Material examined. Neotype female (no. 65892) from Cobell’s Canyon, Claremont, California, January 1938, determined by Hilton as Acerentulus californicus (Bonet & Tuxen 1960).
Remarks. Bonet & Tuxen (1960) synonymized this species with Acerentomon occidentalis Ewing, 1940 and redescribed it as Acerentulus californicus Hilton, 1929. Tuxen (1964) confirmed this synonymization and added some additional figures and a chaetotaxic formula.

description: We report a temperature dependent x-ray diffraction study of the electronic ordering instabilities in the kagome material CsV$_3$Sb$_5$. Our measurements between 10 K and 120 K reveal an unexpected reorganization of the three-dimensional electronic order in the bulk of CsV$_3$Sb$_5$: At 10 K, a 2x2x2 superstructure modulation due to electronic order is observed, which upon warming changes to a 2x2x4 superstructure at 60 K. The electronic order-order transition discovered here involves a change in the stacking of electronically ordered V$_3$Sb$_5$-layers and agrees perfectly with anomalies previously observed in magneto-transport measurements. This implies that the temperature dependent three-dimensional electronic order plays a decisive role for transport properties, which are related to the Berry-curvature of the V-bands. Our data also show that the bulk electronic order in CsV$_3$Sb$_5$ breaks the 6-fold rotational symmetry of the underlying $P6/mmm$ lattice structure.

description: Inflammatory bowel disease (IBD) requires complex clinical management. Despite substantial advancements in endoscopy and in pharmacotherapies for patients with IBD, it remains unclear how these developments have influenced IBD incidence and clinical care. We aim to describe changes in diagnostic and therapeutic practices in IBD management. All individuals diagnosed with IBD between 1987 and 2016 were identified from nationwide registries in Norway and Sweden. We performed detailed chart abstractions for a random sample of the cohort. We describe patient characteristics, disease extent, endoscopic practices, pathology diagnostics, pharmacological therapy and surgical management, stratifying by Crohn’s disease (CD) and ulcerative colitis [UC], comparing patients diagnosed before (pre-biologic period, 1987–1999), and after the introduction of biologic drugs (biologic period, 2000–2016). Chart abstraction was completed for 791 individuals (UC: 58.8%, Crohn’s disease: 40.2%, unclassified IBD: 1.0%). Comparing the biologic period to the pre-biologic period, we observed an increase in endoscopies after diagnosis, more frequent colonoscopies, and a decrease in colon resection rates. Among those diagnosed in 2007 or later compared with those diagnosed between 2000 and 2006, there was a higher treatment initiation rate of azathioprine, infliximab and adalimumab within 1 year after diagnosis. Our findings suggest a shift towards more frequent endoscopy, increased use of immunosuppressants and biologics, and decreased colon resection rates in recent periods.

description: We undertake the first comprehensive and quantitative real-space analysis of the cosmological information content in the environments of the cosmic web (voids, filaments, walls, and nodes) up to non-linear scales, $k = 0.5$ $h$/Mpc. Relying on the large set of $N$-body simulations from the Quijote suite, the environments are defined through the eigenvalues of the tidal tensor and the Fisher formalism is used to assess the constraining power of the power spectra derived in each of the four environments and their combination. Our results show that there is more information available in the environment-dependent power spectra, both individually and when combined all together, than in the matter power spectrum. By breaking some key degeneracies between parameters of the cosmological model such as $M_ν$--$σ_\mathrm{8}$ or $Ω_\mathrm{m}$--$σ_8$, the power spectra computed in identified environments improve the constraints on cosmological parameters by factors $\sim 15$ for the summed neutrino mass $M_ν$ and $\sim 8$ for the matter density $Ω_\mathrm{m}$ over those derived from the matter power spectrum. We show that these tighter constraints are obtained for a wide range of the maximum scale, from $k_\mathrm{max} = 0.1$ $h$/Mpc to highly non-linear regimes with $k_\mathrm{max} = 0.5$ $h$/Mpc. We also report an eight times higher value of the signal-to-noise ratio for the combination of spectra compared to the matter one. Importantly, we show that all the presented results are robust to variations of the parameters defining the environments hence suggesting a robustness to the definition we chose to define them.

