Implications for Minimal Supersymmetry from Grand Unification and the Neutralino Relic Abundance

description: We examine various predictions of the minimal supersymmetric standard model coupled to minimal supergravity. The model is characterised by a small set of parameters at the unification scale. The supersymmetric particle spectrum at low energy and the spontaneous breaking of the standard model itself are then generated radiatively. The previously considered predictions of the model now include the neutralino relic density which in turn provides bounds on the scale parameters. We find a remarkable consistency among several different constraints which imply all supersymmetric particle masses preferably within the reach of future supercolliders (LHC and SSC). The requirement that the neutralino be the dominant component of (dark) matter in the flat Universe provides a {\em lower} bound on the spectrum of supersymmetric particles beyond the reach of LEP, and most likely also the Tevatron and LEP 200.

description: Even though motion planning for automated vehicles has been extensively discussed for more than two decades, it is still a highly active field of research with a variety of different approaches having been published in the recent years. When considering the market introduction of SAE Level 3+ vehicles, the topic of motion planning will most likely be subject to even more detailed discussions between safety and user acceptance. This paper shall discuss parameters of the motion planning problem and requirements to an environment model. The focus is put on the representation of different types of uncertainty at the example of sensor occlusion, arguing the importance of a well-defined interface between decision making and trajectory generation.

description: We consider the problem of controlling a Linear Quadratic Regulator (LQR) system over a finite horizon $T$ with fixed and known cost matrices $Q,R$, but unknown and non-stationary dynamics $\{A_t, B_t\}$. The sequence of dynamics matrices can be arbitrary, but with a total variation, $V_T$, assumed to be $o(T)$ and unknown to the controller. Under the assumption that a sequence of stabilizing, but potentially sub-optimal controllers is available for all $t$, we present an algorithm that achieves the optimal dynamic regret of $\tilde{\mathcal{O}}\left(V_T^{2/5}T^{3/5}\right)$. With piece-wise constant dynamics, our algorithm achieves the optimal regret of $\tilde{\mathcal{O}}(\sqrt{ST})$ where $S$ is the number of switches. The crux of our algorithm is an adaptive non-stationarity detection strategy, which builds on an approach recently developed for contextual Multi-armed Bandit problems. We also argue that non-adaptive forgetting (e.g., restarting or using sliding window learning with a static window size) may not be regret optimal for the LQR problem, even when the window size is optimally tuned with the knowledge of $V_T$. The main technical challenge in the analysis of our algorithm is to prove that the ordinary least squares (OLS) estimator has a small bias when the parameter to be estimated is non-stationary. Our analysis also highlights that the key motif driving the regret is that the LQR problem is in spirit a bandit problem with linear feedback and locally quadratic cost. This motif is more universal than the LQR problem itself, and therefore we believe our results should find wider application.

Improving Understanding and Trust with Intelligibility in Context-Aware Applications
Creators: name: Lim, Brian Y.
Publisher: name: Carnegie Mellon University
Year: 2012
Subjects: Applied Computer Science

description: To facilitate everyday activities, context-aware applications use sensors to detect what is happening and use increasingly complex mechanisms (e.g., by using big rule-sets or machine learning) to infer the user's context and intent. For example, a mobile application can recognize that the user is in a conversation and suppress any incoming calls. When the application works well, this implicit sensing and complex inference remain invisible. However, when it behaves inappropriately or unexpectedly, users may not understand its behavior. This can lead users to mistrust, misuse, or even abandon it. To counter this lack of understanding and loss of trust, context-aware applications should be intelligible, capable of explaining their behavior. We investigate providing intelligibility in context-aware applications and evaluate its usefulness to improve user understanding and trust in context-aware applications. Specifically, this thesis supports intelligibility in context-aware applications through the provision of explanations that answer different question types, such as: Why did it do X? Why did it not do Y? What if I did W, What will it do? How can I get the application to do Y? This thesis takes a three-pronged approach to investigating intelligibility by (i) eliciting the user requirements for intelligibility, to identify what explanation types end-users are interested in asking context-aware applications, (ii) supporting the development of intelligible context-aware applications with a software toolkit and the design of these applications with design and usability recommendations, and (iii) evaluating the impact of intelligibility on user understanding and trust under various situations and application reliability, and measuring how users use an interactive intelligible prototype. We show that users are willing to use well-designed intelligibility features, and this can improve user understanding and trust in the adaptive behavior of context-aware applications.

