Neural network model based on anti-error data fusion

Trend of error of the measured data is found by using wavelet transform, and the reliability of the measured data is tested according to the error trend, and the weights of the measured data are determined. Then anti-error data fusion method is proposed. After the data fusion, a model for three-phase cable fault system is constructed by choosing BP neural network with an improved BP algorithm, and the prediction and location of cable fault can be implemented based on neural network model. Simulation shows that the outputs of neural network model are nearly close to the outputs of the practical system, and the mean value of errors of cable fault distance predicted by the neural network model that is constructed by using the anti-error data is quite less than that by using the data before fusion. So the anti-error data fusion method is correct and the NN model of cable fault system is reliable.
A Hybrid of the Chemical Master Equation and the Gillespie Algorithm for Efficient Stochastic Simulations of Sub-Networks

Modeling stochastic behavior of chemical reaction networks is an important endeavor in many aspects of chemistry and systems biology. The chemical master equation (CME) and the Gillespie algorithm (GA) are the two most fundamental approaches to such modeling; however, each of them has its own limitations: the GA may require long computing times, while the CME may demand unrealistic memory storage capacity. We propose a method that combines the CME and the GA that allows one to simulate stochastically a part of a reaction network. First, a reaction network is divided into two parts. The first part is simulated via the GA, while the solution of the CME for the second part is fed into the GA in order to update its propensities. The advantage of this method is that it avoids the need to solve the CME or stochastically simulate the entire network, which makes it highly efficient. One of its drawbacks, however, is that most of the information about the second part of the network is lost in the process. Therefore, this method is most useful when only partial information about a reaction network is needed. We tested this method against the GA on two systems of interest in biology - the gene switch and the Griffith model of a genetic oscillator—and have shown it to be highly accurate. Comparing this method to four different stochastic algorithms revealed it to be at least an order of magnitude faster than the fastest among them.
Thermal response of human skin epidermis to 595‐nm laser irradiation at high incident dosages and long pulse durations in conjunction with cryogen spray cooling: An ex‐vivo study

Improved laser treatment of cutaneous hypervascular lesions is expected by utilizing higher incident dosages, longer pulse durations and longer wavelengths than those currently used in clinical settings. However, simply increasing the incident dosage will also increase the risk of nonspecific thermal injury to the epidermis due to light absorption by melanin. In this study, we investigated the thermal response of human skin epidermis to 595‐nm wavelength laser irradiation at high incident dosages (up to 20 J/cm2) and long pulse durations (up to 40 milliseconds) in conjunction with cryogen spray cooling (CSC) using ex‐vivo human skin samples.
Dimensions of Financial Autonomy in Low-/Moderate-Income Couples from a Gender Perspective and Implications for Welfare Reform

Abstract The ‘unitary household’ lives on in policymakers’ assumptions about couples sharing their finances. Yet financial autonomy is seen as a key issue in gender relations, particularly for women. This article draws on evidence from semi-structured individual interviews with men and women in thirty low-/moderate-income couples in Britain. The interviews explored whether financial autonomy had any meaning to these individuals; and, if so, to what extent this was gendered in the sense of there being differences in men's and women's understanding of it. We develop a framework for the investigation of financial autonomy, involving several dimensions: achieving economic independence, having privacy in one's financial affairs and exercising agency in relation to household and/or personal spending. We argue that financial autonomy is a relevant issue for low-/moderate-income couples, and that women are more conscious of tensions between financial togetherness and autonomy due to their greater responsibility for managing togetherness and lower likelihood of achieving financial independence. Policymakers should therefore not discount the aspirations of women in particular for financial autonomy, even in low-/moderate-income couples where there remain significant obstacles to achieving this. Yet plans for welfare reform that rely on means testing and ignore intra-household dynamics in relation to family finances threaten to exacerbate these obstacles and reinforce a unitary family model.
To investigate the Temporal and Spatial correlation behavioral characteristics of MIMO fading channels

