Thermodynamic features of AdS black holes within the rastall gravity and perfect fluid matter framework
Authors: Laassiri H , Daassou A , Benbrik R 
Published: May 2024

Abstract
In this study, we analyzed the impact of a perfect fluid on the phase transition of Anti-de Sitter (AdS) black holes within the Rastall gravitational background. Compared to similar studies in the literature, the findings of this work are highlighted by the determination of analytical expressions for critical points for charged and Kerr-Newman AdS black holes using approximated formulas for the horizon radius. An accurate analysis of these new analytical expressions allowed us to discover a new viable condition that relates the Rastall parameter κ
λ to the equation of state parameter ω, expressed as:

κ
λ
=

ω

1
+
ω

. Thanks to this new condition, we were able to reproduce all the analytical expressions of critical points calculated within the framework of Einsteinâs general relativity for two cases: a charged AdS black hole and a rotating AdS black hole. These findings suggest that Rastall gravity, considering this new condition, could serve as an alternative theory of gravitation to general relativity. The approximate expression of the horizon radius also enabled the exploration of the distinctiveness of fractional-order phase transitions in these AdS black holes. Furthermore, we calculated the critical exponents, offering insights into the behavior of crucial thermodynamic quantities near the inflection point. Examining how a perfect fluid influences phase transition reveals various critical behaviors, demonstrating that the variation in the phase transition depends on the intensity of the perfect fluid. Notably, this variation is portrayed by a linearly increasing trajectory with the escalation of this intensity.
Simultaneous measurement of temperature and humidity using a dual-parameter sensor based on SPR and no-core fiber technology
Authors: Song Mingshi , Jing Xili , Yin Zhiyong 
Published: May 2024

Abstract
In this article, we present a surface plasmon resonance (SPR) sensor based on a no-core fiber (NCF) structure for simultaneous measurement of temperature and humidity. The sensor is simulated by depositing a silver film on the exterior of the NCF by magnetron sputtering, followed by the application of a composite thin film of polyvinyl alcohol (PVA) and polydimethylsiloxane (PDMS). This configuration induces SPR resonance phenomena at two distinct wavelengths, resulting in the splitting of the resonance peak into two distinct peaks, enabling simultaneous measurement of temperature and humidity. To achieve optimal sensor performance, the thickness of the PDMS-PVA composite film, the proportion of sensitive materials, the thickness of the silver film, and the structural parameters of the fiber were optimized. Simulation results show that the sensor exhibits a humidity sensitivity of 8.60 nm/%RH over a relative humidity (RH) range of 50%–100%. The highest temperature detection sensitivity achieved is 7.40 nm °C−1. This sensor holds great potential for applications in monitoring changes in environmental temperature and humidity.

Published: May 2024

Abstract
The enthralling multiferroic and magnetoelectric characteristics, reasonably higher electrical conductivity, and oxidation resistive nature of the rare earth chromites (RCrO3) (R = rare earth ion) systems with distorted orthorhombic perovskite’s structure have drawn significant curiosity among researchers in the domain of perovskites materials. Though there are copious studies on the numerous ways to synthesize perovskites, but no reviews of the rare-earth chromites could be identified in the literature. Therefore, in this review, we concisely reflect upon the vast literature that has been accumulated in the past years concerning the synthesis, properties and applications of rare-earth chromites.
Braneworlds in warped Einsteinian cubic gravity
Authors: Lessa L.A. , Maluf R.V. , Silva J.E.G. , Almeida C.A.S. 
Published: May 2024

Abstract
Einstenian cubic gravity (ECG) is a modified theory of gravity constructed with cubic
contractions of the curvature tensor. This theory has the remarkable feature of having the same
two propagating degrees of freedom of Einstein gravity (EG), at the perturbative level on
maximally symmetric spacetimes. The additional unstable modes steaming from the higher order
derivative dynamics are suppressed provided that we consider the ECG as an effective field theory
wherein the cubic terms are seen as perturbative corrections of the Einstein-Hilbert term.
Extensions of ECG have been proposed in cosmology and compact objects in order to probe if this
property holds in more general configurations. In this work, we construct a modified ECG gravity
in a five dimensional warped braneworld scenario. By assuming a specific combination of the cubic
parameters, we obtained modified gravity equations of motion with terms up to second-order. For a
thin 3-brane, the cubic-gravity corrections yield an effective positive bulk cosmological
constant. Thus, in order to keep the 5D bulk warped compact, an upper bound of the cubic parameter
with respect to the bulk curvature was imposed. For a thick brane, the cubic-gravity terms modify
the scalar field potential and its corresponding vacuum. Nonetheless, the domain-wall structure
with a localized source is preserved. At the perturbative level, the Kaluza-Klein (KK) tensor
gravitational modes are stable and possess a localized massless mode provided the cubic
corrections are small compared to the EG braneworld.
Radial oscillations of hybrid stars and neutron stars including delta baryons: the effect of a slow quark phase transition
Authors: Rather Ishfaq A. , Marquez Kauan D. , Backes Betânia C. , Panotopoulos Grigoris , Lopes Ilídio 
Published: May 2024

