Artificial structures for human‐machine interfaces with closed‐loop interaction

open access: yesFlexMat, EarlyView.
Artificial structures bridge sensing and feedback in closed‐loop human‐machine interfaces by providing geometry‐enabled mechanical and functional programmability. This review maps the role of artificial structures in diverse sensing modalities and feedback strategies, and illustrates their integration into closed‐loop interaction systems, highlighting ...

Enhancement of Chemical Stability of Sulfonated Polyvinylidene Fluoride Proton‐Conducting Membranes by Ceria Incorporation

open access: yesJournal of Polymer Science, EarlyView.
The chemical stability of SPVDF membranes was examined using Fenton's reagent test. It was found that the chemical stability of membranes was enhanced from around 80% to 96% by integration of ceria in the membranes. The ability of ceria to toggle between the two oxidation states was responsible for this enhancement.

The continuing significance of chiral agrochemicals

open access: yesPest Management Science, Volume 81, Issue 4, Page 1697-1716, April 2025.
In the time frame 2018–2023, around 43% of the 35 chiral agrochemicals introduced to the market (herbicides, fungicides, insecticides, acaricides, and nematicides) contain one or more stereogenic centers in the molecule, and almost 69% of them have been marketed as racemic mixtures of enantiomers or stereoisomers.

Effects of Sediment‐Control Operations on Fish and Macroinvertebrate Communities in Dam Reservoirs

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT Sediments are avoided in many river and dam managements because of their adverse effects on water usage and flood control. Recently, sedimentation control measures, including sluicing, have been employed to manage sediments in river channels and restore communities in dammed rivers.

Evaluating structural resistance and updating modeling uncertainties through testing

open access: yesStructural Concrete, EarlyView.
Abstract The aging of infrastructure necessitates a robust and rational methodology for the assessment of existing structures. Design codes provide general models which cover different design scenarios and are thus overly conservative. Also, such design approaches lack field data and, if applied directly to existing works, often lead to unnecessarily ...

Network Structure and the Efficiency Gains from Mergers: Evidence from U.S. Freight Railroads

open access: yesThe RAND Journal of Economics, EarlyView.
ABSTRACT The trade‐off between market power and efficiency gains is central to antitrust analyses of mergers, but empirical evidence quantifying efficiencies remains limited. Using transaction‐level data from U.S. freight railroads (1985–2005), this article quantifies merger‐induced cost efficiencies, driven mainly by eliminating inter‐railroad ...
