Kurtosis: A Critical Review

We critically review the development of the concept of kurtosis. We conclude that it is best to define kurtosis vaguely as the location- and scale-free movement of probability mass from the shoulders of a distribution into its center and tails and to recognize that it can be formalized in many ways. These formalizations are best expressed in terms of location- and scale-free partial orderings on distributions and the measures that preserve them. The role of scale-matching techniques and placement of shoulders in the formalizations that have appeared in the literature are emphasized.
An End-to-End Multi-task Learning Model for Fact Checking

With huge amount of information generated every day on the web, fact checking is an important and challenging task which can help people identify the authenticity of most claims as well as providing evidences selected from knowledge source like Wikipedia. Here we decompose this problem into two parts: an entity linking task (retrieving relative Wikipedia pages) and recognizing textual entailment between the claim and selected pages. In this paper, we present an end-to-end multi-task learning with bi-direction attention (EMBA) model to classify the claim as “supports”, “refutes” or “not enough info” with respect to the pages retrieved and detect sentences as evidence at the same time. We conduct experiments on the FEVER (Fact Extraction and VERification) paper test dataset and shared task test dataset, a new public dataset for verification against textual sources. Experimental results show that our method achieves comparable performance compared with the baseline system.
Quaderni di ricerca del Dipartimento di Scienze Economiche “ Hyman P . Minsky ” Anno 2005 n . 4 Crime and Labour Market Opportunities in Italy ( 1993-2002 )

This paper investigates the relationship between labour market conditions and crime in Italy accounting for both age and gender in unemployment measure and considering regional disparities between North-Centre and South of Italy. Using regional data over the period 1993-2002, we study the impact of wages and unemployment on different types of crime. To mitigate omitted-variables bias we control extensively for demographic and socioeconomic variables. Empirical results suggest that unemployment has a large and positive effect on crime rate in southern regions. Our results are robust to model specification, endogeneity, changes in the classification of crimes and finally, to alternative definitions of

A Neuro-Fuzzy Based System for the Classification of Cells as Cancerous or Non-Cancerous

Objectives: In this study, we developed a neuro-fuzzy based system for classification of cancerous and non-cancerous lung cells. Methods: Images were pre-processed using median filter algorithm, segmented using marker-controlled watershed algorithm, and were extracted using gray-level co-occurrence matrix. A hybridized diagnosis system that made use of neural network and fuzzy logic for classification of lung cells into cancerous and non-cancerous cells is modelled. Computed tomography (CT) scan image dataset of the lung was downloaded from The Cancer Imaging Archive dataset. Neural network performed the training and classification of the lung cells with back-propagation algorithm, while the cancerous cells were passed into fuzzy inference system to determine the lung cancer stage. Results: Our system was able to successfully classify the imported CT scan images into normal or abnormal with considerably high accuracy of 70% and precision of 89%. This system can support physicians in decision making when diagnosing cancer.

All viruses are obligatory parasites that must develop tight interactions with their hosts to complete their infectious cycle. Viruses infecting plants share many structural and functional similarities with those infecting other organisms, particularly animals and fungi. Quantitative data regarding their evolutionary mechanisms – generation of variability by mutation and recombination, changes in populations by selection and genetic drifthave been obtained only recently, and appear rather similar to those measured for animal viruses. This review presents an update of our knowledge of the phylogenetic and evolutionary characteristics of plants viruses and their relation to their plant hosts, in comparison with viruses infecting other organisms.

Adsorption Properties of Copper (II) Ion From Aqueous Solution by Starch-Grafted Polyacrylamide and Crosslinked Starch-Grafted Polyacrylamide

Starch-grafted polyacrylamide (SA) and cross-linked starch-grafted polyacrylamide (CSA) had been synthesized via grafting polymerization from corn starch and used as adsorbents for the removal of Cu(II) ion from aqueous solution. The equilibrium, kinetics and thermodynamics of adsorption processes of SA and CSA were investigated and compared. It was found that the adsorption capacity of Cu(II) of SA and CSA could reach the maximum within 60 min when the pH was 6. The adsorption kinetics of CSA and SA for Cu(II) was favorably described by the pseudo-second-order kinetic model and the adsorption isotherm was described well with the Freundlich isotherm model. Thermodynamic studies indicated that the adsorption was a spontaneous and endothermic process with increased entropy, and the rise of temperature would benefit the adsorption; the enthalpy change(ΔH), the entropy change (ΔS) and free energy change (ΔG) of the adsorption process of Cu(II) on SA and CSA were calculated with adsorption isotherm data and basic thermodynamic relations.
Opportunities and Challenges in Realizing the Full Potential of SiC Power Devices

