description: We explore in this paper the phenomenon of photofocusing: a coupling between flow vorticity and biased swimming of microalgae toward a light source that produces a focusing of the microswimmer suspension. We combine experiments that investigate the stationary state of this phenomenon as well as the transition regime with analytical and numerical modeling. We show that the experimentally observed scalings on the width of the focalized region and the establishment length as a function of the flow velocity are well described by a simple theoretical model.

description: Non­standard language such as novel words or creative spellings of existing ones often occurs in natural text corpora, posing significant challenges for natural language processing (NLP) models. While humans can successfully infer the meaning communicated in such non­standard ways, NLP models largely discard linguistic innovation as noise, ignoring its fundamentally non­random nature and losing valuable context. In this thesis, we focus on computational modeling of such creative phenomena, aiming to both improve the automatic processing of non­standardized text data and to learn more about the linguistic and cognitive factors that allow humans to produce and understand novel linguistic items. We present empirical studies of several phenomena under the umbrella of nonstandard language, characterized in terms of different linguistic units (orthographic, morphological, or lexical) and considered at different levels of granularity (from individual users to entire dialects or languages). First, we show how idiosyncratic spelling preferences reveal information about the user, with an application to the bibliographic task of identifying typesetters of historical printed documents. Second, we discuss the common patterns in user­specific orthographies and demonstrate that incorporating these patterns helps with unsupervised conversion of idiosyncratically romanized text into the conventional orthography of the language. Third, we consider word emergence in a dialect or language as a whole and, in two diachronic corpora studies, model the language­internal and language­external factors that drive it. Finally, we look at how continuous emergence of novel words is reconciled with the existing system of morphological rules, focusing on generalization to unseen lemmas in morphological inflection in several languages.

description: The change of the distribution function of electron-positron pair beams determines whether GeV photons can be produced as secondary radiation from TeV photons. We will discuss the instabilities driven by pair beams. The system of a thermal proton-electron plasma and the electron-positron beam is collision free. We have, therefore, used the Particle-in-Cell simulation approach. It was necessary to alter the physical parameters, but the ordering of growth rates has been retained. We were able to show that plasma instabilities can be recovered in particle-in-cell simulations, but their effect on the pair distribution function is negligible for beam-background energy density ratios typically found in blazars.
Aerodynamic analysis and design optimization of variable camber piezocomposite rotors

description: Multi-rotor vehicles use complex mechanisms and/or mechanical components and varying rotor speeds to attain stability, control, and maneuverability. This research proposes that the thrust generated by a rotor can be varied by morphing its blades without the use of mechanisms, and without varying the rotor speed. This method is faster to change thrust and it requires fewer mechanical components. This mechanism-free concept is referred to as the Solid-State Rotor in the literature. The concept employs morphing blades with strain-inducing actuators such as the Macro-Fiber Composite device. This concept can be applied to various aerial vehicles such as single/multi-rotor vehicles, ducted fans, turbines, and other rotary systems interacting with a fluid.The overall goal of this research is to understand and analyze the concept of shape morphing using piezocomposite actuators. To this end, a solid-state rotor system is used, which contains rotating electronics required to power the actuators. The electronics are powered by an electromagnetic generator that is attached to the rotor. The excitation of the piezocomposite actuators on the rotor blades changes the camber of the rotor blades which leads to the change in thrust.In this thesis, first the theoretical models are examined to predict the aerodynamic performance of variable camber piezocomposite rotors. Next, a variable camber piezocomposite rotor is designed and experimentally tested. Finally, a variable-camber variable-pitch piezocomposite hybrid rotor is designed and experimentally tested.

description: Motivated by recent reports of a quantum disordered ground state in the triangular lattice compound NaRuO$_2$, we derive a $j_{\rm eff}=1/2$ magnetic model for this system by means of first-principles calculations. The pseudospin Hamiltonian is dominated by bond-dependent off-diagonal $Γ$ interactions, complemented by a ferromagnetic Heisenberg exchange and a notably antiferromagnetic Kitaev term. In addition to bilinear interactions, we find a sizable four-spin ring exchange contribution with a strongly anisotropic character, which has been so far overlooked when modeling Kitaev materials. The analysis of the magnetic model, based on the minimization of the classical energy and exact diagonalization of the quantum Hamiltonian, points toward the existence of a rather robust easy-plane ferromagnetic order, which cannot be easily destabilized by physically relevant perturbations.

