Sheetlike Waveguide for 2.4 GHz and 5 GHz Bands (2010)

We present a useful design for a free access mat which supports two frequency bands of 2.4 GHz and 5 GHz. The free access mat is a sheet-shaped waveguide which consists of a tightly coupled double-layered microstrip resonator array. It provides easy access for devices in short-range wireless communications. Interference is a common problem with conventional applications which use free space transmission. Our proposed wireless access system uses a subsidiary waveguide, the free access mat. Wireless devices are proximately coupled to the free access mat through which the coupled electromagnetic (EM) wave transmits. The arrival domain of the EM wave of an application is therefore limited to an area close to the free access mat. Wireless devices can be coupled to the free access mat at an arbitrary position without contact. We previously presented a free access mat for a single frequency band. This paper presents a free access mat for the two frequency bands of 2.4 GHz and 5 GHz. The free access mat uses a ring patch resonator array which is easily excited by typical antennas and is resistant to interference. These characteristics are demonstrated by numerical simulation and confirmed by experiment.
Considering noise orbital deviations on the evaluation of power density spectrum of oscillators (2006)

This brief presents a new application of the theory of noise in free running oscillators based on the Floquet eigenvector decomposition. In oscillators, all orbital deviations contribute to the power density spectrum (PDS) as much as the "phase" term, usually considered. Each orbital deviation component shows a time evolution depending on the related Floquet eigenvalue, which thus characterizes statistical properties related to that component. Orbital deviations are partially correlated, due to their common origin from noise sources, thus also correlation terms are considered in the evaluation of the PDS. In this brief, we introduce a simplified method of calculation of PDS and apply it to an example of RLC negative resistance oscillator. Results show the relevance of orbital deviations in PDS in presence of stationary noise, these contributions becomes particularly relevant when noise is cyclostationary
First Wideband 520-590 GHz Balanced Fundamental Schottky Mixer (2007)

We report on the design and performance of a novel broadband, biasable, balanced fundamental 520-590 GHz fix-tuned frequency mixer that utilizes planar Schottky diodes. The suspended stripline circuit is fabricated on a GaAs membrane mounted in a split waveguide block. The chip is supported by thick beam leads that are also used to provide precise RF grounding, RF coupling and DC/IF connections. At room temperature, the mixer has a measured DSB noise temperature of 2200 K at the low end of the band, and less than 4000 K across the design band. Index Terms — Submillimeter wave mixers, Schottky diode mixers, Submillimeter wave diodes.

Differential hormonal responsiveness of the ovalbumin gene and its pseudogenes in the chick oviduct (1980)

We describe the isolation of recombinant phages from a chicken gene library which contain two genes designated X and Y. These two genes are linked to the ovalbumin gene (OV) in the order 5'-X-Y-ovalbumin-3' [Royal, A., Garapin, A., Cami, B., Perrin, F., Mandel, J. L., LeMeur, M., Bregegegre, F., Gannon, F, LePennec, J. P., Chambon, P., & Kourilsky, P. (1979) Nature (London) 279, 125-132]. Both genes contain multiple intervening sequences and share limited sequence homology with the authentic ovalbumin gene but are expressed in oviduct cells at different levels. X and Y hybridization probes were prepared in order to study the expression and the relative hormonal responsiveness of these three genes in chicken oviduct. The sequence specificity of the probes was demonstrated by Southern hybridization assays. Northern hybridization studies using the X and Y gene probes indicated the presence of putative precursor molecules in stimulated oviduct ribonucleic acid preparations, which differ in size from those observed for ovalbumin. R0t analysis has demonstrated that, similar to the ovalbumin gene, the level of X and Y gene transcripts is increased by the steroid hormone estrogen, but to varying degrees. The extent of hormonal responsiveness of the three closely related genes is in the order (normalized) relative to ovalbumin of OV:Y:X congruent to 100:10:1. Pulse-labeling studies of these three closely linked genes suggest that in estrogen-stimulated oviduct, the markedly different steady-state levels of the X, Y, and ovalbumin gene transcripts reflect their differential transcription rates.
A New Fluidized Bed Bioreactor Based on Diversion-Type Microcapsule Suspension for Bioartificial Liver Systems (2016)

