Enhanced plasma wave spectral asymmetries
… these enhanced plasma waves. Power and frequency asymmetries are detected between spectra of enhanced plasma waves propagating parallel and antiparallel to the radar line-of-sight at the altitude of observation. The power spectra are corrected for the antenna gain frequency dependence. The power …

Asymmetries in extragalactic radio sources
The purpose of this thesis was to explore computationally the three dimensional hydrodynamics of extragalactic radio jets. This entailed putting together a large number of numerical tools before such simulations could be performed. The thesis was structured to be a set of papers, each addressing a …

Brain-behavioural olfactory asymmetries in Apoidea
… Over groups of individuals, brain-behavioural asymmetries might present a direction in the occurrence of the bias (the majority of the individuals showing the same direction at the population level) that has been mathematically demonstrated to be an evolutionarily stable strategy in social …

Information Asymmetries, Transparency, and Monetary Policy
Information asymmetries seem to play an important role in monetary economics. We consider three forms of information transmission which can be used to alleviate these information asymmetries. First, if information is verifiable or the publication of information is in the central bank's interest, it …

Reindexing and some asymmetries in Universal Grammar
… namely, antecedent government, by examining some asymmetries, such as subject/object asymmetries, superiority effects, and that-trace effects. I claim that the Reindexing Principle is a parameter, which accounts for the differences among languages with regard to the above typological asymmetries, …

Visual search asymmetries in complex geophysical displays
… information. The use of visual search asymmetries (Treisman & Souther, 1985) in the design of display iconography might be an effective technique for prioritizing important information in such displays, but only if the asymmetry persists in the presence of clutter. The present …

Asymmetries in Presupposition Projection: Processing and Acquisition
In this dissertation, I aim to provide novel evidence to shed light on the projection problem of presuppositions. The focus is on identifying the underlying patterns of how presuppositions project out of two binary connectives, if and or, by disentangling semantic presuppositions from additional …

Transverse spin asymmetries in neutral strange particle production
… poorly understood. Significant transverse spin asymmetries in the production of hadrons have been observed over many years, and are related to both the transverse polarisation of quarks in a transversely polarised proton and to the spin dependence of orbital motion. These asymmetries are of …

Exploring HI asymmetries in real and simulated galaxies
… studies, has recently been used to quantify asymmetries in the H i images of galaxies. This is useful since H i disks typically extend further than the stellar disks and are more sensitive to distortions from interactions. Asymmetries can also manifest in the 1D spectral domain, distorting …

Tidal velocity asymmetries and bedload transport in shallow embayments
Tidally forced circulation can cause a net near-bed transport of sediment when the tidal velocity is asymmetric about a zero mean (flood or ebb dominant) and the transport rate is nonlinearly related to velocity. The relationship between elevation and velocity is elucidated here to enable one to …

The Semantic Basis for Subject/object Asymmetries in English
However, there are sentences which show an asymmetry between the temporal location of the subject in the eventuality and other constituents in the sentence, such as Aunt May resembled Sally, where Aunt May is dead and Sally is alive. The state of resembling cannot be contained wholly in the past …

Barkhausen Noise Studies: Pinning Field Statistics and Time-Asymmetries
Finally, returning to pinning field statistics, a comparison of the length-scales involved in avalanche size distributions, temporal Barkhausen power spectra, and spatial pinning field power spectra illustrates that the most recent justification for the statistics of the effective pinning field is …

Compression effects, perceptual asymmetries, and the grammar of timing
… perception. The first experiment demonstrates asymmetries in timing between consonants and vowels, which depend on the manner of the consonant. The second experiment shows that these asymmetries in speech production are mirrored by perceptual asymmetries among consonants with different manner …

The articulatory basis of positional asymmetries in phonological acquisition
Child phonological processes that lack counterparts in adult phonological typology have long posed a problem for formal modeling of phonological acquisition. This dissertation investigates child-specific processes with a focus on the phenomenon of neutralization in strong position, whereby children …

SME Lending - Asymmetries and Opportunities in the Brazilian Market
Small and medium-sized enterprises (SMEs) play a crucial role in a global society. They account for a significant portion of employment and contribute to innovation and economic growth both in developed and emerging economies. Strength SMEs have a direct impact on job creation and stimulate …
