description: This thesis examines option pricing for a Long Range Dependent (LRD) stochastic process with student marginal distributions called Fractal Activity Time Geometric Brownian Motion (FATGBM), introduced in Heyde (1999). We address four separate problems involving the pricing of options under FATGBM and other LRD stochastic processes. Following an introduction into the mechanics of derivative pricing, the thesis begins by addressing the problem of derivative pricing under FATGBM. We first develop the properties of FATGBM and show that the market is arbitrage-free but incomplete under this model. We then prove that there is no replicating strategy for this model except under special circumstances. We show that those special circumstances lead to the hedging of a Timer Option where interest rates are zero and we conclude by discussing the issue of completing the market by calibrating FATGBM to liquid risky assets such as European Options, as discussed in Carr et al. (2001). We then describe how to price path dependent options under FATGBM. We first propose a non-recombining tree that is used to then construct a recombining tree to price path dependent options. Further, we prove that our discrete time model converges to the continuous time one, resulting in a discrete approximation scheme for path dependent options. We then prove that the discrete approximation scheme results in an upper bound for the price of an American put. The next chapter addresses the problem of sampling from the distribution of FATGBM conditional on price history. Given that FATGBM is a LRD process, it is imperative to be able to simulate future price paths given a price path history. We propose a Markov Chain Monte Carlo (MCMC) approach to develop two algorithms for two different LRD processes, one FATGBM and one similar to FATGBM that we call FATGBM 2. We prove that the algorithms result in a Markov chain with a stationary distribution identical to the conditional distribution from which we wish to sample. We then discuss the implementation of both algorithms and compare the mixing times and features of the resultant conditional distribution. The final chapter combines the themes and results of the preceding chapters by using the MCMC algorithm in conjunction with the recombining tree developed in Chapter 2. The result is an analysis of the effect of long range dependence on option prices, the most compelling finding being that LRD has more of an impact on the option price than the impact of heavy tails alone, a phenomenon that has thus far been overlooked by the literature on option pricing. We conclude with an analysis of the implied volatility surface arising from FATGBM and discuss the implications of our research in the context of the existing literature.

description: We investigate the bubble nucleation in five dimensional spacetime catalyzed by quintessence. We especially focus on decay of a metastable Minkowski vacuum to an anti-de Sitter vacuum and study dynamics of the bubble on which four dimensional expanding universe is realized. We also discuss the trans-Planckian censorship conjecture and impose a constraint on the parameter space of the catalysis. As an application of this model, we propose an inflation mechanism and an origin of the dark energy in the context of quintessence in five dimensions.

description: We formulate and study a quantum field theory of a microtubule, a basic element of living cells. Following the quantum theory of consciousness by Hameroff and Penrose, we let the system to reduce to one of the classical states without measurement if certain conditions are satisfied(self-reductions), and calculate the self-reduction time $τ_N$ (the mean interval between two successive self-reductions) of a cluster consisting of more than $N$ neighboring tubulins (basic units composing a microtubule). $τ_N$ is interpreted there as an instance of the stream of consciousness. We analyze the dependence of $τ_N$ upon $N$ and the initial conditions, etc. For relatively large electron hopping amplitude, $τ_N$ obeys a power law $τ_N \sim N^b$, which can be explained by the percolation theory. For sufficiently small values of the electron hopping amplitude, $τ_N$ obeys an exponential law, $τ_N \sim \exp(c' N)$. By using this law, we estimate the condition for $τ_N $ to take realistic values $τ_N$ \raisebox{-0.5ex}{$\stackrel{>}{\sim}$} $10^{-1}$ sec as $N$ \raisebox{-0.5ex} {$\stackrel{>}{\sim}$} 1000.

