description: Mass spectrometry (MS) has become one of the most powerful and versatile tools for chemical analysis due to its ultra-high sensitivity, high throughput, ease of automation, and the large amount of information obtained. Nowadays, MS is extensively used in many tasks, such as identification and quantitation of drug metabolites, analysis of the products of biomass pyrolysis, and study of reactive intermediates, to name a few. However, these mass spectrometric analyses are not without challenges. For example, the requirement for quantifying trace amounts of substances in a complex mixture constantly pushes the detection limit of mass spectrometers, and the increased sample complexity demands higher and higher mass resolution. Therefore, MS is constantly evolving to address more difficult analytical challenges. A variety of MS techniques have been developed over the years, including soft ionization methods that facilitate mass spectrometric analysis of macromolecules, such as proteins and antibodies that enables the development of new therapeutic agents, benchtop high-resolution mass spectrometers, such as the orbitraps that can be used to analyze some of the most complex mixtures, and portable mass spectrometers which can be used in the home and garden and even in cancer surgery. Besides its applications in chemical analysis, MS can serve as a unique tool for the fundamental study of gas-phase ion/molecule reactions, these gas-phase reactions can be used to better understand the reactivities of many reactive intermediates and to obtain structural information for unknown analytes. This thesis is aimed at addressing challenges involved in mass spectrometric analyses of isomeric drug metabolites (Chapter 4), quantitation of drug metabolites by using tandem mass spectrometry coupled with liquid chromatography (LC-MS/MS) (Chapter 5), delineating cellulose depolymerization mechanisms upon fast pyrolysis by using pyrolysis-tandem mass spectrometry (py-MS/MS) (Chapter 6), and studying the reactivities of vinyl cation intermediates (Chapter 7). An overview of the dissertation research is given in Chapter 1, the instrumentation and principles of linear quadrupole ion trap (LQIT) mass spectrometer are discussed in Chapter 2, and the organic synthesis performed for several studies is detailed in Chapter 3.

description: In recent decades there has been great interest to produce novel bio-based composites to reduce carbon footprint without sacrificing the necessities that society demands. To achieve a more sustainable future, research in cellulose biopolymers has risen to the forefront. Impressive mechanical, thermal and optical properties along with its abundant biomass has made nanocellulose (NC) the subject of intense research in the area of electronics, drug delivery, sensors, selective filters, and structural materials, to name a few. The practical utility of any cellulose-based materials requires a more complete understanding of how the fundamental structure affects final performance. This thesis examines several avenues to obtain novel materials by considering processing parameters and preparation methods for working with raw nanocellulose materials, and mechanochemical approaches for surface grafting to obtain modified CNs with improved dispersion in organic media. Lastly, the synergy between the two studies and its impact on advanced materials and nanocomposites is discussed. The low cost and wide availability of cellulose nanofibers (CNF), a refined form of cellulose microfibrils, make these an ideal starting material for our studies. However, the aggregated states of freeze-dried CNFs hinder its use as an additive for reinforcing polymer blends or functional films. The use of tert-butyl alcohol (TBA) as a stabilizer in pharmaceutical drugs has been well studied for its effectiveness in facilitating redissolution and extending product shelf life. Lyophilization of aqueous CNF slurries treated with various amounts of TBA produced a more porous material that could be redispersed with superior colloidal stability relative to untreated freeze-dried CNFs. Furthermore, CNFs lyophilized from aqueous TBA mixtures could be subjected to mild mechanochemical reactions (horizontal ball milling) to produce esterified nanofibers with high degrees of substitution (DS) and good dispersibility profiles in organic solvents. This solventless technique allowed for a variety of carboxylic acids to be grafted onto CNF surfaces. Finally, investigations of new materials with technological utility have been explored using networks of CNFs modified with oleic acid. These can be cast into superhydrophobic (SHP) films having a hierarchical structure characteristic of a self-similar material, with a wettability comparable to that of the lotus leaf. The SHP surface can also be regenerated after surface fouling or physical damage.

