[Purpose] The purpose of this study was to compare the gait parameters of age-matched people with a normal gait (≥ 65 years), age-matched people with knee pain, and age-matched people with walker dependent gait at a self-selected gait speed. [Methods] Subjects walked on even ground in bare feet and were allowed a natural arm swing on a 6-m walkway. Walker-dependent participants walked on a walk...

The historical origins of Fermi-Walker transport and Fermi coordinates and the construction of Fermi-Walker transported frames in black hole spacetimes are reviewed. For geodesics this transport reduces to parallel transport and these frames can be explicitly constructed using either Killing or Killing-Yano tensors, the latter route chosen by Marck. For accelerated or geodesic circular orbits i...

This paper presents the motivation expressions of Smart Walker, which is intended for use during rehabilitation exercise for the recovery of walking ability. Smart Walker is the application of a robotic system for the elderly. Its main purposes are to improve mobility and maintain balance, though it can also be used as a rehabilitation assistant for patients who have trouble walking as a result...

We have shown that Walker 256/S mammary carcinoma caused osteoporosis-like changes in young female rats, accompanied by low serum estradiol and hypercalciuria without changes in the serum levels of calcium, phosphorus, and parathyroid hormone-related peptide. In this study, we investigated the cause of bone loss after Walker 256/S inoculation into female 6-week-old Wistar Imamichi rats, focusin...

The Tree Builder Random Walk is a special random walk that evolves on trees whose size increases with time, randomly and depending upon the walker. After every s steps of walker, number vertices are added to tree attached current position These processes share similarities other important classes Markovian non-Markovian walks presenting large variety behaviors according parameters specification...

A new genus of Lymantriinae, Maeoproctis gen. nov. has been proposed with Euproctis latifascia (Walker) as its type species. The morphological descriptions and diagnosis have also provided for the genus. Another species subfasciata Walker shifted under a combination comb.

Molecular machines have previously been designed that are propelled by DNAzymes, protein enzymes and strand displacement. These engineered machines typically move along precisely defined one- and two-dimensional tracks. Here, we report a DNA walker that uses hybridization to drive walking on DNA-coated microparticle surfaces. Through purely DNA:DNA hybridization reactions, the nanoscale movemen...

Perception of biological motions plays a major adaptive role in identifying, interpreting, and predicting the actions of others. It may therefore be hypothesized that the perception of biological motions is subserved by a specific neural network. Here we used fMRI to verify this hypothesis. In a group of 10 healthy volunteers, we explored the hemodynamic responses to seven types of visual motio...

A lecture hall full of people played a computer game together. Their goal was to keep a tightrope walker balanced. Each had a handset that could deliver a left or right nudge. The tightrope walker was also pelted by tomatoes which knocked him off balance. Across several games, the difficulty of the task was changed by the frequency of tomatoes and whether or not they were visible. After each ga...
