The Friedmann–Lemaître–Robertson–Walker metric and the principle of equivalence
Authors: Melia Fulvio
Published: August 2023

The evidence in favor of a Universe expanding at a constant rate, in contrast to the various episodes of deceleration and acceleration expected in the standard model, has been accumulating for over a decade now. In recent years, this inference has been strengthened by a study of the Friedmann–Lemaître–Robertson–Walker (FLRW) metric in relation to Einstein’s principle of equivalence. This earlier work concluded that the choice of lapse function g_tt = 1 characterizing the FLRW solution to Einstein’s equations is inconsistent with any kind of accelerated cosmic expansion. In this paper, we demonstrate and confirm this important result by directly testing the self-consistency of four well-known FLRW cosmologies. These include the Milne universe, de Sitter space, the Lanczos universe, and the R_h = ct model. We show that only the constantly expanding models (Milne and R_h = ct) are consistent with the principle of equivalence, while de Sitter and Lanczos fail the test. We discuss some of the many consequences of this conclusion.
Model selection using time-delay lenses
Authors: Melia Fulvio , Wei Junjie , WU Xuefeng
Published: August 2023

The sample of time-delay gravitational lenses appropriate for studying the geometry of the Universe continues to grow as dedicated campaigns, such as the Dark Energy Survey, the (Very Large Telescope) VLT Survey Telescope (VST) ATLAS survey, and the Large Synoptic Survey Telescope, complete their census of high-redshift sources. This catalogue now includes hundreds of strong lensing systems, at least 31 of which have reasonably accurate time-delay measurements. In this paper, we use them to compare the predictions of two competing Friedmann-Lemaître-Robertson-Walker models: flat Lambda cold dark matter (ΛCDM), characterized by two adjustable parameters (H0 and Ωm), and the Rh = ct universe (with H0 as the single free variable). Over the past decade, the latter has accounted for the data better than the standard model, most recently the emergence of well-formed galaxies discovered by JWST at cosmic dawn. Here, we show that the current sample of time-delay lenses favours Rh = ct with a likelihood of ~ 84 per cent84 per cent versus ~ 16 per cent16 per cent for the standard model. This level of accuracy will greatly improve as the ongoing surveys uncover many thousands of additional lens systems over the next several years.

EBP is differentially expressed in central nervous system metastasis in human breast cancer.
Authors: Mamoor Shahan
Published: August 2023

Metastasis to the brain occurs in a significant fraction of patients with breast cancer (1-3). We mined published RNA-sequencing and microarray data (4, 5) to compare primary and metastatic tumor transcriptomes for the discovery of genes associated with brain metastasis in humans with metastatic breast cancer. We found that emopamil binding protein (sterol isomerase), encoded by EBP, was among the genes whose expression was most different in the brain metastases of patients with metastatic breast cancer as compared to primary tumors of the breast. EBP mRNA was present at increased quantities in brain metastatic tissues as compared to primary tumors of the breast. Expression of EBP in primary tumors was correlated with patient distant metastasis-free survival. Modulation of EBP expression may be relevant to the biology by which tumor cells metastasize from the breast to the brain in humans with metastatic breast cancer.
Classification of Phishing Website Using Hybrid Machine Learning Techniques
Authors: Choudhury Ziaul Haque
Published: August 2023

The problem with cyber security involves scam websites, stilling the information that exploit people's trust. It could be reduced to the act of enticing internet users even though that they can get their personal data, including user names and passwords. In this study, we present a method for identifying phishing websites. The technology works as an add-on to a web browser, alerting the user when it finds a phishing website. A machine learning technique, specifically supervised learning is proposed in our study. The Logistic regression, Principal Component Analysis (PCA) and Apriori algorithms are chosen because of its success in classification. By examining the characteristics of phishing websites and selecting strongest combination of them, we developed a classifier that performs better.
The Impact of the Big Five Personality Traits on Help-Seeking Stigmas, Attitudes, and Intentions
Authors: Murphy Dallas James , Mackenzie Corey S.
Published: August 2023

