ALMA Survey of Orion Planck Galactic Cold Clumps (ALMASOP). I. Detection of New Hot Corinos with the ACA
(2020-07-29)
We report the detection of four new hot corino sources, G211.47-19.27S, G208.68-19.20N1, G210.49-19.79W, and G192.12-11.10, from a survey study of Planck Galactic Cold Clumps in the Orion Molecular Cloud Complex with the ...
From Momentum Amplituhedron Boundaries to Amplitude Singularities and Back
(2020-07-28)
The momentum amplituhedron is a positive geometry encoding tree-level scattering amplitudes in $\mathcal{N}=4$ super Yang-Mills directly in spinor-helicity space. In this paper we classify all boundaries of the momentum ...
Jointly optimized echo state network for short-term channel state information prediction of fading channel
(2020-07-27)
Accurately obtaining channel state information (CSI) in wireless systems is significant but challenging. This paper focuses the technique of machine-learning-based channel estimation. In particular, a jointly optimized ...
The relationship between Europeanisation and policy styles: a study of agricultural and public health policymaking in three EU Member States
(2020-07-27)
The role of policy styles in policymaking has attracted renewed scholarly interestin recent years. One of the central debates in this literature revolves around thequestion of how to reconcile archetype national policy ...
Energy Efficient Relay Selection Algorithm for Virtual MIMO Cooperative Networks
(Institute of Electrical and Electronics Engineers (IEEE), 2020-07-27)
In this paper, we propose a distance based energy efficient multiple relay selection algorithm for cooperative virtual Multiple-Input-Multiple-Output (MIMO). The fundamentals of this method is to forward the source signal ...
Robust Statistics Evidence Based Secure Cooperative Spectrum Sensing for Cognitive Radio Networks
(Institute of Electrical and Electronics Engineers (IEEE), 2020-07-27)
Cognitive radio networks (CRNs), an assemble of smart schemes intended for permitting secondary users (SUs) to opportunistically access spectral bands vacant by primary user (PU), has been deliberated as a solution to ...
Are mega-events a solution to address physical inactivity? Interrogating the London 2012 Paralympic sport participation legacies among people with disabilities
(2020-07-25)
Understanding why non-active people with disabilities have not participated in more sport since the London 2012 Paralympic Games is the focus of this paper. This research reviews the constraints preventing people with ...
The impact of unresolved magnetic spots on high precision radial velocity measurements
(2020-07-23)
The Doppler method of exoplanet detection has been extremely successful, but suffers from contaminating noise from stellar activity. In this work a model of a rotating star with a magnetic field based on the geometry of ...
Exploring sustainable urbanism in masterplanned developments: : a collective case study of slippage between principles, policies, and practices
(2020-07-22)
This article is concerned with masterplan implementation and with exploring, via recourse to case studies, slippages between masterplanning principles, policies, and practices. Framed by a growing body of sustainable ...
Robust Control of Series Active Power Filters for Power Quality Enhancement in Distribution Grids: Simulation and Experimental Validation
(2020-07-22)
This paper presents a simulation study and an experimental implementation of a single-phase Series Active Power Filter (SAPF) for the mitigation of harmonics in the load voltage. The aim is to regulate the injection voltage ...
