description: We prove an equivalence between the Bryan--Steinberg theory of $π$-stable pairs on $Y = \mathcal{A}_{m-1} \times \mathbb{C}$ and the theory of quasimaps to $X = \mathrm{Hilb}(\mathcal{A}_{m-1})$, in the form of an equality of K-theoretic equivariant vertices. In particular, the combinatorics of both vertices are described explicitly via box counting. Then we apply the equivalence to study the implications for sheaf-counting theories on $Y$ arising from 3d mirror symmetry for quasimaps to $X$, including the Donaldson--Thomas crepant resolution conjecture.

description: Abstract: Clustering is widely used as a knowledge discovery method in scientific studies but is not often used in architectural research. This paper applies clustering to a dataset of 129 residential layouts, which were collected from contemporary architectural practices, to reveal underlying design patterns. To achieve this, this paper introduces a novel measure for the topological properties of layouts: ‘grating difference measure’. It was benchmarked against an alternative that measures geometrical properties and the advantages are explained. The grating difference measure indicates the extent of design differences, which is used in the clustering method to obtain the distance between datapoints. The results from clustering were grouped into design schematics and qualitatively assessed, showing a convincing separation of characteristics. The method demonstrated in this paper may be used to reveal topological patterns in datasets of existing designs for both academic and practical purposes.

description: We consider a self-consistent system of Bianchi type-I (BI) gravitational field and a binary mixture of perfect fluid and dark energy given by a cosmological constant. The perfect fluid is chosen to be the one obeying either the usual equation of state, i.e., $p = ζ\ve$, with $ζ\in [0, 1]$ or a van der Waals equation of state. Role of the $Λ$ term in the evolution of the BI Universe has been studied.

Quantum key distribution with non-ideal heterodyne detection: composable security of discrete-modulation continuous-variable protocols
Creators: name: Lupo, Cosmo
name: Ouyang, Yingkai
Publisher: name: arXiv
Year: 2021
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: Continuous-variable quantum key distribution exploits coherent measurements of the electromagnetic field, i.e., homodyne or heterodyne detection. The most advanced security proofs developed so far relied on idealised mathematical models for such measurements, which assume that the measurement outcomes are continuous and unbounded variables. As physical measurement devices have finite range and precision, these mathematical models only serve as an approximation. It is expected that, under suitable conditions, the predictions obtained using these simplified models are in good agreement with the actual experimental implementations. However, a quantitative analysis of the error introduced by this approximation, and of its impact on composable security, have been lacking so far. Here we present a theory to rigorously account for the experimental limitations of realistic heterodyne detection. We focus on collective attacks, and present security proofs for the asymptotic and finite-size regimes, the latter within the framework of composable security. In doing this, we establish for the first time the composable security of discrete-modulation continuous-variable quantum key distribution in the finite-size regime. Tight bounds on the key rates are obtained through semi-definite programming and do not rely on a truncation of the Hilbert space.

description: The fact that wineries tend to cluster in certain sub-regions can be partially explained by the terroir of those areas. However, a gap in our understanding of the spatial relationships among wineries remains. In this article, winery-level data with geographic information system (GIS) coordinates are utilized to examine the spatial relationships among neighboring wineries. Spatial effects for the California and Washington wine industries are assessed by performing clustering tests based on wine prices and tasting scores. A spatial lag model is then estimated to test the hypothesis that there are positive effects from neighbors when analyzing the hedonic price equations. The regression results indicate that there exists strong and positive neighbor effect.

description: Computational determination of the equilibrium state of heterogeneous phospholipid mem-branes is a significant challenge. We wish to explore the rich phase diagram of these multi-component systems. However, the diffusion and mixing times in membranes are long com-pared to typical times of computer simulations. To speed up the relaxation times, advanced simulation methods are used. We evaluate the combination of enhanced sampling tech-niques such as MDAS (Molecular Dynamics with Alchemical Steps) and MC-MD (Monte Carlo with Molecular Dynamics) with a coarse-grained model of membranes (Martini) to re-duce the number of steps and force evaluations that are needed to reach equilibrium. We illustrate a significant gain compared to straightforward Molecular Dynamics of the Martini model by factors between three to ten. The combination is a useful tool to enhance the study of phase separation and the formation of domains in biological membranes.
The characterization and significance of the complement system activated by photodynamic therapy in the treatment of solid tumors
Creators: name: Cecic, Ivana Katarina
Publisher: name: University of British Columbia
Year: 2009

