A multiscale approach to liquid crystal nematics via statistical field theory
Creators: name: Lu, Bing-Sui
Publisher: name: arXiv
Year: 2017
Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)
subject: FOS: Physical sciences

description: We propose an approach to a multiscale problem in the theory of thermotropic uniaxial nematics based on the method of statistical field theory. This approach enables us to relate the coefficients $A$, $B$, $C$, $L_1$ and $L_2$ of the Landau-de Gennes free energy for the isotropic-nematic phase transition to the parameters of a molecular model of uniaxial nematics, which we take to be a lattice gas model of nematogenic molecules interacting via a short-ranged potential. We obtain general constraints on the temperature and volume fraction of nematogens for the Landau-de Gennes theory to be stable against molecular orientation fluctuations at quartic order. In particular, for the case of a fully occupied lattice, we compute the values of the isotropic-nematic transition temperature and the order parameter discontinuity predicted by (i) a continuum approximation of the nearest-neighbor Lebwohl-Lasher model and (ii) a Lebwohl-Lasher-type model with a nematogenic interaction of finite range. We find that the predictions of (i) are in reasonably good agreement with known results of MC simulation.

description: Social organizations, from microbes to insect colonies exhibit remarkable abilities in a self-organized division of labour. Previous models of social colonies have not fully incorporated important characteristics of a colony. In this thesis, two well-established learning mechanisms, namely social learning and individual learning, are utilized and compared to identify their role in the emergence of certain characteristics of interest.
In different chapters of this thesis, the emergence of inactive workers and task specialization of age groups under various environmental conditions and the effect of delays that may occur in the realisation of task feedback are studied using these learning paradigms.
Remarks on Kawamata's effective non-vanishing conjecture for manifolds with trivial first Chern classes
Creators: name: Cao, Yalong

Publisher: name: arXiv
Year: 2016

description: Kawamata proposed a conjecture predicting that every nef and big line bundle on a smooth projective variety with trivial first Chern class has nontrivial global sections. We verify this conjecture for several cases, including (i) all hyperkähler varieties of dimension $\leq 6$; (ii) all known hyperkähler varieties except for O'Grady's 10-dimensional example; (iii) general complete intersection Calabi-Yau varieties in certain Fano manifolds (e.g. toric ones). Moreover, we investigate the effectivity of Todd classes of hyperkähler varieties and Calabi-Yau varieties. We prove that the fourth Todd classes are "fakely effective" for all hyperkähler varieties and general complete intersection Calabi-Yau varieties in products of projective spaces.

description: During Human-Human and Human-Computer Interaction, the affective behaviour of persons in a group can change and impact other group members. Hence, from the perspective of Human-Computer Interaction, it is important to develop automatic methods for affective behaviour analysis for groups. However, the lack of datasets and computational representation of groups for diverse group settings still needs improvement. This research addresses these challenges by building a group modelling framework for different tasks and using the model for real-world applications. These research contributions have a wide range of applications in affective computing, human-computer interaction and social-signal processing.

Realizing Fulde-Ferrell Superfluids via a Dark-State Control of Feshbach Resonances

description: We propose that the long-sought Fulde-Ferrell superfluidity with nonzero momentum pairing can be realized in ultracold two-component Fermi gases of $^{40}$K or $^{6}$Li atoms by optically tuning their magnetic Feshbach resonances via the creation of a closed-channel dark state with a Doppler-shifted Stark effect. In this scheme, two counterpropagating optical fields are applied to couple two molecular states in the closed channel to an excited molecular state, leading to a significant violation of Galilean invariance in the dark-state regime and hence to the possibility of Fulde-Ferrell superfluidity. We develop a field theoretical formulation for both two-body and many-body problems and predict that the Fulde-Ferrell state has remarkable properties, such as anisotropic single-particle dispersion relation, suppressed superfluid density at zero temperature, anisotropic sound velocity and rotonic collective mode. The latter two features can be experimentally probed using Bragg spectroscopy, providing a smoking-gun proof of Fulde-Ferrell superfluidity.

