description: Understanding of unconventional superconductivity is crucial for engineering materials with specific order parameters or elevated superconducting transition temperatures. However, for many materials, the pairing mechanism and symmetry of the order parameter remain unclear: reliable and efficient methods of predicting the order parameter and its response to tuning parameters are lacking. Here, we investigate the response of superconductivity in Sr$_2$RuO$_4$ to structural distortions via the random phase approximation (RPA) and functional renormalization group (FRG), starting from realistic models of the electronic structure. Our results suggest that RPA misses the interplay of competing fluctuation channels. FRG reproduces key experimental findings. We predict a magic octahedral rotation angle, maximizing the superconducting $T_c$ and a dominant $d_{x^2-y^2}$ pairing symmetry. To enable experimental verification, we provide calculations of the phase-referenced Bogoliubov Quasiparticle Interference imaging. Our work demonstrates a designer approach to tuning unconventional superconductivity with relevance and applicability for a wide range of quantum materials.

On the Consistency of the Exact Renormalization Group Approach Applied to Gauge Theories in Algebraic Non-Covariant Gauges

description: We study a class of Wilsonian formulations of non-Abelian gauge theories in algebraic non-covariant gauges where the Wilsonian infrared cutoff $Λ$ is inserted as a mass term for the propagating fields. In this way the Ward-Takahashi identities are preserved to all scales. Nevertheless BRST-invariance in broken and the theory is gauge-dependent and unphysical at $Λ\neq0$. Then we discuss the infrared limit $Λ\to0$. We show that the singularities of the axial gauge choice are avoided in planar gauge and light-cone gauge. In addition the issue of infrared divergences is addressed in some explicit example. Finally the rectangular Wilson loop of size $2L\times 2T$ is evaluated at lowest order in perturbation theory and a non commutativity between the limits $Λ\to0$ and $T\to\infty$ is pointed out.

description: The exact solution of the one-dimensional Schrödinger equation with symmetric trigonometric double-well potential (DWP) is obtained via angular oblate spheroidal function. The results of stringent analytic calculation for the ground state splitting of ring-puckering vibration in the 1,3-dioxole (as an example of the case when the ground state tunneling doublet is well below the potential barrier top) and 2,3-dihydrofuran (as an example of the case when the ground state tunneling doublet is close to the potential barrier top) are compared with several variants of approximate semiclassical (WKB) ones. This enables us to verify the accuracy of various WKB formulas suggested in the literature: 1. ordinary WKB, i.e., the formula from the Landau and Lifshitz textbook; 2. Garg's formula; 3. instanton approach. We show that for the former case all three variants of WKB provide good accuracy while for the latter one they are very inaccurate. The results obtained provide a new theoretical tool for describing relevant experimental data on IR spectroscopy of ring-puckering vibrations.

Techno-aesthetic Thinking. Technicity and Symbolism in the Body

description: This paper investigates the reciprocal implications between aesthetics and technics, to show how technicity, as a cultural and symbolic attitude, is constitutively rooted in the aesthetic dimension of human experience. The analysis conducted aims to bring into focus the originarity of technicity in the development of the living body, understood in its inseparable connection with the mind, as junction between the sensible and the symbolic, the organic and the cultural, the perceptive and the expressive. I address this question through a parallel analysis of Simondon’s groundbreaking reflection on technics and the less explored account of technics in Merleau-Ponty’s philosophy. If the latter inscribes our attitude towards technics in the motricity and symbolism inherent to the living body, the former ascribes to aesthetics a form of thinking, thus playing a fundamental role in our relationship to the technical dimension. Despite the differences in their approach to technics, I combine their theoretical perspectives to encompass their internal limits and to outline possible convergences.

description: Interferometric tests of a f/1.2 2.5-m diameter liquid mirror show RMS surface deviations about wave/20 and Strehl ratios of order 0.6, showing that it is diffraction limited. The mirror is certainly better than implied by the data because of aberrations introduced by the auxiliary testing optics. We have made detailed studies of the scattered light of the mirror. We have studied the behavior of the mirror under external perturbations. With this article we have reached an important milestone since we now have a good understanding of liquid mirrors.

