description: Motivated by experiments on non-magnetic triangular-lattice Mott insulators, we study one candidate paramagnetic phase, the columnar dimer (or valence-bond) phase. We apply variants of the bond-operator theory to a dimerized and spatially anisotropic spin-1/2 Heisenberg model and determine its zero-temperature phase diagram and the spectrum of elementary triplet excitations (triplons). Depending on model parameters, we find that the minimum of the triplon energy is located at either a commensurate or an incommensurate wavevector. Condensation of triplons at this commensurate-incommensurate transition defines a quantum Lifshitz point, with effective dimensional reduction which possibly leads to non-trivial paramagnetic (e.g. spin-liquid) states near the closing of the triplet gap. We also discuss the two-particle decay of high-energy triplons, and we comment on the relevance of our results for the organic Mott insulator EtMe3P[Pd(dmit)2]2.

description: We introduce a construction adding low-dimensional cells to a space that satisfies certain low-dimensional conditions; it preserves high-dimensional homology with appropriate coefficients. This includes as special cases Quillen's plus construction, Bousfield's integral homology localization, the existence of Moore spaces M(G,1) and Bousfield and Kan's partial k-completion of spaces. We also use it to generalize counterexamples to the zero-in-the-spectrum conjecture found by Farber and Weinberger, and by Higson, Roe and Schick.

title: Integrating In-Silico Models with In-Vitro Data to Generate Novel Insights into Biological Systems
Creators: name: Conway, D
Publisher: name: Liverpool John Moores University
Year: 2019

description: Models and computational predictions are useful in identifying certain key parameters that play a central role in defining the overall behavior of the system, and thus lead to new and more informative experiments. In this thesis, in-silico models are developed over a range of individual biological scales (macroscopic, mesoscopic and microscopic) for a range of cellular phenomena (cellular interactions, migration and signalling pathways) in order to highlight the importance of combined in-vitro – in-silico investigations. It is widely accepted that Systems Biology aims to provide a simpler and more abstract framework to explain complex biological phenomena. However, integration of these models with experimental data is often underutilised. Incorporation of experimentally derived data sets into the mathematical framework of in-silico modelling results in reliable, well parameterised systems capable of replicating dynamical properties of the biological systems. Work in this thesis includes the development of a continuous macroscopic in-silico model to identify the key mechanisms of interaction between cells present within the gastric tumour microenvironment. This model of discovery is used in a predictive capacity to accept or reject hypotheses. Next, the construction of a discrete cell based model of fibroblast migration is used to determine the degree of bias fibroblast cells experience when migrating over different surface topologies. The key results from this model show that particular surface topographies can have an effect on migratory cell behaviour. Then, the parameterisation of a differential equation model is used to quantify the key mechanisms of Nrf2 regulation in the cytoplasm and nucleus. Validation with experimentally derived datasets results in the quantification of rate ratios important to the dynamics of this signalling pathway. Finally, a stochastic Petri-net model capable of simulating the dynamical behaviour of functional cross-talk between the Nrf2 and NF-κB pathways is developed. This approach allows for the evaluation of a wide array of network responses, without the need for computationally expensive parameterisation. Together, these models exhibit how integration of in-silico models with in-vitro datasets can be used to generate new knowledge, or testable hypotheses.

Home away from home : an ethnographic study of the Taiwanese Canadians in Vancouver, with a focus on the early stage from the 1960s to the 1980s
Creators: name: Wu, Ren-Hung
Publisher: name: University of British Columbia
Year: 2012

description: This dissertation looks into the lives and experiences of early Taiwanese Canadians in Vancouver (1960s-1980s). The focus is particularly placed on how transnational migration experience has impacts on their self-image, national identity, and behaviours in the public sphere. An ethnographic research approach is taken to collect data of life histories through interviews, group interviews, and participatory observations in the community. It is found that early Taiwanese immigrants underwent enormous political pressure from their sending country. And this has in turn made Taiwanese immigrant community show a high degree of group solidarity and signs of radicalization over issues of identity politics. It is argued that the transnational social setting in the host society has engendered the chance for a reflexive examination of one’s national identity through interaction with the host society, the sending society, and other ethnic groups. And in particular it is also argued that the experience and the responding actions have led Taiwanese immigrants to proactively participate in public affairs. Theoretically the research broadens the understanding of conditions of nationalism by proposing a perspective giving transnational factors more weight in providing a framework for analysing complex phenomena of nation and nationhood in a rapidly transforming world.

