Authors: Bit-Lian Yee , Sharuddin Rashidah Binti , Hasim Salina Binti Mohd , Shariff Siti Fatimah Md , Yusof Y. Surahaya Mohd , Salim Aniszahura Abu
Published: February 2025

Moral distress, a pervasive challenge in critical care nursing, arises when external constraints prevent nurses from acting in alignment with their ethical convictions. This phenomenon significantly impacts nurses, patients, and healthcare systems, leading to burnout, ethical disengagement, and systemic inefficiencies. This review synthesizes existing literature to explore the evolution, causes, and consequences of moral distress in critical care settings. Key contributors include systemic factors like resource limitations and rigid organizational policies, interpersonal conflicts, and high-stakes clinical challenges such as end-of-life care and futile treatments. The review emphasizes the profound implications of moral distress, highlighting its role in reduced job satisfaction, compromised patient care, and increased turnover. Strategies to mitigate moral distress include fostering supportive ethical climates, implementing ethics education, and promoting self-care and resilience-building practices. Additionally, it underscores the need for systemic reforms, longitudinal research, and the integration of technology in ethical decision-making. Addressing moral distress is vital for enhancing nurse well-being, improving patient outcomes, and sustaining healthcare systems.

Construction of three-dimensional cartilage autograft and evaluation of the superiority of interperichondrial implantation
Authors: Avşar Yakup , Aygıt Ahmet Cemal
Published: February 2025

Aims: This study aimed to develop a three-dimensional (3D) cartilage autograft using diced cartilage and fibrin tissue glue and to compare the outcomes of interperichondrial implantation versus subcutaneous implantation in terms of graft viability, biomechanical properties, and histopathological characteristics.
Methods: Eleven albino rabbits underwent auricular cartilage harvesting, with a 3 × 2 cm segment dissected bilaterally. After dicing, the cartilage fragments were combined with fibrin tissue glue and molded into two 3D dorsal nasal grafts. One graft was implanted into the interperichondrial pocket of the right ear, and the other was placed subcutaneously in the right dorsal region. Two control sites were created: subcutaneous fibrin-only implantation on the left dorsal region and an empty interperichondrial pocket on the left ear. The rabbits were sacrificed at eight weeks, and the grafts were evaluated macroscopically, physically, and histopathologically.
Results: Two animals were excluded due to graft loss from flap necrosis. In the remaining rabbits, the interperichondrial group exhibited superior shape retention, less volume loss, and higher elasticity compared to the subcutaneous group (p < 0.05). Histopathological assessment showed significantly greater chondrocyte viability (p < 0.05) and new cartilage formation (p < 0.05) in the interperichondrial group, coupled with lower vascularization (p < 0.05) and reduced fibrosis (p < 0.05). By contrast, the subcutaneous group exhibited prominent vascularization, dense fibrous encapsulation, and more pronounced shape and volume loss. No significant intergroup differences were observed for fibrin residue or ossification (p > 0.05). The control grafts (fibrin-only and empty interperichondrial sites) demonstrated no cartilage formation.
Conclusion: Diced cartilage grafts combined with fibrin tissue glue are better supported in the interperichondrial environment than in the subcutaneous tissue. Interperichondrial implantation not only preserves graft shape and volume but also enhances chondrocyte viability and cartilage regeneration, emphasizing its potential as a clinically valuable strategy in reconstructive cartilage grafting.

This article presents an in-depth analysis of the polarity properties of polar and nonpolar covalent compounds found in various family medicinal plants, and explores their potential applications in health and the food industry. Covalent compounds, which are formed through the shared use of electron pairs between atoms, play an important role in determining the chemical and physical properties of a substance. This study used solubility and filter paper testing methods to identify the polarity of compounds in plant samples such as orange, lemon, tomato, spinach, and chili, which were found to be polar, and cinnamon, ginger, turmeric, galangal, and kencur, which showed nonpolar properties. These results suggest that polar compounds have the potential to be applied in products that require interaction with water, such as herbal drinks, while nonpolar compounds are more suitable for use in oil-based formulations, such as ointments or essential oils. A deeper understanding of the polarity characteristics of these compounds not only broadens scientific insights into medicinal plants, but also opens up opportunities for the development of innovative products in the pharmaceutical and food fields

