Fast and accurate computation of polar harmonic Fourier moments for image description
Authors: Yang Siyu , Deng Ansheng
Published: July 2023

Continuous orthogonal moments are widely used in various image techniques due to their simplicity and good rotational invariance and stability. In recent years, numerous excellent continuous orthogonal moments have been developed, among which polar harmonic Fourier moments (PHFMs) exhibit strong image description capabilities. However, the numerical integration error is large in the calculation, which seriously affects the calculation accuracy, especially in higher-order calculation. In this paper, a continuous orthogonal moments-fast and accurate PHFM (FAPHFM) is proposed. It utilizes the polar pixel tiling technique to reduce numerical errors in the computation; this method particularly improves the accuracy of higher-order moments of traditional PHFMs. However, as accuracy increases, calculation complexity also increases. To address this issue, an eight-way symmetric/anti-symmetric calculation of the angular and radial functions was performed using the symmetry and anti-symmetry of traditional PHFMs, and clustering of pixels was performed as a way to improve the computational speed. The experimental results show that FAPHFMs perform better in image reconstruction (including noise), with higher computational accuracy, lower time complexity, and better image description ability.

Published: July 2023

The current recommendation obligates children to receive all vaccines within two years of birth. The Expanded Program on Immunization (EPI) was established in Ethiopia to increase the immunization rate by 10% annually and to reach 100% in 10 years but not been achieved in twenty years. Missed opportunity for vaccination (MOV) is one of the major factors in vaccination coverage. Hence, this study aimed to assess the prevalence of MOV and associated factors in Jimma Town public health facilities. A facility-based cross-sectional study design was employed with a quantitative data collection method. The sample size was calculated using a single population proportion formula. The data were collected through face-to-face interviews, and data extraction methods and analyzed using SPSS version 26. The statistical association was decided at p-value <0.05 with 95% CI, and AOR. A total of 422 children were involved in this study making a 100% response rate. The magnitude of MOV was 39.8% (95%CI: 35–45). Parents/caretakers have not attended formal education (AOR = 4.65, CI:1.64–13.24), residing in rural (AOR = 2.60, CI: 1.35–5.03), poor knowledge about immunization (AOR = 2.61, CI: 1.58–4.30), the child not assessed for vaccination status (AOR = 3.01, CI: 1.65–5.49), and parents/caretakers not seen/heard vaccination message in the last month (AOR = 2.42, CI: 1.40–4.18) were statistically positively associated with the MOV. In conclusion, this study indicated that MOV among the children was high in the study facilities. The researchers recommended stakeholders work on strengthening community awareness creation. Additionally, further study incorporating physician-related factors is also suggested.
Cross-checking journalistic fact-checkers: The role of sampling and scaling in interpreting false and misleading statements
Authors: Markowitz David M. , Levine Timothy R. , Serota Kim B. , Moore Alivia D.
Published: July 2023

Professional fact-checkers and fact-checking organizations provide a critical public service. Skeptics of modern media, however, often question the accuracy and objectivity of fact-checkers. The current study assessed agreement among two independent fact-checkers, The Washington Post and PolitiFact, regarding the false and misleading statements of then President Donald J. Trump. Differences in statement selection and deceptiveness scaling were investigated. The Washington Post checked PolitiFact fact-checks 77.4% of the time (22.6% selection disagreement). Moderate agreement was observed for deceptiveness scaling. Nearly complete agreement was observed for bottom-line attributed veracity. Additional cross-checking with other sources (Snopes, FactCheck.org), original sources, and with fact-checking for the first 100 days of President Joe Biden’s administration were inconsistent with potential ideology effects. Our evidence suggests fact-checking is a difficult enterprise, there is considerable variability between fact-checkers in the raw number of statements that are checked, and finally, selection and scaling account for apparent discrepancies among fact-checkers.
Point Cloud Reconstruction From Truncated Geometry-Based Streams
Authors: Garcia Diogo C. , Souto Andre L. , Sandri Gustavo P. , Borges Tomas M. , de Queiroz Ricardo L.
Published: July 2023

