Evaluation of Short-Term Effects on Colorectal Surgery Elective Patients after Implementing a Patient Blood Management Program: A Multicenter Retrospective Analysis.

: Patients who undergo surgery may require a blood transfusion and patients undergoing major colorectal surgery are more prone to preoperative and perioperative anemia. Blood transfusions have, however, long been associated with inflammatory and oncological complications. We aim to investigate the effects of an optimal implementation of a patient blood management (PBM) program in our hospital.

Observation of Medium-Induced Yield Enhancement and Acoplanarity Broadening of Low-p_{T} Jets from Measurements in pp and Central Pb-Pb Collisions at sqrt[s_{NN}]=5.02 TeV.

The ALICE Collaboration reports the measurement of semi-inclusive distributions of charged-particle jets recoiling from a high transverse momentum (high p_{T}) hadron trigger in proton-proton and central Pb-Pb collisions at sqrt[s_{NN}]=5.02  TeV. A data-driven statistical method is used to mitigate the large uncorrelated background in central Pb-Pb collisions.

Photoproduction of K^{+}K^{-} Pairs in Ultraperipheral Collisions.

K^{+}K^{-} pairs may be produced in photonuclear collisions, either from the decays of photoproduced ϕ(1020) mesons or directly as nonresonant K^{+}K^{-} pairs. Measurements of K^{+}K^{-} photoproduction probe the couplings between the ϕ(1020) and charged kaons with photons and nuclear targets. The kaon-proton scattering occurs at energies far above those available elsewhere.
