Authors: Климова Екатерина Викторовна , Фролова Анастасия Максимовна
Published: December 2024

В статье представлены результаты исследования эффективности перевозки массовых грузов в различных типах подвижного состава. Установлено, что получила применение технология перевозок угольных грузов на экспорт в контейнерах с открывающейся крышей Open Top. Не смотря на ряд преимуществ у такой технологии есть и недостатки, которые являются существенными для направлений с дефицитом пропускной и провозной способности. Выбор типа подвижного состава должен основываться на ряде ограничений, таких как норма массы и длины состава и может выполняться по натуральным или стоимостным критериям в зависимости от стороны выгодоприобретателя - перевозчика или клиента. В исследовании представлена методика, позволяющая достигнуть максимизации или минимизации значения выбранного критерия. Так же методика позволяет сравнивать варианты перевозки одним типом нетягового подвижного состав и устанавливает условия, при которых его использование будет наиболее эффективно как для клиента, так и для перевозчика. Применение представленной методики позволит оценить эффективность данного типа вагонов при перевозке массовых грузов как на экспорт, так и во внутригосударственных перевозках.

The article presents the results of a study of the efficiency of bulk cargo transportation in various types of rolling stock. It is established that the technology of transportation of coal cargoes for export in containers with an Open Top roof has been applied. Despite a number of advantages of such technology, there are also disadvantages that are significant for destinations with a shortage of throughput and carrying capacity. The choice of the type of rolling stock should be based on a number of restrictions, such as the norm of mass and length of the train and can be carried out according to natural or cost criteria, depending on the side of the beneficiary - the carrier or the client. The study presents a technique that allows to maximize or minimize the value of the selected criterion. The methodology also allows you to compare transportation options with one type of non-traction rolling stock and establishes the conditions under which its use will be most effective for both the client and the carrier.

En el presente trabajo, se procedió a analizar dos microclimas de la ciudad de Posadas. Se ha caracterizado el barrio Centro y el barrio Itaembé Miní de la ciudad de Posadas. Además, se analizó la temperatura en dos puntos, uno en cada barrio, donde se encuentras estaciones meteorológicas. Este análisis se realizó para poder determinar si existe una diferencia estadísticamente significativa entre ambas mediciones. Las mediciones realizadas son extraídas de la Oficina de Prevención ante Desastres Naturales (OPAD). Se ha realizado un análisis por muestras apareadas para poder determinar si ambas mediciones son similares o no. Poder determinar diferencias entre las temperaturas de ambas mediciones pueden deberse a un efecto denominado Isla de Calor Urbana (ICU). Este efecto está presente debido al aumento de la construcción de las ciudades y de la actividad antropocéntrica. Como resultado, se han encontrado diferencias significativas. La estación meteorológica del Centro registró una temperatura superior que la temperatura registrada en la estación meteorológica de Itaembé Miní durante el período analizado (mayo 2022 en horarios de medianoche y mediodía).

Published: December 2024

Este artigo investiga o comportamento das proteções IEEE C37.2 50/51 e 87T com o protocolo Sampled Values (SV) da IEC 61850-9-2, considerando a integridade dos dados. Utilizou-se a representação computacional de uma subestação de distribuição real no simulador Opal-RT OP 5700, com testes de software-in-the-loop. Os valores de corrente foram enviados das TCs para as Merging Units (MU) virtuais, que publicaram pacotes de dados SV em uma rede ethernet, sendo os IEDs virtuais programados para assinar esses dados. Diversos problemas de transmissão, como atraso, perda ou duplicação de pacotes, foram simulados. Os testes mostraram que a proteção 87T foi afetada tanto em operação normal quanto em situações de falta, enquanto a proteção de sobrecorrente 50/51 manteve-se estável em condições normais, mas foi comprometida em situações de falta e degradação dos frames SV. Conclui-se que a integridade dos pacotes de dados SV é crucial para o funcionamento eficiente das proteções.
Structured expert elicitation on disinformation, misinformation, and malign influence: Barriers, strategies, and opportunities
Authors: Kruger Ariel , Saletta Morgan , Ahmad Atif , Howe Piers
Published: December 2024

