Numerical study of shock-wave/boundary-layer interactions in premixed combustible gases (1992)

A computational study of shock-wave/boundary-layer interactions involving premixed combustible gases is presented. The analysis is carried out using a new fully implicit, total variation diminishing code that solves the fully coupled Reynolds-averaged Navier-Stokes equations and species continuity equations in an efficient manner. To accelerate the convergence of the basic iterative procedure, the code is combined with vector extrapolation methods. The chemical nonequilibrium processes are stimulated by means of a finite-rate chemistry model for hydrogen-air combustion

In recent times, data is growing rapidly in every domain such as news, social media, banking, education, etc. Due to the excessiveness of data, there is a need of automatic summarizer which will be capable to summarize the data especially textual data in original document without losing any critical purposes. Text summarization is emerged as an important research area in recent past. In this regard, review of existing work on text summarization process is useful for carrying out further research. In this paper, recent literature on automatic keyword extraction and text summarization are presented since text summarization process is highly depend on keyword extraction. This literature includes the discussion about different methodology used for keyword extraction and text summarization. It also discusses about different databases used for text summarization in several domains along with evaluation matrices. Finally, it discusses briefly about issues and research challenges faced by researchers along with future direction.
An immediate (type I) hypersensitivity reaction during placement of a dental rubber dam. (1997)

A dental student developed swelling of the lips and peri-oral urticaria, immediately after placement of a dental rubber dam during a chairside demonstration of clinical dentistry. A provisional diagnosis of a Type I hypersensitivity reaction to natural rubber latex was made and an appointment organised for specialist investigations. The student reported an atopic history and allergy to peanuts. A Radioallergosorbent Test (RAST), to measure Ig-E antibodies to latex, was positive. The dental student was given advice concerning the avoidance of natural rubber latex. Dental staff must be aware of potentially serious reactions to natural rubber latex in the dental surgery.
Transmission comb of a distributed Bragg reflector with two surface dielectric gratings (2016)

The transmission behaviour of a distributed Bragg reector (DBR) with surface dielectric gratings on top and bottom is studied. The transmission shows a comb-like spectrum in the DBR band gap, which is explained in the Fano picture. The number density of the transmission peaks increases with increasing number of cells of the DBR, while the ratio of the average full width at half maximum to the corresponding average free spectral range, being only few percent for both transversal electric and magnetic waves, is almost invariant. The transmission peaks can be narrower than 0.1 nm and are fully separated from each other in certain wavebands. We further prove that the transmission combs are robust against randomness in the heights of the DBR layers. Therefore, the proposed structure is a candidate for an ultra-narrow-band multichannel filter or polarizer.
Mobile, hardware-accelerated urban 3D maps in 3G networks (2007)

3D maps can visualize static and dynamic features of real environments, and act as 3D gateways to location-based information. Insufficient network speed has been a major bottleneck for dynamic download of 3D content for mobile devices. 3G network technologies promise to solve this issue, allowing faster response times and higher data rates. Similarly, mobile 3D graphics hardware should provide a dramatic increase in rendering speed. We examine wireless IP network properties, and develop an optimized network scheme suited for navigation purposes. The presented system allows free roaming in the 3D scene, while progressively down-loading 3D data. For case platforms, we use two 3G Symbian smart phones, one with 3D hardware and one without. Network, 3D rendering and overall application performances are measured. For a scalable 3D engine, 3D hardware improves the rendering performance by over an order of magnitude. By using a compressed network protocol and efficiently formatted 3D data, a textured but lightweight 3D city can be progressively downloaded in 3G networks fast and without degrading application responsiveness.
Web based Targeted Advertising: A Study based on Patent Information (2014)

Over the past two decades, rapid developments in the field of information and communication technologies (ICT) have resulted in an increased reach and use of internet by the general public. Building on these advances, a rapid development of e-commerce has taken place which has resulted in the emergence of Internet as an important medium for advertising. Through a variety of technological advances, the Internet has allowed advertisers to address a targeted audience which in general was beyond the reach of traditional media. The Internet thus offers opportunities for advertisers to present advertisements to a captive audience based on various criteria. Intellectual Property Rights (IPR) on the other hand, help protect technologies via various means. The advancements made in field of information technology coupled with business methods can be protected by patents. Patent rights prevent others from practicing (making, using or selling) a claimed invention in a particular territory for a limited time during the life of the patent. Patents often are the first and many a times, the only source in which technology is revealed. Thus patents can act as important techno-legal documents, containing various different kinds of information related to technology and/or its advancements. In the present study, patents are used as source of information to understand how advancements in ICTs has influenced business and more particularly how the ICT is being used for internet based targeted advertising.
Isolation and sequencing of the cDNA encoding the 75-kD human sperm protein related to infertility. (1992)