description: A cluster analysis is applied to National Oceanic and Atmospheric Administration daily outgoing longwave radiation anomaly fields over the Intra‐American Seas, for the May to November rainy season 1980–2009. Seven recurrent convection regimes are identified, each with distinct impacts on local rainfall. Three suppressed‐convection regimes prevailing throughout the season and in particular during the Mid‐Summer Drought are related to transient anticyclonic circulation anomalies and broad drying over the region. The remaining regimes are all related to enhanced convection and cyclonic circulation anomalies over the Caribbean. For one wet regime, the cyclonic anomaly is located over Central America, which increases moisture advection from the eastern Pacific and in turn rainfall over Central and South America to the disadvantage of northern regions of the Caribbean. The three other regimes are associated with a weaker Caribbean Low Level Jet along its southern branch stretching along the South American coast, while its northern branch is strengthened, exposing the Caribbean to more moisture advection from the northeast trade winds, enhancing convection and rainfall locally. These three wet regimes are related to northwestward‐propagating convective cells that can be traced in a composite sense to the southward incursion of baroclinic waves from the midlatitudes, and anticyclonic wave breaking. In addition, their frequencies are found to be higher during phases 1 and 2 of the Madden‐Julian Oscillation, suggesting a connection with easterly waves emanating from African convection. Relationships are shown between these three northwestward‐propagating wet regimes and historical floods in the Caribbean illustrating the potential value of the convective regime approach for ultimately improving regional predictions and disaster early warning on sub‐seasonal scales.

description: No abstracts are to be cited without prior reference to the author.The Bering Ecosystem Study/Bering Sea Integrated Research Program (BEST-BSIERP) is a five-year programme involving over 90 principal investigators, jointly sponsored by the National Science Foundation (NSF) and the North Pacific Research Board (NPRB) to provide a synthesis of key hypotheses that govern the effects of climate on the Bering Sea ecosystem, and provide a set of tools for forecasting long-term production and distribution of marine resources (e.g. plankton, fish, birds, and mammals). A key component of this work is the FEAST model (Forage-Euphausiid Abundance in Space and Time) a three-dimensional, 10-km resolution model of fish and zooplankton of the Bering Sea built on the ROMS (Regional Oceanographic Model) platform. The fish component models size-based interactions between key fish and zooplankton species of the Bering Sea based on both the results of the BSIERP fieldwork and data from the collection of over 300 000 fish stomachs over the last 30 years in the region. The model includes a component for testing management strategies and for spatial prediction of fisheries and fish production given future climate (IPCC) scenarios as input drivers. Here, we show results of model predictions related to recent, present, and immediately future field conditions combined with data assimilation and validation. We focus on predictability using the wide range of resources at our disposal today. What is possible, what is missing, what predictions are robust, and what surprises we might have in store as we move to attempting to forecast longer term (20–50 year) outlooks for marine ecosystems?

description: We construct an action of the braid group B_{2g+2} on the free group F_{2g} extending an action of B_4 on F_2 introduced earlier by Reutenauer and the author. Our action induces a homomorphism from B_{2g+2} into the symplectic modular group Sp_{2g}(Z). In the special case g=2 we show that the latter homomorphism is surjective and determine its kernel, thus obtaining a braid-like presentation of Sp_4(Z).

description: The Post-9/11 GI Bill of 2008 has increased postsecondary education participation rates of military service members and veterans. Such participation is critical for military-connected individuals as they transition to civilian life. Postsecondary education enables military-connected individuals to upgrade their existing skills, gain new skills, or earn a credential that helps translate their skills into nonmilitary occupations. However, federal statistics indicate that while the Post-9/11 GI Bill has increased higher education participation rates overall, a higher percentage of veterans have entered for-profit colleges than have entered public institutions. In 2007–2008, 14 percent of veterans enrolled in college were at for-profit institutions, and 42 percent were at community colleges; by 2011–2012, these proportions had shifted to 24 percent and 37 percent, respectively.

