description: Federated Learning (FL) can be used in mobile edge networks to train machine learning models in a distributed manner. Recently, FL has been interpreted within a Model-Agnostic Meta-Learning (MAML) framework, which brings FL significant advantages in fast adaptation and convergence over heterogeneous datasets. However, existing research simply combines MAML and FL without explicitly addressing how much benefit MAML brings to FL and how to maximize such benefit over mobile edge networks. In this paper, we quantify the benefit from two aspects: optimizing FL hyperparameters (i.e., sampled data size and the number of communication rounds) and resource allocation (i.e., transmit power) in mobile edge networks. Specifically, we formulate the MAML-based FL design as an overall learning time minimization problem, under the constraints of model accuracy and energy consumption. Facilitated by the convergence analysis of MAML-based FL, we decompose the formulated problem and then solve it using analytical solutions and the coordinate descent method. With the obtained FL hyperparameters and resource allocation, we design a MAML-based FL algorithm, called Automated Federated Learning (AutoFL), that is able to conduct fast adaptation and convergence. Extensive experimental results verify that AutoFL outperforms other benchmark algorithms regarding the learning time and convergence performance.

description: The cross sections of elastic neutrino scattering on electrons and nuclei in the regime of low-energy transfer are known to be very sensitive to neutrino electromagnetic properties. In particular, the magnetic moment of the neutrino can be effectively searched using liquid or solid detectors with a very low energy threshold. We present the formalism that incorporates the neutrino magnetic moment contribution in the theoretical treatment of the low-energy elastic neutrino scattering on a condensed-matter target. The concept of the dynamic structure factor is employed to describe the collective effects in the target. The differential cross section for tritium antineutrino scattering on the superfluid $^4$He is calculated numerically. We find that the neutrino magnetic moment of the order of $10^{-11}μ_B$ strongly affects the cross section. Our results can be used in the search of neutrino magnetic moments in future low-energy neutrino scattering experiments with liquid or solid targets.

description: The pointwise space-time behaviors of the Green's function and the global solution to the modified Vlasov- Poisson-Boltzmann (mVPB) system in one-dimensional space are studied in this paper. It is shown that, the Green's function admits the diffusion wave, the Huygens's type sound wave, the singular kinetic wave and the remainder term decaying exponentially in space-time. These behaviors are similar to the Boltzmann equation (Liu and Yu in Comm. Pure Appl. Math. 57: 1543-1608, 2004). Furthermore, we establish the pointwise space-time nonlinear diffusive behaviors of the global solution to the nonlinear mVPB system in terms of the Green's function.

description: Isatin oxamohydrazide (L) reacted with the aqueous solution of silver nitrate at room temperature afforded the polymeric silver(I) nitrato complex, [Ag2L′(NO3)2]n, (1) of the azine ligand (L′). Similarly, the reaction of L with silver(I) perchlorate gave the [Ag2L′2(ClO4)2]n, (2) coordination polymer. Careful inspection of the crystals from the nitrato complex preparation showed the presence of another crystalline product which is found to be [Ag(Isatin-3-hydrazone)NO3], (3) suggesting that the reaction between silver(I) nitrate and L proceeds first by the hydrolysis of L to the isatin hydrazone which attacks another molecule of L to afford L′. Testing metal salts such as Ni2+, Co2+, Mn2+, Cu2+ and Cd2+ did not undergo any reaction with L either under the same reaction conditions or with heating under reflux up to 24 h. Treatment of the warm alcoholic solution of L with few drops of 1 : 1 (v/v) hydrochloric acid gave the free ligand (L′) in good yield. The [Ag2L′(NO3)2]n complex forms a two-dimensional infinite coordination polymer, while the [Ag2L′2(ClO4)2]n forms one-dimensional infinite chains with an alternating silver-azine backbone. Quantitative analysis of the intermolecular interactions in their crystals is made using Hirshfeld surface analysis. Density functional theory studies were performed to investigate the coordination bonding in the studied complexes.

