Classification for hyperspectral imaging (2014)

Hyperspectral Imaging is a method of collecting and processing the information across pre-defined electromagnetic spectrum. These measurements make it possible to derive a continuous spectrum for each pixel of the image. After necessary adjustments these image spectra can be compared with database of reflectance spectra in order to recognise tested materials. This project is conducted in cooperation between Fraunhofer Centre for Applied Photonics and Heriot-Watt Industrial Doctorate Centre in Photonics and Optics Technologies in partnership with University of Strathclyde. Fraunhofer Institute is known of world-class photonics solutions and this project aims in enhancement of one of their Hyperspectral Imaging systems with signal processing techniques. Set of classification procedures would be applied for the output of imaging spectrometer with the intention of spatial and spectral classification of objects captured by the spectrometer. Spatial classification is based on Support Vector Machine (SVM) classifier. Use of texture features of the objects is considered as a base for labelling of detected items. Spectral classification is based on Partial Least Squares (PLS) method. With database of calibration reflectance spectra, method this can be used for prediction of “end members” concentration and therefore identification of the objects captured on the hyperspectral image. “
Abstract P078: Re-evaluation of Prognostic Values of Clockwise and Counterclockwise Rotation for Total and Cardiovascular Mortality in a Different Cohort (20 Year Follow-up of NIPPON DATA90) (2016)

Background: We previously reported that electrocardiographic (ECG) clockwise rotation (CWR) was positively and counter-clockwise rotation (CCWR) was inversely associated with cardiovascular disease (CVD) mortality in Japanese using 24 Year Follow-up of NIPPON DATA80. Re-evaluation of the prognostic values of CWR and CCWR in a different cohort is needed. Methods: We studied prognostic values of CWR and CCWR on total and CVD mortality using the NIPPON DATA90 database with a 20-year follow-up. At the baseline in 1990, data were collected on study participants, ages 30 years and over, from randomly selected areas in Japan. We followed 8,262 participants without major ECG abnormalities, or history of stroke or myocardial infarction (41.8% men, mean age 53.0 y) for 20 years. Analysis was made in men and women combined. Results: Among participants, 49.9% were in the normal rotation group, 7.2% in CWR group, and 42.9% in CCWR group. During the 20 year follow-up, there were 1,997 total, and 605 CVD mortality. The multivariate-adjusted hazard ratio (HR) using the Cox model including age, sex, BMI, alcohol and smoking status, hypertension, diabetes and other ECG variables revealed that CWR was significantly positively associated with total mortality (HR=1.19, 95% confidence intervals [CI]: 1.02-1.39, P=0.032), but not with CVD mortality (HR=0.99 [0.68-1.33], P=0.95). CCWR was significantly inversely associated with CVD (HR=0.81 [0.68-0.96], P=0.016), and total mortality (HR=0.91 [0.83-0.997], P=0.043). Conclusions: We have reconfirmed a significant positive association of CWR in total mortality, and a significant inverse association of CCWR with CVD and total mortality in men and women combined, independent of confounding factors including other ECG changes.
Significant Enhancement of Triboelectric Charge Density by Fluorinated Surface Modification in Nanoscale for Converting Mechanical Energy (2015)

Excellent triboelectric and mechanical properties are achieved on the same material for the first time by developing an effective, general, straightforward, and area‐scalable approach to surface modification of a polyethylene terephthalate (PET) film via inductive‐coupled plasma etching. The modification enables gigantic enhancement of triboelectric charge density on the PET surface. Based on the modified PET as a contact material, a triboelectric nanogenerator (TENG) exhibits significantly promoted electric output compared to the one without the modification. The obtained electric output is even superior to a TENG made of conventional polytetrafluoroethylene that is known for its strongest ability of being charged by triboelectrification among all engineering plastics. Detailed characterizations reveal that the enhancement of triboelectric charge density on the PET is attributed to both chemical modification of fluorination and physical modification of roughened morphology in nanoscale. Therefore, this work proposes a new route to obtaining high‐performance TENGs by manipulating and modifying surface properties of materials.

