description: In questo articolo descriviamo l’impatto che il campo dell’ecologia politica urbana ha sul mondo accademico e nell’elaborazione delle politiche; e sosteniamo che questo corpus di studi ha una posizione unica per affrontare alcune delle questioni politiche urgenti relative all’urbanizzazione e al cambiamento climatico. Descriviamo le principali epistemologie, ontologie e metodologie dell’ecologia politica urbana ed esploriamo in che misura queste possano affrontare il disastro sistemico che chiamiamo ‘cambiamento climatico’. Il nostro obiettivo principale è dimostrare che la ricerca accademica può e deve rimanere rilevante per la politica di un pianeta che si sta surriscaldando.

Optimized programs from (non-constructive) proofs by the light (monotone) Dialectica interpretation

Subjects: Program extraction from (classical) proofs, Proof Mining, complexity of extracted programs, Gödel's functional Dialectica interpretation, non-computational-meaning (uniform) existential and universal quantifiers, proof complexity, functionals of finite type, software and systems verification, combinatorial logic, computational complexity, proof-carrying code.

description: This thesis presents a new optimization of Gödel’s Dialectica interpretation
 for the extraction of more efficient exact realizers from (classical) arithmeti-
 cal proofs. The “light” variant of Dialectica also combines and even more
 smoothly with Kohlenbach’s “monotone” optimization of Gödel’s functional
 interpretation for the extraction of more efficient majorants and bounds from
 (classical) monotonic arithmetical and even analytical proofs. “Light Dialec-
 tica” is obtained by adapting Berger’s “uniform” or “non-computational”
 quantifiers. Moreover, its presentation is given in Natural Deduction style,
 as an improvement of Jørgensen’s recent adaptation of pure Gödel’s Dialec-
 tica. A number of concrete examples are treated on the computer by means
 of the novel technique. The machine comparison with the more established
 program-synthesis technique of refined A-translation shows a very good per-
 formance of Light Dialectica, which is outperformed only in the case of Dick-
 son’s Lemma. Also the theory of synthesis of feasible, poly-time computable
 programs is developed for the new “Light Monotone Dialectica” extraction
 technique. Two pre-existent frameworks due to Cook-Urquhart-Ferreira and
 respectively Kohlenbach are crossbreeded for this purpose into a “poly-time
 bounded Analysis”. The theoretical result is promising, yet practical examples
 are to be found for the difference with the pure Kohlenbach’s “polynomially
 bounded Analysis”.

Four-vortex motion around a circular cylinder

description: The motion of two pairs of counter-rotating point vortices placed in a uniform flow past a circular cylinder is studied analytically and numerically. When the dynamics is restricted to the symmetric subspace---a case that can be realized experimentally by placing a splitter plate in the center plane---, it is found that there is a family of linearly stable equilibria for same-signed vortex pairs. The nonlinear dynamics in the symmetric subspace is investigated and several types of orbits are presented. The analysis reported here provides new insights and reveals novel features of this four-vortex system, such as the fact that there is no equilibrium for two pairs of vortices of opposite signs on the opposite sides of the cylinder. (It is argued that such equilibria might exist for vortex flows past a cylinder confined in a channel.) In addition, a new family of opposite-signed equilibria on the normal line is reported. The stability analysis for antisymmetric perturbations is also carried out and it shows that all equilibria are unstable in this case.

description: The most likely spin assignments of the recently discovered 126 GeV resonance are spin 0 or 2. In order to distinguish the two, we construct an effective Lagrangian model which comprises interactions of a spin-2 electroweak singlet or triplet state with the SM gauge bosons. Within this model, cross sections and differential distributions are calculated and implemented within the Monte Carlo program VBFNLO, which simulates vector-boson-fusion processes at hadron colliders at NLO QCD accuracy. We study the phenomenology of spin-2 resonances produced in vector-boson-fusion processes at the LHC. Specifically, we consider light Higgs-like spin-2 resonances decaying into two photons and show how angular distributions allow us to distinguish between a Standard Model Higgs and a spin-2 resonance. We also investigate the characteristics of heavy spin-2 resonances which decay into two weak gauge bosons, leading to a four-lepton final state.