Mental illness is common, consequential, and increasing in prevalence. Despite this, mostindividuals do not seek professional help for mental health concerns. Research has begun to investigatethe impact of personality on help-seeking, but it has suffered from many limitations. As such, thepurpose of this study was to establish the effects of the Big Five personality traits on public and selfstigmaof seeking help, help-seeking attitudes, and intentions. We employed hierarchical regressionmodels in a large cross-sectional sample (N = 5712) to evaluate personality traits in the context of otherestablished predictors of help-seeking. Agreeableness had consistent protective effects across all modelsand extraversion was especially protective regarding help-seeking intentions. In contrast to thesebeneficial effects, openness, conscientiousness, and neuroticism had complex relationships with help-seekingconstructs. Our findings have implications for understanding the influence of the Big Five onwhich individuals may be unlikely to seek mental health services in the face of a need. Through thisunderstanding, we can begin to develop targeted strategies directed towards individuals at risk to notseek help for mental health concerns, and increase help-seeking behaviour.
Perceived Environmental Impact of Livestock Production -- Determinants of Risk Perception
Authors: Veneny Marek
Published: August 2023

Through overuse of land and its deforestation, pollution of water bodies, and a substantialrelease of greenhouse gas emissions (GHG), the livestock industry poses a majorenvironmental hazard. However, to which extent it is perceived as such has not yet beenextensively investigated. In a cross-sectional study using an online questionnaire, 210participants were asked about various determinants of risk perception of the livestockindustry. The collected data were analyzed using correlations and multiple hierarchicalregression analyses. In the final model, 4 determinants emerged as stable and significantpredictors of livestock industry risk perception: holistic affect, prescriptive social norms,biospheric, and socio-altruistic value orientations. The final model explained around 52%of unique variance. Contrary to expectations, socio-demographic factors, knowledge,carnistic beliefs, sustainable diet, and personal experience did not predict participant’s riskperceptions. The results suggest that to effectively communicate the risks of the livestockindustry, the interventions would profit from targeting emotion, the normative expectationsof important social referents, and make the relevant value orientations salient. Furtherresearch is needed to experimentally prove the results of this study, and to determine whatother factors might play a role in risk perception of the livestock industry.
The time-dependent Ising model: An idiographic hidden Markov process for modelling binary network data
Authors: Failenschmid Jan Ian , Marsman Maarten
Published: August 2023

Network models have gained significant popularity in the field of psychology over the past decade. The Ising model specifically is widely used for analyzing binary cross-sectional data. This paper extends the Ising model to incorporate a temporal dimension. The proposed time-dependent Ising model is based on Fortuin and Kasteleyn’s (1972) theory of the random-cluster model, which introduces heterogeneity to the Ising model and allows for individualized network topologies. To introduce temporal dynamics, we apply a hidden Markov process that allows the idiographic topologies to transition into different states over time. Thisallows the model to capture individual progressions through time, in a group level change process within the hidden Markov chain. We present a candidate probability distribution for the transitions of the idiographic topologies and derive the resulting distributions for the complete Markov chain as well as the time-dependent Ising model. Moreover, we demonstrate how the model induces heterogeneity in the association parameters of the Ising model, both acrossindividuals and time points. Then, we illustrate the implied auto- and cross-lagged correlations between the observed variables. Through simulations, we show that estimators for the cross-sectional Ising model are unbiased for the expectation of the individual association paramters. These simulations also illustrate some of the behaviors the model exhibits. Specifically, we show how the model may be used to conceptualize cognitive growth. In conclusion, we present a comprehensive overview of a time-dependent Ising model for heterogeneous panel data that is based on a strong theoretical foundation.
What is a 'note'? Agreement and disagreement in transcriptions of Japanese folk songs
Authors: Chiba Gakuto , Ozaki Yuto , Savage Patrick E.
Published: August 2023

What is a musical “note”? Previous analysis of cross-cultural transcription using Western staff notation suggests that disagreement about how to conceptualize a “note” is the main factor limiting transcription agreement and reliability. In min’yō (Japanese folk songs), melodies are traditionally highly ornamented and taught via oral transmission without written notation. Min’yō thus represents a good case study to investigate agreement and disagreement in how musical “notes” are conceptualized and perceived in an orally transmitted musical culture. In this report, we focus on differences in transcription of Japanese folk songs by Japanese listeners with and without experience singing them. We used Tony and Sonic Visualiser to automatically extract fundamental frequencies without constraining pitches to equal temperament or forcing note onsets into a metrical structure. Two of us (first and second authors) independently segmented 9 audio recordings of min’yō (the first verse of three songs - Kuroda-bushi, Esashi-Oiwake and Yagi-bushi - in three different versions, totalling approximately 12 minutes) into what we perceived as notes and then compared our note segmentations against each other using quantitative and qualitative analysis. Our analyses suggest general agreement but with substantial variation (57-96% agreement depending on the song/performer/agreement metric), but they also delineate that different conceptualizations of “note” can lead to contrasting segmentation results. In particular, the first author (an experienced Japanese folk singer) showed higher sensitivity to microrhythm and microtonality, while the second author segmented into longer acoustic units using continuous pitch and linked acoustic units to the mora-like unit as seen in the notation of Japanese vocal music. Our results reveal within-culture variation in music perception, with implications for cross-cultural analysis of music based on transcription into musical “notes”.
The Compassionate Brain Theory of Autism
Authors: Galvin John
Published: August 2023

