JAPAN ARCHITECTURAL REVIEW, Volume 8, Issue 1, January–December 2025.ABSTRACT Super‐high‐rise buildings commonly utilize tuned mass dampers (TMDs) for vibration control. However, buildings with different natural periods in two horizontal directions typically require multiple TMDs, increasing weight, and costs. In this study, a bidirectional TMD (BTMD) was developed to control vibrations simultaneously in both horizontal

Capsule release surgery temporarily reduces contracture in a rat elbow model of arthrofibrosis
Journal of Orthopaedic Research, Volume 43, Issue 1, Page 23-36, January 2025.Abstract Elbow trauma can lead to joint contracture and reduced range of motion (ROM). Nonsurgical interventions can improve ROM, but in some cases capsule release surgery is required. Although surgery can improve ROM, it often does not restore full ROM. Thus, alternatives are needed.