Abstract
We study radial oscillations of hybrid neutron stars composed of hadronic external layers
followed by a quark matter core. We employ a density-dependent relativistic mean-field model
including hyperons and Δ baryons to describe hadronic matter, and a density-dependent
quark model for quark matter. We obtain the ten lowest eigenfrequencies and the corresponding
oscillation functions of N, N+Δ, N+H, and N+H+Δ equations-of-state with a phase
transition to the quark matter at 1.4 and 1.8 M
⊙, focusing on the effects of a slow
phase transition at the hadron-quark interface. We observe that the maximum mass is reached before
the fundamental mode's frequency vanishes for slow phase transitions, suggesting that some stellar
configurations with higher central densities than the maximum mass remain stable even when they
undergo small radial perturbations. Future gravitational wave detectors and multi-messenger
astronomy, complemented by robust microscopic models enabling exploration of various neutron star
compositions, including hyperon content, are anticipated to impose precise limitations on the
equation of state of baryonic matter under high-density conditions.
On the late-time evolution of velocity-dependent self-interacting dark matter halos
Authors: Gad-Nasr Sophia , Boddy Kimberly K. , Kaplinghat Manoj , Outmezguine Nadav Joseph , Sagunski Laura 
Published: May 2024

Abstract
We study the evolution of isolated self-interacting dark matter (SIDM) halos that undergo gravothermal collapse and are driven deep into the short-mean-free-path regime.
We assume spherical Navarro-Frenk-White (NFW) halos as initial conditions and allow for elastic dark matter self-interactions.
We discuss the structure of the halo core deep in the core-collapsed regime and how it depends on the particle physics properties of dark matter, in particular, the velocity dependence of the self-interaction cross section. We find an approximate universality deep in this regime that allows us to connect the evolution in the short- and long-mean-free-path regimes, and approximately map the velocity-dependent self-interaction cross sections to constant ones for the full gravothermal evolution. We provide a semi-analytic prescription based on our numerical results for halo evolution deep in the core-collapsed regime.
Our results are essential for estimating the masses of the black holes that are likely to be left in the core of SIDM halos.

Multi-party semi-quantum secret sharing protocol based on measure-flip and reflect operations
Authors: Li Jian , Ye Chong-Qiang 
Published: May 2024

Abstract
Semi-quantum secret sharing (SQSS) protocols serve as fundamental frameworks in quantum secure multi-party computations, offering the advantage of not requiring all users to possess intricate quantum devices. However, current SQSS protocols mainly cater to bipartite scenarios, with few protocols suitable for multi-party scenarios. Moreover, the multi-party SQSS protocols face limitations such as low qubit efficiency and inability to share deterministic secret information. To address this gap, this paper proposes a multi-party SQSS protocol based on multi-particle GHZ states. In this protocol, the quantum user can distribute the predetermined secret information to multiple classical users with limited quantum capabilities, and only through mutual cooperation among all classical users can the correct secret information be reconstructed. By utilizing measure-flip and reflect operations, the transmitted multi-particle GHZ states can all contribute keys, thereby improving the utilization of transmitted particles. Then, security analysis shows that the protocol’s resilience against prevalent external and internal threats. Additionally, employing IBM Qiskit, we conduct quantum circuit simulations to validate the protocol’s accuracy and feasibility. Finally, compared to similar studies, the proposed protocol has advantages in terms of protocol scalability, qubit efficiency, and shared message types.

