INTRODUCTION: Degenerative lumbar spine surgery is increasingly common, but osteoporosis and the need for long-segment fixation negatively impact implant stability. In our study, we investigated the effect of osteoporosi...

ABSTRACT Objective Subtrochanteric shortening osteotomy (SSO) with autogenous cortical plate grafting is a critical but technically demanding procedure in total hip arthroplasty for Crowe type IV developmental dysplasia ...

Objective: To compare the amount of debris extruded apically between various root canal instrumentation techniques. Material and Methods: 60 extracted human premolars were randomly divided into 4 groups (n= 15). The firs...

Introduction We developed an innovative, active learning workshop to introduce foundations of point-of-care ultrasound (POCUS) physics and instrumentation. The workshop design aimed to reduce cognitive load and encourage...

Abstract Background Ambulatory wireless video electroencephalography (AEEG) is the method of choice to discriminate epileptic seizures from other nonepileptic episodes. However, the influence of prior general anesthesia ...

Abstract A selective and eco-friendly spectrophotometric approach was developed for the quantitative determination of entacapone (ENT) in the presence of its co-formulated drugs carbidopa (CAR) and levodopa (LEV) which e...

An overview of near-field optics is presented with a focus on the fundamental advances that have been made in the field since its inception 30 years ago. A focus is placed on the advancements that have been achieved in i...

Sparse systems of equations are an essential part of real mod- els, being decisive in simulation or optimization. By increasing the prob- lems size or going closer to reality, these systems increase in complexity and siz...

La luminancia es uno de los parámetros fundamentales de la luminotecnia. Es utilizada en muchas áreas, desde la evaluación de normativas, como el alumbrado público, hasta el diseño arquitectónico. Sin embargo, los ...

We sought to establish a sustainable 200 kV cryo-EM core facility for the Northern Rocky Mountain region with high resolution single particle capabilities. With modest funding, relative to 300 kV instruemnts, from th...

Aiming at the problem that the topology of low-voltage distribution network is complex and leads to low fault segment localization accuracy, a fault segment localization method based on voltage difference network mapping...

One of the main figures of merit in laser-ablative propulsion is the specific impulse, Isp, defined as the impulse per unit weight of fuel, and it is related to the exhaust velocity, ve, by the acceleration of gravity, I...

The research focuses on the analysis of the accuracy of attitude determination using satellite measurements from a multi-antenna Global Navigation Satellite System (GNSS). Carrier phase satellite measurements are charact...

The proposal of the carbon peaking and carbon neutrality target has promoted the transition of power dispatching to low-carbon. In response to the problem that existing multi energy power dispatching methods are difficul...

The integrated energy system, as a crucial physical form supporting the energy Internet, has rapidly expanded in scale under the continuous wave of technological innovation. The high integration of various energy sources...

Arc fault, especially series arc fault, has been the primary cause of electrical fire, which is intermittent, hidden, random and uncertain, difficult to detect, and serious harm. The characteristics of arc fault are firs...
