In imaging, the detection of light originating from multiple scattering, indirect reflections and surrounding backgrounds are known to produce errors especially in intensity-ratio based measurements. SLIPI (Structured Laser Illumination Planar Imaging) is an imaging technique that significantly reduces the impact of such issues. In this study, SLIPI is combined with the two-color LIF (Laser Induce

High-efficiency microfocusing of multi-keV X-rays at synchrotron sources is highly profitable for spatially resolved structural analysis of many kinds. Because radiation from synchrotron sources is typically elongated along the horizontal dimension, generating a microbeam that is isotropic in size requires a carefully designed optics system. Here we report on using a combination of a horizontally

We report on THz time-domain spectroscopy measurements of flux grown KTiOPO4 in the frequency range 0.6–7.0 THz (20 to 240 cm−1). Our results compare well with earlier Raman and far-infrared measurements. We theorize that the differences between the optical phonon mode resonances reported in the literature are due to what growth parameters and melt compositions are used to grow the crystals. We al

Acquisition of entomological data with high-frequency lidar is an emerging research field in rapid development. The technique offers very high numbers of observations per time unit, suitable for statistical models. In this work, we use a near-infrared Scheimpflug lidar with a sampling frequency of 3.5 kHz to assess the activity of free flying organisms. In-situ measurements were done during the ra

This report highlights investigations since 2016 on the Large Igneous Provinces (LIPs), particularly based on their mafic dyke swarms (MDSs) and continental flood basalts (CFBs), from the Indian Shield. Recent research, particularly geochemistry, geochronology and paleomagnetism, allow identification and characterization of distinct generations of LIPs in space and time in the Indian Shield. This

We present a setup for producing and characterizing picosecond ultraviolet laser pulses for use in the MAX IV photocathode electron gun preinjector. Frequency-tripled laser pulses from a commercial laser system are shaped directly in the ultraviolet domain using a Fourier-domain pulse shaper. The pulses were characterized using a transient grating FROG. We discuss a proposed upgrade of the pulse s

I en artikel har Per Ole Träskman diskuterat i vilken utsträckning brottslingen, brottsoffret eller ”jag själv” – det allmänna rättsmedvetandet – bör ges inflytande över kriminalpolitiken. Inspirerad av frågan om kriminalpolitikens nyckelperson riktar jag i den här texten blicken mot två andra aktörer: rättsvetaren och polisen. Först konstaterar jag att rättsvetarens minskade inflytande över krimi

ALICE is one of four large experiments at the CERN Large Hadron Collider near Geneva, specially designed to study particle production in ultra-relativistic heavy-ion collisions. Located 52 meters underground with 28 meters of overburden rock, it has also been used to detect muons produced by cosmic ray interactions in the upper atmosphere. In this paper, we present the multiplicity distribution of

In nanotechnology, fungal mediated green synthesis of silver nanoparticles (AgNPs) has tremendous application in the development of antimicrobial systems but the mechanism behind the synthesis is yet to be understood. This study aims to synthesize the silver nanoparticles via a green chemistry route using mycellial aqueous extract of agriculturally beneficial fungi Trichoderma harzianum. Two diffe

A consistent framework for treating the energy dependence of fission-fragment neutron multiplicities is presented. The shape evolution of the compound nucleus towards scission is treated in the strong damping limit using the Metropolis walk method. The available excitation energy at scission is then divided statistically between the two fragments using microscopic level densities. Deformation ener

In speaking with youth leaders of the Tishreen movement from various cities across the country, what becomes obvious is that while the large lines of national renewal are agreed upon – the need for a new Iraqi identity and new basis for Iraqi nationalism, radical transformation in the practice of power – important points of fracture in their own vision as well as methods for achieving change can b

We consider depletion effects of a pear-shaped colloidal particle in a hard-sphere solvent for two different model realizations of the pear-shaped colloidal particle. The two models are the pear hard Gaussian overlap (PHGO) particles and the hard pears of revolution (HPR). The motivation for this study is to provide a microscopic understanding for the substantially different mesoscopic self-assemb

Within the context of rapid digitalisation of societies, older people increasingly require digital skills to participate civically. However, research has largely overlooked the digital dimension of older adults’ civic participation. Grounding my research in Serrat and colleagues’ (2019) later life civic participation framework, I explored digital content creation and community radio as pathways to

The World Health Organization’s age-friendly city initiative emerged as a response to the intersecting global trends of population ageing and urbanisation. However, a third global trend—digitalisation—has largely been overlooked in research and policy making relating to age-friendly cities and communities. Within the context of a general shift towards online civic participatory activities, this ar

Gaining information of species, temperature, and velocity distributions in turbulent combustion and high-speed reactive flows is challenging, particularly for conducting measurements without influencing the experimental object itself. The use of optical and spectroscopic techniques, and in particular laser-based diagnostics, has shown outstanding abilities for performing non-intrusive in situ diag

The quantizer problem is a tessellation optimization problem where point configurations are identified such that the Voronoi cells minimize the second moment of the volume distribution. While the ground state (optimal state) in 3D is almost certainly the body-centered cubic lattice, disordered and effectively hyperuniform states with energies very close to the ground state exist that result as sta

The Later Life Audio and Radio Co-operative (LLARC) is an England-widenetwork of older content creators, age-inclusive radio stations,third sector organisations, local authorities and academics workingon ageing issues. The co-operative was established in 2019 as anoutcome from a participatory action research project. Aiming topromote talk-based content created by older adults, the LLARCadvocates f
