Visible to Mid‐Infrared Optical Constants of Orthopyroxenes
Earth and Space Science, Volume 9, Issue 4, April 2022., 2022 Abstract Radiative transfer models of remotely acquired infrared spectra result in quantitative identification of minerals on planetary surfaces. Optical constants, or the real (n) and imaginary (k) indices of refraction are necessary inputs in such models.

Animal models of pulmonary hypertension: Getting to the heart of the problem
British Journal of Pharmacology, Volume 179, Issue 5, Page 811-837, March 2022., 2022 Despite recent therapeutic advances, pulmonary hypertension (PH) remains a fatal disease due to the development of right ventricular (RV) failure. At present, no treatments targeted at the right ventricle are available, and RV function is not widely considered in the preclinical assessment of new therapeutics.

Unmixing Mineral Abundance and Mg# With Radiative Transfer Theory: Modeling and Applications
Journal of Geophysical Research: Planets, Volume 126, Issue 2, February 2021., 2021 Abstract Mineral abundance and Mg# (100× molar Mg/(Mg + Fe)) are significant in understanding the crustal composition and thermal history of the Moon. In this study, we derive a new set of optical constants for olivine, orthopyroxene, and clinopyroxene using radiative transfer equations that include soil porosity and the opposition effect. Based on the

Communications of the Byurakan Astrophysical Observatory, 2023 A new approach to solving of the Ambartsumian’s functional equation is presented. Its application is illustrated on the two classical cases: a) in the case of a plane-parallel semi-infinite medium with monochromatic anisotropic scattering and b) the simple one-dimensional problem of diffuse reflection of radiation from the scattering-absorbing semi ...

A Method of Finding Source Function for Inverse Diffusion Problem with Time‐Fractional Derivative
Advances in Mathematical Physics, Volume 2016, Issue 1, 2016., 2016 The Homotopy Perturbation Method is developed to find a source function for inverse diffusion problem with time‐fractional derivative. The inverse problem is with variable coefficients and initial and boundary conditions. The analytical solutions to the inverse problems are obtained in the form of a finite convergent power series with easily obtainable

Modified Theories of Gravitation behind the Spacetime Deformation
Physics Research International, Volume 2015, Issue 1, 2015., 2015 In the framework of proposed theory of spacetime deformation/distortion, we have a way to deform the spacetime through a nontrivial choice of the distortion‐complex, displaying different connections, which may reveal different post‐Riemannian spacetime structures as corollary. We extend this theory to address, in particular, the gauge model of the most

Growth of Accreting Supermassive Black Hole Seeds and Neutrino Radiation
Journal of Astrophysics, Volume 2015, Issue 1, 2015., 2015 In the framework of microscopic theory of black hole (MTBH), which explores the most important processes of rearrangement of vacuum state and spontaneous breaking of gravitation gauge symmetry at huge energies, we have undertaken a large series of numerical simulations with the goal to trace an evolution of the mass assembly history of 377 plausible ...

A Brief Observational History of the Black‐Hole Spacetimes
Advances in Mathematical Physics, Volume 2015, Issue 1, 2015., 2015 In this year (2015), black holes (BHs) celebrate their 100th birthday, if their birth is taken to be triggered by a handwritten letter from Martin Schwarzschild to Albert Einstein, in connection with his newly found spherically symmetric vacuum solution.

Screening and identification of small molecule inhibitors of ErbB2‐induced invasion
Molecular Oncology, Volume 8, Issue 8, Page 1703-1718, December 2014., 2014 ERBB2 amplification and overexpression are strongly associated with invasive cancer with high recurrence and poor prognosis. Enhanced ErbB2 signaling induces cysteine cathepsin B and L expression leading to their higher proteolytic activity (zFRase activity), which is crucial for the invasion of ErbB2‐positive breast cancer cells in vitro.

The Influence of Space Weathering on the Far‐Ultraviolet Reflectance of Apollo‐Era Soils
Journal of Geophysical Research: Planets, Volume 130, Issue 12, December 2025.Abstract Building on our previous studies of the far‐ultraviolet (FUV) reflectance of Apollo soil 10084 and lunar soil simulants JSC‐1A and LMS‐1 (Gimar et al., 2022, https://doi.org/10.1029/2022je007508; Raut et al., 2018, https://doi.org/10.1029/2018je005567), we present new FUV results for Apollo soils 68501 and 71061. Heavily weathered soils (68501,
