Look-ahead seek correction in high-performance CD-ROM drives (1998)

As the performance of CD-ROM drives continues to increase, special attention should be paid to any element in the system that disturbs the desired specifications. When very low access times are considered, it is mandatory to reach the target track within only one seek action, i.e. without any consequent retry or correction seek. Many CD-ROM drives count the tracks crossed during seeking and, by comparing this count with the pre-calculated seek length, the exact target location can be detected. This paper considers the error that affects the track-counting mechanism due to the rotating disc spiral. It is shown that, for a given seek length, the number of crossed tracks differs between outside- and inside-oriented seeks. The involved equations are derived and an algorithm proposed for determining the correct number of tracks to be crossed during a seek action. The proposed algorithm, which is optimized for microprocessor implementation, relies on two look-up tables and a learning scheme that allows look-ahead seek correction for both spiral rotation and system tolerances.
Laboratory tests for diagnosis of autoimmune diseases. (1975)

1. Antimitochondrial antibody titers of 1:160 are practically diagnostic of primary biliary cirrhosis [71]. Serum antimitochondrial antibody titers of less than 1:16 are seen in 10% of cases of primary biliary cirrhosis. The antimitochondrial antibodies are usually absent in jaundiced patients with extrahepatic obstruction, drug sensitivity, and viral hepatitis. 2. Anti-smooth-muscle antibodies are noted in the various autoimmune liver disorders, viral hepatitis, infectious mononucleosis, malignancy, and intrinsic bronchial asthma. The smooth muscle antibody test helps in the differential diagnosis of lupoid hepatitis vs. systemic lupus erythematosus. The anti-smooth-muscle antibodies are usually absent in systemic lupus erythematosus. 3. The antinuclear antibody is frequently positive in the autoimmune liver diseases. In cases of chronic aggressive hepatitis associated with a high titer of antinuclear antibody the prognosis is usually grave. 4. The presence of antimicrosomal liver and kidney antibody is indicative of chronic aggressive liver disease, which is different from the classic lupoid hepatitis [95, 97]. 5. Hepatitis-B-antigen assay should be performed routinely to exclude viral hepatitis, type B. Heterophile antibody tests should done when the possibility of infectious mononucleosis must be considered. 6. Serum immunoglobulin determinations are of secondary importance in the laboratory diagnosis of autoimmune liver disorders. There is usually a polyclonal elevation of the major immunoglobulin in most chronic parenchymal liver diseases[48].
Kinematics of the elbow. (1981)

Previous studies of elbow kinematics produced conflicting results because of technical limitations. Kinematic analyses of eight normal elbows (four in cadavera and four in living subjects) using true lateral roentgenograms made by a special technique showed that flexion occurs about a single axis. This axis passes through the centers of the arcs outlined by the bottom of the trochlear sulcus and the periphery of the capitellum. Motion of the joint surfaces is of a sliding type except at the extremes of flexion and extension where rolling motion occurs. The carrying angle of the forearm remains constant as the elbow flexes. Based on these findings, total elbow prostheses ideally should be uniaxial, with the axis of flexion of the prosthesis the same as the axis of the normal joint.
Definition of common PLC MIB and design of MIB Mapper for multi-vendor PLC network management (2008)

Power Line Communication (PLC) is an evolving technology which uses the existing power lines for data transmission. Like any other communication networks, PLC networks need to be managed for efficient use of resources and secure operations. Major PLC chipset and modem vendors are trying to provide network management solutions using SNMP by defining their own management information, but it is not sufficient to manage a multi-vendor PLC network comprised of PLC devices from heterogeneous vendors. In this paper, we propose an integrated management method of multi-vendor PLC network. We define a common PLC MIB by analyzing existing proprietary PLC MIBs and design a common PLC MIB Mapper for managing existing PLC devices without the support of common PLC MIB. Our work can be a reference model for integrated PLC network management to PLC vendors, and contribute an international standardization for PLC network management.
An Optimal Discriminant Plane (1970)

In solving pattern classification problems, many researchers have successfully used the Fisher linear discriminant as the optimal linear method for discriminating between vector samples from two classes. With the introduction of on-line, interactive, graphic systems, it has become conveniently possible to extend the discrimination logic to piecewise linear methods. This paper describes such a method which is being used in the on-line pattern analysis and recognition system (OLPARS).
Vision-Based Tactile Sensing and Shape Estimation Using a Fluid-Type Touchpad (2012)

