Published: October 2024

This study aims to develop a PM2.5 concentration prediction model using ensemble learning techniques, focusing on the application of stacking regressor. The developed model is compared with several other basic models, namely LSTM, Random Forest, XGBoost, and GBM, to evaluate its performance in terms of prediction accuracy. The results show that the stacking regressor model provides more accurate prediction results than these basic models. The LSTM model has a Mean Squared Error (MSE) value of 80.42 and a coefficient of determination (R²) of -0.29, which shows unsatisfactory performance despite being able to capture temporal patterns. Random Forest gave better results with an MSE of 10.90 and R² of 0.83, thanks to its ability to handle heterogeneous data. The XGBoost and GBM models showed similar performance, with MSE of 9.01 and 8.81 respectively and R² of 0.86. However, the stacking regressor model with the RidgeCV meta-learner achieved the best results with an MSE of 8.07 and R² of 0.87, indicating that this technique successfully combines the advantages of various base models to improve prediction accuracy. In conclusion, the stacking regressor model proved effective in improving PM2.5 prediction accuracy, making it a potential tool for air quality monitoring and supporting public health policy making. This research makes an important contribution to the development of ensemble learning-based air quality prediction methods, and the results can serve as a reference for future research

Published: October 2024

Increasing vehicle density in Guayaquil has raised concerns about its impact on the quality of road infrastructure, particularly on the wear and tear of asphalt pavement. This study aims to assess the relationship between vehicular traffic and pavement deterioration in the city, focusing on several areas with different levels of density. Counting cameras and traffic sensors were used to record the volume of vehicles, categorising them into light and heavy, as well as visual inspections to measure pavement wear. The results revealed that areas with high vehicle density had a higher degree of pavement deterioration, with a significant increase in cracking and cracking. The data show that heavy traffic is a major contributor to accelerated road wear, which in turn can impact road safety and public health by releasing more pollutants into the air.
Impact of asphalt pavement wear-based business development on air pollution in the city of Guayaquil
Authors: Guadalupe Méndez Glenda Lorena , Vargas Jiménez Julio Alberto , Pacheco Quintana Guillermo Alexander , Vargas Guadalupe Julio Andrés
Published: October 2024

The wear and tear of the asphalt pavement, caused by constant vehicular traffic, represents a relevant factor in air pollution in the city of Guayaquil. This phenomenon is especially worrying in areas of high vehicle density, where constant friction and the passage of heavy vehicles accelerate the deterioration of the asphalt. As the pavement wears down, polluting particles such as PM10 and PM2.5 are generated and released into the air, posing a considerable risk to public health. These particles, when inhaled, can penetrate deep into the lungs, causing respiratory and cardiovascular diseases.

Published: October 2024

Aim: The purpose of our study was to highlight CTS, which is generally overlooked by physicians in pregnant, resulting in inadequate diagnosis and treatment, and to investigate the related risk factors in pregnant who are diagnosed with CTS. Materials and Methods: In our study, the demographic, clinical, and laboratory data of 82 pregnant, who were diagnosed with CTS, who were in the 3rd trimester, and whose pregnancy follow-ups were performed by us between March 2018-2023, and 82 pregnant in the control group were assessed retrospectively. Results: BMI values were observed to be significantly greater in the group with CTS compared to the group without CTS(p:0.036). The HbA1c level was 5.4±0.2 in the group with CTS, and 5.1±0.3 in the group without CTS, and it was significantly higher in the group with CTS(p:0.038).The TSH level was 2.9±0.6(mIU/L) in the group with CTS, and 2.4±0.5(mIU/L) in the group without CTS, and it was significantly greater in the group with CTS(p:0.042). A positive, statistically significant, and moderate correlation was detected between the CTS-6 value and BMI score (p:0.006, r=0.438). Another statistically significant, positive, and weak correlation was detected between the CTS-6 score and HbA1c level(p:0.028, r=0.234). Conclusion: It is especially important to pay attention to many risk factors because subclinical CTS during pregnancy can lead to permanent complications. We think the present study's findings are important for healthcare providers and will contribute significantly to the understanding of the relationship between CTS and pregnancy by shedding light on the relationship between relevant variables and the prevalence of CTS.

