Prognostic value of iron metabolism-related genes in bladder urothelial carcinoma
Authors: Lu Hezhen , Yue Siqi , Yang Zhaowei , He Chengyan , Pan Junqi
Published: May 2023

Objectives

Iron metabolism-related genes (IMRGs) play important roles in the prognostic assessment of many tumours. However, IMRGs have not been reported as prognostic biomarkers in bladder urothelial carcinoma (BLCA).

Methods

Gene expression profiles and clinical data from BLCA patients were obtained from The Cancer Genome Atlas (TCGA) database. We used the DESeq2 package to screen for differentially expressed genes (DEGs). The predictive values of the differentially expressed IMRGs in BLCA patients were further evaluated using univariate Cox regression analysis. The risk-scoring model was constructed using the least absolute shrinkage and selection operator (LASSO) algorithm. The performance of this model for predicting the prognosis of BLCA patients in TCGA-BLCA cohort was assessed using Kaplan–Meier (K–M) and receiver operating characteristic (ROC) curves. This risk-scoring model was combined with the clinicopathological characteristics of BLCA patients in a multiple regression analysis, and a nomogram was constructed using the independent predictors identified. ROC analysis and calibration curves were adapted to test the predictive ability of the nomogram. Gene set enrichment analysis (GSEA) was used to identify potential molecular pathways and processes enriched by differential expression genes between risk groups. Finally, we explored the ability of the risk-scoring model to assess immune cell infiltration levels through a correlation analysis.

Results

Fourteen identified IMRGs with prognostic value were incorporated into the risk-scoring model. The ROC and K–M survival curves indicated that the model could effectively predict the overall survival (OS) outcomes of BLCA patients. The multiple regression analysis revealed that the risk-scoring model could be used as an independent prognostic factor for BLCA patients, and the associated nomogram could effectively predict the OS outcomes of BLCA patients. GSEA revealed that the DEGs between the risk groups were mainly involved in biological processes such as developmental process, cell cycle, mitosis, RHO GTPase reaction, DNA repair, and extracellular matrix regulation. The immune infiltration analysis showed that the infiltration levels of immune cells such as natural killer cells, memory T cells, effector T cells, Th2 cells, and macrophages differed significantly between the risk groups.

Conclusions

IMRGs screening revealed prognosis-associated genes. The prognostic model constructed could effectively predict the prognosis of BLCA patients, and the identified genes represent potential targets for BLCA treatment.
Managing the Vague: John Dewey’s Aesthetics and the Relation of Fine Art and Mathematics
Authors: Ruoppa Raine
Published: May 2023

In philosophical discourse, vagueness is commonly regarded as an undesirable and problematic aspect of human experience. Such standpoints are not unfounded. However, in this article, I argue that vagueness may in certain instances also possess an instrumental role that supports specific modes of human aspiration, including the artistic and the mathematical. In particular, I investigate the ways in which vagueness not only hinders but also fosters the emergence of an aesthetic quality of experience during the imaginative endeavours of fine art and mathematics. The manner in which the benefit from felt vagueness ties into the formation of artistic and mathematical scenarios helps to illuminate deep and often unnoticed relations between these two domains of human ingenuity. In this article, the overall concept of experience and the particular features of human experience, such as the aesthetic and the vague, are examined in the context of John Dewey’s philosophical pragmatism. In Dewey’s philosophical framework, the human mind and culture are understood as natural phenomena. As such, the Deweyan approach fits the paradigm of a twenty-first century scientific understanding of the inherent ontological unity of all modes of human existence and activity.
Women and the Ballad Trade in Eighteenth-Century England
Authors: Atkinson David
Published: May 2023

Knowing that women sold ballads in the eighteenth-century streets it is but a small step to imagining them as characters out of Hogarth’s engravings, impoverished, debased, or defiant. No doubt there is some truth in that characterization, but overall the variety of women’s experiences in the ballad trade was very much broader than this. While a good deal of attention has been paid to the women’s contributions to the eighteenth-century book trade, comments specifically concerning the ballad trade have been fairly superficial, with the exception of Paula McDowell’s studies of some individual women early in the century (cited below). This paper presents some evidence for the different ways in which women were involved with the ballad trade, paying attention to their economic role, and interrogating some contemporary visual and literary representations of ballad women.
The (Im)Possibility of Academic Integrity in John Williams’s Stoner
Authors: Matek Ljubica , Rehlicki Jasna Poljak
Published: May 2023

