Two experiments were conducted to evaluate the effects of feeding wet corn gluten feed (WCGF) on subacute acidosis in cattle. In Exp. 1, 60 individually fed yearling steers (270 +/- 22 kg BW) were used in a 5 x 2 factorial arrangement of treatments. Steers were assigned to one of five dietary treatments: 1) dry-rolled corn (DRC), 2) 35% WCGF fed d 1 to 132, 3) 86.5% WCGF fed d 1 reduced to 35% ...

Although lung cancer is the paradigm of a tobacco-induced malignancy, host-specific factors modulate susceptibility to tobacco carcinogenesis. Variations in DNA repair may influence the rate of removal of DNA damage and of fixation of mutations. To test the hypothesis that genetically determined DNA repair capacity (DRC) modulates lung cancer susceptibility, we conducted a pilot case-control st...

INTRODUCTION The last wild poliovirus (WPV) case in Africa was reported in July 2014, thus underscoring the tremendous progress towards polio eradication worldwide. This study aimed to analyze the results of a seven-year surveillance of Acute Flaccid Paralysis (AFP) in the Democratic Republic of Congo (DRC) and to identify potential gaps that need to be addressed. METHODS Epidemiological and ...

When two speech signals are mixed in a single channel the voiced parts of any of them remain mostly unaltered during the voicing interruptions of the other, i.e. pauses and voiceless consonants. The mixture is made of 3 types of multivoiced segments noted 0V (unvoiced), 1V (one voicing) and 2V (two voicings). A statistical study of readaloud texts reveals that total time spent in the 1V state i...

We address the problem of reconstructing a non-duplicated ancestor to a partially duplicated genome in a model where duplicated content is caused by several tandem duplications throughout its evolution and the only allowed rearrangement operations are DCJ. As a starting point, we consider a variant of the Genome Halving Problem, aiming at reconstructing a tandem duplicated genome instead of the...

General results on transformations on information production processes (IPPs), involving transformations of the h-index and related indices, are applied in concrete, simple cases: doubling the production per source, doubling the number of sources, doubling the number of sources but halving their production, halving the number of sources but doubling their production (fusion of sources) and, fin...

In this paper we study underlying graphs corresponding to a set of halving lines. We establish many properties of such graphs. In addition, we tighten the upper bound for the number of halving lines.
