Towards an effective application of parameter estimation and uncertainty analysis to mathematical groundwater models
Authors: Herrera Paulo A. , Marazuela Miguel Angel , Formentin Giovanni , Hofmann Thilo 
Published: July 2022

AbstractGroundwater models serve as support tools to among others: assess water resources, evaluate management strategies, design remediation systems and optimize monitoring networks. Thus, the assimilation of information from observations into models is crucial to improve forecasts and reduce uncertainty of their results. As more information is collected routinely due to the use of automatic sensors, data loggers and real time transmission systems; groundwater modelers are becoming increasingly aware of the importance of using sophisticated tools to perform model calibration in combination with sensitivity and uncertainty analysis. Despite their usefulness, available approaches to perform this kind of analyses still present some challenges such as non-unique solution for the parameter estimation problem, high computational burden and a need of a deep understanding of the theoretical basis for the correct interpretation and use of their results, in particular the ones related to uncertainty analysis. We present a brief derivation of the main equations that serve as basis for this kind of analysis. We demonstrate how to use them to estimate parameters, assess the sensitivity and quantify the uncertainty of the model results using an example inspired by a real world setting. We analyze some of the main pitfalls that can occur when performing such kind of analyses and comment on practical approaches to overcome them. We also demonstrate that including groundwater flow estimations, although helpful in constraining the solution of the inverse problem as shown previously, may be difficult to apply in practice and, in some cases, may not provide enough information to significantly constrain the set of potential solutions. Therefore, this article can serve as a practitioner-oriented introduction for the application of parameter estimation and uncertainty analysis to groundwater models.
Exploring the O2O (online to offline) marketing design of electric vehicles based on consumers’ emotions
Authors: Lin Chih-Kuan , Shen Kai-Shuan 
Published: July 2022

AbstractIn this study, we present how electric car marketing makes a practical appeal to elicit consumers’ emotions by its unique design characteristics to determine the essential attractive features that are beneficial for promoting the sales of this type of promising vehicle. Thus, we investigate why consumers prefer electric vehicles to fuel cars and what specific characteristics make them willing to own electric vehicles. Furthermore, the preference-based research method is applied to reveal the underlying meaning behind the appeal of electric cars in this study. Hence, this study uses the evaluation grid method to collect professional concepts and establish a semantic hierarchical diagram of preferences for electric vehicles. Then, quantification theory type I is used to analyze the questionnaire survey of consumers’ preferences. The three best original evaluation items of electric cars are determined, including “scenario-based,” “accessible,” and “visionary.” This study provides essential information for managers, designers, and researchers of electric vehicles. The study also contributes to the design, marketing, and consumer psychology.

Abstract
Due to the significant friction-reduction and anti-wear properties of nano particle, nano copper oxide (CuO) particle decorating on boron nitride nanosheets (BNNS) nanocomposites are fabricated with polydopamine (PDA) as the linking agent. The structural and morphological characteristics of the CuO@BNNS composite are characterized by scanning electron microscopy (SEM), X-ray diffraction patterns, fourier transform infrared spectroscopy and thermogravimetric analysis. The synergistic effect of CuO and BNNS on extreme pressure of lubrication oil are investigated. A four-ball tribometer is adopted to investigate the tribological behaviors of the as-prepared oil with different additives. Optical microscope and SEM are used to analyze the topography of worn surface. Energy dispersive spectroscopy is adopted to investigate the element distribution on worn surface. The results demonstrate that the CuO@BNNS nanoparticle could effectively improve the friction-reduction and anti-wear properties of the paraffin liquid, compared to paraffin liquid containing modified CuO (f-CuO) or PDA-BNNS respectively. The worn surface of steel ball presents smooth morphology for oil containing CuO@BNNS, contrast to oil containing f-CuO or PDA-BNNS respectively. With the tribo-film formation on the worn surface, the elements distribute uniformly on the worn surface for oil containing CuO@BNNS. Compared to lower load, the effect of load-carrying capacity and easy-shear property of CuO@BNNS outstand under 392 N, which results in the smooth worn surface compared to oil containing other additives.

Article Highlights
CuO@BNNS hybrid nanoparticle was prepared with a simple and mild method.
CuO@BNNS presents superior anti-friction and anti-wear properties due to the synergistic effect of nanoparticle.
The result obtained in the paper promotes the application of h-BN based nanocomposites in tribology.

