Dynamic composition of workflows for customized eGovernment service delivery (2002)

Today, many government agencies provide tremendous amount of information and services via the Web, often overwhelming the citizens. Personalization and customization in delivering information and government services remains as a major challenge. In this paper, we present a novel approach for dynamically composing workflows to delivering customized government services to citizens. Such a system is especially important in a government service delivery due to the fact that many autonomous government agencies are involved in providing parts of this service. As a consequence, citizens are often required to first identify these components of the desired service and contact the agencies independently to obtain the needed services. Our proposed system dynamically composes the inter-agency service as well as the related information, tailored to needs of a citizen, by identifying, integrating and coordinating individual components that constitute this service. Our system achieves customized generation of workflows by specifying governmental regulations as a Condition-Action Rule Base to identify the component services. The rule base is a collection of statements about regulatory, functional, geographical and temporal regulations that an inter-agency service needs to adhere to. Our prototype system which also includes visualization of the regulations along with the customization, has been submitted as System Demo paper to this workshop.
A review of wire arc additive manufacturing and advances in wire arc additive manufacturing of aluminium (2018)

Although wire arc additive manufacturing (WAAM) has proven its capability of fulfilling demands of production of medium-to-large-scale components for automotive and allied sectors made up of aluminium, at present, WAAM cannot be applied as a fully fledged manufacturing process because of practical challenges such as under-matched mechanical properties, the presence of large residual stresses and mandatory post-deposition operation for the formed component. This paper is a review of WAAM technology including a brief of WAAM history, status, advantages and constraints of the WAAM field. A focus is provided including the efforts directed towards the reduction of porosity, tensile properties, microstructural investigations and other valuable advancements in the field of WAAM of aluminium. This review was submitted as part of the 2018 Materials Literature Review Prize of the Institute of Materials, Minerals and Mining run by the Editorial Board of MST.

How Much Is a Million (1994)

Many families experience an apparently inherited increased risk of colorectal cancer (CRC) similar to the known syndromes familial adenomatous polyposis (FAP) and hereditary nonpolyposis colorectal cancer (HNPCC). Besides these high-risk syndromes, approximately 10% of all CRC cases come from families with 2 affected 1st-degree relatives, and even 1st-degree relatives to a single case of CRC are at increased risk. Risk subjects from these families frequently show polyps at colonoscopy, which suggests the APC gene as a good candidate susceptibility gene for these attenuated polypotic syndromes. We used the sensitive DHPLC technique to search for possible predisposing germline mutations in the entire APC gene in 91 risk subjects from these high- and low-risk syndromes with unknown predisposing genes. Most exons were also screened for mutations in 96 normal controls and 96 colorectal cancer cases. In our study we probably have identified the most common APC variants in a Swedish population. Among 30 germline variants identified, 1 clearly pathogenic nonsense mutation and 11 putative pathogenic variants (10 missense and one 3' UTR) were found in 20 index patients (22%). Twelve silent as well as 5 intronic variants were considered nonpathogenic. Two of the missense variants found here, E1317Q and D1822V, have previously been related to a difference in risk of colorectal cancer. One variant, 8636C>A, located within the 3' UTR region of the APC gene, was suggested to constitute an additional low risk allele with a similar relative risk as the Jewish I1307K mutation (OR = 1.8; 95% CI, 0.96-3.40). The question of whether all the other variants confer an increased colorectal cancer risk warrants future large association studies.
Islet transplantation under the kidney capsule fully corrects the impaired skeletal muscle glucose transport system of streptozocin diabetic rats. (1996)

Chronic insulin therapy improves but does not restore impaired insulin-mediated muscle glucose uptake in human diabetes or muscle glucose uptake, transport, and transporter translocation in streptozocin diabetic rats. To determine whether this inability is due to inadequate insulin replacement, we studied fasted streptozocin-induced diabetic Lewis rats either untreated or after islet transplantation under the kidney capsule. Plasma glucose was increased in untreated diabetics and normalized by the islet transplantation (110 +/- 5, 452 +/- 9, and 102 +/- 3 mg/dl in controls, untreated diabetics, and transplanted diabetics, respectively). Plasma membrane and intracellular microsomal membrane vesicles were prepared from hindlimb skeletal muscle of basal and maximally insulin-stimulated rats. Islet transplantation normalized plasma membrane carrier-mediated glucose transport Vmax, plasma membrane glucose transporter content, and insulin-induced transporter translocation. There were no differences in transporter intrinsic activity (Vmax/Ro) among the three groups. Microsomal membrane GLUT4 content was reduced by 30% in untreated diabetic rats and normal in transplanted diabetics, whereas the insulin-induced changes in microsomal membrane GLUT4 content were quantitatively similar in the three groups. There were no differences in plasma membrane GLUT1 among the groups and between basal and insulin stimulated states. Microsomal membrane GLUT1 content was increased 60% in untreated diabetics and normalized by the transplantation. In conclusion, an adequate insulin delivery in the peripheral circulation, obtained by islet transplantation, fully restores the muscle glucose transport system to normal in streptozocin diabetic rats.
Conditional Random Fields for Integrating Local Discriminative Classifiers (2008)

