Observation on effect of intermittent oxygen atomization inhalation on heart failure complicated by pulmonary infection (2009)

Objective To observe the effect of intermittent oxygen atomization inhalation on heart failure complicated by pulmonary infection. Methods 120 patients with heart failure complicated by pulmonary infection were randomly divided into two groups, 60 in the observation group and 60 in the control group. Besides the routine drug treatment to eliminate inflammation, cough, sputum, cardiotonic and diuresis, the observation group adopted the intermittent atomization inhalation, but the control group adopted persistent atomization inhalation. The curative effects of the two groups were compared. Results The time used to eliminate sputum, the disappearing time of cough and the time to control infection were significantly shorter in the observation group than those in the control group. Comared to the control group, there were statistical meanigus in respiration, heart rate and blood oxygen saturation in the observation group 2 hrs after atomization inhalation (P<0. 01). There were more side effects in the control group, and the difference had statisticalmeaning ( P < 0. 01 ). Conclusions The intermittent oxygen atomization inhalation can stablize the respiration and heart rate, obviously shorten the time to eliminate inflammation, the disappearing time of cough and the time to control infection, reduce the side effects and improve the therapeutic effect among the patients with heart failure complicated by pulmonary infection.

Fully automatic lesion boundary detection in ultrasound breast images (2007)

We propose a novel approach to fully automatic lesion boundary detection in ultrasound breast images. The novelty of the proposed work lies in the complete automation of the manual process of initial Region-of-Interest (ROI) labeling and in the procedure adopted for the subsequent lesion boundary detection. Histogram equalization is initially used to pre-process the images followed by hybrid filtering and multifractal analysis stages. Subsequently, a single valued thresholding segmentation stage and a rule-based approach is used for the identification of the lesion ROI and the point of interest that is used as the seed-point. Next, starting from this point an Isotropic Gaussian function is applied on the inverted, original ultrasound image. The lesion area is then separated from the background by a thresholding segmentation stage and the initial boundary is detected via edge detection. Finally to further improve and refine the initial boundary, we make use of a state-of-the-art active contour method (i.e. gradient vector flow (GVF) snake model). We provide results that include judgments from expert radiologists on 360 ultrasound images proving that the final boundary detected by the proposed method is highly accurate. We compare the proposed method with two existing state-of- the-art methods, namely the radial gradient index filtering (RGI) technique of Drukker et. al. and the local mean technique proposed by Yap et. al., in proving the proposed method's robustness and accuracy.

Gap-fill type HSQ/ZEP520A bilayer resist process-(II): HSQ island and spacer formation (2008)

Hydrogen silsesquioxane (HSQ) bilayer resist (BLR) processes are attractive to obtain nano-sized features with high aspect ratio by dry-transferring thin e-beam pattern to thick underlayer to strengthen the etch resistance. However, there are drawbacks of high e-beam dosage for HSQ patterning and difficulty in controlling the underlayer resist profile by O2 plasma with anisotropic etching. In this study gap-fill type HSQ/ZEP520A BLR processes were studied to overcome these problems. The advantage of gap-fill type BLR processes is that the dosage for patterning on thick ZEP520A e-beam positive resist is not as high as that for HSQ and the resist profile can be tuned by exposure and development processes without depending on O2 plasma. By gap-filling of HSQ in ZEP520A trench patterns and then stripping ZEP520A by O2 plasma the tone is conversed from trench to line. The gap filling quality attributes include (1) the void size and number of HSQ lines and (2) spacer adhesion on HSQ line edge. Only the non-diluted HSQ solution could completely fill the trench and the HSQ line formed after stripping of ZEP520A. The spacer formed by diluted HSQ is found to be composed of oxide without any ZEP520A-related elements by FTIR analysis. The ZEP520A trench CD monotonically increases with decrease of W/L ratio. The HSQ line CD also follows the same trend. The extension of HSQ in ZEP520A, i.e. HSQ line CD minus ZEP520A trench CD, basically follows the reverse trend. It is therefore concluded that extension of HSQ lines in ZEP520A and HSQ spacers are formed from the diffused HSQ in trench sidewall without any reaction with ZEP520A. Voids were generally observed at the bottom of the HSQ line. Size and quantity of voids are larger for lower W/L ratios, indicating that the voids were formed due to insufficient HSQ volume for gap-filling. Increasing e-beam dose, baking or reflow temperature, and reflow of ZEP520A before HSQ coating could reduce the void formation. Multiple gap-filling with 1:14 diluted HSQ can lead to void-free lines. The HSQ spacer becomes thicker with less diluted HSQ, slower spin speed, reduced ZEP520A development time and HSQ PCB temperature. The smallest HSQ island of 46.3 nm was obtained by two reflows plus HSQ gap filling and baking processes, a significant size for the hardmask of metal island etching or mold of contact-hole nano-imprint for 45 nm node. The width of HSQ spacers is generally within 10-25 nm, potentially applicable to transistor gate patterning in 22 nm node and beyond.
A Feasibility Study for Monitoring Systems of Fatigue Damage to Helicopter Components (1975)

