Elementary particles as elementary particles
Annals of Physics, 1965 Abstract The Z = 0 rule is investigated within a general field theoretic formulation. It is shown that the equivalence of a system with an elementary particle of vanishing wave function renormalization to a direct interaction theory is intimately related to the divergence of the bare mass and the consequent degeneration of the equations of motion ...

On Colimits and Elementary Embeddings [PDF]
The Journal of Symbolic Logic, 2013 AbstractWe give a sharper version of a theorem of Rosický, Trnková and Adámek [13], and a new proof of a theorem of Rosický [12], both about colimits in categories of structures. Unlike the original proofs, which use category-theoretic methods, we use set-theoretic arguments involving elementary embeddings given by large cardinals such as α-strongly ...

Reconstructing enzyme evolution by protein engineering
FEBS Letters, EarlyView.Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...

Investigating transcription factor dynamics in health and disease using FRAP
FEBS Letters, EarlyView.FRAP analysis of GFP‐tagged transcription factors reveals how molecular mobility and target engagement change in response to drug treatment. By combining live‐cell imaging, quantitative model fitting, and statistical analysis, this approach uncovers transcription factor dynamics linked to disease mechanisms, providing a powerful framework for ...

Journal of the History of BiologyAbstractIn 1861 the physiologist Ernst Brücke (1819–1892) published “The Elementary Organisms,” calling for a major reform of the definition of the animal cell. An English translation of Brücke’s essay is presented here for the first time. In this translation the numbered footnotes 1–9 are Brücke’s own; alphabetical endnotes A–HH are my own annotations,

Elementary Moves on Triangulations [PDF]
Discrete & Computational Geometry, 2006 It is proved that a triangulation of a polyhedron can always be transformed into any other triangulation of the polyhedron by using only elementary moves. One consequence is that an additive function (valuation) defined only on simplices may always be extended to an additive function on all polyhedra.

Structure‐forward targeting of claudins with synthetic binders
FEBS Letters, EarlyView.Claudins form the paracellular barriers between epithelial and endothelial tissues at tight junctions and are targets for molecular binders with the goal of modulating barrier permeability. Claudin‐binding molecules are relevant in drug delivery or in altering claudin interactions with disease‐causing proteins.

Engineering peptides into antibodies—opportunities and strategies for therapeutic innovation
FEBS Letters, EarlyView.Peptides and antibodies occupy complementary therapeutic niches. Peptides recognize difficult targets in a compact format, while antibodies add specificity, long half‐life, and effector functions. This review examines strategies that merge both modalities—peptide grafting into loops, terminal and Fc fusions, and bioconjugation—highlighting how ...
