A channel delay can be estimated by evaluating the channel response to a deterministic signal. In the frequency domain, a maximum likelihood delay estimator which accounts for colored Gaussian measurement noise can be formulated. A procedure that allows fast estimation of the channel delay is proposed, in case a low-pass deterministic signal is applied to the channel. Keywords—Fractional delay;...

In this paper Basel regulation is modeled in Dynamic Stochastic General Equilibrium (DSGE) framework. For this purpose, using data from 1981-2017 for Iran, capital adequacy as an importance regulation is modeled. Results show Basel regulation has procyclical effect. According to the results of the model and according to the realities of economy and banking system of Iran, in recession, lending ...

Arachidonic acid is metabolized to epoxyeicosatrienoic acids (EETs) by cytochrome (CYP) P450 epoxygenases, and to ω-terminal hydroxyeicosatetraenoic acids (HETEs) by ω-hydroxylases. EETs and HETEs often have opposite biologic effects; EETs are vasodilatory and protect against ischemia/reperfusion injury, while ω-terminal HETEs are vasoconstrictive and cause vascular dysfunction. Other oxylipins...

This paper studies the determinants and behavior of outstanding mortgage loan to value (LTV) ratios for a panel data set of 8867 Dutch households over the period 1992-2005. We find that outstanding LTVs are driven by household characteristics, life-cycle effects and mortgage type characteristics. LTV declines with the time elapsed since mortgage commencement, but this decline is faster for soca...

The effects of atrial natriuretic peptide (ANP) on transmural myocardial blood flow distribution and the reactive hyperemic response in the presence and absence of flow-limiting coronary stenosis were examined in chronically instrumented conscious dogs. Ten-second coronary occlusion without subsequent flow restriction resulted in marked reactive hyperemic responses (Doppler flow probes), mean f...

In this paper, a nonlinear delay population model is investigated. Choosing the delay as a bifurcation parameter, we demonstrate that Hopf bifurcation will occur when the delay exceeds a critical value. Global existence of bifurcating periodic solutions is established. Numerical simulations supporting the theoretical findings are included. Keywords—Population model; Stability; Hopf bifurcation;...

a r t i c l e i n f o Microfinance is a vital source of funding for micro-entrepreneurs in emerging markets and underdeveloped nations. The emphasis in the literature on social sanctions as a mechanism for ensuring high repayment rates may be misplaced. We propose that the construct of harmonious social relations needs to be added in order to explain repayment rates and that high repayment rate...
