Context-based exploitation of data warehouses

An OLAP analysis can be defined as an interactive session during which an user launches queries over a data warehouse. The launched queries are often interdependent, and they can be either newly defined queries or they can be existing ones that are browsed and reused. Moreover, in a collaborative environment, queries may be shared among users. This notion of OLAP analysis has never been formally defined. In this paper, we propose a clear definition of this notion, by introducing a model for sharing, browsing and reusing OLAP queries over a data warehouse.
Ionic currents and charge movements in organ‐cultured rat skeletal muscle.

The middle of the fibre voltage‐clamp technique was used to measure ionic currents and non‐linear charge movements in intact, organ‐cultured (in vitro denervated) mammalian fast‐twitch (rat extensor digitorum longus) muscle fibres. Muscle fibres organ cultured for 4 days can be used as electrophysiological and morphological models for muscles in vivo denervated for the same length of time. Sodium currents in organ‐cultured muscle fibres are similar to innervated fibres except that in the temperature range 0‐20 degrees C (a) in the steady state, the voltage distribution of inactivation in cultured fibres is shifted negatively some 20 mV; (b) at the same temperature and membrane potential, the time constant of inactivation in cultured fibres is about twice that of innervated fibres. Potassium currents in innervated and cultured fibres at 15 degrees C can be fitted with the Hodgkin‐Huxley n variable raised to the second power. Despite the large range we would estimate that the maximum value of the steady‐state potassium conductance of cultured fibres is about one‐half that of innervated fibres. The estimated maximum amount of charge moved in cultured fibre is about one‐third that in innervated fibres. Compared to innervated fibres, culturing doubles the kinetics of the decay phase of charge movement. The possibility of a negative shift of the voltage distribution of charge movements in cultured fibres is discussed.
Receptor for Activated C-Kinase 1 Regulates the Cell Surface Expression and Function of ATP Binding Cassette G2

In a previous report, we identified the receptor for activated C-kinase 1 (RACK1) as a positive regulator of the cellular localization and expression of ATP-binding cassette B4, a phosphatidylcholine translocator expressed on the bile canalicular membrane. In the present study, we focused on the role of RACK1 on ATP-binding cassette G2 (ABCG2), which is responsible for the cellular extrusion of compounds including antitumor drugs. Protein expression of ABCG2 was up-regulated by RACK1 overexpression, although mRNA expression of ABCG2 was not dependent on RACK1. The effect of RACK1 on the expression of ABCG2 on the cell surface was confirmed by the uptake of [3H]estrone sulfate, an ABCG2 substrate, into isolated membrane vesicles. The expression of RACK1 affected cellular resistance to mitoxantrone, an anticancer drug excreted by ABCG2, and this effect of RACK1 was abolished in the presence of fumitremorgin C, a selective ABCG2 inhibitor. These results suggest that RACK1 has functional significance as a regulatory cofactor of ABCG2 and is indispensable for the cell surface expression and excretion function of ABCG2. The precise mechanism for RACK1-dependent expression of ABCG2 remains to be clarified, because the results of N-benzoyloxycarbonyl (Z)-Leu-Leu-leucinal (MG132) and chloroquine treatment and those of metabolic labeling experiments did not give us clear evidence whether the reduction of ABCG2 expression in RACK1-knocked down cells may be caused by the suppression of ABCG2 protein synthesis or by acceleration of its degradation.
Continuous spectrum sensing and transmission in MIMO cognitive radio network

Data transmission of secondary users in classical cognitive radio networks is not allowed within the sensed band during the sensing period resulting in underutilization of the available spectrum. Aiming at a higher network throughput than in classical approaches, the spectrum sensing is performed at the receiving node of the secondary network instead of the transmitting node. This allows the transmitter to use the available band until notified by the network of the presence of a primary user. In this paper, we extend this concept to a MIMO spectrum sensing with arbitrary numbers of primary and secondary transmitters as well as of sensors of the secondary receiver. Our contributions are the theoretical approximations in Section III that help to compute the detection and false alarm probabilities valid only for a large number of samples of gaussian signals using energy detection technique. Large quantity of samples is needed to compensate interference of secondary signals in the sensing process. The proposed theoretical model is validated via various Monte Carlo numerical performance evaluations assuming Rayleigh fading communication channels.
Heteroclinic travelling waves for the lattice sine-Gordon equation with linear pair interaction

The existence of travelling heteroclinic waves for the sine-Gordon lattice is proved for a linear interaction of neighbouring atoms. The asymptotic states are chosen such that the action functional is finite. The proof relies on a suitable concentration-compactness argument, which can be shown to hold even though the associated functional has no sub-additive structure.

