The unpredictably eruptive dynamics of spruce budworm populations in eastern Canada
Population Ecology, EarlyView.We examine historical population data for spruce budworm from several locations through the period 1930–1997, and use density‐dependent recruitment curves to test whether the pattern of population growth over time is more consistent with Royama's (1984; Ecological Monographs 54:429–462) linear R(t) model of harmonic oscillation at Green River New ...

The Abduction of the Atom: An Exercise in Hypothesizing
Informal Logic, 1995 The paper attempts to schematize, in the form of abductive inferences, the major changes in the developing picture of the atom during the modem period of scientific investigation.

About two countable families in the finite sets of the Collatz Conjecture
Ratio Mathematica, 2021 With t∊ℕ we define the sets Kt and Kt*containing all positive integers that converge to 1 in t iterations in the form of Collatz algorithm. The following are the properties of the { Kt }t∊ℕ and { Kt* }t∊ℕ : countability, empty intersection between the

The proof of the l 2 Decoupling Conjecture
, 2015 We prove the l 2 Decoupling Conjecture for compact hypersurfaces with positive denite second fundamental form and also for the cone. This has a wide range of important consequences.

Sharpening the weak gravity conjecture with dimensional reduction [PDF]
, 2015 A bstractWe investigate the behavior of the Weak Gravity Conjecture (WGC) under toroidal compactification and RG flows, finding evidence that WGC bounds for single photons become weaker in the infrared.

Algebraic & Geometric Topology, 2003 We prove that the homotopy class of a Morin mapping f: P^p --> Q^q with p-q odd contains a cusp mapping. This affirmatively solves a strengthened version of the Chess conjecture [DS Chess, A note on the classes [S_1^k(f)], Proc. Symp. Pure Math., 40 (1983) 221-224] and [VI Arnol'd, VA Vasil'ev, VV Goryunov, OV Lyashenko, Dynamical systems VI ...

Network topology drives population temporal variability in experimental habitat networks
Population Ecology, EarlyView.Habitat patches connected by dispersal pathways form habitat networks. We explored how network topology affects population outcomes in laboratory experiments using a model species (Daphnia carinata). Central habitat nodes in complex lattice networks exhibited lower temporal variability in population sizes, suggesting they support more stable ...

50 Years of the Golomb--Welch Conjecture
, 2017 Since 1968, when the Golomb--Welch conjecture was raised, it has become the main motive power behind the progress in the area of the perfect Lee codes. Although there is a vast literature on the topic and it is widely believed to be true, this conjecture