description: Photodynamic therapy (PDT) is approved by health agencies throughout the developed world for the treatment of a variety of diseases, and continues to gain recognition as a treatment for neoplastic lesions. During PDT a light-sensitive drug (photosensitizer) is excited locally in tissue with light of appropriate wavelength. The transfer of energy from the excited photosensitizer to molecular oxygen (O2) results in the production of reactive oxygen species (ROS) that inflict damage to various cell components resulting in the disruption of tissue homeostasis. The aim of this project was to ascertain whether the complement (C) system is engaged in a PDT-treated solid tumor and if this plays a role in overall tumor response to treatment. The following summarizes the findings of this dissertation. C activation in response to PDT-inflicted tumor injury proceeds via the antibody-independent alternative pathway and results in significantly elevated levels of the fluid phase C protein C3 in both serum and Lewis lung carcinoma tumors. Other indications of C activity are the presence of the C3 breakdown fragment C3b and assembly of the membrane-inserted complex containing proteins C5b through C9. In mice bearing PDT-treated EMT6 tumors, a multitude of signals are released from the treated lesion into circulation to promote immune cell trafficking. Although a variety of inflammatory mediators such as IL-1β, IL-6, TNF-α, and histamine promote neutrophilia in mice following PDT the most significant effect was demonstrated by C. Blocking C activity prior to PDT also resulted in a significant decrease in tumor cures. A C3 knockout model (C3 k.o.) was employed to address the impact of the loss of C function on the long-term control of Lewis lung carcinoma tumors by PDT. Results suggest that the relevance of C activity may depend on the mechanism of action of the photosensitizer of choice and subsequent levels of tumor oxygen during light activation. Enhanced tumor O2 levels during treatment theoretically increased the probability of ROS production. Understanding the mechanism of how the C system responds to PDT-induced injury could lead to methods of improving the overall therapeutic benefit of treatment and gain wider acceptance for clinical applications.

description: This study used 30 years of continuous data for 135 farms in Kansas to explore changes in productivity using Malmquist productivity indices. The indices were used to determine whether there was productivity convergence or divergence in Kansas farms. The results showed that there was significant divergence among the farms and not a tendency for farms to catch-up to the same levels of productivity as the top farms in the sample. The average annual productivity growth over the sample period, 1979-2008, was 0.50 percent. The top farms based on MPI were larger in terms of value of farm production, crop farm income and livestock farm income and received a larger percentage of their income from oilseeds, feed grains, and swine than the other farms on average and relatively less of their income from small grains.

description: In this paper we study the dynamics of eigenvalues of the deformation tensor for solutions of the 3D incompressible Euler equations. Using the evolution equation of the $L^2$ norm of spectra, we deduce new a priori estimates of the $L^2$ norm of vorticity. As an immediate corollary of the estimate we obtain a new sufficient condition of $L^2$ norm control of vorticity. We also obtain decay in time estimates of the ratios of the eigenvalues. In the remarks we discuss what these estimates suggest in the study of searching initial data leading to a possible finite time singularities. We find that the dynamical behaviors of $L^2$ norm of vorticity are controlled completely by the second largest eigenvalue of the deformation tensor.

description: Food safety issues often arise from problems of asymmetric information between consumers and suppliers with regards to product-specific attributes. Severe food safety scandals were observed recently in China that not only caused direct economic and life loss but also created distrust in the Chinese food system domestically as well as internationally. While much attention has focused on the problems plaguing the Chinese government’s food inspection system, little research has been dedicated to analyze consumers’ concerns over food safety. In this paper we measure consumer preferences for select food safety attributes in pork and take their food safety risk perceptions into account. Several choice experiment models, including latent class and random parameters logit, are constructed to capture heterogeneity in consumer preferences. A statistical sample of 6,720 observations is obtained from a choice experiment administered in seven major Chinese metropolitan cities. Our results suggest that Chinese consumers have the highest willingness-to-pay for a government certification program, followed by a traceability system, third party certification and a product-specific information label. The results of this study call upon the direct involvement of the Chinese government in the food safety system. A more strict monitoring system will not only improve consumer welfare in the short-run but also restore consumers’ trust leading to a social welfare increase in the long run.

