Logistics modeling of biomass supply chain in Ontario
Creators: name: Hamedani, Hamid Khaleghi
Publisher: name: University of British Columbia
Year: 2015

description: The overall goal of this research is to investigate the logistics of agricultural biomass in Ontario, Canada using the Integrated Biomass Supply Analysis and Logistics Model (IBSAL). The applicability of IBSAL is demonstrated through simulating three case studies. Case A is for the supply of corn stover to Ontario Power Generation (OPG) in Lambton. Case B concerns the supply of baled switchgrass from three farms to a greenhouse operation. Case C is for the supply of straw or switchgrass bales from 5 growing regions to Mushroom Producers Coop Inc. (MPCI). For Case A, five scenarios of delivering corn stover to the OPG power plant in Lambton Ontario are investigated: (1) base scenario, (2) central storage scenario, (3) direct scenario, (4) barge scenario, (5) railroad scenario. The net amount of annual biomass demand at the power plant is estimated to be 124,264 dry metric ton (Mg). For scenarios 1 to 5 the amount of biomass required to be harvested is respectively 160123, 155730, 151141,172480, and 170686 Mg per year. Also the total cost estimated to be respectively $37/Mg, $49/Mg, $33/Mg, $94/Mg, and $81/Mg. For Case B, the annual heating demand of a greenhouse located on southwestern Ontario near Lake Huron is calculated as 20,730 GJ/year. Roughly 2,200 Mg of switchgrass is required. Cost, energy consumption and carbon emission associated with the supply chain are $66/Mg, 151.3 MJ/Mg and 10.4 kg CO₂/Mg, respectively. The dry matter loss is calculated to be 805 Mg. For Case C, the following scenarios are modeled: (1) Base case scenario, (2) Straw location scenario, (3) Straw field to MPCI, (4) Switchgrass location scenario. Delivery costs of the first scenario vary in the range of $50-69/Mg. In the second scenario, the total average costs were $74/Mg, $68/Mg, and $70/Mg for the storage on gravel, storage on gravel with pad and protected under shed. Scenario 3 showed how sorted and unsorted bales affect the cost. The forth scenario the average total costs were reported to be $106.7/Mg, $91.4/Mg, and $90.8/Mg respectively for storage on the gravel pad on the gravel pad and protected under shed.

description: Each and every energy dependent partial-wave analysis is parameterizing the pole positions in a procedure defined by the way how the continuous energy dependence is implemented. These pole positions are, henceforth, inherently model dependent. To reduce this model dependence, we use only one, coupled-channel, unitary, fully analytic method based on the isobar approximation to extract the pole positions from the each available member of the worldwide collection of partial wave amplitudes which are understood as nothing more but a good energy dependent representation of genuine experimental numbers assembled in a form of partial-wave data. In that way, the model dependence related to the different assumptions on the analytic form of the partial-wave amplitudes is avoided, and the true confidence limit for the existence of a particular resonant state, at least in one model, is established. The way how the method works, and first results are demonstrated for the S11 partial wave.

Evidence for the White Dwarf Nature of Mira B

description: The nature of the accreting companion to Mira --- the prototypical pulsating asymptotic giant branch star --- has been a matter of debate for more than 25 years. Here we use a quantitative analysis of the rapid optical brightness variations from this companion, Mira B, which we observed with the Nickel telescope at Lick Observatory, to show that it is a white dwarf (WD). The amplitude of aperiodic optical variations on time scales of minutes to tens of minutes (approximately 0.2 mag) is consistent with that of accreting WDs in cataclysmic variables on these same time scales. It is significantly greater than that expected from an accreting main-sequence star. With Mira B identified as a WD, its ultraviolet (UV) and optical luminosities, along with constraints on the WD effective temperature from the UV, indicate that it accretes at ~1e-10 solar masses per year. We do not find any evidence that the accretion rate is higher than predicted by Bondi-Hoyle theory. The accretion rate is high enough, however, to explain the weak X-ray emission, since the accretion-disk boundary layer around a low-mass WD accreting at this rate is likely to be optically thick and therefore to emit primarily in the far or extreme UV. Furthermore, the finding that Mira B is a WD means that it has experienced, and will continue to experience nova explosions, roughly every million years. It also highlights the similarity between Mira AB and other jet-producing symbiotic binaries such as R Aquarii, CH Cygni, and MWC 560, and therefore raises the possibility that Mira B launched the recently discovered bipolar streams from this system.

