Published: March 2024

Background
Socioeconomic inequality in antenatal care visits is a great concern in developing countries including Bangladesh; however, there is a scarcity of investigation to assess the factors of inequality and these changes over time. In this study, we investigated the trend of socioeconomic inequalities (2004–2017) in 1+ANC and 4+ANC visits, and extracted determinants contributions to the observed inequalities and urban-rural disparities in Bangladesh over the period from 2011 to 2017.

Methods
The data from the Bangladesh Demographic and Health Surveys (BDHS) conducted in 2004, 2007, 2011 and 2017 were analyzed in this study. The analysis began with exploratory and bivariate analysis, followed by the application of logistic regression models. To measure the inequalities, the Erreygers concentration index was used, and regression-based decomposition analyses were utilized to unravel the determinant’s contribution to the observed inequalities. The Blinder-Oaxaca type decomposition is also used to decompose the urban-rural disparity into the factors.

Results
Our analysis results showed that the prevalence of 1+ANC and 4+ANC visits has increased across all the determinants, although the rate of 4+ANC visits remains notably low. The magnitudes of socioeconomic inequality in 4+ANC visits represented an irregular pattern at both the national and urban levels, whereas it increased gradually in rural Bangladesh. However, inequalities in 1+ANC visits declined substantially after 2011 across the national, rural and urban areas of Bangladesh. Decomposition analyses have suggested that wealth status, women’s education, place of residence (only for 4+ANC visits), caesarean delivery, husband education, and watching television (TV) are the main determinants to attribute and changes in the level of inequality and urban-rural disparity between the years 2011 and 2017.

Conclusions
According to the findings of our study, it is imperative for authorities to ensure antenatal care visits are more accessible for rural and underprivileged women. Additionally, should focus on delivering high-quality education, ensuring the completion of education, reducing income disparity as well as launching a program to enhance awareness about health facilities, and the impact of caesarean delivery.
The reality of the not-true in Plato's Sophist
Authors: Cordero Néstor Luis 
Published: March 2024

The definition of the sophist as "image-maker" allows Plato to add to the novelties he presents in the Sophist two topics he hadn't deepened in his previous dialogues: (a) a "definition" of being (247e) and (b) the influence this position will have on the relationship between image and truth. From a first definition of the image proposed by Theaetetus in 240a we deduce that, even if it is not true, it is "really" (ὄντως) an image, which does not coincide with the devalued or secondary reality that Plato had always attributed to this notion, from which all truth was absent. This conclusion, indeed, astonishes Theaetetus, attached to the Platonic "orthodoxy". This astonishment is not present in the orthodox version of the text of the passage 240a-c of the Sophist, which inherits from a modification of the widespread text from 1851. Once the original version is restored, the definition of the fact of being proposed in 247e justifies the "really real" character of the image, which respects the condition required to everything that "possesses" being: the possibility of acting or being affected. Indeed, the image is "affected" by the model, that it tries to imitate, because the model "affects" it. The image, even if it is not true, is real.
Olive Oil Drops and Their Effect on Earwax Accumulation
Authors: Levy Mary 
Published: March 2024

Abstract

Ear wax is a normal secretion that is produced by specialised glands in the ear. In medical terms earwax is called cerumen, a combination of natural oily secretions from the ceruminous glands, dead skin cells and debris, and serves a very significant purpose. In the majority of cases, ear wax does not need to be removed. The waxy substance protects the ear canal against dust, pollen and water, and due to its acidity is bacteriostatic i.e. it discourages the multiplication of bacteria. It also lubricates the skin lining of the ear canal, preventing the skin from drying out.
The focus of the research is to investigate the application of olive oil and its impact on accumulation of wax to adults. In this research, the participants were invited to attend one of our selected clinics in London on a specific date. Their ears were examined thoroughly for any wax occlusion or other pathology and wax was removed and/or medical referral was made as necessary. They were briefed to use a type of olive oil of their preference in just one ear at a given interval, and attend approximately every two weeks for a period of 24 weeks for the researcher to visually estimate the percentage of wax occlusion in both ears. The study showed that in the majority of cases, olive oil drops do not reduce earwax build-up. The review was restricted to a small cohort of volunteers (N = 60) and therefore the result was potentially weak.
The principal finding of the study is that contrary to current recommendations, the regular application of olive oil hastens the accumulation of ear wax in individuals susceptible to ear wax occlusion.

