Confinement‐Induced Donnan Potential Enables Sealed Hydrovoltaic Power From Microliter Water

Advanced Materials, EarlyView.
An ultrathin MXene/cellulose nanofiber (CNF) nanochannel‐based hydrovoltaic generator produces sustained direct current (DC) from a single microliter droplet under sealed operation. Asymmetric nanochannel confinement establishes a persistent ion gradient and a confinement‐induced Donnan potential, harvesting the interfacial free energy released upon ...

Fixed k-watchman routes under the Min-Max criterion in staircase polygons [PDF]

AUT Journal of Mathematics and Computing
In this paper, the problem of multiple watchman routes in staircase polygons is studied. The watchman route problem (WRP) is a variation of the art gallery problem (AGP) in computational geometry, where each point in the given polygon must be visible ...

Less Is More: Management of Left Atrial Appendage Perforation With Impending Cardiac Tamponade Following Watchman Device Placement

Case Reports in Cardiology
By 2030, the United States will have over 12 million people with atrial fibrillation, which carries a five-fold increase in risk of stroke. Watchman device is an alternative in patients who are poor candidates for anticoagulation. Here, we present a rare

The Future of Research in Cognitive Robotics: Foundation Models or Developmental Cognitive Models?

Advanced Robotics Research, EarlyView.
Research in cognitive robotics founded on principles of developmental psychology and enactive cognitive science would yield what we seek in autonomous robots: the ability to perceive its environment, learn from experience, anticipate the outcome of events, act to pursue goals, and adapt to changing circumstances without resorting to training with ...
