State‐of‐the‐Art Solar Blind and X‐Ray Photodetectors Based on Gallium Oxide

open access: yesAdvanced Photonics Research, EarlyView.
State‐of‐the‐art Ga2O3‐based solar‐blind UV and X‐ray photodetectors (PDs) are reviewed. Benchmark plots compare responsivity versus specific detectivity for UV PDs (photoconductors, photovoltaic, Schottky, heterojunction, avalanche, and phototransistor types) and sensitivity versus response time for X‐ray detectors based on Ga2O3 bulk crystals, thin ...

Ultrashort‐Pulsed Laser Diffusion Enhancement in Liquids for Cold Extraction of Coffee in an Analytically Validated Low‐Fluence Regime

open access: yesAdvanced Photonics Research, EarlyView.
In this article, pulsed laser diffusion enhancement in liquids as an analytically validated laser extraction in liquids method of coffee suspensions in a defined low fluence window is presented. The results confirm the generation of a unique aroma profile and reduced acidity, which is neither attributed to changes in the specific surface area nor ...

Self‐Aligned Pillar Arrays Embedding Site‐Controlled Single Quantum Dots for Bright Nonclassical Light Emission

open access: yesAdvanced Photonics Research, EarlyView.
Tilted‐view scanning electron microscope images show arrays of self‐aligned etched GaAs triangular pillars hosting single quantum dots. The main image captures the as‐fabricated morphology prior to dielectric coating, highlighting their uniform geometry.

Continuity of metric projections in uniformly convex and uniformly smooth Banach spaces

open access: yesJournal of Approximation Theory, 1983
The continuity of the metric projection onto an approximately compact set in a uniformly convex and uniformly smooth Banach space is investigated. The concept of directional radius of curvature at a point is defined: this allows the author to obtain an explicit modulus of continuity for the metric projection onto some sets (which are not necessarily ...

Impact of System‐Model Mismatch in Fourier Ptychographic Microscopy

open access: yesAdvanced Photonics Research, EarlyView.
This study investigates the robustness of Fourier ptychography microscope (FPM) reconstruction algorithms across various scenarios, each representing challenges encountered in practical FPM experiments, and deduces the extent to which FPM can provide diffraction‐limited resolution under the influence of various sources of error.

Learning Highly Dynamic Skills Transition for Quadruped Jumping Through Constrained Space

open access: yesAdvanced Robotics Research, EarlyView.
A quadruped robot masters dynamic jumps through constrained spaces with animal‐inspired moves and intelligent vision control. This hierarchical learning approach combines imitation of biological agility with real‐time trajectory planning. Although legged animals are capable of performing explosive motions while traversing confined spaces, replicating ...

Inflatable Kirigami Crawlers

open access: yesAdvanced Robotics Research, EarlyView.
Inflatable kirigami crawlers are fabricated from heat‐sealable textiles and achieve motion through cyclic pneumatic actuation. Strategically placed kirigami cuts guide asymmetric deformation, doubling contraction compared to traditional pouches and forming scale‐like surfaces.
