This paper describes a representation of the dynamics of human walking action for the purpose of person identification and classification by gait appearance. Our gait representation is based on simple features such as moments extracted from video silhouettes of human walking motion. We claim that our gait dynamics representation is rich enough for the task of recognition and classification. The...

We study a dynamic coordination process in which agents are uncertain about the actions of their fellow agents, and anticipate strategically relevant information. Because of the uncertainty and learning, (ir)reversibility of actions has important strategic consequences. We find that the reversibility option can either enhance or hamper efficient coordination, and we characterize the direction o...

Background: Chronic low back pain (CLBP) disability has been particularly frustrating because its treatment has been a great therapeutic challenge. Disability has been suggested to depend on different factors that should be found and considered in the medical management. The inter-segmental coordination is often impaired in CLBP subjects; however, to the best of our knowledge, there is no evide...

Segmental neurofibromatosis is a rare clinical finding generally with no family history and facial involvement. There are four subtypes of segmental neurofibromatosis: true segmental, localized cases with deep involvement, hereditary segmental and bilateral segmental neurofibromatosis. Here we report three patients from the same family (father, son and granddaughter) with segmental bilateral ne...

The aim of this paper is twofold: 1) to examine the nature, scope and function o f the paralinguistic features on the basis o f a survey of the previous studies, and 2) to make an attempt to search and exempli fy paralinguistic features operating at vari ous linguistic and non-linguistic units in s everal languages. A special emphasis will be placed on the paralinguistic functions o f phonetic ...

Productions in a foreign language (L2) are commonly affected by segmental and suprasegmental features of the phonetic/phonological system of the mother tongue (L1). As for the segmental level, the sounds of the L2, which are close or similar to others of the L1, are deeply influenced by the native system; these influences are perceived as foreign accent but could also be acceptable from the poi...

Only very few phonological processes are reported to be conditioned by stress. There are two major patterns of stress-sensitive processes: segments are lengthened under stress, and vowels become louder. Two other phonological patterns are reported in the presence of stress, although they don’t seem to enhance prominence of the stressed position: the preservation of segmental contrast and the en...

BACKGROUND AND PURPOSE Injury to spinal segmental arteries may potentially occur during spinal surgery, particularly during anterior or minimally invasive approaches. Use of a noninvasive radiologic tool to evaluate these arteries before surgery may reduce this risk. MATERIAL AND METHODS We performed spinal CT angiography and reconstructed 3D images of segmental arteries in 41 patients. We cl...

In this paper, mimicry speech is analysed using features at suprasegmental, segmental and subsegmental levels. The possibility of the imitator getting close at each of these levels is examined here. The imitator cannot duplicate all features of the target, as imitation depends on the target speaker, utterance chosen, and his ability to imitate. To study the variation of features in the case of ...
