Published: December 2024

Los territorios del actual municipio de Malinalco se han caracterizado por su gran diversidad de paisajes agrícolas. En el presente siglo, se han dado importantes transformaciones socioeconómicas que han impactado en la pérdida de espacios agrícolas o en sutransformación productiva. Por ejemplo, el creciente turismo residencial y las nuevas tendencias de producción agrícola han provocado la pérdida o transformación de zonas agrícolas en torno a los principales centros de población y la desaparición de las huertas. El objetivo de la investigación fue determinar los cambios ocurridos en la ocupación del suelo agrícola en el municipio de Malinalcoentre 1995 y 2022, así como explicar dichos cambios de acuerdo con la percepción de los productores locales. Se partió de un enfoque metodológico mixto, basado en el análisis cartográfico y en la aplicación y análisis de entrevistas a profundidad. Entre los principaleshallazgos destacan el estancamiento de la producción de maíz tanto en zonas de riego como de temporal, la notable pérdida de loshuertos familiares, la incipiente aparición de la agricultura protegida y el considerable crecimiento del cultivo de aguacate y agave mezcalero. El análisis de los datos textuales compilados refleja que, para los productores agrícolas, las transformaciones que están ocurriendo a nivel territorial y productivo los colocan en condiciones de fragilidad social, económica y ambiental.

What Is the issue?

Data on trends in the pharmaceutical market remain limited. We offer an annual update on estimated drug purchases in Canada and highlight key factors that could impact future spending.

What Did We do?

We conducted a retrospective time-series analysis of annual estimated drug purchases across Canada between 2001 and 2023 using IQVIA’s Canadian Drugstore and Hospital Purchases Audit.
We calculated total estimated drug purchases and relative percentage change annually, stratified by sector (retail and hospital), and forecast annual spending to 2025.

What Did We Find?

Total estimated drug purchases for 2023 were approximately $43.5 billion, 13.7% higher than in 2022.
Overall, expenditure on the top 25 high-cost drugs accounted for 32.5% and 53.3% of total spending in the retail and hospital sectors, respectively.
Pharmaceutical spending has grown over the past 2 decades, with an annual average growth of 5.8% and 8.2% in the retail and hospital sectors, respectively.
Drug expenditure in the retail sector is expected to increase annually by 10.9% to 10.1% and spending within the hospital sector is expected to increase by 14.6% to 12.9% for 2024 and 2025, respectively.

What Does This Mean?

The accelerated growth in overall estimated drug purchases is likely driven by the increasing use of new diabetes and obesity treatments.
Continued growth in drug purchases is projected across the Canadian market, which will be influenced by new approvals of specialty and oncology drugs, as well as generic and biosimilar versions of the top 25 drugs.
Without measures to address this ongoing increase in pharmaceutical spending, there may be a need to reallocate funds from other public sectors or shift costs to private industry and patients.

Published: December 2024

Abstract. Community structure of microzooplanktonic ciliate in size spectrum, biodiversity and biotic-abiotic interplay are essential components for unraveling their ecological role in marine ecosystems, yet remain challenging to elucidate on a global scale. To address this knowledge gap, we conducted field observational studies across five temperature zones (North Frigid Zone, NFZ; Sub-Arctic Zone, SAZ; North Temperate Zone, NTZ; Torrid Zone, TZ; South Frigid Zone, SFZ). Our analysis revealed that a sharply decline in ciliate abundance and biomass occurred at 100 m layer, with distinct vertical distribution patterns observed in each climate region. Moreover, ciliate size spectra exhibited a decrease trend from small to large size spectra, with steeper slopes observed in the NFZ and SFZ compared to the other temperature zones. Furthermore, an anti-phase relationship between ciliate abundance and tintinnid biodiversity was observed in latitudinal direction, with the TZ and bipolar seas characterized by the highest biodiversity and abundance, respectively. Moreover, a multivariate biota-environment analysis indicated that temperature exert a primary influence on microzooplanktonic ciliates in the global marine ecosystem, and the bottom-up control play a key role in shaping ciliate community. In conclusion, these results underscore the unprecedented divergences in ciliate trait structure among five temperature zones and can be generalised for assessing the potential effects of climate change on pelagic microzooplankton in future marine realm.