We used a modified Delphi method to elicit and synthesize experts’ views on disinformation, misinformation, and malign influence (DMMI). In a three-part process, experts first independently generated a range of effective strategies for combatting DMMI, identified the most impactful barriers to combatting DMMI, and proposed areas for future research. In the second stage, experts deliberated over the results of the first stage and in the final stage, experts rated and ranked the strategies, barriers, and opportunities for future research. Research into intervention effectiveness was a strategy that received the highest level of agreement, while robust platform regulation was deemed the strategy of highest priority to address. They also identified distrust in institutions, biases, political divisions, relative inattention to non-English-language DMMI, and politicians’ use of DMMI as major barriers to combatting DMMI. Vulnerability to DMMI was chosen by experts as the top priority for future study. Experts also agreed with definitions of disinformation as deliberately false/misleading information and misinformation as unintentionally so.
Applying Implementation Research Principles to Enhance Cancer Detection in Southern Africa: A Case Study of AWACAN-ED
Authors: Ogweno Stephen
Published: December 2024

Effective implementation research is critical for addressing global health challenges, particularly in low- and middle-income countries (LMICs) where resource constraints and health disparities are prevalent. The African aWAreness of CANcer & Early Diagnosis (AWACAN-ED) project is an NIHR-funded Global Health Research Group focusing on Advancing Early Diagnosis of Cancer in Southern Africa. This project exemplifies the application of implementation research principles to improve cancer diagnosis and treatment in Southern Africa. This paper explores how AWACAN-ED aligns with seven key principles of implementation research: local relevance and contextualization, stakeholder engagement, ethical considerations, monitoring and evaluation, communication and dissemination, sustainability, and capacity building with supportive supervision. AWACAN-ED focuses on developing e-tools for early cancer detection while integrating its activities into existing healthcare frameworks, ensuring long-term sustainability and scalability. It prioritizes local stakeholder engagement, ethical rigour, and robust capacity-building initiatives to empower researchers and health practitioners. The project employs comprehensive monitoring and evaluation mechanisms to adapt interventions and maximize impact. AWACAN-ED’s ability to translate research findings into actionable policies highlights its policy-relevant research approach, creating frameworks for cancer costing and management that influence health system strengthening. By examining the successes and challenges of AWACAN-ED, this paper provides valuable insights into the effective implementation of health initiatives in LMICs. The findings emphasize the importance of sustainable planning, community engagement, and adaptive learning to achieve meaningful, lasting health outcomes. AWACAN-ED serves as a model for cancer care implementation research and underscores the potential of similar programs to address critical health issues globally

Authors: Clotilda A. M. D. , Vithanage G. V. R. K. , Lakshika D. D.
Published: December 2024

Cancer is a burning problem in the modern health field. In this research mainly we focused on how we can treat for a cancer by using chemotherapy and immune therapy as individual monotherapies and as a combined therapy. In previously, researchers have constructed mathematical models to analyse the combined therapy treatment with saturation effects for immune therapy treatment but here we introduce mass action kinetics for immune therapy and this model reflects as a continues attacking process to tumour cells by immune cells with the help of chemotherapy drug. We introduce some threshold levels which we can remove cancer completely and control the cancer in a constant level.

This paper delves into two factors that potentially increase the inaccuracy of the gaze signal, namely, 1) Pupil-size changes and the pupil-size artefact (PSA) and 2) the putative inability of experienced individuals to precisely refixate a visual target. Experiment 1 utilizes a traditional pupil-CR eye tracker, while Experiment 2 employs a retinal eye tracker, the FreezeEye tracker, eliminating the pupil-based estimation. Results reveal that the PSA significantly affects gaze accuracy, introducing up to 0.5

Corrections based on the relation between pupil size and apparent gaze shift substantially reduce inaccuracies, underscoring the PSA’s influence on eye-tracking quality. Conversely, Experiment 2 demonstrates humans’ precise refixation abilities, suggesting that the accuracy of the gaze signal is not limited by human refixation inconsistencies.

