Impact of velocity- and acceleration-compensated encodings on signal dropout and black-blood state in diffusion-weighted magnetic resonance liver imaging at clinical TEs
Purpose The study aims to develop easy-to-implement concomitant field-compensated gradient waveforms with varying velocity-weighting (M1) and acceleration-weighting (M2) levels and to evaluate their efficacy in correcting signal dropouts and preserving the black-blood state in liver diffusion-weighted imaging. Additionally, we seek to determine an optimal degree of compensation that minimizes sign
Automatic time-frequency analysis of echolocation signals using the matched Gaussian multitaper spectrogram
High-resolution time-frequency (TF) images of multi-component signals are of great interest for visualization, feature extraction and estimation. The matched Gaussian multitaper spectrogram has been proposed to optimally resolve multi-component transient functions of Gaussian shape. Hermite functions are used as multitapers and the weights of the different spectrogram functions are optimized. For
The role of T cells and myeloid-derived suppressor cells in refractory immune thrombocytopenia
Immune thrombocytopenia (ITP) is characterized by a dysregulated immune response against platelets, affecting both their destruction and production. A role for an abnormal T-cell compartment has been established in ITP pathogenesis and treatments that increase platelet counts in patients with ITP have shown improvements in T-cell profiles. On the other hand, patients who were refractory to treatme
Discordance Between Creatinine-Based and Cystatin C–Based Estimated GFR : Interpretation According to Performance Compared to Measured GFR
Rationale & Objective: Use of cystatin C in addition to creatinine to estimate glomerular filtration rate (estimated glomerular filtration rate based on cystatin C [eGFRcys] and estimated glomerular filtration rate based on creatinine [eGFRcr], respectively) is increasing. When eGFRcr and eGFRcys are discordant, it is not known which is more accurate, leading to uncertainty in clinical decisio
Research bricolage on far-right metapolitics: Superordinate intersectionality perspectives on digital identities
This article is a reaction to previous appeals to widen the conceptual remit of Critical Discourse Studies (CDS). It proposes research bricolage as means for critical engagement with conceptual constructs originating from adjacent social science disciplines. Borrowing such concepts as far-right metapolitics from political science, superordinate intersectionality from gender studies, and Web 2.0 so

Interim Report on Gribshunden (1495) Excavations: 2019–2021
We present an interim archaeological report on the ship- wreck of the Danish-Norwegian flagship Gribshunden. Built in 1485, extensively employed by King Hans as his floating castle, and ultimately lost in June 1495 en route to Kalmar, the ship carried people and material selected to further the political goal of re-unifying the Nordic region. Three field campaigns led by Lund University and Blekin

Proteomic analysis shows decreased type I fibers and ectopic fat accumulation in skeletal muscle from women with PCOS
Background: Polycystic ovary syndrome's (PCOS) main feature is hyperandrogenism, which is linked to a higher risk of metabolic disorders. Gene expression analyses in adipose tissue and skeletal muscle reveal dysregulated metabolic pathways in women with PCOS, but these differences do not necessarily lead to changes in protein levels and biological function. Methods: To advance our understanding of

Symptoms during pregnancy in primiparous women with congenital heart disease
Background: As more women with congenital heart disease (CHD) are reaching childbearing age, it becomes more common for their symptoms to be evaluated during pregnancy. However, pregnancy-related symptoms are similar to those caused by heart disease. This study investigated the prevalence of factors associated with symptoms during pregnancy in women with CHD. Methods: The national birth register w

Low-power Acceleration of Convolutional Neural Networks using Near Memory Computing on a RISC-V SoC
The recent peak in interest for artificial intelligence, partly fueled by languagemodels such as ChatGPT, is pushing the demand for machine learning and dataprocessing in everyday applications, such as self-driving cars, where low latency iscrucial and typically achieved through edge computing. The vast amount of dataprocessing required intensifies the existing performance bottleneck of the datamo
Parity-conserving Cooper-pair transport and ideal superconducting diode in planar germanium
Superconductor/semiconductor hybrid devices have attracted increasing interest in the past years. Superconducting electronics aims to complement semiconductor technology, while hybrid architectures are at the forefront of new ideas such as topological superconductivity and protected qubits. In this work, we engineer the induced superconductivity in two-dimensional germanium hole gas by varying the
