Bott Periodicity
Bott periodicity plays a fundamental role in the definition and understanding of K-theory, the generalized cohomology theory defined by vector bundles. This paper examines the proof, given by Atiyah and Bott[3], of the periodicity theorem for the complex case. We also describe the long exact …

Bott periodicity for fibred cusp operators
… K-theory of T*Y . It is shown that there is a periodicity, namely the odd and the even homotopy groups are isomorphic among themselves. To obtain this result, one of the important steps is the description of the index of a Fredholm smoothing perturbation of the identity in terms of an …

Migration Towards Periodicity in Systems With Feedback
We study adaptation to the edge of chaos in dynamical systems as caused by feedback mechanisms between the state variables and the parameters. We begin by examining a system know for exhibiting chaotic dynamics and then move on to a spatially extended system. First, we study the effect of low-pass …

Emergency Diesel-Electric Generator Set Maintenance and Test Periodicity
… provide contradictory guidance. As a result, periodicity of emergency diesel-electric generator set maintenance and tests varies considerably in practice. Utilizing the framework proposed and tested by Fehr (2014), this research developed a parametric regression survival model of the …

Periodicity and ruin probabilities for compound non-homogeneous poisson processes
… to a short term periodic environment and the periodicity for its compound claim counting process are discussed. The ruin probabilities of compound non-homogenous Poisson processes with periodic intensity function are also discussed, in which the embedded discrete risk model and the average …

Mining periodicity and object relationship in spatial and temporal data
… I have proposed the very first work to detect periodicity from movement data even if the movement only has rough periodicity and has lots of non-periodic random short-trajectories. I have also systematically studied a broad range of relationship patterns among moving objects in practical …

Higher Dimensional Adeles, Mean-Periodicity and Zeta Functions of Arithmetic Surfaces
… Our weapon of choice is the so-called “mean-periodicity correspondence”, which provides a passage between nicely behaved arithmetic schemes and mean-periodic functions in certain functional spaces. In what follows, there are two major themes. 1. The comparison of the mean-periodicity …

Post-Transplant Root Production, Mortality, and Periodicity of Landscape-Sized Shade Trees
… system on root, shoot, and trunk growth periodicity of balled-and-burlapped (B&B) and pot-in-pot (PIP) sugar maple (Acer saccharum Marsh.), and 3) characterize seasonal patterns of root production and mortality of transplanted sugar maple. No new root growth occurred outside or within the …

The effect of lattice periodicity on the electronic configuration near a metal surface
… a semi-infinite metal. The effect of the lattice periodicity is explicitly taken into account so that the solution in the far interior is consistent with the band structure of the infinite crystal. The solution is sufficiently general to include surface states. The single electron potentials are …

Investigating Diel Periodicity in Export Flux in the Gulf of Mexico Using a Particulate Imaging System
<p>To estimate the diurnal periodicity in the biological pump, a floating array with a marine snow camera system at 150 m depth was used, and particles were imaged at a 40 second interval for a 24 to 30 hour period at five sites in the Gulf of Mexico in June 2017. Each image was processed to …

Seasonal and diel periodicity of Cerambycid beetles in east-central Illinois: the potential for cross attraction
… pheromones already had been identified. Temporal periodicity was characterized with pheromone-baited traps equipped with a mechanism that rotated collection jars at programmable time intervals. Traps captured 1,134 beetles of eight species in three tribes of the Cerambycinae. The study strongly …
