description: Quantum emulators, owing to their large degree of tunability and control, allow the observation of fine aspects of closed quantum many-body systems, as either the regime where thermalization takes place or when it is halted by the presence of disorder. The latter, dubbed many-body localization (MBL) phenomenon, describes the non-ergodic behavior that is dynamically identified by the preservation of local information and slow entanglement growth. Here, we provide a precise observation of this same phenomenology in the case the onsite energy landscape is not disordered, but rather linearly varied, emulating the Stark MBL. To this end, we construct a quantum device composed of thirty-two superconducting qubits, faithfully reproducing the relaxation dynamics of a non-integrable spin model. Our results describe the real-time evolution at sizes that surpass what is currently attainable by exact simulations in classical computers, signaling the onset of quantum advantage, thus bridging the way for quantum computation as a resource for solving out-of-equilibrium many-body problems.

description: The Djebel Ouarkziz Formation, located in the northern part of the Tindouf Basin, in western Algeria and southern Morocco, is composed mainly of shales with interbedded limestones, dolostones and sandstones. The limestone beds are relatively thin, but are laterally persistent, and can be followed along strike for tens of kilometres. We have identified 19 limestone beds in three main sections; one logged along the road from Assa to Zag, a second in the Tinguiz-Remz Valley, 15 km to the east, and a third section 10 km west of the Assa-Zag road section. Rugose coral assemblages are recorded in most limestone beds, but the stratigraphically higher beds become more diverse However, many rugose genera and species are persistent throughout much of the succession. The oldest coral assemblages are Asbian in age and the youngest coral assemblages indicate a Serpukhovian age, as confirmed by foraminiferal biostratigraphy. The first appearance of rugose corals shows a different pattern than that in northern Moroccan basins; some common genera that first appear in the Asbian and lower Brigantian in northern Morocco and Europe, appear much later, in the upper Brigantian or Serpukhovian in the Djebel Ouarkziz. The genus Kizilia, which is rare in the Upper Viséan in northern Moroccan basins, is, however, abundant in the Tindouf Basin. Interestingly, the occurrence of the genus Lonsdaleia in the Serpukhovian from Djebel Ouarkziz poses a palaeogeographic problem because of its absence in northern Moroccan basins (except as transported elements in Serpukhovian conglomerates). Similarly, Actinocyathus in the Serpukhovian in the Tindouf Basin is not present north of the Anti-Atlas Mountains. A possible coral migration route to the Tindouf Basin may be from the northeast via the Béchar Basin in Algeria, similar to that already inferred for foraminifers and calcareous algae.

description: We present experiments revealing the competing effect of quantum fluctuations and of a coherent seed in the dynamics of a spin-1 Bose-Einstein condensate, and discuss the relevance of a mean-field description of our system. We first explore a near-equilibrium situation, where the mean-field equations can be linearized around a fixed point corresponding to all atoms in the same Zeeman state $m=0$. Preparing the system at this classical fixed point, we observe a reversible dynamics triggered by quantum fluctuations, which cannot be understood within a classical framework. We demonstrate that the classical description becomes accurate provided a coherent seed of a few atoms only is present in the other Zeeman states $m= \pm 1$. In a second regime characterized by a strong non-linearity of the mean-field equations, we observe a collapse dynamics driven by quantum fluctuations. This behavior cannot be accounted for by a classical description and persists for a large range of initial states. We show that all our experimental results can be explained with a semi-classical description (truncated Wigner approximation), using stochastic classical variables to model the quantum noise.

description: The Devonian Kess-Kess mounds, cropping out in the Hamar Laghdad Ridge (SE Morocco), provide a useful case-study for understanding the relationships between the microbial metabolic activities and micrite precipitation in an extreme environment. Very fine dark and white wrinkled laminae record microbial activity and the geochemistry of the organic matter allows the  characterization of the source organisms. The biogeochemical characterization of extracted organic matter was performed through the functional group analyses by FT-IR Spectroscopy. FT-IR parameters indicate a marine origin and low thermal evolution for the organic material. The organic matter is characterized by the presence of stretching ?C=C vibrations attributable to alkene and/or unsaturated carboxylic acids. Preliminary analysis with GC-MS provides evidence for an autochthonous (