description: As the main pathological basis for the development of cardiovascular and cerebrovascular diseases, atherosclerosis (AS) seriously affects human health. The key targets of biological information analysis of AS can help exploit therapeutic targets. The expression data of early and progressive atherosclerotic tissues were downloaded from the Gene Expression Omnibus (GEO) database. Based on GSE28829 and GSE120521, 74 key genes were obtained through differential expression analysis and weighted correlation network analysis (WGCNA) analysis, which were mainly enriched in the regulating of inflammatory response, chemokine signalling pathway, apoptosis, lipid and AS, Toll-like receptor signalling pathway and so on according to the results of the enrichment analysis. Cytoscape software was applied to screen four pivotal genes (TYROBP, ITGB2, ITGAM and TLR2) based on PPI. The results of the correlation analysis showed that the expression level of pivotal genes was positively related to macrophages M0, and was negatively related to T cells follicular helper. In addition, the expression of ITGB2 was positively related to Tregs. In this study, bioinformatics was applied to screen pivotal genes affecting the progress of AS, which were significantly related to immune-related biological functions and signal pathways of atherosclerotic tissues and the infiltration level of immune cells. Therefore, pivotal genes were expected to become therapeutic targets for AS.

description: We study the motion of a heavy tracer particle weakly coupled to a dense ideal Bose gas exhibiting Bose-Einstein condensation. In the so-called mean-field limit, the dynamics of this system approaches one determined by nonlinear Hamiltonian evolution equations describing a process of emission of Cerenkov radiation of sound waves into the Bose-Einstein condensate along the particle's trajectory. The emission of Cerenkov radiation results in a friction force with memory acting on the tracer particle and causing it to decelerate until it comes to rest.

description: Bounds are developed for the condition number of the linear finite element equations of an anisotropic diffusion problem with arbitrary meshes. They depend on three factors. The first, factor proportional to a power of the number of mesh elements, represents the condition number of the linear finite element equations for the Laplacian operator on a uniform mesh. The other two factors arise from the mesh nonuniformity viewed in the Euclidean metric and in the metric defined by the diffusion matrix. The new bounds reveal that the conditioning of the finite element equations with adaptive anisotropic meshes is much better than what is commonly feared. Diagonal scaling for the linear system and its effects on the conditioning are also studied. It is shown that the Jacobi preconditioning, which is an optimal diagonal scaling for a symmetric positive definite sparse matrix, can eliminate the effects of mesh nonuniformity viewed in the Euclidean metric and reduce those effects of the mesh viewed in the metric defined by the diffusion matrix. Tight bounds on the extreme eigenvalues of the stiffness and mass matrices are obtained. Numerical examples are given.

It is demonstrated that the suppression and broadening of the away side peak provide a unique signal for the onset of the saturation mechanism at small-$x$ in a large nucleus. We emphasize that future experiments of di-hadron correlations in $pA$ collisions at both RHIC and LHC, and in $eA$ collisions at the planned electron-ion collider, shall provide us with a thorough study and understanding of the strong interaction dynamics in the saturation regime.

Computational tools for CNV detection using probe-level analysis of Affymetrix SNP arrays : application to the study of CNVs in follicular lymphoma
Creators: name: Farnoud, Noushin
Publisher: name: University of British Columbia
Year: 2012

