Numerical solution of a malignant invasion model using some finite difference methods
Authors: Appadu Appanah Rao , Waal Gysbert Nicolaas de 
Published: July 2023

Abstract
In this article, one standard and four nonstandard finite difference methods are used to solve a cross-diffusion malignant invasion model. The model consists of a system of nonlinear coupled partial differential equations (PDEs) subject to specified initial and boundary conditions, and no exact solution is known for this problem. It is difficult to obtain theoretically the stability region of the classical finite difference scheme to solve the set of nonlinear coupled PDEs, this is one of the challenges of this class of method in this work. Three nonstandard methods abbreviated as NSFD1, NSFD2, and NSFD3 are considered from the study of Chapwanya et al., and these methods have been constructed by the use of a more general function replacing the denominator of the discrete derivative and nonlocal approximations of nonlocal terms. It is shown that NSFD1, which preserves positivity when used to solve classical reaction-diffusion equations, does not inherit this property when used for the cross-diffusion system of PDEs. NSFD2 and NSFD3 are obtained by appropriate modifications of NSFD1. NSFD2 is positivity-preserving when the functional relationship

holds, while NSFD3 is unconditionally dynamically consistent with respect to positivity. First, we show that NSFD2 and NSFD3 are not consistent methods. Second, we tried to modify NSFD2 in order to make it consistent but we were not successful. Third, we extend NSFD3 so that it becomes consistent and still preserves positivity. We denote the extended version of NSFD3 as NSFD5. Finally, we compute the numerical rate of convergence in time for NSFD5 and show that it is close to the theoretical value. NSFD5 is consistent under certain conditions on the step sizes and is unconditionally positivity-preserving.

Abstract

Objectives
Pelvic floor disorders are frequently caused by an organ prolapse involving multiple pelvic floor compartments. In such cases, a multidisciplinary strategy for diagnostic work-up and therapy is required.

Methods
All patients who underwent transabdominal rectopexy/resection rectopexy alone or in combination with simultaneous gynecological pelvic floor reconstruction at our institution between 01/2006 and 12/2021 were included in this retrospective study. The study aimed to evaluate the functional outcome and postoperative complications.

Results
Two hundred and eighty seven patients were assigned to one of the following groups: PG1 – patient group one: after resection rectopexy (n=141); PG2 – after ventral rectopexy (n=8); PG3 – after combined resection rectopexy and sacro (cervico)colpopexy (n=62); PG4 – after combined resection rectopexy and trans-vaginal pelvic floor repair (n=76). The duration of follow-up was 14 months for PG1 (median, IQR 37 months), 11 months for PG2 (mean, SD 9 months), 7 months for PG 3 (median, IQR 33 months), and 12 months for PG 4 (median, IQR 51 Months). The surgical procedure resulted in improvement of symptoms related to obstructed defecation in 56.4 % (22/39) of the patients in PG1, 25 % in PG2 (1/4), 62.5 % (20/32) in PG3, and 71.8 % (28/39) in PG4. “De novo” constipation was reported by 2.4 % (2/141) of patients from PG1. Improvement in fecal incontinence symptoms was reported by 69 % (40/58) of patients in PG1, 100 % in PG2 (2/2), 93.1 % (27/29) in PG3, and 87.2 % (34/39) in PG4. The recurrence rate for external rectal prolapse was 7.1 % in PG1, 50 % in PG2 (1/2), 2.7 % in PG3, and 6.3 % in PG4. A significant difference in terms of severe morbidity (grade ≥ IIIb) and mortality could not be determined between the non-interdisciplinary (PG1 with PG2) and interdisciplinary surgery (PG3 with PG4) (p=0.88, p=0.499).

Conclusions
Based on our results, we can assume that combined surgery is as feasible as rectal surgery alone. In our study, combined interventions were effective and not associated with an increased risk of postoperative complications.

Multi-height metasurface for wavefront manipulation fabricated by direct laser writing lithography
Authors: Ye Fan , Pivnenko Mike , Huang Huiyu , Chang Xin , Robinson Lee , Zheng Youdou , Shi Yi , Chu Daping 
Published: July 2023

Abstract
We introduce two types of dielectric metasurfaces, consisting of 3 × 3 regions, which manipulate wavefront by different feature heights. Both polarization-dependent and polarization-independent metasurfaces are realized for phase depth of 0 ∼ 2π at 1550 nm, with considerable average transmittance of 80.1 and 85.1 %, respectively. The phase modulation capability can be extended over a broadband range of 1460.1–1618.0 nm for optical communications, by carefully designing nanofeature sizes. Moreover, the entire metasurfaces with nanofeatures of varying heights can be fabricated in a single process by using direct laser writing with high-precision, which is beneficial for mass production and promising in developing efficient and ultracompact devices.
Thickness insensitive nanocavities for 2D heterostructures using photonic molecules
Authors: Ji Peirui , Qian Chenjiang , Finley Jonathan J. , Yang Shuming 
Published: July 2023

