description: By tooling an spot-illuminated surface to control the flow of specular glints under motion, one can produce holographic view-dependent imagery. This paper presents the differential equation that governs the shape of the specular surfaces, and illustrates how solutions can be constructed for different kinds of motion, lighting, host surface geometries, and fabrication constraints, leading to some novel forms of holography.

Publisher: name: LEA - Lingue e Letterature d'Oriente e d'Occidente
Year: 2020

description: By means of an account of a number of encounters, Anna Dolfi follows, along the thread of friendship, the personality and work of one of Italy’s leading artists, whose reputation was earned by exhibitions in her native country and abroad as well as a museum bearing her name in central Sardinia. From early drawings to works concerning the landscape (some of which to be seen in unpublished photographs), from looms to the interwoven threads of her geographies, this essay reconstructs the poetics, individuality and means of expression of a creator of forms who has successfully united faithfulness to a world of origins nurtured by myths to the experimental character of visual poetry, the Italian Arte Povera (poor art) movement and land art.

description: We analyze both experimentally (where possible) and theoretically from first-principles the dielectric tensor components and crystal structure of five classes of Pbnm perovskites. All of these materials are believed to be stable on silicon and are therefore promising candidates for high-K dielectrics. We also analyze the structure of these materials with various simple models, decompose the lattice contribution to the dielectric tensor into force constant matrix eigenmode contributions, explore a peculiar correlation between structural and dielectric anisotropies in these compounds and give phonon frequencies and infrared activities of those modes that are infrared-active. We find that CaZrO_3, SrZrO_3, LaHoO_3, and LaYO_3 are among the most promising candidates for high-K dielectrics among the compounds we considered.

description: The notion that political developments in EU member states might threaten the

integrity of the organization is as old as the EU – or rather EEC – itself. European

integration was in no small part an effort by the original six member states to impose

some restrictions on their own freedom of action in the aftermath of three decades of

war and international crises. Pooling sovereignty would help Germany, Italy, France

and the three Ben-Ne-Lux states achieve peace and prosperity, and safeguard

democracy. Two of them were recent dictatorships. Enlargement in the 1970s, 1980s and

1990s brought in both long-established democracies and the recently authoritarian

Greece, Spain and Portugal. Despite one or two tense moments, such as the attempted

coup d’état in Spain in 1981, all three new democracies consolidated rapidly. The EU is

often accredited with playing an important part in this. After the collapse of the Berlin

Wall, the prospect of enlargement to a dozen or more formerly communist dictatorship

prompted new questions about how to ensure that these ex-authoritarian regimes could

take their place in the EU’s liberal democratic legal and normative system. The

immediate result was the Copenhagen Criteria, laid down in the June 1993 European

Council meeting in the Danish capital, which were designed to ensure that new member

states were liberal democracies, respected human rights, had a functioning market

economy and were capable of implementing the Acquis Communautaire. Combined with

the obligation that all member states must be members of the Council of Europe, and a

lengthy transition process, these rules should ensure that no new member state reversed

its commitment to liberal democracy, free markets and the rule of law.

Influence of core body temperature on cerebral blood flow during exercise
Creators: name: Caldwell, Hannah Grace
Publisher: name: University of British Columbia
Year: 2019