description: In this work, we construct time-dependent potentials for the Schrödinger equation via supersymmetric quantum mechanics. The generated potentials have a quantum state with the property that after a particular threshold time $t_F$, when the potential does no longer change, the evolving state becomes a bound state in the continuum, its probability distribution freezes. After the factorization of a geometric phase, the state satisfies a stationary Schrödinger equation with time-independent potential. The procedure can be extended to support more than one bound state in the continuum. Closed expressions for the potential, the bound states in the continuum, and scattering states are given for the examples starting from the free particle.

description: We present a systematic study of the time and band-resolved scintillation in xenon-based time projection chambers (TPCs), performed simultaneously for the primary (S1) and secondary (S2) components in a small, purity-controlled, setup. We explore a range of conditions of general academic interest, focusing on those of relevance to contemporary TPCs: pressure range ([1- 10] bar), pressure-reduced electric fields ([0-100] V/cm/bar in the drift region (S1) and up to the proportional scintillation regime in the multiplication region (S2)), wavelength-band ([145-250], [250-400], [400-600] nm), and primary excitation ($α$, $β$-particles). Attention is paid to the possibility of non-conventional scintillation mechanisms such as the 3rd continuum emission, recombination light from $β$-electrons at high pressure (for S1), emission from high-lying excited states and neutral bremsstrahlung (for S2). Time constants and, specially, scintillation yields have been obtained as a function of electric field and pressure, the latter aided by Geant4 simulations.

description: We demonstrate a non-stereoscopic, video-based particle tracking system with optical tweezers to study fluid flow in 3D in the vicinity of glass nanopores. In particular, we used the Quadrant Interpolation algorithm to extend our video-based particle tracking to displacements out of the trapping plane of the tweezers. This permitted the study of flow from nanopores oriented at an angle to the trapping plane, enabling the mounting of nanopores on a micromanipulator with which it was then possible to automate the mapping procedure. Mapping of voltage driven flow in 3D volumes outside nanopores revealed polarity dependent flow fields. This is in agreement with the model of voltage driven flow in conical nanopores depending on the interaction of distinct flows within the nanopore and along the outer walls.

description: We present a design for an array of kinetic inductance detectors (KIDs) integrated with phased array antennas for imaging at 150 GHz under high background conditions. The microstrip geometry KID detectors are projected to achieve photon noise limited sensitivity with larger than 100 pW absorbed optical power. Both the microstrip KIDs and the antenna feed network make use of a low-loss amorphous silicon dielectric. A new aspect of the antenna implementation is the use of a NbTiN microstrip feed network to facilitate impedance matching to the 50 Ohm antenna. The array has 256 pixels on a 6-inch wafer and each pixel has two polarizations with two Al KIDs. The KIDs are designed with a half wavelength microstrip transmission line with parallel plate capacitors at the two ends. The resonance frequency range is 400 to 800 MHz. The readout feedline is also implemented in microstrip and has an impedance transformer from 50 Ohm to 9 Ohm at its input and output.

description: We explore the connections between dissipative quantum phase transitions and non-Hermitian random matrix theory. For this, we work in the framework of the dissipative Dicke model which is archetypal of symmetry-breaking phase transitions in open quantum systems. We establish that the Liouvillian describing the quantum dynamics exhibits distinct spectral features of integrable and chaotic character on the two sides of the critical point. We follow the distribution of the spacings of the complex Liouvillian eigenvalues across the critical point. In the normal and superradiant phases, the distributions are $2D$ Poisson and that of the Ginibre Unitary random matrix ensemble, respectively. Our results are corroborated by computing a recently introduced complex-plane generalization of the consecutive level-spacing ratio distribution. Our approach can be readily adapted for classifying the nature of quantum dynamics across dissipative critical points in other open quantum systems.

