Towards Visual Semantics
Authors: Giunchiglia Fausto , Erculiani Luca , Passerini Andrea 
Published: September 2021

AbstractLexical Semanticsis concerned with how words encode mental representations of the world, i.e.,concepts. We call this type of concepts,classification concepts. In this paper, we focus onVisual Semantics, namely, on how humans build concepts representing what they perceive visually. We call this second type of concepts,substance concepts. As shown in the paper, these two types of concepts are different and, furthermore, the mapping between them is many-to-many. In this paper we provide a theory and an algorithm for how to build substance concepts which are in a one-to-one correspondence with classifications concepts, thus paving the way to the seamless integration between natural language descriptions and visual perception. This work builds upon three main intuitions: (i) substance concepts are modeled asvisual objects, namely, sequences of similar frames, as perceived in multipleencounters; (ii) substance concepts are organized into avisual subsumption hierarchybased on the notions of and ; (iii) the human feedback is exploitednotto name objects, but, rather, to align the hierarchy of substance concepts with that of classification concepts. The learning algorithm is implemented for the base case of a hierarchy of depth two. The experiments, though preliminary, show that the algorithm manages to acquire the notions of and with reasonable accuracy, this despite seeing a small number of examples and receiving supervision on a fraction of them.
Social behavior prediction with graph U-Net+
Authors: Yan Zhiyue , Cao Wenming , Ji Jianhua 
Published: September 2021

AbstractWe focus on the problem of predicting social media user’s future behavior and consider it as a graph node binary classification task. Existing works use graph representation learning methods to give each node an embedding vector, then update the node representations by designing different information passing and aggregation mechanisms, like GCN or GAT methods. In this paper, we follow the fact that social media users have influence on their neighbor area, and extract subgraph structures from real-world social networks. We propose an encoder–decoder architecture based on graph U-Net, known as the graph U-Net+. In order to improve the feature extraction capability in convolutional process and eliminate the effect of over-smoothing problem, we introduce the bilinear information aggregator and NodeNorm normalization approaches into both encoding and decoding blocks. We reuse four datasets from DeepInf and extensive experimental results demonstrate that our methods achieve better performance than previous models.
The late ascent of Darwin's Descent: exploring human evolution and women's role for a new China, 1927–1965
Authors: Jiang Lijing 
Published: September 2021

AbstractDarwin's ideas held sway among Chinese intellectuals by the early twentieth century. Yet the usual emphasis was a Spencerism instead of Darwin's original ideas. As a result, translations of The Descent of Man in the early twentieth century quickly fell into oblivion. When the embryologist Zhu Xi (1900–62) eventually decided to give all evolutionary theories a comprehensive examination, he nevertheless found the idea of sexual evolution inadequate, as expressed in his volume Biological Evolution (1958). Only in the 1950s did serious efforts to translate Descent gather momentum, thanks to eugenicist and sociologist Pan Guangdan (1899–1967). Such efforts were not only responses to a renewed interest in Darwinism under the socialist regime, but also expressions that synthesized both scholars’ earlier paths in wrestling with schemes of human evolution and the roles of women in China's survival and renewal. Trained in different scientific and cultural milieus and holding almost oppositional views, the two scholars nevertheless converged in finding new meanings in Darwin's Descent.
How many minors are participating in clinical research today? An estimate and important lessons learned
Authors: Ittenbach Richard F. , Corsmo Jeremy J. , Kissling Alison D. , Strauss Arnold W. 
Published: September 2021

Abstract
Little is known about the number of minors enrolled in clinical research today. IRB administrators at leading pediatric medical centers were surveyed regarding studies with minors. Analyses were descriptive in nature with adaptive Bayesian bootstrap imputation used with missing data. Officials from 17/41 (41.5%) pediatric research centers responded: 74,204 active studies were estimated, 29,078 (39%) included minors, and 6574 (23%) were “more than minimal risk.” Minors accounted for 0.7–2.87M research subjects. Pediatric medicine desperately needs a more accurate and reliable reporting system for tracking the recruitment, retention, and involvement of minors in clinical research.
Emulating computer experiments of transport infrastructure slope stability using Gaussian processes and Bayesian inference

Published: September 2021

AbstractWe propose using fully Bayesian Gaussian process emulation (GPE) as a surrogate for expensive computer experiments of transport infrastructure cut slopes in high-plasticity clay soils that are associated with an increased risk of failure. Our deterioration experiments simulate the dissipation of excess pore water pressure and seasonal pore water pressure cycles to determine slope failure time. It is impractical to perform the number of computer simulations that would be sufficient to make slope stability predictions over a meaningful range of geometries and strength parameters. Therefore, a GPE is used as an interpolator over a set of optimally spaced simulator runs modeling the time to slope failure as a function of geometry, strength, and permeability. Bayesian inference and Markov chain Monte Carlo simulation are used to obtain posterior estimates of the GPE parameters. For the experiments that do not reach failure within model time of 184 years, the time to failure is stochastically imputed by the Bayesian model. The trained GPE has the potential to inform infrastructure slope design, management, and maintenance. The reduction in computational cost compared with the original simulator makes it a highly attractive tool which can be applied to the different spatio-temporal scales of transport networks.

