Enhancing Data Query Flexibility with GraphQL: Implementation and Best Practices
Authors: Nagaraju Thallapally
Published: February 2025

Modern web and mobile applications require efficient and flexible data retrieval to optimize performance and improve user experience. Clients using traditional REST APIs experience inefficiencies through receiving excessive data beyond their requirements or needing multiple calls to obtain all necessary information. Such limitations produce greater network latency and data transfer charges while making client-side logic more complex as it manages unnecessary or absent data.Facebook developed GraphQL as a query language solution, which enables clients to request precise data sets through one single request. REST APIs offer static endpoints that deliver fixed data structures, while GraphQL presents a dynamic schema that enables clients to request multiple resources in one query. This method decreases API request numbers while simultaneously enhancing efficiency through payload size reduction and response time shortening. This paper analyzes GraphQL's design and implementation while evaluating how its performance and scalability advantages stack up against those of RESTful APIs. This study analyzes practical applications that demonstrate GraphQL's ability to improve data fetching efficiency while outlining best practices for building scalable GraphQL APIs. This paper provides a detailed exploration of schema design and query optimization along with caching strategies and security considerations while examining how GraphQL integrates with current backend services. We also identify problems like complex queries, performance bottlenecks, and schema changes while providing ways to resolve these problems.

Published: February 2025

El propósito del presente estudio es contribuir a optimizar el uso de la materia prima en el proceso de aserrío, por lo que se evaluaron 11 acciones correctivas tendientes a reducir la variación en el grosor de la madera aserrada de Pinus spp en tres aserraderos de Durango. Cada acción fue evaluada mediante muestras de 10 tablas con grueso nominal de 22.23 mm (7/8”); para conocer la variación del grueso en la madera, se utilizó el método de medición de puntos múltiples, comparando el efecto de cada acción con una muestra testigo de tablas aserradas sin implementar ninguna acción. Los resultados mostraron que dos de las once acciones evaluadas mostraron una marcada reducción en la variación del corte de la madera aserrada desde 49 hasta 64%, lo cual se consiguió mediante la disminución de la velocidad de alimentación del asierre y el ajuste de las guías de la sierra.

Authors: Gerashchenko M. V
Published: February 2025

Methods. In the course of study, the following methods were used: a systematic approach – to identify the components of the agricultural sector’s resilience under martial law; the method of abstraction – to identify the essential features of resilience and sustainability of the national economy; the method of analysis and synthesis – to determine the interrelationships of the components' impact in the overall context of the agricultural sector's resilience; modelling – to develop a theoretical model of the agricultural sector's resilience; induction and deduction – to formulate the study's conclusions. Results. The article identifies the essential features of sustainability and resilience of the national economy. The relationship between the components of resilience and sustainable development of the agricultural sector under martial law is characterised. It is substantiated that in order to ensure sustainable development of the agricultural sector during martial law, it is important to simultaneously take into account its resilience (operational adaptability) and sustainability (environmental, economic and social balance). The main components of the sustainability of the agricultural sector of Ukraine are highlighted: economic, social, environmental, international support, logistics and infrastructure, and technological innovations. It is established that ensuring the resilience of the agricultural sector requires an integrated interaction of these components, since under martial law there is a decrease in cultivated areas, damage to infrastructure, disruptions in logistics and social threats. It is emphasised that the priority of ensuring the economic and environmental resilience of the agricultural sector of Ukraine is necessary not only for its survival under martial law, but also for creating the basis for post-war recovery. It is generalised that the implementation of the circular economy concept will allow combining economic sustainability with the environmental priorities of the agricultural sector, creating conditions for sustainable recovery after the war and strengthening international competitiveness. Novelty. The article proposes a theoretical model of resilience of Ukrainian agricultural sector in the form of a pyramid, the structure of which includes economic, social, environmental, technological and managerial components. The formation of a theoretical model of resilience in the form of a pyramid is an effective approach that emphasises the hierarchical nature of the interaction of key components, each of which has a practical implementation that meets modern challenges. Practical value. The results of the study can be used by institutions in the process of developing measures that promote the stability of the agricultural sector, improve logistics, infrastructure and technological innovation, which in turn supports the effective recovery and functioning of the industry under martial law and its sustainable development after the end of the war.

