Quantifying community keystoneness in metacommunities under disturbance

open access: yesOikos, EarlyView.
Understanding how metacommunities respond to natural and anthropogenic disturbances is a key objective in ecology. In this study, we introduce an analytical framework to identify communities whose extirpation triggers stronger (hereafter keystone communities) or weaker (hereafter idle communities) cascading effects on extinction and colonization events

Bifurcation from infinity and nodal solutions of quasilinear elliptic differential equations

open access: yesElectronic Journal of Differential Equations, 2014
In this article, we establish a unilateral global bifurcation theorem from infinity for a class of $N$-dimensional p-Laplacian problems. As an application, we study the global behavior of the components of nodal solutions of the problem ...

2‐Adic Quantum Mechanics, Continuous‐Time Quantum Walks, and the Space Discreteness

open access: yesFortschritte der Physik, EarlyView.
Abstract The authors show that a large class of 2‐adic Schrödinger equations is the scaling limit of certain continuous‐time quantum Markov chains (CTQMCs). Practically, a discretization of such an equation gives a CTQMC. As a practical result, new types of continuous‐time quantum walks (CTQWs) on graphs using two symmetric matrices are constructed ...

Pirana and Integrated PMX Tools, a Workbench for NONMEM, NLME, pyDarwin, and RsNLME

open access: yesCPT: Pharmacometrics &Systems Pharmacology, EarlyView.
ABSTRACT Keizer initially described Pirana as a workbench designed to streamline management of NONMEM modeling, visualization, and analysis. Initial versions of Pirana integrated tools included NONMEM and PSN. As new tools have become available to pharmacometricians, new capabilities have been added to Pirana. These capabilities include: Integration of

Asymptotic behavior of solutions for some nonlinear partial differential equations on unbounded domains

open access: yesElectronic Journal of Differential Equations, 2001
We study the asymptotic behavior of positive solutions $u$ of $$ -Delta_p u(x) = V(x) u(x)^{p-1}, quad p>1; x in Omega,$$ and related partial differential inequalities, as well as conditions for existence of such solutions.

Continuous‐Time Markov Population PK/PD Modeling of Longitudinal EASI Categorical Score in Atopic Dermatitis Treated With Rocatinlimab, an Anti‐OX40 Monoclonal Antibody

open access: yesCPT: Pharmacometrics &Systems Pharmacology, EarlyView.
ABSTRACT Rocatinlimab (AMG 451/KHK4083) is a potential T‐cell rebalancing therapy that inhibits and reduces the number of pathogenic T cells by targeting the OX40 receptor; it is associated with a progressive and sustained response for patients with moderate‐to‐severe atopic dermatitis (AD).
