Certificate complexity and symmetry of nested canalizing functions [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2021
Boolean nested canalizing functions (NCFs) have important applications in molecular regulatory networks, engineering and computer science. In this paper, we study their certificate complexity.

Pedagogical implications of students’ misconceptions about deductive geometric proof

open access: yesActa Academica, 2012
The role of proof in school geometry has been a subject of intense debate throughout the twentieth century and that debate persists even today. This study aims to identify and analyse deductive geometric proof difficulties encountered by Bachelor of ...

On the proof complexity of Paris-harrington and off-diagonal ramsey tautologies [PDF]

open access: yes, 2016
We study the proof complexity of Paris-Harrington’s Large Ramsey Theorem for bi-colorings of graphs and of off-diagonal Ramsey’s Theorem. For Paris-Harrington, we prove a non-trivial conditional lower bound in Resolution and a non-trivial upper bound ...

Uniform Proof Complexity

open access: yesJournal of Logic and Computation, 2005
Summary: We define the notion of the uniform reduct of a propositional proof system as the set of those bounded formulas in the language of Peano Arithmetic which have polynomial size proofs under the Paris-Wilkie-translation. With respect to the arithmetic complexity of uniform reducts, we show that uniform reducts are \(\Pi_1^0\)-hard and obviously ...

On paths-based criteria for polynomial time complexity in proof-nets [PDF]

open access: yes, 2013
Girard's Light linear logic (LLL) characterized polynomial time in the proof-as-program paradigm with a bound on cut elimination. This logic relied on a stratification principle and a "one-door" principle which were generalized later respectively in the ...

A Fuzzy Grammar for Evaluating Universality and Complexity in Natural Language

open access: yesMathematics, 2022
The paper focuses on linguistic complexity and language universals, which are two important and controversial issues in language research. A Fuzzy Property Grammar for determining the degree of universality and complexity of a natural language is ...

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system

open access: yesFEBS Letters, EarlyView.
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

How to Prove Work: With Time or Memory

open access: yesIEEE Access, 2022
Proposed by Dwork and Naor (Crypto’ 92) as an anti-spam technique, proof-of-work is attracting more attention with the boom of cryptocurrencies. A proof-of-work scheme involves two types of participants, $\textit {i.e.}$ , provers and verifiers ...

Transcriptional network analysis of PTEN‐protein‐deficient prostate tumors reveals robust stromal reprogramming and signs of senescent paracrine communication

open access: yesMolecular Oncology, EarlyView.
Combining PTEN protein assessment and transcriptomic profiling of prostate tumors, we uncovered a network enriched in senescence and extracellular matrix (ECM) programs associated with PTEN loss and conserved in a mouse model. We show that PTEN‐deficient cells trigger paracrine remodeling of the surrounding stroma and this information could help ...
