description: The discovery of unidirectional invisibility and its broadband realization in optical media satisfying spatial Kramers-Kronig relations are important landmarks of non-Hermitian photonics. We offer a precise characterization of a higher-dimensional generalization of this effect and find sufficient conditions for its realization in the scattering of scalar waves in two and three dimensions and electromagnetic waves in three dimensions. More specifically, given a positive real number $α$ and a continuum of unit vectors $Ω$, we provide explicit conditions on the interaction potential (or the permittivity and permeability tensors of the scattering medium in the case of electromagnetic scattering) under which it displays perfect (non-approximate) invisibility whenever the incident wavenumber $k$ does not exceed $α$ (i.e., $k\in(0,α]$) and the direction of the incident wave vector ranges over $Ω$. A distinctive feature of our approach is that it allows for the construction of potentials and linear dielectric media that display perfect directional invisibility in a finite frequency domain.

description: Utility-based power allocation in wireless ad-hoc networks is inherently nonconvex because of the global coupling induced by the co-channel interference. To tackle this challenge, we first show that the globally optimal point lies on the boundary of the feasible region, which is utilized as a basis to transform the utility maximization problem into an equivalent max-min problem with more structure. By using extended duality theory, penalty multipliers are introduced for penalizing the constraint violations, and the minimum weighted utility maximization problem is then decomposed into subproblems for individual users to devise a distributed stochastic power control algorithm, where each user stochastically adjusts its target utility to improve the total utility by simulated annealing. The proposed distributed power control algorithm can guarantee global optimality at the cost of slow convergence due to simulated annealing involved in the global optimization. The geometric cooling scheme and suitable penalty parameters are used to improve the convergence rate. Next, by integrating the stochastic power control approach with the back-pressure algorithm, we develop a joint scheduling and power allocation policy to stabilize the queueing systems. Finally, we generalize the above distributed power control algorithms to multicast communications, and show their global optimality for multicast traffic.

A proposal for a new kind of spontaneous collapse model
Creators: name: Piccione, Nicolò
Publisher: name: arXiv

Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: Spontaneous collapse models are modifications of standard quantum mechanics in which a physical mechanism is responsible for the collapse of the wavefunction, thus providing a way to solve the so-called "measurement problem". The two most famous of these models are the Ghirardi-Rimini-Weber (GRW) model and the Continuous Spontaneous Localisation (CSL) models. Here, we propose a new kind of non-relativistic spontaneous collapse model based on the idea of collapse points situated at fixed spacetime coordinates. This model shares properties of both GRW and CSL models, while starting from different assumptions. We show that it can lead to a dynamics quite similar to that of the GRW model while also naturally solving the problem of indistinguishable particles. On the other hand, we can also obtain the same master equation of the CSL models. Then, we show how our proposed model solves the measurement problem in a manner conceptually similar to the GRW model. Finally, we show how the proposed model can also accommodate for Newtonian gravity by treating the collapses as gravitational sources.

Kondratieff et al. (2006) reported P. puttmanni from the Little River (Harnett/Cumberland Co., Little River, Hwy 401, Lillington, 18 May 2004), as a new state record for North Carolina. Re-examination of this material indicated that the specific status of these P. decipens complex specimens is uncertain requiring study of the entire complex. Such a study is outside the scope of this paper. However, the Lee/Chatham Co., Deep River specimen is clearly P. puttmanni validating the occurrence of this species in North Carolina.

description: Using first-principles density functional calculations, a systematic study on the elastic properties for all known superconducting MAX phases (Nb2SC, Nb2SnC, Nb2AsC, Nb2InC, Mo2GaC and Ti2InC) was performed. As a result, the optimized lattice parameters, independent elastic constants, indicators of elastic anisotropy and brittle/ductile behavior as well as the so-called machinability indexis were calculated. We derived also bulk and shear moduli, Young's moduli, and Poisson's ratio for ideal polycrystalline MAX aggregates. The results obtained were discussed in comparison with available theoretical and experimental data and elastic parameters for other layered superconductors.

description: The Lorentz symmetry of gravity is spontaneously broken when the nonminimally coupled Kalb-Ramond field acquires a nonzero vacuum expectation value. In this work, we present exact solutions for static and spherically symmetric black holes in the framework of this Lorentz-violating gravity theory. In order to explore the physical implications of Lorentz violation, we analyze the thermodynamic properties of the obtained solutions and evaluate the impact of Lorentz violation on some classical gravitational experiments within the Solar System. Furthermore, the Lorentz-violating parameter is constrained by using the measured results of these experiments.

