description: We present and analyze Raman spectra of the Mott insulator Ca$_2$RuO$_4$, whose quasi-two-dimensional antiferromagnetic order has been described as a condensate of low-lying spin-orbit excitons with angular momentum $J_{eff}=1$. In the $A_g$ polarization geometry, the amplitude (Higgs) mode of the spin-orbit condensate is directly probed in the scalar channel, thus avoiding infrared-singular magnon contributions. In the $B_{1g}$ geometry, we observe a single-magnon peak as well as two-magnon and two-Higgs excitations. Model calculations using exact diagonalization quantitatively agree with the observations. Together with recent neutron scattering data, our study provides strong evidence for excitonic magnetism in Ca$_2$RuO$_4$ and points out new perspectives for research on the Higgs mode in two dimensions.

description: In strong magnetic fields, massless electrons in graphene populate relativistic Landau levels with the square-root dependence of each level energy on its number and magnetic field. Interaction-induced deviations from this single-particle picture were observed in recent experiments on cyclotron resonance and magneto-Raman scattering. Previous attempts to calculate such deviations theoretically using the unscreened Coulomb interaction resulted in overestimated many-body effects. This work presents many-body calculations of cyclotron and magneto-Raman transitions in single-layer graphene in the presence of Coulomb interaction, which is statically screened in the random-phase approximation. We take into account self-energy and excitonic effects as well as Landau level mixing, and achieve good agreement of our results with the experimental data for graphene on different substrates. Important role of a self-consistent treatment of the screening is found.

Kant, Husserl, McDowell: The Non-Conceptual in Experience
Creators: name: Van Mazijk, Corijn
Publisher: name: Diametros
Year: 2014

description: In this paper I compare McDowell′s conceptualism to Husserl′s later philosophy. I aim to argue against the picture provided by recent phenomenologists according to which both agree on the conceptual nature of experience. I start by discussing McDowell′s reading of Kant and some of the recent Kantian and phenomenological non-conceptualist criticisms thereof. By separating two kinds of conceptualism, I argue that these criticisms largely fail to trouble McDowell. I then move to Husserl’s later phenomenological analyses of types and of passive synthesis. Although Husserl appropriates McDowell’s idea of conceptually ‘saddled’ intuitions as a ‘secondary passivity’, I argue that he also provides a strong case for non-conceptual synthesis.

description: This paper reports the measurement of J/psi meson production in proton-proton (pp) and proton-lead (pPb) collisions at a center-of-mass energy per nucleon pair of 5.02 TeV by the CMS experiment at the LHC. The data samples used in the analysis correspond to integrated luminosities of 28 inverse picobarns and 35 inverse nanobarns for pp and pPb collisions, respectively. Prompt and nonprompt J/psi mesons, the latter produced from the decay of B mesons, are measured in their dimuon decay channels. Differential cross sections are measured in the transverse momentum range of 2 < pt < 30 GeV/c, and center-of-mass rapidity ranges of abs(y[CM]) < 2.4 (pp) and -2.87 < y[CM] < 1.93 (pPb). The nuclear modification factor, R[pPb], is measured as functions of both pt and y[CM]. Small modifications of the J/psi cross sections are observed in pPb relative to pp collisions. The ratio of J/psi production cross sections in p-going and Pb-going directions, R[FB], studied as functions of pt and y[CM], shows a significant decrease for increasing transverse energy deposited at large pseudorapidities. These results, which cover a wide kinematic range, provide new insight on the role of cold nuclear matter effects on prompt and nonprompt J/psi production.

The imperfect invariance problem modifies cortical signals during listening in noise

description: Imperfect invariances in speech pose a challenge to speech perception. When listening to speech in noise, finding regularities is hindered not only by noise but also the signal itself, as it varies due to coarticulation, underarticulation, and individual speaker characteristics. What is the minimal amount of invariance that is needed to perceive a coherent auditory object? To investigate the imperfect invariance problem in noise, we employed the stochastic figure-ground (SFG) task, which has been established as a suitable model for speech-in-noise listening. The SFG task uses random noise created from 50 ms long pure tones ("ground") and an embedded set of tones coherently fluctuating together over time ("figure"). We modified the number of tones available at different time points in the figure. We recorded the electroencephalogram (EEG) and analyzed event-related brain potentials (ERPs) while listeners tried to detect the figure segments.

