description: We present a technique to identify the most probable dynamical formation scenario for an observed binary or triple system containing one or more merger products or, alternatively, to rule out the possibility of a dynamical origin. Our method relies on an analytic prescription for energy conservation during stellar encounters. With this, observations of the multiple star system containing the merger product(s) can be used to work backwards in order to constrain the initial orbital energies of any single, binary or triple systems that went into the encounter. The initial semi-major axes of the orbits provide an estimate for the collisional cross section and therefore the time-scale for the encounter to occur in its host cluster. We have applied our analytic prescription to observed binary and triple systems containing blue stragglers, in particular the triple system S1082 in M67 and the period distribution of the blue straggler binaries in NGC 188. We have shown that both S1082 and most of the blue straggler binaries in NGC 188 could have a dynamical origin, and that encounters involving triples could be a significant contributor to BS populations in old open clusters. In general, our results suggest that encounters involving triples could make up a significant fraction of those dynamical interactions that result in stellar mergers, in particular encounters that produce multiple star systems containing one or more blue stragglers.

Assessment of Head and Neck Squamous Cell Carcinomas in Minority Racial/Ethnic Groups in the US
Creators: name: Shaveta Khosla

description: Purpose- The goal of this study was to assess racial/ethnic differences among male head and neck squamous cell carcinoma (HNSCC) cases from minority racial/ethnic groups in the US, with special focus on the three largest Asian diasporas, namely, Chinese, South Asian Indians/Pakistanis (I/P), and Filipinos. The purpose of the first aim was to examine the site group, Human Papillomavirus (HPV) status and temporal trends in male HNSCC cases from minority racial/ethnic groups (i.e., Non-Hispanic Blacks, Hispanics, American Indians, Asians, and Pacific Islanders) and compare them to Non-Hispanic Whites (NHW). As HNSCCs represent the most common cancer in males in parts of Asia, and Asians are the fastest growing minority group in the US, the purpose of second and third aims were to examine differences in temporal trends, site group, late stage diagnosis, all-cause mortality and overall survival in male HNSCC cases from three largest Asian subgroups in the US and compare them to NHW. Methods- Secondary data from National Cancer Database were used. We used multinomial logistic and Cox proportional hazards models. Temporal trends were assessed by calculating annual percentage change. Kaplan Meier survival estimates and log rank tests were used to assess survival differences. Results- Diagnosis at a younger age was much more likely in minority racial/ethnic groups, especially among Asians (overall, and among the three largest Asian subgroups) and Pacific Islanders. In comparison to NHW who were more likely to develop oropharyngeal cancers (OPCs), minority groups were more likely to have HNSCCs of other site groups and had lower likelihood of HPV 16/18 positive OPC. Asians had the highest likelihood of having HNSCCs of other site groups with 11 times higher odds of non-oropharyngeal cancers (Non-OPC) and three times higher odds of oral cavity cancers (OCC). Among Asian diasporas, South Asians had a greater proportion of OCC, while Chinese and Filipinos had a far greater proportion of Non-OPC. South Asian I/P cases doubled from 2004 to 2013 largely due to increase in OCC. Only Chinese had significantly lower odds of late stage diagnosis, compared to NHW but all three Asian subgroups had lower hazards of dying. Conclusion- Significant racial/ethnic differences exist in site group, HPV 16/18 status and survival. Differences in risk factors are potentially contributing to some of these differences. Moreover, younger age at diagnosis among minority groups, in general, and among the Asian diasporas points towards an early initiation of risky habits. There is an urgent need to discourage the initiation and continuation of risky habits and restrict access to the risk factors, such as areca nut, through policy changes. There is a need to also promote screening among specific subpopulations who are at a higher risk of HNSCCs of certain specific sites, such as OCC in South Asians.

