description: With the proliferation of modern high-resolution measuring instruments mounted on satellites, planes, ground-based vehicles and monitoring stations, a need has arisen for statistical methods suitable for the analysis of large spatial datasets observed on large spatial domains. Statistical analyses of such datasets provide two main challenges: First, traditional spatial-statistical techniques are often unable to handle large numbers of observations in a computationally feasible way. Second, for large and heterogeneous spatial domains, it is often not appropriate to assume that a process of interest is stationary over the entire domain. We address the first challenge by using a model combining a low-rank component, which allows for flexible modeling of medium-to-long-range dependence via a set of spatial basis functions, with a tapered remainder component, which allows for modeling of local dependence using a compactly supported covariance function. Addressing the second challenge, we propose two extensions to this model that result in increased flexibility: First, the model is parameterized based on a nonstationary Matern covariance, where the parameters vary smoothly across space. Second, in our fully Bayesian model, all components and parameters are considered random, including the number, locations, and shapes of the basis functions used in the low-rank component. Using simulated data and a real-world dataset of high-resolution soil measurements, we show that both extensions can result in substantial improvements over the current state-of-the-art.

The enemy of my enemy is not my friend : a theory of rebel alliance patterns in civil war
Creators: name: Moncrief, Stephen Edward
Publisher: name: University of British Columbia
Year: 2012

description: Civil wars are rarely two-player affairs. Indeed, civil wars often feature several distinct rebel organizations contesting an incumbent’s territorial control, and while it would seem efficient for these rebel groups to ally with one another against the incumbent, the opposite occurs with surprising frequency: distinct rebel groups regularly fight one another even as they fight the same incumbent. I offer a simple theory that aims to explain why insurgent groups fighting the same incumbent will ally in some instances, but not in others. I argue that when an incumbent boasts military capability sufficient to credibly threaten the elimination of the opposition, rebel groups will be more likely to ally with each other in order to avoid destruction. However, when rebel groups do not fear elimination, they are less likely to ally and more likely to fight amongst themselves, even as they continue their campaigns against the incumbent. There are two reasons that these groups will fight each other: (1) in order to decrease the number of potential bargaining partners for the incumbent or a key sector of the civilian population, and (2) to avoid being disadvantaged when it comes time to divide valuable war spoils, especially when those spoils are won by supplanting the incumbent. I demonstrate the empirical plausibility of this theory with three well-documented cases, and conclude with suggestions for future research on the topic of internecine targeting between rebel groups.

description: We present a method for simulating any non-interacting and time-periodic tight-binding Hamiltonian in Fourier space using electric circuits made of inductors and capacitors. We first map the time-periodic Hamiltonian to a Floquet Hamiltonian, which converts the time dimension into a Floquet dimension. In electric circuits, this Floquet dimension is simulated as an extra spatial dimension without any time dependency in the electrical elements. The number of replicas needed in the Floquet Hamiltonian depends on the frequency and strength of the drive. We also demonstrate that we can detect the topological edge states (including the anomalous edge states in the dynamical gap) in an electric circuit by measuring the two-point impedance between the nodes. Our method paves a simple and promising way to explore and control Floquet topological phases in electric circuits.

Flickering Buoyant Diffusion Flames in Weakly Rotatory Flows

Subjects: subject: Fluid Dynamics (physics.flu-dyn)
subject: FOS: Physical sciences

description: Flickering buoyant diffusion methane flames in weakly rotatory flows were computationally and theoretically investigated. The prominent computational finding is that the flicker frequency nonlinearly increases with the rotational intensity number R (up to 0.24), which measures the relative importance of the rotational speed compared with the methane jet speed. This finding is consistent with the previous experimental observations that flame flicker is enhanced by rotatory flows within a certain extent. Based on the vortex-dynamical understanding of flickering flames that the flame flicker is caused by the periodic shedding of buoyancy-induced toroidal vortices, we formulated a scaling theory for flickering buoyant diffusion flames in weakly rotatory flows. The theory predicts that, with respect to the flicker frequency f_0 at R=0, the increase of the flicker frequency f at nonzero R obeys the scaling relation f-f_0~R^2, which agrees very well with the present computational results. In physics, the externally rotatory flow enhances the radial pressure gradient around the flame, and the significant baroclinic effect contributes an additional source for the growth of toroidal vortices so that their periodic shedding is faster.

