Beyond Life Years Lost, Using Different Outcomes for Population Modelling in Tobacco Harm Reduction
Authors: Prasad Krishna , Hill Andrew , Fiebelkorn Stacy , Edward Lauren
Published: January 2025

Evaluating the reduced-risk potential of novel tobacco and nicotine products, as compared to cigarettes, requires consideration not only of individual risk but also the impact on the population as a whole. Where the reduction in health risk for smokers who switch to the product instead of continuing to smoke, but also the product’s potential effects and rate of uptake among non-smokers must be taken into account.

Computational models have proven to be a valuable tool to enable evaluation of long-term population health effects, in the absence of epidemiological data. Most population health models projecting the health impact of novel tobacco and nicotine products have primarily focussed on potential population harm or benefit using premature ‘all cause’ mortality rates attributable to cigarette smoking as the key output indicator. This study expands on previous mortality projections for the introduction of tobacco heated products (THPs) in Japan, using an enhanced systems dynamics model including non-mortality outcomes. This enables investigation of additional projections for person-years lived with disabilities, tobacco related disease incidence, tobacco use prevalence and tobacco user behaviour, such as average smoker age, the number of years smoked and the age at which individuals ceased smoking. Disease specific projections are provided for the main smoking related diseases, lung cancer, CVD and COPD, and also for esophageal cancer and lower extremity peripheral arterial disease as examples of the potential wider application of this modelling approach.

Modelling estimates based on the available data, indicate that the introduction of THPs into the Japanese marketplace will reduce future smoking prevalence, smoking-related premature deaths and the burden of smoking related disabilities, compared to a scenario where THPs had not been introduced. The resulting projections demonstrate the ability to investigate population health impacts beyond all-cause mortality to provide further insight into the harm reduction potential of alternative nicotine products such as THPs.

Authors: Zakiyyah Abqorry , Bahri Susila
Published: January 2025

This research introduced a nonlinear deterministic model known as SLARS (Susceptible, Light Users, Addicted, and Reformed Users) along with a stability analysis to investigate the dynamics of drug abuse transmission. The basic reproduction number (R0) was calculated using the next-generation matrix method. Following this, the study examined the local stability of both the drug abuse-free and endemic equilibrium points. The findings indicated that when R0 is below 1, the drug abuse-free equilibrium point is locally stable. In contrast, when R0 is greater than 1, the endemic equilibrium point shows local stability. Additionally, simulation results supported the analytical conclusions of the study.
Optimizing the Supply Chain for Recycling Electric Vehicle NMC Batteries
Authors: Kasy Fransisca Indraningsih , Hisjam Muhammad , Jauhari Wakhid Ahmad , Syed Hassan Syed Ahmad Helmi
Published: January 2025

The rapid growth of electric vehicle production has led to increased waste batteries that can no longer be used. This increase causes environmental and economic challenges. Lithium-ion battery waste harms the environment as it contains toxic and ﬂammable chemicals. New raw materials need to be procured economically due to the need for more infrastructure and a circular economy. Therefore, the solution to overcome the impact of the accumulation of lithium battery waste is to recycle the battery. Recycling end-of-life batteries is necessary to mitigate material supply risks, reduce demand for new materials, and mitigate harmful environmental and health impacts. This study aims to provide a conceptual model for the supply chain network design of electric vehicles' Nickel Manganese Cobalt (NMC) battery recycling process. We developed a mathematical model to determine the allocation of multi-product recycling products from multi-suppliers and other related entities such as manufacturers and landﬁlls over multiple periods. The analysis method utilizes techno-economic investment feasibility analysis and load distance method. The problem in the recycling process supply chain network is formulated in a Mixed Integer Linear Programming (MILP) model. The MILP optimization results show that the proposed model produces a globally optimal solution for allocating NMC batteries. The application of this study is to provide a solution to the treatment of waste batteries from electric vehicle end-users in Java Island, Indonesia. In addition, it can develop economic opportunities in the waste battery recycling business in the electric vehicle industry. It is building a contribution to a sustainable electric vehicle battery management system by reducing the dependence on demand for new materials from mining and analyzing the sustainability of the NMC electric vehicle battery recycling process.
Los Juegos Olímpicos y Paralímpicos: un vínculo entre deporte, religión e Inteligencia Artificial a través del cuerpo humano
Authors: García-Antón Palacios Elena
Published: January 2025

