Authors: Servi Michaela , Buonamici Francesco , Puggelli Luca , Volpe Yary 
Published: October 2020

AbstractThe objective of this study is to establish a new methodology for the metrological characterization of interactive multi-camera systems. In the case of 3D system highly adapted to specific needs the accuracy evaluation cannot be performed using standard state-of-the-art techniques. To this end, the metrological characterization techniques used in the literature were investigated in order to define a new methodology that can be adjusted to each device by making the appropriate modifications. The proposed strategy is adopted for the metrological characterization of a new interactive multi-camera system for the acquisition of the arm.
Online detection of offsets in GPS time series
Authors: Nunnari Giuseppe , Cannavó Flavio 
Published: October 2020

AbstractThis paper deals with the online offset detection in GPS time series recorded in volcanic areas. The interest for this problem lies in the fact that an offset can indicate the opening of eruptive fissures. A Change Point Detection algorithm is applied to carry out, in an online framework, the offset detection. Experimental results show that the algorithm is able to recognize the offset generated by the Mount Etna eruption, occurred on December 24, 2018, with a delay of about 4 samples, corresponding to 40 min, compared to the best offline detection. Furthermore, analysis of the trade-off between success and false alarms is carried out and discussed.
Evaluation of cloud computing resource scheduling based on improved optimization algorithm
Authors: Yu Huafeng 
Published: October 2020

AbstractCloud computing, as a new computing mode in recent years, has been pursued by many users who have computational requirements, and the service quality of cloud computing depends largely on the efficiency of resource scheduling. In this study, an improved particle swarm optimization (IPSO) algorithm was proposed to improve the efficiency of resource scheduling, and simulation experiments were carried out on the IPSO algorithm and the traditional particle swarm optimization using CloudSim simulation platform. The phenomenon of premature appeared with the increase of the number of iterations, and the globally optimal solution was not found. The IPSO algorithm was more efficient in exploring the globally optimal solution, and the phenomenon of premature did not appear. As the number of tasks increased, the operation time of both algorithms increased, but the IPSO algorithm increased more slowly. The IPSO algorithm had more advantages when there were a large amount of tasks. Virtual machines in the two algorithms had different loads, and the load of the virtual machine in the IPSO algorithm was more balanced.
Diagnostics Based on Continuous Scanning LDV Measurements and RASTAR Analysis Method
Authors: Di Maio D. , Bruinsma S. , Tinga T. 
Published: October 2020

AbstractThis paper presents a technique for rapid diagnostics of structural integrity that exploits spectral sidebands measured by the continuous scanning LDV (CSLDV) measurement method. Structural integrity can be monitored by Operational Deflection Shapes ODSs, which can be quickly measurable at any excitation frequency when a laser continuously scans a vibrating surface. The LDV output time series is an amplitude modulated signal, and its spectral lines are used for recovering polynomial coefficients which build a polynomial function describing a deflection shape. The process of conversion from the time series to a polynomial function can be biased by measurement and analysis uncertainty which eventually will affect the quality of recovered ODS. This paper will show that an effective, rapid and straightforward diagnostics can be yielded by direct analysis of the spectral sidebands without the need to be transformed into polynomial coefficients. The Relative Amplitude of the Sidebands to the Total Amplitude Reference (RASTAR) method is an indicator that exploits the relative amplitude of the sidebands against a datum reference. The relative magnitudes of the sidebands will not change in the absence of any the structural change, and it is independent of the vibration response amplitudes set for the measurements. Such diagnostic method suits maintenance operations of structures which could be quickly scanned by an SLDV system providing an indicative level of structural integrity over the number of duty cycles.

Abstract

Introduction:
Urothelial carcinoma (UCC) develops in both humans and dogs and tracks to regions of high industrial activity. We hypothesize that dogs with UCC may act as sentinels for human urothelial carcinogen exposures. The aim of this pilot study was to determine whether healthy people and dogs in the same households share urinary exposures to potentially mutagenic chemical carcinogens.

Methods:
We measured urinary concentrations of acrolein (as its metabolite 3-HPMA), arsenic species, 4-aminobiphenyl, and 4-chlorophenol (a metabolite of the phenoxyherbicide 2,4-D) in healthy dogs and their owners. We assessed possible chemical sources through questionnaires and screened for urothelial DNA damage using the micronucleus assay.

