description: We report on a state characterized by a zero differential resistance observed in very high Landau levels of a high-mobility two-dimensional electron system. Emerging from a minimum of Hall field-induced resistance oscillations at low temperatures, this state exists over a continuous range of magnetic fields extending well below the onset of the Shubnikov-de Haas effect. The minimum current required to support this state is largely independent on the magnetic field, while the maximum current increases with the magnetic field tracing the onset of inter-Landau level scattering.

description: La linea ferroviaria della Matterhorn Gotthard Bahn, tra Stalden e Täsch, attraversa 20 zone interessate da processi valanghivi. Una delle zone di processo più critiche è rappresentata dalla zona di Blattbach, a sud del comune di St.Niklaus, dove i binari vengono sepolti dalle valanghe in media ogni 10/15 anni. Per questo è stata richiesta un’analisi dettagliata dei processi valanghivi al fine di mettere in atto una misura di intervento che rispetti i seguenti obiettivi: 1. Protezione contro le valanghe trentennali 2. Protezione dalle colate detritiche/alluvioni trentennali 3. Limitare i tempi d’interruzione 4. Il rischio di morte individuale non deve superare il limite di 1x10-5 all'anno

description: We explore the thermal state of the neutron star in the Cassiopeia A supernova remnant using the recent result of Ho & Heinke (Nature, 462, 71 (2009)) that the thermal radiation of this star is well-described by a carbon atmosphere model and the emission comes from the entire stellar surface. Starting from neutron star cooling theory, we formulate a robust method to extract neutrino cooling rates of thermally relaxed stars at the neutrino cooling stage from observations of thermal surface radiation. We show how to compare these rates with the rates of standard candles -- stars with non-superfluid nucleon cores cooling slowly via the modified Urca process. We find that the internal temperature of standard candles is a well-defined function of the stellar compactness parameter $x=r_g/R$, irrespective of the equation of state of neutron star matter ($R$ and $r_g$ are circumferential and gravitational radii, respectively). We demonstrate that the data on the Cassiopeia A neutron star can be explained in terms of three parameters: $f_\ell$, the neutrino cooling efficiency with respect to the standard candle; the compactness $x$; and the amount of light elements in the heat blanketing envelope. For an ordinary (iron) heat blanketing envelope or a low-mass ($\lesssim 10^{-13}\,M_\odot$) carbon envelope, we find the efficiency $f_\ell \sim 1$ (standard cooling) for $x \lesssim 0.5$ and $f_\ell \sim 0.02$ (slower cooling) for a maximum compactness $x\approx 0.7$. A heat blanket containing the maximum mass ($\sim 10^{-8}\,M_\odot$) of light elements increases $f_\ell$ by a factor of 50. We also examine the (unlikely) possibility that the star is still thermally non-relaxed.

description: Il presente lavoro ha lo scopo indagare come vengono vissuti lo spazio fisico e virtuale delle interazioni e della socializzazione dagli allievi e dalle allieve di scuola media. Per sondare il ruolo e le dinamiche di questi spazi aggregativi è stata condotta una ricerca qualitativa improntata al focus group con una classe di terza media di Pregassona. In aggiunta all’analisi degli scambi avvenuti in questo contesto è stata fatta un’intervista con il direttore della scuola, Robert Rüegger. I dati raccolti mostrano che lo spazio fisico rappresenta il quadro di riferimento principale di socializzazione e che esso si sovrappone in modo marcato allo spazio d’interazione virtuale. Gli spazi aggregativi sono costituiti essenzialmente da spazi relativi al contesto sociale e territoriale della classe. Il gruppo classe stesso risulta essere il nucleo principale di socializzazione. La sfera sociale si allarga poi al contesto scolastico più generale e a quello di quartiere e comune. L’utilizzo del digitale non comporta un significativo aumento delle interazioni esterne al contesto di vita. Poiché si tende ad interessarsi a ciò che ci è affine, la maggioranza degli aspetti legati alla dimensione locale risultano in linea con la dimensione globale piuttosto che in conflitto con essa. Lo spazio vissuto dagli allievi e dalle allieve risulta essere sostanzialmente uno e indissociabile. Relatori: Marco Lupatini, Reto Torti.