Written in 1965, Stoner, the recently re-discovered academic novel by John Williams (1922-1994) deals with a variety of intriguing issues such as the role of literature in the personal growth of an individual, the tension between private desires and social customs, and the role of family in an individual’s life.1 By some, it was read as “an all-American success story …[about] socio-economic mobility through hard work, individual effort, and merit” (Wald 2). Our paper, however, will focus on the portrayal of issues such as academic integrity and the perception of academics and academic work. Williams’s novel, not only through the story it tells, but also as an object, as a work of art, seems to reflect on the worrying idea of the irrelevance of the humanities, the humanist way of thinking, and humanist preoccupations, and does this in a way that is rather untypical of most campus novels.
Crisis and Literature: Future Imperfect, or the Case of Don DeLillo’s Cosmopolis
Authors: Sári B. László
Published: May 2023

In his afterword to The Cambridge Companion to Don DeLillo (2008), Joseph M. Comte makes a strong case for positioning the author as a writer of historical liminality, and citing DeLillo himself, he claims that Cosmopolis is a text “poised liminally ‘between the end of the Cold War and the beginning of the Age of Terror’” (183). Not yet aware of the shift taking place in the author’s interest from all matters historical to his previous preoccupation with corporeality and writing, Comte goes on to argue that DeLillo’s novel of 2003 stages how “[c]yber-capital and terrorism contend within the singularity of global power” (185), inasmuch as the text is preoccupied with what commentators usually identify as “the technological sublime” (186) in DeLillo’s oeuvre, in this case representing the “interaction between technology and capital, the inseparability” of the two (23). Comte and other scholarly commentators praise Cosmopolis exactly for what it was criticized for at the time of its publication, its witty handling of academically embedded ideas, thereby somewhat downplaying how the text, as I will argue, discusses, or indeed embodies, some of these ideas in relation to the white male body and terrorism in a curious temporal structure: written after 9/11, but presenting what one may call reverse déjà vu of the terror attacks. Comte’s estimation is, therefore, in line with the contemporary reviews of the book at the time of its publication, and stresses the intellectual achievement and poetic qualities of the text.
Legacies of the Past and the American Family: Sam Shepard’s True West and Suzan-Lori Parks’s Topdog /Underdog
Authors: Németh Lenke
Published: May 2023

Isolation from societal and historical continuity ingrained in American thought and culture has resulted in an unprecedented economic growth, creativity, and flexibility in all facets of American life. Paradoxically, a constant search for an American past—generated by the lack of a common history—also prevails in American culture and these mutually exclusive trends lead to a sense of “rootlessness, loss of connections, and anxiety about identity” (Menides 607). American literary expressiveness appears to reflect these opposing views on history as well as the impact these attitudes exert on the (in)stability of the American character. Viewed from the “classic” period of American literature a variety of responses were generated by the literary culture. American writers’ approaches to history range from evident separation from the constraints and restraints of history and tradition (Emerson, Thoreau) through creating romanticized versions of the American past (Cooper, Longfellow) to the search of a “usable past”2 (Eliot, Pound) that would explain the causes and impinge on the way how Americans exist in the present (Menides 607).
James Christopher O’Flynn and The Cork Shakespearean Company
Authors: Kavanagh Annetta
Published: May 2023

In Ireland, the period between 1891-1922 known as the Revival, was a curious mix of political agitation and frenetic literary, linguistic, and musical activity which shaped modern Irish culture. It was a time when new synergies were manifested linking artistic ventures with nationalist sentiment. Cork was at the centre of this febrile revolutionary activity. The Rev James Christopher O’Flynn (hereafter referred to as O’Flynn), moved in circles close to key political, intellectual, and artistic fi gures who helped forge the new state. He is, however, largely unknown. Despite his huge contribution to the movement, he turned his back on the spirit of the Revival and turned instead to producing the works of Shakespeare. His theatre company, The Cork Shakespearean Company, remains the longest running amateur Shakespearean company in the world. What is perhaps even more extraordinary is that for its first decade, the Cork Shakespearean Company was comprised almost entirely of working-class players.
Application of a sustainable destination framework to model Mexican heritage destination resilience in times of crisis
Authors: Heald Jeremy
Published: May 2023