description: The self-lensing of a massive black hole binary (MBHB), which occurs when the two BHs are aligned close to the line of sight, is expected to produce periodic, short-duration flares. Here we study the shapes of self-lensing flares (SLFs) via general-relativistic ray tracing in a superimposed binary BH metric, in which the emission is generated by geometrically thin accretion flows around each component. The suite of models covers eccentric binary orbits, black hole spins, unequal mass binaries, and different emission model geometries. We explore the above parameter space, and report how the light curves change as a function of, e.g., binary separation, inclination, and eccentricity. We also compare our light curves to those in the microlensing approximation, and show how strong deflections, as well as time-delay effects, change the size and shape of the SLF. If gravitational waves (GWs) from the inspiraling MBHB are observed by LISA, SLFs can help securely identify the source and localizing it on the sky, and to constrain the graviton mass by comparing the phasing of the SLFs and the GWs. Additionally, when these systems are viewed edge-on the SLF shows a distinct dip that can be directly correlated with the BH shadow size. This opens a new way to measure BH shadow sizes in systems that are unresolvable by current VLBI facilities.

description: Supermassive black hole (BH) binaries are thought to produce self-lensing flares (SLF) when the two BHs are aligned with the line-of-sight. If the binary orbit is observed nearly edge-on, we find a distinct feature in the light curve imprinted by the BH shadow from the lensed BH. We study this feature by ray-tracing in a binary model and predict that 1\% of the current binary candidates could show this feature. Our BH tomography method proposed here could make it possible to extract BH shadows that are spatially unresolvable by high-resolution VLBI.

description: The stationary state of the spin-Hall bar is studied in the framework of a variational approach that includes non-equilibrium screening effects. The minimization of the power dissipated in the system is performed with taking into account the spin-flip relaxation and the global constrains due to the electric generator and global charge conservation. The calculation is performed in both approximations of negligible spin-flip scattering and strong spin-flip scattering. In both cases, the expressions of the spin-accumulation and the longitudinal and transverse pure spin-currents are derived analytically. Due to the small value of the Debye-Fermi screening length, the spin-accumulation is shown to be linear in $y$ (across the device), linear in the electric field imposed by the generator, and inversely proportional to the temperature for non-degenerate conductors.

description: Antiferromagnetic (AFM) spintronics has emerged as a subfield of spintronics driven by the advantages of antiferromagnets producing no stray fields and exhibiting ultrafast magnetization dynamics. The efficient method to detect an AFM order parameter, known as the Néel vector, by electric means is critical to realize concepts of AFM spintronics. Here, we demonstrate that non-collinear AFM metals, such as Mn3Sn, exhibit a momentum dependent spin polarization which can be exploited in AFM tunnel junctions to detect the Néel vector. Using first-principles calculations based on density functional theory, we predict a tunneling magnetoresistance (TMR) effect as high as 300% in AFM tunnel junctions with Mn3Sn electrodes, where the junction resistance depends on the relative orientation of their Néel vectors and exhibits four non-volatile resistance states. We argue that the spin-split band structure and the related TMR effect can also be realized in other non-collinear AFM metals like Mn3Ge, Mn3Ga, Mn3Pt, and Mn3GaN. Our work provides a robust method for detecting the Néel vector in non-collinear antiferromagnets via the TMR effect, which may be useful for their application in AFM spintronic devices.

description: Attractor neural networks (ANNs) are one of the leading theoretical frameworks for the formation and retrieval of memories in networks of biological neurons. In this framework, a pattern imposed by external inputs to the network is said to be learned when this pattern becomes a fixed point attractor of the network dynamics. The storage capacity is the maximum number of patterns that can be learned by the network. In this paper, we study the storage capacity of fully-connected and sparsely-connected networks with a binarized Hebbian rule, for arbitrary coding levels. Our results show that a network with discrete synapses has a similar storage capacity as the model with continuous synapses, and that this capacity tends asymptotically towards the optimal capacity, in the space of all possible binary connectivity matrices, in the sparse coding limit. We also derive finite coding level corrections for the asymptotic solution in the sparse coding limit. The result indicates the capacity of network with Hebbian learning rules converges to the optimal capacity extremely slowly when the coding level becomes small. Our results also show that in networks with sparse binary connectivity matrices, the information capacity per synapse is larger than in the fully connected case, and thus such networks store information more efficiently.

