Background/objective:

Disclosing individual research results to participants is not standard practice. The return of individual research results to participants may increase recruitment, retention, and engagement in research. This study’s objective was to explore the preferences, expectations, and experiences of research participants receiving individual research results.

Methods:

A mixed-methods approach, consisting of semi-structured interviews and a health literacy assessment, was used with participants enrolled in a cohort study. The interviews were analyzed to produce an understanding of current experiences. Using descriptive analyses, responses were compared to identify alignments and divergences among participants.

Results:

Forty-three English-speaking and 16 Spanish-speaking participants enrolled. Ninety-eight percent of participants wanted to receive their individual research results. Seventy-five percent of participants reported they shared results with their healthcare providers. More participants aged 18–65 reported the need to follow up with their provider (70%) as compared to participants > 65 (20%). Two-thirds of participants reported a positive experience receiving their research results; however, 22% reported anxiety and worry. Most participants (69%) described the electronic medical record (EMR) as their preferred method for receiving their results. Yet only 50% of Spanish speakers preferred receiving research results through the EMR compared to 77% of English speakers. Participants with low health literacy preferred receiving study results in person or by phone.

Conclusion:

Research participants value receiving their individual research results, and this may increase recruitment and retention within the research enterprise. While more research is needed, the lessons learned from this study lay the groundwork for developing best practices and policies around the return of individual research results.
Low-cost tree crown dieback estimation using deep learning-based segmentation
Authors: Allen Matthew J. , Moreno-Fernández Daniel , Ruiz-Benito Paloma , Grieve Stuart W.D. , Lines Emily R.
Published: September 2024

The global increase in observed forest dieback, characterized by the death of tree foliage, heralds widespread decline in forest ecosystems. This degradation causes significant changes to ecosystem services and functions, including habitat provision and carbon sequestration, which can be difficult to detect using traditional monitoring techniques, highlighting the need for large-scale and high-frequency monitoring. Contemporary developments in the instruments and methods to gather and process data at large scales mean this monitoring is now possible. In particular, the advancement of low-cost drone technology and deep learning on consumer-level hardware provide new opportunities. Here, we use an approach based on deep learning and vegetation indices to assess crown dieback from RGB aerial data without the need for expensive instrumentation such as LiDAR. We use an iterative approach to match crown footprints predicted by deep learning with field-based inventory data from a Mediterranean ecosystem exhibiting drought-induced dieback, and compare expert field-based crown dieback estimation with vegetation index-based estimates. We obtain high overall segmentation accuracy (mAP: 0.519) without the need for additional technical development of the underlying Mask R-CNN model, underscoring the potential of these approaches for non-expert use and proving their applicability to real-world conservation. We also find that color-coordinate based estimates of dieback correlate well with expert field-based estimation. Substituting ground truth for Mask R-CNN model predictions showed negligible impact on dieback estimates, indicating robustness. Our findings demonstrate the potential of automated data collection and processing, including the application of deep learning, to improve the coverage, speed, and cost of forest dieback monitoring.
Impact of e-commerce development on rural income: Evidence from counties in revolutionary old areas of China
Authors: Wen Huwei , Qiu Anqi , Huang Yulin
Published: September 2024

Digital technology has enormous potential in rural revitalisation, thus providing impetus for improving the well-being of rural residents in underdeveloped areas. This study takes the policies of e-commerce in rural areas as an intervention in the development of e-commerce. It uses the panel data from 321 counties in the old revolutionary areas of China from 2003 to 2020 to empirically explore the impact of e-commerce development on the income of rural residents. Results show that e-commerce significantly improves the income and well-being of rural residents in old revolutionary areas. Propensity score matching and entropy balance matching are used to overcome group differences in covariate features, and the estimation results are consistently robust. In terms of mechanisms, e-commerce development increases per capita income in old revolutionary areas by promoting three aspects significantly: agricultural revitalisation, non-agricultural employment, and government support efforts. On the other hand, the heterogeneity analysis shows that e-commerce plays a diminishing role in increasing income in the eastern, central, and western regions.
Collaborative Governance Structures for Interoperability in the EU’s new data acts
Authors: Schneider Jens-Peter , Erny Johannes , Enderlein Franka
Published: September 2024

This contribution analyses the EU’s new data acts. Interoperability is a common denominator of the EU’s new data acts. This paper demonstrates that the new data acts provide various approaches or concepts of collaborative governance to regulate interoperability. Although the EU’s new data acts are far from a uniform governance concept, we detected certain institutional arrangements organising the collaboration between private self-regulatory bodies, other private stakeholders and public bodies to lay down rules for interoperability.
Competing Legal Futures – “Commodification Bets” All the Way From Personal Data to AI
Authors: Giraudo Marco , Fosch-Villaronga Eduard , Malgieri Gianclaudio
Published: September 2024

