Published: March 2023

Abstract
Global raw material use has moved from a non-renewable to a renewable resource. Additionally, the research on epoxidation has produced a safer, more cost-effective, and ecologically friendly product than non-renewable resources. At present, there are limited studies on the production of epoxidized palm oleic acid using eco-friendly ion exchange resin method. Consequently, the objective of this study is to optimise the reaction conditions of epoxidation palm oleic acid using ion exchange resin (amberlite IR 120H) as a catalyst. Epoxidized palm oleic acid was prepared using performic acid formed in situ by mixing formic acid with hydrogen peroxide. The results showed that the optimum reaction conditions for the production of oxirane content were a temperature of 75 °C and a hydrogen peroxide concentration of 30%. The maximum relative conversion of palm oleic acid to oxirane was achieved using the optimum conditions with up to 75%. Finally, a mathematical model was developed using MATLAB and the fourth-order Runge–Kutta method was integrated with the genetic algorithm to determine the reaction rate, which was consistent with the experimental data. This study proved that palm oleic acid was successfully converted into a green epoxide that promotes the use of palm oil as a raw material.
Identifying Common and Idiosyncratic Explosive Behaviors in the Large Dimensional Factor Model with an Application to U.S. State-Level House Prices
Authors: Horie Tetsushi , Yamamoto Yohei 
Published: March 2023

Abstract
This study applies the date-stamping methodologies for explosive behaviors proposed in the seminal work of Phillips, P. C. B., and J. Yu. (2011. “Dating the Timeline of Financial Bubbles during the Subprime Crisis.” Quantitative Economics 2 (3): 455–91), Phillips, P. C. B., S. Shi, and J. Yu. (2015a. “Testing for Multiple Bubbles: Historical Episodes of Exuberance and Collapse in the S&P 500.” International Economic Review 56 (4): 1043–78), and Phillips, P. C. B., S. Shi, and J. Yu. (2015b. “Testing for Multiple Bubbles: Limit Theory of Real Time Detectors.” International Economic Review 56 (4): 1079–134) to a large dimensional factor model. To this end, we compare two methods of identifying common and idiosyncratic components: the Panel Analysis of Nonstationarity in Idiosyncratic and Common Components (PANIC) method by Bai, J., and S. Ng. (2004. “A Panic Attack on Unit Roots and Cointegration.” Econometrica 72 (4): 1127–77) and the Cross-Sectional regression (CS) method by Yamamoto, Y., and T. Horie. (2022. “A Cross-Sectional Method for Right-Tailed PANIC Tests under a Moderately Local to Unity Framework.” Econometric Theory (forthcoming)). We show that, when the explosive behavior lies only in the common component, the origination and termination dates are precisely estimated by either method. However, when the explosive behaviors exist in idiosyncratic components, only the CS method can detect them. We apply our method to the U.S. state-level real house price indices. We find that the 2000s boom was driven by not only the national bubble factors but also local components, while the 2010s onward expansion is dominated by the effect of national components.

Abstract

Introduction:
Listeria monocytogenes is an opportunistic foodborne pathogen that can cause death to infected humans. The bacterial pathogen was frequently associated with food-borne origins including seafood. Thus, the present study aimed at screening anti-listeria-producing lactic acid bacteria (AL-LAB) isolated from the intestinal tracts of wild gilt-head seabream (Sparus aurata).

Materials and Methods: Lactic acid bacteria (LAB) were isolated from the intestinal tracts of 15 wild gilt-head seabreams and screened for antimicrobial activity against Listeria monocytogenes. LAB isolated with the strongest anti-listerial activity was identified and further characterized for its anti-listerial compounds, followed by testing its protecting capacity on experimentally contaminated salmon fillets.

Results: Three out of 52 LAB showed antagonistic activities against the foodborne pathogen. Of these 3, an isolate with the strongest inhibitory activity was obtained from strain MA115 (>400 AU). Based on its 16S rDNA sequence, strain MA115 had 99% similarity to Enterococcus faecium (Acc. Nb: MG461637.1). Further in vitro assays showed that the anti-listerial compound was very sensitive to proteinase K which suggested that it is a bacteriocin-like inhibitory substance (BLIS). In addition, the BLIS was resistant to a wide range of pH (2–10), and low (4 to −20°C) as well as high temperatures (30−121°C). In addition, the BLIS showed bactericidal activity on L. monocytogenes in artificially contaminated Salmon fillets stored at 0°C.