Serum was obtained from an infertile woman (IS) inducing head-to-head agglutination of human sperm and was used to screen a human testis lambda gt11 cDNA library. A plaque producing the interacting antigen was located. The recombinant lambda gt11 was isolated and cut with EcoRI releasing a 0.7-kb cDNA. Using the 0.7-kb cDNA as a probe, a larger cDNA of 2.4 kb was isolated and its nucleotide sequence determined. It was composed of 2 427 nucleotides with an open reading frame of 1584 nucleotides encoding 528 amino acid residues. The specific antisperm antibody was isolated from IS by epitope selection, using positive plaques of E. coli Y1090. The epitope-selected antibodies interacted with a 75-kD human sperm protein and with a polypeptide in the form of a beta-galactosidase fusion protein in the recombinant lysate of E. coli Y1089, determined by immunoblot. The fusion protein was purified by affinity chromatography on an anti-beta-galactosidase-Sepharose column. It is proposed that production of anti-75-kD antibodies may be the underlying cause of the infertility.
On the Exploration of Information From the DTW Cost Matrix for Online Signature Verification (2017)

This paper explores the utility of information derived from the dynamic time warping (DTW) cost matrix for the problem of online signature verification. The prior works in literature primarily utilize only the DTW scores to authenticate a test signature. To the best of our knowledge, the characteristics of the warping path (used for the alignment) in the cost matrix is hardly exploited for verification of online signatures. Accordingly, we devise a score that utilizes the information from the cost matrix and warping path alignments. We subsequently consider its fusion (using a sum rule combiner) with the DTW score for authenticating the veracity of a test signature. In addition, a minor modification is suggested with regards to the set of features employed for matching the signatures. We introduce a spacing parameter for feature extraction and demonstrate its applicability in increasing the separation between the distribution of genuine and forgery signatures for an user. Our method has been tested on two publicly available online signature databases namely the SVC-2004 Task 2 and MCYT-100. We report reduction in error rates over the traditional DTW framework.
The potential scale of aeolian structures on Venus (1991)

Simulations of the Venusian aeolian environment with the Venus Wind Tunnel have shown that microdunes are formed during the entrainment of sand-sized material. These structures are several tens of centimeters long (2-3 cm high) and combine the morphological and behavioral characteristics of both full-scale terrestrial dunes and current ripples formed in subaqueous environments. Their similarity to both reflects the fact that the Venusian atmosphere has a density intermediate between air and water. Although the development of microdunes in the wind tunnel experiments was limited by tunnel dimensions, it is possible to make some predictions about their potential size on Venus, and the potential size of related aeolian structures. Microdunes are fluid-filled structures (as are dunes and current ripples) and as such have no theoretical upper limit to their size from a fluid dynamics viewpoint. Limitations to size observed in subaqueous structures are set by, for example, water depth; limitations to the size of dunes are set by, for example, sand supply. It is therefore reasonable to suppose that the microdunes on Venus could evolve into much larger features than those observed in experiments. In addition, the researchers note that current ripples (which are closely related to microdunes) are often found in association with giant ripples that have dimensions similar to aeolian dunes. Thus, it may be reasonable to assume that analogous large scale structures occur on Venus. Both (terrestrial) aeolian and subaqueous environments generate structures in excess of one hundred meters in wavelength. Such dimensions may therefore be applicable to Venusian bedforms. Analysis of Magellan data may resolve the issue.
Investigations of Nd:YAG laser formed connections and disconnections of standard CMOS double level metallizations (2002)

Nd:YAG laser processing of vertical links and cutting of interconnections in both metallization levels have been investigated. Main emphasis was on examination of the statistics of laser processing and the reliability of the processed antifuses. For this purpose, a special test chip has been designed and fabricated in a standard double level CMOS process. Laser cutting of interconnections is possible with one pulse in both metallization levels without passivation opening. For laser linking with the pulsed Nd:YAG, simply expanded interconnections turned out to be best suitable. Structures which are passivated prior to laser processing showed a significantly higher yield than depassivated combined with improved reproducibility of laser processing. Best yield of 99.4% with contact resistances <0.3 Omega has been achieved with expansions of 20*20 mu m/sup 2/. However, expansions of 14*14 mu m/sup 2/ are the best choice as yield is only slightly below that of the larger structures and consumption of area is much less. Accelerated life time tests with current densities up to 1*10/sup 6/ A/cm/sup 2/ and temperatures up to 270 degrees C were carried out. Materials were analysed with EDX, AES, and SIMS.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
On the resolution of the isotropic component in moment tensor inversion (1997)

