Artificial Cilia for 360° Direction‐Sensitive Acoustic Sensing Through Additive Micromanufacturing
An artificial cilium using additive micro‐manufacturing technologies for direction‐sensitive acoustic sensing is prepared, including electrospray and 3D micro‐direct ink writing. Two resonances are achieved on a cilium by printing two independent electrode‐to‐electrode interconnect bridges.

Low frequency acoustics in solid $^4$He at low temperature
The elastic properties of hcp $^4$He samples have been investigated using low frequency (20 Hz to 20 kHz) high sensitivity sound transducers. In agreement with the findings of other workers, most samples studied grew very significantly stiffer at low ...

Shape Morphing Programmable Systems for Enhanced Control in Low‐Velocity Flow Applications
A soft, Lorentz‐force‐driven programmable surface enables rapid, reversible shape morphing for active flow control. Integrating experimental, numerical, and modeling approaches, the system demonstrates effective modulation of near‐wall flow and momentum at low velocities, offering pathways for bio‐inspired aerodynamics and natural locomotion emulation.

Abstract Domesticated European rabbits (Oryctolagus cuniculus) have long been chosen as laboratory model organisms. Despite this, there has been no definitive study of the vertebral musculature of wild rabbits. Relevant descriptions of well‐studied veterinary model mammals (such as dogs) are generally applicable, but not appropriate for a species ...

Harvesting AAV by tangential flow filtration using reverse asymmetric membranes
Abstract Efficient bioreactor clarification for harvesting virus particles is often challenging. Tangential flow filtration is attractive as it can be easily adapted for batch and perfusion operations. Here the feasibility of using reverse asymmetric hollow fiber membranes, where the more open support structure faces the feed stream, has been ...

The graphic enables the visualization of the changes in audible frequency within the cell when the potential is applied at 30 s. The change in frequency is related to the gas volume produced during electrolysis. The gas changes the compressibility of the electrolyte slowing down the speed of sound.

The ABDOPOCUS‐HF trial is a randomized, single‐blind, low‐intervention clinical trial (n = 168) investigating the utility of intra‐abdominal pressure (IAP) and point of care ultrasound to guide decongestive therapies during the first 72 hours after admission for acute heart failure.

Visual Patterns of Diaphragmatic Motion in Acute Respiratory Failure: A Prospective Pilot Study
In this prospective bicentric study, we studied the relationship between the appearance of diaphragmatic motion and the etiological diagnosis of patients admitted to the emergency department with ARF. We observed a different visual pattern in patients with pneumonia. This is an interesting result as it allows the diagnosis of pneumonia without the need
