description: Baikal-GVD is a gigaton-scale neutrino observatory under construction in Lake Baikal. It currently produces about 100 GB of data every day. For their automatic processing, the Baikal Analysis and Reconstruction software (BARS) was developed. At the moment, it includes such stages as hit extraction from PMT waveforms, assembling events from raw data, assigning timestamps to events, determining the position of the optical modules using an acoustic positioning system, data quality monitoring, muon track and cascade reconstruction, as well as the alert signal generation. These stages are implemented as C++ programs which are executed sequentially one after another and can be represented as a directed acyclic graph. The most resource-consuming programs run in parallel to speed up processing. A separate Python package based on the luigi package is responsible for program execution control. Additional information such as the program execution status and run metadata are saved into a central database and then displayed on the dashboard. Results can be obtained several hours after the run completion.

description: Pädophile Menschen werden in der Gesellschaft stigmatisiert und tabuisiert. Grund dafür stellt die mangelnde Aufklärung über das Störungsbild Pädophilie dar. Es wird nicht zwischen der Pädophilie und der Pädosexualität differenziert. Mit einer adäquaten Prävention kann es gelingen , dass Menschen mit pädophiler Neigung den richtigen Umgang mit dieser Paraphilie erlernen. Diese Arbeit beschäftigt sich mit Störungsbild Pädophilie und klärt über mögliche präventive Maßnahmen auf, dass aus einer Pädophilie keine Pädosexualität werden muss und ob ein Leben mit Pädophilie in der Gesellschaft möglich ist.

description: The Distributed Coordination Function (DCF) aims at fair and efficient medium access in IEEE 802.11. In face of its success, it is remarkable that there is little consensus on the actual degree of fairness achieved, particularly bearing its impact on quality of service in mind. In this paper we provide an accurate model for the fairness of the DCF. Given M greedy stations we assume fairness if a tagged station contributes a share of 1/M to the overall number of packets transmitted. We derive the probability distribution of fairness deviations and support our analytical results by an extensive set of measurements. We find a closed-form expression for the improvement of long-term over short-term fairness. Regarding the random countdown values we quantify the significance of their distribution whereas we discover that fairness is largely insensitive to the distribution parameters. Based on our findings we view the DCF as emulating an ideal fair queuing system to quantify the deviations from a fair rate allocation. We deduce a stochastic service curve model for the DCF to predict packet delays in IEEE 802.11. We show how a station can estimate its fair bandwidth share from passive measurements of its traffic arrivals and departures.

description: Various types of topological defects in graphene are considered in the framework of the continuum model for long-wavelength electronic excitations, which is based on the Dirac--Weyl equation. The condition for the electronic wave function is specified, and we show that a topological defect can be presented as a pseudomagnetic vortex at the apex of a graphitic nanocone; the flux of the vortex is related to the deficit angle of the cone. The cases of all possible types of pentagonal defects, as well as several types of heptagonal defects (with the numbers of heptagons up to three, and six), are analyzed. The density of states and the ground state charge are determined.

description: An exactly solvable model for the decoherence of one and two-qubit states interacting with a spin-bath, in the presence of a time-dependent magnetic field is studied. The magnetic field is static along $\hat{z}$ direction and oscillatory in the transverse plane. The transition probability and Rabi oscillations between the spin-states of a single qubit is shown to depend on the size of bath, the distribution of qubit-bath couplings and the initial bath polarization. In contrast to the fast Gaussian decay for short times, the polarization of the qubit shows an oscillatory power-law decay for long times. The loss of entanglement for the maximally entangled two-qubit states, can be controlled by tuning the frequency of the rotating field. The decay rates of entanglement and purity for all the Bell-states are same when the qubits are non-interacting, and different when they are interacting.

description: Semiparametric joint models of longitudinal and competing risks data are computationally costly and their current implementations do not scale well to massive biobank data. This paper identifies and addresses some key computational barriers in a semiparametric joint model for longitudinal and competing risks survival data. By developing and implementing customized linear scan algorithms, we reduce the computational complexities from $O(n^2)$ or $O(n^3)$ to $O(n)$ in various components including numerical integration, risk set calculation, and standard error estimation, where $n$ is the number of subjects. Using both simulated and real world biobank data, we demonstrate that these linear scan algorithms generate drastic speed-up of up to hundreds of thousands fold when $n>10^4$, sometimes reducing the run-time from days to minutes. We have developed an R-package, FastJM, based on the proposed algorithms for joint modeling of longitudinal and time-to-event data with and without competing risks, and made it publicly available on the Comprehensive R Archive Network (CRAN).