description: Thermodynamics of the Kitaev honeycomb magnet $α$-RuCl$_3$ is studied for different directions of in-plane magnetic field using measurements of the magnetic Grüneisen parameter $Γ_B$ and specific heat $C$. We identify two critical fields $B_c^{\rm AF1}$ and $B_c^{\rm AF2}$ corresponding, respectively, to a transition between two magnetically ordered states and the loss of magnetic order toward a quantum paramagnetic state. The $B_c^{AF2}$ phase boundary reveals a narrow region of magnetic fields where inverse melting of the ordered phase may occur. No additional transitions are detected above $B_c^{\rm AF2}$ for any direction of the in-plane field, although a shoulder anomaly in $Γ_B$ is observed systematically at $8-10$ T. Large field-induced entropy effects imply additional low-energy excitations at low fields and/or strongly field-dependent phonon entropies. Our results establish universal features of $α$-RuCl$_3$ in high magnetic fields and challenge the presence of a field-induced Kitaev spin liquid in this material.

description: We report on the detection of hot CO2 in the O-rich AGB star R Leo based on high spectral resolution observations in the range 12.8-14.3 µm carried out with the Echelon-cross-Echelle Spectrograph (EXES) mounted on the Stratospheric Observatory for Infrared Astronomy (SOFIA). We have found ~240 CO2 emission lines in several vibrational bands. These detections were possible thanks to a favorable Doppler shift that allowed us to avoid contamination by telluric CO2 features. The highest excitation lines involve levels at an energy of ~7000 K. The detected lines are narrow (average deconvolved width ~2.5 km s-1) and weak (usually <10% the continuum). A ro-vibrational diagram shows that there are three different populations, warm, hot, and very hot, with rotational temperatures of ~550, 1150, and 1600 K, respectively. From this diagram, we derive a lower limit for the column density of ~2.2×1016 cm-2. Further calculations based on a model of the R Leo envelope suggest that the total column density can be as large as 7×1017 cm-2 and the abundance with respect to H2 ~2.5×10-5. The detected lines are probably formed due to de-excitation of CO2 molecules from high energy vibrational states, which are essentially populated by the strong R Leo continuum at 2.7 and 4.2 µm.
Radio Spectrum and Distance of the SNR HB9

description: New images are presented of the supernova remnant (SNR) HB9 based on 408 MHz and 1420 MHz continuum emission and HI-line emission data of the Canadian Galactic Plane Survey (CGPS) by the Dominion Radio Astrophysical Observatory (DRAO). Two methods of spectral index analysis for HB9 are presented and compared: one removes compact sources at both frequencies but is limited to the resolution of the 408 MHz image; the other removes compact sources only in the 1420 MHz image so is effective at higher spatial resolution. The second allows more detailed spectral index variation studies than the first. The two T-T plot methods and new integrated flux densities give spectral index (S_ν\proptoν^{-alpha}) for the whole of HB9 of 0.48+-0.03; and 0.47+-0.06, respectively. These are lower than previous spectral index for HB9 (alpha=0.61). Spatial variations of spectral index are derived using the second method and yield a steeper spectral index for interior regions than for the rim. This can be explained by a standard curved interstellar electron energy spectrum combined with lower interior magnetic field compared to that near the outer shock, which results in a larger proportion of steep spectrum emission for lines-of-sight through the central body of the SNR. HI observations show structures probably associated with the SNR in the radial velocity range -3 to -9 km/s and suggest a distance of 0.8+-0.4 kpc for the SNR. This is consistent with the distance to the radio pulsar 0458+46, offset from the center of HB9 by 23'. However the pulsar spindown and kinematic ages are significantly greater than estimates of the SNR age: the Sedov age for HB9 is 6600 yr and the evaporative cloud model yields ages of 4000-7,000 yr.

