description: The objective of this paper is twofold: (i) to survey existing results of generalized polynomials on time scales, covering definitions and properties for both delta and nabla derivatives; (ii) to extend previous results by using the more general notion of diamond-alpha derivative on time scales. We introduce a new notion of combined-polynomial series on a time scale, as a convex linear combination of delta and nabla generalized series. Main results are formulated for homogenous time scales. As an example, we compute diamond-alpha derivatives on time scales for delta and nabla exponential functions.

description: Examination of thermal expansion of two-dimensional (2D) nanomaterials is a challenging theoretical task with either ab-initio or classical molecular dynamics simulations. In this regard, while ab-initio molecular dynamics (AIMD) simulations offer extremely accurate predictions, but they are excessively demanding from computational point of view. On the other side, classical molecular dynamics simulations can be conducted with affordable computational costs, but without predictive accuracy needed to study novel materials and compositions. Herein, we explore the thermal expansion of several carbon-based nanosheets on the basis of machine-learning interatomic potentials (MLIPs). We show that passively trained MLIPs over inexpensive AIMD trajectories enable the examination of thermal expansion of complex nanomembranes over wide range of temperatures. Passively fitted MLIPs could also with outstanding accuracy reproduce the phonon dispersion relations predicted by density functional theory calculations. Our results highlight that the devised methodology on the basis of passively trained MLIPs is computationally efficient and versatile to accurately examine the thermal expansion of complex and novel materials and compositions using the molecular dynamics simulations.

description: It is of interest to study supergravity solutions preserving a non-minimal fraction of supersymmetries. A necessary condition for supersymmetry to be preserved is that the spacetime admits a Killing spinor and hence a null or timelike Killing vector field. Any spacetime admitting a covariantly constant null vector field ($CCNV$) belongs to the Kundt class of metrics, and more importantly admits a null Killing vector field. We investigate the existence of additional non-spacelike isometries in the class of higher-dimensional $CCNV$ Kundt metrics in order to produce potential solutions that preserve some supersymmetries.

description: In this work we study the properties of the mass density field in the non-Gaussian world models simulated by Grossi et al. 2007. In particular we focus on the one-point density probability distribution function of the mass density field in non-Gausian models with quadratic non-linearities quantified by the usual parameter f_NL. We find that the imprints of primordial non-Gaussianity are well preserved in the negative tail of the probability function during the evolution of the density perturbation. The effect is already noticeable at redshifts as large as 4 and can be detected out to the present epoch. At z=0 we find that the fraction of the volume occupied by regions with underdensity delta < -0.9, typical of voids, is about 1.3 per cent in the Gaussian case and increases to ~2.2 per cent if f_NL=-1000 while decreases to ~0.5 per cent if f_NL=+1000. This result suggests that void-based statistics may provide a powerful method to detect non-Gaussianity even at low redshifts which is complementary to the measurements of the higher-order moments of the probability distribution function like the skewness or the kurtosis for which deviations from the Gaussian case are detected at the 25-50 per cent level.

description: While it is well known which curricular practices can improve student performance on measures of conceptual understanding, the sustaining of these practices and the role of faculty members in implementing these practices are less well understood. We present a study of the hand-off of Tutorials in Introductory Physics from initial adopters to other instructors at the University of Colorado, including traditional faculty not involved in physics education research. The study examines the impact of implementation of Tutorials on student conceptual learning across eight first-semester, and seven second-semester courses, for fifteen faculty over twelve semesters, and includes roughly 4000 students. It is possible to demonstrate consistently high, and statistically indistinguishable, student learning gains for different faculty members; however, such results are not the norm, and appear to rely on a variety of factors. Student performance varies by faculty background - faculty involved in, or informed by physics education research, consistently post higher student learning gains than less-informed faculty. Student performance in these courses also varies by curricula used - all semesters in which the research-based Tutorials and Learning Assistants are used have higher student learning gains than those semesters that rely on non-research based materials and do not employ Learning Assistants.

