This paper investigates the asymmetric effects of monetary policy on economic growth over business cycles in Iran. Estimating the models using the Hamilton (1989) Markov-switching model and by employing the data for 1960-2012, the results well identify two regimes characterized as expansion and recession. Moreover, the results show that an expansionary monetary policy has a positive and statist...

This paper generalizes the model proposed by Misra, by considering switching between political parties. In the model proposed, the movements of members from political party B to political party C and vice versa, are considered but the net movement is considered by assuming that [Formula: see text] (a constant), which implies that the movement of members is either from party B to party C or from...

The purpose of this paper is to quantify the net unit and net profit impact of promotions for a retailer and to understand the key correlates of this impact. Using data on all promotions offered in 2003 by CVS, a leading U.S. drug retailer, the authors (a) quantify the gross promotional lift; (b) decompose this into switching, stockpiling, and incremental lift for the retailer; (c) estimate the...

There exists a significant number of domains that have frequently switched their name servers for several reasons. In this work, we delved into the analysis of name-server switching behavior and presented a novel identifier called “NS-Switching Footprint” (NSSF) that can be used to cluster domains, enabling us to detect domains with suspicious behavior. We also designed a model that represents ...

In this paper, a new bidirectional buck-boost dc-dc converter with capability of soft switching and zero input current ripple is proposed. The coupled inductor is used in the proposed converter to eliminate the input current ripple. In the proposed converter, zero voltage switching (ZVS) and zero current switching (ZCS) can be obtained for the main and auxiliary switches, respectively. In addit...

We solve the coupled mode equations governing the chalcogenide nonlinear fiber Bragg gratings (FBGs) numerically, and obtain the bistability characteristics. The characteristics of the chalcogenide nonlinear FBGs such as: switching threshold intensity, bistability interval and on-off switching ratio are studied. The effects of FBG length and its third order nonlinear refractive index on FBG cha...

The present study investigated motor expertise in interpersonal competitive ball-over-net sports in terms of a dynamical system with temporal input. In a theoretical framework, the behavior of the system is characterized by a fractal-like structure according to switching input, which changes uniquely according to the duration of input and internal parameter of the system. We investigated period...

We introduce a cocktail algorithm, a good mixture of coordinate decent, the majorization-minimization principle and the strong rule, for computing the solution paths of the elastic net penalized Cox’s proportional hazards model. The cocktail algorithm enjoys a proven convergence property. We have implemented the cocktail algorithm in an R package fastcox. Numerical examples show that cocktail i...
