A Review Of Plant–Microbe Interactions In The Rhizosphere And The Role Of Root Exudates In Microbiome Engineering, Anagha Wankhade, Emma Wilkinson, David W. Britt, Amita Kaundal

Biological Engineering Student Research

Microbial interactions within the rhizosphere are fundamental to plant health, influencing nutrient availability, stress tolerance, and pathogen resistance. Beneficial microbes, such as plant growth-promoting microbes (PGPMs), including bacteria and mycorrhizal fungi, enhance plant resilience through mechanisms like nutrient solubilization, phytohormone production, and pathogen suppression via antimicrobial compounds and siderophores. Root exudates, composed of sugars, organic acids, and secondary metabolites, act as chemoattractants that shape the rhizosphere microbiome by recruiting beneficial microbes. Microbial metabolites can, in turn, modulate plant physiology and exudate profiles, thereby reinforcing mutualistic interactions. Stress conditions alter exudate composition, enabling plants to attract specific microbes that aid in …

Descriptive Sensory Analysis Of Gluten-Containing And Gluten-Free Chocolate Chip Cookies Available In The Marketplace, Eniola Ola, Victoria J. Hogan, Han-Seok Seo

Food Science Faculty Publications and Presentations

Limited research has systematically compared the detailed sensory profiles of commercially available gluten-containing (C) and gluten-free (F) cookies using trained panelists. This study aimed to develop a comprehensive sensory lexicon for C and F chocolate chip cookies and identify key sensory attributes that differentiate them. Seven professionally trained panelists created a lexicon of 33 attributes spanning aroma, flavor, basic taste, texture, and residual property. Using this lexicon, a descriptive analysis was conducted on 12 C and 12 F cookie samples. Multivariate analysis of variance revealed significant differences between the two groups across the 33 sensory attributes (p < 0.05). A mixed model analysis showed that C cookies had higher intensities of chocolate-related and sweet aroma complex notes, while F cookies exhibited stronger nutty, artificial, and off-note flavors. In terms of texture, F cookies were higher in toothpack and powdery mouthcoat, while C cookies displayed more melt-in-mouth characteristics. Principal component analysis and agglomerative hierarchical clustering revealed three distinct clusters of test samples within both crispy and chewy cookie types, with some F cookies closely aligning with C profiles. These findings, along with the developed lexicon, provide a valuable foundation for enhancing the sensory appeal and quality of gluten-free chocolate chip cookies.

Coarse-Graining Spiking Reservoirs: Reducing Reservoir Size While Preserving Critical Dynamics, Tucker X. Mastin, Christof Teuscher

Northeast Journal of Complex Systems (NEJCS)

We propose an extension of renormalization into the domain of spiking neural networks, thereby providing a novel framework for coarse-graining neural networks without disrupting their critical properties. The proposed coarse-graining technique merges neurons and synaptic connections based on a graph-theoretic distance derived from synaptic weight strength and is configured to effectively prune the reservoir size while preserving the scale-free spiking dynamics indicative of criticality. Criticality in spiking neural networks may provide information-theoretic advantages by optimizing information processing and sensitivity to input. Using time-series prediction benchmarks, we demonstrate that networks operating at criticality exhibit up to 32% higher prediction accuracy before …

Doctoral Dissertations and Projects

The following quantitative correlational study investigated the effects of eTMS on individuals with pharmacoresistant sleep disorders using a qEEG. This research measures the dimensions of anxiety, depression and quality of life (QoL) as it relates to untreated secondary diagnosis. Additionally, this research examines the activity level of the dorsolateral prefrontal cortex in relation to eTMS treatments. It was found that correlation with anxiety (rs = -.466, p < .001), depression (rs = -0.556, p < 0.001), quality of life (rs = -.436, p < .001), and sleep disturbances (rs = -0.452, p < 0.001), have a statistically significant negative correlation with dlPFC activity level. Finally, it was found that eTMS does have a statistically significant relationship with sleep disturbances as well as anxiety, depression and general quality of life (U (195) = 4647, p = .971). This is important to the field of neuroscience as it provided a more precise form of individualized neuromodulation through the use of a uncommon type of transcranial magnetic stimulation.

Analysis Of Synaptotagmin Isoforms In Lßt2 Gonadotrophs, Caitlin Vahl

Undergraduate Theses, Capstones, and Recitals

The anterior pituitary is comprised of five cell types which secrete regulatory hormones into the bloodstream. Specifically, gonadotrophs synthesize and release sex hormones follicle-stimulating hormone (FSH) and luteinizing hormone (LH) in response to gonadotropin-releasing hormone (GnRH). GnRH signals from the hypothalamus regulate the differential secretion of LH and FSH from the anterior pituitary. Exocytosis of FSH and LH from dense core vesicles (DCVs) occurs in response to an intracellular calcium signal, sensed by the synaptotagmins proteins. Various isoforms of synaptotagmins exist and each isoform has varying affinity for calcium, causing calcium-regulated exocytosis to be finely controlled. Because LH and FSH …