E volutionary improvements in silicon (Si) power devices through better device designs, processing techniques, and material quality have led to great advancements in power systems in the last four decades. However, many commercial power devices are now approaching the theoretical performance limits offered by the Si material in terms of the capability to block high voltage, provide low on-state voltage drop, and switch at a high frequency. Therefore, in the past five to six years, many power system designers have been looking for alternative solutions in order to realize advanced commercial and military hardware that requires higher power density circuits and modules. One of the most promising approaches is to replace Si as the material of choice for fabrication of power devices with a wider bandgap

The persistence of synthetic pesticides in the environment has caused considerable changes in legislation regarding the use of them. This, coupled with the consumer trend for natural alternatives has brought increasing attention to the application of plant derivatives (essential oils, plant extracts and components) as environmentally sustainable pesticides against microorganisms, insects and nematodes. Furthermore, natural products can be found in developing countries where medicinal and aromatic plants grow in abundance. The unique and complex structure of essential oils makes it difficult for pests to develop resistance to them. Additionally, the volatile nature of the essential oil components due to their low molecular weights makes them less likely to persist in the soil.
Authorship Verification: A Review of Recent Advances

Authorship verification attempts to decide whether the author of a given set of texts is also the author of a disputed text. In comparison to closed-set and open-set attribution, the most popular tasks in relevant literature, the verification setting has some important advantages. First, it is more general since any attribution problem can be decomposed into a series of verification cases. Then, certain factors that affect the performance of closed-set and open-set attribution, like the candidate set size and the distribution of training texts over the candidate authors have limited impact on authorship verification. It is, therefore, more feasible to estimate the error rate of authorship attribution technology, needed in the framework of forensic applications, when focusing on the verification setting. Recently, there has been increasing interest for authorship verification, mainly due to the PAN shared tasks organized in 2013, 2014, and 2015. Multiple methods were developed and tested in new benchmark corpora covering several languages and genres. This paper presents a review of recent advances in this field focusing on the evaluation results of PAN shared tasks. Moreover, it discusses successes, failures, and open issues.
Exsudação de ácido cítrico e teor de alumínio em diferentes regiões de raízes de milho (Zea mays L.).

1-INTRODUÇÃO O conhecimento dos mecanismos de tolerância ao Al apresentados pelas plantas é fundamental para produção de cultivares tolerantes a este elemento. Contudo, as bases fisiológicas destes mecanismos não estão totalmente compreendidas (Kochian et al., 2004). Não existe ainda consenso sobre o sítio primário da ação tóxica do alumínio na célula, porém, sabe-se que o ápice radicular é o ponto chave no processo da ação tóxica do metal. Acredita-se que o alumínio provoque danos celulares, por sua influência negativa na parede celular, na membrana plasmática, no transporte de íons ou na tradução de sinais iniciados na membrana (Ma et al., 2001). Ácidos orgânicos exercem um importante papel na detoxificação interna e externa do Al, pois possuem grupos carboxílicos que se ligam ao Al, no simplasto ou no apoplasto (quando exsudados), reduzindo sua toxidez (Ryan et al., 2001). A exsudação de ácidos orgânicos por células de ápice de raiz, provocada pelo contato específico do Al com estas células, diminui a atividade dos íons de Al livres, pela formação de quelatos, reduzindo o contato destes íons com a parede celular e com a membrana plasmática (Ryan et al., 2001; Barceló et al., 1996). Em raízes de milho foi observada exsudação de ácidos orgânicos ativada pelo Al, sendo o citrato o principal ânion orgânico exsudado (Pellet et al., 1995). Experimentos realizados até o momento tem detectado a presença destes ácidos em solução nutritiva, impossibilitando a localização da exsudação na raiz. O objetivo deste trabalho foi quantificar a exsudação de ácido cítrico em regiões da raiz, de três linhagens de milho com tolerância diferencial ao Al; verificar a contribuição de outras partes radiculares na exsudação de ácido cítrico, a relação entre a tolerância apresentada pelas plantas e sua exsudação, e a correlação entre a quantidade de ácidos exsudada com o teor de alumínio detectado na raiz.
Biomarkers of Vitamin B 6 Status Per