Geometry-based point cloud compression (G-PCC) has been rapidly evolving in the context of international standards. Despite the inherent scalability of octree-based geometry description, current G-PCC attribute compression techniques prevent full scalability for compressed point clouds. In this paper, we present a solution to add scalability to attributes compressed using the region-adaptive hierarchical transform (RAHT), enabling the reconstruction of the point cloud using only a portion of the original bitstream. Without the full geometry information, one cannot compute the weights in which the RAHT relies on to calculate its coefficients for further levels of detail. In order to overcome this problem, we propose a linear relationship approximation relating the downsampled point cloud to the truncated inverse RAHT coefficients at that same level. The linear relationship parameters are sent as side information. After truncating the bitstream at a point corresponding to a given octree level, we can, then, recreate the attributes at that level. Tests were carried out and results attest the good approximation quality of the proposed technique.
Topicality of John Stuart Mill’s Views on Violence against Women
Authors: Filipow Elżbieta
Published: July 2023

In the paper, I show that John Stuart Mill in his work noticed the significance of the social problem posed by violence against women. To achieve that goal, I (1) sketch the theoretical background of his philosophy as a reference point for the issue of violence against women; (2) propose reading The Subjection of Women in a way that is to facilitate noticing the most important issues of violence and showing their topicality in today’s world; and (3) provide several most significant examples of problems of violence against women that should be given some further reckoning. Thus, I prove that Mill’s views on violence against women are up to date, and remain an important point of reference, making him still worth reading, even 150 years after his death.

Authors: Lendvai László , Rigotti Daniele
Published: July 2023

The present study aims at investigating the effect of hexagonal boron nitride (hBN) nanoplatelets on the properties of acrylonitrile butadiene styrene (ABS) polymer. Composites containing 0-30 vol% hBN were prepared through batchwise melt compounding, which was followed by compression molding. Subsequently, the thermal and thermomechanical properties of the fabricated samples were investigated. The dynamic mechanical analysis (DMA) revealed that the storage modulus of the samples was markedly improved in the entire examined temperature range, while the glass transition temperature also gradually increased as a function of hBN content. According to the thermogravimetric analysis (TGA), the incorporated boron nitride particles enhanced the thermal stability of ABS composites, exhibiting a notably higher decomposition onset temperature. Additionally, the thermal conductivity of the ABS/hBN composites significantly increased by 570% when the hBN content was 30 vol%.

Authors: Chattopadhyay Anindita , Majumdar Angshuman , Gangopadhyay Sankar
Published: July 2023

With the help of ABCD matrix concept, we examine the coupling efficiency of a single mode circular core graded index fiber (GIF) excited by laser diode via cylindrical micro lens on the fiber tip. We investigate the efficiencies for refractive index distribution of some specific profile exponents such as g = 4.0, 8.0, 10.0 and 20.0. The refractive index distribution for GIFs had been studied earlier. The efficiency is calculated along the vertical plane as the efficiency is very poor along the horizontal plane. For two very common wavelengths 1.3 μm and 1.5 μm the efficiencies have been calculated and for 1.3 μm wavelength the refractive index distribution of profile exponent (g) having the value g = 4 is found to be most efficient in this context. The results are very much important in the design of optical optimization.
Design mode filtering interferometer using etched double clad fiber
Authors: Khamees Mohanad G. , Mansour Tahreer S.
Published: July 2023

Mode filtering technique is one of the most desired techniques in optical fiber communication systems, especially for multiple input multiple output (MIMO) coherent optical communications that have mode-dependent losses in communication channels. In this work, a special type of optical fiber sensing head was used, where it utilizes DCF13 that is made by Thorlabs and has two numerical apertures (NA’s). One is for core and 1st cladding region, while the 2nd relates the 1st cladding to the 2nd cladding. Etching process using 40 % hydro-fluoric (HF) acid was performed on the DCF13 with variable time in minutes. Investigation of the correlation between the degree of etching and the refractive index (RI) profile of double-clad fibers for low order linearly polarized (LP) modes is the focus of this work research. The used software programs to simulate the effect of etching are Comsol Multi-Physics V6 and Optigrating V4.2.2. It is seen that the optimum case that gave highest cladding power to core power ratio is the case of etching for 10 min, which can be used for detection applications. This ratio greatly affects the sensitivity of the system.

