Complex Monge–Ampère equations with solutions in finite energy classes [PDF]

Mathematical Research Letters, 2020
We characterize the class of probability measures on a compact Kahler manifold such that the associated Monge-Ampere equation has a solution of finite pluricomplex energy. Our results are also valid in the big cohomology class setting.

Snow microbiome functional analyses reveal novel aspects of microbial metabolism of complex organic compounds

MicrobiologyOpen, 2020
Microbes active in extreme cold are not as well explored as those of other extreme environments. Studies have revealed a substantial microbial diversity and identified cold‐specific microbiome molecular functions.

Engineering active and robust alloy-based electrocatalyst by rapid Joule-heating toward ampere-level hydrogen evolution

Nature Communications
Rational design of bimetallic alloy is an effective way to improve the electrocatalytic activity and stability of Mo-based cathode for ampere-level hydrogen evolution. However, it is still critical to realise desirable syntheses due to the wide reduction

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 exterior Dirichlet problems of Monge–Ampère equations in dimension two

Boundary Value Problems, 2020
In this paper, we study the Monge–Ampère equations det D 2 u = f $\det D^{2}u=f$ in dimension two with f being a perturbation of f 0 $f_{0}$ at infinity.

Generation of Coherent X-Ray Radiation Through Modulation Compression

, 2010
In this paper, we propose a scheme to generate tunable coherent X-ray radiation for future light source applications. This scheme uses an energy chirped electron beam, a laser modulator, a laser chirper and two bunch compressors to generate a prebunched ...
