description: The dispersion of the volume relativistic magnetoplasma mode in a gated GaAs/AlGaAs quantum well is measured using a coupled resonators detection technique. The weakly damped relativistic mode exhibits an unusual zigzag-shaped magnetodispersion dependence dictated by the diagonal component of the resistivity tensor $ρ_{xx}$. The plasma excitation easily hybridizes with photon modes due to a large spatial delocalization of its electromagnetic field. The effects of electron density and structure geometry on the excitation spectrum have been investigated.

description: A leg length difference can arise in different ways. This leg length difference can then lead to deviations in gait. The scientific literature does not answer why a leg length difference of a minimum of 7 centimeters is a prerequisite for participation in the Paralympic Games. Therefore, our scoping review intends to synthesize evidence on the different levels of leg length discrepancy on gait to answer the following research question: What is the effect of the extent of a leg length difference on gait? This study is part of a project on the classification of the amputation level for participating in paralympic sports.
Gender equality in education: bridging the gap between international goals and national realities
Creators: name: Dalyot, Keren
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2012

description: Gender equality in education is a principle acknowledged by the international community, however for a long time it was promoted as a legal obligation or political commitment. Progresses in the international arena have been achieved, but are international rights and goals sufficient? Post conflict situations require a broader perception of gender equality and inequality because of the interplay between gender and violent conflict. This is often a neglected context in international goal setting. Gender equality is fundamental but we need to think strategically and contextually about aid programs and policy development in order to affect long term social change. Nussbaum's capabilities approach offers a unique approach that can help bridge the gap between universal goals and values and local contexts and experiences of girls. There needs to be a moral commitment to gender equality in education, in addition to the political or legal commitment.

description: For a cyclic covering map $(Σ,K) \to (Σ',K')$ between two pairs of a 3-manifold and a knot each, we describe the fundamental group $π_1(Σ\setminus K)$ in terms of $π_1(Σ' \setminus K')$. As a consequence, we give an alternative proof for the fact that certain knots in $S^3$ cannot be represented as the preimage of any knot in a lens space, which is related to free periods of knots. In our proofs, the subgroup of a group $G$ generated by the commutators and the $p$th power of each element of $G$ plays a key role.

Die Mobilisierung des Privaten

description: Matilda Felix Mobilising Privateness Taking the example of the commercial art produced by Delaware, a Japanese art collective, this paper illustrates how applications for mobile phone displays reminiscent of embroidery patterns express a paradoxical reference to privateness: whereas the mobile phone stands for the location-independence of contemporary subjects, that is, an apparently gained freedom and autonomy, it serves precisely to locate individuals in everyday life. As the paper shows, the use of mobile phones even strengthens the traditional Japanese family model, in that it enables mothers to have permanent contact with other family members and thus changes nothing about traditional allocations of roles and space. Delaware’s digital embroidery applications redouble and intensify this paradoxical perpetuation of the status quo in that their hybridisation of digital and manual technology, advanced graphics and traditional motifs, helps create an image free of contradiction.

Are globular clusters the natural outcome of regular high-redshift star formation?

Subjects: subject: Astrophysics of Galaxies (astro-ph.GA)
subject: FOS: Physical sciences

description: We summarise some of the recent progress in understanding the formation and evolution of globular clusters (GCs) in the context of galaxy formation and evolution. It is discussed that an end-to-end model for GC formation and evolution should capture four different phases: (1) star and cluster formation in the high-pressure interstellar medium of high-redshift galaxies, (2) cluster disruption by tidal shocks in the gas-rich host galaxy disc, (3) cluster migration into the galaxy halo, and (4) the final evaporation-dominated evolution of GCs until the present day. Previous models have mainly focussed on phase 4. We present and discuss a simple model that includes each of these four steps - its key difference with respect to previous work is the simultaneous addition of the high-redshift formation and early evolution of young GCs, as well as their migration into galaxy haloes. The new model provides an excellent match to the observed GC mass spectrum and specific frequency, as well as the relations of GCs to the host dark matter halo mass and supermassive black hole mass. These results show (1) that the properties of present-day GCs are reproduced by assuming that they are the natural outcome of regular high-redshift star formation (i.e. they form according to same physical processes that govern massive cluster formation in the local Universe), and (2) that models only including GC evaporation strongly underestimate their integrated mass loss over a Hubble time.

