Business Strategy and the Environment, EarlyView.ABSTRACT Adopting a signaling perspective, this study examines whether corporate green patenting reduces the cost of equity by mitigating information asymmetry in capital markets. Using longitudinal panel data from South Korea, we find that green patenting—encapsulating technological innovation related to energy, environmental protection, and climate ...

Making Two out of One: Kinesin Motors Driving Plant Cell Division
Cytoskeleton, EarlyView.ABSTRACT The Kinesin superfamily of microtubule dependent motors is present in all eukaryotes. Not all of the subfamilies are represented in all kingdoms, and the ones that are do not always show conserved functions. Tight control of the cytoskeleton is essential for proper progression and completion of mitosis and cytokinesis, and key functions are ...

Effect of Pre-strain and Pre-corrosion on Ratcheting Behavior of ASTM A668 Class D Steel [PDF]
, 2016 Ratcheting can be considered as one of the serious problems as this phenomenon causes premature failure of structural components. Ratcheting deformation can be regarded as the stress controlled low cycle fatigue (LCF) response of a material which occurs ...

Photoreversible Polyurea Actuators With Spatiotemporal Control and Adaptive Mechanics
ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.A light–thermal responsive polyurea network incorporating reversibly dimerizable anthracene units enables spatiotemporal modulation of cross‐linking density and nearly 400‐fold stiffness tuning. Integrating programmable anisotropy, photopatterning, self‐healing, and photowelding within a single framework, this bioinspired “one network–multifunction ...

Micromechanical investigation of soil plasticity using a discrete model of polygonal particles [PDF]
Theoretical and Applied Mechanics, 2008 The mechanical behavior of soils has been traditionally described using continuum-mechanics-based models. These are empirical relations based on laboratory tests of soil specimens.

Absence seizures: Update on signaling mechanisms and networks
Epilepsia Open, EarlyView.Abstract Absence seizures (AS) are a hallmark of genetic generalized epilepsies (GGE), characterized by brief episodes of impaired consciousness accompanied by electroencephalographic spike‐and‐wave discharges (SWDs). Traditionally attributed to cortico‐thalamo‐cortical (CTC) dysrhythmia, emerging evidence suggests a more intricate pathophysiological ...