Abstract : The report describes efforts to monitor and record the in-flight operations of UH-1H and CH-47C helicopters for the subsequent assessment of the fatigue damage to their structures, four types of monitoring were investigated: (1) flight condition monitoring, (2) component-load monitoring, (3) mission-type monitoring, and (4) direct monitoring. After the recording systems and corresponding data processing systems were identified for each monitoring type, each type was tested for its technical acceptability and cost-effectiveness. Study results indicated that the flight condition monitoring is best for the UH- 1H and also for the CH-47C provided that the monitoring of gross weight for the latter model becomes technically acceptable.
Automated analysis systems for monitoring, maintenance and control of power systems (2008)

Increased demands on power systems reliability lead to more stringent requirements for power system monitoring, maintenance and control. Introduction of Intelligent Electronic Devices (IEDs) in substations allows more elaborate recording of field data that in turn may be used to enhance the analysis for monitoring, maintenance and control purposes. While the additional data recorded by IEDs provides more information than the classical solutions, the overwhelming amount of data makes manual analysis quite impractical. Automating the analysis becomes a crucial approach for improving reliability. The paper also illustrates how the overall solution may be implemented using various software and communication means. Commercial version of the solution is partially implemented at one of the EPRI member utilities and a fully expanded version is being planned at another.
The properties of epitaxial pure germanium films on silicon substrate (2002)

To fabricate avalanche photodiodes with less multiplication noises based on germanium, the properties of epitaxial Ge films on silicon substrate are studied. Ge layers are grown directly on an Si substrate by using surfactant-mediated epitaxy (SME) in the molecular beam epitaxy (MBE) growth. Transmission electron microscopy (TEM) and double-crystal X-ray diffraction (XRD) are performed. From the results, we can obtained relaxed, pure and high quality Ge layers. The crystal quality of the sample with implanted p-n junction are better than that of the sample with epitaxial p-n junction. Hole mobility determined by Hall measurements reaches almost 300 cm/sup 2//Vs. Properties of sample with an implanted p-n junction are quite good. Reverse breakdown voltage is 50-100 V and forward-conducting voltage is 0.3-0.5 V.
Passive Immunoprophylaxis with Human Monoclonal Antibodies (1992)

Passive immunoprophylaxis with human immunoglobulin has been employed in a number of clinical settings. Normal human serum immunoglobulin (NHSG) can be used to prevent opportunistic infections in immunocompromised patients. However, the antibody titer of NHSG is very low for any specific causative agent, and consequently its prophylactic efficacy is only marginal. Unlike such polyclonal immunoglobulin, monoclonal antibodies (MAbs) have extremely high titers specific to single-antigenic epitopes. Although MAbs have been shown to be very effective for passive immunoprophylaxis in animal studies, most of those MAbs are of rodent origin. When administered to humans, they induce an immune response that not only blocks the antibody activity, but also sometimes results in untoward reactions. Therefore, MAbs of human origin are desired for in vivo administration to humans.
Usefulness of MALDUTOF mass spectrometry of immunoprecipitated serum variant transthyretin in the diagnosis of familial amyloid polyneuropathy (1999)

A matrix-assisted laser desorption ionization/time-of-flight (MALDI/TOF) mass spectrometry (MS) system was used to detect variant transthyretin (TTR) in immunoprecipitated serum TTR molecules obtained from 6 patients with familial amyloid polyneuropathy (FAP) who were already proven not to have ATTR Val30Met. This simple and quick method showed six different patterns of mass spectra of TTR-related immunoprecipitates from these patients, and in each patient the clearly identified characteristic doublet-shaped ion peaks consisted of normal and variant TTR apart from each other peak with a mass difference between them. DNA sequencing confirmed that the patterns of variant TTR corresponded respectively to ATTR Val30Leu, ATTR Phe33Val, ATTR Asp38Ala, ATTR Ser50Arg, ATTR Ala97Gly and ATTR Ala97Ser. ATTR Asp38Ala and ATTR Ala97Ser are previously unknown variants of TTR leading to the development of FAP. ATTR Phe33Val was found in a Chinese FAP patient and ATTR Ala97Ser in a Taiwanese. Serum analysis using immunoprecipitation and MALDI/TOF MS system can provide useful information when investigating FAP patients with diverse types of variant TTR.
Interstitial devices for minimally invasive thermal ablation by high-intensity ultrasound (2007)