Weissia controversa

description: Weissia controversa Hedw. Sp. Musc. Frond. 67. 1801 (Hedwig 1801).
Type:—Lipsiae ad rivulum post collem Bienitz. Humo theca loca, nec non sabulosa, uda, praeprimis regionum montosarum amat (lectotype designated here, Tab. 5. B. in Hedwig 1791 –1792).
 Typification notes:—The genus Weissia Hedw. was typified on W. controversa Hedw. by Mitten (1856). When W. controversa was proposed by Hedwig (1801), he used the validating descriptions and illustrations which he had previously given to the same species (Hedwig 1791 –1792). Although there was no designation of the holotype in either publication (Hedwig 1791 –1792, 1801), in the plotologue (Hedwig 1801) he referred to a specimen from Leipzig. One specimen from Leipzig, named W. controversa in Hedwig’s herbarium (G; Supplemental Information Fig. S.1), is the best candidate for a lectotype. In his taxonomic revision of Weissia for the Iberian Peninsula, Guerra (2002) selected this specimen as a lectotype for W. controversa. However, he did not include the phrase “designated here” or an equivalent, thus making this an ineffective typification (ICN Art. 7.10). This specimen has unfortunately been lost while on loan (Price 2005, p. 378). Hedwig’s illustration (Hedwig 1971–1792, Tab. 5. B.) is from the original material and is considered to be the only element that certainly fits Hedwig’s concept of the species, being the safest choice as lectotype. Hedwig (1791 –1792, 1801) cited Vaillant’s and Dillenius’ pre-Linnean phrase-names with reference to their illustrations under W. controversa as synonyms. Vaillant (1727) and Dillenius (1742) did not refer to any particular specimen and made only general comment on habitat information. These two illustrations given by Vaillant and Dillenius can be considered parts of original material, but we believe that the Hedwig’s illustration provides much more morphological information and is therefore better to select this as the lectotype.
 To ensure nomenclatural stability a specimen from the type locality, Bienitz in Leipzig, with DNA information should be selected as the epitype supporting the lectotype illustration rather than selecting an old specimen without DNA information, because the modern concept of W. controversa is thought to be polyphyletic (Werner et al. 2005, and present study) and a morpho-molecular revision is necessary to provide a better circumscription of the species.

description: Just as string T-duality originates from transforming field equations into Bianchi identities on the string worldsheet, so it has been suggested that M-theory U-dualities originate from transforming field equations into Bianchi identities on the membrane worldvolume. However, this encounters a problem unless the target space has dimension $D = p + 1$. We identify the problem to be the nonintegrability of the U-duality transformation assigned to the pull-back map. Just as a double geometry renders manifest the $O(D,D)$ string T-duality, here we show in the case of the M2-brane in $D = 3$ that a generalised geometry renders manifest the $SL(3) \times SL(2)$ U-duality. In the case of M2-brane in $D=4$, with and without extra target space coordinates, we show that only the ${\rm GL}(4,R)\ltimes R^4$ subgroup of the expected $SL(5,R)$ U-duality symmetry is realised.

description: SIGRID ADORF, JENNIFER JOHN The Private Remains Political: Concepts of Subjectivity Symptomatic of the Present (Introduction) This issue addresses one of the central claims of feminist discourse of the 1970s, namely, that “The private is political.” Starting from the significance of this insight during that historical period, contributors to the present issue explore whether and, if so, how this idea might be reformulated in 2010, as well as linked to Foucault’s concept of governmentality. They thus take up the calls issued in the previous issue, Kanones (No. 48), for rendering fruitful feminist insights gained during recent decades for contemporary discourse. Does it make any sense, in an age characterised increasingly by the blending of work and leisure and the related debate on precarisation, to return to the modern concept of “public versus private”? And if such a return does make sense, then on which premises? What is political about displaying privateness? How do artists engage with the current stagings of privateness? And which other connections relevant to cultural analysis can be established with other prominent discourses within the debate on aesthetics?

