Continuous agarose beds (monoliths) were prepared by casting agarose emulsions designed to generate superporous agarose. The gel structures obtained were transected by superpores (diameters could be varied in the range 20–200 μm) through which liquids could be pumped. The pore structure and the basic properties of the continuous gel were investigated by microscopy and size exclusion chromatog
Long-term tall-tower eddy-covariance (EC) measurements have been recently established in three European pilot cities as part of the ICOS-Cities project. We conducted a comparison of EC software to ensure a reliable generation of interoperable flux estimates, which is the prerequisite for avoiding methodological biases and improving the comparability of the results. We analyzed datasets covering 5
The initial concept of the electromagnetic elliptical wiggler (EEW) for ELETTRA is a combination of a vertical permanent magnet to generate a wiggler field and a horizontal electromagnet to provide the possibility of switching the helicity of the X-ray radiation. The main aspects of the design of the EEW under construction for ELETTRA are discussed.
By the adoption of the United Nation Convention on the Rights of Personswith Disabilities, many countries have committed to providing conditionsfor persons with disabilities to actively participate in the community. Thisarticle explores the meaning of active citizenship for persons withpsychosocial disabilities and focuses in particular on the role of thestate. Illustrated with examples from Swede
New methods and applications in the separation of biomolecules are reviewed, with an emphasis on the large-scale recovery of proteins. Highlights include the advent of flow-through particles in perfusion chromatography, which allows for very high flow rates, while retaining a high chromatographic efficiency.
Dark-field imaging has been demonstrated to provide complementary information about the unresolved microstructure of the investigated sample. The usual implementation of a grating interferometer, which can provide access to the dark-field signal, consists of linear gratings limiting the sensitivity to only one direction (perpendicular to the grating lines). Recently, a novel grating design, compos
Purpose: This study aimed to investigate the rate of re-ascent requiring re-operation after primary orchidopexy and to investigate eventual differences between the inguinal and scrotal approach as well as other potential predictors for re-ascent. Methods: A retrospective cohort study of children treated for undescended testis (UDT) with orchidopexy between 2018 and 2022 was conducted. The primary
A model for the interpretation of nystagmus is worked out. A lesion in the vestibular system may appear as alteration in velocity of slow viz. fast phase of nystagmus, disconjugation of the nystagmus or as dysrhythmic nystagmus. The visual system, viz. the cortical and subcortical optokinetic nystagmus seems to provide the eye-head coordinates and retical error velocity to calibrate or cancel the
Can the right requirements boost developer satisfaction and happiness? We believe they can. In keeping with this issue's theme, 'Well-Being for Resilience: Developers Thrive,' we discuss the connection between the three keywords, well-being, resilience, and thriving. How could requirements engineering foster these qualities? While there hasn't been much research on this topic, we see opportunities
Time-domain spectroscopy encompasses a wide range of techniques, such as Fourier-transform infrared, pump-probe, Fourier-transform Raman, and two-dimensional electronic spectroscopies. These methods enable various applications, such as molecule characterization, excited state dynamics studies, or spectral classification. Typically, these techniques rarely use sampling schemes that exploit the prio
Functional data analysis is typically performed in two steps: first, functionally representing discrete observations, and then applying functional methods to the so-represented data. The initial choice of a functional representation may have a significant impact on the second phase of the analysis, as shown in recent research, where data-driven spline bases outperformed the predefined rigid choice
Incorporating fused benzene rings in backbones of anion conducting polymers may improve the properties of anion exchange membranes (AEMs). Here, we haveprepared and studied ether-free AEMs based on poly(arylene piperidinium)s containing up to 50% phenanthrene units. A series of terpolymers were prepared in superacid-mediated polyhydroxyalkylations of phenanthrene, p-terphenyl and N-methylpiperidon
In December 1998 the FRN - The Swedish Council for Planning and Coordination of Research - decided to fund a new injector and storage ring for the MAX-laboratory. The system will consist of a 50-MeV linac, a 600-MeV booster synchrotron, and a 600-MeV storage ring for VUV undulator beamlines. The system will replace an old 100-MeV racetrack microtron and will inject the two existing storage rings:
Machine Learning (ML) algorithms are generally designed for scenarios in which all data is stored in one data center, where the training is performed. However, in many applications, e.g., in the healthcare domain, the training data is distributed among several entities, e.g., different hospitals or patients’ mobile devices/sensors. At the same time, transferring the data to a central location for
