description: We discuss the signature of the anomalous breaking of the superconformal symmetry in $\mathcal{N}=1$ super Yang Mills theory, mediated by the Ferrara-Zumino hypercurrent ($\mathcal{J}$) with two vector ($\mathcal V$) supercurrents $(\mathcal{JVV})$ and its manifestation in the anomaly action, in the form of anomaly poles. This allows to investigate in a unified way both conformal and chiral anomalies. The analysis is performed in parallel to the Standard Model, for comparison. We investigate, in particular, massive deformations of the $\mathcal{N}=1$ theory and the spectral densities of the anomaly form factors which are extracted from the components of this correlator. In this extended framework it is shown that all the anomaly form factors are characterized by spectral densities which flow with the mass deformation. In particular, the continuum contributions from the two-particle cuts of the intermediate states turn into into poles in the zero mass limit, with a single sum rule satisfied by each component. Non anomalous form factors, instead, in the same anomalous correlators, are characterized by non-integrable spectral densities. These tend to uniform distributions as one moves towards the conformal point, with a clear dual behaviour. As in a previous analysis of the dilaton pole of the Standard Model, also in this case the poles can be interpreted as signaling the exchange of a composite dilaton/axion/dilatino (ADD) multiplet in the effective Lagrangian.[...]

description: In team sports, players search their environments to gain situational awareness regarding the current context. Detecting task-relevant information is necessary to effectively work with others and facilitate task success. This study explored how changes in access to task-relevant information influenced the performance and behavioural coordination of participants performing a complex, online multiagent herding task. The task required teams of three players to work together to locate, corral and contain a herd of autonomous target agents in a desert-like environment. Teams had a maximum of five minutes to complete the task, with task success achieved if a team corralled and contained all target agents within a defined containment region for five seconds. Task manipulations included whether participants' local field of view was obscured by fog (present vs. absent) and whether they had access to global information via a heads-up display (HUD) (Local vs. Global), as well as the Number of Target agents to be corralled (9 vs. 18). Thirty (16 Females) participants ranging in age from 18-45 (Mean = 23.19, SD = 4.71) were recruited for the study and were combined into ten, three-person teams, with participants playing the online game remotely (at home) using their own personal computer. Each team completed four 90-minute sessions, with each session involving 16 five-minute trials per session – two trials for each 2 (Visibility) × 2 (HUD) × 2 (Number of Targets) configurations. Here we explored and compared team performance between Sessions 1 and 4 only. As expected, the results revealed that teams achieved higher levels of performance and behaved in more coordinated and prospective manner when they had greater access to either local (first-person) or global task information. Furthermore, team performance improved over session, with players better utilising the different sources of task information across session. We also found that when teams' access to information was severely impoverished, a 'Sentinel' role emerged to accommodate for the information gap and facilitate the maintenance of teams' situational awareness. These findings are discussed with regard to how task information constrains the behavioural movements and search strategies of players during cooperative online multiplayer team gaming settings.

description: We analyze the anisotropic two dimensional galaxy correlation function (2DCF) of the CMASS galaxy sample from the Sloan Digital Sky Survey Data Release 9 (DR9) of the Baryon Oscillation Spectroscopic Survey (BOSS) data. Modeling the 2DCF fully including nonlinear effects and redshift space distortions (RSD) in the scale range of 30 to 120 h^{-1}Mpc, we find H(0.57)r_s(z_d)/c=0.0444 +/- 0.0019, D_A(0.57)/r_s(z_d)=9.01 +/- 0.23, and f_g(0.57)σ_8(0.57)=0.474 +/- 0.075, where r_s(z_d) is the sound horizon at the drag epoch computed using a simple integral, and f_g(z) is the growth rate at redshift z, and σ_8(z) represents the matter power spectrum normalization on 8h^{-1}Mpc scale at z. We find that the scales larger than 120 h^{-1}Mpc are dominated by noise in the 2DCF analysis, and that the inclusion of scales 30-40 h^{-1}Mpc significantly tightens the RSD measurement. Our measurements are consistent with previous results using the same data, but have significantly better precision since we are using all the information from the 2DCF in the scale range of 30 to 120 h^{-1}Mpc. Our measurements have been marginalized over sufficiently wide priors for the relevant parameters; they can be combined with other data to probe dark energy and gravity.