Specifically, using the critical point analysis we study the existence and the stability of singular solutions which describe de-Sitter, radiation and matter dominated eras. We find several classes of $Λ(H)$ cosmologies for which new analytical solutions are given in terms of Laurent expansions. Finally, we show that the Milne universe and the $R_{h}=ct$ model can be seen as perturbations around a specific $Λ(H)$ model, but this model is unstable.

description: Subgenus Thyanta Stal
Diagnosis. Punctures minute, dense. Posterior termination ofbucculae evanescent. Anterolateral pronotal margins straight to concave, sometimes marked with piceous; each humeral angle rounded to angulate, often spinose; pronotal cicatrices sometimes marked with piceous in mesial angles. Ostiolar canals acuminate apically. Superior surface of each tibia sulcate.
Posterior margins of basal plates sinuous, posteromesial angles entire (Fig. 13). Distal end of sclerotized rod cone-shaped (Fig. 14); spermathecal bulb digitiform; cylindrical structure present below proximal flange (Fig. 15).
Pygophoral opening small, subtended on posteroventral surface by a rectangular or semicircular impression; posterior margin of pygophore straight to concave in caudal view, with medially incised protuberance in middle (Fig. 9). Each paramere F-shaped, obtuse protuberance on shaft usually prominent, apex spinose, ectal surface convex (Fig. 3), roughened spiculate area on lateral surface linear (Fig. 4). Each lateral conjunctival lobe of aedeagus with single spinose diverticulum (Fig. 6); dorsomedial conjunctiva} lobe usually well-developed (Fig. 7); theca large, subtriangular in lateral view, with dorsolateral protuberance on each side near caudal limit (Fig. 8); medial penial lobes and penisfilum moderate in size.
Comments. Species of the subgenus Thyanta have the pygophoral opening subtended by a semicircular or rectangular impression, and the posterior margin is distinctly emarginate medially. Species of Phacidium have the posteroventral surface of the pygophore arcuately rounded or sulcate, and the posterior margin not emarginate medially. The posteroventral surface of the pygophore in species of Argosoma is produced into a blunt chin-like protuberance. Also, species of Argosoma have the ectal surface of each paramere concave, while it is convex in both Phacidium and Thyanta.
The female genitalia are also useful in separating species of Thyanta and Phacidium. In Thyanta the distal end of the sclerotized rod is cone-shaped, and the spermathecal bulb is digitiform. In Phacidium the distal end of the sclerotized rod is swollen subapically and narrowed distally, and the spermathecal bulb is globose. The female genitalia of both Phacidium and Argosoma are very similar, but females can usually be separated by the relative density of the dorsal punctation. The dorsal punctation is relatively dense in Phacidium, while it is less dense and more coarse in Argosoma.

description: We study the interaction between various analytification functors, and a class of morphisms of rings, called homotopy epimorphisms. An analytification functor assigns to a simplicial commutative algebra over a ring $R$, along with a choice of Banach structure on $R$, a commutative monoid in the monoidal model category of simplicial ind-Banach $R$-modules. We show that several analytifications relevant to analytic geometry - such as Tate, overconvergent, Stein analytification, and formal completion - are homotopy epimorphisms. Another class of examples arises from Weierstrass, Laurent and rational localisations in derived analytic geometry. As applications of this result, we prove that Hochschild homology and the cotangent complex are computable for analytic rings, and the computation relies only on known computations of Hochschild homology for polynomial rings. We show that in various senses, Hochschild homology as we define it commutes with localizations, analytifications and completions.

