To prevent brain trauma, understanding the mechanism of injury is essential. Once the mechanism of brain injury has been identified, prevention technologies could then be developed to aid in their prevention. The incidence of brain injury is linked to how the kinematics of a brain injury event affects the internal structures of the brain. As a result it is essential that an attempt be made to d...

INTRODUCTION Because of the unusual anatomy of an anomalous origin of the right coronary artery from the left sinus of Valsalva, selective cannulation of the guiding catheter in percutaneous coronary intervention for these cases is always challenging. CASE PRESENTATION A 58-year-old Japanese man was admitted to our hospital complaining of worsening exertional chest pain. He was suspected of h...

Multi-satellite imaging mission planning (MSIMP) has been difficult in various scenarios due to the complex constraints of multi-satellite imaging, wide area covered by target points, and difficulty achieving different requirements a short period time with limited satellite resources. In addressing this challenge, work investigates based on Unified Plan Model Improved Adaptive Differential Evol...

The straddle-type monorail tour transit system is a light overhead steel structure, and the lateral stiffness generally low. However, limit of natural vibration frequency not clear in current codes China, designers may ignore it. Weak will lead to violent during vehicle operation crowds walking, affecting human comfort structural safety. Based on practical project, we tested acceleration under ...

Abstract System engineering (SE) methods and principles are nowadays widely adopted in the product development processes, especially industrial sector, where saving production time costs primary goals. This work describes an application of a particular SE methodology, V-model-based design, which system lifecycle is divided on basis graphical V-shaped scheme, called V-model. Following this appro...

Percutaneous balloon mitral valvoplasty (PBMV) has become the treatment of choice for severe pliable rheumatic mitral stenosis. The multi-track system is a recent variation of the double-balloon technique and is easier owing to the use of a monorail balloon and a simple, single-guidewire approach. In the present study, we used the double-coil Inoue metal wire with a multi-track balloon instead ...

In the modern era of interventional cardiology, stent delivery failure in complex, tortuous and/or calcific coronary anatomy is encountered in approximately 5% of cases, leading to incomplete revascularization and procedural failure. The GuideLiner® catheter (Vascular Solutions, MN, USA) is a monorail guide catheter extension that facilitates safe and effective delivery of balloons and/or stent...

Head impact research involving accelerometer based sensors in sports helmets has been well documented over the past decade; however, the maximum number of players involved in the largest continuous study was 314 over 3 years. Practical methods for using accelerometer arrays present significant power management issues and a requirement for high resolution data during direct head impact injury. T...
