description: Previous theoretical and experimental work has put forward 50-period semiconductor superlattices as fast, true random number generators at room temperature. Their randomness stems from feedback between nonlinear electronic dynamics and stochastic processes that are intrinsic to quantum transitions. This work theoretically demonstrates that shorter superlattices with higher potential barriers contain fully chaotic dynamics over several intervals of the applied bias voltage compared to the 50-periods device which presented a much weaker chaotic behavior. The chaos arises from deterministic dynamics, hence it persists even in the absence of additional stochastic processes. Moreover, the frequency of the chaotic current oscillations is higher for shorter superlattices. These features should allow for faster and more robust generation of true random numbers.

description: We develop a general analytical and numerical framework for estimating intra- and extra-neurite water fractions and diffusion coefficients, as well as neurite orientational dispersion, in each imaging voxel. By employing a set of rotational invariants and their expansion in the powers of diffusion weighting, we analytically uncover the nontrivial topology of the parameter estimation landscape, showing that multiple branches of parameters describe the measurement almost equally well, with only one of them corresponding to the biophysical reality. A comprehensive acquisition shows that the branch choice varies across the brain. Our framework reveals hidden degeneracies in MRI parameter estimation for neuronal tissue, provides microstructural and orientational maps in the whole brain without constraints or priors, and connects modern biophysical modeling with clinical MRI.

description: The phase diagram of the monoaxial chiral helimagnet as a function of temperature (T ) and magnetic field with components perpendicular (H x ) and parallel (H z ) to the chiral axis is theoretically studied via the variational mean field approach in the continuum limit. A phase transition surface in the three dimensional thermodynamic space separates a chiral spatially modulated phase from a homogeneous forced ferromagnetic phase. The phase boundary is divided into three parts: two surfaces of second order transitions of instability and nucleation type, in De Gennes terminology, are separated by a surface of first order transitions. Two lines of tricritical points separate the first order surface from the second order surfaces. The divergence of the period of the modulated state on the nucleation transition surface has the logarithmic behavior typical of a chiral soliton lattice. The specific heat diverges on the nucleation surface as a power law with logarithmic corrections, while it shows a finite discontinuity on the other two surfaces. The soliton density curves are described by a universal function of H x if the values of T and H z determine a transition point lying on the nucleation surface; otherwise, they are not universal.

description: In combinatorics of words, a concatenation of $k$ consecutive equal blocks is called a power of order $k$. In this paper we take a different point of view and define an anti-power of order $k$ as a concatenation of $k$ consecutive pairwise distinct blocks of the same length. As a main result, we show that every infinite word contains powers of any order or anti-powers of any order. That is, the existence of powers or anti-powers is an unavoidable regularity. Indeed, we prove a stronger result, which relates the density of anti-powers to the existence of a factor that occurs with arbitrary exponent. As a consequence, we show that in every aperiodic uniformly recurrent word, anti-powers of every order begin at every position. We further show that every infinite word avoiding anti-powers of order $3$ is ultimately periodic, while there exist aperiodic words avoiding anti-powers of order $4$. We also show that there exist aperiodic recurrent words avoiding anti-powers of order $6$.