Using the Starlight Polarization Efficiency Integral to Constrain Shapes and Porosities of Interstellar Grains

Subjects: subject: Astrophysics of Galaxies (astro-ph.GA)

description: We present a new method for using the observed starlight polarization and polarized submm emission to constrain the shapes and porosities of interstellar grains. We present the modified picket fence approximation (MPFA), and verify that it is sufficiently accurate for modeling starlight polarization. We introduce the starlight polarization integral $Π_{\rm obs}$ as a measure of overall strength of the observed polarization of starlight, and the starlight polarization efficiency integral $Φ$ to characterize the effectiveness of different grain types for producing polarization of starlight. The starlight polarization integral $Π_{\rm obs}$ determines the mass-weighted alignment $\langle f_{\rm align}\rangle$ of the grains. Approximating the aligned grains in the interstellar medium as spheroids, we use $Π_{\rm obs}/Φ$ to show that the observed starlight polarization constrains the grains to have a minimum degree of asphericity. For porosity ${\cal P}=0$, the minimum axial ratio is $\sim$1.4 for oblate spheroids, or $\sim$1.8 for prolate spheroids. If the grains are porous, more extreme axial ratios are required. The same grains that produce the starlight polarization are able to provide the observed polarized emission at submm wavelengths, but with further limits on shape and porosity. Porosities ${\cal P}>0.75$ are ruled out. If interstellar grains can be approximated by astrodust spheroids, we predict the ratio of 10$μ{\rm m}$ polarization to starlight polarization $p_V$: $p(10μ{\rm m})/p_V=0.222\pm0.026$. For Cyg OB2-12 we predict $p(10μ{\rm m})=(2.1\pm0.3)\%$, which should be observable.

Properties of thus obtained graphene quantum dots are investigated theoretically for different types of the boundary conditions at the edges of the strip. The (quasi)bound states exist in all systems considered. At the same time, the dependence of the conductance on the gate voltage carries an information about the shape of the edges.

description: A scheme for dynamical stabilization of entanglement quantified by the quantum Fisher information is analyzed numerically and analytically for bimodal and spin-1 Bose-Einstein condensates in the context of atomic interferometry. The scheme consists of twisting dynamics followed by a single rotation of a state which limits further evolution around stable center fixed points in the mean-field phase space. The resulting level of entanglement is of the order or larger than at the moment of rotation. It is demonstrated that the readout measurement of parity quantifies the level of entanglement during entire evolution.

description: We investigate quantum dynamics of a quantum walker on a finite bipartite non-Hermitian lattice, in which the particle can leak out with certain rate whenever it visits one of the two sublattices. Quantum walker initially located on one of the non-leaky sites will finally totally disappear after a length of evolution time and the distribution of decay probability on each unit cell is obtained. In one regime, the resultant distribution shows an expected decreasing behavior as the distance from the initial site increases. However, in the other regime, we find that the resultant distribution of local decay probability is very counterintuitive, in which a relatively high population of decay probability appears on the edge unit cell which is the farthest from the starting point of the quantum walker. We then analyze the energy spectrum of the non-Hermitian lattice with pure loss, and find that the intriguing behavior of the resultant decay probability distribution is intimately related to the existence and specific property of edge states, which are topologically protected and can be well predicted by the non-Bloch winding number. The exotic dynamics may be observed experimentally with arrays of coupled resonator optical waveguides.

UPD-Glucose : sinapic acid glucosyltransferase in Brassicaceae
Creators: name: Wang, Shawn X.
Publisher: name: University of British Columbia
Year: 2009

