Hybrid Ai-Quantum Computational Framework For Efficient Eddy Current Repulsion Force Simulation, Z Zhang, Y Ryu, Wh Li, Jiayin Y Wang

School of Computing Faculty Scholarship and Creative Works

Eddy current repulsion forces are essential to the operation of magnetic levitation, electromagnetic braking, and wireless power transfer systems, yet their accurate simulation remains computationally intensive due to the complexity of Maxwell's equations and the need for fine-resolution meshing in transient, high-frequency domains. This paper presents a hybrid AI-Quantum computational framework that accelerates eddy current simulation by combining adaptive meshing via Physics-Informed Neural Networks for adaptive meshing, quantum-assisted solvers (Harrow Hassidim-Lloyd algorithm and Variational Quantum Eigensolver) for selected finite element subdomains, and GPU-accelerated finite element methods, and reduced-order modeling based on Proper Orthogonal Decomposition and Quantum Autoencoders. The framework selectively …

Coupled Ferroelectricity And Phonon Chirality, Xiang-Bin Han, Cong Yang, Rui Sun, Xiaotong Zhang, Thuc Mai, Zhengze Xu, Aryan Jouneghaninaseri, Xiaoning Jiang, Rahul Rao, Yi Xia, Multople Additional Authors

Mechanical and Materials Engineering Faculty Publications and Presentations

Recognizing the coupling between ferroelectricity and chirality in optically active ferroelectrics opens a route for manipulating chirality via ferroelectricity under an external electric field, enabling control over chirality-dependent quantum states. Here, we report the experimental demonstration of the coupling between ferroelectricity and phonon chirality in the molecular ferroelectric triglycine sulfate. By electrically switching the crystal chirality, we achieve reversible and device-compatible control of phonon chirality, as revealed by in situ time-resolved magneto-optical Kerr effect measurements. The Kerr rotation reverses with electric-field switching, while phonon chirality vanishes in the paraelectric phase and is tunable in the racemic ferroelectric state. Furthermore, density …

Summer Dormancy In Italian Populations Of Dactylis Glomerata L., F Lorenzetti, A Panella, E Falistocco

IGC Proceedings (1977-2023)

Mediterranean types of perennial grasses are winter-growing and summer-dormant, while central and northern European types arc winter-dormant and aummer•growing. Dormancy severely limits the annual production and largely determines the seasonal distribution pattern of the perennial grass. Summer dormancy wa• studied in 81 Italian populations of Dac!)llit glomtTata. L. collected from north (48°N) to south (38°N) on the Italian pt:ninaula. Dormancy was measured at Perugia (43°O5'N) on 60 plant.'i for each population. The percentage of summer-dormant plants was negatively correlated with the mean score for summer growth (r = -0.75**). The results distinguish three main groups of populations with increasing levels …

Growth And Development Of Two Echinochloa Millet Species In A Warm Temperate Climate, D K. Muldoon

IGC Proceedings (1977-2023)

Most summer forage crops fall into either the sorghum or the millet species group. Included in the millet group are two species, Echinochloa utilis and Echinochloa frumentacea, commonly known as Japanese barnyard millet and Indian barnyard millet, respectively. These species have a negligible HCN potential and higher nutritive value than Sorghum species. However, they generally flower early, yield less than forage sorghum , and lack vigor in regrowth. In this study the pattern of growth and development of two Echinochloa millets was examined as part of a larger program of improving the production of these forage species. E. utilis …

IGC Proceedings (1977-2023)

Kenyan and Ethiopian natural grazing Ian.cl. support more than 20% of the cattle population of the African continent. Many of the natural pastures of these countries are severely overgrazed, as unfavorable grazing conditions prevail for over half the year. Objectives of adaptation trials were to evaluate and identify introduced or indigenous forage and fodder species or ecotypes having genetic potential for high production of digestible dry matter for direct pasture and range improvement and for future use in breeding programs. Over 4,000 indigenous and 3,000 introduced ecotypes were evaluated for 24 vegetative characters in six ecological regions between 1971 and …

