Large Solar Arrays -The Emerging Space Power Workhorse (1969)

The solar array/secondary battery system has emerged as the space power "workhorse". Previously considered only for applications of up to 1 KW e , arrays of up to 3 KWe have been flown. Even larger arrays (10 KWe ) are being developed for Apollo Telescope Mount (ATM) and the "wet" Orbital Workshop. An Earth Orbiting Space Laboratory (EOSL) , in the planning state for a 1973- 1975 flight readiness date, is considering the use of a 38 KWe solar array system. A 50 KW e array is under development for an electric propulsion mission and a 45 KWe array is in the conceptual design phase for a lunar surface application. Finally, a study has been initiated to assess the practicability and cost effectiveness of utilizing a 1 MWe array for earth orbital applications. An intense technology development program has been underway for several years. The emphasis has been on solving problems that relate directly toward utilization of large solar arrays. These have included light weight structures, improved power distribution and cost reduction techniques. This paper discusses the various approaches being taken by both government and industry to resolve these problems.
Testing Web applications (2003)

The rapid diffusion of Internet and open standard technologies is producing a significant growth of the demand of Web sites and Web applications with more and more strict requirements of usability, reliability, interoperability and security. While several methodological and technological proposals for developing Web applications are coining both from industry and academia, there is a general lack of methods and tools to carry out the key processes that significantly impact the quality of a Web application (WA), such as the validation & verification (V&V), and quality assurance. Some open issues in the field of Web application testing are addressed in this paper. The paper exploits an object-oriented model of a WA as a test model, and proposes a definition of the unit level for testing the WA. Based on this model, a method to test the single units of a WA and for the integration testing is proposed. Moreover, in order to experiment with the proposed technique and strategy, an integrated platform of tools comprising a Web application analyzer, a repository, a test case generator and a test case executor, has been developed and is presented in the paper. A case study, carried out with the aim of assessing the effectiveness of the proposed method and tools, produced interesting and encouraging results.
New Crystal Form of Recombinant Murine Interferon-β (1989)

Although we have reported (Matsuda, S., Kawano, G., Itoh, S., Mitsui, Y., and Iitaka, Y. (1986) J. Biol. Chem. 261, 16207-16209) that recombinant murine interferon-beta produced in Escherichia coli was crystallized in an orthorhombic space group C222(1) using polyethyleneglycol 8000 as precipitant, the crystals had an insufficient resolution and a marked tendency for orientational disorder around the c axis. We now report that another form of murine interferon-beta crystals with little disorder was obtained in the presence of dioxane using ammonium sulfate as precipitant. The new crystals belong to a hexagonal space group P6(1) or P6(5) with a = b = 71.4 A and c = 79.6 A having only one murine interferon-beta molecule in an asymmetric unit. The crystals are reasonably stable to x-rays and significantly diffract up to 2.2 A resolution when a synchrotron beam is used.
Optimal AdvInterval for BLE scanning in different number of BLE devices environment (2016)

The Bluetooth Low Energy (BLE) is one of promising technologies widely used for Internet of things (IoT) services because of its low energy consumption. In IoT, BLE gateways should discover surrounding BLE devices in a short time. However, this requirement is difficult to achieve when the number of BLE devices is very large. As the number of BLE devices increase, the signal density increase, and the collision problems become more serious. In this paper, we analyze the performance of BLE by considering both signal collision and density. The simulation results show that there exists the optimal AdvInterval for given number of BLE devices.

Magnetic properties of the MnBi intermetallic compound (2001)

A MnBi alloy containing over 90 wt % low-temperature phase (LTP) has been obtained by high-temperature sintering and magnetic purification. The coercivity of the bonded MnBi magnet increases with increasing temperatures. A coercivity of 2.0 T has been achieved at 400 K. The maximum energy product (BH)max of the magnet is 7.7 MGOe (61 kJ/m3) and 4.6 MGOe (37 kJ/m3) at room temperature and 400 K, respectively. Neutron diffraction and magnetic data reveal a spin reorientation, which gives rise to low anisotropy fields and coercivity at lower temperatures for the LTP MnBi alloy.
Prediction of Building Integrated Photovoltaic Cell Temperatures* (2001)