description: Sinapine is a bitter phenolic choline ester that is ubiquitous in crucifer seeds. It occupies about 1-4% of the dry matter of rapeseed. Elimination of sinapine from the seeds would improve the flavor, palatability and nutritional properties of rapeseed meal for its utilization as supplemental protein source for animal feed. UDP-glucose:sinapic acid glucosyltransferase (SGT; EC 2.4.1.120) is a key enzyme involved in biosynthesis of both sinapine in seed and sinapoylmalate in vegetative tissues of many members of Brassicaceae. Both esters are strongly UV-absorbing but their physiological functions in plants are unknown. By a series of column chromatography techniques, SGT has been purified from 60-h-old seedlings of Brassica napus and characterized. SGT is a monomeric polypeptide with a molecular weight of 42 kDa and a pi of pH 5. The subcellular location of SGT appears to be the cytosol. SGT activity is not inducible by heat shock or UV radiation stresses. Its general characteristics are similar to those of SGT from Raphanus sativus, as well as a number of other UDP-glucose-dependent glucosyltransferases. The K[sub m (UDP-glucose)] was 0.24 mM and K[sub m (sinapic acid)] was 0.16 mM. SGT also catalyzes the reverse reaction in vitro, using UDP and sinapoylglucose to form UDP-glucose. No cofactors are required for SGT activity, but reducing reagents and glycerol are required to stabilize the enzyme. The enzyme is strongly inhibited by phydroxyl-mercuribenzoic acid, UDP, TDP, Zn⁺⁺, Cu⁺⁺ and Hg⁺⁺. Kinetic properties and substrate affinity data suggest that the catalytic mechanism of SGT is best described by a "random bi-bi" model. An analysis of developmental profiles showed that SGT was expressed in all growth stages of B. napus plants, but was most active during the early germination and seed development stages, particularly in cotyledons, juvenile leaves and young shoots. Partial amino acid sequence data were obtained from tryptic digests of the putative SGT protein. These sequences showed a very high degree of similarity to the HSP/HSC70 protein family.
Gravitational wave in f(R) gravity: possible signature of sub- and super-Chandrasekhar limiting mass white dwarfs

description: After the prediction of many sub- and super-Chandrasekhar (at least a dozen for the latter) limiting mass white dwarfs, hence apparently peculiar class of white dwarfs, from the observations of luminosity of type Ia supernovae, researchers have proposed various models to explain these two classes of white dwarfs separately. We earlier showed that these two peculiar classes of white dwarfs, along with the regular white dwarfs, can be explained by a single form of the f(R) gravity, whose effect is significant only in the high-density regime, and it almost vanishes in the low-density regime. However, since there is no direct detection of such white dwarfs, it is difficult to single out one specific theory from the zoo of modified theories of gravity. We discuss the possibility of direct detection of such white dwarfs in gravitational wave astronomy. It is well-known that in f(R) gravity, more than two polarization modes are present. We estimate the amplitudes of all the relevant modes for the peculiar as well as the regular white dwarfs. We further discuss the possibility of their detections through future-based gravitational wave detectors, such as LISA, ALIA, DECIGO, BBO, or Einstein Telescope, and thereby put constraints or rule out various modified theories of gravity. This exploration links the theory with possible observations through gravitational wave in f(R) gravity.

description: We investigate the local correlation betwen the 1.4 GHz radio continuum and 60 micron far-infrared (FIR) emission within the Large Magellanic Cloud (LMC) on spatial scales between 0.05 and 1.5 kpc. On scales below ~1 kpc, the radio-FIR correlation is clearly better than the correlation of the cold gas tracers with either the radio or the FIR emission. For the LMC as a whole, there is a tight correlation between the radio and FIR emission on spatial scales above ~50 pc. By decomposing the radio emission into thermal and non-thermal components, however, we show that the scale on which the radio-FIR correlation breaks down is inversely proportional to the thermal fraction of the radio emission: regions that show a strong correlation to very small scales are the same regions where the thermal fraction of the radio emission is high. Contrary to previous studies of the local radio-FIR correlation in the LMC, we show that the slope of the relation between the radio and FIR emission is non-linear. In bright star-forming regions, the radio emission increases faster than linearly with respect to the FIR emission (power-law slope of ~1.2), whereas a flatter slope of ~0.6-0.9 applies more generally across the LMC. Our results are consistent with a scenario in which the UV photons and cosmic rays in the LMC have a common origin in massive star formation, but the cosmic rays are able to diffuse away from their production sites. Our results do not provide direct evidence for coupling between the magnetic field and the local gas density, but we note that synchrotron emission may not be a good tracer of the magnetic field if cosmic rays can readily escape the LMC.

