conclusions we reported a rare case of large residual cyst. dental practitioners should consider this lesion in the differential diagnosis of radiolucent lesions of the jaw bone. case presentation a 59-year-old iranian man complaining of a dull pain in his left side of the mandible after falling down one month ago was referred to the department of oral and maxillofacial pathology, hamadan unive...

The Roelofs effect is a distortion of perceived space that occurs when a large frame whose center is offset left or right from the objective midline is presented visually to an observer and causes a bias in the observer's subjective judgment of midline. Experiments were designed to test whether an isolated fragment (left or right end) of a Roelofs-inducing frame was capable of generating the Ro...

Human activity recognition (HAR) has been a popular research topic, because of its importance in security and healthcare contributing to aging societies. One of the emerging applications of HAR is to monitor needy people such as elders, patients of disabled, or undergoing physical rehabilitation, using sensing technology. In this paper, an improved version of Very Fast Decision Tree (VFDT) is p...

We investigate the black hole string transition in the two-dimensional Lorentzian black hole system from the exact boundary states that describe the rolling D-brane falling down into the two-dimensional black hole. The black hole string phase transition is one of the fundamental properties of the non-supersymmetric black holes in string theory, and we will reveal the nature of the phase transit...

The Timed "Up & Go" (TUG) is a representative mobility test for assessing the falling risk of the elderly. Although several tests have been developed, including the TUG, these do not include a "tripping" element, and tripping is a major cause of falling. This study examined the influence of various obstacle heights on test performance in the TUG test and test-retest reliability. Twenty-two heal...

The aging process may lead to the degradation of lower extremity function in the elderly population, which can restrict their daily quality of life and gradually increase the fall risk. We aimed to determine whether objective measures of physical function could predict subsequent falls. Ground reaction force (GRF) data, which was quantified by sample entropy, was collected by foot force sensors...

OBJECTIVE Jumping from high place for the purpose of suicide results in various damages to body area. A burst fracture of vertebrae is representative of them and we reviewed eight patients who were diagnosed with spinal burst fracture following suicide falling-down. The demographics, characteristics, performed operation, combined injuries, psychological past histories of the patients were analy...

Bilateral anterior shoulder dislocations are rarely seen and usually occur due to the same mechanism arising from traumatic injuries. In here, we discussed three cases of traumatic bilateral anterior shoulder dislocation , one had an additional patella fracture, and the other one had bilateral tuberculum majus fracture. All of the patients were female and our first case that presented here was ...

The most common interference causing human gait instability is slippery ground [1]. Falling caused by the interference of slippery ground is one of the serious security problems in the occupational environment [2]. Yamaguchi et al. pointed out that falling was the main accident in the industrial apartment and up to 50% of the occupational harm [3]. Therefore, a large number of researches have b...
