Understanding the errors of SHAPE-directed RNA structure modeling [PDF]
, 2011 Single-nucleotide-resolution chemical mapping for structured RNA is being rapidly advanced by new chemistries, faster readouts, and coupling to computational algorithms. Recent tests have shown that selective 2'-hydroxyl acylation by primer extension (SHAPE) can give near-zero error rates (0-2%) in modeling the helices of RNA secondary structure. Here,

SIGMA 12 (2016), 066, 19 pages, 2016 We recall criteria on the spectrum of Jacobi matrices such that the corresponding isospectral torus consists of periodic operators. Motivated by those known results for Jacobi matrices, we define a new class of operators called GMP matrices. They form a certain Generalization of matrices related to the strong Moment Problem.

c-di-GMP Inhibits Early Sporulation in Clostridioides difficile
mSphere, 2021 The formation of dormant spores is essential for the anaerobic pathogen Clostridioides difficile to survive outside the host gastrointestinal tract. The regulatory pathways and environmental signals that initiate C.

Frontiers in Molecular Neuroscience, 2014 Atrial natriuretic factor receptor guanylate cyclase, ANF-RGC, was the first discovered member of the mammalian membrane guanylate cyclase family. The hallmark feature of the family is that a single protein contains both the site for recognition of the ...

Computing Tropical Prevarieties in Parallel [PDF]
arXiv, 2017 The computation of the tropical prevariety is the first step in the application of polyhedral methods to compute positive dimensional solution sets of polynomial systems. In particular, pretropisms are candidate leading exponents for the power series developments of the solutions.

DULAG: A DUal and Lensed AGN candidate catalog with GMP method [PDF]
A&A 692, A154 (2024)Context. A series of studies have demonstrated that the Gaia multipeak method (GMP) is a very efficient technique to select active galactic nucleus (AGN) pair candidates. The number of candidates is determined by the size of the input AGN catalogs, usually limited to spectroscopically-confirmed objects. Aims.

Factorization with genus 2 curves [PDF]
, 2009 The elliptic curve method (ECM) is one of the best factorization methods available. It is possible to use hyperelliptic curves instead of elliptic curves but it is in theory slower. We use special hyperelliptic curves and Kummer surfaces to reduce the complexity of the algorithm.

Identification of feasible pathway information for c-di-GMP binding proteins in cellulose production [PDF]
EMBEC & NBC 2017. EMBEC NBC 2017 2017. IFMBE Proceedings, vol 65.
Springer, Singapore, 2022 In this paper, we utilize a machine learning approach to identify the significant pathways for c-di-GMP signaling proteins. The dataset involves gene counts from 12 pathways and 5 essential c-di-GMP binding domains for 1024 bacterial genomes. Two novel approaches, Least absolute shrinkage and selection operator (Lasso) and Random forests, have been ...

Gaussian Message Passing for Overloaded Massive MIMO-NOMA [PDF]
arXiv, 2018 This paper considers a low-complexity Gaussian Message Passing (GMP) scheme for a coded massive Multiple-Input Multiple-Output (MIMO) systems with Non-Orthogonal Multiple Access (massive MIMO-NOMA), in which a base station with $N_s$ antennas serves $N_u$ sources simultaneously in the same frequency.

Tight Bounds for Uncertain Time-Correlated Errors with Gauss-Markov Structure [PDF]
arXiv, 2020 Safety-critical navigation applications require that estimation errors be reliably quantified and bounded. This can be challenging for linear dynamic systems if the process noise or measurement errors have uncertain time correlation. In many systems (e.g., in satellite-based or inertial navigation systems), there are sources of time-correlated sensor ...
