Experimental and First Principles Theoretical Study of Structural and Electronic Properties in Tantalum Doped In2O3 Semiconductor: Finding a Definitive Hyperfine Interaction Assignment

In this work we present an experimental and theoretical study from first principles of the structural, electronic, and hyperfine properties of Ta doped In2O3 semiconductor. The ab initio electronic structure calculations in the Ta diluted In2O3 system enabled to obtain the structural lattice distortions and the hyperfine parameters when the Ta atom is placed at each cationic site of the bixbyite crystal structure. To this purpose we used the full potential augmented plane wave plus local orbital (FP APW+lo) method, within the density functional theory. The obtained results indicate that the substitutional Ta probe impurity produces strong changes on the local structure. In addition, we performed accurate time differential perturbed g g angular correlations (TDPAC) key experiments in 181Hf( 181Ta) implanted In2O3 samples with high crystallinity, in order to obtain high quality measurements of the electric field gradient tensor (EFG) that unraveled the controversy settled in the literature and overcome diss.
Assessing the market potential of electric bicycles and ICT for low carbon school travel: a case study in the smart city of Agueda

Electric bikes (e bikes) may help in transport decarbonisation in European cities. To fully assess the market potential of e bikes, further research is needed to understand users' preferences and the range of factors that can contribute for people to shift from car use to low carbon vehicles such as e bikes. This paper is built on the Be4Schools R&D project implemented in the city of Agueda which is considered the first smart city in Portugal. It comprised the former study in the country that examined the willingness of students (aged 15 21 years) to use e bikes for daily trips to school and that gathered their preferences towards specific ICT related attributes. The methodology comprised a mobility survey and a stated choice experiment (SC) The SC experiment gathered 2232 observations which were able to provide the relevant attribute trade off information between car travel and e bike (with or without specific ICT equipment) An extensive econometric analysis was performed to assess the nature and extent of students' heterogeneity of preferences which also considered gender issues. The study aimed to contribute to the regional economic cluster on powered two wheels' industry innovation. Research results are interesting for city mobility policies and the regional industry as the possible integration of ICT equipment in e bikes may speed up the market uptake of this technology.
Inferring weekly primary activity patterns using public transport smart card data and a household travel survey

With the introduction of smart cards for electronic payment in public transport, massive spatio temporal data have been recorded in many cities. This data represents how public transport users from a whole city or country travel during consecutive days or weeks. This work presents a method to identify temporal weekly patterns of primary activities performed by public transport users in Singapore. As continuous travel data from the same user during a week can be extracted, work leisure cycles can be recognized. Using revealed trips from a 1% sample household travel survey, activities reached and left by public transport were extracted and used to develop two discrete choice models: one for workers and one for students. According to the start time and duration of an activity, these models estimate the likelihood of such activity to be HOME, WORK/STUDY or OTHER type. Then, consistent activities were extracted from public transport smart card transactions recorded during one week. Using the discrete choice models, these extracted activities were classified by type. For each user, a 14 dimension vector summarizes his/her primary activity pattern. Each vector is composed by start time and duration of his/her work or study activities during continuous 7 days. To recognize the most common primary activity patterns of the city, the DBSCAN clustering algorithm was applied to these vectors. As the input data of this method is commonly available, the method can be applied to many cities in the world.
Rising Population and Food Insecurity Linkages in Pakistan: Testing Malthusian Population Growth Theory

Specific amount of food and safe drinking water are basic necessities of living human beings. The human population of the universe is touching its highest level and counted more than seven billion, it is going towards facing a great famine as predicated by Malthus (1798) The positive and preventive checks of Malthus (1798) can be observed empirically in different parts of the world (Swaminathan and Feng 1994) The study has tested the population theory of Malthus in case of Pakistan. For investigating the long run relationship among the variables of the model Johanson cointegration technique is applied. For examining the short run dynamic Error Correction Model (ECM) is applied. The results of the study of the study supported that the Malthusian theory about the population and income growth in the case of Pakistan. Furthermore, higher population growth rate increases the food insecurity not only in long run but also in short run in case of Pakistan.
An Algebra and Equivalences to Transform Graph Patterns in Neo4j
Venue: EDBT/ICDT Workshops

