Authors: Silva José , Serrano Luís , Martins Pedro , Ferreira Hugo , Váz Paulo , Guerra Emanuel
Published: January 2025

This research presents the design, construction, and experimental evaluation of a novel box-type solar oven optimized for enhanced thermal efficiency and heat retention, developed to address the challenges of sustainable cooking in temperate climates. The solar oven, measuring 120 cm × 60 cm × 45 cm, incorporates strategically designed rock wool insulation and 5 kg of steel plates as thermal mass, along with a double-glazed glass cover tilted at an experimentally optimized angle of 15° relative to the horizontal plane. Extensive experimental testing was conducted in Viseu, Portugal (40° N latitude) under varying meteorological conditions, including solar irradiance levels ranging from 400 to 900 W/m2 and wind speeds of up to 3 m/s. The results demonstrated that the oven consistently achieved internal temperatures exceeding 160 °C, with a peak temperature of 180 °C, maintaining cooking capability even during periods of intermittent cloud cover. Quantitative analysis showed that the thermal efficiency of the oven reached a peak of 38%, representing a 25–30% improvement over conventional designs. The incorporation of thermal mass reduced temperature fluctuations by up to 40%, and the enhanced insulation reduced conductive heat loss by approximately 30%. Cooking tests validated the oven’s practical effectiveness, with the successful preparation of various foods including rice (90 min), cake (120 min), vegetables (60 min), and bread (110 min). This study provides comprehensive performance data under different meteorological conditions, including detailed temperature profiles, heating rates, and thermal efficiency measurements. By addressing key limitations of prior models, particularly the challenge of temperature stability during variable solar conditions, the proposed solar oven offers a cost-effective, efficient solution that can be adapted for use in diverse climates and regions, with particular relevance to areas seeking sustainable alternatives to traditional cooking methods.

Authors: Iqdymat Ahmed , Stamatescu Grigore
Published: January 2025

This study investigates the integration of reinforcement learning (RL) with optimal control to enhance precision and energy efficiency in industrial robotic manipulation. A novel framework is proposed, combining Deep Deterministic Policy Gradient (DDPG) with a Linear Quadratic Regulator (LQR) controller, specifically applied to the ABB IRB120, a six-degree-of-freedom (6-DOF) industrial manipulator, for pick-and-place tasks in warehouse automation. The methodology employs an actor–critic RL architecture with a 27-dimensional state input and a 6-dimensional joint action output. The RL agent was trained using MATLAB’s Reinforcement Learning Toolbox and integrated with ABB’s RobotStudio simulation environment via TCP/IP communication. LQR controllers were incorporated to optimize joint-space trajectory tracking, minimizing energy consumption while ensuring precise control. The novelty of this research lies in its synergistic combination of RL and LQR control, addressing energy efficiency and precision simultaneously—an area that has seen limited exploration in industrial robotics. Experimental validation across 100 diverse scenarios confirmed the framework’s effectiveness, achieving a mean positioning accuracy of 2.14 mm (a 28% improvement over traditional methods), a 92.5% success rate in pick-and-place tasks, and a 22.7% reduction in energy consumption. The system demonstrated stable convergence after 458 episodes and maintained a mean joint angle error of 4.30°, validating its robustness and efficiency. These findings highlight the potential of RL for broader industrial applications. The demonstrated accuracy and success rate suggest its applicability to complex tasks such as electronic component assembly, multi-step manufacturing, delicate material handling, precision coordination, and quality inspection tasks like automated visual inspection, surface defect detection, and dimensional verification. Successful implementation in such contexts requires addressing challenges including task complexity, computational efficiency, and adaptability to process variability, alongside ensuring safety, reliability, and seamless system integration. This research builds upon existing advancements in warehouse automation, inverse kinematics, and energy-efficient robotics, contributing to the development of adaptive and sustainable control strategies for industrial manipulators in automated environments.

Authors: Feng Yini , Chen Rongning , Xu Guobao
Published: January 2025

In recent years, with rapid economic development, the importance of environmental governance has gradually been overlooked. The increasing pollution caused by rural sewage discharge has posed a significant threat to the local ecological environment. In this context, this paper treats the local governments, village enterprises, and farmers as the game subjects, integrating them with prisoner’s dilemma theory to construct a tripartite game model. By analyzing the equilibrium points and stability of the model, as well as the effects of the parameters in the dynamic equations, this paper reveals the evolution of strategic choices made by different participants. The results indicate that the optimal strategy for local governments is strict regulation, and village enterprises tend to adopt purification measures, while farmers weigh the costs and benefits and exhibit a negative attitude toward participating in governance. Finally, from a practical perspective, this paper offers suggestions for improving rural ecological environmental protection by engaging local governments, village enterprises, and farmers, aiming to promote the sustainable development of the ecological environment.

