Optimal mud pressure design using nonlinear failure criteria for wellbores in shaley sedimentary reservoir

open access: yesDeep Underground Science and Engineering, Volume 5, Issue 1, Page 144-159, March 2026.
The present study uses the Modified Mohr‐Coulomb true‐triaxial failure criterion (MMC_TT), which predicts the strength of rock better than the MGC criterion in laboratory true‐triaxial tests to overcome the limitations. Moreover, based on the data from previously published five vertical wells in the Krishna‐Godavari basin (K‐G basin), an empirical ...

Rational points in a family of conics over F2(t)$\mathbb {F}_2(t)$

open access: yesMathematische Nachrichten, Volume 299, Issue 3, Page 496-513, March 2026.
Abstract Serre famously showed that almost all plane conics over Q$\mathbb {Q}$ have no rational point. We investigate versions of this over global function fields, focusing on a specific family of conics over F2(t)$\mathbb {F}_2(t)$ which illustrates new behavior.

The integer cohomology of toric Weyl arrangements [PDF]

open access: yes
A toric arrangement is a finite set of hypersurfaces in a complex torus, every hypersurface being the kernel of a character. In the present paper we prove that if T(W) is the toric arrangement defined by the cocharacters lattice of a Weyl group W, then ...

Churchill and Germany: A ‘Special’ Relationship

open access: yesHistory, Volume 111, Issue 395, Page 237-254, March 2026.
Abstract No other country defined the trajectory of Churchill's political career more than Germany, a country of which he had little direct knowledge but which he either sought to emulate, accommodate or oppose throughout his time in politics. This article traces Churchill's relationship with Germany from his entry into politics at the beginning of the

Voronoi tilings, toric arrangements and degenerations of line bundles I

open access: yes, 2020
We describe limits of line bundles on nodal curves in terms of toric arrangements associated to Voronoi tilings of Euclidean spaces. These tilings encode information on the relationship between the possibly infinitely many limits, and ultimately give rise to a new definition of limit linear series.

The homotopy type of toric arrangements [PDF]

open access: yes
A toric arrangement is a finite set of hypersurfaces in a complex torus, every hypersurface being the kernel of a character. In the present paper we build a CW-complex S homotopy equivalent to the arrangement complement ℜ x, with a combinatorial ...

The McKinleys of Punch: Politics and the Press in Melbourne, 1870s to 1920s

open access: yesAustralian Journal of Politics &History, Volume 72, Issue 1, Page 35-68, March 2026.
This article re‐examines the Melbourne Punch (1855–1925; known simply as Punch from 1900) as a political weapon in the cut‐and‐thrust of Victorian, local, and national politics, in the hands of its longest‐serving, but least‐known proprietor, Alexander McKinley (1848–1927).

Vanishing results for the cohomology of complex toric hyperplane complements [PDF]

open access: yes
Suppose R is the complement of an essential arrangement of toric hyperlanes in the complex torus and ? = ?1(R). We show that H*(R;A) vanishes except in the top degree n when A is one of the following systems of local coefficients: (a) a system of ...

Decolonial limits to Henri Lefebvre's spatial revolution

open access: yesTransactions of the Institute of British Geographers, Volume 51, Issue 1, March 2026.
Short Abstract This commentary appreciates Hamish Kallin's (2024) account of the prospects for reconciliation of anarchist and Marxist approaches via engaging Henri Lefebvre's work, but signals equivocation about Lefebvre triggered by his depictions of colonialism, Islam and the tropics. I argue that these are inconsistent with ongoing decolonial moves

Topological‐defect‐featured order evolution of liquid crystals

open access: yesResponsive Materials, Volume 4, Issue 1, February 2026.
This review provides a comprehensive introduction to the recent advances in the topological‐defect‐featured order evolution of liquid crystal (LCs), including the stimulus‐driven dynamics of defects in nematic LCs, topological defect morphological transformation during phase transitions, advanced strategies for regulating and applications of ...
