Decreased precipitation frequency increases nitrogen loss across degraded grasslands in a two-year mesocosm experiment

Soil inorganic nitrogen (N) is frequently lost from grasslands through gaseous emissions and leaching, both strongly regulated by precipitation, reducing soil nutrient availability and influencing offsite environments. Amid declining precipitation frequency and widespread grassla...

Transfer learning applied to tidal current predictions with limited data availability

Accurate prediction of tidal current velocities is crucial for various applications, such as estimating energy production in tidal power projects. However, Acoustic Doppler current profiler (ADCP) campaigns are often expensive and can lead to incomplete data. This study addresses...

Multimodal Prodromal Patterns Associated with COPD Exacerbations in Home Telemonitoring: An Exploratory Observational Study

Characterizing multi-parameter physiological, acoustic, and environmental changes before acute chronic obstructive pulmonary disease exacerbations (AECOPD) is crucial for improving home telemonitoring and enabling timely clinical intervention. In a 12-month prospective observatio...

On a Class of Random Distortions Based on Hazard-Operator Families

Abstract Motivated by case studies focusing on a random replacement model and a catastrophe-based failure model, in this paper we propose a class of random distortions obtained by acting on the baseline cumulative hazard through a family of random hazard operators. We investigate...

Land use intensification results in abrupt transitions between extensively and intensively managed grasslands

Abstract Understanding whether land use intensification causes regime shifts (i.e. persistent, large changes in ecosystem states) is of key importance for management, particularly if these shifts occur abruptly as thresholds in land use intensity are crossed. Further, these thres...

Device-Measured Physical Activity, Sedentary Time, and Cardiometabolic Risk Markers in Youth

Importance The evidence for benefits of higher physical activity and lower sedentary time on the cardiometabolic risk profile in youth is based on cross-sectional and small prospective studies. Objective To determine the prospective associations between device-measured physical a...

Modal Identification of a Superimposed Structure: The Crossing of the Mosque–Cathedral of Córdoba

The Gothic–Renaissance crossing of the Mosque–Cathedral of Córdoba constitutes one of the most structurally complex sectors of the monument owing to the coexistence of Islamic and Christian construction systems developed over several centuries. Accurately reproducing the mechanic...

Satellite-based coastal monitoring through variance image composites (SatVar)

The past decade has seen rapid advancements in satellite remote sensing data availability and analysis. In coastal environments, this has enabled regional to global assessments of shoreline trends, a key practical application for management and planning. However, coastal zones ar...

Cluster‐Defined Response Patterns Following Pain Neuroscience Education With Physical Activity in Older Women With Chronic Low Back Pain: A Quasi‐Randomized Exploratory Study

ABSTRACT Background and Aims To explore patterns of treatment response to pain neuroscience education combined with physical activity (PNE‐PA) and to examine baseline characteristics associated with these patterns in older women with chronic low back pain (CLBP). Methods In a com...

Impact of Rapid Thermal Annealing on the Structural and Piezoelectric Properties of AlN Thin Films

ABSTRACT Aluminum nitride (AlN) is a biocompatible piezoelectric material with energy harvesting properties. This study examines the effects of post‐deposition rapid thermal annealing (RTA) on AlN thin films used in microelectromechanical systems (MEMS) resonators. RTA is perform...

Factors associated with depression and anxiety in people who have suffered an acute myocardial infarction and undergone revascularization via percutaneous coronary intervention: a cross-sectional study

Acute myocardial infarction (AMI) is a cardiovascular event that has a significant clinical, functional, and emotional impact. Patients may experience anxiety and depression that could influence their recovery. This study aimed to identify the association between various biopsych...

Association between ultra-processed food consumption and depressive symptoms in individuals with type 2 diabetes

Ultra-processed food (UPF) consumption has been associated with adverse metabolic and mental health outcomes, yet evidence among individuals with type 2 diabetes mellitus (T2DM) remains limited. This study aimed to examine the association between UPF consumption and depressive sy...

Measurement Agreement and Reliability of the 6‐m Gait Speed Test in Adult Population: The ADULT‐FIT Project

We aimed to examine: (i) measurement agreement between photoelectric cell system and manual stopwatch timing; (ii) inter-rater agreement between trained and untrained raters using manual stopwatch timing; and (iii) reliability of the 6-m gait speed test to assess motor fitness in...

Longitudinal and reciprocal relationships between physical activity, physical fitness, executive functions, and arithmetic fluency in adolescents

Abstract Background The relationship between physical health and academic outcomes in adolescents is well-established, but the directionality and reciprocal nature of these associations remain unclear. Given the foundational role of mathematical skills in academic success, this s...

Carbon Dioxide Derived Polycarbonate Nanocomposites With Multiwalled Carbon Nanotubes: Conductive and Piezoresistive Materials Towards Sustainable Electronics