Interstitial ultrasound applicators have been proposed for treating deep-seated tumours that cannot be reached with extra-corporeal high-intensity focused ultrasound. In addition, interstitial ultrasound offers several advantages compared with conventional ablation technology (radiofrequency, microwaves, cryotherapy) in terms of penetration, speed of coagulation, ability to direct and control the thermal lesion and compatibility with image monitoring. The ultrasound source is brought as close as possible to the target in order to minimize the effects of attenuation and phase aberration along the ultrasound pathway. The present paper is a review of the interstitial applicators that were described during the last decade in the literature. It is presented in three sections. The technical aspects common to all applicators are first described. For example, most-described applicators are sideview applicators whose active element is water-cooled and operates at rather high frequency (above 3 MHz) in order to promote heating. Then the different potential techniques for monitoring treatment administered by the interstitial route are presented and illustrated through a review of image-guided interstitial thermal ablation. Three major techniques of imaging are used for guiding interstitial treatment: MRI, ultrasound and fluoroscopy. The third section goes in to further detail on diverse described medical applications.
Amino-Terminal Region of the Human Immunodeficiency Virus Type 1 Nucleocapsid Is Required for Human APOBEC3G Packaging (2004)

APOBEC3G exerts its antiviral activity by targeting to retroviral particles and inducing viral DNA hypermutations in the absence of Vif. However, the mechanism by which APOBEC3G is packaged into virions remains unclear. We now report that viral genomic RNA enhances but is not essential for human APOBEC3G packaging into human immunodeficiency virus type 1 (HIV-1) virions. Packaging of APOBEC3G was also detected in HIV-1 Gag virus-like particles (VLP) that lacked all the viral genomic RNA packaging signals. Human APOBEC3G could be packaged efficiently into a divergent subtype HIV-1, as well as simian immunodeficiency virus, strain mac, and murine leukemia virus Gag VLP. Cosedimentation of human APOBEC3G and intracellular Gag complexes was detected by equilibrium density and velocity sucrose gradient analysis. Interaction between human APOBEC3G and HIV-1 Gag was also detected by coimmunoprecipitation experiments. This interaction did not require p6, p1, or the C-terminal region of NCp7. However, the N-terminal region, especially the first 11 amino acids, of HIV-1 NCp7 was critical for HIV-1 Gag and APOBEC3G interaction and virion packaging. The linker region flanked by the two active sites of human APOBEC3G was also important for efficient packaging into HIV-1 Gag VLP. Association of human APOBEC3G with RNA-containing intracellular complexes was observed. These results suggest that the N-terminal region of HIV-1 NC, which is critical for binding to RNA and mediating Gag-Gag oligomerization, plays an important role in APOBEC3G binding and virion packaging.
Resolution-enhanced integral imaging using two micro-lens arrays with different focal lengths for capturing and display (2015)

We proposed a resolution enhanced integral imaging display method using two micro-lens arrays (MLA) with different focal lengths for capturing and display respectively. An elemental image array (EIA) is captured with MLA of focal length of f(1) and a processed EIA is displayed with MLA of focal length of f(2) which is larger than f(1). We enlarge the "effective area" in processed EIA to increase the information obtained by viewer, in other words, enhance the viewing resolution. The two micro-lens arrays for capturing and display are g and mg distant from display device respectively, and we can get m(2) times resolution enhancement.
Phycocyanobilin:Ferredoxin Oxidoreductase ofAnabaena sp. PCC 7120 (2003)

In cyanobacteria, the biosynthesis of the phycobiliprotein and phytochrome chromophore precursor phycocyanobilin is catalyzed by the ferredoxin-dependent enzyme phycocyanobilin:ferredoxin oxidoreductase (PcyA), which mediates an atypical four-electron reduction of biliverdin IXalpha. Here we describe the expression, affinity purification, and biochemical characterization of recombinant PcyA from Anabaena sp. PCC 7120. A monomeric protein with a native M(r) of 30,400 +/- 5,000, recombinant PcyA forms a tight and stable stoichiometric complex with its substrate biliverdin IXalpha. The enzyme exhibits a strong preference for plant type [2Fe-2S] ferredoxins; however, flavodoxin can also serve as an electron donor. HPLC analyses establish that catalysis proceeds via the two electron-reduced intermediate 18(1),18(2)-dihydrobiliverdin, indicating that exovinyl reduction precedes A-ring (endovinyl) reduction. Substrate specificity studies indicate that the arrangement of the A- and D-ring substituents alters the positioning of the bilin substrate within the enzyme, profoundly influencing the course of catalysis. Based on these observations and the apparent lack of a metal or small molecule cofactor, a radical mechanism for biliverdin IXalpha reduction by phycocyanobilin:ferredoxin oxidoreductase is envisaged.
Randomized incremental constructions of three-dimensional convex hulls and planar voronoi diagrams, and approximate range counting (2006)