Published: September 2021

AbstractPaleobiological and paleoecological interpretations rely on constraining the temporal resolution of the fossil record. The taphonomic clock, that is, a correlation between the alteration of skeletal material and its age, is an approach for quantifying time-averaging scales. We test the taphonomic clock hypothesis for marine demersal and pelagic fish otoliths from a 10–40 m depth transect on the Mediterranean siliciclastic Israeli shelf by radiocarbon dating and taphonomic scoring. Otolith ages span the last ~8000 yr, with considerable variation in median and range along the transect. Severely altered otoliths, contrary to pristine otoliths, are likely to be older than 1000 yr. For pelagic fish otoliths, at 30 m depth, taphonomic degradation correlates positively with postmortem age. In contrast, no correlation occurs for demersal fishes at 10 and 30 m depth, mostly because of the paucity of very young pristine (<150 yr) otoliths, possibly due to a drop in production over the last few centuries. Contrary to molluscan and brachiopod shells, young otoliths at these depths are little affected and do not show a broad spectrum of taphonomic damage, because those that derive from predation are excreted in calcium- and phosphate-rich feces forming an insoluble crystallic matrix that increases their preservation potential. At 40 m depth, all dated otoliths are very young but rather damaged because of locally chemically aggressive sediments, thus showing no correlation between taphonomic grade and postmortem age. Our results show that local conditions and the target species population dynamics must be considered when testing the taphonomic clock hypothesis.

AbstractThe GaLactic and Extragalactic All-sky Murchison Widefield Array (GLEAM) is a radio continuum survey at 76–227 MHz of the entire southern sky (Declination$<\!{+}30^{\circ}$) with an angular resolution of${\approx}2$arcmin. In this paper, we combine GLEAM data with optical spectroscopy from the 6dF Galaxy Survey to construct a sample of 1 590 local (median$z \approx 0.064$) radio sources with$S_{200\,\mathrm{MHz}} > 55$mJy across an area of${\approx}16\,700\,\mathrm{deg}^{2}$. From the optical spectra, we identify the dominant physical process responsible for the radio emission from each galaxy: 73% are fuelled by an active galactic nucleus (AGN) and 27% by star formation. We present the local radio luminosity function for AGN and star-forming (SF) galaxies at 200 MHz and characterise the typical radio spectra of these two populations between 76 MHz and${\sim}1$GHz. For the AGN, the median spectral index between 200 MHz and${\sim}1$GHz,$\alpha_{\mathrm{high}}$, is$-0.600 \pm 0.010$(where$S \propto \nu^{\alpha}$) and the median spectral index within the GLEAM band,$\alpha_{\mathrm{low}}$, is$-0.704 \pm 0.011$. For the SF galaxies, the median value of$\alpha_{\mathrm{high}}$is$-0.650 \pm 0.010$and the median value of$\alpha_{\mathrm{low}}$is$-0.596 \pm 0.015$. Among the AGN population, flat-spectrum sources are more common at lower radio luminosity, suggesting the existence of a significant population of weak radio AGN that remain core-dominated even at low frequencies. However, around 4% of local radio AGN have ultra-steep radio spectra at low frequencies ($\alpha_{\mathrm{low}} < -1.2$). These ultra-steep-spectrum sources span a wide range in radio luminosity, and further work is needed to clarify their nature.

AbstractIn different parts of the world, aphid populations and their natural enemies are influenced by landscapes and climate. In the Neotropical region, few long-term studies have been conducted, maintaining a gap for comprehension of the effect of meteorological variables on aphid population patterns and their parasitoids in field conditions. This study describes the general patterns of oscillation in cereal winged aphids and their parasitoids, selecting meteorological variables and evaluating their effects on these insects. Aphids exhibit two annual peaks, one in summer–fall transition and the other in winter-spring transition. For parasitoids, the highest annual peak takes place during winter and a second peak occurs in winter–spring transition. Temperature was the principal meteorological regulator of population fluctuation in winged aphids and parasitoids during the year. The favorable temperature range is not the same for aphids and parasitoids. For aphids, temperature increase resulted in population growth, with maximum positive effect at 25°C. Temperature also positively influenced parasitoid populations, but the growth was asymptotic around 20°C. Although rainfall showed no regulatory function on aphid seasonality, it influenced the final number of insects over the year. The response of aphids and parasitoids to temperature has implications for trophic compatibility and regulation of their populations. Such functions should be taken into account in predictive models.
The First Earl of Shaftesbury's Resolute Conscience and Aristocratic Constitutionalism
Authors: Mansfield Andrew 
Published: September 2021

