Summary
This study presents a new method to link energy system changes to air quality impacts. It helps evaluate policies by modeling future emissions and their effects on air quality using the TIMES and CMAQ models.
Area of Science:
- Environmental Science
- Energy Systems Analysis
- Atmospheric Chemistry
Background:
- Assessing policy impacts on air quality requires understanding the link between emissions and air quality.
- The energy system significantly influences emissions, which in turn affect air quality.
Purpose of the Study:
- To introduce a methodology for assessing air quality impacts resulting from changes in the energy system.
- To provide a framework for evaluating the air quality effects of specific energy policies and technological shifts.
Main Methods:
- Developed diverse scenarios for the US energy system evolution using the TIMES (The Integrated MARKAL-EFOM System) energy system model.
- Utilized an R script to transfer emissions data from TIMES scenarios to the CMAQ (Community Multiscale Air Quality) photochemical model.
- Demonstrated example results and described scenario development for broader applicability.
Main Results:
- The methodology successfully connects energy system scenarios to air quality outcomes.
- Example results illustrate the potential air quality impacts of different energy system futures.
- The developed TIMES scenarios are adaptable for use in other geographic regions.
Conclusions:
- The introduced methodology provides a valuable tool for air quality impact assessment related to energy system changes.
- This approach can inform policy decisions by quantifying air quality benefits of emissions reduction measures and technological advancements.
- The framework supports the evaluation of broad energy sector transformations on air quality.

Drug transporters are critical in drug absorption, distribution, and excretion processes. They should be included in physiological-based pharmacokinetic (PBPK) models, which help predict human drug disposition. However, predicting this is challenging during drug development, especially when liver transport is involved. However, with a realistic representation of body transport processes, an accurate model may be possible.

Mechanistic models, a category encompassing both physiological and compartmental modeling, differ from empirical models' approaches to incorporating known factors about the systems being modeled. Empirical models describe data with minimal assumptions, while mechanistic models aim to provide a robust description of available data by specifying assumptions and integrating known factors about the system. Compartmental analysis is a key example of a mechanistic model in pharmacokinetics and...

Gas exchange, the intake of molecular oxygen (O2) from the environment and the outflow of carbon dioxide (CO2) into the environment, is necessary for cellular function. Gas exchange during respiration occurs largely via the movement of gas molecules along pressure gradients. Gas travels from areas of higher partial pressure to areas of lower partial pressure. In mammals, gas exchange occurs in the alveoli of the lungs, which are adjacent to capillaries and share a membrane with them.

Physiological and compartmental models are valuable tools used in studying biological systems. These models rely on differential equations to maintain mass balance within the system, ensuring an accurate representation of the dynamic processes at play.
Physiological models take a detailed approach by considering specific molecular processes. They can predict drug distribution, metabolism, and elimination changes, providing a comprehensive understanding of how drugs interact with the body.