Aim: Our hypothesis was that lubricating gels used at the beginning of the active phase of labor could reduce the incidence of episiotomies and shorten the duration of labor. This study aims to investigate and confirm this theory with a randomized controlled trial.
Material and Methods: A prospective randomized controlled trial was conducted at obstetrics and gynecology department of a university hospital between January 2017 and April 2017. The study included 102 nulliparous and 93 primiparous singleton pregnancies. 50 primiparous women and 47 nulliparous patients were randomly assigned to the obstetric gel group. Obstetric gel was applied to participants in the study groups at the beginning of the active phase of labor. Outcomes were episiotomy rates and duration of labor.
Results: Episiotomy rates were significantly lower in nulliparous obstetric gel group (36.1% and 63.6%, p=0.005). The duration of the active phase of the first and second stage of labor was significantly lower in the obstetrical gel groups compared to the control groups in both parities (150 ± 86 and 203. 5 ± 134, p=0.021, 28.8 ± 18.2 and 62.6 ± 53.8, p
Convolution Algebras of Double Groupoids and Strict 2-Groups
Authors:   Washington University in St. Louis, USA, Román Angel , Villatoro Joel ,   Indiana University Bloomington, USA
Published: October 2024

Double groupoids are a type of higher groupoid structure that can arise when one has two distinct groupoid products on the same set of arrows. A particularly important example of such structures is the irrational torus and, more generally, strict 2-groups. Groupoid structures give rise to convolution operations on the space of arrows. Therefore, a double groupoid comes equipped with two product operations on the space of functions. In this article we investigate in what sense these two convolution operations are compatible. We use the representation theory of compact Lie groups to get insight into a certain class of 2-groups.

Sub-Neptune planets with radii smaller than Neptune (3.9 R
⊕) are the most common type of planet known to exist in the Milky Way, even though they are absent in the solar system. These planets can potentially have a large diversity of compositions as a result of different mixtures of rocky material, icy material, and gas accreted from a protoplanetary disk. However, the bulk density of a sub-Neptune, informed by its mass and radius alone, cannot uniquely constrain its composition; atmospheric spectroscopy is necessary. GJ 1214 b, which hosts an atmosphere that is potentially the most favorable for spectroscopic detection of any sub-Neptune, is instead enshrouded in aerosols (thus showing no spectroscopic features), hiding its composition from view at previously observed wavelengths in its terminator. Here, we present a JWST NIRSpec transmission spectrum from 2.8 to 5.1 μm that shows signatures of CO2 and CH4, expected at high metallicity. A model containing both these molecules is preferred by 3.3σ and 3.6σ as compared to a featureless spectrum for two different data analysis pipelines, respectively. Given the low signal-to-noise of the features compared to the continuum, however, more observations are needed to confirm the CO2 and CH4 signatures and better constrain other diagnostic features in the near-infrared. Further modeling of the planet’s atmosphere, interior structure and origins will provide valuable insights about how sub-Neptunes like GJ 1214 b form and evolve.
A holistic physics-informed neural network solution for precise destruction of breast tumors using focused ultrasound on a realistic breast model
Authors: Lari Salman , Rajabzadeh Hossein , Kohandel Mohammad , Kwon Hyock Ju
Published: October 2024

This study presented a novel approach for the precise ablation of breast tumors using focused ultrasound (FUS), leveraging a physics-informed neural network (PINN) integrated with a realistic breast model. FUS has shown significant promise in treating breast tumors by effectively targeting and ablating cancerous tissue. This technique employs concentrated ultrasonic waves to generate intense heat, effectively destroying cancerous tissue. In previous finite element method (FEM) models, the computational demands of handling extensive datasets, multiple dimensions, and discretization posed significant challenges. Our PINN-based solution operated efficiently in a mesh-free domain, achieving remarkable accuracy with significantly reduced computational demands, compared to conventional FEM techniques. Additionally, employing PINN for estimating partial differential equations (PDE) solutions can notably decrease the enormous number of discretized elements needed. The model employed a bowl-shaped acoustic transducer to focus ultrasound waves accurately on the tumor location. The simulation results offered detailed insights into each step of the FUS treatment process, including the generation of acoustic waves, the targeting of the tumor, and the subsequent heating and ablation of cancerous tissue. By applying a 3.8 nm displacement amplitude of transducer input pulse at a frequency of 1.1 MHz for 1 second, the temperature at the focal point elevated to 38.4 ℃, followed by another 90 seconds of cooling time, which resulted in significant necrosis of the tumor tissues. Validation of the PINN model's accuracy was conducted through FEM analysis, aligning closely with real-world FUS therapy scenarios. This innovative model provided physicians with a predictive tool to estimate the necrosis of tumor tissue, facilitating the customization of FUS treatment strategies for individual breast cancer patients.

