description: Most studies that examine CO2-neutral, or near CO2-neutral, power systems by using energy system models investigate Europe or the United States, while similar studies for other regions are rare. In this paper, we focus on the Middle East and North Africa (MENA), where weather conditions differ substantially from those in Europe. We use a green-field linear capacity expansion model with over-night investment to assess the effect on the system cost of (i) limiting/expanding the amount of land available for wind and solar farms, (ii) allowing for nuclear power and (iii) disallowing for international transmission. The assessment is done under three different cost regimes for solar PV and battery storage. First, we find that the amount of available land for wind and solar farms can have a significant impact on the system cost, with a cost increase of 0-50% as a result of reduced available land. Second, allowing for nuclear power has a minor effect in MENA, while it may decrease the system cost in Europe by up to 20%. In Europe, the effect on system cost from allowing for nuclear power is highly dependent on the PV and battery cost regime. Third, disallowing for international transmission increases the system cost by up to 25% in both Europe and MENA. The impacts on system cost from these three controversial and policy-relevant factors in a decarbonized power system thus play out differently, depending on (i) the region and (ii) uncertain future investment costs for solar PV and storage. We conclude that a renewable power system in MENA is likely to be less costly than one in Europe, irrespective of future uncertainties regarding investment cost for PV and batteries, and policies surrounding nuclear power, transmission, and land available for wind and solar farms.

description: The contribution of Delta(1232) to the piN -> pipiN reaction is examined by making use of the chiral reduction formula developed by Yamagishi and Zahed. The influence of the pi-Delta-Delta and rho-N-Delta interactions on this reaction, which has not been regarded as important so far, is considered for all channels with the initial pi^{+ -}p states. The total cross sections are calculated to tree level for the energy up to T_{pi}=400 MeV. Although the pi-Delta-Delta and rho-N-Delta interactions give a small effect on the pi^{+}p -> pi^{+}pi^{+}n, pi^{-}p -> pi^{+}pi^{-}n and pi^{-}p -> pi^{0}pi^{0}p channels, the pi^{+ -}p -> pi^{+ -}pi^{0}p channels are found to be sensitive to these interactions.

description: We performed neutron powder diffraction experiments on lithium imide Li2NH, and have proposed a revised crystal structure model. Li2NH has a face-centered cubic structure with a partially occupied hydrogen site. Of the possible crystal structure models that represent the obtained data, the model with F-43m symmetry having hydrogen atoms at the 16e site, in which only one hydrogen atom randomly occupies one of the four hydrogen positions around a nitrogen atom, is most probable. For this model, the distance between the nearest nitrogen and hydrogen atoms is 0.82(6)A, and the angle between H-N-H is 109.5deg., which are close to those of the lithium amide LiNH2, indicating that the structural circumstances around nitrogen and hydrogen are similar in Li2NH and LiNH2.

description: Two experiments examined the effects of morphine sulfate on feeding and adiposity in female rats. Experiment 1 demonstrated that administration of 40 mg/kg morphine produced a decrease in feeding and adiposity, with a greater reduction in adiposity following repeated morphine administration. Experiment 2 addressed whether morphine produced the decrease in adiposity or if the reduction in adiposity was a result of the morphine-induced decrease in feeding. Since the decrease in adiposity was independent of food intake, the mechanisms by which morphine and the endorphins may affect adiposity were discussed.

description: We solve the Wigner equation for massless spin-1/2 charged fermions near global equilibrium. The Wigner function can be obtained order by order in the power expansion of the vorticity and electromagnetic field. The Wigner function has been derived up to the second order from which the non-dissipative charge currents and the stress tensor can be obtained. The charge and energy densities and the pressure have contributions from the vorticity and electromagnetic field at the second order. The vector and axial Hall currents can be induced along the direction orthogonal to the vorticity and electromagnetic field at the second order. We also find that the trace anomaly emerges natually in renormalizing the stress tensor by including the quantum correction from the electromagnetic field.

Isotropisation of flat homogeneous universes with scalar fields

description: Starting from an anisotropic flat cosmological model(Bianchi type $I$), we show that conditions leading to isotropisation fall into 3 classes, respectively 1, 2, 3. We look for necessary conditions such that a Bianchi type $I$ model reaches a stable isotropic state due to the presence of several massive scalar fields minimally coupled to the metric with a perfect fluid for class 1 isotropisation. The conditions are written in terms of some functions $\ell$ of the scalar fields. Two types of theories are studied. The first one deals with scalar tensor theories resulting from extra-dimensions compactification, where the Brans-Dicke coupling functions only depend on their associated scalar fields. The second one is related to the presence of complex scalar fields. We give the metric and potential asymptotical behaviours originating from class 1 isotropisation. The results depend on the domination of the scalar field potential compared to the perfect fluid energy density. We give explicit examples showing that some hybrid inflation theories do not lead to isotropy contrary to some high-order theories, whereas the most common forms of complex scalar fields undergo a class 3 isotropisation, characterised by strong oscillations of the $\ell$ functions.

