Cylindrical microlasers and light emitting devices from conducting polymers (1998)

Substantially improved, photopumped polymer lasers are demonstrated using microrings and microdisks of various diameters D ranging from 5 to 200 μm. Various cavity-dependent laser modes were observed, which for D&lt;10 μm were dominated by a single longitudinal mode with linewidth of less than 1 Å. These microlasers were also characterized by Q of order 5000, low threshold excitation energy of order 100 pJ/pulse for pulse duration ranging from 100 ps to sub-μs, and an abrupt increase in the emission directionality and polarization degree. Light emitting diodes with cylindrical geometry, fully compatible with these microlasers are also demonstrated.
Human Monocyte-derived Multinucleated Giant Cells (2004)

Multinucleated giant cells (MGC) are characteristic cells in granulomatous disorders such as sarcoidosis and leprosy. There are two types of MGC; foreign body-type and Langhans-type cells. The exact mechanisms of the formation and the functional significance of MGC are not determined, although their morphological features are well understood. MGC are also formed in vitro from peripheral blood mononuclear cells by stimulation with cytokines and lectins. Particularly IFN-gamma is considered to play a pivotal role in monocyte fusion. IL-3, IL-4, IL-13, and GM-CSF are other reported cytokines involved in MGC formation. In addition to such inflammatory mediators, a factor derived from the pathogens of granulomatous disorders may be necessary for MGC formation. Muramyl dipeptide, a peptidoglycan portion of bacterial cell walls, is one of the candidates and can preferentially induce Langhans-type cells in in vitro MGC formation system. Although the exact mechanisms of in vitro MGC formation remains unknown, cell surface molecules such as P2X7 receptor, integrins, CD98, and macrophage fusion protein are considered to be involved in fusion process. Monocytes of sarcoidosis patients expressed higher levels of P2X7 and had a higher ability to induce MGC than those of healthy controls. Effective agents for sarcoidosis such as tranilast, alloprinol, and captopril inhibited in vitro MGC formation, suggesting their therapeutic effects through the direct effects on monocytes. Thus, an in vitro MGC formation model would be a useful tool to understand the relevance of MGC in granulomatous disorders.
Clinical Applications of Blood-Derived and Marrow-Derived Stem Cells for Nonmalignant Diseases (2008)

Stem cells harvested from blood or marrow, whether administered as purified HSCs or mesenchymal stem cells or as an unmanipulated or unpurified product can, under appropriate conditions in select patients, provide disease-ameliorating effects in some autoimmune diseases and cardiovascular disorders. Clinical trials are needed to determine the most appropriate cell type, dose, method, timing of delivery, and adverse effects of adult HSCs for these and other nonmalignant disorders.
High voltage ride-through of DFIG-based wind turbines (2008)

With the rapid increase of large offshore wind farms in Europe, a new problem associated with the response of wind turbines to temporary overvoltages has arisen. This problem has not been a focus of discussion up to now. The majority of wind turbines use voltage source converters with a DC-link. When the grid voltage exceeds a certain limit the current flow through the line-side converter may reverse, resulting in a rapidly increasing DC voltage. To handle such situations, special countermeasures are required. This paper identifies and outlines the problem and recommends possible measures to ride through the overvoltage safely. Additionally, active voltage control structures to limit the overvoltages are proposed.

Image Velocity Sensing by Optical Correlation (1966)

The technique of measuring the velocity of a moving image by means of a parallel-slit spatial filter is treated as continuous optical correlation processing. This technique is compared with other approaches to measuring image velocity by correlation and is shown to be a special case where the image displacement necessary for the correlation measurement is held constant and the time interval required to traverse this fixed distance is measured. The time measurement is accomplished inherently in terms of the frequency of the periodic signal generated by the image motion. Based on a derived mathematical model of the process and the characteristics of spatial filters, some conclusions are drawn about the way various parameters affect signal quality and continuity.
Keratinocyte growth factor accelerates wound closure in airway epithelium during cyclic mechanical strain (1999)

