description: We study the physical consequences of site dilution in Kitaev's honeycomb model, in both its gapped and gapless phases. We show that a vacancy binds a flux of the emergent $Z_2$ gauge field and induces a local moment. In the gapped phase this moment is free while in the gapless phase the susceptibility has the dependence $χ(h)\sim\ln(1/h)$ on field strength $h$. Vacancy moments have interactions that depend on their separation, their relative sublattice, and the phase of the model. Strikingly, in the gapless phase, two nearby vacancies on the same sublattice have a parametrically larger $χ(h)\sim(h[\ln(1/h)]^{3/2})^{-1}$. In the gapped phase, even a finite density of randomly distributed vacancies remains tractable, via a mapping to a bipartite random hopping problem. This leads to a strong disorder form of the low-energy thermodynamics, with a Dyson-type singularity in the density of states for excitations.

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.

description: We investigate the effect of electronic correlations onto the thermoelectricity of semi-conductors and insulators. Appealing to model considerations, we study various many-body renormalizations that enter the thermoelectric response. We find that, contrary to the case of correlated metals, correlation effects do not per se enhance the Seebeck coefficient or the figure of merit, for the former of which we give an upper bound in the limit of vanishing vertex corrections. For two materials of current interest, FeAs2 and FeSb2, we compute the electronic structure and thermopower. We find FeAs2 to be well described within density functional theory, and the therefrom deduced Seebeck coefficient to be in quantitative agreement with experiment. The capturing of the insulating ground state of FeSb2, however, requires the inclusion of many-body effects, in which we succeed by applying the GW approximation. Yet, while we get qualitative agreement for the thermopower of FeSb2 at intermediate temperatures, the tremendously large Seebeck coefficient at low temperatures is found to violate our upper bound, suggesting the presence of decisive (e.g. phonon mediated) vertex corrections.

description: We discuss the phase transition and critical exponents in the random allocation model (urn model) for different statistical ensembles. We provide a unified presentation of the statistical properties of the model in the thermodynamic limit, uncover new relationships between the thermodynamic potentials and fill some lacunae in previous results on the singularities of these potentials at the critical point and behaviour in the thermodynamic limit.
 The presentation is intended to be self-contained, so we carefully derive all formulae step by step throughout. Additionally, we comment on a quasi-probabilistic normalisation of configuration weights which has been considered in some recent studies

The pathogenesis of alopecia areata
Creators: name: Wang, Eddy Hsi Chun
Publisher: name: University of British Columbia
Year: 2015

description: The development of a hair loss disease, alopecia areata (AA), is believed to be associated with the initiation of an autoimmune response triggered by the activation of cytotoxic T-cells (CTLs) by unidentified autoantigen epitopes. The long-term sequelae of AA also have not received investigation beyond clinical observations. I hypothesized that CTLs in AA can be activated by autoantigen epitopes derived from hair follicle (HF) cells and activated CTLs may affect the viability of HF keratinocytes. Furthermore, I hypothesized the development of AA can have adverse effects on heart health and induce apoptosis of cardiomyocytes mediated in part by stress hormones. To test these hypotheses, I stimulated AA human peripheral blood mononuclear cells (PBMCs) and mouse LNCs with HF autoantigen epitope peptides. I showed that trichohyalin (TCHH) peptides induced higher frequencies of AA PBMC activation and led to keratinocyte apoptosis, while cytokeratin 16 (KRT16) peptides activate more AA mouse LNCs; both indicating the importance of keratinocyte autoantigens in AA pathogenesis. We showed that AA mice displayed significantly heavier hearts and collagen deposition in hearts compared to controls. Exposure of heart tissues to stress hormone adrenocorticotrophic hormone (ACTH) resulted in differential expression of interleukin-18 (Il18) genes and increased secretion of cardiac disease marker cardic troponin-I (cTnI). AA patients showed highest levels of cTnI compared to androgenetic alopecia (AGA) and no-hair-loss (NHL) groups. Culturing of cardiomyocytes with plasma from AA subjects with higher levels of cTnI also resulted in higher levels of apoptosis compared to cultures with plasma expressing low levels of cTnI; suggesting presence of harmful factors in the plasma. Additionally, to prove AA is a cell-mediated disease, we established a new mouse model of AA via injecting naïve C3H/HeJ mice with cultured LNCs isolated from spontaneously affected AA mice. In conclusion, AA pathogenesis is associated with higher frequencies of PBMC or LNC activation upon keratinocyte antigen epitope challenge and AA development resulted in changes in gene expression and heart morphology in mice and heart tissue remodeling markers in humans.

