High-resolution temporal contact networks are useful ingredients for realistic epidemic simulations. Existing solutions typically rely either on empirical studies that capture fine-grained interactions via Bluetooth or wearable sensors in confined settings or on large-scale simulation frameworks that model entire populations using generalized assumptions. However, for most realistic modeling of epidemic spread and the evaluation of countermeasures, there is a critical need for highly resolved, temporal contact networks that encompass multiple venues without sacrificing the intricate dynamics of real-world contacts. This paper presents an integrated approach for generating such networks by coupling Bayesian-optimized human mobility models (HuMMs) with a state-of-the-art epidemic simulation framework. Our primary contributions are twofold: First, we embed empirically calibrated HuMMs into an epidemic simulation environment to create a parameterizable, adaptive engine for producing synthetic, high-resolution, population-wide temporal contact network data. Second, we demonstrate through empirical evaluations that our generated networks exhibit realistic interaction structures and infection dynamics. In particular, our experiments reveal that while variations in population size do not affect the underlying network properties-a crucial feature for scalability-altering location capacities naturally influences local connectivity and epidemic outcomes. Additionally, sub-graph analyses confirm that different venue types display distinct network characteristics consistent with their real-world contact patterns. Overall, this integrated framework provides a scalable and empirically grounded method for epidemic simulation, offering a powerful tool for generating and simulating contact networks.

Utilising mpox case data from Burundi between August 2024 and April 2025, we calibrated a mathematical model to quantify the temporal trends of clade Ib monkeypox virus transmission. The model outputs indicated a declining overall transmission trend. Children aged 0-4 and 5-9 years were estimated to be at higher risk of infection compared to older age groups, while sexual contact was inferred to contribute up to 50% of the overall transmission.

Introduction: Several sub-Saharan African countries are launching malaria vaccination programmes for children. We assessed how attitudes to malaria vaccination for children could be better understood by considering the individual dynamics of COVID-19 vaccine intention/uptake over the 2021-2023 campaigns, with a view to highlighting barriers likely to affect malaria vaccine uptake.
Methods: We conducted a six-wave telephone-based survey of 600 randomly selected Senegalese households.

Objective: Cinnamon-induced contact stomatitis (CCS) is a hypersensitivity reaction associated with cinnamon-containing products (CCPs). We performed a retrospective study of 74 cases of CCS induced by chewing gums or candies and reviewed the literature.
Materials And Methods: This is a retrospective study of CCS cases, diagnosed during 2010-2025, characterised by temporal association of lesions with the consumption of cinnamon-containing chewing gums or candies; lesion's resolution after discontinuation of those CCPs; and absence of recurrence as long as those CCPs were not re-used.

Since Hans Driesch's pioneering work in 1891, it has been known that animal embryos can develop into complete individuals even when divided. However, the developmental processes and molecular mechanisms enabling this self-organization remain poorly understood. In this study, we revisit Driesch's experiments by examining the development of isolated 2-cell stage blastomeres in the sea urchin, Hemicentrotus pulcherrimus.

Introduction: Deficits in lower-limb muscle strength and altered gait mechanics are common after anterior cruciate ligament reconstruction (ACL). While isokinetic strength testing is widely accepted in return-to-sport assessment, the role of plantar pressure analysis in detecting compensatory gait strategies remains underexplored.
Methods: This study included 10 male patients (30.
