Complexity measures for regular expressions

Proceedings of the sixth annual ACM symposium on Theory of computing - STOC '74, 1974
Several measures of the complexity of a regular expression are defined. (Star height and number of alphabetical symbols are two of them.) Upper and lower estimates for the complexities of expressions for certain sets of paths on graphs are derived.

Addressing persistent challenges in digital image analysis of cancer tissue: resources developed from a hackathon

Molecular Oncology, EarlyView.
Large multidimensional digital images of cancer tissue are becoming prolific, but many challenges exist to automatically extract relevant information from them using computational tools. We describe publicly available resources that have been developed jointly by expert and non‐expert computational biologists working together during a virtual hackathon

Disambiguation of Regular Expressions with Backreferences via Term Rewriting

Моделирование и анализ информационных систем
In this paper we focus on regular expressions with acyclic backreferences and treat them as a semiring satisfying certain theorems of Kleene algebra. Using these theorems as term rewriting rules, we introduce an algorithm for memory disambiguation of ...

Derivatives of Approximate Regular Expressions [PDF]

arXiv, 2012
Our aim is to construct a finite automaton recognizing the set of words that are at a bounded distance from some word of a given regular language. We define new regular operators, the similarity operators, based on a generalization of the notion of distance and we introduce the family of regular expressions extended to similarity operators, that we ...

Inhibition of acyl‐CoA synthetase long‐chain isozymes decreases multiple myeloma cell proliferation and causes mitochondrial dysfunction

Molecular Oncology, EarlyView.
Triacsin C inhibition of the acyl‐CoA synthetase long chain (ACSL) family decreases multiple myeloma cell survival, proliferation, mitochondrial respiration, and membrane potential. Made with Biorender.com. Multiple myeloma (MM) is an incurable cancer of plasma cells with a 5‐year survival rate of 59%.

Regularized product expressions of higher Riemann zeta functions [PDF]

arXiv, 2005
As a generalization of [KMW], we introduce a higher Riemann zeta function for an abstract sequence. Then we explicitly determine its regularized product expression.

Regular Expressions in Practice [PDF]

, 2016
Regular expressions are not just for programmers anymore; they are supported by common software and systems used for cataloging and metadata, and allow for very powerful search and replace, even complete reformatting of library data!

MET variants with activating N‐lobe mutations identified in hereditary papillary renal cell carcinomas still require ligand stimulation

Molecular Oncology, EarlyView.
MET variants in the N‐lobe of the kinase domain, found in hereditary papillary renal cell carcinoma, require ligand stimulation to promote cell transformation, in contrast to other RTK variants. This suggests that HGF expression in the microenvironment is important for tumor growth in such patients. Their sensitivity to MET inhibitors opens the way for

Etoposide‐induced cancer cell death: roles of mitochondrial VDAC1 and calpain, and resistance mechanisms

Molecular Oncology, EarlyView.
The complex mode of action of the topoisomerase II inhibitor etoposide in triggering apoptosis involves several mechanisms: overexpression of the mitochondrial protein VDAC1, leading to its oligomerization and formation of a large channel that mediates the release of pro‐apoptotic protein; and overexpression of the apoptosis regulators p53, Bax, and ...

Containment of Nested Regular Expressions [PDF]

arXiv, 2013
Nested regular expressions (NREs) have been proposed as a powerful formalism for querying RDFS graphs, but research in a more general graph database context has been scarce, and static analysis results are currently lacking. In this paper we investigate the problem of containment of NREs, and show that it can be solved in PSPACE, i.e., the same ...