description: Ausgehend von Andreas Arndt Buch "Die Reformation der Revolution. Friedrich Schleiermacher in seiner Zeit" wird die Bedeutung der von Schleiermacher konzipierten Dialektik für dessen praktisches Wirken erörtert. Mit der Dialektik stieß er eine Revolutionierung von Mathematik und Logik durch die Gebrüder Graßmann an. Mit seinem Engagement im Rahmen der Humboldtschen Bildungsreform hatte er einen wesentlichen Anteil an der inhaltlichen Neugestaltung der Elementar- und Volksschulbildung. Schleiermachers philosophischer Impuls griff dergestalt - in wohl historisch einmaliger Weise - von der Elementarschulbildung auf die Wissenschaft, insbesondere Mathematik, über.
description: Based on Andreas Arndt's book "Die Reformation der Revolution. Friedrich Schleiermacher in seiner Zeit", the importance of the dialectic conceived by Schleiermacher for his practical work is discussed. With the dialectic he initiated a revolution in mathematics and logic by the Graßmann brothers. With his involvement in the framework of the Humboldt educational reform, he played a major role in the redesign of the content of elementary and primary school education. Schleiermacher's philosophical impulse spread from elementary school education to science, especially mathematics, in what is probably historically unique.

description: An analog of the Meir-Wingreen formula for the steady-state heat current through a model molecular junction is derived. The expression relates the heat current to correlation functions that involve operators only acting on the degrees of freedom of the molecular junction. As a result, the macroscopic heat reservoirs are not treated explicitly. This allows one to exploit methods based on a reduced description of the dynamics of a relatively small part of the overall system to evaluate the heat current through a molecular junction. The derived expression is applied to calculate the steady-state heat current in a weak coupling limit, where Redfield theory is used to describe the reduced dynamics of the molecular junction. The results are compared with those from the previously developed approximate and numerically exact methods.

description: A novel silica-bonded propyl-N-sulfamic acid nanocatalyst (NHSO3H-KIT-5) supported on modified silica mesopore KIT-5 as an organic-inorganic hybrid with high specific surface area was successfully prepared. The 3-aminopropyltriethoxysilane (APTES) on KIT-5 was reacted with chlorosulfonic acid and accurately characterized by the FT-IR, XRD, SEM, EDAXS, and TGA techniques. This heterogeneous and recyclable catalyst catalyzed one pot, multicomponent condensation of benzil, aromatic aldehydes, and ammonium acetate in the presences of 0.05 g of nanocatalyst under solvent-free conditions to afford triaryl-imidazoles in excellent yields. This catalyst showed high catalytic activity under green conditions. This reaction was performed under open air conditions and required no special reaction conditions or chromatographic separation for purification.

description: Magical supergravities are a very special class of supergravity theories whose symmetries and matter content in various dimensions correspond to symmetries and underlying algebraic structures of the remarkable geometries of the Magic Square of Freudenthal, Rozenfeld and Tits. These symmetry groups include the exceptional groups and some of their special subgroups. In this paper, we study the general gaugings of these theories in six dimensions which lead to new couplings between vector and tensor fields. We show that in the absence of hypermultiplet couplings the gauge group is uniquely determined by a maximal set of commuting translations within the isometry group SO(n_T,1) of the tensor multiplet sector. Moreover, we find that in general the gauge algebra allows for central charges that may have nontrivial action on the hypermultiplet scalars. We determine the new minimal couplings, Yukawa couplings and the scalar potential.

TEM of Biologically Induced Reactions: Kidney Stone Mineralization and E. coli-Fiber Interactions
Creators: name: Banner, David J
Publisher: name: University of Illinois at Chicago
Year: 2020
Subjects: Uncategorized

description: The recent development of liquid electron microscopy (EM) has enabled real-time studies of biological and biologically relevant species at the nanoscale. Here, liquid transmission EM (TEM) provides fundamental, mechanistic insight into: 1) the nanoscale interaction of bacteria with antibacterial surface topologies, and 2) into the nanoscale nucleation and dissolution of calcium oxalate (CaOx), which is the major phase of approximately 80% of kidney stones. In contrast to conventional antibiotics or chemical treatments, nanoscale surface roughness can kill bacteria or prevent bacterial binding without the presence of toxic compounds. Rough surface topologies were first etched on biocompatible poly (lactic-glycolic acid) (PLGA) microparticles (MPs). In contrast to previous mathematical models, liquid TEM of E. coli and PLGA MPs revealed that protrusions on the surface of the MPs directly penetrate the bacteria to produce cell lysis. Additionally, the nucleation and formation of CaOx was observed in liquid TEM. CaOx crystallizes via the classical nucleation pathway or via a non-classical multiphase nucleation pathway. The classical nucleation pathway forms rhombohedral CaOx monohydrate (COM), while the non-classical multiphase pathway forms square CaOx (COM). The presence of citrate, a kidney stone inhibitor, alters CaOx nucleation in two ways: first, at low concentrations of CaOx, calcium and citrate form soluble interactions which prevent the nucleation of CaOx. At higher CaOx concentrations, CaOx overcomes the effect of citrate. Citrate instead draws more water molecules into the formed CaOx particle. This increases the hydration state to form dihydrate (COD). Previous studies indicated that COD does not bind to cell walls as well as COM binds to cell walls. Thus, citrate prevents kidney stones by preventing the nucleation of CaOx and by promoting the excretion of COD. Liquid TEM was supported by extensive molecular dynamics (MD) simulations and ex situ benchtop experiments.