The friction coefficient is assumed to be vanishing within certain region. We introduce a regularization for this problem and study the limiting motion for the 1-dimensional case and a multidimensional model problem. The limiting motion is a Markov process on a projected space. We specify the generator and boundary condition of this limiting Markov process and prove the convergence.

description: Working in an Intensive Care Unit (ICU) is increasingly complex and is also physically, cognitively and emotionally demanding. Although the negative emotions of work-related stress have been well studied, the opposite perspective of work engagement might also provide valuable insight into how these emotional demands may be countered. This study focused on the work engagement of ICU professionals and explored the complex relationship between work engagement, job demands and advantageous personal resources. METHODS: This was a cross-sectional survey study among ICU professionals in a single-centre university hospital. Work engagement was measured by the Utrecht Work Engagement Scale, which included items about opinions related to the respondent's work environment. Additionally, 14 items based on the Jefferson Scale of Physician Empathy were included to measure empathic ability. A digital link to the questionnaire was sent in October 2015 to a population of 262 ICU nurses and 53 intensivists. RESULTS: The overall response rate was 61% (n=193). Work engagement was negatively related both to cognitive demands among intensivists and to emotional demands among ICU nurses. No significant relationship was found between work engagement and empathic ability; however, agreeableness, conscientiousness, and emotional stability were highly correlated with work engagement. Only the number of hours worked per week remained as a confounding factor, with a negative effect of workload on work engagement after controlling for the effect of weekly working hours. CONCLUSION: Work engagement counterbalances work-related stress reactions. The relatively high workload in ICUs, coupled with an especially heavy emotional burden, may be acknowledged as an integral part of ICU work. This workload does not affect the level of work engagement, which was high for both intensivists and nurses despite the known high job demands. Specific factors that contribute to a healthy and successful work life among ICU professionals need further exploration.

description: To understand and harness the physical mechanisms of ferroelectric Hafnium Zirconium Oxide (HZO)-based devices, there is a need for clear understanding of domain interactions, their dynamics, negative capacitance effects, and other multi-domain characteristics. These crucial attributes depend on the coupling between neighboring domains quantified by the gradient energy coefficient (g). Furthermore, HZO has unique orientation-dependent lateral multidomain configurations. To develop an in-depth understanding of multi-domain effects, there is a need for thorough analysis of g. In this work, the energetics of multidomain configurations and domain growth mechanism corresponding to lateral domain walls of HZO are analyzed and gradient energy coefficients are quantified using first-principles Density Functional Theory calculations. These results indicate that one lateral direction exhibits the following characteristics: i) DW is ultra-sharp and domain growth occurs unit-cell-by-unit-cell, ii) the value of g is negative and in the order of $10^{-12} Vm^{3}C^{-1}$, and iii) g reduces (increases) with compressive (tensile) strain. In contrast, in the other lateral direction, the following attributes are observed: i) DW is gradual and domain growth occurs in quanta of half-unit-cell, ii) g is positive and in the order of $10^{-10} Vm^{3}C^{-1}$, and iii) g increases (reduces) with compressive (tensile) strain.

description: We examine partisan differences in the behavior, communication patterns and social interactions of more than 18,000 politically-active Twitter users to produce evidence that points to changing levels of partisan engagement with the American online political landscape. Analysis of a network defined by the communication activity of these users in proximity to the 2010 midterm congressional elections reveals a highly segregated, well clustered partisan community structure. Using cluster membership as a high-fidelity (87% accuracy) proxy for political affiliation, we characterize a wide range of differences in the behavior, communication and social connectivity of left- and right-leaning Twitter users. We find that in contrast to the online political dynamics of the 2008 campaign, right-leaning Twitter users exhibit greater levels of political activity, a more tightly interconnected social structure, and a communication network topology that facilitates the rapid and broad dissemination of political information.

description: Single photon emitters in solid-state crystals have received a lot of attention as building blocks for numerous quantum technology applications. Fluorescent defects in hexagonal boron nitride (hBN) stand out due to their high luminosity and robust operation at room temperature. The identical emitter fabrication at pre-defined sites is still challenging, which hampers the integration of these defects in optical systems and electro-optical devices. Here, we demonstrate the localized fabrication of hBN emitter arrays by electron beam irradiation using a standard scanning electron microscope with deep sub-micron lateral precision. The emitters are created with a high yield and a reproducible spectrum peaking at 575 nm. Our measurements of optically detected magnetic resonance have not revealed any addressable spin states. Using density functional theory, we attribute the experimentally observed emission lines to carbon-related defects, which are activated by the electron beam. Our scalable approach provides a promising pathway for fabricating room temperature single photon emitters in integrated quantum devices.

