Tradeoffs between elemental homeostasis and growth govern freshwater phytoplankton responses to salinization

Limnology and Oceanography, EarlyView.
Abstract Anthropogenic salinization resulting from road salt application can degrade aquatic environments by altering the structure and function of phytoplankton communities, ultimately reducing flows of resources through aquatic food webs. However, physiological mechanisms underlying taxon‐specific responses to salinization are often poorly linked to ...

Variable phenology but consistent loss of ice cover on 1213 Minnesota lakes

Limnology and Oceanography Letters, EarlyView.
Abstract Lake ice cover is declining globally with important implications for lake ecosystems. Ice loss studies often rely on small numbers of lakes with long‐term data. We analyzed variation and trends in ice cover phenology from 1213 lakes over 74 yr (1949–2022) in Minnesota (USA), during which ice cover duration declined at a rate of 2 d per decade (

Solvent and Ion‐Mediated Behavior of a Thermoresponsive Brush: Specific Ion Effects in Methanol‐Water Electrolytes

Macromolecular Rapid Communications, EarlyView.
The manifestation of specific ion effects in methanol‐water mixtures on polymer brush exemplars is explored. Spectroscopic ellipsometry and neutron reflectometry revealed solvent‐driven LCST changes in a thermoresponsive brush, which is also readily influenced by the presence of electrolytes.

Piecewise automatic groups

Duke Mathematical Journal, 2006
We introduce a notion of a piecewise automatic group. Among these groups we describe a new class of groups of intermediate growth. We show that for any function f:N→N, there exists a finitely generated torsion group of intermediate growth G for which the Folner function satisfies FolG,S(n)≥f(n) for some generating set S and all sufficiently large n.

A highly accurate numerical method for solving boundary value problem of generalized Bagley‐Torvik equation

Mathematical Methods in the Applied Sciences, EarlyView.
A highly accurate numerical method is given for the solution of boundary value problem of generalized Bagley‐Torvik (BgT) equation with Caputo derivative of order 0<β<2$$ 0<\beta <2 $$ by using the collocation‐shooting method (C‐SM). The collocation solution is constructed in the space Sm+1(1)$$ {S}_{m+1}^{(1)} $$ as piecewise polynomials of degree at ...

Coherence of Coupling Conditions for the Isothermal Euler System

Mathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT We consider an isothermal flow through two pipes. At the junction, the flow is possibly modified by some devices, such as valves, compressors, and so on, or by the geometry of the junction; coupling conditions between the traces of the flow must be given.

Coordinated active and reactive power management for enhancing PV hosting capacity in distribution networks

IET Renewable Power Generation, EarlyView., 2023
A two‐stage operational planning model is developed for PV hosting capacity problems in the distribution network, which considers both operational practice by enhancement of HC of PV and economical operational limits by minimization of total planning cost.

A Stable Hybridized Discontinuous Galerkin Method for Solving Some Nonlinear m$$ m $$‐Component Reaction–Diffusion Systems

Mathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT In this paper, we present a stable numerical scheme for solving two‐dimensional m$$ m $$‐component reaction–diffusion systems. The proposed approach utilizes the backward Euler method for temporal discretization and the hybridized discontinuous Galerkin (HDG) method for spatial discretization.

Implementation of a novel pencil beam scanning Bragg peak FLASH technique to a commercial treatment planning system

Medical Physics, EarlyView.
Abstract Background Ultra‐high dose rate, or FLASH, radiotherapy has shown promise in preclinical experiments of sparing healthy tissue without compromising tumor control. This “FLASH effect” can compound with dosimetric sparing of the proton Bragg peak (BP) using a method called Single Energy Pristine Bragg Peak (SEPBP) FLASH.