description: A theoretical study of the magnon-drag Peltier and Seebeck effects in ferromagnetic metals is presented. A magnon heat current is described perturbatively from the microscopic viewpoint with respect to electron--magnon interactions and the electric field. Then, the magnon-drag Peltier coefficient $Π_\MAG$ is obtained as the ratio between the magnon heat current and the electric charge current. We show that $Π_\MAG=C_\MAG T^{5/2}$ at a low temperature $T$; that the coefficient $C_\MAG$ is proportional to the spin polarization $P$ of the electric conductivity; and that $P>0$ for $C_\MAG<0$, but $P<0$ for $C_\MAG>0$. From experimental results for magnon-drag Peltier effects, we estimate that the strength of the electron--magnon interaction is about 0.3 eV$\cdotÅ^{3/2}$ for permalloy.

description: Pulse-pileup affects most photon counting systems and occurs when photon detections occur faster than the detector's registration and recovery time. At high input rates, shaped pulses interfere and the source spectrum, as well as intensity information, get distorted. For instruments using bipolar pulse shaping there are two aspects to consider: `peak' and `tail' pileup effects, which raise and lower the measured energy, respectively. Peak effects have been extensively modeled in the past. Tail effects have garnered less attention due to the increased complexity: bipolar tails mean the tail pulse-height measurement depends on events in more than one time interval. We leverage previous work to derive an accurate, semi-analytical prediction for peak and tail pileup, up to high orders. We use the true pulse shape from the detectors of the Fermi Gamma-ray Burst Monitor. The measured spectrum is calculated by writing exposure time as a state-space expansion of overlapping pileup states and is valid up to very high rates. This expansion models losses due to fixed and extendable deadtime by averaging overlap configurations. Additionally, the model correctly predicts energy-dependent losses due to tail subtraction (sub-threshold) effects. We discuss pileup losses in terms of the true rate of photon detections versus the recorded count rate.

Book review: Dreams, Vietnam and Other Dreams, by Marc Levy

Publisher: name: International Journal of Dream Research
Year: 2019

description: The former infantry medic Marc Levy published his dream reports, which he was recording regularly for one year, 45 years after he returned from Vietnam War. After the war, he was suffering from severe nightmares related to war experiences. Those dreams are also published in another book. In his newer dreams, war themes are less frequently occurring. They mostly represent daily concerns, and severe threatening dream themes are occurring rarely, but war themes are still reported. In some dreams, severe conflicts are escalating between the dream-self and other dream characters, where the dream-self is also physically violent. This books offer future research a possibility to compare dream contents of idiopathic and posttraumatic nightmare dreamers over a long time period.

With or without you? Dreaming about the romantic partner – A case study

Publisher: name: International Journal of Dream Research
Year: 2019

description: Romantic relations do not only play a major role in pop songs like the U2 song “With or without you” but also in “real” life. Empirical data support the continuity hypothesis of dreaming as romantic partners are quite prominent in dreams; however, content analytic studies of partner dreams are quite scarce. The present dream series over a four-year time period (included a romantic relationship) of a female dreamer included 132 dream reports. Partner-related activities (sexuality, friendly interactions) are more prominent in dreams with the partner compared to dreams without the partner. After separation, the friendly interactions in partner dreams decreased and negative emotions increased. This single-case study might stimulate research to take a closer look on ex-partner dreams and test whether they are helpful – also within a clinical context (psychotherapy) – in coping with the separation.

description: We study a retarded potential solution of a massless scalar field in curved space-time. In a special ansatz for a particle at rest whose magnitude of the (scalar) charge is changing with time, we found an exact analytic solution. The solution indicates that the phase velocity of the retarded potential of a non-moving scalar charge is position dependent, and may easily be greater than the speed of light at a given point. In the case of the Schwarzschild space-time, at the horizon, the phase velocity becomes infinitely faster than the coordinate speed of light at that point. Superluminal phase velocity is relatively common phenomenon, with the the phase velocity of the massive Klein-Gordon field as the best known example. We discuss why it is possible to have modes with superluminal phase velocity even for a massless field.

description: In this paper we assess the present status of dark matter direct searches by means of Bayesian statistics. We consider three particle physics models for spin-independent dark matter interaction with nuclei: elastic, inelastic and isospin violating scattering. We shortly present the state of the art for the three models, marginalising over experimental systematics and astrophysical uncertainties. Whatever the scenario is, XENON100 appears to challenge the detection region of DAMA, CoGeNT and CRESST. The first aim of this study is to rigorously quantify the significance of the inconsistency between XENON100 data and the combined set of detection (DAMA, CoGeNT and CRESST together), performing two statistical tests based on the Bayesian evidence. We show that XENON100 and the combined set are inconsistent at least at 2 sigma level in all scenarios but inelastic scattering, for which the disagreement drops to 1 sigma level. Secondly we consider only the combined set and hunt the best particle physics model that accounts for the events, using Bayesian model comparison. The outcome between elastic and isospin violating scattering is inconclusive, with the odds 2:1, while inelastic scattering is disfavoured with the odds of 1:32 because of CoGeNT data. Our results are robust under reasonable prior assumptions. We conclude that the simple elastic scattering remains the best model to explain the detection regions, since the data do not support extra free parameters. Present direct searches therefore are not able to constrain the particle physics interaction of the dark matter. The outcome of consistency tests implies that either a better understanding of astrophysical and experimental uncertainties is needed, either the dark matter theoretical model is at odds with the data.

