ENHANCED AMPLIFICATION OF ATTOSECOND PULSES IN A HYDROGEN-LIKE PLASMA-BASED X-RAY LASER MODULATED BY AN INFRARED FIELD AT THE SECOND HARMONIC OF FUNDAMENTAL FREQUENCY

In a recent work (Antonov et al., Physical Review Letters 123, 243903 (2019)), it was shown that it is possible to amplify a train of attosecond pulses, which are produced from the radiation of high harmonics of the infrared field of the fundamental frequency, in the active medium of a plasma-based X-ray laser modulated by a replica of the infrared

Conflict of interest: No Introduction and Objectives: Alcohol-associated cirrhosis (AAC) is the leading cause of death from cirrhosis in the world.In recent years, an increase in alcohol consumption and AAC has been observed, especially in women, young people, low socioeconomic levels, and certain ethnic groups.Objective: To perform a descriptive s

Ultraviolet-B (UV-B) radiation from the past few decades has been widely studied due Logo to the substantial depletion of the stratospheric ozone (O3) layer, causing morphological, physiological, cytological, and biochemical alterations in plants.As a potent abiotic stress factor, enhanced reactive oxygen species (ROS) generation has been flagged a

The article offers a systematic analysis of the issues related to the network society as a subject matter of theoretical research.The organizational structures classification is provided primarily to expose the peculiar features of hierarchical and network structures.The origins and sources of network management philosophy Mixing Bowl are pointed o

Replacing part of cement with waste stone powder can reduce the use of cement, thus reducing energy consumption and CO2 emission.Different stone powders affect the properties of cement-based materials differently.It is important to clarify the effect of the surface properties of the stone powder on the properties of cement-based materials.In this p
