Mineta Transportation Institute Says Subways Are Still in Terrorists’ Sights [PDF]

open access: yes, 2014
The FBI arrested a California National Guard reservist on March 17 as he headed for the Canadian border on his way to Syria. Once in Syria, Nicholas Michael Teausant, who is also a student at San Joaquin Delta Community College in Stockton CA, planned to

Electrical Conductivities of Conductors, Semiconductors, and Their Mixtures at Elevated Temperatures

open access: yesAdvanced Engineering Materials, EarlyView.
This article presents a comprehensive review of temperature‐dependent electrical conductivity data for multiple material classes at elevated temperatures, highlighting a persistent conductivity gap between metals and semiconductors in the range of 102$\left(10\right)^{2}$– 107$\left(10\right)^{7}$ S/m. Metal–ceramic irregular metamaterials are proposed

Cell wall arabinan is essential for guard cell function [PDF]

open access: yes, 2003
Stomatal guard cells play a key role in the ability of plants to survive on dry land, because their movements regulate the exchange of gases and water vapor between the external environment and the interior of the plant.

Role of Histidine‐Containing Peptoids in Accelerating the Kinetics of Calcite Growth

open access: yesAdvanced Functional Materials, EarlyView.
Amphiphilic histidine‐containing peptoids mimic carbonic anhydrase (CA) to accelerate calcite step growth. In the presence of Zn2+, they promote the deprotonation of HCO3−, the desolvation of Ca2+, and the reorganization of interfacial hydration layers, thereby reducing the activation barrier for calcite growth.

Red Light-Induced Phosphorylation of Plasma Membrane H+-ATPase in Stomatal Guard Cells1[OPEN]

open access: yesPlant Physiology, 2018
Red light induces photosynthesis-dependent phosphorylation of plasma membrane H+-ATPase in guard cells to promote stomatal opening in whole leaves. Stomatal opening is stimulated by red and blue light.

PRELIVE: A Framework for Predicting Lipid Nanoparticles In Vivo Efficacy and Reducing Reliance on Animal Testing

open access: yesAdvanced Functional Materials, EarlyView.
PREdicting LNP In Vivo Efficacy (PRELIVE) framework enables the prediction of lipid nanoparticle (LNPs) organ‐specific delivery through dual modeling approaches. Composition‐based models using formulation parameters and protein corona‐based models using biological fingerprints both achieve high predictive accuracy across multiple organs.

Stomatal Opening Involves Polar, Not Radial, Stiffening Of Guard Cells

open access: yesCurrent Biology, 2017
Summary It has long been accepted that differential radial thickening of guard cells plays an important role in the turgor-driven shape changes required for stomatal pore opening to occur [1, 2, 3, 4].

Using Long‐Chain Polymechanophores to Explore the Differences in Mechanoactivation During Nozzle Flow and Ultrasonication

open access: yesAdvanced Functional Materials, EarlyView.
Flow through a nozzle is a common component of most fluid‐based polymer processing techniques such as spray drying, inkjet printing, extrusion. An ultrahigh molecular weight multi‐mechanophore system is used to probe the differences in the distribution of mechanical activation observed between nozzle flow and ultrasonication; the gold standard ...
