Relativistic spin sum rules and the role of the pivot
European Physical Journal C: Particles and Fields, 2021 Spin sum rules depend on the choice of a pivot, i.e. the point about which the angular momentum is defined, usually identified with the center of the nucleon.

Kansas Center Pivot Uniformity Evaluation Overview
Applied Engineering in Agriculture, 2019 Abstract. Center pivot irrigation systems are the most common system type in Kansas for a variety of factors – one of which is the ability to deliver a uniform depth of water application for a variety of crops and field conditions. Uniform applications are dependent on properly designed, installed and operated sprinkler nozzle packages.

Egyptian Journal of Remote Sensing and Space Sciences, 2017 Traditional methods for center pivot evaluation depend on the water depth distribution along the pivot arm. Estimation and mapping the water depth under pivot irrigation systems using remote sensing data is essential for calculating the coefficient of ...

Selection of end gun and optimization of water distribution under a center pivot irrigation system
Agricultural Water ManagementWhen a center pivot irrigation system is adopted in a square field, its four corners cannot be irrigated. Therefore, an end gun is often installed at the end of the system to expand the irrigated area; as such, proper selection of the end gun and ...

Reciprocal control of viral infection and phosphoinositide dynamics
FEBS Letters, EarlyView.Phosphoinositides, although scarce, regulate key cellular processes, including membrane dynamics and signaling. Viruses exploit these lipids to support their entry, replication, assembly, and egress. The central role of phosphoinositides in infection highlights phosphoinositide metabolism as a promising antiviral target.