description: The CORSIKA 8 project aims to develop a versatile and modern framework for particle shower simulations that meets the new needs of experiments and addresses the caveats of existing codes. Of particular relevance is the ability to compute particle showers that pass through two or more different media, of varying density, in a single run within a single code. CORSIKA 8 achieves this flexibility by using a volume tree that specifies volume containment, allowing one to quickly query to which medium a point belongs. Thanks to this design we are able to construct very specific environments with different geometries and media. As an example, we demonstrate this new functionality by running particle showers penetrating from air into Antarctic ice and validating them with a combination of the well-established CORSIKA 7 and GEANT4 codes.

description: We prove global existence of instantaneously complete Yamabe flows on hyperbolic space of arbitrary dimension $m\geq3$. The initial metric is assumed to be conformally hyperbolic with conformal factor and scalar curvature bounded from above. We do not require initial completeness or bounds on the Ricci curvature. If the initial data are rotationally symmetric, the solution is proven to be unique in the class of instantaneously complete, rotationally symmetric Yamabe flows.

description: We present Chandra observations of hot gas structures, characteristic of gas stripping during infall, in the Virgo cluster elliptical galaxy M60 (NGC4649) located $1$ Mpc east of M87. $0.5-2$ keV Chandra X-ray images show a sharp leading edge in the surface brightness $12.4 \pm 0.1$ kpc north and west of the galaxy center in the direction of M87 characteristic of a merger cold front due to M60's motion through the Virgo ICM. We measured a temperature of $1.00 \pm 0.02$ keV for abundance $0.5 Z_\odot$ inside the edge and $1.37^{+0.35}_{-0.19}$ keV for abundance $0.1 Z_\odot$ in the Virgo ICM free stream region. We find that the observed jump in surface brightness yields a density ratio of $6.44^{+1.04}_{-0.67}$ between gas inside the edge and in the cluster free stream region. If the edge is a cold front due solely to the infall of M60 in the direction of M87, we find a pressure ratio of $4.7^{+1.7}_{-1.4}$ and Mach number $1.7 \pm 0.3$. For 1.37 keV Virgo gas we find a total infall velocity for M60 of $1030 \pm 180$ kms$^{-1}$. We calculate the motion in the plane of the sky to be $1012^{+183}_{-192}$ km$^{-1}$ implying an inclination angle $ξ= 11 \pm 3$ degrees. Surface brightness profiles show the presence of a faint diffuse gaseous tail. We identify filamentary, gaseous wing structures caused by the galaxy's motion through the ICM. The structure and dimensions of these wings are consistent with simulations of Kelvin-Helmholtz instabilities as expected if the gas stripping is close to inviscid.

description: With the mobile industry’s development, the competition has become increasingly intense. Ensuring the high quality of apps to remain competitive has become a top priority for app markets and developers. However, this is not easy as app markets are constantly challenged by malware, and app developers are often under pressure to fix vulnerabilities and learn new knowledge. Just like big data that brings vast amounts of data enabling big data applications, large repositories of Android app programs allow a new class of applications that leverage “big code”. This thesis seeks to utilize big code analysis-based techniques to improve the quality of Android apps.

We propose a way of taking the flat limit of representations in (anti-) de Sitter spaces in terms of these characters, and conjecture the spectrum resulting from taking the flat limit of mixed-symmetry fields in de Sitter spacetime. We comment on a possible equivalent of the scalar singleton for the de Sitter (dS) spacetime.

description: Deepfake has recently raised a plethora of societal concerns over its possible security threats and dissemination of fake information. Much research on deepfake detection has been undertaken. However, detecting low quality as well as simultaneously detecting different qualities of deepfakes still remains a grave challenge. Most SOTA approaches are limited by using a single specific model for detecting certain deepfake video quality type. When constructing multiple models with prior information about video quality, this kind of strategy incurs significant computational cost, as well as model and training data overhead. Further, it cannot be scalable and practical to deploy in real-world settings. In this work, we propose a universal intra-model collaborative learning framework to enable the effective and simultaneous detection of different quality of deepfakes. That is, our approach is the quality-agnostic deepfake detection method, dubbed QAD . In particular, by observing the upper bound of general error expectation, we maximize the dependency between intermediate representations of images from different quality levels via Hilbert-Schmidt Independence Criterion. In addition, an Adversarial Weight Perturbation module is carefully devised to enable the model to be more robust against image corruption while boosting the overall model's performance. Extensive experiments over seven popular deepfake datasets demonstrate the superiority of our QAD model over prior SOTA benchmarks.

