Polysulfide resins,with trade name of  G4 and G112, with short and long chain lengths respectively, were used as reactive modifiers to toughen epoxy resin. The effects of molecular weights of G4 and G112 on impact resistance, dielectric constant, thermal conductivity as well as decomposition  heat and adhesion properties of toughened epoxy were investigated. The impact strength and the diel...

In this contribution, we disclose the ability of α,ω-diene comonomers, namely 1,7-octadiene and 1–10-undecadiene, as long-chain branching (LCB)/cross-linking promoters in ethylene polymerization catalyzed by bis(indenyl) bis(cyclopentadienyl) catalyst systems, rac-{EBTHI}ZrCl2 (Zr-1) (nBuCp)2ZrCl2 (Zr-2). Both under homogeneous heterogeneous (slurry) conditions, Zr-1-based systems efficiently p...

In this work we study the long-time behavior for subcritical measure-valued branching processes with immigration on space of tempered measures. Under some reasonable assumptions spatial motion, and mechanisms, prove existence uniqueness an invariant measure corresponding Markov transition semigroup. Moreover, show that it converges exponential rate to unique in Wasserstein distance as well a de...

Dimethyl ether is under consideration as an alternative diesel fuel. Its combustion chemistry is as yet ill-characterized. Here we use Born-Oppenheimer molecular dynamics (BOMD) based on DFT-B3LYP forces to investigate the short-time dynamics of selected features of the low-temperature dimethyl ether (DME) oxidation potential energy surface. Along the chain propagation pathway, we run BOMD simu...

Renal malformations are a major cause of childhood renal failure. During the development of the kidney, ureteric bud (UB) branching morphogenesis is critical for normal nephrogenesis. These studies investigated whether renal UB branching morphogenesis is altered by a high ambient glucose environment and studied underlying mechanism(s). Kidney explants that were isolated from different periods o...

Glycogen branching enzymes (GBE) or 1,4-alpha-glucan branching enzymes (EC 2.4.1.18) introduce alpha-1,6 branching points in alpha-glucans, e.g., glycogen. To identify structural features in GBEs that determine their branching pattern specificity, the Deinococcus geothermalis and Deinococcus radiodurans GBE (GBE(Dg) and GBE(Dr), respectively) were characterized. Compared to other GBEs described...

This paper studies: (i) the long time behaviour of the empirical distribution of age and normalised position of an age dependent critical branching Markov process conditioned on non-extinction; and (ii) the super-process limit of a sequence of age dependent critical branching Brownian motions.

X-adrenoleukodystrophy (X-ALD) is a complex disease where inactivation of ABCD1 gene results in clinically diverse phenotypes, the fatal disorder of cerebral ALD (cALD) or a milder disorder of adrenomyeloneuropathy (AMN). Loss of ABCD1 function results in defective beta oxidation of very long chain fatty acids (VLCFA) resulting in excessive accumulation of VLCFA, the biochemical "hall mark" of ...