Published: March 2024

Abstract
This report investigates a stabilization method for first order hyperbolic differential equations applied to DNA transcription modeling. It is known that the usual unstabilized finite element method contains spurious oscillations for nonsmooth solutions. To stabilize the finite element method the authors consider adding to the first order hyperbolic differential system a stabilization term in space and time filtering. Numerical analysis of the stabilized finite element algorithms and computations describing a few biological settings are studied herein.

Euler’s integral, multiple cosine function and zeta values
Authors: Hu Su , Kim Min-Soo 
Published: March 2024

AbstractIn 1769, Euler proved the following result:∫0π2log⁡(sin⁡θ)⁢𝑑θ=-π2⁢log⁡2.\int_{0}^{\frac{\pi}{2}}\log(\sin\theta)\,d\theta=-\frac{\pi}{2}\log 2.In this paper, as a generalization, we evaluate the definite integrals∫0xθr-2⁢log⁡(cos⁡θ2)⁢𝑑θ\int_{0}^{x}\theta^{r-2}\log\biggl{(}\cos\frac{\theta}{2}\biggr{)}\,d\thetaforr=2,3,4,…r=2,3,4,\dots . We show that it can be expressed by the special values of Kurokawa and Koyama’s multiple cosine functions𝒞r⁢(x){\mathcal{C}_{r}(x)}or by the special values of alternating zeta and Dirichlet lambda functions. In particular, we get the following explicit expression of the zeta value:ζ⁢(3)=4⁢π221⁢log⁡(e4⁢Gπ⁢𝒞3⁢(14)162),\zeta(3)=\frac{4\pi^{2}}{21}\log\Biggl{(}\frac{e^{\frac{4G}{\pi}}\mathcal{C}_{% 3}\bigl{(}\frac{1}{4}\bigr{)}^{16}}{\sqrt{2}}\Biggr{)},whereGis Catalan’s constant and𝒞3⁢(14){\mathcal{C}_{3}(\frac{1}{4})}is the special value of Kurokawa and Koyama’s multiple cosine function𝒞3⁢(x){\mathcal{C}_{3}(x)}at14{\frac{1}{4}}. Furthermore, we prove several series representations for the logarithm of multiple cosine functionslog⁡𝒞r⁢(x2){\log\mathcal{C}_{r}(\frac{x}{2})}by zeta functions,L-functions or polylogarithms. One of them leads to another expression ofζ⁢(3){\zeta(3)}:ζ⁢(3)=72⁢π211⁢log⁡(3172⁢𝒞3⁢(16)𝒞2⁢(16)13).\zeta(3)=\frac{72\pi^{2}}{11}\log\Biggl{(}\frac{3^{\frac{1}{72}}\mathcal{C}_{3% }\bigl{(}\frac{1}{6}\bigr{)}}{\mathcal{C}_{2}\bigl{(}\frac{1}{6}\bigr{)}^{% \frac{1}{3}}}\Biggr{)}.

Published: March 2024

Abstract
This study investigated the inhibition effect of nanoscale silver–copper particle (20 nm) against Coriolus versicolor and Gloeophyllum
trabeum. Poplar wood samples (Populus L.) were vacuum-impregnated using aqueous nano-AgCu solutions at concentrations of 0.01 %, 0.02 %, 0.03 %, 0.05 %, 0.075 %, and 0.1 %. Alkaline copper quaternary (ACQ, 0.1 %), boric acid (0.2 %) and untreated control group (CK) were employed for comparisons. Decay resistance and leachability were studied. The anti-fungi effects were compared between nano-AgCu, nano-Ag, Ag+ (silver nitrate), Cu2+ (copper nitrate), and a composite of Ag+–Cu2+. Nano-AgCu particle exhibited effective resistance to fungi after 12 weeks of exposure. The threshold retention of the nano-AgCu against C. versicolor and G. trabeum on poplar wood was 0.19 kg m−3 and 0.62 kg m−3, respectively. The silver–copper nanoparticles demonstrated excellent leach resistance, and the inhibition effect was retained after leaching. The nano-AgCu particle provided better antifungal effects than single ions or metal nanoparticles. This study illustrates the potential of using nano-AgCu particle as an efficient wood preservative compared to commercial water-soluble preservatives.

