A note on packer, slug, and recovery tests in unconfined aquifers (1978)

Packer, slug, and recovery tests are common procedures for determining the hydraulic conductivity of unconfined formations of low permeability. The volumes of water injected or removed from the borehole are small, so that the water table remains horizontal and the flow is steady. The flow problem is solved by source distributions along the well axis. A simple numerical method and numerical results covering a wide range of the parameters of the problem are presented. The main limitation of the method is the requirement that the active portion of the well length should be much larger (say, 50 times) than the well radius.
CELF6, a Member of the CELF Family of RNA-binding Proteins, Regulates Muscle-specific Splicing Enhancer-dependent Alternative Splicing (2004)

We previously described a family of five RNA-binding proteins: CUG-binding protein, embryonic lethal abnormal vision-type RNA-binding protein 3, and the CUG-binding protein and embryonic lethal abnormal vision-type RNA-binding protein 3-like factors (CELFs) 3, 4, and 5. We demonstrated that all five of these proteins specifically activate exon inclusion of cardiac troponin T minigenes in vivo via muscle-specific splicing enhancer (MSE) sequences. We also predicted that a sixth family member, CELF6, was located on chromosome 15. Here, we describe the isolation and characterization of CELF6. Like the previously described CELF proteins, CELF6 shares a domain structure containing three RNA-binding domains and a divergent domain of unknown function. CELF6 is strongly expressed in kidney, brain, and testis and is expressed at very low levels in most other tissues. In the brain, expression is widespread and maintained from the fetus to the adult. CELF6 activates exon inclusion of a cardiac troponin T minigene in transient transfection assays in an MSE-dependent manner and can activate inclusion via multiple copies of a single element, MSE2. These results place CELF6 in a functional subfamily of CELF proteins that includes CELFs 3, 4, and 5. CELF6 also promotes skipping of exon 11 of insulin receptor, a known target of CELF activity that is expressed in kidney.
Profile Analysis of the Wechsler Intelligence Scale for Children-Revised (1983)

Seventy-seven children referred for psychological evaluations to a school psychology training clinic in Pennsylvania and 192 children referred for psychological evaluations through the public schools in Nebraska had their WISC-R subtest scores profile analyzed, with four distinct profiles identified. Cross-validation indicated that the four profiles were similar across the two samples. Profile elevation, scatter, and shape scores were calculated for each child in the combined samples. The use of these scores in a stepwise multiple regression procedure indicated that profile elevation was the major predictor of academic achievement. Shape values added significant but almost inconsequential variance to the predictions of both Reading and Arithmetic. Scatter in dices did not aid in the prediction of achievement. The meaning and usefulness of WISC-R profile analysis is discussed.
Reduction in Switching Field for a Granular Perpendicular Medium Using Microwave Assisted Magnetic Recording (2008)

This paper describes the basic physics of magnetization switching in the presence of a dc bias and an in-plane radio-frequency (RF) field using a micromagnetic model based on the Landau-Lifshitz-Gilbert formulation for the magnetization dynamics. We start with the case of a uniform granular media at <i xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">T</i> = 0 K without any distributions in grains or medium properties. The switching behavior of this medium is essentially the same as that of a single grain and can be described by replacing <i xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">HK</i> of the grain with <i xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">H</i> ' <i xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">K</i> = <i xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">HK</i> - 4pi <i xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">Ms</i> of the medium. Significantly smaller values of the dc bias field compared to the Stoner-Wohlfarth field are needed to reverse the medium for the assumed medium properties at low damping constant alpha. This reduction in dc bias field is progressively less at higher values of damping constant. However, increasing RF field magnitude can provide a significant reduction in the dc bias field even for high alpha values. As grain size distributions are added, the coherent precession of the medium grains can be sustained only for very short duration due to varying self-demagnetization of individual grains. Once the coherent precession is lost, a higher dc bias field compared to the case of uniform granular medium is required to completely reverse all the grains in the medium. At finite temperature and with the inclusion of grain size and magnetic materials distributions, the coherent precession is completely lost, thereby requiring even larger dc bias field for complete reversal of the grains. However, this dc bias field is still significantly smaller compared to the dc field required without the presence of RF field. The need for smaller dc bias field may mitigate the writeability requirements for high areal density recording.
A liquid crystal mixture for use in smectic liquid crystal display devices (1976)

The transition temperatures of mixtures of 4-cyano-4′-n-octylbiphenyl and 4-cyano-4′-n-decylbiphenyl have been obtained and plotted against composition; the eutectic mixture has a wide smectic range (5–40°C), a narrow nematic range (40–43°C) and appears to be suitable for use in smectic liquid crystal display devices.