description: The aim of this paper is to study the Wold-type decomposition in the class of $m$-isometries. One of our main results establishes an equivalent condition for an analytic $m$-isometry to admit the Wold-type decomposition for $m\ge2$. In particular, we introduce the $k$-kernel condition which we use to characterize analytic $m$-isometric operators which are unitarily equivalent to unilateral operator valued weighted shifts for $m\ge2$. As a result, we also show that $m$-isometric composition operators on directed graphs with one circuit containing only one element are not unitarily equivalent to unilateral weighted shifts. We also provide a characterization of $m$-isometric unilateral operator valued weighted shifts with positive and commuting weights.

description: Abstract: This paper introduces the use of graph theory for the study of the work of Candilis–Josic–Woods. Α short introduction to the architects’ main strategies as members of Team Χ and CIAM (Congrès Internationaux d’Architecture Moderne) critics is given. Geometry and computational design methods for city planning and design are briefly discussed. Definitions of the minimum spanning tree, the shortest walk tree and the Steiner tree are then developed. The research projects these methods onto the main principles of Candilis–Josic–Woods’ planning and urban design approach to reinforce their strategic concepts. Distance-related and proximity-based ideas and their importance are sought in the literature related to Candilis–Josic–Woods’ body of work. Algorithmic based examples approximating a Euclidean Steiner tree are shown and discussed in the context of Candilis–Josic–Woods’ syntax. This paper argues that the generation of additional points through the use of a Euclidean Steiner tree algorithmic process is of importance in the work of Candilis–Josic–Woods as it allows for a systematic but emerging creation of hubs that can be activated as space on the one hand, and facilitate pedestrian circulation on the other. The project seeks to demonstrate the relevance of the triplet’s design methods to today’s complex networks of urban environments.

A 1200 acre model crop farm was constructed to conduct the farm management budget and simulation analyses. Results indicate: (1) the CT rotation had the highest average net returns, (2) Several four-crop no-till rotations were preferred as producer risk aversion increased, and (3) carbon credit payments would need to be $14 to $36 per acre for the top four NT rotations to be as profitable as the CT rotation.

description: We present a density-matrix rate-equation approach to sequential tunneling through a metal particle weakly coupled to ferromagnetic leads. The density-matrix description is able to deal with correlations between degenerate many-electron states that the standard rate equation formalism in terms of occupation probabilities cannot describe. Our formalism is valid for an arbitrary number of electrons on the dot, for an arbitrary angle between the polarization directions of the leads, and with or without spin-orbit scattering on the metal particle. Interestingly, we find that the density-matrix description may be necessary even for metal particles with unpolarized leads if three or more single-electron levels contribute to the transport current and electron-electron interactions in the metal particle are described by the `universal interaction Hamiltonian'.

description: The weak commutativity group $χ(G)$ is generated by two isomorphic groups $G$ and $G^{φ}$ subject to the relations $[g,g^φ]=1$ for all $g \in G$. The group $χ(G)$ is an extension of $D(G) = [G,G^φ]$ by $G \times G$. We prove that if $G$ is a finite solvable group of derived length $d$, then $\exp(D(G))$ divides $\exp(G)^{d}$ if $|G|$ is odd and $\exp(D(G))$ divides $2^{d-1}\cdot \exp(G)^{d}$ if $|G|$ is even. Further, if $p$ is a prime and $G$ is a $p$-group of class $p-1$, then $\exp(D(G))$ divides $\exp(G)$. Moreover, if $G$ is a finite $p$-group of class $c\geq 2$, then $\exp(D(G))$ divides $\exp(G)^{\lceil \log_{p-1}(c+1)\rceil}$ ($p\geq 3$) and $\exp(D(G))$ divides $2^{\lfloor \log_2(c)\rfloor} \cdot \exp(G)^{\lfloor \log_2(c)\rfloor+1}$ ($p=2$).