description: In this article, a survey of several important equilibrium concepts for decentralized networks is presented. The term decentralized is used here to refer to scenarios where decisions (e.g., choosing a power allocation policy) are taken autonomously by devices interacting with each other (e.g., through mutual interference). The iterative long-term interaction is characterized by stable points of the wireless network called equilibria. The interest in these equilibria stems from the relevance of network stability and the fact that they can be achieved by letting radio devices to repeatedly interact over time. To achieve these equilibria, several learning techniques, namely, the best response dynamics, fictitious play, smoothed fictitious play, reinforcement learning algorithms, and regret matching, are discussed in terms of information requirements and convergence properties. Most of the notions introduced here, for both equilibria and learning schemes, are illustrated by a simple case study, namely, an interference channel with two transmitter-receiver pairs.

description: A two miniband model for electron transport in semiconductor superlattices that includes scattering and interminiband tunnelling is proposed. The model is formulated in terms of Wigner functions in a basis spanned by Pauli matrices, includes electron-electron scattering in the Hartree approximation and modified Bhatnagar-Gross-Krook collision tems. For strong applied fields, balance equations for the electric field and the miniband populations are derived using a Chapman-Enskog perturbation technique. These equations are then solved numerically for a dc voltage biased superlattice. Results include self-sustained current oscillations due to repeated nucleation of electric field pulses at the injecting contact region and their motion towards the collector. Numerical reconstruction of the Wigner functions shows that the miniband with higher energy is empty during most of the oscillation period: it becomes populated only when the local electric field (corresponding to the passing pulse) is sufficiently large to trigger resonant tunneling.

The monkey and crocodile story in Japan : the presence of an ancient Indian tale among early Japanese narratives
Creators: name: Marsh, Elizabeth
Publisher: name: University of British Columbia
Year: 2015

description: This thesis examines the presence of early Indian narrative elements in Japan through an analysis of tale collections and regional Japanese folklore. Focusing on the reception of the widely distributed monkey and crocodile story, the present study aims to elucidate the role of Indian tales within Japan, and will serve to demonstrate the position of Japanese folklore among globally present motifs and tale types. The project discusses literary and oral forms of the story, examining variants among the Indian Jātakas (ca. 3rd c. BCE – 5th c. CE) and Pañcatantra (ca. 300 CE), the twelfth century Konjaku monogatarishū, and nineteen oral retellings recorded from across Japan. Elements characteristic of the three primary literary versions are identified, while also recording transformations, additions, or omissions of thematic elements, as well as core motifs that have remained consistent across all known stories. This analysis demonstrates that Japanese variants of the tale were not drawn linearly from a single Buddhist text, but instead represent a fusion of themes from across various religious and cultural contexts. The present study also provides some explanation as to the extensive dissemination of the story within Japan, identifying characteristics of the tale that facilitated its lasting and widespread promulgation. The study examines similarly themed myths and legends from the indigenous Japanese tradition that provided the foundations for its assimilation into the existing storytelling culture and the integration of characteristically Japanese motifs into the core framework of this imported narrative.

description: We investigated the plasmonic modes in a two-dimensional quasicrystalline array of metal nanoparticles. The polarization of the modes is in the array plane. A simplified eigen-decomposition method is presented with the help of rotational symmetry. Two kinds of anti-phase ring modes with radial and tangential polarizations are of highest spatial localizations among all of plasmonic modes. For the leaky characteristic of the anti-phase ring modes, the highest fidelity mode is found to be tangential polarized mode in the quasicrystal array, whereas normal-to-plane polarized mode in the solo ring. The leaky characteristics and spatial localizations of other plasmonic modes are also studied, for example, collective vortex mode that may be potentially useful to form negative responses in plasmonic device, and collective radial mode that may be used to generate light sources with radial polarizations.

description: We present an analysis of the diffuse hard X-ray emission in the core of the young massive Galactic cluster Westerlund 1 based on a 48 ks XMM-Newton observation. Chandra results for the diffuse X-ray emission have indicated a soft thermal component together with a hard component that could be either thermal or non-thermal. We seek to resolve this ambiguity regarding the hard component exploiting the higher sensitivity of XMM-Newton to diffuse emission. Our new X-ray spectra from the central (2' radius) diffuse emission are found to exhibit He-like Fe 6.7 keV line emission, demonstrating that the hard emission in the cluster core is predominantly thermal in origin. Potential sources of this hard component are reviewed, namely an unresolved Pre-Main Sequence population, a thermalized cluster wind and Supernova Remnants interacting with stellar winds. We find that the thermalized cluster wind likely contributes the majority of the hard emission with some contribution from the Pre-Main Sequence population. It is unlikely that Supernova Remnants are contributing significantly to the Wd1 diffuse emission at the current epoch.

