description: Trial wavefunctions that can be represented by summing over locally-coupled degrees of freedom are called tensor network states (TNSs); they have seemed difficult to construct for two-dimensional topological phases that possess protected gapless edge excitations. We show it can be done for chiral states of free fermions, using a Gaussian Grassmann integral, yielding $p_x \pm i p_y$ and Chern insulator states, in the sense that the fermionic excitations live in a topologically non-trivial bundle of the required type. We prove that any strictly short-range quadratic parent Hamiltonian for these states is gapless; the proof holds for a class of systems in any dimension of space. The proof also shows, quite generally, that sets of compactly-supported Wannier-type functions do not exist for band structures in this class. We construct further examples of TNSs that are analogs of fractional (including non-Abelian) quantum Hall phases; it is not known whether parent Hamiltonians for these are also gapless.

description: Tidal disruption events (TDEs) show a correlation between the UV to X-ray spectral index and the Eddington ratio, with non-thermal X-ray emission at the low Eddington ratio. We consider the corona surrounding the accretion disc as a non-thermal X-ray source. We construct a time-dependent and non-relativistic advective accretion disc-corona model for TDEs. The infalling debris is assumed to form a seed disc in time $t_c$, that evolves due to the mass gain from the infalling debris at the constant outer radius with a mass fallback rate $\dot{M}_{\rm fb}$ and the mass loss through accretion onto the black hole. The viscous stress in our model depends on gas ($P_g$) and total ($P_t$) pressures as $τ_{rϕ} \propto P_g^{1-μ} P_t^μ$, where $μ$ is a constant. We find that the mass accretion rate $\dot{M}_a$ evolves from Eddington to sub-Eddington accretion with a late-time evolution close to $t^{-5/3}$, where $t$ is the time. We find that the bolometric disc luminosity follows a late-time evolution close to $t^{-5/3}$. The ratio of total X-ray luminosity from corona to bolometric disc luminosity increases with $μ$ and increases at late times for $μ\neq 1$. We obtain the X-ray blackbody temperature of the disc that agrees with the temperature from X-ray observations ($\sim~10^5~{\rm K}$). We find the radiative efficiency of the disc increases with time and decreases for a disc when the corona is included. We have neglected the outflow, and our model is more applicable for near-to-sub-Eddington accretion and when $\dot{M}_{\rm fb}$ is sub-Eddington.

description: L’articolo riassume un contributo al dibattito su Ernesto Rossi economista, nell’ambito di un evento promosso dalla Fondazione Rossi-Salvemini e dall’Associazione Economia Civile nel febbraio 2022 (di cui si ricordano le finalità nell’Introduzione). Scopo principale è sottolineare le affinità di pensiero tra Ernesto Rossi e Paolo Sylos Labini nel contesto della lotta alla ‘miseria’, ovvero nella definizione di strumenti di politica economica atti a ridurre le disuguaglianze economiche e valorizzare i ‘servizi essenziali’ a cui Rossi dedica ampio spazio nel suo Abolire la miseria ([1946] 1977).

description: L’allievo e il mentore. Sono i ruoli intorno ai quali ruota il rapporto fra Giorgio Fuà ed Ernesto Rossi. Un rapporto nato all’alba del 1943, quando l’economista casertano, dal confino, inviò alle Nuove Edizioni Ivrea il manoscritto Il problema agrario. Giovane studioso, coinvolto da Adriano Olivetti nella sua prima avventura editoriale, Fuà lesse e commentò il saggio, non senza risparmiargli annotazioni critiche, per lo più apprezzate da Rossi. I due presero a scambiarsi lettere cui dal dopoguerra abbinarono un’assidua frequentazione, che condusse tra l’altro Fuà a essere cooptato da Rossi nell’Azienda per il Rilievo e l’Alienazione dei Residuati (ARAR) e, più tardi, Rossi a chiedere la collaborazione di Fuà – nel frattempo divenuto capo dell’Ufficio studi dell’ENI – per le sue indagini sull’industria petrolifera.