description: We present an optimization scheme that employs a Genetic Algorithm (GA) to determine the properties of low-lying nucleon excitations within a realistic photo-pion production model based upon an effective Lagrangian. We show that with this modern optimization technique it is possible to reliably assess the parameters of the resonances and the associated error bars as well as to identify weaknesses in the models. To illustrate the problems the optimization process may encounter, we provide results obtained for the nucleon resonances $Δ$(1230) and $Δ$(1700). The former can be easily isolated and thus has been studied in depth, while the latter is not as well known experimentally.

description: Participation as an analytic concept was first introduced by Goffman (1981) in his work on footing. Goffman was critical of the traditional models representing the categorical participant roles as only speakers and hearers. By considering various forms of subordinate communication such as byplay, crossplay and sideplay, he showed the inadequacy of the dyadic speaker-hearer role structure and decomposed both speaker and hearer into a range of different kinds of participant roles.

description: We derive the linearly perturbed matching conditions between a Schwarzschild spacetime region with stationary and axially symmetric perturbations and a FLRW spacetime with arbitrary perturbations. The matching hypersurface is also perturbed arbitrarily and, in all cases, the perturbations are decomposed into scalars using the Hodge operator on the sphere. This allows us to write down the matching conditions in a compact way. In particular, we find that the existence of a perturbed (rotating, stationary and vacuum) Schwarzschild cavity in a perturbed FLRW universe forces the cosmological perturbations to satisfy constraints that link rotational and gravitational wave perturbations. We also prove that if the perturbation on the FLRW side vanishes identically, then the vacuole must be perturbatively static and hence Schwarzschild. By the dual nature of the problem, the first result translates into links between rotational and gravitational wave perturbations on a perturbed Oppenheimer-Snyder model, where the perturbed FLRW dust collapses in a perturbed Schwarzschild environment which rotates in equilibrium. The second result implies in particular that no region described by FLRW can be a source of the Kerr metric.

description: Der Prüf- und Messdienst der Bundesnetzagentur soll für die erleichterte Überprüfung von Sendefunkanlagen und für die Funkstörungsbearbeitung mit eigenen Messdrohnen ausgerüstet werden. Diese müssen über eine zuverlässige Positions- und Richtungsbestimmung ausgerüstet sein, welche durch das Global Navigation Satelite (GNSS) realisiert werden soll. Dazu wurden in dieser Arbeit in GNSS-Empfänger der Firma u-blox untersucht und erprobt, mit welchen es durch eine Moving-Base-Anwendung und der Anbringung von zwei miteinander verbundenen Empfängern auf der Drohne möglich ist, einen GNSS-Kompass zur Richtungsbestimmung aufzubauen. Für die Erprobung der Empfänger wurden Testmessungen zur Positions- und Richtungsgenauigkeit durchgeführt, wobei u.a. verschiedene Korrekturdienste einbezogen wurden. Die Messungen erfolgten sowohl statisch bei der Positionsbestimmung als auch dynamisch bei der Richtungsbestimmung. Für die Auswertung der Messungen und für die Integration der Empfänger auf Drohnen oder Messfahrzeugen des PMD wurde zudem eine Schnittstellenprogrammierung über das proprietäre UBX-Protokoll durchgeführt. Bzgl. der Richtungsbestimmung konnte eine Eignung der Empfänger für den Einsatz auf den Drohnen anhand der Testergebnisse festgestellt werden. Für eine absolute Positionsgenauigkeit im Subdezimeterbereich hat sich die RTK-korrekturgestützte Positionsmessung mit dem SAPOS-Korrekturdienst als beste Lösung erwiesen.

description: With the rise in use of social media to promote branded products, the demand for effective influencer marketing has increased. Brands are looking for improved ways to identify valuable influencers among a vast catalogue; this is even more challenging with "micro-influencers", which are more affordable than mainstream ones but difficult to discover. In this paper, we propose a novel multi-task learning framework to improve the state of the art in micro-influencer ranking based on multimedia content. Moreover, since the visual congruence between a brand and influencer has been shown to be good measure of compatibility, we provide an effective visual method for interpreting our models' decisions, which can also be used to inform brands' media strategies. We compare with the current state-of-the-art on a recently constructed public dataset and we show significant improvement both in terms of accuracy and model complexity. The techniques for ranking and interpretation presented in this work can be generalised to arbitrary multimedia ranking tasks that have datasets with a similar structure.

