Hip Active Range of Motion in Patients with Femoroacetabular Impingement Syndrome
Authors: Stołowski Łukasz , Kerkhoffs Gino , Piontek Tomasz
Published: February 2025

Femoroacetabular impingement syndrome (FAIS) is characterized by hip pain and restricted range of motion (ROM), typically due to structural conflict between the femoral neck and the acetabulum. This study aimed to quantify active ROM limitations in FAIS patients, comparing them with healthy controls to establish normative values, particularly in non-conflicting directions. Methods: A total of 53 FAIS patients scheduled for hip arthroscopy were compared to 49 healthy matched controls. Active ROM was assessed using inertial measurement unit (IMU) sensors, with measurements taken in standing and prone positions. Outcomes included flexion, external rotation, internal rotation, and total rotation ROM, alongside demographic and radiographic data. Gender-based ROM differences were also analyzed. Results: FAIS patients demonstrated significant reductions in flexion, internal rotation, and total rotation ROM in the involved hip, with large effect sizes, while external rotation remained unaffected. ROM in the uninvolved hip was also lower than in controls but showed increased external rotation. Gender differences were observed, with females exhibiting significantly higher internal rotation and, in healthy controls, greater total rotation than males. Conclusions: FAIS patients have significant active ROM restrictions in non-conflicting directions, suggesting broader joint limitations potentially tied to early hip osteoarthritis or capsular and musculoskeletal adaptations. Gender differences highlight the importance of individualized ROM assessment. This study introduces IMU-based ROM evaluation as a promising tool for diagnosing and monitoring FAIS, providing insights into functional impairments that can be used to guide targeted interventions.
Development and Performance Comparison of a 64-Channel Annular Array Probe Excited Simultaneously by Shorted Symmetrically Positioned Elements
Authors: Fukumoto Shintaro , Arakawa Takahiro
Published: February 2025

Ultrasonic testing technology is used to inspect pipe welds in nuclear and thermal power plants. This paper proposes a new method to measure weld defects in thick-walled pipes of about 100 mm using ultrasonic phased array technology. The effectiveness of annular arrays is confirmed by numerical simulations, and element arrangements that enable point focusing and sector scanning are considered. The energy concentration of annular arrays is 7% higher than that of linear arrays and 3% higher than that of matrix arrays. Similarly, the sound pressure ratio of grating lobes is equivalent to that of linear arrays and 20% lower than that of matrix arrays. This array probe is driven by 64 channels by dividing the ring of an 8-element annular array probe in parallel and shorting the elements at symmetrical positions. The effectiveness is examined by measuring specimens with flat-bottom holes and simulated spherical defects. The authors confirmed peaks in the echo intensity of a φ1 mm flat-bottom hole and a φ3 mm pseudo-spherical defect arranged at 5 mm intervals. Comparing the measured results with a conventional linear array transducer, the results from the proposed method show that the number and size of defects can be accurately measured.
Influence of Total Running Experience on Lower Leg Variability: Implications for Control and Performance in Male Athletes
Authors: Steele Jared , Hunter Iain
Published: February 2025

This study investigates the relationship between total running experience, defined as cumulative years of running multiplied by weekly mileage, and variability in lower leg joint kinematics during treadmill running. Twenty-seven male athletes participated, running while kinematic and kinetic data were collected. Linear regression revealed significant negative correlations between total running experience and variability in both knee and ankle joint range of motion (ROM). Specifically, ankle ROM variability (p = 0.001, R2 = 0.35) and knee ROM variability (p = 0.002, R2 = 0.32) were reduced in runners with more experience. A stepwise regression model further identified ankle ROM variability as a significant predictor (p = 0.033), explaining 44.25% of the variance in total running experience. A significant positive correlation between running experience and instantaneous vertical loading rate (IVLR) (p = 0.025, R2 = 0.15) suggests that more experienced runners generate higher load rates. These findings indicate that more experienced runners exhibit more consistent and stable movement patterns, reflecting refined motor control. The results support the hypothesis that greater running experience is associated with reduced variability in movement patterns within a controlled environment, providing insights into the mechanisms that could contribute to enhanced performance and injury prevention.

