Modeling the Effects of Positive and Negative Feedback in Kidney Blood Flow Control
This paper models the interactions of three key feedback mechanisms that regulate blood flow in the mammalian kidney: (1) the myogenic response, triggered by blood pressure in the afferent arteriole; (2) tubuloglomerular ...
An Application of Abstract Algebra to the Neural Code for Sound Localization in the Barn Owl
Patterns of neural firing can be viewed as a binary code with each neuron as a bit, with neurons which actively fire in response to a stimulus associated to a 1 and those which do not fire associated to a 0. In previous ...
Morphisms with Only Mild Singular Fibers and Bertini Theorems over Finite Fields
We compute the asymptotic density of non-singular hypersurfaces of bidegree (3, d) in P^n×P^1 with only mild singular fibers over P^1 over a finite field F_q for n = 1, 2. When n = 1 and char F_q > 2, this asymptotic density ...
A maximum entropy-based approach for the description of the conformational ensemble of calmodulin from paramagnetic NMR
Characterizing protein dynamics is an essential step towards a better understanding of protein function. Experimentally, we can access information about protein dynamics from paramagnetic NMR data such as pseudocontact shifts, ...
