description: Massive star-forming galaxies in the high-redshift universe host large reservoirs of cold gas in their circumgalactic medium (CGM). Traditionally, these reservoirs have been linked to diffuse H I Lyman-$α$ (Ly$α)$ emission extending beyond $\approx 10$ kpc scales. In recent years, millimeter/submillimeter observations are starting to identify even colder gas in the CGM through molecular and/or atomic tracers such as the [C II] $158\,μ$m transition. In this context, we study the well-known J1000+0234 system at $z=4.54$ that hosts a massive dusty star-forming galaxy (DSFG), a UV-bright companion, and a Ly$α$ blob. We combine new ALMA [C II] line observations taken by the CRISTAL survey with data from previous programs targeting the J1000+0234 system, and achieve a deep view into a DSFG and its rich environment at a 0.2" resolution. We identify an elongated [C II]-emitting structure with a projected size of 15 kpc stemming from the bright DSFG at the center of the field, with no clear counterpart at any other wavelength. The plume is oriented $\approx 40^{\circ}$ away from the minor axis of the DSFG, and shows significant spatial variation of its spectral parameters. In particular, the [C II] emission shifts from 180 km/s to 400 km/s between the bottom and top of the plume, relative to the DSFG's systemic velocity. At the same time, the line width starts at 400-600 km/s but narrows down to 190 km/s at top end of the plume. We discuss four possible scenarios to interpret the [C II] plume: a conical outflow, a cold accretion stream, ram pressure stripping, and gravitational interactions. While we cannot strongly rule out any of these with the available data, we disfavor the ram pressure stripping scenario due to the requirement of special hydrodynamic conditions.

Remarks. Occurrence in Clay County, Minnesota, across the Red River from Cass County, North Dakota, confirms the record from Fargo. The northernmost localities in central North America, they are approximately 224 km (140 mi) south of the International Border, so in Canada, P. flavipes may inhabit southeastern Manitoba as well as Essex County, Ontario (Shelley 1988, 2002c). Shelley et al. (2003) predicted that P. flavipes surely occurs in the eastern periphery of South Dakota, along the Missouri and Big Sioux rivers, and the Lincoln Co. site confirms this prediction. The Day Co. locality is slightly west of I-29 and intermediate between Fargo and Lincoln Co. Published illustrations are available in Shelley (1978 [as Pleuroloma sp.], 1980, 1988)

description: The complexity of a system description is a function of the entropy of its symbolic description. Prior to computing the entropy of the system description, an observation scale has to be assumed. In natural language texts, typical scales are binary, characters, and words. However, considering languages as structures built around certain preconceived set of symbols, like words or characters, is only a presumption. This study depicts the notion of the Description Fundamental Scale as a set of symbols which serves to analyze the essence a language structure. The concept of Fundamental Scale is tested using English and MIDI music texts by means of an algorithm developed to search for a set of symbols, which minimizes the system observed entropy, and therefore best expresses the fundamental scale of the language employed. Test results show that it is possible to find the Fundamental Scale of some languages. The concept of Fundamental Scale, and the method for its determination, emerges as an interesting tool to facilitate the study of languages and complex systems.

description: This thesis focuses on poet and publisher d.a.levy’s Cleveland undercovers, clearing ground for further research on his biography and publishing practices as well as comparative analysis with other poets. Before analyzing his long poem Cleveland undercovers, I will first share a biography and confront misconceptions of his life and work. Following my introduction, I will briefly review commentary on levy’s concrete poetry, Buddhism, and anti-capitalist revolutionary politics. From this discussion and my exploration of Cleveland undercovers, I will argue that levy’s concrete poetry and revolutionary orientation developed from his Buddhist perspectives and practices. Reflecting on further research to pursue, I will express the value in gathering the fragments of levy’s shattered biography; consider his relationship with other North American Buddhist poets; and emphasize the relevancy of his publishing practices for small presses today.

