Tensione sul limite di massa delle stelle di neutroni
Creators: Maura Sandri
Publisher: name: Media Inaf
Year: 2021

Le onde gravitazionali rilevate nei due eventi Gw 170817 e Gw 190814 hanno fornito informazioni contraddittorie riguardo al limite di massa delle stelle di neutroni, creando tensione e incertezza nella comunità scientifica. Uno studio presentato su ApJ Letters mostra che tale tensione può essere facilmente rimossa nel caso in cui la secondaria in Gw 190814 fosse un buco nero e non una stella di neutroni. Ne parliamo con uno degli autori, l’astrofisico Luciano Rezzolla

description: Although the frustrated spin chain (zigzag chain) is a Drosophila of frustrated magnetism, the understanding of a pair of coupled zigzag chains (frustrated spin ladder) in a magnetic field is incomplete. We address this problem through nuclear magnetic resonance (NMR) experiments on $\text{BiCu}_2\text{PO}_6$ in magnetic fields up to 45 T, revealing a field-induced spiral magnetic structure. Conjointly, we present advanced numerical calculations showing that even moderate rung coupling dramatically simplifies the phase diagram below half-saturation magnetization by stabilizing a field-induced chiral phase. Surprisingly for a one-dimensional model, this phase and its response to Dzyaloshinskii-Moriya (DM) interactions adhere to classical expectations. While explaining the behavior at the highest accessible magnetic fields, our results imply a different origin for the solitonic phases occurring at lower fields in $\text{BiCu}_2\text{PO}_6$. An exciting possibility is that the known, DM-mediated coupling between chirality and crystal lattice gives rise to a new kind of spin-Peierls instability.

description: In this paper we continue the study, started in [1], of the operatorial formulation of classical mechanics given by Koopman and von Neumann (KvN) in the Thirties. In particular we show that the introduction of the KvN Hilbert space of complex and square integrable "wave functions" requires an enlargement of the set of the observables of ordinary classical mechanics. The possible role and the meaning of these extra observables is briefly indicated in this work. We also analyze the similarities and differences between non selective measurements and two-slit experiments in classical and quantum mechanics.

description: We consider the Cauchy problem for the integrable nonlocal nonlinear Schrödinger (NNLS) equation $iq_{t}(x,t)+q_{xx}(x,t)+2 q^{2}(x,t)\bar{q}(-x,t)=0, \, x\in\mathbb{R},\,t>0,$ with a step-like boundary values: $q(x,t)\to 0$ as $x\to-\infty$ and $q(x,t)\to A$ as $x\to\infty$ for all $t\geq0$, where $A>0$ is a constant. The long-time asymptotics of the solution $q(x,t)$ of this problem along the rays $x/t=C\ne 0$ is presented in \cite{RS2}. In the present paper, we extend the asymptotics into a region that is asymptotically closer to the ray $x=0$ than these rays with any nonzero constant $C$. We specify a one-parameter family of wedges in the $x,t$-plane, with curved boundaries, characterized by qualitatively different asymptotic behavior of $q(x,t)$, and present the main asymptotic terms for each wedge. Particularly, for wedges with $x<0$, we show that the solution decays as $t^{p}\sqrt{\ln t}$ with $p<0$ depending on the wedge. For wedges with $x>0$, we show that the asymptotics has an oscillating nature, with the phase functions specific for each wedge and depending on a slow variable parametrizing the wedges. The main tool used in this work is an adaptation of the nonlinear steepest decent method to the case when the stationary phase point of the phase function in the jump of the associated Riemann-Hilbert problem merges with a point which is singular for the corresponding spectral functions.

description: Different string theories in twistor space have recently been proposed for describing ${\cal N}=4$ super-Yang-Mills. In this paper, my Strings 2003 talk is reviewed in which a string theory in $(x,θ)$ space was constructed for self-dual ${\cal N}=4$ super-Yang-Mills. It is hoped that these results will be useful for understanding the twistor-string proposals and their possible relation with the pure spinor formalism of the $d=10$ superstring.

