Nanomaterial sensing layers are employed for chemical and biological species detection in surface acoustic wave (SAW) sensors. The response characteristics of these sensors depend on the changes in the mechanical properties of the nanomaterials as the SAW propagates through the sensing layer. Knowledge of the mechanical properties is important to establish the stability and robustness of SAW se...

Abstract: The See-Saw mechanism provides a nice way to explain why neutrino masses are so much lighter than their charged lepton partners. It also provides a nice way to explain baryon asymmetry in our universe via the leptogenesis mechanism. In this talk we review leptogenesis and LHC physics in a See-Saw model proposed in 1989, now termed the Type III See-Saw model. In this model, SU(2)L trip...

Electronic nose (E-Nose) is one of the applications for surface acoustic wave (SAW) sensors. In general, the SAW sensor, as a gas sensor, consists of a passive element (LiNbO3 and IDTs) and an oscillator circuit, as shown in Fig. 1. For the E-Nose applications, a SAW sensor array is formed to construct the odor patterns for gas recognition. Because the oscillator frequency of each sensor is so ...

PURPOSE We tested the effects of a saw palmetto herbal blend in men with symptomatic benign prostatic hyperplasia (BPH) via a randomized, placebo controlled trial. MATERIALS AND METHODS We randomized 44 men 45 to 80 years old with symptomatic BPH into a trial of a saw palmetto herbal blend versus placebo. End points included routine clinical measures (symptom score, uroflowmetry and post-void...

Submitted for the DFD12 Meeting of The American Physical Society Surface Acoustic Wave (SAW) based Microfluidics for Particle and Droplet Manipulation YE AI, BABETTA L. MARRONE, Advanced Measurement Science, Los Alamos National Laboratory, Los Alamos, New Mexico 87545, USA — Acoustics has emerged as one of the most promising non-invasive techniques for particle and droplet manipulation in micro...

Saw palmetto is an herb used to treat the symptoms of benign prostatic hyperplasia. In vitro studies have found that saw palmetto inhibits growth of prostatic cancer cells and may induce apoptosis. To evaluate whether saw palmetto supplements are associated with a reduced risk of prostate cancer, we conducted a prospective cohort study of 35,171 men aged 50-76 yr in western Washington state. Su...

Surface acoustic wave (SAW) sensors are currently being investigated in a wide range in fields including physical, chemical and bio-sensing. The basic principle in a SAW sensor is the detection of changes in the propagation characteristics of the surface acoustic waves which are caused by perturbations on the active surface of the device. The most common situation is measuring the change in pro...

In this paper we describe how the Stepwise Adaptation of Weights (saw) technique can be applied in genetic programming. The saw-ing mechanism has been originally developed for and successfully used in eas for constraint satisfaction problems. Here we identify the very basic underlying ideas behind saw-ing and point out how it can be used for different types of problems. In particular, saw-ing i...

Due to further applications of Surface acoustic wave (SAW) devices in many applicable electronics and communications fields, modeling and simulation for these devices become more urgent in recent years. SAW devices can found in frequency range from 10 MHz to several GHz. It can found in RF, IF, stages of mobile. SAW devices convert mechanical waves to electrical and vice versa through IDT. This...
