description: We apply the flow equation method for studying the fermion systems where pairing interactions can either trigger the BCS instability with the symmetry breaking manifested by the off-diagonal order parameter or lead to the gaped single particle spectrum without any symmetry breaking. We construct the continuous Bogoliubov transformation in a scheme resembling the renormalization group procedure. We further extend this continuous transformation to a case where fermion pairs interact with the boson field. Due to temporal quantum fluctuations the single particle excitation spectrum develops a gap which is centered around the renormalized boson energy. When bosons undergo the Bose Einstein condensation this structure evolves into the BCS spectrum.
The leuven embedded figures test (L-EFT): measuring perception or cognition?
Creators: name: Huygelier, Hanne
Publisher: name: F1000Research
Year: 2015

description: Our visual system prioritizes global structures above local elements. A myriad of tasks claim to dissociate local from global perception, but the constructs underlying these tasks remain unclear. One paradigm commonly used in this field is the Embedded Figures Test (EFT; Witkin, Ottman, Raskin & Karp, 1971) but its results have been prone to a wide variety of interpretations. In the current study, testing over 130 participants, we aimed at a better understanding of what is measured by the EFT. Therefore, a new EFT was designed where  several perceptual grouping cues were independently manipulated. Secondly, the association between EFT performance, non-verbal intelligence and several executive functions was assessed to evaluate the impact of cognitive aspects on EFT performance. These data could clarify the construct validity of this paradigmatic task of global/local processing. In addition, our newly designed EFT may offer a more controlled measure, which is better able to differentiate between genuine perceptual, as opposed to executive contributions to EFT performance.

description: In this paper we introduce a new method to locate highly connected clusters in a network. Our proposed approach adapts the HyperBall algorithm to localize regions with a high density of small subgraph patterns in large graphs in a memory-efficient manner. We use this method to evaluate three measures of subgraph connectivity: conductance, the number of triangles, and transitivity. We demonstrate that our algorithm, applied to these measures, helps to identify clustered regions in graphs, and provides good seed sets for community detection algorithms such as PageRank-Nibble. We analytically obtain the performance guarantees of our new algorithms, and demonstrate their effectiveness in a series of numerical experiments on synthetic and real-world networks.

description: We study gray solitons in nonlocal nonlinear media and show that they are stable and can form bound states. We reveal that gray soliton velocity depends on the nonlocality degree, and that it can be drastically reduced in highly nonlocal media. This is in contrast to the case of local media, where the maximal velocity is dictated solely by the asymptotic soliton amplitude.

description: Faster-absorbed soluble ibuprofen formulations provide faster analgesia and less need for remedication.  However, their gastrointestinal safety and tolerablity has been the subject of some discussion.  This study compared in vitro dissolution rates, pharmacokinetic data and spontaneously reported gastrointestinal events of 4 preparations of OTC ibuprofen to investigate the effect of formulation on GI tolerability. Liquid capsule formulations seem to be particularly well-tolerated.

description: A dynamical version of the Widom-Rowlinsom model in the continuum is considered. The dynamics is modelled by a spatial two-component birth-and-death Glauber process where particles, in addition, are allowed to change their type with density dependent rates. An evolution of states is constructed as the unique weak solution to the associated Fokker-Planck equation. Such solution is obtained by means of its correlation functions which belong to a certain Ruelle space. Existence of a unique invariant measure and ergodicity with exponential rate is established. The mesoscopic limit is considered, it is related with the verification of the chaos preservation property.

Granular mixtures modeled as elastic hard spheres subject to a drag force

description: Granular gaseous mixtures under rapid flow conditions are usually modeled by a multicomponent system of smooth inelastic hard spheres with constant coefficients of normal restitution. In the low density regime an adequate framework is provided by the set of coupled inelastic Boltzmann equations. Due to the intricacy of the inelastic Boltzmann collision operator, in this paper we propose a simpler model of elastic hard spheres subject to the action of an effective drag force, which mimics the effect of dissipation present in the original granular gas. The Navier--Stokes transport coefficients for a binary mixture are obtained from the model by application of the Chapman--Enskog method. The three coefficients associated with the mass flux are the same as those obtained from the inelastic Boltzmann equation, while the remaining four transport coefficients show a general good agreement, especially in the case of the thermal conductivity. Finally, the approximate decomposition of the inelastic Boltzmann collision operator is exploited to construct a model kinetic equation for granular mixtures as a direct extension of a known kinetic model for elastic collisions.

