Leibniz, M. Bugayov, M. Rudenko is made. The points of contact and differences in the reasoning of scientists are determined. The uniqueness of the theory of monads of M. Rudenko was proved, which was the first in world science to bring out the physical characteristics of the Monad: he calculated the radius, mass, density, energy and proved that the Monad can be densified and create a gravitational field
Imaging single cells in a beam of live cyanobacteria with an X-ray laser

Imaging single cells in a beam of live cyanobacteria with an X-ray laser. Nature Communications, 6, 9. doi:10.1038/ncomms6704There exists a conspicuous gap of knowledge about the organization of life at mesoscopic levels. Ultra-fast coherent diffractive imaging with X-ray free-electron lasers can probe structures at the relevant length scales and may reach sub-nanometer resolution on micron-sized living cells. Here we show that we can introduce a beam of aerosolised cyanobacteria into the focus of the Linac Coherent Light Source and record diffraction patterns from individual living cells at very low noise levels and at high hit ratios. We obtain two-dimensional projection images directly from the diffraction patterns, and present the results as synthetic X-ray Nomarski images calculated from the complex-valued reconstructions. We further demonstrate that it is possible to record diffraction data to nanometer resolution on live cells with X-ray lasers. Extension to sub-nanometer resolution is within reach, although improvements in pulse parameters and X-ray area detectors will be necessary to unlock this potential.Additional Authors: Almeida, N.

Three-Dimensional Reconstruction of the Giant Mimivirus Particle with an X-Ray Free-Electron Laser

Three-Dimensional Reconstruction of the Giant Mimivirus Particle with an X-Ray Free-Electron Laser. Physical Review Letters, 114(9), 6. doi:10.1103/PhysRevLett.114.098102We present a proof-of-concept three-dimensional reconstruction of the giant mimivirus particle from experimentally measured diffraction patterns from an x-ray free-electron laser. Three-dimensional imaging requires the assembly of many two-dimensional patterns into an internally consistent Fourier volume. Since each particle is randomly oriented when exposed to the x-ray pulse, relative orientations have to be retrieved from the diffraction data alone. We achieve this with a modified version of the expand, maximize and compress algorithm and validate our result using new methods.Additional Authors: Andersson, I.;Loh, N. D.;Martin, A.

Monadology of Mykola Rudenko: Uniqueness and Originality of Scientific Platform

Теорія Монад українського філософа пропонує як альтернативну стаціонарну (на відміну від відомої нам ізотропної) модель Всесвіту, у якій все ґрунтується на принципі загального порядку без жодних випадковостей.Monadology is not a new science.

Rudenko, the first in the world of science, gave physical characteristics of the Monad: he calculated the radius, mass, density, energy and proved that the Monad can thicken and create a gravitational field.
M. Rudenko offers a stationary (unlike known isotropic) model of the Universe, in which everything is based on the principle of general order without any eventualities.

Monad, or Nine: six forces that create the Sphere, and three additional ones – Free Light, Light Creator. The Light is spilled inside the Monads. The Monad should be seen as the Spirit Matter. There are no other realities in the world except the Monads. The thinker proves that life on the Earth does not originate from the Sun but from the World Monad. M.

Monadology of Mykola Rudenko: uniqueness and originality of scientific platform
No full textУ статті зроблено критичний аналіз наукової праці М. Руденка “Гносис і сучасність”, де автор, взявши за об’єкт аналізу гравітаційні потенціали й радіуси, виклав власну теорію будови Всесвіту. Глибокі наукові дослідження письменника-філософа є синтезом фізики і метафізики, підтверджені математичними розрахунками. М. Руденко пропонує ввести до наукового обігу четверту світову константу – Силу Моносу, яка, на думку дослідника, лежить в основі світобудови. Письменник доводить первинність матерії – основи для розвитку природи і вказує на вторинність речовинних об’єктів, сповнених прагнення до життя.Monadology is not a new science.

Embedded nanogratings in bulk fused silica under non-diffractive Bessel ultrafast laser irradiation
No full text
We report the formation of embedded nanogratings in bulk fused silica under quasi- stationary field patterns generated by ultrashort laser pulses in nondiffractive modes. The zero- order Bessel beam consists of almost non- propagative light pulses distributed along a narrow micron- sized channel sustained over a large non- diffracting length. Upon multipulse irradiation, a regular pattern of nanoplanes is formed across the channel, spaced at approximately lambda/2n. Applying an electromagnetic scattering model [A. Rudenko et al., Phys. Rev. B 93, 075427 (2016)], we associate the formation of nanogratings with multiple scattering from randomly distributed scattering centers created by laser light. Constructive interference between the scattered wavelets leads to periodic excitation enhancement without requiring explicit synchronism conditions. Permanent material modifications are found whenever the local carrier densities are maximized towards the critical value. Multiple periodicities are predicted, either implicitly related to the coherent electromagnetic interaction or due to periodic field depletion and photon replenishment.

Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
