mPE

MPE is an acronym used in several different fields, and its meaning depends on the context. This article outlines several widely used interpretations.

Malignant pleural effusion (MPE) is a medical condition characterized by the accumulation of fluid in the pleural space due to cancer or other diseases. It can cause shortness of breath and chest discomfort. Diagnosis typically involves imaging and thoracentesis with fluid analysis. Treatments focus on relieving symptoms and may include drainage, pleurodesis, or systemic therapy for the underlying cancer.

Multi-Programming Executive (MPE) refers to the operating system developed by Hewlett-Packard for the HP 3000 family of minicomputers. MPE supported batch and interactive processing and included integrated database capabilities. Over its lifetime, it evolved through variants such as MPE XL and MPE/iX, the latter incorporating POSIX compatibility to run some UNIX-like software. The MPE family was associated with business data processing on HP 3000 systems.

Max Planck Institute for Extraterrestrial Physics (MPE) is a German research institution located in Garching near Munich. It is part of the Max Planck Society and conducts research in high-energy astrophysics, X-ray and gamma-ray astronomy, and related observational and theoretical work. The institute collaborates internationally on space missions and ground-based studies.

Minimum potential energy (MPE) is a principle in physics and engineering stating that, among all possible configurations under given constraints, a stable equilibrium corresponds to a state of minimum potential energy. The concept underpins analyses in structural mechanics, elasticity, and variational methods.