This Article explores the implications of Artificial Intelligence (AI)-driven innovation across sectors, highlighting the resulting legal uncertainties. Despite the transformative influence of AI in healthcare, retail, finance and more, regulatory responses to these developments are often contradictory, contributing to the opacity of the legal underpinnings of AI business. Our Article notes the common trend of commercializing AI tools amidst legal uncertainty, using innovative contractual solutions to secure claims. Over time, these innovations trigger overlooked legal conflicts, sometimes leading to outright bans on AI products due to negative impacts on some fundamental rights and democratic Governance. The core argument of our Article is that an over-reliance on co-regulatory strategies, such as those proposed by the European AI Act, exacerbates legal instability in emerging technological markets. This panorama creates an ’extended legal present’ when alternative legal expectations coexist, thus causing economic and political uncertainty that may elicit legal instability in the future. The concept of ’competing legal futures’ is introduced to illustrate how economic actors must bet on a legal future in the absence of guarantees that this future will materialize. To help analyze this complex narrative, we propose a theoretical framework for understanding legal, technological, and economic dynamics, highlighting anomalies in market exchanges within the co-regulatory model. Despite the focus on European developments, the practical and theoretical implications extend beyond the EU, making the Article relevant to a broader understanding of the legal-economic challenges posed by AI and digital innovation. We conclude by arguing for a course correction, proposing institutional diversification for resilient governance of legal innovation under uncertainty.
Who is generous and to whom? Generosity among Christians, Muslims, and atheists in the USA, Sweden, Egypt, and Lebanon
Authors: Hallin Nathalie , Moche Hajdi , Andersson Gerhard , Västfjäll Daniel
Published: September 2024

Are religious people more generous than non-religious people? If so, are they more generous in general or mainly to members of their religious ingroup (i.e., parochially generous)? Also, do levels of parochial generosity differ between Christians, Muslims, and atheists? This paper examined these questions by using a novel design of the Dictator Game, where participants in multiple rounds decided how much money to keep for themselves and give to three other players, of whom some information is revealed. Three studies (N = 1,719) with a Swedish sample, an American sample, and a sample from Egypt and Lebanon were conducted. We found that religious people were more generous compared to non-religious people when information about players’ religious affiliation was available, but not when it was not available. The results suggest that if religious people are more generous, this mainly occurs when religious information is salient. We also found evidence of parochial generosity among Christians, Muslims, and atheists as all three groups gave more to their religious ingroup than to both of their outgroups. However, Muslims seemed to differ from Christians and atheists by giving more to their ingroup than the other two groups gave to their respective ingroups in the USA and possibly in Sweden.
Understanding the Local Complexities in Land Law Reforms: The Case of Land Inalienability in Ethiopia, 1991–2018
Authors: Ayano Mekonnen Firew
Published: September 2024

Postcolonial governments often restrict the market alienability of land rights for various policy reasons. One policy aims to treat all citizens equivalently and safeguard vulnerable social communities equally, as an unrestrained land market could allow one affluent social group to buy out one that is less affluent. Another policy is to set a standard that is easy to apply in the same way in every case, as a bright-line rule banning land alienation is simpler to administer than a standard that requires case-by-case considerations. Today, in Ethiopia, such laws face opposition from proponents of a free market economy and private property rights. Thus, international development institutions and influential Ethiopians are spearheading an ambitious reform to Ethiopia’s post-socialist law that bans land alienability, arguing that the law has impeded social and economic progress. This article shows, however, that the legal ban has never prevented land transfers. Many people have utilized legal constructs such as gifts, bequests, loans, and leases to sell their land. Such transfers have circumvented the ban amidst aggressive land expropriation by the state and other agents. These intricate local and national dynamics undercut the misleading sense of regularity created by the inalienability law, raising serious questions about the persistent demand by international development institutions to privatize land rights and create land markets through law reform without paying close attention to the lived experiences at the local level.
The False Marking Gold Rush: A Case Study of the Private Enforcement of Public Laws
Authors: Clopton Zachary D.
Published: September 2024

