Radar Polarimetry in Glaciology: Theory, Measurement Techniques, and Scientific Applications for Investigating the Anisotropy of Ice Masses

open access: yesReviews of Geophysics, Volume 63, Issue 4, December 2025.
Abstract Dielectric anisotropy in ice alters the propagation of polarized radio waves, so polarimetric radar sounding can be used to survey anisotropic properties of ice masses. Ice anisotropy is either intrinsic, associated with ice‐crystal orientation fabric (COF), or extrinsic, associated with material heterogeneity, such as bubbles, fractures, and ...

FeCu/MWCNT Nanocomposite with a Broad Microwave Absorption Band and Highly Reduced Radar Cross Section and Farfield

open access: yesAdvanced Electronic Materials, Volume 11, Issue 15, September 18, 2025.
FeCu bimetallic nanoparticles were synthesized using coprecipitation method. FeCu bimetallic nanoparticles decorated onto the MWCNT's sidewall with different weight ratios to produce novel FeCu/MWCNT nanocomposites. The results showed that a thin nanocomposite exhibited a broad absorption band with coverage of entire frequency bands.

Solar neutrinos and neutrino mixing

open access: yesPhysics Letters B, 1976
Abstract The recent suggestion that mixing of many neutrino types accounts for the solar neutrino puzzle is discussed. We find that in general the suppression due to mixing of k species is by less than a factor k.

Monitoring Fracture Hydromechanical Evolution in the Lab and Field Using Unsupervised Metric Learning

open access: yesJournal of Geophysical Research: Machine Learning and Computation, Volume 2, Issue 3, September 2025.
Abstract Fractures evolve in time through thermal‐hydraulic‐mechanical‐chemical (THMC) processes that alter their long‐range hydraulic transport properties and modify subsurface behavior and activities. The location of subsurface fractures makes it necessary to use remote sensing techniques such as passive or active seismic monitoring for fracture ...

CP-conserving SO(3) parameterization of the neutrino mixing matrix

open access: yesPhysics Letters B
The pattern of neutrino mixing, usually parameterized by the Pontecorvo-Maki-Nakagawa- Sakata UPMNS matrix, still remains a striking puzzle in particle physics. UPMNS is one of six possible products of multiplying three Euler matrices.

Mixing of active and sterile neutrinos [PDF]

open access: yesJournal of High Energy Physics, 2011
We investigate mixing of neutrinos in the $ν$MSM (neutrino Minimal Standard Model), which is the MSM extended by three right-handed neutrinos. Especially, we study elements of the mixing matrix $Θ_{αI}$ between three left-handed neutrinos $ν_α$ ($α= e,μ,τ$) and two sterile neutrinos $N_I$ ($I=2,3$) which are responsible to the seesaw mechanism ...

Invisible Labor and the “Ghost Particle”: Underground Physics at the Kolar Gold Fields**

open access: yesBerichte zur Wissenschaftsgeschichte, Volume 48, Issue 1-2, Page 163-179, August 2025.
Abstract When cosmic rays—high‐energy particles from outer space—encounter the Earth's atmosphere, they produce particles called neutrinos. To detect them, physicists go underground inside deep mines where the overlying rock can filter out the cosmic‐ray background radiation.
