A Social Entrepreneurship Perspective of De‐Carbonising the Footprint through Recycling Compensation: A Case Study of the NGO Madre Coraje

Corporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT This research analyses the carbon footprint of the NGO Madre Coraje, using an integrated methodology that combines the calculator provided by REAS (Red de Economía Alternativa y Solidaria) Navarra and the Life Cycle Assessment (LCA). It quantifies emissions across the three scopes of the Greenhouse Gas Protocol, evaluating both direct and ...

The Epstein-Glaser causal approach to the Light-Front QED$_{4}$. I: Free theory

, 2014
In this work we present the study of light-front field theories in the realm of axiomatic theory. It is known that when one uses the light-cone gauge pathological poles $(k^{+}) ^{-n}$ arises, demanding a prescription to be employed in order to tame ...

Natural Symmetries of the Yang-Mills Equations [PDF]

, 1994
We define a natural generalized symmetry of the Yang-Mills equations as an infinitesimal transformation of the Yang-Mills field, built in a local, gauge invariant, and Poincar\'e invariant fashion from the Yang-Mills field strength and its derivatives to

Green Human Resource Management (GHRM) and Environment Social Governance (ESG): A Systematic Literature Review

Corporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT This paper presents a systematic literature review exploring the intersection of Green Human Resource Management (GHRM) and Environmental, Social, and Governance (ESG) criteria. The study synthesizes current research, identifies prevailing trends, and highlights gaps within this emerging field.

Design-Oriented transient stability analysis of LCC-HVDC inverter with DC voltage control under grid fault

International Journal of Electrical Power & Energy Systems
Subsequent commutation failure (SCF) is an inherent issue for the line-commutated-converter based high voltage direct current (LCC-HVDC) in the receiving end.

Stability Bounds for the Generalized Kadanoff‐Baym Ansatz in the Holstein Dimer

Contributions to Plasma Physics, EarlyView.
ABSTRACT Predicting real‐time dynamics in correlated systems is demanding: exact two‐time Green's function methods are accurate but often too costly, while the Generalized Kadanoff‐Baym Ansatz (GKBA) offers time‐linear propagation at the risk of uncontrolled behavior. We examine when and why GKBA fails in a minimal yet informative setting, the Holstein

Exotic non-Abelian anyons from conventional fractional quantum Hall states [PDF]

, 2012
Non-Abelian anyons--particles whose exchange noncommutatively transforms a system's quantum state--are widely sought for the exotic fundamental physics they harbor as well as for quantum computing applications.

Strengthening urban resilience in China through underground infrastructures management: Addressing global climate challenges with technological solutions

Deep Underground Science and Engineering, EarlyView.
This paper explores how climate‐resilient technologies, such as smart grids, digital twins, and self‐healing materials, can enhance urban resilience. It highlights the urgent need for proactive planning, public‐private collaboration, and data‐driven innovation to future‐proof underground infrastructure amid accelerating climate and urban pressures ...

Enhanced constant extinction angle control for subsequent commutation failure in LCC‐HVDC

IET Generation, Transmission & Distribution
Abstract To mitigate subsequent commutation failure (SCF) in line‐commutated converter‐based high‐voltage direct current transmission systems, the response and limitations of the control system are analysed. The results reveal that due to the prolonged negative deviation of the extinction angle during recovery, the integral output of ...

Unlocking the Standard Model. I. 1 generation of quarks. Symmetries [PDF]

, 2012
A very specific two-Higgs-doublet extension of the Glashow-Salam-Weinberg model for one generation of quarks is advocated for, in which the two doublets are parity transformed of each other and both isomorphic to the Higgs doublet of the Standard Model ...
