Utilizing multi-level concepts for multi-phase modeling
Authors: Franz Tobias , Seidl Christoph , Fischer Philipp M. , Gerndt Andreas 
Published: January 2022

AbstractIn model-based systems engineering projects, engineers from multiple domains collaborate by establishing a common system model. Multi-level modeling is a technique that can be used to model the development from abstract ideas to concrete implementations. However, current multi-level modeling approaches are not adequate for processes with multiple modeling phases that might have to be rearranged later. In this paper, we introduce multi-phase modeling that utilizes concepts of multi-level modeling by considering a description of the expected phase ordering per domain. Constraints aware of this context can express that certain elements are only valid in specific phases without having to determine a concrete phase ordering for a particular model. This enables using multi-phase modeling in flexible workflows, adapting to changing requirements and the definition of access rules in domain notation. We show feasibility of this multi-phase modeling by applying it to multiple real-life systems engineering projects of the aerospace domain.
Manipulation-resistant false-name-proof facility location mechanisms for complex graphs
Authors: Nehama Ilan , Todo Taiki , Yokoo Makoto 
Published: January 2022

AbstractIn many real-life scenarios, a group of agents needs to agree on a common action, e.g., on a location for a public facility, while there is some consistency between their preferences, e.g., all preferences are derived from a common metric space. The facility location problem models such scenarios and it is a well-studied problem in social choice. We study mechanisms for facility location on unweighted undirected graphs that are resistant to manipulations (strategy-proof, abstention-proof, and false-name-proof) by both individuals and coalitions on one hand and anonymous and efficient (Pareto-optimal) on the other. We define a new family of graphs, $$ZV$$

ZV

-line graphs, and show a general facility location mechanism for these graphs that satisfies all these desired properties. This mechanism can also be computed in polynomial time and it can equivalently be defined as the first Pareto-optimal location according to some predefined order. Our main result, the $$ZV$$

ZV

-line graphs family and the mechanism we present for it, unifies all works in the literature of false-name-proof facility location on discrete graphs including the preliminary (unpublished) works we are aware of. In particular, we show mechanisms for all graphs of at most five vertices, discrete trees, bicliques, and clique tree graphs. Finally, we discuss some generalizations and limitations of our result for facility location problems on other structures: Weighted graphs, large discrete cycles, infinite graphs; and for facility location problems concerning infinite societies.

AbstractThe PROgress study assessed the value and feasibility of implementing web-based patient-reported outcomes assessments (PROs) within routine HIV care at two North American outpatient clinics. People with HIV (PWH) completed PROs on a tablet computer in clinic before their routine care visit. Data collection included PROs from 1632 unique PWH, 596 chart reviews, 200 patient questionnaires, and 16 provider/staff questionnaires. During an initial setup phase involving 200 patients, PRO results were not delivered to providers; for all subsequent patients, providers received PRO results before the consultation. Chart review demonstrated that delivery of PRO results to providers improved patient-provider communication and increased the number of complex health and behavioral issues identified, recorded, and acted on, including suicidal ideation (88% with vs 38% without PRO feedback) and anxiety (54% with vs 24% without PRO feedback). In post-visit questionnaires, PWH (82%) and providers (82%) indicated that the PRO added value to the visit.
Equivalent frame discretisation for URM façades with irregular opening layouts
Authors: Morandini Chiara , Malomo Daniele , Penna Andrea 
Published: January 2022

AbstractResearchers and practitioners widely employ simplified Equivalent Frame Models (EFM) for reproducing the in-plane governed response of unreinforced brick masonry (URM) structures, as they typically represent an acceptable compromise between numerical accuracy and computational cost. However, when considering URM structural systems with irregular opening distribution, the definition of the effective height and length of deformable components (i.e. pier and spandrel elements) still represents an open challenge. In this work, the influence of irregular distribution of openings on the predicted lateral response of full-scale URM façades was investigated. To this end, several geometrical combinations characterised by various degrees of irregularity were considered and idealised according to commonly employed EF discretisation approaches. Then, after a preliminary calibration process against experimental tests on both individual piers and a full-scale building façade, EFM results were compared with micro-modelling predictions, carried out within the framework of the Applied Element Method and used as a benchmark. Although in specific irregular configurations using some discretisation approaches, macro and micro-models converge to similar results, non-negligible differences in terms of initial lateral stiffness, base-shear and damage distribution were observed with other EF schemes or opening layouts, thus indicating that a careful selection of appropriate criteria is indeed needed when performing in-plane analyses of URM systems with irregular opening distributions. Finally, building on inferred simulated data, potential solutions are given to overcome typical EF discretisation issues and better approximate micro-modelling outcomes.