Published: July 2023

Optical fibers are a key inventive discovery that contributed to the digital revolution, although cost becomes a major factor for long-distance communication. Whereas passive optical networks (PONs) offer reduced costs and cater to multiple users; hence, they are becoming more common in LANs, densely inhabited areas, and backbone networks. Numerous experiments on PON systems have been authored in the last couple of years, with results expressed in terms of BER, eye openings, quality of received bits factor, signal-to-noise ratio (SNR), and burst blocking, which demands a vast review of PONs based on these parameters. So, a comprehensive review of PONs is extensively researched to identify the methods’ limitations. Along with long-reach(LR)-PON systems, power conservation in PONs and burst contention are also addressed. To demonstrate the performance of PON architectures, the findings are provided in terms of delay, energy efficiency, and operations intensity.
Distortion managed directly modulated on-off keying signal transmission for 10 Gbps visible light communications using electrical filtration
Authors: Sudhakar Muppidi Venkata , Rajini Gaddam Kesava Reddy
Published: July 2023

In this research, a communication system that uses visible light as a carrier and is designed for high-throughput interior applications. In order to lower the overall system cost, this work uses intensity modulation at the transmitter and direct detection with electrical filtering at the receiver. Various low-pass filtration techniques (Gaussian, Butterworth, Bessel, and Chebyshev) have been proposed in his paper to mitigate the effect of channel distortion in visible light communication (VLC) systems. The achieved transmission range is up to 3 m in addition to the supported data rate of 10 Gbps with a bit error rate of less than 10−9. Simulations are carried out using optisystem software that includes PRBS OOK optical signal generation at LED output in the transmitter, VLC channel, and APD with LPF in the receiver.

Authors: Fotiadou Anatoli , Achilleos Orthodoxos , Picard Jean-Yves , Lamprinou Zoe , Passalides Alexandros , Vlachopapadopoulou Elpis-Athina
Published: July 2023

Objectives

To highlight important clinical aspects of Persistent Müllerian duct syndrome (PMDS). PMDS belongs to the group of differences of sex development. It is attributed to mutations in genes encoding for the anti-Müllerian hormone or its type II receptor (AMHR2) and inherited via an autosomal recessive transmission.

Case presentation

An 18-day-old male infant with known bilateral cryptorchidism, presented with left-sided obstructed inguinal hernia. The diagnosis of PMDS was considered during inguinal exploration as both testes together with uterus and fallopian tubes were recognized in the hernial sac. Histology confirmed the presence of Müllerian-derived tissues. Genetic testing revealed two different mutations of the AMHR2 gene, both with autosomal recessive transmission: a frequently encountered deletion of 27 pairs bases on exon 10 of this 11 exon gene and a novel deletion of 2 pairs bases on exon 6.

Conclusions

This case is notable being the rarest type of PMDS, that of transverse testicular ectopia and associated with a novel AMHR2 gene mutation.
Navigating liminal spaces together: a qualitative metasynthesis of youth and parent experiences of healthcare transition
Authors: South Katherine , DeForge Christine , Celona Carol Anne , Smaldone Arlene , George Maureen
Published: July 2023

Transition from pediatric to adult care for adolescents and young adults (AYAs) with chronic illness affects the entire family. However, little research has compared AYA and parent experiences of transition. Using Sandelowski and Barroso’s method, the aim of this metasynthesis was to summarize findings of qualitative studies focusing on the transition experiences of AYAs and their parents across different chronic physical illnesses. PubMed, EMBASE and CINAHL were searched followed by forward and backward citation searching. Two authors completed a two-step screening process. Quality was appraised using Guba’s criteria for qualitative rigor. Study characteristics and second order constructs were extracted by two authors and an iterative codebook guided coding and data synthesis. Of 1,644 records identified, 63 studies met inclusion criteria and reflect data from 1,106 AYAs and 397 parents across 18 diagnoses. Three themes were synthesized: transition is dynamic and experienced differently (differing perceptions of role change and growth during emerging adulthood), need for a supported and gradual transition (transition preparation and the factors which influence it) and liminal space (feeling stuck between pediatric and adult care). While AYAs and parents experience some aspects of transition differently, themes were similar across chronic illnesses which supports the development of disease agnostic transition preparation interventions. Transition preparation should support shifting family roles and responsibilities and offer interventions which align with AYA and family preferences.
Fine-tuning biexcitons-plasmon coherent states in a single nanocavity

