This paper describes a new software-based registration and fusion of visible and thermal infrared (IR) image data for face recognition in challenging operating environments that involve illumination variations. The combined use of visible and thermal IR imaging sensors offers a viable means for improving the performance of face recognition techniques based(More)
The Program for Research on Social and Economic Dimensions of an Aging Population (SEDAP) is an interdisciplinary research program centred at McMaster University with co-investigators at seventeen other universities in Canada and abroad. The SEDAP Research Paper series provides a vehicle for distributing the results of studies undertaken by those associated(More)
Cell death and inflammation are ancient processes of fundamental biological importance in both normal physiology and pathology. This is evidenced by the profound conservation of mediators, with ancestral homologues identified from plants to humans, and the number of diseases driven by aberrant control of either process. Apoptosis is the most well-studied(More)
BACKGROUND Tracheostomy should be considered to replace endotracheal intubation in patients requiring prolonged mechanical ventilation (MV). However, the optimal timing for tracheostomy is still a topic of debate. The present study aimed to investigate whether early percutaneous dilational tracheostomy (PDT) can reduce duration of MV, and to further verify(More)
In this work, a nonsmooth multiobjective optimization problem involving generalized invexity with cone constraints and Applications (for short, (MOP)) is considered. The Kuhn-Tucker necessary and sufficient conditions for (MOP) are established by using a generalized alternative theorem of Craven and Yang. The relationship between weakly efficient solutions(More)
To examine bacterial community composition in rhizosphere of plants colonizing on mine tailings and phylogenetic differences between subcommunities resistant to different metals, we constructed four clone libraries of 16S rDNA sequences. One was amplified directly from tailing microbial DNA (named as Ci library) and three from cultures on the plates(More)
L-glutamine stimulates glucagon-like peptide 1 (GLP-1) secretion in human subjects and cell lines. As recent advances have enabled the study of primary GLP-1-releasing L cells, this study aimed to characterize glutamine-sensing pathways in native murine L cells. L cells were identified using transgenic mice with cell-specific expression of fluorescent(More)
OBJECTIVE To investigate the effects of Trichophyton rubrum exposure on the expressions of toll-like receptor-2 (TLR-2), TLR-4 and dendritic cell associated C-type lectin-1 (Dectin-1) and cytokine secretions in human keratinocytes cell line HaCaT. METHODS The mRNA of TLR-2,4, and dectin-1 in the HaCaT co-cultured with the conidia of Trichophyton rubrum(More)