3D magnetization currents, magnetization loop, and saturation field in superconducting rectangular prisms

Year: 2017
Subjects: subject: Superconductivity (cond-mat.supr-con)

description: Bulk superconductors are used in both many applications and material characterization experiments, being the bulk shape of rectangular prism very frequent. However the magnetization currents are still mostly unknown for this kind of three dimensional (3D) shape, specially below the saturation magnetic field. Knowledge of the magnetization currents in this kind of samples is needed to interpret the measurements and the development of bulk materials for applications. This article presents a systematic analysis of the magnetization currents in prisms of square base and several thicknesses. We make this study by numerical modeling using a variational principle that enables high number of degrees of freedom. We also compute the magnetization loops and the saturation magnetic field, using a definition that is more relevant for thin prisms than previous ones. The article presents a practical analytical fit for any aspect ratio. For applied fields below the saturation field, the current paths are not rectangular, presenting 3D bending. The thickness-average results are consistent with previous modeling and measurements for thin films. The 3D bending of the current lines indicates that there could be flux cutting effects in rectangular prisms. The component of the critical current density in the applied field direction may play a role, being the magnetization currents in a bulk and a stack of tapes not identical.

description: Correlated electron systems on a honeycomb lattice have emerged as a fertile playground to explore exotic electronic phenomena. Theoretical and experimental work has appeared to realize novel behavior, including quantum Hall effects and valleytronics, mainly focusing on van der Waals compounds, such as graphene, chalcogenides, and halides. In this article, we review our theoretical study on perovskite transition-metal oxides (TMOs) as an alternative system to realize such exotic phenomena. We demonstrate that novel quantum Hall effects and related phenomena associated with the honeycomb structure could be artificially designed by such TMOs by growing their heterostructures along the [111] crystallographic axis. One of the important predictions is that such TMO heterostructures could support two-dimensional topological insulating states. The strong correlation effects inherent to TM $d$ electrons further enrich the behavior.

description: eHealth app users are naturally diverse in terms of their human aspects, e.g., their emotional reactions to the app, varying language proficiency, socioeconomic status, educational level, cognitive style, personality, and many more. Unfortunately, many eHealth apps do not take these user differences sufficiently into account, making them ineffective or even unusable. Recognizing this gap, Md Shamsujjoha proposed a more integrated approach that better addresses human aspects of eHealth apps in his Ph.D. He identified the range and nature of key human aspects and proposed improved actionable guidelines, development workflow, and best practice examples to better support diverse users in practice.
title: Investigating pollen compatibility of commercial sweet cherry cultivars by DNA analysis
Creators: name: Lomax, JMH
Publisher: name: University of Tasmania
Year: 2021

description: Sweet cherries (Prunus avium L.) are largely self-incompatible, which is determined by a gametophytic self-incompatibility system that is controlled by a multi-allelic S-locus. Commercial cherry orchards select cross-compatible cultivars based on synchronous flowering and cross-compatible S-alleles to maximise pollination success. My project evaluated molecular approaches to: 1) determine the unknown S-allele profile in three sweet cherry cultivars (Simone, Sweet Georgia and Reid Fruits in-house cultivar; SLK) by DNA sequencing and 2) identify the pollinisers of Kordia and Regina that are notorious for below average fruit set (<20%) using S-locus genes and microsatellite markers (SSRs). These molecular techniques have been tested in other plant models, however, there are limited examples in commercial sweet cherry orchards. DNA sequencing unequivocally identified that the previously unknown S-alleles of Simone and Sweet Georgia are S1 and S4’. Interestingly, this is consistent with industry reports that both Simone and Sweet Georgia are self-compatible. SLK, had S1 and S3 alleles, supporting suggestions that it could be a mutation of the Regina cultivar. This new information means that producers can utilise these cultivars with confidence in their genetic compatibility. Primers targeting specific alleles of the SFB gene (S\(_1\), S\(_3\), S\(_4\), S\(_4\)’, S\(_6\), S\(_9\), S\(_{12}\), S\(_{13}\) and S\(_{36}\)), revealed the pollen donor candidates for Kordia and Regina seeds in the open-pollinated orchard, but failed to discriminate among candidates that shared S-alleles. Five out of thirteen microsatellites were identified to amplify small size differences between candidate pollen donors but require accurate sizing using a DNA sequencer to be practical as agarose gel electrophoresis did not provide reliable discrimination. This was beyond the resources available for this project. The primers we designed can be developed into a multiplex PCR to make this technique even faster and cheaper. Orchardists can use these methods, which are also applicable to other Prunus crops, to optimise their orchard design and assist in the selection and introduction of new cultivars.

