description: The trans-Planckian censorship conjecture (TCC) puts an upper bound on the life-time of de Sitter spacetimes. It has immediate consequences for inflationary cosmology. In the standard paradigm, the universe has experienced a single stage of inflation and follows a thermal history. Then, the TCC puts an upper bound on the Hubble parameter during inflation $H_{\rm inf}$ around $0.1$ GeV. Consequently, it implies a severe fine-tuning in initial condition for inflation and non-detection of primordial gravitational waves. In this note, we study non-standard cosmological paradigms with non-thermal history and/or multiple stages of inflations. It is motivated by string theory compactifications and axiverse scenarios in which the modulus/axion fields are effective in the early universe. In early matter domination the TCC bound on $H_{\rm inf}$ can be raised up to 3 orders of magnitude. In multiple inflationary scenarios the upper bound on the observable inflation can be raised up $10^{14}$ GeV to touch the Planck 2018 bound.

description: We discuss the QCD constraints on e+e- --> baryon-anti-baryon close to threshold, in light of the puzzling experimental data which indicate that close to threshold sigma (e+e- --> n n-bar) > sigma (e+e- --> p p-bar). We focus on the process e+e- --> Delta Delta-bar, which is particularly simple from the theoretical point of view. In this case it is possible to make exact QCD predictions for the relative yields of the four members of the Delta multiplet, modulo one crucial dynamical assumption.

description: With the large-scale use of pesticides, food safety issues caused by their residues have been drawn increasing concern. In this study, surface-enhanced Raman spectroscopy (SERS) coupled with a Au@Ag nanoparticle (NP)-graphene oxide (GO) composite substrate which was synthesized by a simple self-assembly method was applied for the rapid determination of thiram residues in fruit juice. To obtain high SERS activity, the loading and the aggregation of Au@Ag NP on the graphene oxide sheets were adjusted by controlling the size of Au@Ag nanoparticle and the concentration of graphene oxide in solution. Using the optimal conditions, the limit of detection for thiram standard solution was 6.3 ng/mL, while the limits of detection for thiram in apple juice and grape juice without any pretreatment were 36.7 and 134.4 ng/mL, respectively. The entire analytical process required less than 20 min. The results indicated that SERS technology coupled with Au@Ag nanoparticle graphene oxide composite substrate was a simple, rapid, and sensitive approach for the determination of pesticide residues in fruit juice.

Unsettling East Jersey: Borders of Violence in the Proprietary Era, 1666-1719
Creators: name: Zurcher, Amelia
Publisher: name: University of Massachusetts Amherst
Year: 2019

description: Past histories have studied the disruptive antiproprietary riots that caused great disorder in colonial New Jersey. This study contextualizes this well-known history alongside other violent events of the Mid-Atlantic region that contributed to eighteenth century antagonisms in East Jersey, such as intercolonial rivalry for authority between administrators of New York and New Jersey and impending war between colonial and Lenape populations. It also looks to earlier periods of East Jersey history to trace the roots of eighteenth century conflicts. Legal confusions resulting from the early proprietary grants, Dutch reconquest, and pre-proprietary settlement created conditions that opponents later challenged. By revealing the tremendously tense and uncertain political, social, and economic circumstances of East Jersey’s early proprietary years, the sense of competition and desperation for stability can be better understood. This master’s thesis argues that early social and legal issues introduced by the early proprietary years persisted beyond the proprietary period and were influential preconditions for later tensions among Euro-American and Native peoples. This study argues that East Jersey’s unique and changing proprietary system created confusion and increasingly divided interests among the people of the Mid-Atlantic. As each of these conflicts remained unresolved within colonial and Native societies for nearly a century, they further frustrated social relations within East Jersey, often leading to violence among local Euro-American and Native groups. I examine this history with expanded temporal analysis, demonstrating that conflicts created by the early proprietary foundations of East Jersey, grew in the late proprietary period and persisted beyond the proprietary years.

description: We study the Landau damping of the surface plasmon resonance of metallic nanoparticles embedded in different environments of experimental relevance. Important oscillations of the plasmon linewidth as a function of the radius of the nanoparticles are obtained from numerical calculations based on the time dependent local density approximation. These size-oscillations are understood, within a semiclassical approximation, as a consequence of correlations in the spectral density of the nanoparticles. We treat inert matrices, as well as the case with an unoccupied conduction band. In the latter case, the plasmon lifetime is greatly reduced with respect to the inert case, but the non-monotonous size-dependence persists.

