Elliptic flow: Transition from out-of-plane to in-plane emission in Au + Au collisions

Abstract: We have measured the proton elliptic flow excitation function for the Au + Au system spanning the beam energy range 2 -- 8 AGeV. The excitation function shows a transition from negative to positive elliptic flow at a beam energy, $E_{tr} \sim$ 4 AGeV. Detailed comparisons with calculations from a relativistic Boltzmann-equation are presented. The comparisons suggest a softening of the nuclear equation of state (EOS) from a stiff form (K \sim 380 MeV) at low beam energies (E_{Beam} \le 2 AGeV) to a softer form (K \sim 210 MeV) at higher energies (E_{Beam} \ge $ 4 AGeV) where the calculated baryon density $ \rho \sim 4 \rho_0$.

Molecular and cellular reorganization of neural circuits in the human lineage

Abstract: To better understand the molecular and cellular differences in brain organization between human and nonhuman primates, we performed transcriptome sequencing of 16 regions of adult human, chimpanzee, and macaque brains. Integration with human single-cell transcriptomic data revealed global, regional, and cell-type–specific species expression differences in genes representing distinct functional categories. We validated and further characterized the human specificity of genes enriched in distinct cell types through histological and functional analyses, including rare subpallial-derived interneurons expressing dopamine biosynthesis genes enriched in the human striatum and absent in the nonhuman African ape neocortex. Our integrated analysis of the generated data revealed diverse molecular and cellular features of the phylogenetic reorganization of the human brain across multiple levels, with relevance for brain function and disease.

Mother – child attachment in later middle childhood: Assessment approaches and associations with mood and emotion regulation

Abstract: This study examined the overlap and validity of several measures of mother – child attachment developed for preadolescents. Validity was assessed in part by examining how attachment is related to children's mood and emotion regulation. Mother – child attachment was assessed in a sample of 9 to 11 year-old children using a story stem interview technique and questionnaires. Positive and negative mood were scored from daily logs completed by children. Emotion regulation was assessed with mothers' reports of constructive coping and teacher reports of children's ability to tolerate frustration. Interview and questionnaire measures of attachment were not consistently related to one another, although both were related to mood and emotion regulation. As expected, secure attachment and maternal secure base support were related to higher levels of positive mood, more constructive coping, and better regulation of emotion in the classroom, with effects stronger for emotion regulation than for mood.

Detecting fake-good and fake-bad MMPI-2 profiles.

Abstract: This study examined the extent to which the validity scales of the Minnesota Multiphasic Personality Inventory-2 (MMPI-2) could identify subjects who were faking bad or faking good and differentiate between psychiatric patients and normal subjects who were faking bad. Subjects were 106 undergraduate college students and 50 psychiatric patients. Results indicate that the mean profiles and optimal cutoff scores resembled those previously reported for the original MMPI. Accurate identification of persons who were faking bad or faking good was achieved. It was possible to differentiate between the psychiatric patients and normal persons who were faking bad, but different cutoff scores were needed to differentiate between normals taking the test under standard instructions and those instructed to fake bad. Optimal cutoff scores were suggested.