Abstract. Air pollution, particularly from particulate matter (PM), poses serious public health and environmental risks, especially in urban areas. To address this, accurate source apportionment (SA) of PM is essential for effective air quality management. Traditional SA approaches often rely on offline data collection, limiting timely responses to pollution events. SA applied on data from online techniques, especially with high temporal resolution is advantageous over offline techniques, enabling the study of the diurnal variability of emission sources and also the study of specific events. Recent technological advancements now enable real-time SA, allowing continuous, detailed analysis of pollution sources. This study presents the first application of the ACSM-Xact-Aethalometer (AXA) setup combined with SoFi RT software for real-time source apportionment (RT-SA) of PM in Athens, Greece. The AXA setup integrates chemical, elemental, and black carbon data streams, covering a broad spectrum of PM components and capturing a comprehensive representation of PM sources in an urban environment. The results demonstrate that traffic-related emissions are the largest contributors to PM, with significant contributions from secondary species such as sulfate, nitrate, ammonium, and secondary organic aerosols, which together accounted for approximately 57 % of the PM mass. Primary sources such as biomass burning and cooking contributed around 10 % each, with natural sources like dust and sea salt comprising the remainder. The SoFi RT software is employed for continuous SA, offering automated analysis of PM sources in near real-time (minutes after the measurements). Our findings demonstrate that this setup effectively identifies major pollution sources. This work underscores the AXA system's potential for advancing urban air quality monitoring and informs targeted interventions to reduce PM pollution.

Published: February 2025

Abstract. Understanding water transport and circulation in coastal seas and transitional environments is among the key topics of oceanographic and climate research, as well as recognizing the role of the land-sea interface. The Danube Delta represents a natural laboratory for river-sea hydrodynamic modelling due to its complex morphology and being subjected to several natural and anthropogenic stressors. In this work, we present the results of the SHYFEM finite element hydrodynamic model application to the whole river-sea continuum of the Danube Delta region. The model was run for several years to characterize: 1) the water discharge distribution among the river branches, 2) the general hydrodynamic characteristics of the coastal region of freshwater influence, 3) the transport time scale of the Razelm Sinoie Lagoon System, and 4) the processes driving the river-lagoon-sea interconnections. The unique numerical description of the transport and mixing in the different water bodies of the Delta (river branches, channels, lagoons and coastal sea) may be used to provide the scientific basis to assess the impact of human activities and to design efficient management choices. Indeed, we used the modelling framework to evaluate the effect of reconnection (restoration) measures in the Razelm Sinoie Lagoon System designed to improve hydrological connectivity.
CoSWAT-WQ v1.0: a high-resolution community global SWAT+ water quality model
Authors: Nkwasa Albert , James Chawanda Celray , Theresa Nakkazi Maria , van Griensven Ann
Published: February 2025

Abstract. Quantifying the global extent of anthropogenic impacts on freshwater quality remains challenging due to limited monitoring data, especially in low and middle-income regions. To address this gap and improve our understanding of surface water quality, we introduce CoSWAT-WQ, a large-scale water quality model developed to simulate river water quality constituents of Total Nitrogen (TN) and Total Phosphorus (TP), across global and regional freshwater systems. CoSWAT-WQ, an adaptation of the Soil and Water Assessment Tool (SWAT), is run at a global scale, providing high-resolution simulations that capture spatial and daily temporal dynamics of riverine nutrient loads. Here, we describe the model's inputs, setup structure, processes, and evaluate its performance by comparing model outputs to in-situ water quality observations and other global nutrient models. CoSWAT-WQ achieves comparable ranges of river nutrient loads in comparison to other global nutrient models. Additionally, a normalized root mean square error (nRMSE) < 1 was achieved with in-situ observations at more than 80 % of the gauging stations for TN and TP concentrations. However, there was a general weak underestimation of observed concentrations and variability as seen with low Kling–Gupta efficiency (KGE) values for selected stations. Despite its limitations, the model enables the simulation of river TN and TP constituents at a global scale while keeping local relevance. CoSWAT-WQ’s modular setup allows coupling with sectoral models addressing lake systems, agricultural runoff, and aquatic biodiversity, thereby broadening its applicability for cross-sectoral assessments. The model outputs offer valuable data that can inform ecological risk assessments, human health evaluations, and policy decisions on global freshwater quality management.

