Copper Nanoparticles In-Situ Anchored On Nitrogen-Doped Carbon For High-Efficiency Oxygen Reduction Reaction Electrocatalyst, Hui-Fang Yuan, Yue Zhang, Xing-Wu Zhai, Li-Bing Hu, Gui-Xian Ge, Gang Wang, Feng Yu, Bin Dai

Journal of Electrochemistry

Compared with noble metal platinum (Pt)-based catalysts, inexpensive non-noble metal electrocatalysts have attracted extensive attention for oxygen reduction reaction (ORR). Herein, chitosan as a kind of biomass resource rich in nitrogen and carbon was used to prepare nitrogen-doped carbon (N-C) and N-C in-situ anchored by copper nanoparticles (Cu/N-C). The as-obtained N-C and Cu/N-C nanoparticles were successfully used as non-noble eletrocatalysts tested for ORR. Compared with the N-C, the Cu/N-C showed the high surface area of 607.3 m ²·g^-1 with the mean pore size of 2.5 nm and the pore volume of 0.40 cm³·g^{-1 …}

Walter Scott At 250, Alison Lumsden, Kirsty Archer-Thompson

Studies in Scottish Literature

This essay marking the 250th anniversary of Walter Scott's birth reflects on the current state of Scott studies, the scholarly directions in which it might develop, and ways in which the relevance of Scott’s work may be re-discovered and re-invigorated for contemporary audiences. In particular, it examines scholarly and critical attitudes to Scott's work over the past 50 years through papers given at the triennial international Scott conferences initiated in Edinburgh in 1971, alongside developments in public engagement at Abbotsford House and elsewhere during the 250th anniversary year.

Computational Methods For Comparative Analyses Of Discourses, Zachary Stine

Theses and Dissertations

An underexplored aspect of the abundant linguistic data available for computational analysis is the potential for conducting large-scale comparative analyses between different discourses as a more rigorous complement to existing methods. A significant obstacle in comparative studies is the requirement that a researcher distinguish between discursive distinctions that are superficial and those that reflect deeper, structural relationships between the discourses being compared. In this dissertation, I describe two methodologies for comparing discourses in terms of their underlying structures, drawing on distributional semantic models and information theory. These methodologies are explored within three case studies in which the discourses of several …

‘Co-Ainm Na Taca Seo An-Uiridh’: Dugald Macnicol’S Caribbean Lament For Argyll, Nigel Leask, Peadar Ó Muircheartaigh

Studies in Scottish Literature

This article examines a Gaelic song written in 1816 in St. Lucia by a Scottish Gaelic-speaking army officer from Argyll, Dugald MacNicol (1791-1844), sketching MacNicol's life and military career in the Caribbean, in the Royal West Indian Rangers and later in the 1st Royals (Royal Scots Regiment), placing the song in relation to other Gaelic poems of emigration and exile, and printing a newly-edited text of MacNicol's song alongside the authors' English translation.

Evaluating The Use Of The L1 In A French Language Classroom, Joyce Esther Hiaumiti Guidi

Theses and Dissertations

Researchers have explored how different balances of first language (L1) and target language (TL) use in a foreign language classroom impact students' fluency and proficiency in TL acquisition. Research has shown that the use of the L1 in a foreign language classroom is done in order to determine the most effective way to raise the proficiency of second language learners to the level that is expected within their classrooms (Lee & Muncie, 2006). The use of the L1 is not something that is uncommon, even in the highest levels of foreign language instruction, although some believe it could inhibit learner …

Methods For Learning A User’S Intent Based On Spatial Gestures, Mingguang Xu, Kai Shi, Ning Zhang

Defensive Publications Series

This publication describes methods for learning a user’s intent, when the user interacts with multiple computing devices, based on detected spatial gestures. The methods may utilize a machine-learned model with a reinforcement-learning framework trained to classify spatial gestures, user state information, and/or device state information detected during a device-to-device interaction, generate predictions relating to the intent of the user, and utilize the predictions to facilitate the device-to-device interaction.

Compact Gas Sensor Using Silicon-On-Insulator Loop-Terminated Mach–Zehnder Interferometer, Raghi S. El Shamy, Mohamed A. Swillam, Mohamed M. Elrayany, Alaa Sultan

Faculty Journal Articles

In this paper, we propose a compact optical gas sensor based on the widespread silicon-on-insulator (SOI) technology, operating in the near-infrared (NIR) region around the 1.55 µm wavelength. The sensor employs a loop-terminated Mach–Zehnder interferometer (LT-MZI) with a slot waveguide and a strip waveguide for the sensing arm and the reference arm, respectively. For the same arm length, the LT-MZI can achieve a detection limit two times lower than that of the conventional MZI. Different sensor components were designed, and the optimum dimensions were obtained using finite-difference eigenmode (FDE) and finite-difference time-domain (FDTD) solvers. With a sensing arm length of …

Development Of A Custom Tendon Explant Frame Compatible With Reflectance Quantitative Polarized Light Imaging, Matthew Riak, Lila Dickstein

Mechanical Engineering and Materials Science Independent Study

Tendons and ligaments are collagenous tissues in the body which attenuate load. Reflectance quantitative polarized light imaging (rQPLI) is being developed to combat some of the issues present in many of the current imaging modalities used to study tendons and ligaments. To establish its utility in continuous monitoring of tendon healing, rQPLI will be used to monitor a tendon explant defect over a four week period in both normal and super healer mice strains. In this study, we discuss fabrication of a custom frame built to exert a constant force on tendon explants for these imaging studies. Additionally, the frame …

Introduction Major depressive disorder (MDD) is a debilitating human health status characterized by mood swings and high suicidal attempts. Several studies have reported the role of neuroinflammation in MMD, yet the efficacy of natural drug substances on neuroinflammation-associated depression needs to be further investigated. The present study demonstrated the neuroprotective effects of Acetyl-L- carnitine (ALC) alone or in combination with caffeic acid phenethyl ester (CAPE) on lipopolysaccharide (LPS) induced neuro-inflammation, depression, and anxiety-like behavior. Material and methods Male Sprague Dawley (SD) rats were used to explore the relative effects of ALC and the mechanistic interplay of the peroxisome proliferator-activated receptors …

Machine Learning Based Critical Resource Allocation In Mixed-Traffic Cellular Networks, Mohamed Nomeir

Theses and Dissertations

The proliferation of cellular networks over the past two decades has encouraged the expansion of their use in many modern applications. These applications involve the use of data traffic of different quality of service (QoS) requirements. Some of these requirements are quite stringent such as in the case of critical Internet of Things (IoT) health care, military and homeland security applications. This situation resulted in imposing a variety of resource allocation requirements on the cellular network operation in a simultaneous manner.

In this thesis, we consider the challenging problem of mixed-traffic resource allocation, or scheduling, in cellular networks. We focus …

A Mathematical Model For Transport And Growth Of Microbes In Unsaturated Porous Soil, Harihar Khanal, Andrei Ludu, Ramesh Chandra Timsina, Kedar Nath Uprety

Publications

In this work, we develop a mathematical model for transport and growth of microbes by natural (rain) water infiltration and flow through unsaturated porous soil along the vertical direction under gravity and capillarity by coupling a system of advection diffusion equations (for concentration of microbes and their growth-limiting substrate) with the Richards equation. (e model takes into consideration several major physical, chemical, and biological mechanisms. (e resulting coupled system of PDEs together with their boundary conditions is highly nonlinear and complicated to solve analytically. We present both a partial analytic approach towards solving the nonlinear system and finding the main …