description: It has been suggested that multiple scattering on circumstellar dust could explain the non-standard reddening observed in the line-of-sight to Type Ia supernovae. In this work we use Monte Carlo simulations to examine how the scattered light would affect the shape of optical lightcurves and spectral features. We find that the effects on the lightcurve widths, apparent time evolution of color excess and blending of spectral features originating at different photospheric velocities should allow for tests of the circumstellar dust hypothesis on a case by case basis. Our simulations also show that for circumstellar shells with radii r=1e16-1e19 cm, the lightcurve modifications are well described by the empirical Dm_15 parameter and intrinsic color variations of order sigma_{BV}=0.05-0.1 arise naturally. For large shell radii an excess lightcurve tail is expected in B-band, as observed in e.g. SN2006X.

description: The purpose of this article is to show that a $\mathcal{C}^1$ differential system on $\R^n$ which admits a set of $n-1$ independent $\mathcal{C}^2$ conservation laws defined on an open subset $Ω\subseteq \R^n$, is essentially $\mathcal{C}^1$ equivalent on an open and dense subset of $Ω$, with the linear differential system $u^\prime_1=u_1, \ u^\prime_2=u_2,..., \ u^\prime_n=u_n$. The main results are illustrated in the case of two concrete dynamical systems, namely the three dimensional Lotka-Volterra system, and respectively the Euler equations from the free rigid body dynamics.

Bad Jobs or ‘Badass’ Jobs? Fishing Guides, Self-Employment, and Service Work in the New Economy

description: In an era of polarizing job quality, where uncertainty and precarity are the new normal of the labor market, interactive service work is oft regarded as a ‘bad’ job and feminine-coded. How might it be, then, that some forms of insecure service work are considered ideal and even masculine? In this dissertation, I use the case of for-hire captains specializing in fishing tourism services—i.e. “fishing guides”—to highlight the interactional and organizational dynamics that allow and constrain the masculinization of service work. Drawing on interviews with seventy captains and six other stakeholders, I find that the self-employed leverage their independent employment relation to avoid traditional emotional labor and sort out clients who do not allow them to experience their work as authentic, masculine, and ‘badass.’ But in doing so, these men shift from selling a service to selling the self—a move that makes them more personally vulnerable, engaging in unpaid labor to maintain relationships with elite clientele. Beyond their agentic efforts, I reveal the shifting organizational terrain of a tourism-driven economy that underlies and threatens old business models and the marine environment in which guides labor. These findings shed light on the possibilities and limits of power, autonomy, and masculinities in contemporary interactive service industries and non-standard employment relations.

ISIS threat to India : how should India respond?

description: This thesis traces the evolution of the Islamic State of Iraq and Syria (ISIS) and its present geopolitical extent and identifies the major trends and strategic directions. It examines the official pronouncements about its intentions regarding India and analyses the threat and proposes a policy prescription. Today’s terrorist organizations, including ISIS, publish online magazines and videos stating their policies, strategies and, tactics. These original voices were studied to understand them. The US invasion of Iraq (2003) and the subsequent failure in creating a “democratic government” acceptable to the powerful Sunni minority led to strife and sectarian violence. Radical Islamists and leftover elements of Saddam Hussain’s military got together and created large scale insurgency eventually leading to the declaration of a “Caliphate” calling out to all the Muslims in the world to accept it and join the effort to extend it. Less than 30 Indians as compared to a total of 25,000 are known to have migrated to ISIS area. Even with all its aberrations, India’s resilience as a syncretic and inclusive society renders hijrat (migration) an unattractive option. But coming together of radicalized youth into a small terror modules and striking nearer home is a real and probable threat. To protect itself, India should follow policies that integrate its Muslim community into the social mainstream. To prevent its people from getting radicalized through exposure to ISIS propaganda, the counter radicalization effort needs to be strengthened. The few persons who are known to have been radicalized but have not undertaken any kind of violence could be considered for softer deradicalization methods. By involving their family, friends and, community it is possible to bring these people back into normal domestic life. Attacks can still happen and the capability to deal with them must be enhanced by creating interdiction capabilities at the state and district levels. Finally, international terror requires measures across countries for which mechanisms for international cooperation must be created so that information, intelligence and, evidence flow seamlessly.
Computational Modeling to Predict and Affect Recovery After Stroke

