<title>Measurement program for the Green Bank Telescope</title> (1998)

The development of metrology instrumentation needed for realization of the active surface and precision pointing for the Green Bank Telescope (GBT) presents the opportunity for a complete characterization of this complex structure prior to the first astronomical observations. It is our intention to use the metrology program to evaluate the completed telescope and to point the way to improvements in performances. We also anticipate using the instrumentation for early detection of possible developing faults in the structure and the foundation. For the first time, it should be possible to derive parameters that determine the repeatable pointing variations as a function of elevation and azimuth position prior to astronomical observations. The measurement program will also give an estimate of the non-repeatable pointing errors resulting from thermal gradients within the structure. Laser rangefinders surrounding the telescope permit the non- invasive measurement of thermal and gravitationally induced deformations within the structure at the 100 micron accuracy level. These measurements, and others, will be used to confirm the finite element analysis of the structure and to predict the performance of the completed telescope. This paper outlines the instrumentation used in the measurement program and gives the results obtained to date. These include dominant modal resonances in the structure, along with the damping coefficients associated with these resonances.
Elemental and Nutritional Analysis of Sea Buckthorn ( <i>Hippophae rhamnoides</i> ssp. <i>turkestanica</i> ) Berries of Pakistani Origin (2005)

Sea buckthorn (Hippophae rhamnoides ssp. turkestanica) is a very important medicinal plant in northern areas of Pakistan. The fruit of sea buckthorn is rich in nutrients and medicinal compounds such as vitamins, carotene, flavonoids, essential oil, carbohydrates, organic acids, amino acids, and minerals. In order to compare various populations of sea buckthorn for chemical composition, eight populations from different areas of northern Pakistan were compared using fruit characteristics. Phytochemical analysis of berries showed vitamin C (250-333 mg/100 g), seed oil (7.69-13.7%), oil in softer pulp (19.2-29.1%), phytosterol content of seed oil (3.3-5.5%), and anthocyanin (0.5-25 mg/L), while the mineral element composition analysis revealed high contents of potassium (140-360 ppm), sodium (20-80 ppm), calcium (70-98 ppm), magnesium (150-240 ppm), iron (40-150 ppm), and phosphorus (110-133 ppm). This study established sea buckthorn berries as a good source of biochemical and mineral elements. The high variation between different populations shows the potential of selecting and breeding of the raw material for various defined purposes.
Modeling of compact Pd coated VCSELs for hydrogen sensing (2011)

We report on designs for compact VCSEL sensors for use in hydrogen gas detection. We discuss 980nm VCSELs coated with Pd, which has been proven to react with hydrogen. During this reaction, the device undergoes hydrogen induced lattice expansion (HILE) which causes two distinct effects that can be detected at the output. These two effects are a red-shift in the emission wavelength and a decrease in the output power. The compact VCSELs will be positioned into a 2D array with varying mesa diameters and palladium thickness in order to distinguish and track the specific level of hydrogen present in the atmosphere.
Evidence for the involvement of central 5‐HT<sub>7</sub> receptors in the micturition reflex in anaesthetized female rats (2003)

(1) The effects of the selective 5-HT7 receptor antagonists SB-269970 (3-300 microg kg-1; n=5-6) and SB-656104 (30 microg kg-1; n=5) administered centrally (i.c.v.) were investigated on the 'micturition reflex' in the urethane anaesthetized female rat. (2) In cystometric recordings, SB-269970 caused significant increases in volume of 58+/-15 and 138+/-33% and pressure of 140+/-46 and 149+/-60% thresholds at 10 and 30 microg kg-1. These changes were associated with significant decreases in distension-induced bladder contraction of 62+/-14 and 60+/-11%, respectively. However, there was no change in residual volume. At the higher doses, SB-269970 blocked the micturition reflex. SB-656104 had similar effects to SB-269970 but in addition significantly increased the residual volume. (3) SB-269970 (10 microg kg-1; n=5) given i.v. had no effect on the micturition reflex. (4) SB-269970 (30 microg kg-1; n=4) given intrathecally (i.t.) had no effect on micturition reflex, although the selective 5-HT1A receptor antagonist WAY-100635 given i.t. after SB-269970 caused a significant increase in the volume threshold. (5) Using an isovolumetric method in which urethral changes were measured, SB-269970 (30 microg kg-1; n=4; i.c.v.) failed to have any effect on these urethral-evoked changes although they significantly reduced the amplitude of the bladder contraction. (6) These data demonstrate that 5-HT7 receptors located supraspinally in the rat are involved in the control of micturition.
A novel approach to depth ordering in monocular image sequences (2002)

