Molecular dynamics simulation of microstructure and thermophysical properties of LiCl–CaCl2eutectic molten salt
Authors: Liang Jinglong , Zhang Huilin , Huo Dongxing , Li Hui 
Published: January 2024

AbstractChloride molten salt systems are widely used as electrolytes for molten salt electrolysis because of their relatively low eutectic temperatures and good thermal stability, but there is a serious lack of data on the thermophysical properties of chloride molten salts at elevated temperatures, whereas the nature of the electrolyte is very important for the electrolysis process. In this paper, the variation of the microstructure and thermophysical properties of the binary mixed LiCl–CaCl2molten salt system with temperature and composition is calculated using molecular dynamics (MD) simulations based on the BMH potential. The microscopic conformations observed in LiCl–CaCl2molten salts are mainly irregular, distorted tetrahedra and octahedra, which dynamically coexist, as analyzed by the radial distribution function, coordination number and angular distribution function. In addition, the effects of temperature and composition on the density, ionic self-diffusion coefficient, shear viscosity, and ionic conductivity of the molten salts were investigated, and the relationships of the thermophysical properties of LiCl–CaCl2molten salts with temperature and composition were obtained, which provide fundamental thermophysical data for the molten salt electrolytes.
A discretizing Tikhonov regularization method via modified parameter choice rules
Authors: Zhang Rong , Xie Feiping , Luo Xingjun 
Published: January 2024

Abstract
In this paper, we propose two parameter choice rules for the discretizing Tikhonov regularization via multiscale Galerkin projection for solving linear ill-posed integral equations. In contrast to previous theoretical analyses, we introduce a new concept called the projection noise level to obtain error estimates for the approximate solutions. This concept allows us to assess how noise levels change during projection. The balance principle and Hanke–Raus rule are modified by incorporating the error estimates of the projection noise level. We demonstrate the convergence rate of these two modified parameter choice rules through rigorous proof.
In addition, we find that the error between the approximate solution and the exact solution improves as the noise frequency increases. Finally, numerical experiments are provided to illustrate the theoretical findings presented in this paper.
Leo Strauss and Edith Stein in the Grip of the Theopolitical
Authors: Lévy Antoine 
Published: January 2024

Abstract
What connection with institutional religion ought modern political states promote? As they developed their political thinking in the early years of the Weimar Republic, Leo Strauss and Edith Stein came up with opposite answers to this question. While Strauss discerned in Carl Schmitt’s maximalist concept of the theopolitical a possible remedy against the flaws of liberal democracy, Stein ascribed democracy’s chance of survival to a renewed distinction between the political and religious spheres. Here, Strauss can be viewed as an heir to the ancient and medieval Jewish understanding of the ideal state, whereas Stein appears rooted in the critical legacy of the German Haskalah. At a fundamental level, the contrast between the two thinkers has to do with a difference in their respective philosophical epistemé. While Strauss, walking in the footsteps of Heidegger, thinks in terms of Geschichlichkeit (“historiality”), Stein applies a phenomenological method based on the intuition of essences and very much indebted to Adolph Reinach’s philosophy of law. That Stein's essentialism succeeds where the 'historial' thinking of the young Strauss fails; that is, in diagnosing the nature of the political threat that would soon engulf European Jewry, is the main conclusion of the present paper.

Abstract
We propose a programmable topological metasurface to integrate intelligent modulations of spatial and surface waves. A general design method is presented to design the programmable metasurface elements with PIN diodes. The surface waves can be controlled to propagate along the topological domain-wall interface by programming the C3-symmetry elements, while the spatial waves are modulated by the patterns of C6-symmetry elements. By independently controlling the bias voltages of meta-elements, the programmable topological metasurface can generate different coding patterns with distinct combinations of C3- and C6-symmetries in real time, respectively achieving the dynamical manipulation of the surface- and spatial-wave by using distinct element states in a time-division manner. To validate the modulation performance, we perform both near- and far-field tests with different coding patterns. Experimental results demonstrate good agreement with numerical simulations, thereby showcasing the flexible manipulations of surface waves and spatial waves by the topological metasurface. The proposed metasurface opens up new possibilities for multifunctional metadevices, which hold great potentials for future wireless communications and smart sensing systems.