description: There is currently no direct association between patient movement kinematics and rehabilitation outcomes for stroke survivors. Research has demonstrated minor successes in predicting some clinical measures. Recent advancements in machine learning algorithms and robotic technology enable us to parse through a large amount of patient movement data to find appropriate targets for treatment. This thesis examines the predictability of chronic stroke survivor clinical outcomes following neurological injury using patient movement and demographic data, and whether predictive movement metrics can be influenced to improve recovery. Building on a recent two-week study with stroke survivors, we construct a machine learning model to predict clinical changes, and use the model to determine an appropriate intervention target. We then establish how this target should be altered in a crossover trial with chronic stroke survivors. Lastly, we test a two-week treatment in a chronic stroke survivor case study. Our predictive models determined that movement speed was a proper focus for an intervention. In our crossover trial, we showed that negative viscosity had the strongest effect on movement speed. Treating a patient with negative viscosity for two weeks showed significant improvements in multiple movement metrics, and small gains in clinical outcomes. These results show that designing a rehabilitation intervention based on negative viscosity can lead to improvements in chronic stroke survivors. Our success also establishes the framework we used for this patient population as a potentially generalizable pipeline to identify and test interventions for other populations. Further research could focus on testing treatments for some of the other model predictors, as they could present more potential intervention targets.

description: We obtain a representation formula for the derivative of the spectral shift function $ξ(λ; B, ε)$ related to the operators $H_0(B,ε) = (D_x - By)^2 + D_y^2 + εx$ and $H(B, ε) = H_0(B, ε) + V(x,y), \: B > 0, ε> 0$. We prove that the operator $H(B, ε)$ has at most a finite number of embedded eigenvalues on $\R$ which is a step to the proof of the conjecture of absence of embedded eigenvalues of $H$ in $\R.$ Applying the formula for $ξ'(λ, B, ε)$, we obtain a semiclassical asymptotics of the spectral shift function related to the operators $H_0(h) = (hD_x - By)^2 + h^2D_y^2 + εx$ and $H(h) = H_0(h) + V(x,y).$
Political Connections, Macroeconomic Stimulus, and Firm Performance: Evidence from China

Publisher: name: University of Illinois at Chicago
Year: 2020
Subjects: Uncategorized

description: Gaining knowledge of the link between political connections and firm behavior is important for a general understanding of how resource allocation is affected by political connections. This dissertation will examine this link by using the difference-in-difference model and panel vector autoregression model with data about all the listed companies on China’s two stock markets (Shanghai and Shenzhen) from 2003 to 2012. The first chapter will introduce China’s political system, political connections between the government and listed companies, and the potential impact on firm performance. The second chapter explores the impact of China’s stimulus package on firm behavior through political connections. In response to the global financial crisis of 2008, China launched its “four trillion-yuan stimulus package”. Companies with close relationships to the central and local governments were likely to benefit more from this stimulus package. Chapter 2 uses a difference-in-difference analysis to compare politically connected and nonpolitically connected firms before and after 2008. The empirical results suggest that after the adoption of the stimulus package, politically connected firms had about 7.1% higher leverage, 9.3% higher receivables, and 6.6% lower sales compared to firms lacking those political connections, while the levels of investment, cash stock, and profit among all these firms were not significantly different. The last chapter uses within-firm variations to detect the impact of political connections on firm behavior. Using a panel vector autoregression model yields findings that show a positive shock in political connections has positive impacts on profit, receivables, and cash, while resulting in negative impacts on leverage, investment, and sales. These results suggest that a firm might need to strengthen its connections, and thus bring advantages to the organization, by hiring board members who used to be government officials. However, when a firm has already established its political connections with the government, it might need to seriously consider whether to forge more connections since there are both advantages and disadvantages to increasing political connections within a firm. For an economy, building up political connections likely harms resource allocation and long-term economic growth because the resources the firms spend on hiring previous government officials and the resources allocated to the politically connected firms are all considered to be misallocated.