description: We study the coherent control of spin tunneling for a spin-orbit (SO) coupled boson held in a driven triple well. Under high-frequency approximation, we analytically obtain the quasienergies of the SO-coupled bosonic triple-well system and fine energy band structure is displayed. By adjusting the driving parameters, we reveal that the directed selective spin-flipping or spin-conserving tunneling of a SO-coupled boson occurs along different pathways and in different directions. The analytical results are numerically confirmed and perfect agreements are found. Further, a scheme of quantum spin switch with or without spin-flipping is presented. These results may be useful for quantum information processing and the design of spintronic devices.

description: Cerium substituted yttrium iron garnet (Ce:YIG) epitaxial thin films are prepared on gadolinium gallium garnet (GGG) substrate with pulsed laser deposition (PLD). It is observed that the films grown on GGG(111) substrate exhibit perpendicular magnetic anisotropy (PMA) as compared to films grown on GGG(100) substrate. The developed PMA is confirmed from magneto-optical Kerr effect, bulk magnetization and ferromagnetic resonance measurements. Further, the magnetic bubble domains are observed in the films exhibiting PMA. The observations are explained in terms of the growth direction of Ce:YIG films and the interplay of various magnetic anisotropy terms. The observed PMA is found to be tunable with thickness of the film and a remarkable temperature stability of the PMA is observed in all the studied films of Ce:YIG deposited on GGG(111) substrate.

description: Millilensing of Gamma-Ray Bursts (GRBs) is expected to manifest as multiple emission episodes in a single triggered GRB with similar light-curve patterns and similar spectrum properties. Identifying such lensed GRBs could help improve constraints on the abundance of compact dark matter. Here we present a systemic search for millilensing among 3000 GRBs observed by the \textit{Fermi} GBM up to 2021 April. Eventually we find 4 interesting candidates by performing auto-correlation test, hardness test, and time-integrated/resolved spectrum test to the whole sample. GRB 081126A and GRB 090717A are ranked as the first class candidate based on their excellent performance both in temporal and spectrum analysis. GRB 081122A and GRB 110517B are ranked as the second class candidates (suspected candidates), mainly because their two emission episodes show clear deviations in part of the time-resolved spectrum or in the time-integrated spectrum. Considering a point mass model for the gravitational lens, our results suggest that the density parameter of lens objects with mass $M_{\rm L}\sim10^{6} M_{\odot}$ is larger than $1.5\times10^{-3}$.

description: We study how the herd immunity threshold and the expected epidemic size depend on homophily with respect to vaccine adoption. We find that the presence of homophily considerably increases the critical vaccine coverage needed for herd immunity and that strong homophily can push the threshold entirely out of reach. The epidemic size monotonically increases as a function of homophily strength for a perfect vaccine, while it is maximized at a nontrivial level of homophily when the vaccine efficacy is limited. Our results highlight the importance of vaccination homophily in epidemic modeling.