Published: February 2025

Abstract. Systematic monitoring and assessment of vegetation dynamics and changes are essential for informing environmental management and conservation strategies. Addressing this need, our study introduces a pioneering procedure to generate a database of vegetation indices that provides semi-monthly updates from 1981 to the present at a 1.1 km spatial resolution, focusing on the Iberian Peninsula and the Balearic Islands. This database enables near-real-time monitoring and analysis of vegetation anomalies. The methodology developed combines harmonized historical satellite imagery from AVHRR, MODIS, and VIIRS sensors. The database's performance was assessed, demonstrating highly accurate and consistent harmonization of NDVI data over time. Notably, the database is adept at identifying temporal variability and trends in vegetation activity and detecting disturbances caused by fire and other phenomena. This work not only advances our understanding of vegetation dynamics in the region but also serves as a crucial tool for policymakers, environmental managers, and agricultural stakeholders. By providing near-real-time updates and using indices to monitor vegetation anomalies, the data allows for comparisons across seasons and vegetation types. The database, which includes the NDVI and kNDVI vegetation indices as well as their standardized versions, SNDVI and SkNDVI, is accessible via https://doi.org/10.20350/digitalCSIC/16201 (Franquesa et al., 2024).
Global consumption-based deforestation carbon emissions and regional hotspots: 2001–2015
Authors: Tang Dongmei , Yao Yuanzhi , Li Xia
Published: February 2025

Abstract. The consumption-based carbon emissions dataset for deforestation is essential for developing effective emission reduction policies by offering an alternative perspective. Although previous studies have provided national-scale data on deforestation emission footprints, the global scale data with detailed and continuous spatial information is still lacking. Here, we created a global consumption-based carbon emissions gridded dataset for deforestation at a 1 km resolution for 2001–2015, integrating spatial data on road networks, deforestation, and forest carbon fluxes with country-level statistics on global trade. Our dataset reveals that trade-related carbon emissions induced by deforestation were 25.3 Gt CO2e, constituting 31.0 % of global carbon emissions due to deforestation. Additionally, the top 20 countries are responsible for most of the consumption-based carbon emissions which contribute to over 80 % of the global total. While high-income countries are responsible for 68.8 % of hidden deforestation emissions in trade, the ones in lower-income counties are rising due to the notable consumption in higher-income areas. This new dataset help addresses the previous data gap in consumption-based global deforestation emissions, aiding the formulation of consumer-side emission reduction strategies and expanding the approaches for mitigating carbon emissions due to anthropogenic activities. Datasets are available at https://doi.org//10.6084/m9.figshare.28091879 (Tang et al., 2024).

Published: February 2025

Abstract. The Marysvale volcanic field in southwestern Utah hosts three large-volume gravity slides: the Sevier (SGS), the Markagunt (MGS), and the Black Mountains (BGS). The gravity slides are composed of lahar deposits, lava flows, and ash-flow tuffs erupted from former stratovolcanoes and other vents during the Oligocene and Miocene. The ash-flow tuffs are prime targets for dating to constrain the age of the gravity slides because some ash-flow tuffs are deformed within the slides, whereas others are undeformed and cap the slides. Furthermore, the gravity slides produced pseudotachylyte during slide motion, a direct indicator for the timing of each slide. This work provides new 40Ar/39Ar dates for several ash-flow tuffs and pseudotachylyte for the SGS, along with U/Pb zircon dates for one deformed tuff and alluvium near the slide plane. Results show that the slide was emplaced at 25.25 ± 0.05 Ma and was immediately followed by the eruption of the Antimony Tuff at 25.19 ± 0.02 Ma. The model presented here suggests that the intrusion of magma related to the Antimony Tuff acted as a triggering mechanism for the slide and that slide movement itself led to decompression melting and eruption of the Antimony Tuff. This sequence of events occurred on a geologically rapid timescale and may have been virtually instantaneous.
CropSuite v1.0 – a comprehensive open-source crop suitability model considering climate variability for climate impact assessment
Authors: Zabel Florian , Knüttel Matthias , Poschlod Benjamin
Published: February 2025

