LS 5039 is a high-mass gamma-ray binary hosting compact object of unknown type. NuSTAR observed during its entire 3.9 day period. We performed periodic signal search up to 1000 Hz which did not produce credible period candidates. do see the 9.05 s candidate, originally reported by Yoneda et al. 2020 using same data, in Fourier power spectrum, but we find that statistical significance this featu...
Fast-starts associated with escape responses were studied in short-horn sculpin (Myoxocephalus scorpius L.), ranging from 5.5 to 32 cm in total length (L). Electromyography and sonomicrometry were used simultaneously to measure muscle activation and length changes, respectively, in the superficial layers of fast muscle in rostral myotomes. Escape responses consisted of a half tailbeat to bend t...
Fin ray structure in ray-finned fishes (Actinopterygii) largely defines fin function. Fin rays convert the muscle activity at the base of the fin to shape changes throughout the external fin web. Despite their critical functional significance, very little is known about the relationship between form and function in this key vertebrate structure. In this study we demonstrate that morphological s...
Lovász and Schrijver [17] introduced several lift and project methods for 0-1 integer programs, now collectively known as Lovász-Schrijver (LS) hierarchies. Several lower bounds have since been proven for the rank of various linear programming relaxations in the LS and LS+ hierarchies. In this paper we investigate rank bounds in the more general LS∗ hierarchy, which allows lifts by any derived ...
Light sticks (LS) are sources of chemiluminescence commonly used in pelagic fishery, where hundreds are discarded and reach the shores. Residents from fishing villages report an improper use of LS contents on the skin. Given the scarce information regarding LS toxicity, the effects of LS solutions in cell cultures were evaluated herein. Loss of viability, cell cycle changes and DNA fragmentatio...
We investigated the widespread belief that life gets better and better over time—as revealed in individuals’ “subjective trajectories” for life satisfaction (LS) derived from their ratings of recollected past, current, and anticipated future LS— among depressed (i.e., current major depressive disorder, fully remitted, partially remitted) and nondepressed groups using a two-wave longitudinal sam...
BACKGROUND The aim of this study was to describe changes in repeated liver stiffness (LS) measurements and to assess the determinants of increase in LS in HIV-HCV-coinfected patients. METHODS HIV-HCV-coinfected adults enrolled in the ANRS CO 13 HEPAVIH cohort, for whom two results of LS, evaluated over ≥24 months, were available. Patients with unreliable LS results were not included. LS was m...
