A clock for sending out electric signals once an hour or oftener

Timeline: Sending Out an SOS

development and implementation of an optimized control strategy for induction machine in an electric vehicle

in the area of automotive engineering there is a tendency to more electrification of power train. in this work control of an induction machine for the application of electric vehicle is investigated. through the changing operating point of the machine, adapting the rotor magnetization current seems to be useful to increase the machines efficiency. in the literature there are many approaches wh...

Sending signals dynamically.

Proteins mediate transmission of signals along intercellular and intracellular pathways and between the exterior and the interior of a cell. The dynamic properties of signaling proteins are crucial to their functions. We discuss emerging paradigms for the role of protein dynamics in signaling. A central tenet is that proteins fluctuate among many states on evolutionarily selected energy landsca...

Sending Out an SOS: Mitochondria as a Signaling Hub

Normal cellular physiology is critically dependent on numerous mitochondrial activities including energy conversion, cofactor and precursor metabolite synthesis, and regulation of ion and redox homeostasis. Advances in mitochondrial research during the last two decades provide solid evidence that these organelles are deeply integrated with the rest of the cell and multiple mechanisms are in pla...

A passage to India's HIV epidemics: sending out an SOS.

The official view is that India's epidemics are driven, directly and indirectly, by heterosexual prostitution. Review of available evidence by researchers in India undermines this weakly supported orthodoxy and suggests that correcting weaknesses in its AIDS surveillance system can lead to a more reliable picture of HIV propagation and hence to evidence-based interventions. Contenders for leadi...
