Valutazione della ricerca

description: Seminario al Dipartimento Culture Politiche Società, Università di Torino, 17 settembre 2024

Un duplice approccio: cosa può fare Open Science per la valutazione (e la comunicazione scientifica in generale) e cosa può fare la valutazione per l'Open Science

Cosa non funziona nella comuncazione scientifica attuale: ritrattazioni, frodi, cartelli di citazioni, papermills...

Come può aiutare la Open Science: se l'intero processo è trasparente e tutti i passaggi sono disponibili, migliorano integrità e riproducibilità

La riforma della valutazione è in atto: COARA, chi ha firmato e cosa fa il capitolo nazionale

...un'occasione da non perdere

description: We consider a nonlinear Schrodinger equation with power nonlinearity, either on a compact manifold without boundary, or on the whole space in the presence of harmonic confinement, in space dimension one and two. Up to introducing an extra superlinear damping to prevent finite time blow up, we show that the presence of a sublinear damping always leads to finite time extinction of the solution in 1D, and that the same phenomenon is present in the case of small mass initial data in 2D.

description: First order Hamiltonian operators of differential-geometric type were introduced by Dubrovin and Novikov in 1983, and thoroughly investigated by Mokhov. In 2D, they are generated by a pair of compatible flat metrics $g$ and $\tilde g$ which satisfy a set of additional constraints coming from the skew-symmetry condition and the Jacobi identity. We demonstrate that these constraints are equivalent to the requirement that $\tilde g$ is a linear Killing tensor of $g$ with zero Nijenhuis torsion. This allowed us to obtain a complete classification of $n$-component operators with $n\leq 4$ (for $n=1, 2$ this was done before). For 2D operators the Darboux theorem does not hold: the operator may not be reducible to constant coefficient form. All interesting (non-constant) examples correspond to the case when the flat pencil $g, \tilde g$ is not semisimple, that is, the affinor $\tilde g g^{-1}$ has non-trivial Jordan block structure. In the case of a direct sum of Jordan blocks with distinct eigenvalues we obtain a complete classification of Hamiltonian operators for any number of components $n$, revealing a remarkable correspondence with the class of trivial Frobenius manifolds modelled on $H^*(CP^{n-1})$.

Nonparametric specification for non-stationary time series regression

Subjects: subject: Statistics Theory (math.ST)

description: We investigate the behavior of the Generalized Likelihood Ratio Test (GLRT) (Fan, Zhang and Zhang [Ann. Statist. 29 (2001) 153-193]) for time varying coefficient models where the regressors and errors are non-stationary time series and can be cross correlated. It is found that the GLRT retains the minimax rate of local alternative detection under weak dependence and non-stationarity. However, in general, the Wilks phenomenon as well as the classic residual bootstrap are sensitive to either conditional heteroscedasticity of the errors, non-stationarity or temporal dependence. An averaged test is suggested to alleviate the sensitivity of the test to the choice of bandwidth and is shown to be more powerful than tests based on a single bandwidth. An alternative wild bootstrap method is proposed and shown to be consistent when making inference of time varying coefficient models for non-stationary time series.

description: Cylindrospermopsin (CYN) is being detected in surface waters more commonly and frequently worldwide. This stable, extracellular cyanotoxin causes protein synthesis inhibition, thus posing a risk to aquatic biota, including macrophytes, which serve as primary producers. Nevertheless, data regarding the effects caused by environmental concentrations of CYN is still limited. In the presented study, the uptake of CYN at environmental concentrations by the submerged macrophyte Egeria densa was investigated. Bioaccumulation, changes in the plant biomass, as well as shoot-length were assessed as responses. Variations in the cellular H2O2 levels, antioxidative enzyme activities, as well as concentrations and ratios of the photosynthetic pigments were also measured. E. densa removed 54% of CYN within 24 h and up to 68% after 336 h; however, CYN was not bioaccumulated. The antioxidative enzyme system was activated by CYN exposure. Pigment concentrations decreased with exposure but normalized after 168 h. The chlorophyll a to b ratio increased but normalized quickly thereafter. Carotenoids and the ratio of carotenoids to total chlorophylls increased after 96 h suggesting participation in the antioxidative system. Growth stimulation was observed. The ability to remove CYN and resistance to CYN toxicity within 14 days proved E. densa as suitable for phytoremediation; nonetheless, prolonged exposure (32 days) resulted in adverse effects related to CYN uptake, which needs to be studied further.
Inheritance of solar short- and long-lived radionuclides from molecular clouds and the unexceptional nature of the solar system

