pH dependence of aqueous oxalic acid observed by X-ray absorption and emission spectroscopy
In this work, X-ray absorption spectroscopy (XAS) and site-selective X-ray emission spectroscopy (XES) were used to measure the oxygen K-edge (OC=O,1s and OCO − ,1s) of oxalic acid, with theoretical calculations performed to reproduce the spectra observed. Structure sampling of a cluster model was performed using an ab initio molecular dynamics trajectory. Relative XES intensities from core-hole e
Tomographic reconstruction with a generative adversarial network
This paper presents a deep learning algorithm for tomographic reconstruction (GANrec). The algorithm uses a generative adversarial network (GAN) to solve the inverse of the Radon transform directly. It works for independent sinograms without additional training steps. The GAN has been developed to fit the input sinogram with the model sinogram generated from the predicted reconstruction. Good qual
Two routes for extracellular electron transfer in Enterococcus faecalis
Enterococcus faecalis cells are known to have ferric reductase activity and the ability to transfer electrons generated in metabolism to the external environment. We have isolated mutants defective in ferric reductase activity and studied their electron transfer properties to electrodes mediated by ferric ions and an osmium complex modified redox polymer (OsRP), respectively. Electron transfer med
Breakdown of Whole-brain Dynamics in Preterm-born Children
The brain operates at a critical point that is balanced between order and disorder. Even during rest, unstable periods of random behavior are interspersed with stable periods of balanced activity patterns that support optimal information processing. Being born preterm may cause deviations from this normal pattern of development. We compared 33 extremely preterm (EPT) children born at < 27 weeks of
Non-ambulatory children with cerebral palsy : effects of four months of static and dynamic standing exercise on passive range of motion and spasticity in the hip
Purpose: The aim of this study was to compare the effects of four months of two types of structured training regimes, static standing (StS) versus dynamic standing (DyS), on passive range of motion (PROM) and spasticity in the hip among non-ambulatory children with cerebral palsy.Method: Twenty non-ambulatory children with cerebral palsy participated in an exercise intervention study with a crosso
A sustainable working life for all ages – The swAge-model
Background: Due to the demographic challenge in most countries it is important to consider making work life sustainable. A sustainable work life is of importance in all age groups when working life will be extended to a higher age. Aim: Towards a theoretical model with an impact on a sustainable working life for all ages, the swAge - model. Method: The theoretical model, the swAge-model, is develo
Diverting blame to stay sane - Young people's strategies for dealing with the mental health effects of precarious employment : A grounded theory study
Background: Precarious employment is a risk factor for poor mental health, particularly among young adults. Knowledge about how young people maintain their mental health while in a precarious employment situation is scarce. The aim of the study was to explore the meaning of precarious employment for young adults in Sweden and their strategies for maintaining good mental health. Methods: In-depth i
Introduction : Candidates between parties and voters-A triadic relationship in the belgian partitocracy
The introductory chapter emphasises the general relevance of the study of electoral candidates in representative democracies. It presents the book’s theoretical framework: the triadic delegation and accountability relationship between candidates, voters and parties—based on principal–agent theory. We theoretically map patterns of candidates’ behaviour and attitudes in all main dimensions of their

Heterologous Expression of the Barley (Hordeum vulgare L.) Xantha-f, -g and -h Genes that Encode Magnesium Chelatase Subunits
Biosynthesis of chlorophyll involves several enzymatic reactions of which many are shared with the heme biosynthesis pathway. Magnesium chelatase is the first specific enzyme in the chlorophyll pathway. It catalyzes the formation of Mg-protoporphyrin IX from the insertion of Mg2+ into protoporphyrin IX. The enzyme consists of three subunits encoded by three genes. The three genes are named Xantha-
Laplace–Carleson Embeddings on Model Spaces and Boundedness of Truncated Hankel and Toeplitz Operators
A characterisation is given of bounded embeddings from weighted L2 spaces on bounded intervals into L2 spaces on the half-plane, induced by isomorphisms given by the Laplace transform onto weighted Hardy and Bergman spaces (Zen spaces). As an application necessary and sufficient conditions are given for the boundedness of truncated Hankel and Toeplitz integral operators, including the weighted cas
A novel biomarker of MMP-cleaved prolargin is elevated in patients with psoriatic arthritis
Psoriatic arthritis (PsA) is a chronic musculoskeletal inflammatory disease found in up to 30% of psoriasis patients. Prolargin—an extracellular matrix (ECM) protein present in cartilage and tendon—has been previously shown elevated in serum of patients with psoriasis. ECM protein fragments can reflect tissue turnover and pathological changes; thus, this study aimed to develop, validate and charac
A finite element analysis (FEA) approach to simulate the coefficient of friction of a brake system starting from material friction characterization
The coefficient of friction (COF) is one of the most important parameters to evaluate the performance of a brake system. To design proper brake systems, it is important to know the COF when estimating the brake force and resulting torque. It is challenging to simulate the COF since friction in disc brakes is a complex phenomenon that depends on several parameters such as sliding velocity, contact
More than Anti-communism : Electoral Politics and the Meanings of Democracy in Taiwan
Governments across anti-communist Asia, with US backing or tacit consent, devised institutions and practices for marginalising popular forces. Such internalisation of the Cold War involved measures ranging from violence and ideological mobilisation to disciplinary modes of control. With democratisation, Cold War devices for domestic control could remain entrenched or be rolled back. Examining the
Electrochemical Fabrication and Characterization of Palladium Nanowires in Nanoporous Alumina Templates
A method for the electrochemical synthesis of palladium nanowires, using porous alumina templates with diameters of 25 nm and 40 nm, is presented. Through an electrochemical barrier layer thinning step, pulsed electrodeposition can take place directly into the anodized aluminum; without need for extra removal, pore opening, and metal contact coating steps. A digital oscilloscope is used to record
