Authors: Samoilov Pavel Andreevich 
Published: January 2025

The subject of the study is the influence of information and communication technologies (ICT) on the formation and development of the political ecosystem of society. The article analyzes and compares two key approaches – network and ecosystem, revealing different aspects of the digital transformation of political processes. Particular attention is paid to the need to integrate these approaches for a deeper and more comprehensive analysis of the political ecosystem in the context of digitalization. The author proposes a theoretical model combining network and ecosystem concepts, which allows taking into account both the dynamics of horizontal interactions and the stability of the system. The research covers issues of civic identity, decentralization of power, and self-organization, demonstrating how digital platforms and patriotic content contribute to strengthening social cohesion and transforming the political environment. The work offers the author's definition of the political ecosystem of society, reflecting the complexity and multidimensionality of social processes in the era of digitalization. The research methodology is based on a comparative analysis of network and ecosystem approaches in order to integrate them to create a comprehensive model of the political ecosystem. The analysis of theoretical concepts presented in the works of leading researchers is used, as well as conceptual modeling aimed at forming the author's model of the political ecosystem of society. The novelty of the research lies in the development and substantiation of an integrated model of the political ecosystem, which combines the principles of network and ecosystem approaches. The main conclusions of the study are the provisions that information and communication technologies (ICT) play a key role in the formation of horizontal political structures, ensuring the decentralization of power and self-organization of civil society. A special contribution of the author to the research of the topic is the formulation of the author's definition of a political ecosystem as a dynamic system where information flows and inter-network interactions occupy a central place. An important result of the research is the identification of factors that ensure the stability and adaptability of the political system in the context of digitalization. The practical significance of the work is shown in the possibility of using the developed model to analyze modern political processes, predict their development and form strategies for digital interaction between government institutions and society.

Abstract

Purpose
We investigated occupational dose to the lens of the eye for physicians engaged in radiology procedures. We evaluated the potential for compliance with the new-equivalent dose limits to the lens of the eye. Further, a “multiple radiation protection” protocol was proposed according to the basic principles of occupational health, and its effectiveness was estimated.

Methods
Physicians engaged in radiology procedure at medical facilities in Japan were included in this study. The eye lens dose (3-mm dose equivalent: Hp(3)) for each participant was measured using a small radio-photoluminescence glass dosimeter mounted on lead glasses. Physicians were directed to procedure multiple radiation protection measures to evaluate their usefulness.

Results
The Hp(3) was reduced by multiple radiation protection in all physicians. In particular, the Hp(3) reduced from 207.7 to 43.2 μSv/procedure and from 21.6 to 10.2 μSv/procedure in cardiovascular internal physician and cerebrovascular physician, respectively, after the implementation of the proposed multiple radiation protection measures. The dose reduction rate of these measures was 53% (range: 37%–79%).

Conclusions
The radiation doses received by the eye lenses of physicians engaged in radiology procedure may exceed the dose limits to the lens of the eye if radio-protective equipment and imaging conditions are not properly controlled. However, based on the lens equivalent dose data, the implementation of “multiple radiation protection” according to the basic principles of occupational health can ensure compliance with the new-equivalent dose limits to the lens of the eye without placing an undue burden on individual physicians or medical facilities.

Published: December 2021

AbstractIntroductionThis study presents a comprehensive collision avoidance framework based on three‐dimension (3D) computer‐aided design (CAD) modeling, a graphical user interface (GUI) as peripheral to the radiation treatment planning (RTP) environment, and patient‐specific plan parameters for intensity‐modulated proton therapy (IMPT).MethodsA stand‐alone software application was developed leveraging the Varian scripting application programming interface (API) for RTP database object accessibility. The Collision Avoider software models the Hitachi ProBeat‐V half gantry design and the Kuka robotic couch with triangle mesh structures. Patient‐specific plan parameters are displayed in the collision avoidance software for potential proximity evaluation. The external surfaces of the patients and the immobilization devices are contoured based on computed tomography (CT) images. A “table junction‐to‐CT‐origin” (JCT) measurement is made for every patient at the time of CT simulation to accurately provide reference location of the patient contours to the treatment couch. Collision evaluations were performed virtually with the program during treatment planning to prevent four major types of collisional events: collisions between the gantry head and the treatment couch, gantry head and the patient's body, gantry head and the robotic arm, and collisions between the gantry head and the immobilization devices.ResultsThe Collision Avoider software was able to accurately model the proton treatment delivery system and the robotic couch position. Commonly employed clinical beam configuration and JCT values were investigated. Brain and head and neck patients require more complex gantry and patient positioning system configurations. Physical measurements were performed to validate 3D CAD model geometry. Twelve clinical proton treatment plans were used to validate the accuracy of the software. The software can predict all four types of collisional events in our clinic since its full implementation in 2020.ConclusionA highly efficient patient‐specific collision prevention program for scanning proton therapy has been successfully implemented. The graphical program has provided accurate collision detection since its inception at our institution.