The radiative transfer at second order: a full treatment of the Boltzmann equation with polarization

Year: 2008
Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)
subject: Astrophysics (astro-ph)

description: This article investigates the full Boltzmann equation up to second order in the cosmological perturbations. Describing the distribution of polarized radiation by a tensor valued distribution function, we study the gauge dependence of the distribution function and summarize the construction of the gauge-invariant distribution function. The Liouville operator which describes the free streaming of electrons, and the collision term which describes the scattering of photons on free electrons are computed up to second order. Finally, the remaining dependence in the direction of the photon momentum is handled by expanding in projected symmetric trace-free multipoles and also in the more commonly used normal modes components. The results obtained remain to be used for computing numerically the contribution in the cosmic microwave background bispectrum which arises from the evolution of second order perturbations, in order to disentangle the primordial non-Gaussianity from the one generated by the subsequent non-linear evolution.

Residential milieu and locational suitability : a study of selected elderly residents in non-profit care facilities within Greater Vancouver
Creators: name: Fallick, Arthur Laurence
Publisher: name: University of British Columbia
Year: 2010

description: As the age structure of Canadian society changes in the ensuing decades, housing and caring for the elderly will undoubtedly take on increased significance, and consequently, it is crucial that our social institutions begin to prepare now for this change. This thesis focuses upon the opinions of a selected number of residents of fifteen Personal and Intermediate Care Facilities operated by non-profit organisations within the Greater Vancouver Regional District, which are now an integral part of the recently inaugurated Long Term Care Program in British Columbia. An initial fundamental premise of the research was that a poor location, one which serves to physically isolate residents and reduce their interaction with the wider coimiunity, would likely engender social isolation with a concomittant reduction in individual well-being. While geographers and others have developed location - allocation algorithms for determining the optimal location of e.g. health facilities, a notable deficiency of such analytical methods is their lack of attention to the needs and opinions of those whom the facilities are designed to serve. In an attempt to rectify this situation a survey of fifteen per cent of the residents in each of the selected institutions was conducted to improve our understanding of how well the facilities were serving the occupants, and in particular, whether or not they are well situated with respect to the locational preferences of the elderly. It has been argued that the space - occupancy behaviour of the elderly is extremely sensitive to their surroundings and that the location of structures and spaces assumes greater significance especially when the constraints on mobility are taken into account. These and associated questions are addressed through the analysis of the responses to the questionnaire which was administered. In evaluating a person's degree of residential satisfaction, it is unrealistic to separate the dwelling unit from its surroundings or its locality. Both are an integral part of what has here been termed "residential milieu" which includes both the institutional milieu and those parts of the surrounding area which the individual uses to satisfy his or her physical and psycho-social needs. The results generally confirm the notion that life satisfaction is positively related to the level of residential satisfaction and mobility. While the respondents' assessment of the surrounding area is less centrally related to their sense of well-being we are reluctant to conclude that the location of a care facility is unimportant.

Tidal Disruption of Protoclusters in Giant Molecular Clouds

Publisher: name: arXiv
Year: 2008
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: We study the collapse of protoclusters within a giant molecular cloud (GMC) to determine the conditions under which collapse is significantly disrupted. Motivated by observations of star forming regions which exhibit flattened cloud structures, this study considers collapsing protoclusters with disk geometries. The collapse of a 10^3 Msun protocluster initially a distance of 2-10 pc from a 10^3 - 10^6 Msun point mass is numerically calculated. Simulations with zero initial relative velocity between the two are completed as well as simulations with relative velocities consistent with those observed in GMCs. The results allow us to define the conditions under which it is safe to assume protocluster collapse proceeds as if in isolation. For instance, we find the collapse of a 10^3 Msun protocluster will be significantly disrupted if it is within 2-4 pc of a 10^4 Msun point mass. Thus, the collapse of a 10^3 Msun protocluster can be considered to proceed as if in isolation if it is more than ~ 4 pc away from a 10^4 Msun compact object. In addition, in no portion of the sampled parameter space does the gravitational interaction between the protocluster disk and the massive particle significantly disperse the disk into the background GMC. We discuss the distribution of clusters of young stellar objects within the Perseus and Mon R2 star forming regions, which are consistent with the results of our simulations and the limitations of our results in gas dominated regions such as the Orion cloud.

MAIN RISK FACTORS CONTRIBUTING TO CARDIOVASCULAR DISEASES: GENETIC, ENVIRONMENTAL, LIFESTYLE, AND THEIR IMPACT ON DISEASE DEVELOPMENT
Creators: name: Yo'ldosheva, S.G.