In this paper I present the “Compassionate Brain Theory”, which is a wellbeing theory of autism rooted in compassion. At its core, this theory explores how a person’s distribution of compassion resources, balancing self-compassion and compassion for others, can impact their overall well-being. Specifically, a condition characterised by notable disparity - where compassion is predominantly directed towards others while being notably limited for oneself (referred to as the self-other imbalance) - is said to result in diminished mental and physical health, as well as reduced quality of life. In relation to autism, I put forward the hypothesis that significantly higher self-other imbalance will be found in autistic compared to non-autistic individuals. That is, on average, autistic people will display a highly compassionate brain profile, characterised by high compassion for others and low compassion for self. I further hypothesise that self-other imbalance will be associated with a person’s health outcomes. I present some initial data to lend support to this theory and explore potential directions for future research.
The Dual-Feature Approach-Avoidance Task: Validity, Training Efficacy, and the Role of Contingency Awareness in Changing Food Preference
Authors: Kahveci Sercan , van Alebeek Hannah , Blechert Jens
Published: August 2023

The approach-avoidance task (AAT) probes tendencies contributing to unwanted behaviors, like excessive snacking, by measuring RT differences between approach and avoidance responses to different stimuli. It retrains such tendencies using repeated avoidance of appetitive stimuli and approach of healthy alternatives. The most common paradigm, the irrelevant-feature AAT, conceals these stimulus-response contingencies by requiring approach or avoidance based on features irrelevant to the tendencies (e.g. frame color). Unfortunately, it is an unreliable measure and not always successful as a training, likely because the stimuli can be ignored. In the novel dual-feature AAT, the combination of stimulus and irrelevant feature determines responses: participants approach foods and avoid objects surrounded by frame A, and vice versa given frame B. We trained 219 online participants to approach fruit and avoid chocolate using active (7:1 stimulus-to-frame contingency) and sham (1:1 stimulus-to-frame contingency) versions of these two trainings. Compared to sham, active irrelevant-feature training was associated with more selection and desire to eat fruit, and active dual-feature training increased approach bias for fruit. Participants’ perceived rate of approaching fruit versus chocolate correlated with many outcome measures, suggesting contingency awareness plays a major role in AAT training effectiveness, challenging implicit accounts. While the dual-feature paradigm shows potential, its high error rates, RTs, and difficulty mandate improvement.
The Politics of Curating Japonisme: International Art Exhibition and Soft Power in Contemporary Japanese Cultural Diplomacy
Authors: Ma Scott
Published: August 2023

This article studies the Paris exposition Japonismes 2018, organized by the Japanese government to introduce the European public to the profundity of Japanese culture. It examines the organizational deliberations leading up to the exposition; the curation of individual exhibits held within its ambit; and the cultural politics of ‘Japan expositions’ that began with Japonismes and continue to this day. It argues that the organizers and exhibits in Japonismes make political use of the trope of a timeless, mystical, and animistic Japanese sense of beauty that supposedly unites prehistoric pottery and contemporary comics and animation. This Japanese aesthetic vision claims to provide an alternative to Western norms, thereby promising to resolve contemporary problems, such as anthropocentrism, by influencing Western aesthetics as it had in the late nineteenth century. Japonismes exemplifies how Japanese soft power diplomacy can employ Western tropes about Japan, such as Japonisme, for its economic and nation- branding efforts.