Object oriented representation of image sequences requires accurate motion segmentation and depth ordering techniques. Unfortunately, the lack of precise motion estimates at the object boundaries makes these two tasks very difficult. We present a detailed analysis of the behaviour of dense motion estimation techniques at object boundaries which reveals the systematic nature of the motion estimation error; the motion of the occluding surface is observed in a small neighbourhood on the occluded side. We then show how the joint use of still image segmentation and robust regression can eliminate this error. Furthermore we present a novel technique which uses the position of the error as a depth cue. The validity of this technique, which requires only sub-pixel motion and which is capable of distinguishing between different types of intensity discontinuities, such as object boundaries, surface marks and illumination discontinuities, is then demonstrated on several synthetic and real image sequences.
Fabrication of uniform vertically-aligned carbon nanotube–polymer composite thin films by capillary flow intrusion (2018)

Polymer and nanomaterial composites, known as nanocomposites, are advanced materials that have many potential applications. One type of thin-film nanocomposite is a polymer–carbon nanotube (CNT) nanocomposite, whose properties are strongly dependent on the uniformity and alignment of CNTs in the nanocomposite. However, the control of CNT alignment in these nanocomposites is still difficult to achieve. Here, we propose a facile single-step method, a capillary flow intrusion method, to fabricate uniform polymer nanocomposite thin films of vertically aligned (VA) single-/multi-walled CNTs that range from 15 to 300 µm in thickness. Raman scattering spectroscopy and polarized Raman spectroscopy measurements, and cross-sectional scanning electron microscopy (SEM) observations confirmed that the polymer was uniformly infiltrated into VACNTs, such that the alignment of CNTs in the nanocomposite was preserved and there were no excess portions of the polymer. Experimental and numerical calculation results indicated that capillary flow rate, wettability, and polymer shrinkage are important factors in the capillary flow intrusion method.
A new efficient algorithm for singular value decomposition (2003)

The popular CORDIC-based SVDs suffer from the disadvantages of inherently sequential operations and requiring area-consuming barrel shifters. On the other hand, the basic arithmetic SVD needs nasty division and square-root operations. To alleviate these problems, a new algorithm for SVD computation is proposed. Instead of using the CORDIC algorithm, the new algorithm is based on multiplication-and-addition operations (without nasty division and square-root operations), combined with an approximate rotation and table lookup scheme. As a result, the new algorithm has a smaller computational complexity than those of the conventional SVD algorithms, in terms of number of addition operations. In realization, it also has a higher parallelism and smaller area than the conventional CORDIC-based SVD processors.
Effect of recombinant granulocyte colony-stimulating factor on neutrophil kinetics in normal young and elderly humans (1996)

Recombinant granulocyte colony-stimulating factor (G-CSF) was administered to healthy young (n = 32) and elderly (n = 19) volunteers (0 microgram/d, 30 microgram/d, or 300 microgram/d) to determine its effect on neutrophil production, blood kinetics, and tissue migration. Measurements included blood counts (daily), marrow neutrophil pool sizes and neutrophil tissue migration (baseline and day 5), blood kinetics (day 6), and marrow transit time while on drug (days 6 to 14). G-CSF markedly expanded the marrow neutrophil mitotic pool and shortened the transit time of the postmitotic pool (control, mean = 6.4 days; 300 microgram/d, mean = 2.9 d). G-CSF increased neutrophil production without significantly altering blood neutrophil half-life or margination. Compared to control, neutrophil accumulation in skin chambers decreased by about 50% in the 300 microgram/d group in both young and elderly subjects. G-CSF induced neutrophilia by stimulating proliferation of marrow neutrophil precursors and accelerating neutrophil entry into the blood. Decreased neutrophil inflammatory responses measured with the skin chamber technique may be because of the relative immaturity of the circulating cells or to alterations in neutrophil phenotype induced by G-CSF.
DICOM and XML usage for multimedia teleconsultation and for reimbursement in cardiology (2003)

