description: Manchester will discuss how diaspora theory applies to the Russian diaspora. Whereas general histories of Global diaspora have ignored the first, and arguably the most significant (in terms of its influence) of the Russian diaspora waves, scholars and the media in post-Soviet Russia have been preoccupied with this previously taboo subject. First wavers are often held up as role models of pre-revolutionary “Russianness” for post-Soviet Russians struggling to repudiate the Soviet past, and the Russian government has aggressively sought the repatriation of émigré archives. In keeping with contemporary Russian nationalism, the virtual explosion in publications and documentaries about First Wavers in post-Soviet Russia has focused on emphasizing their achievements not only to “Russian Abroad” but to the host countries where they lived, including the United States. While the Russian and Soviet empires were, unlike their Western rivals, contiguous, “Russia Abroad” is beginning to serve an odd function for a mainly political diaspora: as a testimony to Russia’s presence and influence abroad as a would-be colonial power.

description: Inspired by the model of Jarvinen and Kiritsis, we present a simple holographic model for the on set of chiral symmetry breaking at the edge of the conformal window in QCD in the Veneziano limit. Our most naive model enforces the QCD two loop running coupling on a D3/D7 holographic brane system. The mass of the holographic field, describing the chiral condensate in the model, is driven below the BF bound when the running is sufficiently strong, triggering chiral symmetry breaking for N_f/N_c<2.9. This model though contains too great a remnant of supersymmetry and does not correctly encode the perturbative anomalous dimensions of QCD. In a second model we impose the QCD anomalous dimension result and find chiral symmetry breaking sets in for N_f/N_c=4 at a BKT-type phase transition. In this case the transition is triggered when the anomalous dimension of the mass operator γ_m=1.

Risikofaktoren sind ein weibliches Geschlecht, vorbestehende Kopfschmerzen und ein Schlaganfall der Kleinhirn-Arterien. Akute und persistierende Kopfschmerzen lassen sich als Kopfschmerz vom Spannungstyp einordnen.
description: The frequency and characteristics of acute headache in 191 patients were consecutively investigated by questionnaire within the first three days after stroke at the Department of Neurology of the University Hospital Halle/Saale, and the long-term course of persistent headache was determined. In summary, it could be shown that headaches after a stroke are a relevant problem. Risk factors are a female gender, pre-existing headaches and a stroke of the cerebellar arteries. Acute and persistent headache can be classified as tension-type headache.

description: Dünnfilme aus MFe2O4 (M = Co, Ni, Mg, Cu) und BaTiO3 wurden durch Rotationsbeschichtung von N,N-Dimethylformamid und Essigsäure Lösungen auf Platin-Silizium und (001) SrTiO3 Substraten hergestellt. Um die gewünschte Schichtdicke zu erhalten wurden diverse Beschichtungsschritte durchgeführt. Röntgendiffraktion, IR- und Ramanspektroskopie zeigten die phasenreine Bildung von Bariumtitanat und der Ferritspinelle. Rasterelektronen- und Rasterkraftmikroskopie belegten eine glatte und homogene Oberfläche mit Rauigkeiten im nm-Bereich für alle Filme. Rocking Curve Messungen offenbarten, dass die Mosaizitäten der Ferrite durch die Platinschicht induziert wurden, bei der die (111)-Netzebenen parallel zur Filmoberfläche liegen. Reziproke Gitterkartierungen demonstrierten das epitaktische Wachstum der BaTiO3 und CoFe2O4 Schicht auf (001) SrTiO3. Polarisationsmessungen und magnetische Hysteresen beweisen das Vorhandensein von Ferroelektrizität und Ferrimagnetismus (Multiferroika).
description: Thin films of MFe2O4 (M = Co, Ni, Mg, Cu) and BaTiO3 were prepared by spin coating of N,N-dimethylformamide and acetic acid solutions on platinum silicon and (001) SrTiO3 substrates. Several coatings steps were applied to get the desired thickness of the films. X-ray diffraction, IR and Raman spectroscopy revealed the formation of phase-pure bariumtitanate and the ferrite spinels. Scanning electron microscopy and atomic-force microscopy investigations reveal smooth and uniform surfaces with root mean square roughness values in the nm range for all fabricated films. Rocking curve scans revealed that the mosaicity of the ferrite films are induced by the Pt-layer with the (111) lattice plane being parallel to the film surface. Reciprocal space mapping clearly demonstrated the epitaxial growth of the BaTiO3 and CoFe2O4 layer on (001) SrTiO3. Polarization measurements and magnetic hysteresis loops prove the presence of ferroelectricity and ferrimagnetism (multiferroics).

