Different contents of manganese oxide (MnO2) and zinc oxide (ZnO) were combined with polyvinyl alcohol (PVA) to form flexi MnO2/PVA as well as ZnO/PVA nanocomposite films. XRD as well SEM methodologies are used to evaluate the properties of the fabricated films. The XRD analysis demonstrates that MnO2/PVA as well as ZnO/PVA composites were effectively fabricated. The SEM pictures show that MnO2 and ZnO are uniformly dispersed throughout the PVA polymeric chains. Furthermore, the electrical conductivities, dielectric permittivity, electric moduli behaviors, as well as dielectric impedances of PVA, MnO2/PVA, ZnO/PVA films were recorded using LCR method in frequencies 102 to 106 Hz. At 105 Hz, the dielectric enhanced from 2.05 for PVA to 5.5 on PVA/5%ZnO and 4.15 for PVA/10%MnO2, while the conductivities increase from 1.05x10-7 S/cm for PVA to 4.01x10-7 S/cm for PVA/5%ZnO and to 5.4x10-7 S/cm for PVA/10%MnO2. The current work pave the way to using of ZnO/PVA and MnO2/PVA flexi nanocomposite films in a different uses including battery, super-capacitors, as well as storage devices.

Vesicular transport is a means of communication. While cells can communicate with each other via secretion of extracellular vesicles, less is known regarding organelle‐to organelle communication, particularly in the case of mitochondria. Mitochondria are responsible for the production of energy and for essential metabolic pathways in the cell, as well as fundamental processes such as apoptosis and aging. Here, we show that functional mitochondria isolated from Saccharomyces cerevisiae release vesicles, independent of the fission machinery. We isolate these mitochondrial‐derived vesicles (MDVs) and find that they are relatively uniform in size, of about 100 nm, and carry selective protein cargo enriched for ATP synthase subunits. Remarkably, we further find that these MDVs harbor a functional ATP synthase complex. We demonstrate that these vesicles have a membrane potential, produce ATP, and seem to fuse with naive mitochondria. Our findings reveal a possible delivery mechanism of ATP‐producing vesicles, which can potentially regenerate ATP‐deficient mitochondria and may participate in organelle‐to‐organelle communication.
The androgen-thyroid hormone crosstalk in prostate cancer and the clinical implications
Authors: Torabinejad Sepehr , Miro Caterina , Barone Biagio , Imbimbo Ciro , Crocetto Felice , Dentice Monica
Published: March 2023

There is increasing evidence that thyroid hormones (THs) work in an integrative fashion with androgen receptors (ARs) to regulate gonadal differentiation and reproductive function. Studies reveal that THs have interactions with the AR promoter region and increase AR expression. THs also have a role in the regulation of enzymes involved in the biosynthesis of androgens, such as 5α-reductase, which is essential in the conversion of testosterone into its active form, 5α-dihydrotestosterone. Additionally, the presence of androgen response elements in the promoter regions of TH-related genes, such as deiodinases and TH receptor isoforms, has been identified in some vertebrates, indicating a mutual interaction between THs and ARs. Since the androgen signaling pathway, mediated by ARs, plays a key role in the formation and progression of prostate cancer (PCa), the existence of crosstalk between THs and ARs supports the epidemiologic and experimental evidence indicating a relationship between the high incidence of PCa and hyperthyroidism. This article aims to review the role of androgen-TH crosstalk in PCa and its implication in clinical management. As life expectancy is growing these days, it can increase the number of patients with PCa and the critical relevance of the disease. In order to gain better knowledge about PCa and to improve clinical management, it is essential to get better insight into the key factors related to the formation and progression of this cancer.

