Hopf Algebras Of Prime Dimension In Positive Characteristic, Siu Hung Ng, Xingting Wang

Faculty Publications

We prove that a Hopf algebra of prime dimension p over an algebraically closed field, whose characteristic is equal to p, is either a group algebra or a restricted universal enveloping algebra. Moreover, we show that any Hopf algebra of prime dimension p over a field of characteristic q > 0 is commutative and cocommutative when q = 2 or p < 4q. This problem remains open in positive characteristic when 2 < q < p/4.

Dehydration in rodents induces anorexia. In humans however, the role of dehydration in energy intake is controversial. This study investigated the effect of extreme fluid restriction on acute energy intake during and after exercise-induced dehydration. Eight physically active participants performed two exercise sessions to induce dehydration. After the exercise, the men were allowed to either rehydrate for 2 h or were maintained in a hypohydrated state, in a randomized manner. After 2 h, they were given cereal bars ad libitum for 1 h. Blood and saliva samples of the participants were collected before the exercise session, after the exercise session, …

Broad-Scale Habitat Use By Fledgling Black-Capped Vireo, Marisa T. Martinez, Ashley M. Long, Heather A. Mathewson, Michael L. Morrison

Faculty Publications

Knowledge of avian habitat associations during the postfledging stage is lacking for most songbirds, which limits the ability to develop and implement management plans that address the full life cycle of birds. The Black-capped Vireo (Vireo atricapilla; hereafter vireo) is a Neotropical migratory songbird that breeds in early to mid-successional vegetation but has been documented using late-successional vegetation. We used data collected in 2013 and 2014 to determine the spatial distribution of vireo fledglings in relation to the availability of woodland cover in central Texas. We found that woodland cover was used less often than it was available in the …

Faculty Publications

The 2007 European Union Floods Directive encouraged member nations to pursue a more integrated view of flood risks and management strategies, taking into account social vulnerabilities of residents. To date, most flood-risk analyses conducted by the Dutch government have focused on physical risk. This study utilizes fine-scale data to construct a social vulnerability index for 147 districts of the Dutch province of Zeeland, located in the Southwestern Delta and the scene of widespread devastation following the 1953 North Sea Flood. Factor analysis of 25 indicators of social vulnerability selected from related research in Europe and the United States results in …

Ground-State Shape Evolution In Er And Yb Isotopes, Xin Guan, Haichao Zhao, Feng Pan, Jerry P. Draayer

Faculty Publications

The ground-state shape (phase) evolution in Er and Yb isotopes is manifested in the axially deformed Nilsson mean-field plus extended pairing model. The energy ratio R 0 2 ⁺ /2 1 ⁺ , the odd-even mass differences, the ground-state occupation probabilities of valence nucleon pairs with different angular momenta and the information entropy are calculated. It is shown from these quantities as functions of the quadrupole deformation parameter and the overall pairing interaction strength that the ground-state shape (phase) evolution is mainly driven by the pairing interaction and less affected by the quadrupole deformation, which thus provides a possible origin …

Maize Responsiveness To Azospirillum Brasilense: Insights Into Genetic Control, Heterosis And Genomic Prediction, Miriam Suzane Vidotti, Filipe Inácio Matias, Filipe Couto Alves, Paulino Pérez Rodríguez, Gregório Alvarado Beltran, Juan Burguenõ, José Crossa, Roberto Fritsche-Neto

Faculty Publications

Several studies have shown differences in the abilities of maize genotypes to facilitate or impede Azospirillum brasilense colonization and to receive benefits from this association. Hence, our aim was to study the genetic control, heterosis effect and the prediction accuracy of the shoot and root traits of maize in response to A. brasilense. For that, we evaluated 118 hybrids under two contrasting scenarios: I) N stress (control) and ii) N stress plus A. brasilense inoculation. The diallel analyses were performed using mixed model equations, and the genomic prediction models accounted for the general and specific combining ability (GCA and SCA, …

Faculty Publications

Background—Treatments for adolescents with overweight/obesity demonstrate mixed success, which may be due to a lack of consideration for developmental changes during this period. Potential developmental differences in weight loss motivations, weight maintenance behaviors, and the role of parents in these efforts were examined in a sample of successful adolescent weight losers.

Methods—Participants enrolled in the Adolescent Weight Control Registry (n = 49) self-reported demographic information and weight history, reasons for weight loss and weight control, weight loss approach and weight maintenance strategies, and perceived parental involvement with weight loss. Associations between age at weight loss initiation and the aforementioned factors …

An Examination Into The Defining Characteristics Of Flexible Solar Aircraft Configurations Through Optimization, Taylor Mcdonnell, Andrew Ning

Faculty Publications

This paper examines the defining characteristics of various solar aircraft configurations through gradient-based multidisciplinary design optimization. We first present a general gradient-based solar aircraft optimization framework which accounts for nonlinear aeroelastic effects resulting from structural flexibility. We then apply this framework to several discrete SR- HALE aircraft geometric, structural, and propulsion system configuration choices to determine the defining characteristics of each configuration choice.

