Insight from a Time-Varying VAR Model with Stochastic Volatility of the French Housing and Credit Markets

Through a time-varying VAR model with drifting parameters and stochastic volatilities (Cogley and Sargent, 2005, Primiceri, 2005), we explore nonlinearities on the French housing and credit markets, which give rich insights on the persistent bubble of the 2000s. While the price increase took place during a period of low shock variance, shock persistence increased during this period, as well as the elasticity relative to demography and income. Low reactivity of the housing stock to housing prices may create construction bottlenecks and explain these nonlinearities. However, even though our framework is very flexible, part of the price increase remains unexplained.
Galois Representations From Non-Torsion Points on Elliptic Curves

Working from well-known results regarding `-adic Galois representations attached to elliptic curves arising from successive preimages of the identity, we consider a natural deformation. Given a non-zero point P on a curve, we investigate the Galois action on the splitting fields of preimages of P under multiplication-by-` maps. We give a grouptheoretic structure theorem for the corresponding Galois group, and state a conjecture regarding composita of two such splitting fields.
Magnetic interpretation of the Robinson–Schensted–Knuth algorithm

Combinatorial aspects of the Robinson–Schensted–Knuth (RSK) algorithm have been discused in the context of a Heisenberg magnetic ring with N nodes, each with the spin s. Each magnetic configuration acquires a natural interpretation as a word of the length N in the alphabet of spins, consisting of n = 2s+1 letters. We demonstrate that the construction of n-tuple cover of the ring, with a separate copy for each letter of the alphabet of spins, allows for a transparent determination of maximal length of non-decreasing subwords. Moreover, it yields completeness of the RSK correspondence in classification of the irreducible basis of the Weyl duality between actions of unitary and symmetric groups in the space spanned on all magnetic configurations.
Scaling fitness optima-Studying adaptive evolution with multiple genotypes of Aspergillus nidulans

Adaptation involves the successive substitution of beneficial mutations by selection, a process known as an adaptive walk Theoretical models of adaptation have made predictions regarding the properties of adaptive walks, but we know little empirically about how adaptation differs between different genotypes faced with the same environment, knowledge that is critical to a broad understanding of natural adaptation Furthermore, as the body of theoretical knowledge continues to grow, it is becoming apparent that the conventional model systems used to study adaptation, chiefly single-celled organisms, are not well-suited for studying adaptation in spatially structured environments, and, barring yeasts, cannot be used to study the effects of sex on adaptation This thesis tackles both questions using the fungus Aspergillus mdulans, first demonstrating that the selection coefficients of mutations, but not the total number, are affected by initial adaptedness to an environment and then developing a mathematical growth model that will allow for further development of theoretical models of adaptation in spatially structured environments
Sea Clutter and Target Detection with Deep Neural Networks

In this paper, we investigate the feasibility of applying a deep learning approach to sea clutter suppression and target detection in an inhomogeneous oceanic environment. The employed method consists of deep convolutional auto-encoders (DCAEs) to filter sea clutter and a logistic regression classifier to achieve the detection of target. The sea clutter suppression processing using DCAEs automatically removes complex patterns like superimposed clutter from a target, rather than simple patterns like echoes missing at random. Compared with conventional methods for sea clutter suppression, the algorithm does not need to estimate the covariance matrix of clutter so as to have better flexibility. The results show that reliable suppression performance and higher detection accuracy can be achieved from our experiments, whose data include the measured data and simulation data.
The economic consequences of the incremental Internet disclosure: the case of French firms

This study explores the economic consequences of incremental internet disclosure (IID) of 190 French companies pertaining to SBF 250 Index during 2012. The results, obtained from a cross-sectional regression, show that the IID is a benefit because it reduces the information asymmetry, which in turn increases the liquidity of securities’ French firms. However, the IID has no impact on the cost of equity French firms.
On Influence of Vocal Fold Size to Frequencies of Induced Vibrations

The paper deals with modelling of fluid-structure interaction (FSI). Particularly it is concerned with the example of human vocal folds and their vibration under excitation by the fluid flow. The vocal folds are described as an elastic body with the assumption of small displacements and therefore the linear elasticity theory is used. The viscous incompressible fluid flow is considered. For the purpose of the numerical solution the arbitrary Lagrangian-Eulerian method is used. The whole problem is solved by the finite element method based solver. The numerical results of the influence of vocal folds dimensions are presented.
Identification of extreme weather phenomena in near real-time

