« Ceci n’est pas un traité ». Umberto Eco parmi les manuels de sémiotique
Authors: Marrone Gianfranco
Published: January 2024

Qu’est-ce qu’un Trattato ? Quelles sont ses formes textuelles ? Et quels sont ses objectifs de communication ? Bien qu’il existe de nombreux livres dans le monde qui présentent la sémiotique, le Trattato di semiotica generale d’Eco est le seul qui utilise, dans son titre, ce terme philosophique. En analysant la préface du livre, il est clair que le Trattato pourrait en fait servir d’essai théorique. En analysant plutôt sa structure argumentative, on se rend compte que le ton général du livre est narratif.
Intramolecular London Dispersion Interactions in Single-Molecule Junctions
Authors: Hight Matthew O. , Wong Joshua Y. , Pimentel Ashley E. , Su Timothy A.
Published: January 2024

This manuscript shows the first example of using intramolecular London dispersion interactions to control molecular geometry and quantum transport in single-molecule junctions. Flexible σ-bonded molecular junctions typically occupy straight-chain geometries due to steric effects. Here we synthesize a series of thiomethyl-terminated oligo(dimethylsilmethylene)s that bear [CH2-Si(CH3)2]n repeat units, where all backbone dihedral states are sterically equivalent. Scanning tunneling microscopy break-junction (STM-BJ) measurements and theoretical calculations indicate that in the absence of a strong steric bias, concerted intramolecular London dispersion interactions staple the carbosilane backbone into coiled conformations that remain intact even as the junction is stretched to its breakpoint. As these kinked conformations are highly resistive to electronic transport, we observe record-high conductance decay values on an experimental junction length basis (β = 1.86 ± 0.12 Å-1). These studies reveal the potential in using intramolecular London dispersion interactions to design single-molecule electronics.
JEDI: A versatile code for strain analysis of molecular and periodic systems under deformation

Published: January 2024

Stretching or compression can induce significant energetic, geometric and spectroscopic changes in materials. To fully exploit these effects in the design of mechano- or piezochromic materials, self-healing polymers, and other mechanoresponsive devices, a detailed knowledge about the distribution of mechanical strain in the material is essential. Within the past decade, the Judgement of Energy DIstribution (JEDI) analysis has emerged as a useful tool for this purpose. Based on the harmonic approximation, the strain energy in each bond length, bond angle and dihedral angle of a deformed system is calculated using quantum chemical methods. This allows the identification of the force-bearing scaffold of the system, leading to an understanding of mechanochemical processes at the most fundamental level. Here we present a publicly available code that generalizes the JEDI analysis, which has previously only been available for isolated molecules. Now the code has been extended to two- and three-dimensional periodic systems, supramolecular clusters, and substructures of chemical systems under various types of deformation. Due to the implementation of JEDI into the Atomic Simulation Environment (ASE), the JEDI analysis can be interfaced with a plethora of program packages that allow the calculation of electronic energies for molecular systems and systems with periodic boundary conditions. The automated generation of a color-coded three-dimensional structure via the Visual Molecular Dynamics (VMD) program allows insightful visual analyses of the force-bearing scaffold of the strained system.
Exploring Transition States of Protein Conformational Changes via Out-of-Distribution Detection in the Hyperspherical Latent Space

