Dual Topology of the Melanocortin-2 Receptor Accessory Protein (MRAP) Is Stable

open access: yesFrontiers in Endocrinology, 2016
MRAP (melanocortin 2 receptor accessory protein) facilitates trafficking of melanocortin 2 (MC2) receptors and is essential for ACTH binding and signaling. MRAP is a single transmembrane domain protein that forms antiparallel homodimers.

A topological characterization of generalized stable sets

open access: yesSocial Choice and Welfare, 2022
AbstractThe purpose of this note is to provide a topological characterization for the existence of the generalized stable set introduced by Van Deemen (Soc Choice Welf 8:255–260, 1991) as a generalization of the Von Neumann–Morgenstern stable set.

The Design and Optimization of a Wireless Power Transfer System Allowing Random Access for Multiple Loads

open access: yesEnergies, 2019
As is common in multi-load wireless power transfer (WPT) systems based on series–series compensation topology, the power received by loads and the efficiency of the process are highly sensitive to changes in the number of loads.

Hermitian Bulk  –  Non-Hermitian Boundary Correspondence

open access: yesPRX Quantum, 2023
Non-Hermitian band theory distinguishes between line gaps and point gaps. While point gaps can give rise to intrinsic non-Hermitian band topology without Hermitian counterparts, line-gapped systems can always be adiabatically deformed to a Hermitian ...

Reliability-Based Topology Optimization: An Extension of the SESO and SERA Methods for Three-Dimensional Structures

open access: yesApplied Sciences, 2022
This study takes an approach to reliability-based topology optimization (RBTO) for 3D structures by applying an expansion of smoothing evolutionary structural optimization (SESO) and sequential element rejection and admission (SERA) for three-dimensional

Rapid determination method of minimum stable topological plate thickness in topology optimization of complex hull structures

open access: yesZhongguo Jianchuan Yanjiu, 2021
ObjectivesThe design domain for the topological optimization of ship structures is usually based on two-dimensional shell elements. However, the thickness difference of the design domain affects the setting of volume fraction constraints and the ...

Distributed Detour Routing Scheme for Link Failure with Minimized Overhead in LEO Satellite Networks

open access: yesSensors, 2023
The mobility of low Earth orbit (LEO) satellites causes the LEO satellite network to experience topology changes. Topology change includes periodic topology change that occurs naturally and unpredictable topology change that occurs due to instability of ...
