Characterizing Non‐Phase‐Locked Tidal Currents in the California Current System Using High‐Frequency Radar

open access: yesJournal of Geophysical Research: Oceans, Volume 129, Issue 7, July 2024.
Abstract Over 9 years of hourly surface current data from high‐frequency radar (HFR) off the US West Coast are analyzed using a Bayesian least‐squares fit for tidal components. The spatial resolution and geographic extent of HFR data allow us to assess the spatial structure of the non‐phase‐locked component of the tide.

Replication fidelity assessment of large area sub-μm structured polymer surfaces using scatterometry. [PDF]

open access: yes, 2015
The present study addresses one of the key challenges in the product quality control of transparent structured polymer substrates, the replication fidelity of sub-μm structures over a large area.

Intradermal injection of Cutibacterium acnes and staphylococcus: A pustular acne‐like murine model

open access: yesJournal of Cosmetic Dermatology, Volume 23, Issue 7, Page 2478-2489, July 2024.
Abstract Background Skin 16S microbiome diversity analysis indicates that the Staphylococcus genus, especially Staphylococcus aureus (S. aureus), plays a crucial role in the inflammatory lesions of acne. However, current animal models for acne do not fully replicate human diseases, especially pustular acne, which limits the development of anti‐acne ...

SCATTEROMETRY OF 50 NM HALF PITCH FEATURES [PDF]

open access: yes, 2016
Metrology technologies are an essential adjunct to Integrated Circuit (I.C.) Semiconductor manufacturing. Scatterometry, an optical metrology, was chosen to measure 50 nm half pitch feature structures.

Reconstruction of Wide Swath Significant Wave Height From Quasi‐Synchronous Observations of Multisource Satellite Sensors

open access: yesEarth and Space Science, Volume 11, Issue 5, May 2024.
Abstract Global sea wave monitoring is of utmost importance for tasks such as analysis of ocean climate change, offshore fisheries, and early warning of marine disasters. Significant wave height (SWH) is one of the most vital and widely used metrics for measuring sea waves in marine research.

Vertical Velocity Diagnosed From Surface Data With Machine Learning

open access: yesGeophysical Research Letters, Volume 51, Issue 6, 28 March 2024.
Abstract Submesoscale vertical velocities, w, are important for the oceanic transport of heat and biogeochemical properties, but observing w is challenging. New remote sensing technologies of horizontal surface velocity at O(1) km resolution can resolve surface submesoscale dynamics and offer promise for diagnosing w subsurface.

Imaging scatterometry of butterfly wing scales

open access: yesOptics Express, 2008
We describe an imaging scatterometer allowing hemispherical reflectance measurements as a function of the angle of incidence. The heart of the scatterometer is an ellipsoidal reflector, which compresses the hemispherical reflection into a cone-shaped beam that can be imaged by a normal optical system.