description: Introduction: Cerebral blood flow (CBF) decreases by approximately 10-15% for every 1°C rise in core temperature (Tc) during passive heat stress. Acute moderate-intensity exercise (e.g., 30- 60 mins at 50-60% workload max) also increases Tc (+0.7-0.8°C); however, likely due to small elevations in arterial PCO₂ and metabolism, such exercise increases CBF (+10-20%). This study aimed to isolate the role of Tc from PCO₂ on CBF regulation during submaximal exercise. Methods: Healthy adults (n=11; 10M/ 1F; 26±4 yrs) participated in two separate interventions: 1) 60 mins semi-recumbent cycling (EX; 50% workload max); and 2) passive heat stress (HS; 49°C water-perfused suit) timed to match the exercise-induced increases in Tc. Blood flow in the internal and external carotid (ICA and ECA, respectively) and vertebral (VA) arteries (Duplex ultrasound) was measured. End-tidal PCO₂ and PO₂ were effectively “clamped” to resting values within each condition. Results: The changes in Tc with EX and HS were matched between conditions (Δ0.76±0.24°C, P=0.855). Chest skin temperature was higher during the HS intervention (HS: Δ2.91±1.21°C vs. EX: Δ0.53±1.17°C, respectively, P<0.001), whereas increases in cheek temperature (Δ1.17±0.92°C) were not different between conditions (P=0.221). Related to this, although ECA blood flow increased during both EX and HS for thermoregulatory heat dissipation (EX: Δ42±58% vs. HS: Δ53±28%, time effect: P<0.001), there was no difference between conditions (P=0.628). Blood flow in the ICA was unchanged with EX and HS interventions (P=0.665), consistent with the unchanged end-tidal PCO₂ (P=0.327). In contrast, blood flow in the VA was higher throughout both EX and HS (EX: Δ16±21% vs. HS: Δ16±23%, time effect: P=0.006) with no between condition differences (P=0.514). These increases in VA blood flow contributed to higher global CBF throughout both EX and HS (EX: Δ12±20% vs. HS: Δ14±14%, time effect: P=0.029). Including blood pressure as a covariate did not influence these CBF findings (all P>0.05). Conclusions: These data indicate a selective influence of Tc in mediating elevations in posterior CBF during exercise that is independent of changes in PCO₂ and blood pressure.

description: We investigate electric and magnetic properties of graphene with rotationally symmetric strain. The strain generates large pseudo magnetic field with alternating sign in space, which forms a strongly confined quantum dot connected to six chiral channels. The orbital magnetism, degeneracy, and channel opening can be understood from the interplay between real and pseudo magnetic field which have different parities under time reversal and mirror reflection. While the orbital magnetic response of the confined state is diamagnetic, it can be paramagnetic if there is an accidental degeneracy with opposite mirror reflection parity.

description: The objective of the study is to study the properties of materials of surface coatings to increase the service life of machine parts. The hardness of five materials (steel 45, FK-45, FTs-16, stellite, inconel) was measured with an FM-300 automatic microhardness tester. The microstructure of the five materials was detected by a Î¼VIZO-MET-221 metallographic microscope. Results of work: it is shown that microhardness and wear resistance can be concluded about the relationship between microhardness and wear resistance. A study of the wear resistance of the materials of the claddings showed that the cladding of stellite and Inconel, which have the highest microhardness (716 HV and 544 HV), have greater wear resistance (Îµ = 56 and 33).

description: Since the pioneering work of Eichten and Lane it has been known that the scale of the interactions responsible for the generation of the strange-quark mass in extended technicolor theories must, absent any "GIM-like" mechanism for suppressing flavor-changing neutral currents, be greater than of order 1000 TeV. In this note we point out that the constraint from the neutral D-meson system is now equally strong, implying that the charm quark mass must also arise from flavor dynamics at a scale this high. We then quantify the degree to which the technicolor condensate must be enhanced in order to yield the observed quark masses, if the extended technicolor scale is of order 1000 TeV. Our results are intended to provide a framework in which to interpret and apply the results of lattice studies of conformal strongly interacting gauge theories, and the corresponding numerical measurements of the anomalous dimension of the mass operator in candidate theories of "walking" technicolor.

