With the rapid improvement of medical consumer electronics (CE), the transmission of multiple images has become increasingly common in the medical field. During the transmission and storage of image data, sensitive information, including medical images, may be accessed by unauthorized parties, resulting in possible privacy violations. Consequently, several multi-image encryption (MIE) algorithms have been proposed to solve this real-world problem. Nevertheless, current MIE schemes exhibit several drawbacks, including insufficient security in permutation and diffusion algorithms, as well as the insensitivity of chaotic maps. This paper presents a new encryption algorithm called DPPAD-IE. The algorithm primarily consists of three components. First, we developed an innovative hyperchaotic map called the 2D Cross Gaussian Hyperchaotic Map (2D-CGHM), which has an expanded chaotic interval and is proficient in producing chaotic sequences with improved pseudorandomness. Second, we introduce a new Dynamic Polyhedra Permutation algorithm (DPP) that successfully alters pixel locations of the image, hence diminishing the connection between neighboring pixels. Third, we propose an Arnold Diffusion algorithm (AD), using chaotic sequences to further encrypt the permuted image. The DPPAD-IE is capable of encrypting images of any quantity and size concurrently. The experimental results confirm that this approach is both robust and effective, capable of defending against various security attacks.

We present a detail study on oxidation behavior and failure mechanisms of an in-situ composite AlCoCrFeNi2.1 eutectic high-entropy alloy (ISC-EHEA) doped with Y and Hf at 1300 °C. We demonstrate that the ISC-EHEA has much stronger resistance to surface rumpling and oxide spallation than two conventional NiCoCrAlYHf alloys (CNAs). Hybrid molecular dynamics (MD) and Monte Carlo (MC) simulations show that the diffusion coefficients of the metal elements in the Al-depletion layer of the ISC-EHEA are 50% lower than those of the CNAs. The low diffusion coefficients lead to low growth stress in the thermally grown Al2O3 scale on the ISC-EHEA and improve the creep resistance of the metal in contact with the scale, thus preventing the occurrence of rumpling. The oxidation rate constant of the ISC-EHEA is ~32% lower in comparison to those of the CNAs, which is attributed to the coarser columnar Al2O3 grains that effectively mitigate grain boundary diffusion. The rumpling-free metal/oxide interface, the low residual stress and the low oxide growth rate for the ISC-EHEA result in strong resistance to scale spallation. Owing to the strong scale/alloy bonding at the interface and the build-up of strain energy during prolonged oxidation, damage in the Al2O3 scale on the ISC-EHEA is initiated as surface cracks rather than interface decohesion. When re-oxidized at 1300 °C, the ingress of oxygen along the surface cracks results in fast growth of new oxides at the metal/oxide interface, which causes local stress concentration, interface crack propagation and scale spallation. © 2023, The Authors.

Structural adhesives are widely used for joining composite components in many industries and crack growth in such materials is far more likely to occur when they are subjected to repeated cyclic loading than to monotonic loading. Whilst the Hartman-Schijve equation for fatigue crack growth (FCG) has been shown to hold for cohesive crack growth in adhesives under Mode I, Mode II and Mixed-Mode I/II loading, little attention has been paid to its ability to capture the effects of the thickness of the adhesive layer. The present paper examines the growth of fatigue cracks, that occurs cohesively through the adhesive layer, in two toughened epoxy adhesives typical of those used in the automotive and the aerospace industries. Firstly, it is established that when the crack growth rate, da/dN, curves are expressed as a function of Δ√G, or ΔG, where G is the energy release-rate, then the crack growth curves are a function of the thickness of the adhesive layer. It is then shown that this dependency vanishes when da/dN is expressed as a function of the crack-driving force, Δκ, as defined by the Hartman-Schijve equation. Therefore, it is suggested that the parameter Δκ appears to be a valid similitude parameter. © 36th Technical Conference of the American Society for Composites 2021: Composites Ingenuity Taking on Challenges in Environment-Energy-Economy, ASC 2021.

In this letter, we propose a control scheme for regulating the voltage in Direct Current (DC) power networks. In contrast with other works in the literature where the loads are assumed to be constant, we consider uncertain time-varying loads described as the outputs of nonlinear dynamical exosystems with uncertain parameters. Based on the output regulation methodology, the proposed control scheme ensures the robust stability of the overall network and achieves voltage regulation in presence of impedance (Z), current (I), and power (P) loads. The simulation results illustrate excellent performance of the proposed control scheme.

