Coupled Chiral Optical Tamm States in Cholesteric Liquid Crystals

open access: yesPhotonics, 2018
The modes formed by two coupled chiral optical Tamm states localized at the interfaces between a photonic cholesteric liquid crystal conjugated with polarization-preserving anisotropic mirrors have been analytically and numerically investigated.

Organizing the interface—Plasma membrane architecture and receptor dynamics in virus‐cell interactions

open access: yesFEBS Letters, EarlyView.
Plasma membranes contain dynamic nanoscale domains that organize lipids and receptors. Because viruses operate at similar scales, this architecture shapes early infection steps, including attachment, receptor engagement, and entry. Using influenza A virus and HIV‐1 as examples, we highlight how receptor nanoclusters, multivalent glycan interactions ...

Deriving the normalised ion-neutral collision frequency from EISCAT observations [PDF]

open access: yesAnnales Geophysicae, 1997
Common programme observations by the EISCAT UHF radar revealed an extended interval, post geomagnetic local noon on 03 April 1992, during which the F-region ion velocity orthogonal to the geomagnetic field was significantly enhanced, to values ...

Reconstructing enzyme evolution by protein engineering

open access: yesFEBS 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 ...

Structure‐forward targeting of claudins with synthetic binders

open access: yesFEBS 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.

Physical Aspects of Radio Telegraphy [PDF]

open access: yesProceedings of the IRE, 1916
The development of radio telegraphy, as a mysterious and little understood physical art, from well known inductive and conductive methods of telegraphy is briefly stated. It is shown that radio telegraphy is now subject to engineering treatment and consists of a series of expected effects resulting from a series of controllable causes.

Engineering peptides into antibodies—opportunities and strategies for therapeutic innovation

open access: yesFEBS 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 ...

The reorganization of Pombal's Physics Museum of the University of Coimbra by Mário Augusto da Silva

open access: yesConservar Património, 2017
In 1937, the collection of scientific instruments from the Physics Cabinet of the University of Coimbra, organised in the eighteenth by João António Dalla Bella (1726-1823), was obsolete, forgotten and dispersed across several rooms of the College of ...
