The quantification of three-dimensional (3D) flow structures and particle dynamics is crucial for unveiling complex interactions in turbulent flows. This review summarizes recent advances volumetric detection 3D velocimetry involving holography. We introduce the fundamental principle holography discuss debilitating depth-of-focus problem, along with methods that have been implemented to circumvent it. focus this on development in-line digital general, holographic microscopy particular. A...
Better understanding of particle-particle and particle-fluid interactions requires accurate 3D measurements particle distributions motions. We introduce the application in-line digital holographic microscopy as a viable tool for measuring dense micrometer (3.2 microm) submicrometer (0.75 particles in liquid solution with large depths 1-10 mm. By recording magnified hologram, we obtain depth field approximately 1000 times object diameter reduced focus 10 diameters, both representing...
Understanding how bacteria move close to surfaces is crucial for a broad range of microbial processes including biofilm formation, bacterial dispersion, and pathogenic infections. We used digital holographic microscopy capture large number (>10(3)) three-dimensional Escherichia coli trajectories near far from surface. found that within 20 μm surface tumbles are suppressed by 50% reorientations largely confined surface-parallel directions, preventing escape the near-surface region. A...

We focus on Karlodinium veneficum Pfiesteria piscicida, mixotrophic heterotrophic respectively, their preys. Nearest-neighbor distance shows that predator prey...
Toxins produced by the harmful algal bloom (HAB) forming, mixotrophic dinoflagellate Karlodinium veneficum have long been associated with fish kills. To date, perceived ecological role for toxins has relief from grazing pressures. Here, we demonstrate that karlotoxins also serve as a predation instrument. Using high-speed holographic microscopy, measure swimming behavior of several toxic and nontoxic strains K. their prey, Storeatula major , within dense suspensions. The selected produce...
Nanoplastic pollution is increasing worldwide and poses a threat to humans, animals, ecological systems. High-throughput, reliable methods for the isolation separation of NMPs from drinking water, wastewater, or environmental bodies water are interest. We investigated iron oxide nanoparticles (IONPs) with hydrophobic coatings magnetize plastic particulate waste removal. produced tested IONPs synthesized using air-free conditions in atmospheric air, coated several polydimethylsiloxane...
A brief review of some the recent results on 30 to 50 day time scale is presented in this paper. We have examined divergent circulations days during FGGE year.

Better understanding of bacteria environment interactions in the context biofilm formation requires accurate 3-dimentional measurements motility. Digital Holographic Microscopy (DHM) has demonstrated its capability resolving 3D distribution and mobility particulates a dense suspension. Due to their low scattering efficiency, are substantially difficult be imaged by DHM. In this paper, we introduce novel correlation-based de-noising algorithm remove background noise enhance quality hologram....
Treatment of osteoarthritis (OA) remains a significant clinical challenge. Itaconate (IA), an emerging regulator intracellular inflammation and oxidative stress, may potentially be harnessed to treat OA. However, the short joint residence time, inefficient drug delivery, cell-impermeable property IA can seriously hamper translation. Herein, IA-encapsulated zeolitic imidazolate framework-8 (IA-ZIF-8) nanoparticles were self-assembled by zinc ions, 2-methylimidazole, render them pH-responsive....
Holographic particle image velocimetry (HPIV) is presently the only method that can measure at high resolution all three components of velocity in a finite volume. In systems are based on recording one hologram, parallel to hologram be measured throughout sample volume, but elongation traces depth direction severely limits accuracy component perpendicular hologram. Previous studies overcame this limitation by simultaneously two orthogonal holograms, which inherently required four windows and...
Abstract Two dynamical models are used to perform a series of seasonal predictions. One model, referred as GCM2, was designed general circulation model for climate studies, while the second one, SEF, numerical weather prediction. The predictions cover 26‐year period 1969–1994. For each four seasons, ensembles six forecasts produced with runs starting from initial conditions hours apart. sea surface temperature (SST) anomaly month prior start forecast is persisted through three‐month...

Sarcasm is a sophisticated linguistic phenomenon and commonly manifests on social media platforms, which poses great challenge for opinion mining systems. Therefore, multimodal sarcasm detection, aims to understand the implied sentiment in video, has gained more attention. However, previous works mostly focus feature fusion without explicitly modeling incongruity between modalities, such as expressing verbal compliments while rolling eyes, an obvious cue detecting sarcasm. In this article,...