Published: December 2024

Abstract. Understanding and modeling the turbulent transport of surface layer fluxes plays a critical role in a numerical weather forecasting model. The presence of heterogeneous surface obstacles (buildings) that have dimensions comparable to the model vertical resolution requires further complexity and design in the planetary boundary layer (PBL) scheme. In this study, we develop the numerical method to couple one of the recently validated PBL schemes, TKE-ACM2, with the multi-layer Building Effect Parameterization (BEP) model in WRF. Subsequently, the performance of TKE-ACM2+BEP has been examined under idealized convective atmospheric conditions with a simplified building layout. Furthermore, its reproducibility is benchmarked with one of the state-of-the-art large-eddy simulation models, PALM, which can explicitly resolve the building aerodynamics. The result indicates that TKE-ACM2+BEP outperforms the other operational PBL scheme (Boulac) coupled with BEP by reducing the bias in both the potential temperature (θ) and wind speed (u). Following this, real case simulations are conducted for a highly urbanized domain, i.e., the Pearl River Delta (PRD) region in China. The high-resolution wind speed LiDAR observations suggest that TKE-ACM2+BEP can mitigate the overestimation in the lower part of the boundary layer compared to the Bulk method at a LiDAR site located in a densely built environment. In addition, the surface temperature and relative humidity can be improved in TKE-ACM2+BEP at surface stations in urbanized areas compared to TKE-ACM2 without BEP. However, it is revealed that BEP may not always imply a better reproduction of surface wind speed as it could exert excessive aerodynamic drag.
A modular wind profile retrieval software for heterogeneous Doppler lidar measurements
Authors: Erdmann Anselm , Gasch Philipp
Published: December 2024

Abstract. Retrieving wind profiles from Doppler lidar radial velocities requires processing software tools. The heterogeneity of Doppler lidar types and data acquisition settings, as well as scan patterns applied for wind profiling, make wind profile processing challenging. Addressing this challenge, a new modular open-source wind profile retrieval software is presented: the Atmospheric Profile Processing toolKIT (AtmoProKIT). The software calculates quality controlled wind profiles from heterogeneous Doppler lidar data, i.e. independent of the system type, data acquisition settings or the scan pattern applied. Ingestion of heterogeneous data is enabled by the definition of a standardized level 1 data format for the measurements, from which level 2 wind profiles are retrieved. Processing flexibility is enabled through the combination of modular processing steps in module chains. Modifications are possible by individually arranging modules, adding calculation modules or adjusting processing parameters. The documentation of the processing steps in the result’s metadata ensures the traceability of the results. A standard module chain is presented, which allows for straightforward wind profile retrieval for common Doppler lidar measurement scenarios without the need for coding. The results provided by the standard module chain are validated against radiosondes for three common Doppler lidar systems in differing atmospheric conditions. AtmoProKIT is provided as open-source Python code and includes demonstration examples, allowing for an easy use and future collaborative modification.
Modeling hydropower operations at the scale of a power grid: a demand-based approach
Authors: Baratgin Laure , Polcher Jan , Dumas Patrice , Quirion Philippe
Published: December 2024

Abstract. Climate change and evolving water management practices may have a significant impact on hydropower generation. While hydrological models have been widely used to assess these effects, they often present some limitations. A major challenge lies in modeling the release decisions for hydropower reservoirs, which result from intricate trade-offs, involving power sector dispatch, competing water uses, and the spatial allocation of power generation within the grid. To address this gap, this study introduces a novel demand-based approach for integrating hydropower within the routing module of land surface models. First, hydropower infrastructures are located in coherence with the hydrological network, and links are built between hydropower plants and their supplying reservoirs to explicitly represent water transfers built for hydropower generation. Then, coordinated dam operation is simulated by distributing a prescribed electric demand to be satisfied by hydropower across the different power plants within the power grid, while considering the operational constraints associated with the multipurpose nature of most dams. To validate this approach, we implement the framework within the water transport scheme of a land surface model and assess it with the case study of the French electrical system. We drive the model with a high-resolution atmospheric reanalysis and prescribe the observed national hydropower production as the total power demand to be met by hydropower infrastructures. By comparing the simulated evolution of reservoir stocks to observations, we find that the model simulates realistic operations of reservoirs and successfully satisfies hydropower production demands over the entire period. We also highlight the roles of uncertainties in estimated precipitation and of the limited knowledge of hydropower infrastructure in the estimation of production. Finally, we show that such an integration of hydropower operations in the model improves the simulations of river discharges in mountainous catchments affected by hydropower.