This paper describes an operational system for defining weather phenomena and indices, as well as, identifying and documenting extreme weather conditions based on the hydrometeorological observations from meteorological stations. The results are published directly on the website of the Hydrological Observatory of Athens. Different techniques are implied in real time in order to identify and exclude data errors from further processing. Extreme weather phenomena, such as extreme heat, frost, intense and heavy rainfall and extreme windy conditions, are currently monitored. Moreover, bioclimatic indicators measuring the felt air temperature (heat index and wind chill) by combining more than one meteorological variable are calculated. The system provides the flexibility to define weather phenomena and indices and to apply the identification algorithm to time series stored in the hydrometeorological database.
Relationship between Teacher Views on Levels of Organizational Support - Organizational Identification and Climate of Initiative

This study aimed to identify secondary school teachers’ views on levels of organizational support, organizational identification and climate of initiative and to determine whether there were any significant differences between these views based on teachers’ demographic characteristics and whether there were significant differences between teachers’ climate of initiative levels and levels of their organizational support and organizational identification. Universe of the study conducted with relational screening model was composed of teachers (n=240) employed in Bolu province Anatolian High Schools during 2014–2015 academic year. Organizational Support, Organizational Identification and Climate of Initiative Scales were used in the study as data collection tools. According to research results, teachers were “undecided” in their organizational identification and climate of initiative levels, “agreed” with the organizational support level total scale and its instructional support and justice support sub dimensions and “partially” agreed with the administrative support dimension. While there were no significant differences in teacher views on climate of initiative, organizational support and all its sub dimensions based on gender, marital status, level of education, professional seniority, age and union membership variables, significant differences were identified on organizational identification levels based on age and level of education variables. A low level, positive meaningful relationship was identified for teachers’ climate of initiative, organizational identification and total support, support administrative and support justice levels which are organizational support sub dimensions and no significant relationships were detected with instructional support levels.
Biomolecular Mimic Circuit for an Allosterically Regulated Enzyme of Pyrimidine Biosynthetic Pathway

A general type of molecular level metabolic control that is common to all living organisms is the feedback inhibition, wherein an increase in the product of a metabolic pathway regulates an enzyme upstream in the cascade by binding to it and decreasing enzyme activity. The de novo pyrimidine biosynthetic pathway provides a specific example for the feedback inhibition. Aspartate transcarbamoylase (ATCase) catalyzes the first step in the biosynthesis of pyrimidines and one of the best understood allosteric enzymes. The structure of ATCase is roughly triangular in shape, similar to the symbol of an op-amp IC. Since most of the enzymatic properties were analogous to the properties of IC, this inspired us to mimic the enzyme (EC 2.1.3.2) with an IC (PIN μ A741CN) in our circuit design. The Michaelis-Menten model, Lineweaver-Burk equation and the equation for the non-inverting amplifier were theoretically related and used for our model. As a result, an electronic feedback circuit was designed and tested. The biomolecular mimic circuit will develop a new level of understanding of the metabolic complexity in the cell.
Fat tail phenomena in a stochastic model of stock market : the long‑range percolation approach

Using a Gibbs distribution developed in the theory of statistical physics and a long−range percolation theory, we present a new model of a stock price process for explaining the fat tail in the distribution of stock returns. We consider two types of traders, Group A and Group B : Group A traders analyze the past data on the stock market to determine their present trading positions. The way to determine their trading positions is not deterministic but obeys a Gibbs distribution with interactions between the past data and the present trading positions. On the other hand, Group B traders follow the advice reached through the long−range percolation system from the investment adviser. As the resulting stock price process, we derive a Levy process.
Effects of Pre-Release Chilling on the Flight Ability of Sterile Males of the Mediterranean Fruit Fly (Diptera: Tephritidae)

ABSTRACT The Sterile Insect Technique (SIT) is used to suppress or eradicate infestations of the Mediterranean fruit fly (medfly), Ceratitis capitata (Wiedemann). The success of the SIT depends to a large degree on the ability of sterile males to compete successfully against wild males in obtaining matings with wild females. Sterile males are chilled to allow their transfer to and subsequent storage within the aircraft used for the releases. Here, we describe the results of an experiment that investigated the effects of varying chill duration (at 3–8 °C for 2–6 h) on flight ability of sterile males derived from mass-rearing facilities in Hawaii and Guatemala. Flight ability decreased significantly, and at the same rate, with increasing chill duration for flies from both production facilities. However, for any given chill duration, the Hawaii-derived flies displayed greater flight ability than the Guatemala-derived flies. In addition, there was significant variation in flight ability among daily shipments from both facilities. Nevertheless, the present data clearly reveal that limiting chill duration promotes higher flight performance of released sterile males. Implications of our findings for Mediterranean fruit fly SIT programs are discussed.
Development and analysis of the Soil Water Infiltration Global database

