Estimating the Morse index of free boundary minimal hypersurfaces through covering arguments
Authors: Cordero-Misteli Santiago , Franz Giada 
Published: January 2024

Abstract
Given a compact Riemannian manifold, of dimension between 3 and 7, with boundary, we adapt Song’s covering method to the free boundary case to show that the Morse index of a free boundary minimal hypersurface grows linearly with the sum of its Betti numbers, where the constant of growth depends on an upper bound on the area of the free boundary minimal hypersurface in question.

Knocking on Wood: Writing Boards in the Kassite Administration
Authors: Zimmermann Lynn-Salammbô 
Published: January 2024

AbstractThis article explores the emerging role of wooden wax-covered writing boards in Kassite administration, as indicated by their mentions in three letters and one cattle account from Kassite period Nippur. Even though the number of textual references is scarce, the use of wooden wax-covered writing boards is supported by the depictions on late Kassitekudurrumonuments. By incorporating perspectives from Middle Assyrian texts and Neo-Assyrian sealings, this study interprets references to writing board usage in Kassite letters, revealing their role in documenting conscripted workers and their rations. This interpretation finds support in evidence from the Ur III period, contemporary Emar, and the Neo-Babylonian period, collectively suggesting that writing boards were regarded as durable and highly reliable sources. The appearance of seal rings in Babylonia in 13th century BC allows for the hypothesis that wooden wax-covered writing boards could have been sealed in a similar fashion as is assumed for Neo-Assyrian writing boards containing lists of ERIN2.MEŠ troops of the king. Notably, the Kassite period letters indicate that writing boards were archived for minimum of 50 years and were checked to verify claims.
Thermal and electrical properties of photovoltaic cell with linear phenomenological heat transfer law
Authors: Li Jun , Chen Lingen 
Published: January 2024

Abstract
The thermal and electrical properties of photovoltaic cell (PVC) under linear phenomenological heat transfer law between it and the environment is studied through finite time thermodynamics and the volt-ampere characteristic equation. The properties of PVC are affected by heat transfer between PVC and environment. There are optimal solar radiation intensity and PVC output voltage (OV), which make the photoelectric conversion efficiency (PECE) of PVC reach the highest value. When OV and solar radiation intensity are 28.50 V and 700 W/m2, the maximum PECE is 0.156. There is also the best solar radiation intensity, which makes the open-circuit voltage (OCV) reach the maximum. When solar radiant intensity is 669 W/m2, the maximum OCV is 33.14 V. The values of power output and short-circuit current (SCC) are monotonically increasing with solar radiation intensity. Given solar radiation intensity, the power output and OV exhibit a parabolic shape. The operating temperature falls first and then grows with the OV. However, the change of operating temperature with OV is not much. Band gap is a decreasing function of operating temperature. This article can give theoretical support for the design and use of PVCs.

Effect of total heat input on coaxiality of rotor shaft in laser cladding
Authors: Guo Shirui , Yu Junhao , Cui Lujun , Cui Yinghao , Li Xiaolei , Chen Yongqian , Zheng Bo 
Published: January 2024

Abstract
The total heat input by the laser directly affects the temperature distribution of the rotor shaft during the cladding process, and then affects its coaxiality. This article uses ANSYS for numerical simulation to study the effect of laser heat input on the deformation of the rotor shaft during laser cladding process. Simulate and analyze the temperature and stress fields inside the rotor shaft using thermal coupling. The results show that by changing the pitch, axial cladding width and laser irradiation duration to change the laser induced total heat input, a more uniform temperature distribution can be generated in the rotor shaft. The increase of temperature distribution uniformity can reduce the deformation of rotor shaft during cladding. Using a cladding equipment, iron based customized alloy powder was coated on the 45 steel rotor shaft for cladding experiments. And the mechanical properties and coaxiality of the rotor shaft after cladding were measured. The results showed that the hardness and wear resistance of the cladding layer were significantly improved compared to the substrate, and the changes in coaxiality of the rotor shaft were consistent with the simulation results, with relatively small errors. It is of great significance for repairing damaged rotor shafts.
Low-loss hybrid germanium-on-zinc selenide waveguides in the longwave infrared
Authors: Ren Dingding , Dong Chao , Høvik Jens , Khan Md Istiak , Aksnes Astrid , Fimland Bjørn-Ove , Burghoff David 
Published: January 2024

