A signal-flow model for the design of social biofeedback systems
Creators: name: McCaig, Ronald Graeme
Publisher: name: University of British Columbia
Year: 2010

description: This paper explores the design of ’social biofeedback systems’ (SBFS’s) by presenting a theoretical ’signal-flow model’ and a particular system design called 2Hearts. A proposed definition is given of SBFS’s as systems which sense and display biosensor-derived data in real-time, involve multiple people in social-communication, and convey information relative to emotion or affect. Previous SBFS systems and other related works are reviewed to show both the pattern of interest in such systems and the lack of an underlying theoretical framework. The signal-flow model is developed in detail with reference to literature from psychology, auditory display and affective computing; in its current form the model is focused on SBFS’s which employ heart-sensor data as input and audio as output. Key features of the model are a distinction between conscious and unconscious perception/processing of emotional information, and identification of several different representations of affect information within the brain that are useful for SBFS’s to replicate or process. Suggested design tools are described including SBFS design-goal ’paradigms’ and a high-level SBFS design procedure, framed in terms of the signal-flow model. The design and implementation of the 2Hearts system is described and justified according to the signal-flow model. The 2Hearts system incorporates time-compression/looping techniques to display different heart-data-derived variables in a synchronized, layered fashion, leading to the perception of rhythmic, musical audio patterns. The design and results of 2Hearts user testing are described. Significant testing results are obtained which characterize the emotional associations of some of the 2Hearts audio-display mappings, and lead to suggestions for improvement of these mappings. Other significant results suggest that people can voluntarily influence each others’ heart rates using communicative strategies, thus validating one important assumption of SBFS design. Recommendations are given for future development of the 2Hearts system, the signal-flow model, and the user testing strategies.

description: We consider the problem of optimising the achievable EPR-pair distribution rate between multiple source-destination pairs in a quantum internet, where the repeaters may perform a probabilistic bell-state measurement and we may impose a minimum end-to-end fidelity as a requirement. We construct an efficient linear programming formulation that computes the maximum total achievable entanglement distribution rate, satisfying the end-to-end fidelity constraint in polynomial time (in the number of nodes in the network). We also propose an efficient algorithm that takes the output of the linear programming solver as an input and runs in polynomial time (in the number of nodes) to produce the set of paths to be used to achieve the entanglement distribution rate. Moreover, we point out a practical entanglement generation protocol which can achieve those rates.

description: We present numerical evidence that suggests the introduction of a non-zero pion mass might dramatically affect the structure of minimal energy Skyrmions. It appears that the shell-like Skyrmions which are the minima when the pions are massless can fail to be minimal energy bound states for particular baryon numbers, with a strong dependence upon the value of the pion mass. The effects of a pion mass may include the replacement of shell-like configurations with crystal chunks and the loss of shell-like bound states with baryon numbers five and eight; which is in agreement with expectations based on real nuclei.

description: Heterogeneous sonochemical method was applied for synthesis of novel superconducting nanocomposites consisting of magnetic (and/or nonmagnetic) nanoparticles embedded into the bulk of ceramic superconductors. In addition to in-situ production of the efficient pinning centers, this synthesis method considerably improves the interbrain coupling. Significant enhancement of the magnetic irreversibility is reported for Fe2O3 nanoparticles embedded into the bulk of MgB2 superconductor. Nonmagnetic Mo2O5 nanoparticles also increase pinning strength, but less than magnetic Fe2O3. Detailed magnetization and electron microscopy characterization is presented. Theory of bulk magnetic pinning due to ferromagnetic nanoparticles of finite size embedded into the superconducting matrix is developed.

description: We propose a redefinition of the principal component analysis (PCA) of anisotropic flow that makes it more directly connected to fluctuations of the initial geometry of the system. Then, using state-of-the-art hydrodynamic simulations, we make an explicit connection between flow fluctuations and a cumulant expansion of the initial transverse geometry. In particular, we show that the second principal component of elliptic flow is generated by higher-order cumulants, and therefore probes smaller length scales of the initial state. With this information, it will be possible to put new constraints on properties of the early-time dynamics of a heavy-ion collision, including small-scale structure, as well as properties of the quark-gluon plasma.