description: Apparent excesses in early-solar $^{26}$Al, $^{36}$Cl, $^{41}$Ca, and $^{60}$Fe disappear if one accounts for ejecta from massive-star winds concentrated into dense phases of the ISM in star-forming regions. The removal of apparent excesses is evident when wind yields from Wolf-Rayet stars are included in the plot of radionuclide abundances vs. mean life. The resulting trend indicates that the solar radionuclides were inherited from parental molecular clouds with a characteristic residence time of 10$^8$ years. This residence time is of the same order as the present-day timescale for conversion of molecular cloud material into stars. The concentrations of these extinct isotopes in the early solar system need not signify injection from unusual proximal stellar sources, but instead are well explained by normal concentrations in average star-forming clouds. The results imply that the efficiency of capture is greater for stellar winds than for supernova ejecta proximal to star-forming regions.
Hot Accretion Flows Around Black Holes

Subjects: subject: High Energy Astrophysical Phenomena (astro-ph.HE)
subject: FOS: Physical sciences

description: Black hole accretion flows can be divided into two broad classes: cold and hot. Cold accretion flows, which consist of cool optically thick gas, are found at relatively high mass accretion rates. Prominent examples are the standard thin disk, which occurs at a fraction of the Eddington mass accretion rate, and the slim disk at super-Eddington rates. These accretion flows are responsible for luminous systems such as active galactic nuclei radiating at or close to the Eddington luminosity and black hole X-ray binaries in the soft state. Hot accretion flows, the topic of this review, are virially hot and optically thin. They occur at lower mass accretion rates, and are described by models such as the advection-dominated accretion flow and luminous hot accretion flow. Because of energy advection, the radiative efficiency of these flows is in general lower than that of a standard thin accretion disk. Moreover, the efficiency decreases with decreasing mass accretion rate. Observations show that hot accretion flows are associated with jets. In addition, theoretical arguments suggest that hot flows should produce strong winds. Hot accretion flows are believed to be present in low-luminosity active galactic nuclei and in black hole X-ray binaries in the hard and quiescent states. The prototype is Sgr A*, the ultra-low-luminosity supermassive black hole at our Galactic center. The jet, wind and radiation from a supermassive black hole with a hot accretion flow can interact with the external interstellar medium and modify the evolution of the host galaxy. Details of this "maintenance-mode feedback" could, in principle, be worked out through theoretical studies and numerical simulations of hot accretion flows.

description: James D. Edgar’s speech from the Medical History Society meeting in 1926 gives brief glimpses into the history of the War of 1812, including the lack of support due to poor planning, with more specific descriptions of ailments of individuals during the conflict, one of which was an epidemic that affected large swaths of men. Edgar notes that doctors and surgeons during this war had similar high rankings as officers in the military, adding to their importance during this time. Ultimately, despite the poor planning and medical departments at the whim of others in control, it did prove the importance of having medical care readily available and bolstered the formation of general hospitals outside of wartime.

