The decorrelation stretch transformation (1996)

Abstract The three-stage decorrelation stretch analysis—transformation to principal component scores; contrast-stretching of the scores to equalise the variances; and reversal of the initial transformation—is shown to produce linear combinations of the original bands which are uncorrelated and have unit variances. As such, the effectiveness of the decorrelation stretch analysis in producing enhanced displays depends fortuitously on the particular contrasts which result. For some examples, setting the first scaled principal component to zero before reversing the initial transformation has little effect on the decorrelation stretch coefficients. In other examples, a small change in the eigenvector defining the first principal component results in only a small change in the decorrelation stretch coefficients and yet produces a distinctly different decorrelation stretch image. A more general formulation of the decorrelation stretch analysis involving simplification and/or exclusion of some of the first-stage vectors is also presented. The general formulation, which involves a diagonal weighting matrix, includes decorrelation stretch; recovery of the original bands; removal of the contribution of noisy principal components; and selective inclusion of principal components as particular cases. Analyses of TIMS (Thermal Infrared Multi-spectral Scanner) data are used to illustrate the approaches, including the sensitivity of the images to small changes in the contrast vectors.
The Measurement of Delinquency in Canada (1967)

This paper reports the final results of a replication study conducted throughout Canada for the purpose of testing the reliability of an index of crime and delinquency recently proposed in the United States by Thorsten Sellin and Marvin Wolfgang, and to examine the possibility of developing such an index for Canada.The results indicate that the index is reliable and that a similar one constructed on the basis of our data would provide the best standardized and common measure of crime and delinquency in Canada.
Kinetics and mechanism of the diazo coupling reaction of arenediazo methyl ethers with β-naphthol. Part 1. The rates of reaction in nonaqueous acid solutions (1988)

Rate data are presented for the diazo coupling reaction of arenediazo methyl ethers with β-naphthol in solutions of dioxane, ethanol, and propan-2-ol acidified with hydrochloric acid at 25°C. Over the range of HCl concentrations studied, pseudo-first-order rate constants were obtained and the reaction was found to be of first order in diazo ether. The relationship between the observed rate constants (kobs.) and hydrochloric acid concentration (cHCl) was found to be non-linear. Correlations of reaction rates with the Hammett acidity function (H0) and with the Hammett substituent constant (σx) conform with a mechanism in which the slow step is unimolecular decomposition of the protonated diazo ether, DEH+, to the coupling entity, the diazonium ion, D+, which instantly reacts with β-naphthol to give the azo dye.
Influence of Hard Segments on the Thermal, Phase-Separated Morphology, Mechanical, and Biological Properties of Polycarbonate Urethanes (2017)

Abstract: In this study, we have fabricated a series of polycarbonate polyurethanes using a two-step bulk reaction by the melting pre-polymer solution-casting method in order to synthesize biomedical polyurethane elastomers with good mechanical behavior and biostability. The polyurethanes were prepared using dibutyltin dilaurate as the catalyst, poly(1,6-hexanediol)carbonate microdiols (PCDL) as the soft segment, and the chain extender 1,4-butanediol (BDO) and aliphatic 1,6-hexamethylene diisocyanate (HDI) as the hard segments. The chemical structures and physical properties of the obtained films were characterized by attenuated total reflectance Fourier transform infrared (ATR-FTIR) spectroscopy, gel permeation chromatography (GPC), differential scanning calorimeter (DSC), and mechanical property tests. The surface properties and degrees of microphase separation were further analyzed by water droplet contact angle measurements (CA) and atomic force microscopy (AFM). The materials exhibited a moderate toxic effect on the tetrazolium (MTT) assay and good hemocompatibility through hemolytic tests, indicating a good biocompatibility of the fabricated membranes. The materials could be considered as potential and beneficial suitable materials for tissue engineering, especially in the fields of artificial blood-contacting implants or other biomedical applications.
Chromatic discrimination by use of computer controlled set of light-emitting diodes (2007)

We propose a novel approach for measurements of two-dimensional distribution of the reflection spectra with high spatial resolution. It is based on a subspace vector model of surface reflections and includes sequential illumination of the object by basis functions preliminary calculated with principal component analysis. A simple optical system consisting of a computer controlled set of light-emitting diodes and a photo-receiver operating in integration regime is used to acquire spatial distribution of reflection spectra in compressed form. The compressed data can be directly used for accurate color classification or recognition. The system's ability to distinguish metameric samples with extremely small hue difference is experimentally demonstrated.

