Robust three-dimensional type-II Dirac semimetal state in SrAgBi

open access: yesnpj Quantum Materials, 2023
Topological semimetals such as Dirac, Weyl or nodal line semimetals are widely studied for their peculiar properties including high Fermi velocities, small effective masses and high magnetoresistance. When the Dirac cone is tilted, exotic phenomena could

Single‐molecule DNA flow‐stretch assays for high‐throughput DNA–protein interaction studies

open access: yesFEBS Open Bio, EarlyView.
We describe an optimised single‐molecule DNA flow‐stretch assay that visualises DNA–protein interactions in real time. Linear DNA fragments are tethered to a surface and stretched by buffer flow for fluorescence imaging. Using λ and φX174 DNA, this protocol enhances reproducibility and accessibility, providing a versatile approach for studying diverse ...

Research on Calculation of the IOL Tilt and Decentration Based on Surface Fitting [PDF]

open access: yesComputational and Mathematical Methods in Medicine, 2013
The tilt and decentration of intraocular lens (IOL) result in defocussing, astigmatism, and wavefront aberration after operation. The objective is to give a method to estimate the tilt and decentration of IOL more accurately. Based on AS-OCT images of twelve eyes from eight cases with subluxation lens after operation, we fitted spherical equation to ...

A predictive surface profile model for turning based on spectral analysis [PDF]

open access: yes, 2013
This article presents a predictive approach of surface topography based on the FFT analysis of surface profiles. From a set of experimental machining tests, the parameters investigated are: feed per revolution, insert nose radius, depth of cut and ...

Excitation of Surface Plasmons Using Tilted Planar-Waveguide Bragg Gratings

open access: yesIEEE Photonics Journal, 2011
We present a planar-integrated optical surface plasmon refractometer. The fabricated device operates by grating-matched coupling between a core waveguide mode and a set of hybrid plasmon-dielectric modes of a much wider integrated structure.

ATZ‐1 promotes DNA replication efficiency to maintain normal meiotic function

open access: yesFEBS Open Bio, EarlyView.
Absence of ATZ‐1 interferes with meiotic DNA replication and cell cycle function via CHK‐1. This causes downstream defects associated with DNA damage and genomic integrity. Taken together, this study suggests that ATZ‐1 influences DNA replication efficiency and cell cycle function to maintain normal meiotic function.

Optimizing photoexcitation conditions for time‐resolved X‐ray solution scattering experiments

open access: yesFEBS Open Bio, EarlyView.
Time‐resolved X‐ray solution scattering (TR‐XSS) is a powerful technique to visualize how proteins change their structure in real time after light activation. Selecting the right laser photoexcitation conditions—fluence, excitation geometry, and sample refresh rate—is critical to maximize the experimental signal while avoiding unwanted side effects ...

Enhanced terahertz pulses emission from InAs surface by femtosecond laser pulses with tilted intensity front

open access: yes, 2022
Paper CFV4It is shown that using femtosecond laser pulses with tilted intensity front allows controlling the direction of terahertz emission from InAs surface and by that way achieving significant increase in the generated ...