Conditional random fields (CRFs) are a statistical framework that has recently gained in popularity in both the automatic speech recognition (ASR) and natural language processing communities because of the different nature of assumptions that are made in predicting sequences of labels compared to the more traditional hidden Markov model (HMM). In the ASR community, CRFs have been employed in a method similar to that of HMMs, using the sufficient statistics of input data to compute the probability of label sequences given acoustic input. In this paper, we explore the application of CRFs to combine local posterior estimates provided by multilayer perceptrons (MLPs) corresponding to the frame-level prediction of phone classes and phonological attribute classes. We compare phonetic recognition using CRFs to an HMM system trained on the same input features and show that the monophone label CRF is able to achieve superior performance to a monophone-based HMM and performance comparable to a 16 Gaussian mixture triphone-based HMM; in both of these cases, the CRF obtains these results with far fewer free parameters. The CRF is also able to better combine these posterior estimators, achieving a substantial increase in performance over an HMM-based triphone system by mixing the two highly correlated sets of phone class and phonetic attribute class posteriors.

Expediting citation screening using PICo-based title-only screening for identifying studies in scoping searches and rapid reviews (2017)

In this sample of datasets, PICo-based title-only screening was able to expedite citation screening for scoping searches and rapid reviews by reducing the number of citations needed to screen but requires a thorough workup of the potential synonyms and alternative terms. Further research which evaluates the feasibility of this technique with heterogeneous datasets in different fields would be useful to inform the generalisability of this technique.
Face detection using multi-modal information (2002)

This paper proposes an object-oriented face detection method using multi-modal fusion of range, color and motion information. Objects are segmented from a complex background using a stereo disparity histogram that represents the range information of the objects. A matching pixel count (MPC) disparity measure is introduced to enhance the matching accuracy. To detect the facial regions among segmented objects, a skin-color transform technique is used with the general skin color distribution (GSCD) modeled by a 2D Gaussian function in a color synthetic normalization (CSN) color space. The motion detection technique of AWUPC (adaptive weighted unmatched pixel count) is defined on the skin-color transformed image where the adaptive threshold value for the motion detection is determined according to the probability of skin color. AWUPC transforms the input color image into a gray-level image that represents the probability of both the skin color and motion information. The experimental results show that the proposed algorithm can detect a moving human object in various environments such as skin color noise and complex background. It can be useful in MPEG-4 SNHC.
A highly conserved region of human erythrocyte ankyrin contains the capacity to bind spectrin. (1993)

Ankyrin has a spectrin-binding region within a central 62-kDa chymotryptic peptide. We examined the spectrin binding ability of a series of smaller ankyrin fragments and recombinant peptides within the 62-kDa domain using a ligand blot assay. The smallest proteolytic fragment that bound was a 12-kDa tryptic peptide starting at amino acid 1068. Peptides containing this region expressed as glutathione S-transferase fusion products also bound spectrin and suggested that residues 1101-1192 were important. In contrast, a fusion protein containing residues 826-898 did not bind spectrin, a surprising finding since this region is known to influence binding affinity. Proteins that bound spectrin on ligand blots also competed for binding in solution, but did so with one-tenth the affinity of the native peptide. Comparing the 62-kDa domains of erythrocyte and brain ankyrins (species that bind spectrin but with 10-fold differences in affinity), the NH2-terminal regions are 0-40% identical, while the regions (1136-1160) common to all binding peptides are 80-90% identical. We hypothesize that the highly conserved region contains an important spectrin-binding site, while the poorly conserved region controls the binding affinity. We speculate that this unique NH2-terminal region is what gives different members of the ankyrin family their signature set of affinities, and accordingly their distinctive cellular localization.
Long term storage of inversion holes at a superlattice/GaAs interface (1986)

