Optical Fiber Meta‐Tips Based on Partial‐Phase Control

open access: yesAdvanced Optical Materials, EarlyView.
Optical fibers working as beam splitters or focusing lens are demonstrated, with the aid of a metasurface integrated on the fiber end facet. Metasurfaces based on meta‐atoms featuring partial control of the phase are considered unleashing their potential.

Validation of the Exoplanet Kepler-21b using PAVO/CHARA Long-Baseline Interferometry [PDF]

open access: yes, 2012
We present long-baseline interferometry of the Kepler exoplanet host star HD179070 (Kepler-21) using the PAVO beam combiner at the CHARA Array. The visibility data are consistent with a single star and exclude stellar companions at separations ~1-1000 ...

Atom Interferometry with the Sr Optical Clock Transition. [PDF]

open access: yesPhysical Review Letters, 2017
We report on the realization of a matter-wave interferometer based on single-photon interaction on the ultranarrow optical clock transition of strontium atoms. We experimentally demonstrate its operation as a gravimeter and as a gravity gradiometer.

High‐Throughput Fluorescence Screening Enables Globally Consistent Identification of ABA Signaling Modulators

open access: yesAdvanced Science, EarlyView.
This paper establishes a global high‐throughput fluorescence screening (GhitFluors) platform to efficiently identify ABA signaling modulators. It effectively identifies diopyridin, a regulator with strong binding affinity to PYR1, and more than 80% inhibitory activity against HAB1, which is equivalent to ABA.

Clarification on Generalized Lau condition for X-ray interferometers based on dual phase gratings [PDF]

open access: yes, 2019
To implement dual phase grating x-ray interferometry with x-ray tubes, one needs to incorporate an absorbing source grating. In order to attain good fringe visibility, the period of a source grating should be subject to a stringent condition. In literature some authors claim that the Lau-condition in Talbot-Lau interferometry can be literally ...

Estimating the phase in ground-based interferometry: performance comparison between single-mode and multimode schemes [PDF]

open access: yes, 2010
In this paper we compare the performance of multi and single-mode interferometry for the estimation of the phase of the complex visibility. We provide a theoretical description of the interferometric signal which enables to derive the phase error in ...

An Engineered Soluble Single‐Chain TCR Engager for KRAS‐G12V Specific Tumor Immunotherapy

open access: yesAdvanced Science, EarlyView.
This study develops a dimeric T cell receptor engager protein specific for tumor KRAS‐G12V mutation. The engager proteins are capable of mediating the formation of synapse between T cell and tumor cell and demonstrate substantial tumor suppression efficacy.

Reduction of the Thermal Conductivity of Polyurethanes by Fluorination: Impact of Crystallinity, Atomic Density, and Sound Velocity

open access: yesAngewandte Chemie, EarlyView.
This study provides a rich database of structure–property relationships that will help guide future work in designing polymers with low intrinsic thermal conductivity. Fluorinated polymers are widely utilized in industry for their outstanding hydrophobicity, chemical resistance, and heat resistance. Our study provides insights that fluorinated polymers