description: In a recent paper [Chaos 30, 073139 (2020)] we analyzed an extension of the Winfree model with nonlinear interactions. The nonlinear coupling function Q was mistakenly identified with the non-infinitesimal phase-response curve (PRC). Here, we asses to what extent Q and the actual PRC differ in practice. By means of numerical simulations, we compute the PRCs corresponding to the Q functions previously considered. The results confirm a qualitative similarity between the PRC and the coupling function Q in all cases.

Resonant spin polarization and spin current in a two-dimensional electron gas

description: We study the spin polarization and its associated spin-Hall current due to EDSR in disordered two-dimensional electron systems. We show that the disorder induced damping of the resonant spin polarization can be strongly reduced by an optimal field configuration that exploits the interference between Rashba and Dresselhaus spin-orbit interaction. This leads to a striking enhancement of the spin susceptibility while the spin-Hall current vanishes at the same time. We give an interpretation of the spin current in geometrical terms which are associated with the trajectories the polarization describes in spin space.

description: Taking Heisenberg's and Schrodinger's theories of quantum mechanics as his case study, De Regt's contextual theory of understanding argues that recognizing qualitatively characteristic consequences of a theory T without performing exact calculations is a criterion for scientific understanding. From the perspective of this theory of understanding, the task of understanding quantum mechanics seems to have been achieved already or even finished. This appears to disagree with some physicists' attitude to the understanding of quantum mechanics in line with Richard Feynman's famous slogan "I think I can safely say that nobody really understands quantum mechanics." Moreover, if the task of understanding quantum mechanics has been finished already, there would be a conflict between the contextual theory of understanding of quantum mechanics and interpretations of quantum mechanics.

An Adaptive Stable Space-Time FE Method for the Shallow Water Equations

description: We consider the finite element (FE) approximation of the shallow water equations (SWE) by considering discretizations in which both space and time are established using an unconditionally stable FE method. Particularly, we consider the automatic variationally stable FE (AVS-FE) method, a type of discontinuous Petrov-Galerkin (DPG) method. The philosophy of the DPG method allows us to break the test space and achieve unconditionally stable FE approximations as well as accurate a posteriori error estimators upon solution of a saddle point system of equations. The resulting error indicators allow us to employ mesh adaptive strategies and perform space-time mesh refinements, i.e., local time stepping. We derive a priori error estimates for the AVS-FE method and linearized SWE and perform numerical verifications to confirm corresponding asymptotic convergence behavior. In an effort to keep the computational cost low, we consider an alternative space-time approach in which the space-time domain is partitioned into finite sized space-time slices. Hence, we can perform adaptivity on each individual slice to preset error tolerances as needed for a particular application. Numerical verifications comparing the two alternatives indicate the space-time slices are superior for simulations over long times, whereas the solutions are indistinguishable for short times. Multiple numerical verifications show the adaptive mesh refinement capabilities of the AVS-FE method, as well the application of the method to commonly applied benchmarks for the SWE.

description: We solve the conjecture by R. Fenn, C. Rourke and B. Sanderson that the rack homology of dihedral quandles satisfies H_3^R(R_p) = Z \oplus Z_p for p odd prime. We also show that H_n^R(R_p) contains Z_p for n>2. Furthermore, we show that the torsion of H_n^R(R_3) is annihilated by 3. We also prove that the quandle homology H_4^Q(R_p) contains Z_p for p odd prime. We conjecture that for n>1 quandle homology satisfies: H_n^Q(R_p) = Z_p^{f_n}, where f_n are "delayed" Fibonacci numbers, that is, f_n = f_{n-1} + f_{n-3} and f(1)=f(2)=0, f(3)=1. Our paper is the first step in approaching this conjecture.

description: In this presentation, the shape of two-bladed bladed hubs (focus on the blade connection) is compared to the shape of three-bladed ones, to answer the question if oval-shaped blade connections could be beneficial for two-bladed turbines or not. Therefore an initial study was done, with the use of the method of stress equality between two-bladed and three-bladed cross-sections. Finally, different shaped blade connections of two-bladed and three-bladed turbines for different loads could be compared and the material reduction potentials of oval-shaped blade connection of two-bladed turbines could be calculated.

