With the decrease in the cost and in the size of computing devices, wireless sensor networks (WSNET) have the potential of being composed by an extremely large number of nodes offering multiple services. Such networks have the capability of executing multiple tasks concurrently by allocating simply a fraction of their resources. Alternatively, many smaller wireless networks may collaborate to e...

BACKGROUND Mandelic acid (MA), an important component in pharmaceutical syntheses, is currently produced exclusively via petrochemical processes. Growing concerns over the environment and fossil energy costs have inspired a quest to develop alternative routes to MA using renewable resources. Herein we report the first direct route to optically pure MA from glucose via genetic modification of th...

Method: This is a prospective, randomized, open trial study (from Iran) from September 2008 to September 2010, including 50 patients (25 patients in the combined imiquimod and cryotherapy group and 25 patients in the intralesional MA group). Patients were randomly assigned to receive combined cryotherapy biweekly with imiquimod three times per week or intralesional MA weekly until complete cure...

In December 2008, 8 in 10 rural Medicare beneficiaries had creditable prescription drug coverage, and over half of these beneficiaries were enrolled in a prescription drug coverage option offered through the Medicare Part D program (Figure 1). However, the array of coverage patterns for rural and urban beneficiaries is strikingly different. Rural beneficiaries are more likely to enroll in stand...

Approximations based on moment-closure (MA) are commonly used to obtain estimates of the mean molecule numbers and of the variance of fluctuations in the number of molecules of chemical systems. The advantage of this approach is that it can be far less computationally expensive than exact stochastic simulations of the chemical master equation. Here, we numerically study the conditions under whi...