Introduction

HyTan, a new chestnut tannin extracted from chestnut wood via hydrodynamic cavitation at low temperature in water only, is an effective biostimulant for the nursery production of high-quality grapevine planting material.

Methods

Experiments were carried out in Sicily with HyTan aqueous extracts obtained at different temperatures (45, 60 and 75°C) and dosage (pure extract or diluted with water) on the above-ground and below-ground characteristics of cv. Zibibbo cuttings grafted on rootstock 1103 Paulsen.

Results and discussion

HyTan tannin extracted at low temperature (45°C) favored the growth of both thinner root fraction and total above-ground plant as well as the leaf chlorophyll content. These findings open the route to the widespread use in agriculture of this newly extracted chestnut tannin rich in ellagic acid, nonhydrolyzed ellagitannins (castalagin and vescalagin) and gallic acid.

Authors: Acharya Bibek , Sharma Vivek
Published: February 2025

Analyzing soil water dynamics is crucial for the advancement of sustainable agriculture, encompassing crop growth management, soil health preservation, and the strategic use of resources. This study assessed the impact of conventional and sod-based crop rotations on water dynamics within the Suwannee River Basin’s unique karst and sandy soil environment from 2019-2022. The study was conducted on a 16-hectare center pivot irrigated field, featuring two conventional crop rotations: one comprising maize (Zea mays) and peanut (Arachis hypogaea), and another including maize, carrot (Daucus carota), and peanut. In addition, two sod-based rotations were evaluated: one involving two years of bahiagrass (Paspalum notatum) followed by maize and peanut, and another comprising two years of bahiagrass succeeded by maize, carrot, and peanut. The results indicated that maize maintained consistent crop water productivity (WPC-ETc) at 2.6 kg m-3 across rotations, while WPC-ETc for peanuts ranged from 1.5 kg m-3 for conventional rotation and 1.1 kg m-3 for sod-based. The cumulative crop evapotranspiration (ETc) for maize throughout the years was on an average 477 mm (Standard Deviation (SD) = 44 mm), while peanuts showed an average cumulative ETc of 354 mm (SD = 39 mm). Carrots and bahiagrass recorded cumulative ETc values in the range of 225-259 mm and 1611 mm (over two years), respectively. Deep percolation accounted for 31% of total water input, which emphasizes the need for strategic water management in porous soils. Additionally, sod-based rotations increased field capacity by 32%, soil organic carbon (SOC) by 31% in the top 15 cm, and soil aggregate stability by 101%, enhancing soil structure and moisture conservation. This study highlights sod-based rotations as effective for soil and water conservation, offering practical strategies for water-efficient agriculture in similar ecosystems.
Case Report: Hybrid closed-loop insulin pump can significantly improve awareness of hypoglycemia
Authors: Zadáková Eliška , Horová Eva
Published: February 2025

Impaired awareness of hypoglycemia remains an issue even in the era of modern technologies, as patients with type 1 diabetes (T1DM) face stricter requirements for glycemic targets. The evaluation of hypoglycemia awareness can be accomplished using questionnaires (Clarke and Gold scores) in combination with clinical appearance and sensor data. A 45-year-old man with T1DM was referred to our clinic in July 2019 due to impaired hypoglycemia awareness and repeated severe hypoglycemic episodes resulting in unconsciousness. At that time, he was driving both a car and a motorcycle. Despite good compliance, increased target values and implementation of continuous glucose monitoring (CGM) with alarms, prolonged hypoglycemias were not eliminated. Therefore, the patient was referred for pancreatic islet transplantation, but he decided not to undergo. In May 2021, his driving license was suspended, which eventually led him to accept treatment with a hybrid closed-loop insulin pump (AID). Shortly after initiation, he achieved satisfactory glycemic control, reduced time spent in hypoglycemia, and had no severe hypoglycemic episodes. According to the questionnaires, the hypoglycemia awareness has improved and his driving license was reinstated. This case study highlights the critical importance of identifying impaired awareness of hypoglycemia, its potential social impacts, and the opportunities for using new technologies to reverse this complication.

