Comparison of human astrocytes (1181N1 line) and sheep choroid plexus cells (SCP) infected with visna virus (V-1181N1 and V-SCP) shows that the mode of virus assembly and the morphology and size of the free virions are identical in the 2 systems. V-SCP cells usually cytolyse soon after infection; V-1181N1 cells do not. This is considered to be due to interference with membrane assembly in the f...

Humans evolved in Africa, but where and how remain unclear. Here it is proposed that the southern coastal plain (SCP) of South Africa may have served as a geographical point of origin through periodic expansion and contraction (isolation) in response to glacial/interglacial changes in sea level and climate. During Pleistocene interglacial highstands when sea level was above 75 m human populatio...

The motivations for deploying energy and spectral-efficient network architectures are the high consumption need more spectral resources in modern cellular networks. key method to solve efficiency EE maximization problem of downlink non-orthogonal multiple access (NOMA)-based massive MIMO system is decouple it into user pairing efficient power allocation problems. This work studies performance t...

Silicone-cyclophosphazene (SCP) as a flame retardant was synthesized using hydroxyl terminated polydime thylsiloxane(PDMS-OH) and hexa cyclophosphazene silicone oil and phosphonitrilic chloride trimer(HCCTP) as the precursors, The properties of SCP-modified polycarbonat(PC) such as thermal stability, flame retardant properties and carbon layer after combustion were analyzed. It was found that t...

Given a quantum many-body system, the Self-Consistent Phonons (SCP) method provides an optimal harmonic approximation by minimizing the free energy. In particular, the SCP estimate for the vibrational ground state (zero temperature) appears to be surprisingly accurate. We explore the possibility of going beyond the SCP approximation by considering the system Hamiltonian evaluated in the harmoni...

One of the fundamental tasks for analytic activity is retrieving (i.e., reading) the value of a particular quantity in an information visualization. However, few previous studies have compared user performance in such value retrieval tasks for different visualizations. We present an experimental comparison of user performance (time and error distance) across four multivariate data visualization...

Host factors that enable dengue virus (DENV) to propagate in the mosquito host cells are unclear. It is known that cellular cholesterol plays an important role in the life cycle of DENV in human host cells but unknown if the lipid requirements differ for mosquito versus mammalian. In mosquito Aedes aegypti, sterol carrier protein 2 (SCP-2) is critical for cellular cholesterol homeostasis. In th...

BACKGROUND & AIMS Sterol carrier protein 2 (SCP-2) enhances sterol cycling and facilitates cholesterol translocation between intracellular organelles and plasma membrane in cultured cells, including hepatocytes. We examined the role of SCP-2 in hepatic cholesterol and lipid trafficking through the sinusoidal and canalicular secretory pathways of the liver in vivo. METHODS Recombinant adenovir...

This paper argues that sustainable consumption and production (SCP) should play a prominent role in the formulation and implementation of the sustainable development goals (SDGs) and discusses how this could be practically done. Unsustainable patterns of consumption and production have been declared the primary cause of environmental deterioration. This was clearly recognized already at the Uni...

The individual and interactive effects of Schisandra chinensis powder (SCP) and sodium nitrite additions on color, pH, water holding capacity, residual nitrite, 2-thiobarbituric acid reactive substances (TBARS), volatile basic nitrogen, texture properties, fatty acids, amino acids and sensory evaluation of cooked pork sausages were investigated after 20 d of storage at 4°C. The powders (0, 0.5 ...