Published: February 2025

Monitoring and analyzing reservoir landslides are essential for predicting and mitigating geohazards, which are crucial for maintaining sustainability and supporting socio-economic development in reservoir areas. High spatiotemporal resolution is vital for effective reservoir landslide monitoring and analysis. For this purpose, we improved the resolution of the differential interferometric synthetic aperture radar (DInSAR) technique by fusing two-path deformation results from an overlapping Sentinel-1 area. First, we summarized the mathematical ratio relationship between deformation from the two paths. Second, time-series linear interpolation and time-reference difference removal were applied to the two separate deformation results of time-series DInSAR. Third, a ratio algorithm was adopted to fuse the deformation of the two paths into one integrated time-series result. The standard deviations of the deformation before and after fusion were similar, confirming the accuracy of the fusion results and feasibility of the method. From the integrated deformation, we analyzed the hydraulic impact, mechanisms, and physical processes associated with four reservoir landslides in the Three Gorges Reservoir area of China, accounting for rainfall and water-level data. The comprehensive analysis presented herein provides new insights on the hydraulic mechanisms of reservoir landslides and verifies the efficacy of this new integrated method for landslide investigation and monitoring.
Efficient Development and Utilization of Geothermal Energy: An Analysis of the Operational Strategy for Deep-Buried Pipe-Type Energy Piles Considering Seepage Effects
Authors: Liu Xianglin , Tian Yuhan , Liu Yongli , Liu Wen , Zheng Lifei , Li Xiaoqing
Published: February 2025

As a shallow geothermal energy development technology, energy pile contributes to sustainable development. The seepage effect has a positive effect on the heat transfer performance of the energy pile, and the heat transfer efficiency of the energy pile can also be improved by optimizing the operation strategy. Combined with the structural characteristics of the deep-buried energy pile, the heat transfer characteristics of the deep-buried energy pile are analyzed under continuous and intermittent operation conditions, and the effect of seepage on the heat transfer performance is further investigated under the intermittent operation mode. The results show that the long-term operation of the deep-buried energy pile will reduce its heat exchange performance and aggravate the heat accumulation phenomenon inside the pile body, and the intermittent operation can maintain a higher instantaneous heat exchange rate (HER) in the long-term operation compared with the continuous operation. Considering the energy demand, when the intermittent ratio is 5, the average HER of the pile body only decreases by 68.93 W, and the overall energy efficiency of the pile body is improved by 7.7%. Combined with the operating effects of different intermittent ratios, the optimal range of the circulating medium flow rate for deep buried pipe energy piles should be selected from 1.0 m3/h to 1.2 m3/h. Groundwater seepage can weaken the degree of heat accumulation inside the DBP-EP piles and improve the overall heat exchange efficiency of DBP-EP, and combined with the intermittent operation mode will be able to further alleviate the DBP-EP heat buildup. The two factors promote each other and have a positive impact on the piles, positively affecting the soil’s long-term heat exchange.
Driving Effects and Differences of Transportation Carbon Emissions in the Yangtze River Economic Belt
Authors: Guan Haichang , Huang Chengfeng
Published: February 2025

