Phase transition in a long-memory log-Gaussian Cox process

We study a stochastic point process with power-law temporal correlations driven by hidden variables. We show that a generalized Merton type model under an exponential-tail asset assumption—obtained by replacing the Gaussian cumulative distribution function with a logistic CDF— to...

Performance and Economic Boundary Analysis of an Integrated PV–Solar-Thermal–Battery–Hydrogen System for a Cold-Climate Dwelling: A Case Study in Northern Japan

Cold-climate dwellings can face coincident electricity and domestic hot-water shortfalls in winter, when solar availability is at its lowest. This study evaluates an integrated residential system for Aomori, Japan, combining photovoltaics, evacuated-tube solar water heating, and...

Moderate aortic stenosis identified during intensive care admission for a non-cardiac primary diagnosis and 90-day mortality: a retrospective cohort study using the MIMIC-IV echocardiography database

Abstract Background Moderate aortic stenosis is associated with reduced survival in ambulatory cardiology populations, but its prognostic significance when identified during an intensive care admission for a non-cardiac primary diagnosis is unknown. We examined its association wi...

Sarcopenia affects the outcomes and tolerability in patients with interstitial lung disease receiving nintedanib: a retrospective study

Nintedanib is approved for various interstitial lung diseases (ILDs). Although sarcopenia, which is characterized by a loss of skeletal muscle mass, is known to affect the outcome of ILD, the outcome of patients with sarcopenia receiving nintedanib remains unclear. Fifty-six pati...
