We read with interest the article recently published in the September issue of the Asian Journal of Sports Medicine by Loenneke et al. We were particularly interested in the section that stated; ‘The BIA device investigated in this study did not provide a valid estimate of fat free mass index (FFMI) in male and female collegiate athletes. Although there was a general tendency for the bioelectri...

The most common method of ascertaining cloud heights from space is from thermal brightness temperatures. Deep convective clouds of high water content are expected to radiate as black bodies. Here, thermal cloud top estimates from GOES-8 are compared with direct estimates of where the top should be sensed, based on colocated Goddard Cloud Physics Lidar (CPL) observations collected during the Cir...

BACKGROUND Adolescence is a time of rapid growth with dramatic changes in physical appearance. The body image established at this time could affect their physical and mental health throughout their entire life. However, adolescents sometimes perceive themselves as underweight or overweight irrespective of actual weight status. The purpose of the present study was to examine the extent of weight...

Distance perception in virtual reality is reviewed, and investigated in a series of experiments. In experiment 1, the systematic underestimation of distance found in virtual reality displays was investigated. This investigation used a video camera mounted on a head-mounted display to compare a photorealistic ”virtual” world to monocular viewing of the real world with restricted field of view an...

Purpose PET/CT is useful in preoperative evaluation of invasive breast cancer (IBC) to predict axillary metastasis and staging workup. The usefulness is unclear in cases of ductal carcinoma in situ (DCIS) diagnosed at biopsy before surgery, which sometimes is upgraded to IBC after definitive surgery. The aim of this study is to find out the usefulness of PET/CT on DCIS as a preoperative evaluat...

BACKGROUND Several studies have found participants pour more than 1 standard drink or unit as their usual glass. This is the first study to measure actual and perceived amounts of alcohol in a self-defined usual glass of wines and spirits in the general population. METHODS Participants were a convenience sample of adults who drink alcohol or who pour drinks for other people (n = 283, 54% wome...

PURPOSE To determine the influence of the spatial extent and the depth of localized field loss on the computation of the General Height (GH) method for estimating the diffuse component of visual field loss and, therefore, on the subsequent appearance of the Pattern Deviation (PD) map. METHODS Varying shapes and depths of localized glaucomatous field loss were modeled in each of 82 Humphrey Fi...

PURPOSE A previously published cardiac-gated 2D Qflow protocol at 7 T in cerebral perforating arteries was optimized to reduce velocity underestimation and improve temporal resolution. METHODS First, the signal-to-noise ratio (SNR) gain of the velocity measurement (SNRv ) was tested for two signal averages versus one. Second, the decrease in velocity underestimation with a tilted optimized no...

PURPOSE To explore: 1) parent-adolescent discrepancies on adolescent risk involvement; 2) factors related to parental overestimates and/or underestimates of specific adolescent risk behaviors; and 3) the association of parental overestimates and/or underestimates at baseline with subsequent adolescent risk involvement. METHODS 754 African American parent-adolescent dyads were recruited from 3...

This paper examines why a financial entity’s solvency capital estimation might be underestimated if the total amount required is obtained directly from a risk measurement. Using Monte Carlo simulation we show that, in some instances, a common risk measure such as Value-at-Risk is not subadditive when certain dependence structures are considered. Higher risk evaluations are obtained for independ...
