Design and modeling of corneal aberration correction with diffractive IOL based on ZEMAX

Results in Optics, 2023
This paper estimates a specific detailed diffractive aspheric bifocal intraocular lens (IOL) used to correct and reduce corneal aberration and a patient’s standard surgical implantation.

Multiple micro-optical atom traps with a spherically aberrated laser beam

, 2004
We report on the loading of atoms contained in a magneto-optic trap into multiple optical traps formed within the focused beam of a CO_{2} laser. We show that under certain circumstances it is possible to create a linear array of dipole traps with well ...

Sequence determinants of RNA G‐quadruplex unfolding by Arg‐rich regions

FEBS Letters, EarlyView.
We show that Arg‐rich peptides selectively unfold RNA G‐quadruplexes, but not RNA stem‐loops or DNA/RNA duplexes. This length‐dependent activity is inhibited by acidic residues and is conserved among SR and SR‐related proteins (SRSF1, SRSF3, SRSF9, U1‐70K, and U2AF1).

Automatic Modal Wavefront Estimation and Correction for Optical Aberration

IEEE Photonics Journal, 2019
Modal estimation of aberration can quantify the amount of aberration, which plays an important role in optical system optimization, aberration correction, and so on. Here, we propose a simple but effective method to find the modal wavefront of aberration.

Overcoming the penetration depth limit in optical microscopy: Adaptive optics and wavefront shaping [PDF]

Journal of Innovative Optical Health Sciences, 2019
Despite the unique advantages of optical microscopy for molecular specific high resolution imaging of living structure in both space and time, current applications are mostly limited to research settings.

PARP inhibitors elicit distinct transcriptional programs in homologous recombination competent castration‐resistant prostate cancer

Molecular Oncology, EarlyView.
PARP inhibitors are used to treat a small subset of prostate cancer patients. These studies reveal that PARP1 activity and expression are different between European American and African American prostate cancer tissue samples. Additionally, different PARP inhibitors cause unique and overlapping transcriptional changes, notably, p53 pathway upregulation.

Realization of Zero-Refractive-Index Lens with Ultralow Spherical Aberration

, 2016
Optical complex materials offer unprecedented opportunity to engineer fundamental band dispersion which enables novel optoelectronic functionality and devices. Exploration of photonic Dirac cone at the center of momentum space has inspired an exceptional

Harmonically matched grating-based full-field quantitative high-resolution phase microscope for observing dynamics of transparent biological samples [PDF]

, 2007
We have developed a full-field high resolution quantitative phase imaging technique for observing dynamics of transparent biological samples. By using a harmonically matched diffraction grating pair (600 and 1200 lines/mm), we were able to obtain non ...
