InPBi was predicted to be the most robust infrared optoelectronic material but also difficult synthesize within In-VBi (V = P, As and Sb) 25 years ago. We report first successful growth of single crystals with Bi concentration far beyond doping level by gas source molecular beam epitaxy. The thin films reveal excellent surface, structural optical qualities making it a promising new III–V compound family member for heterostructures. is found 2.4 ± 0.4% 94 5% atoms at substitutional sites....
Context. Solar flare prediction models normally depend on properties of active regions, such as sunspot area, McIntosh classifications, Mount Wilson and various measures the magnetic field. Nevertheless, positional information regions has not been used.
We propose a compact, broadband, and low-loss polarization beam splitter (PBS) based on an asymmetrical directional coupler the lithium-niobate-on-insulator platform, consisting of amorphous silicon (a-Si) assisted waveguide, normal waveguide. With proper design a-Si nanowire, lithium niobate waveguides, phase-matching condition is satisfied for TE polarization, while significant mismatching exists TM polarization. A 16-μm-long PBS (including s-bend region) with 200 nm gap achieved....
Transforming growth factor-β2 (TGF-β2) induced fibrogenic changes in human trabecular meshwork (HTM) cells have been implicated (TM) damage and intraocular pressure (IOP) elevation primary open-angle glaucoma (POAG) patients. Silibinin (SIL) exhibited anti-fibrotic properties various organs tissues. This study aimed to assess the effects of SIL on TGF-β2-treated HTM elucidate underlying mechanisms. Our found that effectively inhibited cell proliferation, attenuated TGF-β2-induced migration,...
We propose to develop a wide-field and ultra-high-precision photometric survey mission, temporarily named "Earth 2.0 (ET)". This mission is designed measure, for the first time, occurrence rate orbital distributions of Earth-sized planets. ET consists seven 30cm telescopes, be launched Earth-Sun's L2 point. Six these are transit telescopes with field view 500 square degrees. Staring in direction that encompasses original Kepler four continuous years, this monitoring will return tens...
Abstract The measurement of cosmic-ray individual spectra provides unique information regarding the origin and propagation astro-particles. Due to limited acceptance current space experiments, protons nuclei around “knee” region (∼ 1 PeV) can only be observed by ground based experiments. Thanks an innovative design, High Energy cosmic-Radiation Detection (HERD) facility will allow direct observation up this energy region: instrument is mainly on a 3D segmented, isotropic homogeneous...
A Nd:GdVO4 crystal is pumped directly into its emitting level at 913 nm for the first time to best of our knowledge. 3.35 W output laser 1063 achieved in a 1.1 at.% Nd-doped Nd:GdVO4. The absorbs pumping light 4.30 and produces very low quantity heat with opto-optic conversion efficiency 77.2%. average slope 81.2% from 0.21 W, threshold, absorbed pump power. Because weakly thermal effect, near-diffraction-limit beam easily obtained quality factor M2 ≈ 1.1.
Context.Recently, it was found that two persistent active longitudes of sunspots separated by about existed on the sun considering a dynamic reference frame inferred from differential rotation law. The same phenomenon in longitudinal distribution powerful X-ray flares.
We report a passive mode-locked Nd:YVO4 laser pumped by 880 nm LD using transmission-type multi-walled carbon nanotube saturable absorber. At the pump power of 6.1 W, average output 0.8 W continuous wave with optical conversion efficiency 13.1% was generated. The repetition rate and pulse energy were 88 MHz 9.1 nJ, respectively.
Context. Active longitudes have been found in various manifestations of solar activity. The longitudinal distribution of, e.g., sunspots and X-ray flares shows two persistent preferred separated by roughly 180 degrees. We previously studied using an improved version a dynamic, differentially rotating coordinate system enhanced rotational asymmetry rotation parameter values that are consistent for the three classes flares.
Context. Solar active longitudes and their rotation have been studied for a long time using various forms of solar activity. However, the results on long-term evolution rates hemispheric asymmetry obtained by earlier authors differ significantly from each other.
GeSn alloy with 7.68% Sn concentration grown by molecular beam epitaxy has been rapidly annealed at different temperatures from 300°C to 800°C. Surface morphology and roughness below or equal 500°C for 1 min have no obvious changes, while the strain relaxation rate increasing. When annealing temperature is above 600°C, significant changes occur in surface roughness, precipitation observed 700°C. The structural properties are analyzed reciprocal space mapping symmetric (004) asymmetric (224)...
Context. After considering the solar surface differential rotation, it was found that two persistent active longitudes of sunspots and X-ray flares, separated by about 180 degrees, exist on sun.

Despite the exciting progress of bifunctional degrader molecules, also known as proteolysis-targeting chimeras (PROTACs), rapidly expanding field is still significantly hampered by lacking available E3 ligase ligands. Our research bridges this gap uncovering a series small-molecule ligands to TRIM21 through DNA-Encoded Library (DEL) technology. We confirmed their interaction with using crystallography and demonstrated anti-proliferative effects across various cancer cell types. Furthermore,...
There is a major public health threat posed by antibiotic resistance around the world. Tigecycline overcomes mechanisms of traditional tetracyclines and often seen as final resort in combating infections caused bacteria resistant to multiple drugs. However, introduction new mobile tet(X) tetracycline destructases leading notable rise tigecycline resistance. Therefore, rapid detection method needed monitor spread In this study, novel liquid chromatography-tandem mass spectrometry (LC-MS/MS)...
