Geometric design alternatives for topographical 3D maps inspired by hand-painted panoramas (2011)

When creating digital topographic 3D maps, mapmakers encounter a number of challenges related to\nocclusion, foreshortening and viewpoint selection. In this paper, we present methods to geometrically\ndeform 2.5D digital elevation models to mitigate such problems. Our methods are inspired by manual\ntechniques of panorama painters. Our algorithms allow the cartographer to interactively apply global\nprogressive and local deformation to a digital terrain model. To demonstrate our methods, we present a\nseries of digital 3D maps that imitate a hand-painted panorama.
Enhanced oxidative stress impairs cAMP-mediated dilation by reducing K<sub>v</sub> channel function in small coronary arteries of diabetic rats (2005)

We have shown that short-term exposure of rat small coronary arteries (RSCAs) to high glucose enhances superoxide (O 2 − ·) formation and impairs cAMP-mediated dilation by reducing voltage-gated K + (K v ) channel function. However, it is not clear whether the impairment also occurs in diabetes mellitus (DM), where alternate mechanisms could mask or aggravate vasodilator dysfunction. RSCAs were isolated from control and streptozotocin-induced diabetic rats. Reduced constriction to 4-aminopyridine (4-AP) was observed in RSCAs from DM rats, indicating K v channel impairment. Forskolin increased 4-AP-inhibitable K + channel open-state probability and whole cell K + current density in coronary myocytes from non-DM rats but had little effect on K + current density in cells from DM rats. Diminished dilation to 8-bromo-cAMP, forskolin, or isoproterenol was observed in DM RSCAs. The attenuated dilation to forskolin or isoproterenol in DM RSCAs was partially restored by application of the superoxide dismutase mimetic manganese[III] tetrakis (4-benzoic acid) porphyrin. Histofluorescence studies using hydroethidine revealed a blockage of O 2 − · generation by the NADPH oxidase inhibitor apocynin in DM RSCAs. Sepiapterin, a precursor of tetrahydrobiopterin, had little effect on hyperglycemia-induced O 2 − · formation. Consistent with the findings from the concurrent fluorescence study, apocynin also partially restored the reduced dilator response to forskolin in DM RSCAs. Forskolin-induced cAMP production was unaltered in DM. We conclude that in diabetes, enhanced O 2 − · formation by activation of NADPH oxidase impairs cAMP-medicated dilation in RSCAs by inhibiting K v channel activity.
Computer control of fiber Bragg grating spectral characteristics using a thermal head (1997)

We present a new technique for arbitrarily controlling the temperature distribution in fiber Bragg gratings (FBG's) to control their spectral characteristics. A thermal head consisting of a microheater array, driven with computer control signals is used as a controlling device. Various spectral characteristics including a chirped grating and a transmission filter are demonstrated using a single unchirped grating. An effective improvement in response time constant of thermal control was observed on bonding of the fiber grating to thermal head (18 ms), in comparison to that without bonding (40 ms). The measured results did not show any hysterisis. Reliability studies of this technique are also reported. The same technique is further used for the dual wavelength operation of an Er-doped fiber laser.

GiMMiK—Generating bespoke matrix multiplication kernels for accelerators: Application to high-order Computational Fluid Dynamics (2016)

Matrix multiplication is a fundamental linear algebra routine ubiquitous in all areas of science and engineering. Highly optimised BLAS libraries (cuBLAS and clBLAS on GPUs) are the most popular choices for an implementation of the General Matrix Multiply (GEMM) in software. In this paper we present GiMMiK—a generator of bespoke matrix multiplication kernels for the CUDA and OpenCL platforms. GiMMiK exploits a prior knowledge of the operator matrix to generate highly performant code. The performance of GiMMiK's kernels is particularly apparent in a block-by-panel type of matrix multiplication, where the block matrix is typically small (e.g. dimensions of 96×64). Such operations are characteristic to our motivating application in PyFR—an implementation of Flux Reconstruction schemes for high-order fluid flow simulations on mixed unstructured meshes. GiMMiK fully unrolls the matrix–vector product and embeds matrix entries directly in the code to benefit from the use of the constant cache and compiler optimisations. Further, it reduces the number of floating-point operations by removing multiplications by zeros. Together with the ability of our kernels to avoid the poorly optimised cleanup code, executed by library GEMM, we are able to outperform cuBLAS on two NVIDIA GPUs: GTX 780 Ti and Tesla K40c. We observe speedups of our kernels over cuBLAS GEMM of up to 9.98 and 63.30 times for a 294×1029 99% sparse PyFR matrix in double precision on the Tesla K40c and GTX 780 Ti correspondingly. In single precision, observed speedups reach 12.20 and 13.07 times for a 4×8 50% sparse PyFR matrix on the two aforementioned cards. Using GiMMiK as the matrix multiplication kernel provider allows us to achieve a speedup of up to 1.70 (2.19) for a simulation of an unsteady flow over a cylinder executed with PyFR in double (single) precision on the Tesla K40c. All results were generated with GiMMiK version 1.0.
Information Systems for Risk Management (1997)