Global Examination of the $^{12}$C+$^{12}$C Reaction Data at Low and Intermediate Energies

description: We examine the $^{12}$C+$^{12}$C elastic scattering over a wide energy range from 32.0 to 70.7 MeV in the laboratory system within the framework of the Optical model and the Coupled-Channels formalism. The $^{12}$C+$^{12}$C system has been extensively studied within and over this energy range in the past. These efforts have been futile in determining the shape of the nuclear potential in the low energy region and in describing the individual angular distributions, single-angle 50$^{0}$ to 90$^{0}$ excitation functions and reaction cross-section data simultaneously. In order to address these problems systematically, we propose a potential that belongs to a family other than the one used to describe higher energy experimental data and show that it is possible to use it over this wide energy range. This potential also predicts the resonances at correct energies with reasonable widths.

Nurse educators’ perspectives of teaching culturally diverse nursing students
Creators: name: Pastirik, Pamela Jacqueline
Publisher: name: University of British Columbia

description: Changing demographics in Canadian society are creating an increasingly culturally diverse population. Paralleling these changes is increasing cultural diversity in educational institutions. Educators are challenged with providing education that is culturally sensitive to an increasingly culturally diverse nursing student (CDNS) population. In nursing education and allied health literature insights are given regarding the needs and perspectives of CDNSs, the approaches and strategies to teaching CDNSs and the challenges perceived by educators. In nursing education, there is a dearth of research related to the perspectives of nurse educators regarding teaching CDNSs. The purpose of this study was to explore nurse educators' perspectives of teaching CDNSs. The framework of symbolic interactionism was used as a broad guide to understanding the definitions, strategies and contextual factors related to teaching CDNSs. A generic qualitative design was used to explore these broad theoretical concepts. Seven nurse educators currently teaching in baccalaureate nursing programs were interviewed. Data analysis using the constant comparative method was implemented. Validation regarding the conceptual categories was confirmed through second interviews with the participants. The findings of the study revealed three major categories: 1) Conceptions of Culturally Diverse Nursing Students 2) Challenges to Teaching CDNSs 3) Dealing with Diversity. Teachers generally believed that CDNSs had unique cultural backgrounds, behaviors and beliefs and learning needs that could be uniquely delineated. They believed that language and communication, lack of knowledge and understanding of cultural diversity, lack of resources for teachers and students and a milieu that fostered a pressure to treat students the same, were significant challenges to teaching CDNSs. Approaches to dealing with diversity were identified as examining one's own beliefs and values, considering the influence of culture on the student's performance, and monitoring one's teaching practices. The most significant findings in the study related to the teachers' perceived lack of knowledge, skills and awareness to address the learning needs of CDNSs. The needs of CDNSs, the approaches to teaching CDNSs and the challenges to developing intercultural competency are highlighted.

description: Vehicle detection in aerial videos often requires post-processing to eliminate false detections. This paper presents a spatio-temporal processing scheme to improve automatic vehicle detection performance by replacing the thresholding step of existing detection algorithms with multi-neighborhood hysteresis thresholding for foreground pixel classification. The proposed scheme also performs spatial post-processing, which includes morphological opening and closing to shape and prune the detected objects, and temporal post-processing to further reduce false detections. We evaluate the performance of the proposed spatial processing on two local aerial video datasets and one parking vehicle dataset, and the performance of the proposed spatio-temporal processing scheme on five local aerial video datasets and one public dataset. Experimental evaluation shows that the proposed schemes improve vehicle detection performance for each of the nine algorithms when evaluated on seven datasets. Overall, the use of the proposed spatio-temporal processing scheme improves average F-score to above 0.8 and achieves an average reduction of 83.8% in false positives.