Authors: Wu Yitian , Wei Wenhui , Feng Tianxue , Li Wenwen , Wang Xiaoyu , Wu Tao , Zhang Xingshuang
Published: February 2025

Safety of lithium-ion batteries (LIBs) has garnered significant attention. As an essential component of batteries, the separator plays a crucial role in separating the positive and negative electrodes, preventing short circuits, and allowing ion transport. Therefore, it is necessary to develop a high-performance separator that is both thermally stable and capable of rapid Li+ transport. Polyimide (PI) is a material with high thermal stability, but low electrolyte wettability and high interfacial resistance of PI restrict its application in high-performance LIBs batteries. MXene possesses excellent mechanical properties and good electrolyte affinity. PI/MXene nanofiber composite separator. Combines the high thermal stability of PI with the superior electrolyte wettability of MXene. It exhibits a high tensile strength of 19.6 MPa, low bulk resistance (2.5 Ω), and low interfacial resistance (174 Ω), as well as a low electrolyte contact angle of 29°, while retaining the high-temperature resistance and flame retardancy of PI. Batteries assembled with this composite separator demonstrated a specific capacity of 111.0 mAh g−1 and a capacity retention rate of 66% at 2C. In long-term cycling tests of LiFePO₄ half-cells at 1C, after 200 charge-discharge cycles, the PI/MXene battery showed a discharge specific capacity of 126.7 mAh g−1 and a capacity retention rate of 91%. Additionally, the battery operated normally at 120°C. The composite separator, by integrating the high thermal stability of PI with the excellent electrolyte wettability and conductivity of MXene, demonstrates significant advantages in enhancing battery safety and cycling performance. Through this composite structure can provide a more reliable and safe solution for high-performance LIBs.
Generalized hybrid coronary revascularization vs. conventional off-pump coronary artery bypass grafting for multivessel coronary artery disease
Authors: Zhang Shuai , Li Ping , Li Guang , Yan Yunfeng , Sun Tao , Lin Ji , Zhang Chenhao , Liu Shuo , Qu Zheng , You Bin
Published: February 2025

Background

Hybrid coronary revascularization (HCR) has been demonstrated as a safe and effective revascularization strategy in selected patients with multivessel coronary artery disease; however, the inclusion criteria are too strict.

Objectives

This study was conducted to compare in-hospital and midterm outcomes after generalized HCR and off-pump coronary artery bypass (OPCABG) in patients with multivessel coronary artery disease.

Methods

We proposed a generalized idea of HCR. First, the PCI for non-LAD vessels suitable for coronary stents was performed. Then, MICS-CABG for LIMA to the LAD and saphenous to other non-LAD vessels that were not suitable for stents or stenting failed. Propensity score matching was used, and 222 patients (n = 111 in both the generalized HCR and OPCABG groups) were enrolled in the study. The primary endpoint was a major adverse cardiac or cerebrovascular event (MACCE) over midterm follow-up, and the secondary endpoints were in-hospital outcomes.

Results

No signiﬁcant difference was observed in the cumulative rate of MACCE (9.9% vs. 16.2%; HR, 0.567; 95% CL, 0.268–1.201; P = 0.138) between the generalized HCR and OPCABG groups. The residual SYNTAX score was similar between two groups (6.3 ± 5.5 for generalized HCR vs. 6.8 ± 5.3 for OPCABG; P = 0.486). Compared with OPCABG, generalized HCR was associated with a signiﬁcantly lower intra-aortic balloon pump (IABP) implantation rate (2.7% vs. 9.9%; P = 0.027) and shorter postoperative length of stay (6.3 ± 3.2 vs. 7.7 ± 3.0; P = 0.001).

