Geometric Data Perturbation for Privacy Preserving in Data Stream Mining

Today as we have tendency to live within the era of information explosion. It’s become important to search for helpful data from large dataset. Additionally advance in web communication and hardware technology has lead to raise within the capability of storing personal information of people. Huge quantity of data stream are generated from completely different applications like shopping record, medical, network traffic etc. Sharing such type of information is incredibly important plus to business decision but the worry is that when the non-public information is leaked it may be abused for a different purposes. Therefore some quantity of privacy preserving must be done on the information before it is free to others. Ancient ways of Privacy Preserving Data Mining (PPDM) area unit designed for static information sets that makes its unsuitable for dynamic data streams. In this paper an economical and effective information perturbation methodology is proposed that aims to protect the privacy of sensitive attributes and obtaining information bunch with minimum information loss.
Long-Term Effects of Dredging Operations Program. Development of a Simplified Column Test for Evaluation of Thickness of Capping Material Required to Isolate Contaminated Dredged Material

Abstract : A procedure using a small-scale leaching column was developed for predicting the cap thickness required to chemically seal contaminated dredged sediment from the overlying water column. Several parameters, including dissolved oxygen depletion rates and release rates of ammonium-nitrogen, orthophosphate-phosphorus, and manganese, were evaluated as tracers for use in the predictive test. In addition, several tests were run using potassium chloride amendments to the contaminated sediment prior to capping to determine if this salt would be a suitable tracer. Dissolved oxygen depletion and ammoniumsion, orthophosphate-phosphorus release was also an effective tracer. Use of managanese or potassium chloride as tracers proved ineffective. Keywords: Dredged material, Leaching, Organic water pollutants, Tracers, contaminants.
The Curative Power of Play: The Voices of Therapists around the World

It is important for all therapists to be culturally sensitive to children and their eco-systems as well as to be aware of the current trends and the changing application of play as a healing agent. The focus of this study is on the development of a current description of play by therapists from a global perspective through a thematic analysis of focus groups resulting in an explanation of how play contributes to healing and the practice of therapy. In this study, the naturalistic method of qualitative research (Bowers, 2009; Lincoln & Guba, 1985) was applied to the study of play around the world, resulting in a new description of “play”. The analyses of focus group meetings in Morocco, Singapore, Hong Kong, Canada and Europe resulted in the emergence of 8 themes: productivity through play, contribution to development, facilitation of the relationship through play, honouring diversity, collaboration between children and caregivers, stimulation through technology-based play, relaxation provided by play, and the devaluation of play. These themes, which are presented through the “voices of the participants”, together with the literature review, serve to enrich the changing description of play. With participants from all continents, a current global perspective highlights the changes that play, both as a concept and as a healing agent, has undergone and will continue to do so. New information emerged suggesting that technology has become a worldwide focus for children but has a paradoxical effect on their relationships.
Measurements of Cumulonimbus Clouds using quantitative satellite and radar data

Results are reported for a preliminary study of SMS-2 digital brightness and IR data obtained at frequent 5-7.5 min intervals. The clouds studied were over the Central and Great Plains in midlatitudes and thus were typical of an environment much different from that of the tropical oceans. The satellite data are compared to radar data for both a severe weather event and weak thundershower activity of the type which might be a target for weather modification efforts. The relative importance of short time interval satellite data is shown for both cases, and possible relationships between the two types of data are presented. It is concluded that (1) using a threshold technique for visible reflected brightness, precipitating vs. nonprecipitating clouds can be discriminated; (2) brightness is well related to cloud size and shape; and (3) satellite-derived growth rates may be a significant parameter to be used in determining storm severity, especially if rapid time sequence data are used during the development phase of the storm.
Prognostic Utility of Neuraxis Imaging in Leptomeningeal Metastasis: A Retrospective Case Series