Fever After Aneurysmal Subarachnoid Hemorrhage (2008)

Intraventricular blood is an independent risk factor for the development of fever. In this study, noninfectious fever was rare and not related to extravasated blood or hydrocephalus.
The Impact of the Level of the Intestinal Short Chain Fatty Acids in Inflammatory Bowel Disease Patients Versus Healthy Subjects (2010)

The aim of this study was to determine the changes of short chain fatty acids (SCFAs) in faeces of inflammatory bowel disease (IBD) patients compared to healthy subjects. SCFAs such as pyruvic, lactic, formic, acetic, propionic, isobutyric and butyric acids were analyzed by using high performance liquid chromatography (HPLC). This study showed that the level of acetic, 162.0 micromol/g wet faeces, butyric, 86.9 micromol/g wet faeces, and propionic acids, 65.6 micromol/g wet faeces, decreased remarkably in IBD faecal samples when compared with that of healthy individuals, 209.7, 176.0, and 93.3 micromol/g wet faeces respectively. On the contrary, lactic and pyruvic acids showed higher levels in faecal samples of IBD than in healthy subjects. In the context of butyric acid level, this study also found that the molar ratio of butyric acid was higher than propionic acid in both faecal samples. This might be due to the high intake of starch from rice among Malaysian population. It was concluded that the level of SCFAs differ remarkably between faecal samples in healthy subjects and that in IBD patients providing evidence that SCFAs more likely play an important role in the pathogenesis of IBD.
Platform Independent Overall Security Architecture in Multi-Processor System-on-Chip ICs for Use in Mobile Phones and Handheld Devices (2006)

A platform independent security architecture for use in multi-processor system-on-chip integrated circuits, primarily oriented for mobile phones and handheld devices, is presented. The suggested architecture provides an enhanced security protection scheme for use in smartphones, PDAs, as well as other similar systems. Sensitive data storage facilities, cryptographic engines, and physical protection mechanisms such as debug port access control are presented and described in detail. The proposed secure architecture has been incorporated as a part of an application processor which in turn is embedded in a number of smartphone and handheld products. System operation is discussed and hardware realization and experimental results of the proposed architecture are described.
Trisodium citrate induced protein precipitation in haemodialysis catheters might cause pulmonary embolism (2012)

Our in vitro results demonstrate that protein precipitates inside haemodialysis catheters when trisodium citrate is used above the concentrations of 12%. Precipitated protein may have contributed to the pathophysiology of reported embolisms from haemodialysis catheters filled with hypertonic trisodium citrate. Based on our findings, we suggest that trisodium citrate lock solution up to the concentration of 10% can be used safely.
Osteogenic Protein-1 Up-Regulation of the Collagen X Promoter Activity Is Mediated by a MEF-2-Like Sequence and Requires an Adjacent AP-1 Sequence (1997)

Bone morphogenetic proteins induce chondrogenesis and osteogenesis in vivo. To investigate molecular mechanisms involved in chondrocyte induction, we examined the effect of osteogenic protein (OP)-1/bone morphogenetic protein-7 on the collagen X promoter. In rat calvaria-derived chondrogenic C5.18 cells, OP-1 up-regulates collagen X mRNA levels and its promoter activity in a cell type- specific manner. Deletion analysis localizes the OP-1 response region to 33 bp (−310/−278), which confers OP-1 responsiveness to both the minimal homologous and heterologous Rous sarcoma virus promoter. Transforming growth factor-β2 or activin, which up-regulates the expression of a transforming growth factor-β-inducible p3TP-Lux construct, has little effect on collagen X mRNA and on this 33-bp region. Mutational analysis shows that both an AP-1 like sequence (−294/−285, TGAATCATCA) and an A/T-rich myocyte enhancer factor (MEF)-2 like sequence (−310/−298, TTAAAAATAAAAA) in the 33-bp region are necessary for the OP-1 effect. Gel shift assays show interaction of distinct nuclear proteins from C5.18 cells with the AP-1-like and the MEF-2- like sequences. OP-1 rapidly induces nuclear protein interaction with the MEF-2-like sequence but not with the AP-1 like sequence. MEF-2-like binding activity induced by OP-1 is distinct from the MEF-2 family proteins present in C2C12 myoblasts, in which OP-1 does not induce collagen X mRNA or up-regulate its promoter activity. In conclusion, we identified a specific response region for OP-1 in the mouse collagen X promoter. Mutational and gel shift analyses suggest that OP-1 induces nuclear protein interaction with an A/T-rich MEF-2 like sequence, distinct from the MEF-2 present in myoblasts, and up-regulates collagen X promoter activity, which also requires an AP-1 like sequence.
Digital Repositories at Queensland University of Technology (2005)