Serodiagnosis of Helicobacter pylori-Associated Gastritis with a Monoclonal Antibody Competitive Enzyme-Linked Immunosorbent Assay (1992)

Forty-nine monoclonal antibodies against Helicobacter pylori were screened to investigate their capacity to be used in enzyme-linked immunosorbent assay (ELISA) competitive systems for the serodiagnosis of Helicobacter pylori infection. On the basis of the inhibition pattern showed by the sera of five infected patients, the antibodies were subdivided into five groups. The immunoblotting analysis showed that the antibodies recognized a total of nine different antigenic determinants. In a study of the reaction of the antibodies with 12 isolates of H. pylori a total of 9 antigenic profiles were identified. Two monoclonal antibodies, HpN44 and HpN45, which recognized a 64-kD protein, were inhibited by all 5 positive sera. Antibody HpN45 was labeled with horseradish peroxidase, and the competitive ELISA was compared with an ordinary indirect ELISA in a study of 102 patients undergoing gastroscopy. Seventy-three patients proved to be infected by H. pylori according to urease or histologic tests. The sensitivity and specificity were 90.4% and 89.6%, respectively, for the indirect ELISA and 100% and 89.6% for the HpN45 competitive assay. The three patients who were 'false seropositive' with both serologic tests had atrophic gastritis. The high diagnostic performance and simplicity of the HpN45 monoclonal competitive ELISA make it suitable for routine serodiagnosis of H. pylori infection.
Periodically Rippled Graphene: Growth and Spatially Resolved Electronic Structure (2008)

We grow epitaxial graphene monolayers on Ru(0001) that cover uniformly the substrate over lateral distances larger than several microns. The weakly coupled graphene monolayer is periodically rippled and it shows charge inhomogeneities in the charge distribution. Real space measurements by scanning tunneling spectroscopy reveal the existence of electron pockets at the higher parts of the ripples, as predicted by a simple theoretical model. We also visualize the geometric and electronic structure of edges of graphene nanoislands.
Studies on 3,5‐Diaminopyrazoles: Synthesis of New Polyfunctionally Substituted Pyrazoloazines and Pyrazoloazoles (1987)

Abstract New aminopyrazolo[1,5‐ a ]pyrimidines, pyrazolo[3,4‐ d ]pyrimidines and imidazo[1,2‐ b ]pyrazoles were synthesised from ethyl 3,5‐diaminopyrazole‐4‐carboxylate (1) .
Temperature measurement of particulate surfaces (1970)

A device has been developed for measuring the surface temperature of particles of 250 μm diameter at temperatures in excess of 300°C. The basic component of the instrument is a liquid-nitrogen cooled indium antimonide cell used in conjunction with a mechanical chopper and signal amplifier. A system of two-colour pyrometry is employed in which two narrow bandpass filters, centred on the 3·1 and 4·5 μm wavelengths are alternately interposed in the beam of radiation from the source at a frequency of 100 Hz. The device has been developed especially for determining the surface temperature of captive fuel particles, but has been used in other applications, notably the temperature measurement of heat exchanger surfaces, where its high sensitivity and non-contact mode of operation have proved particularly advantageous.

Integrated Quality System (1987)

<div class="htmlview paragraph">Quality management is rapidly-becoming accepted as a business strategy which extends across all disciplines or an organization. To accomplish this end, the process of evaluating needs, planning approaches, developing methods and implementating the resulting system has emerged as a challenge to companies in the western world. So, most companies have opted for short term approaches that have largely resulted in dismal outcomes. This paper deals with a systems management proceeds which extends from the identification of customer driven quality needs through the actual implementation of an integrated quality system targeted at these needs. Simply stated, the integrated quality system is the systems management process of doing what companies have wanted to do, but have been unable to do to improve their quality.</div>
RNA-Dependent RNA Polymerase 1 from <i>Nicotiana tabacum</i> Suppresses RNA Silencing and Enhances Viral Infection in <i>Nicotiana benthamiana</i>  (2010)

