Rational Tuning of Hygroscopic Oscillation of Stacked Nanoflake Assemblies for Continuous Ambient Energy Harvesting

open access: yesAdvanced Materials, EarlyView.
Stacked nanoflake assembly (SNA) membranes can oscillate autonomously, offering opportunities for soft actuation and energy harvesting. This work uncovers the physical mechanism behind the sustained oscillation of SNA membranes in gradient humidity and identifies three governing dimensionless parameters, enabling rational design for optimizing SNA ...

Tidal Datums with Spatially Varying Uncertainty in North-East Gulf of Mexico for VDatum Application

open access: yesJournal of Marine Science and Engineering, 2018
We conducted a VDatum-spatially varying uncertainty study for the North-East Gulf of Mexico. The newly developed tide model incorporated the latest available National Ocean Service (NOS) bathymetry survey data and National Geodetic Survey (NGS) shoreline

Numerical simulations of generation and propagation of internal tides in the Andaman Sea

open access: yesFrontiers in Marine Science, 2022
The generation and propagation of internal tides in the Andaman Sea are investigated using a three-dimensional high-resolution numerical model. Three categories of experiments, including driving the model with four main semidiurnal tides (M2, S2, N2, and

Respiratory Signal Processing and Analysis Using Flexible Capacitive Sensor Data

open access: yesAdvanced Materials Technologies, EarlyView.
Capacitive pressure sensors based on poly(glycerol sebacate) (PGS) substrates are developed for continuous, non‐invasive respiratory monitoring. Integrated with a signal processing algorithm, they enable accurate tracking of thoracic expansion and retraction.

Mangrove sedimentary characteristics and implications for crab Ucides cordatus (Crustacea, Decapoda, Ucididae) distribution in an estuarine area of the Amazonian region [PDF]

open access: yesActa Amazonica, 2013
At the coastal zone sediments, water and organisms interact intensely. At equatorial tidal-dominated coast mangroves are abundant. These areas are well-known for their ecological importance.

Structural Modulation of Charge Transfer in Donor–Acceptor Systems: Effects of Donor Type and Connectivity

open access: yesAdvanced Optical Materials, EarlyView.
A coherent phthalimide acceptor platform with planar (Cz—carbazole) and spiro‐type (SAF—spiroacridine fluorene) donors enables systematic tuning of donor geometry and coupling, driving the evolution of excited‐state topology from classical CT‐TADF and fluorescence/RTP to CT‐driven and LE‐assisted TADF with OLED efficiencies ≈ 36%.

Tidal currents in the Yucatan Channel [PDF]

open access: yesGeofísica Internacional, 2007
Currents data from a ten-month period at 197 measuring points covering all Yucatan Channel were processed by harmonic analysis to estimate tidal parameters for the O1, K1, M2 and S2 components.

Solid Harmonic Wavelet Bispectrum for Image Analysis

open access: yesAdvanced Science, EarlyView.
The Solid Harmonic Wavelet Bispectrum (SHWB), a rotation‐ and translation‐invariant descriptor that captures higher‐order (phase) correlations in signals, is introduced. Combining wavelet scattering, bispectral analysis, and group theory, SHWB achieves interpretable, data‐efficient representations and demonstrates competitive performance across texture,

A Two-Stage Model for Factors Influencing Citation Counts

open access: yesPublications
This work aims to use a suitable regression model to study a count response random variable, namely, the number of citations of a research paper, that is affected by some explanatory variables.

Feeding ecology of 0-group sea bass Dicentrarchus labrax in salt marshes of Mont Saint-Michel bay (France) [PDF]

open access: yes, 2001
0-group sea bass, Dicentrarchus labrax, colonize intertidal marsh creeks of Mont Saint Michel Bay, France, on spring tides (e.g., 43% of the tides) during flood and return to coastal waters during ebb.
