A one volt four-quadrant analog current mode multiplier cell (1995)

This paper describes a four-quadrant analog multiplier cell that can operate below one volt dc bias. This new multiplier cell is specially designed for low voltage portable communication equipment. The multiplier cell consists of two translinear loops. We have operated this new multiplier cell at as low as 0.8 V. With the exception of the low voltage operation, the output current of the multiplier cell is a true product of the input currents, and there is no limitation on the input dynamic range as with the conventional Gilbert cell.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Determining an anthropometric surrogate measure for identifying low birth weight babies in Uganda: a hospital-based cross sectional study (2013)

This study suggests foot length as the most appropriate predictor for low birth weight in comparison to chest, head, mid-upper arm and thigh circumference in the Uganda setting. Use of low cost and easy to use tools to identify low birth weight babies by village health teams could support community efforts to save newborns.

Manipulation of single DNA molecules by using optically projected images (2009)

A new platform is presented that is capable of manipulating a single DNA molecule based on optically-induced dielectrophoretic forces. The ends of a single DNA molecule are bound with a micro-bead, which is then manipulated by interactions with optical images projected from a commercially available projector. Thus a single DNA molecule is indirectly manipulated by a projected animation pre-programmed using simple computer software. Real-time observation of the manipulation process is made possible by using a fluorescent dye and an oxygen scavenging buffer. Two types of DNA manipulation modes, specifically DNA elongation and rotation, are successfully demonstrated and are characterized. The maximum stretching force can be as high as 61.3 pN for a 10.1 microm bead. Experimental data show that the force-extension curve measured using this platform fits reasonably with the worm-like chain model. The developed platform can be a promising and flexible tool for further applications requiring single molecule manipulation.

The Adventures of Mark Twain by Huckleberry Finn (review) (2011)

Reviewed by: The Adventures of Mark Twain by Huckleberry Finn Elizabeth Bush Burleigh, Robert . The Adventures of Mark Twain by Huckleberry Finn; illus. by Barry Blitt. Atheneum, 2011. [44p]. ISBN 978-0-689-83041-9 $17.99 Reviewed from galleys R* Gr. 2-5. Hot on the heels of Susy Clemens, in Barbara Kerley's The Extraordinary Mark Twain (According to Susy), BCCB 3/10, comes a rival Mark Twain child biographer, of sorts—Huckleberry Finn himself. With Burleigh's, ahem, editorial assistance, Huck recreates his creator, one might say, in his own homespun voice: "Sam tried soldierin'. But it didn't take. There wasn't much sand in his craw for killin' people. And . . . he was very unfavorable to bein' killed hisself." Huck not only effectively and wittily conveys the basics of his literary father's life, but he also displays an excellent grasp of the critiques addressed to Twain's work by both contemporaries and later generations: "Before I came along, most folks wouldn't pay no attention to a story 'bout a no-account boy. . . . And they wouldn't like that my words ain't always presented in the King's English." Huck is assisted in his authorial debut by Barry Blitt, whose spidery line-and-watercolor paintings echo the fluid ink work of Robert Andrew Parker and the spot-on caricature of John Hendrix. Our "author" admits he "left a lot out," but he slyly puts responsibility for any of his work's [End Page 321] shortcomings on Twain himself: "I coulda throwed more style into it, but I can't do that very handy, not being brought up to it." Fortunately, his editor supplies additional data in an appended note, and as to style—well, I reckon most kids'll think he done just fine.

Industry: French firms feel the pinch (1992)

French companies expect to increase their internal research and development spend by only 1.5% in real terms this year, according to a Ministry of Research and Space (MRE) survey of RD the French gross national product (GNP) is expected to grow by only 2.2% over the same period (with inflation at 3%). Staff numbers in R&D are also expected to increase by 1%, compared with a 3% rise last year, against a background of a 1.7% drop in total staff. Spending on external R&D is, however, expected to fall by 2% in real terms.
Advances in DRAM interfaces (1995)

New advanced architectures in DRAM interfaces seek to close the ever-widening performance gap between DRAM and microprocessor and to break the bandwidth bottleneck in graphics systems. We present an overview of five of these interfaces: EDO, SDRAM, RDRAM, CDRAM, and 3D-RAM. EDO will soon replace conventional DRAM, and SDRAM will partly take over in 66-MHz and higher frequency systems. Other interfaces will initially find target markets that exploit their unique features, and then seek wider market acceptance. Eventually, advances in DRAM will contribute to the trend toward a system on a chip.