description: We present results from ramp compression experiments on high-purity Zr that show the $α\rightarrow ω$, $ω\rightarrow β$, as well as reverse $β\rightarrow ω$ phase transitions. Simulations with a multi-phase equation of state and phenomenological kinetic model match the experimental wave profiles well. While the dynamic $α\rightarrow ω$ transition occurs $\sim 9$ GPa above the equilibrium phase boundary, the $ω\rightarrow β$ transition occurs within 0.9~GPa of equilibrium. We estimate that the dynamic compression path intersects the equilibrium $ω- β$ line at $P= 29.2$ GPa, and $T = 490$ K. The thermodynamic path in the interior of the sample lies $\sim 100$ K above the isentrope at the point of the $ω\rightarrow β$ transition. Approximately half of this dissipative temperature rise is due to plastic work, and half is due to the non-equilibrium $α\rightarrow ω$ transition. The inferred rate of the $α\rightarrow ω$ transition is several orders of magnitude higher than that measured in dynamic diamond anvil cell (DDAC) experiments in an overlapping pressure range. We discuss a model for the influence of shear stress on the nucleation rate. The small fractional volume change $ΔV/V \approx 0.1$ at the $α\rightarrow ω$ transition amplifies the effect of shear stress, and we estimate that for this case shear stress is equivalent to a pressure increase in the range of several GPa. Correcting our transition rate to a hydrostatic rate brings it approximately into line with the DDAC results, suggesting that shear stress plays a significant role in the transformation rate.

description: In this paper, we calculate the vector, axial-vector and tensor form factors of $P\to T$ transition within the standard light-front~(SLF) and covariant light-front~(CLF) quark models~(QMs). The self-consistency and Lorentz covariance of CLF QM with two types of correspondence schemes are investigated. The zero-mode effects and the spurious $ω$-dependent contributions to the form factors of $P\to T$ transition are analyzed. Employing a self-consistent CLF QM, we present our numerical predictions for the vector, axial-vector and tensor form factors of $c\to (q,s)$~($q=u,d$) induced $D \to (a_2,K^*_2)$, $D_s \to (K^*_2,f'_{2})$, $η_c(1S) \to (D^*_2,D^*_{s2})$, $ B_c \to (B^*_2,B^*_{s2})$ transitions and $b\to (q,s,c)$ induced $B \to (a_2,K^*_2,D^*_2)$, $B_s \to (K^*_2,f'_2,D^*_{s2})$, $B_c \to (D^*_2,D^*_{s2},χ_{c2}(1P))$, $η_b(1S) \to (B^*_2,B^*_{s2})$ transitions. Finally, in order to test the obtained form factors, the semileptonic $B\to \bar{D}_2^*(2460)\ell^+ν_\ell$~($\ell=e,μ$) and $\bar{D}_2^*(2460)τ^+ν_τ$ decays are studied. It is expected that our results for the form factors of $P\to T$ transition can be applied further to the relevant phenomenological studies of meson decays.

description: Jew university students’ experience – Italians and, above all, foreign students – and the impact of Italian racist legislation on their studies and destinies are still unknown. Lotte Dann Treves’s biography, considered here as an interesting case-study of this historic phenomenology, is focused on the diverse contexts of Fascist Italy, Italian University and particularly Turin. After a brief period of openness to international scientific mobility, under minister Bottai’s guidance, Italian University chose discrimination and expulsion of precious intellectual resources, such as precisely Lotte Dann and her famous teacher, Giuseppe Levi. In the Europe devastated by World War II, the contingency took Lotte Dann, became Mrs. Treves, back to Italy and its bumpy path of democratic reconstruction.

description: From Augsburg to Munich, from Turin to London, and again to Rome, Paris, United States of America and Israel, this personal diary shows the life and the scientific career of Lotte Dann Treves.
After Hitler’s advent to power she sought refuge in Italy, arriving in Turin in September 1933, so as to complete her studies in Medicine. She became a pupil of Professor Giuseppe Levi, in the prestigious Institute of Anatomy at the Turin University where the Nobel prizes Rita Levi Montalcini, Salvator Luria and Renato Dulbecco began their research activity. Graduated in July
1938, she was expelled from Italy after the racial laws and went to England, where she worked as a researcher, first at Strangeways Research Laboratory, Cambridge, and later at Mount Vernon Hospital, London. In Cambridge she met and later married the antifascist Paolo Treves, journalist and writer. Together they returned to Italy and settled in Rome (1945). Lotte Dann Treves worked as a translator and collaborator in several national and international conferences until 1995, when she retired.

