description: Recent technological advances have witnessed the rapid encroachment of computing systems into our social spaces. Their acceptance in these social spaces by other occupants, however, might be mostly contingent on their social appropriateness. Notions of social appropriateness might seem vague but even people who don’t act on this commonsense knowledge, and accord to social norms, can sometimes find themselves ostracized from society. It is reflected in behavior that supports a sense of successful engagement and connection. Such behavior communicates a desire to be accepted and a willingness to engage, as opposed to inappropriateness that conveys indifference, rejection or even danger. As social actors, how can systems improve their interactions with us in order to better succeed at their tasks? Perhaps, more interestingly, how might they even improve our communications with each other? In this thesis we describe a framework to identify opportunities to design systems that can begin to act appropriately in social settings, which we call Considerate Systems. It includes a design process and guidelines, which allows an interaction to be viewed from the perspectives of the user, system and task. It also includes an architecture that guides the addition of productive social responses to interactive systems. We demonstrate the utility of this framework by exploring two types of scenarios that impact social interactions in contrasting ways. Remote interactions (such as on a conference call) suffer from an impinging of social cues that people rely on while communicating. On the other hand, situated multitasking interactions (such as texting while driving) can easily overwhelm users and detract from their performance. The framework is applied towards the design of autonomous agents tackling problems endemic to such scenarios. We evaluate their success with respect to specific scenario goals. We conclude by noting that while the challenges of instilling computing systems with a sense of appropriateness seem daunting, our productive use of systems can be enhanced with them.

description: The seven approximately Earth-sized transiting planets in the \object{TRAPPIST-1} system provide a unique opportunity to explore habitable zone and non-habitable zone small planets within the same system. Its habitable zone exoplanets -- due to their favorable transit depths -- are also worlds for which atmospheric transmission spectroscopy is within reach with the Hubble Space Telescope (HST) and with the James Webb Space Telescope (JWST). We present here an independent reduction and analysis of two \textit{HST} Wide Field Camera 3 (WFC3) near-infrared transit spectroscopy datasets for six planets (b through g). Utilizing our physically-motivated detector charge trap correction and a custom cosmic ray correction routine, we confirm the general shape of the transmission spectra presented by \textbf{\citet{deWit2016, deWit2018}}. Our data reduction approach leads to a 25\% increase in the usable data and reduces the risk of confusing astrophysical brightness variations (e.g., flares) with instrumental systematics. No prominent absorption features are detected in any individual planet's transmission spectra; by contrast, the combined spectrum of the planets shows a suggestive decrease around 1.4\,$\micron$ similar to an inverted water absorption feature. Including transit depths from \textit{K2}, the SPECULOOS-South Observatory, and \textit{Spitzer}, we find that the complete transmission spectrum is fully consistent with stellar contamination owing to the transit light source effect. These spectra demonstrate how stellar contamination can overwhelm planetary absorption features in low-resolution exoplanet transit spectra obtained by \textit{HST} and \textit{JWST} and also highlight the challenges in combining multi epoch observations for planets around rapidly rotating spotted stars.

Determination of pseudo-Goldstone boson-photon coupling by the differential time delay of pulsar signals

description: Pseudo-Goldstone bosons couple with photons through a P and T violating interaction of the form ${\cal {L_I}}=g_{aγγ}~ a F\tilde F$. Strong magnetic fields in rotating compact stars induce a non-zero ${\vec E}\cdot{\vec B}$ outside the stellar surface which acts as a source for the pseudo-scalar field. Pulsar signals propagating through this pseudo-scalar `hair' suffer a differential time lag between the left and the right circularly polarised modes because of the P and T violating pseudoscalar boson-photon interaction. Determination of this time lag upto a microsecond accuracy can lead to a measurment of (or rule out) pseudo-Goldstone boson-photon coupling upto $g_{a γγ}\leq 4.6 \times 10^{-9}~GeV^{-1}$.

description: Hubble Space Telescope archive data are used to perform photometry of stars in seven fields at the center and periphery of the galaxy NGC2366. The variation of the number density of stars of various ages with galactocentric radius and along the minor axis of the galaxy are determined. The boundaries of the thin and thick disks of the galaxy are found. The inferred sizes of the subsystems of NGC2366 ($Z_{thin} = 4$ kpc and $Z_{thick} = 8$ kpc for the thin and thick disks, respectively) are more typical for spiral galaxies. Evidence for a stellar halo is found at the periphery of NGC2366 beyond the thick disk of the galaxy.

