Molecular investigations of subgroup I geminiviruses
The diversity of Subgroup I geminiviruses causing streak disease in maize, sugarcane, and indigenous wild grasses was investigated. The virus. isolates studied originated from maize (several southern African isolates), two sugarcane cultivars (from Natal province, South Africa, and from Mauritius), …

Problematic eating behaviors among college women: suggesting a subgroup
… for more and extensive research of the at-risk subgroup of sorority women are discussed.

Single-Model Any-Subgroup Equivariance via Symmetric Positional Encodings
… the full Sₙ symmetry group, we can obtain subgroup G ⊆ Sₙ equivariance by using a symmetry-breaking input that is G-symmetric. Under mild conditions, the resultant network is only G-equivariant. But finding an input with automorphism group exactly G is computationally hard, which can be …

Gradient Subgroup Scanning for Distributionally and Outlier Robust Models
… accuracy on average but low accuracy on certain subgroups, especially when there exist spurious correlations between the input data and label. Previous approaches for reducing the discrepancy between average and worst-group accuracies typically require expensive known subgroup annotations for …

The evolution of prezygotic reproductive isolation in the Drosophila pseudoobscura subgroup
… reproductive isolation in the D. pseudoobscura subgroup. I begin by evaluating how the evolution of female preferences and male sexual characters lead to reinforcement between Drosophila pseudoobscura and its congener D. persimils. In particular, I will evaluate two alternative hypotheses; …

Approaches to Fines Production in the Walloons Subgroup, Surat Basin, Queensland
… in coal seam gas wells in the Walloons Subgroup of the Surat Basin, southeast Queensland, Eastern Australia. Fines production can be critical in causing erosion in downhole pumping equipment and disruption to surface facilities. The Surat Basin has, in places, exceptional coal …

Functional studies on receptor-type protein tyrosine phosphatases of the R3 subgroup
… protein tyrosine phosphatases (RPTPs) of the R3subgroup play key roles in the immune, vascular and nervous system. They are characterised by an extracellular domain (ECD), comprised of multiple FNIII-like repeats, a transmembrane domain and a single intracellular phosphatase domain. Although …

Dynamics of free group automorphisms and a subgroup alternative for out(fn)
… we prove several structural theorems for subgroups of Out(F_N).

Functional and physiological discovery in the mannonate dehydratase subgroup of the enolase superfamily
… characterization of the mannonate dehydratase subgroup (ManD) of the enolase superfamily (ENS). The outcome affirms the dangers of homology-based annotations while discovering novel metabolic pathways. Furthermore, the experimental verification of these pathways (in vitro and in vivo) has …

Professional interpreters as a subgroup of highly proficient bilinguals: a Dynamic Systems Theory (DST) approach
Professional interpreters are often described as “exceptional” bilinguals, however, there is very little information in the literature about the particulars of this kind of bilingual proficiency, or the conditions and life experiences resulting in its development (Valdes and Angelelli, 2003). …

Sedimentology, provenance, and salt-sediment interaction in the Ediacaran Pound subgroup, Flinders Ranges, South Australia
Much of our understanding of the sedimentary character and stratigraphic architecture of subsurface sedimentary deposits is derived from field-based studies of similar depositional systems exposed in outcrop. In South Australia, excellent surface exposures in the Neoproterozoic-Cambrian Adelaide …

Causal inference for complex data: randomization inference for treatment effect heterogeneity, network outcomes, and subgroup specific effects
This dissertation presents three new methodologies for analyzing randomized controlled trials using the researcher controlled randomization mechanism as the basis for inference. The first method extends inference for the ``attributable effect'', the total of the difference of outcomes if the …

The role and essence of pilot trials and subgroup analysis in cardiovascular research: the IMPI trial experience
… definitive trials. It then focuses on how subgroup analysis can be used as an essential statistical tool for fully understanding clinical trial results and can be used to unearth non-apparent results in RCT. In the thesis, we highlight the need for accurate, systematic and complete …