description: Red blood cells (RBCs) have been extensively studied as a potential biotherapeutic delivery system for several decades. This research has been prompted by these cells' remarkable properties. RBCs are incredibly tenacious and robust, possessing the high mechanical flexibility needed to flow through the human vasculature for 120 days. Their unusual biconcave shape gives them a high surface-area-to-volume ratio, and the expression of a variety of immunomodulatory markers on the RBC membrane allows for excellent biocompatibility and low immunogenicity. Coupling a therapeutic protein to the RBC surface has the potential to enhance its pharmacokinetics as well as modulate its immune response. The goal of this work was to explore a chemistry-oriented approach to synthesizing RBC-based drug delivery systems. Covalent crosslinking to the RBC membrane is ideal for prolonging the circulation of biotherapeutics with intravascular drug targets. Donor or autologous blood can be modified ex vivo with a method that is rapid, tunable, and cell-tolerated. In Chapter 2, we synthesized an RBC platform that could stably display almost any therapeutic antibody. Our system consisted of an RBC covalently coupled to Protein A (SpA) via a polyethylene glycol (PEG) crosslinker. The antibody was then presented on the RBC surface by SpA binding at its Fc region. In Chapter 3, we directly tethered butyrylcholinesterase (BChE) via PEG to the RBC membrane to develop an improved prophylactic treatment against organophosphate nerve agents. After the synthesis of each RBCPEG-protein construct, we confirmed that the therapeutic was still active once displayed on the surface and performed a series of in vitro assays to assess the impact of engineering on cell health. Finally, in Chapter 4, we began preliminary studies exploring the use of atom-transfer radical polymerization (ATRP) for RBC-biotherapeutic coupling. Our results provide early evidence that chemical conjugation can be a viable approach for RBC-based drug delivery systems. In future work, we plan to use an animal model to test the safety, toxicity, and efficacy of our RBC-biotherapeutic platforms.

description: This article presents a coupled magneto-thermo-mechanical model of pressure-dependent Magneto-caloric Effect (MCE) and magnetization responses for polycrystalline Magnetic Shape Memory Alloys (MSMA). Coupled constitutive equations are derived from a Helmholtz free energy function in a consistent thermodynamic way. The hysteretic and dissipative characteristics of phase transformations in MSMAs are captured by the internal state variables approach with their evolution equations. The model is calibrated and validated with the existing experimental data. The validated constitutive model is then exploited to predict MCEs at different pressures and magnetic field levels. Some predicted results are compared with the available experimental data.

description: We define Maslov--type indices associated to contact and symplectic transformation groups. There are two such families of indices. The first class of indices are maps from the homotopy groups of the contactomorphism or symplectomorphism group to a quotient of the integers. These are based on a generalization of the Maslov index. The second class of indices are maps from the homotopy groups of the space of contact structures or the space of cohomologous symplectic forms to the homotopy groups of a simple homogeneous space. We provide a detailed construction and describe some properties of these indices and their applications.

description: We describe the development of a Quantum Interactive Learning Tutorial (QuILT) on quantum key distribution, a context which involves a practical application of quantum mechanics. The QuILT helps upper-level undergraduate students learn quantum mechanics using a simple two state system and was developed based upon the findings of cognitive research and physics education research. One protocol used in the QuILT involves generating a random shared key over a public channel for encrypting and decrypting information using single photons with non-orthogonal polarization states, and another protocol makes use of two entangled spin-1/2 particles. The QuILT uses a guided approach and focuses on helping students build links between the formalism and conceptual aspects of quantum physics without compromising the technical content. We also discuss findings from a preliminary in-class evaluation.

description: In this work, we investigate the viability of a light Higgs ($η$) scenario in the Georgi-Machacek (GM) model, where we consider all theoretical and experimental constraints such as the perturbativity, vacuum stability, unitarity, electroweak precision tests, the Higgs di-photon and undetermined decays and the Higgs total decay width. In addition, we consider more recent experimental bounds from the searches for doubly-charged Higgs bosons in the VBF channel $H_{5}^{++}\rightarrow W^{+}W^{+}$, Drell-Yan production of a neutral Higgs boson $pp\rightarrow H_{5}^{0}(γγ)H_{5}^{+}$, and for the light scalars at LEP $e^{-}e^{+}\rightarrow Zη$, and at ATLAS and CMS in different final states such as $pp\rightarrowη\rightarrow2γ$ and $pp\rightarrow h\rightarrowηη\rightarrow4γ,2\mu2τ,2\mu2b,2\tau2b$. By combining these bounds together, we found a parameter space region that is significant as the case of the SM-like Higgs to be the light CP-even eigenstate, and this part of the parameter space would be tightened by the coming analyses.

