Narrow band photoacoustics ~laser ultrasonics! are used to characterize the properties of free-standing nanometer-sized thin films. Photoacoustic generation is achieved by use of a microchip laser which deposits pulsed laser energy in the form of a spatially periodic source on the structure. The resulting narrow band ultrasonic modes are monitored using a Michelson interferometer. By varying th...

PURPOSE The one-year effectiveness of transdermal nicotine patches versus placebo patches for smoking cessation based on continuous or sustained abstinence was studied. METHODS A literature search of MEDLINE (PubMed), EMBASE, and the Cochrane Central Register of Controlled Trials up to April 2006 was conducted. Articles containing relevant keywords were reviewed by two evaluators independentl...

Introduction: Millimetre-wave fibre wireless applications [1] could profit from a small antenna that can be fully integrated with the microwave and optical components of the system. This can lead to smaller and more cost-effective fibre-fed antenna units. Active integrated antennas [2] are another application that could benefit from a directly integrated antenna. Printed antennas are the obviou...

In this paper, a compact SISO (Single-Input Single-Output) antenna with novel slotted-decahedral geometry is presented. The design was performed using full-wave simulator (FWS). A decahedral patch an eight-pointed star-shaped slot and two rectangular grooves the main characteristic of proposed radiator. decagon shape, slot, grooves, separate section give rise to radiation. operates from 23.1 29...

Exposure to faces biases perceptions of subsequently viewed faces such that normality judgments of similar faces are increased. Simultaneously inducing such an aftereffect in opposite directions for two groups of faces might indicate discrete responding of the neural populations coding for those groups. Here we show such "category contingent" aftereffects following exposure to faces differing i...

This paper presents a novel narrowband microstrip patch antenna for radar application. The proposed antenna consists of rectangular radiating patch which provides a narrowband behavior and relatively good impedance matching working in the band of 3-12 GHz. A parametric study is performed on three different antenna structures. The measured results give three narrow band stable signal transmissio...