description: We present a simple bijection between Baxter permutations of size $n$ and plane bipolar orientations with n edges. This bijection translates several classical parameters of permutations (number of ascents, right-to-left maxima, left-to-right minima...) into natural parameters of plane bipolar orientations (number of vertices, degree of the sink, degree of the source...), and has remarkable symmetry properties. By specializing it to Baxter permutations avoiding the pattern 2413, we obtain a bijection with non-separable planar maps. A further specialization yields a bijection between permutations avoiding 2413 and 3142 and series-parallel maps.

description: Reindeer (Eangifev tarandus tarandus L.) winter rangeland in the Tuktoy-aktuk Peninsula area, N.W.T., was studied using a ground-truth/large-scale (1:1,400-1:3,400) remote sensing program. Ground-truth of vegetation, soils and general environment was conducted at 112 representative sites located throughout the study area. Two-way indicator species analysis (TWINSPAN) of vegetation cover by 420 plant taxa assigned sites among four broadly-defined 'vegetation groups'. The vegetation groups could be considered as ecosystemic units since they are also differentiated by a range of site parameters, including slope position classes, general cover features measured in 10 m x 10 m plots, mineral soil texture classes, the occurrence of organic soils and ice-wedge polygons, and certain soil physical and chemical parameters. Lichens are of particular importance as the winter diet mainstay for the reindeer, and differences among vegetation groups are reflected by dominant lichen taxa, and lichen ground cover, biomass and standing crop estimates. Lichen cover at sites ranged up to 89.3% and, for sites where lichen cover >20%, standing crop ranged from 194.4 to 6,377.6 kg.ha⁻¹. Large-scale colour-infrared (CIR) 70 mm stereo photographs were acquired throughout the study area along 44 flightlines, and a total of 1,469 photo-frames were interpreted and inventoried. Data were summarized according to 7 reindeer management zones defined within the study area.

The library improves on previous codes by many orders of magnitude in single-core performance, can be parallelized on a large number of CPUs and on the GPU, and can be used interactively. We describe the techniques used in the code and provide many usage examples. As first applications, we use $\mathtt{\text{sl2cfoam-next}}$ to complete the numerical test of the Lorentzian single-vertex asymptotics and to confirm the presence of the "flatness problem" of spin foam models in the BF and EPRL cases.

description: Der öffentliche Raum Breslaus ist ein besonders spannendes Untersuchungsfeld für die Geschichts- und Kulturwissenschaften. Die Studie von Jacek Grębowiec „Inschriften im öffentlichen Raum in Wrocław/Breslau" führt am Medium der schriftgebundenen Ikonosphäre Breslaus die Komplexität historischer Beschriftungen im Breslauer Stadtraum vor Augen und verweist zugleich auf deren neue Aktualität. Die Stadtlandschaft Breslaus erlebte nach den großflächigen Zerstörungen in den letzten Monaten des Zweiten Weltkrieges und dem nahezu vollständigen Austausch der Stadtbevölkerung in den Jahren 1945–47 einen vielschichtigen Transformationsprozess. Das ehemals deutsche Breslau sollte durch eine selektive Wiederaufbau- und Abrisspolitik auch symbolisch eine polnische Stadt werden. Sehr anschaulich beschreibt Gregor Thum diesen geschichtspolitischen und architektonischen Transformationsprozess in seinem mehrfach aufgelegten und übersetzten Buch „Die fremde Stadt. Breslau 1945" [1]. Die symbolische und materielle Neudefinition Breslaus ist dabei kein abgeschlossenes Phänomen, sondern bis heute im Wandel begriffen. Nach Phasen der stark politisierten Inszenierung bzw. der Entfernung von Gebäuden, Denkmälern, Friedhöfen, Museumsobjekten und eben auch von Inschriften, ist seit dem Ende der polnischen Volksrepublik ein gegenläufiger Trend zu beobachten. Die Spuren der lokalen Geschichte in ihrer Gesamtheit werden als kulturelles Erbe Breslaus angenommen und als Tradition einer außergewöhnlichen ostmitteleuropäischen Stadt herausgestellt. Die wenigen verbliebenen deutschsprachigen Inschriften auf barocken Gedenktafeln an Kirchen und Bürgerhäusern, aber auch auf Denkmälern aus späterer Zeit erhalten hier einen besonderen Symbolwert. Am Beispiel ausgewählter lateinischer und deutscher Inschriften auf Breslauer Denkmälern und Hauswänden entschlüsselt der Polonist Jacek Grębowiec die komplexen Bedeutungsinhalte wie auch die historischen Hintergründe dieser Schriftzeugnisse im heutigen Breslauer Stadtraum.

