The Corrosion Behaviors of X70 Steel Under the Effect of Alternating Current and Sulfate-Reducing Bacteria in Seawater
Authors: Zhang Shouxin , Yan Jialin , Chen Zhiwei , Huan He , Ye Chunhao
Published: May 2024

The influence of alternating current (AC) and sulfate-reducing bacteria (SRB) on the corrosion behaviors of X70 steel in seawater was investigated by different electrochemical tests and surface examination methods. It was found that the activity of SRB was affected by AC. When the AC current density sustains at the low level of 0  A/m2 and 50 A/m2, the activity of SRB is not high enough to produce a significant impact on the AC-induced corrosion process. As the current density increases to 80 A/m2 and 100 A/m2, SRB could alter the corrosion kinetics by forming a more intact film on the corrosion surface. However, the activity of SRB is inhibited by AC with the current density up to 200 A/m2. The intact corrosion product formed by SRB in high activity could influence the AC corrosion kinetics, but the product film can not prevent AC-induced corrosion. The localized corrosion was more significant under the effect of AC and SRB probably because the biofilm formed by SRB produced uneven electrochemical properties on the corrosion surface.

The Anytime-Valid Logrank Test: Error Control Under Continuous Monitoring with Unlimited Horizon
Authors: ter Schure Judith , Pérez-Ortiz Muriel F. , Ly Alexander , Grünwald Peter D.
Published: May 2024

We introduce the anytime-valid (AV) logrank test, a version of the logrank test that provides type-I error guarantees under optional stopping and optional continuation. The test is sequential without the need to specify a maximum sample size or stopping rule, and allows for cumulative meta-analysis with type-I error control. The method can be extended to define anytime-valid confidence intervals. The logrank test is an instance of the martingale tests based on E-variables that have been recently developed. We demonstrate type-I error guarantees for the test in a semiparametric setting of proportional hazards, show explicitly how to extend it to ties and confidence sequences and indicate further extensions to the full Cox regression model. Using a Gaussian approximation on the logrank statistic, we show that the AV logrank test (which itself is always exact) has a similar rejection region to O’Brien-Fleming α-spending but with the potential to achieve $100\% $ power by optional continuation. Although our approach to study design requires a larger sample size, the expected sample size is competitive by optional stopping.

Flocking Behavior of Boids Driven by Hyperchaotic MACM System
Authors: Medina Ana , Cardoza Avendaño Lılıana , López-gutiérrez Rosa Martha , Cruz Hernández Cesar
Published: May 2024

In the present work a detailed study is presented, on the design, programming, and investigation of the behavior of flocking (Movement type flock), through the model of BOIDS, for its acronym in English "Bird Oid Object" (Object type bird), which was devised by Craig Reynolds in 1986. This complex flocking behavior that occurs arises from the interaction of simple local rules, in which complexity and sensitivity to initial conditions are present. A measure of chaotic compound will be introduced to the algorithm by means of a new four-dimensional autonomous hyperchaotic system based on the 3D Méndez-Arellano-Cruz-Martínez (MACM) system. The measures proposed herein, therefore, may have the potential to predict, control, and exemplify the behavior of group intelligence study systems that occur in nature, allowing the implementation of these systems in groups of robots through the implementation of hyperchaotic trajectories in the future, to obtain greater speed and efficiency, obstacle and collisions avoidance in their flights.

Framing Social Movements on Social Media
Authors: Mendelsohn Julia , Vijan Maya , Card Dallas , Budak Ceren
Published: May 2024

Social media enables activists to directly communicate with the public and provides a space for movement leaders, participants, bystanders, and opponents to collectively construct and contest narratives. Focusing on Twitter messages from social movements surrounding three issues in 2018-2019 (guns, immigration, and LGBTQ rights), we create a codebook, annotated dataset, and computational models to detect diagnostic (problem identification and attribution), prognostic (proposed solutions and tactics), and motivational (calls to action) framing strategies. We conduct an in-depth unsupervised linguistic analysis of each framing strategy, and uncover cross-movement similarities in associations between framing and linguistic features such as pronouns and deontic modal verbs. Finally, we compare framing strategies across issues and other social, cultural, and interactional contexts. For example, we show that diagnostic framing is more common in replies than original broadcast posts, and that social movement organizations focus much more on prognostic and motivational framing than journalists and ordinary citizens.