description: Graphynes are novel two-dimensional carbon-based materials that -due to their nanoweb-like structure- have been proposed as molecular filters, especially for water purification technologies. In this work we carry out first principles electronic structure calculations at the MP2C level of theory to assess the interaction between water and graphyne, graphdiyne and graphtriyne pores. The computed penetration barriers suggest that water transport is unfeasible through graphyne while being unimpeded for graphtriyne. Nevertheless, for graphdiyne, which presents a pore size almost matching that of water, a low barrier is found which in turn disappears if an active hydrogen bond with an additional water molecule on the opposite side of the opening is taken into account. These results support the possibility of using graphtriyne as an efficient membrane for water filtration but, in contrast with previous determinations, they do not exclude graphdiyne. In fact, the related first principles penetration barrier leads to water permeation probabilities which are at least two order of magnitude larger than those estimated by employing commonly used force fields. A new pair potential for the water--carbon non-covalent component of the interaction has been built and it is recommended for molecular dynamics simulation involving graphdiyne and water.

description: Abstract 
The issue of corruption is attracting the attention of all citizens. In Vietnam as well as other countries, it is very difficult to accurately assess the situation of corruption that takes place in practice, because corruption is like an iceberg at sea, often only partially aware of the surface through cases that have been discovered and handled. Through the results of the detection and handling of corruption cases in 2021 and based on the assessment of the authorities, the situation of corruption in Vietnam is serious. Corruption is also quite common in the relationship between public servants and people and businesses, between employees of public service establishments and customers, causing tension in public opinion. This article analyzes the consequences of corruption in the health sector in Vietnam, which has just been published by media outlets. This is very serious in the context of Vietnam using huge financial resources to respond to the 4th wave of Covid.

description: Augmented reality head-up displays (AR HUD) can be seen as a promising advancement of conventional head-up displays in vehicles. Information can be displayed in a contact analogue way in the real world by projecting it onto the vehicle’s windshield. Two major challenges for concept developers are to reduce masking caused by augmented reality (AR) content and to create concepts that work with the limited field of view (FOV). To examine these two challenges, we designed two contact analogue navigation concepts. We compared them to each other in a field study with a prototype car that contained a complete AR HUD testing environment. The participants were experts in interaction design, AR, HUDs, design, and sales. The experiment showed that the application of Gestalt Principles for AR HUD concept design to reduce masking can be a promising approach. In addition, suggestions for further improvement of contact analogue navigation concepts were collected.

description: Galactic encounters are usually marked by a substantial increase of synchrotron emission of the interacting galaxies compared to the typical emission from similar isolated galaxies. This is believed to be associated with an increase of the star formation rate and the associated turbulent magnetic fields. The regular magnetic field is usually believed to decrease. We consider a simple, however rather realistic, mean-field galactic dynamo model where the effects of small-scale generation are represented by random injections of magnetic field from star forming regions. We represent an encounter by the introduction of large-scale streaming velocities and by an increase in small-scale magnetic field injections. The latter describes the effect of an increase of the star formation rate caused by the encounter. We demonstrate that large-scale streaming, with associated deviations in the rotation curve, can result in an enhancement of the anisotropic turbulent (ordered) magnetic field strength, mainly along the azimuthal direction, leading to a significant temporary increase of the total magnetic energy during the encounter; the representation of an increase in star formation rate has an additional strong effect. In contrast to expectations, the large-scale (regular) magnetic field structure is not significantly destroyed by the encounter. It may be somewhat weakened for a relatively short period, and its direction after the encounter may be reversed. The encounter causes enhanced total and polarized emission without increase of the regular magnetic field strength. The increase of synchrotron emission caused by the large-scale streaming can be comparable to the effect of the increase of the star formation rate, depending on the choice of parameters.The effects of the encounter on the total magnetic field energy last only slightly longer than the duration of the encounter (ca. 1 Gyr).

description: We discuss asymptotic solutions of the kinematic $αω$-dynamo in a thin disc (slab). Focusing upon the strong dynamo regime, in which the dynamo number $D$ satisfies $|D|\gg1$, we resolve uncertainties in the earlier treatments and conclude that some of the simplifications that have been made in previous studies are questionable. Comparing numerical solutions with asymptotic results obtained for $|D|\gg1$ and $|D|\ll1$ we find that the asymptotic solutions give a reasonably accurate description of the dynamo even far beyond their formal ranges of applicability. Indeed, our results suggest a simple analytical expression for the growth rate of the mean magnetic field that remains accurate in the range $-200< D< -10$ (which is appropriate for dynamos in spiral galaxies and accretion discs). Finally, we analyse the role of various terms in the dynamo equations to clarify the fine details of the dynamo process.