description: This paper addresses the global molecular gas properties of a representative sample of galaxies hosting low-luminosity quasistellar objects. An abundant supply of gas is necessary to fuel both the active galactic nucleus and any circum-nuclear starburst activity of QSOs. We selected a sample of nearby low-luminosity QSO host galaxies that is free of infrared excess biases. All objects are drawn from the Hamburg-ESO survey for bright UV-excess QSOs, have DEC>-30 degrees and redshifts that do not exceed z=0.06. The IRAM 30m telescope was used to measure the CO(1-0) and CO(2-1) transition in parallel. 27 out of 39 galaxies in the sample have been detected. The molecular gas masses of the detected sources range from 0.4E9 M_sun to 9.7E9 M_sun. We can confirm that the majority of galaxies hosting low-luminosity QSOs are rich in molecular gas. The properties of galaxies hosting brighter type I AGN and circumnuclear starformation regions differ from the properties of galaxies with fainter central regions. The overall supply of molecular gas and the spread of the line width distribution is larger. When comparing the far-infrared with the CO luminosities, the distribution can be separated into two different power-laws: one describing the lower activity Seyfert I population and the second describing the luminous QSO population. The separation in the L_FIR/L'_CO behavior may be explainable with differing degrees of compactness of the emission regions. We provide a simple model to describe the two power-laws. The sample studied in this paper is located in a transition region between the two populations.

description: Ostatni bunt [The Last Rebellion] is Marek Wierzbicki's most recent book dealing with Polish youth under communist rule. It tackles the specific problem of youth opposition to communism during the regime's final decade of existence. The book represents a first attempt at an in-depth historical discussion and analysis of the subject, which thus far has been mostly absent in the narrative. The importance of the topic is due to the fact that—as the author emphasises—in this period at least four hundred youth organisations, groups, and movements at schools and universities were politically active beyond the control of the regime. There would never again be such a degree of politicisation and activity among Poland's youth after the demise of communism.

description: In global efforts to reduce harmful greenhouse gas emissions from the transport sector, novel bio-hybrid liquid fuels from renewable energy and carbon sources can be a major form of energy for future propulsion systems due to their high energy density. A fundamental understanding of the spray and mixing performance of the new fuel candidates in combustion systems is necessary to design and develop the fuels for advanced combustion concepts. In the fuel design process, a large number of candidates is required to be screened to arrive at potential fuels for further detailed investigations. For such a screening process, three-dimensional (3D) simulation models are computationally too expensive and hence unfeasible. Therefore, in this paper, we present a fast, reduced-order model (ROM) for inert sprays. The model is based on the cross-sectionally averaged spray (CAS) model derived by Wan (1997) from 3D multiphase equations. The original model was first tested against a wide range of conditions and different fuels. The discrepancies between the CAS model and experimental data are addressed by integrating state-of-the-art breakup and evaporation models. A transport equation for vapor mass fraction is proposed, which is important for evaporation modeling. Furthermore, the model is extended to consider polydisperse droplets by modeling the droplet size distribution by commonly used presumed probability density functions, such as Rosin-Rammler, lognormal, and gamma distributions. The improved CAS model is capable of predicting trends in the macroscopic spray characteristics for a wide range of conditions and fuels. The computational cost of the CAS model is lower than the 3D simulation methods by up to 6 orders of magnitude depending on the method. This enables the model to be used not only for the rapid screening of novel fuel candidates, but also for other applications, where ROMs are useful.

description: Baryons with three heavy quarks are the last missing pieces of the lowest-lying baryon multiplets in the quark model after the discovery of doubly heavy baryons. In this work, we study nonleptonic weak decays of triply heavy baryons $Ω_{ccc}^{++}$, $Ω_{bbb}^{-}$, $Ω_{ccb}^{+}$, and $Ω_{cbb}^{0}$. Decay amplitudes for various processes have been parametrized in terms of the SU(3) irreducible nonperturbative amplitudes. A number of relations for the partial decay widths can be deduced from these results that can be examined in future. Some decay channels and cascade decay modes which likely to be used to reconstruct the triply heavy baryons have been also listed.

