most people infected with m .tuberculosis do not develop active disease. in healthy individuals, the lifetime risk of developing infection to disease is 5-10%. reactivation of tb often occurs in older children and adolescent and is more common in patients who acquire tb at age 7 years and older. pulmonary tuberculosis may manifest in several forms, including endobronchial tb with focal lymphade...

Cognitive Radio (CR) networks are emerging as new paradigm of communication and channels sharing in multimedia and wireless networks. In this paper, we address the problem of video transmission over shared CR networks using progressive compression source coding associated to fountain codes. We consider a TDMA-based transmission where many subscribers share the same infrastructure. Each Secondar...

progressive hemifacial atrophy, also known as parry-romberg syndrome, is an uncommon degenerative and poorly understood condition. it is characterized by a slow and progressive but self-limited atrophy affecting one side of the face. the incidence and the cause of this alteration are unknown. a cerebral disturbance of fat metabolism has been proposed as a primary cause. possible factors that ar...

background: corneal collagen cross-linking with riboflavin, also known as collagen cross-linking (cxl), involves the application of riboflavin solution to the eye that is activated by illumination with ultraviolet a (uva) light. we survey here the topographic corneal changes one year after cxl in patients with corneal keratoconus. materials and methods: this prospective randomized clinical tria...

infection with human immunodeficiency virus (hiv) is a progressive condition which may cause endothelial dysfunction and liver damage leading to coagulopathy. with adventure of highly active antiretroviral therapy (haart), life expectancy has prolonged in hiv positive patients but several acquired immunodeficiency syndrome (aids)-related conditions such as coagulopathies are responsible for ass...

Transmission of compressed image data over noisy channels is an important problem and has been investigated in a variety of scenarios. In this paper, we propose a progressive time-varying source-channel coding system for transmitting images over wireless channels. The core result of this paper is a systematic method of instantaneous rate allocation between the progressive source coder and chann...

In earlier work, we introduced the progressive mesh (PM) representation, a new format for storing and transmitting arbitrary triangle meshes. For a given mesh, the PM representation defines a continuous sequence of level-of-detail approximations, allows smooth visual transitions (geomorphs) between these approximations, supports progressive transmission, and makes an effective compression schem...