Published: January 2024

Identifying transitional states is crucial for understanding protein conformational changes that underlie numerous fundamental biological processes. Markov state models (MSMs) constructed from Molecular Dynamics (MD) simulations have demonstrated considerable success in studying protein conformational changes, which are often associated with rare events transiting over free energy barriers. However, it remains challenging for MSMs to identify the transition states, as they group MD conformations into discrete metastable states and do not provide information on transition states lying at the top of free energy barriers between metastable states. Inspired by recent advances in trustworthy artificial intelligence (AI) for detecting out-of-distribution (OOD) data, we present Transition State identification via Dispersion and vAriational principle Regularized neural neTworks (TS-DART). This deep learning approach effectively detects the transition states from MD simulations using hyperspherical embeddings in the latent space. The key insight of TS-DART is to treat the transition state structures as OOD data, recognizing that the transition states are less populated and exhibit a distributional shift from metastable states. Our TS-DART method offers an end-to-end pipeline for identifying transition states from MD simulations. By introducing a dispersion loss function to regularize the hyperspherical latent space, TS-DART can discern transition state conformations that separate multiple metastable states in an MSM. Furthermore, TS-DART provides hyperspherical latent representations that preserve all relevant kinetic geometries of the original dynamics. We demonstrate the power of TS-DART by applying it to a 2D-potential, alanine dipeptide and the translocation of a DNA motor protein on DNA. In all these systems, TS-DART outperforms previous methods in identifying transition states. As TS-DART integrates the dimensionality reduction, state decomposition, and transition state identification in a unified framework, we anticipate that it will be applicable for studying transition states of protein conformational changes.
Unveiling the Multifaceted Nature of 4-(4-MethylphenylThio)benzophenone: A Combined DFT, NBO, and Spectroscopic Investigation of its Electronic Structure and Excited States
Authors: BHATIA MANJEET
Published: January 2024

Benzophenone and its derivatives are some of the most widely employed as UV (ultra-violet) lters and UV-ink photoinitiators. Photoinitiating properties of benzophenones are mainly attributed to the extent of π -conjugation and the amount of delocalization in the molecule. By understanding the interplay of conjugation, delocalization, and substituent effects, photo initiating properties of benzophenone derivatives can be ne-tuned for speci c applications. Using quantum mechanical calculations based B3LYP/6-311++G(d, p) density functional theory (DFT), chemical reactivity, stability, and photointitiating properties are computed for 4-4 (methylphenylthio)benzophenone. Proton affinity, ionization energy, electron affinity, reactivity, and spectroscopic properties are computed. DFT computed infrared spectra aligned with the available experimental results. UV/ Visible spectra demonstrate absorption towards higher wavelength region due to the extended delocalization of π-electrons. This knowledge empowers the design of novel initiators with tailored light absorption, excited state life times, and reaction selectivities, opening doors to advantages in UV-curing, photopolymerization, and other light-driven processes.

Mucus is a complex biological hydrogel that acts as a barrier for almost everything entering or exiting the body. It is therefore of emerging interest for biomedical and pharmaceutical applications. Besides water, the most abundant components are the large and densely glycosylated mucins, a family of glycoproteins with sizes of up to 20 MDa and a carbohydrate content of up to 80 wt%. Here, we designed and explored a library of glycosylated peptides to deconstruct the complexity of mucus. By using the well characterised hFF03 coiled-coil system as a hydrogel-forming peptide scaffold, we systematically probed the contribution of single glycans to the secondary structure as well as the formation and the viscoelastic properties of the resulting hydrogels. We show that glycan-decoration does not affect α helix and coiled-coil formation while it alters gel stiffness. By using oscillatory macrorheology, dynamic light scattering microrheology and fluorescence lifetime-based nanorheology, we characterised the glycopeptide materials over several length scales. Molecular simulations revealed that the glycosylated linker may extend into the solvent, but more frequently interacts with the peptide, thereby likely modifying the stability of the self-assembled peptide fibres. The results of this systematic study highlight the interplay between glycan structure and hydrogel properties and may guide the development of synthetic mucus mimetics.

Authors: Ratna K.
Published: January 2024

Interfaces, where different fluids meet, are crucial zones influencing processes like emulsification and foam creation. Understanding their properties is vital in chemical, biosciences and oil industry. Rheology, evaluating stress and strain, helps characterize these properties, distinguishing between material behavior like elasticity and viscosity. Stress causes deformation, crucial in defining a material's response. Elastic materials return to shape after stress, maintaining ratios. Interfacial studies benefit diverse fields like engineering, biology, and medicine, unveiling unique properties for material design. In biology, studying bio-interfaces elucidates complex cell behaviors and drug delivery. Recent research emphasizes the importance of studying interfaces. Peptide interfaces exhibit self-organization in cell elongation, while motor protein-based nano-biodevices and antimicrobial implant surfaces demonstrate new applications. Interfacial studies impact nanocomposites, dental materials, cancer stem cells, and nanospheres, showcasing their broad implications in diverse fields. Nanotechnology combined with biology creates new medical possibilities. Nanomedicine, using nanoparticles, shows promise in drug delivery and cancer treatment. Challenges exist in understanding bio-interfaces, crucial for medical progress. Advances in nanotech and interfacial studies could transform fields with ongoing research needed for big changes.
Flow characteristics of injection water outlets-regulators
Authors:   Timirâzevskaâ selʹskohozâjstvennaâ akademiâ, Snezhko Vera Leonidovna
Published: January 2024

