High resolution current &#x00026; bathymetry determined by nautical X-Band radar in shallow waters (2009)

The wave and current monitoring system WaMoS II is a remote sensing system based on a nautical X-Band radar generally used for navigation and ship traffic control. It has been used in recent years to monitor sea state information from moored platforms, coastal sites and moving vessels. A nautical radar can scan the sea surface over a large area (~ 10 km <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> ) with a high spatial (~7.5 m) and temporal resolution (~2s). Directional wave spectra and standard sea state parameters such as significant wave height, peak wave period and direction can be derived by analyzing the sea surface image sequences. Using the temporal and spatial evolution of the sea surface wave images it is also possible to determine high resolution current and bathymetry information. In the paper a brief introduction into the measuring principle of WaMoS II is given and results of a high resolution current and bathymetric mapping technique for shallow water areas (<20 m) are presented. For validation these results are compared with model data and in-situ measurements.
Pipelining of Arithmetic Functions (1972)

Two addition and three multiplication algorithms were studied to see the effect of pipelining on system efficiency. A definition of efficiency was derived to compare the relative merits of various algorithms and implementations for addition and multiplication. This definition is basically defined as bandwidth cost. Previous comparisons of adders and multipliers have generally been based on latency. In a pipeline environment, latency (or its inverse bandwidth) is not as important. Any bandwidth is possible up to the physical limitations on gate delay variations and pulse skew. The formal definition for efficiency is efficiency = N/D·G where N is the number of bits in the operands, D is the delay (uniform) of each pipeline stage in units of gate delays, and G is the total number of gates, including any used for latching. In cases where gate variations and pulse skewing are well defined, pipelining using the Earle latch results in increased efficiency. The most efficient adder is a maximally pipelined conditional-sum adder (three stages with a delay of four gates per stage). Its efficiency is 6.30×10 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">-3</sup> . The most efficient multiplier is a maximally pipelined tree multiplier (eight stages with a delay of four gates per stage). Its efficiency is 3.48×10 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">-4</sup> .
Design limitations for superconducting A/D converters (1981)

This paper reviews the principle of A/D conversion using superconducting quantum interference and describes the results obtained with this technique At an accuracy of four or six bits the design of such converters is straightforward. Higher accuracy requires careful consideration of numerous design constraints including critical current uncertainty, power supply regulation, turn-on-delay, signal line crosstalk, and the threshold curve critical points. The implications of these constraints are analyzed with respect to an example design for an 8-bit converter.
Radar-based intruder detection for a robotic security system (1999)

The Mobile Detection Assessment and Response System, Exterior (MDARS-E) provides an automated robotic security capability for storage yards, petroleum tank farms, rail yards, and arsenals. The system includes multiple supervised-autonomous platforms with intrusion detection, barrier assessment, and inventory assessment subsystems commanded from an integrated control station.
Analysis of the human serological response to proteins of Chlamydia trachomatis (1982)

Sera from individuals with culture-proven genital infection with Chlamydia trachomatis were analyzed for the presence of antibodies to chlamydial proteins by an immunoelectrophoretic transfer method. Protein antigens from representative strains of the 15 known serotypes were resolved by gel electrophoresis and transferred to a nitrocellulose solid support before being probed with serum. Sera from infected patients reacted with many different proteins. Most of these sera reacted with a 60,000- and a 62,000-molecular-weight protein which were present in each of the C. trachomatis serotypes and clinical isolates analyzed. In contrast, reactions with the major outer membrane protein were frequently observed but were usually weak. Sera from control groups of children, cloistered nuns, and college women, who were presumed not to have had prior chlamydial infections, did not usually have antibodies against the 60,000- or 62,000-molecular-weight protein, but did react with the major outer membrane protein and a 29,000-molecular-weight protein. These observations may have implications for the development of serodiagnostic tests as well as the identification of candidate antigens for vaccine development.
Recurrent Laryngeal Nerve Section for Spastic Dysphonia (1976)

Spastic dysphonia is a severe vocal disability in which a person speaks with excessively adducted vocal cords. The resulting weak phonation sounds tight, as if he were being strangled, and has also been described as laryngeal stutter. It is often accompanied by face and neck grimaces. In the past it has been regarded as psychoneurotic in origin and treated with speech therapy and psychotherapy with disappointing results. Because of laboratory and clinical observation that recurrent nerve paralysis retracts the involved vocal cord from the midline, it was proposed that deliberate section of the recurrent nerve would improve the vocal quality of patients with spastic dysphonia. In 34 patients the recurrent nerve was sectioned after Xylocaine® temporary paralysis showed significant improvement in vocal quality. Several patients have been advised against this operation because of the type of voice they developed with one vocal cord temporarily paralyzed. With nerve section plus postoperative speech therapy, approximately half of the patients have returned close to a “normal” but soft phonatory voice. The rest had varying degrees of improvement, but all, so far, have been pleased with the improvement in ease and quality of phonation and reduction or elimination of face and neck grimaces. Two men have a breathy component in their phonatory voices, and one woman has variable pitch.
Designing multichannel sensor arrays for biomagnetism (1992)

