Summary & Discussion On United Nations Preliminary Report On Ai: Benefits And Harms Of Artificial Intelligence For Civil Society, Angie Holzer
Journal of Nonprofit Innovation
In July 2026, the United Nations' newly formed Independent International Scientific Panel on Artificial Intelligence released its first Preliminary Report, offering the first global, scientific assessment of AI's capabilities, risks, and impacts. This article examines the report's findings through the lens of civil society, organizing the Panel's evidence around three questions of direct relevance to nonprofit leaders and researchers: how rapidly AI capability is advancing, who controls its development, and where its benefits and harms are concentrated. Drawing on the Panel's data across societal applications, economic implications, human rights and information integrity, cultural flourishing and child safety, and AI governance, …
Effects Of Scion And Rootstock On Arbuscular Mycorrhizal Symbiosis And Spore Communities In Vitis Vinifera, Nicholas Vergara, Stephen Bentivenga
Effects Of Scion And Rootstock On Arbuscular Mycorrhizal Symbiosis And Spore Communities In Vitis Vinifera, Nicholas Vergara, Stephen Bentivenga
STEM Student Research Symposium Posters
Arbuscular mycorrhizal fungi (AMF) are obligate root symbionts that extend host nutrient uptake in exchange for photosynthate. Nearly all commercial wine grapes (Vitis vinifera) are grafted onto American rootstocks selected for phylloxera resistance, drought tolerance, and vigor, meaning the root system interfacing with soil fungi is genetically distinct from the fruiting scion. Whether root system origin shapes AMF association remains poorly resolved, particularly in sandy, low-fertility soils. We compared AMF colonization and spore communities across four rootstock–scion combinations (Cabernet Franc and Merlot scions, own-rooted and riparian rootstock) at William Heritage® Winery in Mullica Hill, NJ. Fine roots were cleared, stained, …

Comparison Of Arbuscular Mycorrhizal Fungal Colonization And Spore Communities Between Clover-Dominated Cover Crop And Restored Native Grass Systems, Nicholas Vergara, Stephen Bentivenga
STEM Student Research Symposium Posters
Arbuscular mycorrhizal fungi (AMF) are obligate root symbionts that extend host nutrient uptake in exchange for photosynthate. Restored native grasslands and cover-cropped fields represent contrasting management strategies applied to former conventional farmland, differing in both tillage frequency and plant diversity, yet how these strategies shape AMF association in sandy, low-fertility soils remains largely understudied. We compared AMF colonization and spore communities between two adjacent sites converted approximately three years prior at the Bishop Farmstead, Southampton Township, NJ: a restored grassland dominated by Panicum virgatum and an agricultural field under white and red clover cover (Trifolium repens, T. pratense). Fine roots …

Oncogenic E-Cadherin-Dependent Metastasis And Potential Therapeutic Interventions, Madison K. Duenas, Anjela Anand, Paige Cano, Ralph Boccia, Mary Alpaugh
STEM Student Research Symposium Posters
Oncogenic E-cadherin-dependent metastasis is a paradoxical mechanism of cancer progression whereby E-cadherin, a cell-to-cell adhesion protein that normally suppresses tumor invasion, instead promotes the formation of cohesive cell tumor clusters that collectively invade surrounding tissues and metastasize. This phenomenon has been extensively studied using inflammatory breast cancer (IBC) models, including the MARY-X xenograft and SUM149 cell line, while comparisons with other breast cancer models such as MDA-MB-231 continue to provide insight into E-cadherin-independent metastatic mechanisms. This project reviews recent literature investigating the molecular mechanisms behind it and evaluates emerging therapeutic strategies targeting E-cadherin-associated cellular pathways. Laboratory techniques, including spheroid generation …

Biomass’ pyrolysis process is responsible for producing the biochar charcoal, this process does not incorporate the oxygen, and it is utilized as a soil enhancer for each one of the carbon sequestration, and soil health prospects. Biochar can be defined as a stabilized solid which is enriched with carbon and could remain in the soil for extended period of time. Biochar has been studied as a way of carbon sequestration, and it might be a way used for handling climate change and global warming. It happens due to the processes that are associated with pyrogenic carbon capturing and storages. This …

Engineering and Technology Journal
Plastic waste has become one of the humanities and the ecosystem balance serious environmental Challenges. Furthermore, it is the primary source of plastic pollution because it is inexpensive, widely available, and frequently discarded. Using various waste materials and side fractions as part of wood-plastic composites is one way to promote the circular economy (WPC). Several environmental benefits can be realized by using recycled plastic, including extending the usable life of plastic, reducing waste, contributing to the development of trash recycling, and preventing resource depletion. One of the most efficient recycling processes is glycolysis; the (PET) is depolymerized by ethylene glycol …

Signaling Load Reduction In 5g Network And Beyond, Mohammed Waheed, Azzad Saeed, Thanaa Abd
Engineering and Technology Journal
A huge traffic flow in the next generation network is anticipated due to the rising in number of users and the new services that need low end-to-end latency causing a large signaling load on the Core Network (CN). In order to mitigate this issue, many revolutionary architectures have been proposed to reduce this burden such as Cloud Radio Access Network (C-RAN). In this paper, a new C-RAN distributed core network architecture has been proposed by splitting some CN functions and grouping them into one location with Base Band Units (BBUs). As a measure of testing the proposed architectures and by …

Detection Of Confusion Behavior Using A Facial Expression Based On Different Classification Algorithms, Fatima I. Yasser, Bassam H. Abd, Saad M. Abbas
Engineering and Technology Journal
Confusion detection systems (CDSs) that need Noninvasive, mobile, and cost-effective methods use facial expressions as a technique to detect confusion. In previous works, the technology that the system used represents a major gap between this proposed CDS and other systems. This CDS depends on the Facial Action Coding System (FACS) that is used to extract facial features. The FACS shows the motion of the facial muscles represented by Action Units (AUs); the movement is represented with one facial muscle or more. Seven AUs are used as possible markers for detecting confusion that has been implemented in the form of a …
