Fusion of data from sources with different levels of trust

In the context of this paper, trust is defined to be “a measure of to what degree an information source is believed to be capable of producing information that conforms to fact. ” No standard method has been adopted by the intelligence community for fusing data from sources with different levels of trust. This paper proposes an approach that extends the standard application of Bayesian inference to allow for the fact that any piece of intelligence data may be less than fully trustworthy. Based on a prototypical intelligence scenario from which synthetic data was generated, results indicate that trust models produce results which are closer to the ground truth than those for a model containing no trust variables, exhibit less variability and which provide a better basis for making correct decisions.
Cancerous Cell Detection UsingHistopathological Image Analysis

Histopathology refers to the examination of biopsy samples by a pathologist using a microscope for analysing and classifying diseases. In order to study the manifestations of a disease, the analysis of histopathological image is done manually by a pathologist and therefore the diagnosis is subjective and greatly dependent on the level of expertise of the professional. In order to overcome this problem of a possible erroneous diagnosis and for early stage detection, an automated computerized image processing system is needed for quantitative diagnosis of biopsy samples. In this paper we have proposed a model for early stage cancerous cell detection and have reviewed and summarized the phases involved, namely, Image Pre-processing, Image Segmentation, Feature Extraction and Classification.
Implementation of K-Nearest Neighbor with Cosine Similarity for Classification Abstract International Journal of Computer Science

The spread of international journals or scientific articles as research supporting material is increasing. This makes the number of available journal documents make it more difficult to find and present journals. Text processing techniques are needed that can categorize large amounts of text documents according to their type, the information available can be accessed properly and easily accessed according to user needs. One of the problems solving in categorizing text documents can be solved by using a text mining method that is classification. This research uses the K-Nearest Neighbor classification algorithm with cosine similarity to categorize the maximum journal document. In general, this research conducted four stages. The initial stage is a process of preprocessing data consisting of case folding, character removal, tokenizing and stopwords removal. The second stage performs TF-IDF weighting on each term and splits a dataset of 450 journals for data sharing training and data testing. The splitting method used is the data holdout method and ten-fold cross-validation. The third stage is modeling the classification using cosine similarity, and K-Nearest Neighbor with the value of k used is 3,6,7,9. There are three abstract categories including Computer and Education, Computer and Security and Computer in Human Behavior. The last stage of analyzing the results of the classification performed. The result shows 10 fold cross validation method can give better result at k = 9 with precision value 80,18% recall 51,11% and f1-measure 62,42%.
Suicidal Ideation Among National Guard Troops Deployed to Iraq: The Association With Postdeployment Readjustment Problems

Abstract Despite well-documented postdeployment readjustment problems affecting veterans of Operations Enduring Freedom (OEF) and Iraqi Freedom (OIF), few studies have explored the possible relationship of readjustment stressors to the recent increase in military suicide. This study examined associations between suicidal ideation and postdeployment readjustment problems using cross-sectional population-based survey data from 1665 National Guard members who recently returned from Iraq. The findings suggested that readjustment problems are widespread, with 45% of veterans endorsing one or more financial or family problems 3 months postdeployment. After adjusting for mental health and combat exposure, veterans with the highest number of readjustment stressors were at 5½ times greater risk of suicidal ideation than those with no stressors. In a psychiatrically impaired subsample, the high stressor group experienced a fourfold risk of suicide ideation compared with those with no stressors. The findings argue for suicide prevention efforts that more directly target readjustment problems in returning OEF/OIF veterans.
Improved Bounds for Geometric Permutations

We show that the number of geometric permutations of an arbitrary collection of $n$ pair wise disjoint convex sets in $\mathbb{R}^d$, for $d\geq 3$, is $O(n^{2d-3}\log n)$, improving Wenger's 20 years old bound of $O(n^{2d-2})$.
Inborn Errors of Metabolism

