Instrumental Variable Interpretation of Cointegration with Inference Results for Fractional Cointegration [PDF]
, 2002 In this paper we propose an alternative characterization of the central notion of cointegration, exploiting the relationship between the autocovariance and the cross-covariance functions of the series.

System Design Considerations for Magneto‐Electrocatalysis of the Oxygen Evolution Reaction
Small, EarlyView.Electrocatalytic water‐splitting can be controlled using a magnetic field. The commercial prospects are exciting, but the progress is stuck in the fundamental stage of research. Progress is stagnated by publications with conflicting results, incomplete analysis, and inconsistent experimental setups.

Treatment of biodiesel wastewater using ferric chloride and ferric sulfate [PDF]
, 2017 The production of biodiesel through the transesterification method produces a large amount of wastewater that contains high level of chemical oxygen demand (COD) and oil and grease. In this study, coagulation was adopted to treat the biodiesel wastewater.

Two‐Photon Microbubble Printing: Asymmetric Assembly for Continuous Laser Writing
Small, EarlyView.Two‐photon microbubble printing is reported that combines nonlinear photochemistry with thermally driven fluid dynamics. At the laser focus, a distorted vapor bubble induce a strong rear‐to‐front convective flow. By enabling asymmetric assembly, this method allows the continuous formation of nanoparticle aggregates from a wide variety of materials ...

Quantifying stretching and rearrangement in epithelial sheet migration [PDF]
, 2012 Although understanding the collective migration of cells, such as that seen in epithelial sheets, is essential for understanding diseases such as metastatic cancer, this motion is not yet as well characterized as individual cell migration.

Error propagation dynamics of PIV-based pressure field calculations: How well does the pressure Poisson solver perform inherently? [PDF]
Measurement science and technology, 2016 Obtaining pressure field data from particle image velocimetry (PIV) is an attractive technique in fluid dynamics due to its noninvasive nature. The application of this technique generally involves integrating the pressure gradient or solving the pressure

Navigating Gravity: Competing Effects Result in Opposing Taxis for Different Janus Swimmers
Small, EarlyView.The combined effects of gravity and wall‐induced hydrodynamics on the motion of Janus colloids are investigated. Platinum‐ and copper‐coated silica microswimmers show distinct gravitactic alignment near surfaces due to different hydrodynamic couplings. This distinct gravitactic behavior enables separation of initially mixed active particles.

Complex oscillator and Painlev\'e IV equation
, 2015 Supersymmetric quantum mechanics is a powerful tool for generating exactly solvable potentials departing from a given initial one. In this article the first- and second- order supersymmetric transformations will be used to obtain new exactly solvable ...
