Markov switching negative binomial models: an application to vehicle accident frequencies [PDF]

Accident Analysis and Prevention, 2009, Volume 41, Issue 2, pages 217-226, 2008
In this paper, two-state Markov switching models are proposed to study accident frequencies. These models assume that there are two unobserved states of roadway safety, and that roadway entities (roadway segments) can switch between these states over time.

A Novel Cranial Bone Transport Technique Repairs Skull Defect and Minimizes Brain Injury Outcome in Traumatic Brain Injury Rats

Advanced Science, EarlyView.
This study introduces a novel, safe, and effective surgical technique: Cranial bone transport (CBT) to improve traumatic brain injury (TBI) outcomes in rats. CBT significantly accelerated skull defect bone repair in addition to its promoting effects on neurological function recovery. This work provides an alternative therapy for patients suffering from

Optimizing Polymer Composites for Effective Electromagnetic Shielding: The Role of Carbon Filler Properties and Temperature

Advanced Electronic Materials, EarlyView.
Polymer composites electromagnetic properties are promising for shielding applications. This study explores how filler geometry, orientation, and temperature impact shielding performance. Spherical carbon black enhances scattering, while anisotropic carbon nanotubes (CNTs) show directional wave propagation. CNT orientation critically affects efficiency,