A partir de uno o varios libros de poesía publicados, tratar de mostrar cómo se construye el archivo (tanto en su materialidad como en función de un «proyecto» abierto a una dinámica de producción), cómo una obra, o una serie de obras o proyectos, reelaboran ese material, dialogan con él, y ponen a dialogar ese archivo con los de la Historia. El cuerpo como hilo conductor: el «desplazamiento» de lo corpóreo, de las figuraciones y usos del cuerpo, correspondiéndose con fundamentos de la construcción de ese archivo. ¿Cómo una experiencia me lleva a una escritura y antes viene de una lectura o va hacia una lectura con la que coincide a posteriori?

Les Indo-Européens, des ancêtres encombrants ?
Authors: Demoule Jean-Paul
Published: October 2024

La reconnaissance d’une parenté entre les langues de la plupart des régions de l’Europe et d’une partie de l’Asie occidentale s’est peu à peu imposée et a donc défini la famille des langues dites indo-européennes, plus proches les unes des autres qu’elles ne le sont d’autres familles de langues, sémitiques, sino-tibétaines ou autres. L’interprétation de cette parenté indiscutable s’est inspirée du cas des langues romanes, toutes plus ou moins descendantes du latin à la suite de la conquête romaine d’une partie de l’Europe. On a donc cherché d’où aurait pu partir ce peuple préhistorique conquérant, dont la langue originelle reconstruite aurait donné naissance à toutes celles d’aujourd’hui. Parmi d’innombrables hypothèses, trois surnagent. La première est le pourtour de la Baltique ; sans aucun argument archéologique, elle a été soutenue en son temps par le nazisme et reprise par certaines extrêmes droites actuelles. La deuxième est le Proche-Orient et s’identifierait avec la diffusion de l’agriculture sédentaire (le néolithique) à partir de cette région. La troisième, actuellement majoritaire, verrait des guerriers cavaliers issus des steppes de la mer Noire se répandre ensuite dans toute l’Europe et aux alentours. Malgré le secours récent, popularisé à grand bruit, de la génétique, cette dernière ne saurait se réduire aux formes simplistes qu’on lui a données. C’est pourquoi ce sont des modèles beaucoup plus complexes, aussi bien sur le plan linguistique (au-delà d’un simple arbre généalogique) que sur le plan historique et anthropologique (au-delà d’un modèle invasionniste et colonial), quant à la formation et à la diffusion de ces langues, qui mériteraient d’être désormais développés.

Trente ans après l’épisode final de la guerre civile et du génocide des Rwandais tutsis, le Mécanisme international appelé depuis 2010 à exercer les fonctions résiduelles des tribunaux pénaux pour le Rwanda et l’ex-Yougoslavie a clôturé pour l’essentiel les procédures relatives aux ultimes dossiers d’accusés poursuivis par le Tribunal pénal international pour le Rwanda. Cet article propose un bilan succinct de son activité et des débats que suscite le transfert de ses archives aux autorités nationales lors de sa fermeture prochaine.
La reconnaissance du génocide des Arméniens : un itinéraire politique inachevé
Authors: Marian Michel
Published: October 2024

La mise en mémoire du génocide des Arméniens a connu, globalement et en France, un cheminement générationnel et psychologique commun à celui des grands traumatismes collectifs. La reconstruction des personnes et la réception du récit collectif ont pourtant suivi une voie particulière. Le combat mené par le régime républicain de la Turquie contre la résurgence de cette mémoire a produit une scène mémorielle à trois acteurs ( plaignant, accusé et juge), distincte du modèle du travail intérieur sur la Shoah ou de l’interpellation postcoloniale. Mais, du fait du refus et de l’éloignement, il ne pouvait se construire un droit positif de ce crime. Le besoin d’une solution a fait apparaître un « droit à la mémoire », où la vérité est due aux victimes, à défaut d’une justice. C’est cette logique, formulée en France dès les années 1980, qui s’est développée jusqu’à 2019 et la décision française d’une journée annuelle de commémoration du génocide des Arméniens ou 2021 et la reconnaissance du génocide par Joe Biden. Elle a aussi facilité pour les Arméniens de France la construction d’une communauté loyale à la République et fidèle à son histoire. Elle est pourtant insuffisante devant une négation qui persiste, bloque le devenir démocratique de la Turquie, se propage de celle-ci à l’Azerbaïdjan et tend les relations entre ces pays et ceux qui ont accueilli la diaspora arménienne.
Quand la mémoire est une arme de guerre identitaire
Authors: Meyran Régis
Published: October 2024

