Patterns of diversification and contact
2020This chapter presents the main questions raised in this book, as well as introducing some key notions that play a role in their answering. How did languages spread across the globe, and what are the implications for our understanding of human prehistory?

Contact shot with unusual soot pattern
Forensic Science International, 2005In a suicidal shot to the temple two roundish zones of powder soot blackening were found above the entrance wound. The paired zones of powder soot blackening were caused by two gas outlets located on the upper side of the muzzle end of the weapon used (converted blank cartridge pistol of make Rhöner).

Patterns of code-switching and patterns of language contact
Lingua, 1995Abstract Studies of code-switching over the past two decades have tended to concentrate on two parameters: grammatical constraints governing switching and the rhetorical or discoursal functions individual switches may fulfil. This paper draws attention to some other factors which may influence the patterns of switching favoured by particular ...

Contact patterns of equal nonoverlapping spheres
Graphs and Combinatorics, 1985A contact pattern is defined as a graph with the vertex set corresponding to the set of nonoverlapping spheres in Euclidean space, where two vertices are adjacent when corresponding spheres touch each other. One can see that any finite graph G is a contact pattern in some n-space \(E^ n\).

Cross-Reactivity Patterns of Contact-Sensitizing Methacrylates
Toxicology and Applied Pharmacology, 1998Methacrylates are well-known contact sensitizers with increasing frequency of contact leading to occupational skin disease. Here, we developed an animal model to facilitate studies on the sensitizing capacities and cross-reactivity patterns between four clinically most important allergens: methacrylate (MMA), 2-hydroxyethyl methacrylate (2-HEMA), 2 ...

Unusual Patterns in Contact Dermatitis: Medicaments
Dermatologic Clinics, 2009Allergic contact dermatitis to topical medicaments occurs often. Common medicaments associated with allergic contact dermatitis include topically applied antibiotics, antihistamines, nonsteroidal antiinflammatory drugs, anesthetics, and corticosteroids.

On biological pattern formation by contact inhibition
2012 American Control Conference (ACC), 2012Many patterning events in multi-cellular organisms rely on cell-to-cell contact signaling. We study a model which employs a graph to describe which cells are in contact, and examine its spatio-temporal dynamics. We first give an instability condition for the homogeneous steady-state.

Lithography for patterning trench contacts
Microelectronic Engineering, 1992Abstract Lithography processes suitable for the patterning of buried trench contacts were tested for two different stacked capacitor cell concepts and evaluated with respect to process latitudes.

Transcultural Patterns of Ritualized Contact Behavior
1971Man communicates with his fellow man, with speech but also with a number of expression-movements. Whether these signals belong to an innate repertoire of motor patterns which are not learned is a point of controversy. Gehlen is of the opinion that, except perhaps for a few reflexes of the newborn, there are no innate behavior patterns in man [14].