On the decoupling of mirror fermions

description: An approach to the formulation of chiral gauge theories on the lattice is to start with a vector-like theory, but decouple one chirality (the "mirror" fermions) using strong Yukawa interactions with a chirally coupled "Higgs" field. While this is an attractive idea, its viability needs to be tested with nonperturbative studies. The model that we study here, the so-called "3-4-5" model, is anomaly free and the presence of massless states in the mirror sector is not required by anomaly matching arguments, in contrast to the "1-0" model that was studied previously. We have computed the polarization tensor in this theory and find a directional discontinuity that appears to be nonzero in the limit of an infinite lattice, which is equivalent to the continuum limit at fixed physical volume. We show that a similar behavior occurs for the free massless Ginsparg-Wilson fermion, where the polarization tensor is known to have a directional discontinuity in the continuum limit. We thus find support for the conclusion that in the continuum limit of the 3-4-5 model, there are massless charged modes in the mirror sector so that it does not decouple from the light sector. The value of the discontinuity we obtain allows for two interpretations: either a chiral gauge theory does not emerge and mirror-sector fermions in a chiral anomaly free representation remain massless, or a massless vectorlike mirror fermion appears. We end by discussing some questions for future study.
description: A normalization error in the code was found, which causes the conclusions to drastically change from the previous version. The new results indicate that massless mirror modes are present. Discussion of their nature and interpretation is added as well as more relevant references. Final published version, updated with expanded comments on the idea of decoupling. (32 pages, 9 figures)

description: This note describes non-asymptotic variance and tail bounds for order statistics of samples of independent identically distributed random variables. Those bounds are checked to be asymptotically tight when the sampling distribution belongs to a maximum domain of attraction. If the sampling distribution has non-decreasing hazard rate (this includes the Gaussian distribution), we derive an exponential Efron-Stein inequality for order statistics: an inequality connecting the logarithmic moment generating function of centered order statistics with exponential moments of Efron-Stein (jackknife) estimates of variance. We use this general connection to derive variance and tail bounds for order statistics of Gaussian sample. Those bounds are not within the scope of the Tsirelson-Ibragimov-Sudakov Gaussian concentration inequality. Proofs are elementary and combine Rényi's representation of order statistics and the so-called entropy approach to concentration inequalities popularized by M. Ledoux.

description: We calculate the condensate fraction and the condensate and non-condensate spatial and momentum distribution of the Bose-Hubbard model in a trap. From our results, it is evident that using approximate distributions can lead to erroneous experimental estimates of the condensate. Strong interactions cause the condensate to develop pedestal-like structures around the central peak that can be mistaken as non-condensate atoms. Near the transition temperature, the peak itself can include a significant non-condensate component. Using distributions generated from QMC simulations, experiments can map their measurements for higher accuracy in identifying phase transitions and temperature.

description: In this paper we describe a formalism for generating exclusive final states in diffractive excitation, based on the optical analogy where diffraction is fully determined by the absorption into inelastic channels. The formalism is based on the Good--Walker formalism for diffractive excitation, and it is assumed that the virtual parton cascades represent the diffractive eigenstates defined by a definite absorption amplitude. We emphasize that, although diffractive excitation is basically a quantum-mechanical phenomenon with strong interference effects, it is possible to calculate the different interfering components to the amplitude in an event generator, add them and thus calculate the reaction cross section for exclusive diffractive final states. The formalism is implemented in the DIPSY event generator, introducing no tunable parameters beyond what has been determined previously in studies of non-diffractive events. Some early results from DIS and proton-proton collisions are presented, and compared to experimental data.
Lattice Boltzmann modeling of multiphase flows at large density ratio with an improved pseudopotential model