description: Application of the effective action approach to amplitudes with loop integration is studied for collisions on two and three centers with possible gluon emission. A rule is formulated for the integration around pole singularities in the induced vertices which brings the results in agreement with the QCD. It is demonstrated that the amplitudes can be restored from the purely transverse picture by introducing the standard Feynman propagators for intermediate gluons and quarks.

description: We use the SDSS/DR8 galaxy sample to study the radial distribution of satellite galaxies around isolated primaries, comparing to semi-analytic models of galaxy formation based on the Millennium and Millennium-II simulations. SDSS satellites behave differently around high- and low-mass primaries: those orbiting objects with $M_*>10^{11}M_\odot$ are mostly red and are less concentrated towards their host than the inferred dark matter halo, an effect that is very pronounced for the few blue satellites. On the other hand, less massive primaries have steeper satellite profiles that agree quite well with the expected dark matter distribution and are dominated by blue satellites, even in the inner regions where strong environmental effects are expected. In fact, such effects appear to be strong only for primaries with $M_* > 10^{11}M_\odot$. This behaviour is not reproduced by current semi-analytic simulations, where satellite profiles always parallel those of the dark matter and satellite populations are predominantly red for primaries of all masses. The disagreement with SDSS suggests that environmental effects are too efficient in the models. Modifying the treatment of environmental and star formation processes can substantially increase the fraction of blue satellites, but their radial distribution remains significantly shallower than observed. It seems that most satellites of low-mass primaries can continue to form stars even after orbiting within their joint halo for 5 Gyr or more.

description: Due to the increased popularity of herbomineral preparations in the healthcare sector, a new proprietary herbomineral formulation was formulated consisting of ashwagandha root extract and three minerals viz. zinc chloride, magnesium gluconate, and sodium selenate. The objective of the study was to evaluate the in vitro effect of Biofield Energy Healing (The Trivedi Effect®) on the test formulation using murine splenocyte cells. The herbomineral formulation was divided into two parts; one defined as the control, while the other part was treated with the Biofield Energy Healing Treatment performed from a remote distance by twenty renowned Biofield Energy Healers (The Trivedi Effect®) and defined as the Biofield Treated formulation. The splenocyte cells were exposed to test formulations at concentration from 0.00001053 to 10.53 µg/mL and were analyzed after 48 hours for cell viability using MTT assay. The expression of the cytokines (TNF-α, IFN-γ, IL-1β, and MIP-1α) was determined using ELISA assay. The cell viability data showed that all the tested concentration ranges were found to be safe with percentage cell viability at more than 80%. Further, TNF-α expression was significantly inhibited in the Biofield Treated test formulation group with respect to the vehicle control, while at 0.001053 and 0.1053 µg/mL, the expression was suppressed by 1.70% and 8.16%, respectively in the Biofield Treated test formulation compared to the untreated formulation. However, a significant immunosuppression was reported in IFN-γ expression at 0.00001053, 0.0001053, 0.01053, 0.1053, and 1.053 µg/mL by 12.63%, 2.31%, 8.31%, 9.15%, and 7.86%, respectively in the Biofield Treated test formulation compared with the untreated test formulation. The MIP-1α expression was inhibited by 8.31%, 21.53%, and 8.70% at 0.0001053, 0.01053, and 0.1053 µg/mL, respectively in the Biofield Treated formulation compared with the untreated test formulation. However, IL-1β expression was significantly suppressed by 19.72% at concentration 0.00001053 µg/mL in the Biofield Treated test formulation compared with the untreated test formulation. Thus, the down-regulation of tested cytokines and chemokines in the Biofield Energy Healing test formulation might be applicable for controlling acute and chronic inflammation in many clinical diseases. Overall, the results demonstrated that The Trivedi Effect®- Biofield Energy Healing (TEBEH) has the capacity to potentiate the immunomodulatory activity of the test formulation, which can be useful against autoimmune disorders. Biofield Treated Test formulation may also be useful in anti-aging, anti-inflammatory, stress management and in preventing immune-mediated tissue damage in organ transplants by improving overall health and quality of life.