We've defined an open, scaleable telemedicine architecture to reduce the time of reports delivery and consultation; increasing their simplicity via introducing common image capture, compression, storage, presentation- and telecommunication formats and methods for telecardiology based on DICOM. We've developed a software application to implement them in 4 Hungarian and 4 Lithuanian cardiac clinics, introducing the most appropriate digital imaging methods and formats using the latest available technology. We describe data and document exchange among health care providers (hospitals, GPs etc.) and the reimbursing insurance institutes introducing XML technology. We present the most important XML datasets for reimbursement in Hungary, the validation schemas and procedures, comparing the XML and old data file sizes with different compressions and (server and client) XML tools. The comparison includes different schema file sizes, and validation times.
Zinc protection against lipid peroxidation from cadmium. (1991)

Effect of zinc and cadmium on lipid peroxidation and catalase activity in liver, heart, brain and testis was determined in order to characterise the interaction of zinc with cadmium. Zinc and cadmium both increased lipid peroxidation significantly in the tissues studied. In animals pretreated with zinc prior to cadmium administration, significant decrease in lipid peroxidation in liver was observed. Lipid peroxidation was not affected significantly in testis but a significant increase was observed in heart and brain tissues. Catalase activity in testis increased significantly by zinc treatment with or without cadmium administration.
Human intestinal glucose transporter expression and localization of GLUT5 (1992)

We have studied the developmental and regional expression of mRNAs encoding sodium-dependent and facilitative glucose transporter proteins in human fetal and adult small intestine. The abundance of mRNAs encoding the Na(+)-glucose cotransporter isoform SGLT1 and the facilitative glucose transporter isoforms GLUT2 and GLUT5 is developmentally modulated with highest levels in adult small intestine. By contrast, the levels of GLUT1 mRNA are higher in fetal than adult small intestine. Immunohistochemical analysis of adult small intestine localized GLUT5 to the luminal surface of mature enterocytes, a finding confirmed by Western blot analysis of purified human jejunal brush-border membranes. By contrast, in the fetal small intestine, GLUT5 was localized along the intercellular junctions of the developing villus, indicating that both its expression and localization are developmentally regulated. The localization of GLUT5 to the luminal surface of mature absorptive epithelial cells implies that this protein participates in the uptake of dietary sugars.
A Study on the formation of a community in collective housing on public supply (2000)

The purpose of this paper has been to look at examples of "Hyogo Rivial Collective Housing", to find a state of community living on collective housing. And the change of the situation at housing in about one and a half years since the residents started living there was investigated. In the conclusion, in supplying collective housing to people living in public housing, it is necessary to explain to them in detail how to live there comfortably and to let the prospective residents live there on trial so that they can understand fully what the life in collective housing is like.
Nonlinear dynamic maximum power theorem (1988)

The problem of maximizing the energy or average power transfer from a nonlinear dynamic source is considered. The main theorem includes, as special cases, the standard linear result where the load admittance equals the complex conjugate of the source admittance and a recent finding for linear resistive networks. An operator equation for the optimal output voltage is derived, and a numerical method for solving it is given.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Advanced glycosylation endproducts block the antiproliferative effect of nitric oxide. Role in the vascular and renal complications of diabetes mellitus. (1992)

