Search results side note: Creating information search context in creative design process (2016)

Information involves in design process, and in fact designing is an activity of converting data, information and knowledge into a map and guidance of creating an artifact. Unfortunately, the existing instruments that supporting designers' information search do not fit to them in term of their naturally way of doing so. This research is aimed at developing an information search application purposely for designers especially in the creative design process. And this paper will focus on the development and implementation a so called Search Result Side Note application.
A Fractal Geometric Model Of Light Pulse Propagation In A Multilayer Ocean (1986)

A method for modelling light pulse propagation through a multilayer ocean is presented which employs metric analysis using fractals. Fractal analysis is a novel method which, in this application, has the follcmin,g features: 1. nonlinear surface and volume scattering, absorption, reflection, and refraction can be described from empirical data, 2. the optical path length of multiple-collision scattering paths can be computed using the fractal dimension, yielding improved processing speed, and 3. radiative transfer between multiple layers can be described in terms of a convolutional method which is not computationally burdensome. Vertical and temporal scalar irradiance distributions are computed and compared with previously published results. The effect of multiple scattering on beamspread and temporal pulse distortion is discussed in terms of the fractal dimension and irradiance field profiles. Although the model can be quite complex, its computational load is shown to be low.
Recovery of Fission Product Palladium from Acidic High Level Waste Solutions (1996)

Abstract The recovery of palladium from a synthetic pressurized heavy water reactor high level waste (PHWR-HLW) solution has been carried out, and the best reagents to use for the actual HLW solutions are discussed. The extraction of palladium from nitric acid solutions has been carried out using Cyanex-471X (triisobutylphosphine sulfide, TIPS) as the extractant. The metal ion could be quantitatively extracted from solutions with nitric acid concentrations between 2.0 and 6.0 M. The species extracted into the organic phase was found to be Pd(NO3)2 TIPS. Nitric acid in the range of 2. 0 to 5. 0 M had no effect on TIPS for at least 71 hours. A systematic study of gamma irradiation on loading and stripping of palladium from loaded organic phases using several potential extractants, TIPS, alpha benzoin oxime, dioctylsulfide, and dioctylsulfoxide has been made. A flow sheet for the recovery of palladium from actual HLW solutions using TIPS is proposed.
Review The suppressors of cytokine signalling (SOCS) (2001)

Members of the SOCS (suppressor of cytokine signalling) family of proteins play key roles in the nega- tive regulation of cytokine signal transduction. A series of elegant biochemical and molecular biological studies has revealed that these proteins act in a negative feedback loop, inhibiting the cytokine-activated Janus kinase/sig- nal transducers and activators of transcription (JAK/ STAT) signalling pathway to modulate cellular responses. Although structurally related, the precise mechanisms of SOCS-1, SOCS-3 and cytokine-inducible SH2-contain- ing protein (CIS) action vary. Direct interaction of SOCS SH2 domains with the JAK kinases or cytokine receptors allows their recruitment to the signalling complex, where they inhibit JAK catalytic activity or block access of the STATs to receptor binding sites. The defining feature of the family, the C-terminal SOCS box domain, appears dispensable for these actions but is likely to play a key role in negative regulation of signalling by targeting mol- ecules associated with the SOCS proteins for degrada- tion. The relevance of SOCS-mediated regulation of cy- tokine responses has been brought into sharp focus by the dramatic phenotypes of mice lacking these regulators. In- dispensable roles for members of this family have been identified in the regulation of interferon g, growth hor- mone and erythropoietin, and the absence of SOCS-1 or SOCS-3 is lethal in mice.

GENERAL PRACTICE NURSE DIABETES CARE: WHAT DO PATIENTS EXPERIENCE? (2016)

In Australia Type 2 Diabetes (T2D) prevalence is rising rapidly and is expected to become the leading cause of disease burden in 2030 (AIHW, 2010). The General Practice Nurse (GPN) role is increasingly recognised as playing an important part in T2D management through clinical assessment and education supporting patient self-management as part of the general practice multidisciplinary care team (The Royal Australian College of General Practitioners and Diabetes Australia, 2014).
The Effect of Dopants on the Magnetoresistance of WTe2 (2015)

Elucidating the nature of the large, non-saturating magnetoresistance in WTe2 is a significant step in functionalizing this phenomenon for applications. Here, Mo, Re, and Ta doped WTe2 are compared to determine whether isovalent and aliovalent substitutions have different effects on the large magnetoresistance. By 1% substitution, isoelectronic doping reduces the magnetoresistance by a factor of 1.2 with an apparent linear trend, whereas aliovalent doping reduces the effect by over an order of magnitude while following a higher-order decay. The apparent increased sensitivity of the magnetoresistive effect to aliovalent doping over simple isoelectronic disorder supports the conclusion that the large magnetoresistance in WTe2 arises from interactions between balanced hole and electron populations.
PPE Antigen Rv2430c of Mycobacterium tuberculosis Induces a Strong B-Cell Response (2003)

