FEBS Letters, EarlyView.The NlpC_P60 superfamily of peptidases is recognised by its key role in bacterial cell wall homeostasis. Recently, studies have also described the involvement of NlpC_P60‐like enzymes in bacterial competitive mechanisms and pathogenesis across several lineages.

Making tau amyloid models in vitro: a crucial and underestimated challenge
FEBS Letters, EarlyView.This review highlights the challenges of producing in vitro amyloid assemblies of the tau protein. We review how accurately the existing protocols mimic tau deposits found in the brain of patients affected with tauopathies. We discuss the important properties that should be considered when forming amyloids and the benchmarks that should be used to ...

On radical and torsion theory in the category of S-acts [PDF]
arXiv, 2018 In abelian categories like the category of R-modules and even in the category S-Act 0 of S-acts with a unique zero, idempotent radicals and torsion theories are equivalent, and the {\tau}-torsion and {\tau}- torsion free classes of a torsion theory {\tau} are closed under coproducts. These are not necessarily true in the category S-Act of S-acts.

Chinese Character Recognition with Radical-Structured Stroke Trees [PDF]
arXiv, 2022 The flourishing blossom of deep learning has witnessed the rapid development of Chinese character recognition. However, it remains a great challenge that the characters for testing may have different distributions from those of the training dataset. Existing methods based on a single-level representation (character-level, radical-level, or stroke-level)

A Manifesto for Radical Children’s Literature (and an Argument Against Radical Aesthetics)
Barnboken: Tidskrift för Barnlitteraturforskning, 2019 In The Avant-Garde and American Postmodernity: Small Incisive Shocks (2002), I took for granted that an avant-garde for children was both possible and critically viable.

Quantum Zeno Effect Explains Magnetic-Sensitive Radical-Ion-Pair Reactions
, 2009 Chemical reactions involving radical-ion pairs are ubiquitous in biology, since not only are they at the basis of the photosynthetic reaction chain, but are also assumed to underlie the biochemical magnetic compass used by avian species for navigation ...

Unraveling Mycobacterium tuberculosis acid resistance and pH homeostasis mechanisms
FEBS Letters, EarlyView.Mycobacterium tuberculosis exhibits a remarkable resilience to acid stress. In this Review, we discuss some of the molecular mechanisms and metabolic pathways used by the tubercle bacilli to adapt and resist host‐mediated acid stress. Mycobacterium tuberculosis (Mtb) is a successful pathogen that has developed a variety of strategies to survive and ...

Radical Pasts, Radical Futures
, 2022 The final decades of the nineteenth century were marked by unprecedented levels of labor unrest, agitation, and organization in the United States, a period most often remembered, if at all, by way of the Great Railroad Strike of 1877 and the Homestead Steel Strike of 1892, both of which were ultimately broken by the mobilization of state, federal, or ...