description: Σκοπός της παρούσας εργασίας είναι να διαπιστωθεί εάν η Δραματική Τέχνη στην Εκπαίδευση μπορεί να επηρεάσει θετικά την ψυχική ανθεκτικότητα μαθητών με ηλικία 10 ετών. Η ψυχική ανθεκτικότητα αποτελεί μία δυναμική ικανότητα του ατόμου που το βοηθά να ανταπεξέρχεται στις δυσκολίες της ζωής, προκειμένου να χαρακτηρίζεται από συναισθηματική ευεξία. Με στόχο του να είσαι ψυχικά ανθεκτικός, χρειάζεται πλήθος γνωρισμάτων, όπως είναι η αυτοεκτίμηση, η κοινωνικότητα, το χιούμορ, η αυτοαποτελεσματικότητα και οι υγιείς διαπροσωπικές σχέσεις. Πρόκειται για κάποιους προστατευτικούς παράγοντες, οι οποίοι μάχονται τους παράγοντες κινδύνου, όπως είναι η παθολογία των γονέων, το στρες, οι γενετικές δυσκολίες ή οι φυσικές καταστροφές. Κατά τη βιβλιογραφική έρευνα, η Δραματική Τέχνη στην Εκπαίδευση προσφέρει ευκαιρίες στους μαθητές να καλλιεργήσουν την ψυχική ανθεκτικότητά τους, υιοθετώντας μηχανισμούς αντίστασης για τη διαχείριση των προβλημάτων τους. Άλλωστε, η Δραματική Τέχνη στην Εκπαίδευση αποτελεί εξορισμού μία παιδαγωγική προσέγγιση που προσφέρει ευκαιρίες για ελεύθερο παιχνίδι σε υποστηριζόμενο πλαίσιο, εφόσον συνδυάζεται με διάθεση για συνεργασία και αυτοσχεδιασμό. Με γνώμονα τα παραπάνω, ο ερευνητικός στόχος επιλέχθηκε να εξεταστεί από τη μικτή ερευνητική προσέγγιση για τη συλλογή ποιοτικών και ποσοτικών δεδομένων. Τα δεδομένα, που συλλέχθηκαν, ακολούθησαν τις παραμέτρους της έρευνας δράσης και του οιονεί πειραματικού σχεδίου και αναλύθηκαν κατά την σταθερή συγκριτική ανάλυση και την επαγωγική στατιστική αντιστοίχως. Το δείγμα της έρευνας περιλάμβανε 22 μαθητές Δημοτικού Σχολείου, εκ των οποίων 13 ανήκαν στην πειραματική ομάδα και 9 στην ομάδα ελέγχου. Στους μαθητές χορηγήθηκε το ερωτηματολόγιο The Resilience Scale (RS) των Wagnild & Young (1993), σε απλοποιημένη εκδοχή του από τους Neill & Dias (2001) και μεταφρασμένο στα ελληνικά από την Λεοντοπούλου (2010). Τα αποτελέσματα της ποσοτικής ανάλυσης δεν έδωσαν κάποια στατιστικά σημαντική διαφορά που να αποδεικνύει βελτίωση της ψυχικής ανθεκτικότητας των μαθητών. Αντιθέτως, η ανάλυση των ποιοτικών δεδομένων οδήγησε σε ενισχυμένη ανθεκτικότητα ως προς τις δεξιότητες της συμμετοχικότητας, της αυτοαποτελεσματικότητας και της ευρηματικότητας.

description: The chemical composition of stars hosting small exoplanets (with radii less than four Earth radii) appears to be more diverse than that of gas-giant hosts, which tend to be metal-rich. This implies that small, including Earth-size, planets may have readily formed at earlier epochs in the universe's history when metals were more scarce. We report Kepler spacecraft observations of Kepler-444, a metal-poor Sun-like star from the old population of the Galactic thick disk and the host to a compact system of five transiting planets with sizes between those of Mercury and Venus. We validate this system as a true five-planet system orbiting the target star and provide a detailed characterization of its planetary and orbital parameters based on an analysis of the transit photometry. Kepler-444 is the densest star with detected solar-like oscillations. We use asteroseismology to directly measure a precise age of 11.2 +/- 1.0Gyr for the host star, indicating that Kepler-444 formed when the universe was less than 20% of its current age and making it the oldest known system of terrestrial-size planets. We thus show that Earth-size planets have formed throughout most of the universe's 13.8 billion year history, leaving open the possibility for the existence of ancient life in the Galaxy. The age of Kepler-444 not only suggests that thick-disk stars were among the hosts to the first Galactic planets, but may also help to pinpoint the beginning of the era of planet formation.

