FEBS 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 ...

Biophysical approaches for studying viral entry
FEBS Letters, EarlyView.Viruses infect all living organisms and have been responsible for major epidemics and pandemics. Their ongoing evolutionary battle with host defenses creates a constant need for improved tools to study viral behavior. Advancing methods to probe viral attachment, fusion, and genome release deepen our understanding of how infections begin and support the

Multilayer Extreme UV Optics [PDF]
, 2011 Ultrathin layered structures are known to act well as Bragg reflectors for light down to sub-nanometer wavelengths. However, the application of such structures in multi-element optics for photolithography at the wavelength of 13.5 nm has imposed ...

QUANTUM-OPTICAL VERSION OF CRAMER THEOREM [PDF]
, 1993 Cramer's theorem is formulated in the context of quantum optics. A physical meaning for the theorem is given and is illustrated by the generation of thermal noise from a pure quantum state ...

A Single-Channel Correction Method for Spectral Responsivity Differences in Detector Arrays
PhotonicsThe spectral responsivity of photodetectors exhibits significant variations across different wavelengths. Such variations can induce substantial errors when large-scale detector array modules are employed for the measurement of laser spot parameters.

Structural insights and therapeutic targets in Acinetobacter baumannii capsule biosynthesis
FEBS Letters, EarlyView.Hypervirulent KL49 A. baumannii's capsular polysaccharide contains the nonulosonic acid 8‐epi‐Leg5,7Ac2, synthesized by epimerization via ElaA, ElaB, and ElaC. Crystal structures of ElaA, ElaB, and ElaC reveal their role in CMP‐Leg5,7Ac2 synthesis and regioselective C8 epimerization.