ObjectiveDepression is a prevalent (24–30%) and significant comorbidity in patients with systemic lupus erythematosus (SLE). In the present study, we leveraged the longitudinal SLE cohort at the Washington University Lupus Clinic to address 1) what is the longitudinal course of depressed affect among outpatients with SLE and 2) what is the longitudinal relationship between SLE disease activity and depressed affect?MethodsLongitudinal data from patients with American College of Rheumatology– or Systemic Lupus International Collaborating Clinics–classified SLE were analyzed. Depressed symptoms were assessed at each visit using the Center for Epidemiologic Studies Depression Scale, Revised (CESD‐R), and SLE disease activity was measured via the Systemic Lupus Erythematosus Disease Activity Index 2000 (SLEDAI‐2K). Group‐based trajectory modeling (GBTM) and linear mixed models were used for analysis.ResultsThe study sample (n = 144) was 56.3% Black and 38.9% White. GBTM revealed 5 distinct groups of patients who demonstrated consistent trends in depression over time. Members of groups 4 (n = 44, 30.6%) and 5 (n = 44, 30.6%) demonstrated CESD‐R scores consistent with depression. Of note, Black patients were much more common in group 5 (n = 32, 72.7%, P < 0.02). Analyses identified an association between SLEDAI disease activity and depression scores in multivariate analysis but did not show significance in GBTM and univariate analysis.ConclusionsThe majority (61.2%) of patients had CESD‐R scores consistent with persistent depressed affect or major depression over a period of up to 4 years. The lack of a consistent relationship of CESD‐R with SLE disease activity highlights the need to regularly monitor, treat, and better understand the causes behind this comorbidity.

Published: December 2021

AbstractNoninvasive manipulation of cell signaling is critical in basic neuroscience research and in developing therapies for neurological disorders and psychiatric conditions. Here, the wireless force‐induced stimulation of primary neuronal circuits through mechanotransduction mediated by magnetic microdiscs (MMDs) under applied low‐intensity and low‐frequency alternating magnetic fields (AMFs), is described. MMDs are fabricated by top‐down lithography techniques that allow for cost‐effective mass production of biocompatible MMDs with high saturation and zero magnetic magnetic moment at remanence. MMDs are utilized as transducers of AMFs into mechanical forces. When MMDs are exposed to primary rat neuronal circuits, their magneto‐mechanical actuation triggers the response of specific mechanosensitive ion channels expressed on the cell membranes activating ≈50% of hippocampal and ≈90% of cortical neurons subjected to the treatment. Mechanotransduction is confirmed by the inhibition of mechanosensitive transmembrane channels with Gd3+. Mechanotransduction mediated by MMDs cause no cytotoxic effect to neuronal cultures. This technology fulfills the requirements of cell‐type specificity and weak magnetic fields, two limiting factors in the development of noninvasive neuromodulation therapies and clinical equipment design. Moreover, high efficiency and long‐lasting stimulations are successfully achieved. This research represents a fundamental step forward for magneto‐mechanical control of neural activity using disc‐shaped micromaterials with tailored magnetic properties.
Self‐Assembled Nanowrinkle‐Network‐Structured Transparent Conductive Zinc Oxide for High‐Efficiency Inorganic Light‐Emitting Diodes
Authors: Lee Gun‐Woo , Na Young‐Chae , Lee Sung‐Nam 
Published: December 2021

AbstractA ZnO nanowrinkle network (NWN) film is applied as a transparent conductive electrode (TCE) to improve the light extraction efficiency of inorganic light‐emitting diodes (LEDs). The NWN structures in sol–gel‐derived ZnO films are spontaneously formed by the evaporation of the solvent during prebaking to achieve the gelation of the sol–gel ZnO film. Despite the NWN structure, the optical transmittance of the NWN‐ZnO film prebaked at 130 °C is maintained at ≈92% with respect to that of unmodified glass. However, the optical transmittance of the NWN‐ZnO film prebaked at 150 °C is significantly decreased because of the increase in nanowrinkle density. As a result, the electroluminescence intensity of LEDs having the NWN‐ZnO TCEs increases significantly for the samples prebaked at temperatures up to 130 °C but decreases slightly in those treated at 150 °C. In addition, LEDs having the NWN‐ZnO film show enhanced spectral distribution over wide angles, which is important for lighting applications. On the basis of these results, the spontaneously assembled NWN‐ZnO films formed by the sol–gel method show potential for the low‐cost production of inorganic LEDs having high light extraction efficiencies.

