Small, EarlyView.ABSTRACT Bioactive gold plasmonic nanostructures are enabling non‐invasive saliva diagnostics by amplifying weak Raman signals and converting complex biofluid chemistry into information‐rich spectral fingerprints. This Review examines saliva‐based Raman and surface‐enhanced Raman spectroscopy (SERS) integrated with artificial intelligence (AI) from a ...

High resolution muon tracking with resistive plate chambers [PDF]
, 2012 Following their introduction in the physics community in the early '80s the use of Resistive Plate Chambers (RPCs) as charged particles detectors has constantly increased. Low cost per unit area, good time resolution and easy of operation are some of the

Evolution of the Secondary Electron Spectrum during Cosmic-Ray Discharge in the Universe
The Astrophysical JournalWe recently found that streaming cosmic rays (CRs) induce a resistive electric field that can accelerate secondary electrons produced by CR ionization.

Impact of Atmospheric Profile Variability on Simulated Secondary Cosmic Ray Fluxes Using AtRIS
UniverseWhen high-energy particles of cosmic origin penetrate the atmosphere, they collide with atmospheric atoms and molecules, triggering cascades of secondary particles that can propagate down to the surface.

Solar Cyclic Modulation of Diurnal Variation in Cosmic Ray Intensity
Journal of Astronomy and Space Sciences, 2018 Cosmic rays are ions that move at relativistic speeds. They generate secondary cosmic rays by successive collisions with atmospheric particles, and then, the secondary particles reach the ground.

Cosmic-ray secondary antiprotons - A closer look
The Astrophysical Journal, 1992 An account is given of a course of study encompassing the numerous considerations involved in aircraft gas turbine system definition within an aerothermodynamic framework; these considerations range over engine cycle type, air flowpath design, control integration, inlet and exhaust integration, acoustics, survivability, reliability, and mechanical ...

Unraveling the active site cover of coproheme decarboxylase from Listeria monocytogenes
The FEBS Journal, EarlyView.During heme biosynthesis in Gram‐positive bacteria, coproheme decarboxylase (ChdC) catalyzes the conversion of four‐propionate substrate coproheme to the two propionate product heme b. Its active site is universally covered by a flexible linking loop. This study identifies an important histidine residue, which stabilizes the loop in a ChdC homolog.

High energy cosmic ray air showers and small-x QCD [PDF]
, 2005 We discuss that hadron-induced atmospheric air showers from ultra-high energy cosmic rays are sensitive to QCD interactions at very small momentum fractions x where nonlinear effects should become important.

International Journal of Systematic Theology, EarlyView.Abstract Dionysius's vision of eros as a meeting of reciprocal ecstasies – where lover and beloved each pass out of themselves and into the other – has often been read as unifying dimensions of love otherwise thought to stand in tension, such as giving and receiving.
