Objective: We aimed to perform a meta-analysis from eligible studies to analyze the true impact of QL when compared with BL with regard to post-procedural outcomes including lead deactivation, revision or replacement. Background: Many observational and retrospective studies showed that quadripolar left ventricular leads (QL) are associated with better outcomes and fewer complications when compa...

Quality of Life (QL) is hard to assess and seldom measured in patients having carcinomas with an unfavourable prognosis. Oesophageal cancer is one of the malignancies with a low 5-year survival rate. Dysphagia (problems in swallowing food) is considered to be the most important indicator of QL in patients with oesophageal carcinoma. Moreover, the psycho-social aspects and subjective QL in cance...

In this paper, two Q-learning (QL) methods are proposed and their convergence theories are established for addressing the model-free optimal control problem of general nonlinear continuous-time systems. By introducing the Q-function for continuous-time systems, policy iteration based QL (PIQL) and value iteration based QL (VIQL) algorithms are proposed for learning the optimal control policy fr...

The current paper presents a novel approach to implement a graph transformation engine as an EJB3-specific plugin by using EJB QL queries for pattern matching. The essence of the approach is to create an EJB QL query for the precondition of each graph transformation rule. Pattern matching and updating phases of a rule application are implemented in a public method of a stateless session bean by...

Background Eosinophilic esophagitis (EoE) is a chronic, immunemediated disease of eosinophil-predominant inflammation and esophageal dysfunction. The Pediatric Quality of Life Inventory 3.0 EoE Module is a validated instrument to measure quality of life (QL) in children ages 2-18 with EoE, but no clinical research studies have been published using this survey. The objectives of this study were ...

We studied the relationship between pulmonary microvasculature fluid filtration pressures and lung lymph flow rate (QL) as filtration pressures increased to determine why lungs with functional lymphatics become edematous and, as filtration pressures decreased, to determine the effect of edema formation on lymphatic function. Edema was induced by rapid intravenous infusion of neutralized Ringer'...

Ventilation (V) increases lung lymph flow (Ql), but the separate effects of tidal volume (Vt) and frequency (f) and the role of V-induced changes in edema formation are poorly understood. An isolated, in situ sheep lung preparation was used to examine these effects. In eight sheep with f = 10 min(-1), results obtained during 30-min periods with Vt = 5 or 20 ml/kg were compared with values obtai...

We prove the Mumford-Tate conjecture for absolutely simple abelian fourfolds with trivial endomorphism algebras. The main goal of this paper is to prove the Mumford-Tate conjecture for certain abelian fourfolds. Let A/F be an abelian variety defined over a number field F of dimension n. Fix an algebraic closure F̄ of F and a complex embedding F̄ → C. Let V = H1(A/C,Q) be the first singular homolo...

Cardiac microvascular endothelial cells (CMECs) are important angiogenic components and are injured rapidly after cardiac ischaemia and anoxia. Cardioprotective effects of Qiliqiangxin (QL), a traditional Chinese medicine, have been displayed recently. This study aims to investigate whether QL could protect CMECs against anoxic injury and to explore related signalling mechanisms. CMECs were suc...
