description: Characterization of transport properties of porous media is increasingly relying on computational methods that require reconstruction of the media structure. We present a simple method of constructing the 3D surface of fibrous porous media - the gas diffusion layer (GDL) used as the porous electrode in PEM fuel cells. The method is based on extending the depth-of-field on the whole attainable thickness of the GDL. A series of images of the GDL sample is recorded by the sequential movement of the sample with respect to the microscope focus. Different layers of the surface of the sample appear in focus in the different images in the series. The indexed series of the in-focus portions of the sample surface is combined into one sharp 2D image and interpolated into the 3D surface representing the surface of an original GDL sample. The method uses a conventional upright stage microscope that is operated manually, the inexpensive Helicon Focus software, and the open source MeshLab software. The accuracy of the reconstruction of the image features was found to be ~ 1% for probing depth of ~ 100 um with the corresponding image acquisition time being ~ 10 min. Applying this method we found that: i) this technique is able to reproduce 3D-projection of the GDL structure for a depth of ~ 50-100 um, ii) the depth of the deepest channel in the GDL can be as much as ~ 100-160 um, for GDL samples with a thickness ~ 200 um.

The Functions of Social Interaction in the Knowledge-Creative Economy: Between Co-Presence and ICT-Mediated Social Relations

Publisher: name: Sociologica
Year: 2019
Subjects: social interactions; co-presence; ICT-mediated interactions; knowledge-creative workers; Milan

description: This article investigates the role and functions of interaction among knowledge-creative workers in Milan. While a large body of literature supports the relevance of co-presence for the building of social capital in creative scenes, a growing body of empirical and theoretical research shows in fact that, under certain circumstances, social relations mediated by digital tools are equally important. The extent to which professionals in these industries are embedded in “spaces” which are physical as well as digital, and how these have come to be so, remains nevertheless an under-explored research question. Building on findings from two distinct qualitative researches on knowledge-creative workers in Milan, undertaken in 2008 and 2011-13, it is here argued that knowledge-creative professionals are embedded in a wider “space” of relations where exchanges mediated via ICTs productively intertwine with face-to-face interaction to determine new ways of searching for jobs and practicing work. The paper highlights what changes when proximity becomes physical and digital as a mixture of face-to-face and ICT-mediated interaction, and discusses contradictions and implications of their blending, showing the necessity to overcome the rigid distinction between face-to-face and digital interaction that still characterises the empirical study of knowledge-creative economies.

description: N-nitrosodimethylamine (NDMA) is a disinfection byproduct that forms at the presence of an organic nitrogen precursor. Doxylamine, an antihistaminic pharmaceutical, is a precursor of NDMA and has been shown to form NDMA in the presence of chloramine. In this study, the effect of Doxylamine as an NDMA precursor has been further studied during chloramination. The end product and byproducts during chloramination were investigated using a high-resolution mass spectrometer by taking samples at different time intervals. Results suggest that NDMA is not the only end product forming during chloramination of Doxylamine and several transformation products that do not end up as NDMA may form. A group of these transformation products have been selected based on their relative amounts during chloramination with time and notated as Focus Tentative Transformation Products (FTTPn). The identification of these byproducts will make it easier to study the conditions during chloramination that may favor these “known” transformation products with the use of less sophisticated analytical instruments. Then, it might lead to the establishment of chloramination protocols that will minimize the formation of NDMA from its precursors.

description: Aims. Characterizing the interior structure of exoplanets is essential for understanding their diversity, formation, and evolution. As the interior of exoplanets is inaccessible to observations, an inverse problem must be solved, where numerical structure models need to conform to observable parameters such as mass and radius. This is a highly degenerate problem whose solution often relies on computationally expensive and time-consuming inference methods such as Markov chain Monte Carlo. Methods. We present ExoMDN, a machine-learning model for the interior characterization of exoplanets based on mixture density networks (MDN). The model is trained on a large dataset of more than 5.6 million synthetic planets below 25 Earth masses consisting of an iron core, a silicate mantle, a water and high-pressure ice layer, and a H/He atmosphere. We employ log-ratio transformations to convert the interior structure data into a form that the MDN can easily handle. Results. Given mass, radius, and equilibrium temperature, we show that ExoMDN can deliver a full posterior distribution of mass fractions and thicknesses of each planetary layer in under a second on a standard Intel i5 CPU. Observational uncertainties can be easily accounted for through repeated predictions from within the uncertainties. We used ExoMDN to characterize the interiors of 22 confirmed exoplanets with mass and radius uncertainties below 10 and 5%, respectively, including the well studied GJ 1214 b, GJ 486 b, and the TRAPPIST-1 planets. We discuss the inclusion of the fluid Love number k2 as an additional (potential) observable, showing how it can significantly reduce the degeneracy of interior structures. Utilizing the fast predictions of ExoMDN, we show that measuring k2 with an accuracy of 10% can constrain the thickness of core and mantle of an Earth analog to ≈13% of the true values.

