Is order creation through disorder in additive manufacturing possible?

Abstract Additive manufacturing is based on a deterministic principle of spatially localized material transformation. By using spatial energy resolution modes, it is thus possible to produce an object that meets a set of specifications in a step-by-step manner. This paper attempts to take the opposite view by examining whether it is interesting to use knowledge on “morphogenesis” (cf. Alan Turing) and other conceptual ideas of spontaneous self-organization to achieve a desired shape. This new and more systemic form of 3D/4D printing enables the self-assembly and establishment of elements (voxels) in various environments through the use of programmable or smart matter. The necessary convergence of interacting elements requires a related decisive activity, however, to the sign of unknown, indecision, complexity, unpredictable bifurcations, in short of scientific promise that cannot be robustly kept. Beyond this frame of generalized non-decidability—a form of abandonment of self-organization paradigm in favour of deterministic doctrines—, there are paths to partial success where desired spatial transformations can be created through (mastered? ) disorder. The paper presents the conceptual bases of 3D self-organization with some illustrative examples. The objective is to highlight the interests of this disruptive vision with its realistic limits.
Inclusive museum audio guides: ‘guided looking’ through audio description enhances memorability of artworks for sighted audiences

ABSTRACT Museums aim to offer engaging and memorable visitor experiences, but their visuo-centric bias can prove challenging for people both with and without sight. Audio Description was developed to convey visual information through verbal description to blind and partially sighted audiences. However, cognitive psychology suggests it could enhance memorability for sighted visitors by stimulating ‘guided looking’. In this study, three groups of participants viewed nine photographs from the Museum of London’s collections, with either no audio, a standard audio guide or an audio descriptive guide. Enjoyment and emotional responses were similar for all groups. However, one month later, audio participants recalled more photos and were more likely to have re-engaged with the collection. Crucially, audio descriptive guide participants recalled most details about the photos. This suggests that inclusive audio descriptive guides could enhance access and memorability for sighted visitors, as well as expanding crucial access provisions for blind and partially sighted people.
Plant-Microbe Synergism in Floating Treatment Wetlands for the Enhanced Removal of Sodium Dodecyl Sulphate from Water

Excessive use of detergents in wide industrial processes results in unwanted surfactant pollution. Among them, sodium dodecyl sulphate (SDS) has well-known history to be used in pharmaceutical and industrial applications. However, if discharged without treatment, it can cause toxic effects on living organisms especially to the aquatic life. Floating treatment wetlands (FTWs) could be a cost-effective and eco-friendly options for the treatment of wastewater containing SDS. In this study, FTWs mesocosms were established in the presence of hydrocarbons-degrading bacteria. Two plant species (Brachiaria mutica and Leptochloa fusca) were vegetated and a consortium of bacteria (Acinetobacter sp. strain BRSI56, Acinetobacter junii strain TYRH47, and Acinetobacter sp. strain CYRH21) was applied to enhance degradation in a short-time. Results illustrated that FTWs vegetated with both plants successfully removed SDS from water, however, bacterial augmentation further enhanced the removal efficiency. Maximum reduction in SDS concentration (97.5%), chemical oxygen demand (92.0%), biological oxygen demand (94.2%), and turbidity (99.4%) was observed in the water having FTWs vegetated with B. mutica and inoculated with the bacteria. The inoculated bacteria showed more survival in the roots and shoots of B. mutica as compared to L. fusca. This study concludes that FTWs have the potential for the removal of SDS from contaminated water and their remediation efficiency can be enhanced by bacterial augmentation.
Mathematical Modelling of MHD Natural Convection in a Linearly Heated Porous Cavity

