On multi-view active learning and the combination with semi-supervised learning (2008)

Multi-view learning has become a hot topic during the past few years. In this paper, we first characterize the sample complexity of multi-view active learning. Under the α-expansion assumption, we get an exponential improvement in the sample complexity from usual Õ(1/ε) to Õ(log 1/ε), requiring neither strong assumption on data distribution such as the data is distributed uniformly over the unit sphere in Rd nor strong assumption on hypothesis class such as linear separators through the origin. We also give an upper bound of the error rate when the α-expansion assumption does not hold. Then, we analyze the combination of multi-view active learning and semi-supervised learning and get a further improvement in the sample complexity. Finally, we study the empirical behavior of the two paradigms, which verifies that the combination of multi-view active learning and semi-supervised learning is efficient.

Preparation and preliminary evaluation of technetium-99m-labeled fragment E1 for thrombus imaging. (1992)

Fragment E1 labeled with 123I has been previously shown to permit imaging of thrombi in patients within as little as 20 min after injection. Because of the relatively rapid localization and blood disappearance of this protein, 99mTc would be the most clinically acceptable radionuclide for labeling Fragment E1. In this study, human fragment E1 was derivatized with a hydrazino nicotinate function to permit radiolabeling with reduced technetium. The modification reaction was carried out while the fragment E1 was protected in a complex, so that the modification occurred in nonfunctional regions of the fragment E1 molecule. After radiolabeling with 99mTc, the modified fragment E1 retained its functional activity, as judged by its binding to fragment DD in vitro. The ability of 99mTc-fragment E1 to produce images of venous thrombi was demonstrated in animal models. Images were focally positive within 20 min to 1 hr after injection. Thrombus-to-blood ratios exceeded those from 125I-fibrinogen in the same animals. This method of labeling appears to provide an alternative radiolabel to 123I without compromising the function of fragment E1.
B-rep from unregistered multiple range images (2003)

The authors present a method to produce an integrated description of an object given multiple range views without registration. The multiple view representation is in the form of a B-rep (boundary representation). They describe each view of the object as an attributed graph whose nodes are surface patches and links are the relations between surfaces. Any two attributed graphs, each corresponding to a given view, are matched, and the rigid motion transformation between them is computed. The basic strategy for multiple view integration is composed of two aspects: first, a composite graph which contains the bounding surfaces and their corresponding attributes is built and then these surfaces are intersected so that the edges and vertices corresponding to the B-rep description are identified. Results on objects with polyhedral as well as quadratic curved surfaces are presented.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
High Performance Computing Today (2000)

In 1993 for the first time a list of the top 500-supercomputer sites worldwide has been made available. The Top500 list allows a much more detailed and well-founded analysis of the state of high performance computing. This paper summarizes some of the most important observations about HPC as seen through the Top500 statistics. The major trends we document here are the continued dominance of the world market in HPC by the U.S., the completion of a technology transition to commodity microprocessor based highly parallel systems, and the increased industrial use of supercomputers in areas previously no represented on the TOP500 list. The scientific community has long used the Internet for communication of email, software, and papers. Until recently there has been little use of the network for actual computations. The situation is changing rapidly with a number of systems available for performing grid based computing. Keywords High performance computing, Parallel supercomputers, ...
Performance Analysis of Shot Change Detection Methods (2017)

Shot change detection is a significant step in content based video indexing and retrieval. There are different types of transitions between the shots. Most of the shot change detection algorithms deal with these transitions separately. In this paper, we have carried out the analysis of shot change detection methods like pixel difference, histogram difference and Chi-square test and our proposed method. The proposed shot change detection method is integration of pre-processing and KLT (Kanade-Lucas-Tomasi) corner detection technique. In the pre-processing stage, adaptive local thresholding is used to eliminate non-boundary segments and only candidate segments are retained. The candidate segments are refined using bisection-based comparisons to eliminate non-boundary frames. Only refined candidate segments are preserved for further detections; hence, the speed of shot change detection is improved. KLT corner detection approach is used for obtaining key points in the frames from candidate segments. Shot change is detected if the key points between successive frames are not matching. Experimental results indicate that the proposed method is effective in terms accuracy and also helps in accelerating the shot change detection process, which can lead to better and fast retrieval of video.
Comparison of EGF receptor sequences as a guide to study the ligand binding site. (1991)