Federal law prohibits deceiving the public by falsely marking an item as patented. The “false marking” prohibition has been enforced primarily by private lawsuits on behalf of the United States, with the party plaintiff and the government splitting the penalty. When a court decision dramatically increased the potential recovery for false marking claims, lawyers pounced immediately, filing more cases per week than had previously been filed in years. Indeed, many lawyers who did not previously work on patent cases joined the fray. Within two years, Congress eliminated this type of false marking suit and terminated all pending cases. Using empirical data, interviews with lawyers, legislative history, litigation documents, and news sources, this article tells the instructive history of false marking litigation. This history shows that the supply of private enforcement—lawsuits by private parties to enforce laws in the public interest—is sensitive to market forces. It also shows that, even when concentrated interests encourage Congress to cut back on private enforcement, Congress does not move as quickly as the bar. This matters because once Congress authorizes private enforcement, the maintenance of that system depends on judges and lawyers interpreting private enforcement statutes.
Belemnites of the family Belemnitellidae Pavlow, 1914 from the Late Cretaceous Maastrichtian stage in the Northern Hemisphere
Authors: Keutgen Norbert , Remin Zbyszek
Published: September 2024

The currently defined Global Stratotype Section and Point for the Campanian/Maastrichtian boundary at Tercis (France) lacks any belemnite record. However, the detailed correlation of Tercis with the Kronsmoor section in northern Germany has enabled recognising this boundary in terms of belemnite stratigraphy close to the first appearance datum (FAD) of Belemnella obtusa Schulz, 1979. Originally, the FAD of the genus Belemnella Nowak, 1913 (e.g. of Belemnella lanceolata (von Schlotheim, 1813)) has been widely used for defining the base of the traditionally understood Maastrichtian stage in the Boreal Realm. Belemnella appeared almost contemporaneously across a significant portion of epicontinental Europe in what is now considered topmost Campanian and dominated the lower Maastrichtian belemnite assemblages, co-occurring with Belemnitella d’Orbigny, 1840 and rare Fusiteuthis Kongiel, 1962. It disappeared in Western and Central Europe during the mid-Maastrichtian, and as a consequence, the FAD of Belemnitella junior Nowak, 1913 served as a biomarker defining the base of the upper Maastrichtian substage. It is only at the end of the Maastrichtian that the genus Neobelemnella Naidin, 1975 became abundant, replacing Belemnitella steadily from the east to the west as the dominating species. The factors underlying those remarkable shifts in belemnite assemblages remain uncertain, but various environmental elements, especially water depth and temperature, in addition ocean currents, and oceanic chemical composition are considered influential.
BIRATIONAL GEOMETRY OF SEXTIC DOUBLE SOLIDS WITH A COMPOUND

Published: September 2024

Sextic double solids, double covers of
$\mathbb P^3$
branched along a sextic surface, are the lowest degree Gorenstein terminal Fano 3-folds, hence are expected to behave very rigidly in terms of birational geometry. Smooth sextic double solids, and those which are
$\mathbb Q$
-factorial with ordinary double points, are known to be birationally rigid. In this paper, we study sextic double solids with an isolated compound
$A_n$
singularity. We prove a sharp bound
$n \leq 8$
, describe models for each n explicitly, and prove that sextic double solids with
$n> 3$
are birationally nonrigid.
The Breakdown of Effective Field Theory in Particle Physics: Lessons for Understanding Intertheoretic Relations
Authors: Koberinski Adam
Published: September 2024

Effective field theory (EFT) is a computationally powerful theoretical framework, finding application in many areas of physics. The framework, applied to the Standard Model of particle physics, is even more empirically successful than our theoretical understanding would lead us to expect. I argue that this is a problem for our understanding of how the Standard Model relates to some successor theory. The problem manifests as two theoretical anomalies involving relevant parameters: the cosmological constant and the Higgs mass. The persistent failure to fix these anomalies from within suggests that the way forward is to go beyond the EFT framework.
14C AMS measurement of CO2 samples with the high throughput HVE gas interface system
Authors: Scognamiglio G , Klein M , Stolz A , Walet R , Mous D
Published: September 2024

The newly designed HVE gas interface enables the AMS measurement of carbon samples in CO2 form. The CO2, e.g. resulting from the sample combustion in an elemental analyzer, is adsorbed in a zeolite trap and subsequently transferred to a motor-driven syringe. Once diluted with He, the gas mixture is transferred into the ion source of the AMS system. A carbon ion beam is formed in the ion source and mass-analyzed by the AMS system, resulting in 13C/12C and 14C/12C isotopic ratios. The HVE gas interface features two traps and two syringes to maximize the sample throughput, which results in more than 10 samples per hour. The first performance results of CO2 gas sample AMS measurements that were performed with the HVE gas interface in combination with the HVE 210 kV AMS system are presented in this paper. The measurements show that the gas interface contribution to the 14C/12C background is in the 10–15 level and to the precision is at or below 1%.
Dr Cooke’s Protest: Benjamin Cooke, Samuel Arnold, and the Directorship of the Academy of Ancient Music
Authors: WHITE BRYAN
Published: September 2024