Received: 26 November 2020 Accepted: 3 February 2021 A linear increase in thermal boundaries towards the bottom of the porous cavity is considered for numerical flow analysis on MHD natural convection. The twodimensional square shaped cavity is filled with the Cu-water nanofluid. The dimensionless equations are considered to interpret the fluid and heat flow inside the cavity with respect to the desired boundaries. The governing equations are solved using the finite difference techniques. The relevant dimensionless parameters used in the present study are Rayleigh number, Darcy number, solid volume fraction of the nanoparticles and Hartmann number to obtain the flow fields. Heatline flows picturization techniques involved in the study analyze the heat flow inside the cavity. As the Rayleigh number and Darcy number increases, an increase in streamlines flow velocity and convection heat transfer is observed. Convective heat transfer is interrupted by increasing the applied magnetic field effects. An improvement in the heat transfer is noticed by increasing the solid volume fraction of the particles.
UV-Indien Network ground-based measurements: comparisons
with satellite and model estimates of UV radiation over the Western
Indian Ocean

Abstract. As part of the UV-Indien Network, 9 ground-based stations have been equipped with one spectroradiometer, radiometers and all-sky cameras. These stations are homogeneously distributed in 5 countries of the Western Indian Ocean region (Comoros, France, Madagascar, Mauritius and Seychelles), a part of the world where almost no measurements have been made so far. The main scientiﬁc objectives of this network are to study the annual and inter-annual variability of the ultraviolet (UV) radiation in this area, to validate the output of numerical models and satellite estimates of ground-based UV measurements, and to monitor UV radiation in the context of climate change and projected ozone depletion in this region. The ﬁrst results are presented here for the oldest stations (Antananarivo, Anse Quitor, Mahe and Saint-Denis). Ground-based measurements of UV index (UVI) are compared against satellite estimates (Ozone Monitoring Instrument (OMI), the TROPOspheric Monitoring Instrument (TROPOMI), the Global Ozone Monitoring Experiment (GOME) and model forecasts of UVI (Tropospheric Emission Monitoring Internet Service (TEMIS) and Copernicus Atmospheric Monitoring Service (CAMS). The median relative differences between satellite or model estimates and ground-based measurements of clear-sky UVI range between −34.5 % and 15.8 %. Under clear skies, the smallest UVI median difference between the satellites or model estimates and the measurements of ground-based instruments is found to be 0.02 (TROPOMI), 0.04 (OMI), −0.1 (CAMS) and −0.4 (CAMS) at St-Denis, Antananarivo, Anse Quitor and Mahe respectively. The cloud fraction and UVI diurnal proﬁle are calculated for these four stations. The mean UVI values at local solar noon range between 10 (Antananarivo, Anse Quitor and Saint-Denis) and 14 at Mahe. The mean UVIs in clear-sky conditions are higher than mean UVI in all-sky conditions, although it can still be noted that UVI maxima are higher for all-sky conditions than for clear sky conditions. This is the result of UVI enhancement induced by clouds, observed at these four stations. The greatest increase in UV radiation under cloudy conditions was observed at the Mahe station, with increases of more than 4. The data used in this study is available at https://doi.org/10.5281/zenodo.4572026 (Lamy and Portafaix, 2021).
A study of fake news reading and annotating in social media context

ABSTRACT The online spreading of fake news is a major issue threatening entire societies. Much of this spreading is enabled by new media formats, namely social networks and online media sites. Researchers and practitioners have been trying to answer this by characterising the fake news and devising automated methods for detecting them. The detection methods had so far only limited success, mostly due to the complexity of the news content and context and lack of properly annotated datasets. One possible way to boost the efficiency of automated misinformation detection methods is to imitate the detection work of humans. It is also important to understand the news consumption behaviour of online users. In this paper, we present an eye-tracking study, in which we let 44 lay participants to casually read through a social media feed containing posts with news articles, some of which were fake. In a second run, we asked the participants to decide on the truthfulness of these articles. We also describe a follow-up qualitative study with a similar scenario but this time with seven expert fake news annotators. We present the description of both studies, characteristics of the resulting dataset (which we hereby publish) and several findings.
An Optimization Route Selection Method of Urban Oversize Cargo Transportation

