description: In this paper we present a construction for the compact form of the exceptional Lie group E6 by exponentiating the corresponding Lie algebra e6, which we realize as the the sum of f4, the derivations of the exceptional Jordan algebra J3 of dimension 3 with octonionic entries, and the right multiplication by the elements of J3 with vanishing trace. Our parametrization is a generalization of the Euler angles for SU(2) and it is based on the fibration of E6 via a F4 subgroup as the fiber. It makes use of a similar construction we have performed in a previous article for F4. An interesting first application of these results lies in the fact that we are able to determine an explicit expression for the Haar invariant measure on the E6 group manifold.

description: The simple $m^2ϕ^2$ potential as an inflationary model is coming under increasing tension with limits on the tensor-to-scalar ratio $r$ and measurements of the scalar spectral index $n_s$. Cubic Galileon interactions in the context of the Horndeski action can potentially reconcile the observables. However, we show that this cannot be achieved with only a constant Galileon mass scale because the interactions turn off too slowly, leading also to gradient instabilities after inflation ends. Allowing for a more rapid transition can reconcile the observables but moderately breaks the slow-roll approximation leading to a relatively large and negative running of the tilt $α_s$ that can be of order $n_s-1$. We show that the observables on CMB and large scale structure scales can be predicted accurately using the optimized slow-roll approach instead of the traditional slow-roll expansion. Upper limits on $|α_s|$ place a lower bound of $r\gtrsim 0.005$ and conversely a given $r$ places a lower bound on $|α_s|$, both of which are potentially observable with next generation CMB and large scale structure surveys.

description: We demonstrate the injection and transport of spin-polarized electrons through n-type doped silicon with in-plane spin-valve and perpendicular magnetic field spin precession and dephasing ("Hanle effect") measurements. A voltage applied across the transport layer is used to vary the confinement potential caused by conduction band-bending and control the dominant transport mechanism between drift and diffusion. By modeling transport in this device with a Monte-Carlo scheme, we simulate the observed spin polarization and Hanle features, showing that the average transit time across the short Si transport layer can be controlled over 4 orders of magnitude with applied voltage. As a result, this modeling allows inference of a long electron spin lifetime, despite the short transit length.

description: Background: Since the invention of next-generation RNA sequencing (RNA-seq) technologies, they have become a powerful tool to study the presence and quantity of RNA molecules in biological samples and have revolutionized transcriptomic studies. The analysis of RNA-seq data at four different levels (samples, genes, transcripts, and exons) involve multiple statistical and computational questions, some of which remain challenging up to date. Results: We review RNA-seq analysis tools at the sample, gene, transcript, and exon levels from a statistical perspective. We also highlight the biological and statistical questions of most practical considerations. Conclusion: The development of statistical and computational methods for analyzing RNA- seq data has made significant advances in the past decade. However, methods developed to answer the same biological question often rely on diverse statical models and exhibit different performance under different scenarios. This review discusses and compares multiple commonly used statistical models regarding their assumptions, in the hope of helping users select appropriate methods as needed, as well as assisting developers for future method development.
Dark Filaments in the Galaxy NGC 253 - a Boiling Galactic Disk -

description: We study the morphology of dark lanes and filaments in the dust-rich galaxy NGC 253 using an unsharp-masked $B$-band optical photograph. Dust features are classified as `arcs', which have heights and scale radius of about 100 to 300 pc, connecting two or more dark clouds, and `loops' and `bubbles', which are developed forms of arcs, expanding into the disk-halo interface. These have diameters of a few hundred pc to $\sim 1$ kpc. Among the bubbles, we notice a peculiar round-shaped bubble above the nucleus, which could be a large-diameter ($\sim 300$ pc) supernova remnant exploded in the halo over the nucleus. We also find `vertical dust streamers', which comprise bunches of narrow filaments with a thickness of a few tens of pc and are almost perpendicular to the galactic plane, extending coherently for 1 to 2 kpc toward the halo. Finally, we note `short vertical dust filaments' (or spicules) are found in the central region. We interpret these features as due to three-dimensional structures of gas extending from the disk into the halo. We propose a `boiling disk' model where the filamentary features are produced by star-forming activity in the disk as well as the influence of magnetic fluxes. We discuss the implication of the model for the chemical evolution of the ISM in a galaxy disk.

