Combinatorics and Boson normal ordering: A gentle introduction

, 2007
We discuss a general combinatorial framework for operator ordering problems by applying it to the normal ordering of the powers and exponential of the boson number operator.

Evidence for increased background neural noise in migraine with aura: Hyperactive but not hyperresponsive

Headache: The Journal of Head and Face Pain, EarlyView.
Abstract Objective This study had two aims: (1) to investigate the contrast gain in migraine and compare it to that in photosensitive epilepsy; (2) to explore any effects of colored spectacles (precision ophthalmic tints [POT]) on contrast gain. Background Individuals with migraine with aura (MA) typically show high amplitude electrophysiological ...

Normal Order: Combinatorial Graphs

, 2003
A conventional context for supersymmetric problems arises when we consider systems containing both boson and fermion operators. In this note we consider the normal ordering problem for a string of such operators.

Expert Memories: The Professional Construction of the Past and the Mnemonic Making of Occupations

Journal of Management Studies, EarlyView.
Abstract This article introduces the special issue on occupations and memory in organizations. To foster increasing collaboration from scholars from both fields, we offer a general argument connecting memory and occupations on two levels. At the societal level, we show how memory experts, such as historians, archivists, and museologists, have played a ...

On the 2-adic order of Stirling numbers of the second kind and their differences [PDF]

Discrete Mathematics & Theoretical Computer Science, 2009
Let $n$ and $k$ be positive integers, $d(k)$ and $\nu_2(k)$ denote the number of ones in the binary representation of $k$ and the highest power of two dividing $k$, respectively.

Eligible but Not Entitled: The Distinctiveness of Non‐Entitlement Policy Designs at the Frontline

Social Policy &Administration, EarlyView.
ABSTRACT This paper explores the distinctive dynamics of entitlement versus non‐entitlement social programmes, focusing on how this distinction influences frontline workers' management of access to social provisions. While much of the existing literature emphasises the macro‐level impacts of these alternative policy designs, this study focuses on their
