A Mildly Relativistic Outflow from the Energetic, Fast-rising Blue Optical Transient CSS161010 in a Dwarf Galaxy
- 2020
-
In: Astrophysical Journal Letters. - : American Astronomical Society. - 2041-8205 .- 2041-8213. ; 895:1
-
Journal article (peer-reviewed)abstract
- We present X-ray and radio observations of the Fast Blue Optical Transient CRTS-CSS161010 J045834-081803 (CSS161010 hereafter) at t = 69-531 days. CSS161010 shows luminous X-ray (L-x similar to 5 x 10(39) erg s(-1)) and radio (L-nu similar to 10(29) erg s(-1) Hz(-1)) emission. The radio emission peaked at similar to 100 days post-transient explosion and rapidly decayed. We interpret these observations in the context of synchrotron emission from an expanding blast wave. CSS161010 launched a mildly relativistic outflow with velocity Gamma beta c >= 0.55c at similar to 100 days. This is faster than the non-relativistic AT 2018cow (Gamma beta c similar to 0.1c) and closer to ZTF18abvkwla (Gamma beta c >= 0.3c at 63 days). The inferred initial kinetic energy of CSS161010 (E-k greater than or similar to 10(51) erg) is comparable to that of long gamma-ray bursts, but the ejecta mass that is coupled to the mildly relativistic outflow is significantly larger (similar to 0.01-.1 M-circle dot). This is consistent with the lack of observed gamma-rays. The luminous X-rays were produced by a different emission component to the synchrotron radio emission. CSS161010 is located at similar to 150 Mpc in a dwarf galaxy with stellar mass M-* similar to 10(7) M-circle dot and specific star formation rate sSFR similar to 0.3 Gyr(-1). This mass is among the lowest inferred for host galaxies of explosive transients from massive stars. Our observations of CSS161010 are consistent with an engine-driven aspherical explosion from a rare evolutionary path of a H-rich stellar progenitor, but we cannot rule out a stellar tidal disruption event on a centrally located intermediate-mass black hole. Regardless of the physical mechanism, CSS161010 establishes the existence of a new class of rare (rate < 0.4% of the local core-collapse supernova rate) H-rich transients that can launch mildly relativistic outflows.

- 2022
-
In: Foot & Ankle International. - : SAGE Publications. - 1071-1007 .- 1944-7876. ; 43:3, s. 448-452
-
Journal article (peer-reviewed)abstract
- Background: An international consensus group of experts was convened to collaboratively advance toward consensus opinions based on the best available evidence on key topics within cartilage repair of the ankle. The purpose of this article is to present the consensus statements on osteochondral lesions of the tibial plafond (OLTP) and on ankle instability with ankle cartilage lesions developed at the 2019 International Consensus Meeting on Cartilage Repair of the Ankle. Methods: Forty-three experts in cartilage repair of the ankle were convened and participated in a process based on the Delphi method of achieving consensus. Questions and statements were drafted within 4 working groups focusing on specific topics within cartilage repair of the ankle, after which a comprehensive literature review was performed and the available evidence for each statement was graded. Discussion and debate occurred in cases where statements were not agreed on in unanimous fashion within the working groups. A final vote was then held. Results: A total of 11 statements on OLTP reached consensus. Four achieved unanimous support and 7 reached strong consensus (greater than 75% agreement). A total of 8 statements on ankle instability with ankle cartilage lesions reached consensus during the 2019 International Consensus Meeting on Cartilage Repair of the Ankle. One achieved unanimous support, and seven reached strong consensus (greater than 75% agreement). Conclusions: These consensus statements may assist clinicians in the management of these difficult clinical pathologies.

Discovery and confirmation of the shortest gamma-ray burst from a collapsar
- 2021
-
In: Nature Astronomy. - : Springer Nature. - 2397-3366. ; 5:9, s. 917-927
-
Journal article (peer-reviewed)abstract
- Gamma-ray bursts (GRBs) are among the brightest and most energetic events in the Universe. The duration and hardness distribution of GRBs has two clusters1, now understood to reflect (at least) two different progenitors2. Short-hard GRBs (SGRBs; T90 < 2 s) arise from compact binary mergers, and long-soft GRBs (LGRBs; T90 > 2 s) have been attributed to the collapse of peculiar massive stars (collapsars)3. The discovery of SN 1998bw/GRB 980425 (ref. 4) marked the first association of an LGRB with a collapsar, and AT 2017gfo (ref. 5)/GRB 170817A/GW170817 (ref. 6) marked the first association of an SGRB with a binary neutron star merger, which also produced a gravitational wave. Here, we present the discovery of ZTF20abwysqy (AT2020scz), a fast-fading optical transient in the Fermi satellite and the Interplanetary Network localization regions of GRB 200826A; X-ray and radio emission further confirm that this is the afterglow. Follow-up imaging (at rest-frame 16.5 days) reveals excess emission above the afterglow that cannot be explained as an underlying kilonova, but which is consistent with being the supernova. Although the GRB duration is short (rest-frame T90 of 0.65 s), our panchromatic follow-up data confirm a collapsar origin. GRB 200826A is the shortest LGRB found with an associated collapsar; it appears to sit on the brink between a successful and a failed collapsar. Our discovery is consistent with the hypothesis that most collapsars fail to produce ultra-relativistic jets.