Published: July 2022

AbstractThis study presents the microstructure and properties of vacuum electron beam welded WE43 magnesium alloy joint. The process parameters of acceleration voltage 150 kV, electron beam current 120 mA and welding speed 35 mm/s are used for vacuum electron beam welding of WE43 rare earth magnesium alloy plate. In this study, the main compositions of the weld are α-Mg and a small amount of eutectic rare earth phase β-Mg24Y5. The mass fraction of the rare earth phase β-Mg24Y5 in the weld area is more than that of the base metal. Segregation of Zr-rich particles can occur in weld zone. The average hardness of the weld is about 27% higher than that of the base metal, and the hardness near the center line of the weld is the highest. The yield strength, tensile strength and elongation of the joint are higher than that of the base metal by approximately 17%, 14% and 41%. Tensile fracture morphology of the welded joint is characterized by ductile and brittle mixed fracture. So, electron beam welding can achieve the connection of WE43 magnesium alloy plate with excellent microstructure and performance. It may be of great significance for this study to expand the application of rare earth magnesium alloy.

AbstractAgricultural management has a great influence on biodiversity and its services in agroecosystems. In Europe, a relevant proportion of biodiversity is dependent on low-input agriculture. To assess the effects of agricultural management on biodiversity, in this study we surveyed the communities of arable plants, diurnal flying insects, and pollinators in three conventional and in two organic fields of a traditional Elephant garlic (Allium ampeloprasum L.) crop of the Valdichiana area, in Tuscany (central Italy). The sampling was carried out twice during the season: in spring, during crop growing, and in summer, after crop harvesting. We assessed the effects of the different agricultural management on the richness and composition (species occurrence and abundance) of the three communities using univariate and multivariate analyses. Concerning our specific case study, only plant species richness was significantly higher in organic fields (15.7 ± 2.7 species per plot), compared to conventional ones (5.4 ± 2.3 species per plot). Regarding community composition, only pollinators showed a marginally significant difference between conventional and organic fields. Conversely, the effect of specific fields significantly explained differences in composition of all the investigated groups (plants, total insects, and pollinators). The results suggest that, in our case study, the emerged differences in diversity of the investigated communities were mainly attributable to environmental and management factors related to single fields, more than to organic or conventional farming. Such evidence could be partly due to the very local scale of the study, to the heterogeneity of the surveyed fields, and to the reduced number of surveyed fields. Further investigation is therefore needed.
Large-time behaviour and the second eigenvalue problem for finite-state mean-field interacting particle systems
Authors: Yasodharan Sarath , Sundaresan Rajesh 
Published: July 2022

AbstractThis article examines large-time behaviour of finite-state mean-field interacting particle systems. Our first main result is a sharp estimate (in the exponential scale) of the time required for convergence of the empirical measure process of the N-particle system to its invariant measure; we show that when time is of the order
$\exp\{N\Lambda\}$
for a suitable constant
$\Lambda > 0$
, the process has mixed well and it is close to its invariant measure. We then obtain large-N asymptotics of the second-largest eigenvalue of the generator associated with the empirical measure process when it is reversible with respect to its invariant measure. We show that its absolute value scales as
$\exp\{{-}N\Lambda\}$
. The main tools used in establishing our results are the large deviation properties of the empirical measure process from its large-N limit. As an application of the study of large-time behaviour, we also show convergence of the empirical measure of the system of particles to a global minimum of a certain ‘entropy’ function when particles are added over time in a controlled fashion. The controlled addition of particles is analogous to the cooling schedule associated with the search for a global minimum of a function using the simulated annealing algorithm.
Can vaccination intentions against COVID-19 be nudged?
Authors: Kantorowicz-Reznichenko Elena , Kantorowicz Jaroslaw , Wells Liam 
Published: July 2022

AbstractOnce vaccines against COVID-19 became available in many countries, a new challenge has emerged – how to increase the number of people who vaccinate? Different policies are being considered and implemented, including behaviourally informed interventions (i.e., nudges). In this study, we have experimentally examined two types of nudges on representative samples of two countries – descriptive social norms (Israel) and saliency of either the death experience from COVID-19 or its symptoms (UK). To increase the legitimacy of nudges, we have also examined the effectiveness of transparent nudges, where the goal of the nudge and the reasons of its implementation (expected effectiveness) were disclosed. We did not find evidence that informing people that the vast majority of their country-people intend to vaccinate enhanced vaccination intentions in Israel. We also did not find evidence that making the death experience from COVID-19, or its hard symptoms, salient enhanced vaccination intentions in the UK. Finally, transparent nudges as well did not change the results. We further provide evidence for the reasons why people choose not to vaccinate, and whether different factors such as gender, belief in conspiracy theories, political ideology, and risk perception, play a role in people's intentions to vaccinate or susceptibility to nudges.
A review of current knowledge about the importance of iodine among women of child-bearing age and healthcare professionals

