A new ferroelectric memory device, metal-ferroelectric-semiconductor transistor (1974)

The ferroelectric field effect has successfully been demonstrated on a bulk semiconductor (silicon) using a thin ferroelectric film of bismuth titanate (Bi <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">4</inf> Ti <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</inf> O <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">12</inf> ) deposited onto it by RF sputtering. A new memory device, the metal-ferroelectric-semiconductor transistor (MFST); has been fabricated. This device utilizes the remanent polarization of a ferroeletric thin film to control the surface conductivity of a bulk semiconductor substrate and perform a memory function. The capacitance-voltage characteristics of the metal-ferroelectric-semiconductor structure were employed to study the memory behavior. The details of the study together with a preliminary results on the MFST are presented.
Development and validation of a flow cytometric assay for detecting reactive oxygen species in the erythrocytes of healthy dogs (2021)

Flow cytometry for the measurement of reactive oxygen species in the erythrocytes of healthy dogs by use of DCFH-DA had acceptable specificity, precision, and stability. Flow cytometry is a promising technique for evaluating intraerythrocytic oxidative stress for healthy dogs.
Effects of Natural Phenolic Compounds on the Antioxidant Activity of Lactoferrin in Liposomes and Oil-in-Water Emulsions (2002)

The effect of natural phenolic compounds on the antioxidant and prooxidant activity of lactoferrin was studied in liposomes and oil-in-water emulsions containing iron. The antioxidants tested with lactoferrin were alpha-tocopherol, ferulic acid, coumaric acid, tyrosol, and natural phenolic extracts obtained from three different extra-virgin olive oils and olive mill wastewater. The natural extracts of olive oils and mill wastewaters were composed mainly of polyphenols and simple phenolics, respectively. Lipid oxidation at 30 degrees C was determined by the formation of hydroperoxides and fluorescent compounds resulting from oxidized lipid interactions. All phenolic compounds showed synergistic properties in reinforcing the antioxidant activity of lactoferrin in lipid systems containing iron. The highest synergistic effects were observed for the phenolic extracts rich in polyphenols of extra-virgin olive oils and lactoferrin. This synergistic effect was higher in liposomes than in emulsions.
Heterogeneities and Geometry of Sedimentary Bodies in a Fluvio-Deltaic Reservoir (1989)

Summary This paper gives the initial results of a two- and three-dimensional (2D and 3D) geological study that aimed at describing reservoir heterogeneities. This study serves as a basis for the conditional simulation of the geometry of a fluvio-deltaic reservoir presented in a companion paper. These two studies should solve the difficult problem of interpolating between wells and thereby the problem of forecasting the extension of sedimentary bodies. The research is being carried out by Inst. Français du Pétrole and Center of Geostatistics, Paris School of Mines. The study was made in the middle Jurassic in Yorkshire, which is very similar to the Brent formation in the North Sea. In the 2D phase, an outcrop consisting of a 1-km [0.6-mile] -long and approximately 30-m [100-ft] -high cliff was described with a photogeological interpretation. The sedimentological representation was carried out by means of several vertical cross sections. In the 3D phase, 36 boreholes were continuously cored and logged behind the cliff over an area of 1 km2 [0.4 sq miles]. The boreholes were about 300 m [985 ft] apart except in one grid where the distance was progressively reduced to 20 m [66 ft]. This phase was designed to follow the evolution of the sedimentary bodies and their physical properties and to compare the correlation that could have been made (1) with fewer boreholes and (2) without the existence of the cliff. These studies provide new tools for understanding and describing the shape and heterogeneities of a reservoir.
A tale of two limits: fundamental properties of photonic-crystal fibers (2008)

We present analytical results that shed new light on the properties of photonic-crystal fibers (optical fibers with periodic structures in their cladding). First, we discuss a general theorem, applicable to any periodic cladding structure, that gives rigorous conditions for the existence of cutoff-free guided modes-it lets you look at a structure, in most cases without calculation, and by inspection give a rigorous guarantee that index-guiding will occur. This theorem especially illuminates the long-wavelength limit, which has proved diffcult to study numerically, to show that the index-guided modes in photonic-crystal fibers (like their step-index counterparts) need not have any theoretical cutoff for guidance. Second, we look in the opposite regime, that of very short wavelengths. As previously identified by other authors, there is a scalar approximation that becomes exact in this limit, even for very high contrast fibers. We show that this "scalar" limit has consequences for practical operation at finite wavelengths that do not seem to have been fully appreciated: it tells you when band gaps arise and between which bands, reveals the symmetry and "LP" degeneracies of the modes, and predicts the scaling of cladding-related losses (roughness, absorption, etc.) as the size of a hollow core is increased.
Fatigue behavior of notched carbon epoxy laminates during reversed cyclic loads (1988)