Published: July 2023

A tunable plexcitonic material that sustains multimode hybridization is highly desirable, which is vital for advanced quantum devices. However, the research about regulations of biexcitons-plasmon coherent states has rarely been reported. Here we apply single-nanoparticle scattering spectroscopy correlative with SEM imaging to identify biexcitons-plasmon interaction in a metal-semiconductor hybrid structure composed of a single Au@Ag nanoparticle, J-aggregates molecules and tungsten disulfide (WS2) monolayer. The mode competition within the localized plasmonic hotspots (∼240 nm3) is revealed by continuously regulating the J-aggregates spacer. Two distinct anticrossings are observed at both excitons resonances, and large double Rabi splittings (137 meV and 124 meV) are obtained successfully. We establish experimentally that J-aggregates and WS2 monolayer are responsible for the middle polariton states, while plasmon rarely contributes. Further calculations show that plasmonic nanocavity enables coherent energy exchange with different excitons by providing a highly enhanced localized E-field. In addition, we find that the multimode coupling strengths can be efficiently tuned by changing the cavity morphology and environment temperature, where the tuning spectral accuracy can reach up to 1 nm. Our findings uncover the distinctive properties of biexcitons-plasmon polaritons, suggest an easily obtainable multiqubit states platform, and open up a new way to construct nanoscale photonic devices.

Authors: Balachandran Rogini , Sørensen Mette Møller , Funder Jonas Amstrup , Knudsen Anders Riegels , Iversen Lene Hjerrild
Published: July 2023

Objectives

Peritoneal metastases (PM) and liver metastases (LM) are present simultaneously in up to 2 % of patients at the time of their colorectal cancer (CRC) diagnosis. Curatively intended treatment includes cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) combined with LM resection. A less invasive treatment for LM is ablation. We aimed to estimate overall survival (OS), disease-free survival (DFS) and postoperative data in patients managed simultaneously with CRS, HIPEC and radiofrequency ablation (RFA) as first choice.

Methods

This was a retrospective national cohort study. All patients were treated at Aarhus University Hospital; the only CRS+HIPEC centre in Denmark. We included CRC patients managed with curative intent for simultaneously diagnosed PM and LM in the period January 2016 – December 2021. LM was treated with RFA as first choice, if possible. Survival was calculated by the Kaplan-Meier method.

Results

A total of 25 patients were included, the median age was 60 years (range 43–75 years) and 15 (60 %) were females. The median peritoneal cancer index was 7 (range 0–12), the median number of LM was 1 (range 1–3). Ablation was performed as the only treatment for LM in 18 (72 %) patients. After a median follow-up time of 17.1 months (range 4–36 months), the median OS was 28.6 months (95 % confidence interval (Cl) 15.8;36.1), 1-year OS was 84.0 % (95 % Cl 62.8;93.7). Median DFS was 6.1 months (95 % Cl 4.0;10.3). Median LOS was ten days (range 5–26 days). Both 30-day and 90-day mortality were 0 %.

Conclusions

The selected treatment modality (RFA) for CRC patients with both LM and PM was safe. However, DFS was low. Further research is warranted to investigate if RFA is as effective as LM resection.

Functional foods, drug delivery systems, and cosmetics are the main areas of application for multiphase systems, where the use of naturally derived compounds is preferred. Hence, this study aimed to assess the possibility of using natural surfactants and saponin-rich extracts to produce emulsions containing antibacterial and antioxidant cinnamon and clove essential oils (EOs). The analyses of nanoparticles using dynamic light scattering showed that the addition of plant extracts to solutions allows one to obtain stable emulsions and decreased zeta potential (< −40 mV) and droplet size (<200 nm). In all investigated emulsions, the increase of antioxidative properties was observed when both EOs and plant extracts were used. The emulsion with clove oil stabilized with Quillaja saponaria bark saponins has the highest combined antioxidative properties (3.55 ± 0.01 μg gallic acid equivalent per g). Additionally, a stronger antibacterial action against Pseudomonas bacteria was observed for clove oil with Quillaja saponaria and cinnamon oil with Glycyrrhiza glabra. In addition, plant extracts did not affect significantly the other properties of the oil emulsions, e.g. wettability, colour, and refractive index. All results show that the proposed emulsions can be helpful in the preparation of multifunctional emulsions, where the co-action of saponins and EOs is especially beneficial.

visualidad y el ferrocarril en la literatura de viajes: “En el lago Pátzcuaro”, recuperación de un cuento de Rubén M. Campos
Authors: Hernández Suárez Diana Marisol
Published: July 2023