A fluidized bed bioreactor containing encapsulated hepatocytes may be a valuable alternative to a hollow fiber bioreactor for achieving the improved mass transfer and scale-up potential necessary for clinical use. However, a conventional fluidized bed bioreactor (FBB) operating under high perfusion velocity is incapable of providing the desired performance due to the resulting damage to cell-containing microcapsules and large void volume. In this study, we developed a novel diversion-type microcapsule-suspension fluidized bed bioreactor (DMFBB). The void volume in the bioreactor and stability of alginate/chitosan microcapsules were investigated under different flow rates. Cell viability, synthesis and metabolism functions, and expression of metabolizing enzymes at transcriptional levels in an encapsulated hepatocyte line (C3A cells) were determined. The void volume was significantly less in the novel bioreactor than in the conventional FBB. In addition, the microcapsules were less damaged in the DMFBB during the fluidization process as reflected by the results for microcapsule retention rates, swelling, and breakage. Encapsulated C3A cells exhibited greater viability and CYP1A2 and CYP3A4 activity in the DMFBB than in the FBB, although the increases in albumin and urea synthesis were less prominent. The transcription levels of several CYP450-related genes and an albumin-related gene were dramatically greater in cells in the DMFBB than in those in the FBB. Taken together, our results suggest that the DMFBB is a promising alternative for the design of a bioartificial liver system based on a fluidized bed bioreactor with encapsulated hepatocytes for treating patients with acute hepatic failure or other severe liver diseases.
Integrated lifing analysis of a film-cooled turbine blade (2001)

A method to predict gas turbine component life based on engine performance analysis is demonstrated on a hot section gas turbine component. The mechanical and thermal loading of the first stage high pressure turbine rotor blade of the F100-PW-220 engine, one of the most severely loaded components in the engine, is analyzed and a life assessment is performed. For this analysis, engine performance history is obtained from in-flight monitored engine parameters and flight conditions and downloaded for processing by a tool integrating a number of software tools and models. Data acquisition is performed by the FACE system installed in a large number of RNLAF F-16 fighter aircraft. Data then is processed by a thermodynamical engine system model, calculating gas properties like pressure and temperature at the required station in the engine. A computational fluid dynamics model, including the blade film cooling, is used to calculate the heat transfer to the blade. A thermal finite element model calculates the temperature distribution in the component and the stress distribution is obtained with a structural finite element analysis. Finally a life consumption model is used to determine the creep and fatigue damage accumulation in the component. The tool has significant potential to enhance on-condition maintenance and optimize aircraft operational use.
p38 Mitogen-Activated Protein Kinase Mediates the Fas-Induced Mitochondrial Death Pathway in CD8<sup>+</sup> T Cells (2006)

The p38 mitogen-activated protein kinase (MAPK) signaling pathway can be activated by a variety of stress stimuli such as UV radiation and osmotic stress. The regulation and role of this pathway in death receptor-induced apoptosis remain unclear and may depend on the specific death receptor and cell type. Here we show that binding of Fas ligand to Fas activates p38 MAPK in CD8+ T cells and that activation of this pathway is required for Fas-mediated CD8+ T-cell death. Active p38 MAPK phosphorylates Bcl-xL and Bcl-2 and prevents the accumulation of these antiapoptotic molecules within the mitochondria. Consequently, a loss of mitochondrial membrane potential and the release of cytochrome c lead to the activation of caspase 9 and, subsequently, caspase 3. Therefore, the activation of p38 MAPK is a critical link between Fas and the mitochondrial death pathway and is required for the Fas-induced apoptosis of CD8+ T cells.
Treatment of statin adverse effects with supplemental Coenzyme Q<sub>10</sub> and statin drug discontinuation (2005)

