Decision Theory and Proof Standards for Future Crimes: Possible Uses and Open Questions

Behavioral Sciences &the Law, EarlyView.
ABSTRACT What should be the proof standard for applying preventive criminal sanctions based on an establishment of risk of reoffending? This is an open question in legal systems around the world. Various authors suggest that we can answer it by using decision theory. This approach conceptualises the proof standard as a probabilistic threshold. A person

Dynamics analysis for a discrete dynamic competition model

Advances in Difference Equations, 2019
In this paper, the dynamics of a discrete market share attraction model are investigated. It shows that the system can undergo flip bifurcation and chaos.

A Modified Technique for Converting Retrograde Femoral Artery Access to Antegrade Access With the Assistance of a Long Sheath

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Percutaneous femoral access serves as the cornerstone of endovascular therapy of lower extremity arterial disease. In complex cases, the arterial disease of lower extremity are involve in ipsilateral iliac artery pathology, which conventional treatment strategies typically require multiple punctures or staged procedures.

Pattern Formation Mechanisms of Spatiotemporally Discrete Activator–Inhibitor Model with Self- and Cross-Diffusions

Fractal and Fractional
In this paper, we aim to solve the issue of pattern formation mechanisms in a spatiotemporally discrete activator–inhibitor model that incorporates self- and cross-diffusions.

Standardized MRI‐Based Quantification of Epicardial Adipose Tissue Volume: Reproducibility and Agreement With Cardiac Computed Tomography

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Epicardial adipose tissue volume (EATV) is increasingly recognized as a cardiometabolic risk marker associated with adverse outcomes. The most established approach for EATV quantification is cardiac computed tomography (CT). MRI offers a radiation‐free alternative allowing simultaneous assessment of myocardial function and tissue ...

Analyzing Bifurcations and Optimal Control Strategies in SIRS Epidemic Models: Insights from Theory and COVID-19 Data

Mathematical and Computational Applications
This study investigates the dynamic behavior of an SIRS epidemic model in discrete time, focusing primarily on mathematical analysis. We identify two equilibrium points, disease-free and endemic, with our main focus on the stability of the endemic state.

The Chaos Dynamic of Multiproduct Cournot Duopoly Game with Managerial Delegation

Discrete Dynamics in Nature and Society, 2014
Although oligopoly theory is generally concerned with the single-product firm, what is true in the real word is that most of the firms offer multiproducts rather than single products in order to obtain cost-saving advantages, cater for the diversity of ...

Autonomous Velocity Encoding (VENC) Selection Improves Precision of Quantitative Flow Measurement

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background The optimal velocity encoding limit (VENC) in phase contrast MRI is subject‐specific because it depends on peak flow rate and the presence of flow jets. Currently, VENC is set manually with limited prior knowledge of the peak velocity. Setting the correct VENC might improve measurement precision or shorten scan times.

Utility of Combining FIESTA‐C and MENSA for Facial Nerve Identification in Parotid Gland Surgery

The Laryngoscope, EarlyView.
This study evaluated the role of FIESTA‐C and MENSA in facial nerve identification and tumor localization in parotid gland surgery. The combination of FIESTA‐C and MENSA improved the accuracy of facial nerve identification and tumor localization compared to either sequence alone.