description: Many imaging applications require increasingly bright illumination sources, motivating the replacement of conventional thermal light sources with light emitting diodes (LEDs), superluminescent diodes (SLDs) and lasers. Despite their brightness, lasers and SLDs are poorly suited for full-field imaging applications because their high spatial coherence leads to coherent artifacts known as speckle that corrupt image formation. We recently demonstrated that random lasers can be engineered to provide low spatial coherence. Here, we exploit the low spatial coherence of specifically-designed random lasers to perform speckle-free full-field imaging in the setting of significant optical scattering. We quantitatively demonstrate that images generated with random laser illumination exhibit higher resolution than images generated with spatially coherent illumination. By providing intense laser illumination without the drawback of coherent artifacts, random lasers are well suited for a host of full-field imaging applications from full-field microscopy to digital light projector systems.

description: According to the `folk knowledge', the Hartree-Fock (H-F) approximation applied to the Hubbard model becomes exact in the limit of small coupling $U$ (the smaller $|U|$, the better is the H-F approximation). In \cite{BP} Bach and Poelchau have substantiated a certain version of this assertion by providing a rigorous estimate of the difference between the true ground-state energy of the simplest version of the Hubbard model and the H-F approximation to this quantity. In this paper we extend their result in two directions: i) we relax the assumption about the strict translational invariance of the hopping matrix, ii) we prove an analogous estimate for a class of multiband Hubbard models.

Subjects: subject: Wireless Communication

subject: Engineering--Electronics and Electrical

description: The increasing demand for massive connectivity, high data rates, efficient spectrum utilization, and continuous power supply to sensors in next-generation wireless networks presents significant challenges, including bandwidth scarcity and energy constraints. To address these issues, we consider a backscatter-enabled cognitive full-duplex (FD) wireless powered communication network enhanced with intelligent reflecting surfaces (IRS) and cluster non-orthogonal multiple access (NOMA), serving as a secondary network (SN) coexisting with a primary network (PN). In this setup, SN sensors access the spectrum without interfering with PN operations and operate in FD mode to nearly double the spectrum efficiency compared to half-duplex transmission. Backscatter communication allows sensors with insufficient stored energy to transmit data without significant delays, supporting real-time applications. To enhance connectivity, mitigate deep fading effects, and provide massive connectivity, we deploy IRS and NOMA techniques. However, increasing the number of sensors raises the complexity of successive interference cancellation (SIC) in NOMA systems. To alleviate this, we employ cluster NOMA, grouping sensors into clusters to reduce SIC complexity via parallel processing. The joint optimization of hybrid access point beamforming, IRS phase shifts, which lie on a unit modulus nonconvex set, and sensor uplink power allocation, under practical constraints such as nonlinear energy harvesting, imperfect channel state information, self-interference due to FD transmission, and limited buffer capacity, results in a complex, high-dimensional, and NP-hard problem. In addition, simultaneous energy harvesting and data transmission in FD mode, together with the energy harvested in one frame that is used in subsequent frames, make the optimization problem frame dependent. To efficiently solve this ergodic problem, we propose a deep reinforcement learning framework based on the twin delayed deep deterministic policy gradient (TD3) algorithm. TD3 effectively handles high-dimensional decision variables and non-convex optimization problems inherent in this system design. Our results demonstrate that TD3 nearly doubles the system’s ergodic sum-rate compared to random allocation and achieves performance comparable to particle swarm optimization but with significantly lower computational complexity and overhead, making it more suitable for large-scale networks. In conclusion, our TD3-based framework provides a scalable and robust solution for complex wireless network architecture, maximizing performance while minimizing computational load. This work advances the state-of-the-art by offering a practical solution for dense networks in next generation networks, addressing key challenges in energy efficiency, fairness, and spectral efficiency.

description: It is shown that the formalism of quantum theory naturally incorporates the psychophysical parallelism and thereby interprets itself, if the subjective aspects are taken as equal partners alongside the objective aspects as determinants of Reality as a Whole. The inevitable interplay of the subject (observer) and the object (observed) in making up Reality is brought out succinctly through a comprehensive psychophysical interpretation which includes in its bosom the truths of many of the major interpretations proposed so far as essential ingredients. At the heart of this novel approach lies the interpretation of the complex conjugate quantities such as the conjugate wave function Ψ*(r, t), the bra vector , and the observable A etc. respectively. This brings out the psycho-physical parallelism lying hidden in the quantum mechanical formalism in a quite straightforward manner. The measurement process is shown to be a two-step process comprising objective interaction through the retarded waves and subjective observation leading to rise of knowledge through the advanced waves.

