K-homology and K-theory for the lamplighter groups of finite groups
(London Mathematical Society, 2017-08)
Let F be a finite group. We consider the lamplighter group L = F ≀ Z over F. We prove that L has a classifying space for proper actions EL which is a complex of dimension 2.We use this to give an explicit proof of the ...

On the Muskat problem: global in time results in 2D and 3D
(Johns Hopkins University Press, 2016-12)
This paper considers the three dimensional Muskat problem in the stable regime. We obtain a conservation law which provides an L2 maximum principle for the fluid interface. We also show global in time existence for strong ...

Stress-related biomolecular condensates in plants
(American Society of Plant Biologists, 2023-09)
Biomolecular condensates are membraneless organelle-like structures that can concentrate molecules and often form through liquid-liquid phase separation. Biomolecular condensate assembly is tightly regulated by developmental ...

Variation in upper thermal tolerance among 19 species from temperate wetlands
(Elsevier, 2021)
Communities usually possess a multitude of interconnected trophic interactions within food webs. Their regulation generally depends on a balance between bottom-up and top-down effects. However, if sensitivity to temperature ...

Absence of splash singularities for surface quasi-geostrophic sharp fronts and the Muskat problem
(National Academy of Sciences (United States), 2014)
In this paper, for both the sharp front surface quasi-geostrophic equation and the Muskat problem, we rule out the “splash singularity” blow-up scenario; in other words, we prove that the contours evolving from either of ...

A glimpse into the basis of vision in the kingdom Mycota
(Elsevier, 2010)
Virtually all organisms exposed to light are capable of sensing this environmental signal. In recent years the photoreceptors that mediate the ability of fungi to " see" have been identified in diverse species, and ...

Multiple Mechanisms in Proton-Induced Nucleon Removal at ∼100 MeV/Nucleon
(American Physical Society, 2023)
We report on the first proton-induced single proton- and neutron-removal reactions from the neutron-deficient O14 nucleus with large Fermi-surface asymmetry Sn-Sp=18.6 MeV at ∼100 MeV/nucleon, a widely used energy regime ...