We estimated the sensitivity of a screening procedure (SP) for inborn errors of metabolism (IEM) in 566 referred, high-risk patients. The 143 (25.3% of the total sample) patients with initial abnormal results in at least one screening test (ST) were recalled for further investigations. An IEM was diagnosed in 40.6 percent of the 106 patients who came for reevaluation. In 114 of the remaining 423 patients who had normal initial ST, an IEM was still suspected on basis of clinical, radiological, and/or laboratory findings and was confirmed in 30 of such patients (5.3% of the total sample and 7.1% of the patients with normal results in the SP). The sensitivity of the SP was estimated maximally as 67.4 percent and the efficiency as 80.4 percent. Twenty-five of the 30 cases undetected with the SP were patients with sphingolipidoses. The simple inclusion of thin-layer chromatography of urinary oligosaccharides in the SP should allow the detection of at least one half of these cases, increasing its sensitivity by 14.1 percent and its efficiency by 4.6 percent. In at least 7.1 percent of patients with an initial normal ST, an IEM was detected. These would have remained undiagnosed if the limitations of the SP employed had not been fully understood.
AMREF: An Adaptive MapReduce Framework for Real Time Applications

This paper presents AMREF, an Adaptive Map Reduce Framework designed for an effective use of computational resources in data center networks to deal with real time data intensive applications. AMREF entails its adaptivity from adaptive splitter, adaptive mappers and adaptive reducers in a stochastic control manner. We use three methods, feedback control, stochastic learning with smooth filter and kalman filter to implement the framwork. Comparison among the three methods suggests they can be effectively and efficiently used to reduce the makspan in three different real-world workload scenarios.
Validation of the Greek Cypriot Translation of the Triarchic Psychopathy Measure

ABSTRACT Psychopathy is conceived of as a pathological constellation of personality traits, manifested in aberrant behavioral, interpersonal, and emotional tendencies. This study examined within a Greek-speaking nonclinical sample (N = 419) associations between differing phenotypic dimensions of psychopathy (boldness, meanness, disinhibition) assessed via the Triarchic Psychopathy Measure (TriPM) and self-report criterion measures of psychopathology, personality, and history of abuse and neglect. Consistent with predictions of the triarchic model of psychopathy, evidence was found for distinct correlates of the 3 phenotypic dimensions. Boldness was associated with both adaptive (immunity to anxiety/distress, fearlessness, low hostility) and maladaptive tendencies (grandiose manipulative traits, Machiavellian features including desire for control/status, and verbal aggression). Meanness was related to callous and unemotional traits, features of Machiavellianism (e.g., amoral manipulation and distrust of others), physical aggression, and absence of positive parenting. Disinhibition, by contrast, was characterized by anxiety and distress, exposure to violence, and retrospective accounts of abuse history, along with impulsive, irresponsible, and hostile tendencies. These findings indicate that the Greek-Cypriot translation of the TriPM effectively assesses the constructs of the triarchic model and extend what we know about their empirical correlates.
Seismic visualization of plumes and super-deep fluids in mantle under Ukraine

According to the Taylor approximation of the three-dimensional P-velocity model of the mantle under Eurasia, a seismic visualization of the manifestation of mantle plumes and super-deep fluid processes was carried out. As initial data, the times of the first arrival of the P-wave were used according to the ISC bulletins for the period 1964—2006. The research area is defined in the interval (45—50° N)Ч(23—48° E) to the depth of 2500 km, in the interval (51—55° N)Ч(23—48° E) to the depth of 1700 km according to the used observation system and includes a mantle near Sarmatia (including the territory of Ukraine) and its surroundings. The fluid domain is defined as the region of the yields of low-velocity heterogeneities from the lower, middle mantle to the upper one and spreading along the laterals of their central part. The central, low-velocity part of the fluid domain is defined as a plume. Hence, the fluid domain is an area associated with traces of the passage of plumes. The mantle under the territory of Ukraine is under the influence of the North-Azov, Volyn-Orsha and Central-Black Sea fluid domains and regions of their spreading. The upper mantle above the central part of the North-Azov fluid domain (to a depth of 525 km) and above the central part of the Volyn-Orsha fluid domain (to a depth of 300 km) is high-velocity one. In the case under consideration, taking into account the absence of manifestations of the outlet of the central region of the fluid domain from the lower mantle and the presence of a high-velocity upper mantle, it can be expected that both of these central regions associated with the manifestation of plumes are in the decay stage. The central regions of both the North-Azov and Volyn-Orsha fluid domains belong to the areas of articulation of tectonic structures. The North Azov fluid domain is confined to the junction of the Khoper megablock of the Voronezh Massif and the Donbas, the Volyn-Orsha to the Kursk megablock of the Voronezh Massif, the Orsha Depression (Volyn-Orsha aulakogen) and the north-western part of the Dneprovo-Donets Basin. In the area of spreading of both the North-Azov and Volyn-Orsha fluid domains, 12 super-deep fluids are emitted.
Analysis of Faculty Perceptions toward Blended Learning Adoption at Higher Education Institutes in Oman