A partir de un estudio de la “arqueología de los medios” en la producción de imaginarios artísticos, el interés por recuperar de las páginas de la Revista Moderna de México el cuento “En el lago Pátzcuaro” de Rubén M. Campos es mostrar la forma cómo impactó el ferrocarril en la producción de relatos artísticos en el afán de relatar la experiencia poética del viaje a través del territorio nacional. El ferrocarril, como un artefacto productor de miradas, traería consigo un proceso de transformación estética para la producción de reproducciones visuales en la prensa literaria del entresiglos mexicano. Específicamente interesa mostrar este relato como un ejemplo de cómo las tecnologías de la mirada –fotografía e ilustraciones– posibilitan la aparición de propuestas híbridas de representación de la experiencia del viaje, aspecto que aparece ligado al desarrollo del ferrocarril como medio de comunicación y transporte.
Escenografías autoriales en "Nocturno de San Ildefonso" de Octavio Paz
Authors: De Teresa Ochoa Adriana
Published: July 2023

El objetivo de este artículo es analizar en “Nocturno de San Ildefonso” (1974) las diversas “escenografías autoriales”, como denomina José-Luis Diaz al dispositivo en el que se inscribe el “escritor imaginario” para asumir una postura o identidad literaria y estructurar su desempeño público. En este poema de evocación autobiográfica el poeta ya sexagenario rememora y reconstruye fragmentariamente su pasado juvenil, sus primeras inquietudes estéticas e ideológicas, así como su iniciación poética. De clara raigambre romántica, las escenografías autoriales presentes en Nocturno de San Ildefonso constituyen el marco para su autofiguración madura como poeta vidente y su autorrepresentación juvenil como ideólogo y polemista en ciernes, al tiempo que define, mediante poderosas imágenes, su concepción poética.
Computer simulation of the microprocessor liquid level automatic control system

Published: July 2023

Today, automation occupies a leading place in most branches of modern society, in almost all types of industry and economy. One of the main tasks of designing modern automatic control systems is the realization of high indicators in terms of accuracy, control range, and speed, taking into account the features of the control object itself. The purpose of the work –researching the microprocessor system of automatic control of the liquid level by means of computer modeling, taking into account the transport delay, the nonlinearity of the control characteristic of the pump and the presence of an insensitivity zone. To achieve the goal, the following tasks were solved: a computer model of a closed microprocessor system for automatic control of the liquid level wasdeveloped, taking into account the nonlinearity of the characteristics of the pumping unit and transport delay; a number of experiments were conducted to find the values of PI-regulator coefficients that bring the transient process of a real system with a transport delay as close as possible to the transient process of a system in which there is no transport delay; search for optimal values of the coefficients of the PI controller by minimizing the functional of the root mean square deviation of the real from the specified transient processes. As a result of research, it was established that the minimum points of the functional for the control signal and the liquid level do not coincide. At the same time, at the minimum point of the functional for the liquid level, a larger amplitude of oscillations of the control signal is observed, and at the minimum point of the functional for the control signal –an increase in the duration of the transient process. Therefore, the final decision should be based on the selection of priorities or optimal ratios between the speed and wear of the equipment, which is due tothe instability of the control signal.
A survey on deep learning based face detection
Authors: Tran Tran The Vinh , Nguyen Tien Thi Khanh , Thanh Tran Kim
Published: July 2023

The article has focused on surveying face detection models based on deep learning, specifically examining different one-stage models in order to determine how to choose the appropriate face detection model as well as propose a direction to enhance ourfacedetection model to match the actual requirements of computer vision application systems related to the face. The face detection models that were conducted survey include single shot detector, multi-task cascaded convolutionneural networks, RetinaNet, YuNet on the Wider Face dataset. Tasks during the survey are structural investigation of chosen models, conducting experimental surveys to evaluate the accuracy and performance of these models. To evaluate and provide criteria for choosing facedetection suitable for the requirements, two indicators are used, average precision to evaluate accuracy and frames-per-second toevaluate performance. Experientialresults were analyzed and used for making conclusions and suggestions for future work. For our real-time applications on face-related camera systems, such as driver monitoring system, supermarket security system (shoplifting warning, disorderly warning), attendance system, often require fast processing, but still ensures accuracy. The models currently appliedin our system such as Yolos, Single ShotDetector, MobileNetv1 guarantee real-time processing, but most of these models have difficulty in detecting small faces in the frame and cases containing contexts, which are easily mistaken for a human face. Meanwhile, the RetinaNet_ResNet50 model brings the highest accuracy, especially to ensure the detection of small faces in the frame, but theprocessing time is larger. Therefore, through this survey, we propose an enhancement direction of the face detection model based on the RetinaNet structure with the goal of ensuring accuracy and reducing processing time.