A lo largo de la Historia, el deporte y la religión han caminado de la mano desde sus orígenes. Heracles en la antigua Grecia y los atletas olímpicos y paralímpicos en nuestros días simbolizan la superación personal y la lucha por ser los mejores en las grandes competiciones donde se ponen a prueba los límites del cuerpo humano. Así, el lema olímpico “Citius, Altius, Fortius” enfatiza estas inclinaciones. Teniendo en cuenta que, junto a este lema que personifica las aspiraciones de los atletas que participan en los Juegos, la Carta Olímpica sitúa en el centro de su labor la dignidad humana, analizaremos de qué manera se conjugan en nuestros días el factor religioso, el uso de la Inteligencia Artificial y las nuevas tecnologías en los Juegos Modernos a través del respeto a la dignidad y el cuerpo humanos.
Trouver sa place au sein du monde. Quand l’océan accueille les corps meurtris : les expériences sensibles de handi surf
Authors: Sayeux Anne-Sophie
Published: January 2025

Cet article adopte un point de vue anthropologique pour explorer la place des individus affectés par des déficiences corporelles au sein de notre société, en s’appuyant sur une ethnographie du handi surf. En examinant ces dynamiques entre trois niveaux d’analyse : le corps, la nature et le monde, il vise à comprendre la transformation d’un corps meurtri « endormi » à un corps marin qui s’éveille à travers le contact avec la nature. Dans une perspective d’écologie corporelle, ce texte propose une alternative au principe normatif qui enferme les individus dans la catégorie de « personne handicapée ». En mettant l’accent sur les capacités et sur les sensorialités maritimes, qui fondent l’identité « surfeur.se », il présentera de quelle façon l’expérience de l’immersion dans l’océan offre une autre possibilité : celle d’être au cœur du cosmos non plus dans ses limitations, mais bien dans ses capacités.
El concepto paulino del cuerpo agonístico
Authors: Martín Martínez Alodia , Jodra Guillermo
Published: January 2025

En el presente artículo recuperamos la longeva tradición del agón, del combate y la competición, griego en tanto que vehículo idóneo para formular una teoría del cuerpo que, a diferencia del moralismo helenístico y parte del pensamiento del Segundo Templo, a un tiempo recupera, reinterpreta y reemplaza la construcción agonística del cuerpo en la tradición clásica. Defendemos que el corpus paulino trasciende el esquema clásico del protagonista y el antagonista para formar una teoría relacional del cuerpo agonista en que cuerpo y alma espejan el modelo relacional de las personas divinas.

Objetivo: Dado o uso generalizado de bisfosfonatos (BF) para o tratamento de condições como osteoporose e metástases ósseas, e a necessidade de prevenir a osteonecrose dos maxilares induzida por bisfosfonatos (ONM), é essencial entender seu impacto na terapia pulpar vital (TPV). Métodos: Este estudo avaliou a resposta pulpar e periapical, bem como a capacidade de reparo do capeamento pulpar direto (CPD) em um modelo animal pré-tratado com bisfosfonatos. Utilizando 36 molares inferiores de 18 ratos Wistar, os animais foram divididos com base no material restaurador (MTA ou Cotosol) e no tratamento farmacológico (Ácido Zoledrônico ou solução salina). Resultados: O grupo ZA + MTA demonstrou os melhores resultados, com 44,5% de inflamação leve (p=0,033), 88,9% de ausência de patologia periapical (p=0,034) e 55,6% de formação leve de ponte dentinária (p=0,01). Além disso, 33,3% do grupo manteve a morfologia tecidual normal (p=0,024), com a menor ocorrência de calcificação distrófica (37,5%) (p=0,032). Conclusão: Os resultados sugerem que o MTA reduz o infiltrado inflamatório, promove a formação de dentina e favorece a saúde periapical, mesmo na presença de bisfosfonatos. Estes achados destacam o potencial do MTA em mitigar os efeitos adversos dos bisfosfonatos na cicatrização pulpar e periapical.