Conclusion: The BLIS produced by Enterococcus faecium strain MA115 has the potential for application to improve food safety, although further studies are still required to specifically identify the BLIS, for biopreservation purposes.

The ability to extract rhythmic structure is important for the development of language, music, and social communication. Although previous studies show infants' brains entrain to the periodicities of auditory rhythms and even different metrical interpretations (e.g., groups of two vs three beats) of ambiguous rhythms, whether the premature brain tracks beat and meter frequencies has not been explored previously. We used high-resolution electroencephalography while premature infants (n= 19, 5 male; mean age, 32 ± 2.59 weeks gestational age) heard two auditory rhythms in the incubators. We observed selective enhancement of the neural response at both beat- and meter-related frequencies. Further, neural oscillations at the beat and duple (groups of 2) meter were phase aligned with the envelope of the auditory rhythmic stimuli. Comparing the relative power at beat and meter frequencies across stimuli and frequency revealed evidence for selective enhancement of duple meter. This suggests that even at this early stage of development, neural mechanisms for processing auditory rhythms beyond simple sensory coding are present. Our results add to a few previous neuroimaging studies demonstrating discriminative auditory abilities of premature neural networks. Specifically, our results demonstrate the early capacities of the immature neural circuits and networks to code both simple beat and beat grouping (i.e., hierarchical meter) regularities of auditory sequences. Considering the importance of rhythm processing for acquiring language and music, our findings indicate that even before birth, the premature brain is already learning this important aspect of the auditory world in a sophisticated and abstract way.SIGNIFICANCE STATEMENTProcessing auditory rhythm is of great neurodevelopmental importance. In an electroencephalography experiment in premature newborns, we found converging evidence that when presented with auditory rhythms, the premature brain encodes multiple periodicities corresponding to beat and beat grouping (meter) frequencies, and even selectively enhances the neural response to meter compared with beat, as in human adults. We also found that the phase of low-frequency neural oscillations aligns to the envelope of the auditory rhythms and that this phenomenon becomes less precise at lower frequencies. These findings demonstrate the initial capacities of the developing brain to code auditory rhythm and the importance of special care to the auditory environment of this vulnerable population during a highly dynamic period of neural development.

AbstractThe immunoproteasome is a specialized type of proteasome involved in MHC class I antigen presentation, antiviral adaptive immunity, autoimmunity, and is also part of a broader response to stress. Whether the immunoproteasome is regulated by DNA stress, however, is not known. We here demonstrate that mitochondrial DNA stress upregulates the immunoproteasome and MHC class I antigen presentation pathway via cGAS/STING/type I interferon signaling resulting in cell autonomous activation of CD8+ T cells. The cGAS/STING‐induced adaptive immune response is also observed in response to genomic DNA and is conserved in epithelial and mesenchymal cells of mice and men. In patients with idiopathic pulmonary fibrosis, chronic activation of the cGAS/STING‐induced adaptive immune response in aberrant lung epithelial cells concurs with CD8+ T‐cell activation in diseased lungs. Genetic depletion of the immunoproteasome and specific immunoproteasome inhibitors counteract DNA stress induced cytotoxic CD8+ T‐cell activation. Our data thus unravel cytoplasmic DNA sensing via the cGAS/STING pathway as an activator of the immunoproteasome and CD8+ T cells. This represents a novel potential pathomechanism for pulmonary fibrosis that opens new therapeutic perspectives.
Deconstructing ‘Canadian Cuisine’: Towards decolonial food futurities on Turtle Island
Authors: Mustapha Hana , Masanganise Sharai 
Published: March 2023

As scholars and community activists, to secure a just food system, we must first acknowledge our complicity in hierarchal power structures that shape structural inequities by questioning the underlying socio-political currents and interrogating the dominant relationships within our food system. In this commentary, the authors reflect upon their intersectional lived experiences interacting with food systems in the settler nation of Canada. They explore the complex interplay of systemic racism, settler colonialism and neoliberalism within the Canadian food system by deconstructing the indefinable essence of “Canadian cuisine” and mapping these situated insights onto the process of gastronomic multiculturalism. The authors provide their perspective that an entry point along the ongoing process of securing decolonial food futurities on Turtle Island requires a conscious commitment to building interrelational solidarity across differences, reckoning with colonial land politics and supporting food sovereignty for both racialized communities and Indigenous Peoples.
Confronting Anti-Black, Anti-Indigenous, and Anti-Asian Racisms in Food Systems in Canada
Authors: Deawuo Leticia Ama , Classens Michael 
Published: March 2023