Abstract
In iron-based superconductor Fe(Se,Te), a flat band-like feature near the Fermi level was observed around the Brillouin zone center in the superconducting state. It is under debate whether this is the evidence on the presence of the BCS–BEC [Bardeen–Cooper–Schrieffer (BCS), Bose–Einstein condensation (BEC)] crossover in the superconductor. High-resolution laser-based angle-resolved photoemission measurements are carried out on high quality single crystals of FeSe0.45Te0.55 superconductor to address the issue. By employing different polarization geometries, we have resolved and isolated the d
yz
band and the topological surface band, making it possible to study their superconducting behaviors separately. The d
yz
band alone does not form a flat band-like feature in the superconducting state and the measured dispersion can be well described by the BCS picture. We find that the flat band-like feature is formed from the combination of the d
yz
band and the topological surface state band in the superconducting state. These results reveal the origin of the flat band-like feature and rule out the presence of BCS-BEC crossover in Fe(Se,Te) superconductor.

Published: May 2024

Abstract
The interaction between shock waves and multiple cylinders, referred to as shock–cylinder interaction (SCI), is an important phenomenon in science and engineering. However, its underlying physical mechanisms remain unclear. This study entailed the numerical simulation of the aerobreakup of two tandem water columns subjected to a high-speed gas flow by using an adaptive mesh refinement (AMR)-based diffusion-interface model. The objective was to elucidate the changes in water–column deformation patterns over a wide range of Weber numbers. Statistical analysis was performed to examine the deformation of the water columns in vertical directions. Results reveal distinct deformation patterns between the two columns as the Weber number increases. Additionally, an extended exponential stretching law model was devised, and its improved capability to predict the deformation patterns was demonstrated.
Divertor-safe nonlinear burn control based on a SOLPS parameterized core-edge model for ITER
Authors: Graber Vincent , Schuster Eugenio 
Published: May 2024

Abstract
For ITER operations, the range of desirable burning-plasma regimes with high fusion power output will be restricted by various operational constraints. These constraints include the saturation of ITER’s various heating and fueling actuators such as the neutral beam injectors, the ion and electron cyclotron heating systems, the gas puffing system, and the deuterium–tritium pellet injectors. In addition to these actuator constraints, the H-mode power threshold, divertor detachment, and the heat load on the divertor targets may apply limitations to ITER’s operational space. In this work, Plasma Operation Contour (POPCON) plots that map the aforementioned constraints to the temperature-density space are used to investigate which constraints are most limiting towards accessing regimes with high fusion power output. The presented POPCON plots are based on a control-oriented core-edge model that couples the nonlinear density and energy response models for the core-plasma region with SOLPS4.3 parameterizations for conditions in the edge-plasma regions (scrape-off-layer and divertor). Using this control-oriented core-edge model, a nonlinear burn controller, which aims to regulate the plasma temperature and density in the core-plasma region, is constructed in this work. This controller is augmented with an online optimization scheme that governs the control references such that the plasma can be guided towards regimes with high fusion powers while protecting the divertor targets from dangerously high heat loads. A closed-loop simulation study illustrates the capability of this burn control scheme.
Turbulent particle pinch in gyrokinetic flux-driven ITG/TEM turbulence
Authors: Imadera Kenji , Kishimoto Yasuaki , Ishizawa Akihiro 
Published: May 2024

Abstract
Aiming at a fuel supply through particle pinch effects, turbulent particle transport is studied by gyrokinetic flux-driven Ion-Temperature-Gradient/Trapped-Electron-Mode (ITG/TEM) simulations. It is found that ITG/TEM turbulence can drive ion particle pinch by E × B drift (n ≠ 0) when the ion temperature gradient is steep enough. Electron particle pinch is also driven by E × B drift (n ≠ 0) in the case with the steep electron temperature gradient. Such an electron particle pinch can trigger an ambipolar electric field, leading to additional ion particle pinch by not only magnetic drift but also E × B drift (n = 0). These results suggest that a density peaking of bulk ions due to turbulent fluctuations can be achieved by sufficiently strong both ion and electron heating.
A macroporous composite sponge with high water absorbency and active coagulation mechanism for traumatic hemostasis and anti-infection

Published: May 2024

Abstract
The development of a composite sponge with high water absorbency and active coagulation mechanism for traumatic hemostasis and anti-infection remains a challenge. Herein, we developed a composite sponge using gelation, swelling, and freeze-drying methods based on quaternized chitosan, succinimidyl-modified F127, and bioactive glass. The sponge exhibited macroporous structure, high porosity, and water absorbency. When exposed to blood, it strongly interacted with blood cells, promoting their adhesion, aggregation, and activation. Moreover, it activated the intrinsic coagulation pathway. The sponge/powder demonstrated superior hemostatic capacity to commercial gauze, gelatin sponge, Yunnan Baiyao, and chitosan hemostatic powder in rat tail amputation, liver superficial injury, liver resection, and liver semi-perforation wound models. The sponge also presented robust anti-infection activity against methicillin-resistant Staphylococcus aureus and Escherichia coli. Additionally, the sponge showed low cytotoxicity, hemolysis activity, inflammation response, and systemic toxicity, demonstrating its favorable biocompatibility.
Controlled delivery of procyanidin through magnesium oxide nanoparticles (MgO NPs) to improve the activity and mineralization of osteoblasts under oxidative stress in vitro

