We develop new semiparametric methods for estimating treatment effects. We focus on a setting where the outcome distributions may be thick tailed, where treatment effects are small, where sample sizes are large and where assignment is completely rand

We congratulate the authors of Wang and Blei (2018) on a thought-provoking article on causal inference in settings with unobserved confounders. We expect that their ideas will lead to further devel...

Impulse responses can be estimated to analyze the effects of a shock to a variable over time. Typically, (vector) autoregressive models are estimated and the impulse responses implied by the coefficients calculated. In general, however, there is no k

Spatiotemporal pattern formation in the catalytic CO oxidation on Pt(1 1 0) is controlled by means of global delayed feedback applied through the gas phase. Using photoemission electron microscopy we have investigated the dynamical response of the sy

Different applications of aspheric optics and their related fabrication methods are firstly summarized and then discussed using Carl Zeiss examples. This is done in order to highlight the potential and challenges of fabricating aspheric optics. The n

We first briefly review the subject of spatiotemporal pattern formation on microdesigned composite catalysts. One of the most significant interaction mechanisms between different reacting domains (consisting of different metal catalysts such as Pt an

This paper focuses on subsurface oxygen and its influence on pattern formation during CO-oxidation on platinum surfaces. For the observation of spatiotemporal pattern formation during catalytic reactions the photoelectron emission microscope (PEEM) h

Experiments with catalytic oxidation of carbon monoxide on Pt(110) show that chemical turbulence in this system can be suppressed by application of appropriate global delayed feedback. Different spatiotemporal patterns, seen near the transition from