description: This doctoral thesis is dedicated to the multidisciplinary exploration of the diverse applications of diamonds, harnessing their exceptional physical and chemical properties. Diamonds, characterized by their unique attributes, exhibit immense potential across various scientific domains and industrial sectors. The research in this thesis commenced with an extensive investigation into diamond growth technique s, with a primary focus on chemical vapor deposition (CVD). Through this method, we succeeded in expanding the spectrum of synthesized diamonds, both in terms of quality and size, thereby opening up new avenues for their utilization across a myriad of appl ications. The outcomes of this research have significantly broadened the applicability of diamonds in diverse fields such as electronics, optics, thermal management, life sciences, and materials science. Subsequently, our attention turned towards the devel opment of marine antibacterial properties. By scrutinizing the nanostructures present on diamond surfaces, we embarked on an exploration of their potential deployment in nanoelectronics devices, biomedicine, and material processing. This research is primar ily geared towards enhancing the antibacterial attributes of diamonds, thereby catering to the stringent demands of biomedical applications. Our efforts are directed at mitigating infection risks, preserving the sterility of medical equipment, averting cro ss contamination, and ushering in the era of highly sensitive biosensors and diagnostic tools.Furthermore, we have delved into the realm of diamond thermoelectric properties. Despite diamonds' inherent high thermal conductivity, which historically posed c hallenges for their use in thermoelectric applications, we have endeavored to enhance their thermoelectric performance through innovative physical modification methodologies. Leveraging the unique material characteristics of diamonds, we have unlocked thei r potential for extended longevity and stability in comparison to other thermoelectric materials. This achievement translates into reduced maintenance requirements, lower replacement frequencies, and ultimately, cost savings. Moreover, diamonds' steadfast stability equips them to maintain peak performance even in the harshest of environments, such as aerospace and energy conversion systems. In summation, this doctoral thesis undertakes a comprehensive exploration of diamonds' attributes, encompassing growth methodologies, marine antibacterial applications, and thermoelectric properties. Our research not only augments the scientific understanding of diamonds but also fosters innovation and paves the way for their diverse applications across several sectors.

description: Hungarian agriculture has gone thru a long and difficult development since the First World War. The semi-feudal agriculture of the Horthy era between the two World Wars was followed by a land distribution after the Second World War, which created an agricultural system dominated by smallholders. However, the small farms were soon collectivized. Despite the forced collectivization, the large farms developed well and the living standard of the peasantry grew significantly. After the collapse of socialism in Hungary in 1990, political parties decided again to restructure agriculture. A new land distribution was carried out which created an agricultural system based on smallholdings. On the mostly too small, scattered holdings, the technical and technological levels, and the productivity are low. A small number of larger farms produces most of the marketed products. The only out way of this situation is farm-concentration and the cooperation of smallholders.

description: Few-shot learning aims at rapidly adapting to novel categories with only a handful of samples at test time, which has been predominantly tackled with the idea of meta-learning. However, meta-learning approaches essentially learn across a variety of few-shot tasks and thus still require large-scale training data with fine-grained supervision to derive a generalized model, thereby involving prohibitive annotation cost. In this paper, we advance the few-shot classification paradigm towards a more challenging scenario, i.e., cross-granularity few-shot classification, where the model observes only coarse labels during training while is expected to perform fine-grained classification during testing. This task largely relieves the annotation cost since fine-grained labeling usually requires strong domain-specific expertise. To bridge the cross-granularity gap, we approximate the fine-grained data distribution by greedy clustering of each coarse-class into pseudo-fine-classes according to the similarity of image embeddings. We then propose a meta-embedder that jointly optimizes the visual- and semantic-discrimination, in both instance-wise and coarse class-wise, to obtain a good feature space for this coarse-to-fine pseudo-labeling process. Extensive experiments and ablation studies are conducted to demonstrate the effectiveness and robustness of our approach on three representative datasets.