In cases where the supply of energy sources to hydraulic structures located on irrigation canals is economically unjustified, hydraulic automation means are widely used in Russia and abroad. The purpose of the research is to derive design dependencies to determine the flow rate of the injected and injected flows, taking into account hydraulic losses within the flow path of the structure, to construct the flow characteristic of the regulator with a nozzle and an output section of a constant area with its subsequent verification by the data of the hydraulic experiment. Injection flow regulators have several modifications: with a diffuser outlet section without restricting the outlet pipe with a nozzle, with a nozzle and diffuser, with a nozzle and an outlet section of a constant area. For regulators with a nozzle, dependences for hydraulic calculations have now been obtained, which can be considered conditionally “ideal”, since they do not take into account a number of local resistances and frictional resistances along the length that arise when flows merge with subsequent movement in the mixing chamber. As a result of the research, the authors for the first time obtained calculated dependencies for determining the flow rate of the injected and injected flows, taking into account hydraulic losses within the flow path of the structure, and constructed the flow characteristic of a regulator with a nozzle and an outlet section of a constant area. The flow characteristic is verified using available hydraulic experiment data. An analysis of the shape of the flow characteristics of the injection regulator was carried out by comparison with the generalized characteristics of hydraulic jet pumps. The practical significance of the research lies in the possibility of using the dimensionless characteristics of the injection water outlet to link it to specific operating conditions, as is customary when selecting pumps. To determine the flow rates in the regulator, a computer program has been registered.

The purpose of the research is to analyze the practice of organizing wood harvesting in the East Siberian taiga-permafrost forest area. The methodological basis was the methods of comparative analysis and evaluation, which include the collection and analysis of the main activities of logging production. The East Siberian taiga-permafrost forest area is 112 million hectares, with a total wood reserve of 7240.52 million m3. The forest area is characterized by a low intensity of forest use. The weak development of the road network is noted. A significant part of the wood is harvested when using forests for mining and construction of linear objects. The size of the estimated cutting area during the cutting of ripe and overgrown forest stands amounted to 35447.62 thousand m3, while the volume of the actual used estimated cutting area is 1151.54 thousand m3. It uses an average of 3.2% of the permissible forest use index. The main reserves of business timber, as well as large production facilities for its processing, are concentrated in the Republic of Sakha (Yakutia) – in the Aldan (36.9 million m3), Gorny (291.2 million m3), Lensk (923.7 million m3), Olek-Minsk (1170.8 million m3) forestry, which account for more than 50% of the annual estimated cutting area.

Published: January 2024

The aim of the study is to assess the impact of irrigation with wastewater of various degrees of treatment from urban wastewater treatment plants on agrochemical indicators of soils. As materials for the study, samples of wastewater of various degrees of treatment were selected (stage 1 – mechanical treatment, stage 2 – biological treatment) from the Kadamovsky treatment facilities of LLC “Ecological Technologies” in Novocherkassk. The selected samples were evaluated according to the main irrigation indicators: irrigation coefficient, sodium adsorption coefficient and the danger of magnesium salinization. Under laboratory conditions, alfalfa seeds were grown in vessels against the background of irrigation with tested waters. Agrochemical indicators of soils were evaluated in comparison with the approved standards for soils of the Rostov region. The control sample was watered with water from the Don River. Irrigation characteristics of the selected wastewater samples demonstrate their suitability for irrigation in all controlled parameters. In both types of treated wastewater, there is an excess of the content of phosphates by more than 30 times compared to the established norms, sulfates – by more than 4 times. As a result of the soil assessment, the following data were obtained: the humus content after irrigation with wastewater that has undergone only mechanical treatment increased slightly, in other cases the amount of humus decreased, and in the control variant by 1.5 times, and in the variant with water after biological treatment by only 6%; in all variants, when irrigation with wastewater, it is noted accumulation of nitrogen, as well as in all variants, there is a decrease in the content of phosphates and potassium in soils. The change in electrical conductivity indicates the leaching of easily soluble salts from soils against the background of irrigation, and to the greatest extent when watering with water that has passed the 2nd stage of treatment. In general, according to all indicators, the most suitable for irrigation is water after biological treatment

