Based on I(V) measurements for other adsorbates on NaCl films, we estimate that tunneling through the NIR state increases the tunneling current by about two orders of magnitude. The extrapolation of I to z ..."

Dramatic increase in vancomycin-resistant enterococci in Germany
"... Objectives: Among European countries, Germany has one of the highest proportions of vancomycin-resistant Enterococcus faecium bloodstream infections. The aim of this study was to investigate the development of vancomycin-resistant enterococci (VRE) in German hospitals and to consider the regional di ..."

departments for 2 year periods from 2007 to 2012 were analysed. The proportion of VRE increased significantly for surgical site infections (526%; P,0.01) and blood-stream infections (265%; P,0.01) and non-significantly for urinary tract infections (278%; P0.07). A large sub-group of ICUs also reported VRE
Dramatic Increase in Fatigue Life in Hierarchical Graphene Composites
"... ABSTRACT: We report the synthesis and fatigue characterization of fiberglass/epoxy composites with various weight fractions of graphene platelets infiltrated into the epoxy resin as well as directly spray-coated on to the glass micro-fibers. Remarkably only ~0.2 % (with respect to the epoxy resin we ..."

weight and ~0.02 % with respect to the entire laminate weight) of graphene additives enhanced the fatigue life of the composite in the flexural bending mode by up to 1200-fold. By contrast, under uniaxial tensile fatigue conditions, the graphene fillers resulted in ~3 to 5-fold increase in fatigue life
Mobility increases the capacity of ad-hoc wireless networks
- IEEE/ACM TRANSACTIONS ON NETWORKING
, 2002
"... The capacity of ad-hoc wireless networks is constrained by the mutual interference of concurrent transmissions between nodes. We study a model of an ad-hoc network where n nodes communicate in random source-destination pairs. These nodes are assumed to be mobile. We examine the per-session throughpu ..."

-session throughput for applications with loose delay constraints, such that the topology changes over the time-scale of packet delivery. Under this assumption, the per-user throughput can increase dramatically when nodes are mobile rather than fixed. This improvement can be achieved by exploiting node mobility as a
An ecological perspective on health promotion programs
- Health Education Quarterly
, 1988
"... During the past 20 years there has been a dramatic increase in societal interest in preventing disability and death in the United States by changing individual behaviors linked to the risk of contracting chronic diseases. This renewed interest in health pro-motion and disease prevention has not been ..."

Constrained K-means Clustering with Background Knowledge
- In ICML
, 2001
"... Clustering is traditionally viewed as an unsupervised method for data analysis. However, in some cases information about the problem domain is available in addition to the data instances themselves. In this paper, we demonstrate how the popular k-means clustering algorithm can be pro tably modi- ed ..."

Review Of The Satisfaction With Life Scale
, 2009
"... The Satisfaction With Life Scale (SWLS) was developed to assess satis-faction with the respondent’s life as a whole. The scale does not assess satisfaction with life domains such as health or finances but allows subjects to integrate and weight these domains in whatever way they choose. Normative d ..."

it assesses an individuals’ conscious evaluative judgment of his or her life by using the person’s own criteria. The last decade has seen a dramatic increase in research on the construct of sub-jective well-being (SWB; Diener, 1984; Diener & Larsen, 1993). This research has
A Rate-Adaptive MAC Protocol for Multi-Hop Wireless Networks
, 2001
"... Wireless local area networks (W-LANs) have become increasingly popular due to the recent availability of affordable devices that are capable of communicating at high data rates. These high rates are possible, in part, through new modulation schemes that are optimized for the channel conditions bring ..."

bringing about a dramatic increase in bandwidth efficiency. Since the choice of which modulation scheme to use depends on the current state of the transmission channel, newer wireless devices often support multiple modulation schemes, and hence multiple data rates, with mechanisms to switch between them
