The catastrophic destruction of the World Trade Center (WTC) on 11 September 2001 caused the release of high levels of airborne pollutants into the local environment. To assess the toxicity of fine particulate matter [particulate matter with a mass median aerodynamic diameter < 2.5 microm (PM2.5)], which may adversely affect the health of workers and residents in the area, we collected fallen d...

OBJECTIVES We hypothesise that there is an association between an elevated pulmonary artery/aorta (PA/A) and World Trade Center-Lung Injury (WTC-LI). We assessed if serum vascular disease biomarkers were predictive of an elevated PA/A. DESIGN Retrospective case-cohort analysis of thoracic CT scans of WTC-exposed firefighters who were symptomatic between 9/12/2001 and 3/10/2008. Quantification...

Willingness to communicate in a second language (L2 WTC) has recently become an important concept across disciplines of second language acquisition (SLA) and communication. It has been proposed that pedagogic goals should be to increase learners’ L2 WTC so as to facilitate language learning. Incorporating the Canadian social psychological approach to L2 learning, extant research has suggested t...

Willingness to Communicate (WTC) has become an important concept in second language (L2) classroom context. WTC is proven as a predictor of participation since students who tend have high participated more interaction and they are likely be ready get involved any interactions using their L2 both inside outside classroom. Given the central role teachers play pedagogy, shape curriculum within con...

OBJECTIVES To examine the long-term behavioral consequences of exposure to the World Trade Center (WTC) attacks in preschool children and to evaluate whether conjoined exposure to disaster and to other traumatic events has additive effects. DESIGN Retrospective cohort study. SETTING Lower Manhattan, New York. PARTICIPANTS A total of 116 preschool children directly exposed to the WTC attac...

BACKGROUND The World Trade Center (WTC) attacks exposed thousands of workers to hazardous environmental conditions and psychological trauma. In 2002, to assess the health of these workers, Congress directed the National Institute for Occupational Safety and Health to establish the WTC Medical Monitoring and Treatment Program. This program has established a large cohort of WTC rescue, recovery, ...

The September 11, 2001 attack on the World Trade Center (WTC) resulted in a massive plume of dust and smoke that blanketed lower Manhattan and part of the Hudson-Raritan Estuary (HRE). The NOAA National Status and Trends Mussel Watch Program has long-term monitoring sites in the area and thus had an opportunity to assess the effect of the WTC attack on PAH and PCB contamination of the surroundi...

Complex continuous wavelet coherence (WTC) can be used for non-stationary signals, such as electroencephalograms. Areas of the WTC with a coherence higher than the calculated optimal threshold were obtained, and the sum of their areas was used as a criterion to differentiate between groups of experienced insight-focused meditators, calm-focused meditators and a control group. This method demons...

In many information-theoretic channel coding problems, adding an input cost constraint to the operational setup amounts restricting optimization domain in capacity formula. This paper shows that, contrast common belief, such a simple modification does not hold for cost-constrained (CC) wiretap (WTC). The secrecy-capacity of discrete memoryless (DM) WTC without constraints is described by single...

This study investigated the receptive and productive vocabulary command of learners based on their willingness to communicate (WTC) and critical thinking skill. The study also aimed to compare gifted and non-gifted learners in terms of the above-mentioned variables. To this end, 112 gifted and non-gifted Iranian EFL learners were picked out and given four instruments (W...