description: Nuclear-structure effects often provide an irreducible theory error that prevents using precision atomic measurements to test fundamental theory. We apply newly developed effective field theory tools to Hydrogen atoms, and use them to show that (to the accuracy of present measurements) all nuclear finite-size effects (e.g. the charge radius, Friar moments, nuclear polarizabilities, recoil corrections, Zemach moments {\it etc.}) only enter into atomic energies through exactly two parameters, independent of any nuclear-modelling uncertainties. Since precise measurements are available for more than two atomic levels in Hydrogen, this observation allows the use of precision atomic measurements to eliminate the theory error associated with nuclear matrix elements. We apply this reasoning to the seven atomic measurements whose experimental accuracy is smaller than 10 kHz to provide predictions for nuclear-size effects whose theoretical accuracy is not subject to nuclear-modelling uncertainties and so are much smaller than 1 kHz. Furthermore, the accuracy of these predictions can improve as atomic measurements improve, allowing precision fundamental tests to become possible well below the 'irreducible' error floor of nuclear theory.

Beyond Time I: A Proposal to Reframe the Role of Light-Speed as the Foundational Boundary of Perceived Temporality
Creators: name: Yildirim, Kubilay
Publisher: name: Zenodo
Year: 2025

description: Abstract

This paper proposes a conceptual shift in our understanding of time: rather than being a fundamental dimension of the universe, time may be an emergent property arising from the light-speed boundary condition. The hypothesis posits that only objects moving below the speed of light experience sequential change—what we interpret as time—while massless particles moving at c experience none. Drawing from relativity, quantum gravity, and philosophical interpretations, this perspective challenges conventional spacetime frameworks and invites a reconsideration of time’s ontological status in physics.

description: A Boolean function of n bits is balanced if it takes the value 1 with probability 1/2. We exhibit a balanced Boolean function with a randomized evaluation procedure (with probability 0 of making a mistake) so that on uniformly random inputs, no input bit is read with probability more than Theta(n^{-1/2} sqrt{log n}). We give a balanced monotone Boolean function for which the corresponding probability is Theta(n^{-1/3} log n). We then show that for any randomized algorithm for evaluating a balanced Boolean function, when the input bits are uniformly random, there is some input bit that is read with probability at least Theta(n^{-1/2}). For balanced monotone Boolean functions, there is some input bit that is read with probability at least Theta(n^{-1/3}).

description: We analyze the Wheeler-DeWitt (WDW) equation in the context of a gravitational collapse. The physics of an expanding/collapsing universe and many details of a collapsing star can classically be described by the Roberston-Walker metric in which the WDW equation takes the form of a times-less Schrödinger equation. We set up the corresponding WDW potential for the collapse and study the solutions of the wave function. The results show that the central singularity appearing in classical general relativity is avoided, the density is quantized in terms of the Planck density and the expectation value of the scale factor exhibits a discrete behavior.

description: Heterogeneous sonochemical synthesis was used to modify superconducting properties of granular YBa2Ca3CuO7-y and Bi2Sr2CaCu2O8+x. Sonication of liquid-powder alkane slurries produces material with enhanced intergrain coupling and improved current-carrying capabilities. Co-sonication with metals and organometallics results in highly compact nanocomposites with increased magnetic irreversibility. Ultrasonic irradiation of YBa2Ca3CuO7-y carried under partial oxygen atmosphere produces similar morphological effects and increases superconducting transition temperature due to effective surface saturation with oxygen. Detailed chemical and physical characterization of sonochemically prepared high-Tc nanocomposites is presented.

description: We study analytically a gravitational lens due to a deformed star, which is modeled by using a monopole and a quadrupole moment. Positions of the images are discussed for a source on the principal axis. We present explicit expressions for the lens equation for this gravitational lens as a single real tenth-order algebraic equation. Furthermore, we compute an expression for the caustics as a discriminant for the polynomial. Another simple parametric representation of the caustics is also presented in a more tractable form. A simple expression for the critical curves is obtained to clarify a topological feature of the critical curves; the curves are simply connected if and only if the distortion is sufficiently large.