The airway epithelium may be damaged by inhalation of noxious agents, in response to pathogens, or during endotracheal intubation and mechanical ventilation. Maintenance of an intact epithelium is important for lung fluid balance, and the loss of epithelium may stimulate inflammatory responses. Epithelial repair in the airways following injury must occur on a substrate that undergoes cyclic elongation and compression during respiration. We have previously shown that cyclic mechanical strain inhibits wound closure in the airway epithelium (Savla and Waters, 1998b). In this study, we investigated the stimulation of epithelial wound closure by keratinocyte growth factor (KGF) in vitro and the mechanisms by which KGF overcomes the inhibition due to mechanical strain. Primary cultures of normal human bronchial epithelial cells (NHBE) and a cell line of human airway epithelial cells, Calu 3, were grown on Silastic membranes, and a wound was scraped across the well. The wells were then exposed to cyclic strain using the Flexercell Strain Unit, and wound closure was measured. While cyclic elongation (20% maximum) and cyclic compression (approximately 2%) both inhibited wound closure in untreated wells, treatment with KGF (50 ng/ml) significantly accelerated wound closure and overcame the inhibition due to cyclic strain. Since wound closure involves cell spreading, migration, and proliferation, we investigated the effect of cyclic strain on cell area, cell-cell distance, and cell velocity at the wound edge. While the cell area increased in unstretched monolayers, the cell area of monolayers in compressed regions decreased significantly. Treatment with KGF increased the cell area in both cyclically elongated and compressed cells. Also, when cells were treated with KGF, cell velocity was significantly increased in both static and cyclically strained monolayers, and cyclic strain did not inhibit cell migration. These results suggest that KGF is an important factor in epithelial repair that is capable of overcoming the inhibition of repair due to physiological levels of cyclic strain.

Impaired skeletal muscle development and function in male, but not female, genomic <i>androgen receptor</i> knockout mice (2008)

To identify mechanisms of anabolic androgen action in muscle, we generated male and female genomic androgen receptor (AR) knockout (ARKO) mice, and characterized muscle mass, contractile function, and gene expression. Muscle mass is decreased in ARKO males, but normal in ARKO females. The levator ani muscle, which fails to develop in normal females, is also absent in ARKO males. Force production is decreased from fast-twitch ARKO male muscle, and slow-twitch muscle has increased fatigue resistance. Microarray analysis shows up-regulation of genes encoding slow-twitch muscle contractile proteins. Real-time PCR confirms that expression of genes encoding polyamine biosynthetic enzymes, ornithine decarboxylase (Odc1), and S-adenosylmethionine decarboxylase (Amd1), is reduced in ARKO muscle, suggesting androgens act through regulation of polyamine biosynthesis. Altered expression of regulators of myoblast progression from proliferation to terminal differentiation suggests androgens also promote muscle growth by maintaining myoblasts in the proliferate state and delaying differentiation (increased Cdkn1c and Igf2, decreased Itg1bp3). A similar pattern of gene expression is observed in orchidectomized male mice, during androgen withdrawal-dependent muscle atrophy. In conclusion, androgens are not required for peak muscle mass in females. In males, androgens act through the AR to regulate multiple gene pathways that control muscle mass, strength, and fatigue resistance.
A Critical Review of Alpha Radionuclide Therapy—How to Deal with Recoiling Daughters? (2015)

This review presents an overview of the successes and challenges currently faced in alpha radionuclide therapy. Alpha particles have an advantage in killing tumour cells as compared to beta or gamma radiation due to their short penetration depth and high linear energy transfer (LET). Touching briefly on the clinical successes of radionuclides emitting only one alpha particle, the main focus of this article lies on those alpha-emitting radionuclides with multiple alpha-emitting daughters in their decay chain. While having the advantage of longer half-lives, the recoiled daughters of radionuclides like 224Ra (radium), 223Ra, and 225Ac (actinium) can do significant damage to healthy tissue when not retained at the tumour site. Three different approaches to deal with this problem are discussed: encapsulation in a nano-carrier, fast uptake of the alpha emitting radionuclides in tumour cells, and local administration. Each approach has been shown to have its advantages and disadvantages, but when larger activities need to be used clinically, nano-carriers appear to be the most promising solution for reducing toxic effects, provided there is no accumulation in healthy tissue.
Effects of branching on some properties of ethylene/α‐olefin copolymers (1972)

Abstract Copolymers of ethylene with relatively small amount of nine species of α‐olefins, i.e. , propylene, butene‐1, pentene‐1, hexene‐1, octene‐1, dodecene‐1, octadecene‐1, 4‐methylpentene‐1, and 4.6‐dimethylheptene‐1 were prepared with the use of ZIEGLER‐NATTA catalyst and their melt properties, crystalline behaviors, and various physical properties were investigated in relation to the side‐chain length and structure. The melt index‐intrinsic viscosity (MI‐[η]) correlation, melt tension, and melt extensibility were found to be hardly affected by the branches. On the crystalline behavior and physical properties, the effects of branching generally became more pronounced when the branch sizes became larger. It was noticeable, however, that ethyl and propyl branches exert strong effects in comparison with their relatively small sizes. It was also observed that the ethylene/octadecene‐1 copolymers have lower β‐peak heights and higher β‐peak temperatures in E″‐temperature curves than expected from their branch size, and this was considered to be due to the crystallization of the side‐chains. The properties of high pressure polyethylenes coincided, in many respects, with those of the copolymers having bulky branches.
Direct Cyclic Carbonate Synthesis from CO<sub>2</sub> and Diol over Carboxylation/Hydration Cascade Catalyst of CeO<sub>2</sub> with 2-Cyanopyridine (2014)

