Exploring the Effectiveness of Transit Security Awareness Campaigns in the San Francisco Bay Area, Research Report 09-19 [PDF]

open access: yes, 2010
Public involvement in alerting officials of suspicious and potentially harmful activity is critical to the overall security of a transit system. As part of an effort to get passengers and the public involved, many transit agencies have security awareness

Microscale Mapping of Fiber Strain and Damage in Composite Wrinkled Laminates Using Computed Tomography Assisted Wide‐Angle X‐Ray Scattering

open access: yesAdvanced Science, EarlyView.
This study combines full‐field tomography with diffraction mapping to quantify radial (ε002$\varepsilon _{002}$) and axial (ε100$\varepsilon _{100}$) lattice strain in wrinkled carbon‐fiber specimens for the first time. Radial microstrain gradients (−14.5 µεMPa$\varepsilon \mathrm{MPa}$−1) are found to signal damage‐prone zones ahead of failure, which ...

Comparative efficacy of different exercise interventions in patients with ankylosing spondylitis: a systematic review and network meta-analysis [PDF]

open access: yesPeerJ
Background Exercise interventions have been widely applied as an adjunctive treatment for ankylosing spondylitis (AS), effectively alleviating pain, improving function, and enhancing quality of life. However, the efficacy of different exercise modalities

Approximation Algorithms for Campaign Management [PDF]

open access: yes, 2010
We study electoral campaign management scenarios in which an external party can buy votes, i.e., pay the voters to promote its preferred candidate in their preference rankings. The external party's goal is to make its preferred candidate a winner while paying as little as possible.

Gravity‐Tolerant In‐Flight 3D Bioprinting Enabled by Stereolithography for Space Tissue Engineering

open access: yesAdvanced Science, EarlyView.
A flight‐compliant, closed stereolithographic 3D bioprinting system enables robust fabrication of acellular and cell‐laden hydrogel constructs under varying gravitational conditions, including microgravity and hypergravity phases. Printed structures retain dimensional fidelity and high‐resolution features, while cell viability remains high ...

Ubiquitination‐Driven Reprogramming of Proteostasis in Metastasis

open access: yesAdvanced Science, EarlyView.
The DCAF12–TRiC/CCT axis is a key regulator of metastasis in cancer. By reprogramming proteostasis to ensure efficient protein folding, it drives progression through a dual mechanism: enhancing cancer cell motility and invasiveness while concurrently activating pro‐growth and survival pathways.

Spatial Control Over Tether‐Tunable Coordination on Palladium for Divergent Synthesis of Bicyclo[n.1.0]alkanes via Oxidative Cyclopropanation of Enynes

open access: yesAdvanced Science, EarlyView.
We have developed a Pd‐catalyzed oxidative cyclopropanation of 1,n‐enynes employing cyclic diacyl peroxides as bifunctional reagents that serve as both tether‐tunable oxidants and spatially controlled dicarboxylate anions. ABSTRACT Bicyclo[n.1.0]alkanes are highly valuable scaffolds in drug discovery and synthetic chemistry.
