The $\beta$ decay of the neutron-rich $^{134}$In and $^{135}$In was investigated experimentally in order to provide new insights into nuclear structure tin isotopes with magic proton number $Z=50$ above $N=82$ shell. $\beta$-delayed $\gamma$-ray spectroscopy measurement performed at ISOLDE facility CERN, where indium were selectively laser-ionized on-line mass separated. Three $\beta$-decay bra...

With respect to the $\rm H\beta$ full width at half-maximum ($\rm FWHM_{H\beta}$), broad line dispersion ($\sigma_{\rm H\beta}$) was preferred as a velocity tracer calculate single-epoch supermassive black hole mass ($M_{\rm BH}$) suggested by \cite{Yu2020b}. For compiled sample of 311 broad-line active galactic nuclei (AGN) with measured hard X-ray photon index ($z<0.7$), $\sigma_{\rm H\beta}$...

Beta-carbolines are a class of drug which can interact with a high affinity with the benzodiazepine (BDZ) binding site of the GABAA receptor. The present paper, aimed at obtaining a deeper insight into the structure-properties relationships of this class of molecules, reports the crystal structures of four beta-carbolines: ZK93423 (3-carboethoxy-4-methoxymethyl-6-benzyloxy-beta-carboline), ZK91...

We combined multimodal imaging (bioluminescence, X-ray computed tomography, and PET), tomographic reconstruction of bioluminescent sources, and two unique, complementary models to evaluate three previously synthesized PET radiotracers thought to target pancreatic beta cells. The three radiotracers {[(18)F]fluoropropyl-(+)-dihydrotetrabenazine ([(18)F]FP-DTBZ), [(18)F](+)-2-oxiranyl-3-isobutyl-9...

Azospirillum brasilense glutamate synthase (GltS) is the prototype of bacterial NADPH-dependent enzymes, a class of complex iron-sulfur flavoproteins essential in ammonia assimilation processes. The catalytically active GltS alpha beta holoenzyme and its isolated alpha and beta subunits (162 and 52 kDa, respectively) were analyzed using synchrotron radiation x-ray solution scattering. The GltS ...

According to the different nucleotide occupancies of the F(1)-ATPase beta-subunits and due to the asymmetry imposed through the central gamma-subunit, the beta-subunit adopts different conformations in the crystal structures. Recently, a spontaneous and nucleotide-independent closure of the open beta-subunit upon rotation of the gamma-subunit has been proposed. To address the question whether t...

Biphasic calcium phosphate ceramics (BCP) comprising a mix of non-resorbable hydroxyapatite (HA) and resorbable beta-tricalcium phosphate (beta-TCP) are particularly suitable materials for synthetic bone substitute applications. In this study, HA synthesised by solid state reaction was mechanically mixed with beta-TCP, then sintered to form a suite of BCP materials with a wide range of HA/beta-...