Centrality fluctuations and decorrelations in heavy-ion collisions

description: The centrality or the number of initial-state sources $V$ of the system produced in heavy ion collision is a concept that is not uniquely defined and subject to significant theoretical and experimental uncertainties. We argue that a more robust connection between the initial-state sources with final-state multiplicity could be established from the event-by-event multiplicity correlation between two subevents separated in pseudorapidity, $N_a$ vs $N_b$. This correlation is sensitive to two main types of centrality fluctuations (CF): 1) particle production for each source $p(n)$ which smears the relation between $V$ and $N_a$ used for experimental centrality, and 2) decorrelations between the sources in the two subevents $V_b$ and $V_a$. The CF is analyzed in terms of cumulants of $V_b$ and $N_b$ as a function of $N_a$, i.e. experimental centrality is defined with $N_a$. We found that the mean values $\langle V_b\rangle_{N_a}$ and $\langle N_b\rangle_{N_a}$ increase linearly with $N_a$ in mid-central collisions, but flatten out in ultra-central collisions. Such non-linear behavior is sensitive to the centrality resolution of $N_a$. In the presence of centrality decorrelations, the scaled variances $\langle(δV_b)^2\rangle/\langle V_b\rangle$ and $\langle(δN_b)^2\rangle/\langle N_b\rangle$ are found to decrease linearly with $N_a$ in mid-central collisions, while the $p(n)$ leads to another sharp decrease in the ultra-central region. The higher-order cumulants of $V_b$ and $N_b$ show interesting but rather complex behaviors which deserve further studies. Our results suggest that one can use the cumulants of the two-dimensional multiplicity correlation, especially the mean and variance, to constrain the particle production mechanism as well as the longitudinal fluctuations of the initial-state sources.

description: Photons offer the potential to carry large amounts of information in their spectral, spatial, and polarisation degrees of freedom. While state-of-the-art classical communication systems routinely aim to maximize this information-carrying capacity via wavelength and spatial-mode division multiplexing, quantum systems based on multi-mode entanglement usually suffer from low state quality, long measurement times, and limited encoding capacity. At the same time, entanglement certification methods often rely on assumptions that compromise security. Here we show the certification of photonic high-dimensional entanglement in the transverse position-momentum degree-of-freedom with a record quality, measurement speed, and entanglement dimensionality, without making any assumptions about the state or channels. Using a tailored macro-pixel basis, precise spatial-mode measurements, and a modified entanglement witness, we demonstrate state fidelities of up to 94.4% in a 19-dimensional state-space, entanglement in up to 55 local dimensions, and an entanglement-of-formation of up to 4 ebits. Furthermore, our measurement times show an improvement of more than two orders of magnitude over previous state-of-the-art demonstrations. Our results pave the way for noise-robust quantum networks that saturate the information-carrying capacity of single photons.

description: Technological change and innovation are vitally important, especially for high-tech companies. However, factors influencing their future research and development (R&D) trends are both complicated and various, leading it a quite difficult task to make technology tracing for high-tech companies. To this end, in this paper, we develop a novel data-driven solution, i.e., Deep Technology Forecasting (DTF) framework, to automatically find the most possible technology directions customized to each high-tech company. Specially, DTF consists of three components: Potential Competitor Recognition (PCR), Collaborative Technology Recognition (CTR), and Deep Technology Tracing (DTT) neural network. For one thing, PCR and CTR aim to capture competitive relations among enterprises and collaborative relations among technologies, respectively. For another, DTT is designed for modeling dynamic interactions between companies and technologies with the above relations involved. Finally, we evaluate our DTF framework on real-world patent data, and the experimental results clearly prove that DTF can precisely help to prospect future technology emphasis of companies by exploiting hybrid factors.

description: Most of the existing question answering models can be largely compiled into two categories: i) open domain question answering models that answer generic questions and use large-scale knowledge base along with the targeted web-corpus retrieval and ii) closed domain question answering models that address focused questioning area and use complex deep learning models. Both the above models derive answers through textual comprehension methods. Due to their inability to capture the pedagogical meaning of textual content, these models are not appropriately suited to the educational field for pedagogy. In this paper, we propose an on-the-fly conceptual network model that incorporates educational semantics. The proposed model preserves correlations between conceptual entities by applying intelligent indexing algorithms on the concept network so as to improve answer generation. This model can be utilized for building interactive conversational agents for aiding classroom learning.

