description: The recently discovered ATi$_3$Bi$_5$ (A=Cs, Rb) exhibit intriguing quantum phenomena including superconductivity, electronic nematicity, and abundant topological states, which provide promising platforms for studying kagome superconductivity, band topology, and charge orders. In this work, we comprehensively study various properties of ATi$_3$Bi$_5$ including superconductivity under pressure and doping, band topology under pressure, thermal conductivity, heat capacity, electrical resistance, and spin Hall conductivity (SHC) using first-principles calculations. Calculated superconducting transition temperature ($\mathrm{ T_{c}}$) of CsTi$_3$Bi$_5$ and RbTi$_3$Bi$_5$ at ambient pressure are about 1.85 and 1.92K. When subject to pressure, $\mathrm{ T_{c}}$ of CsTi$_3$Bi$_5$ exhibits a special valley and dome shape, which arises from quasi-two-dimensional to three-dimensional isotropic compression within the context of an overall decreasing trend. Furthermore, $\mathrm{ T_{c}}$ of RbTi$_3$Bi$_5$ can be effectively enhanced up to 3.09K by tuning the kagome van Hove singularities (VHSs) and flat band through doping. Pressure can also induce abundant topological surface states at the Fermi energy ($\mathrm{E}_{\mathrm{F}}$) and tune VHSs across $\mathrm{E}_{\mathrm{F}}$. Additionally, our transport calculations are in excellent agreement with recent experiments, confirming the absence of charge density wave. Notably, SHC of CsTi$_3$Bi$_5$ can reach as large as 226$ \hbar\cdot (e\cdot Ω\cdot cm) ^{-1} $ at $\mathrm{E}_{\mathrm{F}}$. Our work provides a timely and detailed analysis of the rich physical properties for ATi$_3$Bi$_5$, offering valuable insights for further explorations and understandings on these intriguing superconducting materials.

Subjects: subject: Cryptography and Security (cs.CR)

description: The actor network procedures of Pavlovic and Meadows are a recent graphical formalism developed for describing security ceremonies and for reasoning about their security properties. The present work studies the relations of the actor network procedures (ANP) to the recent psi-calculi framework. Psi-calculi is a parametric formalism where calculi like spi- or applied-pi are found as instances. Psi-calculi are operational and largely non-graphical, but have strong foundation based on the theory of nominal sets and process algebras. One purpose of the present work is to give a semantics to ANP through psi-calculi. Another aim was to give a graphical language for a psi-calculus instance for security ceremonies. At the same time, this work provides more insight into the details of the ANPs formalization and the graphical representation.

description: We study an energy-constrained random walker on a length-$N$ interval of the one-dimensional integer lattice, with boundary reflection. The walker consumes one unit of energy for every step taken in the interior, and energy is replenished up to a capacity of~$M$ on each boundary visit. We establish large $N, M$ distributional asymptotics for the lifetime of the walker, i.e., the first time at which the walker runs out of energy while in the interior. Three phases are exhibited. When $M \ll N^2$ (energy is scarce), we show that there is an $M$-scale limit distribution related to a Darling-Mandelbrot law, while when $M \gg N^2$ (energy is plentiful) we show that there is an exponential limit distribution on a stretched-exponential scale. In the critical case where $M / N^2 \to ρ\in (0,\infty)$, we show that there is an $M$-scale limit in terms of an infinitely-divisible distribution expressed via certain theta functions.

description: We demonstrate that self-interacting dark matter models with interactions mediated by light particles can have significant deviations in the matter power-spectrum and detailed structure of galactic halos when compared to a standard cold dark matter scenario. While these deviations can take the form of suppression of small scale structure that are in some ways similar to that of warm dark matter, the self-interacting models have a much wider range of possible phenomenology. A long-range force in the dark matter can introduce multiple scales to the initial power spectrum, in the form of dark acoustic oscillations and an exponential cut-off in the power spectrum. Using simulations we show that the impact of these scales can remain observationally relevant up to the present day. Furthermore, the self-interaction can continue to modify the small-scale structure of the dark matter halos, reducing their central densities and creating a dark matter core. The resulting phenomenology is unique to this type of models.