Published: July 2022

Abstract
Iodine is required for thyroid hormone synthesis and fetal neurogenesis. Recent population studies in the United Kingdom (UK) have found iodine deficiency among schoolgirls, women of child-bearing age and pregnant women. This review explores knowledge and awareness of iodine among women of child-bearing age and healthcare professionals (HCPs) in the UK, set within a global context. We aimed to identify gaps in iodine knowledge in the current UK setting of iodine deficiency without iodine fortification and where iodine is not included in antenatal guidelines. The search terms ‘iodine knowledge’ and ‘iodine awareness’ were used to identify relevant papers. Iodine knowledge is poor among women of child-bearing age in the UK according to four studies using questionnaires and qualitative methods. They were unsure of dietary sources of iodine and were not consistently provided with relevant information from HCPs during clinical care. Midwives have been recognised as the main providers of dietary information during pregnancy and, although they recognised the importance of their role in providing nutrition advice, they did not feel equipped to do so and lacked confidence in addressing nutritional concerns. Globally, there was a similar lack of knowledge, however, this was somewhat improved by the inclusion of iodine in antenatal care guidelines. Midwives’ knowledge of iodine was poor, as was knowledge among women of child-bearing age. Improved HCP knowledge and effective communication of information to pregnant women and women planning to conceive may help to improve iodine status which is of particular concern in pregnancy.
Retinoic acid promotes tissue vitamin A status and modulates adipose tissue metabolism of neonatal rats exposed to maternal high-fat diet-induced obesity
Authors: Tan Libo , Zhang Yanqi , Wang Hui , Haberer Heleena 
Published: July 2022

Abstract
Maternal obesity may compromise the micronutrient status of the offspring. Vitamin A (VA) is an essential micronutrient during neonatal development. Its active metabolite, retinoic acid (RA), is a key regulator of VA homeostasis, which also regulates adipose tissue (AT) development in obese adults. However, its role on VA status and AT metabolism in neonates was unknown and it was determined in the present study. Pregnant Sprague-Dawley rats were randomised to a normal fat diet (NFD) or a high fat diet (HFD). From postnatal day 5 (P5) to P20, half of the HFD pups received oral RA every 3 d (HFDRA group). NFD pups and the remaining HFD pups (HFD group) received placebo. Six hours after dosing on P8, P14 and P20, n 4 pups per group were euthanised for different measures. It was found that total retinol concentration in neonatal liver and lung was significantly lower in the HFD group than the NFD group, while the concentrations were significantly increased in the HFDRA group. The HFD group exhibited significantly higher body weight (BW) gain, AT mass, serum leptin and adiponectin, and gene expression of these adipokines in white adipose tissue compared with the NFD group; these measures were significantly reduced in the HFDRA group. BAT UCP2 and UCP3 gene expression were significantly higher in pups receiving RA. In conclusion, repeated RA treatment during the suckling period improved the tissue VA status of neonates exposed to maternal obesity. RA also exerted a regulatory effect on neonatal obesity development by reducing BW gain and adiposity and modulating AT metabolism.
Le défi de l'institutionnalisation des savoirs d'expérience dans les services de rétablissement. Une approche pragmatiste
Authors: Aussedat Laure 
Published: July 2022

RésuméQue signifie concrètement reconnaître et valoriser les savoirs d'expérience dans le cadre de services de psychiatrie orientés vers le rétablissement ? À partir d'une étude des missions confiées aux « médiateurs de santé pairs », et en utilisant la théorie pragmatiste de John Dewey, il s'agit ici d'interroger les conditions de possibilité et les limites d'une institutionnalisation des savoirs des patients. Plutôt que de penser cette institutionnalisation en termes d'intégration d'informations, Dewey nous permet de la penser comme la mise en débat des cadres interprétatifs et des critères d’évaluation du rétablissement.
Solidarité, agentivité, autorité. Un siècle de tentatives d'autonomisation des patient.es en France (1918–2009)
Authors: Klein Alexandre 
Published: July 2022

