Microwave Sampling Beamformer—Prototype Verification and Switch Design (2008)

In this study, a four-element prototype of the microwave sampling beamformer structure is constructed and tested. The prototype is composed of the microwave hardware and control hardware. A new compact switch is designed and utilized in the structure. The control circuitry is a four-branch time delay and pulsewidth control circuits along with p-i-n diode drivers. The beamforming structure is designed to have 8-bit phase shifter resolution and 12-bit attenuation resolution. For each antenna element the phase shift and attenuation are controlled through the time delay and pulsewidth of the corresponding pulse train. Different beamforming examples such as beam steering, sidelobe level (SLL) control and null forming are examined with the prototype. It is observed that the structure scans the beams to the proper steering angles. SLL close to -30 dB and nulls deeper than -30 dB are measured.
Effect of E‐Prescribing Systems on Patient Safety (2011)

E-prescribing systems enable electronic transmissions of prescriptions to pharmacies from the provider's office. The promise of e-prescribing in regard to patient safety is reduction in the time gap between point of care and point of service, reduction in medication errors, and improved quality of care. This article will give a brief overview of e-prescribing systems, what is known about these systems and their impact on patient safety, and what challenges remain. For purposes of this article, the term "patient safety" will be used interchangeably with medication errors and adverse drug events. Although there is some evidence that e-prescribing alone and e-prescribing with medication decision support can reduce medication errors, there is also evidence that e-prescribing can be a source of medication errors. The need for more study is particularly relevant and timely, as the Centers for Medicare and Medicaid Services is strongly incentivizing providers to use e-prescribing with medication decision support. Despite concerns about efficiency and dissatisfaction, the majority of providers believe e-prescribing provides for improved patient safety. Limited evidence suggests that e-prescribing with medication decision support can improve patient safety.
Lung Cancer and Arsenic Concentrations in Drinking Water in Chile (2000)

Cities in northern Chile had arsenic concentrations of 860 microg/liter in drinking water in the period 1958-1970. Concentrations have since been reduced to 40 microg/liter. We investigated the relation between lung cancer and arsenic in drinking water in northern Chile in a case-control study involving patients diagnosed with lung cancer between 1994 and 1996 and frequency-matched hospital controls. The study identified 152 lung cancer cases and 419 controls. Participants were interviewed regarding drinking water sources, cigarette smoking, and other variables. Logistic regression analysis revealed a clear trend in lung cancer odds ratios and 95% confidence intervals (CIs) with increasing concentration of arsenic in drinking water, as follows: 1, 1.6 (95% CI = 0.5-5.3), 3.9 (95% CI = 1.2-12.3), 5.2 (95% CI = 2.3-11.7), and 8.9 (95% CI = 4.0-19.6), for arsenic concentrations ranging from less than 10 microg/liter to a 65-year average concentration of 200-400 microg/liter. There was evidence of synergy between cigarette smoking and ingestion of arsenic in drinking water; the odds ratio for lung cancer was 32.0 (95% CI = 7.2-198.0) among smokers exposed to more than 200 microg/liter of arsenic in drinking water (lifetime average) compared with nonsmokers exposed to less than 50 microg/liter. This study provides strong evidence that ingestion of inorganic arsenic is associated with human lung cancer.
Water hammer fracture diagnostics (2014)

A sudden change in flow in a confined system results in the formation of a series of pressure pulses known as a water hammer.Pump shutdown at the conclusion of a hydraulic fracture treatment frequently generates a water hammer, which sends a pressure pulse down the wellbore that interacts with the created fracture before returning towards the surface.This study confirms that created hydraulic fractures alter the period, amplitude, and duration of the water hammer signal.Water hammer pressure signals were simulated with a previously presented numerical model that combined the continuity and momentum equations of the wellbore with a created hydraulic fracture represented by a RCI series circuit.Field data from several multi-stage stimulation treatments were history matched with the numerical model by iteratively altering R, C, and I until an appropriate match was obtained.Equivalent fracture dimensions were calculated from R, C, and I, and were in agreement with acquired micro-seismic SRV.Finally, the obtained R, C, and I values were compared to SRV and production log data.Capacitance was directly correlated with SRV, while resistance was inversely correlated with SRV, and no correlations with production data were observed.
Die Isomerisierung des Linolsäuremethylesters mit Rhodiumkomplexen (1977)

