The Concentration of Neurotransmitter Metabolites in the Cerebrospinal Fluid of Suicidal Individuals: a Meta-Analysis (1995)

A review of 27 research reports on the cerebrospinal fluid levels of neurotransmitter metabolites involving 1202 psychiatric patients found strong evidence for the involvement of the serotonin system in suicidal behavior. Attempted suicides, especially those using violent methods, had lower levels of CSF 5-HIAA as compared to psychiatric controls, and those making subsequent suicidal actions also had lower levels of CSF 5-HIAA. The meta-analysis permitted more reliable conclusions to be drawn than did each individual study alone.
[DNA typing methods of HLA]. (1999)

Human leukocyte antigens (HLA) are a group of cell membrane proteins encoded by the HLA gene complex on the short arm of the chromosome 6, with a high degrees of polymorphism, and a total of about 650 alleles have been identified at HLA-A, B, C and DR loci up to now, which regulate the immune response by self/not-self discrimination. A number of DNA-based typing methods using specific primers, specific probes or restriction enzymes have been developed. In HLA allele typing, a few methods which are simple in handling and able to determine the alleles automatically, have been available.
Prediction-based network bandwidth control (2002)

The fractional autoregressive integrated moving average, FARIMA (p,d,q) model, is capable of capturing both the long-range and short-range dependence in the video traffic. We propose a prediction-based bandwidth allocation scheme for integrated service packet networks using the FARIMA (p,d,q) model. Our simulation experiments show that this scheme can significantly reduce the requirement of buffer size and the frame loss rate.
In-Situ Generation of Carbon Dioxide: New Way To Increase Oil Recovery (2000)

Abstract Miscible/Immiscible carbon dioxide injection is considered to be as one of most effective technology to improve oil recovery from complicated formations, and hard to recover oil reserves, in particular. Application of this technology can increase ultimate oil recovery by 10-15% and even more1. One of the main advantage of this technology is that it can be applied in a wide range of geological conditions for production both light and heavy oils. Striking illustration of this technology high efficiency is the fact that the number of active carbon dioxide (CO2) projects worldwide sharply increased during last 20 years, from 30-35 in the beginning of 1980s to almost 100 in 2000, while oil production increased from 25,000 BPD to more than 200,000 BPD during this period 2. One of the main factor restraining wide application of this technology is its dependence on the natural CO2 sources, transportation of CO2, breakthrough of CO2 to production wells, corrosion of well and field equipment, safety and environmental problems etc. Except Hungary reserves of natural CO2 for field application of this technology are not existed in Europe. This restrains wide implementation of CO2 injection not only in many European countries but also worldwide where this technology could be efficiently applied and significantly improve oil production as well as ultimate oil recovery from depleted oil formations. Carbon dioxide enhanced oil recovery may be the key to recovering huge amount of oil from highly watered, depleted, heterogeneous and other type of so called "hard-to-recover" oil reserves. One of the main advantage of proposed technology is eliminating of CO2 negative impact on the environment and strong control of the process. New understanding of the nature of miscible displacement process when behavior of CO2 can be explain as a "super critical fluid" opens a unique future of oil displacement using this technology. Results of R & D as well as new approach in estimation of the efficiency of EOR technology application are described below. Proposed technology of in-situ CO2 generation is based on exothermic chemical reaction between gas forming water solution and low concentrated active acids.
Gel phase polymorphism in ether-linked dihexadecylphosphatidylcholine bilayers (1987)

The structure and properties of the ether-linked 1,2-dihexadecylphosphatidylcholine (DHPC) have been examined as a function of hydration. By differential scanning calorimetry, DHPC exhibits an endothermic (chain melting) transition with the transition temperature (limiting value, 44.2 degrees C) and enthalpy (limiting value, delta H = 8.0 kcal/mol) being hydration dependent. For hydration values greater than 30 wt % water, DHPC exhibits a pretransition at approximately 36 degrees C (delta H = 1.1 kcal/mol) and a subtransition at approximately 5 degrees C (delta H = 0.2 kcal/mol). By X-ray diffraction, at 22 degrees C DHPC exhibits a normal bilayer gel structure with the bilayer periodicity increasing from 58.0 to 62.5 A over the hydration range 9.5-25.4% water. At 30-32% water, two coexisting gel phases are observed with d = 63-64 A and d = 44-45 A; at higher hydration, only the latter phase is present, reaching a limiting d = 47.0 A at 37.5% water. Two different gel phases clearly exist at low and high hydrations. Electron density profiles at low hydration (9.5-25.4%) show a bilayer thickness dp-p = 46 A, whereas at greater than 32% water the bilayer thickness is markedly reduced, dp-p = 30 A. These and other structural parameters indicate a hydration-dependent gel----gel structural transition between a normal bilayer (two chains per polar group) and the chain-interdigitated bilayer (four chains per polar group) arrangement described previously for DHPC [Ruocco, M.

