Understanding Behavioral And Representational Divergences Of Humans And Machines, Thomas Lasman Botch

Dartmouth College Ph.D Dissertations

Human behavior and cognition are strikingly variable: people differ from one another in their preferences and abilities, and even from themselves across situations. Yet this diversity arises from common neural machinery shaped by the complex environments humans inhabit. A central objective of cognitive neuroscience is to understand how this varied experience emerges from interactions between brains, agents, and environments. In this dissertation, I argue that comparing behavior and neural computation across humans, artificial systems, and contexts is essential for understanding the flexibility of human cognition. Across three chapters, I use this comparative approach to examine how the rich, multimodal contexts …

Nobiletin Improves Organismal Health By Regulating Circadian Rhythms : Absorption, Mechanisms, And Delivery Strategies, Zhang Mengling, Han Lingxian, Zhao Chan, Liang Zengenni

Food and Machinery

Nobiletin, a hexamethoxyflavone unique to citrus peels, exhibits activity in regulating circadian rhythms. Characterized by a low molecular weight, it can cross the blood-brain barrier and demonstrates various biological functions, including antioxidant, anti-inflammatory, cardiovascular protective, and anticancer effects. However, limitations such as its low water solubility, high crystallinity, and poor stability hinder its nutritional and functional performance in food applications. Therefore, this review summarizes the in vivo absorption of nobiletin, its penetration through the blood-brain barrier, and the biotransformation processes of its active metabolites. Furthermore, this review discusses the regulatory effects on the central clock and peripheral clocks, as well …

Strongly Confined Bismuth Antimonide Quantum Dots, Min Khadka, Rajendra Subedi, Qiaohui Zhou, Xin Lu, Joelin A. Agyei-Mensah, Miguel José-YacamáN, Guillaume Lang, Etienne Herth, Gregory Guisbiers

Faculty Scholarship

Bismuth antimonide (Bi1–xSbx) has emerged as a highly promising material for quantum applications due to its complex band structure. In this study, spherical Bi1–xSbx quantum dots (QDs), with a diameter of around 8 ± 2 nm, were successfully synthesized by pulsed laser ablation in liquids. The energy bandgap was determined at 2.02 ± 0.27 eV, which is significantly higher than the bulk value (∼0.025 eV). The strong confinement nature of the dots was confirmed by the Raman peak shifts. The chemical composition of the Bi1–xSbx QDs was measured to be around 77 ± 2 at. % of Bi and 23 …

Development And Characterization Of Sulfur-Based Concrete From Industrial Waste By-Products, Vasilia Numan Rabah Alkhaldi

Thesis/ Dissertation Defenses

Portland cement (PC) is a significant player in the construction industry, which is one of the largest global carbon footprint sectors, contributing approximately 8% of total anthropogenic CO₂ emissions worldwide. In arid and developing countries such as the UAE, the negative impacts of PC are amplified by the piling of industrial wastes, and hence there is an urgent need to develop efficient and cost-effective waste management solutions. This dissertation reports on the design and characterization of a novel sulfur-based concrete made from locally available industrial waste materials, with an emphasis on improving the performance and durability of the material as …
