description: В статье исследуется выполнение теоремы вириала 1:2:3:4 для теории полярона Гросса-Тулуба. Показано, что в минимуме поляронного функционала теорема вириала выполняется не для всех пробных функций. Введение дополнительного параметра приводит не только к понижению энергии полярона, но и к выполнению теоремы вириала. Вариационные расчёты проведены для точного поляронного функционала, полученного в рамках метода Гросса-Тулуба в области промежуточной и сильной связи (до a = 25), для которой выполняется терема 1:3:4. Соотношение 1:2 не выполняется даже приближенно, что свидетельствует о том, что зависимость энергии полярона от a не является квадратичной для данной области параметров.
Integrating protocol modelling into reusable aspect models
Creators: name: Ayed, Abir

description: Aspect-oriented modelling approaches, e.g. the multi-view modelling approach Reusable Aspect Models (RAM), advocate to model concerns separately, and then to use model composition to create complex models in which these concerns are intertwined. In such a context, specifying the composition of the models is a non-trivial task, in particular when it comes to specifying the composition of behavioural models. This is the case for RAM message views, which define behaviour using sequence diagrams. In this paper we describe how we added an additional behavioural view to RAM -- the state view -- that specifies the allowed invocation protocol of class instances.. We discuss why Protocol Modelling, a compositional modelling approach based on state diagrams, is an ideal notation to specify such a state view, and show how we added support for protocol modelling to the RAM metamodel. Finally, we demonstrate how to model using the new state views by means of an example, and explain how state views can be exploited to verify the correctness of compositions.

description: Players of digital games are limited by the constraints of the game's implementation. Players cannot fly a kite, plant a tree or make friends with a dragon if these activities were not coded within the game. Game orchestration relaxes these restrictions by allowing players to create game narratives and settings as the game is being played. This enables players to express their creativity beyond the strictures of the game's implementation. We present Tabula Rasa, a novel game orchestration tool based on an efficient tabletop interface. Based on a study of 20 game orchestration sessions using Tabula Rasa, we identify five behavioural patterns adopted by orchestrators, and four styles of collaborative interaction between orchestrators and players. Finally, we present recommendations for designers of game orchestration systems.

description: Relative spatial consistency - that is, the stable arrangement of objects in a 2D presentation - provides several benefits for interactive interfaces. Spatial consistency allows users to develop memory of object locations, reducing the time needed for visual search, and because spatial memory is long lasting and has a large capacity these performance benefits are enduring and scalable. This suggests that spatial consistency could be used as a fundamental principle for the design of interfaces. However, there are many display situations where the standard presentation is altered in some way: e.g., a window is moved to a new location, scaled, or rotated on a mobile or tabletop display. It is not known whether the benefits of spatial organization are robust to these common kinds of view transformation. To assess these effects, we tested user performance with a spatial interface that had been transformed in several ways, including different degrees of translation, rotation, scaling, and perspective change. We found that performance was not strongly affected by the changes, except in the case of large rotations. To demonstrate the value of spatial consistency over existing mechanisms for dealing with view changes, we compared user performance with a spatially-stable presentation (using scaling) with that of a 'reflowing' presentation (widely used in current interfaces). This study showed that spatial stability with scaling dramatically outperforms reflowing. This research provides new evidence of spatial consistency's value in interface design: it is robust to the view transformations that occur in typical environments, and it provides substantial performance advantages over traditional methods.