Results:
Biomarkers of urinary exposure to acrolein, arsenic, and 4-chlorophenol were found in the urine of 42 pet dogs and 42 owners, with 4-aminobiphenyl detected sporadically. Creatinine-adjusted urinary chemical concentrations were significantly higher, by 2.8- to 6.2-fold, in dogs compared to humans. Correlations were found for 3-HPMA (r = 0.32, P = 0.04) and monomethylarsonic acid (r = 0.37, P = 0.02) between people and their dogs. Voided urothelial cell yields were inadequate to quantify DNA damage, and questionnaires did not reveal significant associations with urinary chemical concentrations.

Conclusions:
Healthy humans and pet dogs have shared urinary exposures to known mutagenic chemicals, with significantly higher levels in dogs. Higher urinary exposures to acrolein and arsenic in dogs correlate to higher exposures in their owners. Follow-up studies will assess the mutagenic potential of these levels in vitro and measure these biomarkers in owners of dogs with UCC.
Learning socio-organizational network structure in buildings with ambient sensing data
Authors: Sonta Andrew , Jain Rishee K. 
Published: October 2020

AbstractWe develop a model that successfully learns social and organizational human network structure using ambient sensing data from distributed plug load energy sensors in commercial buildings. A key goal for the design and operation of commercial buildings is to support the success of organizations within them. In modern workspaces, a particularly important goal is collaboration, which relies on physical interactions among individuals. Learning the true socio-organizational relational ties among workers can therefore help managers of buildings and organizations make decisions that improve collaboration. In this paper, we introduce the Interaction Model, a method for inferring human network structure that leverages data from distributed plug load energy sensors. In a case study, we benchmark our method against network data obtained through a survey and compare its performance to other data-driven tools. We find that unlike previous methods, our method infers a network that is correlated with the survey network to a statistically significant degree (graph correlation of 0.46, significant at the 0.01 confidence level). We additionally find that our method requires only 10 weeks of sensing data, enabling dynamic network measurement. Learning human network structure through data-driven means can enable the design and operation of spaces that encourage, rather than inhibit, the success of organizations.
CONNECTIVITY PROPERTIES OF MCKAY QUIVERS
Authors: BROWNE HAZEL 
Published: October 2020

AbstractWe present several results on the connectivity of McKay quivers of finite-dimensional complex representations of finite groups, with no restriction on the faithfulness or self-duality of the representations. We give examples of McKay quivers, as well as quivers that cannot arise as McKay quivers, and discuss a necessary and sufficient condition for two finite groups to share a connected McKay quiver.
UNIQUENESS OF EXTENDABLE TEMPERATURES
Authors: WATSON NEIL A. 
Published: October 2020

AbstractLet E and D be open subsets of

$\mathbb {R}^{n+1}$
such that

$\overline {D}$
is a compact subset of E, and let v be a supertemperature on E. A temperature u on D is called extendable by v if there is a supertemperature w on E such that

$w=u$
on D and

$w=v$
on

$E\backslash \overline D$
. From earlier work of N. A. Watson, [‘Extendable temperatures’, Bull. Aust. Math. Soc.100 (2019), 297–303], either there is a unique temperature extendable by v, or there are infinitely many; a necessary condition for uniqueness is that the generalised solution of the Dirichlet problem on D corresponding to the restriction of v to

$\partial _eD$
is equal to the greatest thermic minorant of v on D. In this paper we first give a condition for nonuniqueness and an example to show that this necessary condition is not sufficient. We then give a uniqueness theorem involving the thermal and cothermal fine topologies and deduce a corollary involving only parabolic and coparabolic tusks.
Seventeen Centuries of Sin: The Christian Past in Antebellum Slavery Debates
Authors: Gutacker Paul 
Published: October 2020

AbstractHistorians of American religion generally agree that religious debates over slavery were characterized by a reliance on the plain meaning of the Bible. According to the conventional wisdom, antebellum Americans were uninterested in or even overtly hostile to tradition and church history. However, a close study of pro- and antislavery literature complicates this picture of ahistorical biblicism. For some defenders of slavery, not merely the Bible but also Christian tradition supported their position, and these Catholics, Episcopalians, Presbyterians, Methodists, and Baptists mined the past for examples of Christian slaveholding. On the other hand, both white and Black antislavery authors used religious history to bolster their cases against the peculiar institution, with African Americans leading the way in developing an antislavery account of the Christian past. The previously unnoticed historical dimensions of religious arguments over slavery prove central to understanding why these debates failed, while also modifying how we conceive of scripture, tradition, and religious authority in nineteenth-century America. Arguments over slavery show that religious Americans—even many who claimed to be biblicists—did not read the Bible alone but always alongside and in relation to other texts, traditions, and interpreters.
Freedom in the Congregation? Culture Wars, Individual Rights, and National Churches in Switzerland (1848–1907)
Authors: Scholl Sarah 
Published: October 2020

