Open Magnetic Field Lines Partition Auroral Oval Segments Into Transpolar Arcs
Abstract Transpolar arcs (TPAs) are auroral structures spanning the polar cap. One type appears in conjugate hemispheres and is thought to be located on closed field lines, but how closed flux enters the open polar cap remains debated. We address this using observation and simulation of conjugate TPAs after an interplanetary magnetic field (IMF) By ...

Global Occurrence of Solitary Waves in the Martian Magnetosphere
Abstract This letter presents a global occurrence of bipolar solitary waves (SWs) in the Martian magnetosphere. We utilized medium‐frequency electric field measurements from October 2014 to December 2023 from the Mars Atmosphere and Volatile EvolutioN (MAVEN) spacecraft.

Abstract Geomagnetic disturbances in polar regions can be decomposed into two main patterns: the Disturbance Polar (DP) 1 and 2. How their relative contribution reshapes global current system remains unclear. In this study, we classified substorms from 2010 to 2022 into weak and strong DP‐2 events based on the ratio of the eastward to westward auroral ...

Health Care Utilization in Adults With Congenital Heart Disease: Population‐Based Findings
ABSTRACT Background Population‐based data on healthcare utilization in adults with congenital heart disease (CHD) are limited. We examined utilization patterns in a multi‐site, population‐based U.S. cohort of adults with CHD. Methods This retrospective cohort linked health and administrative records from five regions (Colorado, North Carolina, Utah ...

To identify promising locations where Largetooth Sawfish, Pristis pristis, may persist, a novel species‐specific Droplet Digital PCR (ddPCR) assay was designed capable of detecting a single copy of DNA, with in silico and in vitro validation experiments indicating functionality across the species' historical range.

Abstract Strong Thermal Emission Velocity Enhancement (STEVE) is a nightsky optical phenomenon of great research interest in recent years. STEVE is recognized to be co‐located with a latitudinally narrow channel of fast westward ion drifts, also known as “subauroral ion drifts” (SAID).

Abstract The afternoon detached auroral arc is an important phenomenon in the subauroral region, reflecting coupling processes between the Earth's magnetosphere and ionosphere. Previous studies have not identified fine‐scale structures in such arcs, leaving the dynamics underlying their formation poorly understood.

Abstract A local vortex‐structured aurora and a large‐scale transpolar arc (TPA) were contemporaneously observed by the Polar ultraviolet imager (UVI) during the late recovery phase of a substorm, and the interplanetary magnetic field (IMF) BY and BZ were negative and negative‐to‐positive. The TPA grew along the dawnside auroral oval from the nightside
