Measurement of Autogenous Pressure and Dissociated Species during the Thermolysis of Mesitylene for the Synthesis of Monodispersed, Pure, Paramagnetic Carbon Particles (2008)

Two reaction parameters are important for the synthesis of entirely monodispersed, pure, paramagnetic spherical carbon particles. The experimental setup is developed to measure in situ autogenous pressure as a function of temperature during the thermolysis of mesitylene in a closed reactor. In situ mass spectrometry analyzed the dissociated species during the heating cycle of mesitylene as a function of temperature. The morphology, structure, composition, and magnetic properties of the as-prepared spherical carbon particles are characterized by using SEM, XRD, Raman spectroscopy, EDX, CHNS analysis, and EPR.
Eddy-current inspection for steam-generator tubing program. Quarterly progress report for period ending June 30, 1978 (1978)

Eddy-current methods provide the best in-service inspection of steam generator tubing, but present techniques can produce ambiguity because many independent variables affect the signals. The current development program will use mathematical models and develop or modify computer programs to design optimum probes, instrumentation, and techniques for multifrequency, multiproperty examinations. Interactive calculations and experimental measurements are made with the use of modular eddy-current instrumentation and a minicomputer. These establish the coefficients for the complex equations that define the values of the desired properties (and the attainable accuracy), despite changes in other significant variables. The final eddy-current instruments will contain on-board microcomputers for real-time data processing and interpretation. Progress is being made in adding to the computer programs parameters for different circuit designs. Programs that allow direct interfacing between a minicomputer and the eddy-current instrument have been written and tested on preliminary tubing. The first modular three-frequency instrument has been constructed. We are continuing to acquire tubing standards and specimens for developing and checking the instrumentation and techniques.
EXTRACELLULAR POLYSACCHARIDES OF AZOTOBACTER VINELANDII (1964)

Cohen, Gary H. (University of Vermont, Burlington), and Donald B. Johnstone. Extracellular polysaccharides of Azotobacter vinelandii. J. Bacteriol. 88:329-338. 1964.-Extracellular polysaccharides synthetized by Azotobacter vinelandii strains 155, 102, and 3A were shown to be carboxylic acid heteropolysaccharides of apparent high molecular weight. Cells were grown in a nitrogen-free, mineral broth medium with 2% sucrose. Extracellular slime was recovered by centrifugation and purified by repeated alcohol precipitation and Sevag deproteinization. Capsular polysaccharide was recovered from washed cells by mild alkaline digestion. Methods of isolation and purification appeared to provide polysaccharide showing no evidence of heterogeneity when examined by chemical and physical methods. Infrared analysis of purified slime from the three strains suggested fundamental structural similarities. Colorimetric, paper chromatographic, and enzymatic analyses on both intact and acid-hydrolyzed slime polysaccharide indicated that the polymers contained in common galacturonic acid, [alpha] d-glucose, and rhamnose at a ratio of approximately 43:2:1, as well as a hexuronic acid lactone, probably mannurono-lactone. However, as shown by chemical and infrared analysis, minor differences did exist; namely, slime from strain 155 and 102 contained o-acetyl groups, whereas slime from strain 3A contained none. A sialic acid-like component (1.5% of dry weight of the polysaccharide, calculated as N-acetyl neuraminic acid), was found only in the slime of strain 155. Capsular polysaccharide composition closely resembled that for slime. It is of interest that the major slime components were identical whether the energy source provided for the cells was sucrose, glucose, fructose, or ethanol.