Abstract. Extreme biomass burning (BB) events, such as those seen during the 2019–2020 Australian bushfire season, are becoming more frequent and intense with climate change. Ground-based observations of these events can provide useful information on the macro- and micro-physical properties of the plumes, but these observations are sparse, especially in regions which are at risk of intense bushfire events. Satellite observations of extreme BB events provide a unique perspective, with the newest generation of geostationary imagers, such as the Advanced Himawari Imager (AHI), observing entire continents at moderate spatial and high temporal resolution. However, current passive satellite retrieval methods struggle to capture the high values of aerosol optical thickness (AOT) seen during these BB events. Accurate retrievals are necessary for global and regional studies of shortwave radiation, air quality modelling and numerical weather prediction. To address these issues, the Optimal Retrieval of Aerosol and Cloud (ORAC) algorithm has used AHI data to measure extreme BB plumes from the 2019–2020 Australian bushfire season. The sensitivity of the retrieval to the assumed optical properties of BB plumes is explored by comparing retrieved AOT with AErosol RObotic NETwork (AERONET) level-1.5 data over the AERONET site at Tumbarumba, New South Wales, between 1 December 2019 at 00:00 UTC and 3 January 2020 at 00:00 UTC. The study shows that for AOT values > 2, the sensitivity to the assumed optical properties is substantial. The ORAC retrievals and AERONET data are compared against the Japan Aerospace Exploration Agency (JAXA) Aerosol Retrieval Product (ARP), Moderate Resolution Imaging Spectroradiometer (MODIS) Deep Blue over land, MODIS MAIAC, Sentinel-3 SYN and VIIRS Deep Blue products. The comparison shows the ORAC retrieval significantly improves coverage of optically thick plumes relative to the JAXA ARP, with approximately twice as many pixels retrieved and peak retrieved AOT values 1.4 times higher than the JAXA ARP. The ORAC retrievals have accuracy scores of 0.742–0.744 compared to the values of 0.718–0.833 for the polar-orbiting satellite products, despite successfully retrieving approximately 28 times as many pixels over the study period as the most successful polar-orbiting satellite product. The AHI and MODIS satellite products are compared for three case studies covering a range of BB plumes over Australia. The results show good agreement between all products for plumes with AOT values ≤ 2. For extreme BB plumes, the ORAC retrieval finds values of AOT > 15, significantly higher than those seen in events classified as extreme by previous studies, although with high uncertainty. A combination of hard limits in the retrieval algorithms and misclassification of BB plumes as cloud prevents the JAXA and MODIS products from returning AOT values significantly greater than 5.

Published: May 2024

Abstract. EISCAT_3D is a project to build a multi-site phased-array incoherent scatter radar system in northern Fenno-Scandinavia. We demonstrate via numerical simulation how useful monochromatic images taken by a multi-point imager network are for auroral research in the EISCAT_3D project. We apply the generalized aurora computed tomography (G-ACT) method to modelled observational data from real instruments, such as the Auroral Large Imaging System (ALIS) and the EISCAT_3D radar. G-ACT is a method for reconstructing the three-dimensional (3D) distribution of auroral emissions and ionospheric electron density (corresponding to the horizontal two-dimensional (2D) distribution of energy spectra of precipitating electrons) from multi-instrument data. It is assumed that the EISCAT_3D radar scans an area of 0.8° in geographic latitude and 3° in longitude at an altitude of 130 km with 10 × 10 beams from the radar core site at Skibotn (69.35° N, 20.37° E). Two neighboring discrete arcs are assumed to appear in the observation region of the EISCAT_3D radar. The reconstruction results from G-ACT are compared with those from the normal ACT as well as the ionospheric electron density from the radar. It is found that G-ACT can interpolate the ionospheric electron density at a much higher spatial resolution than that observed by the EISCAT_3D radar. Furthermore, the multiple arcs reconstructed by G-ACT are more precise than those by ACT. In particular, underestimation of the ionospheric electron density and precipitating electrons' energy fluxes inside the arcs is significantly improved by G-ACT including the EISCAT_3D data. Even when the ACT reconstruction is difficult due to the unsuitable locations of the imager sites relative to the discrete arcs and/or a small number of available images, G-ACT allows us to obtain better reconstruction results.
Plant functional traits modulate the effects of soil acidification on above- and belowground biomass

