Flexemes in theory and in practice
Authors: Pellegrini Matteo 
Published: July 2023

AbstractThis paper provides an in-depth investigation of the possibility of systematically using flexemes – i.e., lexical units characterized in terms of form, as opposed to lexemes, characterized in terms of meaning – to model overabundance – i.e., the availability of more than one form in the same paradigm cell. The starting point is a preliminary evaluation of the advantages and disadvantages of using flexemes to account for different overabundance phenomena, showing that flexemes are a good way to capture the systematicity of overabundance, either across lexemes or across cells. Consequently, it is suggested that flexemes can be an interesting technical solution for the creation of a lexicon of Latin verbs that not only documents all the competing wordforms available as principal parts, but also captures the systematic relationship that sometimes holds between variants filling different cells. A principled method to identify such systematicity is then described in detail. It is argued that a constructive approach based on the identity of stems and/or inflection class is not fully adequate for the data at hand. Therefore, the proposed procedure adopts an abstractive, word-based perspective that only relies on alternation patterns between unsegmented wordforms. Practical and theoretical implications of the work are finally discussed, particularly regarding the usefulness of a formal approach to the identification of lexical units and paradigm cells.
Modelling Cell Orientation Under Stretch: The Effect of Substrate Elasticity
Authors: Colombi Annachiara , Preziosi Luigi , Scianna Marco 
Published: July 2023

AbstractWhen cells are seeded on a cyclically deformed substrate like silicon, they tend to reorient their major axis in two ways: either perpendicular to the main stretching direction, or forming an oblique angle with it. However, when the substrate is very soft such as a collagen gel, the oblique orientation is no longer observed, and the cells align either along the stretching direction, or perpendicularly to it. To explain this switch, we propose a simplified model of the cell, consisting of two elastic elements representing the stress fiber/focal adhesion complexes in the main and transverse directions. These elements are connected by a torsional spring that mimics the effect of crosslinking molecules among the stress fibers, which resist shear forces. Our model, consistent with experimental observations, predicts that there is a switch in the asymptotic behaviour of the orientation of the cell determined by the stiffness of the substratum, related to a change from a supercritical bifurcation scenario, whereby the oblique configuration is stable for a sufficiently large stiffness, to a subcritical bifurcation scenario at a lower stiffness. Furthermore, we investigate the effect of cell elongation and find that the region of the parameter space leading to an oblique orientation decreases as the cell becomes more elongated. This implies that elongated cells, such as fibroblasts and smooth muscle cells, are more likely to maintain an oblique orientation with respect to the main stretching direction. Conversely, rounder cells, such as those of epithelial or endothelial origin, are more likely to switch to a perpendicular or parallel orientation on soft substrates.

AbstractIt is known that a nevoid basal cell carcinoma syndrome (NBCCS) is characterized by a combination of developmental abnormalities and a predisposition to form various tumors. Although it is possible to create disease models via gene editing, there are significant potential problems with this approach such as off-target mutations and differences in SNPs. On the other hand, since disease families share common SNPs, research using iPSCs derived from both patients and healthy siblings of the same disease family is very important. Thus, establishment of induced pluripotent stem cells derived from patients and healthy siblings of the same NBCCS family will be of great importance to study the etiology of this disease and to develop therapeutics. In this study, we generated hiPSCs using peripheral blood mononuclear cells derived from the patients and healthy siblings of familial NBCCS with the novel mutation in PTCH1_c.3298_3299insAAG in the feeder- and serum-free culture conditions using SeVdp. In addition, disease-specific hiPSCs such as those expressing the PTCH1_c.3298_3299insAAG mutation could be powerful tools for revealing the genotype-phenotype relationship and pathogenicity of NBCCS.
Changes in the Nardus grasslands in the (Sub)Alpine Zone of Western Carpathians over the last decades
Authors: Palaj Andrej , Kollár Jozef , Michalová Martina 
Published: July 2023

AbstractNardus stricta dominated grassland is a specific habitat occurring on the nutrient-poor soils. Its large areas were formed as a result of livestock grazing. However, landscape management underwent significant changes over the last decades including grazing cessation. This triggered successional processes leading to considerable changes in floristic composition reported from numerous European regions. We focused on this phenomenon in the Western Carpathian high mountains, where the issue was not studied sufficiently. Our research, based on pairwise comparison of 19 historical and recent phytocoenological relevés, confirmed changes here. These include (i) decrease in cover of some diagnostic species of Nardetea strictae class, especially Nardus stricta, (ii) increase in competitively strong species with their high biomass productivity, (iii) shift in floristic composition indicating conversion of Nardion strictae vegetation into other communities, especially those of Loiseleurio-Vaccinietea class, (iv) increase in Shannon-Wiener index values and (v) enrichment of originally oligotrophic grasslands with some nutrient-demanding species, mainly at lower altitudes and decrease in light-demanding species.

