Researchers have explored various methods to fully exploit the all-weather characteristics of Synthetic aperture radar (SAR) images achieve high-precision, real-time, computationally efficient, and easily deployable ship target detection models. These include Constant False Alarm Rate (CFAR) algorithms deep learning approaches such as RCNN, YOLO, SSD, among others. While these outperform traditional in SAR detection, challenges still exist handling arbitrary distributions small features...
We present a kinetic Monte Carlo method for simulating chemical transformations specified by reaction rules, which can be viewed as generators of reactions, or equivalently, definitions classes. A rule identifies the molecular components involved in transformation, how these change, conditions that affect whether transformation occurs, and rate law. The computational cost method, unlike conventional simulation approaches, is independent number possible need not advance explicitly generated...

It achieves directly‐driven electroluminescence phenomenon in real‐time by triboelectrification works completely...
Hainan tropical rainforest is the largest contiguous in China, but it has experienced increasing disturbances from anthropogenic activities recent decades due to economic and social development. However, current status of wildlife habitats within remains insufficiently studied, lacking systematic scientific assessments necessary guide effective biodiversity conservation strategies. This study focuses on Jianfengling area rainforest, using infrared camera monitoring data habitat environmental...
The issue of cadmium (Cd) contamination in agricultural soils has garnered significant attention due to its implications for food safety and environmental health. However, research on spatial temporal distribution tropical zones with high intensity cropping remains limited.

By synthesizing 165 records from 4110 sampling sites, the...
Deducing plausible reaction schemes from single-channel current traces is time-consuming and difficult. The goal to find the simplest scheme that fits data, but there are many ways connect even a small number of states (>2 million with four open closed states). Many make identical predictions. An exhaustive search over model space does not address equivalent will result. We have found canonical form can express all for binary channels. This has minimal rate constants any rank (number...
Due to advances in satellite and sensor technology, the number size of Remote Sensing (RS) images continue grow at a rapid pace.