Published: March 2023

Micronutrients consumed in excess or imbalanced amounts during pregnancy may increase the risk of metabolic diseases in offspring, but the mechanisms underlying these effects are unknown. Serotonin (5-hydroxytryptamine, 5-HT), a multifunctional indoleamine in the brain and the gut, may have key roles in regulating metabolism. We investigated the effects of gestational micronutrient intakes on the central and peripheral serotonergic systems as modulators of the offspring's metabolic phenotypes. Pregnant Wistar rats were fed an AIN-93G diet with 1-fold recommended vitamins (RV), high 10-fold multivitamins (HV), high 10-fold folic acid with recommended choline (HFolRC), or high 10-fold folic acid with no choline (HFolNC). Male and female offspring were weaned to a high-fat RV diet for 12 weeks. We assessed the central function using the 5-HT2C receptor agonist, 1-(3-chlorophenyl)piperazine (mCPP), and found that male offspring from the HV- or HFolRC-fed dams were less responsive (P < 0.05) whereas female HFolRC offspring were more responsive to mCPP (P < 0.01) at 6 weeks post-weaning. Male and female offspring from the HV and HFolNC groups, and male HFolRC offspring had greater food intake (males P < 0.001; females P < 0.001) and weight gain (males P < 0.0001; females P < 0.0001), elevated colon 5-HT (males P < 0.01; females P < 0.001) and fasting glucose concentrations (males P < 0.01; females P < 0.01), as well as body composition toward obesity (males P < 0.01; females P < 0.01) at 12 weeks post-weaning. Colon 5-HT was correlated with fasting glucose concentrations (males R2=0.78, P < 0.0001; females R2=0.71, P < 0.0001). Overall, the serotonergic systems are sensitive to the composition of gestational micronutrients, with alterations consistent with metabolic disturbances in offspring.

Published: March 2023

This article presents the results of an action that characterizes in depth the sociocultural meanings that the cyclists of the Department of Nariño build, from their sports practice, following the line of thought proposed by Skinner and Ballestero, the categories of analysis are: the object and the moment. The methodology used in this study was based on the qualitative paradigm, the historical-hermeneutic approach and the method used was phenomenology. The data collection technique used was the semi-structured interview; the script of questions was built, which was validated through expert judgment. The work unit for this article was made up of 10 road cyclists from the Department of Nariño. The results show that, although the cyclists interviewed have different levels of training, there are recurrences in the sociocultural meanings that they attribute to the object and the moment. It is concluded that road cycling is an object - construct, since its meaning has been constructed through the assimilation of practitioners' perceptions and in the case of the moments category, it was possible to identify that life stories have similarities with the history of cycling in Nariño in general.
Use of bacterial cellulose in degraded paper restoration: Effect on visual appearance of printed paper
Authors: Gómez Nuria , Santos Sara M. , Carbajo José M. , Villar Juan C.
Published: March 2023

One of the most common methods used to reinforce damaged paper is to apply a lining, using Japanese paper (JP). The reinforcing material must consolidate the paper without modifying its visual appearance. The unique properties of bacterial cellulose (BC) suggest that it could be efficiently used to reinforce degraded paper documents. The changes in the visual appearances of the printed commercial papers lined with BC and JP were examined in this study. Four commercial papers, coated and uncoated, were printed with cyan, magenta, yellow, and black offset inks. The printed samples were lined with BC and JP sheets. Print density, gloss, and CIELab coordinates were tested in the lined and unlined samples before and after aging. Lining with JP notably affected the print density and CIELab coordinates. The lining with BC resulted in lower decrements in color intensity. The gloss values of samples lined with BC differed widely amongst the papers, whereas in papers reinforced with JP these values never exceeded 6%. Subjecting the samples to an aging process did not markedly modify the results except for the BC-lined samples, in which color differences increased.
Assessment of the thermal characteristics of pellets made of agricultural crop residues mixed with wood
Authors: Kamperidou Vasiliki , Lykidis Charalampos , Barmpoutis Panagiotis
Published: March 2023