We first achieved direct synthesis of propylene carbonate from CO2 and 1,2-propanediol in excellent yield (>99%) using a carboxylation/hydration cascade catalyst of CeO2 with 2-cyanopyridine. The catalyst system can be applied to syntheses of various cyclic carbonates, including 6-membered ring carbonates that are difficult to synthesize in high yields (62−>99%).
Growing Plants Without Soil (1970)

Growing plants without soil is not new. Man started agricultural pur-suits by growing plants in soil but as the knowledge of plant nutrition increased, he learned to grow plants in artificial media, such as quartz, sand, gravel, etc. The next step was to eliminate solid media and to grow plants directly in solutions. By 1860 the principles of growing plants in solution were well understood, and satisfactory solutions for supplying nutrients to plants were developed. It was not until 1929, however, that the commercial possibilities of this method were realized. The idea of growing plants in solution instantly became popular, and many articles about it appeared in popular media. Many exaggerated and wholly un-found claims were made for this method of growing plants. This interest has been maintained until this day. This circular is intended to supply information on growing plants without soil. Principles of Growing Plants Without Soil A knowledge of the principles of plant physiology and horticulture or agronomy involv~d in crop production is necessary for growing plants in the soil or without soil. By supplying nutrients and water to plants, only two of the physiological process of the plant are satisfied. The sig-nificance of other interrelated processes must be understood, especially photosynthesis, respiration, transpiration, and reproduction. In addition, when establishing an installation for growing without soils, many prob-lems of engineering and economics must be considered as well. 1
Statistical issues in the analysis of DNA Copy Number Variations (2008)

Approaches to assess copy number variation have advanced rapidly and are being incorporated into genetic studies. While the technology exists for CNV genotyping, a further understanding and discussion of how to use the CNV data for association analyses is warranted. We present the options available for processing and analysing CNV data. We break these steps down into choice of genotyping platform, normalisation of the array data, calling algorithm, and statistical analysis.
Characterization of phenolic compounds in <i>Erigeron breviscapus</i> by liquid chromatography coupled to electrospray ionization mass spectrometry (2007)

Erigeron breviscapus is an important herbal drug for the treatment of cardiovascular and cerebral vessel diseases. In this study, phenolic compounds were extracted from the whole plant of E. breviscapus and analyzed by high-performance liquid chromatography/electrospray ionization mass spectrometry. A total of 53 compounds were identified or tentatively characterized based on their UV and mass spectra. These compounds included caffeoylquinic acids (CQAs), CQA glucosides, malonyl-CQAs, acetyl-CQAs, caffeoyl-2,7-anhydro-3-deoxy-2-octulopyranosonic acids (CDOAs), caffeoyl-2,7-anhydro-2-octulopyranosonic acids (COAs), flavones, flavonols and flavonones. Most of them were reported for the first time from E. breviscapus and nineteen of them belonged to new compounds. The MS(n) spectra of CQA glucosides were similar to CQAs and they were discriminated by their retention times. No caffeic acid related ions (X(0) (-), Y(0) (-) and Z(0) (-)) were observed in MS(n) spectra of acyl-CQAs compared to those of CQAs. Fragment ions ((2,5)O(-), (3,6)O(-) and (4,6)O(-)) corresponding to ring cleavage were shown in MS(n) spectra of CDOAs and COAs, characteristic of this class of compounds. The 5,6,7-trihydroxyl-substituted flavones were dominant in E. breviscapus. Their [A--H](-) ions underwent the loss of a molecule of H(2)O, followed by the loss of CO, which was used to discriminate from other hydroxyl-substituted flavones. Our results are the first comprehensive analysis of E. breviscapus constituents and will be helpful for the quality control of the herb of E. breviscapus and its related preparations.
Polycrystalline silicon thin-film transistors on a novel 800°C glass substrate (1986)

A new polycrystalline silicon thin-film transistor (TFT) technology using a potentially low-cost glass substrate is reported. Transistors are made using modified conventional n-channel MOS processes at temperatures of 800°C or less, with a final hydrogen implantation step. These transistors show leakage currents of 2 × 10 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">-11</sup> A/µm of channel width, ON-to-OFF current ratios of 1 × 10 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">4</sup> at V <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">ds</inf> = 9.0 V, and good dc stability.

