We present the first astronomical detection of the 14NH 3 (J, K) = (10, 6) line: nonthermal emission at several velocities in the Galactic star-forming region NGC7538. Using the Very Large Array we have imaged the (10,6) and (9,6) ammonia masers at several positions within NGC7538 IRS 1. The individual sources have angular sizes ≲ 0.1 arcsec corresponding to brightness temperatures TB ≳ 106 K. We apply the pumping model of Brown & Cragg, confirming the conjecture that multiple ortho-ammonia masers can occur with the same value of K. The positions and velocities of the (10,6) and (9,6) masers are modeled as motion in a possible disk or torus and are discussed in the context of recent models of the region. © 2012.

Social networking sites serve as both a source of information and a source of tension between romantic partners. Previous studies have investigated the use of Facebook for monitoring former and current romantic partners, but why certain individuals engage in this behavior has not been fully explained. College students (N=328) participated in an online survey that examined two potential explanatory variables for interpersonal electronic surveillance (IES) of romantic partners: attachment style and relational uncertainty. Attachment style predicted both uncertainty and IES, with preoccupieds and fearfuls reporting the highest levels. Uncertainty did not predict IES, however. Future directions for research on romantic relationships and online surveillance are explored. © 2014 Mary Ann Liebert, Inc.

In this study, tomographic particle image velocimetry (tomo-PIV) techniques are used to make volumetric measurements of the dust acoustic wave (DAW) in a weakly coupled dusty plasma system in an argon, dc glow discharge plasma. These tomo-PIV measurements provide the first instantaneous volumetric measurement of a naturally occurring propagating DAW. These measurements reveal over the measured volume that the measured wave mode propagates in all three spatial dimensional and exhibits the same spatial growth rate and wavelength in each spatial direction. © 2012 American Institute of Physics.

Social networking sites are becoming a prevalent form of communication in the escalation of romantic relationships. An online survey (n=403) addressed emerging adults' experiences with Facebook and romantic relationships, particularly a unique affordance of Facebook: The ability to declare oneself as "In a Relationship" and actively link one's profile to a romantic partner's, commonly known as going Facebook official. Results identified common social perceptions of the meaning of this status (regarding commitment, intensity, and social response) and both interpersonal and social motives for posting it on Facebook. Additionally, sex differences were identified in perceptions of meaning, wherein women felt this status conveyed commitment and intensity moreso than men did. Implications of this discrepancy on heterosexual relationship satisfaction and the prevailing role of technology in romantic relationships are discussed. © Mary Ann Liebert, Inc.

Over the past twelve years, two-dimensional and stereoscopic particle image velocimetry (PIV) techniques have been used to obtain detailed measurements of the thermal and transport properties of the microparticle component of dusty plasma systems. This letter reports on an extension of these techniques to obtain a volumetric, three-dimensional velocity vector measurement using tomographic PIV. Initial measurements using the tomographic PIV diagnostic are presented. © 2011 American Institute of Physics.