Information about the irrigation process goes to the central fail-safe server of the system, where it is processed and entered into the database, which can be integrated into the accounting system of the enterprise. It has been established that the introduction of sprinkler machines “Cascade 65T” and the universal control and monitoring system on the agricultural enterprise will bring to unified management of sprinkler machines and pumping stations. This in turn will ensure the coordinated operation of sprinkler machines and optimal distribution of loads on the pumping stations.
Peculiarities of the design of drive elements for electric circular sprinkling machines
Authors:   Timirâzevskaâ selʹskohozâjstvennaâ akademiâ, Bashmakov Igor Andreevich
Published: January 2024

Land irrigation is one of the important factors in obtaining stable and high crop yields. In Russia, up to 80% of arable land is located in zones of insufficient and unstable soil moisture. Sprinkler machines are used to irrigate the soil. Manufacturers of sprinkler equipment offer a wide range of machines to work on closed irrigation networks. Angular transmission (AT) is most commonly used as the wheel gear of sprinkler machines. An important component of the wheel gearbox is the worm gear. When analyzing the existing designs of arch sprinkler carts, it was concluded that it is necessary to optimize some of its elements. Such an element, in our opinion, is the elastic element of the coupling, made of polymeric material. The force elements of the elastic insert work mainly in bending. The most dangerous part of this element is the base of the “tooth”. In most cases, this element provides the necessary performance of the sprinkler drive, but at the peak values of torque (movement of wheeled cart on a difficult section) its deformation due to insufficient strength is possible. Therefore, the purpose of our work is to improve the strength characteristics of the drive elements of the arch-type sprinkler cart by optimizing their design parameters. To calculate the loads on the gearbox, classical methods of calculation of worm gears were used, taking into account the coefficients that depend on the environment. The finite element method with the use of the software environment Compass 3D was used to manufacture the prototype on a 3D printer.

Published: January 2024

The purpose of this work was to perform information modeling (creation of a “digital twin”) of a section of the water reclamation system located in the floodplain of the Oka River on the territory of the Kolomna City District of the Moscow Region, in the environment of the Google Earth and QGIS geo-information system, and assess its technical and environmental condition. Established groups of technical and environmental conditions allow to formulate a hypothesis about the vector of changes in the life cycle stage of the water reclamation system for the worse. It is noted that the accuracy of such an assessment according to GOST R70611‑2022 depends primarily on how much the initial information reveals the indicators of technical and environmental condition, as well as the presence of retrospective information about the object. As a result of information modeling of the reclamation facility, a group of its technical and environmental conditions was established. At the same time, the assessment by remote methods cannot be final, and the formulated hypothesis about the vector of change in the life cycle stage of the water reclamation system serves as a marker for making the necessary decisions regarding the need for its detailed field examination.

The results of chemical analyses showed a difference in the characteristics of rainwater collected from roofs, roads and courtyards. Based on the qualitative composition of rainwater, it was found that rainwater collected from roofs has the least pollution. Technological features of rainwater collection and treatme nt for their further reuse are described. It is proposed to create an accumulating reservoir, the replenishment of which will be carried out as it is used, taking into account the calculated values of the basic techniques. A technological scheme for the treatment of rainwater collected from roofs has been developed, the simplicity and cheapness of the proposed technology is noted.

O objetivo deste foi investigar a efetividade da Resolução nº 002/2019 do Conselho Estadual de Educação de Mato Grosso e a legislação brasileira que regem o ensino para alunos refugiados no Brasil, sob a óptica dos professores e gestores. O início da proposta metodológica compreendeu o processo de leitura de documentos que regem a Educação para alunos refugiados; e de levantamento dos dados, através da distribuição de questionários elaborados no Google Forms (enviados nos e-mails institucionais). Após a devolução com as respostas, separou-se os dados em categorias e aplicou-se os critérios de inclusão e exclusão estabelecidos no projeto. Depois disso, analisou-se e discutiu-se os resultados, apresentando, assim, reflexões, desafios e recomendações para que se possa expandir o tema; para que se proporcione a criação de políticas públicas que atendam efetivamente os direitos educativos e humanos dos estudantes refugiados venezuelanos.

