Biophysical approaches for studying viral entry

open access: yesFEBS 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

Engineering multiphoton states for linear optics computation

open access: yes, 2006
Transformations achievable by linear optical components allow to generate the whole unitary group only when restricted to the one-photon subspace of a multimode Fock space.

Electron-impact excitation of neutral boron using the R-matrix with pseudostates method [PDF]

open access: yes, 1989
We have carried out a large R-matrix with pseudostates (RMPS) calculation of the electron-impact excitation of neutral boron. The RMPS method has been employed for the excitation/ionisation of many light fusion related species, but primarily for one or ...

Structural insights and therapeutic targets in Acinetobacter baumannii capsule biosynthesis

open access: yesFEBS 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.

Harmonic generation in gases using Bessel-gauss beams [PDF]

open access: yes, 1998
The generation and propagation of harmonics in an atomic gas are described for the case of an incident Bessel-Gauss beam. Theoretical expressions are derived for the far-field amplitude of the harmonic field by solving the propagation equation using an ...

Optical Analogs of Rabi Splitting in Integrated Waveguide‐Coupled Resonators

open access: yesAdvanced Physics Research, 2023
Realizing optical analogs of quantum phenomena in atomic, molecular, or condensed matter physics has underpinned a range of photonic technologies. Rabi splitting is a quantum phenomenon induced by a strong interaction between two quantum states, and its ...

Hippo pathway at the crossroads of stemness and therapeutic resistance in breast cancer

open access: yesMolecular Oncology, EarlyView.
Dysregulation of the Hippo pathway drives nuclear accumulation of YAP/TAZ, activating stemness‐related transcriptional programs that sustain breast cancer stemness and fuel therapeutic resistance across subtypes, underscoring Hippo signaling as a targetable vulnerability. Figure created and edited with BioRender.com.

Phase-dependent transparency in a two-level system with applications to all-optical switching

open access: yesFrontiers in Quantum Science and Technology
The phenomenon of transparency, conventionally studied in three and higher level atomic systems, is extended to the case of a two-level system (TLS), where we use a semiclassical framework to describe the transparent propagation of classical fields in a ...

Enhanced detection techniques of orbital angular momentum states in the classical and quantum regimes

open access: yesNew Journal of Physics, 2021
The orbital angular momentum (OAM) of light has been at the center of several classical and quantum applications for imaging, information processing and communication.
