Abstract
Laser-induced transformations of plasmonic metasurfaces pave the way for controlling their anisotropic optical response with a micrometric resolution over large surfaces. Understanding the transient state of matter is crucial to optimize laser processing and reach specific optical properties. This article proposes an experimental and numerical study to follow and explain the diverse irreversible transformations encountered by a random plasmonic metasurface submitted to multiple femtosecond laser pulses at a high repetition rate. A pump-probe spectroscopic imaging setup records pulse after pulse, and with a nanosecond time resolution, the polarized transmission spectra of the plasmonic metasurface, submitted to 50,000 ultrashort laser pulses at 75 kHz. The measurements reveal different regimes, occurring in different ranges of accumulated pulse numbers, where successive self-organized embedded periodic nanostructures with very different periods are observed by post-mortem electron microscopy characterizations. Analyses are carried out; thanks to laser-induced temperature rise simulations and calculations of the mode effective indices that can be guided in the structure. The overall study provides a detailed insight into successive mechanisms leading to shape transformation and self-organization in the system, their respective predominance as a function of the laser-induced temperature relative to the melting temperature of metallic nanoparticles and their kinetics. The article also demonstrates the dependence of the self-organized period on the guided-mode effective index, which approaches a resonance due to system transformation. Such anisotropic plasmonic metasurfaces have a great potential for security printing or data storage, and better understanding their formation opens the way to smart optimization of their properties.

Abstract
To the best of our knowledge, such a detailed study on polychrome wooden shawabtis of King Tutankhamun (18th Dynasty in ancient Egypt) has not been reported in the literature, so the purpose of our study is to noninvasively identify the polychrome layers and previously applied materials for a number of wooden shawabtis that belong to King Tutankhamun through a protocol based on imaging techniques integrated with single-spot spectroscopic techniques. In the first step, imaging techniques (visible, ultraviolet induced visible luminescence, ultraviolet reflected, visible-induced infrared luminescence, infrared reflected, and infrared false color) and optical microscopy were applied to gather information and provide evidence on the distribution of original and previously applied materials on the polychrome surfaces. In the second step of our work, we analyzed the selected areas with single-spot analyses (handheld X-ray fluorescence spectroscopy and visible reflectance spectroscopy) and X-ray diffraction analysis. The materials of the previous restoration interventions were studied by Fourier transform infrared spectroscopy. The application of a protocol based on imaging techniques integrated with data obtained from single-spot spectroscopic techniques allowed the characterization of a remarkable number of polychrome layers and some previous restoration materials and mapping of their distribution on the original surface, which provides not only essential data for the follow-up treatment and conservation works but also offers important information for the study of polychrome wooden shawabtis of other periods in ancient Egypt.
Modifying the diet and gut microbiota to prevent and manage neurodegenerative diseases

Published: March 2022

Abstract
The global prevalence of Alzheimer’s disease and Parkinson’s disease is steadily increasing due to the aging population. The lack of effective drugs against these neurodegenerative disorders makes it imperative to identify new strategies for their prevention and treatment. Recent studies have revealed that harnessing the power of the gut microbiota through modification of diet may be a valuable approach for reducing the risk, modulating the symptoms, and ameliorating the pathophysiological aspects of neurodegenerative diseases. Consuming specific dietary components can alter the prevalence of bacterial communities within the gut to a healthy enterotype, which can influence the production of beneficial metabolites by microbiota. This article focuses on several dietary components, which have been demonstrated to affect the gut microbiota–brain axis and therefore could lead to attenuation of specific pathological processes in neurodegenerative diseases. Published evidence indicates that fermented foods, including kefir, and foods that are high in bioactive polyphenols and complex carbohydrates, such as grapes, pomegranates, and seaweed, may be effective at reducing neuroinflammation, oxidative stress, neurotransmitter dysfunction, and neuronal death associated with Alzheimer’s and Parkinson’s diseases. Even though experimental evidence supporting the protective properties of the above dietary components in these diseases is emerging, it is evident that further human clinical studies are required to conclusively establish the benefits of any suggested dietary interventions. The translational potential of such research is illustrated by the clinical success of the recently developed Alzheimer’s drug, GV-971, which is a seaweed derivative that works by modulating the gut microbiota–brain axis.