La mémoire est aujourd’hui instrumentalisée par l’extrême droite, y compris quand il s’agit de la mémoire de la Shoah, ce qui est nouveau et paradoxal, en même temps que par des groupes identitaires se revendiquant d’extrême gauche mais dérivant vers l’extrême droite. Au même moment, l’État défend une mémoire patrimoniale qui flirte avec le nationalisme. Parallèlement, il néglige les mémoires de l’esclavage et de la colonisation, mais aussi les mémoires ouvrières et populaires, ce qui engendre de nombreuses tensions dans la société civile. Cette situation favorise la guerre des mémoires et la montée d’identités fermées, qui menacent potentiellement la démocratie.
The diagnostic and prognostic significance of L1 cell adhesion molecule, Sperm-associated antigen 9 and P53 expression in endometrial lesions (immunohistochemical study)
Authors: Elshawarby Zeinab I. , Saad Eman A. , Eleleimy Hiam A. , Aboelkheir Mona A.
Published: October 2024

Background

Endometrial carcinoma is the most common invasive neoplasm of the female reproductive tract. L1 cell adhesion molecule (L1CAM), Sperm-associated antigen 9 (SPAG9), and P53 have a role in the process of tumorigenesis and progression of several human malignant tumors, however, the role of them in cancer of endometrium is still not clear.

Aim

The study was performed to evaluate L1CAM, SPAG9, and P53 expression about different clinicopathological parameters in endometrial endometrioid adenocarcinoma.

Methods

The immunohistochemical study was performed on 50 cases of endometrial lesions including endometrial hyperplasia without atypia (10 cases), endometrial hyperplasia with atypia (10 cases), and endometrial endometrioid carcinoma (30 cases). Immunohistochemical staining techniques were used to evaluate the role of L1CAM, P53, and SPAG9 in endometrial endometrioid adenocarcinoma (EEC) and their relation to different clinicopathological data and patient’s survival followed for 36 months.

Results

This study declared that both L1CAM and SPAG9 were found to be upregulated in EEC. Their over-expression was related to adverse clinicopathological parameters including high tumor grade, deep myometrial invasion, lymphovascular Invasion (LVI), and advanced tumor stage, while there was no significant relation between their expression and tumor size, cervical affection, and lymph node involvement. A high statistically significant link between L1CAM expression and poor patient survival was detected. Mutant type P53 was significantly related to adverse clinicopathological data as high tumor grade, deep myometrial invasion, lymphovascular space invasion (LVSI), and high tumor stage. There was a positive significant relation between mutant type P53 and high SPAG9.

Conclusions

The early identification of EEC in asymptomatic high-risk women may benefit from L1CAM and SPAG9 testing in combination with P53 protein. Also, they could be viewed as separate predictive variables in the EEC and might play a crucial part in the EEC’s chemoresistance.

Published: October 2024

Background

Colorectal cancer (CRC) has emerged as a significant health issue affecting millions worldwide. The current study aimed to evaluate circulating H19 expression levels as a noninvasive CRC biomarker and its relationship to tissue expression of β catenin as one of the most oncogenic pathways involved in CRC.

Patients and methods

Thirty patients were enrolled in the current study, all diagnosed with operable CRC. Another group of 30 healthy age-matched and sex-matched individuals were enrolled in this study as a control group. H19 expression levels were measured in plasma samples from 30 CRC patients before and 14 days after surgery and in 30 plasma samples from healthy controls using quantitative real-time PCR. In addition, tissue expression of β catenin was determined using the immunohistochemistry technique.

Results

Preoperative H19 expression in plasma was signfcantly upregulated in comparison to controls and a significant decline occurred postoperatively. All CRC cases showed positive β catenin expression. Furthermore, H19 correlated positively with β catenin score. Receiver-operator curve analysis revealed the high diagnostic significance of plasma H19 to discriminate CRC patients from control, which improved when combined with serum carcinoembryonic antigen and carbohydrate antigen 19-9. Moreover, H19 expression correlated positively with tumor-node-metastasis staging of the disease.