The article discusses World Heritage Site Guanajuato, Mexico, a mature destination which suffers sustainability issues concerning water provision, traffic congestion, and refuse collection, the result of chaotic urban growth. Stagnating visitor numbers indicates ageing social infrastructure, dated tourism products, and reputational damage of public insecurity. The research objective is to improve municipal planning by using a resilience framework from the tourism ecology literature to encourage sustainable development. It integrates the results of a 2021 survey of local tourism business opinion and finds Guanajuato’s multi-business owners are innovative in crisis, reacting to covid-19 with changes to their products and services. Federal and State government hardly responded. It should widen membership of the municipal Tourist Board and incorporate project evaluators within the local Planning Office to apply a resilience model to address environmental, infrastructural, and tourism challenges.

Aproximações entre bioma pampa e ecofeminismo desde a educação ambiental crítica
Authors: Behling Greici Maia
Published: May 2023

A Educação Ambiental Crítica tende a perceber que os problemas ambientais contemporâneos não encontram respostas em soluções disciplinares e reducionistas. Desta forma, compreende que os processos de exploração do bioma Pampa estão assentados em questões construídas socialmente, a partir de um sistema de dominação e opressão da natureza. Nesse sentido, compreende-se que a dominação da natureza está inter-relacionada com o patriarcado e a dominação do feminino. Assim, este artigo objetivou tecer pontos de convergência entre o bioma Pampa e o ecofeminismo, diante do olhar da educação ambiental crítica.Palavras-chave: Educação ambiental crítica. Ecofeminismo. Bioma Pampa.Approximations between the Pampa biome and Ecofeminism from Critical Environmental EducationAbstract:Critical Environmental Education tends to acknowledge that contemporary environmental problems do not respond well to disciplinary and reductionist solutions. We find that the processes of exploration of the Pampa biome are based on socially constructed issues which arise from a system that dominates and oppresses nature. Therefore, we comprehend that the domination of nature is interrelated with patriarchy and the domination of the feminine. Thus, this article seeks to reveal points of convergence between the pampa biome and ecofeminism from the perspective of critical environmental education.Keywords: Critical environmental education.

Three scholars share their pandemic experiences, weaving narrative and poetry in an anti-anti-narrative of illness, death, stress, and fear. This is a tale of relentless living at a distance—of the drip, drip, drip, drip, drip, minute by minute, year after year, endless cascade of unresolved anxiety and the shared cortisol spike so many of us have endured slogging through the interminable pandemic in a death-indifferent culture.
Russia Remembered
Authors: Giorgio Grace
Published: May 2023

This autoethnography is about the author’s arranged marriage to a Jewish, Soviet scientist, a transaction meant to release him and his family from their home country at a time when leaving for Jews was nearly impossible. Arranged marriages offered possibility but brought subjective complexities over the ethical and even safety concerns to those involved. Drawing from the author’s journals, this story foregrounds subjective connection to these ethical concerns. While this story is the author’s (and Misha’s, a pseudonym), it captures the human story of finding humanity in those we disagree with, those we find difficult, those we want to reject, including maybe especially ourselves.
Consonance Dissonance and Cadences
Authors: Granot Roni , Maimon Neta B.
Published: May 2023

The musical surrounding typical of most non-European/North American population includes some mix of Western, local art or folk music, and hybrid forms combining the two. How do these various musical systems play out in the internalized musical mental schemes of their listeners? Have Western musical schemes been totally internalized in such populations? Here we ask this question in relation to Israeli Arabs (IAs)—one group within the highly understudied Arab musical world. Specifically, we compared the responses of 52 IAs and 34 Israeli Jews (IJs) to 11 harmonic dyads based on intervals from the musical systems of both cultures, and to a harmonic cadence that ended with chords representing five degrees of closure. Both studies show differences between the two groups with the IJs showing typical response patterns of Western listeners, and the IAs showing much less differentiation and only a partial internalization of tonal hierarchies; namely, the differentiation between in-scale and out-of-scale tones. We emphasize that the listening habits of the selected populations should be mapped more consistently in order to understand the statistical regularities in the relevant repertoires. We also point to the need to adjust our experimental materials and methods to better suit these populations.
Mineralocorticoid receptor knockout in Schwann cells alters myelin sheath thickness