description: We study properties of resonant solutions to the scalar wave equation in several axially symmetric spacetimes. We prove that non-axial resonant modes do not exist neither in the Lanczos dust cylinder, the $(2+1)$ extreme BTZ spacetime nor in a class of simple rotating wormhole solutions. Moreover, we find unstable solutions to the wave equation in the Lanczos dust cylinder and in the $r^2 <0$ region of the extreme $(2+1)$ BTZ spacetime, two solutions that possess closed timelike curves. Similarities with previous results obtained for the Kerr spacetime are explored.

description: Background: Heart rate variability (HRV) has become a regular metric for practitioners assessing the dose-response to exercise. The utility of smartphone applications capable of examining HRV using wearable technology has made this form of cardiac assessment more efficient and effective outside of laboratory settings. Purpose: This opinion piece will discuss the various forms of validity and reliability within research, and their applications towards establishing the accuracy and consistency of HRV smartphone applications. Conclusions: The unremitting creation of new HRV smartphone applications is cause for the continued examination of their validity and reliability. Understanding that the definition of validity has a broad meaning, requires researchers to state the exact form of validity they intend to examine. Furthermore, all forms of validity must be meticulously examined and viewed as equivalent when establishing the accuracy of a smartphone application. When assessing the reliability of an HRV application, researchers should focus on determining the consistency of its error in relation to the gold standard using repeated trials.

description: We report the first planet discovery from the two-wheeled Kepler (K2) mission: HIP 116454 b. The host star HIP 116454 is a bright (V = 10.1, K = 8.0) K1 dwarf with high proper motion and a parallax-based distance of 55.2 ± 5.4 pc. Based on high-resolution optical spectroscopy, we find that the host star is metal-poor with [Fe/H] = −0.16±0.08 and has a radius R = 0.716 ± 0.024 R and mass M = 0.775±0.027 M. The star was observed by the Kepler spacecraft during its Two-Wheeled Concept Engineering Test in 2014 February. During the 9 days of observations, K2 observed a single transit event. Using a new K2 photometric analysis technique, we are able to correct small telescope drifts and recover the observed transit at high confidence, corresponding to a planetary radius of Rp = 2.53 ± 0.18 R⊕. Radial velocity observations with the HARPS-N spectrograph reveal a 11.82 ± 1.33 M⊕ planet in a 9.1 day orbit, consistent with the transit depth, duration, and ephemeris. Follow-up photometric measurements from the MOST satellite confirm the transit observed in the K2 photometry and provide a refined ephemeris, making HIP 116454 b amenable for future follow-up observations of this latest addition to the growing population of transiting super-Earths around nearby, bright stars.

description: Laser cooling of translational motion of small molecules is performed by addressing transitions that ensure spontaneous emission cannot cause net rotational excitation. This will not be possible once the rotational splitting becomes comparable to the operational excitation linewidth, as will occur for large molecules or wide bandwidth lasers. We show theoretically that in this regime, angular momentum transfer from red-detuned Doppler cooling light can also exert a damping torque on linear molecules, cooling rotation to the same Doppler limit (typically $\approx$ 500 $μ$K for molecules with $\approx$ 10 ns excited-state lifetimes). This cooling process is derived from photon spin, and indicates that standard optical molasses can also cool molecular rotation with no additional experimental resources.