In 1789, the Academy of Ancient Music replaced Benjamin Cooke with Samuel Arnold as its musical director. This article offers a detailed analysis of an autograph copy of the address Cooke delivered to the Academy responding to their action, and of a letter to Cooke from Arnold countering accusations made regarding his conduct in the affair. Both documents are annotated by Henry Cooke, who used them in writing a biography of his father. These documents enable a new understanding of the significant changes made within the Academy in the 1780s and of the reasons Academy subscribers replaced Cooke with Arnold.
ART, MIRACLES AND THE CULT OF THE VIRGIN AT THETFORD PRIORY: EVIDENCE FROM CAMBRIDGE, CORPUS CHRISTI COLLEGE MS 329
Authors: Reeve Matthew M
Published: September 2024

This essay explores two texts in a fifteenth-century manuscript from Thetford Priory, Norfolk (now ms 329 in the Parker Library, Corpus Christi College, Cambridge). The first is an account of Marian miracles leading to the building of the Lady Chapel in the thirteenth century, and the second is an account of the formation of its relic collection in the twelfth century, which would be housed inside a statue of the Virgin Mary. The destruction of Thetford Priory at the Dissolution lends them a special significance since they offer evidence of a minor Marian cult that would be otherwise lost to us. The texts also highlight the interactions of aristocratic patrons – the Bigod family – and their Cluniac foundation. This essay explores the texts for the first time, offers a transcription and translation of them and considers their place in the cult of the Virgin at Thetford and in England generally.
GRAVES’ CONCERNS: THE 1841–2 XANTHOS EXPEDITION
Authors: Wiltshire Roswyn
Published: September 2024

The expeditions removing and excavating antiquities at the site of Xanthos in Lycia (1841–4) have been highlighted by scholars as setting a new precedent for whole-sale collection from a single site, and the support – through the national museum and the Royal Navy – of the British government for archaeological endeavours. Questions remain, however, regarding the failure of the first mission to remove the antiquities. According to the current narrative, the blame rests on the navy officer assigned to support Charles Fellows. Based on archival research, this article presents the concerns that Commander Thomas Graves had with the undertaking. His perspective sheds new light on how ill-planned the initial attempts were, and consequently how much was learned. The obstacles encountered in the first Xanthos expedition spurred developments in archaeological practice, introduced by people of non-academic professions.
RIVER, GIANT AND HUBRIS: A NOTE ON VIRGIL, AENEID 8.330–2
Authors: Vuković Krešimir
Published: September 2024

Virgil has Evander trace the origins of the name of the river Tiber back to the death of a giant, called ‘Thybris’ (Aen. 8.330–2). This article argues that the reference to the violent (asper) giant can be understood as etymological wordplay on the Greek word hubris and as a potential allusion to the grammatical debate on the nature of aspiration. Varro's De gente populi Romani is identified as an important source for the characterization of the Tiber as a giant in primeval times. The political implications of the word hubris are also briefly explored with reference to various identities to which Evander alludes. The final part of the article argues that Theocritus’ Idyll 1 and the scholiast to Theocritus may have also inspired Virgil's description of the Tiber in this passage.
THE GUILT OF CADMUS THE FARMER IN STATIUS’ THEBAID
Authors: Criado Cecilia
Published: September 2024

Statius’ Thebaid inverts the traditional positive reading of agricultural work. In the account of the founding moments of Thebes, the poet remains faithful to what is documented in the extant Greek and Roman literary material. However, as this article argues, Statius introduces two significant innovations with respect to his thematic precedents. First, Cadmus the founder is explicitly and emphatically pointed out as guilty of the internecine struggle that results from his farming. Second, he does not limit himself to sowing the soil but, previously, he plows it. The ploughing motif, although pivotal in the myth of Jason's trials in Cholchis, only appears referred to Cadmus in Ovid's Metamorphoses (3.104–5), albeit in a very succinct form. As will be examined, Statius amplifies the Ovidian suggestion, programmatically conferring negative connotations to this motif (tillage, bull, yoke, furrow, etc.) throughout his epic. Cadmus’ ill-fated tillage is unambiguously presented as the origin of the curse of Thebes and as the root cause of the present fratricidal war between Eteocles and Polynices. The dire fruits which agricultural labour invariably produces in the Cadmean farmlands echo Lucanean Thessalian fields from whose furrows, contaminated by the blood of Roman combatants, grow polluted crops. The blame that Statius places on the shoulders of Cadmus the farmer, the relationship he establishes between farming and fratricidal war, and his insistence on the perverse effects of agricultural work transform mythic Thebes into an exemplar of fratricidal Rome as apt as Lucan's historical Thessaly.
THE BONES OF TIBULLUS: OVID, AMORES 3.9.59
Authors: Gervais Kyle
Published: September 2024

This article argues for an emendation to Ovid, Amores 3.9, Ovid's lament for Tibullus. The transmitted text of line 59 would seem to present a contradiction: Ovid speculates about aliquid nisi nomen et umbra surviving death, and then proceeds in the next few lines to identify that aliquid as, precisely, Tibullus’ umbra. Ovid's original text was most likely aliquid nisi nomen et ossa, referring to a burial site and funerary inscription; with this text, Ovid reproduces details from Tibullus 1.3, a poem which he reworks throughout his elegy.

