Authors: Li Wei , Liu Shiling , Yang Zhaohui 
Published: February 2025

Abstract
The northwest region is one of the regions with the richest solar energy resources and superior natural conditions in China. It is an ideal region for developing comprehensive solar thermal energy systems. In this paper, first of all, taking advantage of the characteristics of solar energy resource endowment in the northwest region, a comprehensive solar thermal energy system is designed for the northwest region. Secondly, a proposed integrated layout and design method for solar thermal integrated energy systems addresses the issue of deep coupling between capacity allocation and operational planning that exists in traditional integrated energy systems. Next, an integrated layout and design method for solar thermal integrated energy systems is proposed, which solves the problem of inaccurate matching between capacity allocation and operational planning in traditional integrated energy systems. Finally, in order to verify the superiority of the proposed solar thermal integrated energy system and its integrated layout and design method, a typical park in the northwest region of China is taken as an example for a case study and compared with the “following heat load” operation mode of traditional integrated energy systems, verifying that the proposed solar thermal integrated energy system and its integrated layout and design method are in good condition. The experimental simulation results show that the comprehensive layout and design method of the solar thermal integrated energy system in the northwest region proposed in this paper can effectively reduce system operating expenses, significantly reduce carbon emissions, realize the comprehensive utilization of electricity and heat, and effectively alleviate the energy shortage in remote areas.

Authors: Ju Pengpeng , Wang Yong , Meng Qingfei 
Published: February 2025

Abstract
Offshore large-module PV foundations are prone to vibration under the action of pulsating wind, causing structural damage. In this paper, based on the Davenport wind spectrum, the wind speed and wind pressure time history are simulated by the harmonic superposition method. The structure is modeled by SACS software, and the modal and wind vibration time history analysis is carried out. The results show that the wind vibration response is dominated by the overall motion, and the wind vibration coefficient based on the base shear is about 1.52. The wind vibration response is dominated by the fluctuating wind direction, but it causes vibration in both the orthogonal and vertical directions. The vertical vibration of the topside is obvious, and the whole produces torsional vibration. The stress level of the upper chord, the umbrella-shaped support, the web member connected to it, and the root area of the pile foundation are relatively high.

Abstract
To analyze the dynamic characteristics of diesel engine camshafts and the factors affecting camshaft speed fluctuations, a multi-body dynamic model for gear transmission analysis is established. We analyze and consider the calculation results of spring preload, spring stiffness, cam profile, crankshaft timing gear speed fluctuation, gear meshing clearance, accessory load, and part rotational inertia on the fluctuation of camshaft angular velocity. The results show that gear clearance has a significant impact on camshaft speed fluctuation, while other factors have a relatively small impact on camshaft speed fluctuation. As verified through bench tests, the test results are consistent with the simulation.
Experimental research on the cold storage and release performance of air conditioning systems using phase change tubes
Authors: Jia Rongrong , Qi Hong 
Published: February 2025

Abstract
A phase-change cold storage air conditioning system incorporates phase-change rods to facilitate thermal energy storage and subsequent release for temperature regulation. Water and PCM systems can be utilized as thermal storage media to accumulate cold energy during the nocturnal period, thereby facilitating the release of this stored cold energy throughout daylight hours to accomplish the intended cooling objective. This work presents an innovative approach involving phase change materials, which investigates the methodologies for load balancing through peak shaving and valley filling to achieve equilibrium in power distribution. The phase-change material with a phase-change temperature of 6 ℃ is filled into an aluminium rod with a diameter of 50mm. 950 PCM aluminium rods are put vertically in the space of about 4.3 m3 tank. The duration for the system to achieve the cooling of the storage compartment, along with its resultant impact on investigations into the differential effects of various cooling storage and thermal release conditions on the water-based and Phase-Change Composite (PCCS) systems, were conducted.

