Background: Stroke patients often experience alterations in their subjective feeling of ownership for the affected limb, which can hinder motor function and interfere with rehabilitation. In this study, we aimed at disentangling the complex relationship between sensory impairment, body ownership (BO), and motor control in stroke patients.

Methods: We recruited 20 stroke patients with unilateral upper limb sensory deficits and 35 age-matched controls.

Article Synopsis
  • The study observes the melting of a vortex lattice in a rapidly rotating quasi-two-dimensional Bose gas due to thermal fluctuations.
  • Researchers analyzed vortex positions and lattice order using specific correlation functions after a time-of-flight expansion, varying the rotation frequency while keeping atom number and temperature constant.
  • The results indicate a melting transition, evidenced by changes in orientational correlations linked to an increase in dislocations, aligning with established theories of two-dimensional melting.

Particles trapped at a fluid-fluid interface by capillary forces can form a monolayer that jams and buckles when subject to uniaxial compression. Here we investigate experimentally the buckling mechanics of monolayers of millimeter-sized rigid plates trapped at a planar fluid-fluid interface subject to uniaxial compression in a Langmuir trough. We quantified the buckling wavelength and the associated force on the trough barriers as a function of the degree of compression.