description: Der Birkensee liegt im Norden des Schönbuchs, und zwar in einem Plateaumoor auf dem Bromberg, zwischen Schaichhof und Goldersbachtal, auf vergleytem Boden. Das Moor, das sich an ihn anschließt, ist durch Missenbildung entstanden, sei es durch Waldweide oder durch Überhege in den Zeiten der jagdbegeisterten württembergischen Herzöge. Es hat ombrophilen Charakter. Ihren Namen verdanken See und Moor dem Umstand, daß die Moorbirke, Betula pubescens Ehrhart, in großer Zahl vorkommt und der Landschaft ein schwermütiges Gepräge gibt. Der Wanderer ist überrascht, außerhalb des Schwarzwaldes eine versumpfte Stelle auf einem Höhenrücken anzutreffen, wie er sie nur dem sauren Buntsandsteinboden in einem Gebiet mit hoher Niederschlagsmenge zugetraut hatte. Seit Beginn der Untersuchungen (1979/80) wurden pflegerische Maßnahmen durchgeführt. Der Seeboden wurde vertieft, da der Naturschutz der Verlandung entgegenwirken wollte. Doch brachte das nicht nur Vorteile. Pflanzen, die auf periodisch trockenfallenden Grund angewiesen sind, lassen sich heute schwerer beobachten als früher. Das Moor wurde – wohl zum Zweck der Besucherlenkung – durch einen Pfad erschlossen, dadurch aber eben auch zerschnitten. Der See lag schon lange am Rand des Moors. Heute ist er von diesem durch eine trockene Zone am Ufer getrennt. Das Moor wird nicht mehr im gleichen Maße wie einst bei hohem Wasserstand vom überfließenden Naß zusätzlich berieselt. In dieser Arbeit soll daher unter anderem auch der frühere Zustand dokumentiert werden.

description: Event detection rates for WIMP-nucleus interactions are calculated for $^{71}$Ga, $^{73}$Ge, $^{75}$As and $^{127}$I (direct dark matter detectors). The nuclear structure form factors, that are rather independent of the underlying beyond the Standard Model particle physics scenario assumed, are evaluated within the context of the deformed nuclear shell model (DSM) based on Hartree-Fock nuclear states. Along with the previously published DSM results for $^{73}$Ge, the neutrino-floor due to coherent elastic neutrino-nucleus scattering (CE$ν$NS), an important source of background to dark matter searches, is extensively calculated. The impact of new contributions to CE$ν$NS due to neutrino magnetic moments and $Z^\prime$ mediators at direct dark matter detection experiments is also examined and discussed. The results show that the neutrino-floor constitutes a crucial source of background events for multi-ton scale detectors with sub-keV capabilities.

description: We report on spin dynamics of individual, localized neutral impurities immersed in a Bose-Einstein condensate. Single Cesium atoms are transported into a cloud of Rubidium atoms, thermalize with the bath, and the ensuing spin-exchange between localized impurities with quasi-spin $F_i=3$ and bath atoms with $F_b=1$ is resolved. Comparing our data to numerical simulations of spin dynamics we find that, for gas densities in the BEC regime, the dynamics is dominated by the condensed fraction of the cloud. We spatially resolve the density overlap of impurities and gas by the spin-population of impurities. Finally we trace the coherence of impurities prepared in a coherent superposition of internal states when coupled to a gas of different densities. For our choice of states we show that, despite high bath densities and thus fast thermalization rates, the impurity coherence is not affected by the bath, realizing a regime of sympathetic cooling while maintaining internal state coherence. Our work paves the way toward non-destructive probing of quantum many-body systems via localized impurities.

description: In the context of hermitean one--matrix models we show that the emergence of the NLS hierarchy and of its reduction, the KdV hierarchy, is an exact result of the lattice characterizing the matrix model. Said otherwise, we are not obliged to take a continuum limit to find these hierarchies. We interpret this result as an indication of the topological nature of them. We discuss the topological field theories associated with both and discuss the connection with topological field theories coupled to topological gravity already studied in the literature.