description: Virtual Reality has evolved as a powerful, embedded and immersive technology medium to transform dating experiences. However, there is no rigorous CSCW research examining ‘dating’ in VR, despite social interaction being a serious topic of exploration. We aim to push the CSCW discourse on social interaction further by analyzing the dynamics of romantic reciprocality in a fully immersive VR application. Through a qualitative study of 30 participants in 15 pairs, we examine a customizable VR application ‘RecRoom’ as a dating technology medium to analyze how dimensions of interaction - including but not limited to voice, haptics and spatiality - influence dynamics of dating experiences. We employ Tinder as a contrasting chat based medium to situate and deepen our learnings about dating in VR. Our study finds VR allowing users to efficiently and effectively ‘gauge’ matches resulting in well informed decisions to meet (or not) virtual partners ’IRL’ or in real life than existing chat based mediums like Tinder. We believe this leads to improved experience of first dates.

description: Recently it has been discovered---contrary to expectations of physicists as well as biologists---that the energy transport during photosynthesis, from the chlorophyll pigment that captures the photon to the reaction centre where glucose is synthesised from carbon dioxide and water, is highly coherent even at ambient temperature and in the cellular environment. This process and the key molecular ingredients that it depends on are described. By looking at the process from the computer science view-point, we can study what has been optimised and how. A spatial search algorithmic model based on robust features of wave dynamics is presented.

Mechanisms of cardiac pacemaking and temperature-dependent depression of cardiac electrical excitation in the zebrafish (Danio rerio)
Creators: name: Marchant, James
Publisher: name: University of British Columbia
Year: 2021

description: The physiology of ectotherms is profoundly affected by the environmental temperature which governs the rate of physiological processes. Cardiac function, an essential function of all vertebrates, is no exception: during warming heart rate tracks temperature before declining at temperatures beyond maximum optimal temperature, ultimately collapsing with further warming. In fishes, like other vertebrates, intrinsic heart rate is set by pacemaker cells located in the sino-atrial node that spontaneously generate action potentials. At the cellular level, temperature-dependent deterioration of pacemaking mechanisms may contribute to the decline of cardiac function. Nevertheless, the mechanisms of pacemaking and their temperature-dependent deterioration remain elusive. Hence, I explored cardiac pacemaking mechanisms in zebrafish, as well as their relative thermal performance and limits. I validated blebbistatin as an effective excitation-contraction uncoupling agent that did not modify the cardiac action potential properties, thus providing an essential methodology for future cardiac pacemaking research enabling the direct recording of intracellular electrical activity of pacemaker cells. Using electrocardiograms, I confirmed that cardiac pacemaking involves two major mechanisms. Pharmacological blockade of hyperpolarization-activated cyclic nucleotide-gated (HCN) channels with zatebradine reduced heart rate by up to 60%, suggesting HCN channels play the major role in cardiac pacemaking. Likewise, sarcoplasmic reticulum (SR) calcium cycling was pharmacologically blocked using ryanodine and thapsigargin to block ryanodine receptors and SERCA pumps, respectively, which reduced heart rate by ~40%, suggesting the SR plays a secondarily important role in pacemaking. However, the combination of these pharmacological interventions did not completely stop the heartbeat, suggesting that either mammalian pharmacological agents are less effective in producing total Hcn block in zebrafish, perhaps due to isoform specificity. HCN4, the major HCN channel involved in mammalian pacemaking, was knocked out using CRISPR to explore its role in zebrafish cardiac pacemaking. Heart rate did not differ significantly between mutant and control fish at any test temperature, including fish treated with inhibitors of HCN channels or SR calcium cycling. Thus, alternative Hcn channels compensated for the knockout of Hcn4, presumably contributing to a higher thermal tolerance. In addition, mutant fish had a higher upper thermal tolerance than control fish when SR calcium cycling was inhibited.
Double-valuedness of the electron wave function and rotational zero-point motion of electrons in rings

description: I propose that the phase of an electron's wave function changes by $π$ when the electron goes around a loop maintaining phase coherence. Equivalently, that the minimum orbital angular momentum of an electron in a ring is $\hbar/2$ rather than zero as generally assumed, hence that the electron in a ring has azimuthal zero point motion. This proposal provides a physical explanation for the origin of electronic `quantum pressure', it implies that a spin current exists in the ground state of aromatic ring molecules, and it suggests an explanation for the ubiquitousness of persistent currents observed in mesoscopic rings.