2037 Background: Correlate imaging of the central nervous system that includes both brain and spine MRI and radio-isotope cerebrospinal fluid [CSF] flow studies with survival in a retrospective case series of patients with LM. Methods: 240 adult patients with LM (125 non-brain solid tumor patients with positive CSF cytology; 40 non-brain solid tumor patients with negative CSF cytology and MRI consistent with LM; 50 lymphoma and 25 leukemia patients with positive CSF flow cytometry), all considered appropriate for LM-directed treatment, underwent prior to treatment brain and entire spine MRI and radio-isotope CSF flow studies. Results: Median overall survival was significantly shortened in patients with large volume MRI defined disease (defined as measurable tumor > 5 x 10 mm in orthogonal diameters) and in patients with non-corrected CSF flow obstruction irrespective of primary tumor histology. Additionally, cause of death differed wherein patients with large volume of disease or uncorrected obstructed CS.
Design, Synthesis and Molecular Docking Analysis of Flavonoid Derivatives as Potential Telomerase Inhibitors

Based on the structural scaffolds of natural products, two series of flavonoid derivatives, for a total of twelve compounds, were designed and synthesized as potential human telomerase inhibitors. Using a modified TRAP-PCR assay, compound 5c exhibited the most potent inhibitory activity against human telomerase with an IC50 value of less than 50 μM. In vitro, the results demonstrated that compound 5c had potent anticancer activity against five classes of tumor cell lines. The molecular docking and molecular dynamics analyses binding to the human telomerase holoenzyme were performed to elucidate the binding mode of active compound 5c. This finding helps the rational design of more potent telomerase inhibitors based on the structural scaffolds of natural products.
moGSA: integrative single sample gene-set analysis of 1 multiple omics data

14 Background : The increasing availability of multi-omics datasets has created an opportunity to 15 understand how different biological pathways and molecules interact to cause disease. However, there 16 is a lack of analysis methods that can integrate and interpret multiple experimental and molecular data 17 types measured over the same set of samples. 18 Result : To address this challenge, we introduce moGSA, a multivariate single sample gene-set analysis 19 method. It uses multivariate latent variable decomposition to discover correlated global variance 20 structure across datasets and calculates an integrated gene set enrichment score using the most 21 informative features in each data type. Integrating multiple diverse sources of data reduces the impact 22 of missing or unreliable information in any single data type, and may increase the power to discover 23 subtle changes in gene-sets. We show that integrative analysis with moGSA outperforms existing single 24 sample GSA methods on simulated data. We apply moGSA to two studies with real data. First, we 25 discover similarities and differences in mRNA, protein and phosphorylation profiles of induced 26 pluripotent and embryonic stem cell lines. Secondly, we report that three molecular subtypes are 27 robustly discovered when copy number variation and mRNA profiling data of 308 bladder cancers from 28 The Cancer Genome Atlas are integrated using moGSA. Our method provides positive or negative gene-29 set scores (with p-values) of each gene set in each sample. We demonstrate how to assess the influence 30 of each data type or gene to a moGSA gene set score. With moGSA, there is no requirement to filter 31 data to the intersect of features, therefore, all molecular features on all platforms may be included in 32 the analysis. 33 Conclusion : moGSA provides a powerful yet simple tool to perform integrated simple sample gene-set 34 analysis. Its latent variable approach is fundamentally different to existing single sample GSA 35 approaches. It is an attractive approach for data integration and is particularly suited to integrated 36 cluster or molecular subtype discovery. It is available in the Bioconductor R package “mogsa”.
Tail bounds for occupancy and the satisfiability threshold conjecture

The classical occupancy problem is concerned with studying the number of empty bins resulting from a random allocation of m balls to n bins. We provide a series of tail bounds on the distribution of the number of empty bins. These tail bounds should find application in randomized algorithms and probabilistic analysis. Our motivating application is the following well-known conjecture on threshold phenomenon for the satisfiability problem. Consider random 3-SAT formulas with cn clauses over n variables, where each clause is chosen uniformly and independently from the space of all clauses of size 3. It has been conjectured that there is a sharp threshold for satisfiability at c*/spl ap/4.2. We provide the first non-trivial upper bound on the value of c*, showing that for c>4.758 a random 3-SAT formula is unsatisfiable with high probability. This result is based on a structural property, possibly of independent interest, whose proof needs several applications of the occupancy tail bounds. <<ETX>>
SOME CHARACTERIZATIONS AND PROPERTIES OFTHE \ DISTANCE TO ILL-POSEDNESS " ANDTHE CONDITION MEASURE OF A CONIC LINEAR SYSTEM

