Aerodynamic noise from a train pantograph

open access: yes, 2014
Many studies have shown that when the speed of high speed trains exceeds around 300km/h, aerodynamic noise becomes the most significant noise source. The pantograph, or current collector, is mounted on the top of the train and is therefore not shielded ...

The Landscape of Long Non‐Coding RNAs Provides Insights Into the Domestication and Improvement of Pear Fruit

open access: yesAdvanced Science, EarlyView.
This study reveals that long non‐coding RNAs represent important regulatory components underlying pear domestication and improvement. Integrative multi‐omics analyses identify selected lncRNAs associated with fruit traits, while functional validation uncovers a lignin‐related lncRNA, lncRNA‐pys, that promotes lignin accumulation.

A Comparison of the Aerodynamic Characteristics of Eight Sailwing Airfoil Sections [PDF]

open access: yes, 1979
The operational characteristics of sailwings are discussed with emphasis placed on the importance of the trailing edge cable tension. The three dimensional aerodynamic characteristics were obtained from wind tunnel tests, and the results compared to ...

The CXCL5/CXCR2 Axis Attenuates Ferroptosis in Intrahepatic Cholangiocarcinoma Through the Positive Feedback Loop Between PTGS2 Transcriptional Activation and Neutrophil Recruitment

open access: yesAdvanced Science, EarlyView.
The CXCL5/CXCR2 axis directly inhibits ferroptosis in ICC cells by activating the NF‐κB/PTGS2 pathway. Meanwhile, the CXCL5/CXCR2 axis recruits N2 TANs, and the activated PTGS2 promotes the secretion of TNF‐α from the recruited N2 TANs via the CCL2/CCL7/CCR2 pathway, thereby activating the NF‐κB/PTGS2 axis and forming a positive feedback loop, which ...

Aerodynamic measurements : from physical principles to turnkey instrumentation /

open access: yes, 2011
"Aerodynamic Measurements presents the most comprehensive review of the theoretical bases which experimental techniques used in aerodynamics are based on. Limitations of each method in terms of accuracy, response time, and complexity are addressed.

Architecting Phase‐Selective Interlayers for Stable SiOx Lithium Storage via Dual‐Function Design

open access: yesAdvanced Science, EarlyView.
Silicon anodes offer high capacity but suffer severe volume expansion. Silicon monoxide (SiO) buffers expansion, yet uncontrolled lithiation irreversibly consumes lithium as Li2O and oxygen‐rich silicates. Here, we design a layered SiOx featuring a phase‐selective conductive interfacial interlayer (PSCII), i.e., a Li4SiO4‐rich, ion‐accessible ...

Entropy‐Driven Physical Amplification in Multivalent Biosensing

open access: yesAdvanced Science, EarlyView.
Detecting scarce molecules usually demands enzymatic amplification such as PCR. A statistical‐mechanical theory now reveals a purely physical alternative: distributing a fixed binding strength over more linker arms exponentially lowers the concentration at which multivalent sensors switch on.
