description: The JavaScript language is a core component of active and dynamic web content in the Internet today. Besides its great success in enhancing web applications, however, JavaScript provides the basis for drive-by downloads—attacks exploiting vulnerabilities in web browsers and their extensions for unnoticeably downloading malicious so ware. Due to the diversity and frequent use of obfuscation in these JavaScript attacks, static code inspection proves ineffective in practice. While dynamic analysis and honeypots provide means to identify drive-by-download attacks, current approaches induce a significant overhead which renders immediate prevention of attacks intractable. In this paper, we present Cujo, a system for automatic detection and prevention of drive-by-download attacks. Embedded in a web proxy, Cujo transparently inspects web pages and blocks delivery of malicious JavaScript code. Static and dynamic code features are extracted on-the-fly and analysed for malicious patterns using efficient techniques of machine learning. We demonstrate the efficacy of Cujo in different experiments, where it detects 95% of the drive-by downloads with few false alarms and a median run-time of 500 ms per web page—a quality that, to the best of our knowledge, has not been attained in previous work on detection of drive-by-download attacks.

description: Most antineutrinos produced in a nuclear reactor have energies below the inverse beta decay threshold, and have not yet been detected. We show that a coherent elastic neutrino-nucleus scattering experiment with an ultra-low energy threshold like NUCLEUS can measure the flux of reactor neutrinos below 1.8 MeV. Using a regularized unfolding procedure, we find that a meaningful upper bound can be placed on the low energy flux, but the existence of the neutron capture component cannot be established.

description: Metamodels define a foundation for describing software system interfaces which can be used during software or data integration processes. The report is part of the BIZYCLE project, which examines applicability of model-based methods, technologies and tools to the large-scale industrial software and data integration scenarios. The developed metamodels are thus part of the overall BIZYCLE process, comprising of semantic, structural, communication, behavior and property analysis, aiming at facilitating and improving standard integration practice. Therefore, the project framework will be briefly introduced first, followed by the detailed metamodel and transformation description as well as motivation/illustration scenarios.

description: An analysis of today's situation at Credit Suisse has shown severe problems, because it is based on current best practices and ad-hoc modelling techniques to handle important aspects of security, risk and compliance. Based on this analysis we propose in this paper a new enterprise model which allows the construction, integration, transformation and evaluation of different organizational models in a big decentralized organization like Credit Suisse. The main idea of the new model framework is to provide small decentralized models and intra-model evaluation techniques to handle services, processes and rules separately for the business and IT universe on one hand and for human-centric and machine-centric concepts on the other hand. Furthermore, the new framework provides inter-modelling techniques based on algebraic graph transformation to establish the connection between different kinds of models and to allow integration of the decentralized models. In order to check for security, risk and compliance in a suitable way, our models and techniques are based on different kinds of formal methods. In this paper, we show that algebraic graph transformation techniques are useful not only for intra-modelling - using graph grammars for visual languages and graph constraints for requirements - but also for inter-modelling - using triple graph grammars for model transformation and integration. Altogether, we present the overall idea of our new model framework and show how to solve specific problems concerning intra- and inter-modelling as first steps. This should give evidence that our framework can also handle important other requirements for enterprise modelling in a big decentralized organization like Credit Suisse.

description: A shift from even-aged forest management to uneven-aged management practices leads to a problem rather different from the existing straightforward practice that follows a rotation cycle of artificial regeneration, thinning of inferior trees and a clearcut. A lack of realistic models and methods suggesting how to manage uneven-aged stands in a way that is economically viable and ecologically sustainable creates difficulties in adopting this new management practice. To tackle this problem, we make a two-fold contribution in this paper. The first contribution is the proposal of an algorithm that is able to handle a realistic uneven-aged stand management model that is otherwise computationally tedious and intractable. The model considered in this paper is an empirically estimated size-structured ecological model for uneven-aged spruce forests. The second contribution is on the sensitivity analysis of the forest model with respect to a number of important parameters. The analysis provides us an insight into the behavior of the uneven-aged forest model.

