Authors: Ju Xiaoyu , Zhou Xiaoli , Zhang Liangwei , Ma Chun-Ai , Zhang Yue
Published: February 2024

As a major resource region, Xinjiang is both China’s energy security base and an important hub connecting Asia and Europe. Following the country’s call for carbon emission reduction, the Xinjiang government proposes to accelerate the construction of eight major industrial clusters in 2023. The concept of sustainable development is also reflected in the industrial clusters in areas such as new energy. In this study, we combined panel data from 14 regions and cities in Xinjiang from 2006 to 2020 and analyzed the synergy between the development of industrial clusters, carbon emissions, and economic growth using a coupling coordination degree model. Subsequently, we used the super-efficiency slack-based measure (SE-SBM) and Dagum’s Gini coefficient to analyze the spatial disequilibrium of efficiency measures and efficiency cases. The results show the following: (1) Overall, the industrial clusters, carbon emissions, and economic growth in the 14 regions and cities of Xinjiang are not well coordinated. The best reported level has been medium coordination, but there exists a certain degree of correlation among the three. (2) Low-carbon economic efficiency under the influence of industrial clusters in the 14 regions and cities shows significant regional differences. The regions and cities with low-carbon economic efficiency greater than 0.8, which is significantly better than the other regions in terms of efficiency, are all located in northern Xinjiang. (3) During the study period, the overall regional difference in low-carbon economic efficiency under industrial clusters in Xinjiang decreased from 0.183 to 0.17. However, the regional differences were still large. The conclusions indicate that policies for industrial clusters in Xinjiang can promote industrial development, and there may be a correlation between them and the low-carbon economy. This will effectively contribute to local sustainable development. However, overall regional differences are significant, and the degree of coordination is low. Therefore, we suggest that the government can share the advantages of development by constructing cross-regional cooperation platforms. At the same time, the Xinjiang government should make full use of the rich local wind and solar energy resources and explore a low-carbon path toward transforming the traditional energy industry. It can also be seen that industrial clusters in Xinjiang can effectively promote local sustainable development.

Tsunamis are a substantial natural threat in Thailand, as evidenced by the 2004 Indian Ocean tsunami. Effective evacuation is vital to reduce casualties and property damage. However, despite improved warning systems, high death tolls still occur, indicating complex evacuation behavior influenced by various factors. This study examines these factors among diverse groups in Phuket and Phang Nga, Thailand. A survey of 1000 locals, non-local workers, and travelers assesses threat and coping appraisals, past tsunami experiences, gender, age, and tsunami evacuation intention and action selection. Partial Least Squares Structural Equation Modeling (PLS-SEM) was used to analyze the data based on the hypotheses related to the Protection Motivation Theory (PMT). The results of the analyses show that threat and coping appraisals significantly predict tsunami evacuation intention, and gender influences threat perception related to evacuation. Variations among respondent types emphasize the need for tailored disaster preparedness and response strategies. This study offers crucial insights for policymakers, emergency responders, and disaster management stakeholders, underlining the significance of further research into the intricate interplay of individual and contextual factors shaping tsunami evacuation behavior.
Bee Venom: Composition and Anticancer Properties
Authors: Gajski Goran , Leonova Elina , Sjakste Nikolajs
Published: February 2024

Among the various natural compounds used in alternative and Oriental medicine, toxins isolated from different organisms have had their application for many years, and Apis mellifera venom has been studied the most extensively. Numerous studies dealing with the positive assets of bee venom (BV) indicated its beneficial properties. The usage of bee products to prevent the occurrence of diseases and for their treatment is often referred to as apitherapy and is based mainly on the experience of the traditional system of medical practice in diverse ethnic communities. Today, a large number of studies are focused on the antitumor effects of BV, which are mainly attributed to its basic polypeptide melittin (MEL). Previous studies have indicated that BV and its major constituent MEL cause a strong toxic effect on different cancer cells, such as liver, lung, bladder, kidney, prostate, breast, and leukemia cells, while a less pronounced effect was observed in normal non-target cells. Their proposed mechanisms of action, such as the effect on proliferation and growth inhibition, cell cycle alterations, and induction of cell death through several cancer cell death mechanisms, are associated with the activation of phospholipase A2 (PLA2), caspases, and matrix metalloproteinases that destroy cancer cells. Numerous cellular effects of BV and MEL need to be elucidated on the molecular level, while the key issue has to do with the trigger of the apoptotic cascade. Apoptosis could be either a consequence of the plasmatic membrane fenestration or the result of the direct interaction of the BV components with pro-apoptotic and anti-apoptotic factors. The interaction of BV peptides and enzymes with the plasma membrane is a crucial step in the whole process. However, before its possible application as a remedy, it is crucial to identify the correct route of exposure and dosage of BV and MEL for potential therapeutic use as well as potential side effects on normal cells and tissues to avoid any possible adverse event.
Alleviative Effect of Rutin on Zearalenone-Induced Reproductive Toxicity in Male Mice by Preventing Spermatogenic Cell Apoptosis and Modulating Gene Expression in the Hypothalamic–Pituitary–Gonadal Axis

