Correlated X-ray/optical variability in the quasar MR 2251−178

Emission from active galactic nuclei is known to vary strongly over time over a wide energy band, but the origin of the variability and especially of the interband correlations is still not well established. Here we present the results of our X-ray and optical monitoring campaign of the quasar MR 2251? 178, covering a period of 2.5 years. The X-ray 2–10 keV flux is remarkably well correlated with the optical B, V and R bands, their fluctuations are almost simultaneous with a delay consistent with 0 d and not larger than 4 d in either direction. The amplitude of variations shows an intriguing behaviour: rapid, large amplitude fluctuations over tens of days in the X-rays have only small counterparts in the optical bands, while the long-term trends over hundreds of days are stronger in the B band than in X-rays. We show that simple reprocessing models, where all the optical variability arises from the variable X-ray heating, cannot simultaneously explain the discrepant variability amplitudes on different time-scales and the short delays between X-ray and optical bands. We interpret the variability and correlations, in the optically thick accretion disc plus corona scenario, as the result of intrinsic accretion rate variations modulating both X-ray and optical emission, together with reprocessing of X-rays by the accretion disc.
Power Dispatch Strategy for Interconnected Microgrids Based Hybrid Renewable Energy System

This paper proposes a studied system made up of interconnected microgrids (MGs) in which each one includes a hybrid renewable energy system (HRES). The proposed power dispatch strategy ensures load satisfaction in each MG by maintaining the equilibrium between production and consumer demand powers via interactions among MGs and the utility grid. The purpose of this paper is to provide an adequate supply to the different MGs by adapting production to consumption according to the available hybrid power production. This is done with the consideration of the dispatch of the power exchanged among MGs and the main grid. The cooperation between the multiples MGs ensures higher resilience and ﬂexibility of the whole distribution system. The case study results are provided to show the feasibility of this proposed power dispatch strategy in the smart grid environment.
Exploration of Transfer of Control Rights of the Largest Shareholder

After the completion of the split share reform, which aims to coordinate the interests of the shareholders, improve the corporate governance mechanism and maintain the long-term development of the capital market, China's capital market has entered the full circulation era. However, under the background of full circulation, China's "listed companies' equity concentration anomalies" have not been fundamentally relieved, while the largest shareholders have lost their holding position in the capital market. Thus, a new round of "vision of transfer of the control right of the first largest shareholders" emerged. On the basis of combing and analyzing the existing research literature system at home and abroad, the empirical findings of the transfer of control rights of first largest shareholder in the A stock market of China from 2012 to 2016 are found: after full circulation, the transfer control rights of first largest shareholder is still serious; the first largest shareholder of listed companies involved in the transfer of control rights is the computer, communications and other electronic equipment manufacturing industry, followed by the electrical machinery and equipment manufacturing industry; corporate investors, other corporate investors, and public shares (circulating A shares) investors account for the majority of the shares transferred by the first largest shareholder of the listed company; Judging from the nature of the company, private enterprises are more vulnerable to the transfer of control of the first largest shareholder. This research conclusion provides a new perspective for governance of the “vision of transfer of control rights of first largest shareholder” in different industries. Keywords—Full circulation; First largest shareholder; Transfer of control
High survival rates of kidney transplants from spousal and living unrelated donors.

BACKGROUND In the United States, increasing numbers of persons are donating kidneys to their spouses. Despite greater histoincompatibility, the survival rates of these kidneys are higher than those of cadaveric kidneys. We examined the factors influencing the high survival rates of spousal-donor kidneys. METHODS Kidney-transplant data from the United Network for Organ Sharing Renal Transplant Registry were used to calculate graft-survival rates with Kaplan-Meier analysis. RESULTS The three-year survival rates were 85 percent for kidneys from 368 spouses, 81 percent for kidneys from 129 living unrelated donors who were not married to the recipients, 82 percent for kidneys from 3368 parents, and 70 percent for 43,341 cadaveric kidneys. The three-year survival rate for wife-to-husband grafts was 87 percent, which was the same as for husband-to-wife grafts if the wife had never been pregnant. If the wife had previously been pregnant, the three-year graft-survival rate was 76 percent (P = 0.40). The three-year graft-survival rate among recipients of spousal grafts who did not receive transfusions preoperatively was 81 percent, as compared with 90 percent for recipients who received 1 to 10 transfusions preoperatively (P = 0.008). The superior survival rate of grafts from unrelated donors could not be attributed to better HLA matching, white race, younger donor age, or shorter cold-ischemia times, but might be explained by damage due to shock before removal in 10 percent of the cadaveric kidneys. CONCLUSIONS Spouses are an important source of living-donor kidney grafts because, despite poor HLA matching, the graft-survival rate is similar to that of parental-donor kidneys. This high rate of survival is attributed to the fact that the kidneys were uniformly healthy.
Social Media Information and Analyst Forecasts