description: To solve the Dirac equation with the finite difference method, one has to face up to the spurious-state problem due to the fermion doubling problem when using the conventional central difference formula to calculate the first-order derivative on the equal interval lattices. This problem is resolved by replacing the central difference formula with the asymmetric difference formula, i.e., the backward or forward difference formula. To guarantee the hermitian of the Hamiltonian matrix, the backward and forward difference formula should be used alternatively according to the parity of the wavefunction. This provides a simple and efficient numerical prescription to solve various relativistic problems in the microscopic world.

description: One of the puzzles to have emerged from the Kepler and TESS missions is the existence of unexplained dips in the lightcurves of a small fraction of rapidly-rotating M dwarfs in young open clusters and star-forming regions. We present a theoretical investigation of one possible explanation - that these are caused by dust clouds trapped in the stellar magnetic fields. The depth and duration of the observed dips allow us to estimate directly the linear extent of the dust clouds and their distances from the rotation axis. The dips are found to be between 0.4-4.8%. We find that their distance is close to the co-rotation radius: the typical location for stable points where charged particles can be trapped in a stellar magnetosphere. We estimate the charge acquired by a dust particle due to collisions with the coronal gas and hence determine the maximum grain size that can be magnetically supported, the stopping distance due to gas drag and the timescale on which dust particles can diffuse out of a stable point. Using the observationally-derived magnetic field of the active M dwarf V374 Peg, we model the distribution of these dust clouds and produce synthetic light curves. We find that for 1 micron dust grains, the light curves have dips of 1% - 3% and can support masses of order of $10^{12}$kg. We conclude that magnetically-trapped dust clouds (potentially from residual disc accretion or tidally-disrupted planetesimal or cometary bodies) are capable of explaining the periodic dips in the Kepler and TESS data.

description: The lack of large-angle correlations in the observed microwave background temperature fluctuations persists in the final-year maps from WMAP and the first cosmological data release from Planck. We find a statistically robust and significant result: p-values for the missing correlations lying below 0.24 per cent (i.e. evidence at more than 3 sigma) for foreground cleaned maps, in complete agreement with previous analyses based upon earlier WMAP data. A conservative cut-sky analysis of the Planck HFI 100 GHz frequency band, the `cleanest CMB channel', returns a p-value as small as 0.03 per cent, based on the conservative mask defined by WMAP. These findings are in stark contrast to expectations from the inflationary Lambda cold dark matter model and still lack a convincing explanation. If this lack of large-angle correlations is a true feature of our Universe, and not just a statistical fluke, then the cosmological dipole must be considerably smaller than that predicted in the best-fitting model.

description: We consider renormalization of effective field theory interactions by discretizing the continuum on a tight-binding lattice. After studying the one-dimensional problem, we address s-wave collisions in three dimensions and relate the bare lattice coupling constants to the continuum coupling constants. Our method constitutes a very simple avenue for the systematic renormalization in effective field theory, and is especially useful as the number of interaction parameters increases.

Chemically Peculiar Stars in Integrated Light Stellar Population Models and Local Group Galaxies

Year: 2022
Subjects: subject: Astrophysics of Galaxies (astro-ph.GA)

description: Integrated-light models that incorporate common types of chemically peculiar (CP) stars are assembled using synthetic spectra. Selected spectral features encode significant age information for populations with ages $\sim$50 Myr $<$ age $< \sim$2 Gyr. Due to the alleviation of template mismatch, the inclusion of CP star features in model spectra improves the accuracy of recovered stellar population parameters, but we are not able to show that new or unique age information can be extracted from the weak CP features compared to continuum fitting and strong-feature strengths, at least at the present state of the art. An age-extraction routine that recovers 2- and 3-burst age structures is employed to analyze the spectra of local group galaxies. NGC 224 (M31) has a stellar population too old for the types of CP stars we examine. NGC 221 (M32) also shows no CP spectral features. It appears to contain a component at age $\sim$1 Gyr at 1% by mass in addition to its dominant 4.7 Gyr population. Unlike SDSS galaxy spectrum averages, NGC 205 (M110) contains no features due to HgMn stars. This excludes the age range associated with HgMn production, and its near-nuclear spectrum is best fit by a 68$\pm$2 Myr population superimposed on an older population with a 1.85$\pm$0.1 Gyr component. Both NGC 205 and NGC 221 have an ancient component whose mass is not easy to constrain given the overwhelming light-dominance of the younger populations.