Pavao Skalić protiv Pier Paola Vergerija

Subjects: reformation

description: The paper reconstructs the chronology and gathers testimonials about the quarrel between two exules Christi (“exiles for Christ’s sake”) who came to reformation Germany from the Roman Catholic South: Pier Paolo Vergerio from Koper and Paul Skalić (1534-1575) from Zagreb. The young Skalić, former Vienna Hofkaplan who broke with papacy in 1555-1557, was a newcomer, of much less propagandistic value in comparison with thirty six years older Vergerio, bishop of Koper and papal nunzio, with almost a decade longer reformation activity (from 1548). Both, however, had to compete for influence and favour of German reformist magnates, especially Christoph, Duke of Württemberg, and Albrecht, Duke of Prussia. Skalić tried to strengthen his position by making fantastic, although impressively documented and argued (and, at that time, hard to verify) claims to be descended from the della Scala, medieval rulers of Verona. When others, Vergerio among them, tried to refute his claims, Skalić retaliated aggressively, in July 1560 circulating a pamphlet on his adversaries. In January 1561, a commission appointed by the Duke Christoph brokered a reconciliation between Skalić and Vergerio, but, when Skalić by the end of 1561 went to Königsberg and started a dazzling carreer at the court of the Prussian Duke Albrecht, another champion of reformation, Vergerio tried to counter that by spreading warnings about Skalić’s unfounded aspirations to nobility; also, Vergerio’s nephews were employed by the Duke Albrecht as diplomats, so Skalić was competing with Vergerio’s family in Prussia as well. In 1563, Skalić published a book of Satirae philosophicae, including in it the pamphlet against Vergerio from 1560. This text, De statu huius mundi, is a set of 22 dramatic dialogues “in the style of Terence”, with characters named Aristippus, Democritus, Empedocles, Euphorbus, Mastinus, Facinus, Brunorus etc. The main character is the vile, greedy, dissolute Aristippus (with the same goals in life as the Greek philosopher from Cyrene), who has committed an immense number of wrongdoings and crimes. In winter of 1563, Vergerio presented an official complaint before the Duke of Prussia and the University of Königsberg, but did not achieve anything; Skalić’s influence with the Duke was too strong, and the fantastic adventurer from Zagreb will be removed from power in Prussia only by the intervention of the King of Poland in 1566. We present the contents of Skalić’s satyrical dialogues De statu huius mundi, recognize their literary origin not only in Terence, but even more in Lucian’s Dialogues of the Dead, and suggest that they are connected with the tradition of German Reformationsdialog as polemical vehicle (which has been adopted during 1550’s by Vergerio as well in his attacks on the papacy).

description: In this work the significance of two of the most important Sabine deities, Vacuna and Sabus, is investigated. To this aim. the origin of Sabines is investigated and their relationships with other ancient Italic peoples are analysed. In particular, Proto-Hiberians, Proto-Umbrians, Proto-Etruscans, Proto-Gaul-Latins, and Pelasgians are considered together with their migrations to Italy. The peopling of ancient Central Italy is then reconstructed taking the ancient sources and the most recent theories into account. In such a context, the origin, the developing, and the significance of God Sabus and Godess Vacuna is analysed seeking similarities and identifications with the deities of the other ancient Italic peoples.

description: Green's function Monte Carlo calculations of magnetic dipole, electric quadrupole, Fermi, and Gamow-Teller transition matrix elements are reported for A=6,7 nuclei. The matrix elements are extrapolated from mixed estimates that bracket the relevant electroweak operator between variational Monte Carlo and GFMC propagated wave functions. Because they are off-diagonal terms, two mixed estimates are required for each transition, with a VMC initial (final) state paired with a GFMC final (initial) state. The realistic Argonne v18 two-nucleon and Illinois-2 three-nucleon interactions are used to generate the nuclear states. In most cases we find good agreement with experimental data.

description: We propose the idea of "Earth Shielding" to reject cosmic-ray backgrounds, in the search for boosted dark matter at surface neutrino detectors, resulting in the enhancement of the signal-to-background ratio. The identification of cosmic-originating rare signals, especially lacking features, at surface detectors is often considered hopeless due to a vast amount of cosmic-ray-induced background, hence underground experiments are better motivated to avoid such a challenge. We claim that surface detectors can attain remarkable sensitivities to even featureless signals, once restricting to events coming through the Earth from the opposite side of the detector location for the signals leaving appreciable tracks from which the source direction is inferred. By doing so, potential backgrounds in the signal region of interest can be substantially suppressed. To validate our claim, we study experimental reaches at several surface experiments such as SBN Program (MicroBooNE, ICARUS, and SBND) and ProtoDUNE for elastic boosted dark matter signatures stemming from the Galactic Center. We provide a systematic discussion on maximizing associated signal sensitivities.