description: In economic sociology, networks of relationships are seen as playing a fundamental role with respect to economic transactions, while interactions support such networks. Consequently, interactions appear as subordinated to the aim of conducting transactions, and as having an instrumental character. This comment argues that, if transactions are to be made possible, interactions among participants have to be conducted and understood as non-instrumental and autonomous.

description: We present a dynamic model for inhomogeneous viscoelastic media at finite strains. The model features a Kelvin--Voigt rheology, and includes a self-generated gravitational field in the actual evolving configuration. In particular, a fully Eulerian approach is adopted. We specialize the model to viscoelastic (barotropic) fluids and prove existence and a certain regularity of global weak solutions by a Faedo--Galerkin semi-discretization technique. Then, an extension to multi-component chemically reacting viscoelastic fluids based on a phenomenological approach by Eckart and Prigogine, is advanced and studied. The model is inspired by planetary geophysics. In particular, it describes gravitational differentiation of inhomogeneous planets and moons, possibly undergoing volumetric phase transitions.

description: We present the analysis of the HI content of a sample of early-type galaxies (ETGs) in low-density environments (LDEs) using the data set provided by the Arecibo Legacy Fast ALFA (ALFALFA) survey. We compare their properties to the sample in the Virgo cluster that we studied in a previous paper (di Serego Alighieri et al. 2007, Paper I). We have selected a sample of 62 nearby ETGs (V< 3000 km/s) in an area of the sky where the ALFALFA data are already available (8h -17). In both cases it is 10 times higher than that of the Virgo cluster. The presence of gas can be related to a recent star formation activity: 60% of all ETGs with HI have optical emission line ratios typical of star-forming galaxies and blue colours suggesting the presence of young stellar populations, especially in the dwarf subsample. We show that the HI detection rate of ETGs depends both on the environment and mass. The fraction of early-type systems with neutral hydrogen is higher in more massive objects when compared to early-type dwarfs. The ETGs in LDEs seem to have more heterogeneous properties than their Virgo cluster counterparts, since they are able to retain a cold interstellar gas component and to support star formation activity even at recent epochs.

description: Context. A major goal in the search for extraterrestrial life is the detection of liquid water on the surface of exoplanets. On terrestrial planets, volcanic outgassing is a significant source of atmospheric and surface water and a major contributor to the long-term evolution of the atmosphere. The rate of volcanism depends on the interior evolution and on numerous feedback processes between the atmosphere and interior, which continuously shape atmospheric composition, pressure, and temperature. Aims. We explore how key planetary parameters, such as planet mass, interior structure, mantle water content, and redox state, shape the formation of atmospheres that permit liquid water on the surface of planets. Methods. We present the results of a comprehensive 1D model of the coupled evolution of the interior and atmosphere of rocky exoplanets that combines central feedback processes between these two reservoirs. We carried out more than 280 000 simulations over a wide range of mantle redox states and volatile content, planetary masses, interior structures, and orbital distances in order to robustly assess the emergence, accumulation, and preservation of surface water on rocky planets. To establish a conservative baseline of which types of planets can outgas and sustain water on their surface, we focus here on stagnant-lid planets. Results. We find that only a narrow range of the mantle redox state around the iron-wüstite buffer allows the formation of atmospheres that lead to long-term habitable conditions. At oxidizing conditions similar to those of the Earth's mantle, most stagnant-lid planets end up in a hothouse regime akin to Venus due to strong CO2 outgassing. At more reducing conditions, the amount of outgassed greenhouse gases is often too low to keep surface water from freezing. In addition, Mercury-like planets with large metallic cores are able to sustain habitable conditions at an extended range of orbital distances as a result of lower volcanic activity.

