AbstractWe present a comprehensive data-based characterization of the subsistence economy of Chalcolithic Cucuteni–Trypillia societies (CTS) on the Moldovian and Suceava plateaus and the Podolian and the Dnieper uplands. This study is based on a quantitative evaluation of archaeobotanical samples from 34 settlement sites, with a focus on Trypillia mega-sites and on stable isotopic analysis of ancient crop residues. The isotopic analysis allows us to identify specific cultivation strategies, which show a close relationship with animal husbandry for manure. We describe the economy of the Trypillia mega-sites as having been based on an elaborate agricultural system, in which the inhabitants knew how to grow crops that could withstand the ecological constraints of growth, especially along the forest steppe ecotone. We also argue that the agglomeration of greater population densities at these mega-sites contributed to landscape change from woodland and forest to open grassland and steppe. Following on from this, we suggest that cultivation practices of the CTS were important in the establishment of the present-day cultural steppe in this region.

AbstractPopulation irruptions of crown-of-thorns seastar (CoTS,Acanthasterspp.) represent a perennial threat to Indo-Pacific coral reefs. Age determination of CoTS is challenging, thereby hindering understanding and management of this nuisance species. Telomeres, which are protective DNA structure found at the ends of eukaryotic chromosomes that shorten at each cell division, have been used to estimate age in wild animals. To investigate the use of telomeres in CoTS, we optimized a quantitative PCR protocol to measure relative telomere length (rTL) in CoTS for the first time. Comparing rTL among four age groups (4, 7, 16, > 24 months post-settlement), we found that adult CoTS generally exhibit shorter rTL than juveniles, which is the first evidence of age-related telomere attrition in CoTS. However, there was large within-age class variation, and no significant relationships were found between adult CoTS rTL and potential age-indicating external features. Furthermore, we found accelerated telomere attrition under sub-optimal diet, where individuals that were fed crustose coralline algae for 16 months exhibited shorter rTL than their counterparts fed on coral. A positive correlation was found between rTL of tube feet and pyloric caeca, suggesting synchronization of telomere dynamics across somatic tissues in CoTS. Overall, our results suggest that rTL could be used to classify CoTS into broad age groups, though individual variation constrains the ability to resolve specific cohorts. The present study contributes to the understanding of telomere dynamics in marine invertebrates, while laying the groundwork for future research into rTL as biomarker for age and potentially stress for CoTS.
Control of nutrient metal availability during host-microbe interactions: beyond nutritional immunity
Authors: Djoko Karrera Y. 
Published: July 2023

AbstractThe control of nutrient availability is an essential ecological function of the host organism in host-microbe systems. Although often overshadowed by macronutrients such as carbohydrates, micronutrient metals are known as key drivers of host-microbe interactions. The ways in which host organisms control nutrient metal availability are dictated by principles in bioinorganic chemistry. Here I ponder about the actions of metal-binding molecules from the host organism in controlling nutrient metal availability to the host microbiota. I hope that these musings will encourage new explorations into the fundamental roles of metals in the ecology of diverse host-microbe systems.

AbstractAging muscle experiences functional decline in part mediated by impaired mitochondrial ADP sensitivity. Elamipretide (ELAM) rapidly improves physiological and mitochondrial function in aging and binds directly to the mitochondrial ADP transporter ANT. We hypothesized that ELAM improves ADP sensitivity in aging leading to rescued physiological function. We measured the response to ADP stimulation in young and old muscle mitochondria with ELAM treatment, in vivo heart and muscle function, and compared protein abundance, phosphorylation, and S-glutathionylation of ADP/ATP pathway proteins. ELAM treatment increased ADP sensitivity in old muscle mitochondria by increasing uptake of ADP through the ANT and rescued muscle force and heart systolic function. Protein abundance in the ADP/ATP transport and synthesis pathway was unchanged, but ELAM treatment decreased protein s-glutathionylation incuding of ANT. Mitochondrial ADP sensitivity is rapidly modifiable. This research supports the hypothesis that ELAM improves ANT function in aging and links mitochondrial ADP sensitivity to physiological function.

