Cardiological Aspects of Growth Hormone and Insulin-like Growth Factor-I (1997)

In recent years it has been demonstrated that both GH deficiency and excess include in their advanced clinical manifestations an impaired cardiovascular function, which may reduce life expectancy. This observation has allowed the investigation of the role played by the GH/IGF-I axis on cardiac structure and function. In particular, several recent experimental and clinical studies support the evidence implicating GH and/or IGF-I in the regulation of heart development. Acromegalic cardiomyopathy is characterized by myocardial hypertrophy with interstitial fibrosis, lymphomononuclear infiltration and areas of monocyte necrosis which often result in increased right and left ventricular mass and concentric hypertrophy. Conversely, patients with childhood or adulthood-onset GH deficiency (GHD) have a reduced left ventricular mass and ejection fraction and the indexes of left ventricular systolic function remained markedly depressed during exercise. In addition, a significant increase in the thickness of the vascular intima-media wall and a higher number of atheromatous plaques have been reported. These abnormalities of the cardiovascular system are partially reversed after normalization of GH and IGF-I levels, by octreotide in acromegaly or after GH replacement therapy in GHD patients. The evidence that GH is able to increase cardiac mass suggested its use in the treatment of idiopathic dilated cardiomyopathy. In a recent study on such patients, the administration of rhGH was demonstrated to increase myocardial mass and to reduce the size of the left ventricular chamber, resulting in an improvement in hemodynamics, myocardial energy metabolism and clinical status. These promising results might open a new field for GH treatment.
Robust and self-adaptive background extraction in video object change detection (2003)

Background subtraction is widely used for the detection of objects moving against a background in video. Moving objects are detected by comparing the current image with the extracted background image (BI). The BI is constructed using a single or several frames without moving foreground object in the scene. The pixel in BI is updated by the current pixel value if this pixel is determined to be part of the background during the subtraction process. The drawback of this approach is the requirement of the establishment of a background image prior to the detection; otherwise any object that appears in the first frame is detected as “moving object” through the whole sequence. An even more serious problem occurs when there is a sudden change in the background, such as a light being turned on or off, or a newly arrived “still” object. As long as the pixel value change is larger than the threshold, the “still” object after the sudden change will not be included in the background image and hence it will appear as a moving object in the following frames. To avoid these problems, we propose an approach in which a second updated background image, BI<sub>2</sub>, is stored. BI<sub>2</sub> is initially constructed from the first frame detected and then updated through the detection processes with criteria different to that used in updating BI. The pixels in BI2 are updated if they have been determined as background pixels by comparing the difference between the current and previous frames. By using this method, the “still” objects are not falsely detected as moving objects. After a few frames, the “still” objects are updated into the background image BI<sub>2</sub>. BI<sub>2</sub> is then incorporated into the background image BI. Moving objects are then subtracted from the modified background image BI and the “still” objects are eliminated.
An autonomous robotic system for load transportation (2009)

This paper presents an overview of an autonomous robotic system for material handling. The system is being developed by extending the functionalities of traditional AGVs to be able to operate reliably and safely in highly dynamic environments. Traditionally, the reliable functioning of AGVs relies on the availability of adequate infrastructure to support navigation. In the target environments of our system, such infrastructure is difficult to setup in an efficient way. Additionally, the location of objects to handle are unknown, which requires runtime object detection and tracking. Another requirement to be fulfilled by the system is the ability to generate trajectories dynamically, which is uncommon in industrial AGV systems.
Complex I deficiency is Associated with 3243G:C Mitochondrial DNA in Osteosarcoma Cell Cybrids (1996)

143B.206 ρ° cells were repopulated with mitochondria from a MELAS patient harbouring a mixture of 3243G:C and 3243A:T mitochondrial DNA. A number of biochemical assays were performed on selected cybrids with various proportions of the two types of mitochondrial DNA. These assays revealed a marked decrease in oxygen consumption with pyruvate, a complex I substrate, in cybrids containing 60% to 90% 3243G:C mitochondrial DNA. Moreover, these cybrids showed decreased synthesis of a number of polypeptides in a mitochondrial <it>in vitro</it> translation assay. A cybrid line with a very high level of 3243G:C mitochondrial DNA (95%) had additional deficiencies in complexes III and IV and there was a marked generalised decrease in mitochondrial translation in this cybrid. The observation of complex I deficiency is consistent with previously reported enzymatic measurements of muscle homogenates from MELAS patients with the 3243G:C mutation.
Real-time signal processing for fetal heart rate monitoring (2003)

An algorithm based on digital filtering, adaptive thresholding, statistical properties in the time domain, and differencing of local maxima and minima has been developed for the simultaneous measurement of the fetal and maternal heart rates from the maternal abdominal electrocardiogram during pregnancy and labor for ambulatory monitoring. A microcontroller-based system has been used to implement the algorithm in real-time. A Doppler ultrasound fetal monitor was used for statistical comparison on five volunteers with low risk pregnancies, between 35 and 40 weeks of gestation. Results showed an average percent root mean square difference of 5.32% and linear correlation coefficient from 0.84 to 0.93. The fetal heart rate curves remained inside a +/- 5-beats-per-minute limit relative to the reference ultrasound method for 84.1% of the time.

