Solving Edges Deletion Problem Of Complete Graphs, Anwar N. Jasim, Alaa A. Najim

Baghdad Science Journal

As the network size increases, there is an increased probability that some components will fail. It is therefore necessary for the network to be able to maintain the interconnection even in the presence of faulty components. The likelihood of a failure in the connections between stations is higher than that of a failure in the stations themselves because of the nature of many networks. Numerous graph-theoretic methods can be used to examine the reliability and efficacy of a network, and the network's dependability is determined by its connectivity. For a parallel and distributed system, the maximum connection time between any …

Optimizing Encrypted Search In The Cloud Using Autoencoder-Based Query Approximation, Mahmoud Mohamed, Khaled Alosman

Baghdad Science Journal

Searching over encrypted data is critical for secure cloud services. However, encryption reduces search efficiency due to inability to directly compute on ciphertexts. This leads to an inherent tradeoff between privacy and usability that has motivated extensive research on enabling effective encrypted search. Recent work has explored using machine learning models like autoencoders to optimize similarity search under encryption. Autoencoders compress data into low-dimensional vectors capturing semantic information. Documents and queries can be encoded for efficient similarity computation without decryption. However, existing analysis remains limited in scope and scale. The research address these gaps through large-scale experiments and novel optimizations. …

Dynamic Analysis Of Additively Manufactured Tensegrity Structures, Keivan Davami, Russell A. Rowe, Ben Gulledge, Jesse Park, Ali Beheshti, Anthony N. Palazotto, Fariborz Tavangarian, Sadie Beck

Faculty Publications

Herein, we present an analysis, design, and experimental testing of modular prestressed pin-jointed structures constructed from bistable units and inspired by the classical triangular tensegrity prism. Tensegrity structures, characterized by a combination of tension members (cables) and compression members (bars) in a self-equilibrated state, have gained significant attention in engineering over the past two decades due to their unique nonlinear mechanical behavior. The discontinuity of the compression members in tensegrity structures leads to a slightly different failure behavior compared to their lattice structure counterparts, with unprecedented applications. However, traditional fabrication and assembly methods have posed challenges for their widespread adoption. …

Self-Sacrifice And Civilization: American Everyday Heroism And The Carnegie Hero Fund Commission In The Progressive Era, Simon Wendt

Heroism Science

This article examines the multi-layered meanings of civilian heroism around 1900. It argues that the Progressive Era was an important transition period in the history of heroism in the United States, during which definitions of what was regarded as heroic multiplied and no longer revolved solely around military valor or political leadership. Especially everyday heroes received unprecedented media attention. They were seen by many as evidence of the continuing progress of American civilization, which appeared to allow for a peaceful coexistence of individual self-interest and social consciousness. The Carnegie Hero Fund Commission, established in 1904, contributed much to such interpretations …

Variability In Northeastern Early Paleoindian Period Basecamps: Implications For The Peopling Of New Landscapes, Anne Parfitt

Anthropology Theses and Dissertations

The Pleistocene peopling of the Americas remains a process we still do not fully understand. One primary reason for this is that in many regions of North America, it is not always possible to determine whether the earliest archaeological sites represent the activities of pioneering people, or of later populations. One area where the earliest sites are most likely to represent a founding population is Northeastern North America (e.g., the Great Lakes and New England-Maritimes regions), due to the relatively late deglaciation in this area. The earliest sites in this area include a dozen or so large, distinctive basecamps with …

Two Birds, Two Stones: Separating Biodiversity Conservation From Patent Law, Jessie Sadlon

Nebraska Law Bulletin (Selected Issues)

The current decline in biodiversity is faster than any other point in human history.[1] Overexploitation is the leading driver of biodiversity loss; species are harvested at unreplenishable rates. Government, non-government, and industry representatives are searching for direction in addressing this rapid species loss. In particular, the World Intellectual Property Organization (“WIPO”) is looking to channel biodiversity conservation through patent systems by instituting an origin disclosure requirement within the patent application process. This paper explores the intersection of biodiversity and innovation, contending the origin disclosure requirement is an unjustified, ineffective mechanism to effectuate biodiversity conservation.