description: Capnia nigra (Pictet 1833) Pictet (1841) is reported to have received a somewhat aberrant specimen of C. nigra collected in the Taurus from the Vienna Museum. This old record can no longer be verified since the specimen under consideration is lost; but according to Zwick (1971) this record has nevertheless a certain probability. This supposed presence of C. nigra in Turkey is now confirmed by specimens collected in northern Anatolia. Material examined. West Erzincan, East Refahiye, above Alacaatli Koyu, 38°54'E / 39°53'N, 14-V-97, 3♀ (Vinçon coll.). Ecology. Eurytopic species occurring in various types of mountain and foothill water courses. The adults emerge in winter and spring. Distribution. Eurasiatic. In the Anatolian Peninsula, it is reported from the Taurus (Pictet 1841) and the central Pontic Mountains. It also occurs in the Caucasus and Armenia (Fig. 12).

description: Using the 32-m Medicina, 45-m Nobeyama, and 100-m Effelsberg telescopes we found a statistically significant velocity offset Delta V = 27 +/- 3 m/s (1sigma) between the inversion transition in NH3(1,1) and low-J rotational transitions in N2H+(1-0) and HC3N(2-1) arising in cold and dense molecular cores in the Milky Way. Systematic shifts of the line centers caused by turbulent motions and velocity gradients, possible non-thermal hyperfine structure populations, pressure and optical depth effects are shown to be lower than or about 1 m/s and thus can be neglected in the total error budget. The reproducibility of Delta V at the same facility (Effelsberg telescope) on a year-to-year basis is found to be very good. Since the frequencies of the inversion and rotational transitions have different sensitivities to variations in mu = m_e/m_p, the revealed non-zero Delta V may imply that mu changes when measured at high (terrestrial) and low (interstellar) matter densities as predicted by chameleon-like scalar field models - candidates to the dark energy carrier. Thus we are testing whether scalar field models have chameleon-type interactions with ordinary matter. The measured velocity offset corresponds to the ratio Delta mu/mu = (mu_space - mu_lab)/mu_lab of (26 +/- 3)x10^{-9} (1sigma).

description: In materials like transition metals oxides where electronic Coulomb correlations impede a description in terms of standard band-theories, the application of genuine many-body techniques is inevitable. Interfacing the realism of density-functional based methods with the virtues of Hubbard-like Hamiltonians, requires the joint ab initio construction of transfer integrals and interaction matrix elements (like the Hubbard U) in a localized basis set. In this work, we employ the scheme of maximally localized Wannier functions and the constrained random phase approximation to create effective low-energy models for Manganese monoxide, and track their evolution under external pressure. We find that in the low pressure antiferromagnetic phase, the compression results in an increase of the bare Coulomb interaction for specific orbitals. As we rationalized in recent model considerations [Phys. Rev. B 79, 235133 (2009)], this seemingly counter-intuitive behavior is a consequence of the delocalization of the respective Wannier functions. The change of screening processes does not alter this tendency, and thus, the screened on-site component of the interaction - the Hubbard U of the effective low-energy system - increases with pressure as well. The orbital anisotropy of the effects originates from the orientation of the orbitals vis-a-vis the deformation of the unit-cell. Within the high pressure paramagnetic phase, on the other hand, we find the significant increase of the Hubbard U is insensitive to the orbital orientation and almost exclusively owing to a substantial weakening of screening channels upon compression.