Collections Of Western Wheatgrass And Blue Grama And Associated Nematode Genera In The Western Dakotas, R E. Barker, J D. Berdahl, J M. Krupinsky, E T. Jacobson

IGC Proceedings (1977-2023)

Western wheatgrass (Agropyron smithii Rydb.) and blue grama (Bouteloua gracilis[Willd. ex H.B.K.J Lag. ex Griffiths) are widely distributed throughout the U.S.A. They arc two of the predominant native grasses in rangelands in the northern Great Plains. Because suitable cultivars are not always available for reseeding disturbed areas, we collected plants of the two species and evaluated phenotypic variability to determine potential for breeding improvement. We also sampled the nematode popula­tion associated with the collections. Sampling sites were systematically chosen by establishing a grid pattern 19 .3 km apart in the western halves of North Dakota and South Dakota. …

Productivity Of Forage Legumes On Rice-Paddy Walls In Northeast Thailand, R G. Gutteridge

IGC Proceedings (1977-2023)

Rice stubble left standing in paddy fields after rice harvest is the major source of forage for livestock in the dry season in northeast Thailand. Although the quantity of thi5 1tubble is generally not limiting, its quality as a forage is very low, and substantial live-weight losses in livestock usually occur by the end of the dry season. A trial was conducted to evaluate a range of forage legumes that could be grown on rice-paddy walls to supplement rice stubble as a dry-season feed. Seven legumes were planted at two sites in villages close to Khon Kaen in northeast Thailand. …

Development Of Gama Medic {Medicago Rugosa Desr.) As An Annual Leguminous Species For Dryland Farming Systems In Southern Australia, E J. Crawford

IGC Proceedings (1977-2023)

Annual medics (Medicago spp.) are the basic legume for nitrogen fixation in the alkaline soils of southern Australia. Not all in­dividual species are well adapted to all soil types, one difficult soil being the highly alkaline clay loam where annual rainfall is less than 500 mm. The first gama medic (M. rugosa) cultivar, Paragosa, was well adapted to the clay-loam soil type but proved to be susceptible to germination after summer thunderstorms, and seedlings died in the following drought. Many gama medic accessions were then grown in an attempt to select a genotype capable of maintaining seedcoat impermeability during …

Evolution Of Selection Techniques In Breeding For Bloat-Safe Alfalfa, B P. Goplen, R E. Howarth, G L. Lees, W Majak, J P. Fay, K J. Cheng

IGC Proceedings (1977-2023)

This report summarizes the Canadian breeding program to develop a bloat-safe alfalfa (Medicago sativa L.). This program has experienced an evolution of selection methods in attempting to identify bloat-safe alfalfa genotypes. In chronological order, the methods involved selection for fraction I (18S) protein, soluble proteins, foam volume, tannins (flavolans), saponins, initial rate of digestion (IRD), sonication, purified enzymes, gas production, and leaching. Although soluble herbage protein is correlated with the occurrence of pasture bloat, we have experienced slow progress in a selection program to reduce soluble-protein concentration in alfalfa. We have found that foam volume is not correlated with …

Effective Selection For Tolerance To Grass-Killing Herbicides In Perennial Ryegrass (Lolium Perenne L.), C E. Wright, J S. Faulkner

IGC Proceedings (1977-2023)

The aim of grassland reseeding is to establish a high-quality sward of improved herbage cultivars. To obtain the maximum value from the improved sward, weed invasion should be prevented. Herbicides are the main tool available. There are many herbicides for selectively controlling dicotyledonous, but not graminaceous, weeds. The control of graminaceous weeds would be possible in swards of grass cultivars selected for tolerance to grass-killing herbicides. Two cycles of recurrent selection for glyphosate tolerance in Lolium perenne L. were carried out by spraying large seedling populations with critical dosages in the greenhouse and intercrossing the survivors. It was found that …