Twenty-two healthy young adults listened to SFG stimuli of 3 s duration each. Half of the trials contained a figure, and half contained a random background only. Participants indicated whether there was a figure in each trial. All stimuli consisted of pure tones of 20 discrete frequencies, selected from a larger set. Figures contained a set of 10 potential repeating frequencies. We varied in three conditions how many of these frequencies were concurrently present in the stimulus: 10/10, 7/10, or 4/10 frequencies. While the overall number of repeating frequencies remained constant throughout the figure, the actual frequencies being present (permuted from the set of 10) changed at every 50 ms of the figure. This models the imperfect invariance problem: out of a set of possible components, only a subset is present in the stimulus at each time point, the subset varying throughout the whole stimulus.

We found that the number of repeating frequencies affects the object-related negativity (ORN) and P400 ERP responses to figure segments. Figures with 10/10 coherent frequencies elicited both ERP components with the largest amplitude, followed by figures at 7/10 coherent frequencies, and yet smaller amplitudes at 4/10 coherent frequencies. Further, we found no difference between ORN and P400 when comparing 4/10 coherent frequencies with the no-figure trials. These results suggest that a 40% invariance in frequency components is insufficient to detect an auditory object in noise (fluctuating energetic masking), but a 70% invariance is sufficient. We discuss these conclusions and their significance for speech-in-noise listening in the poster presentation.
Reflections in a Mirror

description: In this paper, I develop a solution to the puzzle of mirror perception: why do mirrors appear to reverse the image of an object along a left/right axis and not around other axes, such as the top/bottom axis? I set out the different forms the puzzle takes and argue that one form of it – arguably the key form – has not been satisfactorily solved. I offer a solution in three parts: setting out the conditions in which an apparent left/right reversal of mirror images is generated; explaining why these conditions are so often met; explaining why we are cognitively biased towards the perception of left/right reversal when these conditions are met.

Successive Rank-One Approximations for Nearly Orthogonally Decomposable Symmetric Tensors

description: Many idealized problems in signal processing, machine learning and statistics can be reduced to the problem of finding the symmetric canonical decomposition of an underlying symmetric and orthogonally decomposable (SOD) tensor. Drawing inspiration from the matrix case, the successive rank-one approximations (SROA) scheme has been proposed and shown to yield this tensor decomposition exactly, and a plethora of numerical methods have thus been developed for the tensor rank-one approximation problem. In practice, however, the inevitable errors (say) from estimation, computation, and modeling necessitate that the input tensor can only be assumed to be a nearly SOD tensor---i.e., a symmetric tensor slightly perturbed from the underlying SOD tensor. This article shows that even in the presence of perturbation, SROA can still robustly recover the symmetric canonical decomposition of the underlying tensor. It is shown that when the perturbation error is small enough, the approximation errors do not accumulate with the iteration number. Numerical results are presented to support the theoretical findings.
How the types of sound reflections influence speech intelligibility in rooms
Creators: name: Prodi, Nicola
Publisher: name: Zenodo
Year: 2024

description: Depending on the room boundaries, the sound reflections following the direct sound in a room can be either specular or at least partly diffusive, the latter also named scattered. While specular reflections are correlated by nature, scattered ones are usually uncorrelated. Still limited research has been directed to the understanding of how our auditory system incorporates the early sound energy from either type of reflection and the results are not entirely consistent. The amount of early sound energy is highly relevant in the context of speech intelligibility of a target source in rooms due to the time limit of the useful energy integration. In addition, part of the binaural information coded in the target impulse response can be used to estimate the binaural unmasking. For this scope the interaural phase difference between target and masker is used in equalization-cancellation (E-C) based models together with the masker correlation. In similar E-C modelling frameworks the correlation of the target signal is almost disregarded: this is realistic as far as a short source-receiver distance is considered or if the environment is very damped. Actually, in a real context, target correlation may vary, and is modulated either by the type of reflection, by reverberation, by distance or by a mixture of all the factors.  Unfortunately, the accurate control of target correlation alone while keeping other speech qualities untouched is not trivial. In recent years much effort was made to disentangle the role of target correlation from other known monaural and binaural factors influencing speech intelligibility. In one experiment based on simulations the whole impulse response consisted of either specular or scattered reflections while monaural and binaural indicators were kept fixed. The noise was localized and it was either energetic or informational. The obtained spatial release from masking (SRM) differed for the two types of reflections, specular and diffuse, and the former ensured better performance. The E-C modelling approach helped to isolate the contributions of better-ear and binaural unmasking. In another experiment based on real measures the target correlation was further investigated by comparing symmetric scattered early reflections (that, although diffuse, keep an high left-right correlation) against unsymmetric ones that provide very low left-right correlation. The interferer’s correlation was modulated too. Results helped in better understanding the role of target correlation and provide grounds for better acoustical design of rooms for speech.