While murine and human EGF-receptor (EGF-R) bind mammalian EGF with high affinity their chicken counterpart has approximately 300 fold reduced binding affinity towards mammalian EGF. We now cloned and sequenced the extracellular ligand binding domain of murine EGF-R in order to define the amino-acids which comprise the binding site for EGF. Comparison of human, murine and chicken EGF-R allows the identification of amino acid substitutions which are conservative and would not affect EGF binding, substitutions which are responsible for the low affinity binding of EGF to chicken EGF-R and those responsible for the high affinity binding of EGF to mammalian EGF-R. This analysis will enable future design of point mutations in the EGF-R which will restore the high affinity binding for EFG typical of human or murine EGF-R.
Randomization procedures for analyzing clinical trial data with treatment related withdrawals (1990)

The problem of treatment related withdrawals has not been fully addressed in the statistical literature. Statistical procedures which compare efficacies of treatments when withdrawals may occur prior to the conclusion of a study are discussed. A unified test statistic which incorporates all available data, not just the last values and adjusts for withdrawal patterns, proportion of withdrawals, and level of response prior to withdrawal has been developed with the help of data- dependent scoring schemes. A randomization technique has been developed to compute an empirical significance level for each scoring system under both the Fulldata and Endpoint data for a specified parameter configuration. The proposed methods have been applied to a subset (Allen Park Hospital) of the VA study 127.
Theoretical and experimental study of optothermal expansion and optothermal microactuator (2008)

A new type of microactuators based on optothermal (OT) expansion is introduced. The mechanism of the OT expansion is theoretically analyzed, and comprehensive models for OT expansion and bi-direction microactuator are presented in this paper. An expansion arm and a microswitch-like OT microactuator with 1200microm-length are fabricated by an excimer laser micromachining system using single layer material. A laser diode (650nm) is employed as the external power source to activate the arm and the microactuator. Experimental results indicate that the OT expansion increment is approximately linear with the laser power irradiating the expansion arm, coinciding with theoretical predictions quite well. As to the switch-like microactuator, an enlarged bi-direction deflection has been obviously observed. The OT expansion and deflection amplitude that can reach micron scale is generally large enough for most microsystems. The new technique of OT microactuators can be widely applied in those fields where simple structure, easy fabrication, large displacement, wireless and remote controlling are required.
Use of Three-Dimensional Reflectivity Structure for Automated Detection and Removal of Nonprecipitating Echoes in Radar Data (2002)

This study aims at assessing the potential of anomalous propagation conditions to occur, reviews past attempts to mitigate ground clutter contamination of radar data resulting from anomalous signal propagation, and presents a new algorithm for radar data quality control. Based on a 16-yr record of operational sounding data, the likelihood of atmospheric conditions to occur across the United States that potentially lead to anomalous propagation of radar signals is estimated. Anomalous signal propagation may lead to a significant contamination of radar data from ground echoes normally not seen by the radar, which could result in serious rainfall overestimates, if not recognized and treated appropriately. Many different approaches have been proposed to eliminate the problem of regular ground clutter close to the radar and temporary clutter resulting from anomalous signal propagation. None of the reported approaches, however, satisfactorily succeeds in the case of anomalous propagation ground returns embedded in precipitation echoes, a problem that remains a challenge today for radar data quality control. Taking strengths and weaknesses of past approaches into consideration, a new automated procedure has been developed that makes use of the three-dimensional reflectivity structure. In particular, the vertical extent of radar echoes, their spatial variability, and vertical gradient of intensity are evaluated by means of a decision tree. The new algorithm appears to work equally well in situations where anomalous propagation ground returns are either separated from or embedded within precipitation echoes. Moreover, sea clutter echoes are identified as not raining and successfully removed.
Orphan Nuclear Receptors and Their Ligands (1998)