BACKGROUND:Diurnal oscillations have been reported on ruminal prokaryotes, but the daily rhythmicity of eukaryotes remains unknown. This study investigated diurnal oscillations of ruminal prokaryotes and eukaryotes under three different feeding managements and rumen fluid transplantation conditions, aiming to elucidate the regulatory mechanisms influencing the dynamic shifts of rumen microbiome through the daily feeding cycle. RESULTS:Quantification and profiling of the microbiota of 288 rumen samples collected from lactating dairy cows (n = 12) every 6-h over 48-h feeding cycles under ad libitum, restricted feeding at daytime and nighttime, respectively, revealed the rhythmicity in the population and abundance of ruminal bacteria, archaea, and protozoa. Under restricted-feeding regimes, 61.99% bacterial genera including Prevotella and Ruminococcus, and 7.19% archaeal species including Methanosphaera sp. ISO3-F5, and 66.93% protozoa genera including Entodinium and Isotricha showed feeding-time-influenced changes in circadian rhythms. However, 4.76% bacterial genera such as Prevotellaceae_UCG-001, and 0.29% archaeal species such as group 12 sp. ISO4-H5 exhibited non-feeding-time affected circadian rhythm pattern shifts. Further analysis of 176 rumen fluid samples collected after rumen fluid transplantation showed the proportion of bacterial, archaeal, and protozoal taxa displayed consistent (including Anaeroplasma and Fibrobacter), inconsistent (including Bacteroidales_UCG-001 and NK4A214_group), gain (including Prevotella and Succinivibrio), and loss (including Butyrivibrio and Mycoplasma) of circadian rhythms over the 48-h to 7-day period after transplantation. Similar circadian patterns were found among feed intake, ruminal volatile fatty acid concentrations, bacterial functions such as glycolysis/gluconeogenesis, and deterministic assembly processes of bacterial communities. However, different circadian patterns (12-h shifts) were observed for rumination time, ru

Reduced Graphene Oxide as an Effective Promoter to the Layered Manganese Oxide-Supported Ag Catalysts for the Oxidation of Ethyl Acetate and Carbon Monoxide

The layered manganese oxide ( δ -MnO 2 )-supported reduced graphene oxide (rGO)-promoted silver catalysts ( x Ag− y rGO/ δ -MnO 2;x and y are the Ag and rGO contents, respectively) were prepared via a polyvinyl alcohol-protected reduction route. Physicochemical properties of these materials were determined using the numerous techniques, and their catalytic activities were evaluated for the oxidation of CO and ethyl acetate. It is found that the doping of rGO as an electron transfer promoter could significantly strengthen the metal−support interaction (SMSI) between Ag and δ -MnO 2 , hence improving catalytic performance of the sample. Activity evaluation reveals that 1Ag−1.0rGO/ δ -MnO 2 performed the best, giving the T 90% of 140 o C for CO oxidation and 160 o C for ethyl acetate oxidation at space velocity (SV) = 60,000 mL/(g h). The doping of rGO led to an increase in Mn3+/Mn4+ or O ads /O latt molar ratio, thus giving rise to the enhancement in catalytic activity of Ag/δ -MnO2 . The good performance of 1Ag−1.0rGO/ δ -MnO 2 was associated with its high Oads /O latt molar ratio, good low-temperature reducibility, and strong SMSI between Ag and δ -MnO2 . © 2022, The Authors.

The Telescope Array Low-energy Extension (TALE) experiment is a project that extends the Telescope Array (TA) experiment to observe cosmic rays with energies down to 1016.5 eV using 10 fluorescence detectors (FDs) and 80 surface detectors (SDs). The TALE-infill SD array, consisting of 50 SDs arranged in a grid pattern with 100-meter spacing, has been installed to extend observations to lower energies, covering the PeV energy region. The extension as TALE-infill enables precise measurements of the energy spectrum, mass composition, and arrival direction anisotropy of cosmic rays around the knee, with the aim of investigating the origin of cosmic rays and the physical mechanisms responsible for the knee feature. In this paper, we report on the observational status of the TALE-infill array, using the first data from November 2023 to Jun 2024. © Copyright owned by the author(s) under the terms of the Creative Commons Attribution-NonCommercial-NoDerivatives 4.0 International License (CC BY-NC-ND 4.0).

The divergence and continuous evolution of plants and animals contribute to ecological *** and transcription factors(TFs) are key determinants of gene regulation and transcription ***,theevolutionary trajectories and relationships of promoters and TFs are still poorly understood. Here, we conducted extensive analysis of large-scale multi-omics sequences in 420 animal species and 223 plant species spanning nearly a billion years of evolutionary history. Results showed that promoter GC-contentandTFisoelectricpoints,as features/signatures that accompany long biological evolution, exhibited increasing growth in animal cells but a decreasing trend in plant cells. Furthermore, the evolutionary trajectories of promoter and TF signatures in the animal kingdom provided further evidence that Mammalia as well as Aves evolved directly from the ancestor Reptilia. The strong correlation between promoter and TF signatures indicates that promoters and TFs formed antagonistic coevolution in the animal kingdom, but mutualistic coevolution in the plant kingdom. The distinct coevolutionary patterns potentially drive the plant-animal divergence, divergent evolution and ecological diversity.

The study of large-scale anisotropy at the highest energies is essential for understanding the transition from cosmic rays of galactic origin to those of extra-galactic origin, along with the magnetic fields in the galaxy and those beyond. Motivated by a significant detection of the large-scale anisotropy above 8 EeV by the Pierre Auger Observatory (Auger), we had previously reported, using 11 years of Telescope Array (TA) surface array data, a result compatible both with that of Auger, and with an isotropic source distribution [1]. In this contribution, we will show the preliminary updated results using 12 years TA SD data to search for the large-scale anisotropy at the highest energies. © Copyright owned by the author(s).
