Short and Length‐Independent Group Delay Supported by Topological Edge States in Finite‐Size Su–Schrieffer–Heeger Chains

Advanced Materials Technologies, EarlyView.
This study demonstrates short, length‐independent group delay supported by topological edge states in open Su–Schrieffer–Heeger networks. Strong boundary port coupling enables an order‐of‐magnitude latency reduction compared to bulk modes, alongside robust protection against bulk disorder.

Performance of Turbo-Codes with Some Proposed Interleaver Schemes

Al-Khawarizmi Engineering Journal, 2006
This paper describes a number of new interleaving strategies based on the golden section. The new interleavers are called golden relative prime interleavers, golden interleavers, and dithered golden interleavers. The latter two approaches involve sorting

Interleaving data and effects [PDF]

Journal of Functional Programming, 2015
Abstract The study of programming with and reasoning about inductive datatypes such as lists and trees has benefited from the simple categorical principle of initial algebras. In initial algebra semantics, each inductive datatype is represented by an initial f -algebra for ...

Sub‐Diffraction and Irreversibly Tunable Imaging With Potato Starch Lenses

Advanced Optical Materials, EarlyView.
Native potato starch granules function as sustainable birefringent microlenses that enable polarization‐controlled conventional and vortex lensing via spin‐to‐orbital angular momentum conversion. They provide sub‐diffraction and spiral‐contrast imaging, support vortex‐array generation with controllable topological‐charge sign, exhibit irreversible ...

Strategy of Triple‐Gradient in Binary Pixels for Flexible Pressure Sensing with High Sensitivity and Wide‐Range Linearity

Advanced Science, EarlyView.
A flexible pressure sensor with triple‐gradient design of conductivity, modulus, and dimension in binary micro‐dome pixels is proposed. Based on precisely‐designed CNT/PDMS matrix, the device exhibits a linear sensitivity of 974.1 kPa−1 across range up to 1.8 MPa (R2 > 0.99), offering an effective strategy for potential applications in healthcare ...