Risk management information systems are designed to overcome the problem of aggregating data across diverse trading units. The design of an information system depends on the risk measurement methodology that a firm chooses. Inherent in the design of both a risk management information system and a risk measurement methodology is a tradeoff between the accuracy of the resulting measures of risk and the burden of computing them. Technical progress will make this tradeoff more favorable over time, leading firms to implement more accurate methodologies, such as full revaluation of nonlinear positions. The current and likely future improvements in risk management information systems make feasible new ways of collecting aggregate data on firms' risk-taking activities.
Reductive Dechlorination of <i>cis</i>-1,2-Dichloroethene and Vinyl Chloride by “<i>Dehalococcoides ethenogenes</i>” (2000)

cis-Dichloroethene (DCE) and vinyl chloride (VC) often accumulate in contaminated aquifers in which tetrachloroethene (PCE) or trichloroethene (TCE) undergo reductive dechlorination. "Dehalococcoides ethenogenes" strain 195 is the first isolate capable of dechlorinating chloroethenes past cis-DCE. Strain 195 could utilize commercially synthesized cis-DCE as an electron acceptor, but doses greater than 0.2 mmol/L were inhibitory, especially to PCE utilization. To test whether the cis-DCE itself was toxic, or whether the toxicity was due to impurities in the commercial preparation (97% nominal purity), we produced cis-DCE biologically from PCE using a Desulfitobacterium sp. culture. The biogenic cis-DCE was readily utilized at high concentrations by strain 195 indicating that cis-DCE was not intrinsically inhibitory. Analysis of the commercially synthesized cis-DCE by GC/mass spectrometry indicated the presence of approximately 0.4% mol/mol chloroform. Chloroform was found to be inhibitory to chloroethene utilization by strain 195 and at least partially accounts for the inhibitory activity of the synthetic cis-DCE. VC, a human carcinogen that accumulates to a large extent in cultures of strain 195, was not utilized as a growth substrate, and cultures inoculated into medium with VC required a growth substrate, such as PCE, for substantial VC dechlorination. However, high concentrations of PCE or TCE inhibited VC dechlorination. Use of a hexadecane phase to keep the aqueous PCE concentration low in cultures allowed simultaneous utilization of PCE and VC. At contaminated sites in which "D. ethenogenes" or similar organisms are present, biogenic cis-DCE should be readily dechlorinated, chloroform as a co-contaminant may be inhibitory, and concentrations of PCE and TCE, except perhaps those near the source zone, should allow substantial VC dechlorination.
Measurement of the temperature distribution in fluids using ultrasonic tomography (1994)

This paper describes the non-invasive measurement of the distributed temperature in liquid using an ultrasound time-of-flight technique. The system uses eight piezoelectric transducers mounted circumferentially inside a pipe of diameter 300 mm. A reconstruction method was used to evaluate the temperature distribution within the plane of the transducers. The method is based on the approximation of the inverse function of the velocity of ultrasonic propagation by the linear combination of discrete and polynomial basis functions. A modified Gauss method is used solve the equations. The reasons for the non-uniform measurement path density is discussed
Stimulation of simian virus 40 late gene expression by simian virus 40 tumor antigen. (1984)

