The performance and hardware complexity of superscalar architectures is hindered by conditional branch instructions. When conditional branches are encountered in a program, the instruction fetch unit must rapidly predict the branch predicate and begin speculatively fetching instructions with no loss of instruction throughput. Speculative execution increases hardware cost, since speculative inst...

BACKGROUND Pedicled periosteal flaps are commonly used for tissue defects between the base of the skull and the midfacial area. This study aimed to clarify the 3-dimensional vascular distribution of temporal region flaps. METHODS Ten fresh cadavers were used. Full-thickness cranial flaps were elevated from the cranial bone and each layer was detached separately. Contrast enhancement of the fu...

The tomato (Lycopersicon spp.) productivity is severely reduced by attack of several insects and microorganisms. It is economically one of the most important crops that has been extensively cultivated in the Americas. Therefore, assays were performed in the greenhouse and the laboratory to evaluate the possible interaction between resistant tomato genotypes and plant extracts on the control of ...

The purpose of this study was to estimate the distance from the mandibular marginal branch of the facial nerve to the inferior margin of the mandible in order to determine the best and safest location to approach the posterior mandibular region. Forty-five hemi-faces of 27 Brazilian adult cadavers were dissected and the distance between the mandibular marginal branch and the inferior margin of ...

While many researchers devoted numerous articles to the organizational culture, relatively few articles have been contributed to culture and performance research. The purpose of this study is to shed light on the role of organizational culture on performance. To achieve this goal and in order to measure organizational culture, Denison organizational culture model was used. The components of thi...

Program specialization is a program transformation methodology which improves program efficiency by exploiting the information about the input data which are available at compile time. We show that current techniques for program specialization based on partial evaluation do not perform well on nondeterministic logic programs. We then consider a set of transformation rules which extend the ones ...

BACKGROUND Arterial hypertension is the commonest cause of cardiovascular death. It may lead to hypertensive heart disease (HHD), including heart failure (HF), ischemic heart disease (IHD) and left ventricular hypertrophy (LVH). MAIN BODY According to the 2007 ESH/ESC guidelines, the recommended imaging technique is echocardiography (echo), when a more sensitive detection of LVH than that pro...
