Abstract
Objective
This retrospective study aimed to analyse the correlation between somatostatin receptor subtypes (SSTR 1–5) and maximum standardized uptake value (SUVmax) in meningioma patients using Gallium-68 DOTA-D-Phe1-Tyr3-octreotide Positron Emission Tomography ([68Ga]Ga-DOTATOC PET). Secondly, we developed a radiomic model based on apparent diffusion coefficient (ADC) maps derived from diffusion weighted magnetic resonance images (DWI MRI) to reproduce SUVmax.

Method
The study included 51 patients who underwent MRI and [68Ga]Ga-DOTATOC PET before meningioma surgery. SUVmax values were quantified from PET images and tumour areas were segmented on post-contrast T1-weighted MRI and mapped to ADC maps. A total of 1940 radiomic features were extracted from the tumour area on each ADC map. A random forest regression model was trained to predict SUVmax and the model’s performance was evaluated using repeated nested cross-validation. The expression of SSTR subtypes was quantified in 18 surgical specimens and compared to SUVmax values.

Results
The random forest regression model successfully predicted SUVmax values with a significant correlation observed in all 100 repeats (p < 0.05). The mean Pearson’s r was 0.42 ± 0.07 SD, and the root mean square error (RMSE) was 28.46 ± 0.16. SSTR subtypes 2A, 2B, and 5 showed significant correlations with SUVmax values (p < 0.001, R2 = 0.669; p = 0.001, R2 = 0.393; and p = 0.012, R2 = 0.235, respectively).

Conclusion
SSTR subtypes 2A, 2B, and 5 correlated significantly with SUVmax in meningioma patients. The developed radiomic model based on ADC maps effectively reproduces SUVmax using [68Ga]Ga-DOTATOC PET.

AbstractSurface-bounded exospheres result from complex interactions between the planetary environment and the rocky body’s surface. Different drivers including photons, ion, electrons, and the meteoroid populations impacting the surfaces of different bodies must be considered when investigating the generation of such an exosphere. Exospheric observations of different kinds of species, i.e., volatiles or refractories, alkali metals, or water group species, provide clues to the processes at work, to the drivers, to the surface properties, and to the release efficiencies. This information allows the investigation on how the bodies evolved and will evolve; moreover, it allows us to infer which processes are dominating in different environments. In this review we focus on unanswered questions and measurements needed to gain insights into surface release processes, drivers, and exosphere characterizations. Future opportunities offered by upcoming space missions, ground-based observations, and new directions for modelling are also discussed.
The societal role of universities and their alliances: the case of the EuroTeQ Engineering University

Published: September 2023

AbstractWe analyse the creation of European university alliances as an effort to build learning networks between universities in light of newly perceived needs in Europe. The rationales for such alliance formation include cultural integration, grand societal challenges and reforms in the European innovation ecosystem. We consider how alliance formation may be instrumental in achieving closer cooperation and understand alliances as learning networks where universities can share know-how, define strategies and pursue moral reflection. How such learning may take place is illustrated with a case study of the “EuroTeQ Collider”, a joint educational programme by one of the European university alliances. The case illustrates how uneven experience with novel educational formats and stakeholder engagement creates opportunities for exchange and how formulating a common language for joint activities can make universities align their strategies and deliberation.

AbstractMicroplastics are becoming an increasingly common pollutant that can pose a threat to living organisms. The aim of this research was to determine the amount, type, and diversity of microplastics along mountain trails. The study includes three mountain trails, differing in terms of length, difficulty, and number of visitors. The trails were located in the massif of Babia Góra, in the Kościeliska Valley, and Izerska Meadow. During the research, microplastics were determined in snow during the winter period. The research shows high microplastic contamination along the trails. The study area was characterized by the highest content of polyurethane, polyethylene terephthalate, polyethylene, and polypropylene. The tiniest plastic below 0.5 mm dominated in all the sampling points, with a small share of sizes within the range of 3.1–4.0 mm and 4.1–5.0 mm. The isolated microplastics varied in color and shape. The conducted analyses confirm that easier, more frequented trails are characterized by a higher content of microplastics. Trails to Babia Góra, which are more demanding, are characterized by a different composition of microplastics as well as a variety of microplastics in terms of size, shape, and color. In addition, the lower-lying fragments of the examined trails were the most heavily contaminated with microplastics. The results indicate the need for further research on microplastic contamination of the soil environment along mountain trails.