The influence of abiotic and biotic factors on the geographic distribution of spider sociality : insights from a factor exclusion and transplant experiment
Creators: name: Hoffman, Catherine
Publisher: name: University of British Columbia
Year: 2014

description: Species ranges, which are manifestations of species ecological niches in space, are generally determined by gradients of abiotic and biotic factors. In group-living organisms, not only the properties of individuals, but also those of their groups, should interact with environmental challenges and opportunities to determine a species range. Social and subsocial spiders are well known for having distinct geographical distributions. Intriguingly, subsocial species in the genus Anelosimus are absent from the lowland tropical rainforest where social congeners thrive. Previous studies have attributed this absence to increasing rain intensity and predation, particularly by ants, closer to the rainforest. After confirming that these factors do indeed increase in intensity approaching the lowland tropical rainforest, I test these hypotheses by transplanting nests of the subsocial Anelosimus elegans from its native lower montane cloud forest (1000m) to the lowland tropical rainforest (400m). At both locations I performed a fully factorial ant and rain exclusion experiment and monitored colony survival over time. I found that survival was lower in the lowlands, but improved by the exclusion of rain and ants. At the native higher elevation habitat, in contrast, colony survival did not differ between treatments and controls, confirming that neither intense rains nor predation are factors that negatively impact colony survival in the native habitat. At both locations, large colonies were able to build more webbing, suggesting that larger groups with limited dispersal may benefit from reduced per capita web maintenance in addition to increased predator protection. These findings would explain why subsocial Anelosimus, with small single-family groups and dense webs, have been unable to colonize the lowland tropical rainforest where their social congeners thrive.

description: The tunneling of composite systems, where breakup may occur during the barrier penetration process is considered in connection with the fusion of halo-like radioactive, neutron- and proton-rich nuclei on heavy targets. The large amount of recent and new data clearly indicates that breakup hinders the fusion at near and below the Coulomb barrier energies. However, clear evidence for the halo enhancements, seems to over ride the breakup hindrance at lower energies, owing, to a large extent, to the extended matter density distribution. In particular we report here that at sub-barrier energies the fusion cross section of the Borromean two-neutron halo nucleus $^{6}$He with the actinide nucleus $^{238}$U is significantly enhanced compared to the fusion of a no-halo $^{6}$He. This conclusion differs from that of the original work, where it was claimed that no such enhancement ensues. This sub-barrier fusion enhancement was also observed in the $^{6}$He + $^{209}$% Bi system. The role of the corresponding easily excitable low lying dipole pygmy resonance in these systems is therefore significant. The consequence of this overall enhanced fusion of halo nuclei at sub-barrier energies, on stellar evolution and nucleosynthesis is evident.

description: Carbon atoms are counted at near atomic-level precision using a scanning transmission electron microscope calibrated by carbon nanocluster mass standards. A linear calibration curve governs the working zone from a few carbon atoms up to 34,000 atoms. This linearity enables adequate averaging of the scattering cross sections, imparting the experiment with near atomic-level precision despite the use of a coarse mass reference. An example of this approach is provided for thin layers of stacked graphene sheets. Suspended sheets with a thickness below 100 nm are visualized, providing quantitative measurement in a regime inaccessible to optical and scanning probe methods.
The Near-Flat-Space and BMN Limits for Strings in AdS4 x CP3 at One Loop

