description: This study aims to develop of a novel in vitro model for pain research, focusing on the TRPV1 receptor, which plays a crucial role in pain mechanisms. Given the limitations of current therapies in treating pain sensation without targeting underlying causes, this research aims to advance understanding of TRPV1’s role in neuronal hyperexcitability and its potential as a therapeutic target. The ND7/23 cell line was transfected with human TRPV1 to create a stable neuronal model that closely mimics dorsal root ganglion neurons, known for their role in pain transmission. This model allows for a detailed investigation of TRPV1’s functionality, particularly its interactions with voltage-gated ion channels, which are key in modulating neuronal excitability and pain signalling. Capsaicin, a natural compound known for activating TRPV1, was used to evaluate the model’s effectiveness. Calcium imaging confirmed capsaicin responsiveness to TRPV1 in ND7/23-TRPV1 cells. Automated patch clamp experiments demonstrated full functionality of TRPV1 in response to heat and pH, as well as the specificity TRPV1-capsaicin binding, with the use of capsazepine. In dose response studies capsaicin demonstrated a higher potency in ND7/23-TRPV1 cells compared to CHO-TRPV1 cells, confirming its neuronal characteristics. In further studies, capsaicin highlighted its potential in modulating ionic currents and action potentials. The findings suggest that capsaicin, through TRPV1 activation, can modulate neuronal activity, offering promise as a therapeutic agent for chronic pain management. This study establishes a robust in vitro model for pain research, offering new insights into the complex mechanisms of pain. It underscores the critical role of TRPV1 in modulating neuronal excitability, laying the foundation for the development of targeted analgesic therapies.
Hearing meter from different angles : interactive vocal meter and hypermeter in selected songs and their covers
Creators: name: Hardman, Kristi Dawn
Publisher: name: University of British Columbia
Year: 2016

description: A vocal melody is a setting of poetry to musical rhythms and pitches. The poetry and the musical melody have distinct accentuation patterns, yet as musicians we too often only analyse the musical events of a vocal melody in order to determine its rhythmic structure and meter, while ignoring the meter of the poetic text. This thesis examines how the meter of the poetic text interacts with the meter of the musical melody to inform our overall perception of the vocal melody’s meter. Through comparison of popular songs with cover versions that adopt a different meter, it investigates how the same poetic meter interacts with different musical meters, and studies the resulting effects on vocal meter and hypermeter. The methodology can be applied to a wide range of popular music genres, so each chapter examines an original song and cover versions representing different genres. The first chapter establishes the new methodology developed in this thesis. The concepts of poetic meter, melodic meter, and the resulting “interactive vocal meter” are introduced and applied in the analysis of three versions of Hank Williams’s “I’m So Lonesome I Could Cry.” This chapter also explores some novel ways in which we can interpret syncopations and hypermeter. Interactive vocal meter is further explored in chapter 2 through the analysis of two versions of the Beatles’ “I’ll Be Back.” The change in meter, from the 6/8 of the demo to the 4/4 of the single, offers a fascinating opportunity to study the rhetorical and musical impact of subtle changes in accentuation. The complex phrase structure of “I’ll Be Back” also introduces interesting issues and questions regarding our perception of hypermeter. The third chapter focuses on Billie Holiday’s “Strange Fruit.” Holiday’s transformations of the poem’s unusual metric contours provide a vivid demonstration of her uniquely eloquent idiom. The vocal metric interpretation of “Strange Fruit” challenges the view that beats 1 and 3 are always strongly accentuated beats in 4/4 measures. This chapter also explores issues of rhythmic and metric transcription in connection with Lori Burn’s recent study of Tori Amos’s cover of the song.

description: The theory of dynamic conductivity of nanosystem is developed within the model of rectangular potentials and different effective masses of electron in open three-barrier resonance-tunnel structure in a constant homogeneous electric field. The application of this theory for the improvement of operating characteristics of quantum cascade laser active region (for the experimentally investigated In$_{0.53}$Ga$_{0.47}$As/In$_{0.52}$Al$_{0.48}$As heterosystem) proves that for a certain geometric design of nanosystem there exists such minimal magnitude of constant electric field intensity, at which the electromagnetic field radiation power together with the density of current flowing through the separate cascade of quantum laser becomes maximal.