Flame‐induced atmospheric pressure chemical ionization mass spectrometry (2016)

In FAPCI, analytes are not incinerated but vaporized and introduced into the ion source to react with the reactive charged species generated by a flame. The features of the FAPCI source include: configuration is very simple, operation is easy, high voltage or inert gas is unnecessary, and the source is maintenance free. Various combustible gases, solvents and solids are useful flame fuels for FAPCI. Copyright © 2016 John Wiley & Sons, Ltd.
Volume ray casting techniques and applications using general purpose computations on graphics processing units (2009)

Traditional 3D computer graphics focus on rendering the exterior of objects. Volume rendering is a technique used to visualize information corresponding to the interior of an object, commonly used in medical imaging and other fields. Visualization of such data may be accomplished by ray casting; an embarrassingly parallel algorithm also commonly used in ray tracing. There has been growing interest in performing general purpose computations on graphics processing units (GPGPU), which are capable exploiting parallel applications and yielding far greater performance than sequential implementations on CPUs. Modern GPUs allow for rapid acceleration of volume rendering applications, offering affordable high performance visualization systems. \tThis thesis explores volume ray casting performance and visual quality enhancements using the NVIDIA CUDA platform, and demonstrates how high quality volume renderings can be produced with interactive and real time frame rates on modern commodity graphics hardware. A number of techniques are employed in this effort, including early ray termination, super sampling and texture filtering. In a performance comparison of a sequential versus CUDA implementation on high-end hardware, the latter is capable of rendering 60 frames per second with an impressive price-performance ratio heavily favoring GPUs. \t \tA number of unique volume rendering applications are explored including multiple volume rendering capable of arbitrary placement and rigid volume registration, hypertexturing and stereoscopic anaglyphs, each greatly enhanced by the real time interaction of volume data. The techniques and applications discussed in this thesis may prove to be invaluable tools in fields such as medical and molecular imaging, flow and scientific visualization, engineering drawing and many others.
A new chemical ionization mass spectrometer technique for the fast measurement of gas phase nitric acid in the atmosphere (1998)

A new chemical ionization mass spectrometer (CIMS) technique has been developed for the measurement of HNO 3 . The technique has been field tested and informally intercompared with a standard filter pack method, and a new CIMS technique developed by the National Oceanic and Atmospheric Administration Aeronomy Laboratory. The technique has been shown under lab conditions to have sensitivities as high as 0.2 parts per trillion volume (pptv) HNO 3 for a 1 s integration of each the reagent and product ions, with a typical clean air field detection limit of 1–3 pptv for the same integration times. The new technique also responds quickly to changes in HNO 3 concentrations. The high sensitivity and fast response time make this technique well suited for airborne measurements.
Design and Experimental Analysis of an Exhaust Air Energy Recovery Wind Turbine Generator (2015)

A vertical axis wind turbine (VAWT) was positioned at the discharge outlet of a cooling tower electricity generator. To avoid a negative impact on the performance of the cooling tower and to optimize the turbine performance, the determination of the VAWT position in the discharge wind stream was conducted by experiment. The preferable VAWT position is where the higher wind velocity matches the positive torque area of the turbine rotation. With the proper matching among the VAWT configurations (blade number, airfoil type, operating tip-speed-ratio, etc.) and exhaust air profile, the turbine system was not only able to recover the wasted kinetic energy, it also reduced the fan motor power consumption by 4.5% and increased the cooling tower intake air flow-rate by 11%. The VAWT had a free running rotational speed of 479 rpm, power coefficient of 10.6%, and tip-speed-ratio of 1.88. The double multiple stream tube theory was used to explain the VAWT behavior in the non-uniform wind stream. For the actual size of a cooling tower with a 2.4 m outlet diameter and powered by a 7.5 kW fan motor, it was estimated that a system with two VAWTs (side-by-side) can generate 1 kW of power which is equivalent to 13% of energy recovery.
Selective sensing of zinc ions with a novel magnetic resonance imaging contrast agent† (2001)

