TL;DR: In this paper, a detailed study of the centrality dependence of upsilon(2) over a broad transverse momentum range is presented, and a comparison of different analysis methods are made in order to estimate systematic uncertainties.
Abstract: We present STAR results on the elliptic flow upsilon(2) Of charged hadrons, strange and multistrange particles from,root s(NN) = 200 GeV Au+Au collisions at the BNL Relativistic Heavy Ion Collider (RHIC). The detailed study of the centrality dependence of upsilon(2) over a broad transverse momentum range is presented. Comparisons of different analysis methods are made in order to estimate systematic uncertainties. To discuss the nonflow effect, we have performed the first analysis Of upsilon(2) with the Lee-Yang zero method for K(S)(0) and A. In the relatively low PT region, P(T) <= 2 GeV/c, a scaling with m(T) - m is observed for identified hadrons in each centrality bin studied. However, we do not observe nu 2(p(T))) scaled by the participant eccentricity to be independent of centrality. At higher PT, 2 1 <= PT <= 6 GeV/c, V2 scales with quark number for all hadrons studied. For the multistrange hadron Omega, which does not suffer appreciable hadronic interactions, the values of upsilon(2) are consistent with both m(T) - m scaling at low p(T) and number-of-quark scaling at intermediate p(T). As a function ofcollision centrality, an increase of p(T)-integrated upsilon(2) scaled by the participant eccentricity has been observed, indicating a stronger collective flow in more central Au+Au collisions.

TL;DR: In this article, the authors tested attachment-based measures of parent-child relationships designed for the later middle-childhood years (9-12 years of age) and found modest associations across the different measures and moderate to high stability.
Abstract: Although a number of measures have been developed to assess parent-child attachments, validity data on middle-childhood measures are lacking. The present study tested attachment-based measures of parent-child relationships designed for the later middle-childhood years (9-12 years of age). Self-reports from children assessed perceptions of security and avoidant and preoccupied coping. Some children also completed a projective interview assessing attachment state of mind. Mothers and fathers reported their willingness to serve as an attachment figure and were rated for responsiveness. Data were collected from a cross-sectional sample of 3rd and 6th graders and their parents. A 2-year follow-up on the younger sample provided data on the stability of the measures. There were modest associations across the different measures and moderate to high stability. The attachment-based measures were also related to teacher ratings of children's school adaptation.

TL;DR: A red-emitting dicyanomethylenedihydrofuran push-pull fluorophore is reengineered so that it is dark until photoactivated with a short burst of low-intensity violet light, which provides a new class of bright photoactivatable fluorophores needed for super-resolution imaging schemes that require active control of single molecule emission.
Abstract: We have reengineered a red-emitting dicyanomethylenedihydrofuran push-pull fluorophore so that it is dark until photoactivated with a short burst of low-intensity violet light. Photoactivation of the dark fluorogen leads to conversion of an azide to an amine, which shifts the absorption to long wavelengths. After photoactivation, the fluorophore is bright and photostable enough to be imaged on the single-molecule level in living cells. This proof-of-principle demonstration provides a new class of bright photoactivatable fluorophores, as are needed for super-resolution imaging schemes that require active control of single molecule emission.

TL;DR: People who read a congruently framed message had greater flossing efficacy, intended to floss more, and used more dental flosses than did the participants who read an incongruent message.
Abstract: Health messages framed to be congruent with individuals' approach/avoidance motivations have been found to be more effective in promoting health behaviors than health messages incongruent with approach/avoidance motivations. This study examines the processes underlying this congruency effect. Participants (undergraduate students, N = 67) completed a measure of approach/avoidance orientation (the BIS/BAS scales) and read either a gain- or loss-framed message promoting dental flossing. Results demonstrated a congruency effect: Participants who read a congruently framed message had greater flossing efficacy, intended to floss more, and used more dental flosses than did the participants who read an incongruent message. Moreover, intention to perform the behavior predicted the congruency effect and self-efficacy mediated participants' intentions to perform the health behavior. Discussion centers on the role of personality factors and situational factors in models of behavior change.

TL;DR: In this article, the effectiveness and longevity of alum treatments were evaluated in 21 lakes (or lake basins) across the United States; 9 were polymictic and 12 were dimictic.
Abstract: Effectiveness and longevity of alum treatments were evaluated in 21 lakes (or lake basins) across the United States; 9 were polymictic and 12 were dimictic. Effectiveness was judged from reductions in lake TP (total phosphorus) and internal loading rate, as well as chlorophyll a (chl a), both initially and over periods ranging from 4 to 20 years following treatment. Internal loading rate was reduced in six of nine polymictic lakes/basins by an average of two-thirds, and lake TP was reduced by about one-half, which persisted for 5–11 years. Internal loading rate in dimictic lakes (7 of 7 with adequate data) remained reduced by an average of 80% for 4 to 21 years (average 13 yrs). For the six polymictic lakes, in which treatment was effective, chl a decreased by an average of two-thirds initially, but was about 40% less than die pre-treatment level after 5 to 11 years. Chl a decreased in seven dimictic lakes by an average of 57% initially and 42% after 5–18 years. In some cases, response was indepe...