In order to select the optimal transportation route among alternative transportation routes more accurately and objectively, the choice of urban oversize cargo transportation routes was studied by taking the optimization weight–TOPSIS combination method for specific calculations. This model, based on an entropy weight method, cloud model, and TOPSIS method, combines the superiority of the cloud model for reflecting the randomness and discreteness of subjective evaluation with the advantages of the TOPSIS method in dealing with the problem of multi-objective programming. Through selecting and classifying several the main road influencing factors of urban oversize cargo transportation, based on the data of four urban roads, the entropy weight method is used to initially determine the weights of each influencing factor, the cloud model is used to optimize weights, the TOPSIS method is used to compare and evaluate the paths, and the optimal transportation route is selected on this basis. The results showed that the optimization weight–TOPSIS method is scientific and accurate for the multi-objective planning of oversize cargo transportation route selection, and solves the problem of the impact of subjective factors in existing methods and the difficulty of processing multiple influencing factors. The Pearson consistency test results show that the Pearson correlation coefficient between the proposed method and the actual oversize cargo transportation route selection is 0.995, which is higher than the calculation results without using the combination weight.
Detection of voids behind segments in the shield tunnels by using Ground Penetrating Radar

Metro traffic in subsurface tunnels is under a rapid development in many cities in the recent decades. However, the voids and other concealed defects inside and/or behind the tunnel lining pose critical threat to the safety of the operating metro tunnels. Ground penetrating radar (GPR) is a non-destructive geophysical technique by transmitting electromagnetic (EM) waves and receiving the reflected signals. GPR has proved its capability in the detection of the existence of tunnel structural defects and anomalies. However, the voids are still hard to be recognized in a GPR image due to the strong scattering clutter caused by the dense steel bars reinforced inside the concrete lining [1]. In this paper, we analyze the propagations of EM waves through reinforce concrete segments of shield tunnels by finite difference time domain (FDTD) simulations and model test. Firstly, a series of simulations results we have done, indicates that the center frequency of GPR ranges from 400 MHz to 600 MHz has a good penetration through the densely reinforced concrete lining. And the distance between the antennas and the surface of shield tunnel segments should be less than 0.2 m to ensure a good coupling of incident electromagnetic energy into the concrete structure. Then, to image the geometric features of the void behind the segment, reverse-time migration method is applied to the simulated GPR B-scan profile, which presents higher resolution results than the results by using the traditional diffraction stack migration (Figure 1) [2]. Finally, the field experiment results prove that a commercial GPR system operating at a center frequency of 600 MHz do detect a void behind the shield tunnel (Figure 2). The reflection from the void, which starts from the back interface of the segments and lasts over 20 ns, are significantly different from the reflections from the rebars (Figure 3). In summary, GPR has potential in the detection of voids behind the shield tunnel segment. More simulations and field experiments will be performed in the future.

Combined Serum Golgi Membrane Glycoprotein 73 Improves the Accuracy of Transient Elastography for Significant Fibrosis Detection in Patients with Chronic HBV Infections

Background: Golgi membrane glycoprotein 73 (GP73) serum level is a potential biomarker for diagnosing significant fibrosis and cirrhosis in chronic liver diseases. Objectives: The current study aimed to evaluate the accuracy of GP73 serum levels as a biomarker in the diagnosis of significant liver fibrosis in patients with hepatitis B virus (HBV). A new promising algorithm was developed by combining LSM and GP73 to predict significant liver fibrosis. Methods: Information on the following parameters were obtained from 165 patients with HBV: liver stiffness measurement (LSM), serum GP73 level, and some other fibrosis criteria approved for clinical practice. The area under the curve (AUC) and sensitivity and specificity of GP73 were compared with LSM, aminotransferase-to-platelet ratio index (APRI), and 4-factor based fibrosis index (FIB-4) for diagnosing significant fibrosis. Results: Compared to the non-significant liver fibrosis patients, the HBV infected patients with significant fibrosis showed a higher level of serum GP73 [64.05 (24.41 - 144.39) versus 91.30 (31.81 - 200.05) ng/mL, P < 0.001]. Concerning significant fibrosis diagnosis, GP73 exhibited advantages regarding the AUC (0.702), sensitivity (69.3%), and specificity (66.0%). Besides, GP73 did not show any advantage over LSM and APRI, but it had a better performance than FIB-4 in significant fibrosis detection. For the newly developed algorithm combining GP73 with LSM, the AUC, sensitivity, and specificity were 0.848, 77.4%, and 83.5%, respectively; hence, it's superior to LSM (0.832, 72.6%, and 83.5%, respectively; P = 0.016) for diagnosing significant fibrosis. Conclusions: This study demonstrated that GP73 can be considered as a new effective biomarker for diagnosing liver fibrosis. The accuracy of significant fibrosis detection in patients with HBV infection can be improved by the new algorithm that contains GP73 and LSM.
Electronic control of molecular configuration instability via vibronic coupling. Comparison of CuCl3-5 with ZnCl3-5

