TL;DR: In this paper, the authors performed a systematic study of dijet production and suppression in nuclear collisions, providing new constraints on the mechanisms underlying partonic energy loss in dense matter, and showed that a narrow, back-to-back peak emerges above the decreasing background.
Abstract: The STAR Collaboration at the Relativistic Heavy Ion Collider reports measurements of azimuthal correlations of high transverse momentum (p(T)) charged hadrons in Au+Au collisions at higher p(T) than reported previously. As p(T) is increased, a narrow, back-to-back peak emerges above the decreasing background, providing a clear dijet signal for all collision centralities studied. Using these correlations, we perform a systematic study of dijet production and suppression in nuclear collisions, providing new constraints on the mechanisms underlying partonic energy loss in dense matter.

TL;DR: Current understanding on the interactions between inflammatory processes, EndMT, and endothelial dysfunction, with a focus on the mechanisms that regulate essential signaling pathways is reviewed, to provide novel therapeutic targets for the treatment of vascular diseases.
Abstract: Endothelial cells that line the inner walls of blood vessels are in direct contact with blood and display remarkable heterogeneity in their response to exogenous stimuli. These endothelial cells have unique location-dependent properties determined by the corresponding vascular beds and play an important role in regulating the homeostasis of the vascular system. Evidence suggests that vascular endothelial cells exposed to various environments undergo dynamic phenotypic switching, a key biological program in the context of endothelial heterogeneity, but that might result in endothelial cell dysfunction and, in turn, cause a variety of human diseases. Emerging studies show the importance of endothelial to mesenchymal transition (EndMT) in endothelial dysfunction during inflammation. EndMT is a complex biological process in which endothelial cells lose their endothelial characteristics, acquire mesenchymal phenotypes, and express mesenchymal cell markers such as alpha smooth muscle actin and fibroblast specific protein 1. EndMT is induced by inflammatory responses, leading to pathological states, including tissue fibrosis, pulmonary arterial hypertension, and atherosclerosis, via dysfunction of the vascular system. Although the mechanisms associated with inflammation-induced EndMT have been identified, unraveling the specific role of this phenotypic switching in vascular dysfunction remains a challenge. Here, we review the current understanding on the interactions between inflammatory processes, EndMT, and endothelial dysfunction, with a focus on the mechanisms that regulate essential signaling pathways. Identification of such mechanisms will guide future research and could provide novel therapeutic targets for the treatment of vascular diseases.

TL;DR: In this paper, measurements of two-particle correlations on angular difference variables η1 − η2 (pseudorapidity) and ηφ1 − φ2 (azimuth) are presented for all primary charged hadrons with transverse momentum 0.15 ≤ p_t ≤ 2 GeV/c======¯¯ and |η| ≤ 1.3 from Au-Au collisions at ∼ 130 GeV.
Abstract: Measurements of two-particle correlations on angular difference variables η1 − η2 (pseudorapidity) and
φ1 − φ2 (azimuth) are presented for all primary charged hadrons with transverse momentum 0.15 ≤ p_t ≤ 2 GeV/c
and |η| ≤ 1.3 from Au-Au collisions at
√s_(NN) = 130 GeV. Large-amplitude correlations are observed over a broad
range in relative angles where distinct structures appear on the same-side and away-side (i.e., relative azimuth less
than π/2 or greater than π/2). The principal correlation structures include that associated with elliptic flow plus a
strong, same-side peak. It is hypothesized that the latter results from correlated hadrons associated with semi-hard
parton scattering in the early stage of the heavy-ion collision which produces a jet-like correlation peak at small
relative angles. The width of the jet-like peak on η1 − η2 increases by a factor 2.3 from peripheral to central
collisions, suggesting strong coupling of semi-hard scattered partons to a longitudinally-expanding medium. The
new methods of jet analysis introduced here provide access to scattered partons at low transverse momentum well
below the kinematic range where perturbative quantum chromodynamics and standard fragmentation models are
applicable.

TL;DR: In this paper, the production of mesons containing strange quarks and both singly and doubly strange baryons were measured at central rapidity in pp collisions at the ALICE experiment at the LHC.
Abstract: The production of mesons containing strange quarks ($\Kzs$, $\phi$) and both singly and doubly strange baryons ($\rmLambda$, $\rmAlambda$, and $\Xis$) are measured at central rapidity in pp collisions at $\sqrt{s}$ = 0.9 $\tev$ with the ALICE experiment at the LHC. The results are obtained from the analysis of about 250 k minimum bias events recorded in 2009. Measurements of yields (dN/dy) and transverse momentum spectra at central rapidities for inelastic pp collisions are presented. For mesons, we report yields ($ $) of $0.184 \pm 0.002 \stat \pm 0.006 \syst$ for $\Kzs$ and $0.021 \pm 0.004 \stat \pm 0.003 \syst$ for $\phi$. For baryons, we find $ = 0.048 \pm 0.001 \stat \pm 0.004 \syst$ for $\rmLambda$, $0.047 \pm 0.002 \stat \pm 0.005 \syst$ for $\rmAlambda$ and $0.0101 \pm 0.0020 \stat \pm 0.0009 \syst$ for $\Xis$. The results are also compared with predictions for identified particle spectra from QCD-inspired models and provide a baseline for comparisons with both future pp measurements at higher energies and heavy-ion collisions.
