Polymorphic type inference and abstract data types [PDF]

open access: yesACM Transactions on Programming Languages and Systems, 1994
Many statically typed programming languages provide an abstract data type construct, such as the module in Modula-2. However, in most of these languages, implementations of abstract data types are not first-class values. Thus, they cannot be assigned to variables, passed as function parameters, or returned as function results.

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.

The Wheel of Rational Numbers as an Abstract Data Type [PDF]

open access: yes, 2021
In an arithmetical structure one can make division a total function by defining 1/0 to be an element of the structure, or by adding a new element such as infinity ∞ or error element ⊥. A wheel is an algebra in which division is totalised by setting 1/0 =

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 ...

A catalogue of the Lonchaeidae (Diptera: Tephritoidea) and Teratomyzidae (Diptera: Opomyzoidea) of Chile

open access: yesPapéis Avulsos de Zoologia, 2022
A catalogue of the Lonchaeidae and Teratomyzidae of Chile is presented. This paper comprises two genera with five species of Lonchaeidae and two genera with two species of Teratomyzidae known from Chile, including information about the name of the taxon,

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.

PREFERABLE TYPE OF ABSTRACT IN LEADING SCIENTIFIC JOURNALS [PDF]

open access: yesTrakia Journal of Sciences, 2020
An abstract is perhaps the most important single paragraph in a manuscript since it is used for reference purposes in different scientific databases.
