Epidemiology of Renal Palliative Care

ABSTRACT The need for palliative care for patients with end-stage renal disease (ESRD) is increasingly recognized. Patients starting renal replacement therapy are now elderly, with a median age of 65 years, and with multiple comorbid conditions. Quality of life is often poor and with advance care planning, patients can be enabled to make the choice of stopping or not starting dialysis. With planned end-of-life management patients can then choose their place of death. These discussions have to be initiated by the renal team. The involvement of palliative care professionals in patients with ESRD is therefore both educational and the provision of community and hospice care. 124

Main Magnets Design Studies for the Non-scaling Fixed Field Alternating Gradient Accelerator for a Final Acceleration Stage of the Neutrino Factory

Abstract The International Design Study of the Neutrino Factory (IDS-NF) aims to design the next generation facility for the precision neutrino oscillation searches. The non scaling Fixed Field Alternating Gradient Accelerator was proposed for the final muon beam acceleration in order to reduce the cost of the final acceleration. A superconducting magnet design based on the independent multipole coils approach using the ROXIE code is presented. The feasibility of the magnet construction together with the quench limitations is discussed

Origin of the Spin-Orbital Liquid State in a Nearly J=0 Iridate Ba3ZnIr2O9

We show using detailed magnetic and thermodynamic studies and theoretical calculations that the ground state of Ba3ZnIr2O9 is a realization of a novel spin-orbital liquid state. Our results reveal that Ba3ZnIr2O9 with Ir5+ (5d(4)) ions and strong spin-orbit coupling (SOC) arrives very close to the elusive J = 0 state but each Ir ion still possesses a weak moment. Ab initio density functional calculations indicate that this moment is developed due to superexchange, mediated by a strong intradimer hopping mechanism. While the Ir spins within the structural Ir2O9 dimer are expected to form a spin-orbit singlet state (SOS) with no resultant moment, substantial frustration arising from interdimer exchange interactions induce quantum fluctuations in these possible SOS states favoring a spin-orbital liquid phase down to at least 100 mK