Published: July 2023

AbstractSalinity stress is a major threat that negatively affects plant growth and production in arid and semi- arid regions. Application of biofertilizers could mitigate this stress. Accordingly, a pot experiment was conducted on rapeseed grown under salinity stress (0, 5, 10, and 15 dS m−1) while considering the following additives: (1) AMF (non-inoculated and inoculated with Glomus versiforme) and (2) PGPR (non-inoculated and inoculated with Micrococcus yunnanensis). The present results showed that salinity stress led to significant reductions in growth, yield, yield components, and physiological attributes, while raising the Na+/K+ ratio. However, with the application of PGPR and AMF, the increased salinity tolerance of rapeseed resulted in a significant improvement in redox status and ion homeostasis. They considerably improved antioxidant enzymatic activity and plant nutrition status. Furthermore, the co-inoculation of PGPR and AMF increased chlorophyll a, chlorophyll b, carotenoids, photosynthesis rate, and percentage of rapeseed oil under 15 dS m−1 1.7-, 1.8-, 2.3-, 2.0- and 1.3-times, respectively, compared with the non-inoculation treatment. These findings indicate that the integral application of PGPR and AMF is essential for alleviating salinity stress.

Published: July 2023

AbstractSecond-order (χ(2)) optical nonlinearity is one of the most common mechanisms for modulating and generating coherent light in photonic devices. Due to strong photon confinement and long photon lifetime, integrated microresonators have emerged as an ideal platform for investigation of nonlinear optical effects. However, existing silicon-based materials lack a χ(2) response due to their centrosymmetric structures. A variety of novel material platforms possessing χ(2) nonlinearity have been developed over the past two decades. This review comprehensively summarizes the progress of second-order nonlinear optical effects in integrated microresonators. First, the basic principles of χ(2) nonlinear effects are introduced. Afterward, we highlight the commonly used χ(2) nonlinear optical materials, including their material properties and respective functional devices. We also discuss the prospects and challenges of utilizing χ(2) nonlinearity in the field of integrated microcavity photonics.

AbstractThe performance of an outdoor pilot-scale system consisting of a high rate algal pond interconnected to an absorption bubble column and seeded with a microalgal-bacterial consortium is presented. Biogas and organic leachate (from food waste anaerobic hydrolysis) were used as sources of CO2 and nutrients for the consortium, respectively. The removal efficiencies for CO2 and H2S from biogas were 80.0% and 99.9%, respectively, provoking a methane content in the utilized biogas of approximately 55 vol% for anaerobically-produced biogas and 90 vol% for a prepared gaseous mixture. The molecular oxygen produced by microalgae photosynthesis induced undesirable cumulation of O2 in utilized biogas up to 5%vol. The organic leachate was diluted in an alkaline mineral medium (15:1 v/v), and this rich-nutrient mixture was fed to the system at a hydraulic retention time of 138 d. The biomass productivity applying organic leachate and anaerobically-produced biogas was 2.6 g m−3 d−1, nine times lower than biomass productivity achieved when only mineral salt medium was fed, suggesting the existence of limited nutrient bioavailability. Microalgal-bacterial community shifts evaluated through molecular and morphological methods showed that a robust and stable photosynthetic population was maintained throughout the entire operation of the system, formed mainly by Picochlorum sp., Pseudanabaena sp., Spirulina sp., and Nitzschia sp., as well as heterotrophic bacteria and some microalgae predators. The valued by-products after waste utilization were clean and highly calorific biogas besides microalgae biomass, where the commercialization of the latter would determine the economic viability of biogas and leachate utilization.