description: Effect of rotationally-invariant Hund's rule coupling on a magnetism of multiorbital Hubbard models is studied within a dynamical mean field theory framework. Comparison of static magnetic susceptibilities and local densities of states of two- and three-orbital models of a complete rotationally invariant Coulomb interaction and a "density-density" Hartree type interaction shows the different role of spin-flip interactions for different band fillings. In the particle-hole symmetric case the Mott-Hubbard physics dominates due to the strong effective Coulomb interaction, while for the multiple electronic configurations away from half-filling (two electrons in the three band model) the formation of local magnetic moments due to Hund's exchange interaction becomes the most significant effect for itinerant magnetic systems. A shift of the temperature of magnetic ordering due to the rotationally-invariant Hund's rule coupling is found to be the largest in a three-orbital model with a two-electron occupancy where the single particle spectrum is metallic and is not sensitive to different forms of the Coulomb vertex. A larger enhancement of the effective mass in a model with a rotationally-invariant interaction is discussed. In the half-filled case we find a drastic change in the density of states close to the Mott transition which is related to the spin-flip Kondo fluctuations in a degenerate orbital case, while the corresponding shift of the magnetic transition temperature is relatively small. It is shown that a change in the ground state degeneracy due to a different symmetry of the Coulomb interaction in the density-density model leads to a breakdown of the quasiparticle peak at the Fermi level in the proximity of a Mott transition on the metallic side. We discuss the relevance of rotationally-invariant Hund's interaction in the transition metal magnetism.

description: Merkmale können aufgrund von überlappenden Quantitative Trait Locus (QTL)-Regionen genetisch korreliert sein. Mehrere überlappende QTL-Regionen für den Kornertrag und verschiedene Ertragskomponenten vom Brotweizen (Triticum aestivum L.) wurden durch multivariate Assoziationskartierung detektiert. Für die Mehrheit der überlappenden QTL-Regionen konnte Pleiotropie als genetische Ursache nicht ausgeschlossen werden. Die Unterscheidung zwischen Pleiotropie und enger Kopplung wird von niedrigen Allelfrequenzen und QTL-Größen und einem hohen Kopplungsungleichgewicht zwischen QTL limitiert. Multivariate Ansätze für die genomische Vorhersage der Anfälligkeit gegenüber der Ährenfusariose bei Hybridweizen sind genauer als univariate Modelle wenn der Verwandtschaftsgrad zwischen Trainings- und Validierungspopulationen geringer ist. Verschiedene Selektionsindizes erlauben die kombinierte Verbesserung vom Kornertrag und dem Proteingehalt vom Futterroggen (Secale cereale L.). Die Selektionsindizes können direkt durch die Anwendung von univariaten Modellen vorhergesagt werden.
description: Traits can be genetically correlated because of co-located quantitative trait loci (QTL). A multiple-trait association mapping study in bread wheat (Triticum aestivum L.) revealed that several QTL for yield and its components co-locate. In most genomic regions with co-located QTL there was not enough statistical evidence to strongly rule out pleiotropy as the cause of co-location. Differentiating close-linkage from pleiotropy was limited by allele frequencies, small QTL sizes and high linkage disequilibrium between QTL. Multiple-trait genomic prediction of Fusarium head blight severity of hybrid wheat is more accurate than single-trait prediction when the relatedness between estimation and prediction sets decreases. Different selection indices allow the simultaneous improvement of grain yield and protein content of rye (Secale cerale L.) for feeding purposes. These indices can be directly predicted by single-trait genomic prediction.

description: Professor Spivak challenges the traditional notions of "diaspora" and "transnational migration" in modern global society. Diaspora reflects a time when travel was not as easy as today. Transnational migration should be thought of beyond the idea of migration from one nation-state to another. In relation to the conference topic of Russian migration, she introduces the reality that what are thought of as "Russian" or Russian-speaking peoples actually represent a broad array of ethnic and language groups.