description: In this work, we give two proposals regarding the status of connectivity of entanglement wedges and the associated saturation of mutual information. The first proposal has been given for the scenario before the Page time depicting the fact that at a particular value of the observer's time $t_b=t_R$ (where $t_R\llβ$), the mutual information $I(R_+:R_-)$ vanishes representing the disconnected phase of the radiation entanglement wedge. We argue that this time is the Hartman-Maldacena time at which the fine-grained entropy of radiation goes as $S(R)\sim \log(β)$, where $β$ is the inverse of Hawking temperature of the black hole. On the other hand, the second proposal probes the crucial role played by the mutual information of black hole subsystems in obtaining the correct Page curve of radiation.

description: Hepatitis E virus (HEV) is the leading cause of acute viral hepatitis. Numerous studies have investigated the dynamics of HEV infection markers, but the most suitable marker for diagnosing ongoing or recent HEV infection remains to be determined. Recent evidence suggests that serum antigen testing is superior to serum IgM and RNA quantification. Moreover, it has been found that infected individuals excrete HEV antigen in significant quantities through urine. To address this question, we conducted a longitudinal analysis involving 16 patients with acute or chronic HEV infection in an area where genotype 3 HEV is prevalent. Our findings indicate that the diagnostic and monitoring capabilities of antigen testing for HEV infection can be further enhanced by measuring it in urine. Additionally, we were able to demonstrate that this enhancement is likely due to the presence of HEV-reactive IgG in blood plasma, which hampers efficient detection of HEV antigen through sandwich ELISA. In conclusion, urine-based antigen testing appears to be superior to measuring anti-HEV antibodies or viral RNA for diagnosing suspected HEV infection and monitoring ongoing infections

description: In the Gaia era it is increasingly apparent that traditional static, parameterized models are insufficient to describe the mass distribution of our complex, dynamically evolving Milky Way (MW). In this work, we compare different time-evolving and time-independent representations of the gravitational potentials of simulated MW-mass galaxies from the FIRE-2 suite of cosmological baryonic simulations. Using these potentials, we calculate actions for star particles in tidal streams around three galaxies with varying merger histories at each snapshot from 7 Gyr ago to the present day. We determine the action-space coherence preserved by each model using the Kullback-Leibler Divergence to gauge the degree of clustering in actions and the relative stability of the clusters over time. We find that all models produce a clustered action space for simulations with no significant mergers. However, a massive (mass ratio prior to infall more similar than 1:8) interacting galaxy not present in the model will result in mischaracterized orbits for stars most affected by the interaction. The locations of the action space clusters (i.e. the orbits of the stream stars) are only preserved by the time-evolving model, while the time-independent models can lose significant amounts of information as soon as 0.5--1 Gyr ago, even if the system does not undergo a significant merger. Our results imply that reverse-integration of stream orbits in the MW using a fixed potential is likely to give incorrect results if integrated longer than 0.5 Gyr into the past.

description: We consider the downlink of a two-layer heterogeneous network, comprising macro cells (MCs) and small cells (SCs). The existing literature generally assumes independent placements of the access points (APs) in different layers; in contrast, we analyze a dependent placement where SC APs are placed at locations with poor service from the MC layer. Our goal is to obtain an estimate of the number of SCs required to maintain a target outage rate. Such an analysis is trivial if the MCs are located according to a Poisson point process (PPP), which provides a lower bound on performance. Here, we consider MCs placed on a hexagonal grid, which complements the PPP model by providing an upper bound on performance. We first provide accurate bounds for the average interference within a MC when SCs are not used. Then, by obtaining the outage areas, we estimate the number of SCs required within an MC to overcome outage. If resource allocation amongst SCs is not used, we show that the problem of outage is not solved completely, and the residual outage area depends on whether co-channel or orthogonal SCs are used. Simulations show that a much smaller residual outage area is obtained with orthogonal SCs.

description: Critical business processes can fail. A Business Continuity Management System is a special management system that will define how to recover from such failures and specifies temporary work-arounds to make sure a company is not going out of business in the worst case. However, because today's implementations are primarily organizational best-practice solutions, their security, risk and compliance issues in such a recovery situation are mostly unknown. Algebraic graph theory can be used as a formal method supporting employees when running business processes need to be reconfigured to recover from specific failures. The example discussed is a loan granting process in a real-world banking environment. Because such a process has to respect certain laws, regulations and rules even in emergency situations, we sketch how this can be done during the process reconfiguration by looking at security, risk and compliance issues, compatible with the graph technique. Furthermore, we show how the analysis can be extended to requirements concerning the information ow using the process algebra mCRL2.
Narcissism and self-enhancement: Self-presentation, affect, and the moderating role of contingencies of self-worth
Creators: name: Collins, David Russell
Publisher: name: La Trobe
Year: 2023