Abstract Die isolierten Doppelbindungen des Linolsäuremethylesters können mit Rhodiumkomplexen und Zinn(II)chlorid‐Dihydrat als Katalysatorsystem konjugiert werden. Die Abhängigkeit der Reaktion von verschiedenen Phosphor‐ und Stickstoffliganden am Rhodium wurde untersucht. Tri‐p‐tolylphosphin als Ligand ergab den aktivsten Katalysator, der auch noch bei 25°C eine wirkungsvolle Isomerisierung bewirkt.
Supercritical Fluid Extraction (2013)

Supercritical fluid extraction (SFE) is a mass transfer process under pressure and temperature conditions above the critical point of the solvent. The term “supercritical fluid” refers to any substance that is in an aggregated state at pressures and temperatures higher than the critical temperature and pressure. SFE can be applied to systems on various scales, from the laboratory scale to the pilot plant scale, through to the industrial scale. The chapter provides several examples of industrial applications and details of different industrial plants that use supercritical technology. The main important applications of extraction using solvents under supercritical conditions are the extraction, refinement and fractionation of edible oils, fats, and waxes. The extraction process for solid substances primarily consists of two stages, the extraction and the separation of the product from the solvent. The design and modeling of the process is centered on the extraction stage.
Untargeted Metabolomics (2010)

Along with genes and proteins, metabolites play important roles in sustaining life. Their functions include "primary" functions in metabolism and energy storage, as well as "secondary" functions in cell-to-cell signaling, metal acquisition, and virulence. There remains much to be learned about the in vivo roles of metabolites. Approaches that accelerate measurement of metabolite levels directly from cells and tissues should increase our understanding of the diverse roles of metabolites and potentially lead to discovery of novel metabolites and metabolic pathways. Metabolomics is an important comparative tool to study global metabolite levels in samples under various conditions. In this unit, the steps needed to perform a mass spectrometry (MS)--based untargeted metabolomics experiment using bacterial supernatants are detailed. In contrast to a targeted metabolomics experiment, which measures ions from known metabolites, an untargeted metabolomics experiment registers all ions within a certain mass range, including ions belonging to structurally novel metabolites. The protocols in this unit describe the conditions necessary for analyzing hydrophobic metabolites and provide an example of how to structurally characterize a novel metabolite.
Polymerisation with Solid Phosphoric Acid Catalyst (1951)

The mechanisms contributing to organ injury in hypertension have been incompletely defined. The thymus gland of the spontaneously hypertensive rat (SHR) shows significant atrophy at the age of 15 wk compared with its normotensive control, the Wistar-Kyoto rat (WKY). The aim of the present study was to examine the thymus of SHR for evidence of DNA nicking as one of the mechanisms for thymic atrophy. SHR and WKY were subjected to adrenalectomy or sham surgery at 12 wk and studied at 15 wk. Adrenalectomy served to normalize the blood pressure in the SHR. DNA nicking was detected by in situ nick-end labeling (ISEL) of fixed tissue sections. Tissue sections were treated with proteolysis, and terminal deoxyribonucleotidyl transferase was used to incorporate biotinylated deoxynucleotides into DNA nick end in situ. Separately, DNA fragmentation was evaluated by measuring the level of released mono- and oligonucleosomes to the cytoplasm. A higher number of thymic ISEL-positive cells and a higher level of cytoplasmic mono- and oligonucleosomes were observed in SHR than in WKY. After adrenalectomy the enhanced level of ISEL and cytoplasmic mono- and oligonucleosomes in SHR was reduced to the level in WKY. Dexamethasone treatment (0.05 mg. kg-1. day-1) in WKY serves to decrease the thymus weight and significantly elevate the level of mono- and oligonucleosomes. Thus increased DNA fragmentation represents one of the mechanisms associated with thymic atrophy, a feature that reflects immune suppression in SHR.