description: The terahertz transmission properties of symmetrical and asymmetrical annular apertures arrays (AAAs) are investigated both experimentally and numerically. It is found that only odd order resonant modes are observed for the symmetrical structures but both odd and even order resonances can be shown for the asymmetrical structures. Breaking the symmetry of AAAs by gradually displacing the H-shaped AAAs to U-shaped AAAs allows an intensity modulation depth of 99% of the second order resonance. Simulation results verify the experimental conclusions well. This result provides a tremendous opportunity for terahertz wavelength tunable filtering, sensing, and near-field imaging.

description: Perception of charisma, the ability to inﬂuence others by virtue of one’s personal qualities, appears to be inﬂuenced to some extent by cultural factors. We compare results of ﬁve studies of charisma speech in which American, Palestinian, and Swedish subjects rated Standard American English political speech and Americans and Palestinians rated Palestinian Arabic speech. We identify acoustic-prosodic and lexical features correlated with charisma ratings of both languages for native and non-native speakers and ﬁnd that 1) some acoustic-prosodic features correlated with charisma ratings appear similar across all ﬁve experiments; 2) other acoustic-prosodic and lexical features correlated with charisma appear speciﬁc to the language rated, whatever the native language of the rater; and 3) still other acoustic-prosodic cues appear speciﬁc to both rater native language and to language rated. We also ﬁnd that, while the absolute ratings non-native raters assign tend to be lower than those of native speakers, the ratings themselves are strongly correlated.

description: The many-body system comprising a He nucleus, three electrons, and a positron has been studied using the exact diagonalization technique. The purpose has been to clarify to which extent the system can be considered as a distinguishable positronium (Ps) atom interacting with a He atom and, thereby, to pave the way to a practical atomistic modeling of Ps states and annihilation in matter. The maximum value of the distance between the positron and the nucleus is constrained and the Ps atom at different distances from the nucleus is identified from the electron and positron densities, as well as from the electron-positron distance and center-of-mass distributions. The polarization of the Ps atom increases as its distance from the nucleus decreases. A depletion of the He electron density, particularly large at low density values, has been observed. The ortho-Ps pick-off annihilation rate calculated as the overlap of the positron and the free He electron densities has to be corrected for the observed depletion, specially at large pores/voids.

description: Mass spectrometry has been at the forefront of complex mixture analysis and, as a result, has greatly advanced the understanding of biological systems with its application in the biological sciences. One area in which mass spectrometry has succeeded is the area of microbiology and the identification of pathogens and has gained much attention from the biothreat detection community. Although this technology has matured in the past decade, very few systems have been developed for point-of-need analysis in cases such as the detection of biothreats. Current MS systems for the analysis of microbes utilizing MALDI-TOF-MS require large instruments to accommodate a drift tube long enough for high resolution mass analysis and high vacuum which is not amenable to the miniaturization requirements of point-of-need analysis. The previously mentioned methods also require extensive manipulation of the sample which takes time and can pose a risk to instrument operators in the biothreat detection space. Additionally, most mass spectrochemical instruments provide only one-dimension of data which can limits classification accuracy when using classification algorithms to provide an identity on a microbiological sample which could consist of any of the numerous common bacterial pathogens or biothreats.A possible solution to this problem is the implementation of two-dimensional tandem mass spectrometry (2D MS/MS) which allows the analysis of the product ions of all precursor ions representing the result in the 2D MS/MS data domain. This methodology is possible with a linear quadrupolar ion trap mass analyzer and can be applied to miniature ion trap technology for portability. In this dissertation, a progression of mass spectrochemical analysis of biological systems from conventional methods to the implementation of 2D MS/MS is demonstrated: by (i) the development of a rapid biomolecule extraction method to analyze bacterial spores, using a (ii) modified linear quadrupolar ion trap mass spectrometer, (iii) then a miniature ion trap mass spectrometer, and (iv) finally adding numerical methods to discriminate between biological systems using data acquired on each 2D MS/MS instrument. This work is then taken a step further by developing a high throughput experimentation method in which DESI is coupled to 2D MS/MS to analyze a moderate number of samples rapidly, automatically, and with high reproducibility.

