An M-band differentially fed, aperture coupled stacked patch antenna in LTCC (2008)

A novel antenna design for an M-band UWB antenna to be realized in LTCC technology is presented. The antenna concept is based on slot-fed stacked patches, while antenna feeding is done differentially via two pins. LTCC technology provides extra constrains on the antenna design. Based on simulation the proposed antenna has an operational bandwidth between 55.4 GHz to 68.2 GHz with a gain of around 4 to 5 dBi and a front-to-back ratio of 12.2 dB.
Click to Zoom-Inside Graphical Authentication (2009)

We propose and evaluate the usability and security of Click to Zoom-inside (CTZ); a new graphical password authentication mechanism. Users have to click six times on one point in some given specific regions (pass regions) shown with dotted lines in a theme image displayed on the screen. The selected region is then zoom to create a next image. Exactly, we are not going to zoom the region object of the theme image up to six times; rather we are replacing the image with another image of the same object in big size. The next image is based on the previous click-region. We secure our scheme from shoulder surfer attacking by using WIW scheme with our scheme. We also present the results of an initial user study which revealed positive results. Performance was very good in terms of speed, accuracy, and number of errors in recognizing the images. We can also demonstrate that CTZ provides greater security than Pass Points because the number of images increases the workload for attackers also it is more user friendly and attractive than other competitive schemes. It is just parallel to Cued Click Scheme. It meets the todaypsilas requirement of extremely high security.
Hyperspectral remote sensing to detect leafminer‐induced stress in bok choy and spinach according to fertilizer regime and timing (2020)

We conclude that detailed hyperspectral profiles (not single spectral bands) can accurately detect and diagnose leafminer infestation over time and across fertilizer regimes. Hyperspectral remote sensing data acquisition at night with an active light source has the potential to enable arthropod infestations in glasshouse-grown crops, such as, bok choy and spinach. In addition, we conclude that effective use and deployment of hyperspectral remote sensing requires thorough performance assessments of classification algorithms, and we propose an analytical performance method to address this important matter. © 2020 The Authors.

Nonwovens as Three-Dimensional Textiles for Composites (1995)

Abstract Three-dimensional textiles are those materials which have a system or systems in all the three axes of plane. These offer particular properties, such as interlaminar shearing force, and mechanical and thermal stability along all three axes of space, which are not achievable with other reinforcements. The demand for these types of fabrics is expected to increase, especially in the areas of high performance composites in automobile industry, housing, construction and reinforcement materials. Reduction in manufacturing and raw materials costs has to be brought about in order to make the advanced composites competitive in the current market and acceptable in the future new markets. Nonwovens, which are a major constituent of this class of textiles are becoming important because of their ease of manufacture and low production cost. This is a comprehensive review of different methods of manufacturing 3-D textiles with an emphasis on nonwovens.
SUPERCONDUCTIVITY IN <font>Tl-Ca-Ba-Cu-O</font> COMPOUNDS (1988)

We report the constitution, characterization and superconducting temperatures of the novel high-T c superconductor Tl-Ca-Ba-Cu-O. For the nominal composition of Tl 2 Ba 2 Ca 2 Cu 3 O 10 , T c onset up to 130K (midpoint: 120K, zero resistivity: 118.5K) have been found.
Evidence that the Root of the Tree of Life Is Not within the Archaea (2006)

The Archaea occupy uncommon and extreme habitats around the world. They manufacture unusual compounds, utilize novel metabolic pathways, and contain many unique genes. Many suspect, due to their novel properties, that the root of the tree of life may be within the Archaea, although there is little direct evidence for this root. Here, using gene insertions and deletions found within protein synthesis factors present in all prokaryotes and eukaryotes, we present statistically significant evidence that the root of life is outside the Archaea.
Sorption Phenomena Significant in Radioactive Waste Disposal: ABSTRACT (1971)