Objective. The objective of this study was to explore the effect of transcranial direct current stimulation (tDCS) combined with hand grip strengthening exercises in amateur badminton players. Materials and methods. This study was a participant-blinded, randomized controlled trial. Thirty amateur badminton players, aged 8–20 years with a minimum playing experience of 6 months, were included. Hand grip strength (HGS) was measured at baseline, Day 1, Day 4, Day 8, and Day 12. Results. The results of the present study showed no significant difference in hand grip strength between the groups. The overall interaction effect between the groups was found to be insignificant (p = 0.722). However, the overall interaction effect within the group was significant (p = 0.011*). Multiple comparisons revealed the greatest improvement in HGS at Day 12 compared to the baseline value. Conclusion. The application of anodal tDCS combined with HGS training was ineffective in improving hand grip strength in amateur badminton players.

Background. Sphenoorbital meningioma (SOM) often presents with proptosis and vision impairment due to optic nerve compression within the optic canal, primarily caused by hyperostosis. This study aims to highlight the importance of optic canal decompression during SOM surgery. Fourteen patients with SOM and vision impairment underwent surgery focused on adequate optic canal decompression. Vision was evaluated preoperatively, at three months, and at six months postoperatively. Preoperative vision loss was confirmed to be due to optic nerve compression by surrounding hyperostotic bone. Six-month postoperative evaluations showed significant improvement in visual acuity in twelve of the fourteen patients. SOM frequently occurs in women in their 50s. Early surgical intervention is crucial for patients with visual symptoms to achieve better outcomes. While cosmetic correction of proptosis is important, the primary surgical goal should be decompression of the optic nerve.

Background. Arteriovenous malformations (AVMs) are abnormal tangles of blood vessels that connect arteries and veins, disrupting normal blood flow and oxygen circulation. Although AVMs can occur in various regions of the brain, their presence in the occipital lobe and their potential to induce generalized convulsive status epilepticus (GCSE) are considered rare. This case report aims to describe a unique presentation of GCSE induced by an AVM located in the occipital lobe. Case report. A 64-year-old patient was brought to the emergency department in an unconscious state after experiencing two seizures. Whole-body convulsions lasting 5–6 minutes were observed, despite the absence of a prior seizure history. Before the seizures, the patient reported symptoms of weakness, vomiting, and severe dizziness, although no sensory loss was noted. Post-seizure, cyanosis and snoring were present, and the patient remained unconscious and confused, without limb weakness or slurred speech. Physical examination revealed postictal confusion and cyanosis. Imaging studies, including MRI, showed an abnormal flow void on T2 FLAIR in the right occipital lobe, accompanied by multiple niduses. Further evaluation via MRA confirmed the presence of an AVM in the right occipital region, with feeding from the posterior cerebral artery (P2 branch) and draining into the right basal and frontal veins. Conclusions. This case highlights the need for awareness of rare etiologies, such as AVMs in the occipital lobe, in patients with new-onset seizures. Prompt diagnosis and appropriate management are essential for reducing the risks associated with GCSE and improving the quality of life of affected individuals.

New Materialism and Wuthering Heights
Authors: Özsevgeç Yıldırım , Erkan Enfal
Published: December 2024

Wuthering Heights (1847) has been regarded as a Victorian-Era novel due to the themes it has dwelled on. Emily Brontë, by bringing class differences, women’s role in society, and the perception of men’s superiority into the novel, has appealed to a wide readership. Critics and academics have frequently discussed this work for nearly 200 years. While the work has been analyzed by various approaches, its romantic, social, and gothic aspects are generally emphasized. However, Brontë prioritized setting and atmosphere while creating the plot and included plenty of geographical descriptions. She places great emphasis on nature in the setting, highlighting the influential role of each natural element on humans, who are integral parts of the natural world. New Materialism is the approach that argues that the “things” that we consider inert and passive in nature are actors of the network that creates each phenomenon. According to new materialism, it is the objects around one that they are in constant contact with that form their thought structure and motivate them. The functions of these objects and even their mere existence motivate people. When examined through this perspective, the idea arises that “things” considered inanimate may be “vibrant matters”. On the other hand, Wuthering Heights constitutes a comprehensive example to show the vibrant agency of nature. In this study, we analyze Wuthering Heights from a new materialist perspective and use the concepts of actor-network theory, intra-action, and vibrant matter as methods.