ENHANCING STOCK MARKET FORECASTING THROUGH TIME SERIES DECOMPOSITION TECHNIQUES
Creators: name: Marko, Novak

Publisher: name: AYDEN JOURNAL
Year: 2025

description: Forecasting stock exchange index values is a fundamental pursuit in financial analysis, traditionally achieved by modeling past index values. However, an alternative approach involves separately forecasting prices for each individual stock comprising the index and then aggregating these forecasts to predict the index value, considering corresponding weights. This study explores the efficacy and utility of such separate forecasting methods in comparison to conventional approaches. Drawing upon the concept of market efficiency posited by Fama (1970), which suggests that direct forecasting may be futile, let alone the indirect method of separate forecasting, there arises a critical inquiry into the rationale and practicality of adopting such techniques. This paper delves into the implications of both methods, considering their theoretical underpinnings and empirical performance.

description: Numerous studies have examined the dynamics of multiple shareholders in firms, primarily focusing on aspects of firm performance and value, as evidenced by seminal works such as Lehmann and Weigand (2000), Gutierrez et al. (2003), Gutierrez et al. (2004), Maury (2004), Laeven and Levine (2008), and Attiq, Ghoul, and Guedhami (2009), among others. Additionally, a subset of literature has delved into the intricate relationship between large shareholders and firm policies, as explored by Cronqvist and Fahlenbrach (2007), Ghachem (2008), and Attiq et al. (2008). However, there remains a notable gap in the literature regarding the nuanced interplay between multiple shareholders, firm performance, and firm policies. This study seeks to address this gap by examining the multifaceted dynamics among multiple shareholders, firm performance metrics, and the formulation and implementation of firm policies. By employing a comprehensive analytical framework, this research aims to shed light on the intricate mechanisms through which multiple shareholders influence both the financial and strategic dimensions of firms

description: Neutrophils are critical for innate immunity, acting as the body's first line of defense. They are terminally differentiated and are short-lived white blood cells. Cyclin-dependent kinases (CDKs), traditionally associated with cell cycle progression are now known to regulate crucial neutrophil functions: CDK2 influences neutrophil migration, CDK4 and 6 regulate neutrophil extracellular traps (NETs) formation, CDK5 controls degranulation, and CDK7 and 9 are pivotal for apoptosis and inflammation resolution.Despite extensive studies on CDK2 in cell cycle regulation, its role in neutrophil function remained uncharacterized until recently. Inhibiting CDK2 kinase activity significantly impairs neutrophil migration. Using phosphoproteomic methods, we identified key proteins in multiple cellular pathways affected by CDK2 inhibition, with Cyclin D3 emerging as a binding partner. Direct substrates of CDK2, including RCSD1, CCDC6, LMNB1, and STK10, were found to be essential for neutrophil motility. These findings provide insights into the molecular mechanisms underlying this process. Consequently, targeting CDK2 or its substrates presents potential therapeutic strategies for conditions involving aberrant neutrophil migration or neutrophil-mediated inflammation, offering new avenues for treating neutrophil-dominant inflammatory diseases and advancing our understanding of neutrophil regulation.Emergency granulopoiesis, a response to severe inflammation, involves the increased production of neutrophils in hematopoietic tissue. Understanding the body's response to severe inflammation necessitates more precise and less invasive methods to track neutrophil development. To distinguish newly formed neutrophils from existing ones in the occurrence of emergency granulopoiesis, we developed a transgenic zebrafish line expressing a time-dependent GFP-RFP switch fluorescent protein, enabling quantification through simple GFP/RFP ratiometric imaging. This method bypasses the limitations of traditional photo-labeling, which requires strong laser lines and label subsets of existing neutrophils.

description: The emergence of the COVID-19 pandemic in local communities, businesses, and nations worldwide precipitated an unprecedented level of uncertainty, necessitating a rapid and coordinated global response to mitigate its adverse effects on humanity. This paper contends that the existence of robust information and communication technology (ICT) systems played a pivotal role in averting a more catastrophic outcome of the pandemic. Unlike the time-consuming development and deployment of vaccines, the pre-existing ICT infrastructure swiftly mobilized to address the overwhelming challenges posed by the pandemic. Through an analysis of the global response to COVID-19, this paper highlights the indispensable role of ICT systems in facilitating communication, disseminating vital information, enabling remote work and education, and supporting healthcare systems during times of crisis. Furthermore, it explores how various ICT tools such as telemedicine, remote monitoring, contact tracing apps, and data analytics contributed to the containment and management of the pandemic. By leveraging existing digital technologies and platforms, governments, businesses, and communities were able to adapt to the rapidly evolving situation, implement effective mitigation strategies, and coordinate collaborative efforts on a global scale. This paper underscores the resilience and adaptability of ICT systems in the face of unprecedented challenges, emphasizing their critical role as a foundational infrastructure for societal resilience and response to future crises

