description: We present Herschel-PACS observations of rest-frame mid-infrared and far-infrared spectral line emissions from two lensed, ultra-luminous infrared galaxies at high redshift: MIPS J142824.0+352619 (MIPS J1428), a starburst-dominated system at z = 1.3, and IRAS F10214+4724 (F10214), a source at z = 2.3 hosting both star-formation and a luminous AGN. We have detected [OI]63 micron and [OIII]52 micron in MIPS J1428, and tentatively [OIII]52 micron in F10214. Together with the recent ZEUS-CSO [CII]158 micron detection in MIPS J1428 we can for the first time combine [OI], [CII] and far-IR (FIR) continuum measurements for photo-dissociation (PDR) modeling of an ultra-luminous (L_IR > 10^12 L_sun) star forming galaxy at the peak epoch of cosmic star formation. We find that MIPS J1428, contrary to average local ULIRGs, does not show a deficit in [OI] relative to FIR. The combination of far-UV flux G_0 and gas density n (derived from the PDR models), as well as the star formation efficiency (derived from CO and FIR) is similar to normal or starburst galaxies, despite the high infrared luminosity of this system. In contrast, F10214 has stringent upper limits on [OIV] and [SIII], and an [OIII]/FIR ratio at least an order of magnitude lower than local starbursts or AGN, similar to local ULIRGs.

Entropy Production during Asymptotically Safe Inflation

Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: The Asymptotic Safety scenario predicts that the deep ultraviolet of Quantum Einstein Gravity is governed by a nontrivial renormalization group fixed point. Analyzing its implications for cosmology using renormalization group improved Einstein equations we find that it can give rise to a phase of inflationary expansion in the early Universe. Inflation is a pure quantum effect here and requires no inflaton field. It is driven by the cosmological constant and ends automatically when the renormalization group evolution has reduced the vacuum energy to the level of the matter energy density. The quantum gravity effects also provide a natural mechanism for the generation of entropy. It could easily account for the entire entropy of the present Universe in the massless sector.

Subjects: subject: Classical Analysis and ODEs (math.CA)

description: This paper discusses the approximation by %semigroups of operators of class ($\mathscr{C}_0$) on the sphere and focuses on a class of so called exponential-type multiplier operators. It is proved that such operators form a strongly continuous semigroup of contraction operators of class ($\mathscr{C}_0$), from which the equivalence between approximation for these operators and $K$-functionals introduced by the operators is given. As examples, the constructed $r$-th Boolean of generalized spherical Abel-Poisson operator and $r$-th Boolean of generalized spherical Weierstrass operator denoted by $\oplus^r V_t^γ$ and $\oplus^r W_t^κ$ separately ($r$ is any positive integer, $00$) satisfy that $\|\oplus^r V_t^γf - f\|_{\mathcal{X}}\approx ω^{rγ}(f,t^{1/γ})_{\mathcal{X}}$ and $\|\oplus^r W_t^κf - f\|_{\mathcal{X}}\approx ω^{2rγ}(f,t^{1/(2κ)})_{\mathcal{X}}$, for all $f\in \mathcal{X}$, where $\mathcal{X}$ is a Banach space of continuous functions or $\mathcal{L}^p$-integrable functions ($1\leq p0$ for $f\in \mathcal{X}$. The saturation order and saturation class of the regular exponential-type multiplier operators with positive kernels are also obtained. Moreover, it is proved that $\oplus^r V_t^γ$ and $\oplus^r W_t^κ$ have the same saturation class if $γ=2κ$.

description: From the beginning of quantum mechanics, there has been a discussion about the concept of reality, as exemplified by the EPR paradox. To many, the idea of the paradox and the possibility of local hidden variables was dismissed by the Bell inequality. Yet, there remains considerable evidence that this inequality can be violated even by classical systems, so that experiments showing quantum behavior and the violation of the inequality must be questioned. Here, we demonstrate that classical optical polarization experiments based upon noise in the system can be shown to violate the Bell inequality.