This chapter focuses on the overview of optimization, nature-inspired algorithms and the role of hybridization. We will also highlight some issues with hybridization of algorithms.

A new power line modem and its performance in power line channels
Creators: name: Zhong, Tao
Publisher: name: University of British Columbia
Year: 2009

description: Intrabuilding electrical power supply lines provide readily accessible communication links. The Hot and Neutral lines in power line cable are used as the transmission channel in most power line communications scenarios. The Hot-Neutral is a hostile communication channel with high noise, high signal attenuation, changing impedance and signal fading. To avoid these difficulties, the Neutral-Ground channel is proposed and tested. Using Neutral-Ground channels in power line communication has advantages of lower attenuation, reduced impulse noise, higher input resistance, less signal fading, and more stable links. Neutral-Ground channels are viable as communication links when the transmitter-receiver separation is large enough to cause excessive signal attenuation for Hot-Neutral links and are recommended as the transmission channels in power line communications wherever possible. A power line modem was designed and developed. The modem was built around an untested prototype Binary Phase Shift Keying (BPSK) modulation and demodulation VLSI chip. The modem is supervised and controlled by a microcontroller. The firmware offers robust modem parameter control and data link control. The power line modem was tested on Hot-Neutral and Neutral-Ground channels. The modem BER is reasonably close to that determined assuming a white Gaussian noise channel. Using Neutral-Ground channels enables power line communications over wider distances with less transmitting power than when Hot-Neutral channels are used. Communications in Neutral- Ground are not affected by either the power line phases of the transmitter and receiver or by electric loads on power lines. Using an appropriate communications protocol, the modems successfully transferred large files from one computer to another via in-building poxyer line links.

description: We study a spatial birth-and-death process on the phase space of locally finite configurations $Γ^+ \times Γ^-$ over $\mathbb{R}^d$. Dynamics is described by an non-equilibrium evolution of states obtained from the Fokker-Planck equation and associated with the Markov operator $L^+(γ^-) + \frac{1}{\varepsilon}L^-$, $\varepsilon > 0$. Here $L^-$ describes the environment process on $Γ^-$ and $L^+(γ^-)$ describes the system process on $Γ^+$, where $γ^-$ indicates that the corresponding birth-and-death rates depend on another locally finite configuration $γ^- \in Γ^-$. We prove that, for a certain class of birth-and-death rates, the corresponding Fokker-Planck equation is well-posed, i.e. there exists a unique evolution of states $μ_t^{\varepsilon}$ on $Γ^+ \times Γ^-$. Moreover, we give a sufficient condition such that the environment is ergodic with exponential rate. Let $μ_{\mathrm{inv}}$ be the invariant measure for the environment process on $Γ^-$. In the main part of this work we establish the stochastic averaging principle, i.e. we prove that the marginal of $μ_t^{\varepsilon}$ onto $Γ^+$ converges weakly to an evolution of states on $Γ^+$ associated with the averaged Markov birth-and-death operator $\overline{L} = \int_{Γ^-}L^+(γ^-)d μ_{\mathrm{inv}}(γ^-)$.

description: Quantum key distribution (QKD) can provide information theoretically secure key exchange even in the era of quantum computer. However, QKD requires the classical channel to be authenticated, and the current method is pre-sharing symmetric keys. For a QKD network of $n$ users, this method requires $C_n^2 = n(n-1)/2$ pairs of symmetric keys to realize pairwise interconnection. In contrast, with the help of mature public key infrastructure (PKI) and post-quantum cryptography (PQC) with quantum resistant security, each user only needs to apply for a digital certificate from certificate authority (CA) to achieve efficient and secure authentication for QKD. We only need to assume the short-term security of the PQC algorithm to achieve the long-term security of the distributed keys. Here, we experimentally verified the feasibility, efficiency and stability of the PQC algorithm in QKD authentication, and demonstrated the advantages when new users join the QKD network. Using PQC authentication we only need to believe the CA is safe, rather than all trusted relays. QKD combined with PQC authentication will greatly promote and extend the application prospects of quantum safe communication.