description: Abstract: Narcissists typically present themselves in self-enhancing ways to gain validation (through positive social appraisals) of grandiose, yet uncertain self-views. Using e-mail, Studies 1 and 2 investigated several intra- and interpersonal variables that may influence narcissists' self-presentational behaviour. University students rated themselves on self domains requiring either external validation (e.g., attractiveness) or internal validation (e.g., morality), after being randomly assigned to be either accountable or non-accountable to an evaluative audience for their self-ratings (Study 1), to present their self-ratings to either a single or multiple person evaluative audience (Study 2), and to expect to present their self-ratings to either a high or low status evaluative audience (Studies 1 and 2).Results suggested that when degree of external self-worth contingency (Crocker & Wolfe, 2001) was high, narcissists were insensitive to strategic self-presentational requirements, presenting themselves in a typically self-enhancing manner on external domains when accountable and when presenting to a multiple person audience. Non-narcissists showed more contextual sensitivity when degree of external self-worth contingency was high, and were more modest when these social contextual variables were present. Participants in Study 3 were given bogus positive or negative personality feedback on either their moral virtue or competitive spirit.Narcissists reported greater anger after receiving negative feedback, while also responding to negative feedback with inflated self-presentations. A key finding was that the combination of a high degree of self-worth contingency and negative feedback resulted in increases in self-reported depression and drops in state self-esteem in narcissists. Results suggest that narcissists are chronically vigilant for self-enhancement opportunities, but may be insensitive to social constraints and norms in their efforts to construct their grandiose identities. Narcissists are especially vigilant for self-enhancement opportunities on contingent domains, yet when negative feedback is received in these domains where self-worth is staked, depression and lowered self-esteem may result.

Pacos: Modeling Users' Interpretable and Context-Dependent Choices in Preference Reversals

description: Choice problems refer to selecting the best choices from several items, and learning users' preferences in choice problems is of great significance in understanding the decision making mechanisms and providing personalized services. Existing works typically assume that people evaluate items independently. In practice, however, users' preferences depend on the market in which items are placed, which is known as context effects; and the order of users' preferences for two items may even be reversed, which is referred to preference reversals. In this work, we identify three factors contributing to context effects: users' adaptive weights, the inter-item comparison, and display positions. We propose a context-dependent preference model named Pacos as a unified framework for addressing three factors simultaneously, and consider two design methods including an additive method with high interpretability and an ANN-based method with high accuracy. We study the conditions for preference reversals to occur and provide an theoretical proof of the effectiveness of Pacos in addressing preference reversals. Experimental results show that the proposed method has better performance than prior works in predicting users' choices, and has great interpretability to help understand the cause of preference reversals.

Weak Cosmic Censorship Conjecture in Myers-Perry Black Hole with Separability

description: We investigate the weak cosmic censorship conjecture in Myers-Perry black holes with arbitrary rotations in general dimensions based on the scattering of a massless scalar field. From the fluxes of the scalar field flowing into the black hole, the changes in mass and angular momenta of the black hole are obtained. However, the extremal and near-extremal black holes with the aforementioned changes are still black holes in the final state. Hence, the conjecture is valid for our investigation. Furthermore, we analyze the changes in the black hole from a thermodynamic perspective to highlight that the laws of thermodynamics support the conjecture.

Aphasia and topic talk: a case study
Creators: name: Barnes, Scott Edward
Publisher: name: Macquarie University
Year: 2022
Subjects: Other education not elsewhere classified