description: I discuss gauge coupling unification in a class of superstring standard--like models, which are derived in the free fermionic formulation. Recent calculations indicate that the superstring unification scale is at $O(10^{18}GeV)$ while the minimal supersymmetric standard model is consistent with LEP data if the unification scale is at $O(10^{16})GeV$. A generic feature of the superstring standard--like models is the appearance of extra color triplets $(D,{\bar D})$, and electroweak doublets $(\ell,{\bar\ell})$, in vector--like representations, beyond the minimal supersymmetric standard model. I show that gauge coupling unification at $O(10^{18}GeV)$ in the superstring standard--like models can be consistent with LEP data. I present an explicit standard--like model that can realize superstring gauge coupling unification.

description: We study the first non-planar correction to gluon scattering amplitudes in ${\cal N}=4$ SYM theory. The correction takes the form of a double trace partial amplitude and is suppressed by one power of $1/N$ with respect to the leading single trace contribution. We extend the duality between planar scattering amplitudes and null polygonal Wilson loops to the double trace amplitude. The new duality relates the amplitude to the correlation function of two infinite null polygonal Wilson lines that are subject to a quantum periodicity constraint. We test the duality perturbatively at one-loop order and demonstrate it for the dual string in AdS. The duality allows us to extend the notion of the loop integrand beyond the planar limit and to determine it using recursion relations. It also allows one to apply the integrability-based pentagon operator product expansion approach to the first non-planar order.

description: In this contribution, we investigate the potential of hyperspectral data combined with either simulated ground penetrating radar (GPR) or simulated (sensor-like) soil-moisture data to estimate soil moisture. We propose two simulation approaches to extend a given multi-sensor dataset which contains sparse GPR data. In the first approach, simulated GPR data is generated either by an interpolation along the time axis or by a machine learning model. The second approach includes the simulation of soil-moisture along the GPR profile. The soil-moisture estimation is improved significantly by the fusion of hyperspectral and GPR data. In contrast, the combination of simulated, sensor-like soil-moisture values and hyperspectral data achieves the worst regression performance. In conclusion, the estimation of soil moisture with hyperspectral and GPR data engages further investigations.

description: In this Letter the method of Lund is applied to formulate a variational principle for the motion of charged vortices in an effective non-linear Schrödinger field theory describing finite size two-dimensional quantum Hall samples under the influence of an arbitrary perpendicular magnetic field. Freezing out variations in the modulus of the effective field yields a $U(1)$ sigma-model. A duality transformation on the sigma-model reduces the problem to finding the Green function for a related electrostatics problem. This duality illuminates the plasma analogy to the Laughlin wave function.

description: The Expectation Maximization (EM) algorithm is a method for learning the parameters of probabilistic graphical models when there is hidden or missing data. The goal of an EM algorithm is to estimate a set of parameters that maximizes the likelihood of the data. In spite of its success in practice, the EM algorithm has several limitations, including slow convergence, computational complexity, and inability to escape local maxima. Using multiple random starting points is a popular approach to mitigate the local maxima problem, but this method is time consuming. This work seeks to improve the understanding and performance of the EM algorithm. We combine evolutionary algorithms, which make use of stochastic search, with the multiple random starting points strategy for the EM algorithm. First, we propose a genetic algorithm for expectation maximization (GAEM), where we combine the global search property of genetic algorithms (GAs) and the local search property of EM. We investigate how different choices of population sizes, crossover and mutation probabilities, and selection techniques affect the solution quality. We found that small population sizes are sufficient to produce high solution quality and considerable speed-up compared to the traditional EM algorithm. Second, we develop an age-layered EM algorithm (ALEM), where we incorporate an age-layered population structure heuristic in which age is the number of iterations of an EM run. We focus on speeding up the EM algorithm for Bayesian networks. ALEM enables comparisons between similarly aged EM runs and discards less promising EM runs well before their convergence. Experimentally, we find that ALEM can significantly reduce the average number of iterations with no or minimal degradation in solution quality. Finally, we introduce an intuitive graphical user interface (GUI) to visualize and analyze graphs including Bayesian networks. In particular, the user can perform multi-focus zooming wherein he or she can compare multiple nodes in an overview graphical window and study their parameters in detail windows. For EM learning, this GUI helps to understand the progress of the estimated probability parameters.