Conclusions

The generalized HCR procedure appears to be safe and efﬁcacious, with outcomes similar to those of standard off-pump CABG and satisfactory completeness of revascularization.

Published: February 2025

Background

Recent developments have made the thrombin generation (TG) test accessible to the clinical laboratory. Therefore, the clinical interpretation of TG parameters has become of increasing interest, and reference values are required. Age and sex have been shown to affect TG parameters, but no consensus has been reached on the subject. We investigated the effect of age and sex on TG parameters to determine the need for age and sex specific reference values for TG.

Methods

TG was measured in 22,014 individuals of the Moli-sani study, a cross-sectional cohort of the general adult Italian population. TG was measured using Calibrated Automated Thrombinography in platelet poor plasma (PPP) using PPP reagent Low and PPP reagent, in the presence and absence of thrombomodulin (TM).

Results

Individuals were grouped into 6 age categories: 35–44 years of age (n = 5,073), 45–54 (n = 6,448), 55–64 (n = 5,516), 65–74 (n = 3,539), 75–84 (n = 1,261), and 85 years of age and older (n = 106). Men and women were distributed evenly in the age categories. Smoking was more common at younger age, whereas cardiovascular diseases, hypertension, hypercholesterolemia, and diabetes were more common at older age (p < 0.001). Lag time and velocity index increased with age, whereas the endogenous thrombin potential (ETP) and time-to-peak decreased. The inhibitory effect of TM was reduced at higher age (p < 0.001). The TG lag time was shorter in women than men at younger age (6%–7% lower in women), and the ETP was lower in women. The activated protein C (APC) pathway was desensitized in women and older individuals.

Conclusion

The TG profile becomes more “procoagulant” at older age, especially in women. The sensitivity of the APC pathway to TM is reduced with increasing age in men and women. Therefore, age and sex appropriate reference values for TG parameters would be of interest for the ongoing clinical implementation of the TG assay.
Using machine learning models for cuffless blood pressure estimation with ballistocardiogram and impedance plethysmogram
Authors: Liu Shing-Hong , Sun Yao , Wu Bo-Yan , Chen Wenxi , Zhu Xin
Published: February 2025

Introduction

Blood pressure (BP) serves as a crucial parameter in the management of three prevalent chronic diseases, hypertension, cardiovascular diseases, and cerebrovascular diseases. However, the conventional sphygmomanometer, utilizing a cuff, is unsuitable for the approach of mobile health (mHealth).

Methods

Cuffless blood pressure measurement, which eliminates the need for a cuff, is considered a promising avenue. This method is based on the relationship between pulse arrival time (PAT) parameters and BP. In this study, pulse transit time (PTT) was derived from ballistocardiograms (BCG) and impedance plethysmograms (IPG) obtained from a weight-fat scale. This study aims to address two challenges using deep learning and machine learning technologies: first, identifying BCG and IPG signals with good quality, and then extracting PTT parameters from them to estimate BP. A stacked model comprising a one-dimensional convolutional neural network (1D CNN) and gated recurrent unit (GRU) was proposed to classify the quality of BCG and IPG signals. Seven parameters, including calibration-based and calibration-free PTT parameters and heart rate (HR), were examined to estimate BP using random forest (RF) and XGBoost models. Seventeen healthy subjects participated in the study, with their BP elevated through exercise. A digital sphygmomanometer was employed to measure BP as reference values. Our methodology was validated using data collected from our custom-made device.

Results

The results demonstrated a signal quality classification accuracy of 0.989. Furthermore, in the five-fold cross-validation, Pearson correlation coefficients of 0.953 ± 0.007 and 0.935 ± 0.007 were achieved for systolic BP (SBP) and diastolic BP (DBP) estimations, respectively. The mean absolute differences (MADs) of XGBoost model were calculated as 3.54 ± 0.34 and 2.57 ± 0.17 mmHg for SBP and DBP, respectively.