description: Aufgrund einer kontinuierlich steigenden Anzahl von Hacker-Angriffen auf die Informationssysteme von Firmen und Institutionen haben Intrusion Detection Systeme als eine neue Sicherheitstechnologie an Bedeutung gewonnen. Diese Systeme überwachen Computer, Netzwerke sowie andere Ressourcen und erzeugen Alarme, wenn Sicherheitsverletzungen entdeckt werden. Leider erzeugen die heutigen Intrusion Detection Systeme im Allgemeinen sehr viele zumeist falsche Alarme. Dies wirft das Problem auf, wie mit dieser Flut falscher Alarme umzugehen ist. Die vorliegende Dissertation präsentiert einen neuen Lösungsansatz für dieses Problem.Von zentraler Bedeutung für diesen Lösungsansatz ist die Vorstellung, dass jeder Alarm eine eindeutige Ursache besitzt. Diese Dissertation macht die Beobachtung, dass ein paar Dutzend Ursachen für über 90% der Alarme verantwortlich sind. Auf diese Beobachtung aufbauend, wird folgende zweistufige Methode für den Umgang mit Intrusion Detection Alarmen vorgeschlagen: Der erste Schritt identifiziert Ursachen, die viele Alarme erzeugen, und der zweite Schritt entfernt diese Ursachen, wodurch die zukünftige Alarmlast zumeist stark gesenkt wird.Alternativ können Alarme, die eine nicht sicherheitsrelevante Ursache besitzen, durch Filter automatisch entfernt werden. Um das Aufdecken von Alarmursachen zu unterstützen, stellen wir eine neue Data Mining Methode zum Clustern von Alarmen vor. Die Grundlage für diese Methode besteht darin, dass sich die meisten Ursachen in Alarmgruppen mit charakteristischen strukturellen Eigenschaften manifestieren. Wir formalisieren diese strukturellen Eigenschaften und stellen eine Clustering Methode vor, die Alarmgruppen mit diesen Eigenschaften findet. Im Allgemeinen ermöglichen es solche Alarmgruppen, die zugrunde liegenden Alarmursachen zu identifizieren. Daran anschließend können die identifizierten Ursachen eliminiert oder falsche Alarme herausgefiltert werden. In beiden Fällen sinkt die Zahl der Alarme, die in Zukunft noch ausgewertet werden müssen.Die vorgestellte Methode zum Umgang mit Alarmen wird in Experimenten mit Alarmen aus 16 verschiedenen Intrusion Detection Installationen getestet. Diese Experimente bestätigen, dass es die beschriebene Alarm Clustering Methode sehr einfach macht Ursachen aufzudecken. Außerdem zeigen die Experimente, dass die Alarmlast um durchschnittlich 70% gesenkt werden kann, wenn auf die identifizierten Alarmursachen in angemessener Weise reagiert wird.

description: Emergence of the drug resistant variants of the Influenza A virus in the recent years has aroused a great need for the development of novel neuraminidase inhibitors for controlling the pandemic. The neuraminidase (NA) protein of the influenza virus has been the most potential target for the anti-influenza. However, in the absence of any experimental structure of the drug targeting NA protein of H1N1 influenza A virus as zanamivir and oseltamivir, the comprehensive study of the interaction of the drug molecules with the target protein has been missing. Hence in this study a computational 3-D structure of neuraminidase of H1N1 influenza A virus has been developed using homology modeling technique, and the same was validated for its reliability by ProSA web server in term of energy profile & Z scores and PROCHECK program followed by Ramachandran plot. Further, the developed 3-D model had been employed for docking studies with the class of compounds as Piceid and its analogs. In this context, two novel compounds (ChemBank ID 2110359 and 3075417) were found to be more potent inhibitors of neuraminidase than control drugs as zanamivir and oseltamivir in terms of their robust binding energies, strong inhibition constant (Ki) and better hydrogen bond interactions between the protein-ligand complex. The interaction of these compounds with NA protein has been significantly studied at the molecular level.

Immunogenic and functional characterization of Toxoplasma gondii surface antigens (SAG1 and SAG2)

description: Toxoplasmosis is a zoonotic infection caused by the protozoan parasite Toxoplasma gondii. Among the different forms involved in the parasite’s life cycle, tachyzoites are the most infectious and known to infect a wide variety of tissues to produce inflammatory responses. Two of the most abundant cell surface proteins on the tachyzoite surface, SAG1 and SAG2, are known to play important role during the invasion of host cells. In order to explore the potential of using SAG1 and SAG2 antigens in diagnosis and vaccine development, a recombinant DNA for a chimeric SAG1/2 gene was constructed and the fusion protein was produced in the yeast Pichia pastoris. The sensitivity and specificity of the fusion protein as an antigen were confirmed through western blotting using serum from toxoplasmosis positive individuals. The immunogenicity of the recombinant protein was seen in immunized mice, where specific antibodies were detected. Splenocytes from immunized mice readily proliferate and secrete large amount of IFN-γ when stimulated with the total lysate antigen of tachyzoite, suggesting that a T helper 1 type immune response was induced. Immunized mice have a higher survival rate when challenged with virulent tachyzoites (RH strain) compared to control (non-protein immunized) mice. This suggests that the chimeric protein is potentially a good candidate for diagnostic and vaccine development against T. gondii. Since SAG1 and SAG2 are known to play a role in tachyzoite invasion, the effect of silencing these two genes using RNA interference on host tissue invasion was examined. The siRNA molecules were able to downregulate the expression of both SAG1 and SAG2 in tachyzoites when compared to controls. However, the silencing of SAG1 and SAG2 appears to have little effect on the invasion of host cells by tachyzoites. This suggests that host cell invasion by tachyzoites may not depend on SAG1 and SAG2 alone but other surface antigens and/or secreted proteins might be involved.

