Mesoscale wind fields have been determined for a mature hurricane with high spatial and temporal resolution, continuity, and coherency. These wind fields, near the tropopause in the inner core and at low levels inside the eye, allow the evolution of mesoscale storm features to be observed. Previously, satellite-derived winds near hurricanes have been determined only at some distance from the ey...

In FT-ICLAS, the aim is to improve the absorption detection sensitivity. The experiment combines IntraCavity Laser Absorption Spectroscopy (ICLAS) with FTIR spectroscopy. ICLAS is a well known instrumental technique in which a sample is inserted in a cell placed inside a broadband, multimode laser cavity. The laser is operating in pulsed mode and intracavity absorption rises as the laser wave b...

Structure of the cortex The adult cerebral cortex is a complex convoluted multilayered structure averaging around 2.3mm thick, but thinner (≤ 2mm) in the depths of the sulcal folds and thicker (3-4mm) at the crown of the gyri. It is typically divided into 6 layers depending upon the constituent cell types. On examination a section of the cortex, it is seen to consist of alternating white and gr...

Background: High-resolution magic angle proton magnetic resonance spectroscopy (HR 1H MAS MRS) provides a broad metabolic mapping of intact tumor samples and allows for microscopy investigations of the samples after spectra acquisition. Experimental studies have suggested that the method can be used for detection of apoptosis, but this has not been investigated in a clinical setting so far. We ...

This paper investigates high-resolution reconstructions from eeciently sampled data in parallel-beam tomography, in particular local tomography. A class of sampling schemes is deened and characterized, and it is shown that the standard scheme and the interlaced scheme of Cormack are most promising. An error analysis for the ltered backprojection algorithm for both global and local tomography is...

In this paper, we propose a method to improve the spatial resolution of video sequences. Our approach is inspired by previous image hallucination work [12]. There are two main contributions of the proposed method. First, the information from cameras with different spatial-temporal resolutions is combined in our framework. This is achieved by constructing training dictionary using the high resol...

Over the past decade, significant advances were made in the research, diagnosis, and treatment of cardiovascular diseases. Such progress was in every sphere of cardiology that includes non-invasive, minimally invasive, and invasive technologies. Interpretive electrocardiography, cardiac pacemakers, cardiac stents, and angioplasty are some areas where the progress has been significant. Non-invas...

Methods used in obtaining high resolution in autoradiography, with special emphasis on the technique of electron microscopic autoradiography, are described, together with control experiments designed to establish the optimum conditions or procedures. On the basis of these experiments the emulsion selected was Ilford L-4, with a crystal size slightly larger than 0.1 micron. It is applied to the ...
