description: The spin-dependent electron transmission through a helical membrane with account of linear spin-orbit interaction has been investigated by numerically solving the Schrödinger equation in cylindrical coordinates . It is shown that the spin precession is affected by the magnitude of geometric parameters and chirality of the membrane. This effect is also explained analytically by using the perturbation theory in the weak coupling regime. In the strong coupling regime, the current spin polarization is evident when the number of the open modes in leads is larger than that of the open channels in the membrane. Moreover, we find that the chirality of the helical membrane can determine the orientation of current spin polarization. Therefore, one may get totally opposite spin currents from the helical membranes rolled against different directions.

description: We report on the first experimental observation of graphene optical emission induced by the intense THz pulse. P-doped CVD graphene with the initial Fermi energy of about 200 meV was used, optical photons was detected in the wavelength range of 340-600 nm. Emission started when THz field amplitude exceeded 100 kV/cm. For THz fields from 200 to 300 kV/cm the temperature of optical radiation was constant, while the number of emitted photons increased several dozen times. This fact clearly indicates multiplication of electron-hole pairs induced by an external field itself and not due to electron heating. The experimental data are in a good agreement with the theory of Landau-Zener interband transitions. It is shown theoretically that Landau-Zener transitions are possible even in the case of heavily doped graphene because the strong THz field removes quasiparticles from the region of interband transitions during several femtoseconds, which cancels the Pauli blocking effect.
Equilibration and hydrodynamics at strong and weak coupling

description: We give an updated overview of both weak and strong coupling methods to describe the approach to a plasma described by viscous hydrodynamics, a process now called hydrodynamisation. At weak coupling the very first moments after a heavy ion collision is described by the colour-glass condensate framework, but quickly thereafter the mean free path is long enough for kinetic theory to become applicable. Recent simulations indicate thermalization in a time $t\sim40(η/s)^{4/3}/T$ [1], with $T$ the temperature at that time and $η/s$ the shear viscosity divided by the entropy density. At (infinitely) strong coupling it is possible to mimic heavy ion collisions by using holography, which leads to a dual description of colliding gravitational shock waves. The plasma formed hydrodynamises within a time of $0.41/T$. A recent extension found corrections to this result for finite values of the coupling, when $η/s$ is bigger than the canonical value of $1/4π$, which leads to $t\sim(0.41+1.6(η/s-1/4π))/T$ [2]. Future improvements include the inclusion of the effects of the running coupling constant in QCD.

description: We study the matter effect caused by nonstandard neutrino interactions (NSI) in the next generation long-baseline neutrino experiments, DUNE, T2HK and T2HKK. If multiple NSI parameters are nonzero, the potential of these experiments to detect CP violation, determine the mass hierarchy and constrain NSI is severely impaired by degeneracies between the NSI parameters and by the generalized mass hierarchy degeneracy. In particular, a cancellation between leading order terms in the appearance channels when $ε_{eτ} = \cotθ_{23} ε_{eμ}$, strongly affects the sensitivities to these two NSI parameters at T2HK and T2HKK. We also study the dependence of the sensitivities on the true CP phase $δ$ and the true mass hierarchy, and find that overall DUNE has the best sensitivity to the magnitude of the NSI parameters, while T2HKK has the best sensitivity to CP violation whether or not there are NSI. Furthermore, for T2HKK a smaller off-axis angle for the Korean detector is better overall. We find that due to the structure of the leading order terms in the appearance channel probabilities, the NSI sensitivities in a given experiment are similar for both mass hierarchies, modulo the phase change $δ\to δ+ 180^\circ$.

