Monte Carlo studies of quantum and classical annealing on a double well

We present results for a variety of Monte Carlo annealing approaches, both classical and quantum, benchmarked against one another for the textbook optimization exercise of a simple one-dimensional double well. In classical (thermal) annealing, the dependence upon the move chosen in a Metropolis scheme is studied and correlated with the spectrum of the associated Markov transition matrix. In quantum annealing, the path integral Monte Carlo approach is found to yield nontrivial sampling difficulties associated with the tunneling between the two wells. The choice of fictitious quantum kinetic energy is also addressed. We find that a "relativistic" kinetic energy form, leading to a higher probability of long real-space jumps, can be considerably more effective than the standard nonrelativistic one.

On Theft: Teaching Poetry Composition to Undergraduates

This chapter discusses the potential uses of both found poetry and imitiation poetry as teaching material for undergraduate creative poetry students.

A Measurements Based Comparison of New and Classical Models Used to Characterize Fading in Body Area Networks

In this paper we compare a number of the classical models used to characterize fading in body area networks (BANs) with the recently proposed shadowed ț–ȝ fading model. In particular, we focus on BAN channels which are considered to be susceptible to shadowing by the human body. The measurements considered in this study were conducted at 2.45 GHz for hypothetical BAN channels operating in both anechoic and highly reverberant environments while the person was moving. Compared to the Rice, Nakagami and lognormal fading models, it was found that the recently proposed shadowed ț௅μ fading model provided an enhanced fit to the measured data.

Introducing Students to Pre-Nineteenth-Century Poetry in the Language Classroom

We as language instructors are tasked with preparing students to transition from language to literature courses. The shorter length of many poems makes them ideal for presentation in the language classroom, where the acquisition of communicative competence is the priority. Introductory and intermediate textbooks’ poetry offerings, however, are frequently drawn from a canon of poems by only a few nineteenth- and twentieth-century authors (Verlaine, Apollinaire, Prévert) and fail to expose students to broader aspects of French literature. This article offers strategies for presenting pre-nineteenth-century poetry to first- and second-year students of French using dizains from Scève’s Délie as examples.