description: Obiettivo del contributo, nel ripercorrerne gli studi negli anni del carcere, è di mostrare come Ernesto Rossi sia stato sino ad oggi un economista scarsamente riconosciuto: forse perché la sua figura di studioso è stata oscurata da altri aspetti della sua personalità o per la sua fama di irriverente “Giamburrasca dell’economia”, secondo l’affettuosa definizione di Piero Calamandrei, ma soprattutto perché la parte più ‘accademica’ del suo percorso di economista si è svolta – paradossalmente – proprio in carcere. Il suo epistolario si rivela, così, indispensabile per comprenderne e apprezzarne appieno la figura di studioso nel panorama del pensiero economico fra le due guerre mondiali.

description: A scoping review was undertaken to identify strategies which increase telephone accessibility for workers with hearing loss. The scoping review protocol outlined by the Joanna Brigg’s Institute was used. Terms relating to hearing loss, telephones, and management strategies were searched in CINAHL, MEDLINE, and Web of Science. An additional hand search was also conducted for two journals and two publications from consumer organisations as they were known to publish relevant articles. Inclusion and exclusion criteria were applied to the resulting 1086 texts. Strategies from the selected texts were organised into categories through thematic analyses. Study sample: Eighty-four texts were included in the review. The effective telephone strategies fall into the following categories: amplifying the telephone signal, reducing background noise, listening to the telephone through both ears, accessing text-based supports to understanding telephone speech, using Internet-based telephony, optimising mobile phones, improving telephone skills and communication strategies, and requesting accommodation in the workplace. Strategies exist by which the telephone can be made more accessible to workers with hearing loss. These have the potential to benefit both workers and their employers.
“Aquele Abraco”: Brazilian Protest Music in the Face of Repression

description: This paper explores the relationship between Brazilian popular music and the military dictatorship. By focusing on three singers Geraldo Vandré, Caetano Veloso, and Chico Buarque, the range of musicians’ experiences confronting authoritarianism is seen through their responses to censorship and persecution. Censorship played a large role in the repression of culture and media during the Brazilian military dictatorship. Analyzing the experiences of musical artists provides a glimpse into both how leftist voices spoke out against oppression and how the military attempted to suppress them. Through public music festivals, new mass mediums, and innovative lyricism, artists of Brazilian popular music fought official censors to attempt to maintain connection to and hope within their audiences. Studying these interactions is pertinent because it is important to look at the ways censoring art can impact the artists and audiences, and how censorship was used to hide human rights violations.

description: The combination of cyclin-dependent kinase 4/6 (CDK4/6) inhibitors and standard endocrine therapy (ET) in the adjuvant treatment of hormone receptor (HR)-positive/HER2-negative breast cancer (BC) has yielded conflicting results. We performed a pooled analysis of the adjuvant efficacy of CDK4/6 inhibitors by including data from the NATALEE trial, the most recent trial on this topic. We searched major databases and congress proceedings until 7 June 2023 to identify randomized controlled trials (RCT) comparing adjuvant CDK4/6 inhibitor plus ET combination versus ET in HR-positive/HER2-negative early-stage BC. Four RCTs involving a total of 17,749 patients were included. According to the pooled analysis of these four studies, significant improvement in invasive disease-free survival (iDFS) was observed with the addition of CDK4/6 inhibitors to standard ET (HzR: 0.81, 95% CI 0.67–0.97). IDFS benefit was irrespective from menopausal status, Ki-67 index, tumor grade, and previous chemotherapy. CDK4/6 inhibitors plus ET had a significant improvement in iDFS in stage 3 whereas there was a trend toward better iDFS in stage 2 (HzR for stage 3: 0.67, 95% CI 0.58–0.78; HzR for stage 2: 0.74, 95% CI 0.55–1.01). Addition of CDK4/6 inhibitors to standard ET in the adjuvant treatment of HR-positive/HER2-negative early-stage BC improves iDFS.