description: We present an updated analysis of LHS 6343, a triple system in the Kepler field which consists of a brown dwarf eclipsing one member of a widely-separated M+M binary system. By analyzing the full Kepler dataset and 34 Keck/HIRES radial velocity observations, we measure both the observed eclipse depth and Doppler semiamplitude to 0.5% precision. With Robo-AO and Palomar/PHARO adaptive optics imaging as well as TripleSpec spectroscopy, we measure a model-dependent mass for LHS 6343 C of 62.1 +/- 1.2 M_Jup and a radius of 0.783 +/- 0.011 R_Jup. We detect the secondary eclipse in the Kepler data at 3.5 sigma, measuring e cos omega = 0.0228 +/- 0.0008. We also derive a method to measure the mass and radius of a star and transiting/eclipsing companion directly, without any reliance on stellar models. The mass and radius of both objects depend only on the orbital period, stellar density, reduced semimajor axis, Doppler semiamplitude, eccentricity, and inclination. With this method, we calculate a model-independent mass and radius for LHS 6343 C to a precision of 3% and 2%, respectively.

description: Background: Female undergraduate students often speak to the stress associated with their university experience. Stressors can lead to an elevated cortisol awakening response, but chronic fatigue and burnout have conversely been associated with a blunted cortisol awakening response. The impact of chronic student-life stress on the cortisol awakening response is currently understudied, and therefore more research is warranted. Purpose: The primary purpose of this study was to observe self-reported stress levels over the academic year and determine the impact of student-life stress on the cortisol awakening response of female undergraduate students, while controlling for the day of the menstrual cycle. A secondary purpose was to determine the relationship between self-reported exercise levels and the cortisol awakening response in this student sample, via a post-hoc analysis. Methods: As part of this feasibility study, stress and the cortisol awakening response were measured on day-21 of each menstrual cycle over the 2018-19 academic year in 19 female undergraduate students, who self-reported their exercise habits by completing the Godin Leisure Time Exercise Questionnaire. Results: Stress and the cortisol awakening response displayed no significant relationship (p=0.398) or change over time (p=0.419) in the academic year, however a trend toward low/blunted cortisol awakening response was observed, suggesting a possible impact of burnout in this population. Exercise levels had a positive significant relationship with the cortisol awakening response (p=0.002). Conclusions: Further research is warranted to verify whether a blunted cortisol awakening response or student burnout exists, and if increased exercise levels lead to higher, healthier cortisol awakening response levels in this population.

description: We study the relationships between galaxy environments and galaxy properties related to disk (re)growth, considering two highly complete samples that are approximately baryonic mass limited into the high-mass dwarf galaxy regime, the Environmental COntext (ECO) catalog (data release herein) and the B-semester region of the REsolved Spectroscopy Of a Local VolumE (RESOLVE) survey. We quantify galaxy environments using both group identification and smoothed galaxy density field methods. We use by-eye and quantitative morphological classifications plus atomic gas content measurements and estimates. We find that blue early-type (E/S0) galaxies, gas-dominated galaxies, and UV-bright disk host galaxies all become distinctly more common below group halo mass ~10^11.5 Msun, implying that this low group halo mass regime may be a preferred regime for significant disk growth activity. We also find that blue early-type and blue late-type galaxies inhabit environments of similar group halo mass at fixed baryonic mass, consistent with a scenario in which blue early types can regrow late-type disks. In fact, we find that the only significant difference in the typical group halo mass inhabited by different galaxy classes is for satellite galaxies with different colors, where at fixed baryonic mass red early and late types have higher typical group halo masses than blue early and late types. More generally, we argue that the traditional morphology-environment relation (i.e., that denser environments tend to have more early types) can be largely attributed to the morphology-galaxy mass relation for centrals and the color-environment relation for satellites.

description: In the past decade, several conceptual papers have linked variation in animal personality to variation in cognition, and recent years have seen a flood of empirical studies testing this link. However, these results have not been synthesized in a quantitative way. Here, we systematically search the literature and conduct a phylogenetically controlled meta-analysis of empirical papers that have tested the relationship between animal personality (exploration, boldness, activity, aggression and sociability) and cognition (initial learning/reversal speed, number of correct choices/errors after standard training). We find evidence for a small but significant relationship between variation in personality and variation in learning across species in the absolute scale; however, the direction of this relationship is highly variable and when both positive and negative effect sizes are considered, the average effect size does not differ significantly from zero. Importantly, this variation between studies is not explained by differences in personality or learning measure, or taxonomic grouping. Further, these results do not support current hypotheses suggesting that that fast-explorers are fast-learners or that slow-explorers perform better on tests of reversal learning. Rather, we find evidence that bold animals are faster learners, but only when boldness is measured in response to a predator (or simulated predator) and not when boldness is measured by exposure to a novel object (or novel food). Further, although only a small sub-sample of papers reported results separately for males and females, sex explained a significant amount of variation in effect size. These results, therefore, suggest that, while personality and learning are indeed related across a range of species, the direction of this relationship is highly variable. Thus further empirical work is needed to determine whether there are important moderators of this relationship.This article is part of the theme issue ‘Causes and consequences of individual differences in cognitive ability’.