Operationalizing the Nature Futures Framework for ecological infrastructure
Authors: Mayer Paula , Rabe Sven-Erik , Grêt-Regamey Adrienne 
Published: July 2023

AbstractScenarios are useful for considering development pathways under different future conditions. To manage a functioning ecological infrastructure (EI) as a network of natural and semi-natural habitats that can promote biodiversity and provide nature’s contributions to people (NCPs), one needs to understand future biophysical and socio-economic influences on its development. However, scenarios often do not incorporate the reciprocity of biophysical and societal changes. This has prompted new proposals from the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES) on the importance of creating nature-centered multiscale scenarios that include a normative dimension accounting for diverse human–nature relationships. In this contribution, we operationalize the Nature Futures Framework (NFF), developed under IPBES, into integrated normative and exploratory scenarios framing the development of a functioning EI in Switzerland until 2060. We follow a two-stage participatory approach methodologically aligned with the IPBES development. First, we elaborated positive visions for future EI with stakeholders in four regions of Switzerland. We then collaborated with experts to create integrated normative and exploratory scenarios through a process comprising literature research, workshops and a survey. By positioning status quo and future scenarios within the Nature Futures Framework, we demonstrate the diversity of nature values in a specific context of EI in Switzerland, thus contributing to the global set of Nature Futures scenarios. Integrating both plausible and desirable developments, these scenarios will serve as a valuable tool in the planning of long-term measures to ensure a functioning EI in Switzerland.
Quaternionic Convolutional Neural Networks with Trainable Bessel Activation Functions
Authors: Vieira Nelson 
Published: July 2023

AbstractQuaternionic convolutional neural networks (QCNN) possess the ability to capture both external dependencies between neighboring features and internal latent dependencies within features of an input vector. In this study, we employ QCNN with activation functions based on Bessel-type functions with trainable parameters, for performing classification tasks. Our experimental results demonstrate that this activation function outperforms the traditionalReLUactivation function. Throughout our simulations, we explore various network architectures. The use of activation functions with trainable parameters offers several advantages, including enhanced flexibility, adaptability, improved learning, customized model behavior, and automatic feature extraction.
Back to Actual Behavior – A Modest Proposal on the Example of Exploratory Behavior in Children on the Autism Spectrum
Authors: Pisula Ewa , Pisula Wojciech 
Published: July 2023

Abstract Autism spectrum is characterized by difficulties in social communication and interactions and limited, restricted patterns of behavior, interests, and activity. It is diagnosed and described on the basis of behavioral characteristics. Therefore, behavior research plays a critical role in better understanding the functioning of this group of children. Studies on their interests and curiosity take mainly the form of experiments on visual and object exploration. We argue that important aspects of behavior might be neglected within these studies and propose to refine the approach by incorporating the achievements of classic ethology, contemporary measurement and analytical tools, and the theory of integrative levels. We conclude with an outline of the proposed approach in a short list of major methodological postulates.
The Origin and Purpose of Legal Protection for the Integrity of Copyright Metadata
Authors: Cadavid Jhonny Antonio 
Published: July 2023

AbstractRights management information is copyright metadata legally protected by copyright law. The origin of such protection was a United States policy for governance of the information superhighway (the internet) and digital networks. The main discussion documents leading up to the WIPO internet treaties reveal that the policy behind protecting the integrity of copyright metadata was aimed at higher objectives of public interest, such as consumer protection, market efficiencies, and authenticity of creative content. Copyright management information was envisaged as one element of digital infrastructures for creating global electronic commerce, but digital copyright was also foreseen as important for the dissemination of cultural heritage. Today these infrastructures have become a reality through legislation on orphan and out-of-commerce works in Europe, and for the licensing and distribution of royalties for musical works and sound recordings in the US. Countries that implement the WIPO treaties or transplant the US law without considering the whole policy behind the protection of copyright metadata are falling into a copyright management gap because, globally, the discovery, visibility, compensation, and monetisation of local content from places without adequate digital rights metadata infrastructures will be more challenging. This article shows that US digital dominance is codifying and writing the DNA of cultural content.
Measuring cognitive flexibility in anorexia nervosa: Wisconsin Card Sorting Test versus cued task-switching

Published: July 2023

Abstract
Purpose
The Wisconsin Card Sorting Test (WCST) is the most common measure of cognitive flexibility in anorexia nervosa (AN), but task-switching paradigms are beginning to be utilized. The current study directly compared performance on a cued task-switching measure and the WCST to evaluate their association in participants with a lifetime diagnosis of AN, and to assess which measure is more strongly associated with clinical symptoms.