Measures of B6 status are categorized as direct biomarkers and as functional biomarkers. Direct biomarkers measure B6 vitamers in plasma/serum, urine and erythrocytes, and among these plasma pyridoxal 5�-phosphate (PLP) is most commonly used. Functional biomarkers include erythrocyte transam­ inase activities and, more recently, plasma levels of metabolites involved in PLP-dependent reactions, such as the kynurenine pathway, one-carbon metabolism, transsulfuration (cystathionine), and glycine decarboxylation (serine and glycine). Vitamin B6 status is best assessed by using a combina­ tion of biomarkers because of the influence of potential confounders, such as inflammation, alkaline phosphatase activity, low serum albumin, renal func­ tion, and inorganic phosphate. Ratios between substrate-products pairs have recently been investigated as a strategy to attenuate such influence. These efforts have provided promising new markers such as the PAr index, the 3­ hydroxykynurenine:xanthurenic acid ratio, and the oxoglutarate:glutamate ratio. Targeted metabolic profiling or untargeted metabolomics based on mass spectrometry allow the simultaneous quantification of a large number of metabolites, which are currently evaluated as functional biomarkers, using data reduction statistics.
Lattice Boltzmann Modeling of Thermal Conduction in Composites with Thermal Contact Resistance

© Global-Science Press 2015. The effective thermal conductivity of composite materials with thermal contact resistance at interfaces is studied by lattice Boltzmann modeling in this work. We modified the non-dimensional partial bounce-back scheme, proposed by Han et al. [Int. J. Thermal Sci., 2008. 47: 1276-1283], to introduce a real thermal contact resistance at interfaces into the thermal lattice Boltzmann framework by re-deriving the redistribution function of heat at the phase interfaces for a corrected dimensional formulation. The modified scheme was validated in several cases with good agreement between the simulation results and the corresponding theoretical solutions. Furthermore, we predicted the effective thermal conductivities of composite materials using this method where the contact thermal resistance was not negligible, and revealed the effects of particle volume fraction, thermal contact resistance and particle size. The results in this study may provide a useful support for materials design and structure optimization.
Macdonald Polynomials of Type Cn with One-Column Diagrams and Deformed Catalan Numbers

We present an explicit formula for the transition matrix $\mathcal{C}$ from the type $C_n$ Macdonald polynomials $P^{(C_n)}_{(1^r)}(x|b;q,t)$ with one column diagrams, to the type $C_n$ monomial symmetric polynomials $m_{(1^{r})}(x)$. The entries of the matrix $\mathcal{C}$ enjoy a set of certain three term recursion relations, which can be regarded as a $(b,q,t)$-deformation of the one for the Catalan triangle or ballot numbers. It is also shown that the $q$-ballot numbers appear as the Kostka polynomials, namely in the transition matrix from the Schur polynomials $P^{(C_n)}_{(1^r)}(x|q;q,q)$ to the Hall-Littlewood polynomials $P^{(C_n)}_{(1^r)}(x|t;0,t)$.
The Influence of Morphology Upon Two-Temperature Statements for Convective Transport in Porous Media

Transport models for forced, single phase fluid convection are reviewed for non-uniformly and randomly structured highly porous media. Special attention is given to the evaluation of a twotemperature energy model. For means of comparison, a one-temperature, effective thermal diffusivity model is developed, emphasizing local solid phase morphology using analytic techniques. Random characteristics of the porous medium are simulated by the use of regular and unspecified, pre-assigned solid phase morphologies. An overall coefficient of drag resistance is determined by implementing a multiple-regime superposition approach. Coefficient models are evaluated using the governing averaged transport equations set and solved numerically. Variability of the morphology descriptors is shown to potentially govern large fluctuations in transport parameter values and distributions. Results generally compare favorably among work by Koch and Brady; Fand and Thinakaran; Adnani, Raffray, Abdou, and Catton; and Watanabe.
Antiproliferative Activity and Apoptosis Induction by Gelam Honey on Liver Cancer Cell Line