The use of agricultural biomass to produce biofuels and energy can provide many environmental and socio-economic benefits. This research project examines the possibility of replacing part of the wood material in a pellet with various proportions of residues of agricultural crops such as medic, maize, wheat bran, wheat straw, sunflower, and cardoon. Such substitution would contribute to the recycling of materials and the sustainable use of wood and other natural resources. It would reduce emissions of gaseous pollutants by replacing the use of other fossil fuels with solid biofuels. The chosen agricultural species, as well as the beech wood used in this work, are among the most widely-available raw materials in Greece and Europe. Specifically, the higher heating value (HHV) of these materials, both separately and mixed, and their respective ash contents (%), a feature highly crucial for their future utilization as biofuels, were estimated and compared among species. Additionally, various mixing ratios of these materials were examined to determine the most appropriate pellet-type biofuels that meet the requirements of the corresponding international standards that pose restrictions on thermal efficiency and ash content.
Cationization of lignocellulose as a means to enhance paper strength properties
Authors: Mayr Melanie , Odabas Nora , Eckhart Rene , Henniges Ute , Bauer Wolfgang
Published: March 2023

Chemical modification by attaching functional groups to lignocellulosic pulp fibers might be a strategy for improving the pulp, and thereby, paper properties. Several studies have described positive effects on paper strength properties for handsheets prepared from cationic-modified pulp or pulp fractions. This study addressed whether these effects are related to the cationic groups, e.g., by increasing electrostatic attraction and thus paper strength, or rather side effects of the chemical modification process, e.g., fiber flexibilization. To eliminate or at least minimize these side effects, only the fines fraction, which was already highly flexible, was cationized. While the addition of cationized fines affected various pulp and paper properties, most notably drainage time, no difference in strength properties was observed when comparing the addition of cationic or unmodified fines to different pulps or fractions thereof.
Feasibility and concurrent remediation of red mud as an in situ pyrolysis catalyst

Published: March 2023

Catalytic pyrolysis may serve as an alternative production strategy to petroleum-derived fuels and chemicals. Furthermore, red mud, a toxic industrial bauxite byproduct, could serve as a sustainable catalyst and overcome the need for more robust catalysts. To test this, in situ catalytic pyrolysis was run on a semi-pilot scale reactor with various ratios of red mud and switchgrass (Panicum virgatum). Authors hypothesized that the coking process would render red mud environmentally friendly, improve soil quality, and yield for bioenergy crop production, like biochar. Therefore, this work investigated red mud’s capability to enhance bio-oil quality, as well as, how the modified biochar produced from in situ pyrolysis affected switchgrass seedling vigor, and root/shoot mass. The results indicated that red mud was effective at increasing soil pH and biochar and bio-oil yields, while reducing the total acid number in bio-oil. While a high loading of reacted red mud had a negative impact on plant yield, the addition of uncatalyzed biochar to pure red mud considerably improved the seedling yield in marginal soils. These results suggest that this technology has potential for valorizing a waste stream and creating a soil amendment from red mud that closes nutrient and bioenergy production cycles while potentially reducing soil pollution.

Published: March 2023

This work aimed to study the technical feasibility of using industrial gypsum, expanded polystyrene (EPS), and cellulose solid wastes in the production of acoustic insulation panels for buildings. Five traces of acrylic gypsum matrix were produced with variations in the proportions of cellulosic pulp and EPS and always maintaining the same proportion of recycled gypsum and water. The composites produced were tested according to the ISO 10534-2 (2015) standard for the determination of the coefficient of sound absorption and ABNT NBR 14715-2 (2010) for bending tests. The results didn’t show statistically significant differences in the coefficient of sound absorption with variations in the quantities of each material. However, the sonic frequency of the tests directly influenced the results, presenting a better performance at a low frequency (250 Hz). The results qualify the composite produced for use as acoustic insulation and can be used in plates for sound reflection in buildings in places where it doesn’t require resistance to great stresses.
Use of lignin side-streams from biorefineries as fuel or co-product? Life cycle analysis of bio-ethanol and pulp production processes
Authors: Secchi Michela , Castellani Valentina , Orlandi Marco , Collina Elena
Published: March 2023

