Design and Modeling of a High‐Displacement, Skin‐Integrated Flexible Electromagnetic Actuator for Haptic Interfaces in Virtual Reality

Advanced Robotics Research, EarlyView.
A flexible, skin‐integrated electromagnetic actuator is developed for wearable virtual/augmented reality (VR/AR) haptic systems. A tunable design model enables control over displacement and resonance frequency. The system is validated through a custom VR application with a 6 × 4 actuator array, demonstrating real‐time, spatially targeted tactile ...

Integrating Peak Ground Acceleration as a Damage Factor in Risk-Based Premium Rate Assessment using K-medoids Bayesian networks

Journal of Applied Science and Engineering
In the insurance market, determining fair and acceptable premium rates requires an accurate evaluation of risk. In the context of earthquake damage, the Peak Ground Acceleration (PGA) level is essential for assessing the intensity of ground shaking and ...

Agricultural insurance and risk management among poultry farmers in Ghana: An application of discrete choice experiment

Journal of Agriculture and Food Research, 2023
Risks, risk management techniques and the willingness to insure poultry farms by poultry farmers in Ghana were explored. Random Parameter Logit (RPL) and Conditional Logit (CL) models were used for the analysis.

Broadening Hard‐Magnet Discovery Beyond Symmetry Constraints via Unified Effective Anisotropy

Advanced Science, EarlyView.
A unified effective‐anisotropy descriptor (Keff) extends hard‐magnet screening across all seven crystal systems, beyond the uniaxial restriction of conventional searches. Machine‐learning screening of 9320 known ferromagnets and diffusion‐model generation together yield 38 rare‐earth‐free or ‐lean candidates with DFT‐validated magnetic hardness (κ > 1),

Risk management and the credit risk premium [PDF]

Journal of Banking & Finance, 2001
Firms use a variety of different strategies to manage financial risks. This is the case even among firms that face practically identical risk exposures, such as gold mining corporations. This paper develops a theoretical model to show that this diversity can be explained by differences in firms' credit risk premia.

Repurposing a Small Molecule Plant Hormone as a Tunable ON‐Switch for CAR‐T Cell Immunotherapy

Advanced Science, EarlyView.
By engineering a receptor system integrating the plant auxin receptor AFB1 with its co‐receptor IAA7, we enable ligand‐dependent interactions triggered by the plant hormone auxins. This design allows rapid, reversible, and dose‐dependent T cell activation, resulting in potent cytotoxicity against B‐cell lymphoma in vitro and in vivo.

Uncertainty in Pricing and Risk Measurement of Survivor Contracts

Risks
As life expectancy increases, pension plans face growing longevity risk. Standardized longevity-linked securities such as survivor contracts allow pension plans to transfer this risk to capital markets.

The Fundamental Equity Premium and Ambiguity Aversion in an International Context

Risks, 2018
Stocks are riskier than bonds. This causes a risk premium for stocks. That the size of this premium, however, seems to be larger than risk aversion alone can explain the so-called “equity premium puzzle”.

Deep Learning‐Driven Discovery and Engineering of an Efficient PETase for Depolymerization and Detoxification of PET Microplastics Under Physiological Conditions

Advanced Science, EarlyView.
A deep learning–driven pipeline mining 246 million protein sequences uncovers AhPETase, an evolutionarily distinct PET hydrolase. Engineered variant AhPETaseM1 degrades post‐consumer PET microplastics under physiological conditions and reverses microplasticinduced cytotoxicity in human lung and colon cells, establishing enzymatic microplastic ...