description: Exploring the ICM power spectrum can help us to probe the physics of galaxy clusters. Using high-resolution 3D plasma simulations, we study the statistics of the velocity field and its relation with the thermodynamic perturbations. The normalization of the ICM spectrum (density, entropy, or pressure) is linearly tied to the level of large-scale motions, which excite both gravity and sound waves due to stratification. For low 3D Mach number M~0.25, gravity waves mainly drive entropy perturbations, traced by preferentially tangential turbulence. For M>0.5, sound waves start to significantly contribute, passing the leading role to compressive pressure fluctuations, associated with isotropic (or slightly radial) turbulence. Density and temperature fluctuations are then characterized by the dominant process: isobaric (low M), adiabatic (high M), or isothermal (strong conduction). Most clusters reside in the intermediate regime, showing a mixture of gravity and sound waves, hence drifting towards isotropic velocities. Remarkably, regardless of the regime, the variance of density perturbations is comparable to the 1D Mach number. This linear relation allows to easily convert between gas motions and ICM perturbations, which can be exploited by Chandra, XMM data and by the forthcoming Astro-H. At intermediate and small scales (10-100 kpc), the turbulent velocities develop a Kolmogorov cascade. The thermodynamic perturbations act as effective tracers of the velocity field, broadly consistent with the Kolmogorov-Obukhov-Corrsin advection theory. Thermal conduction acts to damp the gas fluctuations, washing out the filamentary structures and steepening the spectrum, while leaving unaltered the velocity cascade. The ratio of the velocity and density spectrum thus inverts the downtrend shown by the non-diffusive models, allowing to probe the presence of significant conductivity in the ICM.

description: The complex dimension of the space of exactly marginal deformations for quiver CFTs dual to IIB theory compactified on $Y^{p,q}$ is known to be generically three. Simple general formulas already exist for two of the exactly marginal directions in the space of couplings, one of which corresponds to the sum of the (inverse squared of) gauge couplings, and the other to the $β$-deformation. Here we identify the third exactly marginal direction, which is dual to the modulus $\int B_{2}$ on the gravity side. This identification leads to a relation between the field theory gauge couplings and the vacuum expectation value of the gravity modulus that we further support by a computation related to the chiral anomaly induced by added fractional branes. We also present a simple algorithm for finding similar exactly marginal directions in any CFT described by brane tiling, and demonstrate it for the quiver CFTs dual to IIB theory compactified on $L^{1,5,2}$ and the Suspended Pinch Point.

description: The solvent-free preparation of unsymmetrical N-aryl-5,6-unsubstituted-1,4-dihydropyridines (DHPs) by ball-milling was investigated. Three different mechanochemical domino reactions (one-pot/one step or stepwise) were studied, the process parameters underlying any mechanochemical process were modulated and the differences with solution-based mechanistic pathways were disclosed. The selection of the most suitable method was driven by the physical state of both the reactants and the intermediates, while the physical state of the final 1,4-DHP directed the choice of the catalyst (Lewis vs Brønsted) and the type of work-up to recover the final products (by column chromatography vs precipitation in water). The results herein described are unprecedented in the arena of synthetic methods to access diversely substituted 1,4-DHPs, an N-heterocyclic scaffold relevant to both synthetic and medicinal purposes.

description: Abstract
Women are usually not given prominent places, mainly in the working environment, especially in the South Asian context.  However, women have to play dual role in the social context, viz, a homemaker and an employee.  She has to earn not only to satisfy her own self, but also to meet the financial burden of the family; mainly in the poor, middle and upper-middle classes in the Asian context.  The male counterpart in the working environment has a role to support their female counterparts both officially and personally.  This research is done to check the support extended by the co-male workers to the female co-workers in their working environment, with special reference to the Eastern University, Sri Lanka.  The findings of the research are interesting that most of the male workers extend their support to the female co-workers mainly in the personal needs. However, the support is limited in the official works due to many reasons such as promotional related matters. Also, the research found out another interesting thing is that most of the female workers do not like to ask for help – both officially and personally – to their "senior" co-male workers.  The reason they give is to respect the seniors. This is typically a South Asian mentality which is explored in this research.