The relationships between fatigue damage, stress redistribution, and residual stiffness and strength were investigated for notched graphite epoxy laminates during fulIy-reversed cyclic loads. Two material systems, AS4/3501-6 and AS4/1808, two lamination arrangements, (0,45,90,-45)<sub>s</sub>₄ and (0,45,0,-45)<sub>s</sub>₄, and two notch configurations, central hole and opposing semi-circular edge notches, were used to obtain a fundamental understanding of the fatigue effect in specimens under low and high cycle lifetimes. Damage was evaluated with penetrant-enhanced X-ray radiography and Iaminate deply. Tensile and compressive residual strengths were measured at three stages of damage development. A recently developed nondestructive testing technique, Stress Pattern Analysis by Thermal Emission, was implemented to obtain full-field measurements of surface stresses during damage initiation and growth. A new micromechanical theory of the adiabatic thermoelastic effect in Iaminated fiber composites was conceived to assist the interpretation of SPATE measurements.
A Lightweight Threat Detection System for Industrial Wireless Sensor Networks (2016)

Wireless Sensor Networks (WSNs) led the way to new forms of communications, which extend today the Internet paradigm to unforeseen boundaries such as eHealth, intelligent building or smart grid, to name a few. The legacy industry, however, is slower to adopt this technology, mainly for security reasons. Self-managed security systems allowing a quicker detection and better resilience to attacks, may counterbalance this reluctance. In this article, we propose a hybrid threat detection system that involves both centralized decision and local, per-cluster, work repartition and that is designed to run on top of industrial wireless sensor networks. Compared with the literature, we prove that this system is suitable for architectures mainly composed of constrained and sleeping devices, for which it achieves a fair level of autonomous security without prohibitively drawing out energy resources.
Double Double to Double Perovskite Transformations in Quaternary Manganese Oxides (2021)

Abstract Control of cation ordering in ABX 3 perovskites is important to structural, physical and chemical properties. Here we show that thermal transformations of AA′BB′O 6 double double perovskites, where both A and B sites have 1:1 cation order, to (A 0.5 A′ 0.5 ) 2 BB′O 6 double perovskites with fully disordered A/A′ cations can be achieved under pressure in CaMnMnWO 6 and SmMnMnTaO 6 , enabling both polymorphs of each material to be recovered. This leads to a dramatic switch of magnetic properties from ferrimagnetic order in double double perovskite CaMnMnWO 6 to spin glass behaviour in the highly frustrated double perovskite polymorph. Comparison of double double and double perovskite polymorphs of other materials will enable effects of cation order and disorder on other properties such as ferroelectricity and conductivity to be explored.
Determining when 3D reconstruction methods are required in volume PET imaging (2003)

An attempt is made to determine at which point a 3-D reconstruction algorithm is needed for a volume imaging scanner as the axial extent is increased. From simulations of an existing volume PET (positron emission tomography) scanner with a maximum axial acceptance angle ( phi ) of 9 deg, it is shown that a two-dimensional image reconstruction with alpha =9 deg is a compromise between sensitivity, speed, and accuracy compared to a two-dimensional reconstruction with a software limit of alpha =1 deg and a three-dimensional reconstruction with alpha =9 deg. It is also shown that a proposed scanner with alpha =27 deg requires three-dimensional reconstruction in order to achieve maximum sensitivity without unacceptable losses in accuracy.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
Fungal Isolation From Disinfectant Solutions of Contact Lens Storage Cases Among Asymptomatic Users (2014)

The results of this study show that even when contact lens users report compliance for handling, cleaning, and replacement according to the manufacturer's instructions, the potential risk of contact lens-related fungal keratitis still remains.
A GIS based Automated Extraction Tool for the Analysis of Basin Morphometry (2012)