Published: February 2025

Abstract
The self-circulating evaporative cooling technology, which utilizes latent heat, is developed to address the thermal dissipation challenges in wind power generation. To meet miniaturization requirements, the condenser adopts the plate-fin heat exchange without fans. This study presents a method for calculating the airflow friction. Six different specifications of heat exchangers were fabricated. Measurements of air inlet and outlet wind velocities were conducted in the FD-2010-008 wind tunnel. Based on the experimental data, a new adaptive correlation of friction resistance coefficient is proposed, with the prediction error between −13.2% and +14%. The new formula is applicable to air inlet velocities ranging from 4 m/s to 14m/s, with depths of 40 mm to 110 mm, fin heights of 2 to 12.5 mm, and fin spacing of 2 mm to 3 mm.

Published: February 2025

Abstract
This study examines the impact of individual cell performance variations on the overall efficiency of fuel cell systems. Using MATLAB and COMSOL software, we developed a one-dimensional model of a fuel cell stack and a three-dimensional model of a single cell for integrated simulation. The objective is to improve the uniformity of the fuel cell stack by optimizing flow channel dimensions. The research investigates performance disparities among individual cells resulting from uneven fluid distribution and evaluates the effect of flow rate on cell performance. By optimizing the flow channel dimensions, we mitigated performance deficiencies caused by inadequate gas supply. The results demonstrate a 5.59% improvement in the performance of cells with previously insufficient gas supply following optimization. Although increasing the inlet flow rate can enhance performance, the rate of improvement diminishes with higher flow rates. Post-optimization, the performance disparity between cells with the maximum and minimum inlet flow rates decreased by 7.7%, resulting in a 67.3% enhancement in the overall consistency of the stack.
Verilog-based logical design of CubeSat ACS based in fuzzy inference systems focused on trapezoidal membership functions
Authors: López-Balcázar C. A. , Hernández Jorge , Ramírez-López F. , García-Balcázar G. G. 
Published: February 2025

Abstract
Nowadays, fuzzy inference systems are popular tools to implement control systems with relative development ease and speed. In particular, within CubeSat development, it is crucial to implement systems subject to severe design restrictions imposed by the CubeSat Standard, like size, weight and power consumption, among others. For attitude control in CubeSats, one option is to implement fuzzy inference systems of the Sugeno type. However, control algorithms based in fuzzy logic principles are, as many others, established in a sequential order, following specific steps, and not requiring further repetitive tasks. In this sense, they are more suitable to be implemented in logic circuitry than in microcontrollers or microprocessors. Thus, in this work we present the logical design of an attitude control subsystem for CubeSats which is developed in Verilog® hardware description language, which is then validated through simulation. As this is an ongoing research, the presented system only implements triangular/trapezoidal membership functions.

Abstract
Scaffolds that emulate the architecture of human bone, combined with strong mechanical stability and biocompatibility, are vital for promoting effective bone tissue regeneration. However, most existing bone-mimetic scaffolds fall short in reproducing the intricate hierarchical structure of human bone, which restricts their practical application. This study introduces a novel strategy that combines rotational three-dimensional (3D) printing technology and sponge replication technique to fabricate bone-mimetic scaffolds based on composite materials comprising copper-substituted diopside and biphasic calcium phosphate. The scaffolds closely mimic the structure of human bone, featuring both cancellous and cortical bone with Haversian canals. Additionally, the scaffolds exhibit high porosity and transport capacity, while exhibiting compressive strength that is on par with human bone under both axial and lateral loads. Moreover, they demonstrate good biocompatibility and the potential to induce and support osteogenesis and angiogenesis. The scaffolds produced here present a pathway to remediating particularly large bone defects. Given their close resemblance to human bone structure and function, these scaffolds may be well-suited for developing in vitro bone disease models for pharmaceutical testing and various biomedical applications.
Modelling the effects of climate policy on firewood collection and women’s welfare in developing countries
Authors: Aggarwal Raavi 
Published: February 2025

