description: The comparison of photoproduction cross sections for $c\bar{c}$ and b-b(bar) in PbPb and pPb collisions can give sensitivity to nuclear shadowing effects. The photoproduction of vector mesons is even more sensitive to the underlying gluon distributions. In this study we present the cross sections and rapidity dependence of the photoproduction of heavy quarks and exclusive production of vector mesons in ultraperipheral pPb and PbPb collisions at the Large Hadron Collider at sqrt(s_NN)=5 TeV and sqrt(s_NN)=2.76$ TeV, respectively. The potentials of using these processes for constraining nuclear gluon shadowing are explored. It is found that photoproduction of $J/ψ$ and $Υ$ in PbPb collisions in particular exhibit very good sensitivity to gluon shadowing.

description: The digitalization is realized through a series of change-bringing projects. For the success of the digitalization, the study of the conditions leading to a greater project success rate is thus interesting. The context in which change happens is as interesting as the change itself, yet an early search of the literature revealed that the literature on change management offers little support for qualitative, context rich studies. This study presents a theoretical model derived from a review of the literature on change management with a focus on digital projects. Qualitative iterative coding of 51 relevant articles led to the definition of nineteen dimensions of change management split into two constructs: the type of change and the type of change management approach. Furthermore, the success of digital projects is defined according to five dimensions. The model is intended to support qualitative empirical studies, the ultimate goal being the discovery of the different ways leading to project success. Therefore, short definitions and lists of keywords that might be employed in speech or written documents to refer to the dimensions are given.

description: Transition edge sensors (TES) have the highest reported efficiencies (>98%) for detection of single photons in the visible and near infrared. Experiments in quantum information and foundations of physics that rely critically on this efficiency have started incorporating these detectors into con- ventional quantum optics setups. However, their range of applicability has been hindered by slow operation both in recovery time and timing jitter. We show here how a conventional tungsten-TES can be operated with jitter times of < 4 ns, well within the timing resolution necessary for MHz clocking of experiments, and providing an important practical simplification for experiments that rely on the simultaneous closing of both efficiency and locality loopholes.

description: Within the framework of ab initio time-dependent density-functional theory (TD-DFT), we propose a static approximation to the exchange-correlation kernel based on the jellium-with-gap model. This kernel accounts for electron-hole interactions and it is able to address both strongly bound excitons and weak excitonic effects. TD-DFT absorption spectra of several bulk materials (both semiconductor and insulators) are reproduced in very good agreement with the experiments and with a low computational cost.

description: Solid-state qubits hold the promise to achieve unmatched combination of sensitivity and spatial resolution. To achieve their potential, the qubits need however to be shielded from the deleterious effects of the environment. While dynamical decoupling techniques can improve the coherence time, they impose a compromise between sensitivity and bandwidth, since to higher decoupling power correspond higher frequencies of the field to be measured. Moreover, the performance of pulse sequences is ultimately limited by control bounds and errors. Here we analyze a versatile alternative based on continuous driving. We find that continuous dynamical decoupling schemes can be used for AC magnetometry, providing similar frequency constraints on the AC field and improved sensitivity for some noise regimes. In addition, the exibility of phase and amplitude modulation could yield superior robustness to driving errors and a better adaptability to external experimental scenarios.

We show that in this model, there exists a rapid contraction regime of classical evolution. We calculate the power spectrum of tensor modes in this scenario. We find that it is blue and its amplitude is typically small, leading to mild constraints on the parameters of the model.

description: Australia's history as a settler colony within the British Empire fundamentally shapes its sense of security within the Indo-Pacific region. Australia has consistently looked outside of its region for security and sought partners on the explicit basis of political, cultural, and ethnic similarity. What role does Australia's history play in shaping its foreign policy? We argue that these choices in foreign policy are inextricable from Australia's history as a settler colony on the farthest reaches of the British Empire. The AUKUS Agreement (AUKUS) is an example of how Australia operates to preserve racial hegemony in the face of non-white threat — real or perceived. This research utilises critical discourse analysis to interrogate elite-level discourse around AUKUS to ascertain the dominant narratives that inform its creation, the issues it seeks to address in Australian security policy, how it is structured by historical narratives of security, and how it functions to structure those narratives going forward. This article seeks to participate in the growing push to decolonise International Relations by illuminating the way Australia is ontologically and epistemologically invested in the preservation of racial hegemony.

