This article offers reflections on the development of the Rubin causal model (RCM), which were stimulated by the impressive discussions of the RCM and Campbell's superb contributions to the practical problems of drawing causal inferences written by Will Shadish (2010) and Steve West and Felix Thoemmes (2010). It is not a rejoinder in any real sense but more of a sequence of clarifications of pa...

A practical synthesis of a novel oxabicyclo[6.2.1]undecenetriol useful as a medicinal chemistry scaffold has been developed starting from l-ribose. The sequence involves an oxidation/Grignard addition sequence and a challenging ring-closing metathesis (RCM) reaction as the ring forming step. Exploration of the RCM substrate protecting groups revealed the key factor for successful nine-membered ...

This thesis presents the Random-Cluster Model (RCM), a novel geometry-based stochastic model for frequency-selective and smoothly time-variant MIMO radio channels. The RCM uses the concept of clusters, i.e. groups of multipath components (MPCs), to model the propagation environment. In the RCM, the environment is solely specified by the multivariate distribution of the cluster parameters, such ...

Dear Editor, Lentigo maligna (LM) is a form of melanoma in situ that occurs on sun exposed skin, particularly the head and neck areas, of elderly patients.1 A clinical diagnosis of LM at an early stage is often diffi cult, even for experienced dermatologists as benign lesions such as solar lentigo and seborrheic keratosis may have similar clinical features. Dermoscopy has been shown to be a val...

8 [1] The objective of this work is a realistic Rice Convection Model (RCM) simulation of 9 a modest substorm that occurred on 22 July 1998 and was observed by the Geotail 10 spacecraft in the inner plasma sheet. It represents the first time the RCM has been used for 11 detailed modeling of an inner magnetospheric event using data from a spacecraft in the 12 inner plasma sheet beyond geosynchro...

In a deregulated power industry, a maintenance strategy is of critical importance for transmission systems composed of aging components. Such a strategy can provide significant cost savings by optimizing maintenance decisions for power system operation. This paper presents a Reliability-Centered Maintenance (RCM) model for developing a maintenance strategy in a transmission system. This model i...

SUMMARY Reflectance confocal microscopy (RCM) is a new non-invasive imaging technique that enables visualizing cells and structures in living skin in real-time with resolution close to that of histological analysis. RCM has been successfully implemented in the assessment of benign and malignant lesions. Most importantly, it also enables monitoring dynamic changes in the skin over time and in re...

Two ruthenium olefin metathesis initiators featuring electronically modified quinoline-based chelating carbene ligands are introduced. Their reactivity in RCM and ROMP reactions was tested and the results were compared to those obtained with the parent unsubstituted compound. The studied complexes are very stable at high temperatures up to 140 °C. The placement of an electron-withdrawing functi...