description: We present a scattering formalism to analyze the spin-momentum locking in structured holey plasmonic metasurfaces. It is valid for any unit cell for arbitrary position and orientation of the holes. The spin-momentum locking emergence is found to originate from the unit cell configuration. Additionally, we find that there are several breakdown terms spoiling the perfect spin-momentum locking polarization. We prove that this breakdown also appears in systems with global symmetries of translation and rotation of the whole lattice, like the Kagome lattice. Finally, we present the excitation of surface plasmon polaritons as the paramount example of the spin-momentum locking breakdown.

description: Recently, personalized federated learning (pFL) has attracted increasing attention in privacy protection, collaborative learning, and tackling statistical heterogeneity among clients, e.g., hospitals, mobile smartphones, etc. Most existing pFL methods focus on exploiting the global information and personalized information in the client-level model parameters while neglecting that data is the source of these two kinds of information. To address this, we propose the Federated Conditional Policy (FedCP) method, which generates a conditional policy for each sample to separate the global information and personalized information in its features and then processes them by a global head and a personalized head, respectively. FedCP is more fine-grained to consider personalization in a sample-specific manner than existing pFL methods. Extensive experiments in computer vision and natural language processing domains show that FedCP outperforms eleven state-of-the-art methods by up to 6.69%. Furthermore, FedCP maintains its superiority when some clients accidentally drop out, which frequently happens in mobile settings. Our code is public at https://github.com/TsingZ0/FedCP.

description: We investigate the reflectivity and optical scattering characteristics at 1064\,nm of an antireflection coated fused silica window of the type being used in the Advanced LIGO gravitational-wave detectors. Reflectivity is measured in the ultra-low range of 5-10\,ppm (by vendor) and 14-30\,ppm (by us). Using an angle-resolved scatterometer we measure the sample's Bidirectional Scattering Distribution Function (BSDF) and use this to estimate its transmitted and reflected scatter at roughly 20-40\,ppm and 1\,ppm, respectively, over the range of angles measured. We further inspect the sample's low backscatter using an imaging scatterometer, measuring an angle resolved BSDF below $10^{-6}$ sr$^{-1}$ for large angles (10$^\circ$--80$^\circ$ from incidence in the plane of the beam). We use the associated images to (partially) isolate scatter from different regions of the sample and find that scattering from the bulk fused silica is on par with backscatter from the antireflection coated optical surfaces. To confirm that the bulk scattering is caused by Rayleigh scattering, we perform a separate experiment, measuring the scattering intensity versus input polarization angle. We estimate that 0.9--1.3\,ppm of the backscatter can be accounted for by Rayleigh scattering of the bulk fused silica. These results indicate that modern antireflection coatings have low enough scatter to not limit the total backscattering of thick fused silica optics.

description: Soft clay-like Li-superionic conductors have been recently synthesized by mixing rigid-salts. Through computational and experimental analysis, we clarify how a soft clay-like material can be created from a mixture of rigid-salts. Using molecular dynamics simulations with a deep learning-based interatomic potential energy model, we uncover the microscopic features responsible for soft clay-formation from ionic solid mixtures. We find that salt mixtures capable of forming molecular solid units on anion exchange, along with the slow kinetics of such reactions, are key to soft-clay formation. Molecular solid units serve as sites for shear transformation zones, and their inherent softness enables plasticity at low stress. Extended X-ray absorption fine structure spectroscopy confirms the formation of molecular solid units. A general strategy for creating soft clay-like materials from ionic solid mixtures is formulated.

description: Active Learning (AL) is a family of machine learning (ML) algorithms that predates the current era of artificial intelligence. Unlike traditional approaches that require labeled samples for training, AL iteratively selects unlabeled samples to be annotated by an expert. This protocol aims to prioritize the most informative samples, leading to improved model performance compared to training with all labeled samples. In recent years, AL has gained increasing attention, particularly in the field of physics. This paper presents a comprehensive and accessible introduction to the theory of AL reviewing the latest advancements across various domains. Additionally, we explore the potential integration of AL with quantum ML, envisioning a synergistic fusion of these two fields rather than viewing AL as a mere extension of classical ML into the quantum realm.

