description: We propose a single-photon-by-single-photon all-optical switch concept based on interference-localized states on lattices and their delocalization by interaction. In its 'open' operation, the switch stops single photons while allows photon pairs to pass the switch. Alternatively, in the 'closed' operation, the switch geometrically separates single-photon and two-photon states. We demonstrate the concept using a three-site Stub unit cell and the diamond chain. The systems are modeled by Bose-Hubbard Hamiltonians, and the dynamics is solved by exact diagonalization with Lindblad master equation. We discuss realization of the switch using photonic lattices with nonlinearities, superconductive qubit arrays, and ultracold atoms. We show that the switch allows arbitrary 'ON'/'OFF' contrast while achieving picosecond switching time at the single-photon switching energy with contemporary photonic materials.

description: The leading-order parton processes that produce a dilepton with large transverse momentum predict that the transverse polarization should increase with the transverse momentum for almost any choice of the quantization axis for the spin of the virtual photon. The rate of approach to complete transverse polarization depends on the choice of spin quantization axis. We propose axes that optimize that rate of approach. They are determined by the momentum of the dilepton and the direction of the jet that provides most of the balancing transverse momentum.

description: Large scale datasets created from crowdsourced labels or openly available data have become crucial to provide training data for large scale learning algorithms. While these datasets are easier to acquire, the data are frequently noisy and unreliable, which is motivating research on weakly supervised learning techniques. In this paper we propose original ideas that help us to leverage such datasets in the context of change detection. First, we propose the guided anisotropic diffusion (GAD) algorithm, which improves semantic segmentation results using the input images as guides to perform edge preserving filtering. We then show its potential in two weakly-supervised learning strategies tailored for change detection. The first strategy is an iterative learning method that combines model optimisation and data cleansing using GAD to extract the useful information from a large scale change detection dataset generated from open vector data. The second one incorporates GAD within a novel spatial attention layer that increases the accuracy of weakly supervised networks trained to perform pixel-level predictions from image-level labels. Improvements with respect to state-of-the-art are demonstrated on 4 different public datasets.

title: Structural drivers of sustainability and resilience strategies in small(ish) cities: a text analysis of comprehensive planning in Indiana
Creators: name: Deslatte, Aaron

Year: 2023

description: For decades, the world?s largest and most globally significant cities have been pledging to tackle climate change, resilience, sustainable development and social injustices through a proliferating ecology of plans. Far less is understood about what is happening in smaller communities. This study employs an institutional lens and automated text analysis to examine the resilience and sustainability ?shared strategies? embedded in local land-use plans, which are used in many countries to guide the spatial distribution of development in metropolitan regions. We find evidence that communities that are more highly educated and less racially diverse focus more on ?quality of life? amenities within their plans, such as pedestrian resources and environmental amenities. By contrast, communities that are more racially diverse focus greater attention on green stormwater infrastructure to address flooding. Plan ?quality? is negatively associated with an amenities? focus. Taken together, these findings suggest comprehensive land-use planning is both a means for reflecting exclusivity as well as pursuing community needs or goals related to specific resilience or sustainability themes.

Antics : a system for animating LISP programs
Creators: name: Dionne, Mark Stephen
Publisher: name: University of British Columbia
Year: 2010

description: An animated film is an excellent medium for conveying complex ideas in computer science. A system has been developed which produces animated films, film strips, or slides depicting the execution of LISP programs. The design and implementation of this system is discussed and it is compared to existing systems. The system, named ANTICS, may be used by entering very simple commands, and produces real-time animation. The system may be "backed up" interactively and atomic values may be changed. Advanced commands and a set of graphics primitives are available which permit an instructor or film-maker to control minute details of the animation and to add features not explicitly provided by the system. ANTICS may therefore be used as an interactive educational tool or as an animation system. ANTICS is very economical to use. A three minute film showing the operation of the recursive function MEMBER was produced for a total cost of $12.00. The film is included as part of the thesis. The system is dependent on IBM 370/168 and Adage Graphics Terminal hardware, but the design, which is based on the organization of the LISP EVAL function, could be used on other systems.
Growth of the MRI in Accretion Discs -- the Influence of Radiation Transport

