Resolving the environmental factors that determine pond thermal refuge quality

open access: yesLimnology and Oceanography Letters, EarlyView.
Abstract Cold thermal refuges may mitigate detrimental effects of future climate warming; yet, pond ecosystems have been largely omitted from thermal refuge research despite being globally numerous and providing critical ecosystem services. We create a formal definition for pond thermal refuge quality, then operationalize this definition by measuring ...

Integrated RF Photonic Front‐End Capable of Simultaneous Cascaded Functions

open access: yesLaser &Photonics Reviews, EarlyView.
An integrated programmable RF photonic front‐end capable of simultaneous cascaded functions is demonstrated, including notch filtering with true time delay or phase shifting. This work shows the feasibility to achieve cascaded functions within an integrated RF photonic front‐end.

Multi‐Octave All‐Dielectric Directional Coupler Using Integrated Half‐Mirror for Ultrawideband Terahertz Systems

open access: yesLaser &Photonics Reviews, EarlyView.
Fully exploiting the broad untapped terahertz spectrum necessitates extending the bandwidth of practical guided‐wave systems. This work introduces a substrateless quasi‐optical integration platform to meet this need. Classical optical principles going back to the time of Michelson are adapted to a planar, micro‐machined, monolithic‐silicon platform ...

Direct Lithography for Regulating Multiple Properties of Organic Semiconductors via Photo‐Crosslinkers

open access: yesMacromolecular Materials and Engineering, EarlyView.
The technique of patterning polymers using photo‐crosslinkers has attracted considerable attention in organic electronics. Owing to the retention of photo‐crosslinkers in the blended films after development, various properties of the films will be affected.

Computer Vision Technologies in Movement Disorders: A Systematic Review

open access: yesMovement Disorders Clinical Practice, EarlyView.
Abstract Background Evaluation of movement disorders primarily relies on phenomenology. Despite refinements in diagnostic criteria, the accuracy remains suboptimal. Such a gap may be bridged by machine learning and video technology, which permit objective, quantitative, non‐invasive motor analysis.