Purpose The purpose of this paper is to examine whether corporate social media information helps improve analysts’ forecast accuracy. Design/methodology/approach This study uses hand-collected information on S&P 500 firms’ official Facebook pages and uses posts and reactions to such posts to measure corporate Facebook information. Multivariate regression models are estimated to test the relationship between analysts’ forecast accuracy and corporate Facebook information. Findings The results indicate that analysts forecast accuracy is unresponsive to posts. However, analyst forecast errors are decreasing in reactions to posts. These findings are robust to the inclusion of control variables, firm and time fixed effects, and alternative specifications of forecast errors and different pre-forecast time windows. Research limitations/implications This study has some limitations. It focuses only on the S&P 500 firms, which are large and generally provide better information to the market. The sample period coincides with the early period of the corporate Facebook culture. However, more recent data sets are likely to provide stronger results. Practical implications The findings of this study provide support for “information generation” role of social media and show that reactions to corporate Facebook posts are the new and unique information generated from corporate social media activities, which help information intermediaries in improving their forecasting accuracy. Originality/value This study makes an important contribution to the literature by separating the information dissemination role of social media from information generation role and establishes the first evidence on how corporate social media information affects forecast accuracy of financial analysts.

Correlations between fatty acid distribution in phospholipids and the temperature dependence of membrane physical state.

Cytoplasmic membranes of an unsaturated fatty acid auxotroph of Escherichia coli have been studied using spin labeled hydrocarbon probes. These studies reveal that the membrane lipids undergo changes of state at critical temperatures which reflect the physical properties of the fatty acid supplement supplied to the cells during growth. The critical temperatures observed in spin labeled membranes correlate with characteristic temperatures in membrane functions. Lipid analysis reveals that fatty acid composition and distribution in membrane phospholipids are primary determinants of the temperatures at which changes of state are observed in membrane lipids. Fatty acid composition and distribution can also produce unique interactions between certain spin label probes and their lipid environment.

A New Method for Traffic Prediction in Emerging Mobile Networks

With the increasing popularity of mobile devices and applications, emerging mobile network traffic exhibits special characteristics in temporal scale e.g., there is a scale variance between the network traffic on weekdays and on weekends. Although most existing methods have been applied to data traffic prediction, few of them take such characteristic into consideration. In this paper, by using real data in mobile networks, we adopt the entropy theory to reveal that the duration of time-series given for prediction doesn't always have a positive impact and that the uncorrelated preceding time-series also deteriorates the prediction accuracy. In view of this, partitioning the network traffic prediction into weekdays’ and weekends’ perspective, we propose a method to predict the data traffic. Finally, we evaluate the proposed method through predicting the data traffic for a future time according to the historical data traffic in a real mobile network. In comparison with the work based on ARMA (Auto Regressive Moving Average) method, our proposed method can reduce the Mean Absolute Percentage Error (MAPE) by 35.7% and 43.8% on weekdays’ and weekends’ prediction, respectively.
Assessing Value From Business-to-Business Services Relationships: Temporality, Tangibility, Temperament, and Trade-Offs

Theoretical contributions exploring service value in business-to-business (B2B) settings have significantly lagged those that consider goods markets and business-to-consumer (B2C) contexts. To address this gap, this article focuses on the interfirm relationship as the fulcrum through which service value is created and exchanged. Specifically, we analyze how relationship value is assessed by actors and their organizations over the lifetimes of service engagements. Through in-depth interviews with 38 executives representing customer and provider firms, we study three cases with durations ranging between 9 and 11 years. We develop a model demonstrating value assessment to be a dynamic, socially constructed, and multilevel phenomenon, in which structured institutional bodies and unstructured collectives within firms display different priorities in their assessments. The model also demonstrates the critical role of relationship leaders in influencing these positions and negotiating consensus. Our analysis reveals value assessments to be both a sustenance for, and an output from, B2B service relationships. We contribute to knowledge and theory of relationship value and offer managerial actions to promote improvement in assessments of this value in B2B services settings.

