Authors: Chen Wenxiong , Hu Yeyao , Ma Lingwei 
Published: March 2024

Abstract
In this paper, we summarize some of the recent developments in the area of fractional elliptic and parabolic equations with focus on how to apply the sliding method and the method of moving planes to obtain qualitative properties of solutions. We will compare the two methods and point out the pros and cons of each. We will demonstrate how to modify the ideas and techniques in studying fractional elliptic equations and then to employ them to investigate fractional parabolic problems. Besides deriving monotonicity of solutions, some other applications of the sliding method will be illustrated. These results have more or less appeared in a series of previous literatures, in which the ideas were usually submerged in detailed calculations. What we are trying to do here is to single out these ideas and illuminate the inner connections among them by using figures and intuitive languages, so that the readers can see the whole picture and quickly grasp the essence of these useful methods and will be able to apply them to solve a variety of other fractional elliptic and parabolic problems.

Abstract
To study the impact response and compression-after-impact (CAI) behavior of perforated sandwich panels comprised of foam core and glass fiber-reinforced epoxy hybrid facesheets, the hole diameter of specimens is changed in the fabrication via vacuum-assisted resin infusion. Furthermore, low-velocity-impact tests with various impact distances between the impact point and hole are carried out. With the help of the digital image correlation technique, CAI testing is conducted, and the strain evolution of specimens is monitored carefully. The mechanical response history, damage morphology, and compressive process are discussed in detail. The results show that the impact and CAI performance of specimens are weakened because of open holes. Compared with the non-perforated specimen, the maximum force of the specimen with a 6-mm hole and the 5-mm impact distance decreases by 41.21%, and its maximum displacement increases by 38.60%. During the CAI process, in comparison with the impact damage, more significant stress concentration and buckling around the hole are found.
On the unified representation of continuity and discontinuity and its neurocognitive grounding
Authors: Nirupama Ratna , Mondal Prakash 
Published: March 2024

Abstract
Discontinuity in natural language is characterized by the linear disruption of a continuous string of linguistic expressions forming a constituent. While dependency relations in Dependency Grammar (DG) can capture discontinuity well, phrase-structure-based approaches such as Phrase Structure Grammar (PSG) face difficulty in accommodating discontinuity. Categorial Grammar (CG) has correspondences with PSG, although it can handle discontinuity, if equipped with wrapping operations. Given the existing literature on discontinuity in natural language, it appears that constituency relations of PSG, dependency relations of DG and functor-argument relations of CG are distinct and independent. Here, we argue for a unified representation achieved by taking into account fundamental representational principles of PSG, DG and CG. For simplicity, we show this by considering an embedded clause from Wan, spoken in Ivory Coast, as an illustrative case. The paper then attempts to explain, based on available empirical pieces of evidence, the plausible connections between the unified representation and the neurocognitive representation of continuity and discontinuity in natural language.
Analysis of metallurgical defects in enamel steel castings
Authors: Rui Qixuan , Huang Zijian , Li Yingjiang , Hu Xiaoguang 
Published: March 2024

Abstract
The relevant experiments and studies were conducted to address the metallurgical defects such as subcutaneous bubbles and slag inclusions occurring during the enamel steel continuous casting process. According to the high-temperature experimental results, calculations were made to determine the changes in viscosity and tension due to the steel reaction with the slag. Based on the experimental findings, there was a notable variation in the content of SiO2 and Al2O3 in the slag before and after the reaction. The concentration of the element Al in the steel melt significantly decreased, whereas the concentration of Ti showed a minimal change. These observations indicate that the reduction of SiO2 at the slag–steel interface is predominantly attributed to the role of Al. The calculation results showed that at 300 s of reaction time, the viscosity rapidly increased from 0.108 to 0.133 Pa·s and then slowly increased to 0.155 Pa·s; The interfacial tension rapidly decreased from its initial value of 1,380 mJ·m−2 to a minimum of 1,320 mJ·m−2, and it then slowly increased to an equilibrium state. Therefore, the main cause of the occurrence of porosity defects in the enamel steel continuous casting process is the reduction of interfacial tension between slag, steel, and gas caused by the reaction between the slag and steel, as well as the foaming of the slag.
Artificial intelligence for COVID-19 spread modeling
Authors: Krivorotko Olga , Kabanikhin Sergey 
Published: March 2024