Mottness Collapse and T-linear Resistivity in Cuprate Superconductors

Publisher: name: arXiv
Year: 2010
Subjects: subject: Strongly Correlated Electrons (cond-mat.str-el)
subject: FOS: Physical sciences

description: Central to the normal state of cuprate high-temperature superconductors is the collapse of the pseudogap, briefly reviewed here, at a critical point and the subsequent onset of the strange-metal characterized by a resistivity that scales linearly with temperature. A possible clue to the resolution of this problem is the inter-relation between two facts: 1) A robust theory of T-linear resistivity resulting from quantum criticality requires an additional length scale outside the standard 1-parameter scaling scenario and 2) breaking the Landau correspondence between the Fermi gas and an interacting system with short-range repulsions requires non-fermionic degrees. We show that a low-energy theory of the Hubbard model which correctly incorporates dynamical spectral weight transfer has the extra degrees of freedom needed to describe this physics. The degrees of freedom that mix into the lower band as a result of dynamical spectral weight transfer are shown to either decouple beyond a critical doping, thereby signaling Mottness collapse or unbind above a critical temperature yielding strange metal behaviour characterised by $T-$linear resistivity.

description: We study the impact of nonrenormalizable operators in flipped SU(5) that can generate a large mu term, R-parity violation, and rapid proton decay. While our motivation is to determine whether F-theory can naturally realize flipped SU(5), this analysis is general and leads to a characterization of symmetries capable of controlling such operators and should be independent of F-theory. We then discuss some specific implications for F-theory model building, where a significant mu problem is unavoidable. Finally, we mention previously noted difficulties associated to engineering GUT-Higgs fields in F-theory, suggest a direct engineering of SU(5) \times U(1)_χ as an alternative, and present a sample construction of this type.

description: The unprecedented coronavirus disease 2019 (COVID-19) pandemic, caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), is a serious threat to global public health. Development of effective therapies against SARS-CoV-2 is urgently needed. Here, we evaluated the antiviral activity of a remdesivir parent nucleotide analog, GS441524, which targets the coronavirus RNA-dependent RNA polymerase enzyme, and a feline coronavirus prodrug, GC376, which targets its main protease, using a mouse-adapted SARS-CoV-2 infected mouse model. Our results showed that GS441524 effectively blocked the proliferation of SARS-CoV-2 in the mouse upper and lower respiratory tracts via combined intranasal (i.n.) and intramuscular (i.m.) treatment. However, the ability of high-dose GC376 (i.m. or i.n. and i.m.) was weaker than GS441524. Notably, low-dose combined application of GS441524 with GC376 could effectively protect mice against SARS-CoV-2 infection via i.n. or i.n. and i.m. treatment. Moreover, we found that the pharmacokinetic properties of GS441524 is better than GC376, and combined application of GC376 and GS441524 had a synergistic effect. Our findings support the further evaluation of the combined application of GC376 and GS441524 in future clinical studies.

description: The purpose of a wireless sensor network (WSN) is to provide the users with access to the information of interest from data gathered by spatially distributed sensors. Generally the users require only certain aggregate functions of this distributed data. Computation of this aggregate data under the end-to-end information flow paradigm by communicating all the relevant data to a central collector node is a highly inefficient solution for this purpose. An alternative proposition is to perform in-network computation. This, however, raises questions such as: what is the optimal way to compute an aggregate function from a set of statistically correlated values stored in different nodes; what is the security of such aggregation as the results sent by a compromised or faulty node in the network can adversely affect the accuracy of the computed result. In this paper, we have presented an energy-efficient aggregation algorithm for WSNs that is secure and robust against malicious insider attack by any compromised or faulty node in the network. In contrast to the traditional snapshot aggregation approach in WSNs, a node in the proposed algorithm instead of unicasting its sensed information to its parent node, broadcasts its estimate to all its neighbors. This makes the system more fault-tolerant and increase the information availability in the network. The simulations conducted on the proposed algorithm have produced results that demonstrate its effectiveness.