The design of large multichannel magnetometer systems for clinical applications have to be optimized carefully — in order to obtain an instrument which is capable to collect simultaneously all of the information needed for the measurement of transient pathological phenomena. Criteria for this optimization, such as spatial sampling frequency, sensor design and dimension of the array are discussed, utilising a novel quality factor, the equivalent source noise.
Investigation of the photoelectric conversion of a novel molecule (E)-N -methyl-4-{2-[4-(dihexadecylamino)phenyl]ethenyl}pyridazinium iodide, in LB films fabricated on an SnO2 electrode (1997)

An investigation of cathodic photocurrent response from a novel molecule with strong non-linear optical properties (second harmonic generation), (E)-N -methyl-4-{2-[4-(dihexadecylamino)phenyl]ethenyl}pyridazinium iodide (MHPd) in LB films on transparent SnO 2 glass has been carried out. A quantum yield of 0.3% was obtained under irradiation with 450 nm light in 0.5 mol dm -3 KCl electrolyte solution and ambient conditions. The studies of the relationship between the light intensity and the cathodic photocurrent indicate that MHPd assemblies perform a unimolecular process in charge recombination. The effects of bias voltage, oxygen and nitrogen, electron donors and acceptors such as methyl viologen diiodide, ascorbic acid and hydroquinone were examined and have provided supporting evidence for the proposed electron-transfer mechanism.
Increased Expression of Sodium Channel Subunit Nav1.1 in the Injured Dorsal Root Ganglion After Peripheral Nerve Injury (2011)

The mechanisms underlying neuropathic pain induction are very complex but might involve abnormal spontaneous activity in the sensory dorsal root ganglion (DRG). Voltage-gated sodium channels in the DRG are essential for the genesis of abnormal spontaneous neuronal activity. In this study, we examined the changes in expression of the voltage-gated sodium channel Nav1.1 in the DRG after peripheral nerve injury. Western blot analysis showed that the level of Nav1.1 protein in the ipsilateral L5 DRG was significantly increased on Days 3 and 7 after fifth lumbar spinal nerve ligation. Immunohistochemical study further confirmed a marked increase in the percentage of Nav1.1-positive cells in the ipsilateral DRG on Day 3 after fifth lumbar spinal nerve ligation. Similarly, on Day 7 after sciatic nerve axotomy, the amount of Nav1.1 protein and the percentage of Nav1.1-positive cells in the ipsilateral L5 DRG were also significantly increased. Our results suggest that an early increase in DRG Nav1.1 expression after peripheral nerve injury might be involved in the induction of neuropathic pain.

<i>N</i>-th order Ergodic Multigram HMM for modeling of languages without marked word boundaries (1996)

Ergodic HMMs have been successfully used for modeling sentence production. However for some oriental languages such as Chinese, a word can consist of multiple characters without word boundary markers between adjacent words in a sentence. This makes word-segmentation on the training and testing data necessary before ergodic HMM can be applied as the language model. This paper introduces the N-th order Ergodic Multigram HMM for language modeling of such languages. Each state of the HMM can generate a variable number of characters corresponding to one word. The model can be trained without word-segmented and tagged corpus, and both segmentation and tagging are trained in one single model. Results on its application on a Chinese corpus are reported.
Diffractive Laser Encoder with a Grating in Littrow Configuration (2008)

In this work, we present a new compact diffractive laser encoder system, which serves as a positional detection apparatus in precision machine applications. The encoder records displacement information in terms of grating period using the Doppler effect. Using the Littrow configuration, the novel encoder provides high alignment tolerances. The design is special such that a change in the gap between the grating and the optical head does not affect the measurements. Therefore, a Michelson interferometer can be added to the system to measure the out-of-plane displacement. This system will be developed as a three-dimensional displacement sensor in the future. Within a measurement distance of 100 µm, even in the laboratory environment, the maximum error is 53 nm and the repeatability is within ±20 nm.