title: 'Þese dowble wordis þat ben hard to vndirstonde': Exploring the Mutability of Medieval Devotional Language through the Theological Concept of Despair
Creators: name: Mill, Celia
Publisher: name: University of Kent
Year: 2021

description: This thesis explores the mutability of medieval devotional language by focusing on the complex and paradoxical concept of spiritual despair. It looks at how writer, translator, interpreter, and ultimate audience might bring different agendas to bear on their own readings. Part one examines a range of Latin texts in which the first chapter examines thirteenth and fourteenth-century pastoral manuals for how their stance on despair alters according to the writers' purpose, intended audience, and the creative readings of intermediaries. Chapter two considers despair from the perspective of eleventh and twelfth-century vita contemplativa monastic writing. It explores the effects language might have on an enclosed community and how authors sometimes altered their approach as a result. The second half of this thesis explores these concepts further through fourteenth-century vernacular devotional writing aimed at the spiritually interested laity. By looking at Middle English, Latin, and Modern English translations of Marguerite Porete's Mirror of Simple Souls, in comparison with Julian of Norwich's Revelations, it reflects on how language is never fixed but always full of several different, sometimes paradoxical, meanings which therefore allow for a range of devotional practices.
Disembodiment of arbitrary number of properties in quantum Cheshire cat experiment

description: The quantum Cheshire cat is an effect demonstrated within the framework of weak measurement aided with post-selection scenario where the property (say, grin) of a quantum particle (the cat) can be found in a spatially separated location from its position. In this work, we first propose interesting variants of quantum Cheshire cat where disembodiment of two different properties of a `cat' is demonstrated, so that, the \emph{grin} and the \emph{meowing} of it can be found in two different paths on an interferometer while the cat is in another path. We further extend this proposal for three-qutrit and $d$-qudit systems of a single particle. We provide sketches of the experimental proposals for testing our scheme by using the path, spin and energy degrees of freedoms of a single neutron and the path, polarization and orbital angular momentum of a single photon.

PETROGRAPHIC ANALYSIS OF TRACE FOSSIL DESMOGRAPTON FUCHS, 1895 FROM THE MIOCENE OF NORTHERN APENNINES (ITALY): A METHODOLOGY TO DETECT HYPICHNIAL FEATURES AND IMPLICATIONS ON THE GRAPHOGLYPTID ETHOLOGY

description: The trace fossil Desmograpton Fuchs, 1895, as many other graphoglyptids, has been considered to be a typical pre-turbidite, three-dimensional burrow system formed in mud and preserved as a casting at the sole of turbidites. This classic interpretation was mostly based on hypichnial preservation, due to the lack of direct evidence (e.g. modern seafloor pictures) for pre-depositional or post-depositional origin. Due to the accidental series of processes invoked to explain the perfect hypichnial preservation of this delicate trace fossil, several doubts and questions have been raised. To try to clarify the sedimentary processed that lead this trace fossil to be preserved, 26 thin sections of Desmograpton dertonensis Sacco, 1888 and Desmograpton ichthyforme Macsotay, 1967 have been performed at sand/clay interface of thin-bedded sandstone turbidites in the Miocene marl deposits of Verghereto, Northern Apennines (Italy). Petrographic analysis of textures and grains of the burrow-filling sediments points out that most of the grains of burrows differ from those of overlying sand, being either more or less sorted and differ in composition and locally also in grain size. Burrows are occasionally characterised by an upper rim, more or less thick, enriched in glauconite, phosphates, pyrite or quartz. Axial cuts of the strings show that rim was involved in diagenetic compaction, squeezing and fluid migration modifying the original shape of the trace fossil. In pre-depositional conditions the oblique-oriented filling is the only explication to preserve the upper rim of original mud, while compaction produced asymmetry in hypichnial tunnels. This petrographic approach, performed for the first time on this graphoglyptid genus, also elucidates the complex interaction of several taphonomic processes that led to the preservation of Desmograpton. The application of a similar petrographic approach to other graphoglyptids could help to better understand their origin, ethology and their preservation processes.

