Against the backdrop of the current rural economic transformation and the intensification of the ageing process, land transfer, as an important land policy tool, has gradually become a key factor influencing the consumption behaviour of farmers, especially older farmers. Based on the four-period pan...

Abstract Polarization is a prominent feature of gravitational wave observations and can be used to distinguish between different modified gravity theories. Compared to General Relativity, f(R) gravity exhibits an additional polarization originating from a scalar field, which is a combination of the...

Temporal patterns of vitellogenin (Vg) synthesis and uptake as well as vitellin (Vn) degradation in Nasonia vitripennis (Hymenoptera: Pteromalidae), an ectoparasitic wasp of fly pupae, were studied using the method of enzyme-linked immunosorbent assay (ELISA). The results were showed as follows: the...

This article investigates reinforcement learning (RL)-based solutions for optimizing resource allocations in simultaneous lightwave information and power transfer (SLIPT) under practical indoor mobility. Encountering the challenges of excessive outages and intermittent channels posed by practical mo...

Influences of 10 insecticides at commercially recommended dosage on survival of Pteromalus puparum female adults, as well as 4 of them on the ovarian development of surviving adults, were evaluated in laboratory using dry film bioassay. Based upon the mortality of treated adults, phoxim and chlorpyr...

BackgroundStenotrophomonas maltophilia, an important opportunistic pathogen resistant to multiple antibiotics, necessitates alternative therapies. Phages, with their high specificity and bacteriolytic ability, are emerging as promising antibiotic alternatives. This study aimed to isolate and charact...

BackgroundAcinetobacter baumannii is a common hospital pathogen that poses a serious clinical challenge due to its rapidly increasing resistance to antibiotics. Phage therapy has been successfully used to treat antibiotic resistant A. baumannii infections. The aim of this study was to comprehensivel...

The ultrastructures of fat bodies before and during vitellogenesis and of follicles at different developmental stages in the parasitoid Pteromalus puparum were studied by electron microscope. At previtellogenic stage (that is, at pupal stage), large amounts of protein granules and mitochondria were...

This paper presents a learning-assisted approach for state estimation of quadruped robots using observations of proprioceptive sensors, including multiple inertial measurement units (IMUs). Specifically, one body IMU and four additional IMUs attached to each calf link of the robot are used for sensi...

The plasma response to the n  = 1 resonant magnetic perturbation in EAST has been systematically investigated using the MARS-F/Q codes, focusing on the roles of q _95 and $\beta_\mathrm N$ in error field penetration. Here, q _95 refers to the safety factor at 95% poloidal magnetic flux, which is var...

Due to the increasing penetration of renewable energy, the power inertia will keep decreasing in the future. To deal with the decreasing of power system inertia and prevent cascading failure, the frequency dynamics constraints are modeled considering frequency nadir and rate of change of frequency....

Soil water deficit and salt stress are major limiting factors of plant growth and agricultural productivity. The primary root is the first organ to perceive the stress signals for drought and salt stress. In this study, maize plant subjected to drought, salt and combined stresses displayed a signifi...

Low back pain (LBP) has long been the leading cause of worldwide productivity loss and the top cause of years lived with disability. Observational studies have reported associations between brain imaging-derived phenotypes (IDPs) and LBP; however, it is uncertain whether these relationships are caus...

Background Excessive immune‐mediated inflammatory reactions play a deleterious role in postinfarction ventricular remodeling. Interleukin‐37 (IL‐37) emerges as an inhibitor of both innate and adaptive immunity. However, the exact role of IL‐37 and IL‐37 plus troponin I (TnI)–treated dendritic cells...