In this paper, we propose a new method to estimate the shape and irregularity of objects by a vision-based tactile sensor, which consists of a CCD camera, LED lights, transparent acrylic plate, and a touchpad which consists of an elastic membrane filled with translucent red water. Intensities of red, green and blue bands of the traveling light in the touchpad are analyzed in this study to estimate the shape/irregularity of the object. The LED light traveling in the touchpad is scattered and absorbed by the red pigment in the fluid. The depth of the touchpad is estimated by using the intensity of the light obtained from the red-green-blue (RGB) values of the image, in consideration of the scattering and reflection effects. The reflection coefficient that depends on the shape of the membrane, was decoupled in the proposed formulation. The intensity of the traveling light is represented with the geometrical parameters of the touchpad surface. In order to reduce the approximation error caused by unmodeled factors, we compensate the error by using a function of the deformation of the membrane. The validation of the proposed method is confirmed through experimental results.
Lithium Resources and Production: Critical Assessment and Global Projections (2012)

This paper critically assesses if accessible lithium resources are sufficient for expanded demand due to lithium battery electric vehicles. The ultimately recoverable resources (URR) of lithium globally were estimated at between 19.3 (Case 1) and 55.0 (Case 3) Mt Li; Best Estimate (BE) was 23.6 Mt Li. The Mohr 2010 model was modified to project lithium supply. The Case 1 URR scenario indicates sufficient lithium for a 77% maximum penetration of lithium battery electric vehicles in 2080 whereas supply is adequate to beyond 2200 in the Case 3 URR scenario. Global lithium demand approached a maximum of 857 kt Li/y, with a 100% penetration of lithium vehicles, 3.5 people per car and 10 billion population.

Beyond One-Electron Reaction in Li Cathode Materials:   Designing Li<sub>2</sub>Mn<i><sub>x</sub></i>Fe<sub>1</sub><sub>-</sub><i><sub>x</sub></i>SiO<sub>4</sub> (2007)

Li2MnSiO4 has been identified recently as one of the first cathode battery materials that, at least in principle, could exchange more than 1 lithium per redox-active transition metal ion. In this article, we analyze experimentally and by computer simulations based on density functional theory (DFT) why actual experiments have not confirmed these expectations. We show that Li2MnSiO4 is unstable upon delithiation, with a strong tendency to amorphize. Detailed DFT calculations further indicate that it might be possible to obtain a stable material with a reversible exchange of more than one Li per formula unit (FU) by using an appropriate Mn/Fe mixture (solid solution) with a general formula Li2MnxFe1-xSiO4.
Isolation and Characterization of Ca2+-sensitive Mutants of Saccharomyces cerevisiae (1986)

Thirty Ca2+-sensitive (cls: calcium sensitive) mutants of Saccharomyces cerevisiae were isolated by replica-plating. These mutants, which each had a single recessive chromosomal mutation, were divided into 18 complementation groups. Some cls mutants showed a phenotype of specific sensitivity to Ca2+, while others showed phenotypes of sensitivities to several divalent cations. From measurements of the calcium contents and initial rates of Ca2+ uptake of the cls mutants, 16 of the 18 cls complementation groups were classified into four types: type I mutants (cls5, cls6, cls13, cls14, cls15, cls16, cls17, and cls18) had both elevated calcium contents and increased uptake activities. A type II mutant (cls4) had a normal calcium content and normal uptake activity; type III mutants (cls1, cls2 and cls3) had elevated calcium contents but normal initial rates of Ca2+ uptake; type IV mutants (cls8, cls9, cls10 and cls11) had normal calcium contents but increased initial rates of Ca2+ uptake. Two of the mutants (cls7 and cls12) had intermediate biochemical properties. The primary defects of these four types of cls mutants were considered in terms of the Ca2+ transport system(s). Both type I and type III mutants, which had elevated calcium contents, simultaneously showed a trifluoperazine-sensitive phenotype, suggesting a close correlation of this phenotype with elevated calcium content. In addition, all type IV mutants were unable to utilize nonfermentable sugars. One CLS gene, CLS7, was located on the left arm of chromosome V.
Novel Semiconducting Electrodes for the Photosensitized Electrolysis of Water (1977)

The preparation of novel semiconducting electrodes, based on polycrystalline titanium dioxide having exceptionally good current-voltage characteristics, is reported. These electrodes are formed by mixed oxide TiO/sub 2/-M/sub x/O/sub y/ deposits on metallic titanium substrates, M being a divalent or trivalent element. The mixed oxide coatings were prepared by spraying a solution containing, for example, chlorides of both metals (elements) entering the film composition on Ti metal and heating at approximately 450/sup 0/C in air to decompose the chlorides. Several layers, generally between 6 and 12, were deposited on each substrate. The electrodes were finally activated in argon at 600 to 800/sup 0/C during 30 to 60 min. The current-potential characteristics of the mixed oxide electrodes (area 0.9 cm/sup 2/) were measured in a two compartment cell using 1N sodium hydroxide solution. Results are presented and discussed.
Repolarization of the membrane potential of blood platelets after complement damage: evidence for a Ca++ -dependent exocytotic elimination of C5b-9 pores (1986)