Conclusions

Our findings suggest the oncogenic role of H19 in CRC and identify its expression level in plasma as a promising biomarker that could be very helpful in early diagnosis of CRC and could also help in CRC prognosis.

Authors: Kumar Sunil , Bhattacharyya Debajyoti , Singh Bijender , Khanna Puneet , Qureshi Mohd Ishaque
Published: October 2024

Background:

Despite extensive research, pathophysiology of delirium remains inadequately understood, with studies suggesting a role for inflammatory mediators, cholinergic deficiency, and metabolic disturbances.

Aim:

This study aims to explore the association of electrolytes and other metabolic parameters in hospitalized delirium patients as compared to age- and gender-matched nondelirious controls.

Materials and Methods:

The observational case–control study was conducted at a multispecialty hospital in eastern India where 100 inpatients diagnosed with delirium (cases) and an equal number of age- and gender-matched nondelirious inpatients (controls) were administered a semi-structured pro forma for sociodemographic variables and assessed for electrolytes and other metabolic parameters. Statistical analysis employed Pearson’s Chi-square test to assess the significance of differences between the two groups.

Results:

The study revealed statistically significant differences in metabolic disturbances in delirium cases as compared to controls with a greater association of hyperglycemia (P = 0.009), hyponatremia (P = 0.002), hypercalcemia (P = 0.001), hyperkalemia (P = 0.030), and hypokalemia (P = 0.005) among delirium patients. Hypoalbuminemia (P = 0.002) and elevated bilirubin levels (P = 0.014) as well as uremia (P < 0.001) and elevated creatinine levels (P < 0.001) also had a greater association with delirium cases than controls. Sociodemographic analysis revealed a higher incidence of delirium in older adults and males.

Conclusion:

There was a significant association between delirium and various biochemical disturbances, highlighting the importance of thorough metabolic workup to identify and correct these disturbances which would potentially enhance delirium outcomes. There is a need for further studies to explore the causal pathways of these associations and the impact of targeted metabolic interventions on delirium outcomes.
Bending Analysis of Multiwall Carbon Nanotube Reinforced Functionally Graded Composite Cylindrical Shell

Published: October 2024

The curved structural components of aircraft, automobiles, and marine vessels, such as cylindrical panels, are primarily exposed to loading, which can result in bending failure, particularly in lightweight structures. The bending analysis of cylindrical panels made of functionally graded multiwall carbon nanotube (FG-MWCNT) epoxy composites is subjective in this study. In the first section, FG-MWCNT composite cylindrical panels are simulated in the ANSYS software. There are three methods for distributing uniaxially aligned reinforcements. The material properties of the carbon nanotubes uniformly distributed and functionally graded over the thickness of the shell structure are estimated using an extended rule of mixture micromechanical model that incorporates certain useful characteristics. To demonstrate the effectiveness and applicability of the proposed finite element approach, deflection data are presented. The analysis of the shell structure's bending includes an investigation of the impact of CNT volume fraction, boundary condition, lengthto-thickness ratio, and other geometrical factors
Computational Fluid Dynamics Analysis on Proton Exchange Membrane (PEM) Fuel Cell Performance using Honeycomb Flow Channel

Published: October 2024

Proton exchange membrane fuel cell (PEMFC) systems have the ability to meet our energy demands in the near future since they are green, economical, and clean. They can also use hydrogen as a direct fuel. One of the key design factors influencing the PEMFC's performance is flow field configuration. The configuration of the flow channel in a PEMFC has a profound effect on reactant distribution and water management within the fuel cell. Current study aims to ameliorate fuel cell (FC) performance, water management, and pressure drop (PD) across channels. ANSYS Fluent 18.2 software, including its PEMFC add-on module, is utilized to execute a computational fluid dynamics (CFD) simulation of a 3D model of a PEMFC with a flow channel shaped like a honeycomb structure. A polarization curve, as well as factors such as PD, hydrogen and oxygen concentrations, membrane water content, and current density distribution along flow channels, have been included in the simulation results. The findings suggest that when the FC is operated at 0.45V, homogeneous reactant consumption and greater power and current densities are achieved, and, water generation is high across the Membrane Electrode Assembly (MEA).
