description: Digital coins have burst into mainstream awareness recently, mainly as a result of high-worth ‘Initial Coin Offerings’ (‘ICOs’). The most immediate question in the legal treatment of digital coins is whether they are properly seen as digital ‘commodities’, and/or as ‘securities’, and/or as units of ‘money’. But the conceptual underpinnings of these categories are not clear, nor is it clear how these categories relate to each other; no legal system currently deals adequately with incorporeal objects as objects of property law. This category includes not only digital coins but also some forms of conventional money and securities. Establishing a satisfactory account of their treatment in property law is therefore a necessary first step to incorporating digital coins into private law theory. I argue that this task is best approached on the basis of a plausible ontology of incorporeal objects, including those embodied in paper (i.e. banknotes and conventional securities) and those that exist natively in ‘cyberspace’ (i.e. electronic ‘book-money’, modern securities, and now digital coins). We therefore urgently need to develop a plausible account of a how packets of data can be treated as an object of property rights. Using a comparative analysis of English law and Civilian law (particularly German) concepts of property as an entry point into this complex of problems, I explore the ontology of incorporeal objects and the role of documentation in their creation and maintenance as part of the ‘ontic furniture’ of our economic world. I explore the conceptual basis of property in digital coins in terms of a new category of property. Such a category is long overdue and will be increasingly important in the future.

description: There is an increasing interest in the electronic properties of few layer graphene as it offers a platform to study electronic interactions because the dispersion of bands can be tuned with number and stacking of layers in combination with electric field. However, electronic interaction becomes important only in very clean devices and so far the trilayer graphene experiments are understood within non-interacting electron picture. Here, we report evidence of strong electronic interactions and quantum Hall ferromagnetism (QHF) seen in ABA trilayer graphene (ABA-TLG). Due to high mobility $\sim$500,000 cm$^2$V$^{-1}$s$^{-1}$ in our device compared to previous studies, we find all symmetry broken states and that Landau Level (LL) gaps are enhanced by interactions; an aspect explained by our self-consistent Hartree-Fock (H-F) calculations. Moreover, we observe hysteresis as a function of filling factor ($ν$) and spikes in the longitudinal resistance which, together, signal the formation of QHF states at low magnetic field.

description: A non-iterative method for the construction of the Short-Time Fourier Transform (STFT) phase from the magnitude is presented. The method is based on the direct relationship between the partial derivatives of the phase and the logarithm of the magnitude of the un-sampled STFT with respect to the Gaussian window. Although the theory holds in the continuous setting only, the experiments show that the algorithm performs well even in the discretized setting (Discrete Gabor transform) with low redundancy using the sampled Gaussian window, the truncated Gaussian window and even other compactly supported windows like the Hann window. Due to the non-iterative nature, the algorithm is very fast and it is suitable for long audio signals. Moreover, solutions of iterative phase reconstruction algorithms can be improved considerably by initializing them with the phase estimate provided by the present algorithm. We present an extensive comparison with the state-of-the-art algorithms in a reproducible manner.

description: By pumping thulium-doped silica-based fibers at 1.07~μm, rapid generation of absorbing centers leads to photo-induced attenuation (PIA). This detrimental effect prevents exploiting laser emissions in the visible and near infrared. We report on the characterization of the PIA versus the fiber core composition, particularly the concentration of thulium (Tm), lanthanum (La) and cerium (Ce) ions. We show that UV emision induced by Tm-Tm energy transfers is the source of photo-darkening, and that lanthanum and cerium are efficient hardeners against PIA.

description: {\bf Background:} Level sequences of rotational character have been observed in several nuclei in the $A=60$ mass region. The importance of the deformation-driving $πf_{7/2}$ and $νg_{9/2}$ orbitals on the onset of nuclear deformation is stressed.\\ {\bf Purpose:} A measurement was performed in order to identify collective rotational structures in the relatively neutron-rich $^{62}$Ni isotope. \\ {\bf Method:} The $^{26}$Mg($^{48}$Ca,2$α$4$nγ$)$^{62}$Ni complex reaction at beam energies between 275 and 320~MeV was utilized. Reaction products were identified in mass ($A$) and charge ($Z$) with the Fragment Mass Analyzer (FMA) and $γ$ rays were detected with the Gammasphere array. \\ {\bf Results:} Two collective bands, built upon states of single-particle character, were identified and sizable deformation was assigned to both sequences based on the measured transitional quadrupole moments, herewith quantifying the deformation at high spin. \\ {\bf Conclusions:} Based on Cranked Nilsson-Strutinsky calculations and comparisons with deformed bands in the $A=60$ mass region, the two rotational bands are understood as being associated with configurations involving multiple $f_{7/2}$ protons and $g_{9/2}$ neutrons, driving the nucleus to sizable prolate deformation.