description: This paper studies type IIA string theory in AdS4 x CP3 in both the BMN limit and the Maldacena-Swanson or near-flat-space limit. We derive the simpler Lagrangian for the latter limit by taking a large worldsheet boost of the BMN theory. We then calculate one-loop corrections to the correlators of the various fields using both theories. In all cases the near-flat-space results agree with a limit of the BMN results, providing evidence for the quantum consistency of this truncation. The corrections can also be compared to an expansion of the exact dispersion relation, known from integrability apart from one interpolating function h(lambda). Here we see agreement with the results of McLoughlin, Roiban & Tseytlin, and we observe that it does not appear to be possible to fully implement the cutoff suggested by Gromov & Mikhaylov, although for some terms we can do so. In both the near-flat-space and BMN calculations there are some extra terms in the mass shifts which break supersymmetry. These terms are extremely sensitive to the cutoff used, and can perhaps be seen as a consequence of using dimensional regularisation.

A New System Noise Measurement Method Using a 2-bit Analog-To-Digital Converter

description: We propose a new method to measure the system noise temperature, $T_{\rm sys}$, using a 2-bit analog-to-digital converter (ADC). The statistics of the digitized signal in a four-level quantization brings us information about the bias voltage and the variance, which reflects the power of the input signal. Comparison of the variances in {\it hot} and {\it sky} circumstances yields $T_{\rm sys}$ without a power meter. We performed test experiments using the Kagoshima 6-m radio telescope and a 2-bit ADC to verify this method. Linearity in the power-variance relation was better than 99% within the dynamic range of 10 dB. Digitally measured $T_{\rm sys}$ coincided with that of conventional measurement with a power meter in 1.8-% difference or less for elevations of $10^{\circ} - 88^{\circ}$. No significant impact was found by the bias voltages within the range between -3.7 and +12.8% with respect to the threshold voltage. The proposed method is available for existing interferometers that have a multi-level ADC, and release us from troubles caused by power meters.

description: We study chaotic behavior of order parameters in two coupled ensembles of self-sustained oscillators. Coupling within each of these ensembles is switched on and off alternately, while the mutual interaction between these two subsystems is arranged through quadratic nonlinear coupling. We show numerically that in the course of alternating Kuramoto transitions to synchrony and back to asynchrony, the exchange of excitations between two subpopulations proceeds in such a way that their collective phases are governed by an expanding circle map similar to the Bernoulli map. We perform the Lyapunov analysis of the dynamics and discuss finite-size effects.

Few active mechanisms of the neutrinoless double beta-decay and effective mass of Majorana neutrinos

description: It is well known that there exist many mechanisms that may contribute to neutrinoless double beta decay (0nbb-decay). By exploiting the fact that the associated nuclear matrix elements are target dependent we show that, given definite experimental results on a sufficient number of targets, one can determine or sufficiently constrain all lepton violating parameters including the mass term. As a specific example we show that, assuming the observation of the 0nbb-decay in three different nuclei, e.g., 76Ge, 100Mo and 130Te, and just three lepton number violating mechanisms (light and heavy neutrino mass mechanisms as well as R-parity breaking SUSY mechanism) being active, there are only four different solutions for the lepton violating parameters, provided that they are relatively real. In particular, assuming evidence of the 0nbb-decay of 76Ge, the effective neutrino Majorana mass |m_bb| can be almost uniquely extracted by utilizing other existing constraints (cosmological observations and tritium beta-decay experiments). We also point out the possibility that the non-observation of the 0nbb-decay for some isotopes could be in agreement with a value of |m_bb| in sub eV region. We thus suggest that it is important to have at least two different 0nbb-decay experiments for a given nucleus.

description: In this work, we study parametric resonances in an elongated cigar-shaped BEC in a combined harmonic trap and a time dependent optical lattice by using numerical and analytical techniques. We show that there exists a relative competition between the harmonic trap which tries to spatially localize the BEC and the time varying optical lattice which tries to delocalize the BEC. This competition gives rise to parametric resonances (collapse and revival of the oscillations of the BEC width). Parametric resonances disappear when one of the competing factors i.e strength of harmonic trap or the strength of optical lattice dominates. Parametric instabilities (exponential growth of Bogoliubov modes) arise for large variations in the strength of the optical lattice.

