Ultrafast laser spectroscopy uncovers mechanisms of light energy conversion in photosynthesis and sustainable energy materials

The invention of the laser in 1960 gave us the ruby laser, which generally produced chaotic pulses of light. Six years later, in 1966, a concept called passive mode-locking applied to neodymium-glass lasers produced reasonably well-behaving picosecond pulses. This triggered an intense activity, with respect to developing improved laser pulse sources, measurement techniques, and application to chem

Quantification of [18F]florbetaben amyloid-PET imaging in a mixed memory clinic population : The ABIDE project

Introduction: We investigated amyloid-burden quantification in a mixed memory clinic population. Methods: [18F]Florbetaben amyloid-PET (positron emission tomography) scans of 348 patients were visually read and quantified using the Centiloid (CL) method. General linear models were used to assess CL differences across syndromic and etiological diagnosis. Linear mixed models were fitted to assess th

Toward Biomass-Derived Recyclable Polyesters

Fossil-based plastics have become a matter of concern due to their negative environmental impacts such as greenhouse gas emissions and threats to the health of living beings. Alternative polymers derived from sustainable biomass resources have thus become an attractive research field since the last decade. Currently, there is a strong demand in the development of new bio-based polymers with enhanc

Novel sediment sampling method provides new insights into vertical grain size variability due to marine and aeolian beach processes

In sandy beach systems, the aeolian sediment transport can be governed by the vertical structure of the sediment layers at the bed surface. Here, data collected with a newly developed sand scraper is presented to determine high-resolution vertical grain size variability and how it is affected by marine and aeolian processes. Sediment samples at up to 2 mm vertical resolution down to 50 mm depth we

Metabolically (un)healthy obesity and risk of obesity-related cancers : a pooled study

BACKGROUND: Studies of obesity with or without metabolic aberrations, commonly termed metabolically unhealthy or healthy obesity, in relation to cancer risk are scarce.METHODS: We investigated body mass index (BMI, normal weight/overweight/obesity) jointly and in interaction with metabolic health status in relation to obesity-related cancer risk (n = 23,630) among 797,193 European individuals. A m

Severe, life-threatening, and fatal chronic health conditions after allogeneic blood or marrow transplantation in childhood

Background: A comprehensive assessment of morbidity after allogeneic bone marrow transplantation (BMT) performed in childhood remains understudied. Methods: Seven hundred eighty-nine allogeneic BMT recipients who had survived ≥2 years after BMT performed between 1974 and 2014 at age <22 years and 690 siblings completed a 255-item survey self-reporting sociodemographics and chronic health condition

Guidelines for DC preparation and flow cytometry analysis of mouse nonlymphoid tissues

This article is part of the Dendritic Cell Guidelines article series, which provides a collection of state-of-the-art protocols for the preparation, phenotype analysis by flow cytometry, generation, fluorescence microscopy and functional characterization of mouse and human dendritic cells (DC) from lymphoid organs and various nonlymphoid tissues. DC are sentinels of the immune system present in al

Iterative Calculation of Characteristic Modes Using Arbitrary Full-Wave Solvers

An iterative algorithm is adopted to construct approximate representations of matrices describing the scattering properties of arbitrary objects. The method is based on the implicit evaluation of scattering responses from iteratively generated excitations. The method does not require explicit knowledge of any system matrices (e.g., stiffness or impedance matrices) and is well-suit

Results and plans for nuclear spectroscopy of superheavy nuclei: the Lund perspective

A survey of nuclear structure results obtained along α-decay chains stemming from isotopes of element 114, Fl, and element 115, Mc, is presented. Measures taken to ensure a reliable hand-over of nuclear spectroscopy output to nuclear structure theory are outlined. Possible links between decay chains starting from element 117, Ts, and element 115, Mc, are commented on. The experiments were conducte
