application of radioactive isotopes is the treatment of choice around the globe for many cancer sites. in this technique, the accuracy of the radiation delivery is highly dependent on the accuracy of radiation dosimetry around individual brachytherapy sources. moreover, in order to have compatible clinical results, an identical method of source dosimetry must be employed across the world. this ...

We propose a new online sortition protocol which is decentralized. We argue that our protocol has safety, fairness, randomness, non-reputation and openness properties. Sortition is a process that makes random decision and it is used in competitions and lotteries to determine who is the winner. In the real world, sortition is simply done using a lottery machine and all the participa...

BACKGROUND Low adherence to dietary guidelines and a concurrent rise of obesity-related chronic diseases emphasize the need for effective interventions to promote healthy eating. There is growing recognition that behavior change interventions should draw on theories of behavior change. Online interventions grounded in theory lead to increased effectiveness for health behavior change; however, f...

Metabolic diseases in China have been on the rise during recent decades. To investigate dietary glycaemic load (GL) and its correlation with the prevalence of metabolic diseases in hospitalised Chinese adults, we analysed the total energy and macronutrient intakes in 1040 patients. Dietary GL was calculated based upon glycaemic index (GI), carbohydrate content and daily intake of individual foo...

While it is recognised that humans are constantly exposed to plastics, there limitations in understanding the extent of this exposure, particularly dietary exposure. This lack information partly due challenges with analysis complicated matrices. study aimed assess impact medium high lipid content (> 3%) food samples on accurate quantification polyethylene (PE), using pyrolysis-gas chromatogr...