An automated extraction tool was developed through the model builder technique in ArcGIS environment to delineate the basin morphometry. The basic requirements to run this tool are a SRTM data, and a pour point shapefile. The developed model will create necessary data required for morphometric analysis after the processing of the input data. The output from this model will create a number of parameters such as, stream network (Strahler's), aspect, slope, DEM, drainage density, hill shade, and basin boundary in meter square. Before proceeding with the model, there is an option to the user to select the minimum upstream area to which a stream should be counted. This option helps the users to select the range of stream delineation. The slope generated will be in degrees and the drainage density in Sq.km. This technique is very useful for those who work in the field of terrain analysis, hydrology, and watershed analysis as it is easy to use with a single click for the generation of a reliable database for morphometric analysis.
Thermoelectric Properties of Polycrystalline SrZn2Sb2 Prepared by Spark Plasma Sintering (2010)

Compact polycrystalline samples of SrZn2Sb2 [space group $$ P\overline{3} m1 $$ , a = 4.503(1) Å, c = 7.721(1) Å] were prepared by spark plasma sintering. Thermoelectric performance, Hall effect, and magnetic properties were investigated in the temperature range from 2 K to 650 K. The thermoelectric figure of merit ZT was found to increase with temperature up to ZT = 0.15 at 650 K. At this temperature the material showed a high Seebeck coefficient of +230 μV K−1, low thermal conductivity of 1.3 W m−1 K−1, but rather low electrical conductivity of 54 S cm−1, together with a complex temperature behavior. SrZn2Sb2 is a diamagnetic p-type conductor with a carrier concentration of 5 × 1018 cm−3 at 300 K. The electronic structure was calculated within the density-functional theory (DFT), revealing a low density of states (DOS) of 0.43 states eV−1 cell−1 at the Fermi level.
Browser's “search form” issues and countermeasures (2017)

From 2014, we are conducting fixed point observation to crawl SSL/TLS sites using .jp domain URL list extracted from Alexa Top Sites, and investigation on improvement of usage rate of SSL/TLS versions and Export-grade encryption algorithms. Furthermore, paying attention to the server side certificates, since the notation policy of the browser security indicator had recently changed, the green bar is displayed in the URL notation part originally although it uses the EV (Extended Validation) SSL certificate, it is “not safe” though sites that are judged were also found. As a situation similar to this issue, a detailed investigation was conducted on the browser's “search form” issues which are originally described to be safe although it is said to be unsafe due to inadequate site-contents. In this paper, the survey targeted are the websites of regular members belonging to the association which is planning and managing settlement systems of banks and on-line banking login services. We investigated SSL/TLS sites of Top FQDN which are widely announced on paper medium etc, so it was found that about half of them were in normal situation but half had problems such as FQDN mismatch. Moreover we also show the result of manually investigating the influence of the above “search form” issues by carrying out some pattern classification on the path reached from the HTTP (not HTTPS) server of the Top FQDN to the on-line banking login page. Finally, the design guideline of HTTP/HTTPS sites is mentioned as one of countermeasures against this kind of problems.
Evidence for a New Murine Immunoglobulin Heavy Chain Variable Region Gene Family (1987)

In the course of a previous study addressing autoantibody generation in murine models for generalized autoimmune disorders, we observed a nonfunctional immunoglobulin heavy chain transcript in a B cell hybridoma from lupus-prone MRL-Mp-lpr/lpr mice. This transcript, the cDNA sequence of which is presented here, is of general interest for murine immunoglobulin genetics as it cannot be ascribed to any known heavy chain variable region gene (Vh) family by nucleic acid sequence homology criteria and, hence, may represent a new Vh gene family. The sequence showed about equal nucleotide similarity (70-73%) to 3 other Vh gene families (S107, J606, 7183) and less than 65% similarity to members of the remaining 6 Vh gene families. Nucleic acid sequence comparisons with unpublished immunoglobulin sequences uncovered a highly homologous (greater than 95%) functional Vh transcript indicating that the suggested Vh gene family also encodes expressed antibody molecules.

Constructing a metacircular Virtual machine in an exploratory programming environment (2005)

Can virtual machine developers benefit from religiously observing the principles more often embraced for exploratory programming? To find out, we are concurrently constructing two artifacts--a Self VM entirely in Self (the Klein VM), and a specialized development environment--with strict adherence to pure object-orientation, metacircularity, heavy code reuse, reactivity, and mirror-based reflection. Although neither artifact is yet complete, the environ-ment supports many remote debugging and incremental update operations, and the exported virtual machine has successfully run the whole compiler.As a result of our adherence to these principles, there have been both positive and negative consequences. We have been able to find and exploit many opportunities for parsimony. For example, the very same code creates objects in the bootstrap image, builds ob-jects in the running VM, and implements a remote debugger. On the other hand, we have been forced to expend effort to optimize the performance of the environment. Overall, this approach trades off the performance of the environment against the architectural sim-plicity and ease of development of the resulting VM artifact. As computers continue to improve in performance, we believe that this approach will increase in value.