Plato, Republic 606ab, which deals with the soul bipartition and the behaviour of the two soul components during a theatrical performance, has been the object of scholarly dispute concerning both its grammar and its meaning. This article proposes a new syntactical approach and argues that the passage does not have to be interpreted as contradicting the context.
Drought responses in Coffea arabica as affected by genotype and phenophase. II – photosynthesis at leaf and plant scales
Authors: Rakocevic Miroslava , Costes Evelyne , Campostrini Eliemar , Ramalho José Cochicho , Ribeiro Rafael Vasconcelos
Published: September 2024

The aim of this work was to compare gas exchanges from leaf to whole plant scales, in two Ethiopian accessions (‘E083’ and ‘E027’), and two bred cultivars (Iapar 59 and Catuaí 99) of Arabica coffee (Coffea arabica L.) cultivated under irrigated and rainfed conditions. Variations in gas exchanges were evaluated over four phenophases (leaf expansion – BE1 and BE2, and berry harvesting – BH1 and BH2), covering the first two production years in the coffee life cycle. We addressed the following questions: Are gas exchanges modified by water availability at leaf and/or plant scales? Do bred cultivars and wild accessions differ in their physiological responses to water availability and phenophases? Photosynthesis (A), stomatal conductance (gs), and transpiration (E) were measured on the recently fully expanded leaves at the upper canopy stratum. The functional-structural plant modelling (FSPM) was used to integrate A at whole plant photosynthesis (A”p), based on 3D virtual trees constructed under VPlants modelling platform. Despite high A values of ‘E083’ overall phenophases, a strong decline in A”p under rainfed condition was observed due to lower plant leaf area as compared to irrigated condition. Catuaí 99 and ‘E083’ were more sensitive to drought than Iapar 59 and ‘E027’, considering photosynthesis at leaf and plant scales. At the last BH2 phenophase, A, gs, E, and carboxylation efficiency were similar between irrigated and rainfed conditions for all genotypes, suggesting some acclimation of leaf gas exchange to the environment. However, A”p benefited by water management in all phenophases as plant leaf area increased. These findings revealed the need to develop methodologies for structural and functional analyses at plant scale, an important step towards the realistic responses of plants and orchards to the surrounding environment.
Clerical Professionalisation and Catholic Enlightenment in the Polish-Lithuanian Commonwealth
Authors: WITECKI STANISŁAW
Published: September 2024

The article evaluates clerical professionalisation in the eighteenth-century Polish-Lithuanian Commonwealth by examining the division of labour within parishes. It argues that proponents of the Catholic Enlightenment endeavoured to achieve post-Tridentine reforms while also assigning to the clerical profession responsibilities for the material well-being of parishioners and service to the Commonwealth. It concludes that the process of clerical professionalisation remained incomplete. Firstly, approval for hiring assistant priests resulted in the delegation of many, if not all, ecclesiastical duties to them. Secondly, the improved professional education of priests occasionally led to unexpected withdrawal from pastoral duties seen as falling below their acquired competencies.
The Significance of Narrative in Cyril of Alexandria's Exegesis
Authors: STEEN AUSTIN
Published: September 2024

Scholars have rightly identified the roles of literal/historical interpretation and noetic/spiritual interpretation in Cyril of Alexandria's exegesis of Scripture. This article argues that narrative contributes to both methods by using events in the past to explain Scripture's meaning. He applies concepts established historically by Exodus’ recount of the Israelites’ presence in Egypt to his interpretation of the prophetic books. On the one hand, his literal interpretation draws from the Israelites’ return to idolatry, detailed in Exodus xxxii. On the other hand, his noetic interpretation relates the Egyptians’ oppression of the Israelites detailed in Exodus i to humanity's limitations under the devil.
John Wesley and Celibacy: Evolving Visions and Commitments
Authors: CAMPBELL TED A.
Published: September 2024

This article describes John Wesley's evolving visions of Christian singleness (celibacy) and three commitments related to his changing views: a commitment to celibacy in an Oxford college; a commitment to marriage with Mary Vazeille; a de facto commitment to single life after Mary's separation from him. Protestant Churches lacked structures to support celibate commitment, structures that might have discouraged his unguarded and intimate correspondence with married women that lay behind his separation from Mary. The article asks why Protestants, although formally allowing single life, have not found ways to honour commitments to it.
Imsharria orangei (Ascomycota, Lecideaceae), a new genus and species, and a new species of Porpidia, from the Falkland Islands
Authors: Fryday Alan M. , Götz Anna M. , Ruprecht Ulrike
Published: September 2024