Current insights on use of growth factors as therapy for Intervertebral Disc Degeneration (2018)

Chronic low back pain is a critical health problem and a leading cause of disability in aging populations. A major cause of low back pain is considered to be the degeneration of the intervertebral disc (IVD). Recent advances in therapeutics, particularly cell and tissue engineering, offer potential methods for inhibiting or reversing IVD degeneration, which have previously been impossible. The use of growth factors is under serious consideration as a potential therapy to enhance IVD tissue regeneration. We reviewed the role of chosen prototypical growth factors and growth factor combinations that have the capacity to improve IVD restoration. A number of growth factors have demonstrated potential to modulate the anabolic and anticatabolic effects in both in vitro and animal studies of IVD tissue engineering. Members of the transforming growth factor-β superfamily, IGF-1, GDF-5, BMP-2, BMP-7, and platelet-derived growth factor have all been investigated as possible therapeutic options for IVD regeneration. The role of growth factors in IVD tissue engineering appears promising; however, further extensive research is needed at both basic science and clinical levels before its application is appropriate for clinical use.
<title>Linear electrostatic micromotors for nano- and micro-positioning</title> (2004)

The functioning of the linear step electrostatic film micromotors with the short controlling pulse (less then 100-200 µs) is studied to create nano- and micro-positioners. The theoretical study of the step movement of the given mass in this time frame is carried out. The results of the experimental studies of the multipetal reciprocal micromotors created on the basis of La modified Ba<sub>0.5</sub>Sr<sub>0.5</sub>Nb<sub>2</sub>O<sub>6</sub> ferroelectric films with 1-3 μm thickness are shown. The petals were made of beryllium bronze. It is shown that the electrostatic rolling can last less than 50 μs, and the process of separating two surfaces (the metal and the ferroelectric) can last less than 1 μs. These parameters allow one to operate the micromotor at 1-10 kHz frequency, and the propulsion force in the beginning (the first 20-100 μs) of the electrostatic rolling can be as high as 1-10 N per 1 mm<sup>2</sup> of the rolling surface with the voltage pulse amplitude of 40-50 V. The possibility of obtaining moving plate (MP) step in the nanometer range is studied, as well as the precision of these steps during the continuous MP movement with the different clock frequencies and durations of the voltage pulses. The recommendations are given to improve the accuracy and the speed of the positioning in the nano- and micro-movement range. Possible fields of micromotor application are micromechanics, including precision micromechanics, microelectronics, microrobots, microoptics, microscanners, micropumps (e.g. in the jet printers), micro flying vehicles etc.

Federalism—Russian Style: <i>The Federation Provisions in Russia’s New Constitution</i> (1995)

The constitution adopted by Russia in December 1993 has been criticized for contributing to tensions between Moscow and the periphery. But the real weakness of the new constitution rests in the extensive powers it concentrates in the hands of the president, not in its federation provisions.
Investigation of the Hydrate Plugging and Non-Plugging Properties of Oils (2010)