description: Copy number variants (CNVs) account for both variations among normal individuals and pathogenic variations. The introduction of DNA microarrays had a significant impact on the resolution of detectable CNVs and yielded a new perspective on the submicroscopic CNVs. Oligonucleotide microarrays, such as Affymetrix SNP arrays, have been commonly used for genome-wide CNV analysis. Despite the improvements in the technology, a major concern of using microarrays is how a putative CNV is defined. A disadvantage of oligonucleotide arrays is the poor signal-to-noise ratio of the data that leads to considerable variation in reported intensity readouts. Such variation will lead to false positive and false negative results, regardless of how the data are analysed. The most common approach to circumvent this problem is looking for abrupt ratio intensity shifts in several consecutive markers (e.g., SNP probes). However this approach reduces the overall resolution and mitigates the sensitivity of detecting CNVs with fewer probes. This limitation emphasizes the importance of designing methods that can identify noisy readouts at the probe-level. The main goals of this work were to study the scale of the variability in Affymetrix SNP arrays and to develop computational tools that can improve the resolution of CNV detection. By using simulated data, it was shown that the proposed method improved the accuracy and precision of detecting CNVs with fewer probes compared to standard methods. This approach was also applied to tumor/normal pairs from 25 follicular lymphoma patients and 286 candidate CNVs were found, from which 261 (91.2%) were also seen by other array-based method(s). Importantly, from 32 novel deletions, undetected by other array-based methods, at least 15 (47%) were real based on sequence-based validation. An example of a novel discovery was a partial deletion of the extracellular domain of the KIT proto-oncogene that may lead to constitutive activation of this gene. Gain of function mutations of KIT has been previously reported in several other hematologic cancers through other mechanisms such as point mutations. In conclusion, CNV discovery contributes to our understanding of complex diseases and the methods presented here should provide means for better detection of CNVs and their interpretation.

description: Classical potential energy calculations were performed for the dinucleoside phosphates UpA and GpC. Two widely accessible low-energy regions of conformation space were found for the w', w pair. That of lowest energy contains conformations similar to helical RNA, with w' and w in the vicinity of 300° and 280°, respectively. All five experimental observations of crystalline GpC, two of ApU, and the helical fragment of ApApA fall in this range. The second lowest region has w' and w at about 20° and 80°, respectively, which is in the general region of one experimentally observed crystalline conformer of UpA, and the nonhelical region of ApApA. It is concluded that GpC and ApU, which were crystallized as either sodium or calcium salts, are shielded from each other in the crystal by the water of hydration and are therefore free to adopt their predicted in vacuo minimum energy helical conformations. By contrast, crystalline UpA had only 1/2 water per molecule, and was forced into higher energy conformations in order to maximize intermolecular hydrogen bonding.

description: The unique linear and massless band structure of graphene, in a purely two-dimensional Dirac fermionic structure, have led to intense research spanning from condensed matter physics to nanoscale device applications covering the electrical, thermal, mechanical and optical domains. Here we report three consecutive first-observations in graphene-silicon hybrid optoelectronic devices: (1) ultralow power resonant optical bistability; (2) self-induced regenerative oscillations; and (3) coherent four-wave mixing, all at a few femtojoule cavity recirculating energies. These observations, in comparison with control measurements with solely monolithic silicon cavities, are enabled only by the dramatically-large and chi(3) nonlinearities in graphene and the large Q/V ratios in wavelength-localized photonic crystal cavities. These results demonstrate the feasibility and versatility of hybrid two-dimensional graphene-silicon nanophotonic devices for next-generation chip-scale ultrafast optical communications, radio-frequency optoelectronics, and all-optical signal processing.

description: Pseudo-holomorphic curves on almost complex manifolds have been much more intensely studied than their "dual" objects, the plurisubharmonic functions. These functions are defined classically by requiring that the restriction to each pseudo-holomorphic curve is subharmonic. In this paper subharmonic functions are defined by applying the viscosity approach to a version of the complex hessian which exists intrinsically on any almost complex manifold. Three theorems are proved. The first is a restriction theorem which establishes the equivalence of our definition with the "classical" definition. In the second theorem, using our "viscosity" definitions, the Dirichlet problem is solved for the complex Monge-Ampère equation in both the homogeneous and inhomogeneous forms. These two results are based on theorems found in two recent papers of the authors. Finally, it is shown that the plurisubharmonic functions considered here agree with the plurisubharmonic distributions. In particular, this proves a conjecture of Nefton Pali.
description: The result on the Dirichlet problem for the Monge-Ampere operator has been strengthened, and the exposition has been improved