Scalable Imaginary Time Evolution with Neural Network Quantum States

description: The representation of a quantum wave function as a neural network quantum state (NQS) provides a powerful variational ansatz for finding the ground states of many-body quantum systems. Nevertheless, due to the complex variational landscape, traditional methods often employ the computation of quantum geometric tensor, consequently complicating optimization techniques. Contributing to efforts aiming to formulate alternative methods, we introduce an approach that bypasses the computation of the metric tensor and instead relies exclusively on first-order gradient descent with Euclidean metric. This allows for the application of larger neural networks and the use of more standard optimization methods from other machine learning domains. Our approach leverages the principle of imaginary time evolution by constructing a target wave function derived from the Schrödinger equation, and then training the neural network to approximate this target. We make this method adaptive and stable by determining the optimal time step and keeping the target fixed until the energy of the NQS decreases. We demonstrate the benefits of our scheme via numerical experiments with 2D J1-J2 Heisenberg model, which showcase enhanced stability and energy accuracy in comparison to direct energy loss minimization. Importantly, our approach displays competitiveness with the well-established density matrix renormalization group method and NQS optimization with stochastic reconfiguration.

description: The method proposed by Pratt to derive recursion relations for systems of degenerate fermions [Phys. Rev. Lett. 84, 4255 (2000), arXiv:nucl-th/9905055] relies on diagrammatic techniques. This efficient formalism assumes no explicit two-body interactions, makes possible the inclusion of conservation laws and requires low computational time. In this brief report, we show that such recursion relations can be obtained from generating functions, without any restriction as concerns the number of conservation laws (e.g. total energy or angular momentum).

Three-dimensional nonlinear analysis of dynamic soil-pile-structure interaction for bridge systems under earthquake shakings
Creators: name: Rahmani, Amin
Publisher: name: University of British Columbia
Year: 2015

description: Bridge designers have adopted simple approximate methods to take into account soil-structure-interaction (SSI) in dynamic analysis of bridge systems. The most popular one is the substructuring method in which the response of the foundation soil and its interaction with the pile foundation and the abutment system are represented by a set of one-dimensional springs and dashpots. While this method has been widely used in practice, it has never been validated by comparing the results with those obtained from full-scale analyses. This thesis aims to evaluate the substructuring method and to quantify the level of associated errors for the use in bridge engineering. To this end, the baseline data required for the evaluation process is provided by full-scale nonlinear dynamic analysis of the bridge systems subjected to earthquake shaking using continuum modeling method. This involves detailed modeling of the foundation soil, pile foundations, abutment system, and the whole bridge structure. Three representative bridge systems with two, three, and nine spans are simulated. In all models, nonlinear hysteretic response of the foundation soil and the bridge piers are accounted for in the analyses using advanced constitutive models. The numerical model of the bridge is validated by simulating the seismic response of the Meloland Road Overpass for which extensive measured data exist over past earthquake events. Subsequently each one of the three bridge systems is also simulated using the substructuring method. Comparing the obtained results with the baseline data indicates that the substructure model may not be sufficiently reliable in predicting the bridge response. In particular the method is shown to misrepresent the spectral responses of the bridge, pier deflections, shear forces and bending moments induced at the pier base, and longitudinal and transverse forces induced to the abutments. The substructuring method is shown to suffer from several fundamental drawbacks that cannot be simply resolved. Using the recent advances in constitutive modeling of geotechnical and structural materials, and in computational tools and high-performance parallel computing, this thesis shows that large-scale continuum models can gradually become a powerful and significantly more reliable alternative for proper modeling of seismic SSI in bridge engineering.

