The Application of an Ultrasound Tomography Algorithm in a Novel Ring 3D Ultrasound Imaging System (2018)

Currently, breast cancer is one of the most common cancers in women all over the world. A novel 3D breast ultrasound imaging ring system using the linear array transducer is proposed to decrease costs, reduce processing difficulties, and improve patient comfort as compared to modern day breast screening systems. The 1 × 128 Piezoelectric Micromachined Ultrasonic Transducer (PMUT) linear array is placed 90 degrees cross-vertically. The transducer surrounds the mammary gland, which allows for non-contact detection. Once the experimental platform is built, the breast model is placed through the electric rotary table opening and into a water tank that is at a constant temperature of 32 °C. The electric rotary table performs a 360° scan either automatically or mechanically. Pulse echo signals are captured through a circular scanning method at discrete angles. Subsequently, an ultrasonic tomography algorithm is designed, and a horizontal slice imaging is realized. The experimental results indicate that the preliminary detection of mass is realized by using this ring system. Circular scanning imaging is obtained by using a rotatable linear array instead of a cylindrical array, which allows the size and location of the mass to be recognized. The resolution of breast imaging is improved through the adjustment of the angle interval (>0.05°) and multiple slices are gained through different transducer array elements (1 × 128). These results validate the feasibility of the system design as well as the algorithm, and encourage us to implement our concept with a clinical study in the future.
Synthesis and analysis of an industrial embedded microcontroller (2002)

This paper presents a case study of synthesis and analysis of the industrial embedded microcontroller HT48100, using the hardware/software co-synthesis tool (PIPER-II) for microcontrollers/microprocessors. The synthesis tool accepts as input the instruction set architecture (behavioral) specification, and produces as outputs the pipelined RTL designs with their simulators, and the reordering constraints which guide the assembler how to generate code for the synthesized designs. The study shows that the synthesis approach was able to help the original design team to evaluate their design quality, analyze the architectural properties and explore possible architectural improvements and their impacts in both hardware and software. Feasible future upgrade for the microcontroller family is identified by the study. Further cooperation with the design team has been undertaken to integrate the synthesis methodology into their design flow.

MediterrAsian Diet Products That Could Raise HDL-Cholesterol: A Systematic Review (2016)

<i>Background</i>. High HDL-cholesterol (HDL-C) values are negatively correlated with cardiovascular diseases. This review analyses the effect of the supplementation with various Mediterranean diet products (artichoke, bergamot, and olive oil) and Asian diet products (red yeast rice) on the HDL-C value in dyslipidemic subjects. <i>Methods</i>. A systematic review has been done involving all the English written studies published from the 1st of January 1958 to the 31st of March 2016. <i>Results</i>. The results of this systematic review indicate that the dietary supplementation with red yeast rice, bergamot, artichoke, and virgin olive oil has promising effects on the increase of HDL-C serum levels. The artichoke leaf extract and virgin olive oil appear to be particularly interesting, while bergamot extract needs further research and the effect of red yeast rice seems to be limited to patients with previous myocardial infarction. <i>Conclusions</i>. Various MediterrAsian diet products or natural extracts may represent a potential intervention treatment to raise HDL-C in dyslipidemic subjects.

Accessibility of Responsive End-Caps in Films Composed of Stimuli-Responsive, Depolymerizable Poly(phthalaldehydes) (2013)

Polymers that are capable of depolymerizing completely from head-to-tail upon cleavage of an end-cap from the terminus of the polymer have emerged recently as a new strategy for creating stimuli-responsive solid-state materials with amplified responses. In theory, solid-state materials made from these polymers will respond most efficiently to a stimulus in solution when the polymer end-caps are displayed into solution at the solid–liquid interface, rather than being buried in the solid-state material. This article defines two strategies for increasing the likelihood that end-caps are displayed at this interface. A microscale-pump made from films of depolymerizable poly(phthalaldehyde) serves as a test system for evaluating the location of end-caps in the films. By measuring the flow rate initiated by depolymerization of the polymers within the films, we determined that both the polymer length and hydrophilicity of the end-caps affect the density of end-caps at the solid–liquid interface.
Prediction of Road Accident Severity Using the Ordered Probit Model (2014)

The ordered probit model is used to examine the contribution of several factors to the injury severity faced by motor-vehicle occupants involved in road accidents. The estimated results suggest that motor-vehicle occupants travelling in light-vehicles, at two-way roads, and on dry road surfaces tend to suffer more severe injuries than those who travel in heavy-vehicles, at one-way roads, and on wet road surfaces. Additionally, the driver's seat is clearly the safest seating position, urban areas seem to originate less serious accidents than rural areas, and women tend to be more likely to suffer serious or fatal injuries than men.

