Causes of falling are multi-factorial. Although it is not easy to identify specific causes of falling, it is necessary to detect the significant causes of falling in each individual. In particular, use of medications and indoor hazards are important factors. We need to give instructions to families who live together with older persons how to avoid dangers of falling. Exercise has been proven to...

BACKGROUND Little is known about the prevalence rates and correlates of fear of falling and avoidance of activity due to fear of falling in the general population of community-living older people. OBJECTIVE To assess prevalence rates and study correlates of fear of falling and avoidance of activity due to fear of falling in this population. STUDY DESIGN AND SETTING cross-sectional study in ...

We examine two different methods for finding rising words (among which neologisms) and falling words (among which archaisms) in decades of magazine texts (millions of words) and in years of tweets (billions of words): one based on correlation coefficients of relative frequencies and time, and one based on comparing initial and final word frequencies of time intervals. We find that smoothing fre...

OBJECTIVE To identify the risk factors for falling after stroke, to establish the relation with lesion localisation, and to evaluate the incidence of falling. METHODS The falling history and the mood of 293 patients with stroke were investigated by a standard questionnaire. Other information (time since stroke, risk factors, and CT) about patients was obtained from their hospital records. R...

OBJECTIVES To evaluate the effects of a multicomponent cognitive behavioral intervention on fear of falling and activity avoidance in older adults. DESIGN Randomized controlled trial. SETTING Community-dwelling adults in the Netherlands. PARTICIPANTS Five hundred forty adults aged 70 and older who reported fear of falling and fear-induced activity avoidance (280 intervention, 260 control)...

The use of computer graphics to produce special effects is currently being applied with great results in especially the entertainment and game industry. One area where computer graphics is not quite ready to replace all real effects is natural phenomena where a lack of general models exists. In this work we present a general model for falling and accumulating snow. The appearance and movement o...

A simple setup was assembled to study the motion of an object while it falls. The setup was used to determine the instantaneous velocity, terminal velocity and acceleration due to gravity. Also, since the whole project was done within $20 it can easily be popularized.

String theory tells us that quantum gravity has a dual description as a field theory (without gravity). We use the field theory dual to ask what happens to an object as it falls into the simplest black hole: the 2-charge extremal hole. In the field theory description the wavefunction of a particle is spread over a large number of ‘loops’, and the particle has a well-defined position in space on...

We revisit the tidal stability of extrasolar systems harboring a transiting planet and demonstrate that, independently of any tidal model, none but one (HAT-P-2b) of these planets has a tidal equilibrium state, which implies ultimately a collision of these objects with their host star. Consequently, conventional circularization and synchronization timescales cannot be defined because the corres...