Abstract
This paper presents classification and analysis of the mathematical models of the spread of COVID-19 in different groups of population such as family, school, office (3–100 people), town (100–5000 people), city, region (0.5–15 million people), country, continent, and the world.
The classification covers major types of models (time-series, differential, imitation ones, neural networks models and their combinations).
The time-series models are based on analysis of time series using filtration, regression and network methods.
The differential models are those derived from systems of ordinary and stochastic differential equations as well as partial differential equations.
The imitation models include cellular automata and agent-based models.
The fourth group in the classification consists of combinations of nonlinear Markov chains and optimal control theory, derived by methods of the mean-field game theory.
COVID-19 is a novel and complicated disease, and the parameters of most models are, as a rule, unknown and estimated by solving inverse problems.
The paper contains an analysis of major algorithms of solving inverse problems: stochastic optimization, nature-inspired algorithms (genetic, differential evolution, particle swarm, etc.), assimilation methods, big-data analysis, and machine learning.
Form Copy, Agree and Clitics
Authors: Roberts Ian 
Published: March 2024

Abstract
Here it is proposed that Form Copy (Chomsky, Noam, T. Daniel Seely, Robert C. Berwick, Sandiway Fong, M. A. C. Huybregts, Hisatsugu Kitahara, Andrew McInnerney, Yushi Sugimoto. 2023. Merge and the strong minimalist thesis. In Cambridge elements. Cambridge University Press), applied to features, can derive a very simple form of Agree without the need for the distinction between interpretable and uninterpretable features or the Activity Condition. Furthermore, since Roberts (Roberts, Ian. 2010. Agreement and head movement: Clitics and defective goals. Cambridge, MA: MIT Press) derives head-movement from Agree, Form Copy can be similarly extended in such a way as to derive the effects of head-movement. This conclusion holds independently of whether head-movement is a purely morphophonological operation or whether there are narrow-syntactic cases. It is also shown how an account of cliticisation, both proclisis and enclisis, can be derived, updating the proposals in Roberts (Roberts, Ian. 2010. Agreement and head movement: Clitics and defective goals. Cambridge, MA: MIT Press) in terms of Form Copy.
Rekonstruktion einer Vortragssituation Eduard Liesegangs Lichtbildserie „Unsere Kolonien“
Authors: Mihr Maximilian August am 
Published: March 2024

AbstractZwischen 2004 und 2011 hat das Filmmuseum der Landeshauptstadt Düsseldorf schrittweise das gesamte Archiv des Unternehmens Eduard (im Folgenden kurz Ed.) Liesegang oHG, dem seit 1854 bestehenden führenden deutschen Hersteller für Projektionsgeräte und -zubehör im 20. Jahrhundert, übernommen. Zusätzlich wurden Dia- und Lichtbildserien der Firma als Schenkung erworben. Liesegang hatte nicht nur Diapositive, sondern auch entsprechende Begleittexte im Angebot und das Unternehmen stellte sogar Referenten für verschiedene Projektionsreihen. Der heute kaum noch praktizierte Diavortrag spielte eine wichtige Rolle im Unternehmenskonzept. In diesem Kontext ist die Lichtbildserie 645 mit dem Titel „Unsere Kolonien“ aus dem Jahr 1912 besonders bemerkenswert. Es ist anzunehmen, dass die kolorierten Glasdiapositive in Vortragssituationen der vielen lokalen Niederlassungen der Kolonialverwaltung des Kaiserreichs zum Einsatz kamen, beispielsweise der Deutschen Kolonialgesellschaft oder des Deutschen Kolonialvereins.