is study is mainly intended to identify the factors affecting blended learning adoption, and to find out whether the teaching process is predictive in its adoption at HEIs in Oman. The study adopted quantitative approach that aimed to examine the effect of teaching styles on blended learning adoption. The findings revealed that teaching styles, significantly mediated the relationship of User Acceptance of Technology (UAT) and Blended Learning adoption. Blended learning in the theoretical framework may improve the interaction in learning environment and support effective learning, through greater flexibility. This research is an extension to the study conducted erstwhile on evaluating the perceptions of "Students" towards blended learning adoption at HEIs in Oman (4).
Genetic KCa3.1-Deficiency Produces Locomotor Hyperactivity and Alterations in Cerebral Monoamine Levels

Background The calmodulin/calcium-activated K+ channel KCa3.1 is expressed in red and white blood cells, epithelia and endothelia, and possibly central and peripheral neurons. However, our knowledge about its contribution to neurological functions and behavior is incomplete. Here, we investigated whether genetic deficiency or pharmacological activation of KCa3.1 change behavior and cerebral monoamine levels in mice. Methodology/Principal Findings In the open field test, KCa3.1-deficiency increased horizontal activity, as KCa3.1−/− mice travelled longer distances (≈145% of KCa3.1+/+) and at higher speed (≈1.5-fold of KCa3.1+/+). Working memory in the Y-maze was reduced by KCa3.1-deficiency. Motor coordination on the rotarod and neuromuscular functions were unchanged. In KCa3.1−/− mice, HPLC analysis revealed that turn-over rates of serotonin were reduced in frontal cortex, striatum and brain stem, while noradrenalin turn-over rates were increased in the frontal cortex. Dopamine turn-over rates were unaltered. Plasma catecholamine and corticosterone levels were unaltered. Intraperitoneal injections of 10 mg/kg of the KCa3.1/KCa2-activator SKA-31 reduced rearing and turning behavior in KCa3.1+/+ but not in KCa3.1−/− mice, while 30 mg/kg SKA-31 caused strong sedation in 50% of the animals of either genotypes. KCa3.1−/− mice were hyperactive (≈+60%) in their home cage and SKA-31-administration reduced nocturnal physical activity in KCa3.1+/+ but not in KCa3.1−/− mice. Conclusions/Significance KCa3.1-deficiency causes locomotor hyperactivity and altered monoamine levels in selected brain regions, suggesting a so far unknown functional link of KCa3.1 channels to behavior and monoaminergic neurotransmission in mice. The tranquilizing effects of low-dose SKA-31 raise the possibility to use KCa3.1/KCa2 channels as novel pharmacological targets for the treatment of neuropsychiatric hyperactivity disorders.
Selection of AUG initiation codons differs in plants and animals.