description: We present new ALMA Band 6 observations including the CO(2-1) line and 1.3 mm continuum emission from the surroundings of the young stellar object DO Tauri. The ALMA CO molecular data show three different series of rings at different radial velocities. These rings have radii around 220 au and 800 au. We make individual fits to the rings and note that their centers are aligned with DO Tauri and its optical high-velocity jet. In addition, we notice that the velocity of these structures increases with the separation from the young star. We discuss the data under the hypothesis that the rings represent velocity cuts through three outflowing shells that are possibly driven by a wide-angle wind, dragging the environment material along a direction close to the line of sight (i=19°). We estimate the dynamical ages, the mass, the momentum and the energy of each individual outflow shell and those of the whole outflow. The results are in agreement with those found in outflows from Class II sources. We make a rough estimate for the size of the jet/wind launching region, which needs to be of <15 au. We report the physical characteristics of DO Tauri's disk continuum emission (almost face-on and with a projected major axis in the north-south direction) and its velocity gradient orientation (north-south), indicative of disk rotation for a 1-2 Msun central star. Finally we show an HST [SII] image of the optical jet and report a measurement of its orientation in the plane of the sky.

description: This work examined the existence of plural forms in the transaction between slaughterhouses and beef cattle farmers, analyzing the determinants of companies’ choice of governance structures. Three slaughterhouses were studied, using the literature of plural forms of governance as theoretical framework. It was found that only one of the slaughterhouses adopts plural forms to coordinate their beef cattle purchase transactions, and the other two companies obtained all of their live cattle supply through spot market trades. The determinants of plural forms adoption were aligned with the theoretical model. Ambiguity, complexity and strategic behavior variables determine the choice of the governance structure. For the other two companies, we noted little or no ambiguity and complexity in the transactions, and the absence of strategic motivations for the use of plural forms. Principal advantages of this strategy of coordination were: (i) reduction of information asymmetry; (ii) advantages of scale and greater bargaining power in the spot market; (iii) flexibility to supply different distribution channels and (iv) cross-learning effects.

description: Boulders form from a variety of geological processes, which their size, shape, and orientation may help us better understand. Furthermore, they represent potential hazards to spacecraft landing that need to be characterized. However, mapping individual boulders across vast areas is extremely labor-intensive, often limiting the extent over which they are characterized and the statistical robustness of obtained boulder morphometrics. To automate boulder characterization, we use an instance segmentation neural network, Mask R-CNN, to detect and outline boulders in high-resolution satellite images. Our neural network, BoulderNet, was trained from a dataset of > 33,000 boulders in > 750 image tiles from Earth, the Moon, and Mars. BoulderNet not only correctly detects the majority of boulders in images, but it identifies the outline of boulders with high fidelity, achieving average precision and recall values of 72% and 64% relative to manually digitized boulders from the test dataset, when only detections with intersection-over-union ratios > 50% are considered valid. These values are similar to those obtained by human mappers. On Earth, equivalent boulder diameters, aspect ratios, and orientations extracted from predictions were benchmarked against ground measurements and yield values within 15%, 0.20, and 20 degrees of their ground-truth values, respectively. BoulderNet achieves better boulder detection and characterization performance relative to existing methods, providing a versatile open-source tool to characterize entire boulder fields on planetary surfaces.