description: Recently D. Garcia-Sanches, K. Y. Fong, H. Bhaskaran, S. Lamoreaux, and H. X. Tang [Phys. Rev. Lett. v.109, 027202 (2012)] claimed that the frequency shift of an oscillator under the influence of the residual electric and Casimir forces is best described by the Drude model approach to the Casimir force and excludes the plasma model approach. We demonstrate that calculations in support of this claim are performed incorrectly and that the measured data are in strong disagreement with both theoretical approaches to the Casimir force, thus, suggesting the presence of an unaccounted systematic error in the data.

description: Recent progress on Baade-Wesselink (BW)-type techniques to determine the distances to classical Cepheids is reviewed. Particular emphasis is placed on the near-infrared surface-brightness (IRSB) version of the BW method. Its most recent calibration is described and shown to be capable of yielding individual Cepheid distances accurate to 6%, including systematic uncertainties. Cepheid distances from the IRSB method are compared to those determined from open cluster zero-age main-sequence fitting for Cepheids located in Galactic open clusters, yielding excellent agreement between the IRSB and cluster Cepheid distance scales. Results for the Cepheid period-luminosity (PL) relation in near-infrared and optical bands based on IRSB distances and the question of the universality of the Cepheid PL relation are discussed. Results from other implementations of the BW method are compared to the IRSB distance scale and possible reasons for discrepancies are identified.

description: Several proposals to deal with the dynamics of general relativity involve gauge fixings or the introduction matter fields in terms of which the theory is deparameterized. The resulting theories have true Hamiltonians for their evolution that usually involve square roots, and this poses certain challenges for their implementation as self-adjoint quantum operators. We show in the context of a simple model of totally constrained theory that one can introduce related, well defined operators that reproduce semiclassically the same physics as the original ones, at least for states peaked in the regions of phase space where their associated classical quantities are well defined.

description: We investigate topological transport in a spin-orbit coupled bosonic Mott insulator. We show that interactions can lead to anomalous quasi-particle dynamics even when the spin-orbit coupling is abelian. To illustrate the latter, we consider the spin-orbit coupling realized in the experiment of Lin \textit{et al}. [Nature (London) \textbf{471}, 83 (2011)]. For this spin-orbit coupling, we compute the quasiparticle dispersions and spectral weights, the interaction-induced momentum space Berry curvature, and the momentum space distribution of spin density, and propose experimental signatures. Furthermore, we find that in our approximation for the single-particle propagator, the ground state can in principle support an integer Hall conductivity if the sum of the Chern numbers of the hole bands is nonzero.

description: The equations governing null and timelike geodesics are derived within the 3+1 formalism of general relativity. In addition to the particle's position, they encompass an evolution equation for the particle's energy leading to a 3+1 expression of the redshift factor for photons. An important application is the computation of images and spectra in spacetimes arising from numerical relativity, via the ray-tracing technique. This is illustrated here by images of numerically computed stationary neutron stars and dynamical neutron stars collapsing to a black hole.

description: Next Generation Audio (NGA) codecs offer new features for consumers such as advanced user interactivity, immersive sound and optimized reproduction across different classes of playback devices. Yet, ‘real world’ experience in the application of NGA workflows in classical music production is limited: The realistic depiction of the original concert hall sound and the treatment of elevated sound sources impose challenges when recording and mixing. Besides producing for immersive reproduction systems, sound engineers face new tasks like the integration of user interactivity, ensuring downmix compatibility and loudness consistency. This paper expounds our field test for an NGA production workflow found suitable for complex orchestral music. Using MPEG-H 3D Audio as an example, we recorded three full-length concerts with Gewandhausorchester Leipzig. Among them is the prestigious new year's concert with Beethoven’s 9th symphony conducted by Gewandhauskapellmeister Andris Nelsons. We developed a microphone setup for the immersive recording of classical music in Gewandhaus and achieved convincing results with the recording and mixing strategies presented in this paper. The perceived reverberance in the mixes was found to be realistically relatable to the excellent room sound in the original concert hall. Elevated sources, like the choir and soloists, were clearly depicted as such. For metadata authoring and mastering, MPEG-H production tools were used to regulate loudness, dynamic range and downmix compatibility, targeting playback over loudspeakers and 3D audio soundbars. Additionally, we tested two different approaches for interactivity that are suitable for classical music listeners.

