description: We obtain compatible Hamiltonian and symplectic structure for a new two-component fifth-order integrable system recently found by Mikhailov, Novikov and Wang (arXiv:0712.1972), and show that this system possesses a hereditary recursion operator and infinitely many commuting symmetries and conservation laws, as well as infinitely many compatible Hamiltonian and symplectic structures, and is therefore completely integrable. The system in question admits a reduction to the Kaup--Kupershmidt equation.

description: We report the results of a search for a heavy neutral gauge boson Z' decaying into the dielectron final state using data corresponding to an integrated luminosity of 5.4 fb-1 collected by the D0 experiment at the Fermilab Tevatron Collider. No significant excess above the standard model prediction is observed in the dielectron invariant-mass spectrum. We set 95% C.L. upper limits on σ(ppbar -> Z') X BR(Z' -> ee) depending on the dielectron invariant mass. These cross section limits are used to determine lower mass limits for Z' bosons in a variety of models with standard model couplings and variable strength.

description: The Andromeda galaxy (M31) hosts a central super-massive black hole (SMBH), known as M31$^\ast$, which is remarkable for its mass ($\sim$$10^8{\rm~M_\odot}$) and extreme radiative quiescence. Over the past decade, the Chandra X-ray observatory has pointed to the center of M31 $\sim$100 times and accumulated a total exposure of $\sim$900 ks. Based on these observations, we present an X-ray study of a highly variable source that we associate with M31$^\ast$ based on positional coincidence. We find that M31$^\ast$ remained in a quiescent state from late 1999 to 2005, exhibiting an average 0.5-8 keV luminosity $\lesssim$$10^{36}{\rm~ergs~s^{-1}}$, or only $\sim$$10^{-10}$ of its Eddington luminosity. We report the discovery of an outburst that occurred on January 6, 2006, during which M31$^\ast$ radiated at $\sim$$4.3\times10^{37}{\rm~ergs~s^{-1}}$. After the outburst, M31$^\ast$ entered a more active state that apparently lasts to the present, which is characterized by frequent flux variability around an average luminosity of $\sim$$4.8\times10^{36}{\rm~ergs~s^{-1}}$. These flux variations are similar to the X-ray flares found in the SMBH of our Galaxy (Sgr A$^\ast$), making M31$^\ast$ the second SMBH known to exhibit recurrent flares. Future coordinated X-ray/radio observations will provide useful constraints on the physical origin of the flaring emission and help rule out a possible stellar origin of the X-ray source.

A New Extension of Hořava-Lifshitz Gravity and Curing Pathologies of the Scalar Graviton

description: We consider an extension of the Hořava-Lifshitz gravity with extra conformal symmetry by introducing a scalar field with higher order curvature terms. Relaxing the exact local Weyl symmetry, we construct an action with three free parameters which breaks local anisotropic Weyl symmetry but still preserves residual global Weyl symmetry. At low energies, it reduces to a Lorentz-violating scalar-tensor gravity. With a constant scalar field background and particular choices of the parameters, it reduces to the Hořava-Lifshitz (HL) gravity, but any perturbation from these particular configurations produces some non-trivial extensions of HL gravity. The perturbation analysis of the new extended HL gravity in the Minkowski background shows thatthe pathological behaviors of scalar graviton, i.e., ghost or instability problem, and strong coupling problem do not emerge up to cubic order as well as quadratic order.