Fifty consecutive new cardiology clinic patients who were on statin drug therapy (for an average of 28 months) on their initial visit were evaluated for possible adverse statin effects (myalgia, fatigue, dyspnea, memory loss, and peripheral neuropathy). All patients discontinued statin therapy due to side effects and began supplemental CoQ(10) at an average of 240 mg/day upon initial visit. Patients have been followed for an average of 22 months with 84% of the patients followed now for more than 12 months. The prevalence of patient symptoms on initial visit and on most recent follow-up demonstrated a decrease in fatigue from 84% to 16%, myalgia from 64% to 6%, dyspnea from 58% to 12%, memory loss from 8% to 4% and peripheral neuropathy from 10% to 2%. There were two deaths from lung cancer and one death from aortic stenosis with no strokes or myocardial infarctions. Measurements of heart function either improved or remained stable in the majority of patients. We conclude that statin-related side effects, including statin cardiomyopathy, are far more common than previously published and are reversible with the combination of statin discontinuation and supplemental CoQ(10). We saw no adverse consequences from statin discontinuation.
Modulation of the tumor vasculature functionality by ionizing radiation accounts for tumor radiosensitization and promotes gene delivery (2002)

The ultimate goal of radiotherapy is to induce irreversible damages in genetically unstable, fast-growing cancer cells while minimizing the cytotoxic effects on host tissues. The satus of the tumor vasculature is particular because it is located within the tumor but mostly arises from host cells. The aim of this study was to characterize the effects of low-dose irradiation on the function of endothelial cells lining tumor vessels. Using isolated arterioles mounted on a pressure myograph, we first documented that the nitric oxide (NO)-mediated vasorelaxation that was defective in tumor vessels was completely restored following local tumor irradiation. Immunoblot analyses revealed that this was attributable to an increase in the abundance of the endothelial NO synthase while the expression of its physiological inhibitor, caveolin-1, was reduced. We further showed that the potentiation of the NO-dependent pathway induced a marked increase in tumor blood flow and oxygenation that determined the higher sensitivity of the tumor to further irradiation. Finally, we documented that the NO-mediated effects of irradiation on the tumor vasculature increased the delivery and expression of a reporter gene into the tumor. Thus, low-dose irradiation of endothelial cells within a tumor is a key determinant of the effectiveness of radiotherapy and may offer a new strategy to increase gene and/or drug delivery to the tumor.
Characterization of Pharmaceutical Solvates by Combined Thermogravimetric and Infrared Analysis (1997)

The combined physical analytical technique of thermogravimetric and infrared analysis (TG/IR) is described for the investigation of pharmaceutical solids. TG/IR provides an unequivocal identification of the volatile content of a pharmaceutical solid. In the case of pharmaceutical solvates, TG/IR provides identification of the evolved gas from the crystalline solid. Variable temperature X-ray diffraction and differential scanning calorimetry techniques provide the required information to ascertain whether the evolved gas was due to a solvent incorporated into the crystal lattice or physically adsorbed onto the solid. This work illustrates three examples of TG/IR as utilized in a multidisciplinary approach to the physical characterization of pharmaceutical solids.
유전 및 육종 ; 유전자 지문을 이용한 한국 재래계의 식별 (1994)

This study was conducted to genetically identify chicken breeds, especially the Korean Native Chickens (KNC). Genomic DN.A was extracted from live breeds of chickens, including KNC, and digested with the restriction enzyme, Hae III. DNA fingerprinting was applied to the digested DNA using the single stranded bacteriophage M13 DNA as a probe. There were 6 to 26 hypervariable polymorphic bands, between 0.5 and 8 Kb, in each lane. KNC genomic DNA contained 3 breed-specific bands compared to the other chicken breeds. As the purity determined by phenotypes of KNC increased, these breed-specific bands appeared with higher frequencies. Band shaping ratios among breeds indicated that KNC is closer to an egg-laying breed than a meat type breed. The results indicate that DNA fingerprinting is a powerful tool to identify chicken breeds and to study population genetics. Further studies are necessary to keep and maintain pure KNC using DNA fingerprinting.
Checkpointing memory-resident databases (2003)