description: We present 21 new radio-continuum detections at catalogued planetary nebula (PN) positions in the Large Magellanic Cloud (LMC) using all presently available data from the Australia Telescope Online Archive at 3, 6, 13 and 20 cm. Additionally, 11 previously detected LMC radio PNe are re-examined with $ 7 $ detections confirmed and reported here. An additional three PNe from our previous surveys are also studied. The last of the 11 previous detections is now classified as a compact \HII\ region which makes for a total sample of 31 radio PNe in the LMC. The radio-surface brightness to diameter ($Σ$-D) relation is parametrised as $Σ\propto {D^{ - β}}$. With the available 6~cm $Σ$-$D$ data we construct $Σ$-$D$ samples from 28 LMC PNe and 9 Small Magellanic Cloud (SMC) radio detected PNe. The results of our sampled PNe in the Magellanic Clouds (MCs) are comparable to previous measurements of the Galactic PNe. We obtain $β=2.9\pm0.4$ for the MC PNe compared to $β= 3.1\pm0.4$ for the Galaxy. For a better insight into sample completeness and evolutionary features we reconstruct the $Σ$-$D$ data probability density function (PDF). The PDF analysis implies that PNe are not likely to follow linear evolutionary paths. To estimate the significance of sensitivity selection effects we perform a Monte Carlo sensitivity simulation on the $Σ$-$D$ data. The results suggest that selection effects are significant for values larger than $β\sim 2.6$ and that a measured slope of $β=2.9$ should correspond to a sensitivity-free value of $\sim 3.4$.

description: Fermi arc surface states, a hallmark of topological Dirac semimetals, can host carriers that exhibit unusual dynamics distinct from that of their parent bulk. Here we find that Fermi arc carriers in intrinsic Dirac semimetals possess a strong and anisotropic light matter interaction. This is characterized by a large Fermi arc optical conductivity when light is polarized transverse to the Fermi arc; when light is polarized along the Fermi arc, Fermi arc optical conductivity is significantly muted. The large surface spectral weight is locked to the wide separation between Dirac nodes and persists as a large Drude weight of Fermi arc carriers when the system is doped. As a result, large and anisotropic Fermi arc conductivity provides a novel means of optically interrogating the topological surfaces states of Dirac semimetals.

description: Android malware has been on the rise in recent years due to the increasing popularity of Android and the proliferation of third party application markets. Emerging Android malware families are increasingly adopting sophisticated detection avoidance techniques and this calls for more effective approaches for Android malware detection. Hence, in this paper we present and evaluate an n-gram opcode features based approach that utilizes machine learning to identify and categorize Android malware. This approach enables automated feature discovery without relying on prior expert or domain knowledge for pre-determined features. Furthermore, by using a data segmentation technique for feature selection, our analysis is able to scale up to 10-gram opcodes. Our experiments on a dataset of 2520 samples showed an f-measure of 98% using the n-gram opcode based approach. We also provide empirical findings that illustrate factors that have probable impact on the overall n-gram opcodes performance trends.

description: Iron–tungsten/TiO2 nanotube photoelectrodes have been synthesised by the anodisation process followed by the chemical bath deposition technique in this work. X-ray diffraction analysis, field emission scanning electron microscopy, UV–Vis, energy-dispersive X-ray spectroscopy and photoelectrochemical (PEC) measurements have been used to characterise these photoelectrodes. The ratio of the iron–tungsten deposited on TiO2 nanotubes remarkably influences the PEC performance and the amount of hydrogen. The A1 photoelectrode showed the best PEC activity. The investigation of the recyclability of these new TiO2 nanotubes indicated good stability of their photocatalytic activity. A simple method for the synthesis of high-performance PEC photoelectrodes with good stability and reliability has been provided by this work.

description: Correction of Type Ia Supernova brightnesses for extinction by dust has proven to be a vexing problem. Here we study the dust foreground to the highly reddened SN 2012cu, which is projected onto a dust lane in the galaxy NGC 4772. The analysis is based on multi-epoch, spectrophotometric observations spanning 3,300 - 9,200 Å, obtained by the Nearby Supernova Factory. Phase-matched comparison of the spectroscopically twinned SN 2012cu and SN 2011fe across 10 epochs results in the best-fit color excess of (E(B-V), RMS) = (1.00, 0.03) and total-to-selective extinction ratio of (RV , RMS) = (2.95, 0.08) toward SN 2012cu within its host galaxy. We further identify several diffuse interstellar bands, and compare the 5780 Å band with the dust-to-band ratio for the Milky Way. Overall, we find the foreground dust-extinction properties for SN 2012cu to be consistent with those of the Milky Way. Furthermore we find no evidence for significant time variation in any of these extinction tracers. We also compare the dust extinction curve models of Cardelli et al. (1989), O'Donnell (1994), and Fitzpatrick (1999), and find the predictions of Fitzpatrick (1999) fit SN 2012cu the best. Finally, the distance to NGC4772, the host of SN 2012cu, at a redshift of z = 0.0035, often assigned to the Virgo Southern Extension, is determined to be 16.6$\pm$1.1 Mpc. We compare this result with distance measurements in the literature.