description: Over the last few decades, Indonesia has seen an increase in its food imports and continues to see steady increases due to changing consumer taste and preferences. The current study analysed aggregate food import demand and its determinants using annual data and the ARDL bounds testing approach to cointegration for the period 1984-2020. The Augmented Dicky-Fuller test was used to determine the order of integration of each variable which was found to be order 1 for all variables. The outcome of the unit root test suggested a possible cointegrating relationship between food imports and its determinants which was investigated using the ARDL bounds testing approach. The bounds test concluded that there exists a long-run equilibrium relationship between food imports and its determinants. In both time horizons relative prices, exchange rate and domestic production were found to negatively affect food imports while real income had a positive effect. Food imports for Indonesia was found to be price-inelastic in both time horizons. In addition, imported was found to be a luxury good with income elastic demand in both time horizons. Food import demand was found to be most responsive to changes in real income and domestic production during the study period. The adjustment parameters also suggest that around 92.4% of short- to long-run disequilibrium is corrected each year. Finally, the study suggested that policies to control excessive food import quantity in Indonesia can include setting import quota, giving subsidies to farmers, applying taxes to specific food items and devaluation of currency.

description: Structural variations (SV) can lead to DNA rearrangements and frequently cause diseases such as neurological disorders. SVs account for more total nucleotide changes and occur more frequently than single nucleotide polymorphisms (SNPs) (Stankiewicz and Lupski, 2010). As we continue to gain knowledge, SV has surpassed SNPs in its effects on human evolution, population diversity, and genetic diseases (Stankiewicz and Lupski, 2010). Compared to SNP, SV is more challenging to study due to its complex configuration, large size, and repetitive arrangement. Meanwhile, sequencing technologies including Illumina and Oxford Nanopore sequencing platform are being actively developed to generate sequencing data of human whole genomes, which can then be analyzed to study genetic variations. This series of studies aims to employ contemporary sequencing technologies and computational workflows to unravel the functional impact of SVs.Good tools are prerequisite to the successful execution of a job. My study starts from developing a pipeline construction tool called PipelineDog that can be used throughout the work. PipelineDog is a web-based integrated development environment (IDE) that represents a novel way to arrange and define workflows while promoting code scalability and reusability. I then apply established tools and workflows to analyze a 192-invidual cohort, surveying the large structural genetic etiology of autism spectrum disorder (ASD) and attention-deficit/hyperactivity disorder (ADHD) co-occurrence. Lastly, the newly commercialized Nanopore sequencing technique was tested and evaluated on both existing and simulated data. The Nanopore sequencing is anticipated to improve the SV identification, as it generates longer reads and will enrich the SV determining evidence. I improved the overall SV identification accuracy by employing a random forest machine learning model to classify the combined dataset from different workflows. This analysis shed light on how to determine which SV identification workflow to use based on specific use cases for future projects.
Bounds on the radius and status of graphs

description: Two classical concepts of centrality in a graph are the median and the center. The connected notions of the status and the radius of a graph seem to be in no relation. In this paper, however, we show a clear connection of both concepts, as they obtain their minimum and maximum values at the same type of tree graphs. Trees with fixed maximum degree and extremum radius and status, resp., are characterized. The bounds on radius and status can be transferred to general connected graphs via spanning trees. A new method of proof allows not only to regain results of Lin et al. on graphs with extremum status, but it allows also to prove analogous results on graphs with extremum radius.

We propose a graphical model for cybersecurity risk assessment based on Adversarial Risk Analysis to face those challenges. We also provide an example of the model in the context of an offshore drilling rig. The proposed model provides a more formal and comprehensive analysis of risks, still using the standard business language based on decisions, risks, and value.

