Caterpillar Dualities and Regular Languages [PDF]

open access: yesSIAM Journal on Discrete Mathematics, 2013
We characterize obstruction sets in caterpillar dualities in terms of regular languages, and give a construction of the dual of a regular family of caterpillars. We show that these duals correspond to the constraint satisfaction problems definable by a monadic linear Datalog program with at most one EDB per rule.

UiO‐66 metal–organic frameworks in biomedicine: From structural tunability to bioimaging, photodiagnostics, and photodynamic cancer therapy

open access: yesFEBS Open Bio, EarlyView.
UiO‐66(Zr) metal–organic frameworks are chemically stable, biocompatible, and highly tunable nanomaterials. Their modular structure enables controlled drug delivery, multimodal bioimaging, and light‐activated photodynamic therapy, supporting integrated diagnostic and therapeutic (theranostic) applications in cancer and biomedical research.

Los “castella” tardorrepublicanos del noroeste murciano en el marco del paisaje comarcal del siglo I a.c.: control del territorio y romanización en el sureste peninsular

open access: yesZephyrus, 2010
Los castella romanos documentados en las cuencas del Argos y el Quípar (Caravaca de la Cruz, Murcia) se enmarcan en el contexto que define los conflictos civiles entre César y Pompeyo durante el siglo I a.C.

Transcripts enriched in codons that trigger P‐site tRNA‐mediated mRNA decay possess stable mRNA

open access: yesFEBS Open Bio, EarlyView.
PTMD codons were first described by Mendel et al. as mediators of an mRNA decay pathway dependent on the human protein CNOT3, homologous to yeast Not5. Our findings confirm that PTMD codons destabilize transcripts; however, unlike in yeast, the human pathway specifically targets and slightly destabilizes primarily stable mRNAs.

On regular trace languages

open access: yesTheoretical Computer Science, 1987
Let A be a finite alphabet and let r be a symmetrical relation on A. Let us consider the free partially commutative monoid M(A,r) generated by A with respect to r (i.e., the quotient of A * by the congruence relation generated by (ab,ba) for all (a,b) in r).

Hyperosmotic stress‐induced redistribution of pre‐mRNA cleavage factor I subunits is associated with shifts in alternative polyadenylation

open access: yesFEBS Open Bio, EarlyView.
Hyperosmotic stress triggers the relocation of the CFIm complex from the nucleus to the cytoplasm. This shift creates a nuclear ‘stoichiometric bottleneck’, limiting CFIm availability for mRNA processing. Consequently, specific mRNAs like NUDT21 and DICER1 undergo targeted 3′UTR shortening, demonstrating how spatial protein dynamics drive rapid ...

Regular Expressions

open access: yes, 1995
) (r) is a regular expression denoting the language R. 5. Nothing else is a regular expression. Example 3 Let \Sigma = f0; 1g. 1. The regular expression 00 denotes the language f00g. 2. The regular expression (0j1) denotes all strings of 0s and 1s.

Pathways and pitfalls: a qualitative study of student experiences in biomedical science education

open access: yesFEBS Open Bio, EarlyView.
Biomedical science students from underrepresented backgrounds face barriers including financial strain, disrupted laboratory access and cultural exclusion. Peer networks provide vital support when institutional systems are difficult to navigate. To create inclusive learning environments and achieve academic success, educators should blend active, hands‐

Regular and irregular verbs of the arabic language

open access: yesRUDN Journal of Language Studies, Semiotics and Semantics, 2010
The article analyzes regular patterns of word-formation models of irregular verbs of the Arabic language. The comparison of their morphological structure shows that Arabic irregular and irregular verbs reveal the typological duality the given language.