The new genus Imsharria is proposed for a crustose species found on or near mountain summits on the Falkland Islands. It is separated from other genera of Lecideaceae by a combination of Porpidia-type asci, halonate ascospores, immersed apothecia and a hyaline hypothecium, and forms a distinct branch in the phylogenetic analysis using the markers nrITS and mtSSU. The single species, I. orangei, is characterized by its innate apothecia with a brown disc and a thallus containing norstictic acid and an amyloid (I+ violet) medulla. In addition, Porpidia imshaugii is described for a species from the Falkland Islands resembling P. skottsbergiana but with larger ascospores, and Porpidia navarina is shown to belong in the genus Poeltiaria, with the new combination Poeltiaria navarina being made. A key to the Lecideaceae on the Falkland Islands is provided.
Did the COVID-19 pandemic fuel public support for social protection?
Authors: Kim Taesim
Published: September 2024

Since the onset of the COVID-19 pandemic, both viral infection and the corresponding economic turmoil have wreaked havoc across the globe, highlighting the imperative function of the state as a social protection provider. The pandemic has seemingly created favourable political circumstances for rapidly expanding social protection, but its influences on public welfare attitudes remain unclear. In this study, I argue that the impact of pandemic-driven economic risk is too limited to spur strong public support for social protection. The employed empirical analyses using panel data collected in South Korea show that unemployment induced by the pandemic is conducive to higher degrees of individual support for social protection measures, but the impact is only short-lived. Further analyses show that, once individuals are re-employed and as the time spent in economic difficulties becomes more distant, personal unemployment experiences are no longer positively associated with support for social protection. Finally, pandemic-induced unemployment experiences have a lasting impact primarily on young adults. The evidence therefore suggests that significant institutional changes in the welfare state are hard to achieve by solely relying on the impact of economic risk.
NECROMANCY IN RENAISSANCE ROME
Authors: Gwynne Paul
Published: September 2024

Florence, Bibliotheca Riccardiana MS 996 is an interesting miscellany of late fifteenth- and early sixteenth-century texts. Among the manuscript's curious content is Dominici Cerbonii Tifernatis TERtheus Magus (‘The Triple God Magus of Domenico Cerbonio from Città di Castello’, fols 7r–10v). Evenly written in a neat humanistic cursive, with rubrication for the titles and a single marginal note (interpreted here as a stage direction), these folios form an account, in Latin prose and verse, of a necromantic ritual performed by members of the Roman Academy in which the shades of Cicero and Virgil are conjured from the pagan underworld to admire the Renaissance city. It is tempting to take this pagan rite as proof of the charges of heresy levelled at members of the Academy for which they were arrested and imprisoned in Castel Sant'Angelo on the orders of Pope Paul II Barbo (r. 1464–71) during Lent, 1468. However, this paper argues that the texts are evidence of a dramatic performance with scenery (or at least a theatrical backdrop) staged by the members of the reformed Academy as part of their annual celebrations of the Palilia (or Parilia) on Rome's birthday 21 April c. 1501.
MonoVisual3DFilter: 3D tomatoes’ localisation with monocular cameras using histogram filters
Authors: Magalhães Sandro Augusto Costa , dos Santos Filipe Neves , Moreira António Paulo , Dias Jorge Manuel Miranda
Published: September 2024

Performing tasks in agriculture, such as fruit monitoring or harvesting, requires perceiving the objects’ spatial position. RGB-D cameras are limited under open-field environments due to lightning interferences. So, in this study, we state to answer the research question: “How can we use and control monocular sensors to perceive objects’ position in the 3D task space?” Towards this aim, we approached histogram filters (Bayesian discrete filters) to estimate the position of tomatoes in the tomato plant through the algorithm MonoVisual3DFilter. Two kernel filters were studied: the square kernel and the Gaussian kernel. The implemented algorithm was essayed in simulation, with and without Gaussian noise and random noise, and in a testbed at laboratory conditions. The algorithm reported a mean absolute error lower than 10 mm in simulation and 20 mm in the testbed at laboratory conditions with an assessing distance of about 0.5 m. So, the results are viable for real environments and should be improved at closer distances.
Artificial neural network-based control of powered knee exoskeletons for lifting tasks: design and experimental validation
Authors: Arefeen Asif , Xiang Yujiang
Published: September 2024

