Natural Crystal Structure for Generating Raman‐Like Orbital Angular Momentum States

open access: yesAdvanced Science, EarlyView.
This work proposes a strategy for symmetry breaking of the degenerate OAM states relying on the natural anisotropy of crystal gain, to select the handedness of the spatial spiral phase front and further tunable Raman‐like OAM states by thermal‐driven, which clarifies the contribution of intrinsic crystal property to the OAM states and opens a new route

Catch, Cut, or Block? Versatile 4‐N‐Derivatized Sialyl Glycosides for Influenza Virus Neuraminidase Detection and Purification

open access: yesAngewandte Chemie, EarlyView.
Sialyl glycosides containing 4‐N‐derivatized sialic acids synthesized by a highly efficient one‐pot two‐enzyme (OP2E) chemoenzymatic sialylation strategy have been shown to be versatile probes. They can resist sialidase cleavage, be selective substrates by influenza sialidases, or be nanomolar substrate analog‐based inhibitors and affinity ligands ...

The State of High‐Resolution Imaging of the Human Inner Ear: A Look Into the Black Box

open access: yesAdvanced Science, EarlyView.
High‐resolution imaging of the cochlea is challenged by numerous unique aspects of this organ, where sensorineural cells, crucial for hearing, are too small for conventional modalities like magnetic resonance imaging and computed tomography. This article reviews current imaging techniques, emerging technologies, and innovations aimed at improving ...

Structure and Antigenicity of Kaposi's Sarcoma‐Associated Herpesvirus Glycoprotein B

open access: yesAdvanced Science, EarlyView.
Kaposi's sarcoma‐associated herpesvirus (KSHV) causes severe cancers without effective treatments. This study presents an atomic model of KSHV's critical infection protein, gB, revealing a unique structure shared with related herpesviruses like Epstein‐Barr virus (EBV). The structural similarity highlights vulnerable targets for antibodies, guiding the

Macrophage WEE1 Directly Binds to and Phosphorylates NF‐κB p65 Subunit to Induce Inflammatory Response and Drive Atherosclerosis

open access: yesAdvanced Science, EarlyView.
The present study shows that macrophage WEE1 drives NF‐κB activation and inflammatory atherosclerosis by directly phosphorylating p65 at S536. This finding illustrates a macrophage‐specific WEE1‐p65 axis in regulating inflammatory atherosclerosis and points out new directions to broaden the clinical applications for WEE1 inhibitors in atherosclerosis ...

Demonstration of Time Delay Interferometry and Spacecraft Ranging in a Space-based Gravitational Wave Detector using the UF-LISA Interferometry Simulator [PDF]

open access: yes, 2012
Space-based gravitational-wave observatories such as the Laser Interferometer Space Antenna (LISA) use time-shifted and time-scaled linear combinations of differential laser-phase beat signals to cancel the otherwise overwhelming laser frequency noise.

Sub-Heisenberg estimation strategies are ineffective

open access: yes, 2012
In interferometry, sub-Heisenberg strategies claim to achieve a phase estimation error smaller than the inverse of the mean number of photons employed (Heisenberg bound).

Processing Ultrasonic Data by Coda Wave Interferometry to Monitor Load Tests of Concrete Beams

open access: yesItalian National Conference on Sensors, 2018
Ultrasonic transmission measurements have been used for decades to monitor concrete elements, mostly on a laboratory scale. Recently, coda wave interferometry (CWI), a technique adapted from seismology, was introduced to civil engineering experiments. It
