Using the random matrix theory we demonstrate explicitly the insensitivity of the transverse force on a moving vortex to non-intrinsic and non-magnetic impurities in a superconductor. The Berry phase acquired by a moving vortex suggests that the total transverse force on a moving vortex is proportional to the superfluid density at zero temperature, irrespective whether or not impurities are pre...

Women Social Security Beneficiaries Aged 62 or Older, 196~85* During the past half century, the number of women in the labor force has increased at a substantially higher rate than the number of working age women (table 1). In 1930, 10 million women workers represented only 24 percent of all women and 22 percent of the total labor force. By 1955, the number of women workers had doubled and wome...

In lattice models, local pressure on a surface is derived from the change in the free energy of the system due to the exclusion of a certain boundary site, while the total force on the surface can be obtained by a similar exclusion of all surface sites. In these definitions, while the total force on the surface of a lattice system matches the force measured in a continuous system, the local pre...

OBJECTIVE Interlimb coupling between impaired and non-impaired limbs after stroke has been a common observation. The aim of this study was to examine interlimb interactions in force production in responses to altered visual gain in hemiparetic stroke survivors. DESIGN prospective clinical study METHODS A convenient sample of 7 hemiparetic stroke subjects (3 women and 4 men; mean age 56.0 ye...

We present and numerically solve a modified form of the equation of motion for a charged particle under the influence of an external force, taking into account the radiation reaction. This covariant equation is integro-differential, as Dirac-Röhrlich's, but has several technical improvements. First, the equation has the form of Newton's second law, with acceleration isolated on the left hand si...

This final overarching study in a series documents research and recommendations RAND offered to the Air Force to help strengthen the development of a new office responsible for monitoring and promoting resilience among Air Force Airmen, civilian employees, and Air Force families. Efforts to boost resilience have become an important military response to suicide and other markers of distress and ...

Neurovascular muscle transfer restores functional loss from injury or disease but a significant muscle force deficit results. This work determined whether atrophy and denervated muscle fibers account for this force deficit. The proximal and distal extensor digitorum longus (EDL) muscle tendons were transected and immediately repaired in a rat neurovascular muscle transfer model. The peroneal ne...
