Standard radiation therapy for patients undergoing primary chemosensitized radiation for carcinomas of the cervix usually consists of external beam radiation followed by an intracavitary brachytherapy boost. On occasion, the brachytherapy boost cannot be performed due to unfavorable anatomy or because of coexisting medical conditions. We examined the safety and efficacy of using CyberKnife ster...

The symmetries of the topological Yang-Mills theory are studied in the Hamiltonian formalism and the generators of the twisted N=2 superPoincaré algebra are explicitly constructed. Noting that the twisted Lorentz generators do not generate the Lorentz symmetry of the theory, we relate the two by extracting from the latter the twisted version of the internal SU(2) generator. The hermiticity prop...

The influence of switching frequency on the low-frequency oscillation in the voltage-controlled buck-boost converter is studied in this paper. Firstly, the mathematical model of this system is derived. And then, a glimpse at the influence of switching frequency on the low-frequency oscillation in this system by MATLAB/Simulink is given. The improved averaged model of the system is established, ...

background: tibial avulsion fractures of the posterior cruciate ligament are not infrequent. however, controversies exist between the fixation of the fragments and their reconstruction in the cases with small bony fragments. this prospective study was undertaken to study the results after fixation of the fragments by the malleolar screw and the pull through suture techniques.   methods: from ju...

In this paper, we propose the post-classification scheme that is useful for improving weak-hypothesis combination of AdaBoost. The post-classification scheme allows the weak hypotheses to be combined nonlinearly, and can be shown to have a generally better performance than the original linear-combination approach in either theory or practice. The post-classification scheme provides a general pe...

In this study investigation is done on an H-bridge switched inductor base cascade multilevel DC-DC boost converter. The proposed multilevel DC-DC boost converter topology improves the conversion efficiency of traditional topology. The proposed boost converter topology is differing from the traditional topology by the addition of switched inductor circuit. The switched inductor improved the conv...

purpose: to determine the sensitivity and specificity of posterior corneal elevation in discriminating keratoconus and subclinical keratoconus from normal corneas by galilei and orbscan ii diagnosed on the basis of topography. methods: three groups (keratoconus, subclinical keratoconus and normal) were evaluated with galilei and orbscan ii and results were compared to those obtained by gold sta...

purpose: to compare the effect of implantation of a single-piece hydrophilic foldable acrylic intraocular lens (iol) with rectangular optic edge and a single-piece polymethyl methacrylate (pmma) iol with rounded optic edges on posterior capsular opacification )pco(. methods: this randomized clinical trial study comprised 74 eyes with senile cataract in an otherwise normal eye in patients older ...

the most common type of arrhythmia following coronary artery bypass graft (cabg) is atrial fibrillation (af) with an incidence rate of 20-30%. pericardial effusion is one of the etiologic factors of atrial fibrillation occurring after cabg. posterior pericardiotomy (pp) causes the drainage of blood and fluids from the pericardial space into the pleural space leading to a decreased pericardial e...

conclusion with thorough technical knowledge and an adequate learning curve, pra could serve as the surgeon’s preferred surgical approach to the adrenal gland within the confines of its selection criteria. background since the early 1990s, endoscopic adrenalectomy has become the gold standard surgical approach for the adrenal gland. also, lateral transperitoneal adrenalectomy (lta) which is the...
