Multispectral Photonic Structural Colors via Enhanced Interfacial Interference of Ultrathin Cellulose Nanofiber/MXene Films

Advanced Science, EarlyView.
Fabrication of CNF‐MXene free‐standing films: Ti3C2Tx MXene flakes integrated into a cellulose nanofiber (CNF) matrix through layered self‐assembly using vacuum‐assisted filtration. The layered structure of 4 µm thickness is displayed on SEM image.

The Attachment Process of Negative Connecting Leader to the Lateral Surface of Downward Positive Leader in a Positive Cloud‐To‐Ground Lightning Flash

Geophysical Research Letters, 2023
Using high‐speed video cameras operating with framing rates of 20 and 50 kiloframes per second, we captured an attachment process during a positive cloud‐to‐ground flash, which demonstrates the connection of the negative connecting leader (NCL) to the ...

Methionine Metabolism Dictates PCSK9 Expression and Antitumor Potency of PD‐1 Blockade in MSS Colorectal Cancer

Advanced Science, EarlyView.
xxxx. Abstract Nutrient metabolisms are vitally interrelated to cancer progression and immunotherapy. However, the mechanisms by which nutrient metabolisms interact to remodel immune surveillance within the tumor microenvironment remain largely unexplored.

Spatial Variation of the Correlated Color Temperature of Lightning Channel [PDF]

arXiv, 2014
In present work, we propose the analysis method of lightning based on the color analysis. We analyzed the digital still images in which the cloud-to-ground (CG) and intracloud (IC) lightning flashes are shown. Applying some digital image processing techniques, we extracted lightning channels.

Identifying Lightning Processes in ERA5 Soundings with Deep Learning [PDF]

arXiv, 2022
Atmospheric environments favorable for lightning and convection are commonly represented by proxies or parameterizations based on expert knowledge such as CAPE, wind shears, charge separation, or combinations thereof. Recent developments in the field of machine learning, high resolution reanalyses, and accurate lightning observations open possibilities

The climate impact of aerosols on the lightning flash rate: is it detectable from long-term measurements?

Atmospheric Chemistry and Physics, 2018
. The effect of aerosols on lightning has been noted in many case studies, but much less is known about the long-term impact, relative importance of dynamics–thermodynamics versus aerosol, and any difference by different types of aerosols.

Fast pH‐Driven Solubilization Method of Realgar (As4S4) to Reduce the Toxicity of Arsenic [As(III)] for Medicinal Purposes

Advanced Science, EarlyView.
Arsenic trioxide transformed acute promyelocytic leukemia therapy and shows promise against HIV. A new method to solubilize the mineral realgar produces different arsenic species depleting the main arsenic target, nuclear PML protein, and retaining effects on leukemic and HIV reservoir cells, while minimizing off‐target damage.

Tracking canopy gaps in mangroves remotely using deep learning

Remote Sensing in Ecology and Conservation, Volume 8, Issue 6, Page 890-903, December 2022., 2022
Canopy gaps greatly contribute to mangrove forest turnover and rejuvenation. While gap monitoring is usually performed by field and aerial surveys, we propose a novel method based on deep learning to achieve this automatically from very‐high‐resolution satellite imagery.
