A real-time semantic visual SLAM for dynamic environment based on deep learning and dynamic probabilistic propagation
Authors: Chen Liang , Ling Zhi , Gao Yu , Sun Rongchuan , Jin Sheng 
Published: March 2023

AbstractMost existing visual simultaneous localization and mapping (SLAM) algorithms rely heavily on the static world assumption. Combined with deep learning, semantic SLAM has become a popular solution for dynamic scenes. However, most semantic SLAM methods show poor real-time performance when dealing with dynamic scenes. To handle this problem, a real-time semantic SLAM method is proposed in this paper, combining knowledge distillation and dynamic probability propagation strategy. First, to improve the execution speed, a multi-level knowledge distillation method is adopted to obtain a lightweight segmentation model, which is more suitable for continuous frames to create an independent semantic segmentation thread. This segmentation thread only accepts keyframes as input so that the system can avoid time delay caused by processing each frame. Second, a static semantic keyframe selection strategy is proposed based on the segmentation results. In this way, those keyframes containing more static information will be selected to reduce the participation of dynamic objects. By combining segmentation results and data matching algorithm, our system can realize the update and propagation of dynamic probability, reducing the influence of dynamic points in the pose optimization process. Validation results based on the KITTI and TUM datasets show that our method can effectively deal with dynamic feature points and improve running speed simultaneously.
The Quality of Regional Institutional Context and Museum Service Provision: Evidence from Italy
Authors: Cellini Roberto , Cuccia Tiziana , Ferrante Livio , Lisi Domenico 
Published: March 2023

AbstractThis study evaluates whether and how the services provided by Italian museums are influenced by the quality of the institutional context at the regional level. Institutional quality is measured by a range of indicators largely employed in the literature, such as the Institutional Quality Index (IQI), the European Quality of Government Index (EQI), and their components. Resorting to spatial autoregressive models, the presence of spatial dependence in museum service provision is also investigated. The analysis shows that the common institutional context is significant, especially for public museums, and it explains part of the spatial correlation among museums within regions.
Public Awareness of Medical Research Terminology in Japan, and the Accuracy of Physicians’ Predictions regarding that Awareness
Authors: Kamisato Ayako , Hong Hyunsoo , Okubo Suguru 
Published: March 2023

Abstract
One of the ethical principles of medical research involving human subjects is obtaining proper informed consent (IC). However, if the participants’ actual awareness of medical research terminology is lower than the researchers’ prediction of that awareness, it may cause difficulty obtaining proper IC. Therefore, this study aims to clarify the presence of “perception gaps” and then discuss IC-related issues and measures based on the insights obtained. We conducted two online surveys: a “public survey” to understand the Japanese public’s awareness of 11 medical research terms and a “physicians’ survey” to investigate physicians’ predictions regarding public awareness. In the “public survey,” for each term, respondents were instructed to select their situation from “understand,” “have heard,” or “have never heard.” In the “physicians’ survey,” respondents were asked to estimate the proportions of the general public who would “have understood,” “have heard,” or “have never heard” by using an 11-step scale. We analyzed separately in two age groups to understand the age-related difference. We received 1002 valid responses for the “public survey” and 275 for the “physicians’ survey.” Of the public respondents, more than 80% had never heard of terms such as interventional study, prospective clinical study, cohort study, Phase I clinical trial, or double-blind study. Concurrently, physicians overestimated general public awareness of the terms placebo, cohort study, double-blind study, and randomized clinical trial (in the group of people under 60). The results revealed the perception gap between the general public and physicians which raise serious concerns about obtaining proper IC from clinical research participants.
Advances in continuous polymer analysis in flow with application towards biopolymers
Authors: Patterson Samuel B. H. , Wong Raymond , Barker Graeme , Vilela Filipe 
Published: March 2023