Identifying the driving effects and differentiated characteristics of transportation carbon emissions is crucial for developing targeted and differentiated emission reduction strategies and providing a scientific basis for the Yangtze River Economic Belt. This study adopted a “top-down” approach to account for the transportation carbon emissions of the Yangtze River Economic Belt from 2000 to 2019 and constructed LMDI models and quantile regression models to estimate the driving effects and heterogeneity of influencing factors. The research results indicate the following: (1) The level of economic development is a key driving factor for transportation carbon emissions in the Yangtze River Economic Belt, with a cumulative effect of 160%. Upon inspection, the relationship between economic and transportation carbon emissions conforms to the environmental Kuznets curve. When the per capita transportation production value reaches CNY 7500, there is a “turning point” in transportation carbon emissions. (2) The population size has a driving effect on transportation carbon emissions, but as carbon emissions continue to increase, their marginal effects gradually diminish. (3) The energy structure and transportation structure have a significant inhibitory effect on transportation carbon emissions. The driving effect of the energy structure shows an “N” shape with quantile changes, while the transportation structure gradually converges. (4) Both energy intensity and transportation intensity show inhibitory effects, indicating that innovative energy substitution, optimization of transportation structure, and improvement of organizational efficiency are key ways to achieve carbon reduction in transportation. It is suggested that the Yangtze River Economic Belt should develop differentiated emission reduction paths in different regions, effectively balance economic development and carbon emission control, and promote the green and low-carbon transformation of the transportation system.
Study on Possible Transformation of Leather and Textile Wastes in Carbonised Materials by Pyrolysis Under Different Gas Conditions
Authors: Kowalik-Klimczak Anna , Życki Maciej , Łożyńska Monika , Barszcz Wioletta
Published: February 2025

The possibility of using pyrolysis for the valorisation of leather and textile wastes constituting post-consumer clothes is analysed in this paper. The effect of gas type was investigated on the physico-chemical properties, composition, structure, and formation of the specific surfaces of carbonised materials produced by the pyrolysis process. The differences in the elemental composition of the carbonised materials derived from textile and leather wastes may be due to the specific chemical compositions. Both textile and leather wastes are rich in organic compounds, but their structural and compositional differences significantly influence the element content of carbonised materials. The characteristic feature of carbonised material made from leather waste is a relatively high nitrogen content (approx. 9 wt. %). In turn, in the case of carbonised material made from textile waste, a high carbon content is characteristic (75–80 wt. %). Moreover, G- and D-bands were detected in all the analysed carbonised materials. The presence of these bands confirms the transformation of leather and textile wastes into carbon materials. It was found that maintaining a high degree of order in the structure (calculated as ID/IG ratios based on the D and G peak intensities) of carbonised materials is advantageous to conducting the pyrolysis process on textile materials in N2 and on leather materials in CO2. The carbonised materials produced using these gases are characterised by an ID/IG ratio at a level of 0.05. Pyrolysis carried out in these gases also has a positive effect on the size of the BET surface area. However, it was shown that the carbonised products from textile materials are characterised by a higher BET surface area than that of carbonised products from leather materials regardless of the type of gas used during the pyrolysis process. Furthermore, all the carbonised materials are characterised by a high percentage content of mesopores in the carbon structure. These types of carbon materials have widespread application potential. The presented studies contribute data about the pyrolytic processing of post-consumer clothes (such as leather and textile waste) into carbonised materials to reuse, according to the circular economy model.
Entrepreneurship and Education: An Analysis of the Impact of Compulsory Education Policies in Counties in China
Authors: Xin Xin , Li Pengji , Tang Lichao , Xu Aiyan
Published: February 2025

This paper investigates the influence of expanding free compulsory education on regional entrepreneurial activities, exploring both theoretical and empirical aspects. Our research comprises two main parts. Initially, we employ a novel economic geography model to theoretically assess the effect of extending free compulsory education on regional entrepreneurial endeavors, proposing four hypotheses for further examination. Subsequently, we empirically test these hypotheses using balanced panel data collected from 2528 districts and counties in China spanning from 2000 to 2021. The findings indicate that the expansion of free compulsory education indeed stimulates regional entrepreneurial activity. However, this policy’s impact is influenced by the local industrial structure and the knowledge level of residents. Notably, the effect becomes visible only after the third year of the policy’s enactment, and it demonstrates a certain spatial spillover. Our conclusions remain consistent even after accounting for various endogenous factors. Our research has the potential to offer invaluable countermeasures for other developing countries, enabling them to advance sustainable development by enhancing their obligations.

