Improvement Of The Fault Tolerance In Iot Based Positioning Systems By Applying For Redundancy In The Controller Layer, Nawzad K. Al-Salihi

Baghdad Science Journal

In recent years, the positioning applications of Internet-of-Things (IoT) based systems have grown increasingly popular, and are found to be useful in tracking the daily activities of children, the elderly and vehicle tracking. It can be argued that the data obtained from GPS based systems may contain error, hence taking these factors into account, the proposed method for this study is based on the application of IoT-based positioning and the replacement of using IoT instead of GPS. This cannot, however, be a reason for not using the GPS, and in order to enhance the reliability, a parallel combination of the …

Arbitrating Copyright Disputes In Egypt, Islam Mohamed

Maurer Theses and Dissertations

Egypt is witnessing increasing difficulty in implementing and practicing protectionist policies for intellectual property rights, which includes copyright as a fundamental element. Since the Egyptian judicial system is exclusively concerned with adjudicating all disputes, it has become increasingly burdened in recent decades due to this monopoly. As a result, the Egyptian judiciary is witnessing a significant slowdown in resolving conflicts and procedural obstacles which delay the restitution of Intellectual property rights to its owners. Thus, we believe that applying arbitration will contribute to resolving copyright disputes in advance on one hand and will encourage an attractive climate in such matters …

Background:

State health rankings, national nursing education reform, and increasing awareness of social injustices propelled a college of nursing to transform its strategic plan, infrastructure, and curriculum. The prevalence of social determinants of health (SDOH) in South Carolina indicates a need for the state's health workforce to understand the impact of SDOH and recognize strategies to address and ameliorate SDOH. With the paradigmatic integration of diversity, equity, and inclusion in nursing education, there is a need for programmatic and curricular integration of SDOH to increase awareness, foster understanding, and transform perspectives among nursing faculty, staff, and students.

Challenges For Estimating The Global Prevalence Of Micronutrient Deficiencies And Related Disease Burden: A Case Study Of The Global Burden Of Disease Study, Sonja Y. Hess, Alexander C. Mclain Ph.D., Edward A. Frongillo Jr. Ph.D., Ashkan Afshin, Nicholas J. Kassebaum, Saskia Jm Osendarp, Reed Atkin, Rahul Rawat, Kenneth H. Brown

Faculty Publications

Information on the prevalence of micronutrient deficiencies is needed to determine related disease burden; underpin evidence-based advocacy; and design, deliver, and monitor safe, effective interventions. Assessing the global prevalence of deficiency requires a valid micronutrient status biomarker with an appropriate cutoff to define deficiency and relevant data from representative surveys across multiple locations and years. The Global Burden of Disease Study includes prevalence estimates for iodine, iron, zinc, and vitamin A deficiencies, for which recommended biomarkers and appropriate deficiency cutoffs exist. Because representative survey data are lacking, only retinol concentration is used to model vitamin A deficiency, and proxy indicators …

Spatial Distribution Of Conspecific Genotypes Within Chimeras Of The Branching Coral Stylophora Pistillata, Gabriele Guerrini, Dor Shefy, Jacob Douek, Nadav Shashar, Tamar L. Goulet, Baruch Rinkevich

Faculty and Student Publications

Chimerism is a coalescence of conspecific genotypes. Although common in nature, fundamental knowledge, such as the spatial distribution of the genotypes within chimeras, is lacking. Hence, we investigated the spatial distribution of conspecific genotypes within the brooding coral Stylophora pistillata, a common species throughout the Indo-Pacific and Red Sea. From eight gravid colonies, we collected planula larvae that settled in aggregates, forming 2–3 partner chimeras. Coral chimeras grew in situ for up to 25 months. Nine chimeras (8 kin, 1 non-related genotypes) were sectioned into 7–17 fragments (6–26 polyps/fragment), and genotyped using eight microsatellite loci. The discrimination power of each …

Rcb Initiates Arabidopsis Thermomorphogenesis By Stabilizing The Thermoregulator Pif4 In The Daytime, Yongjian Qiu, Elise K. Pasoreck, Chan Yul Yoo, Jiangman He, He Wang, Abhishesh Bajracharya, Meina Li, Haley D. Larsen, Stacey Cheung, Meng Chen

Faculty and Student Publications

Daytime warm temperature elicits thermomorphogenesis in Arabidopsis by stabilizing the central thermoregulator PHYTOCHROME INTERACTING transcription FACTOR 4 (PIF4), whose degradation is otherwise promoted by the photoreceptor and thermosensor phytochrome B. PIF4 stabilization in the light requires a transcriptional activator, HEMERA (HMR), and is abrogated when HMR’s transactivation activity is impaired in hmr-22. Here, we report the identification of a hmr-22 suppressor mutant, rcb-101, which surprisingly carries an A275V mutation in REGULATOR OF CHLOROPLAST BIOGENESIS (RCB). rcb-101/hmr-22 restores thermoresponsive PIF4 accumulation and reverts the defects of hmr-22 in chloroplast biogenesis and photomorphogenesis. Strikingly, similar to hmr, the null rcb-10 mutant impedes …

Climate And Seasonality Drive The Richness And Composition Of Tropical Fungal Endophytes At A Landscape Scale, Shuzo Oita, Alicia Ibáñez, François Lutzoni, Jolanta Miadlikowska, József Geml, Louise A. Lewis, Erik F. Y. Hom, Ignazio Carbone, Jana M. U’Ren, A. Elizabeth Arnold

Faculty and Student Publications

Understanding how species-rich communities persist is a foundational question in ecology. In tropical forests, tree diversity is structured by edaphic factors, climate, and biotic interactions, with seasonality playing an essential role at landscape scales: wetter and less seasonal forests typically harbor higher tree diversity than more seasonal forests. We posited that the abiotic factors shaping tree diversity extend to hyperdiverse symbionts in leaves—fungal endophytes—that influence plant health, function, and resilience to stress. Through surveys in forests across Panama that considered climate, seasonality, and covarying biotic factors, we demonstrate that endophyte richness varies negatively with temperature seasonality. Endophyte community structure and …

Spatiotemporal Pattern Detection With Neuromorphic Circuits, Robert C. Ivans

Boise State University Theses and Dissertations

In this dissertation, neuromorphic circuits are used to implement spiking neural networks in order to detect spatiotemporal patterns. Unsupervised training and detection-by-design techniques were used to attain the appropriate connectomes and perform pattern detection.

Unsupervised training was performed by feeding random digital spikes with a repeating embedded spatiotemporal pattern to a spiking neural network composed of leaky integrate-and-fire neurons and memristor-R(t) element circuits which implement spike-timing-dependent plasticity learning rules.

Detection-by-design was achieved using neuromporphic circuits and digital logic gates. When detection-by-design was achieved using both neuromorphic circuits and digital logic gates, a network was created of spatiotemporal pattern detector circuits, …
