Speed Reduction Capabilities of Two-Geometry Roundabouts
Applied Sciences, 2023 Several types of modern roundabouts are alternatives to standard ones. They are either in use or at the development stage today. One such intersection is the two-geometry roundabout.

Mechanical Caging of Nucleic Acids Enabled by Light‐Activated Synthetic Molecular Motors
Angewandte Chemie, EarlyView.A synthetic light‐driven molecular motor imposes mechanical constraints on nucleic acids, enabling “mechanical caging” as a new mode to regulate DNA structure and function through mechanical input rather than chemical masking. ABSTRACT Control over nucleic acid activity is central to biotechnology and therapeutic development.

The Surrogate Safety Appraisal of the Unconventional Elliptical and Turbo Roundabouts
Journal of Advanced Transportation, 2018 Double-lane roundabouts have been created in many European countries over the past few centuries and are now characterized by an unsafe geometric development and by a low sustainability capacity or level.

Effects of Crosswalk Location and Pedestrian Volume on Entry Capacity of Roundabouts
International Journal of Transportation Science and Technology, 2013 At roundabout approaches, vehicles must yield to pedestrians who are using crosswalks. The presence of pedestrians using the crosswalk at a roundabout approach thus decreases the entry capacity of the approach. This research used a calibrated microscopic

Capacity Model for Single-Lane Minor Entry at Turbo-Roundabouts
Civil and Environmental Engineering, 2021 Spirally arranged and physically separated traffic lanes in the circulatory carriageway of turbo-roundabouts force drivers to choose a particular entry lane and, subsequently, a circulatory traffic lane according to their intended destination.

Iterative Selection of DNA Nanostructures for Cellular Uptake
Advanced Materials, EarlyView.DNA nanostructures are promising cell targeting delivery vehicles for therapeutics, but the targeting behavior is not fully understood. In this study, libraries of DNA nanostructures that can be amplified and sequenced are combined with cellular uptake as a selection pressure to iteratively refine DNA structures taken up in cells to better understand ...

Advanced Science, EarlyView.The Gαi1/3 protein is a crucial connecting protein closely related to the signal transduction process of bone formation‐related cytokines such as BMP2. Gαi1/3 mediates downstream signaling pathways such as Smads and MAPK by binding to adaptor proteins like Gab1, thereby promoting the osteogenic effect of BMSCs.

Effect of Signing and Lane Markings on the Safety of a Two-Lane Roundabout [PDF]
, 2014 This report presents a study of the impact lane markings and signing have on driving behavior at a two-lane roundabout located in Richfield, Minnesota. After its completion in 2008, this roundabout sustained a suspiciously high amount of crashes.

BOULE is Essential for the Dynamic Disassembly of Heat Shock Granules in Male Germ Cells
Advanced Science, EarlyView.BOULE orchestrates stress granule disassembly in germ cells via a two‐pronged mechanism: it promotes G3BP1 ubiquitination by upregulating TRIM27, generating a signal for VCP/FAF2 recruitment, and it maintains G3BP1 and FAF2 protein levels. BOULE deficiency disrupts disassembly complex formation, leading to impaired heat shock granule clearance ...