description: ATP-dependent chromatin remodeling enzymes (CRE) are bio-molecular motors in eukaryotic cells. These are driven by a chemical fuel, namely, adenosine triphosphate (ATP). CREs actively participate in many cellular processes that require accessibility of specific segments of DNA which are packaged as chromatin. The basic unit of chromatin is a nucleosome where 146 bp $\sim$ 50 nm of a double stranded DNA (dsDNA) is wrapped around a spool formed by histone proteins. The helical path of histone-DNA contact on a nucleosome is also called "footprint". We investigate the mechanism of footprint traversal by a CRE that translocates along the dsDNA. Our two-state model of a CRE captures effectively two distinct chemical (or conformational) states in the mechano-chemical cycle of each ATP-dependent CRE. We calculate the mean time of traversal. Our predictions on the ATP-dependence of the mean traversal time can be tested by carrying out {\it in-vitro} experiments on mono-nucleosomes.

description: The response of the Cu(111) Shockley surface state to an external electrical field is characterized by combining a density-functional theory calculation for a slab geometry with an analysis of the Kohn-Sham wavefunctions. Our analysis is facilitated by a decoupling of the Kohn-Sham states via a rotation in Hilbert space. We find that the surface state displays isotropic dispersion, quadratic until the Fermi wave vector but with a significant quartic contribution beyond. We calculate the shift in energetic position and effective mass of the surface state for an electrical field perpendicular to the Cu(111) surface; the response is linear over a broad range of field strengths. We find that charge transfer occurs beyond the outermost copper atoms and that accumulation of electrons is responsible for a quarter of the screening of the electrical field. This allows us to provide well-converged determinations of the field-induced changes in the surface state for a moderate number of layers in the slab geometry.

Conformance Control for SAGD Using Oil-in-Water Emulsions in Heterogeneous Oil Sands Reservoirs
Creators: name: Ni, Yidan
Publisher: name: Schulich School of Engineering
Year: 2019
Subjects: subject: Engineering

description: Steam-Assisted Gravity Drainage (SAGD) is a widely used technology for heavy oil and bitumen recovery in Alberta, Canada. However, a SAGD conformance problem can arise due to the heterogeneity of oil sands reservoirs, such as the presence of high permeability zones and high water saturation zones. In particular, during a geomechanical dilation start-up process that has been developed and applied in SAGD start-up operations, the dilation fluid tends to flow into the high permeability zones, leaving the low permeability zones un-swept. Therefore, the high permeability zones must be temporarily and selectively blocked off so as to more effectively dilate the low permeability zones along a SAGD well-pair. Laboratory permeability reduction tests in sandpacks using oil-in-water (O/W) emulsion injection showed that a permeability reduction of up to 99.97% can be achieved. Results of emulsion injection in parallel-sandpack tests demonstrated that good conformance control can be obtained by a suitable combination of interfacial tension (IFT), emulsion quality, emulsion slug size, and oil phase viscosity of an emulsion system. The reservoir simulation study was conducted to first match the laboratory test results and then to optimize SAGD conformance control operations using emulsion injection in heterogeneous oil sands reservoirs. A field-scale SAGD simulation model was established to show that emulsion injection before the dilation start-up process can build up communication between the injector and producer, resulting in more uniform steam chamber growth, lower cumulative Steam-to-Oil ratio (cSOR), and higher cumulative oil production.

description: We examine a number of objective, automatically computable TURN-YIELDING CUES — distinct prosodic, acoustic and syntactic events in a speaker’s speech that tend to precede a smooth turn exchange —
in the Columbia Games Corpus, a large corpus of task-oriented dialogues. We show that the likelihood of occurrence of a turn-taking attempt from the interlocutor increases linearly with the number of cues conjointly displayed by the speaker. Our results are important for improving the coordination of speaking turns in interactive voice-response systems, so that systems can correctly estimate when the user is willing to yield the conversational ﬂoor, and so that they can produce their own turn-yielding cues appropriately.
Resilience in the Margins: Understanding resilience strategies of disempowered and marginalised senior leaders in the workplace.
Creators: name: Towey, Marsha
Publisher: name: University of Leicester
Year: 2023