Paleoclimate reconstructions of Durankulak Lake (Northeastern Bulgaria) during the last 6000 years using pollen analysis and modern analog technique (MAT)
Authors: Vergiev Stoyan
Published: December 2024

The aim of the present study is to reconstruct the palaeoclimate variables in the Durankulak Lake Region (Northeastern Bulgaria) during the last 6000 years, based on the pollen analysis from lacustrine core DK-1 and using modern analog technique (MAT). Pollen data was used for reconstructions of four parameters: average annual temperature, average temperature of the warm and cold half-year and average annual precipitation. Three climatic intervals were defined. During the first interval (6000–5000 cal. BP), the highest values of the thermal parameters were recorded, which coincides with the Holocene climatic optimum. Precipitation is relatively high, but below assumed averages for the Atlantic period. The curves of the thermal parameters in the interval 5000–3000 cal. BP show dynamics and a decreasing trend. The last time interval (after 3000 cal. yr. BP) is characterized by the uniformity of the climatic parameters, which show almost identical values.
The change of the child’s habitual residence
Authors: Vrabie Dina
Published: December 2024

Every child has a habitual residence, which indicates his special connection with a certain place. Although the phrase contains the term „ordinary“, it is certain that the residence can be changed. On this interference in the child’s life and psychological comfort, the parents would decide together, in order to reduce the suffering caused to the child by the said process. In essence, changing the child’s habitual residence can be either legal or illegal (illegal). A legal change of the child’s habitual residence is not the subject of our research, as it does not involve a breach of custody right, and therefore does not fall under the scope of the child return procedure. Attention is drawn to the way in which the child’s habitual residence is changed illegally, due to the fact that as a result of an illegal child’s movement or detention on the territory of another state, he can acquire a new habitual residence, subject to certain conditions.

Published: December 2024

In this article, the conditions for obtaining monocrystals of CuGa2.5In2.5S8, were investigated, their optical absorption edge, electrical and photoelectric properties. Using the criteria for the formation of new layered chalcogenides with octahedral and tetrahedral coordination of cations, it was hypothesized that due to the replacement of half of the In atoms in the CuIn5S8 spinel with Ga, which has a pronounced tendency to occupy the tetrahedral B sites in a denser packing of S atoms, a layered phase is formed. Melting of a stoichiometric mixture of Cu+2.5Ga+2.5In+8S led to the synthesis of a previously unknown single-phase product with a layered crystalline structure. Since copper, gallium, and indium sulfides are generally good photoconductors, it could be expected that the new compound would also exhibit high photosensitivity. The aim of this work was to investigate the conditions for obtaining of CuGa2.5In2.5S8 single crystals, their optical absorption edge, electrical and photoelectric properties.

Published: December 2024

. Современный этап развития металлургии характеризуется беспрецедентным вниманием к вопросам снижения эмиссии CO2. В качестве одного из путей снижения эмиссии CO2 рассматривается замена углерода водородом при выплавке чугуна при этом следует учитывать, что получение водорода также связано с выбросами углекислого газа. Степень использования CO при косвенном восстановлении в доменной печи составляет 28–38% в отличие от прямого восстановления, где степень использования в большей степени зависит от площади контакта восстановителя и оксидов. Перспективным направлением увеличения степени использования восстановительной способности углерода в доменной печи является применение рудоугольных брикетов. В работе рассмотрена эффективность использование рудоугольных брикетов при производстве ванадиевого чугуна с точки зрения снижения эмиссии СО2. Показано, что затраты углерода на прямое восстановление титаномагнетитового концентрата в 6 раз меньше, чем при косвенном. Применение рудоугольных брикетов в шихте доменных печей позволит снизить удельный расход углерода топлива при производстве ванадиевого чугуна, что приведет к снижению эмиссии CO2.

The current stage of development of metallurgy is characterized by unprecedented attention to issues of reducing CO2 emissions. As one of the ways to reduce CO2 emissions, the replacement of carbon with hydrogen in the smelting of cast iron is considered; however, it should be taken into account that the production of hydrogen is also associated with carbon dioxide emissions. The CO utilization rate for indirect reduction in a blast furnace is 28–38%, in contrast to direct reduction, where the utilization rate is more dependent on the contact area between the reducing agent and the oxides. A promising direction for increasing the degree of utilization of the reducing power of carbon in a blast furnace is the use of ore-coal briquettes. The paper examines the effectiveness of using ore-coal briquettes in the production of vanadium cast iron from the point of view of reducing CO2 emissions. It has been shown that carbon consumption for direct reduction of titanomagnetite concentrate are 6 times less than for indirect reduction. The use of ore-coal briquettes in the blast furnace charge will reduce the specific consumption of fuel›s carbon in the production of vanadium cast iron, which will lead to a reduction in CO2 emissions.

