The head pose estimation problem is well known to be a challenging task in computer vision and is a useful tool for several applications involving human-computer interaction. This problem can be stated as a regression one where the input is an image and the output is pan and tilt angles. Finding the optimal regression is a hard problem because of the high dimensionality of the input (number of ...

Automated code generators for finite element local assembly have facilitated exploration of alternative implementation strategies within generated code. However, even for a theoretical performance indicator such as operation count, an optimal strategy for local assembly is unknown. We explore a code generation strategy based on symbolic integration and polynomial common sub-expression eliminati...

BACKGROUND The aim of the present study was to compare the in vivo articulation of the healthy knee to the contralateral knee of subjects with acute and chronic PCL injuries. METHODS Magnetic resonance was used to generate sagittal images of 10 healthy knees and 10 knees with isolated PCL injuries (5 acute and 5 chronic). The subjects performed a supine leg press against a 150 N load. Images ...

A study was conducted in two selected sites (Anuradhapura and Puttlam districts) to phenotypic ally characterize various types of village chicken present in Sri Lanka. Qualitative traits such as characteristics of plumage, comb, shank, eye and earlobe, and body condition score were recorded with a full inventory of management conditions. Quantitative traits included body weight and linear morph...

A new air traffic control tower research facility dedicated to countering potential air and runway traffic problems at commercial airports is advancing the stateof-the-art in aviation research at the National Aeronautics and Space Administration (NASA) Ames Research Center. FutureFlight Central (FFC), is a unique real-time simulator designed to safely study new technologies, airport design chan...

Self-organization of cytoskeletal proteins such as actin and tubulin into filaments and microtubules is frequently assisted by the proteins binding to them. Formins are regulatory proteins that nucleate the formation of new filaments and are essential for a wide range of cellular functions. The vertebrate inverted formin 2 (INF2) has both actin filament nucleating and severing/depolymerizing ac...

Background: Households’ financial protection against health payments and expenditures and equity in utilization of health care services are of the most important tasks of governments. This study aims to measuring equity in household’s health care payments according to fairness in financial contribution (FFC) and Kakwani indices in Tehran-Iran, 2013. Methods: This cross-sectional study was c...

Background and purpose: In 2000 World Health Organization (WHO) has announced the fairness of financial contribution to health care costs, as one of the three goals of health systems. However, conducted studies in Iran reflect the dire situation in the context of health equity in terms of financing health care costs. The aim of the present study is to determine the disparities in health expendi...

This study investigated the relationship between front foot contact (FFC) ground reaction forces (GRF) during delivery stride, lower-limb strength, eccentric dexterity and power, ball release speed (BRS) among pace bowlers. Thirteen high-level male bowlers performed double single leg drop landings; isometric mid-thigh pull; countermovement jump; bowling (two-over spell measuring BRS FFC GRF). T...