description: In this paper we investigate the influence of radiative transport on the growth of the magnetorotational instability (MRI) in accretion discs. The analysis is performed by use of analytical and numerical means. We provide a general dispersion relation together with the corresponding eigenfunctions describing the growth rates of small disturbances on a homogeneous background shear flow. The dispersion relation includes compressibility and radiative effects in the flux-limited diffusion approximation. By introducing an effective speed of sound, all the effects of radiation transport can be subsumed into one single parameter. It can be shown that the growth rates of the vertical modes -- which are the fastest growing ones -- are reduced by radiative transport. For the case of non-vertical modes, the growth rates may instead be enhanced. We quantify the effects of compressibility and radiative diffusion on the growth rates for the gas-pressure dominated case. The analytical discussion is supplemented by numerical simulations, which are also used for a first investigation of the non-linear stage of the MRI in gas-pressure dominated accretion discs with radiation transport included.

description: Pulsar Timing Arrays (PTAs) are expected to be able to detect gravitational waves (GWs) from individual supermassive black hole binaries in the near future. In order to identify the host galaxy of a gravitational wave source, the angular resolution of PTAs should be much better than that expected from the conventional methodology of PTAs. We study the potential usefulness of precise pulsar-distance measurements in the determination of the sky location of a single GW source. Precise distance information from external observations such as astrometry by Very Long Baseline Interferometry is incorporated as priors in the PTA analysis and we evaluate the precision of the sky location of a GW source by simulating PTA data of 12 milli-second pulsars with only the GW signal and the Gaussian white noise in the timing residuals. We show that only a few pulsars with a distance precision of 1 pc will improve the precision of the source location by more than 1 order in the presence of white noise of 10 ns.

Data from: Niche conservatism over deep timescales and diverse niche axes in land vertebrates
Creators: name: Saban, Kristen
name: Qu, Yan-Fu
name: Wiens, John
Publisher: name: Zenodo
Year: 2023

description: Aim: There has been considerable interest in niche conservatism, the idea that ecological variables are similar among related species. Much research has focused on climatic niches of recently diverged species, rather than deeper timescales or non-climatic niche axes. Furthermore, it has been suggested that conservatism disappears over deeper timescales, and is greater in alpha niche traits (like diet and microhabitat) than beta niche variables (like climate). Here, we test these two ideas by comparing patterns of phylogenetic conservatism among 10 niche variables across major clades of land vertebrates. Location: Global. Time period: Present to 350 million years ago. Major taxa studied: Tetrapods, including amphibians, mammals, lepidosaurs (including lizards and snakes), turtles, crocodilians, and birds. Methods: The 10 niche variables included four alpha niche components (diet, diel activity, habitat, body temperature) and six beta niche components (related to climatic temperature and precipitation). We analyzed these variables on time-calibrated phylogenies with similar taxon sampling (~1700 species), using phylogenetic signal (lambda) to estimate conservatism, along with the D-statistic and estimates of evolutionary rates. Results: Phylogenetic signal was generally strong across all variables, with lambda generally >0.80 (with 1.0 representing maximum signal). Nevertheless, mean phylogenetic signal was lower in beta niche traits than alpha niche traits (based on lambda and especially the D-statistic), and alpha niche traits showed significantly slower rates of evolution. Main conclusions: We address two long-held views in the literature on niche conservatism, rejecting one but supporting the other. We show that phylogenetic signal does not disappear over deep timescales for many important niche variables, even over 350 million years. We also generally support greater conservatism in alpha niche traits than beta niche traits over hundreds over millions of years, a pattern that was previously suggested (but not explicitly tested) based on closely related species.

description: We used Suzaku observations of the molecular cloud MBM20 and a low neutral hydrogen column density region nearby to separate and characterize the foreground and background diffuse X-ray emission. A comparison with a previous observation of the same regions with XMM-Newton indicates a significant change in the foreground flux which is attributed to Solar Wind Charge eXchange (SWCX). The data have also been compared with previous results from similar "shadow" experiments and with a SWCX model to characterize its O VII and O VIII emission.

