Journal of High Energy Physics, 2012 Abstract Tree-level amplitudes of gauge theories are expressed in a basis of auxiliary amplitudes with only cubic vertices. The vertices in this formalism are explicitly factorized in color and kinematics, clarifying the color-kinematics duality in gauge theory amplitudes.

Bessel Beam Dielectrics Cutting with Femtosecond Laser in GHz-Burst Mode
Micromachines, 2023 We report, for the first time to the best of our knowledge, Bessel beam dielectrics cutting with a femtosecond laser in GHz-burst mode. The non-diffractive beam shaping is based on the use of an axicon and allows for cutting glasses up to 1 mm thickness ...

International Journal of Extreme Manufacturing, 2022 We report novel results on top-down percussion drilling in different glasses with femtosecond laser GHz-bursts. Thanks to this particular regime of light – matter interaction, combining non-linear absorption and thermal cumulative effects, we obtained ...

Journal of Applied Clinical Medical Physics, Volume 23, Issue 12, December 2022., 2022 Abstract Positron emission tomography with x‐ray computed tomography (PET/CT) is increasingly being utilized for radiation treatment planning (RTP). Accurate delivery of RT therefore depends on quality PET/CT data. This study covers quality control (QC) procedures required for PET/CT for diagnostic imaging and incremental QC required for RTP.

Normative values of visual evoked potential in adults
Indian Journal of Ophthalmology, 2021 Purpose: Visual evoked potentials (VEP) are used to determine the function of visual pathway from the optic nerve to visual cortex. Various factors may affect VEP response, viz., technical and environmental.

Characterization of the water flow regime of the rivers from the Căliman Mountains (1950-2010) based on the Pardé Coefficient. [PDF]
Riscuri şi Catastrofe, 2021 The Pardé coefficient, first introduced by Maurice Pardé in 1933, is the most famous water regime classification system in the world, and can be calculated and adapted to any river on the globe, based only on the average flow of rivers.

The Suprachiasmatic Nucleus Regulates Anxiety-Like Behavior in Mice
Frontiers in Neuroscience, 2022 Individuals suffering from mood and anxiety disorders often show significant disturbances in sleep and circadian rhythms. Animal studies indicate that circadian rhythm disruption can cause increased depressive- and anxiety-like behavior, but the ...

Scalar-graviton amplitudes [PDF]
Journal of High Energy Physics, 2019 Abstract Using the CHY-formalism and its extension to a double cover we provide covariant expressions for tree-level amplitudes with two massive scalar legs and an arbitrary number of gravitons in D dimensions. Using unitarity methods, such amplitudes are needed inputs for the computation of post-Newtonian and post-Minkowskian ...