The future policy research agenda of an EU inclusive growth research infrastructure

Year: 2015

description: This report constitutes Deliverable 2.1 ‘Futuring briefing note 1: The future policy research agenda of an EU Inclusive Growth Research Infrastructure’, for Work Package 2 ‘Research Infrastructure strategic forum’ of the InGRID project. The central question of this report is: “What are challenges that the European research community on inclusive growth needs to address to develop a European research infrastructure which will foster evidence-based policy making?” Aiming to get a broad view on this issue, a purposive, non-probability sample of European experts within different academic fields related to issues of inclusive growth was surveyed. The mainly qualitative analysis of the survey responses let to the identification of four main challenges (data, methods, the gap between policy and research and the research context) and four main recommendations linked to this: (1) Data should be the main priority: more and better data are necessary for high-quality comparative research in Europe. (2) The improvement of methods and researchers’ (methodological) skills must go hand in hand with more and better data. (3) Bridging the gap between policy and research is a challenge to be tackled both by policy makers and researchers. (4) A research context that encourages cooperation and innovation and provides the necessary resources should be stimulated. Progressing towards a European research infrastructure on inclusive growth starts with a strong focus on the data, but goes hand in hand with the development and improvement of methods, training and knowledge exchange on these data and methods and community building which includes not only the European researchers from different disciplines, but other relevant stakeholders as well and in addition to that investing (efforts and money) in building bridges and a collaborative climate between policy makers and researchers.
Renormalization in the Gauged Nambu--Jona-Lasinio Model

description: Based on the Cornwall-Jackiw-Tomboulis effective potential, we extensively study nonperturbative renormalization of the gauged Nambu-Jona-Lasinio model in the ladder approximation with standing gauge coupling. Although the pure Nambu-Jona-Lasinio model is not renormalizable, presence of the gauge interaction makes it possible that the theory is renormalized as an interacting continuum theory at the critical line in the ladder approximation. Extra higher dimensional operators (``counter terms'') are not needed for the theory to be renormalized. By virtue of the effective potential approach, the renormalization (``symmetric renormalization'') is performed in a phase-independent manner both for the symmetric and the spontaneously broken phases of the chiral symmetry. We explicitly obtain $β$ function having a nontrivial ultraviolet fixed line for the renormalized coupling as well as the bare one. In both phases the anomalous dimension is very large ($ \ge 1$) without discontinuity across the fixed line. Operator product expansion is explicitly constructed, which is consistent with the large anomalous dimension owing to the appearance of the nontrivial extra power behavior in the Wilson coefficient for the unit operator. The symmetric renormalization breaks down at the critical gauge coupling, which is cured by the generalized renormalization scheme (``$\tM$-dependent renormalization''). Also emphasized is the formal resemblance to the four-fermion theory in less than four dimensions which is renormalizable in $1/N$ expansion.

description: We present a detailed study of the dynamic response of a ring of $N$ equally spaced Josephson junctions to a time-periodic external flux, including screening current effects. The dynamics are described by the resistively shunted Josephson junction model, appropriate for proximity effect junctions, and we include Faraday's law for the flux. We find that the time-averaged $I-V$ characteristics show novel {\em subharmonic giant Shapiro voltage resonances}, which strongly depend on having phase slips or not, on $N$, on the inductance and on the external drive frequency. We include an estimate of the possible experimental parameters needed to observe these quantized voltage spikes.

description: We revisit the instanton-dyon liquid model in the confined phase by using a non-linear Debye-Huckel (DH) resummation for the Coulomb interactions induced by the moduli, followed by a cluster expansion. The organization is shown to rapidly converge and yields center symmetry at high density. The dependence of these results on a finite vacuum angle are also discussed. We also formulate the hypernetted chain (HCN) resummation for the dense instanton-dyon liquid and use it to estimate the liquid pair correlation functions in the DH limit. At very low temperature, the dense limit interpolates between chains and rings of instanton-anti-instanton-dyons and a bcc crystal, with strong topological and magnetic correlations.

description: By combining the generalized exterior algebra of forms over a noncommutative algebra with the gauging of discrete directions and the associated Higgs fields, we consider the construction of the bosonic sector of left-right symmetric models of the form $SU(2)_{L}\otimes SU(2)_{R}\otimes U(1)$. We see that within this formalism maximal use can be made of the gauge connection associated with the non-commutative graded algebra.

description: We conducted a time-series spectroscopical analysis on the Delta Scuti star Beta Cas, known for exhibiting only three independent pulsation frequencies, as a variable star. Our aim was to test whether or not the star presents more pulsation frequencies and pulsation modes besides those previously found in photometric studies. The analysis of mode identification is based on the Moment Method, despite the star being a fast rotator, taking into account previously determined stellar parameters. This is a brief summary of our results and observations.