Publisher: name: Zenodo

description: Cardiovascular diseases (CVD) are a leading cause of morbidity and mortality worldwide, placing significant pressure on global health systems. This paper explores the primary risk factors contributing to the development of CVD, focusing on genetic, environmental, and lifestyle factors. It highlights the complex interaction between these factors and their role in the pathogenesis and progression of cardiovascular diseases. Genetic predisposition, environmental pollution, and unhealthy lifestyle choices, such as poor diet, smoking, and physical inactivity, all play critical roles in the onset and progression of these diseases. By understanding these factors and their interplay, more effective prevention strategies and treatment options can be developed to combat the global burden of CVD.
A Global Monitoring Practice in the Making
Creators: name: Biermann, Julia
name: Pfahl, Lisa
Publisher: name: Austrian Journal of Historical Studies
Year: 2021

description: In this paper, we examine a global assessment practice in the making: the measurement procedures proposed by the international community to monitor the Sustainable Development Goals (SDGs). Our focus is on SDG 4, which requires UN member states to ensure inclusive education systems in order to realise the right to education for all, including persons with disabilities. To identify persons with disabilities, a global disability measure was introduced: the Washington Group Questions (WGQ). In line with the human rights norm of inclusion, the WGQ aim to reflect a social model of disability. We explore this claim based on a Sociology of Knowledge Approach to Discourse combined with insights from Disability Studies. To this end, we show first, how a social model approach to disability was developed by the international community regarding the human right to education, and, secondly, how this approach is supposed to be applied in disability measurements for the monitoring of SDG 4. Based on our analysis, we will argue that the WGQ do not fully capture a social model of disability yet; instead, they introduce a social model of impairment. Even though these measurements increase the visibility of persons with disabilities in the monitoring of SDG 4, they do not yet allow to comprehensively identify the barriers disabled persons face in realising their right to education.

Mansa Koli Bojang,the Last King of Kombo and his British Ally: Loyalty meets Neutrality

Publisher: name: Stichproben. Vienna Journal of African Studies
Year: 2020

description: This article reconstructs the pre-colonial intercultural encounter between the warrior-class of the Soninké and the first British settlement in West Africa situated at the mouth of the River Gambia. By framing the vast topic with the diplomatic endeavour of king Koli Bojang to win the British as an ally in his war against the Muslims and with the response of the administration of thesettlement to it in the first half of the 1870s, I will show in reference to the letter-correspondence between the king and the administrators, and by analysing the colonial records and oral traditions that honour based loyalty clashed with biased neutrality. In detail, the Soninké were loyal to their British neighbours, because they considered them as friends in the Manding-meaning of the term; the British on the other hand were disloyal to their long time partners, due to their foreign policy of neutrality, even though the reality proves that the officers on the spot were partial, at their own discretion, being driven by sympathies and ideologies. This biased neutrality though contradicted the warrior ethics of the Soninké, resulting in their rejection of the British offer to mediate, since a mediator, through their prism, had to embody high moral values, e.g. honesty and truthfulness.

description: In a recent Letter [PRL 96, 226802 (2006)], Dalpian and Chelikowsky claimed that formation energies of Mn impurities in CdSe nanocrystals increase as the size of the nanocrystal decreases, and argued that this size dependence leads to "self-purification" of small nanocrystals. They presented density-functional-theory (DFT) calculations showing a strong size dependence for Mn impurity formation energies, and proposed a general explanation. In this Comment we show that several different DFT codes, pseudopotentials, and exchange-correlation functionals give a markedly different result: We find no such size dependence. More generally, we argue that formation energies are not relevant to substitutional doping in most colloidally grown nanocrystals.

description: A flag complex can be defined as a simplicial complex whose simplices correspond to complete subgraphs of its 1-skeleton taken as a graph. In this article, by introducing the notion of s-dismantlability, we shall define the s-homotopy type of a graph and show in particular that two finite graphs have the same s-homotopy type if, and only if, the two flag complexes determined by these graphs have the same simplicial simple-homotopy type (Theorem 2.10, part 1). This result is closely related to similar results established by Barmak and Minian (Adv. in Math., 218 (2008), 87-104) in the framework of posets and we give the relation between the two approaches (theorems 3.5 and 3.7). We conclude with a question about the relation between the s-homotopy and the graph homotopy defined by Chen, Yau and Yeh (Discrete Math., 241(2001), 153-170).