Gel-filtered blood platelets exposed to complement proteins C5b-9 have previously been shown to undergo a reversible depolarization of membrane potential (Em) in the absence of lytic plasma membrane rupture. In this paper, we examine the mechanism by which C5b-9 damaged platelets restore their basal electrochemical state, despite increased ion conductance due to membrane insertion of these cytolytic serum proteins. Repolarization of Em after formation of the C5b-9 membrane pore is shown to be accompanied by a Ca++-dependent vesiculation of the platelet surface, which results in the release of these proteins from the plasma membrane and a restoration of the membrane's functional integrity. This exocytotic elimination of C5b-9 complexes from the plasma membrane is accompanied by a ouabain-inhibitable repolarization of Em, which presumably reflects restoration of transmembrane cation gradients by the plasma membrane Na/K ATPase. The role of external Ca++ in the platelet's response to membrane-insertion of the C5b-9 proteins is discussed both in the context of the known cellular effects of this ion and in the context of recent observations suggesting sublytic changes in platelet function after complement-mediated plasma membrane damage.

Inactivation of Influenza A Virus on Copper versus Stainless Steel Surfaces (2007)

ABSTRACT Influenza A virus particles (2 × 10 6 ) were inoculated onto copper or stainless steel and incubated at 22°C at 50 to 60% relative humidity. Infectivity of survivors was determined by utilizing a defined monolayer with fluorescent microscopy analysis. After incubation for 24 h on stainless steel, 500,000 virus particles were still infectious. After incubation for 6 h on copper, only 500 particles were active.
Automatic editing of footage from multiple social cameras (2014)

We present an approach that takes multiple videos captured by social cameras---cameras that are carried or worn by members of the group involved in an activity---and produces a coherent "cut" video of the activity. Footage from social cameras contains an intimate, personalized view that reflects the part of an event that was of importance to the camera operator (or wearer). We leverage the insight that social cameras share the focus of attention of the people carrying them. We use this insight to determine where the important "content" in a scene is taking place, and use it in conjunction with cinematographic guidelines to select which cameras to cut to and to determine the timing of those cuts. A trellis graph representation is used to optimize an objective function that maximizes coverage of the important content in the scene, while respecting cinematographic guidelines such as the 180-degree rule and avoiding jump cuts. We demonstrate cuts of the videos in various styles and lengths for a number of scenarios, including sports games, street performances, family activities, and social get-togethers. We evaluate our results through an in-depth analysis of the cuts in the resulting videos and through comparison with videos produced by a professional editor and existing commercial solutions.
High Sensitivity Portable Neutron Detector for Fissile Materials (2006)

Efforts to contain weapons of mass destruction have recently intensified, in response to increasing terrorist activities worldwide. The ultimate scenario for nuclear terrorism involves the smuggling of nuclear weapons, or the material to make them, and subsequent detonation in densely populated cities. Widespread monitoring in ports of entry is part of the solution proposed by experts. We propose a portable, economical monitor with high sensitivity for both neutron and gamma detection. It consists of a close-packed array of many thin-walled copper straws, lined with a 1 /spl mu/m thick coating of enriched boron carbide (/sup 10/B/sub 4/C). Neutrons are converted in /sup 10/B, while gammas are converted in Cu. We present performance tests for a prototype monitor that has dimensions of 40/spl times/5/spl times/5 cm/sup 3/ and weighs 3.6 kg. Results show a neutron background of 0.03 cps, a thermal neutron sensitivity of 36 cps/nv (18% efficiency), and an angular resolution of 40 degrees (FWHM). We estimate that a monitor of the proposed design (with enriched boron carbide), traveling at 3 mph, can positively detect 230 g of /sup 240/Pu, from a distance of 2.5 m, with 90% sensitivity and with fewer than 1 false alarms every two hours.
Turn-off failures in individual and paralleled MCTs (2002)

A turn-off failure mode in individual MCTs (MOS-controlled thyristors) initiated by a long gate voltage rise-time is identified and analyzed. It is shown to be caused by turn-off current crowding in the MCT. In addition, a differential failure mode in paralleled devices is demonstrated, in which the slower of the two MCTs fails to turn off. It is caused by the Miller effect, which decreases the turn-off gate voltage rise-time for the device with the longer turn-off delay.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Orientación vocacional hacia la carrera de ingeniería agropecuaria desde la perspectiva de las Tics (2011)