Impedance compensation methods in wireless power transfer systems under variable coupling conditions
Creators: name: Ahmadi, Masoud
Publisher: name: University of British Columbia
Year: 2023

description: Wireless power transfer (WPT) systems use resonators that are carefully matched to deliver power at a particular transmission distance and operating frequency. Spatial variations in the position of the coupled resonators can significantly alter the input impedance of the system, leading to a direct impact on system efficiency and output power. The objective of this work is to investigate methods that can be used to maintain a constant input impedance in WPT systems with variable coupling conditions. The canonical filter theory approach serves as the central method for our investigation. We first highlight the the benefits of canonical filter prototypes in the systematic synthesis of matched inductive (IPT) and capacitive (CPT) power transfer systems with series-series and shunt-shunt resonator topologies. In the filter theory approach, impedance inverters are used to model the mutual coupling between coupled resonators. Using the inverter model, various impedance compensation methods can be derived. We first explore the application of an adaptive load resistance method in series and shunt CPT and IPT systems. Experimental examples of CPT and IPT systems are provided to explain how modifications to the load resistance can compensate for spatial variations. The results show that except for series IPT systems, the efficacy of the adaptive load method is constrained to a limited distance range. We then show how an adaptive load can be combined with frequency band switching. The method is then experimentally tested on a CPT system comprised of a class-E inverter, a six-plate CPT transmission link, and a class-E dual rectifier. We also explore adding frequency tracking and adaptive reactive matching elements to the adaptive load method to further extend the range of compensation. Our final study investigates using the filter theory approach for the synthesis of both singly- and doubly-terminated WPT networks. Since both models have been widely used for WPT systems, our study compares the spatial robustness of singly- and doubly-terminated capacitively-coupled WPT systems to evaluate whether one network has spatial advantages over the other.

description: We have calculated the cross section of the process e^+e^- \to γγ\to b\bar{b} in the littlest Higgs model with T parity (LHT). We find that, for the favorable parameters, the total cross section σ(e^+e^- \to γγ\to b\bar{b}) is sensitive to the breaking scale f, mixing parameter x_L, the masses of the mirror quarks m_{Hi}, and the relative correction of the LHT model is a few percent to dozens of percent. The cross section is significantly larger than the corresponding results in the standard model and in the other typical new physics models. Therefore the prediction in the LHT model is quite different from the predictions in other new physics models and such a process is really interesting in searching for the signs of the LHT model.

To conclude, I shall attempt to draw up a balance sheet between its contrasting contributions to contemporary political life in Europe. To accomplish this, I will have to speak “generically” and, therefore, to ignore or set aside the traits populism has had and the outcomes it has produced in specific cases. I begin with the (hazardous) position that it can be good or bad for democracy… depending. And I will finally try to address the issue of the conditions under which it is more likely to harm or benefit the polity in which it has emerged.

description: Only a few molecular clouds in the Solar Neighborhood exhibit the formation of only low-mass stars. Traditionally, these clouds have been assumed to be supported against more vigorous collapse by magnetic fields. The existence of strong magnetic fields in molecular clouds, however, poses serious problems for the formation of stars and of the clouds themselves. In this {\em Letter}, we review the three-dimensional structure and kinematics of Taurus --the archetype of a region forming only low-mass stars-- as well as its orientation within the Milky way. We conclude that the particularly low star-formation efficiency in Taurus may naturally be explained by tidal forces from the Galaxy, with no need for magnetic regulation or stellar feedback.

Subjects: Bourdieu through Gramsci; Capitalism; Intellectuals; Public Sociology; Social Movements; Sociological Imagination; Theorizing

description: In this conversation, Michael Burawoy discusses how he discovered the sociology of Gramsci in radically diverse contexts — from a vibrant post-colonial Zambia to Analytical Marxism in Chicago. The British sociologist reconnects the travels of these debates to contemporary public sociology, updating Gramsci’s key sociological concepts with the critical scholarship of Pierre Bourdieu, the social anthropology of Jaap Van Velsen and Raja Jayaraman, and the political economy of Karl Polanyi. These somehow real and imaginary conversations with social theorists bring Burawoy to stress the importance of reflexivity in sociological research. This means that sociological imagination is fostered through a constant dialectical relation between the art of theorizing and the “concrete phantasies” of social movements, which are well exemplified in Wright’s “real utopias.” Moreover, in Burawoy’s view, a new “Modern Prince” is urgently needed today and it is a public sociology which recognizes the mission of his critical knowledge against marketization.