Do people believe that machines have minds and free will? Empirical evidence on mind perception and autonomy in machines
Authors: Astobiza Aníbal M. 
Published: July 2023

Abstract
Recently, we are witnessing an unprecedented advance and development in Artificial Intelligence (AI). AI systems are capable of reasoning, perceiving, and processing spoken (and written) natural language, and their applications vary from recommendation systems, automated translation software, prioritization of news in social media, to self-driving cars and/or robotics. A dystopian narrative predicts that AI may reach a point of singularity or a phase where machines surpass human beings in general intelligence and enslave us, but until that day comes, it is interesting to know how the general public perceive current artificial systems. Do people really attribute mind (i.e., mental states) and/or free will to artificial systems? Knowing how the general public perceive artificial systems is crucial because it could help understand how to apply AI in medicine, law, politics and other areas of human life. One study that I present here with a convenience sample (N = 25) suggests this is not the case. General public do not perceive artificial systems can have mind nor do they attribute free will to them (F (5,57), (dif1 1), (dif2 47,6), p < 0.002).
A blessing or a curse? Can digital economy development narrow carbon inequality in China?
Authors: Zhao Congyu , Wang Jianda , Dong Kangyin , Dong Xiucheng 
Published: July 2023

AbstractThe importance of carbon emissions reduction notwithstanding, the issue of its inequality should also elicit the urgent attention of scholars. This paper first evaluates the carbon inequality between urban and rural areas based on a panel dataset of 30 provinces in China from 2006 to 2019. Then we quantitively investigate the role of digital economy development in reducing carbon inequality. We further explore the possible moderating role of residential disposable income in the rural areas and the impact channels in the nexus between digital economy development and carbon inequality. We find that (1) the relationship between digital economy development and carbon inequality is negative, and digital economy development exerts a significant mitigating impact on carbon inequality. (2) The nexus between digital economy development and carbon inequality is heterogeneous in terms of capital: provinces endowed with lower levels of social and human capital tend to exhibit a stronger connection between digital economy development and carbon inequality. (3) Rural residential disposable income can not only reduce carbon inequality, but can also show a synergistic effect with digital economy development, which means the interaction between rural residential disposable income and digital economy development also restricts carbon inequality significantly. (4) Digital economy development works on carbon inequality by increasing environmental regulation and technology innovation, and these two channels show a mitigating impact on carbon inequality. We propose several policy implications to accelerate the reduction of carbon inequality and the improvement of digital economy development.
Assessing GPT-4’s role as a co-collaborator in scientific research: a case study analyzing Einstein’s special theory of relativity
Authors: Bryant Steven 
Published: July 2023

AbstractThis paper investigates GPT-4’s role as a research partner, particularly its ability to scrutinize complex theories like Einstein’s Special Relativity Theory (SRT). GPT-4’s advanced capabilities prove invaluable in complex research scenarios where human expertise might be limited. Despite initial biases, an inclination to uphold Einstein’s theory, and certain mathematical limitations, GPT-4 validated an inconsistency within the SRT equations, leading to a questioning of the theory's overall validity. GPT-4 contributed significantly to honing the analytical approach and expanding constraints. This paper explores the strengths and challenges associated with the use of GPT-4 in scientific research, with a strong emphasis on the need for vigilance concerning potential biases and limitations in large language models. The paper further introduces a categorization framework for AI collaborations, and specific guidelines for optimal interaction with advanced models like GPT-4. Future research endeavors should focus on augmenting these models’ precision, trustworthiness, and impartiality, particularly within complex or contentious research domains.

Published: July 2023

ABSTRACTIn much of the Western world, collaborative research undertaken by settler archaeologists readily lends itself, at least in part, to a continuation of the colonial project. Yet, against this backdrop, Australia's First Nations’ peoples continue to work with researchers and to drive systemic change in research practice. Community-engaged archaeology, defined here as codeveloped studies of ancestral places (following Schaepe et al. 2017), is directed to improving relationships between Indigenous peoples and archaeologists. Even so, the practice of archaeology with and for nonsettler communities remains underdeveloped with regard to institutional priorities and funding agency bureaucracies. Here, we (Mirarr Traditional Owners, Mirarr employees, and settler archaeologist researchers) reflect on these issues as part of our ongoing research on the ochres and bim (rock art) of the well-known Madjedbebe rockshelter in the Alligator Rivers region, Northern Territory, Australia.
Defending the Rights of Local Communities against Box-Ticking Exercises: An Analysis of Sustaining the Wild Coast NPC v Minister of Mineral Resources and Energy
Authors: Rankin Claire 
Published: July 2023