description: With the onset of COVID-19 pandemic, social media has rapidly become a crucial communication tool for information generation, dissemination, and consumption. In this scoping review, we selected and examined peer-reviewed empirical studies relating to COVID-19 and social media during the first outbreak starting in November 2019 until May 2020. From an analysis of 81 studies, we identified five overarching public health themes concerning the role of online social platforms and COVID-19. These themes focused on: (i) surveying public attitudes, (ii) identifying infodemics, (iii) assessing mental health, (iv) detecting or predicting COVID-19 cases, (v) analyzing government responses to the pandemic, and (vi) evaluating quality of health information in prevention education videos. Furthermore, our review highlights the paucity of studies on the application of machine learning on social media data related to COVID-19 and a lack of studies documenting real-time surveillance developed with social media data on COVID-19. For COVID-19, social media can play a crucial role in disseminating health information as well as tackling infodemics and misinformation.

description: We discuss a model of Ferromagnet / Superconductor / Ferromagnet (FSF) double junction in which the quasiparticles are not in equilibrium with the condensate in a region of the superconductor containing the two FS contacts. The role of geometry is discussed, as well as the role of a small residual density of states within the superconducting gap, that allows a sequential tunneling crossed current. With elastic quasiparticle transport and the geometry with lateral contacts, the crossed conductances in the sequential tunneling channel are almost equal in the normal and superconducting phases, if the distance between the FS interfaces is sufficiently small. The sequential tunneling and spatially separated processes (the so-called crossed Andreev reflection and elastic cotunneling processes) lead to different signs of the crossed current in the antiparallel alignment for tunnel interfaces.

description: A complete canonical quantization of the SU(3) Skyrme model performed in the collective coordinate formalism in general irreducible representations. In the case of SU(3) the model differs qualitatively in different representations. The Wess-Zumino-Witten term vanishes in all self-adjoint representations in the collective coordinate method for separation of space and time variables. The canonical quantization generates representation dependent quantum mass corrections, which can stabilize the soliton solution. The standard symmetry breaking mass term, which in general leads to representation mixing, degenerates to the SU(2) form in all self-adjoint representations.

description: An analytical theory of non-uniformly doped or shaped PN-junction diodes submitted to large-signals at high frequencies is presented. The resulting expressions can be useful to evaluate the performance of semiconductor device modeling software. The transverse averaging technique is employed to reduce the three-dimensional charge carrier transport equations into the quasi-one-dimensional form, with all physical quantities averaged out over the longitudinally-varying cross section. Although, it is assumed an axial symmetry, this approach gives rise to useful analytic expressions for the static current--voltage characteristics, the diffusion conductance, and diffusion capacitance as a function of the signal amplitude and the cross section non-uniformity.

DTUrtle – an easily accessible Differential Transcript Usage analysis pipeline
Creators: name: Tekath, Tobias

Publisher: name: F1000 Research Limited
Year: 2019

description: The common differential gene expression (DGE) analysis of RNA-seq data uses gene quantification counts to detect significant expression changes. Since the rise of fast and reliable transcriptomic quantifiers like Salmon and Kallisto, these gene counts are often computed as the sum of the individual counts of the genes transcripts. Complementary to the DEG-analysis, proportional changes in the transcript composition of a gene would be of great interest for many research questions, such as analysis of alternative splicing.

We propose a state-of-the-art RNA-seq pipeline DTUrtle to utilize these transcript counts and analyze the differential transcript usage (DTU). The pipeline combines the pre-processing, quantification and DTU-calling in a user-friendly way and integrates the results in a search- and filterable overview table. DTUrtle focuses on statistical validity and includes some additional filtering steps, proposed by Love et al., to improve the DTU-calling performance as well as the run time for big datasets. The results overview table integrates additional information and visualizations which enables the user to inspect the elements of interest in further detail. DTUrtle has been successfully applied to multiple datasets, including a dataset of 145 human samples.

The pipeline DTUrtle enables researchers to perform DTU-analysis in a comfortable way and facilitates an in-depth inspection of the results. Its easy-to-use Snakemake workflow makes it adaptable and reliable. The novel visualization methods allow for inclusion of additional data and a visual assesment of the results of interest.

