Evaluation of Fused Deposition Modelling process parameters influence on the porosity of printed parts
Authors: Tumarchenko Larysa , Vyshnepolskyi Yevhen
Published: November 2024

Fused Deposition Modelling (FDM) is an additive manufacturing technology that is rapidly gaining popularity due to its ability to produce complex shaped parts in a short time. However, parts produced by means of FDM have porosity that results from the printing process. The mechanical properties of printed parts depend on the FDM process parameters and porosity. This study investigates the effect of FDM process parameters on the porosity of FDM parts. The results of the study show that properly selected FDM process parameters can significantly minimize the percentage of part porosity. The effect of FDM process parameters on porosity was determined by analyzing nine process variables: layer height, extrusion temperature, printing speed, extrusion multiplier, bed temperature, infill pattern, deposited strand width, number of shells, number of solid top and bottom layers. The percentage of samples porosity was measured by means of the hydrostatic weighing method. Using the analysis of variance, statistically significant factors and their combinations affecting the percentage of parts porosity were determined. It was shown that the extrusion multiplier had the greatest influence on the percentage of parts porosity. A significant contribution to the formation of porosity was made by the infill pattern, layer heights, printing speed, number of shells, number of solid top and bottom layers and their interaction. A regression model has been developed that allows predicting the porosity of parts achieved by different combinations of FDM process parameters.
Circuit quantization in Hamiltonian framework: a constraint analysis approach
Authors: Pandey Akshat , Ghosh Subir
Published: November 2024

In this work, we use Dirac’s constraint analysis (DCA) to solve superconducting quantum circuits (SQCs). The Lagrangian of an SQC reveals the constraints that are classified in a Hamiltonian framework, such that redundant variables can be removed to isolate the canonical degrees of freedom for subsequent quantization of the Dirac brackets. We demonstrate the robustness of DCA unlike certain other set of ideas like null vector and loop charge which are each applicable only to specific types of quantum circuits.

Las actividades de sacrificio de animales en un camal (matadero) requieren de gran consumo de agua; en consecuencia, generan aguas residuales con alta carga orgánica, cuya disposición representa un problema ambiental. Por esta razón, en la presente investigación se evaluó, mediante técnicas estadísticas, la eficiencia de los procesos Fenton y foto-Fenton para la remoción de materia orgánica del efluente del Camal Municipal de Cusco-Perú. Previamente se realizó la evaluación, el seguimiento y el análisis de las características del efluente y el diagnóstico del punto de muestreo. Para el muestreo del efluente se utilizaron la metodología y los procedimientos de toma de muestra establecidos por la normativa peruana. En cada uno de los experimentos realizados se determinaron las concentraciones inicial y final de la demanda bioquímica de oxígeno (DBO5). Se utilizó el diseño de caja Behnken para la matriz de distribución de los 30 experimentos con sus respectivos niveles, correspondiente a los parámetros FeSO4•7H2O, H2O2 y pH. Los ensayos se realizaron en una prueba de jarras, con velocidad de agitación de 150 rpm y tiempo de reacción de 1 h. En el caso del proceso foto-Fenton, se instaló un foto-reactor con una lámpara 13 W (UV-C 254 nm), empleando la misma velocidad de agitación y tiempo de reacción. Respecto del proceso Fenton, los resultados alcanzados en la investigación indican un decaimiento de la DBO5 del 93.96 %, en comparación con el proceso foto-Fenton, que alcanzó un 94.63 %.
An Analysis of Three Episodes in My Life from the Sociolinguistics PerspectiveAn Analysis of Three Episodes in My Life from the Sociolinguistics Perspective
Authors: Van An
Published: November 2024

In sociolinguistics, considering language from the perspective of race has a long history (Grieser, 2021). From this perspective, one of the challenges that language teachers from diverse backgrounds face is the racialization of their language. This refers to the tendency to be judged based on race, ethnicity, and accents rather than linguistic abilities. This can lead to stereotypes, prejudice, and discrimination towards English teachers who speak differently from the perceived ‘standard’ English. Moreover, the dichotomy between standard and non-standard English is also controversial in this context. The concept of standard English has been a topic of debate for many years, with different perspectives and arguments. On the one hand, some scholars argue that unmarked standard English spoken by a certain group of white, privileged, and affluent people should be taught. On the other hand, others argue that there is no such thing as standard English and that students should be exposed to the different varieties of English spoken worldwide, known as World Englishes. Promoting linguistic and cultural diversity and recognizing the value of non-standard varieties of English is considered necessary by some sociolinguists.
This paper aims to explore the issue of racialization that language teachers from diverse backgrounds face and to answer the questions : (1) Is there a standard English that should be taught and (2) Should students be exposed to World Englishes? The paper will examine the various perspectives and arguments surrounding this issue, drawing on sociolinguistic research and theory and three episodes in my life to comprehensively understand the topic and its implications for sociolinguistics.