A new perspective on globular clusters, their initial mass function, and their contribution to the stellar halo and to cosmic reionisation

description: We examine various implications from a dynamical and chemical model of globular clusters (GCs), which successfully reproduces the observed abundance patterns and the multiple populations of stars in these systems assuming chemical enrichment from fast rotating massive stars. Using the model of Decressin et al. (2007) we determine the ratio between the observed, present-day mass of globular clusters and their initial stellar mass as a function of the stellar initial mass function (IMF). We also compute the mass of low-mass stars ejected, and the amount of hydrogen ionising photons emitted by the proto globular clusters. Typically, we find that the initial masses of GCs must be ~8-10 times (or up to 25 times, if second generation stars also escape from GCs) larger than the present-day stellar mass. The present-day Galactic GC population must then have contributed to approximately 5-8% (10-20%) of the low-mass stars in the Galactic halo. We also show that the detection of second generation stars in the Galactic halo, recently announced by different groups, provides a new constraint on the GC initial mass function (GCIMF). These observations appear to rule out a power-law GCIMF, whereas they are compatible with a log-normal one. Finally, the high initial masses also imply that GCs must have emitted a large amount of ionising photons in the early Universe. Our results reopen the question on the initial mass function of GCs, and reinforce earlier conclusions that old GCs could have represented a significant contribution to reionise the inter-galactic medium at high redshift.

On the design of injection-locked frequency dividers for mm-wave applications
Creators: name: Bodepu, Lakshmi Lavanya
Publisher: name: University of British Columbia
Year: 2020

description: This work presents the design and measurement results of two injection-locked frequency dividers (ILFDs) that are intended for mm-wave applications. The two prototypes are fabricated in a 65-nm CMOS process. The first direct-injection ILFD achieves a measured locking range of 24.5 GHz to 43 GHz while consuming 1.3 mW from a 0.48-V supply with a 0 dBm input injection power. The second ILFD design is based on the dual-injection multi-band architecture and as compared to the first design enhances the locking range by a factor of 2. The dual-injection ILFD achieves a locking range of 18 GHz to 61 GHz while consuming 1.8 mW from a 0.5-V supply with a 0 dBm input injection power. The design is optimized to improve the locking range and avoid in-band loss of lock which is a drawback of transformer-based higher order ILFDs. Furthermore, techniques such as shunt inductor peaking to reduce power consumption and dual-injection of the input signal through a distributed multi-order resonator to improve the locking range are explored and discussed. The best achieved locking range is 108.8 % at 39.5 GHz. The locking range obtained makes the divider suitable for integration in a multi-band mm-wave frequency synthesizer that can support international roaming.

description: The recent "breakdown criterion" result of S. Klainerman and I. Rodnianski stated roughly that an Einstein-vacuum spacetime, given as a CMC foliation, can be further extended in time if the second fundamental form and the derivative of the lapse of the foliation are uniformly bounded. This theorem and its proof were extended to Einstein-scalar and Einstein-Maxwell spacetimes in the author's Ph.D. thesis. In this paper, we state the main results of the thesis, and we summarize and discuss their proofs. In particular, we will discuss the various issues resulting from nontrivial Ricci curvature and the coupling between the Einstein and the field equations.

Testing gravity using the growth of large scale structure in the Universe

description: Future galaxy surveys hope to distinguish between the dark energy and modified gravity scenarios for the accelerating expansion of the Universe using the distortion of clustering in redshift space. The aim is to model the form and size of the distortion to infer the rate at which large scale structure grows. We test this hypothesis and assess the performance of current theoretical models for the redshift space distortion using large volume N-body simulations of the gravitational instability process. We simulate competing cosmological models which have identical expansion histories - one is a quintessence dark energy model with a scalar field and the other is a modified gravity model with a time varying gravitational constant - and demonstrate that they do indeed produce different redshift space distortions. This is the first time this approach has been verified using a technique that can follow the growth of structure at the required level of accuracy. Our comparisons show that theoretical models for the redshift space distortion based on linear perturbation theory give a surprisingly poor description of the simulation results. Furthermore, the application of such models can give rise to catastrophic systematic errors leading to incorrect interpretation of the observations. We show that an improved model is able to extract the correct growth rate. Further enhancements to theoretical models of redshift space distortions, calibrated against simulations, are needed to fully exploit the forthcoming high precision clustering measurements.