description: A major challenge when using k-means clustering often is how to choose the parameter k, the number of clusters. In this letter, we want to point out that it is very easy to draw poor conclusions from a common heuristic, the "elbow method". Better alternatives have been known in literature for a long time, and we want to draw attention to some of these easy to use options, that often perform better. This letter is a call to stop using the elbow method altogether, because it severely lacks theoretic support, and we want to encourage educators to discuss the problems of the method -- if introducing it in class at all -- and teach alternatives instead, while researchers and reviewers should reject conclusions drawn from the elbow method.

description: A lock-in amplifier is a versatile instrument frequently used in physics research. However, many students struggle with the basic operating principles of a lock-in amplifier which can lead to a variety of difficulties. To improve students' understanding, we have been developing and evaluating a research-based tutorial which makes use of a computer simulation of a lock-in amplifier. The tutorial is based on a field-tested approach in which students realize their difficulties after predicting the outcome of simulated experiments involving a lock-in amplifier and check their predictions using the simulated lock-in amplifier. Then, the tutorial guides and helps students develop a coherent understanding of the basics of a lock-in amplifier. The tutorial development involved interviews with physics faculty members and graduate students and iteration of many versions of the tutorial with professors and graduate students. The student difficulties and the development and assessment of the research-based tutorial are discussed.

description: Social network research has begun to take advantage of fine-grained communications regarding coordination, decision-making, and knowledge sharing. These studies, however, have not generally analyzed how external events are associated with a social network's structure and communicative properties. Here, we study how external events are associated with a network's change in structure and communications. Analyzing a complete dataset of millions of instant messages among the decision-makers in a large hedge fund and their network of outside contacts, we investigate the link between price shocks, network structure, and change in the affect and cognition of decision-makers embedded in the network. When price shocks occur the communication network tends not to display structural changes associated with adaptiveness. Rather, the network "turtles up". It displays a propensity for higher clustering, strong tie interaction, and an intensification of insider vs. outsider communication. Further, we find changes in network structure predict shifts in cognitive and affective processes, execution of new transactions, and local optimality of transactions better than prices, revealing the important predictive relationship between network structure and collective behavior within a social network.

description: The global decline in arthropod populations is a growing ecological concern because of its consequences on ecosystem stability and functioning. Research is needed to understand the causes of changes in arthropod diversity. Here, we investigated the impact of variation in precipitation on arthropod diversity (i.e., total abundance and trophic guild abundance), along a geographical gradient in the Atacama Desert in Chile. We found that the abundance of arthropods was higher in the site with the lowest precipitation, which points to a complex interplay of ecological factors that may include resource availability, microclimate conditions, adaptation strategies, and behaviors that arthropods use to survive in the challenging environmental conditions of the Atacama Desert. In addition, with the exception of predators, arthropod abundance across sites differed between trophic guilds. The site with the greatest plant diversity,cover, and precipitation contained the greatest number of detritivores. These findings highlight the significance of precipitation and plant cover on arthropod diversity. The implications of our research could be extended to ecosystem management and conservation as these can guide.

description: This paper presents a data compression algorithm with error bound guarantee for wireless sensor networks (WSNs) using compressing neural networks. The proposed algorithm minimizes data congestion and reduces energy consumption by exploring spatio-temporal correlations among data samples. The adaptive rate-distortion feature balances the compressed data size (data rate) with the required error bound guarantee (distortion level). This compression relieves the strain on energy and bandwidth resources while collecting WSN data within tolerable error margins, thereby increasing the scale of WSNs. The algorithm is evaluated using real-world datasets and compared with conventional methods for temporal and spatial data compression. The experimental validation reveals that the proposed algorithm outperforms several existing WSN data compression methods in terms of compression efficiency and signal reconstruction. Moreover, an energy analysis shows that compressing the data can reduce the energy expenditure, and hence expand the service lifespan by several folds.