description: Precision measurements of the 125 GeV Higgs resonance recently discovered at the LHC have determined that its properties are similar to the ones of the Standard Model (SM) Higgs boson. However, the current uncertainties in the determination of the Higgs boson couplings leave room for significant deviations from the SM expectations. In fact, if one assumes no correlation between the top-quark and gluon couplings to the Higgs, the current global fit to the Higgs data lead to central values of the Higgs couplings to the bottom-quark and the top-quark that are about 2 $σ$ away from the SM predictions. In a previous work, we showed that such a scenario could be realized in the Next to Minimal Supersymmetric extension of the SM (NMSSM), for heavy singlets and light MSSM-like Higgs bosons and scalar top quarks, but for couplings that ruined the perturbative consistency of the theory up to the GUT scale. In this work we show that a perturbative consistent scenario, for somewhat heavier stops, may be obtained in the presence of light singlets. An interesting bonus of this scenario is the possibility of explaining an excess of events observed in CP-even Higgs searches at LEP2.

Treatment of articulation disorders in children with cleft palate: evidence for using electropalatography
Creators: name: Maine, Sarah

Year: 2023

description: Children born with cleft palate are at a high risk for articulation disorders. Electropalatography (EPG) has emerged as a tool that utilises visual feedback to treat persistent articulation disorders in the cleft palate population. The purpose of this paper is to summarise the current research exploring the use of EPG therapy for children with surgically repaired cleft palate and inform clinicians on the quality of evidence available to guide their clinical practice. A search of the literature identified six articles appropriate for inclusion in the review. The review found that although some evidence exists for the efficacy of EPG therapy, further research should be carried out to form a more robust evidence base prior to initiation of a randomised controlled trial.
Dimethylsulphoniopropionate (DMSP) production of Gephyrocapsa oceanica in response to environmental forcing

description: Dimethyl sulphide (DMS) is an important trace gas, both for its contribution to the global sulphur cycle and also, when oxidised in the atmosphere to sulphates, for its potential to alter the properties of clouds and so potentially affect climate. The precursor to DMS, dimethylsulphoniopropionate (DMSP), is produced by a number of marine micro-algae. This study investigated the role of temperature (10-30C), salinity (20-45), photosynthetically active radiation (PAR, 0-2000+ micromol photons m-2 s-1), daylength, rapidly varying light intensity, CO2 concentration and ambient PAR, ultraviolet A and B exposures on the physiology and production of DMSP in the coccolithophore Gephyrocapsa oceanica. Increasing temperature or CO2 concentration led to decreased cellular DMSP and net DMSP production. Increased PAR, up to the point of photoinhibition (which for G. oceanica} is about 1200 micromol photons m-2 s-1), daylength, salinity and potentially UVR were associated with increased cellular DMSP. Increased PAR above that causing photoinhibition resulted in decreased cellular and net DMSP production. The rate of photosynthetic carbon fixation was modelled as a function of incident light, temperature and CO2 concentration. While the photochemistry of photosystems I and II is essentially temperature independent, the process of carbon assimilation is not. The cell must continually match the photochemical production of reactive oxygen species (ROS) and reductant with the ability of the Calvin-Benson cycle to utilise this reductant to fix carbon, as this is not possible, an antioxidant system is also required. Low temperatures, and/or low CO2 concentrations, both of which reduce the carbon fixation rate, and/or increased PAR, UVR and/or salinity all potentially lead to an increased need for an antioxidant system to be up-regulated and vice versa. Both the experimental and modelling results obtained are consistent with the hypothesis that DMSP acts as such an antioxidant within the cell, and for salinity, that it may act both as an antioxidant and a compatible osmolyte.

