Spatially-Coupled MacKay-Neal Codes and Hsu-Anastasopoulos Codes

, 2011
Kudekar et al. recently proved that for transmission over the binary erasure channel (BEC), spatial coupling of LDPC codes increases the BP threshold of the coupled ensemble to the MAP threshold of the underlying LDPC codes.

Targeted blood proteome profiling using NULISAseq identifies a high‐performance biomarker panel for Aβ pathology quantification and staging

Alzheimer's &Dementia, Volume 22, Issue 2, February 2026.
Abstract INTRODUCTION While current blood‐based biomarkers for Alzheimer's disease (AD) are effective for determining amyloid beta (Aβ) pathology positivity/negativity, they are insufficient for quantifying Aβ plaque deposition. METHODS We profiled 325 plasma proteins in a Hong Kong Chinese cohort using the Nucleic Acid Linked Immuno‑Sandwich Assay ...

Promoting Electrochemical Reactions with Dual‐Atom Catalysts for High‐Rate Lithium–Sulfur Batteries

Advanced Materials, Volume 38, Issue 2, 8 January 2026.
A scalable strategy for synthesizing transition metal–bismuth atomic pairs on carbon nitride to accelerate sulfur redox reactions in lithium–sulfur batteries is presented. Nickel‐bismuth and cobatl‐bismuth catalysts improve rate performance by promoting direct electrochemical transitions and rapid Li2S nucleation, minimizing sulfur loss, and enhancing ...

Contact equations, Lipschitz extensions and isoperimetric inequalities

, 2009
We characterize locally Lipschitz mappings and existence of Lipschitz extensions through a first order nonlinear system of PDEs. We extend this study to graded group-valued Lipschitz mappings defined on compact Riemannian manifolds.

A Scalable and Integrated Reconfigurable Intelligent Surface

Advanced Electronic Materials, Volume 12, Issue 1, 7 January 2026.
A scalable X‐band reconfigurable intelligent surface is presented using one‐bit phase‐tunable unit cells with integrated FPGA control. The RIS supports fast, high‐speed reconfiguration through WiFi, LAN, and USB interfaces and can be scaled to multiple tiles. The design achieves over 20 dBi broadside gain and reliable 2D beam steering in both elevation