We present photometric and spectroscopic observations of SN 2023fyq, a Type Ibn supernova (SN) in the nearby galaxy NGC 4388 (D ≃ 18 Mpc). In addition, we trace the 3 yr long precursor emission at the position of SN 2023fyq using data from DLT40, ATLAS, Zwicky Transient Facility, ASAS-SN, Swift, and amateur astronomer Koichi Itagaki. The double-peaked postexplosion light curve reaches a luminosity of ∼1043 erg s−1. The strong intermediate-width He lines observed in the nebular spectrum imply the interaction is still active at late phases. We found that the precursor activity in SN 2023fyq is best explained by the mass transfer in a binary system involving a low-mass He star and a compact companion. An equatorial disk is likely formed in this process (∼0.6M
⊙), and the interaction of SN ejecta with this disk powers the second peak of the SN. The early SN light curve reveals the presence of dense extended material (∼0.3M
⊙) at ∼3000R
⊙ ejected weeks before the SN explosion, likely due to final-stage core silicon burning or runaway mass transfer resulting from binary orbital shrinking, leading to rapid-rising precursor emission within ∼30 days prior to explosion. The final explosion could be triggered either by the core collapse of the He star or by the merger of the He star with a compact object. SN 2023fyq, along with SN 2018gjx and SN 2015G, forms a unique class of Type Ibn SNe, which originate in binary systems and are likely to exhibit detectable long-lasting pre-explosion outbursts with magnitudes ranging from −10 to −13.
New Radio Observations of the Supernova Remnant CTA 1
Authors: Do Tam , Kothes Roland , Hill Alex S. , Gray Andrew , Reich Patricia , Reich Wolfgang
Published: December 2024

We present new radio images of the supernova remnant (SNR) CTA 1 at 1420 and 408 MHz, and in the 21 cm line of H i observed with the Dominion Radio Astrophysical Observatory Synthesis Telescope and at 1420 MHz observed with the Effelsberg 100 m telescope. We confirm previously described continuum features and elaborate further on filamentary features identified using the high-resolution (1′) maps from these new observations. We investigate the abrupt change in sign of rotation measure (RM) across the SNR, using the linear polarization observations in the four bands around 1420 MHz. Following X. H. Sun et al.’s (2011) investigation, we both confirm that the distribution of signs of the RMs for extragalactic sources in the area appears to match that of the shell, as well as combine the data from the four bands to estimate the relative depolarization and the intrinsic rotation measure of the SNR. We do not conclusively reject X. H. Sun et al.’s (2011) claim of a Faraday screen in the foreground causing the distribution of RMs that we observe; however, we do suggest an alternative explanation of a swept-up stellar wind from the progenitor star with a toroidal magnetic field. Finally, we expand on the analysis of the H i observations by applying the Rolling Hough Transform to isolate filamentary structure and better identify H i emission with the SNR. Further constraining the H i velocity channels associated with CTA 1, we use more recent Galactic rotation curves to calculate an updated kinematic distance of 1.09 ± 0.2 kpc.

Published: December 2024

The star HD 94509 was recognized as an extreme example in the class of Be and shell stars because of its unusual late-type shell spectrum and anomalous line profiles. Using high-resolution and high-signal-to-noise ratio spectroscopy obtained with FIberfed Echelle Spectrograph on Nordic Optical Telescope, we investigate whether HD 193182 is a similarly extreme Be-shell star, as suggested by microphotometer tracings obtained in the 1920s and 1940s. Indeed, both stars turn out to be very similar in terms of photospheric and shell spectra. A basic model atmosphere analysis of HD 193182 is performed using non-LTE line formation calculations.

