Study on model of support vector machine for synthetic prediction of seismic precursors (2008)

The principle of support vector machine (SVM) and its regression algorithm is introduced in this paper. The multidimensional samples from theoretical formula are tested by using of SVM. The best model for synthetic prediction of seismic precursors is established according to the SVM algorithm and the seismic precursory anomalies, and it is tested by using of the testing samples. It indicates that the forecast result of the best mode and earthquake magnitude of real seismic examples are basically consistent. It shows that the support vector machine algorithm has an obvious superiority whatever on machine learning or prediction accuracy, and the model for synthetic prediction of seismic precursors based on the SVM theory is feasible, and it can forecast the magnitude of main earthquakes more accurately.
Clay/latex mixture stops lost circulation in large carbonate fractures (1995)

A mixture of latex and drilling mud clay controls lost circulation in large carbonate fractures by coagulating when it mixes with the formation fluids. The mixture forms large aggregates capable of plugging large formation fractures and is not prone to being washed out by formation water. The Scientific Research Institute of Drilling Techniques in Moscow (Vniibt) has developed a special lost circulation mixture combining a latex base and clay drilling mud for use in plugging these fractures. Mud powders of bentonite and calcium clays can be used to prepare the clay-latex mixture (GPC). The latex is mixed with drilling mud made from bentonite clay powder and is pumped to the lost circulation zone where it coagulates by reacting with the calcium ions in the formation water. The latex used to prepare GPC must be compatible with the mud being used. After coagulation, GPC changes to a rubber mixture. In the Tataria oil region, one of the drilling enterprises used GPC in 23 wells, with positive results in 20 of the wells. The bentonite powder base GPC mixture remains easily pumpable until the end of the operation. The mixture`s plastic strength increases over time as it is pumped into the lostmore » circulation zone. This type of mixture is typically used to control lost circulation at depths greater than 1,000--1,500 m. GPC based on drilling mud made from calcium clay is used at shallower depths. For GPC pumped into a borehole, the latex/clay drilling mud ratio is typically between 1:1 and 1:2.« less
A Model-Based Regression Testing Approach for Evolving Software Systems with Flexible Tool Support (2010)

Model-based selective regression testing promises reduction in cost and labour by selecting a subset of the test suite corresponding to the modifications after system evolution. However, identification of modifications in the systems and selection of corresponding test cases is challenging due to interdependencies among models. State-based testing is an important approach to test the system behaviour. Unfortunately the existing state-based regression testing approaches do not care for dependencies of the state machines with other system models. This paper presents the tool support and evaluation of our state-based selective regression testing methodology for evolving state-based systems. START is an Eclipse-based tool for state-based regression testing compliant with UML 2.1 semantics. START deals with dependencies of state machines with class diagrams to cater for the change propagation. We applied the START on a case study and our results show significant reduction in the test cases resulting in reduction in testing time and cost.
Anti-human Activin Receptor-like Kinase 1 (ALK1) Antibody Attenuates Bone Morphogenetic Protein 9 (BMP9)-induced ALK1 Signaling and Interferes with Endothelial Cell Sprouting (2012)

Genetic and molecular studies suggest that activin receptor-like kinase 1 (ALK1), a transforming growth factor β (TGF-β) type I receptor and endoglin, a TGF-β co-receptor, play an essential role in vascular development and pathological angiogenesis. Several agents that interfere with ALK1 and endoglin function are currently in clinical trials for anti-angiogenic activity in cancer therapy. One of these agents, PF-03446962 (anti-hALK1 antibody), shows promising results in the clinic. However, its effects on endothelial cell function and mechanism of action are unclear. Here we demonstrate that anti-hALK1 antibody selectively recognizes human ALK1. The anti hALK1-antibody interfered with bone morphogenetic protein 9 (BMP9)-induced signaling in endothelial cells. Consistent with this notion, anti-hALK1 antibody was found to compete highly efficiently with the binding of the ALK1 ligand BMP9 to ALK1. Moreover, it prevented BMP9-dependent recruitment of co-receptor endoglin into this angiogenesis-mediating signaling complex. In addition, we demonstrated that anti-hALK1 antibody inhibited endothelial cell sprouting, but did not directly interfere with vascular endothelial growth factor (VEGF) signaling, VEGF-induced proliferation and migration of endothelial cells. Finally, we demonstrated that BMP9 in serum is essential for endothelial sprouting and that anti-hALK1 antibody inhibits this potently. Our data suggest that both the VEGF-VEGFR and the BMP9-ALK1 pathways are essential for stimulating angiogenesis, and targeting both pathways simultaneously is an attractive strategy to overcome resistance to anti-angiogenesis therapy.
Slap Fingerprint Segmentation for Live-Scan Devices and Ten-Print Cards (2010)