description: With a booming number of Type Ia supernovae (SNe Ia) discovered within a few days of their explosions, a fraction of SNe Ia that show luminosity excess in the early phase (early-excess SNe Ia) have been confirmed. In this article, we report early-phase observations of seven photometrically normal SNe Ia (six early detections and one deep non-detection limit) at the COSMOS field through a half-year transient survey as a part of the Hyper Suprime-Cam Subaru Strategic Program (HSC SSP). In particular, a blue light-curve excess was discovered for HSC17bmhk, a normal SN Ia with rise time longer than 18.8 days, during the first four days after the discovery. The blue early excess in optical wavelength can be explained not only by interactions with a non-degenerate companion or surrounding dense circumstellar matter but also radiation powered by radioactive decays of $^{56}$Ni at the surface of the SN ejecta. Given the growing evidence of the early-excess discoveries in normal SNe Ia that have longer rise times than the average and a similarity in the nature of the blue excess to a luminous SN Ia subclass, we infer that early excess discovered in HSC17bmhk and other normal SNe Ia are most likely attributed to radioactive $^{56}$Ni decay at the surface of the SN ejecta. In order to successfully identify normal SNe Ia with early excess similar to that of HSC17bmhk, early UV photometries or high-cadence blue-band surveys are necessary.

An investigation into UBC plastic cutlery and alternatives

description: UBC has committed its entire campus as an experiment in sustainability. This includes the community, land, assets, and utilities towards sustainability research, teaching, and learning. This commitment has been made in hopes of creating new opportunities to inspire dialogue and discoveries in sustainability. Sustainability is important in order to meet society’s needs without compromising the needs of future generations. The path of unsustainability can potentially lead to devastatingly negative consequences. One point that UBC is looking into being more sustainable is cutlery. All AMS Food Services use the same plastic cutlery at the moment. It is important that the current cutlery and alternatives be assessed in order to determine the most sustainable choice to maintain UBC’s commitment to sustainability. A plastic assessment is performed based on the Triple Bottom Line for cutlery. UBC’s current plastic cutlery is assessed for its sustainability performance in regards of the material it is composed of, recycling rates, cost, and social aspects. The same assessment is performed on other cutlery alternatives that include biodegradable cutlery, wooden cutlery, and cutlery brought from home. All of the assessments are then compared to each other to determine the most sustainable option. A social experiment to study the behavior of people recycling cutlery around campus is also performed. The result of the assessment is to keep the current BSI recyclable plastic cutlery as it is 100% recyclable and low in cost. The other alternatives have advantages and disadvantages compared to the BSI cutlery but none are significantly greater at the price range to replace it. UBC faces issues with their current system in regards to recycling the current cutlery. Not enough people dispose of their recyclables correctly due to insignificant signage as discovered through the social experiment. Solutions to this issue are more detailed signage or individual plastic recycling bins for different types of plastics.

description: Spectral sparsification is a technique that is used to reduce the number of non-zero entries in a positive semidefinite matrix with little changes to its spectrum. In particular, the main application of spectral sparsification is to construct sparse graphs whose spectra are close to a given dense graph. We study spectral sparsification under the assumption that the edges of a graph are allocated among sites which can communicate among each other. In this work we show that if a graph is allocated among several sites, the union of the spectral sparsifiers of each induced subgraph give us an spectral sparsifier of the original graph. In contrast to other works in the literature, we present precise computations of the approximation factor of the union of spectral sparsifiers and give an explicit calculation of the edge weights. Then we present an application of this result to data clustering in the Number-On-Forehead model of multiparty communication complexity when input data is allocated as a sunflower among sites in the party.

Subjects: subject: Cryptography and Security (cs.CR)

description: Intrusion Detection Systems (IDSs) can analyze network traffic for signs of attacks and intrusions. However, encrypted communication limits their visibility and sophisticated attackers additionally try to evade their detection. To overcome these limitations, we extend the scope of Network IDSs (NIDSs) with additional data from the hosts. For that, we propose the integrated open-source zeek-osquery platform that combines the Zeek IDS with the osquery host monitor. Our platform can collect, process, and correlate host and network data at large scale, e.g., to attribute network flows to processes and users. The platform can be flexibly extended with own detection scripts using already correlated, but also additional and dynamically retrieved host data. A distributed deployment enables it to scale with an arbitrary number of osquery hosts. Our evaluation results indicate that a single Zeek instance can manage more than 870 osquery hosts and can attribute more than 96% of TCP connections to host-side applications and users in real-time.