description: As a promising architectural design for future Internet, named data networking (NDN) relies on in-network caching to efficiently deliver name-based content. However, the in-network caching is vulnerable to cache pollution attacks (CPA), which can reduce cache hits by violating cache locality and significantly degrade the overall performance of NDN. To defend against CPA attacks, the most effective way is to first detect the attacks and then throttle them. Since the CPA attack itself has already imposed a huge burden on victims, to avoid exhausting the remaining resources on the victims for detection purpose, we expect a lightweight detection solution. We thus propose ELDA, an Efficient and Lightweight Detection scheme against cache pollution Attacks, in which we design a Lightweight Flajolet-Martin (LFM) sketch to monitor the interest traffic. Our analysis and simulations demonstrate that, by consuming a few computation and memory resources, ELDA can effectively and efficiently detect CPA attacks.

description: Doris Berger Differences on Screen: How Gender Plays Out in Biopics about Women Artists Representations of artists in biographical movies are highly gendered. After the film genre of biopics is presented, crucial elements that influence biopics next to their biographical content are in focus, such as artist myths related to art history and star legends related to the film industry. With these parameters in mind, gendered elements of biopics are described, highlighting recurring narratives and representations in films about women artists. Different depictions of the suffering of male and female artists, or a narrative that understands motherhood and creativity as incompatible are focused on. Finally, the recent biopic Séraphine (Martin Provost, 2008), which tells the story about the relationship between the painter Séraphine de Senlis and the art dealer Wilhelm Uhde, is evaluated for its mostly conscious approach to the film genre.

description: We consider a set of density matrices. All of which are written in the same orbital basis, but the orbital basis size is less than the total Hilbert space size. We ask how each density matrix is related to each of the others by establishing a norm between density matrices based on the truncation error in a partial trace for a small set of orbitals. We find that states with large energy differences must have large differences in their density matrices. Small energy differences are divided into two groups, one where two density matrices have small differences and another where they are very different, as is the case of symmetry. We extend these ideas to a bundle of matrix product states and show that bond dimension of the wavefunction ansatz for two states with large energy differences are larger. Meanwhile, low energy differences can have nearly the same bond dimensions for similar states.

description: Isabell Lorey Virtuosity between Servility and Exodus. The Postfordist Public, Social Production, and Political Action In what fundamental ways is the present relationship between the public, work, and intellect changing – the Aristotelian three-way partition of social praxis, which figures mainly in the work of Hanna Arendt? What is the function of the creative work in these postfordist transformations? On this question, Pablo Virno has delivered inspiring deliberations with his concept of virtuosity. But he has not extended his inquiry into a current postfordian and governmental idea of freedom. Not only in the example of contribution of culture producers does to the precariousness of their own existence does this freedom mean obedience and servility. But how can one escape this servile virtuosity? And how would political action become conceivable?

description: K2 space observations recently found that three super-Earths transit the nearby M dwarf K2-3. The apparent brightness and the small physical radius of their host star rank these planets amongst the most favourable for follow-up characterisations. The outer planet orbits close to the inner edge of the habitable zone and might become one of the first exoplanets searched for biomarkers using transmission spectroscopy. We used the HARPS velocimeter to measure the mass of the planets. The mass of planet $b$ is $8.4\pm2.1$ M$_\oplus$, while our determination of those planets $c$ and $d$ are affected by the stellar activity. With a density of $4.32^{+2.0}_{-0.76}$ $\mathrm{g\;cm^{-3}}$, planet $b$ is probably mostly rocky, but it could contain up to 50% water.

description: We discuss the detectability of large-scale HI intensity fluctuations using the FAST telescope. We present forecasts for the accuracy of measuring the Baryonic Acoustic Oscillations and constraining the properties of dark energy. The FAST $19$-beam L-band receivers ($1.05$--$1.45$ GHz) can provide constraints on the matter power spectrum and dark energy equation of state parameters ($w_{0},w_{a}$) that are comparable to the BINGO and CHIME experiments. For one year of integration time we find that the optimal survey area is $6000\,{\rm deg}^2$. However, observing with larger frequency coverage at higher redshift ($0.95$--$1.35$ GHz) improves the projected errorbars on the HI power spectrum by more than $2~σ$ confidence level. The combined constraints from FAST, CHIME, BINGO and Planck CMB observations can provide reliable, stringent constraints on the dark energy equation of state.