Value-based real option analysis to support early-stage drug development
Creators: name: Shin, Woo Suk
Publisher: name: University of British Columbia
Year: 2019

description: Background: Value-based frameworks link costs with health outcomes and are considered in drug reimbursement, suggesting the increasing need to estimate commercial performance of novel drugs in relation to demonstrating cost-effectiveness. Objective: To develop a value-based drug development framework and evaluate a commercialization strategy for a phase 1 drug candidate for hypoglycemia in type 1 diabetes (T1D). Methods: A value-based real options analysis (VB-ROA) framework was developed to incorporate payer and for-profit investor perspectives by integrating cost-effectiveness analysis (CEA) with real options analysis (ROA). The framework was applied to commercially evaluate a phase 1 drug candidate to prevent hypoglycemia. The VB-ROA framework was constructed in two stages: 1. Value-based price was estimated using headroom analysis based a Markov model assuming a US payers’ willingness to pay (WTP, λ) of $50,000 per quality-adjusted life year (QALY) and payers’ discount rate (rd) of 3%. The drug candidate’s target product profile (TPP) was based on clinician reports on meaningful health improvements. 2. ROA via the binomial lattice option pricing model (BOPM) using revenues based on value-based pricing and a cost of capital (rc) of 13.2%. Data to populate model parameters were gathered from published clinical, regulatory, and market data. Results: The value-based drug price was $5,178 (95% CI $4,437, $5,956) per year per patient. The phase 1 development option value was $0 (V₀,₁). The development strategy could be abandoned or revised, which may involve partnering non-profit institutions. If successful, the development option for phase 2 is $67 Million (V₁,₁) or $0 (V₁,₂). If development leads to regulatory approval, the option value to launch ranges from $8,716 Million (V₇,₁) to $127 Million (V₇,₈). Sensitive parameters to option value include investors’ cost of capital (rc), drug price, development risks (θt), market share, λ, health-related quality of life (HRQoL) weights, and the relative risk of non-severe hypoglycemia (RRNSHday & RRNSHnoc). Conclusions: The VB-ROA framework aligns patient, payer, and investor incentives to assess the impact of clinical and cost-effectiveness parameters on the commercial potential of novel drugs, which further enables the development novel drugs that are affordable for payers and patients, while profitable for investors.

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

description: We show that in the decoupling limit of an F-theory compactification, the internal directions of the seven-branes must wrap a non-commutative four-cycle S. We introduce a general method for obtaining fuzzy geometric spaces via toric geometry, and develop tools for engineering four-dimensional GUT models from this non-commutative setup. We obtain the chiral matter content and Yukawa couplings, and show that the theory has a finite Kaluza-Klein spectrum. The value of 1/alpha_(GUT) is predicted to be equal to the number of fuzzy points on the internal four-cycle S. This relation puts a non-trivial restriction on the space of gauge theories that can arise as a limit of F-theory. By viewing the seven-brane as tiled by D3-branes sitting at the N fuzzy points of the geometry, we argue that this theory admits a holographic dual description in the large N limit. We also entertain the possibility of constructing string models with large fuzzy extra dimensions, but with a high scale for quantum gravity.

description: For a distinguished water molecule, the solute water, we assess the contribution of each coordination state to its excess chemical potential, using a molecular aufbau approach. In this approach, we define a coordination sphere, the inner-shell, and separate the excess chemical potential into packing, outer-shell, and local chemical contributions; the coordination state is defined by the number of solvent water molecules within the coordination sphere. The packing term accounts for the free energy of creating a solute-free coordination sphere in the liquid. The outer-shell term accounts for the interaction of the solute with the fluid outside the coordination sphere and it is accurately described by a Gaussian model of hydration for coordination radii greater than the minimum of the oxygen-oxygen pair correlation function. Consistent with the conventional radial cut-off used for defining hydrogen-bonds in liquid water, theory helps identify a chemically meaningful coordination radius. The local chemical contribution is recast as a sum over coordination states. The n-th term in this sum is given by the probability of observing n water molecules inside the coordination sphere in the absence of the solute water times a factor accounting for the interaction of the solute with the inner-shell solvent water molecules. Using this molecular aufbau expansion, we monitor the change in the chemical contribution due to the incremental increase in n. We find that though four water molecules are needed to fully account for the chemical term, the first added water accounts for nearly half the chemical term. Our results emphasize the need to acknowledge the intrinsic occupancy of a solute-free coordination sphere together with solute-solvent interactions in rationalizing the tetrahedral coordination of the solute water.

