A linear memory algorithm for Baum-Welch training

BMC Bioinformatics, 2005
Background: Baum-Welch training is an expectation-maximisation algorithm for training the emission and transition probabilities of hidden Markov models in a fully automated way. It can be employed as long as a training set of annotated sequences is known,

On the combinatorics of sparsification

Algorithms for Molecular Biology, 2012
Background We study the sparsification of dynamic programming based on folding algorithms of RNA structures. Sparsification is a method that improves significantly the computation of minimum free energy (mfe) RNA structures.

HECM-Plus: Hyper-Entropy Enhanced Cloud Models for Uncertainty-Aware Design Evaluation in Multi-Expert Decision Systems

Entropy
Uncertainty quantification in cloud models requires simultaneous characterization of fuzziness (via Entropy, En) and randomness (via Hyper-entropy, He), yet existing similarity measures often neglect the stochastic dispersion governed by He.

On the complete moment convergence of moving average processes generated by negatively dependent random variables under sub-linear expectations

AIMS Mathematics
The moving average processes $ X_k = \sum_{i = -\infty}^{\infty}a_{i+k}Y_{i} $ is studied, where $ \{Y_i, -\infty < i < \infty\} $ is a double infinite sequence of negatively dependent random variables under sub-linear expectations, and $ \{a_i, -\infty <

On decoding the string from interfaces in 2d conformal field theories

Journal of High Energy Physics
General solutions of a gravitational junction between two copies of a three-dimensional Einstein manifold M $$ \mathcal{M} $$ correspond to the solutions of the non-linear Nambu-Goto equation for a string in M $$ \mathcal{M} $$ .

FromChamber to Orchard: Limited Efficacy of Exogenous Salicylic Acid in Field-Grown Sweet Cherry Across Three Seasons

Agronomy
Salicylic acid (SA) is an endogenous phytohormone involved in stress signaling, yet its efficacy under commercial orchard conditions remains insufficiently tested.

Nonlinear information transmission in gold markets: evidence from cross-recurrence quantification analysis (CRQA)

Hitit Sosyal Bilimler Dergisi
The study examines whether the information transfer between speculative positions and real interest rates in the gold price formation process operates as a linear, time-independent, and unidirectional mechanism, or whether it exhibits a nonlinear ...

The ALMaQUEST Survey

Astronomy & Astrophysics
Aims. We investigate the relation between molecular gas and dust extinction on kiloparsec scales. Methods. We analysed 15 253 spaxels across 51 nearby galaxies with CO(1–0) measurements and optical spectroscopy from the ALMA-MaNGA QUEnching and STar ...

Scale dependence in remotely sensed biodiversity: Leveraging continental‐scale imaging spectroscopy from the National Ecological Observatory Network

Remote Sensing in Ecology and Conservation
Biodiversity is under threat globally, with significant implications for the ecosystem processes that underpin human well‐being. Effective conservation efforts require scalable, replicable metrics to detect and monitor changes in biodiversity. However, a
