Active force-feedback holds the potential for precise and rapid controls. A high performance device can be built from a surplus disk drive and controlled from an inexpensive microcontroller. Our new design,The Plank has only one axis of force-feedback with limited range of motion. It is being used to explore methods of feeling and directly manipulating sound waves and spectra suitable for live ...

Inspired by the modeling of grain growth in polycrystalline materials, we consider a nonlinear Fokker–Plank model, with inhomogeneous diffusion and variable mobility parameters. We develop large time asymptotic analysis such nonstandard models reformulating extending classical entropy method, under assumption periodic boundary condition. In addition, illustrative numerical tests are presented t...

On behalf on the ATLAS and CMS collaborations The introduction of extra space dimensions in the theory could be an elegant way to solve the hierarchy problem. There could even be one energy scale at which all interactions could unify. The limits coming from our knowledge of the gravitation at low distance allow this energy scale to be as low as few TeV. This situation is extremely interesting e...

BACKGROUND Among older people, undue risk taking could lead to falls, irrespective of physical ability. We investigated the interaction between risk-taking behavior and physical ability and its contribution to falls. METHODS Participants (N = 294, age ≥ 70) were asked to walk as quickly as possible to a visible destination by choosing one of six paths. Each contained a raised plank that had t...

This study aimed to examine the effects of kinesiology taping (KT) and different TRX suspension workouts on the amplitude of electromyographic (EMG) activity in the core muscles among people with chronic low back pain (LBP). Each participant (total n = 21) was exposed to two KT conditions: no taping and taping, while performing four TRX suspension exercises: (1) hamstring curl, (2) hip abductio...

In the Theory of Heat Radiation, Max Plank [1959] states that “so far as their physical properties are concerned, heat rays are identical with light rays of the same wavelength”. His book, which contains much of the basis upon which modern radiation heat transfer is based, does not consider the phenomenon of diffraction “on account of its complicated nature”. Plank goes on to say “[i]t will be ...

A cause of limited physical activity levels in youth is the presence of low back pain (LBP), therefore proper assessment of low back function in physical education settings is needed to identify children who may be at risk. The purpose of this study was to determine the concurrent and criterion-referenced validity of field tests of low back and core muscular endurance in school-aged children. T...

In 2010, Resch and Plank proposed a computationally secure secret sharing scheme, called AONT-RS. We present a generalisation of their scheme and discuss two ways in which information is leaked if used to distribute small ciphertexts. We discuss how to prevent such leakage and provide a proof of computational privacy in the random oracle model. Next, we extend the scheme to be robust and prove ...

Individuals with Parkinson's disease (PD) commonly experience freezing of gait under time constraints, in narrow spaces, and in the dark. One commonality between these different situations is that they may all provoke anxiety, yet anxiety has never been directly examined as a cause of FOG. In this study, virtual reality was used to induce anxiety and evaluate whether it directly causes FOG. Fou...