description: The problem of Dirac fermions in graphite subject to a perpendicular magnetic field is studied. We show analytically that the weak inter-layer interaction between the graphene sheets leads to anomalies in the Shubnikov-de Haas and de Haas-van Alphen magneto-oscillations governed by the orbits around extremal cross-sections of the graphite Fermi surface. The calculation of the Landau plot performed within a four band continuum model reveals that magneto-oscillations are aperiodic, except of the case of vanishing inter-layer interaction at the H point of the graphite Brillouin zone. Also for all other orbits along the H-K-H edge the magneto-oscillations are only asymptotically periodic in the quasi-classical limit, with the phase corresponding to massive fermions.

description: Caesium fountain frequency-standards realize the second in the International System of Units with a relative uncertainty approaching 10^-16. Among the main contributions to the accuracy budget, cold collisions play an important role because of the atomic density shift of the reference atomic transition. This paper describes an application of the Bayesian analysis of the clock frequency to estimate the density shift and describes how the Bayes theorem allows the a priori knowledge of the sign of the collisional coefficient to be rigourously embedded into the analysis. As an application, data from the INRIM caesium fountain are used and the Bayesian and orthodox analyses are compared. The Bayes theorem allows the orthodox uncertainty to be reduced by 28% and demonstrates to be an important tool in primary frequency-metrology.

description: Consider a family of infinite tri--diagonal matrices of the form $L+ zB,$ where the matrix $L$ is diagonal with entries $L_{kk}= k^2,$ and the matrix $B$ is off--diagonal, with nonzero entries $B_{k,{k+1}}=B_{{k+1},k}= k^α, 0 \leq α< 2.$ The spectrum of $L+ zB$ is discrete. For small $|z|$ the $n$-th eigenvalue $E_n (z), E_n (0) = n^2,$ is a well--defined analytic function. Let $R_n$ be the convergence radius of its Taylor's series about $z= 0.$ It is proved that $$ R_n \leq C(α) n^{2-α} \quad \text{if} 0 \leq α<11/6.$$

We apply it to the collapse of carbon nanotubes, the formation of bottlenecks in nanowires, both of which limit conductance, and the opening of local regions or "bubbles" of base pairs in strands of DNA that are relevant for transcription and danaturation. We predict an exponential behavior for the probability of the opening of bubbles in DNA, the average distance between flattened regions of a nanotube or necking in a nanowire as a monotonically decreasing function of temperature, and compute a temperature below which these events become extremely rare. These findings are difficult to obtain numerically, however, they could be accessible experimentally.

The Spread of AI-Generated Misinformation

Publisher: name: Maher Asaad Baker - SOLAV
Year: 2023

description: In today's digital world, information flows freely and endlessly across borders and platforms. While this connectivity has empowered the spread of ideas, it has also enabled the propagation of misleading claims that can erode truth and trust. A new threat has emerged from the rising tide of artificial intelligence, as generative models allow the industrial-scale production of synthetic yet sophisticated content. Like a flood, AI-generated misinformation and disinformation threaten to drown the foundations of an informed society under a deluge of falsity. We must acknowledge that this flood was not unforeseen, but the inevitable result of careless development and deployment without adequate responsibility or wisdom. The creators of these powerful tools failed to consider their darker applications and the need to establish guardrails against abuse. Now the waters rage largely unchecked, with platforms struggling to stem the current and individuals left floundering in murky confusion. While regulation and moderation have roles, the solution lies deeper - in taking ownership of our technological progress and prioritizing integrity over expediency. The tide will not recede through reaction alone but requires a turn toward proactive responsibility. Developers must recognize their ethical duty to envision misuse and implement safeguards that do not compromise functionality but uphold reliability. Platforms must find transparency and educate users to bolster critical thinking against manipulation. Individuals too have a part, in media literacy and willingness to reconsider preconceptions in the face of contradictory evidence. We must shore up our foundations with truth and wisdom before the coming storm. This thesis aims to survey the rising floodwaters and assess our defenses. It will define the concepts of misinformation and disinformation, differentiating falsehood by intent. It will examine how generative AI enables the mass production of synthetic content, from deepfakes to persuasive text, and the realistic yet misleading material this facilitates. Detection methods will be explored, considering techniques from fact-checking to provenance analysis. Platform policies and individual responsibilities will also be evaluated. Through rigorous analysis this work seeks to bring clarity and responsibility to the issue. It aims to neither deny technological progress nor dismiss risk, but navigate a balanced path between the two. Ultimately it calls us to rise above reaction and embrace foresight, prioritizing integrity over convenience in both creation and consumption of information. The tide of falsity grows swiftly, but with wisdom and courage, we can establish bulwarks of truth to withstand the coming flood. By understanding the challenges and cooperating constructively, our society can emerge from this trial with foundations reinforced rather than eroded. The time to prepare is now, before the deluge.

