description: Several efforts have been seen claiming the lightweight block ciphers as a necessarily suitable substitute in securing the Internet of Things. Currently, it has been able to envisage as a pervasive frame of reference almost all across the privacy preserving of smart and sensor-oriented appliances. Different approaches are likely to be inefficient, bringing desired degree of security considering the easiness and surely the process of simplicity but security. Strengthening the well-known symmetric key and block dependent algorithm using either chaos motivated logistic map or elliptic curve has shown a far-reaching potential to be a discretion in secure real-time communication. The popular feature of logistic maps, such as the un-foreseeability and randomness often expected to be used in dynamic key-propagation in sync with chaos and scheduling technique towards data integrity. As a bit alternation in keys, able to come up with oversize deviation, also would have consequence to leverage data confidentiality. Henceforth it may have proximity to time consumption, which may lead to a challenge to make sure instant data exchange between participating node entities. In consideration of delay latency required to both secure encryption and decryption, the proposed approach suggests a modification on the key-origination matrix along with S-box. It has plausibly been taken us to this point that the time required proportionate to the plain-text sent while the plain-text disproportionate to the probability happening a letter on the message made. In line with that the effort so far sought how apparent chaos escalates the desired key-initiation before message transmission.

description: Understanding the electronic charge distribution around oxygen vacancies in transition metal and rare earth oxides is a scientific challenge of considerable technological importance. We show how significant information about the charge distribution around vacancies in cerium oxide can be gained from a study of high resolution crystal structures of higher order oxides which exhibit ordering of oxygen vacancies. Specifically, we consider the implications of a bond valence sum analysis of Ce$_{7}$O$_{12}$ and Ce$_{11}$O$_{20}$. To illuminate our analysis we show alternative representations of the crystal structures in terms of orderly arrays of co-ordination defects and in terms of flourite-type modules. We found that in Ce$_{7}$O$_{12}$, the excess charge resulting from removal of an oxygen atom delocalizes among all three triclinic Ce sites closest to the O vacancy. In Ce$_{11}$O$_{20}$, the charge localizes on the next nearest neighbour Ce atoms. Our main result is that the charge prefers to distribute itself so that it is farthest away from the O vacancies. This contradicts \emph{the standard picture of charge localisation} which assumes that each of the two excess electrons localises on one of the cerium ions nearest to the vacancy. This standard picture is assumed in most calculations based on density functional theory (DFT). Based on the known crystal structure of Pr$_{6}$O$_{11}$, we also predict that the charge in Ce$_{6}$O$_{11}$ will be found in the second coordination shell of the O vacancy. Although this review focuses on bulk cerium oxides our approach to characterising electronic properties of oxygen vacancies and the physical insights gained should also be relevant to surface defects and to other rare earth and transition metal oxides.

description: Since ancient times, cultures have maintained oral traditions by sharing stories in poetic form (Francis 2017). Although different traditions treat poetry according to their own thinking frameworks, most of them perform some sort of analysis that requires the extraction of stress patterns of lines or verses. Scansion, as this procedure is broadly referred to, is usually language dependent. On the assumption that modern context-dependent language models are able to retain the structural properties of text, this paper explores whether metrical patterns are part of the information encoded in the embedding spaces of text.

description: We present a multiscale approach to simulate the impact of a solid object on a liquid surface: upon impact a thin liquid sheet is thrown upwards all around the rim of the impactor while in its wake a large surface cavity forms. Under the influence of hydrostatic pressure the cavity immediately starts to collapse and eventually closes in a single point from which a thin, needle-like jet is ejected. Existing numerical treatments of liquid impact either consider the surrounding air as an incompressible fluid or neglect air effects altogether. In contrast, our approach couples a boundary-integral method for the liquid with a Roe scheme for the gas domain and is thus able to handle the fully \emph{compressible} gas stream that is pushed out of the collapsing impact cavity. Taking into account air compressibility is crucial, since, as we show in this work, the impact crater collapses so violently that the air flow through the cavity neck attains supersonic velocities already at cavity diameters larger than 1 mm. Our computational results are validated through corresponding experimental data.