Subjects: subject: Software Engineering (cs.SE)

description: To make microtask programming more efficient and reduce the potential for conflicts between contributors, I developed a new behavior-driven approach to microtasking programming. In our approach, each microtask asks developers to identify a behavior behavior from a high-level description of a function, implement a unit test for it, implement the behavior, and debug it. It enables developers to work on functions in isolation through high-level function descriptions and stubs. In addition, I developed the first approach for building microservices through microtasks. Building microservices through microtasks is a good match because our approach requires a client to first specify the functionality the crowd will create through an API. This API can then take the form of a microservice description. A traditional project may ask a crowd to implement a new microservice by simply describing the desired behavior in a API and recruiting a crowd. We implemented our approach in a web-based IDE, \textit{Crowd Microservices}. It includes an editor for clients to describe the system requirements through endpoint descriptions as well as a web-based programming environment where crowd workers can identify, test, implement, and debug behaviors. The system automatically creates, manages, assigns microtasks. After the crowd finishes, the system automatically deploys the microservice to a hosting site.

description: The implications of seven popular models of quintessence based on supergravity or M/string theory for the transition from a decelerating to an accelerating universe are explored. All seven potentials can mimic the LambdaCDM model at low redshifts 0 < z < 5. However, for a natural range of initial values of the quintessence field, the SUGRA and Polonyi potentials predict a transition redshift z_t = 0.5 for Omega_Lambda0 = 0.70, in agreement with the observational value z_t = 0.46 and in mild conflict with the LambdaCDM value z_t = 0.67. Tables are given for the quintessence potentials for the recent average wbar_0 of the equation of state parameter, and for w_0 and w_1 in the low-z approximation w = w_0 + w_1 z. It is argued that for the exponential potential e^{lambda phi} to produce a viable present-day cosmology, lambda <= sqrt{2}. A robust, scaled numerical method is presented for simulating the cosmological evolution of the scalar field.

Carbon nanotube and polypyrrole supercapacitors
Creators: name: Izadi-Najafabadi, Ali
Publisher: name: University of British Columbia
Year: 2010

description: Supercapacitors are electrochemical devices intended to combine the high power density of conventional capacitors with the high energy density of batteries. They can store energy electrostatically at the interface between a metal electrode and an electrolyte (double layer capacitance) and/or Faradaic energy storage through reversible successive redox processes (pseudocapacitance). The amount of accessible surface area of the electrode to the electrolyte and the amount of time required for electronic charges and ionic charges to reach the electrode/electrolyte interface are the performance determining factors. 15 electrolytes are evaluated for their ionic conductivity and potential operating range. Among organic electrolytes NaPF6 dissolved in acetonitrile is determined to have the highest conductivity at 4.65 S/m. The operating voltage range of all electrolytes are limited due to impurities. Different types of polypyrrole, a conducting polymer, exhibiting double layer capacitance and pseudocapacitance are examined under different operating conditions. Among the ten different types of polypyrrole films evaluated, the best film achieves a maximum discharge energy density of 16.6 (J/g) and a maximum discharge power density of 1.15(W/g) according to single electrode measurements. To improve the performance of the polypyrrole films, composite electrodes based on electrodepositing polypyrrole on carbon fiber paper are produced. A cell based on these electrodes achieves a maximum discharge energy density of 12.5 (J/g) and a maximum discharge power density of 0.0134 (W/g) based on the mass of both electrodes. A novel carbon nanotube film fabrication method is employed to assemble supercapacitor cells with carbon nanotube electrodes. The best performing cell achieves a maximum discharge energy density of 4.79 (J/g) and a maximum discharge power density of 1.6 (W/g).

Jamming during the discharge of granular matter from a silo

description: In this work we present an experimental study of the jamming that stops the free flow of grains from a silo discharging by gravity. When the outlet size is not much bigger than the beads, granular material jams the outlet of the container due to the formation of an arch. Statistical data from the number of grains fallen between consecutive jams are presented. The information that they provide can help to understand the jamming phenomenon. As the ratio between the size of the orifice and the size of the beads is increased, the probability that an arch blocks the outlet decreases. We show here that there is a power law divergence of the mean avalanche size for a finite critical radius. Beyond this critical radius no jamming can occur and the flow is never stopped. The dependence of the arch formation on the shape and the material of the grains has been explored. It has been found that the material properties of the grains do not affect the arch formation probability. On the contrary, the shape of the grains deeply influences it. A simple model to interpret the results is also discussed.

