This paper presents a general model for calculating the density of states and the Cooper pair potential in proximised superconducting biand trilayer films. It is valid for any kind of bilayer S1-S2, whatever the quality of the materials S1 and S2, the quality of the S1-S2 interface and the layer thicknesses. The trilayer model is valid for a thin S3 layer, whereas the other two layers have arbi...

The measurement of the thicknesses of layers is important for the quality assurance of industrial coating systems. Current measurement techniques only provide a limited amount of information. Here, we show that spectral domain Line Field (LF) Optical Coherence Tomography (OCT) is able to return to the user a cross sectional B-Scan image in a single shot with no mechanical moving parts. To relia...

BACKGROUND To explore the changes in thickness in different areas and layers of the macula under different refractive conditions. METHODS Consecutive participants were enrolled in the study. Optical coherence tomography (OCT) images were obtained using a spectral-domain system. We studied the relationships of the full, inner and outer retinal thicknesses of the fovea, parafovea and perifovea ...

PURPOSE The goal of this cross-sectional observational study was to quantify the pattern-shift visual evoked potentials (VEP) and the thickness as well as the volume of retinal layers using optical coherence tomography (OCT) across a cohort of Parkinson's disease (PD) patients and age-matched controls. METHODS Forty-three PD patients and 38 controls were enrolled. All participants underwent a...

PURPOSE To characterize qualitative and quantitative features of the choroid in normal eyes using enface swept-source optical coherence tomography (SS-OCT). METHODS Fifty-two eyes of 26 consecutive normal subjects were prospectively recruited to obtain multiple three-dimensional 12 x 12 mm volumetric scans using a long-wavelength high-speed SS-OCT prototype. A motion-correction algorithm merg...

hedera helix  is widely used to treat bronchial asthma for many years. however, effects of this herb on lung histopathology is still far from clear. we aimed to determine the effect of oral administration of hedera helix on lung histopathology in a murine model of chronic asthma. balb/c  mice  were  divided  into  four  groups;   i  (placebo),  ii  (hedera  helix), iii (dexamethasone) and iv (c...

The structural characteristics of the outer retinal layers in primary open angle glaucoma (POAG) are still controversial, and these changes, along with those in the inner retinal layers, could have clinical and/or pathophysiological significance. A custom-built ultra-high resolution optical coherence tomography (UHR-OCT) combined with an automated segmentation algorithm can image and measure th...

The design and construction of the trackbed support structure is extremely important for controlling track settlement, dynamic deflection, and the overall quality of the trackbed. These factors largely influence the long-term performance of the track relative to maintaining adequate geometric features for efficient and safe train operations. Performance-based design methods provide design crite...

We have investigated the magnetism of NiFe/CoO/Co trilayers with different CoO spacer thicknesses. The dependence of the coercivity (Hc) and exchange bias field (Hex) on the CoO thicknesses indicated that different pinning strengths from the CoO were acting on the top NiFe and bottom Co layers, respectively. DC susceptibility indicated the different interlayer coupling energies and showed that ...