description: We present a detailed comparative systematic study using a sample of 221 Narrow-line Seyfert 1 (NLSy1) galaxies in comparison to a redshift matched sample of 154 Broad-line Seyfert 1 (BLSy1) galaxies based on their observations using ROSAT and/or XMM-Newton telescopes in soft X-ray band (0.1-2.0 keV). A homogeneous analysis is carried out to estimate their soft X-ray photon indices ($Γ^{s}_{X}$) and its correlations with other parameters of nuclear activities such as Eddington ratios (R$_\mathrm{Edd}$), bolometric luminosities (L$_\mathrm{bol}$), black hole masses (M$_\mathrm{BH}$) and the widths of the broad component of H$β$ lines (FWHM(H$β$)). In our analysis, we found clear evidence of the difference in the $Γ^{s}_{X}$ and R$_\mathrm{Edd}$ distributions among NLSy1 and BLSy1 galaxies, with steeper $Γ^{s}_{X}$ and higher R$_\mathrm{Edd}$ for the former. Such a difference also exists in the spectral indices distribution in hard X-ray ($Γ^{h}_{X}$), based on the analysis of 53 NLSy1 and 46 BLSy1 galaxies in the 2-10 keV energy band. The difference in R$_\mathrm{Edd}$ distributions does exist even after applying the average correction for the difference in the inclination angle of NLSy1 and BLSy1 galaxies. We also estimated R$_\mathrm{Edd}$, based on SED fitting of 34 NLSy1 and 30 BLSy1 galaxies over the 0.3-10 keV energy band and found that results are still consistent with R$_\mathrm{Edd}$ estimates based on the optical bolometric luminosity. Our analysis suggests that the higher R$_\mathrm{Edd}$ in NLSy1 is responsible for its steeper X-ray spectral slope compared to the BLSy1, consistent with the disc-corona model as proposed for the luminous AGNs.

description: Abstract: Cases of a novel coronavirus were first reported in Wuhan, Hubei province, China, in December 2019 and have since spread across the world. Epidemiological studies have indicated human-to-human transmission in China and elsewhere. To aid the analysis and tracking of the COVID-19 epidemic we collected and curated individual-level data from national, provincial, and municipal health reports, as well as additional information from online reports. All data are geo-coded and, where available, include symptoms, key dates (date of onset, admission, and confirmation), and travel history. The generation of detailed, real-time, and robust data for emerging disease outbreaks is important and can help to generate robust evidence that will support and inform public health decision making.

description: Ethanol mandates have led to an increase in the production of distillers dried grains (DDGs), a co-product of ethanol production that is incorporated into livestock rations. As with most competitive industries, there is some level of price risk in handling DDGs, and there is no DDG futures contract available for managing price risk. Commonly, DDGs are hedged using only corn futures. Our results suggest that cross-hedge risk may be reduced by including soybean meal futures in an encompassing cross-hedge strategy. Further, we also conclude soybean meal futures currently may be slightly more effective at reducing risk than in the past.

Magnetic susceptibility of diluted magnetic semiconductors
Creators: name: Kassaian, Adel
Publisher: name: University of British Columbia
Year: 2009

description: In this thesis we investigate the magnetic properties of (III,Mn)V diluted magnetic semiconductors in the low carrier concentration regime. Variational and perturbative methods are applied to an impurity-band model, in order to derive approximation schemes for computation of the dynamical and the static magnetic susceptibilities. Based on these, we carry out numerical simulations which allow us to investigate the effects of positional disorder of the Mn atoms on the magnetic properties of the system. The magnetic susceptibilities are shown to depend sensitively on the amount of positional disorder. The results we obtain are consistent with previous studies of the spin wave spectrum and of the inhomogeneous ferromagnetic state of these materials.

description: The 3D volumetric shape of the heart's left ventricle (LV) myocardium (MYO) wall provides important information for diagnosis of cardiac disease and invasive procedure navigation. Many cardiac image segmentation methods have relied on detection of region-of-interest as a pre-requisite for shape segmentation and modeling. With segmentation results, a 3D surface mesh and a corresponding point cloud of the segmented cardiac volume can be reconstructed for further analyses. Although state-of-the-art methods (e.g., U-Net) have achieved decent performance on cardiac image segmentation in terms of accuracy, these segmentation results can still suffer from imaging artifacts and noise, which will lead to inaccurate shape modeling results. In this paper, we propose a PC-U net that jointly reconstructs the point cloud of the LV MYO wall directly from volumes of 2D CT slices and generates its segmentation masks from the predicted 3D point cloud. Extensive experimental results show that by incorporating a shape prior from the point cloud, the segmentation masks are more accurate than the state-of-the-art U-Net results in terms of Dice's coefficient and Hausdorff distance.The proposed joint learning framework of our PC-U net is beneficial for automatic cardiac image analysis tasks because it can obtain simultaneously the 3D shape and segmentation of the LV MYO walls.