description: These are lectures presented at the summer course on ``Low Dimensional Quantum Field Theories for Condensed Matter Physicists'', 24 Aug. to 4 Sep. 1992, Trieste, Italy. I review recent work, performed in collaboration primarily with N. Read and Jinwu Ye, on the properties of quantum antiferromagnets in two dimensions. The emphasis is on the properties of the antiferromagnet in states which do not have any long-range magnetic order. The universal spin dynamics in the quantum critical region of number of frustrated and random antiferromagnets is studied; implications for neutron scattering experiments in the lightly-doped cuprates are noted. The nature of the quantum-disordered phase of non-random frustrated antiferromagnets is examined in some detail: the states found have ({\em i\/}) collinear spin correlations, spin-Peierls or valence-bond-solid order, and confined spinons, order and confined spinons or ({\em ii\/}) coplanar spin correlations, no spin-Peierls order and deconfined bosonic spinons.

description: Retrospective meetings play a vital role in agile development by facilitating team reflection on past work to enhance effectiveness. These meetings address various social aspects, including team dynamics, individual performance, processes, and technologies, ultimately leading to actions for improvement. Despite their importance, limited research has explored how these meetings handle forms of social debt, particularly Community Smells -- recurring dysfunctional patterns in team dynamics, such as poor communication or isolated work practices. This study seeks to understand how retrospective meetings address a few core Community Smells, examining whether these meetings help identify smells, make it possible to formulate refactoring strategies, support the monitoring of refactoring actions, and contribute to preventing the most prominent Community Smells. We conducted semi-structured interviews with 15 practitioners from diverse organizations who regularly participate in retrospective meetings. The interviewees shared their experiences with retrospectives, the challenges discussed, and subsequent improvement actions. The study focused on the four most cited Community Smells in the literature -- Lone Wolf, Organizational Silo, Radio Silence, and Black Cloud. Data was analyzed iteratively using a priori coding to examine Community Smells and inductive open coding inspired by Grounded Theory. The findings indicate that retrospective meetings indeed enable the identification of core Community Smells. However, while strategies for refactoring are often formulated, their implementation and monitoring remain inconsistent. Additionally, an emphasis on positive aspects during these meetings may help in preventing Community Smells. This study offers valuable insights to practitioners and researchers, highlighting the importance of addressing social debt in software development within agile practices.

We then reduce the system to the spherically symmetric case and show that all regions of the spacetime can be represented in a single coordinate system, thus revoking the need for junction conditions. We further show that the region exterior to the collapsing region is naturally described by the charged Vaidya spacetime in non-null coordinates.

description: Rising global demand for energy and minerals, driven by population growth and a transition to cleaner energy, has heightened the need for more sustainable resource extraction methods. Conventional mining techniques, such as explosive blasting, pose environmental risks and are energy-intensive. An innovative solution involves employing Slow Releasing Energy Material Agent (SREMA) for breaking orebodies deep underground. SREMA expands upon hydration, generating pressure within predrilled boreholes. This pressure induces fractures in surrounding rock, revealing embedded ores or energy sources. Modified SREMA ensures energy efficiency, achieving a maximum expansive pressure of 68 MPa at 25°C, while mitigating environmental impact by minimising calcium leaching.

description: Este trabalho propõe uma investigação da produção artística e prática clínica de Castiel Vitorino Brasileiro - artista visual, psicóloga e macumbeira - como dispositivo de promoção de cura, crítica da racialidade e reinvenção das memórias do colonialismo. O enquadramento consiste em olhar o colonialismo como fenômeno atualizado e reproduzido incessantemente, enquanto trauma histórico e coletivo, no racismo cotidiano. Falar em trauma, neste caso, é tratar de adoecimentos de sujeitos subalternizados pelo regime de racialização que organiza os corpos (negros e indígenas, no Brasil) entre matáveis e vivíveis. Assim, na articulação entre colonialismo, racismo e os seus modos de mortificação – —ou, em outros termos, de um passado que retorna como ferida aberta ao presente – a obra de Castiel Vitorino Brasileiro se localiza na encruzilhada entre outros modos de subjetivação e descolonização do sujeito, através do cultivo de memórias afro-diaspóricas. Propomos uma análise da obra de Castiel Vitorino Brasileiro como gesto de descolonização epistêmica e insurgência ético-política na contemporaneidade do Brasil, para a qual será mobilizada uma reflexão sobre a produção do corpo negro pelo sistema colonial (Hortense J. Spillers); a redistribuição da violência colonial como autocuidado (Jota Mombaça); os efeitos psíquicos do colonialismo (Frantz Fanon); o racismo cotidiano como trauma colonial (Grada Kilomba); as práticas de mediação e resistência à morte (Achille Mbembe); e a desindentificação como subversão cultural e política (José Esteban Muñoz). O levante de Castiel Vitorino Brasileiro se dá no meneio com que seu corpo escapole da colonialidade que insiste em produzir a racialidade e aprisionar os sujeitos nela identificados. Gozando a liberdade da desobediência com que manipula energias e a violência colonial, a artista, psicóloga e macumbeira produz dispositivos de luta e cura enquanto autocuidado de si e das suas. É principalmente na recriação das memórias, em sua força visionária e subversiva, que o trauma brasileiro é conjurado. Nesse processo, a disrupção do esquecimento tem que ver com a imaginação de uma nova realidade cuja palavra de ordem é libertação e vida.

