Pύπανση υδάτων

description: Εισαγωγή: Τα κυανοβακτήρια προσαρμόζονται εύκολα τόσο σε γλυκά όσο και σε αλμυρά υδάτινα περιβάλλοντα, σε παράκτιες περιοχές, σε καλλιέργειες, ακόμη και σε ξηρό έδαφος. Η αυξημένη ανάπτυξή τους στα υδάτινα οικοσυστήματα μπορεί να οδηγήσει σε διαταραχές αφενός στο περιβάλλον και αφετέρου στην ανθρώπινη υγεία. Οι κυανοτοξίνες που εκκρίνουν τα κυανοβακτήρια είναι πολλές φορές επιβλαβείς και απειλητικές για τη δημόσια υγεία. Σκοπός: Η παρούσα μελέτη αποσκοπεί στην ανάδειξη της σπουδαιότητας της πρόληψης και διαχείρισης της ανάπτυξης των κυανοβακτηρίων, προκειμένου να περιοριστούν οι επιβλαβείς επιπτώσεις της ανθρώπινης έκθεσης σε υψηλά επίπεδα κυανοτοξινών. Σημαντική είναι η διερεύνηση του ζητήματος ως ένα πρόβλημα της δημόσιας υγείας αλλά και της περιβαλλοντικής συνείδησης. Μεθοδολογία: Πραγματοποιήθηκε βιβλιογραφική ανασκόπηση, με αναζήτηση πρόσφατων και παλαιότερων δημοσιεύσεων που έχουν διερευνήσει το εν λόγω ζήτημα. Η ανασκόπηση στηρίχθηκε σε άρθρα δημοσιευμένα στην ελληνική και αγγλική γλώσσα από αναζήτηση σε βάσεις δεδομένων, όπως Pubmed και Google Scholar. Αποτελέσματα: Έχουν εντοπιστεί ορισμένα είδη κυανοβακτηρίων και κυανοτοξινών σε υδάτινα περιβάλλοντα τόσο θαλάσσιου όσο και γλυκού ύδατος, που μπορούν να προκαλέσουν αρνητικές ή και απειλητικές για την ανθρώπινη ζωή επιπτώσεις. Υπάρχουν επίσης κατευθυντήριες οδηγίες και κανονισμοί για τα συχνότερο εμφανιζόμενα κυανοβακτήρια, που οριοθετούν τις επιτρεπόμενες τιμές συγκέντρωσης των κυανοτοξινών στο πόσιμο νερό ή σε ύδατα αναψυχής. Συμπεράσματα: Η παρουσία και άνθιση των κυανοβακτηρίων στο υδάτινο περιβάλλον μπορεί να αποτελέσει κίνδυνο για τη δημόσια υγεία και το περιβάλλον. Απαιτούνται συνεχείς μελέτες για την εκτίμηση του επιπέδου συγκέντρωσης των κυανοτοξινών στα διάφορα υδάτινα περιβάλλοντα και η τήρηση των μέτρων πρόληψης και διαχείρισης του ρυθμού ανάπτυξης των κυανοβακτηρίων στα υδάτινα οικοσυστήματα τόσο στην Ελλάδα όσο και σε άλλες χώρες παγκοσμίως.
From the Search for the American Dream to the Journey Back to Southern Roots: Cinematic Representations of Black Migrations

description: African Americans are excluded from the myth of the ‘nation of immigrants’ due to the forced nature of their relocation to the American continent. Yet, this exclusion can engender an association of blackness with lack of mobility and agency in the national imaginary, which obscures historical constrictions produced by slavery, segregation, and racism. In the last years, new narratives, ranging from historiography to cultural productions, have emerged that highlight how black Americans, despite all odds, have always resorted to migration as a way to fight racism. Cinema has played a major role in the representation of African Americans’ migrations as a fight to become masters of their own lives and has influenced the current reclaiming of the South in important ways.

description: In this paper we attempt to answer to the question: can cosmic acceleration of the Universe have a fractal solution? We give an exact solution of a Lemaître-Tolman-Bondi (LTB) Universe based on the assumption that such a smooth metric is able to describe, on average, a fractal distribution of matter. While the LTB model has a center, we speculate that, when the fractal dimension is not very different from the space dimension, this metric applies to any point of the fractal structure when chosen as center so that, on average, there is not any special point or direction. We examine the observed magnitude-redshift relation of type Ia supernovae (SNe Ia), showing that the apparent acceleration of the cosmic expansion can be explained as a consequence of the fractal distribution of matter when the corresponding space-time metric is modeled as a smooth LTB one and if the fractal dimension on scales of a few hundreds Mpc is $D=2.9 \pm 0.02$.