description: In the past few years more and more pieces of evidence have been presented for a revision of the widely accepted Unified Model of Active Galactic Nuclei. A model based solely on orientation cannot explain all the observed phenomenology. In the following, we will present evidence that accretion rate is also a key parameter for the presence of Hidden Broad Line Regions in Seyfert 2 galaxies. Our sample consists of 21 sources with polarized Hidden Broad Lines and 18 sources without Hidden Broad Lines. We use stellar velocity dispersions from several studies on the CaII and Mg b triplets in Seyfert 2 galaxies, to estimate the mass of the central black holes via the Mbh-σ\ast relation. The ratio between the bolometric luminosity, derived from the intrinsic (i.e. unabsorbed) X-ray luminosity, and the Eddington luminosity is a measure of the rate at which matter accretes onto the central supermassive black hole. A separation between Compton-thin HBLR and non-HBLR sources is clear, both in accretion rate (log Lbol/LEdd = -1.9) and in luminosity (log Lbol = 43.90). When, properly luminosity-corrected, Compton-thick sources are included, the separation between HBLR and non-HBLR is less sharp but no HBLR source falls below the Eddington ratio threshold. We speculate that non-HBLR Compton-thick sources with accretion rate higher than the threshold, do possess a BLR, but something, probably related to their heavy absorption, is preventing us from observing it even in polarized light. Our results for Compton-thin sources support theoretical expectations. In a model presented by Nicastro (2000), the presence of broad emission lines is intrinsically connected with disk instabilities occuring in proximity of a transition radius, which is a function of the accretion rate, becoming smaller than the innermost stable orbit for very low accretion rates and therefore luminosities.

description: Data operations and command centers are crucial for managing today's Internet-based economy. Despite advances in automation, the challenges placed on operations professionals continue to increase as they work individually or in teams to repair or proactively avoid service disruptions. Although there have been a few studies of collaborative work in military supervisory control centers, due to the sensitive nature of work in operating centers, there have been few studies on the activities that take place in commercial data centers. In this case study of a large, complex data operations and control center, activity theory is used to guide and interpret observations of individual and collaborative work. This resulted in a model of data operations activities, and the identification of tensions that arise within and between these activities. This model is of value to interaction engineers in the first phase of a user-centered engineering methodology. Using this model, we provide some recommendations for reducing some of the tensions we found, and discuss significant opportunities and challenges in this new domain for the HCI community.

description: In-plane temperature dependent dielectric behavior of BiFeO3 (BFO) as-grown thin films show diffuse but prominent phase transitions near 450 (+/-10) K and 550 K with dielectric loss temperature dependences that suggest skin layer effects. The 450 K anomalies are near the "transition" first reported by Polomska et al. [Phys. Stat. Sol. 23, 567 (1974)]. The 550 K anomalies coincide with the surface phase transition recently reported [Xavi et al. PRL 106, 236101 (2011)]. In addition, anomalies are found at low temperatures: After several experimental cycles the dielectric loss shows a clear relaxor-like phase transition near what was previously suggested to be a spin reorientation transition (SRT) temperature (~ 201 K) for frequencies 1 kHz < f < 1MHz which follow a nonlinear Vogel-Fulcher (V-F) relation; an additional sharp anomaly is observed near ~180 K at frequencies below 1 kHz. As emphasized recently by Cowley et al. [Adv. Phys. 60, 229 (2011)], skin effects are expected for all relaxor ferroelectrics. Using the interdigital electrodes, experimental data and a theoretical model for in-plane longitudinal and transverse direct magnetoelectric (ME) coefficient are presented.

description: We present a simple model for the non-thermal emission from the historical supernova remnant SN 1006. We constrain the synchrotron parameters of the model with archival radio and hard X-ray data. Our stationary emission model includes two populations of electrons, which is justified by multi-frequency images of the object. From the set of parameters that predict the correct synchrotron flux we select those which are able to account, either partly or entirely, for the gamma-ray emission of the source as seen by HESS. We use the results from this model as well as the latest constraints imposed by the Fermi observatory and conclude that the TeV emission cannot be accounted for by neutral pion decay produced by high-energy cosmic rays with a single "soft" power-law distribution (i.e., with a particle index greater than 2 or so).