description: In recent years the interest in studying interactions of Rydberg atoms or ensembles thereof with optical and microwave frequency fields has steadily increased, both in the context of basic research and for potential applications in quantum information processing. We present measurements of the dispersive interaction between an ensemble of helium atoms in the 37s Rydberg state and a single resonator mode by extracting the amplitude and phase change of a weak microwave probe tone transmitted through the cavity. The results are in quantitative agreement with predictions made on the basis of the dispersive Tavis-Cummings Hamiltonian. We study this system with the goal of realizing a hybrid between superconducting circuits and Rydberg atoms. We measure maximal collective coupling strengths of 1 MHz, corresponding to 3*10^3 Rydberg atoms coupled to the cavity. As expected, the dispersive shift is found to be inversely proportional to the atom-cavity detuning and proportional to the number of Rydberg atoms. This possibility of measuring the number of Rydberg atoms in a nondestructive manner is relevant for quantitatively evaluating scattering cross sections in experiments with Rydberg atoms.
Behaviour of a spin-1/2 particle in Schwarzschild embedded in an electromagnetic universe

description: The Dirac equation is considered in Schwarzschild black hole immersed in an electromagnetic universe with charge coupling. The equations of the charged spin-1/2 particle is separated into radial and angular equations by adopting the Newman-Penrose formalism. The angular equations obtained are similar to the Schwarzschild geometry. For the radial equations we manage to obtain the one dimensional Schrödinger-type wave equations with effective potentials. Due to the presence of electromagnetic field from the surroundings, the interaction with the charged spin-1/2 is considered. Finally, we study the behaviour of the potentials by plotting them as a function of radial distance and expose the effect of the external parameter, charge and the frequency of the particle on them.

description: We have experimentally quantified the temporal structural diversity from the coordinate fluctuations of a laser beam propagating through isotropic optical turbulence. The main focus here is on the characterization of the long-range correlations in the wandering of a thin Gaussian laser beam over a screen after propagating through a turbulent medium. To fulfill this goal, a laboratory-controlled experiment was conducted in which coordinate fluctuations of the laser beam were recorded at a sufficiently high sampling rate for a wide range of turbulent conditions. Horizontal and vertical displacements of the laser beam centroid were subsequently analyzed by implementing the symbolic technique based on ordinal patterns to estimate the well-known permutation entropy. We show that the permutation entropy estimations at multiple time scales evidence an interplay between different dynamical behaviors. More specifically, a crossover between two different scaling regimes is observed. We confirm a transition from an integrated stochastic process contaminated with electronic noise to a fractional Brownian motion with a Hurst exponent H = 5/6 as the sampling time increases. Besides, we are able to quantify, from the estimated entropy, the amount of electronic noise as a function of the turbulence strength. We have also demonstrated that these experimental observations are in very good agreement with numerical simulations of noisy fractional Brownian motions with a well-defined crossover between two different scaling regimes.

description: Data collection and analysis have been the core of Business Intelligence (BI) for many years. The process of using data will only grow with the rise of Industry 4.0, because partial factors such as big data, make it possible to gain more data at a faster rate. This makes it possible to gain a competitive edge over other companies. Currently, there is a need for a new framework which measures value creation of BI decision making within the logistics industry, since existing frameworks are not capable of doing so. Literature review has been conducted and shows that research falls short in measuring the value creation of BI. This study makes use of literature review with two objectives in mind: getting a better understanding of value creation through BI in the logistics industry and metrics/frameworks which are used for measuring value creation. Business research is essential since implementing BI is a costly task and it should be clear on how companies can benefit from BI.
ALMA witnesses assembly of first galaxies
Creators: name: Carniani, Stefano
Publisher: name: Zenodo
Year: 2020