The variation in sequence and length in the C-terminal region among members of the unique PE (Pro-Glu) and PPE (Pro-Pro-Glu) protein families of Mycobacterium tuberculosis is a likely source of antigenic variation, giving rise to the speculation that these protein families could be immunologically important. Based on in silico analysis, we selected a hypothetical open reading frame (ORF) encoding a protein belonging to the PPE family and having epitopes with predictably higher antigenic indexes. Reverse transcriptase PCR using total RNA extracted from in vitro-cultured M. tuberculosis H37Rv generated an mRNA product corresponding to this gene, indicating the expression of this ORF (Rv2430c) at the mRNA level. Recombinant protein expressed in Escherichia coli was used to screen the sera of M. tuberculosis-infected patients, as well as those of clinically healthy controls (n = 10), by enzyme-linked immunosorbent assay. The panel of patient sera comprised sera from fresh infection cases (category 1; n = 32), patients with relapsed tuberculosis (category 2; n = 30), and extrapulmonary cases (category 3; n = 30). Category 2 and 3 sera had strong antibody responses to the PPE antigen, equal to or higher than those to other well-known antigens, such as Hsp10 or purified protein derivative (PPD). However, a higher percentage of patients belonging to category 1, as opposed to clinically healthy controls, showed stronger antibody response against the PPE protein when probed with anti-immunoglobulin M (IgM) (71 versus 37.5%) or anti-IgG (62.5 versus 28.12%). Our results reveal that this PPE ORF induces a strong B-cell response compared to that generated by M. tuberculosis Hsp10 or PPD, pointing to the immunodominant nature of the protein.
Guided nuclear exploration increases CTCF target search efficiency (2018)

Mammalian genomes are enormous. For a DNA-binding protein, this means that the number of non-specific, off-target sites vastly exceeds the number of specific, cognate sites. How mammalian DNA-binding proteins overcome this challenge to efficiently locate their target sites is not known. Here through live-cell single-molecule tracking, we show that CCCTC-binding factor, CTCF, is repeatedly trapped in small zones in the nucleus in a manner that is largely dependent on its RNA-binding region (RBR). Integrating theory, we devise a new model, Anisotropic Diffusion through transient Trapping in Zones (ADTZ), to explain this. Functionally, transient RBR-mediated trapping increases the efficiency of CTCF target search by ∼2.5 fold. Since the RBR-domain also mediates CTCF clustering, our results suggest a “guided” mechanism where CTCF clusters concentrate diffusing CTCF proteins near cognate binding sites, thus increasing the local ON-rate. We suggest that local “guiding” may represent a general target search mechanism in mammalian cells.
Spectral selection of excitonic transitions in a dense array of CdSe/ZnSe quantum dots (2016)

Abstractauthoren We demonstrate that the selection of a limited number of single excitonic lines from a dense array of epitaxial quantum dots (QDs) can be realized spectrally via resonant energy transfer from a huge number of small QDs toward a limited set of large nano-islands through their excited levels. Optical and transmission electron microscopy studies support this mechanism. Theoretical modeling describes the architecture of quantum levels in the array of CdSe/ZnSe QDs, which enables such a spectral selection. Schematic of resonant energy transfer between QDs shown together with a plan-view TEM image of a QD array.
Manifestation of ray chaos in optical cavities (2011)

The correspondence between ray and wave descriptions for twodimensional chaotic open billiards describing optical cavities is reviewed. Focusing on the stadium-shaped cavity, which is well-known for its fully chaotic ray dynamics, we show how ray chaos is manifested in emission patterns, or eigenfunctions of resonances (decaying eigenmodes). The flux phase-space distribution is introduced, which not only enables one to understand the relation between ray dynamics and emission directionality, but also provides a suitable stage to study the ray-wave correspondence. We observe intrinsic localization phenomenon in each resonance, which causes discrepancies with the ray description. Nonetheless, we demonstrate that the average of many low-loss resonances reproduces the ray description very well, where one can clearly observe that signature of ray chaos (i.e., long-term effects of stretching and folding) is embedded in resonance eigenfunctions.
Preparation, Characterization and Wound Healing Effects of New Membranes Based on Chitosan, Hyaluronic Acid and Arginine Derivatives (2018)

