Energy Aware Fuzzy Logic Secure Data Aggregation (EA-FSDA) technique for Wireless Sensor Networks

Increased demand for wireless communication system has gained huge attraction from various research communities, industries and academic field due to their significant advantages of facilitating efficient communication for real-time applications. With respect to wireless communication, monitoring (i.e. environmental) using WSN is considered as a significant task that has numerous challenging issues such as network deployment, data aggregation and data transmission in hazardous environmental conditions. In this work, we have focused on the data aggregation process in WSN and developed a novel approach to improve the network lifetime using a proposed solution based on the fuzzy logic scheme, which is called as Energy Aware Fuzzy Logic Secure Data Aggregation (EAFSDA). Furthermore, we present a privacy-aware mechanism for secure data aggregation to improve the system reliability. The privacy-preserving scheme is developed using homomorphic data encryption scheme. Hence, the proposed approach provides a complete solution for efficient and protected data aggregation for WSN that aids in improving the performance of the network. Finally, we present a comparative study which proves that the proposed EA-FSDA technique attains improved network performance in contrast with existing techniques.
Temperature Dependence of Growth and Fatty Acid Composition in the Cell Membrane of Mesophilic Bacteria Grown below the Optimum Growth Temperature

The features of Arrhenius plots of the relationship between specific growth rate and temperature for four strains of mesophilic bacteria varied depending on the cultivation temperature of the seed. An inflection point was observed around 20°C for the seed grown at 28 to 30°C but not for the seed grown previously at 15 to 17°C. The inflection temperature coincided with the phase transition temperature (around 23°C) determined by the DSC spectra of phospholipids extracted from the cells of Lactobacillus plantarum and Escherichia coil grown at 30°C. From the comparison of fatty acid compositions of phospholipids from the cells grown at different temperatures, unsaturated fatty acids were thought to be converted to corresponding cyclopropanoic acids by transmethylation at the higher temperature. Thus it was suggested that the increase in the cyclopropanoic acids causes the decrease in the membrane fluidity and the inflection point appears in the Arrhenius plot around 20°C for the seed grown at 28 to 30°C.
CUSTOMIZED MOBILE ADVERTISING WITHOUT PRIVACY CONCERNS BASED ON SIMILARITY ATTRACTION

This study explores the possibility of applying the sociopsychological phenomenon known as similarity attraction to the creation of more customized and persuasive mobile advertising, and for this purpose, we develop two applications, SensPlus and PerAds. While the SensPlus app accumulates the smartphone usage profiles of participants and constructs a regression model to predict their personality, the PerAds app presents user-created content according to the user’s personality. Using these two apps, we first design an advertising scheme providing a customized and persuasive advertising method without privacy concerns and then conduct an experiment to investigate the effectiveness of the smartphone ad scheme. The participants’ response to a smartphone ad is measured in terms of invitation acceptance of the cherry blossom festival and classical music concert. We analyze the rate of invitation acceptance using the χ 2 method. Our statistical analysis shows that participants respond differentially to the various types of smartphone ads according to the similarity between the personalities of the user and ad types. Our results indicate that the sociopsychological phenomenon can be introduced into practical application by replacing the personality trait factors with the smartphone usage pattern.
Interface between urban and rural: Determination of use status for Göktürk Forest Nursery

Istanbul, Turkey’s economic capital is in rapid change and development due to the increased population growth and spread. At this rapid change, the fringes become an important opportunity to establish the relationship between rural and urban and to meet the needs of people in terms of recreational requirements. The reserve areas, which are at the urban boundaries, such as 2-B lands 1 , forest nurseries, open mining areas and post-industrial sites have significant potential for re-use after losing their functions. Göktürk Forest Nursery was founded to meet the needs for production of forest trees and ornamental plants in 1969. Today it is in a transitional phase of urban development, changing into a place of interaction of both urban forms and rural landscape. Göktürk Forest Nursery should be appraised by using sustainable landscape planning and design processes to consider its physical, ecological, social and economic potential. This study examines the new use proposals for Göktürk Forestry Nursery at three scales; macro-scale analysis considering the 1/100.000 scale Istanbul Environmental Master Plan, medium-scale relation analysis considering Göktürk scale; and micro-scale analysis with Questionnaire method and a matrix of comparison between different urban green type scenarios for its future development.
Learning Dynamic Structure from Undersampled Data