Bounds On Vacuum-Orthogonal Lorentz And Cpt Violation From Radiative Corrections, Brett Altschul

Faculty Publications

Certain forms of Lorentz violation in the photon sector are difficult to bound directly, since they are “vacuum orthogonal”—meaning they do not change the solutions of the equations of motion in vacuum. However, these very same terms have a unique tendency to contribute large radiative corrections to effects in other sectors. Making use of this, we set bounds on four previously unconstrained d = 5 photon operators at the 10 − 25 – 10 − 31 GeV − 1 levels.

Becoming Animal: Karma And The Animal Realm Envisioned Through An Early Yogacara Lens, Daniel Malinowski Stuart

Faculty Publications

In an early discourse from the Saṃyuttanikāya, the Buddha states: “I do not see any other order of living beings so diversified as those in the animal realm. Even those beings in the animal realm have been diversified by the mind, yet the mind is even more diverse than those beings in the animal realm.” This paper explores how this key early Buddhist idea gets elaborated in various layers of Buddhist discourse during a millennium of historical development. I focus in particular on a middle period Buddhist sūtra, the Saddharmasmṛtyupasthānasūtra, which serves as a bridge between early Buddhist theories of …

Hydrodynamic Modeling Coupled With Long-Term Field Data Provide Evidence For Suppression Of Phytoplankton By Invasive Clams And Freshwater Exports In The San Francisco Estuary, Bruce G. Hammock

Faculty Publications

The San Francisco Estuary (California, USA) had abundant pelagic fish in the late 1960s, but has few pelagic fish today. A primary cause for this decline in fish is thought to be a trophic cascade, triggered by declining phytoplankton. Here, we describe the changes in pelagic community structure of the San Francisco Estuary. Then, we examine whether changes in hydrodynamics due to freshwater exports, which increased exponentially beginning in 1967, in addition to the 1986 invasion by the clam Potamocorbula amurensis, explain the phytoplankton loss. Hydrodynamic variables were reconstructed back to 1956 using statistical models fit to, and cross-validated against, …

Grain-Size Affected Mechanical Response And Deformation Behavior In Microscale Reverse Extrusion, Bin Zhang, Mohammad Dodaran, Shahrior Ahmed, Shuai Shao, W. J. Meng, K. J. Juul, K. L. Nielsen

Faculty Publications

The continuing demand on device miniaturization has motivated the interest in micro metal forming technologies for manufacturing metal parts with sub-mm characteristic dimensions. In this work, axisymmetric reverse extrusion experiments were conducted on Cu 110 and Al 1100 alloy rod specimens with widely varying initial grain sizes, achieved through equal channel angular pressing (ECAP) and post annealing. Accompanying crystal plasticity finite element (CPFE) simulations were carried out. At a characteristic extrusion dimension (CED) of ∼100 µm, defined by the sidewall thickness of the extruded cup-shaped structures, the deformation characteristics of the reverse extrusion process were investigated. Specifically, the characteristic plastic …

Combined Molecular Dynamics And Phase Field Simulation Investigations Of Crystal-Melt Interfacial Properties And Dendritic Solidification Of Highly Undercooled Titanium, Sepideh Kavousi, Brian R. Novak, Mohsen Asle Zaeem, Dorel Moldovan

Faculty Publications

The effects of kinetic and capillary anisotropies on crystal morphology and growth rate during solidification of titanium are studied using atomistically-informed phase field simulations. Molecular dynamics (MD) is employed to calculate the anisotropic kinetic coefficient and crystal-melt interface free energy using the free solidification and capillary methods. The phase field simulation results for solidification velocity and interface temperature are in quantitative good agreement with experimental and analytical data for undercoolings below 150 K. As the role of interface kinetic effects increases with undercooling the use of a modified phase field model allowed the extension of its quantitative prediction capability to …

Energetic, Structural And Mechanical Properties Of Terraced Interfaces, M. Dodaran, J. Wang, Y. Chen, W. J. Meng, S. Shao

Faculty Publications

Taking the well-understood Cu-Ni {111} semi-coherent interface as a prototype, we demonstrate an important, yet long-been-overlooked, size effect on the properties of terraced interfaces — i.e. the facet length scale effect. Interfacial facets are considered as super interface disconnections (SIDs). We then studied the SID's size effect on the energy, structure, and mechanical response of terraced interfaces by using atomistic simulations and defect theories. We found that the specific facet energy — therefore the specific energy of the terraced interface — exhibits a periodic change with the SID's size. The periodic change is associated with the quantized transitions in their …

Fairness-Aware Energy-Efficient Resource Allocation In D2d Communication Networks, Shengjie Guo, Xiangwei Zhou, Sa Xiao, Mingxuan Sun

Faculty Publications

In this paper, the energy efficiency in a cellular network with device-to-device communications is studied from user fairness perspective. A mixed-integer max-min optimization problem is formulated, in which both mode selection and resource allocation are considered. Since the optimal solution requires exhaustive search, which is NP-hard, two suboptimal methods are derived. First, a Lagrangian decomposition-based method is proposed to jointly solve subcarrier assignment and power allocation with integer constraint relaxation under different modes. To further reduce the computational complexity, a low-complexity decomposition (LCD) method is derived. A novel mode selection scheme, a subcarrier assignment scheme, a power allocation scheme, and …
