A unified expression for topological invariants has been proposed recently to describe the order in Dirac models belonging any dimension and symmetry class. We uncover a correspondence between curvature function that integrates this invariant quantum metric measures distance properly defined many-body Bloch states momentum space. Based on metric-curvature correspondence, time-resolved angle-res...

Background Spinal deviations usually refer to abnormal lateral or sagittal curvature that could be the cause or effect of some spinal diseases. The conventional orthotic intervention is to apply passive forces to a patient's body with an orthosis for supporting and controlling the trunk alignments. However, once the orthosis is removed, such functions cannot be maintained. Therefore, an active ...

Spinal deformities have been evaluated in a five year retrospective study where 28 boys and 25 girls all having Friedreich's ataxia were on the average assessed once a year in a multidisciplinary clinic. Scoliosis seems somewhat more progressive in girls than in boys and more severe in non-ambulatory than ambulatory patients. Some of those scolioses are very progressive reaching 60 degrees to 1...

STUDY DESIGN Experimental study of a localized device for the control of the vertebral growth using an immature porcine model. OBJECTIVE The aim of the study was to experimentally evaluate a localized device acting on the epiphyseal growth plates without bridging the intervertebral disc of immature hybrid pigs over 3 months of growth. SUMMARY OF BACKGROUND DATA Based on current published li...

ABSTRACT The parabolic structure of the secondary or conjugate spectra pulsars is often result isolated one-dimensional (or at least highly anisotropic) lenses in interstellar medium (ISM). curvature these features contains information about velocities Earth, ISM, and pulsar along primary axis lens. As a result, measuring variations over course year, orbital period for binaries, can constrain p...