Disability in the gym : perceptions and understandings about individuals with disabilities
Creators: name: Zaletelj, Ljudmila
Publisher: name: University of British Columbia
Year: 2019

description: Obtaining and maintaining health is vitally important to people with disabilities, especially when you consider the fact that they report low standards of health (Carroll et al., 2014; Drum et al., 2005; WHO, 2011). One of the key reasons for their poor health conditions is their lack of engagement in physical activity and exercise (Rimmer et al., 1996; Schoenborn & Barnes, 2002; Washburn et al., 2002). Gyms have been recognized as important environments in which individuals with disabilities can engage in physical activity and exercise and positively influence several aspects of their well-being (Calder et al., 2018; Richardson et al., 2017a, 2017b, 2017c). As trainers and instructors have been recognized as an essential element of supporting positive gym experiences (Martin & Smith, 2002; Richardson et al, 2017c), it is essential to uncover their understanding of disability and individuals with disabilities. Using semi-structured qualitative interviews with 12 trainers and instructors, this research critically explored personal trainers’ and instructors’ understanding of disability and the potential impact of these perceptions and understandings on the experiences of people with disabilities when they visit the gym. The findings revealed that trainers and instructors understood disability as a lack of ability and a deviation from a common norm. Individuals with disabilities were perceived as an anomaly from the desired able-bodied standard. Moreover, the findings highlighted that fear of inability to design and implement adequate and safe training sessions posed a barrier as it discouraged trainers and instructors from working with individuals with disabilities. However, when trainers and instructors did work with clients with disabilities, they did not only have positive experiences but they also felt they developed a more holistic practice as a result of this experience.

description: We study the pair production of charged gauge bosons at the LHC in a noncommutative extension of the standard model. We use angular distributions in the decays of the gauge bosons to partially reconstruct polarized cross sections. We use this, together with CP considerations, to construct more sensitive observables that allow to separate space-time from space-space noncommutativities.

description: Fermionic formulas in combinatorial Bethe ansatz consist of sums of products of q-binomial coefficients. There exist refinements without a sum that are known to yield partition functions of box-ball systems with a prescribed soliton content. In this paper, such a refined fermionic formula is extended to the periodic box-ball system and a q-analogue of the Bethe root counting formula for XXZ chain at $Δ=\infty$.

description: We describe majorization between selfadjoint operators in a $σ$-finite II$_\infty$ factor $(\mathcal{M},τ)$ in terms of simple spectral relations. For a diffuse abelian von Neumann subalgebra $\mathcal{A}\subset \mathcal{M}$ with trace-preserving conditional expectation $E_{\mathcal{A}}$, we characterize the closure in the measure topology of the image through $E_{\mathcal{A}}$ of the unitary orbit of a selfadjoint operator in $\mathcal{M}$ in terms of majorization (i.e., a Schur-Horn theorem). We also obtain similar results for the contractive orbit of positive operators in $\mathcal{M}$ and for the unitary and contractive orbits of $τ$-integrable operators in $\mathcal{M}$.
title: Wood for the kitchen : Towards a history of the supply and use of fuelwood in an urban setting of West Africa : The case of Lome (from 1907 to 2017)

description: Despite the longstanding importance of wood as the main private domestic fuel in Togo, it was not until the official identification of the so-called fuelwood crisis in non-Western countries in the 1970s that firewood and charcoal gained attention as a critical issue for research. Consequently, foreign and national experts and natural scientists began to explore the dynamics of fuelwood energy in domestic settings in Togo. Therefore, non-historians have provided a great deal of the current knowledge about the fuelwood energy sub-sector in Togo and Lome. In reviewing the current body of literature, the raison d’être of this thesis arises from the traditional significance of wood as fuel in Togo. The study aims, therefore, to insert the historian’s point of view into the domestic energy debate in Togo. The study achieves this by examining the reasons for changes in Lome’s use, marketing and supply of fuelwood from the late nineteenth century to 2017, as well as how the fuelwood issue has been managed by colonial and post-independence authorities in charge of forest resources. More specifically, the historical investigation offers crucial historical insights into the social, economic, environmental, technological and political implications and challenges that these changes had on people at the micro and macro levels, as well as on the forest vegetation. In the same vein, the historical analysis highlights how those challenges have been addressed in different contexts and epochs by the diversity of actors involved in the realm of domestic fuelwood energy in Togo and particularly in Lome. To meet these objectives, a transdisciplinary approach has been used in which historical methods critically interact with those from other fields such as geography, anthropology, botany, and development studies. In addition, the study employed a critical triangulation of both written primary and secondary archival materials with oral and visual historical data collected during several fieldwork investigations conducted between 2016 and 2017, both within and outside Togo.