In order to increase image formation productivity, the improvement of existing light reflectance models and the development of new models are constantly carried out. In the article the development of a combined light reflectance model based on the cosine-power functions is described. The main aspects of surface bidirectional reflectance distribution functions calculation and usage are analyzed. The features of simple empirical models and theoretical models that take into account microfacetedsurface representation are described. The disadvantages of existing surface reflectance models are discussed. The cosine-power functions of the fourth and sixteenth degreesare discussed. The necessity of the development ofanew surface reflectance model based on two cosine-power functions is justified. The calculation formula of the developed combined surface reflection functionis proposed. The formula oftheconnection point of two cosine-power functions was obtained.

Published: July 2023

Atherosclerosis and its complications, fatty liver diseases, insulin resistance (IR), type 2 diabetes, osteoarthritis, rheumatoid arthritis, and cancer are just a few of the age-related oxido-inflammatory responses that are predisposed by metabolic pathologies brought on by excess adiposity. Intriguingly, adipose tissue is an organ capable of mediating biological effects on inflammation and metabolism, which aids the maintenance of energy homeostasis. These reviews highlight the importance of understanding the metabolic and oxido-inflammatory pathways and homeostasis, and the molecules that are essential to the metabolic and pathogenic signaling sensor pathway systems. This may be helpful to understand the mechanisms and potential treatment options that will boost the endogenous molecules for prevention of stress and inflammatory conditions induced through metabolic signaling. In conclusion, this review study shows that problems caused by poor metabolic homeostasis may be successfully resolved. Hence, in the future, different adipocytokines route that mediated control of oxido-inflammation via modulation of ICDH, PPAR- γ, NR4A1, ChREBP and SREBP-1c will be highly effective for preventing metabolic disease. In this review, we attempt to summarize our current understanding of the Physiological role of adipogenic transcription factors in metabolic pathologies-related oxido-inflammatory responses, focusing on recent studies that explore the ICDH, PPAR- γ, NR4A1, SREBPs and ChREBP signaling pathways for the preventions of metabolic pathologies-related oxido-inflammatory responses.
Groundwater evaluation in Magdalena middle valley, Colombia: δ13C evolution in dissolved inorganic carbon
Authors: Fortaleché Rodríguez Yaritza Fernanda , Peña Urueña Mary Luz , Cadena Sánchez Ariel Oswaldo
Published: July 2023

In the present study, the evaluation of groundwater is carried out with isotopic studies of δ13C. Isotopic fractionation studies (δ13C) allowed for the identification of trends in dissolved inorganic carbon (DIC) behavior in groundwater from the northern area of the Valle Medio del Magdalena basin, confirming that different sources contributing to DIC can be distinguished. By complementing the analysis with 14C values, the evolution of DIC in open systems versus closed systems was discriminated. However, due to the heterogeneity of the area, it is important to conduct local characterizations, considering the water mixtures that occur due to the complexity of both the surface and underground aquifer systems. While highlighting the main sources of DIC, it is important to note that they are not the only one present. The results indicate that to the north of the study area the DIC evolution is influenced mainly by inorganic interaction, while to the south fractionation is more related to organic interactions are observed.

The article reveals the concept of societal in the political-economic discourse, and shows its connection with the relevant philosophical and sociological vision. It is argued that the current Russian-Ukrainian war has clear signs of a modern hybrid war, which is generated by the global-local hybrid system of "peace – war" and combines a whole range of means, from military-political and economic to cybernetic and cultural and humanitarian ones. Based on the combination of political-economic and sociological discourses in a broad sense, it is substantiated that the main components of the hybrid system "peace – war" from the point of view of the transformation of social relations are: armed-military, financial-economic, and informational-spiritual components, which cause a comprehensive impact on people’s worldview, positioning and behavior, which leads to significant societal consequences. The authors give various characteristics of the institutional dimension of the war’s societal consequences. Theoretically, the phenomenon of emergent institutional order is taken as the basis for considering the institutional dimension of the societal consequences caused by the hybrid war. It is revealed that in the martial law conditions, the role of the trust institution is growing (the trust institution is considered as a defining and integral construct of the socio-economic system’s institutional architecture, embodied both in trust in the state and power structures, and in trust in new institutions created by the hybrid war (volunteers and various forms of amateur civil movements)). The authors show that in the context of societal development in the conditions of war shocks and post-war recovery of Ukraine, the quality of institutions and the state’s institutional potential play an extremely important role. Analysis of the societal consequences of the Russian Federation’s invasion in Ukraine in the institutional dimension shows the need to overcome the key institutional destructions generated both in the previous period and during the war. Also, it is necessary to create an institutional basis for a new economic model focused on ensuring a combination of Ukrainian effective reconstructive recovery in the post-war period and its full integration into the European Union and the world space.