description: The total fertility rate (TFR) of South Korea was 2.82 in 1980 and, since then it had decreased continuously. It worsened after experiencing the financial crisis in 1997. As a result, TFR recorded 1.076, the lowest level among OECD countries, in 2005. Moreover, the fast decline of TFR makes it hard to find a suitable solution to raise TFR. So the central and local governments established various childbirth encouragement policies, but they have not showed satisfying results. Therefore, to find more fundamental factors which affect TFR, this study analyzes ‘necessity of having children.’ The data used is 297 married women in Cheongdo-gun, which has the lowest TFR compared with other rural areas, and the data is classified as the employed and the non-employed. The results show that the owner of house (+), amount of assets (+), and household income (-) have statistically significant effect on the necessity of having children in the employed, but only household income (-) is so in the non-employed.

description: Future research studies of cosmic microwave background polarization seems likely to provide a more improved upper bound of $r \le 0.03$ on the tensor-to-scalar ratio(r). In our work, we have done the reheating study of mutated hilltop inflation(MHI), a model falling in the broad category of small field inflation. We have parameterized reheating in terms of various parameters like reheating duration $N_{\text{rh}}$, reheating temperature $T_{\text{rh}}$ and effective equation of state $\overline{ω}_{\text{rh}}$ using observationally viable values of scalar power spectrum amplitude $A_{\text{s}}$ and scalar spectral index $n_{\text{s}}$. In our study, working over a range of $\overline{ω}_{\text{rh}}$, we found that the MHI potential is well consistent with combined Planck and BK18 observations for $\overline{ω}_{\text{rh}} > 0$ within a particular range of model's parameter space and the lower values of the model parameter in MHI generate considerably smaller r compared to normal hilltop potential without any incompatibility of $n_s$ with observational data, making MHI a better choice in accordance to recent and future studies.

Photoassociation of Universal Efimov Trimers

description: In view of recent experiments in ultracold atomic systems, the photoassociation of Efimov trimers, composed of three identical bosons, is studied utilizing the multipole expansion. We study both the normal hierarchy case, where one-body current is dominant, and the strong hierarchy case, relevant for photoassociation in ultracold atoms, where two-body current is dominant. For identical particles in the normal hierarchy case, the leading contribution comes from the r^2 s-mode operator and from the quadrupole d-mode operator. The s-mode reaction is found to be dominant at low temperature, while as the temperature increases the d-mode becomes as significant. For the strong hierarchy case, the leading contribution comes from a 2-body s-wave δ operator. In both cases log periodic oscillations are found in the cross section. For large but finite scattering length the amplitude of the oscillations becomes larger in comparison to infinite scattering length case. We apply our theory to photoassociation of 7Li ultracold atoms and show a good fit to the available experimental results.
Testing Model Atmospheres for Young Very Low Mass Stars and Brown Dwarfs in the Infrared: Evidence for Significantly Underestimated Dust Opacities

Year: 2014

description: We test state-of-the-art model atmospheres for young very low-mass stars and brown dwarfs in the infrared, by comparing the predicted synthetic photometry over 1.2-24 μm to the observed photometry of M-type spectral templates in star-forming regions. We find that (1) in both early and late young M types, the model atmospheres imply effective temperatures (Teff) several hundred Kelvin lower than predicted by the standard Pre-Main Sequence spectral type-Teff conversion scale (based on theoretical evolutionary models). It is only in the mid-M types that the two temperature estimates agree. (2) The Teff discrepancy in the early M types (corresponding to stellar masses above 0.4 Msol at ages of a few Myr) probably arises from remaining uncertainties in the treatment of atmospheric convection within the atmospheric models, whereas in the late M types it is likely due to an underestimation of dust opacity. (3) The empirical and model-atmosphere J-band bolometric corrections are both roughly flat, and similar to each other, over the M-type Teff range. Thus the model atmospheres yield reasonably accurate bolometric luminosities (Lbol), but lead to underestimations of mass and age relative to evolutionary expectations (especially in the late M types) due to lower Teff. We demonstrate this for a large sample of young Cha I and Taurus sources. (4) The trends in the atmospheric model J-K colors, and their deviations from the data, are similar at Pre-Main Sequence and Main Sequence ages, suggesting that the model dust opacity errors we postulate here for young ages also apply at field ages.

