In this study, segmental and prosodic aspects of word repetition and non-word repetition in typically developing children aged four to six years were investigated. Focus was on developmental differences, and on how tonal word accent and word length affect segment production accuracy. Prosodically controlled words and non-words were repeated by 44 Swedish-speaking children. Repetition accuracy f...

This study sought to investigate navigational strategies across the life span, by testing 8-years old children to 80-years old healthy older adults on the 4 on 8 virtual maze (4/8VM). The 4/8VM was previously developed to assess spontaneous navigational strategies, i.e., hippocampal-dependent spatial strategies (navigation by memorizing relationships between landmarks) versus caudate nucleus-de...

Caffeine and its derivatives have been used, alone and in combination with other phytochemicals, as weight-loss supplements. Caffeine impacts several physiological and behavioral aspects of energy balance. Here, we investigate the potential for caffeine to enhance non-exercise activity thermogenesis (NEAT) even when activity level is held constant. To do this, muscle thermogenesis and energy ex...

We demonstrate a soliton fiber laser with 280-fs pulses at 408-MHz repetition rate, and a stretched-pulse regime fiber laser with 102-fs pulses at 234-MHz repetition rate. Both use saturable Bragg reflectors for mode-locking and/or self-starting. Introduction Compact sources of femtosecond laser pulses are an attractive and versatile technology for a variety of applications, such as frequency m...

results there was a significant difference in the self-esteem (p = 0.003), life satisfaction (p = 0.001), efficiency (p = 0.00), positive mood (p = 0.00), mental health (p = 0.001) and happiness (p = 0.001) among elderly women in the case group before and after a regular six-week walking program. conclusions according to the results, walking increases the happiness and mental health of elderly ...

Given that falls most commonly occur during walking due to unexpected balance perturbations like trips and slips, walking-based assessment including stability adaptability such could be beneficial for fall risk in older adults. This cross-sectional study reanalyzed data from two larger studies conducted with the same protocol. Participants completed unperturbed trials at speeds of 0.4 m/s up 1....

In this paper, we present our design and experiments on a planar biped robot under the control of a pure sensor-driven controller. This design has some special mechanical features, for example small curved feet allowing rolling action and a properly positioned center of mass, that facilitate fast walking through exploitation of the robot’s natural dynamics. Our sensor-driven controller is built...

Unisexual Trichogramma forms have attracted much attention due to their potential advantages as biocontrol agents. Fitness studies have been performed and understanding the cost that Wolbachia may inflict on their hosts will help in deciding if Wolbachia infected (unisexual) forms are indeed better than sexual forms when used in biological control programmes. The influence of Wolbachia on the f...
