Directly-excited 15N ssNMR spectroscopy at natural abundance is generally capable of providing information on N-doped carbon materials and therefore elucidating the catalytic activity atomic level.

Many senrice courses in statistics, in my experience, have degenerated into the presentation of a set of recipes. The prevailing situation extant in many courses was summed up recently by my son, himself a trainee engineer, when he said, "I lean the recipes to pass the exam but I don't really understand the material". In fact the rapidity with which the material in his course has been presented...

In this paper, we present a novel indexing data structure called RDHT (Range capable Distributed Hash Table) derived from skip lists and specifically designed for storing and retrieving geographic data from a structured P2P network overlay. We have developed RDHTs as backend for the DART search engine, whose goal is to efficiently answer complex queries based on semantics and geographical conte...

The traditional action-oriented surgical personality, although essential in the service of solving emergent operative dilemmas, may serve as a barrier to introspection. Certainly, challenges of the twenty-first century practice environment, including time constraints, also distract from self-reflection. Without engaging in moments of introspection, surgeons risk not only abandoning dying patien...

A survey is given on two decades of developments in the field, encompassing an increase in computing power by four orders of magnitude. The '4-D approach' integrating expectation-based methods from systems dynamics and control engineering with methods from AI has allowed to create vehicles with unprecedented capabilities in the technical realm: Autonomous road vehicle guidance in public traffic...

Current surgical robotic systems in orthopaedics lack realistic pre-operative simulations and utilize invasive methods to register bone intra-operatively. A multidisciplinary group of researchers is addressing these deeciencies in the context of robotic cementless hip replacement surgery. In this paper we outline our current research progress and a road-map for the short-term future of our rese...

We develop a formal model in which the government provides public goods in different policy fields for its citizens. We start from the basic premise that two office-motivated candidates have differential capabilities in different policy fields, and compete by proposing how to allocate government resources to those fields. The model has a unique equilibrium that differs substantially from the st...

Even sophisticated branch-prediction techniques necessarily suffer some mispredictions, and even relatively small mispredict rates hurt performance substantially in current-generation processors. This suggests the study of multipath execution, in which the processor simultaneously executes code from both the taken and not-taken outcomes of a branch. This paper describes HydraScalar, a simulator...