The influence of the nucleotide at position ‐3 relative to the AUG initiation codon on the initiation of protein synthesis was studied in two different in vitro translation systems using synthetic mRNAs. The four mRNAs, transcribed from cDNAs directed by an SP6 promoter, were identical except for mutations at nucleotide ‐3. In each case, translation of mRNAs produced a single protein of Mr = 12,600. Relative translational efficiencies showed a hierarchy in the reticulocyte lysate system (100, 85, 61 and 38% for A, G, U and C in position ‐3, respectively) but no differences in the wheat germ system. Differential mRNA degradation or polypeptide chain elongation were excluded as causes of the differences observed in translation in the reticulocyte lysate. mRNA competition increased the differences observed in translational efficiencies in reticulocyte lysate but showed no effect in wheat germ. Analysis of 61 plant and 209 animal mRNA sequences revealed qualitative and quantitative differences between the consensus sequences surrounding AUG initiation codons. Whereas the consensus sequence for animals was CACCAUG that for plants was AACAAUGGC. Both the structural and functional findings suggest that the factors which select AUG initiation codons in plants and animals differ significantly.
In Situ Permeability and Scale Dependence of an Active Accretionary Prism Determined From Cross‐Borehole Experiments

Permeability controls fluid flow in the Earth's crust and affects a wide range of processes including advective transport and pore pressure generation. However, in situ measurements of permeability are few, especially in active tectonic settings or at scales relevant to regional flow. We analyze formation fluid pressure records from oceanic boreholes in the Nankai accretionary prism offshore southwest Japan, focusing on unexpected responses to drilling operations conducted at boreholes ~100 m to the northeast. We develop a 2‐D numerical model of transient fluid flow and conduct a parametric grid search to define hydraulic diffusivity. A value of 0.19–0.46 m2/s (corresponding to a permeability of 9.8 × 10−13 to 2.4 × 10−12 m2) yields the best fit to observed pressure responses. Together with laboratory measurements on core samples and drillstrem tests reported in previous studies, our analysis indicates a strong scale dependence of permeability, likely reflecting the presence of permeable faults and fractures.
A High-Temperature Solar Selective Absorber Based upon Periodic Shallow Microstructures Coated by Multi-Layers Using Atomic Layer Deposition

Regarding the fabrication of solar selective absorbers, the ability to create microstructures on top of metal surfaces is a promising technology. Typically, these materials are able to possess spectrally-selective absorption properties for high-temperature usage. Solar-selective absorbers that function at temperatures up to 700 °C and possess shallow honeycomb cylindrical microcavities coated with a metal-dielectric multi-layer have been investigated. Honeycomb array cylindrical microcavities were fabricated on W substrate with interference lithography and multi-layers consisting of Pt nano-film sandwiched by Al2O3 layers were created for a uniform coating via atomic layer deposition. The absorbance spectrum of fabricated samples reveals results consistent with a simulation based on a rigorous coupled-wave analysis method. A solar absorbance value of 0.92 and a hemispherical total emittance value of 0.18 at 700 °C was determined from the fabricated solar-selective absorber. Additionally, thermal stability of up to 700 °C was confirmed in vacuum.
Dechlorination of Bleached Kraft Pulp by Laccase Enzyme Produced from Some White-Rot Fungi

The possibility of using crude laccase in the dechlorination of chlorine-based bleached kraft pulp was investigated. Culture supernatants of seven white-rot fungal strains and kraft-pulp samples taken from E1 (Alkaline Extraction-1), E2 (Alkaline Extraction-2) and D2 (Chlorinedioxide treatment) stages of chlorine-based bleaching processes were used as the laccase source and substrates respectively during the studies. The dechlorination activity of Trametes versicolor was found to be more than that of the other fungi examined. The addition of a laccase inducer, xylidine, into the culture medium of T. Versicolor led to an increase in dechlorination activity. In the experiment performed to find out the role of laccase activity in dechlorination reactions, a considerable reduction in the dissolved oxygen concentration due to laccase-dependent dechlorination activity was observed. Stepwise enzyme treatment was found to be necessary for increasing the yield of dechlorination.
Hardness of Approximation for Strip Packing

