Tree-level color-kinematics duality from pure spinor actions
(2023-12-14)We prove that the tree-level scattering amplitudes for (super) Yang-Mills theory in arbitrary dimensions and for M2-brane models exhibit color-kinematics (CK) duality. Our proof for Yang-Mills theory substantially simplifies ... -
Tree-level color–kinematics duality implies loop-level color–kinematics duality up to counterterms
(2023-04-01)Color–kinematics (CK) duality is a remarkable symmetry of gluon amplitudes that is the key to the double copy which links gauge theory and gravity amplitudes. Here we show that the complete Yang–Mills action itself, including ... -
Tree-level scattering amplitudes from the amplituhedron
(2017-06-07)A central problem in quantum field theory is the computation of scattering amplitudes. However, traditional methods are impractical to calculate high order phenomenologically relevant observables. Building on a few decades ... -
Trend Analysis of Bullying Victimization Prevalence in Spanish Adolescent Youth at School
(2017-06-30)BACKGROUND We analyze trends in bullying victimization prevalence in a representative sample of Spanish adolescent schoolchildren in 2006, 2010, and 2014. METHODS We distinguish between reported bullying, which is assessed ... -
TRENDS AND PROSPECTS OF DIGITAL TWIN TECHNOLOGIES: A REVIEW
(2022-12-18)The plethora of technologically developed software and digital types of machinery are widely applied for industrial production and the digitalization of building technologies. The fourth industrial revolution and the ... -
Trends and socio-economic correlates of adolescent physical fighting in 30 countries.
(2013)No recent international studies provide evidence about its prevalence, trends, or social determinants of physical fighting in adolescents. We studied cross-national epidemiologic trends over time in the occurrence of ... -
Trends in adolescents' perceived parental communication across 32 countries in Europe and North America from 2002 to 2010
(2015-04-01)Background: The quality of communication with parents is a determinant of health and well-being during adolescence, being predictive of self-esteem, self-rated health and the ability to navigate health risk behaviours. ... -
Trends in BIM-based plugins development for construction activities: a systematic review
(2022-07-05)With the emergence of vast technological advancements in the construction industry to address construction issues, BIM is foreseen as a potential utilization environment. To expand BIM performance in addressing contemporary ... -
Trends in life satisfaction in European and North-American adolescents from 2002 to 2010 in over 30 countries
(2015-04-01)Background: Life satisfaction (LS) is an indicator which is widely used for assessing the perception of a child’s feeling about his life. Methods: LS is assessed in Health Behaviour in School-aged Children via the Cantril ... -
Trends in MODIS and AERONET derived aerosol optical thickness over Northern Europe
(2019-01-04)Long-term Aqua and Terra MODIS (MODerate resolution Imaging Spectroradiometer) Collections 5.1 and 6.1 (c051 and c061, respectively) aerosol data have been combined with AERONET (AERosol RObotic NETwork) ground-based sun ... -
Trends in self-rated health in European and North-American adolescents from 2002 to 2010 in 32 countries
(2015-04-01)Background: Self-rated health (SRH) in adolescence is known to be associated with health outcomes in later life. We carried out a trend analysis on data coming from three waves of data collected in 32 countries (mostly ... -