description: Characterizing the primeval galaxies of the Universe entails the challenging goal of observing galaxies with modest star formation rates (< 100 Msun/yr) and approaching the beginning of the reionisation epoch (z > 6). To date a large number of primeval galaxies have been identified thanks to deep near IR surveys. However, to further our understanding on the formation and evolution of such primeval objects, we must investigate their nature and physical properties through multi-band spectroscopic observations. Information on dust content, metallicity, interactions with the surrounding environment, and outflows can be obtained with ALMA observations of FIR fine structure lines such as the [CII] at 158 um and [OIII] at 88 um. ALMA observations reveal that the [OIII] and [CII] emission in z$>$5 star-forming galaxies are partly clumpy and partly diffuse on scales larger than 1kpc. Our analysis reveal that 9 out of 21 galaxies having ALMA [CII] detection break into multiple components and only a fraction of which, if any, are associated with the primary rest-frame UV components, while the bulk of the [CII] emission is associated with fainter rest-frame UV components, or not associated with any UV counterparts at the current limits at all. By taking into account the presence of all these sub-components, we found that the L[CII]-SFR relation in the early epoch has a dispersion two times larger than that observed in the local population. This dispersion reflects the heterogeneous properties of the primeval galaxies. We find that the [CII] luminosity is lower in high Lyα equivalent width (EW) sources than those with high Lyα EW, suggesting that the metallicity plays an important role on the [CII] emission as also expected by recent simulations. The angular resolution of ALMA observations has also allow us to investigate the relation between [CII] surface brightness and star formation rate density. Finally we discuss that the complex properties revealed by ALMA in z>5 galaxies are consistent with expectations by recent models and cosmological simulations, in which differential dust extinction, differential excitation and different metal enrichment levels, associated with different subsystems assembling a galaxy, are responsible for the various appearance of the system when observed with distinct tracers.

description: The collective decay of excitons from initial Bose-Einstein condensate state is investigated theoretically. As practically more interesting case we consider excitons of the yellow series in the semiconductor cuprous oxide where we have collective photon and phonon assisted decay of excitons. It is shown that because of intrinsic instability of recoilless two-boson decay of Bose-Einstein condensate, the spontaneously emitted bosonic pairs are amplified leading to an exponential buildup of a macroscopic population into the certain modes. The collective decay rate has a nonlinear dependence on the excitonic density being comparable or larger than Auger recombination loss rate up to the high densities, which makes obtainable its observation. The considering phenomenon can also be applied for the realization of phonon laser.

Solar fuels production from splitting water with sunlight

description: Today, with the increasing depletion of fossil fuels, and the aggarvating influence of environmental issues, hydrogen fuel has obtained more and more attention from the public due to its attribute as a clean and producible energy source. However, the best approach to produce hydrogen is yet to be discovered, which is why utilisation of hydrogen fuel is as yet so insignificant. The approach of producing hydrogen fuel by splitting water under sunlight has been considered a very promising approach, as it used sunlight , a kind of free and renewable energy source, to produce hydrogen fuel. In this thesis, photocatalysts such as carbon nitride nanotubes (C3N4 NTs). cobalt/carbon nitride nanotubes (Co/C3N4 NTs) and nickel /carbon nitride nanotubes (Ni/C3N4 NTs) with different weight percentages were used to boost the hydrogen production process. The loading with metals has the effect of reducing the recombination rate of electron-hole pairs and enhancing the absorption capacity of the photocatalyst. Of these photocatalysts, 5wt% Co/C3N4 NTs is proven to have the greatest photocatalytic performance when compared with host photocatalyst C3N4 NTs and other Co/C3N4 NTs; and 5wt% of Ni/C3N4 NTs is proven to have the greatest photocatalytic performance when compared with host photocatalyst C3N4 NTs and other Ni/C3N4 NTs. In order to understand the characterisations of the host photocatalys C3N4 NTs, loaded photocatalysts Co/C3N4 NTs and Ni/C3N4 NTs, the morphology morphology of the photocatalysts is analysed by the transmission electron microscope (TEM), and the crystal phase of the photocatalysts is determine4d by X-ray diffraction (XRD).

description: Superconductivity occurs in the proximity of other competing orders in a wide variety of materials. Such competing phases may reveal themselves when superconductivity is locally suppressed by a magnetic field in the core of a vortex. We explore the competition between superconductivity and charge density wave order in the attractive Hubbard model on a square lattice. Using Bogoliubov-deGennes mean field theory, we study how vortex structures form and evolve as the magnetic flux is tuned. Each vortex seeds a CDW region whose size is determined by the energy cost of the competing phase. The vortices form a lattice whose lattice parameter shrinks with increasing flux. Eventually, their charge-ordered vortex cores overlap, leading to a field-driven coexistence phase exhibiting both macroscopic charge order and superconductivity -- a `supersolid'. Ultimately, superconductivity disappears via a first-order phase transition into a purely charge ordered state. We construct a phase diagram containing these multiple ordered states, using $t'$, the next-nearest neighbour hopping, to tune the competition between phases.