Modern query optimizers of relational database systems embody more than three decades of research and practice in the area of data management and processing. Key advances include algebraic query transformation, intelligent search space pruning, and modular optimizer architectures. Surprisingly, many of these contributions seem to have been overlooked in the emerging field of graph databases so far. In particular, we believe that query optimization based on a general graph algebra and its equivalences can greatly improve on the current state of the art. Although some graph algebras have already been proposed, they have often been developed in a context, in which a relational database system is used as a backend to process graph data. As a consequence, these algebras are typically tightly coupled to the relational algebra, making them unsuitable for native graph databases. While we support the approach of extending the relational algebra, we argue that graph specific operations should be defined at a higher level, independent of the database backend. In this paper, we introduce such a general graph algebra and corresponding equivalences. We demonstrate how it can be used to optimize Cypher queries in the setting of the Neo4j native graph database.
Tensor fusion of social structural and functional analytics over Neo4j
Venue: 2016 7th International Conference on Information, Intelligence, Systems Applications (IISA)

For large directed graphs ranking vertices is an algorithmic as well as a computational challenge. Also it is a cornerstone problem in fields so diverse such as online social media, combinatorial optimization, deep learning, econometrics, and computational neuroscience. Gell point centrality metric is a common case of structural vertex ranking which can be efficiently computed through power method. This paper proposes harmonic centrality, also a structural ranking which can be computed equally efficiently. When the graph represents a network, both methods are oblivious to its functionality. To address that issue, a tensor based methodology is proposed for combining functional characteristics with these structural metrics. As a concrete demonstration, the tensor fusion methodology was implemented in Java over Neo4j and Tensor toolbox and was applied to a Twitter subgraph. The functional features were directly related to affective computing, while the hashtags in this subgraph were relared to a current controversial political topic, namely #brexit.
Tensor based document retrieval over Neo4j with an application to PubMed mining
Venue: 2016 7th International Conference on Information, Intelligence, Systems Applications (IISA)

PubMed mining is currently at the epicenter of intense interdisciplinary research. Text mining methodologies provide a way to retrieve and analyze emotionally charged words, punctuation, and syntax. Moreover, they can analyze scientific literature and process document collections. Moving beyond traditional document term matrix representation, an architecture for content based retrieval from PubMed is proposed whose core is a document term author third order tensor. This methodology has been implemented in Python over Neo4j and has been applied to a PubMed document article collection.
FPGA Hardware Acceleration of Monte Carlo Simulations for the Ising Model
Venue: IEEE Transactions on Parallel and Distributed Systems

A two dimensional Ising model with nearest neighbors ferromagnetic interactions is implemented in a Field Programmable Gate Array (FPGA) board. Extensive Monte Carlo simulations were carried out using an efficient hardware representation of individual spins and a combined global local LFSR random number generator. Consistent results regarding the descriptive properties of magnetic systems, like energy, magnetization and susceptibility are obtained while a speed up factor of approximately six times is achieved in comparison to previous FPGA based published works and almost <inline formula><tex math notation="LaTeX"$10^4$/tex math><alternatives> <inline graphic xlink:type="simple" xlink:href="ortegazamorano ieq1 2505725.gif"/alternatives>/inline formula> times in comparison to a standard CPU simulation. A detailed description of the logic design used is given together with a careful analysis of the quality of the random number generator used. The obtained results confirm the potential of FPGAs for analyzing the statistical mechanics of magnetic systems.

Computed tomography coronary angiography in patients with acute myocardial infarction and normal invasive coronary angiography
Venue: BMC Cardiovascular Disorders