description: The Luttinger model is a paradigm for the breakdown due to interactions of the Fermi liquid description of one-dimensional massless Dirac fermions. Attempts to discretize the model on a one-dimensional lattice have failed to reproduce the established bosonization results, because of the fermion-doubling obstruction: A local and symmetry-preserving discretization of the Hamiltonian introduces a spurious second species of low-energy excitations, while a nonlocal discretization opens a single-particle gap at the Dirac point. Here we show how to work around this obstruction, by discretizing both space and time to obtain a \textit{local} Lagrangian for a helical Luttinger liquid with Hubbard interaction. The approach enables quantum Monte Carlo simulations that preserve the topological protection of an unpaired Dirac cone.

description: We extend the definition of hopfions to include a class of spin-$h$ fields and use this to introduce the electromagnetic and gravitational hopfions of different algebraic types. The fields are constructed through the Penrose contour integral transform, thus the singularities of the generating functions are directly related to the geometry of the resulting physical fields. We discuss this relationship and how the topological structure of the fields is related to the Robinson congruence. Since the topology appears in the lines of force for both electromagnetism and gravity, the gravito-electromagnetic formalism is used to analyze the gravitational hopfions and describe the time evolution of their tendex and vortex lines. The correspondence between fields of different spin results in analogous configurations based on the same topological structure. The null and type N fields propagate at the speed of light, while the non-null and type D fields radiate energy outward from the center. Finally we discuss the type III gravitational hopfion, which has no direct electromagnetic analog, but find that it still exhibits some of the characteristic features common to the other hopfion fields.

Proteomic characterization of mammary tumor, adipose tissue, and serum-derived extracellular vesicles

description: My honors thesis details the background, methods, analysis, and discussion of my project investigating the proteomic content of extracellular vesicles that we isolated from serum, mammary tumor, and visceral adipose tissue samples that came from mice with triple negative breast cancer and with and without obesity. This analysis is part of a larger ongoing proteomic analysis where we are investigating differential expression of proteins controlled by diet and tumor size. Our primary findings were that we were able to successfully extract extracellular vesicles from tumor, adipose tissue, and serum. The global proteomic data demonstrated that our EVs contained biomarkers and literature EV proteins, suggesting that the particles that we isolated were, in fact, extracellular vesicles. We found that, broadly speaking, the proteins in tumor and VAT EVs were similar but serum proteins were quite different. This may be because serum EVs were isolated using a different protocol. We chose to focus on pyruvate carboxylase as an important metabolic enzyme and an enzyme that is involved in cancer growth and metastasis. We found pyruvate carboxylase to be present in tumor and VAT EVs, but not in serum EVs. We found pyruvate carboxylase regulators acetyl-CoA and AT-1 in tumor, VAT, and serum EVs.

description: Machine learned potentials (MLPs) have been widely employed in molecular dynamics (MD) simulations to study thermal transport. However, literature results indicate that MLPs generally underestimate the lattice thermal conductivity (LTC) of typical solids. Here, we quantitatively analyze this underestimation in the context of the neuroevolution potential (NEP), which is a representative MLP that balances efficiency and accuracy. Taking crystalline silicon, GaAs, graphene, and PbTe as examples, we reveal that the fitting errors in the machine-learned forces against the reference ones are responsible for the underestimated LTC as they constitute external perturbations to the interatomic forces. Since the force errors of a NEP model and the random forces in the Langevin thermostat both follow a Gaussian distribution, we propose an approach to correcting the LTC by intentionally introducing different levels of force noises via the Langevin thermostat and then extrapolating to the limit of zero force error. Excellent agreement with experiments is obtained by using this correction for all the prototypical materials over a wide range of temperatures. Based on spectral analyses, we find that the LTC underestimation mainly arises from increased phonon scatterings in the low-frequency region caused by the random force errors.
Balancing Platforms: How U.S. Senate Candidates Campaign Across Twitter, Facebook, and Instagram