description: We study the quantum moduli space of N=2 Chern-Simons quivers with generic ranks and CS levels, proving along the way exact formulas for the charges of bare monopole operators. We then derive N=2 Chern-Simons quiver theories dual to AdS_4 x Y^{p,q}(CP2) M-theory backgrounds, for the whole family of Sasaki-Einstein seven-manifolds and for any value of the torsion G_4 flux. The derivation of the gauge theories relies on the reduction to type IIA string theory, in which M2-branes become D2-branes while the conical geometry maps to RR flux and D6-branes wrapped on compact four-cycles. M5-branes on torsion cycles map to flux and wrapped D4-branes. The moduli space of the quiver is shown to contain the corresponding CY_4 cone and all its crepant resolutions.

description: The article analyzes the categories «culture», «language», «code», identifies their semasiological features, structural properties and functioning. Both cultural and linguistic codes effectively translate meaning only within the framework of to a certain extent closed societies - ethnic or other social groups. And it is the possibility of communication and the transfer of experience that simultaneously helps to unite the members of these groups and exclude outsiders from them. Thanks to this isolation of languages and cultures, different societies develop and organize in different ways, making up an amazing ethno-cultural diversity. A close study of these phenomena makes it possible to detect their stable interdependencies and coevolutionary relationships that contribute to the formation of the paradigmatic nature of connections. The consideration of linguistic and philosophical concepts gives grounds for a deeper insight into the problem of the language’ cultural code.
Energy Relaxation in a 1-D Polariton Condensate

description: We study the kinetics of polariton condensation accounting for the condensation process as well as the energy relaxation of condensed polaritons due to their scattering with phonons and excitons. By assuming a Boltzmann kinetic description of the scattering process, we show that intra-condensate relaxation can be accounted for by an additional time-dependent term in the Gross-Pitaevskii equation. As an example, we apply the formalism to the experimental results recently obtained in polariton microwires [E. Wertz, et al., Nature Phys. 6, 860 (2010)]. In the presence of a local non-resonant optical pump, a dynamic balance between spatially dependent relaxation and particle loss develops and excites a series of modes, roughly equally spaced in energy. Upon comparison, excellent agreement is found with the experimental data.

description: We investigate numerically the dynamics of two-dimensional Euler and ideal magnetohydrodynamics (MHD) flows in systems with a finite number of modes, up to $4096^2$, for which several quadratic invariants are preserved by the truncation and the statistical equilibria are known. Initial conditions are the Orszag-Tang vortex with a neutral X-point centered on a stagnation point of the velocity field in the large scales. In MHD, we observe that the total energy spectra at intermediate times and intermediate scales correspond to the interactions of eddies and waves, $E_T(k)\sim k^{-3/2}$. Moreover, no dissipative range is visible neither for Euler nor for MHD in two dimensions; in the former case, this may be linked to the existence of a vanishing turbulent viscosity whereas in MHD, the numerical resolution employed may be insufficient. When imposing a uniform magnetic field to the flow, we observe a lack of saturation of the formation of small scales together with a significant slowing-down of their equilibration, with however a cut-off independent partial thermalization being reached at intermediate scales.

