The Fast Hartley Transform Algorithm [PDF]
IEEE Transactions on Computers, 1987 For a given data sequence \(x_ 0,...,x_{N-1}\) the discrete Hartley transform (DHT) of order N is given by \[ Y_ k=(1/\sqrt{N})\sum^{N- 1}_{n=0}x_ n(\cos (2\pi kn/N)+\sin (2\pi kn/N)),\quad k=0,...,N-1. \] It is shown that the DHT of order N can be computed from two DHT's of order N/2, analog to the basic fact used for the fast Fourier transform (FFT).

Structural insights and therapeutic targets in Acinetobacter baumannii capsule biosynthesis
FEBS Letters, EarlyView.Hypervirulent KL49 A. baumannii's capsular polysaccharide contains the nonulosonic acid 8‐epi‐Leg5,7Ac2, synthesized by epimerization via ElaA, ElaB, and ElaC. Crystal structures of ElaA, ElaB, and ElaC reveal their role in CMP‐Leg5,7Ac2 synthesis and regioselective C8 epimerization.

Engineering peptides into antibodies—opportunities and strategies for therapeutic innovation
FEBS Letters, EarlyView.Peptides and antibodies occupy complementary therapeutic niches. Peptides recognize difficult targets in a compact format, while antibodies add specificity, long half‐life, and effector functions. This review examines strategies that merge both modalities—peptide grafting into loops, terminal and Fc fusions, and bioconjugation—highlighting how ...

Fast approximation algorithms for some maximin clustering problems [PDF]
Yugoslav Journal of Operations ResearchIn this paper, we consider three cases of an intractable problem of searching for two subsets in a finite set of points of Euclidean space. In all three cases, it is required to maximize the minimum cluster’s cardinality under constraint on each cluster ...
