Figure 1 Kneeling trunk rotation (a) start position (b) final position. Sports such as tennis, golf, baseball, and hockey each involve a tremendous amount of trunk rotation. It is not just striking sports, but also throwing, kicking, running, swimming, skiing, etcwhichall require yourbody to rotate throughyour core. In order to transmit forces from your bigger, stronger leg muscles to your arms...

Electron emission from the sidewall of a bent individual multiwall carbon nanotube (CNT) is reported. The CNT was synthesized using a catalytic chemical vapor deposition method and the focused-ion beam technique was used to fabricate the CNT-based electron emitter. With controlled ion bombardment, individual carbon nanotubes can be bent into loops with different radii. An external electric fiel...

Force-directed layout is typically used to create organic-looking, straight-edge drawings of large graphs while combinatorial techniques are generally preferred for high-quality layout of small to medium sized graphs. In this paper we integrate edge-routing techniques into a forcedirected layout method based on constrained stress majorisation. Our basic procedure takes an initial layout for the...

When a viscoelastic fluid blob is stretched out into a thin horizontal filament, it sags and falls gradually under its own weight, forming a catenary-like structure that evolves dynamically. If the ends are brought together rapidly after stretching, the falling filament tends to straighten by rising. These two effects are strongly influenced by the elasticity of the fluid and yield qualitativel...

Mammalian mitotic chromosome morphogenesis was analyzed by 4D live-cell and snapshot deconvolution fluorescence imaging. Prophase chromosomes, whose organization was previously unknown, are revealed to comprise co-oriented sister linear loop arrays displayed along a single, peripheral, regularly kinked topoisomerase II/cohesin/condensin II axis. Thereafter, rather than smooth, progressive compa...

Chloroplast development during carposporogenesis in the parasitic red alga Faucheocolax attenuata Setch. was studied by electron microscopy. Proplastids are usually found in the peripheral cytoplasm of young carpospores and are characterized by the presence of portions of a peripheral thylakoid and coiled lamellar bodies that range in size up to 0.5 micron. One type of coiled lamellar body occu...

Face is a popular topic of research in computer vision, image analysis and understanding. This paper proposes a method to detect straight posed face as well as tilted face in colour images. Algorithm first detects skin colour region and then skin region is further processed by finding connected components and holes. Each connected components is tested to extract facial features and Y-value of e...

came on suddenly and gradually increased and assumed its present size, and was attended with excruciating pain extending down to the toes. On admission, a pulsating tumour, about the size of a duck's egg, was found occupying Scarpa's Triangle of the right thigh, extending upwards as far as Poupart's ligament. The whole tumour pulsated distinctly, with marked aneurismal thrill and bruit. The pat...

Resonant power conversion at MHz frequencies is useful for miniaturization of power electronics, but requires resonators or inductors with high efficiency. Because litz wire is not effective above several MHz, an alternative winding structure for inductors is required for operation at these frequencies. In this paper, we present resonators with a multi-layer foil winding which can be constructe...