Facets of regularization in high-dimensional learning: Cross-validation, risk monotonization, and model complexity
Creators: name: Patil, Pratik
Publisher: name: Carnegie Mellon University
Year: 2022
Subjects: subject: Statistics
subject: FOS: Mathematics

description: This thesis studies aspects of regularization in a high-dimensional regime in which the feature size grows proportionally with the sample size. Several commonly used prediction procedures, such as ridge and lasso, exhibit peculiar risk behavior in this regime: no explicit regularization can be optimal for (random-X) test error, the risk can be non-monotonic in the sample size, and the risk curve can exhibit double or multiple descents in the feature size, treated as a complexity measure. In this thesis, we present results on cross-validation, risk monotonization, and model complexity along these angles. Cross-validation. We show strong uniform consistency of generalized and leave-one-out cross-validation (GCV and LOOCV) for estimating the squared test error of ridge regression. Consequently, we show that ridge tuning via GCV or LOOCV almost surely delivers the optimal regularization, be it positive, negative, or zero. Furthermore, by suitably extending GCV and LOOCV, we construct consistent estimators of the entire test error distribution and a broad class of its linear and nonlinear functionals. Our results require only minimal moment assumptions on the data distribution and are model-agnostic. Risk monotonization. We develop a framework that modifies any generic prediction procedure such that its risk is asymptotically monotonic in the sample size. As part of our framework, we propose two data-driven methodologies, namely zero- and one-step, that are akin to bagging and boosting, respectively, and show that under very mild assumptions they achieve monotonic asymptotic risk behavior. Our results are applicable to a wide class of prediction procedures and loss functions, and do not assume a well-specified model. We exemplify our framework with concrete analyses of the ridgeless and lassoless procedures. Model complexity. We revisit model complexity through the lens of model optimism and degrees of freedom. By re-interpreting degrees of freedom in the fixed-X prediction setting, we extend this concept to the random-X prediction setting. We then define a family of complexity measures, whose two extreme ends we call the emergent and intrinsic degrees of freedom of a prediction model. Through linear and nonlinear example models, we illustrate how the proposed measures may prove useful to align the subtle multiple descents behavior with the typical single descent behavior observed in classical statistical prediction.

description: Data mining algorithms are originally designed by assuming the data is available at one centralized site.These algorithms also assume that the whole data is fit into main memory while running the algorithm. But in today's scenario the data has to be handled is distributed even geographically. Bringing the data into a centralized site is a bottleneck in terms of the bandwidth when compared with the size of the data. In this paper for multiclass SVM we propose an algorithm which builds a global SVM model by merging the local SVMs using a distributed approach(DSVM). And the global SVM will be communicated to each site and made it available for further classification. The experimental analysis has shown promising results with better accuracy when compared with both the centralized and ensemble method. The time complexity is also reduced drastically because of the parallel construction of local SVMs. The experiments are conducted by considering the data sets of size 100s to hundred of 100s which also addresses the issue of scalability.

description: Purpose of Project: This project's purpose was to improve sleep quality in participants with identified difficulty sleeping using lavender essential oil. Aromatherapy has been studied as a complementary approach to the treatment of sleep disorders. The project took place in a primary care office. Methodology: This study used a quasi-experimental design to evaluate the use of daily topical lavender essential oil once nightly for two weeks on sleep quality. Recruitment inclusion criteria included adults over the age of 18, those who spoke English, and those who had complaints of difficulty sleeping. The PSQI scale measures sleep quality and duration using a nine-item questionnaire and was used to assess participant sleep characteristics. The lavender essential oil was distributed to participants and project stakeholders were educated on its use. Demographic data, PSQI data, and an open-ended response was collected via Qualtrics electronic software. Data was exported from Qualtrics and was analyzed using SPSS Software. Results: PSQI data was analyzed using a paired t-test and open-ended question was analyzed for themes. Results on the total PSQI tool, as well as each sub-category showed a mean reduction in scores from pre to post-test scores. In looking at the categories that made up the total score, sleep disturbance, duration, latency, overall sleep quality, and day dysfunction all had a p < .001, showing that the results were significant. Sleep efficiency showed that the results were also significant with a p < .008. The results in the needs medication category were not significant. The reduction in scores proved that lavender essential oil was able to improve the participant’s sleep quality. Implication for Practice: The results of this project improved provider identification of patient sleep disturbances, incorporated lavender into the treatment of insomnia, and provided further research into the use of alternative therapies such as aromatherapy.

description: The E12-10-002 experiment which ran in 2018 in Hall C at the Thomas Jefferson National Accelerator Facility measured the inclusive electron scattering cross-sections for hydrogen and deuterium. This was the first experiment conducted with the new Super High-Momentum Spectrometer and accompanying instrumentation. These measurements extend the previous Hall C measurements up to Q2 = 16 GeV2 . This dissertation presents the analyses of the new detectors and shows the preliminary results for F2 structure function and the study of quark-hadron duality in the four nucleon-resonance regions.