BackgroundThree to five percent of patients with acute myocardial infarction (AMI) have normal coronary arteries on invasive coronary angiography (ICA) The aim of this study was to assess the presence and characteristics of atherosclerotic plaques on computed tomography coronary angiography (CTCA) and describe the clinical characteristics of this group of patients.MethodsThis was a multicentre, prospective, descriptive study on CTCA evaluation in thirty patients fulfilling criteria for AMI and without visible coronary plaques on ICA. CTCA evaluation was performed head to head in consensus by two experienced observers blinded to baseline patient characteristics and ICA results. Analysis of plaque characteristics and plaque effect on the arterial lumen was performed. Coronary segments were visually scored for the presence of plaque. Seventeen segments were differentiated, according to a modified American Heart Association classification. Echocardiography performed according to routine during the initial hospitalisation was retrieved for analysis of wall motion abnormalities and left ventricular systolic function in most patients.ResultsTwenty five patients presented with non ST elevation myocardial infarction (NSTEMI) and five with ST elevation myocardial infarction (STEMI) Mean age was 60.2 years and 23/30 were women. The prevalence of risk factors of coronary artery disease (CAD) was low. In total, 452 coronary segments were analysed. Eighty percent (24/30) had completely normal coronary arteries and twenty percent (6/30) had coronary atherosclerosis on CTCA. In patients with atherosclerotic plaques, the median number of segments with plaque per patient was one. Echocardiography was normal in 4/22 patients based on normal global longitudinal strain (GLS) and normal wall motion score index (WMSI) 4/22 patients had normal GLS with pathological WMSI; 3/22 patients had pathological GLS and normal WMSI; 11/22 patients had pathological GLS and WMSI and among them we could identify 5 patients with a Takotsubo pattern on echo.ConclusionsDespite a diagnosis of AMI, 80 of patients with normal ICA showed no coronary plaques on CTCA. The remaining 20 had only minimal non obstructive atherosclerosis. Patients fulfilling clinical criteria for AMI but with completely normal ICA need further evaluation, suggestively with magnetic resonance imaging (MRI)
Historical review of the causes of cancer.
Venue: World journal of clinical oncology

In the early 1900s, numerous seminal publications reported that high rates of cancer occurred in certain occupations. During this period, work with infectious agents produced only meager results which seemed irrelevant to humans. Then in the 1980s ground breaking evidence began to emerge that a variety of viruses also cause cancer in humans. There is now sufficient evidence of carcinogenicity in humans for human T cell lymphotrophic virus, human immunodeficiency virus, hepatitis B virus, hepatitis C virus, human papillomavirus, Epstein Barr virus, and human herpes virus 8 according to the International Agency for Research on Cancer (IARC) Many other causes of cancer have also been identified by the IARC, which include: Sunlight, tobacco, pharmaceuticals, hormones, alcohol, parasites, fungi, bacteria, salted fish, wood dust, and herbs. The World Cancer Research Fund and the American Institute for Cancer Research have determined additional causes of cancer, which include beta carotene, red meat, processed meats, low fibre diets, not breast feeding, obesity, increased adult height and sedentary lifestyles. In brief, a historical review of the discoveries of the causes of human cancer is presented with extended discussions of the difficulties encountered in identifying viral causes of cancer.
Magnetically treated water irrigation effect on turnip seed germination, seedling growth and enzymatic activities

Pre sowing magnetic field seed treatment effects on biological characteristics of vegetables and crops have been studied well. However, studies reporting irrigation with magnetically treated water are scanty. Therefore, the effect of irrigation with magnetically treated water on turnip seed germination, seedling growth and enzymatic activities was evaluated. The tap water was treated at 211 mT for 30, 45 and 60 min and used for irrigation of turnip seed and seedlings. Uniform and healthy turnip seed was sown under randomized complete block design (RCBD) The germination, emergence rate index, vigor index I and vigor index II increased up to 28.33% 11.54% 57.59% and 32.26% respectively. The growth parameters such as seedling lengths, fresh dry weights, chlorophyll content were also enhanced in response of irrigation with magnetically treated water. The seedlings irrigated with magnetically treated water showed 28.92% 11.36% and 14.76% higher protein content, alpha amylase and protease activities, respectively vs control. Results revealed that irrigation with magnetically treated water has potential to improve turnip germination, seedling growth and enzymatic activities and this study is also extendable to other vegetables and crops for the improvement of germination and growth.
We Need These Bodies, But Not Their Knowledge: Black Women in the Archival Science Professions and Their Connection to the Archives of Enslaved Black Women in the French Antilles
Venue: Libr. Trends

Despite calls for diversity and minority participation in library and information science (LIS) and archival science, these professions have seen little change in this respect over the past two decades. This paper attempts to connect the archived, enslaved black woman of the French Antilles to the contemporary black woman in the United States. The paucity of archival materials on the first group is reflective of the low incidence of the second group in today's archives profession. That is, the way in which black women of the Americas have been historically misrepresented or not represented at all can be connected to recruitment and retention problems in the archival profession. If black women are not recognized as worthwhile subjects in the archives, and presently not valued as knowers, how can they be accepted as library and archive professionals? If the archives are where origin stories are excavated, black women through the profession of archival science have a role to play in the administration and management of archival materials concerning the historical enslavement of black women. The paper will specifically discuss concepts from archival appraisal theory and highlight the ways in which power influences the collection of archival materials. Also, educational and training solutions that include black feminist thought, critical race theory, and cognitive justice are discussed.
Breaking down the invisible wall to enrich archival science and practice
Venue: 2016 IEEE International Conference on Big Data (Big Data)

