The space of solutions to the Hessian one equation in the finitely punctured plane [PDF]
, 2004 We construct the space of solutions to the elliptic Monge-Ampere equation det(D^2 u)=1 in the plane R^2 with n points removed. We show that, modulo equiaffine transformations and for n>1, this space can be seen as an open subset of R^{3n-4}, where the ...

Generation of Multi-Color Attosecond X-Ray Radiation Through Modulation Compression
, 2011 In this paper, we propose a scheme to generate tunable multi-color attosecond coherent X-ray radiation for future light source applications. This scheme uses an energy chirped electron beam, a laser modulators, a laser chirper and two bunch compressors ...

, 2013 We develop a differential theory for the polarity transform parallel to that for the Legendre transform, which is applicable when the functions studied are "geometric convex", namely convex, non-negative and vanish at the origin.

THE EFFECT OF γ-RADIATION ON THE ELECTRICAL AND OPTICAL CHARACTERISTICS OF InGaN / GaN LEDS
Известия высших учебных заведений. Поволжский регион: Физико-математические науки, 2020 Background. Despite the fact that InGaN / GaN-based structures have firmly conquered the LED market, some issues remain unresolved about how the electrical and optical characteristics of LEDs based on them change under the influence of external ...

The Monge-Ampere equation: various forms and numerical methods
, 2010 We present three novel forms of the Monge-Ampere equation, which is used, e.g., in image processing and in reconstruction of mass transportation in the primordial Universe.

The NBS Absolute Ampere Experiment [PDF]
IEEE Transactions on Instrumentation and Measurement, 1985 We have constructed a current balance with superconducting field coils for the realization of the SI ampere by comparing mechanical to electrical work. The estimated ultimate accuracy of the realization is 0.1 ppm. We describe and present preliminary results obtained with a room temperature version of the apparatus.

Oil-Contaminated Soil Modeling and Remediation Monitoring in Arid Areas Using Remote Sensing
Remote Sensing, 2022 Oil contamination is a major source of pollution in the environment. It may take decades for oil-contaminated soils to be remedied. This study models oil-contaminated soils using one of the world’s greatest environmental disasters, the onshore oil spill ...