It is in theory possible to solve a full moment tensor from inversion of a few seismograms, using normal-mode data, surface waves or body waves. In fact, the isotropic component is usually set to zero in many inversions, in order to stabilize them. This approximation may be considered valid for tectonic earthquakes, but for other applications (such as the study of nuclear or volcanic explosions, deep earthquakes and induced seismicity), the determination of the volumetric component is a key point of the inversion. Our aim is to investigate under which practical conditions the determination of the isotropic component is feasible, and is mathematically and physically reliable. In the first part, we examine the question from a physical point of view and show that the classical interpretation of a full moment tensor for tectonic events implies rheological constraints that are not always realistic. We therefore propose an extended physical model which includes tectonic and non-tectonic volumetric variations. In the second part, we use the tools of inverse theory to infer mathematical constraints on the problem of full moment tensor inversions, from teleseimic surfacewave or body-wave spectra. In particular, we examine how much of the moment tensor can be solved, in relation to the eigenvalues, the condition number and the sampling of the inverse problem. In addition, the resolution and the correlation matrices show that, among a choice of possible constraints on the full tensor, a constraint on the isotropic component is most valuable. In the third part, we also show some applications of our theoretical developments to regional waveform inversions, using the 1992 April Roermond, the Netherlands, earthquake. In addition to physically reliable estimations of the tectonic and non-tectonic isotropic components in full moment tensor inversions, we finally propose extensions of the basic linear methods that can lead to particular models in subspaces of interest, such as tectonic models, or decompositions in a doublecouple plus a volumetric part. By revisiting carefully the determination and interpretation of moment tensors, we provide new perspectives in the estimation of the model and of its error, for a more flexible tectonic and physical interpretation of source mechanisms.
Genetic Susceptibility of Mice to <i>Candida albicans</i> Vaginitis Correlates with Host Estrogen Sensitivity (2004)

We compared susceptibility to Candida vaginitis in derived murine substrains differing in sensitivity to estrogen (CD-1 and CD10, resistant; CD3 and C57BL/6 responsive), and in F1 crosses. The order of decreasing resistance was CD-1 > or = CD10 > or = CD10 x CD3F1 > CD10 x B6F1 > CD3 > C57BL/6 and correlated with estrogen responsiveness in endocrine disruptor assays. Resistance to Candida vaginitis appears additive in CD10 x B6F1 animals and dominant in CD10 x CD3F1 animals.
Low-dose <i>N</i> -Acetylcysteine Protects Rats against Endotoxin-mediated Oxidative Stress, But High-dose Increases Mortality (1998)

We evaluated the effect of the antioxidant N-acetylcysteine (NAC) on oxidative stress, lung damage, and mortality induced by an endotoxin (lipopolysaccharide, or LPS) in the rat. Continuous intravenous infusion of 275 mg NAC/kg in 48 h, starting 24 h before LPS challenge, decreased hydrogen peroxide (H2O2) concentrations in whole blood (p < 0.01). This decrease was accompanied by fewer histologic abnormalities of the lung and decreased mortality (p < 0.025), compared with rats receiving LPS alone. N-Acetylserine, which has no sulfhydryl group, did not protect rats against LPS toxicity. Improved survival was not associated with an increase in pulmonary reduced glutathione, nor with inhibition of serum tumor necrosis factor (TNF) activity. In vitro, TNF production and DNA binding of nuclear factor kappa B (NF-kappaB) in human Mono Mac 6 cells was only inhibited at concentrations of NAC above 20 mM. High-dose NAC treatment (550 and 950 mg/kg in 48 h) decreased lung GSH (p < 0.05) and resulted in a significantly smaller number of surviving animals when compared with the low-dose NAC group (p < 0.025). In vitro, NAC increased hydroxyl radical generation in a system with Fe(III)-citrate and H2O2 by reducing ferric iron to its catalytic, active Fe2+ form. We conclude that low-dose NAC protects against LPS toxicity by scavenging H2O2, while higher doses may have the opposite effect.
Security and privacy in a middleware for large scale mobile and pervasive augmented reality (2007)

Ubiquitous or pervasive computing is a new kind of computing, where specialized elements of hardware and software will have such high level of deployment that their use will be fully integrated with the environment. Augmented reality extends reality with virtual elements but tries to place the computer in a relatively unobtrusive, assistive role. In this paper we propose, test and analyse a security and privacy architecture for a previously proposed middleware architecture for mobile and pervasive large scale augmented reality games, which is the main contribution of this paper. The results show that the security features proposed in the scope of this work do not affect the overall performance of the system.

