A new decoding algorithm for hidden Markov models improves the prediction of the topology of all-beta membrane proteins

open access: yesBMC Bioinformatics, 2005
Background Structure prediction of membrane proteins is still a challenging computational problem. Hidden Markov models (HMM) have been successfully applied to the problem of predicting membrane protein topology.

A parallel Viterbi decoding algorithm

open access: yesConcurrency and Computation: Practice and Experience, 2001
AbstractIn this paper we express the Viterbi algorithm as a matrix–vector reduction in which multiplication is replaced by addition and addition by minimization. The resulting algorithm is then readily parallelized in a form suitable for implementation on a systolic processor array.

Tackling nonlinear price impact with linear strategies

open access: yesMathematical Finance, Volume 35, Issue 2, Page 422-440, April 2025.
Abstract Empirical studies in various contexts find that the price impact of large trades approximately follows a power law with exponent between 0.4 and 0.7. Yet, tractable formulas for the portfolios that trade off predictive trading signals, risk, and trading costs in an optimal manner are only available for quadratic costs corresponding to linear ...

Chromosome‐Level Genome and Organ‐Specific Transcriptome of Alnus glutinosa Uncover Lineage‐Specific Innovations in Root Nodule Symbiosis

open access: yesPlant, Cell &Environment, EarlyView.
ABSTRACT Alnus glutinosa is one of only three lineages within the order Fagales capable of establishing root nodule symbiosis (RNS). Although a fragmented genome assembly of A. glutinosa was previously available, its limited quality, combined with the lack of comprehensive transcriptomic resources, has constrained in‐depth comparative and functional ...

Detecting disease progression from animal movement using hidden Markov models

open access: yesJournal of Applied Ecology, Volume 63, Issue 3, March 2026.
We demonstrate how (H)HMMs can be tailored to different epidemiological scenarios and provide a template workflow for developing and selecting Hidden Markov models to infer disease status from animal movement data. Identifying infection before mortality occurs offers a valuable early‐warning tool for population managers, reduces reliance on difficult ...