Effect of Chemotherapeutic Treatment Schedule on a Tissue Transport Model
Creators: name: Ganz, Dan E
Publisher: name: University of Massachusetts Amherst
Year: 2014

description: Current chemotherapeutic treatment schedule prediction methods rely heavily on PK/PD-based models and overlook the important contribution of tissue-level transport and binding. Tissue-level transport and binding phenomena are essential to understanding drug delivery and efficacy in tumors. Drugs with desirable PK/PD properties often fail in vivo due to poor tissue-level transport. We developed an in silico method to predict the effect of treatment schedule on efficacy that couples PK/PD with tissue-level transport. Treatment schedules were implemented on theoretical drugs with different PK/PD and transport properties. For each drug with a given clearance rate, diffusivity, and binding, treatment schedules consisting of one to 20 doses were simulated. Results show that at binding constants around one, high diffusivities, and high clearance rates, implementation of a treatment schedule becomes more significant. At low clearance rates, regardless of tissue-level transport and binding, one dose was predicted to be most efficacious. Tissue Drug Exposure (TDE) was shown to be to a crucial factor for treatment schedule efficacy. Efficacy was improved by increasing TDE. Implementation of a treatment schedule with more doses than one curbed the effect of poor retention with drugs. This model investigates the effect of treatment schedule on a tissue transport model and shows implementation of a proper dosing regimen is crucial to maximize TDE and chemotherapeutic efficacy.

description: This study explores the role of social media in modern business communication, focusing on customer relationship management, marketing, and crisis communication. With 91% of U.S. businesses using social media for marketing by 2021, platforms like Facebook and Instagram have transformed business strategies. The research employed a mixed-method approach, surveying 150 business owners and analyzing case studies of brands like Nike and Starbucks. Results show a 20% increase in customer loyalty for businesses actively engaging on social media, while 78% of companies with crisis plans are better equipped to manage reputation. Conclusions emphasize the importance of real-time engagement and tailored strategies to foster customer loyalty and mitigate crises.

We study the double Borel sum rule for the three point function of two pseudoscalar and one vector meson current. We find that the momentum dependence of the form factors is different if the $D$ or the $J/ψ$ meson is off-shell, but they lead to the same coupling constant in the $J/ψD D$ vertex.

The Women's Action: Participation through Resistance
Creators: name: Roberts, Michael
Publisher: name: University of Massachusetts Amherst
Year: 2019

description: Albuquerque, New Mexico, similar to many cities in the western and southwestern United States, continues to build large scale business and housing developments. In response, communities most affected by urban sprawl challenge local government decisions to approve such developments, citing concerns for environmental, cultural, and economic well-being. My thesis explores one such community effort to protect land and water resources within the historic Atrisco land grant, located southwest of the city of Albuquerque. In particular, I examine an event that occurred May 28th, 2015 when a group of concerned women and children disrupted a Bernalillo County special zoning meeting where a five member board of county commissioners denied community appeals to reject approval of a 14,000 acre development called Santolina. I employ ethnographic methods of in-depth interviews, participant observation, and secondary data collection to provide a rich description of the Women’s Action as an act of resistance. I situate my ethnographic account within the scholarship of Ewick and Silbey (1995; 1998; 2003) who empirically derive a theory of everyday acts of resistance as momentary reversals of hierarchical power relations embedded in institutional space. My research offers insights into how communities both engage in and disrupt public participation processes.
Gravitational Waves from Phase Transition in Minimal SUSY $U(1)_{B-L}$ Model

Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: Many extensions of the Standard Model include a new $U(1)$ gauge group that is broken spontaneously at a scale much above TeV. If a $U(1)$-breaking phase transition occurs at nucleation temperature of $O(100)$-$O(1000)$~TeV, it can generate stochastic gravitational waves in $O(10)$-$O(100)$ Hz range if $β_{\rm n}/H_{\rm n}=1000$, which can be detected by ground-based detectors. Meanwhile, supersymmetry (SUSY) may play a crucial role in the dynamics of such high-scale $U(1)$ gauge symmetry breaking, because SUSY breaking scale is expected to be at TeV to solve the hierarchy problem. In this paper, we study the phase transition of $U(1)$ gauge symmetry breaking in a SUSY model in the SUSY limit. We consider a particular example, the minimal SUSY $U(1)_{B-L}$ model. We derive the finite temperature effective potential of the model in the SUSY limit, study a $U(1)_{B-L}$-breaking phase transition, and estimate gravitational waves generated from it.

Predictors of Cognitive Decline in a Multi-Ethnic Sample of Midlife Women: A Longitudinal Study
Creators: name: Dixon, Jasmine
Publisher: name: University of Massachusetts Amherst
Year: 2020

description: Hypertension, diabetes, depressive symptoms, and smoking are predictors of cognitive decline in late life. However, it is not known if these risk factors are associated with cognition during midlife orif the associations between these risk factors and cognition vary by race. This longitudinal study hypothesized that (1) the risk factors would predict cognitive decline in midlife, (2)African Americans would have greater cognitive decline than European Americans and East Asians, and (3) there would be stronger associations between risk factors and cognition for African American women compared to European American and East Asian women. Participants (aged 42-52) were European American (n= 1,000), African American (n= 516), and East Asian (n= 437) women from the Study of Women’s Health Across the Nation who were studied for 8 years. Risk factors (i.e., diabetes, hypertension, smoking, and depressive symptoms) and cognitive outcomes (i.e., episodic memory, processing speed, and working memory) were measured at multiple timepoints. Two-level hierarchical linear models tested change in cognition over time controlling for income, education, and age. African Americans had lower scores than European Americans and East Asians on all cognitive outcomes. East Asian smokers had greater episodic memory decline compared to European American smokers. Depressive symptoms did not adversely impact processing speed for East Asian relative to European Americans. Contrary to our hypothesis, hypertension was associated with improved processing speed over time for African Americans compared to European Americans. Racial disparities in cognition were evident for African American women.

description: We consider the weak decays of a B meson to final states that contain a S-wave radially excited vector meson. We consider vector-pseudoscalar final states and calculate ratios of the type $B \to ρ^{\prime} π/B \to ρπ$, $B \to ω^{\prime} π/B \to ωπ$ and $B \to ϕ^{\prime} π/B \to ϕπ$ where $ρ^{\prime}$, $ω^{\prime}$ and $ϕ^{\prime}$ are higher $ρ$, $ω$ and $ϕ$ S-wave radial excitations. We find such decays to have larger or similar branching ratios compared to decays where the final state $ρ$, $ω$ and $ϕ$ are in the ground state. We also study the effect of radial mixing in the vector system generated from hyperfine interaction and the annihilation term.

