Housing: boom or bubble? [PDF]

In recent years, the U.S. has seen an extraordinary increase in demand for housing and a rapid rise in house prices. Data show that nationally, the average price of an existing home, adjusted for inflation, rose more than 8 percent in 2004 and 2005, a ...

Durability of Soft Pneumatic Actuators: A Review and Benchmarking Protocol

Advanced Robotics Research, EarlyView.
Lack of durability is a key challenge hindering the broad scale adoption of soft pneumatic actuators (SPAs) in automation industries. This review provides a comprehensive overview of existing research on SPA durability, introduces a standardized durability benchmarking protocol to consolidate the testing of SPAs, and outlines promising directions for ...

Intelligent Micro/Nanorobots for Targeted Interventional Therapy: From Bench to Clinic

Advanced Robotics Research, EarlyView.
Zirui Zhang et al. reviewed the application and challenges of mobile nanomachines in interventional therapy. By converting exogenous energy, including chemical, magnetic, optical, and ultrasonic sources, into mechanical forces, micro/nanorobots (MNRs) enable precise actuation at unprecedented scales. Evolving far beyond traditional drug delivery, these

Reversal of the lift force on an oblate bubble in a weakly viscous linear shear flow [PDF]

, 2009
We compute the flow about an oblate spheroidal bubble of prescribed shape set fixed in a viscous linear shear flow in the range of moderate to high Reynolds numbers.

Autonomous Navigation of Pollen‐Inspired Magnetic Microrobots for Biomedical Applications

Advanced Robotics Research, EarlyView.
A sunflower pollen‐inspired magnetic microrobot enables controlled rolling navigation in vessel‐like environments. Its open geometry reduces hydrodynamic drag, while vision‐based closed‐loop control, shortest‐path planning, and reinforcement learning support target‐reaching and maze navigation with microrobot‐scale accuracy, highlighting a route toward

Bubble evolution and fuzz formation in plasma-facing materials: from ridges to tendrils

Nuclear Fusion
Fuzz formation in plasma-facing materials remains insufficiently understood. We correlate subsurface helium-bubble evolution with surface morphological transitions in tungsten–rhenium (25 atomic %) exposed to high-flux, 90 eV He plasma at ∼1173 K ...

CD9+ B Cells Induce T Follicular Helper Cell Apoptosis to Regulate Germinal Center Regression

Advanced Science, EarlyView.
A unique subset of CD9+ B cells regulates germinal center B (GC‐B) cell regression by inducing T follicular helper (Tfh) cell apoptosis through multiple signaling pathways, such as ALCAM‐CD6. FOXP1 plays a key role in GC‐B cell differentiation. These findings clarify mechanisms of GC degeneration and termination and offer potential targets for adenoid ...

Atomic Tuning of Metal‐Support Interactions for Pathway‐Selective CO2 Photoreduction on TiO2

Advanced Science, EarlyView.
Single‐atom Fe and Cu catalysts anchored on TiO2 steer photocatalytic CO2 reduction toward distinct pathways. Fe sites favor rapid *CO desorption and selective CO formation, whereas Cu sites stabilize *CHO intermediates, enabling deep reduction and C─C coupling. Combined spectroscopy and DFT calculations reveal how metal–support interactions and oxygen

Why Do Small‐Scale Irregularities Migrate Beyond the Equatorial Plasma Bubble?

Geophysical Research Letters
F‐region Field‐Aligned Irregularities (FAIs) observed by the Hainan Coherent Scatter Phased Array Radar (HCOPAR) and the Equatorial Plasma Bubbles (EPBs) observed by four All‐Sky Airglow Imagers (ASAIs) in the night of 4 November 2023 were compared.