Year: 2020

description: The object of this dissertation is to establish the existence and reach of the Socialist Movement for the United States of Europe (SMUSE). The SMUSE was a transnational group of socialists and federalists from a dozen European countries, counting notably Italian Socialist Mario Zagari, French cabinet member André Philip French President Guy Mollet, and Belgian Prime Minister Paul-Henri Spaak. The Movement’s members collaborated actively beginning in 1947 with a view to establishing a supranational European community operating on the basis of democratic majority. Founded in the United Kingdom, it was soon spearheaded by the French, in close collaboration with the French Socialist party. It established a relationship between the internationalist wing of the Labour party and Continental socialists in the late 1940s. In mid-1950 it became deeply involved in the campaign for the European Defense Community and the political umbrella under which the EDC would operate. Beginning in 1955, it functioned as a forum of coordination in the context of the Treaties of Rome. After the establishment of the European Communities, many of its adherents became leading members of the Socialist Group in the European Parliament, and the Movement continued to function as a forum of socialist dialogue and networking into the 1990s.
How do galactic winds affect the Lyalpha forest?

description: We investigate the effect of galactic winds on the Lyalpha forest in cosmological simulations of structure and galaxy formation. We combine high resolution N-body simulations of the evolution of the dark matter with a semi-analytic model for the formation and evolution of galaxies which includes detailed prescriptions for the long-term evolution of galactic winds. This model is the first to describe the evolution of outflows as a two-phase process (an adiabatic bubble followed by a momentum--driven shell) and to include metal--dependent cooling of the outflowing material. We find that the main statistical properties of the Lyalpha forest, namely the flux power spectrum P(k) and the flux probability distribution function (PDF), are not significantly affected by winds and so do not significantly constrain wind models. Winds around galaxies do, however, produce detectable signatures in the forest, in particular, increased flux transmissivity inside hot bubbles, and narrow, saturated absorption lines caused by dense cooled shells. We find that the Lyalpha flux transmissivity is highly enhanced near strongly wind-blowing galaxies, almost half of all high-redshift galaxies in our sample, in agreement with the results of Adelberger et al. (2005). Finally, we propose a new method to identify absorption lines potentially due to wind shells in the Lyalpha forest: we calculate the abundance of saturated regions in spectra as a function of region width and we find that the number with widths smaller than about 1 Angstrom at z=3 and 0.6 Angstrom at z=2 may be more than doubled. This should be detectable in real spectra.

Interference experiment, anomalous weak value and Leggett-Garg test of macrorealism
Creators: name: Pan, A. K.
Publisher: name: arXiv
Year: 2020
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: Macrorealism is a classical world view asserting that the properties of macro-objects exist independently and irrespective of observation. One practical approach to test this view in quantum theory is to observe the quantum coherence for macro-object in an interference experiment. An elegant and conceptually appealing approach for testing the notion of macrorealism in quantum theory is through the violation of Leggett-Garg inequality. However, a conclusive Leggett-Garg test hinges on how the non-invasive measurability criteria is guaranteed in an experiment and remains a debated issue till date. In this work, we connect the practical and the conceptual approaches for testing the macrorealism through the weak value. We argue that whenever quantum effect is observed in an interference experiment there is an existence of anomalous weak value. Further, we demonstrate that whenever such weak value exists, one obtains the violation of a Leggett-Garg inequality in any interference experiment. Since the system itself serves as apparatus in a path-only interference experiment, one cannot salvage the macrorealism by abandoning the non-invasive measurability assumption. We provide a rigorous discussion about the assumptions involved in Leggett-Garg scenario and how our scheme fits into it. Further, using the quasiprobability approach we explain how non-invasive measurability condition is satisfied in our scheme.

description: In the quest to solve the long-standing coronal heating problem, it has been suggested half a century ago that coronal loops could be heated by waves. Despite the accumulating observational evidence of the possible importance of coronal waves, still no 3D MHD simulations exist that show significant heating by MHD waves. Here we report on the first 3D coronal loop model heating the plasma against radiative cooling. The coronal loop is driven at the footpoint by transverse oscillations and subsequently the induced Kelvin-Helmholtz instability deforms the loop cross-section and generates small-scale structures. Wave energy is transfered to smaller scales where it is dissipated, overcoming the internal energy losses by radiation. These results open up a new avenue to address the coronal heating problem.

