Virus-like particle (VLP) technology is a promising approach for the construction of novel vaccines, diagnostic tools, and gene therapy vectors. Initially, VLPs were primarily derived from non-enveloped icosahedral or helical viruses and proved to be viable vaccine candidates due to their effective presentation of epitopes in a native conformation. VLP technology has also been used to prepare c...

GammeV is an experiment conducted at Fermilab that employs the light shining through a wall technique to search for axion-like particles and employs a particle in a jar technique to search for dilaton-like chameleon particles. We obtain limits on the coupling of photons to an axion-like particle that extend previous limits for both scalars and pseudoscalars in the milli-eV mass range. We are ab...

The BHK-21 line of Syrian hamster fibroblasts (1) is used widely for research on viruses and on the neoplastic transformation of cells in vitro. Bernhard and Tournier (2) were the first to describe a virus-like particle in BHK-21 clone 13 (BHK-21/13) cells. Subsequent studies have confirmed the presence of this particle in BHK-2l/ClS/TCG/A (5), BHK-21F (4), and BHK-21/13S (5). A detailed study ...

This work continues our studies of nonlinear evolution of a system of wavepackets. We study a wave propagation governed by a nonlinear system of hyperbolic PDE's with constant coefficients with the initial data being a multi-wavepacket. By definition a general wavepacket has a well defined principal wave vector, and, as we proved in previous works, the nonlinear dynamics preserves systems of wa...

Abstract The generalized SU(2) Proca theory is a vector-tensor modified gravity where the action invariant under both diffeomorphisms and global internal transformations of group. This work constitutes first approach to investigate physical properties at astrophysical scales. We have found solutions that naturally generalize particle-like Einstein-Yang-Mills equations, also known as gauge boson...