AbstractClimate warming has gradually become a major problem threatening human survival, and countries have begun to pay attention to carbon emissions. Energy conservation and emission reduction has become a central task in China’s economic development since the 14th Five-Year Plan. As the main force of carbon emissions in China, thermal power industry is bound to become the focus of attention in China’s low-carbon development strategy and energy conservation and emission reduction. Moreover, with the marketization of the power industry, the state has joined the market competition at the power generation sectors and the power sale sectors, and implemented the “opening the middle of the two pipes.” Therefore, the coverage of influence of carbon emissions and carbon investment behavior of power generation companies is not limited to itself, but will also be extended to the supply chain level. Based on the above background, this paper evaluates the scientific rationality of low-carbon investment projects of thermal power enterprises from the perspective of low-carbon supply chain, which not only can help enterprises achieve a win–win situation of economic and environmental benefits, but also contribute to the carbon emission reduction of the entire supply chain, thereby promoting China’s entire social and economic energy conservation and emission reduction work.
Evaluating environmental, economic, and social aspects of an intensive pig production farm in the south of Brazil: a case study
Authors: Savian Michelle , da Penha Simon Carla , Holden Nicholas M. 
Published: September 2023

Abstract
Purpose
The objective of this work was to quantify and understand the impacts of intensive pig production at family-farm level. A case study from the west of Santa Catarina State was used to identify adverse issues (hotspots) of pig production by integrating the assessment of the environmental, economic, and social aspects of the system. The quantitative and qualitative indicators calculated can guide and support the decision-making processes for a variety of stakeholders and actors.

Methods
The environmental performance of the pig production system was assessed from cradle-to-farm gate using environmental Life Cycle Assessment methodology set out in ISO 14040 (ISO 2006a). The functional unit (FU) was 1 kg of Liveweight (kg-LW). The structure of the Life Cycle Sustainability Assessment (LCSA) was based on Neugebauer et al. (J Clean Prod 102:165–176, 2015) and Chen and Holden (J Clean Prod 172:1169–1179, 2018), who proposed a tiered framework to evaluate the impacts on the environmental, social, and financial aspects of a product. The economic dimension or Life Cycle Cost (Hunkeler et al. in Environmental life cycle costing. Crc Press, London, 2008) focused on farm-level activities. The social impact was calculated based on the UNEP/SETAC (2009) guidelines.

Results and discussion
The environmental performance of the finishing pig production was slightly lower than reference value for climate impacts, acidification, and eutrophication. The economic impacts tended to be positive, reflecting the efforts of the farmer and employee to maintain high productivity and reduce the number of pig losses in comparison with the reference values. However, this effort did not result in greater profitability, causing low farm income. The impacts of low profitability were not transferred to the employee since the wage were above the reference value. There is a need for more education for small farmers, which is known to have a positive correlation with the adoption of new technologies, thus reducing adverse environmental and social impacts and increasing economic return.

Conclusions
The interaction of social and economic factors suggests it is unlikely that the farm can achieve better environmental performance. The limited economic return and low level of education have a negative impact on the farmer’s capacity to adopt new technologies to improve environmental outcomes. The use of LCSA, based on a consistent model across the three aspects of sustainability, made it possible to understand the interaction of these factors.

Published: September 2023

AbstractWe study nilpotent Lie algebras endowed with a complex structure and a quadratic structure which is pseudo-Hermitian for the given complex structure. We propose several methods to construct such Lie algebras and describe a method of double extension by planes to get an inductive description of all of them. As an application, we give a complete classification of nilpotent quadratic Lie algebras where the metric is Lorentz-Hermitian and we fully classify all nilpotent pseudo-Hermitian quadratic Lie algebras up to dimension 8 and their inequivalent pseudo-Hermitian metrics.