Painful differences between different pain scale assessments: The outcome of assessed pain is a matter of the choices of scale and statistics
Authors: Svensson Elisabeth , Lund Iréne 
Published: March 2024

Abstract

Objectives
Perceived pain is a multi-factorial subjective variable, commonly measured by numeric rating scales, verbal descriptive scales (VDS), or by a position on an analogue line (VAS). A major question is whether an individual’s VAS and VDS pain assessments, on the same occasion, could be comparable. The aim was to compare continuous and discretized VAS pain data with verbal descriptive pain datasets from the Oswestry Disability Index (ODI) and the European Quality of Life Scale (EQ-5D) in paired pain datasets.

Methods
The measurement level of data from any type of scale assessments is ordinal, having rank-invariant properties only. Non-parametric statistical methods were used. Two ways of discretizing the VAS-line to VAS-intervals to fit the number of the comparing VDS-categories were used: the commonly used (equidistant VAS,VDS)-pairs and the (unbiased VAS,VDS)-pairs of pain data. The comparability of the (VAS,VDS)-pairs of data of perceived pain was studied by the bivariate ranking approach. Hence, each pair will be regarded as ordered, disordered, or tied with respect to the other pairs of data. The percentage agreement, PA, the measures of disorder, D, and of order consistency, MA, were calculated. Total interchangeability requires PA = 1 and MA = 1.

Results
The wide range of overlapping of (VAS,VDS)-pairs indicated that the continuous VAS data were not comparable to any of the VDS pain datasets. The percentage of agreement, PA; in the (equidistant VAS,ODI) and (equidistant VAS, EQ-5D) pairs were 38 and 49%, and the order consistency, MA, was 0.70 and 0.80, respectively. Corresponding results for the (unbiased VAS,VDS)-pairs of pain data were PA: 54 and 100%, and MA: 0.77 and 1.0.

Conclusion
Our results confirmed that perceived pain is the individual’s subjective experience, and possible scale-interchangeability is only study-specific. The pain experience is not possible to be measured univocally, but is possible for the individual to rate on a scale.

Abstract
The rising concern about the environmental pollution, particularly due to the setup of more industrial sectors has grabbed the attention of scientists and researchers. Many textile businesses emit Malachite Green and Methylene Blue (MG and MB) into the atmosphere, posing serious health risks. In this study, a copper metal-organic framework doped with iron nanoparticles (Cu-MOF@Fe3O4) was synthesized utilizing the slow evaporation approach, commencing with cuprous chloride and 2-mercaptobenzimidazole in a 1:2 ratio. Cu-MOF@Fe3O4 was characterized using a variety of techniques, including FTIR, SEM, and DRS analysis. The SEM analysis showed a rough and uneven morphology for the Cu-based MOFs. The XRD analysis confirmed the crystallinity of the products. The average crystallite size for Cu-MOF, Fe3O4 nanoparticles and Cu-MOF@Fe3O4 were found to be 0.22, 1.00, and 1.00 nm. While the surface area of Cu-MOF was found to be 213.192 m2g−1 while in Cu-MOF@Fe3O4 it shows an increase, i.e., 218.268 m2g−1 as calculated through the iodometric method. A series of experiments were conducted to assess the surface area, chemical oxygen demand (COD), limit of detection (LOD) (0.065559, 0.0136), limit of quantification (LOQ) (0.198662, 0.041312), point of zero charge (PZC) (5.2), pH levels (6, 7), contact times (10, 25 min), photocatalyst dosages (0.3, 0.05 g), dye concentrations (2, 10 µg/mL), and temperature effects (50°, 90°) on the adsorption and photocatalytic degradation of MG and MB, respectively. Photodegradation of both dyes followed pseudo-second order kinetics with R
2 values of 0.9833 (MG) and 0.8875 (MB). The adsorption isotherms (Freundlich and Langmuir) for MG and MB dye were analyzed and the experimental data holds a good correlation with Freundlich isotherm. The sample application of Cu-MOF@Fe3O4 as a photocatalyst, has high efficiency,  % photocatalysis (96.9 % MG, 99.4 % MB) with reusability (95–100 %) upto 10 cycles to photodegrade MG and MB dye in wastewater. To the best of our knowledge, this is the first report on the deployment of copper-based MOFs-doped with magnetite for the photocatalytic degradation of MG and MB dyes.