Critical Analysis of Baryon Masses and Sigma-Terms in Heavy Baryon Chiral Perturbation Theory

description: We present an analysis of the octet baryon masses and the $πN$ and $KN$ $σ$--terms in the framework of heavy baryon chiral perturbation theory. At next-to-leading order, ${\cal O}(q^3)$, knowledge of the baryon masses and $σ_{πN}(0)$ allows to determine the three corresponding finite low--energy constants and to predict the the two $KN$ $σ$--terms $σ^{(1,2)}_{KN} (0)$. We also include the spin-3/2 decuplet in the effective theory. The presence of the non--vanishing energy scale due to the octet--decuplet splitting shifts the average octet baryon mass by an infinite amount and leads to infinite renormalizations of the low--energy constants. The first observable effect of the decuplet intermediate states to the baryon masses starts out at order $q^4$. We argue that it is not sufficient to retain only these but no other higher order terms to achieve a consistent description of the three--flavor scalar sector of baryon CHPT. In addition, we critically discuss an SU(2) result which allows to explain the large shift of $σ_{πN}(2M_π^2) - σ_{πN}(0)$ via intermediate $Δ(1232)$ states.

description: Geologic carbon storage (GCS) is a crucial part of a proposed mitigation strategy to reduce the anthropogenic CO2 emissions to the atmosphere. During this process, CO2 is injected as super critical carbon dioxide (SC-CO2) in confined deep subsurface storage units, such as saline aquifers and depleted oil reservoirs. The deposition of vast amounts of CO2 in subsurface geologic formations may ultimately lead to CO2 leakage into overlying freshwater aquifers. Introduction of CO2 into these subsurface environments will greatly increase the CO2 concentration and will create CO2 concentration gradients that drive changes in the microbial communities present. While it is expected that altered microbial communities will impact the biogeochemistry of the subsurface, there is no information available on how CO2 gradients will impact these communities. The overarching goal of this dissertation is to understand how CO2 exposure will impact subsurface microbial communities at temperature and pressure that are relevant to GCS and CO2 leakage scenarios. To meet this goal, unfiltered, aqueous samples from a deep saline aquifer, a depleted oil reservoir, and a fresh water aquifer were exposed to varied concentrations of CO2 at reservoir pressure and temperature. The microbial ecology of the samples was examined using molecular, DNA-based techniques. The results from these studies were also compared across the sites to determine any existing trends. Results reveal that increasing CO2 leads to decreased DNA concentrations regardless of the site, suggesting that microbial processes will be significantly hindered or absent nearest the CO2 injection/leakage plume where CO2 concentrations are highest. At CO2 exposures expected downgradient from the CO2 plume, selected microorganisms emerged as dominant in the CO2 exposed conditions. Results suggest that the altered microbial community was site specific and highly dependent on pH. The site-dependent results suggests no ability to predict the emerging dominant species for other CO2exposed environments. This body of work improves the understanding of how a subsurface microbial community may respond to conditions expected from geologic carbon storage and CO2 leakage. This is the first step for understanding how a CO2 altered microbial community may impact injectivity, permanence of stored CO2, and subsurface water quality. .

description: New decay channels for the neutron into dark matter plus other particles have been suggested for explaining a long-standing discrepancy between the neutron lifetime measured from trapped neutrons versus those decaying in flight. Many such scenarios are already ruled out by their effects on neutron stars, and the decay into dark matter plus photon has been experimentally excluded. Here we explore the decay into a dark Dirac fermion $χ$ and a dark photon $A'$, which can be consistent with all constraints if $χ$ is a subdominant component of the dark matter. Neutron star constraints are evaded if the dark photon mass to coupling ratio is $m_{A'}/g' \lesssim (45-60)\,$MeV, depending upon the nuclear equation of state. $g'$ and the kinetic mixing between U(1)$'$ and electromagnetism are tightly constrained by direct and indirect dark matter detection, supernova constraints, and cosmological limits.

description: Thus far in the search for, and classification of, `physical' modular invariant partition functions $\sum N_{LR}\,\c_L\,\C_R$ the attention has been focused on the {\it symmetric} case where the holomorphic and anti-holomorphic sectors, and hence the characters $\c_L$ and $\c_R$, are associated with the same Kac-Moody algebras $\g_L=\g_R$ and levels $k_L=k_R$. In this paper we consider the more general possibility where $(\g_L,k_L)$ may not equal $(\g_R,k_R)$. We discuss which choices of algebras and levels may correspond to well-defined conformal field theories, we find the `smallest' such {\it heterotic} (\ie asymmetric) partition functions, and we give a method, generalizing the Roberts-Terao-Warner lattice method, for explicitly constructing many other modular invariants. We conclude the paper by proving that this new lattice method will succeed in generating all the heterotic partition functions, for all choices of algebras and levels.