Light-based microscope imaging techniques using fluorescence sensor molecules suffer from photobleaching and light scattering, but magnetic resonance imaging (MRI) can provide three-dimensional imaging without these problems. Recently, “smart” MRI contrast agents which modulate the access of water to a chelated gadolinium (Gd3+) ion in the presence or absence of a specific trigger have been reported. Zinc (Zn2+) is an essential component of many enzymes, transcription factors and synaptic vesicles in excitatory nerve terminals, so imaging of chelatable Zn2+ is of interest. We have designed and synthesized the Gd3+ DTPA bisamide complex 7a as a Zn2+-sensitive MRI contrast agent. Compound 7a shows a dose-dependent change in the R1 relaxivity in the presence of Zn2+. We investigated this relaxation behavior, and for this purpose we also synthesized the Gd3+ DTPA amide ethyl ester complex 7b. It was shown that binding between 7a and Zn2+ caused a change in the relaxation time. Moreover, 7a had high selectivity for Zn2+ against Ca2+ and Mg2+. Compound 7a may have practical problems for in vivo usage, since the R1 relaxivity is reduced with increased Zn2+ concentration. However, this report demonstrates new approaches to the design and synthesis of Gd3+ complexes with R1 values that change with variation in Zn2+ concentration.
Cyclopentadienyl−Carboranyl Hybrid Compounds:  A New Class of Versatile Ligands for Organometallic Chemistry (2002)

A new class of organic-inorganic hybrid compounds bearing a cyclic pi-ligand, an icosahedral carborane moiety, and a bridging group has been developed. These are very versatile ligands, featuring both an organic and an inorganic moiety as well as a bridging ligand. They can be readily converted into mono-, di-, tri- and pentaanionic species under suitable reaction conditions, leading to the generation of a new class of organometallic compounds in which the carboranyl unit can be cast in the role of a bulky substituent, a sigma-, eta(5), eta(6), or eta(7) pi-ligand. This Account provides an overview of our recent work in this area.
Identification and modulation of electronic band structures of single-phase β-(AlxGa1−x)2O3 alloys grown by laser molecular beam epitaxy (2018)

Understanding the band structure evolution of (AlxGa1−x)2O3 alloys is of fundamental importance for developing Ga2O3-based power electronic devices and vacuum ultraviolet super-radiation hard detectors. Here, we report on the bandgap engineering of β-(AlxGa1−x)2O3 thin films and the identification of compositionally dependent electronic band structures by a combination of absorption spectra analyses and density functional theory calculations. Single-monoclinic β-phase (AlxGa1−x)2O3 (0 ≤ x ≤ 0.54) films with a preferred (−201) orientation were grown by laser molecular beam epitaxy with tunable bandgap ranging from 4.5 to 5.5 eV. The excellent fitting of absorption spectra by the relation of (αhν)1/2 ∝ (hν-E) unambiguously identifies that β-(AlxGa1−x)2O3 alloys are indirect bandgap semiconductors. Theoretical calculations predict that the indirect nature of β-(AlxGa1−x)2O3 becomes more pronounced with increased Al composition due to the increased eigenvalue energy gap between M and Г points in the valence band. The experimentally determined indirect bandgap exhibits almost a linear relationship with Al composition, which is consistent with the theoretical calculation and indicates a small bowing effect and a good miscibility. The identification and modulation of (AlxGa1−x)2O3 band structures allows rational design of ultra-wide bandgap oxide heterostructures for the applications in power electronics and solar-blind or X-ray detection.
IrSi Schottky-barrier infrared detectors with 10- mu m cutoff wavelength (1988)

IrSi Schottky-barrier detectors were fabricated with approximately 40-AA-thick silicide electrodes formed on p-type Si substrates by in situ processing in a conventional electron-beam evaporator. High-resolution transmission electron microscopy shows that these detectors have clean, abrupt silicide-Si interfaces. For operation at a reverse-bias voltage of 2 V, the cutoff wavelength is approximately 10 mu m, as determined by quantum efficiency measurements.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

Characterization of colonic cellular glycoconjugates in colitis and cancer-prone tamarins versus colitis and cancer-resistant primates. (1988)

Differences in colonic secretory glycoconjugates (ie, mucin) between normal and ulcerative colitis-prone patients have been noted. Similar differences may occur in a corresponding primate model, the cotton-top tamarin (CTT), Saguinus oedipus, a New World monkey which suffers from spontaneous chronic colitis and colon cancer. Lectin reagents were used to characterize and compare colonic cell surface, cytoplasmic, and secretory glycoconjugates of 9 clinically healthy cotton-top tamarins, 7 colitis-susceptible, cancer-resistant tamarins (Callithrix jacchus, Saguinus fuscicollis), and 8 colitis and cancer-resistant primates (Aotus trivirgatus, Saimiri sciureus, Macaca fascicularis, and Macaca mulatta). Paraffin-embedded colonic sections were labeled with ten different biotinylated lectins and visualized by the avidin-biotin peroxidase (ABC) method. Significant differences were demonstrated in the pattern of lectin staining between the colitis-resistant and colitis-prone groups of primates. The differences were noted with Griffonia simplicifolia-I (GS-I), Dolichos biflorus agglutinin (DBA), peanut agglutinin (PNA) before and after neuraminidase, Ricinus communis agglutinin-I (RCA-I), soybean agglutinin (SBA), Ulex europaeus agglutinin-I (UEA-I), wheat germ agglutinin (WGA), and succinylated WGA (S-WGA). Significant differences between the CTT and phylogenetically related colitis-prone but cancer-resistant tamarins were demonstrated with SBA, UEA-I, and PNA after desialylation with neuraminidase. These results suggest that differences in colonic cellular glycoconjugates between colitis- and cancer-susceptible species versus colitis-susceptible, cancer-resistant species may be associated with risk of cancer.
Stability, Instability and Chaos (1994)