Presented here is a highly accurate and computationally efficient algorithm suitable for slap fingerprint segmentation. The main advantages of this algorithm are as follows: 1)three-order cumulant is used to roughly segment the foreground; 2)frequency domain analysis is carried out in local areas to do binarization and fine segmentation; 3)cumulative sum analysis is applied to extract the knuckle lines; 4)two shape features of the ellipse are adapted to calculate the confidence of each fingertip candidate. Experimental results show that the algorithm has the characteristic of more robustness against noise and superior precision, not only for live-scan four finger slaps but also for ten-print-card five finger slaps.
Modulated Magnetic Nanowires for Controlling Domain Wall Motion: Toward 3D Magnetic Memories (2016)

Cylindrical magnetic nanowires are attractive materials for next generation data storage devices owing to the theoretically achievable high domain wall velocity and their efficient fabrication in highly dense arrays. In order to obtain control over domain wall motion, reliable and well-defined pinning sites are required. Here, we show that modulated nanowires consisting of alternating nickel and cobalt sections facilitate efficient domain wall pinning at the interfaces of those sections. By combining electron holography with micromagnetic simulations, the pinning effect can be explained by the interaction of the stray fields generated at the interface and the domain wall. Utilizing a modified differential phase contrast imaging, we visualized the pinned domain wall with a high resolution, revealing its three-dimensional vortex structure with the previously predicted Bloch point at its center. These findings suggest the potential of modulated nanowires for the development of high-density, three-dimensional data storage devices.

ScaleStar: Budget Conscious Scheduling Precedence-Constrained Many-task Workflow Applications in Cloud (2012)

Traditionally, the "best effort, cost free" model of Supercomputers/Grids does not consider pricing. Clouds have progressed towards a service-oriented paradigm that enables a new way of service provisioning based on "pay-as-you-go" model. Large scale many-task workflow (MTW) may be suited for execution on Clouds due to its scale-* requirement (scale up, scale out, and scale down). In the context of scheduling, MTW execution cost must be considered based on users' budget constraints. In this paper, we address the problem of scheduling MTW on Clouds and present a budget-conscious scheduling algorithm, referred to as ScaleStar (or Scale-*). ScaleStar assigns the selected task to a virtual machine with higher comparative advantage which effectively balances the execution time-and-monetary cost goals. In addition, according to the actual charging model, an adjustment policy, refer to as DeSlack, is proposed to remove part of slack without adversely affecting the overall makespan and the total monetary cost. We evaluate ScaleStar with an extensive set of simulations and compare with the most popular HEFT-based LOSS3 algorithm and demonstrate the superior performance of ScaleStar.
Nonlinear magnetic vortex gyration (2012)

Nonlinear motion of magnetic vortices in soft magnetic squares is investigated by micromagnetic simulations, analytical calculations, and broadband ferromagnetic resonance measurements. Increasing amplitudes of alternating unidirectional spin currents and magnetic fields cause the shapes of the trajectories to approach the shape of the sample and shift the resonance frequency of vortex gyration. We show that it is the thickness of the magnetic element that determines whether the resonance frequency shifts to the red or to the blue. A nonlinear equation of motion based on the Thiele equation reproduces the simulated and measured results.
Potential formation of intramolecular inclusion complexes in peptido-cyclodextrins as evidenced by NMR spectroscopy (1995)