Published: August 2023

Introduction: Oral Health status in children has been shown to be related with oral health patterns learned through the childhood. The children acquire health behaviors from their mothers.
Objective: This study aims to assess the oral health related knowledge and practice among mothers in a rural municipality of Eastern Nepal and explore the factors associated with these outcomes.
Methods: A randomly selected 268 women either pregnant or having children of less than 6 years of age were interviewed in April- June, 2019 to assess their knowledge and practice regarding oral health. Data was entered using Epidata 3.1. Response on knowledge and practice were presented as frequency and proportion and compared with different maternal variables using inferential statistics.
Results: Mean age of the participating women was 25.9 years (SD 5.3). Three participants were pregnant (primigravida). Majority (96.7%) of respondents reported brushing their teeth at least once a day. Only 9.3% reported using fluoridated toothpaste for their children. Similarly, majority (69.4%) of participants had knowledge about wiping baby’s gums after breastfeeding or after letting child bottle feed. Literacy was found to significantly influence the participants’ brushing frequency, brushing technique, practice of brushing or wiping their child’s teeth and gums.
Conclusions: Oral health related knowledge among mothers and their practice were found to be unsatisfactory across several domains. Further, these outcomes were found to be influenced by several maternal characteristics. Assessing knowledge-practice gap on oral health resulting from maternal characteristics can provide a basis for providing training to women on necessary parenting skills.

Published: August 2023

Introduction: Airtight sealing of the root canal is the foremost desirable result of any root canal treatment, but getting the perfect filling of the root canal is always problematic, which could be due to multiple reasons. One such majorly reason impacting the obturation is the root canal sealer utilized.
Objective: The present study was done for evaluating microleakage in zinc oxide eugenol cement (ZOE) and epoxy resin-based sealer (AH Plus) root canal sealers using linear dye leakage method.
Methods: This in-vitro study used twenty-two extracted human single canal mandibular premolar teeth comprising 2 groups (11 in each), where sealers used for microleakage evaluation were ZOE cement sealer, and AH Plus. All the samples once cleaned, shaped and obturated were soaked in methylene blue dye for forty-eight hours with two millimeter (mm) exposed apex. The samples were then split into halves and inspected under a stereomicroscope for microleakage. The generated data were statistically analyzed using an independent t-test in SPSS version 11.
Results: All the test samples showed microleakage. However, the mean microleakage measured was considerably higher in the ZOE cement sealer at 6.18mm and 2.95mm for the Epoxy resin-based sealer (AH Plus sealer).
Conclusions: Epoxy resin-based sealer has better performance than ZOE cement sealer with minimal microleakage. Thus, Epoxy resin-based sealer showed a better prognosis and it can be considered to be adapted in clinical practice.

Introduction: The mandible is one of the largest and most rigid bone in the facial skeleton. The mandibular parameters like gonial angle, bigonial width and ramus heights can be used to determine a correlation with an individual’s age and gender. This can be an important legal ramifications and its assessment has a great role in forensic and orthodontic purposes.
Objective: To assess the radiographic correlation of gonial angle with age and gender.
Methods: A total of 325 Orthopantomographs (OPG) were evaluated which included 168 male and 157 female dentate subjects. It was further categorized into three groups: Group I (3-9 years), Group II (10-15 years) and Group III (16-17 years). The gonial angle was measured bilaterally and the data were statistically analyzed.
Results: The mean age of the subjects was 12.24+3.79 yrs. The mean values (in degrees) of right (126.71+5.89) and left gonial angles (129.92+5.86) were higher on females compared to males. However, it was not statistically significant. The mean values of right and left gonial angles were higher on the age group 8-12yrs (126.70+ 6.52 and 128.56+ 5.83) and lowest on the age group 13-17yrs (125.40+ 6.84 and 126.93+7.35) which also showed statistically insignificant in all age groups.
Conclusions: The morphometric analysis of the mandible through radiographic measurements may be useful in estimating an individual’s age and gender when comparing to known population. Gonial angle has been used as an adjunct parameter which has an implications on forensic identifications as well as orthodontic analysis.

Archaeometallurgical Fracture Analysis
Authors: Wanhill Russell , Oudbashi Omid
Published: August 2023

This article provides an overview of cracking and fracture mechanisms in heritage gold, silver, low-tin bronze, and wrought iron alloys. Understanding these mechanisms can be important for restorers, and possibly for conservators and curators as well. Metallography is widely used (when sampling is permitted) for studying archaeometallurgical artifacts in detail. However, fracture surface examinations and analysis (i.e., fractography) can often provide even greater insight. Case studies demonstrate the benefits of employing fractographic analysis to study cracking and fracture mechanisms in heritage alloys.

