Ultrahigh flow strength in shocked nanopolycrystalline diamond

Extreme pressures and temperatures create conditions that allow even hard and brittle materials to flow plastically. Despite extensive research, the limits of flow strength under such conditions remain uncertain, and the mechanisms driving deformation at the relevant stresses are...

Differentiable latent structure discovery for interpretable forecasting in clinical time series

Abstract Background Timely, uncertainty-aware forecasting from irregular electronic health records (EHR) can support critical-care decisions, yet most approaches either impute to a grid or sacrifice interpretability. We introduce StructGP, a continuous-time multi-task Gaussian pr...

The Cloud Feedback Model Intercomparison Project (CFMIP) contribution to CMIP7

Cloud processes constitute one of the key uncertainties for climate change projections. The fourth iteration of the Cloud Feedback Model Intercomparison Project, CFMIP4, contributes to the Coupled Model Intercomparison Project phase 7 (CMIP7), by providing a set of global climate...

On the Timescales of Atmospheric Adjustments to Contrail Cirrus Formation

Abstract Condensation trails (contrails) that evolve into contrail cirrus may constitute the largest contribution to aviation's climate impact. However the strength and timescales of the adjustments of the upper atmospheric water budget to contrail formation are poorly known. Tha...

Primary healthcare centers as key partners in HPV self-sampling: a mixed-methods study on feasibility and acceptance in rural areas near Quito, Ecuador

Cervical Cancer (CC), preventable through vaccination and screening, is the second most common cancer among Ecuadorian women. Access to screening is unequal, with rural populations disproportionally affected by limited healthcare resources, transportation, and poverty. While huma...

The NPIS model: a consensus-based framework for evaluating non-pharmacological interventions

The term non-pharmacological intervention (NPI) refers to health prevention and care protocols supervised by healthcare professionals. However, no precise and widely adopted definition currently exists. Additionally, unlike drugs, NPIs do not have a global evaluation framework be...

Hoeffding adaptive splitting trees for data stream classification with concept drift and ensemble learning

Abstract Ensembles of decision trees are well-established methods for data stream classification. In ensemble learning, Hoeffding Trees are widely adopted as base learners, performing periodic split attempts according to the Hoeffding bound. Recent studies, however, indicate that...

Local and Systemic Risk Factors of Dental Biofilm‐Induced Gingivitis and Their Control: A Systematic Review

ABSTRACT Objectives To identify local and systemic risk factors/indicators for dental biofilm‐induced gingivitis (DB‐GI) and to summarize evidence for their control. Methods A systematic review was undertaken following Preferred Reporting Items for Systematic Review and Meta‐Anal...

Migration and tuberculosis transmission in Hamburg, Germany: insights from 25 years of molecular epidemiology

Abstract Background Tuberculosis (TB) epidemiology in low-incidence settings is increasingly influenced by the importation of Mycobacterium tuberculosis complex (Mtbc) strains from high-incidence regions. Globally, more virulent “generalist” lineages such as Lineage 2 (L2) and Li...

Effects of radiative heat transfer on premixed spherically expanding NH3-air flames

This article numerically investigates the effects of radiation on the laminar burning velocity (LBV) extrapolated from microgravity spherical expanding NH 3 /air premixed flames, with equivalence ratios and pressures ranging from 0.7 to 1.3 and 1 to 50 atm, respectively. The simu...

Settlement and Landscape Transformations in the Khaybar Oasis From Late Antiquity to the Late Islamic Period

ABSTRACT Archaeological survey and targeted soundings by the Khaybar Longue Durée Archaeological Project ( Khaybar LDAP ) have provided the opportunity to reconstruct a first overview of settlement dynamics, land use and socioeconomic organisation from the late pre‐Islamic period...

Evaluation of ASCAT soil moisture retrievals and their potential to detect intraday variability

Accurate sub-daily soil moisture (SM) retrievals from satellite observations remain a major challenge due to sparse temporal sampling and retrieval uncertainties. This study introduces a localized convolutional neural network (CNN-l) framework designed to enhance SM estimates fro...

Almost sure upper bound for random multiplicative functions

Let ε>0. Let f be a Steinhaus or Rademacher random multiplicative function. We prove that almost surely, as x→+∞, ∑n⩽xf(n)≪x√(log2x)3/4+ε.

Photovoltaic panels affect arthropod and plant communities: a systematic review

Due to climate change, photovoltaic facilities are being rapidly scaled up. However, such a development can come at a cost for biodiversity. We conducted a systematic review, including a critical appraisal, and meta-analyses to better understand the effects of photovoltaic panels...

Effects of biodynamic preparations on grape skin structure and composition

Biodynamic viticulture, with its holistic philosophy, is gaining traction among professionals in the French wine industry. This approach incorporates the use of compost, herbal infusions, and organic and mineral preparations. Many biodynamic winegrowers highlight the impact of th...

Bridging the gap between genomic, phenotypic, and modeling data in picophytoplankton–virus interactions

Abstract We present a comprehensive synthesis of recent developments in methodological approaches to combine experimental and genomic studies of picophytoplankton–virus interactions. This synthesis will not only enhance our understanding of these relationships but also stimulate...

Symmetry-based pulsed DNP and EPR sequences

Pulsed microwave irradiation provides more versatile control over spin dynamics than continuous-wave (CW) methods. This study adapts symmetry-based dipolar recoupling sequences, which are originally designed for magic angle spinning (MAS) NMR, to exploit electron-nuclear interact...

Anesthesia TeleConsultation for Pediatric preoperative assessment: a large national prospective multicentric study in children (TeleCCCAP)

Background: While interest in pediatric anesthesia teleconsultation is growing, published data remain scarce. This study evaluated the feasibility of anesthesia teleconsultation in children, providing a comprehensive analysis of failure, quality, dedicated time and satisfaction....

Cytomegalovirus Latency Fuels Inflammation Following Myocardial Infarction

BACKGROUND: Epidemiological studies have consistently associated cytomegalovirus (CMV) seropositivity with adverse cardiovascular outcomes. However, the mechanisms by which cytomegalovirus infection impacts pathophysiology in the heart remain poorly understood. In this study, we...

Similar pre-eruptive conditions behind contrasting explosive and effusive trachytic eruptions at Montagnone (Ischia volcano, Italy)

Abstract Most volcanoes on Earth display a range of eruptive styles, varying between effusive and explosive activity. Understanding the factors controlling these transitions is critical for volcanic hazard assessment but remains debated. While both pre-eruptive storage conditions...
