Autonomous Hydrogel Actuators Programmed by Endogenous Biochemical Logic for Dual‐Stage Morphing and Drug Release

open access: yesAdvanced Materials, EarlyView.
A 3D‐printed BSA–PEGDA bilayer actuator performs biochemical logic, bending autonomously in acid and releasing its drug payload only when both acid and pepsin are present. This dual‐stage, enzyme‐gated mechanism enables autonomous catch‐and‐release motion and controlled gastric drug delivery, representing a programmable soft material powered by ...

Recreational and Angler Survey of the Buffalo National River, Arkansas [PDF]

open access: yes, 1995
The Buffalo River in northern Arkansas was surveyed for recreator and angler use in 1991 and 1992. The river was divided into three reaches and numbers of boats, recreators, anglers, and catches were compiled by creel clerks at nine selected take-out ...

Label‐Free Sensing of Coronaviral Sequences via Kretschmann‐Configuration Reflectance Spectroscopic Ellipsometry: Sensitivity, Specificity, and Interfacial Effects

open access: yesAdvanced Materials Interfaces, EarlyView.
Spectroscopic ellipsometry in the Kretschmann‐Raether configuration (KRSE) is employed to characterize a DNA‐functionalized platform for viral sequence recognition. By merging SE with surface plasmon resonance, KRSE outperforms conventional SE, achieving nanomolar targeting through resonance wavelength shifts (δλ) measurements. Its enhanced interfacial

Catch and release of propagating bosonic field with non-Markovian giant atom

open access: yesNew Journal of Physics
The non-Markovianity of physical systems is considered to be a valuable resource that has potential applications to quantum information processing. The control of traveling quantum fields encoded with information (flying qubit) is crucial for quantum ...

Longline-caught blue shark (Prionace glauca): factors affecting the numbers available for live release* [PDF]

open access: yes, 2005
The blue shark (Prionace glauca) is an oceanic species that occurs in temperate and tropical waters around the globe (Robins and Ray, 1986). This species is a major bycatch of pelagic longline fleets that operate to supply the world’s growing demand for

Terahertz Volume Plasmon‐Polariton Modulation in All‐Dielectric Hyperbolic Metamaterials

open access: yesAdvanced Optical Materials, EarlyView.
THz volume plasmon‐polariton (VPP) propagation through plasmon‐based hyperbolic metamaterials, made of alternating layers of doped and undoped III‐V semiconductors. Abstract The development of plasmonics and related applications in the terahertz range faces limitations due to the intrinsic high electron density of the standard metals.

Inverse‐Designed on‐Chip Terahertz Three‐Channel Mode and Wavelength Division Demultiplexer

open access: yesAdvanced Photonics Research, EarlyView.
An ultracompact terahertz demultiplexer is developed using a hybrid inverse design that combines genetic algorithms with topology optimization. The device enables simultaneous mode‐ and wavelength‐division multiplexing within a footprint smaller than two wavelengths.