title: Capturing 3D Audio: A pilot study on the spatial and timbral auditory perception of 3D recordings using main-array and front-rear separation in diffuse field conditions
Creators: name: Grab, Janet
Publisher: name: TU Ilmenau
Year: 2019
Subjects: subject: 620

description: This research is a preliminary pilot experiment into the subjectively perceived differences between the recordings resulting from three different 3D microphone arrays: A Bowles-Array (Main-Array) with a vertical coincident heightchannel microphone layer, a Fukada-Tree/Hamasaki-Cube configuration (F/R-Array) and a Hybrid-Array containing the signals from the Bowles-Array main layer and the Hamasaki-Cube height layer. It was hypothesised that the arrays in concern will produce recordings that shall lead each to an increased perception of specific attributes for all sources tested (cello, violin, handpan, djembe, guitar). In order to detect possible patterns in spatial and timbral auditory perception subjective listening tests included direct scale magnitude estimations for the attributes Naturalness, Presence, Preference, Width, Localisation Accuracy, Distance/Depth, Envelopment, Spatial Balance, Room Perception, Vertical Image Shift, Vertical Image Spread, and Vertical Frequency Separation and category scaling for the assessment of timbral attributes. Results suggest that none of the arrays in concern conveyed an increased perception of any of the attributes for all sources, which disproves the hypothesis and indicates a source-dependent performance. Simultaneously patterns in the subject responses have been detected which could be explained through psychoacoustic findings focussing on the correlation of perception between the attributes in question. Furthermore, by trying to explain the obtained differences in auditory perception between the different arrays, some assumptions could be made upon what components of which array could have contributed to a specific perception. These findings could serve as a reference for future experiments in the fields of 3D recording techniques or psychoacoustics.

description: Different software solutions have been developed for the calculation and implementation of ambisonic decoding matrices. The present paper presents and describes a new data file format which can be used as an intermediate between solutions. Currently available software solutions use particular data conventions causing difficult compatibility and exchangeability. In the present work an open-source toolkit is developed for storing, handling and using ambisonic decoding matrices. The toolkit includes tools for conversion from common matrix data conventions to the ADD-format and back, calculating decoding matrices, decoding ambisonic signals and extracting existing matrices from external decoding tools. The new ADD-format and toolkit enables increased flexibility in production workflows and eliminates the drawbacks and limitations regarding compatibility between software solutions.

Under some additional assumptions, the hierarchy obtained applying these reciprocal transformations is also associated to an $F$-manifold with compatible flat structure that we call reciprocal $F$-manifold. We also consider the special case of bi-flat $F$-manifolds $(M,\circ,*,\nabla^{(1)},\nabla^{(2)},e,E)$ and we study reciprocal transformations preserving flatness of both the connections $\nabla^{(1)}$ and $\nabla^{(2)}$ and how they act on corresponding solutions of an augmented Darboux-Egorov system.

description: This paper presents a systematic investigation of optimization strategies for the convolution algorithm. Special attention is given to features relevant for the creation of virtual room acoustics, where the source signal is convolved with a room impulse response signal which has a length of several seconds. Examined were optimizations for the discrete convolution in the time domain and for the partitioned fast convolution in the frequency domain. Applied technologies were usage of AVX instructions, and GPU computing with the OpenCL framework. The results of the various algorithms are evaluated in terms of sample throughput. Various influence factors on the measured performance were identified. It turned out, that even ambitious projects with more than 10 channels and filter response lengths of several seconds may be rendered in real-time with the GPU version of the discrete convolution.

