A novel bipolar transistor structure, namely, a SiC emitter lateral NPM Schottky collector bipolar transistor (SCBT) with a silicon-on-insulator (SOI) substrate is explored using two-dimensional (2-D) simulation. A comprehensive comparison of the proposed structure with its equivalent Si lateral NPN BJT and an SiC emitter lateral NPN HBT is presented. Based on simulation results, the authors de...

Two Boolean functions are NPN equivalent if one can be obtained from the other by negating inputs, permuting inputs, or negating the output. NPN equivalence is an equivalence relation and the number of equivalence classes is significantly smaller than the number of all Boolean functions. This property has been exploited successfully to increase the efficiency of various logic synthesis algorith...

The two most abundant secreted isoforms of vascular endothelial growth factor A (VEGF(165) and VEGF(121)) are formed as a result of differential splicing of the VEGF-A gene. VEGF(165) and VEGF(121) share similar affinities at the isolated VEGF receptor (VEGFR)-2 but have been previously demonstrated to have differential ability to activate VEGFR-2-mediated effects on endothelial cells. Herein w...

The reduction of high oxidation state metal complexes in the presence of molecular nitrogen is one of the most common methods to synthesize a dinitrogen complex. However, the presence of strong reducing agents combined with the poor binding ability of N2 can lead to unanticipated outcomes. For example, the reduction of [NPN]ZrCl2(THF) (where NPN = PhP(CH2SiMe2NPh)2) with KC8 under N2 leads to t...

Dopaminergic neurons in the mesodiencephalon (mdDA neurons) make precise synaptic connections with targets in the forebrain via the mesostriatal, mesolimbic, and mesoprefrontal pathways. Because of the functional importance of these remarkably complex ascending axon pathways and their implication in human disease, the mechanisms underlying the development of these connections are of considerabl...

In this paper, we give a new similarity measure on npn-soft set theory which is the extension of correlation measure of neutrosophic refined sets. By using the similarity measure we propose a new method for decision making problem. Finally, we give an example for diagnosis of diseases could be improved by incorporating clinical results and other competing diagnosis in npn-soft environment..

Reaction of TlPF(6) with the Cr(III) complex fac-[CrCl(3)(NPN)] (NPN = bis(2-picolyl)phenyl phosphine) did not lead to precipitation of TlCl but rather to addition of the Tl(+) cation to the CrCl(3) moiety, which resulted in a pseudo-dimeric adduct which has an unusual tetranuclear centrosymmetric structure in the solid state.

After a spinal cord lesion, a myriad of axon growth inhibitors present in myelin and in the neural scar contribute to the failure of injured axons to regenerate. Class 3 semaphorins are repulsive axon guidance cues that are induced in the meningeal fibroblasts that infiltrate the neural scar. Most if not all injured spinal cord neurons, including neurons that form the corticospinal tract (CST),...

We derive estimates for the largest and smallest singular values of sparse rectangular N×n random matrices, assuming limN,n→∞n N=y∈(0,1). consider a model with sparsity parameter pN such that NpN∼logαN some α>1, assume moments matrix elements satisfy condition E|Xjk|4+δ≤C<∞. also entries matrices we are truncated at level (NpN)1 2−ϰ ϰ:=δ 2(4+δ).

Two experiments were conducted to examine the impact of source, urea (U) or Optigen II (OP), and level of dietary NPN on performance (Exp.1) and N balance (Exp. 2) of growing cattle. Sixty Angus crossbred steers (initial BW = 353 ± 13.9 kg) were used to evaluate performance, and fed 1 of 3 steam-flaked corn based diets: U (U(1.2), 1.2% NPN), OP (OP(1.3), 1.3% NPN), or OP without cottonseed meal...