AbstractThis article provides a reappraisal of the first earl of Shaftesbury (1621–83) and challenges his reputation as an unprincipled politician. Conversely, it is argued that Shaftesbury's opposition to both Cromwell during the Protectorate and Charles II in the Restoration was guided by a resolute ‘conscience’. While there was certainly elasticity in his conduct, Shaftesbury was very much the product of a political education framed during the Civil War and Commonwealth eras. The article explicitly demonstrates through an exposition of his activity and thought in the 1650s and 1670s that four guiding values remained consistent in his career. Both periods were shaped by concerns over political and religious tyranny by an overbearing executive and a threat to ‘lives, liberty, and property’ from the ruler, the church, and the army. Shaftesbury's significance lies in the aristocratic constitutionalism he believed offered a restraint to encroachment by the executive and the people in government. Relying upon long-established traditions that positioned the nobility as an independent bridle against arbitrary government, Shaftesbury suggested a forward-thinking vision of elite rule supported by the people. In clarifying Shaftesbury's values, the article rejects interpretations of him as a republican, Neo-Harringtonian, or a believer in popular government (democracy).
More than Beast: Muhammad's She-Mule Duldul and Her Role in Early Islamic History
Authors: Marashi Taryn 
Published: September 2021

AbstractDuldul, a beloved she-mule of the Prophet Muhammad and ʿAli b. Abi Talib (d. 661), fourth caliph and Muhammad's son-in-law, was a venerated riding beast in early Islamic tradition. The article argues that Duldul reflected the transmission of political authority and became a tool of legitimation for hadith compilers and medieval Muslim writers to use, contest, and navigate an emergent Shiʿa-Sunni rift. Exploring the responsive relationship between hadith construction and the Shiʿa-Sunni polemic, the article first analyzes three literary genres—maghāzī, hadith, and sīra—to describe Duldul and her role in early Islamic history. Second, the article examines the writings of al-Jahiz (d. 868) and al-Damiri (d. 1405) to understand medieval Muslim attitudes toward Duldul and she-mules in general. By taking Duldul more seriously as a historical actor, we can gain deeper insight into the disputes over Muhammad's legacy in medieval Islam.

AbstractBackgroundDeficits in event-related potential (ERP) including duration mismatch negativity (MMN) and P3a have been demonstrated widely in chronic schizophrenia (SZ) but inconsistent findings were reported in first-episode patients. Psychotropic medications and diagnosis might contribute to different findings on MMN/P3a ERP in first-episode patients. The present study examined MMN and P3a in first episode drug naïve SZ and bipolar disorder (BPD) patients and explored the relationships among ERPs, neurocognition and global functioning.MethodsTwenty SZ, 24 BPD and 49 age and sex-matched healthy controls were enrolled in this study. Data of clinical symptoms [Positive and Negative Symptoms Scale (PANSS), Young Manic Rating Scale (YMRS), Hamilton Depression Rating Scale (HAMD)], neurocognition [Wechsler Adult Intelligence Scale (WAIS), Cattell's Culture Fair Intelligence Test (CCFT), Delay Matching to Sample (DMS), Rapid Visual Information Processing (RVP)], and functioning [Functioning Assessment Short Test (FAST)] were collected. P3a and MMN were elicited using a passive auditory oddball paradigm.ResultsSignificant MMN and P3a deficits and impaired neurocognition were found in both SZ and BPD patients. In SZ, MMN was significantly correlated with FAST (r = 0.48) and CCFT (r = −0.31). In BPD, MMN was significantly correlated with DMS (r = −0.54). For P3a, RVP and FAST scores were significant predictors in SZ, whereas RVP, WAIS and FAST were significant predictors in BPD.ConclusionsThe present study found deficits in MMN, P3a, neurocognition in drug naïve SZ and BPD patients. These deficits appeared to link with levels of higher-order cognition and functioning.

