Tramadol Co‐Administration with Oxycodone or Hydrocodone Increases Opioid Burden without Improving Postoperative Pain Control

Tramadol is frequently co-prescribed with oxycodone or hydrocodone after surgery under the assumption that its dual mechanism of action provides an opioid-sparing benefit. However, evidence supporting this practice is limited and inconsistent. We conducted a secondary analysis of...

Establishment of Passenger Car Equivalent (PCE) Values for Urban Intersections Using Drones

Passenger Car Equivalent (PCE) factors are widely used to convert heterogeneous traffic streams into equivalent homogeneous flow rates for the design and analysis of roads and intersections. In developing countries, mixed traffic conditions differ substantially from those in deve...

A task-aligned multimodal machine learning framework for studying working memory dysfunction in Parkinson’s disease

<title>Abstract</title> Cognitive impairment is one of the most functionally debilitating non-motor symptoms in Parkinson's disease (PD). Yet, current diagnostic and clinical practices rely heavily on subjective assessments and burdensome behavioral testing, which lack the tempor...

Prompt Engineering of Large Language Models for Medication Dose Calculation

This study aims to design and validate a large language model (LLM) framework for systematic extraction of medication dosing across multiple therapeutic classes using electronic health record (EHR) data. Manual dose annotations were completed for 4295 medications across nine ther...

First-principles identification of optically efficient erbium centers in GaAs

Gallium arsenide (GaAs) doped with erbium (Er), a material of interest for optoelectronics and quantum information, has been studied for decades. Yet the formation of Er luminescence centers in the semiconductor host and their properties are still not well understood. Here we pre...
