DESCRIPTION A 28-year-old man presents 5 months after a table saw crush injury to the thumb and the index finger of the right hand. Initially, he required thumb interphalangeal joint arthrodesis and ray amputation of the index finger. Postoperatively, the patient noted scarring and gradual contracture of the first web space causing pain with movement and significant restriction in the hand func...

A novel wireless and passive surface acoustic wave (SAW) based temperature-compensated vibration sensor utilizing a flexible Y-cut quartz cantilever beam with a relatively substantial proof mass and two one-port resonators is developed. One resonator acts as the sensing device adjacent to the clamped end for maximum strain sensitivity, and the other one is used as the reference located on clamp...

In the paper a feasibility study on the use of surface acoustic wave (SAW) vibration sensors for electronic warning systems is presented. The system is assembled from concatenated SAW vibration sensors based on a SAW delay line manufactured on a surface of a piezoelectric plate. Vibrations of the plate are transformed into electric signals that allow identification of the sensor and localizatio...

We report the use of focused surface acoustic waves SAWs generated on 128° rotated Y-cut X-propagating lithium niobate LiNbO3 for enhancing the actuation of fluids and the manipulation of particle suspensions at microscale dimensions. In particular, we demonstrate increased efficiency and speed in carrying out particle concentration/separation and in generating intense micromixing in microliter...

A rapid particle concentration method in a sessile droplet has been developed using asymmetric surface acoustic wave (SAW) propagation on a substrate upon which the droplet is placed. Due to the asymmetry in the SAW propagation, azimuthal bulk liquid recirculation (acoustic streaming) is generated. Once the local particle concentration is sufficiently high within a particular streamline of the ...

The next generation of X-ray diffraction optics will benefit from crystal surfaces with very high quality (extremely flat and strain-free), but knowledge on how to achieve such surfaces, and how surface imperfections affect the diffraction properties, is sparse in the literature. As a first step toward initializing a systematic study on this topic, we evaluate in this paper the surface quality ...

2. Let Q(X,Y ) be some joint distribution. Suppose (X, Y ) = (X1, Y1), . . . , (Xn, Yn) iid ∼ Q0(X,Y ) = Q(X)Q(Y ), where Q(X) and Q(Y ) are the marginal distributions corresponding to the joint distribution Q(X,Y ). In other words, Xi and Yi are independent. We are interested in the probability that (X, Y ) appear to be depdendent or jointly distributed according to Q(X,Y ). In last lecture, w...

We introduce an image segmentation algorithm, called GC(sum)(max), which combines, in novel manner, the strengths of two popular algorithms: Relative Fuzzy Connectedness (RFC) and (standard) Graph Cut (GC). We show, both theoretically and experimentally, that GC(sum)(max) preserves robustness of RFC with respect to the seed choice (thus, avoiding "shrinking problem" of GC), while keeping GC's s...
