Topological entropy of transitive dendrite maps [PDF]
, 2012 We show that every dendrite satisfying the condition that no subtree of it contains all free arcs admits a transitive, even exactly Devaney chaotic map with arbitrarily small entropy. This gives a partial answer to a question of Baldwin from 2001.Comment:

Metrics and spectral triples for Dirichlet and resistance forms [PDF]
, 2013 The article deals with intrinsic metrics, Dirac operators and spectral triples induced by regular Dirichlet and resistance forms. We show, in particular, that if a local resistance form is given and the space is compact in resistance metric, then the ...

Branching dendrites with resonant membrane: a “sum-over-trips” approach [PDF]
, 2007 Dendrites form the major components of neurons. They are complex branching structures that receive and process thousands of synaptic inputs from other neurons.

Defining a standard and weighted mathematical index for maturation of dendritic cells [PDF]
Immunology, 2017 SummaryThe concept of dendritic cell (DC) maturation generally refers to the changes in morphology and function of DCs. Conventionally, DC maturity is based on three criteria: loss of endocytic ability, gain of high‐level capacity to present antigens and induce proliferation of T cells, and mobility of DCs toward high concentrations of CCL19 ...

Dissociation of HIV-1 from follicular dendritic cells during HAART: Mathematical analysis [PDF]
Proceedings of the National Academy of Sciences, 1999 Follicular dendritic cells (FDC) provide a reservoir for HIV type 1 (HIV-1) that may reignite infection if highly active antiretroviral therapy (HAART) is withdrawn before virus on FDC is cleared. To estimate the treatment time required to eliminate HIV-1 on FDC, we develop deterministic and stochastic models for the reversible binding of HIV-1 to FDC ...

Dendritic Signals Command Firing Dynamics in a Mathematical Model of Cerebellar Purkinje Cells [PDF]
Biophysical Journal, 2010 Dendrites of cerebellar Purkinje cells (PCs) respond to brief excitations from parallel fibers with lasting plateau depolarizations. It is unknown whether these plateaus are local events that boost the synaptic signals or they propagate to the soma and directly take part in setting the cell firing dynamics.

The formation of freckles in binary alloys [PDF]
, 1985 This paper presents a synopsis of some recent work, still in progress, aimed at elucidating a quantitative explanation of the processes by which flow chimneys form when certain types of alloys are directionally solidified. If (for example) light fluid is

Mathematical study of a nonlinear neuron multi-dendritic model [PDF]
Quarterly of Applied Mathematics, 1994 A mathematical model of potential spreading along neuron dendrites is proposed to describe the synaptic transmissions in the so-called cerebellar granule cells, which consist of a nearly spherical soma emitting a finite number of dendrites. The model accounts for the nonlinear dependence of the NMDA receptors, located at the virtual ends of any ...

A fully implicit, fully adaptive time and space discretisation method for phase-field simulation of binary alloy solidification [PDF]
, 2007 A fully-implicit numerical method based upon adaptively refined meshes for the simulation of binary alloy solidification in 2D is presented. In addition we combine a second-order fully-implicit time discretisation scheme with variable steps size ...

A Mathematical Modelling of Initiation of Dendritic Cells-Induced T Cell Immune Response [PDF]
International Journal of Biological Sciences, 2019 Dendritic cells (DCs) are the most potent specialized antigen-presenting cells as now known, which play a crucial role in initiating and amplifying both the innate and adaptive immune responses. Immunologically, the motilities and T cell activation capabilities of DCs are closely related to the resulting immune responses. However, due to the complexity