description: People often use mobile devices to access information during conversations in casual settings, but mobile devices are not well suited for interaction in groups. Large situated displays promise to better support access to and sharing of information in casual conversations. This paper presents the LunchTable, a multi-user system based on semi-public displays that supports such casual group interactions around a lunch table. We describe our design goals and the resulting system, as well as a weeklong study of the interaction with the system in the lunch space of a research lab. Our results show substantial use of the LunchTable for sharing visual information such as online maps and videos that are otherwise difficult to share in conversations. Also, equal simultaneous access from several users does not seem critical in casual group interactions.
The role of pannexins, a novel gap junction family, in glioma oncogenicity and neuronal differentiation
Creators: name: Lai, Pin-Kuang Charles
Publisher: name: University of British Columbia
Year: 2010

description: Gap junctions are unique intercellular channels assembled from the canonical gap junction family, connexins (Cxs). These channels connect the cytosols of adjacent cells, allowing direct passages of small ions and molecules for intercellular communication and homeostasis within tissues. A novel family of gap junction proteins, pannexins (Panxs), with low sequence similarity to the invertebrate gap junctions, innexins, was recently discovered in chordates. Similar to Cxs, Panxs are also capable of forming functional hemichannels as well as intercellular channels. Aberrations in gap junctions have been associated with abnormal CNS development and diseases including gliomas. The main purpose of this thesis was to determine if Panxs play a functional role under pathological and normal CNS conditions, each of which is represented by gliomas and neuronal differentiation, respectively. A loss of Panx expression was found in the C6 glioma cell line when compared to its normal counterparts, primary astrocytes. Restoring Panx1 and Panx2 expression in C6 glioma cells by stable transfection induced a dramatically flattened morphology, which is similar to the flat and polygonal shape of cultured astrocytes. Both Panx1 and Panx2 also significantly suppressed the neoplastic phenotype of C6 glioma cells, including in vitro monolayer growth, anchorage-independent growth, and in vivo tumorigenesis in immunodeficient mice. Interestingly, while Panx1 reduced cell motility in C6 glioma cells, Panx2 did not elicit a similar effect. Panx1 and Panx2 exhibited a distinct subcellular localization. Panx1 was detected at the plasma membrane and perinuclear regions, whereas Panx2 was only found in membrane-bound compartments within the cytosol, hence suggesting mechanistically different tumor-suppressive pathways employed by the two Panxs. Furthermore, it was determined that Panx1 and Panx3, but not Panx2, increased neurite numbers and further enhanced neurite outgrowth in PC12 cells during nerve growth factor-induced neuronal differentiation. In conclusion, findings from this thesis suggest a functional role of Panxs in normal and pathological conditions of the CNS, and merit critical future investigations to explore their underlying mechanisms and therapeutic implication in diseases.
Fano resonances and electron spin transport through a two-dimensional spin-orbit-coupled quantum ring

description: Electron transport through a spin-orbit-coupled quantum ring is investigated within linear response theory. We show that the finite width of the ring results in the appearance of Fano resonances in the conductance. This turns out to be a consequence of the spin-orbit interaction that leads to a breaking of the parity of the states localized in the ring. The resonances appear when the system is close to maxima of Aharonov-Casher conductance oscillations where spin transfer is heavily modified. When the spin-orbit coupling strength is detuned from the Aharonov-Casher maxima the resonances are broadened resulting in a dependence of the spin transport on the electron Fermi energy in contrast to predictions from one-dimensional models

description: Agile project planning plays an important part in agile software development. In distributed settings, project planning is severely impacted by the lack of face-to-face communication and the inability to share paper index cards amongst all meeting participants. To address these issues, several distributed agile planning tools were developed. The tools vary in features, functions and running platforms. In this chapter, we first summarize the requirements for distributed agile planning. Then we give an overview on existing agile planning tools. We also evaluate existing tools based on tool requirements. Finally, we present some practical advices for both designers and users of distributed agile planning tools.
Understanding performance in touch selections: Tap, drag and radial pointing drag with finger, stylus and mouse
Creators: name: Cockburn, A.