Published: January 2024

Abstract
Fabry–Pérot (F–P) cavity and metal hole array are classic photonic devices. Integrating F–P cavity with holey metal typically enhances interfacial reflection and dampens wave transmission. In this work, a hybrid bound surface state is found within rectangular metal holes on a silicon substrate by merging an extraordinary optical transmission (EOT) mode and a high-order F–P cavity mode both spatially and spectrally. Transmission, Q-factor, and bandwidth can be enhanced significantly with respect to the classical EOT and F–P interference by simply sweeping the cavity length. This state can provide EOT properties and ten times broader EOT bandwidth well below the effective plasma frequency of the periodic metal holes, where the metal holes typically show evanescent properties and do not support EOT in theory. Furthermore, a large modulation range of 25 % and 39 % is demonstrated with various graphene patterns for the transmittance of this hybrid state at 500 and 582 GHz, respectively.
Penetration and spreading of graphene oxide ink in rice paper enabling its unique expressiveness in Chinese paintings
Authors: Liu Ximei , Teng Cheng , Li Jianlin 
Published: January 2024

Abstract
In Chinese paintings, the marriage of rice paper and ink is the soul of this art. Ink possesses a highly distinctive “color” expressiveness. By employing ink, various shades of black and diverse color effects can be portrayed, making the image more rich, vibrant, and three-dimensional on a rice paper. However, when used in traditional ink wash painting, the flow and penetration of conventional ink is difficult to control, and its carbon black particles make it a challenge to achieve multiple transparent gradients. Considering the water solubility and two-dimensional nanostructure of graphene oxide (GO), the authors of this paper has developed and proposed the use of water-based GO ink for Chinese ink wash painting, aiming to endow it with new aesthetic forms and unique expressive potentials.

Published: January 2024

Abstract
In this study, vibrations of stepped nanobeams were investigated according to Eringen’s nonlocal elasticity theory. Multi-time scale method, which is one of the perturbation methods, has been applied to solve dimensionless state equations. The solution is considered in two steps. First-order terms obtained from the perturbation expansion formed the linear problem in the first step. In the second step, the solution of the second order of the perturbation expansion was made and nonlinear terms emerged as corrections to the linear problem from this solution. The main issue that the study wants to emphasize is the examination of the mechanical effects of the steps, which are discontinuities encountered at the nanoscale, on the system. For this purpose, while the findings of the research were obtained, various nonlocal parameter values were obtained to capture the nano-scale effect, and frequency-response and nonlinear frequency-amplitude curves corresponding to the 1st Mode values of the beam for different step ratios and step locations were obtained to capture the step effect. One of the important features of the nonlinear system is the formation of internal resonance between the modes of the system. How this situation affects the characteristics of the system has also been examined and results have been given by graphs. The obtained data show that taking into account the nanoscale step is essential for the accuracy and sensitivity of many nanostructures such as sensors, actuators, biostructures, switches, etc. that are likely to be produced at the nanoscale in practice.

For years, Moringa oleifera has been known for possessing wound-healing properties. This study aimed to investigate the effect of two extracts: aqueous extract (AE) and ethanolic extract (EE) of Moringa oleifera leaves planted at two regions (Mssisi and Lamta) in Morocco for their anti-inflammatory and healing properties, for which mice were used as a biological model. Inflammation was monitored by assessing forepaw volume of mice, measured at 0 min, 1 h, 3 h, and 5 h, after its induction by carrageenan. Hind paw of mice were treated with extracts of M. oleifera, at a dose of 50 mg/kg, obtained from Mssisi region. This resulted in reduction of edema by 99.2% with EE and by 91.8% with AE, compared to controls and the phenolic extract of M. oleifera planted at Lamta region. Regarding healing of burns induced on rat’s dorsal region; results showed that application of Moringa-based ointment for 14 days, at a dose of 50 mg/kg on wounds, resulted in total healing, compared to controls (negative control: more than 22 days, and positive control: 22 days). M. oleifera extracts resulted in nearly complete tissue repair of 98.26% and 95.34% with EE and AE, respectively.