description: We discuss how the main features of high-energy `soft' and `semihard' pp collisions may be described in terms of parton cascades and multi-Pomeron exchange. The interaction between Pomerons produces an effective infrared cutoff, k_{sat}, by the absorption of low k_t partons. This provides the possibility of extending the parton approach, used for `hard' processes, to also describe high-energy soft and semihard interactions. In particular, the presence of the cutoff k_{sat}, which increases with collider energy, means that the production and hadronization of minijets with p_t\gapproxeq k_{sat} are the main source of the soft secondaries. We propose several measurements which can be made at the LHC, that can further illuminate our understanding of the mechanism which drives the soft and semihard interactions. We show that the structure of Pomeron-Pomeron interactions may be studied in Double-Pomeron-Exchange processes and in the p_t distributions of secondaries near the edge of large rapidity gaps. The so-called `ridge effect' is another manifestation of the interaction of two partonic cascades.

End-of-life planning and care for patients with heart failure and their family members : why nurses and other health care professionals' knowledge, words, and feelings matter
Creators: name: Gibson, Jennifer Ann
Publisher: name: University of British Columbia

description: Heart failure (HF) is a progressive, chronic illness characterized by decompensation episodes and hospitalizations. Life expectancy is only 2 years following HF-related hospitalizations; when complicated by frailty and comorbidities, prognosis worsens. Compared to patients with malignancies, HF patients receive less end-of-life (EOL) planning and specialist palliative care. Patients with HF often die in hospitals, where prolonged dying, inadequately managed symptoms, and worsened suffering for patients/families are commonly reported. Hospital environments have been described as having influence on EOL planning and care. Thus, the purpose of this study was to understand how hospital environments influence healthcare professionals’ (HCPs) thinking about HF-EOL care and structure their approach and practices. The concept of structure was defined within a theoretical framework and informed the study design and research questions. Ethnographic methods and interpretive description guided data collection and analysis. A sample of twenty-two HCPs from various disciplines experienced in acute care and HF-EOL participated from two study sites; data were collected over 250 observation hours and through eighteen semi-structured individual interviews. Data analysis produced three main areas of findings: practice knowledge and notions of expertise; uses and meanings of EOL-related words and phrases; and, emotional and value-based dimensions. Participants commonly framed EOL planning and care as the work of clinical experts and framed expertise in relation to perceptions about the knowledge required for clinical practice in hospitals. Findings about HCPs’ knowledge also related to understandings and interpretations of frequently used EOL-related words such as “palliative.” These EOL-related words were used within interprofessional communications; however, differing interpretations existed. Findings about emotional and value-based dimensions of EOL planning and care work were identified. Emotions and values related to HCPs’ uses of strategies, such as avoiding particular words in order to manage emotion in EOL-related work. Discussion of the findings in this research highlight several implications including the need to more intentionally situate EOL planning and care for patients with HF-EOL as being within all professionals’ scopes of practice. The need to prioritize development of communication competencies for HCPs is also supported. Overall, this study adds new insights about how EOL practices are structured within hospital environments.

description: We study a ferromagnetic Ising model on random graphs with a power-law degree distribution and compute the thermodynamic limit of the pressure when the mean degree is finite (degree exponent $τ>2$), for which the random graph has a tree-like structure. For this, we adapt and simplify an analysis by Dembo and Montanari, which assumes finite variance degrees ($τ>3$). We further identify the thermodynamic limits of various physical quantities, such as the magnetization and the internal energy.

description: A novel lattice approach is presented for studying systems comprising a large number of interacting nonrelativistic fermions. The construction is ideally suited for numerical study of fermions near unitarity--a strongly coupled regime corresponding to the two-particle s-wave scattering phase shift delta_0 = pi/2. Such systems may be achieved experimentally with trapped atoms, and provide a starting point for an effective field theory description of nuclear physics. We discuss the construction of our lattice theory, which allows us to study systems of up to (but by no means limited to) 38 fermions with high accuracy and modest computational resources, and offer an overview of several applications of the technique. A more detailed discussion of applications and simulation results will be described in companion proceedings by A. N. N. and J-W. L.