Abstract
Climate policies such as carbon taxes for emissions reduction could be detrimental to social welfare in developing countries. High energy prices could induce substitution towards traditional solid fuels such as fuelwood for cooking. Given fuelwood is primarily collected by women in low- and middle-income countries, climate policies may particularly affect women’s welfare. This article reviews the empirical evidence on climate policies, energy use and women’s well-being. Further, I develop a theoretical framework to characterise the potential effects of climate policy and complementary social policies on women’s welfare. The theoretical results show provision of clean cooking technologies and improved biomass cook-stoves, when complementary to fuel taxes, could improve women’s welfare and confer health and climate benefits in developing countries. The predictions of the theoretical framework are validated in the empirical literature.
The iGains4Gains model guides irrigation water conservation and allocation to enhance nexus gains across water, food, carbon emissions, and nature

Published: February 2025

Abstract
This paper introduces and applies iGain4Gains, an Excel-based model, to reveal how changes to water conservation and allocation, and irrigation technology, can produce four nexus gains. These gains are; reduced aggregate water consumption, sustained crop production, lower carbon emissions, and enhanced water availability for nature. We developed the model with limited data and hypothetical future scenarios from the Amman–Zarqa basin in Jordan. Given its significant irrigation and urban water demands and difficult decisions regarding future water allocation and nexus choices, this basin is a highly appropriate case study. The paper’s primary aim is to demonstrate the iGains4Gains nexus model rather than to build an accurate hydrological model of the basin’s water resources. The model addresses two critical questions regarding increased irrigation efficiency. First, can irrigation efficiency and other factors, such as irrigated area, be applied to achieve real water savings while maintaining crop production, ensuring greenhouse gas emission reductions, and ‘freeing’ water for nature? Second, with the insight that water conservation is a distributive/allocative act, we ask who between four paracommoners (the proprietor irrigation system, neighbouring irrigation systems, society, and nature) benefits hydrologically from changes in irrigation efficiency? Recognising nexus gains are not always linear, positive and predictable, the model reveals that achieving all four gains simultaneously is difficult, likely leading to trade-offs such as water consumption rebounds or increased carbon emissions. Demonstrated by its use at a workshop in Jordan in February 2024, iGains4Gains can be used by students, scientists and decision-makers, to explore and understand nexus trade-offs connected to changes in irrigation management. The paper concludes with recommendations for governing water and irrigated agriculture in basins where large volumes of water are withdrawn and depleted by irrigation.
An Invisible Archive
Authors: I. Córdova Hidalgo Amalia 
Published: February 2025

Abstract
This chapter raises the question of preservation of Indigenous film and video collections and archives, as a responsibility to Indigenous cultural memory. The chapter expands the concept of the archives beyond the physical works themselves, looking at these collections as repositories of Indigenous knowledge that constitute invaluable sources for future research and productions. These collections are in a state of precarity and are dispersed in variety of formats and collections, ranging from informal and individual to institutional and inaccessible. Issues of return, cataloging, processing, and preservation are discussed through interactions with select works and collections, underscoring the need to consider community access or shared stewardship in collection development and preservation.

Abstract
The use of pesticides has become a worldwide concern, and Brazil is one of the countries that release the most pesticides and is affected by them. These chemical substances, when in contact with the human body, can cause health problems such as nephrotoxicity, neurodegeneration, and even cancer. This study investigates how direct and indirect pesticide exposure interferes with acetylcholinesterase (AChE) and hematological parameters. This cross-sectional study was conducted in Sergipe, Brazil, and included 378 participants. The impact of pesticides on AChE and hematological parameters in individuals exposed to these agents was evaluated. Triazine (TZ) and Organochlorine (OC) classes combination generated the lowest AChE. A lower mean for AChE for individuals directly exposed to pesticides (p &lt; 0.05) was observed. Men and younger individuals tended to have lower levels of AChE, as did individuals who declared themselves black or yellow or did not declare any ethnicity. As for hematological alterations, micronuclei (MN) were detected in 12.2% of farmers and 8.7% of families and neighborhoods. We found that AChE values tended to increase with the number of platelets and red blood cells (RBC). Still, we did not detect any other relationships between AChE and the type of exposure with hematological parameters. These findings contribute to evaluating the impact of pesticide exposure on human health. Thus, it allows us to infer that individuals directly exposed to pesticides tend to have lower levels of AChE, demonstrating the need to monitor these clinical parameters in individuals exposed to these agents and seek to identify the profile of this population.

