On the Cutting of Metals at the Small Scale: Size Effect, Friction and Plastic Instabilities
(2022-02-16)
The “size effect” phenomenon in metal cutting – the substantial increase of the specific cutting energy with the decreasing chip size – is systematically studied. An instrumented ultramicrotome is applied to achieve ...
Three Studies in High-Field MR Engineering: SAR Reduction Through Sequential RF Pulses, A System for B1+ Steering, and A Low-Complexity Multi-Nuclei Array Coil
(2022-04-13)
Recent years have seen great development in ultra-high-field (UHF) magnetic resonance imaging (MRI). In particular, the advantage of increased sensitivity available at UHF and the scan time acceleration enabled by parallel ...
Downhole Intelligence for Drilling Systems Using Supervised and Deep Reinforcement Learning Techniques
(2022-04-21)
Operational decision-making during drilling for hydrocarbons or geothermal energy is challenging due to the complex nature of the process. Many of the times, these decisions have to be taken with incomplete information at ...
Development of PSMA-Targeted Radiopharmaceuticals for Routine Clinical Applications
(2022-02-03)
Prostate cancer (PCa) is regarded one of the most prevalent cancer diagnoses amongst men in the United States and worldwide. Moreover, PCa is the second leading cause of cancer deaths in America. Prostate specific membrane ...
4C Seismic Shear Wave Source Mechanism Analysis, Modeling and Imaging in the Shallow Marine Environment of the Arabian Gulf
(2022-04-18)
Reservoirs in the Arabian Gulf, home to some of the world’s largest oil reserves, consist primarily of heterogeneous carbonate rocks and successfully recovering hydrocarbons from them is a challenge. With existing technologies, ...
Effects of Long-Term Agricultural Nitrogen Fertilization on Organic Carbon Cycling
(2022-05-03)
The maintenance and improvement of soil organic carbon (SOC) pools is crucial to global food and fiber production as well as the management of carbon (C) emissions. Because SOC and nitrogen (N) cycles are linked, the effects ...
Development and Application of Metal-Based Flame Retardants to Improve the Fire Safety of Materials
(2022-04-18)
Polymeric materials find ubiquitous applications in modern daily life. However, as a kind of hydrocarbon-based energy-dense material, most polymeric materials are highly flammable, which is a big threat to life and property ...
Multi-calibration Based Drift Compensation for Chemical Sensor Arrays
(2022-04-21)
Long-term application of chemical sensor arrays for continuous monitoring is challenging as a result of sensor aging and drift. A number of techniques have been proposed to compensate for drift, but the issue remains a ...
Highly Lewis Acidic Carbocations for The Generation of Reactive Main-Group and Transition Metal Cations and New Ligand Design
(2022-01-11)
The chemistry of Lewis-acidic cations has had a profound impact on both academic and industrial sciences. The study of carbocations in particular has been revolutionary in the petrochemical industry and has resulted in ...
College Readiness for Students Starts with Professor Readiness
(2022-04-06)
Developmental education, corequisites courses, student success, and professional development are words constantly echoed in higher education, particularly community colleges. Ultimately, the administration assumes faculty ...