Publisher: name: Elsevier
Year: 2012

description: Touch-based interaction with computing devices is becoming more and more common. In order to design for this setting, it is critical to understand the basic human factors of touch interactions such as tapping and dragging; however, there is relatively little empirical research in this area, particularly for touch-based dragging. To provide foundational knowledge in this area, and to help designers understand the human factors of touch-based interactions, we conducted an experiment using three input devices (the finger, a stylus, and a mouse as a performance baseline) and three different pointing activities. The pointing activities were bidirectional tapping, one-dimensional dragging, and radial dragging (pointing to items arranged in a circle around the cursor). Tapping activities represent the elemental target selection method and are analysed as a performance baseline. Dragging is also a basic interaction method and understanding its performance is important for touch-based interfaces because it involves relatively high contact friction. Radial dragging is also important for touch-based systems as this technique is claimed to be well suited to direct input yet radial selections normally involve the relatively unstudied dragging action, and there have been few studies of the interaction mechanics of radial dragging. Performance models of tap, drag, and radial dragging are analysed. For tapping tasks, we confirm prior results showing finger pointing to be faster than the stylus/mouse but inaccurate, particularly with small targets. In dragging tasks, we also confirm that finger input is slower than the mouse and stylus, probably due to the relatively high surface friction. Dragging errors were low in all conditions. As expected, performance conformed to Fitts' Law. Our results for radial dragging are new, showing that errors, task time and movement distance are all linearly correlated with number of items available. We demonstrate that this performance is modelled by the Steering Law (where the tunnel width increases with movement distance) rather than Fitts' Law. Other radial dragging results showed that the stylus is fastest, followed by the mouse and finger, but that the stylus has the highest error rate of the three devices. Finger selections in the North-West direction were particularly slow and error prone, possibly due to a tendency for the finger to stick–slip when dragging in that direction.

Adaptive forward error correction for real-time groupware

Publisher: name: ACM
Year: 2012

description: Real-time distributed groupware sends several kinds of messages with varying quality-of-service requirements. However, standard network protocols do not provide the flexibility needed to support these different requirements (either providing too much reliability or too little), leading to poor performance on real-world networks. To address this problem, we investigated the use of an application-level networking technique called adaptive forward error correction (AFEC) for real-time groupware. AFEC can maintain a predefined level of reliability while avoiding the overhead of packet acknowledgement or retransmission. We analysed the requirements of typical real-time groupware systems and developed an AFEC technique to meet these needs. We tested the new technique in an experiment that measured message reliability and latency using TCP, plain UDP, UDP with non-adaptive FEC, and UDP with our AFEC scheme, under several simulated network conditions. Our results show that for awareness messages that can tolerate some loss, FEC approaches keep latency at nearly the plain-UDP level while dramatically improving reliability. In addition, adaptive FEC is the only technique that can maintain a specified level of reliability and also minimize delay as network conditions change. Our study shows that groupware AFEC can be a useful tool for improving the real-world performance and usability of real-time groupware.

description: We aimed to systematically review and synthesise the impact of rehabilitation with games in people after knee arthroplasty. We conducted a systematic review following the Preferred Reporting Items for the declaration of Systematic Reviews (PRISMA – Preferred Reporting Items for Systematic Reviews and Meta-Analysis). The summary of evidence was developed using the Grading of Recommendations, Assessment, Development, and Assessment (GRADE). The review included randomised controlled trials that used characteristics of games in rehabilitation. Eight articles from a total of 1289 identified articles were included after duplicates were removed. In total, 239 participants participated. There were no statistically significant changes between the groups using the exergames and control groups. The level of evidence was rated using GRADE and was very low or moderate. The difference in grouped means was not significant for Knee Flexion, Knee extension, Range of Motion, WOMAC (Western Ontario and McMaster Universities Arthritis Index), AKSS (American Knee Society Score), Self-Efficacy, Five Times Sit-to-Stand Test time, Pain, or Proprioception. The results of the different studies did not find significant changes in the intervention groups with exergames in the physical domains, especially in studies with shorter interventions. Therefore, further investment in future studies on developing and evaluating games is suggested to enhance training during the recovery process.

description: Current technological solutions that enable content creation and sharing during group discussion meetings are often cumbersome to use, and are commonly abandoned for traditional paper-based tools, which provide flexibility in supporting a wide range of working styles and task activities that may occur in a given meeting. Paper-based tools, however, have their own drawbacks; paper-based content is difficult to modify or replicate. We introduce a novel digital meeting room design, the NiCE Discussion Room, which integrates digital and paper tools into a cohesive system with an intuitive pen-based interface. The combination of digital and paper media provides groups with a flexible design solution that enables them to create, access, and share information and media from a variety of sources to facilitate group discussions. This paper describes the design solution, along with results from a user study conducted to evaluate the usability and utility of the system.

