Multilevel converters offer advantages in terms of the output waveform quality due to the increased number of levels used in the output voltage modulation. This advantage is particularly true for cascade H-bridge (CHB) converters that can be built to produce a large number of levels owing to their modular structure. When increase the number of levels it requires more number of switches, it impl...

Genetic vaccines offer a treatment opportunity based upon successful gene delivery to specific immune cell modulators. Driving the process is the vector chosen for gene cargo packaging and subsequent delivery to antigen-presenting cells (APCs) capable of triggering an immune cascade. As such, the delivery process must successfully navigate a series of requirements and obstacles associated with ...

The abilities of a series of six mutants of the human insulin receptor, an insulin receptor/v-ros hybrid (IR-ros) and the P68gag-ros transforming protein to stimulate S6 protein kinase have been assessed. Insulin receptor mutants in which either 1 or 2 tyrosine residues have been replaced with phenylalanine (YF1, YF3) have lost some or all of the capacity to mediate the activation of S6 kinase ...

Humans share a universal and fundamental set of emotions which are exhibited through consistent facial expressions. An algorithm that performs detection, extraction, and evaluation of these facial expressions will allow for automatic recognition of human emotion in images and videos. Presented here is a hybrid feature extraction and facial expression recognition method that utilizes Viola-Jones...