Investigations of the structure of β- and γ-cyclodextrin derivatives in solution obtained by grafting amino acids or peptides are presented. These compounds are models for vectorization-dedicated molecular carriers. It is shown that for some amino acids, strong intramolecular self inclusion complexes are formed in aqueous solution. This process strongly depends upon the nature and position of the pertinent amino acid in the peptide sequence. Two dimensional NMR experiments are used in conjunction with competition with external guests to evidence and estimate the strength of these auto-inclusion complexes.
[Testing of the "retinal acuity" with the laser interference apparatus as a routine clinical method]. (1977)

<p>Both the sustainable development of China's economy and the deregulation of the China air transport market have acted as a spur for the halting development of low-cost carriers (LCCs) in China. To analyze the development trends of LCCs' network in China, this paper took Spring Airlines, the only LCC in China as an example. First, the winter flight plans of Spring Airlines from 2005 to 2013 were collected. Secondly, the development trends of air transport network of Spring Airlines were explored with methods of mathematical statistics and social network analysis. Additionally, the development trends were analyzed from the levels of navigable cities, air routes and air transport networks. The results show that although Spring Airlines actively launched air routes between tourist cities with non-class I airports, its network has been transformed from a star structure into a complex one with multi-hubs. The development process of the Spring Airlines network can be separated into three stages. In addition, the problems and evolution trends of its network are discussed further.</p>
GA-based control of a robot manipulator in a foundry workcell (2014)

In this paper, a method is presented to simulate the performance of an industrial robot manipulator in a foundry workcell. The robot under consideration is IRB 6640 180-2.55 from ABB used for handling heavy cores in ElectroSteel Castings Ltd., Kolkata. The proposed method considers the time-optimal control of robot motion to simulate the actual behavior of the robot. A model-based control technique is applied to control the robot's end-effector motion. Genetic Algorithm (GA) is implemented to optimize the gains in the proposed control method. Points used for defining the required path are taken from the actual program running in the workcell. Parameters needed to construct robot kinematic and dynamic models and constraints on robot motion are extracted from robot manuals and simulations on the same robot in ABB RobotStudio <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">®</sup> environment.

Optical gain and gain suppression of quantum-well lasers with valence band mixing (1990)

The effects of valence band mixing on the nonlinear gains of quantum-well lasers are studied theoretically for the first time. The analysis is based on the multiband effective-mass theory and the density matrix formalism with intraband relaxation taken into account. The gain and the gain-suppression coefficient of a quantum-well laser are calculated from the complex optical susceptibility obtained by the density matrix formulation with the theoretical dipole moments obtained from the multiband effective-mass theory. The calculated gain spectrum shows that there are differences (both in peak amplitude and spectral shape) between this model with valence band mixing and the conventional parabolic band model. The shape of the gain spectrum calculated by the new model becomes more symmetric due to intraband relaxation together with nonparabolic energy dispersions. Optical intensity in the GaAs active region is estimated by solving rate equations for the stationary states with nonlinear gain suppression.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Induction of urokinase-type plasminogen activator by the anthracycline antibiotic in human RC-K8 lymphoma and H69 lung-carcinoma cells (2001)

Current evidence has suggested the possible involvement of ROS as signaling messengers in IL-1beta- or LPS-induced gene expression. We previously reported that both IL-1beta and LPS induce uPA in RC-K8 human lymphoma cells. Here, we provide evidence that ROS-generating anthracycline antibiotics, including doxorubicin and aclarubicin, upregulate uPA expression in 2 human malignant cell lines, RC-K8 and H69 small-cell lung-carcinoma cells. Both doxorubicin and aclarubicin markedly increased uPA accumulation in RC-K8- and H69-conditioned medium in a dose-dependent manner. In each case, maximal induction was observed at a sublethal concentration, i.e., at a concentration where cell growth was slightly inhibited. Both doxorubicin and aclarubicin increased uPA mRNA levels, and induction in each case reached the maximal level 9 hr after stimulation. Doxorubicin barely changed the half-life of uPA mRNA and activated uPA gene transcription. Antioxidants such as NAC and PDTC inhibited doxorubicin-induced uPA mRNA accumulation. Microarray analysis, using Human Cancer CHIP version 2 (Takara Shuzo, Kyoto, Japan), in which 425 human cancer-related genes were spotted on glass plates, revealed that uPA is 1 of 3 genes that were clearly upregulated in H69 cells by doxorubicin stimulation. These findings suggest that the anthracycline induces uPA in human malignant cells by activating gene transcription in which ROS may be involved. Therefore, by upregulating uPA expression, the anthracycline may influence many biologic cell functions mediated by the uPA/plasmin system.
Palladium nanoparticles supported in a polymeric membrane: an efficient phosphine-free “green” catalyst for Suzuki–Miyaura reactions in water (2014)