Abstract
The longwave infrared (LWIR) range, which spans from 6 µm to 14 µm, is appealing for sensing due to strong molecular fingerprints in this range. However, the limited availability of low-loss materials that can provide higher-index waveguiding and lower-index cladding in the LWIR range presents challenges for integrated photonics. In this work, we introduce a low-loss germanium-on-zinc selenide (GOZ) platform that could serve as a versatile platform for nanophotonics in the LWIR. By bonding high-quality thin-film germanium (Ge) to a zinc selenide (ZnSe) substrate, we demonstrate transparency from 2 µm to 14 µm and optical losses of just 1 cm−1 at 7.8 µm. Our results demonstrate that hybrid photonic platforms could be invaluable for overcoming the losses of epitaxially grown materials and could enable a wide range of future quantum and nonlinear photonics.
Poly- and per-fluoroalkyl substances in water: Occurrence, analytical methodologies, and remediations strategies: A comprehensive review
Authors: Malatji Nompumelelo , Mpupa Anele , Nomngongo Philiswa Nosizo 
Published: January 2024

Abstract
Poly- and perfluoroalkyl substances (PFASs) are fluoro-organic compounds comprising thousands of anthropogenically produced chemicals with various industrial and consumer applications. This review compiles recent information on the sources, occurrence, and health effects of PFAS in aquatic environments. Secondly, as a primary requirement for assessing the PFAS concentration in water, this review systematically summarised the analytical methodologies (sample preparation and analytical detection techniques) for PFAS. Furthermore, health risks associated with PFAS in water are outlined. Finally, researchers worldwide have investigated the strategies for the remediation and elimination of PFAS from water. Previous studies have shown that PFASs are present in various water bodies with the highest concentration detected in Germany (94–4,385 ng·L−1 in river and drinking waters). The findings of this review further revealed that solid-phase extraction techniques were the most preferred for sample preparation compared to liquid–liquid extraction techniques. Solid-phase extraction technique improved the limit of detection and the limit of quantification of many analytical techniques to 0.010–1.15 and 0.030–4.00 ng·L−1, respectively. For PFAS remediation, the adsorption method and chemical oxidation using heat-activated persulfate and photochemical oxidation were the most used techniques. The most studied water matrices were drinking, river, groundwater, wastewater, and modelled ultra-pure water. The most used detection technique was found to be liquid chromatograph-tandem mass spectrometer (LC-MS/MS).
Billie Eilish and the Feminist Aesthetics of Depression: White Femininity, Generation Z, and Whisper Singing
Authors: Holmes Jessica A. 
Published: January 2024

Abstract
This article analyzes the representation of depression in Billie Eilish’s music and reception as reflective of its complex status in the West as a clinical diagnosis and lived experience, and considers the prominence of depression in contemporary pop as an aesthetic category dividing along generational, gendered, and racial lines. By claiming and musicalizing depression amid a polarizing reception, Eilish builds on a musical legacy of feminine psychological disturbance, challenging the stigmatization of “madness” in women and cultural panic over the prevalence of depression among Generation Z. Her music demystifies an invisible inner turmoil that her fans identify as “depression,” just as they frame her signature whisper singing as a coherent marker of and antidote for depression. Links between Eilish’s voice and the feminized auditory triggers of ASMR (a homemade sound-effects-based genre of audio-visual performance on YouTube) and the immersive, solitary listening characteristic of headphone and earbud use strengthen her music’s appeal as a form of “mood regulation.” Ultimately, Eilish’s voice and body are the locus onto which fans and detractors project fantasies and anxieties about the generational, gendered, and racial dynamics of depression that often exceed the singer’s stated aims as well as psychiatric definitions of clinical depression. Drawing on work in disability studies, Mad studies, and feminist media studies, I stake out new theoretical ground for analyzing depression in pop as distinct from the lived experiences and discursive logics of disability and madness, while positioning pop music as a creative site of public mental health discourse.
Pair potential description on phase stability variations in close-packed polytypism
Authors: Ogane Shinya , Moriguchi Koji 
Published: January 2024

AbstractWe report an extensive analysis on phase stability variations in close-packed (CP) polytypes, including hexagonal CP (hcp or 2H), face-centered cubic (fcc or 3C), and double hexagonal CP (dhcp or 4H) arrangements. This analysis involves the systematic development of interatomic pair potentials and the derivation of computational phase diagrams in the feature space of corresponding potential profiles. We focus on the following key components of interaction model: the reach distance of atomic interactions and perturbative long-range interactions reminiscent of Friedel oscillations which often lead to long-range interaction decay in crystalline materials. The computational experiments reveal that the perturbative interactions reflecting atomic local structures in CP polytypes, essentially diversify the polytypism in the phase diagrams. Using the pure La system with the 4H ground state, we also provide detailed procedures for creating practical pair potentials that approximately reproduce the energetics and physical properties deduced through the first-principles calculations.