description: We have calculated the density-density (Lindhard) response function of a homogeneous two-dimensional (2D) hole gas in the static (omega=0) limit. The bulk valence-band structure comprising heavy-hole (HH) and light-hole (LH) states is modeled using Luttinger's kdotp approach within the axial approximation. We elucidate how, in contrast to the case of conduction electrons, the Lindhard function of 2D holes exhibits unique features associated with (i) the confinement-induced HH-LH energy splitting and (ii) the HH-LH mixing arising from the charge carriers' in-plane motion. Implications for the dielectric response and related physical observables are discussed.

Year: 2010

description: Breakup reactions are one of the main tools for the study of exotic nuclei, and in particular of their continuum. In order to get valuable information from measurements, a precise reaction model coupled to a fair description of the projectile is needed. We assume that the projectile initially possesses a cluster structure, which is revealed by the dissociation process. This structure is described by a few-body Hamiltonian involving effective forces between the clusters. Within this assumption, we review various reaction models. In semiclassical models, the projectile-target relative motion is described by a classical trajectory and the reaction properties are deduced by solving a time-dependent Schroedinger equation. We then describe the principle and variants of the eikonal approximation: the dynamical eikonal approximation, the standard eikonal approximation, and a corrected version avoiding Coulomb divergence. Finally, we present the continuum-discretized coupled-channel method (CDCC), in which the Schroedinger equation is solved with the projectile continuum approximated by square-integrable states. These models are first illustrated by applications to two-cluster projectiles for studies of nuclei far from stability and of reactions useful in astrophysics. Recent extensions to three-cluster projectiles, like two-neutron halo nuclei, are then presented and discussed. We end this review with some views of the future in breakup-reaction theory.

description: In this work we investigate higher order statistics for the $\lcdm$ and ReBEL scalar-interacting dark matter models by analyzing $180\hmpc$ dark matter N-body simulation ensembles. The N-point correlation functions and the related hierarchical amplitudes, such as skewness and kurtosis, are computed using the Count-In-Cells method. Our studies demonstrate that the hierarchical amplitudes $S_n$ of the scalar-interacting dark matter model significantly deviate from the values in the $\lcdm$ cosmology on scales comparable and smaller then the screening length $r_s$ of a given scalar-interacting model. The corresponding additional forces that enhance the total attractive force exerted on dark matter particles at galaxy scales lowers the values of the hierarchical amplitudes $S_n$. We conclude that hypothetical additional exotic interactions in the dark matter sector should leave detectable markers in the higher-order correlation statistics of the density field. We focussed in detail on the redshift evolution of the dark matter field's skewness and kurtosis. From this investigation we find that the deviations from the canonical $\lcdm$ model introduced by the presence of the ``fifth'' force attain a maximum value at redshifts $0.5

description: In this invited talk I discuss two recent applications of charmonium (Psi) decays to N Nbar m final states, where N is a nucleon and m is a light meson. There are several motivations for studying these decays: 1) They are useful for the study of N* spectroscopy; 2) they can be used to estimate cross sections for the associated charmonium production processes p pbar to Psi m, which PANDA plans to exploit in searches for charmonium hybrid exotics; and 3) they may allow the direct experimental measurement of NNm (meson-nucleon) strong couplings, which provide crucial input information for meson exchange models of the NN force. The latter two topics are considered in this talk, which will also compare results from a simple hadron pole model of these decays to recent experimental data.

