UG^2: a Video Benchmark for Assessing the Impact of Image Restoration and Enhancement on Automatic Visual Recognition

open access: yes, 2018
Advances in image restoration and enhancement techniques have led to discussion about how such algorithmscan be applied as a pre-processing step to improve automatic visual recognition. In principle, techniques like deblurring and super-resolution should

Kinesin‐Induced Buckling Reveals the Limits of Microtubule Self‐Repair

open access: yesAdvanced Science, EarlyView.
This study shows that kinesin‐driven buckling induces extensive microtubule lattice damage that often exceeds intrinsic self‐repair and leads to filament failure. While curvature, motor motility, and force individually cause limited damage, their combination overwhelms repair.

Cluster‐Mediated Solute Stabilization and Shear‐Bypass Synergistic Strengthening in High‐Alloyed Systems

open access: yesAdvanced Science, EarlyView.
This study demonstrates that in high‐alloy systems, nanoclusters with high solute tolerance can effectively suppress compositional segregation. This mitigation leads to a concurrent 18.7% increase in strength and 41.5% improvement in ductility, which is attributed to a shear‐bypass synergistic strengthening mechanism. The findings provide a new pathway

An unmanned surface vehicle for acoustic telemetry surveys of coastal fishes: range testing, real world performance, and comparison with a stationary tracking array

open access: yesFrontiers in Marine Science
Ocean gliders equipped with acoustic telemetry receivers offer a promising approach for studying the movement of marine fishes, yet most surveys to date have been brief and rarely include direct comparisons with traditional stationary tracking methods ...

Two‐Dimensional Triferroics: From Fundamental Couplings to Multifunctional Applications

open access: yesAdvanced Science, EarlyView.
This graphic summarizes the three main types of currently reported 2D triferroic couplings. From the structural perspective, existing systems can be broadly classified into two categories, which exhibit distinct symmetry features and coupling behaviors. Beyond the lattice difference, a third type involves the interplay among ferroelectricity, magnetism,

Local information transfer as a spatiotemporal filter for complex systems

open access: yes, 2008
We present a measure of local information transfer, derived from an existing averaged information-theoretical measure, namely transfer entropy. Local transfer entropy is used to produce profiles of the information transfer into each spatiotemporal point ...

Rigid‐Flexible Coupling Units Enable Robust Large Birefringence

open access: yesAdvanced Science, EarlyView.
A rigid–flexible coupling strategy, combining flexible (S3)2− linear units with rigid (VO4)3− tetrahedra, yields Sr4(VO4)2S3—a robust crystal exhibiting large birefringence (Δn = 0.52@550 nm) and remarkable thermal, air, and water stability. ABSTRACT Birefringent crystals are central to polarization control in laser technologies (e.g., wave plates and ...

From Materials to Systems: Challenges and Solutions for Fast‐Charge/Discharge Na‐Ion Batteries

open access: yesAdvanced Energy Materials, EarlyView.
This review systematically analyzes the key characteristics limiting the fast‐charge/discharge capability of Na‐ion batteries (SIBs) from a multi‐scale perspective encompassing electrode materials, the electrode‐electrolyte interface, and the system. Furthermore, it presents practical solution strategies for the fundamental issues arising at each scale,

A theoretical and flight test study of pressure fluctuations under a turbulent boundary layer. Part 2: Flight test study [PDF]

open access: yes
The study of pressure fluctuations under a turbulent boundary layer was undertaken with the objective of extending previous work to lower frequencies. Wind tunnel and flight test measurements are invalid at low frequencies because of extraneous acoustic ...
