We studied purified bovine factor V (mol wt 330,000) by scanning transmission electron microscopy (STEM) of freeze-dried unstained or negatively contrasted preparations. Freeze-dried molecules revealed discrete shapes ranging from roughly spheroidal (100 to 120 nm) to oblong (140 to 200 nm in length X 50 to 100 nm in width). Oblong shapes could often be resolved into two or three distinct domai...

An approximation technique is considered for computing transmission and reflection coefficients for plane waves propagating through stratified slabs. The propagation of elastic pulse through a planar slab is derived from first principles using straightforward time-dependent method. The paper ends with calculations of enhancement factor for the elastic plane wave and it is shown that it depends ...

Network transmission capability is a key factor that affects the performance of grid. This paper presents an efficient data transmission method in which the serialized data is compressed before and decompressed after it is transmitted through networks. The SOAP extended intercept service is applied as a mean for the compression and decompression process, as a result, the data flow in networks i...

A 25.78-Gbit/s × 4-ch active optical cable (AOC) with an ultra-compact form factor is proposed. The size of the proposed AOC is 5.2 cm3, which is 55% smaller than the standard form factor of Quad Small Form-factor Pluggable (QSFP28), and 45% smaller than that of Micro Quad Small Form-factor Pluggable (μQSFP). As a result of utilizing a high-efficiency heat-dissipation structure and optimizing s...

Hepatitis C virus (HCV) is predominantly transmitted between persons who inject drugs. For this population, global prevalence of HCV infection is high and incarceration is common and an independent risk factor for HCV acquisition. To explore HCV transmission dynamics in incarcerated populations, we integrated virus sequences with risk behavior and spatiotemporal data and analyzed transmission c...

This study determined whether selective transmission of hepatitis C virus (HCV) species occurred among human and chimpanzee recipients of contaminated blood products or plasma containing multiple genotypes, subgenotypes and quasispecies. Commercially prepared factor VIII concentrate (lot DO56), produced prior to HCV testing and inactivation, was subsequently found by direct cloning to contain t...

Transmission properties of chiral metamaterials are investigated through the loss factor. Besides the amplitudes of transmission coefficients of right and left circularly polarized waves, the phases are the other main keys to control the refractive index and chirality of the chiral media, directly affecting the loss factor (LF). The LF is low when the phase combination of circular waves is larg...

The wavelength selective linear absorption in communication C-band is investigated in CMOS-processed PECVD silicon nitride rings. In the overcoupled region, the linear absorption loss lowers the on-resonance transmission of a ring resonator and increases its overall quality factor. Both the linear absorption and ring quality factor are maximized near 1520 nm. The direct heating by phonon absorp...

800x600 background : hepatitis b and c infections have remained major global health burdens during the most recent century. the viral agents responsible for these diseases share common modes of transmission with human immunodeficiency virus (hiv) such as needle-sharing in iv drug abusers. coinfection of hepatitis b or c with hiv increases the rate of progression of chronic liver disease. given ...

Underwater communication networks are currently being developed for use in underwater control systems, underwater telemetry systems, and underwater image transmission systems. The transmission bandwidth and transmission rates of an underwater communication system are low, and its transmission delay is high. In this paper, we propose a direct mapping orthogonal variable spreading factor (OVSF)-b...