The Anoa, including the Mountain Anoa (Bubalus quarlesi) and the Lowland Anoa (Bubalus depressicornis) according to current taxonomy, are endangered bovid species endemic to the tropical island of Sulawesi. They are grouped in their own subgenus Anoa. The historical biogeography and phylogeny of this subgenus have not been well characterized. There are two hypotheses describing the colonization routes of large mammals in Southeast Asia: land-bridges and insular route. The present study aimed to understand the molecular phylogeny and test the historical colonization route of Anoa. A total of 71 mitochondrial DNA (cyt b gene and control region) sequence datasets from Anoa and other related species were analyzed. Molecular phylogeny reconstruction was done using a Bayesian inference model. Calibration points were used to estimate divergence time in Anoa based on a Bayesian phylogeny tree. Estimation of ancestral areas in Anoa ancestors using Reconstruct Ancestral State in Phylogenies was carried out to test the Anoa colonization route. The phylogenetic tree revealed the existence of two groups of Anoa, lowland and mountain Anoa, which diverged during the Middle Pleistocene 1.42 Mya (highest posterior density interval: 1.14–1.71 Mya). The Sundaland area is the most probable (P > 0.7) ancestral area for the Bubalus spp. in the Indonesian archipelago. The most probable Anoa colonization route appears to be through land-bridges, which geological records indicate formed between Sundaland and Sulawesi during the Pleistocene.

Published: December 2024

A 77-year-old woman presented with metastatic urothelial carcinoma as an elbow mass. To our knowledge, this is only the third reported case of urothelial carcinoma metastasizing to the upper extremity. The presence of metastatic disease at the time of diagnosis of urothelial carcinoma is rare, with metastases to the upper extremities even less common. This case is interesting given that the mass occurred after a direct trauma, causing a delay in diagnosis. It highlights the importance of a multidisciplinary oncology approach, and the need for more research to understand the biology of metastases. [

Authors: Jawarneh Yousef , Yasmin Humaira , Mahnashi Ali M.
Published: December 2024

In this paper, we use the Riccati–Bernoulli sub-ODE method in conjunction with the Bäcklund transformation to find out the exact solutions of the nonlinear time–space fractional Bogoyavlenskii equation. The obtained solutions encompass multiple kink solitary wave solutions that are quite unique and important in addition to solutions presented in hyperbolic, trigonometric, and rational function forms. This equation describes central factors influencing its behavior including fluid dynamics in shallow water waves and plasma, which demonstrates our conclusions have broad applications for such systems. We also study the effect of the fractional order parameter ($ \alpha $) on solutions and plot their behavior using MATLAB in two dimensions. This work also contributes to the knowledge of the physical structures of the fractional Bogoyavlenskyi equation apart from showcasing the potential of the Riccati–Bernoulli sub-ODE method when applied to nonlinear fractional differential equations.
Investigation of biocorrosion on mild steel in cooling tower water and its inhibition by C. sativum

Published: December 2024

The primary goal of this investigation was to evaluate the effect of Coriandrum sativum extract on mitigating corrosion caused by Staphylococcus aureus, Klebsiella pneumonia, and Bacillus subtilis on metal samples. Analytical methods including SEM, FTIR, and XRD examination were used on the metal surface to determine the mechanism underlying corrosion inhibition. Impedance studies and Nyquist plots were used to support the role of green inhibitors in biocorrosion control. Based on analytical examinations, the corrosion patterns in some pitted zones showed a substantial link between microbial metabolites and the chemical composition of the metal surface. The presence of microbial metabolites caused the metallic surface to become more porous and permeable, changing the surface's structural makeup. In all three bacteria, 30 ppm of plant extract was found to be the maximum concentration that inhibited microbial corrosion. The coupons submerged in the control solution lost weight, indicating that the addition of the inhibitor caused a brief increase in corrosion rates before they declined.