description: We study the effect of torsional deformations on the electronic properties of single-walled transition metal dichalcogenide (TMD) nanotubes. In particular, considering forty-five select armchair and zigzag TMD nanotubes, we perform symmetry-adapted Kohn-Sham density functional theory calculations to determine the variation in bandgap and effective mass of charge carriers with twist. We find that metallic nanotubes remain so even after deformation, whereas semiconducting nanotubes experience a decrease in bandgap with twist -- originally direct bandgaps become indirect -- resulting in semiconductor to metal transitions. In addition, the effective mass of holes and electrons continuously decrease and increase with twist, respectively, resulting in n-type to p-type semiconductor transitions. We find that this behavior is likely due to rehybridization of orbitals in the metal and chalcogen atoms, rather than charge transfer between them. Overall, torsional deformations represent a powerful avenue to engineer the electronic properties of semiconducting TMD nanotubes, with applications to devices like sensors and semiconductor switches.

To constrain dust properties in this region, we have performed radio observations toward this disk using the Karl G. Jansky Very Large Array (JVLA) in 2020 June-July, September, and November. We also performed complementary optical photometric monitoring observations. We found that the dust thermal emission from the hot inner disk mid-plane of FU Ori has been approximately stationary and the maximum dust grain size is $\gtrsim$1.6 mm in this region. If the hot inner disk of FU Ori which is inward of the 150-170 K water snowline is turbulent (e.g., corresponding to a Sunyaev & Shakura viscous $α_{t}\gtrsim$0.1), or if the actual maximum grain size is still larger than the lower limit we presently constrain, then as suggested by the recent analytical calculations and the laboratory measurements, water-ice free dust grains may be stickier than water-ice coated dust grains in protoplanetary disks. Additionally, we find that the free-free emission and the Johnson B and V bands magnitudes of these binary stars are brightening in 2016-2020. The optical and radio variability might be related to the dynamically evolving protostellar or disk accretion activities. Our results highlight that hot inner disks of outbursting objects are important laboratories for testing models of dust grain growth. Given the active nature of such systems, to robustly diagnose the maximum dust grain sizes, it is important to carry out coordinated multi-wavelength radio observations.

description: Understanding the interplay among different magnetic exchange interactions and its physical consequences, especially in the presence of itinerant electrons and disorders, remains one of the central themes in condensed matter physics. In this vein, the coupling between antiferromagnetic and spin glass orders may lead to large exchange bias, a property of potential broad technological applications. In this article, we report the coexistence of antiferromagnetic order and spin glass behaviors in a quasi-one-dimensional iron telluride TaFe$_{1+x}$Te$_3$ ($x$=0.25). Its antiferromagnetism is believed to arise from the antiferromagnetic interchain coupling between the ferromagnetically aligned FeTe chains along the $b$-axis, while the spin glassy state stems from the disordered Fe interstitials. This dichotomic role of chain and interstitial sublattices is responsible for the large exchange bias observed at low temperatures, with the interstitial Fe acting as the uncompensated moment and its neighboring Fe chain providing the source for its pinning. This iron-based telluride may thereby represent a new paradigm to study the large family of transition metal chalcogenides whose magnetic order or even the dimensionality can be tuned to a large extent, forming a fertile playground to manipulate or switch the spin degrees of freedom thereof.
Identification of the Origin of Monojet Signatures at the LHC

description: Several new physics scenarios can lead to monojet signatures at the LHC. If such events are observed above the Standard Model background it will be important to identify their origin. In this paper we compare and contrast these signatures as produced in two very different pictures: vector or scalar unparticle production in the scale-invariant/conformal regime and graviton emission in the Arkani-Hamed, Dimopoulos and Dvali extra-dimensional model. We demonstrate that these two scenarios can be distinguished at the LHC for a reasonable range of model parameters through the shape of their respective monojet and/or missing $E_T$ distributions.

