Identification and characterization of a gene conferring stress resistance in Escherichia coli and cyanobacteria

open access: yesFEBS Open Bio, EarlyView.
Functional screening identified PcSyn14890, a cyanobacteria‐specific protein that enhances growth and stress resistance in E. coli and Synechocystis PCC6803. Although we expected it to function as a molecular chaperone, it was unable to protect against thermal aggregation of GAPDH.

MATHEMATICS OF KIN- AND GROUP-SELECTION: FORMALLY EQUIVALENT? [PDF]

open access: yesEvolution, 2010
Evolutionary game theory is a general mathematical framework that describes the evolution of social traits. This framework forms the basis of many multilevel selection models and is also frequently used to model evolutionary dynamics on networks. Kin selection, which was initially restricted to describe social interactions between relatives, has also ...

On the use of observation equivalence in synthesis abstraction [PDF]

open access: yes, 2011
In a previous paper we introduced the notion of synthesis abstraction, which allows efficient compositional synthesis of maximally permissive supervisors for large-scale systems of composed finite-state automata.

Selective elimination of quiescent cancer cells by dequalinium chloride via ROS‐mediated ferroptosis

open access: yesFEBS Open Bio, EarlyView.
Dequalinium chloride (DQ) selectively eliminates quiescent cancer cells (QCCs) by amplifying mitochondrial ROS. QCCs exhibit elevated basal ROS and limited redox‐buffering capacity, making them vulnerable to further ROS increases. DQ‐induced ROS exceeds the tolerance threshold, triggering lipid peroxidation and ferroptosis, whereas proliferating cells ...

Theoretical Equivalence in Physics [PDF]

open access: yes, 2018
I review the philosophical literature on the question of when two physical theories are equivalent. This includes a discussion of empirical equivalence, which is often taken to be necessary, and sometimes taken to be sufficient, for theoretical ...

Characterization of the key membrane protein cytochrome Cyc2 from Ghiorsea bivora

open access: yesFEBS Open Bio, EarlyView.
This study reports the first detailed biochemical analysis of Cyc2TAG1_1, a cytochrome protein involved in microbial iron oxidation. We produced and purified this enzyme in E. coli, then measured its iron‐oxidizing efficiency, and characterized its electrical and structural properties.

On some positive embedding of P^d

open access: yesLe Matematiche, 2006
We prove that any two embeddings P^d ∼ Y → X_1 , P^d ∼ Y → X_2 ,  d ≥ 3, in two n-folds projective varieties X_1 , X_2 with normal bundle N_{Y |X_1} ∼ X_{Y |X_2} ∼ (n − d)O_{P^d} (1) are formally equivalent .Moreover, we see that Y is G2 in both X_1 and ...

Determinants of undergraduate bioscience engagement: Validating attendance barriers and classroom spatial behaviour across institutions

open access: yesFEBS Open Bio, EarlyView.
Student engagement extends beyond simple attendance. Across 891 bioscience students from three universities, attendance behaviour was associated mainly with structural influences, whereas classroom spatial behaviour reflected affective and sensory factors.

Application of Semigroup Theory in Modeling Structural Equivalence in English Sentence Patterns

open access: yesJournal of Cross-Disciplinary Sustainability Innovations
Combining semigroup theory with the formal modeling of structural equivalence in English sentences patterns is the target area of this paper. In this study, we create a semigroup representing the grammatical structures of a given sentence NP, VP, PP and