description: For the paradigmatic three-disk scattering system, we confirm a recent conjecture for open chaotic systems, which claims that resonance states are composed of two factors. In particular, we demonstrate that one factor is given by universal exponentially distributed intensity fluctuations. The other factor, supposed to be a classical density depending on the lifetime of the resonance state, is found to be very well described by a classical construction. Furthermore, ray-segment scars, recently observed in dielectric cavities, dominate every resonance state at small wavelengths also in the three-disk scattering system. We introduce a new numerical method for computing resonances, which allows for going much further into the semiclassical limit. As a consequence we are able to confirm the fractal Weyl law over a correspondingly large range.

Publisher: name: Sage
Year: 2010

description: Concerns about low motivation to change among perpetrators of intimate partner violence (IPV) have heightened interest employing behavior change models with this population. In the present investigation, a new scale was developed, the Outcome Expectancies for Partner Abuse (OEPA) Scale, assessing the negative and positive outcome expectancies of partner abuse. Items were generated from statements made by IPV offenders during videotaped group therapy sessions. Among a clinical sample of 130 IPV perpetrators, item psychometric properties, factor structure, and subscale validity were examined. Results indicated generally good psychometric properties and a 2-factor solution, with the exception of 4 items subsequently removed from the negative expectancies scale. Significant associations were demonstrated between instrument subscales, readiness to change, and self-reported abusive behavior. Additionally, positive expectancy scores correlated with anger problems and relationship adjustment whereas negative expectancy scores correlated with partner-reported IPV. Potential uses of the OEPA and future directions for psychometric research are discussed.

Emerging Multiprocessor System-on-Chip (MPSoC) platforms along with comprehensive support for virtualization will represent two key building blocks for smart devices in future IIoT edge infrastructures. We review representative existing solutions, highlighting the aspects that are most relevant for integration in IIoT solutions. From the analysis, we derive a reference architecture for a general virtualization-ready edge IIoT node. We then analyze the implications and benefits for a concrete use case scenario and identify the crucial research challenges to be faced to bridge the gap towards full support for virtualization-ready IIoT nodes

description: Within the asymptotic safety program, it is possible to construct renormalization group (RG) improved spacetimes by replacing the gravitational coupling $G$ by its running counterpart $G(k)$, and subsequently identifying the RG scale $k$ with a physical distance scale. This procedure has been used to construct a regular Schwarzschild geometry, but it fails in the presence of a cosmological constant. This can only be avoided if the dimensionless cosmological constant has a trivial ultraviolet fixed point, but so far no such scenario has been encountered in quantum general relativity (with or without matter). In this Letter we provide a possible solution to this problem. In Poincare gauge gravity an effective cosmological constant arises naturally, and if the non-Abelian Lorentz spin connection is asymptotically free, it generates a trivial ultraviolet fixed point for this cosmological constant. We thereby tentatively propose a nonsingular black hole consistent with the principles of asymptotic safety, embedded in Poincare gauge gravity.

Subjects: subject: Mathematical Physics (math-ph)

description: We present a method to study phase transitions in the large N limit of matrix models using matched solutions of Whitham hierarchies. The endpoints of the eigenvalue spectrum as functions of the temperature are characterized both as solutions of hodograph equations and as solutions of a system of ordinary differential equations. In particular we show that the free energy of the matrix model is the quasiclassical tau-function of the associated hierarchy, and that critical processes in which the number of cuts changes in one unit are third-order phase transitions described by C1 matched solutions of Whitham hierarchies. The method is illustrated with the Bleher-Eynard model for the merging of two cuts. We show that this model involves also a birth of a cut.