description: The notions of weak measurement, weak value, and two-state-vector formalism provide a new quantum-theoretical frame for extracting additional information from a system in the limit of small disturbances to its state. Here, we provide an application to the case of two-body scattering with one body weakly interacting with an environment. The direct connection to real scattering experiments is pointed out by making contact with the field of impulsive incoherent neutron scattering from molecules and condensed systems. In particular, we predict a new quantum effect in neutron-atom collisions, namely an observable momentum transfer deficit; or equivalently, a reduction of effective mass below that of the free scattering atom. Two corroborative experimental findings are shortly presented. Implications for current and further experiments are mentioned. An interpretation of this effect and the associated experimental results within conventional theory is currently unavailable.

description: We investigate in this paper magnetic properties of the perovskite compound (La0.56Ce0.14)Sr0.30MnO3. The method we use here is Monte Carlo simulation, in which we take into account different kinds of interactions between nearest and between next-nearest magnetic ions Mn 3+ (S = 2) , Mn 4+ (S = 3/2) and Ce 3+ (S = 1/2). Using a classical spin model, we have calculated the internal energy, the magnetization per ion type and their corresponding magnetic susceptibility, as well as the Edwards-Anderson order parameter for each ion kind. We also studied the applied-field effect on the system magnetization. Our results show a good agreement with experiments.

Crystallography of deformation twinning in hexagonal close-packed metals. Revisiting the case of the (56 deg, a) contraction twins in magnesium
Creators: name: Cayron, Cyril
Publisher: name: arXiv
Year: 2016
Subjects: subject: Materials Science (cond-mat.mtrl-sci)
subject: FOS: Physical sciences

description: Contraction twinning in magnesium alloys leads to new grains that are misoriented from the parent grain by a rotation of 56 deg around the a-axis. The classical theory of deformation twinning does not precise the atomic displacements and does not explain why contractions twinning is less frequent than extension twinning. The paper proposes a new model in the continuity of our previous works on martensitic transformations and extension twinning. A continuous angular distortion matrix that transforms the initial hcp crystal into a final hcp crystal is determined such that the atoms move as hard spheres and reach the final positions expected by the orientation relationship. The calculations prove that the distortion is not a simple shear when it is considered in its continuity. The (01-11) twin plane is untilted and restored, but it is not fully invariant because some interatomic distances in this plane evolve during the distortion process; the unit volume also increases up to 5% before coming back to its initial value when the twinning distortion is complete. Then, the distortion takes the form a simple shear on the twin plane with a shear direction along the direction [18,-5,-5] and a shear amplitude of 0.358. It is the first time that this twinning mode is reported. Experiments are proposed to validate or infirm the new model.

description: This paper documents heat and fluid flow characteristics of the counterflow heat exchangers with line-to-line flow channels embedded fins of a fractal air-water cooler for hydrodynamic power plant generator which was analyzed numerically using AnSys 2021 R1 Fluent software to simultaneously solve the continuity, momentum, and heat equations in a 3D computational domain, and the conformal mesh technique is applied to generate the grid for the conjugate heat flow in the cooling system. At the low Reynolds numbers, the laminar viscous flow model was used, while at higher Re numbers Re~1200 the transitional flow regime was studied on the k-epsilon turbulent model. The governing pressure drop was ~(35-45)x105 Pa. Numerical results revealed that the fractal geometry can improve the integrated performance of the cooling system. The pressure drop through the pipe channel of the cooler as decreases obviously when compared with that of conventional parallel channels. The fractal system showed a more uniform temperature distribution and relatively lower maximum surface temperature. Application of the fins could intensify the transfer of heat remarkably and lower the power of the pump in a quick fashion related to the conventional tube system.

