Entoloma salmoneum
Get PDFSaprobic; growing in moss under conifers and sometimes hardwoods, often growing on decaying conifer logs covered with moss. This specimen was collected in mossy leaf-litter under conifer trees. This species can be found through summer and fall and is widely distributed throughout Northeast America and Canada. This species grows alone or scattered. It has a distinctive pointed cap and vibrant orange-yellow color. Its cap is 1-3 cm wide with a bright salmon-orange color that fades to dirty yellow-orange with age and is sticky when young. This species’ gills are attached to the stem, distant, often short, and have the same color as the cap when it is young. Similar to the gills and cap, this species’ stem is salmon colored, although often a darker or dirtier shade. The stem is 4-10 cm long, 2 mm thick, hollow, and fragile. At the base of its stem, this species has a white to soft orange basal mycelium that connects to surrounding moss or leaf-litter. Additionally, this species has no distinctive odor or taste, is KOH negative, and has a pink spore print. This species is also known as Entoloma quadratum, Rhodophyllus lactifluus, Inocephalus quadratus and Nolanea quadrata as there is debate over this taxa and overlapping similarities (Kuo 2014). In order to properly understand how these species overlap and are morphologically similar, molecular research is needed. Having a singular species thought to include others from different genera is unusual and should be subject to further investigation. This may suggest that the phylogenetic relationships between these genera and species is convoluted and inaccurate.

Leotia lubrica
Get PDFWidely distributed in North America; Saprobic; growing gregariously under hardwoods and conifers; often found growing in moss, occasionally found on rotting wood; late spring through fall in colder climates. DESCRIPTION: Cap 1-1 ½ cm; convex with irregular lobes and undulations, with the margin rolled inward; bald; sticky; yellow to light ochre. Stem 1-2 cm long; ½ cm wide; bald; sticky. Flesh gelatinous when fresh; odorless. This species has been observed in Argentina, and throughout South and Central America. (Lorenzo and Messuti 2013). Research conducted in Central America indicates this species forms arbutoid mycorrhiza, a type of ericoid mycorrhiza distinguished by penetration of host cortical cells, with a tropical woody plant Comarostaphylis arbutoides. (Kühdorf et al. 2015) Analyses of the three morphologically defined species, L. lubrica, L. viscosa, and L. atrovirens showed none of them to be monophyletic which indicates that there may be more genetic variation among Leotia than is commonly recognized.

Assessment of Oxytocin-Receptor Modulation of Social Recognition Following Adolescent Ethanol Exposure
Get PDFAdolescent alcohol consumption is prevalent in the United States. Studies report that adolescents ages 12 to 20 consume alcohol at and exceed binge levels, which is defined as 4 drinks for women and 5 for men over two hours. Rodent-model studies considering adolescent intermittent alcohol (ethanol) exposure (AIE) have shown that consumption results in long-term deficits in memory, cognition, social and nonsocial anxiety, and other behaviors into adulthood in part due to the vulnerability of late-developing brain regions such as the frontal cortex, amygdala, and hippocampus. Recent developments have indicated that oxytocin receptor activity is diminished following AIE and that restoration of oxytocin activity can reverse atypical social anxiety, but it is unclear whether oxytocin modulates other AIE-related behaviors. In the current study, Sprague Dawley rats were exposed to ethanol 4 mg/kg during early adolescence from postnatal days (P) 25-45 and then went undisturbed until adulthood (P70-75). During adulthood, a social recognition task was performed to assess short-term memory. We predict that social recognition impairment should be evident in AIE animals compared to non-AIE control subjects. Additionally, as oxytocin receptors are found in multiple brain regions involved in social recognition, we further predict that administering the oxytocin receptor agonist (WAY-267464) will reduce the effects of social recognition impairment in AIE animals. Data is currently being collected and analyzed. Pending results will be presented.https://orb.binghamton.edu/research_days_posters_2021/1069/thumbnail.jp
Student Environmental Conservation and Awareness on College Campuses
Get PDFIn the midst of a climate crisis, it’s crucial to question how our younger generations view their role in environmental conservation, activism and awareness, and how they implement greener values into their day-to-day lives. This research analyzes student perspectives on their role in environmentalism on their college campuses and if it’s changed through the Covid-19 pandemic. Additionally, this research questions how universities and higher education play a role in shaping these views and ideals among their student body. Through a series of interviews and surveys dispersed to students at both Binghamton University and SUNY Stony Brook, I will draw comparative conclusions regarding student views on their role in making a difference through environmental awareness and activism. This includes both day-to-day actions as well as involvement in campus initiatives, education, and promotion of these ideals. I will also investigate the impact that universities themselves have on these views through promotion of greener ideals, support for student led initiatives, and other influences. My results will demonstrate the level of awareness of environmental issues among college students, and if they have a willingness to address them and work towards change through both university and student led initiatives. My results could show if and how the Covid-19 pandemic has influenced student action in recent months. Overall, this study is important in analyzing how my generation values our planet and how they work towards and promote more eco-friendly values and lifestyles on their campuses.https://orb.binghamton.edu/research_days_posters_2021/1079/thumbnail.jp
ClusterCat Algorithm: Supervised Subcategory K-Means Clustering
Get PDFK-means is an unsupervised clustering algorithm that tries to partition a given dataset into k clusters, where each point belongs to only one cluster. The point of this algorithm is to classify data into different categories which may help provide structure to otherwise complex data sets. Although K-means is simple to implement and generally effective in categorizing data, there is no guarantee that objects will be correctly grouped together. This poster proposes a new supervised clustering algorithm, ClusterCat, that utilizes K-means. Supervised classification algorithms select training items and categorize test points based on that training. Unsupervised classification algorithms generate clusters based on feature characteristics. ClusterCat is unique as it is a supervised algorithm that leverages an unsupervised technique. ClusterCat first divides the dataset based on known category labels (supervised categorization) and then runs the K-means algorithm on each category (unsupervised categorization). This process creates smaller subcategories which are then used to make classification decisions. A test point is placed in a subcategory based on feature similarity, which allows the overarching category membership to be deduced. ClusterCat shows promise to improve classification decisions and could help demystify complex data structures.https://orb.binghamton.edu/research_days_posters_2021/1080/thumbnail.jp
Optimization of Growth Parameters of WS2 Synthesis: Effects on Crystallinity and Optical Properties
Get PDFSemiconducting transition metal dichalcogenides (TMDs) are a specific class of two-dimensional (2D) materials with the chemical structure MX2. A transition metal, represented by “M”, is positioned between two chalcogen layers, represented by “X2”. The specific system of interest in this research is tungsten disulfide, WS2, which has applications in optoelectronics. This work focuses on synthesis of WS2 via chemical vapor deposition (CVD) using a liquid precursor. In this process, argon gas carries gas phase sulfur through a quartz tube. The Si substrate that has been plasma cleaned and spin coated with the liquid precursor is placed in the center of the tube furnace, downstream from the sulfur. The sulfur is usually heated to about 250 °C, while the furnace is heating to around 800 °C. The influence of growth parameters (such as growth time, gas flow rate, and temperature) on the crystallinity of these atomically thin layers is also studied. Raman spectroscopy and photoluminescence (PL) are non-invasive techniques that are commonly used to analyze TMDs. The epitaxial relation between both crystals will be studied along with variation in number of layers and optical fingerprint of the WS2. The choice of substrate is expected to change the properties of the sample. Thus, future work will investigate the growth of WS2 and Fe-WS2 on highly ordered pyrolytic graphite (HOPG).https://orb.binghamton.edu/research_days_posters_2021/1007/thumbnail.jp