description: Owing to its conceptual simplicity and computational efficiency, the pseudopotential multiphase lattice Boltzmann (LB) model has attracted significant attention since its emergence. In this work, we aim to extend the pseudopotential LB model to simulate multiphase flows at large density ratio and relatively high Reynolds number. First, based on our recent work [Li et al., Phys. Rev. E. 86, 016709 (2012)], an improved forcing scheme is proposed for the multiple-relaxation-time pseudopotential LB model in order to achieve thermodynamic consistency and large density ratio in the model. Next, through investigating the effects of the parameter a in the Carnahan-Starling equation of state, we find that the interface thickness is approximately proportional to 1/sqrt(a). Using a smaller a will lead to a wider interface thickness, which can reduce the spurious currents and enhance the numerical stability of the pseudopotential model at large density ratio. Furthermore, it is found that a lower liquid viscosity can be gained in the pseudopotential model by increasing the kinematic viscosity ratio between the vapor and liquid phases. The improved pseudopotential LB model is numerically validated via the simulations of stationary droplet and droplet oscillation. Using the improved model as well as the above treatments, numerical simulations of droplet splashing on a thin liquid film are conducted at a density ratio in excess of 500 with Reynolds numbers ranging from 40 to 1000. The dynamics of droplet splashing is correctly reproduced and the predicted spread radius is found to obey the power law reported in the literature.

description: The fluctuation theorem characterizes the distribution of the dissipation in nonequilibrium systems and proves that the average dissipation will be positive. For a large system with no external source of fluctuation, fluctuations in properties will become unobservable and details of the fluctuation theorem are unable to be explored. In this letter, we consider such a situation and show how a fluctuation theorem can be obtained for a small open subsystem within the large system. We find that a correction term has to be added to the large system fluctuation theorem due to correlation of the subsystem with the surroundings. Its analytic expression can be derived provided some general assumptions are fulfilled, and its relevance it checked using numerical simulations.

description: We consider the open superstring action in AdS_5 x S^5 background with the bilinear Wess-Zumino term, which has been modified in such a way that a certain total derivative term is absent, and give the covariant description of supersymmetric D-branes. We show that the modification of bilinear Wess-Zumino term is necessary to describe correctly the 1/2-BPS D(-1)-brane in AdS_5 x S^5 background, while the classification of other supersymmetric D-branes does not depend on such modification.

description: By presenting linear and nonlinear gyrokinetic studies, based on a balanced neutral beam injection deuterium discharge from the DIII-D tokamak, we demonstrate that impurities alter the scaling of the transport on the charge and mass of the main species, and even more importantly, they can dramatically change the energy transport even in relatively small quantities. A poloidally varying equilibrium electrostatic potential can lead to a strong reduction or sign change of the impurity peaking factor due to the combined effect of the in-out impurity density asymmetry and the EXB drift of impurities. We present an approximate expression for the impurity peaking factor and demonstrate that impurity peaking is not significantly affected by impurity self-collisions.

Exploring the Use of Video Games as an Educational Intervention, with a Focus on Training Cognitive Skills Involved in Reading for Children Aged 7 to 11 with Dyslexia

description: Over the last 20 years research has explored potential cognitive benefits of playing video games. One avenue has investigated whether action video game play can improve areas of cognitive deficit for certain groups. Franceschini et al (2013) hypothesised that playing these games would improve attentional deficits for individuals with dyslexia, subsequently improving reading skills. Studies exploring this hypothesis have observed improvements in reading. Yet as an emerging area of research that suffers from methodological weaknesses and a lack of exploration in English, further investigation is warranted.The present research employed a mixed-methods approach. A constructive replication of Franceschini et al (2017) experiment was conducted to explore the effectiveness of a video game intervention among English-speaking children aged 7-11 with dyslexia (n= 14). Additionally, participant voice was deemed important, therefore semi-structured interviews supported by visual methods were utilised to explore how participants would design video games for the classroom.Quantitative analysis revealed no significant improvement on cognitive or reading measures, contrasting with Franceschini’s findings. Several explanations for the differing findings are proposed, however, as different results were unexpected, this raises questions around the reliability and transferability of the previous findings. While the use of video games to improve reading was not supported here, this does not eliminate the potential of video games in the classroom. Thematic analysis of interviews exploring participants’ perspectives identified six themes. Participants highlighted affordances of video games in the classroom, including the potential to be used purely for entertainment and as an escape. Furthermore, the importance of autonomy in video game design was emphasised, as well as the importance of inclusion and ease of use. Participants also recognised the importance of considering the risks and restrictions of implementing video game technology in the classroom. These findings are discussed within a new version of the technology acceptance model.
Shell evolution and its indication on the isospin dependence of the spin-orbit splitting

