This paper studies the dynamic bin packing problem, in which items arrive and depart at arbitrary time. We want to pack a sequence of unit fractions items (i.e., items with sizes 1/w for some integer w ≥ 1) into unit-size bins such that the maximum number of bins used over all time is minimized. Tight and almost-tight performance bounds are found for the family of any-fit algorithms, including ...

The effects of the introduction of an 8-h asynchrony between ovulation and insemination on litter size components from rabbits were assessed. A total of 202 females belonging to a maternal line were used. Fresh and frozen sperm were used to perform the inseminations. Sperm was frozen with an extender composed of 1.75 M DMSO and 0.05 M sucrose. Four experimental groups were obtained depending on...

Gaussian-PLDA (G-PLDA) modeling for i-vector based speaker verification has proven to be competitive versus heavytailed PLDA (HT-PLDA) based on Student’s t-distribution, when the latter is much more computationally expensive. However, its results are achieved using a length-normalization, which projects i-vectors on the non-linear and finite surface of a hypersphere. This paper investigates the...

In 3 experiments, the authors investigated how strategic inclinations associated with promotion versus prevention orientations--that is, eager approach versus vigilant avoidance, respectively--affect the use of language. It is hypothesized that eager promotion strategies used to attain desired end states entail using more abstract language than used with vigilant prevention strategies. This is ...

background: early diagnosis of abnormal progressive labor and prevention of prolonged labor will cause decreased complications of mothers and fetuses. this was conduced to evaluate the alert line in who recommended program for diagnosis of abnormal labor. methods: subjects were 140 pregnant women. when their cervices were dilated about 3cm, the progress of delivery and condition of mothers and ...

In ventricular cardiac myocytes, T-tubule density is an important determinant of the synchrony of sarcoplasmic reticulum (SR) Ca release and could be involved in the reduced SR Ca release in ischemic cardiomyopathy. We therefore investigated T-tubule density and properties of SR Ca release in pigs, 6 weeks after inducing severe stenosis of the circumflex coronary artery (91 3%, N 13) with myoca...

In ventricular cardiac myocytes, T-tubule density is an important determinant of the synchrony of sarcoplasmic reticulum (SR) Ca2+ release and could be involved in the reduced SR Ca2+ release in ischemic cardiomyopathy. We therefore investigated T-tubule density and properties of SR Ca2+ release in pigs, 6 weeks after inducing severe stenosis of the circumflex coronary artery (91+/-3%, N=13) wi...

Several polymorphisms in the vitamin D receptor (VDR) gene have been implicated as risk factors for prostate cancer. We performed a meta-analysis of 14 studies (17 comparisons) with TaqI genotyping (1870 prostate cancer cases; 2843 controls), 6 studies (8 comparisons) with poly(A) repeat genotyping (540 cases; 870 controls), 5 studies with BsmI genotyping (987 cases; 1504 controls), and 3 studi...