description: Sm-doped BiFeO3 compacted powders with composition across the morphotropic phase boundary region were prepared by sol-gel method. Crystal structure, morphology and magnetic state of the compounds were analyzed as a function of dopant concentration, temperature and external pressure using synchrotron and laboratory X-ray diffraction, electron microscopy, Raman and Mossbauer spectroscopy. Application of external pressure shifts the phase transition from the rhombohedral structure to the nonpolar orthorhombic structure towards lower concentration of the dopant content, wherein the amount of the anti-polar orthorhombic phase notably decreases. Raman and Mossbauer spectroscopy data provides additional information about the structural distortion on local scale level which testifies faster formation of nonpolar orthorhombic phase and associated modification in the magnetic state in the compounds subjected to high pressure. Temperature increase leads to the structural transition to the nonpolar orthorhombic phase regardless the structural state at room temperature; furthermore, application of external pressure decreases the phase transition temperature.

description: From the time they are born, children develop emergent literacy in home and community settings (Teale et al., 2018). One of the ways caregivers support children's emergent literacy is by reading together—shared reading. Previous research has shown that caregivers exhibit interactional differences between reading informational picturebooks with children and reading fictional picturebooks (J. Anderson et al., 2004; Baldwin & Morrow, 2019; Price et al., 2009). Caregivers ask more questions and provide further explanations to children in reading informational picturebooks compared to reading fictional picturebooks. To explore this difference, this dissertation analyzed how caregivers’ knowledge of reading informational picturebooks are shared with children in caregiver-child interactions during shared reading activities. Drawing on sociocultural theory (Vygotsky, 1978) and bioecological perspective (Bronfenbrenner & Morris, 2007), caregiver-child interactions were interpreted as social interactions facilitated by an immediate family member within emergent literacy contexts. This dissertation investigated three families’ practices of shared reading of informational picturebooks through a qualitative case study. The three families’ surveys, reading logs, observations of reading informational picturebooks, and caregiver interviews were collected and analyzed. Findings demonstrate how caregivers utilized features of informational picturebooks while multimodally interacting with their child. Caregivers mostly incorporated visual features of informational picturebooks, and rarely organizational and supporting tools. Multimodal interactions between caregivers and children are observed across the shared reading practices which emphasize the nature of multimodal interactions. The findings contribute to understanding caregivers' and children’s multimodal interactions when reading informational picturebooks and how caregivers’ knowledge and experiences are embedded in their interactions. This dissertation identifies areas for literacy researchers to pursue in future research and suggests potential implications for encouraging caregivers’ use of informational picturebooks.

description: Dense active matter is gaining widespread interest due to its remarkable similarity with conventional glass-forming materials. However, active matter is inherently out-of-equilibrium and even simple models such as active Brownian particles (ABPs) and active Ornstein-Uhlenbeck particles (AOUPs) behave markedly differently from their passive counterparts. Controversially, this difference has been shown to manifest itself via either a speedup, slowdown, or non-monotonic change of the glassy relaxation dynamics. Here we rationalize these seemingly contrasting views on the departure from equilibrium by identifying the ratio of the short-time length scale to the cage length, i.e. the length scale of local particle caging, as a vital and unifying control parameter for active glassy matter. In particular, we explore the glassy dynamics of both thermal and athermal ABPs and AOUPs upon increasing the persistence time. We find that for all studied systems there is an optimum of the dynamics; this optimum occurs when the cage length coincides with the corresponding short-time length scale of the system, which is either the persistence length for athermal systems or a combination of the persistence length and a diffusive length scale for thermal systems. This new insight, for which we also provide a simple physical argument, allows us to reconcile and explain the manifestly disparate departures from equilibrium reported in many previous studies of dense active materials.

description: Nanoscale phase separation (NPS) characterized by particular types of correlated disorder plays an important role in the functionality of high temperature superconductors (HTS). Our results show that multiscale heterogeneity is an essential ingredient of quantum functionality in complex materials. Here, the interactions developing between different structural units cause dynamical spatiotemporal conformations with correlated disorder. Thus visualizing conformations landscape is needed for understanding the physical properties of complex matter and requires advanced methodologies based on high precision X ray measurements. We discuss the dynamical correlated disorder at nanoscale and the related functionality in oxygen doped perovskite superconducting materials

description: It is believed that some stars have two or more convection zones in close proximity near to the stellar photosphere. These zones are separated by convectively stable regions that are relatively narrow. Due to the close proximity of these regions it is important to construct mathematical models to understand the transport and mixing of passive and dynamic quantities. One key quantity of interest is a magnetic field, a dynamic vector quantity, that can drastically alter the convectively driven flows, and have an important role in coupling the different layers. In this paper we present the first investigation into the effect of an imposed magnetic field in such a geometry. We focus our attention on the effect of field strength and show that, while there are some similarities with results for magnetic field evolution in a single layer, new and interesting phenomena are also present in a three layer system.

