PURPOSE To determine how cycling with a variable (triathlon-specific) power distribution affects subsequent running performance and quantify relationships between an individual cycling power profile and running ability after cycling. METHODS Twelve well-trained male triathletes (VO2peak 4.9 ± 0.5 L/min; mass 73.5 ± 7.7 kg; mean ± SD) undertook a cycle VO2peak and maximal aerobic power (MAP) t...

This paper discusses summary measures for the speed of adjustment in possibly cointegrated Vector Autoregressive Processes (VAR). In particular we propose long-run half-lives, based on interim and total multipliers. We discuss their relation with Granger-noncausality and other types of half-life, which are shown to convey different information, except in the univariate AR(1) case. We present li...

We decompose financial return series via wavelets into different time scales to analyse their information content regarding the volatility of the returns. Moreover, we investigate the information of each scale and discuss the decomposition of daily Value-at-Risk (VaR) forecasts. By an extensive empirical analysis, we analyse financial assets in calm and turmoil market times and show that daily ...

This study estimates three hypotheses of OPEC behavior: market-sharing, target revenue and competitive model for the period 1980 to 2000 for all OPEC courtiers except Iraq. To examine co-integration relation for oil production, we use ADF test in OLS estimation. Also we use ARDL approach to examine these hypotheses and the long run relationship of them. Results indicate none of three hypotheses...

Members of the Plasmodium falciparum var gene family encode clonally variant adhesins, which play an important role in the pathogenicity of tropical malaria. Here we employ a selective panning protocol to generate isogenic P.falciparum populations with defined adhesive phenotypes for CD36, ICAM-1 and CSA, expressing single and distinct var gene variants. This technique has established the frame...

In this study we analyze exchange rate shocks in China on its macroeconomic variables by apply TVP-VAR modeling approach. Three-dimensional impulse response functions reveal that GDP, CPI and interest are affected the short run long run. Our findings have important policy implications for Chinese government conducting policy.

Preimplantation genetic diagnosis (PGD) is now considered routine in IVF laboratories with micromanipulation capability and access to genetic diagnostic services. The past two decades have witnessed a dramatic increase in the use of PGD, the number of cycles performed, and the indications for which PGD has been used. This increase has been mirrored by a slow, but steady, increase in the range o...

achieving an acceptable level of price growth is one of the main objectives of economic policies. with consideration to the importance of food, information on food price response to monetary policies is important. to achieve the object, scholars recently emphasize the use of models in which a wide range of economic data are included. these models are created by inclusion of one or more factors ...