description: As is well known, in mathematics, any function could be approximated by the Padé approximant. The Padé approximant is the best approximation of a function by a rational function of given order. In fact, the Padé approximant often gives better approximation of the function than truncating its Taylor series, and it may still work where the Taylor series does not converge. In the present work, we consider the Padé approximant in two issues. First, we obtain the analytical approximation of the luminosity distance for the flat XCDM model, and find that the relative error is fairly small. Second, we propose several parameterizations for the equation-of-state parameter (EoS) of dark energy based on the Padé approximant. They are well motivated from the mathematical and physical points of view. We confront these EoS parameterizations with the latest observational data, and find that they can work well. In these practices, we show that the Padé approximant could be an useful tool in cosmology, and it deserves further investigation.

description: The theoretical analysis of many problems in physics, astronomy and applied mathematics requires an efficient numerical exploration of multimodal parameter spaces that exhibit broken ergodicity. Monte Carlo methods are widely used to deal with these classes of problems, but such simulations suffer from a ubiquitous sampling problem: the probability of sampling a particular state is proportional to its entropic weight. Devising an algorithm capable of sampling efficiently the full phase space is a long-standing problem. Here we report a new hybrid method for the exploration of multimodal parameter spaces exhibiting broken ergodicity. Superposition enhanced nested sampling (SENS) combines the strengths of global optimization with the unbiased/athermal sampling of nested sampling, greatly enhancing its efficiency with no additional parameters. We report extensive tests of this new approach for atomic clusters that are known to have energy landscapes for which conventional sampling schemes suffer from broken ergodicity. We also introduce a novel parallelization algorithm for nested sampling.
Contesting ableist narratives in Egyptology: a theoretical recalibration of 'disability' in ancient Egypt

description: Bodily differences, congenital or acquired impairments, ‘disabilities’, genetic conditions and diseases have been a constant phenomenon in human existence, across cultures and throughout time. Yet, ‘disability’ has been largely understudied and undertheorised within the research agendas of some ancient societies, particularly ancient Egypt. Despite the reality of physical variation, much Egyptological research to-date has neglected theoretical engagement in considering the histories and lived experiences of people with potentially disabling conditions, resulting in a predominance of ableist narratives. This observation stands in contrast to other historical disciplines across broader ancient world contexts which have successfully engaged with Disability Studies (DS), Critical Disability Studies (CDS) and embodiment theories. As a means to begin to address this imbalance, this Master of Research employs a historiographical approach to explore the origins and development of Egyptological narratives pertaining to ‘disability’. Further to this, it proposes a way forward via robust theoretical engagement with DS, CDS, embodiment theory and interdisciplinary collaboration. Such an approach is required in order to recalibrate the prevailing ableist tone and direction of some Egyptological research regarding ‘disability’ and people with bodily differences, as well as encourage future research to be more temporally, culturally and socially nuanced and contextualised.

description: The Fields of Experts (FoE) image prior model, a filter-based higher-order Markov Random Fields (MRF) model, has been shown to be effective for many image restoration problems. Motivated by the successes of FoE-based approaches, in this letter, we propose a novel variational model for multiplicative noise reduction based on the FoE image prior model. The resulted model corresponds to a non-convex minimization problem, which can be solved by a recently published non-convex optimization algorithm. Experimental results based on synthetic speckle noise and real synthetic aperture radar (SAR) images suggest that the performance of our proposed method is on par with the best published despeckling algorithm. Besides, our proposed model comes along with an additional advantage, that the inference is extremely efficient. {Our GPU based implementation takes less than 1s to produce state-of-the-art despeckling performance.}

description: The temperature dependence of the resistivity of epitaxial Ba(Fe_(1-x)Co_x)2As2 thin films (with nominal doping x = 0.08, 0.10 and 0.15) has been analyzed and compared with analogous measurements on single crystals taken from literature. The rho(T) of thin films looks different from that of single crystals, even when the cobalt content is the same. All rho(T) curves can be fitted by considering an effective two-band model (with holes and electrons bands) in which the electrons are more strongly coupled with the bosons (spin fluctuations) than holes, while the effect of impurities is mainly concentrated in the hole band. Within this model the mediating boson has the same characteristic energy in single crystals and thin films, but the shape of the transport spectral function at low energy has to be very different, leading to a "hardening" of the electron-boson spectral function in thin films, associated with the strain induced by the substrate.

