Automatic Econometric Model Selection using PcGets.

Model selection is ubiquitous as we simply do not know the underlying data generating process. However, substantial criticisms are targeted at many model selection procedures. All of these criticisms can be refuted by an automatic model selection algorithms called PcGets. These algorithm is an Ox Package (see Doornik, 2001) implementing automatic general-to-specific model selection for linear regression model selections using a multi-path exploration approach: see Hendry and Krolzig (2001). This article sketches the algorithm, distinguishing between the costs of search and costs of inference. The choice of search strategy and the actual simulation performance of the algorithm are discussed and we outline the quick modeller and directions for future research.
Air Speed Measurement Standards Using Wind Tunnels

Accurate air speed measurement is essential to understand flow phenomena and practical engineering problems, such as wind turbines, air ventilation systems, air filter testers, and fan testers, etc. Standard wind tunnels can provide good testing environments for calibrating and testing industrial anemometers, which are widely used for measuring air speeds in applications to various on-site air speed measurements. Air speed standards can be established by adopting a wind tunnel. In this case, some knowledges are required, regarding measurement accuracy and uncertainty assessment. To certify an industrial anemometer, a calibration certificate is issued by an accredited laboratory, which is recognized by an accreditation organization in a country, according to the ISO/IEC 17025 guide (ISO, 2005). The national metrology institutes in every country advise the accreditation organization in recognizing the accredited laboratory by providing technical supports with the national measurement standards. Traceability is established from the national standards to the industrial standards, by transferring national measurement standards from the national metrology institutes to the accredited laboratories. If an industrial anemometer is exported to a foreign country, an international calibration certification must be issued to provide the measurement accuracy requested by a customer in the foreign country. Mutual recognition arrangement realizes the international certification procedures by harmonizing the calibration and measurement capability (CMC) of industrial countries. International key comparisons are performed to fulfill the purpose of the mutual recognition arrangement. The international key comparisons are managed by the CIPM. In case of air speed metrology, three international key comparisons have been conducted by either world-wide or regional levels, up to date. In this book chapter, a brief explanation, regarding the air speed metrology, is introduced. At first, some basics of statistical methods to calibrate an industrial anemometer are explained. After that, an air speed metrology is briefly introduced by considering the traceability chain from the national measurement standards to the industrial or working standards, based on the literature. Finally, some information, regarding the mutual recognition arrangement and the international key comparisons, will be mentioned. From this approach, it is expected that some basic knowledge of the air speed metrology can be useful in understanding how to measure the industrial anemometers with good measurement accuracy and uncertainty.
Eutrophication and vertical flux: a critical evaluation of silicate addition

Availability of dissolved silicate (DSi) can affect phytoplankton species composition and the pelagic-benthic coupling. Further, consumption of DSi is assumed to be proportional to export production and sedimentation. The effect of DSi on the vertical flux of biogenic matter was investi- gated in 4 mesocosm experiments, where all enclosures were fertilised with nitrate and phosphate (NP), while half of the enclosures were given DSi as well (NPS). Sedimentation rates were expected to increase with consumption of DSi according to the 'silicate-sedimentation' hypothesis, as a result of diatom aggregate formation and/or increased faecal pellet production form diatom-grazing cope- pods. Diatoms and faecal pellet carbon did contribute significantly more to the vertical flux in the NPS than in the NP enclosures. However, sedimentation of particulate organic carbon (POC) was still not significantly different between the NP and NPS treatments. This was due to high sedimentation rates of Phaeocystis pouchetii in the NP enclosures. The results of these experiments indicate that the relationship between DSi and daily carbon export is not necessarily as simple as suggested by the silicate-sedimentation hypothesis. Much of the uncertainties concerning the hypothesis are related to the sedimentation of P. pouchetii, as they contribute not only cell carbon but also mucilagenous matter.
LDL and HDL lipoprotein subfractions in multiple sclerosis patients with decreased insulin sensitivity