Epidural haematoma by Mayfield head-holder®. Case report and review of literature. (2013)

A lot of neurosurgical interventions require the use of a pin-type head-holder to immobilize the patients&#039; head. We report the case of an epidural haematoma caused by penetration of head holders&#039; pin in a 7-year-old boy. The haematoma was showed by a head CT-scan at the end of surgery performed to treat a cerebellar astrocytoma that was managed surgically. Mmany factors seem to contribute to elevate the risk of complications due to the use of the Mayfield head-holder. Prevention and management measures are discussed also through a review of literature.
Large-Scale Comparative Genomic Analyses of Cytoplasmic Membrane Transport Systems in Prokaryotes (2007)

The recent advancements in genome sequencing make it possible for the comparative analyses of essential cellular processes like transport in organisms across the three domains of life. Membrane transporters play crucial roles in fundamental cellular processes and functions in prokaryotic systems. Between 3 and 16% of open reading frames in prokaryotic genomes were predicted to encode membrane transport proteins, emphasizing the importance of transporters in their lifestyles. Hierarchical clustering of phylogenetic profiles of transporter families, which are derived from the presence or absence of a certain transporter family, showed distinct clustering patterns for obligate intracellular organisms, plant/soil-associated microbes and autotrophs. Obligate intracellular organisms possess the fewest types and number of transporters presumably due to their relatively stable living environment, while plant/soil-associated organisms generally encode the largest variety and number of transporters. A group of autotrophs are clustered together largely due to their absence of transporters for carbohydrate and organic nutrients and the presence of transporters for inorganic nutrients. Inside of each group, organisms are further clustered by their phylogenetic properties. These findings strongly suggest the correlation of transporter profiles to both evolutionary history and the overall physiology and lifestyles of the organisms.
Mitochondrial matrix localization of a protein altered in mutants resistant to the microtubule inhibitor podophyllotoxin. (1987)

Specific antibodies to a protein designated P1 (Mr approximately equal to 63,000), which is specifically altered in mutants resistant to the microtubule inhibitor podophyllotoxin, bind to mitochondria in cells of various vertebrate and invertebrate species (Eur. J. Cell Biol. 44, 278-285 (1987); Can. J. Biochem. Cell Biol. 63, 489-502 (1985)). To investigate the relationship of this protein to mitochondria, rat liver mitochondria have been purified and immunoblot analysis with these provide evidence that the P1 protein is a major component of mitochondria. Two-dimensional gel electrophoretic analysis of mitochondrial proteins from Chinese hamster ovary (CHO) cells also show the P1 protein to be a major mitochondrial component. Subfractionation of rat liver mitochondria into various compartments indicates that the P1 protein is mainly associated with the matrix fraction. Effect of treatment of CHO cells with mitochondrial inhibitors on the synthesis of P1 protein was also investigated. Treatment with the K+ ionophores nonactin and valinomycin, which abolish mitochondrial membrane potential, inhibited synthesis of the mature forms of the P1 protein as well as a number of other mitochondrial proteins, as seen by two-dimensional gel electrophoresis of labeled polypeptides. Treatment of the podophyllotoxin-resistant mutant of CHO cells with the above inhibitors affected both the wild-type and the mutant forms of the P1 protein in a similar manner. Concomitant with the disappearance of the above proteins, new basic proteins of higher molecular masses, related to the P1 and other proteins by peptide analysis, were observed in the drug-treated cells.(ABSTRACT TRUNCATED AT 250 WORDS)
Citoquímica de la conjuntiva (1967)

Se ha mostrado de gran utilidad la tecnica usada por nosotros en la investigacion nuclear con extraccion del RNA en la que previa hidrolisis hemos tenido con el Pancromo de Gutierrez. Las extensiones con excelente tincion de contraste revelan los nucleos tenidos en azul-violeta-negro, dejando ver el DNA puntiforme y condensador alrededor de los nucleos que se presentan con toda nitidez al despolimerizarse el RNA. La investigacion de la actividad glucogenetica y fosfatasica por parte del citoplasma, se ha llevado a cabo por medio de la reaccion del PAS, segun Mc Manus y Hotchkis, y segun tecnica de Gutierrez-Montero, respectivamente. Las celulas epiteliales de la conjuntiva dan reaccion positiva al PAS en forma de granos finos concluyentes o en granos gruesos mas o menos aislados, habiendose observado una mayor actividad glucogenica en las de tipo cilindrico. Semejantes resultados obtenemos en las fosfatasas, cuya actividad se muestra mas intensa tambien en las de tipo cilindrico. La reaccion es de color pardo-negro y de distribucion hacia la periferia celular. La reaccion de las peroxidasas y los lipidos, segun tecnicas de Gutierrez y Lison, se ha mostrado constantemente negativa en las celulas epiteliales, conservando, no obstante, esta actividad las celulas sanguineas infiltradas. Con estos trabajos nos hemos asomado a la citoquimica de la conjuntiva, sentando las bases para estudios futuros, como serian, por ejemplo, investigacion de la estructura del DNA y los nucleolos, la actividad fosfatasica alcalina, la naturaleza de la reaccion del PAS, etcetera.
Effects of propellant and electrode geometry on pulsed ablative plasma thruster performance (1975)