description: Graph encoder embedding, a recent technique for graph data, offers speed and scalability in producing vertex-level representations from binary graphs. In this paper, we extend the applicability of this method to a general graph model, which includes weighted graphs, distance matrices, and kernel matrices. We prove that the encoder embedding satisfies the law of large numbers and the central limit theorem on a per-observation basis. Under certain condition, it achieves asymptotic normality on a per-class basis, enabling optimal classification through discriminant analysis. These theoretical findings are validated through a series of experiments involving weighted graphs, as well as text and image data transformed into general graph representations using appropriate distance metrics.

description: We investigate the possibility of inflation with models of antisymmetric tensor field having minimal and nonminimal couplings to gravity. Although the minimal model does not support inflation, the nonminimal models, through the introduction of a nonminimal coupling to gravity, can give rise to stable de-Sitter solutions with a bound on the coupling parameters. The values of field and coupling parameters are sub-planckian. Slow roll analysis is performed and slow-roll parameters are defined which can give the required number of e-folds for sufficient inflation. Stability analysis has been performed for perturbations to antisymmetric field while keeping the metric unperturbed, and it is found that only the sub-horizon modes are free of ghost instability for de-Sitter space.

description: The security of control systems under sensor attacks is investigated. Redundant observability is introduced, explaining existing security notions including the security index, attack detectability, and observability under attacks. Equivalent conditions between redundant observability and existing notions are presented. Based on a bank of partial observers utilizing Kalman decomposition and a decoder exploiting redundancy, an estimator design algorithm is proposed enhancing the resilience of control systems. This scheme substantially improves computational efficiency utilizing far less memory.

description: We present new sets of fragmentation functions for charged pions and kaons, both at leading and next-to-leading order. They are fitted to data on inclusive charged-hadron production in $e^+e^-$ annihilation taken by TPC at PEP ($\sqrt s=29$~GeV) and to similar data by ALEPH at LEP, who discriminated between events with charm, bottom, and light- flavour fragmentation in their charged-hadron sample. We treat all partons independently and to properly incorporate the charm and bottom thresholds. Due to the sizeable energy gap between PEP and LEP, we are sensitive to the scaling violation in the fragmentation process, which allows us to extract a value for the asymptotic scale parameter of QCD, $Λ$. Recent data on inclusive charged-hadron production in tagged three-jet events by OPAL and similar data for longitudinal electron polarization by ALEPH allow us to pin down the gluon fragmentation functions. Our new fragmentation functions lead to an excellent description of a multitude of other $e^+e^-$ data on inclusive charged-hadron production, ranging from $\sqrt s=5.2$~GeV to LEP energy. In addition, they agree nicely with the transverse-momentum spectra of single charged hadrons measured by H1 and ZEUS in photoproduction at the $ep$ collider HERA, which represents a nontrivial check of the factorization theorem of the QCD-improved parton model.

description: In this paper we present novel methodology for automatic anomaly and switch event filtering to improve load estimation in power grid systems. By leveraging unsupervised methods with supervised optimization, our approach prioritizes interpretability while ensuring robust and generalizable performance on unseen data. Through experimentation, a combination of binary segmentation for change point detection and statistical process control for anomaly detection emerges as the most effective strategy, specifically when ensembled in a novel sequential manner. Results indicate the clear wasted potential when filtering is not applied. The automatic load estimation is also fairly accurate, with approximately 90% of estimates falling within a 10% error margin, with only a single significant failure in both the minimum and maximum load estimates across 60 measurements in the test set. Our methodology's interpretability makes it particularly suitable for critical infrastructure planning, thereby enhancing decision-making processes.

description: The Ultra-relativistic Quantum Molecular Dynamics model (UrQMD) is used to study global observables in central reactions of Au+Au at $\sqrt{s}=200$ AGeV (RHIC). Strong stopping governed by massive particle production is predicted if secondary interactions are taken into account. The underlying string dynamics and the early hadronic decoupling implies only small transverse expansion rates. However, rescattering with mesons is found to act as a source of pressure leading to additional flow of baryons and kaons, while cooling down pions.