Abstract Objectives. Increased metabolic and cardiovascular morbidity has been reported in multiple sclerosis (MS) patients. Previously, we have found decreased insulin sensitivity and hyperinsulinemia in a group of newly diagnosed MS patients. We hypothesize that these features may be associated with an altered lipid profile and low, intermediate, or high density lipoprotein (LDL, IDL, HDL) subclasses accelerating atherosclerosis and thus contributing to the cardiovascular risk increase in these patients. Subjects and methods. In a group of 19 newly diagnosed untreated MS patients with previously found hyperinsulinemia and insulin resistance and a matched group of 19 healthy controls, the lipoprotein subclasses profile was determined. Polyacrylamide gel electrophoresis was used to separate and measure the LDL (large LDL and small dense LDL), HDL (large, intermediate and small), and IDL (A, B and C) subclasses with the Lipoprint© System (Quantimetrix Corporation, Redondo Beach, CA, USA). Results. No difference was found either in the conventional lipid or lipoprotein subclasses profile between the MS patients and healthy controls. We found an inverse association between the level of IDL-B with fasting insulin (r=–0.504, p=0.032), the insulin resistance estimated by homeo-static model assessment – insulin resistance (HOMA-IR) (r=–0.498, p=0.035), insulin response expressed as area under the curve (AUC; r=–0.519, p=0.027), and area above the baseline (AAB; r=–0.476, p=0.045) and positive association with insulin sensitivity estimated by insulin sensitivity index (ISI) Matsuda (r=0.470, 0.048) in MS patients, but not in healthy controls suggesting the first signs in lipoprotein subclasses profile change. Conclusions. Our data indicate that changes in lipoprotein profile and subclasses are preceded by insulin resistance and hyperinsulinemia in patients with newly diagnosed MS.
Plasminogen: a potential target gene for dietary supplements and biomarker of the early stage of obesity by fatigue mice

Background: The Early Stage of Obesity by Fatigue (ESOF) is a serious sub-health issue due to the social burden and a leading cause of other diseases even death. Accordingly, a broad range of dietary supplements have been researched and applied in an effort to treat ESOF. However, only a small number of dietary supplements have been specifically applied for gene diagnosis and the targeted gene therapy for early treatment of obesity by fatigue. Materials and Methods: In order to search the target genes for the examination in this research, GSE 038921 was downloaded from the public database, Gene Expression Omnibus, including all three samples of test and control groups. Analysis was carried out using R software packages, protein-protein interaction network, Kyoto Encyclopaedia of Genes and Genomes pathway and Gene ontology enrichment. It yielded a total of six key genes caused by limited sleep. The result was tested and verified by other data: GSE 65557 and GSE 34959. Results: Finally, one gene and one key pathway were identified: Plg; complement and coagulation cascades. Conclusions: This study suggested target gene and biological marker for treatments of ESOF by dietary supplements, providing a new perspective on the pathological process of the early phrase of ESOF.
Channels and Determinants of Foreign Bank Lending

Recent crises invigorated debate about the financial stability risks associated with different forms of foreign bank lending. Would a more decentralised model of international banking – in which a greater proportion of international banking business is carried out in the country where banks operate rather than across borders – be more desirable from a financial stability point of view? This paper sheds light on aspects of this debate by using the BIS international banking statistics to investigate the channels through which foreign banks might transmit shocks across borders and to analyse the determinants of banks’ decision whether to lend locally or cross-border. Focusing on the Asia-Pacific region, we find increasing concentration among foreign bank creditors, owing in part to the rising market share of banks headquartered within the region. Thus the region continues to be vulnerable to shocks in individual creditor countries. That said, foreign banks’ share of aggregate bank credit is low in all but a few Asia-Pacific countries. We also find that the state of the banking system in the borrower country has a significant influence on the form of foreign lending. Intermediation by foreign banks takes the form of local lending where banking systems are relatively more fragile or less developed, and cross-border lending where banking systems are relatively more stable or advanced.Full publication: Cross-Border Financial Linkages: Challenges for Monetary Policy and Financial Stability
TOPOLOGY OPTIMIZATION OF SPACE STRUCTURES USING ANT COLONY METHOD

