The movements of animals, people, and vehicles are embedded in a geographic context. This context influences the movement and may cause the formation of certain behavioral responses. Thus, it is essential to include context parameters in the study of movement and the development of movement pattern analytics. Advances in sensor technologies and positioning devices provide valuable data not only...

This study aimed to quantify the time-motion demands and intra-team movement synchronization during the pre-season matches of a professional soccer team according to the opposition level. Positional data from 20 players were captured during the first half of six pre-season matches of a Portuguese first league team. Time-motion demands were measured by the total distance covered and distance cov...

Complementation of movement and coat proteins of the orchid-infecting potexvirus Cymbidium mosaic virus (CymMV) and tobamovirus Odontoglossum ringspot virus (ORSV) was investigated. Nicotiana benthamiana, which is susceptible to both CymMV and ORSV, was used as a model system. Four transgenic lines, each harbouring one of the movement protein (MP) or coat protein (CP) genes of CymMV or ORSV, we...

Global navigation satellite systems such as the Global Positioning System (GPS) is one of the most important sensors for movement analysis. GPS is widely used to record the trajectories of vehicles, animals and human beings. However, all GPS movement data are affected by both measurement and interpolation errors. In this article we show that measurement error causes a systematic bias in distanc...

The present paper proposes a technical analysis method for extracting information about movement patterning in studies of motor control, based on a cluster analysis of movement kinematics. In a tutorial fashion, data from three different experiments are presented to exemplify and validate the technical method. When applied to three different basketball-shooting techniques, the method clearly di...

In this paper, we present a novel localized movement control algorithm to form a fault-tolerant bi-connected robotic network topology from a connected network, such that total distance of movement of robots is minimized. The proposed distributed algorithm uses p-hop neighbor information to identify critical head robots that can direct two neighbors to move toward each other and bi-connect their...

Blindfolded participants performed one-dimensional movements towards a mechanical stop and back to the start. After a varying delay, they had to reproduce the encoded target position by a second mechanically unrestricted movement. Average event-related potentials accompanying the "encoding" and the "reproduction" movements revealed a biphasic waveshape over primary sensorimotor areas. The first...

Voltage-gated ion channels respond to changes in membrane potential by movement of their voltage sensors across the electric field between cytoplasmic and extracellular solutions. The principal voltage sensors in these proteins are positively charged S4 segments. The absolute magnitude of S4 movement discriminates two competing classes of gating models. In one class, the movement is <10 Angstro...

Restriction of long-distance movement of tobacco etch virus (TEV) in Arabidopsis ecotype Col-0 plants requires the function of at least three genes: RTM1 (restricted TEV movement 1), RTM2, and RTM3. The mechanism of TEV movement restriction remains poorly understood, although it does not involve a hypersensitive response or systemic acquired resistance. A functional characterization of RTM1 and...

1Some of this data have been presented in abstract form at the 1995 Society for Neuroscience conference, San Diego, and the 1996 Biomechanics and Neural Control of Movement conference, Ohio. Abstract Young and elderly subjects performed aiming movements to a visual target with a manipulandum to determine whether the elderly reduce their reliance on visual feedback after extended practice. Relia...
