Eastern boundary currents are often described as 'wasp-waist' ecosystems in which one or few mid-level forage species support a high diversity of larger predators that are highly susceptible to fluctuations in prey biomass. The assumption of wasp-waist control has not been empirically tested in all such ecosystems. This study used stable isotope analysis to test the hypothesis of wasp-waist con...

In this paper, we summarize a remarkable result obtained by Soskin et al. in Phys Rev A 56, 4064 (1997). We show that for an on-axis superposition of two different-waist Laguerre-Gauss beams with numbers (0, n) and m), the topological charge equals TC=m up to plane where waist radii become same, given beam m) has greater radius, changing TC=n after plane. This occurs because initial op-tical vo...

The waist inequality is a fundamental fact of Euclidean geometry. It’s also a difficult theorem it’s much harder to prove than it may look at first sight. In my opinion, the waist inequality is one of the most underappreciated theorems in geometry, and so I am excited to write about it. The waist inequality also connects with several other areas of mathematics. Gromov began writing about the wa...

OBJECTIVE To measure neck circumference and waist circumference, to compare it between normal and overweight/obese adolescents, and to validate these with body mass index. METHODS This cross-sectional study was conducted in 1800 school-going adolescents. Body mass index, waist circumference and neck circumference were measured. Independent samples t-test and Pearson's correlation were used as...

OBJECTIVE To study anthropometrical and body composition variables as predictors of risk for metabolic alterations and metabolic syndrome in female adolescents. METHODS Biochemical, clinical and corporal composition data of 100 adolescents from 14 to 17 years old, who attended public schools in Viçosa, Southeastern Brazil, were collected. RESULTS Regarding nutritional status, 83, 11 and 6% ...

Several published studies have reported the need to change the cutoff points of anthropometric indices for obesity. We therefore conducted a cross-sectional study to estimate anthropometric cutoff points predicting high coronary heart disease (CHD) risk in Korean adults. We analyzed the Korean National Health and Nutrition Examination Survey data from 2007 to 2010. A total of 21,399 subjects ag...

Previous research has indicated that men generally rate slimmer women as more sexually attractive, consistent with the increased morbidity risks associated with even mild abdominal adiposity. To assess the association of women's waist size with a more tangible measure of perceived sexual attractiveness (as well as reward value for both sexes), we examined the association of women's age and wais...

OBJECTIVE The purpose of our study was to determine which measure of obesity is better at predicting cardiovascular risk in African Americans. We hypothesized that BMI alone would be significantly associated with cardiovascular reactivity. We also hypothesized that waist circumference alone would be significantly associated with cardiovascular reactivity. Lastly, we hypothesized that BMI and wa...

Cardiovascular disease (CVD) is one of the non-communicable diseases which mayor leading cause death in world. One modifiable factors cardiovascular central obesity. Assessment obesity status was carried out by measuring waist circumference (WC) and waist-to-hip ratio (WHR). This study aimed to determine relationship between WC WHR with risk disease. an observational a cross-sectional design. T...

Results: Mean age of participants was 74.96 ± 5.603 years. Mean waist circumference in whole sample measured 96.78 ± 16.85, mean hip circumference was 106.31 ± 19.24, mean waist hip ratio measured 0.91 ± 0.09 and mean body mass index was 27.83 ± 9.8. All of waist circumference, waist hip ratio, systolic blood pressure, hypertension, diabetes mellitus, ischemic heart disease, renal disease were ...
