The gas in scattering media absorption spectroscopy (GASMAS) technique was used to investigate the possible presence of free gas pores in human condyle bones, extracted from the tibia in knee revision surgical procedures in response to arthrosis development. Following earlier studies showing free gas presence in femoral head bones, decaying because of inadequate blood flow, we investigated condyle

There is a strong desire for short wavelength (~1 Å), short pulsewidth (<100 fs), high-brightness, transverse and longitudinally coherent light pulses for use by the synchrotron radiation community. These requirements exceed the limits achievable by existing, so-called, "third-generation" light sources, such as the Advanced Photon Source (APS) at Argonne National Laboratory (ANL), USA, the Europea

We present results on a 404 nm laser system based on second harmonic generation in a new compact external cavity configuration. We obtain a stable 318 mW cw diffraction limited output from the system with a mode-matched pump power of 630 mW. We observe up to 620 mW SHG, when the cavity is operating in scanning mode. The pump source is an external cavity grating feedback tapered diode laser operati

Aim: The role of islet nitric oxide (NO) production in insulin releasing mechanisms is unclear. We examined whether the beneficial effects of the imidazoline derivative RX 871024 (RX) on beta-cell function might be related to perturbations of islet NO production. Methods: Experiments were performed with isolated islets or intact mice challenged with glucose or carbachol with or without RX treatmen

Forskningen inom avdelningen för Elektromagnetism och Nanoelektronik spänner över ett bredd områden från teoretisk elektroteknik och vågutbredning till nanoelektroniska komponenter och system. Tematiskt är forskningsområden indelade i 6 områden: Antenner och vågor, Metamaterial, Nanoelektronik för IoT, neuromorfa elektronik, kvantteknologi, THz och Kraftelektronik. Inom elektromagnetismen läggs s

In this work, we use a novel spectral polarimetric optical tomographic imaging goniometer (SPOTIG) to investigate the scattering properties of Anopheles malaria mosquitoes to aid in their detection and identification in entomological lidar applications. Mosquitoes were mounted on a turn table, on which they were illuminated from different angles with linearly polarized near infrared light and rota

The chirality-flow formalism, combined with good choices of gauge reference vectors, simplifies tree-level calculations to the extent that it is often possible to write down amplitudes corresponding to Feynman diagrams immediately. It has also proven to give a very sizable speedup in a proof of concept implementation of massless tree-level QED in MadGraph5_aMC@NLO. In the present paper we extend t