Discussion

The proposed method significantly improved the accuracy of cuffless BP measurement, indicating its potential integration into weight-fat scales as an unconstrained device for effective utilization in mHealth applications.

Positive effects on physical well-being were saving time and energy, and brain activation, but exhaustion, increased health risk, and reduced productivity were the negative ones. Besides, teachers experienced positive social well-being, enabling communication among people across the globe, and easier access and transfer of information. Negative social well-being included adverse effects on child-family relationships and reduced face-to-face interaction.

Discussion

To develop healthy habit of technology use, teachers should have information regarding the positive and negative impacts of technology on their physical and social well-being.

In the present research, the relationship between emotional intelligence and burnout was investigated in a sample of Greek special education teachers. The cusp catastrophe model was used for the statistical analysis. Based on the analysis, emotional intelligence was negatively correlated with burnout. Surprisingly, this negative relationship was reversed when the increase in the level of emotional intelligence exceeded a certain point. There seems to be a fragile balance between caring and caring too much. Teachers who cannot regulate their sentimentality can be overwhelmed by emotions and become prone to stress and burnout. The cusp catastrophe model managed to describe that phenomenon more satisfactorily than the linear and quadratic models tested. According to the other analysis results, factors such as mental resilience and self-efficacy had a negative relationship with burnout. Practical implications such as emotional intelligence training and self-focus wellbeing were discussed.

Introduction

In southern China, four species of the Taxus genus are distributed, and identifying their suitable habitats plays an important role in species conservation.

Methods

This study used the MaxEnt model to simulate and predict the potential suitable habitat distribution for these four species. The prediction model utilized 257 occurrence points from the four yew species, along with historical climate and topographic data, and incorporated the distribution of nature reserves in China. The model’s accuracy was validated using the Area Under the Receiver Operating Characteristic Curve (AUC) to compare the effect of different function models on prediction accuracy.

Results

The results showed that the AUC values for all four yew species exceeded 0.9, indicating a high level of reliability in the model predictions. The high-suitability area for Taxus wallichiana var. chinensis is 13,943.62 km2, with nature reserves covering 7.49% of this area; Taxus wallichiana var. mairei has a high-suitability area of 11,950.97 km2, with a coverage rate of 2.44%; Taxus wallichiana has a high-suitability area of 9,784.43 km2, with a coverage rate of 10.52%; and Taxus yunnanensis has a high-suitability area of 7,226.57 km2, with a coverage rate of 6.47%. The high-suitability areas for T. wallichiana var. chinensis are concentrated in the Qinling, Wuyi, and Hengduan mountain ranges, while T. wallichiana var. mairei has a broader distribution, primarily in the Wuyi, Qinling, Hengduan, and southeastern Himalayas. The distributions of T. wallichiana and T. yunnanensis are concentrated in the Hengduan Mountains and southeastern Himalayas.

Discussion

The study suggests expanding the network of protected areas, constructing ecological corridors, and introducing cultivation efforts to enhance population stability within high-suitability zones. For T. wallichiana var. mairei and T. wallichiana var. chinensis, it is recommended to attempt more reintroduction efforts, while for T. wallichiana and T. yunnanensis, habitat protection should be prioritized. The establishment of additional natural protected areas and the construction of ecological corridors linking these protected areas are important ways to strengthen the conservation of yew species.