The early simian virus 40 (SV40) gene product, large tumor (T) antigen, is responsible for the initiation of viral DNA replication and the autoregulation of early gene expression through direct protein-DNA interactions. We investigated the role of T antigen in late viral gene expression, independent of its function in amplifying templates through DNA replication. SV40 DNA was transfected into BSC-1 and COS-1 cells and cultured in the presence of inhibitors of DNA replication. Electrophoretic immunoblot analysis indicated that both the onset and the extent of SV40 late gene expression is increased in COS-1 cells, which constitutively express SV40 T antigen. Blot hybridization analysis of poly(A)-selected RNA demonstrated that the level of synthesis of the major late structural protein VP-1 in COS-1 cells was due to increased transcription. Similar results were obtained when plasmids that contain the SV40 late gene but lack both the origin for viral DNA replication and the early gene coding region were transfected onto COS-1 cells. Using lines of SV40-transformed monkey kidney cells that express altered T antigens, we found that enhanced expression of the late gene product is correlated with the ability of T antigen to bind SV40 DNA. These results indicate that large T antigen plays a role in the stimulation of late viral gene expression.
Using probabilistic approach to joint clustering and statistical inference: Analytics for big investment data (2015)

This paper proposes a Contrarian Probabilistic Model (CPM) to evaluate the effectiveness of contrarians' investment in preferred stocks using big data from Tradeline. CPM accommodates the unique features of investment data which are often correlated, nested, heterogeneous, non-normal with missing values. The clustering and statistical inference are integrated in CPM, which enables joint investment behavior trajectory pattern recognition and risk analyses based on the entire variance-covariance structure between and within clusters. The empirical study using CPM provides a finer and comprehensive evaluation of contrarian investment in preferred stocks. Two distinctive investment behavior trajectory clusters were identified, showing a few high-risk-seeking contrarians achieved high returns over five year long-term investment, while the majority of contrarians did not outperform glamour stockholders in preferred stock investment. Although CPM was developed using historical data, it could be developed into an analytical tool for online near real time big investment data analyses.
Magnetically induced super resolution in a novel magneto-optical disk (1991)

A super resolution has been achieved in the magneto-optical disk using an exchange-coupled multilayer film. Two types of magnetically induced super resolution, front aperture detection and rear aperture detection have been successfully investigated. A high C/N of more than 42 dB is obtained experimentally for a mark length of 0.3 micrometers which is much shorter than the resolution limit expected from the conventional diffraction theory.

Post-Antibiotic Effect of FK-037 and Biapenem Tested against Five Bacterial Species (1994)

The in-vitro post-antibiotic effect (PAE) was determined for two newer beta-lactams, FK-037 (a cephalosporin) and biapenem (a carbapenem). Our PAE results for these drugs were consistent with what has been reported previously for similar beta-lactams, e.g. Gram-positive organisms had measurable effects (0.4-2.2 hours), while Gram-negatives had variable results (0.0 to 1.4 hours). Even though the PAE test conditions generally coincided with achievable clinical levels for most organisms tested (< or = 4 mg/L for biapenem and < or = 8 mg/L for FK-037), the marginal or species dependent, short PAE values support the selection of multiple daily doses (two-to-four) based on conventional pharmacokinetic parameters such as the Cmax, AUC, and serum elimination half-life.
Population (1998)

The principal sources of population data are official censuses, administrative enumerations, and registration records. For many countries in Africa, and some in Asia, these only began in the twentieth century, often only after the Second World War; and the quality of their coverage has not always been particularly good. Historical coverage of different countries, therefore, varies widely in scope and reliability. Table A1 gives the statistics from all the censuses and official enumerations which have been conducted in these two continents and Oceania which were in their intention complete.1 But since to restrict the table to these alone would provide no data at all for certain countries, and very little for others, the results of certain more-or-less official estimations have been included where these seem likely to be reasonably reliable.KeywordsHistorical StatisticsEarly EstimateChinese CityDemographic YearbookOfficial CensusThese keywords were added by machine and not by the authors.