description: This study examines the alignment of Indonesia’s open selection process for senior leadership with meritocratic principles and assesses the influence of sociopolitical factors on its outcomes. It also evaluates the effectiveness of the process in mitigating political interference, nepotism, and favoritism in public-sector appointments. Using a qualitative case study approach, data were collected through semi-structured interviews with 18 participants selected through convenience sampling, including senior public sector officials, policymakers, reform advocates, and rejected candidates. The findings reveal that while the early stages of the selection process, such as written tests and interviews, adhere to meritocratic ideals, political connections increasingly influence the later stages, undermining merit-based decisions. This shift reflects broader trends in developing countries, where political networks often outweigh meritocratic criteria in leadership appointments. This study highlights the need for stronger safeguards and oversight in the final stages of the process to ensure a truly merit-based system. Limitations include reliance on self-reported data and a regional focus on Sulawesi, which may limit generalizability. Future research should involve broader participant groups across regions and sectors to gain more comprehensive insight.
Strongly interacting one-dimensional bosons in arbitrary-strength optical lattices: from Bose-Hubbard to sine-Gordon and beyond

description: We analyze interacting one-dimensional bosons in the continuum, subject to a periodic sinusoidal potential of arbitrary depth. Variation of the lattice depth tunes the system from the Bose-Hubbard limit for deep lattices, through the sine-Gordon regime of weak lattices, to the complete absence of a lattice. Using the Bose-Fermi mapping between strongly interacting bosons and weakly interacting fermions, we derive the phase diagram in the parameter space of lattice depth and chemical potential. This extends previous knowledge from tight-binding (Bose-Hubbard) studies in a new direction which is important because the lattice depth is a readily adjustable experimental parameter. Several other results (equations of state, energy gaps, profiles in harmonic trap) are presented as corollaries to the physics contained in this phase diagram. Generically, both incompressible (gapped) and compressible phases coexist in a trap; this has implications for experimental measurements.
title: Analysis and Identification of biological production of Dimethyl Sulphide(DMS) and Dimethyl Sulponiopropionate(DMSP) by Phytoplankton in the Cochin Estuarine System (CES)

description: No abstracts are to be cited without prior reference to the author.The oceans emit sulphur to the marine boundary layer in the form of dimethyl sulphide (DMS), which is a non-sea salt sulphate compound. Recently progress has been made in the study of DMS in oceans because it is a major component of biogenically reduced sulphur compounds emitted from the surface ocean to the atmosphere. Seasonal studies, including pre-monsoon, monsoon, and post-monsoon, were carried out in the Cochin estuarine system. Phytoplankton and DMS samples were taken for qualitative and quantitative analysis. Physicochemical variables were also measured. Biological gaseous DMS is mainly produced by the decomposition of dimethyl sulfonio propionate (DMSP), which is produced by phytoplankton micro-organisms coccolithophores, phaeocystis, dinoflagellates, diatoms, etc. Our field data strongly suggest that DMS to DMSO (dimethyl sulfoxide) is an important process in our water column, and it is clear that considerable internal cycling in the DMSP/DMS/DMSO system occurs in the euphotic zone. Given that DMS is considered to be a major contributor to the greenhouse effect, the present work has a special significance in the study of the environment.

description: No abstracts are to be cited without prior reference to the author.Different age classes of fish usually do not experience the same rates of fishing mortality because fish size and behaviour change with age. Differential fishing mortality-at-age is usually described as selection or selectivity. Processes causing selectivity operate at the level of the fishing gear but also more broadly at the level of the population. In this paper, a relatively simple model of population-level selectivity is developed from a set of survival equations that are coupled to allow movement of fish between spatially distinct subpopulations. The model has a particularly surprising emergent property. Even though the same asymptotic gear-selectivity applies across all subpopulations, the overall population selectivity will be dome-shaped unless fishing mortality is uniform across all subpopulations. Hence, the sometimes-controversial feature of “cryptic biomass”, which follows from having domed selection, may be a natural consequence of the non-uniform application of fishing.
Alternative Conceptions of Poverty and their Implications for Income Maintenance

description: This paper speaks to the problem of designing income maintenance programs from the perspective of sociological theory. First, the underlying logic of situational and cultural theories of poverty is delineated, and some of their general implications are explored. Afterwards, the predictions of these theories with respect to the response by poor persons to an income maintenance program are examined. It is argued that, in place of seeking whether one or the other type of explanation is valid in general, we ascertain for which groups in poverty and for what types of response a particular theory is likely to be more useful. The discussion is illustrated by a consideration of how an individual's response to income maintenance is likely to vary with ethnicity and neighborhood organization.