Three laboratories (Norwegian Institute of Science and Technology [NTNU], Institut Français du Pétrole [IFP], and the Colorado School of Mines [CSM]) determined hydrate plug formation characteristics in three oils, each in three conditions: (1) in their natural state, (2) with asphaltenes removed, and (3) with naturally occurring acids removed from the oil. The objective was to determine the major variables that affect hydrate plugging tendencies in oil-dominated systems, to enable the flow assurance engineer to qualitatively assess the tendency of an oil to plug with hydrates. In the past, it was indicated that chemical effects, for example, water-in-oil/hydrate-in-oil (emulsion/dispersion) stability, prevented hydrate plugs. For example, deasphalted oils provided low emulsion/dispersion stability and thus hydrate particles aggregated. In contrast pH 14-extracted oils were reported to remove stabilizing naphthenic acids, causing asphaltene precipitation on water/hydrate droplets, stabilizing the emulsion/dispersion to prevent aggregation and pluggage. This work suggests that in addition to chemistry, shear can enable plug-free operation in the hydrate region. High shear can prevent hydrate particle aggregation, while low shear encourages particle aggregation and plugging. As a result, flow assurance engineers may be able to forecast hydrate plug liability of an oil by a combination of chemistry and flow variables, such as: a) measurements of live oil emulsion stability, b) predictions of flow line shear, and c) knowledge of water cut. Plug formation qualitative trends are provided for the above three variables. Implications for flow assurance are given.
Immunohistochemical evidence of neuroprotection by R(?)-deprenyl andN-(2-hexyl)-N-methylpropargylamine on DSP-4-induced degeneration of rat brain noradrenergic axons and terminals (1996)

DSP-4 [N-(2-chloroethyl)-N-ethyl-2-bromobenzylamine] is a potent neurotoxin highly selective to the locus coeruleus noradrenaline (NA) system. Previous biochemical studies have shown that the monoamine oxidase-B (MAO-B) inhibitors, R(-)-deprenyl and (+/-)2-HxMP [N-(2-hexyl)-N-methylpropargylamine], are able to prevent DSP-4 induced NA depletion in the mouse hippocampus. It is not quite certain, however, whether this actually represents neuroprotection of NA axons or a metabolic effect due to inhibition of MAO activity. Employing dopamine-beta-hydroxylase immunohistochemical and image analysis methods, we have shown that 92% and 84% of NA nerve fibers in the rat hippocampus are spared from DSP-4 neurotoxicity by a single pretreatment dose of either R(-)-deprenyl or (+/-)2-HxMP respectively. Similar neuroprotective effects of R(-)-deprenyl and (+/-)2-HxMP were also observed in the cerebral cortex, thalamus, amygdaloid complex and cerebellum. This is the first morphological evidence demonstrating that R(-)-deprenyl and (+/-)2-HxMP can indeed protect noradrenergic axons of locus coeruleus origin against DSP-4 neurotoxicity.
Labeled Metronidazoles as Potential New Agents for Amebic Hepatic Abscess Imaging (1975)

Two new radiopharmaceuticals were developed as possible agents for demonstrating the presence of hepatic amebic abscesses by selective accumulation of these agents in the abscess contents. These agents are: 131I-labeled Bromometronidazole, that has been shown to possess some of the antibiotic activity of metronidazole or Flagyl; and a Technetium 99m-penicillamine-Flagyl complex. A method of radioiodination has been devised which can be performed in radiopharmaceutical laboratories. Both radiopharmaceuticals are of very low toxicity. Distribution studies in animals show accumulation in the liver and elimination by way of the gallbladder. Scintillation camera studies depict a rapid uptake by the liver with subsequent biliary excretion. Animal models for the study of hepatic amebic abscesses are not available. A human patient with suspected amebic abscesses has been studied with negative findings that were confirmed at surgery. Collaborative studies are now in progress in several areas of the world where amebiases is endemic.
Bactericidal effect of extracorporeal shock waves on Staphylococcus aureus (2000)

Despite considerable knowledge about the effects of shock waves on eukaryotic soft tissues, no data are available concerning their effect on prokaryotic micro-organisms. In vitro studies on the bactericidal effect of extracorporeal shock waves on staphylococci were performed with energy levels that are standard for the disintegration of calculi. Suspensions containing 10(4)-10(5) cfu of Staphylococcus aureus/ml were sealed in plastic tubes and exposed to shock waves, resulting in a mean decrease of 3.1 log(10). Whereas impulse rates of > or =350 resulted in a decrease of cfu/ml equalling the detection limit, lower numbers of impulses did not result in an appreciable bactericidal effect. The bactericidal effect of extracorporeal shock waves might provide the basis for the development of novel therapeutic strategies for bacterial infections.
Coordinating advice and actual treatment (2002)