Low temperature processing of sol-gel derived PLZT thin film (1999)

Abstract Sol-gel derived lanthanum-modified lead zirconate titanate (PLZT) thin films with La/Zr/Ti ratio of 10/65/35 were deposited on indium tin oxide (ITO)-coated soda lime glass substrate. Effects of excess lead addition of 30 mol% in the precursor solution and/or insertion of a lead lanthanum titanate (PLT) film as a seeding layer between ITO and PLZT films on the crystallization behavior of the resultant PLZT thin films were investigated by X-ray diffraction. As a result, single phase perovskite films with good ferroelectricity were successfully deposited at 500°C. In addition, the resultant PLZT films showed more than 60% of transmittance in visible region.
Vibration suppression of induction-motor-driven hybrid vehicle using wheel torque observer (1992)

The authors describe the vibration phenomenon occurring in indirect field-oriented control or vector control when induction motors drive inertia load through a spring under overload at high speed. The target system of this study is a hybrid vehicle consisting of a front engine-driven system and two rear motor-driven systems, which are designed to improve the driving stability. In this vehicle, violent vibrations occur when the induction motors drive under strict conditions of overload at high speed. The stability analysis and a mechanical system, revealed that the vector control system is essentially unstable under extreme overload and demagnetization when the induction motor loads the power train. Therefore, suppression of vibrations was attempted using an observer for estimating wheel torque and a regulator for state feedback from the outside of the vector control system. These methods suppressed the vibration well enough to drive under overload at high speed.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

Control of respiration and bioenergetics during muscle contraction (2004)

(1)H-NMR experiments have determined intracellular O(2) consumption (Vo(2)) with oxymyoglobin (MbO(2)) desaturation kinetics in human calf muscle during plantar flexion exercise at 0.75, 0.92, and 1.17 Hz with a constant load. At the onset of muscle contraction, myoglobin (Mb) desaturates rapidly. The desaturation rate constant of approximately 30 s reflects the intracellular Vo(2). Although Mb desaturates quickly with a similar time constant at all workload levels, its final steady-state level differs. As work increases, the final steady-state cellular Po(2) decreases progressively. After Mb desaturation has reached a steady state, however, Vo(2) continues to rise. On the basis of current respiratory control models, the analysis in the present report reveals two distinct Vo(2) phases: an ADP-independent phase at the onset of contraction and an ADP-dependent phase after Mb has reached a steady state. In contrast to the accepted view, the initial intracellular Vo(2) shows that oxidative phosphorylation can support up to 36% of the energy cost, a significantly higher fraction than expected. Partitioning of the energy flux shows that a 31% nonoxidative component exists and responds to the dynamic energy utilization-restoration cycle (which lasts for only milliseconds) as postulated in the glycogen shunt theory. The present study offers perspectives on the regulation of respiration, bioenergetics, and Mb function during muscle contraction.
Power consumption prediction of submerged arc furnace based on multi-input layer wavelet neural network (2010)

Two-input layer wavelet neural network prediction model is established, through the analysis of the smelting process of submerged arc furnace and combining of wavelet analysis and neural network theory, used to predict the power consumption of the submerged arc furnace timely. The input variables are not input in one layer, but in different layers according to their action sequences,thereby reducing the scale of the network. Then the genetic algorithm (GA) is used to optimize the weights of neural network, thus achieve the purpose of global optimization and fast convergence speed. The validity of the method mentioned can be proved by simulation and the experiment result.
DYNAMIC VOLTAGE SCALING FOR PRIORITY-DRIVEN SCHEDULED DISTRIBUTED REAL-TIME SYSTEMS (2007)

Energy consumption is increasingly affecting battery life and cooling for real- time systems. Dynamic Voltage and frequency Scaling (DVS) has been shown to substantially reduce the energy consumption of uniprocessor real-time systems. It is worthwhile to extend the efficient DVS scheduling algorithms to distributed system with dependent tasks. The dissertation describes how to extend several effective uniprocessor DVS schedul- ing algorithms to distributed system with dependent task set. Task assignment and deadline assignment heuristics are proposed and compared with existing heuristics concerning energy-conserving performance. An admission test and a deadline com- putation algorithm are presented in the dissertation for dynamic task set to accept the arriving task in a DVS scheduled real-time system. Simulations show that an effective distributed DVS scheduling is capable of saving as much as 89% of energy that would be consumed without using DVS scheduling. It is also shown that task assignment and deadline assignment affect the energy- conserving performance of DVS scheduling algorithms. For some aggressive DVS scheduling algorithms, however, the effect of task assignment is negligible. The ad- mission test accept over 80% of tasks that can be accepted by a non-DVS scheduler to a DVS scheduled real-time system.