We report an investigation of the long term retention characteristic of a hole inversion layer at the interface between an AlAs/GaAs superlattice and GaAs in the dark. The retention time constant at 77 K is measured to be 34 h. From the temperature dependence of the retention time constant, an effective valence-band discontinuity of 0.17 eV is obtained.
Understanding the effects of dielectric medium, substrate, and depth on electric fields and SERS of quasi-3D plasmonic nanostructures (2011)

The local electric field distribution and the effect of surface-enhanced Raman spectroscopy (SERS) were investigated on the quasi-3D (Q3D) plasmonic nanostructures formed by gold nanohole and nanodisc array layers physically separated by a dielectric medium. The local electric fields at the top gold nanoholes and bottom gold nanodiscs as a function of the dielectric medium, substrate, and depth of Q3D plasmonic nanostructures upon the irradiation of a 785 nm laser were calculated using the three-dimensional finite-difference time-domain (3D-FDTD) method. The intensity of the maximum local electric fields was shown to oscillate with the depth and the stronger local electric fields occurring at the top or bottom gold layer strongly depend on the dielectric medium, substrate, and depth of the nanostructure. This phenomenon was determined to be related to the Fabry-Pérot interference effect and the interaction of localized surface plasmons (LSPs). The enhancement factors (EFs) of SERS obtained from the 3D-FDTD simulations were compared to those calculated from the SERS experiments conducted on the Q3D plasmonic nanostructures fabricated on silicon and ITO coated glass substrates with different depths. The same trend was obtained from both methods. The capabilities of tuning not only the intensity but also the location of the maximum local electric fields by varying the depth, dielectric medium, and substrate make Q3D plasmonic nanostructures well suited for highly sensitive and reproducible SERS detection and analysis.
Proliferative T‐Cell Response to HIV Envelope Glycoprotein in Immunized and Infected Primates and Human Beings (1989)

Human immunodeficiency virus (HIV)-specific helper T-cell response was studied in human subjects and nonhuman primates either infected with HIV or immunized with different HIV protein preparations. A strong group-specific T-cell response involving T-cell proliferation and lymphokine secretion was observed in immunized chimpanzees and rhesus monkeys as well as HIV-infected chimpanzees and gibbons. HIV-infected people demonstrated a low or no HIV-specific T-cell response. In contrast, five of 14 HIV antibody-negative sexual partners of HIV-infected men recognized one or more T-cell epitopes in the envelope glycoprotein of HIV.
An Optimized Computer Vision Approach to Precise Well-Bloomed Flower Yielding Prediction using Image Segmentation (2015)

The objective of this paper is to explore the various red colored Rose flowers recognition and yielding through prediction precision using segmentation. The yield concludes an excellent impression with the proper information for image prediction precision for a flower evacuation. The main concern is to detect and yield the blossom roses grown in cultivated land is estimated to amount and the terms; conditions, Luminescence and rose species produce flowers without changing any natural abnormality is to confirm. In dynamic technology, efficient cultivation requires a wide usage in yielding process where segmentation carries basic module in image extraction. The current study use the computerization techniques through thresholding to extract flower and Hue's color code Segmentation through Otsu Algorithm along with Morphological Filters to acquire the fine yielding of highly bloomed rose flowers from an digital snapshot . The procedure of recognition carried out for 230 images. This technique approaches a precise the recognizing, yielding and counting of rose flower at about 83.33% with overall accuracy.
On-chip Clock Testing and Frequency Measurement (2014)

This work presents a method to measure the frequency of an on-chip test clock in relation to a reference clock. Frequency measurement is accomplished by counting pulses of both test and reference clocks, albeit adjusting the reference clock pulse count to estimate the number of pulses that the test clock is expected to see. The proposed method places no constraints on the frequency relationship between the test and reference clocks which allows the reference clock frequency to be any multiple d (1 < d £ 1) of the test clock frequency. Doing so allows a high degree of flexibility and a wide range of scenarios for which this approach could be deployed to measure the frequency of an unknown clock. Applications of this approach range from calibrating the frequency of on chip at speed test clocks for DFT, measurement of ppm of clocks subject to variations in process, temperature, spread spectrum effects among other considerations. The method also guarantees cycle to cycle accuracy in frequency measurement. Multiple on chips clocks can be tested using one instance of this method when the frequency information of all clocks to be tested is made available in specific register files.
Bribie Lakes: A case study in using floating wetland treatment systems to treat urban runoff (2015)