description: Potrzeba analizy procesów nauczania i uczenia się osób starszych jest niezwykle istotną kwestią poruszaną aktualnie przez środowisko andragogów i gerontologów społecznych. Za sprawą zmiany praktyk uczenia się dorosłych w Polsce - przejawiających się m.in. w postaci intensywnego rozwoju ilościowego uniwersytetów trzeciego wieku (UTW), klubów seniora i proseniorskich organizacji pozarządowych - wzrasta konieczność reorientacji praktycznego spojrzenia na mechanizmy uczenia się i nauczania osób starszych. Recenzowana publikacja składa się z pięciu części. W pierwszej z nich scharakteryzowane zostało nauczanie i uczenie się w pryzmacie wielowątkowych uwarunkowań procesu edukacyjnego. Autorka analizując zagadnienie edukacji w zakresie języków obcych celowo używa pojęć uczenie się i nauczanie, które nierozerwalnie ze sobą powiązane, tworzą złożony system czynników zależnych i niezależnych od osoby nabywającej nowe kompetencje. Anna Jaroszewska jako językoznawca nie tylko opisuje dydaktyczne i glottodydaktyczne przesłanki procesu nabywania umiejętności językowych, lecz także sięga do ważnych wątków (demograficznych, społecznych i kulturowych) warunkujących psychospołeczne funkcjonowanie osób starszych. Projektując proces badawczy autorka zauważyła, że w polskiej przestrzeni badawczej można dostrzec brak publikacji odnoszących się do opisywanego zagadnienia. Czynnik ten sprawił, że konieczność aktualnego i szerokiego spojrzenia na omawianą tematykę stał się jeszcze bardziej zasadny. Z książki Jaroszewskiej można wysunąć wniosek, że polska „geragogika filologiczna" na tle innych krajów europejskich jawi się jako młoda, nierozwinięta subdyscyplina, pomimo faktu iż badania w tym obszarze zostały zapoczątkowane w krajach zachodnich już w latach 70-tych XX wieku.

description: Die seit 2012 in elektronischer Fassung vorliegende Monographie des mit der University of Edinburgh verbundenen Historikers David B. Kaufman über die polnisch-jüdischen Beziehungen im Kontext von polnischer Staatsgründung und Versailler Friedenskonferenz ist das Ergebnis umfangreicher Recherchen in polnischen, britischen und US-amerikanischen Archiven. Der Schwerpunkt liegt dabei auf staatlichen Überlieferungen für die polnische Seite, während nicht-staatliche Überlieferungen aus der westlichen Diaspora den wichtigsten Quellenkorpus für die Darstellung jüdischer Sichtweisen ausmachen. Die Studie, auf einer Dissertation an der University of Stirling basierend, gliedert sich in eine Einleitung, fünf Kapitelund eine Zusammenfassung, ergänzt um zwei Dokumentenanhänge. Dabei handelt es sich um den Minderheitenschutzvertrag, den Polen mit der Entente am 26. Juni 1919 schloss sowie um einen Brief des Präsidenten der Friedenskonferenz, Georges Clemenceau, an Ignacy Paderewski, Leiter der polnischen Delegation, am Pariser Tagungsort.

description: The modern Western democracies face two major challenges: the pension systems and the financing of political campaigns. Almost all contemporary political and economic struggles revolve around these two issues. The first one is treated at length by the sociological and economic literature. The second, however, still lacks analysis because it contains an element that hinders its clarity: human relations. In other words, the relationship between politicians and business people, among bureaucrats and those who are dependent on the state or regulatory decisions. In this field, of course, not always impersonal decisions prevail [1]. Networks and Institutions in Europe's Emerging Markets is a contribution to expand the research on the topic and add a unique perspective. Roger Schoenman revisits both paradigmatic success stories and frequently cited laggards of political and economic reform in post-communist Europe between 1989 and 2005 by focusing on the neglected role of networks between firms and political parties. The author seeks to understand how the configuration of networks determined the institutional trajectories of post-socialist states.

