TL;DR: In this article, the authors studied the compactness of hot fusion reactions on various actinides and showed that the reactions leading to $Z\ensuremath{\theta}l{90}^{\ifmmode^\circ\else\textdegree\fi{}}$ (notequatorial compact or nec) are compact at the direction of the minor axis of the deformed reaction partner.
Abstract: Based on fragmentation theory extended to include the orientation degrees of freedom and higher multipole deformations up to hexadecapole deformations, the compactness of $^{48}\mathrm{Ca}$ induced reactions on various actinides is studied for Ds ($Z=110$) to 118 nuclei. It is shown that the reactions leading to $Z\ensuremath{\ge}114$ nuclei are ``compact'' hot fusion reactions at $\ensuremath{\theta}={90}^{\ifmmode^\circ\else\textdegree\fi{}}$ orientation angles (equatorial compact or ec; collisions that are in the direction of the minor axis of the deformed reaction partner), but the ones for $Zl114$ nuclei are compact at $\ensuremath{\theta}l{90}^{\ifmmode^\circ\else\textdegree\fi{}}$ (not-equatorial compact or nec). The phenomenon of ``barrier distribution in orientation degrees of freedom'' is observed for the first time to be related to the magnitudes of both the quadrupole and hexadecapole deformations of the deformed reaction partner. The ec configurations are obtained for the cases of quadrupole deformation alone and with small (including negative values) hexadecapole deformations. The presence of large (positive) hexadecapole deformations result in the nec configurations. These results are found to be quite general, applicable also to other lighter targets such as W and Ra with the $^{48}\mathrm{Ca}$ beam and to Pb based reactions. Furthermore, for compact hot fusion reactions, in addition to the $^{48}\mathrm{Ca}$ reaction valley, a number of other new reaction valleys (target-projectile combinations) are obtained, the most important one (next to $^{48}\mathrm{Ca}$) being the $^{54}\mathrm{Ti}$ nucleus used previously in Pb based cold fusion reaction studies but now proposed with deformed actinide nuclei such as $^{226}\mathrm{Ra}$, $^{232}\mathrm{Th}$, $^{238}\mathrm{U}$, and $^{242}\mathrm{Pu}$.

TL;DR: In this paper, the authors analyzed the directed flow of protons and pions in high-energy heavy-ion collisions in the incident energy range from 7.7$ to 27 GeV within a microscopic transport model.
Abstract: We analyze the directed flow of protons and pions in high-energy heavy-ion collisions in the incident energy range from $\sqrt{{s}_{NN}}=7.7$ to 27 GeV within a microscopic transport model. Standard hadronic transport approaches do not describe the collapse of directed flow below $\sqrt{{s}_{NN}}\ensuremath{\simeq}20$ GeV. By contrast, a model that simulates effects of a softening of the equation of state descibes well the behavior of directed flow data recently obtained by the STAR Collaboration [Phys. Rev. Lett. 112, 162301 (2014)]. We give a detailed analysis of how directed flow is generated. Particularly, we found that softening of the effective equation of state at the overlapping region of two nuclei, i.e., the reaction stages where the system reaches high baryon density state, is needed to explain the observed collapse of proton directed flow within a hadronic transport approach.

TL;DR: In this paper, the predictions of the thermal model for hadron production in comparison to latest data from RHIC and extrapolate the calculations to LHC energy were reviewed and compared with the recently released data from ALICE at the LHC.

TL;DR: It is proposed that individuals are aggregates that preserve a measure of temporal integrity, i.e., “propagate” information from their past into their futures, which allows for the identification of individuals at all levels of organization and provides a basis for testing assumptions about the natural scales of a system.
