Analysis and mitigation of numerical dissipation in inviscid and viscid computation of vortex-dominated flows [PDF]

The conservative unsteady Euler equations for the flow relative motion in the moving frame of reference are used to solve for the steady and unsteady flows around sharp-edged delta wings.

Broadband Achromatic Programmable Electromagnetic Camouflage via Fluidic‐Accessible Metasurface

Advanced Science, EarlyView.
A fluidic access metasurface enables dynamic, broadband electromagnetic illusions. By physically reconstructing conductive patterns with liquid metal, the metasurface achieves real‐time, pixel‐level control over phase dispersion. This allows for the programmable generation of arbitrary strong scattering point arrays, effectively deceiving high ...

Flow structures in end-view plane of slender delta wing

EPJ Web of Conferences, 2017
Present investigation focuses on unsteady flow structures in end-view planes at the trailing edge of delta wing, X/C=1.0, where consequences of vortex bursting and stall phenomena vary according to angles of attack over the range of 25° ≤ α ≤ 35° and yaw

Study of Resistive Switching Dynamics and Memory States Equilibria in Analog Filamentary Conductive‐Metal‐Oxide/HfOx ReRAM via Compact Modeling

Advanced Electronic Materials, EarlyView.
A physics‐based compact model for Conductive‐Metal‐Oxide/HfOx ReRAM, accounting for ion dynamics, electronic conduction, and thermal effects, is presented. Accurate and versatile simulations of analog non‐volatile conductance modulation and memory state stabilization enable reliable circuit‐level studies, advancing the optimization of neuromorphic and ...

How Does Cultural and Colonial Heritage Affect Optimal Branding Strategies? Evidence From the Rice Sector in Senegal

Agribusiness, EarlyView.
ABSTRACT Africa's cultural and colonial heritage has profoundly segmented rice markets. Whereas in ancient centers of rice domestication, consumers maintained preferences for local rice consistent with their cultural heritage, preferences have shifted toward imported Asian rice in coastal areas around seaports, due to prior exposure to colonial import ...

Molecular‐Scale Tuning of Low‐Molecular‐Weight Gelators Controls Supramolecular Assembly and Directs Human Mesenchymal Stem Cell Growth

Angewandte Chemie, EarlyView.
Chemistry in charge of biology! Simple low‐molecular‐weight gelators, with minor modifications in molecular structure, self‐assemble differently and can also co‐assemble when simultaneously triggered. This creates a family of gels with different properties that direct the growth of stem cells in different ways.
