Water‐to‐Air Imaging: A Recovery Method for the Instantaneous Distorted Image Based on Structured Light and Local Approximate Registration

Engineering Reports, Volume 7, Issue 4, April 2025.
This paper proposed a new restoration method for instantaneous images distorted by a wavy water surface. It can effectively eliminate the refraction distortions and improve the visual effect of the image. This means that our method can be applied to a wider range of practical scenarios, especially for dynamic target detection.

Indirect epicardial targeting of left atrial tachycardia using Bachmann's bundle: A case report of successful ablation from pulmonary artery

Journal of Arrhythmia, Volume 41, Issue 2, April 2025.
Successful rhythm control by standard endocardial methods may become quite challenging in some atrial tachycardia cases, very few of which may need extraordinarily different approaches after the initial failure of extensive endocardial ablation, such as epicardial ablation after subxiphoid puncture, or venous alcohol injection inside the vein of ...

Abnormal Unidirectional Lasing from the Combined Effect of non‐Hermitian Modulated Bound States in the Continuum and Fabry–Pérot Resonance

Laser &Photonics Reviews, Volume 19, Issue 7, April 4, 2025.
A parity‐time (PT) symmetry grating results in an asymmetric split of bound states in the continuum (BIC). Based on the joint effect of the asymmetric PT‐BICs and cavity resonance, a line source produces unidirectional and single mode lasing with an interesting wavefront transformation: from a diverging wave to a unidirectional plane wave.

Maskless Synthesis of van der Waals Heterostructure Arrays Engineered for Light Harvesting on Large Area Templates

Small, Volume 21, Issue 15, April 16, 2025.
Large area fabrication of few‐layer MoS2‐WS2 vertical heterostructures nanoarrays over periodically nanostructured silica templates is demonstrated by means of a custom‐made physical deposition set‐up. The optical anomalies arising from subwavelength periodicity and the engraved WS2 nanostripes acting as optical sensitizers result in broadband and ...

Were Gravity Waves or Lamb Waves Responsible for the Large‐Scale Thermospheric Response to the Tonga Eruption?

AGU Advances, Volume 6, Issue 2, April 2025.
Abstract The extraordinary eruption of the Tonga volcano on 15 January 2022 lofted material to heights exceeding 50 km, marking the highest observed since the satellite era. This eruption caused significant disturbances spanning from the hydrosphere up to the thermosphere.