Published: September 2021

AbstractObjective:To understand the key mechanisms that support healthy dietary habits promoted by fruit and vegetable (F&V) box schemes, testing relevant behaviour change triggers identified under the COM-B model in an evaluation research study of a Portuguese F&V box scheme (PROVE).Design:Correlation study with a post-test-only non-equivalent group design based on survey data. The mechanisms underpinning the differences between subscribers and non-subscribers are operationalised as mediation effects. Data availability, theoretical relevance and empirical validation supported the selection and testing of four potential mediators for the effects of subscribing to the box scheme on F&V consumption. These estimations derive from the coefficients of a structural equation model combined with the product coefficient approach and Sobel test.Setting:The study is part of a wider evaluation study on the impact of the PROVE box scheme on sustainability, health and equity.Participants:A sample of PROVE box subscribers (n 294) was compared with a matched subsample of non-subscribers (n 571) in a nationally representative survey.Results:Subscribing to the PROVE box correlates with an increased probability of eating at least five portions of F&V, irrespective of differences in age, education and perceived economic difficulties. Diet quality perceptions, and more robustly, the strength of meal habits and household availability were identified as relevant mediators.Conclusions:The subscription to an F&V box scheme is connected with proximal context that enables the consumption of F&V by ensuring more readily available F&V and better situational conditions associated with healthier meal habits.
Martian stick-like structures are not trace fossils: a new protocol for testing ichnogenicity synthesized from paleosol ichnology
Authors: Genise Jorge F. 
Published: September 2021

AbstractThere are different criteria that are usually analysed independently before identifying a new trace fossil, such as morphological regularity, completeness, dispersion, recurrence and complexity, surface morphology, and context. The synthesis of these criteria, as utilized in paleosol ichnology, composes a protocol that is presented herein for the first time and can be used for testing the ichnogenicity of trace-like structures in any paleoenvironment of Earth or Mars. As a study case, the Martian ‘stick-like structures’ do not fulfil any of the requirements posed by this protocol to be postulated as trace fossils. The ichnogenicity test, focussed exclusively on morphology and context, is simpler but equally useful as the biogenicity ones. It may be applied in the future with other potential cases before carrying on more complex analyses or to evaluate the astrobiological interest of trace-like structures.

Published: September 2021

Abstract

Aims
In the search for effective therapeutic strategies for depression, repetitive transcranial magnetic stimulation (rTMS) emerged as a non-invasive, promising treatment. This is because the antidepressant effect of rTMS might be related to neuronal plasticity mechanisms possibly reverting connectivity alterations often observed in depression. Therefore, in this review, we aimed at providing an overview of the findings reported by studies investigating functional and structural connectivity changes after rTMS in depression.

Methods
A bibliographic search was conducted on PubMed, including studies that used unilateral, excitatory (⩾10 Hz) rTMS treatment targeted on the left dorsolateral prefrontal cortex (DLPFC) in unipolar depressed patients.

Results
The majority of the results showed significant TMS-induced changes in functional connectivity (FC) between areas important for emotion regulation, including the DLPFC and the subgenual anterior cingulate cortex, and among regions that are part of the major resting-state networks, such as the Default Mode Network, the Salience Networks and the Central Executive Network. Finally, in diffusion tensor imaging studies, it has been reported that rTMS appeared to increase fractional anisotropy in the frontal lobe.

Limitations
The small sample size, the heterogeneity of the rTMS stimulation parameters, the concomitant use of psychotropic drugs might have limited the generalisability of the results.

Conclusions
Overall, rTMS treatment induces structural and FC changes in brain regions and networks implicated in the pathogenesis of unipolar depression. However, whether these changes underlie the antidepressant effect of rTMS still needs to be clarified.
Influence of herbicides on germination and quality of Palmer amaranth (Amaranthus palmeri) seed

Published: September 2021

AbstractLaboratory and greenhouse studies were conducted to evaluate the effects of chemical treatments applied to Palmer amaranth seeds or gynoecious plants that retain seeds to determine seed germination and quality. Treatments applied to physiologically mature Palmer amaranth seed included acifluorfen, dicamba, ethephon, flumioxazin, fomesafen, halosulfuron, linuron, metribuzin, oryzalin, pendimethalin, pyroxasulfone, S-metolachlor, saflufenacil, trifluralin, and 2,4-D plus crop oil concentrate applied at 1× and 2× the suggested use rates from the manufacturer. Germination was reduced by 20% when 2,4-D was used, 15% when dicamba was used, and 13% when halosulfuron and pyroxasulfone were used. Use of dicamba, ethephon, halosulfuron, oryzalin, trifluralin, and 2,4-D resulted in decreased seedling length by an average of at least 50%. Due to the observed effect of dicamba, ethephon, halosulfuron, oryzalin, trifluralin, and 2,4-D, these treatments were applied to gynoecious Palmer amaranth inflorescence at the 2× registered application rates to evaluate their effects on progeny seed. Dicamba use resulted in a 24% decrease in seed germination, whereas all other treatment results were similar to those of the control. Crush tests showed that seed viability was greater than 95%, thus dicamba did not have a strong effect on seed viability. No treatments applied to Palmer amaranth inflorescence affected average seedling length; therefore, chemical treatments did not affect the quality of seeds that germinated.