Endogenous eukaryotic RNA-dependent RNA polymerases (RDRs) produce double-stranded RNA intermediates in diverse processes of small RNA synthesis in RNA silencing pathways. RDR6 is required in plants for posttranscriptional gene silencing induced by sense transgenes (S-PTGS) and has an important role in amplification of antiviral silencing. Whereas RDR1 is also involved in antiviral defense in plants, this does not necessarily proceed through triggering silencing. In this study, we show that Nicotiana benthamiana transformed with RDR1 from Nicotiana tabacum (Nt-RDR1 plants) exhibits hypersusceptibility to Plum pox potyvirus and other viruses, resembling RDR6-silenced (RDR6i) N. benthamiana. Analysis of transient induction of RNA silencing in N. benthamiana Nt-RDR1 and RDR6i plants revealed that Nt-RDR1 possesses silencing suppression activity. We found that Nt-RDR1 does not interfere with RDR6-dependent siRNA accumulation but turns out to suppress RDR6-dependent S-PTGS. Our results, together with previously published data, suggest that RDR1 might have a dual role, contributing, on one hand, to salicylic acid-mediated antiviral defense, and suppressing, on the other hand, the RDR6-mediated antiviral RNA silencing. We propose a scenario in which the natural loss-of-function variant of RDR1 in N. benthamiana may be the outcome of selective pressure to maintain a high RDR6-dependent antiviral defense, which would be required to face the hypersensitivity of this plant to a large number of viruses.
High-efficiency and stable optical transmitter using VCSEL-direct-bonded connector for optical interconnection (2007)

A high-efficiency optical transmitter module for PCB (printed circuit board)-based interconnections was fabricated using a bottom-emitting VCSEL. The bottom-emitting VCSEL was directly bonded by an epoxy on a 90 degrees -bent fiber connector which is inserted into the PCB to couple to the fiber layer embedded in the board. A ray trace simulation indicates that close contact between the VCSEL and the connector removes most of the losses due to Fresnel reflection and beam divergence. This tendency was experimentally identified. Thermal dissipation through the epoxy layer and the connector also improves significantly the power characteristics of the VCSEL. The VCSEL after bonding on the connector shows about 40% higher power compared to that of the bare VCSEL at the current showing a peak power before bonding. The results indicate that direct bonding improves both optical and electrical efficiencies. A successful eye diagram at the speed of 5 Gb/s/ch with 850 nm was accomplished from the VCSEL-direct-bonded transmitter module.
Dose optimization of infliximab in patients with rheumatoid arthritis (2013)

Aim: It is well established that tumor necrosis factor (TNF) inhibitors help control disease activity, limit radiographic progression and preserve function in patients with rheumatoid arthritis. However, not all patients respond adequately to initial anti-TNF treatment and some patients lose response over time. Possible treatment modifications include optimizing concomitant disease-modifying antirheumatic drugs, switching to another anti-TNF biologic or another class of agent, or optimizing the dose of the anti-TNF agent. Here we review data on dose optimization of infliximab, with emphasis on dose changes to address inadequate response, nonresponse and loss of response. Method: The authors conducted a literature review to identify studies that evaluated the effect of dose optimization on clinical response in infliximab-treated patients with rheumatoid arthritis. Results: Few well-controlled studies of dose optimization of infliximab have been completed for patients with rheumatoid arthritis, and the evidence supporting efficacy and safety after dose adjustment can be difficult to interpret. Studies of dose optimization in infliximab-treated patients who fail to show initial response, have an inadequate response, or lose response over time are not entirely consistent, but tend to show a pattern of improvement after a dose increase. Conclusion: Dose optimization involves a balance of risks and benefits, and future research should seek to clarify which patients are most likely to benefit from dose optimization without undue increase in risk.
Water uptake, priming, drying and storage effects inCassia excelsa Schrad seeds (2003)

The aims of this study were to evaluate the effects of osmotic potential on the water uptake curve in Cassia excelsa seeds and use the results to analyze the effects of dehydration and storage on primed seed germination. Seeds were imbibed in distilled water and polyethylene glicol (PEG 6000) osmotic solutions at -0.2, -0.4, and -0.6 MPa, at 20 degrees C. The radicle emergence and seed moisture content were evaluated at 6-hour intervals during 240 hours. Afterwards, seeds were primed in distilled water and PEG 6000 solutions at -0.2, -0.4, and -0.6 MPa for 48, 72, 96, and 168 hours at 20 degrees C, followed by air drying and storage for 15 days at 5 degrees C. The lower the osmotic potential, the higher the time required for priming. The osmoconditioning yields benefits with PEG solutions at 0.0 and -0.2 MPa; seed improvements were maintained during storage for 15 days at 5 degrees C, but were reverted by seed drying.