Protein in-cell NMR in Escherichia coli

description: The inside of the cell is a crowded and complex environment that is impossible to duplicate by studying proteins and other molecules in dilute solution. The effects of macromolecular crowding are potentially important to all cellular functions, but until recently studies have been conducted mostly in dilute solution. In-cell Nuclear Magnetic Resonance (NMR) spectroscopy is becoming an important tool in studying proteins under physiologically relevant conditions. In some instances, however, protein signals from leaked protein are seen in the supernatant surrounding the in-cell slurry. I examined how expression levels contribute to protein leakage. I also describe a device and system that provides a controlled environment for NMR experiments in living cells. I have utilized this device to study the expression of the natively disordered protein - synuclein, inside Escherichia coli. In the future, we hope to make progress in using this device to study proteins in eukaryotic cells with NMR.
THE IMPACT OF PHYSICAL FITNESS AND PHYSICAL ACTIVITY LEVEL ON BIOMECHANICAL AND METABOLIC PARAMETERS OF TREADMILL WALKING IN NORMAL-WEIGHT AND OBESE YOUNG ADULTS.

description: Obesity and physical inactivity are classified as ?noncommunicable disease? and causes every year millions of deaths in the world. Walking has been proposed as a valid way to fight against these diseases because it can produce substantial health benefits and also because people can easily perform it every day. AIMS: At first, we assessed if physical activity (PA) or physical fitness (PF) could affect walking economy (Net EC) and efficiency in a group of healthy normal-weight adults, separately for men and women. Secondly, we assessed the same variables in a group of obese young adults. MATERIALS AND METHODS: 30 young normal-weight (14F,16M; 18.530 kg?m-2) subjects were recruited in the study. Economy (Net EC) was analyzed with indirect calorimetry and, simultaneously, total mechanical work (Wtot) was assessed with an optoelectronic system at 3.5/ 4.5/ 5.5 km?h-1. Efficiency was calculated as Wtot/Net EC. To assess PA, subjects wore an activity monitor for a whole week, inferring time spent in sedentary (SED, <1.5 METs), or moderate to vigorous (MVPA, >3 METs) physical activity. MVPA were calculated both as overall daily minutes (MVPAall) and also in bouts of at least 10 min (MVPAbouts). To assess PF, a maximal V?O2max test was performed on a treadmill with indirect calorimetry, isometric maximal voluntary contraction (iMVC) of lower limbs was measured by two force plates on horizontal leg press, flexibility (Flex) was assessed by the V-sit and reach test, and % fat mass (%FM) was evaluated with skinfold thickness (in normal-weight) or with girth measurements (in obese subjects). RESULTS: In normal-weight adults, no significant associations, adjusted for age and body mass index, were identified between PA and gait economy or efficiency. Regarding PF, in females iMVC and Flex affected efficiency (R2 = 0.73, F= 12.95, p<0.001), whereas V?O2max and iMVC were associated with economy (R2 = 0.69, F= 15.13, p<0.001). In the obese group, at a speed near the preferred one, SED (with %FM, iMVC and Flex) was positively associated with Net EC (R2 = 0.54, F= 4.04, p<0.05), whereas MVPAall was positively associated with gait efficiency (R2 = 0.32, F= 4.09, p<0.05). CONCLUSIONS: The main findings of this study were that in normal-weight adults PA did not affect neither economy nor efficiency of treadmill walking, whereas in obese individuals SED reduced gait economy and MVPAall enhanced gait efficiency. These findings might to be considered for exercise prescription.

description: The debate about how antimatter or different antimatter systems behave gravitationally will be ultimately decided by experiments measuring directly the acceleration of various antimatter probes in the gravitational field of the Earth or perhaps redshift effects in antimatter atoms caused by the annual variation of the Sun's gravitational potential at the location of the Earth. Muonium atoms may be used to probe the gravitational interaction of leptonic, second generation antimatter. We discuss the progress of our work towards enabling such experiments with muonium.

description: Modern TOF-PET scanner systems require high-speed computing resources for efficient data processing, monitoring and image reconstruction. In this article we present the data flow and software architecture for the novel TOF-PET scanner developed by the J-PET collaboration. We discuss the data acquisition system, reconstruction framework and image reconstruction software. Also, the concept of computing outside hospitals in the remote centers such as Świerk Computing Centre in Poland is presented.

description: Mergers of gas-rich galaxies are key events in the hierarchical built-up of cosmic structures, and can lead to the formation of massive black hole binaries. By means of high-resolution hydrodynamical simulations we consider the late stages of a gas-rich major merger, detailing the dynamics of two circumnuclear discs, and of the hosted massive black holes during their pairing phase. During the merger gas clumps with masses of a fraction of the black hole mass form because of fragmentation. Such high-density gas is very effective in forming stars, and the most massive clumps can substantially perturb the black hole orbits. After $\sim 10$ Myr from the start of the merger a gravitationally bound black hole binary forms at a separation of a few parsecs, and soon after, the separation falls below our resolution limit of $0.39$ pc. At the time of binary formation the original discs are almost completely disrupted because of SNa feedback, while on pc scales the residual gas settles in a circumbinary disc with mass $\sim 10^5 M_\odot$. We also test that binary dynamics is robust against the details of the SNa feedback employed in the simulations, while gas dynamics is not. We finally highlight the importance of the SNa time-scale on our results.