description: Checking whether two pushdown automata with restricted silent actions are weakly bisimilar was shown decidable by Sénizergues (1998, 2005). We provide the first known complexity upper bound for this famous problem, in the equivalent setting of first-order grammars. This ACKERMANN upper bound is optimal, and we also show that strong bisimilarity is primitive-recursive when the number of states of the automata is fixed.

We present an extensive list of frequencies for the most common equations of state and some more recent ones. In order to check the accuracy, we use two different numerical schemes which yield the same results. The stimulation for this work comes from the need of the groups that evolve the full nonlinear Einstein equation to have reliable results from perturbation theory for comparison.

Subjects: promotional discourse; evaluation; appraisal theory; corpus linguistics; web communication

description: How do companies that produce highly diverse merchandise promote their different goods and how do they target them to their consumers? The Husqvarna brand is known for containing several divisions that manufacture a wide range of products from motorbikes to chainsaws and sewing machines. Each of these companies has its own dedicated webpage, which represents an important space for self-promotion and presentation of the characteristics of their products. However, while Husqvarna has been widely studied in terms of marketing and corporate social responsibility, whether the brand’s promotional strategies relative to the diverse products are more or less the same or change accordingly remains to be investigated. The present study sets out to fill this gap by examining how motorbikes and sewing machines are described and promoted on the respective Husqvarna websites by looking at branding, targeting, and promotional language. In order to carry out our analysis, we created two corpora from the official US Husqvarna Motorcycles and Sewing Machines websites. The two corpora have been analysed following both a quantitative and qualitative approach, combining corpus linguistics and appraisal theory (Martin and White 2005). This case study will yield insights on how multidivisional companies promote their different products and how they target them for their different audiences.

Shaping Stereotypes in a Space of Absence: A Linguistic Analysis of Wayne Wang’s “Chan Is Missing”
Creators: name: Renna, Dora
Publisher: name: Iperstoria
Year: 2021
Subjects: stereotypes; cinema; Systemic Functional Grammar; Critical Discourse Analysis; Asian American

description: Wayne Wang’s Chan Is Missing (1981) was acclaimed by the critics and broadly appreciated by the public for its innovative style and its lively depiction of San Francisco’s Chinatown. Academic discourse has focused on the film’s ability to embody the essence of Asian Americans (Tajima 1990), and on the challenges it poses to the common assumptions concerning this specific minority within the United States (Feng 1996). Indeed, the film is a milestone for cinema in general, and for the representation of Asians and Chinese Americans in particular, for it manages to be many different films at the same time. The aim of this paper is to use Systemic Functional Linguistics and Critical Discourse Analysis to investigate the linguistic image construction of Chan (whose name echoes the notorious Charlie Chan from the beginning of the 20th century) within the film. His identikit is (and at the same time fails to be) the outcome of a chorus of different voices. While the two protagonists, Jo and Steve, look for the missing Chan Hung, they talk to several people who have met him. Each character delivers a fragment of a shapeless portrait that does not help the protagonists finding him, actually causing even more confusion on his location and his identity. Each description has little to do with Chan himself, as it only represents the characters’ confrontation with the stereotypes attached to the Asian and Chinese American community. This attempt to use Chan as an image of what each character wants to detach from in order to define themselves is made possible and at the same time invalidated by his continuous absence, which represents the essence of the stereotype itself—only real in the words of the beholder.