Published: May 2024

Abstract
Excessive reactive oxygen species (ROS) in the microenvironment of osteoporosis (OP) not only accelerate the bone absorption, but also affect the osteogenic and mineralized effect of osteoblasts. Procyanidins (PC) have been reported to have anti-oxidation effects, but low bioavailability. This study aimed to explore the effect of magnesium oxide nanoparticles (MgO-PC NPs)-loaded PC on the osteogenesis and mineralization of osteoblasts that stimulated by H2O2. PC was loaded onto MgO NPs and characterized by transmission electron microscopy, energy dispersive spectroscopy, dynamic light scattering, and Fourier transform infrared spectroscopy. After primary screening by cytotoxicity assay, MgO-PC NPs containing 20 μM of PC were chosen for further studies. In H2O2-stimulated osteoblasts, dichlorodihydrofluorescein diacetate probe, Cell Counting Kit-8, quantitative real-time polymerase chain reaction, alkaline phosphatase staining/activity and Alizarin red staining were used to detect the ROS production, cell viability and osteogenic and mineralized markers of osteoblasts. PC was loaded onto MgO NPs to successfully receive MgO-PC NPs with a diameter of about 144 nm and negative potential. PC can sustain release from MgO-PC NPs for at least 16 d. The controlled release of PC from MgO-PC NPs can effectively eliminate ROS and thereby promoted the cell activity. Most importantly, the osteogenesis and mineralization of osteoblasts under oxidative stress were also significantly reversed by MgO-PC NPS. Thus, these findings indicate that MgO-PC NPs may be developed as a potential therapeutic strategy for OP.

Abstract
The adverse impacts of Australia’s Millennium Drought on both surface and groundwater hydrological systems are extensively documented. During the Millennium Drought, the Murray Basin experienced a severe rainfall deficit. Our study revisited groundwater table trends in 451 wells within the Murray Basin during the drought from 1997 to 2009. These trends varied, 70% showed significant downward shifts, 19% were insignificant, and 11% even displayed upward trends. The results from K-means clustering analysis indicate a markedly slow recuperation of groundwater levels post-drought. We used multiple regression models to link interannual groundwater dynamics with climate variables, revealing climate as the primary driver of declining groundwater levels. This connection is influenced by land cover and thickness of the vadose zone, resulting in hysteresis effects and spatial variations. In cases with a thick vadose zone and minimal evapotranspiration, the influence of the Millennium Drought on the groundwater system is reduced. The increasing trends may also be related to lateral recharge from mountainous areas, human activities in adjacent irrigation districts, and east-west geostress. Our findings reveal the complex interactions between climate, land characteristics, and groundwater behavior during and after the Millennium Drought, holding significant implications for understanding hydrological processes under extreme drought conditions and for the sustainable management of water resources.
Widespread impacts to precipitation of the East Palestine Ohio train accident

Published: May 2024

Abstract
On 3 February 2023, a Norfolk Southern train derailment occurred in East Palestine, Ohio. The accident and subsequent fire resulted in the emissions of large amounts of hazardous compounds to the ambient atmosphere over many days. We used precipitation chemistry measurements routinely collected by the National Atmospheric Deposition Program (NADP) to estimate the spatial extent and chemical compounds deposited as a result of the accident. Our measurements revealed a large areal impact from the Midwest through the Northeast and likely Canada, and perhaps as far south as North Carolina (portions of 16 states, 1.4 million km2). Observations showed the expected high chloride concentrations, but also unexpectedly high pH (basic) and exceptionally elevated levels of base cations exceeding 99th percentiles versus the historic record. These results were consistent with the meteorological conditions and atmospheric trajectories, and were not due to highly-concentrated low volume precipitation samples or wildfires. The robust measurements of the NADP network clearly show that the impacts of the fire were larger in scale and scope than the initial predictions, and likely due to the uplift from the fire itself entraining pollutants into the atmosphere. A more detailed evaluation of the accident and resulting fire could further refine the full impact of the atmospheric concentrations, dry and wet deposition, and the more specific extent of the spatial impact.
