In this paper, we use signed bipartite graphs to model opinions expressed by one type of entities (e.g., individuals, organizations) about another (e.g., political issues, religious beliefs), and based on the strength of that opinion, partition both types of entities into two clusters. The clustering is done in such a way that support for the second type of(More)
Modern software systems often consist of many different components, each with a number of options. Although unit tests may reveal faulty options for individual components, functionally correct components may interact in unforeseen ways to cause a fault. Covering arrays are used to test for interactions among components systematically. A two-stage framework,(More)
The toxic effect of Bisphenol A (BPA) on heart ventricular function has not been reported till date. So the present study was undertaken to examine the effect of BPA on ventricular function in rat models. BPA (50mg/kgBW/day) was administered for 20 and 30 days by oral-gavage. The rats were sacrificed by cervical dislocation on 24 th hour after last(More)
An antibody format, termed Fab-dsFv, has been designed for clinical indications that require monovalent target binding in the absence of direct Fc receptor (FcR) binding while retaining substantial serum presence. The variable fragment (Fv) domain of a humanized albumin-binding antibody was fused to the C-termini of Fab constant domains, such that the VL(More)
We identify influential early adopters that achieve a target behavior distribution for a resource constrained social network with multiple costly behaviors. This problem is important for applications ranging from collective behavior change to corporate viral marketing campaigns. In this paper, we propose a model of diffusion of multiple behaviors when(More)
CONTEXT Anemia is a major contributor to morbidity and mortality among women of reproductive age. Progress toward reducing the burden of anemia has been little despite efforts through decades. AIMS We conducted this study to unearth the microlevel determinants of anemia among women of reproductive age. SETTINGS AND DESIGN This qualitative study was(More)
A covering array CA(N ; t, k, v) is an N × k array with entries in {1, t among its rows. Covering arrays find application in interaction testing, including software and hardware testing, advanced materials development, and biological systems. A central question is to determine or bound CAN(t, k, v), the minimum number N of rows of a CA(N ; t, k, v). The(More)
Ureteral tumors are rare and benign tumors are even rarer. Most of such tumors are diagnosed after nephroureterectomy assuming a malignant lesion, but with modern technological advancements like contrast enhanced CT scan or MR urography and ureteroscopic biopsy, benign nature of such tumors can be established preoperatively with an aim to preserve the renal(More)
