X-ray free-electron lasers can generate intense and coherent radiation at wavelengths
down to the sub-ångström region 1 , 2 , 3 , 4 – 5 , and have become indispensable tools for …

The methods of simultaneous extraction of polycyclic aromatic hydrocarbons (PAHs) and
organochlorine pesticides (OCPs) from soils using Soxhlet extraction, microwave-assisted …

Existing rotated object detectors are mostly inherited from the horizontal detection paradigm,
as the latter has evolved into a well-developed area. However, these detectors are difficult …

Rotation detection serves as a fundamental building block in many visual applications
involving aerial image, scene text, and face etc. Differing from the dominant regression-based …

Background: Primary liver cancer, around 90% are hepatocellular carcinoma in China, is
the fourth most common malignancy and the second leading cause of tumor-related death, …

Nanostructured Fe–N–C materials represent a new type of “platinum-like” non-noble-metal
catalyst for various electrochemical reactions and organic transformations. However, no …

Water electrolysis has been expected to assimilate the renewable yet intermediate energy‐derived
electricity for green H 2 production. However, current benchmark anodic catalysts of Ir…

Co–N–C catalysts are promising candidates for substituting platinum in electrocatalysis and
organic transformations. The heterogeneity of the Co species resulting from high-…

Boundary discontinuity and its inconsistency to the final detection metric have been the
bottleneck for rotating detection regression loss design. In this paper, we propose a novel …

As promising hydrogen energy carrier, formic acid (HCOOH) plays an indispensable role in
building a complete industry chain of a hydrogen economy. Currently, the biomass …