description: The Neumann problem of linear elasticity is singular with a kernel formed by the rigid motions of the body. There are several tricks that are commonly used to obtain a non-singular linear system. However, they often cause reduced accuracy or lead to poor convergence of the iterative solvers. In this paper, different well-posed formulations of the problem are studied through discretization by the finite element method, and preconditioning strategies based on operator preconditioning are discussed. For each formulation we derive preconditioners that are independent of the discretization parameter. Preconditioners that are robust with respect to the first Lamé constant are constructed for the pure displacement formulations, while a preconditioner that is robust in both Lamé constants is constructed for the mixed formulation. It is shown that, for convergence in the first Sobolev norm, it is crucial to respect the orthogonality constraint derived from the continuous problem. Based on this observation a modification to the conjugate gradient method is proposed that achieves optimal error convergence of the computed solution.
Applications of high performance computing, grid and data technologies to computational geodynamics in Australia

description: This thesis demonstrates and examines computational geodynamics research workflows and outcomes, highlighting improved efficiency and collaboration through facilitation of and streamlined access to key resources. The influence of a buoyant oceanic plateau or mantle plume head interacting with a subduction zone was investigated by conducting three-dimensional numerical simulations at High Performance Computing (HPC) facilities. Model results reveal that these buoyant features can play a significant role in the geodynamics of a subduction zone. In the region of a strongly buoyant plateau or plume head, for a weak slab local trench advance results in an arcuate trench shape and a tear forms in the subducted portion of the slab. The slab tear provides a potential conduit for plume material to transfer to the overriding plate, and local trench advance associated with a large strongly buoyant plume head may contribute to orogenesis. Contributions made to the development of a customised grid compute job submission client template have reduced uptake barriers, enabled easier access to and increased awareness of the geodynamics software used. Participation in the development of software behind a national data sharing service used to share model data with collaborators is also identified as of benefit to the wider Australian geoscience research community.

description: We describe a class of fixed polyominoes called $k$-omino towers that are created by stacking rectangular blocks of size $k\times 1$ on a convex base composed of these same $k$-omino blocks. By applying a partition to the set of $k$-omino towers of fixed area $kn$, we give a recurrence on the $k$-omino towers therefore showing the set of $k$-omino towers is enumerated by a Gauss hypergeometric function. The proof in this case implies a more general hypergeometric identity with parameters similar to those given in a classical result of Kummer.
Syntheses and reactivity studies of phosphaalkynes and low oxidation state p-block heterocycles
Creators: name: Choong, Sam Lim
Publisher: name: Monash University
Year: 2017
Subjects: Uncategorized

description: The research described within this thesis revolves around two central themes, the reactivity of phosphaalkynes towards various substrates, and the synthesis and further studies of novel low valent group 13 and group 14 element complexes. The first chapter provides a general introduction to important concepts and molecules pertinent to the studies discussed herein, and provides a brief overview into the history of phosphaalkynes. Chapter 2 describes the synthesis of a series of 3H-1,2,3,4-triazaphospholes via a regiospecific pathway between phosphaalkynes and organic azides. Such [2+4] cycloadditions have shown marked similarities to Sharpless’s alkyne-azide click reactions, and had prompted interest in exploring them as high yielding routes in accessing new multidentate N/P ligands. Chapter 3 concentrates on coupling reactions between phosphaalkynes and amidinato stabilised group 14 element(I) dimers, as there were no examples of such reactions in the literature at the outset of this study. These reactions have typically yielded unusual systems, and some preliminary theoretical studies and experimental work has gone into understanding the electronic nature of these products. The research for Chapter 4 concerns itself with the use of sterically encumbering beta-diketiminato ligands in accessing new low valent gallium and group 14 element N-heterocycles. Finally, Chapter 5 looks at the reversible hydrogermylation of tert-butyl phosphaalkyne, tBuC≡P, by a beta-diketiminato stabilised germanium(II) hydride to give a novel C-germaphosphaalkene regioselectively.

description: We revisit and analyze the thermodynamic efficiency of the Feynman-Smoluchowski (FS) ratchet, a classical thought experiment describing an autonomous heat-work converter. Starting from the full kinetics of the FS ratchet and deriving the exact forms of the hidden dissipations resulting from coarse-graining, we restate the historical controversy over its thermodynamic efficiency. The existence of hidden entropy productions implies that the standard framework of stochastic thermodynamics applied to the coarse-grained descriptions fails in capturing the dissipative feature of the system. In response to this problem, we explore an extended framework of stochastic thermodynamics to reconstruct the hidden entropy production from the coarse-grained dynamics. The approach serves as a key example of how we can systematically address the problem of thermodynamic efficiency in a multi-variable fluctuating non-equilibrium system.