The impetus for this themed section came out of the broader reckoning that touched off in the summer of 2020 in the wake of the murder of George Floyd. The Canadian Association for Food Studies board, like so many organizations struggling to respond to such brazen violence, released a statement on racialized police violence and systemic racism. In the statement the CAFS board commits to more deliberately centering the work of anti-racism in our association̶­ —and this included two shorter-term projects. Curating and publishing an open access resource list on food and racism in so-called Canada, and publishing a themed section on racism in the food system. The CFP for the special issue was released the following May, 2021, and read in part “As we reckon with the ways white supremacy, capitalism, patriarchy and colonization has shaped food systems, we must also reflect on and redress dominant modes of thought and approaches that reproduce inequity within the academy (e.g., research and teaching) and society at large. As such, we welcome submissions that centre diverse ways of knowing and methods of knowledge production.”
Over the past nearly two years, we (the special issue guest editor, Ama, and collaboration assistant, Michael) have met virtually many times to discuss the CFP, the process, the articles, and the broader backdrop of white supremacy, colonialism, and capitalism. And as we reflected on how we wanted to write this editorial, it occurred to us that our own approach to collaboration on this project has been relational, conversational. So, rather than writing a conventional editorial, we once again met virtually to reflect on some key themes that (re)emerged over the past couple of years. What follows is part of that conversation, edited for clarity and brevity. We hope this special issue contributes to keeping the conversations (and action) focused on structural change going.
Interventions in spontaneous developed public spaces

Published: March 2023

AbstractPublic green spaces are very important in the urban structure, both on environmental and social level. Renovation may be necessary, but the process must involve complexity.The objective of this research is to define the main criteria of a successful renovation process, using two case studies - the Lucius-Burckhardt-Platz in Kassel, Germany, and the ‘Parku i lodrave’ in the city of Peja, Kosovo, where the recent intervention had rather negative effects. The paper considered aspects as community activity, key functions, visual elements, accessibility, safety, well-being and maintenance.The transformation of these spontaneously developed, liveable spaces into renewed but abandoned parks was explained by the lack of correlation between the analysis of function, public needs, and the dominance of aesthetics.
Dynamic behavior of gravity segmental retaining walls
Authors: Alsirawan Rashad , Alnmr Ammar 
Published: March 2023

AbstractThis work aims to highlight gravity segmental retaining walls with their varied advantages. The paper investigates the dynamic behavior analysis of segmental retaining walls. The stability analysis is conducted on the basis of a pseudo-static Mononobe-Okabe theory that provides safety factors against sliding and overturning failure. The results demonstrate that the crucial safety factor of internal stability is the safety factor against overturning. Moreover, the positive wall inclination angle contributes to an improvement in the stability of the segmental retaining walls and the effect of the vertical seismic coefficient on the stability can be disregarding. Finally, a new equation is proposed for the elementary design of the segmental retaining walls.
Design and theoretical characterization of neomycin-guanine and neomycin-thymine using DFT methods
Authors: Hernández Castillo Juan Martín , Molina Brito Bertha , Soto Mercado Jorge Ramón , Francisco Santiago Pedro 
Published: March 2023

AbstractNeomycin B is a drug of the bacteriologic category of aminoglycosides, built by four sugar rings joined with glycosidic bonds, that recently has attracted a lot of attention because its derivatives have shown anti-carcinogenic and antiviral properties, in addition to some gene therapy applications. Although some derivatives have been synthesized, there are no theoretical studies about them. In this work, we carried out DFT calculations to predict and study stable neomycin B derivatives, obtained by substituting its first ring by Thymine, as done in previous experiments, and for Guanine as a theoretical proposal. For the two nucleobases, we obtained stable quasi-degenerated structures, pointing out that there is equal probability to synthesize their isomers. Moreover, we calculated the electrostatic potential surface to elucidate the long-range interaction mechanism.