Dealing with frame cancellation for stereoscopic displays in 3D user interfaces (2015)

This paper aims at reducing the ocular discomfort created by stereoscopy due to the effect called “frame cancellation”, for movies and interactive applications. This effect appears when a virtual object in negative parallax (front of the screen) is clipped by the screen edges; stereopsis cue lets observers perceive the object popping-out from the screen while occlusion cue provides observers with an opposite signal. Such a situation is not possible in the real world. This explains some visual discomfort for observers and leads to a poor depth perception of the scene. This issue is directly linked to the physical limitations of the display size that may not cover the entire field of view of the observer. To deal with these physical constraints we introduce two new methods in the context of interactive applications. The first method consists in two new rendering effects based on progressive transparency that aim to preserve the popping-out effect of the stereo. The second method focuses on adapting the interaction of the user, not allowing him to place virtual objects in an area subject to frame cancellation. Both methods have been evaluated and have shown a good efficiency in comparison to the state of the art approaches.
Chinese Medicine and Cancer Treatment in Hong Kong: A General Review (2007)

Cancer is a pathological condition. Removal of the cancer is a necessity in the treatment process. However, removal has reached its limitations as the cancer could, in the first place, be too extensive, or, in spite of the removal, recurrence still occurs. When the pathological process is not stopped, no matter how effective is the cancer removal, the formation of cancer is going to be repeated. Cancer treatment has therefore gone beyond the stage of cancer removal and other approaches such as controlling the blood supply, initiating apoptosis, and regulating the responsible genes, are considered important. The treatment approach needs to be modified from a single target, eliminative direction towards a multiple target, holistic direction. Chinese medicine lacks a perfect understanding of the causative pathology, hence it follows a multi-tar get holistic approach. As new systems of cancer treatment are not yet mature, using Chinese medicine as an adjuvant therapy could be an innovative and practical investment, to bring about better results of cancer control.

Intelligent Control for Haptic Displays (1996)

Abstract Usually, a mouse is used for input activities only, whereas output from the computer is sent via the monitor and one or two loudspeakers. But why not use the mouse for output, too? For instance, if it would be possible to predict the next interaction object the user wants to click on, a mouse with a mechanical brake could stop the cursor movement at the desired position. This kind of aid is especially attractive for small targets like resize handles of windows or small buttons. In this paper, we present an approach for the integration of haptic feedback in everyday graphical user interfaces. We use a specialized mouse which, is able to apply simple haptic information, to the user's hand and index finger. A multi‐agent system has been designed which ‘observes’ the ‘user in order to predict the next interaction object and launch haptic feedback, thus supporting positioning actions with the mouse. Although primarily designed in order to provide intelligent’ haptic feedback, the system can be combined with other output modalities as well, due to its modular and flexible architecture.
High dynamic range video with ghost removal (2010)

We propose a new method for ghost-free high dynamic range (HDR) video taken with a camera that captures alternating short and long exposures. These exposures may be combined using traditional HDR techniques, however motion in a dynamic scene will lead to ghosting artifacts. Due to occlusions and fast moving objects, a gradient-based optical flow motion compensation method will fail to eliminate all ghosting. As such, we perform simpler block-based motion estimation and refine the motion vectors in saturated regions using color similarity in the adjacent frames. The block-based search allows motion to be calculated directly between adjacent frames over a larger search range, yet at the cost of decreased motion fidelity. To address this, we investigate a new method to fix registration errors and block artifacts using a cross-bilateral filter to preserve the edges and structure of the original frame while retaining the HDR color information. Results show promising dynamic range expansion for videos with fast local motion.
Optical Scale Polarimetric Device for Nanotube Forest Measurement: An Opportunity to Anticipate Bistatic Polarimetric SAR Images of Tree Trunk Forests at P-Band (2016)

