Results from the Telescope Array and review of HiRes
A new measurement of the cosmic ray spectrum using the Telescope Array surface arrays is presented. Results on the composition of ultra-high energy cosmic rays from air-fluorescence measurements of shower maximum distributions are presented.

Nanoscale Biodegradable Printing for Designed Tuneability of Vaccine Delivery Kinetics
Spatiotemporal Controlled Release Inks of Biocompatible polyEsters (SCRIBE) is a novel 2PP resin family with sub‐micron resolution and tuneable hydrolysis. SCRIBE enables direct printing of hollow microparticles with complex chemistries and geometries inaccessible to molding techniques, which are used to modulate antibody titers and class switching as ...

Observation of ultra-high energy cosmic rays with the Telescope Array experiment
The origin of ultra-high energy cosmic rays (UHECRs) has been a longstanding mystery. The Telescope Array (TA) is the largest experiment in the northern hemisphere observing UHECR in Utah, USA. It aims to reveal the origin of UHECR by studying the energy

The Parker Instability with Cosmic Ray Streaming [PDF]
Recent studies have found that cosmic ray transport plays an important role in feedback processes such as star formation and the launching of galactic winds. Although cosmic ray buoyancy is widely held to be a destabilizing force in galactic disks, the effect of cosmic ray transport on the stability of stratified systems has yet to be analyzed.

Ultra high energy cosmic ray neutrinos
Abstract Neutrinos, produced by the collisions of ultra high energy cosmic rays and the 3 K background radiation, require careful treatment of the evolving cosmic ray spectrum. The resulting neutrino differential energy spectrum is flat up to energies of order 10 19 eV, thus most events are expected at this energy.

Cosmic Rays: What Gamma Rays Can Say [PDF]
We will review the main channels of gamma ray emission due to the acceleration and propagation of cosmic rays, discussing the cases of both galactic and extra-galactic cosmic rays and their connection with gamma rays observations.

Neutrinos from Gamma Ray Bursts in the IceCube and ARA Era
In this review I discuss the ultra-high energy neutrinos (UHEN) originated from Cosmic-Rays propogation (GZK neutrinos) and from Gamma Ray Bursts (GRBs), and discuss their detectability in kilometers scale detectors like ARA and IceCube.
