Abstract: This paper introduces a Multi-objective Particle Swarm Optimization (MOPSO) algorithm to address the Transport on Demand Problem (TDP). The dynamic nature of the TDP, which includes ...

Detailed particle morphology supports better assessment of lost circulation materials used in oil and gas drilling to reduce fluid loss risks.

The tiny fatty capsules that delivered COVID-19 mRNA vaccines into billions of arms may work better when they're a little ...

Another theory held that the forces between two particles falls off exponentially in direct relationship to the distance between two particles and that the factor by which it drops is not dependent on ...

A University of Hawaiʻi at Mānoa student-led team has developed a new algorithm to help scientists determine direction in ...

Atmospheric aerosols influence climate forcing, air quality, visibility, and human health, but their properties vary widely across space and time. Satellite instruments equipped with multi-angle and ...

The CMS Collaboration has shown, for the first time, that machine learning can be used to fully reconstruct particle ...

Abstract: This letter deals with the estimation of the refractive index of snowpack based on particle swarm optimization (PSO) algorithm. By leveraging its ability to handle multidimensional ...

Keeping high-power particle accelerators at peak performance requires advanced and precise control systems. For example, the primary research machine at the U.S. Department of Energy's Thomas ...

I peeked in on the house-sized particle detector known as STAR just after it took its last-ever snapshot of one of the most extreme types of fireball ever created. Inside, the conditions just after ...

Mass is what gives particles weight and makes matter behave the way it does. Today’s best theory says particles get their mass from the Higgs field, an invisible feature of space that has been ...

Two papers challenged the existence of theorized particles called sterile neutrinos that might account for mysteries like the cosmos’s dark matter. By Kenneth Chang Just how many types of neutrinos ...