description: Infrared (IR) hyperspectral imaging is a powerful approach in the field of materials and life sciences. However, for the extension to modern sub-diffraction nanoimaging it still remains a highly inefficient technique, as it acquires data via inherent sequential schemes. Here, we introduce the mathematical technique of low-rank matrix reconstruction to the sub-diffraction scheme of atomic force microscopy-based infrared spectroscopy (AFM-IR), for efficient hyperspectral IR nanoimaging. To demonstrate its application potential, we chose the trypanosomatid unicellular parasites Leishmania species as a realistic target of biological importance. The mid-IR spectral fingerprint window covering the spectral range from 1300 to 1900 cm−1 was chosen and a distance between the data points of 220 nm was used for nanoimaging of single parasites. The method of k-means cluster analysis was used for extracting the chemically distinct spatial locations. Subsequently, we randomly selected only 10% of an originally gathered data cube of 134 (x) × 50 (y) × 148 (spectral) AFM-IR measurements and completed the full data set by low-rank matrix reconstruction. This approach shows agreement in the cluster regions between full and reconstructed data cubes. Furthermore, we show that the results of the low-rank reconstruction are superior compared to alternative interpolation techniques in terms of error-metrics, cluster quality, and spectral interpretation for various subsampling ratios. We conclude that by using low-rank matrix reconstruction the data acquisition time can be reduced from more than 14 h to 1–2 h. These findings can significantly boost the practical applicability of hyperspectral nanoimaging in both academic and industrial settings involving nano- and bio-materials.
Pointing in Science: An Analysis of Body and Linguistic Deixis in Nobel Lectures with PowerPoint Slides
Creators: name: Cavalieri, Silvia
Publisher: name: Iperstoria
Year: 2021
Subjects: English linguistics; PowerPoint; Nobel lectures; spatial deixis; pointing

description: Within the last decades, PowerPoint has become a technology and a medium of communication that has contributed to a profound transformation of lecturing and presenting information in academia. However, until recently PowerPoint slideshows have received only limited attention in the fields of discourse analysis and social semiotic research (Djonov and Van Leeuwen 2011; 2012; 2013; Zhao, Djonov and Van Leeuwen 2014). Only a few studies have focused on the design of slideshows (e.g., Campagna 2009; Finn 2010; Rowley-Jolivet 2004) in relation to conference presentations (Degano 2012; Diani 2015; Costa 2017). Moreover, the interplay of speech, pointing, and body formations seems to have been neglected by the discourse analytical literature and has only been considered in the field of sociology (Knoblauch 2008). Pointing, nevertheless, seems to be a peculiar feature of conference presentations supported by PPT slides, allowing knowledge to be located in space. As a consequence, this paper aims to address aspects of linguistic pointing deixis in relation to the PowerPoint slides as well as to the body and gesture deixis of the presenter. To reach this aim, the study adopts a twofold methodology, fusing together Levinson’s theory of spatial deixis (1983) with the sociological approach of Knoblauch (2008) for body formation of pointing. The analysis is carried out on a corpus of nine Nobel lectures (i.e., three in economics; three in medicine; three in chemistry) collected from 2010 to 2015, considering their PowerPoints, their videos, and their transcriptions. Results show that knowledge transfer is defined in Nobel lecture PowerPoint presentations by the combination of speaking and showing, thus becoming presented knowledge rather than representing knowledge itself (Knoblauch 2008, 75).

description: This paper studies the application of cooperative techniques for non-orthogonal multiple access (NOMA). More particularly, the fixed gain amplify-and-forward (AF) relaying with NOMA is investigated over Nakagami-$m$ fading channels. Two scenarios are considered insightfully. 1) The first scenario is that the base station (BS) intends to communicate with multiple users through the assistance of AF relaying, where the direct links are existent between the BS and users; and 2) The second scenario is that the AF relaying is inexistent between the BS and users. To characterize the performance of the considered scenarios, new closed-form expressions for both exact and asymptomatic outage probabilities are derived. Based on the analytical results, the diversity orders achieved by the users are obtained. For the first and second scenarios, the diversity order for the $n$-th user are $μ(n+1)$ and $μn$, respectively. Simulation results unveil that NOMA is capable of outperforming orthogonal multiple access (OMA) in terms of outage probability and system throughput. It is also worth noting that NOMA can provide better fairness compared to conventional OMA. By comparing the two scenarios, cooperative NOMA scenario can provide better outage performance relative to the second scenario.