description: Spherical magnetite nanoparticles having average particle size = 5 nm have been synthesized by coprecipitation of Fe(II) and Fe(III) salts in KOH with Polyvinylalcohol (PVA). The resulting dry powder displayed superparamgnetic (SPM) behaviour at room temperature, with a transition to a blocked state at TB ~ 45 K for applied field Happ = 500 Oe. The effect of dipolar interactions was investigated by measuring the dependence of TB on the applied field Hap and driven ac field in susceptibility data. A thermally activated model has been used to fit the dynamic data to obtain the single-particle energy barriers Ea = KeffV, allowing us to estimate the contributions of dipolar interactions to the single-particle effective magnetic anisotropy Keff. We have measured the dependence of TB with Hap in order to draw the transition contours of a H-T diagram. Two different regimes are found for the (TB-T0) ~Hλ dependence at low and high fields, that can be understood within a pure SPM relaxation-time (Néel-Brown) landscape. The TB(H) data shows a crossover from λ = 2/3 to λ ~2 for applied magnetic fields of \approx 550 Oe.

description: The intrinsic stochasticity of gene expression can lead to large variability of protein levels across a population of cells. Variability (or noise) in protein distributions can be modulated by cellular mechanisms of gene regulation; in particular, there is considerable interest in understanding the role of post-transcriptional regulation. To address this issue, we propose and analyze a stochastic model for post-transcriptional regulation of gene expression. The analytical solution of the model provides insight into the effects of different mechanisms of post-transcriptional regulation on the noise in protein distributions. The results obtained also demonstrate how different sources of intrinsic noise in gene expression can be discriminated based on observations of regulated protein distributions.

description: We study four Achlioptas type processes with "explosive" percolation transitions. All transitions are clearly continuous, but their finite size scaling functions are not entire holomorphic. The distributions of the order parameter, the relative size $s_{\rm max}/N$ of the largest cluster, are double-humped. But -- in contrast to first order phase transitions -- the distance between the two peaks decreases with system size $N$ as $N^{-η}$ with $η> 0$. We find different positive values of $β$ (defined via $< s_{\rm max}/N > \sim (p-p_c)^β$ for infinite systems) for each model, showing that they are all in different universality classes. In contrast, the exponent $Θ$ (defined such that observables are homogeneous functions of $(p-p_c)N^Θ$) is close to -- or even equal to -- 1/2 for all models.

It has a mass of $2.43\pm0.30$\Mjup and a radius of $1.02\pm0.07$\Rjup, while its mean density is $2.82\pm0.38$ g/cm$^3$. CoRoT-17b is in a circular orbit with a period of $3.7681\pm0.0003$ days. The host star is an old ($10.7\pm1.0$ Gyr) main-sequence star, which makes it an intriguing object for planetary evolution studies. The planet's internal composition is not well constrained and can range from pure H/He to one that can contain $\sim$380 earth masses of heavier elements.

description: Aims: We investigated the X-ray emission from young stars and brown dwarfs in the sigma Orionis cluster (tau~3 Ma, d~385 pc) and its relation to mass, presence of circumstellar discs, and separation to the cluster centre by taking advantage of the superb spatial resolution of the Chandra X-ray Observatory. Methods: We used public HRC-I/Chandra data from a 97.6 ks pointing towards the cluster centre and complemented them with X-ray data from IPC/Einstein, HRI/ROSAT, EPIC/XMM-Newton, and ACIS-S/Chandra together with optical and infrared photometry and spectroscopy from the literature and public catalogues. On our HRC-I/Chandra data, we measured count rates, estimated X-ray fluxes, and searched for short-term variability. We also looked for long-term variability by comparing with previous X-ray observations. Results: Among the 107 detected X-ray sources, there were 70 cluster stars with known signposts of youth, two young brown dwarfs, 12 cluster member candidates, four field dwarfs, and two galaxies with optical-infrared counterpart. The remaining sources had extragalactic nature. Based on a robust Poisson-chi^2 analysis, nine cluster stars displayed flares or rotational modulation during the HRC-I observations, while other eight stars and one brown dwarf showed long-term X-ray flux variations. We constructed a cluster X-ray luminosity function from O9.5 (~18 Msol) to M6.5 (~0.06 Msol). We found: a tendency of early-type stars in multiple systems or with spectroscopic peculiarities to display X-ray emission, that the two detected brown dwarfs and the least-massive star are among the sigma Orionis objects with the highest L_X/L_J ratios, and that a large fraction of known classical T Tauri stars in the cluster are absent in this and other X-ray surveys. We concluded that dozens X-ray sigma Orionis stars and brown dwarfs are still to be detected [abridged].

