background: surface electromyography (semg) of muscles is a non-invasive tool that can be helpful in the assessment of muscle function and some motor control evaluations. a loss of force, known as muscle fatigue is accompanied by changes in muscle electrical activity. one of the most commonly used surface emg parameters which reflects paraspinal muscle fatigue during different tasks and positio...

The first crystal structure of  [Cu(terpy)2](PF6 )2 , where terpy=2,2':6',2"-terpyridine is reported. Green crystals of  [Cu(terpy)2](PF6 )2 were grown by ether diffusion into an acetonitrile solution of the complex. Crystal structure of this complex is tetragonal ( space group: P21c ...

Garrison and Wright showed that upon undergoing cyclic quantum evolution a meta-stable state acquires both a geometric phase and a geometric decay probability. This is described by a complex geometric “phase” associated with the cyclic evolution of two states and is closely related to the two state formalism developed by Aharonov et al.. Applications of the complex geometric phase to the Born–O...

The L-arabinose operon in Escherichia coli is a model system for the study of the control of gene expression. Maximal expression of the araBAD operon requires two positive control components: the araC protein-L-arabinose complex and the cyclic AMP receptor protein-cyclic AMP complex. Both araC protein and cyclic AMP receptor protein are required for the initiation of transcription of araBAD mRN...