Syntheses of 1,2,3-triazole-bridged pyranose sugars with purine and pyrimidine nucleobases and evaluation of their anticancer potential

ABSTRACT With the aim to create a library of compounds with potential bioactivities by combining special characteristics of two important groups such as nucleobases and carbohydrates, twenty 1,4-disubstituted-triazole nucleosides were synthesized in good yields (80-94%) using the copper catalyzed ‘Click’ reaction between azido-modified pento- or hexopyranoses and alkyne-bearing pyrimidine or purine nucleobases. Structural elucidation was made with the assistance of spectroscopic techniques such as FTIR, 1D-, 2D-NMR, and ESI-TOFMS. All the synthesized triazole nucleosides were evaluated for their cytotoxic activity against three human cancer cell lines (MDA-MB-231, Hep3B, PC-3) by using the MTT assay. Particularly, compounds 3a and 1b were identified as potential hits against Hep3B cell.
On interacting control loops in self-adaptive systems

Control loops in self-adaptive systems are typically conceived as a sequence of four computations: Monitor-Analyze-Plan-Execute (MAPE). During the development of a traffic monitoring system with support for self-healing, we have noticed that simple MAPE loops are not sufficient to deal with the more complex failure scenarios. To manage the adaptations in these scenarios, we extend MAPE loops with support for two types of coordination. First, we introduce support for intra-loop coordination enabling MAPE computations within one loop to coordinate with one another. Intra-loop coordination allows the execution of multiple sub-loops within one control loop. Second, we introduce support for inter-loop coordination enabling MAPE computations across multiple loops to coordinate with one another. Inter-loop coordination allows the MAPE computations of different loops to coordinate the various phases of adaptations. We show how we used the extensions to support self-healing in the traffic monitoring system. We discuss an implementation framework that supports coordination of MAPE loops, and from our experiences offer recommendations for future research in this area.
Visual Category Learning Results in Rapid Changes in Brain Activation Reflecting Sensitivity to the Category Relation between Perceived Objects and to Decision Correctness

Little is known about the time scales in which sensitivity to novel category identity may become evident in visual and executive cortices in visual category learning (VCL) tasks and the nature of such changes in brain activation. We used fMRI to investigate the processing of category information and trial-by-trial feedback information. In each VCL task, stimuli differed in three feature dimensions. In each trial, either two same-category stimuli or two different-categories stimuli were presented. The participant had to learn which feature dimension was relevant for categorization based on the feedback that followed each categorization decision. We contrasted between same-category stimuli trials and different-category trials and between correct and incorrect categorization decision trials. In each trial, brain activation in the visual stimuli processing phase was modeled separately from activation during the later feedback processing phase. We found activation in the lateral occipital complex, indicating sensitivity to the category relation between stimuli, to be evident in VCL within only few learning trials. Specifically, greater lateral occipital complex activation was evident when same-category stimuli were presented than when different-category stimuli were presented. In the feedback processing phase, greater activation in both executive and visual cortices was evident primarily after “misdetections” of same-category stimuli. Implications regarding the contribution of different learning trials to VCL, and the respective role of key brain regions, at the onset of VCL, are discussed.
American National standard for writing abstracts

An abstract is defined as an abbreviated, accurate representation of a document which should be published with it and which is also useful in secondary publications and services. Make the abstract as informative as the nature of the document will permit, so that readers can decide, quickly and accurately, whether they need to read the entire document. State the purpose, either in that order or with initial emphasis on findings (results and conclusions). Make each abstract self-contained since it must be intelligible without reference to the document itself.
On the Analysis of Groupware Usability Using Annotated GOMS

GOMS is a well-known model that has been successfully used in predicting the performance of human-computer interaction, identifying usability problems and improving user-interface design. The focus of GOMS is on the individual user, however. This explains why it has no significant impact in the groupware context. This paper discusses the applicability of GOMS in the groupware context. We analyzed the impact of groupware in the cognitive architecture of GOMS in order to
A 0.35µm 1.25V piezo-resistance digital ROIC for liquid dispensing MEMS

A CMOS digital ROIC is presented for multi-channel and differential piezo-resistive sensing, as part of the positioning system of a liquid dispensing MEMS. New very low-voltage and single-battery compatible circuit techniques are proposed for digital gain tuning, pre-amplification and A/D conversion. Also, overall low-power consumption is achieved by operating key devices in subthreshold to prevent from heating the fluidic MEMS. The complete system has been integrated in 0.35 mum CMOS 2-polySi 4-metal technology.
Ratio of cross sections for double to single ionization of He by 85-400 eV photons.

