Earlier a three-dimensional model for a new unusual DNA conformation referred to as Slipped Loop Structure (SLS) has been suggested by us (1). The same type of folding could occur with RNA as well which means that one must use the A-form of the double helix rather than the B-one. The present paper discusses the creation of an all-atom stereochemically sound model for SLS-RNA. This calculated mo...
Combined exposure to different irritants in the workplace may lead to irritant contact dermatitis, which is the main type of occupational dermatitis among bakers and confectioners. Following previous work on "tandem irritation", a panel of healthy volunteers was exposed twice daily for 4 days to the organic fruit acids: citric, malic, and lactic acid, either alone or in tandem application with ...
BACKGROUND AND PURPOSE There are no published studies on the parameterisation and reliability of the single-leg stance (SLS) test with inertial sensors in stroke patients. Purpose: to analyse the reliability (intra-observer/inter-observer) and sensitivity of inertial sensors used for the SLS test in stroke patients. Secondary objective: to compare the records of the two inertial sensors (trunk ...
BACKGROUND To assess the efficacy of adjuvant sclerotherapy after banding for the treatment of esophageal varices, a randomized trial was carried out of endoscopic variceal ligation (EVL) alone with sequential sclerotherapy versus sequential ligation-sclerotherapy (SLS) after banding with respect to variceal eradication, associated complications, and recurrence of varices. METHODS One hundred...
ESPRIT-type (spatial) frequency estimation techniques obtain their frequency estimates from the solution of a highly structured, overdetermined system of equations (the so-called invariance equation). Here, the structure is defined in terms of two selection matrices applied to a matrix spanning the estimated signal subspace. Structured least squares (SLS) is a new algorithm that solves the inva...
Shortest link scheduling (SLS) is one of the most fundamental problems in wireless networks. Almost all of the state-of-the-art approximation algorithms for SLS in wireless networks are resorted to the ellipsoid method for linear programming exclusively. However, the ellipsoid method can require an inordinate amount of running time and memory even for a moderate sized input, and consequently is...
State of the art Stochastic Local Search (SLS) solvers have difficulty in solving many CNF-encoded realistic SAT problems, apparently because they are unable to exploit hidden structure as well as systematic solvers. Recent work has shown that SLS solvers may benefit from a preprocessing phase borrowed from systematic SAT solving. In this paper, we report an extensive empirical examination of t...
Selective laser sintering (SLS) process has the potential to become one of the most useful additive manufacturing techniques in coming few years, because it has potential to easily produced complex shapes. Use of this process becomes more extensive, with the main advantages being a wide range of build materials available. So SLS can accommodate multiple applications throughout the manufacture p...
[Purpose] The purpose of the present study was to analyze the correlations of the thicknesses of the transversus abdominis muscle (Tra) and the internal obliquus abdominis muscle (Io) with static lumbar stability (SLS), dynamic lumbar stability (DLS), and balance. [Subjects] The subjects of the present study were 40 female university students who had no physical defects or pain. [Methods] The t...
While stochastic local search (SLS) techniques are very efficient in solving hard randomly generated propositional satisfiability (SAT) problem instances, a major challenge is to improve SLS on structured problems. Motivated by heuristics applied in complete circuit-level SAT solvers in electronic design automation, we develop novel SLS techniques by harnessing the concept of justification fron...