The author focuses on identifying the current treatment, allowing time for therapy to take effect, and coordinating the advice with the actual execution of treatment plans. These problems were encountered during the implementation of an expert system for treatment of diabetic ketoacidosis. The programming system, called the temporal control structure (TCS), is a temporal data dependency manager that maintains a temporal database and automatically updates decisions that are based on information that changes. Data can be stored either as point events or as intervals. When an expert system is programmed, the data dependencies of all of the decisions are declared. By tracing the dependency structure, the TCS can assure the complete propagation of information as it arrives and changes. The programmer is relieved of the burden of explicitly calling for the recalculation of affected decisions. The use of the TCS allows the flexible implementation of reasoning systems that manipulate data that arrives during the course of the consultation.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Statistical Performance Evaluation of Biometric Authentication Systems Using Random Effects Models (2007)

As biometric authentication systems become more prevalent, it is becoming increasingly important to evaluate their performance. This paper introduces a novel statistical method of performance evaluation for these systems. Given a database of authentication results from an existing system, the method uses a hierarchical random effects model, along with Bayesian inference techniques yielding posterior predictive distributions, to predict performance in terms of error rates using various explanatory variables. By incorporating explanatory variables as well as random effects, the method allows for prediction of error rates when the authentication system is applied to potentially larger and/or different groups of subjects than those originally documented in the database. We also extend the model to allow for prediction of the probability of a false alarm on a "watch-list" as a function of the list size. We consider application of our methodology to three different face authentication systems: a filter-based system, a Gaussian Mixture Model (GMM)-based system, and a system based on frequency domain representation of facial asymmetry.
A Taxonomy of Similarity Mechanisms for Case-Based Reasoning (2008)

Assessing the similarity between cases is a key aspect of the retrieval phase in case-based reasoning (CBR). In most CBR work, similarity is assessed based on feature value descriptions of cases using similarity metrics, which use these feature values. In fact, it might be said that this notion of a feature value representation is a defining part of the CBR worldview-it underpins the idea of a problem space with cases located relative to each other in this space. Recently, a variety of similarity mechanisms have emerged that are not founded on this feature space idea. Some of these new similarity mechanisms have emerged in CBR research and some have arisen in other areas of data analysis. In fact, research on kernel-based learning is a rich source of novel similarity representations because of the emphasis on encoding domain knowledge in the kernel function. In this paper, we present a taxonomy that organizes these new similarity mechanisms and more established similarity mechanisms in a coherent framework.
Application-aware optimization of redundant resources for the reconfigurable self-healing eDNA hardware architecture (2011)

In this paper we are interested in the mapping of embedded applications on a dynamically reconfigurable self-healing hardware architecture known as the eDNA (electronic DNA) architecture. The architecture consists of an array of cells interconnected through a 2D-mesh topology. Each cell consists of a processor and an Arithmetic Logic Unit (ALU). Applications are modeled as task graphs. We propose a Tabu Search-based approach for the mapping of an application to the reconfigurable architecture, such that the performance is maximized. When faults occur, the self-healing moves the affected functionality to spare-cells. We optimize the number and placement of spare-cells such that the performance overhead is minimized in the fault-free scenario and the application degrades gracefully in case of faults. This has been done using three different spare-cell placement strategies. We use Monte Carlo simulation to determine the average performance overhead increase due to fault occurrences. The approach has been evaluated using a large number of benchmarks and have shown that the performance loss is reduced with 16% for the best spare-cell placement strategy.
RAMO: management network for telecommunications environment equipment (2005)

The RAMO network is the fundamental tool for operating the technical environment equipment of telecommunications centres which concern the power supply, cooling system, building surveillance, access control, security, EMC and electrostatic environment. It implements functions which make it possible to analyse the quality of the equipment's performance in operation, to precisely identify equipment failures to reduce their mean time to repair. The type of equipment included in this network varies depending on the size of the centre which houses it. It comprises the power supply systems, consisting of an electrical generator, an AC distribution cabinet, a conversion and power storage cabinet from the Alfatel range, catering for all power requirements from 2.5 kVA to 60 kVA, and from the Geode range for power greater than 100 kVA, together with the cooling systems and uninterruptible power supplies. The networking of all these items of equipment on an X.25 protocol using France Telecom's operating architecture comprises the RAMO network.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