description: We report on the crystal structure, physical properties, and electronic structure calculations for the ternary pnictide compound EuCr2As2. X-ray diffraction studies confirmed that EuCr2As2 crystalizes in the ThCr2Si2-type tetragonal structure (space group I4/mmm). The Eu ions are in a stable divalent state in this compound. Eu moments in EuCr2As2 order magnetically below Tm = 21 K. A sharp increase in the magnetic susceptibility below Tm and the positive value of the paramagnetic Curie temperature obtained from the Curie-Weiss fit suggest dominant ferromagnetic interactions. The heat capacity exhibits a sharp λ-shape anomaly at Tm, confirming the bulk nature of the magnetic transition. The extracted magnetic entropy at the magnetic transition temperature is consistent with the theoretical value Rln(2S+1) for S = 7/2 of the Eu2+ ion. The temperature dependence of the electrical resistivity \r{ho}(T) shows metallic behavior along with an anomaly at 21 K. In addition, we observe a reasonably large negative magneto-resistance (~ -24%) at lower temperature. Electronic structure calculations for EuCr2As2 reveal a moderately high density of states of Cr-3d orbitals at the Fermi energy, indicating that the nonmagnetic state of Cr is unstable against magnetic order. Our density functional calculations for EuCr2As2 predict a G-type AFM order in the Cr sublattice. The electronic structure calculations suggest a weak interlayer coupling of the Eu moments.

Acoustic instability in the neutral precursor region of collisionless shocks propagating into partially ionized plasmas

Year: 2014
Subjects: subject: High Energy Astrophysical Phenomena (astro-ph.HE)

description: Recent studies about collisionless shocks in partially ionized plasmas showed that some of neutral particles leak into the shock upstream region from the downstream region. In this paper, we perform a linear analysis and show that acoustic waves are unstable in the neutral precursor region. The acoustic instability amplifies fluctuations of magnetic field and density in the upstream region. The fluctuations are indispensable for the diffusive shock acceleration and could be important for the downstream turbulence.

description: The present U.S. system of regulating the production, importation, and marketing of sugar is an outgrowth of Government regulation of the sugar trade dating from Colonial times. Similar systems have developed in most other countries, particularly those which import sugar. The U.S. Sugar Quota System has benefited domestic sugar producers by providing stable prices at favorable levels. These prices also have encouraged the production and use of substitute sweeteners, particularly corn sirup and dextrose in certain industries. However, sugar is, by far, the most widely used sweetener in the U.S. and is likely to retain this position.

In this paper, we show that the quotient space $X/(A_1,A_2,...,A_n)$ obtained from $X$ by collapsing each of the sets $A_i$'s to a point, is also locally 1-connected. Moreover, we prove that the induced continuous homomorphism of quasitopological fundamental groups is surjective. Finally, we give some applications to find out some properties of the fundamental group of the quotient space $X/(A_1,A_2,...,A_n)$.

Nanosystem Self-Assembly Pathways Discovered via All-Atom Multiscale Analysis

description: We consider the self-assembly of composite structures from a group of nanocomponents, each consisting of particles within an $N$-atom system. Self-assembly pathways and rates for nanocomposites are derived via a multiscale analysis of the classical Liouville equation. From a reduced statistical framework, rigorous stochastic equations for population levels of beginning, intermediate, and final aggregates are also derived. It is shown that the definition of an assembly type is a self-consistency criterion that must strike a balance between precision and the need for population levels to be slowly varying relative to the time scale of atomic motion. The deductive multiscale approach is complemented by a qualitative notion of multicomponent association and the ensemble of exact atomic-level configurations consistent with them. In processes such as viral self-assembly from proteins and RNA or DNA, there are many possible intermediates, so that it is usually difficult to predict the most efficient assembly pathway. However, in the current study, rates of assembly of each possible intermediate can be predicted. This avoids the need, as in a phenomenological approach, for recalibration with each new application. The method accounts for the feedback across scales in space and time that is fundamental to nanosystem self-assembly. The theory has applications to bionanostructures, geomaterials, engineered composites, and nanocapsule therapeutic delivery systems.

