Abstract Nowcasting of convective storms is urgently needed yet rather challenging. Current nowcasting methods are mostly based on radar echo extrapolation, which suffer from the insufficiency input information and ineffectiveness model architecture. A novel deep‐learning (DL) model, FURENet, designed for extracting multiple variables to make predictions. Polarimetric variables, K DP Z DR , provide extra microphysics dynamic structure storms, fed into improve nowcasting. Two representative...
Abstract The layer‐by‐layer (LbL) solution‐processed organic solar cells (OSCs) are conductive to achieve vertical phase separation, tunable donor–acceptor (D/A) interfaces, and favorable charge‐transport pathways. In this work, a wide‐bandgap component poly(9‐vinylcarbazole) (PVK) is added the upper electron acceptor layer improve performance of LbL‐processed OSCs. Results show that PVK can adjust film morphology, dope acceptor, increase concentration, charge transport. Such n‐type doping...
Abstract Y‐series nonfullerene acceptors (NFAs) usually bear halogenated end groups to achieve narrow bandgaps and tunable molecules crystallinity; however, it results in small open‐circuit voltage ( V oc ) of 0.8–0.9 V. Here, three NFAs BTP‐eC9‐G51, BTP‐eC9‐G52, BTP‐eC9‐G53 are synthesized by introducing both an electron‐withdrawing fluoro group electron‐donating alkoxy commonly used 2‐(3‐oxo‐2,3‐dihydroinden1‐ylidene)‐malononitrile (IC) terminal groups. These compounds demonstrate a high...
Abstract This study is the first attempt to investigate characteristics of drop size distribution (DSD) and shape relation (DSR) seven typhoons after making landfall in China. Four were sampled by a C‐band polarimetric radar (CPOL) two‐dimensional video disdrometer (2DVD) Jiangsu Province (East China) while three two 2DVDs Guangdong (south China). Although DSD DSR are different individual typhoons, computed parameters these groups possess similar characteristics. The more spherical,...

Abstract Using observations from the dual‐frequency precipitation radar (DPR) onboard Global Precipitation Measurement mission (GPM) satellite, this study analyzes microphysical structures and processes of tropical cyclone (TC) over western North Pacific in terms different efficiency indices (PEIs). The statistical results show that mean mass‐weighted diameter raindrops ( D m ) at 2 km is 1.67 mm (1.37 mm) for convective (stratiform) precipitating clouds. Precipitating clouds with high PEI...
The performance of current Scene Graph Generation models is severely hampered by some hard-to-distinguish predicates, e.g., "woman-on/standing on/walking on-beach" or "woman-near/looking at/in front of-child". While general SGG are prone to predict head predicates and existing re-balancing strategies prefer tail categories, none them can appropriately handle these predicates. To tackle this issue, inspired fine-grained image classification, which focuses on differentiating among object...
Compared to query-based black-box attacks, transferbased attacks do not require any information of the attacked models, which ensures their secrecy. However, most existing transfer-based approaches rely on ensembling multiple models boost attack transferability, is time- and resource-intensive, mention difficulty obtaining diverse same task. To address this limitation, in work, we focus single-model object detection, utilizing only one model achieve a high-transferability adversarial...
Abstract This study analyzes the microphysics of convective cells in an outer rainband Typhoon Nida (2016) using data collected by a newly upgraded operational polarimetric radar China. The life cycle these is divided into three stages: developing, mature, and decaying according to intensity corresponding updraft. Composite analysis shows that deep columns ZDR KDP collocate well with enhanced updraft as develop their mature stage. A layered microphysical structure observed ice region riming...
