Quantum walks with nonorthogonal position states.

Quantum walks have by now been realized in a large variety of different physical settings. In some of these, particularly with trapped ions, the walk is implemented in phase space, where the corresponding position states are not orthogonal. We develop a general description of such a quantum walk and show how to map it into a standard one with orthogonal states, thereby making available all the tools developed for the latter.

The effect of plasma volume expansion on the response to carotid occlusion in the non-human primate.

The purpose of this study was to investigate the effects of plasma volume expansion on the cardiac and peripheral components of the baroreceptor reflex. Nine male Rhesus monkeys were chronically instrumented to measure arterial pressure and aortic blood flow. The aortic arch was denervated at the time of surgery.

Hormonal and renal response to plasma volume expansion in the primate Macaca mulatta.

The purpose of this study was to investigate the hormonal and renal response to plasma volume expansion in the ketamine-anesthetized rhesus monkey. The blood volume was determined in nine animals and found to be 6% of the body weight. Six monkeys received isoncotic isotonic fluid amounting to 25% of the blood volume.

Constituents of lymph from the non-secreting stomach of the dog.

Gastric lymph collected from the non-secreting stomach of anesthetized dogs contained glucose, Na+, K+ and creatine phosphokinase in concentrations that were similar to those in arterial and gastric venous plasma. Gastric lymph contained greater concentrations of pyruvate and lactate than in either arterial or gastric venous blood. Gastric lymph contained a high concentration of total protein similar to that in simultaneously collected hepatic lymph.

Comparison of renal and cardiac lymph constitutents.

The concentration of various substances were measured in renal and cardiac lymph and arterial and venous plasma to determine if lymph constituents might indicate events occurring at the cellular level in these two organs. The study utilized anesthetized dogs. Magnesium, calcium, pyruvate and glucose concentrations were similar in the four fluids.