However, we show that there is a class of W-states that can be used for perfect teleportation and superdense coding.

description: Cancer is a complex disease whose global burden has made it absolute necessity for its early detection. In this regard, the short non-coding RNA molecules- microRNAs (miRNAs) have shown great promise due to their availability in circulating fluids facilitating non-invasive detection of cancer. In this study, an in silico comparative analysis was performed to identify specific signature miRNAs dys-regulated across multiple carcinomas. The miRNA-seq data of cancer patient was obtained from GDC portal and their differential expressions along with the pathways regulated were analyzed. Our studies show twelve miRNAs commonly dys-regulated across seven different cancer types. Interestingly, four of those miRNAs (hsa-mir-210, hsa-mir-19a, hsa-mir-7 and hsa-mir-3662) are already reported as circulatory miRNAs (circRNAs); while, the miR-183 cluster along with hsa-mir-93 have been found to be incorporated in exosomes signifying the importance of the identified miRNAs for their use as prospective, non-invasive bio-markers. Furthermore, we identified 6 common miRNAs which are being reported for the first time as cancer biomarkers. Our data is of significance because we not only identify a set of common miRNAs de-regulated in multiple cancers but also highlight similar pathways regulated by them, which might facilitate development of future non-invasive biomarkers conducive for early detection of cancers

description: Two-dimensional triangular-lattice antiferromagnets are predicted under some conditions to exhibit a quantum spin liquid ground state whose low-energy behavior is described by a spinon Fermi surface. Directly imaging the resulting spinons, however, is difficult due to their fractional, chargeless nature. Here we use scanning tunneling spectroscopy to image spinon density modulations arising from a spinon Fermi surface instability in single-layer 1T-TaSe$_2$, a two-dimensional Mott insulator. We first demonstrate the existence of localized spins arranged on a triangular lattice in single-layer 1T-TaSe$_2$ by contacting it to a metallic 1H-TaSe$_2$ layer and measuring the Kondo effect. Subsequent spectroscopic imaging of isolated, single-layer 1T-TaSe$_2$ reveals long-wavelength modulations at Hubbard band energies that reflect spinon density modulations. This allows direct experimental measurement of the spinon Fermi wavevector, in good agreement with theoretical predictions for a 2D quantum spin liquid. These results establish single-layer 1T-TaSe$_2$ as a new platform for studying novel two-dimensional quantum-spin-liquid phenomena.

description: We present a novel open-source Python framework called NanoNET (Nanoscale Non-equilibrium Electron Transport) for modelling electronic structure and transport. Our method is based on the tight-binding method and non-equilibrium Green's function theory. The core functionality of the framework is providing facilities for efficient construction of tight-binding Hamiltonian matrices from a list of atomic coordinates and a lookup table of the two-center integrals in dense, sparse, or block-tridiagonal forms. The framework implements a method based on $kd$-tree nearest-neighbour search and is applicable to isolated atomic clusters and periodic structures. A set of subroutines for detecting the block-tridiagonal structure of a Hamiltonian matrix and splitting it into series of diagonal and off-diagonal blocks is based on a new greedy algorithm with recursion. Additionally the developed software is equipped with a set of programs for computing complex band structure, self-energies of elastic scattering processes, and Green's functions. Examples of usage and capabilities of the computational framework are illustrated by computing the band structure and transport properties of a silicon nanowire as well as the band structure of bulk bismuth.

description: Two-dimensional (2D) transition metal dichalcogenides (TMDCs) are the subject of intense investigation for applications in optics, electronics, catalysis, and energy storage. Their optical and electronic properties can be significantly enhanced when encapsulated in an environment that is free of charge disorder. Because hexagonal boron nitride (h-BN) is atomically thin, highly-crystalline, and is a strong insulator, it is one of the most commonly used 2D materials to encapsulate and passivate TMDCs. In this report, we examine how ultrathin h-BN shields an underlying MoS2 TMDC layer from the energetic argon plasmas that are routinely used during semiconductor device fabrication and post-processing. Aberration-corrected Scanning Transmission Electron Microscopy is used to analyze defect formation in both the h-BN and MoS2 layers, and these observations are correlated with Raman and photoluminescence spectroscopy. Our results highlight that h-BN is an effective barrier for short plasma exposures (< 30 secs) but is ineffective for longer exposures, which result in extensive knock-on damage and amorphization in the underlying MoS2.