Era transformasi digital 4.0 ini marak penggunaan citraan berbasis digital untuk berbagai kebutuhan, dari jualan hingga hiburan. Metaverse memiliki peluang besar di Indonesia karena dapat digunakan di berbagai bidang seperti pariwisata, pendidikan, kesejahteraan sosial dan perdagangan di Indonesia. Namun demikian, belum banyak berkembang pembahasan mengenai kualitas citra yang standar untuk kebutuhan sinematografi. Citra yang dimaksud adalah suatu representasi (gambaran), kemiripan atau imitasi dari suatu objek. Citra sebagai keluaran suatu sistem perekaman data dapat bersifat optik berupa foto, bersifat analog berupa sinyal-sinyal video seperti gambaran pada monitor televisi, atau bersifat digital yang dapat langsung disimpan pada suatu media penyimpanan. Meskipun sebuah citra kaya akan informasi, namun sering kali citra yang dimiliki mengalami penurunan mutu, misalnya mengandung cacat atau denois. Metode yang digunakan dalam sinematografi meliputi camera angle, continuity, cutting, dan composition. Hasil penelitian ini adalah Penggunaan aspek sinematografi terutama dalam karya animasi ataupun syuting mempunyai mood dan teknik pencahayaan yang sama dengan pengarahan pada media yang lain. Dalam pencahayaan film VR yang menggunakan metode pembuatannya menggunakan animasi tiga dimensi mempunyai treatment yang lebih menonjolkan kesan tekstur yang gelap dan low-key lighting
In this era of digital transformation 4.0, there is widespread use of digital-based imagery for various needs, from sales to entertainment. Metaverse has great opportunities in Indonesia because it can be used in various fields such as tourism, education, social welfare and trade in Indonesia. However, there has not been much discussion about standard image quality for cinematography needs. The image in question is a representation (picture), resemblance or imitation of an object. The image as the output of a data recording system can be optical in the form of photos, analog in the form of video signals such as images on a television monitor, or digital which can be directly stored on a storage medium. Even though an image is rich in information, the image that is owned often suffers a loss of quality, for example, contains defects or defects. The methods used in cinematography include camera angle, continuity, cutting, and composition. The result of this research is that the use of cinematographic aspects, especially in animation or filming works, has the same mood and lighting techniques as directed at other media. In VR film lighting, which uses a three-dimensional animation method, it has a treatment that emphasizes the impression of a dark texture and low-key lighting.
Sakit Rindu: Romanticization of Manthous's Songs in Commodification Practices by Dapur Musik Project
Authors: Andini Mustika , Dienaputra Reiza D. , Nugrahanto Widyo 
Published: March 2024

The phenomenon of music cover in new media is now increasingly mushrooming, especially in Indonesia. Dapur Musik Project, as a keroncong music group consisting of young people, also works on cover versions of Manthous's songs, who is considered a predecessor to them. Sakit Rindu is one of Dapur Musik Project content that is most popular with the audience, as evidenced by the acquisition of million viewers.
This research uses qualitative methods to analyze how Dapur Musik Project commodifies the songs composed by Manthous. In general, this research uses the framework of Adorno and Horkheimer (1944) which expresses the cultural industry theory, commodification theory put forward by Mosco (2009), and social practice theory or structural-constructive theory from Bourdieu's (1984) framework. The results of this research explain the commodification practices carried out by Dapur Musik Project in the realm of musicals and performances, as well as in the realm of packaging and marketing, with an attachment to industry and economic value. Dapur Musik Project also utilizes the symbolic power they have over relational relationships as the Manthous family in perpetuating commodification practices.
The various changes in form, composition, packaging and strategy carried out by Dapur Musik Project are not considered renewal, but only a form of romanticization of Manthous's songs. Dapur Musik Project is an example of how youth people try to mediate the standardization polemic in keroncong music with their own roles and methods. This research annunciating the keroncong music community about the urgency of commodification practices in the discourse on the preservation and development of keroncong music in the Indonesian music scene.