This article reviews the state of archival science where basic concepts have been subject to a long stream of criticisms without satisfactory resolution of the issues identified. It establishes a ground for progress by articulating criteria for evaluating archival concepts and proposes a path forward by enriching archival science with concepts and methods from systemic functional linguistics and graph theory. Finally, it demonstrates how borrowing from these fields would satisfy the proposed criteria.
La superacion de la barbarie, la emancipacion del sujeto y la autorreflexion critica :fines del proyecto educativo en Theodor Adorno

Los fines de la educacion para la emancipacion en T. Adorno permiten comprender por que un proyecto educativo para superar la barbarie reconoce sus principios en la emancipacion del sujeto y en la autorreflexion critica. Las categorias que fundamentan esta novedosa propuesta adorniana se rastrean en Meditaciones sobre la Metafisica de Dialectica Negativa, alli se expone una nueva idea de filosofia y moral que orienta un proyecto educativo actualizado. Para entender este proyecto es necesario conocer como el caracter degenerativo de la racionalidad, segun Adorno, atraviesa la historia del pensamiento, desde el mito hasta la Ilustracion. Concretamente es lo que se ha denominado critica radical de la razon historica. Auschwitz como categoria racional y manifestacion moderna de esta critica sobre la historia, es expresion y evidencia del germen patologico de una racionalidad con caracter instrumental. Por esta razon, el frankfurtiano plantea que para superar Auschwitz un camino es la educacion. Es asi como determina que una educacion destinada a evitar todo tipo de expresion de la barbarie y orientada a la emancipacion debe estar dirigida: contra la insensibilidad, nueva comprension de la experiencia, la memoria, corporalidad, para superar el pasado; Educar para la memoria colectiva; Educar para no reprimir el dolor; Educacion como resistencia; educacion para la Ilustracion.
Quantitative Easing and Financial Stability

The massive expansion of central bank balance sheets in response to recent crises raises important questions about the effects of such "quantitative easing" policies, both their effects on financial conditions and on aggregate demand (the intended effects of the policies) and their possible collateral effects on financial stability. The present paper compares three alternative dimensions of central bank policy conventional interest rate policy, increases in the central bank's supply of safe (monetary) liabilities, and macroprudential policy (possibly implemented through discretionary changes in reserve requirements) showing in the context of a simple intertemporal general equilibrium model why they are logically independent dimensions of variation in policy, and how they jointly determine financial conditions, aggregate demand, and the severity of the risks associated with a funding crisis in the banking sector. In the proposed model, each of the three dimensions of policy can be used independently to influence aggregate demand, and in each case a more stimulative policy also increases financial stability risk. However, the policies are not equivalent, and in particular the relative magnitudes of the two kinds of effects are not the same. Quantitative easing policies increase financial stability risk (in the absence of an offsetting tightening of macroprudential policy) but they actually increase such risk less than either of the other two policies, relative to the magnitude of aggregate demand stimulus; and a combination of expansion of the central bank's balance sheet with a suitable tightening of macroprudential policy can have a net expansionary effect on aggregate demand with no increased risk to financial stability. This suggests that quantitative easing policies may be useful as an approach to aggregate demand management not only when the zero lower bound precludes further use of conventional interest rate policy, but also when it is not desirable to further reduce interest rates because of financial stability concerns.
Quantitative Easing in a Small Open Economy: An International Portfolio Balancing Approach

This paper studies the effects of quantitative easing (QE) in a small open economy dynamic stochastic general equilibrium model with international portfolio balancing. Portfolios are classified as imperfectly substitutable short term and long term subportfolios, each including domestic and foreign bonds. Unlike in standard small open economy models, both domestic and foreign bonds may be traded internationally. The model links the domestic term premium to the global term premium, and the implication of the model on the effectiveness of QE policies in reducing the domestic term premium depends crucially on the degree of substitutability between domestic and foreign bonds. The estimated model implies that QE in small open economies is expected to be much less effective on long term yields because of the high substitutability between home and foreign assets found in the data. In the model, this causes the effect on the exchange rate to be limited. The paper also shows that foreign investors' access to the domestic debt market is essential when evaluating the QE policy; ignoring foreign investors' access would mistakenly make the policy look more effective.
