Electro-Thermo-Mechanical Model for Bulk Acoustic Wave Resonators

November 30, 2013
Author(s)
Eduard Rocas, Juan C. Collado Gomez, Jordi Mateu, Nathan D. Orloff, James C. Booth, Robert Aigner
We present the electro-thermo-mechanical constitutive relations, expanded up to the third order, for a BAW resonator. The relations obtained are implemented into a circuit model, which is validated with extensive linear and nonlinear measurements. The

Preface: Ubiquitous Robotics (UBIROBOTS): Workshop at the UBICOMP 2012 Conference

November 30, 2013
Author(s)
Craig I. Schlenoff, Edson Prestes, Abdelghani Chibani, Yacine Amirat
Ubiquitous robots (UBIROBOTS) are smart software or physical service providers within ambient intelligence environments. The integration of these robots within cloud computing and ubiquitous computing technologies will enhance our daily lives. Ubiquitous

Hybrid Detectors

November 29, 2013
Author(s)
Sergey V. Polyakov, Alan L. Migdall, Franco N. Wong, Ivo P. Degiovanni, Ian Walmsley, Hendrik B. Coldenstrodt-Ronge
We present an overview of e orts to improve photon-counting detection systems through the use of hybrid detection techniques such as spatial- and time-multiplexing of conventional detectors, and frequency up-conversion. We review the basic operation for

Photomultiplier tubes

November 29, 2013
Author(s)
Sergey V. Polyakov
Photomultiplier tubes (PMTs), also known as photomultipliers, are remarkable devices. While a PMT was the rst device to detect light at the single photon level, invented more than 80 years ago, they are widely used to this day, particularly in biological

Photon statistics, measurements, and measurements tools

November 29, 2013
Author(s)
Martin J. Stevens
Single-photon generation and detection is at the forefront of modern optical physics research. This book is intended to provide a comprehensive overview of the current status of single- photon techniques and research methods in the spectral region from the

Single-Photon Sources and Detectors Book: Chapter 1: Introduction

November 29, 2013
Author(s)
Joshua C. Bienfang, Jingyun Fan, Alan L. Migdall, Sergey V. Polyakov
In the beginning there was light. And it was good. Not long thereafter people began to look for a comprehensive understanding of its nature. While the publication record starts o a little spotty, in the fth century BC the Greek philosopher Empedocles

Bounding Defaults in Egress Models

November 28, 2013
Author(s)
Steve M. Gwynne, Erica D. Kuligowski, Michael Spearpoint, Enrico Ronchi
The developers of egress models are in a difficult position. It is in their interest to develop models that are quick and easy to employ and at the same time to reduce accidental model misuse. While default values enables out-of-the-box use of models

Coexposure to Phytoestrogens and Bisphenol a Mimics Estrogenic Effects in an Additive Manner

November 27, 2013
Author(s)
Anne Katchy, Caroline Pinto, Philip Jonsson, Trang Nguyen-Vu, Marchela Pandelova, Anne Riu, Karl-Werner Schramm, Daniel Samarov, Jan-Ake Gustafsson, Maria Bondesson, Cecilia Williams
Endocrine-disrupting chemicals (EDC) are abundant in our environment. A number of EDCs, including bisphenol A (BPA) can bind to the estrogen receptors, ERα and ERβ, and may contribute to estrogen-linked diseases such as breast cancer. Early-exposure is of

Lead-free and Lead-Based ABO 3 Perovskite Relaxors with Mixed-Valence A-Site and B-Site Disorder: A Comparative Neutron Scattering Structural Study of (NaYd1/2^Bi 1/2)TiO d3^ and Pb(MgYd1/3^Nb 2/3 )O 3

November 27, 2013
Author(s)
Wenwei Ge, Christopher P. Devreugd, Daniel Phelan, Qinhui Zhang, Muhtar Ahart, Jiefang Li, Haosu Luo, Lynn A. Boatner, Dwight Viehland, Peter M. Gehring
We report the results of neutron elastic scattering measurements between -250°C and 620°C on the lead-free relaxor Na 1/2Bi 1/2TiO 3 (NBT). Strong, anisotropic, elastic diffuse scattering intensity decorates the (100), (110), (111), (200), (220), and (210)