Compositional Dependence of Optical Properties of Nd&lt;sup&gt;3+&lt;/sup&gt; in Gallate Glasses (1996)

The Judd-Ofelt parameters, spontaneous emission probabilities from the 4F3/2 level, quantum efficiency, and stimulated emission cross section of the 4F3/2→4I11/2 transition for Nd3+ are studied for potassium tantalum and lead bismuth gallate glasses. The results reveal that the tantalum gallate glasses have high Ω2 values being comparable to that of Ge-Ga-S glass. The lead bismuth gallate glasses have high stimulated emission cross sections over 4pm2 because of their high refractive indexes. The variations of the JO parameters with composition are discussed in terms of glass structure.

Gap solitons in a two-channel microresonator structure (2002)

We show that, when two channel waveguides are coupled by a sequence of periodically spaced microresonators, the group-velocity dispersion is low in the vicinity of the gap associated with the resonant frequency of the resonators. This low dispersion permits the excitation of a gap soliton with much lower energy than in a gap of similar width caused by Bragg reflection.

A decision-support system for quote generation (2002)

In this paper, we describe a prototype agent-based decision-support system for helping suppliers respond to requests for quote in a business-to-business supply chain. The system provides suggested ways of fulfilling requests and shows alternatives that illustrate tradeoffs in quality, cost and timelines, which allows the decision maker to consider alternatives that reduce cost and improve customer value. The system is implemented in Java and we use examples from paper manufacturing to illustrate the features of our system. In on going work, we are enhancing the prototype to include probabilistic reasoning techniques so that it can create conditional plans that maximize expected utility, subject to the risk preferences of the decision maker. We are also exploring the use of data mining techniques to infer customer preferences and to estimate the probability of winning an order, with a given quote.
BiomarCaRE: rationale and design of the European BiomarCaRE project including 300,000 participants from 13 European countries (2014)

Biomarkers are considered as tools to enhance cardiovascular risk estimation. However, the value of biomarkers on risk estimation beyond European risk scores, their comparative impact among different European regions and their role towards personalised medicine remains uncertain. Biomarker for Cardiovascular Risk Assessment in Europe (BiomarCaRE) is an European collaborative research project with the primary objective to assess the value of established and emerging biomarkers for cardiovascular risk prediction. BiomarCaRE integrates clinical and epidemiological biomarker research and commercial enterprises throughout Europe to combine innovation in biomarker discovery for cardiovascular disease prediction with consecutive validation of biomarker effectiveness in large, well-defined primary and secondary prevention cohorts including over 300,000 participants from 13 European countries. Results from this study will contribute to improved cardiovascular risk prediction across different European populations. The present publication describes the rationale and design of the BiomarCaRE project.
Pressure effects on dipalmitoylphosphatidylcholine bilayers measured by deuterium nuclear magnetic resonance (1991)

The effects of pressure, up to 5 kbar, on multilamellar vesicles of 1,2-dipalmitoyl-sn-phosphatidylcholine perdeuterated in the acyl chains (DPPC-d62) were examined by using high-pressure NMR techniques. A deuterium probe was built, and the quadrupole splitting was measured against pressure at various temperatures. The experiments were performed on pure lipid bilayers in the liquid-crystalline state and on bilayers in the liquid-crystalline state containing the local anesthetic tetracaine. The results show that the order parameter of all segments of the acyl chains increases with pressure in the liquid-crystalline state. The more highly ordered regions of the chains are affected slightly more than the regions near the methyl ends. The addition of tetracaine increases the disorder of the chains, and pressure reverses the effect of anesthetic on the lipid as seen by the reversal of the changes in line shape and the measured order parameter.
Structural Changes during the Photorepair and Binding Processes of <i>Xenopus</i> (6–4) Photolyase with (6–4) Photoproducts in Single- and Double-Stranded DNA (2021)

