A Category Theory of Communication Theory

open access: yesCoRR, 2015
A theory of how agents can come to understand a language is presented. If understanding a sentence $α$ is to associate an operator with $α$ that transforms the representational state of the agent as intended by the sender, then coming to know a language involves coming to know the operators that correspond to the meaning of any sentence.

Parametrized higher category theory [PDF]

open access: yes, 2022
We develop foundations for the category theory of $\infty$-categories parametrized by a base $\infty$-category. Our main contribution is a theory of indexed homotopy limits and colimits, which specializes to a theory of $G$-colimits for $G$ a finite ...

A category theory approach to completion-based theorem proving strategies (Abstract) [PDF]

open access: yes, 1991
In this paper we apply category theory to formalize the basic concepts of automated theorem proving. A theorem proving strategy is given by a set of inference rules and a search plan.

Solid Pseudopapillary Neoplasm of the Pancreas in Children and Adolescents: Expert Recommendations

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Solid pseudopapillary neoplasm of the pancreas (SPN) is a rare low‐grade malignant exocrine pancreatic tumor, mostly discovered during the second decade of life in females, with a very good prognosis, provided microscopically complete surgical excision is achieved.

AN ANALYSIS OF SOME ASPECTS OF COMPONENT-BASED PROGRAMMING FOR SELECTING APPROPRIATE CATEGORICAL STRUCTURES AS THEIR MODELS [PDF]

open access: yesActa Electrotechnica et Informatica, 2017
Formal methods and formal models are important tools in software engineering. Formal methods provide unambiguous meaning of programs written in some language or constructed from modules. Moreover, they provide the basic mathematical techniques necessary

Only up to isomorphism? Category Theory and the Foundations of Mathematics [PDF]

open access: yes, 2010
Does category theory provide a foundation for mathematics that is autonomous with respect to the orthodox foundation in a set theory such as ZFC? We distinguish three types of autonomy: logical, conceptual, and justificatory.

Survival After Hematopoietic Stem Cell Transplantation in Diamond–Blackfan Anemia Syndrome: The Role of Iron Overload—A Systematic Review

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT We assessed the effect of iron overload (IO) on mortality and complications following hematopoietic stem cell transplantation (HSCT) in patients with Diamond–Blackfan anemia syndrome (DBAS) in a systematic review of individual participant data and cohort data from observational studies.

Exploring Heterogeneity with Category and Cluster Analyses for Mixed Data

open access: yesStats, 2023
Precision medicine aims to overcome the traditional one-model-fits-the-whole-population approach that is unable to detect heterogeneous disease patterns and make accurate personalized predictions.

Homotopy theory with *-categories

open access: yesTheory and Applications of Categories, 2019
We construct model category structures on various types of (marked) *-categories. These structures are used to present the infinity categories of (marked) *-categories obtained by inverting (marked) unitary equivalences. We use this presentation to explicitly calculate the \infty-categorical G-fixed points and G-orbits for G-equivariant (marked ...

Pretorsion theories

open access: yes, 2021
Pretorsion theories∗ The notion of pretorsion theory is a wide extension of the classical notion of torsion theory in an abelian category. The idea is to associate, with any pair (T, F) of full replete subcategories of a category C, a corresponding ...