description: Volatiles, notably water, are key to the habitability of rocky planets. The presence of water in planetary material can be inferred from the atmospheric oxygen abundances of polluted white dwarfs, but this interpretation is often complex. We study the accretion process, and find that ices may sublimate and accrete before more refractory minerals reach the star. As a result, a white dwarf's relative photospheric abundances may vary with time during a single accretion event, and do not necessarily reflect the bulk composition of a pollutant. We offer two testable predictions for this hypothesis: 1. cooler stars will more often be inferred to have accreted wet pollutants, and 2. there will be rare occurrences of accretion events with inferred volatile levels far exceeding those of pristine comets. To observationally test these predictions, we statistically constrain the water content of white dwarf pollutants. We find that in the current sample, only three stars show statistically significant evidence of water at the 2$σ$ level, due to large typical uncertainties in atmospheric abundances and accretion states. In the future, an expanded sample of polluted white dwarfs with hydrogen-dominated atmospheres will allow for the corroboration of our theoretical predictions. Our work also shows the importance of interpreting pollutant compositions statistically, and emphasizes the requirement to reduce uncertainties on measured abundances to allow for statistically significant constraints on their water content.

description: Polluted white dwarfs serve as astrophysical mass spectrometers - their photospheric abundances are used to infer the composition of planetary objects that accrete onto them. We show that due to asymmetries in the accretion process, the composition of the material falling onto a star may vary with time during the accretion of a single planetary body. Consequently, the instantaneous photospheric abundances of white dwarfs do not necessarily reflect the bulk composition of their pollutants, especially when their diffusion timescales are short. In particular, we predict that when an asteroid with an iron core tidally disrupts around a white dwarf, a larger share of its mantle is ejected, and that the core/mantle fraction of the accreting material varies with time during the event. Crucially, this implies that the core fraction of differentiated pollutants cannot be determined for white dwarfs with short diffusion timescales, which sample only brief episodes of longer accretion processes. The observed population of polluted white dwarfs backs up the proposed theory. More white dwarfs have accreted material with high Fe/Ca than low Fe/Ca relative to stellar abundance ratios, indicating the ejection of mantle material. Additionally, we find tentative evidence that the accretion rate of iron decreases more rapidly than that of magnesium or calcium, hinting at variability of the accreted composition. Further corroboration of the proposed theory will come from the up-coming analysis of large samples of young white dwarfs.

description: This study introduces a back-propagation (BP) neural network model and a regression model for estimating the fracture fluid efficiency based on a data set consisting of 1261 staged and ramped simulation runs of tight gas reservoirs subjected to hydraulic fracturing treatment. Data were generated using a 3-D commercial simulator which is a versatile software portfolio that models many well configurations, proppant placement, and fracture geometries. The BP network inputs consist of shear rate/fracture conductivity ratio, the injection rate, reservoir permeability, formation closure stress, reservoir thickness, effective viscosity, and fracture height. The neural network model was able to generate satisfactory estimates of the fracture fluid efficiency for the training dataset, and for the blind testing data. An average error of approximately 2.5% was obtained for the training set, and an average error of 3% was obtained for the testing set. An empirical non-linear regression model has been constructed based on dimensionless groups derived by applying dimensional analysis to a set of variables consisting of the maximum fracture width, fracture length, fracture height, effective viscosity, shear rate/fracture conductivity ratio, reservoir thickness, injection rate, reservoir permeability, and formation closure stress. The average error for estimating the fluid efficiency using the non-linear regression empirical model was approximately 6.17%. Since the non-linear regression model has an explicit formulation, it is easier to apply than the neural network model. The empirical regression model estimates of the fluid efficiency appeared to be unbiased and were more precise than those estimates obtained using either the KGD or the PKN 2-D models. The introduced BP model and the non-linear regression model offer fast and inexpensive alternatives to the application of three-dimensional simulators for estimating the fluid efficiency.