The hydro-geomorphic structure and function of temperate upland swamps in eastern Australia
Creators: name: Cowley, Kirsten L.
Publisher: name: Macquarie University

Subjects: Other education not elsewhere classified

description: Geomorphic structure provides the basis that underpins abiotic ecosystem function. Changes in abiotic structure result in profound changes to key functions such as water and carbon storage. Temperate Highland Peat Swamps on Sandstone (THPSS) are a type of upland wetland found in the headwaters of low order streams on the plateau regions of eastern Australia. Similar to fens in the Northern Hemisphere, they are valley bottom swamps and, like their Northern Hemisphere counterparts, have been subject to anthropogenic impacts resulting in changes to both their structure and function. This thesis examines the importance of geomorphic structure to THPSS abiotic functions such as water and carbon storage. THPSS sedimentology comprises organic sandy sediments with high carbon content and peat forming potential, which is inter-related with their high water tables. Depending on swamp/catchment structural characteristics, these systems can be either primarily rainwater - fed or derive some of their water from surrounding groundwater. Hydrological regimes of intact systems are relatively stable, acting as water storage features in the landscape and consistently contributing to downstream base flows. However, once these systems incise and become channelised fills, their function as a water storage system declines, with lowered water holding capacity in the altered swamp sediment contributing to water table drawdowns with concomitant increases in swamp discharges, transforming these systems from a water storage zone into a water throughflow system. In their intact state, THPSS are effective carbon stores with high carbon to nitrogen ratios and low rates of fluvial carbon exports. Once these systems become channelised, their ability to store carbon is compromised, with high volumes of carbon being exported out of the system via the channel, decreasing the carbon content of swamp sediment. This reduced functional capacity in channelised fills emphasises the importance of assessing, monitoring, conserving and restoring the geomorphology of these systems to protect and restore the abiotic functions of these endangered ecological communities

description: In this letter, we apply previous array receiver architecture which employs time-domain sub-Nyquist sampling techniques to jointly estimate frequency and direction-of-arrival(DOA) of narrowband far-field signals. Herein, a more general situation is taken into consideration, where there may be more than one signal in a subband. We build time-space union model, analyze the identification of the model, and give the maximum signal number which can be classified. We also proof that the Cramer-Rao Bound (CRB) is lower than that of which employs Nyquist sampling. Simulation results verify the capacity to estimate the number of sources. Meanwhile, simulations show that our estimation performance closely matches the CRB and is superior for more sources than sensors, especially when the minimum redundancy array (MRA) is employed.

description: Light has profoundly impacted modern medicine and healthcare, with numerous luminescent agents and imaging techniques currently being used to assess health and treat diseases. As an emerging concept in luminescence, aggregation-induced emission (AIE) has shown great potential in biological applications due to its advantages in terms of brightness, biocompatibility, photostability, and positive correlation with concentration. This review provides a comprehensive summary of AIE luminogens applied in imaging of biological structure and dynamic physiological processes, disease diagnosis and treatment, and detection and monitoring of specific analytes, followed by representative works. Discussions on critical issues and perspectives on future directions are also included. This review aims to stimulate the interest of researchers from different fields, including chemistry, biology, materials science, medicine, etc., thus promoting the development of AIE in the fields of life and health.
title: Developing bone marrow organoids as an in vitro model for hematopoietic malignancies
Creators: name: Tenorio Araujo, Emanuel Isaias