Post-mining land in areas where mineral extraction has occurred may constitute a significant portion of the land used for various purposes. Such land serves as soil-forming parent material for developing anthropogenic soils, which sometimes exhibit unfavorable physicochemical properties. The toxicity of the waste generated during lignite mining is due to a number of factors, whose determination permits the identification of its origin for the subsequent design of technologies for the waste reclamation. The purpose of the study, in consistence with sustainable development, is to identify the causes of the toxicity of brown coal waste from the Lengerskoye deposit, in southern Kazakhstan. These studies have provided the results essential for planning remedial actions necessary to improve the well-being of the local population, in accordance with the principles of sustainable development. The studies were performed using single extraction; forms of Al, Fe, and Mn; soil texture; elemental analysis; phytocoenosis analysis; and diffractometric, IR spectroscopic, SEM, route reconnaissance, and comparative statistical methods. A decrease in the biodiversity of plant species was noted, with a gradual increase with distance from the waste storage sites. The most resistant plant species in the vicinity of the waste dump were Cynodon dactylon (L.) Pers and Alhagi pseudalhagi (M. Bieb.) Desv. ex B. Keller & Shap., while Dodartia orientalis (L.) was the only plant species found at the edge of the waste dump. The high toxicity of lignite waste is determined by such factors as low pH values, about 3.0; high content of active forms of aluminum, iron, and manganese (344.0, 0.90, and 20 mg/kg); high electrical conductivity—2835 µS/cm; waste composition poor in nutrients; and climate aridity. It has been observed that a content of exchangeable aluminum above 100 mg/kg resulted in an almost complete lack of vegetation.
Optimizing Order Batching and Picking Problems Considering the Correlation Between Products Under the Scattered Storage Mode
Authors: Deng Yalin , Jiang Wei , Wang Ye , Xu Beiling
Published: February 2025

With the rapid development of e-commerce, the scattered storage mode has been widely applied in B2C distribution centers in which there is a large assortment and quantity of small-sized, time-sensitive orders. Under the scattered storage mode, obtaining high-quality batching results and quickly completing order picking are key to improving the operation efficiency of a distribution center when a large number of orders arrive in a short period. Against this background, a new order batching problem under the scattered storage mode is studied. The feature is to improve the batching quality by considering the correlation between products. The problem is formulated as a 0–1 integer programming model to maximize the sum of pair-to-pair order correlations in all batches. To solve large-scale problems, we first propose two new seed batching algorithms based on the correlation between products. The first one selects the order with the largest number of products as the seed order, and the second one selects the order with the highest correlation as the seed order. Then tabu search (TS) is used to improve these two algorithms. In addition, a new seed batching algorithm for a special situation is proposed, which needs to use the location information of each product to obtain more accurate batching results. Finally, an improved two-stage order picking algorithm is proposed to verify the actual picking effect of the batching results obtained from the different algorithms. The experimental results show that the two seed batching algorithms improved by TS are superior to the existing batching algorithms in batch quality for the general situation, and the second seed batching algorithm improved by TS performs better for large-scale problems. Moreover, the new seed batching algorithm is more efficient and effective.

Published: February 2025

One of the most dangerous geological disaster risks in mountainous areas is granular flow. Slit dams, which might partially block the granular flow and let downstream flow at a slower speed, have been crucial in reducing the geohazards associated with granular flow. In this work, the discrete element method (DEM) was used to explore the effect of the topographic condition of drainage channels, including slope angle and cross-section types, on the interaction between granular flows and slit dams. The interactions dynamic process between the dry granular flows and slit dams with different drainage channel cross-section types has been investigated. And the simulation results demonstrate the significance of taking drainage channel cross-section types into account when designing barriers, particularly slit dams. The flow process, particularly in channels with V-shaped and trapezoidal sections, is characterized by a more rapid movement and larger final accumulation length, potentially resulting in increased impact force on the downstream slit dams. Moreover, the cross-section types and slope angles jointly influence the regulation function and impact force. The dry granular flow in the drainage channel with a V-shaped cross-section leads to a smaller normal impact force and retention efficiency. Taking into account the complexity of construction, retention efficiency, and impact force, it can be concluded that a trapezoid shape is the most appropriate option from an engineering perspective. This research may add to the understanding of the relationship between granular flow and slit dams and help the engineering design of slit dams with scientific evidence.
Corporate Social Responsibility Motive Attributions and Green Behaviors: Moderating Effect of Green Intrinsic Motivation
Authors: Yin Changqin , Tan Jie , Deng Yi
Published: February 2025