Evolution of Massive Protostars via Disk Accretion

description: Mass accretion onto (proto-)stars at high accretion rates > 10^-4 M_sun/yr is expected in massive star formation. We study the evolution of massive protostars at such high rates by numerically solving the stellar structure equations. In this paper we examine the evolution via disk accretion. We consider a limiting case of "cold" disk accretion, whereby most of the stellar photosphere can radiate freely with negligible backwarming from the accretion flow, and the accreting material settles onto the star with the same specific entropy as the photosphere. We compare our results to the calculated evolution via spherically symmetric accretion, the opposite limit, whereby the material accreting onto the star contains the entropy produced in the accretion shock front. We examine how different accretion geometries affect the evolution of massive protostars. For cold disk accretion at 10^-3 M_sun/yr the radius of a protostar is initially small, about a few R_sun. After several solar masses have accreted, the protostar begins to bloat up and for M \simeq 10 M_sun the stellar radius attains its maximum of 30 - 400 R_sun. The large radius about 100 R_sun is also a feature of spherically symmetric accretion at the same accreted mass and accretion rate. Hence, expansion to a large radius is a robust feature of accreting massive protostars. At later times the protostar eventually begins to contract and reaches the Zero-Age Main-Sequence (ZAMS) for M \simeq 30 M_sun, independent of the accretion geometry. For accretion rates exceeding several 10^-3 M_sun/yr the protostar never contracts to the ZAMS. The very large radius of several 100s R_sun results in a low effective temperature and low UV luminosity of the protostar. Such bloated protostars could well explain the existence of bright high-mass protostellar objects, which lack detectable HII regions.

Dynamical Lorentz symmetry breaking and topological defects

description: I discuss the possibility of topological defect solutions in field theories containing a tensor field which spontaneously breaks Lorentz symmetry. I find that for theories of a tensor with rank r <= 5 and for which the vacuum manifold consists of the tensors whose "square" is some constant value, only three types of tensor (vectors, antisymmetric two-tensors, and symmetric two-tensors) have the appropriate vacuum manifold topology to support topological defects. Of these, topological defect solutions can be easily constructed for two: vector domain wall solutions and antisymmetric tensor monopole solutions. These antisymmetric tensor monopole solutions are in principle detectible via their gravitational lensing effects.

Towards automatic broadcast of team sports
Creators: name: Chen, Jianhui
Publisher: name: University of British Columbia
Year: 2018

description: Sports is the social glue of society as it allows people to interact with each other and appreciate games irrespective of their social status, age and ethnicity. Automatic sports broadcasting produces stream videos from vision sensors without human intervention. The goal is to predict where cameras should look and which camera should be on air. The technique can benefit millions of people as most viewers participant in sports by watching TV or Internet broadcasting. The target team sports include basketball, soccer and ice hockey in which team members quickly move their positions in the game, excluding sports like baseball and cricket in which team members have relatively stable positions. Automatic sports broadcasting covers areas of statistics, commentary, camera control and so on. We provide solutions for automatically setting camera parameters such as camera orientation angles and locations using computer vision. We restrict our attention to static pan-tilt-zoom (PTZ) cameras for television or live Internet broadcasting. We propose three essential components of autonomous broadcasting: camera calibration, planning and selection. By learning from human demonstrations, our work can predict camera angles for single camera systems and camera viewpoints for multi-camera systems. We obtain human demonstrations from existing videos that are generated by professional camera operators. These videos contain camera angles and camera IDs if there are multiple cameras. Because camera angles are not directly available, we first propose two novel camera calibration methods. We evaluate and compare our methods with previous algorithms. Our methods are more accurate and faster than previous algorithms. With labeled data from human operators, we develop two methods for smooth camera planning which predict camera pan angles. The first method directly incorporates temporal consistency into a data-driven predictor. The second method optimizes the camera trajectory in overlapped temporal windows. We show they outperform previous methods in the literature. We also propose two methods for selecting a broadcast camera view from multiple candidate camera views. The first method uses deep features for camera selection. The second method augments the training data with Internet videos. We demonstrate comparable results with selections from human operators in soccer games.