TWO POSSIBLE COSMIC X-RAY SPECTRAL LINES (1996)

A possible cosmic X-ray background(XRB) radiation related to original antimatter is considered. If the universe is made of separating domains of antimatter and matter, the photons produced by the annihilation of electronpositron and proton-antiproton on the last scattering surface would reach us in the energy ¸0.45 keV and ¸60 keV respectively because of the redshift. The spectrums of X-ray radiation from annihilation are deduced and a possible observational figure is described also. Key Words : X-ray background, Antimatter, Cosmology I. INTRODUCTION The X-ray background (XRB) radiation was first discovered by Giacconi et al. (Giacconi 1962). Since then, the whole band of XRB has been studied by means of HEAO-1,2 and ROSAT. The bulk of the energy density of the X-ray in the sky is dominated by a diffuse cosmic radiation caused by several models (Fabin 1992). In this paper we suggest that a part of XRB might be related to the original antimatter if a symmetric universe existed. A com...

Adaptive virtual topology reconfiguration policy employing multi-stage traffic prediction in optical Internet (2003)

This paper studies the issues arising in the virtual topology reconfiguration phase of optical Internet networks. This reconfiguration process means to change the virtual topology in response to the changing traffic patterns in the higher layer. We formulate the optimal reconfiguration policy as a multi-stage decision-making problem to maximize the expected reward and cost function over an infinite horizon. To counter the continual approximation problem brought by heuristic approach, we take the traffic prediction into consideration. We propose a new heuristic reconfiguration algorithm called prediction based multi-stage reconfiguration approach to realize the optimal reconfiguration policy. Simulation results show that our reconfiguration policy significantly outperforms the conventional one, while the required physical resources are limited.
A Stone Terminal from Cambodia (1933)

THERE HAS BEEN added to the permanent collection of the Toledo Museum of Art an architectural ornament labeled A Stone Terminal From Cambodia. It is a large, heavy piece of sandstone, carved in relief, which was used as a terminal to a horizontal rail, originally a part of some temple at Ankor, in Cambodia, the now famous ruin located not far from the lake called Tonic Sap, in the valley of the Mekong River.
A two-level approach to establishing a marketing strategy in the electronic marketplace (2005)

This study concerns an analysis of what kinds of products are more suitable for distribution via the Internet than via traditional markets. The purpose of the analysis is to identify and fit marketing strategy to product in the virtual marketplace. The amount of product information needed by the consumer to reach a purchasing decision varies with the degree of consumer involvement with the purchase. We conjecture that two major factors affect the consumer's disposition toward online shopping: (1) the purchase involvement on the part of consumer, and (2) product information exposure provided by the Web. Therefore, in the virtual market products may be grouped into four categories. The implication of this is that online marketing functions at two levels. (1) Level-1: PNF (primitive network function), which is derived from the primitive network characteristics associated with the product's attributes fitting with the consumer's involvement. (2) Level-2: ANF (advanced network function), which is the marketing communication created by the virtual store to meet the demands of consumers purchasing online.

Factored time-lapse video (2007)

We describe a method for converting time-lapse photography captured with outdoor cameras into Factored Time-Lapse Video (FTLV): a video in which time appears to move faster (i.e., lapsing) and where data at each pixel has been factored into shadow, illumination, and reflectance components. The factorization allows a user to easily relight the scene, recover a portion of the scene geometry (normals), and to perform advanced image editing operations. Our method is easy to implement, robust, and provides a compact representation with good reconstruction characteristics. We show results using several publicly available time-lapse sequences.
Genetic Factors in Anxiety Disorders (1983)

We investigated genetic factors in the determination of anxiety disorders in a study of 32 monozygotic (MZ) and 53 dizygotic (DZ) adult same-sexed twins. The frequency of anxiety disorders was twice as high in MZ as in DZ co-twins of the total proband group, alike in the MZ and DZ co-twins of the generalized anxiety disorder proband group, and three times as high in MZ as in DZ co-twins of the other proband groups. Anxiety disorders with panic attacks were more than five times as frequent in MZ as in DZ co-twins in a combined group of probands with panic disorders and agoraphobia with panic attacks. For generalized anxiety disorder, genetic factors were not apparent, while genetic factors were not apparent, while genetic factors appear to influence the development of the other anxiety disorders, especially panic disorder and agoraphobia with panic attacks.