description: The threshold transverse response functions R_T(q,omega) for 3He and 3H are calculated using the AV18 nucleon-nucleon potential, the UrbanaIX three-body force, and the Coulomb potential. Final states are completely taken into account via the Lorentz integral transform technique. Consistent two-body pi- and rho-meson exchange currents as deduced using the Arenhövel-Schwamb technique are included. The convergence of the method is shown and a comparison of the corresponding MEC contribution is made to that of a consistent MEC for the meson theoretical r-space BonnA potential. The response R_T is calculated in the threshold region at q=174, 324, and 487 MeV/c and compared with available data. The strong MEC contributions in the threshold region are nicely confirmed by the data at q=324 and 487 MeV/c although some differences between theoretical and experimental results remain. A comparison is also made with other calculations, where the same theoretical input is used. The agreement is generally rather good, but leaves also some space for further improvement.

description: In this paper we have investigated on the reliability of streams for a VoD system. The objective of the paper is to maximize the availability of streams for the peers in the VoD system. We have achieved this by using data replication technique in the peers. Hence, we proposed a new data replication technique to optimally store the videos in the peers. The new data replication technique generates more number of replicas than the existing techniques such as random, minimum request and maximize hit. We have also investigated by applying the CTMC model for the reliability of replications during the peer failures. Our result shows that the mean lifetime of replicas are more under various circumstances.

Assessing the contributions of visual and motor experience to action prediction skill in baseball
Creators: name: Besler, Zachary Andrew
Publisher: name: University of British Columbia
Year: 2023

description: Both visual and motor experiences impact action prediction, yet through potentially different mechanisms. Having physical experience with an action is thought to engage motor simulative processes, potentially activating the watcher’s motor system in an effector specific manner, aiding prediction. Leveraging baseball’s unique specialization demands, we assessed pitch discrimination in athletes with predominantly visual experience (hitters, n = 41) and motor experience (pitchers, n = 42; 9 left-handed). Videos of right-handed (RH) pitches, cut at or after ball release, of three different pitches, were used to assess pitch prediction accuracy. Two versions of each video clip were shown; the original RH clips were “flipped” to make the pitcher appear to throw left-handed (LH). Pitchers and hitters had reliable responses and showed high accuracy (~70%) and discriminability. Pitchers were more discriminatory than hitters (d prime) when contrasting two pitch types with the same initial trajectory and speed, but different postural cues (curveballs and changeups). Compared to hitters, pitchers also showed a trend for higher accuracy in “release-point” conditions, where only postural information was available. Accuracy was high on both left and right videos, but only LH pitchers showed a LH video advantage (although at release point, there were effector specific advantages for LH and RH pitchers). Because pitchers did not differ in accuracy from hitters, despite a lack of visual experience, this suggests that their motor experience aided predictions. However, there was only partial support for a simulation explanation (based on effector specificity).

description: Anaerobic ponds have the potential to contribute to low carbon wastewater treatment, however are currently restricted by long hydraulic residence time (HRT) which leads to large land requirements. A two-stage anaerobic pond (SAP) design was trialled against a single-stage control (CAP) over four HRTs down to 0.5 days, to determine the lowest HRT at which the ponds could operate effectively. No statistical differences were observed in particulate removal between the ponds over all four HRTs, suggesting solids loading is not a critical factor in AP design. Significantly higher biogas production rates were observed in the SAP than the CAP at 1.5 d and 1.0 d HRT, and microbial community profiling suggests the two-stage design may be facilitating spatial separation of the anaerobic digestion process along reactor length. Hydrogenotrophic methanogensis dominated over aceticlastic, with acetate oxidisation a likely degradation pathway. Experimental tracer studies were compared to CFD simulations, with the SAP showing greater hydraulic efficiency, and differences more pronounced at shorter HRTs. Greater flow recirculation between baffles was observed in CFD velocity profiles, demonstrating baffles can dissipate preferential flow patterns and increase effective pond volume, especially at high flow rates. The study demonstrates the potential of APs to be operated at shorter HRTs in psychrophilic conditions, presenting an opportunity for use as pre-treatments (in place of septic tanks) and primary treatment for full wastewater flows. Two-stage designs should be investigated to separate the stages of the anaerobic digestion process by creating preferential conditions along the pond length.

