description: (Abridged) Classical novae (CNe) have recently been reported to represent the major class of supersoft X-ray sources (SSSs) in the central region of our neighbour galaxy M 31. We carried out a dedicated monitoring of the M 31 central region with XMM-Newton and Chandra in order to find SSS counterparts of CNe, determine the duration of their SSS phase and derive physical outburst parameters. We systematically searched our data for X-ray counterparts of CNe and determined their X-ray light curves and spectral properties. Additionally, we determined luminosity upper limits for all novae from previous studies which are not detected anymore and for all CNe in our field of view with optical outbursts between May 2005 and March 2007. We detected eight X-ray counterparts of CNe in M 31, four of which were not previously known. Seven sources can be classified as SSSs, one is a candidate SSS. Two SSSs are still visible more than nine years after the nova outburst, whereas two other nova counterparts show a short SSS phase of less than 150 days. Of the latter sources, M31N 2006-04a exhibits a short-time variable X-ray light curve with an apparent period of (1.6+-0.3) h. This periodicity could indicate the binary period of the system. From the 14 SSS nova counterparts known from previous studies, ten are not detected anymore. Additionally, we found four SSSs in our XMM-Newton data without a nova counterpart, one of which is a new source. Out of eleven SSSs detected in our monitoring, seven are counterparts of CNe. We therefore confirm the earlier finding that CNe are the major class of SSSs in the central region of M 31. We use the measured SSS turn-on and turn-off times to estimate the mass ejected in the nova outburst and the mass burned on the white dwarf. Classical novae with short SSS phases seem to be an important contributor to the overall population.

description: During the war, the Tsarist government imported large groups of Chinese to the Russian Empire to work behind the front lines. Despite their important contribution to the Russian war effort, Chinese workers’ war experiences remain largely forgotten, often overshadowed by their participation in the Russian Civil War (1917-1921). This article examines the process of workers’ recruitment in China and their employment conditions in wartime Russia.

description: PTF09dav is a peculiar subluminous type Ia supernova (SN) discovered by the Palomar Transient Factory (PTF). Spectroscopically, it appears superficially similar to the class of subluminous SN1991bg-like SNe, but it has several unusual features which make it stand out from this population. Its peak luminosity is fainter than any previously discovered SN1991bg-like SN Ia (M_B -15.5), but without the unusually red optical colors expected if the faint luminosity were due to extinction. The photospheric optical spectra have very unusual strong lines of Sc II and Mg I, with possible Sr II, together with stronger than average Ti II and low velocities of ~6000 km/s. The host galaxy of PTF09dav is ambiguous. The SN lies either on the extreme outskirts (~41kpc) of a spiral galaxy, or in an very faint (M_R>-12.8) dwarf galaxy, unlike other 1991bg-like SNe which are invariably associated with massive, old stellar populations. PTF09dav is also an outlier on the light-curve-width--luminosity and color--luminosity relations derived for other sub-luminous SNe Ia. The inferred 56Ni mass is small (0.019+/-0.003Msun), as is the estimated ejecta mass of 0.36Msun. Taken together, these properties make PTF09dav a remarkable event. We discuss various physical models that could explain PTF09dav. Helium shell detonation or deflagration on the surface of a CO white-dwarf can explain some of the features of PTF09dav, including the presence of Sc and the low photospheric velocities, but the observed Si and Mg are not predicted to be very abundant in these models. We conclude that no single model is currently capable of explaining all of the observed signatures of PTF09dav.

Parabolization and structural integrity of side bulb applied platform supply vessel hull form
Creators: name: Deli, Ozgur
Publisher: name: University of British Columbia
Year: 2014