description: This paper presents a systematic cataloging of the generators of celestial symmetries on phase space. Starting from the celestial OPEs, we first show how to extract a representation of the general-spin analog of the wedge subalgebra of $w_{1+\infty}$ on the phase space of massless matter fields of arbitrary helicity. These generators can be expressed as light-sheet operators that are quadratic in the matter fields at future or past null infinity. We next show how to extend these symmetries beyond the wedge. Doing so requires us to augment the quadratic operators with: 1) linear terms corresponding to primary descendants of the negative helicity gauge fields the matter modes couple to, and 2) a tower of higher-particle composite operator contributions. These modes can be realized as light-ray operators supported on generators of null infinity, but local on the celestial sphere. Finally, we construct a representation of the celestial symmetries that captures how the positive helicity gauge fields transform. We close by discussing how these celestial symmetries inform our choice of detector operators.

description: The energy relaxation of carriers in reduced graphene oxide thin films is studied using optical pump-probe spectroscopy with two probes of different colors. We measure the time difference between peaks of the carrier density at each probing energy by measuring a time-resolved differential transmission and find that the carrier density at the lower probing energy peaks later than that at the higher probing energy. Also, we find that the peak time for the lower probing energy shifts from about 92 to 37 fs after the higher probing energy peak as the carrier density is increased from 1.5E12 to 3E13 per square centimeter, while no noticeable shift is observed in that for the higher probing energy. Assuming the carriers rapidly thermalize after excitation, this indicates that the optical phonon emission time decreases from about 50 to about 20 fs and the energy relaxation rate increases from 4 to 10 meV/fs. The observed density dependence is inconsistent with the phonon bottleneck effect.

description: The accurate measurement of Passive intermodulation (PIM) generated from RF radiating components requires an interference-free environment. The anechoic chamber environment is a suitable option to avoid any external interference that may disturb the PIM measurement. However, RF absorbers in anechoic chambers can be a potential source of PIM and thus affect the measurement accuracy. This paper presents a detailed evaluation of PIM performance for five kinds of absorbers from different manufacturers. It is confirmed that some RF absorbers can be a potential source of PIM. The obtained results show that the conductive carbon material used in fabricating the WAVASORB® VHP-8 absorber, EHP- 5PCL absorber and MWA-LFA produces low level of PIM. The nano-metal films incorporated inside Frankonia absorber produces lower PIM compared to carbon-made absorbers. Lastly, the absorber made from EVU material (dry mix of cellulose materials, carbon fibers and other components) produces a higher PIM level.

description: Observations of the water inventory as well as other chemically important species on Jupiter will be performed in the frame of the guaranteed time key project of the Herschel Space Observatory entitled "Water and related chemistry in the Solar system". Among other onboard instruments, PACS (Photodetector Array Camera and Spectrometer) will provide new data of the spectral atlas in a wide region covering the far-infrared and submillimetre domains, with an improved spectral resolution and a higher sensitivity compared to previous observations carried out by Cassini/CIRS (Composite InfraRed Spectrometer) and by ISO (Infrared Space Observatory). In order to optimise the observational plan and to prepare for the data analysis, we have simulated the expected spectra of PACS Jupiter observations. Our simulation shows that PACS will promisingly detect several H2O emission lines. As PACS is capable of spatially resolving the Jovian disk, we will be able to discern the external oxygen sources in the giant planets by exploring the horizontal distribution of water. In addition to H2O lines, some absorption lines due to tropospheric CH4, HD, PH3 and NH3 lines will be observed with PACS. Furthermore, owing to the high sensitivity of the instrument, the current upper limit on the abundance of hydrogen halides such as HCl will be also improved.

description: The desire to put one’s interest above another’s is only human, but more often than not this leads to conflicts which must be resolved. Dispute resolution is at the heart of legal practice and has often meant one thing—litigation! This paper examines the role the law has played in making litigation the dominant form of dispute resolution in Ghana. It also looks at how legal education in Ghana, and the attitudes of lawyers and lay persons have contributed to making litigation more popular. The authors propose the minimization of the role of litigation in conflict resolution as Alternative Dispute Resolution (ADR) Mechanisms are to be preferred for so many reasons. An attempt is also made to assess the effects of a merger of Alternative Dispute Resolution Mechanisms and Litigation within the Ghana legal system.