description: The statistical fluctuations in free-space links in the turbulent atmosphere are important for the distribution of quantum signals. To that end, we first study statistics generated by the turbulent atmosphere in an entanglement based free-space quantum key distribution (QKD) system. Using the insights gained from this analysis, we study the effect of link fluctuations on the security and key generation rate of decoy state QKD concluding that it has minimal effect in the typical operating regimes. We then investigate the novel idea of using these turbulent fluctuations to our advantage in QKD experiments. We implement a signal-to-noise ratio filter (SNRF) in our QKD system which rejects measurements during periods of low transmission efficiency, where the measured quantum bit error rate (QBER) is temporarily elevated. Using this, we increase the total secret key generated by the system from 78,009 bits to 97,678 bits, representing an increase of 25.2% in the final secure key rate, generated from the same raw signals. Lastly, we present simulations of a QKD exchange with an orbiting LEO satellite and show that an SNRF will be extremely useful in such a situation, allowing many more passes to extract a secret key than would otherwise be possible.

description: Listeria monocytogenes (Lm) is a pathogenic bacteria able to grow at refrigerated temperatures, widely distributed in the environment and thus susceptible to contaminate various food products of which Ready To Eat (RTE) foods are a particular high-risk category. Regulation (CE) 2073/2005 defines food safety criterion for Lm in RTE foods. To comply with these criterion, food business operators (FBOs) could conduct studies to evaluate the growth of Lm during shelf-life under reasonably foreseeable storage conditions. Thus having knowledge of the temperature of domestic refrigerators (last part of the cold chain of refrigerated products) is a key factor for ensuring food safety. The goal of this study was to gather available data on domestic refrigerator temperatures and to update the European Technical Guidelines for assessing shelf-life of RTE foods related to Lm. For this purpose, the European Union Reference Laboratory for Lm launched an inquiry in 2019 to National Reference Laboratories in order to collect data from national surveys or studies conducted on domestic refrigerator temperatures in the EU. In parallel, a review of scientific literature published from 2002 to 2020 was performed. The 75th and 95th percentiles of refrigerator temperatures were determined from raw data using R software, obtained directly from the person in charge of the study, estimated from graphical representations of the temperature’s distribution or calculated using numerous simulations based on a normal distribution of the temperatures (mean and standard deviation). Data collected from nine national surveys and sixteen scientific publications, show that in EU, domestic refrigerators operate with a mean of 6.2°C and that the mean of the 75th and 95th percentiles were respectively 7.6°C and 9.8°C. Based on these outcomes, the temperature at consumer level integrated in the EURL Lm Technical Guidance Document on challenge tests and durability studies for assessing shelf-life of ready-to-eat foods related to Listeria monocytogenes was revised and decreased from 12°C to 10°C.

description: Molecular imaging refers to a class of noninvasive biomedical imaging techniques with the sensitivity and specificity to image biochemical variations in-vivo. An ideal molecular imaging technique visualizes a biochemical target according to a range of criteria, including high spatial and temporal resolution, high contrast relative to non-targeted tissues, depth-independent penetration into tissue, lack of harm to the organism under study, and low cost. Because no existing molecular imaging modality is ideal for all purposes, new imaging approaches are needed. Here we demonstrate a novel molecular imaging approach, called nanodiamond imaging, that uses nanodiamonds containing nitrogen-vacancy (NV) color centers as an imaging agent, and image nanodiamond targets in pieces of chicken breast. Nanodiamonds can be tagged with biologically active molecules so they bind to specific receptors; their distribution can then be quantified in-vivo via optically-detected magnetic resonance of the NVs. In effect, we are demonstrating Optically-Detected Functional-Electron-Spin-Resonance-Imaging, OD-f-ESRI. By combining optical detection with magnetic resonance, nanodiamond imaging achieves high sensitivity and high spatial resolution. It is absent of the complications of ionizing radiation, and the cost should be similar to all-optical imaging. Because nanodiamond imaging is limited by the depth of optical penetration into tissue to depths of a few cm, nanodiamond imaging should open up new avenues of investigation for applications where high depth penetration is not required, such as in small-animal imaging, tumor margin imaging, sentinel lymph node mapping, and perhaps mammography.