Abstract. In this paper, we present and analyze a novel global database of soil infiltration measurements, the Soil Water Infiltration Global (SWIG) database. In total, 5023 infiltration curves were collected across all continents in the SWIG database. These data were either provided and quality checked by the scientists who performed the experiments or they were digitized from published articles. Data from 54 different countries were included in the database with major contributions from Iran, China, and the USA. In addition to its extensive geographical coverage, the collected infiltration curves cover research from 1976 to late 2017. Basic information on measurement location and method, soil properties, and land use was gathered along with the infiltration data, making the database valuable for the development of pedotransfer functions (PTFs) for estimating soil hydraulic properties, for the evaluation of infiltration measurement methods, and for developing and validating infiltration models. Soil textural information (clay, silt, and sand content) is available for 3842 out of 5023 infiltration measurements (∼ 76%) covering nearly all soil USDA textural classes except for the sandy clay and silt classes. Information on land use is available for 76 % of the experimental sites with agricultural land use as the dominant type (∼ 40%). We are convinced that the SWIG database will allow for a better parameterization of the infiltration process in land surface models and for testing infiltration models. All collected data and related soil characteristics are provided online in *. xlsx and *. csv formats for reference, and we add a disclaimer that the database is for public domain use only and can be copied freely by referencing it. Supplementary data are available at https://doi.org/10.1594/PANGAEA.885492 (Rahmati et al., 2018). Data quality assessment is strongly advised prior to any use of this database. Finally, we would like to encourage scientists to extend and update the SWIG database by uploading new data to it.
Meat tenderness and water holding capacity are associated with a 959 A G mutation in the MyoG gene of Chinese indigenous cattle

Myogenin (MyoG) gene has mapped at 25 to 73 cm interval on BTA 16 where several quantitative trait loci for carcass weight and marbling are located. In this study, we determined the associations between gene-specific single nucleotide polymorphisms (SNP) in MyoG gene, to investigate whether this polymorphism affected meat quality characteristics and to evaluate the allelic and genotypic frequencies of six native Chinese cattle breeds. The breeds were Jiaxian red (JXR), Luxi (LX), Nan-yang (NY), Qinchuan (QC), Xia-Nan (XN) and Xue long (XL). Our results suggested a transition of A → G at position 959 in exon 1 of the MyoG gene in cattle that caused the substitution ( 959 Serine/ 959 Cysteine). The A959G SNP was significantly associated with water holding capacity and meat tenderness (P < 0.05), while no effect of genotype on back fat thickness, rib area, loin eye height, eye muscle width and marbling was disclosed (P > 0.05). The x 2 -test revealed that the genotype distributions among the five cattle breeds (JXR, LX, NY, QC and XL) agreed with Hardy-Weinberg equilibrium (P > 0.05), although, one breed (XN) was not in Hardy-Weinberg equilibrium (P < 0.01). We concluded that, A959G SNP can be used as an efficacious genetic marker for meat quality traits in native Chinese cattle breeds but a much large number of animals are required for Marker assisted selection.
Implications of loan portfolio concentration in Cambodia

This paper explores how the composition of banks' loan portfolios affect banks operating in Cambodia. The implications of loan portfolio concentration has begun to attract attention in recent years. However, existing studies remain focus on developed or emerging countries because data in other developing countries are lacking. In this paper, we fill this gap by investigating the effects of loan portfolio concentration on Cambodian banks' return. We find that sectoral diversification is positively related to banks' returns. In addition, foreign banks and commercial banks are less affected by loan concentration than their counterparts.
Socio-Emotional Selectivity: A Preliminary Analysis of Perspectives of Adult Learners in the University of Botswana.