description: Despite the value that design methodologies have as a vehicle for learning science, technology, engineering, and mathematics (STEM)-related subject matter, their integration into STEM curricula remains a burgeoning phenomenon. The role of designing and the field's epistemological, ontological, axiological, and methodological foundations are still in the process of being shaped and refined by scholars in STEM-related fields. For instance, the knowledge base of designerly thinking and doing, though growing, is yet to be articulated in terms of “what” constitutes design knowledge, “how” it is constituted, “when” and “how” it is and can be acquired, and “why” it matters (Buckley et al., 2021). Furthermore, methodological frameworks for guiding, measuring, and evaluating designerly thinking, doing, and learning are in their developmental stages, indicating a need for empirical studies (Blom and Bogaers, 2020; Hartell and Buckley, 2021). The ontological perspectives of design—its nature, its purpose, and its role in learning and societal progress—are also subjects of ongoing discourse (Norström and Hallström, 2023). It is these challenges and opportunities that brought us to contribute to the maturation of these foundations, thereby cultivating a more robust understanding of design's role in STEM education.

description: We present a numerical path-integral iteration scheme for the low dimensional reduced density matrix of a time-dependent quantum dissipative system. Our approach simultaneously accounts for the combined action of a microscopically modelled pure-dephasing type coupling to a continuum of harmonic oscillators representing, e.g., phonons, and further environmental interactions inducing non-Hamiltonian dynamics in the inner system represented, e.g., by Lindblad type dissipation or relaxation. Our formulation of the path-integral method allows for a numerically exact treatment of the coupling to the oscillator modes and moreover is general enough to provide a natural way to include Markovian processes that are sufficiently described by rate equations. We apply this new formalism to a model of a single semiconductor quantum dot which includes the coupling to longitudinal acoustic phonons for two cases: a) external laser excitation taking into account a phenomenological radiative decay of the excited dot state and b) a coupling of the quantum dot to a single mode of an optical cavity taking into account cavity photon losses.

description: We calculate the spectrum of gravitational waves originated from strongly first order electroweak phase transition in the extended Higgs model with a real singlet field. In order to calculate the bubble nucleation rate, we perform a two-field analysis to evaluate bounce solutions connecting the true and the false vacua using the one-loop effective potential at finite temperatures. Imposing the Sakharov condition of the departure from thermal equilibrium for baryogenesis, we survey allowed regions of parameters of the model. We then investigate the gravitational waves produced at electroweak bubble collisions in the early Universe, such as the sound wave, the bubble wall collision and the plasma turbulence. We find that the strength at the peak frequency can be large enough to be detected at future space-based gravitational interferometers such as eLISA, DECIGO and BBO. Predicted deviations in the various Higgs boson couplings are also evaluated at the zero temperature, and are shown to be large enough too. Therefore, in this model strongly first order electroweak phase transition can be tested by the combination of the precision study of various Higgs boson couplings at LHC, the measurement of the triple Higgs boson coupling at future lepton colliders and the shape of the spectrum of gravitational wave detectable at future gravitational interferometers.

description: We report in situ LA-ICP-MS trace element analyses of silicate phases in olivine-bearing chondrules in the Sahara 97096 (EH3) enstatite chondrite. Most olivine and enstatite present rare earth element (REE) patterns comparable to their counterparts in type I chondrules in ordinary chondrites. They thus likely share a similar igneous origin, likely under similar redox conditions. The mesostasis however frequently shows negative Eu and/or Yb (and more rarely Sm) anomalies, evidently out of equilibrium with olivine and enstatite. We suggest that this reflects crystallization of oldhamite during a sulfidation event, already inferred by others, during which the mesostasis was molten, where the complementary positive Eu and Yb anomalies exhibited by oldhamite would have possibly arisen due to a divalent state of these elements. Much of this igneous oldhamite would have been expelled from the chondrules, presumably by inertial acceleration or surface tension effects, and would have contributed to the high abundance of opaque nodules found outside them in EH chondrites. In two chondrules, olivine and enstatite exhibit negatively sloped REE patterns, which may be an extreme manifestation of a general phenomenon (possibly linked to near-liquidus partitioning) underlying the overabundance of light REE observed in most chondrule silicates relative to equilibrium predictions. The silicate phases in one of these two chondrules show complementary Eu, Yb and Sm anomalies providing direct evidence for the postulated occurrence of the divalent state for these elements at some stage in the formation reservoir of enstatite chondrites. Our work supports the idea that the peculiarities of enstatite chondrites may not require a condensation sequence at high C/O ratios as has long been believed.