This paper investigates a new polarimetric device that produces reduced scale measurements for bistatic radar. The optical scale device is proposed to overcome the lack of real bistatic and full polarimetric radar acquisitions for forest of trunks. It is based on the scale invariant rule that is deduced from the Maxwell equations. From this principle, the electromagnetic (EM) response is kept at the reduced scale if the illumination wavelength is scaled and if the permittivity remains the same. This last condition needs the use of a carefully chosen material at optical scale. Nanoscale scenes are composed of carbon nanotubes (CNTs). They present several advantages: their arrangement is similar to the structure of a forest of trunks, their shape, and density can be controlled, it is possible to create very large scenes composed of thousands of elements, and finally their permittivity at optical wavelength is about the same order of magnitude than the permittivity of the tree trunks at radar wavelength. They are measured under the view of a microscope objective with a 633-nm wavelength laser playing the role of the EM source. The device images at once the forest polarimetric response, for a given transmitter location, and for the entire set of angular positions of reception. Two samples of forests with different densities are measured. They are analyzed using the Cloude and Pottier decomposition and the Lu and Chipman decomposition. The produced results are unprecedented on forest-like environment and it would be very helpful for the radar community.
Low‐resolution face recognition in uses of multiple‐size discrete cosine transforms and selective Gaussian mixture models (2014)

Owing to losing the detailed information, the low‐resolution problem in face recognition degrades the recognition performance dramatically. To overcome this problem, a novel face‐recognition system has been proposed, consisting of the extracted feature vectors from the multiple‐size discrete cosine transforms (mDCTs) and the recognition mechanism with selective Gaussian mixture models (sGMMs). The mDCT could extract enough visual features from low‐resolution face images while the sGMM could exclude unreliable observation features in recognition phase. Thus, the mDCT and the sGMM can greatly improve recognition rate at low‐resolution conditions. Experiments are carried out on George Tech and AR facial databases in 16 × 16 and 12 × 12 pixels resolution. The results show that the proposed system achieves better performance than the existing methods for low‐resolution face recognition.
Delivery of radiofrequency energy to the lower oesophageal sphincter and gastric cardia inhibits transient lower oesophageal sphincter relaxations and gastro-oesophageal reflux in patients with reflux disease (2003)

RFe has significant effects on LOS function that are associated with improvement in the antireflux barrier. Uncontrolled clinical data also suggest a beneficial effect in the control of reflux symptoms in these patients.
The role of subendothelial laminin and platelet laminin receptors in haemostasis. (1992)

Laminin (LM) is a basement membrane glyco-protein which exhibits a number of biological activities, including the promotion of cell attachment and migration. In a static system, platelets attach to LM without spreading. In order to elucidate the mechanisms mediating platelet-LM interactions under flow conditions, we studied the effects of blocking subendothelial LM and its platelet receptor. We measured the extent of platelet adhesion to the endothelial cell extracellular matrix (ECM) using a parallel plate perfusion chamber. To do this, we performed the following experiments: i) blockade of subendothelial LM by incubation of ECM with an anti-LM antibody (Ab); ii) blockade of the platelet receptor for LM with: a) an anti-67 KDa receptor Ab; and b) three different LM-derived peptides (CFALRGDNP, IKVAV and CDPGYIGSR). In i) perfusates consisted of whole blood, whereas in ii) perfusates were prepared with washed platelets pre-incubated with Ab or peptides and reconstituted with plasma and washed red blood cells. Perfusions were carried out at 800 s-1 shear rate. Platelet deposition was morphometrically evaluated by a computerized system. Our results indicated that when ECM was pre-incubated with an anti-LM Ab (100 micrograms/ml, 30 min, 37 degrees C) a reduction of the surface coverage (SC) of 23.3 +/- 2.3% (p less than 0.01) was observed. When washed platelets were pre-incubated with an anti-67 KDa receptor Ab (40 micrograms/ml, 30 min, 37 degrees C) their interaction with ECM was decreased by 22.3 +/- 2.1% of SC (p less than 0.005). In other experiments platelets were pre-incubated with CFALRGDNP, IKVAV and CDPGYIGSR (200 micrograms/ml, 30 min, 37 degrees C).(ABSTRACT TRUNCATED AT 250 WORDS)
Design of an arrayed waveguide grating with flat spectral response (2002)