Distributed Intrusion Detection System in a Multi-Layer Network Architecture of Smart Grids (2011)

The advent of the smart grid promises to usher in an era that will bring intelligence, efficiency, and optimality to the power grid. Most of these changes will occur as an Internet-like communications network is superimposed on top of the current power grid using wireless mesh network technologies with the 802.15.4, 802.11, and WiMAX standards. Each of these will expose the power grid to cybersecurity threats. In order to address this issue, this work proposes a distributed intrusion detection system for smart grids (SGDIDS) by developing and deploying an intelligent module, the analyzing module (AM), in multiple layers of the smart grid. Multiple AMs will be embedded at each level of the smart grid-the home area networks (HANs), neighborhood area networks (NANs), and wide area networks (WANs)-where they will use the support vector machine (SVM) and artificial immune system (AIS) to detect and classify malicious data and possible cyberattacks. AMs at each level are trained using data that is relevant to their level and will also be able to communicate in order to improve detection. Simulation results demonstrate that this is a promising methodology for supporting the optimal communication routing and improving system security through the identification of malicious network traffic.

Chemical analysis of surface oxygenated moieties of fluorescent carbon nanoparticles (2011)

Water-soluble carbon nanoparticles were prepared by refluxing natural gas soot in concentrated nitric acid. The surface of the resulting nanoparticles was found to be decorated with a variety of oxygenated species, as suggested by spectroscopic measurements. Back potentiometric titration of the nanoparticles was employed to quantify the coverage of carboxylic, lactonic, and phenolic moieties on the particle surface by taking advantage of their vast difference of acidity (pK(a)). The results were largely consistent with those reported in previous studies with other carbonaceous (nano)materials. Additionally, the presence of ortho- and para-quinone moieties on the nanoparticle surface was confirmed by selective labelling with o-phenylenediamine, as manifested in X-ray photoelectron spectroscopy, photoluminescence, and electrochemical measurements. The results further supported the arguments that the surface functional moieties that were analogous to 9,10-phenanthrenequinone were responsible for the unique photoluminescence of the nanoparticles and the emission might be regulated by surface charge state, as facilitated by the conjugated graphitic core matrix.
Lithium storage in polymerized carbon nitride nanobells (2001)

Polymerized carbon nitride nanobells (CNNBs) have been intercalated by a large amount of Li ions using an electrochemical method. Li nanocrystals are observed on the inside surface of CNNB walls, which is direct evidence that a Li nanocrystal can exist at the micropore structure at a heavy intercalating level. Graphene layers are expanded and become partly disordered by Li intercalation, while after deintercalation, they are reordered to a certain degree, and Li nanocrystals disappear. The samples show a reversible Li storage capacity of 480 mAhg−1, much higher than 330 mAhg−1 of commercial carbon materials used for Li ion batteries.

Assessment of a Markov logic model of crop rotations for early crop mapping (2015)

Detailed and timely information on crop area, production and yield is important for the assessment of environmental impacts of agriculture, for the monitoring of the land use and management practices, and for food security early warning systems. A machine learning approach is proposed to model crop rotations which can predict with good accuracy, at the beginning of the agricultural season, the crops most likely to be present in a given field using the crop sequence of the previous 3–5 years. The approach is able to learn from data and to integrate expert knowledge represented as first-order logic rules. Its accuracy is assessed using the French Land Parcel Information System implemented in the frame of the EU’s Common Agricultural Policy. This assessment is done using different settings in terms of temporal depth and spatial generalization coverage. The obtained results show that the proposed approach is able to predict the crop type of each field, before the beginning of the crop season, with an accuracy as high as 60%, which is better than the results obtained with current approaches based on remote sensing imagery.
