[Adrenergic innervation of the middle and internal ear in man]. (2000)

Adrenergic nervous structures (ANS) in morphofunctional formations of human middle and internal ear were studied on the autopsy material obtained from 5 victims of accidents free of any ear disease. The samples were treated histochemically with glyoxylic acid. Non-varicose dilated sympathetic nerve fibers (single and in bundles, non-myelinized, intensively luminescent, twisted and direct) were detected in vertical nerve sections, in spiral and vestibular ganglia, in chorda tympani. A thick net of adrenergic nerve fibers (ANF) was noted around the labyrinthine artery. ANF were absent long along the walls of the utriculus and semicircular canals, in the modiolus vessels, spiral ligament, vascular stripe. ANF were most numerous on the osseous spiral lamina. Near the Corti's organ ANF are thicker and often varicose. On the vertical sections of m. stapedius ANF with varicose parts locate in the connective tissue perimysial layers and in the endomysium directly between the muscular cells. At the site of muscle transition into the tendon and in tendon as such no ANF were found. Two sets of ANF were noted in the middle ear mucosa: perivascular and unrelated to blood vessels.
MMIC family for DBS downconverter with pulse-doped GaAs MESFETs (2002)

An MMIC (monolithic microwave integrated circuit) family was demonstrated for a low noise block downconverter (LNB) for use in direct broadcast satellite (DBS) receivers operating from 11.7 to 12 GHz. A 12 GHz low noise amplifier, a 12 GHz mixer, a 10.7 GHz dielectric resonator oscillator and a 1 GHz IF amplifier were designed with 05 mu m-gate pulse-doped GaAs MESFETs. Noise-free pictured of satellite broadcast TV could be seen by using this LNB and a parabolic antenna forty centimeters in diameter.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
140-km 20-Gbit/s repeaterless transmission employing distributed erbium amplification (1992)

Current research efforts in the fields of optical transmission are aimed at identifying how optical processing may be beneficial in the implementation of large scale networks. A prerequisite for such developments is the attainment of the largest possible unrepeatered span of individual links in the network. In this paper, we show how the maximum unrepeatered span of a 20-Gbit/s system (4 × 5-Gbit/s optical time-division multiplexed) may be enhanced by using a length of transmission fiber which has been lightly (50 ppb) doped with erbium ions to provide distributed preamplification at the receiver. The optical pump power for the distributed amplifier is provided from the terminal end only, resulting in true repeaterless operation.
EARLY INFECTIONS IN KIDNEY, HEART, AND LIVER TRANSPLANT RECIPIENTS ON CYCLOSPORINE (1983)

Eighty-one renal, seventeen heart, and twenty-four liver transplant patients were followed for infection. Seventeen renal patients received azathioprine (Aza) and prednisone as part of a randomized trial of immunosuppression with 21 cyclosporine-and-prednisone-treated renal transplant patients. All others received cyclosporine and prednisone. The randomized Aza patients had more overall infections (P less than 0.05) and more nonviral infections (P less than 0.02) than the randomized cyclosporine patients. Heart and liver patients had more infections than cyclosporine renal patients but fewer infections than the Aza renal patients. There were no infectious deaths in renal transplant patients on cyclosporine or Aza, but infection played a major role in 3 out of 6 cardiac transplant deaths and in 8 out of 9 liver transplant deaths. Renal patients on cyclosporine had the fewest bacteremias. Analysis of site of infection showed a preponderance of abdominal infections in liver patients, intrathoracic infections in heart patients, and urinary tract infections in renal patients. Pulmonary infections were less common in cyclosporine-treated renal patients than in Aza-treated patients (P less than 0.05). Aza patients had significantly more staphylococcal infections than all other transplant groups (P less than 0.005), and systemic fungal infections occurred only in the liver transplant group. Cytomegalovirus (CMV) shedding or serological rises in antibody titer, or both occurred in 78% of cyclosporine patients and 76% of Aza patients. Of the cyclosporine patients, 15% had symptoms related to CMV infection. Serological evidence for Epstein Barr Virus infection was found in 20% of 65 cyclosporine patients studied. Three had associated symptoms, and one developed a lymphoma.
On the Analysis and Design of Spurline Bandstop Filters (1985)

