We report charadriiform and charadriiform-like birds from the early Eocene London Clay of Walton-on-the-Naze (Essex, UK). A partial skeleton of a small modern-type charadriiform is described as a new species, Charadriisimilis essexensis n. gen. n. sp., and most closely resembles taxa of the Charadrii (plovers, stilts, oystercatchers, and other “wader-like” shorebirds). Affinities to this clade were also supported by phylogenetic analyses, which placed the fossil as the sister taxon of either the Burhinidae or all crown group Charadrii. In addition, we identify specimens of the charadriiform-like taxon Scandiavis, which was before known only from the early Eocene Fur Formation in Denmark. Associated limb elements of two individuals are classified as Scandiavis cf. mikkelseni Bertelli et al., 2013, and remains of two further individuals are tentatively assigned to Scandiavis. The presence of a processus supracondylaris dorsalis on the previously unknown humerus corroborates charadriiform affinities of Scandiavis, whereas a plesiomorphic hypotarsus morphology indicates a position outside crown group Charadriiformes. Charadriisimilis essexensis is one of the earliest modern-type charadriiforms, and the holotype of the species is the most substantial early Paleogene fossil record of a charadriiform bird. Together with Scandiavis, as the best-represented taxon to be considered as a stem group charadriiform, it provides the basis for an improved understanding of the evolutionary history of charadriiform birds.

The penultimate deglaciation was characterized by a sub-millennial-scale warm event in the Heinrich Stadial 11(HS11), termed the 134-ka event. However, its precise timing and structure remain poorly constrained due to the lack of high-resolution and precisely dated records. We present an oxygen isotope record of a speleothem with well-developed annual lamina from Zhangjia Cave, located on the north margin of the Sichuan Basin, characterizing Asian summer monsoon (ASM) changes in the 134-ka event, which included an increase excursion of ca. 149 years and decrease excursion of ca. 200 years, inferred from 3.3‰ δ18O variations. This event also divided the weak ASM interval-II (WMI-II), corresponding to HS11, into two stages, the WMI-IIa 132.8–134.1 ka and WMI-IIb 134.4–136.4 ka. With a comparable climatic pattern globally, the 134-ka event is essentially similar to the millennial-scale events in last glacial–deglacial period. Particularly, the observed weak-strong-weak ASM sequence (138.8–132.8 ka) is largely controlled by changes in the Atlantic Meridional Overturning Circulation (AMOC) forced by the meltwater of northern high-latitude ice sheets. Moreover, our results underpin that AMOC, rather than the global ice volume, is more critical to ASM variations during the last two deglaciations.

Crime groups are drawn to stealing heritage and cultural property because the thefts can be less dangerous than other illicit activities and there can be a lower chance of detection. In addition, there are financial opportunities such as selling the objects, using them as currency and collateral in illicit markets, and through rewards and ransoms. While these factors remain, crime groups operating as criminal entrepreneurs will continue to be attracted to this type of theft even if situational crime prevention strategies are implemented at locations. Unique and irreplaceable heritage and cultural property will be stolen, and societies will lose in artistic, cultural, heritage, historical, and financial terms. This article argues that, while people tasked with the policing and security of heritage and cultural property should focus on the potential thefts, policing agencies also need to focus on the crime groups, especially as heritage and cultural property thefts can be crime groups’ “Achilles’ heel.”

Interest in second language (L2) speech comprehensibility, or listeners’ perceived ease or difficulty of understanding a given utterance, has seen continual growth since Munro and Derwing's (1995) seminal publication in Language Learning. While recognizing the body of knowledge that has developed in the 25 plus years since Munro and Derwing's study, in the present paper we look to the future as we consider what an active and informative research agenda might look like for the next 10–15 years. In this regard, we propose four primary areas of future research, including a need to: (1) extend inquiry beyond a primary focus on L2 English speech, (2) explore comprehensibility more thoroughly as a social construct, (3) investigate the effects of more targeted task manipulations, and (4) delve deeper into the effects of comprehensibility-oriented instruction. We additionally discuss the need for more replication in L2 comprehensibility research while also promoting several scholarly disciplines we feel can greatly inform future research, such as task-based literature.