Signal averaging helps reliable noninvasive monitoring of left ventricular dimensions based on acoustic quantification (2002)

The acoustic quantification (AQ) technique for on-line endocardial border detection provides continuous left ventricular (LV) area or volume signals, which may allow noninvasive quantification of valuable clinical indices of LV function. However, these signals are distorted by noise, so that accurate interpretation on a beat-to-beat basis is not possible. An automated signal averaging algorithm was developed based on the stochastic sign change as a criterion for temporal beat alignment and rejection of artifacts, in order to improve noise characteristics of the AQ signals. The algorithm was evaluated using area signals obtained from 8 healthy volunteers. The estimates of a set of systolic and diastolic LV function parameters obtained using this algorithm were found to be highly consistent. This approach provides a fast and easy method for noise reduction in AQ signals, which may significantly improve the accuracy of this new noninvasive method of assessment of LV function based on ultrasound technology.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Analysis of N-RAS exon-1 mutations in myelodysplastic syndromes by polymerase chain reaction and direct sequencing (1989)

Mutations in codons 12 or 13 of the first exon of the N-RAS gene have been reported in myelodysplastic syndromes (MDS) in frequencies that vary between 9% and 40% depending on the techniques used in analysis. Gene amplification and direct sequencing provides the only unambiguous method of detecting those mutations that induce amino acid alterations. Using this technique, we analyzed 21 MDS patients for mutations in exon- 1 of N-RAS. Codon 12 mutations substituting aspartic acid (GAT) for glycine (GGT) were found in four cases, and a codon 13 mutation substituting alanine (GCT) for glycine (GGT) was detected in one patient. We conclude that N-RAS exon-1 mutations in one patient. We conclude that N-RAS exon-1 mutations producing amino acid changes occur in about 20% to 25% of MDS cases.
Conductivity Pulses Induced in Insulating Liquids by Ionizing Radiations (1950)

Conductivity pulses due to electron collection have been observed in liquid and solid argon exposed to $\ensuremath{\alpha}$- or $\ensuremath{\gamma}$-radiation. The maximum pulse sizes, ${P}_{M}$, for $\ensuremath{\alpha}$-particles depend only on the field strength, $E$, and not on the electrode spacing, proving that the pulse limiting effect is columnar recombination and not electron trapping by impurities. The maximum pulse sizes obey the equation $(\frac{{P}_{M}}{{P}_{0}})=1\ensuremath{-}\mathrm{exp}(\ensuremath{-}A{E}^{\frac{1}{2}})$, where ${P}_{0}$ is the $\ensuremath{\alpha}$-pulse size in an argon gas counter. The counting efficiency for $\ensuremath{\alpha}$-particles is close to 100 percent, but there is some variation in pulse size due to variation of columnar recombination with angle of emission. No $\ensuremath{\alpha}$- or $\ensuremath{\gamma}$-pulses were observed in liquid nitrogen or heptane, but weak $\ensuremath{\alpha}$-induced pulses were observed in liquid methane.The effects of nitrogen and oxygen in solution in liquid argon in decreasing the pulse sizes are interpreted as being due to electron capture by these molecules.