description: We calculate the collisional energy loss of a muon of high energy $E$ in a hot QED plasma beyond logarithmic accuracy, i.e., we determine the constant terms of order O(1) in $-dE/dx \propto \ln{E}+ O(1)$. Considering first the $t$-channel contribution to $-dE/dx$, we show that the terms $\sim O(1)$ are sensitive to the full kinematic region for the momentum exchange $q$ in elastic scattering, including large values $q \sim O(E)$. We thus redress a previous calculation by Braaten and Thoma, which assumed $q << E$ and could not find the correct constant (in the large $E$ limit). The relevance of 'very hard' momentum transfers then requires, for consistency, that $s$ and $u$-channel contributions from Compton scattering must be included, bringing a second modification to the Braaten-Thoma result. Most importantly, Compton scattering yields an additional large logarithm in $-dE/dx$. Our results might have implications in the QCD case of parton collisional energy loss in a quark gluon plasma.

description: War dereinst der Südwesten Deutschlands der Garten von Eden, das Paradies auf Erden? Gewiß ein naheliegender Gedanke; denn hier lebten vor langen, langen Zeiten, umgeben von einem mannigfachen pflanzlichen und vielgestaltigen tierischen Leben, in einem ausgeglichenen, warm-gemäßigten Klima frühe Menschen: ein kraftvoller Adam samt einer Eva von kleinem Wuchs! Doch zwischen beiden klaffte eine zeitliche Lücke, ein Hiatus von gut einer viertel Million Jahren, und so wird die paradiesische Zweisamkeit allenfalls zu einem Gleichnis.

description: The exact superconducting phase of K2-xFe4+ySe5 has yet conclusively decided since its discovery due to its intrinsic multiphase in early material. In an attempt to resolve the mystery, we have carried out systematic structural studies on a set of well controlled samples with exact chemical stoichiometry K2-xFe4+xSe5 (x=0~0.3) that are heat-treated at different temperatures. Our investigations, besides the determination of superconducting transition, focus on the detailed temperature evolution of the crystalline phases using high resolution synchrotron radiation X-ray diffraction. Our results show that superconductivity appears only in those samples been treated at high enough temperature and then quenched to room temperature. The volume fraction of superconducting transition strongly depends on the annealing temperature used. The most striking result is the observation of a clear contrast in crystalline phase between the non-superconducting parent compound K2Fe4Se5 and the superconducting K2-xFe4+ySe5 samples. The x-ray diffraction patterned can be well indexed to the phase with I4/m symmetry in all temperature investigated. However, we need two phases with similar I4/m symmetry but different parameters to best fit the data at temperature below the Fe-vacancy order temperature. The results strongly suggest that superconductivity in K2-xFe4+ySe5 critically depends on the occupation of Fe atoms on the originally empty 4d site.

description: Objective To quantify clinical and cost long-term outcomes in cardiovascular stable post-myocardial-infarction patients. Research design and methods Subjects with a history of myocardial infarction (MI) who were 50–64 years old and MI- and stroke-free for ≥12 months (index date) were identified in a large US claims database. Individuals were followed for up to 5 years (mean: 2.0 years) after their index date. Main outcome measures Rates of MI, stroke, all-cause death, and a composite of these were analyzed via Cox regression models, adjusted for covariates. Results are reported for the overall population and the subgroups of those with type 2 diabetes, additional prior MI, and non-end-stage renal disease. As a secondary endpoint healthcare costs were evaluated at baseline and during each year of follow-up. Results Over the follow-up period, which averaged 2 years, 7.6% of all 13,492 subjects (10.5% vs. 5.4% with and without the selected risk factors, respectively) experienced at least one of the outcome events. The cumulative incidence rates over the entire follow-up period for the primary composite outcome were 20.8% and 12.2% for those with and without the selected atherothrombotic risk factors, respectively. The cardiovascular-related per-person-per-year healthcare costs during follow-up were higher in those with ≥1 additional risk factor compared to those without: $15,247 versus $7521. Costs were elevated over baseline costs throughout follow-up. Limitations Administrative claims data lack clinical detail. Generalizability of results is limited to the US commercially insured population of a similar age to that included in this study. Conclusions High risk MI survivors who have been event free for ≥1 year remained at substantial risk of CV events and had increased healthcare costs for up to 5 years post-MI. These long-term risks have not been previously demonstrated in a working-age US population and suggest an unmet need for continuing secondary prevention long-term post-MI.