Authors: Nesterov S. P. 
Published: January 2024

On the occasion of the 60th anniversary of the first excavations at Poltse IThe study addresses the spatial arrangement of features at Poltse I—a Poltse culture settlement near the village of Kukelevo. An analysis of past scholarship reveals the sources of the modern understanding of the geographic and topographic location of the site and of its present condition. Although Poltse I and Poltse II, which is located nearby, were damaged by plowing in 1968, it is possible to continue excavations and obtain new information. On the basis of published materials, field plans in the archives, and artifacts at the SB RAS Institute of Archaeology and Ethnography, the first complete plan of excavations at Poltse I has been prepared, showing the arrangement of dwellings. Certain features of their design are described. Ceramic vessels found in each of the ten dwellings are listed. The vessels were placed along the perimeter of the interior, leaving free space around the central hearth and a passage to the exit. Most were concentrated in six dwellings. Only a few of them were used in everyday life, while most could have been destined for trade and barter. The abundance of ceramics (965 specimens and numerous separate fragments) makes Poltse I a key source for information on pottery manufacture, subsistence, and cultural ties. So far, it is impossible to say whether the vessels were manufactured in situ or imported.

Delegitimation of Komnas Perempuan's Discourse on Sexual Violence in the Ferdy's Sambo Case
Authors: Sholikhah Nur Imroatus 
Published: January 2024

Artikel ini melihat fenomena "hujatan" warganet atas pernyataan Komnas Perempuan tentang dugaan kekerasan seksual yang dialami istri Ferdy Sambo sebagai bentuk delegitimasi melalui wacana. Hal ini mengacu pada konsep legitimasi sebagai praktif diskursif yang memungkinkan mengalami delegitimasi melalui mekanisme opisisi. Delegitimasi dilakukan melalui tiga komponen pembentuk legitimasi wacana antara lain aspek otoritas, rasionalitas dan simbolik. Metode penelitian adalah studi kasus data postingan warganet di Twitter terkait Komnas Perempuan menggunakan alat esktrasi big data media sosial Intelligent Socio Analytic (ISA) sepanjang 1-10 September 2022. Hasil penelitian menunjukan delegitimasi wacana pada dimensi otoritas dilakukan dengan memposisikan Komnas Perempuan mendukung narasi Polisi. Pada dimensi rasionalitas, wacana Komnas Perempuan disebut melindungi pelaku pembunuhan dan tidak berpihak pada keluarga korban. Sementara, pada dimensi simbolik yakni dengan menyebut Komnas Perempuan sama dengan lembaga lain yang lemah menghadapi kekuasaan dan bisa disuap. Di era digital, deligitimasi wacana dapat menjadi bagian dari penguatan maupun pelemahan otoritas digital publik.

Modelling Infant Mortality Rate using Time Series Models
Authors: Ogundunmade Tayo P. , Daniel Akintola O. , M. Awwal Abdulazeez 
Published: January 2024

The world’s main indicator of children’s health and general development is the infant mortality rate for infant under the age of five. Infant mortality is the term used to describe the death of a child before their first birthday. The infant mortality rate (IMR), which is the number of deaths of infants under one year of age per 1,000 live births, can be used to describe the prevalence of infant mortality in a population. Comparing the death rate of children under the age of five is the child mortality rate, commonly referred to as the under-five mortality rate. Nigeria, one of the nations with a high under-five mortality rate of 117 per 1,000 live births in 2019, is among those nations. The nation is among the top five nations with the highest mortality rate for children under five in 2019. This study aims to model infant mortality(Live birth and Still birth) rate using time series models and to predict the mortality rate using these models. Adeoyo Maternity Hospital Yemetu in Ibadan provided the data for this study. The data set is a monthly data and also a secondary data span for a period of 12 years (2009 to 2020). The time plot showed visual inspection and non-stationarity. Differencing was done and the unit root test performed for the purpose of comparison thereafter. Augmented-Dickey Fuller test and Phillip Perron unit root test was further tested for the establishment of stationarity in order to the main objectives. Three time series methods are the Autoregressive Integrated Moving Average Model(ARIMA), Exponential Smoothing and the Holt-Winters Method were used to model and predict the infant mortality rate data. The result shows that ARIMA order=c(0,0,1) with zero (0) mean for stillbirth and ARIMA order=c(1,0, 2) for live birth with the smallest AIC = (9.102 and 13.991). Akaike Information Criterion(AIC) values of (9.289, 14.139) and (9.102, 13.991) for live birth and still birth, respectively, were derived by exponential smoothing and Holtwinters technique. This means that Holtwinters' technique, which yielded the lowest AIC when compared to ARIMA and exponential smoothing, is the most accurate predictor of both stillbirth and live birth data. Given the high mortality rate for children under the age of five, it is crucial for the government to place more of an emphasis on health issues and to solve the problems plaguing Nigeria's child health care system.
