Analysis of Secondary Particles as a Complement to Muon Scattering Measurements

Instruments, 2022
Cosmic ray tomography is an emerging imaging technique utilizing an ambient source of radiation. One common tomography method is based on the measurement of muons scattered by the examined objects, which allows the reconstruction and discrimination of ...

Integrating Automated Electrochemistry and High‐Throughput Characterization with Machine Learning to Explore Si─Ge─Sn Thin‐Film Lithium Battery Anodes

Advanced Energy Materials, Volume 15, Issue 11, March 18, 2025.
A closed‐loop, data‐driven approach facilitates the exploration of high‐performance Si─Ge─Sn alloys as promising fast‐charging battery anodes. Autonomous electrochemical experimentation using a scanning droplet cell is combined with real‐time optimization to efficiently navigate composition space.

Production of Secondary Cosmic Rays in Supernova Remnants [PDF]

Proceedings of The 34th International Cosmic Ray Conference — PoS(ICRC2015), 2016
We study production of secondary cosmic rays (CR) in supernova remnants (SNR). The model includes reacceleration of already existing in interstellar medium secondary CR particles as well as creation of secondary CRs in nuclear collisions of accelerated protons with gas nuclei and their subsequent acceleration by SNR shock.

The Bochum Survey of the Southern Galactic Disk: IV. Multi‐Band Photometry

Astronomische Nachrichten, EarlyView.
ABSTRACT The Southern Galactic Disk Survey (GDS) monitored a mosaic of 268 fields along a 6°‐wide stripe in the southern galactic disk from September 2010 to September 2019. These fields were observed between 21 and 407 times sim r′$$ {r}^{\prime } $$ultaneously in (8mag≲r′≲18mag$$ 8\kern0.6em \mathrm{mag}\lesssim {r}^{\prime}\lesssim 18\kern0.6em ...

Cosmic-Ray North–South Anisotropy: Rigidity Spectrum and Solar Cycle Variations Observed by Ground-based Muon Detectors

The Astrophysical Journal
The north–south (NS) anisotropy of galactic cosmic rays (GCRs) is dominated by a diamagnetic drift flow of GCRs in the interplanetary magnetic field (IMF), allowing us to derive key parameters of cosmic-ray propagation, such as the density gradient and ...

Mechanism study of an articular cartilage repair material and its forward‐looking test for space medicine

BMEMat, EarlyView.
The regeneration process following dLhCG engraftment progressed through four distinct and interconnected stages. dLhCG maintained its regenerative efficacy after 6 months of cosmic exposure, supporting its potential application in space medicine.

Fair Weather Neutron Bursts From Photonuclear Reactions by Extensive Air Shower Core Interactions in the Ground and Implications for Terrestrial Gamma‐ray Flash Signatures

Geophysical Research Letters, 2021
We report on anomalously long duration (2 ms) count rate bursts following the impact of cosmic ray showers near a 7.62 cm x⊘7.62 cm LaBr3 scintillation detector at the High Altitude Water Cherenkov array in Mexico, previously described by Stenkin et al. (

Compositional Stages in the Thermal Activation of Metal‐Organic Frameworks in Vacuo: In Situ Spectroscopy and Computation

Chemistry – A European Journal, EarlyView.
The ultrahigh surface area intrinsic to many metal‐organic frameworks (MOFs) may only be accessed after the removal of synthesis solvent from within the pores. This study elucidates the electronic and structural changes undergone through the guest removal process within a commonly used CUS MOF.

Production of Secondary Electrons by Cosmic Ray Particles [PDF]

Nature, 1938
SOME early measurements of Anderson and Nedder-meyer1 show that the number of single secondary electrons ejected by cosmic ray particles from a metal plate is in reasonable agreement with that to be expected from direct elastic collisions. In a series of photographs we have observed the traversal of a 2 cm.

Localizing value of ecstatic phenomenon in epilepsy surgery: A systematic review

Epileptic Disorders, EarlyView.
Abstract Objective A systematic review was conducted to synthesize current anatomo‐clinical correlations of ecstatic symptoms in focal epilepsy, aiming to provide evidence‐based guidance for interpreting this ictal semiology during presurgical evaluation.
