STUDY DESIGN Cross-sectional controlled laboratory study. OBJECTIVES To investigate potential changes in the function of discrete regions of the psoas major (PM) and quadratus lumborum (QL) with changes in spinal curvatures and hip positions in sitting, in people with recurrent low back pain (LBP). BACKGROUND Although the PM and QL contribute to control of spinal curvature in sitting, wheth...

BACKGROUND The purpose of this study was to evaluate the individualized and standardized quality of life (QL) and psychological distress of patients participating in a Phase I trial of the novel therapeutic reovirus (Reolysin). METHODS 16 patients with incurable metastatic cancer were interviewed prior to being accepted into the phase I trial with a semi-structured expectations interview, the...

Zonostrophic instability leads to the spontaneous emergence of zonal jets on a β-plane from a jetless basic-state flow which is damped by bottom drag and driven by a random body force. Decomposing the barotropic vorticity equation into the zonal-mean and eddy equations, and neglecting the eddyeddy interactions, defines the quasi-linear (QL) system. Numerical solution of the QL system shows zona...

The quality of life (QL) concept has led to extensive scientific research and has been increasingly used by health care professionals treating a wide range of diseases. This paper addresses the historical use of the concept and specific issues linked to conceptual and methodological aspects of the QL construct within the health care context. Reviewing the literature, two aspects stand out: subj...

Quantum lithography (QL) is a revolutionary approach, increasing the throughput and lowering the cost of scanning electron beam lithography (EBL). But it has not been pursued since its inception 17 years ago, due to the lack of a viable method for making the blanks needed. Here we propose and demonstrate a new general viable approach to QL blank fabrication, that is based on (a) nanoimprinting ...

This paper describes QL, a language for querying complex, potentially recursive data structures. QL compiles to Datalog and runs on a standard relational database, yet it provides familiar-looking object-oriented features such as classes and methods, reinterpreted in logical terms: classes are logical properties describing sets of values, subclassing is implication, and virtual calls are dispat...

This paper deals with a kind of implications defined from t-norms, t-conorms and strong negations on a finite chain, through the expression I(x,y) = S(N(x),T (x,y)), and called QL-implications. We mainly study those QL-implications derived from smooth t-norms and t-conorms. It is characterized when functions defined in this way are implication functions, and their analytical expression is given...

The effects of substituents on the pKas of a set of 16 substituted benzoic acids have been examined using density functional theory [B3LYP/6-311G(d, p)] calculations. A variety of quantum chemical parameters were examined as indicators for the variations observed in the experimental pKas, including the Löwdin, Mulliken, AIM, and natural population analysis charges (QL, QM, QA, and Qn) on atoms ...

BACKGROUND Tobacco dependence is a chronic, relapsing condition that typically requires multiple quit attempts and extended treatment. When offered the opportunity, relapsed smokers are interested in recycling back into treatment for a new, assisted quit attempt. This manuscript presents the results of a randomized controlled trial testing the efficacy of interactive voice response (IVR) in rec...