Most causal learning algorithms for time series data assume that the underlying generative process operates on approximately the same timescale as the measurement process (or that any differences do not impede learning). This assumption fails in many domains, and so we ﬁrst show that undersampling creates learning challenges at the measurement timescale, even for simple generative processes. We then describe four algorithmic generalizations (some previously proposed, none previously tested)—two for continuous data, and two for either continuous or discrete data—and test them on simulated data. The results suggest that measurement timescale structure learning from undersampled time series data is feasible, but the appropriate model class needs to be used. Moreover, explicitly representing the possibility of undersampling can yield valuable regularization beneﬁts.
Transforming Growth Factor Beta 1 (TGFβ1) as an Immunological Marker in Breast Cancer Patients

Breast cancer is one of the most public and fatal malignancy worldwide. One of the main cytokines playing a role in breast cancer progression is TGF1. In this study we aimed to determine the clinical significance of the serum TGFβ1 levels in breast cancer patients by comparing the levels of TGFβ1 in breast cancer patients and in control females, assessment of the levels of TGFβ1 in diagnosed breast cancer patients before and after treatment and correlating between the levels of TGFβ1 in breast cancer patients with the laboratory and radiological findings. Our study was carried out on 35 breast cancer female cases and 20 females free from breast cancer with matched age as a control group. Higher levels of TGFβ1 are detected among breast cancer females than the control group with statistically significant difference between TGFβ1 after treatment as regarding to metastasis occurrence. This indicates that the circulating TGFβ1 after treatment may be used as a prognostic marker in breast cancer patients. Also, our study shows that there were statistically significant predictors affecting metastasis rate among studied cases when both ER was positive and TGFβ1 after treatment was more than median.

THE EFFECT OF STATOR WINDING PARAMETER DESIGN TO THE MAGNETIC FLUX CHARACTERISTICS IN HIGH-SPEED MOTOR APPLICATIONS

The purposed of this research is an evaluation of magnetic flux characteristics for the high-speed motors in different stator winding topologies. This is essentiality for developing a stator arrangement with lower stator leakage and higher magnetic flux linkage. The topologies of stator parameters are generated using Hooke-Jeeves optimization, Taguchi method, and response surface methodology (RSM). The influence of stator winding topologies obtained from design optimizations are evaluated by using flux linkage finite element analysis. The stator leakage and magnetic flux resulting from finite element are verified with prototype motor model produced by Taguchi method optimization. The result confirm that proposed designs reduce stator leakage reactance and increase magnetic flux linkage than initial design had. A comparing of the optimize design and the prototype experimental results confirm the reasonable of the suggested motor model.
Operator-Controlled Comparison Between 5 French and 6 French Guiding Catheters for Percutaneous Intervention Using Transradial Approach

Objective To compare 5 French (Fr) and 6 Fr guiding catheters regarding the volume of contrast administered, fluoroscopy time, and total procedure time during transradial percutaneous coronary intervention (PCI). Background Previous studies had compared 5 Fr and 6 Fr catheters and deemed 5 Fr catheters safe and effective. In this study, we retrospectively compared the 5 Fr catheter to 6 Fr catheter with an attempt to eliminate the effect of inter-operator skill level variability. Methods In a single-center, retrospective cohort study, we randomly selected patients who had received PCI through transradial access using 5 Fr or 6 Fr catheters. The study involved two groups of 100 patients each. These groups were comprised of an equal number of cases from each operator. The primary endpoint was contrast medium volume. Secondary endpoints were fluoroscopy time and procedure time. Results Less contrast was used in the 5 Fr group vs. 6 Fr catheter group (140.2 ± 45.7 mL vs. 158.2 ± 66.7 mL, p=0.004). PCI using 5 Fr catheters was associated with shorter fluoroscopy time (13.7 ± 7.3 mins vs. 15.2 ± 8.2 mins, p=0.584) and shorter procedure time (43.7 ± 22.2 mins vs. 46.5 ± 19.7 mins, p=0.890), but this was not statistically significant. Conclusion Transradial PCI using 5 Fr guiding catheters was associated with less contrast medium usage, but there was no advantage regarding procedure time or fluoroscopy time when compared to 6 Fr catheters. Similar to 6 Fr catheters, 5 Fr catheters achieved high PCI success rates through radial access when compared in the treatment of coronary lesions with the same level of complexity.
Biomechanical analysis of cross