This paper deals with the analysis of performance bounds of narrowband multiple-input multiple-output (MIMO) fading channels considering the transmission links from the mobile station (MS) to the base station (BS) through non-line-of-sight (NLOS) propagation conditions. It is assumed that an infinite number of local scatterers surround the MS and the BS. The Temporal as well as Spatial correlation properties of channel models are explored along with their capacity. The effect of number of scatterers; Doppler frequency; and isotropic/non-isotropic scattering conditions, on MIMO channel models is investigated in terms of statistical properties of one ring and two ring models, i.e. Time Autocorrelation Function (ACF) and two-dimensional (2D) Space Cross-correlation Function (CCF).
The new political voice of young Americans: Online engagement and civic development among first-year college students

We present findings from the first wave of a longitudinal study of civic and political engagement among undergraduate students at a mid-sized university in the Midwestern United States. We find that high school experiences of civic learning are a significant predictor of three of our four measures of civic and political engagement, namely, the likelihood of contacting a public official, participating in a protest, and engaging in collective problem-solving. Online political engagement appears to partially mediate the relationship between high school civic learning and offline political engagement. In terms of the specific aspects of high school civic learning that may be most salient to adolescents, the classroom experience of ‘meeting people who make society better’ emerges as the strongest predictor of students’ civic engagement. These findings suggest that citizenship norms among young adults may be shifting to new forums of engagement rather than simply eroding, as some current literature suggests.
Fibrinogen and FXIII dose response effects on albumin-induced coagulopathy

Abstract Objectives. Natural colloid albumin induces a lesser degree of dilutional coagulopathy than synthetic colloids. Fibrinogen concentrate has emerged as a promising strategy to treat coagulopathy, and factor XIII (FXIII) works synergistically with fibrinogen to correct coagulopathy following haemodilution with crystalloids. Our objectives were to examine the ability of fibrinogen and FXIII concentrates to reverse albumin-induced dilutional coagulopathy. Methods. High and low concentrations of both fibrinogen and FXIII were used to reverse coagulopathy induced by 1:1 dilution in vitro with 5% albumin of blood samples from healthy volunteers, monitored by rotational thromboelastometry (ROTEM®). Results. Haemodilution with albumin significantly attenuated EXTEM maximum clot firmness (MCF), alpha angle (AA), clotting time (CT) and clot formation time (CFT), and FIBTEM MCF (p < 0.001). Following haemodilution, both doses of fibrinogen significantly corrected all ROTEM parameters (p ≤ 0.02), except the lower dose did not correct AA. Compared to the lower dose, the higher dose of fibrinogen significantly improved FIBTEM MCF and EXTEM MCF, AA and CFT (p < 0.001). The lower dose of FXIII did not significantly correct any of the ROTEM parameters, and the high dose only improved EXTEM CT (p = 0.004). All combinations of high/low concentrations of fibrinogen/FXIII significantly improved all ROTEM parameters examined (p ≤ 0.001). Fibrinogen concentration generally had a greater effect on each parameter than did FXIII concentration; the best correction of ROTEM parameters was achieved with high-dose fibrinogen concentrate and either low- or high-dose FXIII. Conclusions. Fibrinogen concentrate successfully corrected initiation, propagation and clot firmness deficits induced by haemodilution with albumin, and FXIII synergistically improved fibrin-based clot strength.
A hybrid intelligent system for 3D reconstruction from a single line drawing

In automatic reconstruction of 3D objects from single line drawings, existing systems are all single-track, containing one general solution for all drawings. This paper proposes a method in which an input drawing is first classified based on dominant features which exist in the drawing, including symmetry, orthogonality and parallelism. The reconstruction is then performed by experts to deal with each class specifically. Drawing classification is done using the technique of support vector machine classification. A specific set of features are selected to form an optimal regularity set for each class, and used in the formulation of the objective function for effective reconstruction. Experimental results show that the proposed system can improve the reconstruction accuracy and efficiency than that of a single-track general 3D reconstruction system.
Reference Dependence and Politicians' Credibility