description: The purpose of this paper is to study reducibility properties in Sasakian geometry. First we give the Sasaki version of the de Rham Decomposition Theorem; however, we need a mild technical assumption on the Sasaki automorphism group which includes the toric case. Next we introduce the concept of {\it cone reducible} and consider $S^3$ bundles over a smooth projective algebraic variety where we give a classification result concerning contact structures admitting the action of a 2-torus of Reeb type. In particular, we can classify all such Sasakian structures up to contact isotopy on $S^3$ bundles over a Riemann surface of genus greater than zero. Finally, we show that in the toric case an extremal Sasaki metric on a Sasaki join always splits.

description: Despite the widespread use of silicon in modern technology, its peculiar thermal expansion is not well-understood. Adapting harmonic phonons to the specific volume at temperature, the quasiharmonic approximation, has become accepted for simulating the thermal expansion, but has given ambiguous interpretations for microscopic mechanisms. To test atomistic mechanisms, we performed inelastic neutron scattering experiments from 100-1500K on a single-crystal of silicon to measure the changes in phonon frequencies. Our state-of-the-art ab initio calculations, which fully account for phonon anharmonicity and nuclear quantum effects, reproduced the measured shifts of individual phonons with temperature, whereas quasiharmonic shifts were mostly of the wrong sign. Surprisingly, the accepted quasiharmonic model was found to predict the thermal expansion owing to a fortuitous cancellation of contributions from individual phonons.

description: The comparative law was born in Italy as a "revolt" against formalism and against dogmatism. What is left of that spirit? The comparison is a cognitive process. From this we derive some consequences. 1. There are no discipline perimeters; 2. Plurality of methodological approaches; 3. Interdisciplinary; 4. Innovation; 5. More attention to the process than to the discipline in legal education; 6 The comparison must show the dynamics of power and highlight the underlying values of the various options.

description: A geodesic orbit manifold (GO manifold) is a Riemannian manifold (M,g) with the property that any geodesic in M is an orbit of a one-parameter subgroup of a group G of isometries of (M,g). The metric g is then called a G-GO metric in M. For an arbitrary compact homogeneous manifold M=G/H, we simplify the general problem of determining the G-GO metrics in M. In particular, if the isotropy representation of H induces equivalent irreducible submodules in the tangent space of M, we obtain algebraic conditions, under which, any G-GO metric in M admits a reduced form. As an application we determine the U(n)-GO metrics in the complex Stiefel manifolds V_k(C^n).

description: In this research, anomaly detection techniques and artificial neu-ral networks were employed to address the issue of attacks on cluster com-puting systems. The study investigated the detection of Distributed Denial of Service (DDoS) and Partition attacks by monitoring metrics such as network latency, data transfer rate, and number of connections. Additionally, out-lier detection algorithms, namely Local Outlier Factor (LOF) and COF, as well as ARIMA and SHESD models were tested for anomaly detection. Two types of neural network architectures, multi-layer perceptron (MLP) and re-cursive LSTM networks, were used to detect attacks by classifying events as “attack” or “no attack”. The study underscores the importance of imple-menting proactive security measures to protect cluster computing systems from cyber threats.

description: We study closed-string moduli stabilization in Higgs-otic inflation in Type IIB orientifold backgrounds with fluxes. In this setup large-field inflation is driven by the vacuum energy of mobile D7-branes. Imaginary selfdual (ISD) three-form fluxes in the background source a $μ$-term and the necessary monodromy for large field excursions while imaginary anti-selfdual (IASD) three-form fluxes are sourced by non-perturbative contributions to the superpotential necessary for moduli stabilization. We analyze Kähler moduli stabilization and backreaction on the inflaton potential in detail. Confirming results in the recent literature, we find that integrating out heavy Kähler moduli leads to a controlled flattening of the inflaton potential. We quantify the flux tuning necessary for stability even during large-field inflation. Moreover, we study the backreaction of supersymmetrically stabilized complex structure moduli and the axio-dilaton in the Kähler metric of the inflaton. Contrary to previous findings, this backreaction can be pushed far out in field space if a similar flux tuning as in the Kähler sector is possible. This allows for a trans-Planckian field range large enough to support inflation.