Electronic healthcare: issues and challenges (2006)

The shift in the nation's attention, resources and interest toward internet-related healthcare activities, often called 'e-health', is dramatic and a most significant development in the healthcare environment. E-health, while exciting and promising, also presents new challenges, particularly in regard to acceptable standards, choice of technologies, overcoming traditional jurisdictional boundaries, up-front investment and privacy and confidentiality. This paper presents e-health architecture and various issues and challenges that need to be resolved before e-health becomes commonplace.

Use of complementary and alternative medical therapies among racial and ethnic minority adults: results from the 2002 National Health Interview Survey. (2005)

Excluding prayer, Hispanics and non-Hispanic blacks used CAM less frequently than non-Hispanic whites and were less likely to disclose their use to their healthcare provider. Further research is needed to improve our understanding of the disparities in CAM use.
Solid-state decomposition of silicon carbide for growing ultra-thin heteroepitaxial graphite films (2002)

Using grazing-incidence x-ray diffraction and scanning tunneling microscopy (STM), we show that the thermal decomposition of an electronic-grade wafer of 6H-SiC after annealing at increasing temperatures TA between 1080 and 1320 °C leads to the layer-by-layer growth of unconstrained, heteroepitaxial single-crystalline graphite. The limited width of the in-plane diffraction rod profiles of graphite reveals large terraces, with an average size larger than 200 Å and a very small azimuthal disorientation. The overlayer is unstrained and adopts the crystalline parameter of bulk graphite even at the smallest coverage studied, which corresponds to a single graphene plane, as inferred from the flat out-of-plane diffraction profile. By increasing TA, additional graphene planes can be grown below this graphite layer from the solid-state decomposition of SiC, forming the AB stacking of Bernal graphite. A C-rich precursor is evidenced in STM by an intrinsic (6×6) reconstruction made of ordered ring or starlike structures. The resulting epitaxial film is indistinguishable from a bulk graphite single crystal.
Enhanced surface emitting waveguides for visible, monolithic semiconductor laser sources (1990)

By using AlGaAs resonant multilayers embedded in a wave-guide geometry a ten million fold enhancement for surface emitting harmonic generation over a normal GaAs film was obtained. The multilayer system allows compensation for material losses at the harmonic and the use of thick films for efficient coupling of communication fibres to the device. The experimental results agree closely with theory and a monolithic implementation of visible, surface emitting solid state diode lasers is presented for InGaAs, InP and GaAs geometries.
Efficient search procedures for selecting the optimum innovation in stochastic coders (1990)

The authors describe several procedures that simplify the search in stochastic coders, but do not put constraints on the structure of the codewords. The computational efficiency is achieved by moving the search for the best codeword from time domain to another domain where the convolution operation in the linear filter is reduced to a single multiplication operation. A computational reduction by a factor of approximately 20 is achieved, without producing any perceptual degradation of the synthetic speech. The advantages of search procedures in a transform domain are discussed, not only in terms of efficiency, but also to provide better insights into the function of stochastic coders.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

Estimation of electron traps in carbon-60 field-effect transistors by a thermally stimulated current technique (2007)

The authors investigated the influence of O2 and H2O molecules absorbed in carbon-60 (C60) films on their electron trap and n-type field-effect transistor (FET) characteristics. Electron traps in the C60 films were directly measured using a thermally stimulated current (TSC) technique. The TSC results demonstrate that the absorption of O2 and H2O molecules in the C60 films induced an increase in the electron trap concentration, which degrades C60 FET characteristics. By annealing the C60 films at 100°C for 8h, the electron trap concentrations were markedly lowered, enhancing the C60 FET characteristics. An electron mobility of 0.017cm2∕Vs and a current on/off ratio of 106 were observed from the degassed C60 FETs.
[Determination of nifedipine in human plasma by gas chromatography and its pharmacokinetic study]. (1997)

A gas chromatographic method for the determination of nifedipine in human plasma is presented. Nifedipine was extracted into toluene and diazepam was used as the internal standard. Chromatography was performed on an OV-101 fused-silica column by splitless injection with an electron capture detector. The minimal detectable concentration in plasma was 1 ng.ml-1. The standard curve was linear in the range 2-150 ng.ml-1 (gamma = 0.9988). The method has been applied to pharmacokinetic study.
20.3: Optimizing the Balance of Holes and Electrons in Inverted Quantum Dot Light‐Emitting Diodes by Inserting Electron Transportation Barrier Layer (2015)

In this study, the hole‐electron balance of quantum dot lightemitting diodes (QDLED) was tuned in order to achieve efficiency enhancement. This hole‐electron balance optimization was realized by inserting thin barrier layer in the electron transportation layer. Although the current density was slightly sacrificed because of the electron blocking of the barrier layer, the charge balance was improved hence leading to 123% efficiency enhancement.
Flight testing of the Capillary Pumped Loop Flight Experiment (1995)