description: The spectra of active galactic nuclei usually exhibit wings in some emission lines, such as [OIII]$λλ$5007,4959, with these wings generally being blueshifted and related to strong winds and outflows. The aim of this work was to analyse the [OIII] emission lines in broad line Seyfert 1 (BLS1) galaxies in order to detect the presence of wings, and to study the [OIII] line properties and their possible connection with the central engine. In addition, we attempted to compare the black hole mass distribution in both BLS1 galaxies with symmetric and blue-asymmetric [OIII] profiles. For this purpose, we carried out a spectroscopic study of a sample of 45 nearby southern BLS1 galaxies from the 6 Degree Field Galaxy survey. The [OIII] emission lines were well fitted using a single Gaussian function in 23 galaxies, while 22 objects presented a wing component and required a double-Gaussian decomposition. By computing the radial velocity difference between the wing and core centroids (i.e. $Δ$v), we found 18 galaxies exhibiting blueshifted wings, 2 objects presenting red wings and 2 galaxies showing symmetric wings ($Δ$v$= 0$). Moreover, $Δ$v was slightly correlated with the black hole mass. In addition, we computed the radial velocity difference of the blue-side full extension of the wing relative to the centroid of the core component through the \emph{blue emission} parameter, which revealed a correlation with black hole mass, in agreement with previous results reported for narrow line galaxies. Finally, in our sample, similar black hole mass distributions were observed in both BLS1 galaxies with symmetric and blueshifted asymmetric [OIII] profiles.

description: We present extensive new photometry in (g',i') of the large globular cluster (GC) system around NGC 3311, the central cD galaxy in the Hydra cluster. Our GMOS data cover a 5.5' field of view and reach a limiting magnitude i' = 26, about 0.5 magnitude fainter than the turnover point of the GC luminosity function. We find that NGC 3311 has a huge population of ~16, 000 GCs, closely similar to the prototypical high specific frequency Virgo giant M87. The color-magnitude distribution shows that the metal-poor blue GC sequence and the metal-richer red sequence are both present, with nearly equal numbers of clusters. Bimodal fits to the color distributions confirm that the blue sequence shows the same trend of progressively increasing metallicity with GC mass that has previously been found in many other large galaxies; the correlation we find corresponds to a scaling of GC metallicity with mass of Z ~ M^0.6 . By contrast, the red sequence shows no change of mean metallicity with mass, but it shows an upward extension to much higher than normal luminosity into the UCD-like range, strengthening the potential connections between massive GCs and UCDs. The GC luminosity function, which we measure down to the turnover point at M_I = -8.4, also has a normal form like those in other giant ellipticals. Within the Hydra field, another giant elliptical NGC 3309 is sitting just 100" from the cD NGC 3311. We use our data to solve simultaneously for the spatial structure and total GC populations of both galaxies at once. Their specific frequencies are S_N (NGC 3311) = 12.5 +/- 1.5 and S_N (NGC 3309) = 0.6 +/-0.4. NGC 3311 is completely dominant and entirely comparable with other cD-type systems such as M87 in Virgo.

description: This paper presents a novel knowledge distillation based model compression framework consisting of a student ensemble. It enables distillation of simultaneously learnt ensemble knowledge onto each of the compressed student models. Each model learns unique representations from the data distribution due to its distinct architecture. This helps the ensemble generalize better by combining every model's knowledge. The distilled students and ensemble teacher are trained simultaneously without requiring any pretrained weights. Moreover, our proposed method can deliver multi-compressed students with single training, which is efficient and flexible for different scenarios. We provide comprehensive experiments using state-of-the-art classification models to validate our framework's effectiveness. Notably, using our framework a 97% compressed ResNet110 student model managed to produce a 10.64% relative accuracy gain over its individual baseline training on CIFAR100 dataset. Similarly a 95% compressed DenseNet-BC(k=12) model managed a 8.17% relative accuracy gain.
