The New Space technology Test Satellite (SY-01) is scheduled to carry out its first flight with a Chinese aerospace rocket, carrying multiple payloads to carry out space scientific exploration missions. SY-01 can carry multiple payloads to carry out space exploration missions. Among them, the High Energy Burst Researcher (HEBS) is one of the important payloads on the satellite. It will monitor the high-energy electromagnetic counterparts of gravitational wave events throughout the day and discover large samples of gamma-ray bursts. This paper mainly introduces the ground test experiment of the HEBS payload gamma-ray detector (GRD) and studies energy resolution and energy linearity in the range of (38–80)keV. The test results show that the GRD has good performance in the low-energy region, which can meet the requirements of monitoring gravitational wave gamma-ray bursts on-orbit.

In order to improve the radon adsorption efficiency of activated carbon and provide a reference for reducing the cost of radon purification, the radon adsorption experiment of activated carbon under different gas superficial velocities under the active adsorption mode was studied to measure the radon adsorption quantity of activated carbon. The radon adsorption quantity of apricot shell activated carbon and coal-based activated carbon did not change significantly with the increase of the gas superficial velocity. When the gas superficial velocity increased from 0.9cm/s to 2.0cm/s in turn, the radon adsorption quantity of coconut shell activated carbon did not change significantly. The radon adsorption quantity of coconut shell activated carbon increased first and then decreased when the gas superficial velocity increased from 2.0cm/s to 3.1cm/s. When the gas superficial velocity was about 2.7cm/s, the radon adsorption quantity of coconut shell activated carbon reached its peak value. 2.7cm/s can be selected as the optimum gas superficial velocity for the radon adsorption of coconut shell activated carbon. © Published under licence by IOP Publishing Ltd.

West Africa experiences rising carbon emissions driven by rapid urbanization, population growth, and continued dependence on fossil fuels. Despite increasing interest in renewable energy, regional analyses often fail to capture the nonlinear and distributional effects of different energy sources on emissions. Addressing this gap, we investigates how six renewable energy sources influence emissions across varying pollution levels using long-term data (1990–2100) and advanced modeling techniques. Generalized Additive Models (GAM) and Quantile Regression (QR) were employed to assess both average and distribution-specific impacts. The GAM model demonstrated strong predictive performance (R 2 = 0.996), with deviance explained and error metrics supporting its reliability, indicating that solar and wind energy reduces emissions significantly, particularly in high-pollution scenarios. QR findings showed biomass becomes more effective at higher emission quantiles, while hydropower and nuclear consistently reduce emissions across all quantiles. Additionally, evidence of GDP-emission decoupling at higher quantiles suggests that economic growth can align with emissions reductions. The findings reveal asymmetric impacts across the emissions spectrum, offering a theoretical extension to energy transition models through a dual heterogeneity framework. These insights highlight the importance of context-specific strategies like targeting wind and solar in high-emission areas, promoting biomass in rural zones, and expanding hydropower and nuclear where feasible, informing a more nuanced and effective decarbonization pathways in West Africa.

We investigate exotic neutrino interactions using the 205.4−kg·day dataset from the CDEX-10 experiment at the China Jinping Underground Laboratory. New constraints on the mass and couplings of new gauge bosons are presented. Two nonstandard neutrino interactions are considered: a U(1)B–L gauge-boson-induced interaction between an active neutrino and electron/nucleus, and a dark-photon-induced interaction between a sterile neutrino and electron/nucleus via kinetic mixing with a photon. This work probes an unexplored parameter space involving sterile neutrino coupling with a dark photon. New laboratory limits are derived on dark photon masses below 1 eV/c2 at some benchmark values of Δm412 and g′2sin22θ14.

A formation control strategy with collision avoidance and obstacle avoidance mechanisms is proposed for second-order continuous multi-agent systems (MAS) under a directed topology. The control objectives can be achieved by introducing artificial potential field (APF) methods and the leader-follower formation methods. The leader-follower formation methods are employed to assist follower agents to obtain the coordination of positions and consensus of velocities with the leader-agent, the control objectives of formation generation and formation maintenance can be achieved. In the APF methods, obstacles and agents are regarded as high potential fields. The repulsive forces provided by the potential fields can solve the problems of avoiding collisions among agents and avoiding the extern-obstacles. By using Lyapunov stability theory and graph theory, the fact, the stability of the closed-loop MAS can be guaranteed, is proven. In the end, the simulation results verified the effectiveness of the proposed formation control strategy. © 2020 IEEE.