Emil Artin (1898-1962): Seine wissenschaftlichen Ergebnisse in der Mathematik erregten allgemeine Aufmerksamkeit und hatten weitreichende Konsequenzen für die Forschung. Der glänzende Stil seiner Vorträge wies ihn als virtuosen Denker aus und machte ihn zum begehrten Lehrer. Artin war Ordentlicher Professor am Mathematischen Seminar an der Universität Hamburg. Als die Nationalsozialisten ihn 1937 aufgrund der "Nürnberger Gesetze" in den Ruhestand versetzten, emigrierte er in die USA. Erst 1958 kehrte er wieder an die Universität Hamburg zurück.
The Subject’s Guide to the Realms of Karma
Authors: Vrhovski Jan
Published: July 2023

This article analyses the work of the Dharma Master Taixu, one of the leading figures of Chinese Buddhism in the Republican Period. Its analysis focuses on the meaning of concepts such as “human life,” “freedom,” and “karma” in Taixu’s seminal writings on the role of Buddhism in modern society, politics, and science from the 1920s and early 1930s. The succession of reading notes and reflections on these quintessential concepts in Taixu’s works aims at shedding some light on the relationship between subject and object, and the key question of the autonomy of the subject in modern Chinese Buddhism. Finally, by trying to illuminate the content of the ideas of subject and freedom in the work of this key figure, whose work is a foundational building block in the modernization of Buddhism in East Asia, the present discussion aims at casting some new light on the origins and theoretical foundations of contemporary Buddhism in Taiwan as well as in the broader Chinese cultural sphere.
The gender of language contact
Authors: Narayanan Sandhya Krittika
Published: July 2023

This article considers how language contact is gendered through an analysis of how inter-Indigenous Quechua–Aymara boundary maintenance practices and ideologies are feminised in the Peruvian altiplano. The analysis focuses on the semiotic regimentation of Indigenous ethnolinguistic boundaries, concentrating on the role of four Indigenous female figures: the Indigenous wife; the Indigenous female market vendor; the reimagined mythic Indigenous founding mother; and the Indigenous beauty pageant contestant. An ethnographically grounded, scalar analysis of Quechua–Aymara contact in the region shows how each of the female figures is ideologically linked to a specific aspect of inter-Indigenous language contact and boundary maintenance. Furthermore, the discussion shows the interconnectedness of these female figures and their associated ideologised practices and discourses, which lead to the feminisation of inter-Indigenous language contact in the region.

A partir de estudo bibliográfico, documental e empírico, essa pesquisa qualitativa pretende: i) cartografar o oferecimento da educação para alunos de uma região periférica bastante populosa da Grande São Paulo – SP; ii) problematizar o direito à educação a partir do cumprimento de políticas públicas e legislações sobre o ensino público; iii) discutir o direito à educação e à saúde como prerrogativas para a formação para a cidadania ativa. Método: visitas realizadas à escola situada na periferia da Grande São Paulo; diários de campo de conversas e entrevistas realizadas com ex-gestores e professores, totalizando 20 pessoas. Resultados: o material coletado foi organizado em torno de quatro eixos centrais: aspectos de segurança ambiental do; o direito à educação de crianças da periferia; os direitos à saúde como decorrência da cidadania a ser construída na escola e, por fim, a visão da gestão sobre o cumprimento da garantia de direitos da população periférica.
PRESENTATION OF CONCEPTS IN A CHILDREN’S SCIENCE COMMUNICATION BOOK: THE CASE OF “ISAAC NO MUNDO DAS PARTÍCULAS”
Authors: Araujo João Felipe Viana de , Lima Guilherme da Silva , Almeida Sheila Alves de
Published: July 2023

