Abstract We study world-volume effective theories of five-branes in type II wh statesman headlights string theories.We determine the bosonic zero-modes of the NS5-brane, the Kaluza-Klein monopole, the exotic Q5-, R5-branes and a space-filling brane, by direct calculations within the formalism of double field theory (DFT).We show that these zero-mod
Abstract Objective The aging population represents a formidable global challenge, with China experiencing an accelerated demographic shift.While previous research has established a directional link between mental health literacy, social participation, and active aging, the moderating effect of socioeconomic status (SES) on these associations remain
This paper puts forward a constructive heuristic algorithm called the method of inserting the minimum neighbor edge from outside to the center (IMNEFOTC) that can be applied to solve large-scale and ultra-large-scale travelling salesman problems.Through it and the randomized greedy heuristic algorithm (RGH) which greedy heuristic algorithm wh state