An event-guided approach to reducing voltage noise in processors (2009)

Supply voltage fluctuations that result from inductive noise are increasingly troublesome in modern microprocessors. A voltage emergency, i.e., a swing beyond tolerable operating margins, jeopardizes the safe and correct operation of the processor. Techniques aimed at reducing power consumption, e.g., by clock gating or by reducing nominal supply voltage, exacerbate this noise problem, requiring ever-wider operating margins. We propose an event-guided, adaptive method for avoiding voltage emergencies, which exploits the fact that most emergencies are correlated with unique microarchitectural events, such as cache misses or the pipeline flushes that follow branch mispredictions. Using checkpoint and rollback to handle unavoidable emergencies, our method adapts dynamically by learning to trigger avoidance mechanisms when emergency-prone events recur. After tightening supply voltage margins to increase clock frequency and accounting for all costs, the net result is a performance improvement of 8% across a suite of fifteen SPEC CPU2000 benchmarks.
Relationship between plasma nitric oxide concentration and insulin resistance in essential hypertension*1 (2004)

Plasma NOx concentrations are highest in those patients with EH who are also insulin resistant/hyperinsulinemic (EH-IR). Furthermore, because plasma NOx concentrations were as high in the EH-IS as in the N-IR populations, it could be speculated that plasma NOx concentrations are also modulated by EH, per se.
Leukapheresis and Granulocyte Transfusion (1979)

Granulocyte transfusion is becoming widely used in the treatment of infections in granulocytopenic patients. Several techniques are available for granulocyte collection. Some involve centrifugation of the whole blood and one removes granulocytes from whole blood by reversible adhesion to nylon fibers. The risks to the donor from leukapheresis do not appear to be greater than from whole blood donation. Granulocytes collected by centrifuge techniques function normally in vitro and have normal intravascular recovery and disappearance following transfusion. Granulocytes collected by filtration leukapheresis function almost normally in vitro but have a reduced intravascular recovery and abnormal kinetics as they leave the circulation. The role of leukocyte typing and compatibility testing for granulocyte transfusion is controversial. When the recipient has circulating antibody against donor leukocytes, transfused leukocytes do not circulate or migrate to sites of infection but are sequestered in the liver and spleen. Clinical studies have not defined whether patients benefit equally well clinically from transfusion of compatible or incompatible granulocytes. Initial reports of clinical trials of granulocyte transfusion were promising. However, similar patients who did not receive granulocytes were not studied. Most subsequent controlled trials showed a clear benefit from granulocyte transfusion while others did not. Differences in antibiotic therapy, chemotherapy, use of laminar flow rooms, and grouping of patients make it difficult to compare these clinical trials. Some, but not all, infected granulocytopenic patients benefit from transfusion. Granulocyte transfusions improve survival of granulocytopenic patients with gram negative sepsis and prolonged bone marrow aplasia. Studies are now attempting to identify other patients who should receive granulocytes, the optimum dose and schedule of transfusions, the optimum time to begin transfusion, and the value, if any, of prophylactic transfusions.
On-Chip Integrated Mid-Infrared GaAs/AlGaAs Mach–Zehnder Interferometer (2012)

We report the design, fabrication, and first functional verification of mid-infrared (MIR; 3-12 μm) Mach-Zehnder interferometers (MZIs). The developed MIR-MZIs are entirely chip-integrated solid-state devices based on GaAs/AlGaAs technology waveguide fabricated via conventional optical lithography and reactive ion etching (RIE). Thus, fabricated MIR-MZIs were combined with a broadly tunable quantum cascade laser (tQCL) providing a wavelength coverage of 5.78-6.35 μm. MIR-MZIs have been designed with a waveguide width of 5 μm to ensure single mode behavior, avoiding optically undefined interference patterns. Several structures with different opening angles of the Y-junction were fabricated and tested for maximizing IR radiation throughput. This study demonstrates the feasibility of the very first chip-integrated mid-infrared Mach-Zehnder structures via interference patterns produced by minute amounts of water deposited at different positions of the MIR-MZI structure.