description: Data from the AMANDA-B10 detector taken during the austral winter of 1997 have been searched for a diffuse flux of high energy extraterrestrial muon-neutrinos, as predicted from, e.g., the sum of all active galaxies in the universe. This search yielded no excess events above those expected from the background atmospheric neutrinos, leading to upper limits on the extraterrestrial neutrino flux. For an assumed E^-2 spectrum, a 90% classical confidence level upper limit has been placed at a level E^2 Phi(E) = 8.4 x 10^-7 GeV cm^-2 s^-1 sr^-1 (for a predominant neutrino energy range 6-1000 TeV) which is the most restrictive bound placed by any neutrino detector. When specific predicted spectral forms are considered, it is found that some are excluded.

description: Brewe, Bruun, and Bearden first applied network analysis to understand patterns of incorrect conceptual physics reasoning in multiple-choice instruments introducing the Module Analysis for Multiple-Choice Responses (MAMCR) algorithm. Wells {\it et al.} proposed an extension to the algorithm which allowed the analysis of large datasets called Modified Module Analysis (MMA). This method analyzed the network structure of the correlation matrix of the responses to a multiple-choice instrument. Both MAMCR and MMA could only be applied to networks of incorrect responses. In this study, an extension of MMA is explored which allows the analysis of networks involving both correct and incorrect responses. The extension analyzes the network structure of the partial correlation matrix instead of the correlation matrix. The new algorithm, called MMA-P, was applied to the FCI and recovered much of the structure identified by MMA. The algorithm also identified sets of correct answers requiring similar physical reasoning reported in previous studies. Beyond groups of all correct and all incorrect responses, some groups of responses which mixed correct and incorrect responses were also identified. Some of these mixed response groups were produced when a correct response was selected for incorrect reasons; some of the groups helped to explain the gender unfairness previously reported for the FCI.
Flow Formations : Reimagining and regenerating the Salish Creek water network

description: This graduate project examines the interdependence of the global water crisis, freshwater biodiversity loss, and the environmental impact of golf courses, which pose significant risks to surface and groundwater quality. It highlights the critical role of freshwater ecosystems in sustaining biodiversity and human welfare, particularly under the stress of the global water demand and climate crises. Innovative solutions will be explored to reimagine the University Golf Course at the University of British Columbia into a multifunctional sustainable landscape that enhances urban biodiversity and resilience. By integrating permaculture and regenerative design principles, the proposal seeks to create dynamic, adaptable landscapes that serve as riparian buffers, support freshwater biodiversity, and promote a balanced hydrological cycle. The re-envisioned design focuses on creating interconnected habitats and natural filtration systems to address critical environmental challenges while maintaining the recreational value of the golf course, thereby fostering a symbiotic relationship with ecosystems in the adjacent freshwater wetlands and creeks in the Pacific Spirit Regional Park Area.

description: Pivotal within quantum physics, the concept of quantum incompatibility is generally related to algebraic aspects of the formalism, such as commutation relations and unbiasedness of bases. Recently, the concept was identified as a resource in tasks involving quantum state discrimination and quantum programmability. Here we link quantum incompatibility with the amount of information that can be extracted from a system upon successive measurements of noncommuting observables, a scenario related to communication tasks. This approach leads us to characterize incompatibility as a resource encoded in a physical context, which involves both the quantum state and observables. Moreover, starting with a measure of context incompatibility we derive a measurement-incompatibility quantifier that is easily computable, admits a geometrical interpretation, and is maximum only if the eigenbases of the involved observables are mutually unbiased.

