The Quantum Backflow Phenomenon [PDF]
It has been known since at least 1969, that there exist quantum states of a free particle on the line with purely positive momentum that exhibit probability transfer towards the negative half-line.

An enigmatic route to the contralateral pelvicalyceal system on antegrade pyelogram
Introduction: The authors present the rare yet enigmatic phenomenon of ‘pyelo-renal’ backflow. Case Presentation: An eight-month-old boy with multiple congenital anomalies underwent left Anderson-Hynes Pyeloplasty for pelvi-ureteric junction obstruction.

Hydrodynamics and sediment transport in Poyang Lake under the effects of wind and backflow
The ecology of the aquatic environment in Poyang Lake, the largest fresh lake in China, is notably impacted by the backflow from the Yangtze River, which conveys a high flux of sediments.

Simulations to Eliminate Backflow Power in an Isolated Three-Port Bidirectional DC–DC Converter
The aim of this work was to eliminate the backflow power present in an isolated three-port DC–DC converter. Backflow power (which is an inherent property of phase-shifted DC–DC converters) is the major contributor of circulating current the converter ...

Spud-Can Penetration Response in Double Layered Soil by Press-Replace Technique [PDF]
One of the most important factors in the process of jack-up rig installation is the good expectation of the amount of spud-can penetration into soil layers under the varying loads.

Backflow in relativistic wave equations
We show that, contrary to the statements made by many authors, the backflow is not a nonclassical effect. The backflow is a characteristic feature of solutions of the wave equations: quantum and classical.

Experimental Study on Backflow Patterns Induced by a Bilateral Groin Pair with Different Spacing
Groins are one of the popular manmade structures to modify the hydraulic flow and sediment response in river training. The spacing between groins is a critical consideration to balance the channel-depth and the cost of construction, which is generally ...