RésuméLe processus d'autonomisation des patient.es qui s'opéra en France au cours du XXesiècle peut, artificiellement, être divisé en trois grandes périodes marquées par les principes de solidarité, d'agentivité et d'autorité. Cette tripartition permet de mieux saisir les enjeux de ce mouvement et de comprendre en quoi l'avènement de la démocratie sanitaire, auquel il a abouti au début du XXIesiècle, consiste, par sa dépolitisation des enjeux d'autonomie, au renvoi des patient.es vers une forme de subalternité qu'incarnent, paradoxalement, les nouvelles figures de patient expert ou partenaire.
Graded comodule categories with enough projectives
Authors: Salch Andrew 
Published: July 2022

AbstractIt is well known that the category of comodules over a flat Hopf algebroid is abelian but typically fails to have enough projectives, and more generally, the category of graded comodules over a graded flat Hopf algebroid is abelian but typically fails to have enough projectives. In this short paper, we prove that the category of connective graded comodules over a connective, graded, flat, finite-type Hopf algebroid has enough projectives. Applications to algebraic topology are given: the Hopf algebroids of stable co-operations in complex bordism, Brown–Peterson homology, and classical mod p homology all have the property that their categories of connective graded comodules have enough projectives. We also prove that categories of connective graded comodules over appropriate Hopf algebras fail to be equivalent to categories of graded connective modules over a ring.

Abstract
In daycare centres, the close contact of children with other children and employees favours the transmission of infections. The majority of children <6 years attend daycare programmes in Germany, but the role of daycare centres in the SARS-CoV-2 pandemic is unclear. We investigated the transmission risk in daycare centres and the spread of SARS-CoV-2 to associated households. 30 daycare groups with at least one recent laboratory-confirmed SARS-CoV-2 case were enrolled in the study (10/2020–06/2021). Close contact persons within daycare and households were examined over a 12-day period (repeated SARS-CoV-2 PCR tests, genetic sequencing of viruses, symptom diary). Households were interviewed to gain comprehensive information on each outbreak. We determined primary cases for all daycare groups. The number of secondary cases varied considerably between daycare groups. The pooled secondary attack rate (SAR) across all 30 daycare centres was 9.6%. The SAR tended to be higher when the Alpha variant was detected (15.9% vs. 5.1% with evidence of wild type). The household SAR was 53.3%. Exposed daycare children were less likely to get infected with SARS-CoV-2 than employees (7.7% vs. 15.5%). Containment measures in daycare programmes are critical to reduce SARS-CoV-2 transmission, especially to avoid spread to associated households.

Self-replicating probes are imminent – implications for SETI
Authors: Ellery Alex 
Published: July 2022

AbstractIn the early 1980s, the Sagan-Tipler debate raged regarding the interpretation of the Fermi paradox but no clear winner emerged. Sagan favoured the existence of ETI on the basis of the Copernican principle and Tipler favoured the non-existence of ETI on the basis of the Occam's razor principle. Tipler's stance was an expansion of the similar but earlier Hart declaration. However, crucial to the Tipler argument was the role played by self-replicating interstellar robot probes. Any technologically capable species will develop self-replication technology as the most economical means of exploring space and the Galaxy as a whole with minimal investment. There is no evidence of such probes in our solar system including the asteroid belt, ergo, ETI do not exist. This is a powerful and cogent argument. Counter-arguments have been weak including Sagan's sociological explanations. We present a Copernican argument that ETI do not exist – humans are developing self-replication technology today. We are developing the ability to 3D print entire robotic machines from extraterrestrial resources including electric motors and electronics as part of a general in-situ resource utilization (ISRU) capability. We have 3D-printed electric motors which can be potentially leveraged from extraterrestrial material that should be available in every star system. From a similar range of materials, we have identified a means to 3D print neural network circuitry. From our industrial ecology, self-replicating machines and indeed universal constructors are feasible. We describe in some detail how a self-replicating interstellar spacecraft may be constricted from asteroidal resources. We describe technological signatures of the processing of asteroidal material (which is expected to be common to most star systems), and the excess production of certain types of clay and other detritus materials. Self-replication technology is under development and imminent – if humans are pursuing self-replication technology, then by the Copernican principle, so would any technologically savvy species elsewhere. There is no evidence that they have.