Density-dependent relativistic mean field approach and its application to single-$Λ$ hypernuclei in Oxygen isotopes

description: The in-medium feature of nuclear force which includes both nucleon-nucleon ($NN$) and hyperon-nucleon ($ΛN$) interactions impacts the description of single-$Λ$ hypernuclei. With the alternated mass number or isospin of hypernuclei, such effects could be unveiled by analyzing systematical evolution of the bulk and single-particle properties. From a density-dependent meson-nucleon/hyperon coupling perspective, a new $ΛN$ effective interaction in the covariant density functional (CDF) theory, namely DD-LZ1-$\Lambda1$, is obtained by fitting the experimental data of $Λ$ separation energies for several single-$Λ$ hypernuclei. It is then adopted to study the structure and transition properties of single-$Λ$ hypernuclei in Oxygen isotopes, comparing with several selected CDF Lagrangians. Discrepancy is observed explicitly in the isospin evolution of $\Lambda1p$ spin-orbit splitting with various effective interactions, ascribed to their divergence of the meson-hyperon coupling strengths with increasing density. In particular, the density-dependent CDFs introduce an extra contribution to enhance the isospin dependence of the splitting, which is originated from the rearrangement terms of $Λ$ self-energies. In addition, the characteristics of hypernuclear radii are studied along the isotopic chain. Owing to the impurity effect of $Λ$ hyperon, a size shrinkage is observed in the matter radii of hypernuclei as compared to their cores of normal nuclei, while its magnitude is elucidated further to correlate with the incompressibility of nuclear matter. Besides, there exists a sizable model-dependent trend that $Λ$ hyperon radii evolve with the neutron number, which is decided partly by the in-medium $NN$ interactions as well as the core polarization effects.

description: The tensor properties of the algebra generators are determined in respect to the reduction chain $Sp(12,R) \supset U(3,3) \supset U_{p}(3) \otimes \overline{U_{n}(3)}\supset U^{\ast}(3) \supset O(3)$, which defines one of the dynamical symmetry limits of the Interacting Vector Boson Model (IVBM). The symplectic basis according to the considered chain is thus constructed and the action of the $Sp(12,R)$ generators as transition operators between the basis states is illustrated. The matrix elements of the $U(3,3)$ ladder operators in the so obtained symmetry-adapted basis are given. The $U(3,3)$ limit of the model is further tested on the more complicated and complex problem of reproducing the $B(E2)$ transition probabilities between the collective states of the ground band in $^{104}Ru$, $^{192}Os$, $^{192}Pt$, and $^{194}Pt$ isotopes, considered by many authors to be axially asymmetric. Additionally, the excitation energies of the ground and $γ$ bands in $^{104}Ru$ are calculated. The theoretical predictions are compared with the experimental data and some other collective models which accommodate the $γ-$rigid or $γ-$soft structures. The obtained results reveal the applicability of the model for the description of the collective properties of nuclei, exhibiting axially asymmetric features.

description: This paper employs threshold cointegration technique that allows for asymmetric adjust-ment towards a long-run equilibrium relationship in order to examine the relationship between international and domestic prices of wheat in Algeria. The short-run adjustments are also examined with asymmetric error correction models. The analysis is based on annual series of international and domestic wheat prices. The time interval for the study runs from 1965 to 2021 using official data from national and international official organizations. The results indicate that the price transmission between the domestic and international price level of wheat is asymmetric, especially in the presence of structural breaks. The asymmetric error correction model with threshold cointegration provides strong evidence supporting asymmet-ric price behavior. Increases in the international price of wheat are transmitted more quickly to domestic prices than declines, which exhibit the increased vulnerability of the domestic market to be reconsidered.