Our proof is non constructive: it uses counting results from subgroup growth theory and the strong approximation theorem to show that such manifolds exist.

description: Research in computational linguistics has made successful attempts at modelling word meaning at scale, but much remains to be done to put these computational models to the test of historical scholarship (see e.g. Beelen et al. 2021). More importantly, a lot of computational research looks at texts in a historical vacuum, 'synchronically', as linguists would say. In Living with Machines, an interdisciplinary research project that rethinks the impact of technology on the lives of ordinary people during the Industrial Revolution, we decided to address a fundamental question: what did people mean by ‘machine’ and how has this meaning changed over time? This paper outlines how a simple research question like 'what was a machine?' can provide an opportunity to engage the public with our work while also generating data for analysis and new avenues of research in a radically collaborative way.

description: We derive effective actions for SU(2) Polyakov loops using inverse Monte Carlo techniques. In a first approach, we determine the effective couplings by requiring that the effective ensemble reproduces the single-site distribution of the Polyakov loops. The latter is flat below the critical temperature implying that the (untraced) Polyakov loop is distributed uniformly over its target space, the SU(2) group manifold. This allows for an analytic determination of the Binder cumulant and the distribution of the mean-field, which turns out to be approximately Gaussian. In a second approach, we employ novel lattice Schwinger-Dyson equations which reflect the SU(2) x SU(2) invariance of the functional Haar measure. Expanding the effective action in terms of SU(2) group characters makes the numerics sufficiently stable so that we are able to extract a total number of 14 couplings. The resulting action is short-ranged and reproduces the Yang-Mills correlators very well.

The Problems of NATO's R2P Implementation in Libya: Has the international Community Learnt its Lesson?

description: The international community’s speedy and decisive response to Gaddafi’s brutal oppression of innocent civilians raised new optimism for effective cooperation in humanitarian protection. However, as the situation unravelled it became clear that the way Responsibility to Protect (R2P) was implemented in Libya it appeared to have confirmed the long-standing suspicions of several non-western nations, who often perceived that the doctrine may be used as a pretext for regime change. The crisis also highlighted the problem of the United Nation’s decision making process regarding the use of coercive action and the consequences of not assuming post-intervention Responsibility to Rebuild in conflict prone areas. This thesis evaluates the problems associated with NATO’s military intervention in Libya to draw upon the lessons that can be learnt for the doctrine of R2P. In addition, it also analyses how the international community has moved forward with these lessons. By examining the ‘Responsibility while Protecting’ and the ‘Code of Conduct’, the thesis argues that even though these two initiatives were significant developments, the international community has not yet learnt their lessons regarding R2P’s proper implementation for humanitarian protection missions. The thesis concludes with the suggestion that the use of force in global politics can sometimes be necessary and hence, future military interventions for humanitarian protection must be based on the criterions provided by the Just War Tradition (as specified in the original ICISS report), which will strengthen and legitimise R2P’s present framework.

 Type SAM-A27712.
 Type locality Cave Rock, off Durban Bluff, KZN, South Africa, 20 m.
 Previous southern African record Type locality only.
 Material examined
SAM-A 27952, south of South Pier, Durban Bay, UCT Ecological Survey, sieving-grid of dredge, 12.1.1951, 3 fragments.
 Description
All fragments badly contracted, lacking anterior and extreme posterior ends, longest fragment 125 mm, width 8 mm, other fragments 20 mm and 60 mm. Colour greyish-brown, darker dorsally. Body wall covered with dense papillae, wheel papillae absent. Spicules of body wall as curved, terminally bifurcate rods, 26–94 µm (mean 62 µm), without central thickening; no deposits in radial muscles.
 Distribution Southern KZN, South Africa, shallow.
 Habitat Sand.
 Remarks
 The material at hand was left unidentified by Dr Cherbonnier when he reported on the southern African collections. Although anterior and posterior ends are missing there is no doubt that the material represents Chiridota durbanensis because of its size, colouration, dense papillose skin, absence of wheel papillae and radial muscle deposits and the presence, in the body wall, of only curved rods without a central thickening. This is a second record of the species described as? 100 mm long. If the three fragments here recorded belonged together, the species length will far exceed its recorded size. The rods are slightly larger than those recorded for the type, perhaps due to the larger size of the present material. Thandar (1996) remarked on two other congenerics, which either lack wheel papillae (Toxodora pacifica Ohshima, 1915 from Japan) or have poorly developed wheel papillae (T. ferruginea Verrill, 1882 from the eastern coast of USA) and supported the relegation of Toxodora to the synonymy of Chiridota.

description: Flavor SU(3) is used to constrain the coefficients of $\sinΔmt$ and $\cosΔmt$ in the time-dependent CP asymmetry of $B^0 \to η' K_S$. Correlated bounds in the $(S_{η' K}, C_{η' K})$ plane are derived, by using recent rate measurements of $B^0$ decays into $K^+ K^-, π^0π^0, π^0η, π^0η', ηη, ηη', η'η'$. Stringent bounds are obtained when assuming a single SU(3) singlet amplitude and when neglecting annihilation-type amplitudes.