Floating Wetland Treatment Systems (FWTS) have the potential to provide significantly greater stormwater pollution removal rates per unit area compared to constructed wetlands or other treatment systems. As FWTS do not require additional earthworks or land uptake, they can also offer this increased pollution removal performance at significantly lower costs. In addition, the use of floating wetlands in stormwater retention ponds does not affect their hydrological processes or performance. This paper describes an innovative research study currently underway on Bribie Island in Queensland, Australia to evaluate the performance of a floating wetland system used to treat the stormwater runoff from a 10 ha urban catchment. The experimental design of the study is unique on a number of levels. Firstly, the experimental design of the study allows the performance of the new floating wetland system to be monitored and analysed during storm events. The experimental design also incorporates an array of impermeable baffles which directs all of the stormwater runoff through the floating wetlands, eliminating the short-circuiting problems experienced in previous studies. This approach effectively makes the floating wetland an on-line treatment system. This setup enables real-time water sampling to be accurately undertaken to evaluate the pollution removal performance of the system Previous study results suggest that FWTS are effective in removing pollutants when inflow pollutant concentrations are sufficiently high. However, as with all treatment systems, the efficacy is reduced when influent pollutant concentrations are low. Preliminary study results indicate that the catchment runoff pollutant concentrations are significantly lower than those expected for Queensland urban catchments. This has the potential to significantly affect the study results. This paper discusses these and other stormwater monitoring issues.

PPP1R6, a novel member of the family of glycogen‐targetting subunits of protein phosphatase 1 (1997)

A complementary DNA encoding a novel human protein phosphatase 1 (PP1) glycogen-targetting subunit of molecular mass 33 kDa has been sequenced. PPP1R6 is 31% identical to the glycogen-targetting subunit (G(L)) of PP1 from rat liver, 28% identical to the N-terminal region of the glycogen-targetting subunit (G(M)) from human skeletal muscle and 27% identical to glycogen-targetting subunit PPP1R5. Unlike human PPP1R5 and its murine homologue PTG, whose mRNAs are most abundant in skeletal muscle, heart and liver, PPP1R6 is present at similar levels in a wide variety of tissues. The PPP1R6 is associated with glycogen in muscle but is not subject to the same modes of covalent and allosteric regulation as G(M) and G(L).
Identification of novel alternatively spliced <i>BRCA1‐associated RING domain</i> (<i>BARD1</i>) messenger RNAs in human peripheral blood lymphocytes and in sporadic breast cancer tissues (2007)

BARD1 (BRCA1-associated RING domain) is the dominant binding partner of BRCA1 in vivo. The BARD1 gene has been reported to be mutated in a subset of breast and ovarian cancer patients and BARD1 germ-line mutations have been identified in breast cancer patients negative for BRCA1 or BRCA2 gene alterations. In the present study, we show by RT-PCR and direct sequencing analysis the occurrence of seven novel and one previously identified BARD1 splicing variants in human lymphocytes and breast cancers. Two of the eight variants (BARD1delta and BARD1 DeltaRIN) preserve a correct open reading frame and could encode BARD1 internally deleted proteins, while the remaining six variants display premature stop codons. Characterization of the relative expression of BARD1 FL, BARD1delta, and BARD1 DeltaRIN using quantitative PCR analysis indicated that the mean expression levels of BARD1 FL, BARD1delta, and BARD1 DeltaRIN were significantly higher in tumors than in morphologically normal tissues and lymphocytes. However, we were unable to identify either qualitatively or quantitatively tumor-specific expression patterns of the identified BARD1 splicing variants.
An Interactive Deformation System for Granular Material (2005)

Abstract Computer Graphics (CG) animations of natural phenomena are currently widely used for movies and in video games. Granular materials occur widely in nature, and therefore it is necessary that CG animations represent ground surfaces composed of a granular material as well as model deformations when the granular material comes into contact with other physical rigid objects (called solid objects). In this paper, we propose a deformation algorithm for ground surfaces composed of granular material. The deformation algorithm is divided into three steps: (1) detection of the collision between a solid object and the ground surface, (2) displacement of the granular material and (3) erosion of the material at steep slopes. The proposed algorithm can handle solid objects of various shapes, including concave polyhedra by additionally using a layered data structure called the Height Span Map. Furthermore, a texture sliding technique is presented to render the motion of granular materials. In addition, our implementation of the deformation algorithm can be used at interactive frame rates.