description: The spin transfer torque (STT) can lead to steady precession of magnetization without any external applied field in magnetic spin valve where the magnetic layer have very different spin diffusion length. This effect is associated with an unusual angular dependence of the STT, called "wavy" (WAD-STT), predicted in the frame of diffusive models of spin transfer. In this article, we present a complete experimental characterization of the magnetization dynamics in the presence of a WAD-STT. The results are compared to the prediction of the magnetization dynamics obtained by single domain magnetic simulations (macrospin approximation). The macrospin simulations well reproduced the main static and dynamical experimental features (phase diagram, R(I) curves, dependence of frequency with current and field) and suggest that the dynamical excitations observed experimentally are associated with a large angle out-of-plane precession mode. The present work validates the diffusive models of the spin transfer and underlines the role of the spin accumulation and the spin relaxation effects on the STT.

description: We revise the problem of extracting one independent component from an instantaneous linear mixture of signals. The mixing matrix is parameterized by two vectors, one column of the mixing matrix and one row of the de-mixing matrix. The separation is based on the non-Gaussianity of the source of interest, while the other background signals are assumed to be Gaussian. Three gradient-based estimation algorithms are derived using the maximum likelihood principle and are compared with the Natural Gradient algorithm for Independent Component Analysis and with One-unit FastICA based on negentropy maximization. The ideas and algorithms are also generalized for the extraction of a vector component when the extraction proceeds jointly from a set of instantaneous mixtures. Throughout the paper, we address the problem of the size of the region of convergence for which the algorithms guarantee the extraction of the desired source. We show how that size is influenced by the ratio of powers of the sources within the mixture. Simulations confirm this observation where several algorithms are compared. They show various convergence behavior in a scenario where the source of interest is dominant or weak. Here, our proposed modifications of the gradient methods taking into account the dominance/weakness of the source show improved global convergence property.

description: The volume of video data collected will only increase as the prevalence of automated systems continues to grow and those systems start to rely more on vision sensors to make decisions. Visual tracking is the process of automatically estimating the location of an object through the course of a video. The ability to track objects in video is useful in applications such as autonomous driving, surveillance, and robotics. The ability to track objects allows for more effective decision making processes for tasks such as predictive driving, anomaly detection, and face recognition. With the amount of data to parse and the benefits of doing so accurately, the need for fast and reliable visual tracking is clear. Correlation filters, previously used in detection and recognition tasks within single images, have become a popular approach to visual tracking because of their ability to efficiently match and align two images. Correlation filters have been adapted for visual tracking by developing incremental learning techniques, allowing efficient updating of correlation filters. Tracker elements such as more powerful feature representations and improved scale tolerance have led to state-of-the-art tracking performance. Still, despite the recent improvements in correlation filter trackers, there remain unexplored aspects of the union of correlation filters and visual tracking. This work explores alternative correlation filter designs that have not previously been adapted to visual tracking. We also introduce an occlusion detection system to address situations where the targets are temporarily not visible; one of the most challenging aspects of tracking. We validate our approaches on widely used benchmarks while also introducing a new evaluation metric that reflects the amount of activity that occurs within a given video.

description: We study dual strong coupling description of integrability-preserving deformation of the $O(N)$ sigma model. Dual theory is described by a coupled theory of Dirac fermions with four-fermion interaction and bosonic fields with exponential interactions. We claim that both theories share the same integrable structure and coincide as quantum field theories. We construct a solution of Ricci flow equation which behaves in the UV as a free theory perturbed by graviton operators and show that it coincides with the metric of the $η-$deformed $O(N)$ sigma-model after $T-$duality transformation.