Published: January 2025

In recent years, the strategic development and utilization of historical and cultural resources in historic urban areas to foster advanced cultural industries has become a pivotal approach for promoting urban renewal. However, there are significant differences between the urban development models of Western countries and the unique context of China, rendering it challenging to directly apply Western theories to explain China’s urban development. As one of the leading cities in both cultural industry growth and urban renewal in China, Guangzhou offers a valuable case for examining how cultural industries can effectively empower urban renewal. This paper aims to explore and analyze the mechanisms through which cultural industry development influences urban renewal in China, using Guangzhou as a case to illustrate the dynamic interactions between cultural industries and urban transformation. Furthermore, it proposes a contextualized model and strategy for the role of cultural industries in driving urban renewal, thereby providing evidence-based insights and practical recommendations for enhancing the contribution of cultural industries to urban development. This study suggests that Guangzhou should further advance this goal by strengthening policy support, promoting the digital cultural industry, strengthening infrastructure for cultural industry spaces, and developing distinctive cultural industry projects, thus facilitating sustainable and high-quality urban development.
The Spatial Distribution of Fallow Land and Its Ecological Effects in the Agro-Pastoral Ecotone of Northern China
Authors: Cao Haoran , Meng Mei
Published: January 2025

Fallowing is a widely adopted approach for land restoration and ecological protection in the agro-pastoral ecotone of northern China. However, research on the ecological impacts of fallowing in this ecologically fragile region is still limited. With the implementation of fallow policies, it is essential to update the delineation of fallow areas to reflect current practices and ecological considerations. This study developed an index system to assess ecological vulnerability and subsequently delineated fallow areas based on urgency. The ecological effect of fallowing was evaluated using the Ecological Index. Our results show that priority and secondary priority fallow areas are predominantly located in the northern and central regions of the northern agro-pastoral ecotone, covering approximately 33.46 × 104 km2 by 2023. During the implementation of the fallow policy from 2015 to 2019, the Ecological Index of each county increased, indicating improved environmental quality. However, from 2019 to 2023, the ecological status declined in all three counties, with minor changes in Guyuan County and Fengzhen City. Notably, the ecological degradation rate was faster in Huan County without the second round of fallow. These results indicate that fallowing has a beneficial effect on various aspects of the ecological environment in arid and semi-arid regions, including soil and water conservation, water network density, and vegetation coverage. Furthermore, this improvement demonstrates a sustained effect over time.
A Real Estate Price Index Forecasting Scheme Based on Online News Sentiment Analysis
Authors: Xu Tao , Zhao Yingying , Yu Jie
Published: January 2025

The real estate price index serves as a crucial indicator reflecting the operational status of the real estate market in China. However, it often lags until mid-next month, hindering stakeholders from grasping market trends in real time. Moreover, the real estate market has an extremely complex operating mechanism, which makes it difficult to accurately assess the impact of various policy and economic factors on the real estate price index. Therefore, we hope, from the perspective of data science, to explore the emotional fluctuations of the public towards the real estate market and to reveal the dynamic relationship between the real estate price index and online news sentiment. Leveraging massive online news data, we propose a forecasting scheme for the real estate price index that abandons complex policy and economic data dependence and is solely based on common and easily obtainable online news data. This scheme involves crawling historical online real estate news data in China, employing a BERT-based sentiment analysis model to identify news sentiment, and subsequently aggregating the monthly Real Estate Sentiment (RES) index for Chinese cities. Furthermore, we construct a Vector Autoregression (VAR) model using the historical RES index and housing price index to forecast future housing price indices. Extensive empirical research has been conducted in Beijing, Shanghai, Guangzhou, and Shenzhen, China, to explore the dynamic interaction between the RES index and both the new housing price index and the second-hand housing price index. Experimental results showcase the unique features of the proposed RES index in various cities and demonstrate the effectiveness and utility of our proposed forecasting scheme for the real estate price index.

