Application Of A Synergetic Approach To The Problem Of Synthesizing An Intelligent Control System For Chemical Reactors, Komil Usmanov

Karakalpak Scientific Journal

The article deals with the synthesis of effective algorithms for controlling a chemical reactor and developed a intelligent synergistic controller for a class of indefinite nonlinear dynamic systems. A synergetic control scheme is proposed for solving the control problem for nonlinear systems. Non-linear systems with configurations and parameters that change over time require a completely non-linear model and adaptive control scheme for a practical operating environment. The synthesis of control laws is performed by the method of analytical design of aggregated controllers (ADAR).

Elevated Substitution Rates Among Wolbachia-Infected Mosquito Species Results In Apparent Phylogenetic Discordance., James E. Russell, Michael Saum, Rebekah Williams

Georgia Journal of Science

As one of the most widely distributed bacterial cytoplasmic symbionts on earth, Wolbachia pipientis Hertig serves as a model organism for the understanding of host-symbiont interactions. Many mosquito species are infected with Wolbachia strains that induce a form of reproductive manipulation called cytoplasmic incompatibility, in which infected females gain a reproductive advantage over uninfected females in mixed infection populations. The selective advantage of cytoplasmic incompatibility often results in a population sweep of Wolbachia and co-transmitted mitochondrial genomes. Mitochondrial evolution and phylogenetic inferences drawn from mitochondrial gene sequences are thus potentially compromised by reproductive manipulating symbionts, like Wolbachia. Our initial analyses ...

The Relationship Between Perceived Stress And Disordered Eating In Undergraduate Students During The Covid-19 Pandemic, Caroline G. Martin

Gettysburg College Headquarters

The COVID-19 pandemic has affected and imposed challenges on nearly everyone, including college students. Despite their already stressful situations, previous research has demonstrated increased stress levels among college students during the COVID-19 pandemic. Additionally, research has also shown an increase in disordered eating for college students during the pandemic. However, few studies have investigated the relationship between both perceived stress and disordered eating during the COVID-19 pandemic. Therefore, the present study used a correlational design to investigate a potential association between perceived stress and disordered eating among undergraduate college students during the COVID-19 pandemic. By administering the EAT-26, the CSSEC ...

Single-leg balance control is very important in injury prevention (such as reducing the chance of falls and ankle sprains) and sport performance. Although compression garments (CGs) have been used for various purposes, it is unclear if wearing CGs can improve single-leg balance in healthy individuals. The purpose of the study was to examine if wearing CGs (pants) could enhance single-leg balance, and to compare the impact of wearing CGs on single-leg balance between conditions with and without extrinsic visual feedback. Twenty-five healthy individuals (aged 20-30 years) participated ...

A Test Of Food Partitioning Between The Aquatic Larvae Of Two Parapatric Species Of Two-Lined Salamander (Eurycea Bislineata Species Complex) In A Zone Of Sympatric Contact, Carlos D. Camp, S. Michael Owensby, Emily Benfield, Jessica A. Wooten

Georgia Journal of Science

Phylogenetically related species with similar ecologies often partition resources when in sympatry. Food is an important factor in the co-occurrence of sympatric salamanders, and food partitioning occurs in a variety of sympatric, similar species. Several members of the Two-lined Salamander (Eurycea bislineata) species complex are largely parapatric but co-exist within a narrow zone of sympatric contact. Because larvae of these salamanders frequently occur in very high densities, we tested the hypothesis that larvae of the Blue Ridge Salamander (E. wilderae) and the Southern Two-lined Salamander (E. cirrigera) partition food in sympatry in northeastern Georgia. We predicted that the diets of ...

Using Color To Identify Neotropical Parrots In Early Modern European Art: Recognizing Limitations And Avoiding Pitfalls Through Integration Of Scientific And Artistic Knowledge, Deniz Martinez

The Confluence

Colorful Neotropical parrots were amongst the first and most frequent exotic animals to be imported by Europeans from the “New World” of the Americas, becoming key figures in what would become known as the Columbian exchange. There has been an ongoing effort to locate and identify images of Neotropical parrots in the visual record of early modern Europe, with the classification of many remaining unsettled in the scholarship. Proper identification of these images can be valuable data for reconstructing historical biogeography and transatlantic trade; especially compelling is the potential of certain “mystery parrots” in the visual record to support the ...

Evaluation Of The Humoral/Fc-Mediated Immune Responses To An Adenovirus-26 Viral Vector/Gp140 Subunit Combined Vaccine Regimen As A Prophylactic Hiv-1, Nathan E. Adam

Channels: Where Disciplines Meet

Background and Introduction: HIV is one of the most problematic pandemics to date, currently infecting upwards of 38 million people worldwide (“The Global HIV/AIDS Epidemic,” 2020). Although infection and mortality rates have generally decreased, current prophylactic (preventive) measures against HIV-1 acquisition have shown major weaknesses that could be remedied with a vaccine (Pitisuttuthum & Marovich, 2020). Manufacturing an effective, prophylactic HIV-1 vaccine, however, is not without challenges - namely design/selection of vaccine-delivered immunogens (antigens) and elicitation of proper immune responses to HIV-1 antigens (Ng’uni et al., 2020). Fortunately, despite past, unsuccessful research, studies within the past 10-15 years have begun to elucidate immune correlates of protection against HIV-1 acquisition, specifically IgG1/IgG3 antibody (Ab) production, as well as non-neutralizing, Fc-Mediated effector functions (Rerks-Ngarm et al., 2009). Excitingly, studies released in the last 3 years, which use Adenovirus serotype-26 (Ad26) vector (Custers et al., 2020) show promising signs that an effective HIV-1 vaccine could become a reality (Baden et al., 2020; Barouch et al., 2018). Thus, for this presentation, I hope to show that Johnson & Johnson’s two new Ad26-based vaccines (combined with booster vaccines) sufficiently elicit key immune correlates of protection to warrant an Ad26 vector-based regimen’s testing past Phase 1/2a clinical trials. Results ...