AbstractThe brewery industry generates a huge quantity of brewers’ spent grain (BSG) which can pose waste disposal and pollution problems. Anaerobic digestion of BSG, a recalcitrant lignocellulosic waste, is slow but can be enhanced by bioaugmentation, biostimulation and co-digestion to obtain a higher biogas yield. Hence, the effect of inoculum from brewery wastewater sludge (BWWS), iron (III) chloride (FeCl3) and co-digestion with poultry manure (PM) on the production of biogas from BSG was investigated. Cumulative biogas and biomethane yields of 588.19 NL/kgVS and 400.34 NLCH4/kgVS, respectively, were obtained from a slurry consisting of a blend of 60% BSG and 40% PM plus 15 mg L-1 FeCl3 in BWWS, after 30 day retention time at 37 oC. However, mono-digestion of BSG in only water yielded 402.17 NLbiogas/kgVS and 262.86 NLCH4/kgVS. The synergistic effects of inoculum from BWWS, FeCl3 and poultry manure on anaerobic digestion of BSG resulted in 46% and 52% increases in biogas and methane yields, respectively, compared with BSG mono-digestion. The biogas and biomethane production kinetics were well described by the dual pooled first order, logistic and modified Gompertz models.
Dynamic scheduling method for data relay satellite networks considering hybrid system disturbances

Published: September 2023

AbstractSystem disturbances, such as the change of required service durations, the failure of resources, and temporary tasks during the scheduling process of data relay satellite network (DRSN), are difficult to be predicted, which may lead to unsuccessful scheduling of tasks. A high-efficiency and robust DRSN calls for smarter and more flexible disturbances elimination strategies. Here, we unify the above three system disturbances as temporary task arrival and extend the static scheduling model of DRSN. Specifically, we derive and define a scheduling model that unifies the static scheduling and dynamic scheduling processes. Meanwhile, we propose a k-step dynamic scheduling algorithm considering breakpoint transmission (k-steps-BT) to solve the above model. Based on the principle of backtracking algorithm and search tree, k-steps-BT can eliminate disturbances quickly by rescheduling tasks and can determine the rescheduling scheme when temporary tasks arrive. Finally, extensive experiments are carried out to verify the proposed model and algorithm. The results show that the proposed model and algorithm can significantly improve the task completion rate of dynamic scheduling without drastic adjustments to the static scheduling scheme.
Evolution of tensile strength and cracking in granite containing prefabricated holes under high temperature and loading rate

Published: September 2023

AbstractFor present applications in deep significant rock engineering, including underground repositories of high-level nuclear waste, an exhaustive comprehension of the impacts of high temperature and loading rate effects on the mechanical characteristics of granite emerges as an imperative necessity. Based on the Brazilian splitting test, Brazilian disc specimens with prefabricated holes were meticulously employed to guarantee the occurrence of radial compression failure. Combining microscopic experiments such as scanning electron microscopy and X-ray diffraction, the indirect tensile strength and damage mechanism of granite from the Yueyang area under the action of different temperatures and loading rates were thoroughly investigated. Furthermore, a nonlinear fitting equation between the two factors and tensile strength is suggested. At the same time, a simplified surface crack density based on pixel processing was defined. This allowed for a comparative assessment of how variations in temperature and loading rates induce varying degrees of macroscopic crack development and damage to the specimens. The findings suggest a direct proportionality between the tensile strength of granite and the loading rate, while an inverse proportionality is observed concerning temperature above 400 °C. However, a transient "gain effect" phenomenon manifests at temperatures below 400 °C. However, the impact of temperature on tensile strength is significantly greater than that of the loading rate, exhibiting a difference of approximately 8.7 times. Furthermore, the temperature is more prone to lead to the occurrence of secondary tensile cracks in specimens. The results of this research provide valuable guidance for ensuring the security of deep major rock engineering during construction.