description: The aim of this study is to identify and compare the patterns of United States Senate candidates’ campaigns on Facebook, Twitter, and Instagram during the 2022 United States Senate Midterm election. While research on political messaging on social media is vast, most of it is confined to a single platform, usually Twitter, and uses programming languages to code social media posts. This work is designed to fill these gaps in the literature by manually performing a cross-platform analysis. I do this by coding a post’s tone and content as it is related to policy issues and other non-policy related topics. Using my own data, my findings support that Senate candidates use different campaign strategies across social media platforms. Specifically, I find that on Twitter, candidates relay more information about themselves and their opponent while using Instagram to serve other campaign functions. I also find that candidates discuss more policy issues on Twitter and discuss these issues to a greater extent when compared to Instagram and Facebook. In addition, I find that in general candidates post a substantial number of non-political posts showcase themselves in their community across all platforms.

description: This paper intends to focus on Cairo streets from the pedestrian-use perspective. It aims to explore and examine the factors that make Cairo streets better places for walking. Moreover, it intends to contribute to the limited qualitative research on walkable streets and pedestrians' walking experience, specifically in Cairo. In addition, it provides a conceptual framework for understanding the walkability of streets and the experience of pedestrians, built on both empirical field study and prevailing theoretical models reviewed in the literature. To closely examine the factors that determine Cairo streets to be walkable and therefore pedestrian-friendly, the research investigates the status of two streets in Cairo as a case study. The case studies section investigated the street characteristics and the local pedestrians' needs and perceptions towards their walking experience in the streets. This study investigated the status of Cairo streets by recording the users' perceptions of different types to understand the causes of this problem. Moreover, to encourage the walking in Cairo streets and promote social activities, the study investigates two major streets in Cairo, "El-Korba and Al-Azhar," using qualitative research methods of participant interviews and observational surveys. Furthermore, it conducted a comparative study to examine the causes and proposals' solutions, down to the study's results.

description: PURPOSE: To determine if the spatial pattern of gonorrhea observed for North Carolina was influenced by neighborhood-level sociocultural determinants of health, including race/ethnicity.

METHODS: A generalized linear mixed model with spatially correlated random effects was fit to measure the influence of socio-cultural factors on the spatial pattern of gonorrhea reported to the North Carolina State Health Department (January 1, 2005 to March 31, 2008).

RESULTS: Neighborhood gonorrhea rates increased as the percent single mothers increased (25th to 75th neighborhood percentile Relative Rate 1.18, 95% CI 1.12, 1.25), and decreased as socioeconomic status increased (Relative Rate 0.89, 95% CI 0.84, 0.95). Increasing numbers of men in neighborhoods with more women than men did not change the gonorrhea rate, but was associated with decreased rates in neighborhoods with more men than women. Living in the mountains was protective for all race/ethnicities. Rurality was associated with decreased rates for Blacks and increased rates for Native Americans outside the mountains.

PURPOSE: Neighborhood-level sociocultural factors, primarily those indicative of neighborhood deprivation, explained a significant proportion of the spatial pattern of gonorrhea in both urban and rural communities. Race/ethnicity was an important proxy for social and cultural factors not captured by measures of socioeconomic status.

description: The purpose of this study was to investigate the perceptions and evaluations of experts on Korea’s forest ODA to draw policy implications for raising the development effectiveness. For this, 25 experts from an ODA implementing agency and 49 forestry experts were selected. The awareness on Korea’s forest ODA, the appropriateness of project objectives, the evaluation on project outcomes and key factors for the successful project implementation were surveyed. In particular, four criteria including relevance, efficiency, effectiveness and impact were selected from OECD DAC evaluation principles for project evaluation. With regard to the relevance of projects, both groups considered feasibility studies had been inadequately conducted and the budget and timeline assigned at the project design stage were not enough. Furthermore, from the result of the study, it can be drawn that Korea’s forest ODA should put more emphasis on poverty eradication and income-boosting activities to contribute to the socioeconomic development in partner countries.

