Predicting rainfall kinetic energy under forest canopies—A pilot study using ULS
Earth Surface Processes and Landforms, Volume 50, Issue 11, 15 September 2025.We applied the vegetation splash factor to predict the effect of vegetation on kinetic energy of rainfall and validated it with field data for the first time. Abstract Rainfall erosivity, expressed in kinetic energy, is determined by intensity, velocity and drop size distribution. In natural precipitation, these properties vary and can be substantially

Effect of Fluence Rate on Tumor Tissue Damage in IRDye700DX‐Based Photoimmunotherapy
Cancer Medicine, Volume 14, Issue 16, August 2025.The effects of the light dose and fluence rate of NIR‐PIT on its efficacy were analyzed. The obtained results showed that light dose influenced the level of cancer cell cytotoxicity in vitro and in vivo, while the fluence rate had no effect in vitro, but had a negative association with NIR‐PIT efficacy in vivo.

Advanced NanoBiomed Research, Volume 5, Issue 4, April 2025.Ultrasound transducers can be used to pattern microscale particles. Herein, it is shown that dynamic patterning, i.e., varying pattern location and direction using transmit beamforming, can be achieved using a (clinical)‐phased array transducer without the need for a reflector. Moreover, initial acoustic patterning results on living cells are presented,