Published: February 2024

Zearalenone (ZEN) is a non-steroidal estrogenic mycotoxin found in many agricultural products and can cause reproductive disorders, mainly affecting spermatogenesis in male animals. Rutin (RUT) is a natural flavonoid compound recognized for its significant antioxidant, anti-inflammatory and estrogenic properties. The present study aimed to determine the protective role of RUT against ZEN-induced reproductive toxicity in male mice. Twenty-four adult Kunming male mice were divided into four groups: control, RUT (500 mg/kg RUT), ZEN (10 mg/kg ZEN), ZEN + RUT (500 mg/kg RUT + 10 mg/kg ZEN), with six replicates per treatment. The results indicated that RUT mitigated ZEN-induced disruption in spermatogenic cell arrangement, decreased spermatozoa count, and increased sperm mortality in the testes. RUT significantly restored ZEN-induced reduction in T, FSH, LH, and E2 serum levels. Moreover, RUT mitigated ZEN-induced apoptosis by increasing the mRNA expression level of bcl-2, decreasing the mRNA expression level of kiss1-r, and decreasing the protein expression level of caspase 8 in reproductive tissues. These findings indicate the protective role of RUT against ZEN-induced reproductive toxicity in male mice by regulating gonadotropin and testosterone secretions to maintain normal spermatogenesis via the HPG axis, which may provide a new application direction for RUT as a therapeutic agent to mitigate ZEN-induced reproductive toxicity.
Potential Serological Misdiagnosis of Barmah Forest Virus and Ross River Virus Diseases as Chikungunya Virus Infections in Australia: Comparison of ELISA with Neutralization Assay Results
Authors: Kizu Joanne , Graham Melissa , Liu Wenjun
Published: February 2024

To evaluate the frequency of errors in the diagnosis of medical laboratory-diagnosed Chikungunya virus (CHIKV) infections in Australia, we studied 42 laboratory-diagnosed CHIKV serum samples from one Queensland medical laboratory by ELISA IgG/IgM and measured the specific neutralization antibodies (Nab) against Barmah Forest virus (BFV), CHIKV and Ross River virus (RRV). The sero-positivity rates for the sera were as follows: anti-BFV IgG+ 19% (8/42), IgM+ 2.4% (1/42) and Nab+ 16.7% (7/42); anti-CHIKV IgG+ 90.5% (38/42), IgM+ 21.4% (9/42) and Nab+ 90.5% (38/42); anti-RRV IgG+ 88.1% (37/42), IgM+ 28.6% (12/42) and Nab+ 83.2% (35/42), respectively. Among the samples with multiple antibody positivity, 2.4% (1/42) showed triple ELISA IgM+, and 14.3% (6/42) exhibited double IgM RRV+CHIKV+; 9.5% (4/42) showed triple IgG+, 76.2% (32/42) displayed double IgG RRV+CHIKV+, 4.8% (2/42) showed IgG BFV+RRV+ and 4.8% (2/42) showed IgG BFV++CHIKV+; and 9.5% (4/42) showed triple Nab+ and 69% (29/42) exhibited double Nab RRV+CHIKV+, respectively. Our analysis of the single-virus infection control Nab results suggested no cross-neutralization between RRV and BFV, and only mild cross-neutralization between CHIKV and RRV, BFV and CHIKV, all with a ≥4-fold Nab titre ratio difference between the true virus infection and cross-reactivity counterpart virus. Subsequently, we re-diagnosed these 42 patients as 1 BFV+, 8 CHIKV+ and 23 RRV+ single-virus infections, along with five RRV+/BFV+ and four RRV+/CHIKV+ double infections, and one possible RRV+/BFV+ or RRV+CHIKV+, respectively. These findings suggests that a substantial proportion of medically attended RRV and BFV infections were misdiagnosed as CHIKV infections, highlighting the imperative need for diagnostic laboratory tests capable of distinguishing between CHIKV infections and actively co-circulating RRV and BFV. For a correct diagnosis, it is crucial to consider reliable diagnostic methods such as the neutralization assay to exclude RRV and BFV.