The Standard Model of particle physics provides no explanation for its value, which could potentially vary. The wavelengths of stellar absorption lines depend on $α$, but are subject to systematic effects owing to astrophysical processes in stellar atmospheres. We measured precise line wavelengths using 17 stars, selected to have almost identical atmospheric properties to those of the Sun (solar twins), which reduces those systematic effects. We found that $α$ varies by $\lesssim$50 parts-per-billion (ppb) within 50 parsecs from Earth. Combining the results from all 17 stars provides an empirical, local reference for stellar measurements of $α$ with an ensemble precision of 12 ppb.

description: A scoping review was undertaken to identify strategies which increase telephone accessibility for workers with hearing loss. The scoping review protocol outlined by the Joanna Brigg’s Institute was used. Terms relating to hearing loss, telephones, and management strategies were searched in CINAHL, MEDLINE, and Web of Science. An additional hand search was also conducted for two journals and two publications from consumer organisations as they were known to publish relevant articles. Inclusion and exclusion criteria were applied to the resulting 1086 texts. Strategies from the selected texts were organised into categories through thematic analyses. Study sample: Eighty-four texts were included in the review. The effective telephone strategies fall into the following categories: amplifying the telephone signal, reducing background noise, listening to the telephone through both ears, accessing text-based supports to understanding telephone speech, using Internet-based telephony, optimising mobile phones, improving telephone skills and communication strategies, and requesting accommodation in the workplace. Strategies exist by which the telephone can be made more accessible to workers with hearing loss. These have the potential to benefit both workers and their employers.
A note on certain ergodicity coefficients

description: We investigate two ergodicity coefficients $ϕ_{\|\, \|}$ and $τ_{n-1}$, originally introduced to bound the subdominant eigenvalues of nonnegative matrices. The former has been generalized to complex matrices in recent years and several properties for such generalized version have been shown so far. We provide a further result concerning the limit of its powers. Then we propose a generalization of the second coefficient $τ_{n-1}$ and we show that, under mild conditions, it can be used to recast the eigenvector problem $Ax=x$ as a particular M-matrix linear system, whose coefficient matrix can be defined in terms of the entries of $A$. Such property turns out to generalize the two known equivalent formulations of the Pagerank centrality of a graph.

description: Objective: This study explored the feasibility of cortical automatic threshold estimation (CATE), a fully automated late auditory evoked potential (AEP) test, as an alternative to pure-tone audiometry for hearing threshold estimation for adults with dementia living in aged care. Design: A single group cross-sectional study was conducted. Participants’ dementia severity was determined through the Clinical Dementia Rating scale. Hearing thresholds were obtained for four audiometric frequencies in at least one ear by using both pure-tone audiometry and CATE. Study sample: Sixteen participants enrolled in the study, of which 14 completed at least one of the hearing tests. Twelve ears, from six participants, were included in the final correlation analysis. Results: Pearson correlation coefficients were significant between CATE and pure-tone audiometry for all frequencies: r2 = 0.52 (p = 0.008) for 500 Hz, r2 = 0.79 (p = 0.0001) for 1000 Hz, r2 = 0.71 (p = 0.0005) for 2000 Hz, and r2 = 0.92 (p < 0.0001) for 4000 Hz. Cortical thresholds were within 10 dB of behavioural thresholds for all four frequencies. Conclusions: Findings are encouraging for the feasibility of CATE as an alternative diagnostic test to pure-tone audiometry for adults living with dementia in aged care.
VP20-07 Design of a Novel Carbon Nanotube Based Coreless Axial Flux Motor with Heat Pipes