description: We study the entanglement entropy in a relativistic quantum field theory for regions which are not included in a single spatial hyperplane. This geometric configuration cannot be treated with the Euclidean time method and the replica trick. Instead, we use a real time method to calculate the entropy for a massive free Dirac field in two dimensions in some approximations. We find some specifically relativistic features of the entropy. First, there is a large enhancement of entanglement due to boosts. As a result, the mutual information between relatively boosted regions does not vanish in the limit of zero volume and large relative boost. We also find extensivity of the information in a deeply Lorentzian regime with large violations of the triangle inequalities for the distances. This last effect is relevant to an interpretation of the amount of entropy enclosed in the Hawking radiation emitted by a black hole.

The genetic basis of transformation and progression in follicular lymphoma
Creators: name: Kridel, Robert
Publisher: name: University of British Columbia
Year: 2016

description: The clonal evolution theory of cancer has been recognized for decades and follows principles of Darwinian selection, in which there is selection of the fittest clones in an ecosystem that is fundamentally heterogeneous and undergoes selective pressure. Follicular lymphoma (FL) emerges as a prototypical disease in which to study clonal evolution. It is the most common indolent lymphoma and, although the median overall survival largely surpasses 10 years, patients almost invariably experience progressive disease. Furthermore, a subset of FL patients is at risk of early lymphoma-related death due to rapid progression or transformation to aggressive lymphoma. Yet, the clonal dynamics and the landscape of genomic alterations underlying progression and transformation remain to be uncovered. Herein, we applied whole genome sequencing to a discovery set of transformed, progressed and non-progressed FL cases, re-constructed clonal phylogenies, and interrogated a larger set of transformed FLs and clinical extremes by capture-based targeted sequencing. Moreover, we applied the Lymph2Cx cell-of-origin assay to determine whether molecular subtypes can be defined in transformed follicular lymphoma (TFL) by gene-expression profiling. We discovered that transformation is typically the result of drastic clonal shifts during which TFL-specific clones rapidly outcompete indolent clones. In a subset of cases, these aggressive clones can be found at low levels (< 1% of tumour cells) at diagnosis. In contrast, primary progression generally results from the outgrowth of subclones that are readily detectable at diagnosis, suggesting that the genomic features conferring treatment resistance can be detected prior to initial treatment using low-pass sequencing technology. In addition, we identified discrete gene mutations that are associated with early progression and transformation, and uncovered that a subset of TFLs (16%) have an activated B-cell phenotype and are enriched for mutations in CD79B and BCL10. In summary, we found striking contrast in clonal trajectories between distinct clinical scenarios and described novel associations of gene mutations with transformation and progression. Our findings have translational relevance as they suggest that early progression, and to a lesser extent transformation, can potentially be predicted at diagnosis and thus provide a rationale for novel therapeutic approaches in TFL.

description: Knowledge of Neogene fish diversity in Taiwan is extremely limited. In this paper, we present a collection of 1716 fish otoliths recovered from the late Miocene Tapu Formation. The abundance and density of otoliths vary across the sites. Although the preservation of samples is considerably limited, our sample coverage is sufficient and reveals the presence of at least 34 otolith-based taxa belonging to 13 families. Four new species are introduced: Larimichthys koae sp. nov., Nibea chaoi sp. nov., Taosciaena jiangi sp. nov., and T. hui sp. nov. Among the earliest fossil records, this collection features a remarkable abundance of Larimichthys spp. The assemblage is dominated by otoliths of Sciaenidae, Gobiidae and Soleidae, and it is indicative of a coastal shallow-water palaeoenvironment with muddy to sandy bottoms, perhaps adjacent to a river mouth. We hypothesise that the differences in the taxonomic composition between the fossil assemblage and modern fauna are mainly chronological and evolutionary, and only a moderate turnover of certain lineages has occurred since the Miocene. Our study provides a unique ‘window’ to a rarely visited fossil fish community that exclusively documented by fossil otolith data, and reveals a past coastal fish diversity that otherwise could not be recognised.