A Bivariate Extension of Type II Generalized Crack Distribution for Modelling Heavy-Tailed Losses
Authors: Bae Taehan , Quarshie Hanson
Published: November 2024

As an extension of the (univariate) Birnbaum-Saunders distribution, the Type II generalized crack (GCR2) distribution, built on an appropriate base density, provides a sufficient level of flexibility to fit various distributional shapes including heavy-tailed ones. In this paper, we develop a bivariate extension of the Type-II generalized crack distribution and study its dependency structure. For practical applications, several specific distributions, GCR2-Generalized Gaussian, GCR2-Student’s t and GCR2-Logistic, are constructed. The expectation-maximization algorithm is implemented to estimate the parameters in the bivariate GCR2 models. The model fitting results on the catastrophic loss dataset show that the bivariate GCR2 distribution base on the generalized Gaussian density fits the data significantly better than other alternative models.
On Defining Expressions for Entropy and Cross-Entropy: The Entropic Transreals and Its Fracterm Calculus
Authors: Bergstra Jan A , Tucker John V
Published: November 2024

Classic formulae for entropy and cross entropy contain operations 0x and log2 x that are 1 not defined on all inputs. This can lead to calculations with problematic subexpressions such as 2 0 log2 0 and uncertainties in large scale calculations; partiality also introduces complications in logical 3 analysis. Instead of adding conventions, or splitting formulae into cases, we create a new algebra 4 of real numbers with two symbols ±∞, for signed infinite values, and a symbol named ⊥ for the 5 undefined. In this resulting arithmetic, entropy, cross-entropy, Kullback-Leibler divergence, and 6 Shannon divergence can be expressed without any further conventions concerning. The algebra may 7 form a basis for probability theory more generally.

Published: November 2024

Background/Objectives: Recent advancements in artificial intelligence (AI) have spurred interest in developing computer-assisted analysis for imaging examinations. However, the lack of high-quality datasets remains a significant bottleneck. Labeling instructions are critical to improving dataset quality but are often lacking. This study aimed to establish a liver MRI segmentation protocol and assess its impact on annotation quality and inter-reader agreement; Methods: This retrospective study included 20 patients with chronic liver disease. Manual liver segmentations were performed by a radiologist in training and a radiology technician on T2 weighted imaging (wi) and T1wi at the portal venous phase. Based on the inter-reader discrepancies identified after the first segmentation round, a segmentation protocol was established, guiding the second round of segmentation, resulting in a total of 160 segmentations. Dice Similarity Coefficient (DSC) assessed inter-reader agreement pre- and post-protocol with a Wilcoxon signed-rank test. Slice selection at extreme cranial or caudal liver positions was evaluated using the McNemar test; Results: The per-volume DSC significantly increased after protocol implementation for both T2wi (p<0.001) and T1wi (p=0.03). Per-slice DSC also improved significantly for both T2wi and T1wi (p<0.001). The protocol reduced the number of liver segmentations with a non-annotated slice on T1wi (p=0.04), but the change was not significant on T2wi (p=0.16); Conclusions: Establishing a liver MRI segmentation protocol improves annotation robustness and reproducibility, paving the way for advanced computer-assisted analysis. Moreover, segmentation protocols could be extended to other organs and lesions and incorporated into guidelines, thereby expanding the potential applications of AI in daily clinical practice.

Published: November 2024

Cervical cancer remains a significant global public health challenge, affecting over half a million women annually, with a mortality rate of approximately 60%, especially in resource-limited regions. This study presents an advanced methodology for cervical cancer diagnosis through deep learning techniques. Utilizing a publicly available cervical cancer image dataset, the research introduces a novel classification framework that integrates a Neural Feature Extractor (NFE) based on a pre-trained VGG16 architecture and an AutoInt model for automatic feature interaction learning. The extracted features are processed through machine learning classifiers such as KNN, LGBM, Extra Trees, and others for classification tasks. Among these classifiers, KNN achieved the highest accuracy of 99.96%, followed closely by LGBM at 99.92%. The study also assesses the computational complexity of various models, demonstrating that simpler models like LDA exhibit faster prediction times, while more complex models, such as KNN and LGBM, provide higher accuracy. These findings highlight the potential of deep learning frameworks in improving cervical cancer classification accuracy, especially in resource-limited environments.