description: Recent advances in physical layer communication techniques, enable receivers to decode multiple simultaneous transmissions. This technique is known as the multipacket reception (MPR). In this paper, we propose an enhancement to the IEEE 802.11ac EDCA protocol for channels supporting MPR for QoS provisioning. We show that in the case of MPR, in addition to CWmin, CWmax and AIFSN, we can use two more parameters namely (i) threshold and (ii) counter decrement value, that can offer service differentiation. The performance evaluation of the different metrics of the proposed protocol (throughput, delay, and jitter) is carried out using extensive simulations.

description: A particularly simple setup is introduced to study the influence of time-delayed coherent feedback on the optical squeezing properties of the degenerate parametric amplifier (DPA). The possibility for significantly enhanced squeezing is demonstrated both on resonance and in sidebands, at a reduced pump power compared to the case without feedback. We study a broad range of operating parameters and their influence on the characteristic squeezing of the system. A classical analysis of the system dynamics reveals the connection between the feedback-modified landscape of stability and enhanced squeezing.

description: We study the low-frequency polarization response of a surface-charged oblate spheroidal particle immersed in an electrolyte solution. Because the charged spheroid attracts counter-ions which form the electric double layer around the particle, using usual boundary conditions at the interface between the particle and electrolyte can be quite complicated and challenging. Hence, we generalize Fixman's boundary conditions, originally derived for spherical particles, to the case of the charged oblate spheroid. Given two different counter-ion distributions in the thin electric double layer limit, we obtain analytic expressions for the polarization coefficients to the first non-trivial order in frequency. We find that the polarization response normal to the symmetry axis depends on the total amount of charge carried by the oblate spheroid while that parallel to the symmetry axis is suppressed when there is less charge on the edge of the spheroid. We further study the overall dielectric response for a dilute suspension of charged spheroids. We find that the dielectric enhancement at low frequency, which is driven by the presence of a large $ζ$-potential (surface charge), is suppressed by high ion concentrations in the electrolyte and depends on the size of the suspended particles. In addition, spheroids with higher aspect ratios will also lead to a stronger dielectric enhancement due to the combination of the electric double layer and textural effects. The characteristic frequency associated with the dielectric enhancement scales inversely with the square of the particle size, the major radius of the spheroid, and it has a weak dependence on the shape of spheroids.

description: Aim: To summarize current literature on the definition, categorization and measurement of social support in studies of work-related musculoskeletal disorders among hospital nurses. Design: A scoping review. Data Sources: A literature search of four databases (CINAHL, Medline, Embase and Web of Science) was employed to map the evidence between January 2012 and April 2023 on the definition, categorization and measurement of social support in studies of work-related musculoskeletal disorders among nurses in hospital settings. Review Methods: This review adopted Arksey and O'Malley's framework for conducting scoping reviews. Data extraction was reported using PRISMA Scoping Review guidelines and articles synthesized using a descriptive approach. Results: Fifteen studies met the criteria for inclusion in the review. Social support was distinctly defined in only two studies. Four main categories of social support identified were Co-worker, Supervisor, Family and Overall support. Eight tools were found to measure social support, and the most used tool was the Job Content Questionnaire. Conclusions: The review identified that social support is often not explicitly defined. Furthermore, social support can be categorized and measured in different ways, using diverse tools. This variation may affect the understanding of social support and the approaches in measuring and providing social support in the workplace. Impact: Studies should clearly define the social support category evaluated, to facilitate comparisons between studies of nurses with work-related musculoskeletal disorders. Healthcare managers should obtain feedback from nurses to ensure that the category of social support provided matches that which the nurse requires to ensure it helps the nurse from an organizational perspective. Healthy social relationships should be encouraged among nurses to promote nurses' well-being and by extension patient care. Patient or Public Contribution: There was no patient or public involvement.

