Membranous dysmenorrhea and decidual casts: A scoping review
International Journal of Gynecology &Obstetrics, EarlyView.Abstract Background Membranous dysmenorrhea, characterized by the expulsion of intact endometrial tissue rather than gradual dissolution during menstruation, occasionally presents as a decidual cast—a complete triangular mold of the uterine cavity. This poorly understood condition is likely underdiagnosed.

Witt group of Hermitian forms over a noncommutativediscrete valuation ring [PDF]
International Journal of Mathematics and Mathematical Sciences, 2005 We investigate Hermitian forms on finitely generated torsion modules over a noncommutative discrete valuation ring. We also give some results for lattices, which still are satisfied even if the base ring is not commutative. Moreover, for a noncommutative discrete-valued division algebraD with valuation ring R and residual division algebra , we prove ...

JCPP Advances, EarlyView.Our umbrella synthesis found strong, often equivalent, associations between child maltreatment and all examined mental health difficulties. Different types of maltreatment appear to have comparably negative effects on mental health. If replicated, these findings may cause us to reconsider conventional wisdom that suggests some forms of CM are less ...

Ideal class groups of Witt rings
Journal of Algebra, 1989 Let F denote a formally real field and \(R=WF\) the Witt ring of classes of nondegenerate quadratic forms over F. As usual, IF denotes the ideal of even dimensional classes in R and \(X_ F\) the space of orders of F. The author continues his study of the ring properties of R, begun in [J. Algebra 96, 368-385 (1985; Zbl 0574.10028)].

Naval Research Logistics (NRL), EarlyView.ABSTRACT This paper addresses two‐dimensional orthogonal packing within a confined space, integrating bin packing principles with facility layout concepts to address scenarios in which items must not only fit but also be arranged according to spatial priorities.

People and Nature, EarlyView.Abstract Millions of hectares of rangelands have been subject to degeneration through overgrazing, agricultural expansion, urbanisation and afforestation. Countering this, regeneration is a natural process whereby rangeland ecosystems revive themselves.

Thunderbird International Business Review, EarlyView.ABSTRACT Focusing on the Belt and Road Initiative (BRI), this study investigates how national security drives the coevolution of China's political risk management support for multinationals and competing countries' reactions. A competing country is a nation‐state that is neither the home nor host country of a multinational but perceives the ...

The Burnside ring of profinite groups and the Witt vector construction
Advances in Mathematics, 1988 Let G be an arbitrary profinite group. The authors construct a functor \(W_ G\) from the category of commutative rings to itself such that \(W_ G({\mathbb{Z}})\simeq {\hat \Omega}(G)\), where \({\hat \Omega}\)(G) is the completed Burnside ring. If \(G=\hat C\) (resp. \(\hat C_ p)\) the profinite (resp.

Determinants of case outcomes in Rwanda's postgenocide gacaca courts
Criminology, EarlyView.Abstract Transitional justice trials have become a central mechanism for addressing mass violence and human rights violations, yet little is known about the determinants of case outcomes within these courts—particularly in domestic contexts. This study examines Rwanda's gacaca courts, a localized transitional justice system that tried people suspected ...

Witt Groups of the Punctured Spectrum of a 3-Dimensional Regular Local Ring and a Purity Theorem [PDF]
Journal of the London Mathematical Society, 1999 Let \(A\) denote a regular local ring, in which \(2\) is invertible, and let \(K\) denote the quotient field. The authors prove part of the Gersten conjecture, if \(A\) is \(3\)-dimensional, namely that the second residue homomorphisms at prime ideals of height \(1\) induce an exact sequence of Witt groups of quadratic forms \[ 0 \rightarrow W(A ...