Published: May 2023

Myelination allows fast and synchronized nerve influxes and is provided by Schwann cells (SCs) in the peripheral nervous system. Glucocorticoid hormones are major regulators of stress, metabolism and immunity affecting all tissues. They act by binding to two receptors, the low-affinity glucocorticoid receptor (GR) and the high-affinity mineralocorticoid receptor (MR). Little is known about the effect of glucocorticoid hormones on the PNS, and this study focuses on deciphering the role of MR in peripheral myelination. In this work, the presence of a functional MR in SCs is demonstrated and the expression of MR protein in mouse sciatic nerve SC is evidenced. Besides, knockout of MR in SC (SCMRKO using Cre-lox system with DesertHedgeHog (Dhh) Cre promoter) was undertaken in mice. SCMRKO was not associated with alterations of performance in motor behavioral tests on 2- to 6-month-old male mice compared to their controls. No obvious modifications of myelin gene expression or MR signaling gene expression were observed in the SCMRKO sciatic nerves. Nevertheless, Gr transcript and GR protein amounts were significantly increased in SCMRKO nerves compared to controls, suggesting a possible compensatory effect. Besides, an increase in myelin sheath thickness was noted for axons with perimeters larger than 15 µm in SCMRKO illustrated by a significant 4.5% reduction in g-ratio (axon perimeter/myelin sheath perimeter). Thus, we defined MR as a new player in peripheral system myelination and in SC homeostasis.

La barbarie o las grietas de lo porvenir
Authors: Aguirre Moreno Arturo
Published: May 2023

Por sus alteraciones y sus datos manifiestos es un hecho: estamos en el “tiempo de barbarie”; una barbarie que no se restringe al fenómeno de la ferocidad y la violencia extrema, sino que repercute en la interioridad y el ahínco constante desorientación de la racionalidad en los individuos y las comunidades contemporáneos. Esto obliga a pensar, no sólo desde una filosofía de la cultura, antes bien, partir desde una “filosofía de la barbarie” que la teoría actual ha desarrollado en sus más insignes representantes, trastocando sus propias categorías y repensando el porvenir del hombre en sus dinámicas simbólicas. Hacer frente con la entereza de una razón que no decline ante las adversidades, parece ser la tarea más fundamental de nuestros días. Aquí ensayamos ese camino.

La rehabilitación de pavimentos deteriorados requiere de diversos recursos tanto naturales como económicos. Ante tal problemática, esta investigación tuvo como objetivo elaborar un diseño de mezcla para la estabilización de un suelo reciclado con emulsión asfáltica tipo CSS-1h, utilizando el método de diseño Marshall modificado. El estudio analizó la influencia del porcentaje de emulsión asfáltica (3,0 % a 6,0 %) respecto a las propiedades físicas y mecánicas del suelo estabilizado según los parámetros que exige el manual peruano de carreteras EG-2013.
Los resultados muestran que, con una dosificación de 4,8 % de emulsión asfáltica y 2,88 % de residuo asfáltico se logra el mejor comportamiento en comparación a los demás porcentajes planteados, obteniendo una máxima estabilidad de 980 kg superando el mínimo valor de 227 kg establecido por la norma. Se concluyó que con dicha dosificación se obtiene una mezcla asfáltica estable con la que se puede estabilizar el pavimento deteriorado para soportar un tránsito vehicular mediano.

Jovens organizados, mas não participativos: análise de um movimento social da Metrópole
Authors: Candido João Gremmelmaier , Alves Luiz Roberto , Vieira Almir Martins
Published: May 2023

