Electron cryomicroscopy can yield near-atomic resolution structures of highly ordered macromolecular complexes. Often however some subunits bind in a flexible manner, have different symmetry from the rest of the complex, or are present in sub-stoichiometric amounts, limiting the attainable resolution. Here we report a general method for the localized three-dimensional reconstruction of such sub...

Comparing the intensities of the well separated two-photon photoemission lines from image-potential states on clean and Ar covered Cu(1 0 0) surfaces we show that Ar atoms are desorbed by photons of only 4.43 eV energy. The crosssection of this desorption by electronic transition process is very low, only 1.3 barn (1.3 · 10 24 cm). Experimentally, it is accessible due to the high light intensit...

We consider a general discrete-time financial market with proportional transaction costs as in [Kabanov, Stricker and Rásonyi Finance and Stochastics 7 (2003) 403–411] and [Schachermayer Math. Finance 14 (2004) 19–48]. In addition to the usual investment in financial assets, we assume that the agents can invest part of their wealth in industrial projects that yield a nonlinear random return. We...

The goal of this study was to determine whether differences exist between young and elderly adults in cautiousness or tendency to approach imbalance during a forward reaching task. Young (n = 26) and elderly (n = 25) adults participated in trials that required them to reach forward as quickly as possible to contact a target that moved back and forth, in and out of reach. "Voluntary reach" was c...

Recent research on statistical multiplexing has provided many new insights into the achievable multiplexing gain in QoS networks, however, generally only in terms of the gain experienced at a single switch. Evaluating the statistical multiplexing gain in a general network remains a difficult challenge. In this paper we describe two distinct network designs for statistical end-to-end delay guara...

One of the main obstacles to including transient dynamic effects into the performance functions of a structural optimization is the high computational cost of each time-dependent simulation. The focus of this paper is on the application of model order reduction techniques to reduce the transient analysis time for the attainable optimization process. The software mor4ansys developed at IMTEK per...

Spitzer observations of exoplanets routinely yield photometric accuracies of better than one part in 10,000. However, the attainable precision is limited in part by pointing drifts, which have the effect of moving the target to less stable or lesswell characterized regions of Spitzer’’s IRAC detector arrays. Here we examine a large sample of observing sequences in an effort to identify the caus...

Fault identification capabilities are becoming increasingly important in modern designs, not only in support of design debugging methodologies, but also for the purpose of process characterization and yield enhancement. At the same time, hierarchical test approaches are becoming the prevalent means for addressing the size and complexity of large designs and for accommodating the varying individ...

Much effort has been devoted to the synthesis of gold nanoparticles with different shapes, including the zero-dimensional nanospheres, one dimensional nanorods, and two-dimensional nanoplates. Compared to zero or one dimensional nanostructures, the synthesis of two-dimensional nanostructures in high yield has always been more involved, often requiring complex and timeconsuming steps such as mor...