Published: December 2024

An important area in the work of the TB service is the search for integrated approaches in the treatment of patients with pulmonary tuberculosis. One of these approaches is the widespread use of methods of artificial pneumoperitoneum and endobronchial valvular bronchoblocation. The active use of surgical treatment can also be an effective technique.

The aim of the work is to study the effectiveness of the use of methods of artificial pneumoperitoneum and endobronchial valvular bronchoblocation as preoperative preparation in patients with pulmonary tuberculosis.

Materials and methods. The study included 295 patients: group 1 — patients treated with artificial pneumoperitoneum and endobronchial valvular bronchoblocation (n = 201); group 2 consisted patients who did not use these methods (n = 94).

Results. Operations with the smallest volume were significantly more often performed in patients of group 1a (34.8 %), compared with group 1b and group 2a (p1a–1b = 0.016, p1a–2a = 0.014). Large-volume surgery was significantly more often performed in patients of group 2 (41.1 %, p1a–2a = 0.028).

Discussion. The use of artificial pneumoperitoneum and endobronchial valvular bronchoblocation helps to reduce the volume of surgical intervention. Thus, in the group of patients after effective endobronchial valvular bronchoblocation and artificial pneumoperitoneum, lung resection within 1–2 segments was significantly more often used; whereas in the group of patients who did not use artificial pneumoperitoneum and endobronchial valvular bronchoblocation techniques, large-scale surgical interventions were more often resorted to.

Conclusion. The use of artificial pneumoperitoneum and endobronchial valvular bronchoblocation helps to increase the effectiveness of treatment and reduce the volume of surgery, preventing significant damage to the loss of lung tissue.

Mechanical behavior evaluation and degradation mechanism for HMPE yarns under fatigue abrasion tests
Authors: Belloni Eduarda da Silva , Cruz Daniel Magalhães da , Guilherme Carlos Eduardo Marcos
Published: December 2024

Offshore oil exploration in deeper waters has necessitated the development of lighter mooring systems to replace traditional steel cable and chain platforms. This study focuses on evaluating the mechanical behavior and fatigue degradation mechanism of high modulus polyethylene (HMPE) fibers in yarn-on-yarn abrasion tests. Initial characterization tests, including linear density, rupture force, and thermal analysis, were conducted on HMPE yarns. Yarn-on-yarn abrasion tests were performed under dry, wet, and salty conditions, with varying loads, while statistical analysis examined the influence of environmental factors and load levels on yarn performance. Scanning electron microscopy (SEM) analysis provided insights into material degradation mechanisms. Results showed superior performance in freshwater-immersed yarns due to cooling and lubrication effects, while dry conditions led to material melting. SEM analysis revealed critical degradation zones, particularly in interwoven regions, where increased friction and heat concentration caused material fusion. Degradation evolution mechanisms highlighted fatigue-induced rupture of yarns, knot formation, and material melting near failure points. This comprehensive analysis enhances understanding of HMPE yarn performance and degradation in offshore mooring applications, laying the groundwork for developing advanced mooring systems capable of withstanding deep-sea environments.

Authors: Lee Joon Kyu , Lee Jong Cheon , Choi Jong Min , Lee Byoung Koo
Published: December 2024

This study investigates the generalized stiffness of laterally functionally graded materials (LFGMs) and applies these findings to dynamic beam elements. The generalized stiffnesses of LFGM, coupled with material and cross-sectional properties such as flexural and axial rigidity, mass per unit length, and mass-moment of inertia, are explicitly formulated. In the context of LFGM, material properties depend on an asymmetrical power law function with respect to cross-sectional depth. An example of the generalized numerical stiffness of a circular cross-section is provided for various material properties. To illustrate the application of generalized stiffness to dynamic beam elements, free vibration of LFGM beams with rotary inertia is considered. The dimensionless differential equation governing the free vibration of such beams is derived and numerically solved to obtain natural frequencies and corresponding mode shapes. Numerical results demonstrate a good consistency with the finite element method.
Hybrid-boosted model with an approach inspired by a mixture of experts for 5G energy consumption
Authors: Zimmermann Rafael Sudbrack
Published: December 2024

The advancement of 5G networks has brought significant innovations in terms of services and technologies but this has also imposed challenges related to energy consumption. Over 70% of energy consumption was projected to be attributed to Radio Access Networks (RANs), specifically Base Stations (BSs), with data centers and fiber transport contributing to a lesser extent. The objective of this study was to optimize the parameters of BSs and energy-saving methods, providing a deep understanding of how these elements influence energy consumption. This study introduces a hybrid-boosted ensemble model tailored for predicting energy utilization in 5G base stations. The methodology merges ridge regression for linear trend analysis, XGBoost to tackle non-linear intricacies, and a final refinement strategy built upon a mixture of experts. Preliminary results demonstrate the model's capability to adjust to new and diverse data scenarios, achieving up to a 31.94% improvement in 5G energy forecasting compared to traditional models. This research constitutes a pivotal initiative in confronting adaptability hurdles in 5G energy predictions, setting a foundation for subsequent inquiries in this essential domain.