An American Encounter with Polystylism: Schnittke's Cadenzas to Beethoven
Creators: name: Rapaport, Aaron
Publisher: name: University of North Carolina at Chapel Hill
Year: 2012

description: This thesis explores the early reception of Alfred Schnittke in America. Writers on Schnittke's music have continually focused on the most distinct development of his compositional practice: polystylism. However, considerations of polystylism as a method for obtaining compositional coherence have hitherto been few. This thesis examines Schnittke's 1977 cadenzas to Beethoven's Violin Concerto because they are some of the earliest pieces that brought Schnittke to American attention from critics who felt that the cadenzas were inappropriate to the Concerto. The importance of these cadenzas as America's introduction to the composer has not yet been discussed. Furthermore, an analysis based on interpretations of the musical logic of Charles Ives's quotations suggests that Schnittke's motivic integration and compositional structure in the cadenzas demonstrate modern (nineteenth-century) musical concerns, resulting in a unified composition that adheres to the forms of traditional cadenzas.

description: The orthorhombic molybdenum carbide superconductor with $T_c$ = 3.2 K was investigated by muon-spin rotation and relaxation ($μ$SR) measurements and by first-principle calculations. The low-temperature superfluid density, determined by transverse-field $μ$SR, suggests a fully-gapped superconducting state in Mo$_2$C, with a zero-temperature gap $Δ_0$ = 0.44 meV and a magnetic penetration depth $λ_0$ = 291 nm. The time-reversal symmetry is preserved in the superconducting state, as confirmed by the absence of an additional muon-spin relaxation in the zero-field $μ$SR spectra. Band-structure calculations indicate that the density of states at the Fermi level is dominated by the Mo $4d$-orbitals, which are marginally hybridized with the C $2p$-orbitals over a wide energy range. The symmetry analysis confirms that, in the absence of spin-orbit coupling (SOC), Mo$_2$C hosts twofold-degenerate nodal surfaces and fourfold-degenerate nodal lines. When considering SOC, the fourfold-degenerate nodal lines cross the Fermi level and contribute to the electronic properties. Our results suggest that, similarly to other phases of carbides, also the orthorhombic transition-metal carbides host topological nodal states and may be potential candidates for future studies of topological superconductivity.

description: What Do We Stand? Since its inception, feminist art history has developed theories of the pictorial and, wisely, never a picture theory The article critically evaluates recent research focusing on “the” image. While feminist art history has argued that images need to be located historically, socially, and culturally, picture theory acts on the assumption of an essential core to “the” image. By way of this ontologically driven perception, feminist and queer perspectives are forcefully suppressed. Werner argues for a reevaluation of the important intellectual achievements of feminist art history and for the strategic reworking of traditional canons.

description: A cluster variety of Fock and Goncharov is a scheme constructed by gluing split algebraic tori, called seed tori, via birational gluing maps called mutations. In quantum theory, the ring of functions on seed tori are deformed to non-commutative rings, represented as operators on Hilbert spaces. Mutations are quantized to unitary maps between the Hilbert spaces intertwining the representations. These unitary intertwiners are described using the quantum dilogarithm function $Φ^\hbar$. Algebraic relations among classical mutations are satisfied by the intertwiners up to complex constants. The present paper shows that these constants are $1$. So the mapping class group representations resulting from the Chekhov-Fock-Goncharov quantum Teichmüller theory are genuine, not projective. During the course, the hexagon and the octagon operator identities for $Φ^\hbar$ are derived.
description: 38 pages; shortened version of arXiv:1602.00361 prepared for journal submission; this ver3 is substantially revised and improved, with the previously conjectural hexagon and the octagon identities proved
Arctic Plant Migration by 2100: Comparing Predictions with Observations
Creators: name: Winters, Dahl