Published: February 2024

This work describes the antimycotic activity of propolis from the stingless bees Scaptotrigona mexicana and Tetragonisca angustula, collected from two Mexican regions (Veracruz and Chiapas, respectively), against three clinical isolates and the reference strain ATCC 14522 of Malassezia pachydermatis, the causative agent of canine otitis. The chemical components of the ethanolic extracts of propolis were determined by gas chromatography coupled with mass spectrometry (GC-MS), and sesquiterpenes were the predominant compounds. The antimycotic activity was evaluated by plate microdilution. The induced changes in the yeasts were evaluated by fluorescence microscopy and staining with calcofluor white and propidium iodide. The minimum inhibitory concentration (MIC) was 7.11 mg/mL, and the minimum fungicidal concentration was 21.33 mg/mL for both extracts. The EPPs of Scaptotrigona mexicana and Tetragonisca angustula caused substantial damage to yeast morphology, where the propidium iodide staining of the yeasts treated with both EEPs revealed the penetration of this marker, which indicates the destruction of the cell wall and plasma membrane of the fungi. This result suggests that these types of propolis could be used as alternative treatments for canine external otitis. To the best of our knowledge, this seems to be the first scientific report that has demonstrated structural damage in Malassezia pachydermatis by Mexican stingless bee propolis.
Review of the Occurrence of Herbicides in Environmental Waters of Taihu Lake Basin and Its Potential Impact on Submerged Plants
Authors: Zhang Yangyang , Hu Min , Li Aimin
Published: February 2024

Over the past 20 years, a series of problems caused by eutrophication in Taihu Lake, and its surrounding environmental waters has received sustained and widespread attention. With the gradual extinction of submerged plants, which are the important basis for maintaining the aquatic ecological health of lakes, Taihu Lake has shifted from a grass-type clearwater lake to an algae-type turbid lake, posing severe challenges to the aquatic ecological health and security in this region. In addition, the occurrence of herbicides in the environmental waters of the Taihu Lake region has attracted the attention of several researchers. This study reviewed the evolution of submerged plants in Taihu Lake over recent decades. Moreover, the use of herbicides in the Taihu Lake region and their environmental occurrence in the past 20 years were statistically analyzed, and their toxic effects on submerged plants in previous reports summarized. Then, the potential impact of the environmental occurrence concentration of herbicides on submerged plants in the Taihu Lake region was evaluated. In conclusion, according to the results reported in the past paper, the environmental herbicide concentration in Taihu Lake has sometimes reached a level that can affect a variety of submerged plants, especially in the germination stage, which means that as an important cause of the degradation of submerged plants in shallow lakes, the effect of herbicides needs to be paid more attention to. The results of this review offer significant guidance for promoting science-based and standard use of herbicides and preventing their ecological risks in this region.

Published: February 2024

The aquifers of the Togolese coastal sedimentary basin are the principal sources of water for almost half of the country’s population. These aquifers’ features have not been adequately monitored and studied. The resource is threatened by human activities, notably agriculture, industry, and withdrawals for drinking water supplies. This situation is exacerbated by the potential effects of climate change. For this research, a basin-scale study was conducted to estimate current groundwater recharge and its future evolution in response to climate change. A recharge model based on Thornthwaite–Mather balance equations using runoff coefficients characterizing land use was fed with current and future climate data from an optimistic scenario (RCP 4.5) and a pessimistic scenario (RCP 8.4). Despite the associated uncertainties, the soil–water balance model at monthly time steps predicts a recharge of 3 to 455 mm per year from 2020 to 2039, and 40 to 420 mm per year from 2040 to 2059 under the optimistic RCP 4.5 scenario. According to the pessimistic RCP 8.5 scenario, the recharge will range between 16 and 515 mm per year from 2020 to 2049 and from 1 to 467 mm per year between 2040 and 2059. As a result, the basin’s groundwater recharge range, which is currently 47 to 225 mm, will significantly increase. This study provides a scientific basis for the sustainable management of groundwater in the Togolese coastal sedimentary basin. The recharge of the groundwater in the basin will increase regardless of the climate scenario and will support future development in the Togolese coastal sedimentary basin.

