Social agency and the dynamics of prehistoric technology

MA Dobres, CR Hoffman - Journal of archaeological method and theory, 1994 - Springer
Technology is not only the material means of making artifacts, but a dynamic cultural phenomenon
embedded in social action, worldviews, and social reproduction. This paper explores …

A highly enantio-and diastereoselective molybdenum-catalyzed asymmetric allylic alkylation of cyanoesters

BM Trost, JR Miller, CM Hoffman Jr - Journal of the American …, 2011 - ACS Publications
An efficient molybdenum-catalyzed asymmetric allylic alkylation (Mo-AAA) of cyanoester
nucleophiles is reported. A number of highly functionalized branched cyanoesters containing a …

[HTML][HTML] Goal-directed fluid therapy in the perioperative setting

…, Y Tong, K Belani, RD Urman, C Hoffman… - Journal of …, 2019 - journals.lww.com
Improvement in patient outcomes has become a significant consideration with our limited
resources in the surgical setting. The implementation of enhanced recovery pathway protocols …

Geodesics in first passage percolation

C Hoffman - 2008 - projecteuclid.org
We consider a wide class of ergodic first passage percolation processes on ℤ 2 and prove
that there exist at least four one-sided geodesics as We also show that coexistence is …

UV-cured eutectic gel polymer electrolytes for safe and robust Li-ion batteries

…, S Langevin, B Tan, AW Freeman, C Hoffman… - Journal of materials …, 2020 - pubs.rsc.org
Gel polymer electrolytes (GPEs) hold great promise for next-generation Li-ion batteries as
they combine the high ionic conductivity and facile transport properties of liquid electrolytes …

The fundamental group of random 2-complexes

E Babson, C Hoffman, M Kahle - Journal of the American Mathematical …, 2011 - ams.org
We study Linial-Meshulam random $2 $-complexes $ Y (n, p) $, which are $2 $-dimensional
analogues of Erdős-Rényi random graphs. We find the threshold for simple connectivity to …

Coexistence for Richardson type competing spatial growth models

C Hoffman - 2005 - projecteuclid.org
We study a large family of competing spatial growth models. In these models the vertices in
ℤ d can take on three possible states {0,1,2}. Vertices in states 1 and 2 remain in their states …

Anomalous heat-kernel decay for random walk among bounded random conductances

N Berger, M Biskup, CE Hoffman… - Annales de l'IHP …, 2008 - numdam.org
On considère la marche aléatoire aux plus proches voisins dans Zd, d≥ 2, dont les transitions
sont données par un champ de conductances aléatoires bornées ωxy∈[0, 1]. La loi de …

Mixing times of the biased card shuffling and the asymmetric exclusion process

I Benjamini, N Berger, C Hoffman, E Mossel - Transactions of the American …, 2005 - ams.org
Consider the following method of card shuffling. Start with a deck of $ N $ cards numbered 1
through $ N $. Fix a parameter $ p $ between 0 and 1. In this model a “shuffle” consists of …

Spectral gaps of random graphs and applications

C Hoffman, M Kahle, E Paquette - International Mathematics …, 2021 - academic.oup.com
We study the spectral gap of the Erdős–Rényi random graph through the connectivity
threshold. In particular, we show that for any fixed $\delta> 0$ if $$\begin{equation*} p \geq \frac{(1/…