description: The pseudomode framework provides an exact description of the dynamics of an open quantum system coupled to a non-Markovian environment. Using this framework, the influence of the environment on the system is studied in an equivalent model, where the open system is coupled to a finite number of unphysical pseudomodes that follow a time-local master equation. Building on the insight that this master equation does not need to conserve the hermiticity of the pseudomode state, we here ask for the most general conditions on the master equation that guarantee the correct reproduction of the system's original dynamics. We demonstrate that our generalized approach decreases the number of pseudomodes that are required to model, for example, underdamped environments at finite temperature. We also provide an unraveling of the master equation into quantum jump trajectories of non-Hermitian states, which further facilitates the utilization of the pseudomode technique for numerical calculations by enabling the use of easily parallelizable Monte Carlo simulations. Finally, we show that pseudomodes, despite their unphysical nature, provide a natural picture in which physical processes, such as the creation of system-bath correlations or the exchange of heat, can be studied. Hence, our results pave the way for future investigations of the system-environment interaction leading to a better understanding of open quantum systems far from the Markovian weak-coupling limit.

description: Unraveling the interplay between connectivity and spatio-temporal dynamics in neuronal networks is a key step to advance our understanding of neuronal information processing. Here we investigate how particular features of network connectivity underpin the propensity of neural networks to generate slow-switching assembly (SSA) dynamics, i.e., sustained epochs of increased firing within assemblies of neurons which transition slowly between different assemblies throughout the network. We show that the emergence of SSA activity is linked to spectral properties of the asymmetric synaptic weight matrix. In particular, the leading eigenvalues that dictate the slow dynamics exhibit a gap with respect to the bulk of the spectrum, and the associated Schur vectors exhibit a measure of block-localization on groups of neurons, thus resulting in coherent dynamical activity on those groups. Through simple rate models, we gain analytical understanding of the origin and importance of the spectral gap, and use these insights to develop new network topologies with alternative connectivity paradigms which also display SSA activity. Specifically, SSA dynamics involving excitatory and inhibitory neurons can be achieved by modifying the connectivity patterns between both types of neurons. We also show that SSA activity can occur at multiple timescales reflecting a hierarchy in the connectivity, and demonstrate the emergence of SSA in small-world like networks. Our work provides a step towards understanding how network structure (uncovered through advancements in neuroanatomy and connectomics) can impact on spatio-temporal neural activity and constrain the resulting dynamics.

description: Symbolic Computation algorithms and their implementation in computer algebra systems often contain choices which do not affect the correctness of the output but can significantly impact the resources required: such choices can benefit from having them made separately for each problem via a machine learning model. This study reports lessons on such use of machine learning in symbolic computation, in particular on the importance of analysing datasets prior to machine learning and on the different machine learning paradigms that may be utilised. We present results for a particular case study, the selection of variable ordering for cylindrical algebraic decomposition, but expect that the lessons learned are applicable to other decisions in symbolic computation.
 We utilise an existing dataset of examples derived from applications which was found to be imbalanced with respect to the variable ordering decision. We introduce an augmentation technique for polynomial systems problems that allows us to balance and further augment the dataset, improving the machine learning results by 28\% and 38\% on average, respectively. We then demonstrate how the existing machine learning methodology used for the problem $-$ classification $-$ might be recast into the regression paradigm. While this does not have a radical change on the performance, it does widen the scope in which the methodology can be applied to make choices.
Antenna mechanism of length control of actin cables

description: Actin cables are linear cytoskeletal structures that serve as tracks for myosin-based intracellular transport of vesicles and organelles in both yeast and mammalian cells. In a yeast cell undergoing budding, cables are in constant dynamic turnover yet some cables grow from the bud neck toward the back of the mother cell until their length roughly equals the diameter of the mother cell. This raises the question: how is the length of these cables controlled? Here we describe a novel molecular mechanism for cable length control inspired by recent experimental observations in cells. This antenna mechanism involves three key proteins: formins, which polymerize actin, Smy1 proteins, which bind formins and inhibit actin polymerization, and myosin motors, which deliver Smy1 to formins, leading to a length-dependent actin polymerization rate. We compute the probability distribution of cable lengths as a function of several experimentally tuneable parameters such as the formin-binding affinity of Smy1 and the concentration of myosin motors delivering Smy1. These results provide testable predictions of the antenna mechanism of actin-cable length control.