In order to complete many complex operations and attain more general-purpose utility, robotic grasp is a necessary skill to master. As the most common essential action of robots in factory and daily life environments, robotic autonomous grasping has a wide range of application prospects and has received much attention from researchers in the past decade. However, the accurate grasp of arbitrary objects in unstructured environments is still a research challenge that has not yet been completely overcome. A complete robotic grasp system usually involves three aspects: grasp detection, grasp planning, and control subsystem. As the first step, identifying the location of the object and generating the grasp pose is the premise of successful grasp, which is conducive to planning the subsequent grasp path and the realization of the entire grasp action. Therefore, this paper conducts a literature review focusing on grasp detection technology and concludes two significant aspects: the analytic and data-driven methods. According to the previous grasp experience of the target object, this paper divides the data-driven methods into the grasp of known and unknown objects. Then it describes in detail the typical grasp detection methods and related characteristics of each classification in the grasp of unknown objects. Finally, current research status and potential research directions in this field are discussed to provide some reference for related research.

Invasive alien species represent a multifaceted management problem in terms of threats to biodiversity and ecosystems and their impacts on agriculture and human well-being. Ambrosia artemisiifolia is an invasive alien plant in Europe that affects the human population as its already highly allergenic pollen can interact with air pollutants, resulting in detrimental effects on health. In this context, the invasive beetle Ophraella communa was proposed as a biocontrol agent of A. artemisiifolia, as it feeds on its leaves, leading to a decrease in pollen production. This paper takes advantage of the different co-occurrence classes obtained by the ecological niche models inferred for both of these species based on current and future climatic conditions. We integrate them with spatial data regarding major air pollutants (nitrogen dioxide and fine particulate matter). We couple this information with European human population density data at a narrow territorial scale to infer current and future statistically significant hotspots of health risk. The Netherlands and the UK host the widest hotspots within their national territory for both current (7.09% and 3.54%, respectively) and future (15.04% and 6.70%, respectively) scenarios. Considering the alarming results obtained for some areas, the monitoring and biocontrol of A. artemisiifolia should be applied as a European strategy.

Revolutionary protest rarely begins as democratic or revolutionary. Instead, it grows in a process of positive feedback, incorporating new constituencies and generating new demands. If protest is not revolutionary at its onset, theory should reflect this and be able to explain the endogenous emergence of democratic demands. In this article, I combine multiple data sources on the 2010–2011 Tunisian Revolution, including survey data, an original event catalogue, and field interviews. I show that the correlates of protest occurrence and participation change significantly during the uprising. Using the Tunisian case as a theory-building exercise, I argue that the formation of protest coalitions is essential, rather than incidental, to democratic revolution.

Hypercholesterolaemia is a major risk factor for CVD. Fish intake is associated with lower risk of CVD, whereas supplementation with n-3 long-chain PUFA (LC-PUFA) has little effect on the cholesterol concentration. We therefore investigated if cetoleic acid (CA), a long-chain MUFA (LC-MUFA) found especially in pelagic fish species, could lower the circulating total cholesterol (TC) concentration in rodents. A systematic literature search was performed using the databases PubMed, Web of Science and Embase, structured around the population (rodents), intervention (CA-rich fish oils or concentrates), comparator (diets not containing CA) and the primary outcome (circulating TC). Articles were assessed for risk of bias using the SYRCLE’s tool. A meta-analysis was conducted in Review Manager v. 5.4.1 (the Cochrane Collaboration) to determine the effectiveness of consuming diets containing CA-rich fish oils or concentrates on the circulating TC concentration. Twelve articles were included in the systematic review and meta-analysis, with data from 288 rodents. Consumption of CA-rich fish oils and concentrates resulted in a significantly lower circulating TC concentration relative to comparator groups (mean difference −0·65 mmol/l, 95 % CI (−0·93, −0·37), P < 0·00001), with high statistical heterogeneity (I2 = 87 %). The risk of bias is unclear since few of the entries in the SYRCLE’s tool were addressed. To conclude, intake of CA-rich fish oils and concentrates prevents high cholesterol concentration in rodents and should be further investigated as functional dietary ingredients or supplements to reduce the risk for developing CVD in humans.

In the wake of the Dobbs decision withdrawing federal constitutional protection for reproductive rights, the United States is in the throes of federalist conflicts. Some states are enacting draconian prohibitions of abortion or gender-affirming care, whereas other states are attempting to shield providers and their patients seeking care. This article explores standard arguments supporting federalism, including that it allows for cultural differences to remain along with a structure that provides for the advantages of common security and commerce, that it provides a laboratory for confined experiments, that it is government closer to the people and thus more informed about local needs and preferences, and that it creates layers of government that can constrain one another and thus doubly protect rights. We contend that these arguments do not justify significant differences among states with respect to the recognition of important aspects of well-being; significant injustices among subnational units cannot be justified by federalism. However, as nonideal theorists, we also observe that federalism presents the possibility of some states protecting rights that others do not. Assuming that movement among subnational units is protected, those who are fortunate enough to be able to travel will be able to access rights they cannot access at home. Nonetheless, movement may not be readily available to minors, people without documentation, people with disabilities, people who lack economic resources, or people who have responsibilities that preclude travel. Only rights protection at the federal level will suffice in such cases.