description: Eythropoese ist der mehrstufige Prozess, der zur Bildung von roten Blutkörperchen führt. Dieser Prozess ist abhängig von hämatopoetischen Stammzellen (HSC) und ihrer einzigartigen Fähigkeit zur Selbsterneuerung und Differenzierung in verschiedene Linien. Wenn diese Fähigkeit gestört ist, kann dies zu schweren Krankheiten wie Leukämie oder Anämie führen. Obwohl verschiedene Studien die hämatopoetische Dynamik und die erythroide Reifung im erwachsenen Knochenmark aufgedeckt haben, ist aufgrund des begrenzten Zugangs und ethischer Beschränkungen nicht viel über die Dynamik im sich entwickelnden menschlichen Knochenmark bekannt. In dieser Studie stellen wir neuartige humane BMOs vor, die erfolgreich erythroide Zellen einführen und teilweise die Mikroumgebung des Knochenmarks nachahmen, um deren Reifung sowie die Differenzierung anderer hämatopoetischer Zelltypen zu unterstützen. BMOs hatten eine ausgeprägte embryonale und fetale Hämoglobinproduktion und wiesen verschiedene Stadien der Erythropoese auf, mit erythroiden Zellen, die in endothelialen Gefäßen zu finden waren. Wir charakterisierten und analysierten das erythroide Kompartiment, die räumliche und zelluläre Architektur der Organoide und ihre Fähigkeit zur Selbsterhaltung. Diese Organoide sind ein leistungsfähiges und nützliches In-vitro-Modell zur Untersuchung von Krankheiten, zur Vertiefung der Erythroiden- und HSC-Forschung und zur Durchführung neuer pharmakologischer Untersuchungen.
description: Eythropoiesis is the multistep process that leads to red blood cells production. This process is dependent on hematopoietic stem cells (HSCs) and their unique capacity to self-renew and differentiate into distinct lineages. When this capacity is disturbed, it can result in severe disease such as leukaemia or anaemia. Although various studies have unveiled hematopoietic dynamics and erythroid maturation within the adult bone marrow, due to limited access and ethical constraints, not much is known about the dynamics occuring in the developing human bone marrow. In this study, we present novel human BMOs, which successfully introduce erythroid cells and partially mimic bone marrow microenvironment to support their maturation, as well as differentiation of other hematopoietic-derived cell types. BMOs had a prevalent embryonic and fetal hemoglobin production and portrayed different stages of erythropoiesis, with erythroid cells that could be found within endothelial vessels. We characterized and analysed the erythroid compartment, the organoids spatial and cell architecture, and their self- maintenance ability. These organoids represent a powerful and useful in vitro model to study disease, deepen erythroid and HSCs research and perform new pharmacological screenings.

description: In this work, we use player behavior during the closed beta test of the MMORPG ArcheAge as a proxy for an extreme situation: at the end of the closed beta test, all user data is deleted, and thus, the outcome (or penalty) of players' in-game behaviors in the last few days loses its meaning. We analyzed 270 million records of player behavior in the 4th closed beta test of ArcheAge. Our findings show that there are no apparent pandemic behavior changes, but some outliers were more likely to exhibit anti-social behavior (e.g., player killing). We also found that contrary to the reassuring adage that "Even if I knew the world would go to pieces tomorrow, I would still plant my apple tree," players abandoned character progression, showing a drastic decrease in quest completion, leveling, and ability changes at the end of the beta test.

Relativistic theory of magnetic inertia in ultrafast spin dynamics

description: The influence of possible magnetic inertia effects has recently drawn attention in ultrafast magnetization dynamics and switching. Here we derive rigorously a description of inertia in the Landau-Lifshitz-Gilbert equation on the basis of the Dirac-Kohn-Sham framework. Using the Foldy-Wouthuysen transformation up to the order of $1/c^4$ gives the intrinsic inertia of a pure system through the 2$^{\rm nd}$ order time-derivative of magnetization in the dynamical equation of motion. Thus, the inertial damping $\mathcal{I}$ is a higher order spin-orbit coupling effect, $\sim 1/c^4$, as compared to the Gilbert damping $Γ$ that is of order $1/c^2$. Inertia is therefore expected to play a role only on ultrashort timescales (sub-picoseconds). We also show that the Gilbert damping and inertial damping are related to one another through the imaginary and real parts of the magnetic susceptibility tensor respectively.

description: Learning how to perceive speech contrasts in a second language (L2) is influenced by many factors, including similarity to the first language (L1). Over five days, we trained native English and native Spanish speakers to perceive differences in the voiced Hindi contrast /p/-/ph/ while recording their mismatch negativity (MMN) response before, during, and after training. Our results show that only native Spanish speakers showed a decrease in MMN amplitude following training, suggesting that the nonnative contrast was learned successfully, but this was not the case for native English speakers. This suggests that the acoustic and phonetic organisation of L1 differentially affects how we perceive and learn L2 sounds. We examine our results in the context of L2 learning and speech models, suggesting that further development on the difficulty of learning to perceive L2 speech should include more details on similarity to L1.