Increasing the profitability of lignin side-streams is a challenge in the scientific community. Lignin residue originates from black liquor and lignin cake, which are residues from pulp and bio-ethanol production. This paper presents a life cycle assessment study to investigate how pulp and bio-ethanol processes vary in their environmental performance when a fraction of lignin is removed and to identify the best alternative energy source. Fossil energy, natural gas, and cogeneration were evaluated as heat and power alternative sources. The results showed that lignin removal does not considerably affect the environmental performance of the baseline systems and does not generate a relevant risk of “burdens shifting.” Natural gas was the best alternative of power source in a bio-ethanol system, whereas cogeneration showed better compatibility with pulp mills. For the analyzed systems, the necessary allocation distributed the impact contributions between the main products (bio-ethanol/pulp) and the co-products (lignin-cake/black liquor), counterbalancing the impact increase due to the introduction of the new heat, electricity supply, and additional treatment aimed at lignin extraction. Finally, sensitivity analyses confirmed the low influence on the results of the substitution ratio.
Bio-based polymers for sustainable packaging and biobarriers: A critical review
Authors: Helanto Karoliina , Matikainen Lauri , Talja Riku , Rojas Orlando J.
Published: March 2023

Barrier materials have an important role in various packaging applications, especially considering the requirements associated with protection and shelf life. Most barrier materials used in today’s industry are either manufactured from oil resources or metals. Driven by the increase in environmental awareness, access to oil resources as well as legislation, new and environmentally benign alternatives are at the center stage of scientific and industrial interest. This article covers the use of wood-derived polymers and those produced from microorganisms, which display remarkable barrier properties. Wood-based products have received great attention for their air/oxygen resistance. As far as their properties, microorganism-derived biopolymers are comparable to conventional oil-based thermoplastics, but their cost may still be an issue. Both, wood and microorganism-derived biopolymers are challenged when moisture, grease and oxygen resistance are simultaneously required. Hence, multilayer structures and composites are needed to fulfill the most demanding requirements of packaging materials. Here we offer a review of these topics together with a discussion of their prospects.

Published: March 2023

The drilling and research communities are leading the way toward more digitally-controlled operations to ensure that the drilling process takes place as safely and gently as possible with the lowest possible carbon footprint. Today’s cutting-edge operations are run on large high-performance drilling installations where operations are largely run remotely from the driller’s operating station. Digitalization of the drilling process is the goal for performing drilling operations remotely from onshore. Leak-off test (LOT) or extended leak-off test (XLOT) plays a critical role in the petroleum industry. Therefore, recognizing all affecting parameters on LOT/XLOT and Formation integrity test (FIT) performance is vital. Because, in some cases, it is not possible to fully understand what happened during the test, having a deep insight into the LOT procedure is very important. One of the current study's main objectives is to thoroughly explain all stages of these tests and assemble all the significant parameters. Thus, many scientific papers on these tests were deeply reviewed and were classified into four main groups focusing on the application of LOT/XLOT (i) in stress estimation and geomechanical studies, (ii) concerning hydraulic fracturing, (iii) concerning wellbore stability, and (iv) numerical modeling, and then, the corresponding discussions were conducted. It was found that in-situ stress estimation is the most common application of the leak-off test.
Moreover, considering the importance of LOT and the desire to digitize operations in the oil and gas industry, it was found that the automatic LOT/XLOT is a fully required approach. The primary purpose of this study, which is hence considered its main contribution, is to prepare a LOT flowchart that would set off the further code development tasks of the field. The fundamental code of the present study was written and checked using a real dataset in a Python environment. The results were satisfying and indicated a successful start, which lays a foundation for future automated LOT/XLOT tests.