description: In this paper, we investigate the interaction between early dark energy (EDE) and scalar field dark matter, proposing a coupled scalar fields model to address the Hubble tension and $S_8$ tension. While the EDE model successfully alleviates the Hubble tension, it exacerbates the $S_8$ tension. To mitigate the negative impact of EDE, we introduce the interaction between EDE and dark matter. Specifically, we replace cold dark matter with scalar field dark matter, given its capability to suppress structure growth on small scales. We constrained the new model using cosmological observations including the temperature and polarization anisotropy power spectra data of cosmic microwave background radiation (CMB) from \textit{Planck} 2018 results, baryon acoustic oscillations (BAO) measurements extracted from 6dFGS, SDSS and BOSS, the Pantheon sample of type Ia supernovae (SNIa), the local distance-ladder data (SH0ES), and the Dark Energy Survey Year-3 data. Employing Markov Chain Monte Carlo method, we find that this novel model yields best-fit values of $H_0$ and $S_8$ equal to $71.13$ km/s/Mpc and $0.8256$, respectively. Compared to the $Λ$CDM model, the new model alleviates the Hubble tension but still fails to resolve the $S_8$ tension. However, we obtain a smaller value of $S_8$ compared to the result of $0.8316$ obtained for EDE model, which mitigates to some extent the shortcoming of the EDE model.

description: We study the conditions to realize an excitonic condensed phase in an electron-hole bilayer system with local Hubbard-like interactions at half-filling, where we can address the interplay with Mott localization. Using Dynamical Mean-Field Theory, we find that an excitonic state is stable in a sizeable region of a phase diagram spanned by the intra-layer (U) and inter-layer (V) interactions. The latter term is expected to favour the excitonic phase which is indeed found in a slice of the phase diagram with V > U . Remarkably, we find that when U is large enough, the excitonic region extends also for U > V in contrast with naive expectations. The extended stability of the excitonic phase can be linked to in-layer Mott localization and inter-layer spin correlations. Using a mapping to a model with attractive inter-layer coupling, we fully characterize the condensate phase in terms of its superconducting counterpart, thereby addressing its coherence and correlation length.

description: Context. The previously identified source SSTB213 J041757 is a proto brown dwarf candidate in Taurus, which has two possible components A and B. It was found that component B is probably a class 0/I proto brown dwarf associated with an extended envelope. Aims. Studying molecular outflows from young brown dwarfs provides important insight into brown dwarf formation mechanisms, particularly brown dwarfs at the earliest stages such as class 0, I. We therefore conducted a search for molecular outflows from SSTB213 J041757. Methods. We observed SSTB213 J041757 with the Submillimeter Array to search for CO molecular outflow emission from the source. Results. Our CO maps do not show any outflow emission from the proto brown dwarf candidate. Conclusions. The non-detection implies that the molecular outflows from the source are weak; deeper observations are therefore needed to probe the outflows from the source.

description: Recently discovered regular X-ray bursts known as quasi-periodic eruptions have a proposed model that suggests a tidal stripping white dwarf inspiralling into the galaxy's central black hole on an eccentric orbit. According to this model, the interaction of the stripping white dwarf with the central black hole would emit gravitational wave signals as well, their detection can help explore the formation mechanism of quasi-periodic eruptions and facilitate multi-messenger observations. In this paper, we aim to perform a preliminary study of the gravitation wave observation of TianQin on this stripping white dwarf model. We investigated the horizon distance of TianQin on this type of gravitation wave signal and found it can be set to 200Mpc. We also find that those stripping white dwarf model sources with central black hole mass within $10^4\sim10^{5.5}M_\odot$ are more likely to be detected by TianQin. We assessed the parameter estimation precision of TianQin on those stripping white dwarf model sources. Our result shows that, even in the worst case, TianQin can determine the central black hole mass, the white dwarf mass, the central black hole spin, and the orbital initial eccentricity with a precision of $10^{-2}$. In the optimistic case, TianQin can determine the central black hole mass and the white dwarf mass with a precision of $10^{-7}$, determine the central black hole spin with a precision of $10^{-5}$, and determine the orbital initial eccentricity with a precision of $10^{-8}$. Moreover, TianQin can determine the luminosity distance with a precision of $10^{-1}$ and determine the sky localization with a precision of $10^{-2}\sim10$ $\rm deg^2$.