Purpose of review To provide an overview of available evidence of the relationship between birth weight and future hypertension development. Recent findings Fetal programming plays a significant role in future hypertension. Both low and high birth weight are able to influence weight gain during childhood, adult weight and blood pressure values during childhood and adulthood. To date, an increasing amount of evidence is available especially for the relationship between low birth weight and hypertension, supported also by pathophysiological studies. Summary In the era of personalized medicine, the possibility to reduce cardiovascular risk before or soon after birth and intervene on risk factors during childhood is appealing and promising for the future.
Digital Probabilistic Atlas of the Border Region between the Middle and Posterior Cerebral Arteries

Background and Purpose: The diagnosis of external borderzone infarction is made when the stroke is located at the border between the arterial territories. Recent studies have raised questions regarding the location of this borderzone given the variability in the arterial territories. We examined the location of this region using a digital approach and its correspondence with the ‘traditional’ template. Methods: Infarcts resulting from occlusion of the middle cerebral artery (MCA) or posterior cerebral artery (PCA) trunk or branches were segmented from T2-weighted MR images and linearly registered into a common stereotaxic coordinate space. For MCA infarcts and PCA infarcts, maps of voxels in a rim surrounding the infarct were created. The maps of individual rims were averaged to create images of the probability of each voxel lying in the MCA and PCA rims. The MCA and PCA rims were used to create a digital atlas of the probability of each voxel lying concurrently in both rims. Results: The MCA group consisted of 36 patients (16 males) with a median age of 73 (range 25–87) years. The PCA territory group consisted of 30 patients (24 males) with a median age of 61 (range 22–86) years. The probability of involvement in the digital atlas was higher in the posterior putamen (probability 0.12–0.29) and optic tract (probability 0.13–0.0.20) than in the angular gyrus (probability 0.01). Conclusion: We have created a digital model of the border region between the MCA and PCA territories. This approach may be useful for evaluating the likelihood of a stroke mechanism from topography.

Pengaruh brand experience terhadap brand loyalty melalui brand satisfaction dan brand attitude

Competition in an increasingly competitive market today, requires the company to be able to compete through brand competition. It is important for company to produce valuable products which fulfill consumer’s needs with quality and good brands, in order to maintain customer loyalty. It is also experienced by the very well known coffee shop brand, Starbucks Coffee. Consumer who consume the products, certainly have experience when conducting a transaction of products or services with that brands (brand experience). In addition, the brands also continues to prioritize customer delight as the key to satisfy their consumers (brand satisfaction) and build a positive attitude towards the consumers (brand attitude). Therefore, it can increase consumer loyalty towards the brands (brand loyalty). This study discusses the influence of brand experience towards brand loyalty through brand satisfaction and brand attitude. This research was conducted by taking data samples of 300 respondents from a population of customers who consume the products through filling questionnaires. After the research data was obtained, the calculations were done using SPSS 20.0 for windows to get the statistic results between the variables examined in this study. The results obtained from this study is there is a positive and significant influence between the variables of brand experience on brand satisfaction, there is a positive and significant influence between the variables of brand experience on brand attitude, there is a positive and significant influence between the variables of brand experience on brand loyalty, there is a positive and significant influence between the variables of brand satisfaction on brand loyalty, and there is a positive and significant influence between the variables of brand attitude on brand loyalty.
Interferón en el tratamiento del melanoma

Objetivo: Determinar mejor dosis y resultados del tratamiento del melanoma en base a Interferon. Material y metodos: Revisamos la bibliografia publicada a nivel internacional de los ultimos veinte anos y las comunicaciones bibliograficas en base a la utilizacion del Interferon en sus diferentes formas farmaceuticas. Resultados: Se ha evaluado el INF a, b, g y pegilado en diferentes dosis y con distintos resultados. En adyuvancia en melanoma est. II y III: a baja dosis 3M ui 3v por sem. por 3 a, no impacta ni en SV ni en SVLE; a dosis altas de 20m ui 5 v por sem. por 4 sem. y luego 10 M ui 3 v por sem. por 48 sem. no impacta en SV a largo plazo pero si en SVLE ( plan de Kirkwood). A dosis intermedias: 10 M ui 5 v por sem. por 4 sem. y luego 10m ui 3 v por sem. por 48 o 96 sem. no impacta en SV mientras esta en evaluacion el resultado en SVLE. En la enfermedad diseminada metastasica se postula un 15% de RG con mejores resultados para la alta dosis. Se necesita mayor comprobacion en resultados de ensayos clinicos. Discusion: La utilizacion del INF en sus diferentes formas farmaceuticas no ha demostrado impacto en la SV ni en adyuvancia ni en la enfermedad diseminada. Se discute cual es el mejor plan en funcion de la SVLE en tratamientos paliativos dados los muy importantes efectos secundarios de dicha medicacion que generalmente no ha permitido realizar los planes completos de tratamiento con alta dosis al 48 % de los pacientes incluidos en los ensayos clinicos. La decision pasa por determinar que plan tiene mayor impacto, el pico agudo de la alta dosis o el tratamiento antenido de las dosis intermedias a largo plazo. El agregado del INF al tratamiento del melanoma metastasico a los planes de QT no aumentan los resultados y si los efectos toxicos del tratamiento.
Empirical essays on the roles of news media in an urban economy