description: Data collected by Earth observation satellites are important information sources about the environment and state of our planet. Deep learning techniques provide ways to use this data to model environmental indicators, thus are useful in systems that alert us to potential environmental disasters. This thesis advances deep learning techniques to monitor the moisture content of vegetation, which is important for wildfire risk monitoring, by designing models that make accurate, timely, and extensive predictions. These models can potentially assist wildfire management authorities to develop plans mitigating the effects of catastrophic wildfires, thus helping to protect our environment and save human lives.

description: We define and study the quantum equivariant $K$-theory of cotangent bundles over Grassmannians. For every tautological bundle in the $K$-theory we define its one-parametric deformation, referred to as quantum tautological bundle. We prove that the spectrum of operators of quantum multiplication by these quantum classes is governed by the Bethe ansatz equations for the inhomogeneous $XXZ$ spin chain. In addition, we prove that each such operator corresponds to the universal elements of quantum group $\mathcal{U}_{\hbar}(\widehat{\mathfrak{sl}}_2)$. In particular, we identify the Baxter operator for the $XXZ$ spin chain with the operator of quantum multiplication by the exterior algebra tautological bundle. The explicit universal combinatorial formula for this operator is found. The relation between quantum line bundles and quantum dynamical Weyl group is shown.

description: Payment channels help make blockchains more scalable, but creating them for scriptless blockchains like Monero is challenging. This study introduces AuxChannel, the first bi-directional payment channel protocol for scriptless blockchains without a limited lifetime. It only requires the support of verifiably encrypted signatures, known as adaptor signatures. We adapt AuxChannel to Monero, calling it MoChannel. We also propose MoNet, a multi-hop payment framework ensuring anonymity and fungibility for Monero. To resolve channel disputes, a distributed third party called FPSS is suggested. They introduce versatile building blocks like CVES, VCOF, GCAS, and FPSS to efficiently construct payment channels and multi-hop payments on scriptless blockchains.

However, existing PLM-probing studies focus mainly on factual knowledge, lacking a systematic probing of ontological knowledge. In this paper, we focus on probing whether PLMs store ontological knowledge and have a semantic understanding of the knowledge rather than rote memorization of the surface form. To probe whether PLMs know ontological knowledge, we investigate how well PLMs memorize: (1) types of entities; (2) hierarchical relationships among classes and properties, e.g., Person is a subclass of Animal and Member of Sports Team is a subproperty of Member of ; (3) domain and range constraints of properties, e.g., the subject of Member of Sports Team should be a Person and the object should be a Sports Team. To further probe whether PLMs truly understand ontological knowledge beyond memorization, we comprehensively study whether they can reliably perform logical reasoning with given knowledge according to ontological entailment rules. Our probing results show that PLMs can memorize certain ontological knowledge and utilize implicit knowledge in reasoning. However, both the memorizing and reasoning performances are less than perfect, indicating incomplete knowledge and understanding.

description: We consider the most general action for gravity which is quadratic in curvature. In this case first order and second order formalisms are not equivalent. This framework is a good candidate for a unitary and renormalizable theory of the gravitational field; in particular, there are no propagators falling down faster than $\tfrac{1}{p^2}$. Calculations are somewhat involved when all monomials are considered, but we have intended to laid down the general case. The interaction between external sources is analyzed; this interaction is conveyed mainly by the three-index connection field. The theory as it stands, is in the conformal invariant phase; only when Weyl invariance is broken through the coupling to matter can an Einstein-Hilbert term (and its corresponding Planck mass scale) be generated by quantum corrections.