description: Mechanical resonators are ubiquitous in modern information technology. With the ability to couple them to electromagnetic and plasmonic modes, they hold the promise to be the key building blocks in future quantum information technology. Graphene based resonators are of interest for technological applications due to their high resonant frequencies, multiple mechanical modes, and low mass. The tension mediated non-linear coupling between various modes of the resonator can be excited in a controllable manner. Here, we engineer a graphene resonator to have large frequency tunability at low temperatures resulting in large intermodal coupling strength. We observe the emergence of new eigenmodes and amplification of the coupled modes using red and blue parametric excitation respectively. We demonstrate that the dynamical intermodal coupling is tunable. A cooperativity of 60 between two resonant modes of ~100 MHz is achieved in the strong coupling regime. The ability to dynamically control the coupling between high frequency eigenmodes of a mechanical system opens up possibility for quantum mechanical experiments at low temperatures.

description: As many technologies are focusing on the miniaturization of its products, the ability to pattern at the micro/nano scale over the large areas on material surfaces is critical to the development of next generation technologies. In this work, novel composite nonporous gold (np-Au) stamp for capillary microprinting of polymer melts has been developed. Developed stamp enables printing of polymers from their melts which offers advantages to solution printing because the evaporation of volatile organic solvents is circumvented. The stamp consists of two parts, the porous gold layer with arrays of contact elements on the surface and the polymer layer that serves both as ink reservoir and as stabilizing support for the thin gold film. The continuous network of pores throughout the gold layer connected with the polymer film that serves as ink reservoir enables the stamping in consecutive cycles. First, polystyrene melts were printed on the glass substrates as a proof of concept for the use of composite np-Au in capillary printing. Printing of polystyrene melts has also been used for optimization of the stamping process. Then, printing of ferroelectric polymer poly(vinylidenefluoride)-trifluoroethylene (P(VDF-TrFE)) on glass and aluminium coated Si wafers (Al/Si) was conducted. Printing of both polymer inks was done with different stamping times, and the influence of the stamping time on the dimensions of the deposited structures (diameter and height) was investigated.

description: A polyomino is said to be L-convex if any two of its cells are connected by a 4-connected inner path that changes direction at most once. The 2-dimensional language representing such polyominoes has been recently proved to be recognizable by tiling systems by S. Brocchi, A. Frosini, R. Pinzani and S. Rinaldi. In an attempt to compare recognition power of tiling systems and cellular automata, we have proved that this language can be recognized by 2-dimensional cellular automata working on the von Neumann neighborhood in real time. Although the construction uses a characterization of L-convex polyominoes that is similar to the one used for tiling systems, the real time constraint which has no equivalent in terms of tilings requires the use of techniques that are specific to cellular automata.

description: The first V Rc Ic bands light curves of MQ UMa are presented and analyzed using the Wilson-Devinney (W-D) program. It is discovered that MQ UMa is an A-subtype contact binary with a high fill-out (f=82 %) and a low mass ratio (q = 0:195), which indicates that it is in the late evolutionary stage of latetype tidal-locked binary stars. The mass of the primary and secondary stars are estimated and the evolutionary status of the two components are placed in the H-R diagram. The W-D solutions also indicates that MQ UMa may be a triple system with an F5V type additional component. A sample of sixteen high fillout, low mass ratio overcontact binaries are collected and their possible evolution scenarios are discussed. Using the five times of light minimum recently observed together with those collected from literatures, the authors find that the observedcalculate (O-C) curve exhibits a cyclic period variation. The cyclic period change also reveals the presence of a tertiary component, which may play an important role in the formation and evolution of this binary system by drawing angular momentum from the central system.

