PURPOSE Slipped capital femoral epiphysis (SCFE) is one of the most common adolescent hip conditions. Unstable SCFE is characterized by sudden and severe hip pain with the inability to weight bear, even with crutches. Osteonecrosis of the femoral head is increased in patients with unstable SCFE. The aim of our study was to systematically review the literature that compares hip decompression to ...

At present, no decompression algorithm is able to predict safe decompression for all dive scenarios. In practice, empirical adjustments are made by experienced organisations or divers in order to improve decompression profiles for the range of depths and durations needed on any particular dive. Bubble formation and growth in the human body are the fundamental causes of decompression sickness, a...

In this paper, we propose an alternative design approach for multistandard video decompression systems. The key component of our proposal is a self−contained and extensible meta data format for unified description of image processing and reconstruction operations. Dividing between the syntactic layer of the video coding schemes and the signal processing part, the meta data format offers the opt...

This paper describes a new XML compression scheme that offers both high compression ratios and short query response time. Its core is a fully reversible transform featuring substitution of every word in an XML document using a semi-dynamic dictionary, effective encoding of dictionary indices, as well as numbers, dates and times found in the document, and grouping data within the same structural...

Apneusis, or apneustic respirations, is characterized by an abnormal breathing pattern involving gasping and the inability to fully expire. A loss of gag reflex and other cranial nerve deficits are also often accompanied with these respiratory changes. In neurological intensive care units (NICUs), these respiratory and airway changes are not uncommon and have been well documented (Lee et al. 19...

Secondary avascular necrosis of the knee is a common finding among HIV patients on anti retroviral therapy. Incidence in this group is higher than in the general population. There is no clear understanding of the pathophysiology of the disease. It is thought to be related to the virus itself and/or anti retroviral medications. Early recognition and management of knee pain reduces the need of ex...

Numerous evidences of hot heterogeneous accretion the Earth have been obtained. According to these data, Early Precambrian crystalline complexes and acidic crust were resulted from emerging residual melts formed by low-pressure compression fractionation bottom parts early magmatic ocean. The rise various layers ocean, crystallized top bottom, caused evolution magmatism ancient platforms basic, ...

This special edition of the Biomedical Journal focuses on experimental autoimmune encephalomyelitis, and includes three reviews showing how this model has greatly facilitated our understanding of the pathophysiology of multiple sclerosis. We also highlight a small single center study which suggests that the use of calcium bone substitutes during core decompression surgery may do more harm than ...

This paper reviews various optimization techniques available for training multi-layer perception (MLP) artificial neural networks for compression of images. These optimization techniques can be classified into two categories: Derivative-based and Derivative free optimization. The former is based on the calculation of gradient and includes Gradient Descent, Conjugate gradient, Quasi-Newton, Leve...