University libraries have traditionally played a central role in the institutional core business of creating and sharing knowledge. With the emergence of new technologies, such as digitisation and the Internet, came new possibilities for storing, disseminating and using information resources created at the university – not all involving the library. By working collaboratively with other sections of the university in the development of these new systems, the university library continues to be a relevant and valued participant in this process. For example, university libraries can be instrumental in the development and maintenance of institutional repositories. At Queensland University of Technology (QUT) in Brisbane, the library has played a key role in the development of a number of digital repositories. These include an E-Print archive (QUT ePrints), the Australian Digital Thesis (ADT) collection, a Course Materials Database (CMD) and FlexiPrint, a student-driven print on-demand service of all compatible CMD and Online Teaching materials. All of these projects involve collaboration between the Library and other University staff, eg academic staff, the QUT Office of Research, Teaching and Learning Support Services (TALSS), individual postgraduate students and even other universities. These repositories have enhanced the information resources available within QUT and have enabled the sharing of QUT-created information resources globally. The collaborative nature of the projects has also strengthened the partnership between the Library, other sections within the Division of Technology, Information and Learning Support and the QUT academic community.
Printable die attach adhesives for substrate-on-chip packaging (2004)

The dominant trend in packaging DDR DRAM for the future is the face down substrate-on-chip configuration. For this type of package it is critical that the die attach method employed provide precise control of bond line thickness and die tilt, minimal fillet, and prevent contamination of the wire bond pads located on the edge of the center wire bond channel. To date, a film adhesive has been the die attach method of choice because it is well suited to meet those requirements. Unfortunately, films are quite expensive compared to die attach pastes in terms of material, process, and tooling costs. This is especially true when changes such as die shrinks and board redesigns mandate a taping tool change. To address this serious issue, a novel series of printable B-stage adhesives has been developed that deliver the performance of a film (with respect to bond line and flow control), with the low cost of a paste (in terms of tooling and materials).In this paper, we will present data on a commercial series and a developmental series of printable adhesives, which were developed specifically for substrate-on-chip packages. These proprietary adhesives are formulated to be stencil printed on a substrate and then B-staged. The printed substrates then replace the standard pre-taped substrates that represent the mainstream in DRAM packaging. Data show that these printable adhesives deliver the performance of films, i.e. low flow and bond-line control on die attach, more than a six month storage life at room temperature, and do not require substrate pre-drying. ChipMOS Technologies has pioneered the assembly process using these adhesives and are seeing high UPH and equivalent reliability performance to film adhesives. Key in-package reliability data from those evaluations will be presented.
Unrolled Memory Inner-Products: An Abstract GPU Operator for Efficient Vision-Related Computations (2017)

Recently, convolutional neural networks (CNNs) have achieved great success in fields such as computer vision, natural language processing, and artificial intelligence. Many of these applications utilize parallel processing in GPUs to achieve higher performance. However, it remains a daunting task to optimize for GPUs, and most researchers have to rely on vendor-provided libraries for such purposes. In this paper, we discuss an operator that can be used to succinctly express computational kernels in CNNs and various scientific and vision applications. This operator, called Unrolled-Memory-Inner-Product (UMI), is a computationally-efficient operator with smaller code token requirement. Since a naive UMI implementation would increase memory requirement through input data unrolling, we propose a method to achieve optimal memory fetch performance in modern GPUs. We demonstrate this operator by converting several popular applications into the UMI representation, and achieve 1.3x-26.4x speedup against frameworks such as OpenCV and Caffe.
A Novel Arc Fault Detector for Early Detection of Electrical Fires (2016)

Arc faults can produce very high temperatures and can easily ignite combustible materials; thus, they represent one of the most important causes of electrical fires. The application of arc fault detection, as an emerging early fire detection technology, is required by the National Electrical Code to reduce the occurrence of electrical fires. However, the concealment, randomness and diversity of arc faults make them difficult to detect. To improve the accuracy of arc fault detection, a novel arc fault detector (AFD) is developed in this study. First, an experimental arc fault platform is built to study electrical fires. A high-frequency transducer and a current transducer are used to measure typical load signals of arc faults and normal states. After the common features of these signals are studied, high-frequency energy and current variations are extracted as an input eigenvector for use by an arc fault detection algorithm. Then, the detection algorithm based on a weighted least squares support vector machine is designed and successfully applied in a microprocessor. Finally, an AFD is developed. The test results show that the AFD can detect arc faults in a timely manner and interrupt the circuit power supply before electrical fires can occur. The AFD is not influenced by cross talk or transient processes, and the detection accuracy is very high. Hence, the AFD can be installed in low-voltage circuits to monitor circuit states in real-time to facilitate the early detection of electrical fires.
Influence of Kiln Atmospheres in Firing Structural Clay Products: I, Maturation and Technological Properties* (1971)

The effects of kiln atmosphere on a low‐maturing shale and a moderately refractory fireclay fired in a pilot shuttle kiln using natural gas were studied. Bricks were fired in both oxidizing and reducing atmospheres, with emphasis on variable water vapor concentrations. The chemical and physical benefits of proper atmosphere selection and control are shown. Kiln atmosphere influenced absorption, shrinkage, strength, scumming, lime popping, frost resistance, and temperature uniformity. Results indicate that firing techniques with rapid schedules and significant reductions in maturing temperatures are feasible without sacrificing product quality.
85 Gbit/s WDM transmission of 165.3 Gbit/s RZ data signals over 7931 km using accurate gain-equalisationand pre-compensation of group-velocity-dispersion (1997)