Photolyases (PHRs) repair ultraviolet (UV)-induced DNA photoproducts into normal bases. In this study, we measured the conformational changes upon photoactivation and photorepair processes of a PHR and its specific substrates, (6-4)PHR and a pyrimidine(6-4)pyrimidone photoproduct ((6-4)PP), by light-induced difference Fourier transform infrared (FT-IR) spectroscopy. The single-stranded DNA with (6-4)PP (ss(6-4)PP) was used as a substrate and the resultant FT-IR spectra were compared with the previous results on double-stranded DNA with (6-4)PP (ds(6-4)PP). In the excess amount of substrate to the enzyme, different ss(6-4)PP photorepair FT-IR signals were obtained in an illumination time-dependent manner. As reported for ds(6-4)PP, the early stages of the photoreaction involve the changes in the ss(6-4)PP only, while the late stages of the reaction involve the ss(6-4)PP repair-associated changes and dissociation from (6-4)PHR. From these spectra, difference spectra originating from the binding/dissociation spectrum were extracted. The signals of the C═O stretches of (6-4)PP and repaired thymines in the single- and double-stranded DNA were tentatively assigned. The C═O stretches of (6-4)PP were observed at frequencies that reflect single- and double-stranded DNA environments in aqueous solution, reflecting the different hydrogen-bonding environments. The conformational changes of PHR upon binding of ss(6-4)PP and ds(6-4)PP were similar, suggesting that the conformational change is limited to the (6-4)PP binding pocket region. We interpreted that ds(6-4)PP may be bound together without any special mechanism for flipping out.
Silica nanoparticle-induced toxicity in mouse lung and liver imaged by electron microscopy (2015)

Nanomaterials have been proposed as novel substrates for medical and commercial applications. However, such materials also may have novel toxicities, thus posing environmental and health concerns. We previously reported hepatic injury in mice following the intravenous administration of unmodified silica particles with diameters of 70 nm (SP70); this toxicity was not observed following administration by the same route of micro-size particles with diameters of 300 nm (SP300) or 1,000 nm (SP1000). In the present study, we used electron microscopy to investigate the dynamics of silica nanoparticles administered in mice. SP70 was observed in hepatocytes and in lung epithelial cells. Inclusion within hepatocytes was associated with accumulation of SP70 in the liver sinusoidal endothelial cells and passage through the space of Disse. In contrast, SP300 and SP1000 were not observed within the hepatocytes. To our knowledge, our report represents the first demonstration that silica nanoparticles accumulate in hepatocytes, liver sinusoidal endothelial cells, Kupffer cells, and lung tissue; accumulation of SP70 in liver sinusoidal endothelial cells correlated with the induction of liver injury.

Characterization of chilean hazelnut (<i>Gevuina avellana</i> mol) seed oil (1998)

Abstract The fatty acid composition, tocopherol and tocotrienol content, and oxidative stability of petroleum benzene‐extracted Gevuina avellana Mol (Proteaceae) seed oil were determined. Positional isomers of monounsaturated fatty acids were elucidated by gas chromatography‐electron impact mass spectrometry after 2‐alkenyl‐4,4‐dimethyloxazoline derivatization. This stable oil (Rancimat induction period at 110°C: 20 h) is composed of more than 85% monounsaturated fatty acids and about equal amounts (6%) of saturated and polyunsaturated (principally linoleic) fatty acids. Unusual positional isomers of monounsaturated fatty acids, i.e., C 16:1 Δ 11 , C 18:1 Δ 12 , C 20:1 Δ 11 , C 20:1 Δ 15 , C 22:1 Δ 17 , and presumably C 22:1 Δ 19 were identified. The C 18:1 Δ 12 and C 22:1 Δ 19 fatty acids are described for the first time in G. avellana seed oil. While only minute quantities of α‐, γ‐tocopherols and β‐, γ‐ and δ‐tocotrienols were found, the oil contained a substantial amount of α‐tocotrienol (130 mg/kg). The potential nutritional value of G. avellana seed oil is discussed on the basis of its composition.