CARRARA, P. D. S. Biomechanical analysis of cross on training and com petition rings. 2015. 77 p. Thesis (Doctoral in Sciences) School of Physical Education and Sport, University of São Paulo, São Paulo, 2015. The cross is a key element in Male Artistic Gymnast ics rings routines. The anatomical position during its execution requires 90° of shoul der abduction in frontal plane, which implies a large mechanical demand of shoulder joint s. For training condition, a modified rings apparatus is worldwide used to decrease shoulder lo ad and allow more repetitions of cross. Studies suggest that there is different shoulder mu scle activation between training and competition conditions. However, is not clear the t raining apparatuses specificity regarding biomechanics, considering kinematics, kinetics and electromyography in an individual basis. The aim of this thesis is to investigate the biomec hanics of the cross using training and competition rings devices. Twelve Brazilian elite g ymnasts were tested on isokinetic dynamometer for shoulder strength asymmetry and ele ctromyography assessment. Within one week interval, participants performed in their trai ning place, three crosses in rings and in training apparatus randomly. One digital video came ra, one strain gauge in each cable and surface electromyography of nine shoulder muscles w re used. Statistical analyses were performed by parametric and non-parametric tests an d descriptive statistics. Shoulder strength asymmetry RMS values were 9.9±6.4%. The asymmetry o f sh ulder strength and cross performance on rings had an individual basis relati on. Shoulder angles on training device had less deviation from target 90° of abduction on trai ning apparatus than on rings and smaller asymmetry value. Cable forces had similar values in both apparatuses, as the asymmetry values. Electromyography of nine muscles and co con traction values differences were not different between the types of rings. The training ri s allowed the gymnasts to better perform the cross without changing shoulder muscle activati on patterns. An individual orientation for gymnasts to perform the cross on training apparatus within the same way they perform in competition rings, it is necessary for the maintena nce of equivalent biomechanical characteristics.
Dispersal and association of two alien species in the Indonesian coral reefs: the octocoral Carijoa riisei and the demosponge Desmapsamma anchorata

The discovery of the association between the sponge Desmapsamma anchorata (Demospongiae: Poecilosclerida: Desmacididae) and the octocoral Carijoa riisei (Cnidaria: Alcyonacea: Clavularidae) on an Indonesian reef enlarges the widespread dispersion of these Atlantic species in the Indo-Pacific area. The species involved and their morphological adaptations resulting from the association are described. When covered by the sponge, C. riisei develops an irregular branching pattern and a dense nematocyst layer where the ectoderm comes in contact with the sponge tissue. The finding of fertile colonies suggests that the Indonesian population of C. riisei is self-sustaining.
Defenses of Caribbean sponges against invertebrate predators. I. Assays with hermit crabs