Published: January 2025

Integrated Sensing and Communication (ISAC) systems have emerged as a key component for Sixth Generation (6G) networks, enhancing resource efficiency and enabling diverse applications. Currently, ISAC systems have been recognized as a leading trend for future standardization, i.e., International Mobile Telecommunications (IMT)-2030. As in the previous IMT-2020 standardization, the emphasis has been on developing a methodology for assessing network conditions, with one of the crucial approaches incorporating system-level simulations. However, within this framework, there has been a notable absence of proposed abstractions for the physical layer of ISAC systems, which are valuable for system-level simulators. The physical abstraction process helps reduce computational simulation costs, enabling efficient and rapid evaluation of system conditions. Therefore, this paper aims to fill this gap by outlining the key aspects and metrics recommended for a physical layer abstraction in sensing applications within ISAC frameworks. Applying physical abstraction in the context of target localization and detection algorithms may enable an initial understanding and evaluation of ISAC system performance. These algorithms are proposed as an example of simulating the sensing functionalities to be abstracted, which are based on a stochastic geometric channel model. Orthogonal Frequency Division Multiplexing (OFDM) symbols play a crucial role in target position estimation. The findings show that doubling OFDM symbols improves the detection probability by 3 dB in terms of Signal to Noise Ratio (SNR). Finally, the proposed Physical Layer Abstraction (PLA) method produces performance metrics as figures and lookup tables tailored for system-level simulators.

Published: January 2025

Background: Equine herpesvirus type 1 (EHV1) is a ubiquitous viral pathogen infecting the equine population worldwide. EHV1 infection causes respiratory illness, abortion, neonatal foal mortality, and myeloencephalopathy. The currently available modified live EHV1 vaccines have safety and efficacy limitations. The two mutant EHV1 viruses (vToH-DMV (∆IR6/gE) and vToH-QMV (∆IR6/UL43/gE/UL56)), generated by the deletion of genes responsible for virulence (gE and IR6) and immunosuppression (uL43 and uL56), have been previously characterized by our group and found to generate good immune responses. The present study aimed to determine the safety and protective efficacy of the above mutants against a virulent EHV1 challenge in a murine model. Methods: BALB/c mice were intranasally immunized with a live vToH-QMV or vToH-DMV vaccine. Intranasal booster immunization was given at 14 days post-vaccination (dpv). Both mutants induced an optimal level of EHV1-specific humoral and cell-mediated immune responses, as determined by virus neutralization assay, ELISA, and immunophenotyping. At 35 dpv, the mice were intranasally challenged with wild-type EHV1 (vRaj strain). Results: Amongst the two mutants, vToH-QMV induced a better immune response than the vToH-DMV vaccine. Furthermore, vToH-QMV provided good protection in mice against the virulent challenge. It specifically exhibited less severe clinical disease in terms of clinical signs, body weight reduction, and gross and histopathological lung lesions accompanied by early virus clearance. Conclusions: These studies are suggestive of vToH-QMV EHV1 being a potential vaccine candidate against EHV1 infection, which needs to be finally tested in the main host, i.e., horses.
Shaping the Space: A Role for the Hippocampus in Mental Imagery Formation
Authors: Blomkvist Andrea
Published: January 2025

Mental imagery is claimed to underlie a host of abilities, such as episodic memory, working memory, and decision-making. A popular view holds that mental imagery relies on the perceptual system and that it can be said to be ‘vision in reverse’. Whereas vision exploits the bottom-up neural pathways of the visual system, mental imagery exploits the top-down neural pathways. But the contribution of some other neural areas remains overlooked. In this article, I explore important contributions of the hippocampus, a neural area traditionally associated with episodic memory, to mental imagery formation. I highlight evidence which supports the view that the hippocampus contributes to the spatial model used for mental imagery and argue that we can distinguish different hippocampal circuits which contribute to different kinds of imagery, such as object imagery, scene imagery, and imagery with a temporal aspect. This has significant upshots for mental imagery research, as it opens a new avenue for further research into the role of the hippocampus in a variety of imagery tasks.
Assessment of Pluvial Flood Mitigation Ecosystem Service in a Riverside City Using the Integrated Valuation of Ecosystem Services and Tradeoffs Model for Ecological Corridor Mapping
Authors: Castillo-Acosta Yajaira , Cárdenas-Pillco Berly , Chanove-Manrique Andrea
Published: January 2025

Riverside cities are vulnerable to pluvial flooding due to multiple factors, such as landscape fragmentation caused by land-use changes, which weakens the ecosystem service of pluvial flood mitigation. This ecosystem service is essential because it reduces the impact of this climatic event through water infiltration into the soil. The metropolitan area of Arequipa, Peru, a riverside city, is currently fragmented by accelerated population growth, which has filled the river buffer zones and agricultural areas with concrete, resulting in a fragile flood control ecosystem service. This research assesses the pluvial flood mitigation ecosystem service in the metropolitan area of Arequipa using the InVEST software 3.12.1 to map an ecological corridor. The results show low runoff control in urban environments but significant retention in agricultural and non-agricultural vegetation areas. Zero-runoff patches were identified as ecological sources, and a resistance surface map and least-cost path model were created, yielding a 57 km ecological corridor connecting 18 ecological sources across 12 of Arequipa’s 19 metropolitan districts. This study highlights the importance of integrating ecosystem services into urban planning to support green infrastructure initiatives, which contribute to sustainable and resilient cities by mitigating fragmentation and enhancing natural flood defenses.

