Vector beams have drawn considerable interest recently because of their unique properties in the transverse plane. Here we experimentally realize optical storage of a vector beam of light in a warm cell. The vector beam is tailored using a Sagnac interferometer containing an internal vortex phase plate, and the light pulse is stored in warm rubidium vapor. The preservation of both the spatial structure and the phase information is verified after retrieval. The implementation of vector beam storage in a room-temperature memory has potential for use in the fabrication of versatile vortex-based quantum networks.

Human induced pluripotent stem cell-derived cardiomyocytes (iPSC-CMs) are an important resource for identifying novel therapeutic targets and cardioprotective drugs. However, a key limitation of iPSC-CMs is their immature, fetal-like phenotype. Cultivation of iPSC-CMs in lipid-supplemented maturation media (MM) enhances the structural, metabolic and electrophysiological properties of iPSC-CMs.

Objectives: This retrospective study evaluates alveolar bone remodeling patterns and their association with incisor displacement in adults undergoing clear aligner therapy with premolar extractions for Class II malocclusion correction.
Methods: Cone-beam computed tomography (CBCT) scans of 38 maxillary and 37 mandibular incisors were analyzed. Displacement vectors for four anatomical landmarks (cusp tip [C], root apex [R], root neck midpoint [M], labial cementoenamel junction [L]) were quantified.
We describe a simple and effective method for the experimental generation of a variety of vector beams, including vector Laguerre-Gauss (vLG) and vector Bessel-Gauss (vBG), and experimentally realize vector Mathieu-Gauss (vMG) beams for the first time, to the best of our knowledge. We require only a single binary hologram on a Digital Micromirror Device (DMD) and use two orthogonally polarized beams with complex conjugate amplitudes to obtain independent control over both the phase and polarization structure of the generated fields. We characterize the beams using intensity measurements and Stokes polarimetry, and quantify their vector quality through concurrence.

In vivo genome editing has the potential to address many inherited and environmental disorders. However, a major hurdle for the clinical translation of genome editing is safe, efficient delivery to disease-relevant tissues. A modality-agnostic reporter animal model that facilitates rapid, precise, and quantifiable assessment of functional delivery and editing could greatly enhance the evaluation and translation of delivery technologies.

The scattering interaction between a circularly polarized Bessel pincer light-sheet beam and a chiral particle is investigated within the framework of generalized Lorenz-Mie theory (GLMT). The incident electric field distribution is rigorously derived via the vector angular spectrum decomposition method (VASDM), with subsequent determination of the beam-shape coefficients (BSCs) pmnu and qmnu through multipole expansion in the basis of vector spherical wave functions (VSWFs). The expansion coefficients for the scattered field (AmnsBmns) and interior field (AmnBmn) are derived by imposing boundary conditions.