description: We present calculations of expected continuum emissions from Sedov-Taylor phase Type Ia supernova remnants (SNRs), using the energy spectra of cosmic ray (CR) electrons and protons from nonlinear diffusive shock acceleration (DSA) simulations. A new, general-purpose radiative process code, Cosmicp, was employed to calculate the radiation expected from CR electrons and protons and their secondary products. These radio, X-ray and gamma-ray emissions are generally consistent with current observations of Type Ia SNRs. The emissions from electrons in these models dominate the radio through X-ray bands. Decays of π^0 s from p-p collisions mostly dominate the gamma-ray range, although for a hot, low density ISM case (n_{ISM}=0.003 cm^{-3}), the pion decay contribution is reduced sufficiently to reveal the inverse Compton contribution to TeV gamma-rays. In addition, we present simple scalings for the contributing emission processes to allow a crude exploration of model parameter space, enabling these results to be used more broadly. We also discuss the radial surface brightness profiles expected for these model SNRs in the X-ray and gamma-ray bands.

As an application, we describe hamiltonian flows as special symplectic micromorphisms whose local generating functions are the solutions of Hamilton-Jacobi equations. We obtain a purely categorical formulation of the temporal evolution in classical mechanics.

description: The domestic rabbit (Oryctolagus cunniculus), continues to lag behind in terms of genetically inclined research necessary for its characterization in Nigeria, hence this study, which investigated the genetic characterization and bottleneck analysis of rabbit populations in Nigeria using microsatellite markers.The Bottleneck analysis sought to determine recent bottleneck (heterozygosity excess) in rabbit populations. The analysis revealed the heterozygosity excess values obtained were non-significant (P > 0.05) warranting the rejection of the null hypothesis that suggested a genetic bottleneck in the rabbit populations.The findings showed that there were high levels of genetic disparity among the commonest breeds of Rabbits adapted to Nigeria, which encourages further genetically inclined research to facilitate the identification and development of effective breeding strategies crucial for the preservation and conservation of this animal genetic resource in Nigeria.

description: Among all electromagnetic theories which (a) are derivable from a Lagrangian, (b) satisfy the dominant energy condition, and (c) in the weak field limit coincide with classical linear electromagnetics, we identify a certain subclass with the property that the corresponding static, spherically symmetric, asymptotically flat electrovacuum spacetime metric has the mildest possible singularity at its center, namely, a conical singularity on the time axis. The electric field moreover has a point defect on the time axis, its total energy is finite, and is equal to the ADM mass of the spacetime. By an appropriate scaling of the Lagrangian, one can arrange the total mass and total charge of these spacetimes to have any chosen values. For small enough mass-to-charge ratio, these spacetimes have no horizons and no trapped null geodesics. We prove the uniqueness of these solutions in the spherically symmetric class. We conclude by performing a qualitative study of the geodesics and test-charge trajectories of these spacetimes.

description: Proving the chaoticity of some dynamical systems is equivalent to solving the hardest problems in mathematics. Conversely, one argues that it is not unconceivable that classical physical systems may "compute the hard or even the incomputable" by measuring observables which correspond to computationally hard or even incomputable problems.