"Shea Moisture is Cancelled": Racialized Identification in the 2017 Shea Moisture Crisis
Creators: name: Adekunle, Tiwaladeoluwa
Publisher: name: Purdue University Graduate School
Year: 2019
Subjects: Communication studies

description: In 2017, Shea Moisture, a company that created natural hair products targeted primarily toward Black women, released an online video in which ostensibly white and multiracial women discussed the struggles they encountered in accepting their natural hair. This video led to a public relations crisis for the organization as a result of its perceived exclusion of the organization’s core public--Black women with 4C hair, who arguably experience the highest levels of discrimination on account of their natural hair. This study explored the role of identity and identification in this crisis by conducting a qualitative content analysis of identification types in Black men and women’s online responses to the video. Emotions present in the online posts were used as rhetorical indicators of deidentification, ambivalent identification, identification or disidentification. The findings of this study, contextualized within the socio-political context of the crisis, suggest that responses to Shea Moisture’s video were informed by : its public’s identification with one another, their construal and co-construction of the organization’s identity as a Black business, and their identification with the organization on the basis of this identity. This study reinforces the role played by publics in co-constructing an organization’s identity and reveals the importance of sociopolitical realities and uneven power relations to publics’ identification. This study also introduces the concept of “protected identification” to describe a mode of identification that informed by a socio-political context wherein marginalization exists, comes with a unique set of expectations for the actions of an organization.

description: Since the 1970s, Nigeria's economy has been heavily reliant on crude oil, leading to the neglect of other sectors, particularly agriculture. This overdependence on oil has left the economy vulnerable to fluctuations in international crude oil prices and underscored the need for diversification. Calls for economic diversification have grown louder over the years, emphasizing the potential benefits of developing the non-oil sector. This review examines Nigeria's economic landscape, tracing the evolution of its dependence on oil and the resultant neglect of other sectors. It highlights the imperative of diversifying the economy to mitigate risks associated with oil price volatility and unlock the untapped potential of non-oil sectors.

ancillary vegetation measurements

description: This document describes the measurement of ancillary vegetation variables at ICOS ecosystem stations in forests. These variables are Green Area Index (GAI), Aboveground Biomass (AGB), and litter biomass. In summary, they are measured for the following aims and with the following methods:
- GAI is measured to explain seasonal variation in ecosystem-atmosphere fluxes and is measured indirectly with Digital Hemispherical Photography (DHP) or a linear ceptometer. The choice of method depends on the GAI (seasonal max GAI<6 m² m-2 requires DHP, seasonal max GAI>6 m² m-2 requires ceptometer), however the choice of method should be discussed between the station PI and the ETC. The sensor type should be kept constant over time.
- AGB is measured to estimate Aboveground Net Primary Productivity (ANPP) and lateral carbon flow through harvest. AGB is measured by measuring diameter at breast height (DBH), stem height and allometric relations for overstorey vegetation and destructive measurements for understorey vegetation.
- Litter biomass is measured to correct the yearly ANPP estimated from AGB and is measured with litter traps at the Class 1 stations.
This document is structured in four different sections with the aim to facilitate the use and application:
- Measurements: in this section the sensors, setup and methods to correctly collect the data and info are described. It includes sub-sections on sensors characteristics, practical indication for the setup/collection, info on the sampling design and guidelines for the installation/sampling also respect to other sensors/measurements
- Maintenance: in this section all the maintenance and calibration guidelines are described, including the general timeline.
- Submission: it is the section related to the data preparation and submission to the ETC. It includes the list of all the parameters, the correct formatting and the way to submit them to the database. It is linked to the BADM system needed to submit the metadata and not continuous measurements
- Processing: this section is for internal use of the ETC and describes the processing applied to the single variable/info/sample submitted.
It is important to remind that the exact application of the protocol at site level is also discussed with ETC in order to find agreed solutions for specific cases. If a specific part is relevant only for a specific ecosystem or station Class this is also reported in the document.

Geometric Morphometric Analysis of Third Instar Larvae of Common Blow Fly (Diptera: Calliphoridae) Genera for Forensic Identification
Creators: name: Nigoghosian, Gregory
Publisher: name: Purdue University Graduate School
Year: 2019
Subjects: Forensic biology

description: In terms of forensic entomology, one area that is scrutinized most is the estimation of a minimum post mortem interval (mPMI) based on insects that are present at a crime scene. The identification of the insects found at the scene if the first step to calculate a mPMI. However, currently there are no methods that can present the courts with accurate statistical error rates in identification, because the current methods are reliant on an expert’s use of a morphological key to identify the specimen, and this identification method does not produce a confidence value. This project aimed to test a method of identification using geometric morphometrics that can produce confidence intervals to provide to the courtrooms. Before any identification could start, a standard preservation protocol was developed to ensure that all diagnostic features are preserved, and specimens can be identified in the same way. A clearing method was designed to clear specimens within 24hrs using potassium hydroxide, so they can be dissected and mounted the next day. The dissection of the specimens was a simple six-step procedure to split the mouth hooks, the cuticle and the posterior spiracle. This procedure ensures that all diagnostic features are preserved on a microscope slide. With all of the features preserved, the microscope slide is photographed for storage and an investigator can perform geometric morphometrics to identify the insect. This study tested the application of geometric morphometrics to distinguish between three genera of Calliphoridae (Calliphora,Lucilia, Phormia), from three locations in the US (Delaware, Indiana, California). Results showed significant (p-value: <0.05) variation in shape among all genera. When genera were tested for shape differences based on location, these variations were also significant (p-value: <0.05). The implication of these results is that enough shape difference exists to distinguish between these genera and to distinguish between populations.