Abstract
Previously, we described the divergent evolution of probiotics in the gut, which potentially compromises their health-promoting effects. Here, we employed a spatiotemporal multiomic approach to explore the distribution and evolutionary trends of the probiotic Lactiplantibacillus plantarum HNU082 (Lp082) in specific-pathogen-free (SPF) and Monocolonized (Mono) mouse models. Initially, after establishing the inherent differences in the gut microbiota between the small and large intestines, we observed that the small intestine served as the main site for Lp082 survival and colonization. Subsequently, we discovered that the small intestine was the sole site where Lp082 exhibited divergent evolution. Moreover, our research indicated that Lp082 had a more substantial impact on the small-intestinal microbiota than on the large-intestinal microbiota. Consequently, we observed a significantly greater number of closely associated species coevolving with Lp082 in the small intestine than in the large intestine. This suggests that Lp082 faced higher selective pressures within the small intestine, potentially leading to the emergence of a greater number of mutants. Our findings will contribute to the differentiated application of probiotics, enhancing their beneficial effects, and offer insights into the targeted domestication of probiotic strains.

Published: February 2025

Abstract

Aim
The current study aimed to establish a phenotypic and genotypic characterization record of a novel lytic bacteriophage (phage) against multidrug-resistant (MDR) Escherichia coli (E. coli) infections.

Methods and results
Phenotypic characterization of the isolated phage included the assessment of phage morphology, host range, stability, and antibiofilm activity. The isolated phage vB_EcoM_ECO78 demonstrated high lytic activity against MDR E. coli and E. coli serotypes O78:K80:H12 and O26:H11. Additionally, it showed a marked antibiofilm activity and high physical stability at a wide range of temperatures and pH. Genotypic investigations identified a double-stranded DNA genome of 165 912 base pairs (bp) spanning 258 open reading frames (ORFs), out of which 149 ORFs were identified and annotated. In vivo analysis further confirmed the therapeutic potential of vB_EcoM_ECO78 which effectively increased the survival of mice infected with MDR E. coli.

Conclusion
The isolated phage vB_EcoM_ECO78 exhibits considerable stability and antibiofilm activity against MDR E. coli isolates, supported by notable environmental fitness and in vivo antibacterial capability.

Published: February 2025

Background
Older patients with chronic heart failure (CHF) are prone to insomnia. Studies have shown that insomnia affects the onset of cognitive frailty and is also strongly associated with depressive symptoms and social support. However, information on how these factors interact to influence cognitive frailty remains underexplored.

Objective
Our aim in this study was to explore the multiple mediating roles of depressive symptoms and social support in the relationship between insomnia and cognitive frailty.

Methods
We recruited 300 hospitalized older patients with CHF to participate in this study. The participants completed the Athens Insomnia Scale, Geriatric Depression Scale, Montreal Cognitive Assessment, FRAIL Scale, and Social Support Rating Scale. The mediation hypothesis was tested using a multiple mediation model and bootstrapping method.

Results
In this study, 44% of the patients experienced insomnia, and 51.3% were in a state of cognitive frailty. Our main findings suggest that insomnia has an indirect effect on cognitive frailty through 2 pathways: the multiple mediating effects of depressive symptoms and social support, and a single mediating effect of depressive symptoms. The direct effect of insomnia on cognitive frailty is also significant.

Conclusions
Older patients with CHF who experience insomnia tend to have more severe depressive symptoms, cognitive frailty, and poor social support. Thus, interventions to recognize insomnia early, improve depressive symptoms, and provide social support may reduce cognitive frailty in older patients with CHF. Longitudinal studies are necessary to further refine our findings and address the limitations of the current study.
