Projected Intensification of Hydroclimatic Extremes in Rio Grande do Norte, Brazil, Under CMIP6 Scenarios

International Journal of Climatology, EarlyView.
The graphical abstract presents observed (1963–2023) and projected changes in hydroclimatic extremes in Rio Grande do Norte, Brazil. It integrates dry‐spell duration (CDD) and extreme precipitation (R95pTOT) using CMIP6 multimodel ensembles under SSP1‐2.6, SSP2‐4.5, and SSP5‐8.5.

What Do Latest CMIP6 Global Climate Models Say About Future Arctic Sea Ice Coverage Changes?

International Journal of Climatology, EarlyView.
Modelling of sea ice dynamics has significantly improved between CMIP5 and CMIP6, with nearly three times as many models capturing realistic annual variability in sea ice extent (SIE). What we previously thought was a non‐linear pattern of low SIE observations in 2007–2010 that would continue throughout time now appears to be non‐record‐setting lows in

The Role of Daily and Monthly Bias Corrected Data in Preserving the Monthly Cross‐Correlation Between Precipitation and Temperature

International Journal of Climatology, EarlyView.
Daily bias‐correction aggregated to monthly scale preserves the cross‐correlation between precipitation and temperature better than direct monthly bias‐correction. The Canonical Correlation Analysis (CCA) method outperforms Quantile Regression (QR) and MACA, yielding lower bias and higher accuracy, highlighting its suitability for multivariate climate ...

FastECPP over MPI

The FastECPP algorithm is currently the fastest approach to prove theprimality of general numbers, and has the additional benefit of creatingcertificates that can be checked independently and with a lower complexity.This article shows how by parallelising over a linear number of cores,its quartic time complexity becomes a cubic wallclock time ...

Three Generations of NARCliM: Evaluation of Precipitation, Temperature and Their Extremes Over the CORDEX Australasia Domain

International Journal of Climatology, EarlyView.
The NSW and Australian Regional Climate Modelling Version 2.0 (NARCliM2.0) builds on NARCliM1.0 and 1.5 to deliver improved regional climate simulations. This study provides the first comprehensive evaluation of NARCliM2.0 against its predecessors, assessing individual model skill in reproducing mean and extreme climate.

Solar Geoengineering Effects on Malaria Transmission Risk in South Asia Under G6sulfur Scenario

International Journal of Climatology, EarlyView.
Comparison of EIR (unit: No of infected bites per person per day) for each considered country in South Asia, under the considered scenarios, averaged over the period 2020–2090. A regression equation is shown for each country (for Bhutan EIRG = 0.1690 × 10−10 EIRS + 0.5968 × 10−12) to illustrate the projected trend.

How Well Do CMIP6 Models Simulate the Influence of the West African Westerly Jet on Sahel Precipitation?

International Journal of Climatology, EarlyView.
Climate models generally reproduce the WAWJ and August peak but simulate its onset prematurely and too strongly relative to ERA5. CMIP6 simulations struggle to reproduce the jet–precipitation relationship in the Sahel and underrepresent associated moisture transports.

Analysis of the periodic variation of pellet ablation radiation intensity in ASDEX Upgrade

Nuclear Fusion
In a future fusion reactor, the main fuelling method will likely rely on the injection of solid hydrogen pellets. Current predictions assume that this goal can be achieved, since being based on a technology which is already largely developed.

Peri‐implant hypoxia as a potential barrier against ferroptotic mechanisms during peri‐implant diseases: A cross‐sectional study

Journal of Periodontology, EarlyView.
Abstract Background Hypoxia modulates inflammation and oxidative stress through hypoxia‐inducible factor‐1α (HIF‐1α). Ferroptosis, an iron‐dependent cell death process, is regulated by glutathione peroxidase‐4 (GPX4) and involves lipid peroxidation markers like malondialdehyde (MDA).

Hemodynamic Significance of APEXCT Coronary Angiography Combined With Dynamic CT Myocardial Perfusion Imaging in Assessing Restenosis After Coronary Stenting

The Kaohsiung Journal of Medical Sciences, EarlyView.
ABSTRACT This study aimed to evaluate the hemodynamic significance of in‐stent restenosis (ISR) by using a combined anatomical‐functional approach with photon‐counting CT coronary angiography (APEX‐CT CTA) and dynamic CT myocardial perfusion imaging (CT‐MPI). We prospectively enrolled 239 symptomatic patients at least 9 months after PCI.