description: Circular polarisation measurements of white dwarfs of various ages and spectral types are useful to understand the origin and evolution of the magnetic field in degenerate stars. In the latest stages of white dwarf evolution, when stars are so cool that spectral lines are no longer formed in the normal H- or He-dominated atmospheres, magnetic fields can be probed only by means of circular polarimetry of the continuum. The study of the fields of featureless DC white dwarfs may reveal whether Ohmic decay acts on magnetic white dwarfs, or if magnetic fields continue to be generated even several billion years after white dwarf formation. Compared to spectropolarimetry, broad-band circular polarisation measurements have the advantage of reaching a higher accuracy in the continuum, with the potential of detecting magnetic fields as weak as a fraction of a MG in DC stars, if the telescope size is adequate for the star's magnitude. Here we present the results of a first (short) observing campaign with the DIPol-UF polarimeter, which we have used to measure broad-band circular polarisation of white dwarfs. Our observing run was in part aimed to fully characterise the instrument, and in part to study the relationship between magnetic field strength (when known from spectropolarimetry) and circular polarisation of the continuum. We also observed a small number of previously unexplored DC white dwarfs, and we present the discovery of two new magnetic white dwarfs of spectral class DC, probably the first discovery of this kind made with broad-band circular polarimetric techniques since the late 1970s. We also discuss the characteristics of our instrument, and predict the level of polarimetric accuracy that may be reached as a function of stellar magnitude, exposure time, and telescope size.

A comparison of six methods of stretch on the active range of hip flexion
Creators: name: Hartley, Sandra Jean
Publisher: name: University of British Columbia
Year: 2010

description: Basically all methods of stretching can be termed ACTIVE or PASSIVE in terms of the type of the range of motion acquired. Active stretching methods require that the range of movement be made voluntarily, while passive stretching methods refer to movement through a range due to external force such as gravity or manual assistance. It was the purpose of this study to investigate the effects of six methods of stretch on the active range of right hip flexion. The sample consisted of 119 volunteer college women in physical education at the University of British Columbia. Approximately twenty subjects were randomly assigned to each of seven treatment groups by pairs. In addition to the Control group, six exercise groups were taught various stretching regimens to be practiced ten minutes with a partner three times a week for three weeks. All subjects were measured before and after the study as well as before and after exercise on the first day of each week. The active range of right hip flexion was measured by the Leighton Flexometer and the strength of hip flexion at the 45 degree angle was measured by a cable tensiometer. All groups increased in active range of hip flexion as indicated by the mean gains, including the Control group. The following hypotheses were tested for significance at the .05 level and were rejected. 1. Active stretching methods give a greater improvement in active range of hip flexion than do passive methods of stretching. 2. The method, Active Proprioceptive Neuromuscular Facilitation, gives a greater improvement in active range of right hip flexion than does the method, Ballistic and Hold. Active stretching methods did not contribute significantly better to active range over passive methods, nor did the Active PNF method and Ballistic and Hold method show significant differences in their contribution to active range. Since passive methods of stretching contributed as well as active methods to active range of hip flexion, it is apparent that theoretically for active range of motion, it may be as important to reduce the resistance of the muscle being stretched as to increase the strength of the active opposing muscle. The results of this study indicate that both active and passive methods of stretching are effective in increasing active range of motion. The Relaxation method contributed significantly better than other passive methods to active range of hip flexion apparently due to a more effective reduced resistance from the contractile component of the muscle. The strength of hip flexion as measured at the 45 degree angle was not differentially improved by the various exercise treatments for the probable reason that the angle at which the strength was measured was well below the range at which specific strength gains might have taken place.

description: It is well known that disordered relaxor ferroelectrics exhibit local polar correlations. The origin of localized fields that disrupt long range polar order for different substitution types, however, is unclear. Currently, it is known that substituents of the same valence as Ti4+ at the B-site of barium titanate lattice produce random disruption of Ti-O-Ti chains that induces relaxor behavior. On the other hand, investigating lattice disruption and relaxor behavior resulting from substituents of different valence at the B-site is more complex due to the simultaneous occurrence of charge imbalances and displacements of the substituent cation. The existence of an effective charge mediated mechanism for relaxor behavior appearing at low (< 10%) substituent contents in heterovalent modified barium titanate ceramics is presented in this work. These results will add credits to the current understanding of relaxor behavior in chemically modified ferroelectric materials and also acknowledge the critical role of defects (such as cation vacancies) in lattice disruption, paving the way for chemistry-based materials design in the field of dielectric and energy storage applications.

