Chronic hepatitis B virus(CHB)infection-estimated to affect 290 million individuals-remains the leading global cause of liver-related mortality and a risk factor for hepatocellular carcinoma(HCC)[1].Importantly,56% of liver cancers worldwide were attributable to CHB based on GLOBOCAN estimates from 2012[2].Current first-line therapies for CHB reduce but do not eliminate the risk of HCC,and for those fortunate enough to experience clearance of hepatitis B surface antigen(HBsAg),either spontaneous or on-treatment,the risk of HCC drops further but again persists[3,4].Additionally,unlike other etiologies of chronic liver disease,HCC develops in the absence of advanced fibrosis in up to 30% of HBsAg-positive patients[5].Taken together,these realities dictate that surveillance for HCC is paramount in nearly all circumstances for patients with CHB.

Pesticides are extensively utilized in modern farming to control pests and weeds, thereby ensuring high quality and quantity of crops. Aerial drifts and runoffs after rain transport these agrochemicals to aquatic bodies, where they adversely affect aquatic organisms. We carried out a study to assess the effects of carbaryl and dimethoate on esterase and antioxidant enzyme activities of tadpoles, adult frogs and juvenile fish. These organisms were exposed to sublethal contraptions of 2.9 ppm carbaryl and 4.8 ppm dimethoate for 96 hours. After the exposure period, the fish and frogs were sacrificed and post-mitochondrial fractions were prepared for enzymatic analysis. Acetylcholinesterase (AChE), carboxylesterase (CbE), superoxide dismutase, glutathione peroxidase and catalase were measured. Carbaryl and dimethoate inhibited the activities of acetylcholinesterase, carboxylesterase, superoxide dismutase (SOD), catalase (CAT) and glutathione peroxidase (GPx) in juvenile fish, tadpoles and adult frogs. Inhibition of SOD, CAT and GPx suggests that the two pesticides caused oxidative stress in the aquatic organisms, while inhibition of AChE and CbE affected the normal transmission of nerve impulses. The results indicate that the two pesticides affect the well-being of the studied aquatic organisms.

In this paper, we propose an automatic image based smoke detection using source separation. In particular, we assume that the region of interest(smoke region) is a linear combination of smoke and background pixels, and we estimate the smoke component. More specifically, we extend the linear hyperspectral unmixing techniques to the context of image based smoke detection in order to separate the smoke component from the background. The proposed approach yields promising results especially with smoke images captured outdoor.
