We introduce and solve a new problem inspired by energy pricing schemes in which a client is billed for peak usage. At each timeslot the system meets an energy demand through a combination of a new request, an unreliable amount of free source energy (e.g. solar or wind power), and previously received energy. The added piece of infrastructure is the battery, which can store surplus energy for fu...

There are some important indications in mini lesions (MLs), such as benign melanocytic lesions and superficial nevi. Shave excision, which is performed to treat these kind of lesions (figure 1), is frequently applied; but, the possibility of recurrence and the actual cosmetic results achieved with this procedure (shave excision) remains a controversial issue (Ferrandız, 2005; Bong et al., 2003;...

BACKGROUND In recent years, there has been a shift toward minimally invasive procedures. In hair transplantation surgery, this trend has manifested with the emergence of follicular unit extraction (FUE). Recently, a robot has been introduced for FUE procedures. OBJECTIVE To determine the transection rate of a robotic FUE device. MATERIALS AND METHODS The authors discuss the procedure, techn...

The analysis of high-throughput data sets, such as microarray data, often requires that individual variables (genes, for example) be grouped into clusters of variables with highly correlated values across all samples. Gene shaving is an established method for generating such clusters, but is overly sensitive to the input data: changing just one sample can determine whether or not an entire clus...

Fibrous dysplasia is a benign osseous disease, although radical resection is commonly recommended because of the possibility of recurrence or malignant change. However, radical resection is undesirable, particularly in the maxillofacial region, because facial bones are difficult to replace in an aesthetically-pleasing manner after radical excision. In our department, conservative shaving, as re...

BACKGROUND Axillary hair can influence the development of underarm odor in men. OBJECTIVE To compare different hair removal procedures and their impact on the effectiveness of standard soap washing (SW) in reducing male axillary odor. METHODS The axillae of healthy Caucasian males (N = 30; 18-48 years of age) were randomized in a non-crossover, split body design. Two of four axillary treatm...