Employee green behavior plays an important role in the realization of corporate social responsibility (CSR) goals, and the employee motive attribution of CSR can affect employee green behavior. Therefore, it is important to understand how CSR motive attribution affects their green behavior. However, existing studies rarely establish a direct link between CSR motive attribution and green behavior. Based on the attribution theory, we establish a framework to explore the impact of CSR motive attributions on employees’ green behaviors. To examine our theoretical model and research hypotheses, we conducted an experimental study (Study 1) and a multi-wave survey study (Study 2). The combined results show that (substantive and symbolic) CSR motive attributions positively influence in-role green behavior; however, for extra-role green behavior, substantive CSR motive attribution positively influences it, while symbolic CSR motive attribution negatively influences it. Green intrinsic motivation positively moderates the relationship between CSR motive attributions and in-role green behavior and positively moderates the relationship between substantive CSR motive attribution and extra-role green behavior but negatively moderates the relationship between symbolic CSR motive attribution and extra-role green behavior. This research contributes to the literature related to micro-CSR and provides explanations for the favorable and unfavorable environmental results brought on by substantive and symbolic CSR, respectively.

In the contemporary global context, excessive fossil fuel consumption remains a critical issue, particularly within the transportation sector. Electric vehicles offer a promising alternative due to their durability and reduced greenhouse gas emissions. However, their rapid adoption has introduced significant challenges, including increased network power losses, deteriorating voltage profiles, and declining substation power factors. This study proposes an approach that integrates fuzzy objective optimization with African Vulture Optimization (AVO) to determine the optimal sitting and sizing of distributed generations (DG), shunt capacitors (SC), and electric vehicle charging stations (EVCS) within radial distribution systems (RDS). The proposed methodology is evaluated on the standard IEEE-69 bus RDS. A detailed comparative analysis between the proposed simultaneous optimization approach for DGs, SCs, and EVCSs and with the traditional two-staged method is presented. The findings indicate that the proposed strategy not only matches but surpasses the performance of existing strategies for the reduction of power losses and enhancement of bus voltage profiles. Key findings include a significant reduction in active and reactive power line loss, with losses minimized by 85.90% and 82.15%, respectively. In addition, an improvement in the minimum bus voltage to 0.98 p.u. is also achieved. Thereafter, the proposed issue is solved in different loading scenarios to present the effectiveness of the approach under different operating conditions. This research effectively demonstrates the complexities introduced by EVCS integration and addresses the issue with simultaneous optimal sitting and sizing of DGs, SCs, and EVCSs that significantly enhance the sustainability and efficiency of RDS.

The world is still facing an old challenge, e.g., environmental change. In many nations, including developing countries such as Indonesia, spurring economic growth is considered the best way to overcome many things. Indonesia is moving the center of the Indonesian Capital City (IKN). By opening up new space through the consideration of equitable economic development toward a green environment, this study is designed to investigate the impact of economic growth on environmental quality and vice versa. The object of analysis is directed at Penajam Paser Utara (PPU) as the new IKN center and four other IKN buffer areas in East Kalimantan, including (1) Paser, (2) Balikpapan, (3) Samarinda, and (4) Kutai Kartanegara. This study uses panel data regression and linear trends. The data elaborated is economic growth based on Regional Domestic Product (GRDP), which is proxied, and environmental quality, as reflected by the Environmental Quality Index (IKLH), during the 2017–2023 period. Referring to the method implemented, there is significant positive causality between the two in the selected IKN areas. Through the linear trend model, it is found that there is a tendency for changes in the data analyzed based on constant time. This study can be an instrument for practical policy making and a breakthrough in the development of a scientific discipline that studies the relationship between economic growth and environmental quality in two directions.
Humanization of Street Median Islands: Utilizing Pedestrian Quality Needs Indicators for Saudi Urban Transformation
Authors: Moussa Rasha A.
Published: February 2025

