Direct SMBH Formation Driven by Runaway Stellar Collisions in Globally Unstable Stellar Systems

Astronomische Nachrichten, EarlyView.
ABSTRACT The fueling problem addresses the ultimate fate of the reservoirs of gas and stars driven into the deepest gravitational potential wells of galaxies, thus it may contain the Universe's densest concentrations of gas and stars. This raises a key question: does the infalling material collapse directly into a supermassive black hole, or can it ...

Animal empathy reconsidered: a multidimensional profile account

Biological Reviews, EarlyView.
ABSTRACT Empathy is the glue that holds societies together and yet several fundamental questions about empathy persist. What is empathy (the definitional question)? Is it uniquely human and, if not, which nonhuman animals possess empathy (the distribution question)? Which type or quality of empathy is realized in different species (the quality question)

Spatial Dynamics of an Imprecise Epidemic Model With Beddington–DeAngelis Incidence Rate

Discrete Dynamics in Nature and Society
Due to the incomplete information caused by measurements, data collection, and initial value determination processes, imprecise parameters in epidemic modeling should be taken into account.

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

Boundary Value Problem of Magnetically Insulated Diode: Existence of Solutions and Complex Bifurcation

Известия Иркутского государственного университета: Серия "Математика"
The paper focuses on the stationary self-consistent problem of magnetic insulation for a vacuum diode with space-charge limitation, described by a singularly perturbed Vlasov-Maxwell system of dimension 1.5. The case of insulated diode when the electrons

Bilateral Symmetry and Variation of Recurrent Laryngeal Nerve and Inferior Thyroid Artery Patterns: An Intraoperative Study of 150 Nerves

Clinical Anatomy, EarlyView.
ABSTRACT The anatomical relationship of the inferior thyroid artery (ITA) and the recurrent laryngeal nerve (RLN) is highly variable. This study aims to evaluate bilateral RLN branching patterns and their relationship to the ITA within the same patient, predicting contralateral anatomical variations and ultimately reducing intraoperative risk of RLN ...

Redefining the Surface Anatomy of Major Abdominal Structures in an Adult Population: A Computed Tomography Evaluation

Clinical Anatomy, EarlyView.
ABSTRACT Inconsistencies exist in anatomy and clinical reference texts regarding the vertebral levels of major abdominal structures. Accurate surface anatomy is essential for diagnostic interpretation and interventional procedures, yet little is known about how health status or pathology may influence the vertebral relationships of abdominal organs ...

VERMONT μQFR: Diagnostic Accuracy of Murray Law‐Based 2D‐μQFR Compared to 3D‐μQFR and vFFR

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Murray law‐based quantitative flow ratio (μQFR) is an angiography‐derived physiological index that utilizes a single angiographic projection with artificial intelligence‐guided vessel segmentation. Aims To evaluate the diagnostic accuracy and time efficacy of 2D‐μQFR against wire‐based fractional flow reserve (FFR ≤ 0.80), compare ...

Evaluation of Treatment Response of Calcified Nodules and Nodular Calcified Lesions Using Mean Density on Coronary Computed Tomography Angiography

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Calcified nodules (CN) and nodular calcifications (NC) present significant challenges during percutaneous coronary intervention (PCI) because of their protruding morphology and high rigidity, which often result in inadequate stent expansion and suboptimal procedural outcomes.

Global bifurcation for semilinear eigenvalue problems involving nonlocal terms

Electronic Journal of Differential Equations
We investigate global bifurcation phenomenon for a class of semilinear eigenvalue problems involving nonlocal terms. Under certain assumptions, we demonstrate the existence of a global continuum emanating from the first eigenvalue of the unperturbed ...
