A RARE Algorithm for 2D DOA Estimation Based on Nested Array in Massive MIMO System
IEEE Access, 2016 In this paper, a low computational complexity rank reduce (RARE) algorithm based on 2-D nested array is proposed for direction of arrival (DOA) estimation in massive multiple-input multiple-output system.

Nested data structures in array frameworks
Journal of Physics: Conference Series, 2020 Abstract The need for nested data structures and combinatorial operations on arbitrary length lists has prevented particle physicists from adopting array-based data analysis frameworks, such as R, MATLAB, Numpy, and Pandas. These array frameworks work well for purely rectangular tables and hypercubes, but arrays of variable length arrays,

Mutually balanced nested designs
, 1991 A mutually balanced nested design of strength t is introduced. It is shown that such a nested design is equivalent to a balanced array of strength t. Some recursive constructions are given for a mutually balanced nested design of strength 2.

Advanced Science, EarlyView.PDGFA/PDGFRα signaling recruits CAFs to OSCC nests, and CAF‐OSCC contact drives tumor budding invasion. Mechanistically, heterotypic adhesion via E‐cadherin/integrin α2β1 activates YAP signaling in OSCC cells, inducing EMT. Concurrently, CAFs transfer mitochondria through TNTs, supplying ATP to fuel invasion.

Advanced Science, EarlyView.A novel epitranscriptomic mechanism in rheumatoid arthritis is uncovered: NSUN2 promotes disease via m5C‐dependent stabilization of ICMT mRNA, fueling the migration and invasion of pathogenic RA FLS. Targeting this axis with engineered nanoparticles (Ce/SAA NPs) effectively inhibits disease progression, presenting a precise therapeutic strategy ...
