Dead Center Identification of Single-DOF Multi-Loop Planar Manipulator and Linkage Based on Graph Theory and Transmission Angle [PDF]
IEEE Access, 2019 The dead center position (or singular position) is an important kinematic characteristic in mechanical design. However, its identification is a challenging task and becomes even more complex in multi-loop planar linkages (or manipulators).

Learning about Quantum Gravity with a Couple of Nodes [PDF]
Symmetry, Integrability and Geometry: Methods and Applications, 2012 Loop Quantum Gravity provides a natural truncation of the infinite degrees of freedom of gravity, obtained by studying the theory on a given finite graph. We review this procedure and we present the construction of the canonical theory on a simple graph,

Heterotic-string amplitudes at one loop: modular graph forms and relations to open strings [PDF]
Journal of High Energy Physics, 2019 We investigate one-loop four-point scattering of non-abelian gauge bosons in heterotic string theory and identify new connections with the corresponding open-string amplitude.

Supergravity limit of genus two modular graph functions in the worldline formalism
Physics Letters B, 2018 We consider the contributions up to the D10R4 terms in the low momentum expansion of the two loop four graviton amplitude in maximal supergravity that arise in the field theory limit of genus two modular graph functions that result from the low momentum ...

Nuclear Physics B, 2015 We study the expectation value of a nonplanar Wilson graph operator in SL(2,C) Chern–Simons theory on S3. In particular we analyze its asymptotic behavior in the double-scaling limit in which both the representation labels and the Chern–Simons coupling ...

A supersymmetric exotic field theory in (1+1) dimensions: one loop soliton quantum mass corrections
Journal of High Energy Physics, 2018 We consider one loop quantum corrections to soliton mass for the N = 1 $$ \mathcal{N}=1 $$ supersymmetric extension of the (1+1)-dimensional scalar field theory with the potential U (ϕ) = ϕ 2 cos2 (ln ϕ 2).

MODELING AND SIMULATION OF SINGLE LOOP PLANETARY TRANSMISSION SYSTEM BASED ON BOND GRAPH THEORY
Jixie qiangdu, 2017 Based on bond graph theory,considering the time-varying meshing stiffness,damping and tooth surface friction force of internal and external gear,using LuGre friction model,the bond graph model of NGW type planetary gear was established. And then,the bond

Self-loops in evolutionary graph theory: Friends or foes?
PLOS Computational Biology, 2023 Evolutionary dynamics in spatially structured populations has been studied for a long time. More recently, the focus has been to construct structures that amplify selection by fixing beneficial mutations with higher probability than the well-mixed population and lower probability of fixation for deleterious mutations.

A New Graphical Representation of the Old Algebraic Structure
Journal of Mathematics, 2023 The most recent advancements in algebra and graph theory enable us to ask a straightforward question: what practical use does this graph connected with a mathematical system have in the real world?