Published: September 2023

AbstractNumerous high-tech advancements have established a healthy environment, reduced consumer consumption of non-renewable resources, and reduced the total ecological impact on the environment. Despite this technology, many people still do not have sustainable behavior ingrained in them. Environmental sustainability is threatened by human behaviors, and environmental choices made by individuals are correlated with pro-environmental behaviors. This research focuses on the relationship between people and the environment, the difficulties that have arisen as a result, and the factors that influence university students' pro-environmental behaviors. It explores the factors influencing university students in the United Arab Emirates to have positive environmental attitudes and behaviors using the Q methodology. The results elucidate several discourses, including connections between knowledge and attitude, the importance of formal and informal education, and necessary economic policies and incentives. The results of this research are consistent with those of other recent studies that place more emphasis on attitude than motivation when it comes to changing behavior towards the environment.
Mystery and History: Revisiting “A Letter to My Husband” by Yunzhen
Authors: Lu Weijing 
Published: September 2023

AbstractIn the late 18th century, the discovery of “A Letter to My Husband” (Jiwai shu), attributed to a woman named Yunzhen, caused great excitement in Beijing. Focusing on the question of how the mysterious letter captured the imagination of the literati, this article employs the strategy of contextualized reading to tease out social and cultural milieus and the textures of sentimentality of its readers. It suggests that the letter's resonating power rests on its dual nature: a self-expression of a talented and exemplary wife and a chronicle of the time when the entanglement of female talent, wifely virtue, marital love, and family tension became integral to the lives of the literati.
Horses of Cyrenaica: breeding and charioteers in the Greek and Roman periods (literary, epigraphical and visual data)
Authors: Abdelhamed Muna H. H. 
Published: September 2023

AbstractOur knowledge about Cyrenaican horses during the Greek and Roman periods is mainly derived from ancient literary sources. They tell us that horses were bred with distinctive skills in this region and report interesting stories highlighting the participation of Cyrenaican horses in athletic games. The literary data suggests Cyrene is a horse-breeding centre and this paper examines whether these assertions represent a reality, or simply a convention. This study investigates and analyses other locally related archaeological data, including epigraphy documents published by the digital corpora ofIGCyrandIRCyr. Although most of the inscriptions in these corpora are published, little attention has been given to horses. The adapted approach here aims to build up a picture about horses using local evidence, with a focus on the linguistic indications of equestrian practice at Cyrenaica and the use of horse-related terms in nomenclature. Interestingly, the regional textual and archaeological data provide us with a similar picture to that presented by the literary references regarding horse breeding in Cyrenaica, charioteer training and their contribution to overseas Greek and Roman sport.
A Right Restricted: Racial Threat and the Sponsorship of Restrictive Voting Laws
Authors: Morris Kevin T. 
Published: September 2023

AbstractIn the aftermath of the United States’ 2020 presidential election, state legislatures have introduced and passed an unprecedented number of restrictive voting bills. While past research has looked at the state-level drivers of restrictive voting legislation, this project explores what factors predict which legislators within states push for these laws. Specifically, I ask whether district-level characteristics predict when lawmakers use bill sponsorship to send messages about their positions beyond those sent by simple roll-call votes. I use theories of geographical threat and racial resentment to predict where sponsorship of these bills is most likely. My results tie these theoretical expectations to observed legislative activity: the whitest state legislative districts in the least-white states were the most likely to be represented by lawmakers who sponsored restrictive bills, as were districts with the most racially resentful white residents. I conclude that, despite lawmakers justifying these restrictive laws by claiming that fraud is a major problem, race and racism are inherently tied to the introduction and passage of these bills. This raises important questions about commitments to multiracial democracy.

AbstractIn recent field studies, suspected gymnophallid metacercariae were histologically located in the mantle of mussels from the Norwegian Sea. Mussels from the sites in which that infection was detected also presented abnormally high pearl numbers. It has been previously described that gymnophallid metacercariae could cause pearl formation processes in mussels, as a host reaction to encapsulate these metacercariae. Given the pathological host reaction these parasites elicit, a study was performed to identify gymnophallid metacercariae found in mussels collected from Tromsø at morphological and molecular level and to assess, by the use of molecular tools, the relationship between the parasite and the biological material inside the pearls. As a result, Gymnophallus bursicola metacercariae infecting Norwegian Mytilus edulis were identified according to morphological characters, along with the first 18S rDNA and COI sequences for this trematode species. In addition, parasite DNA from the core of the pearls was extracted and amplified for the first time, confirming the parasitological origin of these pearls. This procedure could allow identifying different parasitic organisms responsible for the generation of pearls in bivalves.