Part II describes the biodiversity crisis …

Regulation And Function Of Mec-2 Alternative Splicing In Single Cells, Canyon Calovich-Benne

Biological Sciences Theses and Dissertations

One mechanism for generating diversity at the single cell level is selective expression of a unique set of transcription factors (TFs) and RNA binding proteins (RBPs). These regulatory factors contribute to functions of cells by controlling cell fate, turning genes on and off, and processing of transcripts either co- or post-transcriptionally. Many genes, especially neuronal genes, have multiple different splicing events, promoters, and/or polyadenylation sites. Post-transcriptional coordination is in the infancy of being studied and the functional consequences of this coupling at the single cell level has yet to be explored. Here we show, mec-2 coordination of alternative transcription start …

She emphasized that her experience was more historical than personal memory. She also shares personal stories of friends and family affected by the Holocaust. Sandy reflects on how the influence of her parents' honesty, kindness, and activism, the idealism of post-WWII democracy, and the importance of seeking evidence over belief shaped her …

Finite-Difference Time-Domain Simulation For Interpreting Regional Infrasound Arrivals And Estimating Propagation Path Effects, Jesse Howard

Earth Sciences Theses and Dissertations

New full-wave infrasound simulation tools were developed based on an optimized finite-difference time-domain solution of 2D axisymmetric linear and nonlinear fluid dynamic equations. These tools were applied to estimate propagation path effects and enhance phase interpretation for regional infrasound arrivals. Middle-atmosphere full-wave predictions for a range of idealized atmospheres show that shadow zone arrivals and fast and slow arrival pair components from multiple ducts can be delineated using a combination of full-wave modeling and geometrical acoustics. Relationships between phase velocity and effective sound profile were established for each arrival type. Implications for source characterization were that amplitude and spectrum variation …

Childhood Maltreatment And The Conserved Transcriptional Response To Adversity (Ctra): The Protective Roles Of Social Support From Romantic Partners, Family, And Friends In Adulthood, Sumaiyah U. Syed

Psychology Theses and Dissertations

Childhood maltreatment is associated with an increased risk of chronic disease and mortality in adulthood, with chronic inflammation emerging as a key pathway. However, findings in the literature are mixed: while some studies associate childhood maltreatment with heightened inflammation, others report no such link. Given the prevalence of childhood maltreatment, identifying protective factors in adulthood is crucial. Social support during childhood has been shown to buffer the effects of early life stress on immune function, yet the role of social support from various sources in adulthood remains unclear. The current study examined the association between childhood maltreatment and the expression …

Is Helping You Good For Me? Associations With Giving Capitalization Support And The Moderating Role Of Closeness, Samuel Molli

Psychology Theses and Dissertations

When good things happen, people often seek to share their joy with others. This act of sharing one’s positive experience with another is termed capitalization. Receiving capitalization support has been linked to multiple positive outcomes, especially when one receives an engaged and positive response. However, the outcomes related to giving engaged and positive responses to another’s capitalization are less clear. The current study sought to understand how responding positively to a romantic partner’s capitalization event is associated with the support provider’s momentary mood and interpersonal closeness. Additionally, the current study examined how the support provider’s trait-level closeness with their …

Repurposing The Land Of An East Los Angeles Church: The Discovery Of How Small And Medium Sized Churches Through Affordable Housing Can Combat Homelessness While Revitalizing Its Nonprofit Status, Donald Cook, Donald Ray Cook Ii

Doctor of Ministry Projects and Theses

In order to live, humans need to sleep; therefore, sleep is mandatory, but unfortunately, everyone does not have the option of sleeping inside. Subsequently, many homeless encampments have developed in many countries. The perspective that people have often determines their response to homelessness. One person might view a homeless encampment as a problem that needs to be removed while someone else can view it as an opportunity to serve the least of these. Not only did Adam and Eve experience homelessness when removed from the Garden of Eden, but Mary, Joseph, and Jesus experienced first-hand the rollercoaster of inadequate housing. …

Phase Transitions In The Co-Doped Heusler Alloy Ni2mn1−Xcoxga, Jing Han Chen, Tej Poudel Chhetri, Nathaniel Wrobel, Xiaojian Bai, David P. Young, Igor Dubenko, Saikat Talapatra, Naushad Ali, Shane Stadler

Faculty Publications

The phase transitions of a series of Co-doped Heusler alloys, Ni 2 Mn 1 − x Co x Ga ( 0 ⩽ x ⩽ 0.2 ), were investigated experimentally using the magnetization measurements, x-ray diffraction, and calorimetric measurements up to their respective melting points. With increasing Co concentration, the structural transition temperatures, Curie temperatures, and melting points, were observed to increase, while the order-disorder transition temperatures decreased. Temperature-dependent x-ray diffraction experiments revealed two different crystal structures in the low-temperature martensite phase for different Co concentrations. However, above their respective structural transitions, both low-temperature crystal structures transformed into the L2 1 …
