Asymmetric pass through of energy commodities to US sectoral returns
( Elsevier , 2022 , Article)The influence of the international energy market on different economic aspects has increased significantly, especially after an escalation in the financialization of the energy market. Likewise following this trend, the ... -
Asymmetric responses of money demand to oil price shocks in Saudi Arabia: a non-linear ARDL approach
( Routledge , 2017 , Article)Saudi Arabia is an open oil-based economy with fixed exchange rates; therefore, it has limited monetary policy autonomy. Using non-linear autoregressive distributed lag approach, this article investigates the asymmetric ... -
Asymmetric volatility and conditional expected returns: Evidence from emerging market sectors
( Emerald Group Publishing Ltd. , 2017 , Article)Purpose: The risk-return relationship is one of the most widely investigated topics in finance, yet this relationship remains one of the most controversial topics. The purpose of this paper is to investigate the asymmetric ... -
Asymmetrical multilevel inverter topology with low total standing voltage and reduced switches count
( John Wiley and Sons Ltd , 2021 , Article)This paper presented an improved asymmetrical multilevel inverter module with reduced switches count. The basic module is capable of producing 15 level outputs with four dc sources and 10 switches. The proposed topology ... -
Asymmetrical switched inductor embedded impedance source inverters with reduced number of components
( Institute of Electrical and Electronics Engineers Inc. , 2020 , Conference Paper)Two asymmetrical embedded switched-inductor Z-source inverters (AESL-ZSI) are introduced in this paper. It divides proposed Inverters into two types; ripple input current asymmetrical embedded switched-inductor Z-source ... -
Asymptotic behaviour of contraction non-autonomous semi-flows in a Banach space: Application to first-order hyperbolic PDEs
( Elsevier Ltd , 2016 , Conference Paper)The asymptotic behaviour is studied for a class of non-autonomous infinite-dimensional non-linear dissipative systems. This is achieved by using the concept of contraction semi-flow, which is a generalization of contraction ... -
Asymptotic BER analysis of FSO with multiple receive apertures over M-distributed turbulence channels with pointing errors
( Optical Society of American (OSA) , 2014 , Article)In this paper, we consider a free-space optical (FSO) communication with multiple receive apertures over M-distributed turbulence channels with pointing errors. In particular, we consider two different combining schemes ... -
Asymptotic formulae for eigenvalues and eigenfunctions of q-Sturm-Liouville problems
( WILEY-VCH Verlag , 2011 , Article)We investigate the asymptotic behavior of the eigenvalues and the eigenfunctions of q-Sturm-Liouville eigenvalue problems. For this aim we study the asymptotic behavior of q-trigonometric functions as well as fundamental ... -
Asymptotic freedom, dimensional transmutation, and an infrared conformal fixed point for the ? -function potential in one-dimensional relativistic quantum mechanics
( American Physical Society , 2014 , Article)We consider the Schr?dinger equation for a relativistic point particle in an external one-dimensional ?-function potential. Using dimensional regularization, we investigate both bound and scattering states, and we obtain ... -
Asymptotic properties of the sample mean in adaptive stratified sequential sampling with multiple selection criteria
( Iranian Mathematical Society , 2013 , Article)We extend the method of adaptive two-stage sequen-tial sampling to include designs where there is more than one crite-ria used in deciding on the allocation of additional sampling effort. These criteria, or conditions, can ... -
Asymptotic stability of time-varying distributed parameter semi-linear systems
( IFAC , 2014 , Conference Paper)The asymptotic behaviour is studied for a class of non-linear distributed parameter time-varying dissipative systems. This is achieved by using time-varying infinite-dimensional Banach state space description. Stability ... -
Asynchronous Federated Learning-based ECG Analysis for Arrhythmia Detection
( Institute of Electrical and Electronics Engineers Inc. , 2021 , Conference Paper)With the rapid elevation of technologies such as the Internet of Things (IoT) and Artificial Intelligence (AI), the traditional cloud analytics-based approach is not suitable for a long time and secure health monitoring ... -
Asynchronous flow scheduling for green ambient assisted living communications
( Institute of Electrical and Electronics Engineers Inc. , 2015 , Article)AAL applications that support users (in particular, the elderly and patients) in staying at home are increasingly becoming popular in health care systems. Basically, these AAL applications provide personal information ... -
Asynchrony among local communities stabilises ecosystem function of metacommunities
( Blackwell Publishing Ltd , 2017 , Other)Temporal stability of ecosystem functioning increases the predictability and reliability of ecosystem services, and understanding the drivers of stability across spatial scales is important for land management and policy ... -

The athlete’s heart Part II Influencing factors on the athlete’s heart: Types of sports and age (Review)
( Akadémiai Kiadó , 2013 , Article)In our previous review characteristics of the athlete’s heart were divided into three groups: morphologic (left ventricular (LV) hypertrophy, improved coronary circulation), functional (better diastolic function) and ... -
The athlete’s heart: allometric considerations on published papers and relation to cardiovascular variables
( Springer Science and Business Media Deutschland GmbH , 2024 , Article)To evaluate the morphology of the “athlete’s heart”, left ventricular (LV) wall thickness (WT) and end-diastolic internal diameter (LVIDd) at rest were addressed in publications on skiers, rowers, swimmers, cyclists, ... -
Atmospheric Black Carbon over Qatar: Seasonal Variability and Source Apportionment
( Qatar University Press , 2021 , Poster)The earth’s atmosphere contains minute particles suspended within it. These atmospheric particles influence the earth's radiation budget through their ability to absorb and scatter radiation. Black carbon (BC) is a type ... -
