The rational numbers as an abstract data type

open access: yesJournal of the ACM, 2007
We give an equational specification of the field operations on the rational numbers under initial algebra semantics using just total field operations and 12 equations. A consequence of this specification is that 0 −1 = 0, an interesting equation consistent with the ring axioms and many properties of division.

Enabling Type Checking on Columns in Data Frame Libraries by Abstract Interpretation

open access: yesIEEE Access, 2022
Data frames are a tabular data structure widely used in transforming data to an appropriate form in data analysis, especially in data wrangling. However, when data frames are implemented with libraries rather than supported at the language level, it is ...

Implementation of hyperbolic complex numbers in Julia language

open access: yesDiscrete and Continuous Models and Applied Computational Science, 2022
Hyperbolic complex numbers are used in the description of hyperbolic spaces. One of the well-known examples of such spaces is the Minkowski space, which plays a leading role in the problems of the special theory of relativity and electrodynamics. However,

Convex polyhedra with triangular faces and cone triangulation [PDF]

open access: yesYugoslav Journal of Operations Research, 2011
Considering the problem of the minimal triangulation for a given polyhedra (dividing polyhedra into tetrahedra) it is known that the cone triangulation provides the number of tetrahedra which is the smallest, or the closest to it.

CeDAR: incorporating cell type hierarchy improves cell type-specific differential analyses in bulk omics data

open access: yesGenome Biology, 2023
Bulk high-throughput omics data contain signals from a mixture of cell types. Recent developments of deconvolution methods facilitate cell type-specific inferences from bulk data.

GTM-decon: guided-topic modeling of single-cell transcriptomes enables sub-cell-type and disease-subtype deconvolution of bulk transcriptomes

open access: yesGenome Biology, 2023
Cell-type composition is an important indicator of health. We present Guided Topic Model for deconvolution (GTM-decon) to automatically infer cell-type-specific gene topic distributions from single-cell RNA-seq data for deconvolving bulk transcriptomes ...

SCADIE: simultaneous estimation of cell type proportions and cell type-specific gene expressions using SCAD-based iterative estimating procedure

open access: yesGenome Biology, 2022
A challenge in bulk gene differential expression analysis is to differentiate changes due to cell type-specific gene expression and cell type proportions.