Authors: Cotton James D. , Wolodko John D.
Published: August 2023

A search for alternative, sustainable tonewood species has been prompted by constraints in availability and concerns about ecological impacts associated with established sources. This article describes an effort to identify tonewood substitutes for guitar soundboards using the ANSYS Granta Selector based on derived performance objectives for physical and mechanical properties. These objectives are then combined with those for species morphology, producibility, and sustainability to arrive at sustainable and viable tonewood substitution options that meet manufacturer and customer expectations.
Keeping EV Lithium-Ion Batteries "Green" With CT-Scan Data Analysis
Authors: Pinter Pascal
Published: August 2023

Fire risk in electric vehicle batteries can be reduced by detecting flaws through nondestructive visualization. Industrial computed tomography (CT scanning) combined with advanced software that makes sense of CT-generated images, allows users to measure voids and particle sizes within electrode active material during the research and development phase, detect delamination and contamination during cell manufacturing, analyze electrical connections and electrolyte fill levels, and provide many other quality-assurance functions that were once impractical or even impossible to perform.

The objective of this study is to use statistical means in the optimal plot sizing for the culture of Mombasa grass. For this, data from a uniformity test will be analyzed in a total area of 100 m², with 400 basic experimental units (BEU), where each sampled plot had a usable area of 0.25 m². The experiment was conducted in the rural area of the municipality of Adelândia, Goiás. The climate of the region is classified as AW-tropical, with a dry season in the winter. In the implementation of the experiment, an application of chicken litter at 18 tons per hectare was made. For the selection of the experimental area, a place where the soil cover was more uniform was taken into account. However, due to the lack of management, the height of the grass within the experimental area was uneven. In view of this, it was necessary to perform a standardization cut throughout the plot. The cut samples collected were stored in paper bags and the production of green mass was measured. For the dry mass, 40 samples were randomly selected, where each one went through the drying process in a microwave. This drying process consists of weighing and marking the initial weight of the sample, putting two containers in the microwave for three minutes, one with water and the other with the sample. The methods used for this design were: maximum curvature model method of the coefficient of variation; linear segmented model method with plateau, and quadratic segmented model method with plateau. The analyzed models presented different plot sizes, with approximate values of 1 m2, 7.4 m2 and 14 m2, respectively. As a methodology for selecting the model that best fits the observed data, the Akaike information criterion (AIC) will be used. This is a relative measure of the quality of a statistical model’s fit. For a set of experimental data, the accepted model will be the one that presents the lowest value for AIC, that is, the lower the value for AIC, the better the model fits the data. We can conclude that the unsegmented method presented optimal plot size, with an area of 1 m2, plots of 4.3, a coefficient of variation of 27.2 and an AIC of 188. The linear segmented model with plateau and quadratic segmented model with plateau presented AIC values of 199 and 198, respectively.
On the emergence of new branches in the Ukrainian legal system
Authors: Zemko Alla , Pundor Yulia
Published: August 2023

The article analyses the current approach to the allocation of new branches in the legal system of Ukraine. The modern world does not stand still and is constantly evolving, giving impetus to the development of all spheres of human life, and, accordingly, relations arise which require legal regulation. Some scholars believe that if there is an independent subject of legal regulation, its own methodology of legal regulation and a set of specialized legislative acts, it is possible to distinguish an autonomous branch of law. The author determines that the emergence of new branches of law is hindered by the dominant concept of the existence of only the main ones. Proponents of this concept categorically reject the possibility of the existence of relevant secondary, complex branches of law. This scientific approach hinders the study of modern social legal relations. A negative attitude to the separation of new branches of law inevitably leads to gaps in the field of special legal research and, as a result, to a shortage of qualified personnel with specialized knowledge. It is necessary to take into account the positive experience of foreign lawyers who boldly present the developments of current practices and are not afraid to consider them as branches of law, we mean educational, sports, military, gender, “cryptocurrency”, admiralty, law, etc. The author concludes that the division of law into new branches makes it possible to regulate legal relations in the relevant areas of activity more effectively, given that global trends are increasingly demanding universal lawyers, but with specialization, with in-depth knowledge in a particular or several branches of law.