description: Bitcoin can only process around 7 transactions per second on average which is much lower than the figures for centralised payment systems such as Visa. Payment channel is an effective approach to improve the scalability of blockchain-based cryptocurrencies. However, none of the current payment channel schemes achieve all the required properties. This thesis formally defines the required properties of a payment channel, examines the existing schemes with respect to the defined properties and finally proposes new schemes that outperform the current ones.
Dynamic Transitions and Baroclinic Instability for 3D Continuously Stratified Boussinesq Flows

description: The main objective of this article is to study the nonlinear stability and dynamic transitions of the basic (zonal) shear flows for the three-dimensional continuously stratified rotating Boussinesq model. The model equations are fundamental equations in geophysical fluid dynamics, and dynamics associated with their basic zonal shear flows play a crucial role in understanding many important geophysical fluid dynamical processes, such as the meridional overturning oceanic circulation and the geophysical baroclinic instability. In this paper, first we derive a threshold for the energy stability of the basic shear flow, and obtain a criteria for nonlinear stability in terms of the critical horizontal wavenumbers and the system parameters such as the Froude number, the Rossby number, the Prandtl number and the strength of the shear flow. Next we demonstrate that the system always undergoes a dynamic transition from the basic shear flow to either a spatiotemporal oscillatory pattern or circle of steady states, as the shear strength $Λ$ of the basic flow crosses a critical threshold $Λ_c$. Also we show that the dynamic transition can be either continuous or catastrophic, and is dictated by the sign of a transition parameter $A$, fully characterizing the nonlinear interactions of different modes. A systematic numerical method is carried out to explore transition in different flow parameter regimes. We find that the system admits only critical eigenmodes with horizontal wave indices $(0,m_y)$. Such modes, horizontally have the pattern consisting of $m_y$-rolls aligned with the x-axis. Furthermore, numerically we encountered continuous transitions to multiple steady states, continuous and catastrophic transitions to spatiotemporal oscillations.

description: We point out that a spontaneous scalarized inspiring double neutron star (DNS) system can provide us a natural laboratory to investigate the generation mechanism of masses for gravitons. Because of the appearance of a gravitational scalar background field, with small fluctuations, converged by iterative interplay of the mass dimensional external scalar fields, the binary system suffers from a spontaneous Lorentz symmetry breaking. The two scalarized NSs dip in a Higgs-like gravitational scalar potential, where the massless scalar background fluctuation field plays the role of Higgs field. Consequently, the gravitational scalar background field becomes massive. The radiated gravitons, propagating in a Yukawa-corrected potential, acquire a scalar-background-dependent mass term, in a massive-scalar-field-mediated way. We demonstrate that the mass of gravitons depends on intrinsic properties of the sources, which is not a certain value. The background-dependent masses for gravitons from scalarized orbital shrinking DNS is variable with the compactness of two components, as well as the separation of the binary. We get the effective masses for gravitons radiated from 8 detected DNS binaries with more precise mass measurements in our galaxy, whose values appear to be of the order of $10^{-23} ev/c^2$. It is found that more massive gravitons radiate from more closer DNS system, consisting with the higher-frequency gravitational waves from closer binaries.

description: Unnecessary diagnostic tests place an increasing burden on the healthcare system and can cause harm to patients. The project investigated how diagnostic test-ordering decision-making in a public hospital emergency department setting could be supported based on a deeper understanding of this process. It proposes a detailed dual-process-based decision-making model for diagnostic test ordering and explores general design principles that can inform the design of a nudge-based clinical decision support intervention to assist with better diagnostic test ordering.
A dual form of the sharp Nash inequality and its weighted generalization

description: The well known duality between the Sobolev inequality and the Hardy-Littlewood-Sobolev inequality suggests that the Nash inequality could also have an interesting dual form, even though the Nash inequality relates three norms instead of two. We provide such a dual form here with sharp constants. This dual inequality relates the $L^2$ norm to the infimal convolution of the $L^\infty $ and $H^{-1}$ norms. The computation of this infimal convolution is a minimization problem, which we solve explicitly, thus providing a new proof of the sharp Nash inequality itself. This proof, via duality, also yields the sharp form of some new, weighted generalizations of the Nash inequality as well as the dual of these weighted variants.

description: We obtain Morita invariant versions of Eilenberg-Watts type theorems, relating Deligne products of finite linear categories to categories of left exact as well as of right exact functors. This makes it possible to switch between different functor categories as well as Deligne products, which is often very convenient. For instance, we can show that applying the equivalence from left exact to right exact functors to the identity functor, regarded as a left exact functor, gives a Nakayama functor. The equivalences of categories we exhibit are compatible with the structure of module categories over finite tensor categories. This leads to a generalization of Radford's $S^4$-theorem to bimodule categories. We also explain the relation of our construction to relative Serre functors on module categories that are constructed via inner Hom functors.
