Radiation dose estimation with time-since-exposure uncertainty using the γ -H2AX biomarker
To predict the health effects of accidental or therapeutic radiation exposure, one must estimate the radiation dose that person received. A well-known ionising radiation biomarker, phosphorylated γ-H2AX protein, is used ...
The precise representative for the gradient of the Riesz potential of a finite measure
Given a finite nonnegative Borel measure (Formula presented.) in (Formula presented.), we identify the Lebesgue set (Formula presented.) of the vector-valued function (Formula presented.) for any order (Formula presented.). ...
Evolution of the G Matrix under Nonlinear Genotype-Phenotype Maps
The G matrix is a statistical summary of the genetic basis of a set of traits and a central pillar of quantitative genetics. A persistent controversy is whether G changes slowly or quickly over time. The evolution of G is ...
Optimal Stein-type goodness-of-fit tests for count data
Common count distributions, such as the Poisson (binomial) distribution for unbounded (bounded) counts considered here, can be characterized by appropriate Stein identities. These identities, in turn, might be utilized to ...
The criticality of reversible quadratic centers at the outer boundary of its period annulus
This paper deals with the period function of the reversible quadratic centers Xν=−y(1−x)∂x+(x+Dx2+Fy2)∂y, where ν=(D,F)∈R2. Compactifying the vector field to S2, the boundary of the period annulus has two connected components, ...
Pointwise periodic maps with quantized first integrals
We describe the global dynamics of some pointwise periodic piecewise linear maps in the plane that exhibit interesting dynamic features. For each of these maps we find a first integral. For these integrals the set of values ...
A b-symplectic slice theorem
In this article, motivated by the study of symplectic structures on manifolds with boundary and the systematic study of b -symplectic manifolds started in Guillemin, Miranda, and Pires Adv. Math. 264 (2014), 864–896, we ...
Loop space homology of a small category
In a 2009 paper, Dave Benson gave a description in purely algebraic terms of the mod p homology of Ώ(BG∧p), whenGis a finite group,BG∧p is the p-completion of its classifying space, and Ώ(BG∧p)is the loop space ofBG∧p. The ...
Geometric quantization via cotangent models
In this article we give a universal model for geometric quantization associated to a real polarization given by an integrable system with non-degenerate singularities. This universal model goes one step further than the ...
Reproduction number for an age of infection structured model
We study the basic reproduction number (R0) in an epidemic model where infected individuals are initially asymptomatic and structured by the time since infection. At the beginning of an epidemic outbreak the computation ...
Microrheometer for biofluidic analysis: Electronic detection of the fluid‐front advancement
The motivation for this study was to develop a microdevice for the precise rheological characterization of biofluids, especially blood. The method presented was based on the principles of rheometry and fluid mechanics at ...
Simplicity of fusion systems of finite simple groups
We determine for which known finite simple groups G and which primes p the p-fusion system of G is simple. This means first collecting together the results that were already known (and correcting two errors made in an ...
A proof of Carleson's ε2-conjecture
In this paper we provide a proof of the Carleson ε2-conjecture. This result yields a characterization (up to exceptional sets of zero length) of the tangent points of a Jordan curve in terms of the finiteness of the ...
miRecSurv Package: Prentice-Williams-Peterson Models with Multiple Imputation of Unknown Number of Previous Episodes
Left censoring can occur with relative frequency when analyzing recurrent events in epidemiological studies, especially observational ones. Concretely, the inclusion of individuals that were already at risk before the ...
Orbitally symmetric systems with applications to planar centers
We present a generalization of the most usual symmetries in differential equations known as the time-reversibility and the equivariance ones. We check that the typical properties are also valid for the new definition that ...
Uniqueness of Curvature Measures in Pseudo-Riemannian Geometry
The recently introduced Lipschitz–Killing curvature measures on pseudo-Riemannian manifolds satisfy a Weyl principle, i.e. are invariant under isometric embeddings. We show that they are uniquely characterized by this ...
Non-bifurcation of critical periods from semi-hyperbolic polycycles of quadratic centres
In this paper we consider the unfolding of saddle-node parametrized by with and in an open subset of and we study the Dulac time of one of its hyperbolic sectors. We prove (theorem 1.1) that the derivative tends to as ...
Why call it developmental bias when it is just development?
The concept of developmental constraints has been central to understand the role of development in morphological evolution. Developmental constraints are classically defined as biases imposed by development on the distribution ...
Quantifying the under-reporting of uncorrelated longitudal data: the genital warts example
Background: Genital warts are a common and highly contagious sexually transmitted disease. They have a large economic burden and affect several aspects of quality of life. Incidence data underestimate the real occurrence ...
New statistical model for misreported data with application to current public health challenges
The main goal of this work is to present a new model able to deal with potentially misreported continuous time series. The proposed model is able to handle the autocorrelation structure in continuous time series data, which ...
