Demonstration of a two-dimensional divertor Thomson scattering system on DIII-D.

Recent upgrades providing two-dimensional divertor Thomson scattering (DTS-2D) measurements of Te and ne during a DIII-D plasma shot and a thorough description of system components and their functionality are presented. This system expands the capabilities of the existing single divertor Floor measurement location by introducing seven additional laser beam path options in the poloidal plane, spanning major radii from 1.062 to 1.

In-Person and Virtual World Mindfulness Training: Trust, Satisfaction, and Learning.

Virtual worlds (VWs) present a viable, low-cost delivery mechanism for telehealth services. Although preliminary reports support the effectiveness of VWs in terms of health metrics, few studies have examined the perceived benefits and learning potential for military service members and veterans. Trust is integral to any interaction and may be even more important, and problematic to establish, during virtual interactions than in-person (IP) communications.

Characteristics and Impact of U.S. Military Blast-Related Mild Traumatic Brain Injury: A Systematic Review.

As a result of armed conflict, head trauma from exposure to blasts is an increasing critical health issue, particularly among military service members. Whilst numerous studies examined the burden of blast-related brain injuries on service members', few systematic reviews have been published. This work provides a comprehensive summary of the evidence on blast-related mild traumatic brain injury (mTBI) burden in active U.

The Effect of Traumatic Brain Injury (TBI) on Cognitive Performance in a Sample of Active Duty U.S. Military Service Members.

Introduction: Traumatic brain injury (TBI) is considered a signature injury from the fighting in Iraq and Afghanistan. Since the year 2000, over 370,000 U.S.

Self-Reported Sleep, Anxiety, and Cognitive Performance in a Sample of U.S. Military Active Duty and Veterans.

Unhealthy sleep can interfere with U.S. military service members affective and cognitive functioning, and increase accident and injury risks.

Speed-dependent Voigt lineshape parameter database from dual frequency comb measurements at temperatures up to 1305 K. Part II: Argon-broadened HO absorption, 6801-7188 cm.

We report argon-broadened water vapor transition parameters and their temperature dependence based on measured spectra spanning 6801-7188 cm from a broad-bandwidth, high-resolution dual frequency comb spectrometer. The 25 collected spectra of 2% water vapor in argon ranged from 296 K to 1305 K with total pressure spanning 100 Torr to 600 Torr. A multispectrum fitting routine was used in conjunction with a quadratic speed-dependent Voigt profile to extract broadening and shift parameters, and a power-law temperature-dependence exponent for both.

Speed-dependent Voigt lineshape parameter database from dual frequency comb measurements up to 1305 K. Part I: Pure HO absorption, 6801-7188 cm.

We measure speed-dependent Voigt lineshape parameters with temperature-dependence exponents for several hundred spectroscopic features of pure water spanning 6801-7188 cm. The parameters are extracted from broad bandwidth, high-resolution dual frequency comb absorption spectra with multispectrum fitting techniques. The data encompass 25 spectra ranging from 296 K to 1305 K and 1 to 17 Torr of pure water vapor.

Impact of In-Person and Virtual World Mindfulness Training on Symptoms of Post-Traumatic Stress Disorder and Attention Deficit and Hyperactivity Disorder.

Mindfulness meditation training has been shown to reduce stress and improve short-term memory for military personnel. However, no studies have investigated the effects of in-person and virtual world (VW) mindfulness training on Post-Traumatic Stress Disorder (PTSD) or Attention Deficit Hyperactivity Disorder (ADHD) symptoms. In this study, U.

Broadband, high-resolution investigation of advanced absorption line shapes at high temperature.

Spectroscopic studies of planetary atmospheres and high-temperature processes (e.g., combustion) require absorption line-shape models that are accurate over extended temperature ranges.

The effects of age on processing and storage in working memory span tasks and reading comprehension.

Unlabelled: BACKGROUND/STUDY CONTEXT: Declines in verbal working memory span task performance have been associated with deficits in the language processing abilities of healthy older adults, but it is unclear how storage and processing contribute to this relationship. Moreover, recent studies of the psychometric properties of span measures in the general cognitive literature highlight the need for a critical reassessment of age-related differences in working memory task performance.

Methods: Forty-two young (Mage = 19.

The influence of story context on a working memory span task.

The purpose of the present study was to examine factors that could influence whether recall performance in the reading span task (Daneman & Carpenter, 1980 ) would benefit from the contextual information from the sentences in the processing component of the task. More specifically, we investigated whether people would benefit from sentence sets that formed short stories or when the entire span task was one continuous story. Overall, there was a clear benefit for contextually related sentence sets (i.

Relationship between perceived stigma and depression severity.

The purpose of this study was to explore the relationship between perceived stigma and being in treatment for depression and current depression severity. Face-to-face interviews were conducted with a convenience sample of depressed subjects from a Veterans Administration outpatient mental health clinic (N = 54) and never-depressed subjects from a Veterans Administration primary care clinic (N = 50). Depression severity was measured using the 9-item Primary Care Evaluation of Mental Disorders depression measure.