"What Can I Possibly Achieve As A Necessity-Driven Entrepreneur?" The Impact Of The Cultural Component Of The Entrepreneurial Ecology On Possible Future Entrepreneur Selves
Creators: name: Dye, Bruce G.
Publisher: name: University of Leicester
Year: 2019
Subjects: Uncategorized

description: This study focuses on necessity-driven entrepreneurs, seated within the entrepreneurial ecology where culture and individuals intersect. It is responding to the poor understanding of necessity-driven entrepreneurs in extant literature. Specifically, there is not a comprehensive, theoretically informed understanding of necessity-driven entrepreneurs and how entering entrepreneurship from a position of social disadvantage impacts aspirations and behaviors. As such, the study is concerned with how culture impacts entrepreneurial aspirations and resulting entrepreneurial behavior, framed by theories of entrepreneurship, culture, possible future selves, and the entrepreneurial ecology. The study was guided by a general research question that probed the impact of culture on the possible future selves of necessity-driven entrepreneurs. It was supported by specific research questions focused on necessity-driven entrepreneurs’ needs, dreams, fears, and the impact of culture. A systematic, yet flexible, qualitative research process was used, informed by interpretivism and constructivism. Thematic analysis was used to facilitate discovery of propositions that can apply to other similar, necessity-driven entrepreneurs in similar contexts. It was found that the needs necessity-driven entrepreneurs are trying to meet are likely to be non-financial and their entrepreneurial dreams and fears are distinctly social. Their belief that they can achieve their needs through entrepreneurship and their possible future entrepreneur selves are sensitive to signals from culture. It was also found that necessity driven entrepreneurs are likely to interpret signals from culture that are encouraging, discouraging, mixed, and sometimes insulting and derogatory. Discouraging signals negatively impact possible future entrepreneur selves and result in risk averse behavior. Finally, it was found that necessity-driven entrepreneurs' social disadvantage may prompt them to act on long-standing entrepreneurial aspirations. To better understand necessity-driven entrepreneurship, we need to broaden our lens beyond assumptions that it is necessarily a profit-motivated, individual-centric activity and simultaneously consider the role that culture plays, within the context of the entire entrepreneurial ecology.

description: We study topological features of interacting spin- 1 2 particles in one-dimensional state-dependent optical lattices. Due to the co-translational symmetry, we introduce the center-of-mass Zak phase with the help of center-of-mass momentum. There appear topological bound states composed by two particles in different spin states via tuning hopping and interaction strengths. Under symmetric open boundary conditions, topological edge bound-states appear as a result of the non-trivial center-ofmass Zak phase of bound-state band, which is protected by the center-of-mass inversion symmetry. The interaction plays a crucial role in the appearance of topological bound states and the system becomes completely trivial if the interaction is switched off. By periodically modulating the hopping and interaction strengths, we show how to implement topological Thouless pumping of bound states, in which the quantized shift of center-of-mass can be described by a non-trivial center-of-mass Chern number.

description: Agriculture is the most significant contributor to Ethiopia’s economy. Most of the agricultural production is under rainfed conditions and thus extremely sensitive to rainfall variability. Irrigation development, including smallholder irrigation, is used by the Ethiopian Government to attempt to mitigate the effects of rainfall variability. In this study, we look at smallholder irrigation - modern and traditional irrigation systems. A detailed description of the cropping patterns is given. The stochastic frontier production function approach is used to estimate technical inefficiency, and constraints to production are analyzed. Since the traditional system is found to be efficient but on a lower production frontier, the study shows that significant gains can be made by raising the frontier of the traditional systems and increasing the efficiency of the modern systems. Among the production constraints studied were land preparation, soil fertility, weed control, pests and diseases, soil erosion, input access and moisture deficiency. The most significant constraints on the irrigated systems were input access and moisture deficiency.
Acoustogalvanic effect in Dirac and Weyl semimetals

description: The acoustogalvanic effect is proposed as a nonlinear mechanism to generate a direct electric current by passing acoustic waves in Dirac and Weyl semimetals. Unlike the standard acoustoelectric effect, which relies on the sound-induced deformation potential and the corresponding electric field, the acoustogalvanic one originates from the pseudo-electromagnetic fields, which are not subject to screening. The longitudinal acoustogalvanic current scales at least quadratically with the relaxation time, which is in contrast to the photogalvanic current where the scaling is linear. Because of the interplay of pseudoelectric and pseudomagnetic fields, the current could show a nontrivial dependence on the direction of sound wave propagation. Being within the experimental reach, the effect can be utilized to probe dynamical deformations and corresponding pseudo-electromagnetic fields, which are yet to be experimentally observed in Weyl and Dirac semimetals.