O lugar da juventude no contexto das políticas públicas brasileiras tornou-se assunto recorrente no cenário acadêmico a partir do ano 2000. Em estudos recentes, há razoável consenso de que os jovens constituem o grupo etário mais desfavorecido no tocante às condições restritivas de emprego, situação decorrente da precarização do trabalho jovem e o decorrente abandono dos estudos, ou seja, a linha de tensão entre permanência na escola e inserção no mercado de trabalho. Assim, este trabalho tem por objetivo analisar uma organização não governamental da sociedade civil formada por jovens munícipes da região metropolitana do grande ABC paulista (Brasil). O campo teórico toma por base o conceito de minorias ativas, levando em conta a obra de Cohn-Bendit, além das propostas de políticas públicas para a juventude, defendidas por Sposito. Trata-se de pesquisa concluída, cujo percurso metodológico assumido contemplou um estudo de caso, referendado por abordagem qualitativa, nos moldes de Denzin e Lincoln, bem como indicações de Gonzales-Rey. Os dados foram coletados por meio de entrevistas junto aos jovens participantes do movimento, observação não participante realizada na sede da organização e análise documental do estatuto social da organização. Os resultados mostraram que, apesar da existência do movimento se pautar na relação com o poder público municipal, boa parte da população jovem pertencente ao município se mostra alheia ao que acontece na cidade, seja por falta de informação ou até mesmo por falta de interesse. Evidenciou-se também que a prioridade reside em questões sobre trabalho e renda, ficando as demais (como participação na construção de espaços públicos, por exemplo) relegadas a segundo plano. Constatou-se, de maneira geral, que os jovens possuem iniciativa e preparo para se organizar, porém pouca maturidade e interesse em se engajar. Assim, a articulação em prol de demandas coletivas fragiliza-se em razão da limitada noção de políticas públicas para a juventude. Ou seja, manifesta-se uma minoria “pouco ativa”, embora organizada. Ainda que tenha sido desenvolvido estudo de caso único, provavelmente o panorama descrito seja realidade em outros movimentos sociais semelhantes na metrópole e até mesmo no país (Brasil), embora estudos de ordem qualitativa são restritos em termos de generalização. Recomenda-se, para estudos futuros, investigações junto a outros movimentos sociais compostos por jovens (como o movimento estudantil, por exemplo), com o objetivo de analisar possíveis relações entre a postura dos jovens e os valores culturais brasileiros.

Published: May 2023

In recent years, accelerated bridge construction has led to the substantial application of precast post-tensioned segmental (PPS) bridge piers. However, PPS piers are not widely used in high-seismicity regions due to their low energy-dissipation capacity (EDC). To address this deficiency, a series of shape memory alloy (SMA)–concrete composite PPS piers were examined in this work. Non-linear static and dynamic analyses were performed on experimentally validated finite-element models of the SMA–concrete composite piers and the results were compared with those of piers without SMA bars. It was found that the length, area and post-tensioning ratio of the SMA bars affected the EDC of the piers, and an optimal design of the bars is required to reach the highest EDC possible. The effects of SMA bars on the frequency response functions of piers were investigated for the first time in this study and it was found that, unlike the piers without SMA bars, sub-harmonics and super-harmonics were not seen in the responses of the SMA–concrete composite piers, mainly the drift responses. Furthermore, the SMA–concrete composite piers experienced a significant reduction in drift responses compared with piers without SMA bars.

To ensure safe and reliable operation of pipeline systems, it is necessary to regularly carry out work on technical diagnostics. Ultrasonic inspection is one of the most common methods for pipeline technical condition determining. It has many advantages over other control methods among which there can be distinguished accessibility, the absence of additional requirements for equipping the object under examination, the absence of an impact on the object of control itself, and safety. But ultrasonic inspection also has disadvantages some of which can be eliminated by using an individual piezo elements of multi-element transducer instead of simple single-element transducers.

The method of pipeline wall thickness determining using  piezo elements of a multi-element transducer, as well as searching for and identifying the type and size of the defect, is known as ultrasonic tomography.

This paper presents the main features of the transducers used in ultrasonic tomography, possibilities of ultrasonic tomography when it is used in field pipeline diagnostics. The advantages of using the method of ultrasonic tomography in comparison with conventional ultrasonic control are considered.

Authors: Zakharov S. V. , Lushpey V. P. , Ibragimova A. V. , Fengwei Liu , Bowen Ma
Published: May 2023