description: The discovery of gravitational waves (GWs) from the compact binary components by LIGO/Virgo Collaboration provides an unprecedented opportunity for testing gravity in the strong and highly dynamical field regime of gravity. Currently a lot of model-independent tests have been performed by LIGO/Virgo Collaboration and no any significant derivation from general relativity has been found. In this paper, we study the parity violating effects on the propagation of GWs in the Nieh-Yan modified teleparallel gravity, a theory which modifies general relativity by a parity violating Nieh-Yan term. We calculate the corresponding parity violating waveform of GWs produced by the coalescence of compact binaries. By comparing the two circular polarization modes, we find the effects of the velocity birefringence of GWs in their propagation caused by the parity violation due to the Nieh-Yan term, which are explicitly presented in the GW waveforms by the phase modification. With such phase modifications to the waveform, we perform the full Bayesian inference with the help of the open source software {\texttt Bilby} on the GW events of binary black hole merges (BBH) in the LIGO-Virgo catalogs GWTC-1 and GWTC-2. We do not find any significant evidence of parity violation due to the parity violating Nieh-Yan term and thus place an upper bound on the energy scale $M_{\rm PV} < 6.5 \times 10^{-42} \; {\rm GeV}$ at 90\% confidence level, which represents the first constraint on the Nieh-Yan modified teleparallel gravity so far.

description: We present a complete analysis of the laser control of a model molecular system using both optimal control theory and adiabatic techniques. This molecule has a particular potential energy surface with a bifurcating region connecting three potential wells which allows a variety of processes such as isomerization, tunnelling or implementation of quantum gates on one or two qubits. The parameters of the model have been chosen so as to reproduce the main features of H3CO which is a molecule-benchmark for such dynamics. We show the feasibility of different processes and we investigate their robustness against variations of laser field. We discuss the conditions under which each method of control gives the best results. We also point out the relation between optimal control theory and local control.

description: We investigate the formation of dark vector localized structures in the presence of nonlinear polarization mode coupling in optical resonators subject to a coherent optical injection in the normal dispersion regime. This simple device is described by coupled Lugiato-Lefever equations. The stabilization of localized structures is attributed to a front locking mechanism. We show that in a multistable homogeneous steady-state regime, two branches of dark localized structures can coexist for a fixed value of the system parameters. These coexisting solutions possess different polarization states and different power peaks in the microresonator. We characterize in-depth their formation by drawing their bifurcation diagrams in regimes close to modulational instability and far from it. It is shown that both branches of localized structures exhibit a heteroclinic collapse snaking type of behavior. The coexistence of two vectorial branches of dark localized states is not possible without taking into account polarization degrees of freedom.

description: The author used synchrotron x-ray reflectivity to study the ion-size effect for alkali ions (Na$^+$, K$^+$, Rb$^+$, and Cs$^+$), with densities as high as $4 \times 10^{18}- 7 \times 10^{18}$ m$^{-2}$, suspended above the surface of a colloidal solution of silica nanoparticles in the field generated by the surface electric-double layer. According to the data, large alkali ions preferentially accumulate at the sol's surface replacing smaller ions, a finding that qualitatively agrees with the dependence of the Kharkats-Ulstrup single-ion electrostatic free energy on the ion's radius.

description: The description of the tunneling of a macroscopic variable in the presence of a bath of localized spins is a subject of great fundamental and practical interest, and is relevant for many solid-state qubit designs. Instead of focusing on the the "central spin" (as is most often done), here we present a detailed study of the dynamics of the nuclear spin bath in the Mn12-ac single-molecule magnet, probed by NMR experiments down to very low temperatures (T = 20 mK). We find that the longitudinal relaxation rate of the 55Mn nuclei in Mn12-ac becomes roughly T-independent below T = 0.8 K, and can be strongly suppressed with a longitudinal magnetic field. This is consistent with the nuclear relaxation being caused by quantum tunneling of the molecular spin, and we attribute the tunneling fluctuations to the minority of fast-relaxing molecules present in the sample. The transverse nuclear relaxation is also T-independent for T < 0.8 K, and can be explained qualitatively and quantitatively by the dipolar coupling between like nuclei in neighboring molecules. We also show that the isotopic substitution of 1H by 2H leads to a slower nuclear longitudinal relaxation, consistent with the decreased tunneling probability of the molecular spin. Finally, we demonstrate that, even at the lowest temperatures, the nuclear spins remain in thermal equilibrium with the lattice phonons, and we investigate the timescale for their thermal equilibration. After a review of the theory of macroscopic spin tunneling in the presence of a spin bath, we argue that most of our experimental results are consistent with that theory, but the thermalization of the nuclear spins is not.
