Topological gravity on surfaces with boundaries
Physics Letters B, 1990 Abstract In this letter we investigate the effects of boundaries in topological gravity. This is done by the insertion of appropriate vertex operators. We indicate how the correlation functions are determined and discuss the example of the disk.

Advanced Engineering Materials, EarlyView.CT‐based finite element simulations combined with in situ X‐ray computed tomography are used to analyze insert pull‐out in nickel‐coated polymer foams. Despite variations in material parameters, deformation consistently concentrates within a narrow annular region around the insert.

Density-guided and topology-constrained road boundary extraction from urban scene point clouds
Journal of King Saud University: Computer and Information SciencesRoad boundary extraction remains a challenging task due to the structural complexity and variability of real-world road environments. In this paper, we propose a density-guided and topology-constrained road boundary extraction method that jointly ...

Advanced Engineering Materials, EarlyView.This perspective reframes additive manufacturing for electrical machines as a qualification‐limited materials and architecture design problem. It links process–structure–property–performance relationships to magnetic, conducting, dielectric, and thermal property windows, highlighting where AM can enable segmented magnetic circuits, permanent magnet ...

Topological phase transitions of generalized Brillouin zone
Communications PhysicsIt has been known that the bulk-boundary correspondence (BBC) of the non-Hermitian skin effect is characterized by the topology of the complex eigenvalue spectra, while the topology of the wave function gives rise to Hermitian BBC with conventional ...

Cylindrical cosmological simulations with STEPS
Astronomy & AstrophysicsContext. The global topology of the Universe can affect long-range gravitational forces via boundary conditions. Detailed studies of non-trivial topologies require simulations that natively adopt such geometries. Cosmological N-body simulations typically

Memristive‐Gated RC‐Delay Synaptic Transistors for Time‐Encoded Analog in‐Memory Computing
Advanced Functional Materials, EarlyView.A Memristive‐Gated Transistor for Time‐Encoded Analog In‐Memory Computing — By exploiting the RC delay of a self‐rectifying interface‐type memristor, nonlinear I–V distortion is structurally bypassed, enabling 3‐bit nonvolatile memory, spike‐timing‐based analog encoding, and hardware‐calibrated reservoir‐computing validation within a unified device ...

Observation of momentum-gap topology of light at temporal interfaces in a time-synthetic lattice
Nature CommunicationsTopological phases have prevailed across diverse disciplines, spanning electronics, photonics, and acoustics. Hitherto, the understanding of these phases has centred on energy (frequency) bandstructures, showcasing topological boundary states at spatial ...
