A Note on Supersymmetric WZW term in Four Dimensions [PDF]

open access: yes, 2001
We reconsider the supersymmetric Wess-Zumino-Witten (SWZW) term in four dimensions. It has been known that the manifestly supersymmetric form of the SWZW term includes derivative terms on auxiliary fields, the highest components of chiral superfields ...

Quantum mechanics of higher derivative systems and total derivative terms [PDF]

open access: yes, 1995
A general theory is presented of quantum mechanics of singular, non-autonomous, higher derivative systems. Within that general theory, $n$-th order and $m$-th order Lagrangians are shown to be quantum mechanically equivalent if their difference is a ...

Obtaining the Varshni potential function using the 2-body Kaxiras–Pandey parameters [PDF]

open access: yesJournal of the Serbian Chemical Society, 2009
A generalized version of the Varshni potential function was adopted by Kaxiras and Pandey for describing the 2-body energy portion of multi-body condensed matter.

Influence of Three-Dimensional Coral Structures on Hyperspectral Benthic Reflectance and Water-Leaving Reflectance

open access: yesApplied Sciences, 2018
Shading and inter-reflections created by the three-dimensional coral canopy structure play an important role on benthic reflectance and its propagation above the water.

Convergence of derivative expansions of the renormalization group [PDF]

open access: yes, 1999
We investigate the convergence of the derivative expansion of the exact renormalization group, by using it to compute the beta function of scalar field theory.

Synthesis, Characterization and Molecular Docking of Chloro-substituted Hydroxyxanthone Derivatives

open access: yesChemistry Journal of Moldova: General, Industrial and Ecological Chemistry, 2019
In this study, the chloro-substituted hydroxyxanthones were prepared by cyclodehydration of acid derivatives and substituted phenol in the presence of Eaton reagent, followed by halogenations step to electrophilic substitution of chlorine in a moderate ...

Development of Derivative Understanding Task Instruments to Explore Student Commognition

open access: yesJurnal Pendidikan Matematika, 2023
Instruments are tool that used to collect research data. The instrument consists of two types, namely the main and supporting instruments. In this paper, we develop the supporting instruments which are used in qualitative research such as commognitive ...

Derivative Chameleons

open access: yes, 2012
We consider generalized chameleon models where the conformal coupling between matter and gravitational geometries is not only a function of the chameleon field \phi, but also of its derivatives via higher order co-ordinate invariants.

On the Lundgren–Townsend model of turbulent fine scales [PDF]

open access: yes, 1993
The strained-spiral vortex model of turbulent fines scales given by Lundgren [Phys. Fluids 25, 2193 (1982)] is used to calculate vorticity and velocity-derivative moments for homogeneous isotropic turbulence. A specific form of the relaxing spiral vortex
