Rotary Electromechanical System Integrating Non‐Reciprocal Memory and Combinational Logic
Advanced Science, EarlyView.Rotational bistability, interfaced through a conductive network with switchable contacts, unifies logic operations and mechanical memory within a rotary electromechanical system. The author demonstrates how serially coupled configurations of rotationally bistable modules enable reprogrammable sequential logic governed by mechanical state transition and

Rotor instability due to a gear coupling connected to a bearingless sun wheel of a planetary gear [PDF]
A 21 MW electric power generating unit comprises a gas turbine, a planetary gear, and a generator connected together by gear couplings. For simplicity of the design and high performance the pinion of the gear has no bearing.

Rapid Design and Fabrication of Body Conformable Surfaces with Kirigami Cutting and Machine Learning
Advanced Science, EarlyView.By integrating the principles of kirigami cutting and data‐driven modeling, this study aims to develop a personalized, rapid, and low‐cost design and fabrication pipeline for creating body‐conformable surfaces around the knee joint. This pipeline presents a balanced trade‐off between conformability performance and cost for personalizing wearables, thus

Did the Indian Green Revolution Change the Farm Size–Productivity Relationship?
Applied Economic Perspectives and Policy, EarlyView.ABSTRACT We examine the relationship between farm size and productivity during India's Green Revolution, a period of rapid technological transformation. Using a unique panel of over 5000 Indian farm households that spans the Green Revolution (1971–1999), we show that the classic (linear) inverse farm size–productivity relationship gradually evolved ...