description: The parabolization work is a hull-optimization method for minimizing total resistance of ship by using numerical and experimental methods. Ship total hydrodynamic resistance is a sum of frictional resistance, form resistance and wave resistance. The form resistance is a fraction of frictional resistance while the wave resistance dominates as speed increases. It becomes clear to turn toward minimizing wave resistance for hull-form optimization studies regarding increased speeds. In 2002, Calisal et al. reported a 10% decrease in effective horse power at Fn = 0.275 for a coaster tanker. The objective was to attain a beneficial wave-resistance reduction over a moderate to relatively high operating speed range. The parabolization work was done by a computer software that expends the form at waterline and replaces the conventional parallel middle-body section with parabolic side bulbs. This study was made for a oil platform supply vessel (PSV)and studies an improved , new hull form. The form is a new “retrofit” , for the present parent hull form, increasing the vessel’s beam up to 5% and its displacement accordingly. In this thesis new scantling was calculated for the parabolized hull. The structural analysis and design for the parent and “retrofit” hull forms were done, using the rules and guidelines of the American Bureau of Shipping (ABS). The final part of the thesis provides a cost payback analysis of the parabolized PSV. A fuel savings of 280,000 liters/year provides $235,000.00 per year saving based on a 5.88% drop in resistance . The investment for the construction of an amidships bulb is estimated at $161,000. The payback period for the construction of an amidships bulb is estimated to be nine to seventeen months, with different ship type factors. In addition resistance reduction saves 753,900 kg of CO2 and 134,100 kg of NOx . The parabolization cost analysis is seen in three parts. First, the investment cost of the side bulb. Second, the savings in fuel cost representing the savings in the running cost and the change in the investment cost of propulsion machinery of the vessel and thirdly, the environmental savings by low CO2 and NOx emission.

description: The stationary problem of light interaction with a dense collection of two-level atoms embedded in a dielectric is treated semiclassically. The effect of dielectric absorption on the phenomenon of intrinsic optical bistability is discussed in terms of the complex local-field enhancement factor. The calculations accounting propagation effects (nonlocal regime) show that even low dielectric absorption results in elimination of response instabilities.

description: For a simple graph $G$ with $n$ vertices and $m$ edges, the first Zagreb index and the second Zagreb index are defined as $M_1(G)=\sum_{v\in V}d(v)^2 $ and $M_2(G)=\sum_{uv\in E}d(u)d(v)$. In \cite{VGFAD}, it was shown that if a connected graph $G$ has maximal degree 4, then $G$ satisfies $M_1(G)/n = M_2(G)/m$ (also known as the Zagreb indices equality) if and only if $G$ is regular or biregular of class 1 (a biregular graph whose no two vertices of same degree are adjacent). There, it was also shown that there exist infinitely many connected graphs of maximal degree $Δ= 5$ that are neither regular nor biregular of class 1 which satisfy the Zagreb indices equality. Here, we generalize that result by showing that there exist infinitely many connected graphs of maximal degree $Δ\geq 5$ that are neither regular nor biregular graphs of class 1 which satisfy the Zagreb indices equality. We also consider when the above equality holds when the degrees of vertices of a given graph are in a prescribed interval of integers.

Material girls : examining the effects of subject/object relationships on the protagonists of Neil Gaiman's Coraline and Hiromi Goto's Half World
Creators: name: Kesanakurthy, Yashaswi
Publisher: name: University of British Columbia
Year: 2014

description: This study uses thing theory as a focal lens to examine the way subject/object relationships are portrayed within two fantasy novels— Neil Gaiman’s Coraline and Hiromi Goto’s Half World— that have elements of horror in them. It takes into consideration the tropes and stereotypes present within dark stories for children and uses thing theory to look at how subjects and objects are introduced to one another within a horror setting and, consequently, how they transform each other through either use or misuse. This allows for a fuller understanding of how subjects and objects transgress and mutate within the horror genre. It provides an alternative direction from which to approach the analysis of character development by understanding the ways in which child protagonists are transformed by objects and how they, in turn, can manipulate things and situations to shift the balance of power in their favour. The findings provide an alternative approach to the further study of gender representations and cultural identities in horror fiction for children and young adults.

Here we report on a comparison of a CBT with a high accuracy realization of the PLTS-2000 temperature scale in the range from 0.008 K to 0.65 K. An overall agreement of about 1% was found for temperatures above 0.25 K. For lower temperatures increasing differences are caused by thermalization problems which are accounted for by numerical calculations based on electron-phonon decoupling.

Measuring '%Ndfa' and 'Biological Nitrogen Fixation'

Year: 2021

description: Measuring biological nitrogen fixation (BNF) is an important agronomic and agroecological trait of legumes. The trait is often neglected yet it is an indicator of crop performance with respect to a plant’s capacity to derive nitrogen from air via BNF. This process is mediated by soil bacteria, collectively termed rhizobia, that form a symbiosis with the legume. The rhizobia are contained within legume root nodules and here in the nodule core (a microaerophilic environment), the rhizobia fix largely inert atmospheric di-nitrogen gas into biologically useful nitrogen compounds. These compounds are shared with the host plant in exchange for energy in the form of photosynthate. The process of measuring BNF comprises two stages.