Published: January 2025

Objetivo: Relatar evidências científicas acerca da importância das bactérias láticas e a influência da adição de fermento endógeno (pingo), durante o processo de maturação de queijos artesanais. Revisão bibliográfica: O tempo de maturação de queijos artesanais, é um tema bastante discutido na literatura, por não haver critérios específicos na produção, resultando em múltiplas interpretações de dados. A ausência de padronização, pode resultar, em produtos menos seguros para o consumo e queda na qualidade. Queijos artesanais resultam de produção peculiar, envolvendo uma microbiota endógena da matéria prima (leite cru refrigerado), que deverá ser de boa qualidade, somada à aplicação das boas práticas de fabricação, o que irá conferir ao produto final, atributos sensoriais específicos como, aroma, sabor e textura. Neste contexto as bactérias láticas, desempenham papel importante na fermentação e preservação de queijos, sendo oriundas da microbiota autóctone da matéria prima, ou, culturas iniciadoras, adicionadas sob condições controladas. Considerações finais: Culturas starters, como o pingo, quando comparadas à fermentação espontânea, podem proporcionar melhor controle da fermentação, redução no tempo de maturação, inviabilidade de microrganismos deteriorantes e patogênicos, como Listeria monocytogenes, assim como aumento da vida útil.
ART-SM: Boosting Fragment-based Backmapping by Machine Learning
Authors: Pfaendner Christian , Korn Viktoria , Gogoi Pritom , Unger Benjamin , Pluhackova Kristyna
Published: January 2025

In sequential multiscale molecular dynamics simulations, which advantageously combine the increased sampling and dynamics at coarse-grained resolution with the higher accuracy of atomistic simulations, the resolution is altered over time. While coarse-graining is straightforward once the mapping between atomistic and coarse-grained resolution is defined, reintroducing the atomistic details is still a non-trivial process called backmapping. Here, we present ART-SM, a fragment-based backmapping framework that learns from atomistic simulation data to seamlessly switch from coarse-grained to atomistic resolution. ART-SM requires minimal user input and goes beyond state-of-the-art fragment-based approaches by selecting from multiple conformations per fragment via machine learning to simultaneously reflect the coarse-grained structure and the Boltzmann distribution. Additionally, we introduce a novel refinement step to connect individual fragments by optimizing specific bonds, angles, and dihedral angles in the backmapping process. We demonstrate that our algorithm accurately restores the atomistic bond length, angle, and dihedral angle distributions for various small and linear molecules from Martini coarse-grained beads and that the resulting high-resolution structures are representative of the input coarse-grained conformations. Moreover, the reconstruction of the TIP3P water model is fast and robust, and we demonstrate that ART-SM can be applied to larger linear molecules as well. To illustrate the efficiency of the local and autoregressive approach of ART-SM, we simulated a large realistic system containing the surfactants TAPB and SDS in solution using the Martini3 force field. The self-assembled micelles of various shapes were backmapped with ART-SM after training on only short atomistic simulations of a single water-solvated SDS or TAPB molecule. Together, these results indicate the potential for the method to be extended to more complex molecules such as lipids, proteins, macromolecules, and materials in the future.
Bayesian Illumination: Inference and Quality-Diversity Accelerate Generative Molecular Models
Authors: Verhellen Jonas
Published: January 2025

In recent years, there have been considerable academic and industrial research efforts to develop novel generative models for high-performing, small molecules. Traditional, rules-based algorithms such as genetic algorithms [Jensen, Chem. Sci., 2019, 12, 3567-3572] have, however, been shown to rival deep learning approaches in terms of both efficiency and potency. In previous work, we showed that the addition of a quality-diversity archive to a genetic algorithm resolves stagnation issues and substantially increases search efficiency [Verhellen, Chem. Sci., 2020, 42, 11485-11491]. In this work, we expand on these insights and leverage the availability of bespoke kernels for small molecules [Griffiths, Adv. Neural. Inf. Process. Syst., 2024, 36] to integrate Bayesian optimisation into the quality-diversity process. This novel generative model, which we call Bayesian Illumination, produces a larger diversity of high-performing molecules than standard quality-diversity optimisation methods. In addition, we show that Bayesian Illumination further improves search efficiency com- pared to previous generative models for small molecules, including deep learning approaches, genetic algorithms, and standard quality-diversity methods.
The Mechanism of Acetyl-CoA Synthase Through the Lens of a Nickel Model System
Authors: Nath Shounak , Griego Leonel , Mirica Liviu
Published: January 2025