description: Η εργασία με τίτλο “Οικονομική αποτίμηση της υπηρεσίας προστασίας από πλημμύρες στον Δήμο Βόλου με την μέθοδο της μεταφοράς οφέλους “(benefit transfer)” αποτελεί την διπλωματική εργασία του Ιωάννη Κοκκινίδη που εκπονήθηκε στο πλαίσιο του Προγράμματος Μεταπτυχιακών Σπουδών “Προστασία Περιβάλλοντος και Βιώσιμη Ανάπτυξη” του Τμήματος Πολιτικών Μηχανικών του Αριστοτέλειου Πανεπιστήμιου Θεσσαλονίκης. Στην εργασία αυτή, έγινε μία προσπάθεια να εκτιμηθεί η δυνητική προθυμία πληρωμής των κατοίκων του Δήμου Βόλου για αντιπλημμυρική προστασία με την μέθοδο της μεταφοράς οφέλους (benefit transfer). Λόγω του εύρους της έννοιας “οικονομική αποτίμηση” η εργασία επικεντρώθηκε στην αναζήτηση ελληνικής και διεθνούς βιβλιογραφίας η οποία θα αφορούσε την σχέση μεταξύ της προθυμίας των ανθρώπων για πληρωμή και τις δημόσιες επενδύσεις σε μέτρα προστασίας από τις πλημμύρες. Μέσω της μελέτης, παρουσιάστηκαν οι κυριότεροι παράγοντες που επηρεάζουν την προθυμία και την στάση των ανθρώπων γύρω από μία οικοσυστημική υπηρεσία καθώς και η μεθοδολογία αξιολόγησης μίας τέτοιας υπηρεσίας με την μέθοδο της μεταφοράς οφέλους (benefit transfer)
description: The present research with title: "Economic Valuation of Flood Protection Service in the Municipality of Volos using Benefit Transfer Method" is the master's thesis of Ioannis Kokkinidis, conducted during the Postgraduate Program in Environmental Protection and Sustainable Development at the Department of Civil Engineering of the Aristotle University of Thessaloniki. In this thesis, an attempt was made to estimate the potential willingness to pay by the residents of the Municipality of Volos for flood protection using the benefit transfer method. Due to the broad concept of "economic valuation," the study focused on the research for greek and international literature related to the relationship between people's willingness to pay and public investments in flood protection measures. Through the study, the main factors influencing people's willingness and attitudes toward an ecosystem service were presented, as well as the methodology for evaluating such a service using the benefit transfer method

description: We report on the systematic characterization of Ba(Fe$_{0.92}$Co$_{0.08}$)$_2$As$_2$ epitaxial thin films on CaF$_2$ substrate in view of their possible use for superconducting electronic applications. By using different and complementary techniques we studied the morphological characteristics of the surface, the structural properties, the magnetic response, and the superconducting properties in terms of critical temperature, critical current, and energy gaps. Particular attention was paid to the homogeneity of the films and to the comparison of their superconducting properties with those of single crystals of the same compound.

description: To assess the association between sex and clinical and disease activity indices, and X-rays and magnetic resonance imaging (MRI) features, in early-stage axial spondyloarthritis (axSpA). Baseline data analysis was conducted on the Italian SPACE cohort, including patients with chronic back pain (duration ≥ 3 months and ≤ 2 years; onset < 45 years). Patients underwent MRI and X-rays of the sacroiliac joints (SIJs) to establish the diagnosis of axSpA, according to Assessment of SpondyloArthritis international Society criteria and physician’s judgement. Clinical features, disease activity and functional indices, and images were collected at baseline and yearly during 48 months. Spinal and SIJ X-rays and MRI images were scored by two readers following Spondyloarthritis Research Consortium of Canada (SPARCC), modified Stoke Ankylosing Spondylitis Spinal Score, and modified New York criteria. Characteristics of axSpA patients according to sex (male/female) were compared over time using descriptive statistics. Ninety-one patients had axSpA (83.5% non-radiographic; 16.5% radiographic); 47.3% were male. Males were younger, with shorter duration of axial symptoms, and more frequently had HLA-B27 positivity, radiographic sacroiliitis with a bilateral/symmetric pattern, and more signs of spondylitis. Females more frequently showed peripheral/entheseal involvement and the non-radiographic phenotype. Males showed increased pelvic/spinal radiographic progression and more often had active sacroiliitis on MRI. Although the frequency of inflammatory corner lesions did not differ between males and females, localization varied, with more cervical/thoracic MRI-spine lesions in females and more lumbar lesions in males. We observed a significant downward trend of SPARCC SIJ/spine scores in all patients, irrespective of sex. More fat lesions were observed on MRI-spine in females and on MRI-SIJ in males. Sex was associated with distinct axSpA features: females showed low-grade radiographic sacroiliitis and spinal progression, and a higher prevalence of cervical and thoracic spine MRI signs.

