It is challenging to test machine learning (ML) applications, which are intended to learn properties of data sets where the correct answers are not already known. In the absence of a test oracle, one approach to testing these applications is to use metamorphic testing, in which properties of the application are exploited to define transformation functions on the input, such that the new output ...

southern Omineca Belt, fieldwork was undertaken in 1987 to examine the geology of the Eagle River fault in the eastem Shuswap Highland. The Eagle River fault is a west-sidedown low-angle normal fault that juxtaposes low to mediumgrade metasedimentary and metavolcanic rocks of the Paleozoic Mount Ida Group atop high-grade gneisses of the Shuswap metamorphic complex (Figure 1-4-1 inset). Regional...

Machine Learning algorithms have provided core functionality to many application domains - such as bioinformatics, computational linguistics, etc. However, it is difficult to detect faults in such applications because often there is no "test oracle" to verify the correctness of the computed outputs. To help address the software quality, in this paper we present a technique for testing the imple...

Crystallographic preferred orientation (CPO) and the associated seismic anisotropy of serpentinites are important factors for understanding tectonic settings involving hydrated Earth´s mantle, example, at slow-spreading mid-ocean ridges. CPO lizardite magnetite in low-grade metamorphic from Atlantis Massif oceanic core complex (Mid-Atlantic Ridge, 30°N) were determined using synchrotron high en...

To better understand serotonergic modulation of air breathing during bullfrog development, we measured changes in fictive lung ventilation frequency associated with focal stimulation of the rostral region of the medullary Raphé neurons. Electrical (3 to 33 Hz) and chemical (glutamate microinjections; 0.5 mol l(-1), 0.3-10 nl) activation of Raphé neurons was performed in brainstem preparations f...

OF THESIS AXOLOTL PAEDOMORPHOSIS: A COMPARISON OF JUVENILE, METAMORPHIC, AND PAEDOMORPHIC AMBYSTOMA MEXICANUM BRAIN GENE TRANSCRIPTION Unlike many amphibians, the paedomorphic axolotl (Ambystoma mexicanum) rarely undergoes external morphological changes indicative of metamorphosis. However, internally, some axolotl tissues undergo cryptic metamorphic changes. A previous study examined interspec...

We prove the hyperbolicity of the complement of five lines in general position in an almost complex projective plane, answering a question by S. Ivashkovich.