description: Since the early 2000s, technology has become a part of our daily lives, especially in education and literacy. In the face of this, researchers have examined the potential effects of reading and learning through digital devices. While much of the research has concluded that reading on a digital device could negatively affect reading comprehension and cognitive behaviours, especially in school-aged children, the scope and uses of digital reading are more complex than initially thought. Our current and future students use various forms of digital reading daily and will require even more digital skills as they enter a job market dominated by technology. Therefore, our educators must ensure we prepare our students for the digital future. This review advocates for including digital literacy practices in grade school curriculum. The evidence shows that our students need computer skills to encounter, engage with, curate, and evaluate digital resources. While researchers and curriculum makers have recognized the need for this type of education, educators have yet to implement it in classrooms fully. This review provides resources and frameworks that schools, teachers, parents, and educational digital technology designers can consider when implementing digital literacy practices into their student’s education. Careful implementation, including digital literacy practices, will prepare our students for their personal and professional futures.

description: While much has changed in the last decade in Canada regarding queer inclusion, oppressive hegemonic structures have and continue to perpetuate hetero/trans/allonormativity (the assumption that everyone experiences sexual attraction) and queerphobia in educational settings and the systems that control them. Prior research has lists of suggestions for combatting these systems and structures. Yet, progress is stagnant or even being retracted for queer rights in society and educational contexts. This study looked at how educators and policy created queer inclusion and joy through a lens of optimistic queer theory. The goal of this research was to understand better how queer joy was supported in K-12 schools, what school staff were doing to support queer joy, and why they were choosing to do so. This study looked at the questions: How do queer school staff and self-identified allies see/support queerly joyful practices in some of Calgary's public schools? Why do queer school staff and self-identified allies choose to embrace queer joy? What circumstances allow for fostering queer joy in Calgary public schools? This was captured through policy analysis of nine relevant sexual orientation and gender identity policies that impacted Alberta public school teachers while also drawing upon critical arts-based methodologies to understand better the art of six Calgary educators who upheld queer joy in their work. This research found inconsistencies between the various policies but also indicated the importance of safe spaces, allies, and quality policy to ensure that queer joy could exist in schools in Alberta, Canada.

description: We obtain a lower limit on the compactification scale of extra dimension via comparison of the branching ratio in the baryonic $Λ_b\rightarrow Λμ^+ μ^-$ decay channel recently measured by CDF collaboration and our previous theoretical study. We also use the newly available form factors calculated via light cone QCD sum rules in full theory to analyze the flavour changing neutral current process of the $Σ_b \rightarrow Σ\ell^+ \ell^-$ in universal extra dimension scenario in the presence of a single extra compact dimension. We calculate various physical quantities like branching ratio, forward-backward asymmetry, baryon polarizations and double lepton polarization asymmetries defining the decay channel under consideration. We also compare the obtained predictions with those of the standard model.

description: Diffuse optical tomography (DOT) is a severely ill-posed nonlinear inverse problem that seeks to estimate optical parameters from boundary measurements. In the Bayesian framework, the ill-posedness is diminished by incorporating {\em a priori} information of the optical parameters via the prior distribution. In case the target is sparse or sharp-edged, the common choice as the prior model are non-differentiable total variation and $\ell^1$ priors. Alternatively, one can hierarchically extend the variances of a Gaussian prior to obtain differentiable sparsity promoting priors. By doing this, the variances are treated as unknowns allowing the estimation to locate the discontinuities. In this work, we formulate hierarchical prior models for the nonlinear DOT inverse problem using exponential, standard gamma and inverse-gamma hyperpriors. Depending on the hyperprior and the hyperparameters, the hierarchical models promote different levels of sparsity and smoothness. To compute the MAP estimates, the previously proposed alternating algorithm is adapted to work with the nonlinear model. We then propose an approach based on the cumulative distribution function of the hyperpriors to select the hyperparameters. We evaluate the performance of the hyperpriors with numerical simulations and show that the hierarchical models can improve the localization, contrast and edge sharpness of the reconstructions.

description: Let G be a complex affine algebraic reductive group, and let K be a maximal compact subgroup of G. Fix elements h_1,...,h_m in K. For n greater than or equal to 0, let X (respectively, Y) be the space of equivalence classes of representations of the free group of m+n generators in G (respectively, K) such that for each i between 1 and m, the image of the i-th free generator is conjugate to h_i. These spaces are parabolic analogues of character varieties of free groups. We prove that Y is a strong deformation retraction of X. In particular, X and Y are homotopy equivalent. We also describe explicit examples relating X to relative character varieties.