AbstractBiopolymers, polymers derived from renewable biomass sources, have gained increasing attention in recent years due to their potential to replace traditional petroleum-based polymers in a range of applications. Among the many advantages of biopolymers can be included their biocompatibility, excellent mechanical properties, and availability from renewable feedstock. However, the development of biopolymers has been limited by a lack of understanding of their properties and processing behaviours. Continuous analysis techniques have the potential to hasten progress in this area by providing real-time insights into the properties and processing of biopolymers. Significant research in polymer chemistry has focused on petroleum-derived polymers and has thus provided a wealth of synthetic and analytical methodologies which may be applied to the biopolymer field. Of particular note is the application of flow technology in polymer science and its implications for accelerating progress towards more sustainable and environmentally friendly alternatives to traditional petroleum-based polymers. In this mini review we have outlined several of the most prominent use cases for biopolymers along with the current state-of-the art in continuous analysis of polymers in flow, including defining and differentiating atline, inline, online and offline analysis. We have found several examples for continuous flow analysis which have direct application to the biopolymer field, and we demonstrate an atline continuous polymer analysis method using size exclusion chromatography.

Optimal Stocker Production Strategies for Spring and Fall Calving Cow Herd
Authors: Key Cora , Boyer Christopher N. , Martinez Charles C. , Mason Katie M. 
Published: March 2023

AbstractWe determine optimal stocker strategies based on calving season, herd size, and the number of days of retention before marketing weaned calves. We estimate a hedonic pricing model for feeder cattle and incorporate this into a simulation model that considers the variability of cattle prices and feed costs. The profit and utility-maximizing decision for fall calving herd would be to retain weaned calves for 150-day postweaning. The producer marketing spring-born calves would prefer to sell these calves at weaning. The results are being utilized by extension to aid cattle producers in reducing their feed costs and increasing their profits.
Individual-level determinants of current trade union membership and previous trade union membership in European countries
Authors: Iner Mehmet 
Published: March 2023

AbstractThis article aimed to explore the individual-level determinants of current and previous trade union memberships and to question if certain patterns are prevalent among European countries. Accordingly, repeated logit models across 15 European countries are applied drawing on the ninth round of the European Social Survey data. Variables are selected primarily considering the supply–demand theory, which explains the union membership based on the idea that employees are seeking to maximise the utility through cost and benefit analysis. In this context, this article offers a comprehensive analysis of the determinants of trade union membership with findings suggesting that personal, occupational and workplace characteristics affect current membership while occupational and workplace characteristics have effects with inverse directions on current membership and previous membership.
Large-eddy simulation of tripping effects on the flow over a 6 : 1 prolate spheroid at angle of attack
Authors: Plasseraud Marc , Kumar Praveen , Mahesh Krishnan 
Published: March 2023

Large-eddy simulation is used to simulate the flow around a 6 : 1 prolate spheroid at

$10^\circ$

and

$20^\circ$

angles of attack, and Reynolds number

$4.2 \times 10^6$

. Flows with and without trip are compared to understand the relative effect of the trip on the state of the boundary layer and separation. For the tripped case, the geometry of the trip is resolved to better predict its effect on the downstream flow. The simulations employ overset grids that allow adequate resolution of the trips without significant increase in the overall computational cost. Results suggest that while the trip accelerates transition to turbulence at

$10^\circ$

, it does not induce a fully developed turbulent boundary layer as intended at

$20^\circ$

. Rather, the influence of the trip is localized, and the near-wall flow converges towards a solution similar to that of the non-tripped case upstream of separation. This is due to two distinct phenomena: directly downstream of the trip, favourable pressure gradient and streamline curvature effects suppress the disturbance on the windward side. Further along the spheroid, the boundary layer receives a small fraction of the initial perturbation due to spanwise and wall-normal streamline curvatures inducing a secondary flow that advects the low-momentum trip wake to the leeward side. The locations of transition and separation are insensitive to the presence of the trip. The simulation results are used to construct a regime map that identifies different regions characterized by distinct boundary layer properties and flow features. The present results underscore the difficulty associated with tripping smooth bodies at angle of attack, and the importance of accounting for transition in simulations of such flows, even on tripped geometries.
Chunking up speech in real time: linguistic predictors and cognitive constraints