description: We consider several aspects of high-order harmonic generation in solids: the effects of elastic and inelastic scattering; varying pulse characteristics; and inclusion of material-specific parameters through a realistic band structure. We reproduce many observed characteristics of high harmonic generation experiments in solids including the formation of only odd harmonics in inversion-symmetric materials, and the nonlinear formation of high harmonics with increasing field. We find that the harmonic spectra are fairly robust against elastic and inelastic scattering. Furthermore, we find that the pulse characteristics play an important role in determining the harmonic spectra.

Comments on Wanderer's Article on Riot Severity and its Correlates

Publisher: name: Columbia University
Year: 1970
Subjects: subject: Sociology
subject: FOS: Sociology

description: Spilerman's review of Wanderer concludes that his comparison with the Liberson and Silverman article is inappropriate on two accounts: the two studies investigated disturbances which occurred during different time periods and which were very different in form and perhaps in etiology as well, and the variables which Wanderer found to be correlated with riot severity are not the variables considered by Liberson and Silvernman. Overall, Spilerman continues his critique specifically regarding Wanderer's methodology and comparative conclusions. He also suggests that Wanderer's variables do not satisfy the reasoning.

description: We investigate theoretically the low energy physics of semiconductor Majorana wires in the vicinity of a magnetic field-driven topological quantum phase transition (TQPT). The local density of states (LDOS) at the end of the wire, which is directly related to the differential conductance in the limit of point-contact tunneling, is calculated numerically. We find that the dependence of the end-of-wire LDOS on the magnetic field is non-universal and that the signatures associated with the closing of the superconducting gap at the Majorana TQPT are essentially invisible within a significant range of experimentally relevant parameters. Our results provide an explanation for the recent observation of the apparent non-closure of the gap at the Majorana TQPT in semiconductor nanowires.

description: Social network platforms have transformed how people communicate and share information. However, as these platforms have evolved, the ability for users to control how and with whom information is being shared introduces challenges concerning the configuration and comprehension of privacy settings. To address these concerns, our crowd sourced approach simplifies the understanding of privacy settings by using data collected from 512 users over a 17 month period to generate visualizations that allow users to compare their personal settings to an arbitrary subset of individuals of their choosing. To validate our approach we conducted an online survey with closed and open questions and collected 59 valid responses after which we conducted follow-up interviews with 10 respondents. Our results showed that 70% of respondents found visualizations using crowd sourced data useful for understanding privacy settings, and 80% preferred a crowd sourced tool for configuring their privacy settings over current privacy controls.

description: Brucine and strychnine, primary bioactive constituents in traditional Chinese medicine, are extensively utilized in healthcare products due to their pharmacological and biochemical properties, including the enhancement of blood circulation, alleviation of cancer-related pain, and their anti-inflammatory and anti-angiogenesis effects. While brucine and strychnine possess indispensable pharmacological properties, they also pose serious toxicity and threats to human health. Consequently, it is imperative to develop reliable and sensitive methodologies for their pretreatment and quantification in various matrices. This comprehensive review encapsulates the prevailing pretreatment and analytical methodologies for brucine and strychnine in diverse samples from 2013 onwards. The routinely employed pretreatment techniques for target extraction and purification encompass liquid-liquid extraction, solid-phase extraction, and a range of microextraction methods. The determination strategies incorporate liquid chromatography-based methods, capillary electrophoresis methods, sensor methods, among others. Moreover, we have identified the strengths and weaknesses of each method and have forecast their future developmental prospects. Pretreatment and analysis methods for brucine and strychnine have been overviewed.Advantages and disadvantages of different methods have been compared.Different sensor methods for brucine and strychnine have been summarized.Future trends of pretreatment and analysis methods for brucine and strychnine have been discussed.