DC and optical signatures of the topological reconstruction of the Fermi surface for electrons with parabolic band dispersion

description: We study the main intra-band and inter-band transport properties at zero temperature of free electron-like system undergoing a topological reconstruction of the Fermi surface for the two-dimensional and three-dimensional case. The calculated intra-band properties include the single-particle density of states, the total and the effective concentrations of electrons and the thermopower. As for the inter-band case, the real part of the conductivity has been calculated within the vanishing inter-band relaxation approximation as a function of the incident photon energy. Within this approach, it is shown that the optical conductivity has a nonvanishing component parallel to the reconstruction wave vector and the shape which depends on the value of the Fermi energy. Each dimensionality has its particular features in the transport quantities presented in the paper, which are discussed and compared with those in the free electron scenario. Finally, we identify the signature of the topological reconstruction of the Fermi surface in the intra-band and inter-band transport functions.
Qualche nota sui Carteggi ‘R. Michels e i sindacalisti’

description: The Robert Michels’ Archive at the Fondazione Einaudi in Turin keeps the correspondences between the German sociologist and several Italian Revolutionary syndicalists, including Arturo Labriola and Enrico Leone. Furthermore, it contains the mails that Michels received from Georges Sorel and Hubert Lagardelle. Compared to other historical sources (autobiography, diary, etc.), this consistent set of documents provides not only important information about the Michels’ political placement in the socialist movement, but permits also understanding his relevance in the European cultural context, reconstructing his network ofpersonal relationships. These unpublished documents cross the bounds of the studies about Michels, representing an important source for the political and cultural European history.

description: Lutefisk is a traditional Norwegian Christmas dish, made of dry cod soaked in a lye solution before re-hydrated. We report measurements of the tissue softness of cooked Lutefisk. Surprisingly, we find that the elastic modulus does not seem to depend heavily on cooking time, cooking temperature and the amount of salt, but depends instead mainly on the size of the fish fillets and the period of fishing. Although the salting and cooking of the Lutefisk affects strongly the visual aspect of the fish fillets, these changes are not measurable with a rheometer.

description: We study the space of supersymmetric AdS$_5$ solutions of type IIB supergravity corresponding to the conformal manifold of the dual $\mathcal{N}=1$ conformal field theory. We show that the background geometry naturally encodes a generalised holomorphic structure, dual to the superpotential of the field theory, with the existence of the full solution following from a continuity argument. In particular, this provides a solution to the long-standing problem of finding the gravity dual of the generic $\mathcal{N}=1$ deformations of $\mathcal{N}=4$ conformal field theory. Using this formalism, we derive a new result for the Hilbert series of the deformed field theories.

L’Autonomia universitaria fra passato e presente
Creators: name: Rosboch, Michele
Publisher: name: Rivista di Storia dell'Università di Torino
Year: 2013

description: The article examines the evolution of institutional structures in Italian Universities since XIX century. After the reforms realized by Alfieri and Boncompagni in the "Regno di Sardegna", we will follow the development after the Casati law and during the period of Italian unification. Indeed, during the XIX century, levels of autonomy of academies are very low and Universities lacked any legal personality.
This personality will be recognized only after the Gentile reform (1923), whilst autonomy will be consacrated in the Italian Republican Constitution (art. 33). Next developments in XX century, that found their apex in Ruperti reforms (1989-1991), let boundaries of autonomy increasing more and more, as the number of universities' sites and their activities.
Eventually, we will examine the consequences of the recent law 240/2010 over the extension of university autonomy, which has to be reshaped according to the actual lack of financial resources. Autonomy, as a relative and flexible concept, remains anyway a unique character of University, a guarantee and a defence for the liberty of research and teaching.