Arrayed Waveguide Gratings (AWGs) are key components in current and future optical network realizations. In order to prevent the need of accurate wavelength control the transfer function of the AWG should ideally have a rectangular shape. Several techniques have been proposed in order to flatten the Gaussian-like transfer function of the conventional AWG. In this paper we propose a new technique is based on the modification of the arrayed waveguide lengths and their positions on the Free Propagation Regions. The above technique is similar to the deterministic tapering technique used in the design of antenna arrays, since the spatial transfer function of the latter has the same characteristics as the spectral transfer function of an AWG. Therefore, problem is reduced to that of matching the integral of a sinc function with a discrete step function and the optimal waveguide lengths are obtained by solving a set of equations numerically. The performance of this technique (in terms of transfer function flatness, sidelobe level and insertion losses compared to a conventional AWG) depends on the values given to several initial design parameters related to the AWG geometry. The results obtained show that it is feasible to fabricate AWGs with rectangular transfer function with proper adjustment of certain structural parameters.
Computational Fluid Dynamic simulation of the supersonic CO2 expansion during champagne cork popping (2022)

Abstract Behind the iconic “pop!" accompanying the uncorking of a champagne bottle hides a gas flow of surprising complexity. Its modeling is made delicate by its supersonic nature, its interaction with the cork stopper, the eminently unsteady character of the flow escaping from the bottle, and the continuous change of the geometry of the computational flow domain due to the displacement of the cork. Our numerical simulations reveal the formation, evolution and dissipation of shock wave patterns during the first millisecond following cork popping. A first crown-shaped shock wave pattern develops radially, then followed by the formation of a detached shock wave, or bow shock, induced by the presence of the cork in the axial path of the supersonic gas. The numerical simulations correctly reproduce the position of the bow shock previously observed through high-speed imaging.

According to the actual demand of hotel chain industry for improving guests' living environment, the paper also discusses the design of IOT application scheme with using the IOT gateway as a bridge. The scheme may effectively meet the service requirements of hotel chain industry.
Inhibition of MRSA and of Clostridium Difficile by Durancin 61A: Synergy with Bacteriocins and Antibiotics (2017)

Durancin and reuterin were effective inhibitors of Clostridium difficile, vancomycin-resistant Enterococcus faecium and methicillin-resistant Staphylococcus aureus. The combination of durancin and reuterin was highly synergistic against C. difficile (fractional inhibitory concentration index = 0.2). Durancin/vancomycin combination was synergistic against S. aureus ATCC<sup>®</sup> 700699 (fractional inhibitory concentration index = 0.3). Conclusion & future perspective: Durancin 61A alone or combined with other bacteriocins or antibiotics may therefore provide a possible therapeutic option for the treatment of infections by these pathogens.
Recycling Waste Polymers in EAF Steelmaking: Influence of Polymer Composition on Carbon/Slag Interactions (2012)

Interactions between blends of metallurgical coke and polymers with EAF slag (30.5% FeO) at 1550°C have been investigated using a sessile drop arrangement to determine the influence the polymer and its chemical composition on carbon/slag interactions. Two polymers, namely polyethylene terephthalate (PET) and polyurethane (PU), were used in this study. The CO emissions during carbon/slag interactions for PET/Coke and PU/Coke blends were lower as compared to corresponding emissions from metallurgical coke. An improvement in slag foaming, as determined by the dynamic changes in the volume of the slag droplet, was observed when PET/Coke and PU/Coke blends were used compared to the coke alone. Relatively greater number of gas bubbles was found to be entrapped in the slag droplet along with reduced iron droplets. Higher level of H2O formation was also seen in the case of PET/Coke and PU/Coke blends as a result of FeO reduction by H2. These results indicate that volatiles (H2 and CH4) released from the polymer/coke blends can influence the interactions between carbon and slag (in addition to reduction reactions by solid carbon). This study shows that a variety of waste polymers can be utilised as a carbon resource in EAF steelmaking processes.