High-k/InGaAs interface defects at cryogenic temperature
- 2023
-
In: Solid-State Electronics. - 0038-1101. ; 207
-
Journal article (peer-reviewed)abstract
- Oxide defects in the high-k/InGaAs MOS system are investigated. The behaviour of these traps is explored from room temperature down to 10 K. This study reveals that the exchange of free carriers between oxide states and either the conduction or the valence band is strongly temperature dependant. The capture and emission of electrons is strongly suppressed at 10 K as demonstrated by the collapse of the capacitance frequency dispersion in accumulation for n-InGaAs MOS devices, though hysteresis in the C-V sweeps is still present at 10 K. Phonon assisted tunnelling processes are considered in the simulation of electrical characteristics. The simulated data match very well the experimental characteristics and provide energy and spatial mapping of oxide defects. The multi phonon theory also help explain the impedance data temperature dependence. This study also reveals an asymmetry in the free carrier trapping between n and p type devices, where hole trapping is more significant at 10 K.

Clinical Outcomes Of Osteoarthritis Management Programs: A Project Of The Oa Trial Bank And Oarsi Joint Effort Initiative Using Individual Participant Data
- 2023

In: Osteoarthritis and Cartilage. - : Elsevier. - 1063-4584 .- 1522-9653. ; 31, s. S385-S386

Journal article (peer-reviewed)abstract
- Purpose: People living with osteoarthritis (OA) often do not receive best evidence care. Coordinated OA management programs (OAMPs) have been implemented to address this global evidence-practice gap. An OAMP is defined as a package of care with the following: i) a personalized management plan; ii) with reassessment and progression; iii) using a minimum of 2 core treatments (education, exercise, weight control), and; iv) optional adjunctive therapies. Existing OAMP models differ in treatment mode, intensity, duration, the health professionals delivering care, and the healthcare systems and settings they operate within. Randomized trials (RCTs) and cohort studies assess the outcomes of different OAMPs, however, these models are unlikely to ever be compared in RCTs due to the huge expense and complicated logistics required. Prognosis research provides another method of comparing outcomes of different OAMP models. This study aimed to estimate the pain and self-reported function outcomes (at 12-, 26- and 52-weeks) of people with hip and/or knee OA who participated in international OAMPs. It also aimed to describe the characteristics of OAMP participants.Methods: This study was undertaken by members of the OARSI Joint Effort Initiative (JEI), in collaboration with the OA Trial Bank (Erasmus MC, Netherlands). RCTs and clinical cohorts assessing OAMPs were identified through the JEI membership and literature searches. Eligible studies included data from an ongoing OAMP, in any real-world setting, with participants who were diagnosed with hip or knee OA, and longitudinal measures of patient-reported pain and function. The investigators of eligible studies were invited to complete data delivery agreements with the OA Trial Bank, share individual participant data (IPD), contribute to study design and authorship. Investigators ensured they had local ethics review board approval to contribute IPD to the OA Trial bank. Each dataset was converted to a common format to enable merging into one dataset. The IPD were evaluated to convert pain and function variables to standardized scales as appropriate. Pain scores were converted to a 0-100 point scale (100 worst). Function scores were converted to a 0-100 point scale (100 best). A generalized estimating equations (GEE) model analysis was performed to assess the change in pain and function from baseline across weeks 12, 26, and 52. The model specification was based on an unstructured correlation structure and robust standard errors. Pain and function estimates were adjusted by age, sex and body mass index (BMI). Data analyses were carried out using Stata 15 (StataCorp 2015) and SPSS 17.Results: The investigators of 13 international OAMPs were invited to take part. IPD from 9 OAMPs were delivered: the OA Chronic Care Program, Ramsay Health OA Management Program, Joint Health Program, University of Wisconsin Health Knee and Hip Comprehensive Non-Surgical OA Management Clinic, Improved Management of Patients With Hip and Knee OA in Primary Health Care, Joint Academy, Amsterdam OA cohort, Management of OA In Consultations, and Collaborative model of care between Orthopaedics and allied healthcare professionals in knee OA. The characteristics of the OAMPs are summarised in table 1. The OAMPs were conducted in-person except for the Joint Academy that was implemented as an online OAMP. Individual participant data from 9819 participants were analyzed. The cohort studies were missing large amounts of data, as expected in clinical practice. The characteristics of OAMP participants are summarised in Table 2. The majority of OAMP participants reported the knee as their index joint, their mean age ranged between 62- 67 years, 58-74% were female, 25-48% were working and mean BMI indicated they were overweight at baseline. Pain was most commonly assessed using a Numeric Rating Scale or validated questionnaires e.g. the Knee Injury and OA Outcome Scale (KOOS). Function was mostly assessed using validated questionnaires such as the KOOS. The pain and fuction measured in the original datasets are reported in Table 1. The changes in pain and function of the OAMP participants from baseline across weeks 12, 26, and 52 are summarised in Table 3. There were reductions in pain scores and improvements in function scores seen across all programs at the majority of timepoints.Conclusions: We established the first data bank of IPD from different international OAMPs. Analysis of the IPD demonstrated modest improvements in pain and function across the programs at all timepoints. The most rapid improvements were made by week-12, however, these gains were maintained at week-52. In future work this project will use IPD meta-analysis to identify prognostic factors of people with OA who participate in OAMPs.