Hermit crabs (Decapoda: Anomura) are typically omnivorous and are common on Caribbean coral reefs. Sponges are sessile, fleshy, and high in protein and energy content, yet hermit crabs do not appear to prey on them. Assays were performed with the Caribbean reef hermit crab Paguristes punticeps to determine whether secondary metabolites or skeletal elements of Caribbean sponges that were incorporated into artificial foods affected feeding. Of 30 sponge species assayed, 26 (87 %) yielded organic extracts that deterred feedlng by P punticeps. There was substantial interspecific and intraspecific vanabllity in patterns of chemical deterrence. Sponges of the families Axinellidae, Agelasidae, Aplysinidae, Aplysinellidae, and Thorectidae typically yielded deterrent extracts. Three common sponge species, Mycale laevis, Callyspongla vaginalis, and Niphates erecta, were consistently non-deterrent, while other species, including Spheciospongja othella, Chondrilla nucula, Callyspongia plicifera. Niphates digitalis, and Xestospongia muta, were variably deterrent. These results are in general agreement with those of a previous survey of Caribbean sponge chemical defenses using the common reef fish Thalassoma bifasciatum. However, some results differed: Geodia neptuni and Iotrochota birotulata were consistently palatable to T. bifasciatum, but were deterrent to P. punticeps. Several species that were consistently deterrent to 7 bifasciatum were variably deterrent to P punticeps, including Aplysina caulifornus, Aplysina fulva, Ircinia strobilina, Amphimedon compressa, and Mycale laxjssima. Neither spicules (from Agelas clathrodes, Ectyoplasia feros, and Xestospongia muta) nor splculated spongin skeleton (from A. clathrodes and X. muta) deterred feeding by P, punticeps. Spicules and spiculated spongin were similarly non-deterrent to the fish T bifasciatum in a previous survey. The results of this study further suggest that chemical defenses are important in the ecology of Caribbean sponges, while skeletal components do not serve an antipredatory function.
The snails the dinosaurs saw: are the pleurocerid populations of the Older Appalachians a relict of the Paleozoic Era?

Abstract Pleurocerid snails are a common element of the benthos in rivers and streams throughout the Appalachian highlands from Virginia to Georgia on both sides of the continental divide. Yet their dispersal capabilities are so limited today that significant gene frequency differences have been demonstrated over a scale of meters. We obtained mitochondrial cytochrome oxidase c subunit I (COI) sequence data from 3 individual snails sampled from each of 13 populations of pleurocerids representing 3 species—Leptoxis carinata (4 populations), Goniobasis (“Elimia”) catenaria (4 populations), and Goniobasis (“Elimia”) proxima (5 populations). To these data we added previously published COI sequences from 3 other G. proxima populations. Levels of intrapopulation sequence divergence were strikingly high, ranging up to 21.9% within populations and 22.6% between populations within species. A neighbor-joining analysis revealed 3 loose clusters corresponding to the species, but featured numerous extreme outliers. Wilcoxon rank-sum tests returned no evidence that the Continental Divide (as it presently stands) makes any contribution to mean levels of interpopulation sequence divergence, nor that simple geographic distance (regardless of modern drainage) has an effect. We suggest that populations of pleurocerid snails inhabiting the Older Appalachians might date to such an age that all geographic signal in the divergence of our test gene has been lost. We review additional lines of evidence from other genetic studies and from ecology, life history, continental biogeography, and the fossil record that suggest that our pleurocerid populations might be living fossils from the Paleozoic uplift of the Appalachians.
Chemical Characterization, Temperature Stability, and Enzymatic Studies on Edible Marine Algae Kappaphycus alvarezii (Doty)

Antioxidant activity of the marine alga Kappaphycus alvarezii was investigated. Methanol, acetone, petroleum ether, aqueous methanol, ethyl acetate, and chloroform extracts (1 mg/mL) of K. alvarezii were tested for their 2, 2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activity. The values were compared with those of Vitamin C and butylated hydroxytoluene (BHT). Extracts showing positive results, when tested for DPPH free radical scavenging, were examined for dose effect, in-vivo hydrogen peroxide (H2O2) and hydroxyl radical scavenging assays. All extracts showed dose-dependent DPPH scavenging and significant hydroxyl radical scavenging activities (> 82.6%). The acetone, aqueous methanol, and methanol extracts of K. alvarezii showed the highest scavenging activity. Ethyl acetate extract showed a moderate activity of 62.9%. In the DPPH method, petroleum ether and hexane extracts showed less activity with IC50 values of 118.58 ± 8.94 and 116.25 ± 7.14 μg/mL, respectively. Acetone, methanol, and ethyl acetate extracts exhibited IC50 values of 57.32 ± 1.07, 61.31 ± 0.67, and 79.50 ± 1.59 μg/mL, respectively. K. alvarezii showed higher antioxidant activity in both in vitro and in vivo studies. Proton NMR studies revealed signals in the region 0.5 to 2.0 ppm suggesting the presence of steroidal identity in the extracts.
Structure-function relationships and energy transfer in phycobiliprotein antennae