L’articolo esamina l’evoluzione degli assetti istituzionali delle Università italiane a partire dal secolo XIX. Dopo le riforme dei ministri Alfieri e Boncompagni nel Regno di Sardegna se ne segue lo sviluppo dopo la legge Casati ed il periodo dell’Unità. Nel corso del secolo XIX, in realtà, i livelli di autonomia degli Atenei sono molto ridotti e le Università sono mancanti anche della personalità giuridica.

Questa viene riconosciuta alle Università solo con la riforma Gentile (1923), mentre l’autonomia trova la sua piena consacrazione con la Costituzione repubblicana (art. 33). Le vicende successive del XX secolo, culminate con le riforme del ministro Ruberti (1989-1991), vedono l’accrescersi degli ambiti di autonomia, insieme al proliferare delle sedi universitarie e delle attività formative proposte.
Da ultimo, vengono esaminate le ricadute della recente legge 240/2010 sull’estensione dell’autonomia universitaria, che subisce nell’attuale contesto di carenza di risorse un deciso ridimensionamento. L’autonomia, quale concetto relativo e flessibile, resta – peraltro – contrassegno insostituibile dell’Università, a garanzia e presidio della libertà di ricerca e di insegnamento.

Coherent and incoherent superposition of transition matrix elements of the squeezing operator
Creators: name: Varro, Sandor
Publisher: name: arXiv
Year: 2021
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: We discuss the general matrix elements of the squeezing operator between number eigenstates of a harmonic oscillator (which may also represent a quantized mode of the electromagnetic radiation). These matrix elements have first been used by Popov and Perelomov (1969) long ago, in their thorough analysis of the parametric excitation of harmonic oscillators. They expressed the matrix elements in terms of transcendental functions, the associated Legendre functions. In the present paper we will show that these matrix elements can also be expressed by the classical Gegenbauer polynomials. This new expression makes it possible to determine coherent and incoherent superpositions of these matrix elements in closed analytic forms. As an application, we describe multiphoton transitions in the system "charged particle + electromagnetic radiation", induced by a (strong) coherent field or by a black-body radiation component (with a Planck-Bose photon number distribution). The exact results are compared with the semi-classical ones. We will show that in case of interaction with a thermal field, the semi-classical result (with a Gaussian stochastic field amplitude) yields an acceptable approximation only in the Rayleigh-Jeans limit, however, in the Wien limit it completely fails.

Una disputa storico-filosofica nella Torino del ‘500: Agostino Bucci interprete di Parmenide
Creators: name: Mammola, Simone
Publisher: name: Rivista di Storia dell'Università di Torino
Year: 2014

description: What was the level of philosophical discussion in the sixteenth-century Turin? The controversy conducted by Agostino Bucci in 1572 against the Neo-Platonic interpretation of Parmenides’ ontology in theological terms, in addition to being a little lesson in historical method, throws light (by reflex) on the presence in those years at the University of Turin of some important followers of a particular variant of Aristotelianism inspired by Simplicio and reprised in Padua by the teaching of Marco Antonio Genua. For Bucci the Being of which Parmenides speaks is not God, but it is a improper term to indicate the formal principle then clearly defined by Aristotle: but beyond this single issue, his very intent is to discredit the easy concordism underlying the Simplicius’ interpretation of Aristotle and common in Renaissance Neo-Platonism. All this suggests that Turin also participated in debates typical of the sixteenth-century Italian philosophy, though the history of his contribution is still largely to be written.

description: The spin Hall conductivity (SHC) and anomalous Hall conductivity (AHC) in more than 120 full Heusler compounds are calculated using density functional theory in a high-throughtput way. The electronic structures are mapped to the Wannier basis and the linear response theory is used to get the conductivity. Our results show that the mechanism under the SHC or AHC cannot be simply related to the valence electron numbers or atomic weights, is related to the very details of the electronic structure, which can only be obtained by calculations. A high throughput calculation is efficient to screen out the desired materials. According to our present results, Cu2CoSn, as well as Co2MnAl and Co2MnGa are candidates in spintronic materials regarding to their high SHC and AHC values, which can benefit the spin-torque-driven nanodevices.
