A prospective randomized controlled study comparing outcomes of standard resection and extended resection, including dissection of the nerve plexus and various lymph nodes, in patients with pancreatic head cancer.

Abstract: Objective:To prospectively evaluate the survival benefit of dissection of the nerve plexus and lymphadenectomy in patients with pancreatic head cancer.Background:Despite randomized controlled trials on the extent of surgery in pancreatic cancer, attempts have been made to perform more extended resec

Photosynthesis of formate from CO2 and water at 1% energy efficiency via copper iron oxide catalysis

Abstract: Solar conversion of carbon dioxide and water to value-added chemicals remains a challenge. A number of solar-active catalysts have been reported, but they still suffer from low selectivity, poor energy efficiency, and instability, and fail to drive simultaneous water oxidation. Herein, we report CuFeO2 and CuO mixed p-type catalysts fabricated via widely employed electroplating of earth-abundant cupric and ferric ions followed by annealing under atmospheric air. The composite electrodes exhibited onset potentials at +0.9 V vs. RHE in CO2-purged bicarbonate solution and converted CO2 to formate with over 90% selectivity under simulated solar light (air mass 1.5, 100 mW cm−2). Wired CuFeO2/CuO photocathode and Pt anode couples produced formate for over 1 week at a solar-to-formate energy conversion efficiency of ∼1% (selectivity >90%) without any external bias while O2 was evolved from water. Isotopes and nuclear magnetic resonance analyses confirmed the simultaneous production of formate and O2 at the stand-alone couples.

mSCTP for soft handover in transport layer

Abstract: In this letter, we discuss mobile Stream Control Transmission Protocol (SCTP) for soft handover in the transport layer. From the experimentations on triggering rules for Add-IP and Primary-Change during the handover, it is shown that the aggressive Add-IP and conservative Primary-Change rules provide better throughput.