description: Carrying out successful design workshops can be a challenging task. This can turn even more difficult, if one attempts to engage in more inclusive design workshops, where a broad range of user profiles are covered. If some of these profiles refer to people with impairments, things can get even more complicated. Furthermore, there are also associated challenges when trying to carry out something that is usually implemented as a face-to-face activity in an online format. This exploratory paper introduces a discussion on a few lessons learned from organising design workshops including both people with and without visual impairments. It also outlines our response to the situation created by the COVID-19 pandemic, which prevented us to engage in face-to-face design workshops. Based on feedback received from participants of a first in-person design workshop organised within one of our projects and on informal interviews carried out mainly over the phone to discuss ways to enhance the collaboration between people with and without visual impairments during such activities, we go on to introduce some relevant aspects that should be taken into consideration when planning inclusive design workshops. This is a preliminary contribution, meant to raise discussions on technology-mediated inclusive participatory design initiatives to further inform the development of a solid methodological contribution to CSCW.

description: The development of infrared observational facilities has revealed a number of massive stars in obscured environments throughout the Milky Way and beyond. The determination of their stellar and wind properties from infrared diagnostics is thus required to take full advantage of the wealth of observations available in the near and mid infrared. However, the task is challenging. This session addressed some of the problems encountered and showed the limitations and successes of infrared studies of massive stars.

description: Bi-intuitionistic logic is the conservative extension of intuitionistic logic with a connective dual to implication. It is sometimes presented as a symmetric constructive subsystem of classical logic. In this paper, we compare three sequent calculi for bi-intuitionistic propositional logic: (1) a basic standard-style sequent calculus that restricts the premises of implication-right and exclusion-left inferences to be single-conclusion resp. single-assumption and is incomplete without the cut rule, (2) the calculus with nested sequents by Gore et al., where a complete class of cuts is encapsulated into special "unnest" rules and (3) a cut-free labelled sequent calculus derived from the Kripke semantics of the logic. We show that these calculi can be translated into each other and discuss the ineliminable cuts of the standard-style sequent calculus.

The COV was calculated by dividing the SD by the mean of SUV values in the ROI. The three horizontal dot lines marked 10% and 15% COV levels. According to the 18F-FDG PET/CT protocol of Uniform Protocols for Imaging in Clinical Trials (UPICT), 10% and 15% were the recommendation of ideal and acceptance level for quality control. The routine-voxel OSEM (RVOSEM) and small-voxel BPL (SVB) groups with a penalty factor of 0.8 - 1.0 were all within 15% COV limit and had a majority proportion (more than 75% percentile) of the cases with a COV of <10%. The small-voxel OSEM (SVOSEM) group had 5 out of 24 (20.8%) cases with a COV of >15% in the liver and 6 out of 24 (25%) cases with a COV of >15% in the mediastinum. Supplementary table 2.

title: High-Magnification Digital Image Correlation Techniques for Aged Nuclear Fuel Cladding Testing
Creators: name: Hansen, Robert Scott
Publisher: name: Utah State University

description: Nuclear fuel cladding in light water reactors, often made of zirconium alloys, is naturally made more brittle by exposure to the water coolant during normal reactor operation. However, this embrittlement by zirconium hydrides changes the mechanical behavior of the cladding material, affecting how it will deform and what may cause it to fail. Because the cladding already has different properties in different material directions, mechanical testing also needs to be direction specific. In addition, to understand the effects that these microscale hydride features have, measurements of deforming cladding need to be at a microscale. This dissertation describes several high-magnification innovations and advancements in digital image correlation (DIC), a non-contact method for measuring displacement and strain of test specimens during experiments. First, a high-magnification UV lens is demonstrated to be capable of DIC measurements with improved spatial resolution and at high temperatures. Second, previously developed super resolution imaging techniques are applied to DIC measurements of directional ring test specimens, again improving resolution and measurement quality. Third, image capture settings are optimized to balance a tradeoff between poor depth of field and the diffraction of light, both of which cause blurred images and poorer DIC measurements. Fourth, several test arrangements are analyzed with computer modelling to determine the best method for directional tests of the cladding. Finally, the techniques are used to perform high-magnification tension tests for hydrided ring cladding specimens.