On the Sociolinguistic Origins of the term Qazaq: A Proposal for an Alternative Etymology of ‘Cossack’/‘Kazakh’ and an Argument for the Analytical Usefulness of Register in Historical Linguistics
Authors: Lewis Patrick C.
Published: March 2023

Although the word qazaq is widely agreed to be the common ancestor of both ‘Cossack’ and ‘Kazakh’, there remains uncertainty about qazaq’s etymology. This paper proposes that qazaq originated as a variant of the central Turkic etymon qaç(g)aq and thus derives from the Common Turkic root qaç- (‘flee’). The paper draws on data generated through the traditional methods of historical linguistics—the comparative method and philological analysis—in conversation with recent work in anthropological and sociolinguistics on the concept of linguistic ‘register’ to better theorize qazaq’s historical development and the variation in its forms and meanings.

Sutra-copy Fragments in Calligraphy Albums
Authors: Kamens Edward
Published: March 2023

In the early-modern Japanese genre of calligraphy albums called tekagami, fragments of copies of sutras are an outstanding presence, but that presence raises questions about their provenance, condition, status, and significance within such settings. This article delves into these and other questions, with a focus on a set of examples in Tekagamijo, an album in the collection of the Beinecke Rare Book and Manuscripts Library, Yale University. The author suggests that sutra-copy fragments (J. shakyogire) have undergone a transformation or ontological shift that replaces their original sacred character with a new, contextually constructed significance that can best be understood through comprehension of the attitudes of the album’s compilers toward their materials and their task.
Using the characteristic search algorithm in a library fingerprint identification system
Authors: Peng Tuofu
Published: March 2023

As an important identification method, fingerprint recognition has a wide range of applications. To make the fingerprint recognition system of a library more efficient and secure, a recognition technology based on the characteristic search algorithm is proposed, and the performance of the algorithm is analysed. When a reasonable threshold is set, the matching error rate of the algorithm can be controlled at a lower level, and the algorithm can also ensure a higher fingerprint recognition accuracy and determine the overall accuracy. At the same time, three other identification algorithms of the same type are introduced: radio-frequency fingerprinting, convolutional neural network and local binary pattern. In a comparative experiment, it was found that the characteristic search algorithm model had the highest accuracy, with a value of 94.8%. When dealing with the same amount of fingerprint data, the recognition time of the algorithm model was the shortest. In addition, the area under the curve value corresponding to the receiver operating characteristic curve of the algorithm was the largest, and its value was 0.94. It is well known that the performance of the characteristic search algorithm is optimal and can effectively improve the operation efficiency of a library fingerprint identification system.
From the physical to the digital: Encounters in the KKNK online gallery
Authors: Orton Dineke
Published: March 2023

This study explores the processes and curatorial techniques that support corporeal engagements with online exhibitions. Exhibitions, physical and otherwise, are a complex interplay between spaces - real and imagined -audiences, and tangible or intangible objects. This is a guiding notion of this article, supported by Merleau-Ponty's perspective of the relation between internal human experiences and the external bodily encounters that shape them. I maintain that differing digital curatorial presentations can enhance or subdue the embodied interaction of visitors. By relying on my lived experience of navigating the transfer of the Klein Karoo National Arts Festival's visual arts programme of 2020 to the online sphere, I discuss various strategies deployed to encourage embodied engagement. Amongst other findings, the study underscores the need to consider audience preferences and allowing visitors a sense of agency to choose how they want to engage artwork online. Even though the arena of exchange might differ, I argue that all exhibitions, whether online or brick-and-mortar, provide audiences with the possibility of an engaging experience. In addition to the exhibition itself, viewers embody another energy - and it is the viewer's deliberate performance and choice to interact that produces the distinctive experience of an exhibition.
Amphibians and Reptiles of Dinghushan in Guangdong Province, China’s Oldest Nature Reserve
Authors: Li Zhen-Chang , Xiao Zhi , Qing Ning , Lu Wen-Hua , Lazell James
Published: March 2023