Nuclear hormone receptors constitute a superfamily of related transcription factors that mediate the actions of nuclear-acting hormones including glucocorticoids, mineralocorticoids, estrogens, progestins, androgens, thyroid hormones, vitamin D, and retinoic acid (Mangelsdorf and Evans 1995). As described in earlier chapters of this book, members of this superfamily are characterized by their conserved DNA-binding, ligand-binding, and C-terminal transactivation domain (AF2) (Figure 1). By 1988, nuclear receptors had been identified for all known nuclear acting hormones. It appeared that all members of this superfamily had been identified until Giguere et al (Giguere et al 1988) reported a new and unexpected addition to the nuclear receptor superfamily. Over the next few years this group of receptor-like molecules rapidly expanded and collectively became known as orphan nuclear receptors. Now, almost a decade later, the orphan receptors have expanded to include over 30 distinct mammalian genes (Mangelsdorf et al 1995). As genome sequencing projects continue, it is likely that additional orphan receptors will be identified.
Expression of the extracellular matrix signaling molecule Cyr61 is downregulated in prostate cancer (1998)

Cyr61 is a member of the emerging family of extracellular signaling proteins and enhances the effect of bFGF. The changed pattern of expression Cyr61 might therefore contribute to the altered interactions between epithelial and stromal cells in prostate carcinoma.
Extracting and Predicting Taxi Hotspots in Spatiotemporal Dimensions Using Conditional Generative Adversarial Neural Networks (2020)

It is of practical importance to extract and predict taxi hotspots in urban traffic networks. However, the extraction of taxi hotspot is generally influenced by multiple sources of dependence, which has not been well recognized in the existing literature. This study aims to investigate how the integration of clustering models and deep learning approaches can learn and extract the network-wide taxi hotspots in both temporal and spatial dimensions. A density based spatiotemporal clustering algorithm with noise (DBSTCAN) was established to extract the historical taxi hotspots, which changed with time. A conditional generative adversarial network with long short-term memory structure (LSTM-CGAN) model was proposed for taxi hotspot prediction, which is capable of capturing the spatial and temporal variations of taxi hotspots simultaneously. Specifically, the DBSTCAN was applied to process the large-scaled geo-coded taxi pickup data into time-varying historical hotspot information. The proposed LSTM-CGAN model was then trained by the network-wide hotspot data. As illustrated in the numerical tests, it was found that the proposed LSTM-CGAN model provided comparable results with different model layouts and model with 4 LSTM layers in both generator and discriminator performed best. Moreover, four typical prediction approaches were selected to compare with the proposed LSTM-CGAN model. The comparative analyses showed that the proposed LSTM-CGAN model reduced the false positive rate from 5.20% to 0.56% and the false negative rate from 63.50% to 39.93%, and improved the section consistency from 41.78% to 73.43% and the area under the curve from 0.670 to 0.969. The comparison results indicated that the proposed LSTM-CGAN model outperformed all these benchmark methods and demonstrated great potential to enable many shared mobility applications.
Potential Elevation Shift of the European Beech Stands (Fagus sylvatica L.) in Serbia (2019)

According to climate projection models, the global temperature is expected to rise by at least 1.5°C by the end of this century. According to some studies the expected rise in Serbia is even higher. Global warming may result in creating new areas for forest growth. Although creating new forests would be a positive outcome in some areas, global warming can cause negative impacts in other areas, and this can lead to forest loss and the shift of geographical ranges, or even extinction, of plant species. The European beech is the dominant forest tree species in Serbia, featuring high ecological importance and economic value. In mixed or pure stands, beech forests cover approximately 660,400 ha, accounting for 29.3% of the total Serbian forest area. In the present study, the effects of climate change on the distribution of the European beech stands in Serbia, with an emphasis on their elevation shifts, were examined using species distribution models (SDMs). Data for the present tree cover in Serbia, climate projections, and environmental data were used for model building. The models were first tested against present inventory data. In these tests, the models were found to provide accurate projections, as shown by their true skills statistics (TSS) values ranging from 0.652 to 0.736 and area under the curve (AUC) values ranging from 0.868 to 0.937. The potential distribution patterns predicted by the models indicate that the European beech elevational distribution in Serbia would decrease, exhibiting a significant upward shift in elevation during the first part of this century. Current beech stand locations could be changed, and other areas at higher elevations may be more suitable for beech growth. After 2071, European beech stands at elevations below 500 m would be even smaller. This change is caused by temperature rise and occurrence of climate extremes. However, on the highest elevations, further upward shift of the species is not expected.
Plasma Etching of Tungsten Polycide Structures Using  NF 3 ‐ Mixed Halocarbon Etchants (1991)