Laser pulses with different envelope shapes are examined by means of a nonperturbative numerical technique. We analyze two different "flat" envelope shapes and two shapes without a plateau for their various parameters including the carrier-envelope phase. The resonant Rabi oscillations, momentum distribution of particles created, and total number of pairs are studied. It is demonstrated that all these characteristics are very sensitive to the pulse shape.

Monetary Spillover and Policy Responses: How Do Central Banks React to the Fed and Why?
Creators: name: Sun, Ziwen
Publisher: name: University of Chicago
Year: 2022
Subjects: subject: Monetary Spillover
subject: Central Bank Balance Sheet
subject: International Transmission

description: This paper studies how the Federal Reserve’s monetary stance affects the policy-making of other central banks, i.e., policy rates and balance sheet operations. I decompose monetary shocks into an interest rate shock and a risk premium shock using high-frequency monetary identification. I find the responses of policy rates are largely homogeneous across emerging and advanced economies. For balance sheet operations, however, a positive interest rate shock leads other central banks to shrink their asset holdings mostly by reducing claims on depository institutions and government agencies, while a positive risk premium shock has an immediate and positive effect on central banks’ total asset. The transmissions of both shocks are weak before 2008, and becomes important afterwards. Notably, emerging economies cope with international spillovers primarily with foreign reserve operations, and advanced economies with domestic monetary policies. Surprisingly, emerging economies employ unconventional instruments in response to a risk premium shock while advanced economies do not. A simple model of international financial intermediaries is introduced to provide a rationale for some important empirical findings.

description: The mechanism of the collapse of the superhydrophobic state is elucidated for submerged nanoscale textures forming a three-dimensional interconnected vapor domain. This key issue for the design of nanotextures poses significant simulation challenges as it is characterized by diverse time and length scales. State-of-the-art atomistic rare events simulations are applied for overcoming the long time scales connected with the large free energy barriers. In such interconnected surface cavities wetting starts with the formation of a liquid finger between two pillars. This break of symmetry induces a more gentle bend in the rest of the liquid-vapor interface, which triggers the wetting of the neighboring pillars. This collective mechanism, involving the wetting of several pillars at the same time, could not be captured by previous atomistic simulations using surface models comprising a small number of pillars (often just one). Atomistic results are interpreted in terms of a sharp-interface continuum model which suggests that line tension, condensation, and other nanoscale phenomena play a minor role in the simulated conditions.

description: Post-graduation employment outcomes remain a central focus for students, tertiary institutions, and governments. This interest has seen universities now aiming to provide students with a wide variety of authentic employability or career readiness opportunities to support each student’s work-ready preparedness, in a scalable and transferrable manner. This study explored the extent to which students perceive and value career readiness opportunities undertaken within their undergraduate degrees. Scaffolded opportunities and assessments were undertaken by students enrolled in professional and generic degrees within a Health Faculty. The activities and their assessment design aimed to support student career planning and readiness for future employment. This research affirmed the importance of embedding employability-focused curriculum throughout the degree, especially in first-year subjects within both professional and generic degrees. Whether the employability activity was a stand-alone assessment task, or intentionally designed to explicitly address employability and career readiness over the entire semester, students appreciated it. They recognised the value of these initiatives in enhancing their career readiness and facilitating their transition to employment. Multiple employability assessments scaffolded within subjects and throughout degrees can effectively cater to diverse student groups, providing opportunities to enhance their skills and confidence as they navigate the path to employment.
Frontier molecular orbitals of single molecules adsorbed on thin insulating films supported by a metal substrate: A simplified density functional theory approach

