For my grandfather Heinrich, who passed away during the final days of the preparation of this thesis.

The celebrated Franck-Hertz experiment is reinterpreted by analogy with the Glimmentladung experiment, formerly performed by Heinrich Hertz.

Palaeoclimate records have revealed the presence of millennial-scale climate oscillations throughout the last glacial period1. Six periods of extreme cooling in the Northern Hemisphere—known as Heinrich events—were marked by an enhanced discharge of icebergs into the North Atlantic Ocean2,3, increasing the deposition of ice-rafted debris2. Increased sliding at the base of ice sheets as a result...

Bayesian networks are a formal graphical language to express the joint distribution of a system or phenomenon in terms of random variables and their conditional dependencies in a directed graph [Heinrich, 2005]. A generative model is a bayesian network which provides an intuitive description of an observed phenomenon which states how observations could have been generated by realizations of ran...

Eucosma Hübner is the largest genus in the Tortricidae with more than 290 named species. Historically, there has been confusion about the assignment of species to Eucosma and related genera, a problem which is perpetuated by the lack of a type specimen for the type species, E. circulana Hübner. Here we designate a neotype for E. circulana following analysis of eight North American species havin...

The first major atlas ofworldwide thematic maps was completed in 1848, consisting of some 90 maps in two volumes. Created by Heinrich Berghaus at the Geographische Kunstschule in Potsdam, the Physikalischer Atlas (Physical Atlas) reflected the intense interest and activity in mapping a wide range of natural phenomena in the first part of the nineteenth century. The intent of this essay is to co...

The term benthos, coined by the German naturalist Ernst Heinrich Philipp August Haeckel in 1891 [...]

We discuss three examples of bimolecular mass-action systems with species, due to Feinberg, Berner, Heinrich, and Wilhelm. Each system has a unique positive equilibrium which is unstable for certain rate constants then exhibits stable limit cycles, but no chaotic behaviour. For some in the Feinberg--Berner system, equilibrium, an unstabe cycle, cycle coexist. All networks are minimal sense. By ...
