Acoustic Rayleigh Wave Turbulence in Soft Viscoelastic Matter

open access: yesAdvanced Science, EarlyView.
Discrete acoustic Rayleigh wave turbulence (DARWT) is observed on the free surface of viscoelastic materials under monochromatic excitation. Governed by bulk shear rigidity supporting inertial modes against surface tension, the nonlinear Rayleigh waves exhibit distinct power‐law scaling and turbulence features in their Kolmogorov–Zakharov spectra. This

Workflow for computational fluid dynamics modeling of fixed‐bed reactors packed with metal foam pellets: Hydrodynamics

open access: yesAIChE Journal, Volume 69, Issue 1, January 2023., 2023
Abstract In recent years, the catalyst pellets made of open‐cell metallic foams have been identified as a promising alternative in fixed‐bed reactors. A reliable modeling tool is necessary to investigate the suitability of different foam properties and the shapes of foam pellets.

Pan‐Variant SARS‐CoV‐2 Vaccines Induce Protective Immunity by Targeting Conserved Epitopes

open access: yesAdvanced Science, EarlyView.
An integrative approach identifies conserved B‐cell and T‐cell epitopes within SARS‐CoV‐2 proteins, redirecting immune responses from variable to conserved regions. These epitopes elicit robust humoral and cellular immunity, neutralizing diverse viral variants. Promiscuous T‐cell epitopes demonstrate cross‐species efficacy, highlighting their potential

Online machine learning modeling and predictive control of nonlinear systems with scheduled mode transitions

open access: yesAIChE Journal, Volume 69, Issue 2, February 2023., 2023
Abstract This work develops a model predictive control (MPC) scheme using online learning of recurrent neural network (RNN) models for nonlinear systems switched between multiple operating regions following a prescribed switching schedule. Specifically, an RNN model is initially developed offline to model process dynamics using the historical ...

Structural Basis and Mechanism of a Unique Haemophore in the Haem‐Iron Acquisition by Riemerella anatipestifer

open access: yesAdvanced Science, EarlyView.
This study reveals the structural basis and mechanism of RhuH as a haemophore in Riemerella anatipestifer. Secreted by outer membrane vesicles (OMVs), RhuH captures haem with high affinity from host hemoglobin in two forms: a) released from OMVs, binding and transferring haem to outer membrane receptor, and b) haem‐bound on the OMVs surface, returning ...

Regulation of Liquid Self‐Transport Through Architectural‐Thermal Coupling: Transitioning From Free Surfaces to Open Channels

open access: yesAdvanced Science, EarlyView.
Inspired by the skin of the Texas horned lizard, hierarchical structures composed of primary wedged grooves and secondary capillary crura are proposed, and the regulation of liquid self‐transport is achieved through architectural and thermal coupling, transitioning from free surfaces to open channels.

High‐Fidelity Computational Microscopy via Feature‐Domain Phase Retrieval

open access: yesAdvanced Science, EarlyView.
An innovative phase retrieval framework, termed FD‐PR, is uniquely established in the image's feature domain through the feature‐extracted, physical‐driven regression with interfaces for combining physics and image processing constraints. FD‐PR takes advantage of invariance components of an image against presences of model mismatch and uncertainty ...