Given the urgent need to develop new methods of CO2/CO utilization, understanding the mechanism of acetyl-CoA synthase (ACS) – a primordial nickel enzyme that converts these gases into a source of cellular energy, is crucial; however, conflicting hypotheses and a dearth of well-characterized bioorganometallic intermediates have hindered a proper understanding of its mechanism. Herein, we report a functional model system that supports several organometallic intermediates proposed for ACS, including the long sought-after Ni(methyl)(CO) species, and promotes all key reaction steps during catalysis: methylation, carbonylation, and thiolysis. Our investigations provide key mechanistic insights that are directly relevant to ACS, suggesting that binding of a second CO molecule to the Ni center promotes migratory insertion, that one-electron oxidation of Ni drives a fast reductive elimination, that both paramagnetic and diamagnetic Ni intermediates are involved, and confirm the feasibility of a random binding order of the methyl and CO groups to the Ni center.
Visual monitoring of biomolecular self-assembly dynamics and imaging of protein aggregates by distinct emission of a unique hydrophobic carbon dot
Authors: Bagchi Debanjan , Maity Avijit , Saini Khushwant , Tabassum Huma , Nath Priyanka , Vishwakarma Sachin , Chakraborty Anjan
Published: January 2025

Here, we report a novel and unique application of a special hydrophobic carbon dot (HCD) to monitor biomolecular self-assembly along with the detection of metastable intermediates and self-aggregates. We exploited the restricted rotation of the S-S bond of the HCD synthesized from dithiosalicylic acid and melamine to exhibit different emission behaviors during the self-assembly of amino acids and proteins. The HCD that exhibits blue emission in amino acid droplets or protein aggregates dynamically changes its emission from blue to red with the time course of the amino acid self-assembly process. This unique and distinct change in emission can be visualized by the naked eye under a UV lamp. The ability of HCD to distinguish the biomolecular self-aggregated structures and monitor the self-assembly dynamics can be utilized for the visual detection of uncontrolled aggregation of proteins and peptides related to neurodegenerative diseases like Alzheimer’s and Parkinson’s disease.

Authors: Maslov Alexandr , Savielov Dmitry , Vakulenko Roman
Published: January 2025

To theoretically determine the law of motion of a vibrating plate with polymer concrete, the dynamic system "vibration plate - polymer concrete" was researched. The compacted polymer concrete in it is presented as a system with distributed parameters, which takes into account the action of elastic and dissipative resistance forces from polymer concrete at its surface compaction. In accordance with the accepted rheological model of polymer concrete, a partial derivative ratio between stress and deformation is proposed for conditions of a uniaxial stress state. A vibration wave equation describing the motion of the compacted polymer concrete was created. Its solution enables the determination of the law of propagation of elastic-viscous deformation waves in polymer concrete.

Authors: Pichugin Sergii
Published: January 2025

The article consistently examines the evolution of building construction calculation methods and their reflection in regulatory documents for the period from the 17th-18th centuries to the middle of the 20th century. Attention is drawn to the continuity of the method of limit states and the method of allowable stresses, which dominated the calculations of building structures until the 1950s. It is noted that foreign experience was taken into account when developing the first domestic design codes. A comparative analysis of the codes for calculating building structures based on allowable stresses with modern design codes is carried out. The general conclusion is substantiated that the method of allowable stresses, despite all its shortcomings, over the 200-year period of application still ensured the necessary reliability and safety of construction objects around the world. In the background of the method, a large and valuable baggage of scientific results was acquired, which were later laid as the basis of a new method of limit states

Published: January 2025

The paper explore the issue of cost-effectiveness of the transition from existing one-pipe, unregulated heating systems to two-pipe regulated apartment systems, with the possibility of installing thermostatic controls on each heater as well as heat meters in each apartment. Four residential buildings with the same specific heat load, which have central regulation, group regulation, local regulation and combined regulation, were selected. The actual heat consumption has been analysed and conclusions drawn as to the possible savings with combined control. One of the main conclusions is that renovation of existing in-house heating systems is an objective necessity

Authors: Orysenko Oleksandr , Skoryk Maksym , Kryvorot Anatolii , Virchenko Viktor
Published: January 2025

