Influence of the heteroatom on the optoelectronic properties and transistor performance of soluble thiophene-, selenophene- and tellurophene-vinylene copolymers by Al-Hashimi, Mohammed

“…The optical band gap of the polymers is shown to systematically decrease as the size of the heteroatom is increased, mainly as a result of a stabilization of the LUMO energy, resulting in a small band gap of 1.4 eV for P3TeV. …”

Computational approach to unravel the impact of missense mutations of proteins (D2HGDH and IDH2) causing D-2-hydroxyglutaric aciduria 2. by Thirumal Kumar, D

“…The D-2-HGA includes two subtypes: type I and type II caused by the mutations in D2HGDH and IDH2 proteins, respectively. In this study, we studied six mutations, four in the D2HGDH (I147S, D375Y, N439D, and V444A) and two in the IDH2 proteins (R140G, R140Q). …”

Effect of hyperglycemia on EPCs function and regenerative ability by Hendawi, Hadeel Khalil

“…This research aims to test the EPC subtype blood outgrowth endothelial cells (BOECs) and their ability to survive and function under chronic hyperglycemic conditions. For that, we studied BOECs viability, response to shear stress, angiogenesis ability, and barrier function under normoglycemic (5.5mM) and hyperglycemic (25mM) conditions. …”

Overconfident results with the bivariate random effects model for meta-analysis of diagnostic accuracy studies by Furuya-Kanamori, Luis

“…Diaz found that the performance of the bivariate model deteriorates when between-study heterogeneity increases and the number of studies decrease.5 Our simulation studies found similar results—with moderate levels of heterogeneity (tau2 = 1), the coverage probabilities of Se, Sp, and the diagnostic odds ratio (DOR) with the bivariate model dropped below the nominal level.6 Diagnostic accuracy studies usually favor sensitivity over specificity, or vice versa leading to diagnostic 2 × 2 tables with one or more of the cells with low frequency or zero counts. …”

Superior photocatalytic activity of Cu doped NiWO4 for efficient degradation of benzene in air even under visible radiation by Tri N.L.M.

“…This was because Cu effectively acted as novel dopant, which not only affected valence band (VB) top and conduction band (CB) bottom of NiWO4 but also formed a medium energy level between CB and VB of the NiWO4 to decrease its energy band gap and electron-hole recombination rate. …”
