Climate Change Is Driving Greening Trend Whereas Tree Cover Is Declining In The Western Himalaya Of Pakistan, Arshad Mahmood Khan, Nadia Khalid

Journal of Bioresource Management

Recent studies suggest that two factors including climate change (especially precipitation) and human land use management (HLUM) are primarily driving greening trend around the world. However, studies targeting the impact of both factors on different vegetation layers (i.e. herbs, shrubs and tree layers) are lacking. This study hypothesize that precipitation relatively influence the under-storey vegetation cover more quickly, and HLUM (say afforestation/reforestation, deforestation) is more important towards top-storey layer. To investigate this, 13 randomly selected permanent stations in the wild natural west Himalayan coniferous forests of Sudhan Gali, Pakistan were explored from 2000-2016 to collect vegetation health data by two …

Enhanced Grazing Management Assessment Using Drone-Based Lidar Measurements, V. W. Temu, W. C. Hession, P. Sforza, H. Wang

IGC Proceedings (1977-2023)

Globally, there is an urgent need of research-based technologies for small ruminant producers to benefit from rapidly growing market demands for ruminant meat and related food products from forage-based operations. However, effective forage-based animal production requires a rapid assessment, and monitoring of grazing management needs to adjust stocking rates and/or spatial animal distribution in a timely manner. Applicability of unmanned aerial vehicles (drones) for grazing management offers opportunities to rapidly estimate biomass build-ups, ground coverage, and monitor animal behaviour. The reliability of drone-based laser scanning (DLS) for monitoring warm-season grass responses to simulated grazing intensities was assessed at Virginia State …

Ecorestore: Decision Support System To Restore The Productivity Of Degraded Rangelands In Southern Africa, Klaus Kellner, Dirk Pretorius, C. Marais

IGC Proceedings (1977-2023)

Land degradation is a multifaceted problem that affects the agricultural productivity of land due to a loss of vegetation cover and can often be ascribed to bush encroachment in savanna and grassland rangelands. Bush encroachment entails the increase in abundance and density of indigenous and alien woody vegetation (i.e. shrub thickening), which has a negative impact on the tree-grass ratio, biodiversity, as well as on a range of ecosystem services that affect the well-being of land users, often causing an increase in poverty and the introduction of non-sustainable land management practices, especially in arid- and semi-arid regions mostly affected by …

John Bull's Stinginess In East Florida, Claude C. Sturgill

Florida Historical Quarterly

There is no doubt that in the British imperial heaven the scheme of things after 1763 called for the Floridas to become to the American South what Lake George and Quebec were to the American North. A brief study of British regiments in St. Augustine in the eighteenth century demonstrates how military units were assigned to East Florida. Unfortunately the article brings into print once again, although this time through omission, what is proving to be the myth of the financial plight of the Floridas during the period of English occupation. Professor Charles Loch Mowat’s writings also accepted the theory …

Claude Pepper And The Florida Canal Controversy, 1939-1943, Alexander R. Stoensen

Florida Historical Quarterly

The dream of a waterway across Florida from the Atlantic Ocean to the Gulf of Mexico long has captured the imagination. In 1595 Spanish cartographers depicted one across the peninsula, a mistake assumed correct for nearly 200 years. During the British period in Florida, the royal government conducted a survey to determine if such a route existed, and in 1788 the United States army produced a sketch map of the area, although by that time it was clear no watercourse existed. Later, Thomas Jefferson’s administration exhibited the first high-level American interest in the construction of a waterway—an interest which has …

An Enhanced Predictive Hierarchical Power Management Framework For Islanded Microgrids, Jimiao Zhang, Jie Li, Ning Wang, Ben Wu

Henry M. Rowan College of Engineering Departmental Research

This paper proposes an enhanced three-layer predictive hierarchical power management framework for secure and economic operation of islanded microgrids. The tertiary control, guaranteeing the microgrid economic operation, is built upon the semi-definite programming-based AC optimal power flow model, which periodically sends power references to secondary control. To mitigate uncertainties arising from renewable generations and loads, a centralized linear model predictive control (MPC) controller is proposed and implemented for secondary control. The MPC controller can effectively regulate the microgrid system frequency by closely tracking reference signals from the tertiary controller with low computational complexity. Droop-based primary controllers are implemented to coordinate …

