Direct measurement of bidirectional turbulent fluxes of atmospheric cluster ions

Quarterly Journal of the Royal Meteorological Society, EarlyView.
First direct eddy covariance measurements of vertical turbulent fluxes of atmospheric cluster ions are presented. The net turbulent flux was mostly positive for negative cluster ions (net emission of negative ions) and mostly negative for positive cluster ions (net deposition of positive ions).

Why Autonomous Vehicles Are Not Ready Yet: A Multi‐Disciplinary Review of Problems, Attempted Solutions, and Future Directions

Journal of Field Robotics, EarlyView.
ABSTRACT Personal autonomous vehicles can sense their surrounding environment, plan their route, and drive with little or no involvement of human drivers. Despite the latest technological advancements and the hopeful announcements made by leading entrepreneurs, to date no personal vehicle is approved for road circulation in a “fully” or “semi ...

Mapping River Bed Topography in Whitewater Rapids Using Bathymetric LiDAR

River Research and Applications, EarlyView.
ABSTRACT Bathymetric LiDAR captures river topography efficiently for clear and shallow water, but for mountain rivers, whitewater rapids still pose challenges. This study proposes a novel method to enable the extraction of bottom returns specifically in turbulent whitewater sections.

Exploring Wide‐Range Alkyl Bridge Length Variations in Polymer Semiconductors: From Pristine to Blend Films for High‐Mobility Stretchable TFTs

Small, EarlyView.
A side‐chain engineering strategy enables polymer semiconductors to achieve record‐high mobility and mechanical resilience in intrinsically stretchable transistors. By correlating crystallinity with charge transport and stretchability, this work establishes a predictive design rule.

Machine Learning‐Driven Nanopore Sensing for Quantitative, Label‐Free miRNA Detection

Small Methods, EarlyView.
Nanopore sensors combined with DNA‐barcoded probes enable detection of multiple biomarkers in parallel at the single‐molecule level through characteristic delays in ionic current signals. Three analytical strategies are compared: moving standard deviation, spectral entropy, and a convolutional neural network (CNN). The CNN achieves superior sensitivity

Additive Manufacturing of Hot‐Work Tool Steel by In Situ Alloying Using Laser Powder Bed Fusion and Directed Energy Deposition—Strategies to Improve Chemical Homogeneity

steel research international, EarlyView.
To support future alloy development a powder mixture is processed by laser additive manufacturing. The powder mixture containing Mo‐ and W‐rich tracers is processed by powder bed fusion using single and double laser exposure and by directed energy deposition which provides drastically enlarged melt pools.

“Being Nice” as Modus Vivendi in Classrooms: A Collective Behavior Approach to Deviant Behavior in Primary Schools

Symbolic Interaction, EarlyView.
This study of first‐year primary school draws on Goffman's concept of “collective behavior” to examine how order is established and disrupted through the mutual adjustment of all participants' actions. We employed a multi‐method longitudinal design, using semi‐standardized observations and qualitative interviews with teachers and children at three ...

Chinese Guidelines for the Diagnosis and Surgical Treatment of Adult Obstructive Sleep Apnea (2024)

World Journal of Otorhinolaryngology - Head and Neck Surgery, EarlyView.
ABSTRACT Obstructive sleep apnea (OSA) is a common chronic disorder characterized by abnormal breathing during sleeping. OSA can damage various organs throughout the body and is burdensome, both socially and economically. Moreover, as OSA has been increasingly studied in recent years, new evidence‐based guidelines for its diagnosis and surgical ...
