Here, we present the design of a new reactor-like high-temperature near ambient pressure scanning tunneling microscope (HT-NAP-STM) for catalysis studies. This HT-NAP-STM was designed for exploration of structures of catalyst surfaces at atomic scale during catalysis or under reaction conditions. In this HT-NAP-STM, the minimized reactor with a volume of reactant gases of ∼10 ml is thermally is...

Although many neuroimaging studies have considered verbal and visual short-term memory (STM) as relying on neurally segregated short-term buffer systems, the present study explored the existence of shared neural correlates supporting verbal and visual STM. We hypothesized that networks involved in attentional and executive processes, as well as networks involved in serial order processing, unde...

Elevated soluble thrombomodulin (sTM) levels are an accepted marker of endothelial damage. The physiological significance of plasma endothelial protein C receptor (sEPCR) levels is not known. To assess the relevance of this plasma protein in Wegener's granulomatosis (WG), sEPCR levels were measured in sera obtained from WG patients and related to disease activity, sTM levels, and other known ma...

OBJECTIVE Evaluate the resource-constrained, evidence-based, and outcome-driven Sacco Triage method (STM) for military-age victims of blunt, penetrating, and blast overpressure-like trauma. METHODS STM is based on a mathematical model of resource-constrained triage. Its objective is to maximize expected survivors given constraints on transport and treatment resources. STM uses estimates of ti...

This vignette demonstrates how to use the Structural Topic Model, stm, R package. The Structural Topic Model (STM) allows researchers to estimate a topic model which includes document-level meta-data. The stm package provides a range of features from model selection to extensive plotting and visualization options.

We present the design and performance of a cryogenic scanning tunneling microscope (STM) which operates inside a water-cooled Bitter magnet, which can attain a magnetic field of up to 38 T. Due to the high vibration environment generated by the magnet cooling water, a uniquely designed STM and a vibration damping system are required. The STM scan head is designed to be as compact and rigid as p...

Transactional memory dramatically reduces the complexity of writing concurrent code. Yet, seamless integration of transactional constructs in application code typically comes with a significant performance penalty. Recent studies have shown that compiler support allows producing highly efficient STM-based applications without putting the hassle on the programmer. So far, STM integration has bee...

We present a simple one-dimensional model to find design criteria for a scanning tunneling microscope (STM) minimizing the response of the tip-sample distance to external mechanical disturbances. The underlying concept-achieving a response that is in phase and same amplitude-goes beyond the conventional approach to construct the STM as stiff as possible. It introduces optimization conditions re...

Depth-from-Defocus (DFD) using the Spatial-Domain Convolution/Deconvolution Transform Method (STM) is a useful technique for 3D vision. STM involves simple local operations in the spatial domain on only two images recorded with diierent camera parameters (e.g. by changing lens position or changing aperture diameter). In this paper we provide a theoretical treatment of the noise sensitivity anal...

BACKGROUND AND PURPOSE Increased soluble thrombomodulin (sTM) concentration has been associated with recurrent coronary events, whereas in one prospective study it predicted fewer first-ever coronary events. One study found no relationship between brain infarction (BI) and sTM levels. Among all subjects of the Etude du Profil Génétique de l'Infarctus Cérébral (GENIC) cohort and those free of pr...