Advanced glycosylation endproducts (AGEs) accumulate on long-lived tissue proteins such as basement membrane collagen and have been implicated in many of the long-term complications of diabetes mellitus. These products originate from glucose-derived Schiff base and Amadori products but undergo a series of complex rearrangement reactions to form ultimately protein-bound, fluorescent heterocycles. AGEs can react with and chemically inactivate nitric oxide (NO), a potent endothelial cell-derived vasodilator and antiproliferative factor. Since mesenchymal cell proliferation is an early and characteristic lesion of diabetic vasculopathy and glomerulopathy, we investigated the possibility that collagen-bound AGEs functionally inactivate the antiproliferative effect of NO. In model cell culture systems, AGEs were found to block the cytostatic effect of NO on aortic smooth muscle and renal mesangial cells. The inactivation of endothelial cell-derived NO by basement membrane AGEs may represent a common pathway in the development of the accelerated vascular and renal disease that accompany long-term diabetes mellitus.
Advanced Compact Holographic Data Storage System (2000)

JPL, under current sponsorship from NASA Space Science and Earth Science Programs, is developing a high-density, nonvolatile and rad-hard Advanced Holographic Memory (AHM) system to enable large-capacity, high-speed, low power consumption, and read/write of data in a space environment. The entire read/write operation will be controlled with electro-optic mechanism without any moving parts. This CHDS will consist of laser diodes, photorefractive crystal, spatial light modulator, photodetector array, and I/O electronic interface. In operation, pages of information would be recorded and retrieved with random access and highspeed. The nonvolatile, rad-hard characteristics of the holographic memory will provide a revolutionary memory technology to enhance mission capabilities for all NASA's Earth Science Mission. In this paper, recent technology progress in developing this CHDS at JPL will be presented.
Bovine Herpesvirus 1 UL49.5 Protein Inhibits the Transporter Associated with Antigen Processing despite Complex Formation with Glycoprotein M (2006)

Bovine herpesvirus 1 (BHV-1) interferes with peptide translocation by the transporter associated with antigen processing (TAP). Recently, the UL49.5 gene product of BHV-1 was identified as the protein responsible for the observed inhibition of TAP. In BHV-1-infected cells and virions, the UL49.5 protein forms a complex with glycoprotein M (gM). Hence, it was investigated whether UL49.5 can combine the interactions with gM and the TAP complex. In cell lines constitutively expressing both UL49.5 and gM, UL49.5 appears to be required for functional processing of gM. Immunofluorescence-confocal laser scanning microscopy demonstrated that both proteins are interdependent for their redistribution from the endoplasmic reticulum to the trans-Golgi network. Remarkably, expression of cloned gM results in the abrogation of the UL49.5-mediated inhibition of TAP and prevents the degradation of the transporter. However, in BHV-1-infected cells, differences in UL49.5 and gM expression kinetics were seen to create a window of opportunity at the early stages of infection, during which time the UL49.5 protein can act on TAP without gM interference. Moreover, in later periods, non-gM-associated UL49.5 can be detected in addition to the UL49.5/gM complex. Thus, it has been deduced that different functions of UL49.5, editing of gM processing and inhibition of TAP, can be combined during BHV-1 infection.
GaN-Based Metal-Insulator-Semiconductor High-Electron-Mobility Transistors Using Low-Pressure Chemical Vapor Deposition SiN<sub><italic>x</italic></sub> as Gate Dielectric (2015)

In this letter, silicon nitride (SiN <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"><i>x</i></sub> ) film deposited at 780 °C by low-pressure chemical vapor deposition (LPCVD) was employed as gate dielectric for GaN-based metal–insulator–semiconductor high-electron-mobility transistors.