This study introduces a hybrid model that utilizes a model-based optimization method to generate training data and an artificial neural network (ANN)-based learning method to offer real-time exoskeleton support in lifting activities. For the model-based optimization method, the torque of the knee exoskeleton and the optimal lifting motion are predicted utilizing a two-dimensional (2D) human–exoskeleton model. The control points for exoskeleton motor current profiles and human joint angle profiles from cubic B-spline interpolation represent the design variables. Minimizing the square of the normalized human joint torque is considered as the cost function. Subsequently, the lifting optimization problem is tackled using a sequential quadratic programming (SQP) algorithm in sparse nonlinear optimizer (SNOPT). For the learning-based approach, the learning-based control model is trained using the general regression neural network (GRNN). The anthropometric parameters of the human subjects and lifting boundary postures are used as input parameters, while the control points for exoskeleton torque are treated as output parameters. Once trained, the learning-based control model can provide exoskeleton assistive torque in real time for lifting tasks. Two test subjects’ joint angles and ground reaction forces (GRFs) comparisons are presented between the experimental and simulation results. Furthermore, the utilization of exoskeletons significantly reduces activations of the four knee extensor and flexor muscles compared to lifting without the exoskeletons for both subjects. Overall, the learning-based control method can generate assistive torque profiles in real time and faster than the model-based optimal control approach.
Customized stiffness control strategy for a six-bar linkage-based gait rehabilitation robot
Authors: Kapsalyamov Akim , Hussain Shahid , Goecke Roland , Brown Nicholas A.T. , Jamwal Prashant K.
Published: September 2024

Lower limb rehabilitation robots based on linkage-based mechanisms have recently drawn significant attention in the field due to their numerous advantages. The control of previously proposed linkage-based gait rehabilitation robotic orthoses has been achieved using constant speed control without consideration for the interaction forces. However, such an approach can be harmful to people with stroke since the level of disability varies among individuals, and it may cause potential injuries when excessive force is applied by the robot. To overcome this limitation and improve the rehabilitation process, it is necessary to recognize the force exerted by the person during walking and adjust the robot’s assistive torque accordingly, to provide synchronized motion. Thus, in this work, a human-cooperative approach based on a stiffness control strategy for the six-bar linkage-based gait rehabilitation robot is presented. The proposed methodology can serve as a solid foundation for developing a human-cooperative approach for linkage-based lower limb rehabilitation robotic orthoses. The control was validated and tested with eight healthy human subjects. As a result, customized robotic assistance with this mechanism can be provided during training to meet the individual needs of stroke patients, which can lead to increased engagement and contribution, thus improving treatment outcomes.
Structural priming facilitates L2 learning of the dative alternation in Mandarin
Authors: Zhu Yanxin (Alice) , Grüter Theres
Published: September 2024

This study investigated whether structural priming, as a reflection of error-driven learning mechanisms, could facilitate second language (L2) learning of the dative alternation in Mandarin. We sought evidence of learning from both priming and acceptability judgment data. Participants were 25 native speakers and 41 classroom learners (CLs). After a priming session in which participants predicted and then saw what a virtual partner had written to describe pictures (prime trials, with only acceptable verb-dative pairings), CLs showed increased production of these acceptable pairings and increased acceptability ratings for them. The observation of such longer-term priming effects beyond the priming phase, together with an inverse frequency effect of priming observed among the CLs, aligns well with error-driven learning accounts. However, we did not find evidence for statistical preemption, in that participants did not decrease ratings for unacceptable pairings as a result of exposure to their competing alternatives.

The last three decades have seen significant development in understanding and describing the effects of task complexity on learner internal processes. However, researchers have primarily employed behavioral methods to investigate task-generated cognitive load. Being the first to adopt neuroimaging to study second language (L2) task effects, we aimed to provide novel insights into the neural correlates of task-related variation in L2 oral production. To advance research methodology, we also tested the utility of a neuroimaging technique, functional magnetic resonance imaging (fMRI), in examining the impact of task-related variables on L2 speech production when combined with cognitive–behavioral tools (speech analysis, expert and learner judgments). Our research focus was the effects of task complexity on silent pausing. Twenty-four Japanese learners of English completed eight simple and complex versions of decision-making tasks, half in their first language and half in their L2. The dataset for the present study included the L2 speech and fMRI data, expert judgments, and participants’ difficulty ratings of the L1 and L2 tasks they completed. Based on our findings, we concluded that brain imaging and L1 task difficulty ratings were more sensitive to detecting task complexity effects than L2 self-ratings and pausing measures. These results point to the benefits of triangulating cognitive and neural data to study task-based neurocognitive processes.

