We develop a conceptual model of the economic value of space solar power (SSP) as a source of power to in-space activities, such as spacecraft and space stations. We offer several estimates of the value based on interviews and published data, discuss technological innovations that may compete with or be complementary to SSP, and consider alternative institutional arrangements for government and...

In distributed storage system, storage service provider (SSP) is a critical component to receive and response these requests from clients. We propose a real-time and flexible management of SSP in this paper. With the advantages from virtualization and cloud computing, the states of SSP main VM are observed by another isolated virtual machine, and the administrator can inspect the storage servic...

Abundances and interactions among biological control insects and their effects on target invasive plants were monitored within the flower heads and roots of diffuse knapweed, Centaurea diffusa, and in spotted knapweed, Centaurea stoebe, along the Colorado Front Range. Flower weevils, (Larinus species) and root-feeders (Cyphocleonus achates and Sphenoptera jugoslavica) were released on knapweed ...

It has been well documented how language specific cues may be used for word segmentation. Here, we investigate what role a language-independent phonological universal, the sonority sequencing principle (SSP), may also play. Participants were presented with an unsegmented speech stream with non-English word onsets that juxtaposed adherence to the SSP and transitional probabilities. Participants ...

the cd1 family is less variable transmembrane antigen presenting molecules related to the mhc molecules. cd1a and cd1e genes are the most polymorphic ones associated with autoimmune diseases. the aim was to better clarify the map of cd1 genes in southwest iranian normal population for implications in vaccine design.in this study we investigated the polymorphism of cd1a, cd1d and cd1e in 311 hea...

The envelope glycoprotein of the Junín arenavirus (GP-C) mediates entry into target cells through a pH-dependent membrane fusion mechanism. Unlike other class I viral fusion proteins, the mature GP-C complex retains a cleaved, 58-amino-acid signal peptide (SSP) as an essential subunit, required both for trafficking of GP-C to the cell surface and for the activation of membrane fusion. SSP has b...

OBJECTIVE To evaluate the effects of tooth displacement and vibration on frictional force and stick-slip phenomenon (SSP) when conventional brackets were used with a levelling/alignment wire. MATERIALS AND METHODS The samples consisted of six groups (n = 10 per group) with combinations of tooth displacement (2mm lingual displacement [LD], 2mm gingival displacement [GD], and no displacement [c...