The complexes have been characterized by elemental analyses, decomposition temperature, molar conductance, magnetic susceptibility, thermogravimetric studies, FT-IR, UV-vis, 1H NMR, 13C NMR, and FAB mass spectral studies. The thermal decomposition processes of one complex, cis-[MoO2(iso-bumphp)(8-hq)(H2O)] has been discussed with the evaluation of the order of reaction (n) and the activation energy (Ea) calculated from the thermogravimetric (TG) curve. Antibacterial study of one of the synthesized complexes at various dilutions has also been carried in comparison with the ligands and metal precursor using ampicillin as a standard drug. Gaussian09 software package was employed to carry out the theoretical study using density functional theory DFT/B3LYP level of theory under LANL2MB (for Mo)/6-311 + G (for non-metallic elements) basis set for one of the complexes, cis-[MoO2(bmphp)(8-hq)(H2O)]. Based on experimental and theoretical data, suitable pseudo pentagonal bipyramidal structures have been proposed for this class of metal complexes.

description: The Onion is a 1995 video performance by Marina Abramović. The essay aims at analyzing some central themes of the artist’s path, taking this work as reference text. First of all, by including the artist in the process of dissolution of beauty marking the art of the Twentieth century and regarding performance art as one of the outcomes of this process inaugurated by the avant-gardes. Secondly, by showing the link between the political dimension (in this particular case, the war in Yugoslavia in the 1990s) and an existential reflection focused on the role of the artist and the woman in the contemporary world.

description: Positron emission tomography (PET) is a well-established functional imaging technique for diagnosing brain disorders. However, PET's high costs and radiation exposure limit its widespread use. In contrast, magnetic resonance imaging (MRI) does not have these limitations. Although it also captures neurodegenerative changes, MRI is a less sensitive diagnostic tool than PET. To close this gap, we aim to generate synthetic PET from MRI. Herewith, we introduce PASTA, a novel pathology-aware image translation framework based on conditional diffusion models. Compared to the state-of-the-art methods, PASTA excels in preserving both structural and pathological details in the target modality, which is achieved through its highly interactive dual-arm architecture and multi-modal condition integration. A cycle exchange consistency and volumetric generation strategy elevate PASTA's capability to produce high-quality 3D PET scans. Our qualitative and quantitative results confirm that the synthesized PET scans from PASTA not only reach the best quantitative scores but also preserve the pathology correctly. For Alzheimer's classification, the performance of synthesized scans improves over MRI by 4%, almost reaching the performance of actual PET. Code is available at https://github.com/ai-med/PASTA.

description: We study SU(N) fermions in the limit of infinite on-site repulsion between all species. We focus on states in which every pair of consecutive fermions carries a different spin flavor. Since the particle order cannot be changed (because of the infinite on-site repulsion) and contiguous fermions have a different spin flavor, we refer to the corresponding constrained model as the model of distinguishable quantum particles. We introduce an exact numerical method to calculate equilibrium one-body correlations of distinguishable quantum particles based on a mapping onto noninteracting spinless fermions. In contrast to most many-body systems in one dimension, which usually exhibit either power-law or exponential decay of off-diagonal one-body correlations with distance, distinguishable quantum particles exhibit a Gaussian decay of one-body correlations in the ground state, while finite-temperature correlations are well described by stretched exponential decay.