Dinghushan is the only nature reserve at the Tropic of Cancer in mainland China with extensive old growth monsoonal hardwood forest. We here assemble a comprehensive list, with life history notes, of amphibians and reptiles of Dinghushan. Relevant records were scattered over three centuries since the first in 1886. A total of 71 species are known to occur in the reserve, and this number of species per area far exceeds that predicted by classic island biogeographic theory. Among these 71 species, nine are new records: Five frogs (Amolops ricketti, Hylarana macrodactyla, Hylarana taipehensis, Odorrana schmackeri, and Occidozyga lima) and four snakes (Oligodon cinereus, Sinonatrix percarinata, Sinomicrurus macclellandi, and Trimeresurus stejnegeri). One undetermined skink may confound the generic definitions for the genera of Scincella and Sphenomorphus. Among these 71 species, 21 that are not closely associated with old growth forest have not been seen recently. Forest recovery and reforestation of farmland over five decades since the nature reserve was established in 1956 may have contributed to the decline of these species. Dinghushan has 97% of its species occurring strictly in the Oriental zone; among them, about 78% (55) occur both in the South China and Central China regions, 21% (15) occur only in the South China region, and one species was previously known only from the Central China region. The unique location of Dinghushan makes long-term monitoring of its herpetofaunal diversity important for future collaborative studies on a global scale.

Evaluating Spatiotemporal Trends in Infrasound Propagation Using Seismoacoustic Arrivals from Repeating Explosions
Authors: Wynn Nora , Dannemann Dugick Fransiska , Carmichael Joshua D. , Thiel Andrew D.
Published: March 2023

Recent studies have demonstrated the utility of seismic stations for recording acoustic signals from events of interest. Here, we present an analysis of seismoacoustic arrivals originating from weekly controlled munition disposals at the McAlester Army Ammunition Plant (McAAP) in Oklahoma over a period of nine months during 2019. These arrivals were recorded on 121 temporary and permanent seismic stations across Oklahoma and surrounding states. Arrivals were identified by a human analyst team. Because of its consistency and duration, the McAAP dataset provides an opportunity to study the spatial and temporal variability of infrasound propagation because it relates to seasonally variable atmospheric conditions. Recorded arrivals identify an acoustic shadow zone ranging in distance from 50 to 200 km of the source, along with seasonal directional shifts in the stratospheric duct. Acoustic raytracing is used to produce comparisons of predicted and observed arrival dynamics, concluding that current atmospheric specifications do not capture the full complexity of the atmosphere.

Although the Qilian–Haiyuan fault is known to be responsible for major earthquakes up to M 8, the potential of damaging earthquakes near its western end is not well understood. Since January 2022, three moderate earthquakes (M 5.8, M 6.0, and M 5.4) occurred around the Halahu region of Delingha, China, near the western end of the Qilian–Haiyuan fault. These earthquakes are unusual M 5+ events in this low-seismicity region, and both the U.S. Geological Survey and Global Centroid Moment Tensor solutions suggest that the focal mechanisms of the three mainshocks are distinct from the activity characteristics of the nearby mapped faults. Thus, determining the precise source parameters and identifying the causative fault of this earthquake sequence are important to analyze its seismogenic settings and seismic hazard in this region. In this article, we determined the point-source parameters of the three moderate events via regional waveform modeling and found that these earthquakes are strike-slip events with the nodal planes striking nearly north–south and east–west directions. We then resolved its seismogenic faults by analyzing the aftershock distribution and the rupture directivity. The results show that both the M 5.8 and M 6.0 events ruptured along the north–south nodal plane and expanded toward the south for ∼4 km and ∼3 km, respectively, and the ruptured fault of the M 5.4 is difficult to distinguish. Furthermore, we constrained the relative location using the Interferometric Synthetic Aperture Radar observation, and the result is consistent with that obtained from seismic waveform data. We proposed that this earthquake sequence ruptured along an unmapped dextral fault, which forms a conjugate fault system with the sinistral strike-slip Qilian–Haiyuan fault. Its deformation mechanism may be controlled by long-term, protracted, nearly north–south-trending, right-lateral simple shear in the Qilian Shan fold-thrust belt. The accumulated static Coulomb stress changes resulted in the northwest of this ruptured fault being closer to failure in the future.

