American Journal of Botany, EarlyView.Abstract Premise Flowers that present their anthers and stigma in close proximity can achieve precise animal‐mediated pollen transfer, but risk self‐pollination. One evolutionary solution is reciprocal herkogamy. Reciprocity of anther and style positions among different plants (i.e., a genetic dimorphism) is common in distylous plants, but very rare in

Multipolar potentials and weighted Hardy inequalities
Discrete and Continuous Dynamical Systems - S\begin{abstract} In this paper we state the following weighted Hardy type inequality for any functions $φ$ in a weighted Sobolev space and for weight functions $μ$ of a quite general type \begin{equation*} c_{N,μ} \int_{\R^N}V\,φ^2μ(x)dx\le \int_{\R^N}|\nabla φ|^2μ(x)dx +C_μ\int_{\R^N}W φ^2μ(x)dx, \end{equation*} where $V$ is a multipolar potential and

The Anatomical Record, EarlyView.An elastic segment was found in the basal part of the whisker shaft in rats and mice. Application of force to the whisker bulb of isolated follicles caused bending and twisting of this segment. Active whisker movements deform this segment, causing whisker shaft deflection and selective activation of mechanoreceptors at different phases of whisking ...

The Anatomical Record, EarlyView.Abstract The Pleistocene is a key period for understanding the evolutionary history and palaeobiogeography of the European rabbit (Oryctolagus cuniculus). The species was first documented in southeastern Iberia at the beginning of the Middle Pleistocene and appears to have rapidly spread throughout Southwestern Europe, where it was found in numerous ...

Study of singular elliptic equations with mixed boundary conditions and nonlocal source terms
Electronic Journal of Qualitative Theory of Differential EquationsIn this article, we study the generalized solutions for singular elliptic equations with mixed boundary conditions, a nonlocal source term and a Hardy potential.

The Anatomical Record, EarlyView.Abstract Intermittent hypobaric hypoxia (IHH) enhances oxygen transport, muscle metabolism, and cardiovascular health; however, the combined effects of hypobaria and cold are less well understood. Exposure to these stressful environmental factors, even intermittently, can affect skeletal muscle due to its plasticity, thereby altering its metabolic and ...

Weak solutions of semilinear elliptic equations with Leray-Hardy potentials and measure data
Mathematics in Engineering, 2019 We study existence and stability of solutions of $$ -\Delta u +\frac{\mu}{|x|^{2 }}u+ g(u)= ν \text{ in }\Omega,\ \ \ u=0\text{ on } ∂Ω,$$ where $\Omega$ is a bounded, smooth domain of $\mathbb{ R}^N$, $N\geq 2$, containing the origin, $\mu\geq-\frac{(
