Effect of Cr variation on FCC phase fraction in AlCoCrxFeNi(x= 0 - 1) high-entropy alloys synthesised through mechanical alloying and spark plasma sintering [abstract]

The effect of Cr variation on FCC/BCC phase formation AlCoCrxFeNi (x=0 - 1) is explored in the present work. Cr is known to be a BCC stabilizerand s-phase former. These phases were reported in AlCoCrFeNi HEAobtained through casting route. We adopted mechanical alloying andspark plasma sintering route, since it suppresses certain complexphases. It is observed that the Cr assists in FCC phase in com

Effect of Cr content on FCC phase fraction of nanocrystalline AlCoCrxFeNi high entropy alloys synthesized by mechanical alloying and spark plasma sintering

Cr is known to be a BCC stabilizer in steels. In case of nanocrystalline AlCoCrFeNi high entropy alloys (HEA) synthesized by mechanical alloying (MA) and consolidated by spark plasma sintering (SPS), the systematic increase of Cr content from 0 mole to 1 mole supports and provides for the increase of Fe-Co-Cr rich FCC multicomponent phase. This increase in FCC phase fraction with increasing Cr con

The association of solitary versus group-based arts participation with mental health: evidence from the UK Household Longitudinal Study

Aims:Research on the role of art in alleviating mental health problems has increased dramatically. However, it remains unclear whether mental health benefits of the arts are the same across different social contexts of arts participation. The aim of the study is to investigate associations between two modes of arts participation, solitary and group-based, and psychological wellbeing (12-item gener

Natural Language Response Formats for Assessing Depression and Worry With Large Language Models: A Sequential Evaluation With Model Pre-Registration

Large language models can transform individuals’ mental health descriptions into scores that correlate with rating scales approaching theoretical upper limits. However, such analyses have combined word- and text responses with little known about their differences. We develop response formats ranging from closed-ended to open-ended: (a) select words from lists, write (b) descriptive words, (c) phra

Digital ASIC Automated Power Analysis

Ett automatiserat programflöde för att analysera effektförbrukningen i integrerade kretsar visar på bristerna i det manuella flödet. Genom att köra många slumpade testfall i effektuppskattningarna kan man upptäcka scenarier som ger högre effektförbrukning. Inom modern utveckling av integrerade kretsar, och inte minst inom de som utvecklas för telekommunikation, ställs det höga krav på energieffektThis thesis investigated the possibilities to automate the manual RTL power estimation flow for digital ASICs in Ericsson. The goal being to detect whether predefined power test cases that run with a single randomization seed are sufficient or if a multitude of seeds in an automated power flow could be used to detect scenarios with even higher activity. In order to automate the power estimation fl

Forest tree species classification and entropy-derived uncertainty mapping using extreme gradient boosting and Sentinel-1/2 data

We present a wall-to-wall map of dominant tree species in Swedish forests accompanied by pixel-level uncertainty estimates. The tree species classification is based on spatiotemporal metrics derived from Sentinel-1 and Sentinel-2 satellite data, combined with field observations from the Swedish National Forest Inventory and auxiliary data on geomorphometry and canopy height. We apply an extreme gr

Outcomes from the International Society of Nephrology Hemolytic Uremic Syndromes International Forum

Hemolytic uremic syndromes (HUSs) are a heterogeneous group of conditions, only some of which are mediated by complement (complement-mediated HUS). We report the outcome of the 2023 International Society of Nephrology HUS International Forum where a global panel of experts considered the current state of the art, identified areas of uncertainty, and proposed optimal solutions. Areas of uncertainty

Architecture of TOI-561 planetary system

We present new observations from CHEOPS (CHaracterising ExOPlanet Satellite) and TESS (Transiting Exoplanet Survey Satellite) to clarify the architecture of the planetary system hosted by the old Galactic thick disc star TOI-561. Our global analysis, which also includes previously published photometric and radial velocity data, incontrovertibly proves that TOI-561 is hosting at least four transiti

Myocardial Scarring and Sudden Cardiac Death in Young Patients with Hypertrophic Cardiomyopathy: A Multicenter Cohort Study

Importance: The ability to predict sudden cardiac death (SCD) in children and adolescents with hypertrophic cardiomyopathy (HCM) is currently inadequate. Late gadolinium enhancement (LGE) by cardiovascular magnetic resonance (CMR) imaging is associated with SCD events in adults with HCM. Objective: To examine the prognostic significance of LGE in patients with HCM who are younger than 21 years. De

Narrowing uncertainties in the effects of elevated CO2 on crops

Plant responses to rising atmospheric carbon dioxide (CO2) concentrations, together with projected variations in temperature and precipitation will determine future agricultural production. Estimates of the impacts of climate change on agriculture provide essential information to design effective adaptation strategies, and develop sustainable food systems. Here, we review the current experimental

Phase evolution in AlxCoCrFeNi (x= 0, 0.3, 0.6, 1 mole) high entropy alloys synthesized by mechanical alloying and spark plasma sintering

AlxCoCrFeNi (x=0,0.3,0.6,1 mole) high entropy alloys with multiprincipal elements and varying Al content were synthesized through mechanical alloying. Elemental blends of CoCrFeNi, Al0.3CoCrFeNi, Al0.6CoCrFeNi and AlCoCrFeNi powders were subjected to high energy ball milling in Fritsch Pulverisette P-5 until the formation of solid solution. The as-milled HEA powders having grain sizes of around 10

Effect of aluminium content and grain size on oxidation behavior of AlxCoCrFeNi (x=0, 0.3, 0.6, 1 mole) high entropy alloy

One of the most anticipated properties of high entropy alloys (HEA) is excellent oxidation resistance. AlxCoCrFeNi (x=0,0.3,0.6,1 mole) HEAs were synthesized by mechanical alloying (MA) followed by consolidation through spark plasma sintering (SPS). Alloys with x = 0 and 0.3 show single phase FCC structure, whereas those with x = 0.6 and 1 have dual phases – FCC and BCC. Interestingly, synthesis t

Towards sustainable DevOps for cyber physical systems

DevOps has significantly improved the software development life-cycle by enabling fast, automated, and continuous integration and deployment (CI/CD). However, its application to Cyber-Physical Systems (CPS) presents unique challenges that require rethinking of traditional practices. DevOps in CPS becomes even more challenging when we consider sustainability, which is becoming increasingly importan