The feasibility of utilizing halocarbon etchants to anisotropically etch tungsten polycide structures has been investigated. Chemical vapor deposited tungsten silicide and low‐pressure chemical vapor deposited polysilicon have been etched using various mixtures of , , and with . Anisotropy, undercutting, and notching were evaluated using cross‐sectional scanning electron microscopy. Etch rates and profiles were controlled by utilizing halocarbon‐rich (>50%) binary halocarbon etchants. The etch rate data indicate that the volatility of the tungsten halide formed during etching influences the silicide etch rate and profile while the polymer forming ability of the halocarbon controls the etch characteristics of the polysilicon.
Spontaneous preterm labor is associated with an increase in the proinflammatory signal transducer TLR4 receptor on maternal blood monocytes (2010)

Patients with preterm labor exhibited elevated levels of CD14+ maternal blood monocytes each bearing enhanced expression of TLR4, indicating that the peripheral circulatory system is activated in patients with preterm labor. Elevated leukocyte TLR4 levels may be a useful biomarker associated with preterm labor.
A novel forecasting model of contaminated insulator flashover voltage (2009)

To solve the problem of the selecting of the external insulation under complex circumstance conditions, a flashover voltage forecasting model of contaminated insulators based on double ANNs is proposed in the paper. The equivalent salt deposit density (ESDD) is the key of flashover voltage on contaminated insulator, and circumstance conditions are also great influence on it. The equivalent salt deposit density (ESDD) value of insulator can be treated as a nonlinear time series and be forecasted by the nonlinear time series ANNs model. The flashover voltage forecasting model consists of two artificial neural networks. The first is used to forecast the equivalent salt deposit density (ESDD) time series and the second is employed to calculate the withstand voltage of insulator. A series of artificial pollution tests show that the results of the forecasting model is acceptable in engineering application.

The pixel size is 200 /spl times/ 200 /spl mu/m/sup 2/, the active area is 6.4 /spl times/ 6.4 mm/sup 2/. The successful operation of this high-Z imaging pixel device is demonstrated. Noise and threshold dispersion as well as the imaging performance are reported.
Assessing walking disability in multiple sclerosis (2012)

Most patients with multiple sclerosis (MS) eventually experience walking disability. The objective of this review was to evaluate the clinical utility of measures specific for walking in MS. Walking assessments had high reliability and were correlated with related measures, including the 12-item multiple sclerosis walking scale (MSWS-12). Shorter timed walking tests (Timed 25-foot Walk (T25FW), 10-metre Timed Walk, 30-metre Timed Walk) measure overall walking disability and are best suited for clinical settings, whereas longer timed or distance tests (100-metre Timed Walk, 6-minute Walk Test, 2-minute Walk Test) are better for the assessment of walking fatigability, distance limitations and functional capacity. The MSWS-12 measures different, but related, aspects of walking than the objective tests. The T25FW is the best characterised objective measure of walking disability and can be used across a wide range of walking disabilities. Additional work is needed to fully characterise the other objective walking assessments in MS.

Least-squares image resizing using finite differences (2001)

We present an optimal spline-based algorithm for the enlargement or reduction of digital images with arbitrary (noninteger) scaling factors. This projection-based approach can be realized thanks to a new finite difference method that allows the computation of inner products with analysis functions that are B-splines of any degree n. A noteworthy property of the algorithm is that the computational complexity per pixel does not depend on the scaling factor a. For a given choice of basis functions, the results of our method are consistently better than those of the standard interpolation procedure; the present scheme achieves a reduction of artifacts such as aliasing and blocking and a significant improvement of the signal-to-noise ratio. The method can be generalized to include other classes of piecewise polynomial functions, expressed as linear combinations of B-splines and their derivatives.