AbstractThis paper aims to examine political, ecclesiastic, and theological changes in Switzerland during the time of the nineteenth-century culture wars. It analyzes the reforms of the churches undertaken during that period in correlation with the evolution of various social and cultural elements, in particular the ever-greater confessional diversity within the territory and the demand for religious freedom. After an initial general accounting of the history of Swiss institutions (state, Catholic, and Protestant national churches), the article explores an example of a liberal church reform that took place in Geneva in 1873: the creation of a Catholic Church defined simultaneously as Christian, national, liberal, and related to the German Old Catholic movement. It fashioned a new community in keeping with the idea that freedom of conscience should be implemented within the church, thereby meeting strong resistance from Roman Catholics. The article closes with a return to the broader Swiss context, arguing that freedom of belief and of worship was finally enshrined in the 1874 Swiss constitution as a result of the growing divisions among Christians over the compatibility of liberal values with Christian theology and the subsequent rise of a new confessionalism.

SummaryThis study was carried out to compare the efficacy of different methods to activate buffalo A + B and C + D quality oocytes parthenogenetically and to study thein vitrodevelopmental competence of oocytes and expression of some important genes at the different developmental stages of parthenotes. The percentage of A + B oocytes (62.16 ± 5.06%, range 53.8–71.3%) was significantly higher (P <0.001) compared with that of C + D oocytes (37.8 ± 5.00%, range 28.6–46.1%) retrieved from slaughterhouse buffalo ovaries. Among all combinations, ethanol activation followed by culture in research vitro cleave medium gave the highest cleavage and blastocyst yields for both A + B and C + D grade oocytes. Total cell numbers, inner cell mass/trophectoderm ratio and apoptotic index of A + B group blastocysts were significantly different (P< 0.05) from their C + D counterpart. To determine the status of expression patterns of developmentally regulated genes, the expression of cumulus–oocyte complexes, fertilization, developmental competence and apoptotic-related genes were also studied in parthenogenetically produced buffalo embryos at different stages, and indicated that the differential expression patterns of the above genes had a role in early embryonic development.
The Thermal Evolution of Mercury Over the Past ∼4.2 Ga as Revealed by Relaxation States of Mantle Plugs Beneath Impact Basins

Published: October 2020

AbstractWe investigated the relaxation states of 11 large impact basins on Mercury based on an updated crustal thickness map, finding that the pre‐Tolstojan basins have comparable instead of varied relaxation states, suggesting that Moho temperature (TempMoho ) did not decrease substantially from ∼4.2 to 3.8 Ga. At the same time, mantle uplift beneath the Caloris basin is the least degraded, therefore implying a sharp decrease of TempMoho ∼ 3.8 Ga. These findings contrast with our thermal evolution models that predict a fast decrease of TempMoho between ∼4.2 and 3.8 Ga. Therefore, the discrepancies in the cooling rate suggest that the relatively elevated bombardment history between ∼4.2 and 3.8 Ga might have input additional energy to Mercury and substantially decreased the cooling rate.

AbstractHow the solar electromagnetic energy entering the Earth's atmosphere varied since preindustrial times is an important consideration in the climate change debate. Detrimental to this debate, estimates of the change in total solar irradiance (TSI) since the Maunder minimum, an extended period of weak solar activity preceding the industrial revolution, differ markedly, ranging from a drop of 0.75 W m−2 to a rise of 6.3 W m−2. Consequently, the exact contribution by solar forcing to the rise in global temperatures over the past centuries remains inconclusive. Adopting a novel approach based on state‐of‐the‐art solar imagery and numerical simulations, we establish the TSI level of the Sun when it is in its least‐active state to be 2.0 ± 0.7 W m−2 below the 2019 level. This means TSI could not have risen since the Maunder minimum by more than this amount, thus restricting the possible role of solar forcing in global warming.

AbstractWe have developed the automatic detection scheme for upper hybrid resonance (UHR) frequency using a convolutional neural network (CNN) from the electric field spectra obtained by the plasma wave experiment (PWE) aboard Arase. In this paper, we investigate the practical capability of this scheme in terms of actual scientific use case. We find that the average error rate is below 7.8% when the wave frequency is above 30 kHz and the wave spectral intensity is less than 10−5 mV 2/m2/Hz. About 91% of the data obtained by the high‐frequency analyzer (HFA) aboard the Arase satellite satisfies these conditions. To improve the accuracy of the determined UHR frequencies in a wide frequency range, we used another receiver, the onboard frequency analyzer (OFA), which enables us to detect low‐frequency UHR emissions. We confirmed that the averaged error rate derived by the OFA spectra becomes better than that derived from the HFA spectra in a frequency range below 20 kHz. We report the performance of the UHR frequency determination under the different geomagnetic conditions. We find that the UHR frequency can be determined with good accuracy using the CNN from the frequency‐time diagram both during geomagnetically quiet and disturbed conditions. We conclude that the CNN‐based UHR frequency determination is a reliable method to derive the electron density along the satellite orbit through observations of UHR frequencies, and this method contributes to studies on dynamics of the plasmasphere.

