A Global Assessment Of The Mixed Layer In Coastal Sediments And Implications For Carbon Storage, Shasha Song, Isaac R. Santos, Huaming Yu, Faming Wang, William C. Burnett, Thomas S. Bianchi, Junyu Dong, Ergang Lian, Bin Zhao, Lawrence Mayer, Qingzhen Yao, Zhigang Yu, Bochao Xu

Center for Coastal and Ocean Mapping

The sediment-water interface in the coastal ocean is a highly dynamic zone controlling biogeochemical fluxes of greenhouse gases, nutrients, and metals. Processes in the sediment mixed layer (SML) control the transfer and reactivity of both particulate and dissolved matter in coastal interfaces. Here we map the global distribution of the coastal SML based on excess 210Pb (210Pbex) profiles and then use a neural network model to upscale these observations. We show that highly dynamic regions such as large estuaries have thicker SMLs than most oceanic sediments. Organic carbon preservation and SMLs are inversely related as mixing stimulates oxidation in sediments …

Systematic Study On Carbon Emission Reduction Of Municipal Solid Waste Treatment, Jisheng Long, Hailiang Du, Xin Zou, Jingying Huang

Bulletin of Chinese Academy of Sciences (Chinese Version)

Under the context of China's carbon peak and carbon neutrality, the treatment of municipal solid waste (MSW) is facing new challenge to reduce carbon emission. This study suggests that significant carbon emission reduction and dual cycle of mass and energy can be realized, under the context of MSW classification, by the collaborative treatment of multi-source solid waste in Eco-Industrial Park. Results showed that in 2020, the incineration and landfilling of MSW in China reduced 5.18 million tons of CO2 emission, at the same year, 15 million tons of CO2 emission could have been reduced if the wet waste was treated …

Scholarly Articles in Law Reviews & Journals

Free-roaming domestic cats (i.e., cats that are owned or unowned and are considered ‘at large’) are globally distributed non-native species that have marked impacts on biodiversity and human health. Despite clear scientific evidence of these impacts, free-roaming cats are either unmanaged or managed using scientifically unsupported and ineffective approaches (e.g., trap-neuter-release [TNR]) in many jurisdictions around the world. A critical first initiative for effective, science-driven management of cats must be broader political and legislative recognition of free-roaming cats as a non-native, invasive species. Designating cats as invasive is important for developing and implementing science-based management plans, which should include efforts …

Writing Our Climate Future: A “Cli-Fi” Writing Process For Students In The Anthropocene, Shannon Falkner

New Jersey English Journal

Like Covid, climate change causes many students to feel afraid and powerless. By studying infographics on climate change, we can help students develop their 21st century literacy skills while educating them about climate change and its solutions. As students draw on that knowledge to write their own “cli-fi” stories, they practice their narrative writing skills and learn how fiction writers address real-world issues in their work. As a result, students come to understand the power of literature to make abstract world issues feel personalized and meaningful to readers and the power they have as writers to effect change.

Decorrelated Deep Neural Networks: Learning Bias Invariant & Scanner Independent Features, And Causal Relationships Using A Novel Deep Learning Methods Based On Distance Correlation, Pranita Patil

Dissertations and Theses

Advancements in deep learning or deep neural networks have made it possible to reach expert-level performance in a variety of applications, even in challenging situations. However, a central challenge in all deep learning, as well as machine learning applications, is dealing with its dependency on the quality of data which can be significantly impacted by biases, confounders, and irrelevant variations in data which leads to spurious relationships and erroneous decisions. The main purpose of this dissertation is to build a robust deep learning model which considers and mitigates these biases. Another challenge with the deep learning model is learning associations …

Knowledge of the three-dimensional movement patterns of elasmobranchs is vital to understand their ecological roles and exposure to anthropogenic pressures. To date, comparative studies among species at global scales have mostly focused on horizontal movements. Our study addresses the knowledge gap of vertical movements by compiling the first global synthesis of vertical habitat use by elasmobranchs from data obtained by deployment of 989 biotelemetry tags on 38 elasmobranch species. Elasmobranchs displayed high intra- and interspecific variability in vertical movement patterns. Substantial vertical overlap was observed for many epipelagic elasmobranchs, indicating an increased likelihood to display spatial overlap, biologically interact, and …