description: The existence of universal soft limits for gauge-theory and gravity amplitudes has been known for a long time. The properties of the soft limits have been exploited in numerous ways; in particular for relating an n-point amplitude to an (n-1)-point amplitude by removing a soft particle. Recently, a procedure called inverse soft was developed by which "soft" particles can be systematically added to an amplitude to construct a higher-point amplitude for generic kinematics. We review this procedure and relate it to Britto-Cachazo-Feng-Witten recursion. We show that all tree-level amplitudes in gauge theory and gravity up through seven points can be constructed in this way, as well as certain classes of NMHV gauge-theory amplitudes with any number of external legs. This provides us with a systematic procedure for constructing amplitudes solely from their soft limits.

description: This qualitative single case study explores how kindergarten students construct understanding of picturebook read-alouds through idea-sharing in a dialogic classroom setting. The aim was to investigate the processes by which young children engage in the co-construction of textual meanings and develop a knowledge authority role in dialogically organized read-aloud discussions. Over seven months, weekly dialogically organized read-aloud discussions were facilitated with 20 ethnically and academically diverse kindergarten students. Data from 10 book discussions were analyzed using sociocultural discourse analysis and fine-grained conversation analysis to examine students' idea-sharing. The central research question addressed how young students construct meaning through idea-sharing during dialogically organized read aloud discussions, while sub-questions explored variations in the ideas shared, changes over time, and the functions of these shared ideas in the social construction of students' meaning-making. The findings reveal that students' idea-sharing was a complex, individualized process, where each student drew upon personal resources to construct deeply meaningful interpretations of the text. While their interpretations were highly personalized, they were also malleable and evolved in response to peers’ contributions. Analysis of language patterns within the idea-sharing indicated that the students' shared ideas changed over the length of the project. By the end of the study, students employed a greater range of resources, their verbalized ideas became lengthier, contained more reasoning words and included more textual theorizing suggesting the students were engaging increasingly complex textual understandings. Furthermore, the findings suggest three critical factors in the dialogic discussions that aided students’ meaning construction; (a) exposure to shared ideas helped highlight diverse textual ideas for students to explore, (b) unconstrained idea-sharing made visible the thinking processes students engaged in and provided a starting point to collaboratively build off of and, (c) discussions held students accountable to think deeply about the text, explain their interpretations positioning these young students as active textual interrogators. These findings underscore the importance of dialogic environments in supporting young children to become confident and reflective meaning-makers, leveraging both their own and their peers’ resources to construct robust textual understandings. Recommendations for teachers and administrators are provided.

A Hamiltonian Approach to Floating Barrier Option Pricing

description: Hamiltonian approach in quantum mechanics provides a new thinking for barrier option pricing. For proportional floating barrier step options, the option price changing process is similar to the one dimensional trapezoid potential barrier scattering problem in quantum mechanics; for floating double-barrier step options, the option price changing process is analogous to a particle moving in a finite symmetric square potential well. Using Hamiltonian methodology, the analytical expressions of pricing kernel and option price could be derived. Numerical results of option price as a function of underlying price, floating rate, interest rate and exercise price are shown, which are consistent with the results given by mathematical calculations.

description: We introduce a generalization of the Kuramoto model by explicit consideration of time-dependent parameters. The oscillators' natural frequencies and/or couplings are supposed to be influenced by external, time-dependant fields, with constant or randomly-distributed strengths. As a result, the dynamics of an external system is being imposed on top of the autonomous one, a scenario that cannot be treated adequately by previous (adiabatic) approaches. We now propose an analysis which describes faithfully the overall dynamics of the system.

On the adaptive potential of negative emotions : exploring the role of sadness and anger for goal regulation
Creators: name: Slade, Loni
Publisher: name: University of British Columbia
Year: 2012

description: Negative emotions may be an outcome of goal progress. Importantly, negative emotions may also serve as guideposts for subsequent goal regulation by flagging which goals to pursue and which goals to let go. The authors examined this hypothesis using 10-day time-sampling information from 186 adults aged 20-81 years. In line with past work, young adults progressed less on their goals and experienced more negative emotions (anger, sadness) than older adults. Importantly, daily sadness and anger seem to serve different regulatory functions. Specifically, daily sadness was associated with subsequent increases in goal contemplation and end-of-study goal disengagement and goal reengagement whereas anger was not. Findings extend previous research by pointing to the adaptive potential of negative emotions for goal regulation across the adult lifespan.