Fatty acids composition (C10:0, C11:0, C12:0, C13:0, C14:1, C18:0, C18:2 cis-9, trans-11, γ-C18:3, α-C18:3, C20:0, C20:1 and C22:0), vitamin A and oxidative stability were differed between region, but were not affected by stage of lactation. Differences in milk composition could be related to region differences because the use of grass-based forage and altitude condition in four regions. The oxidation stability of milk was closely related to monounsaturated fatty acids (MUFA) and all-trans-retinol. MUFA were negatively correlated with superoxide dismutase (r = −0.207). All-trans-retinol was positively correlated with total antioxidant capacity value (0.208), and negatively correlated with thiobarbituric acid reactive substances (r = −0.265). These findings may be used to assess and improve milk quality of china.

For that we invoke a combination of a group theoretical analysis with ab initio density functional theory calculations and uncover a rich phase diagram with various non-trivial topological phases beyond a Weyl semimetallic state, such as axion and topological crystalline insulating phases, and discuss their realization.

description: Chemical reactions taking place in active centers of different enzymes are controlled by electric fields created by the protein in these centers. These electric fields can be experimentally detected by different experimental techniques (infrared absorption, NMR, etc.). In this paper, we use quantum chemical calculations to show that Mössbauer spectroscopy can be also used to study protein electric field. We study effect of both the model and protein electric fields on the magnitude of quadrupole splitting of Mössbauer spectra of the high-spin ferrous myoglobin and its models. It is shown that the quadrupole splitting is notably affected by the protein electric field. This result also explains a number of the experimental data.

The Virginia material appears indistinguishable from typical P. browni from the Ozarks, although this species was considered an “endemic to the region” by Poulton and Stewart (1991). Further studies, especially of the eggs of this disjunct Virginia population may help resolve the status of this taxon. The type locality for P. cranshawi Kondratieff and Kirchner, 2006 is from this same site on the Nottoway River.

description: Fungal spores with allergenic potential are a predominant biological component in the atmosphere of Puerto Rico. Spores of basidiomycete fungi, such as Ganoderma spp, often outnumber the atmospheric concentration of mitosporic fungi and pollen from trees and grass. Nevertheless, extracts from basidiomycetes are not currently available for serological testing and knowledge of the relationship of reactivity with commercial extracts is limited. Spearman correlation matrices were generated, on an archived dataset, to identify relationships between reactivity to G. applanatum spore’s cytoplasmic extracts tested in ELISA (crude) and Western blot (19, 24, 33, 45, 56, 75, and 81 kDa) with reactivity to indoor, pests, farm animals, and pollen allergens commercial extracts. Also, principal component analysis was employed to identify clusters of variables explaining inter-subjects variabilities in reactivities. Only the reactivity to dog danger was highly correlated with the crude extract (r =0.48, p < 0.001), but the 45 and 75 kDa polypeptides were correlated with reactivities to mitosporic fungi (Alternaria, Aspergillus, Fusarium, Cladosporium), Mucor, pests (American cockroach, mouse, rat), and farm animal danders (chicken, horse) (r = .30 to 57, p = 0.04 to < 0.001). G. applanatum’s polypeptides (except the 19 kDa) clustered together in explaining 21% of the variability among the subjects’ reactivities. These results suggests that reactivity to mitosporic fungi, indoor allergens, and allergens from farm animals pose a respiratory health risk from exposures to G. applanatum fungal spores. Our findings also further support the relevance of G. applamatum as an important outdoor allergen among the Puerto Rico population.

description: We introduce the notion of Lombardi graph drawings, named after the American abstract artist Mark Lombardi. In these drawings, edges are represented as circular arcs rather than as line segments or polylines, and the vertices have perfect angular resolution: the edges are equally spaced around each vertex. We describe algorithms for finding Lombardi drawings of regular graphs, graphs of bounded degeneracy, and certain families of planar graphs.