In Situ Characterization Of Tensile Behavior Of Laser Rapid Solidified Al–Si Heterogeneous Microstructures, Bingqiang Wei, Wenqian Wu, Dongyue Xie, Huai-Hsun Lien, Metin Kayitmazbatir, Amit Misra, Jian Wang

Department of Mechanical and Materials Engineering: Faculty Publications

Heterogeneous Al–Si microstructure comprising of sub-micron-scale Al dendrites and nanoscale Al–Si fibrous eutectic was fabricated by processing as-cast Al-20wt.%Si alloy using laser rapid solidification. In situ tension tests explored high tensile strength ( ∼ 600 MPa) and ductility ( ∼ 10%) and high strain hardening rate ( ∼ 7 GPa). Microstructural characterization revealed the plastic co[1]deformation mechanisms between soft Al dendrites and hard nanoscale Al–Si eutectic. The progression of plasticity in nanoscale Al–Si eutectic with increasing applied strain is accommodated by dislocation plasticity in the nano-Al channels and cracking Si nanofibers. The propagation of nano-cracks is suppressed by surrounding Al, …

Congruity Of Virtual Reality In-Game Advertising, Joshua M. Lupinek, Jinhee Yoo, Eugene A. Ohu, Eric Bownlee

Department of Hospitality and Tourism Faculty Scholarship and Creative Works

With virtual reality (VR) video game users beginning to see beta advertisements within game play, this conceptual article adds a needed digital and interactive marketing research foundation to the new construct of VR in-game advertising (IGA) activation. New consumer VR technology continues to disrupt traditional media as a $7.7 billion USD industry, that is expected to reach $57.55 billion by 2027. As such, marketing researchers must continue to evolve and understand the interdisciplinary VR research evolution as many VR users are likely to view IGA as intrusive. IGA and VR are not new constructs, but IGA within VR is unique …

Biophysical Evaluation Of Rhesus Macaque Fc Gamma Receptors Reveals Similar Igg Fc Glycoform Preferences To Human Receptors, Andrew R. Crowley, Nana Yaw Osei-Owusu, Gillian Dekkers, Wenda Gao, Manfred Wuhrer, Diogo M. Magnani, Keith A. Reimann, Seth H. Pincus, Gestur Vidarsson, Margaret E. Ackerman

Dartmouth Scholarship

Rhesus macaques are a common non-human primate model used in the evaluation of human monoclonal antibodies, molecules whose effector functions depend on a conserved N-linked glycan in the Fc region. This carbohydrate is a target of glycoengineering efforts aimed at altering antibody effector function by modulating the affinity of Fcγ receptors. For example, a reduction in the overall core fucose content is one such strategy that can increase antibody-mediated cellular cytotoxicity by increasing Fc-FcγRIIIa affinity. While the position of the Fc glycan is conserved in macaques, differences in the frequency of glycoforms and the use of an alternate monosaccharide in …

Luminescence Complementation Technology For The Identification Of Myc:Trrap Inhibitors, Edmond J. Feris, John W. Hinds, Michael D. Cole

Dartmouth Scholarship

Mechanism-based targeted therapies have exhibited remarkable success in treating otherwise untreatable or unresectable cancers. Novel targeted therapies that correct dysregulated transcriptional programs in cancer are an unmet medical need. The transcription factor MYC is the most frequently amplified gene in human cancer and is overexpressed because of mutations in an array of oncogenic signaling pathways. The fact that many cancer cells cannot survive without MYC - a phenomenon termed "MYC addiction" - provides a compelling case for the development of MYC-specific targeted therapies. We propose a new strategy to inhibit MYC function by disrupting its essential interaction with TRRAP using …

Zero-Bias Deep Neural Network For Quickest Rf Signal Surveillance, Yongxin Liu, Jian Wang, Dahai Liu, Houbing Song, Yingjie Chen, Shuteng Niu

Publications

The Internet of Things (IoT) is reshaping modern society by allowing a decent number of RF devices to connect and share information through RF channels. However, such an open nature also brings obstacles to surveillance. For alleviation, a surveillance oracle, or a cognitive communication entity needs to identify and confirm the appearance of known or unknown signal sources in real-time. In this paper, we provide a deep learning framework for RF signal surveillance. Specifically, we jointly integrate the Deep Neural Networks (DNNs) and Quickest Detection (QD) to form a sequential signal surveillance scheme. We first analyze the latent space characteristic …