This DOI is not currently attached to any metadata records. DOIs can’t actually ever be deleted (they’re persistent), but sometimes our members create DOIs in error. We do have a process to approximate deletion which we follow only in rare cases where the DOI has been genuinely created in error, and most crucially, if the DOI has never been published anywhere online or in print and never otherwise distributed to or communicated with anyone (authors, readers, reviewers, etc.
An Emphasis on Small, Entrepreneurial Firms (2013)

The SBIR program is focused on small, entrepreneurial firms. Arguments supporting a policy emphasis on small, entrepreneurial firms are summarized in this chapter from a historical perspective.
Oxygen transfer involving nonheme iron: the influence of leaving group ability on the rate constant for oxygen transfer to (EDTA)Fe(III) from peroxycarboxylic acids and hydroperoxides. (1987)

Ethylenediaminetetraacetato iron(III) [(EDTA)Fe(III)] has been shown to react with a series of four peroxycarboxylic acids and four alkyl hydroperoxides (YOOH; dry methanol solvent, 30 degrees C) by heterolytic O-O bond scission that accompanies the transfer of an oxygen atom to the iron(III) moiety [(EDTA)Fe(III) + YOOH----[(EDTA)(FeO)]+ + YOH]. A single linear free-energy relationship exists for both peroxycarboxylic acids and alkyl hydroperoxides when the logarithm of the second-order rate constant (kYOOH) for reaction of YOOH species with (EDTA)Fe(III) is plotted vs. the pKa of the YOH leaving group.
Effects of White Blood Cells on the <i>In Vitro</i> Penetration of Zona‐free Hamster Eggs by Human Spermatozoa (1985)

The presence of white blood cells in semen has been associated with male infertility. Previous studies indicate that pyospermia occurs in conjunction with decreases in sperm motility, number of normal sperm forms, and penetration rates in the zona-free hamster egg sperm penetration assay. We have evaluated the relationship of seminal white blood cells and sperm function, as reflected in the zona-free hamster egg penetration assay, and have investigated the possible mode of action of the white cells. Egg penetration rates decreased when white blood cells from fertile or potentially fertile donors were added to their sperm suspensions prior to preincubation and at insemination in the in vitro assay. Zona-free hamster egg penetration assay results were also inhibited when the supernatant from white blood cells incubated in Biggers, Whitten, and Whittingham (BWW) medium overnight were introduced to sperm-oocyte suspensions at insemination. Conversely, egg penetration rates were enhanced in samples from hypofertile individuals when white blood cell concentrations in the semen or WBC/sperm ratios were reduced, either by physical removal or as a result of antibiotic therapy. The physical presence of leukocytes, and possibly, the extracellular release of lysosomal enzymes may be responsible for the inhibitory effects in vitro. Although the mechanism(s) by which white blood cells interfere with the fertilizing capacity of spermatozoa are not clear, it is quite obvious that their presence in the in vitro environment is undesirable and can mask an individual's actual fertilizing potential.
Vertex-Linked ZnO<sub>2</sub>S<sub>2</sub> Tetrahedra in the Oxysulfide BaZnOS:  a New Coordination Environment for Zinc in a Condensed Solid (2005)

The wide-band-gap semiconductor BaZnOS adopts a high-symmetry modification of the SrZnO2 structure type and contains layers of vertex-linked ZnO2S2 tetrahedra, which represent a novel coordination environment for zinc in the solid state. BaZnOS: orthorhombic, space group Cmcm; a = 3.9619(2) angstroms, b = 12.8541(7) angstroms, c = 6.1175(4) angstroms, Z = 4. Diffuse-reflectance spectroscopy measurements reveal a direct band gap of 3.9(3) eV, consistent with the white color and the results of band structure calculations. The band gap is larger than those observed in ZnO and ZnS, consistent with the more ionic nature of BaZnOS. Attempts to dope this compound electronically have so far not proved possible.
Transcription regulation of peroxisomal fatty acyl-CoA oxidase and enoyl-CoA hydratase/3-hydroxyacyl-CoA dehydrogenase in rat liver by peroxisome proliferators. (1986)