description: Recent transport experiments in the original cuprate high temperature superconductor, {La$_{2-x}$Ba$_x$CuO$_4$}, have revealed a remarkable sequence of transitions and crossovers which give rise to a form of dynamical dimensional reduction, in which a bulk crystal becomes essentially superconducting in two directions while it remains poorly metallic in the third. We identify these phenomena as arising from a distinct new superconducting state, the "striped superconductor," in which the superconducting order is spatially modulated, so that its volume average value is zero. Here, in addition to outlining the salient experimental findings, we sketch the order parameter theory of the state, stressing some of the ways in which a striped superconductor differs fundamentally from an ordinary (uniform) superconductor, especially concerning its response to quenched randomness. We also present the results of DMRG calculations on a model of interacting electrons in which sign oscillations of the superconducting order are established. Finally, we speculate concerning the relevance of this state to experiments in other cuprates, including recent optical studies of {La$_{2-x}$Sr$_x$CuO$_4$} in a magnetic field, neutron scattering experiments in underdoped {YBa$_2$Cu$_3$O$_{6+x}$}, and a host of anomalies seen in STM and ARPES studies of {Bi$_2$Sr$_2$CaCu$_2$O$_{8+δ} $}.

Analyzing the Effects of the COVID-19 Pandemic on Compassion Fatigue in an Urban Emergency Department
Creators: name: Oei, Courtney Elizabeth
Publisher: name: University of Illinois at Chicago
Year: 2021
Subjects: Uncategorized

description: BACKGROUND: The emergency department is a high-stress environment where healthcare workers are repeatedly exposed to patients’ physical and emotional traumas. This often leads to the development of compassion fatigue (CF), which is the loss of empathy that develops directly from exposure to trauma. It is comprised of three components: burnout, secondary traumatic stress, and compassion satisfaction (Hinderer et al. 2014; Harris 2015). During the COVID-19 pandemic, the constant COVID-19 exposure and high volumes of acute critically ill or injured patients, results in a prolonged stress environment that could potentially increase CF in healthcare workers. METHODS: The ProQol-5 was used to measure CF across the three components (Figley 1995; Stamm 2010) at three time points: January 2020, July 2020, and January 2021. Univariate and bivariate analyses were used to evaluate the three CF components across different demographics. A generalized linear regression was used to assess which predictors influence CF when adjusted with collection date and role. RESULTS: Resident/Fellow/APNs overall experienced an increase in burnout, secondary traumatic stress, as well as compassion satisfaction. Both attending physician and nursing roles experienced an overall increase in burnout and secondary traumatic stress, while simultaneously experiencing a decrease in compassion satisfaction. ERT/MAs and supportive clinical staff had high mean burnout scores from the beginning of this study and maintained the level throughout the three collection dates. In the multivariable analysis, all three components are significantly different from the start of the study to the end of the study, with a p-value of <0.05. DISCUSSION: Overall, there was an increase in CF during this study. Characterized by the increase in burnout and secondary traumatic stress, accompanied with the overall decrease in compassion satisfaction, when adjusting for indicators such as gender, age, years worked with trauma patients and years worked in the role, the increase in CF along the COVID-19 timeline suggests as the pandemic ensued, CF increased among our healthcare workers.

description: The perovskite (1-x)YMnO$_3$-xBiFeO$_3$ binary system is very promising because of its multiferroic end members. Nanocrystalline phases have been recently obtained by mechanosynthesis across the system, and the perovskite structural evolution has been described. Two continuous solid solutions with orthorhombic Pnma and rhombohedral R3c symmetries were found, which coexist within a broad compositional interval of 0.5 < x < 0.9. This might be a polar-nonpolar morphotropic phase boundary region, at which strong phase-change magnetoelectric responses can be expected. A major issue is phase decomposition at moderate temperatures that highly complicates ceramic processing. This is required for carrying out a sound electrical characterization and also for their use in devices. We present here the application of Spark Plasma Sintering to the ceramic processing of YMnO$_3$-BiFeO$_3$ phases. This advanced technique, when combined with nanocrystalline powders, allowed densifying phases at reduced processing temperatures and times, so that perovskite decomposition was avoided. Electrical measurements were accomplished, and the response was shown to be mostly dominated by conduction. Nonetheless, the intrinsic dielectric permittivity was obtained, and a distinctive enhancement in the phase coexistence region was revealed. Besides, Rayleigh-type behaviour characteristic of ferroelectrics was also demonstrated for all rhombohedral phases. Magnetic characterization was performed in this region, and antiferromagnetism was shown.