AbstractTuning the reaction parameters to maximize products yield is one of the major needs for any process. The goal of this research is to increase the reduction of CO2 with water by examining the operating parameters of a meso-scale continuous-flow type photochemical reactor over hydrothermally synthesized photocatalysts such as Pt/TiO2 and Pt/TiO2/RGO. Effects of catalyst type, weight of catalyst utilized, photochemical reactor temperature, retention time by variating the liquid water flow rate, and cocatalyst loading were investigated to increase the concentration of total organic carbon compounds including HCHO and CH3OH. The effect of titanium dioxide phase ratio (anatase: rutile) presence at the Pt/TiO2/RGO photocatalysts was also studied. The results revealed that the 0.3 wt.% Pt/TiO2/RGO5% photocatalyst which includes a phase ratio of 81:19 for anatase: rutile respectively has the superior photocatalytic activity to other studied photocatalysts. The physciochemical properties of different prepared photocatalytic samples were determined using various characterization techniques. Analyzing the liquid products on gas chromatography, it was found that CH3OH represents the major product whereas HCHO was the minor one. This reactor exhibits a great performance towards CO2 photocatalytic reduction under the optimized conditions.

Published: January 2022

AbstractAutomatic scheduling techniques are becoming a crucial tool for the efficient planning of large astronomical surveys. A specific scheduling method is being designed and developed for the Atmospheric Remote-sensing Infrared Exoplanet Large-survey (Ariel) mission planning based on a hybrid meta-heuristic algorithm with global optimization capability to ensure obtaining satisfying results fulfilling all mission constraints. We used this method to simulate theArielmission plan, to assess the feasibility of its scientific goals, and to study the outcome of different science scenarios. We conclude thatArielwill be able to fulfill the scientific objectives, i.e. characterizing$$\sim$$∼1000 exoplanet atmospheres, with a total exposure time representing about 75–80% of the mission lifetime. We demonstrate that it is possible to include phase curve observations for a sample of targets or to increase the number of studied exoplanets within the mission lifetime. Finally, around 12–15% of the time can still be used for non-time constrained observations.
Antecedents to the Adoption of Mobile Payment in China and Italy: an Integration of UTAUT2 and Innovation Resistance Theory

Published: January 2022

AbstractThis research aims to investigate the adoption gap in mobile payment systems between Italy and China, focusing on users’ intention to adopt mobile payment. The theoretical framing considers both drivers and barriers when combines the unified theory of acceptance and use of technology 2 (UTAUT2) with innovation resistance theory (IRT). To empirically verify the proposed model, this study gathers primary data through a web-based, self-administered survey. To analyze the data, we use structural equation modeling, and to test for significant differences between the two groups we run multi-group analysis. The respondents in Italy and China present different behaviors. Social influence plays a significant role in cultures with high uncertainty avoidance, such as Italy. The tradition barrier is the only significant barrier to the adoption of mobile payment.
Inhibition of harmful algal blooms caused by Aureococcus anophagefferens (Pelagophyceae) using native (Gracilaria tikvahiae) and invasive (Dasysiphonia japonica) red seaweeds from North America

Published: January 2022

AbstractHarmful algal blooms (HABs) caused by the pelagophyte Aureococcus anophagefferens have spread globally and are a threat to coastal ecosystems. Although some HAB mitigation techniques such as algal biocides can be effective, many such approaches can have negative consequences on the environment. Therefore, it is important to investigate alternative HAB mitigation approaches that are ecologically safe and commercially viable. Here, we examine the effects of two rhodophyte seaweeds, Gracilaria tikvahiae and Dasysiphonia japonica, on A. anophagefferens. During experiments, multiple A. anophagefferens strains were co-cultured with densities of seaweed encompassing a range of environmental and aquaculture settings (0.25–3.00 g L−1). The co-effects of nutrients, heterotrophic bacteria and pH were also assessed, and A. anophagefferens cell concentrations and photosynthetic efficiency were quantified. In nearly all experiments, G. tikvahiae and D. japonica significantly reduced A. anophagefferens cell concentrations in a dose-dependent manner, with the effectiveness of each seaweed depending primarily on both A. anophagefferens and seaweed densities. The algicidal effects of D. japonica were significantly stronger than G. tikvahiae and other algicidal seaweeds (e.g., Ulva spp.). Allelopathy was the most potent mechanism for inhibition of A. anophagefferens; heterotrophic bacteria, nutrient limitation and elevated pH appeared to have lesser co-effects. These findings, in conjunction with the well-known nutrient removal capacity of seaweeds, suggest that the temporal and spatial dynamics of these rhodophytes may influence brown tides in shallow estuaries and that the use of seaweeds such as G. tikvahiae in aquaculture may be a promising mitigation strategy for this and other HABs in coastal ecosystems.
Beyond the Problem of Bone Surface Preservation in Taphonomic Studies of Early and Middle Pleistocene Open-Air Sites
Authors: Pineda Antonio , Saladié Palmira 
Published: January 2022