The parameters of general two-coupled lines and symmetric three-coupled lines in an inhomogeneous medium for the lossless case are obtained. The impedance and chain matrices of spurline bandstop filters are derived. One-section spurline bandstop filters with their stopbands centered near 33 GHz have been designed and tested. There is excellent agreement between the experimental results and those predicted theoretically.
The evaluation of buried-channel layer in BCCD's (1978)

A simple method of evaluating buried-channel layers in BCCD's, using current-voltage measurement, is presented. This method is based on the assumption of uniform layer doping and depletion approximation. The validity of this evaluation method is demonstrated by agreement between calculated and experimental results.
Protection against Lethal Vaccinia Virus Challenge in HLA-A2 Transgenic Mice by Immunization with a Single CD8<sup>+</sup>T-Cell Peptide Epitope of Vaccinia and Variola Viruses (2004)

CD8(+) T lymphocytes have been shown to be involved in controlling poxvirus infection, but no protective cytotoxic T-lymphocyte (CTL) epitopes are defined for variola virus, the causative agent of smallpox, or for vaccinia virus. Of several peptides in vaccinia virus predicted to bind HLA-A2.1, three, VETFsm(498-506), A26L(6-14), and HRP2(74-82), were found to bind HLA-A2.1. Splenocytes from HLA-A2.1 transgenic mice immunized with vaccinia virus responded only to HRP2(74-82) at 1 week and to all three epitopes by ex vivo enzyme-linked immunosorbent spot (ELISPOT) assay at 4 weeks postimmunization. To determine if these epitopes could elicit a protective CD8(+) T-cell response, we challenged peptide-immunized HLA-A2.1 transgenic mice intranasally with a lethal dose of the WR strain of vaccinia virus. HRP2(74-82) peptide-immunized mice recovered from infection, while naïve mice died. Depletion of CD8(+) T cells eliminated protection. Protection of HHD-2 mice, lacking mouse class I major histocompatibility complex molecules, implicates CTLs restricted by human HLA-A2.1 as mediators of protection. These results suggest that HRP2(74-82), which is shared between vaccinia and variola viruses, may be a CD8(+) T-cell epitope of vaccinia virus that will provide cross-protection against smallpox in HLA-A2.1-positive individuals, representing almost half the population.

Organization and Ca<sup>2+</sup>Regulation of Adenylyl Cyclases in cAMP Microdomains (2007)

The adenylyl cyclases are variously regulated by G protein subunits, a number of serine/threonine and tyrosine protein kinases, and Ca(2+). In some physiological situations, this regulation can be readily incorporated into a hormonal cascade, controlling processes such as cardiac contractility or neurotransmitter release. However, the significance of some modes of regulation is obscure and is likely only to be apparent in explicit cellular contexts (or stages of the cell cycle). The regulation of many of the ACs by the ubiquitous second messenger Ca(2+) provides an overarching mechanism for integrating the activities of these two major signaling systems. Elaborate devices have been evolved to ensure that this interaction occurs, to guarantee the fidelity of the interaction, and to insulate the microenvironment in which it occurs. Subcellular targeting, as well as a variety of scaffolding devices, is used to promote interaction of the ACs with specific signaling proteins and regulatory factors to generate privileged domains for cAMP signaling. A direct consequence of this organization is that cAMP will exhibit distinct kinetics in discrete cellular domains. A variety of means are now available to study cAMP in these domains and to dissect their components in real time in live cells. These topics are explored within the present review.
Regeneration of the Hop Plant (<i>Humulus Lupulus</i>L.) From Softwood Cuttings. I. the Cutting and Its Rooting Environment (1965)

AbstractSoftwood cuttings of the hop plant root readily in mist culture. A few preformed roots are present in the more mature parts of the stem and new roots are initiated within three days of taking the cutting. The success obtained with leafy softwood cuttings is probably associated with their ability to accumulate carbohydrates during the rooting period, since the effect of reducing the leaf area of the cutting, or reducing the light intensity, is to depress rooting.The cuttings under mist received a high level of light intensity without a concomitant large increase in ambient temperature such as occurred in a closed propagating case, where the necessity to shade the cuttings to prevent them from wilting resulted in a low light intensity and relatively high ambient temperature, which adversely affected rooting.The level of bottom heat was found to have a marked influence on regeneration.
Three-Dimensional Hierarchical Porous Structure of PPy/Porous-Graphene to Encapsulate Polysulfides for Lithium/Sulfur Batteries (2018)

