Predictions for charged hadron, identified light hadron, quarkonium, photon, jet and gauge bosons in p+ Pb collisions at [Formula: see text] are compiled and compared. When test run data are available, they are compared to the model predictions.

ORIGINAL ARTICLEThe plant hormone auxin plays a critical role in regulating plant growth and development. Recent advances have been made in the understanding of auxin response pathways, primarily by the characterization of auxin response mutants in Arabidopsis. In addition, microRNAs (miRNAs) have been shown to be critical regulators of genes important for normal plant development and physiology. However, little is known about possible interactions between miRNAs and hormonal signaling during normal development. Here we show that an Arabidopsis microRNA, miR167, which has a complementary sequence to a portion of the AUXIN RESPONSE FACTOR6 (ARF6) and ARF8 mRNAs, can cause transcript degradation for ARF8, but not for ARF6. We report phenotypic characterizations of 35S::MIR167b transgenic lines, and show that severe 35S::MIR167b transgenic lines had phenotypes similar to those of an arf6 arf8 double mutant. The transgenic phenotypes suggest that miR167 may repress ARF6 at the level of translation. We demonstrate that the transgenic plants are defective in all four whorls of floral organs. In the transgenic flowers, filaments were abnormally short, anthers could not properly release pollen, and pollen grains did not germinate. Our results provide an important link between the miRNA-mediated regulatory pathway of gene expression and the auxin signaling network promoting plant reproductive development.Cell IntroductionThe plant hormone auxin plays a crucial role in developmental processes throughout the life cycle of a plant, including cell division and elongation, vascular tissue differentiation, root initiation, apical dominance, gravitropic and phototropic responses, fruit ripening, leaf senescence, and abscission of leaves and fruits [1]. How a simple chemical substance can affect such a wide variety of physiological processes has puzzled scientists in this field for many years. Recently, the identification of a gene family encoding proteins called auxin response factors (ARFs) in Arabidopsis [2, 3] provides a good entry to study auxin regulation at the molecular level. The ARF proteins can bind to the auxin-responsive cis elements in the promoter regions of members of an auxin-responsive gene family, GH3 [3]. The Arabidopsis genome encodes 23 known ARF proteins. Most ARF proteins contain an N-terminal domain for DNA-binding, a central region, and a C-terminal domain for protein-protein interaction [4]. ARF proteins can either activate or repress downstream genes, primarily depending on the amino acid sequence of their central region [5].Recently, miRNAs have been shown to play important roles in plant development and are widely believed to act as internal signals [6][7][8][9]. However, very little is known about the cross talk between miRNA signals and hormones. In Arabidopsis, a number of miRNAs were identified, showing critical roles in developmental regulations [7,[10][11][12][13][14][15][16][17][18][19][20].

We investigate the chaoticity parameter λ in two-pion interferometry in an expanding boson gas model. The degree of Bose-Einstein condensation of identical pions, density distributions, and Hanbury-Brown-Twiss (HBT) correlation functions are calculated for the expanding gas within the mean-field description with a harmonic oscillator potential. The results indicate that a sources with thousands of identical pions may exhibit a degree of Bose-Einstein condensation at the temperatures during the hadronic phase in relativistic heavy-ion collisions. This finite condensation may decrease the chaoticity parameter λ in the two-pion interferometry measurements at low pion pair momenta, but influence only slightly the λ value at high pion pair momentum.