description: Given a non-oscillating gradient trajectory G of a real analytic function f, we show that the limit v of the secants at the limit point O of G along the trajectory G is an eigen-vector of the limit of the direction of the Hessian matrix Hess (f) at O along G. The same holds true at infinity if the function is globally subanalytic. We also deduce some interesting estimates along the trajectory.

description: In this paper, we propose a sub-Nyquist sampling (SNS) orthogonal frequency-division multiplexing (OFDM) radar system capable of reducing the analog-to-digital converter (ADC) sampling rate in OFDM radar without any additional manipulations of its hardware and waveform. To this end, the proposed system utilizes the ADC sampling rate of B/L to sample the received baseband signal with a bandwidth of B, where L is a positive proper divisor of the number of subcarriers. This divides the baseband signal into L sub-bands, folding into a sub-Nyquist frequency band due to aliasing. By leveraging known modulation symbols of the transmitted signal, the folded signal can be unfolded to the full-band signal. This allows an estimation of target ranges with the range resolution of the full signal bandwidth B without the degradation of the maximum unambiguous range. During the signal-unfolding process, the signals from other sub-bands remain as symbol-mismatch noise (SMN), which significantly degrades the signal-to-noise ratio (SNR) of the detected targets. It also causes weaker targets to be submerged under the noise in range profiles. To resolve this, a symbol-mismatch noise cancellation (SMNC) technique is also proposed, which reconstructs the interfering signals from the other sub-bands using the detected targets and subtracts them from the unfolded signal. As a result, the proposed sub-Nyquist sampling OFDM radar and corresponding signal processing technique enable a reduction in the ADC sampling rate by the ratio of L while incurring only a 10 log10 L increase in the noise due to noise folding. This is validated through simulations and measurements with various sub-sampling ratios.

description: We present a comprehensive study of generalized Wigner crystals across various filling factors for system sizes up to 162 holes employing Hartree-Fock theory and explicitly correlated wave function approaches. While we find broad agreement with the behavior observed in experiments and classical Monte Carlo simulations, we highlight the fact that the Hartree-Fock energy landscape appears to be remarkably complex, exhibiting many competing states, both ordered and disordered, separated by energies of a fraction of $\sim$ 1 meV/hole. We demonstrate which of the located states are metastable by performing a stability analysis at the Hartree-Fock level. Correlated wave function methods furthermore reveal small correlation energies that are nevertheless large enough to tip the balance of state ordering found within Hartree-Fock theory.

Unveiling the neglected roles of nucleoprotein NLS2 and cellular vimentin during Influenza A virus infection
Creators: name: Wu, Wei
Publisher: name: University of British Columbia
Year: 2016