Double Neutron Star Systems and Natal Neutron Star Kicks

Publisher: name: arXiv
Year: 1997
Subjects: subject: Astrophysics (astro-ph)

description: We study the four double neutron star systems found in the Galactic disk in terms of the orbital characteristics of their immediate progenitors and the natal kicks imparted to neutron stars. Analysis of the effect of the second supernova explosion on the orbital dynamics, combined with recent results from simulations of rapid accretion onto neutron stars lead us to conclude that the observed systems could not have been formed had the explosion been symmetric. Their formation becomes possible if kicks are imparted to the radio-pulsar companions at birth. We identify the constraints imposed on the immediate progenitors of the observed double neutron stars and calculate the ranges within which their binary characteristics (orbital separations and masses of the exploding stars) are restricted. We also study the dependence of these limits on the magnitude of the kick velocity and the time elapsed since the second explosion. For each of the double neutron stars, we derive a minimum kick magnitude required for their formation, and for the two systems in close orbits we find it to exceed 200km/s. Lower limits are also set to the center-of-mass velocities of double neutron stars, and we find them to be consistent with the current proper motion observations.

description: Contemporary theatre allows for a script, a scenario, that is exclusively visual. If action is no longer supported by dialogue, this does not mean that it will disappear. It will undoubtedly return in gestural exchange and in a temporality that is expansive or contracted and condensed. Action becomes an opaque enigma. The interpretation of performative action is a journey that the spectator undertakes in a foreign country, where we are forced to learn a new language. It remains to be seen what the reaction and the work of interpretation of the spectator would be when confronted with an action knowingly deprived of any meaningful anchor or referent. Would it merely be confusion? Confusion and an interpretative effort that often comes to an end by a harsh defeat: the aesthetic of the performative represents a moment of rupture in the process of rethinking of the traditional relationship between artist and spectator.

description: Around 20 years ago, M. Van den Bergh introduced double Poisson brackets as operations on associative algebras inducing Poisson brackets under the representation functor. Weaker versions of these operations, called modified double Poisson brackets, were later introduced by S. Arthamonov in order to induce a Poisson bracket on moduli spaces of representations of the corresponding associative algebras. Moreover, he defined two operations that he conjectured to be modified double Poisson brackets. The first case of this conjecture was recently proved by M. Goncharov and V. Gubarev motivated by the theory of Rota-Baxter operators of nonzero weight. We settle the conjecture by realising the second case as part of a new family of modified double Poisson brackets. These are obtained from mixed double Poisson algebras, a new class of algebraic structures that are introduced and studied in the present work.

Doubt and Indifference: Threshold Conditions within the Work of Art
Creators: name: Benjamin, Andrew
Publisher: name: Aisthesis. Pratiche, linguaggi e saperi dell’estetico
Year: 2019

description: The project of this paper is part of a larger attempt to develop a philosophy of art. Integral to that project is the distinction between aesthetics and a philosophy of art. It is always possible to consider affect as an end in itself if what is at stake involves a series of psychological claims. Equally, it is possible to engage with such claims philosophically. However, there is no clear connection between either possibility and a philosophy of art. In the latter the presentation of affect is always located within images. Images are produced by the work of materials. Images have to be understood in terms of that production. They have a material presence. If there is a failure to insist on the complex materiality of art’s work as comprising a locus of philosophical inquiry, then any subsequent theory of the image is unable to contribute to the development of a genuine philosophy of art. Moreover, within the history of art images are informed form. The informing of form has two elements. Form is informed firstly by the history in which those images are located, and secondly by their capacity to be reworked. The latter can be understood as a futural coming-into-relation and thus the possibility that images and the elements from which they are comprised are able to have an afterlife. The afterlife is forms’ capacity to continue to be informed. It is this latter possibility which necessitates that hermeneutic concerns supplant aesthetic ones in the creation of a philosophy of art.

