Impact of Clean Energy on CO2 Emissions and Economic Growth within the Phases of Renewables Diffusion in Selected European Countries

open access: yesEnergies, 2021
This study explores the impact of clean energy and non-renewable energy consumption on CO2 emissions and economic growth within two phases (formative and expansion) of renewable energy diffusion for three selected countries (France, Spain, and Sweden ...

Business cycle – growth nexus: a review

open access: yesTechnological and Economic Development of Economy, 2015
Frequent reversals in business cycles pose the question whether country can achieve macroeconomic stability and/or economic growth by coordinating its economic policies. Thus, what is the role of economic policy within the short/long run in amplifying or

All-dielectric metasurfaces capable of dual-channel complex amplitude modulation

open access: yesNanophotonics, 2021
One compound metasurface with multiple functions and precise complex amplitude modulation is beneficial to photonic integration. Here, all-silicon bifunctional metasurfaces capable of independent amplitude and phase modulation in two circular polarized ...

A Calibration Method for Time Dimension and Space Dimension of Streak Tube Imaging Lidar

open access: yesApplied Sciences, 2023
Owing to the special working systems of streak tube imaging lidar (STIL), the time and space dimensions are coupled together on the streak images.

Dynamical decoupling efficiency versus quantum non-Markovianity [PDF]

open access: yes, 2015
We investigate the relationship between non-Markovianity and the effectiveness of a dynamical decoupling protocol for qubits undergoing pure dephasing.

Topological dynamical decoupling [PDF]

open access: yesScience China Physics, Mechanics & Astronomy, 2019
We show that topological equivalence classes of circles in a two-dimensional square lattice can be used to design dynamical decoupling procedures to protect qubits attached on the edges of the lattice. Based on the circles of the topologically trivial class in the original and the dual lattices, we devise a procedure which removes all kinds of local ...

What drives greenhouse gas emissions? An international scoping review of academic studies in 2010–2019

open access: yesClimate Resilience and Sustainability, 2023
Greenhouse gas (GHG) emissions have increased globally 10% in the last decade, but there is a large variation in emissions trajectories by country. Understanding the main drivers of recent changes in GHG emissions is important to guide effective climate ...

The analysis of proposals of the Common Agricultural Policy reform and its impacts for the EU

open access: yesAgricultural Economics (AGRICECON), 2003
The Common Agricultural Policy (CAP) is of the character of a highly protective policy of the EU Member States. It includes a number of measures distorting the market directly and influences the farmers' incomes depending on their production.

Improving Specific Absorption Rate Efficiency and Coil Robustness of Self-Decoupled Transmit/Receive Coils by Elevating Feed and Mode Conductors

open access: yesSensors, 2023
Self-decoupling technology was recently proposed for radio frequency (RF) coil array designs. Here, we propose a novel geometry to reduce the peak local specific absorption rate (SAR) and improve the robustness of the self-decoupled coil.

Universal dynamical decoupling of multiqubit states from environment [PDF]

open access: yes, 2011
We study the dynamical decoupling of multiqubit states from environment. For a system of m qubits, the nested Uhrig dynamical decoupling (NUDD) sequence can efficiently suppress generic decoherence induced by system-environment interaction to order N ...