Common, intermediate and well-documented HLA alleles in world populations : CIWD version 3.0.0
- 2020
-
In: HLA. - : WILEY. - 2059-2302 .- 2059-2310. ; 95:6, s. 516-531

Journal article (peer-reviewed)abstract
- A catalog of common, intermediate and well-documented (CIWD) HLA-A, -B, -C, -DRB1, -DRB3, -DRB4, -DRB5, -DQB1 and -DPB1 alleles has been compiled from over 8 million individuals using data from 20 unrelated hematopoietic stem cell volunteer donor registries. Individuals are divided into seven geographic/ancestral/ethnic groups and data are summarized for each group and for the total population. P (two-field) and G group assignments are divided into one of four frequency categories: common (>= 1 in 10 000), intermediate (>= 1 in 100 000), well-documented (>= 5 occurrences) or not-CIWD. Overall 26% of alleles in IPD-IMGT/HLA version 3.31.0 at P group resolution fall into the three CIWD categories. The two-field catalog includes 18% (n = 545) common, 17% (n = 513) intermediate, and 65% (n = 1997) well-documented alleles. Full-field allele frequency data are provided but are limited in value by the variations in resolution used by the registries. A recommended CIWD list is based on the most frequent category in the total or any of the seven geographic/ancestral/ethnic groups. Data are also provided so users can compile a catalog specific to the population groups that they serve. Comparisons are made to three previous CWD reports representing more limited population groups. This catalog, CIWD version 3.0.0, is a step closer to the collection of global HLA frequencies and to a clearer view of HLA diversity in the human population as a whole.

Defective ZrSe2 : a promising candidate for spintronics applications
- 2024
-
In: Journal of Physics. - : IOP Publishing. - 0953-8984 .- 1361-648X. ; 36:13

Journal article (peer-reviewed)abstract
- The current study presents the electronic and magnetic properties of monolayer ZrSe2 nanoribbons. The impact of various point defects in the form of Zr or Se vacancies, and their combinations, on the nanoribbon electronic and magnetic properties are investigated using density functional theory calculations in hydrogen-terminated zigzag and armchair ZrSe2 nanoribbons. Although pristine ZrSe2 is non-magnetic, all the defective ZrSe2 structures exhibit ferromagnetic behavior. Our calculated results also show that the Zr and Se vacancy defects alter the total spin magnetic moment with D6Se, leading to a significant amount of 6.34 µB in the zigzag nanoribbon, while the largest magnetic moment of 5.52 µB is induced by D2Se−2 in the armchair structure, with the spin density predominantly distributed around the Zr atoms near the defect sites. Further, the impact of defects on the performance of the ZrSe2 nanoribbon-based devices is investigated. Our carrier transport calculations reveal spin-polarized current-voltage characteristics for both the zigzag and armchair devices, revealing negative differential resistance (NDR) feature. Moreover, the current level in the zigzag-based nanoribbon devices is ∼10 times higher than the armchair devices, while the peak-to-valley ratio is more pronounced in the armchair-based nanoribbon devices. It is also noted that defects increase the current level in the zigzag devices while they lead to multiple NDR peaks with rather negligible change in the current level in the armchair devices. Our results on the defective ZrSe2 structures, as opposed to the pristine ones that are previously studied, provide insight into ZrSe2 material and device properties as a promising nanomaterial for spintronics applications and can be considered as practical guidance to experimental work.