Abstract. Increasing demand for agricultural land resources and changing climate conditions require strategic land-use planning and the development of adaptation strategies. Therefore, information about the suitability of agricultural land is a prerequisite. Current suitability approaches often focus on single crops, can only be applied regionally, and usually neglect the impact of climate variability on crop suitability. Here, we introduce CropSuite, a new, comprehensive, and easy-to-use crop suitability model that allows us to overcome these shortcomings. It provides a graphical user interface (GUI) and a wide range of pre- and postprocessing options, including a tool for data analysis, which allows users to easily apply the model and analyze the results. Further, it includes a spatial downscaling approach to climate data, which enables crop suitability analysis at very high spatial resolution. CropSuite uses a fuzzy-logic approach and is based on the assumption of Liebig's law of the minimum. An expandable number of environmental and socioeconomic factors that affect crop suitability can be flexibly integrated into CropSuite by determining membership functions. CropSuite allows for the consideration of irrigated and rainfed agricultural systems, vernalization requirements for winter crops, lethal temperature thresholds, photoperiodic sensitivity, and several other limitations for crop growth. The model endogenously calculates and outputs climate, soil, and crop suitability, the optimal sowing and harvest dates, the potential for multiple cropping, the (most-)limiting factor(s), and the recurrence rate of potential crop failure according to the inter-annual climate variability. In this study, we apply CropSuite to 48 crops at a spatial resolution of 30 arcsec (1 km at the Equator) for Africa. Thereby, we consider regionally important staple and cash crops that are usually understudied, such as coffee, cassava, banana, oil palm, cocoa, cowpea, groundnuts, mango, millet, papaya, rubber, sesame, sorghum, sugar cane, tobacco, and yam. We find that the consideration of climate variability when calculating crop suitability makes a significant difference to suitable areas but also affects optimal sowing dates and multiple cropping potentials. The most vulnerable regions for climate variability are identified in Somalia, Kenya, Ethiopia, South Africa, and the Maghreb countries. The results provide valuable crop-specific information that can be further used for climate impact assessments, adaptation, and land-use planning at the global, regional, or local scale. CropSuite is provided as open-source code and could be of interest for model developers, scientists, and a wide range of potential users and stakeholders, such as farmers, companies, governmental organizations (GOs), and non-governmental organizations (NGOs).
Flexible manipulator trajectory tracking based on an improved adaptive particle swarm optimization algorithm with fuzzy PD control
Authors: Sun Weiwei , Jin Yubin , Dai Kun , Guo Zhongyuan , Ma Fei
Published: February 2025

Abstract. Trajectory planning for flexible manipulators is a critical area of research in robotics. A trajectory tracking controller can enhance the accuracy of the manipulator's path and reduce vibrations. However, current flexible manipulators remain largely in the research phase, with many studies revealing issues such as poor accuracy in dynamic modeling, weak tracking performance in controller design, and insufficient vibration suppression capabilities. To address these challenges and improve the trajectory tracking performance of the manipulator, this paper focused on vibration suppression and trajectory planning for a two-link flexible manipulator and proposed a novel control method that integrates a modified adaptive particle swarm optimization algorithm (MAPSO) with fuzzy proportional–derivative (PD) control to achieve effective trajectory tracking. Firstly, the dynamic equations of the two-link flexible manipulator system were derived using the assumed modal method in conjunction with Lagrangian dynamics. Next, a 3-5-3 hybrid polynomial algorithm based on MAPSO was proposed to optimize the trajectory of the manipulator. Simulation results demonstrated that the optimization algorithm significantly enhances efficiency. Specifically, the number of iterations required for the two joints was reduced by 33 % and 54 %, respectively, when compared to the original algorithm. Additionally, this optimization led to a total reduction in running time of 0.03 s. Subsequently, the MAPSO algorithm was utilized to enhance the fuzzy PD controller based on the previously obtained optimal trajectory, leading to the development of a trajectory tracking controller known as MAPSO-FuzzyPD. Simulation results indicated that the proposed algorithm significantly reduced the maximum starting torque for both joints. Specifically, the maximum starting torque of joint 1 was decreased by 61.3 % and 40.3 % when compared to PD control and fuzzy PD control, respectively. Additionally, the maximum starting torque of joint 2 was reduced by 57.9 % and 42.1 % in comparison to the same control methods. Finally, an experimental platform for the flexible manipulator was established, and the experimental results further validated the effectiveness and feasibility of the algorithm proposed in this paper concerning joint trajectory tracking.
Meta-programming with Maple and C
Authors: Kotsireas Ilias
Published: February 2025