Nonlinear evolution of coarse-grained quantum systems with generalized purity constraints
Creators: name: Buric, Nikola
Publisher: name: arXiv
Year: 2010
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: Constrained quantum dynamics is used to propose a nonlinear dynamical equation for pure states of a generalized coarse-grained system. The relevant constraint is given either by the generalized purity or by the generalized invariant fluctuation, and the coarse-grained pure states correspond to the generalized coherent i.e. generalized nonentangled states. Open system model of the coarse-graining is discussed. It is shown that in this model and in the weak coupling limit the constrained dynamical equations coincide with an equation for pointer states, based on Hilbert-Schmidt distance, that was previously suggested in the context of the decoherence theory.

description: Diagrammatic techniques to compute perturbatively the spectral properties of Euclidean Random Matrices in the high-density regime are introduced and discussed in detail. Such techniques are developed in two alternative and very different formulations of the mathematical problem and are shown to give identical results up to second order in the perturbative expansion. One method, based on writing the so-called resolvent function as a Taylor series, allows to group the diagrams in a small number of topological classes, providing a simple way to determine the infrared (small momenta) behavior of the theory up to third order, which is of interest for the comparison with experiments. The other method, which reformulates the problem as a field theory, can instead be used to study the infrared behaviour at any perturbative order.

Elastohydrodynamic interactions at small scales
Creators: name: Nasouri, Babak
Publisher: name: University of British Columbia
Year: 2018

description: In this dissertation, the effects of elasticity on hydrodynamic interactions at small scales are investigated. In the microscale realm of microorganisms, inertia is irrelevant and viscous dissipation dominates the fluid motion and particles within it. As a result of this inertialess environment, microorganisms use non-reciprocal body distortions to facilitate locomotion and exhibit nontrivial behaviors in interacting with their surroundings; behaviors that have been shown to be intimately correlated to the elasticity of the cell body, or its small appendages called flagella (or cilia). Motivated by experimental observations, the effects of elasticity on hydrodynamic interactions of motile cells are investigated, using theoretical approaches. First, to model the flow field induced by microswimmers, a framework is given to account for the effects of the higher-order force moments. Specifically, the contribution of the second-order force moments of the flow field is evaluated, and explicit formulas are reported for the stresslet dipole, rotlet dipole, and potential dipole for an arbitrarily shaped active particle. For an elastic swimmer near a boundary, it is shown that the rotlet dipole bends the swimmer and results in qualitatively different swimming behaviors in comparison to the case of a rigid swimmer. Furthermore, it is demonstrated that elasticity can be exploited to evade the kinematic reversibility of the field equations in Stokes flow. A model elastic swimmer is proposed that despite the reversible actuation, can propel forward due to its nonreciprocal body deformations. The effect of elasticity in the formation of metachronal waves in ciliated microorganisms such as Paramecium and Volvox is also studied. Using a minimal model, it is shown that elastohydrodynamic interactions of cilia attached to a curved body lead to synchronization, with zero phase difference, thereby preventing the formation of wave-like behaviors unless an asymmetry is introduced to the system. Finally, the dynamics of capillary rise between two porous and elastic sheets are investigated. The liquid, as it rises, diffuses through the sheets and changes their properties. The significant drop in sheet bending rigidity due to wetting, causes the system to coalesce faster, compared to the case of impermeable sheets, and also remarkably reduces the absorbance capacity.