Eleven nights of observations have made it possible to collect 1293 radial velocity measurements with a standard deviation of about 2.2 m s^-1. The power spectrum of the high precision velocity time series clearly presents several identifiable peaks between 0.7 and 2.4 mHz showing regularity with a large and small spacings of Delta_nu = 72.1 uHz and delta_nu_02 = 6.3 uHz respectively. Thirty-one individual modes have been identified with amplitudes in the range 23 to 46 cm s^-1, i.e. with a signal to noise between 3 and 6.

Rapid Formation of Super-Earths around M Dwarf Stars

Subjects: subject: Astrophysics (astro-ph)

description: While the recent microlensing discoveries of super-Earths orbiting two M dwarf stars have been taken as support for the core accretion mechanism of giant planet formation, we show here that these planets could also have been formed by the competing mechanism of disk instability, coupled with photoevaporative loss of their gaseous envelopes by a strong external source of UV radiation, i.e., an O star. M dwarfs that form in regions of future high-mass star formation would then be expected to have super-Earths orbiting at distances of several AU and beyond, while those that form in regions of low-mass star formation would be expected to have gas giants at those distances. Given that most stars are born in the former rather than in the latter regions, M dwarfs should have significantly more super-Earths than gas giants, as seems to be indicated by the microlensing surveys.

description: We study superradiant scattering off Bose-Einstein condensates by solving the semiclassical Maxwell-Schroedinger equations describing the coupled dynamics of matter-wave and optical fields. Taking the spatial dependence of these fields along the condensate axis into account, we are able to reproduce and explain many of the characteristic features observed in the experiments of Inouye et al. [Science 285, 571 (1999)] and Schneble et al. [Science 300, 475 (2003)], such as the shape of the atomic side-mode distributions for forward and backward scattering, the spatial asymmetry between forward and backward side modes, and the depletion of the condensate center observed for forward scattering.

description: Several studies strongly imply that
      the desert locust (Schistocerca gregaria) is able to use
      polarized light patterns in the sky for orientation tasks. A
      specialized region in its compound eye (DRA) contains
      photoreceptor cells which are morphologically adapted for the
      detection of polarized light. This work focuses on the
      physiological and morphological examination of photoreceptor
      cells inside and outside the DRA. By applying
      electrophysiological methods it was tested for spectral,
      absolute, polarization and angular sensitivity of receptor
      cells by using electrophysiological methods. Tracer
      injections revealed projection patterns of the respective
      cells. In addition data of the solitarious and gregarious
      phase of the desert locusts were compared.
description: Eine Reihe von Studien legt nahe,
      dass die Wüstenheuschrecke (Schistocerca gregaria) dazu in
      der Lage ist Muster von polarisiertem Licht am Himmel für
      Orientierungszwecke zu nutzen. Eine spezialisierte Region in
      ihrem Komplexauge (DRA) enthält Fotorezeptorzellen, welche
      morphologisch an die Detektion von polarisiertem Licht
      angepasst sind. Diese Arbeit beschäftigt sich mit der
      physiologischen und morphologischen Untersuchung von
      Fotorezeptoren innerhalb und außerhalb der DRA. Mittels
      elektrophysiologischer Methoden wurden die spektrale,
      absolute und Polarisationssensitivität sowie die visuellen
      Felder der Rezeptorzellen untersucht. Farbstoffinjektionen
      zeigten Projektionsmuster der jeweiligen Zellen auf.
      Zusätzlich wurden Daten der solitären und gregären Phase der
      Wüstenheuschrecke verglichen.