description: Influenza A virus exploits the cellular transport machinery during the early stages of infection. It enters cells by endocytosis and takes advantage of the endocytic trafficking to move towards the perinuclear region with the assistance of actin filaments and microtubules. A recent proteomic study identified vimentin as a putative interacting protein of influenza viral components. However, the role of vimentin during influenza A infection has not yet been determined. After endocytosis, the viral ribonucleopotein complexes (vRNPs), containing the RNA viral genome, the viral polymerases, and several copies of nucleoprotein, are released from late endosomes and enter the nucleus for replication. Two nuclear localization sequences (NLSs), NLS1 and NLS2, on nucleoprotein mediate the nuclear import of vRNPs. The function of NLS1 has been well studied, however, the role of NLS2 remains to be defined. This thesis has two major aims: to characterize the function of NLS2 and to determine the role of vimentin during influenza infection. For the first aim, I use a chimeric protein (5GFP) fused to NLS2, in combination with RNAi of several importin α isoforms and biochemical assays, and found that NLS2 is able to mediate the nuclear import of 5GFP by interacting with importin α1, α3, α5, and α7. NLS2 contains only a single amino acid difference at position 17 between different strains of influenza A virus, which could be either lysine (K) or arginine (R). I found that NLS2K induces more nuclear accumulation of 5GFP than NLS2R. Using site-directed mutagenesis I demonstrated that NLS2K contains two independent functional basic clusters, while NLS2R only has one. Moreover, my study also revealed that inhibiting the function of NLS1 and NLS2 impairs the nuclear import of vRNPs and further inhibits viral infection. For the second aim I followed influenza A virus infection in both vimentin null cells and vimentin RNAi knock-down cells, and found that vimentin plays a role in releasing vRNPs from endosomes. In summary, my work dissects the basic mechanisms involved in influenza A virus endocytic trafficking and nuclear import, which provide us with better insights into the viral-host interaction during influenza A virus infection.

description: Studying the nature and origin of the intergalactic magnetic field (IGMF) is an outstanding problem of cosmology. Measuring Faraday rotation would be a promising method to explore the IGMF in the large-scale structure (LSS) of the universe. We investigated the Faraday rotation measure (RM) due to the IGMF in filaments of galaxies using simulations for cosmological structure formation. We employed a model IGMF based on turbulence dynamo in the LSS of the universe; it has an average strength of $< B > \sim 10$ nG and a coherence length of several $\times\ 100\ h^{-1}$ kpc in filaments. With the coherence length smaller than path length, the inducement of RM would be a random walk process, and we found that the resultant RM is dominantly contributed by the density peak along line of sight. The rms of RM through filaments at the present universe was predicted to be $\sim 1\ {\rm rad\ m^{-2}}$. In addition, we predicted that the probability distribution function of $|{\rm RM}|$ through filaments follows the log-normal distribution, and the power spectrum of RM in the local universe peaks at a scale of $\sim 1\ h^{-1}$ Mpc. Our prediction of RM could be tested with future instruments.

Holotype ♂, North Carolina: Robeson Co., Raft Swamp, Old Lowery Rd @ bridge, 2 mi E Red Springs, 2 May 2003, B. Kondratieff & R. F. Kirchner. Paratype: Same data as Holotype, 1♂. The Holotype is deposited at the National Museum of Natural History, Smithsonian Institution, Washington, D. C and the paratype ♂ in the C.P. Gillette Museum of Arthropod Diversity, Colorado State University. Male. Forewing length 12 mm. General body color light yellow to yellow-brown. Head yellow except for brown quadrangular area over ocelli and brown triangular area forward of median ocellus, prothorax brown with a slight dark sutural line (Fig. 1). Wings light amber, veins brown. Femora with a distinct apical black transverse band. Abdomen yellowish with brown posterior patches. Tergum 10 mesal sclerite brown, not divided, sensilla basiconica sparse (Fig. 2). Paraproct broad of medium length, with small tooth obscure in lateral view (Figs. 3), in caudal view, medium length, truncate at apex with the tooth at upper lateral margin (Figs. 4, 5). Penis tube + sac long, caecum small, wider than long; lateral sclerite weakly developed; dorsal patch broad basally covering most of tube surface (Figs. 6, 7). Female. Unknown. Egg. Unknown. Etymology. The patronym honors Steven R. Beaty, Environmental Biologist, North Carolina Division of Water Quality. His on-going efforts to associate the adult and immature stages of North Carolina aquatic insects are noteworthy. Diagnosis. The male of the new species can be immediately distinguished from all other known described Perlesta by the broad truncate paraprocts with a small lateral tooth (Figs. 2-5). The authors were reluctant to describe this species because of the lack of positively associated females with mature eggs, but the male paraprocts are so distinctive that the males cannot be confused with any other described North American species.
