A little bit of sex matters for genome evolution in asexual plants
Frontiers in Plant Science, 2015 Genome evolution in asexual organisms is theoretically expected to be shaped by various factors:first, hybrid origin and polyploidy confer a genomic constitution of highly heterozygous genotypes with multiple copies of genes;second, asexuality confers a ...

Ratchet effect in dc SQUIDs [PDF]
Europhysics Letters (EPL), 2000 We analyzed voltage rectification for dc SQUIDs biased with ac current with zero mean value. We demonstrate that the reflection symmetry in the 2-dimensional SQUID potential is broken by an applied flux and with appropriate asymmetries in the dc SQUID.

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 ...

Conceptualizing Corporate Political Activity for Sustainability Governance—The CPA Cube
Business Strategy and the Environment, EarlyView.ABSTRACT Sustainability transformations in the economy, and related public policy decisions, are highly contested, attracting business involvement. To better understand how business influence on government impacts the success or failure of sustainability governance efforts, this paper extends the literature on corporate political activity (CPA) by ...

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 ...

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 ...

Climate Driven Water Table Changes and Their Influence on Liquefaction Response of Integral Bridges
Earthquake Engineering &Structural Dynamics, EarlyView.ABSTRACT Integral abutment bridges (IABs) eliminate bearings and joints but transfer seismic demand directly into the surrounding soil, making their response highly sensitive to groundwater conditions and soil–structure interaction. This study presents a 60 g centrifuge testing programme on single‐span IABs designed to isolate the influence of water ...

Synergy between RecBCD subunits is essential for efficient DNA unwinding
eLife, 2019 The subunits of the bacterial RecBCD act in coordination, rapidly and processively unwinding DNA at the site of a double strand break. RecBCD is able to displace DNA-binding proteins, suggesting that it generates high forces, but the specific role of ...

Use of ultrasonography in assessing peri‐implant osseous defects: An in vitro study
Journal of Periodontology, EarlyView.Abstract Background The purpose of this study is to investigate the feasibility and diagnostic accuracy of ultrasonography in peri‐implant defect identification and evaluation, and to compare ultrasonography (USG) with cone‐beam computed tomography (CBCT) in defect identification and evaluation in an in vitro model.