A compactness result for Landau state in thin-film micromagnetics

Publisher: name: arXiv
Year: 2010
Subjects: subject: Analysis of PDEs (math.AP)
subject: FOS: Mathematics

description: We deal with a nonconvex and nonlocal variational problem coming from thin-film micromagnetics. It consists in a free-energy functional depending on two small parameters $\eps$ and $η$ and defined over $S^2-$vector fields $m$ that are tangent at the boundary of a two-dimensional domain $Ω$. We are interested in the behavior of minimizers as $\eps, η\to 0$. The minimizers tend to be in-plane away from a region of length scale $\eps$ (generically, an interior vortex ball or two boundary vortex balls) and of vanishing divergence, so that $S^1-$transition layers of length scale $η$ (Néel walls) are enforced by the boundary condition. We first prove an upper bound for the minimal energy that corresponds to the cost of a vortex and the configuration of Néel walls associated to the viscosity solution, so-called Landau state. Our main result concerns the compactness of vector fields $m_{\eps, η}$ of energies close to the Landau state in the regime where a vortex is energetically more expensive than a Néel wall. Our method uses techniques developed for the Ginzburg-Landau type problems for the concentration of energy on vortex balls, together with an approximation argument of $S^2-$vector fields by $S^1-$vector fields away from the vortex balls.

The Future of Indirect Evidence

Publisher: name: arXiv
Year: 2010
Subjects: subject: Methodology (stat.ME)
subject: FOS: Computer and information sciences

description: Familiar statistical tests and estimates are obtained by the direct observation of cases of interest: a clinical trial of a new drug, for instance, will compare the drug's effects on a relevant set of patients and controls. Sometimes, though, indirect evidence may be temptingly available, perhaps the results of previous trials on closely related drugs. Very roughly speaking, the difference between direct and indirect statistical evidence marks the boundary between frequentist and Bayesian thinking. Twentieth-century statistical practice focused heavily on direct evidence, on the grounds of superior objectivity. Now, however, new scientific devices such as microarrays routinely produce enormous data sets involving thousands of related situations, where indirect evidence seems too important to ignore. Empirical Bayes methodology offers an attractive direct/indirect compromise. There is already some evidence of a shift toward a less rigid standard of statistical objectivity that allows better use of indirect evidence. This article is basically the text of a recent talk featuring some examples from current practice, with a little bit of futuristic speculation.

description: We analyze the dynamics of individual kilometer-size planetesimals in circumstellar orbits of a tight binary system. We include both the gravitational perturbations of the secondary star and a non-linear gas drag stemming from an eccentric gas disk with a finite precession rate. We consider several precession rates and eccentricities for the gas, and compare the results with a static disk in circular orbit. The disk precession introduces three main differences with respect to the classical static case: (i) The equilibrium secular solutions generated by the gas drag are no longer fixed points in the averaged system, but limit cycles with frequency equal to the precession rate of the gas. The amplitude of the cycle is inversely dependent on the body size, reaching negligible values for $\sim 50$ km size planetesimals. (ii) The maximum final eccentricity attainable by small bodies is restricted to the interval between the gas eccentricity and the forced eccentricity, and apsidal alignment is no longer guaranteed for planetesimals strongly coupled with the gas. (iii) The characteristic timescales of orbital decay and secular evolution decrease significantly with increasing precession rates, with values up to two orders of magnitude smaller than for static disks. Finally, we apply this analysis to the $γ$-Cephei system and estimate impact velocities for different size bodies and values of the gas eccentricity. For high disk eccentricities, we find that the disk precession decreases the velocity dispersion between different size planetesimals, thus contributing to accretional collisions in the outer parts of the disk. The opposite occurs for almost circular gas disks, where precession generates an increase in the relative velocities.

