Revealing the relationship between 2‐D and 3‐D chondrule size–frequency distribution in a meteorite
Abstract Chondrule size–frequency distributions provide important information to understand the origin of chondrules. Size–frequency distributions are often obtained as apparent 2‐D size–frequency distributions in thin sections, as determining a 3‐D size–frequency distribution is notoriously difficult.

Abstract Troilite is a common phase in iron meteorites, but there are limited data available for the partitioning behavior of elements between troilite and solid metal. In this study, we present the results of experiments with coexisting Fe‐Ni solid metal, an S‐rich metallic liquid, and troilite, conducted at 800–925°C in evacuated silica tubes at 1 ...

Multi‐isotope (N, O, Ti, and Cr) study of C1 and CM‐like clasts—Probing unsampled C1 material
Abstract A multi‐element isotope (N, O, Ti, and Cr) study was conducted on C1 and CM‐like clasts hosted in achondrites and chondrite breccias to understand the genesis of these chondritic clasts. The mineralogy, O, and N isotopes confirm that CM‐like clasts in howardites and polymict eucrites closely resemble CM chondrite‐like material.

Abstract Combining electron backscatter diffraction (EBSD) with X‐ray computed tomography (XCT) offers a comprehensive approach to investigate shock deformation and rock texture in meteorites, yet such integration remains uncommon. In this study, we demonstrate the synergistic potential of XCT and EBSD in revealing deformation metrics, thereby ...

Volume measurement of microparticles using SEM photogrammetry and 3‐D reconstruction
Abstract In this paper, we introduce a method for volume measurement of microparticles that includes scanning electron microscope photogrammetry with 3‐D model construction. Our results show that our method limits the volume uncertainty to ±10%, which is a significant improvement compared to previous methods (which likely overestimated volume by 100 ...

Abstract The “integration paradox” posits that seemingly well‐established immigrants and their descendants tend to report more discrimination compared to their more marginalized peers. This study investigates one potential mechanism for this paradox, namely, the increasing awareness of their group's enduring ethno‐racial minority status.

Novel treatment of infectious keratitis in canine corneas using ultraviolet C (UV‐C) light
Abstract Objective To investigate the therapeutic effect of 275 nm wavelength ultraviolet C (UV‐C) light for treatment of bacterial keratitis in canine corneas using an affordable, broadly available modified handheld device. Methods UV‐C therapy (UVCT) was evaluated in two experiments: in vitro using triplicates of three bacterial genera ...

Ultraviolet C (UV‐C) Light Therapy for Equine Ulcerative Keratomycosis—An In Vitro Study
ABSTRACT Objectives To assess if an affordable, commercially available 275 nm ultraviolet C (UV‐C) device can inhibit fungal pathogens associated with equine keratomycosis and to establish the optimal exposure time/dose required in vitro. Methods Fungal inhibition zone surface areas of isolates from two fungal genera (Aspergillus and Fusarium spp ...

A comparison of Hochschild homology in algebraic and smooth settings
Abstract Consider a complex affine variety V∼$\tilde{V}$ and a real analytic Zariski‐dense submanifold V$V$ of V∼$\tilde{V}$. We compare modules over the ring O(V∼)$\mathcal {O} (\tilde{V})$ of regular functions on V∼$\tilde{V}$ with modules over the ring C∞(V)$C^\infty (V)$ of smooth complex valued functions on V$V$.
