Gamma-ray bursts (GRBs) are a promising probe of the high-redshift Universe, but their detection remains observationally challenging. In this work, we explore the detectability of high- z GRBs by the Wide-field X-ray Telescope (WXT) on board the Einstein Probe (EP) and the coded-mask gamma-ray image...

We report on the lasing action in weakly modulated parity-time (PT) symmetric lattices. At the exceptional point in PT-symmetric lattices, the amplitude and phase of unidirectionally scattered waves are independently and flexibly determined by the PT modulations, thus, providing a distinctive route...

In order to solve the problems of lack and low accuracy of 3D reconstruction due to saturation of strong reflection of workpiece surface, a method combining phase fusion and multi-frequency heterodyne algorithm is proposed in this paper. Firstly, the influence of workpiece surface brightness saturat...

BackgroundCurrently, nintedanib and pirfenidone are the two primary pharmacological agents used to treat pulmonary fibrosis (PF). However, neither of these medications effectively halts the progression of PF or preserves lung function. As a result, lung transplantation remains the sole viable treatm...

Citrus tristeza virus (CTV) is one of the most important causal agents of citrus diseases and exists as numerous strains. CTV is replicated in phloem cells of plants within the family Rutaceae and is transmitted by a few of aphid species. CTV epidemics have caused death of millions of citrus trees i...

Salt stress contains osmotic and ionic stress, while iso-osmotic polyethylene glycol (PEG) has only osmotic stress. This study aimed to compare the different effects on the activity of H+-ATPase, proton pump and Na+/H+ antiport in Malus seedlings between osmotic and ionic stress. Species of salt tol...

We investigated the correlation between leaf/soil minerals and fruit quality in apple trees grown in orchards, with the ultimate goal of improving the latter. Leaf mineral nutrients; soil nutrients in the 0–20, 20–40, and 40–60 cm layers; and fruit quality traits in 32 apple orchards in China were m...

Citrus Huanglongbing (HLB, yellow shoot disease) is one of the most serious citrus diseases worldwide. To better improve the detection sensitivity, a droplet digital PCR (ddPCR) assay was developed for the rapid detection of ‘Candidatus Liberibacter asiaticus’ (Las), the putative causal agent of HLB...