description: We analyse $\textit{XMM-Newton}$ RGS spectra of Wolf-Rayet (WR) 140, an archetype long-period eccentric WR+O colliding wind binary. We evaluate the spectra of O and Fe emission lines and find that the plasmas emitting these lines have the largest approaching velocities with the largest velocity dispersions between phases 0.935 and 0.968 where the inferior conjunction of the O star occurs. This behaviour is the same as that of the Ne line-emission plasma presented in our previous paper. We perform diagnosis of electron number density $n_{\rm e}$ using He-like triplet lines of O and Ne-like Fe-L lines. The former results in a conservative upper limit of $n_{\rm e} \lesssim 10^{10}$-10$^{12}$ cm$^{-3}$ on the O line-emission site, while the latter can not impose any constraint on the Fe line-emission site because of statistical limitations. We calculate the line-of-sight velocity and its dispersion separately along the shock cone. By comparing the observed and calculated line-of-sight velocities, we update the distance of the Ne line-emission site from the stagnation point. By assuming radiative cooling of the Ne line-emission plasma using the observed temperature and the local stellar wind density, we estimate the line-emission site extends along the shock cone by at most $\pm$58 per cent (phase 0.816) of the distance from the stagnation point. In this framework, excess of the observed velocity dispersion over the calculated one is ascribed to turbulence in the hot-shocked plasma at earlier orbital phases of 0.816, 0.912, and 0.935, with the largest velocity dispersion of 340-630 km s$^{-1}$ at phase 0.912.

description: We have used Bi$_2$Se$_3$ nanoribbons, grown by catalyst-free Physical Vapor Deposition to fabricate high quality Josephson junctions with Al superconducting electrodes. In our devices we observe a pronounced reduction of the Josephson critical current density $J_c$ by reducing the width of the junction, which in our case corresponds to the width of the nanoribbon. Because the topological surface states extend over the entire circumference of the nanoribbon, the superconducting transport associated to them is carried by modes on both the top and bottom surfaces of the nanoribbon. We show that the $J_c$ reduction as a function of the nanoribbons width can be accounted for by assuming that only the modes travelling on the top surface contribute to the Josephson transport as we derive by geometrical consideration. This finding is of a great relevance for topological quantum circuitry schemes, since it indicates that the Josephson current is mainly carried by the topological surface states.

description: In 1957, N. G. de Bruijn showed that the symmetric group Sym(Ω) on an infinite set Ωcontains a free subgroup on 2^{card(Ω)} generators, and proved a more general statement, a sample consequence of which is that for any group A of cardinality \leq card(Ω), Sym(Ω) contains a coproduct of 2^{card(Ω)} copies of A, not only in the variety of all groups, but in any variety of groups to which A belongs. His key lemma is here generalized to an arbitrary variety of algebras \bf{V}, and formulated as a statement about functors Set --> \bf{V}. From this one easily obtains analogs of the results stated above with "group" and Sym(Ω) replaced by "monoid" and the monoid Self(Ω) of endomaps of Ω, by "associative K-algebra" and the K-algebra End_K(V) of endomorphisms of a K-vector-space V with basis Ω, and by "lattice" and the lattice Equiv(Ω) of equivalence relations on Ω. It is also shown, extending another result from de Bruijn's 1957 paper, that each of Sym(Ω), Self(Ω) and End_K (V) contains a coproduct of 2^{card(Ω)} copies of itself. That paper also gave an example of a group of cardinality 2^{card(Ω)} that was {\em not} embeddable in Sym(Ω), and R. McKenzie subsequently established a large class of such examples. Those results are shown to be instances of a general property of the lattice of solution sets in Sym(Ω) of sets of equations with constants in Sym(Ω). Again, similar results -- this time of varying strengths -- are obtained for Self(Ω), End_K (V), and Equiv(Ω), and also for the monoid \Rel of binary relations on Ω. Many open questions and areas for further investigation are noted.