description: We compute the primordial mirror helium He' mass fraction emerging from Big Bang nucleosynthesis in the mirror sector of particles in the presence of kinetic mixing between photons and mirror photons. We explore the kinetic mixing parameter (epsilon) values relevant for cosmology and which are also currently probed by the dark matter direct detection experiments. In particular, we find that for epsilon \sim 10^{-9}, as suggested by the DAMA/Libra and other experiments, a large He' mass fraction (Y_{He'} \approx 90%) is produced. Such a large value of the primordial He' mass fraction will have important implications for the mirror dark matter interpretation of the direct detection experiments, as well as for the study of mirror star formation and evolution.

description: The present study for the first time manifests the outstanding potential of amine grafted magnetic graphene oxide (m-GO-NH2) synthesized from Typha latifolia stems for mercury (Hg (II)) and 2,4,6-trinitrophenol (TNP) removal. The adsorption performance of m-GO-NH2 was apprized by considering the impact of the contact time (0–120 min), pH (2–9), adsorbent dose (5–40 mg), and adsorbate concentration (10–50 mg/L). The maximum Hg (II) and TNP removals (∼ 100%) were obtained using 30 mg adsorbent dose in 90 and 75 min, respectively. The best performance of m-GO-NH2 was observed at pH of 7, 20 mg/L Hg (II), and pH of 2, 30 mg/L TNP. According to the Brunauer–Emmett–Teller (BET) analysis, the surface area of GO was 34.81 m2/g and the simultaneous micro and mesoporosity was observed. Regarding the thermodynamic studies, the adsorption procedure was spontaneous and endothermic for Hg (II) followed Redlich-Peterson (R-P) and Freundlich isotherm equations while it was exothermic for TNP, well fitted with Langmuir and R-P isotherms. Kinetic data also indicated a good correlation with pseudo-second-order model. The highest adsorption capacity was estimated as 107.33 and 105.2 mg/g for Hg (II) and TNP, respectively. Accordingly, the proposed m-GO-NH2 can be a promising adsorbent for the elimination of metal and organic contaminants.

description: Angle Resolved Photoemission Spectroscopy (ARPES) probes the momentum-space electronic structure of materials, and provides invaluable information about the high-temperature superconducting cuprates. Likewise, the cuprate real-space, inhomogeneous electronic structure is elucidated by Scanning Tunneling Spectroscopy (STS). Recently, STS has exploited quasiparticle interference (QPI) - wave-like electrons scattering off impurities to produce periodic interference patterns - to infer properties of the QP in momentum-space. Surprisingly, some interference peaks in Bi_{2}Sr_{2}CaCu_{2}O_{8+δ} (Bi-2212) are absent beyond the antiferromagnetic (AF) zone boundary, implying the dominance of particular scattering process. Here, we show that ARPES sees no evidence of quasiparticle (QP) extinction: QP-like peaks are measured everywhere on the Fermi surface, evolving smoothly across the AF zone boundary. This apparent contradiction stems from different natures of single-particle (ARPES) and two-particle (STS) processes underlying these probes. Using a simple model, we demonstrate extinction of QPI without implying the loss of QP beyond the AF zone boundary.

description: Informal learning materials for individual and team nature experiences. The materials are writing prompts and poems. The prompts were created to support someone writing before, during, and after a planned nature experience as a way to encourage reflection and to celebrate and share nature's events and stories. The written (provided as word documents) and audio-visual (provided as .mp4s) poems were created by Stephanie Januchowski-Hartley (Imagine), Ioanna (Daphne) Giannoulatou (Watching a Window), and Merryn Thomas (This Place). The audio-visual poems were produced by Ioanna (Daphne) Giannoulatou and include images by each of the three authors. The poems in the learning materials were written from the authors' responses to questions (those in the word document: "WritingPrompts-Before-During-After-DiglisWeir") before, during, and after their visit to an underwater viewing gallery that looks into one of the United Kingdom's largest fish passes at Diglis Weir in the River Severn.