description: In the past decade, several conceptual papers have linked variation in animal personality to variation in cognition, and recent years have seen a flood of empirical studies testing this question. However, these results have not been synthesized in a quantitative way. Here, we systematically search the literature and conduct a phylogenetically controlled meta-analysis of empirical papers that have tested the relationship between animal personality (exploration, boldness, activity, aggression and sociability) and cognition (initial learning/reversal speed, number of correct choices/errors after standard training). We find evidence for a small but significant relationship between variation in personality and variation in learning across species in the absolute scale, however the direction of this relationship is highly variable and when both positive and negative effect sizes are considered the average effect size does not differ significantly from zero. Importantly, this variation between studies is not explained by differences in personality or learning measure, or taxonomic grouping. Further, these results do not support current hypotheses suggesting that that fast-explorers are fast-learners or that slow-explorers perform better on tests of reversal learning. Rather, we find evidence that bold animals are faster learners, but only when boldness is measured in response to a predator (or simulated) and not when boldness is measured by exposure to a novel object (or novel food). Further, although only a small sub-sample of papers reported results separately for males and females, sex explained a significant amount of variation in effect size. These results, therefore, suggest that, while personality and learning are indeed related across a range of species, the direction of this relationship is highly variable. Thus further empirical work is needed to determine whether there are important moderators of this relationship.This article is part of the theme issue ‘Causes and consequences of individual differences in cognitive ability’.

description: We study thermal radiation from nonlinear ($χ^{(3)}$) photonic cavities coupled to external channels and subject to incident monochromatic light. Our work extends related work on nonlinear mechanical oscillators [Phys. Rev. Lett. 97, 110602 (2006)] to the problem of thermal radiation, demonstrating that bistability can enhance thermal radiation by orders of magnitude and result in strong lineshape alternations, including "super-narrow spectral peaks" occurring at the onset of kinetic phase transitions. We show that when the cavities are designed so as to have perfect linear absorptivity (rate matching), such thermally activated transitions can be exploited to dramatically tune the output power and radiative properties of the cavity, leading to a kind of Kerr-mediated thermo-optic effect. Finally, we demonstrate that in certain parameter regimes, the output radiation exhibits Stokes and anti-Stokes side peaks whose relative magnitudes can be altered by tuning the internal temperature of the cavity relative to its surroundings, a consequence of strong correlations and interference between the emitted and reflected radiation.

description: Only 25% of children and youth aged 10-17 are meeting the national guidelines for physical activity (PA) in Canada. COVID-19 pandemic regulations have additionally reduced the engagement of children and youth with leisure time PA. Purpose: The purpose of this study was to investigate motivations for leisure time PA of children and youth during the COVID-19 pandemic utilizing organismic integration theory (OIT). Methods: Participants were children and youth aged 11-14 years, living in Canada at the time of questionnaire completion. Motivations and regulations were assessed online using the Behavioural Regulations in Exercise Questionnaire version 3, and PA was assessed using the Godin Leisure Time Exercise Questionnaire. Results: Higher levels of PA intensity were correlated with more autonomous forms of regulations and motivation, whereas lower levels of PA intensity were not significantly correlated with more controlled forms of motivation. Greater scores of the relative autonomy index predicted higher levels of PA intensity. Sex moderated the relationship between integrated regulation and PA, explaining 7-8% of the variance. Conclusions: Sex was the key predictor of PA outcomes, indicating other variables beyond regulations should be further explored regarding children and youth’s motivations for leisure time PA, in the context of the COVID-19 pandemic.

