Biosystematic studies of selected Texas species of Dichanthelium (Poaceae)
(Texas A&M University. Libraries, 1977)A taxonomic study was made of two genera, Dichanthelium and Panicum, in order to justify the elevation of Dichanthelium to generic rank. A comparison of all published characters, all new character differences found by the ... -
A biosystematic study of the genus Erioneuron Nash (Poaceae, eragrostideae)
(Texas A&M University. Libraries, 1985)A biosystematic treatment was made of the New World genus Erioneuron. Materials for morphological, electrophoretic, anatomical, and cytological studies were collected from naturally occurring populations, and from herbarium ... -
A biosystematic study of the Muhlenbergia repens Complex (Poaceae)
(Texas A&M University. Libraries, 1985)A biosystematic treatment was made of the Muhlenbergia repens complex. Materials for morphological, anatomical, embryological, and cytological studies were collected from throughout the geographic region of this complex. ... -
A biosystematic study of the Schizachyrium scoparium complex
(Texas A&M University. Libraries, 1989)Population samples of Schizachyrium scoparium, collected from Texas (vars. divergens, frequens, littorals, and virile) and New Mexico (var. neomexicanum), and herbarium specimens (including type specimens of Andropogon ... -
The Bootstrap in Supervised Learning and its Applications in Genomics/Proteomics
(2012-07-16)The small-sample size issue is a prevalent problem in Genomics and Proteomics today. Bootstrap, a resampling method which aims at increasing the efficiency of data usage, is considered to be an effort to overcome the problem ... -
Characterization of aggregate shape properties using a computer automated system
(Texas A&M University, 2005-02-17)Shape, texture, and angularity are among the properties of aggregates that have a significant effect on the performance of hot-mix asphalt, hydraulic cement concrete, and unbound base and subbase layers. Consequently, ... -
Chromosomal variation in Peromyscus boylii
(Texas A&M University. Libraries, 1987)Karyotypic data are presented for a total of 723 individuals of Peromyscus boylii from Latin America. The range of karyotypic variation now documented in P. boylii (FN = 47-68) is greater than that known for any other ... -
Comparative valve morphology of selected species of Eunotia Ehr. (Bacillariophyceae)
(Texas A&M University. Libraries, 1981)The valve morphology of twenty four taxa of the genus Eunotia from Texas and Alaska was examined with the light and scanning electron microscopes with particular emphasis on the terminal nodules, raphe, hyaline areas, ... -
Criteria Combinations in the Personality Disorders: Challenges Associated with a Polythetic Diagnostic System
(2011-08-08)Converging research on the diagnostic criteria for personality disorders (PDs) reveals that most criteria have different psychometric properties. This finding is inconsistent with the DSM-IV-TR PD diagnostic system, which ... -
Cytogenetic and cytosystematic studies of the nucleous organizer regions of North American cyprinid fishes
(Texas A&M University. Libraries, 1987)Chromosomal NOR banding was used to assay the variability of chromosomal NORs within and among 49 species (380 specimens) of North American Cyprinidae. Considerable intra- and interspecific NOR variability was documented. ... -
Cytosystematics of the Peromyscus boylii species group with phylogenetic implications for the subgenus Peromyscus (Rodentia : Cricetidae)
(Texas A&M University. Libraries, 1986)A description and analysis of differentially stained (G- and C-banded) chromosomes is provided for 12 described taxa in the Peromyscus boylii species group. Consistent with other species of Peromyscus, all boylii group ... -
Early Anomaly Detection and Classification with Streaming Synchrophasor Data in Electric Energy Systems
(2015-11-24)The large-scale streaming data collected from the increasing deployed phasor measurement unit (PMU) devices poses significant difficulties for real-time data-driven analytics in power systems. This dissertation presents a ... -
Evaluating soil variability as related to landscape position using different statistical methods
(Texas A&M University. Libraries, 1989)The variability of selected upland soils in Brazos County, Texas was studied using a sampling design that consisted of a main grid with 121 points spaced 30 m apart, three subgrids within the main grid, each with 49 points ... -
Fault Detection and Diagnosis in Gene Regulatory Networks and Optimal Bayesian Classification of Metagenomic Data
(2017-04-25)It is well known that the molecular basis of many diseases, particularly cancer, resides in the loss of regulatory power in critical genomic pathways due to DNA mutations. We propose a methodology for model-based fault ... -
Genesis of soils and carbonate enriched horizons associated with soft limestones in Central Texas
(Texas A&M University. Libraries, 1986)Soils associated with soft Cretaceous limestones occupy more than 3 million hectares in Central Texas and are important to the state's agricultural rangelands. Most of these soils occupy moderately to strongly sloping ... -
Investigation for Genetic Determinants of Flexion Contractures and Contracted Foal Syndrome in Neonatal Thoroughbred Foals
(2014-09-04)Musculoskeletal disorders are one of the leading causes of morality in neonatal Thoroughbred foals. Contracted Foal Syndrome (CFS) has accounted for up to 48% of such disorders in foals submitted for necropsy according to ... -