description: This study uses Conversation Analysis (CA) to examine the organisation of topic talk in interactions involving a person with aphasia (Valerie). Approximately three and a half hours of video recordings involving Valerie were collected and analysed for this study. The most outstanding aggregate feature of Valerie's topic talk was an asymmetry of speakership. It was found that Valerie's routine conversation partners spoke more, and for longer periods. This study identifies the motivations for this asymmetry, and the mechanisms of its accomplishment. In doing so, it also analyses how Valerie used particular linguistic forms to implement discrete actions during topic talk. Valerie's conduct as both a primary speaker and a recipient during topic talk is described. Initiating and progressing topic talk were found to be recurrently difficult for her. Valerie had more success with topic talk initiations that projected primary speakership for her conversation partners. These topic talk initiations frequently involved turn-initial and. It is argued that and-prefaced turns offered Valerie a number of interactional advantages in general, and for initiating topic talk in particular. Valerie's activities as a recipient during topic talk are then discussed. One highly recurrent response - that's right - was selected for analysis, and the following functional variants were identified: confirming; mutual stance; recognition; compliment; and restored intersubjectivity. Composite responses involving that's right are also examined. This study contributes to conversation-analytic research by describing largely unexamined ways of using and and that's right during everyday talk-in-interaction. It contributes to aphasiology by offering new information about the effects of aphasia on the organisation of topic talk, and by helping expand the communicative activities and linguistic resources that are considered relevant for investigating and treating aphasia.

description: Simulated training platforms offer a suitable avenue for surgical students and professionals to build and improve upon their skills, without the hassle of traditional training methods. To enhance the degree of realistic interaction paradigms of training simulators, great work has been done to both model simulated anatomy in more realistic fashion, as well as providing appropriate haptic feedback to the trainee. As such, this chapter seeks to discuss the ongoing research being conducted on haptic feedback-incorporated simulators specifically for Endoscopic Sinus Surgery (ESS). This chapter offers a brief comparative analysis of some EES simulators, in addition to a deeper quantitative and qualitative look into our approach to designing and prototyping a complete virtual-based haptic EES training platform.

description: We explore the dependence of fermion propagators on the covariant gauge fixing parameter in quantum electrodynamics (QED) with the number of spacetime dimensions kept explicit. Gauge covariance is controlled by the the Landau-Khalatnikov-Fradkin transformation (LKFT). Utilizing its group nature, the LKFT for a fermion propagator in Minkowski space is solved exactly. The special scenario of 3D is used to test claims made for general cases. When renormalized correctly, a simplification of the LKFT in 4D has been achieved with the help of fractional calculus.

description: Current hardware for quantum computing suffers from high levels of noise, and so to achieve practical fault-tolerant quantum computing will require powerful and efficient methods to correct for errors in quantum circuits. Here, we explore the role and effectiveness of using noise tailoring techniques to improve the performance of error correcting codes. Noise tailoring methods such as randomized compiling (RC) convert complex coherent noise processes to effective stochastic noise. While it is known that this can be leveraged to design efficient diagnostic tools, we explore its impact on the performance of error correcting codes. Of particular interest is the important class of coherent errors, arising from control errors, where RC has the maximum effect -- converting these into purely stochastic errors. For these errors, we show here that RC delivers an improvement in performance of the concatenated Steane code by several orders of magnitude. We also show that below a threshold rotation angle, the gains in logical fidelity can be arbitrarily magnified by increasing the size of the codes. These results suggest that using randomized compiling can lead to a significant reduction in the resource overhead required to achieve fault tolerance.

description: In the framework of adhesive transformation systems with Negative Application Conditions (NACs), we show how the problem of computing the set of equivalent derivations to a given one can be reduced to the analysis of the reachability graph of a generated Place/Transition Petri net. This net encodes the dependencies among rule applications of the derivation, including the inhibiting effects of the NACs. We show the effectiveness of this approach by comparing the cost of a brute force-approach with the cost of the presented analysis applied to a derivation of a simple system, showing a significant improvement in speed.

description: Graphene nanoribbons (GNRs) are natural waveguides for electrons in graphene. Nevertheless, unlike micron-sized samples, conductance is nearly suppressed in these narrow graphene stripes, mainly due to scattering with edge disorder generated during synthesis or cut. A possible way to circumvent this effect is to define an internal waveguide that isolates specific modes from the edge disorder and allows ballistic conductance. There are several proposals for defining waveguides in graphene; in this manuscript, we consider strain folds and scalar potentials and numerically evaluate these proposals' performance against edge and bulk disorder. Using the Green's function approach, we calculate conductance and the local density of states (LDOS) of zigzag GNRs and characterize the performance of these different physical waveguiding effects in both types of disorder. We found a general improvement in the electronic conductance of GNR due to the presence of the internal waveguiding, with the emergence of plateaus with quasi-ballistic properties and robustness against edge disorder. These findings are up to be applied in modern nanotechnology and being experimentally tested.

description: We propose a model-based geostatistical approach to deal with regionalized compositions. We combine the additive-log-ratio transformation with multivariate geostatistical models whose covariance matrix is adapted to take into account the correlation induced by the compositional structure. Such specification allows the usage of standard likelihood methods for parameters estimation. For spatial prediction we combined a back-transformation with the Gauss-Hermite method to approximate the conditional expectation of the compositions. We analyze particle size fractions of the top layer of a soil for agronomic purposes which are typically expressed as proportions of sand, clay and silt. Additionally a simulation study assess the small sample properties of the maximum likelihood estimator.