description: Due to their high strength and advantageous high-temperature properties, tungsten-based alloys are being considered as plasma-facing candidate materials in fusion devices. Under neutron irradiation, rhenium, which is produced by nuclear transmutation, has been found to precipitate in elongated precipitates forming thermodynamic intermetallic phases at concentrations well below the solubility limit. Recent measurements have shown that Re precipitation can lead to substantial hardening, which may have a detrimental effect on the fracture toughness of W alloys. This puzzle of sub-solubility precipitation points to the role played by irradiation induced defects, specifically mixed solute-W interstitials. Here, using first-principles calculations based on density functional theory, we study the energetics of mixed interstitial defects in W-Re, W-V, and W-Ti alloys, as well as the heat of mixing for each substitutional solute. We find that mixed interstitials in all systems are strongly attracted to each other with binding energies of -2.4 to -3.2 eV and form interstitial pairs that are aligned along parallel first-neighbor <111> strings. Low barriers for defect translation and rotation enable defect agglomeration and alignment even at moderate temperatures. We propose that these elongated agglomerates of mixed-interstitials may act as precursors for the formation of needle-shaped intermetallic precipitates. This interstitial-based mechanism is not limited to radiation induced segregation and precipitation in W-Re alloys but is also applicable to other body-centered cubic alloys.

description: Hysterectomy is the most common gynaecological surgery, performed mainly for benign uterine pathologies in women. Studies have suggested that hysterectomy is associated with osteoarthritis (OA); however, the association remains controversial. This study aimed to investigate the association between hysterectomy and the risk of OA. We performed a population-based nested case–control study using the National Health Insurance programme database from 2000 to 2016 in Taiwan. All medical conditions for each case and control were categorized using the International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) and ICD-10. A multiple conditional logistic regression model was applied to analyse the adjusted odds ratio (aOR) and 95% confidence interval (CI) for the association between hysterectomy and OA. Our analyses included 16 592 patients with OA and 66 368 matched controls. After adjustment for possible confounders, hysterectomy had a significant association with OA (aOR = 1.19, 95% CI = 1.09–1.30), especially knee OA (aOR = 1.25, 95% CI = 1.13–1.38). Furthermore, women who received oestrogen therapy (ET) alone and patients who underwent hysterectomy without ET showed a greater risk of OA development compared to women who did not receive ET (aOR = 1.14, 95% CI = 1.07–1.23, and aOR = 1.19, 95% CI = 1.08–1.31, respectively). Our findings indicate that hysterectomy is associated with OA, especially knee OA. We also found that women who received ET alone and patients who underwent hysterectomy without ET had an increased risk of OA.

description: Glucocorticoids (GCs) remain a cornerstone of the initial management of anti-neutrophil cytoplasm antibody (ANCA)-associated vasculitis (AAV), but have several dose-dependent side effects, in particular infections. The optimal dosing and tapering of oral GCs for remission induction are unknown. A systematic review and meta-analysis was undertaken to determine the efficacy and safety of low- versus high-dose GC regimens. A systematic search of MEDLINE, Embase, and PubMed databases was conducted. Clinical studies using a GC-based induction protocol were selected. A daily dose of 0.5 mg/kg or < 30 mg/day oral prednisolone equivalent by the start of week 4 of the induction tapering schedule marked the threshold between high- and low-dose GCs. Risk ratios (RRs) were calculated by the random effects model for outcomes of remission and infection. Relapse events were summarized using risk differences with 95% confidence intervals (CIs). In total, 1145 participants were included in three randomized controlled trials and two observational studies, of whom 543 were assigned to the low-dose GC group and 602 to the high-dose GC group. A low-dose GC regimen was non-inferior to high-dose GCs with respect to outcomes of remission (RR 0.98, 95% CI 0.95–1.02, p = 0.37; I2 = 0%) and relapse (risk difference 0.03, 95% CI −0.01 to 0.06, p = 0.15; I2 = 12%), while significantly reducing the incidence of infection (RR 0.60, 95% CI 0.39–0.91, p = 0.02; I2 = 65%). Studies with low-dose GC regimens in AAV are associated with fewer infections while obtaining equivalent efficacy.
