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

Evaluating the effectiveness of the ‘eco-cooler’ for passive home cooling

Constructed with used plastic bottles, the eco-cooler has been widely adopted in resource-poor communities in Bangladesh and other countries. We tested the eco-cooler under controlled conditions using a scientific wind tunnel in a climatic chamber. In our tests, we used seven eco-cooler designs in 27 climate conditions typical of Bangladesh (temperatures of 40 °C, 35 °C, and 30 °C; humidity levels

Textbook of von Willebrand Disease : Basic and Clinical Aspects

Comprehensive resource summarizing recent research on von Willebrand disease, showing clinicians how to optimize management of patients with this disorder The newly revised and updated second edition of Textbook of von Willebrand Disease: Basic and Clinical Aspects, 2nd edition describes the important and complex role of von Willebrand factor (VWF) in hemostasis and thrombosis, covering not only t

Social workers’ experiential accounts of complex intervention development for youth and families in practice settings

We aimed to explore social workers’ experiential accounts of developing complex interventions for youth and families within practice settings. Social workers’ experience of developing interventions has not been leveraged in scientific research even though many complex interventions in use are developed by social workers in practice settings. Lack of insight into the intervention development proces

Bias and precision of SPECT-based 177Lu activity-concentration estimation using a ring-configured solid-state versus a dual-headed anger system

Background: The aim was to compare bias and precision for 177Lu-SPECT activity-concentration estimation using a dual-headed Anger SPECT system and a ring-configured CZT SPECT system. This was investigated for imaging at 208 keV and 113 keV, respectively. Methods: Phantom experiments were performed on a GE Discovery 670 system with 5/8’’ NaI(Tl) crystal (dual-headed Anger system) and a GE StarGuide

Representation of Complex Mammary Parenchyma Texture in Tomosynthesis Using Simplex Noise Simulations

The mammary parenchyma is a complex arrangement of tissues that can greatly vary among individuals, potentially masking cancers in breast screening images. In this work, we propose a Simplex-based method to simulate anatomical patterns and textures seen in digital breast tomosynthesis. Our approach involves selecting appropriate Simplex noise parameters to represent distinct categories of breast p

A Belief Propagation Algorithm for Multipath-Based SLAM with Multiple Map Features : A mmWave MIMO Application

In this paper, we present a multipath-based simultaneous localization and mapping (SLAM) algorithm that con-tinuously adapts mulitiple map feature (MF) models describing specularly reflected multi path components (MPCs) from flat surfaces and point-scattered MPCs, respectively. We develop a Bayesian model for sequential detection and estimation of interacting MF model parameters, MF states and mob

Rehabilitation coordinator – managers’ experiences of a new function in health care

Background: Several actions have been taken to improve the sick listing process, patient safety and return to work. One of them is the implementation of the rehabilitation coordinator function, of which the benefits have not yet been fully explored. Neither has the role of the manager, who has significant impact on the implementation and support of a new function. This study aimed to explore how f

Sub-100 fs Formation of Dark Excitons in Monolayer WS2

Two-dimensional semiconducting transition metal dichalcogenides are promising materials for optoelectronic applications due to their strongly bound excitons. While bright excitons have been thoroughly scrutinized, dark excitons have been much less investigated, as they are not directly observable with far-field spectroscopy. However, with their nonzero momenta, dark excitons are significant for ap

Introduction : Vaccine Hesitancy and the COVID-19 Crisis in the Nordic Countries

Already in 2019, WHO singled out the increase of vaccine hesitancy as one of the ten most important and urgent threats to global health. Little did people know then of the heated vaccine discussions waiting around the corner, spurred by the COVID-19 pandemic that set some countries on something reminiscent of a war footing. The mass vaccinations against the coronavirus in the early 2020s were seen

Variable associations of annual biomass increment with age, latitude and germination year in four tree species in Sweden

Forests are pivotal for biodiversity, food webs, and human economies, and as carbon sinks their climate change mitigation potential is undisputed. However, whether trees continue to efficiently accumulate biomass at an increasing rate with age, how growth trajectories respond to climate change, and vary with latitude at species range margins is under debate. Here, we combine tree-ring data with bi

Longitudinal stability of molecular endotypes of knee osteoarthritis patients

Objective: To assess the longitudinal stability of biomarker-based molecular endotypes of knee osteoarthritis (KOA) participants from APPROACH and to evaluate the consistency of findings in an independent KOA population. Methods: Nineteen biomarkers were measured longitudinally in 295 KOA participants from the APPROACH cohort. K-means clustering was used to identify the structural damage, inflamma

Islamic “interest-free” bonds-how Islamic are they?

The Islamic financial sector has developed its instruments rapidly since the 1960s, and a Muslim customer can get almost all financial services supplied by the conventional Western type of financial sector through so-called participation banks, which are run, it is said, in compliance with Islamic values and norms. For instance, they collect funds by special methods to finance economic activities,

Internal corporate venturing : riding the relational rollercoaster through sensemaking and sensegiving reconfiguration

Purpose: Internal corporate venturing is a vehicle for firms to realize strategic and financial goals through entrepreneurial ventures. Prior research presents a strategic process in which individual managers make rational choices based on their formal roles and top-down corporate objectives. Recent work has challenged this by adopting a relational approach using a macro-level perspective highligh

Assessing Mobility of Blind and Low-Vision Individuals Through a Portable Virtual Reality System and a Comprehensive Questionnaire

Blind or low-vision (BLV) individuals often have reduced independent mobility, yet new aids fails in increasing it, are not adopted enough, or both. A major cause is a severe deficiency in how mobility aids are assessed in the field: there are no established methods or measures and those used often have poor relevancy, insight affordances, and reproducibility; probing how actual BLV participants r

Surface Plasmon Resonance Nanosensors for the Sensing of Bacterial Threats

Microorganisms have unique biochemical mechanisms to inhibit the growth or kill other microorganisms in the same environment. Bacterial threat agents (BTA) are more effective than conventional weapons because of these characteristics, therefore, the development and production of biological weapons are still relevant. Early warning signals need to be obtained for fast and accurate detection of BTA

Engineering 2D Materials from Single-Layer NbS2

Starting from a single layer of NbS2 grown on graphene by molecular beam epitaxy, the single unit cell thick 2D materials Nb5/3S3-2D and Nb2S3-2D are created using two different pathways. Either annealing under sulfur-deficient conditions at progressively higher temperatures or deposition of increasing amounts of Nb at elevated temperature result in phase-pure Nb5/3S3-2D followed by Nb2S3-2D. The

24-hour Urine Calcium Predicts Reduced Fracture Incidence and Improved Bone Mineral Density After Surgery for Primary Hyperparathyroidism

Context: Contemporary patients with primary hyperparathyroidism are diagnosed with milder disease than previously. Clinical and biochemical factors predictors with an impact on fracture incidence and bone mineral density after surgery have not been firmly established. Objective: To investigate predictors of fracture incidence and bone mineral density preoperatively and after surgery for primary hy
