Fluid flow in the impulse valve of a hydraulic ram [PDF]

, 2019
The paper presents the results of a study investigating the equilibrium of forces acting on the closing element of the impulse valve in a water ram at the end of the acceleration stage. Acceleration is one of the three main stages in the working cycle of

Experimental validation of a test gas substitution for simulating non-equilibrium giant planet entry conditions in impulse facilities [PDF]

, 2020
Scaled giant planet entry testing is beyond the simulation capability of most impulse facilities, which limits the ground testing data available for computational model validation.

A Robust Control Approach to Understanding Nonlinear Mechanisms in Shear Flow Turbulence [PDF]

, 2010
A robust control framework is used to investigate a streamwise constant projection of the Navier Stokes equations for plane Couette flow. Study of this streamwise constant model is motivated by both numerical and experimental observations that suggest ...

Function of a Fly Motion-Sensitive Neuron Matches Eye Movements during Free Flight [PDF]

, 2005
Sensing is often implicitly assumed to be the passive acquisition of information. However, part of the sensory information is generated actively when animals move.

Pull‐and‐Push Nanotherapeutic Hydrogels: Scavenging Inflammatory Triggers While Driving Tissue Regeneration in Burn Wounds

Advanced Functional Materials, EarlyView.
A nanounit‐assembled hydrogel employing a “pull‐and‐push” strategy simultaneously scavenges pro‐inflammatory cell‐free DNA (cfDNA) and delivers regenerative therapeutics in response to burn‐induced hyperthermia. By repolarizing macrophages and promoting angiogenesis, this multifunctional platform accelerates burn wound healing, offering a blueprint for