Published: December 2024

Modeling network communication environments with Graph Neural Networks (GNNs) has gained notoriety in recent years due to the capability of GNNs to generalize well for data defined over graphs. Hence, GNN models have been used to abstract complex relationships from network environments, creating the so-called digital twins, with the objective of predicting important quality of service metrics, such as delay, jitter, link utilization, and so on. However, most previous work has used synthetic data obtained with simulations. The research question posed by the "ITU Graph Neural Networking Challenge 2023" is whether GNN models are capable of estimating the mean per-flow delay network, using data from a real network environment. The solution presented in this paper achieved first place in the mentioned challenge. It adopted a GNN based on multiple-stage message passing and the attention mechanism to predict the mean per-flow delay. Furthermore, feature selection was used to choose a reasonable subset of input parameters. The developed GNN model achieved a mean absolute percentage error under 20.1% in the challenge test dataset, which was composed by network conditions not used in the training dataset.
Application of task-oriented dialogue in operations for future networks to business
Authors: Gao Fang , Liu Weilin , Wang Chengli , Zhang Yanhua
Published: December 2024

At present, the network operation services provided by operators for to business (toB) customers have customer friendliness issues mostly affected by manual input. The limitations are reflected in four aspects: time consumption and understanding differences in the process of customer intention communication, waiting time and lack of process transparency. Therefore, in order to provide a more automatic, standard, concise and user-engaged method on operations for future networks in the toB field, this paper proposes applying a task-oriented dialogue system to the network operation task processing. The most significant advantage is that it makes possible for industry customers to participate directly in and facilitate their task completion process together with the system by several turns of dialogue. The conventional pipeline structure which combines both neural networks and rules is appropriate for meeting the above requirements for providing unified natural language understanding of intent, tracking dialogue state and generating actions of reply or command. With the help of a knowledge database and a network management system, the dialogue system provides users with more detailed operation information, which directly promotes user participation and transparency of the whole service process.

Authors: Cedaryana C. , Safria Dhuha
Published: December 2024

High turnover rates can lead to losses for a company. The turnover phenomenon begins with turnover intention, which is influenced by several factors, including job satisfaction and work environment. This study quantitatively analyzes the influence of job satisfaction and work environment on employee turnover intention at PT. XYZ. Involving 62 respondents and using multiple linear regression analysis, the study results show that both job satisfaction and work environment, partially and simultaneously, have a positive and significant effect on employee turnover intention. The R-square calculation result is 0.225, which means that the job satisfaction and work environment variables collectively explain 25.5% of the variance in turnover intention among PT. XYZ employees. The remaining variance can be explained by other variables beyond the scope of this study.

Early seral forests regenerating after stand-replacing disturbance events can provide important habitat for populations of wild bees, an important group of pollinating insects. However, variability in the abundance and diversity of wild bee communities across different types of early seral forests is poorly understood, and can inform pollinator conservation efforts and sustainable forest management practices. In this study, we compared wild bee assemblages from early seral forests regenerating from three widespread stand-replacing disturbances across a gradient in stand ages in the Klamath Ecoregion of southwest Oregon using blue vane traps. Here, we present occurrence data for each bee specimen observed in the study, including voucher specimens deposited to the Oregon State Arthropod Collection.

In the Context of Widespread Global Citizenship Education -- Clearly Understand Its Dilemma and Solutions
Authors: Yu Ruixi
Published: December 2024

In the 21st century, the world environment requires people to view global issues and crises from a global perspective. This places demands on global education, and global citizenship education is an educational concept advocated by the United Nations Educational, Scientific and Cultural Organization (UNESCO) to adapt to the requirements of the international environment. Under such advocacy, global citizenship education has been widely promoted and disseminated among countries worldwide. However, obvious obstacles and problems have emerged simultaneously in this process. Therefore, the research topic of this article pertains to the understanding of global citizenship identity and global citizenship education, as well as the necessity of its global promotion. It also involves analyzing the difficulties and problems encountered during its implementation and proposing appropriate solutions. The author has proposed solutions such as localizing the core concept of GCE and integrating it into local university curricula, and elaborated on the feasibility and necessity of doing so.