AbstractA commonly identified problem in open-air sites is the poor preservation of bone surfaces because of the multiple agents and processes that act on them. In these assemblages, surface modifications of anthropic origin can be scarce or null, and its activity is mainly inferred through the stone tools and evidence of anthropogenic breakage. Carnivore activity is also frequent. La Mina and El Forn (Barranc de la Boella), Isernia La Pineta, and Torralba are open-air assemblages from the Early and Middle Pleistocene that have contributed to our knowledge of the activities that Lower Paleolithic hominins developed in open spaces. These sites show poorly preserved bone surfaces, evidence of carnivore activity, and few indications of human use on the faunal remains, although stone tools recovered are unequivocal sign of a hominin presence at those sites. Here, we present a synthesis of the taphonomic conducted at these sites with the aim of describing how this kind of work can be conducted at Paleolithic open-air sites using several different proxies, considering the limitations commonly identified in assemblages with poorly preserved bone surfaces. The absence or scarcity of cut marks could be related to the poor preservation of the faunal remains. However, it is impossible to affirm that any such marks were originally present, as hominins may have performed activities not linked to animal carcasses. Anatomical profiles have been presented as a useful tool for reconstructing the paleoecological environments and for allowing inferences to be made about the levels of competition among large predators. The assemblages reflect similarities in the deposition type of the remains and the use of these open spaces by hominins at different times during the Lower Paleolithic.
Broadening the design space of engineering materials through “additive grain boundary engineering”
Authors: Seita Matteo , Gao Shubo 
Published: January 2022

AbstractGrain boundary engineering (GBE) is one of the most successful processing strategies to improve the properties of polycrystalline solids. However, the extensive thermomechanical processes involved during GBE restrict its use to selected applications and materials. In this viewpoint paper, we discuss the opportunity provided by additive manufacturing (AM) technology to broaden the applicability of the GBE paradigm and, consequently, the design space for engineering materials. By integrating specially-designed thermomechanical processing within AM, it would be possible to produce bulk, near-net-shape parts with complex geometry and GBE microstructure. We discuss the major challenges in this endeavor and propose some possible strategies to achieve this goal, which we refer to as “additive-GBE”.
Well-Posedness for Stochastic Fractional Navier–Stokes Equation in the Critical Fourier–Besov Space

Published: January 2022

AbstractThe well-posedness of stochastic Navier–Stokes equations with various noises is a hot topic in the area of stochastic partial differential equations. Recently, the consideration of stochastic Navier–Stokes equations involving fractional Laplacian has received more and more attention. Due to the scaling-invariant property of the fractional stochastic equations concerned, it is natural and also very important to study the well-posedness of stochastic fractional Navier–Stokes equations in the associated critical Fourier–Besov spaces. In this paper, we are concerned with the three-dimensional stochastic fractional Navier–Stokes equation driven by multiplicative noise. We aim to establish the well-posedness of solutions of the concerned equation. To this end, by utilising the Fourier localisation technique, we first establish the local existence and uniqueness of the solutions in the critical Fourier–Besov space $$\dot{\mathcal {B}}^{4-2\alpha -\frac{3}{p}}_{p,r}$$

A state of the art review on the use of fungi in biofiltration to remove volatile hydrophobic pollutants
Authors: Marycz Milena , Brillowska-Dąbrowska Anna , Muñoz Raúl , Gębicki Jacek 
Published: January 2022

AbstractThe physical/chemical abatement of gas pollutants creates many technical problems, is costly and entails significant environmental impacts. Biological purification of off-gases is a cheap and ecologically safe way of neutralization of gas pollutants. Despite the recent advances, the main technological challenge nowadays is the purification of volatile organic compounds (VOCs) of hydrophobic character due to their low solubility in water. Among all known biological methods of air purification, the most cost-effective biodegradation of hydrophobic VOCs is conducted by biotrickling filters. In this context, fungi have gained an increasing interest in this field based on their ability to biodegrade hydrophobic VOCs. In addition, biotrickling filtration using fungi can support a superior hydrophobic VOC abatement when compared to the bacterial biofilters. This paper aims at reviewing the latest research results concerning biocatalytic activity of fungi and evaluating the possibilities of their practical application in biofiltration systems to remove hydrophobic VOCs.
A systematic review of magnetic versus conventional ureteric stents for short term ureteric stenting
Authors: Lyons Louise , Kinnear Ned , Hennessey Derek 
Published: January 2022