description: University of Helsinki runs a relatively complex DSpace-based E-thesis service. The service utilizes workflows and enables submission of Master's and Bachelor Theses for review, the review process of the theses as well as storing and publishing of the theses. During the past five years the E-thesis service has been developed in ever closer cooperation between the University Library and the Student Administration. During that period about 10000 Theses have been submitted, evaluated and stored using the system. We argue that this collaboration has been very beneficial, even necessary for the successful development of the service to meet the demands of the faculties, the administration and the library. The close involvement of the student services means that the development has been able to tap into the user feedback and networks available in the administration. From a broader perspective, our experience shows the benefits of inter-unit collaboration in developing and maintaining repository services. There are many types of resources and expertise, which can be combined in a fruitful way in the collaborative approach.

description: In ${\cal N}=5, 6, 8$ supergravities there are hidden symmetries of equations of motion, described by duality groups $SU(1,5), \, SO^*(12), \, E_{7(7)}$ respectively. UV divergences and known candidate counterterms violate the deformed duality symmetry current conservation. Extra higher derivative terms in the action are required to restore duality. We study the effect of a two-vector part of the counterterm for ${\cal N}\geq 5$ supergravities using the universality of the symplectic structure of extended supergravities. We construct a compact form of a deformed action with infinite number of higher derivative terms and restored duality symmetry with deformation parameter $λ$. We find, in $λ^2$ approximation, that the $SU({\cal N})$ symmetry of the deformed theory is restored on shell.

description: A search is presented for the associated production of a Higgs boson with a top quark pair in the all-jet final state. Events containing seven or more jets are selected from a sample of proton-proton collisions at $\sqrt{s} =$ 13 TeV collected with the CMS detector at the LHC in 2016, corresponding to an integrated luminosity of 35.9 fb$^{-1}$. To separate the $\mathrm{t}\overline{\mathrm{t}}$H signal from the irreducible $\mathrm{t}\overline{\mathrm{t}}+\mathrm{b}\overline{\mathrm{b}}$ background, the analysis assigns leading order matrix element signal and background probability densities to each event. A likelihood-ratio statistic based on these probability densities is used to extract the signal. The results are provided in terms of an observed $\mathrm{t}\overline{\mathrm{t}}$H signal strength relative to the standard model production cross section $μ=σ/σ_\mathrm{SM}$, assuming a Higgs boson mass of 125 GeV. The best fit value is $\hatμ =$ 0.9 $\pm$ 0.7 (stat) $\pm$ 1.3 (syst) = 0.9 $\pm$ 1.5 (tot), and the observed and expected upper limits are, respectively, $μ

“Split With the Kind Knife”: The Regenerative Excisions of Jordan Abel’s The Place of Scraps
Creators: name: Karpinski, Max
Publisher: name: Canadian Literature
Year: 2017

description: Pointedly engaging the centuries of settler-invader attempts to dispossess and destroy Indigenous communities, Nisga’a poet Jordan Abel makes appropriation and erasure his central thematic and formal preoccupations in The Place of Scraps (2013). The text itself is a series of erasure poems and collages that takes much of its source material from the Québécois anthropologist and salvage ethnographer Marius Barbeau’s canonical Totem Poles (1950). Barbeau, both in Totem Poles and throughout his career, studied a number of Pacific Northwest tribes, including the Nisga’a. At the same time as The Place of Scraps represents a defiant assertion of resistance, it also illustrates a regenerative desire, responding to recent and urgent calls, by Indigenous scholars and activists such as Taiaiake Alfred, for the reassertion and resurgence of Indigeneity in the present moment.