The Australian Seismometers in Schools (AuSIS) network operates 50 broadband seismic stations across Australia that are hosted at schools. The instruments augment the Australian National Seismograph Network providing valuable data from urban and regional Australia. The network coverage is quite sparse, but these vital records of rare, moderate Australian earthquakes can improve our understanding of the deformation within the stable continental region of Australia, especially for events with no surface rupture. In this study, we present the feasibility of identifying the fault plane of moderate earthquakes on the Australian continent, using data from the AuSIS network. We examine the fault plane of the September 2021 Mw 5.9 Woods Point earthquake that occurred about 130 km northeast of the Melbourne metropolitan area. We estimate the hypocenter and the centroid moment tensor (CMT) to identify the fault plane from the auxiliary plane in the focal mechanism. We explore a range of 1D models and a 3D Earth model to simulate seismic arrivals and full waveform data. The hypocenter is resolved using P- and S-wave arrivals in a probabilistic framework and the CMT is derived from full waveform modeling through grid search over a set of trial points around the hypocenter. Our solution suggests the mainshock ruptured the depth of 15 ± 4 km, with a strike-slip mechanism striking 348° north on a nearly vertical plane. The high double-couple percentage of this event indicates a simple rupture that propagated from the south (hypocenter) toward the north (centroid) and remained subsurface. This indicates that the causative fault had a deeper structure than the previously known shallow, northwest–southeast-striking faults of the region. The P and T axes deduced from our fault model are notably aligned with the maximum horizontal crustal stress in the region.

The eastern Tennessee seismic zone (ETSZ) experiences the second highest rates of natural seismicity in the central and eastern United States (CEUS), following the New Madrid area, yet the cause of elevated earthquake rates is unknown. We probe the origin of ETSZ seismicity using geomechanically constrained stress inversions of earthquake focal mechanisms from 57 earthquakes, including 24 newly derived here and five from the recent events not used in the previous stress studies. Highly oblique northwest–southeast (NW–SE) extension that is unique in the CEUS dominates the ETSZ—central Alabama to southeastern Kentucky—and preferentially reactivates normal to strike-slip faults in the northeast (NE) and southwest (SW) quadrants (strikes 018°–086° or 196°–272° and dips 55°–90°). This extension cannot be explained by the compressive tectonic plate-boundary tractions that cause oblique NE–SW contraction elsewhere in the CEUS. Although our analyses do not uniquely determine the origin of the anomalous stress, we favor isostatic disequilibrium, due to anything from surface processes to crust–mantle interactions, as the possible cause. Increased long-term seismic hazard in the ETSZ may be controlled by and confined to the spatial extent of this anomalous seismotectonic state.
Saberes previos, mediación pedagógica y aprendizaje en la gestión de la educación universitaria

Published: March 2023

La educación universitaria corresponde al nivel terciario y está orientada a la formación de profesionales competentes con dominio de las habilidades duras de la especialidad y habilidades blandas para el éxito en su desempeño profesional. Durante el proceso de profesionalización, deben aprovecharse todas las experiencias que trae y que gravitaron para la elección de la carrera. Por ello, el aprendizaje en la buena práctica de la gestión universitaria requiere saberes previos y mediación del docente; sin embargo, existe una tendencia a promover enseñanzas con escasa guía pedagógica debido a orientaciones constructivistas sobre la autonomía del estudiante y existen pocos estudios que muestran los resultados de tales prácticas educativas. La presente investigación tiene como objetivo demostrar que los niveles de mediación pedagógica tienen efecto diferente en los resultados de aprendizaje según los niveles de saberes previos. El diseño de investigación es cuasi experimental, con una muestra de veintiséis estudiantes universitarios de grupo intacto, a partir del cual se formaron los grupos experimental y control con asignación aleatoria. A ambos grupos se les midió el nivel de saberes previos antes del experimento; luego, solo al grupo experimental se proporcionó alta mediación pedagógica y el grupo de control actuó como testigo. Los resultados muestran que los estudiantes con bajos saberes previos se perjudican con escasos niveles de mediación; mientras que, en los estudiantes con altos saberes previos, los niveles de mediación no tienen efecto significativo.