Herein, we demonstrate the fabrication of a three-dimensional (3D) polypyrrole-coated-porous graphene (PPy/PG) composite through in-situ polymerization of pyrrole monomer on PG surface. The PPy/PG displays a 3D hierarchical porous structure and the resulting PPy/PG hybrid serves as a conductive trap to lithium polysulfides enhancing the electrochemical performances. Owing to the superior conductivity and peculiar structure, a high initial discharge capacity of 1020 mAh g−1 and the reversible capacity of 802 mAh g−1 over 200 cycles are obtained for the S/PPy/PG cathode at 0.1 C, remaining the remarkable cyclic stability. In addition, the S/PPy/PG cathodes demonstrate an excellent rate performance exhibiting 477 mAh g−1 at 2 C.
Essential feature extraction of driving behavior using a deep learning method (2015)

Driving behavior can be represented by many different types of measured sensor information obtained through a control area network. We assume that the measured sensor information is generated from several hidden time-series data through multiple nonlinear transformations. These hidden time-series data are statistically independent of each other and capture essential driving behavior. Driving behavior information is usually generated by multiple nonlinear transformations that fuse essential features, e.g., "Yaw rate" is generated by fusing the velocity of the vehicle and the change of driving direction. However, driving behavior data is often redundant because such data includes multivariate information and involves duplicated essential features. In this paper, we propose a feature extraction method to extract essential features from redundant driving behavior data using a deep sparse autoencoder (DSAE), which is a deep learning method. Two-dimensional features are extracted from seven-dimensional artificial data using a DSAE and are determined experimentally to be highly correlated with the prepared essential features. DSAEs are also used to extract features from an actual driving behavior data set. To verify a DSAE's ability to extract essential driving behavior features and filter out redundant information, we prepare twelve data sets that include some or all of the driving behavior information. Twelve DSAEs are used to independently extract features from the twelve prepared data sets, and canonical correlation analysis is used to analyze the canonical correlation coefficients between extracted features. Furthermore, we verify DSAEs' ability to extract essential driving behavior features from the redundant driving behavior data sets.
Discretionary caching for I/O on clusters (2003)

I/O bottlenecks are already a problem in many largescale applications that manipulate huge datasets. This problem is expected to get worse as applications get larger, and the I/O subsystem performance lags behind processor and memory speed improvements. Caching I/O blocks is one effective way of alleviating disk latencies, and there can be multiple levels of caching on a cluster of workstations. Previous studies have shown the benefits of caching whether it be local to a particular node, or a shared global cache across the cluster - for certain applications. However, we show that while caching is useful in some situations, it can hurt performance if we are not careful about what to cache and when to bypass the cache. This paper presents compilation techniques and runtime support to address this problem. These techniques are implemented and evaluated on an experimental Linux/Pentium cluster running a parallel file system. Our results using a diverse set of applications (scientific and commercial) demonstrate the benefits of a discretionary approach to caching for I/O subsystems on clusters, providing as much as 33% savings over indiscriminately caching everything in some applications.
Potential uses of rapidly solidified alloys in gas turbine engines (1980)

The benefit of rapid solidification was studied relative to the development of new superalloy compositions for appcation in the hot sections of the gas turbine. Centrifugal atomization ofliquid metal into powder droplets and subsequent freezing by forced convective cooling was used to produce experimental alloys in a rapidly solidified form. Metalworking techniques common to powder-metallurgy processing were used, in turn, to produce bulk stock for test and evaluation. Results with the precipitation-hardening class of superalloys showed that higher concentrations of alloying additions than possible with conventional solidification practices could be achieved by rapid solidification without onset of macrosegregation or deleterious solidification compoundformation. It was found also that certain groups of alloys within this class responded effectively to abnormal grain growth which was controllable to produce aligned crystallographic structures. These combined characteristics were used to develop an alloy composition based on the nickel-aluminium-molybdenum ternary which showed a significant improvement in high-temperature creep resistance over currently available superalloys. Data interpretation suggested that the creep improvement was of the order of 55K.
Sympathetic Activation in Heart Failure and Its Treatment With β-Blockade (1999)

Multiple models explaining the pathogenesis of heart failure have been put forth during the past 5 decades. These models were modified as clinical evidence supported or refuted their assumptions. During the past 2 decades, heart failure models emphasized the importance of neurohormonal systems in heart failure progression. The positive impact that angiotensin-converting enzyme inhibitors have had on mortality from heart failure has bolstered the neurohormonal theory. Attention recently has turned to the sympathetic nervous system and its potential deleterious effects on the cardiovascular system in heart failure. The sympathetic nervous system can negatively impact the cardiovascular system in heart failure in several ways, including down-regulating beta1-receptors, exerting direct toxic effects on the myocardium, and contributing to myocardial remodeling and life-threatening arrhythmias. Beta-adrenergic blockers have shown promise for reducing morbidity and mortality in heart failure, but definitive reductions in mortality remain to be shown by future investigations.