Published: March 2023

AbstractThere have been some suggestions in linguistics and cognitive science that humans process continuous speech by routinely chunking it up into smaller units. The nature of the process is open to debate, which is complicated by the apparent existence of two entirely different chunking processes, both of which seem to be warranted by the limitations of working memory. To overcome them, humans seem to both combine items into larger units for future retrieval (usage-based chunking), and partition incoming streams into temporal groups (perceptual chunking). To determine linguistic properties and cognitive constraints of perceptual chunking, most previous research has employed short-constructed stimuli modeled on written language. In contrast, we presented linguistically naïve listeners with excerpts of natural speech from corpora and collected their intuitive perceptions of chunk boundaries. We then used mixed-effects logistic regression models to find out to what extent pauses, prosody, syntax, chunk duration, and surprisal predict chunk boundary perception. The results showed that all cues were important, suggesting cue degeneracy, but with substantial variation across listeners and speech excerpts. Chunk duration had a strong effect, supporting the cognitive constraint hypothesis. The direction of the surprisal effect supported the distinction between perceptual and usage-based chunking.

Published: March 2023

AbstractMexico is going through an environmental and nutritional crisis related to unsustainable dietary behaviours. Sustainable diets could solve both problems together. This study protocol aims to develop a three-stage, 15-week mHealth randomised controlled trial of a sustainable-psycho-nutritional intervention programme to promote Mexican population adherence to a sustainable diet and to evaluate its effects on health and environmental outcomes. In stage 1, the programme will be designed using the sustainable diets, behaviour change wheel and capability, opportunity, motivation, and behaviour (COM-B) models. A sustainable food guide, recipes, meal plans and a mobile application will be developed. In stage 2, the intervention will be implemented for 7 weeks, and a 7-week follow-up period in a young Mexican adults (18–35 years) sample, randomly divided (1:1 ratio) into a control group (n50) and an experimental group (n50), will be divided into two arms at week 8. Outcomes will include health, nutrition, environment, behaviour and nutritional-sustainable knowledge. Additionally, socio-economics and culture will be considered. Thirteen behavioural objectives will be included using successive approaches in online workshops twice a week. The population will be monitored using the mobile application consisting of behavioural change techniques. In stage 3, the effects of the intervention will be assessed using mixed-effects models on dietary intake and quality, nutritional status, physical activity, metabolic biomarkers (serum glucose and lipid profile), gut microbiota composition and dietary water and carbon footprints of the evaluated population. Improvements in health outcomes and a decrease in dietary water and carbon footprints are expected.
MAXENTIUS AS XERXES IN EUSEBIUS OF CAESAREA'S ACCOUNTS OF THE BATTLE OF THE MILVIAN BRIDGE
Authors: Serfass Adam 
Published: March 2023

AbstractOf the many accounts of the Battle of the Milvian Bridge ina.d.312 written soon after the conflict, only those of Eusebius of Caesarea have Maxentius cross the Tiber on a bridge of boats to face the forces of Constantine. This detail, it is here argued, suggests that Maxentius may be seen as a latter-day Xerxes, the Persian emperor who, in preparation for his invasion of Greece in 480b.c., famously spanned the Hellespont with a pair of boat-bridges. The article first reviews the seminal accounts of Xerxes’ feat in Aeschylus’Persiansand Herodotus’Histories, and next discusses the story's long afterlife in subsequent Greek (and Latin) authors, including those of Late Antiquity. Close analysis of Eusebius’ battle narratives in hisEcclesiastical History(9.9.3–8) and in hisLife of Constantine(1.38) reveals that their vocabulary echoes the distinctive language used by Aeschylus, Herodotus and later writers in reference to Xerxes’ achievement. The article concludes by exploring the implications of this identification of Maxentius with Xerxes. It exemplifies two venerable tactics in Roman political propaganda: that of portraying a native rival as a foreign enemy and that of mapping the Persian Wars onto contemporary events. As Xerxesrediuiuus, Maxentius is cast as the quintessential barbarian tyrant, an Eastern despot resident in Rome.
On the existence of baby skyrmions stabilized by vector mesons
Authors: Greco Carlo 
Published: March 2023

AbstractIn this paper, we prove the existence of topologically non-trivial solutions of the two-dimensional Adkins–Nappi model of nuclear physics; to this end, we minimize the energy functional by using the classical Skyrme ansatz, as well as a non-radially symmetric generalization of it. In both cases, we show that the minimization procedure preserves the topological degree of the minimization sequence.
Analytic theology and science-engaged theology
Authors: Leidenhag Joanna 
Published: March 2023

