TL;DR: In this paper, the progress, current status, and open challenges of QCD-driven physics, in theory and in experiment, are highlighted, highlighting how the strong interaction is intimately connected to a broad sweep of physical problems, in settings ranging from astrophysics and cosmology to strongly coupled, complex systems in particle and condensed-matter physics, as well as searches for physics beyond the Standard Model.
Abstract: We highlight the progress, current status, and open challenges of QCD-driven physics, in theory and in experiment. We discuss how the strong interaction is intimately connected to a broad sweep of physical problems, in settings ranging from astrophysics and cosmology to strongly coupled, complex systems in particle and condensed-matter physics, as well as to searches for physics beyond the Standard Model. We also discuss how success in describing the strong interaction impacts other fields, and, in turn, how such subjects can impact studies of the strong interaction. In the course of the work we offer a perspective on the many research streams which flow into and out of QCD, as well as a vision for future developments.

TL;DR: In this paper, the spectra and molar absorbances of the HO2 and O2- free radicals have been determined in aqueous formate solutions by pulse and stopped-flow radiolysis as well as by 60Co gamma-ray studies.
Abstract: — The spectra and molar absorbances of the HO2 and O2- free radicals have been redetermined in aqueous formate solutions by pulse and stopped-flow radiolysis as well as by 60Co gamma-ray studies. The extinction coefficients at the corresponding maxima and 23°C are 225= 1400 ± 80 M-1 cm-1 and 225= 2350 ± 120 M-1 cm-1 respectively. Reevaluation of earlier published rate data in terms of the new extinction coefficients yielded the following rate constants for the spontaneous decay of HO2 and O2-: KHo2+HO2= (8.60 ± 0.62) × 105M-1 s-1; KHo2+O2-= (1.02 ± 0.49) × 108M-1 s-1; KHo2+O2- < 0.35 M-1 s-1. For the equilibrium HO2 O2-+ H+ the dissociation constant is KHo2= (2.05 ± 0.39) × 10-5M or pKHO2= 4.69 ± 0.08. G(O2-) has been evaluated as a function of formate concentration.

TL;DR: These findings show that the two c-myc proteins are derived from alternative translational initiations at the exon 2 AUG and at a non-AUG codon near the 3' end of exon 1, resulting in the production of proteins with distinct N termini.

TL;DR: The synthesis, characterization, and electrochemical performance of novel, ultrathin Pt monolayer shell-Pd nanowire core catalysts, activated by the use of two distinctive treatment protocols followed by selective CO adsorption in order to selectively remove undesirable organic residues are reported on.
Abstract: We report on the synthesis, characterization, and electrochemical performance of novel, ultrathin Pt monolayer shell–Pd nanowire core catalysts. Initially, ultrathin Pd nanowires with diameters of 2.0 ± 0.5 nm were generated, and a method has been developed to achieve highly uniform distributions of these catalysts onto the Vulcan XC-72 carbon support. As-prepared wires are activated by the use of two distinctive treatment protocols followed by selective CO adsorption in order to selectively remove undesirable organic residues. Subsequently, the desired nanowire core–Pt monolayer shell motif was reliably achieved by Cu underpotential deposition followed by galvanic displacement of the Cu adatoms. The surface area and mass activity of the acid and ozone-treated nanowires were assessed, and the ozone-treated nanowires were found to maintain outstanding area and mass specific activities of 0.77 mA/cm2 and 1.83 A/mgPt, respectively, which were significantly enhanced as compared with conventional commercial Pt...

TL;DR: The beam energy and collision centrality dependence of the mean, standard deviation, skewness, and kurtosis of the net-proton multiplicity distributions in Au+Au collisions and the products of moments are found to be significantly below the Skellam expectation and close to expectations based on independent proton and antiproton production.
Abstract: We report the beam energy (root S-NN = 7.7-200 GeV) and collision centrality dependence of the mean (M), standard deviation (sigma), skewness (S), and kurtosis (kappa) of the net-proton multiplicity distributions in Au + Au collisions. The measurements are carried out by the STAR experiment at midrapidity (vertical bar y vertical bar < 0.5) and within the transverse momentum range 0.4 < p(T) < 0.8 GeV/c in the first phase of the Beam Energy Scan program at the Relativistic Heavy Ion Collider. These measurements are important for understanding the quantum chromodynamic phase diagram. The products of the moments, S sigma and K sigma(2), are sensitive to the correlation length of the hot and dense medium created in the collisions and are related to the ratios of baryon number susceptibilities of corresponding orders. The products of moments are found to have values significantly below the Skellam expectation and close to expectations based on independent proton and antiproton production. The measurements are compared to a transport model calculation to understand the effect of acceptance and baryon number conservation and also to a hadron resonance gas model.