description: We discuss how the inclusion of singular gauge fields in the partition function for QCD can lead to a domain-like picture for the QCD vacuum by virtue of specific conditions on quantum fluctuations at the singularities. With a simplified model of hyperspherical domain regions with interiors of constant field strength we calculate the basic parameters of the QCD vacuum, the gluon condensate, topological susceptibility, string constant and quark condensate, and briefly discuss confinement of dynamical quarks and gluons.

description: Middle cerebral artery occlusion (MCAO) is the most common method of inducing ischaemic stroke in laboratory rodents and has a significant impact on their welfare. This thesis investigated three refinements in experimental stroke studies. Firstly, the role of environmental enrichment was investigated using preference tests, measure of neurogenesis and functional outcomes. Mice demonstrated consistent avoidance of the enriched environment yet enrichment did increase hippocampal cell proliferation. Rats showed no significant preference for the standard environment at any time point but experienced no increase in neurogenesis in response to enriched housing. Differences between sexes and light cycle phases were observed in both mice and rats. Thus, these findings demonstrate the complexity of environmental enrichment and highlight the need to tailor protocols to the animals being used. When delivered prior to and/or following MCAO, enrichment did not significantly improve outcome in welfare measures or behavioural tests, although changing environment post-MCAO did appear to be detrimental, and increased neurogenesis accompanied post-stroke enrichment. Secondly, the benefit of a pre-stroke surgical intervention was investigated. The craniotomy surgery, has been shown to improve survival and weight loss in hypertensive rats. No effect of the intervention was seen on lesion volume or brain swelling and no welfare benefit was seen in normotensive rats. Finally, the ability to monitor welfare using temperature and activity measurements from telemetry devices was investigated. Body temperature of young rats was significantly altered by MCAO surgery and species differences were found, with mice having significantly lower body temperature than young rats. Correlations between physiological parameters and outcome measures post-MCAO were promising, particularly neurological score, which showed significant correlations with body temperature of mice and rats. Overall, this thesis presents promising results, but further work is required to draw concrete conclusions on refining experimental stroke studies to improve animal welfare.
Current facilitation by plasmon resonances between parallel wires of finite length

description: The current voltage (IV) characteristics for perpendicular transport through two sequentially coupled wires of finite length is calculated analytically. The transport within a Coulomb blockade step is assisted by plasmon resonances that appear as steps in the IV characteristics with positions and heights depending on inter- and intrawire interactions. In particular, due to the interwire interactions, the peak positions shift to lower voltages in comparison to the noninteracting wires which reflects the facilitation of current by interactions. The interwire interactions are also found to enhance the thermally activated current.

description: The Niger River Basin covers 7.5% of the African continent and is shared between nine riparian countries. The human population of the basin is growing at an average annual rate of about 3%, which makes the Niger River Basin one of the areas with the highest fertility rates in the world. The desert margin is expanding; climate change is negatively impacting rainfall; and urbanization, industrialization, and the human and livestock population are threatening the quantity and quality of available water resources. The basin population already suffers from chronic poverty. Based on a literature review, this paper suggests some key water-related and other interventions that are capable of easing the basin's development challenges.

description: In this paper we study CP violation in $B\to PP$ decays in the Standard Model using SU(3) flavor symmetry. With SU(3) symmetry only seven hadronic parameters are needed to describe $B\to PP$ decays in the SM when annihilation contributions are neglected. The relevant hadronic parameters can be determined using known experimental data from $B\to ππ$ and $B\to K π$. We predict branching ratios and CP asymmetries for some of the unmeasured $B \to PP$ decays. Some of the CP asymmetries can be large and measured at B factories. The effects of annihilation contributions can also be studied using present experimental data. Inclusion of annihilation contributions introduces six more hadronic parameters. We find that annihilation contributions are in general small, but can have significant effects on CP asymmetries and some $B_s \to PP$.