Participants were recruited via email invitation from their university, direct invitation during a lecture/tutorial and advertisements on social media. Participants rated their confidence (using 4-point Likert scales) in performing 60 individual core capabilities across seven domains from an international core capability framework developed for physiotherapists delivering quality care via videoconferencing. Data were dichotomised with ‘moderately confident’ and ‘extremely confident’ deemed as ‘confident’ and ‘slightly confident’ and ‘not confident’ deemed as ‘not confident’. 343 participants from 20 (out of 25) Australian universities offering entry-to-practice physiotherapy programs completed the survey. The most common program participants were enrolled in/completed was a Bachelor of Physiotherapy (61%, n = 209). Overall, most (75–100%) participants were confident in the domain ‘delivery of telehealth’, many (51–74%) were confident in domains of ‘patient privacy and confidentiality’, ‘patient safety’, ‘assessment and diagnosis’, ‘care planning and management’, and some (25–50%) were confident in ‘technology skills’ and ‘compliance’ issues. Findings from this study highlight areas where final year entry-to-practice physiotherapy students and recent graduates may need additional support and training to deliver quality care via videoconferencing. These findings can inform the content of telehealth physiotherapy curricula.

description: To synthesise the available evidence on physical factors, such as muscle strength and power, body mass index and their association with older adults’ self-reported and performance-based mobility outcomes. This review followed the Askey and O'Malley framework. We systematically searched PubMed, EMBASE, PsychINFO, Web of Science, AgeLine, Allied and Complementary Medicine Database, and Cumulative Index to Nursing and Allied Health Literature databases, from Jan. 2000 to Jan. 2022. Teams of two reviewers independently conducted title, abstract, full-text screening, and data extraction using predefined inclusion and exclusion criteria. A total of 239 quantitative articles, mostly cross-sectional design, conducted in 32 countries were included in this review. We identified 18 physical factors significantly associated with mobility outcomes in the expected direction. Muscle strength, body composition, falls (number and history of), and chronic conditions (number of and type) were the most studied physical factors. Older adults with muscle weakness, weight concerns, history of falls, and chronic conditions had poorer mobility outcomes, such as slower gait speed, poor balance, limited community mobility and poor driving outcomes compared to their counterparts. Studies exploring the role of physical factors on the use of an assisted device, transportation, or driving, are limited.
Agile Interaction Design and Test-Driven Development of User Interfaces – A Literature Review
Creators: name: Hellmann, Theodore D.

Publisher: name: Springer
Year: 2010

description: This chapter describes the development of GUI-based applications, from usability engineering and prototyping to acceptance test-driven development, in an agile context. An overview of current agile interaction design practices will be presented, including a thorough analysis of the current role of prototyping and current attempts to facilitate test-driven development of GUI systems, as presented in academic and industrial literature. Traditional usability engineering approaches shows that if user input is taken into consideration early in the development process by repeatedly conducting usability tests on low-fidelity prototypes of the GUI system, the final version of the GUI will be both more usable and less likely to require revision. The major risk associated with test-driven development of GUIs is the high likelihood of change in the target GUI, which can make test development unnecessarily expensive and time consuming. A unification of these styles of development will be presented, along with a prediction of how this process can be used to simplify creating testable GUI-based applications by agile teams.

description: In addition to unconventional high-Tc superconductivity, the iron arsenides exhibit strong magnetoelastic coupling and a notable electronic anisotropy within the a-b plane. We relate these properties by studying underdoped Ba(Fe{1-x}Co{x})2As2 by x-ray diffraction in pulsed magnetic fields up to 27.5 Tesla. We exploit magnetic detwinning effects to demonstrate anisotropy in the in-plane susceptibility, which develops at the structural phase transition despite the absence of magnetic order. The degree of detwinning increases smoothly with decreasing temperature, and a single- domain condition is realized over a range of field and temperature. At low temperatures we observe an activated behavior, with a large hysteretic remnant effect. Detwinning was not observed within the superconducting phase for accessible magnetic fields.