A conic linear system is a system of the form P(d) : nd x that solves b ? Ax 2 C Y ; x 2 C X ; where C X and C Y are closed convex cones, and the data for the system is d = (A; b). This system is\well-posed" to the extent that (small) changes in the data (A; b) do not alter the status of the system (the system remains solvable or not). Renegar deened the \distance to ill-posedness," (d), to be the smallest change in the data d = ((A; b) for which the system P(d + d) is \ill-posed," i.e., d + d is in the intersection of the closure of feasible and infeasible instances d 0 = (A 0 ; b 0) of P(). Renegar also deened the \condition measure" of the data instance d as C(d) := kdk==(d), and showed that this measure is a natural extension of the familiar condition measure associated with systems of linear equations. This study presents two categories of results related to (d), the distance to ill-posedness, and C(d), the condition measure of d. The rst category of results involves the approximation of (d) as the optimal value of certain mathematical programs. We present ten diierent mathematical programs each of whose optimal values provides an approximation of (d) to within certain constants, depending on whether P(d) is feasible or not, and where the constants depend on properties of the cones and the norms used. The second category of results involves the existence of certain inscribed and intersecting balls involving the feasible region of P(d) or the feasible region of its alternative system, in the spirit of the ellipsoid algorithm. These results roughly state that the feasible region of P(d) (or its alternative system when P(d) is not feasible) will contain a ball of radius r that is itself no more than a distance R from the origin, where the ratio R=r satisses R=r = c 1 O(C(d)), and such that r = c 2 1 C(d) and R = c 3 O(C(d)), where c 1 ; c 2 ; c 3 are constants that depend only on properties of the cones and the norms used. Therefore the condition measure C(d) is a relevant tool in proving the existence of an inscribed ball in the feasible region of P(d) that is not too far from the origin and …
AIS Electronic Library (AISeL)

The advancement of mobile technology has transformed a phone from a simple communication tool to a powerful device for entertainment, socialization and work. The proliferation of mobile apps further changed people’s way of living and working. However, more and more users experience excessive mobile phone dependence. The traditional method to identify dependence uses survey instruments and interview. However, this approach is labour intensive and hard to scale. To address the issue, this research-in-progress paper aims to identity users’ phone usage pattern and propose an unobtrusive way of diagnosing users’ mobile phone dependence. We have developed an app to track users’ phone usage and preliminary analysis was performed based on the data collected over more than 20 days. Users showed different usage patterns over weekends and weekdays, and social app usage is a more significant indicator for mobile phone excessive dependence than general phone usage. Planned future analysis and potential contributions are discussed.
TYPES OF DEPTH OF CREEP IN SLOPES IN ROCK MASSES

DEPTH CREEP OF SLOPES IS A WIDE SPREADED PHENOMENON WHICH OCCURS NOT ONLY IN SOILS BUT IN ROCK MASSES AS WELL. DEFORMATION OF ROCK MASSES PROCEEDS EXTREMELY SLOWLY AND THE PROCESS IS OF SECULAR NATURE. DIFFERENT TYPES OF DEPTH CREEP ARE DISTINGUISHED DEPENDING ON THE GEOLOGICAL STRUCTURE AND RHEOLOGICAL CHARACTERISTICS OF ROCK STRATA. PLANAR DEPTH CREEP OCCURS ON LONG SLOPES WHEN THE STRATA DEPTH PARALLEL TO THE SLOPE AND ROCKS HAVE DIFFERENT RHEOLOGICAL CHARACTERISTICS. ROTATIONAL DEPTH CREEP OCCURS ON SHORT SLOPES WHEN THE SLOPE BODY CONSISTS OF HOMOGENEOUS ROCK MASSES. GENERAL DEPTH CREEP IS A COMMON TYPE OF SLOPE DEFORMATION WHICH OCCURS IN DIFFERENT GEOLOGICAL CONDITIONS. /AUTHOR/
Seasonal variation in SARS-CoV-2 transmission in temperate climates: A Bayesian modelling study in 143 European regions

