T1  - Militär und Gesellschaft in der Frühen Neuzeit
N2  - Der Arbeitskreis Militär und Gesellschaft in der Frühen Neuzeit e. V. wurde im Frühjahr 1995 gegründet. Er hat es sich zur Aufgabe gemacht, die Erforschung des Militärs im Rahmen der frühneuzeitlichen Geschichte zu befördern und zugleich das Bewusstsein der Frühneuzeit-HistorikerInnen für die Bedeutung des Militärs in all seinen Funktionen zu wecken. Das Militär steht somit als soziale Gruppe selbst im Mittelpunkt der Aktivitäten des Arbeitskreises, wird aber auch in seinen Wirkungen und Repräsentationen thematisiert. Ziel ist es, die Rolle des Militärs als Teil der frühneuzeitlichen Gesellschaft umfassend herauszuarbeiten und zu würdigen. Insofern versteht der AMG seine Arbeit nicht nur als Beitrag zur Militärgeschichte, sondern vor allem als Beitrag zur Geschichte der Frühen Neuzeit insgesamt. Der Arbeitskreis bietet ein Diskussions- und Informationsforum durch die Organisation von Tagungen, die Herausgabe der Schriftenreihe ‚Herrschaft und soziale Systeme in der Frühen Neuzeit‘, die Zeitschrift ‚Militär und Gesellschaft in der Frühen Neuzeit‘ und die Mailingliste mil-fnz.

T1  - Design and evaluation of the computer-based training program Calcularis for enhancing numerical cognition
JF  - Frontiers in psychology
N2  - This article presents the design and a first pilot evaluation of the computer-based training program Calcularis for children with developmental dyscalculia (DD) or difficulties in learning mathematics. The program has been designed according to insights on the typical and atypical development of mathematical abilities. The learning process is supported through multimodal cues, which encode different properties of numbers. To offer optimal learning conditions, a user model completes the program and allows flexible adaptation to a child's individual learning and knowledge profile. Thirty-two children with difficulties in learning mathematics completed the 6-12-weeks computer training. The children played the game for 20 min per day for 5 days a week. The training effects were evaluated using neuropsychological tests. Generally, children benefited significantly from the training regarding number representation and arithmetic operations. Furthermore, children liked to play with the program and reported that the training improved their mathematical abilities.

T1  - All reversible dynamics in maximally nonlocal theories are trivial
N2  - A remarkable feature of quantum theory is nonlocality ( Bell inequality violations). However, quantum correlations are not maximally nonlocal, and it is natural to ask whether there are compelling reasons for rejecting theories in which stronger violations are possible. To shed light on this question, we consider post-quantum theories in which maximally nonlocal states ( nonlocal boxes) occur. We show that reversible transformations in such theories are trivial: they consist solely of local operations and permutations of systems. In particular, no correlations can be created; nonlocal boxes cannot be prepared from product states and classical computers can efficiently simulate all such processes.

T1  - Concentration of Measure for Quantum States with a Fixed Expectation Value
JF  - Communications in mathematical physics
N2  - Given some observable H on a finite-dimensional quantum system, we investigate the typical properties of random state vectors vertical bar psi >> that have a fixed expectation value < psi vertical bar H vertical bar psi > = E with respect to H. Under some conditions on the spectrum, we prove that this manifold of quantum states shows a concentration of measure phenomenon: any continuous function on this set is almost everywhere close to its mean. We also give a method to estimate the corresponding expectation values analytically, and we prove a formula for the typical reduced density matrix in the case that H is a sum of local observables. We discuss the implications of our results as new proof tools in quantum information theory and to study phenomena in quantum statistical mechanics. As a by-product, we derive a method to sample the resulting distribution numerically, which generalizes the well-known Gaussian method to draw random states from the sphere.
