Falling rule lists are classification models consisting of an ordered list of if-then rules, where (i) the order of rules determines which example should be classified by each rule, and (ii) the estimated probability of success decreases monotonically down the list. These kinds of rule lists are inspired by healthcare applications where patients would be stratified into risk sets and the highes...

Sir, Pituitary infarction following Coronary Artery Bypass Grafting (CABG) is rare but may have serious debilitating effects. We present two cases of panhypopituitarism after CABG. BR, 56 years man who presented with repeated falls following CABG done eight months back. Of late he was pleasantly surprised to see wonderfully good glycaemic control, which he was struggling to get before. His BMI ...

Fear of falling (FF) can be considered as a protective response to a real threat, preventing the elderly from performing activities with high risk of falling, but can also lead to a restriction of the activities that will result in a long-term adverse effect on social, physical or cognitive functions. There is a prevalence of FF in 30% in the elderly who have no history of falls, and double tha...

There is a growing interest in simulating natural phenomena in computer graphics applications. Animating natural scenes in real time is one of the most challenging problems due to the inherent complexity of their structure, formed by millions of geometric entities, and the interactions that happen within. An example of natural scenario that is needed for games or simulation programs are forests...

In this study we consider the unsteady separated flow of an inviscid fluid (density ρf ) around a falling flat plate (thickness T , half-chord L, width W , and density ρs) of small thickness and high aspect ratio (T L W ). The motion of the plate, which is initially released from rest, is unknown in advance and is determined as part of the solution. The flow solution is assumed two-dimensional ...

The aim of this study was to verify changes in absolute power (qEEG), in theta, during the catch of a free falling object. The sample consisted of 10 healthy individuals, of both genders, with ages between 25 and 40 years. A three-way ANOVA followed by Post-Hoc analysis was applied. The results demonstrated main effects for time and position. In conclusion, a motor task that involves expectatio...

Whiplash Associated Disorders (WAD) has been reported as an adult phenomenon. Whiplash injury has classically been described as a cervical soft tissue hyperextension- flexion injury after a trauma such as a rear end impact car crash, contact sport injuries, blows to the head from a falling object or a punch and shaken baby syndrome and is mostly seen in adults . It is important as it may cause ...

Molecular dynamics studies of nanometer-sized rigid grains, droplets and bubbles in nanometer-sized pores indicate that the drag force may have a hydrodynamic form if the moving object is dense and small compared to the pore diameter. Otherwise, the behavior is nonhydrodynamic. The terminal speed is insensitive to whether the falling droplet is made of liquid or a solid. The velocity profiles w...

String theory provides an example of the kind of apparent inconsistency that the Principle of Black Hole Complementarity deals with. To a freely infalling observer a string falling through a black hole horizon appears to be a Planck size object. To an outside observer the string and all the information it carries begin to spread as the string approaches the horizon. In a time of order the “info...