In this article, the ant colony method is utilized for topology optimization of space structures. Strain energy of the structure is minimized while the material volume is limited to a certain amount. In other words, the stiffest possible structure is sought when certain given materials are used. In addition, a noise cleaning technique is addressed to prevent undesirable members in optimum topology. The performance of the method for topology optimization of space structures are demonstrated by three numerical examples.
DESIGN OF VARIABLE IIR DIGITAL FILTERS USING EQUAL SUBFILTERS

A new approach to design variable IIR digital filters by using a cascade of N equal individual filters of any order n is proposed in this paper. First, the approximation method for lowpass filter specifications is outlined, then the general limitations of the method are investigated and a compact formula is derived. Next, the limitations for the main canonic approximations are investigated and convenient expressions are obtained. New first- and second-order filter sections, permitting very easy tuning of the cutoff frequency, are developed and the design and tuning strategies for highpass, bandpass and bandstop filters are proposed. Finally design examples are given and the superiority of the new method compared to other known is demonstrated experimentally.
Firm Entry, In ation and the Monetary Transmission Mechanism V. Lewis and C. Poilly

This paper estimates a business cycle model with endogenous rm entry by matching impulse responses to a monetary policy shock in US data. Our VAR includes net business formation, pro ts and markups. We evaluate two channels through which entry may inuence the monetary transmission process. Through the competition e¤ect, the arrival of new entrants makes the demand for existing goods more elastic, and thus lowers desired markups and prices. Through the variety e¤ect, increased rm and product entry raises consumption utility and thereby lowers the cost of living. This implies higher markups and, through the New Keynesian Phillips Curve, lower ination. While the proposed model does a good job at matching the observed dynamics, it generates insu¢ cient volatility of markups and pro ts. Estimates of standard parameters are largely una¤ected by the introduction of rm entry. Our results lend support to the variety e¤ect; however, we nd no evidence for the competition e¤ect.

CVD-grown monolayered MoS2 as an effective photosensor operating at low-voltage

We report the fabrication of a photosensor based on as-grown single crystal monolayers of MoS2 synthesized by chemical vapor deposition (CVD). The measurements were performed using Au/Ti leads in a two terminal configuration on CVD-grown MoS2 on a SiO2/Si substrate. The device was operated in air at room temperature at low bias voltages ranging from −2 V to 2 V and its sensing capabilities were tested for two different excitation wavelengths (514.5 nm and 488 nm). The responsivity reached 1.1 mA W−1 when excited with a 514.5 nm laser at a bias of 1.5 V. This responsivity is one order of magnitude larger than that reported from photo devices fabricated using CVD-grown multilayered WS2. A rectifying-effect was observed for the optically excited current, which was four times larger in the direct polarization bias when compared to the reverse bias photocurrent. Such rectifying behavior can be attributed to the asymmetric electrode placement on the triangular MoS2 monocrystal. It is envisioned that these components could eventually be used as efficient and low cost photosensors based on CVD-grown transition metal dichalcogenide monolayers.
The Oil, Government’s Budget and Economic Growth: A Dynamic Panel Data Model for Selected Oil Exporting Economies

Recognition of economic growth determinants is one of the most important concerns for economists. In the oil exporting countries oil revenues play a significant role for the economy alongside with other economic growth determinants. This paper attempts to investigate the role of oil in selected oil-revenue dependent economies. Since oil revenue goes directly to public treasury and is expended by the government, government’s management for this revenue would be crucial in the economy. This paper utilizes a proposed index, as Government Savings over Oil Revenues (GSOR). The higher level of GSOR suggests that governments finance their expenses by non-oil revenues more than oil revenues, which is a better situation. Findings from a Dynamic Panel Data model and GMM estimation method, on 12 oil exporting economies during 1990-2013, show that GSOR has significant positive effect on real GDP growth.
The Influences of Corporate Social Responsibility on Firm Performance Measured by Balanced Scorecard: An Evidence of Hotel in Thailand's Southern Border Provinces