description: Como hoje em dia todos sabemos, a história do Dia Triunfal a propósito de Alberto Caeiro é um mito com um fundo de verdade. Menos sabido é que Pessoa, na mesma carta de 1935 em que contou como lhe aparecera o guardador de rebanhos, também criou um mito “triunfal” sobre Álvaro de Campos. Assim: “Num jacto, e à máquina de escrever, sem interrupção nem emenda surgiu a ‘Ode Triunfal’ de Álvaro de Campos – a Ode com esse nome e o homem com o nome que tem.” A referida ode, na verdade, não foi escrita à máquina, mas à mão, e foi bastante emendada. A ousadia efervescente de Campos também foi uma construção, utilizada para desconstruir os modelos literários que então prevaleciam. Álvaro de Campos consubstanciou o espírito e a ambição da revista Orpheu, que serviu, por sua vez, como um contexto para definir e destacar o seu génio não-aristotélico. O heterónimo era um grito libertador para Pessoa, para a poesia portuguesa e para o leitor com ouvidos para ouvir. Mas como é que surgiu exactamente? Qual era a sua relação, geneticamente falando, com Alberto Caeiro e Ricardo Reis? Em que consistia o triunfalismo da sua ode inaugural e do resto do seu percurso poético e “vivencial”? O presente trabalho tenta responder a estas perguntas através de uma leitura atenta das cartas que Sá-Carneiro enviou para Pessoa no Verão de 1914, de alguns poemas de Álvaro de Campos (confrontados, em dois casos, com poemas de Carlos Drummond de Andrade), de rascunhos de poemas, atribuíveis a Campos ou a Caeiro, e de documentos em prosa assinados por Pessoa e por diversos heterónimos.

description: This paper studied the fabrication of new hybrid-type poly(3,4- ethylene dioxythiophene) (PEDOT)/sulfonated graphene oxide electrode-based polymer actuator produced by film casting method. Sulfonated Poly(1,4-phenylene ether-ether sulfone) (SPS) ion-exchange polymer membrane-based ionic polymer composite actuators were fabricated using the different concentration of SGO. The characterization and actuation were demonstrated. By altering SGO concentration, four different SPS based membrane actuators were analyzed. The effects of SGO concentration on the morphology, proton conductivity, ion exchange capacity, and water uptake capability were studied. The maximum tip displacement and force by varying concentration of SGO were evaluated for the actuation performance.

description: Validating the black-hole no-hair theorem with gravitational-wave observations of compact binary coalescences provides a compelling argument that the remnant object is indeed a black hole as described by the general theory of relativity. This requires performing a spectroscopic analysis of the post-merger signal and resolving the frequencies of either different angular modes or overtones (of the same angular mode). For a nearly-equal mass binary black-hole system, only the dominant angular mode ($l=m=2$) is sufficiently excited and the overtones are instrumental to perform this test. Here we investigate the robustness of modelling the post-merger signal of a binary black hole coalescence as a superposition of overtones. Further, we study the bias expected in the recovered frequencies as a function of the start time of a spectroscopic analysis and provide a computationally cheap procedure to choose it based on the interplay between the expected statistical error due to the detector noise and the systematic errors due to waveform modelling. Moreover, since the overtone frequencies are closely spaced, we find that resolving the overtones is particularly challenging and requires a loud ringdown signal. Rayleigh's resolvability criterion suggests that in an optimistic scenario a ringdown signal-to-noise ratio larger than $\sim 30$ (achievable possibly with LIGO at design sensitivity and routinely with future interferometers such as Einstein Telescope, Cosmic Explorer, and LISA) is necessary to resolve the overtone frequencies. We then conclude by discussing some conceptual issues associated with black-hole spectroscopy with overtones.