description: Using 605/fb of data collected at the Upsilon(4S) resonance we present a measurement of the inclusive radiative B-meson decay channel, B to X_s gamma. For the lower photon energy thresholds of 1.7, 1.8, 1.9 and 2.0GeV, as defined in the rest frame of the B-meson, we measure the partial branching fraction and the mean and variance of the photon energy spectrum. At the 1.7GeV threshold we obtain the partial branching fraction BF(B to X_s gamma) = (3.45 +/- 0.15 +/- 0.40) x 10^-4, where the errors are statistical and systematic.

title: Silent Testing for Safety Validation of Automated Driving in Field Operation
Creators: name: Wang, Cheng
Publisher: name: UNSPECIFIED
Year: 2021

description: The safety validation of automated vehicles is currently a major challenge, even though substantial achievements have been made. The credibility of the results of conventional approaches such as the real-world testing or the simulation-based testing is questioned despite enormous testing effort. Therefore, new approaches for safety assurance with a high degree of credibility, adaptability and applicability are thus pursued. Under this circumstance, the approach “Virtual Assessment of Automation in Field Operation” (VAAFO) for testing automated vehicles is motivated. The key idea of this approach is that an instance is in charge of driving a vehicle, while a virtual automated vehicle runs in parallel in a virtual world, receiving real sensor inputs but separated from the real actuators. The instance in charge in the real world can be either a human driver or an automated precursor or representative system. Thus, the virtual automated vehicle and the instance in charge make decisions simultaneously but independently. Based on this working principle, the driving function of an automated vehicle can be tested under real conditions without bringing any additional risks. The goal of the work is to develop and implement the approach and finally to determine its contribution to the safety validation of automated vehicles. During the development and implementation of the approach, four research questions are studied. How to guarantee a valid environmental representation for the virtual vehicle is the first research focus. Since the objects detected by sensors are related to the instance in charge, they cannot be directly used for the virtual vehicle in the case of state deviations between the instance in charge and the virtual vehicle. Therefore, the mapping of the environmental representation in the virtual world is investigated. To answer this research question, a coordinate transformation is performed, and the lifetime and the birth cycle of virtual vehicles as two key parameters are introduced. How to evaluate the safety of the virtual vehicle and identify critical scenarios is the second research focus. To address the second research question, triggers are derived and substantiated by a developed criticality index. The third research focus is the development of a suitable ring buffer and a modular framework for the approach. The determination of the coverage degree of the approach is the last research focus. In order to derive the application scope of the approach, simulations and real-world tests are performed. Finally, considering the coverage degree and the limits of applicability, the role of the VAAFO approach in the whole family of approaches for the safety validation of automated vehicles is determined. Lastly, further studies for the future are pointed out.

Bispectrum signatures of a modified vacuum in single field inflation with a small speed of sound

description: Deviations from the Bunch-Davies vacuum during an inflationary period can leave a testable imprint on the higher-order correlations of the CMB and large scale structures in the Universe. The effect is particularly pronounced if the statistical non-Gaussianity is inherently large, such as in models of inflation with a small speed of sound, e.g. DBI. First reviewing the motivations for a modified vacuum, we calculate the non-Gaussianity for a general action with a small speed of sound. The shape of its bispectrum is found to most resemble the 'orthogonal' or 'local' templates depending on the phase of the Bogolyubov parameter. In particular, for DBI models of inflation the bispectrum can have a profound 'local' template feature, in contrast to previous results. Determining the projection into the observational templates allows us to derive constraints on the absolute value of the Bogolyubov parameter. In the small sound speed limit, the derived constraints are generally stronger than the existing constraint derived from the power spectrum. The bound on the absolute value of the Bogolyubov parameter ranges from the 10^-6 to the 10^-3 level for H/Λ_c = 10^-3, depending on the specific details of the model, the sound speed and the phase of the Bogolyubov parameter.