We present new algorithms for approximate range counting, where, for a specified e > 0, we want to count the number of data points in a query range, up to relative error of e. We first describe a general framework, adapted from Cohen [10], for this task, and then specialize it to two important instances of range counting: halfspaces in R3 and disks in the plane. The technique reduces the approximate range counting problem to that of finding the minimum rank of a data object in the range, with respect to a random permutation of the input.A major technical step in our analysis, which we believe to be of independent interest, is a bound of O(n log n) on the expected complexity of the overlay of all the Voronoi faces that are generated during a randomized incremental construction of the Voronoi diagram of n points in the plane. The same bound holds for the expected complexity of the overlay of all the faces of the minimization diagram of the lower envelope of n planes in R3, or for the expected complexity of the overlay of all the normal (or Gaussian) diagram faces of the convex hull of n points in R3, that are generated during a randomized incremental construction of the lower envelope or of the hull, respectively. All these bounds are tight in the worst case.The first bound leads to an algorithm that, for a query point x ∈ R2, efficiently retrieves the sequence of nearest neighbors of x in P, over the random insertion process. A query takes O(log n) expected time, and the expected storage size is O(n log n). Similarly, the other bounds lead to an algorithm that, for a query direction ω ∈ S2, efficiently retrieves the sequence of the convex hull vertices that are touched by the planes with outward direction ω that support the convex hull during the random insertion process. Again, a query takes O(log n) expected time, and the expected storage size is O(n log n). These algorithms are used as the main component in the approximate range counting technique that we present, for ranges that are halfspaces in R3 or disks in the plane.

An investigation of the structure of furfuryl alcohol polycondensates with infrared spectroscopy (1963)

Furan resins were prepared by the polymerization of furfuryl alcohol with either acid or thermal catalysis. The effect of catalysts, solvents, polymerization time, and atmosphere were studied for their effects upon the chemical structure of the polymer produced. It has been found that, regardless of the technique employed, the resins contained appreciable amounts of ketonic species. Examination of the infrared spectrum of these resins indicated that the relative amount of ketonic material to furan ring–containing species was the same, regardless of the resin viscosity. It is proposed that the ketonic species arise during the polymerization by ring–opening of the furan unit, forming γ-diketone functional systems as part of the polymer unit. The resins were separated into crude fractions by vacuum distillation, base extraction, and fractional precipitation. From heat-catalyzed resins a lactonic component identified as 5-hydroxy-3-pentenoic γ-lactone was isolated. The curing of furan resins in nitrogen was shown to proceed through further condensation of furan methylol groups with furan rings having an available α-hydrogen. β-Hydrogen crosslinking reactions were not supported by infrared examination of the curing process.
An Improved Faster R-CNN for Same Object Retrieval (2017)

An improved faster region-based convolutional neural network (R-CNN) [same object retrieval (SOR) faster R-CNN] is proposed to retrieve the same object in different scenes with few training samples. By concatenating the feature maps of shallow and deep convolutional layers, the ability of Regions of Interest (RoI) pooling to extract more detailed features is improved. In the training process, a pretrained CNN model is fine-tuned using a query image data set, so that the confidence score can identify an object proposal to the object level rather than the classification level. In the query process, we first select the ten images for which the object proposals have the closest confidence scores to the query object proposal. Then, the image for which the detected object proposal has the minimum cosine distance to the query object proposal is considered as the query result. The proposed SOR faster R-CNN is applied to our Coke cans data set and three public image data sets, i.e., Oxford Buildings 5k, Paris Buildings 6k, and INS 13. The experimental results confirm that SOR faster R-CNN has better identification performance than fine-tuned faster R-CNN. Moreover, SOR faster R-CNN achieves much higher accuracy for detecting low-resolution images than the fine-tuned faster R-CNN on the Coke cans (0.094 mAP higher), Oxford Buildings (0.043 mAP higher), Paris Buildings (0.078 mAP higher), and INS 13 (0.013 mAP higher) data sets.
Influence of the interfacial oxide on titanium silicide formation by rapid thermal annealing (1984)

The interaction of titanium films with single crystal silicon during rapid thermal annealing (RTA) has been studied by Auger analysis and SEM. The diffusion of silicon in titanium to form a silicide has been investigated as a function of the thickness of the interfacial silicon dioxide between the film and the substrate. For a clean interface the diffusion is initiated at lower temperatures, approximately 600 °C. Ion beam mixing of the interface caused by the implantation of heavy ions, such a arsenic, through the titanium film helps to render the interfacial oxide ineffective and thereby facilitates Si diffusion into the film. The presence of the interfacial oxide has been shown to affect the smoothness of the final silicide layer and the silicide–silicon interface. Silicide films produced from ion-mixed films have been found to have smoother surfaces and interfaces than nonion-mixed samples. Application of ion-mixed films to devices has been studied.