description: SARS-CoV-2 infection in children typically results in asymptomatic or mild disease. There is a paucity of studies on SARS-CoV-2 antiviral immunity in African children. We investigated SARS-CoV-2-specific T cell responses in 71 unvaccinated asymptomatic South African children who were seropositive or seronegative for SARS-CoV-2. SARS-CoV-2-specific CD4+ T cell responses were detectable in 83% of seropositive and 60% of seronegative children. Although the magnitude of the CD4+ T cell response did not differ significantly between the two groups, their functional profiles were distinct, with SARS-CoV-2 seropositive children exhibiting a higher proportion of polyfunctional T cells compared to their seronegative counterparts. The frequency of SARS-CoV-2-specific CD4+ T cells in seronegative children was associated with the endemic human coronavirus (HCoV) HKU1 IgG response. Overall, the presence of SARS-CoV-2-responding T cells in seronegative children may result from cross-reactivity to endemic coronaviruses and could contribute to the relative protection from disease observed in SARS-CoV-2-infected children.

description: Rising prices and uncertain supplies of petroleum, together with environmental concerns regarding fossil fuel combustion, have enhanced interest in biobased products and fuels. This study analyzes the feasibility of a multi-product biorefinery that uses wheat straw as feedstock to produce ethanol, electricity, and cellulose nanofibers. Nanofibers (nanowhiskers) would be used as reinforcements in a biobased nanocomposite material that could substitute for fiberglass in many applications. The growth of a biobased industry could have major economic development implications for the Great Plains/Midwest region.
Survey of 360$^{\circ}$ domain walls in magnetic heterostructures: topology, chirality and current-driven dynamics
Creators: name: Li, Mei

Subjects: subject: Mesoscale and Nanoscale Physics (cond-mat.mes-hall)

description: Chirality and current-driven dynamics of topologically nontrivial 360$^{\circ}$ domain walls (360DWs) in magnetic heterostructures (MHs) are systematically investigated. For MHs with normal substrates, the static 360DWs are Néel-type with no chirality. While for those with heavy-metal substrates, the interfacial Dzyaloshinskii-Moriya interaction (iDMI) therein makes 360DWs prefer specific chirality. Under in-plane driving charge currents, as the direct result of "full-circle" topology a certain 360DW does not undergo the "Walker breakdown"-type process like a well-studied 180$^{\circ}$ domain wall as the current density increases. Alternatively, it keeps a fixed propagating mode (either steady-flow or precessional-flow, depending on the effective damping constant of the MH) until it collapses or changes to other types of solition when the current density becomes too high. Similarly, the field-like spin-orbit torque (SOT) has no effects on the dynamics of 360DWs, while the anti-damping SOT has. For both modes, modifications to the mobility of 360DWs by iDMI and anti-damping SOT are provided.

Geometric approaches to assessing the numerical feasibility for conducting matching-adjusted indirect comparisons

Year: 2021
Subjects: subject: Applications (stat.AP)

description: We discuss how to handle matching-adjusted indirect comparison (MAIC) from a data analyst's perspective. We introduce several multivariate data analysis methods to assess the appropriateness of MAIC for a given data set. These methods focus on comparing the baseline variables used in the matching from a study that provides the summary statistics, or aggregated data (AD) and a study that provides individual patient level data (IPD). The methods identify situations when no numerical solutions are possible with the MAIC method. This helps to avoid misleading results being produced. Moreover, it has been observed that sometimes contradicting results are reported by two sets of MAIC analyses produced by two teams, each having their own IPD and applying MAIC using the AD published by the other team. We show that an intrinsic property of the MAIC estimated weights can be a contributing factor for this phenomenon.