Published: January 2025

Sorbents based on polyacrylonitrile fiber, containing ferrocyanides of transition metals and manganese oxides (CoMn-PAN and FeMn-PAN) or iron(III) hydroxide (CoFe-PAN) in their structure were obtained, as confirmed by the results of X-ray diffraction and energy-dispersive analyses. The selectivity of the obtained sorbents was investigated, along with their ability to sorb Cs, Ba (as an analog of Ra), P, and Be from various natural media, including river water and seawater with varying salinity of 18.2 and 33.8 ‰. The data show that the sorbents are universal for the recovery of artificial 137Cs and natural radionuclides from the natural environments, including complex salt composition (seawater). Researching the obtained sorbents during marine expeditions confirmed the efficiency of the obtained materials based on transition metal ferrocyanides and manganese oxides (CoMn-PAN and FeMn-PAN) for the sorption of 137Cs, 7Be, 210Pb, 210Po, 226Ra, 228Ra, and 234Th. Additionally, the sorbent based on transition metal ferrocyanides and iron(III) hydroxide (CoFe-PAN) was effective for the sorption of 137Cs, 7Be, 32P, 33P, 210Pb, 210Po, and 234Th. Based on the obtained results, methods for comprehensively determining artificial 137Cs and natural radionuclides using these sorbents were developed.

Published: January 2025

Complex geological, gas geochemical and hydro meteorological studies were conducted to investigate the methane fields present in the bottom sediments and seawater of the Red River and Phu Khanh sedimentary basins. We demonstrate that the system of tectonic faults that formed the sedimentary basins of the Red River and the Phu Khanh (the eastern shelf and slope of Vietnam) created the necessary conditions for the generation and migration of endogenous methane into the bottom sediments and seawater. It is shown that dissolved methane in seawater can be transported by marine currents, which in turn can be influenced by seasonal and irregular synoptic processes. The research shows that part of the dissolved methane contained in the waters above the Ken Bau gas field can be transported to the south by the coastal Vietnamese current, which adapts to the conditions of the winter northeast monsoon. It is concluded that there could be at least two deep sources of hydrocarbon gas emissions in the Phu Khanh basin. The impact of Typhoon Nakri on the transport of dissolved methane in the water column of the Phu Khanh sedimentary basin has been investigated. The typhoon could create favorable hydrodynamic conditions for the movement of dissolved gases from oil and gas deposits near the coasts of the islands of Kalimantan and Palawan to the Phu Khanh basin. A possible route for this transfer has been identified.

Objectives: Liver ischemia-reperfusion (I/R) is the director’s origin of damages in various clinical situations, especially surgery and transplantation. Inflammatory damages are critical because of the chronicity of I/R injuries (I/RI). The hepatoprotective and antiinflammatory properties of silibinin have been reported in different studies. This study aimed to investigate the effect of Silibinin on the expression of the pannexin-1 (Panx1) gene during hepatic I/R. Materials and Methods: In this case-control animal study, a total of 32 male Wistar rats (n=8 in each) were surveyed. The animals were randomly assigned into four equal groups as follows: Group 1 (Control): the rats underwent a midline laparotomy with normal saline injection; Group 2 (SILI): the rats received Silibinin (50 mg/kg) after laparotomy; Group 3 (I/R): the rats underwent I/R surgery and received normal saline; and Group 4 (I/R+SILI): the rats received silibinin before ischemia and directly following reperfusion. Blood and liver tissue samples were taken after three hours of reperfusion aftermath 1-hour ischemia to evaluate histological changes, gene expression, and serum markers of hepatic injury. Results: While the serum aspartate aminotransferase (AST) and alanine aminotransferase (ALT) levels in the I/R group significantly increased compared to the control group (P<0.001), they significantly decreased in the SILI+I/R group (P<0.001). Silibinin ameliorated inflammatory impairments of liver tissue, such as neutrophil and macrophage infiltration and activation, hepatocyte degeneration and vacuolation, hepatic vascular endothelial damage, and sinusoid proliferation in the I/R group. The expression of the Panx1 mRNA during I/R significantly increased compared to the control group (P<0.001), but silibinin reduced the expression (P<0.001). Conclusions: We witnessed that silibinin reduced liver tissue damages during hepatic I/R. Correcting the expression of the Panx1 gene during I/R is probably one of the mechanisms of anti-inflammatory effects of silibinin.