A performance level compatible with 30% thrust efficiency at 1500 s specific impulse at 1 mlb (4.45 mN) of thrust was demonstrated with the parallel rail pulsed ablative thruster using Teflon propellant. Parametric variations of interelectrod e spacing and included angle were performed. In addition, Teflon was replaced by other thermoplastics and was also seeded with 10% and 30% LiOH and InBr in an evaluation of alternative propellants. Both the conventional breech-fed and later side-feed electrode/propellant configurations were tested. With the same initial conditions it was shown that the breech-fed geometry yields higher thrust efficiency than the side-fed geometry because of the higher specific impulse generated (i.e., up to 5300 s using Teflon). Results of parametric studies indicate that, for high thrust/power and moderately high specific impulse, virgin Teflon propellant with an interelectrode spacing of 3.0 in. (7.62 cm) and zero degree interelectrode included angle in the side-fed configuration are best. A simple semiempirical analytic model is presented where it is shown that the broad range in performance characteristic of this device is related to the degree to which magnetoplasmadynamic and ordinary gasdynamic acceleration mechanisms can be made more or less dominant in the acceleration of the ablated propellant.

Large-Scale Assessment of the Zebrafish Embryo as a Possible Predictive Model in Toxicity Testing (2011)

For the substances examined here, in aggregate, the zebrafish embryo model has good predictivity for toxicity in rodents. However, the correlation between zebrafish and rodent toxicity varies considerably between individual compounds and compound class. We discuss the strengths and limitations of the zebrafish model in light of these findings.
Changes in extracellular and intracellular pH in ischemic rabbit papillary muscle. (1992)

The extracellular pH (pHo) and intracellular pH (pHi) were simultaneously measured with H(+)-sensitive microelectrodes in the rabbit papillary muscle during normal arterial perfusion and no-flow ischemia. The preparation was kept in an artificial gaseous atmosphere (N2 and CO2 during ischemia) without a surrounding fluid layer. Cylindrical muscles of small diameters (less than 1.0 mm) were selected to prevent major diffusion gradients of CO2 within the muscle cylinder during ischemia. In normal perfusion with CO2/HCO3(-)-buffered blood at PCO2 of 35 mm Hg, pHi was 7.03 +/- 0.03. During early ischemia, extracellular acidification was much more prominent than intracellular acidification. Consequently, the transmembrane pH gradient reversed (pHo less than pHi) at approximately 8 minutes. At 14 minutes of ischemia, pHo was 6.64 and pHi was 6.93. A moderate increase in PCO2 from 35 to 67 mm Hg before ischemia enhanced intracellular acidification in ischemia. Simulation of CO2 accumulation (increase of PCO2 in the surrounding atmosphere), as encountered in midmural ventricular layers during in vivo ischemia, produced a significant decrease of pHo (6.30 versus 6.64) and pHi (6.65 versus 6.93) at 14 minutes of ischemia. The presence of red blood cells in the intravascular space after arrest of coronary perfusion showed a pronounced effect on extracellular and intracellular acidosis. If the muscles were perfused with CO2/HCO3(-)-buffered perfusate in the absence of red blood cells, the changes of pHo and pHi were significantly larger (pHo, 6.00 versus 6.64; pHi, 6.46 versus 6.93 at 14 minutes) during ischemia. Actively developed force during ischemia was not significantly influenced by conditions modulating pHi. It decreased by 82% after 5 minutes, even when no significant change of pHi was recorded. By contrast, ischemic contracture was dependent on intracellular acidification. It developed earlier in the absence of red blood cells or with low extracellular buffer capacity. It is concluded that during acute myocardial ischemia 1) extracellular acidification exceeds intracellular acidification, 2) the decrease in pHi is inhomogeneous because of local variation in CO2 accumulation and diffusion, 3) the decrease in pHi is relatively small in the presence of red blood cells, and 4) the development of ischemic contracture but not the early decline in active tension is sensitive to changes in pHi.
Simulation research on the return conductor configuration of aircraft lightning indirect effect test (2016)

The aircraft indirect effect test method was studied in this paper based on the numerical simulation method. Meanwhile the influence of the return conductor arrangement on the load matching and current distribution was also analyzed. The aircraft lightning test system models with coaxial return path were established, and their distribution parameters and the characteristic impedances were calculated. The current resonant under different load impedance was analyzed using one dimensional FDTD (finite-difference time-domain) algorithm. On this basis, the current density distributions on the surface of the fuselage with different return conductor arrangements were calculated by the simulation software CST. The conclusions provide foundation for the further research on the return conductor configuration of fixed wing aircraft lightning test.
