Quarkonium Suppression
I discuss quarkonium suppression in equilibriated strongly interacting
matter. After a brief review of basic features of quarkonium production I
discuss the application of recent lattice data on the heavy quark potential to
the problem of quarkonium dissociation as well as the problem of direct lattice
determination of quarkonium properties in finite temperature lattice QCD.Comment: Invited plenary talk presented on 4th International Conference on

Suppressing Unwanted Autobiographical Memories Reduces Their Automatic Influences: Evidence from Electrophysiology and an Implicit Autobiographical Memory Test
The present study investigated the extent to which people can suppress unwanted autobiographical memories in a mock crime memory detection context. Participants encoded sensorimotor-rich memories by enacting a lab crime (stealing a ring) and received direct suppression instructions so as to evade guilt detection in a brainwave-based concealed information test. Aftereffects of suppression on automatic memory processes were measured in an autobiographical implicit association test (aIAT). Results showed that suppression attenuated brainwave activity (P300) that is associated with crime-relevant memory retrieval, rendering innocent and guilty/suppression participants indistinguishable. However, guilty/suppression and innocent participants could nevertheless be discriminated via the late posterior negative slow wave, which may reflect the need to monitor response conflict arising between voluntary suppression and automatic recognition processes. Lastly, extending recent findings that suppression can impair implicit memory processes; we provide novel evidence that suppression reduces automatic cognitive biases that are otherwise associated with actual autobiographical memories
Depth of interocular suppression associated with continuous flash suppression, flash suppression, and binocular rivalry
When conflicting images are presented to the corresponding regions of the two eyes, only one image may be consciously perceived. In binocular rivalry (BR), two images alternate in phenomenal visibility; even a salient image is eventually suppressed by an image of low saliency. Recently, N. Tsuchiya and C. Koch (2005) reported a technique called continuous flash suppression (CFS), extending the suppression duration more than 10-fold. Here, we investigated the depth of this prolonged form of interocular suppression as well as conventional BR and flash suppression (FS) using a probe detection task. Compared to monocular viewing condition, CFS elevated detection thresholds more than 20-fold, whereas BR did so by 3-fold. In subsequent experiments, we dissected CFS into several components. By manipulating the number and timing of flashes with respect to the probe, we found that the stronger suppression in CFS is not due to summation between BR and FS but is caused by the summation of the suppression due to multiple flashes. Our results support the view that CFS is not a stronger version of BR but is due to the accumulated suppressive effects of multiple flashes
Paradoxical effects of Worrisome Thoughts Suppression: the influence of depressive mood
Thought suppression increases the persistence of unwanted idiosyncratic worries
thoughts when individuals try to suppress them. The failure of suppression may
contribute to the development and maintenance of emotional disorders. Depressive
people seem particulary prone to engage in unsuccessful mental control strategies such
as thought suppression. Worry has been reported to be elevated in depressed individuals
and a dysphoric mood may also contribute for the failure of suppression. No studies
examine, however, the suppression of worisome thoughts in individuals with depressive
symptoms. To investigate the suppression effects of worrisome thoughts, 46
participants were selected according to the cut-off score of a depressive
symptomatology scale and they were divided in two groups (subclinical and nonclinical
group). All the individuals took part in an experimental paradigm of thought
suppression. The results of the mixed factorial analysis of variance revealed an
increased frequency of worrisome thoughts during the suppression phase on depending
of the depressive symptoms. These findings confirm that depressive mood can reduce
the success of suppression.info:eu-repo/semantics/publishedVersio
Emotional suppression and well-being in immigrants and majority group members in the Netherlands
We were interested in interethnic differences in emotional suppression. We propose a model in which suppression of specific emotional experiences (suppressive behaviours during interactions with others) mediates the relationship between emotional suppression tendency (intention to suppress emotions) and well-being, operationalised as mood disturbance, life dissatisfaction and depressive and physical symptoms. The sample consisted of 427 majority group members and 344 non-Western and 465 Western immigrants in the Netherlands. Non-Western immigrants scored higher on emotional suppression tendency and lower on well-being than the other groups. We did not find interethnic differences in suppression of specific emotional experiences. The full mediation model was supported in all groups. Interethnic differences in well-being could not be accounted for by differences in emotional suppression
The Right to Vote, The Right to Health: Voter Suppression as a Determinant of Racial Health Disparities
Civic participation is beneficial to oneâs health. Conversely, being unable to participate, such as being unable to vote, may be detrimental for health. Barriers that prevent voting and civic participation, which constitute voter suppression, disproportionately impact people of color. Therefore, voter suppression may explain intractable racial health disparities. However, few studies have examined the connection between voter suppression and health. In consideration of the frequent, and increasing, reports of voter suppression in recent elections, including the rise in voter identification laws, the reduction in early voting opportunities, and the closing of polling places, the field of public health should address voter suppression as a significant determinant of health inequities. This paper suggests a framework for how voter suppression may operate to negatively impact health and well-being, especially for people of color. Lastly, directions for future research are recommended to begin to disentangle the complex relationship between civic participation and health
Thermal Upsilon(1s) and chi_b1 suppression in sqrt(s_NN)=2.76 TeV Pb-Pb collisions at the LHC
I compute the thermal suppression of the Upsilon(1s) and chi_b1 states in
sqrt(s_NN)=2.76 TeV Pb-Pb collisions. Using the suppression of each of these
states I estimate the total R_AA for the Upsilon(1s) state as a function of
centrality, rapidity, and transverse momentum. I find less suppression of the
chi_b1 state than would be traditionally assumed; however, my final results for
the total Upsilon(1s) suppression are in good agreement with recent preliminary
CMS data.Comment: 4 pages, 4 figures; v4: published versio