Remembering and reuniting fragments : an autobiographical and theoretical exploration of children's stories offering healing and hope to a young child
Creators: name: Ehrenholz, Karen M
Publisher: name: University of British Columbia
Year: 2014

description: This thesis explores my relationship with my mother as a young child through the lens of children’s fiction and film. It is comprised of poems, each of which embodies my understanding of aspects of texts I engaged with throughout my early childhood. The poems are my response to themes, images, and phrases that I integrated into my own world view and belief systems in the context of a turbulent childhood. Themes that emerge include: a mother-daughter relationship, family secrets, trauma, abuse, and the transformative power of children’s book characters and stories. My exploration reveals the key role libraries and children’s fiction and film played in informing my childhood story. Children’s stories pulled me up and out of the ashes and rubble of my familial home and abusive maternal relationship. Children’s stories showered me with hope where none existed. This thesis is my attempt to distill the shadows and suffering of my childhood into something luminous and light (Martel, 2009). Visiting the library as well as reading and viewing children’s stories, helped me prosper emotionally, cognitively, and relationally; stories offered me healing. Through reading children’s books and projecting my thoughts and emotions onto the characters and their individual plights, I gathered insights, encouragement, clarity, and courage that helped me understand my mother in the broader context of my life, and to move beyond survival to thriving as a grown woman--as mother to my own children, as well as professional teacher nurturing the minds and hearts of others’ children. Following the poetic component of the thesis is a discussion of the approach I have undertaken, which might be described as a combination of poetic inquiry, narrative research, memoir, life writing, autobiography and autoethnography. I have elected to position this piece following the thesis, as a reflection, so as to let the poetry stand in the first place on its own, as a valid form of academic discourse.

description: This work employs Hall magnetohydrodynamic (MHD) simulations to study the X-lines formed during the reconnection of magnetic fields with differing strengths and orientations embedded in plasmas of differing densities. Although random initial perturbations trigger the growth of X-lines with many orientations, at late time a few robust X-lines sharing an orientation reasonably consistent with the direction that maximizes the outflow speed, as predicted by Swisdak and Drake [Geophys. Res. Lett., 34, L11106, (2007)], dominate the system. The existence of reconnection in the geometry examined here contradicts the suggestion of Sonnerup [J. Geophys. Res., 79, 1546 (1974)] that reconnection occurs in a plane normal to the equilibrium current. At late time the growth of the X-lines stagnates, leaving them shorter than the simulation domain.

subject: FOS: Physical sciences

description: This paper covers the main eddy current effects in accelerator magnets - field modification (time delay and field quality) and resistive power losses. In the first part, starting from the Maxwell equations, a basic understanding of the processes is given and explained with examples of simple geometry and time behaviour. Useful formulas are derived for an analytic estimate of the size of the effects. In the second part the effects in real magnets are analysed and described in comparison with numerical and measured results. Finally, based on the previous parts, design recommendations are given regarding how to minimize eddy current effects.

description: Common wisdom has it that small distinctions in the probabilities (parameters) quantifying a belief network do not matter much for the results of probabilistic queries. Yet, one can develop realistic scenarios under which small variations in network parameters can lead to significant changes in computed queries. A pending theoretical question is then to analytically characterize parameter changes that do or do not matter. In this paper, we study the sensitivity of probabilistic queries to changes in network parameters and prove some tight bounds on the impact that such parameters can have on queries. Our analytic results pinpoint some interesting situations under which parameter changes do or do not matter. These results are important for knowledge engineers as they help them identify influential network parameters. They also help explain some of the previous experimental results and observations with regards to network robustness against parameter changes.

The Scale Dependence of the Molecular Gas Depletion Time in M33

description: We study the Local Group spiral galaxy M33 to investigate how the observed scaling between the (kpc-averaged) surface density of molecular gas (Σ_H2) and recent star formation rate (Σ_SFR) relates to individual star-forming regions. To do this, we measure the ratio of CO emission to extinction-corrected Halpha emission in apertures of varying sizes centered both on peaks of CO and Halpha emission. We parameterize this ratio as a molecular gas (H_2) depletion time (τ_dep). On large (kpc) scales, our results are consistent with a molecular star formation law (Sigma_SFR \sim Sigma_H2^b) with b \sim 1.1 - 1.5 and a median τ_dep \sim 1 Gyr, with no dependence on type of region targeted. Below these scales, τ_dep is a strong function of adopted angular scale and the type of region that is targeted. Small (\lesssim 300pc) apertures centered on CO peaks have very long τ_dep (i.e., high CO-to-Halpha flux ratio) and small apertures targeted toward Halpha peaks have very short τ_dep. This implies that the star formation law observed on kpc scales breaks down once one reaches aperture sizes of \lesssim 300pc. For our smallest apertures (75pc), the difference in τ_dep between the two types of regions is more than one order of magnitude. This scale behavior emerges from averaging over star-forming regions with a wide range of CO-to-Halpha ratios with the natural consequence that the breakdown in the star formation law is a function of the surface density of the regions studied. We consider the evolution of individual regions the most likely driver for region-to-region differences in τ_dep (and thus the CO-to-Halpha ratio).