Saudi Arabia has developed initiatives to transform wide street median islands into vibrant linear gardens that enhance city aesthetics, pedestrian safety, and social cohesion. Despite the significance of these spaces, urban designers often focus on physical aspects (Pedestrian Quality Needs) while ignoring social ones (Users’ Needs) which lead to the deterioration of these spaces, weakening their capability to create a positive user experience. This research aims to bridge the gap between the two aspects and highlight the potential of transforming street median islands into friendly linear spaces. The researcher conducts structured experts’ questionnaires to analyze the pedestrians’ needs and measure the impact of PQN attitudes on them to indicate the most effective indicator needed for each need. Additionally, a quantitative technique using the Statistical Package for the Social Sciences was employed to verify and weigh the importance of the PQN indicators that contribute to developing the suggested integrated framework. This framework is developed to be used for evaluating and improving the performance of these spaces. The study findings emphasize the importance of considering PQN and their impact on creating livable street median islands. Moreover, the results highlight the most effective design considerations to ensure the success of these spaces in generating social sustainability.

Published: February 2025

High-altitude mountainous regions are highly vulnerable to climate and environmental shifts, with the current global climate change exerting a profound influence on the ecological landscape of the Tianshan Mountains in China. This study assesses the ecological security quality in the Tianshan Mountains of China from 2001 to 2020 by employing various remote sensing techniques such as the Remote Sensing Ecological Index (RSEI) for evaluation, Normalized Difference Vegetation Index (NDVI) for fractional vegetation cover (FVC) analysis, the CASA model for estimating vegetation primary productivity (NPP), and a carbon source/sink model for calculating the net ecosystem productivity (NEP) of vegetation. The research also delves into the evolutionary trends and impact mechanisms on the ecological environment using land use and meteorological data. The findings reveal that the RSEI’s principal component (PC1) exhibits significant explanatory power, showing a notable increase of 5.90% from 2001 to 2020. Despite relatively stable changes in the RSEI over the past two decades covering 61.37% of the study area, there is a prevalent anti-persistence pattern at 72.39%. Notably, NDVI, FVC, and NPP display upward trends in vegetation characteristics. While most areas in the Tianshan Mountains continue to emit carbon, there is a marked increase in NEP, signifying an enhanced carbon absorption capacity. The partial correlation coefficients between the RSEI and temperature, as well as precipitation, demonstrate statistically significant relationships (p < 0.05), encompassing 6.36% and 1.55% of the study area, respectively. Temperature displays a predominantly negative correlation in 98.71% of the significantly correlated zones, while precipitation exhibits a prevalent positive correlation. An in-depth analysis of how climate change affects the quality of the ecological environment provides crucial insights for strategic interventions to enhance regional environmental protection and promote ecological sustainability.
Toward a Quantum Computing Formulation of the Electron Nuclear Dynamics Method via Fukutome Unitary Representation
Authors: Dominguez Juan C. , de Farias Ismael , Morales Jorge A.
Published: February 2025