description: We present a simplified density functional theory (DFT) method to com- pute vertical electron and hole attachment energies to frontier orbitals of molecules absorbed on insulating films supported by a metal substrate. The adsorbate and the film is treated fully within DFT, whereas the metal is treated implicitly by a perfect conductor model. As illustrated for a pentacene molecule adsorbed on NaCl films sup- ported by a Cu substrate, we find that the computed energy gap between the highest and lowest occupied molecular orbitals - HOMO and LUMO -from the vertical attach- ment energies increases with the thickness of the insulating film, in agreement with experiments. This increase of the gap can be rationalized in a simple dielectric model with parameters determined from DFT calculations and is found to be dominated by the image interaction with the metal. However, this model overestimates the down- ward shift of the energy gap in the limit of an infinitely thick film. This work provides a new and efficient strategy to extend the use of density functional theory to the study of charging and discharging of large molecular absorbates on insulating films supported by a metal substrate.

description: We develop an explicit theory of Kummer varieties associated to Jacobians of hyperelliptic curves of genus 3, over any field $k$ of characteristic $\neq 2$. In particular, we provide explicit equations defining the Kummer variety $\mathcal K$ as a subvariety of $\mathbb P^7$, together with explicit polynomials giving the duplication map on $\mathcal K$. A careful study of the degenerations of this map then forms the basis for the development of an explicit theory of heights on such Jacobians when $k$ is a number field. We use this input to obtain a good bound on the difference between naive and canonical height, which is a necessary ingredient for the explicit determination of the Mordell-Weil group. We illustrate our results with two examples.

description: The localization of the repeating FRB 121102 to a low-metallicity dwarf galaxy at $z=0.193$, and its association with a quiescent radio source, suggests the possibility that FRBs originate from magnetars, formed by the unusual supernovae in such galaxies. We investigate this via a comparison of magnetar birth rates, the FRB volumetric rate, and host galaxy demographics. We calculate average volumetric rates of possible millisecond magnetar production channels such as superluminous supernovae (SLSNe), long and short gamma-ray bursts (GRBs), and general magnetar production via core-collapse supernovae. For each channel we also explore the expected host galaxy demographics using their known properties. We determine for the first time the number density of FRB emitters (the product of their volumetric birthrate and lifetime), $R_{\rm FRB}τ\approx 10^4$Gpc$^{-3}$, assuming that FRBs are predominantly emitted from repetitive sources similar to FRB 121102 and adopting a beaming factor of 0.1. By comparing rates we find that production via rare channels (SLSNe, GRBs) implies a typical FRB lifetime of $\approx$30-300 yr, in good agreement with other lines of argument. The total energy emitted over this time is consistent with the available energy stored in the magnetic field. On the other hand, any relation to magnetars produced via normal core-collapse supernovae leads to a very short lifetime of $\approx$0.5yr, in conflict with both theory and observation. We demonstrate that due to the diverse host galaxy distributions of the different progenitor channels, many possible sources of FRB birth can be ruled out with $\lesssim 10$ host galaxy identifications. Conversely, targeted searches of galaxies that have previously hosted decades-old SLSNe and GRBs may be a fruitful strategy for discovering new FRBs and related quiescent radio sources, and determining the nature of their progenitors.

We demonstrate that in the particular case of N=(1,1) SYM theory, which corresponds to the hypermultiplet in the adjoint representation, all one-loop divergencies vanish, so that N=(1,1) SYM theory is one-loop finite {\it off shell}.