Funktionsprinzip und Anwendung der Kraftkompensationsmessmethode für miniaturisierte hydrogelbasierte Sensoren
Authors: Binder Simon , Gerlach Gerald 
Published: March 2022

Zusammenfassung
Chemische Sensoren, die ein Stimulus-responsives Hydrogel als Messaufnehmer nutzen, bieten viele Vorteile. Die Hydrogele sind kostengünstig, einfach in der Herstellung und für verschiedenste Messgrößen auslegbar. Sensoraufbauten, die den stimulusabhängigen Quelldruck in ein elektrisches Messsignal wandeln, sind gut miniaturisierbar und als Plattform für verschiedene Hydrogelarten nutzbar. Wesentliche Nachteile hydrogelbasierter Sensorprinzipien sind jedoch das Kriechen und die langen Einstellzeiten im Minuten- bis Stundenbereich, die durch langwierige Diffusionsprozesse und das viskoelastische Verhalten der Hydrogele bedingt sind. Die Kraftkompensation ist eine Messmethode diesen beiden Effekten erfolgreich entgegenzuwirken, indem der zeittreibende Volumenphasenübergang des Hydrogels unterdrückt wird. Der hierfür benötigte Aktor verhinderte in früheren Arbeiten jedoch eine Miniaturisierung der Sensoraufbauten. In dieser Arbeit ist daher eine andere Art der Kraftkompensation gezeigt, welche es erlaubt, die vielen Vorteile der Kraftkompensationsmethode auf einen Hydrogelsensor anzuwenden, aber gleichzeitig geringe Abmessungen des Sensoraufbaus zu gewährleisten. Dies gelingt, indem der quellunterdrückende Aktor direkt in den Hydrogel-Messwandler hineinverlegt wird. Auf diese Weise geschieht die Quelldruck-Kompensation im Hydrogel selbst. Zu diesem Zweck ist das Hydrogel als bisensitives Hydrogel ausgelegt. Im Ergebnis verkleinert und vereinfacht sich der Sensoraufbau durch den Wegfall aufwändiger Aktoraufbauten deutlich. Gleichzeitig wird dennoch eine hohe Einstellzeitverkürzung gegenüber der herkömmlichen unkompensierten Messmethode erreicht und die bisherigen Kompensationsansätze mit einer minimalen Einstellzeit von ca. 3 min übertroffen. Es zeigt sich überdies eine signifikante Reduktion unerwünschter Hystereseeigenschaften und die Möglichkeit zur Messbereichserweiterung. Die Messmethode ist am Beispiel eines piezoresistiven Hydrogelsensors gezeigt und prinzipiell auf andere hydrogelbasierte Sensorprinzipien zur Verbesserung der Sensoreigenschaften übertragbar.
Effect of G-type integral squeeze film damper on the dynamic characteristics in rotor system

Abstract
To solve the problems of the nonlinear damping force in the traditional squeeze film damper (SFD), a novel structure of G-type integral squeeze film damper (GISFD) based on ISFD is proposed for the first time. The finite element model and test rig of the ball bearing-rotor system are established to explore the influence of GISFD and ISFD on the dynamic characteristics of the unbalanced rotor system. The results show that both GISFD and ISFD can change the critical speed of the rotor system, reduce the bending strain energy of the shaft, and reduce the bearing dynamic load of the rotor system. Through comparison, it is found that the effect of GISFD is more obvious. The experimental results show that, compared with the unbalanced rotor system without damper, the peak-peak value of amplitude in the rotor system with GISFD and ISFD at 3000 rpm is reduced by 25.53 and 15.81%. The amplitude in the disk at the first-order critical speed is effectively reduced, and the reduction range reach 52.01 and 35.44%, respectively. GISFD has a more significant effect of suppressing unbalanced vibration, and has superior vibration damping performance when compared with ISFD.

