Ability to categorize end-feel joint movement according to years of clinical experience: an experiment with an end-feel simulator.

[Purpose] Discrimination between end-feel types is difficult, and years of clinical experience is considered a factor for improving the accuracy of the discrimination. The present study investigated whether the accuracy of classification of end-feel types improves with the increase in years of clinical experience. [Participants and Methods] In total, 44 therapists (range of years of clinical experience: 1-26 years) and 13 students were included.

Evolution of Superconductivity with Sr-Deficiency in Antiperovskite Oxide SrSnO.

Bulk superconductivity was recently reported in the antiperovskite oxide SrSnO, with a possibility of hosting topological superconductivity. We investigated the evolution of superconducting properties such as the transition temperature T and the size of the diamagnetic signal, as well as normal-state electronic and crystalline properties, with varying the nominal Sr deficiency x. Polycrystalline SrSnO was obtained up to x = 0:6 with a small amount of SrO impurities.

Robotic finger perturbation training improves finger postural steadiness and hand dexterity.

The purpose of the study was to understand the effect of robotic finger perturbation training on steadiness in finger posture and hand dexterity in healthy young adults. A mobile robotic finger training system was designed to have the functions of high-speed mechanical response, two degrees of freedom, and adjustable loading amplitude and direction. Healthy young adults were assigned to one of the three groups: random perturbation training (RPT), constant force training (CFT), and control.

Superconductivity in the antiperovskite Dirac-metal oxide SrSnO.

Investigations of perovskite oxides triggered by the discovery of high-temperature and unconventional superconductors have had crucial roles in stimulating and guiding the development of modern condensed-matter physics. Antiperovskite oxides are charge-inverted counterpart materials to perovskite oxides, with unusual negative ionic states of a constituent metal. No superconductivity was reported among the antiperovskite oxides so far.

Biomechanical analysis of subjective pinching effort based on tendon-skeletal model.

In this paper, the influence of the finger posture on the subjective effort during pinching motion is investigated by using a tendon-skeletal finger model. The experimental results show that the subjective effort human feels is affected by the size of the object he/she pinches, and the subjective effort correlates with the finger length. The simulation results show that the pattern of the tendon forces is similar to that of the EMG activity measured in the experiment, and the positive correlation was observed between the finger length and the object size where the summation of the tendon forces becomes the minimum.
