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

Background/Aim.Gunshot wounds caused by the automatic rifle M70AB2 (AK-47) 7.62 mm, after the primary surgical management, were closed with delayed primary suture during the next four to seven days.This period coincides with the fibroblastic phase of wound healing.Fibrin glue is used as a local hemostatic and as a matrix for the local dosed release

Plastics are ubiquitous in our daily life.However, the use of petrochemical-based plastic as packaging materials causes the depletion of non-renewable resources, thereby leading to popularfilm.blog an increase in oil prices and economic crises.Moreover, these petrochemical plastics raise the issue of environmental pollution due to their non-biodegr

It is read more of scientific interest to consider the monastic and monastic vision of church-religious, socio-political, ethno-religious problems of the pre-war era in Ukrainian lands.Interest is dictated by the following factors and reasons.First, monastic centers from the time of Kievan Rus remained one of the most stable in the society and in t

Zeugodacus tau (Walker) (Diptera: Tephritidae), is widely distributed throughout South and Southeast Asia.complete sequence of the mitogenome of Z.tau has been determined in this study.The circular genome is 15830 bp long and contains here a standard gene complement, that is, the large and small ribosomal RNA subunits, 22 transfer RNA genes, 13 gen