Abstract
Colorless rubidium thiocyanate was synthesized by three different approaches. DCS-TGA measurements allowed for extraction of phase transition, melting, and decomposition temperatures. Single-crystal X-ray diffraction showed Rb[SCN] to crystallize in the low-temperature LT-K[SCN] crystal structure type (Pbcm, oP16). Above its phase-transition temperature (432.1 K) the title compound crystallizes with the high-temperature HT-K[SCN] crystal structure type (I4/mcm, tI28) with head-to-tail disordered thiocyanate anions. Both modifications are related to one another and to the LT/HT-Cs[SCN] structure types, and the relation has been studied in detail employing the Bärnighausen formalism. Phase purity and bulk phase transition were confirmed by temperature-dependent PXRD.

Published: March 2022

Abstract
Affected by the surrounding injection and production wells, the formation near the infill adjustment well is in an abnormal pressure state, and drilling and completion operations are prone to complex situations and accidents such as leakage and overflow. The conventional shut down method is to close all water injection wells within 500 meters from the adjustment well to ensure the safety of the operation, but at the same time reduce the oil field production. This paper proposes a design method for shut-in of water injection wells around adjustment wells based on injection-production data mining. This method is based on the influence of correlation of complex pressure wells under injection and production conditions, and uses water injection index and fluid production index as research objects. Data mining methods are used to find highly correlated wells for precise adjustment instead of conventional adjustment. This method was applied to 20 infill adjustment wells in the Penglai Oilfield in Bohai Sea. The correlation between injection and production wells was calculated using the water injection index and fluid production index of more than 500 injection wells and production wells. Controlling the precise shut-in of highly correlated wells ensures that well pressures are kept within safe limits during drilling and completion operations and that no abnormalities occur. Low-relevant wells do not take shut-in adjustment measures. After a single adjustment well is drilled, the surrounding injection wells can increase the water injection volume by more than 5000m3. This method achieves accurate shut-in for water injection wells that are highly correlated with the adjustment well. Under the premise of ensuring the safety of drilling operations, the impact of adjusting drilling and completion on oilfield development is minimized, and oilfield production efficiency is improved. It has good application and promotion value.

Abstract
Large volume of CO2 injection into the saline aquifer is considered to be the high potential CO2 storage method. Until now, the field of CO2 injectivity has been completely dominated by salt precipitation – and by far the most studied mechanism for the loss of injectivity. In this paper, our aim is to focus on recent findings on CO2 injectivity impairment by fines migration that should not be overlooked. This paper summarizes the state-of-the-art knowledge obtained from theoretical, field studies, and experimental observations on CO2 injectivity impairment by fines migration in saline aquifers in the sense of CO2 storage. By gathering various data from books, DOE papers, field reports and SPE publications, a detailed and high quality data set for fines migration during CO2 injection into saline aquifer is created. Key reservoir/fluid/rock information, operational parameters and petrophysical evaluations are assessments are provided, providing the basis for comprehensive data analysis. The results are presented in terms of boxplot and histogram, where histogram displays the distribution of each parameter and identifies the best suitable ranges for best practices; boxplots are used to detect the special cases and summarize the ranges of each parameter. Previous coreflooding experiments concluded that salt precipitation, mineral precipitation, dissolution and mobilization are the main mechanisms that caused CO2 injectivity impairments. Dissolution of carbonate minerals is dominant and it increases the poro spaces and connectivity of sandstone core samples. Conversely, detachment, precipitation of salt and clay minerals and deposition of fines particles decreases the flow are and even clog the flow paths despite net dissolution. However, the results are case dependent and lack generality in terms of quantifying the petrophysical damage. It has been highlighted that injection scheme (flow rate, time frame), mineral composition (clay content, sensitive minerals), particulate process in porous media (pore geometry, particle and carrier fluid properties), and thermodynamic conditions (pressure, temperature, salinity, CO2 and brine composition) give substantial effect on the fines migration during CO2 injection. Additionally, the current experimental work is limited to rendering time and difficult to identify the dynamic process of fines migration during CO2 injection. A list of potential additional work has therefore been presented in this paper including the establishment of microscopic visualization of CO2-brine-rock interactions with representative pore-network under reservoir pressure and temperature. This is the first paper to summarize the contribution of fines migration on CO2 injectivity impairment in saline aquifer.
Legal bases for prosecution of medical staff for illegal acts during the soviet and post-soviet periods
Authors: Kobets P. N. 
Published: March 2022