Surface roughness is a critical factor affecting the performance of dental implants. One approach to influence this is through sandblasted, large grit, acid-etched (SLA) modification on pure titanium implant surfaces. In this study, SLA was performed on grade IV pure titanium. Sandblasting was conducted at distances of 2, 4, and 6 cm. Subsequently, the samples were etched with a mixed acid solution of HCl, H2SO4, and H2O for 0, 30, and 60 min. Surface roughness and X-ray diffraction (XRD) characterizations were conducted on the samples. The results revealed that surface roughness increased but was not too significant as the sandblasting distance decreased. Longer etching durations for sandblasted with acid-etched samples led to reduced surface roughness (Sa and Sz). It was found that a 60 min-etched sample resulted in optimal Sa, Sz, and Ssk values, i.e., 1.19 μm, 13.76 μm, and −0.60, respectively. The XRD texture was significantly influenced by sandblasting, with compressive residual stress increasing as the sandblasting distance decreased. Normal stress causes hill formations at shorter sandblasting distances. For etched samples, the residual stress decreased with longer etching durations. Normal stress-decreasing trend aligns with the initial reduction in hill and valley within the samples and subsequent hill enhancement at extended etching duration.

Published: September 2024

This paper is concerned with the development and analysis of a mathematical model that is motivated by interstitial hydrodynamics and tissue deformation mechanics (poro-elasto-hydrodynamics) within an in-vitro solid tumour. The classical mixture theory is adopted for mass and momentum balance equations for a two-phase system. A main contribution of this study is we treat the physiological transport parameter (i.e., hydraulic resistivity) as anisotropic and heterogeneous, thus the governing system is strongly coupled and non-linear. We derived a weak formulation and then formulated the equivalent fixed-point problem. This enabled us to use the Galerkin method, and the classical results on monotone operators combined with the well-known Schauder and Banach fixed-point theorems to prove the existence and uniqueness of results.
The Beginning of Time
Authors: Overmann Karenleigh A.
Published: September 2024

The present analysis focuses on the material component of time, the devices used for measuring and counting it. The biological basis for subjective, experiential time is first reviewed, as are early strategies found cross-culturally for measuring and counting time objectively. These strategies include timekeeping by natural phenomena, using tallies to keep track of small periods of time, harnessing shadows for daily and annual time, and visualizing time with clocks and calendars. The conclusion then examines how such timekeeping devices might influence the conceptualization of time.
The role of microRNAs in the regulation of critical genes and signalling pathways that determine endometrial receptivity

Endometrial receptivity is the ability of the endometrium to accept embryos. Thus, endometrial receptivity dysfunction is an important factor leading to embryo implantation failure. A good endometrial receptivity provides a suitable environment for embryo implantation, improving the embryo implantation rate. The “implantation window” stage, or the receptive stage of the endometrium, is regulated by various hormones, genes, proteins and cytokines, among which microRNAs (miRNAs) and their target genes have a regulatory effect on endometrial receptivity. This review outlines the relationship between endometrial receptivity and pregnancy, the mRNAs and related signalling pathways that regulate endometrial receptivity, and the regulatory role of miRNA in endometrial receptivity, providing a deeper understanding of the regulatory mechanisms of miRNA on endometrial receptivity in humans and animals and reference for the endometrial receptivity-related research.

Objectives:

Identify which NIH Toolbox Cognition Battery (NIHTB-CB) subtest(s) best differentiate healthy controls (HC) from those with amnestic mild cognitive impairment (aMCI) and compare the discriminant accuracy between a model using a priori “Norm Adjusted” scores versus “Unadjusted” standard scores with age, sex, race/ethnicity, and education controlled for within the model. Racial differences were also examined.

Methods:

Participants were Black/African American (B/AA) and White consensus-confirmed (HC = 96; aMCI = 62) adults 60–85 years old that completed the NIHTB-CB for tablet. Discriminant function analysis (DFA) was used in the Total Sample and separately for B/AA (n = 80) and White participants (n = 78).

Results:

Picture Sequence Memory (an episodic memory task) was the highest loading coefficient across all DFA models. When stratified by race, differences were noted in the pattern of the highest loading coefficients within the DFAs. However, the overall discriminant accuracy of the DFA models in identifying HCs and those with aMCI did not differ significantly by race (B/AA, White) or model/score type (Norm Adjusted versus Unadjusted).

Conclusions:

Racial differences were noted despite the use of normalized scores or demographic covariates—highlighting the importance of including underrepresented groups in research. While the models were fairly accurate at identifying consensus-confirmed HCs, the models proved less accurate at identifying White participants with an aMCI diagnosis. In clinical settings, further work is needed to optimize computerized batteries and the use of NIHTB-CB norm adjusted scores is recommended. In research settings, demographically corrected scores or within model correction is suggested.
