The self-clocking principle (SCP) of Transmission Control Protocol (TCP) had been analyzed for a network implementing a per-flow buffering scheme. The ideal SCP is yet unknown for the Internet which implements a first-in-first-out buffering scheme. This paper derives an ideal SCP for the Internet by formulating the traffic transmission control into a typical control problem and then solving it ...

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...

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...

Abstract In healthcare, small‐scare data are stored with individual entities, such as hospitals, and they not shared. However, one entity sufficient for training a machine learning model therefore cannot be fully utilized. Given that large amount of small‐scale is widely distributed between hospitals/individuals, it necessary to deploy an easy, scalable, secure computational framework. We aim a...