New membranes based on chitosan and chitosan-hyaluronic acid containing new arginine derivatives with thiazolidine-4-one scaffold have been prepared using the ionic cross-linking method. The presence of the arginine derivatives with thiazolidine-4-one scaffold into the polymer matrix was proved by Fourier-transform infrared spectroscopy (FT-IR). The scanning electron microscopy (SEM) revealed a micro-porous structure that is an important characteristic for the treatment of burns, favoring the exudate absorption, the rate of colonization, the cell structure, and the angiogenesis process. The developed polymeric membranes also showed good swelling degree, improved hydrophilicity, and biocompatibility in terms of surface free energy components, which supports their application for tissue regeneration. Moreover, the chitosan-arginine derivatives (CS-6h, CS-6i) and chitosan-hyaluronic acid-arginine derivative (CS-HA-6h) membranes showed good healing effects on the burn wound model induced to rats. For these membranes a complete reepithelialization was observed after 15 days of the experiment, which supports a faster healing process.

Low-Memory Low-Complexity Inverse Dithering (2008)

Dithering an image decreases the pixel bit depth and reduces the storage space required in the image buffer while largely preserving the perceptual quality. In some applications, it is desirable to reconstruct the original image; that is, restore the dithered image to its original bit-depth, for further processing or display. In this paper, we present a new color inverse dithering system designed for low-cost implementation. Our algorithm is based on edge-sensitive adaptive low-pass filtering. In order to prevent excessive blurring from low pass filtering, the system uses edge detection methods so that the filters are applied only to regions of constant color or gray level in the original image. One such method exploits the fact that pixel values are only one level away from each other in a constant color region of a dithered image. Another method exploits a priori knowledge of the dither masks. By limiting the number of possible filters, and by restricting the region of support of the filters to a single image line, tremendous implementation advantages can be gained. Our prototype system uses a set of five filters, including a pair that are asymmetric about the origin specifically for application to object edges. In our implementation, the need for multipliers is eliminated by using bit replication for up-multiplication, and by using lookup tables with relatively small numbers of entries for filtering. We have found that our inverse dithering system can restore to a significant degree a dithered image to its original form. It is especially effective for graphics and synthetic images.
Particle transport studies with applied resonant fields on TEXT (1990)

Externally applied resonant magnetic fields have been used on TEXT to modify the particle flux and the radial electric field near the plasma edge. Magnetic fields with primary mode numbers m/n = 7/3 and 7/2, and an average radial field amplitude ⟨|br|/Bϕ⟩ ≃ 0.1% have been employed. This perturbation produces mixed islands and stochastic regions at the plasma edge (r/a ≥ 0.8) without affecting the interior. Working particle transport is shown to be increased by typically 30% only in the presence of (computed) magnetic islands. The effect is diminished at high perturbing field strength when the islands become stochastic. A novel transport mechanism due to × convection is proposed to explain this. Outward impurity transport is increased as well.
Soccer Events Summarization by Using Sentiment Analysis (2015)

In this paper, we propose a framework for automatic textual soccer summarization based on real-time sentiment analysis of Twitter events. The interaction of fans on Twitter is marked by the expression of their sentiments through their tweets, they can be positive or negative depending on the event in soccer games. Our framework analyzes the sentiments expressed on Twitter with the goal to detect and predict the team supported by each fan as well as actors (the team(s) and player(s) concerned(s)) and the details associated with each event. All this information is used to draw up a summary of soccer matches. The summary is constructed using machine learning and KDD process that allows the extraction of knowledge from data in the context of large databases. Through the realized experiments, we confirm that the results are promising and this work has allowed us to verify the feasibility and efficiency of soccer events summarization by using sentiment analysis in media streams.
p63 sets the threshold for induction of apoptosis using a kinetically encoded ‘doorbell-like’ mechanism (2019)

Abstract Cell fate decisions such as apoptosis require cells to translate signaling input into a binary yes/no response. A tight control of the process is required to avoid loss of cells by accidental activation of cell death pathways. One particularly critical situation exists in primary oocytes because their finite number determines the reproductive capacity of females. On the one hand a stringent genetic quality control is necessary to maintain the genetic integrity of the entire species; on the other hand an overly stringent mechanism that kills oocytes with even minor DNA damage can deplete the whole primary oocyte pool leading to infertility. The p53 homolog TAp63α is the key regulator of genome integrity in oocytes. After DNA damage TAp63α is activated by multistep phosphorylation involving multiple phosphorylation events by the kinase CK1, which triggers the transition from a dimeric and inactive conformation to an open and active tetramer. By measuring activation kinetics in ovaries and single site phosphorylation kinetics in vitro with peptides and full length protein we show that TAp63α phosphorylation follows a biphasic behavior. While the first two CK1 phosphorylation events are fast, the third one that constitutes the decisive step to form the active conformation is slow. We reveal the structural mechanism for the difference in the kinetic behavior based on an unusual CK1/TAp63α substrate interaction and demonstrate by quantitative simulation that the slow phosphorylation phase determines the threshold of DNA damage required for induction of apoptosis.
Characterization of Brucella abortus Soluble Antigen Employed in Immunoassay (1980)