Understanding tree growth in relation to environmental conditions is essential, particularly in the context of climate change, where rising temperatures, frequent droughts, and disturbances threaten forest health and productivity. This study uses high-resolution data from four intensively monitored Picea abies stands in Austria (2010–2020), with dendrometers recording hourly stem increments on 10 trees per site, allowing for detailed analysis of growth responses to environmental changes. For this purpose we tested different generalized additive mixed models (GAMs) using environmental data collected on site. The best model consisted of combinations of soil moisture (SM) and soil temperature (ST) data. Furthermore we analyzed how the relationships established differ for three different times during the growing season. We found that high SM consistently had a positive effect on tree growth, wheras the effect of ST varied depending on the timing. Our findings underscore the importance of monitoring soil conditions, particularly for species like Picea abies, which are known for their sensitivity to environmental changes due to their shallow rooting systems and vulnerability to drought.
Inhibition of renin-angiotensin system attenuates type I alveolar epithelial cell necroptosis in rats after hyperbaric hyperoxic exposure

Published: February 2025

Objective

There is evidence showing both necroptosis and activation of renin-angiotensin system (RAS) are involved in the pathogenesis of hyperbaric hyperoxic lung injury (HLI). This study aimed to investigate whether RAS activation can induce lung cell necroptosis and the cell specificity of necroptosis in the lung in case of hyperbaric HLI.

Methods

Male SD rats were randomly assigned into control group (n = 12), HLI group (n = 18), captopril group (n = 18), and valsartan group (n = 18). Rats were pre-treated with intraperitoneal captopril (50 mg/kg) or intragastrical valsartan (30 mg/kg) for 3 days before hyperbaric exposure. Then, animals were exposed to 99.9% oxygen at 250 kPa for 6 h to induce HLI. After hyperbaric exposure, lung function was non-invasively detected, and then animals were sacrificed for the detection of wet to dry ratio of the lung, blood gas and lung inflammatory factors, and lung tissues were collected for double immunofluorescence staining. Statistical analysis was performed with one way analysis of variance.

Results

Either valsartan or captopril pre-treatment could inhibit lung edema, improve blood gas (0 h) and lung function (48 h), and reduce pro-inflammatory factors in the lung. In addition, valsartan or captopril pre-treatment could inhibit AGT1 expression and lung cell necroptosis, and type I alveolar epithelial cells (AECs) were the major cell type experiencing necroptosis after hyperbaric hyperoxic exposure.

Conclusion

Our study indicates inhibition of RAS can suppress the hyperbaric HLI, which may be, at least partially, related to the inhibition of type I AECs necroptosis. Our findings provide new mechanism for the protective effects of RAS inhibition on hyperbaric HLI.

Introduction

Healthcare workers’ well-being is of utmost importance given persistent high rates of burnout, which also affects quality of care. Minority healthcare workers (MHCW) face unique challenges including structural racism and discrimination. There is limited data on interventions addressing the psychological well-being of MHCW. Thus, this systematic review aims to identify interventions specifically designed to support MHCW well-being, and to compare measures of well-being between minority and non-minority healthcare workers.

Methods

We searched multiple electronic databases. Two independent reviewers conducted literature screening and extraction. The Mixed Methods Assessment Tool (MMAT) or Joanna Briggs Institute (JBI) criteria were utilized to assess the methodological quality of studies, based on the study design. Total scores as percentages of criteria met were used to determine overall quality as low (<40%), moderate (40-80%), or high (>80%). For conflicts, consensus was reached through discussion. Meta-analysis was not possible due to heterogeneity of study designs.

Results

A total of 3,816 records were screened and 43 were included in the review. The majority of included studies (76.7%) were of moderate quality. There were no randomized control trials and only one study included a well-being intervention designed specifically for MHCW. Most (67.4%) were quantitative-descriptive studies that compared well-being measures between minority and non-minority identifying healthcare workers. Common themes identified were burnout, job retention, job satisfaction, discrimination, and diversity. There were conflicting results regarding burnout rates in MHCW vs non-minority workers with some studies citing protective resilience and lower burnout while others reported greater burnout due to compounding systemic factors.

Discussion

Our findings illuminate a lack of MHCW-specific well-being programs. The conflicting findings of MHCW well-being do not eliminate the need for supports among this population. Given the distinct experiences of MHCW, the development of policies surrounding diversity and inclusion, mental health services, and cultural competency should be considered. Understanding the barriers faced by MHCW can improve both well-being among the healthcare workforce and patient care.
