The cohesive principle and the Bolzano-Weierstraß principle

open access: yesMath. Log. Q., 2010
The aim of this paper is to determine the logical and computational strength of instances of the Bolzano-Weierstraß principle (BW) and a weak variant of it. We show that BW is instance-wise equivalent to the weak König's lemma for $Σ^0_1$-trees ($Σ^0_1$-WKL).

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation

open access: yesFEBS Letters, EarlyView.
Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

THE THEORY OF NARRATIVE IN BOOK GRAPHICS ART [PDF]

open access: yesStudiul Artelor şi Culturologie: Istorie, Teorie, Practică, 2015
The principle of narrative is common not only to literature, but also to other areas and genres of creativity. Among all the genres of fine arts, book graphics is considered to be the closest to literature. In developing book graphics there are two basic

Principle-Based Approach for the De-Identification of Code-Mixed Electronic Health Records

open access: yesIEEE Access, 2022
Code-mixing is a phenomenon where at least two languages are combined in a hybrid manner in the context of a single conversation. The use of mixed language is widespread in multilingual and multicultural countries and poses significant challenges for the

The (Glg)ABCs of cyanobacteria: modelling of glycogen synthesis and functional divergence of glycogen synthases in Synechocystis sp. PCC 6803

open access: yesFEBS Letters, EarlyView.
We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.

The(?) Correspondence Principle [PDF]

open access: yes, 2013
One finds, even in texts by distinguished physicists, diverse enunciations of the correspondence principle. Typical is that quantum mechanics should agree with classical mechanics in some appropriate limit. Most commonly, the limit specified is that of

Organ‐specific redox imbalances in spinal muscular atrophy mice are partially rescued by SMN antisense oligonucleotides

open access: yesFEBS Letters, EarlyView.
We identified a systemic, progressive loss of protein S‐glutathionylation—detected by nonreducing western blotting—alongside dysregulation of glutathione‐cycle enzymes in both neuronal and peripheral tissues of Taiwanese SMA mice. These alterations were partially rescued by SMN antisense oligonucleotide therapy, revealing persistent redox imbalance as ...

Provability in Principle and Controversial Constructivistic Principles

open access: yesJournal of Philosophical Logic, 1997
New classical epistemic principles are formulated in the language of Shapiro's system of Epistemic Arithmetic. It is argued that some intrinsic plausibility can be attributed to these principles. Subsequently, the relations between these principles and variants of controversial constructivistic principles are investigated.

Calpain small subunit homodimerization is robust and calcium‐independent

open access: yesFEBS Letters, EarlyView.
Calpains dimerize via penta‐EF‐hand (PEF) domains. Using single‐molecule force spectroscopy, we measured the strength and kinetics of PEF–PEF homodimer binding. The interaction is robust, shows a transient conformational step before dissociation, and remains largely insensitive to Ca2+.