Development of CMG Wheels for Stress Relief in Si Wafer Thinning Process (2011)

In recent semiconductor industry, production of ever flatter, thinner and larger Si wafer are required to fulfill the demands in high integration and cost reduction. A severe problem encountered in wafer thinning process is the warp and distortion of wafer induced by the residual stress and subsurface damage. Chemo-mechanical grinding (CMG) process is emerging process which combines the advantages of fixed abrasive machining and chemical mechanical polishing (CMP), offers a potential alternative for stress relief. This paper studies the influence of the wheel manufacturing process on the wheel physical properties. Three-factor two-level full factorial designs of experiment are employed to reveal the main effects and interacted effects of mixing method and filtration of raw materials on the bending strength and elastic modulus of CMG wheel. The difference in wheel properties is discussed by association with CMG performance including wheel wear, grinding force and surface roughness.

PVC experiments-first rate lab apparatus from plastic plumbing, adhesive, and imagination (2002)

The present paper is intended to assist faculty who wish to develop undergraduate instructional laboratory apparatus, but who have only limited financial resources available. The paper attempts to make interested faculty aware of how simple, low cost, readily available PVC materials and products can be utilized to create first rate laboratory experiments. Although much of the information provided might be familiar to some home owners who undertake their own renovations and repairs, it is felt that the ideas expressed here may prove to be a revelation to many faculty who had previously considered the purchase of packaged experiments as their only option. Tips are given on types and sources of PVC, fabrication techniques and some example experiments are discussed.
Temperature-Dependent RF Characteristics of Al₂O₃-Passivated WSe₂ MOSFETs (2020)

Of all two-dimensional semiconductor crystals, WSe <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> is particularly interesting due to its sizable bandgap, high carrier mobility, and compatibility with large-scale synthesis. By passivating WSe2 MOSFETs with atomic-layer-deposited Al <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> O <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</sub> , they are stable in room environment for more than five months. The passivation also increases their current capacity by two orders of magnitude. Their cutoff frequencies peak around room temperature, with the forward current cutoff frequency f <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">T</sub> ~ 0.6 GHz and the maximum frequency of oscillation f <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">MAX</sub> ~ 2 GHz. These results show WSe <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> is a promising material for gigahertz thin-film transistors. However, if the surface passivation is not optimized, fixed charge in the passivation layer may lead to temporal and temperature instabilities.
2B14 Efficient Modeling of the Damping Performance of Piezoelectric Switching Techniques using Harmonic Balance Method (2010)

Piezoelectric switching networks for vibration damping offer advantages compared to classical inductance-resistance circuits. However, the strong nonlinearity of these networks must be accounted for in the modeling. Especially for the calculation of frequency response functions a linear replacement system can drastically reduce the computational effort. In this paper the synchronized switch damping on inductor (SSDI)-circuit is substituted by an equivalent linear circuit, which can be used to obtain the frequency response. Measurements on a clamped beam with attached piezoceramics are conducted to validate the results.
An immunohistological study of benign and skin tumours: epithelial aspects (1984)

Biopsies of normal skin and benign and malignant skin tumours were studied immunohistologically with nine monoclonal antibodies. The study showed that monoclonal antibodies can clearly delineate antigens expressed in different regions of normal skin and that, in general, tumours retain the antigenic pattern characteristic of the region from which they have arisen. These findings indicate the potential value of analysing these patterns of antigenic expression with a panel of monoclonal antibodies both for understanding the pathogenesis of skin tumours (e.g. basal cell carcinomas) and in their differential diagnosis (e.g. squamous cell carcinoma versus keratoacanthoma).
<i>Bacillus anthracis</i>Aerosolization Associated with a Contaminated Mail Sorting Machine (2002)

On October 12, 2001, two envelopes containing Bacillus anthracis spores passed through a sorting machine in a postal facility in Washington, D.C. When anthrax infection was identified in postal workers 9 days later, the facility was closed. To determine if exposure to airborne B. anthracis spores continued to occur, we performed air sampling around the contaminated sorter. One CFU of B. anthracis was isolated from 990 L of air sampled before the machine was activated. Six CFUs were isolated during machine activation and processing of clean dummy mail. These data indicate that an employee working near this machine might inhale approximately 30 B. anthracis-containing particles during an 8-h work shift. What risk this may have represented to postal workers is not known, but this estimate is approximately 20-fold less than a previous estimate of sub-5 micro m B. anthracis-containing particles routinely inhaled by asymptomatic, unvaccinated workers in a goat-hair mill.
