We give a basis for the space spanned by the sum ŝλ of the lowest degree terms in the expansion of the Schur symmetric functions sλ in terms of the power sum symmetric functions pμ, where deg(pi) = 1. These lowest degree terms correspond to minimal border strip tableaux of λ. The dimension of the space spanned by ŝλ, where λ is a partition of n, is equal to the number of partitions of n into pa...

We propose a bottom-up variant of Earley deduction. Bottom-up deduction is preferable to top-down deduction because it allows incrementai processing (even for head-driven grammars), it is data-driven, no subsumption check is needed, and preference values attached to lexical items can be used to guide best-first search. We discuss the scanning step for bottom-up Earley deduction and indexing sch...

CLINICAL BOTTOM LINE Water intake is a cost effective, non-invasive and low-risk intervention to reduce or prevent headache pain. RATIONALE Chronic mild dehydration may trigger headache. Increased water intake could help. A small trial shows modest benefit; however, a larger methodologically sound randomized controlled trial is needed to confirm efficacy. CRITICALLY APPRAISED PAPER Spigt, M...

Thirty five subjects with both parents in the top third of their age specific blood pressure distributions and 31 subjects with both parents in the bottom third of their blood pressure distributions restricted their intake of sodium for eight weeks while taking part in a double blind, randomised crossover trial of supplements of sodium and placebo. A comparison of two periods of four weeks at d...

“Very small but cumulated decreases in food intake may be sufficient to have significant effects, even erasing obesity over a period of years” (Rozin et al., 2011). In two studies, one a lab study and the other a real-world study, we examine the effect of manipulating the position of different foods on a restaurant menu. Items placed at the beginning or the end of the list of their category opt...

OBJECTIVE To determine the association between 25-hydroxyvitamin D (25-OHD) concentration and risk of incident type 2 diabetes. RESEARCH DESIGN AND METHODS In a nested case-control study conducted among 608 women with newly diagnosed type 2 diabetes and 559 control subjects in the Nurses' Health Study, we measured the association between baseline plasma 25-OHD concentration and risk of incide...

Colonies of the octocoral Alcyonium siderium Verrill form aggregations on subtidal vertical rock walls in the Gulf of Maine. Maximum and mean colony sizes increase dramatically from protected embayments to sites exposed to ocean swells and from the bottom to the top of each vertical wall studied. Water movement along the substratum, generated by surface waves and tides, also increases along bot...

organochlorine and organophosphate pesticides are likely to pollute lipid-containing food sources, like milk (3-5% fat), owing to their lipophilicity, thereby jeopardizing the benefits of milk as a health food. pesticide load in bovine milk may be from the leaching of pesticides persisting in the adipose tissue of the animal, or through direct contamination during milking or improper handling o...

nutritional status during adolescence plays an important role in human lifecycle. the aim of this study was nutritional status and dietary intake among adolescent girls. in a cross sectional study, using two stage cluster sampling 256 adolescent girls were randomly selected from 8 semnan secondary schools. weight and height were measured and body mass index (bmi) was calculated. in adolescents,...
