Commenting on a recent editorial in this journal which presented four challenges global health networks will have to tackle to be effective, this essay discusses why this type of analysis is important for global health scholars and practitioners, and why it is worth understanding and critically engaging with the complexities behind these challenges. Focusing on the topics of problem definition ...

Biological effects due to whole-body radio-frequency exposure may be induced by core temperature elevation. According to the international safety guidelines/standards for human protection, the whole-body averaged specific absorption rate (WBA-SAR) is used as a metric. In order to understand the relationship between WBA-SAR and core temperature elevation, a theoretical solution or a closed formu...

With the significant decrease in natural gas prices in many parts of the world, the employment of gas turbine (GT) units has increased steadily in recent years. The ever-increasing deployment of GT units is strengthening the interconnections between electric power and natural gas systems, which could provide a higher level of operational flexibility and reliability. As a result, the planning an...

The demand for network bandwidth is growing much faster than the increase in commercially available memory bandwidth, causing a growing interest in input-queued switches. Furthermore, an increase in the proportion of multicast traffic in today's networks makes it important that they support such traffic efficiently. This paper presents the design of the scheduler for an MxN input-queued multica...

Whole brain segmentation referred as skull stripping, it is an important process in neuriomage analysis. Automatic segmentation of brain tissues from magnetic resonance images (MRI) remains a challenging task due to variation in shape and size, use of different pulse sequences, overlapping signal intensities and imaging artifacts. Level sets and active contour methods have tremendous potential ...