Universal self-field critical current for thin-film superconductors

description: For any practical superconductor the magnitude of the critical current density, $J_\textrm{c}$, is crucially important. It sets the upper limit for current in the conductor. Usually $J_\textrm{c}$ falls rapidly with increasing external magnetic field but even in zero external field the current flowing in the conductor generates a self-field which limits $J_\textrm{c}$. Here we show for thin films of thickness less than the London penetration depth, $λ$, this limiting $J_\textrm{c}$ adopts a universal value for all superconductors - metals, oxides, cuprates, pnictides, borocarbides and heavy Fermions. For type I superconductors, it is $H_{\textrm{c}}/λ$ where $H_\textrm{c}$ is the thermodynamic critical field. But surprisingly for type II superconductors we find the self-field $J_\textrm{c}$ is $H_{\textrm{c}1}/λ$ where $H_{\textrm{c}1}$ is the lower critical field. $J_\textrm{c}$ is thus fundamentally determined and this provides a simple means to extract absolute values of $λ(T)$ and, from its temperature dependence, the symmetry and magnitude of the superconducting gap.

description: The principal aim of this thesis was to investigate visitation to Melbourne by regional Victorians with particular emphasis on finding ways to improve visitation to metropolitan parks. This thesis incorporated two theories of leisure participation, from which a conceptual framework was developed. Crawford, Jackson and Godbey's (1991) constraints model and Raymore's (2002) facilitator's framework were used to investigate the decision making process of regional visitors to Melbourne's parks. Earlier quantitative research by Parks Victoria indicated a decline in visitation of both regional Victorians and Melburnians to Melbourne's metropolitan parks between the years 2000 and 2003 (Community Perception Monitor (CPM), 2000 - 2003). This finding produced an opportunity to conduct research into the constraints on metropolitan park use, particularly by regional Victorians. The research was conducted using individual in-depth interviews and focus group discussions to gather the requisite data from both regional Victoria and Melbourne. This information was used to establish recommendations in order to raise interest in visiting Melbourne's metropolitan parks.

description: The photovoltaic effect in a Weyl semimetal due to the adiabatic quantum phase is studied. We particularly focus on the case in which an external ac electric field is applied to the semimetal. In this setup, we show that a photocurrent is induced by the ac electric field. By considering a generalized Weyl Hamiltonian with nonlinear terms, it is shown that the photocurrent is induced by circularly, rather than linearly, polarized light. This photovoltaic current can be understood as an emergent electromagnetic induction in the momentum space; the Weyl node is a magnetic monopole in the momentum space, of which the electric field is induced by the circular motion. This result is distinct from conventional photovoltaic effects, and potentially useful for experimentally identifying Weyl semimetals in chiral crystals.

description: In the present work, we introduce the anodic growth of conical shaped TiO2 nanotube arrays. These titania nanocones provide a scaffold for dye-sensitized solar cell (DSSC) structures with significantly improved photon management, providing an optimized absorption profile compared with conventional cylindrical nanotube arrays. Finite difference time domain (FDTD) modelling demonstrates a drastically changed power-absorption characteristic over the tube length. When used in a back-side illumination DSSC configuration, nanocone structures can reach over 60 % higher solar cell conversion efficiency than conventional tubes. The resulting η of ca. 8 % represents one of the highest reported values for Graetzel type DSSCs used under back-side illumination.