Abstract
This piece analyses the recent judgment from the Makhanda High Court in Sustaining the Wild Coast NPC v Minister of Mineral Resources and Energy setting aside the decision to grant Shell and Impact Africa an exploratory right. Shell and Impact Africa intended to conduct a seismic survey along South Africa’s Wild Coast. Such a survey stood to have a substantial impact on the rights and interests of several local communities residing along the coastline. Because Shell, Impact Africa and the Director-General of the Department of Mineral Resources and Energy failed to consider these rights and interests, the court decided to overturn the decision granting the companies their exploratory right. To this end, the judgment provides a powerful vindication of the rights of local communities, illustrating what is possible when regulatory schemes are applied purposively and not as a mere box-ticking exercise.
Quantum systems at the brink: existence of bound states, critical potentials, and dimensionality
Authors: Hundertmark Dirk , Jex Michal , Lange Markus 
Published: July 2023

Abstract
One of the crucial properties of a quantum system is the existence of bound states. While the existence of eigenvalues below zero, that is, below the essential spectrum, is well understood, the situation of zero energy bound states at the edge of the essential spectrum is far less understood. We present complementary sharp criteria for the existence and nonexistence of zero energy ground states. Our criteria give a straightforward explanation for the folklore that there is a spectral phase transition with critical dimension four, concerning the existence versus nonexistence of zero energy ground states.
The proactive nature of employee voice: The facilitating role of supervisor developmental feedback
Authors: Sibunruang Hataya , Kawai Norifumi 
Published: July 2023

AbstractDrawing upon Parker, Bindl, and Strauss' [(2010). Making things happen: A model of proactive motivation. Journal of Management, 36(4), 827–856] model of proactive motivation, we provide an explanation for how employees who exhibit a high need for achievement can take a proactive initiative through the expression of voice. Importantly, the extent to which employee voice can bring about desired changes depends largely on how positively received the behavior is by those in higher positions, such as supervisors. In this regard, we further highlight the facilitating role of supervisor developmental feedback in shaping the effectiveness of voice behavior. Data from 392 independently matched subordinate–supervisor dyads from Japan provide empirical support for proposed relationships as follows: (a) there is a positive mediating relationship between the need for achievement, employee voice, and supervisors' evaluations of employee task performance and discretionary work effort, and (b) the mediating relationship becomes stronger when supervisor developmental feedback is high. Theoretical and practical implications are further discussed.

AbstractWe introduceself-divisibleultrafilters, which we prove to be precisely those$w$such that the weak congruence relation$\equiv _w$introduced by Šobot is an equivalence relation on$\beta {\mathbb Z}$. We provide several examples and additional characterisations; notably we show that$w$is self-divisible if and only if$\equiv _w$coincides with the strong congruence relation$\mathrel {\equiv ^{\mathrm {s}}_{w}}$, if and only if the quotient$(\beta {\mathbb Z},\oplus )/\mathord {\mathrel {\equiv ^{\mathrm {s}}_{w}}}$is a profinite group. We also construct an ultrafilter$w$such that$\equiv _w$fails to be symmetric, and describe the interaction between the aforementioned quotient and the profinite completion$\hat {{\mathbb Z}}$of the integers.
Late Pleistocene Neanderthal exploitation of stable and mosaic ecosystems in northern Iberia shown by multi-isotope evidence

Published: July 2023

AbstractDuring the last glacial period, rapidly changing environments posed substantial challenges to Neanderthal populations in Europe. Southern continental regions, such as Iberia, have been proposed as important climatic “buffer” zones during glacial phases. Contextualising the climatic and ecological conditions Neanderthals faced is relevant to interpreting their resilience. However, records of the environments and ecosystems they exploited across Iberia exhibit temporal and spatial gaps in coverage. Here we provide new evidence for palaeotemperatures, vegetation structure, and prey herbivore ecology during the late Pleistocene (MIS 5–3) in northern Spain, by applying multiple stable isotope tracers (δ18O, δ13C, δ15N, δ34S) to herbivore skeletal remains associated with Neanderthal occupations at Axlor Cave, Bizkaia. The results show little change over time and indicate stable climatic conditions and ecosystems across different occupations. Large within-layer isotopic variability in nitrogen and sulphur suggests the presence of a mosaic environment and a variety of isotopic ecotones that were exploited by Neanderthals and their prey. We implement a combination of carbonate and phosphate δ18O measurements to estimate palaeotemperatures using a cost-effective workflow. We show that the targeted use of phosphate δ18O measurements to anchor summer peak and winter trough areas enables high-precision seasonal palaeoclimatic reconstructions.