Methods
Forty-five women with a lifetime diagnosis of AN completed the WCST, cued color-shape task-switching paradigm, Anti-saccade Keyboard Task, Running Memory Span, Eating Disorder Examination Questionnaire, Depression Anxiety Stress Scales short form and Eating Disorder Flexibility Index.

Results
There was no evidence of a significant association between WCST perseverative errors and cued task-switching switch costs. Results suggest lower working memory capacity is a determinant of higher perseverative error rate. When controlling for mood variables, neither cognitive flexibility measure was a significant independent predictor of symptom severity.

Conclusions
Results provide support for previous suggestions that WCST perseverative errors could occur due to difficulties with working memory, sensitivity to feedback, and issues with concept formation. Cued task-switching paradigms may provide a useful measure of cognitive flexibility for future eating disorders research by reducing task-specific confounds.

Coal petrology, sedimentology and depositional environment of the Parvadeh coals in the Upper Triassic, Tabas Block of Central-East Iran

Published: July 2023

AbstractPeat forming environment strongly influences the economic value of any coal seam and coal-bearing strata. Hence, palaeoenvironmental studies provide important information for coal resource exploration. In this context, detailed studies on selected coals from the Parvadeh Area, Iran, were conducted using sedimentology, coal petrology, X-ray diffraction (XRD), scanning electron microscopy- energy dispersive X-ray analyzer (SEM-EDX), and proximate analysis. The sedimentary facies above and below the coal seams are mainly marine or marine-influenced facies, supporting that the coal-forming mires in the Parvadeh Area developed in a paralic environment, where the base level must be closely related to sea level. Sulfur contents are moderate to high and mark the influence of brackish/marine water, especially during transgression after peat growth in a lower delta plain environment. The peat-forming mires extended on coastal/delta plain lobes. The lower delta plain/coastal plain coals are characterized by lateral continuity and substantial thickness, whereas few coals possibly representing the upper delta plain are thin and more discontinuous. The detrital nature and composition of the numerous partings and the overall high ash yield in the coal seams indicate an active tectonic area with high rates of creation of accommodation space over peat growth. Coal petrology and coal facies analysis exhibits a permanently high water table within a forest swamp and mostly rheotrophic conditions, sometimes with connection to the seawater. According to paleoenvironmental reconstructions, it seems that coal layers may be thicker, with less sulfur (pyrite), but more clastic minerals and partings toward the western part of the area. Although these coal seams presently have low economic potential for the mining operation, partly due to great depth, this humic, high-volatile to medium-volatile bituminous coal may be suitable for exploration of coal bed methane resources.

Published: July 2023

AbstractTrends such as autonomous driving, non-driving related activities and digitalisation are contributing to a revolution in vehicle concept design. An aspect of this is the consideration of future use cases in shaping vehicle architectures. Future user scenarios can help identify relevant use cases, from which the user needs and system requirements can be derived. The derived requirements need to be matched to vehicle functions and architectural modules that can fulfil them. However, the optimal combination of functions and modules can be difficult to identify due to the numerous possibilities. The aim of this paper is to apply a matrix-based methodology that enables the systematic matching of requirements to vehicle functions and/or modules, as well as the identification of an ideal module/function combination for all the considered requirements. An example is presented that considers a requirement specification that has been derived from predetermined user needs. The requirements are matched to suitable functions/modules and the best possible combinations are determined using the proposed matrix-based methodology. Two optimal combinations are selected, one for a vehicle in the entry level segment and the other for a premium vehicle. The results indicate it is possible to determine an optimal combination for both vehicle segments considered, as well as the substantial influence the rating parameters have on the end result. Lastly, it is shown how the results can be applied by concept designers in order to draft tailored, user-orientated interior concepts.
Exploring investor behavior in Bitcoin: a study of the disposition effect
Authors: Schatzmann Jürgen E. , Haslhofer Bernhard 
Published: July 2023