Međudržavno posvojenje je nedavno zaokupilo dosta pozornosti u Hrvatskoj, kako u medijskom prostoru tako i u znanstvenom i stručnom radu. Međutim, sustavnom i planskom uređenju međudržavnog posvojenja nadležna tijela i dalje nisu pristupila. Stoga je cilj ovog rada ponuditi neke opcije u daljnjem uređenju ovog vrlo specifičnog instituta u Hrvatskoj. S tim ciljem, rad prvo definira međudržavno posvojenje obrazlažući njegove vrste, zatim se daje prikaz uređenja međudržavnog posvojenja u Hrvatskoj nakon čega se razmatraju razni pristupi koje je moguće poduzeti u pogledu međudržavnog posvojenja. U radu se ističu dodatno uređenje ovog instituta, mogućnost ograničenja i moratorija međudržavnog posvojenja, pojačana suradnja s drugim državama te informiranje potencijalnih posvojitelja uz poticanje konvencijskih posvojenja u odnosu na nekonvencijska. Zaključno se ističe nužnost promišljenog pristupa koji bi zahtijevao procjenu temeljenu na iskustvima praktičara te znanjima teoretičara iz raznih pravnih područja te struka koje se bave zaštitom djece.

Early diagnosis of diabetic complications based on risk factors is essential but remains understudied, particularly in the context of multi-label classification (MLC). This study leverages data from the behavioral risk factor surveillance system (BRFSS) from 2016 to 2021 to classify seven diabetes complications using MLC techniques combined with multiple machine learning (ML) models. We analyzed 33 variables per dataset year after thorough statistical analysis and preprocessing. Seven ML models were employed: Artificial neural network (ANN), random forest (RF), decision tree (DT), K-nearest neighbors (K-NN), naïve Bayes (NB), support vector machine (SVM), and deep neural network (DNN). We compared two MLC frameworks: problem transformation and algorithm adaptation. The performance of the models was evaluated using several metrics, and feature importance for each complication was analyzed. Our results indicate that the algorithm adaptation framework, particularly with DNN models, outperforms problem transformation. This highlights the potential of this approach for improving classification performance in complex diseases with multiple complications.

Authors: González Hernando , Arizmendi Carlos Julio , Giraldo Beatriz F.
Published: December 2024

Spontaneous breathing trials (SBTs) represent a pivotal phase in the weaning process of mechanically ventilated patients. The objective of these trials is to assess patients’ readiness to resume independent breathing, thereby facilitating timely weaning and reducing the duration of mechanical ventilation (MV). Nevertheless, accurately predicting the success or failure of SBT remains a significant challenge in clinical practice. This study proposes a healthcare system that employs machine learning techniques to predict the outcome of SBT. The model is trained on respiratory flow and electrocardiogram (ECG) signals, employing the non-uniform discrete Fourier transform (NUDFT) for frequency domain analysis. The SBT prediction model has the potential to significantly enhance clinical decision-making by enabling the early identification of patients at risk for SBT failure, achieving an accuracy of 84.4 ± 3.2%.

The hip femoral stem is vital in ensuring patient support and mobility, and research into the femoral stem is critical for improving the durability and strength of orthopedic prostheses. Using the finite element method, this paper evaluates a femoral stem’s static, transient, and fatigue behaviors using three different materials: Ti-6Al-4V, CoCr alloy, and AISI 316L. ANSYS Mechanical software was used to perform the static analysis, evaluate deformations and stresses, and perform the transient analysis to simulate dynamic loading conditions. In addition, a fatigue analysis was conducted to determine the resistance to repetitive load cycles. The results showed that the stresses and strains in the transient analysis were higher than in the static analysis because the transient analysis considers dynamic and time-varying loads. In addition, the Ti-6Al-4V material exhibits higher fatigue resistance, a significantly longer service life, and lower stresses in the static and transient range. These findings reaffirm the importance of selecting materials that balance stiffness, structural strength, and fatigue to optimize the performance and durability of femoral implants.
