Quiz : A middle aged lady with annular athrophic papules and plaques on her back: What is your diagnosis?

A 51 year old woman was referred to dermatology clinic with multiple asymptomatic erythematus papules and plaques on her back, which she had developed over the previous 2 months ago. In the dermatological examination, there were multiple atrophic papules with hypopigmented centers and sharp borders on her back, some of which were annular with elevated violaceous borders (Figures 1, 2). Fu...

Screen-printed back-to-back electroanalytical sensors: heavy metal ion sensing.

Screen-printed back-to-back microband electroanalytical sensors are applied to the quantification of lead(II) ions for the first time. In this configuration the electrodes are positioned back-to-back with a common electrical connection to the two working electrodes with the counter and reference electrodes for each connected in the same manner as a normal "traditional" screen-printed sensor. Pr...

Diffusion or bounce back in relativistic heavy-ion collisions?

The time evolution of pseudorapidity distributions of produced charged hadrons in d+Au collisions at √ sNN = 200 GeV is investigated. Results of a nonequilibrium-statistical Relativistic Diffusion Model with three sources are compared with a macroscopic ”bounce back” model that does not allow for statistical equilibration at large times, but instead leads to motion reversal. When compared to th...

Her Voice Lingers on and Her Memory Is Strategic: Effects of Gender on Directed Forgetting

The literature on directed forgetting has employed exclusively visual words. Thus, the potentially interesting aspects of a spoken utterance, which include not only vocal cues (e.g., prosody) but also the speaker and the listener, have been neglected. This study demonstrates that prosody alone does not influence directed-forgetting effects, while the sex of the speaker and the listener signific...