Unravelling Power of the Unseen: Towards an Interdisciplinary Synthesis of Generative AI Regulation
Authors: Cheng Le , Liu Xiuli 
Published: March 2024

Abstract
The regulations of generative AI, typified by ChatGPT and Sora, have become one of the most influential alternative technological imaginaries. Developed by states and civil society groups, such regulations are triggering a broad range of social actors seeking to nominalize the AI-related behavior. Against this backdrop, this study starts with interrogating the semiotic character of generative AI. Do these regulations support the AI futures, or do they involve a mere change in the social actors who benefit from the technological status quo? To answer this question, this study examines the rhetoric and realization of AI regulations by the European Union and the United States. The findings reveal a degree of AI regulatory alignment between the European Union and the United States, but these two jurisdictions also highlight and predict some structural challenges. Drawing upon the concept of panopticism by Foucault, the study explores the foundational origins of challenges by dissecting the (in)visibility of AI power. It underscores the necessity of regulating the power of the unseen and proposes a synthetic generative AI regulatory framework. We finally conclude that the integrity of sociosemiotics and panopticism provides a productive and paramount framework for understanding the powerful new capacities of AI-related regulations.

Adaptive neural network surrogate model for solving the nonlinear elastic inverse problem via Bayesian inference
Authors: Huo Fuchang , Zhang Kai , Gao Yu , Li Jingzhi 
Published: March 2024

Abstract
In this paper, we consider a Bayesian method for nonlinear elastic inverse problems.
As a working model, we are interested in the inverse problem of restoring elastic properties from measured tissue displacement.
In order to reduce the computational cost, we will use the following multi-fidelity model approach. First, we construct a surrogate low-fidelity DNNs-based model in the prior distribution, then use a certain number of simulations of high fidelity model associated with an adaptive strategy online to update the low-fidelity model locally. Numerical examples show that the proposed method can solve nonlinear elastic inverse problems efficiently and accurately.
Computing the determinant of a signed graph
Authors: Alshamary Bader , Stanić Zoran 
Published: March 2024

Abstract
A signed graph is a simple graph in which every edge has a positive or negative sign. In this article, we employ several algebraic techniques to compute the determinant of a signed graph in terms of the spectrum of a vertex-deleted subgraph. Particular cases, including vertex-deleted subgraphs without repeated eigenvalues or singular vertex-deleted subgraphs are considered. As applications, an algorithm for the determinant of a signed graph with pendant edges is established, the determinant of a bicyclic graph and the determinant of a chain graph are computed. In the end, the uniqueness of the polynomial reconstruction for chain graphs is proved.
Automation of visual communication and aesthetic construction of national image: a computational aesthetic analysis of social bots on Twitter
Authors: Huang Yangkun , Chen Changfeng 
Published: March 2024

Abstract
Vision and aesthetics are inseparable dimensions of national image building. Based on 106,562 China-related images from Twitter (renamed as X), this paper introduced a computational aesthetic approach to investigate the visual communication activities of social bots on Twitter and compared the similarities and differences between human and bot accounts’ posted images so as to explore the influence of social bots’ aesthetic strategies. The results show that social bots have displayed different aesthetic strategies in the construction of the China-related visual frame, and formed obvious stylistic differences with humans in brightness, saturation, color, etc. Negative binomial regression indicates that the aesthetic strategies of social bots contribute to more likes and shares. The automation of visual communication and aesthetic construction not only makes the global building and communication of national image face new situations and challenges, but also pushes the whole human visual aesthetic, creation, and communication activities under the potential subjectivity crisis.
Candomblé in Public: How Religious Rites Become Civil Technologies in Salvador, Brazil
Authors: de Paula Leandro 
Published: March 2024

Abstract
In 2019, right before arriving in Salvador, Brazil, to develop missionary activities, an international Protestant organization declared that this city – the center of the black culture in the country – was “known for its people’s belief in spirits and demons.” The statement soon triggered indignation from activists and devotees of Candomblé, the Afro-Brazilian religion that is a key element of the city’s history and identity. This article analyzes the transformation of this case into a public problem, which demanded different forms of reparation and affirmation of religious differences. The text debates the extension of Candomblé's semiotic community in Salvador and how the circulation of its symbols in different social contexts furthers the dissolution of boundaries between “religion” and “politics.” I pursue such ideas by describing a form of civil protest that moves liturgical forms from the Candomblé temples to public spaces. Such civil protest technology engages music, dance, and a set of materialities, presenting an instructive performance of the constitution of “religion” and the “public” in a post-colonial landscape.
