CT angiography (CTA) of the aortoiliofemoral (AIF) arteries in the abdomen, pelvis, and lower extremities has become an invaluable tool in assessment of patients with peripheral arterial disease (PAD) and lower extremity trauma. AIF CTA provides rapid and comprehensive assessment of arterial inflow and outflow, guiding management of patients with chronic claudication and those with more acute manifestations, including atherothrombotic occlusion, embolic disease, or thrombosis of prior interventions such as bypass graft or stent placement. Careful attention to technique is critical in performing diagnostic AIF CTA, as pitfalls related to imaging too early or too late relative to the arrival of contrast material in the legs can lead to misdiagnosis or diagnostic uncertainty.

Natural language processing (NLP) has undergone extensive transformation since its infancy from rule-based systems to the sophisticated architectures of today's machine learning models. Initially, NLP relied on hard-coded grammar rules and dictionaries, which were labor-intensive and lacked flexibility. With the introduction of statistical NLP in the late 20th century, machines began learning language patterns from large datasets, improving fluency and scalability.

Earthquake Early Warning (EEW) systems can provide seconds to tens of seconds of advanced notice before the arrival of destructive seismic waves. Their effectiveness, however, depends on how quickly and accurately each system forecasts ground motion using real-time data. This study compares the performance of two distinct EEW algorithms (PLUM (Kodera et al.

Artery of Percheron (AOP) infarction is a rare form of ischemic stroke resulting from the occlusion of a single arterial trunk that supplies both sides of the paramedian thalamus and the midbrain. Its occlusion can lead to bilateral and symmetrical infarctions of the paramedian thalami, and occasionally, the midbrain. Due to its atypical presentation, this condition is often diagnosed late.

Priority effects-the phenomenon where early-arriving species influence the establishment, growth, and reproduction of later-arriving species during community assembly-play a critical role in determining the invasion success of exotic species. However, how priority effects are influenced by nitrogen (N) availability remains understudied. The invasive species has rapidly expanded its range in China over the past few years.