AbstractInvestors commonly exhibit the disposition effect—the irrational tendency to sell their winning investments and hold onto their losing ones. While this phenomenon has been observed in many traditional markets, it remains unclear whether it also applies to atypical markets like cryptoassets. This paper investigates the prevalence of the disposition effect in Bitcoin using transactions targeting cryptoasset exchanges as proxies for selling transactions. Our findings suggest that investors in Bitcoin were indeed subject to the disposition effect, with varying intensity. They also show that the disposition effect was not consistently present throughout the observation period. Its prevalence was more evident from the boom and bust year 2017 onwards, as confirmed by various technical indicators. Our study suggests irrational investor behavior is also present in atypical markets like Bitcoin.
Text-Independent Speaker Recognition System Using Feature-Level Fusion for Audio Databases of Various Sizes
Authors: Chauhan Neha , Isshiki Tsuyoshi , Li Dongju 
Published: July 2023

AbstractTo improve the speaker recognition rate, we propose a speaker recognition model based on the fusion of different kinds of speech features. A new type of feature aggregation methodology with a total of 18 features is proposed and includes mel frequency cepstral coefficient (MFCC), linear predictive coding (LPC), perceptual linear prediction (PLP), root mean square (RMS), centroid, and entropy features along with their delta (Δ) and delta–delta (ΔΔ) feature vectors. The proposed approach is tested on five different sizes of speech datasets, namely the NIST-2008, voxforge, ELSDSR, VCTK, and voxceleb1 speech corpora. The results are evaluated using the MATLAB classification learner application with the linear discriminant (LD), K nearest neighbor (KNN), and ensemble classifiers. For the NIST-2008 and voxforge datasets, the best SI accuracy of 96.9% and 100% and the lowest speaker verification (SV) equal error rate (EER) values of 0.2% and 0% are achieved with the LD and KNN classifiers, respectively. For the VCTK and ELSDSR datasets, the best SI accuracy of 100% and the lowest SV EER of 0% are achieved with all three classifiers using different feature-level fusion approaches, while the highest SI accuracy and lowest EER achieved on the voxceleb1 database are 90% and 4.07%, respectively, using the KNN classifier. From the experimental results, it is observed that the fusion of different features with their delta and delta–delta values shows an increase in speaker identification accuracy of 10–50%, and the EER value for SV is reduced compared to the value obtained with a single feature.

Abstract
Purpose
To assess recommendations for when adult spinal deformity (ASD) patients may return to athletic activities after surgery.

Methods
A web-based survey was administered to members of AO Spine. The survey consisted of surgeon demographic information and questions asking when a patient undergoing a long thoracolumbar fusion (> 5 levels) with pelvic fixation for ASD would be allowed to resume unrestricted range of motion (ROM), non-contact sports, and contact sports postoperatively. Ordinal logistic regression was used to determine predictors for time to resume each activity.

Results
One hundred twenty four members’ responses were included for analysis. The majority of respondents would allow unrestricted ROM within 3 months postop (< 3 months: 81% vs > 3 months: 19%]. For when to return to non-contact sports, the most common responses were “2–3 months” (26.6%), “3–4 months” (26.6%), and “6–12 months” (18.5%). For when to return to contact sports, the majority advised > 4 months postop [> 4 months: “4–6 months” (19.2%), “6–12 months” (28.0%), “ > 12 months” (28.8%) versus < 4 months: “1–2 months” (4.0%), “2–3 months” (1.6%), “3–4 months” (8.8%)]. 8.8% responded they would “never” allow resumption of contact sports.

Conclusion
There was significant variation between surgeons’ recommendations for resumption of unrestricted range of motion and sports following long fusion with pelvic fixation for ASD. An evidence-based approach to activity recommendations will require information on outcomes and complications.