Etant donné que le nombre d’examens CT est en forte augmentation chaque année, le nombre d’injection est accru, tout comme le nombre d’extravasations. L’extravasation due à une injection du produit de contraste iodé peut avoir de sérieuses conséquences sur la santé du patient. Cette étude permet d’observer et d’analyser le taux et le volume d’extravasation en lien avec un changement de cathéter pour ensuite comparer les résultats avec la littérature. En connaissant mieux les facteurs de risques, nous pouvons être plus vigilants à la pratique professionnelle afin de diminuer le taux et le volume extravasé. La méthodologie permet le suivi du taux d’extravasation sur un an. Elle est prévue dans un hôpital universitaire où le nombre d’injections par année se trouve aux alentours de 20'000 à 25'000 injections. Tous les examens de tomodensitométrie du service radiologique utilisant une injection intraveineuse du produit de contraste et un cathéter du modèle Nexiva™ Diffusics™ seront inclus dans cette étude. Un formulaire contenant les informations ayant trait à l’extravasation et aux facteurs de risques de l'extravasation sera rempli par le technicien en radiologie médicale.
Drought influences mixed-severity fire regimes across temporal and spatial scales in the Montane Cordillera of Canada

Publisher: name: University of British Columbia
Year: 2019

description: Understanding historical fire-drought associations, particularly in forests with mixed-severity fire regimes, is a research and fire management priority in western North America. My thesis investigates how drought variation across temporal and spatial scales drove such fire regimes in the Montane Cordillera of Canada. I developed three-interrelated studies written as independent chapters, all of which used crossdated fire-scars to represent historical fire years. The first two studies test fire-drought associations using monthly adaptations of the Drought Code (DC) from Canada’s Fire Weather Index System. First, I compared three monthly drought codes during the 20th and 21st centuries for montane forests of southeast British Columbia. Accuracy of monthly DC increased after accounting for overwinter drying, early fire season starts, and effective precipitation. June-August drought codes were significantly associated with historical fires. Variation in fire-season drought influenced fire severity, connecting modern fire-weather indices with historical mixed-severity fire regimes. Second, I investigated how historical drought variation drove mixed-severity fire regimes in the same location by developing a tree-ring proxy reconstruction of summer DC. Comparing summer DC against a local summer Palmer Drought Severity Index provided a nuanced understanding of inter-annual fire-drought associations and moisture content among forest fuels, namely in deep compact organics in the soil and large woody fuels, versus the duff layer. Fire years were associated with coinciding and previous year summer drought; but limited by coinciding and previous year summer wet conditions. Summer moisture conditions during fire years likely influenced ignitions and led to variable combustion of forest fuels. The final study encompassed broader spatial coverage by including 17 fire-history sites across the Montane Cordillera, and by testing historical associations between climate and fire based on years with evidence of fire at multiple sites, i.e., fire synchrony. Fire synchrony was historically common, and associated with droughts at regional and subregional scales based on tree-ring proxy reconstructions of climate. My thesis provides information on drought as a driver of mixed-severity fire regimes across temporal and spatial scales. Ultimately, understanding how drought drove mixed-severity fire regimes across scales, helps fire managers anticipate how these fire regimes are shifting due to climate change.

description: Using effective field theory (EFT) techniques we calculate the next-to-leading order (NLO) spin-orbit contributions to the gravitational potential of inspiralling compact binaries. We use the covariant spin supplementarity condition (SSC), and explicitly prove the equivalence with previous results by Faye et al. in arXiv:gr-qc/0605139. We also show that the direct application of the Newton-Wigner SSC at the level of the action leads to the correct dynamics using a canonical (Dirac) algebra. This paper then completes the calculation of the necessary spin dynamics within the EFT formalism that will be used in a separate paper to compute the spin contributions to the energy flux and phase evolution to NLO.