In this paper, the security issue of cache-enabled wireless networks is considered, where data transmission from the small base station (SBS) to the user is interfered by denial-of-service (DoS) attacks. To deal with this type of DoS attacks, we firstly investigate the energy dispatch problem from the perspective of the SBS. We further establish an optimization model by using the average number of subfiles requested from the macro base station (MBS) to measure the system performance, and then present the corresponding algorithm to derive the optimal scheduler. Additionally, numerical simulations are carried out to validate the effectiveness of the proposed algorithm. © 2020 IEEE.

We perform a search of double beta decay of 136Xe to the excited state, 0+1 , of 136Ba (2νββ-0+1 ), using the dual-phase xenon detector of PandaX-4T with the first 94.9-day commissioning data. The multi-site events are reconstructed up to the MeV energy scale, which helps to improve the background model significantly. The background contribution from the stainless steel platform outside PandaX-4T cryostat is evaluated for the first time. No significant evidence for 2νββ-0+1 is observed, resulting in a lower limit on half-life of 7.5×1022 yr at the 90% confidence level. This is the first experimental limit on such a rare decay in a natural xenon-based detector. © 2025, CC BY.

The temperature and flow rate of coolant in the hot legs of pressurized water reactor (PWR) systems directly reflect the nuclear power and the heat transfer state of the reactor core, and are key parameters for reactor power control and safety protection. Most of existing studies have been conducted to analyze the steady-state thermal hydraulic features in the upper plenum and hot legs from a spatial scale, but less from a temporal scale to describe and analyze the transient features. In order to meet the requirements of key parameters measurement and safe operation, this paper established a reasonably simplified 3D geometrical model of the upper plenum and hot legs of the HPR1000 reactor based on a multi-physics field simulation platform and investigated the steady-state and transient features of the flow-thermal coupling field of coolant under numerical simulation, focusing on the coupling analysis of the flow-thermal coupling field on the spatial and temporal scales. The analysis of the steady-state features shows that the coolant flowing into the upper plenum from the upper core plate is characterized by a high middle temperature and a low peripheral temperature. As a result, there is an uneven coolant temperature distribution at the inlet of the hot legs that the temperature differences between the cold lower part and hot upper part are relatively large. However, with the axial flow of coolant, the temperature distribution in hot legs tends to be more uniform and the temperature differences decrease. The simulation results show that the flow of the low temperature coolant in hot legs dominates the change of coolant temperature distribution. The analysis of the transient features shows that a small fluctuation of flow rate at the core outlet causes changes in the turbulent kinetic energy of coolant in hot legs, but the effect on coolant temperature distribution is relatively weak. These such variations on the temporal scale can change the coupling relations of c

Lattice dynamics and elastic properties of α-U at high-temperature and high-pressure by machine learning potential simulations

Studying the physical properties of materials under high pressure and temperature through experiments is difficult. Theoretical simulations can compensate for this deficiency. Currently, large-scale simulations using machine learning force fields are gaining popularity. As an important nuclear energy material, the evolution of the physical properties of uranium under extreme conditions is still unclear. Herein, we trained an accurate machine learning force field on α-U and predicted the lattice dynamics and elastic properties at high pressures and temperatures. The force field agrees well with the ab initio molecular dynamics (AIMD) and experimental results and it exhibits higher accuracy than classical potentials. Based on the high-temperature lattice dynamics study, we first present the temperature-pressure range in which the Kohn anomalous behavior of the Σ4 optical mode exists. Phonon spectral function analysis showed that the phonon anharmonicity of α-U is very weak. We predict that the single-crystal elastic constants C44, C55, C66, polycrystalline modulus (E, G), and polycrystalline sound velocity (CL, CS) have strong heating-induced softening. All the elastic moduli exhibited compression-induced hardening behavior. The Poisson's ratio shows that it is difficult to compress α-U at high pressures and temperatures. Moreover, we observed that the material becomes substantially more anisotropic at high pressures and temperatures. The accurate predictions of α-U demonstrate the reliability of the method. This versatile method facilitates the study of other complex metallic materials. © 2022, CC BY.