We consider a model of electoral competition in which two politicians compete to get elected. Each politician is characterized by a valence, which is unobservable to voters and can take one of two values: high or low. The electorate prefers politicians with high valence, but random shocks may lead to the victory of low-valence ones. Candidates make statements concerning their valence. We show that if voters are standard expected utility maximizers, politicians' statements lack any credibility and no information transmission takes place. By introducing reference-dependent preferences and loss aversion a lA Koszegi and Rabin, we show that full revelation is possible. Indeed, if the electorate believes to candidates' announcements, such announcements will affect its reference point. As a result, if voters find out that a candidate lied, pretending to be high valence when she is not, they may decide to support the opponent in order to avoid the loss associated with appointing a candidate worse than expected.

Para conseguir captar el interes de los jugadores is importante que los video juegos adapten su dificultad en funcion de las habilidades del jugador. Ser capaz de evaluar como juegan los usuarios es un componente crucial para modelar el comportamiento de los jugadores en los juegos. Uno de los problemas de crear un modelo de comportamiento de usuario es comprobar si las variable predictoras detectan correctamente las acciones del jugador. En este articulo, estudiaremos el juego de codigo abierto Tower Defense (Open-source Tower Defence OTD), basado en un tablero 2D en el que aparecen conjunto de hordas enemigas que deben ser destruidas para evitar que alcancen la salida. Utilizando dicho juego extraeremos en tiempo real la informacion de las interacciones usuario y los eventos del juego utilizando la tecnica de ventana deslizante. Una vez obtenida suficiente informacion, el modelo se evaluara mediante tecnicas de clustering (concretamente, K-Means y Spectral Cluster). Finalmente, estudiaremos la similitud entre las diferentes partidas donde los jugadores han utilizado diferentes estrategias.
A FYVE zinc finger domain protein specifically links mRNA transport to endosome trafficking

An emerging theme in cellular logistics is the close connection between mRNA and membrane trafficking. A prominent example is the microtubule-dependent transport of mRNAs and associated ribosomes on endosomes. This coordinated process is crucial for correct septin filamentation and efficient growth of polarised cells, such as fungal hyphae. Despite detailed knowledge on the key RNA-binding protein and the molecular motors involved, it is unclear how mRNAs are connected to membranes during transport. Here, we identify a novel factor containing a FYVE zinc finger domain for interaction with endosomal lipids and a new PAM2-like domain required for interaction with the MLLE domain of the key RNA-binding protein. Consistently, loss of this FYVE domain protein leads to specific defects in mRNA, ribosome, and septin transport without affecting general functions of endosomes or their movement. Hence, this is the first endosomal component specific for mRNP trafficking uncovering a new mechanism to couple mRNPs to endosomes. DOI: http://dx.doi. org/10.7554/eLife.06041. 001
Inferring motion uncertainty from shape-Matching

This paper proposes a novel method for computing robot motion uncertainty from ranging sensor data. The method utilises the recently proposed CRF-Matching procedure which matches laser scans based on shape descriptors. Motion estimates are computed in a probabilistic framework by performing inference on a probabilistic graphical model. We propose an efficient sampling procedure for obtaining probable association hypothesis of the probabilistic graphical model. The hypothesis are used to generate estimates on the uncertainty of translational and rotational movements of the robot. Experiments demonstrate the benefits of the approach on simulated data sets and on laser scans from an urban environment. The approach is also combined with the well-established delayed-state information filter for a large-scale outdoor simultaneous localisation and mapping task.
Study of the Corrosion Resistance of Austenitic Stainless Steels during Conversion of Waste to Biofuel