The article discusses the processes of soil pollution by oil hydrocarbons in conditions of lens and permafrost. The authors use the methods of mathematical modeling, methods of experimental observations, comparative analysis. The risks of leaks and spills of oil hydrocarbons are indicated as an extremely important issue requiring study using various methods. Brief reviews of the results of studies of soil pollution by oil hydrocarbons are given. A brief analysis of the dynamics of soil pollution by oil hydrocarbons is presented. A hypothesis has been put forward that, when stability is disturbed in lens permafrost, the dynamics of pollutant distribution differs significantly from the dynamics of their distribution under normal conditions. Photographs, drawings, schemes of the distribution of pollutants within the lens and permafrost formations are given. The results of the initial modeling of the spreading of oil hydrocarbons within permafrost lens formations are presented. The process of modeling soil pollution with oil products in conditions of lens permafrost is divided into two stages: the primary modeling of pollution of the permafrost lens itself and the model of the secondary process, when pollutants bypass lens permafrost in the process of diffusion and enter non-frozen soil. The model involves the calculation of areas – pollution halos, as well as the calculation of the surface concentration of pollutants in them. It is concluded that the composition of oil sludge formed with the participation of pollutants is determined by many factors – climatic, physical and chemical, characteristics and composition of the soil. It is concluded that, due to climatic conditions and the state of island (lens) permafrost, the pollution process can differ significantly in dynamics.

Main Approaches to «Public Power» Definition in Public Law (State Law) Doctrines
Authors: Pilia D. E.
Published: May 2023

The paper is devoted to examination of the main approaches to the definition of the concept of «public power» that has developed in the theory of state and law, in constitutional and administrative law. The analysis of theoretical and legal views allowed the author to conclude that public power in the theory of state and law is defined as an institutionalized legal social power supported by the force of coercion and exercised within a certain territory or social community. General theoretical conclusions and provisions have been developed in public law (state law) studies. The Russian theory of constitutional law is dominated by the concept of public power as the people’s power, according to which all power in the Russian Federation belongs to its multinational people. In addition, in constitutional law, a systematic approach to the definition of the concept of «public power» is widespread. As a rule, the systematic approach distinguishes three types (forms, levels) of public power: direct public power (direct democracy, public power), state power, municipal power. In administrative law, the research of public power has not been as widespread as in constitutional law. At the same time, the analysis of scientific sources allowed the author to single out institutional (public power is viewed through the prism of government bodies) and functional (public power as a set of functions and powers of government bodies and organizations endowed with state authority) approaches as the main approaches. The author concludes that regardless of the initial positions used by various public law doctrines the basic properties of public power include legitimacy, complexity, institutionality, functionality.
Earthquake Detection with tinyML
Authors: Clements Timothy
Published: May 2023

Earthquake detection is the critical first step in earthquake early warning (EEW) systems. For robust EEW systems, detection accuracy, detection latency, and sensor density are critical to providing real-time earthquake alerts. Traditional EEW systems use fixed sensor networks or, more recently, networks of mobile phones equipped with microelectromechanical systems (MEMS) accelerometers. Internet of things edge devices, with built-in tiny machine learning (tinyML) capable microcontrollers, and always-on, internet-connected, stationary MEMS accelerometers provide the opportunity to deploy ML-based earthquake detection and warning using a single-station approach at a global scale. Here, I test and evaluate tinyML deep learning algorithms for earthquake detection on a microcontroller. I show that the tinyML earthquake detection models can generalize to earthquakes outside the training set.

Authors: Giri Richa , Singh Vinay P. , Gulati Yuvraj , Kumar Vinay
Published: May 2023

Background: Chronic liver disease (CLD) is a continuous process of inflammation, destruction, and regeneration of liver parenchyma, which leads to fibrosis and cirrhosis. Liver plays an essential physiological role in thyroid hormone activation and inactivation, transport, and metabolism, as well as the synthesis of thyroid binding globulin. A complex relationship exists between thyroid and liver in health and disease.
Methods: 103 patients of CLD were included in this study from December 2020 to September 2022. They were classified as per child Pugh scoring after clinical assessment and investigations. Serum TSH, FT3, FT4 levels were measured for all the patients.
Results: Out of 103 patients and it was found that 19 (18.44%) patients belonged CTP class A, 40 (38.83%) patients had CTP score of class B, while maximum 44 (42.71%) patients belonged CTP class C. There was significant positive correlation between CTP class and TSH values (p<0.001) with mean (SD) of CTP class A, B and C were 2.42 (0.76), 3.9 (1.02) and 5.91 (1.08) respectively. There was significant negative correlation between CTP class and FT3 values (p<0.001) and between CTP class and FT4 values (p<0.001).
Conclusions: Our study found that there was significant positive correlation of S.TSH values with severity of CLD as assessed by CTP score, while FT3 and FT4 were having significant negative correlation.