Searching for Heavy Leptophilic $Z'$: from Lepton Colliders to Gravitational Waves

description: We study the phenomenology of leptophilic $Z'$ gauge bosons at the future high-energy $e^+e^-$ and $μ^+μ^-$ colliders, as well as at the gravitational wave observatories. The leptophilic $Z'$ model, although well-motivated, remains largely unconstrained from current low-energy and collider searches for $Z'$ masses above ${\cal O}(100~{\rm GeV})$, thus providing a unique opportunity for future lepton colliders. Taking $U(1)_{L_α-L_β}~(α,β=e,μ,τ)$ models as concrete examples, we show that future $e^+e^-$ and $μ^+μ^-$ colliders with multi-TeV center-of-mass energies provide unprecedented sensitivity to heavy leptophilic $Z'$ bosons. Moreover, if these $U(1)$ models are classically scale-invariant, the phase transition at the $U(1)$ symmetry-breaking scale tends to be strongly first-order with ultra-supercooling, and leads to observable stochastic gravitational wave signatures. We find that the future sensitivity of gravitational wave observatories, such as advanced LIGO-VIRGO and Cosmic Explorer, can be complementary to the collider experiments, probing higher $Z'$ masses up to ${\cal O}(10^4~{\rm TeV})$, while being consistent with naturalness and perturbativity considerations.

Essays on macroeconomics and corporate behavior
Creators: name: Wang, Mingzhi
Publisher: name: University of British Columbia
Year: 2014

description: This dissertation focuses on the link between corporate behavior and macroeconomic phenomena. It is comprised of three separate but related chapters: The first chapter asks whether increases in firms' outsourcing can explain the downward trend of the investment to GDP ratio of the US. I develop a model with heterogeneous firms and a fixed cost to enter outsourcing. I test the model's implications using a novel dataset collected from US computer manufacturing firms' annual reports and find that empirical facts are consistent with the model. I find outsourcing firms invest less while produce more. Also, the lessening effect of outsourcing on investment is increasing over time. In the second paper I first show that the divergent trends in the macro and micro volatility of output is nonexistent after the year 2000. Then I argue that rapid technological innovation in the 80s and 90s contributes to these divergent trends. I explain the driving force of the different patterns of volatility using a model in which firms' investment has both long term and short term gains. Higher long term gain leads more firms to invest in risky projects resulting in higher micro volatility. At the same time, more participation contributes to better diversification at the aggregate level, hence lower macro volatility. The third chapter investigates the stock market's reaction to monetary policy shocks. I use the Romer and Romer(2005) measure of policy shocks and event study approach to perform this task. I find that stock market returns respond to monetary policy shocks. There is an asymmetry in the reaction in terms of boom and recession periods, small firms are more sensitive to shocks than large firms, highly leveraged firms are more sensitive to shocks than those with less leverage. These findings shed new lights on whether monetary authority should take into account the effects on financial market when making monetary policy changes.

Electronic Orders Induced by Kondo Effect in Non-Kramers f-Electron Systems

description: This paper clarifies the microscopic nature of the staggered scalar order, which is specific to even number of f electrons per site. In such systems, crystalline electric field (CEF) can make a singlet ground state. As exchange interaction with conduction electrons increases, the CEF singlet at each site gives way to Kondo singlets. The collective Kondo singlets are identified with itinerant states that form energy bands. Near the boundary of itinerant and localized states, a new type of electronic order appears with staggered Kondo and CEF singlets. We present a phenomenological three-state model that qualitatively reproduces the characteristic phase diagram, which have been obtained numerically with use of the continuous-time quantum Monte Carlo combined with the dynamical mean-field theory. The scalar order observed in PrFe_4P_{12} is ascribed to this staggered order accompanying charge density wave (CDW) of conduction electrons. Accurate photoemission and tunneling spectroscopy should be able to probe sharp peaks below and above the Fermi level in the ordered phase.

