Framework for X‐ray mirror surface shape fitting

Journal of Synchrotron Radiation, EarlyView.
The closed‐form expressions for elliptic cylinders, hyperbolic cylinders, ellipsoids, hyperboloids, and diaboloids used for X‐ray mirror surface shapes are summarized. Additionally, a four‐layer framework to fit the measured surface shape data in slope or height for convenient X‐ray mirror surface characterization is proposed.For accurate ...

Exploring oxide quasicrystals in internal space

Acta Crystallographica Section A, EarlyView.
The internal space expansion with variable system size is investigated for three different oxide quasicrystal systems. Patches of 7800, 4800 and 3600 vertices are examined in Ba–Ti–O/Pt(111), Eu–Ti–O/Pd(111) and Sr–Ti–O/Pd(111), respectively. This internal space inspection provides unique structural information for quasicrystalline systems, which goes ...

Existence and multiplicity of solutions to superlinear periodic parabolic problems

Electronic Journal of Differential Equations, 2018
Let $\Omega\subset\mathbb{R}^{N}$ be a smooth bounded domain and let a,b,c be three (possibly discontinuous and unbounded) T-periodic functions with $c\geq0$.

War and Peace: Ogawa Takemitsu's Theological Engagement with State and Religion

Journal of Religious History, EarlyView.
The Manchurian Incident of 1931 marked a pivotal moment in the rise of Japanese fascism. During the period from this incident until the Pacific War's defeat, dissent from the state's control was not tolerated, leading to coercive measures in religious communities. The Christian community, rather than devising theological reasoning to resist the state's

Was Einhard a widower?

Gender &History, EarlyView.
Abstract The ‘widow’ is a gendered, socially contingent category. Women who experienced spousal bereavement in the early middle ages faced various socio‐economic and legal ramifications; the ‘widow’ was further a rhetorical figure with a defined emotional register. The widower is, by contrast, an anachronistic category.

Storage games

The RAND Journal of Economics, EarlyView.
ABSTRACT We study a long‐horizon, oligopolistic market with random shocks to demand that can be arbitraged by two storage operators with finite capacity. This problem applies to any storable commodity—that is, most commodities. Because the arbitrage spread is so sensitive to market power, storage operators face strong incentives to restrain quantities ...