description: Video annotation and analysis is an important activity for teaching with and about audiovisual media artifacts because it helps students to learn how to identify textual and formal connections in media products. But school teachers lack adequate tools for video annotation and analysis in media education that are easy-to-use, integrate into established teaching organization, and support quick collaborative work. To address these challenges, we followed a design-based research approach and conducted qualitative interviews with teachers to develop TRAVIS GO, a web application for simple and collaborative video annotation. TRAVIS GO allows for quick and easy use within established teaching settings. The web application provides basic analytical features in an adaptable work space. Key didactic features include tagging and commenting on posts, sharing and exporting projects, and working in live collaboration. Teachers can create assignments according to grade level, learning subject, and class size. Our work contributes further insights for the CSCW community about how to implement user demands into developing educational tools.

description: Informational presentations in Graphics Interchange Format (GIF), have been commonly used to convey emotional, cultural, and non-verbal cues in computer-mediated communication. However, the usage and impact of animated GIFs in the sharing and consumption of procedural knowledge, such as how-to instructions, remains unclear. In this paper, we leverage an online collaborative procedural knowledge-sharing platform – wikiHow to investigate the roles of GIFs in the construction and editing of How-To tutorials and how multimodal tutorials impact learners’ perception and learning from the shared expositions. Through data analytics of archived editing histories, article content and user ratings of wikiHow pages, we found that tutorials consisting of multiple modalities, including animated GIFs and images in addition to text, in general introduced more edits and more textual content compared with text-only articles. When learners learned from these wikiHow tutorials, the tutorials with rich modalities also received higher usefulness evaluation from learners, and accumulated more success stories from the learners in following the tutorials to perform procedural tasks. We discuss the implications for future research on multimodal factors for collaborative procedural knowledge sharing.

description: Distance measurements of gamma-ray pulsars are challenging questions in present pulsar studies. The Large Area Telescope (LAT) aboard the Fermi gamma-ray observatory discovered more than 70 gamma-ray pulsars including 24 new gamma-selected pulsars which nearly have no distance information. We study the relation between gamma-ray emission efficiency ($η=L_γ/\dot E$) and pulsar parameters for young radio-selected gamma-ray pulsars with known distance information in the first gamma-ray pulsar catalog reported by Fermi/LAT. We have introduced three generation order parameters to describe gamma-ray emission properties of pulsars, and find the strong correlation of $η-ζ_3$ a generation order parameter which reflects $γ$-ray photon generations in pair cascade processes induced by magnetic field absorption in pulsar magnetosphere. A good correlation of $η-B_{\rm LC}$ the magnetic field at the light cylinder radius is also found. These correlations would be the distance indicators in gamma-ray pulsars to evaluate distances for gamma-selected pulsars. Distances of 25 gamma-selected pulsars are estimated, which could be tested by other distance measurement methods. Physical origin of the correlations may be also interesting for pulsar studies.

description: Participatory design (PD) is a meaningful approach to involve older adults into design; however, currently we lack understanding how to do such work online. In our paper, we report from a study where we organized 19 PD workshops online with older adults. We argue that to do so in a meaningful way, a mutually shaped understanding of older adults’ digital ecologies is at the core of organizing such PD processes. We present an empirical account of how digital ecologies of our older participants have become an issue to tackle in the online PD workshops. Further, we provide a solution, a mapping technique, and report from our efforts to evaluate it, that should help to overcome the situation when digital ecologies become a problem in PD online.

Year: 2021

description: In this note, we report on a qualitative design study in the field of machine learning (ML) and in particular on the sensemaking practices of ML developers as they interact with the interface of a novel adversarial AI method. This paper makes contributions to discourses on interpretable or explainable AI (XAI) systems through an empirical understanding of ML developers’ sensemaking practices. These findings make salient the concept of “explorability” as an alternative design metaphor for interactive AI systems – instead of a focus on explainability or interpretability as fixed qualities of AI systems, explorability focuses on emergent meanings and ways in which they might be enabled or constrained through practice.

description: We present an applied study in cancer genomics for integrating data and inferences from laboratory experiments on cancer cell lines with observational data obtained from human breast cancer studies. The biological focus is on improving understanding of transcriptional responses of tumors to changes in the pH level of the cellular microenvironment. The statistical focus is on connecting experimentally defined biomarkers of such responses to clinical outcome in observational studies of breast cancer patients. Our analysis exemplifies a general strategy for accomplishing this kind of integration across contexts. The statistical methodologies employed here draw heavily on Bayesian sparse factor models for identifying, modularizing and correlating with clinical outcome these signatures of aggregate changes in gene expression. By projecting patterns of biological response linked to specific experimental interventions into observational studies where such responses may be evidenced via variation in gene expression across samples, we are able to define biomarkers of clinically relevant physiological states and outcomes that are rooted in the biology of the original experiment. Through this approach we identify microenvironment-related prognostic factors capable of predicting long term survival in two independent breast cancer datasets. These results suggest possible directions for future laboratory studies, as well as indicate the potential for therapeutic advances though targeted disruption of specific pathway components.