Published: May 2024

Abstract. Atmospheric sulfur (S) deposition has been increasingly recognized as a major driver of soil acidification. However, little is known about how soil acidification influences above- and belowground biomass by altering leaf and root traits. We conducted a 3-year S-addition experiment to simulate soil acidification in a meadow. Grass (Leymus chinensis (Trin.) Tzvelev) and sedge (Carex duriuscula C.A.Mey) species were chosen to evaluate the linkage between plant traits and biomass. Sulfur addition led to soil acidification and nutrient imbalances. Soil acidification decreased specific leaf area (SLA) but increased leaf dry-matter content (LDMC) in L. chinensis, showing a conservative strategy and thus suppressing aboveground instead of belowground biomass. However, in C. duriuscula, soil acidification increased plant height and root nutrients (N, P, S, and Mn), favoring competition for natural resources through enhanced above- and belowground biomass, i.e., adoption of an acquisitive strategy. Increased soil acidity resulted in an overall reduction in aboveground community biomass by 3 %–33 %, but it led to an increase in community root biomass by 11 %–22 % due to upregulation as a result of higher soil nutrient availability. Our results demonstrate that both above- and belowground plant biomass is affected by S-induced acidification. Understanding the linkage between plant biomass and functional traits contributes to a better understanding of plant–soil feedback in grassland ecosystems.
The energy-efficient reductive tricarboxylic acid cycle drives carbon uptake and transfer to higher trophic levels within the Kueishantao shallow-water hydrothermal system

Abstract. Chemoautotrophic Campylobacteria utilize the reductive tricarboxylic acid (rTCA) cycle for carbon uptake, a metabolic pathway that is more energy efficient and discriminates less against 13C than the Calvin-Benson-Bassham cycle. Similar to other hydrothermal systems worldwide, Campylobacteria dominate the microbial community of the shallow-water hydrothermal system off Kueishantao (Taiwan). Compound-specific carbon stable isotope analyses of lipid-derived fatty acids were performed to understand the importance of rTCA and the transfer of fixed carbon to higher trophic levels in the vent area. Of these, C16:1ω7c, C18:1ω7c, and C18:1ω9 fatty acids were strongly enriched in 13C, indicating the activity of rTCA utilizing Campylobacteria. Isotopic fractionation was close to 0 ‰, likely caused by pH values as low as 2.88. Characteristic fatty acids were present not only in the vent fluids but also in adjacent sediments and water filters 20 m away from the vent orifice, even though with decreasing abundance and diluted 13C enrichment. Furthermore, δ13C analysis of fatty acids from the tissue of Xenograpsus testudinatus, a crab endemic to this particular vent system, identified the trophic transfer of chemosynthetically fixed carbon. This highlights the interrelationship between chemoautotrophic microbial activity and life opportunities of higher organisms under environmentally harsh conditions at shallow-water hydrothermal systems.

