A Proposal of a Renormalization Group Transformation for Lattice Field Theories [PDF]

, 1994
We propose a new Real Space Renormalization Group transformation useful for Monte Carlo calculations in theories with global or local symmetries. From relaxation arguments we define the block-spin transformation with two tunable free parameters, adapted ...

Machine learning framework to predict pharmacokinetic profile of small molecule drugs based on chemical structure

Clinical and Translational Science
Accurate prediction of a new compound's pharmacokinetic (PK) profile is pivotal for the success of drug discovery programs. An initial assessment of PK in preclinical species and humans is typically performed through allometric scaling and mathematical ...

A technology-based global non-methane volatile organic compounds (NMVOC) emission inventory under the MEIC framework [PDF]

Atmospheric Chemistry and Physics
Non-methane volatile organic compounds (NMVOC) play a crucial role in tropospheric atmospheric chemistry. Developing accurate NMVOC emission inventories is essential for chemical transport modeling and pollution mitigation.

A globally convergent matricial algorithm for multivariate spectral estimation

, 2008
In this paper, we first describe a matricial Newton-type algorithm designed to solve the multivariable spectrum approximation problem. We then prove its global convergence.

The Aggravation of Summertime Nocturnal Ozone Pollution in China and Its Potential Impact on the Trend of Nitrate Aerosols

Geophysical Research Letters, 2023
Tropospheric ozone (O3) concentration continued to increase over past years, thereby becoming a growing environmental concern in China. Most studies have focused on the analysis of daily maximum 8‐hr O3 concentration, while there is still a dearth of ...