Specification, Development, and Verification of CASCADAS Autonomic Computing and Networking Toolkit (2011)

Increasing complexity, heterogeneity, and dynamism of current networks (telecommunications, ICT, and Internet) are making current computational and communication infrastructures brittle, inefficient, and almost unmanageable. As a matter of fact, computing and storage are progressively embedded in all sorts of nodes and devices that are interconnected through a variety of (wireless and wired) technologies in Networks of Networks (NoNs). Dynamicity, pervasivity, and interconnectivity of future NoNs will increase the complexity of their management, control, and optimization more and more, and will open new challenges for service delivery in such environments. Autonomic communications principles and technologies can provide effective computing and networking solutions overcome these bottlenecks and to foster such challenging evolution. This chapter presents the main concepts of an autonomic communications toolkit designed and developed in the EU project CASCADAS for creating and supervising service networking ecosystems, structured as ensembles of distributed and cooperating autonomic components. Moreover, it describes several use-cases developed for its validation and demonstration and reports the experimental results to assess the toolkit performances. A brief overview of future research directions concludes the chapter.
Antifungal Proteins during Sorghum Grain Development and Grain Mould Resistance (2006)

Abstract Proteins potentially inhibitory to the growth of grain‐moulding fungi in vitro have been identified from sorghum seeds. However, their role in vivo during fungi infection is still not clear. The objective of the present study was to evaluate the presence of antifungal proteins (AFPs) during grain development. Sureño (a grain mould‐resistant line), RTx430 (a grain mould‐susceptible) and their F 1 hybrid, were planted at two moisture levels. Caryopses were collected from each genotype every 7 days after anthesis (DAA) during development and maturity of the grain. Significant levels of grain mould occurred naturally. Levels of four AFPs (sormatin, chitinases, β ‐1,3‐glucanases and ribosomal‐inactivating proteins) were determined using the immunoblotting technique. During grain development (7–35 DAA), Sureño and the F 1 hybrid showed higher levels of sormatin and chitinase than RTx430. RIPs levels in Sureño and the F 1 hybrid were higher than those in RTx430 after 21 DAA. Sormatin, chitinases, β ‐1,3‐glucanases and RIPs levels in Sureño and in the F 1 hybrid were higher than those of RTx430 after grain physiological maturity. AFPs are associated with grain mould resistance because Sureño and the F1 hybrid induce and/or retain higher AFPs levels under grain mould infection pressure than did RTx430.

CONSÓRCIO DE SUBSTITUIÇÃO DE CULTURAS: ALTERNATIVA PARA A PEQUENA PROPRIEDADE RURAL (1993)

No consórcio de substituição de culturas uma segunda cultura é implantada após a primeira ter atingido a antese, mas antes da colheita, ocorrendo menor competição por recursos do ambiente entre as culturas do que no consórcio simultâneo. Por requerer a semeadura manual da segunda cultura a ser implantada, similarmente ao plantio direto, proporciona melhor conservação da umidade e controle da erosão, além de manter a temperatura do solo mais favorável em relação ao sistema de sucessão. Além disso, o efeito do sombreamento exercido pelas folhas remanescentes da primeira cultura pode dificultar o desenvolvimento de ervas daninhas nos estádios iniciais da segunda espécie. No Rio Grande do Sul, diversas culturas apresentam potencial para uso em consórcio de substituição. Para que haja sucesso na sua utilização, entretanto, deve-se ter cuidados com relação à utilização de espécies e cultivares compatíveis, arranjo de plantas adequado, escolha de época apropriada para introdução da segunda cultura e controle eficiente de plantas daninhas durante o desenvolvimento da primeira cultura.
Distinct Hemodynamic Patterns of Septic Shock at Presentation to Pediatric Intensive Care (2008)

The hemodynamic patterns of fluid-resistant septic shock by the time children present to the PICU are distinct, depending on cause, with little overlap. If these findings can be reproduced, then targeting the choice of first-line vasoactive infusions in fluid-resistant shock (vasopressors for central venous catheter-associated infections and inotropes for community-acquired sepsis) should be considered.
