Transient Laser‐Induced Periodic Surface Structures Revealed by Time‐Resolved EUV Diffuse Scattering

open access: yesLaser &Photonics Reviews, EarlyView.
The study shows that femtosecond laser pulses generate transient, LIPSS‐like surface patterns at fluences far below the damage threshold. Time‐resolved extreme ultraviolet scattering captures reciprocal space features that form within a few picoseconds and vanish on sub‐nanosecond timescales.

Development and Evaluation of a Low‐Cost, Semi‐Automated Camera Trap for Surveying Bumble Bee Communities

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
Camera traps are emerging as a useful tool for noninvasive insect monitoring; however, it remains unclear how to lure diurnal insects to traps, how to detect them upon arrival, and how camera‐based methods compare to conventional sampling. We developed a low‐cost, open‐source camera trap to monitor wild bumble bees in agricultural fields. We found that

Concrete in architecture: Redefining form, space, function, and insights from bibliometric analysis

open access: yesStructural Concrete, EarlyView.
Abstract Concrete has become a cornerstone in architectural and engineering innovation, as it seamlessly integrates structural performance with artistic expression. Its evolution from ancient opus caementicium to contemporary ultra‐high‐performance concrete illustrates its adaptability to the change in technological, environmental, and design paradigms.

A novel seismic connector for precast concrete shear walls

open access: yesStructural Concrete, EarlyView.
Abstract A critical aspect of the seismic performance of precast concrete walls is the deformation capacity of their connections, which can be limited by premature bar fracture, reinforcement buckling, or cyclic instability. This paper introduces and experimentally validates a new ultra‐ductile connector (UltraDC) that provides reliable force transfer ...

Life Under the Snow: Camera Trap Videos Capture Year‐Round Lemming Activity and Behavior

open access: yesIntegrative Zoology, EarlyView.
We developed an automated camera system capable of recording year‐round videos of lemmings beneath the snow in the High Arctic. We demonstrate the potential of this system to document lemming activity and behaviors. Our results show that it effectively monitors lemming relative abundance with temporal precision unmatched by other methods.

A development of a corrugated roof tile solar panel

open access: yesJapanese Journal of Applied Physics
Abstract The main objective of this work is to develop a corrugated roof tile solar panel for installation together with ordinary corrugated roof tiles in Thailand. The roof tile solar panel was designed to resemble the external size and shape of ordinary corrugated roof tiles, with laminated monocrystalline silicon solar cells inside ...

Disentangling atmospheric and soil drought: a new stand‐level manipulation approach for mature forests

open access: yesNew Phytologist, EarlyView.
Design of the VPDrought experiment in a Scots pine (Pinus sylvestris) forest at the Pfynwald research platform. Summary Atmospheric and soil drought are major, yet typically confounded, drivers of tree stress. Rising vapor pressure deficit (VPD) may impair forest function independently of soil moisture decline, yet stand‐scale experimental separation ...