The structurally diverse peroxisome proliferators ciprofibrate, clofibrate, and bis(2-ethylhexyl) phthalate [(EtHx)2 greater than Pht] increase the activities of hepatic catalase and peroxisomal fatty acid beta-oxidation enzymes in conjunction with profound proliferation of peroxisomes in hepatocytes. In order to delineate the level at which these enzymes are induced in the liver, the transcriptional activity of specific genes for fatty acyl-CoA oxidase (FAOxase) and enoyl-CoA hydratase/3-hydroxyacyl-CoA dehydrogenase bifunctional enzyme (PBE), the first two enzymes of the peroxisomal beta-oxidation system, and for catalase were measured in isolated hepatocyte nuclei obtained from male rats following a single intragastric dose of ciprofibrate, clofibrate, or (EtHx)2 greater than Pht. All three peroxisome proliferators rapidly increased the rate of FAOxase and PBE gene transcription in liver, with near maximal rates (9-15 times control) reached by 1 hr and persisting until at least 16 hr after administration of the compound. FAOxase and PBE mRNA levels, measured by blot-hybridization analysis and FAOxase and PBE protein content, analyzed by immunoblotting, increased concurrently up to at least 16 hr following a single dose of peroxisome proliferator. The catalase mRNA level increased about 1.4-fold, but the transcription rate of the catalase gene was not significantly affected. The results show that the peroxisome proliferators clofibrate, ciprofibrate, and (EtHx)2 greater than Pht selectively increase the rate of transcription of peroxisomal fatty acid beta-oxidation enzyme genes. Whether the transcriptional effects are mediated by peroxisome proliferator-receptor complexes remains to be elucidated.
Extreme critical-temperature enhancement of Al by tunneling in Nb/<mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" display="inline"><mml:mrow><mml:msub><mml:mrow><mml:mi mathvariant="normal">AlO</mml:mi></mml:mrow><mml:mrow><mml:mi mathvariant="italic">x</mml:mi></mml:mrow></mml:msub></mml:mrow></mml:math>/Al/<mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" display="inline"><mml:mrow><mml:msub><mml:mrow><mml:mi mathvariant="normal">AlO</mml:mi></mml:mrow><mml:mrow><mml:mi mathvariant="italic">x</mml:mi></mml:mrow></mml:msub></mml:mrow></mml:math>/Nb tunnel junctions (1991)

High-conductance Nb/${\mathrm{AlO}}_{\mathit{x}}$/Al/${\mathrm{AlO}}_{\mathit{x}}$/Nb tunnel-junction devices with the Al thickness varying from 3 to 20 nm have been fabricated using a whole-wafer processing route. Current-voltage measurements show a step in the subgap structure corresponding to the difference in the energy gaps V=2(${\mathrm{\ensuremath{\Delta}}}_{\mathrm{Nb}}$-${\mathrm{\ensuremath{\Delta}}}_{\mathrm{Al}}$) of the two superconductors. The measured ${\mathrm{\ensuremath{\Delta}}}_{\mathrm{Al}}$ is large and persists to temperatures considerably in excess of the equilibrium critical temperature of the Al. This is interpreted as arising from a tunnel-induced gap enhancement which is an order of magnitude larger than has been seen previously.
Design and Structural Analysis of Aromatic Inhibitors of Type II Dehydroquinase from <i>Mycobacterium tuberculosis</i> (2014)

3-Dehydroquinase, the third enzyme in the shikimate pathway, is a potential target for drugs against tuberculosis. Whilst a number of potent inhibitors of the Mycobacterium tuberculosis enzyme based on a 3-dehydroquinate core have been identified, they generally show little or no in vivo activity, and were synthetically complex to prepare. This report describes studies to develop tractable and drug-like aromatic analogues of the most potent inhibitors. A range of carbon-carbon linked biaryl analogues were prepared to investigate the effect of hydrogen bond acceptor and donor patterns on inhibition. These exhibited inhibitory activity in the high-micromolar range. The addition of flexible linkers in the compounds led to the identification of more potent 3-nitrobenzylgallate- and 5-aminoisophthalate-based analogues.
Unusual mobility of hypercrosslinked polystyrene networks: Swelling and dilatometric studies (2000)