AbstractThe metal/photocatalyst heterojunction has demonstrated an excellent capability for pollutant degradation under visible light irradiation. In this study, for the first time, highly stable colloidal dispersions of Bi/BiOClxBr1−x heterojunction with an exposed (001) facet are successfully prepared from inorganic simple salts using low‐frequency ultrasound irradiation (LFUI) at ambient conditions without further post‐treatment. The colloidal dispersion series of Bi/BiOClxBr1−x heterojunction (x = 0, 0.2, 0.5, 0.8 and 1) is simply obtained by adding stoichiometric aqueous solutions of NaCl and NaBr, into an acidic aqueous solution of Bi(NO)3.5H2O in a typical ultrasonication bath at room temperature within ≈5 min. Bi/BiOClxBr1−x heterojunction films are also fabricated using a simple drop‐casting technique and tested as immobilized photocatalytic reactors. Compared to its counterparts, the Bi/BiOCl0.8Br0.2 film possesses a 3D flower‐like morphology with a highly exposed (001) facet showing the highest electron‐hole generation and separation efficiencies. In addition, the Bi/BiOCl0.8Br0.2 film demonstrates the highest photocatalytic degradation rate of the rhodamine RhB aqueous solutions (≈5 ppm), achieving ≈99% in 60 min under the visible light component of the solar spectrum. This study demonstrates the potential of LFUI as a rapid scalable synthetic strategy for cost‐effective and energy‐efficient practical production of highly active immobilized photocatalytic reactors.

AbstractThe magnetostriction phenomenon, which exists in almost all magnetically ordered materials, is proved to have wide application potential in precision machinery, microdisplacement control, robotics, and other high‐tech fields. Understanding the microscopic mechanism behind the magnetostrictive properties of magnetically ordered compounds plays an essential role in realizing technological applications and helps the fundamental understanding of magnetism and superconductivity. In paramagnets, however, the magnetostriction is usually significantly smaller because of the magnetic disorder. Here, the observation of a remarkably strong magnetostrictive response of the insulator paramagnet KEr(MoO4)2is reported on. Using low‐temperature magnetization and dilatometry measurements, in combination with ab initio calculations, employing a quasi‐atomic treatment of many‐body effects, it is demonstrated that the magnetostriction anomaly in KEr(MoO4)2is driven by a single‐ion effect. This analysis reveals a strong coupling between the Er3+ions and the crystal lattice due to the peculiar behavior of the magnetic quadrupolar moments of Er3+ions in the applied field, shedding light on the microscopic mechanism behind the massive magnetostrictive response.
Resistivity Scaling Transition in Ultrathin Metal Film at Critical Thickness and Its Implication for the Transparent Conductor Applications

Published: December 2021

AbstractUnderstanding of ultrathin metal film's electrical and optical properties at sub‐10 nm thickness may provide important engineering insight on its application as a transparent conductor. Here, a rapid change is observed in the ultrathin metal film's electrical and optical scaling properties as the thickness shrinks to below a certain critical thickness dc. Below this thickness, the metal film's electrical properties are shown to be strongly influenced by the inhomogeneity of the film which can be modeled via general effective media theory by incorporating size‐effect contribution. As a result, below dc, carrier's scattering time rapidly decreases with a reduced mean free path leading to a rapid rise in resistivity. Also, the film's optical loss increases while the optical transmission plateaus below dc. As one promising application of thin metal film is transparent conductor where the film's electrical and optical properties are equally important, its maximum theoretical figure‐of‐merit is shown, which is determined at this dc serving as an important engineering metric.
Evaluating the demand response potential of ammonia plants

Published: December 2021

AbstractDemand‐side management/demand response (DSM/DR) are key strategies for mitigating the inherent variability in electricity generation rates by renewable sources. This article represents—to our knowledge—the first foray into assessing the DR potential of ammonia plants. Ammonia plants are interesting candidates for DR initiatives because of their significant electricity use (for operating compressors driving the synthesis loop) and the ability to store the ammonia product relatively easily and safely. Our approach is based on formulating and solving an optimal DR scheduling problem for an ammonia plant while accounting for the process dynamics. To this end, we introduce a new Hammerstein–Wiener‐inspired modeling framework based on injecting linear dynamics in a first‐principles static nonlinear model of the process. The results are encouraging; for the cases considered, peak‐time power consumption decreases between 3.57% and 7.40%, coupled with 1.39% to 3.70% reductions in operating cost.