The study aimed to investigate the extent and level of corporate social responsibility and firm performance measured by balanced scorecard of hotels in Thailand’s Southern border provinces, and to examine the influences of corporate social responsibility and firm performance measured by balanced scorecard. Population was the hotels in the five Southern boarder provinces of Thailand. By simple random sampling, 130 hotels were used as the sample of this study. Descriptive analysis and multiple regression were used to analyze in this study. The findings indicated that corporate social responsibility in terms of consumer, fair operation, employee, and environment were at a high level, while society and community was at a moderate level. Performance measured by balanced scorecard of hotels in the five Southern boarder provinces of Thailand was at a high level. Moreover, employee, environment, and society and community responsibilities had a positive significant influence on the corporate performance, while there was a negative significant influence of hotel age on the corporate performance measured by balanced scorecard.
Random Amplified Polymorphic DNA analysis provides rapid differentiation among isolates of the fish pathogen Flavobacterium psychrophilum and among Flavobacterium species

Flavobacterium psychrophilum is the agent of cold-water disease and rainbow trout fry syndrome in salmonid fish. Originally isolated in North Amenca only, the bacterium is now also responsible for severe mortalities in many salmonid hatcheries in Europe, as well as in Japan, Chile and Tasmania. The random amplified polymorphic DNA (RAPD) technique was used to analyze the genetic diversity among a collection of 177 F. psychrophilum strains isolated from different fish species and in different geographical areas. Forty 10-mer primers were tested and 5 of them were selected for further analysis of the bacterial DNAs. The primers OPH 06, OPH 08, OPG 08, OPG 14, and OPG 16 generated several reproducible profiles during a preliminary screening of the whole collection of stralns. Based on these results, the polyrnerase chain reaction (PCR) products of a selection of 60 bacterial DNAs were submitted to slow agarose gel electrophoresis for numerical analysis of the DNA fingerprintings. No correlation occurred between the combined RAPD profiles of the primers and the geographical origin of the strains, while some profiles were clearly associated with the fish species from which the strains were isolated. Another primer, OPG 10, yielded a unique RAPD profile common to all F. psychrophilum strains whereas the 9 other valld Flavobactenum species, several of which coexist in freshwater environments and may also be isolated from fish, displayed other profiles. Thus, depending on the primer used, both the typing of F. psychrophilum strains for epidemiology studies as well as the identification of this fish pathogen and its differentiation from related bacterial species could be achieved by using RAPD.
Does living close to a vineyard increase the willingness-to-pay for organic and local wine?

This paper investigates how the residents of a French wine-producing region value the attributes of wine. We elicit the willingness-to-pay for organic/non-organic and local/nonlocal wines when providing different informations about the impacts of agricultural practices. Organic and local premiums are estimated using robust M-regressions with clustered standard errors. The analysis shows that there is a significant organic premium associated with local and non-local wines, increasing with information level and decreasing with distance between participants’ dwellings and vineyards. We also ran some policy simulations to compare the welfare effects of regulatory instruments aimed at internalizing the attributes valued by consumers in possession of information.
An Effective Approach to Streaming Video Segmentation with Sub-Optimal Low Rank Decomposition

— This paper explores how to perform powerful and proficient video division while smothering the impacts of information commotions and additionally debasements, and a viable approach is acquainted with this end. Initial, a general calculation, called problematic low-rank decay (SOLD), is proposed to seek after the low-rank portrayal for video division. Given the information framework shaped by supervoxel elements of a watched video succession, SOLD looks for a problematic arrangement by making the lattice rank unequivocally decided. Specifically, the portrayal coefficient grid with the settled rank can be disintegrated into two sub-networks of low rank, and after that we iteratively streamline them with shut frame arrangements. Additionally, we join a discriminative replication earlier into SOLD in light of the perception that little size video designs have a tendency to repeat regularly inside a similar question. Second, in light of SOLD, we introduce an effective deduction calculation to perform gushing video division in both unsupervised and intuitive situations. All the more particularly, the obliged standardized cut calculation is embraced by joining the low-rank portrayal with other low level signs and fleeting reliable imperatives for spatiotemporal division. Broad analyses on two open testing informational collections VSB100 and Seg Track propose that our approach beats other video division approaches in both exactness and effectiveness.
