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: 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: These findings show that trees prioritize the investment of assimilates below ground, probably to regain root functions after drought, and propose that root restoration plays a key role in ecosystem resilience to drought, in that the increased sink activity controls the recovery of carbon balances.
Abstract: Climate projections predict higher precipitation variability with more frequent dry extremes(1). CO2 assimilation of forests decreases during drought, either by stomatal closure(2) or by direct environmental control of sink tissue activities(3). Ultimately, drought effects on forests depend on the ability of forests to recover, but the mechanisms controlling ecosystem resilience are uncertain(4). Here, we have investigated the effects of drought and drought release on the carbon balances in beech trees by combining CO2 flux measurements, metabolomics and (13)CO2 pulse labelling. During drought, net photosynthesis (AN), soil respiration (RS) and the allocation of recent assimilates below ground were reduced. Carbohydrates accumulated in metabolically resting roots but not in leaves, indicating sink control of the tree carbon balance. After drought release, RS recovered faster than AN and CO2 fluxes exceeded those in continuously watered trees for months. This stimulation was related to greater assimilate allocation to and metabolization in the rhizosphere. These findings show that trees prioritize the investment of assimilates below ground, probably to regain root functions after drought. We propose that root restoration plays a key role in ecosystem resilience to drought, in that the increased sink activity controls the recovery of carbon balances.

TL;DR: In this paper, the authors used diffusion tensor imaging (DTI) to reconstruct the origin, growth pattern and termination of axonal pathways in the human brain between 8 and 34 postconceptual weeks (PCW).
Abstract: The development of cortical axonal pathways in the human brain begins during the transition between the embryonic and fetal period, happens in a series of sequential events, and leads to the establishment of major long trajectories by the neonatal period. We have correlated histochemical markers (acetylcholinesterase (AChE) histochemistry, antibody against synaptic protein SNAP-25 (SNAP-25-immunoreactivity) and neurofilament 200) with the diffusion tensor imaging (DTI) database in order to make a reconstruction of the origin, growth pattern and termination of the pathways in the period between 8 and 34 postconceptual weeks (PCW). Histological sections revealed that the initial outgrowth and formation of joined trajectories of subcortico-frontal pathways (external capsule, cerebral stalk–internal capsule) and limbic bundles (fornix, stria terminalis, amygdaloid radiation) occur by 10 PCW. As early as 11 PCW, major afferent fibers invade the corticostriatal junction. At 13–14 PCW, axonal pathways from the thalamus and basal forebrain approach the deep moiety of the cortical plate, causing the first lamination. The period between 15 and 18 PCW is dominated by elaboration of the periventricular crossroads, sagittal strata and spread of fibers in the subplate and marginal zone. Tracing of fibers in the subplate with DTI is unsuccessful due to the isotropy of this zone. Penetration of the cortical plate occurs after 24–26 PCW. In conclusion, frontal axonal pathways form the periventricular crossroads, sagittal strata and ‘waiting’ compartments during the path-finding and penetration of the cortical plate. Histochemistry is advantageous in the demonstration of a growth pattern, whereas DTI is unique for demonstrating axonal trajectories. The complexity of fibers is the biological substrate of selective vulnerability of the fetal white matter.