description: Using a deep Chandra AO-1 observation of the face-on spiral galaxy M101, we examine three of five previously optically-identified X-ray sources which are spatially correlated with optical supernova remnants (MF54, MF57, and MF83). The X-ray fluxes from these objects, if due to diffuse emission from the remnants, are bright enough to require a new class of objects, with the possible attribution by Wang to diffuse emission from hypernova remnants. Of the three, MF83 was considered the most likely candidate for such an object due to its size, nature, and close positional coincidence. However, we find that MF83 is clearly ruled out as a hypernova remnant by both its temporal variability and spectrum. The bright X-ray sources previously associated with MF54 and MF57 are seen by Chandra to be clearly offset from the optical positions of the supernova remnants by several arc seconds, confirming a result suggested by the previous work. MF54 does have a faint X-ray counterpart, however, with a luminosity and temperature consistent with a normal supernova remnant of its size. The most likely classifications of the sources are as X-ray binaries. Although counting statistics are limited, over the 0.3--5.0 keV spectral band the data are well fit by simple absorbed power laws with luminosities in the 10^38 to 10^39 ergs/s range. The power law indices are softer than those of Milky Way LMXB of similar luminosities, and are more consistent with those of the Large Magellanic Cloud. Both the high luminosity and the soft spectral shape favor these being accreting black hole binaries in high soft states.

description: Oxygen adsorption onto Ru (10 bar 1 0) results in the formation of two ordered overlayers, i.e. a c(2 times 4)-2O and a (2 times 1)pg-2O phase, which were analyzed by low-energy electron diffraction (LEED) and density functional theory (DFT) calculation. In addition, the vibrational properties of these overlayers were studied by high-resolution electron loss spectroscopy. In both phases, oxygen occupies the threefold coordinated hcp site along the densely packed rows on an otherwise unreconstructed surface, i.e. the O atoms are attached to two atoms in the first Ru layer Ru(1) and to one Ru atom in the second layer Ru(2), forming zigzag chains along the troughs. While in the low-coverage c(2 times 4)-O phase, the bond lengths of O to Ru(1) and Ru(2) are 2.08 A and 2.03 A, respectively, corresponding bond lengths in the high-coverage (2 times 1)-2O phase are 2.01 A and 2.04 A (LEED). Although the adsorption energy decreases by 220 meV with O coverage (DFT calculations), we observe experimentally a shortening of the Ru(1)-O bond length with O coverage. This effect could not be reconciled with the present DFT-GGA calculations. The nu(Ru-O) stretch mode is found at 67 meV [c(2 times 4)-2O] and 64 meV [(2 times 1)pg-2O].

description: We introduce a high-level graphical framework for designing and analysing quantum error correcting codes, centred on what we term the coherent parity check (CPC). The graphical formulation is based on the diagrammatic tools of the ZX-calculus of quantum observables. The resulting framework leads to a construction for stabilizer codes that allows us to design and verify a broad range of quantum codes based on classical ones, and that gives a means of discovering large classes of codes using both analytical and numerical methods. We focus in particular on the smaller codes that will be the first used by near-term devices. We show how CSS codes form a subset of CPC codes and, more generally, how to compute stabilizers for a CPC code. As an explicit example of this framework, we give a method for turning almost any pair of classical [n,k,3] codes into a [[2n-k+2,k,3]] CPC code. Further, we give a simple technique for machine search which yields thousands of potential codes, and demonstrate its operation for distance 3 and 5 codes. Finally, we use the graphical tools to demonstrate how Clifford computation can be performed within CPC codes. As our framework gives a new tool for constructing small- to medium-sized codes with relatively high code rates, it provides a new source for codes that could be suitable for emerging devices, while its ZX-calculus foundations enable natural integration of error correction with graphical compiler toolchains. It also provides a powerful framework for reasoning about all stabilizer quantum error correction codes of any size.

On Westerns and Settler Migration: A Reading of “Meek’s Cutoff” by Kelly Reichardt
Creators: name: Bordin, Elisa
Publisher: name: Iperstoria
Year: 2021
Subjects: Kelly Reichardt; Meek’s Cutoff; Oregon Trail; feminist revisionist western; migration

description: This essay examines Kelly Reichardt’s Meek’s Cutoff (2010) as an example of ‘slow’ and feminist western film. In particular, it shows how, by applying an “austere” aesthetics (Gorfinkel 2015) and by giving prominence to the act of migrating rather than the act of settling, the movie rewrites pioneer history, offering an example of what Catherine Russel defines “migrant cinema” (2017). Because of the visual centrality given to the act of migration, with its feeling of geographical displacement and psychological apprehension, the movie situates itself alongside other contemporary films representing present-day migration, and questions the traditional western movement as a travel of self-confident expansion and colonization. In this sense, Meek’s Cutoff can be rather read as a “decolonizing” (Trimble Young and Veracini 2017) rendition of white migration in the West, mostly achieved by including two destabilizing characters within the group of white settlers, Emily Tetherow and a Cayuse Indian, who trigger reflections on matters of knowledge and alliances.

