An accurate ego-motion estimation solution is vital for autonomous vehicles. LiDAR widely adopted in self-driving systems to obtain depth information directly and eliminate the influence of changing illumination environment. In odometry, lack descriptions feature points as well failure assumption uniform motion may cause mismatches or dilution precision navigation. this study, a method perform ...

BACKGROUND There are no data on optimal cut-off points to classify obesity among Omani Arabs. The existing cut-off points were obtained from studies of European populations. OBJECTIVE To determine gender-specific optimal cut-off points for body mass index (BMI), waist circumference (WC) and waist-to-hip ratio (WHR) associated with elevated prevalent cardiovascular disease (CVD) risk among Oma...

Objective To develop an internationally acceptable definition of child overweight and obesity, specifying the measurement, the reference population, and the age and sex specific cut off points. Design International survey of six large nationally representative cross sectional growth studies. Setting Brazil, Great Britain, Hong Kong, the Netherlands, Singapore, and the United States. Subjects 97...

Using a 400 ?J ytterbium laser combined with novel pulse compression technique, we demonstrate state-of-the-art terahertz (THz) source from the tilted-pulse front pumping scheme in lithium niobate at room temperature record efficiency of 1.3% capable generating 74 mW average power and kV/cm focus. Key points this demonstration include use pump duration 280 fs combination stair-step echelon mirr...

In this paper‎, ‎we propose a modification of the second order method‎ ‎introduced in [‎‎Q.