We show how to use Maple as a source language for meta-programming, with C being the target language, for experimenting with and solving combinatorial problems. We will illustrate this approach with toy problems, as well as with more substantial projects. In the latter case, familiarity with basic concepts from compiler theory may be advantageous to the reader. One advantage of using Maple as a source language for meta-programming for combinatorial problems, lies in the fact that we can use Maple’s symbolic engine to perform complicated manipulations of mathematical objects fast and reliably and therefore produce easily bug-free code in the target language. Another advantage is that we can use Maple’s underlying powerful programming language, including functions, procedures and modules, to create a meta-program that is easy to debug, modify and maintain. The target language can be changed to any other language the user is acquainted and/or at ease with, for example Java, Perl, Python, MPI and so forth. The approach we advocate can be used for both educational and research purposes.

This study aimed to investigate the effects of 60-second static stretching on the neuromuscular control strategies of lower limb muscles during a squat jump (SJ), with a specific focus on changes in muscle synergy patterns, muscle weightings, and temporal activation characteristics. The muscles targeted for stretching included the quadriceps, hamstrings, and triceps surae. Electromyography (EMG) was used to assess the activity of the biceps femoris (BFL), triceps surae(TS), rectus femoris (RF), vastus lateralis (VL), and vastus medialis (VM). Twenty-five active males completed experiments under both a static stretching condition (SS) and a non-stretching condition (NS). Electromyography and non-negative matrix factorization (NMF) were employed to extract muscle synergy and the muscle weightings along with temporal activation characteristics were subsequently analyzed. The results revealed two distinct muscle synergy patterns in both the SS and NS. 60-second static stretching had no significant impact on the number of muscle synergy patterns during the squat jump. However, it significantly altered the contribution and temporal activation characteristics of individual muscles. Notably, post-stretching muscle activation levels were lower during the early phase of the jump, necessitating compensatory activation in the later phase to maintain performance. Additionally, jump heights were significantly lower in the stretched compared to the non-stretched condition.These findings suggest that while 60 seconds of static stretching before explosive movements may impair neuromuscular efficiency, ensuring proper and balanced static stretching for all muscle groups could help mitigate over-reliance on individual muscles.

Systemic inflammation in chronic obstructive pulmonary disease (COPD) contributes to multimorbidity and a diminished quality of life. Probiotics, through the gut-lung axis, have shown potential to mitigate systemic inflammation; however, their specific role in COPD-related inflammation remains unclear. The aim of this study was to evaluate the efficacy of probiotics in reducing serum interleukin-6 (IL-6) levels by enhancing butyric acid production in a murine model of COPD. An in vivo experimental study with a post-test-only control group design was conducted using 30 C57BL/6 mice randomized into five groups: non-COPD healthy control, untreated COPD, COPD treated with bronchodilator, COPD treated with probiotics, and COPD treated with a combination of bronchodilator and probiotics. COPD was induced by six weeks of cigarette smoke exposure, followed by six weeks of treatment while continuing the smoke exposure. Caecal butyric acid and serum IL-6 levels were measured using enzyme-linked immunosorbent assay (ELISA) and gas chromatography, respectively. Caecal butyric acid levels were lowest in untreated COPD mice (1.2±0.28 mmol/L) and significantly increased with probiotic administration (6.6±4.43 mmol/L, p=0.010), exceeding levels observed in healthy controls (3.9±2.05 mmol/L). Serum IL-6 levels were highest in COPD-induced mice (19.4±6.71 pg/mL) and significantly reduced with administration of probiotics (13.5±0.43 pg/mL, p=0.035), approaching levels of healthy controls (13.0±2.24 pg/mL, p=0.847). A negative correlation was observed between butyric acid and serum IL-6 levels (r=-0.420; p=0.021), suggesting that higher butyric acid levels were associated with reduced systemic inflammation. These findings demonstrated that probiotics, via their metabolite butyric acid, effectively reduced systemic inflammation in a COPD mouse model, highlighting their potential as a therapeutic approach for managing COPD-related inflammation.