Economists typically assume perfect information, but households are not always well informed, and face a high degree of uncertainty regarding the quality of goods or value of their assets. As a consequence, information from mass media is a main part of our everyday lives. Coverage in popular media outlets can catch the attention of millions of households and, therefore, news media may influence their decisions in several ways. This thesis investigates the roles of news media in an urban economy and for housing markets. Each of the three empirical essays provides insights into how information from the media can shape the economic decisions of households as either homebuyers, homeowners, or consumers. While the first and the second chapters estimate the causal effects of publicity, in particular positive information, on house prices and non-housing consumption, respectively, the last chapter explores how media coverage may affect the link between house prices and homeowner spending. This thesis places particular emphasis on understanding the mechanisms through which news media may affect economic outcomes by empirically identifying potential channels.
Ultra-Low Temperature FOWLP Process for the Embedding of Low Thermal Budget Sensors and Components Using SU-8 as Dielectric

Fan-Out Wafer Level Packaging (FOWLP) has recently seen a tremendous growth in a broad span of application in telecommunications, automotive and other markets. Its versatility allows its continuous development to accommodate more and more types of components. In light of expanding the technology to include new family of sensors such as MEMS/NEMS, Bio-chips with Microfluidics, magneto-resistive devices and Micro-batteries, the upper limit temperature of FOWLP processing has to be challenged. FOWLP, namely the WLFO technology of NANIUM, based on Infineon/ Intel eWLB technology, is a packaging technology based on wafer reconstitution and RDL processes. The “LTC - low temperature cure” dielectrics used today, are cured at > 200ºC, while solder ball soldering peaks ~260ºC. Despite being considered low temperature, this limit is still not compatible and considered high to a wide range of the new family of sensors targeted to integrate in WLFO. In this work we describe the strategy to lower overall process temperature to
Formulating a Clinical Practice Care Plan for the Diagnosis and Assessment of Alzheimer's Disease

Abstract Alzheimer's disease is a devastating neurological disorder characterized by cognitive deficits, functional impairment, and often troublesome behavioral symptoms. Unfortunately, Alzheimer's disease can be difficult to diagnose at early and even moderate stages of the disease. This article outlines simple, efficient strategies for identifying patients with potential dementia. The discussion focuses on the key components of a comprehensive assessment plan, which typically involves taking the patient's history, as well as conducting cognitive testing, laboratory testing, neurologic examination, and neuroimaging to evaluate patients for Alzheimer's disease. Finally, opportunities for the improvement of care are discussed, with an emphasis on overcoming barriers to diagnosis such as time limitations and reimbursement issues.
Porous, Crystalline, Covalent Organic Frameworks

Covalent organic frameworks (COFs) have been designed and successfully synthesized by condensation reactions of phenyl diboronic acid {C6H4[B(OH)2]2} and hexahydroxytriphenylene [C18H6(OH)6]. Powder x-ray diffraction studies of the highly crystalline products (C3H2BO)6·(C9H12)1 (COF-1) and C9H4BO2 (COF-5) revealed expanded porous graphitic layers that are either staggered (COF-1, P63/mmc) or eclipsed (COF-5, P6/mmm). Their crystal structures are entirely held by strong bonds between B, C, and O atoms to form rigid porous architectures with pore sizes ranging from 7 to 27 angstroms. COF-1 and COF-5 exhibit high thermal stability (to temperatures up to 500° to 600°C), permanent porosity, and high surface areas (711 and 1590 square meters per gram, respectively).
