Formulating the hyperbolic pentagon code in terms of a stabilizer graph code, we give gate sequences that are tailored to systems with long-range interactions. We show how to obtain encoding and decoding circuits for the hyperbolic pentagon code, before focusing on a small instance of the holographic code on twelve qubits. Our approach allows to verify holographic properties by partial decoding operations, recovering bulk degrees of freedom from their nearby boundary. Copyright © 2022, The Authors.

COMPACTNESS IN LIPSCHITZ SPACES AND AROUND

The aim of the paper is to characterize (pre)compactness in the spaces of Lipschitz/Hölder continuous mappings, which act from an arbitrary (not necessarily compact) metric space to a normed space. To this end some extensions and generalizations of already existing compactness criteria for the spaces of bounded and continuous mappings with values in normed spaces needed to be established. Those auxiliary results, which are interesting on their own since they use a concept of equicontinuity not seen in the literature, are based on an abstract compactness criterion related to the recently introduced notion of an equinormed *** Codes Primary: 46B50, Secondary: 26A16, 46E15, 46E99 © 2022, CC BY.