A database system is considered in which a main-memory database system holds all data in semiconductor memory, and for recovery purposes a backup copy of the database is maintained in secondary storage. The checkpointer is the component of the crash recovery manager responsible for maintaining the backup copy. Ideally, the checkpointer should maintain an almost-up-to-date backup while interfering as little as possible with the system's transaction processing activities. Several algorithms for maintaining such a backup database are presented and compared using an analytic model. The results show some significant performance differences among the algorithms and illustrate some of the tradeoffs that are available in designing such a checkpointer.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
International Trade and Domestic Environmental Emission: A Computable General Equilibrium Analysis for India (2012)

This paper examines General Equilibrium implications of International Trade and Globalization on social welfare and environmental emission. We have applied Computable General Equilibrium (CGE) modeling as relevant methodology in the same way Shoven and Whalley (1984) has done through construction of Energy/Environmental Social Accounting Matrix (SAM) and CGE model. This paper attempts to investigate the effects of Liberalized Trade on different macroeconomic aspects, energy consumption and Green House Gases (GHG) emission. With the help of an index of Pollution Terms of Trade (PTOT) our research finds that trade and globalization in most of the cases aggravated the problem of GHG emission and has made India 'Pollution Haven'.
Multisensor Integration And Fusion: Issues And Approaches (1988)

Issues concerning the effective integration of multiple sensors into the operation of intelligent systems are presented, and a description of some of the general paradigms and methodologies that address this problem is given. Multisensor integration, and the related notion of multisensor fusion, are defined and distinguished. The potential advantages and problems resulting from the integration of information from multiple sensors are discussed.
Paint skip detector (1990)

A method to automatically detect areas on coated aluminum sheet that were left uncoated due to a process malfunction has been developed. Detection sensitivity approaches a 1/4-inch diameter bare spot on the aluminum sheet moving up to 1,000 ft/mm The coated aluminum sheet exits a curing oven at temperatures near 410°F. At this point in the process, any bare spots on the aluminum sheet have an approximate emissivity of 0.10. The coating increases the emissivity by 0.15 to 0.75 depending on type and thickness. Since the bare sheet has a lower emissivity, a coating skip will produce a sudden drop in radiated energy (apparent temperature) . The magnitude of the drop depends upon the coating skip size, the coating thickness, the sensor spot size and the sensor response speed. A scanning thermal sensor and signal processor collects line scan information. A baseline following threshold is used to detect anomalous incidents. These incidents are tracked from scan to scan in order to define a complete defect. Paint skip size, severity and location (both downweb and crossweb) can be reported.

Design of A Single Band Pentagonal Microstrip Patch Antenna for purpose of Medical Equipment (2019)

In navigational applications, radar, wireless communications, military applications and satellites we require a system that works with low weight, low profile and high gain. The above mentioned applications are possible with microstrip antenna. This paper presents design of a single band pentagonal microstrip patch antenna to improve gain and efficiency with operating frequency of 10.7591 GHz and 11.1806 GHz (purpose of medical equipment).  The idea behind design patch is to decrease the return loss and wider band width by changing the shapes of patch. The proposed antenna consists of a single substrate layer on one side with ground plane on other side. Simulated antenna size has been reduced by 52.64% with an increased frequency ratio. The characteristics features of antenna are investigated on Zealand IE3D simulation software.

