An online national quality assessment survey of prostate MRI reading : interreader variability in prostate volume measurement and PI-RADS classification

Background: High-quality assessment of prostate MRI is fundamental in both clinical practice and screening. There is a lack of national level data on variability in prostate volume measurement and PI-RADS assessment. Methods of quality assurance need to be developed. Methods: All Swedish radiology departments were invited to participate in an external quality assurance of prostate MRI reading. Ten

High prevalence of FAP+ cancer-associated fibroblasts predicts poor outcome in patients with high-grade serous ovarian cancer with high CD8 T-cell density

Objective: Studies have implied that fibroblasts may act as regulators of immune cells in the tumor microenvironment (TME). We investigated the clinical relevance of fibroblast activation protein (FAP) positive stroma in high-grade serous ovarian cancer (HGSC) in relation to CD8+ lymphocyte's infiltration. Methods: In a discovery cohort (N = 113) of HGSC, expression of FAP and CD8 in the TME was a

Dynamical arrest for globular proteins with patchy attractions

Attempts to use colloid science concepts to better understand the dynamic properties of concentrated or crowded protein solutions are challenging due to the fact that globular proteins generally have heterogeneous surfaces that result in anisotropic or patchy contributions to their interaction potential. This is particularly difficult when targeting non-equilibrium transitions such as glass and ge

Antibacterial compounds against non-growing and intracellular bacteria

Slow- and non-growing bacterial populations, along with intracellular pathogens, often evade standard antibacterial treatments and are linked to persistent and recurrent infections. This necessitates the development of therapies specifically targeting nonproliferating bacteria. To identify compounds active against non-growing uropathogenic Escherichia coli (UPEC) we performed a drug-repurposing sc

COMPREHENSIVE SEMICONDUCTOR SCIENCE AND TECHNOLOGY, SECOND EDITION : Volumes 1-3

Semiconductors are at the heart of modern living. Almost everything we do, be it work, travel, communication, or entertainment, all depend on some feature of semiconductor technology. Comprehensive Semiconductor Science and Technology, Second Edition, Three Volume Set captures the breadth of this important field and presents it in a single source to the large audience who study, make, and use semi

Compact, folded multi-pass cells for energy scaling of post-compression

Combining high peak and high average power has long been a key challenge of ultrafast laser technology, crucial for applications such as laser-plasma acceleration and strong-field physics. A promising solution lies in post-compressed ytterbium lasers, but scaling these to high pulse energies presents a major bottleneck. Post-compression techniques, particularly Herriott-type multi-pass cells (MPCs

Sex differences in prevalence and characteristics of imaging-detected atherosclerosis : A population-based study

Aims: Men are more likely to suffer a myocardial infarction than women, but population-based studies on sex differences in imaging-detected atherosclerosis are lacking. The aims were to assess sex differences in the prevalence of imaging-detected coronary and carotid atherosclerosis, as well as multivariable adjusted associations between sex and atherosclerosis. Methods and results: Participants a

Grain size control in quasi-two-dimensional perovskite thin film via intermediate phase engineering for efficient bound exciton generation

Quasi-two dimensional (2D) perovskites have emerged as a promising class of materials due to their remarkable photoluminescence efficiency, which stems from their exceptionally high exciton binding energies. The spatial confinement of excitons within smaller grain sizes could enhance the formation of biexcitons leading to higher radiative recombination efficiency. However, the synthesis of high-qu

Controlled Ligand-Free Growth of Free-Standing CsPbBr3 Perovskite Nanowires

Metal halide perovskite nanowires are widely studied due to their unique electronic and optical characteristics, making them promising for light emitting and detection applications. We developed a ligand-free method to grow vertically aligned free-standing CsPbBr3 nanowires from anodized aluminum oxide nanopore substrates. Here, we investigate the growth process using in situ microscopy with ultra

Effective uniaxial dielectric function tensor and optical phonons in (2 ¯ 01)-oriented β - Ga2 O3 films with equally distributed sixfold-rotation domains

Monoclinic β-Ga2O3 films grown on c-plane sapphire have been shown to exhibit six (2¯01)-oriented domains, which are equally spaced by rotation around the surface normal and equally sized by volume that render the film optical response effectively uniaxial. We derive and discuss an optical model suitable for ellipsometry data analysis of such films. We model mid- and far-infrared ellipsometry data

Nurses’ Work-Related Mental Health in 2017 and 2020: A Comparative Follow-Up Study before and during the COVID-19 Pandemic

The COVID-19 pandemic put a lot of strain on healthcare organizations. Nurses accountfor over 50% of healthcare staff, and how nurses perform in their work is influenced by a number ofhuman and work environmental factors. However, to our knowledge, there has not been a previousstudy with the intention to look at all areas that affect a sustainable working life and how theseimpact nurses’ mental we

The 1356 participatingschool principals in this study were aged between 50 and 64 years of age. Individual and workfactors were evaluated in

Continuous Microwave Photon Counting by Semiconductor-Superconductor Hybrids

We present a continuous microwave photon counter based on superconducting cavity-coupled semiconductor quantum dots. The device utilizes photon-assisted tunneling in a double quantum dot with tunneling events being probed by a third dot. Our device detects both single and multiple-photon absorption events independently, thanks to the energy tunability of a two-level double-dot absorber. We show th

Detection of Very Fast Interface Traps at 4H-SiC/AlN and 4H-SiC/Al2O3 Interfaces

Modest channel carrier mobility in SiC-MOSFETs with NO annealed gate oxides has been the main factor hampering development of low power devices (300 – 650 V). A very fast interface trap, noted as NI, has been suggested to be the main culprit for poor inversion channel carrier mobility. The origin of the NI trap is unknown, but it is likely a property of the SiO2 and it is enhanced during post nitr

Facile In Situ Formation of Potassium Sodium Niobate (KNN) Using The Hexaniobate Polyoxometalate

Lead-based piezoceramics are the dominant materials used in electronic devices, despite the known toxicity of lead. Developing safer piezoelectric materials has inspired the pursuit of lead-free piezoceramics, however some challenges remain in accessing these materials reproducibly. Here we demonstrate a simple and robust method for synthesis of the lead-free piezoceramic material, potassium sodiu

Ultrafast Two-Dimensional Spectroscopy of Photosynthetic Systems

This chapter starts with a review of the theoretical foundation for understanding two-dimensional electronic spectroscopy (2DES) signals in molecular systems. We derive and motivate key properties of 2DES, demonstrating its ability to yield complex information about energy transfer processes and couplings within molecular assemblies, such as photosynthetic antennae. We continue with a discussion e

Surgery Combined with Local Implantation of Doxorubicin-Functionalized Hydroxyapatite Halts Tumor Growth and Prevents Bone Destruction in an Aggressive Osteosarcoma

Osteosarcoma treatment comprises pre-surgical chemotherapy followed by radical surgery and further chemotherapy cycles, but the prognosis has been far from satisfactory. No new drugs or treatment modalities have been developed for clinical use in the last four decades. We describe a nano-hydroxyapatite (HA)-based local drug delivery platform for the delivery of doxorubicin (DOX), a cornerstone dru