A barrier to the widespread application of building integrated photovoltaics (BIPV) is the lack of validated predictive performance tools. Architects and building owners need these tools in order to determine if the potential energy savings realized from building integrated photovoltaics justifies the additional capital expenditure. The National Institute of Standards and Technology (NIST) seeks to provide high quality experimental data that can be used to develop and validate these predictive performance tools. The temperature of a photovoltaic module affects its electrical output characteristics and efficiency. Traditionally, the temperature of solar cells has been characterized using the nominal operating cell temperature (NOCT), which can be used in conjunction with a calculation procedure to predict the module’s temperature for various environmental conditions. The NOCT procedure provides a representative prediction of the cell temperature, specifically for the ubiquitous rack-mounted installation. The procedure estimates the cell temperature based on the ambient temperature and the solar irradiance. It makes the approximation that the overall heat loss coefficient is constant. In other words, the temperature difference between the panel and the environment is linearly related to the heat flux on the panels (solar irradiance). The heat transfer characteristics of a rack-mounted PV module and a BIPV module can be quite different. The manner in which the module is installed within the building envelope influences the cell’s operating temperature. Unlike rack-mounted modules, the two sides of the modules may be subjected to significantly different environmental conditions. This paper presents a new technique to compute the operating temperature of cells within building integrated photovoltaic modules using a one-dimensional transient heat transfer model. The resulting predictions are compared to measured BIPV cell temperatures for two single crystalline BIPV panels (one insulated panel and one uninsulated panel). Finally, the results are compared to predictions using the NOCT technique.

Quantitative measurement of NO density by resonance three-photon ionization (1984)

An ionization probe and measurement procedures are developed to permit accurate NO density measurements with good spatial and temporal resolution and with the high sensitivity and good discrimination inherent in resonance-enhanced multiple-photon ionization processes. The use of NO as a calibration standard for density measurements of other molecules and combustion radicals is discussed.
Induction of suppressor T cells in asthmatic children by theophylline treatment (1983)

The absolute T-cell numbers and function, and the T-suppressor-cell subset were tested in eleven children with extrinsic asthma prior to and 1 month after theophylline treatment. Low mean T-suppressor-cell number and function was found in the asthmatic children, which returned to normal levels and function after 1 month of theophylline treatment. A normal mean T-cell number was found in this group of children prior to, and 1 month after, theophylline treatment. An obvious correlation between the clinical severity of the asthma and the number of T suppressor cells was found. It is suggested that theophylline most probably activated the T suppressor cells in the asthmatic children.
Magnitude and polarity of a fluoroethylene propylene electret substrate charge influences neurite outgrowth <i>in vitro</i> (1993)

Positively charged coating materials such as polylysine improve neuronal attachment in vitro. Due to the structural complexity of these charged molecules, it is unclear whether neuronal effects are due to charge or to physicochemical effects, or both. Polymeric materials with charge storage capabilities and defined surface properties may provide a model in which electrical charge and surface property effects can be separated. Fluorinated ethylenepropylene (FEP) films can store negative or positive charges injected through a corona charging process, thus generating a negative or positive external electrostatic field. In the present study, mouse neuroblastoma (Nb2a) cells were cultured on positive, negative, and uncharged FEP substrates, in both serum-containing and serum-free media. Cell attachment, differentiation, and neurite outgrowth were assessed 24, 48, 72 and 96 h after plating. Electron spectroscopy for chemical analysis (ESCA), contact angle analysis, and scanning electron microscopy (SEM) revealed no differences in surface chemistry and topography between positive, negative, and uncharged FEP. No significant differences in the levels of cell attachment on positive, negative, and uncharged substrates were observed. Significantly higher levels of neurite outgrowth, however, were observed with positive substrates as compared to negative and uncharged substrates, in both media conditions. Substrates charged to +1000 V showed greater levels of outgrowth compared to +500 and +3000 V, suggesting the presence of an optimal range of charge for neurite outgrowth. These results show that cell/charge interactions mediate cell effects on electrically charged substrates with identical surface chemistry, topography and adhesivity.
Development of a riboflavin and ultraviolet light‐based device to treat whole blood (2013)

Background In the U nited S tates, blood components are commonly used for patients in need of massive transfusion after blood loss. In combat situations, when severe traumatic injuries occur far from a hospital, fresh whole blood is a valuable transfusion therapy because components may not be available. The risk of infectious or immunological complications from fresh whole blood transfusions could be mitigated by a system that reduces pathogen loads and inactivates white blood cells ( WBCs ). Such a system is in development and utilizes riboflavin and ultraviolet light to provide pathogen reduction and WBC inactivation. Study Design and Methods The system has been tested with in vitro and in vivo animal studies to evaluate WBC inactivation and pathogen reduction, and with in vitro studies to assess the function of the treated blood products. Results Elimination of viable WBCs with the system is equivalent to gamma‐irradiation. Results have been reported for reduction of B abesia microti , T rypanosoma cruzi , HIV , and bacteria, and preliminary results for B abesia divergens are available. Treated whole blood, platelets, and plasma maintain coagulation function. Treated red blood cell components exhibit low hemolysis and high adenosine triphosphate levels at the end of storage. Conclusions Treatment with riboflavin and ultraviolet light is a promising alternative to gamma‐irradiation. Effectiveness of the system against a variety of pathogens has been established, and further studies are planned. The in vitro studies of function indicate that treated whole blood, as well as components from treated whole blood, will provide acceptable hemostasis and perform well in the next phase of in vivo studies.