description: The classical Wilson loop is the gauge-invariant trace of the parallel transport around a closed path with respect to a connection on a vector bundle over a smooth manifold. We build a precise mathematical model of the super Wilson loop, an extension introduced by Mason-Skinner and Caron-Huot, by endowing the objects occurring with auxiliary Graßmann generators coming from S-points. A key feature of our model is a supergeometric parallel transport, which allows for a natural notion of holonomy on a supermanifold as a Lie group valued functor. Our main results for that theory comprise an Ambrose-Singer theorem as well as a natural analogon of the holonomy principle. Finally, we compare our holonomy functor with the holonomy supergroup introduced by Galaev in the common situation of a topological point. It turns out that both theories are different, yet related in a sense made precise.

description: Shape dynamics is a reframing of canonical general relativity in which time reparametrization invariance is "traded" for a local conformal invariance. We explore the emergence of Lorentz invariance in this model in three contexts: as a maximal symmetry, an asymptotic symmetry, and a local invariance.

description: In the present paper we investigate non-perturbatively and self-consistently the structure of neutron stars in $R$-squared gravity by simultaneously solving the interior and exterior problem. The mass-radius relations are obtained for several equations of state and for wide range of the $R$-squared gravity parameter $a$. Even though the deviation from general relativity for nonzero values of $a$ can be large, they are still comparable with the variations due to different modern realistic equations of state. That is why the current observations of the neutron star masses and radii alone can not put constraints on the value of the parameter $a$. We also compare our results with those obtained within the perturbative method and we discuss the differences between them.

description: Туберкулез является опасным бактериальным инфекционным заболеванием, требующим длительного лечения, а также имеющим сопутствующие патологии. В статье авторы осуществляют фармакологический обзор адъювантных фтизиатрических средств. Как результат, в работе формулируется определение адъювантных средств во фтизиатрии, проводится их классификационный анализ с выделением трех классов. Первые два класса образуются лекарствами преимущественно иммунотропного и метаботропного действия, и они заключают в себе большие возможности в плане реализации индивидуализированной патогенетической терапии больного туберкулезом. К третьему классу относятся средства для борьбы с курением и антиоксиданты. В отношении к антиоксидантам рассматриваются перспективы их развития и применения в плане адъювантной (HDT) терапии туберкулеза.

Abstract
The test of speech sound perception in noise (ToSSPiN) - effect of first language, spatial separation and reverberation on speech sound identification
Creators: name: Boyle, Christian John
Publisher: name: Macquarie University
Year: 2022
Subjects: Other education not elsewhere classified

description: Aims: The first aim of the study is to investigate the effect of native language on the ToSSPiN in Australian English, Canadian English, and non-native English-speaking people. The second aim is to investigate the differences in performance on the Test of Speech Sound Perception in Noise (ToSSPiN) in face-to-face and remote delivery modes. The final aim is to determine if each phoneme is equal in difficulty and adjust them so that, on average, each are identified 71% of the time at an identical signal-to-noise ratio. Design: ToSSPiN targets comprised consonant-vowel-consonant-vowel (CVCV) pseudowords (e.g. /tigu/). Distractors comprised CVCVCVCV pseudo-words. Stimuli were presented using an iPad and headphones. Participants were tested face-to-face at Macquarie University with a researcher recording their responses or remotely via Zoom with a testing partner recording the responses. Scoring occurred adaptively to establish a participant’s speech reception threshold (SRT) expressed as dB signal-to-noise ratio. The listening environment was simulated using reverberant and anechoic head-related transfer functions, creating ecologically valid acoustics. The listening environment also varied in whether the distractors were voiced by the same or different voices from the targets. In the baseline ToSSPiN conditions, the targets originated from 0o azimuth. The distractors originated from ±90o, ±67.5o and ±45o in the spatially separated conditions and 0o in the co-located condition. Reverberation impact (RI) was calculated as the SRT (in dB) in the anechoic condition minus the SRT (in dB) in the reverberant condition. Spatial advantage (SA) was calculated as the SRT (in dB) in the spatially separated condition minus the SRT (in dB) in the co-located condition. Samples: SRTs were collected in young adult native Australian-English speakers (n = 24), native Canadian-English speakers (n = 25) or non-native English speakers (n = 34). Results: No significant effects of language occurred for the baseline measures, RI or SA. A small but significant effect of delivery mode occurred for RI, but not for SA or baseline measures. Psychometric functions obtained for individual phonemes differed notably and phonemes required adjustments ranging from -2.0 dB for /t/ to +8.7 dB for /h/ to attain equal intelligibility.