description: As an artist, I interrupt spaces with installations that invite community members to make zines or letterpress print together, to act out dialogues or to eat hot pot. I could frame all the artworks of my period of study at Emily Carr as attempts to define this tendency: discovering self and agency by embedding myself holistically in my community. Share My Lunch is an example of a series of community events that cater to the interpersonal connection often taken for granted by social superstructures. BACKTALK is a curatorial project behind which hours of collaboration took place to thoughtfully represent the voices of individuals in a collective call out of institutional racism. The Centre for Polite Dissent is both a physical and imaginary space where those who do not inhabit a norm (or don’t quite inhabit a norm) can be praised for their acts of denial as diversity work. Creating these spaces means understanding their separation from the bureaucratic work of altering infrastructure. These projects can ignore institutional oversight and methods of sustainability while presenting physical and conceptual interruptions for deeper connection, community strength and refusals of silence. But their realistic inefficacy doesn’t belittle their power. I use theory-driven social frameworks to imagine new possible worlds free from restrictions, walls, and hierarchies that limit the creation of necessary support structures. I propose that an art practice can flourish in the middle ground between imagining new realities and instigating institutional change. Framed by the inner workings of personal relationships and social experiences, this thesis support document showcases different projects that attempt to tread this middle ground by carving out community spaces that prioritize connection and solidarity.

description: Depleted Monolithic Active Pixel Sensor (DMAPS) sensors developed in the Tower Semiconductor 180 nm CMOS imaging process have been designed in the context of the ATLAS ITk upgrade Phase-II at the HL-LHC and for future collider experiments. The ``MALTA-Czochralski (MALTA-Cz)'' full size DMAPS sensor has been developed with the goal to demonstrate a radiation hard, thin CMOS sensor with high granularity, high hit-rate capability, fast response time and superior radiation tolerance. The small pixel size ($36.4\times 36.4$~$\mu$m$^2$) provides high spatial resolution. Its asynchronous readout architecture is designed for high hit-rates and fast time response in triggered and trigger-less detector applications. The readout architecture is designed to stream all hit data to the multi-channel output which allows an off-sensor trigger formation and the use of hit-time information for event tagging. The sensor manufacturing has been optimised through process adaptation and special implant designs to allow the manufacturing of small electrode DMAPS on thick high-resistivity p-type Czochralski substrate. The special processing ensures excellent charge collection and charge particle detection efficiency even after a high level of radiation. Furthermore the special implant design and use of a Czochralski substrate improves the sensor's time resolution. This paper presents a summary of sensor design optimisation through process and implant choices and TCAD simulation to model the signal response. Beam and laboratory test results on unirradiated and irradiated sensors have shown excellent detection efficiency after a dose of $2\times10^{15}$ 1 MeV n$_{eq}$/cm$^{2}$. The time resolution of the sensor is measured to be $\sigma=2$~ns.

description: The spherical Sherrington-Kirkpatrick model is a spherical mean field model for spin glass. We consider the fluctuations of the free energy at arbitrary non-critical temperature for the 2-spin model with no magnetic field. We show that in the high temperature regime the law of the fluctuations converges to the Gaussian distribution just like in the Sherrington-Kirtkpatrick model. We show, on the other hand, that the law of the fluctuations is given by the GOE Tracy-Widom distribution in the low temperature regime. The orders of the fluctuations are markedly different in these two regimes. A universality of the limit law is also proved.

description: There is direct and indirect evidence that cold dust ( T< 100 K) may be present in the outflow of some starburst galaxies. However, the geometry, energy and mass of this dusty superwind is virtually unknown in the far-infrared wavelengths (70--500 μm). In particular there are crucial questions regarding these super-winds: what are the physical conditions under which the gas and dust finds itself? what is the extent of the dust and gas and the importance for its survival? what is the nature of the turbulence boundary arising from the wind interaction? We present a detail analysis and comparison of very deep far-infrared observations of two nearby Starburst galaxies, NGC 3079 and NGC 4631. We compare the dust distribution between our Herschel images, Spitzer IRAC 4.5 and 8 μm and, MIPS 24 μm. We examine the dust physical properties in the wind and halo of these galaxies.