The Preservation of Bacteria by Drying (1947)

SUMMARY: A quantitative study of the survival of vegetative bacteria on drying in various suspending media led to a simple method for preserving bacterial cultures. Bacterial cells are suspended in melted nutrient gelatin cont.aining ascorbic acid or sodium ascorbate in concentration of 0·25–0·5%. Small quantities are dried over P2O5 at pressures of 100–300 mm, of mercury and stored in vacuo over P2O5 at room temperature. A wide range of bacterial species of medical and verterinary importance was preserved by this method for 4 years. The slow decline in the number of viable organisms and the high percentage survival rate at 4 years indicate the likelihood of survival for a much longer period. The virulence of a number of pathogenic species was successfully maintained in the dry preparation. The method might well be applied to the preservation of living vaccines. The survival rates with Chromobacterium prodigiosum dried by this method were better than those in preparations subjected to rapid freeze-drying processes. They were, however, unsatisfactory with a few species such as Vibrio cholerae and Neisseria meningitidies.
Rainbow: An OS Extension for Hardware Multitasking on Dynamically Partially Reconfigurable FPGAs (2011)

DPR (Dynamic Partial Reconfiguration) capability found in some of modern FPGAs allows implementation of a concept of a HW (Hardware) task, which similarly to its software counterpart has its state and shares time-multiplexed resources with the other tasks. While the new technology presents many advantages for embedded systems where run-time adaptability is an additional requirement, their efficient and easily portable implementations require a control software or an OS which would manage all the complexities of the underlying technology, providing an abstracted interface for the application programmer. This paper presents a novel and robust hardware multitasking extension for a conventional OS, managing task scheduling and configurations, and providing easy-to-use API (Application Programming Interface) for the application programmer. Scheduling is priority-based and takes advantage of task caching. Moreover, the extension is based on a developed design flow and embedded hardware platform allowing efficient task preemption, which can be utilized whenever it presents any benefits to the application.
Series Hybrid Powertrain Based on the Dual Two-Level Inverter (2008)

A multilevel converter in the 'dual two level' configuration is proposed as the core of a hybrid series powertrain. The generation system of the powertrain is constituted by an internal combustion engine (ICE) connected to a three-phase permanent magnet synchronous generator (PMSG). This machine is in the three phase open end winding configuration and is driven by the dual two- level converter. The two dc-link of the multilevel converter supply two motor drives connected to the final mechanical transmission. A new control principle of the generation system is combined to a proper modulation strategy of the dual two- level converter allowing to share the generated power between the two output drives. The power sharing capability of the generation system satisfies the different power demand from the two output drives. This architecture can be applied to road vehicles (i.e. buses, urban light truck) where the two wheels are driven by the two motor drives, and to naval ship propulsion systems (i.c leisure craft, work craft) where two propeller shafts are driven by two motor drives. This powertrain configuration can be easily integrated with a battery energy storage system for pure electric operation of the system.
Chicken α-Enolase but Not β-Enolase Has a Src-Dependent Tyrosine-Phosphorylation Site: cDNA Cloning and Nucleotide Sequence Analysis1 (1995)

Chicken alpha- and beta-enolase cDNAs have been cloned and analyzed to reveal that alpha- but not beta-enolase has a Src-dependent phosphorylation site. The deduced amino acid sequence of the chicken alpha-enolase showed more than 90% homologies with those of other vertebrate alpha-enolases including amphibian (Xenopus laevis) alpha-like enolase. The chicken beta-enolase, on the other hand, shares 84-85% amino acid sequence homology with mammalian beta-enolases. These chicken enolases also showed more than 70% sequence identity with an insect (Drosophila melanogaster) enolase and around 60% with two yeast enolases. The amino acid sequence between residues 33 and 50 in chicken alpha-enolase coincided with the reported tryptic peptide sequence of rabbit beta-enolase, the tyrosine residue in which was phosphorylated in vitro by Rous-sarcoma-virus tyrosine kinase. The present finding suggested that the tyrosine residue at position 44 in chicken alpha-enolase is the phosphorylation site by the tyrosine kinase. In chicken beta-enolase, on the other hand, the corresponding tyrosine residue was found to be replaced with a histidine residue, in accordance with the previous observation that chicken beta-enolase was not phosphorylated in vivo or in vitro. Northern blot analysis indicated that alpha-enolase mRNA can be expressed in a wide range of chicken tissues, and that the gene expression switch from alpha to beta-enolase occurs just after hatching in developing chicken muscle.
