Who pays for PFAS contamination? A comparative analysis of environmental liability in the US and Sweden

open access: yesReview of European, Comparative &International Environmental Law, EarlyView.
Abstract Environmental liability systems worldwide face mounting challenges addressing contamination from persistent chemicals, particularly when contamination spans decades and involves activities that were legal when performed. This article examines how the US and Sweden allocate responsibility for contaminated site remediation through their distinct

Does the European Union ‘Rule the World’? Competition Law Diffusion to Singapore and Hong Kong

open access: yesRegulation &Governance, EarlyView.
ABSTRACT This article examines why Singapore and Hong Kong adopted competition law by testing four diffusion mechanisms: coercion, competition, learning, and the Brussels Effect. Using structured process tracing and extensive archival evidence, it evaluates the distinct observable implications of each mechanism.

Divisibility Criteria for Class Numbers of Imaginary Quadratic Fields Whose Discriminant Has Only Two Prime Factors

open access: yesAbstract and Applied Analysis, 2012
We will prove a theorem providing sufficient condition for the divisibility of class numbers of certain imaginary quadratic fields by 2g, where g>1 is an integer and the discriminant of such fields has only two prime divisors.

The Impacts of Problem‐Posing Intervention on the Mathematical Proficiency of Undergraduate Developmental Mathematics Students' Developmental Mathematics

open access: yesSchool Science and Mathematics, EarlyView.
ABSTRACT This study investigates the impact of problem‐posing on the mathematical proficiency and engagement of 56 Developmental Mathematics (DM) students enrolled in a noncredit college mathematics course. Using a quasi‐experimental design, one of two existing classes was selected as the experimental group and received a 5‐week intervention focused on

Floquet stroboscopic divisibility in non-Markovian dynamics

open access: yesNew Journal of Physics, 2018
We provide a general description of a time-local master equation for a system coupled to a non-Markovian reservoir based on Floquet theory. This allows us to have a divisible dynamical map at discrete times, which we refer to as Floquet stroboscopic ...

Coordinated regulation of PIEZO2 by alternative splicing, post‐translational modification, membrane trafficking and protein partners

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Regulatory mechanisms such as alternative splicing, post‐translational modification, membrane trafficking, and protein interactions control channel gating, membrane abundance, and overall activity of PIEZO2. Proper regulation supports PIEZO2‐dependent proprioceptive, somatosensory, nociceptive, pruriceptive and interoceptive ...

The 3‐sparsity of Xn−1$X^n-1$ over finite fields of characteristic 2

open access: yesTransactions of the London Mathematical Society, Volume 13, Issue 1, December 2026.
Abstract Let q$q$ be a prime power and Fq$\mathbb {F}_q$ the finite field with q$q$ elements. For a positive integer n$n$, the polynomial Xn−1∈Fq[X]$X^n - 1 \in \mathbb {F}_q[X]$ is termed 3‐sparse over Fq$\mathbb {F}_q$ if all its irreducible factors in Fq[X]$\mathbb {F}_q[X]$ are either binomials or trinomials.

non-divisibility for abelian groups

open access: yesپژوهش‌های ریاضی, 2022
Introduction   In Throughout all groups are abelian. Suppose that G is a group and n is a positive integer. For a ∈ G, if we consider the solution of the equation nx = a in G, two subsets of G are proposed.

$p$-DIVISIBILITY FOR COHERENT COHOMOLOGY

open access: yesForum of Mathematics, Sigma, 2015
We prove that the coherent cohomology of a proper morphism of noetherian schemes can be made arbitrarily $p$-divisible by passage to proper covers (for a fixed prime $p$).