Authors: Kozulia Tatiana , Korshunov Svjatoslav
Published: May 2024

The paper provides implementation results of complex ecological control for safety level at technological objects based on European approach which is in fact environmental influence estimation (EIE). Environmental influence estimation system (EIES) has normative approach and is restrictive, so it doesn’t prevent technological pollution of environment. EIES standards are created according to zero human health risk concept, but real insignificant exceedings of critical concentrations are potentially dangerous for ecosystems. «Zero risk» concept doesn’t ensure ecological economy growth, as it is based upon risk analysis principle of «costs-benefits». It narrows application of sustainable development statements and Ecostrategy-2019, which require ecological natural resources usage, anthropogenic environment influence decrease, ecological activity effectiveness parameters increase.
The paper proposes EIE system approach implementation due to complex achieving of economical objects sustainable ecological development. Systemology was examined as base for heterogeneous objects information models creation during interdisciplinary problem solving of complex «object-environment» systems research.
Ecological technological safety at business objects control system creation reasonability is noticed in complex aspect according to strategically ecological estimation. It allows to determine current environment state and planned activity potential influence upon population inside determined area.
Research object is technological safety at business objects ecological control system with dangerous environment influence prevention strategy.
Research subject is technological safety at business objects ecological control system development for petrol station as example.
APPLICATION OF THE PRINCIPLE OF MAXIMUM INFORMATIVENESS WITH MINIMAL EXCESS OF INFORMATION FOR SELECTING THE OPTIMAL NUMBER OF WATER QUALITY PARAMETERS

The quality of surface water plays a vital role in determining the sustainability of the ecological environment, the health of the population, and the socio-economic development of entire countries. Unfortunately, the rapid growth of the world's population together with the current climate change mainly deteriorates the state of surface water bodies. Thus, the use of effective methodologies capable of quickly and easily obtaining reliable information about the quality of surface water becomes fundamental for the effective use of water resources and implementation of mitigation measures and actions. Water pollution indices are one of the most widely used methods for providing a clear and complete picture of the state of river pollution, for the needs of rational water use and sustainable management of water resources. The selection of parameters is one of the most important and difficult stages, and the available statistical methods do not demonstrate great objectivity and accuracy in determining the real state of water quality. a new approach, based on the theory of entropy and known as the principle of maximum informativeness with minimum redundancy of information (MIMH), is proposed for determining the optimal subset of parameters describing the change in the quality level of a water body in space and time and, thus, determining the sources of pollution. The algorithm for the MIMN principle was implemented and applied to three rivers: the Southern Bug, the Dniester, and the Siverskyi Donets.
TECHNIQUE OF LAND RECULTIVATION OF PLACES OF AMMUNITION DISPOSAL AND DESTRUCTION
Authors: Didovets Yurij
Published: May 2024

The relevance of the research and the need to develop methods that allow restoring the lands of the ammunition disposal and destruction sites during the application of measures for their recultivation are shown. The criteria for evaluating the safety level of the process of recultivation of the lands of the ammunition disposal and destruction sites based on the use of a regulatory approach and significant indicators were determined, namely: the probability of an explosion, the amount of excessive pressure in the air shock wave, and the level of degradation of the lands of the ammunition disposal and destruction sites.
For the first time the technique of land recultivation of places of ammunition disposal and destruction was developed. It includes three stages: Stage 1 – monitoring of land of places of ammunition disposal and destruction based on unmanned aviation monitoring system; Stage 2 – demining of land of ammunition disposal and destruction by specialized pyrotechnic units of the State Emergency Service of Ukraine using the results of the monitoring conducted at Stage 1; Stage 3 – biological treatment of land of the ammunition disposal and destruction using the phytoremediation method.
The interactive dimension of mental construal an the participant-setting distinction in the expression of stance
Authors:   Saint-Petersburg State University of Culture, Hrisonopulo Katherine
Published: May 2024

This paper presents an account of the phenomenon of mental construal manifested in English expressions of stance through the distinction of clauses that are headed by subjects associated with two conceptual archetypes: participant (P) invoked by the first-person pronoun (‘I am certain that’) and abstract setting (S) conveyed by anticipatory ‘it’ (‘It is certain that’). With recourse to the main theoretical points on the anchoring of linguistic meaning in the acts of mental construal and interactive coordination, the conducted analysis focuses on a corpus of about 350 examples that represent narrative and dialogic discourse in English-language fiction. It shown that the choice of stance expressions with P- and S-subjects is motivated by the distinctions that arise in discourse between actual and mentally represented types of reality, the contrast between reference-making and viewing as types of cognitive operations and the associated narrative and dialogic strategies.
Cognition énactive en contexte numérique : Affordances des textes multimodaux
Authors:   UNIVERSITÉ DE LORRAINE CREM, Achard-Bayle Guy , Kaced Omar
Published: May 2024

