Enhanced heat transfer and fluid motion in 3D nanofluid with anisotropic slip and magnetic field

open access: yesOpen Physics
A mathematical model is envisaged that discusses the motion of 3D nanofluids (NFs) with anisotropic slip influence magnetic field past a stretching sheet.

Bow Shock Current Closure Through the Magnetosheath for Non‐Zero IMF By—Results From Hybrid Simulations

open access: yesJournal of Geophysical Research: Space Physics, Volume 131, Issue 8, August 2026.
Abstract The bow shock current (BSC) flows on the bow shock due to the compression of the interplanetary magnetic field (IMF) across the shock. Although previous studies have shown that the BSC can connect to magnetospheric current systems via the magnetosheath, it is still not known how this happens.

Excitation of Large Amplitude Compressional ULF Waves in the Magnetosphere by Solar Wind Pressure Spikes and IMF Southward Turning

open access: yesJournal of Geophysical Research: Space Physics, Volume 131, Issue 8, August 2026.
Abstract We present a case study of large amplitude, compressional Pc5 waves observed by GOES 13 and 15 at geosynchronous orbit near noon. These waves were excited near the arrival time of two consecutive solar wind dynamic pressure spikes at the magnetopause, the second of which was associated with a large and rapid southward turning of the ...

Alfvénic Poynting Flux Characterized by a Substorm‐SMC Cycle and Ionospheric Influence

open access: yesSpace Weather, Volume 24, Issue 8, August 2026.
Abstract Geomagnetic substorms are fundamental processes of explosive geospace energy release within the Earth's magnetotail, which are usually divided into three phases: the growth phase, the expansion phase, and the recovery phase. Large‐scale electromagnetic energy transport during a geomagnetic substorm is in the form of Alfvén waves, transmitting ...

Patient‐reported outcomes, postoperative pain and pain relief after day‐case surgery (POPPY): short‐term peri‐operative analgesic use

open access: yesAnaesthesia, Volume 81, Issue 8, Page 1057-1067, August 2026.
Summary Introduction An increasing proportion of complex surgical procedures are being performed in the UK as day‐cases, with variable and limited follow up. Discharge prescriptions must provide adequate analgesia, while considering the safety of the patient and public, following best practice guidance and good opioid stewardship.

Local Evolution of a Prenoon Drainage Plume

open access: yesGeophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract Plasmaspheric drainage plumes are typically observed in the postnoon sector during geomagnetic storms, but their local evolution in the prenoon sector remains poorly understood. Here, we report in situ observations from the Van Allen Probe, revealing multiple localized enhancements in cold electron density near apogee in the prenoon sector ...

Martian Magnetotail Neutral Sheet Asymmetry Driven by Heavy Planetary Pickup Ions

open access: yesGeophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract In the induced magnetotail of Mars, the neutral sheet is an important channel for atmospheric ion escape, yet the role of heavy planetary pickup ions in shaping its geometry has been unclear. Using three‐dimensional hybrid simulations, we demonstrate that these ions induce a global neutral sheet asymmetry via mass loading.

MHD Gleichgewicht und MHD-Stabilität in Rennbahngeometrie

open access: yes, 1976
The transverse field of a racetrack Tokamak in equilibrium is calculated for surface currents and Zarge aspect ratio via the law of Biot-Savart, and its structure is discussed. The discontinuities of the curvature lead to jumps in the vertical component and to the appearance of a horizontal component.

Unraveling the Fine‐Scale Tapestry of Solar Wind at 1AU

open access: yesGeophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract Solar wind is a complex network of distinct magnetic flux tubes, each contained and separated by a current sheet. In this study, more than 50,000 current sheets in the solar wind are identified and characterized for the first time, using multi‐point Cluster observations during solar minimum and maximum intervals.