      verglichen.
description: The present work includes the
      formation and description of four-membered ring systems based
      on organometallic aluminum, gallium and indium compounds as
      well as the silylsubstituted pnicogen compounds of phosphorus
      and arsenic. Their chemical and spectroscopic characteristics
      and the reactivity towards N-heterocyclic carbenes are
      described. Regarding this, the cleavage of the ring systems
      with strong lewis bases is the main topic of this work.
      Therefore the structural and spectroscopic parameters as well
      as the thermal behaviour of the monomeric compounds is
      decribed and compared.

description: In the example of the Schrödinger/KdV equation we treat the theory as equivalence of two concepts of Liouvillian integrability: quadrature integrability of linear differential equations with a parameter (spectral problem) and Liouville's integrability of finite-dimensional Hamiltonian systems (stationary KdV--equations). Three key objects in this field: new explicit $Ψ$-function, trace formula and the Jacobi problem provide a complete solution. The $Θ$-function language is derivable from these objects and used for ultimate representation of a solution to the inversion problem. Relations with non-integrable equations are discussed also.

Device-independent certification of Hilbert space dimension using a family of Bell expressions

description: Dimension witness provides a device-independent certification of the minimal dimension required to reproduce the observed data without imposing assumptions on the functioning of the devices used to generate the experimental statistics. In this paper, we provide a family of Bell expressions where Alice and Bob perform $2^{n-1}$ and $n$ number of dichotomic measurements respectively which serve as the device-independent dimension witnesses of Hilbert space of $2^{m}$ dimensions with $m=1,2..2^{\lfloor n/2\rfloor}$. The family of Bell expressions considered here determines the success probability of a communication game known as $n$-bit parity-oblivious random access code. The parity obliviousness constraint is equivalent to preparation non-contextuality assumption in an ontological model of an operational theory. For any given $n\geq 3$, if such a constraint is imposed on the encoding scheme of the random-access code, then the local bound of the Bell expression reduces to the preparation non-contextual bound. We provide explicit examples for $n=4,5$ case to demonstrate that the relevant Bell expressions certify the qubit and two-qubit system, and for $n=6$ case, the relevant Bell expression certifies the qubit, two-qubit and three-qubit systems. We further demonstrate the sharing of quantum preparation contextuality by multiple Bobs sequentially to examine whether number of Bobs sharing the preparation contextuality is dependent on the dimension of the system. We provide explicit example of $n=5$ and $6$ to demonstrate that number of Bobs sequentially sharing the contextuality remains same for any of the $2^{m}$ dimensional systems.

description: We consider the possibility of an axion-like particle (ALP) that is a ghost, with wrong-sign kinetic and mass terms. Such an ALP can arise as the partner to an ordinary particle in theories with higher-derivative quadratic terms. We compute the photon regeneration probability in light-shining-through-wall experiments and show that the presence of such a ghostly ALP can lead, in principle, to discernible effects.

description: Soft X-ray resonant powder diffraction has been performed at the Mn L2,3 edges of A-site ordered SmBaMn2O6. The energy and polarization dependence of the (1/2 1/2 0) reflection provide direct evidence for a (x2-z2)/(y2-z2) type orbital ordering in contrast to the single layer manganite. The temperature dependence of the reflection indicates an orbital reorientation transition at 210 K, below which the charge and orbital ordered MnO2 sheets show AAAA type of stacking. The concurring reduction of the ferromagnetic super exchange correlations leads to further charge localization.

description: Quantum key distribution (QKD) networks hold promise for sharing secure randomness over multi-partities. Most existing QKD network schemes and demonstrations are based on trusted relays or limited to point-to-point scenario. Here, we propose a flexible and extensible scheme named as open-destination measurement-device-independent QKD network. The scheme enjoys security against untrusted relays and all detector side-channel attacks. Particularly, any users can accomplish key distribution under assistance of others in the network. As an illustration, we show in detail a four-user network where two users establish secure communication and present realistic simulations by taking into account imperfections of both sources and detectors.