description: Augmented reality has the potential to connect people anywhere, anytime, and provide them with interactive virtual objects that enhance their lives. To deliver contextually appropriate audio for these experiences, a much greater understanding of how users will interact with augmented content and each other is needed. This contribution presents a system for evaluating human behavior and augmented reality device performance in calibrated synthesized environments. The system consists of a spherical loudspeaker array capable of spatial audio reproduction in a noise isolated and acoustically dampened room. The space is equipped with motion capture systems that track listener position, orientation, and eye gaze direction in temporal synchrony with audio playback and capture to allow for interactive control over the acoustic environment. In addition to spatial audio content from the loudspeaker array, supplementary virtual objects can be presented to listeners using motion-tracked unoccluding headphones. The system facilitates a wide array of studies relating to augmented reality research including communication ecology, spatial hearing, room acoustics, and device performance. System applications and configuration, calibration, processing, and validation routines are presented.

description: The paper presents different methods of implementation for Ambisoncs recordings in a wave field synthesis system. Using the Ambisonics B-format, virtual microphone signals are extracted from the recording. The signals thus generated can be placed and reproduced at the corresponding positions in the wave field synthesis system. To further improve the performance of Ambisonics recordings in the system the possibility of sound source localisation using a sound field microphone is explored. With the presented methods it is possible to determine the position of individual recorded sound sources and to create a virtual, aligned microphone signal pointing at the source. Reproducing a single sound source gives good results in the system. When playing multiple sound sources, the problems of ”sweet-spot” based systems arise.

description: We show that, taking a two-dimensional photonic-crystal slab system as an example, surprisingly high quality factors (Q) over 10^5 are achievable, even in the absence of a rigorous photonic-band-gap. We find that the density of in-plane Bloch modes can be controlled by creating additional photon feedback from a finite-size photonic-crystal boundary that serves as a low-Q resonator. This mechanism enables significant reduction in the coupling strength between the bound state and the extended Bloch modes by more than a factor of 40.

description: Compact radio emission provides a reliable method for the detection of low luminosity young stellar objects (YSOs), and is particularly useful for detecting the earliest stages of protostellar evolution where the source itself may still be heavily embedded in its natal dust envelope. For such Class 0 and Class I objects the dominant radio emission mechanism is expected to be free-free, however unlike massive YSOs the way in which this radio emission is produced remains a subject of debate. As larger samples of radio YSOs become available the relationship between the radio luminosity of the Class 0/I population and their wider global properties is now being clarified. Furthermore, the broader scientific applications of such samples are also becoming increasingly apparent. These improved constraints on the nature of the radio emission from YSOs are now contributing to our understanding of not only the evolutionary physics of protostars themselves but also their wider impact on their surroundings. Here we discuss the physics of the radio emission, the emerging relationship between this emission and other properties of YSOs and some of the applications for studies exploiting this emission.

title: The Distribution of Ambisonic and Point Source Rendering to Ethernet AVB Speakers

description: Point source rendering is used by many object-based audio systems to mix audio objects to loudspeaker arrangements. Algorithms such as Distance-Based Amplitude Panning and Vector-Base Amplitude Panning allow for audio objects to have their locations rendered with high precision. It has been shown that in the context of loudspeaker rendering, point sources rendered with Ambisonics are often spatially blurred. However, Ambisonics does have the advantage of being able to create interesting spatial audio effects and ambient scenes can be recorded using Ambisonic microphones. This paper intends to highlight the advantages that may be gained by combining Ambisonics with virtual point source rendering. It is well known that the processing required for rendering both point source and Ambisonics can have a large overhead. To mitigate this, a distributed spatial audio system based on Ethernet AVB and distributed endpoint processors is modified to incorporate both point source rendering and Ambisonics. An example is given of how point source rendering can be integrated with Ambisonics using this system with existing software.

Subjects: DDI

description: Knowing what DDI is and understanding how it works and how to use it can be quite daunting—especially if you are
 not a programmer or coder. DDI can be quite a powerful metadata schema for the social sciences, but understanding
 the basics of it is a prerequisite to learning how to use it. This presentation, given as a workshop at the North American
 DDI user conference April 2019 in Ottawa, Canada, will tell you about the background of DDI, the different tools used
 to interpret it and how it is integrated into a data lifecycle workflow. There will be exercises to help you understand the
 different facets of DDI, thus allowing you to see its potential and power. This is not a technical presentation; it is
 intended for those with no background in DDI. However, if you want a refresher in the whys and wherefores of it, then
 this presentation is also for you.