The paper deals with the corrosion behavior of stainless steels as candidate materials for biofuel production plants by liquefaction process of the sorted organic fraction of municipal solid waste. Corrosion tests were carried out on AISI 316L and AISI 304L stainless steels at 250 °C in a batch reactor during conversion of raw material to bio-oil (biofuel precursor), by exposing specimens either to water/oil phase or humid gas phase. General corrosion rate was measured by weight loss tests. The susceptibility to stress corrosion cracking was evaluated by means of U-bend specimens and slow stress rate tests at 10−6 or 10−5 s−1 strain rate. After tests, scanning electron microscope analysis was carried out to detect cracks and localized attacks. The results are discussed in relation with exposure conditions. They show very low corrosion rates strictly dependent upon time and temperature. No stress corrosion cracking was observed on U-bend specimens, under constant loading. Small cracks confined in the necking cone of specimens prove that stress corrosion cracking only occurred during slow strain rate tests at stresses exceeding the yield strength.
Temperature Trends in the Lower Atmosphere

A new publication by NOAA (US National Oceanic and Atmospheric Administration) claims to have removed the previously evident discrepancies between mean global temperature anomalies measured on the surface and those measured in the lower troposphere. It claims that a combination of attention to inaccuracies and the use of linear regression equations on selected climate sequences have removed these discrepancies. This paper shows that these claims are untrue. The apparent agreement of the two sets of records for the chosen sequences is dependent on the enhanced influence of volcanoes and El Niño events in the lower troposphere, compared with an additional warming factor on the surface. If a temperature sequence comparatively free from these influences, (1979–1997) is chosen, there is no significant warming in the lower atmosphere for six of the seven records, and for the seventh, no significant warming between 1988 and 1997; whereas warming still prevails on the surface over these periods. The supposed enhanced greenhouse effect is thus currently undetectable in the lower atmosphere, where it is supposed to be most prominent, for extended periods, so the warming on the surface over these periods must have some other cause.
Symbiotic Relationship Between Emotional Intelligence And Collegial Leadership

Research on leadership over the past two decades suggests that the emotional intelligence of leaders matters twice as much as that of cognitive abilities, such as IQ or technical expertise. Emotionally intelligent leaders experience a greater sense of well-being, improved relationships, happier employees and lower employee turnover, better team work, greater job satisfaction and a greater degree of success. Four hundred and seventy four employees participated in this study. The quantitative research method was used to examine the employees’ perceptions of their leaders’ emotionally intelligent personal and social skills on their job satisfaction. Findings in this study strongly suggest that collegial leaders demonstrate high levels of EI and collegiality in the working environment. These collegial leaders are equipped with personal and social skills which they use to contribute to the happiness and job satisfaction of their workers. Integral to the success and development of the collegial process is that employees feel that they are being nurtured in an open, warm and sincere environment. Clearly, a leader who demonstrates appropriate levels of emotionally intelligent personal and social skills will not only create a collegial working environment but will also thrive in one. The evidence emanating from this exploratory study confirms that there is a symbiotic relationship between emotional intelligence and collegial leadership. The emotionally intelligent collegial leader is a concept that extends far beyond a slogan and must become an integral part of organizational effectiveness and reform. It is inconceivable to speak about collegial leadership in the absence of emotional intelligence.
Rock-paper-scissors prediction experiments using muscle activations

Human motion prediction is becoming more and more important issue in the filed of wearable robots or biorobotics. This paper provides an initial experimental result for human motion prediction. In detail, the prediction method for ternary choice among rock-paper-scissors is presented using temporal patterns of muscle activations (Electromyography, in short EMG) controlling hand motion of subject. Initial burst part of EMG is prior to the onset of actual movement by dozens to hundreds milliseconds. Using this property, the proposed method makes the ternary choice prediction among rock-paper-scissors as soon as 10% motion variation of any finger is detected. It is shown experimentally that the success rate of the proposed prediction method is over 95%.
Collaborative Information Seeking : A Theoretical and Methodological Critique

This paper is intended to provide an informal assessment of the theoretical foundations and methodological applications that have been used to study collaborative information seeking. The review of previous studies on collaborative information seeking reveals that most studies have been predominantly descriptive and exploratory in nature, and little has been based on existing conceptual or theoretical foundation. It was also found that there is an observable preference toward qualitative studies using observation and interviews.
Effects of aging on capillary geometry and hemodynamics in rat spinotrapezius muscle.

