Selection maintains floral color polymorphism in scarlet paintbrush, Castilleja coccinea, reflecting combined ecological factors

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Evolutionary theory predicts polymorphism should be rare; however, intraspecific variation in floral color is common and can be attributed to genetic drift, plasticity, or variable selection. Examining floral color polymorphism both within contact zones and across a species' range can reveal the mechanisms maintaining this variation ...

Hardy-Sobolev spaces of higher order associated to Hermite operator

open access: yesCommunications in Analysis and Mechanics
Let $ L = -\Delta+|x|^2 $ be the Hermite operator on $ \mathbb R^{d} $, where $ \Delta $ is the Laplacian on $ \mathbb R^{d} $. In this paper, we will consider the Hardy-Sobolev spaces of higher order associated with $ L $.

𝑝-Carleson Measures for a Class of Hardy-Orlicz Spaces

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2011
An alternative interpretation of a family of weighted Carleson measures is used to characterize 𝑝-Carleson measures for a class of Hardy-Orlicz spaces admitting a nice weak factorization.

An elastic segment of the whisker shaft enables coding of the whisking phase via whisker torsion in rats and mice

open access: yesThe 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 ...

On Hardy type spaces in strictly pseudoconvex domains and the density, in these spaces, of certain classes of singular functions

open access: yes, 2019
In this paper we prove generic results concerning Hardy spaces in one or several complex variables. More precisely, we show that the generic function in certain Hardy type spaces is totally unbounded and hence non-extentable, despite the fact that these ...

“You're this person who's providing light”: Embodied responses to information loss and transition within LGBTQIA+ communities

open access: yesJournal of the Association for Information Science and Technology, EarlyView.
Abstract This paper reports on findings from 15 semi‐structured interviews with LGBTQIA+ individuals within the United States who have experienced the loss of one or more LGBTQIA+ information spaces. The paper specifically focuses on how such losses occurred and the information transitions experienced by the participants in response to this loss ...

Martingale transforms in martingale Hardy spaces with variable exponents

open access: yesAIMS Mathematics
In this paper, we considered the boundedness of Burkholder's martingale transforms for martingale Hardy spaces with variable exponents. In addition, through martingale transforms, some characterizations of predictable variable exponent martingale Hardy ...

Fractional differentiation composition operators from Sp spaces to Hq spaces [PDF]

open access: yesMathematica Moravica
Let Sp be the space of functions analytic on the unit disk and whose derivatives belong to the Hardy space. In this article, we investigate the boundedness and compactness of the fractional differentiation composition operators from Sp spaces into Hardy ...

Hardy spaces and divergence operators on strongly Lipschitz domains in $R^n$

open access: yes, 2002
Let $\Omega$ be a strongly Lipschitz domain of $\reel^n$. Consider an elliptic second order divergence operator $L$ (including a boundary condition on $\partial\Omega$) and define a Hardy space by imposing the non-tangential maximal function of the ...

“Basic human things”: Investigating vehicle residents' continually fractured (information) landscapes

open access: yesJournal of the Association for Information Science and Technology, EarlyView.
Abstract This ethnographic study explores vehicle residents' information practices in the United States (US). Vehicle residents are people whose primary means of housing is a vehicle. This work builds on previous research encompassing transitions and fractured (information) landscapes. Using fractured information landscapes as the theoretical framework,
