Background and aims: Chronic kidney disease (CKD) is a public health challenge worldwide, with adverse consequences of kidney failure, cardiovascular disease (CVD), and premature death. Chronic kidney disease leads to the end stage of renal disease (ESRD), if late/not diagnosed. Competing risk modeling is a major issue in Epidemiology research. In Epidemiology study, sometimes inappropriate met...

aim : this study aims to investigate some clinical and pathologic factors associated with the prognosis of patients with colon and rectum cancers separately. background : colorectal cancer is the most common cancer of the digestive system and also the fourth cause of cancer-related deaths around the world. different studies indicate that survival of patients with colorectal cancer has improved ...

We study the role of the noise in the dynamics of two competing species. We consider generalized Lotka-Volterra equations in the presence of a multiplicative noise, which models the interaction between the species and the environment. The interaction parameter between the species is a random process which obeys a stochastic differential equation with a generalized bistable potential in the pres...

The rodent hippocampus represents different spatial environments distinctly via changes in the pattern of "place cell" firing. It remains unclear, though, how spatial remapping in rodents relates more generally to human memory. Here participants retrieved four virtual reality environments with repeating or novel landmarks and configurations during high-resolution functional magnetic resonance i...

This paper develops a pricing and inventory model of a supply chain composing one supplier and two manufacturers in which the supplier sells its product to two competing manufacturers. Each manufacturer faces a deterministic demand that depends on his/her own and the other competitor sale price. Selling price for the supplier is time dependent and increment function.Both amelioration and deteri...

Title of Document: RELIABILITY AND TEST ENVIRONMENT OF THE SCAN-A WITH CHILDREN AGES 12-15 Michele Lynn Spencer, Doctor of Clinical Audiology, 2007 Directed By: Professor Sandra Gordon-Salant, Hearing and Speech Sciences The SCAN-A is a widely utilized auditory processing screening tool for use with adolescents and adults 12-to-50 years of age. The SCAN-A consists of four subtests: Filtered Wor...

In this study, a general model of interacting species consisting two competing prey and predator under the presence pollution is formed. Criteria for existence equilibria their (local global) stability are derived. The conditions persistence bifurcation have also been With help numerical simulation, it shown how change in level results extinction.

This paper considers the parcel hub scheduling problem (PHSP) with unequal batch size inbound trailers, which is a combinatorial optimization problem commonly found in a parcel consolidation terminal in the parcel delivery industry (PDI). The problem consists of processing a large number of inbound trailers at a much smaller number of unload docks. The parcels in the inbound trailers must be un...