Palladium(0) nanoparticles supported on a polymeric membrane, CA/Pd(0), were found to be a highly efficient “dip catalyst” (heterogeneous catalyst) for Suzuki–Miyaura cross-coupling reactions.
Trans-activation of EphA4 and FGF receptors mediated by direct interactions between their cytoplasmic domains (2005)

A yeast two-hybrid analysis has shown that the juxtamembrane region of FGF receptor 3 (FGFR3) interacts with the cytoplasmic domain of EphA4, which is a member of the largest family of receptor tyrosine kinases. Complex formation between the two receptors was shown to be mediated by direct interactions between the juxtamembrane domain of FGFR1, FGFR2, FGFR3, or FGFR4 and the N-terminal portion of the tyrosine kinase domain of EphA4. Activation of FGFR1 in transfected cells resulted in tyrosine phosphorylation of a kinase-negative EphA4 mutant and activation of EphA4 led to tyrosine phosphorylation of a kinase-negative FGFR1 mutant. Moreover, both receptors stimulate tyrosine phosphorylation of the docking protein FRS2alpha and induce mitogen-activated protein kinase stimulation with a time course and intensity that depends on the ligand that is applied. We also demonstrate that FGF-receptor-mediated mitogen-activated protein kinase stimulation is potentiated in cells costimulated with ephrin-A1. The direct interaction between EphA4 and FGFRs and the potentiation of FGF response that is induced by ephrin-A1 stimulation may modulate the biological responses that are mediated by these receptor families in cells or tissues in which the two receptors are coexpressed.
Anticorps anti-CTLA-4 (2011)

The anti-CTLA-4 Mab ipilimumab is an efficient treatment of metastatic melanoma as a single agent and combined with dacarbazine chemotherapy. The benefit is observed in 10 to 20 % of the patients but it is the only drug to demonstrate an increase in overall survival of patients with metastatic melanoma. The pattern of response is new with delayed and prolonged responses over time. New evaluation criteria have been proposed to evaluate the efficacy of this new therapy. The safety profile is new also with frequent and potentially severe side effects related to the activation of the immune system. The challenges are now to identify biomarkers able to predict ipilimumab benefit and to know how to use ipilimumab in combination with new targeted therapies of melanoma in order to optimize the treatment efficacy.

Context-based speech recognition error detection and correction (2004)

In this paper we present preliminary results of a novel unsupervised approach for high-precision detection and correction of errors in the output of automatic speech recognition systems. We model the likely contexts of all words in an ASR system vocabulary by performing a lexical co-occurrence analysis using a large corpus of output from the speech system. We then identify regions in the data that contain likely contexts for a given query word. Finally, we detect words or sequences of words in the contextual regions that are unlikely to appear in the context and that are phonetically similar to the query word. Initial experiments indicate that this technique can produce high-precision targeted detection and correction of misrecognized query words.

Influence of Side-Chain Regiochemistry on the Transistor Performance of High-Mobility, All-Donor Polymers (2014)

Three novel polythiophene isomers are reported whereby the only difference in structure relates to the regiochemistry of the solubilizing side chains on the backbone. This is demonstrated to have a significant impact on the optoelectronic properties of the polymers and their propensity to aggregate in solution. These differences are rationalized on the basis of differences in backbone torsion. The polymer with the largest effective conjugation length is demonstrated to exhibit the highest field-effect mobility, with peak values up to 4.6 cm(2) V(-1) s(-1).