description: The relationships between the national security assistant and the president's political advisers have been crucial to the integration of foreign policy with domestic politics. It is often alleged that intrigue and power-struggle characterize the president's "inner-circle," sometimes to the detriment of policy coherence. This dissertation compares these relationships and their apparent policy consequences from 1947-1984. In addition to memoirs and periodicals, staff memoranda, oral histories, and meeting minutes at the Truman, Eisenhower, Kennedy, and Johnson presidential libraries, and the National Archives, were consulted. Clarification of written material was possible, and further information was collected, by conducting interviews with forty-three former senior White House staff members, some on numerous occasions. This dissertation identifies the extent to which political aides controlled the national security assistant's access to, and affected his influence on, the president; compares the rigidity with which presidents delineated domestic political and foreign policy responsibilities among the staff; and, describes the evolution of staff relations. Contrary to conventional belief these relationships have generally been cordial and cooperative although there has been periodic, issue-oriented friction. When there was incongruency between perceived diplomatic imperatives and domestic sentiment, friction sometimes resulted, especially when staff responsibilities were delineated rigidly. This friction, on occasion, caused the national security assistant to retain a tight hold on sensitive information, thereby preventing the other aides from injecting domestic political considerations during the decisionmaking process. Friction also tended to develop when the national security assistant was an extensive diplomatic operative and foreign policy spokesman. These two responsibilities made the assistant a potential lightning-rod for criticism about domestically unpopular foreign policies. Furthermore, when the assistant became popular through these activities, political aides sought to ensure that his popularity did not detract from the president's popularity. Therefore, although intra-White House relationships are normally cordial and cooperative, the conditions under which they tend to become contentious are relatively easy to identify. Friction among the staff can have a detrimental impact on foreign policy coherence.
Generalised Fayet-Iliopoulos terms in supergravity

Year: 2020
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: The U(1) vector multiplet theory with the Fayet-Iliopoulos (FI) term is one of the oldest and simplest models for spontaneously broken rigid supersymmetry. Lifting the FI term to supergravity requires gauged $R$-symmetry, as was first demonstrated in 1977 by Freedman within ${\cal N}=1$ supergravity. There exists an alternative to the standard FI mechanism, which is reviewed in this conference paper. It is obtained by replacing the FI model with a manifestly gauge-invariant action such that its functional form is determined by two arbitrary real functions of a single complex variable. One of these functions generates a superconformal kinetic term for the vector multiplet, while the other yields a generalised FI term. Coupling such a vector multiplet model to supergravity does not require gauging of the $R$-symmetry. These generalised FI terms are consistently defined for any off-shell formulation for ${\cal N}=1$ supergravity, and are compatible with a supersymmetric cosmological term.

description: A double exchange model with quenched disorder for conduction electrons is studied by field theoretical methods. By using a path integral formalism and replica techniques based on it, an ensemble-averaged spin wave dispersion of the localized spins is derived. It is shown that the spectrum of the spin wave has gaps at the multiple of the Fermi wavenumber of the conduction electrons in the presence of disorder, and hence, quenched disorder for electrons adds a striking effect to the dynamics of the localized spins. In the strong disorder limit, the present results suggest spin-glass like behavior due to the frustration of the exchange coupling.

We compare the WKB penetrability with a solution of the coupled-channels equations, and show that the WKB formula works well at energies well below the lowest adiabatic barrier. We also discuss the eigen-channel approach to a multi-channel tunneling, which may improve the performance of the WKB formula near and above the barrier.

description: Using Lamperti's relationship between Lévy processes and positive self-similar Markov processes (pssMp), we study the weak convergence of the law $\mathbb{P}_x$ of a pssMp starting at $x>0$, in the Skorohod space of càdlàg paths, when $x$ tends to 0. To do so, we first give conditions which allow us to construct a càdlàg Markov process $X^{(0)}$, starting from 0, which stays positive and verifies the scaling property. Then we establish necessary and sufficient conditions for the laws $\mathbb{P}_x$ to converge weakly to the law of $X^{(0)}$ as $x$ goes to 0. In particular, this answers a question raised by Lamperti [Z. Wahrsch. Verw. Gebiete 22 (1972) 205--225] about the Feller property for pssMp at $x=0$.

description: What will be if, given a pure stationary state on a compact hyperbolic surface, we start applying raising operator every $\hbar$ "adiabatic" second? It turns that during adiabatic time comparable to 1 wavefunction will change as a wave traveling with a finite speed (with respect to the adiabatic time), whereas the semiclassical measure of the system will undergo a controllable transformation. If adiabatic time goes to infinity then, by quantized Furstenberg Theorem, the system will become quantum uniquely ergodic. Thus, infinite ascension of a closed system leads to quantum chaos.