In order to reveal the main features of electronic control of nuclear configuration instability via vibronic coupling two similar systems, CuCl 5 3- (I) and ZnCl 5 3- (II), which differ by one d electron in the electronic shell of the central atom, 3d 9 versus 3d 10 , are studied and compared in detail. The reference configuration of these two systems is taken trigonal bipyramidal (TBP) and its possible instability with respect to one normal E' and one normal A 2 distortion is examined. The electronic structure, the constants of pseudo Jahn-Teller coupling to the corresponding excited states, and the vibronic contribution to the instability of the ground state are calculated in the semiempirical MO LCAO valence basis SCCC approximation
FROM BUSINESS DISASTER TO PROFESSIONAL BREAKTHROUGH: THE COPING MECHANISMS OF FILIPINO MIGRANT WORKERS, A PHENOMENOLOGY

Background: Some businesses, compared to million-dollar enterprises, fail to make an impact. As a result, some entrepreneurs resort to closing their businesses. To excel in their professions, they need to cope with business losses. Method: This paper used a phenomenological design to understand the participants lived experiences, particularly Filipino migrant workers who have experienced business loss, relative to the central question, How do Filipino professionals cope with business loss? Findings: Filipinos displaying entrepreneurial characteristics (business mindedness, profit orientation, future planning) have desires to raise enterprises. However, entrepreneurial trials (e.g. management issues, competition issues, financial burdens) will be faced, which result in business losses. They coped with losses through entrepreneurial solutions, specifically career motivation and family motivation. Conclusion: Maintaining an enterpriseis never easy as it requires sacrifices, time, and especially money. Business disasters come with overwhelming consequences and complications. Nevertheless, after facing different challenges of experiencing business loss, former entrepreneurs can achieve breakthroughs. This research aims to help future entrepreneurs cope with predicted business losses. Recommendation: The researchers recommend considering other coping mechanisms to explore other options for future entrepreneurs. Furthermore, it is also recommended to focus on one business nature and one employment sector to achieve more specific findings.
Physical Exercise Improves Heart-Rate Variability in Obese Children and Adolescents: A Systematic Review

Background: Childhood obesity has negative impact on heart-rate variability (HRV) and, thereby, on the cardiovascular health of children and adolescents. Thus, physical-exercise interventions were proposed to increase HRV. The present systematic review aims to provide an up-to-date analysis of research on the effect of physical-exercise interventions on HRV in obese children and adolescents. Methods: An electronic search of the literature was performed, and 10 articles were included. PRISMA guideline methodology was employed. Results: Physical-exercise interventions predominantly involved aerobic training; however, alternative training programs, including judo or recreational soccer, were found. The duration of intervention ranged from 6 to 24 weeks, with a training frequency of between 2 and 7 times per week. The duration of sessions typically ranged from 40 to 60 min. Conclusions: Results of the included articles indicated that physical-exercise intervention increased the HRV and thereby the autonomic modulation of obese children and adolescents. This is significant, as HRV is associated with cardiovascular health. Such physical-exercise interventions are crucial to reduce weight and improve cardiovascular health in children and adolescents, thereby achieving a sustainable future.
Implications for Extraterrestrial Hydrocarbon Chemistry: Analysis of Ethylene (C2H4) and D4-Ethylene (C2D4) Ices Exposed to Ionizing Radiation via Combined Infrared Spectroscopy and Reflectron Time-of-flight Mass Spectrometry