Published: February 2024

Floods are among the most devastating and financially burdensome natural disasters in Europe. The combined impact of climate change and land use change is expected to exacerbate and intensify the destructive consequences of river floods. In this study, we analysed the effects of wetland restoration on peak and base flows and on water quality in the Kylldal catchment of the Kyll River in the German Middle Mountains using the Soil and Water Assessment Tool+ (SWAT+). Monthly median daily discharge increases varied between 3% and 33% in the studied (micro)catchments. The higher median flow rates show that discharge peaks were attenuated and distributed over a longer period, making both extreme peak flows and low flows less common. Peak flows tended to decrease, with the largest effects between late fall and early spring when peak flow values decreased by up to 18%. The annual maximum peak flows in each of the three micro-catchments decreased by 12–24% on average. The occurrence of daily average flow rates larger than 1 m3 s−1 was up to 45% lower after wetland restoration. Low flows increased by up to 21% and 13% in the summer and fall, respectively, which suggests that drought risk also decreases after wetland restoration. Average nitrogen exports decreased by 38–50% in the project areas and by 20% at the catchment level. Average phosphorus exports decreased by 52–67% in the project areas and by 25% at the catchment level. The study highlights the potential of wetland restoration for improving hydrological services, mitigating flood risks, and enhancing water quality. Restoring and maintaining freshwater ecosystems and their natural sponge functions is crucial for effectively managing water resources and addressing the challenges posed by climate change and land use changes.

Published: February 2024

In most parts of the world, groundwater is the main source of their water supply, particularly during periods of drought when surface water is scarce. As a result, groundwater drought is among the most worrying problems of our time. In order to shed light on the diversity of scientific productions related to this theme, this analysis was conducted on 151 publications, 76 sources, and 469 authors using version 4.3.1 of Rstudio’s Bibliometrix tool. The clusters and keyword occurrence analysis reveals a research trend towards the use of advanced technologies and a more holistic approach that takes into account the complexity of hydrological systems. The use of drought indices to characterize and monitor groundwater drought, as well as satellite products and their assimilation into Land Surface Models are among the adopted solutions. This was endorsed through a summary of the five most cited publications in this field. The results also highlighted the performance of Chinese institutions in analyzing the various aspects related to this topic, as well as a lack of international collaboration between research structures. In conclusion, this study has enabled us to present the evolution and trends in scientific research and helped to specify the main emerging themes and future areas of research related to groundwater drought.

Published: February 2024

This research aims to discuss the importance of upholding human rights principles (HRP) in teacher profession policies, particularly regarding the appointment of Functional Teacher positions as PPPK civil servants. This study employs a juridical-normative method with a human rights-based approach to evaluate related policy regulations. The research findings indicate that the designation of the Functional Teacher Position as a PPPK civil servant violates HRP principles such as equality, interconnectedness, and non-discrimination. Therefore, a re-evaluation of this policy is necessary, considering HRP principles, and reinstating the status of the Functional Teacher Position as PNS civil servants in the SSCASN process. This research is descriptive, utilizing data from legislation, books, and scholarly articles related to HRP. Thus, understanding and respecting HRP principles are crucial in establishing teacher profession-related policies.

Published: February 2024

This paper aims to analyze patterns and causes of epidemics in the novels Metamorphoses, The Good Earth, The Seventh Seal, and Cat’s Cradle. Through the approach of intertextual theory and the hermeneutic method, common patterns are identified, namely family disintegration, unnatural births, and epidemics. The cause of these epidemics is infidelity or deviation within the family, seen as a divine punishment upon humanity. These findings highlight the relationship between literary texts and social phenomena, offering insights into how literary narratives reflect and shape our understanding of epidemics and human behavior. The implications of this analysis can provide a deeper understanding of human complexity and the relevance of literature in illuminating significant aspects of human experience, such as epidemics and morality.