description: Despite widespread kratom use, there is a lack of knowledge regarding its effects on driving. We evaluated the self-reported driving behaviors of kratom consumers and assessed their simulated-driving performance after self-administering kratom products. We present results from: 1) a remote, national study of US adults who regularly use kratom, and 2) an in-person substudy from which we re-recruited participants. In the national study (N = 357), participants completed a detailed survey and a 15-day ecological momentary assessment (EMA) that monitored naturalistic kratom use. For the remote study, outcomes were self-reported general and risky driving behaviors, perceived impairment, and driving confidence following kratom administration. For the in-person substudy, 10 adults consumed their typical kratom products and their driving performance on a high-fidelity driving simulator pre- and post-kratom administration was evaluated. Over 90% of participants surveyed self-reported driving under the influence of kratom. Most reported low rates of risky driving behavior and expressed high confidence in their driving ability after taking kratom. This was consistent with EMA findings: participants reported feeling confident in their driving ability and perceived little impairment within 15-180 min after using kratom. In the in-person substudy, there were no significant changes in simulated driving performance after taking kratom. Using kratom before driving appears routine, however, self-reported and simulated driving findings suggest kratom effects at self-selected doses among regular kratom consumers do not produce significant changes in subjective and objective measures of driving impairment. Research is needed to objectively characterize kratom?s impact on driving in regular and infrequent consumers.
Of caterpillars and models

Publisher: name: University of British Columbia

description: An approach to modeling in general, its background, and its implementation can be described by examining its application to a particular system. The Western Tent Caterpillar is a productive subject of study because there is extensive data available for determining the relationships within the system. Individual differences between caterpillars and the weather are the dominant factors involved. They are incorporated into a set of ordinary differential equations that express the rate of change in the caterpillar population over time. These equations are numerically integrated to calculate the population at some terminal time. The results over a six year period agree reasonably well with observed field data. The three dimensional plot of the population gives a visual appreciation for the distribution over time.

description: The formation of planetesimals is expected to occur via particle-gas instabilities that concentrate dust into self-gravitating clumps. Triggering these instabilities requires the prior pileup of dust in the protoplanetary disk. Until now, this has been successfully modeled exclusively at the disk's snowline, whereas rocky planetesimals in the inner disk were obtained only by assuming either unrealistically large particle sizes or an enhanced global disk metallicity. However, planetesimal formation solely at the snowline is difficult to reconcile with the early and contemporaneous formation of iron meteorite parent bodies with distinct oxidation states and isotopic compositions, indicating formation at different radial locations in the disk. Here, by modeling the evolution of a disk with ongoing accretion of material from the collapsing molecular cloud, we show that planetesimal formation may have been triggered within the first 0.5 million years by dust pileup at both the snowline (at approximately 5 au) and the silicate sublimation line (at approximately 1 au), provided turbulent diffusion was low. Particle concentration at approximately 1 au is due to the early outward radial motion of gas and is assisted by the sublimation and recondensation of silicates. Our results indicate that, although the planetesimals at the two locations formed about contemporaneously, those at the snowline accreted a large fraction of their mass (approximately 60 percent) from materials delivered to the disk in the first few 10,000 yr, whereas this fraction is only 30 percent for the planetesimals formed at the silicate line. Thus, provided that the isotopic composition of the delivered material changed with time, these two planetesimal populations should have distinct isotopic compositions, consistent with observations.

description: This paper deals with the delay-throughput analysis of a single-hop wireless network with $n$ transmitter/receiver pairs. All channels are assumed to be block Rayleigh fading with shadowing, described by parameters $(α,\varpi)$, where $α$ denotes the probability of shadowing and $\varpi$ represents the average cross-link gains. The analysis relies on the distributed on-off power allocation strategy (i.e., links with a direct channel gain above a certain threshold transmit at full power and the rest remain silent) for the deterministic and stochastic packet arrival processes. It is also assumed that each transmitter has a buffer size of one packet and dropping occurs once a packet arrives in the buffer while the previous packet has not been served. In the first part of the paper, we define a new notion of performance in the network, called effective throughput, which captures the effect of arrival process in the network throughput, and maximize it for different cases of packet arrival process. It is proved that the effective throughput of the network asymptotically scales as $\frac{\log n}{\hatα}$, with $\hatα \triangleq α\varpi$, regardless of the packet arrival process. In the second part of the paper, we present the delay characteristics of the underlying network in terms of the packet dropping probability. We derive the sufficient conditions in the asymptotic case of $n \to \infty$ such that the packet dropping probability tend to zero, while achieving the maximum effective throughput of the network. Finally, we study the trade-off between the effective throughput, delay, and packet dropping probability of the network for different packet arrival processes.