description: Systemic Review This paper aims to critically evaluate the resilience strategies used by racialised leaders to enable them to overcome the barriers they face. A systematic search to identify qualitative studies was conducted across three electronic databases: PsychINFO, Business Source Premier and Web of Science. Thirteen studies met the inclusion criteria, from USA, Canada and UK and several industries. These were quality assessed and thematically synthesised. Three domains were identified as integral to understanding this area: (1) racialised micro-aggressions; (2) cost of fighting; and (3) resilience strategies used to overcome the micro-aggressions. Results suggest modern covert racism is evident within organisations. In the face of this, racialised leaders have developed individual and collective strategies to enable them to be resilient. Although some racialised individuals make it to leadership positions, this comes at a cost (health, psychological and emotional) to the individual. Organisations need to shift the burden of responsibility from the individual to address the prevailing Whiteness embedded within organisational systems.
 Empirical project The study sought to understand what resilience strategies senior female leaders in the clinical psychology profession use. Semi-structured interviews were conducted with 23 senior female clinical psychology leaders. Transcripts were analysed using reflexive thematic analysis. Three themes were generated: (1) Toxic Culture (2) Surviving within the system (3) Striving for change. The findings suggest that toxic work cultures are a challenge for senior female clinical psychologist leaders. They predominantly used individual resilience strategies to overcome these. However, these can come at an individual cost i.e. emotional burnout, low mood, stress and sleeping difficulties. Collective resilience strategies were used less often and were not focused on collectively changing the system. Collective resilience using critical consciousness model could enable lasting system and cultural change.

description: Challenges arise in testing applications that do not have test oracles, i.e., for which it is impossible or impractical to know what the correct output should be for general input. Metamorphic testing, introduced by Chen et al., has been shown to be a simple yet effective technique in testing these types of applications: test inputs are transformed in such a way that it is possible to predict the expected change to the output, and if the output resulting from this transformation is not as expected, then a fault must exist. Here, we improve upon previous work by presenting a new
technique called Metamorphic Runtime Checking, which automatically conducts metamorphic testing of both the entire application and individual functions during a program's execution. This new approach improves the scope, scale, and sensitivity of metamorphic testing by allowing for the identification of more properties and execution of more tests, and increasing the likelihood of detecting faults not be found by application-level properties alone. We also discuss a technique for automatically discovering functions' metamorphic properties, and present the results of new studies that demonstrate that Metamorphic Runtime Checking advances the state of the art in testing applications without oracles.
Adapting Kiribati, adapting projects : what happens when the World Bank does climate change adaptation?
Creators: name: Webber, Sophie
Publisher: name: University of British Columbia
Year: 2015

description: In this thesis I analyse the effects of the Kiribati Adaptation Project (KAP). The KAP is an early climate change adaptation project and it has been instrumental in the World Bank’s (the implementer of the KAP) expansion into the climate change agenda. I situate the KAP in the long, colonial, history of developmentalism and draw from critical development and policy studies to understand this project. Although climate change adaptation and development are contradictory in many senses, they have similarities: they are practiced by the same institutions, with the same project management techniques, and they are implemented through projects. I ask the following research questions: 1. What work does climate change adaptation do as an organising principle for a project? 2. How is climate change adaptation as a policy articulated into grounded practices? 3. What are the unintended effects of a novel climate change adaptation project in an archetypical vulnerable place? To answer these research questions I draw from six weeks field work in Kiribati, where I met with KAP project managers and consultants, government officials and other interested onlookers. In chapter three, I observe that the KAP was focused on producing technical reports and technical expertise. I analyse why this is the case and what some of the effects of this are. By participating in the KAP, consultants, funders and other i-Matang relatives of the project gain expertise in the novel, and increasingly lucrative, arena of climate change adaptation. In chapter four, I analyse the ways in which i-Kiribati actors assemble and perform their vulnerability to climate change. Performances are an intentional strategy to gain recognition for the plight of the low-lying and fragile atoll nation. Officials and public servants have little choice but to perform their vulnerability; the Government of Kiribati depends on these finances, but this dependence is uncertain. The KAP is a key site, as it exemplifies the asymmetries of climate change adaptation and mitigation. The KAP expects to create local resilience in the face of an exogenous threat, in the place least able to be resilient, and least responsible for causing the threat.

