Ultra‐Low‐L Sub‐MeV Electron Microbursts During the May 2024 Super Storm

open access: yesGeophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract During the May 2024 super storm, we identified sub‐second microburst‐type relativistic electron precipitation events at McIlwain's L∼2 $L\sim 2$ in low‐Earth orbit using the Gamma‐ray Burst Monitor (CGBM) onboard the CALorimetric Electron Telescope on the International Space Station.

Terrestrial Gamma‐Ray Flash Following Intense Negative Return Stroke Observed With BIMAP‐3D

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 13, 16 July 2026.
Abstract We report ground‐based observations of a terrestrial gamma‐ray flash (TGF) associated with a strong negative cloud‐to‐ground lightning strike (‐CG) which occurred near Los Alamos National Laboratory (LANL) in New Mexico, USA. Gamma photons were detected by the Terrestrial High‐energy Observations of Radiation (THOR) instrument, developed at ...

Synthesis of Arylsilanes by Catalytic Silylation of C(sp2)─X Bonds: A Review From the Silicon Perspective

open access: yesAsian Journal of Organic Chemistry, Volume 15, Issue 7, July 2026.
This review surveys the synthesis of arylsilanes by catalytic silylation of C(sp2)−X bonds from an original silicon perspective. By categorizing methodologies based on the philicity of the silylating reagents, moving from abundant electrophilic silicon sources to more specialized nucleophilic ones, it highlights the structural diversity of silyl groups

A Twisted Tale: Ileocolic Intussusception in an Adult: A Case Report

open access: yesClinical Case Reports, Volume 14, Issue 7, July 2026.
Excised specimen of adult intussusception. ABSTRACT Adult intussusception is a rare but serious surgical emergency with various underlying aetiologies. A high index of clinical suspicion and early diagnosis can help guide its management. The following case report describes the presentation, diagnosis, and management of an adult ileocolic ...

Nonsurgical Correction of Brodie Bite in Mixed Dentition Using Quad‐Helix Expansion: A Case Report

open access: yesClinical Case Reports, Volume 14, Issue 7, July 2026.
ABSTRACT This case report presents a nonsurgical correction of a dentoalveolar Brodie bite in a mixed dentition patient using a quad‐helix appliance. Mandibular expansion resolved the transverse discrepancy within 3 months, improving occlusion, and eliminating a habitual mandibular shift that had contributed to facial asymmetry.

Simultaneous multi-piston measurement method in segmented telescopes

open access: yesOptics Express, 2017
We propose a method to simultaneously detect the multi-piston between segments. The relation between the piston of any two segments and amplitude of the modulation transfer function (MTF) sidelobes (MTFnph) is derived. The piston can be retrieved by this relation after measuring the MTFnph. This method's capture range is the operating light's coherence

Airway Involvement in Conradi–Hünermann–Happle Syndrome: A Novel Clinical Manifestation

open access: yesThe Laryngoscope, Volume 136, Issue 7, Page 3240-3245, July 2026.
We report the first documented case of airway involvement in Conradi–Hünermann–Happle syndrome (CDPX2), an X‐linked dominant form of chondrodysplasia punctata caused by pathogenic variants in EBP. A 2‐month‐old female with genetically confirmed CDPX2 developed severe subglottic stenosis and persistent respiratory distress requiring CPAP; cross ...

Quantum limits of parameter estimation in long-baseline imaging

open access: yesPhysical Review Research
Telescope systems with distributed apertures are a well-established approach for boosting resolution in astronomical imaging. However, theoretical limits on quantitative imaging precision, and the fundamentally best possible mode-sorting, beam-combining,

Supervised classification of solar features using prior information

open access: yesJournal of Space Weather and Space Climate, 2015
Context: The Sun as seen by Extreme Ultraviolet (EUV) telescopes exhibits a variety of large-scale structures. Of particular interest for space-weather applications is the extraction of active regions (AR) and coronal holes (CH).

Material Property Sensitivity of Light Curve Attitude Estimation for the Lunar Trailblazer

open access: yesEarth and Space Science, Volume 13, Issue 7, July 2026.
Abstract The Lunar Trailblazer (LTB) spacecraft launched on 27 February 2025, toward a planned low‐lunar orbit. Eleven hours into its mission, contact with Trailblazer was lost, and recovery efforts began. Estimating the orientation and angular velocity state of Trailblazer was central for recovery to determine whether and when the vehicle could be ...