Suivant un cadre cognitif « écologique », nous considérons que le sujet et le monde ne sont pas seulement en interaction mais se co-constituent ; dans ce même cadre, nous considérons que la et la recherche de sens sont d’une part les corrélats d’une intention, d’autre part des sollicitations qu’émettent le ou les référents autres que le sujet, avec lesquels néanmoins ce dernier entre en relation. La question didactique qui se pose dans ce cadre est celle de l’appropriation. Notre article se propose ainsi de rendre compte d’un modèle d’acquisition dans un environnement multimédia qui s’inscrit dans cette perspective de cognition écologique. Dans cette perspective, l’affordance permet de mettre en relation l’outil, l’apprenant et l’environnement d’apprentissage : il en résulte une ou des interactions entre les propriétés constitutives du premier, les conditions de l’expérience en situation, et les perceptions et les besoins du sujet. Dans ces conditions, d’apprentissage et d’expérimentation, la question que nous serons amenés à nous poser est la suivante : quels sont la place, le rôle, l’impact du texte omniprésent dans les environnements TIC multimodalisés et multicanalisés ?
Esquisse des principes d’une chronosignifiance
Authors:   ERIMIT/ERILIIS, Université Rennes 2 Université Lille 3, Poirier Marine
Published: May 2024

À rebours d’une approche communément admise de la phrase qui y voit l’agencement spatial d’objets préconstruits en fonction de règles de combinaison, cet article se fixe pour objectif de poser les premiers jalons d’une chronosignifiance, approche temporalisée de la construction des signifiants qui méthodologiquement recouvre l’étude des parcours de coalescence, d’unification et de distinction par lesquels ces derniers se morphologisent en temps réel au fil de l’énoncé. On présente la posture phénoménologique inspirée de l’énaction qui tout à la fois la sous-tend et à laquelle elle invite, ainsi que son fonctionnement méthodologique en espagnol.
Ko, ningo, luego : an enactive approach to the emergence of an epistemic subsystem in jopara
Authors:   EA 7345 CLESTHIA Université Sorbonne Nouvelle, Blestel Élodie
Published: May 2024

Paraguay’s two co-official languages, Spanish and Guarani, have experienced close, extended contact. This has contributed to the emergence of dialectal variants known as « Jopara », in which units from both languages alternate. In this paper, we put forth the view that the alternation, in Jopara Spanish, of the discourse markers ko, ningo (both of Guarani origin), and luego (from Spanish) is the manifestation of a new epistemic subsystem based on the reanalysis of « biomechanically embodied » cognitive operators (Bottineau 2012), which are incorporated into a semiological network that transcends this semantic field alone. Our corpus is composed of excerpts from the online discussion forums of the newspaper Hoy, which belongs to the Multimedia group located in Asunción (Paraguay).

Published: May 2024

This research presents a comprehensive analysis of Bael guda prices in Central India over a 12-year period, spanning 2010-2014 and 2015-2021. The study delves into the intricate details of pricing dynamics, regional variations, and temporal fluctuations within the Bael guda market. Quarterly price data was collected from various markets, including regional and district levels, to analyze long-term market patterns and price trends. The research highlights the regional disparities in Bael guda pricing, with Shivpuri consistently emerging as the district with the highest average prices, underscoring the influence of factors such as local availability, demand dynamics, and transportation costs on pricing variations. Additionally, the study offers insights into the stability and variability of prices, with the 2015-2021 period exhibiting greater fluctuations, as indicated by higher standard deviations and coefficient of variation values. Furthermore, the research evolves price growth patterns, with remarkable growth rates in certain markets, such as Mandla, Dhamtari and Sheopur (M.P.). This comprehensive analysis not only enhances our understanding of the economic aspects of the Bael guda trade but also provides valuable insights for market stakeholders and policymakers, facilitating informed decision-making in this niche market.