description: We have considered 53 Type Ia supernovae (SNe Ia) observed by the Swift X-Ray Telescope (XRT). None of the SNe Ia are individually detected at any time or in stacked images. Using these data and assuming that the SNe Ia are a homogeneous class of objects, we have calculated upper limits to the X- ray luminosity (0.2 - 10 keV) and mass-loss rate of L0.2-10 < 1.7\times1038 erg s-1 and M \cdot < 1.1\times10-6 M\odot yr-1 \times(vw)/(10 km s-1), respectively. The results exclude massive or evolved stars as the companion objects in SNe Ia progenitor systems, but allow the possibility of main sequence or small stars, along with double degenerate systems consisting of two white dwarfs, consistent with results obtained at other wavelengths (e.g., UV, radio) in other studies.

description: In this paper we consider a model for a nucleon interacting with the $ω$ and $σ$ mesons in the atomic nucleus. The model is relativistic, but we study it in the nuclear physics nonrelativistic limit, which is of a very different nature from the one of the atomic physics. Ground states with a given angular momentum are shown to exist for a large class of values for the coupling constants and the mesons' masses. Moreover, we show that, for a good choice of parameters, the very striking shapes of mesonic densities inside and outside the nucleus are well described by the solutions of our model.

description: The inseparability of career development and mental health is particularly evident within the context of post-secondary. Higher learners, specifically those at the undergraduate level, are widely recognized as a population that struggles with career uncertainty and unique mental health concerns. This manuscript delves into the reciprocal relationship between career development and mental health among post-secondary students and recent graduates of bachelor degree programs, exploring the impacts on both academic and personal wellbeing. Informed by the results of a recent study into the relationship between career preparation and student wellness, the author offers recommendations for students and service providers within the academic environment to better support both the career and mental wellbeing of higher learners.

description: Using a social justice framework, this arts-based engagement ethnography (ABEE) investigated the phenomenon of school integration among newcomer youth who migrated to Canada. Defined broadly, this phenomenon captures the adjustment of newcomer youth across all aspects of student life – both inside and outside the school context, including English Language Leaning (ELL), academic performance, classroom behaviour, social networking, emotional and familial well-being, involvement in school life, and understanding of the educational system. Specifically, two research questions were investigated: 1) How do newcomer youth experience school? and 2) How do these experiences influence their positive integration into the school system? Results from one participant – Anaya, a 19-year-old cisgender female who migrated to Canada from India with her family at the age of 12 – are presented to illustrate the manner in which the phenomenon of school integration can be used as a point of entry to study migration. These result included the following five themes: 1) The Struggle to Fit In / “I regard myself as a social outsider”, 2) Managing Parental Expectations / “Our values started to clash”, 3) Implications of Self-Exploration / “I was kind of in the middle”; 4) Finding a Passion and Getting Involved / “I became a lot more friendly”, and 4) Embracing a Multicultural Identity / “I am reembracing my heritage.”
2MASSJ035523.51+113337.4: A Young, Dusty, Nearby, Isolated Brown Dwarf Resembling A Giant Exoplanet

description: We present parallax and proper motion measurements, near-infrared spectra, and WISE photometry for the low surface gravity L5gamma dwarf 2MASSJ035523.37+113343.7 (2M0355). We use these data to evaluate photometric, spectral, and kinematic signatures of youth as 2M0355 is the reddest isolated L dwarf yet classified. We confirm its low-gravity spectral morphology and find a strong resemblance to the sharp triangular shaped $H$-band spectrum of the 10 Myr planetary-mass object 2M1207b. We find that 2M0355 is underluminous compared to a normal field L5 dwarf in the optical and MKO J,H, and K bands and transitions to being overluminous from 3-12 microns, indicating that enhanced photospheric dust shifts flux to longer wavelengths for young, low-gravity objects, creating a red spectral energy distribution. Investigating the near-infrared color magnitude diagram for brown dwarfs confirms that 2M0355 is redder and underluminous compared to the known brown dwarf population, similar to the peculiarities of directly imaged exoplanets 2M1207b and HR8799bcd. We calculate UVW space velocities and find that the motion of 2M0355 is consistent with young disk objects (< 2-3 Gyr) and it shows a high likelihood of membership in the AB Doradus association.

