Covalent organic frameworks provide a structurally programmable platform for solid‐state lithium batteries. This review outlines a design framework linking structural descriptors to ion‐transport metrics. It examines mechanisms of confinement, channel architecture, and hybrid designs, addressing the reasons for the occasional failure of high intrinsic ...

From Surface to Depth: SWOT Altimetry and Glider Observations of a Cuddy in the Northeast Pacific
Abstract California Undercurrent Eddies (Cuddies) transport heat, salt, and biogeochemical properties from coastal regions to the open Northeast Pacific, but their three‐dimensional structure, lateral exchange mechanisms and complete life‐cycle are still not fully understood.

Efficient Helicopter-Satellite Communication Scheme Based on Check-Hybrid LDPC Coding
When implementing helicopter-satellite communications, periodical interruption of the received signal is a challenging problem because the communication antenna is intermittently blocked by the rotating blades of the helicopter.

Construction Method of QC-LDPC Codes with Big Girth for Fast Encoding [PDF]
The sub-matrices on both diagonals of the right half of the check matrix are unit matrices.Existence of the deterministic unit matrix not only destroys the randomness of Quasie Cyclic-Low Density Parity Check(QC-LDPC) code,it leads to a certain loss of ...

The McEliece cryptosystem is the oldest code-based cryptosystem and itis believed to resist to quantum attacks. The system was proposed in1978 by Robert McEliece. It uses irreducible binary Goppa codes, butit can be instantiated with any family of linear codes for which anefficient decoder is available.

QC-LDPC Codes Construction by Concatenating of Circulant Matrices as Block-Columns
In this paper a new low complexity method for constructing binary quasi-cyclic low-density parity-check (QC-LDPC) codes is introduced. In the proposed method, each block-column of the parity check matrix H is made by a circulant matrix in a way that the ...