Hypercrosslinked polystyrene samples were prepared by an intensive postcrosslinking of highly swollen styrene–divinylbenzene copolymer beads to extremely high degrees of crosslinking that amounted to 100% or even higher. When in the dry state, the materials obtained represent transparent beads of reduced density. Despite the high degree of crosslinking, the materials manifest large increases in volume on swelling with any liquid media as well as large changes in volume on heating. The factors determining the unusual swelling ability of the hypercrosslinked polymers are briefly discussed. Thermodilatometric tests of the polymers with a moderate degree of crosslinking reveal a certain contraction of the beads at temperatures higher than 100 °C. When crosslinked far beyond 100%, the networks demonstrate unusual expansion in the 100–220 °C range; this is followed by a sharp shrinking at higher temperatures. The former is caused by an increased intensity of the vibration movements of the network and a partial relaxation of strong inner stresses; the latter is due to partial chemical oxidation, degradation of network units, or both. This degradation, however, is not accompanied by any loss in weight of the polymer but only results in a transformation into a more dense conventional nonporous material. The strained, rigid open-work structure of the homogeneous expanded hypercrosslinked polystyrene networks is responsible for their unusual mobility. © 2000 John Wiley & Sons, Inc.

Extracting Data Region in Web Page by Removing Noise using DOM and Neural Network (2011)

Today, with the explosive growth of information sources available on the World Wide Web, it has become increasingly difficult to identify the relevant pieces of information because Web pages are often cluttered with distracting features around the body of an article that distract Web user from the actual content they are interested in. An important problem for information extraction from the web is the identification and removal of noise. In this paper, we investigate to extract informative content block from Web documents by removing noise blocks. So, to extract information from these pages, several challenges must be overcome. Another existing informative content extraction system implemented nowadays depends on rule-based systems where Web sites with various templates are not applicable. In our task, a possible application of Neural Networks is presented for three pattern classification combine with DOM structure to extract content information. The type of Neural Network used to implement our system is feed forward which uses the back propagation learning algorithm. The data used in training and testing is collected from several Web sites. The classification result of back propagation neural network is used for eliminating various noise patterns from Web page. In order to evaluate our proposed system, we perform the experiment on several Web pages of different News Web sites and Commercial Web sites as data set. Experiments indicate our method is applicable to extract informative content from Web pages of these Web sites.
Satellite image forgery detection and localization using GAN and One-Class classifier (2018)

Current satellite imaging technology enables shooting highresolution pictures of the ground. As any other kind of digital images, overhead pictures can also be easily forged. However, common image forensic techniques are often developed for consumer camera images, which strongly differ in their nature from satellite ones (e.g., compression schemes, post-processing, sensors, etc.). Therefore, many accurate state-of-the-art forensic algorithms are bound to fail if blindly applied to overhead image analysis. Development of novel forensic tools for satellite images is paramount to assess their authenticity and integrity. In this paper, we propose an algorithm for satellite image forgery detection and localization. Specifically, we consider the scenario in which pixels within a region of a satellite image are replaced to add or remove an object from the scene. Our algorithm works under the assumption that no forged images are available for training. Using a generative adversarial network (GAN), we learn a feature representation of pristine satellite images. A one-class support vector machine (SVM) is trained on these features to determine their distribution. Finally, image forgeries are detected as anomalies. The proposed algorithm is validated against different kinds of satellite images containing forgeries of different size and shape.
Dynamics of Wicking in Silicon Nanopillars Fabricated with Interference Lithography and Metal-Assisted Chemical Etching (2012)

The capillary rise of liquid on a surface, or "wicking", has potential applications in biological and industrial processes such as drug delivery, oil recovery, and integrated circuit chip cooling. This paper presents a theoretical study on the dynamics of wicking on silicon nanopillars based on a balance between the driving capillary forces and viscous dissipation forces. Our model predicts that the invasion of the liquid front follows a diffusion process and strongly depends on the structural geometry. The model is validated against experimental observations of wicking in silicon nanopillars with different heights synthesized by interference lithography and metal-assisted chemical etching techniques. Excellent agreement between theoretical and experimental results, from both our samples and data published in the literature, was achieved.
Conformational analysis of nucleic acids revisited: Curves+ (2009)