AbstractUreteric stents play an essential role in urology. However, patients can suffer a range of stent-related symptoms with stent in situ and during removal. Conventional ureteric stents are removed using a flexible cystoscopy, whereas magnetic stents may be rapidly removed with a smaller catheter-like retrieval device. The primary aim of this systematic review was to compare the morbidity including pain associated with conventional versus magnetic ureteric stents. The secondary aim was cost comparison. Searches were performed across databases, including Medline, Scopus, Embase and Cochrane. This review was performed in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). The search from the 5 databases returned a total of 358 articles. After duplicates were removed as well as the inclusion and exclusion criteria applied, a total of 6 studies were included in the final review. Ureteric Stent Symptoms Questionnaire (USSQ) and Visual Analogue Score (VAS) were used in most of the studies. All the studies reported that magnetic ureteric stents resulted in a reduction in the pain on the removal of magnetic ureteric stents, and no statistically significant difference with indwelling ureteric stents. Furthermore, majority of the studies reported a reduction in the cost associated with magnetic ureteric stents. There is no significant difference in pain from indwelling ureteric stents. There is a reduction in pain with the removal of magnetic ureteric stents compared to conventional removal via cystoscopy and an associated reduction in cost.
Pre-Reflective Self-Consciousness: A Meta-Causal Approach
Authors: Barnden John A. 
Published: January 2022

AbstractI present considerations surrounding pre-reflective self-consciousness (PRSC), arising in work I am conducting on a new physicalist, process-based account of [phenomenal] consciousness. The account is calledthe meta-causal account(MCA) because it identifies consciousness with a certain type of arrangement of meta-causation. Meta-causation is causation where a cause or effect is itself an instance of causation (e.g., A’s-causing-B causes C). The proposed type of arrangement involves a sort of time-spanning, internal reflexivity of the overall meta-causation. I argue that, as a result of the account, any conscious process has PRSC. Hence, PRSC does not need to be taken as a stipulation or argued for on purely phenomenological grounds or as a necessary support for reflective consciousness. I also show how it is natural to the account that PRSC is not an additional, peripheral, sort of consciousness, but is intrinsic to all consciousness, thereby fitting claims about self-intimation and co-constitution by various authors, and also being amenable to an adverbial account. As part of this, consciousness of an external object is just the form that current self-consciousness takes, the meta-causal constitution of it being inextricably modulated by the causal relationship with the object. The article also discusses how MCA helps explore issues of for-me-ness, transparency of perceptual consciousness, and possible immediacy and non-relationality of self-consciousness.
Stable Zn Metal Anodes with Limited Zn-Doping in MgF2 Interphase for Fast and Uniformly Ionic Flux

Published: January 2022

AbstractThe practical applications of aqueous Zn metal batteries are currently restricted by the inherent drawbacks of Zn such as the hydrogen evolution reaction, sluggish kinetics, and dendrite formation. To address these problems, herein, a limitedly Zn-doped MgF2 interphase comprising an upper region of pure, porous MgF2 and a lower region of gradient Zn-doped MgF2 is achieved via radio frequency sputtering technique. The porous MgF2 region is a polar insulator whose high corrosion resistance facilitates the de-solvation of the solvated Zn ions and suppression of hydrogen evolution, resulting in Zn metal electrodes with a low interfacial resistance. The Zn-doped MgF2 region facilitates fast transfer kinetics and homogeneous deposition of Zn ions owing to the interfacial polarization between the Zn dopant and MgF2 matrix, and the high concentration of the Zn dopant on the surface of the metal substrate as fine nuclei. Consequently, a symmetric cell incorporating the proposed Zn metal exhibits low overpotentials of ~ 27.2 and ~ 99.7 mV without Zn dendrites over 250 to 8000 cycles at current densities of 1.0 and 10.0 mA cm−2, respectively. The developed Zn/MnO2 full cell exhibits superior capacity retentions of 97.5% and 84.0% with average Coulombic efficiencies of 99.96% after 1000 and 3000 cycles, respectively.
