Moduli space of metrics of nonnegative sectional or positive ricci curvature on homotopy realprojective spaces

Dessai, Anand ; Gonzalez-Alvaro, David

In: Transactions of the American Mathematical Society, 2019, p. -

We show that the moduli space of metrics of nonnegative sectional curvature on every homotopy $\R P^5$ has infinitely many path components. We also show that in each dimension $4k+1$ there are at least $2^{2k}$ homotopy $\R P^{4k+1}$s of pairwise distinct oriented diffeomorphism type for which the moduli space of metrics of positive Ricci curvature has infinitely many path components. Examples of...

Boundedness of singular integrals on C1,α intrinsic graphs in the Heisenberg group

Chousionis, Vasileios ; Fässler, Katrin ; Orponen, Tuomas

In: Advances in Mathematics, 2019, vol. 354, p. 106745

We study singular integral operators induced by 3-dimensional Calderón-Zygmund kernels in the Heisenberg group. We show that if such an operator is L2 bounded on vertical planes, with uniform constants, then it is also L2 bounded on all intrinsic graphs of compactly supported C1,α functions over vertical planes. In particular, the result applies to the operator R induced by the...

Diffusing wave microrheology of highly scattering concentrated monodisperse emulsions

Kim, Ha Seong ; Şenbil, Nesrin ; Zhang, Chi ; Scheffold, Frank ; Mason, Thomas G.

In: Proceedings of the National Academy of Sciences, 2019, vol. 116, no. 16, p. 7766–7771

Motivated by improvements in diffusing wave spectroscopy (DWS) for nonergodic, highly optically scattering soft matter and by cursory treatment of collective scattering effects in prior DWS microrheology experiments, we investigate the low-frequency plateau elastic shear moduli G′p of concentrated, monodisperse, disordered oil-in- water emulsions as droplets jam. In such experiments, the...

Deciphering the biology of Cryptophyllachora eurasiatica gen. et sp. nov., an often cryptic pathogen of an allergenic weed, Ambrosia artemisiifolia

Kiss, Levente ; Kovács, Gábor M. ; Bóka, Károly ; Bohár, Gyula ; Bohárné, Krisztina Varga ; Németh, Márk Z. ; Takamatsu, Susumu ; Shin, Hyeon-Dong ; Hayova, Vera ; Nischwitz, Claudia ; Seier, Marion K. ; Evans, Harry C. ; Cannon, Paul F. ; Ash, Gavin James ; Shivas, Roger G. ; Müller-Schärer, Heinz

In: Scientific Reports, 2018, vol. 8, no. 1, p. 10806

A little known, unculturable ascomycete, referred to as Phyllachora ambrosiae, can destroy the inflorescences of Ambrosia artemisiifolia, an invasive agricultural weed and producer of highly allergenic pollen. The fungus often remains undetectable in ragweed populations. This work was conducted to understand its origin and pathogenesis, a prerequisite to consider its potential as a biocontrol...