title: A Content Analysis of Stereotyping of the American Indian in Selected Mass Media
Creators: name: Pratt, Michael
Publisher: name: Utah State University
Year: 1979

description: This study was conducted to see to what extent, if any, the American Indian was stereotyped. In three magazines, two aimed at the young reader and one for a specialized adult audience, two areas of the publications were content analyzed. First, all of the cartoons that dealt specifically with American Indians were surveyed and categorized. Next, all magazine articles about American Indians were collected, read thoroughly and placed into categories. The magazines were the "Boy's Life," "Jack and Jill", and the "Western Horseman".
To gather data on media presentations of Indians eight categories were used, they were: (1) Personal appearance, (2) Dress, (3) Communications, (4) Transportation, (5) Family dwellings, (6) Daily routines, (7) Intelligence, and (8) Names.
The study showed that the American Indian men presented in the stories and cartoons were dressed in buckskin leggings, wore a breechcloth, had long braided hair, wore feathers or war bonnets, moccasins and had painted faces. Generally, the magazines presented all Indian characters patterned after the plains Indian. In all of the cartoons where living conditions were portrayed, the Indians occupied teepees, hogans, log cabins or pueblo apartments. The Indians traveled on horses, and when communicating over long distances they used smoke signals or drumbeats. The Indian's everyday life was presented as spent in hunting for game for food, tending to animal herds, constructing clothes, shelter, and hunting weapons, and producing Indian handicrafts.
The stories and cartoons depicted the Indians as easily outwitted by a superior white man. The Indians were nomadic hunters in the stories. The stories and cartoons described the Indians in terms of life-styles prevelent over 150 years ago. No distinction was made among tribes, all Indians were cast the same. The Indians were characters who had names of animals or titles that were tagged on them by the white man. Squaw, papoose, buck and chief were general character names used in the stories and cartoons.

description: In this work the electric power system 330/110 kV was studied. The equipments of the electric power system, such as transformers and OHL, were selected. After that, a theoretical calculation of the steady state operation and calculation using the RastrWIN software was made, as well as the modes of on-peak and off-peak loads. The currents and voltages of a single phase short circuit were determined and vector diagrams were constructed. In the final part of the work, the dynamic stability of the system was investigated using the Dymola software and measures were taken to improve it.
La motricità fine fra i banchi di scuola

description: Diverse ricerche mostrano come le competenze di motricità fine influenzano in maniera importante il rendimento scolastico dell’allievo così come la sua vita quotidiana. Per questo motivo è anche compito degli insegnanti facilitare e garantire lo sviluppo di queste abilità fra le mura scolastiche. La motricità fine risulta essere una competenza fondamentale per quanto riguarda la capacità di scrittura e, nello specifico, la presa della matita. Nella presente ricerca, sono stati presi in analisi cinque casi ai quali sono state somministrate delle prove concernenti la presa della matita e la precisione del tratto di scrittura a seguito di un intervento mirato sull’attivazione della competenza di motricità fine. Lo scopo del presente lavoro era di osservare in che misura degli interventi sulla motricità fine influenzassero la presa della matita e la precisione del tratto dell’allievo. L’analisi dei dati raccolti non conferma completamente quanto ipotizzato: l’impugnatura degli allievi non ha subito miglioramenti ma, la precisione del tratto di scrittura, è progredito rispetto alle osservazioni ricavate all’inizio della ricerca.

description: The electronic structure of the new superconducting material LaNiPO experimentally probed by soft X-ray spectroscopy and theoretically calculated by the combination of local density approximation with Dynamical Mean-Field Theory (LDA+DMFT) are compared herein. We have measured the Ni L2,3 X-ray emission (XES) and absorption (XAS) spectra which probe the occupied and unoccupied the Ni 3d states, respectively. In LaNiPO, the Ni 3d states are strongly renormalized by dynamical correlations and shifted about 1.5 eV lower in the valence band than the corresponding Fe 3d states in LaFeAsO. We further obtain a lower Hubbard band at -9 eV below the Fermi level in LaNiPO which bears striking resemblance to the lower Hubbard band in the correlated oxide NiO, while no such band is observed in LaFeAsO. These results are also supported by the intensity ratio between the transition metal L2 and L3 bands measured experimentally to be higher in LaNiPO than in LaFeAsO, indicating the presence of the stronger electron correlations in the Ni 3d states in LaNiPO in comparison with the Fe 3d states in LaFeAsO. These findings are in accordance with resonantly excited transition metal L3 X-ray emission spectra which probe occupied metal 3d-states and show the appearance of the lower Hubbard band in LaNiPO and NiO and its absence in LaFeAsO.

