Magnetic field amplification and electron acceleration by a mildly relativist...Gareth Murphy
The document summarizes the results of a particle-in-cell simulation of a mildly relativistic quasi-parallel shock. The simulation shows:
1) Filamentation of ions at the shock front and magnetic field amplification beyond compression alone.
2) Electrons are accelerated nearly to equipartition with ions, reaching gamma factors of around 100.
3) Magnetic bubbles and peaks in magnetic pressure form downstream of the shock, driven by drift currents and gradient-B electric fields.
The results suggest that significant synchrotron radiation could be produced by electrons accelerated in such relativistic shocks. Further simulations are planned to study transient shocks and fully 3D effects.
Effect of electric field on filamentation in counterstreaming beamsGareth Murphy
1) A simulation study compared the filamentation instability in an electron-positron plasma versus an electron plasma with fixed ions.
2) The electron-positron plasma showed weaker electrostatic field growth and larger voids between filaments in the final stages.
3) While the magnetic energy saturation level was unchanged, the magnetic pressure gradient force led to differences in filament size, separation, and filling factor between the two cases.
Linear Programming and its Usage in Approximation Algorithms for NP Hard Opti...Reza Rahimi
The document provides an overview of linear programming and its usage in approximation algorithms for NP-hard optimization problems. It discusses linear programming formulations, the complexity classes P and NP, approximation algorithms, and two case studies on the minimum weight vertex cover problem and the MAXSAT problem. Randomized rounding techniques are used to generate approximation algorithms for these problems from their linear programming relaxations.
The Ordovician Period saw the rapid evolution and diversification of many new types of invertebrate animals, including trilobites, brachiopods, and bryozoans. Primitive plants began to colonize land for the first time, while fungi formed mutualistic relationships with plant roots. The period ended in a major extinction event.

Los ovarios son glándulas reproductoras femeninas que secretan hormonas y producen óvulos. Juegan un papel clave en el desarrollo de los órganos reproductores femeninos, la preparación del útero para la implantación del óvulo y el desarrollo de las glándulas mamarias. Problemas en los ovarios pueden causar deficiencias hormonales que alteran el ciclo menstrual y la fertilidad de la mujer.

This document provides an overview of the gameplay for Super Mario Bros. X, a fan-made Mario game. It discusses the system requirements, controls, screen layout, playable characters like Mario, Luigi and Link, common items like mushrooms and fire flowers, and major enemies like Birdo, Mouser and Bowser. The manual was created by community member "Blue" and provides details on character abilities, item effects, and boss battle strategies to help players experience and enjoy the fan game.
Aunt Martha's is a non-profit organization that provides various social services to families and youth in the Chicago area. It began in 1972 serving troubled youth and has since expanded to 17 health centers serving over 80,000 people annually. Services include primary healthcare, dental care, behavioral health, child welfare, juvenile justice programs, and women's health services. Aunt Martha's aims to provide a caring community for those in need.
The document outlines the marketing strategy for the film Starstruck. It discusses using various forms of advertising like trailers and posters. It also discusses generating publicity through press kits, interviews, and film festival screenings. Tie-ins with companies like competitions and soundtracks are mentioned. The strategy focuses heavily on viral marketing using social media, websites, apps, and video leaks to generate buzz among the target audience. Both traditional above the line advertising paid for by the distributor and below the line unpaid publicity tactics are covered.