Published: February 2024

This paper examines the relationship between students' attitudes toward chemistry and their academic performance in undergraduate chemistry courses. A sample of 378 chemistry students of Arts and Science Colleges from Madurai Educational District completed the Chemistry Attitudes Scale and consented to the release of their chemistry course grades. Correlational analyses using Pearson's ‘r’ found moderate positive correlations between chemistry attitudes and course grades (r = .32, p < .001), indicating students with more favourable attitudes tended to achieve higher grades. The correlation was strongest for inorganic chemistry (r = .43, p < .001) and weakest for physical chemistry (r = .21, p = .02), though ANOVA results showed no significant differences by chemistry subdiscipline. The results support the hypothesis that favourable chemistry attitudes are associated with greater academic success. This highlights the importance of affective variables and the potential value of interventions targeting chemistry attitudes among undergraduates

¿Qué medimos cuando medimos democracia?: convenciones, espacios de lucha e implicaciones
Authors: Jesús Guzmán Castillo
Published: February 2024

En los últimos años la literatura y las discusiones en la ciencia política giran en torno a la crisis de la democracia y a los retrocesos democráticos que viven los distintos países en diversas regiones, tanto en democracias nuevas como en aquellas consolidadas. Mucho de este debate surge de las mediciones que se hacen sobre la calidad de la democracia, y los resultados de estas reflejan cómo cada vez menos personas viven en democracia. Sin embargo, poco se ha reflexionado sobre el origen de estas mediciones y los impactos que pueden tener. En este artículo se discute sobre el proceso de medición de la democracia, partiendo del hecho de que es un objeto cuya conceptualización es un campo de disputa y que el proceso de medición parte de una serie de decisiones subjetivas que provienen de convenciones aceptadas entre comunidades científicas, pero también políticas y económicas.

Dynamic characteristics and deep reinforcement learning of proportional-integral-differential controller for quadruped stator-based ultrasonic linear motor
Authors: Jiang Yukun , Wang Fangyi , Sasamura Tatsuki , Mustafa Abdullah , Morita Takeshi
Published: February 2024

Ultrasonic linear motors have many advantages, such as small size, light weight, and a lack of electromagnetic interference. In our previous study, a quadruped stator-based ultrasonic linear motor that mimics the motion of an inchworm based on longitudinal and bending modes was proposed. However, our previous studies focused on voltage control, overlooking the influence of phase, which made accurate and sustainable operation difficult. This study measures the dynamic characteristics of this motor using polymer-based rods and combines deep reinforcement learning (DRL) with proportional-integral-differential (PID) algorithms for both position and speed control through phase manipulation. The proposed DRL-PID controller outperforms voltage control in both simulation and real-world experiments.

Even though some experimental results have been shown in previous literature as evidence of single-particle detection, these results have not been verified from a theoretical point of view. Here, the performance of a CW-CDL with single-particle detection is investigated. Examples of single-particle detection that have been reported in previous literature are verified using theoretical simulation. Furthermore, comparison of signal detection ability between single- and multiple-particle cases is also performed theoretically.

Ultra-small (10 μm) InGaN-based red microLEDs (625 nm at 1 A cm−2) are necessary for modern displays. However, an increase in surface-area-to-volume ratio with a decrease in the micro-LED size resulting in higher surface recombination causes a drop in efficiency with device size. In this letter, we demonstrate microLEDs from 60 μm down to 3 μm with significantly reduced sidewall-related efficiency reduction using a two-step passivation technique using Al2O3 and Si3N4. The peak on-wafer EQE changes from 0.21% to 0.35% as the device size reduces from 60 to 3 μm, possibly due to improved light extraction efficiency for smaller mesa-widths.

The aim: to analyze the development of domestic fisheries in the Atlantic and Southeastern Pacific Oceans in 2000–2020, to assess the state of stocks and catch of the most important types of aquatic biological resources.

Methods: conducting trawl-a coustic, ichthyological and hydrological accounting studies in 2000–2020. Analysis of domestic and foreign literature.

Novelty: the article presents an up-to-date analysis of the development of Russian fishing, the intensity of fishing and the state of exploited stocks of commercial fish species.