Grounded in the theoretical framework of socio-emotional selectivity theory (SST), this study investigated how the socio-emotional, academic and economic experiences of adult learners in the Primary Education in the University of Botswana affected their academic engagement. This was motivated by the trend of gradual enrolment decline observed by the researchers given the fact that the staff members are not trained as adult educators. The populations of the study were students of the DPE programmes of study The sample involved ten participants in year 3, ten in year 4 - five participants per each of the two bachelors of education (B Ed) degree programmes and five participants in the masters of education (M Ed) degree programme. These participants were selected through opportunistic and convenience method. The result of the study reveals varied challenges that affect learners’ pedagogical expectations and social experiences in the university programmes at both undergraduate and graduate. While they expect to acquire new skills and knowledge for improved work environment when they complete their studies, the academic environment leaves much to be desired.
Oviposition Site Choice in a Neotropical Treefrog, Dendropsophus Ebraccatus

An organism’s fitness is determined by its ability to produce viable offspring. For animals that lack post-hatching parental care, assessing and discriminating between oviposition sites may increase offspring survival. The Neotropical treefrog, Dendropsophus ebraccatus, is the only vertebrate known to be able to lay eggs both aquatically and terrestrially, and can do so in a given night. Laying eggs in water can increase hypoxia and aquatic predation, whereas desiccation and terrestrial predation increase with oviposition on land. Dendropsophus ebraccatus therefore provides a unique opportunity to measure adult reproductive choices in response to opposing costs associated with aquatic versus terrestrial reproduction. To test this, I 1) quantified aquatic predation risk in a natural setting, 2) tested whether D. ebraccatus demonstrates oviposition site discrimination in response to an aquatic egg predator, and 3) measured the relative importance of egg desiccation and aquatic predation risk on D. ebraccatus oviposition decisions. Aquatic egg predation risk is high in nature and the presence of an aquatic egg predator altered reproductive mode choices by D. ebraccatus. Not only did D. ebraccatus discriminate against pools with aquatic egg predators, but aquatic egg predation risk outweighed terrestrial egg desiccation risk, causing frogs to lay eggs out of water even in unshaded habitats where desiccation risk is high.

Experimental investigation of flat plate self-noise reduction using trailing edge serrations

This paper presents an experimental study on the noise reduction potential of sawtooth trailing edge serrations at low-to-moderate Reynolds number (1.6× 105 < Rec < 4.2× 105, based on chord). The noise radiated by flat plates with both straight and serrated trailing edges has been measured in an anechoic wind tunnel at the University of Adelaide. The trailing edge serrations were found to reduce narrowband noise levels by up to 13 dB. The straight and serrated trailing edge far-field acoustic spectra are scaled according to existing theory and compared to predictions of trailing edge noise obtained using current semi-empirical methods. In addition, velocity spectra measured in the trailing edge near wake region using hot-wire anemometry are related to the far-field noise measurements to give further insight into the serration noise reduction mechanism.
THE USE OF SOCIAL MEDIA FOR IMPROVING ENERGY CONSUMPTION AWARENESS AND EFFICIENCY : AN OVERVIEW OF EXISTING TOOLS Track : Green Information Systems

Raising consumers’ awareness of energy consumption is one of the first steps in encouraging the adoption of energy saving behaviours that result in energy efficiency. Green information systems are becoming recognised as a solution to many environmental problems although information technology (e.g. disposal of IT devices) has also been associated with causing detrimental effects on the environment. Researchers and practitioners have begun to focus on Green ICT but there is little scholarly research on the use of ICT tools such as social media from an energy efficiency context to raise consumer awareness and improve their engagement in tackling environmental issues. Therefore, the aim of this paper is to explore the use of social media and existing tools for the interaction of people on energy saving discussions and for generating awareness and engagement (which thereby leads to energy efficiency behaviour). In this paper the authors provide a state of the art review around the concept of energy awareness, models of consumer engagement, and more importantly the use of social media in the energy efficiency context. This research is based on a desk-based normative review and seeks to provide a better understanding to both scholars and practitioners involved in the use of ICT for driving energy consumer awareness and engagement for energy efficiency.
Wearing Ergonomically Designed Core Stability Shorts Improves Cognitive Control and Affect Following Acute Aerobic Exercise

This study examined whether wearing a pair of core-supporting gym shorts influenced cognitive control and mood state follows aerobic exercise in young adults. Cognitive performance and the event related P3 potential were measured. Twenty-four adults were assigned to either the core-supporting shorts group or the normal shorts group. Participants completed 30 minutes of an acute treadmill exercise involving walking and/or running at an intensity of 70% HRmax. They next performed a modified Sternberg memory task, in which participants encoded a letter array and determine if a probe letter had been presented in the preceding set of memory items. Results indicated that the core-supporting shorts group exhibited greater response accuracy and larger P3 amplitudes as compared to the normal shorts group. In addition, the core-supporting shorts group reported more pleasantness and relaxation than the normal shorts group. These results suggest that wearing the core-supporting shorts improves the cognitive control associated with working memory and induces a positive effect as well.