Abstract
Two-dimensional (2D) heterostructures integrated into nanophotonic cavities have emerged as a promising approach towards novel photonic and opto-electronic devices. However, the thickness of the 2D heterostructure has a strong influence on the resonance frequency of the nanocavity. For a single cavity, the resonance frequency shifts approximately linearly with the thickness. Here, we propose to use the inherent non-linearity of the mode coupling to render the cavity mode insensitive to the thickness of the 2D heterostructure. Based on the coupled mode theory, we reveal that this goal can be achieved using either a homoatomic molecule with a filtered coupling or heteroatomic molecules. We perform numerical simulations to further demonstrate the robustness of the eigenfrequency in the proposed photonic molecules. Our results render nanophotonic structures insensitive to the thickness of 2D materials, thus owing appealing potential in energy- or detuning-sensitive applications such as cavity quantum electrodynamics.

Panji Jayalengkara Angreni which is one part of the Panji Angreni variety has a close relationship with oral and written traditions. With the existence of multi-layered traditions and a very broad corpus, it is necessary to describe the distribution of traditions, especially in the realm of Javanese culture in Surakarta. Thus, this study aims to reveal the relationship between the oral and written traditions of Panji Jayalengkara Angreni. In revealing this relationship, it is necessary to understand that the manuscript and oral traditions are a unity as a basic foundation. This study uses a qualitative method and is based on a research method that combines manuscript writing traditions and artistic traditions, as was done by Vickers on the Malat text. As a limitation, the search for the corpus of written and oral literature is only focused on the Surakarta tradition, especially those related to oral literature in performing art. The text of Panji Angreni appears in the literary tradition of the northern coast of Java which developed with additions and recompositions. Panji Angreni Palembang as the oldest text shows the form of Panji Angreni which is still much influenced by Old Javanese literature. Panji Angreni developed by being combined with the story of Jayalengkara in the Surakarta era.The relationship between Panji Jayalengkara Angreni's written text and oral text is evident in the realm of wayang, dance, and musical performances. This relationship is not just a one-way relationship, but a reciprocal relationship between written and oral traditions.

Javanese is one of the unique regional languages ​​because it has speech levels which are shown through spoken language in daily life conversations, while forms of written language are usually applied through Javanese literary works. This article aims to analyze the form and factors that cause the occurrence of speech levels used by the characters in cêrkak that represent people's lives. This study was studied using a qualitative descriptive method and analyzed using a sociolinguistic approach in the speech level study. The research data is sourced from documents of speech level that originating from dialogues between characters in five cêrkak on the Jawasastra web page. Research subjects were selected through purposive sampling, while data was collected through document analysis. The data were analyzed with an interactive analysis model through data collection, data reduction, data presentation, and drawing conclusions. In this study, four variations of speech levels were found, including: 12 data of ngoko lugu, 3 data of ngoko alus, 1 data of krama lugu, and 9 data of krama alus. The factors behind the use of each level of speech within the scope of Javanese society are due to differences in levels of education, economy, age, position, familiarity, and heredity.

Published: July 2023

Protection of oral literature from extinction can be done by an inventory program in the form of transferring texts from oral tradition to written literature. The folklore (legend) of Nyai Ageng Bakaran folklore originates from a village in the Juwana District, Pati Regency, Central Java. This story underlies traditions still carried out by the people of Bakaran Wetan village. This study aims to describe the structure and function of the legend of Nyai Ageng Bakaran. The oral literary tradition will recede with the reduction of actors and supporters of literary activities in society. Folklore inventory is an effort to document oral literature in the context of conservation and protection of folklore sources so that they can be maintained for the future. Data collection techniques use interview techniques and literature studies. Data analysis was carried out by collecting information with triangulation techniques from 3 speakers, voice recordings, and narrative texts in the form of notes from research results and data analysis techniques with the theory of structure and folkloric functions. The results of the research on the structure and function of the legend of Nyai Ageng Bakaran are intrinsic elements in the form of plots that contain the narrative units of this story, characters and characterizations, and the story's setting. Then, the function of legend is in the form of a description of 4 folkloric processes taken from William Bascom's theory, namely function as a projection system, as a tool for attestation of institutions and cultural institutions, as a child education tool (pedagogical device), as a tool of coercion and supervision so that its collective members will always obey the norms of society.