Observation of correlated-photon statistics using a single detector

description: We report experimental observations of correlated-photon statistics in the single-photon detection rate. The usual quantum interference in a two-photon polarization interferometer always accompanies a dip in the single detector counting rate, regardless of whether a dip or peak is seen in the coincidence rate. This effect is explained by taking into account all possible photon number states that reach the detector, rather than considering just the state post-selected by the coincidence measurement. We also report an interferometeric scheme in which the interference peak or dip in coincidence corresponds directly to a peak or dip in the single-photon detection rate.

description: M-theory effects prevent five-dimensional domain-wall and black-hole solutions from developing curvature singularities. While so far this analysis was performed for particular models, we now present a model-independent proof that these solutions do not have naked singularities as long as the Kahler moduli take values inside the extended Kahler cone. As a by-product we obtain information on the regularity of the Kahler-cone metric at boundaries of the Kahler cone and derive relations between the geometry of moduli space and space-time.

Entangled electron current through finite size normal-superconductor tunneling structures

description: We investigate theoretically the simultaneous tunneling of two electrons from a superconductor into a normal metal at low temperatures and voltages. Such an emission process is shown to be equivalent to the Andreev reflection of an incident hole. We obtain a local tunneling Hamiltonian that permits to investigate transport through interfaces of arbitrary geometry and potential barrier shapes. We prove that the bilinear momentum dependence of the low-energy tunneling matrix element translates into a real space Hamiltonian involving the normal derivatives of the electron fields in each electrode. The angular distribution of the electron current as it is emitted into the normal metal is analyzed for various experimental setups. We show that, in a full three-dimensional problem, the neglect of the momentum dependence of tunneling causes a violation of unitarity and leads to the wrong thermodynamic (broad interface) limit. More importantly for current research on quantum information devices, in the case of an interface made of two narrow tunneling contacts separated by a distance $r$, the assumption of momentum-independent hopping yields a nonlocally entangled electron current that decays with a prefactor proportional to $r^{-2}$ instead of the correct $r^{-4}$.

description: A linear regression algorithm is applied to a digital-supermode distributed Bragg reflector laser to optimise wavelength switching times. The algorithm uses the output of a digital coherent receiver as feedback to update the pre-emphasis weights applied to the laser section currents. This permits in-situ calculation without manual weight adjustments. The application of this optimiser to a representative subsection of channels indicates this commercially available laser can rapidly reconfigure over 6.05 THz, supporting 122 channels, in less than 10 ns.

Studying the Lyman-$α$ optical depth fluctuations at $z \sim 5.5$ using fast semi-numerical methods

description: We present a computationally efficient and fast semi-numerical technique for simulating the Lyman-$α$ (Ly$α$) absorption optical depth in presence of neutral hydrogen "islands" left over from reionization at redshifts $5 \lesssim z \lesssim 6$. The main inputs to the analysis are (i) a semi-numerical photon-conserving model of ionized regions during reionization (named SCRIPT) along with a prescription for simulating the shadowing by neutral islands and (ii) the fluctuating Gunn-Peterson approximation to model the Ly$α$ absorption. Our model is then used for simulating the large-scale fluctuations in the effective optical depth as observed along sight lines towards high$-z$ quasars. Our model is fully described by five parameters. By setting two of them to default values and varying the other three, we obtain the constraints on reionization history at $5 \lesssim z \lesssim 6$ as allowed by the data. We confirm that reionization is \emph{not} complete before $z \sim 5.6$ at $\gtrsim 2σ$ confidence, with the exact confidence limits depending on how the non-detections of the flux in the data are treated. We also confirm that the completion of reionization can be as late as $z \sim 5.2$. With further improvements in the model and with more sight lines at $z \sim 6$, we can take advantage of the computational efficiency of our analysis to obtain more stringent constraints on the ionization fraction at the tail-end of reionization.

description: This report looks to investigate and assess options for UBC to explore in regards to cigarette butt disposal on campus with respect to sustainable initiatives. Cigarette butts are a serious waste disposal problem that needs to be addressed. Investigative research was carried out on the available collection and disposal option currently used around the world. Additional proposed methods that are not currently being used were also explored. These options were then presented to the UBC student body in survey form to gauge response to initiatives proposals. These surveys in conjunction with a triple bottom line assessment were analyzed for the presentation of the recommended option for the adoption at UBC. The final combined collection and disposal recommendations for UBC is the adoption of enforced designated smoking areas with available collection receptacles. The collection receptacles facilitate easy collection of localized littering in addition to responsible deposition by smokers utilizing the area. 73.8% of students’ survey at UBC support designated smoking areas. Despite a recycling initiative available by TerraCycle, the collected cigarette butts will then be ultimately disposed of in the landfill UBC currently uses for regular waste. Landfills are heavily regulated and have groundwater contamination mitigation measures in place. The recycling initiative TerraCycle promotes the re-normalization of smoking, is subsidized by big tobacco companies, and was not able to be reached for information regarding their emissions and energy consumption.
