OBJECTIVE Evaluate the effectiveness of distance physical activity interventions to establish intervention features that are key to success. DATA SOURCE Computerized searches for randomized controlled trials (RCTs) of distance physical activity interventions and visual scans of reference lists were performed between March 2004 and July 2006. STUDY INCLUSION AND EXCLUSION CRITERIA Studies we...
We prove the Doran–Harder–Thompson conjecture in the case of elliptic curves by using ideas from SYZ mirror symmetry. The conjecture claims that when a Calabi– Yau manifold X degenerates to a union of two quasi-Fano manifolds (Tyurin degeneration), a mirror Calabi–Yau manifold of X can be constructed by gluing the two mirror Landau– Ginzburg models of the quasi-Fano manifolds. The two crucial i...
The development of manual-based psychological treatments for a wide range of clinical disorders has had a significant impact not only on clinical research, but also on clinical practice. Theory-driven, manual-based treatments have become a defining feature of evidence-based treatments for specific clinical disorders that have been evaluated in numerous randomized controlled trials (RCTs). The a...
The notions of prime(semiprime) fuzzy h-ideal(h-biideal, h-quasi-ideal) in Γ-hemiring are introduced and some of their characterizations are obtained by using ”belongingness(∈)” and ”quasi − coincidence(q)”. Cartesian product of prime(semiprime) fuzzy h-ideals of Γ-hemirings are also investigated. Keywords—Γ-hemiring, Fuzzy h-ideals, Prime fuzzy left h-ideal, Prime(semiprime) (∈,∈ ∨q)-fuzzy lef...
The aim of this systematic review was to estimate the efficiency of hypnosis prior to medical procedures. Different databases were analyzed to identify randomized controlled trials (RCTs) comparing hypnosis to control interventions. All RCTs had to report pain or anxiety. Eighteen RCTs with a total of 968 patients were included; study size was from 20 to 200 patients (14 RCTs ≤ 60 patients). Fo...
BACKGROUND AND OVERVIEW Dental practitioners spend most of their time administering treatments. To ensure that their clinical decisions are informed by the best available evidence, dental practitioners need to be skilled in critically appraising studies addressing therapy issues. Randomized controlled trials offer the optimal study design to inform decisions regarding therapy. The critical appr...
Recruitment and retention of participants in randomized controlled trials (RCTs) drawn from the older population is challenging, and studies have shown that poor recruitment and retention may lead to biased samples and results. Several strategies to improve the participation of older adults in research are outlined in the literature. The objective was to identify factors associated with partici...
A novel strategy of discrete energy consumption model for WSN based on quasi Monte Carlo and crude Monte Carlo method is developed. In our model the discrete hidden Markov process plays a major role in analyzing the node location in heterogeneous media. In this energy consumption model we use both static and dynamic sensor nodes to monitor the optimized energy of all sensor nodes in which every...

I describe the findings of one of the largest randomized controlled trials (RCTs) of rehabilitation after traumatic brain injury (TBI) ever conducted, examine the theoretical relationship between cognitive and functional rehabilitation after TBI, and describe the historical preference for cognitive (top-down) rather than functional (bottom-up) interventions. I also contrast the goals and princi...