Accurate information on ecotourism site suitability is crucial for effective planning, aiding in ecological conservation and local economic uplift. This study addresses the lack of documented ecotourism site suitability in the Lake Tana watershed of Ethiopia by evaluating factors such as elevation, slope, vegetation density, and proximity to water and infrastructure using Geographical Information System (GIS) and multi-criteria evaluation methods. The Analytical Hierarchy Process (AHP) combined with GIS was used to create a resource inventory and establish sustainable tourism criteria. A suitability map was developed based on weights from pair-wise comparisons of the selected criteria. Results show that 20% of the area, particularly near Lake Tana and water bodies, is highly suitable for ecotourism. Additionally, 50% is moderately suitable, 3.1% is marginally suitable, and 26% is unsuitable for development. These findings can guide resilient policies for ecotourism initiatives and help assess sustainable tourism in other regions. Regional tourism offices, Non-governmental Organizations, and policymakers can use this data to evaluate natural resource suitability for ecotourism, providing a foundation for further research in the field.

Authors: Vargas-Chaves Iván , Cumbe-Figueroa Alexandra , Marulanda Diana
Published: November 2024

This paper studies the Constitutional Court of Colombia decision T-1077/2012, one of the most important precedents of constitutional protection of the Right to health through the precautionary principle. The objective proposed by the authors is to study the conditions of invocability of the precautionary principle that were considered in the sentence. Based on the precedent of this case, the Court created a line of interpretation that transcended to other fields, by extending its application in a reinforced manner. The methodology used was a systematic review, through a meta-analysis of the case decision, as well as a documentary analysis of the specialized literature. The paper concludes that this case became a reference for the future application of the precautionary principle in public health. The Court moves away from the classical conception of the principle to prevent strictly environmental risks, reformulating its constitutional protection to the field of the right to health, in a context of scientific uncertainty.

This paper presents the results of constructing a model of the geoelectric structure of Northern Vietnam obtained by 3D inversion of magnetovariational tippers calculated for 13 values of variation periods in a range of 40–10047 s at 12 points where geomagnetic variations are recorded. Inversion is performed using the ModEM software, which makes it possible to construct a model in a 400 × 400 × 200-km spatial region with the center at the Hanoi Observatory (PHU). The resulting model of the geoelectric structure contains two regional blocks separated by the Red River fault region. A conductive block is located in the southwest of the fault region, and a high-resistivity block is located in the northeast. The boundary of the blocks, inclined to the northeast at an angle of about 45°, is visible to a depth of 150 km. The conductive block occupies the region between the Red River and Song Ma faults. Its western boundary could not be localized due to insufficient data in this region. Highly conductive local blocks stand out against the background of the regional conductive block. They usually gravitate toward the faults and are located in a depth range of 10–20 km with a slight inclination to the west on latitudinal profiles and to the south on meridional ones. In a depth range of 12–14 km, they merge into one highly conductive band extending in the northwest and marking the Red River fault system connected to the Gulf of Tonkin waters. Also, there are more massive highly conductive blocks in depth intervals of 20–50 km, which are often associated with upper crustal ones. There is a highly conductive block observed on the latitudinal profile, passing through the central region of the Hanoi Basin, and steeply dipping to the east (75°) to depths of more than 100 km. The deep geoelectric features of the Red River fault system are compared with the geoelectric section under their continuation in Southern Tibet in the adjacent territory in China.

The formation mechanisms of sedimentary basins are considered as a response of deep processes in the mantle, therefore they carry important information about the geodynamics and thermal regime of the lithosphere. For different sectors of the northern margin of the Siberian Platform, the dynamics of sedimentation and subsidence was reconstructed. The analysis of subsidence curves shows that during the late Paleozoic the sedimentary infill formed in the foreland basin environment. In the Late Permian–Early Triassic time, in the central and western sectors, the subsidence was accelerating due to the development of a thick trap complex; after the Permian and Triassic boundary the subsidence slowed down. During the period of trap magmatism, an anomalously high subsidence rate up to 4.8 km/ Myr in the central and up to 0.5–1.1 km/ Myr in the eastern and western parts was reconstructed. The high rate and short duration of accumulation of volcanogenic sediments can be explained by an episode of short-term extension under the influence of a plume, followed by a long period of thermal subsidence. Numerical modelling of the temperature regime near mafic intrusive bodies was carried out, which showed that when determining the paleoheat flow, the influence of trap intrusions can be traced up to 400–500 m from the contacts. Estimates of the paleoheat flow for the Permian–Triassic stage of tectonic evolution of the eastern sector were obtained. It was calibrated using the PetroMod software package, based on laboratory measurements of modern values of vitrinite reflectance for rock samples from wells, modern temperature and heat flow in the sedimentary cover. It was determined that trap magmatism occurred at temperatures increased to 100 mW/m2, while the mantle component of the heat flow reached 38–72 mW/m2; it is several times higher as compared to modern one. The obtained paleoheat flow estimates for the Late Permian–Early Triassic stage appear to correspond to anomalously high values of modern continental rifts.