description: We present evidence that spots imaged using astronomical CCDs do not exactly scale with flux: bright spots tend to be broader than faint ones, using the same illumination pattern. We measure that the linear size of spots or stars, of typical size 3 to 4 pixels FWHM, increase linearly with their flux by up to $2\%$ over the full CCD dynamic range. This brighter-fatter effect affects both deep-depleted and thinned CCD sensors. We propose that this effect is a direct consequence of the distortions of the drift electric field sourced by charges accumulated within the CCD during the exposure and experienced by forthcoming light-induced charges in the same exposure. The pixel boundaries then become slightly dynamical: overfilled pixels become increasingly smaller than their neighbors, so that bright star sizes, measured in number of pixels, appear larger than those of faint stars. This interpretation of the brighter-fatter effect implies that pixels in flat-fields should exhibit statistical correlations, sourced by Poisson fluctuations, that we indeed directly detect. We propose to use the measured correlations in flat-fields to derive how pixel boundaries shift under the influence of a given charge pattern, which allows us to quantitatively predict how star shapes evolve with flux. This physical model of the brighter-fatter effect also explains the commonly observed phenomenon that the spatial variance of CCD flat-fields increases less rapidly than their average.

Recently, we developed a relevant no-core shell model technique which we successfully applied in first calculations of lightest $Λ$ hypernuclei. The use of a translationally invariant finite harmonic oscillator basis allows us to employ large model spaces, compared to traditional shell model calculations, and use realistic nucleon-nucleon and nucleon-hyperon interactions (such as those derived from EFT). We discuss formal aspects of the methodology, show first demonstrative results for ${}_Λ^3$H, ${}_Λ^4$H and ${}^4_Λ$He, and give outlook.

description: The concept of local self-governance is not new as it has its roots in ancient time even before the era of Mauryan emperors. This paper depicts the journey of local self-governance from antediluvian time to 21st century. Further, in the current scenario Information and Communication Technology (ICT) has emerged as a successful tool for dissemination of various e-governance services and in this regard the Government of India has formulated NeGP with adequate service delivery mechanism. With the inculcation of ICT, various applications were designed by central as well as state governments which lead towards strengthening of PRIs for rural reform. This paper also throws some light on necessity of ICT in self-governance along with some case studies.

From the analytical expressions of the Faustmann criterion and the Expected Long-Run Average Yield, we deduce in presence of storm risk the influence of criteria and of discount rate in terms of optimal thinnings and cutting age. We discuss the validity of using a risk adjusted discount rate (a rate of storm risk added to the discount rate) without risk to mimic the storm risk case in terms of optimal thinnings.

description: In this work, we study the impact of a relay node to a network with a finite number of users-sources and a destination node. We assume that the users have saturated queues and the relay node does not have packets of its own; we have random access of the medium and the time is slotted. The relay node stores a source packet that it receives successfully in its queue when the transmission to the destination node has failed. The relay and the destination nodes have multi-packet reception capabilities. We obtain analytical equations for the characteristics of the relay's queue such as average queue length, stability conditions etc. We also study the throughput per user and the aggregate throughput for the network.

description: Aotearoa New Zealand faces substantial challenges to respond to natural hazard risk and climate change. This is compounded by the need to provide residential zoned land for urban housing needs, commercial and industrial land for economic development and also maintain rural land for primary production. Scalable processes and frameworks are needed to support effective and efficient decision-making that is both robust and replicable. Therefore, tools that can be used to face these challenges and avoid maladaptation are needed. This report demonstrates ways in which RiskScape™, an open-source spatial data processing application used for multi-hazard risk analysis, can be used to produce evidence-based risk assessments incorporating different land-use planning directions, hazard mitigation and adaption strategies and risk acceptance/tolerance thresholds.Four challenges encountered by planning practitioners have been explored: Greenfield development with multiple hazards. Policy interventions (protect, avoid, reduce and accept) within an urban flood plain. Climate-change interventions and scenarios, land-use intensification settings and adaptation options in a coastal setting. A component of a Dynamic Adaptive Policy Pathway (DAPP) approach for a coastal settlement. The focus of this study was on the Auckland region and included four case studies to highlight the capability of RiskScape™. While content for these cases has been developed in collaboration with Auckland Council to provide applied and relevant examples, the outputs do not represent or consist of direction or recommendation for Auckland Council to implement, nor do they represent possible changes to policy settings, such as level of tolerable risk being considered by Auckland Council. These cases were selected as they are replicable and relevant across Aotearoa New Zealand and demonstrate the ways in which RiskScape™ can be used to support consultation, cost-benefit analysis, adaption options and, ultimately, decision-making.The results from these cases include: identification of hazards (none/one/multiple) in a future development area to inform further spatial planning. Flooding in an urban area with an output of a range of options showing how different adaptation options could reduce the risk by targeting specific high-risk areas, while still allowing for some development potential to be retained. In the coastal context, understanding that the impact on risk from climate change and intensification – the impact of retreat / no further intensification – could reduce the overall risk in an area to an acceptable level. Also, understanding with increased certainty when some residential dwellings can expect ongoing disruption to access due to coastal inundation, as well as the suitability of triggers in a DAPP process.