Toward a More Generous Space for Grief: Advocating for the Bereaved

description: The loss of a loved one is an immensely painful experience that leaves many clients, and their helping professionals, struggling to know how to respond to the depth of their suffering. In western society, death is frequently avoided among community members and professionals alike, and grief has become increasingly understood as a disorder to be diagnosed and treated rather than a profound existential reality that requires personal accompaniment. The aim of this paper is to provide a critique of these dominant attitudes towards death and grief and to outline an alternative, existential approach. Drawing upon the model of grief accompaniment proposed by Existential Analysis, we describe the ways in which we can make space for grief in ourselves and our relationships by turning-toward our loss. Such an approach is not only accepting of a wide variety of responses to loss, but also encourages more authentic emotional engagements with our own suffering and other bereaved persons. This attitude and approach to grief is illustrated through four recent qualitative studies, which explore how individuals, families, and communities made space for grieving in their lives. These research examples give rise to suggestions for how professionals and lay communities alike may advocate for the bereaved by participating in the shaping of more generous personal and social spaces for grief.

description: The present study explores the effectiveness of podcasts as an innovative tool for improving listening skills in English as a Foreign Language (EFL) learners. Given the increasing role of digital media in education, podcasts offer a flexible and engaging alternative to traditional listening exercises. This paper examines how podcasts contribute to EFL learners’ listening comprehension, motivation, and overall language acquisition. A mixed-methods approach was employed, combining pre-test and post-test assessments with surveys and interviews. The findings indicate that regular exposure to podcast-based learning materials significantly enhances learners’ ability to understand spoken English, particularly in terms of accent recognition, speech rate adaptation, and contextual comprehension. Furthermore, podcasts promote autonomous learning by allowing students to control their pace and choose topics based on their interests. The study concludes that incorporating podcasts into EFL curricula can effectively bridge the gap between classroom instruction and real-world language use.
Region of fidelities for a 1 -> N universal qubit quantum cloner

description: We analyze a region of fidelities for qubit which is obtained after an application of a 1 -> N universal quantum cloner. We express the allowed region for fidelities in terms of overlaps of pure states with irreps of S(n) (n = N+1) showing that the pure states can be taken with real coefficients only. Subsequently, the case n = 4, corresponding to a 1 -> 3 cloner is studied in more detail as an illustrative example. To obtain the main result, we make a convex hull of possible ranges of fidelities related to a given irrep. The formalism allows to construct the state giving rise to a given N-tuple of fidelities.

description: The internal 4-form field strengths with 7-dimensional indices have been constructed by de Wit and Nicolai in 1986. They are determined by the following six quantities: the 56-bein of 4-dimensional N=8 gauged supergravity, the Killing vectors on the round seven-sphere, the covariant derivative acting on these Killing vectors, the warp factor, the field strengths with 4-dimensional indices and the 7-dimensional metric. In this paper, by projecting out the remaining mixed 4-form field strengths in an SU(8) tensor that appears in the variation of spin 1/2 fermionic sector, we also write down them explicitly in terms of some of the above quantities. For the known critical points, the N=8 SO(8) point and the nonsupersymmetric SO(7)^{+} point, we reproduce the corresponding 11-dimensional uplifts by computing the full nonlinear expressions. Moreover, we find out the 11-dimensional lift of the nonsupersymmetric SO(7)^{+} invariant flow. We decode their implicit formula for the first time and the present work will provide how to obtain the new supersymmetric or nonsupersymmetric membrane flows in 11-dimensions.

description: We present four techniques for online handling of Out-of-Vocabulary words in Phrasebased Statistical Machine Translation. The techniques use spelling expansion, morphological expansion, dictionary term expansion and proper name transliteration to reuse or extend a phrase table. We compare the performance of these techniques and combine them. Our results show a consistent improvement over a state-of-the-art baseline in terms of BLEU and a manual error analysis.