Multicounty units of observation are considered useful for descriptive, analytical, and policy implication purposes. Four hundred and eighty-nine multicounty trading areas, which include all counties in the 48 contiguous States, were aggregated into five urban-orientation groups. The level of development of an area was found to be correlated with urban orientation. However, the sparsely settled rural areas of the Great Plains, on average, have attained a slightly higher level of economic development than the more densely settled rural areas of the Southeast. Population and employment growth rates are independent of urban orientation or the level of economic development. Economic development policies need to differ for rural areas compared with urban areas and for areas with a higher level of development compared with those with lower levels of development.

description: This article discusses the determinants of monthly food consumption expenditures of households in Mali, using a quintile approach. The study is based on survey data from the EMOP, 2020 on household expenditures. This survey was conducted in the same year among 6703 households in the eight regions of Mali and the District of Bamako. The application of the simultaneous quintile regression yields results indicating that total household expenditures are positively correlated with monthly household food consumption expenditures in the 25th, 50th, and 75th quintiles and also in all regions and the District of Bamako. An increase of one unit in the number of motorcycles in good condition owned by the household and in the number of internet connections would significantly reduce household food expenditures in all three quintiles in Mali. The inter-regional analysis, by OLS, indicates that with the exception of the regions of Koulikoro, Ségou and Kidal, the effect of the number of motorcycles in the other regions is negatively significant. It is most evident in Bamako (12018.88 FCFA), Kayes (10061.8 FCFA) and Timbuktu (5695.76 FCFA). Compared to the other regions, the effect of the cell phone would reduce the food consumption of households in Timbuktu more (5922.22 FCFA).

description: We quantify to what extent tidal erosion of globular clusters (GCs) has contributed to the observed u-shaped relation between GC specific frequencies S_N and host galaxy luminosity M_V. We used our MUESLI code to calculate GC survival rates for typical early-type galaxy potentials covering a wide range of observed galaxy properties. We do this for isotropic and radially anisotropic GC velocity distributions. We find that the calculated GC survival fraction, f_s, depends linearly on the logarithm of the 3D mass density, rho_3D, within the galaxy's half light radius, with f_s proportional to (rho_3D)^(-0.17). For a given galaxy, survival rates are lower for radially anisotropic configurations than for the isotropic GC cases. We apply these relations to a literature sample of 219 early-type galaxies from Harris et al. (2013) in the range M_V=[-24.5:-15.5] mag. The expected GC survival fraction ranges from ~50% for the most massive galaxies with the largest radii to ~10% for the most compact galaxies. We find that intermediate luminosity galaxies M_V=[-20.5:-17.5] mag have the strongest expected GC erosion. Within the considered literature sample, the predicted GC survival fraction therefore defines a u-shaped relation with M_V, similar to the relation between specific frequency S_N and M_V. As a consequence, the u-shape of S_N vs. M_V gets erased almost entirely when correcting the S_N values for the effect of GC erosion. We conclude that tidal erosion is an important contributor to the u-shaped relation between GC specific frequency and host galaxy luminosity. It must be taken into account when inferring primordial star cluster formation efficiencies from observations of GC systems in the nearby universe.

description: Long-term prescribed opioid use for chronic pain is shown to reduce recovery potential and increase risk for dependence, which is contributing to the nationwide opioid crisis. There is a need for an innovative, multidisciplinary approach to address prescription opioid dependence. We propose implementation of a community-based interprofessional registered nurse-physical therapist team (IRNPTT) focused on reduction of opioid dependence in adult patients with chronic lower back pain.

description: Method of the quantum hydrodynamics has been applied in quantum plasmas studies. As the first step in our consideration, derivation of classical semi-relativistic (i. e. described by the Darwin Lagrangian on microscopic level) hydrodynamical equations is given after a brief review of method development. It provides better distinguishing between classic and quantum semi-relativistic effects. Derivation of the classical equations is interesting since it is made by a natural, but not very widespread method. This derivation contains explicit averaging of the microscopic dynamics. Derivation of corresponding quantum hydrodynamic equations is presented further. Equations are obtained in the five-momentum approximation including the continuity equation, Euler and energy balance equations. It is shown that relativistic corrections lead to presence of new quantum terms in expressions for a force field, a work field etc. The semi-relativistic generalization of the quantum Bohm potential is obtained. Quantum part of the energy current, which is an analog of the quantum Bohm potential for the energy evolution equation, is derived. The Langmuir wave dispersion in semi-relativistic quantum plasmas, corresponding to the Darwin Lagrangian, is also considered to demonstrate contribution of semi-relativistic effects on basic plasma phenomenon.