Epigenetic profiling of bronchial epithelial cells : DNA methylation
Creators: name: Taplin, Christopher David
Publisher: name: University of British Columbia

description: Epigenetic regulation of gene expression is critical for normal human development and cellular differentiation. Although each somatic cell in the human body is genetically identical, epigenetic marks including the DNA methylation pattern are tissue-specific and critical for determining the vast array of cellular phenotypes. For studying respiratory disease, the airway epithelium is the ideal target tissue since it is the first point of contact for inhaled particles, viruses and airborne allergens. Cultured airway epithelial cells of asthmatic children show striking phenotypic differences compared to those from non-asthmatic individuals such as poor wound healing and enhanced expression of inflammatory cytokines. The altered state of the asthmatic epithelium could be due to underlying differences in gene expression associated with changes in their DNA methylation profile. Therefore, in this study, the purpose was to determine the extent to which DNA methylation, a reportedly stable epigenetic mark, is altered by standard cell culture conditions over passage for primary and immortalized bronchial epithelial cells. We analyzed four individual primary bronchial epithelial cell lines and a 1HBEO- immortalized bronchial epithelial cell line in triplicate. CpG DNA methylation was characterized during stages of cell propagation for 1505 CpG sites in promoter regions and/or first exons of 807 genes and compared with its gene expression. A comparison of 1HBEO- cells and primary bronchial epithelial cell lines revealed that 1HBEO- cells have significantly higher levels of overall methylation and more hyper- and heterogeneously-methylated CpG loci. In addition, there were a large number of CpG sites that had variable DNA methylation over passage in the primary cell lines but not in the immortalized cell lines. In summary, there were extensive differences in DNA methylation profiles between primary and immortalized bronchial epithelial cell lines during cell propagation, revealing the importance of this epigenetic modification in cell culture. This work is critical because, although little is known about the CpG specific changes that occur in cell culture, passaged cells are still regularly grouped together and phenotyped for major biological studies.

description: В статье рассматриваются некоторые актуальные вопросы, возникшие при построении гиггсовой модели гравитации, в частности, о гравитирующей массе, как результате взаимодействия частиц с вакуумным средним хиггсова поля. Ещё раз обращается внимание на следствие гиггсовой модели гравитации, указывающее на то, что в гравитационных взаимодействиях принимают участие только те поля и частицы, которые взаимодействуют с классическим вакуумом (конденсатом) хиггсова поля, нарушая его первоначальную однородность и изотропность тем самым становясь причиной появления градиентов в распределении частиц конденсата, и, следовательно, появления гравитационных сил. Расматриваются некоторые космологические противоречия, появляющиеся как следствие различных подходов к определению гравитирующей массы. Также в статье рассматриваются некоторые сравнения с ОТО и классической теорией Ньютона.

description: With the recent availability of state-of-the-art heavy-ion stable and radioactive beams, there has been a renew interest in the investigation of nuclear reactions with heavy ions. I first present the role of inelastic and transfer channel couplings in fusion reactions induced by stable heavy ions. Analysis of experimental fusion cross sections by using standard coupled-channel calculations is discussed. The role of multi-neutron transfer is investigated in the fusion process below the Coulomb barrier by analyzing $^{32}$S+$^{90,96}$Zr as benchmark reactions. The enhancement of fusion cross sections for $^{32}$S+$^{96}$Zr is well reproduced at sub-barrier energies by NTFus code calculations including the coupling of the neutron-transfer channels following the Zagrebaev semi-classical model. Similar effects for $^{40}$Ca+$^{90}$Zr and $^{40}$Ca+$^{96}$Zr fusion excitation functions are found. The breakup coupling in both the elastic scattering and in the fusion process induced by weakly bound stable projectiles is also shown to be crucial. In this lecture, full coupled-channel calculations of the fusion excitation functions are performed by using the breakup coupling for the more neutron-rich reaction and for the more weakly bound projectiles. I clearly demonstrate that Continuum-Discretized Coupled-Channel calculations are capable to reproduce the fusion enhancement from the breakup coupling in $^{6}$Li+$^{59}$Co.