AbstractThis article contributes to ongoing discussions on the place of theology in secular research universities by examining the relationship between analytic theology and science-engaged theology. Writing in response to William Wood's Analytic Theology and the Academic Study of Religion, I consider if and how one might demarcate these two recent movements in academic theology given that both sociological and substantive definitions result in significant overlap. To show the extent of this overlap, I argue that both analytic theology and science-engaged theology are forms of faith seeking understanding, which use the tools and methods from other disciplines in order to make incremental progress on specific theological questions. I then offer two critiques of Wood's argument (made by analogy with the natural sciences) that the doctrine of creation provides theological warrant for the extension of common human reason seen in analytic philosophy and theology. My own attempt at a demarcation suggests that whereas analytic theology is best understood as an intellectual tradition, science-engaged theology is an intellectual disposition. This means that although science-engaged theology may not always be analytic, analytic theologians (and theologians more widely) should always be science-engaged.
Behavioural equivalences for continuous-time Markov processes
Authors: Chen Linan , Clerc Florence , Panangaden Prakash 
Published: March 2023

AbstractBisimulation is a concept that captures behavioural equivalence of states in a variety of types of transition systems. It has been widely studied in a discrete-time setting. The core of this work is to generalise the discrete-time picture to continuous time by providing a notion of behavioural equivalence for continuous-time Markov processes. In Chen et al. [(2019). Electronic Notes in Theoretical Computer Science347 45–63.], we proposed two equivalent definitions of bisimulation for continuous-time stochastic processes where the evolution is a flow through time: the first one as an equivalence relation and the second one as a cospan of morphisms. In Chen et al. [(2020). Electronic Notes in Theoretical Computer Science.], we developed the theory further: we introduced different concepts that correspond to different behavioural equivalences and compared them to bisimulation. In particular, we studied the relation between bisimulation and symmetry groups of the dynamics. We also provided a game interpretation for two of the behavioural equivalences. The present work unifies the cited conference presentations and gives detailed proofs.
New record of cold-adapted fauna on the Castilian Plateau: Woolly rhinoceros – Coelodonta antiquitatis (Blumenbach, 1799) – at La Mina (Burgos, Spain)
Authors: ARCEREDILLO Diego , DÍEZ FERNÁNDEZ-LOMANA Carlos , JORDÁ PARDO Jesús Francisco 
Published: March 2023

ABSTRACTLa Mina is one of three sites, along with Cueva Millán and La Ermita, located in the middle course of the Arlanza river. La Mina was excavated for the first time in 2006 and three test pits were carried out. In one of them, evidence of two Palaeolithic occupations was identified and several remains of woolly rhinoceros were recovered. Amino acid racemisation dating yielded an age of 52.5 ka BP, the earliest Upper Pleistocene date for Coelodonta antiquitatis on the Iberian Peninsula. This new record may have several implications for understanding the access routes to the Castilian Plateau, together with the definition of a new migratory wave of this species at the end of the Pleistocene. The location of La Mina on the Castilian Plateau may help researchers to complete the movements of this species through the Middle and Upper Palaeolithic on the Iberian Peninsula.

AbstractReviews of Geophysics is an AGU journal, first established in February 1963. It is a hybrid open access invitation‐only journal that publishes comprehensive review articles across various disciplines within the Earth and Space Sciences. The selection criteria are rigorous and many submissions are declined without review. The journal is the highest ranked in the fields of Geochemistry and Geophysics, with a high Journal Impact Factor (JIF2021 = 24.9), which is indicative of its high visibility and influence within the scientific community. The journal's published review papers, beyond a mere summary of literature, provide crucial context for current work, and establish the framework for comprehensive understanding of research progress, challenges, and interconnections between different communities, so that research may be appreciated by a broad audience. We emphasize the importance of publishing studies that provide a comprehensive overview and synthesis of the current state of knowledge in a field, especially in the case of geophysics, where knowledge is rapidly developing, increasing and becoming more specialized.