description: We introduce a one-dimensional PT-symmetric system, which includes the cubic self-focusing, a double-well potential in the form of an infinitely deep potential box split in the middle by a delta-functional barrier of an effective height epsilon, and constant linear gain and loss, gamma, in each half-box. The setting may be realized in microwave photonics. Using numerical methods, we construct PT-symmetric and antisymmetric modes, which represent, respectively, the system's ground state and first excited state, and identify their stability. When they are unstable, the instability leads to blowup, except for the case of epsilon = 0, when an unstable symmetric mode transforms into a weakly oscillating breather, and an unstable antisymmetric mode relaxes into a stable symmetric one. At epsilon > 0, the stability area is much larger for the PT-antisymmetric state than for its symmetric counterpart. The stability areas shrink with with increase of the total power, P. In the linear limit, which corresponds to P --> 0, the stability boundary is found in an analytical form. The stability area of the antisymmetric state originally expands with the growth of gamma, and then disappears at a critical value of gamma.

description: We present new estimates of the spatial two-point correlation function of rich clusters of galaxies selected from the APM Galaxy Survey. We have measured redshifts for a sample of $364$ clusters out to a depth of $\sim 450\hmpc$. The clusters have a mean space density of $\bar{n} = 3.4\times 10^{-5}\hmpccc$. The two-point correlation function, $ξ_{cc}$, for this sample is equal to unity at a pair-separation of $r_0 = 14.3\pm1.75\hmpc$ (2$σ$ errors), consistent with our earlier results from a smaller sample. The new observations provide an accurate determination of the shape of $ξ_{cc}$ to pair-separations of about $50\hmpc$. Our results show that $ξ_{cc}$ has a higher amplitude than expected according to the standard $Ω=1$ cold dark matter (CDM) model on spatial scales $2\simlt s \simlt 50\hmpc$, but are in good agreement with scale-invariant fluctuations in either a low density CDM model or a critical density universe made up of a mixture of hot and cold dark matter. Our results provide strong constraints on so called `co-operative' models of galaxy formation in which the galaxy formation process introduces large-scale structure in the galaxy distribution.

description: Lattice matched GaAs/AlGaAs epitaxial structures with quantum dots are studied under static uniaxial stress applied either along the $[001]$ or $[110]$ crystal directions. We conduct simultaneous measurements of the spectral shifts in the photoluminescence of the bulk GaAs substrate, which relate to strain via deformation potentials $a$ and $b$, and the quadrupolar shifts in the optically detected nuclear magnetic resonance spectra of the quantum dots, which relate to the same strain via the gradient-elastic tensor $S_{ijkl}$. Measurements in two uniaxial stress configurations are used to derive the ratio $b/a=0.241\pm0.008$ in good agreement with previous studies on GaAs. Based on the previously estimated value of $a\approx-8.8$ eV we derive the product of the nuclear quadrupolar moment $Q$ and the $S$-tensor diagonal component in GaAs to be $QS_{11}\approx+0.76\times10^{-6}$ V for $^{75}$As and $QS_{11}\approx-0.37\times10^{-6}$ V for $^{69}$Ga nuclei. In our experiments the signs of $S_{11}$ are directly measurable, which was not possible in the earlier nuclear acoustic resonance studies. Our $QS_{11}$ values are a factor of $\sim$1.4 smaller than those derived from the nuclear acoustic resonance experiments [Phys. Rev. B 10, 4244 (1974)]. The gradient-elastic tensor values measured in this work can be applied in structural analysis of strained III-V semiconductor nanostructures via accurate modelling of their magnetic resonance spectra.