Publisher: name: IEEE
Year: 2025

This article presents the advancements and challenges in carbon nanotube (CNT) based axial flux motor topologies, focusing on coreless configurations. Despite the manufacturing ease of coreless axial motors, their limitations in high-power applications persist. To overcome this drawback, a novel customized carbon nanotube composite-based coreless motor configuration is proposed as shown in Fig. 1. This design aims to integrate the benefits of recently existing coreless configurations while addressing their drawbacks. Existing research indicates that heat pipes are becoming more popular for the thermal management of power-dense electric motors. However, the interaction of heat pipes with ohmic losses poses significant challenges, especially in coreless motors. Further, this article investigates the impact of heat pipe losses on the thermal management of CNT-based coreless motors. It highlights the necessity of addressing the interaction between heat pipes and electromagnetic fields. To mitigate these issues, a flux blanking method is presented to minimize ohmic losses associated with heat pipes. The effectiveness of this method is made evident by initial assessments, and further optimization is also discussed. Here, the flux blanking method has the potential to enhance thermal management in coreless motors, thereby facilitating the development of more efficient high-power applications.

description: Chiral coupling at the single-quantum level promises to be a remarkable potential for quantum information processing. Here we propose to achieve a chiral interaction between a magnon mode in a ferromagnetic sphere and a superconducting qubit mediated by a one-dimensional coupled-cavity array. When the qubit is coupled to two lattice sites of the array and each one is encoded with a tunable phase, we can acquire a directional qubit-magnon interaction via the quantum interference effect. This work opens up a new route to construct chiral devices, which are expected to become a building block in quantum magnonic networks.
Intersection Information based on Common Randomness

description: The introduction of the partial information decomposition generated a flurry of proposals for defining an intersection information that quantifies how much of "the same information" two or more random variables specify about a target random variable. As of yet, none is wholly satisfactory. A palatable measure of intersection information would provide a principled way to quantify slippery concepts, such as synergy. Here, we introduce an intersection information measure based on the Gács-Körner common random variable that is the first to satisfy the coveted target monotonicity property. Our measure is imperfect, too, and we suggest directions for improvement.

description: Il lavoro propone una sistematica valutazione economica di due importanti e recenti interventi di politica economica (i cosiddetti “bonus facciate” e “superbonus 110%”) con i quali sono state introdotte generose agevolazioni fiscali per ristrutturare e riqualificare il patrimonio edilizio privato italiano. I risultati della nostra analisi considerano le due misure meritevoli negli obiettivi, ma criticabili nella progettazione e nelle modalità di attuazione per gli effetti negativi in termini di spesa, efficienza ed equità. Il lavoro si conclude discutendo alcuni suggerimenti correttivi delle due misure adottate.

description: Given a property of Boolean functions, what is the minimum number of queries required to determine with high probability if an input function satisfies this property or is "far" from satisfying it? This is a fundamental question in Property Testing, where traditionally the testing algorithm is allowed to pick its queries among the entire set of inputs. Balcan, Blais, Blum and Yang have recently suggested to restrict the tester to take its queries from a smaller random subset of polynomial size of the inputs. This model is called active testing, and in the extreme case when the size of the set we can query from is exactly the number of queries performed it is known as passive testing. We prove that passive or active testing of k-linear functions (that is, sums of k variables among n over Z_2) requires Theta(k*log n) queries, assuming k is not too large. This extends the case k=1, (that is, dictator functions), analyzed by Balcan et. al. We also consider other classes of functions including low degree polynomials, juntas, and partially symmetric functions. Our methods combine algebraic, combinatorial, and probabilistic techniques, including the Talagrand concentration inequality and the Erdos--Rado theorem on Delta-systems.