The present understanding of how interactions between chromophore and protein as well as between chromophore and chromophore in different aggregation states influence the spectral and excited state kinetic properties of phycobiliprotein antenna pigments is discussed. Properties of isolated phycobiliproteins from both cyanobacteria and red algae as well as from cryptophytes and of intact phycobilisomes are covered. The experimental results are discussed in terms of general principles for chromophore coupling and energy transfer. Some controversial topics in this field are outlined.
AR-DAE: Towards Unbiased Neural Entropy Gradient Estimation

Entropy is ubiquitous in machine learning, but it is in general intractable to compute the entropy of the distribution of an arbitrary continuous random variable. In this paper, we propose the amortized residual denoising autoencoder (AR-DAE) to approximate the gradient of the log density function, which can be used to estimate the gradient of entropy. Amortization allows us to significantly reduce the error of the gradient approximator by approaching asymptotic optimality of a regular DAE, in which case the estimation is in theory unbiased. We conduct theoretical and experimental analyses on the approximation error of the proposed method, as well as extensive studies on heuristics to ensure its robustness. Finally, using the proposed gradient approximator to estimate the gradient of entropy, we demonstrate state-of-the-art performance on density estimation with variational autoencoders and continuous control with soft actor-critic.
Semilinear elliptic equations involving mixed local and nonlocal operators

In this paper, we consider an elliptic operator obtained as the superposition of a classical second-order differential operator and a nonlocal operator of fractional type. Though the methods that we develop are quite general, for concreteness we focus on the case in which the operator takes the form − Δ + ( − Δ)s, with s ∈ (0, 1). We focus here on symmetry properties of the solutions and we prove a radial symmetry result, based on the moving plane method, and a one-dimensional symmetry result, related to a classical conjecture by G.W. Gibbons.
Applications of higher-dimensional Heegaard Floer homology to contact topology

The goal of this paper is to set up the general framework of higher-dimensional Heegaard Floer homology, define the contact class, and use it to give an obstruction to the Liouville fillability of a contact manifold and a sufficient condition for the Weinstein conjecture to hold. We discuss several classes of examples including those coming from analyzing a close cousin of symplectic Khovanov homology and the analog of the Plamenevskaya invariant of transverse links.
Reconstruction of Potassium Concentrations with the ECG on Imbalanced Datasets

End-stage chronic kidney disease (CKD) patients are facing a 30% rise for the risk of lethal cardiac events (LCE) compared to non-CKD patients. At the same time, these patients undergoing dialysis experience shifts in the potassium concentrations. The increased risk of LCE paired with the concentration changes suggest a connection between LCE and concentration disbalances. To prove this link, a continuous monitoring device for the ionic concentrations, e.g. the ECG, is needed. In this work, we want to answer if an optimised signal processing chain can improve the result quantify the influence of a disbalanced training dataset on the final estimation result. The study was performed on a dataset consisting of 12-lead ECGs recorded during dialysis sessions of 32 patients. We selected three features to find a mapping from ECG features to [K+]o: T-wave ascending slope, T-wave descending slope and T-wave amplitude. A polynomial model of 3rd order was used to reconstruct the concentrations from these features. We solved a regularised weighted least squares problem with a weighting matrix dependent on the frequency of each concentration in the dataset (frequent concentration weighted less). By doing so, we tried to generate a model being suitable for the whole range of the concentrations.With weighting, errors are increasing for the whole dataset. For the data partition with [K+]o<5 mmol/l, errors are increasing, for [K+]o$\geq$5 mmol/l, errors are decreasing. However, and apart from the exact reconstruction results, we can conclude that a model being valid for all patients and not only the majority, needs to be learned with a more homogeneous dataset. This can be achieved by leaving out data points or by weighting the errors during the model fitting. With increasing weighting, we increase the performance on the part of the [K+]o that are less frequent which was desired in our case.