By providing an introduction to nonlinear differential equations, Dr Glendinning aims to equip the student with the mathematical know-how needed to appreciate stability theory and bifurcations. His approach is readable and covers material both old and new to undergraduate courses. Included are treatments of the Poincaré-Bendixson theorem, the Hopf bifurcation and chaotic systems. The unique treatment that is found in this book will prove to be an essential guide to stability and chaos.
Mixin layers (2002)

A "refinement" is a functionality addition to a software project that can affect multiple dispersed implementation entities (functions, classes, etc.). In this paper, we examine large-scale refinements in terms of a fundamental object-oriented technique called collaboration-based design. We explain how collaborations can be expressed in existing programming languages or can be supported with new language constructs (which we have implemented as extensions to the Java language). We present a specific expression of large-scale refinements called mixin layers , and demonstrate how it overcomes the scalability difficulties that plagued prior work. We also show how we used mixin layers as the primary implementation technique for building an extensible Java compiler, JTS.
Cloning and expression of the SPARC cDNA from rainbow trout (1997)

A trout SPARC cDNA has been isolated and the sequence is highly conserved. The encoded protein shows 76% identity and 91% similarity between trout and human. Like the frog protein, trout SPARC deduced protein has one potential n ‐glycosylation site in position 96. SPARC mRNA was detected from brain tissue as early as hatching day. The transcript level increased rapidly during the early postnatal period and maintained high levels in adulthood. By week 7, the mRNA level was 11 times higher than that at hatching day. The pituitary gland showed a strong signal of SPARC mRNA, and it was detected also with high expression in muscle, gill and brain, and at the lowest level in the liver. These results demonstrate that SPARC is widely distributed in trout and suggest that SPARC has multiple functions. It may play a critical role in early brain development, such as cell migration, proliferation and angiogenesis. It is proposed also that SPARC modulates pituitary hormone release through regulation of the degradation of the extracellular matrix.

Deep Learning for Automatic IC Image Analysis (2018)

We propose a systematic training and validation approach for obtaining a deep learning model for automatic IC image analysis, i.e. IC image semantic segmentation. Our approach divides IC images into different regions of interest and provides for noise rejection training. We discuss steps for obtaining such a model. By experiment and by comparison with competing image processing techniques, deep learning models obtained by our approach demonstrate good generalization capability, high prediction accuracy and low circuit annotation error.
A Serine/Threonine Protein Kinase from<i>Mycobacterium tuberculosis</i> (1997)

Genomic DNA sequencing in the vicinity of the pstA-1 gene from Mycobacterium tuberculosis allowed us to clone, sequence and identify a gene encoding a 70-kDa protein. The size of the protein was confirmed by in vitro coupled transcription/translation. Its N-terminal domain shows extensive sequence similarity with the catalytic domain of eukaryotic serine/threonine protein kinases, and the protein was therefore called Mbk (mycobacterial protein kinase). The deduced amino acid sequence contains two transmembrane segments, which flank a highly repetitive region, suggesting a receptor-like anchoring. The mbk gene was overexpressed in Escherichia coli and the gene product (Mbk) was purified as a fusion protein with gluthatione S-transferase. Recombinant Mbk was found to be autophosphorylated on threonine residues and capable of phosphorylating myelin basic proteins from bovine brain and histones from calf thymus on serine residues, both in a manganese-dependent manner. The phosphorylation of myelin basic proteins by Mbk was inhibited by calcium and by staurosporine, a widely used inhibitor of eukaryotic protein serine/threonine kinases. A similar gene was found in Mycobacterium bovis BCG DNA by Southern blot analysis. Its expression was detected in cultures of M. bovis BCG by reverse transcriptase/PCR. Although its biological role is unknown, it is the first serine/threonine protein kinase characterized in Mycobacteria.