The Rhetoric of Silence in Life Among the Qallunaat
Creators: name: Martin, Keavy
Publisher: name: Canadian Literature
Year: 2017

description: This paper explores the rhetoric of silence in Mini Aodla Freeman’s Life Among the Qallunaat. Partway through this memoir, the author shares a parable about a government man who, having spent significant time in the North, adopts Inuit ways, becoming “Inuk-washed.” The marker of this man’s transformation is his decision not to speak back to his superiors; instead, “he chooses to be quiet and to sit back and listen.” This learned behaviour resonates with other silences in the book: the narrator is characterized by her refusal and sometimes inability to speak up; meanwhile, Aodla Freeman has since alluded to what was not included in her book (the full history of her experience at residential school). And while these decisions not to speak reflect Inuit cultural protocols around deference to authority, they also challenge a 21st century audience reading this text in the era of Truth & Reconciliation—a time, after all, of ‘breaking the silence’ and of speaking back. What are readers to make, then, of Aodla Freeman’s insistence upon silence as a commendable act? How are qallunaat to emulate the silence of the government man, especially when it risks complicity with oppression? I argue that Life Among the Qallunaat re-figures silence not only as a form of resistance to the expected ‘confession’ of traumatic experience (Garneau), but also as a rhetorical tool capable of inspiring reflection and even alliance where, previously, there was none.

Material Connections in Skawennati’s Digital Worlds
Creators: name: Leggatt, Judith Ann
Publisher: name: Canadian Literature
Year: 2017

description: This paper will examine the possibilities of Indigenous internet community by placing the work of Mohawk media artist Skawennati Tricia Fragnito in the framework of the cyberpunk genre, which imagines the ways in which human people interact with machine and digital spaces, and how those connections change both individuals and societies. By comparing Imagining Indians in the 25th Century and TimeTravellerTM with Neal Stephenson’s Snow Crash, which Skawennati references in both texts, I will show how Skawennati Indigenizes understandings of the supposedly “new world” of cyberspace. Overcoming the biases embedded in technology can create maps and pathways through which Indigenous artists and activists can change human social systems, creating new avenues for community engagement.

Beyond Comparison: Reading Relations Between Indigenous Nations
Creators: name: Wakeham, Pauline
Publisher: name: Canadian Literature
Year: 2017

description: While much has been said about the supposed tensions between literary nationalist and cosmopolitanist approaches to Indigenous literary scholarship, much less attention has been devoted to imagining how, in literary critical practice, scholars might formulate reading methods that mobilize the important insights of Native literary nationalism for the project of reading what Māori scholar Alice Te Punga Somerville calls “Indigenous-Indigenous encounter[s]” (Somerville “The Lingering” 23). The objective of this essay is to derive one possible methodological approach from Indigenous literature itself while engaging with Indigenous scholarship along the way. By reading Indigenous literature for what it teaches about critical methods, I seek to translate Native literary nationalism’s call for prioritizing Indigenous knowledges and methods into a reading practice that attends carefully to how Indigenous literary texts articulate, on their own terms, interactions with other Indigenous communities. An attention to such interactions may, in turn, contribute to the most inclusive versions of Native literary nationalism, demonstrating how distinct, local forms of Indigenous nationhood may be strengthened and enriched, rather than diluted, through exchanges across diverse Indigenous cultures. Reading relations between Indigenous nations thus opens pathways to other worlds of belonging breathed to life in Indigenous stories.

Chern-Simons Gauge Theory As A String Theory
Creators: name: Witten, Edward
Publisher: name: arXiv
Year: 1992

description: Certain two dimensional topological field theories can be interpreted as string theory backgrounds in which the usual decoupling of ghosts and matter does not hold. Like ordinary string models, these can sometimes be given space-time interpretations. For instance, three-dimensional Chern-Simons gauge theory can arise as a string theory. The world-sheet model in this case involves a topological sigma model. Instanton contributions to the sigma model give rise to Wilson line insertions in the space-time Chern-Simons theory. A certain holomorphic analog of Chern-Simons theory can also arise as a string theory.