The 2022 Mw 6.7 Menyuan Earthquake on the Northeastern Margin of the Tibetan Plateau, China: Complex Surface Ruptures and Large Slip
Authors: Niu Pengfei , Han Zhujun , Li Kechang , Lv Lixing , Guo Peng 
Published: March 2023

ABSTRACT
On 8 January 2022, the Mw 6.7 Menyuan earthquake occurred near the stepover of the Lenglongling (LLLF) and Tuolaishan (TLSF) faults of the Qilian–Haiyuan fault zone in the middle of the northeastern Tibetan plateau. Field investigations and unmanned aerial vehicle-based photogrammetry revealed that the earthquake generated five surface rupture zones with different strikes and kinematic properties. Two large rupture zones, R1 (∼22.8 km long) and R2 (∼3.9 km long), occurred along the northern branch of the western LLLF and the eastern segment of TLSF, respectively, and featured left-lateral strike slips. Among the three small rupture zones, the left-lateral strike-slip-type R3 (0.6 km long) was located in the extension direction of R2, whereas the thrust-type R4 (∼3.3 km long) and R5 (∼1.1 km long) zones were located north of the central section of R1. These complex multifault ruptures were caused mainly by the rupture of strike-slip faults on both sides of the stepover structure. A small amount of compressive shortening strain was released during the earthquake due to regional oblique compression. The total length of the rupture zone was ∼31.7 km; the maximum left-lateral and vertical offsets were 3.5 ± 0.3 and 0.47 ± 0.04 m, respectively. Compared with the relationship observed between coseismic slips and magnitudes in historical and modern earthquakes in western China, the 2022 Menyuan earthquake produced a large coseismic slip in relation to its magnitude. The distribution characteristics of the aftershock belts and their relationship with rupture zones showed that the seismogenic fault of the earthquake was nearly east–west-striking TLSF, which may have triggered the rupture of the northern branch of the western LLLF. In addition, only a small segment of TLSF was ruptured, indicating that the accumulated strain could not be released completely during the earthquake and that this remains the most likely area for the occurrence of large earthquakes in the future.

The paradox of rural tourism and poverty alleviation
Authors: Martini Rina , Agustin Esther Sri Astuti Soeryaningrum , Setiyono Budi 
Published: March 2023

This research aims to analyze factors determining the competitiveness of rural tourism and assess its performance compared to the poverty level in each province in Indonesia. We employ four main pillars: enabling environment; travel and tourism policy and enabling conditions; infrastructure; and natural & cultural resources adopted from the Travel and Tourism Competitiveness Index of the World Economic Forum 2019. We conducted fieldwork in four provinces, namely Aceh, Bali, Central Java, and North Sulawesi, by spreading questionnaires and giving semi-structured interviews to obtain respondents’ insights. The poverty gap index measures the intensity level of poverty by employing an expenditure-based poverty line. This study discovers that infrastructure, natural & cultural resources, and enabling environment support rural tourism development in each province. We also find that the excellent performance of rural tourism competitiveness seems to have minimal impact on poverty. Bali has become the major icon of tourism in Indonesia; ironically, its poverty level is relatively higher than in other areas. Meanwhile, Central Java ranks as the second most competitive province after Bali, while the poverty level is the lowest. Our study offers community-based tourism (CBT) and corporate social responsibility (CSR) to resolve the situation.

Portrait of Indonesian Religious Communities Attitudes toward the Government Policies Restriction on Congregational Worshipping
Authors: Sardjuningsih Sardjuningsih 
Published: March 2023

<p>Many offenses have been perpetrated by Indonesian religious communities toward the government’s policies on the restriction of congregational worshipping during the COVID-19 pandemic. However, scant studies investigating those negative attitudes using a qualitative approach. In order to fill the gap, this paper reports on the religious attitudes of Muslims who are considered to violate the restriction policy on religious activities ordered by the Indonesian government. The involved participants were policymakers, mosque caretakers, and the three largest Muslim social groups, including Muhammadiyah, Nahdlatul Ulema (NU), and traditionalists. The results of this study revealed discrepancies in how Muslims' polarized religious attitudes are constructed. These communities have different patterns of thought and diversity in terms of perceiving the government’s policies. This study suggests that there is a critical role for Islamic scholars in educating Muslims about the dangers and possible consequences of COVID-19. In other words, following government policies while partaking in congregational worship can be interpreted as a manifestation of social piety, spiritual activity, and religious faith.</p>