description: While generative artificial intelligence (Gen AI) increasingly transforms academic environments, a critical gap exists in understanding and mitigating human biases in AI interactions, such as anchoring and confirmation bias. This position paper advocates for metacognitive AI literacy interventions to help university students critically engage with AI and address biases across the Human-AI interaction workflows. The paper presents the importance of considering (1) metacognitive support with deliberate friction focusing on human bias; (2) bi-directional Human-AI interaction intervention addressing both input formulation and output interpretation; and (3) adaptive scaffolding that responds to diverse user engagement patterns. These frameworks are illustrated through ongoing work on "DeBiasMe," AIED (AI in Education) interventions designed to enhance awareness of cognitive biases while empowering user agency in AI interactions. The paper invites multiple stakeholders to engage in discussions on design and evaluation methods for scaffolding mechanisms, bias visualization, and analysis frameworks. This position contributes to the emerging field of AI-augmented learning by emphasizing the critical role of metacognition in helping students navigate the complex interaction between human, statistical, and systemic biases in AI use while highlighting how cognitive adaptation to AI systems must be explicitly integrated into comprehensive AI literacy frameworks.

description: We introduce and analyze a system of two coupled partial differential equations with external noise. The equations are constructed to model transitions of monovalent metallic nanowires with non-axisymmetric intermediate or end states, but also have more general applicability. They provide a rare example of a system for which an exact solution of nonuniform stationary states can be found. We find a transition in activation behavior as the interval length on which the fields are defined is varied. We discuss several applications to physical problems.

description: We study a large population of globally coupled phase oscillators subject to common white Gaussian noise and find analytically that the critical coupling strength between oscillators for synchronization transition decreases with an increase in the intensity of common noise. Thus, common noise promotes the onset of synchronization. Our prediction is confirmed by numerical simulations of the phase oscillators as well as of limit-cycle oscillators.

description: A possible origin of the anomalous dip and bump in the primordial power spectrum, which are reconstructed from WMAP data corresponding to the multipole $\ell=100\sim 140$ by using the inversion method, is investigated as a consequence of modification of scalar field dynamics in the inflation era. Utilizing an analytic formula to handle higher order corrections to the slow-roll approximation, we evaluate the relation between a detailed shape of inflaton potential and a fine structure in the primordial power spectrum. We conclude that it is unlikely to generate the observed dip and bump in the power spectrum by adding any features in the inflaton potential. Though we can make a fine enough shape in the power spectrum by controlling the feature of the potential, the amplitude of the dip and bump becomes too small in that case.

Urban Solid Waste Management: Understanding the Fault Lines and its Best Practices

Subjects: Solid Waste Management Rules, 2016; Draft Urban Solid Waste Management Policy, 2018, decentralised approach

description: Located in the Northeast, Guwahati is the largest city and metropolis in the region. According to the 2011 Census, Guwahati (metro) has a population of 962,334, which is expected to grow as urbanisation continues. Urbanisation makes solid waste management more challenging and complicated unless appropriately planned. In the most recent Swachh Surveskshan Index 2021, Guwahati ranked 312, up from 356 in 2020 (GMC, 2022). Guwahati (through the Guwahati Municipal Corporation) must, however, overhaul its overall functions to reap benefits from its strategic location as the gateway to the Northeast and the rest of Southeast Asian neighbouring countries. It is clear from the literature review that Guwahati's solid waste management needs to be timelier and more unplanned. Several papers have examined its lacunas in certain aspects, but they have yet to discuss its fault lines while linking solid waste management to the Swachh Bharat Mission. The Assam State government has adopted a piecemeal approach to address the issue. There has yet to be much progress. The paper seeks to answer two broader questions: (1) What are the current lacunas/gaps in the management of the waste management system in Guwahati? (a)How successful has Guwahati Municipal Corporation (GMC) been in trying to achieve the objective of Solid Waste Management Rules 2016? (b)How is the present solid waste management policy impacting the lives of the people living in Guwahati and adjoining areas? (2) What are the best practices that can be incorporated into the current system so that there can be a sustainable change in solid waste management practices and behaviour in Guwahati? Upon analysing these questions, it becomes apparent that structural issues in the GMC's functioning contribute to its consistently low ranking in the Swachh Survekhsan Index. Secondly, the comparison with other smaller cities (Titabor) or Indore (a larger metropolitan area) shows that public engagement is the key to transforming solid waste management. While the Swachh Bharat Mission (SBM) has raised awareness about cleanliness, the link between cleaning and dumping at a dump site on the one hand and managing solid waste sustainably and effectively on the other, needs to be understood.