description: Ο σχεδιασμός των κατοικιών φαινομενικά εξυπηρετεί τις ανάγκες των ανθρώπων προσφέροντάς τους χώρους για τις καθημερινές τους δραστηριότητες χωρίς όμως πάντα να καταφέρνουν αυτοί οι χώροι να πετυχαίνουν τον στόχο για τον οποίο σχεδιάστηκαν. Αυτό συμβαίνει κυρίως διότι στον σχεδιασμό δεν λαμβάνονται υπόψιν και επομένως δεν συμπεριλαμβάνονται οι ανάγκες των δραστηριοτήτων (ποιοτικά χαρακτηριστικά).
Με βάση τα παραπάνω, η ερευνητική επικεντρώνεται στην κατανόηση των δραστηριοτήτων που εξελίσσονται στην κατοικία και στον τρόπο που αυτές επηρεάζουν τον σχεδιασμό της.
Πιο συγκεκριμένα, η έρευνα αναλύει και επικεντρώνεται σε τρία χαρακτηριστικά:
-Τις βασικές δραστηριότητες που εξελίσσονται στην κατοικία.
-Τους χώρους της κατοικίας που γίνονται αυτές οι δραστηριότητες.
-Τα ποιοτικά χαρακτηριστικά που χρειάζεται να έχει ο κάθε χώρος για να επιτευχθεί και η αντίστοιχη δραστηριότητα που εξελίσσεται σε αυτόν.
Στην διαδικασία της έρευνας, έχουν επιλεγεί διαφορετικά παραδείγματα κατοικιών μεταβαλλόμενων και μη, μικρών και μεγάλων για να διαπιστωθεί ποιο είδος κατοικίας εξασφαλίζει καλύτερα αποτελέσματα στο αν οι χώροι πληρούν τα ποιοτικά χαρακτηριστικά του χρειάζεται κάθε δραστηριότητα.
Leanne Betasamosake Simpson’s Decolonial Aesthetics: “Leaks”/Leaks, Storytelling, Community, and Collaboration
Creators: name: Lacombe, Michele
Publisher: name: Canadian Literature
Year: 2017

description: In Centering Anishinaabeg Studies: Understanding the World through Stories (2013), Jill Doerfler, Niigaan Sinclair and Heidi Stark state that stories are “being used as theoretical frameworks guiding questions” in a number of fields. Anishinaabeg scholars have been “exploring issues and interests of their own communities” in ways that reveal “stories operating as different entryways . . . [and as] centres to Anishinaabeg Studies.” Doerfler et al note that in Leanne Simpson’s contribution to their volume, she approaches aadizookanaag and dibaajimowinan as “two types of stories” that reflect “interrelated forces, echoes, and parts of a greater whole.” Simpson’s poem “leaks” – like Cara Mumford’s short film Leaks – also reflect this approach. The performance of “Leaks” in the film Leaks is consistent with “spontaneous” resurgent eruptions of flash round dances associated with Idle No More; long-standing “grass-roots” forms of cultural, political and spiritual resistance; “traditional,” land-based Indigenous knowledge, language and spirituality; and contemporary Indigenous literary theory. My own reading of the poem views it as embodying new kinds of conversations between Anishinaabeg artists, but also between writers from different First Nations as well as between Indigenous and settler readers and critics.

Calculations of coherent two-dimensional electronic spectra using forward and backward stochastic wavefunctions

description: Within the well-established optical response function formalism, a new strategy with the central idea of employing the forward-backward stochastic Schrödinger equations in a segmented way to accurately obtain the two-dimensional (2D) electronic spectrum is presented in this paper. Based on the simple excitonically coupled dimer model system, the validity and efficiency of the proposed schemes are demonstrated in detail, along with the comparison against the deterministic hierarchy equations of motion and perturbative second order time-convolutionless quantum master equations. In addition, an important insight is provided in this paper that the characteristic frequency of the overdamped environment is an extremely crucial factor to regulate the lifetimes of the oscillating signals in 2D electronic spectra and of quantum coherence features of system dynamics. It is worth noting that the proposed scheme benefiting from its stochastic nature and wavefunction framework and many other advantages of substantially reducing the numerical cost, has a great potential to systematically investigate various quantum effects observed in realistic large-scale natural and artificial photosynthetic systems.
