AN ARGUMENT FOR NON‐AGREE‐DRIVEN MOVEMENT

open access: yesStudia Linguistica, Volume 78, Issue 2, Page 229-253, August 2024.
Abstract This paper argues for the occurrence of movement that is not the by‐product of an Agree relation in which a probe searches for a goal. The hypothesis that not all instances of movement might be feature‐driven was entertained in early Minimalism, but it has nevertheless become widely assumed that all instances of syntactic movement should be ...

Image Quantification for TSPO PET with a Novel Image-Derived Input Function Method

open access: yesDiagnostics, 2022
There is a growing interest in using 18F-DPA-714 PET to study neuroinflammation and microglial activation through imaging the 18-kDa translocator protein (TSPO).

Obsolescence and abortive innovations in variationist approaches to language change

open access: yesLanguage and Linguistics Compass, Volume 18, Issue 4, July/August 2024.
Abstract The focus of most variationist studies of linguistic change to date has been the emergence and increase of new forms. The opposing process—obsolescence, or the decline and loss of older variants—is less well understood. Addressing several calls for more attention to be paid to obsolescence and its properties, this article surveys case studies ...

Existence of Positive Solutions for Higher Order (p,q)-Laplacian Two-Point Boundary Value Problems

open access: yesInternational Journal of Differential Equations, 2013
We derive sufficient conditions for the existence of positive solutions to higher order (p,q)-Laplacian two-point boundary value problem, (-1)m1+n1-1[ϕp(u(2m1)(t))](n1)=f1(t,u(t),v(t)), t∈[0,1], (-1)m2+n2-1[ϕq(v(m2)(t))](2n2)=f2(t,u(t),v(t)), t∈[0,1], u ...

Global solutions and uniform boundedness of attractive/repulsive LV competition systems

open access: yesAdvances in Difference Equations, 2018
In this paper, we study global solutions to the following strongly coupled systems: {ut=∇⋅(D1∇u−χu∇v)+(a1−b1u−c1v)u,x∈Ω,t>0,0=D2Δv+(a2−b2u−c2v)v,x∈Ω,t>0, $$\textstyle\begin{cases} u_{t}=\nabla\cdot(D_{1} \nabla u -\chi u \nabla v)+(a_{1}-b_{1}u-c_{1}v)u,\

Irredundant bases for the symmetric group

open access: yesBulletin of the London Mathematical Society, Volume 56, Issue 5, Page 1788-1802, May 2024.
Abstract An irredundant base of a group G$G$ acting faithfully on a finite set Γ$\Gamma$ is a sequence of points in Γ$\Gamma$ that produces a strictly descending chain of pointwise stabiliser subgroups in G$G$, terminating at the trivial subgroup. Suppose that G$G$ is Sn$\operatorname{S}_{n}$ or An$\operatorname{A}_{n}$ acting primitively on Γ$\Gamma$,

Performance of electron reconstruction and selection with the CMS detector in proton-proton collisions at √s=8 TeV

open access: yes, 2015
The performance and strategies used in electron reconstruction and selection at CMS are presented based on data corresponding to an integrated luminosity of 19.7 inverse femtobarns, collected in proton-proton collisions at sqrt(s) = 8 TeV at the CERN LHC.

Overlap and effective size of the human CD8+ T-cell receptor repertoire

open access: yesScience Translational Medicine, 2010
Deep sequencing of the T cell receptor repertoires of seven healthy adults reveals that the adaptive immune system is far less diverse than expected and the person-to-person overlap is thousands of times larger.

Positive solutions for a system of $n$th-order nonlinear boundary value problems

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2011
In this paper, we investigate the existence, multiplicity and uniqueness of positive solutions for the following system of $n$th-order nonlinear boundary value problems \[\begin{cases} u^{(n)}(t)+f(t,u(t),v(t))=0 ...