El trabajo aborda una problemática de la escuela cubana: la orientación vocacional, enfocada hacia las especialidades más necesarias en un territorio acorde a sus características sociales y económicas. La idea surge a partir de las insuficiencias en la orientación vocacional hacia la Ingeniería Agropecuaria, dado el bajo nivel de ingreso a la especialidad y la necesidad de buscar nuevos profesionales para materializar los planes propuestos por el territorio.
Some Rigorous Results for a Model Imperfect Gas (1959)

We show that the classical similarity relations and virial theorem imply particular forms for the internal energy and the equation of state in systems where the potentials are homogeneous of degree n. We also show that for these systems the laws of mechanics imply that the differential of entropy is exact. We deduce rigorously some experimental results which must hold for any gas whose constituent particles interact by means of a homogeneous potential. One physical situation in which this model may be expected to be valid is the case of a totally ionized gas with a superimposed radiation field.
Molecular cloning and expression of an extracellular nuclease of Serratia marcescens in Escherichia coli (1985)

The gene encoding an extracellular nuclease of Serratia marcescens was cloned in Escherichia coli using the vector pBR322. Transformants were selected by their ability to grow in the presence of ampicillin, and nuclease-positive clones were detected on a commercially available DNase test agar. The production of a nuclease could be detected in recombinant strains and enzyme activity was found in culture supernatants of such strains. Deletion derivatives of the parental recombinant plasmid were constructed to define the region of DNA encoding the expression of the nuclease. The smallest DNA fragment found to produce the nuclease was determined to be 2.2 kb in length, although a somewhat smaller fragment appeared to be partially active.
Herbicide Effects on Weed Control and Shoot Growth of Young Apple (<i>Malus sylvestris</i>) and Peach (<i>Prunus persica</i>) Trees (1994)

Field experiments were conducted at two locations in Virginia to evaluate the following herbicides: alachlor, diphenamid, diuron, metolachlor, napropamide, norflurazon, oryzalin, oxyfluorfen, paraquat, pendimethalin, and simazine. One experiment involved newly-transplanted apple trees; the others, three in apple and one in peach trees, involved one-year-old trees. Treatments were applied in the spring (mid-April to early-May). Control of annual weed species was excellent with several treatments. A broader spectrum of weeds was controlled in several instances when the preemergence herbicides were used in combinations. Perennial species, particularly broadleaf species and johnsongrass, were released when annual species were suppressed by the herbicides. A rye cover crop in nontreated plots suppressed the growth of weeds. New shoot growth of newly-transplanted apple trees was increased with 3 of 20 herbicide treatments and scion circumference was increased with 11 of 20 herbicide treatments compared to the nontreated control. Growth of one-year-old apple trees was not affected. Scion circumference of one-year-old peach trees was increased with 25 of 33 herbicide treatments.
Surface Yielding of Metals by X-ray Diffraction (1993)

Surface yielding of metallic material was measured with strain gage and X-ray diffraction methods. The results show that.when the residual stress in the transverse direction is involved,the surface yield strength should be evaluated with biaxial Mises criterion.For a medium carbon high strength steel, the yield strength of the bulk material is 581 MPa and the surface yield strengths for 0.05% and 0.1%plastic strain are about 436 MPa and 463 MPa respectively.The 0.05% yield strength will approximately increase to 788 MPa after shot peening.In the early stage of plastic deformation, strain hardening in the surface layer is quite different from that of the bulk sample.
Quasi permanent superconducting magnet of very high field (1993)

We report on persistent field in a quasipermanent magnet made of high temperature superconductor. The material has an average of 40% molar excess of Y, relative to Y1Ba2Cu3O7 and has been irradiated with high energy light ions at 200 MeV. The magnet, which traps 1.52 T at 77.3 K, traps nearly 4 T at 64.5 K. No evidence of giant flux jump or sample cracking was observed.
Single linkage region growing algorithms based on the vector degree of match (1996)

The class of the single linkage region growing (SLRG) algorithms, in which pairs of neighboring pixels are compared for merging, is one of the conceptually simplest approaches to image segmentation. A new normalized coefficient, which measures the degree of match between two multivalued vectors, termed the vector degree of match (VDM), provides the SLRG applications with the metric needed to group adjacent pixel pairs. Two new SLRG algorithms, applied to multiband images and exploiting the VDM criterion, are presented. Their major advantage, in comparison with the SLRG implementations found in the literature, is that they required only one user-defined parameter, the VDM Threshold (VDMT), which is a normalized value featuring local adaptivity and having an intuitive physical meaning. The use of an SLRG module is convenient as the first stage of a structured segmentation procedure featuring the following functional properties: (i) it is implemented sequentially; (ii) it combines single linkage, centroid linkage and hybrid linkage criteria; and (iii) its goal is the detection of image areas characterized by low contrast.