Exploring the principle of provenance with social network analysis
Creators: name: Chandler, Kathryn Suzanne
Publisher: name: University of British Columbia

description: Traditionally, an archival fonds is conceptualized as an aggregate of records which are mutually relevant. This mutual relevance is often attributed to the origin of member records in a common context – with this context typically understood as the context of an organization, and more specifically, a department. It is considered difficult to identify mutually relevant records in modern organizations. This difficulty is often attributed to frequent administrative changes which disrupt departmental contexts. This thesis tests a technique that aims to use the information within the records to identify a context common to a set of records. It involves extracting the name of the creator and the name of the modifier from each record, then subjecting this information to a community detection algorithm. It was hypothesized that groups of individuals who frequently modify one another’s records constitute a common context. After applying various community detection algorithms to the records of an organization, the resulting groups of records were presented to the staff of the organization for feedback. Staff clearly indicated that groups of records produced by the community detection algorithms were not mutually relevant. These results can be explained with reference to the works of Jenny Bunn, who argued that an autonomous community only comes into existence when constituent members engage in both “being” and “doing.” During the interviews with staff, it was clear that some algorithms produced groups of people characterized by established relationships (“being”) while others produced groups in pursuit of a joint activity (“doing”). The absence of overlap suggests there were no autonomous subcommunities in this study, and therefore, no common context by which records can be bound. Mutually relevant records can also be formed by employees in their attempts to keep records orderly. To explore this further, it was argued that constructing a folder structure is akin to constructing a narrative, with the narrative components taking the form of records. When numerous employees attempt to organize the same records using different narratives, the aggregate may seem disorderly. This thesis suggests that disentangling these narratives is a method by which order may be restored.

description: Intra-lot and inter-lot variability in the spectra of micafungin was detected in the Drug Quality Study (DQS) using Fourier transform near-infrared spectrometry (FTNIR). Two vials of 6 vials sampled from Fresenius Kabi lot ACP106 appeared 7.9 and 14.0 standard deviations (SDs) from the center of the rest of the vials on the DQS FTNIR screening assay. Spectra of 48 vials from 7 lots in the library showed 2 outliers at 8.3 and 9.8 SDs from the center of the rest of the library, suggesting they represent different material.
Quality control is important in drug manufacturing. Good drugs lead to good patient outcomes. These FTNIR results do not prove an excess level of impurities or adulteration. However, they suggest that the manufacturing process may have been operating outside of a state of process control. Additional investigation is needed.

description: Mantidactylus biporus clade
A species-rich, diverse and probably not monophyletic group, containing species characterized by a mostly rather small body size (20.5–35.8 mm adult SVL), short and rounded snout, and typically stout body shape with short hindlimbs. Species in this group often have scattered white spots, especially on flanks and laterally on the head. Contains: M. biporus and five new species, described based on holotypes depicted in Fig. 62. Note that several other species previously thought to be related to M. biporus (or reported to be morphologically similar), are assigned to the M. ulcerosus clade (M. schulzi and M. steinfartzi; see above), and to the M. inaudax and M. stelliger clades (see respective accounts below). One of the new species named in the following (M. bletzae sp. nov.) is not included in the phylogenomic tree, and its relationships are not reliably resolved in the 16S tree. We here assign it tentatively to the M. biporus clade, but it might also be related to the M. inaudax clade.

description: This thesis focuses on the study of heat effects upon electrode reactions with submonolayer conversions. These give information about the entropy change at the electrode/electrolyte interface. The employed calorimeter allowed the detection of temperature changes upon the conversion of a few nanomols per cm² electrode surface. Calorimetric studies were performed for various metal deposition processes from copper and silver containing electrolytes, and for hydrogen adsorption on platinum.

description: Band structure trends in hole-doped cuprates and correlations with T_c are interpreted within the s--d exchange mechanism of high-T_c superconductivity. The dependence of T_c on the position of the copper 4s level finds a natural explanation in the generic Cu 3d, Cu 4s, O 2p_x and O 2p_y four-band model. The Cu 3d--Cu 4s intra-atomic exchange interaction is incorporated in the standard BCS scheme. This dependence of T_c in the whole interval of 25--125 K has no alternative explanation at present, and possibly this quarter of a century standing puzzle is already solved.

description: We clarify that the antiferromagnetic order in the distorted tetrahedral quasi-one dimensional spin system induces electric polarizations. In this system, the effects of the low dimensionality and the magnetic frustration are expected to appear simultaneously. We obtain the magnetic-field-temperature phase diagram in Cu3Mo2O9 by studying the dielectric constant and the spontaneous electric polarization. Around the tricritical point at 10 T and 8 K, the change of the direction in the electric polarization causes a colossal magnetocapacitance. We calculate the charge redistribution in the small spin cluster consisting of two magnetic tetrahedra to demonstrate the electric polarization induced by the antiferromagnetism.