description: Detection of quantum features in mechanical systems at the nanoscale constitutes a challenging task, given the weak interaction with other elements and the available technics. Here we describe how the interaction between two monomodal transmission-line resonators (TLRs) mediated by vibrations of a nano-electromechanical oscillator can be described. This scheme is then employed for quantum non-demolition detection of the number of phonons in the nano-electromechanical oscillator through a direct current measurement in the output of one of the TLRs. For that to be possible an undepleted field inside one of the TLR works as a amplifier for the interaction between the mechanical resonator and the remaining TLR. We also show how how the non-classical nature of this system can be used for generation of tripartite entanglement and conditioned mechanical coherent superposition states, which may be further explored for detection processes.

description: We investigate the performance of quantum fisher information under the Unruh-Hawking effect, where one of the observers (eg, Rob) is uniformly accelerated with respect to other partners. In the context of relativistic quantum information theory, we demonstrate that quantum fisher information, as an important measure of the information content of quantum states, has a rich and subtle physical structure comparing with entanglement or Bell nonlocality. In this work, we mainly focus on the parameterized (and arbitrary) pure two-qubit states, where the weight parameter $θ$ and phase parameter $ϕ$ are naturally introduced. Intriguingly, we prove that $\mathcal{F}_θ$ keeps unchanged for both scalar and Dirac fields. Meanwhile, we observe that $\mathcal{F}_ϕ$ decreases with the increase of acceleration $r$ but remains finite in the limit of infinite acceleration. More importantly, our results show that the symmetry of $\mathcal{F}_ϕ$ (with respect to $θ=π/4$) has been broken by the influence of Unruh effect for both cases.

title: Explaining timescales associated with jet stream variability

Publisher: name: University of Reading

description: Extreme weather events are often the result of slow-moving, large-scale wave patterns. Greater understanding of these large-scale modes of variability would allow us to anticipate how quasi-stationary modes might depend on changes to the background state in future climate. In this thesis the Empirical Normal Mode (ENM) technique, a technique for extracting dynamical modes of variability from atmospheric timeseries data, is utilised to examine the dependence of mode structure and frequency on jet latitude. The ENM methodology is extended to include the lower troposphere spanned by isentropic surfaces that can intersect the ground. This involves careful accounting of the terms in large amplitude pseudomomentum and pseudoenergy associated with this region of the atmosphere - terms that contribute to the ”boundary wave activity” in the limit of small amplitude. In the third chapter, the implementation of the technique itself is validated by testing the characteristic ‘intrinsic’ phase speed of the ENMs against an empirical phase speed derived from the modes’ principal component timeseries, using a set of idealised model experiments simulated using the Reading IGCM2.2. It is found that the phase speed matching conditions are met for the dominant freely propagating baroclinic modes, validating the approach to the calculation of wave activity and some approximations used in deriving relevant wave activity norms. In the fourth chapter, a new series of idealised experiments are devised that possess a jetstream with controllable latitude such that the change in behaviour of the modes of variability with a shift in jet latitude may be examined. The initial and relaxation temperature field in thermal wind balance with a prescribed zonal wind field with jet latitudes ranging from ∼ 40° to ∼ 65° is found, and a sloping tropopause is added in order to maintain baroclinicity. Subsequently, in the fifth chapter, the ENM structures of these experiments are found, and the change in the phase speed of the modes as the jet latitude changes is explored. A quasi-stationary branch of modes is identified which is associated with the most perturbation energy (for each zonal wavenumber) and therefore can propagate most strongly westwards against the background state westerly flow. As the jet is shifted polewards, the wavelength of the most energetic modes remains approximately the same, but they shift to lower zonal wavenumbers due to reduction in the latitude circle circumference.

