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)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)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 , Article)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 ... -
Atmospheric Corrosion Behavior of Al 6xxx Alloys in Qatar State
( Hamad bin Khalifa University Press (HBKU Press) , 2016 , Conference)Al 6000 series [Al-Mg-Si-Cu] are widely used in oil field for frames, tanks, pipelines and machinery applications. They showed a relatively high corrosion resistant, thermal and electrical conductivity and low cost. ... -
Atmospheric turbulence effect on hybrid FSO/RF systems
( IEEE Computer Society , 2017 , Conference)This article is focused on the atmospheric turbulence attenuation and their effect on the hybrid free space optical and radio frequency (FSO/RF) under Qatar harsh and dry climate. Analysis has been done by calculating the ... -
Atmospheric water harvesting by osmotic distillation and direct contact membrane distillation using hydrophobic hollow fiber membranes
( Elsevier , 2024 , Article)The use of a liquid desiccant air dehumidifier is an energy-efficient technology that can improve both indoor air temperature and humidity. However, the risk of concentrated liquid desiccant leakage into the air conditioning ... -
Atomic-scale and optical investigation of nanostructured Er disilicates in silica
( Elsevier , 2022 , Article)The optical and structural properties of Er-doped Silicon oxide based thin films elaborated by RF magnetron sputtering were investigated as a function of annealing treatment. Atom Probe Tomography and Transmission electron ... -
Atopic dermatitis: A global health perspective
( John Wiley and Sons , 2023 , Article)The International Society of AD (ISAD) organized a roundtable on global aspects of AD at the WCD 2023 in Singapore. According to the Global Burden of Disease (GBD) consortium, at least 171 million individuals were affected ...