description: The available experimental data on shell evolution indicate that the strength of the spin-orbit (SO) single-particle potential may be enhanced in neutron-rich nuclei. We observe that such a simple scheme destroys the Harmonic Oscillator (HO) magic numbers N=8 and 20 and generates new SO magic numbers like N=6, 14, 16, 32 and 34. The traditional SO magic numbers like N=28 and 50 and N=14 seen in $^{22}$O are eroded somehow in neutron-rich nuclei due to the sensitivity of larger-$l$ orbitals to the depth of the central potential but they are more robust than the HO magic numbers. The N=82 shell closure persists in neutron-rich nuclei while HO shell closures like N=40 and 70 do not emerge. Both mechanisms contribute to enhancing the N=56 and 90 gaps by splitting the $1d_{5/2}$ and $0g_{7/2}$ and the $0h_{9/2}$ and $1f_{7/2}$ orbitals.

Noise generation in the solid Earth, oceans, and atmosphere, from non-linear interacting surface gravity waves in finite depth

description: Oceanic pressure measurements, even in very deep water, and atmospheric pressure or seismic records, from anywhere on Earth, contain noise with dominant periods between 3 and 10 seconds, that is believed to be excited by ocean surface gravity waves. Most of this noise is explained by a nonlinear wave-wave interaction mechanism, and takes the form of surface gravity waves, acoustic or seismic waves. Previous theoretical works on seismic noise focused on surface (Rayleigh) waves, and did not consider finite depth effects on the generating wave kinematics. These finite depth effects are introduced here, which requires the consideration of the direct wave-induced pressure at the ocean bottom, a contribution previously overlooked in the context of seismic noise. That contribution can lead to a considerable reduction of the seismic noise source, which is particularly relevant for noise periods larger than 10 s. The theory is applied to acoustic waves in the atmosphere, extending previous theories that were limited to vertical propagation only. Finally, the noise generation theory is also extended beyond the domain of Rayleigh waves, giving the first quantitative expression for sources of seismic body waves. In the limit of slow phase speeds in the ocean wave forcing, the known and well-verified gravity wave result is obtained, which was previously derived for an incompressible ocean. The noise source of acoustic, acoustic-gravity and seismic modes are given by a mode-specific amplification of the same wave-induced pressure field near the zero wavenumber.

description: This is the first in a series of papers laying the foundations for a differential graded approach to derived differential geometry (and other geometries in characteristic zero). In this paper, we study theories of supercommutative algebras for which infinitely differentiable functions can be evaluated on elements. Such a theory is called a super Fermat theory. Any category of superspaces and smooth functions has an associated such theory. This includes both real and complex supermanifolds, as well as algebraic superschemes. In particular, there is a super Fermat theory of C-infinity superalgebras. C-infinity superalgebras are the appropriate notion of supercommutative algebras in the world of C-infinity rings, the latter being of central importance both to synthetic differential geometry and to all existing models of derived smooth manifolds. A super Fermat theory is a natural generalization of the concept of a Fermat theory introduced by E. Dubuc and A. Kock. We show that any Fermat theory admits a canonical superization, however not every super Fermat theory arises in this way. For a fixed super Fermat theory, we go on to study a special subcategory of algebras called near-point determined algebras, and derive many of their algebraic properties.

description: Four dimensional gauge theories in anti-de Sitter space, including pure Yang-Mills theory, exhibit a quantum phase transition between a deconfined phase and a confined phase as the gauge coupling is varied. We explore various mechanisms by which this may occur, both in a fixed background and in the presence of gravity. We also make a number of observations on the dynamics of four dimensional supersymmetric gauge theories in anti-de Sitter space.

Heterotopias of transition. Notes from a research program

Year: 2023

description: Ecological transition is generally seen to ask for profound changes. The city condenses many aspects of the issue, not least the variety of spatial and temporal scales involved. The article examines different declinations of the concept of change and the relationship between space and time that they entail. The issue is placing this relationship in the context of modern space-time topology. This has recently seen new anticipatory approaches come to the fore, that abandon the linearity of the relationship between present and future in favour of recursive structures centred on eschatological, catastrophic or regenerative visions. Such emerging topologies, which would seem to evoke the traditional concepts of utopia and dystopia, are examined in the light of the notion of heterotopia formulated by Foucault, with which they share much while contradicting its transgressive scope, its ability to open up at once to the elsewhere and the otherwise. The question is how to think transition in heterotopic terms. Some current experiences can be read as heterotopias, but we need to develop the ability to distinguish heterotopias from ‘autotopias’, which are designed to prevent any real change.
