Missing genotype imputation in non‐model species using self‐organizing maps
Molecular Ecology Resources, Volume 25, Issue 3, April 2025.Abstract Current methodologies of genome‐wide single‐nucleotide polymorphism (SNP) genotyping produce large amounts of missing data that may affect statistical inference and bias the outcome of experiments. Genotype imputation is routinely used in well‐studied species to buffer the impact in downstream analysis, and several algorithms are available to ...

On LR(k)-parsers of polynomial size [PDF]
arXiv, 2015 Usually, a parser for an $LR(k)$-grammar $G$ is a deterministic pushdown transducer which produces backwards the unique rightmost derivation for a given input string $x \in L(G)$. The best known upper bound for the size of such a parser is $O(2^{|G||\Sigma|^k+k\log |\Sigma| + \log |G|})$ where $|G|$ and $|\Sigma|$ are the sizes of the grammar $G$ and ...

Wildlife Society Bulletin, Volume 49, Issue 1, March 2025.Manufacturer refurbishment of 2 solar‐powered Argos GPS transmitters deployed on greater sage‐grouse improves performance after field use more than subsequent redeployment on sage‐grouse. Latitude, topographic roughness, and season affected GPS performance.

Adaptive local surface refinement based on LR NURBS and its application to contact [PDF]
, 2017 A novel adaptive local surface refinement technique based on Locally Refined Non-Uniform Rational B-Splines (LR NURBS) is presented. LR NURBS can model complex geometries exactly and are the rational extension of LR B-splines. The local representation of the parameter space overcomes the drawback of non-existent local refinement in standard NURBS-based

Code generation using a backtracking LR parser [PDF]
, 1992 Although the parsing phase of the modern compiler has been automated in a machine independent fashion, the diversity of computer architectures inhibits automating the code generation phase.

Locus coeruleus vulnerability to tau hyperphosphorylation in a rat model
Aging Cell, Volume 24, Issue 3, March 2025.Hyperphosphorylated tau (ptau) leads to calcium overload via LTCC Cav1.2 channels (1), mitochondrial complex I deficit (2), increased mitochondrial fusion (3), which can be associated with reactive oxygen species (ROS) production. Ptau also impedes anterograde transport of distinct cargoes including mitochondria.

A Model-Driven Parser Generator, from Abstract Syntax Trees to Abstract Syntax Graphs [PDF]
arXiv, 2012 Model-based parser generators decouple language specification from language processing. The model-driven approach avoids the limitations that conventional parser generators impose on the language designer. Conventional tools require the designed language grammar to conform to the specific kind of grammar supported by the particular parser generator ...

A General LR(k) Parser Building Algorithm [PDF]
, 1973 The problem is to find an efficient algorithm that, given the productions of a context-free grammar G, will discover whether G is LR(k) for given k and if it is build an efficient parser for G . The algorithm is given in Section 8.
