Pollination and seed dispersal determine the spatial pattern of gene flow in plant populations and, for those species relying on pollinators and frugivores as dispersal vectors, animal activity plays a key role in determining this spatial pattern. For these plant species, reported dispersal patterns are dominated by short-distance movements with a significant amount of immigration. However, the...

Projective spaces and hyperquadrics are the simplest projective algebraic varieties, and they can be characterized in many ways. The aim of this paper is to provide a new characterization of them in terms of positivity properties of the tangent bundle (Theorem 1.1). The first result in this direction was Mori’s proof of the Hartshorne conjecture in [Mor79] (see also Siu and Yau [SY80]), that ch...

We show the compactly supported motive of moduli stack degree n rational curves on weighted projective $${\mathcal {P}}(a,b)$$ is mixed Tate type over any base field K with $$\hbox {char}(K) \not \mid a,b$$ and has class $${\mathbb {L}}^{(a+b)n+1}-{\mathbb {L}}^{(a+b)n-1}$$ in Grothendieck ring stacks. In particular, this improves upon results (Han Park Math Ann 375(3–4), 1745–1760, 2019) regar...

lh e tongue is one of the most frequent sites for cancer, representing 26% of all oral cancers and 0.7% of all carcinomas.’ It is also one of the most devastating tumors from a psychosocial standpoint. Although the size, type, and location of tongue lesions determine the mode and aggressiveness of treatment, surgery with or without adjunctive therapy remains the treatment of choice. Regardless ...

In this manuscript we introduce/prove a Z/p meta-abelian form of the birational p-adic Section Conjecture for curves. This is a much stronger result than the usual p-adic birational Section Conjecture for curves, and makes an effective p-adic Section Conjecture for curves quite plausible.

The first step towards the deployment of our learning setup is to guarantee the existence of a measure on the space μk(P)⇥L, where μk(P) = {μk(P ) : P 2 P} ✓ Hk is the set of kernel mean embeddings associated with the measures in P . The following lemma provides such guarantee. This allows the analysis within the rest of this Section on μk(P)⇥ L. Lemma 2. Let (Z, ⌧Z) and (L, ⌧L) be two separabl...

A. Reduction-closed barbed congruence (Section II) Definition 28 (Reduction-closed barbed congruence). Let L be a process calculus, in which a reduction relation −→L and barb predicates ↓a , for each a in a given set of names, have been defined. A relationR on the processes of L is context-closed if PRQ implies C[P ]RC[Q], for each context C of L; the relation is barb-preserving if for any name...