description: The informal sector plays a crucial role in the economic landscape of developing countries, contributing significantly to job creation, income generation, and poverty alleviation. In Zimbabwe, the informal sector witnessed notable growth during periods of economic upheaval, including the country's Economic Structural Adjustment Programme (ESAP) and recent economic and political crises. ESAP was marked by widespread retrenchments in both the public and private sectors, while the more recent crisis led to a contraction in formal employment opportunities and a substantial decline in real wages, largely driven by hyperinflation. Consequently, the expansion of Zimbabwe's informal sector can be attributed to the diminishing formal employment prospects and the imperative to supplement formal incomes.

description: Pathogenic ESBL-producing E. coli lineages occur frequently worldwide, not only in a human health context but in animals and the environment, also in settings with low antimicrobial pressures. This study investigated the fitness costs of ESBL-plasmids and their influence on chromosomally encoded features associated with virulence, such as those involved in the planktonic and sessile behaviors of ST131 and ST648 E. coli. ESBL-plasmid-carrying wild-type E. coli strains, their corresponding ESBL-plasmid-“cured” variants (PCV), and complementary ESBL-carrying transformants were comparatively analyzed using growth curves, Omnilog® phenotype microarray (PM) assays, macrocolony and biofilm formation, swimming motility, and RNA sequence analysis. Growth curves and PM results pointed toward similar growth and metabolic behaviors among the strains. Phenotypic differences in some strains were detected, including enhanced curli fimbriae and/or cellulose production as well as a reduced swimming capacity of some ESBL-carrying strains, as compared to their respective PCVs. RNA sequencing mostly confirmed the phenotypic results, suggesting that the chromosomally encoded csgD pathway is a key factor involved. These results contradict the hypothesis that ESBL-plasmid-carriage leads to a fitness loss in ESBL-carrying strains. Instead, the results indicate an influence of some ESBL-plasmids on chromosomally encoded features associated with virulence in some E. coli strains. In conclusion, apart from antibiotic resistance selective advantages, ESBL-plasmid-carriage may also lead to enhanced virulence or adaption to specific habitats in some strains of pandemic ESBL-producing E. coli lineages.

description: To fully optimize devices for solar energy conversion, a comprehensive understanding of how excitons migrate in materials for solar cell devices is crucial. Understanding the mechanisms behind exciton diffusion and energy transfer will enable the fabrication of highly efficient devices. However to thoroughly study exciton properties, techniques implementing high spatial (nm sizes) and temporal (fs time scales) resolution is required. Herein, we utilize transient absorption microscopy (TAM) with 50 nm spatial resolution and 200 fs temporal resolution to elucidate exciton diffusion in polymeric materials for solar energy conversion. While organic devices are inexpensive and require simpler fabrication procedures than inorganic materials, their device efficiencies often suffer due to their semi-crystalline nature, lending to short diffusion lengths which lead to trap sites and inevitably recombination. It has been demonstrated that achieving long-range exciton diffusion lengths is possible through coherence effects. Coherence can be found in an intermediate electronic coupling region where delocalization and localization compete. To exploit coherence effects, we study polymeric systems in which polymer chains are highly aligned via simple and scalable procedures; semiconducting fibers and solution coated films. In studying the fiber, we first implement polarized photoluminesce (PL) to determine optical ansitropy. From the polarized PL and PL images, it is observed that emission intensities are largest when probing along the transition dipole moment of the polymer. This suggests a type of Förester Resonance Energy Transfer mechanism in which excitons hop from one polymer chain to another. Solution coated polymer films are also studied to understand exciton diffusion as a function of deposition methods. By varying the solution concentration as well as coating rate, we are able to tune the morphology of the film. We observe a strong dependence between diffusion constant and deposition parameters, with diffusion constants of ca. 9, 13 and 33 cm2/s for three different films. The results obtained in this thesis are preliminary steps in an effort to elucidate energy transfer mechanisms and rates.