description: If we interpret the Bekenstein-Hawking entropy of the Hubble horizon as thermodynamic entropy, then the entanglement entropy of the superhorizon modes of curvature perturbation entangled with the subhorizon modes will exceed the Bekenstein-Hawking bound at some point; we call this the unitary paradox of cosmological perturbations by analogy with black hole. In order to avoid a fine-tuned problem, the paradox must occur during the inflationary era at the critical time $t_c=\ln(3\sqrtπ/\sqrt{2}ε_HH_{inf})/2H_{inf}$ (in Planck units), where $ε_H= -\dot{H}/H^2$ is the first Hubble slow-roll parameter and $H_{inf}$ is the Hubble rate during inflation. If we instead accept the fine-tuned problem, then the paradox will occur during the dark energy era at the critical time $t_c'=\ln(3\sqrtπH_{inf}/\sqrt{2}fe^{2N}H_Λ^2)/2H_Λ$, where $H_Λ$ is the Hubble rate dominated by dark energy, $N$ is the total number of e-folds of inflation, and $f$ is a purification factor that takes the range $0

On dark matter structure in Milky Way-mass galaxies
Creators: name: Sloane, Jonathan D.
Publisher: name: No Publisher Supplied
Year: 2022

description: A set of four paired cosmological simulations of Milky Way-mass galaxies are used to examine the dark matter structure. Particular attention is paid to the ability of simulated velocity distributions to inform the experimental search for dark matter and the change in dark matter velocity distributions due to the addition of baryons. It is found that the dark matter distributions from hydrodynamic simulations are better described by the Standard Halo Model (which assumes a Maxwellian distribution for dark matter velocities) than dark matter-only simulations. Thus, the additional of baryonic physics to simulations does not alleviate tension in results from dark matter direct detection experiments which generally assume the Standard Halo Model.The dark matter and stellar content of these galaxies is examined in both the virialized and the debris components. Previous works have yielded contradictory results on whether there is a stellar population that could be used observationally to infer the underlying dark matter velocity distributions in the solar neighborhood. The stellar material is not found - in either case - to be a particularly good tracer of dark matter material, especially at the extreme velocities. The diversity in Milky Way mass galaxies shows the need to carefully match the Milky Way in a variety of categories. The specific merger history is found to be important for velocity structures, even for old merger events.

description: The two-point statistics such as the matter power spectrum or the cosmic microwave background (CMB) temperature spectrum in cosmology contain essential information of the universe. This thesis presents an investigation of the physics beyond the standard two-point statistics in both galaxy and CMB surveys. We point out the time delay effect in CMB lensing is not negligible – the last scattering surface is not a perfect sphere, and construct an approach of measuring the distortions in the observed CMB fields. The signal-to-noise ratio of the map is detectable for the dipole moment therefore providing possibilities of observing this effect on the largest scales in future surveys. Next we look into large scale matter density modes which are difficult to be measured directly due to observational systematic effects. We study the approach of measuring the linear density modes by indirectly observing their impact on small scale perturbations. Physically speaking small scale structure will grow faster in a more dense area due to a stronger gravitational potential. We also generalize this method to include galaxy bias, redshift space distortion and light-cone effects to prepare for potential applications in spectroscopic surveys. Finally we establish a deep neural network based on the super resolution technique to reconstruct CMB convergence field using observed polarizations. Next generation CMB surveys are designed to have unprecedented low level of noise, thus the main challenge in the traditional appoaches of CMB lensing reconstruction would be recapturing small scale features. Our generative adversarial network (GAN) targets at reconstructing high resolution maps. We also compare the result with a previous deep learning approach – ResidualUNet.

description: In real-time and high-resolution Earth observation imagery, Low Earth Orbit (LEO) satellites capture images that are subsequently transmitted to ground to create an updated map of an area of interest. Such maps provide valuable information for meteorology or environmental monitoring, but can also be employed in near-real time operation for disaster detection, identification, and management. However, the amount of data generated by these applications can easily exceed the communication capabilities of LEO satellites, leading to congestion and packet dropping. To avoid these problems, the Inter-Satellite Links (ISLs) can be used to distribute the data among the satellites for processing. In this paper, we address an energy minimization problem based on a general satellite mobile edge computing (SMEC) framework for real-time and very-high resolution Earth observation. Our results illustrate that the optimal allocation of data and selection of the compression parameters increase the amount of images that the system can support by a factor of 12 when compared to directly downloading the data. Further, energy savings greater than 11% were observed in a real-life scenario of imaging a volcanic island, while a sensitivity analysis of the image acquisition process demonstrates that potential energy savings can be as high as 92%.