Platelet-Derived Growth Factor Mediates Angiotensin II-Induced DNA Synthesis in Vascular Smooth Muscle Cells (1997)

In order to elucidate the mechanism of angiotensin II (ANG II)-induced proliferation in vascular smooth muscle cells in culture, growth rates and 3H-thymidine incorporation into DNA in response to ANG II treatment were examined in cultured rat aortic smooth muscle cells. ANG II-treated and control cells were exposed to the ANG II receptor antagonists [Sar1, Val5, Ala8]-ANG II (Sar) and DUP753 and to antibody against platelet-derived growth factor (PDGF). In growing cells, ANG II acted as a moderate mitogen, inducing an increase in growth rate during the first two days of treatment. ANG II induced a marked increase in 3H-thymidine incorporation in cultured vascular smooth muscle cells. The effect was blocked by the ANG II inhibitors Sar and DUP753 and by the PDGF antibody. ANG II was able to stimulate vascular smooth muscle growth in cell culture. The effect seemed to be mediated, at least in part, by PDGF. These results are in agreement with a possible role of ANG II in promoting vascular growth in physiological and/or pathological situations.
Fusion of Median and Bilateral Filtering for Range Image Upsampling (2013)

We present a new upsampling method to enhance the spatial resolution of depth images. Given a low-resolution depth image from an active depth sensor and a potentially high-resolution color image from a passive RGB camera, we formulate it as an adaptive cost aggregation problem and solve it using the bilateral filter. The formulation synergistically combines the median and bilateral filters thus it better preserves the depth edges and is more robust to noise. Numerical and visual evaluations on a total of 37 Middlebury data sets demonstrate the effectiveness of our method. A real-time high-resolution depth capturing system is also developed using commercial active depth sensor based on the proposed upsampling method.
The simulation of molecular weight distributions in polyreaction kinetics by discrete Galerkin methods (1996)

Abstract This article describes the development of a comprehensive solver for the differential equations arising from the modeling of molecular weight distributions in polyreactions. Based on a series of numerical developments, the software package P REDICI combines new directions in mathematics, chemical computing and implementation. The algorithm is based on a so‐called discrete Galerkin h‐p‐method, which allows the efficient treatment of numerous polymerization reaction types. The abilities of the new concept are demonstrated on challenging examples.
Interspecific hybridization between the tetraploid Chrysanthemum nankingense and Ch. grandiflorum 'Zhongshanzixing' and the genetic performance of their F1 hybrids. (2010)

【Objective】 The interspecific hybridization barrier between cultivated chrysanthemum and diploid wild species were overcome by doubling chromosome,in order to transfer excellent traits or genes of the diploid wild species into chrysanthemum,broaden the gene pool in chrysanthemum,and achieve novel germplasm.【Method】 Artificial hybridizations were made between the diploid and tetraploid of Chrysanthemum nankingense(♂) and cultivated chrysanthemum(Ch.grandiflorum ‘Zhongshanzixing’)(♀).Cytology analysis was used for hybrids identification and some characters of the hybrids were analyzed.【Result】 Pollen viability of the diploid and tetraploid were higher and the pollen grains could germinate on the stigma of Ch.grandiflorum ‘Zhongshanzixing’ well.But no seed was obtained in the combination between the diploid of Ch.nankingense and Ch.grandiflorum ‘Zhongshanzixing’ while a number of interspecific hybrids were obtained by crossing tetraploid Ch.nankingense with Ch.grandiflorum ‘Zhongshanzixing’.The chromosome number of Ch.grandiflorum ‘Zhongshanzixing’,tetraploid of Ch.nankingense and their hybrids were 54,36,and 45,respectively.The chromosome commonest configurations at metaphaseⅠ per pollen mother cell in Ch.grandiflorum ‘Zhongshanzixing’,tetraploid Ch.nankingense and their hybrids were 27Ⅱ,1.70Ⅰ+13.23Ⅱ+0.03Ⅲ+ 1.90Ⅳ and 5.32Ⅰ+13.84Ⅱ+2.79Ⅳ+0.16Ⅵ,mainly with bivalent.Plant height,leaf width,petiole length of hybrids were significantly positive in mid-parent heterosis of hybrids,while their internode length,leaf index,inflorescence diameter,floral disk diameter,and floret number were significantly negative in mid-parent heterosis.【Conclusion】 Doubling the chromosome of Ch.nankingense could overcome the distant hybridization barrier with the cultivated chrysanthemum.