By using the diagrammatic method, we develop a general formalism to systematically construct the similar inequalities up to any order correlation function. As an application, we explicitly derive all the inequalities up to six and eight-point functions.

description: Wireless Sensor Networks (WSNs) generate massive amount of live data and events sensed through dispersedly deployed tiny sensors. This generated data needed to be disseminate to the sink with slight consumption of network resources. One of the ways to efficiently transmit this bulk data is gossiping. An important consideration in gossip-based dissemination protocols is to keep routing table up to date. Considering the inherent resource constrained nature of adhoc wireless sensor networks, we propose a gossip based protocol that consumes little resources. Our proposed scheme aims to keep the routing table size R as low as possible yet it ensures that the diameter is small too. We learned the performance of our proposed protocol through simulations. Results show that our proposed protocol attains major improvement in network reachability and connectivity.

description: The languages accepted by finite automata are precisely the languages denoted by regular expressions. In contrast, finite automata may exhibit behaviours that cannot be described by regular expressions up to bisimilarity. In this paper, we consider extensions of the theory of regular expressions with various forms of parallel composition and study the effect on expressiveness. First we prove that adding pure interleaving to the theory of regular expressions strictly increases its expressiveness up to bisimilarity. Then, we prove that replacing the operation for pure interleaving by ACP-style parallel composition gives a further increase in expressiveness. Finally, we prove that the theory of regular expressions with ACP-style parallel composition and encapsulation is expressive enough to express all finite automata up to bisimilarity. Our results extend the expressiveness results obtained by Bergstra, Bethke and Ponse for process algebras with (the binary variant of) Kleene's star operation.

description: We calculate the decay widths of both the second and the third radial excitations of $η$ and $η'$ within the framework of $^3P_0$ model. After comparing the theoretical decay widths and decay patterns with the available experimental data of $η(1760)$, $X(1835)$, $X(2120)$ and $X(2370)$, we find that the interpretation of $η(1760)$ and $X(1835)$ as the second radial excitation of $η$ and $η'$ crucially depends on the measured mass and width of $η(1760)$, which is still controversial experimentally. We suggest that there may be sizable $p\bar{p}$ content in $X(1835)$. $X(2120)$ and $X(2370)$ can not be understood as the third radial excitations of $η$ and $η'$, $X(2370)$ probably is a mixture of $η'(4{^1}{S}{_0})$ and glueball.

Holonomies of gauge fields in twistor space 4: functional MHV rules and one-loop amplitudes

description: We consider generalization of the Cachazo-Svrcek-Witten (CSW) rules to one-loop amplitudes of N=4 super Yang-Mills theory in a recently developed holonomy formalism in twistor space. We first reconsider off-shell continuation of the Lorentz-invariant Nair measure for the incorporation of loop integrals. We then formulate an S-matrix functional for general amplitudes such that it implements the CSW rules at quantum level. For one-loop MHV amplitudes, the S-matrix functional correctly reproduces the analytic expressions obtained in the Brandhuber-Spence-Travaglini (BST) method. Motivated by this result, we propose a novel regularization scheme by use of an iterated-integral representation of polylogarithms and obtain a set of new analytic expressions for one-loop NMHV and N$^2$MHV amplitudes in a conjectural form. We also briefly sketch how the extension to one-loop non-MHV amplitudes in general can be carried out.

description: We introduce a new criterion, replacement freeness, to discern the relative expressiveness of process calculi. Intuitively, a calculus is strongly replacement free if replacing, within an enclosing context, a process that cannot perform any visible action by an arbitrary process never inhibits the capability of the resulting process to perform a visible action. We prove that there exists no compositional and interaction sensitive encoding of a not strongly replacement free calculus into any strongly replacement free one. We then define a weaker version of replacement freeness, by only considering replacement of closed processes, and prove that, if we additionally require the encoding to preserve name independence, it is not even possible to encode a non replacement free calculus into a weakly replacement free one. As a consequence of our encodability results, we get that many calculi equipped with priority are not replacement free and hence are not encodable into mainstream calculi like CCS and pi-calculus, that instead are strongly replacement free. We also prove that variants of pi-calculus with match among names, pattern matching or polyadic synchronization are only weakly replacement free, hence they are separated both from process calculi with priority and from mainstream calculi.