As biological organisms, we age and, eventually, die. However, age’s deteriorating effects may not be universal. Some theoretical entities, due to their synthetic composition, could exist independently from aging—artificial general intelligence (AGI). With adequate resource access, an AGI could theoretically be ageless and would be, in some sense, immortal. Yet, this need not be inevitable. Designers could imbue AGIs with artificial mortality via an internal shut-off point. The question, though, is, should they? Should researchers curtail an AGI’s potentially endless lifespan by deliberately making it mortal? It is this question that this article explores. First, it considers what type of AGI is under discussion before outlining how such beings could be ageless. Then, after clarifying the type of immortality under discussion and arguing that imbuing an AGI with synthetic aging would be person-affecting, the article explores four core conundrums: (i) deliberately causing a morally significant being’s death; (ii) immortality’s associated harms; (iii) concerns about immortality’s unequal assignment; and (iv) the danger of immortal AGI overlords. The article concludes that while prudence requires we create an aging AGI, in the face of the material harm such an action would constitute, this is an insufficient reason to justify doing so.

Despite the fact that older adults interact frequently with physicians, there is little research examining their preferences, and perceptions of the patient–physician relationship. Research on this topic is particularly sparse when it comes to older men. This study investigates older men’s experiences with physicians, their perceptions of the patient–physician relationship, and the extent to which they wished to be involved in their health care. In-depth, face-to-face interviews were conducted with 23 men 55–96 years of age. Findings reveal that older men want to participate in the medical encounter and be involved in their care, contradicting earlier work suggesting that older adults prefer to be passive patients. Preferred involvement, however, varied along a continuum ranging from “quasi-involvement” to “taking charge”, with most participants being in the middle, preferring a “partnership” patient–physician relationship. Factors influencing patient involvement and potential to negotiate the patient–physician relationship are discussed.

Diets deficient in fibre are reported globally. The associated health risks of insufficient dietary fibre are sufficiently grave to necessitate large-scale interventions to increase population intake levels. The Danish Whole Grain Partnership (DWP) is a public–private enterprise model that successfully augmented whole-grain intake in the Danish population. The potential transferability of the DWP model to Slovenia, Romania and Bosnia-Herzegovina has recently been explored. Here, we outline the feasibility of adopting the approach in the UK. Drawing on the collaborative experience of DWP partners, academics from the Healthy Soil, Healthy Food, Healthy People (H3) project and food industry representatives (Food and Drink Federation), this article examines the transferability of the DWP approach to increase whole grain and/or fibre intake in the UK. Specific consideration is given to the UK’s political, regulatory and socio-economic context. We note key political, regulatory, social and cultural challenges to transferring the success of DWP to the UK, highlighting the particular challenge of increasing fibre consumption among low socio-economic status groups – which were also most resistant to interventions in Denmark. Wholesale transfer of the DWP model to the UK is considered unlikely given the absence of the key ‘success factors’ present in Denmark. However, the DWP provides a template against which a UK-centric approach can be developed. In the absence of a clear regulatory context for whole grain in the UK, fibre should be prioritised and public–private partnerships supported to increase the availability and acceptability of fibre-rich foods.

The aim was to explore the implications of follicular output rate (FORT), ovarian sensitivity index (OSI), ovarian response prediction index (ORPI), and follicle-to-oocyte index (FOI) in low-prognosis patients defined by POSEIDON criteria. In total, 4030 fresh in vitro fertilization (IVF) cycles from January 2013 to October 2021 were included in this retrospective cohort analysis and were categorized into four groups based on the POSEIDON criteria. The FORT between Groups 1 and 2 (0.61 ± 0.34 vs. 0.65 ± 0.35, P = 0.081) and Groups 3 and 4 (1.08 ± 0.82 vs. 1.09 ± 0.94, P = 0.899) were similar. The OSI in the order from the highest to the lowest were 3.01 ± 1.46 in Group 1, 2.28 ± 1.09 in Group 2, 1.54 ± 1.04 in Group 3, and 1.34 ± 0.96 in Group 4 (P < 0.001). The trend in the ORPI values was consistent with that in the OSI. FORT, OSI, ORPI, and FOI complemented each other and offered excellent effectiveness in reflecting ovarian reserve and response, but they were not good predictors of clinical pregnancy rate (CPR) from IVF.