We present the first step toward the quantum computing (QC) formulation of the electron nuclear dynamics (END) method within the variational quantum simulator (VQS) scheme: END/QC/VQS. END is a time-dependent, variational, on-the-flight, and non-adiabatic method to simulate chemical reactions. END represents nuclei with frozen Gaussian wave packets and electrons with a single-determinantal state in the Thouless non-unitary representation. Within the hybrid quantum/classical VQS, END/QC/VQS currently evaluates the metric matrix M and gradient vector V of the symplectic END/QC equations on the QC software development kit QISKIT, and calculates basis function integrals and time evolution on a classical computer. To adapt END to QC, we substitute the Thouless non-unitary representation with Fukutome unitary representation. We derive the first END/QC/VQS version for pure electronic dynamics in multielectron chemical models consisting of two-electron units with fixed nuclei. Therein, Fukutome unitary matrices factorize into triads of one-qubit rotational matrices, which leads to a QC encoding of one electron per qubit. We design QC circuits to evaluate M and V in one-electron diatomic molecules. In log2-log2 plots, errors and deviations of those evaluations decrease linearly with the number of shots and with slopes = −1/2. We illustrate an END/QC/VQS simulation with the pure electronic dynamics of H2+ We discuss the present results and future END/QC/QVS extensions.
L2,1-Norm Regularized Double Non-Negative Matrix Factorization for Hyperspectral Change Detection

Published: February 2025

Hyperspectral image (HSI) change detection (CD) is an important technology for identifying surface changes using multi-temporal HSIs. Nevertheless, the high dimensionality of HSIs presents significant challenges for CD tasks, including issues such as lack of robustness and high computational costs in existing methods. To address those issues, this paper proposes an unsupervised simple and effective HSI CD model termed L2,1-norm regularized double non-negative matrix factorization (L2,1-DNMF). Specifically, the proposed model employs a symmetric double non-negative matrix factorization (NMF) framework to jointly analyze multitemporal HSIs, capturing their common and invariant structural information to construct a shared feature basis. Meanwhile, two non-negative feature weight matrices are learned to generate a differential image matrix that directly reflects the change regions. To enhance robustness against noise, an L2,1-norm constraint is imposed on the difference image matrix, ensuring that unchanged areas exhibit near-zero values while changed areas present nonzero values. Finally, comprehensive experiments performed on three benchmark hyperspectral datasets validated the efficacy of the proposed method, which is superior to some state-of-the-art ones regarding detection performance and computational cost.
Roots of Binary Shuffle Squares
Authors: Datko Dominika , Pawlik Bartłomiej
Published: February 2025

A square is a word of the form XX, where X is any finite non-empty word. For example, couscous is a square. A shuffle square is a finite word that can be formed by self-shuffling a word; for instance, the Spanish word acaece is a shuffle square but not a square. We discuss both known and novel enumerative problems related to shuffle squares, with a focus on the number of distinct roots of binary shuffle squares. We introduce the term explicit shuffle squares, propose several conjectures, and present some preliminary results towards their resolution. Our discussion is supported by computational experiments. In particular, we determine the exact number of distinct roots of binary shuffle squares with a length of up to 24. On the other hand, we show that every non-constant binary word of length n generates at least n different shuffle squares.

Authors: Guo Chunlan , Lyu Yang , Li Peng , Kou IokTeng Esther
Published: February 2025

Climate change has profound impacts on tourists’ travel demands, travel decisions, travel experiences, and the development of the tourism industry. Consequently, understanding tourists’ knowledge, attitudes, and practices (KAP) towards climate change is important to the future development of tourism. This study aimed to identify and evaluate the existing literature concerning tourists’ KAP towards climate change through a systematic review. A total of 76 articles were included to provide a comprehensive overview of tourists’ KAP towards climate change since the 1950s. This study identified a significant increase in relevant research output in recent years; however, it also found a noticeable geographical bias, with a concentration in Europe and North America. While tourists generally demonstrated a good understanding of climate change and its impact on tourism, they showed a lack of awareness regarding the environmental consequences of air travel and were reluctant to reduce air travel. Most tourists believed that governments should take the lead in addressing climate change, with only a minority recognizing their individual responsibility. Furthermore, the perceived threats of climate change directly influenced tourists’ travel decisions, prompting them to modify their travel plans, posing a challenge for tourist destinations. These findings can guide the development of policies related to climate education and sustainable tourism practices.

