We present Spitzer 70 and 160 μm observations of the COSMOS Spitzer survey (S-COSMOS). The data processing techniques are discussed for the publicly released products consisting of images and source catalogs. We present accurate 70 and 160 μm source counts of the COSMOS field and find reasonable agreement with measurements in other fields and with model predictions. The previously reported coun...

Macular amyloidosis (MA) is the subtlest of cutaneous varieties amyloidosis. In general, treatment MA disappointing. Hence, this study was aimed at comparing two modalities for same. To compare efficacy 30% TCA chemical peel with Q switched Nd-YAG laser 1064nm in macular 50 patients attending our Dermatology outpatient department were enrolled study. The involved application 25 an interval 2 we...

INTRODUCTION Neonatal diabetes (ND) presents below 6 months of age, and is caused by a genetic defect in glucose homeostasis. Molecular genetic diagnosis can identify the exact molecular aetiology and guide clinical management. The objective of this study was to identify ND among children with diabetes in a major children's hospital in Singapore and to characterise their molecular and clinical ...

BACKGROUND AND DESIGN The removal of benign, aesthetically important, pigmented lesions can be effectively treated with multiple modalities. Selective removal of the pigment by lasers is becoming increasingly popular. A three-center trial evaluated the effectiveness of the frequency-doubled Q-switched neodymium (Nd):YAG laser (532 nm, 2.0-mm spot size, 10 nanoseconds) in removing benign epiderm...

Intra-cavity binary phase elements are incorporated into a -switched Nd : YAG laser resonator to obtain efficient high-order transverse mode selection. The resonator configuration is analyzed using the propagation-matrix diagonalization method and the Fox–Li algorithm, and a simple model for predicting the relative output powers of the selected modes is developed. The predicted results are veri...

This paper presents an approach for solving optimal control problems of switched systems. In general, in such problems one needs to nd both optimal continuous inputs and optimal switching sequences, since the system dynamics vary before and after every switching instant. After formulating the optimal control problem, we propose a two stage optimization methodology for it. Since many practical p...
