Critical theory emerged in Germany in the 1920s with the establishment of the Institute for Social Research at Frankfurt-am Main in 1923. The term ‘critical theory’ was originally coined and used by Max Horkheimer in 1937 to describe the theoretical programme of the school. Known as the ‘Frankfurt School’ the group became exiled to France then to the United States in the early 1930s until 1941 ...

The state of the science of information security is astonishingly rich with solutions and tools to incrementally and selectively solve the hard problems. In contrast, the state of the actual application of science, and the general knowledge and understanding of the existing science, is lamentably poor. Still we face a dramatically growing dependence on information technology, e.g., the Internet...

We introduce a new method to measure the lateral diffusivity of a surfactant monolayer at the fluid-fluid interface, called fluorescence recovery after merging (FRAM). FRAM adopts the same principles as the fluorescence recovery after photobleaching (FRAP) technique, especially for measuring fluorescence recovery after bleaching a specific area, but FRAM uses a drop coalescence instead of photo...

Jean Leray (November 7, 1906–November 10, 1998) was confined to an officers’ prison camp (“Oflag”) in Austria for the whole of World War II. There he took up algebraic topology, and the result was a spectacular flowering of highly original ideas, ideas which have, through the usual metamorphism of history, shaped the course of mathematics in the sixty years since then. Today we would divide his...

UNLABELLED Tropical is a software for simulation and parameter estimation of reaction-diffusion models. Based on spatio-temporal microscopy images, Tropical estimates reaction and diffusion coefficients for user-defined models. Tropical allows the investigation of systems with an inhomogeneous distribution of molecules, making it well suited for quantitative analyses of microscopy experiments s...

We created a simulation model to investigate the characteristics of fluorescence in two-photon-excited samples. In the model, the sample is a diffusible solution of fluorophore molecules, which is divided into cubic cells and illuminated by a train of focused laser pulses described as a Gaussian beam. Simulating the state transitions according to a multilevel photodynamic model (also including ...

Objective To evaluate intraocular scattering in eyes with posterior capsule opacification by means of an objective scatter index (OSI) obtained from double-pass images of optical quality assessment system (OQAS TM II) and to determine the indication for laser capsulotomy when patients report visual disturbances without decreased visual acuity. Methods In this prospective, observational, and n...

The poverty rate among children is higher today than it was in the late 1960s, a few years after the War on Poverty was launched. In 1969, 13.8 percent of all children lived in families with incomes below the poverty line; in 1988, 19.7 percent did. Whereas most studies of child poverty focus on the negative effects of deteriorating economic circumstances and the increasing percentage of childr...

This paper describes associations among delivery-location, training of birth attendants, birthing practices, and early postpartum morbidity in women in slum areas of Dhaka, Bangladesh. During November 1993-May 1995, data on delivery-location, training of birth attendants, birthing practices, delivery-related complications, and postpartum morbidity were collected through interviews with 1,506 wo...

The in-medium sum rules are employed to calculate the shifts in the mass and residue as well as the scalar and vector self-energies of the heavy [Formula: see text] and [Formula: see text] baryons, with Q being b or c quark. The maximum shift in mass due to nuclear matter belongs to the [Formula: see text] baryon and it is found to be [Formula: see text]. In the case of residue, it is obtained ...