description: Hovering insects are limited by their physiology and need to rotate their wings at the end of each back and forth motion to keep the wing's leading edge ahead of its trailing edge. The wing rotation at the end of each half-stroke pushes the leading edge vortex away from the wing which leads to a loss in the lift. Unlike biological fliers, human-engineered flapping wing micro air vehicles have different design limitations. They can be designed to avoid the end of stroke wing rotation and use so-called water-treading flapping kinematics. Flapping wings using conventional flapping kinematics have a designated leading and trailing edge. In the water-treading mode, the role of the leading and trailing edges are continuously alternated throughout the stroke. Here, we compare velocity field and force measurements for a rectangular flapping wing conducting normal hovering and water-treading kinematics to study the difference in fluid dynamic performance between the two types of flapping kinematics. We show that for similar power consumption, the water-treading mode produces more lift than the conventional hovering mode and is 50% more efficient for symmetric pitching kinematics. In the water-treading mode, the leading edge vortex from the previous stroke is not pushed away but is captured and keeps the newly formed leading edge vortex closer to the wing, leading to a more rapid increase of the lift coefficient which is sustained for longer. This makes the water-treading mode a promising alternative for human-engineered flapping wing vehicles.

description: The COHERENT collaboration observed coherent elastic neutrino nucleus scattering using a 14.6 kg cesium-iodide (CsI) detector in 2017 and recently published the updated results before decommissioning the detector. Here, we present the legacy determination of the weak mixing angle and of the average neutron rms radius of $^{133}\mathrm{Cs}$ and $^{127}\mathrm{I}$ obtained with the full CsI dataset, also exploiting the combination with the atomic parity violation (APV) experimental result, that allows us to achieve a precision as low as $\sim$4.5% and to disentangle the contributions of the $^{133}\mathrm{Cs}$ and $^{127}\mathrm{I}$ nuclei. Interestingly, we show that the COHERENT CsI data show a 6$σ$ evidence of the nuclear structure suppression of the full coherence. Moreover, we derive a data-driven APV+COHERENT measurement of the low-energy weak mixing angle with a percent uncertainty, independent of the value of the average neutron rms radius of $^{133}\mathrm{Cs}$ and $^{127}\mathrm{I}$, that is allowed to vary freely in the fit. Additionally, we extensively discuss the impact of using two different determinations of the theoretical parity non-conserving amplitude in the APV fit. Our findings show that the particular choice can make a significant difference, up to 6.5% on $R_n$(Cs) and 11% on the weak mixing angle. Finally, in light of the recent announcement of a future deployment of a 10 kg and a $\sim$700 kg cryogenic CsI detectors, we provide future prospects for these measurements, comparing them with other competitive experiments that are foreseen in the near future.

Beyond choice: family and kinship in the Australian lesbian and gay 'baby boom'

description: Abstract: Planned parenthood within the lesbian and gay communities attracts considerable attention internationally among researchers, the media, and law and policy-makers. This Australian study situates the phenomenon - also known as the 'gayby boom' - within the contemporary Australian socio-legal setting and the more international historical and political contexts of Gay and Women's Liberation. It investigates how beliefs about nature, kinship, the sexed and reproductive body and political ideologies of family intersect in lesbians and gay men's decision-making and stories of living their lives as parents. Two fields of intellectual enquiry are generative: the interest in families of choice and family practices within sociology and the post-modern anthropological critique of Western kinship in the era of assisted reproduction. This is a qualitative study informed by a critical humanist approach. It is based on in-depth and key informant interviews conducted with 20 lesbians and 15 gay men (parents, 'donor/dads' and prospective parents) as well as 7 people engaged in legal, health or therapeutic support to prospective and current parents. Also incorporated into the analysis are a range of other primary sources, including a substantial media debate, submissions to an assisted reproduction law reform process and primary documents supplied by participants such as parenting agreements and letters. The study argues for the need to look beyond unitary concepts such as families of choice when theorising lesbian and gay parenthood. It is important to consider the historical, political and biographical conditions that make some notions of relatedness and decisions about having children seem more feasible, and indeed, natural than others. It explores how various notions of biological relatedness remain important in the formation of parent/child relationships, and the extent to which lesbians and gay men rely on strategic appeals to choice and biology in enacting families. Continuing constraints on who is eligible for clinically assisted reproductive technology in Australia lead to imaginative and harmonious, yet also fraught reproductive relationships.

description: We classify the rank two commutative semifields which are 8-dimensional over their center $\mathbb{F}_{q}$. This is done using computational methods utilizing the connection to linear sets in $\mathrm{PG}(2,q^{4})$. We then apply our methods to complete the classification of rank two commutative semifields which are 10-dimensional over $\mathbb{F}_{3}$. The implications of these results are detailed for other geometric structures such as semifield flocks, ovoids of parabolic quadrics, and eggs.