description: The Laser Interferometer Space Antenna (LISA) will detect gravitational-wave (GW) signals from merging supermassive black holes (BHs) with masses below $10^7$~M$_{\odot}$. It is thus of paramount importance to understand the orbital dynamics of these relatively light central BHs, which typically reside in disc-dominated galaxies, in order to produce reliable forecasts of merger rates. To this aim, realistic simulations probing BH dynamics in unequal-mass disc galaxy mergers, into and beyond the binary hardening stage, are performed by combining smooth particle hydrodynamics and direct $N$-body codes. The structural properties and orbits of the galaxies are chosen to be consistent with the results of galaxy formation simulations. Stellar and dark matter distributions are triaxial down to the central 100 pc of merger remnant. In all cases, a BH binary forms and hardens on time-scales of at most 100~Myr, coalescing on another few hundred Myr time-scale, depending on the characteristic density and orbital eccentricity. Overall, the sinking of the BH binary takes no more than $\sim$0.5~Gyr after the merger of the two galaxies is completed, but can be much faster for very plunging orbits. Comparing with previous numerical simulations following the decay of BHs in massive early-type galaxies at $z \sim 3$, we confirm that the characteristic density is the most crucial parameter determining the overall BH merging time-scale, despite the structural diversity of the host galaxies. Our results lay down the basis for robust forecasts of LISA event rates in the case of merging BHs.

Nuove frontiere di paternità: dal legame biologico a quello sociale nelle famiglie atipiche

description: This paper analyses the transformation of the social representation of fathers, with particular reference to the social parenthood, which arises from the debate on the paternity crisis. The origin of paternity is traced back to the psycho-pedagogical level, by comparing biological and social paternity. This way, they establish the primary elements behind the outlining of the process of paternal identity. Discussion about the father’s role allows us to overcome the opposing masculine and feminine parenting models that sustain the concept of the “paternity crisis”, approaching a model that looks at how the subject expresses his or her parenthood within the family and sociocultural context, beyond a perspective centered on gender stereotypes.

description: We propose a new U(1) gauge interaction in the bulk in higher dimensional spacetime, which transmits supersymmetry-breaking effects on the hidden brane to the observable our brane. We find that rather small gauge coupling constant of U(1)_{bulk}, $α_{bulk} \simeq 5 \times 10^{-4}$, is required for a successful phenomenology. This result implies the compactification length $L$ of the extra dimension to be $L^{-1} \simeq 2 \times 10^{15}GeV$ for (4+1)-dimensional spacetime. This large compactification length $L$ is a crucial ingredient to suppress unwanted flavor-changing neutral currents and hence our proposal is very consistent with the Randall-Sundrum brane-world scenario.

description: In the field of brain-computer interfaces (BCIs), the potential for leveraging deep learning techniques for representing electroencephalogram (EEG) signals has gained substantial interest. This review synthesizes empirical findings from a collection of articles using deep representation learning techniques for BCI decoding, to provide a comprehensive analysis of the current state-of-the-art. Each article was scrutinized based on three criteria: (1) the deep representation learning technique employed, (2) the underlying motivation for its utilization, and (3) the approaches adopted for characterizing the learned representations. Among the 81 articles finally reviewed in depth, our analysis reveals a predominance of 31 articles using autoencoders. We identified 13 studies employing self-supervised learning (SSL) techniques, among which ten were published in 2022 or later, attesting to the relative youth of the field. However, at the time being, none of these have led to standard foundation models that are picked up by the BCI community. Likewise, only a few studies have introspected their learned representations. We observed that the motivation in most studies for using representation learning techniques is for solving transfer learning tasks, but we also found more specific motivations such as to learn robustness or invariances, as an algorithmic bridge, or finally to uncover the structure of the data. Given the potential of foundation models to effectively tackle these challenges, we advocate for a continued dedication to the advancement of foundation models specifically designed for EEG signal decoding by using SSL techniques. We also underline the imperative of establishing specialized benchmarks and datasets to facilitate the development and continuous improvement of such foundation models.

Sul padre e il disagio della civiltà, sulla funzione paterna, sulla paternità nella disabilità
Creators: name: Fratini, Tommaso

description: The article intends to insert itself into the debate on the current crisis of the paternal figure and the sense of fatherhood, through the lens of civilization and its discontents. After a review of some functions of fatherhood, the experience of being a disabled father is examined. In a narcissistic society model in which great importance is attributed to the significance of power, the potential experience of impairment within the role of the father in disability invites us to reflect on the importance of an educational transmission of values that moves from depression and from depressive feelings as a starting point to support the children’s educational path in a personal search for their own autonomy, with an authentic and profound meaning, beyond the superficial myths of hedonism, homologation, and marketing.

description: The supersymmetric ``shining'' of free massive chiral superfields in extra dimensions from a distant source brane can trigger exponentially small supersymmetry breaking on our brane of order e^{-2 pi R}, where R is the radius of the extra dimensions. This supersymmetry breaking can be transmitted to the superpartners in a number of ways, for instance by gravity or via the standard model gauge interactions. The radius R can easily be stabilized at a size O(10) larger that the fundamental scale. The models are extremely simple, relying only on free, classical bulk dynamics to solve the hierarchy problem.