The ratio of double to single ionization of He by 85{endash}400 eV photons has been measured using cold target recoil ion momentum spectroscopy. This technique allows the elimination of all possible systematic errors discussed so far in the literature on this subject. We find the ratio in this energy range to be about 25{percent} lower than previously assumed. {copyright} {ital 1996 The American Physical Society. }
Analyzing cooperative coevolution with evolutionary game theory

The task of understanding coevolutionary algorithms is very difficult. These algorithms search landscapes which are, in some sense, adaptive. As a result, the dynamical behaviors of coevolutionary systems can frequently be even more complex than traditional evolutionary algorithms (EAs). Moreover, traditional EA theory tells us little about coevolutionary algorithms. One major question that has yet to be clearly addressed is whether or not coevolutionary algorithms re well-suited for optimization tasks. Although this question is equally applicable to competitive, as well as cooperative approaches, answering the question for cooperative coevolutionary algorithms is perhaps more attainable. Recently, evolutionary game theoretic (EGT) models have begun to be used to help analyze the dynamical behaviors of coevolutionary algorithms. One type of EGT model which is already reasonably well understood are multi-population symmetric games. We believe these games can be used to analytically model cooperative coevolutionary algorithms. This paper introduces our analysis framework, explaining how and why such models may be generated. It includes some examples illustrating specific theoretical and empirical analyses. We demonstrate that using our framework, a better understanding for the degree to which cooperative coevolutionary algorithms can be used for optimization can be achieved.
Antitumor Effect of Nanoparticle 131I-Labeled Arginine-Glycine-Aspartate-Bovine Serum Albumin-Polycaprolactone in Lung Cancer.

OBJECTIVE The aim of the present study is to investigate the biologic effects of internal irradiation and the therapeutic effectiveness of 131I-labeled arginine-glycine-aspartate (RGD)-bovine serum albumin (BSA)-polycaprolactone (PCL) (131I-RGD-BSA-PCL) in murine lung cancer models. MATERIALS AND METHODS The target binding and cellular uptake of NCI-H460 lung cancer cells overexpressing integrin αvβ3 were observed by confocal microscopy. Flow cytometry was used to assay apoptosis. The biologic effects of internal irradiation and the therapeutic efficacy of 131I-RGD-BSA-PCL were investigated in murine lung cancer models; tumor size, body weight, histopathologic findings, and SPECT/CT imaging findings were also monitored. RESULTS In vitro uptake studies performed using confocal microscopy showed that, after 1 hour of incubation with RGD-BSA-PCL or BSA-PCL, visible fluorescence was present in the cells, and after 8 hours, the florescent signal did not disappear. The mean (± SE) tumor uptake level (i.e., the percentage of the injected dose per gram of tissue [% ID/g]) of 131I-labeled BSA-PCL (131I-BSA-PCL) at 24 and 72 hours after injection was 11.06% ± 2.15% ID/g and 3.83% ± 0.87% ID/g, respectively, which is significantly higher than the uptake levels noted for other organs (p < 0.05). The level of tumor uptake of 131I-RGD-BSA-PCL at 24 and 72 hours after injection was 39.49% ± 6.06% ID/g and 6.97% ± 1.43% ID/g, respectively, which is significantly higher than that of 131I-labeled liposome (p < 0.05). The decrease in body weight in the group treated with 131I-RGD-BSA-PCL was only 3.5% of the original body weight and was much lower than noted in the group receiving saline (i.e., 21.5% of original body weight). The median survival time for the therapeutic groups was prolonged to 27 days and 23 days after treatment with 131I-RGD-BSA-PCL and 131I-BSA-PCL, respectively. CONCLUSION RGD-BSA-PCL has excellent cellular binding in vitro in a non-small cell lung cancer xenograft model. Furthermore, 131I-RGD-BSA-PCL was evaluated as an imaging agent and is an interesting candidate for targeting therapies in the non-small cell lung cancer xenograft model.
Joint estimation of crown of thorns (Acanthaster planci) densities on the Great Barrier Reef