description: Compton scattering plays an important role in various astrophysical objects such as accreting black holes and neutron stars, pulsars, and relativistic jets, clusters of galaxies as well as the early Universe. In most of the calculations it is assumed that the electrons have isotropic angular distribution in some frame. However, there are situations where the anisotropy may be significant due to the bulk motions, or anisotropic cooling by synchrotron radiation, or anisotropic source of seed soft photons. We develop here an analytical theory of Compton scattering by anisotropic distribution of electrons that can simplify significantly the calculations. Assuming that the electron angular distribution can be represented by a second order polynomial over cosine of some angle (dipole and quadrupole anisotropy), we integrate the exact Klein-Nishina cross-section over the angles. Exact analytical and approximate formulae valid for any photon and electron energies are derived for the redistribution functions describing Compton scattering of photons with arbitrary angular distribution by anisotropic electrons. The analytical expressions for the corresponding photon scattering cross-section on such electrons as well as the mean energy of scattered photons, its dispersion and radiation pressure force are also derived. We applied the developed formalism to the accurate calculations of the thermal and kinematic Sunyaev-Zeldovich effects for arbitrary electron distributions.

description: Traditional approach of providing network security has been to borrow tools and mechanisms from cryptography. However, the conventional view of security based on cryptography alone is not sufficient for the defending against unique and novel types of misbehavior exhibited by nodes encountered in wireless communication networks. Reputation-based frameworks where nodes maintain reputation of other nodes and use it to evaluate their trustworthiness are deployed to provide scalable, diverse and a generalized approach for countering different types of misbehavior resulting form malicious and selfish nodes in these networks. In this paper, we present a comprehensive discussion on reputation and trust-based systems for wireless communication networks. Different classes of reputation system are described along with their unique characteristics and working principles. A number of currently used reputation systems are critically reviewed and compared with respect to their effectiveness and efficiency of performance. Some open problems in the area of reputation and trust-based system within the domain of wireless communication networks are also discussed.

description: The progression of game theory from classical to evolutionary and spatial games provided a powerful means to study cooperation, and enabled a better understanding of general cooperation-promoting mechanisms. However, current standard models assume that at any given point players must choose either cooperation or defection, meaning that regardless of the spatial structure in which they exist, they cannot differentiate between their neighbours and adjust their behaviour accordingly. This is at odds with interactions among organisms in nature who are well capable of behaving differently towards different members of their communities. We account for this natural fact by introducing a new type of players—dubbed link players—who can adjust their behaviour to each individual neighbour. This is in contrast to more common node players whose behaviour affects all neighbours in the same way. We proceed to study cooperation in pure and mixed populations, showing that cooperation peaks at moderately low densities of link players. In such conditions, players naturally specialize in different roles. Node players tend to be either cooperators or defectors, while link players form social insulation between cooperative and defecting clusters by acting both as cooperators and defectors. Such fairly complex processes emerging from a simple model reflect some of the complexities observed in experimental studies on social behaviour in microbes and pave a way for the development of richer game models.
Dopamine and PDF signaling modulate habituation to repeated activation of a polymodal nociceptor in caenorhabditis elegans
Creators: name: Ardiel, Evan
Publisher: name: University of British Columbia
Year: 2015