A structure theorem for abelian quasi-ordered groups
Creators: name: Lehéricy, Gabriel
Publisher: name: arXiv
Year: 2016
Subjects: subject: Logic (math.LO)
subject: FOS: Mathematics

description: We introduce a notion of compatible quasi-ordered groups which unifies valued and ordered abelian groups. It was proved in a paper by Fakhruddin that a compatible quasi-order on a field is always either an order or a valuation. We show here that the group case is more complicated than the field case and describe the general structure of a compatible quasi-ordered abelian group. We also develop a notion of quasi-order-minimality and establish a connection with C-minimality, thus answering a question of F.Delon.

description: Using Wannier functions to represent the density functional results we calculate the hybridization corrections to the orbital momentum operator in the Os 5d shell of Mott insulators Ba2NaOsO6 and Ba2YOsO6. The g-factors are obtained by evaluating the spin and orbital momentum operators in the atomic ground states of the Os ion. While the hybridization corrections play minor role in d3 ion of Ba2YOsO6 with dominant spin moment, they are instrumental for observation of non- zero g-factor of the d1 ions of Ba2NaOsO6. In addition we analyze the exchange interactions in Ba2YOsO6 and find them consistent with the reported magnetic structure.

description: Flowers and leaves of three plants from Leguminosae family (Caesalpiniodeae subfamily), namely Bauhinia kockiana, Caesalpinia pulcherrima and Cassia surattensis were screened for their bioactivities such as antibacterial, cytotoxicity and antioxidant activities. Antibacterial activity was determined using disc diffusion (Kirby-Bauer) and macrobroth dilution methods, while the cytotoxicity was assessed using MTT cell viability assay. Antioxidant properties were evaluated by determining the total phenolic (TPC), total flavonoid (TFC), total anthocyanin (TAC) contents and various antioxidant activity assays (2,2-diphenyl-1-picrylhydrazyl radical scavenging, ferric reducing power, ferrous ion chelating and lipid peroxidation inhibition). It was found that the plant extracts exhibited moderate antibacterial activity, with MIC values in the range 100 - 230 µg/mL. All extracts exhibited moderate cytotoxicity towards MCF-7 breast cancer cells, and the GI50 values ranged from 25 - 49 µg/mL. It was found that C. pulcherrima displayed the strongest cytotoxicity (26 - 32 µg/mL), followed by B. kockiana (32 - 45 µg/mL) and C. surattensis (43 - 49 µg/mL). B. kockiana flower was found to possess the highest TPC (8280 ± 498 mg GAE/100g), free radical scavenging activity (AEAC 14600 ± 2360 mg AA/100 g) and reducing ability (72.4 ± 8.7 mg GAE/g). C. pulcherrima leaf displayed the highest ferrous ion chelating and lipid peroxidation inhibition activities. Bioassay-guided (based on anti-MRSA and cytotoxicity) fractionation and isolation of bioactive phytochemicals from ethyl acetate and methanol extracts of B. kockiana flower afforded two phenolic compounds, namely gallic acid and methyl gallate. This is the first report on the presence of these two phenol constituents from B. kockiana. Antibacterial activity against MRSA by gallic acid and methyl gallate was examined and it was found that methyl gallate exhibited stronger antibacterial activity (MIC values 237 - 373 µg/mL) than gallic acid (MIC values 363 - 560 µg/mL). The cytotoxicity of gallic acid and methyl gallate was evaluated in five cancer cell lines : breast (MCF-7), prostate (PC-3, LNCaP and DU145) and colon (HCT-116). It was found that gallic acid is more cytotoxic than methyl gallate, whereby it displayed moderate cytotoxicity towards MCF-7 and PC-3 cell lines. Weak cytotoxicity towards LNCaP and HCT-116 cell lines was observed but it was not active against DU145 cell line. Observation under fluorescence microscopy of gallic acid treated PC-3 cells stained with acridine orange (AO) and propidium iodide (PI) showed that gallic acid induces apoptosis in PC-3 cells in dose-dependent manner.

description: Directional detection is an important way to detect dark matter. An input to these experiments is the dark matter velocity distribution. Recent hydrodynamical simulations have shown that the dark matter velocity distribution differs substantially from the Standard Halo Model. We study the impact of some of these updated velocity distribution in dark matter directional detection experiments. We calculate the ratio of events required to confirm the forward-backward asymmetry and the existence of the ring of maximum recoil rate using different dark matter velocity distributions for $^{19}$F and Xe targets. We show that with the use of updated dark matter velocity profiles, the forward-backward asymmetry and the ring of maximum recoil rate can be confirmed using a factor of $\sim$2 - 3 less events when compared to that using the Standard Halo Model.
