Latching chains in K-nearest-neighbor and modular small-world networks [PDF]
Latching dynamics retrieve pattern sequences successively by neural adaption and pattern correlation. We have previously proposed a modular latching chain model in Song et al.

The condensed nearest neighbor rule using the concept of mutual nearest neighborhood (Corresp.) [PDF]
A two-stage iterative algorithm for selecting a subset of a training set of samples for use in a condensed nearest neighbor (CNN) decision rule is introduced. The proposed method uses the concept of mutual nearest neighborhood for selecting samples close

Evolutionarily divergent DUF4465 domains have a common vitamin B12‐binding function
We show that DUF4465 family proteins, widespread across bacteria from gut microbiomes, hydrothermal vents, and soil, share a common vitamin B12‐binding function. These augmented β‐jellyroll proteins bind vitamin B12 via extended loops. Our findings establish sequence‐diverse DUF4465 proteins as a widespread class of B12‐binding proteins, highlighting ...

Kinetic Reverse k-Nearest Neighbor Problem [PDF]
This paper provides the first solution to the kinetic reverse $k$-nearest neighbor (\rknn) problem in $\mathbb{R}^d$, which is defined as follows: Given a set $P$ of $n$ moving points in arbitrary but fixed dimension $d$, an integer $k$, and a query point $q\notin P$ at any time $t$, report all the points $p\in P$ for which $q$ is one of the $k ...

Approximate k-flat Nearest Neighbor Search [PDF]
Let k be a nonnegative integer. In the approximate k-flat nearest neighbor (k-ANN) problem, we are given a set P ⊂ Rd of n points in d-dimensional space and a fixed approximation factor c> 1.