description: Ao abrir o baú do arquivo familiar composto por filmagens Super 8 feitas pelo seu avô, em Angola, na década de 60, Sara Serpa começou um caminho sem retorno. Recognition é o resultado de uma reflexão pessoal e artística sobre o passado colonial de Portugal e da sua própria família, numa necessária intersecção entre as duas esferas – o privado familiar e o histórico colectivo. Para Serpa, abrir esse baú até então desconhecido significou confrontar o silêncio que vive impregnado há décadas de mais nas paredes das casas das famílias portuguesas, em particular daqueles que nasceram, viveram ou combateram em África e na Ásia durante o período colonial. Deste modo, Recognition reflecte um processo de reconhecimento histórico sem o qual será sempre mais difícil compreender certas dinâmicas sociais actuais, herdeiras directas do colonialismo, que se manifestam sob as mais diversas formas de violência social, económica, racial e machista. Recognition é, por isso, simultaneamente um objecto histórico, artístico e político, que nos mostra como as várias linguagens e expressões artísticas conseguem, por vezes, preencher silêncios históricos, sejam estes resultado de uma falta de vontade política, culpa, vergonha, negação, trauma ou até mesmo o mero esquecimento.

description: We present a comprehensive study of voids formation, nucleation and growth in a prototype model of binary alloys subjected to irradiation by using a combined approach based on phase field and rate theories. It is shown that voids formation is caused by interaction of irradiation-produced vacancies through elastic deformation of a lattice and vacancy coupling with composition field of the alloy. Phase diagrams illustrating the formation of states related to solid solution, phase decomposition, and patterning are obtained. Formation of voids from supersaturated ensemble of vacancies is accompanied by composition rearrangement of alloy components. It was found that elastic inhomogeneity leading to the formation of anisotropic precipitates in an initially prepared binary alloy results in the formation of a void super-lattice under irradiation. It was shown that voids nucleate and grow with dose according to diffusion controlled precipitation processes, where universal dynamics of voids growth is revealed. Estimations of main quantitative and statistical characteristics of voids by using material parameters relevant to most of alloys and steels give good agreement with experimental observations.

description: A constraint between thermal fireball parameters arises from the requirement that the balance of strangeness in a fireball is (nearly) zero. We study the impact of this constraint on (multi-)strange (anti-)baryon multiplicities and compare the hadron gas and quark-gluon plasma predictions. We explore the relation between the entropy content and particle multiplicities and show that the data are compatible with the quark-gluon plasma hypothesis, but appear to be inconsistent with the picture of an equilibrated hadron gas fireball. We consider the implications of the results on the dynamics of evolution and decay of the particle source.

description: Similar to knots in S^3, any knot in a lens space has a grid diagram from which one can combinatorially compute all of its knot Floer homology invariants. We give an explicit description of the generators, differentials, and rational Maslov and Alexander gradings in terms of combinatorial data on the grid diagram. Motivated by existing results for the Floer homology of knots in S^3 and the similarity of the combinatorics presented here, we conjecture that a certain family of knots is characterized by their Floer homology. Coupled with work of the third author, an affirmative answer to this would prove the Berge conjecture, which catalogs the knots in S^3 admitting lens space surgeries.

Rejoinder to Reader Reaction "On exact randomization-based covariate-adjusted confidence intervals" by Jacob Fiksel
Creators: name: Zhu, Ke
name: Liu, Hanzhong
Publisher: name: arXiv
Year: 2025
Subjects: subject: Methodology (stat.ME)

description: We applaud Fiksel (2024) for their valuable contributions to randomization-based inference, particularly their work on inverting the Fisher randomization test (FRT) to construct confidence intervals using the covariate-adjusted test statistic. FRT is advocated by many scholars because it produces finite-sample exact p-values for any test statistic and can be easily adopted for any experimental design (Rosenberger et al., 2019; Proschan and Dodd, 2019; Young, 2019; Bind and Rubin, 2020). By inverting FRTs, we can construct the randomization-based confidence interval (RBCI). To the best of our knowledge, Zhu and Liu (2023) are the first to analytically invert the FRT for the difference-in-means statistic. Fiksel (2024) extended this analytical approach to the covariate-adjusted statistic, producing a monotonic p-value function under certain conditions. In this rejoinder, we propose an analytical approach to invert the FRT for test statistics that yield a non-monotonic p-value function, with the studentized t-statistic as an important special case. Exploiting our analytical approach, we can recover the non-monotonic p-value function and construct RBCI based on the studentized t-statistic. The RBCI generated by the proposed analytical approach is guaranteed to achieve the desired coverage probability and resolve the contradiction between Luo et al. (2021) and Wu and Ding (2021). Simulation results validate our findings and demonstrate that our method is also computationally efficient.