We describe Curves+, a new nucleic acid conformational analysis program which is applicable to a wide range of nucleic acid structures, including those with up to four strands and with either canonical or modified bases and backbones. The program is algorithmically simpler and computationally much faster than the earlier Curves approach, although it still provides both helical and backbone parameters, including a curvilinear axis and parameters relating the position of the bases to this axis. It additionally provides a full analysis of groove widths and depths. Curves+ can also be used to analyse molecular dynamics trajectories. With the help of the accompanying program Canal, it is possible to produce a variety of graphical output including parameter variations along a given structure and time series or histograms of parameter variations during dynamics.
Polarimetric analysis of two-mode, elliptical-core optical fibers (1991)

We show that linearly polarized light launched at different angles with respect to the major axis of a two-mode, elliptical-core fiber results in an amplitude-modulated beat-length pattern in the far field. The variation of the output pattern is explained theoretically and confirmed experimentally. A polarizer placed at the output of the fiber is shown to eliminate the amplitude modulation in the output signal. A simple theoretical model, based on the weakly guiding assumption, is shown to be helpful in determining few-mode fiber sensor parameters in practical systems.
Surface shield: device to reduce personnel radiation exposure. (1986)

A simple device is described that can reduce personnel exposure from scatter radiation by up to 75%. The device consists of an oblong piece of shielding (0.75-mm lead equivalent) that is taped to the side of the patient during percutaneous renal stone removal and other interventional procedures. Contrary to other shields and barriers, this does not interfere with access to the patient. Scatter exposure data from phantom studies are presented and the rationale for surface shielding discussed.
TRANSMISSION OF THE COMMON COLD TO VOLUNTEERS UNDER CONTROLLED CONDITIONS. IV. SPECIFIC IMMUNITY TO THE COMMON COLD* (1959)

Although the common cold is the most prevalent illness of humans, information on the antigenicity of the infectious agents and the immune response of the host to the infection has been difficult to obtain. Epidemiologic investigations have led to divergent hypotheses. The frequent repetition of colds, on the one hand, has suggested little or no immunity to reinfection. On the other hand, the diminution or disappearance of colds among isolated populations, even in an arctic climate, is compatible with the belief that persons develop im- munity to specific common cold agents (1, 2). Analysis of the influence of age upon susceptibility also is inconclusive with regard to acquired im- munity to the common cold. The frequency of common colds tends to decline with age beyond childhood (3-5), but in a survey of colds within a group of families apparent evidence of brief im- munity was observed after infection only among children (3).
Intermittent Hypoxic Training: Fact and Fancy (2002)

Intermittent hypoxic training (IHT) refers to the discontinuous use of normobaric or hypobaric hypoxia, in an attempt to reproduce some of the key features of altitude acclimatization, with the ultimate goal to improve sea-level athletic performance. In general, IHT can be divided into two different strategies: (1) providing hypoxia at rest with the primary goal being to stimulate altitude acclimatization or (2) providing hypoxia during exercise, with the primary goal being to enhance the training stimulus. Each approach has many different possible application strategies, with the essential variable among them being the "dose" of hypoxia necessary to achieve the desired effect. One approach, called living high-training low, has been shown to improve sea-level endurance performance. This strategy combines altitude acclimatization (2500 m) with low altitude training to ensure high-quality training. The opposite strategy, living low-training high, has also been proposed by some investigators. The primacy of the altitude acclimatization effect in IHT is demonstrated by the following facts: (1) living high-training low clearly improves performance in athletes of all abilities, (2) the mechanism of this improvement is primarily an increase in erythropoietin, leading to increased red cell mass, V(O2max), and running performance, and (3) rather than intensifying the training stimulus, training at altitude or under hypoxia leads to the opposite effect - reduced speeds, reduced power output, reduced oxygen flux - and therefore is not likely to provide any advantage for a well-trained athlete.
