Effects of chain topology on polymer dynamics: Bulk melts

JS Shaffer - The Journal of chemical physics, 1994 - pubs.aip.org
We introduce a new lattice‐based Monte Carlo model of polymer dynamics in which the
polymer chain topology can be altered without perturbing any static properties or the local …

The service life of large aluminum electrolytic capacitors: effects of construction and application

JL Stevens, JS Shaffer… - Conference Record of the …, 2001 - ieeexplore.ieee.org
Large aluminum electrolytic capacitors are usually selected by considering factors such as
cost effectiveness (more ripple current or capacitance per dollar), space effectiveness (less …

Effects of chain topology on polymer dynamics: Configurational relaxation in polymer melts

JS Shaffer - The Journal of chemical physics, 1995 - pubs.aip.org
We report computer simulations of chain dynamics in monodisperse, linear polymer melts
using a model which allows the dynamical effects of chain topology to be isolated from the …

Optimal immunization cocktails can promote induction of broadly neutralizing Abs against highly mutable pathogens

JS Shaffer, PL Moore, M Kardar… - Proceedings of the …, 2016 - National Acad Sciences
Strategies to elicit Abs that can neutralize diverse strains of a highly mutable pathogen are
likely to result in a potent vaccine. Broadly neutralizing Abs (bnAbs) against HIV have been …

Deepwater demersal fish community collapse in Lake Huron

…, TP O'Brien, CS Kiley, JS Schaeffer - Transactions of the …, 2008 - Taylor & Francis
Long-term fish community surveys were carried out in the Michigan waters of Lake Huron
using bottom trawls from 1976 to 2006. Trends in abundance indices for common species (…

Angler-caught piscivore diets reflect fish community changes in Lake Huron

EF Roseman, JS Schaeffer, E Bright… - Transactions of the …, 2014 - Taylor & Francis
Examination of angler-caught piscivore stomachs revealed that Lake Trout Salvelinus
namaycush, Chinook Salmon Oncorhynchus tshawytscha, and Walleyes Sander vitreus altered …

Dynamics of poly (methyl methacrylate) chains adsorbed on aluminum surfaces

JS Shaffer, AK Chakraborty - Macromolecules, 1993 - ACS Publications
We present a stochastic model for the dynamics of poly (methyl methacrylate)(PMMA) chains
adsorbed on an aluminum surface. The model is able to investigate the relevant length …

Environmental and ecological conditions surrounding the production of large year classes of walleye (Sander vitreus) in Saginaw Bay, Lake Huron

DG Fielder, JS Schaeffer, MV Thomas - Journal of Great Lakes Research, 2007 - Elsevier
… (JS Schaeffer, USGS, unpublished data). Alternatively, managers could assume the average
annual mortality rate of 71%. The ability of alewives to affect future percid production in …

Electron-spin-resonance study of manganese-doped spinel

JS Shaffer, HA Farach, CP Poole Jr - Physical Review B, 1976 - APS
An electron-spin-resonance study of manganese-doped synthetic spinel samples (Mg Al 2
O 4) produced spectra with six sharp main lines corresponding to the hyperfine components …

Invasion history, proliferation, and offshore diet of the round goby Neogobius melanostomus in western Lake Huron, USA

JS Schaeffer, A Bowen, M Thomas… - Journal of Great Lakes …, 2005 - Elsevier
We used data from three trawl surveys during 1996–2003 to document range expansion,
population trends, and use of offshore habitats by round gobies in the US waters of Lake Huron…