description: We evaluate the Wald Noether charge entropy for a black hole in generalized theories of gravity. Expanding the Lagrangian to second order in gravitational perturbations, we show that contributions to the entropy density originate only from the coefficients of two-derivative terms. The same considerations are extended to include matter fields and to show that arbitrary powers of matter fields and their symmetrized covariant derivatives cannot contribute to the entropy density. We also explain how to use the linearized gravitational field equation rather than quadratic actions to obtain the same results. Several explicit examples are presented that allow us to clarify subtle points in the derivation and application of our method.
Echo of the master, shadow of the Buddha : the Liezi as a medieval masters text
Creators: name: Kreger, Wayne
Publisher: name: University of British Columbia
Year: 2016

description: The present work examines the Chinese Masters Text the Liezi, purported to be composed in the 5th century BCE, though more likely achieving its current form in the 4th century CE. It situates the claims Liezi in the intellectual and spiritual climate of 4th century CE in its role as a member of the Masters Text category, and reads the text's ontological and normative program in light of the flourishing xuanxue and prajñāpāramitā discourse of that era. Chapter One traces the evolution of the Masters Text category from the Warring States period, through the Han dynasty, and into the early medieval period, relying on the understanding of “Masters Text” offered by Wiebke Denecke in her Dynamics of Masters Literature (2010). I argue that textual authority accrued by this category serves as a sufficient impetus to create such an inauthentic document in approximately 350 CE. Chapter Two reviews the most recent contributions to the debate over the authenticity of the Liezi, and concludes that the text is certainly a 4th century CE compilation, though containing some earlier material. Chapter Three is a concise survey of the ontological and normative position of the text, with a chapter by chapter analysis of the Liezi. Chapter Four uses this analysis of the Liezi to compare the thought therein with contemporary thinkers such as Wang Bi, Guo Xiang, Ruan Ji, and Xi Kang. I conclude that the Liezi was likely compiled in an effort to argue for the ontological scheme of Wang Bi against that of Guo Xiang, and that it does not explicitly follow Ruan Ji or Xi Kang in advocating for the pursuit or practice of longevity techniques. Chapter Five compares notions of “Nonbeing” and “emptiness” in the Liezi to Buddhist speculations on “emptiness” unfolding in China up to and during the 4th century CE. I conclude that despite frequent speculation on the part of modern and pre-modern commentators, there is little conceptual alignment between the Liezi and the developing Buddhist schools.

description: Aims: We investigated in detail the system WDS 19312+3607, whose primary is an active M4.5Ve star previously thought to be young (tau ~ 300-500 Ma) based on high X-ray luminosity. Methods: We collected intermediate- and low-resolution optical spectra taken with 2 m-class telescopes, photometric data from the $B$ to 8 mum bands, and eleven astrometric epochs with a time baseline of over 56 years for the two components in the system, G 125-15 and G 125-14. Results: We derived M4.5V spectral types for both stars, confirmed their common proper motion, estimated the heliocentric distance and projected physical separation, determined the galactocentric space velocities, and deduced a most-probable age older than 600 Ma. We discovered that the primary, G 125-15, is in turn an inflated, double-lined, spectroscopic binary with a short period of photometric variability of P ~ 1.6 d, which we associated to orbital synchronisation. The observed X-ray and Halpha emissions, photometric variability, and abnormal radius and effective temperature of G 125-15 AB indicate strong magnetic activity, possibly due to fast rotation. Besides, the estimated projected physical separation between G 125-15 AB and G 125-14 of about 1200 AU makes WDS 19312+3607 to be one of the widest systems with intermediate M-type primaries. Conclusions: G 125-15 AB is a nearby (d ~ 26 pc), bright (J ~ 9.6 mag), active spectroscopic binary with a single proper-motion companion of the same spectral type at a wide separation. They are thus ideal targets for specific follow-ups to investigate wide and close multiplicity or stellar expansion and surface cooling due to reduced convective efficiency.