AbstractSub‐ion magnetic holes are rich in the terrestrial plasma sheet and magnetosheath. Here, we statistically investigate 60 sub‐ion magnetic holes in the solar wind at 1 AU using the high‐resolution data measured by the Magnetospheric Multiscale mission. We find that they are observed with a duration of 0.1 –0.5 s, and the lengths of their cross‐section are ~0.1 –0.6 ion gyroradius. These structures prefer to occur in the slow solar wind with a weak ambient magnetic field strength. They also prefer to occur in the marginally mirror stable or unstable environments. Electron vortices as well as an enhancement of the electron perpendicular temperature and electron fluxes at ~90° pitch angle tend to be observed inside some magnetic holes with a large ambient magnetic field strength. By contrast, there are no clearly observational electron vortices as well as the electron fluxes at ~90° pitch angle inside some magnetic holes with a weak ambient magnetic strength. The current density with a value of ~10 –50 nA/m2 reveals that the corresponding maximum electron velocity is <10 km/s inside some magnetic holes, lower than the level of the observational electron velocity noise, which prevents the detection of the weak electron vortex. We suggest that electron vortices exist inside all the sub‐ion magnetic holes in the solar wind. The generation of these sub‐ion magnetic holes might be explained by the electron magnetohydrodynamics soliton and the electron vortex magnetic hole.
Tidal Modulation of Buoyant Flow and Basal Melt Beneath Petermann Gletscher Ice Shelf, Greenland

Published: October 2020

AbstractA set of collocated, in situ oceanographic and glaciological measurements from Petermann Gletscher Ice Shelf, Greenland, provides insights into the dynamics of under‐ice flow driving basal melting. At a site 16 km seaward of the grounding line within a longitudinal basal channel, two conductivity‐temperature (CT) sensors beneath the ice base and a phase‐sensitive radar on the ice surface were used to monitor the coupled ice shelf‐ocean system. A 6 month time series spanning 23 August 2015 to 12 February 2016 exhibited two distinct periods of ice‐ocean interactions. Between August and December, radar‐derived basal melt rates featured fortnightly peaks of ∼15 m yr−1 which preceded the arrival of cold and fresh pulses in the ocean that had high concentrations of subglacial runoff and glacial meltwater. Estimated current speeds reached 0.20 – 0.40 m s−1 during these pulses, consistent with a strengthened meltwater plume from freshwater enrichment. Such signals did not occur between December and February, when ice‐ocean interactions instead varied at principal diurnal and semidiurnal tidal frequencies, and lower melt rates and current speeds prevailed. A combination of estimated current speeds and meltwater concentrations from the two CT sensors yields estimates of subglacial runoff and glacial meltwater volume fluxes that vary between 10 and 80 m3 s−1 during the ocean pulses. Area‐average upstream ice shelf melt rates from these fluxes are up to 170 m yr−1, revealing that these strengthened plumes had already driven their most intense melting before arriving at the study site.

AbstractDysregulation of free acid metabolism is a major contributor to the development of insulin resistance and diabetes. Mitochondrial trifunctional enzyme subunit (MTPα) has a critical role in fatty acid β-oxidation. However, the association between MTPα and insulin resistance is not definitively known. Here, we aimed to determine how MTPα affects insulin resistance. We tested how MTPα affected glucose uptake in insulin-resistant 3T3-L1 adipocytes and white adipose tissue (WAT) of db/db diabetic mice. We also measured how acetylation and ubiquitylation modifications regulated MTPα activation and stability, using quantitative real-time polymerase chain reactions, immunoblotting, and immunoprecipitation. We found that MTPα overexpression promoted glucose uptake via Glut4 translocation to the plasma membrane in 3T3-L1 adipocytes. Moreover, MTPα upregulation decreased glycemia in db/db mice. Deacetylation increased MTPα protein stability and its ability to reduce insulin resistance. The activation of SIRT1, a major deacetylase, prevented MTPα degradation by decreasing its acetylation in adipocytes. Our study demonstrates a new role for MTPα in reducing insulin resistance. Acetylation and ubiquitylation modifications of MTPα were crucial to regulating its function in glucose metabolism.