Gelam honey is a Malaysian monofloral honey produced by Apis mellifera from Melaluca spp. It has high polyphenols content that possesses antioxidant and free radical scavenging activity towards preventing cancer and diseases. This study was to determine the antiproliferative effects of gelam honey on liver cancer, HepG2. MTS assay was carried to obtain IC50 value of gelam honey towards HepG2 and normal liver, WRL-68 cell lines. The cells proliferation rates were determined by BrdU assay and morphological cell changes were detected by using propidium iodide staining. The IC50 value of gelam honey towards HepG2 and WRL-68 cells was 25% and 70% respectively. Gelam honey reduced the proliferation of HepG2 at concentrations of 3% to 70%. Morphological analysis for apoptosis detection using fluorescent microscope under 400X magnification producing typical apoptotic characteristic. It showed that gelam honey has antiproliferative activity towards cancer cell by its ability to induce apoptosis.
Advances in Radio Science Countermeasures against NBTI degradation on 6 T-SRAM cells

In current process technologies, NBTI (negative bias temperature instability) has the most severe aging effect on static random access memory (SRAM) cells. This degradation effect causes loss of stability. In this paper countermeasures against this hazard are presented and quantified via simulations in 90 nm process technologies by the established metrics SNMread, SNMhold, Iread and Write Level. With regard to simulation results and practicability best candidates are chosen and, dependent on individual preferences at memory cell design, the best countermeasure in each case is recommended.
Event Processing in Code Generation and Execution Framework of UML State Machines

While generating code not only from UML class diagrams but also from state machines, we have to cope with inconsist encies and semantic variation points of the UML specification. The Fram ework for eXecutable UML (FXU) transforms UML models into programming code and supports execution of the resulting application according to the behavioral model. The FXU is the first framework supporting all elements of UML 2.x state machines in code generation and execution for C# code. In th is paper we focus on the event processing and determination of transition pr iorities resolved within the framework. Two selected problems of not-distinct ev ent priorities occurring in orthogonal states together with proposed solutions are also presented.
Drawing of single-crystal and glass-clad lithium tantalate fibers by the laser-heated pedestal growth method

Lithium tantalate (LT) single-crystalline fibers with various growth conditions were obtained using the laser-heated pedestal growth (LHPG) method. The fibers can be produced with a diameter down to 70 µm and tens of centimetres in length by using different pulling rates. Preliminary experiments also showed that the LT fibers can be electrically poled for quasi-phase matching. To facilitate wave propagation with low loss, glass-clad LT fibers were fabricated by a co-drawing LHPG method for the first time. A vacuum apparatus was developed to eliminate the bubbles from incongruent evaporation of lithium oxide during the drawing of the glass-clad LT fibers. The glass-clad fibers are classified into two different categories by the measurements of refractive index profiles. One is a step-index fiber and the other is a graded-index fiber. Both fiber types are multimode at present, but single-mode LT fibers could be fabricated with the high-precision control of the LHPG systems.
Stochastic Geometry Modeling for Uplink Cellular V2X Communication

To overcome the limitations of Dedicated Short Range Communications (DSRC) with short range, nonsupportability of high density networks, unreliable broadcast services, signal congestion and connectivity disruptions, vehicleto-everything (V2X) communication networks, standardized in 3rd Generation Partnership Project (3GPP) Release 14, have been recently introduced to cover broader vehicular communication scenarios including vehicle-to-vehicle (V2V), vehicle-topedestrian (V2P) and vehicle-to-infrastructure/network (V2I/N). Motivated by the stringent connection reliability and coverage requirements in V2X , this paper presents the first comprehensive and tractable analytical framework for the uplink performance of cellular V2X networks, where the vehicles can deliver their information via V2N/cellular network (vehicle-to-base station, V2B communication link) or directly between vehicles in the sidelink, based on their distances, propagation environments and the bias factor. By practically modeling the vehicles on the roads using the doubly stochastic Cox process and the BSs, we derive new association probabilities of V2B and V2V links, new success probabilities of the V2B and V2V communications, and overall success probability of the V2X communication, which are validated by the simulations results. Our results reveal the benefits of V2X communication compared to V2V communication in terms of success probability.