Although seasonal variation has a known influence on the transmission of several respiratory viral infections, its role in SARS-CoV-2 transmission remains unclear. While there is a sizable and growing literature on environmental drivers of COVID-19 transmission, recent reviews have highlighted conflicting and inconclusive findings. This indeterminacy partly owes to the fact that seasonal variation relates to viral transmission by a complicated web of causal pathways, including many interacting biological and behavioural factors. Since analyses of specific factors cannot determine the aggregate strength of seasonal forcing, we sidestep the challenge of disentangling various possible causal paths in favor of a holistic approach. We model seasonality as a sinusoidal variation in transmission and infer a single Bayesian estimate of the overall seasonal effect. By extending two state-of-the-art models of non-pharmaceutical intervention (NPI) effects and their datasets covering 143 regions in temperate Europe, we are able to adjust our estimates for the role of both NPIs and mobility patterns in reducing transmission. We find strong seasonal patterns, consistent with a reduction in the time-varying reproduction number R(t) (the expected number of new infections generated by an infectious individual at time t) of 42.1% (95% CI: 24.7%—53.4%) from the peak of winter to the peak of summer. These results imply that the seasonality of SARS-CoV-2 transmission is comparable in magnitude to the most effective individual NPIs but less than the combined effect of multiple interventions.
Femtosecond Laser Written Plane-by-Plane Bragg Grating Sensors in Bioresorbable Phosphate Optical Fibres

We report on the realization of different types of optical sensors in a bioresorbable phosphate glass optical fiber using a femtosecond laser operating at 517 nm. We inscribed fiber Bragg grating-based optical filters such as uniform Bragg gratings, chirped gratings, and Fabry–Perot cavities, using the plane-by-plane direct write inscription. The gratings were characterized in reflection and tested as sensors for temperature and relative humidity. We studied the stability and resilience of the gratings when inserted in high humidity environments (>95%) for 52 h and observed the evolution of the grating characteristics during this period.
A possibility theory-based approach to the handling of uncertain relations between temporal points

Uncertain relations between temporal points are represented by means of possibility distributions over the three basic relations "smaller than", "equal to", and "greater than". Operations for computing inverse relations, for composing relations, for combining relations coming from different sources and pertaining to the same temporal points, or for representing negative information, are defined. An illustrative example of representing and reasoning with uncertain temporal relations is given. This paper shows how possibilistic temporal uncertainty can be handled in the setting of point algebra. Moreover, the paper emphasizes the advantages of the possibilistic approach over a probabilistic approach previously proposed. This work does for the temporal point algebra what the authors previously did for the temporal interval algebra.
A new Tutte polynomial for signed graphs

We construct a new polynomial invariant for signed graphs, the signed Tutte polynomial, which contains among its evaluations the number of proper colorings and the number of nowhere-zero flows. In this, it parallels the Tutte polynomial of a graph, which contains the chromatic polynomial and flow polynomial as specializations. The number of nowhere-zero tensions (for signed graphs they are not simply related to proper colorings as they are for graphs) is given in terms of evaluations of the signed Tutte polynomial at two distinct points. The signed Tutte polynomial is a special case of a trivariate polynomial invariant of ordered pairs of matroids - for a signed graph, the cycle matroid of its underlying graph and its signed-graphic matroid form the relevant pair of matroids - which is the canonically defined Tutte polynomial of ordered pairs of matroids in the sense of a recent paper of Krajewski, Moffatt and Tanasa. Furthermore, the Tutte polynomial of a matroid perspective as defined by Las Vergnas is contained as a specialization of this "joint Tutte polynomial" of matroid pairs.
Towards Sustainable Environmental Quality: Priority Research Questions for the Australasian Region of Oceania