Tecnologias na formação inicial do professor que ensina(rá) Matemática
Authors: Oliveira Carloney Alves de , Martins Sónia Matilde Pinto Correia
Published: January 2024

Este artigo constitui uma reflexão acerca da formação inicial dos futuros professores de Matemática em duas universidades, uma no Brasil e outra em Portugal. A análise incide na forma como se equaciona a formação destes professores no âmbito do uso de tecnologias para o ensino e para a aprendizagem da Matemática. A análise preliminar feita aos dois contextos permite concluir que as práticas desenvolvidas com os futuros professores de Matemática assenta no pressuposto de que a integração da tecnologia deverá contribuir para o surgimento de diferentes práticas inovadoras e colaborativas que favorecem o processo de ensino e de aprendizagem, nas quais os sujeitos envolvidos podem expressar-se, opinar, buscar e receber informações de interesse, colaborar e gerar conhecimento através da diversas experiências socializadas.

This study aims to track and shoot targets with a gun mounted on a quadruped robot in rough terrain and different environmental conditions for increase deterrence in defense. The dynamic movements of the system were modelled as planarly and it was used in walking movement. PID control was used for control the robot leg joints while walking. Because of the walking motion, the success of the target tracking and shooting simulations was examined under the disruptive effects. In order to track the targets whose coordinates were randomly determined and the elevation angle was calculated. It was observed that the robot tracked the targets at 3°, 6° and 9° with a maximum error of 0.6°. In addition, shootings were made to fixed targets located at 10 different coordinates. It was seen that the maximum shooting error value was 16 cm. So, this study will make important contributions to the defense industry.
Confidence Interval Approach to Weather Forecasting with Horizon Based Genetic Programming
Authors: MİNTEMUR Ömer
Published: January 2024

Being able to forecast events has always been important for humans. Humans did forecasting by inspecting movements of material and non-material objects in ancient times. However, thanks to the technological developments and the increasing amount of data in recent years, forecasting is now done by computers, especially by machine learning methods. One of the areas where these methods are used frequently is numerical weather forecasting. In this type of forecast, short, medium and long-term weather forecasts are made using historical data. However, predictions are inherently error-prone phenomena and should be stated which error range the predictions fall. In this study, numerical weather forecasting was done by combining Genetic Programming and Inductive Conformal Prediction method. The effect of 10 and 20 days of historical data on short (1-day), medium (3-days) and long-term (5-days) weather forecasts was examined. Results suggested that Genetic Programming has a good potential to be used in this area. However, when Genetic Programming was combined with the Inductive Conformal Prediction method, it was shown that forecasts gave meaningful results only in short-term; forecasts made for medium and long-term did not produce meaningful results.
Acting on the TRC Calls to Action through education

In this article, the authors share insights from a project focused on building connections between Indigenous and non-Indigenous peoples, communities, and schools. As an Indigenous and non-Indigenous educator team, we suggest that there are various entry points into the work of reconciliation and share our Approaches to Reconciliation model along with several other resources we have found foundational in this work. We conclude by asking the reader to consider which entry point they will begin with.
Examining Cultural Barriers to Teaching Anti-Racist History in the Rural U.S.
Authors: Washington Elizabeth , Seay Travis
Published: January 2024

Although research on teaching about race and racism in rural schools is scant, a handful of studies indicate that race matters a great deal in rural history education. It matters particularly in terms of divergent cultural memories and uses of history (cf. Nordgren, 2016; Seay, 2019) that students and teachers may bring to the classroom. This paper summarizes studies of rural white history teachers who contended with narratives of white dominance in the school and community (cf. Castagno, 2014; Leonardo, 2009, 2013; Vaught, 2011). The teachers faced unforeseen difficulties engaging students in sensitive topics, such as racialized violence and other historical systems of inequality that remain in the present.
