Scanning tunneling microscopy reveals that Si(112) reconstructs into quasiperiodic, nanometer-scale facets. Each sawtoothlike facet consists of a single unit cell wide reconstructed (111) terrace s7 3 7 or 5 3 5d opposed by a 60 to 110 Å wide (337) terrace. Nanofacets with a similar structure are also observed on Si(335), indicating that they are a general phenomenon for some range of vicinalit...

Objectives: To estimate the rates of symptomatic respiratory, gastrointestinal and urinary infections in patients hospitalized with acute heart failure to describe clinical characteristics these patients. Methodology: A cross sectional study was conducted a large tertiary care cardiology hospital due non-infective causes were invited participate. Trained research assistants collected data using...

Silver is a naturally occurring element. Similar to other metals, the ionized form of silver (Ag(+1)) has known antimicrobial properties. A number of wound dressings incorporating silver ion or silver compounds have recently been developed and marketed. In addition, the antimicrobial effects of silver are currently being promoted in consumer products such as clothing and household appliances. T...

As bloggers and mobile phone eye-witnesses increasingly supplement the ‘news,’ it is more important than ever to understand how professional journalists develop their expertise. In this paper, we examine an intermediate level reporting practicum course to explore the learning processes therein. Using a new method called Epistemic Network Analysis, we also explore emergent relationships within d...

We give a combinatorial proof that k l-k-1 l + t q q q q a polynomial in q with nonnegative coefficients for nonnegative integers a, b, k, lwith a>~b and l~>k. In particular, for a=b=n and l=k, this implies the q-log-concavity of the Gaussian binomial coefficients k , which was conjectured q by BUTLER (Proc.