Two- versus three-dimensional imaging in subjects with unerupted maxillary canines (2010)

The aim of this study was to evaluate whether there is any difference in the diagnostic information provided by conventional two-dimensional (2D) images or by three-dimensional (3D) cone beam computed tomography (CBCT) in subjects with unerupted maxillary canines. Twenty-seven patients (17 females and 10 males, mean age 11.8 years) undergoing orthodontic treatment with 39 impacted or retained maxillary canines were included. For each canine, two different digital image sets were obtained: (1) A 2D image set including a panoramic radiograph, a lateral cephalogram, and the available periapical radiographs with different projections and (2) A 3D image set obtained with CBCT. Both sets of images were submitted, in a single-blind randomized order, to eight dentists. A questionnaire was used to assess the position of the canine, the presence of root resorption, the difficulty of the case, treatment choice options, and the quality of the images. Data analysis was performed using the McNemar-Bowker test for paired data, Kappa statistics, and paired t-tests. The findings demonstrated a difference in the localization of the impacted canines between the two techniques, which can be explained by factors affecting the conventional 2D radiographs such as distortion, magnification, and superimposition of anatomical structures situated in different planes of space. The increased precision in the localization of the canines and the improved estimation of the space conditions in the arch obtained with CBCT resulted in a difference in diagnosis and treatment planning towards a more clinically orientated approach.
Geometrical compensation for multi-view video in multiple camera array (2008)

In this paper, we present a geometrical compensation method for a calibrated multi-view video that is captured by the one-dimensional (1-D) parallel or arc camera array. Since the multi-view video may include geometical errors, we define a compensating transformation based on a two-dimensional (2-D) homography. After we apply the compensating transformation, we obtain all the image planes which are aligned vertically and rotated to be suitable for the camera array. Experimental results show that the proposed method correctly compensates the geometrical errors of the multi-view video. We can provide not only a clear viewpoint change in the multi-view video but also the simplicity and accuracy in matching between adjacent views.
Wearable textile antenna in substrate integrated waveguide technology (2012)

A novel wearable substrate integrated waveguide antenna fabricated entirely from textile materials is presented. The cavity-backed slot antenna operates in the 2.45 GHz industrial, scientific and medical band, for short range communication between rescue workers. A prototype of the antenna was fabricated and tested: good performance was obtained in terms of input matching and radiation pattern. Moreover, measurements performed on the antenna after bending and integration into clothing indicate high robustness against deformation and low influence of the human body on antenna performance, making the design well-suited for on-body use.
Regulation of the immune system by synthetic polynucleotides. I. Characteristics of adjuvant action on antibody synthesis. (1971)

Equimolar complexes of the synthetic polyribonucleotides, polyadenylic and polyuridylic acid (poly(A:U)), or polyinosinic and polycytidylic acid (poly(I:C)) were shown to be adjuvants for antibody formation in mice. A decreased induction period and increases in 19S and 7S antibody titers and in immunologic memory were noted. Poly(A:U) increased the antibody response to a variety of antigens including both soluble and particulate proteins, sheep red blood cells, and a polysaccharide, the Vi antigen of Escherichia coli . In addition, antibody formation to bovine γ globulin was enhanced in mice, rabbits and guinea pigs. Antigenicity was increased considerably in that poly(A:U) was capable of rendering 1 ng of bovine γ globulin immunogenic. When injected 0.5 to 1 day before antigen, poly(A:U) was found to be immunosuppressive. However, a second injection of poly(A:U) given with antigen abolished the immunosuppression induced by the first dose of poly(A:U). Study of various physical and chemical factors necessary for the adjuvant action of poly(A:U) revealed that no polynucleotide alone acted as an adjuvant nor were other known interferon-inducing polymers effective. Complexes composed of altered molar proportions were no more effective than an equimolar complex, and neither purine nor pyrimidine mono- and oligonucleotides could replace their respective polynucleotides in the poly(A:U) complex. Decreasing the hydrogen bonding in the complex through use of chemically modified poly A and poly U caused a reduction in the adjuvant action. In addition, neither repeated freeze-thawing nor prolonged incubation at room temperature minimized the adjuvant action of poly (A:U). Heat denaturation rendered the complex ineffective, as did treatment with ribonuclease or incubation in normal mouse serum.
