We study nonadiabatic two-parameter charge and spin pumping through a single-level quantum dot with Coulomb interaction. For the limit of weak tunnel coupling and in the regime of pumping frequencies up to the tunneling rates, Omega less, similar Gamma/variant Planck's over 2pi, we perform an exact resummation of contributions of all orders in the pumping frequency. As striking nonadiabatic sig...

Abstract Standing wave thermoacoustic refrigerator uses stack, is the heart of cooling system. The porous stack in resonator tube develops temperature difference across for heat pumping upon loudspeaker sound interaction oscillating gas. In this paper, optimization stack-heat exchangers system and discussed using linear theory better COP power refrigerator. assumed to provide required acoustic ...

Excessive wound exudates often cause infection and hinder repair regeneration. It is therefore urgently needed to develop an ideal dressing for pumping the excessive biofluids inhibiting bacterial in healing process. Herein, we demonstrate a facile efficient strategy fabricate unidirectional water-transport antibacterial dressings by embedding macromolecular antimicrobials into multilayer nanof...

Nonevaporable getter (NEG) pumps are widely used in ultra-high vacuum (UHV) apparatus to evacuate residual gasses efficiently UHV of 10–7 Pa or less. NEG can be use oil-free, noise-free, vibration-free, space-saving, energy-saving and low-cost. We have developed a new type pump, named oxygen-free Pd/Ti. A pumping speed the Oxygen-free Pd/Ti did not decrease after repeated cycles pumping, baking...

INTRODUCTION Intra-aortic balloon pumping is used in elective percutaneous coronary intervention for increasing coronary blood flow. However, intra-aortic balloon pumping may decrease visceral blood flow and cause mesenteric ischemia by visceral artery obstruction. CASE PRESENTATION We report the case of a 79-year-old Asian man in whom elective percutaneous coronary intervention was performed...

Mainly due to its long history, sucker-rod pumping is a very popular means of artificial lift all over the world, roughly two-thirds of the producing oil wells are on this type of lift. To maximize profits from these wells in the ever-changing economic situation with rising costs of electric power, installation designs must ensure optimum conditions. In the paper, basic considerations on ensuri...

Recent studies have ascribed many non-pumping functions to the Na/K-ATPase. Here, we present experimental evidence demonstrating that over half of the plasma membrane Na/K-ATPase in LLC-PK1 cells is performing cellular functions other than ion pumping. This "non-pumping" pool of Na/K-ATPase, like the pumping pump, binds ouabain. Depletion of either cholesterol or caveolin-1 moves some of the "n...