description: The spiral host galaxy of GRB 060505 at z=0.089 was the site of a puzzling long duration burst without an accompanying supernova. Studies of the burst environment by Thöne et al. (2008) suggested that this GRB came from the collapse of a massive star and that the GRB site was a region with properties different from the rest of the galaxy. We reobserved the galaxy in high spatial resolution using the VIMOS integral-field unit (IFU) at the VLT with a spaxel size of 0.67 arcsec. Furthermore, we use long slit high resolution data from HIRES/Keck at two different slit positions covering the GRB site, the center of the galaxy and an HII region next to the GRB region. We compare the properties of different HII regions in the galaxy with the GRB site and study the global and local kinematic properties of this galaxy. The resolved data show that the GRB site has the lowest metallicity in the galaxy with around 1/3 Z_solar, but its specific SFR (SSFR) of 7.4 M_solar/yr/L/L* and age (determined by the Halpha EW) are similar to other HII regions in the host. The galaxy shows a gradient in metallicity and SSFR from the bulge to the outskirts as it is common for spiral galaxies. This gives further support to the theory that GRBs prefer regions of higher star-formation and lower metallicity, which, in S-type galaxies, are more easily found in the spiral arms than in the centre. Kinematic measurements of the galaxy do not show evidence for large perturbations but a minor merger in the past cannot be excluded. This study confirms the collapsar origin of GRB060505 but reveals that the properties of the HII region surrounding the GRB were not unique to that galaxy. Spatially resolved observations are key to know the implications and interpretations of unresolved GRB hosts observations at higher redshifts.

description: We calculate the differential conductance as a function of temperature and bias voltage, $G(T,V)$, through Au monoatomic chains with a substitutional Co atom as a magnetic impurity, connected to a four-fold symmetric lead. The system was recently proposed as a possible scenario for observation of the overscreened Kondo physics. Stretching the chain, the system could be tuned through a quantum critical point (QCP) with three different regimes, overscreened, underscreened and non Kondo phases. We present calculations of the impurity spectral function by using the numerical renormalization group (NRG) for the three different regimes characterizing the QCP. Non trivial behaviour of the spectral function is reported near the QCP. Comparison with results using the non crossing approximation (NCA), shows that the latter is reliable in the overscreened regime, when the anisotropy is larger than the Kondo temperature. For these parameters, which correspond to realistic previous estimates, $G(T,V)$ calculated within NCA exhibits clear signatures of the non-Fermi liquid behaviour within the overscreened regime.

description: Nano- and micromagnetic materials have been extensively employed in micro-functional devices. However, measuring small-scale mechanical and magnetomechanical properties is challenging, which restricts the design of new products and the performance of smart devices. A new magnetomechanical nanoindentation technique is developed and tested on a nickel single crystal in the absence and presence of a saturated magnetic field. Small-scale parameters such as Young's modulus, indentation hardness, and plastic index are dependent on the applied magnetic field, which differ greatly from their macroscale counterparts. Possible mechanisms that induced 31% increase in modulus and 7% reduction in hardness (i.e., the flexomagnetic effect and the interaction between dislocations andmagnetic field, respectively) are analyzed and discussed. Results could be useful in the microminiaturization of applications, such as tunable mechanical resonators and magnetic field sensors.