The molecular basis of glucocorticoid-induced skin atrophy: topical glucocorticoid apparently decreases both collagen synthesis and the corresponding collagen mRNA level in human skin<i>in vivo</i> (1998)

The effects of topical betamethasone-17-valerate on collagen propeptide levels, collagen mRNA level, lysyl oxidase mRNA and matrix metalloproteinase (MMP)-1 and MMP-2 mRNA levels were studied in human skin. Three days' treatment of healthy skin with topical betamethasone caused a 70-80% decrease in type I and III collagen propeptides in suction blister fluid. A similar decrease was found in type I collagen mRNA when assayed by either slot-blot hybridization or a quantitative polymerase chain reaction method, indicating that the decrease in collagen synthesis after topical glucocorticoid treatment is apparently due to a decrease in corresponding mRNA. mRNA of lysyl oxidase, which is an important enzyme catalysing the cross-linking of collagen chains, and collagen-degrading enzyme MMP-1 and MMP-2 mRNAs were not decreased in the same skin samples. This suggests that in vivo, glucocorticoids modulate variably the genes involved in collagen synthesis and degradation. Our study provides a solid molecular basis for glucocorticoid-induced dermal atrophy, which results from the decrease in functional collagen mRNA in the skin.
Real-Time Object Tracking in High-Definition Video Using Frame Segmentation and Background Integral Images (2013)

Object tracking in video sequences is still a challenging issue in real-time video processing. In this paper we propose an integrated detection and tracking method suitable for high-definition videos at real-time frame rates. In this method we implement a frame segmentation procedure using integral images of the background, which permits to discard the analysis of several image parts of each frame and achieve high frame rates. Also we extend the proposed algorithm to detect multiple objects in parallel.

Effect of humidity on hydrogen sensitivity of Pt-gated AlGaN/GaN high electron mobility transistor based sensors (2010)

The effects of relative humidity on sensing characteristics of Pt-gated AlGaN/GaN high electron mobility transistor diode based hydrogen sensors were investigated. The absorbed water and oxygen molecules blocked available Pt surface adsorption sites for H2 absorption and reduced the hydrogen sensing sensitivity compared to low humidity conditions. The hydrogen sensing sensitivity decreased proportional to the relative humidity. However, the presence of humidity improved the sensor recovery characteristics after exposure to the hydrogen ambient.
PKCε Increases Phosphorylation of the Cardiac Myosin Binding Protein C at Serine 302 both in Vitro and in Vivo (2007)

Cardiac myosin binding protein C (cMyBPC) phosphorylation is essential for normal cardiac function. Although PKC was reported to phosphorylate cMyBPC in vitro, the relevant PKC isoforms and functions of PKC-mediated cMyBPC phosphorylation are unknown. We recently reported that a transgenic mouse model with cardiac-specific overexpression of PKCepsilon (PKCepsilon TG) displayed enhanced sarcomeric protein phosphorylation and dilated cardiomyopathy. In the present study, we have investigated cMyBPC phosphorylation in PKCepsilon TG mice. Western blotting and two-dimensional gel electrophoresis demonstrated a significant increase in cMyBPC serine (Ser) phosphorylation in 12-month-old TG mice compared to wild type (WT). In vitro PKCepsilon treatment of myofibrils increased the level of cMyBPC Ser phosphorylation in WT mice to that in TG mice, whereas treatment of TG myofibrils with PKCepsilon showed only a minimal increase in cMyBPC Ser phosphorylation. Three peptide motifs of cMyBPC were identified as the potential PKCepsilon consensus sites including a 100% matched motif at Ser302 and two nearly matched motifs at Ser811 and Ser1203. We treated synthetic peptides corresponding to the sequences of these three motifs with PKCepsilon and determined phosphorylation by mass spectrometry and ELISA assay. PKCepsilon induced phosphorylation at the Ser302 site but not at the Ser811 or Ser1203 sites. A S302A point mutation in the Ser302 peptide abolished the PKCepsilon-dependent phosphorylation. Taken together, our data show that the Ser302 on mouse cMyBPC is a likely PKCepsilon phosphorylation site both in vivo and in vitro and may contribute to the dilated cardiomyopathy associated with increased PKCepsilon activity.

Monomode guiding over 100 Rayleigh lengths (10 cm) of high intensity ultrashort laser pulses ( ${10}^{16}\mathrm{W}/{\mathrm{cm}}^{2}$, 120 fs) has been demonstrated in hollow dielectric capillary tubes (45--70 \ensuremath{\mu}m internal diameter) without inner wall damage. Analytical predictions for coupling conditions and damping length are confirmed experimentally for tubes under vacuum. With 5 to 40 mbar of He gas in the tube, when laser ionization occurs the energy and duration of the transmitted pulse decrease while its spectrum is broadened.
