Machine Learning for Local Detection of Separators in Three‐Dimensional Magnetic Fields

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 3, June 2026.
Abstract Magnetic reconnection is a major plasma phenomenon occurring in various key environments ranging from the Sun and near‐Earth space to astrophysical plasmas. While magnetic reconnection is relatively well‐understood under two‐dimensional (2D) settings, it remains challenging to characterize in three‐dimensional (3D) magnetic fields.

Nitric Oxide Radiative Relaxation Time: Damping Timescales of Lower Thermospheric Thermal Perturbations

Geophysical Research Letters, Volume 53, Issue 9, 16 May 2026.
Abstract Nitric oxide (NO) radiative cooling governs much of the energy budget in the Earth's lower thermosphere and damps out temperature perturbations. The radiative relaxation time (RRT), the timescale that defines how efficiently infrared radiation damps out the perturbations to the thermal structure to 1/e of the perturbation's initial value, is ...

Intersoftware variability in SPECT quality control: A technical note on analytical discrepancies and compliance decisions

Journal of Applied Clinical Medical Physics, Volume 27, Issue 5, May 2026.
Abstract Background Quality control (QC) is essential for ensuring the diagnostic reliability of Single‐Photon Emission Computed Tomography (SPECT) systems. However, the reliance on third‐party software for analyzing QC metrics introduces a potential source of variability that is not yet standardized.

Cuproptosis and Disulfidptosis Converge to Empower PD‐L1 Checkpoint Therapy via Cadict‐Induced PD‐L1 Translation

Advanced Science, Volume 13, Issue 25, 4 May 2026.
This study introduces Cadict, an EGFR‐targeted nanodrug that co‐delivers cuproptosis and disulfidptosis inducers to overcome immune resistance. Cadict synergistically enhances tumor cytotoxicity and sensitizes cancers to ICIs by upregulating PD‐L1 via an Eif5b‐dependent translation mechanism, fostering a potent antitumor immune response and ...

PAF Triggered Pyroptotic NETosis Aggravates Myocardial Ischemia/Reperfusion Injury

Advanced Science, Volume 13, Issue 25, 4 May 2026.
Platelet activating factor (PAF) secreted by cardiomyocytes during MI/R, drives NETs formation and subsequent NETosis. PAF/NETosis signaling activation is an initiative and causal factor in driving MI/R injury. This study identifies dapagliflozin as a potent NETosis inhibitor, and demonstrates that manipulating PAF‐NETosis signal by dapagliflozin or ...

Association and Comparative Analysis of Four Inflammatory Indices With 90‐Day Outcomes in Acute Ischemic Stroke Patients Treated With Intravenous Thrombolysis

Brain and Behavior, Volume 16, Issue 5, May 2026.
ABSTRACT Objective To investigate and compare the associations of the systemic immune‐inflammation index (SII), the systemic inflammation response index (SIRI), the platelet‐to‐lymphocyte ratio (PLR), and the neutrophil‐to‐lymphocyte ratio (NLR) with 90‐day functional outcomes in AIS patients treated with IV rt‐PA., with particular attention to their ...
