Bronchoscope Tip Localization With Learned Airway Constraints and an Open Source Simulator
Advanced Intelligent Systems, EarlyView.BronchoLoc addresses feature‐poor bronchoscopic imaging by combining monocular video with a preoperative CT graph to estimate 3D camera location. A local tracker identifies candidate branches, while a sequence‐aware global module refines the trajectory. Demonstrating sub‐centimeter accuracy across synthetic and phantom datasets, this framework advances

Global interval bifurcation and convex solutions for the Monge-Ampère equations
Electronic Journal of Differential Equations, 2018 Summary: In this article, we establish the global bifurcation result from the trivial solutions axis or from infinity for the Monge-Ampère equations with non-differentiable nonlinearity. By applying the above result, we shall determine the interval of \(\gamma\), in which there exist radial solutions for the following Monge-Ampère equation \[ \begin ...

Phenomenological Study of Backward Bifurcation in Epidemiological Models.
, 2005 This thesis is about the phenomenological study of bifurcations in epidemiologicalmodels, in particular, in backward bifurcation. We consider models that exhibit such bifurcation and also consider the factors that cause them.

The Anatomical Record, EarlyView.Abstract The middle Permian represents a critical interval in therapsid evolution, when gorgonopsians emerged as some of the first specialized apex predators within terrestrial ecosystems. Despite their significance, the early diversification of Gorgonopsia in Gondwana remains poorly understood due to scarcity and fragmentary material.

The Anatomical Record, EarlyView.Abstract An exquisitely preserved, isolated partial petrosal with associated fragmentary stapes is described from the Vastan Lignite Mine (Gujarat, India), dated to the early Eocene (~54.5 Ma). Several anatomical traits (e.g., large petrosal plate; posterolateral entry of the internal carotid artery to the tympanic cavity; bony tubes surrounding the ...

Journal of Differential Equations, 1984 The author studies stability and bifurcation properties of equilibrium solutions of the problem \[ u_t=u_{xx}+f(x,u,u_x,\alpha),\quad u_x(-\infty,t)=u_x(\infty,t)=0, \tag{*} \] with \(\alpha\) being a real bifurcation parameter. To this end, he writes (*) as operator equation \(du/dt=G(u,\alpha)\) in appropriate function spaces, and studies the Fréchet

Bifurcation and stability analysis of aircraft turning manoeuvres [PDF]
, 2008 During ground manoeuvres a loss of lateral stability due to the saturation of the main landing gear tyres can cause the aircraft to enter a skid or a spin. The lateral stability is governed not only by aspects of the gear design, such as its geometry and

Tracing the evolutionary history of the morpho‐anatomy of baculum in primates
The Anatomical Record, EarlyView.Abstract Animal morphology reflects both evolutionary history and present‐day adaptation. Male mammal copulatory structures such as the baculum (penile bone) are ideal for studying these processes because of their complexity and high interspecific variability. In primates, however, research has focused mostly on baculum length.

Arthritis &Rheumatology, EarlyView.Objective Systemic lupus erythematosus (SLE) is characterized by type I interferon (IFN) signaling and adaptive immune dysregulation. We previously identified hypomethylation of HLA‐DRB1 and STAT1 in SLE CD8+ T cells, enabling aberrant IFN‐driven HLA‐DRB1 expression and expansion of a distinct CD8+ T cell subset. This study characterized CD8+ HLA‐DRB1+