Proinflammatory Effects of Bacterial Recombinant Human C-Reactive Protein Are Caused by Contamination With Bacterial Products, Not by C-Reactive Protein Itself (2005)

Intravenous administration to human volunteers of a commercial preparation of recombinant human C-reactive protein (CRP) produced in Escherichia coli was recently reported in this journal to induce an acute phase response of serum amyloid A protein (SAA) and of CRP itself, and to activate the coagulation system. The authors concluded that CRP is probably a mediator of atherothrombotic disease. Here we confirm that this recombinant CRP preparation was proinflammatory both for mouse macrophages in vitro and for mice in vivo, but show that pure natural human CRP had no such activity. Furthermore mice transgenic for human CRP, and expressing it throughout their lives, maintained normal concentrations of their most sensitive endogenous acute phase reactants, SAA and serum amyloid P component (SAP). The patterns of in vitro cytokine induction and of in vivo acute phase stimulation by the recombinant CRP preparation were consistent with contamination by bacterial products, and there was 46.6 EU of apparent endotoxin activity per mg of CRP in the bacterial product, compared with 0.9 EU per mg of our isolated natural human CRP preparation. The absence of any proinflammatory activity in natural CRP for macrophages or healthy mice strongly suggests that the in vivo effects of the recombinant preparation observed in humans were attributable to proinflammatory bacterial products and not human CRP.
Animal Models of Allergic Airways Disease: Where Are We and Where to Next? (2014)

In a complex inflammatory airways disease such as asthma, abnormalities in a plethora of molecular and cellular pathways ultimately culminate in characteristic impairments in respiratory function. The ability to study disease pathophysiology in the setting of a functioning immune and respiratory system therefore makes mouse models an invaluable tool in translational research. Despite the vast understanding of inflammatory airways diseases gained from mouse models to date, concern over the validity of mouse models continues to grow. Therefore the aim of this review is twofold; firstly, to evaluate mouse models of asthma in light of current clinical definitions, and secondly, to provide a framework by which mouse models can be continually refined so that they continue to stand at the forefront of translational science. Indeed, it is in viewing mouse models as a continual work in progress that we will be able to target our research to those patient populations in whom current therapies are insufficient.
Memory Cutback for FP-Tree Approach (2014)

The pattern growth approach of association rule mining is very efficient as avoiding the candidate generation step which was utilized in Apriori algorithm. Here, revisited of the pattern growth approaches are done to improve the performance using different criteria like item search order, conditional database representation and construction approach and tree traversal ways. The header table construction is the first part in almost all the approaches having constant number of dataset items. This research is representing the reduction in overall memory requirement of pattern growth approach by reducing the search space and processor operations time at the header table generation. It is proposed to achieve the memory cutback by only considering the items that are going to be frequent and ignoring the infrequent items at early stage of scan, by considering the boundary. Experimental analysis achieves cutback in memory consumption in the proposed approach Modified FP-Growth (MFP-Growth) compare to FP-Growth and CFP-Growth.
Chemistry of thienopyridines. XXXI. A new synthesis of thieno[3,2‐<i>b</i>]pyridine and studies on direct substitution into its thiophene ring (1984)

Abstract Thieno[3,2‐ b ]pyridine ( 1 ) is synthesized in 65% overall yield for two steps which consist of addition of toluene‐α‐thiol to 2‐ethynylpyridine plus vacuum pyrolysis of the addend ( 7 ). Cis and trans forms of 7 are described. Compound 1 undergoes (a) electrophilic substitution at C‐3 to give chloro, bromo, and iodo derivatives (44–57% yields) and (b) lithiation at C‐2 (to give 1a ). Intermediate 1a is converted into derivatives of 1 with halo (19–48%), formyl (54%), acetyl, and hydroxymethyl (40%) substituents at C‐2. Also described are 2‐cyano and 2,3‐dibromo derivatives of 1 . Structural assignments are based on chemical transformations plus 1 H and 13 C nmr spectral data. The substitution pattern of 1 is compared with predictions made on the bases of analogous ring systems and molecular orbital calculations.
