In orbifold vacua containing an $S^q/\Gamma$ factor, we compute the relative order of scale separation, $r$, defined as ratio eigenvalue lowest-lying $\Gamma$-invariant state scalar Laplacian on $S^q$, to state. For $q=2$ and $\Gamma$ finite subgroup $SO(3)$, or $q=5$ $SU(3)$, maximal separation that can be achieved is $r=21$ $r=12$, respectively. smooth $S^5$ orbifolds, $r=4.2$. Methods from i...

Does the implementation of a share repurchase strategy create long-run firm value? Do companies initiating a strategy of repurchasing shares outperform companies not implementing this strategy? These two questions provide the foundation for this empirical study. An objective of the study is to use Tobin's Q ratio to determine if there is a change in the pre and post performance of companies wit...

Time reversal processes have been used to improve communication performance in the severe underwater communication environment characterized by significant multipath channels by reducing inter-symbol interference and increasing signal-to-noise ratio. In general, the performance of the time reversal is strongly related to the behavior of the q-function, which is estimated by a sum of the autocor...

An optimized three-lead ECG hierarchial decision-tree type of classification system for myocardial infarction is presented. For selection of the best threshold values for each criterion and the best association of features, we developed a procedure based on "receiver operating characteristic" (ROC) curve data analysis and information theory. Optimization was obtained through maximization of inf...

We have surveyed the 0.1–10 MeV nucleon 1 abundances of heavy ions from He through Fe in 64 large solar energetic particle (LSEP) events observed on board theAdvancedComposition Explorer from1997November through 2005 January. Our main results are (1) the 0.5–2.0MeV nucleon 1 He/He ratio is enhanced between factors of 2– 150 over the solar wind value in 29 ( 46%) events. (2) The Fe/O ratio in mo...

Fatty acids (FAs) have been postulated to impact adiposity, but few epidemiological studies addressing this hypothesis have been conducted. This study investigated the association between serum phospholipid FAs (S-PLFAs) and indicators of obesity. BMI and waist-to-hip ratio (WHR) were collected from 372 healthy Mexican women included as controls in a case-control study. S-PLFA percentages were ...

The strength ratio between hamstrings and quadriceps (H/Q) is associated with knee injuries as well as hip abductor muscle (HAB) weakness. Sixteen resistance trained men (age, 32.5 ± 4.2 years) performed 5 s maximal isometric contractions at 75° of knee flexion/extension and 15° of hip abduction on a dynamometer. After this isometric test they performed a Farmer's walk exercise to find out if t...

The recently discovered Gaia BH1 binary system, a Sun-like star and dark object (presumably black hole), may significantly change our understanding of the population binaries. paper presents components mass ratio (q) distributions systems different observational classes. They all show significant shortage low-q systems. In this work, I demonstrate (quantitatively) how ignorance extends, point o...

[Purpose] The purpose of this study was to elucidate the relationship between knee muscle strength and knee pain in activities of daily living, based on consideration of the difference between extension and flexion strength (Q - H) and the hamstring:quadriceps (H:Q) ratio in patients with knee osteoarthritis. [Subjects and Methods] The participants were 78 females with knee osteoarthritis, and ...

The machine covering problem deals with partitioning a sequence of jobs among a set of machines, so as to maximize the completion time of the least loaded machine. We study a semi-online variant, where jobs arrive one by one, sorted by non-increasing size. The jobs are to be processed by two uniformly related machines, with a speed ratio of q ≥ 1. Each job has to be processed continuously, in a...