Year: 2009

description: Nowhere are the consequences of climate change greater than in the Arctic. The Arctic Climate Impact Assessment synthesized the potential impacts of climate change to Arctic ecosystems, including vegetation changes projected for 2100 using the BIOME4 dynamic vegetation model. In my research I synthesized empirical data from 30 studies of Arctic vegetation responses to climate change, and compared these data to the ACIA projected vegetation distribution for 2100. A general agreement between observed and projected changes was found, with exceptions due to regional variability and geographic clustering of the empirical data. There exist large areas of Siberia east of the Taymyr Peninsula and the Arctic Peninsula without empirical data, but are projected to undergo expansive change. Likewise, geographically limited empirical data have been published for large areas with no projected change in central Siberia and in the Yukon and Northwest Territories, Canada.

description: Big data has now become a strong focus of global interest that is increasingly attracting the attention of academia, industry, government and other organizations. Big data can be situated in the disciplinary area of traditional geospatial data handling theory and methods. The increasing volume and varying format of collected geospatial big data presents challenges in storing, managing, processing, analyzing, visualizing and verifying the quality of data. This has implications for the quality of decisions made with big data. Consequently, this position paper of the International Society for Photogrammetry and Remote Sensing (ISPRS) Technical Commission II (TC II) revisits the existing geospatial data handling methods and theories to determine if they are still capable of handling emerging geospatial big data. Further, the paper synthesises problems, major issues and challenges with current developments as well as recommending what needs to be developed further in the near future.

description: We present a comprehensive catalog and analysis of broad-band afterglow observations for 103 short-duration gamma-ray bursts (GRBs), comprised of all short GRBs from November 2004 to March 2015 with prompt follow-up observations in the X-ray, optical, near-infrared and/or radio bands. These afterglow observations have uncovered 71 X-ray detections, 30 optical/NIR detections, and 4 radio detections. Employing the standard afterglow synchrotron model, we perform joint probability analyses for a subset of 38 short GRBs with well-sampled light curves to infer the burst isotropic-equivalent energies and circumburst densities. For this subset, we find median isotropic-equivalent gamma-ray and kinetic energies of E_gamma,iso~2x10^51 erg, and E_K,iso~(1-3)x10^51 erg, respectively, depending on the values of the model input parameters. We further find that short GRBs occur in low-density environments, with a median density of n~(3-15)x10^-3 cm^-3, and that ~80-95% of bursts have densities of less than 1 cm^-3. We investigate trends between the circumburst densities and host galaxy properties, and find that events located at large projected offsets of >10 effective radii from their hosts exhibit particularly low densities of n<10^-4 cm^-3, consistent with an IGM-like environment. Using late-time afterglow data for 11 events, we find a median jet opening angle of theta_jet=16+/-10 deg. We also calculate a median beaming factor of f_b~0.04, leading to a beaming-corrected total energy release of E_true~1.6x10^50 erg. Furthermore, we calculate a beaming-corrected event rate of R_true=270 (+1580,-180) Gpc^-3 yr^-1, or ~8 (+47,-5) yr^-1 within a 200 Mpc volume, the Advanced LIGO/Virgo typical detection distance for NS-NS binaries.

description: Angelika Bartl Angelika Bartl: The Reflexive Smile of the Other. Feminist Art Criticism, Documentary Video Art, and the Question of the Political Having itself become canonical in the past few decades, feminist art critique may run the risk of essentializing its own notion of feminist politics. The article shows how dealing with new documentary video art representing marginalized women (in this case the video essay “operculum” [1993] by Tran T. Kim-Trang) confronts us with a complexity of political discourses – feminist, postcolonial, anti-capitalist, etc. – that question our desire for essential meanings and assignments.

Rationality, universal generation and the integral Hodge conjecture

description: We use the universal generation of algebraic cycles to relate (stable) rationality to the integral Hodge conjecture. We show that the Chow group of 1-cycles on a cubic hypersurface is universally generated by lines. Applications are mainly in cubic hypersurfaces of low dimensions. For example, we show that if a generic cubic fourfold is stably rational then the Beauville--Bogomolov form on its variety of lines, viewed as an integral Hodge class on the self product of its variety of lines, is algebraic. In dimension $3$ and $5$, we relate stable rationality with the geometry of the associated intermediate Jacobian.
