Blind image deconvolution is an ill-posed problem that requires regularization to solve. However, many common forms of image prior used in this setting have a major drawback in that the minimum of the resulting cost function does not correspond to the true sharp solution. Accordingly, a range of workaround methods are needed to yield good results (e.g.… (More)
BACKGROUND A comparative study between two treatment methods (collagenase injection and open partial fasciectomy) for Dupuytren's contracture. This study will determine differences in clinical outcome, complication rate and patient satisfaction. METHODS 37 patients with 62 metacarpophalangeal joints (MCP) and 44 proximal interphalangeal joints (PIP)… (More)
Chondrogenic differentiated mesenchymal stem cells (CMSCs) have been shown to produce superior chondrogenic expression markers in vitro. However, the use of these cells in vivo has not been fully explored. In this study, in vivo assessment of cartilage repair potential between allogenic-derived chondrogenic pre-differentiated mesenchymal stem cells and… (More)
ABSTRACT Transverse sacral fracture is a very rare injury and frequently missed or delayed in diagnosis. We present a case with this injury and discuss its management. KEY WORDS Transverse, sacral fracture- dislocation, displacement.
BACKGROUND Marine stings and envenomation are fairly common in Malaysia. Possible contact to various marine life occurs during diving, fishing and food handling. Even though majority of fish stings are benign, there are several venomous species such as puffer fish, scorpion fish, lionfish, stingray and stonefish that require urgent medical treatment.… (More)
Diierential cryptanalysis is a powerful attack developed by Eli Biham and Adi Shamir. It has been successfully applied to many DES-like cryptosystems. We provide a brief introduction to their paper BS91] and show how to apply diierential cryptanalysis to attack the Data Encryption Standard (DES) reduced to 5 rounds.