Lower ambient temperature (Ta) requires greater energy expenditure to sustain body temperature. However, effects of Ta on human energetics may be buffered by environmental modification and behavioral compensation. We used the IAEA DLW database for adults in the USA (n = 3213) to determine the effect of Ta (−10 to +30°C) on TEE, basal (BEE) and activity energy expenditure (AEE) and physical activity level (PAL). There were no significant relationships (p > 0.05) between maximum, minimum and average Ta and TEE, BEE, AEE and PAL. After adjustment for fat-free mass, fat mass and age, statistically significant (p < 0.01) relationships between TEE, BEE and Ta emerged in females but the effect sizes were not biologically meaningful. Temperatures inside buildings are regulated at 18–25°C independent of latitude. Hence, adults in the US modify their environments to keep TEE constant across a wide range of external ambient temperatures.

The Role Of Small Gtpases In Regulating Blood-Brain Barrier Mechanotransduction, Brandon Jude Deore

Theses and Dissertations

Fluid shear stress is an important mediator of vascular permeability, yet the molecular mechanisms underlying the effect of shear on the blood-brain barrier (BBB) have yet to be clarified in cerebral vasculature despite its importance for brain homeostasis.. Neurological symptoms including the formation of microclots, stroke, and other neurological pathologies associated with changes in cerebral blood flow are hallmarks of BBB dysfunction. The in vitro model used in this dissertation is compatible with real-time measurement of barrier function using a transendothelial electrical resistance as well as immunocytochemistry and dextran permeability assays. These experiments reveal that there is a threshold level …

Comparative Anatomical Study Of The Brachial Plexus Of Primates, Alison Leann Camero

Masters Theses

Old world monkeys, new world monkeys, and humans all originate from a common ancestor. Although humans and old world monkeys are phylogenetically more closely related, old world monkeys and new world monkeys have similar locomotion. A difference in muscle patterns exists between old world monkeys, new world monkeys, and humans. Different musculature may be due to differences in locomotive patterns and species-specific use of their forearms. Muscles in the forelimbs are innervated by the nerves of the brachial plexus. There are differences among the brachial plexuses of human and non-human primates as well as variability within the species.

A major obstacle to identifying improved treatments for pediatric low-grade brain tumors (gliomas) is the inability to reproducibly generate human xenografts. To surmount this barrier, we leveraged human induced pluripotent stem cell (hiPSC) engineering to generate low-grade gliomas (LGGs) harboring the two most common pediatric pilocytic astrocytoma-associated molecular alterations, NF1 loss and KIAA1549:BRAF fusion. Herein, we identified that hiPSC-derived neuroglial progenitor populations (neural progenitors, glial restricted progenitors and oligodendrocyte progenitors), but not terminally differentiated astrocytes, give rise to tumors retaining LGG histologic features for at least 6 months in vivo. Additionally, we demonstrated that hiPSC-LGG xenograft formation requires the absence …

Teaching Fisheries Bycatch: Exploring Economic And Behavioral Drivers Of Bycatch Through A Classroom Game, Mitch B. Priestley, J. Forrest Williams, Sahan Dissanayake

Economics Faculty Publications and Presentations

This paper presents a pedagogical exercise to explore the economics of price-based fisheries bycatch. In the exercise students experience the economic incentives that lead to bycatch due to highgrading; the discarding of low-value fish. We first discuss existing fisheries economics pedagogical activities and how our exercise is distinct. We then identify over forty economics, environmental studies, geography, management, and philosophy courses where the exercise could be played. Next, we describe the game and share results and student feedback. Finally, we provide discussion prompts and extensions to illustrate how incentives and policies can change fishing behavior to lead to sustainable fisheries.