description: In this paper we have analyzed the temporal and spectral behavior of 52 Fast Rise and Exponential Decay (FRED) pulses in 48 long-duration gamma-ray bursts (GRBs) observed by the CGRO/BATSE, using a pulse model with two shape parameters and the Band model with three shape parameters, respectively. It is found that these FRED pulses are distinguished both temporally and spectrally from those in long-lag pulses. Different from these long-lag pulses only one parameter pair indicates an evident correlation among the five parameters, which suggests that at least $\sim$4 parameters are needed to model burst temporal and spectral behavior. In addition, our studies reveal that these FRED pulses have correlated properties: (i) long-duration pulses have harder spectra and are less luminous than short-duration pulses; (ii) the more asymmetric the pulses are the steeper the evolutionary curves of the peak energy ($E_{p}$) in the $νf_ν$ spectrum within pulse decay phase are. Our statistical results give some constrains on the current GRB models.

description: Since the external regions of the envelopes of rapidly rotating early-type stars are unstable to convection, a coupling may exist between the convection and the internal rotation. We explore what can be learned from spectroscopic and interferometric observations about the properties of the rotation law in the external layers of these objects. Using simple relations between the entropy and specific rotational quantities, some of which are found to be efficient at accounting for the solar differential rotation in the convective region, we derived analytical solutions that represent possible differential rotations in the envelope of early-type stars. A surface latitudinal differential rotation may not only be an external imprint of the inner rotation, but induces changes in the stellar geometry, the gravitational darkening, the aspect of spectral line profiles, and the emitted spectral energy distribution. By studying the equation of the surface of stars with non-conservative rotation laws, we conclude that objects undergo geometrical deformations that are a function of the latitudinal differential rotation able to be scrutinized both spectroscopically and by interferometry. The combination of Fourier analysis of spectral lines with model atmospheres provides independent estimates of the surface latitudinal differential rotation and the inclination angle. Models of stars at different evolutionary stages rotating with internal conservative rotation laws were calculated to show that the Roche approximation can be safely used to account for the gravitational potential. The surface temperature gradient in rapid rotators induce an acceleration to the surface angular velocity. A non-zero differential rotation parameter may indicate that the rotation is neither rigid nor shellular underneath the stellar surface.

Resource allocation in wireless systems with conventional and energy harvesting nodes
Creators: name: Ahmed, Imtiaz
Publisher: name: University of British Columbia
Year: 2014

description: High data rate, reliable communication, and low power consumption are the foremost demands for next generation of wireless communication systems. The key challenge to the design of communication systems is to combat the detrimental effects of channel fading, noise, and high power consumption. Wireless systems are often impaired by non-Gaussian noise, and the performance of systems designed for Gaussian noise can degrade if non-Gaussian noises are present but are not taken into account. Thus, it is imperative to analyze systems that are impaired by non-Gaussian noise and to manage their resources better to improve overall performance. Furthermore, there is significant interest in using renewable energy for wireless systems. However, energy harvesting (EH) is a random process and the harvested energy should be expended judiciously to maximize aggregate system throughput. In this thesis, we consider wireless systems that are impaired by Gaussian and non-Gaussian noise and powered by conventional energy sources and energy harvesters and propose appropriate resource allocation schemes for these systems. First, we propose optimal and fair power allocation schemes for a cooperative relay network with amplify-and-forward relays that employs best and partial relay selections and is impaired by Gaussian and non-Gaussian noise. We derive closed-form expressions of asymptotic bit error rate and use this expression to allocate transmit powers for different nodes with necessary energy consumption constraints. Second, we consider a network comprising a source, a relay, and a destination, where the source and the relay are EH nodes. We consider conventional and buffer-aided link adaptive relaying protocols, and propose offline and online resource allocation schemes that maximize the system throughput. Thirdly, we consider a multi-relay network with EH nodes and propose offline and online joint relay selection and power allocation schemes that maximize the system throughput. Fourth, we consider a single source-destination link, where the source has a hybrid energy supply comprised of constant energy source and energy harvester. We propose offline and online power allocation schemes that minimize the energy consumption from the constant energy source and thereby utilize the harvested energy effectively.