Dall’immagine di un padre di “seconda generazione”, mito e poetica come chiave interpretativa e “cura”
Creators: name: Ghirmai, Iohannes
Publisher: name: Rivista Italiana di Educazione Familiare
Year: 2018

description: Starting from elements deduced by our Ph.D. research, the essay is inspired by the personal idealisation of the father of a man belonging to a Eritrean “second generation”, who rescues his feelings idealising the few traces remained printed in his memories. The task of the article is to analyse some evolutional aspects of the paternal figure, resulting in a particular aspect known by some authors as “weakening”. This propocess is explained with the help of some myths, poetics, representations of the father and several theories. As pedagogical, therapeutic and hermeneutic elements of the relationship whith the father will be proposed some forms of canalization of the sensitivity: the Logos is replaced by mythical tales, fairy tales and movies.

Holographic Weyl anomaly in string theory

Subjects: subject: High Energy Physics - Theory (hep-th)

description: We compute the worldsheet sphere partition function of string theory on global AdS$_3$ with pure NS-NS flux. Because of an unfixed Möbius symmetry on the worldsheet, there is a cancellation of infinities and only a part of the answer is unambiguous. We show that it precisely reproduces the holographic Weyl anomaly and the ambiguous terms correspond to the possible counterterms of the boundary CFT.

Conflitto di coppia, reazioni amplificate e determinazioni interne cronicizzate

Year: 2018

description: Considering that it is ingenuous to imagine eliminating anger, fury and aggressive behavior, which are in any case important components of hereditary repertoire of the humankind, in managing couple’s conflicts it is preferable to focus on accentuations and amplifications and intervene to restore congruence. Borrowing the model of the life script from Transactional Analysis, this paper explores the relationships between over-sized reactions and internalized dispositions. The working hypothesis is that specific determinations originally taken to deal with stressful and traumatizing situations, once they internalized and became chronic, can influence the decoding of reality, for example by altering an/or amplifying the sensation of threat, as well as intensifying consequent defensive plans. In essence, numerous exaggerations and incongruities arebased on particular interpretations of the partner’s messages, which are wrongly amplified and/or distorted because they are deciphered as pressing invitations to implement orders and/or internal prescriptions.

description: An intergalactic magnetic field stronger than $3\times10^{-13}$~G would explain the lack of a bright, extended degree-scale, GeV-energy inverse Compton component in the gamma-ray spectra of TeV-blazars. A robustly predicted consequence of the presence of such a field is the existence of degree-scale GeV-energy gamma-ray halos -- gamma-ray bow ties -- about TeV-bright active galactic nuclei, corresponding to more than half of all radio galaxies. However, the emitting regions of these halos are confined to and aligned with the direction of the relativistic jets associated with gamma-ray sources. Based on the orientation of radio jets, we align and stack corresponding degree-scale gamma-ray images of isolated Fanaroff-Riley class I and II objects and exclude the existence of these halos at overwhelming confidence, limiting the intergalactic field strength to $<10^{-15}$~G for large-scale fields and progressively larger in the diffusive regime when the correlation length of the field becomes small in comparison to 1 Mpc. When combined with prior limits on the strength of the intergalactic magnetic field, this excludes a purely magnetic explanation for the absence of halos. Thus, it requires the existence of novel physical processes that preempt the creation of halos, e.g., the presence of beam-plasma instabilities in the intergalactic medium or a drastic cutoff of the very high energy spectrum of these sources.