Seismic Velocity Variations Observed Prior to the La Palma Volcano Eruption on 19 September 2021, in Cumbre Vieja, Canary Islands (Spain)
Authors: Mezcua Julio , Rueda Juan 
Published: January 2024

Abstract
In the recent years, coda-wave interferometry from seismic noise correlation functions has been increasingly used for volcanic eruption forecasting through velocity changes observed in the crust. Because La Palma Island in the Canary Archipelago is very well instrumented, we studied the possible velocity variations related to the last Cumbre Vieja eruption on 19 September 2021, aiming to obtain clear variations in the seismic velocity. For this purpose, we used the moving-window cross-spectral analysis technique for seismic noise within the 0.1–1.0 Hz frequency interval for determining two- and single-station cross-component correlations. During the 2018–2022 observation period, we first detected a seasonal seismic velocity variation possibly caused by annual rainfall and the induced pore pressure change. On 12 September 2021, a dramatic decrease in the velocity of −0.15% was detected, leading to the volcanic eruption at Cumbre Vieja seven days later. The results are compatible with those of models proposed for rapid magma migration from a shallow reservoir at 11 km to the surface.

Authors: Abrar, MES., PhD Ana Nadhya 
Published: January 2024

The position of the content creator team is very important for tribunjogja.com. They have a special position, so that the news manager just “relented” with their news. The question is, how does the tribunjogja.com content creator team place the idealism of journalists? To understand the idealism of the tribunjogja.com content creator team, this research uses a case study research method. Meanwhile, data collection was carried out using two data collection techniques, namely observation of news produced by the content creator team and in-depth interviews with M. Fathoni, editor of tribunjogja.com, who was not related to the content creator team and the leader of the tribunjogja.com content creator team, Mona. Kriesdinar. It turns out that the tribunjogja.com content creator team upholds their position as intellectuals. However, they are aware that tribunjogja.com cannot develop without positioning it as an economic institution. They make various adjustments. In that adjustment, they have a grip on the idealism of journalists: in line with the limits of reporting. From that adjustment was born reputation which raises the question for whom is the reputation.
An Integrated Model of WebQual 4.0 and SERVQUAL: Answer to the Next Research Call
Authors: Mardiana Siti 
Published: January 2024

In the original paper of WebQual 4.0, Barnes and Vidgen (2002) called for an improvement of their WebQual 4.0 model. Since WebQual 4.0 is a tool for assessing the quality of e-commerce websites, therefore a modification should be made in order to use WebQual 4.0 for other types of websites. This research offers an integrated model of WebQual 4.0 and SERVQUAL to fulfill the need. The proposed integrated model resulted in seven variables: Usability, Design, Information, Empathy, Responsiveness, Assurance, and Reliability. To test the model, a questionnaire based on the proposed model was created to assess the quality of a company website that is primarily used to manage employees’ data. There were 124 data samples that can be used for analysis. A spider web diagram was created based on the reliability (Cronbach’s alpha) scores to show the overall website quality. Based on the confirmatory factor analysis (CFA) results, it can be concluded that the integrated model that was created in this research was considered a good model. The implications and lessons learned from the study were discussed in the paper.

This paper aims to analyze the interconnectedness between Bond and Sukuk markets in the Gulf Cooperation Council (GCC) and Middle East and North Africa (MENA) countries. This study utilized the TVP-VAR extended joint connectedness method. The observed period was from January 2020 to October 2023, encompassing significant global events such as the COVID-19 pandemic, the Russia-Ukraine war, and the Israeli-Palestinian war. The results show the interconnectedness of bond and sukuk markets in both regions by 73% (based on TCI). The Bond and Sukuk instruments in MENA act as transmitters, while Bond and Sukuk in GCC act as receivers. The study suggests that the Sukuk in GCC and MENA may serve as an attractive option for diversified assets compared to Bonds. Additionally, the paper highlights structural changes and market dynamics during the crisis period that affected financial stability in both regions. The anticipated contribution of this study is to enriching the global economic in term of financial literature and offering policy insight to manage risks and improve financial system resilience in GCC and MENA countries.

Isolation of viable Plasmodium falciparum merozoites
Authors: Boyle Michelle , Wilson Danny , Beeson James 
Published: January 2024

Abstract
P. falciparum merozoites are the parasite form that infected red blood cells during blood-stage infection and replication. This method can be used to isolate P. falciparum merozoites that remain structurally intact and retain their invasive capacity. Merozoites can then be used in erythrocyte invasion assays, invasion inhibition assays, approaches to image merozoite invasion events by microscopy, evaluating immune responses to merozoites, and other applications.