Strip packing is a classical packing problem, where the goal is to pack a set of rectangular objects into a strip of a given width, while minimizing the total height of the packing. The problem has multiple applications, for example, in scheduling and stock-cutting, and has been studied extensively. When the dimensions of the objects are allowed to be exponential in the total input size, it is known that the problem cannot be approximated within a factor better than 3/2, unless P= NP. However, there was no corresponding lower bound for polynomially bounded input data. In fact, Nadiradze and Wiese [SODA 2016] have recently proposed a (1.4 + ε)-approximation algorithm for this variant, thus showing that strip packing with polynomially bounded data can be approximated better than when exponentially large values are allowed in the input. Their result has subsequently been improved to a (4/3 + ε)-approximation by two independent research groups [FSTTCS 2016, WALCOM 2017]. This raises a question whether strip packing with polynomially bounded input data admits a quasi-polynomial time approximation scheme, as is the case for related two-dimensional packing problems like maximum independent set of rectangles or two-dimensional knapsack. In this article, we answer this question in negative by proving that it is NP-hard to approximate strip packing within a factor better than 12/11, even when restricted to polynomially bounded input data. In particular, this shows that the strip packing problem admits no quasi-polynomial time approximation scheme, unless NP} ⊑ DTIME(2polylog (n)).
DVB-C2 - The standard for next generation digital cable transmission

Cable network operators provide a variety of different services, which include analogue and digital TV, Video on Demand (VoD) and also Internet access. The increasing number of these broadband services will require higher bit-rates that are not achievable in many of today's cable networks. The development of DVB-C2 has been finalized recently, providing a cost effective opportunity to upgrade these networks. The new standard utilizes powerful LDPC codes and QAM constellation sizes up to 4096QAM. Additionally, it is based on OFDM instead of single-carrier modulation, which gives additional flexibility and robustness in typical cable channels. This document will give an introduction to the algorithms and the performance of this new DVB-C2 standard.
Automated anatomical labeling of the bronchial branch and its application to the virtual bronchoscopy system

This paper describes a method for the automated anatomical labeling of the bronchial branch extracted from a three-dimensional (3-D) chest X-ray CT image and its application to a virtual bronchoscopy system (VBS). Automated anatomical labeling is necessary for implementing an advanced computer-aided diagnosis system of 3-D medical images. This method performs the anatomical labeling of the bronchial branch using the knowledge base of the bronchial branch name. The knowledge base holds information on the bronchial branch as a set of rules for its anatomical labeling. A bronchus region is automatically extracted from a given 3-D CT image. A tree structure representing the essential structure of the extracted bronchus is recognized from the bronchus region. Anatomical labeling is performed by comparing this tree structure of the bronchus with the knowledge base. As an application, the authors implemented the function to automatically present the anatomical names of the branches that are shown in the currently rendered image in real time on the VBS. The result showed that the method could segment about 57% of the branches from CT images and extracted a tree structure of about 91% in branches in the segmented bronchus. The anatomical labeling method could assign the correct branch name to about 93% of the branches in the extracted tree structure. Anatomical names were appropriately displayed in the endoscopic view.
N′-Cyclopentylidenepyridine-4-carbohydrazide

The title compound, C11H13N3O, is a derivative of the antituberculosis drug isoniazid [systematic name: pyridine-4-carbohydrazide]. The crystal structure consists of repeating hydrogen-bonded chains parallel to the b axis. Adjacent molecules in the chains are linked by bifurcated N—H⋯(O,N) hydrogen bonds, which form an R 1 2(5) ring motif.
Identification of Pleonastic It Using the Web

In a significant minority of cases, certain pronouns, especially the pronoun it, can be used without referring to any specific entity. This phenomenon of pleonastic pronoun usage poses serious problems for systems aiming at even a shallow understanding of natural language texts. In this paper, a novel approach is proposed to identify such uses of it : the extrapositional cases are identified using a series of queries against the web, and the cleft cases are identified using a simple set of syntactic rules. The system is evaluated with four sets of news articles containing 679 extrapositional cases as well as 78 cleft constructs. The identification results are comparable to those obtained by human efforts.