Purdue University Libraries Open Access Publishing Fund

Cerebrospinal fluid (CSF) movement through the pathways within the central nervous system is of high significance for maintaining normal brain health and function. Low frequency hemodynamics and respiration have been shown to drive CSF in humans independently. Here, we hypothesize that CSF movement may be driven simultaneously (and in synchrony) by both mechanisms and study their independent and coupled effects on CSF movement using novel neck fMRI scans. Caudad CSF movement at the fourth ventricle and hemodynamics of the major neck blood vessels (internal carotid arteries and internal jugular veins) was measured from 11 young, healthy volunteers using novel neck …

Framing Trust In Artificial Intelligence (Ai) Ethics Communication: Analysis Of Ai Ethics Guiding Principles Through The Lens Of Framing Theory, Namrata Nagar

Theses

With the fast proliferation of Artificial Intelligence (AI) technologies in our society, several corporations, governments, research institutions, and NGOs have produced and published AI ethics guiding documents. These include principles, guidelines, frameworks, assessment lists, training modules, blogs, and principle-to-practice strategies. The priorities, focus, and articulation of these innumerable documents vary to different extents. Though they all aim and claim to ensure AI usage for the common good, the actual AI system outcomes in various social applications have invigorated ethical dilemmas and scholarly debates. This study presents the analysis of AI ethics principles and guidelines text published by three pioneers from …

Architecture Of Video Games: Potential Reference, Wael Mkaouar

Theses

The Architecture perspective / scale in video games has evolved throughout time to an extent that it is no longer a mere spatial visualization to host the game, but it has become an interaction medium between the player and the game. Architecture in recent video games played a fundamental role in bridging the gap between the real and the digital world. The analogy between these two is increasingly established through the representational immersion and the participation of the player in a highly realistic environment transforming the gaming experience into an entertaining and educational journey. The aim of this thesis is …

Method Optimization For The Determination Of Cannabinoids In Blood By Liquid Chromatography Tandem Mass Spectrometry (Lc-Ms/Ms), Kevin D. Carrera

Student Theses

Delta-9-tetrahydrocannabinol (THC) continues to be one of the most popular drugs in the USA. Along with THC, other cannabinoids such as cannabidiol (CBD), are on the rise due to an increase in medicinal usage as well as the passage of different legislations removing these products from their current schedule I status. Thus, an urgency exists to develop robust and sensitive analytical methods to determine cannabinoids, especially THC, CBD and metabolites, in biological samples. The purpose of this study was to investigate different analytical procedures to determine the best method to identify and quantify CBD, THC and their metabolites in whole …

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) Omicron variant of concern comprises several sublineages, with BA.2 and BA.2.12.1 having replaced the previously dominant BA.1 and with BA.4 and BA.5 increasing in prevalence worldwide. We show that the large number of Omicron sublineage spike mutations leads to enhanced angiotensin-converting enzyme 2 (ACE2) binding, reduced fusogenicity, and severe dampening of plasma neutralizing activity elicited by infection or seven clinical vaccines relative to the ancestral virus. Administration of a homologous or heterologous booster based on the Wuhan-Hu-1 spike sequence markedly increased neutralizing antibody titers and breadth against BA.1, BA.2, BA.2.12.1, BA.4, and …

Barriers And Facilitators To Exclusive Breastfeeding In Rural Pakistan: A Qualitative Exploratory Study, Atif Riaz, Shelina Bhamani, Sheraz Ahmed, Fayyaz Umrani, Sadaf Jakhro, Abdul Khaliq Qureshi, Syed Asad Ali

Department of Paediatrics and Child Health

Background: Exclusive breastfeeding (EBF) of children until six months of age is considered one of the most critical interventions in tackling childhood undernutrition. EBF rates are suboptimal in Pakistan, particularly in rural areas where child undernutrition is most prevalent. This study aimed to explore barriers to EBF in a rural context of Pakistan.
Methods: The study was conducted in the rural district Matiari of Sindh, Pakistan, during Jan-March 2020. We used a qualitative exploratory study design and conducted 36 focus group discussions (FGDs). Participants were purposively selected mothers who had not practiced EBF during their previous childbirth, their spouses and …

Natural Locus Coeruleus Dynamics During Feeding, Natale R Sciolino, Alexxai V Kravitz, Et Al

2020-Current year OA Pubs

Recent data demonstrate that noradrenergic neurons of the locus coeruleus (LC-NE) are required for fear-induced suppression of feeding, but the role of endogenous LC-NE activity in natural, homeostatic feeding remains unclear. Here, we found that LC-NE activity was suppressed during food consumption, and the magnitude of this neural response was attenuated as mice consumed more pellets throughout the session, suggesting that LC responses to food are modulated by satiety state. Visual-evoked LC-NE activity was also attenuated in sated mice, suggesting that satiety state modulates LC-NE encoding of multiple behavioral states. We also found that food intake could be attenuated by …
