Abstract The Follow-up X-ray Telescope (FXT) is one of the two main scientific instruments on board Einstein Probe astronomical satellite, which was launched in 2024 January. FXT focuses energy range 0.3–10 keV and mainly conducts follow-up observations transients burst sources. It consists units completely independent optical system detector (FXT-A FXT-B). focal plane adopts PNCCD provided by Max Planck Institute for Extraterrestrial Physics. designed to have three operating modes with...
Abstract The 100-m X-ray Test Facility of the Institute High Energy Physics (IHEP) was initially proposed in 2012 for test and calibration detectors Hard Modulation Telescope (HXMT) with capability to support future missions. large instrument chamber connected a long vacuum tube can accommodate mirror, focal plane detector other instruments. sources are installed at end distance 105 m, which provide an almost parallel beam covering 0.2 $$\sim$$ <mml:math...
The Einstein Probe (EP) is an X-ray astronomical mission mainly devoting to time-domain astronomy. There are two main scientific payloads onboard EP, the Wide Field Telescope (WXT) based on lobster eye optics and Follow-up (FXT). FXT contains Wolter-1 mirrors with a pnCCD detector each focus. total effective area about 600 cm2 energy range 0.3-10 keV. cooled by pulse tube cooler enables high-resolution spectroscopy imaging combined excellent time resolution. It will also have several working...

In this work, we study...
Periphytic algae exist widely in different waters. However, little is known about periphytic long-distance water diversion channels across watersheds. We investigated the and environmental factors at twenty sampling sites middle route of South-to-North Water Diversion Project (MRP). The dominant species were Desmodesmus intermedius (Hegewald), Calothrix thermalis (Bornet & Flahault), parietina Flahault) Leptolyngbya benthonica (Anagnostidis) (dominance > 0.02) as measured a whole...
Astrocytes are the primary cell type in central nervous system, responsible for maintaining stability of brain’s internal environment and supporting neuronal functions. Researches have demonstrated close relationship between astrocytes pathophysiology etiology major depressive disorder. However, regulatory mechanisms during depression remain unclear. The aim this study is to examine alterations calcium signaling dorsal raphe nucleus (DRN), neurons both DRN medial prefrontal cortex (mPFC),...
Abstract The Einstein Probe (EP) mission, launched in 2024 January, is a time-domain X-ray satellite designed to discover and study transient burst sources while investigating electromagnetic counterparts gravitational waves. To achieve precise observations, EP features the Follow-up Telescope (FXT), equipped with two Wolter-I type mirrors for imaging within 1 square degree field of view. A specialized Ray-Tracing package FXT (RTF) was developed assess mirrors’ performance used FXT. By...
Background Apalutamide is used in the treatment of castration-resistant prostate cancer. A simple, specific, selective, and effective liquid chromatography–tandem mass spectrometry method for quantifying apalutamide its active metabolite concentration human plasma was developed validated according to FDA EMA validation guidelines. Methods total 24 patients diagnosed with desmoplasia-resistant cancer (NM-CRPC) were recruited. Blood samples drawn after 4 weeks’ administration at a dose 180 mg...
The nested Wolter-I type focusing mirror is widely used in the field of X-ray astronomy. thin-shell mirrors produced by electroforming replication method will introduce various shape errors during fabricating and assembling process. This study introduces a non-analytical 3D geometrical ray tracing algorithm capable predicting optical performance for large deformations. algorithm's implementation involves error reconstruction, light source simulation, calculation. Experimental simulation...
The South-to-North Water Division Middle Route Project (MRP) is currently the longest inter-basin water diversion project in world. It benefits a large population and its quality has attracted much attention. In this study, seasonal investigations on 11 sampling sites along MRP were conducted from 2018 to 2019; temperature, pH, turbidity, transparency, COD Mn , dissolved oxygen, total phosphorus, phosphate, nitrogen, ammonia, nitrate, chlorophyll determined synchronously. Single leakage...