Published: January 2025

Background: Radiotherapy-induced hypothyroidism (HT) seems to be more frequent in breast cancer (BC) patients receiving radiotherapy to the supraclavicular field because part of the thyroid gland is included in the field. Thus, this study aimed to evaluate radiation-induced HT in patients with BC by assessing thyroid function before and 6 months after radiotherapy. Materials and Methods: In total, 27 patients undergoing three-dimensional conformal radiotherapy for BC were enrolled in this study. Thyroid-stimulating hormone (TSH), thyroxine, and triiodothyronine (T3), as well as parathyroid hormone (PTH), were measured before, on the last day of radiotherapy, and 6 months after radiotherapy. In addition, dose-volume parameters of the thyroid gland, including the volume of the thyroid gland receiving 20 Gy, 30 Gy, 40 Gy, and 50 Gy, as well as the mean dose to the thyroid, were derived from dose-volume histograms. Statistical comparisons were performed utilizing SPSS 16.0 software. The normal distribution of the data was investigated using the Shapiro-Wilk test. A paired t-test was used to compare thyroid and parathyroid function tests before and after radiation therapy (RT), and P values≤0.05 were considered statistically significant. Results: No statistically significant difference was found between thyroid and parathyroid function tests before and 6 months after the completion of radiotherapy (P>0.05). There was a significant difference only in the T3 level before and the last day of radiotherapy (P=0.027). The mean (standard deviation) thyroid dose was 15.0 Gy (6.8), and the mean (SD) value of V20-30-40-50 was 30.3% (14.8), 24.9% (14.8), 18.9% (14.2), and 7.5% (10.7), respectively. Conclusion: The findings revealed that thyroid and PTH levels did not significantly change before and 6 months after BC radiotherapy. This finding is important for both patients and healthcare providers, highlighting that HT is unlikely to be a critical factor in the management and prognosis of BC following RT.

Published: January 2025

Tuberculosis (TB) is a significant health concern worldwide and its incidence is increasing in developed countries. Extra-pulmonary TB, especially in the gastrointestinal tract, is often a difficult and delayed diagnosis because it can mimic metastasis or infection. Diagnostic problems can delay appropriate treatment and play a role in TB transmission. We report a case of extra-pulmonary TB that has affected the gastrointestinal tract of a 34-year-old patient residing in Iran. The patient was admitted to the surgical department 6 months before the visit with a complaint of vague abdominal pain and was discharged without any specific diagnosis. The patient presented with pulmonary symptoms during the visit and was hospitalized. All laboratory tests were negative for TB in the patient. Finally, a laparoscopic biopsy confirmed peritoneal TB infection. This case report shows the risk of misdiagnosis in patients and consequently delay in starting appropriate treatment, which may lead to the death of the patient.

The Tribal are the community which over the years socially isolated, economically and educationally deprived, politically exploited and detached class of development of modern society. In present context the need to more attention to focus for achieve of their holistic development. The term tribe today has different scholastic dimensions and reflections in Indian politics. The meaning of word tribe has assumed different connotations and definition in different countries as their culture. Even today the world is astonishing because even after the studies and research regarding tribal community over the years the term ‘tribe’ failed to get a universal definition till day.

Sorghum (Sorghum bicolor (L.) Moench) is a major food crop in West Africa. In Mali, sorghum grains are used for human consumption (Tô, couscous, porridge, etc.) while the stems and leaves are used as livestock feed and building materials. However, it must be recognized that production faces many constraints such as low productivity and poor digestibility of local varieties, etc. The aim of our study is to contribute to improving human and animal nutrition through the development of sorghum hybrids combining high grain and straw yield potential. Thus, 44 F1 hybrids including 15 parents and 1 Fadda hybrid control were evaluated in three environments: Sotuba, Samanko and Kolombada for their grain and straw yield performance. The experimental design used is an Alpha Lattice with three replicates per environment. Hybrid heterosis effects of -22.66% to +254.06% for grain yield versus 26.25% to 255.97% for straw yield were observed. Thirty-five hybrids were found to be superior to control cultivars and parental pure lines in terms of productivity and stability.