Consensus Recommendations for Gastric Emptying Scintigraphy: A Joint Report of the American Neurogastroenterology and Motility Society and the Society of Nuclear Medicine (2008)

This consensus statement from the members of the American Neurogastroenterology and Motility Society and the Society of Nuclear Medicine recommends a standardized method for measuring gastric emptying (GE) by scintigraphy. A low-fat, egg-white meal with imaging at 0, 1, 2, and 4 h after meal ingestion, as described by a published multicenter protocol, provides standardized information about normal and delayed GE. Adoption of this standardized protocol will resolve the lack of uniformity of testing, add reliability and credibility to the results, and improve the clinical utility of the GE test.
Development of Super-Resolution Microscopy—Application of Laguerre-Gaussian Beam to Microscopy— (2009)

We developed super-resolution microscopy using the fluorescence depletion process. To verify the principle of this microscopy, we measured fluorescence images of micro-beads, i.e the point-spread function (PSF). It was found that the FWHM of PSF becomes smaller than 110 nm. The results show that proposed microscopy can provide a sufficient spatial resolution to overcome the diffraction limit. In microscopy, the Laguerre-Gaussian beam with a zero center singularity plays an important role and determines performance of microscopy. We introduce our proposed technique, including formation about a Laguerre-Gaussian beam tightly focused by a high-NA microscope objective lens.
Predicting Coronary Heart Disease in Middle-Aged and Older Persons (1977)

Of 1,025 men and 1,445 women, aged 49 to 82 years, who were free of coronary heart disease (CHD), 79 men and 63 women subsequently had CHD. Using a risk function based on cholesterol in the high density and low density lipoproteins, systolic blood pressure, left ventricular hypertrophy, and diabetes, less than 2% of the subsequent CHD cases were found in the lowest decile of risk, whereas 25% of the cases for men and 37% for women were found in the highest decile. Predictability held for each specific age group. This predictability was at least as good as that obtained by the usual CHD risk profile at younger ages.
Retiming and resynthesis: optimizing sequential networks with combinational techniques (1991)

Sequential networks contain combinational logic blocks separated by registers. Application of combinational logic minimization techniques to the separate logic block results in improvement that is restricted by the placement of the registers; information about logical dependencies between blocks separated by registers is not utilized. Temporarily moving all the registers to the periphery of a network provides the combinational logic minimization tools with a global view of the logic. A technique is proposed for optimizing a sequential network by moving the registers to the boundary of the network using an extension of retiming, resynthesizing the combinational logic between the registers using existing logic minimization techniques, and replacing the registers throughout the network using retiming algorithms.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

비방사적 맘퀴스트 지수에 의한 총요소생산성 변화와 결정요인 분석: 전북지역전략산업을 중심으로 (2015)

In this paper, we analyses the total factor productivity change and its determinants in Jeonbuk``s regional strategic industry during the period of 2001-2010. The paper follows a two-stage procedure. In the first-stage, using the non-radial and non-oriented Malmquist productivity index, the total factor productivity change is measured and decomposed into technical efficiency and technological change components. In the second-stage, we use fixed and random effects panel models to analyze the determinants of total factor productivity change. The empirical findings suggest that Jeonbuk``s regional strategic industry has exhibited total factor productivity growth mainly attributed to the technological progress rather than the improvement in efficiency. This implies that Jeonbuk``s regional strategic industry still needs to further strengthen technological innovation and improve production efficiency simultaneously. The findings also suggest that the determinants of total factor productivity change are industry specific, which implies that some of the determinants exert different influences across industries. From the findings of the current study, it is proposed that future studies should include other relevant variables which best explain productivity changes.
Regulation of expanded polyglutamine protein aggregation and nuclear localization by the glucocorticoid receptor (2000)

Spinobulbar muscular atrophy and Huntington's disease are caused by polyglutamine expansion in the androgen receptor and huntingtin, respectively, and their pathogenesis has been associated with abnormal nuclear localization and aggregation of truncated forms of these proteins. Here we show, in diverse cell types, that glucocorticoids can up- or down-modulate aggregation and nuclear localization of expanded polyglutamine polypeptides derived from the androgen receptor and huntingtin through specific regulation of gene expression. Wild-type glucocorticoid receptor (GR), as well as C-terminal deletion derivatives, suppressed the aggregation and nuclear localization of these polypeptides, whereas mutations within the DNA binding domain and N terminus of GR abolished this activity. Surprisingly, deletion of a transcriptional regulatory domain within the GR N terminus markedly increased aggregation and nuclear localization of the expanded polyglutamine proteins. Thus, aggregation and nuclear localization of expanded polyglutamine proteins are regulated cellular processes that can be modulated by a well-characterized transcriptional regulator, the GR. Our findings suggest approaches to study the molecular pathogenesis and selective neuronal degeneration of polyglutamine expansion diseases.