description: Habituation is a highly conserved phenomenon that remains poorly understood at the molecular level. Invertebrate model systems, like C. elegans, can be a powerful tool for understanding this fundamental process. To expand our knowledge of habituation I developed a high-throughput learning assay using real-time computer vision software for behavioral tracking and optogenetics for stimulation of a C. elegans polymodal nociceptor pair, ASHL and ASHR. These cells are especially interesting in the context of habituation because of the diversity and salience of the stimuli they detect. Photoactivation of ASH promoted backward locomotion and persistent stimulation altered the magnitude of this response in a manner consistent with the key behavioral characteristics of habituation. The decrement in reversal duration was readily reversed by a dishabituating stimulus, in this case non-localized mechanosensory input detected by the touch receptor neurons. In addition to altering the response properties, repeated ASH activation suppressed spontaneous reversals and accelerated forward movement. Food and dopamine signaling (bas-1, cat-4, cat-2, trp-4) promoted responding to persistent ASH activation and I identified the D1-like dopamine receptor, DOP-4, as the key mediator. Neuropeptide synthesis mutants (egl-3 and egl-21) displayed impaired plasticity for a variety of behavioral metrics, prompting me to perform an RNAi screen targeting neuropeptide receptors. From this screen, I implicated pigment dispersing factor (PDF) signaling in habituation of response latency and duration. Failure to avoid some stimuli detected by ASH could be fatal for C. elegans, so why do the reversal responses habituate? My data indicate that habituation is part of a strategy to promote dispersal.

description: The link between the shaping of bipolar planetary nebulae and their central stars is still poorly understood. The kinematics and shaping of the multipolar nebula M 1-75 are hereby investigated, and the location and nature of its central star are briefly discussed. Fabry-Perot data from GHaFAS on the WHT sampling the Doppler shift of the [N II] 658.3 nm line are used to study the dynamics of the nebula, by means of a detailed 3-D spatio-kinematical model. Multi-wavelength images and spectra from the WFC and IDS on the INT, and from ACAM on the WHT, allowed us to constrain the parameters of the central star. The two pairs of lobes, angularly separated by ~22 degrees, were ejected simultaneously approx. ~3500-5000 years ago, at the adopted distance range from 3.5 to 5.0 kpc. The larger lobes show evidence of a slight degree of point symmetry. The shaping of the nebula could be explained by wind interaction in a system consisting of a post-AGB star surrounded by a disc warped by radiative instabilities. This requires the system to be a close binary or a single star which engulfed a planet as it died. On the other hand, we present broad- and narrow-band images and a low S/N optical spectrum of the highly-reddened, previously unnoticed star which is likely the nebular progenitor. Its estimated V-I colour allows us to derive a rough estimate of the parameters and nature of the central star.

A phenomenological analysis of mid-life women’s challenges in their relationships with food
Creators: name: Palandra, Ashley Lauren

description: To date, the vast majority of research exploring disordered eating (DE) and eating disorders (EDs) among women has been conducted with younger populations. However, a small but growing body of literature has demonstrated the increasing prevalence of eating problems among mid-life women. Despite recent scholarly interest in this area, very little is known about mid-life women’s experiences of living with eating challenges, and the meanings they attribute to this phenomenon. The current study was designed to address this gap in the literature, using a hermeneutic phenomenological methodology (van Manen, 1990). The research question that guided this inquiry was: “What is the meaning and experience of having a problematic relationship with food for women in mid-life?” In-depth, audio-recorded qualitative research interviews were conducted with nine women between the ages of 41 and 65. Interviews were transcribed verbatim, and a thematic analysis consistent with van Manen’s (1990) hermeneutic phenomenological approach was conducted. Six common themes emerged from the participants’ experiences of having a problematic relationship with food in mid-life: (1) Sense of Food as Comfort and a Means of Coping, (2) Sense of Guilt and Shame, (3) Sense of Needing Control, (4) Sense of Food and Eating as Addiction, (5) Sense of Pressure to Conform, and (6) Sense of Loss of Social Power and Visibility. The study findings are discussed within the context of the extant literature exploring EDs among younger and mid-life women, and similarities and differences between these demographic groups are explored. Finally, implications of the study findings for theory, research, and clinical practice are discussed.

description: We report the formulation of nanoassemblies (NAs) comprising C225 conjugates Au-PFH-NAs (C-Au-PFH-NAs) for low-intensity focused ultrasound diagnosis ablation of thyroid cancer. C-Au-PFH-NAs showed excellent stability in water, phosphate-buffered saline (PBS), and 20% rat serum. Transmission electron microscopy (TEM) images also revealed the effective construction of C-Au-PFH-NAs as common spherical assemblies. The incubation of C625 thyroid carcinoma with C-Au-PFH-NAs triggers apoptosis, as confirmed by flow cytometry analysis. The C-Au-PFH-NAs exhibited antitumour efficacy in human thyroid carcinoma xenografts, where histopathological results further confirmed these outcomes. Furthermore, we were able to use low-intensity focused ultrasound diagnosis imaging (LIFUS) to examine the efficiency of C-Au-PFH-NAs in thyroid carcinoma in vivo. These findings clearly show that the use of LIFUS agents with high-performance imaging in different therapeutic settings will have extensive potential for future biomedical applications.
Comment on "Effect of entanglement on the decay dynamics of a pair of H(2p) atoms due to spontaneous emission"

