Born's quest for the elusive divergence problem-free quantum theory of elec-tromagnetism led to the important discovery of the nonlinear Maxwell–Born– Infeld equations for the classical electromagnetic fields, the sources of which are classical point charges in motion. The law of motion for these point charges has however been missing, because the Lorentz(More)
Eighty years after de Broglie's, and a little more than half a century after Bohm's seminal papers, the de Broglie–Bohm theory (a.k.a. Bohmian mechanics), which is presumably the simplest theory which explains the orthodox quantum mechanics formalism, has reached an exemplary state of conceptual clarity and mathematical integrity. No other theory of quantum(More)
For classical Hamiltonian N-body systems with mildly regular pair interaction potential (in particular, L 2 loc integrability is required) it is shown that when N → ∞ in a fixed bounded domain Λ ⊂ R 3 , with energy E scaling as E ∝ N 2 , then Boltzmann's ergodic ensemble en-tropy S Λ (N, E) has the asymptotic expansion S Λ (N, N 2 ε) = −N ln N + s Λ (ε)N +(More)
In 1969 Ruelle published his construction of the thermodynamic limit, in the sense of Fisher, for the quasi-microcanonical entropy density of classical Hamiltonian N-body systems with stable and tempered pair interactions. Here, " quasi-microcanonical " refers to the fact that he discussed the entropy defined with a regularized microcanonical measure as(More)
State of the art animal and cell culture models fail to predict the ability of drugs to cross the blood-brain barrier as they lack comparability to the complex human situation. The development of novel pharmaceutics therefore requires in vitro models with human like cell response. Therefore, we are developing a model which mimics the organ environment(More)
The pair-specific ground state energy ε g (N) := E g (N)/(N (N − 1)) of Newtonian N body systems grows monotonically in N. This furnishes a whole family of simple new tests for minimality of putative ground state energies E x g (N) obtained through computer experiments. Inspection of several publicly available lists of such computer-experimentally
We discuss a class of quantum Abraham models in which the N-particle spinor wave function of N electrons solves a Pauli respectively Schrödinger equation, featuring regularized classical electromagnetic potentials which solve the semi-relativistic Maxwell-Lorentz equations for regularized point charges, which move according to some de Broglie-Bohm law of(More)
M&amp;ouml;ssenb&amp;ouml;ck proposes the <i>argument block</i> as a language construct for using statement sequences as arguments for procedures [M&amp;ouml;s92]. Such a construct enables users to define their own control structures. M&amp;ouml;ssenb&amp;ouml;ck is inspired by S<sc>MALLTALK</sc>-80 [GR83] and claims that most languages lack support of(More)
The case of a female patient showing aggressive, compulsive, destructive behaviour, ritualistic faecal smearing, and hyperactivity is presented. The behaviour is long standing, therapy-resistant, and its aetiology is unknown, although it is seemingly associated with chromosomal abnormalities secondary to abnormal plasma factors.