Environmental challenges persist across the world, including the Australasian region of Oceania, where biodiversity hotspots and unique ecosystems such as the Great Barrier Reef are common. These systems are routinely affected by multiple stressors from anthropogenic activities, and increasingly influenced by global megatrends (e.g., the food–energy–water nexus, demographic transitions to cities) and climate change. Here we report priority research questions from the Global Horizon Scanning Project, which aimed to identify, prioritize, and advance environmental quality research needs from an Australasian perspective, within a global context. We employed a transparent and inclusive process of soliciting key questions from Australasian members of the Society of Environmental Toxicology and Chemistry. Following submission of 78 questions, 20 priority research questions were identified during an expert workshop in Nelson, New Zealand. These research questions covered a range of issues of global relevance, including research needed to more closely integrate ecotoxicology and ecology for the protection of ecosystems, increase flexibility for prioritizing chemical substances currently in commerce, understand the impacts of complex mixtures and multiple stressors, and define environmental quality and ecosystem integrity of temporary waters. Some questions have specific relevance to Australasia, particularly the uncertainties associated with using toxicity data from exotic species to protect unique indigenous species. Several related priority questions deal with the theme of how widely international ecotoxicological data and databases can be applied to regional ecosystems. Other timely questions, which focus on improving predictive chemistry and toxicology tools and techniques, will be important to answer several of the priority questions identified here. Another important question raised was how to protect local cultural and social values and maintain indigenous engagement during problem formulation and identification of ecosystem protection goals. Addressing these questions will be challenging, but doing so promises to advance environmental sustainability in Oceania and globally.
The Influence Of The Infusion Of Ephedrine And Phenylephrine On The Hemodynamic Stability After Subarachnoid Anesthesia In Senior Adults - A Controlled Randomized Study CURRENT STATUS:

ABSTRACT Study objective: We studied the influence of ephedrine or phenylephrine infusion given immediately after spinal anesthesia (SA) on hemodynamics in elderly orthopedic patients. Design: A prospective, randomized, double-blind, placebo-controlled study. Intervention: After subarachnoid injection of 15 mg of levobupivacaine the participants received either an infusion of ephedrine 20 mg (E group), phenylephrine 250 mcg (P group) or saline (C group) within 30 minutes. For 15 minutes before and and 30 minutes after SA we measured blood pressure, cardiac index (CI) and heart rate (HR). Results 70 patients were included in the final analysis. At the end of measurements mean arterial pressure decreased significantly after SA in comparison to baseline in the C group but was maintained in the P and the E group, with no significant differences between the groups. CI decreased after SA in the C group was maintained in the P group and increased significantly in the E group, with significant differences between the C and the E group (p=0.049) and between the P and the E (p=0.01) group at the end of measurements. HR decreased significantly after SA in the C and the P group and was maintained in the E group, with significant differences between the P and the E group (p=0.033) at the end of measurements. Conclusions Hemodynamic changes after SA in elderly orthopedic patients can be prevented by an immediate infusion of phenylephrine or ephedrine. In addition to maintaining blood pressure the ephedrine infusion also maintains HR and increases CI after spinal anaesthesia. return by adrenergic agonists during spinal anesthesia.
Intelligent Dispatching of Public Traffic Vehicles in ITS

In many applications, vehicular scheduling involves more complex criteria than that of travel time minimization. With regard to the actual status and operational environment of Public Traffic Vehicles (PTV), the optimal dispatching methods of PTV are dealt with by intelligent characteristics of Genetic Algorithm (GA). With one-point or two-point crossover of GA, various dispatching methods in three vehicular scales are confirmed. As an example from Beijing No.375 buses, the PTV dispatching results with GA are gained. The simulation results demonstrate that it is effective with GA to obtain good scheduling solutions by only searching the limited solution space. The method can be effectively used to improve the optimized results, and enhance operational efficiency, traveling safety and service level of PTV.
