A momentum resolved resonant inelastic X-ray scattering (qRIXS) experimental station with continuously rotatable spectrometers and parallel detection is designed to operate at different beamlines at synchrotron and free electron laser (FEL) facilities. This endstation, currently located at the Advanced Light Source (ALS), has five emission ports on the experimental chamber for mounting the high-th
Rationale: Cerebrovascular diseases associated with pregnancy and postpartum period are uncommon; however, they can have an important impact on health of both women and foetus or newborn. Aims: To evaluate the frequency, characteristics and management of cerebrovascular events in pregnant/postpartum women, to clarify pathophysiological mechanisms underlying the occurrence of these events including
Purpose: TRPM1-associated congenital stationary night blindness (CSNB) is characterized by nystagmus and high myopia. We assessed retinal function and structure over long-term follow-up up to 10 years in two siblings from a family with the homozygous deletion c.2394delC in exon 18 that we previously identified. In addition, we describe retinal function and structure in two other siblings with the
Massive multiple-input multiple-output (MIMO) arrays are becoming critical elements in cellular base station infrastructure. We utilize the theory of characteristic modes (TCM) to design a novel tri-modal broadside antenna element which is suitable for the construction of compact massive MIMOarrays. The proposed antenna element consists of three ports which is formed by reviewing an existing compa
Background: Pituitary adenylate cyclase-activating polypeptide (PACAP) occurs as either a 27- or 38-amino acid neuropeptide and belongs to the vasoactive intestinal polypeptide/glucagon/secretin family of peptides. PACAP and vasoactive intestinal polypeptide have a 68% homology of their amino acid sequences and share three B-type G-protein coupled receptors: VPAC1, VPAC2 and PAC1 receptors. Method
Objective: To assess the long-term results of elective abdominal aortic aneurysm (AAA) repair with a single stent graft system. Methods: Patients undergoing elective, infrarenal endovascular aneurysm repair (EVAR) with a single-stent graft system between 1998 and 2012 were analyzed retrospectively registering pre-, intra-, and postoperative data. All imaging was reviewed. Data are presented as med
The study describes the first glycoside hydrolase that exhibits comparable levels of activity on α- and β-linked saccharide substrates. This enzyme, assigned into GH109, is encoded by the genome of the human gut symbiont Akkermansia muciniphila that is a model primary degrader of the heavily O-glycosylated mucin glycoprotein that coats the epithelial enterocytes.The elusive catalytic acid/base cat
Light-to-electricity conversion processes in organic and dye sensitized solar cells have attracted much scientific effort, aiming to understand the fundamental nature of these processes and to improve solar cell efficiency. Power conversion efficiency of such solar cells has progressed steadily in the last few decades, suggesting applicability for commercial products in the nearest future. Yet, th
More than a century ago, the centrosome was discovered and described as “the true division organ of the cell”. Electron microscopy revealed that a centrosome is an amorphous structure or pericentriolar protein matrix that surrounds a pair of well-organized centrioles. Today, the importance of the centrosome as a microtubule-organizing center and coordinator of the mitotic spindle is questioned, be
Aim: Investigate the feasibility of identifying a well-defined treatment group and a comparable reference group in clinical register data. Background: There is insufficient knowledge on how to avert neck/back pain from turning chronic or to impair work ability. The Swedish Government implemented a national multimodal rehabilitation (MMR) programme in primary care intending to promote work ability,
Ambiguous figures, as described in visual perceptual psychology, are single pictures that contain several possible, mutually exclusive, motifs. Some specific cases of images in South Scandinavian Bronze Age rock art can be fruitfully analysed as ambiguous figures. Furthermore, we argue that these images represent some sort of narrativity, which needs to be understood in order to make a perceptual
In this paper we argue for a developmental perspective in language assessment of second language learning, and that there is a need for an assessment with clear and precise criteria for evaluating the grammatical levels. Processability Theory is suggested as a theoretical framework for a stage model that enables teachers to follow the second language development over time. We have tested this appr