Reflexo de fatores socioambientais e políticos, como o aumento da urbanização, o excesso de consumismo, crescimento populacional, a inadequada utilização da água, há um quadro geral de grave crise hídrica. Percebeu-se a importância e a finitude da qualidade desse bem e a necessidade de se reavaliar e fortalecer sua tutela no contexto brasileiro. O presente artigo objetivou a análise dos principais aspectos da regulamentação da água no ordenamento jurídico brasileiro, no sentido de se repensar a tutela jurídica para governança da água. A Constituição Federal de 1988 inaugurou a proteção à água de forma indireta e foi um marco de evolução considerável, estabelecendo que as águas são bens de domínio público, trazendo um tratamento a partir de bacias hidrográficas. Os normativos preveem a sustentabilidade e o uso racional da água, e gestão descentralizada que envolve o poder público e a sociedade. Porém, há limitações técnicas e axiológicas na política hídrica que implicam em uma gestão, muitas vezes, engessada. Verifica-se pouca melhoria na crise e situação de risco. A metodologia utilizada foi o método dedutivo, com abordagem qualitativa de pesquisa bibliográfica. Conclui-se que novas abordagens e inovações jurídicas trazem a reflexão para a reformulação da governança da água, com mudanças de enfoques, paradigmas e metodologias, e que o reconhecimento da água como direito fundamental pode ser relevante nesse progresso, bem como, a consideração dos direitos supra-humanos.  Portanto, são necessários processos interligados a partir de conhecimentos interdisciplinares na gestão pública da água.
Probabilities of reaching required diffusion of granular energy technologies in European countries

To support discussions around the feasibility of the energy transition, we present probabilistic projections of the expected baseline diffusion of solar photovoltaics, wind power, biogases, heat pumps and low-carbon passenger vehicles in 39 European countries for 2023-2050 under current contextual conditions. We then compare the projected capacities against those required for reaching net-zero greenhouse gas emissions by 2050. We create our projections using 72 different variants of diffusion models that we validate using hindcasting (2012-2022) and weigh according to their performance. We find a notable expected growth in solar photovoltaics, heat pumps, and battery electric vehicles in the majority of European countries. However, most countries are unlikely to reach the required capacities for net-zero emissions of wind power and biogases with high confidence, and battery electric vehicles with lower confidence. Probabilities and confidence levels of reaching required capacities of solar photovoltaics and heat pumps vary the most between countries.

Precise Nanochemistry of Spherical Aluminum Oxo Clusters for Accurate Surface Guest Recognition and Release

Published: November 2024

Research on the adsorption of nanoparticles faces significant challenges due to their small size, which leads to ambiguous structures and renders traditional analytical methods inadequate for providing clear information. Nanoclusters, however, offer a promising solution to this issue, as their precise structural information and controllable features enable scientists to investigate surface adsorption phenomena and their behavior under various environmental conditions more effectively. In this study, we present a novel "co-encapsulation" synthetic strategy that successfully synthesizes the first spherical aluminum oxo cluster (SAlOC-1). This innovative approach draws inspiration from hydrophobic surfactant molecules found in spherical micelles and thus we select flexible, sterically hindered probenecid ligands as chelating ligands. The distinctive spherical structure of SAlOC-1 maximizes exposure of the surface binding sites, creating an optimal environment for guest inclusion. Notably, SAlOC-1 demonstrates a single crystal to single crystal transformation at room temperature, showcasing its remarkable capacity to accommodate up to 14 different drug-related guests across a broad volume range. These findings illustrate the unique advantages of SAlOC-1 in guest determination, including the ability to overcome limitations associated with liquid-phase host-guest chemistry in traditional discrete systems, ease of operation, and the coexistence of universality and selectivity. The implications of this work extend across numerous fields, including drug delivery, catalysis, and beyond.

We studied post-pandemic T-cell responses to five distantly related sarbecoviruses, possessing human ACE2 binding properties (SAR-CoV-1 and 2, pangolin coronavirus GX-P4L, and bat coronaviruses RSYN04 and Khosta2), and MERS-CoV. We used peripheral blood mononuclear cells samples collected before and after vaccination from health care workers in the UK and Vietnam. Strong T-cell responses to all the tested sarbecoviruses were observed in samples collected post vaccination only, with a mixture of CD4+ and CD8+ T-cells responses. There was a strong correlation between the level of T-cell responses and the degree of sequence homology. Very limited cross reactivity was observed for MERS-CoV. Collectively, we showed that post-pandemic T-cell responses cross-recognise human ACE2-dependent sarbecoviruses. The data thus suggest there may be partial protection from the post-pandemic T-cell response landscape against sarbecoviruses that have the potential to cause spillover. Our findings should be used to inform the developments and deployment of countermeasures against sarbecoviruses.