Dialectica Interpretation with Marked Counterexamples

description: Goedel's functional "Dialectica" interpretation can be used to extract functional programs from non-constructive proofs in arithmetic by employing two sorts of higher-order witnessing terms: positive realisers and negative counterexamples. In the original interpretation decidability of atoms is required to compute the correct counterexample from a set of candidates. When combined with recursion, this choice needs to be made for every step in the extracted program, however, in some special cases the decision on negative witnesses can be calculated only once. We present a variant of the interpretation in which the time complexity of extracted programs can be improved by marking the chosen witness and thus avoiding recomputation. The achieved effect is similar to using an abortive control operator to interpret computational content of non-constructive principles.

description: When there are two classes, a majority vote can always be obtained with three labelers. Researchers can utilize this property to obtain a false sense of confidence in their ground truth labels. We demonstrate such a case with 3000 crowdsourced labels for an online hate dataset. Evaluating with percentage agreement, Gwet’s AC1, and Krippendorff’s alpha, results show that using more raters teases out the hidden nuances in raters’ preferences. We show that full agreement among the raters monotonically decreases from three raters (28.4%) to nine raters (19.5%). Ten raters have a higher agreement than any other number of raters, which supports the idea of increasing the number of raters for subjective labeling tasks. Nevertheless, while beneficial, increasing the number of raters cannot be considered as a fundamental solution to the issue of agreement in subjective crowdsourcing tasks, as even with ten raters, there is a non- negligible number of ties (4.11%). We suggest having a small sample of the data labeled by five or more raters to evaluate the stability of agreement among the raters.

description: We present a representative survey of the digital working conditions of 466 Danish knowledge workers. We provide data on 1) the hardware and software they use to accomplish their main job activities, 2) the strategies they use to personalise their software, and 3) their digital competences. Our results show that the average Danish knowledge worker primarily uses a laptop and a smartphone to accomplish their work; they use an average of four software applications, mostly developed by large US corporations; they infrequently personalise their software using built-in settings and rarely personalise using plugins, scripts, or reprogramming; they are most capable in using collaboration and communication tools, feel more comfortable formatting other worker’s digital content than creating their own, and are confident they can solve most technical issues. These results put into question the relevance of the long-standing Personal Computing dream envisioned by HCI pioneers, highlights the tensions between software applications and the digital sovereignty of the European continent, and emphasise the importance of including digital tools in our conceptualisation and regulation of working conditions.

description: Human beings have for ages domesticated animals which they have kept for companionship as pets. Originally man and his animals lived on scattered farms and ranches where pets had plenty of room to roam. As human social structures changed and people crowded into towns and cities, the matter of controlling one's pets in order to prevent their becoming the neighbor's pests became a serious concern. Next to fights over water rights in the west, perhaps the most frequent cause for contention was the control of one's pets.
Freely-Decaying, Homogeneous Turbulence Generated by Multi-scale Grids

description: We investigate wind tunnel turbulence generated by both conventional and multi-scale grids. Measurements were made in a tunnel which has a large test-section, so that possible side wall effects are very small and the length assures that the turbulence has time to settle down to a homogeneous shear-free state. The conventional and multi-scale grids were all designed to produce turbulence with the same integral scale, so that a direct comparison could be made between the different flows. Our primary finding is that the behavior of the turbulence behind our multi-scale grids is virtually identical to that behind the equivalent conventional grid. In particular, all flows exhibit a power-law decay of energy, $u^2 \sim t^{-n}$, where $n$ is very close to the classical Saffman exponent of $n = 6/5$. Moreover, all spectra exhibit classical Kolmogorov scaling, with the spectra collapsing on the integral scales at small $k$, and on the Kolmogorov micro-scales at large $k$. Our results are at odds with some other experiments performed on similar multi-scale grids, where significantly higher energy decay exponents and turbulence levels have been reported.