Das Erinnern an dieses, den ländlichen Alltag jäh unterbrechende säkulare Begebnis wurde trotz des Verlustes der Belege über all die verflossenen Jahrhunderte hinweg bewahrt – unbeschadet des sich im ausgehenden 17. Jahrhundert anbahnenden Erkennens der wahren Natur derartiger fehlgedeuteter Bodenfunde als Lebensreste, als Zeugen vorzeitlichen Lebens und Sterbens, als die Stammesgeschichte erhellende Urkunden von hohem Wert.

WZW Commutants, Lattices, and Level 1 Partition Functions

description: A natural first step in the classification of all `physical' modular invariant partition functions $\sum N_{LR}\,\c_L\,\C_R$ lies in understanding the commutant of the modular matrices $S$ and $T$. We begin this paper extending the work of Bauer and Itzykson on the commutant from the $SU(N)$ case they consider to the case where the underlying algebra is any semi-simple Lie algebra (and the levels are arbitrary). We then use this analysis to show that the partition functions associated with even self-dual lattices span the commutant. This proves that the lattice method due to Roberts and Terao, and Warner, will succeed in generating all partition functions. We then make some general remarks concerning certain properties of the coefficient matrices $N_{LR}$, and use those to explicitly find all level 1 partition functions corresponding to the algebras $B_n$, $C_n$, $D_n$, and the 5 exceptionals. Previously, only those associated to $A_n$ seemed to be generally known.

description: We evaluate the cross section for anti-p p -> l+ l- pi0 in the forward direction and for large lepton pair invariant mass. In this kinematical region, the leading-twist amplitude factorises into a short-distance matrix element, long-distance dominated antiproton Distribution Amplitudes and proton to pion Transition Distribution Amplitudes (TDA). Using a modelling inspired from the chiral limit for these TDAs, we obtain a first estimate of this cross section, thus demonstrating that this process can be measured at GSI-FAIR.

description: Machine learning with artificial neural networks is revolutionizing science. The most advanced challenges require discovering answers autonomously. This is the domain of reinforcement learning, where control strategies are improved according to a reward function. The power of neural-network-based reinforcement learning has been highlighted by spectacular recent successes, such as playing Go, but its benefits for physics are yet to be demonstrated. Here, we show how a network-based "agent" can discover complete quantum-error-correction strategies, protecting a collection of qubits against noise. These strategies require feedback adapted to measurement outcomes. Finding them from scratch, without human guidance, tailored to different hardware resources, is a formidable challenge due to the combinatorially large search space. To solve this, we develop two ideas: two-stage learning with teacher/student networks and a reward quantifying the capability to recover the quantum information stored in a multi-qubit system. Beyond its immediate impact on quantum computation, our work more generally demonstrates the promise of neural-network-based reinforcement learning in physics.

description: The photon zero-mass hypothesis has been investigated for a long time using the frequency-dependent time delays of radio emissions from astrophysical sources. However, the search for a rest mass of the photon has been hindered by the similarity between the frequency-dependent dispersions due to the plasma and nonzero photon mass effects. Considering the contributions to the observed dispersion measure from both the plasma and nonzero photon mass effects, and assuming the dispersion induced by the plasma effect is an unknown constant, we obtain a robust limit on the photon mass by directly fitting a combination of the dispersion measures of radio sources. Using the observed dispersion measures from two statistical samples of extragalactic pulsars, here we show that at the 68\% confidence level, the constraints on the photon mass can be as low as $m_γ\leq1.51\times10^{-48}~\rm kg\simeq8.47\times10^{-13}~{\rm eV}/c^{2}$ for the sample of 22 radio pulsars in the Large Magellanic Cloud and $m_γ\leq1.58\times10^{-48}~\rm kg\simeq8.86\times10^{-13} {\rm eV}/c^{2}$ for the other sample of 5 radio pulsars in the Small Magellanic Cloud, which are comparable with that obtained by a single extragalactic pulsar. Furthermore, the statistical approach presented here can also be used when more fast radio bursts with known redshifts are detected in the future.