description: The photospheric spot activity of some of the stars with transiting planets discovered by the CoRoT space experiment is reviewed. Their out-of-transit light modulations are fitted by a spot model previously tested with the total solar irradiance variations. This approach allows us to study the longitude distribution of the spotted area and its variations versus time during the five months of a typical CoRoT time series. The migration of the spots in longitude provides a lower limit for the surface differential rotation, while the variation of the total spotted area can be used to search for short-term cycles akin the solar Rieger cycles. The possible impact of a close-in giant planet on stellar activity is also discussed.

description: Geant4 has an abundant set of physics models that handle the diverse interaction of particles with matter across a wide energy range. However, there are also many well established reaction codes currently used in the same fields where Geant4 is applied. One such code is the Ultra-relativistic Quantum Molecular Dynamics (UrQMD) model. In order to take advantage of the UrQMD code, we create a tool to enable comparisons among UrQMD and Geant4 hadronic models. This tool allows a user to process the output file of UrQMD through Geant4 toolkit, while at the same time, can choose among different Geant4 hadronic model generators. As an example, the UrQMD model is compared with the HARP-CDP experimental data and with the Binary and FRITIOF generators, in the framework of Geant4. It is shown that the UrQMD model can better reproduce charged pion production for p+Cu and Pb interactions at 3, 8 and 15 GeV/c, and is a good candidate for Geant4 hadronic models.

Strong-coupling approach to the Mott--Hubbard insulator on a Bethe lattice in Dynamical Mean-Field Theory

description: We calculate the Hubbard bands for the half-filled Hubbard model on a Bethe lattice with infinite coordination number up to and including third order in the inverse Hubbard interaction. We employ the Kato--Takahashi perturbation theory to solve the self-consistency equation of the Dynamical Mean-Field Theory analytically for the single-impurity Anderson model in multi-chain geometry. The weight of the secondary Hubbard sub-bands is of fourth order so that the two-chain geometry is sufficient for our study. Even close to the Mott--Hubbard transition, our results for the Mott--Hubbard gap agree very well with those from numerical Dynamical Density-Matrix Renormalization Group (DDMRG) calculations. The density of states of the lower Hubbard band also agrees very well with DDMRG data, apart from a resonance contribution at the upper band edge which cannot be reproduced in low-order perturbation theory.

description: We present a detailed study of the magnetic behavior of iron-oxide (gamma-Fe2O3 and Fe3O4) nanoparticles constituents of ferrofluids (FF's) with average particle sizes = 2.5 and 10 nm. The particles were dispersed in the frozen liquid carrier (pure FF) and in a frozen lyotropic liquid crystalline matrix in the nematic phase or ferronematic (FN) (ferrolyomesophase). Both FF and FN phases displayed superparamagnetic (SPM) behaviour at room temperature, with blocking temperatures T_B ~ 10 and 100 K for = 2.5 and 10 nm, respectively. Dynamic ac susceptibility measurements showed a thermally activated Néel-Brown dependence of the blocking temperature with applied frequency. Our results show that dipolar interactions are small, but non-negligible, as compared to the single-particle energy barriers from magnetic anisotropy. From the fit of ac susceptibility we calculated the effective magnetic anisotropy constant K_{eff} for 2.5 nm maghemite particles. Although interparticle interactions present in highly diluted samples do not appreciably modify the dynamic magnetic behavior of isolated particles, the calculated magnetic anisotropy were abut one order of magnitude larger that the bulk materials, suggesting the existence of large surface anisotropy. Using the thermally activated model to fit the dynamic data yielded effective energy barriers Ea = 3.5x10^{-21} J. From these data, we obtained K_{eff} = 422 kJ/m^3 for the single-particle effective magnetic anisotropy.