description: A novel cooling mechanism is proposed for neutron stars, based on the recent development in the studies of the QCD phase diagram. Possible appearance of the inhomogeneous chiral phase makes the quark beta decay without gluonic interaction. An estimate of the neutrino emissivity shows the order of $10^{24-26}(T/10^9)^6$(erg cm$^{-3}$ s$^{-1}$) near the phase boundaries, whose efficiency is comparable with the usual quark cooling or pion cooling, but it works only in the limited density region. These features may give another cooling scenario of neutron stars.

description: Identifying how variation in abiotic factors and species traits influence the outcome of ecological interactions is fundamental to our understanding of which processes affect community assembly and structure. My goal in this PhD was to describe how nutrient dynamics, plant physical traits, and chemistry affect plant-insect and plant-plant interactions. I pursued this goal in three different systems with natural history observations, comparative field studies, manipulative greenhouse experiments, analytical chemistry, and bioinformatics. I found that investing nitrogen in one tropical passion vine survival strategy did not come at the cost of strategies. Rather, increased soil nitrogen resulted in richer metabolomes, higher leaf toxin concentrations, longer vines, greater biomass, and more leaves with a superior ability to capture sunlight. Next, I investigated how plant traits facilitate the spread of invasive species in Texas, and what consequences their spread has for local communities. I found that lack of variation among native prickly pear nutritional qualities makes them suitable resources to an invasive cactus moth (Cactoblastis cactorum) that recently established in Texas. These findings have serious implications for prickly pear, and their associated food webs that will soon interact with the expanding invasive moth population. I also studied how competition and allelochemical weapons interact to facilitate spread of Guinea grass, a globally distributed invasive pasture grass, in Texas. I found that shading and allelochemistry by Guinea grass interacted to significantly reduce the recruitment and growth of native plants which results in communities with significantly reduced plant diversity. Finally, I compared passion vine phylogenetic, metabolomic, and quantitative traits to describe the drivers of host specialization by sympatric beetles and caterpillars in Costa Rica. I found that passion vine relatedness correlated with host usage in both groups, and different plant characteristics explained how similar each herbivore assemblage was among available hosts. These studies demonstrated the effects of resource availability on plant trait expression and specialized trophic interactions in different environments. Moreover, this dissertation showcased how the mechanisms which govern individual species interactions scale up to influence community structure on a mosaic phytochemical landscape.

description: Black droplets and black funnels are gravitational duals to states of a large N, strongly coupled CFT on a fixed black hole background. We numerically construct black droplets corresponding to a CFT on a Schwarzchild background with finite asymptotic temperature. We find two branches of such droplet solutions which meet at a turning point. Our results suggest that the equilibrium black droplet solution does not exist, which would imply that the Hartle-Hawking state in this system is dual to the black funnel constructed in \cite{Santos:2012he}. We also compute the holographic stress energy tensor and match its asymptotic behaviour to perturbation theory.

description: We present a neutron diffraction study of NaYbO$_2$, a candidate quantum spin liquid compound hosting a geometrically frustrated triangular lattice of magnetic Yb$^{3+}$ ions. We observe diffuse magnetic scattering that persists to at least 20 K, demonstrating the presence of short-range magnetic correlations in this system up to a relatively high energy scale. Using reverse Monte Carlo and magnetic pair distribution function analysis, we confirm the predominant antiferromagnetic nature of these correlations and show that the diffuse scattering data can be well described by noninteracting layers of XY spins on the triangular lattice. We rule out Ising spins and short-range-ordered stripe or 120$^{\circ}$ phases as candidate ground states of NaYbO$_2$. These results are consistent with a possible QSL ground state in NaYbO$_2$ and showcase the benefit of combined reciprocal- and real-space analysis of materials with short-range magnetic correlations.