description: A discussion is given of the conformal Einstein field equations coupled with matter whose energy-momentum tensor is trace-free. These resulting equations are expressed in terms of a generic Weyl connection. The article shows how in the presence of matter it is possible to construct a conformal gauge which allows to know \emph{a priori} the location of the conformal boundary. In vacuum this gauge reduces to the so-called conformal Gaussian gauge. These ideas are applied to obtain: (i) a new proof of the stability of Einstein-Maxwell de Sitter-like spacetimes; (ii) a proof of the semi-global stability of purely radiative Einstein-Maxwell spacetimes.

description: The trapped magnetic field is examined in bulk high-temperature superconductors that are artificially drilled along their c-axis. The influence of the hole pattern on the magnetization is studied and compared by means of numerical models and Hall probe mapping techniques. To this aim, we consider two bulk YBCO samples with a rectangular cross-section that are drilled each by six holes arranged either on a rectangular lattice (sample I) or on a centered rectangular lattice (sample II). For the numerical analysis, three different models are considered for calculating the trapped flux: (i), a two-dimensional (2D) Bean model neglecting demagnetizing effects and flux creep, (ii), a 2D finite-element model neglecting demagnetizing effects but incorporating magnetic relaxation in the form of an E-J power law, and, (iii), a 3D finite element analysis that takes into account both the finite height of the sample and flux creep effects. For the experimental analysis, the trapped magnetic flux density is measured above the sample surface by Hall probe mapping performed before and after the drilling process. The maximum trapped flux density in the drilled samples is found to be smaller than that in the plain samples. The smallest magnetization drop is found for sample II, with the centered rectangular lattice. This result is confirmed by the numerical models. In each sample, the relative drops that are calculated independently with the three different models are in good agreement. As observed experimentally, the magnetization drop calculated in the sample II is the smallest one and its relative value is comparable to the measured one. By contrast, the measured magnetization drop in sample (1) is much larger than that predicted by the simulations, most likely because of a change of the microstructure during the drilling process.

Leading order one-loop CP and P violating effective action in the Standard Model

description: The fermions of the Standard Model are integrated out to obtain the effective Lagrangian in the sector violating P and CP at zero temperature. We confirm that no contributions arise for operators of dimension six or less and show that the leading operators are of dimension eight. To assert this we explicitly compute one such non-vanishing contribution, namely, that with three Z^0, two W^+ and two W^-. Terms involving just gluons and W's are also considered, however, they turn out to vanish in the P-odd sector to eighth order. The analogous gluonic term in the CP-odd and P-even (C-odd) sector is non-vanishing and it is also computed. The expressions derived apply directly to Dirac massive neutrinos. All CP-violating results display the infrared enhancement already found at dimension six.

description: A leading hypothesis for the nature of the elusive dark matter are thermally produced, weakly interacting massive particles that arise in many theories beyond the standard model of particle physics. Their self-annihilation in astrophysical regions of high density provides a potential means of indirectly detecting dark matter through the annihilation products, which nicely complements direct and collider searches. Here, I review the case of gamma rays which are particularly promising in this respect: distinct and unambiguous spectral signatures would not only allow a clear discrimination from astrophysical backgrounds but also to extract important properties of the dark matter particles; powerful observational facilities like the Fermi Gamma-ray Space Telescope or upcoming large, ground-based Cherenkov telescope arrays will be able to probe a considerable part of the underlying, e.g. supersymmetric, parameter space. I conclude with a more detailed comparison of indirect and direct dark matter searches, showing that these two approaches are, indeed, complementary.