The authors demonstrate wavelength-division-multiplexing (WDM) transmission of 16 5.3 Gbit/s signals over 7931 km using a non-soliton return-to-zero (RZ) modulation format. In this experiment, a gain equalisation scheme is applied using two types of optical filters to accurately equalise the asymmetric gain profile of an EDFA chain, and a pre-compensation technique of group-velocity-dispersion (GVD) to reduce SPM-GVD penalties. These techniques made the WDM transmission of 16 channels possible without a serious channel imbalance in transmission performance.
Conceptual Graphs Based Information Retrieval in HealthAgents (2007)

This paper focuses on the problem of representing, in a meaningful way, the knowledge involved in the HealthAgents project. Our work is motivated by the complexity of representing electronic healthcare records in a consistent manner. We present HADOM (HealthAgents domain ontology) which conceptualises the required HealthAgents information and propose describing the sources knowledge by the means of conceptual graphs (CGs). This allows to build upon the existing ontology permitting for modularity and flexibility. The novelty of our approach lies in the ease with which CGs can be placed above other formalisms and their potential for optimised querying and retrieval.
Dendrimer Enhanced Ultrafiltration. 1. Recovery of Cu(II) from Aqueous Solutions Using PAMAM Dendrimers with Ethylene Diamine Core and Terminal NH<sub>2</sub> Groups (2005)

This article discusses the feasibility of using dendrimer enhanced ultrafiltration (DEUF)to recover Cu(II) from aqueous solutions. Building upon the results of fundamental investigations of Cu(II) binding to PAMAM dendrimers with ethylenediamine (EDA) core and terminal NH2 groups, we combine (i) dead-end ultrafiltration (UF) experiments with (ii) atomic force microscopy (AFM) characterization of membrane fouling to assess the feasibility of using DEUF to recover Cu(II) from aqueous solutions. On a mass basis, the Cu(II) binding capacities of the EDA core PAMAM dendrimers are much larger and more sensitive to solution pH than those of linear polymers with amine groups. The dendrimer-Cu(II) complexes can be efficiently separated from aqueous solutions by ultrafiltration. The metal ion laden dendrimers can be regenerated by decreasing the solution pH to 4.0; thus enabling the recovery of the bound Cu(II) ions and recycling of the dendrimers. The UF measurements and AFM characterization studies show that EDA core PAMAM dendrimers with terminal NH2 groups have very lowtendency to foul the commercially available regenerated cellulose (RC) membranes evaluated in this study. The overall results of these experiments suggest that DEUF is a promising process for recovering metal ions such as Cu(II) from aqueous solutions.
Optical Sensor System for Hemoglobin Measurement (2013)

For complete blood count Hemoglobin (Hb) is an essential parameter. This paper presents non invasive optical technique for Hb measurement. At different wavelengths absorption coefficient of blood differs this fact is used to measure the optical characteristics of blood. In this newly developed system, principle of pulse oximetry is used. Oxygenated and deoxygenated hemoglobin absorbs different amount of light at two wavelength 660nm and 940nm. Red and IR LED are used for these particular wavelengths. Transmitted light through an area of skin on finger was detected by a transimpedance amplifier photodiode. Ratio of pulsating to non pulsating component of both red and IR signal after normalization is calculated for determination of Hb. Signal acquisition by this method is totally noninvasive. The sensors assembled in this investigation are fully integrated into wearable finger clips.
Role of hypoxia in the hallmarks of human cancer (2009)

Hypoxia has been recognized as one of the fundamentally important features of solid tumors and plays a critical role in various cellular and physiologic events, including cell proliferation, survival, angiogenesis, immunosurveillance, metabolism, as well as tumor invasion and metastasis. These responses to hypoxia are at least partially orchestrated by activation of the hypoxia-inducible factors (HIFs). HIF-1 is a key regulator of the response of mammalian cells to oxygen deprivation and plays critical roles in the adaptation of tumor cells to a hypoxic microenvironment. Hypoxia and overexpression of HIF-1 have been associated with radiation therapy and chemotherapy resistance, an increased risk of invasion and metastasis, and a poor clinical prognosis of solid tumors. The discovery of HIF-1 signaling has led to a rapidly increasing understanding of the complex mechanisms involved in tumor hypoxia and has helped greatly in screening novel anticancer agents. In this review, we will first introduce the cellular responses to hypoxia and HIF-1 signaling pathway in hypoxia, and then summarize the multifaceted role of hypoxia in the hallmarks of human cancers.
