A Beliaev Theory Incorporating a Semi-Phenomenological Roton Backflow Effect
We have developed a Beliaev theory incorporating a semi-phenomenological roton backflow effect in order to examine the effect of the backflow on the Quantum Evaporation of atoms from the free surface of superfluid 4He.

Flexible photocatalytic materials: From substrate engineering to multi‐field synergistic enhancement
This review examines flexible photocatalytic systems, covering substrate evolution from polymers to biomass, fabrication methods like electrospinning, and key mechanical and optoelectrochemical metrics under deformation. Enhancement strategies are critically discussed, followed by applications in energy conversion, environmental remediation, and ...

What's New? This study introduces a novel approach for detecting locally advanced esophageal carcinoma using cell‐free DNA (cfDNA) analysis through a highly sensitive fragmentome assay. Unlike traditional sequencing‐based methods that are limited by the absence of specific mutations in esophageal tumors, our method offers an alternative by quantifying ...

Schematic depicting a gut‐brain pathway that exacerbates CST injury after ICH. Gut Microbiota Dysbiosis‐Mediated Gut NLRP3 Inflammasome Activation Exacerbates Corticospinal Tract Injury After Intracerebral Hemorrhage. Abstract Intracerebral hemorrhage (ICH) causes severe neurological deficits largely attributable to corticospinal tract (CST) injury ...

ABSTRACT Mitochondrial F1FO‐ATPase is classically viewed as the “splendid” rotary nanomachine that sustains life by converting the proton‐motive force (pmf) into ATP. Yet this same complex can adopt a second, context‐dependent function that links bioenergetics to cell fate.

Designing and Testing of Backflow-Free Catheters
Convection-enhanced delivery (CED) is a drug delivery technique used to target specific regions of the central nervous system (CNS) for the treatment of neurodegenerative diseases and cancer while bypassing the blood–brain barrier (BBB).

Intelligent Continuum Micromachines in Complex Confined Spaces
The cover depicts a conceptual design for an intelligent continuum micromachine entering a target capsule used in fusion‐energy research through its slender gas‐fill tube. By combining route‐adaptive deformation, embedded sensing, and a functional end effector, the robot could inspect hidden defects, assess local conditions, and support localized ...

Steady‐State and Dynamic Behavior of Geometry‐Tunable Microfluidic Passive Flow Regulators
Passive microfluidic flow regulators exhibit geometry‐dependent dynamic behavior, where channel width governs the resistance–compliance interactions within the system. Narrow channels produce faster responses with higher bandwidth, while wider channels yield slower responses and stronger attenuation.

Energy Backflow in Unidirectional Monochromatic and Space–Time Waves
Backflow, or retropropagation, is a counterintuitive phenomenon whereby for a forward-propagating wave the energy locally propagates backward. In the context of backflow, physically most interesting are the so-called unidirectional waves, which contain ...

Vortices and Backflow in Hydrodynamic Heat Transport
Recent experiments have provided compelling and renewed interest in phonon hydrodynamics. At variance with ordinary diffusive heat transport, this regime is primarily governed by momentum-conserving phonon collisions. At the mesoscopic scale it can be described by the viscous heat equations (VHE), that resemble the Navier-Stokes equations (NSE) in the ...
