CONTEXT New York City firefighters responding to the World Trade Center (WTC) disaster on September 11, 2001, were exposed to numerous hazards. A medical screening program was conducted 3 weeks after the disaster on a sample of firefighters. OBJECTIVES To determine whether arrival time at the WTC and other exposure variables (including respirator use) were associated with symptoms and changes...

OBJECTIVES We identified trends in the prevalence of elevated posttraumatic stress disorder (PTSD) risk as determined by the Fire Department of the City of New York (FDNY)-modified PTSD Checklist in World Trade Center (WTC)-exposed firefighters. We also examined trends in relation to WTC exposure, social support, change in recreational activities, and functional health. METHODS We analyzed 16...

Willingness to communicate (WTC) plays a central role in learning a second/foreign language. The present study was conducted to investigate the effect of doing problem-solving task on learners’ WTC in English. To fulfill the purpose of the study, 61 pre-intermediate learners were chosen by means of administrating a placement test. Learners were pretested through three scales of WTC and its two ...

Introduction Proton pump inhibitors (PPIs), a common treatment for gastroesophageal reflux disease (GERD), were recently associated with increased risk of dementia. However, severe or chronic stress including, for example, posttraumatic stress disorder (PTSD) was not accounted for. This study examined whether PPI use was associated with severe cognitive impairment (SCI) and whether PTSD explain...

In this work we study the secrecy capacity of Gaussian multiple-input multiple-output (MIMO) wiretap channels (WTCs) with a finite memory, subject to a per-symbol average power constraint on the MIMO channel input. MIMO channels with finite memory are very common in wireless communications as well as in wireline communications (e.g., in communications over power lines). To derive the secrecy ca...

Trajectories of disaster-related posttraumatic stress disorder (PTSD) symptoms are often heterogeneous, and associated with common and unique risk factors, yet little is known about potentially modifiable psychosocial characteristics associated with low-symptom and recovering trajectories in disaster responders. A total of 4487 rescue and recovery workers (1874 police and 2613 non-traditional r...

BACKGROUND Studies have consistently documented declines in respiratory health after 11 September 2001 (9/11) among surviving first responders and other World Trade Center (WTC) rescue, recovery, and clean-up workers. OBJECTIVES The goal of this study was to describe the risk of newly diagnosed asthma among WTC site workers and volunteers and to characterize its association with WTC site expo...

Walking technicolor (WTC) models predict the existence of heavy neutral pseudoGoldstone bosons (PGBs), whose masses are typically expected to be larger than 100 GeV. In this paper, we investigate the production and decay of these particles at the high energy ee experiments, LEP II and NLC. We find that, in WTC models, the production of neutral PGBs can be significantly enhanced, by one or two o...

OBJECTIVE To assess how the effect of World Trade Center (WTC) exposure on physician-diagnosed chronic rhinosinusitis (CRS) in firefighters changed during the decade following the attack on 9/11 (11 September 2001 to 10 September 2011). METHODS We examined temporal effects on the relation between WTC exposure and the incidence of physician diagnosed CRS in firefighters changed during the deca...