Language has a very important role in life. Through language, humans can interact with each other both orally and in writing which aims to convey information. The form of interaction is not only in the form of direct communication but can also be in the form of indirect communication. As is the case with the interaction of a film which has the aim of conveying a message to its audience. Of the many films on YouTube, one type of film that is quite interesting is a regional language film, one of which is a Javanese language film. Javanese-language films also have a contribution in an introduction to the culture of a region. One of the newest films that uses Javanese and has language variations is the film Lara Ati by Bayu Skak. This research uses a theoretical approach in the form of a sociolinguistic approach and a methodological approach in the form of a qualitative descriptive approach. The data collection technique used is the observing and noting technique. The analysis technique uses a qualitative descriptive technique. The source of the data for this study is the Lara Ati Drama Workshop episodes 1 to 5 which are sourced from YouTube videos. The results of this study are the use of language that appears in the drama workshops in the form of Javanese, a variety of ngoko, krama and also a mix of languages. In addition, the characteristics that appear in the drama scene are language variations, namely dialect, speech level, code-switching and splitting. Based on the results of this study, there were errors in the use of the Javanese language based on the context. In addition, the characteristic forms that emerged were language variations including the Suroboyoan dialect and the ngapak dialect, the speech level of the Javanese language, the variety of ngoko lugu, ngoko alus, and krama lugu, krama alus, code mixing. -code switching, and splitting.

Published: July 2023

Mantra is a distinctive choice of words, the meaning of which can only be known through in-depth cultural reading based on the culture in which the mantra lives. This study aims to describe the structure and function of the mantra language in Javanese society. The research method uses a qualitative descriptive approach. Sources of research data are Javanese mantras collected by purposive sampling. Data were analyzed by semantic analysis. The validity of the data used is semantic validity with semantic analysis techniques. The results of research on Javanese mantras are as follows: 1) the structure of the spell consists of a title, opening, suggestion, purpose, and conclusion of the spell; 2) the function of the mantra based on the user's purpose is generally divided into individual functions and social functions. The cultural aspects surrounding the spell have certain functions which are believed to have magical powers by the people. In Javanese culture, mantras have a special position in the religious system and public beliefs. The community also believes that each mantra recited has a different function according to the contents of the mantra recited by the speaker.

Ranah Sumber Binatang dalam Panyandra: Menjadi Cantik ala Orang Jawa
Authors: Kurnia Ermi Dyah , , Suhandano , , Hendrokumoro 
Published: July 2023

Panyandra is a form of expression in Javanese which is used to praise someone's beauty or beauty. Panyandra in Javanese society is usually to praise the bride (nyandra manten). Panyandra is a form of metaphor because it has metaphorical components such as the target domain, the source realm and the mapping between the target realm and the source realm. An interesting thing to study is the use of the source domain in panyandra. If panyandra is used to praise the beauty, however, the source realm used as a comparison looks far from beauty. An example is the use of the beast's source realm. Panyandra as a form of metaphor in Javanese can be used as an expression of the human conceptual system in thinking. This is based on the understanding that metaphor can be a reflection of the cognition and culture of a speech community. Thus, this study aims to describe the use of the animal source domain in panyandra as a form of cognitive process to understand the concept of female beauty according to the Javanese view. This study used descriptive qualitative method. Data sources are limited to pannyandra. Data collection was carried out using the observing and noting method so that the panyandra was collected in the form of sentences. Next, the data is analyzed to classify panyandra as a metaphor based on the animal source domain and the mapping pattern of the beauty metaphor using the animal source domain. The theoretical framework used as the basis for thinking in this study is a conceptual metaphor; the relationship between language, culture and thought; and analysis of meaning components. The results obtained are that there are various types of animals that are used as source domains, namely insects, wild animals, birds, and reptiles. There is a pattern of mapping relationships between the target domain and the source domain, namely through the properties of both of them are defined socio-culturally, then the two domains are mapped.

This study aimed to reveal the impact of financial risk management on the performance of Jordanian insurance companies. The study sample consisted of (21) Jordanian insurance companies, all of whom were selected from the Amman Stock Exchange for the period (2009-2018). The study followed descriptive and analytical approach. Multiple regression analysis was also applied to measure the impact of various investments (financial investments, other investments and reinsurance) on the financial performance as measured by the return on equity. - ROE, in addition to measuring the standard deviation of returns for each type of investment to identify the role of macro risk on insurance companies` financial performance. Empirically the results showed that there a statistically significant impact of financial investments, other investments and reinsurance on the financial performance of insurance companies, where other investments reflected the highest degree of significant impact (3.707), and the least in terms of the degree of significant influence was for financial investments (B = 0.205). The results also showed that the returns of financial investments are characterized by a very high degree of variance in term of returns. The study recommended the need to increase and diversify their investments especially in real estate and certificate of deposit diversifying also, to plan effectively to face high-level risks according to a specific and effective strategy approved by specialized experts in the field of risk management.