The article presents some results of an interdisciplinary study aimed at clarifying the conditions for the use of cardiometric and electrodermal indicators of human activity as a means of attesting to visual online content. To record personal reactions to selected visual objects, the authors use a range of tools, including computer cardiometers, portable eye trackers and polygraphs of various modifications. To achieve this goal, the authors conducted a multi-level test of Russian youth using current political symbols and images from online communities and other social media platforms. The results of the study prove the high efficiency of using cardio-oculometric detection combined with automatic recording of electrodermal activity to obtain reliable information about affective and rational-logical features of perception of visual online content. The study also extends the research understanding of the specifics of using this combination of diagnostic tools in different conditions.
Blockchain-Based Welfare Distribution Model for Digital Inclusivity
Authors: Tartan Chloe
Published: March 2023

An unprecedented rate of technological advancement, compounded by the COVID-19 pandemic, has expedited our transition to a fully digitalised society. Traditionally, digital inclusion focuses on an individual's ability to connect to and access information from the internet. The adoption of novel technologies such as artificial intelligence and blockchain is little distinguished in the literature from internet accessibility. While these digital solutions present novel opportunities, they may also perpetuate or exacerbate the existing hurdles faced by digitally excluded localities. However, these technologies could also be used to tackle the digital divide. Inspired by the design of Bitcoin, the current study offers a conceptual blockchain-based welfare model that adopts a two-pronged approach to enable the fair distribution of capital and resource allocation across the UK regions. The model offers transparency over institutional processes and improves their trustworthiness while preserving privacy. At the community level, the model assumes the application of economic incentives in order to promote digital inclusivity and stimulate cooperation and competition within local cultures. By mobilising both public institutions and communities, such a holistic model would assist the flow of information between the supply and demand side of the regional economy. This approach may not only help to dissolve the welfare losses arising from the digital divide, but also improve social well-being in all regions.

A great many circular RNAs (circRNAs) are considered key modulators of human malignancies. However, the function of circRNA lysophosphatidic acid receptor 3 (LPAR3) in the radioresistance of prostate cancer (PCa) cells is still uncertain. circLPAR3, microRNA (miR)-329-3p, and JPT1 expression in PCa tissues and cells were detected by real-time quantitative PCR or western blot. Cell proliferation was detected by CCK-8 (cell proliferation assay) and colony formation assay, apoptosis was by flow cytometry, and migration and invasion ability were by Transwell assay. Cell glycolysis was analyzed by glucose uptake, lactate production, and ATP metabolism. Under different doses of radiation, the radiosensitivity of PCa cells was detected by colony formation assay. The relationship between circLPAR3, miR-513b-5p, and JPT1 was confirmed by dual luciferase reporter gene detection and RIP assay. The data presented that circLPAR3 and JPT1 expression was elevated in PCa, while miR-513b-5p expression was reduced. Repression of circLPAR3 depressed cell advancement, and restrained glycolysis, but enhanced the radiosensitivity of PCa cells. CircLPAR3’s target miRNA was miR-513b-5p which targeted JPT1. Elevated JPT1 reversed the repressive effects of circLPAR3 knockdown or miR-513b-5p overexpression on PCa advancement, glycolysis, and radiosensitivity. In summary, the knockdown of circLPAR3 reduces glycolysis, but promotes PCa radiosensitivity via the miR-513b-5p/JPT1 axis, discovering a novel mechanism in PCa progression.