description: We consider a hydrodynamic model of a quantum dusty plasma. We prove mathematically that the resulting dust ion acoustic plasma waves present the property of being conservative on average. Furthermore, we test this property numerically, confirming its validity. Using standard techniques from the study of dynamical systems, as for example the Lyapunov characteristic exponents, we investigate the chaotic dynamics of the plasma and show numerically its existence for a wide range of parameter values. Finally, we illustrate how chaotic dynamics organizes in the parameter space for fixed values of the initial conditions, as the Mach number and the quantum diffraction parameter are continuously varied.

description: We have demonstrated Zeeman slowing and capture of neutral Ra-225 and Ra-226 atoms in a magneto-optical trap (MOT). The intercombination transition 1S0-3P1 is the only quasi-cycling transition in radium and was used for laser-cooling and trapping. Repumping along the 3D1-1P1 transition extended the lifetime of the trap from milliseconds to seconds. Room-temperature blackbody radiation was demonstrated to provide repumping from the metastable 3P0 level. We measured the isotope shift and hyperfine splittings on the 3D1-1P1 transition with the laser-cooled atoms, and set a limit on the lifetime of the 3D1 level based on the measured blackbody repumping rate. Laser-cooled and trapped radium is an attractive system for studying fundamental symmetries.

A nonequilibrium renormalization group approach to turbulent reheating

Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: We use nonequilibrium renormalization group (RG) techniques to analyze the thermalization process in quantum field theory, and by extension reheating after inflation. Even if at a high scale $Λ$ the theory is described by a non-dissipative $λϕ^{4}$ theory, the RG running induces nontrivial noise and dissipation. For long wavelength, slowly varying field configurations, the noise and dissipation are white and ohmic, respectively. The theory will then tend to thermalize to an effective temperature given by the fluctuation-dissipation theorem.

Effects of transient non-thermal particles on the big bang nucleosynthesis

description: The effects of introducing a small amount of non-thermal distribution (NTD) of elements in big bang nucleosynthesis (BBN) are studied by allowing a fraction of the NTD to be time-dependent so that it contributes only during a certain period of the BBN evolution. The fraction is modeled as a Gaussian-shaped function of $\log(T)$, where $T$ is the temperature of the cosmos, and thus the function is specified by three parameters; the central temporal position, the width and the magnitude. The change in the average nuclear reaction rates due to the presence of the NTD is assumed to be proportional to the Maxwellian reaction rates but with temperature $T_{\rm NTD} \equiv ζT$, $ζ$ being another parameter of our model. By scanning a wide four-dimensional parametric space at about half a million points, we have found about 130 points with $χ^2< 1$, at which the predicted primordial abundances of light elements are consistent with the observations. The magnitude parameter $\varepsilon_0$ of these points turns out to be scattered over a very wide range from $\varepsilon_0 \sim 10^{-19}$ to $\sim 10^{-1}$, and the $ζ$-parameter is found to be strongly correlated with the magnitude parameter $\varepsilon_0$. The temperature region with $0.3\times 10^9 \mbox{K} \lesssim T \lesssim 0.4\times 10^9 \mbox{K}$ or the temporal region $t\simeq 10^3$ s seems to play a central role in lowering $χ^2$.

Anomalous field effect and glassy behaviour in granular aluminium thin films: electron glass?

description: We present a study of non-equilibrium phenomena observed in the electrical conductance of insulating granular aluminium thin films. An anomalous field effect and its slow relaxation are studied in some detail. The phenomenology is very similar to the one already observed in indium oxide. The origin of the phenomena is discussed. In granular systems, the present experiments can naturally be interpreted along two different lines. One relies on a slow polarisation in the dielectric surrounding the metallic islands. The other one relies on a purely electronic mechanism: the formation of an electron Coulomb glass in the granular metal. More selective experiments and/or quantitative predictions about the Coulomb glass properties are still needed to definitely distinguish between the two scenarii.

description: We developed a method to characterize arbitrary superpositions of light orbital angular momentum (OAM) with high fidelity by using astigmatic tomography and machine learning processing. In order to define each superposition unequivocally, we combine two intensity measurements. The first one is the direct image of the input beam, which cannot distinguish between opposite OAM components. This ambiguity is removed by a second image obtained after astigmatic transformation of the input beam. Samples of these image pairs are used to train a convolution neural network and achieve high fidelity recognition of arbitrary OAM superpositions with dimension up to five.
Faculty/Researcher Survey on Data Curation