During the movement of a road train, the towing device takes on the load from one link of the road train and transmits it to another. In the study of the processes of links interaction in real traffic conditions, a spatial system of forces acts on each road train link and there is a need to bring them to the calculated plane. It is proposed to consider each link in a separate spatial coordinate system, which is fixed with this link, and then, using the developed transition tables, to bring these forces to the coordinate system, which is fixed with another link
Strength of fiber concrete (concrete) under local compression according to the theory of plasticity and experimental studies
Authors: Kuznietsova Iryna , Dovzhenko Oksana , Pohribnyi Volodymyr , Pants Volodymyr
Published: January 2025

Local compression of concrete is often implemented in supporting joints of reinforced concrete structures. As a strength calculation method for this case, a variational method in the theory of plasticity is proposed, which is based on the consideration of the failure stage and takes into account the full set of determining factors of strength: the dimensions of the sample, the shape and dimensions of the loading platform, its location, the ratio of the dimensions of the loading device and the element, type and class of concrete (by taking into account both strength characteristics). In experimental studies, the kinematic schemes of failure adopted in the calculation and the influence of determining factors were confirmed. A comparative analysis of the strength calculated by the proposed method with the experimental one for 78 samples showed that they are sufficiently close.

Published: January 2025

The characteristic geotechnical conditions of modern high-rise construction are considered. The engineering and geological conditions of the site were analyzed. In particular, it was noted that loose soils lie up to a depth of 2.2 m, and below 13.0…13.5 – eolian-deluvial deposits (sandy and silty loams with a deformation modulus of 5…7 MPa). The territory is flooded. An effec-tive constructive-technological solution was tested using the drilling-mixing method of placing soil-cement elements to strength-en the base made of highly compressible clay soils under the slab foundation of a multi-story residential building with a parking lot under the conditions of the existing building. The results of tests of soil cement samples, which were selected during the execution of works, for uniaxial compression are presented.

The results of parallel experimental studies of the physical and mechanical properties of sedimentary rocks of natural structure, including their penetration tests, are presented. The possibility of establishing empirical equations of the relationship between the physical (soil skeleton density and moisture content) and mechanical (specific resistance to penetration, angle of internal friction, specific adhesion, deformation modulus) characteristics of cohesive (on the example of light dusty loams of loess origin) and non-cohesive (on the example of fine sands, quartz) sedimentary rocks of natural structure is tested. It is noted that such equations are correct only for genetically identical types of sedimentary rocks

The development of practical aspects of environmental safety requires taking into account the necessary parameters of the tech-nical condition of equipment, namely oil pipelines, including their operating conditions, climatic features of the regions, stand-ardized risk and safety parameters, and residual resource based on reliability and durability indicators.
On the basis of the electrochemical corrosion mathematical pipeline model in the insulating coating crack under the action of an aggressive electrolytic medium towards the pipeline metal, the  dependence was obtained that allows  to calculate the  corrosion depth of the pipeline wall during the work of macro-galvanic corrosion couples in the conditions of stable and periodic stay of the aggressive solution in the damaged zone. The advantage of this model is the ability to predict the development of corrosion over time regardless of the corrosive electrolyte chemical composition, the possibility of obtaining necessary design parameters for operated structures. The developed dependencies of the pipeline section сorrosion depth make it possible to plan rationally the repair work, to predict the real terms of the structure work, to review the operation mode, etc. The obtained results allow us to more reliably evaluate the bearing capacity of structures that operate  in conditions of aggressive medium with cracks
Analysis of the calculation of support nodes bolted connections of cantilevered steel-reinforced concrete posts
Authors: Zakomirnyi Dmytro , Semko Oleksandr
Published: January 2025

In order to reduce steel consumption in the installation of support nodes of cantilevered pipe reinforced concrete advertising structures, the optimal ratio of the base plate size and the diameter of the support node anchor bolts of an existing advertising structure was calculated. The analysis of the calculations revealed the total cost dependence of the support node and anchor bolts on the overall node dimensions and the anchor bolts diameter. With an increase in the size of the support node, the cost of the support node metal increases much faster than the cost of the anchor bolts decreases. For more efficient use of materials, it is necessary to reduce the size of the node and increase the diameter of the anchor bolts accordingly. As a result of the research and calculations, the most efficient support node was determined. The savings in the total cost of such a node is 8.9% compared to the existing support node of the studied advertising structure