L’analisi è condotta con particolare riferimento alla fattispecie delle molestie sul lavoro, come disciplinata dalla Convenzione OIL n. 190/2019 (ratificata in Italia con la legge n. 4/2021) e parimenti richiamata dalle norme sulla certificazione volontaria della parità di genere contenute nella legge n. 162/2021 e nelle Linee Guida Uni PdR 125:2022.
Dopo una disamina delle preliminari questioni definitorie del fenomeno, nel più ampio scenario dei rischi psicosociali valutabili ex art. 28 del d.lgs. n. 81/2008, il saggio si intrattiene sulla sua regolazione multilivello nel contesto transdisciplinare sopra delineato, dedicando particolare attenzione alle diverse implicazioni del complessivo quadro regolatorio sulle prospettive rimediali e sull’apparato di tutela.
Viene altresì analizzata, in chiave critico-evolutiva, la funzione che la valutazione del rischio molestie può svolgere nel percorso di adozione di protocolli prevenzionistici dei modelli di organizzazione e gestione e dei sistemi di gestione per la salute e la sicurezza sul lavoro, nonché nel procedimento che conduce alla certificazione della parità di genere in cui la puntuale valutazione di questo rischio, unitamente agli interventi formativi sulla “tolleranza zero” e alla creazione di un peculiare sistema di gestione della parità, rappresenta una condico sine qua non per il rilascio della certificazione.

description: The linear superposition principle in quantum mechanics is essential for several no-go theorems such as the no-cloning theorem, the no-deleting theorem and the no-superposing theorem. It remains an open problem of finding general forbidden principles to unify these results. In this paper, we investigate general quantum transformations forbidden or permitted by the superposition principle for various goals. First, we prove a no-encoding theorem that forbids linearly superposing of an unknown pure state and a fixed state in Hilbert space of finite dimension. Two general forms include the no-cloning theorem, the no-deleting theorem, and the no-superposing theorem as special cases. Second, we provide a unified scheme for presenting perfect and imperfect quantum tasks (cloning and deleting) in a one-shot manner. This scheme may yield to fruitful results that are completely characterized with the linear independence of the input pure states. The generalized upper bounds for the success probability will be proved. Third, we generalize a recent superposing of unknown states with fixed overlaps when multiple copies of the input states are available.

description: Approximately half of the world’s mangroves are concentrated in Asia, but they have been logged at an alarming rate. To compensate for this, mangrove plantations are being attempted at various sites but with many failures. In this study, we investigated the role of a small portable reef in protecting young mangrove plants from hydrodynamic disturbances caused by short-period waves. To investigate the effectiveness of such a small reef, an experiment using a large wave flume was conducted with two types of real-sized portable reefs (stone and block reefs). A numerical wave model was also constructed to analyze in detail the turbulence around the reef. Our previous study showed that short-period waves can cause resonant oscillations in young mangrove plants. To confirm whether this occurs even behind a reef system, a young mangrove model made of flexible olefin resin was tested with a small wave flume placed behind porous and non-porous reefs, and its oscillation was precisely measured using a high-speed camera. These experiments yielded several new findings. If appropriately designed, small porous reefs can minimize oscillations with adverse effects and provide a favorable environment for the initial growth of mangroves at restoration sites.

description: We introduce a new technique for determining x-ray fluorescence line energies and widths, and we present measurements made with this technique of 22 x-ray L lines from lanthanide-series elements. The technique uses arrays of transition-edge sensors, microcalorimeters with high energy-resolving power that simultaneously observe both calibrated x-ray standards and the x-ray emission lines under study. The uncertainty in absolute line energies is generally less than 0.4 eV in the energy range of 4.5 keV to 7.5 keV. Of the seventeen line energies of neodymium, samarium, and holmium, thirteen are found to be consistent with the available x-ray reference data measured after 1990; only two of the four lines for which reference data predate 1980, however, are consistent with our results. Five lines of terbium are measured with uncertainties that improve on those of existing data by factors of two or more. These results eliminate a significant discrepancy between measured and calculated x-ray line energies for the terbium Ll line (5.551 keV). The line widths are also measured, with uncertainties of 0.6 eV or less on the full-width at half-maximum in most cases. These measurements were made with an array of approximately one hundred superconducting x- ray microcalorimeters, each sensitive to an energy band from 1 keV to 8 keV. No energy-dispersive spectrometer has previously been used for absolute-energy estimation at this level of accuracy. Future spectrometers, with superior linearity and energy resolution, will allow us to improve on these results and expand the measurements to more elements and a wider range of line energies.

description: We studied the properties of a single impurity atom immersed in a dilute Bose condensate at low temperatures. In particular, we perturbatively obtained the momentum dependence of the impurity spectrum and damping. By means of the Brillouin-Wigner perturbation theory we also calculated the self-energy both for attractive and repulsive polaron in the long-wavelength limit. The stability problem of the impurity atom in a weakly-interacting Bose gas is also examined.