Clar Sextet Analysis of Triangular, Rectangular and Honeycomb Graphene Antidot Lattices

description: Pristine graphene is a semimetal and thus does not have a band gap. By making a nanometer scale periodic array of holes in the graphene sheet a band gap may form; the size of the gap is controllable by adjusting the parameters of the lattice. The hole diameter, hole geometry, lattice geometry and the separation of the holes are parameters that all play an important role in determining the size of the band gap, which, for technological applications, should be at least of the order of tenths of an eV. We investigate four different hole configurations: the rectangular, the triangular, the rotated triangular and the honeycomb lattice. It is found that the lattice geometry plays a crucial role for size of the band gap: the triangular arrangement displays always a sizable gap, while for the other types only particular hole separations lead to a large gap. This observation is explained using Clar sextet theory, and we find that a sufficient condition for a large gap is that the number of sextets exceeds one third of the total number of hexagons in the unit cell. Furthermore, we investigate non-isosceles triangular structures to probe the sensitivity of the gap in triangular lattices to small changes in geometry.
Application of a semiclassical model for the second-quantized many-electron Hamiltonian to nonequilibrium quantum transport: The resonant level model

description: A semiclassical (SC) approach is developed for nonequilibrium quantum transport in molecular junctions. Following the early work of Miller and White [J. Chem. Phys. 84, 5059 (1986)], the many-electron Hamiltonian in second quantization is mapped onto a classical model that preserves the fermionic character of electrons. The resulting classical electronic Hamiltonian allows for real-time molecular dynamics simulations of the many-body problem from an uncorrelated initial state to the steady state. Comparisons with exact results generated for the resonant level model reveal that a semiclassical treatment of transport provides a quantitative description of the dynamics at all relevant timescales for a wide range of bias and gate potentials, and for different temperatures. The approach opens a door to treating nontrivial quantum transport problems that remain far from the reach of fully quantum methodologies.

description: As a new model for signing quantum message, arbitrated quantum signature (AQS) has recently received a lot of attention. In this paper we study the cryptanalysis of previous AQS protocols from the aspects of forgery and disavowal. We show that in these protocols the receiver Bob can realize existential forgery of the sender's signature under known message attack. Bob can even achieve universal forgery when the protocols are used to sign a classical message. Furthermore, the sender Alice can successfully disavow any of her signatures by simple attack. The attack strategies are described in detail and some discussions about the potential improvements of the protocols are given. Finally we also present several interesting topics in future study on AQS protocols.

From a literary man to a model Confucian : Han Yu's image in the Tang anecdotes
Creators: name: Wu, Siyu
Publisher: name: University of British Columbia
Year: 2016

description: The early Northern Song witnesses the commencement of an elevation of Han Yu’s status in intellectual history. However, the image of Han Yu as a cultural hero established by the Northern Song intellectuals departs greatly from how Han Yu perceived himself and how he was perceived during his day. This paper examines how Han Yu was perceived by the Tang intellectuals after him by reading the anecdotes preserved in the five compilations produced during the 9th and 10th centuries: Wei Xuan’s Liu binke jiahualu, Li Zhao’s Guoshibu, Zhao Lin’s Yinhualu, Zhang Du’s Xuanshizhi and Wang Dingbao’s Zhiyan. This thesis argues that the Tang literati’s recognition of Han Yu’s commitment to some basic Confucian moral values proceeded gradually throughout the second half of the Tang dynasty. Contrary to Peter K. Bol’s assertion that the transformation of Han Yu’s image from a literary genius to a model Confucian took place after the Tang collapsed, the paper supplements Anna M. Shields’ speculation and contends that Han Yu’s understanding and practice of Confucius’ teaching, along with his literature, had increasingly drawn attention from the intellectual community by the late Tang period. Not only were Han Yu’s writings exalted, his consistent concern for public affairs, his stoic antagonism to Buddhism and Daoism, and his adherence to Confucian moral values in public and private life were also highlighted. Confronting unprecedented political depression and moral deficiency, the late Tang intellectual community portrayed Han Yu as a model Confucian, an image Han Yu could not imagine during his day.

description: A class of random graphs is introduced and studied. The graphs are constructed in an algorithmic way from five motifs which were found in [Milo R., Shen-Orr S., Itzkovitz S., Kashtan N., Chklovskii D., Alon U., Science, 2002, 298, 824-827]. The construction scheme resembles that used in [Hinczewski M., A. Nihat Berker, Phys. Rev. E, 2006, 73, 066126], according to which the short-range bonds are non-random, whereas the long-range bonds appear independently with the same probability. A number of structural properties of the graphs have been described, among which there are degree distributions, clustering, amenability, small-world property. For one of the motifs, the critical point of the Ising model defined on the corresponding graph has been studied.