Free vortex and vortex-pair lifetimes in classical two-dimensional easy-plane magnets

description: We report numerical simulation results for free-vortex lifetimes in the critical region of classical two-dimensional easy-plane ferro- and antiferromagnets having three-component order parameters. The fluctuations in the vortex number density in a spin dynamics simulation were used to estimate the lifetimes. The observed lifetimes are of the same order of magnitude but smaller than the characteristic time-scale above which a phenomenological ideal vortex-gas theory that has been used to account for the central peak in the dynamic structure factor $S^{αα}({\bf q},ω)$ is expected to be valid. % For strong anisotropy, where the vortices are in-plane, the free vortex lifetimes for ferromagnets and antiferromagnets are the same, while for weak anisotropy, where the vortices have nonzero out-of-easy-plane components, the lifetimes in antiferromagnets are smaller than in ferromagnets. The dependence of the free-vortex and total vortex densities on the size dependent correlation length in the critical region is examined. We also determined the lifetimes of vortex-antivortex pairs for $T = T_{\scriptsize KT}$ and well below $T_{\scriptsize KT}$. The observed time-scales are very short, and the observed pair densities are extremely small. These results suggest that pair creation and annihilation are unlikely to play any role in the central peak in $S^{xx}({\bf q},ω)$ observed in computer simulations for the ferromagnetic model for $T \leq T_{\scriptsize KT}$.

Displacing the American Dream in Mat Johnson’s “Drop”
Creators: name: Marino, Agnese
Publisher: name: Iperstoria
Year: 2021
Subjects: race studies; American dream; Mat Johnson; Foucault; heterotopia; Drop

description: Mat Johnson’s first work, Drop (2000), explores the themes of the American Dream and Nightmare in relation to issues of racial and national identity, racial inequality, and personal growth. The protagonist, a poor but talented African American man, decides to expatriate to England to chase the dream which he is denied at home. When his English Pygmalion dies, he is forced to return to the US and face the nightmare of racism, exclusion, and fear. However, he has also the chance to reconcile with his community, which will eventually help him leave the country again. This paper analyses Johnson’s use of the theme of expatriation in light of Michel Foucault’s concept of heterotopia and argues that, through heterotopia, the author is able to enact a decentring strategy which undermines national ideology and focuses on the active role played by the Black community in its members’ self-improvement.

description: We calculate the mean density profiles for luminous and dark matter on distance scales $D \sim(1 - 100)$ Mpc around us using recent all-sky catalogs of galaxy groups. Within the Local Volume $( D < 11 ~\rm Mpc)$ we derived the mean stellar density $Ω_*= 0.44\%$ in the critical density units and the mean total matter density $Ω_m = 0.17$. In the sphere with a radius of 40 Mpc these quantities drop to $Ω_* = 0.24 - 0.32\%$ and $Ω_m = 0.09 - 0.14$. In a larger volume within $D\sim135$ Mpc the discussed densities become more uncertain: $Ω_* = 0.20 - 0.24\%$ and $Ω_m = 0.05 - 0.16$. We summarize that the major part of the cosmic dark matter locates outside the virial and collapsing zones of groups and clusters.

On ‘Not Being Nothing’: Post-ironic Melodrama in James Gray’s “The Immigrant”
Creators: name: Francescato, Simone
Publisher: name: Iperstoria
Year: 2021
Subjects: James Gray; The Immigrant; migration cinema; post-irony; melodrama

description: This essay analyzes James Gray’s The Immigrant (2013) discussing it as an instance of post-ironic melodrama (Włodek 2017) aimed at recovering the purity shown by this genre in the early phases of cinematic history. The essay argues that, although the movie pays evident homage to pre-classic silent-era melodramas, it also destabilizes the genre’s conventions by resorting to a particular use of the mise-en-scène and characterization. This directorial choice allows the film to retain pathos without eschewing ambivalence and indeterminacy, finally contributing to produce a complex representation of immigrants’ experience as well as a rather bleak portrait of the American Dream.