Connection between Fermi contours of zero-field electrons and $ν=\frac12$ composite fermions in two-dimensional systems

description: We investigate the relation between the Fermi sea (FS) of zero-field carriers in two-dimensional systems and the FS of the corresponding composite fermions which emerge in a high magnetic field at filling $ν= \frac{1}{2}$, as the kinetic energy dispersion is varied. We study cases both with and without rotational symmetry, and find that there is generally no straightforward relation between the geometric shapes and topologies of the two FSs. In particular, we show analytically that the composite Fermi liquid (CFL) is completely insensitive to a wide range of changes to the zero-field dispersion which preserve rotational symmetry, including ones that break the zero-field FS into multiple disconnected pieces. In the absence of rotational symmetry, we show that the notion of `valley pseudospin' in many-valley systems is generically not transferred to the CFL, in agreement with experimental observations. We also discuss how a rotationally symmetric band structure can induce a reordering of the Landau levels, opening interesting possibilities of observing higher-Landau-level physics in the high-field regime.

Cosmic microwave background limits on accreting primordial black holes

description: Interest in the idea that primordial black holes (PBHs) might comprise some or all of the dark matter has recently been rekindled following LIGO's first direct detection of a binary-black-hole merger. Here we revisit the effect of accreting PBHs on the cosmic microwave background (CMB) frequency spectrum and angular temperature/polarization power spectra. We compute the accretion rate and luminosity of PBHs, accounting for their suppression by Compton drag and Compton cooling by CMB photons. We estimate the gas temperature near the Schwarzschild radius, and hence the free-free luminosity, accounting for the cooling resulting from collisional ionization when the background gas is mostly neutral. We account approximately for the velocities of PBHs with respect to the background gas. We provide a simple analytic estimate of the efficiency of energy deposition in the plasma. We find that the spectral distortions generated by accreting PBHs are too small to be detected by FIRAS, as well as by future experiments now being considered. We analyze Planck CMB temperature and polarization data and find, under our most conservative hypotheses, and at the order-of-magnitude level, that they rule out PBHs with masses >~ 10^2 M_sun as the dominant component of dark matter.
description: Version accepted in PRD. Main changes: (i) new section on local radiative feedback. (ii) replaced the "strong feedback" limit by a "photoionization" limit. Massive PBHs have a higher luminosity and tighter constraints in the latter than in the former. The most conservative bounds (derived in the "collisional ionization" limit, equivalent to the "no feedback" case in v1) remain unchanged

A scalable approach for tree segmentation within small-footprint airborne LiDAR data

description: This paper presents a distributed approach that scales up to segment tree crowns within a LiDAR point cloud representing an arbitrarily large forested area. The approach uses a single-processor tree segmentation algorithm as a building block in order to process the data delivered in the shape of tiles in parallel. The distributed processing is performed in a master-slave manner, in which the master maintains the global map of the tiles and coordinates the slaves that segment tree crowns within and across the boundaries of the tiles. A minimal bias was introduced to the number of detected trees because of trees lying across the tile boundaries, which was quantified and adjusted for. Theoretical and experimental analyses of the runtime of the approach revealed a near linear speedup. The estimated number of trees categorized by crown class and the associated error margins as well as the height distribution of the detected trees aligned well with field estimations, verifying that the distributed approach works correctly. The approach enables providing information of individual tree locations and point cloud segments for a forest-level area in a timely manner, which can be used to create detailed remotely sensed forest inventories. Although the approach was presented for tree segmentation within LiDAR point clouds, the idea can also be generalized to scale up processing other big spatial datasets. Highlights: - A scalable distributed approach for tree segmentation was developed and theoretically analyzed. - ~2 million trees in a 7440 ha forest was segmented in 2.5 hours using 192 cores. - 2% false positive trees were identified as a result of the distributed run. - The approach can be used to scale up processing other big spatial data