Monotone optimal policies for quasivariational inequalities arising in optimal portfolio liquidation
Creators: name: Crawford, Daniel J.
Publisher: name: University of British Columbia
Year: 2014

description: This thesis studies the Hamilton-Jacobi-Ballman quasivariational inequality (HJBQVI), the corresponding optimal value function, and discrete schemes useful for approximating this value function. Moreover, the structural properties of the optimal policy of particular discrete scheme is studied. The motivation is to find a convergent, approximating scheme for the otherwise complicated HJBQVI that has monotone policy structure that can be exploited in a stochastic gradient estimation scheme to approximate optimal policy function parameters. In order to motivate this approach, we consider the problem of optimal liquidation of a single risky asset portfolio as an impulse control problem. The model is defined over continuous time, state, and compact action sets, and the optimal liquidation value and strategy are found from the viscosity solution of a HJBQVI. It is shown that the optimal strategy is monotone in the number of shares owned and the time remaining to liquidation. This structural result is exploited to estimate the optimal policy via a reinforcement learning method based on the simultaneous perturbation stochastic approximation (SPSA) algorithm. The optimal policy can be estimated without knowledge of the parameters of the underlying model.

description: Exclusive meson leptoproduction from nucleons in the deeply virtual exchanged boson limit can be described by generalized parton distributions (GPDs). Including spin dependence in the description requires 8 independent quark-parton and gluon-parton functions. The chiral even subset of 4 quark-nucleon GPDs are related to nucleon form factors and to parton distribution functions. The chiral odd set of 4 quark-nucleon GPDs are related to transversity, the tensor charge, and other quantities related to transversity. Different meson or photon production processes access different combinations of GPDs. This is analyzed in terms of $t$-channel exchange quantum numbers, $J^{PC}$ and it is shown that pseudoscalar production can isolate chiral odd GPDs. There is a sensitive dependence in various cross sections and asymmetries on the tensor charge of the nucleon and other transversity parameters. In a second section, analyticity and completeness are shown to limit the partonic interpretation of the GPDs in the ERBL region.

Gaia view of primitive inner-belt asteroid families: Searching for the origins of asteroids Bennu and Ryugu

description: Near-Earth asteroids Ryugu and Bennu, were visited, characterised, and sampled by the Hayabusa2 and OSIRIS-REx missions: remote sensing data and sample return analysis showed that both asteroids have primitive, hydrated and organic-rich compositions. The dark families of the inner main belt (IMB) that belong to the spectroscopic C-complex have been claimed to be the sources of both Ryugu and Bennu. Hence, there has been large effort to characterise them. Here we used the Gaia Data Release 3 (DR3) asteroid reflectance spectra to investigate the 11 known IMB C-complex families (Chaldaea, Chimaera, Clarissa, Erigone, Eulalia, Klio, Polana, Primordial, Sulamitis, Svea, Tamara). For each family, we extracted the family members that have known geometric visible albedo values and Gaia DR3 data and we created an average reflectance spectrum per family between 370 and 950 nm. The average DR3 reflectance spectra of each family were compared with the previous literature data and to Bennu's and Ryugu's spectra. We found that DR3 reflectance spectra of the IMB C-complex families are in general consistent with previous findings with the only exception of the Svea family. We also showed that the Polana and the Eulalia families can be distinguished in the wavelength region 370 - 500 nm. Among all the IMB C-complex families, we determined that the average reflectance spectra of the Eulalia and Polana families are the most similar to those of Bennu and Ryugu, respectively. In particular, Eulalia family's average spectrum is a good match to Bennu's in the wavelength range 450 - 800 nm, while beyond 800 nm the spectrum of Bennu is bluer than that of Eulalia. Moreover, the spectrum of the Polana family has the smallest discrepancy against the spectrum of Ryugu, although this match is formally unsatisfactory (reduced chi^2 ~ 1.9).

description: The Socialists’ opposition to war in France, Germany and Italy during the period of the Second International (1889-1914) was contradictory. They tried to combine internationalism, antiwar engagement and anti-militarism with patriotic ideals and the defense of the nation in case of danger. This resulted in war in 1914. Therefore, is it really possible to speak of a “socialist Pacifism”?