Asymmetric-Cladding 1480-nm Pump Laser with CW Fiber Output Power of 1 W (2003)

High-power 1480-nm lasers operating in the fundamental lateral mode are attractive candidates for erbium doped fiber amplifier (EDFA) and Raman amplifiers. Several approaches have been reported to improve output optical power 1−3. A significant problem is the degraded slope efficiency with increased cavity length. Reduction of internal loss is very effective to overcome this degradation which is caused by inter valence band absorption (IVBA) in the p-cladding layer. We have proposed adoption of an asymmetric cladding layer structure to decrease internal optical loss caused by IVBA in the p-cladding layer. 4 In this work we demonstrate that asymmetric cladding LD achieved the excellent fiber coupling efficiency of 92 % and single-mode fiber output power of 1W.

A fast-adaptive Huffman coding algorithm (1993)

The Huffman code in practice suffers from two problems: the prior knowledge of the probability distribution of the data source to be encoded is necessary, and the encoded data propagate errors. The first problem can be solved by adaptive coding, while the second problem can be partly solved by segmenting data into segments. However, the adaptive Huffman code performs badly when segmenting data into relatively small segments because of its relatively slow adaptability. A fast-adaptive coding algorithm which tracks the local data statistics more quickly, thus yielding better compression efficiency, is given.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Enhanced Rates and Magnitude of Immune Responses Detected against an HIV Vaccine: Effect of Using an Optimized Process for Isolating PBMC (2007)

Quantitative analysis of cell-mediated immune responses induced by candidate HIV vaccines requires robust procedures for collecting and processing human peripheral mononuclear blood cells (PBMCs). We evaluated several parameters in order to optimize a sample handling process that would be suitable for a multicenter clinical trial. Among the findings, systematic increases in the magnitude of IFN-gamma ELISpot responses were observed when the time from blood collection to PBMC freezing was reduced to <12 h. By implementing these improvements within an ongoing clinical trial, the estimated immunologic response rates to an adenovirus- based HIV vaccine increased by more than 20 percentage points to approximately 80% of the vaccine recipients against any of the vaccine antigens and the average levels of T cell response improved more than 3-fold. These studies establish the importance of optimal conditions for PBMC collection and handling to the success of a clinical development program.
SFA-1/PETA-3 (CD151), a member of the transmembrane 4 superfamily, associates preferentially with alpha 5 beta 1 integrin and regulates adhesion of human T cell leukemia virus type 1-infected T cells to fibronectin. (1998)

In this study we have analyzed the adhesion molecules associated with and the biologic function of SFA-1/PETA-3 (CD151) in human T cell leukemia virus type 1 (HTLV-1)-infected T cells and in freshly isolated adult T cell leukemia (ATL) cells using an anti-CD151 mAb. The anti-CD151 mAb coprecipitated alpha 5 beta 1 integrin from HTLV-1-infected T cells. Conversely, an anti-alpha 5 integrin mAb coprecipitated CD151. The anti-CD151 mAb inhibited the adhesion of HTLV-1-infected T cells to fibronectin but did not have any effect on their adhesion to laminin, collagen type I, or collagen type IV. Moreover, antisense CD151 oligonucleotide-treated HTLV-1-infected T cells showed significant inhibition of adhesion to fibronectin. These findings showed that the CD151 molecule was associated with the alpha 5 beta 1 integrin molecule and that it enhanced alpha 5 beta 1 integrin-mediated adhesion to fibronectin. In addition, the expression levels of CD151, alpha 4 beta 1 integrin, and alpha 5 beta 1 integrin on ATL cells from lymph nodes of lymphoma-type ATL patients were significantly higher than those on circulating ATL cells from leukemia-type ATL patients. This suggests that the increased expression of these integrins may contribute to lymphoma formation through the adhesion of ATL cells to the extracellular matrix and dendritic cells, rather than contributing to transmigration.