Objective: to study the historical retrospective of the Soviet (1917-1991) and post-Soviet (1991 – present) periods of healthcare, the evolution of their legal support; to conduct a comprehensive criminological study and analysis of the criminal liability of medical staff who committed illegal acts in the historical periods under consideration.Methods: the methodological basis of the study was the methods of analysis, synthesis, comparison, formal and logical approach. In addition, the author used specific scientific methods, including the historical one.Results: in general, the analysis of the legal foundations of criminal prosecution of medical staff who committed illegal acts during the Soviet and post-Soviet period suggests that the institute of legal liability of medical staff, the medical science and practice developed in parallel under the influence of social, economic and political factors. Since the beginning of the Soviet period, the issues of liability of medical staff have caused numerous disputes among both researchers and practitioners, and today these disputes continue and do not subside. At the same time, it is important to emphasize that the Russian legislative system in the field of healthcare has always been formed solely with the special attitude of the state and society to medical staff, who were perceived as guardians of the health of the citizens and enjoyed their confidence, which in turn gave rise to special caution and responsibility among medical personnel.Scientific novelty: the study is distinguished by the author’s unique approach, which allowed stating the social conditionality of legal prohibitions for the illegal acts under consideration, as well as the causal relationship between the regulatory legal framework formed and the social consequences generated by it in the Soviet and post-Soviet periods.Practical significance: the conclusions obtained by studying the genesis of the problems related to the liability of medical personnel for committing illegal acts will contribute to the development of a scientific understanding of the essence of the phenomenon under consideration, as well as the identification of a modern causal complex contributing to the occurrence of these illegal acts.
Role of cinematography in anticorruption enlightenment: global experience
Authors: Melnikova A. L. , Mitsul A. S. 
Published: March 2022

Objective: to conduct a comprehensive interdisciplinary legal study of the role of cinematography in anti-corruption enlightenment of citizens.Methods: a structural and functional approach to the interpretation of society as a connection of subsystems, in which cinematography is a part of the cultural subsystem, while anti-corruption policy refers simultaneously to the public subsystem (enlightenment) and the state subsystem (politics). The chosen approach determines a set of specific research methods, such as a critical analysis of theoretical literature on corruption behavior and on the relationship between a viewer and a cinematography product in conjunction with an empirical study of various cases in the form of films and film projects devoted to anti-corruption topics.Results: the analysis of the mechanisms of building the relationships between a viewer and cinematography allowed identifying the possibilities of cinematography to have a long-term impact on a viewer, due not only to the technical capabilities of cinematography, but also to the psychobiological mechanisms of man. By the example of specific projects, the expediency of using cinema as an anti-corruption enlightenment tool was proved and justified. In particular, if the relevant messages are laid in the plot of a feature film, then, thanks to mirror neurons and human thinking mechanisms, they can serve educational purposes and demonstrate the consequences of corrupt behavior. It is important not to intimidate the audience with the horrors of living with corruption, but to show a positive way out and scenarios of living without it. This can lead to an increase in civic engagement, to an increase in interest in the issue under discussion, as well as to an increase in ratings of trust in the state.Scientific novelty: the article proves the inexpediency of evaluating cinema solely as a form of entertainment, and for the first time examines examples of the practical application of cinema for anti-corruption policy and enlightenment by comparing approaches used in different countries.Practical significance: the main conclusions of the article can be used in scientific, pedagogical and practical activities when developing long-term strategies and programs of anti-corruption enlightenment, as well as in the framework of cinematographic activities to assess the long-term consequences of the demonstrated film narrative.