A soluble antigen extract of Brucella abortus (BASA) has been prepared by the National Veterinary Services Laboratories and furnished to a number of workers who are examining antibody-mediated and cell-mediated immune responses of cattle infected with B. abortus. Three lots of BASA were examined. There were quantitative but not qualitative differences among lots by content of protein, total carbohydrate, hexose, fatty acid, and 2-keto-3-deoxyoctonic acid. The presence of smooth lipopolysaccharide was demonstrated by the presence of 2-keto-3-deoxyoctonic acid and lipid, by Limulus lysate gelation activity, and by formation of characteristic lipopolysaccharide precipitates in immunoelectrophoresis. A polysaccharide antigen as well as two nonsurface antigens, A2 and C, were also identified. BASA is a satisfactory antigen for use in the enzyme-linked immunosorbent assay since the smooth lipopolysaccharide component bound to polystyrene and functioned in the test. Normal murine spleen cells showed a mitogenic response to BASA similar to that produced by purified smooth lipopolysaccharide. BASA has been used in other laboratories to stimulate peripheral blood leukocytes from cattle infected with B. abortus. Because BASA is a mixture of antigenic components shown to have mitogenic effects in the mouse system, questions on the nature of its stimulatory effect on bovine cells are raised.
A Fast Algorithm for Deblurring Models with Neumann Boundary Conditions (1999)

Blur removal is an important problem in signal and image processing. The blurring matrices obtained by using the zero boundary condition (corresponding to assuming dark background outside the scene) are Toeplitz matrices for one-dimensional problems and block-Toeplitz--Toeplitz-block matrices for two-dimensional cases. They are computationally intensive to invert especially in the block case. If the periodic boundary condition is used, the matrices become (block) circulant and can be diagonalized by discrete Fourier transform matrices. In this paper, we consider the use of the Neumann boundary condition (corresponding to a reflection of the original scene at the boundary). The resulting matrices are (block) Toeplitz-plus-Hankel matrices. We show that for symmetric blurring functions, these blurring matrices can always be diagonalized by discrete cosine transform matrices. Thus the cost of inversion is significantly lower than that of using the zero or periodic boundary conditions. We also show that the use of the Neumann boundary condition provides an easy way of estimating the regularization parameter when the generalized cross-validation is used. When the blurring function is nonsymmetric, we show that the optimal cosine transform preconditioner of the blurring matrix is equal to the blurring matrix generated by the symmetric part of the blurring function. Numerical results are given to illustrate the efficiency of using the Neumann boundary condition.
Flow Driven by a Torsionally-Oscillating Shrouded Endwall Disk (1997)

A study is made of time-dependent flow of a viscous fluid driven by an oscillating shrouded disk in finite geometry. Numerical solutions to the Navier-Stokes equations are obtained for the flow in a cylindrical cavity with its upper endwall disk executing torsional oscillation at a velocity Ω cos λt. Details of the three-component velocity field are examined at high Reynolds number. The value of the nondimensional amplitude of disk oscillation, ε = Ω/λ, encompasses a range up to ε ≳ O(1). The numerical results for the azimuthal flow for ε ≪ 1 are consistent with the predictions of the earlier analytical model. The azimuthal flow is largely confined to the Stokes layer thickness. The analytical predictions of the meridional flow, based on a straightforward expansion technique, display discrepancies from the numerical results. The steady meridional streaming at finite values of ε is exhibited. The qualitative patterns of meridional steady streaming are verified by laboratory flow visualizations. The explicit effect of Re on the overall flow character is scrutinized. The numerical data are processed to describe the behavior of the torque coefficient at the oscillating disk.
Microwave processing of silicon carbide (1994)

Reaction-bonded silicon carbide ({alpha}-SiC) armor tiles were annealed at 2100{degree}C using microwave radiation at 2.45 GHz. Ultrasonic velocity measurements showed that the longitudinal and shear velocities, acoustic impedances, and acoustic moduli of the post-annealed tiles were statistically higher than for the unannealed tiles. However, the exposed surfaces of the annealed tiles experienced slight degradation, which was attributed to the high annealing temperatures.
