Channel Network Control on Seasonal Lake Area Dynamics in Arctic Deltas
Published 2020“…We find that monthly shrinkage rates have a pronounced structured variability around the channel network with the shrinkage rate systematically decreasing farther away from the channels. This pattern of shrinkage is predominantly attributed to a deeper active layer enhancing near-surface connectivity and storage and greater vegetation density closer to the channels leading to increased evapotranspiration rates. …”

The rising danger of heat waves
Published 2015“…The model, which is based on daily meteorological data from 2000 to 2012, suggests that at least 87% of Qatari infants under 4 years of age, as well as more than 86% of elderly people and 80% of the general population could be exposed to hazardous heat wave events at least once in the next five years. According to the model, heat waves are most likely to occur in Qatar’s northern coastal region, largely because of increased humidity and temperature as a result of air pollution from expansion of the oil and gas industries. …”

Effectiveness of Positron Emission Tomography for Predicting Chemotherapy Response in Colorectal Cancer Liver Metastases
Published 2010“…For example, a few years ago an extrahepatic metastasis effectively eliminated surgical resection, but a combination of chemotherapeutic options and surgical techniques has expanded the indications for resection and increased the population of patients who may benefit.1,2 Neoadjuvant chemotherapy has increased the resectability rate by 11% to 37%.1 Unfortunately, greater than 80% of patients undergoing hepatic resection will have recurrences, mostly within the first 2 years.2 Nonetheless, the only hope for cure is resection, and prior surgical dogma based on the number of lesions, size of the tumor-free resection margin, and presence of resectable extrahepatic disease must be questioned.3- 5 The current standard approach to surgical planning is contrast-enhanced computed tomography (CT) or magnetic resonance imaging (MRI) for specific tumor characteristics or contraindications to CT.6 Several series showed that focal extrahepatic disease, an isolated pulmonary lesion, can be safely resected, with 5-year survival rates of 29% to 58%.7,8 In 1 series,7 17 of 30 patients required 3 or more resections. …”