description: Tanabe et al (Phys. Rev. A {\bf 82} 040101(R) 2010) have experimentally demonstrated that the emission properties of unstable atoms in entangled and product states are different. The authors define an apparent decay time as a fitting parameter which falls below the lifetime of the single atom for entangled pairs. We argue that their results about coincidence time spectra are correct, but those concerning lifetimes cannot be considered conclusive because they assume the emission of photons by the two atoms to be independent processes, a doubtful hypothesis for entangled states. We suggest an improved evaluation of the lifetimes based on a rigorous approach, which demands some modifications of the experimental procedure.

description: We present an experimental and theoretical study of atom-molecule collisions in a mixture of cold, trapped atomic nitrogen and NH molecules at a temperature of $\sim 600$~mK. We measure a small N+NH trap loss rate coefficient of $k^{(\mathrm{N+NH})}_\mathrm{loss} = 8(4) \times 10^{-13}$~cm$^{3}$s$^{-1}$. Accurate quantum scattering calculations based on {\it ab initio} interaction potentials are in agreement with experiment and indicate the magnetic dipole interaction to be the dominant loss mechanism. Our theory further indicates the ratio of N+NH elastic to inelastic collisions remains large ($>100$) into the mK regime.

description: The interaction of open and closed field lines at coronal hole boundaries is widely accepted to be due to interchange magnetic reconnection. To date, it is unclear how the boundaries vary on short timescales and at what velocity this occurs. Here, we describe an automated boundary tracking method used to determine coronal hole boundary displacements on short timescales. The bound- ary displacements were found to be isotropic and to have typical expansion/contraction speeds of \leq2 km s^-1, which indicate magnetic reconnection rates of \leq 3 \times 10^-3. The observed displacements were used in conjunction with the interchange reconnection model to derive typical diffusion coeffi- cients of \leq 3 \times 10^13 cm^2 s^-1. These results are consistent with an interchange reconnection process in the low corona driven by the random granular motion of open and closed fields in the photosphere.

description: Holographic currents and their associated Ward identities are derived in the framework of gravity/gauge duality. Holographic improvements of the energy-momentum tensor and R-symmetry current which are consistent with the Ward identities are displayed. The effects of specific string loop corrections to the bulk action are included as four derivative effective lagrangian terms and their contributions to the trace and R-symmetry anomalies of the boundary theory are determined. As an example, the construction is applied to the N=2 conformal supergravity which is taken to be dual to a boundary SU(N)xSU(N), N=1 superconformal field theory.

description: First measurements of the decays of the three $χ_{cJ}$ states to $p\bar{p}K^{+}K^{-}$ final states are presented. Intermediate $ϕ\to K^{+}K^{-}$ and $Λ(1520)\to pK^{-}$ resonance states are observed, and branching fractions for $χ_{cJ}\to \bar{p}K^{+}Λ(1520)$, $Λ(1520) \barΛ(1520)$, and $ϕp\bar{p}$ are reported. We also measure branching fractions for direct $χ_{cJ}\to p\bar{p} K^{+}K^{-}$ decays. These are first observations of $χ_{cJ}$ decays to unstable baryon resonances and provide useful information about the $χ_{cJ}$ states. The experiment uses samples of $χ_{cJ}$ mesons produced via radiative transitions from 106 million $ψ^{\prime}$ mesons collected in the BESIII detector at the BEPCII $e^+e^-$ collider.

description: Difficulty of learning calculus was faced by many students in higher secondary schools because the teaching was teacher centered and usually focused on explaining the notations and symbols used in calculus. Even after passing the examination, the students were not able to relate what they have learned in classroom in real life situations. With change of time the new approaches to teach calculus must be adopted so that what students learned in the classroom ac be also apply in real life situations. A few approaches used in teaching calculus that focus specifically on differential and integral calculus are reviewed: algebraic, graphical, contextual or realistic, and computer-assisted approaches.
