This document describes the techniques used in and results of our project to apply social and information network analysis to the Kiva.org online microlending network. The Kiva network can be modeled as a set of bipartite graphs linking lenders to loans, lending teams to loans, and individual lenders to lending teams. Folding the lender-loan graph to create a graph of lenders linked by common l...

As larger macromolecular structures become available, there is a growing need to understand their 'internal' volumes--such as deep clefts, channels and cavities--as these often play critical roles in their function. The 3V web server can automatically extract and comprehensively analyze all the internal volumes from input RNA and protein structures. It rapidly finds internal volumes by taking t...

A rail-to-rail class-AB CMOS buffer is proposed in this paper to drive large capacitive loads. A new technique is used to reduce the leakage power of class-AB CMOS buffer circuits without affecting dynamic power dissipation .The name of applied technique is LECTOR, which gives the high speed buffer with the reduced low power dissipation (1.05%) and reduced area (2.8%). The proposed buffer is si...

Aim: Four viral pathogens, bovine viral diarrhea virus (BVDV), and bovine herpes virus type 1 (BHV-1), bovine parainfluenza type 3 virus (PI-3V), bovine respiratory syncytial virus (BRSV) are mainly associated with bovine respiratory diseases that cause major economic losses in the dairy cattle industry. This study aimed to document exposure of cattle in Saudi Arabia to infectious BVDV, BHV-1, ...

Leishmaniasis is a neglected tropical disease caused by protozoan parasites belonging to the genus Leishmania. Currently, the drugs available for treatment of this disease present high toxicity, along with development of parasite resistance. In order to overcome these problems, efforts have been made to search for new and more effective leishmanicidal drugs. The aim of this study was to synthes...

In the adult brain, leptin regulates energy homeostasis primarily via hypothalamic circuitry that affects food intake and energy expenditure. Evidence from rodent models has demonstrated that during early postnatal life, leptin is relatively ineffective in modulating these pathways, despite the high circulating levels and the presence of leptin receptors within the central nervous system. Furth...

This paper studies the gender gap in accessing financial resources through crowdfunding by developing a novel construct for social capital, latent network capital. We provide original empirical evidence based on 985 projects hosted Kiva, platform reaching 3.7 million borrowers, 81 % of them women, assessing how interplay between capital and project proposer affects amount funds raised. To this ...

Making semiconductor devices based on single-walled carbon nanotubes (SWCNT) is one of the more compelling potential applications of these long but ultrathin structures. We see asymmetric voltage-current behavior across a random network of SWCNTs contacted by asymmetric metal electrodes (Au/Al). No effort was made to align the SWCNTs or to eliminate metallic nanotubes in our devices, procedures...

An improved spark ignition model has been developed and implemented into the KIVA-3V code. In this model, the spark ignition kernel growth is tracked by Lagrangian particle markers. The effects of turbulent flow and spark discharge energy on the kernel growth are considered. After the ignition kernel size exceeds a critical size related to the integral turbulent length scale of the flow, the tu...