Understanding the Ion Transport Through the Charged Nanochannel Systems

description: Here I present a comprehensive study of the ion transport properties through the charged nanochannel systems was done by developing several types of boron nitride nanostructures including the CVD deposited boron nitride- alumina oxide (BN-AAO) membranes and boron nitride – SiO2 nanochannels, lamellar boron nitride flake membranes, and 3-nm boron nitride nanotube dispersed polyurethane composite (BNNT-polyurethane) membranes. Membrane transport properties through the different nanostructures were studied by testing the effect of surface properties and solution properties on the ion transport. We systematically investigate the effect of membrane structure (pore size, pore density and membrane morphologies) and the surface properties (surface defects, crystal structures and surface chare density) on the ion transport properties via various experimental and numerical methods. The membrane morphology was characterized experimentally by scanning electronic microscope (SEM) and atomic force microscope (AFM) while the surface properties were measured using Raman spectroscopy, X-Ray Diffraction (XRD) and conductance-based surface charge density measurement. The ion transport properties of the membrane were measured by a number for diffusion-based measurements and electrochemical methods. Molecular dynamic (MD) simulation studies were also employed to help investigate the interaction between membranes and the ions species. After understanding the transport characteristics, the BN-AAO membranes were explored for their applications for osmotic power generation while the h-BN lamellar membranes and BNNT-polyurethane membranes were tested for their ion separation and water purification performance. The BN-AAO membranes show an improved performance compared to most other nanofluidic reverse electrodialysis systems while the h-BN flake membranes show a high rejection with a better permeability than most other 2D-layered membranes.

description: This paper presents a small-area monolithic pixel detector ASIC designed in 130 nm SiGe BiCMOS technology for the upgrade of the pre-shower detector of the FASER experiment at CERN. The purpose of this prototype is to study the integration of fast front-end electronics inside the sensitive area of the pixels and to identify the configuration that could satisfy at best the specifications of the experiment. Self-induced noise, instabilities and cross-talk were minimised to cope with the several challenges associated to the integration of pre-amplifiers and discriminators inside the pixels. The methodology used in the characterisation and the design choices will also be described. Two of the variants studied here will be implemented in the pre-production ASIC of the FASER experiment pre-shower for further tests.

description: Este artigo tem como objetivo analisar a relação entre os jogos eletrônicos e a arte do Ukiyo-e a partir da série de gravuras Ukiyo-e Heroes, do impressor canadense David Bull e do desenhista norte-americano Jed Henry, na qual a tradição das gravuras japonesas incorpora elementos da cultura pop por meio de referências a personagens de jogos e de animes. Para o nosso estudo, utilizaremos do conceito de rizoma de Gilles Deleuze e Félix Guattari pensado como um meio de articulação de signos da cultura oriental e da ocidental, no instante em que, desterritorializados, eles se movimentam entre um passado e um presente cujas fronteiras se sobrepõem e das quais a redundância e a novidade convergem para a imagem, ao mesmo tempo, como diálogo e conflito entre o eu e o outro.

description: Do molecular clouds collapse to form stars at the same rate in all environments? In large spiral galaxies, the rate of transformation of H2 into stars (hereafter SFE) varies little. However, the SFE in distant objects (z~1) is much higher than in the large spiral disks that dominate the local universe. Some small local group galaxies share at least some of the characteristics of intermediate-redshift objects, such as size or color. Recent work has suggested that the Star Formation Efficiency (SFE, defined as the SFRate per unit H2) in local Dwarf galaxies may be as high as in the distant objects. A fundamental difficulty in these studies is the independent measure of the H2 mass in metal-deficient environments. At 490 kpc, NGC6822 is an excellent choice for this study; it has been mapped in the CO(2-1) line using the multibeam receiver HERA on the 30 meter IRAM telescope, yielding the largest sample of giant molecular clouds (GMCs) in this galaxy. Despite the much lower metallicity, we find no clear difference in the properties of the GMCs in NGC 6822 and those in the Milky Way except lower CO luminosities for a given mass. Several independent methods indicate that the total H2 mass in NGC 6822 is about 5 x 10^6 Msun in the area we mapped and less than 10^7 Msun in the whole galaxy. This corresponds to a NH2/ICO ~ 4 x 10^{21} cm^-2 /(Kkm/s) over large scales, such as would be observed in distant objects, and half that in individual GMCs. No evidence was found for H2 without CO emission. Our simulations of the radiative transfer in clouds are entirely compatible with these NH2/ICO values. The SFE implied is a factor 5 - 10 higher than what is observed in large local universe spirals.