Published: February 2025

A novel double-stranded RNA (dsRNA) virus was isolated and described from strain ZZZ210557 of plant endophyte Allocryptovalsa sichuanensis. The dsRNA virus contains four dsRNA segments, dsRNA1 to dsRNA4, with a size range of 3.8 to 5.1 kbp. Each possesses a single large ORF and is encapsulated in isometric particles approximately 42–47 nm in diameter. Notably, the dsRNA3 encoded sequence revealed modest similarities to the amino acid sequences of RdRps predicted from the nucleotide sequences of known and suspected members of the family Quadriviridae. Phylogenetic analysis of the putative RdRp with the corresponding proteins of other quadriviruses revealed that the dsRNA virus is a new member belonging to the family Quadriviridae, tentatively named Allocryptovalsa sichuanensis quadrivirus 1 (AsQV1). All four segments of AsQV1 could be successfully cured through ribavirin treatment, whereas it likely has no apparent impact on the morphologies or virulence of the host fungus. This study is the first report of a quadrivirus isolated from the fungus A. sichuanensis, and our results enhance the diversity of the quadrivirus.

Published: February 2025

Since the introduction of prophylactic HPV vaccines, both HPV infection rates and cervical cancer rates have subsequently dropped. Yet, cervical cancer remains the fourth most common cancer diagnosis in women globally. As HPV and its role in the development of cervical cancer become better understood, vaccines have emerged as a front runner for improved therapeutic cervical cancer treatment. Recent studies have shown that protein and DNA vaccines may be effectively delivered via the use of several different vectors, while combination therapy with immune checkpoint inhibitors provides even more effective treatment. Further investigation and additional clinical studies into specific vaccine strategies are necessary to determine how effective vaccines are as therapeutic treatment for cervical cancer. This review intends to summarize some of the most promising research on cervical cancer vaccines. Such a study may be helpful for gynecologists to prevent and manage patients with HPV infection.

A methodology was developed for the implementation of solar thermal and photovoltaic energy in an establishment dedicated to the production of tortillas with an electrical consumption between 491 kWh and 572 kWh per year, with a consumption of 2,235 liters of LP gas weekly. The available solar resource was determined at an angle of 22 ° using the Liu & Jordan method, and the F-Chart method was also used for thermal sizing. For photovoltaic sizing, the critical month was selected, and the peak power that the photovoltaic system must have to generate the energy consumed by the electrical loads was also determined. It was calculated that 511.4 kg of LP gas and 2,984.76 kWh of electrical energy will be saved per year.

The useful life of an infrastructure depends on the preventive maintenance provided during its use, however, abandonment due to various situations accelerates the deterioration of the elements that comprise it, so it is necessary to rehabilitate them by carrying out mandatory modeling and simulation in the real conditions in which the structure is located. Therefore, this work shows the modeling under real corrosion conditions of structural profiles that make up the support system of the steps of a stadium. It is determined that all the structural elements that make up the educational infrastructure require reinforcements due to the reduction in thickness due to corrosion, this is because the portable capacity of the stadium is reduced.

There are various artificial intelligence tools that generate texts, videos, audios, images, presentations, mind maps and essays, significantly supporting the educational field. However, it is important to consider the ethical implications of their use and development. Therefore, this chapter proposes the design of virtual learning objects (VLOs) to promote ethics in the use and development of artificial intelligence in higher education. The methodology employed is based on content analysis, focusing on the use of VLOs in the educational context, the ethical challenges associated with artificial intelligence, and the relevant ethical theories. It is concluded that VLOs bring significant benefits to education and can be effective in promoting ethics in artificial intelligence; it is essential to consider in its design the ADDIE methodology, the types of VLOs and ethical theories such as utilitarianism, deontology, the ethics of virtue, justice and care, in addition to principles such as simplicity, coherence, clarity, aesthetics and time.