Understanding the Indirect Effects of Interactive Systems Within Systems of Systems

description: Until recently, research into the sustainable design of interactive systems has primarily focused on the direct material impact of a system, through improving its energy efficiency and optimizing its lifecycle. Yet the way a system is designed and marketed often has wider repercussions, such as rebound effects, and systemic change in practices. These effects are harder to assess (and to anticipate) than the direct physical impact of the construction and use of the system itself. Current tools are unable to account for the complexity of these effects: the underlying causal mechanisms, their multi-level nature, their different temporalities, and the variety of their consequences (environmental and societal). This is why we are seeking to develop a specific methodology and tool, inspired by systemic design and system dynamics. These are intended for decision-makers and designers of interactive systems within systems of systems (for example, in the fields of agricultural robotics or public transportation). In this paper, we present this modeling approach and our prototype tool through the example of a second-hand clothing sales platform.

Lagrange Multipliers, Duality, and Sensitivity in Set-Valued Convex Programming via Pointed Closed Convex Processes

description: We present a new kind of Lagrangian duality theory for set-valued convex optimization problems whose objective and constraint maps are defined between preordered normed spaces. The theory is accomplished by introducing a new set-valued Lagrange multiplier theorem and a dual program with variables that are pointed closed convex processes. The pointed nature assumed for the processes is essential for the derivation of the main results presented in this research. We also develop a strong duality theorem that guarantees the existence of dual solutions, which are closely related to the sensitivity of the primal program. It allows extending the common methods used in the study of scalar programs to the set-valued vector case.

Self-dual effective action of N = 4 SYM revisited
Creators: name: Kuzenko, S. M.
Publisher: name: arXiv
Year: 2004
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: More evidence is provided for the conjectured correspondence between the D3-brane action in AdS_5 x S^5 and the low-energy effective action for N = 4 SU(N) SYM on its Coulomb branch, where the gauge group SU(N) is spontaneously broken to SU(N-1) x U(1) and the dynamics is described by a single N = 2 vector multiplet corresponding to the U(1) factor of the unbroken group. Using an off-shell formulation for N = 4 SYM in N = 2 harmonic superspace, within the background-field quantization scheme we compute the two-loop quantum correction to a holomorphic sector of the effective action, which is a supersymmetric completion of interactions of the form Ω((F^+)^2 |Y|^{-4}) (F^+)^2(F^-)^2 |Y|^{-4}, with F^\pm the (anti) self-dual components of the U(1) gauge field strength, and Y the complex scalar belonging to the vector multiplet. In the one-loop approximation, Ωwas shown in hep-th/9911221 to be constant. It is demonstrated in the present paper that Ω\propto (F^+)^2 |Y|^{-4} at the two-loop order. The corresponding coefficient proves to agree with the F^6 coefficient in the D3-brane action, after implementing the nonlinear field redefinition which was sketched in hep-th/9810152 and which relates the N = 2 vector multiplet component fields with those living on the D3-brane. In the approximation considered, our results are consistent with the conjecture of hep-th/9810152 that the N = 4 SYM effective action is self-dual under N = 2 superfield Legendre transformation, and also with the stronger conjecture of hep-th/0001068 that it is self-dual under supersymmetric U(1) duality rotations.

Probing the Microscopic Origin of Gravity via Precision Polarization and Spin Experiments

Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)
subject: FOS: Physical sciences

description: As in other parts of physics, we advocate the interaction approach: experiments phenomenology low-energy effective (field) theory microscopic theory to probe the microscopic origin of gravity. Using chi-g phenomenological framework, we discuss the tests of equivalence principles. The only experimentally unconstrained degree of freedom is the axion freedom. It has effects on the long-range astrophysical/cosmological propagation of electromagnetic waves and can be tested/measured using future generation of polarization measurement of cosmic background radiation. The verification or refutal of this axionic effect will be a crucial step for constructing effective theory and probing the microscopic origin of gravity. The interaction of spin with gravity is another important clue for probing microscopic origin of gravity. The interplay of experiments, phenomenology and effective theory is expounded. An ideal way to reveal the microscopic origin of gravity is to measure the gyrogravitational ratio of particles. Three potential experimental methods are considered.
