The human beta-globin locus control region (LCR) consists of four erythroid-specific DNaseI hypersensitive sites (HSs) at the 5' end of the beta-globin cluster. The LCR functions over a long distance on chromosome 11 to regulate transcription and replication of the beta-globin genes. To determine whether the HSs function independently or as an integrated unit, we analyzed the requirements for l...

Haishengsu (Hss) is a purified protein from Tegillarca granosa that has been used as a traditional Chinese medicine to treat cancer for more than a century. In this study, we observed the impact of Haishengsu (Hss) on the proliferation and differentiation of HL-60 cells in the leukemic cell line by taking tretinoin and AS2O3 as a positive control and making a comparative analysis between the ef...

Hierarchically semiseparable (HSS) matrix algorithms are emerging techniques in constructing the superfast direct solvers for both dense and sparse linear systems. Here, we develope a set of novel parallel algorithms for the key HSS operations that are used for solving large linear systems. These include the parallel rank-revealing QR factorization, the HSS constructions with hierarchical compr...

This paper presents the experimental results regarding acoustic emission signals measured during the injection molding of those standard test specimens commonly used for examining the shrinkage behaviour of various thermoplastic materials. In daily industrial production of different plastic products we often have to deal with various errors that practically occur on the mold primarily as a resu...

Abstract. Dynamic recrystallization of high-speed steel (HSS) M2 occurs through a discontinuous mechanism, involving nucleation and growth strain-free grains. The initiation completion dynamic (dDRX) must be carried out in single rolling pass. time for 99% dDRX depends on the critical strain, strain rate equivalent that generated workpiece material level plays key role terms possibility to comp...

Accurately obtaining the material parameters of damage model is very important for ductile fracture simulation steel structures made high strength (HSS). The combination micromechanics with uncoupled phenomenological can be used to obtain locus only from uniaxial engineering stress-strain relationship. A micro failure index generally link under different multiaxial stress status. It relatively ...

Abstract In this paper, the effect of autogenous diode laser beam welding (LBW) and influence post weld heat treatment (PWHT) on microstructural changes mechanical properties dual phase DP1400 high strength steel (HSS) butt welded joint are studied presented. LBW PWHT were performed 1 mm sheet thickness using 3 5 kW systems, respectively. The technology ensures quality joints in HSS facilitate ...

The microstructure and wear behavior of S390 high-speed steel (HSS) reinforced with different volume fractions MC-type carbides produced via spark plasma sintering were investigated using scanning electron microscopy (SEM) transmission (TEM) in this study. SEM TEM results show that V-W-rich are formed around the added carbides, these have a similar composition to M(C, N) precipitated at high te...
