We consider a known variant of bin packing called cardinality constrained packing, also with constraints (BPCC). In this problem, there is parameter k≥2, and items rational sizes in [0,1] are to be packed into bins, such that no has more than k or total size larger 1. The goal minimize the number bins. A recently introduced concept, price clustering, deals inputs presented way they split cluste...

Congenital cytomegalovirus (cCMV) infections cause more children to have permanent disabilities than Down Syndrome, Fetal Alcohol Syndrome, Spina Bifida, and pediatric HIV/AIDS combined. The risk of infection during pregnancy can be significantly decreased using universal precautions, such as thorough handwashing and cleansing of surfaces and objects that have come into contact with infected bo...

Ultrafiltration using polyethersulfone-membranes was evaluated as an efficient and preferred method for purifying Cowpea Chlorotic Mottle Virus (CCMV). Cesium chloride (CsCl) ultracentrifugation and ultrafiltration protocols are described, and comparative UV-spectroscopic and electron micrograph results are presented. CCMV purified by ultrafiltration are shown to be equivalent to CCMV purified ...

OBJECTIVE To determine the incidence, characteristics, and evolution of sensorineural hearing loss (SNHL) in infants with a congenital cytomegalovirus infection (cCMV). STUDY DESIGN In a prospective 10-year study, 14 021 unselected live-born infants were screened for cCMV by virus isolation in urine. Congenitally infected newborns were evaluated for SNHL during the first 5 years of life. RE...
