This paper reports the correlation between film thickness, nanostructure and DC electrical properties of copper thin films deposited by PVD method on glass substrate. X-ray diffraction (XRD) and atomic force microscopy (AFM) were used for crystallography and morphology investigation, respectively. Resistivity was measured by four point probe instrument, while a Hall effects measurement system w...

BACKGROUND Tumor thickness has been shown in oral tongue squamous cell carcinoma (OTSCC) to be a predictor of cervical metastasis. The postoperative histological measurement is certainly the most accurate, but it would be of clinical interest to gain this information prior to treatment planning. This retrospective study aimed to compare the tumor thickness measurement between preoperative, CT s...

This paper presents a mathematical model for the vibration analysis of a three-component piezoelectric force sensor. The cubic theory of weakly nonlinear electroelasticity is applied to the model for describing the electromechanical coupling effect in the piezoelectric sensing elements which operate in thickness-shear and thickness-stretch vibration modes. Hamilton's principle is used to derive...

purpose : to describe the macular thickness map of iranian adult with normal retinal status as measured by cirrus’ optical coherence tomography (oct) instrument methods : in this cross-sectional study, one eye of subjects with normal ocular examination and retinal status of at least one eye were recruited. the 512×128-scan pattern and scan area of 6×6 mm2 with software version 4 protocol in cir...

Adult cerebral cortical structure is thought to be statically maintained over short intervals. This view is based on group average findings but has never been studied at the individual level. This issue was examined with an unconventional longitudinal magnetic resonance imaging design which measured hemispheric mean cortical thickness of an adult man repeatedly at week intervals over 6 months. ...

Traditional broadband transmission method for measuring acoustic dispersion requires the measurements of the sound speed in water, the thickness of the specimen, and the phase spectra of two transmitted ultrasound pulses. When the sound speed in the specimen is significantly different from that in water, the overall uncertainty of the dispersion measurement is generally dominated by the uncerta...

Background O-30: The Correlation between Myometrial Thickness and In Vitro Fertilization/ Intracyto- Plasmic Sperm Injection (IVF/ ICSI) Outcomes MaterialsAndMethods In this prospective cohort study, 453 infertile women undergoing IVF-ET/ICSI cycles without any obvious pathology of uterine were enrolled. Trans-vaginal ultrasounds were conducted on days 2-4 of the cycle (menstrual phase) precedi...

A novel technique to measure in situ, simultaneously, temperature and thin film thickness during semiconductor processing is described in this paper. The measurement technique is based on the principle propagating in a silicon wafer is a function of both the that the velocity of an ultrasonic Lamb wave wafer temperature and the thin film coating on the wafer surface. We are able to btain the pr...

OBJECTIVES We aimed to determine the precision of the Laplacian approach for cortical thickness measurement due to changes in computational and acquisition parameters. We compared these results to two other methods widely used in clinical research using brain MRI data. MATERIALS AND METHODS Brain MRI scans were obtained in 10 healthy adults using three different sets of acquisition parameters...