Bone mineral organization at the mesoscale: A review of mineral ellipsoids in bone and at bone interfaces
- 2022
-
In: Acta Biomaterialia. - : Elsevier BV. - 1742-7061. ; 142, s. 1-13
-
Journal article (peer-reviewed)abstract
- Much debate still revolves around bone architecture, especially at the nano- and microscale. Bone is a remarkable material where high strength and toughness coexist thanks to an optimized composition of mineral and protein and their hierarchical organization across several distinct length scales. At the nanoscale, mineralized collagen fibrils act as building block units. Despite their key role in biological and mechanical functions, the mechanisms of collagen mineralization and the precise arrangement of the organic and inorganic constituents in the fibrils remains not fully elucidated. Advances in three-dimensional (3D) characterization of mineralized bone tissue by focused ion beam-scanning electron microscopy (FIB-SEM) revealed mineral-rich regions geometrically approximated as prolate ellipsoids, much larger than single collagen fibrils. These structures have yet to become prominently recognized, studied, or adopted into biomechanical models of bone. However, they closely resemble the circular to elliptical features previously identified by scanning transmission electron microscopy (STEM) in two-dimensions (2D). Herein, we review the presence of mineral ellipsoids in bone as observed with electron-based imaging techniques in both 2D and 3D with particular focus on different species, anatomical locations, and in proximity to natural and synthetic biomaterial interfaces. This review reveals that mineral ellipsoids are a ubiquitous structure in all the bones and bone-implant interfaces analyzed. This largely overlooked hierarchical level is expected to bring different perspectives to our understanding of bone mineralization and mechanical properties, in turn shedding light on structure-function relationships in bone. Statement of significance: In bone, the hierarchical organization of organic (mainly collagen type I) and inorganic (calcium-phosphate mineral) components across several length scales contributes to a unique combination of strength and toughness. However, aspects related to the collagen-mineral organization and to mineralization mechanisms remain unclear. Here, we review the presence of mineral prolate ellipsoids across a variety of species, anatomical locations, and interfaces, both natural and with synthetic biomaterials. These mineral ellipsoids represent a largely unstudied feature in the organization of bone at the mesoscale, i.e., at a level connecting nano- and microscale. Thorough understanding of their origin, development, and structure can provide valuable insights into bone architecture and mineralization, assisting the treatment of bone diseases and the design of bio-inspired materials. © 2022 Acta Materialia Inc.

- Human activity and associated landscape modifications alter the movements of animals with consequences for populations and ecosystems worldwide. Species performing long-distance movements are thought to be particularly sensitive to human impact. Despite the increasing anthropogenic pressure, it remains challenging to understand and predict animals' responses to human activity. Here we address this knowledge gap using 1206 Global Positioning System movement trajectories of 815 individuals from 14 red deer (Cervus elaphus) and 14 elk (Cervus canadensis) populations spanning wide environmental gradients, namely the latitudinal range from the Alps to Scandinavia in Europe, and the Greater Yellowstone Ecosystem in North America. We measured individual-level movements relative to the environmental context, or movement expression, using the standardized metric Intensity of Use, reflecting both the directionality and extent of movements. We expected movement expression to be affected by resource (Normalized Difference Vegetation Index, NDVI) predictability and topography, but those factors to be superseded by human impact. Red deer and elk movement expression varied along a continuum, from highly segmented trajectories over relatively small areas (high intensity of use), to directed transitions through restricted corridors (low intensity of use). Human activity (Human Footprint Index, HFI) was the strongest driver of movement expression, with a steep increase in Intensity of Use as HFI increased, but only until a threshold was reached. After exceeding this level of impact, the Intensity of Use remained unchanged. These results indicate the overall sensitivity of Cervus movement expression to human activity and suggest a limitation of plastic responses under high human pressure, despite the species also occurring in human-dominated landscapes. Our work represents the first comparison of metric-based movement expression across widely distributed populations of a deer genus, contributing to the understanding and prediction of animals' responses to human activity.