Crown-of-thorns starfish (CoTS; Acanthaster spp.) are an outbreaking pest among many Indo-Pacific coral reefs that cause substantial ecological and economic damage. Despite ongoing CoTS research, there remain critical gaps in observing CoTS populations and accurately estimating their numbers, greatly limiting understanding of the causes and sources of CoTS outbreaks. Here we address two of these gaps by (1) estimating the detectability of adult CoTS on typical underwater visual count (UVC) surveys using covariates and (2) inter-calibrating multiple data sources to estimate CoTS densities within the Cairns sector of the Great Barrier Reef (GBR). We find that, on average, CoTS detectability is high at 0.82 [0.77, 0.87] (median highest posterior density (HPD) and [95% uncertainty intervals]), with CoTS disc width having the greatest influence on detection. Integrating this information with coincident surveys from alternative sampling programs, we estimate CoTS densities in the Cairns sector of the GBR averaged 44 [41, 48] adults per hectare in 2014.
End binding protein‐1 (EB1) complements microtubule‐associated protein‐1B during axonogenesis

The different strains of microtubule‐associated protein (MAP)‐1B‐deficient mice that have been generated appear to express different phenotypes. This variability could be the consequence of the distinct genetic backgrounds of the animals used to generate these lines. Certain proteins might be able to complement the deficit of MAP1B function in these mice. Therefore, we examined whether the concentrations of potential compensatory proteins varied among these mutant strains. In this way, we identified significant differences in the amounts of the microtubule‐associated EB1 protein between two of these strains. Furthermore, in transfection studies, we demonstrated that the overexpression of end binding protein‐1 (EB1) could facilitate axonogenesis in MAP1B–/– cells in which EB1 is normally weakly expressed. Thus, we suggest that EB1 could complement MAP1B function during neural development. © 2005 Wiley‐Liss, Inc.
Study on characteristics of rural settlements in the northeast loess plateau of china by RS&GIS

Based on the field investigation and analysis of RS data of rural settlements in the study area during the 23 years from 1979 to 2002, we reached the following main conclusions. First, the type of landscape structure in the study area is simple and the main landscape type is cropland (87.52%, 2002). Second, the distribution characteristics are mainly relevant to the situation of landform, water system, traffic and market town in the study area. Third, we not only clarified changes of land-use scale in rural settlement, but also studied rural settlement system by using the scale and grade model of rural settlement system (SGMRS). Fourth, we expounded the characteristic of rural settlement expansion in scale, speed and types between 1979 and 2002, disclosed the gravity of rapid expansion of the rural settlement, and pointed out some difficult problems brought about by it. Fifth, we collected the information of space change of rural settlements, such as direction, speed and process of settlement expansion through remote sensing images. The main factors affecting expansion of rural settlements are even topography, population growth, family scale change, family income growth, transportation improvement, industrialization and the alteration of land-use policy in rural areas after 1979.
The effects of stress on blood sugar composition of the lobster, Homarus americanus.

Freshly caught intermolt lobsters show a highly significant elevation of blood glucose after a few minutes of mild stress. Females show a significantly greater increase than males. The small amounts of other sugars in the blood are great enough to explain the increase in glucose, and chromatographic analysis shows that they diminish under stress. In postmolt animals the stress hyperglycaemia is not as great but is still significant; the difference between the sexes is not apparent. Lobsters held in commercial pounds were found to be in a hyperglycaemic condition. The stress of commercial handling and prolonged fasting brings about significant changes in blood sugars and the sexes react differently. The rather better survival of females under these conditions may also be significant.
Measurement Techniques for Online Battery State of Health Estimation in Vehicle-to-Grid Applications

The evolution of the power grid calls for a smarter infrastructure, capable of integrating different energy sources and all the different kind of users of the grid. In addition, it should be able to dynamically adapt to fluctuations in loads and sources. In the Smart Grid scenario, energy storage systems (ESSs) play a fundamental role, allowing for decoupling production and usage times. Lithium ion batteries are among the most promising technologies in ESSs. They will allow for a full exploitation of renewable energy sources, can be used to shape load curves and constitute the energy reserve in battery electric vehicles. In addition, if such vehicles are plugged into the power grid, they can act as support electricity storage, realizing the so-called vehicle-to-grid (V2G) paradigm. In all these applications, the reliability of the battery system must be guaranteed. Therefore, measurement techniques to assess the state of health of batteries are needed. In this paper, with particular reference to V2G applications, two fast techniques to compute an index representing the state of health of a Li-ion battery are introduced. The first one relies on fuzzy logic, while the second is based on a neural network. In both cases, an early characterization of batteries in the same family of the ones to be monitored is needed. Compared with experimental data, the techniques exhibit good performances without the need for great processing power. Their performances are adequate for the intended V2G fleet management purpose.
