The lateral vibrations of sharply-pointed bars [PDF]

open access: yesProceedings of the Royal Society of London. Series A, Containing Papers of a Mathematical and Physical Character, 1920
Abstract In a preceding paper, a discussion was given of the lateral vibrations of bars of circular cross-section formed by the revolution of the curve y = Axn —when n is between the values zero and unity—about the axis of x. The matter arose in connection with the siliceous deposits found upon a certain type of sponge spicule, as ...

Architectural Characterization of Meandering River Reservoirs with Dense Well Patterns: Northern Block Zhong-2, Gudao Oilfield

open access: yesApplied Sciences
The meandering river reservoirs of the Ng3–Ng4 members of the upper Guantao Formation in northern Middle Block 2, Gudao Oilfield, exhibit sand bodies with rapid lateral variation, complex contacts, and strong heterogeneity.

Identifying the pool-point bar location based on experimental investigation

open access: yesJournal of Water and Land Development, 2019
Morphological relationships of meander evolution in terms of hydraulic and geometric characteristics are essential for river management. In present study, an experimental based study of meander evolution was employed to develop a prediction formula for ...

A Feasibility Study of a Vibrotactile System Based on Electrostatic Actuators for Touch Bar Interfaces: Experimental Evaluations

open access: yesApplied Sciences, 2021
Vibrotactile feedback is a very desirable feature for many touchscreen applications, creating a more engaging and effective user experience. Although it is common in small electronic devices, this feedback is often absent in large touchscreen devices ...

Stochastic Modeling of Thin Mud Drapes Inside Point Bar Reservoirs With ALLUVSIM‐GANSim

open access: yesWater Resources Research
Modeling inclined fine‐scale mud drapes inside point bars, deposited on accretion surfaces during stages of low energy or slack water, is critical to modeling fluid flow in complex sedimentary environments (e.g., fluvial and turbidity flows).

Salt Bridge Formation between the I-BAR Domain and Lipids Increases Lipid Density and Membrane Curvature

open access: yesScientific Reports, 2017
The BAR domain superfamily proteins sense or induce curvature in membranes. The inverse-BAR domain (I-BAR) is a BAR domain that forms a straight “zeppelin-shaped” dimer.

Role of flood discharge in shaping stream geometry: Analysis of a small modern stream in the Uinta Basin, USA

open access: yesJournal of Palaeogeography, 2017
This small modern river system is located on a relatively flat (about 1°–2°), unconsolidated sandy pediment surface in the Uinta Basin of Utah, USA, and it is with a scale of about 30 m long and 0.4–0.8 m wide, similar as a natural flume experiment model.

Multiplexed volumetric bar-chart chip for point-of-care diagnostics [PDF]

open access: yesNature Communications, 2012
Microfluidics have become an enabling technology for point-of-care and personalized diagnostics. Desirable capabilities of microfluidics-based diagnostic devices include simplicity, portability, low cost and the performance of multiplexed and quantitative measurements, ideally in a high-throughput format.