description: When neglecting capillarity, two-phase incompressible flow in porous media is modelled as a scalar nonlinear hyperbolic conservation law. A change in the rock type results in a change of the flux function. Discretizing in one-dimensional with a finite volume method, we investigate two numerical fluxes, an extension of the Godunov flux and the upstream mobility flux, the latter being widely used in hydrogeology and petroleum engineering. Then, in the case of a changing rock type, one can give examples when the upstream mobility flux does not give the right answer.

description: We consider bulk correlation numbers on disk in one-matrix model. Using the recently found so-called resonance transformation from the KdV to the Liouville frame, we obtain an explicit expression for the bulk one-point function. The result is consistent with the form of FZZ one-point function in the boundary Liouville Field Theory.

description: In 1981 Durhuus and Olesen (DO) showed that at infinite N the eigenvalue density of a Wilson loop matrix W associated with a simple loop in two-dimensional Euclidean SU(N) Yang-Mills theory undergoes a phase transition at a critical size. The averages of det(z-W), 1/det(z-W), and det(1+uW)/(1-vW) at finite N lead to three different smoothed out expressions, all tending to the DO singular result at infinite N. These smooth extensions are obtained and compared to each other.

subject: differential outcomes

description: Our behavioral units include stimulus classes and response classes. Peter Urcuioli?s differential-outcomes research implies they should extend to the third term of the three-term contingency. Classes of consequences come in several varieties (e.g., conditional reinforcers, tokens), but our vocabulary does not coherently organize them. They are differentiated not only by physical properties such as type, location and duration but also by the schedule contingencies in which they participate. We consider units ranging from the physical and chemical sciences to those based on the particular history of life on earth. The latter include biology, sociology, linguistics, and our own behavior analysis. Scientific units are typically nested (e.g., atoms within molecules; cells within organs; organisms within species). Comparing our units with those from other taxonomies raises questions about their emergence and evolution and their shared properties across levels of nesting (e.g., species within genus; subclasses within higher-order operants; phonemes within words). Emergence necessarily occurs when higher-order units have functions not shared with their lower-order constituents. These nested and multi-leveled behavior classes challenge single-level views, such as metaphorical accounts of behavior as a totality contained within a pie with slices corresponding to behavior classes matched to their outcomes.

description: We investigate the dynamics of a quantum system subjected to a time-dependent and conditional resetting protocol. Namely, we ask: what happens when the unitary evolution of the system is repeatedly interrupted at random time instants with an instantaneous reset to a specified set of reset configurations taking place with a probability that depends on the current configuration of the system at the instant of reset? Analyzing the protocol in the framework of the so-called tight-binding model describing the hopping of a quantum particle to nearest-neighbour sites in a one-dimensional open lattice, we obtain analytical results for the probability of finding the particle on the different sites of the lattice. We explore a variety of dynamical scenarios, including the one in which the resetting time intervals are sampled from an exponential as well as from a power-law distribution, and a set-up that includes a Floquet-type Hamiltonian involving an external periodic forcing. Under exponential resetting, and in both presence and absence of the external forcing, the system relaxes to a stationary state characterized by localization of the particle around the reset sites. The choice of the reset sites plays a defining role in dictating the relative probability of finding the particle at the reset sites as well as in determining the overall spatial profile of the site-occupation probability. Indeed, a simple choice can be engineered that makes the spatial profile highly asymmetric even when the bare dynamics does not involve the effect of any bias. Furthermore, analyzing the case of power-law resetting serves to demonstrate that the attainment of the stationary state in this quantum problem is not always evident and depends crucially on whether the distribution of reset time intervals has a finite or an infinite mean.

An expressive language
Creators: name: Whaley, Paul William
Publisher: name: University of British Columbia
Year: 2010

description: A programming language system which enables a programmer to create his own constructs for the description of an algorithm is presented. The syntactic and semantic design and some details of the implementation are discussed and the language itself is described. For the introduction of new constructs by the programmer, the language system (called "Tove") provides a parsing language for syntactic description and a set of basic procedures for semantic description. The combination of these two enable the programmer to define new procedures, control structures, and operators. Finally, some problems in the design and implementation are discussed,