Subjects: digital curation

description: In 2012 the Data Curation @ UCSB Project surveyed UCSB campus faculty and researchers on the subject of data curation, with the goals of 1) better understanding the scope of the digital curation problem and the curation services that are needed, and 2) characterizing the role that the UCSB Library might play in supporting curation of campus research outputs. The project received responses from one-third of the estimated target audience of 900, indicating great interest in the topic and yielding statistically significant results. The findings argue for the establishment of a campus unit possessing data curation expertise and providing curation-related assistance to campus researchers, and possibly hosting curation services (as necessary and as funding allows).

Holevo Bound of Entropic Uncertainty in Schwarzschild Spacetime

description: For a pair of incompatible quantum measurements, the total uncertainty can be bounded by a state-independent constant. However, such a bound can be violated if the quantum system is entangled with another quantum system (called memory); the quantum correlation between the systems can reduce the measurement uncertainty. On the other hand, in a curved spacetime, the presence of the Hawking radiation can increase the uncertainty in quantum measurement. The interplay of quantum correlation in the curved spacetime has become an interesting arena for studying quantum uncertainty relations. Here we demonstrate that the bounds of the entropic uncertainty relations, in the presence of memory, can be formulated in terms of the Holevo quantity, which limits how much information can be encoded in a quantum system. Specifically, we considered two examples with Dirac fields, near the event horizon of a Schwarzschild black hole, the Holevo bound provides a better bound than the previous bound based on the mutual information. Furthermore, if the memory moves away from the black hole, the difference between the total uncertainty and the Holevo bound remains a constant, not depending on any property of the black hole.

Dexterity enhancement in microsurgery using a microgripper and motion-scaling system
Creators: name: Ku, Shyan
Publisher: name: University of British Columbia
Year: 2009

description: The design and control of a six-degree-of-freedom (6-DOF) force-reflecting motion-scaling teleoperation system was presented in [1]. In this thesis, a remotely controlled microgripper is developed as an end-effector for this system. The device features small size and weight, and large stroke and force compared to other designs. A stylus-shaped teleoperation master that measures the force at the fingers of the operator provides an intuitive means for operating the microgripper. This design also enables the microgripper to be used as a hand-held instrument. Force sensing enables the accurate measurement and control of tool-tissue forces, as well as the emulation of different mechanical devices. Issues concerning the design, control, and application to microsurgical tasks are addressed here. 6-DOF force/torque sensing has also been added to the teleoperation system, enabling the use of hand and environment forces to improve teleoperation transparency, and enabling the measurement of forces during microsurgery. Several methods for teleoperation control have been implemented, and their potential use in microsurgery is discussed. In addition, experiments have been conducted to quantify the effects of scaled motion and scaled force feedback on teleoperation performance in tasks involving sub-millimetre motions and contact forces from 3 to 15 grams. Significant improvements in accuracy of task execution as well as operator confidence and fatigue were observed when scaled motion and scaled force feedback were provided.

description: We present short \chandra observations of twelve bright (i<18) z_em~1.5 quasars from the Sloan Digital Sky Survey chosen to have significantly redder optical colors than most quasars at the same redshift. Of the five quasars with optical properties most consistent with dust reddening at the quasar redshift, four show indirect evidence of moderate X-ray absorption (inferred N_H~10^22 cm^-2) with a dust-to-gas ratio <1% of the SMC value. The remaining seven objects show no evidence for even moderate intrinsic X-ray absorption. Thus, while optically red quasars are marginally more likely to show signatures of X-ray absorption than optically selected quasars with normal colors, dust-reddened type 1 AGN (as opposed to fully obscured type 2 AGN) are unlikely to contribute significantly to the remaining unresolved hard X-ray background. The red quasar population includes objects with intrinsically red continua as well as objects with dust-reddened continua. Improved sample selection is thus needed to increase our understanding of either subpopulation. To identify dust-reddened quasars likely to exhibit X-ray absorption, some measure of spectral curvature is preferable to simple cuts in observed or relative broad-band colors.