Chemical freeze-out conditions from net-kaon fluctuations at RHIC

description: We compare the mean-over-variance ratio of the net-kaon distribution calculated within a state-of-the-art hadron resonance gas model to the latest experimental data from the Beam Energy Scan at RHIC by the STAR collaboration. Our analysis indicates that it is not possible to reproduce the experimental results using the freeze-out parameters from the existing combined fit of net-proton and net-electric charge mean-over-variance. The strange mesons need about 10-15 MeV higher temperatures than the light hadrons at the highest collision energies. In view of the recent lambda fluctuation measurements, we predict the net-lambda variance-over-mean at the light and strange chemical freeze-out parameters. We observe that the lambda fluctuations are sensitive to the difference in the freeze-out temperatures established in this analysis. Our results have implications for other phenomenological models in the field of relativistic heavy-ion collisions.

description: The use of speech data in nowcasting models is a new topic while the use of sentiment and emotion indicators from microblogs and internet platforms in nowcasting models has been discussed in the literature. The effect of the speech data of European Central Bank’s (ECB) officials on nowcasting Euro Area GDP is investigated in this paper. After performing a detailed descriptive analysis of the speech data, five emotion indicators are obtained as a result of the emotion analysis. The contribution of these emotion indicators is examined to a nowcasting model including indicators from the real sector and household/business surveys related to the Euro Area for the period of 1995:01-2019:12. The effects of emotion indicators on model are analysed root mean squared error (RMSE), impulse-response functions, variance decomposition analysis and revision analysis. Findings show that emotion indicators provide a decrease in RMSE of nowcasting model. It is found out that the shocks in the emotion indicators are significant on the GDP in the long term, and the emotion indicators are effective in explaining the variance of the forecast error variance of GDP. Revision analysis indicates that emotion indicators do not increase the revision of GDP nowcasts. As a result, it can be claimed that the emotion indicators obtained from the speeches of ECB officials have a noticeable effect on the nowcasting the Euro Area GDP.

description: Während sich der Perspektive sorgender Männer im Kontext der Care-Debatte verstärkt zugewendet wurde, stellt die Perspektive der Gepflegten auf Sorgearbeit im Pflegeheim eine Leerstelle dar. Der vorliegende Beitrag rückt anhand von zwei Fallbeispielen, Walter Probst (93) und Günther Schiffke (78), die Perspektive der pflegebedürftigen hochaltrigen Männer auf die geleistete Pflege und ihre Männlichkeitskonstruktionen in den Fokus. Dabei stehen das Verhältnis zwischen Pfleger*innen und Bewohner in der Pflegesituation sowie die Übernahme von Care-Aufgaben und die daraus resultierenden Männlichkeitskonstruktionen im Mittelpunkt. Während Walter Probst ,weibliche‘ und ,männliche’ Pflege verhandelt und die Aushandlung von Handlungsmacht in der Situation der Körperpflege schildert, kann Günther Schiffke durch die Übernahme von Care-Arbeit ein Näheverhältnis zu den Pfleger*innen herstellen. Das Material zeigt zum einen das stereotype Verständnis und die Reproduktion von Männlichkeit(en) und Weiblichkeit(en) in der Pflege der Bewohner. Zum anderen wird sichtbar, wie die Person im Pflegeheim durch die Übernahme von Care-Aufgaben einen Wandel hin zu fürsorglichem Verhalten vollzieht und damit auch veränderte Männlichkeitskonstruktionen einhergehen.

description: Previously suggested correlations of BL Lac type objects with the arrival directions of the ultra-high-energy cosmic ray primaries are tested by making use of the HiRes stereoscopic data. The results of the study support the conclusion that BL Lacs may be the cosmic ray sources and suggest the presence of a small (a few percent) fraction of neutral primaries at E>10^{19} eV.