ABSTRACT: This work aims to analyze the scientific ideas and concepts present in the science communication book aimed at the child’s public “Isaac in the World of Particles”, written by Elika Takimoto. We start from the contributions of historical-cultural psychology on the potential, spontaneous and scientific concepts, seeking to understand the relations and forms of meaning of the scientific ideas presented by the work. Excerpts from the book in which scientific concepts or key ideas were present were selected and analyzed. The unit of analysis was the word. The results indicated that the book mobilizes several meanings and logical-abstract (conceptual) structures to formalize complex elaborations and scientific concepts. The analysis of the concepts: atom, particle and vacuum, indicated strategies for the meaning production, which contemplated: argumentative disputes, contextualization, curiosity, history of science, spontaneous concepts etc.
CHARACTERIZATION OF A CAPILLARY-DRIVEN FLOW IN MICROGRAVITY BY MEANS OF OPTICAL TECHNIQUE

Published: July 2023

The motion of a gas-liquid interface along a solid wall is influenced by the capillary forces resulting from the interface's shape and its interaction with the solid, where it forms a dynamic contact angle. Capillary models play a significant role in the management of cryogenic propellants in space, where surface tension dominates the behavior of gas-liquid interfaces. Yet most empirical models have been derived in configurations dominated by viscous forces. In this study, we experimentally investigate the wetting of a low-viscosity, highly wetting fluid in a reduced gravity environment. Our setup consisted of a transparent and diverging U-tube in which capillary forces sustain the liquid motion. Combining particle image velocimetry (PIV) and high-speed backlighting visualization, the experimental campaign allowed for measuring the interface evolution and the velocity field within the
liquid under varying gravity levels. This work reports on the preliminary results from the image velocimetry and shows that the velocity profile within the tube is close to parabolic until a short distance from the interface. Nevertheless, classic 1-D models for capillary rise face difficulties reproducing the interface dynamics, suggesting that the treatment of the surface tension in these problems must be reviewed.

Published: July 2023

Background: Lycianthes moziniana (Capsiceae, Solanaceae) is an endemic and widespread species in Mexico. Morphological and molecular evidence suggested three varieties (L. moziniana var. margaretiana, L. moziniana var. moziniana and L. moziniana var. oaxacana).

Hypotheses: Lycianthes moziniana is integrated by differentiated lineages corresponding to the three varieties identified.

Studied species: Lycianthes moziniana (Dunal) Bitter.

Study sites and dates: Mexico from 2017 to 2021.

Methods: We measured 11 morphological characters based on 207 herbarium specimens. Discriminant Canonical Analysis (DCA), Mahalanobis Square Distance (MD) and Canonical Classificatory Analysis (CCA) were used to uncover the differences among varieties. For geographic and climatic preferences and divergence, we used 288 records and four climatic layers.

Results: Two canonical functions explained 100 % of the morphological variation and seven characters had the highest discriminatory power. In addition, MD was statistically significant. Meanwhile, the CCA recovered three groups at 77 %. The morphological evidence demonstrated the distinctiveness of L. moziniana var. moziniana. In contrast, L. moziniana var. margaretiana and L. moziniana var. oaxacana were morphologically similar. The identity test showed significant differences among Ecological Niche Models (ENMs). The evidence indicates geographic and climatic isolation among the varieties. Lycianthes moziniana var. moziniana is widespread and has intermediate overlap with the other two varieties. Lycianthes moziniana var. margaretiana and L. moziniana var. oaxacana were isolated in different biogeographical provinces and showed the lowest overlap.

Conclusions: Morphological and geographic data indicates incipient speciation is occurring.
CONVERGENCE OF TRADITIONAL CORPORATE GOVERNANCE AND MODERN CORPORATE GOVERNANCE REFORMS: IS KING II déja vu FOR BOARDS OF DIRECTORS OR IS IT A SET OF NEW PRINCIPLES?
Authors: Tshepo Mongalo
Published: July 2023

Contrary to popular belief, corporate governance is not a new subject. In fact, corporate governance has been practised for as long as there have been corporate entities. Corporate governance has always been reflected in legislation such as the Companies Act, Insolvency Act, Insider Trading Act and similar legislation. However, some of the recent recommendations resulting from reforms in this area reflect the improvement of corporate governance standards. This article is an attempt to point out similarities and divergences between traditional corporate governance and modern corporate governance as suggested by the latest reforms, particularly in the King Report on corporate governance (2002).