Results: Information is provided on the status and dynamics of stocks and catch of commercial aquatic organisms in various areas of the Atlantic and southeastern Pacific Ocean. During the period under review, the highest biomass of stocks and catch are observed in pelagic fish species in the North-East Atlantic. The state of stocks and catch of bottom fish species in the far North Atlantic regions are at an average or low level. In general, in the first two decades of the XXI century, favorable conditions for conducting domestic fishing were noted. For the Central-Eastern Atlantic area (EEZ of Morocco and Mauritania), information is provided on the status of the main commercial fish stocks. Particular attention was paid to the possibility of resuming the domestic tuna and mackerel fishery in the south-e astern Pacific Ocean.

Practical significance: the results of the analysis can be used to make management decisions on the development and regulation of fishing.
State Production and Market at Ebla – Animal and Wool Values
Authors: Archi Alfonso
Published: February 2024

The kingdom of Ebla covered an area extending around 200 km from north to south and from east to west; that is, from the modern Syrian-Turkish border down to the oasis of Ḥama in the south, and from the Amuq plain, where the delta of the Orontes River flows into the Mediterranean Sea, up to Emar, its allied city, whose territory reached the Euphrates. The Central Administration – the Palace – had at its disposal the revenues from its own administrative organization, with its workshops, as well as from the “village communities”, represented by a large number of “Elders”. Notwithstanding that, Ebla’s envoys also acquire several types of goods, such as mules, cattle and sheep, garments and wool, from the markets of the cities in its own kingdom, and in other city-states, primarily from its archival, Mari. Luxury goods, on the other hand, were mostly acquired on the basis of ceremonial gifts from court to court. Long-distance-trade, however, was not relevant in the formation of the Syrian regional states. Goods (including the tributary deliveries its officials owed the Palace) were given also values in silver, and small goods, such as aromatic essences, were valued in wool. The average value of a head of cattle was around 25 shekels of silver, while a sheep was worth between 1 and 1½ shekels. It is not possible to establish the exact value of the weight used for wool. These prices are in any case much lower compared to those used in Mesopotamia during the Ur III period.
COMPARISON OF CLASSICAL AND FUZZY EDGE DETECTION METHODS

Edge detection is one of the challenging problems in image processing. Four different classical edge detection methods—Sobel, Prewitt, Roberts, and Canny—and type-1 and type-2 fuzzy logic-based edge detection methods are applied to analyze two separate datasets with various properties. The datasets are STARE which contains medical images of the retina and BIPED which contains images of the street. Furthermore, two separate hybrid fuzzy logic methods are implemented. The type-1 and type-2 fuzzy inference techniques are combined to produce the hybrid-1 and hybrid-2 approaches, using the "AND" and "OR" logic operators. We compare the simulation results for each technique using three different image quality metrics. These are Mean Square Error (MSE), Peak Signal Noise Ratio (PSNR), and Structural Similarity Index (SSIM). The type-2 fuzzy technique outperformed the hybrid-1 fuzzy method in visual quality metrics comparison, demonstrating superior blood vessel recognition on the STARE retinal image dataset—a dataset that more closely resembles the human visual system. Using the BIPED street image dataset, the hybrid-1 fuzzy approach outperformed the Roberts method. The hybrid-1 fuzzy technique showed good results in the second order for both kinds of datasets. Any data and general applications can take advantage of it.

As a major pillar of global energy production, coal mining requires continuous advancements in efficiency to contribute to the broader goal of energy sustainability, all the while the shift towards more sustainable energy sources is underway. Mechanized excavation systems employed in underground coal mines, particularly within the longwall mining method, enable high-tonnage coal production. The Longwall Top Coal Caving (LTCC) method, one of the longwall mining techniques, has been developed for the effective extraction of coal from thick coal seams. However, as mining operations delve deeper, various complex issues, such as gallery cross-sectional variation, emerge. Gallery cross-sectional variation can increase the risk of collapse by affecting the stress distribution in the rock mass, posing a threat to worker safety. This study centers on the numerical modeling and analysis of gallery cross-sectional variation in the Ömerler underground mine, operated by the Turkish Coal Enterprises (TKI), West Lignite Enterprise (GLI). To achieve this objective, an extensive database was established through field and laboratory rock mechanics studies. This database was then utilized in the Fast Lagrangian Analysis of Continua 3D (FLAC3D) (v6.0) program to simulate the cross-sectional variations of the A6 panel in the Ömerler underground mine. The numerical simulation results provide valuable insights into the secondary stress-deformation changes associated with gallery cross-sectional variation.