Cytogenetic analysis of single hemopoietic colonies
Creators: name: Dubé, Ian David
Publisher: name: University of British Columbia

description: Cytogenetic analysis of fresh marrow provides an assessment primarily of the distribution of karyotypes in the most differentiated compartments of proliferating hemopoietic cells. In theory, it should be possible to obtain similar information for more primitive cell types since, under appropriate conditions in vitro, these are stimulated to form colonies of identifiable progeny. Although the importance of such an approach, particularly in studies of the hemopoietic malignancies, has been recognized for a number of years, colonies of more than 1,000 cells are rarely obtained, and severe technical problems have hampered the acquisition of reliable data. In this work, a microtechnique has been developed which enables high quality chromosomes (suitable for G- or Q-banding) to be obtained from single erythroid colonies grown from human blood or bone marrow in standard methylcellulose cultures. Thus, it is now possible to begin an analysis of chromosomal changes in the progeny of individual erythroid stem cells. This provides a new approach to the cytogenetic study of the origin and progression of the human myeloproliferative diseases.

description: Squeezed correlations of particle-antiparticle pairs, also called Back-to-Back Correlations, are predicted to appear if the hadron masses are modified in the hot and dense hadronic medium formed in high energy nucleus-nucleus collisions. Although well-established theoretically, the squeezed-particle correlations have not yet been searched for experimentally in high energy hadronic or heavy ion collisions, clearly requiring optimized forms to experimentally search for this effect. Within a non-relativistic treatment developed earlier we show that one promising way to search for the BBC signal is to look into the squeezed correlation function of pairs of phi-mesons at RHIC energies, plotted in terms of the average momentum of the pair, K12=(k1+k2)/2. This variable's modulus, 2|K12|, is the non-relativistic limit of the variable Q_bbc, introduced herewith. The squeezing effects on the HBT correlation function are also discussed.

Publisher: name: Young Information Scientist
Year: 2021

description: Objective: Detailed needs-assessments of the target groups are of particular relevance when developing new services for eScience. This study aims to identify the demands of researchers in natural sciences regarding metadata for research data. Methods: This paper applies the key points of Grounded Theory to analyze eight semi-structured interviews with scientists from the University of Vienna and the Medical University of Vienna. The interviews were conducted from April to May 2019 as part of the project e-Infrastructures Austria Plus funded by the Austrian Federal Ministry of Education, Science and Research. Results: The results illustrate how scientists understand the term “metadata”. The study identifies several examples of describing data as well as six areas of researchers' requirements for data management services. These include the need to design efficient solutions in German and English, the demand for technical infrastructure and dedicated data stewards who bring expertise from a relevant discipline. Service providers further need to take interdisciplinary differences into account when developing new forms of training and support. Conclusion: While the researchers’ statements highlight the various ways they describe data, the interviews also indicate a lack of understanding of the term “metadata”. Together with the six areas of needs and requirements, these demonstrate the need for action by libraries and other service providers in order to further contribute to the development of sustainable research data management.

description: Understanding product attributes plays an important role in improving online shopping experience for customers and serves as an integral part for constructing a product knowledge graph. Most existing methods focus on attribute extraction from text description or utilize visual information from product images such as shape and color. Compared to the inputs considered in prior works, a product image in fact contains more information, represented by a rich mixture of words and visual clues with a layout carefully designed to impress customers. This work proposes a more inclusive framework that fully utilizes these different modalities for attribute extraction. Inspired by recent works in visual question answering, we use a transformer based sequence to sequence model to fuse representations of product text, Optical Character Recognition (OCR) tokens and visual objects detected in the product image. The framework is further extended with the capability to extract attribute value across multiple product categories with a single model, by training the decoder to predict both product category and attribute value and conditioning its output on product category. The model provides a unified attribute extraction solution desirable at an e-commerce platform that offers numerous product categories with a diverse body of product attributes. We evaluated the model on two product attributes, one with many possible values and one with a small set of possible values, over 14 product categories and found the model could achieve 15% gain on the Recall and 10% gain on the F1 score compared to existing methods using text-only features.

description: We analytically calculate the low-lying gravitational quasinormal modes of a topological AdS black hole of arbitrary dimension. We show that they are in agreement with corresponding results from the hydrodynamics of the gauge theory plasma on the boundary, as required by the AdS/CFT correspondence. For some of these modes, we obtain a lifetime which is comparable to or longer than the longest lifetime of perturbations of spherical black holes. Thus, these modes are expected to play an important role in the late time behavior of the gauge theory plasma.