Water at the silica surface : effect of ions and temperature
Creators: name: Lovering, Kaitlin
Publisher: name: University of British Columbia
Year: 2018

description: This dissertation studies the silica/water interface using sum frequency generation spectroscopy. The effects of alkali chloride ions and temperature on the hydrogen bonding network at the interface are examined. We observed that the structure of water in the Stern layer depends on the identity of the cation. The ability of a cation to displace the hydration water on silica surface is in the order of Mg²⁺ > Ca²⁺ > Li⁺ > Na⁺, consistent with the trend of the acid dissociation constant of the salt. We conclude that ions with a high pKa, such as Mg²⁺ and Ca²⁺, have a local electrostatic field strong enough to polarize water molecules in the hydration shells of the ions. These partially hydrolyzed water molecules form linkages with the negative charges on the silica, forming solvent shared ion pairs. During freezing of pure water, we observed a transient phase of ice at water/mineral interfaces, which had enhanced IR-visible sum frequency generation intensity for several minutes. Most forms of ice are centrosymmetric but a possible explanation of for the transient phase is the formation of stacking-disordered ice during the freezing process. Stacking-disordered ice, which has only been observed in the bulk ice at temperatures lower than -20 °C, is a random mixture of layers of hexagonal ice and cubic ice. The transient phase at the ice/mineral interface was observed at temperatures as high as -1 °C. This observation suggests that the mineral surface may play a role in promoting the formation of the stacking-disordered ice at the interface. The effect of ions during freezing at the silica/water interface was investigated. Ice is the first phase to form. NaCl·2H₂O forms below the eutectic temperature, indicating that the formation and growth of ice does not push the ions out of the interfacial region. We compared the surface freezing diagram with the bulk equilibrium phase diagram of aqueous sodium chloride solutions. Although the concentration of ions is higher at a charged surface, we observe that freezing point depression at the surface is analogous to freezing point depression for homogeneous freezing and bulk equilibrium phase diagram.

description: We present new limits on the ejection of metal-rich old-population hypervelocity stars from the Galactic center (GC) as probed by the SEGUE-2 survey. Our limits are a factor of 3-10 more stringent than previously reported, depending on stellar type. Compared to the known population of B-star ejectees, there can be no more than 30 times more metal-rich old-population F/G stars ejected from the GC. Because B stars comprise a tiny fraction of a normal stellar population, this places significant limits on a combination of the GC mass function and the ejection mechanism for hypervelocity stars. In the presence of a normal GC mass function, our results require an ejection mechanism that is about 5.5 times more efficient at ejecting B-stars compared to low-mass F/G stars.

description: The quasiparticle states around a nonmagnetic impurity in electron-doped iron-based superconductors with spin-density-wave (SDW) order are investigated as a function of doping and impurity scattering strength. In the undoped sample, where a pure SDW state exists, two impurity-induced resonance peaks are observed around the impurity site and they are shifted to higher (lower) energies as the strength of the positive (negative) scattering potential (SP) is increased. For the doped samples where the SDW order and the superconducting order coexist, the main feature is the existence of sharp in-gap resonance peaks whose positions and intensity depend on the strength of the SP and the doping concentration. In all cases, the local density of states exhibits clear $C_2$ symmetry. We also note that in the doped cases, the impurity will divide the system into two sublattices with distinct values of magnetic order. Here we use the band structure of a two-orbital model, which considers the asymmetry of the As atoms above and below the Fe-Fe plane. This model is suitable to study the properties of the surface layers in the iron-pnictides and should be more appropriate to describe the scanning tunneling microscopy experiments.

description: We examine the distribution of axis ratios of a large sample of disk galaxies hosting type 2 AGNs selected from the Sloan Digital Sky Survey and compare it with a well-defined control sample of non-active galaxies. We find them significantly different, where the type 2 AGNs show both an excess of edge-on objects and deficit of round objects. This systematical bias can not be explained by a nuclear obscurer oriented randomly with respect to the stellar disk. However, a nuclear obscurer coplanar with the stellar disk also does not fit the data very well. By assuming that the nuclear obscurer having an opening angle of ~60 degree, we find the observed axis ratio distribution can be nicely reproduced by a mean tilt angle of ~30 degree between the nuclear obscurer and the stellar disk.