description: We present the results from ALMA CO(3-2) observations of 66 Halpha-selected galaxies in three protoclusters around radio galaxies, PKS1138-262 (z=2.16) and USS1558-003 (z=2.53), and 4C23.56 (z=2.49). The pointing areas have an overdensity of ~100 compared to a mean surface number density of galaxies in field environments. We detect CO emission line in 16 star-forming galaxies, including previously published six galaxies, to measure the molecular gas mass. In the stellar mass range of 10.511.0 are comparable in mass to the scaling relation, or smaller. Our results suggest that the environmental effects on gas properties are mass-dependent: in high-density environments, gas accretion through cosmic filaments is accelerated in less massive galaxies while this is suppressed in the most massive system.

description: We prove that maximum a posteriori estimators are well-defined for diagonal Gaussian priors ,u on tp under common assumptions on the potential F. Further, we show connections to the Onsager-Machlup functional and provide a corrected and strongly simplified proof in the Hilbert space case p= 2, previously established by Dashti et al (2013 Inverse Problems 29 095017); Kretschmann (2019 PhD Thesis). These corrections do not generalize to the setting 1 ? p < 8, which requires a novel convexification result for the difference between the Cameron-Martin norm and the p-norm.

description: Criticality in a fluid of dielectric constant D that exhibits Ising-type behavior is studied as additional electrostatic (i.e., ionic) interactions are turned on. An exploratory perturbative calculation is performed for small ionicity as measured by the ratio of the electrostatic energy to the strength of the short-range nonionic (i.e., van der Waals) interactions in the uncharged fluid. With the aid of distinct transformations for the short-range and for the Coulombic interactions, an effective Hamiltonian with coefficients depending on the ionicity is derived at the Debye-Hueckel limiting-law level for a fully symmetric model. The crossover between classical (mean-field) and Ising behavior is then estimated using a Ginzburg criterion. This indicates that the reduced crossover temperature depends only weakly on the ionicity (and on the range of the nonionic potentials); however, the trends do correlate with the, much stronger, dependence observed experimentally.

description: Collective motion is commonly modeled with static interaction rules between agents. Substantial empirical evidence indicates, however, that animals may adapt their interaction rules depending on a variety of factors and social contexts. Here, we hypothesized that leadership performance is linked to the leader's responsiveness to the follower's actions and we predicted that a leader is followed longer if it adapts to the follower's avoidance movements. We tested this prediction with live guppies that interacted with a biomimetic robotic fish programmed to act as a 'socially competent' leader. Fish that were avoiding the robot were approached more carefully in future approaches. In two separate experiments we then asked how the leadership performance of the socially competent robot leader differed to that of a robot leader that either approached all fish in the same, non-responsive, way or one that did change its approach behavior randomly, irrespective of the fish's actions. We found that (1) behavioral variability itself appears attractive and that socially competent robots are better leaders which (2) require fewer approach attempts to (3) elicit longer average following behavior than non-competent agents. This work provides evidence that social responsiveness to avoidance reactions plays a role in the social dynamics of guppies. We showcase how social responsiveness can be modeled and tested directly embedded in a living animal model using adaptive, interactive robots.

description: Crash prediction is a critical component of road safety analyses. A widely adopted approach to crash prediction is application of regression based techniques. The underlying calibration process is often time-consuming, requiring significant domain knowledge and expertise and cannot be easily automated. This paper introduces a new machine learning (ML) based approach as an alternative to the traditional techniques. The proposed ML model is called regularized deep belief network, which is a deep neural network with two training steps: it is first trained using an unsupervised learning algorithm and then fine-tuned by initializing a Bayesian neural network with the trained weights from the first step. The resulting model is expected to have improved prediction power and reduced need for the time-consuming human intervention. In this paper, we attempt to demonstrate the potential of this new model for crash prediction through two case studies including a collision data set from 800 km stretch of Highway 401 and other highways in Ontario, Canada. Our intention is to show the performance of this ML approach in comparison to various traditional models including negative binomial (NB) model, kernel regression (KR), and Bayesian neural network (Bayesian NN). We also attempt to address other related issues such as effect of training data size and training parameters.

description: The ability to support metastable current-carrying states in multiply-connected settings is one of the prime signatures of superfluidity. Such states are investigated theoretically for the case of trapped Bose condensed alkali gases, particularly with regard to the rate at which they decay via thermal fluctuations. The lifetimes of metastable currents can be either longer or shorter than experimental time-scales. A scheme for the experimental detection of metastable states is sketched.
