Bifurcation of Nonlinear Equations: II. Dynamic Bifurcation [PDF]
[Part 1 appeared ibid., 155--178 (1994; Zbl 1095.47027), see the preceding review.] The authors study dynamic bifurcation when the eigenvalue of the linearized problem has algebraic multiplicity one or two. As in the first part of the work for steady state bifurcations, their key idea is to analyze precisely the effect of the higher-order nondegenerate

Modelling stem cell differentiation related processes—A practical overview for biologists
Stem cell differentiation is complex and difficult to control experimentally. This review introduces suitable computational modelling approaches that can support stem cell research, from mechanistic ODE and abstract models to multiscale and deep learning methods.

Endovascular repair of aortoiliac aneurysmal disease with the helical iliac bifurcation device and the bifurcated-bifurcated iliac bifurcation device [PDF]
Iliac branch device (IBD) treatment of common and internal iliac artery (CIA and IIA) aneurysms has been controversial in the context of available embolization techniques or off-label adjunctive procedures. Two devices exist, a straight IBD (S-IBD) and a helical IBD (H-IBD).

Time‐resolved X‐ray solution scattering captures how proteins change shape in real time under near‐native conditions. This article presents a practical workflow for light‐triggered TR‐XSS experiments, from data collection to structural refinement. Using a calcium‐transporting membrane protein as an example, the approach can be broadly applied to study ...

Possibility of Atherosclerosis in an Arterial Bifurcation Model
Introduction: Arterial bifurcations are susceptible locations for formation of atherosclerotic plaques. In the present study, steady blood flow is investigated in a bifurcation model with a non-planar branch.

Epilepsy‐Associated Variants of a Single SCN1A Codon Exhibit Divergent Functional Properties
ABSTRACT Objective Pathogenic variants in SCN1A, which encodes the voltage‐gated sodium channel NaV1.1, are associated with multiple epilepsy syndromes exhibiting a range of clinical severity. SCN1A variants are reported in different syndromes, including Dravet syndrome, which is associated with loss‐of‐function, whereas neonatal/infantile‐onset ...

We present in this paper an investigation on a discrete predator-prey system with Crowley-Martin type functional response to know its complex dynamics on the routes to chaos which are induced by bifurcations.

Dynamics of A Discrete-Time Ecogenetic Predator-Prey Model
This article considers a discrete-time model of two genetically distinguished predator population and one prey population. The existence and nature of the boundary and positive fixed points are examined.

Let f_t , where t is close to zero, be an analytic family of plane-to-plane mappings. There are presented effective methods of computing the number of cusps of f_t emanating from the origin and having positive/negative cusp degree.
