Shear‐Isolating Actuation System for Exosuit Using Movable Pulley With Webbing‐Driven Mechanism
Advanced Robotics Research, EarlyView.Tendon‐driven exosuits can chafe the skin because the moving tendon slides against the wearer. A shear‐isolating actuation system combining a movable pulley with flat‐profile webbing keeps the body‐contacting tendon layer stationary, relocating relative motion away from the skin. The compact 145‐g actuator delivers 150 N of assistance, and benchtop and

Helix Alignment, Chevrons, and Edge Dislocations in Twist‐Bend Ferroelectric Nematics
Advanced Science, EarlyView.The recently discovered twist‐bend ferroelectric nematic (NTBF) is the new member of the multiferroic family, representing a fluid with an oblique helicoidal (heliconical) periodic structure of spontaneous electric polarization. The work presents a thorough exploration of the material properties of this phase, how the periodic modulation of ...

Advanced Science, EarlyView.This study combines full‐field tomography with diffraction mapping to quantify radial (ε002$\varepsilon _{002}$) and axial (ε100$\varepsilon _{100}$) lattice strain in wrinkled carbon‐fiber specimens for the first time. Radial microstrain gradients (−14.5 µεMPa$\varepsilon \mathrm{MPa}$−1) are found to signal damage‐prone zones ahead of failure, which ...

Impact of real and nominal factors on long run equilibrium in Real Effective Exchange Rate (REER) in Pakistan [PDF]
In this paper, we focused on the hypothesis that nominal shocks such as monetary policy have only temporary impact on long run equilibrium real exchange rate and the consequent misalignment. To do so we utilized two approaches to tackle this issue.

Wind Turbine Generator Reliability: An Exploration of the Root Causes of Generator Bearing Failures [PDF]
, 2013 Increasing the availability of multi-megawatt wind turbines (WT) is necessary if the cost of energy generated by wind is to be reduced. Reliability surveys have shown that WT generator bearings have a relatively high failure rate, with failures happening

Organoid Brain‐Machine‐Interface Devices for Central Nervous System Repair
Advanced Science, EarlyView.We envision organoid brain‐machine‐interface (Organoid‐BMI) devices as new biohybrid bidirectional communication pathways to connect the human CNS and the external world for personalized CNS repair and regeneration. ABSTRACT Central nervous system (CNS) repair and regeneration suffer from tremendous clinical challenges due to current limitations in ...

Automated Extraction of Multicomponent Alloy Data Using Large Language Models for Sustainable Design
Advanced Science, EarlyView.A large language model (LLM) based pipeline is developed to automatically extract a comprehensive and accurate multicomponent alloy database from literature corpus. The extracted dataset is integrated with sustainability indicators to identify potential alloys that outperform existing industrial benchmark materials in terms of both performance and ...

Yuan Real Exchange Rate Undervaluation, 1997-2006. How Much, How Often? Not Much, Not Often [PDF]
Yuan real effective exchange rate misalignment is esitimated in a behavioral equilibrium exchange rate (BEER) model for the period 1997 to third quarter 2007. Using the Beveridge-Nelson decomposition a vector error correction model (VECM) of the exchange