Synthesis and antibacterial evaluation of 1,2,3,4-tetrahydro-4-oxo-1,8-naphthyridine-3-carboxylic acid esters, carbonitriles, and carboxamides (1975)

A series of 1,2,3,4-tetrahydro-4-oxo-1,8-naphthyridine-3-carboxylic acid esters, carbonitriles, and carboxamides (2a-k) was synthesized and initially evaluated (dose range 50-400 mg/kg) in mice infected with Escherichia coli. Only two derivatives, the ethyl and butyl esters of 1-ethyl-1,2-dihydro-4-hydroxy-7-methyl-1,8-naphthyridine-3-carboxylic acid, protected the animals against E. coli and several other gram-negative bacterial pathogenic infections. A pro-drug type of mechanism appears to be operable since neither agent showed in vitro activity.
Optimal routing and scheduling for deterministic delay tolerant networks (2009)

Delay Tolerant Networks (DTNs), in which contacts between nodes come and go over time, is a promising approach to model communications in mobile ad-hoc networks, where scenarios of network partitioning and node disconnections are likely to happen. One of the most important challenges in such networks is how to route information and schedule transmissions, coping with the continuously changing network topology.In this paper, we focus on a deterministic and centralized DTN in which the contact times between nodes are known in advance or can be predicted; this model is applicable for various real-life scenarios. We provide a general framework for devising optimal routing algorithms to such networks under different objective functions and various real-life constraints (such as the available buffer and energy). The key insight is to model the DTN as an equivalent time-independent graph; this allows the usage of well-known algorithms and techniques to achieve optimal results. These algorithms can be also used as approximation for less certain settings or as benchmarks to evaluate other routing algorithms. In addition, we extended our framework to deal with long-lived DTNs in which contacts are periodic. Our algorithms are demonstrated by simulations, based directly on real-life traces, showing capacity-delay tradeoffs and the influence of the constraints and periodicity on the achievable throughput of the network.
Vessel size imaging in humans (2005)

The relation of contrast-enhanced transverse relaxation rates R2* and R2 provides in vivo mapping of the mean caliber of cerebral vessels. This technique is referred to as vessel size imaging (VSI). Here a quantitative assessment of the vessel caliber in brain tumor patients is presented. The obtained mean vessel size shows sensitivity to the tumor type. A theoretical analysis is given to elucidate the morphological information content of VSI in the context of vessel architecture. The simplification of the theory underlying the data processing results in a systematic overestimation of the vessel caliber. An increase in the magnetic susceptibility of the contrast agent allows for quantitatively more accurate measurements. Quantitative VSI must include measurements of the regional diffusion coefficient and absolute determination of the regional cerebral blood volume.

Synthesis and oral hypoglycemic properties of two 4-oxo-4,5,6,7-tetrahydroindole-3-acetic acids. (1989)

Condensation of beta-acetyl-2-hydroxy-4,4-dimethyl-6-oxo-1-cyclohexene-1-propionic acid (3) with n-butyl and isobutylamines affords the title acids 4 and 5, respectively, which show good oral hypoglycemic activity in normal rats. Acids 4 and 5, are also active in streptozocin-induced diabetic rats. Results of extensive pharmacological and acute toxicity tests are reported.
Enhanced millimeter wave transmission through quasioptical subwavelength perforated plates (2005)

In this paper, we show that the phenomenon of extraordinary transmission through arrays of subwavelength holes, present in the optical regime, is also present in the millimeter wave range. After presentation of the theoretical foundations of the enhanced transmission, measurements of the transmission response have been performed on different samples by using a millimeter wave quasioptical vector network analyzer in the range between 45 and 110 GHz. The prototypes have been fabricated in Aluminum plates with several thickness and different hole diameters drilled by using a laser machine. Good agreement between theory and experiment is obtained, with clear signals of the existence of resonant transmission at wavelengths close to the period of the array. Possible applications in frequency selective surfaces and near-field imaging are envisaged.