The Capillary Pumped Loop Flight Experiment (CAPL) employs a passive two-phase thermal control system that uses the latent heat of vaporization of ammonia to transfer heat over long distances. CAPL was designed as a prototype of the Earth Observing System (EOS) instrument thermal control systems. The purpose of the mission was to provide validation of the system performance in micro-gravity, prior to implementation on EOS. CAPL was flown on STS-60 in February, 1994, with some unexpected results related to gravitational effects on two-phase systems. Flight test results and post flight investigations will be addressed, along with a brief description of the experiment design.
The Influence of Hindered Molecular Rotation on the Dielectric Constants of Water, Alcohols, and Other Polar Liquids (1943)

The theory of dielectric polarization of polar liquids is used to calculate the dielectric constants of water and some alcohols. Quasi-rigid coordination models, based upon x-ray structural investigations, are employed in the calculation of a function g which measures the orientational correlation between neighbors in the liquid. It is pointed out that the correlation function g is closely related to the thermodynamic ``abnormality'' of polar liquids.
Methods for Performing Atomic Force Microscopy Imaging of Clay Minerals in Aqueous Solutions (1999)

Abstract Three methods were developed that allow for the imaging of any clay mineral in aqueous solutions with atomic force microscopy (AFM). The methods involve fixing the particles onto special substrates that do not complicate the imaging process, but hold the particles sufficiently so that they do not move laterally or float away during imaging. Two techniques depend on electrostatic attraction under circumneutral pH conditions, between the negatively charged clay particles and the high point of zero charge substrate (either aluminum oxide or polyethyleneimine-coated mica) whereas the third technique depends on adhesion to a thermoplastic film. The first electrostatic technique involves a polished single crystal α-Al 2 O 3 (sapphire) substrate. This was used successfully as a substrate for clay-sized minerals with high permanent layer charge localized on the basal planes (phlogopite and vermiculite) and when the AFM was operated in TappingMode to limit the lateral forces between the probe tip and the particles. However, electrostatic attraction between the sapphire surface and clay minerals such as smectite and kaolinite (low or no permanent layer charge) is not sufficiently strong to adequately fix the particles for imaging. The second electrostatic technique involves a polyethyleneimine-coated mica surface designed to immobilize a larger variety of clay minerals (phlogopite, vermiculite, montmorillonite, and kaolinite), and in this technique weak bonding between the clay and the organic film is also a factor. The third technique, which does not depend on electrostatic attraction, fixes clay particles into the surface of a thermoplastic adhesive called Tempfix. This has proven useful for fixing and imaging relatively large clay particles with well-defined morphology. The Tempfix mount also requires imaging in TappingMode because the Tempfix is relatively soft.

Flame Spray Pyrolysis of Precursors as a Route to Nano‐mullite Powder: Powder Characterization and Sintering Behavior (2001)

The flame spray pyrolysis of alcohol‐soluble precursors allows the synthesis of mullite‐composition nanopowders (average size of ∼60–100 nm) that, when annealed carefully, provide processable nano‐mullite powders. The powders have been characterized using several spectroscopic and microscopy methods, including thermal gravimetric analysis, differential thermal analysis, diffuse reflectance infrared Fourier transform spectroscopy, and transmission electron microscopy. Preliminary studies on the pressureless‐sintering behavior of these powders are presented. Without additives or any efforts to optimize the process, powder compacts could be sintered to relative densities of >90%, with grain sizes of <500 nm at 1600°C.
Low Temperature Epitaxy Growth and Kinetic Modeling of SiGe for BiCMOS Application (2011)

There is an ambition of continuously decreasing thermal budget in CMOS and BiCMOS processing, thus low temperature epitaxy (LTE) (350-650°C) with chemical vapor deposition (CVD) technique in order to have faster process with low cost. One of the growth issues at low temperatures is gas quality where the oxygen and moisture contamination becomes critical for the epilayers quality. If the level amount of contamination is not controlled, the silicon dioxide islands are formed and the oxygen level in the film will be high. This thesis is focused on two different aspects of "LTE". The first focus of this thesis was to identify the effect of contamination on the strain and quality of the SiGe epilayers (prior and during epitaxy). The samples in this study were exposed to different oxygen and moisture partial pressures (2ppb-250 ppm range) at different exposure temperatures (350-650°C). The results revealed that presence of contamination even at low ranges (2-100 ppb) is not negligible and affects the strain. Parameters such as O2 exposure temperature and partial pressure, and SiGe layer’s growth temperature impacted the oxygen level and strain in the films. For oxygen levels below 100 ppb, High Resolution Scanning Microscopy (HRSEM) could not detect very small oxide island. By increasing the O2 partial pressure well above 100 ppb, the oxide islands are saturated at 0.08 μm2. The second focus of this thesis was to model the Si2H6/Ge2H6-based epitaxial growth of SiGe. The model can predict the number of free sites on Si surface, growth rate of Si and SiGe, and the Ge content at low temperature. A good agreement between the model and the experimental data is found. This model can provide the required growth parameters for certain layer profile which is vital to decrease the total number of growth runs for calibration and cause to reduce the total fabrication cost.