The processing of the hydrocarbon ice, ethylene (C2H4/C2D4), via energetic electrons, thus simulating the processes in the track of galactic cosmic-ray particles, was carried out in an ultrahigh vacuum apparatus. The chemical evolution of the ices was monitored online and in situ utilizing Fourier transform infrared spectroscopy (FTIR) and during temperature programmed desorption, via a quadrupole mass spectrometer utilizing electron impact ionization (EI-QMS) and a reflectron time-of-flight mass spectrometer utilizing a photoionization source (PI-ReTOF-MS). Several previous in situ studies of ethylene ice irradiation using FTIR were substantiated with the detection of six products: [CH4 (CD4)], acetylene [C2H2 (C2D2)], the ethyl radical [C2H5 (C2D5)], ethane [C2H6 (C2D6)], 1-butene [C4H8 (C4D8)], and n-butane [C4H10 (C4D10)]. Contrary to previous gas phase studies, the PI-ReTOF-MS detected several groups of hydrocarbon with varying degrees of saturation: CnH2n+2 (n = 4–10), CnH2n (n = 2–12, 14, 16), CnH2n−2 (n = 3–12, 14, 16), CnH2n−4 (n = 4–12, 14, 16), CnH2n−6 (n = 4–10, 12), CnH2n−8 (n = 6–10), and CnH2n−10 (n = 6–10). Multiple laboratory studies have shown the facile production of ethylene from methane, which is a known ice constituent in the interstellar medium. Various astrophysically interesting molecules can be associated with the groups detected here, such as allene/methylacetylene (C3H4) or 1, 3-butadiene (C4H6) and its isomers, which have been shown to lead to polycyclic aromatic hydrocarbons. Finally, several hydrocarbon groups detected here are unique to ethylene ice versus ethane ice and may provide understanding of how complex hydrocarbons form in astrophysical environments.
The problematization of ‘star architecture’ in architecture research

ABSTRACT Despite of the growth of the body of scholarly literature on the topic star architecture, few articles cite publications of architectural research on the topic. The scholarly discussion of star architecture is only marginally influenced by the problematizations specific to the architecture field. This paper presents findings of a systematic quantitative literature review of the topic star architecture. By searching Scopus and Avery databases using relevant keywords, a total of 365 English language articles published between 1997 and 2019 were identified. Following the analysis of titles, abstracts and keywords of these articles as well as the affiliations of authors, we categorized these articles according to their fields of research, types of research and applied research methods. Our findings indicate that the theoretical and methodological foundations of research on star architecture within the field of architecture are weak if compared to all other fields of study. Despite the significant number of articles within the architecture field, more than half of these articles do not receive any citations. Our findings confirm that the voices and perspectives of the architecture field contribute only marginally to the scholarly discussion of star architecture.
3D Metallic Plate Lens Antenna based Beamspace Channel Estimation Technique for 5G Mmwave Massive MIMO Systems

Beamspace channel estimation mechanism for massive MIMO (multiple input multiple output) antenna system presents a major process to compensate the 5G spectrum challenges caused by the proliferation of information from mobile devices. However, this estimation is required to ensure the perfect channel state information (CSI) for lower amount of Radio Frequency (RF) chains for each beam. In addition, phase shifter (PS) components used in this estimation need high power to select the beam in the desired direction. To overcome these limitations, in this work, we propose Regular Scanning Support Detection (RSSD) based channel estimation mechanism. Moreover, we utilise a 3D lens antenna array having metallic plate and a switch in our model which compensates the limitation of phase shifters. Simulation results show that the proposed RSSD based channel estimation surpasses traditional technique and SD based channel estimation even in lower SNR area which is highly desirable in the millimeter wave (mmWave) massive MIMO systems.