The effects of aging on muscle microvascular structure and function may play a key role in performance deficits and impairment of O2 exchange within skeletal muscle of senescent individuals. To determine the effects of aging on capillary geometry, red blood cell (RBC) hemodynamics, and hematocrit in a muscle of mixed fiber type, spinotrapezius muscles from Fischer 344 x Brown Norway hybrid rats aged 6-8 mo [young (Y); body mass 421 +/- 10 g, n = 6] and 26-28 mo [old (O); 561 +/- 12 g, n = 6] were observed by high-resolution transmission light microscopy under resting conditions. The percentage of RBC-perfused capillaries (Y: 78 +/- 3%; O: 75 +/- 2%) and degree of tortuosity and branching (Y: 13 +/- 2%; O: 13 +/- 2%, additional capillary length) were not different in O vs. Y muscles. Lineal density of RBC-perfused capillaries in O was significantly reduced (Y: 30.7 +/- 1.8, O: 22.8 +/- 3.1 capillaries/mm; P < 0.05). However, RBC-perfused capillaries from O rats (n = 78) exhibited increased RBC velocity (VRBC) (Y: 219 +/- 12, O: 310 +/- 14 microm/s; P < 0.05) and RBC flux (FRBC) (Y: 27 +/- 2, O: 41 +/- 2 RBC/s; P < 0.05) vs. Y rats (n = 66). Thus O2 delivery per unit of muscle was not different between groups (Y: 894 +/- 111, O: 887 +/- 118 RBC. s-1. mm muscle-1). Capillary hematocrit was not different in Y vs. O rats (Y: 26 +/- 1%, O: 28 +/- 1%: P > 0.05). These data indicate that in resting spinotrapezius muscle, aging decreases the lineal density of RBC-perfused capillaries while increasing mean VRBC and FRBC within those capillaries. Whereas muscle conductive O2 delivery and capillary hematocrit were unchanged, elevated VRBC reduces capillary RBC transit time and may impair the diffusive transport of O2 from blood to myocyte particularly under exercise conditions.
Epstein-Barr virus provides a survival factor to Burkitt's lymphomas

Epstein-Barr virus (EBV) has been causally associated with at least five human malignancies. The exact contributions made by EBV to these cancers remain unknown. We demonstrate that one viral protein found in all EBV-associated malignancies, Epstein-Barr nuclear antigen 1 (EBNA-1), is required for survival of one of these cancers, EBV-positive Burkitt's lymphoma. Inhibition of EBNA-1 decreases survival of these tumor cells by inducing apoptosis. Expression of EBNA-1 in uninfected cells also can inhibit apoptosis induced by expression of p53 in the absence of the EBV genome. Our findings demonstrate that EBNA-1 is critical for the continued survival of EBV-associated Burkitt's lymphoma, and, by extension, for the other B cell tumors with which EBV is associated. Efficient inhibitors of EBNA-1's functions would likely prove useful in the therapy of EBV-associated malignancies.
Empirical Bayes Combination of Estimated Areas under ROC Curves Using Estimating Equations

A synthesis of the empirical Bayes method and the method of estimating equations is used to combine individual receiver operating characteristic (ROC) area estimates from different studies of the same diagnostic test into a single estimate. This single estimate represents the population mean from which individual areas under the ROC curves were sampled. The only data needed to carry out the method are estimated areas under the ROC curves and the corresponding standard errors. Key words: ROC curves; empirical Bayes method.
