Aberrant cortical activity in 5xFAD mice in response to social and non-social olfactory stimuli (Postprint)
(IOS Press, 2024-01-16)Background: Neuroimaging studies investigating the behavioural and psychological symptoms of dementia (BPSD)—such as apathy, anxiety, and depression— have linked some of these symptoms with altered neural activity. However, ... -
Absolute probability estimates of lethal vessel strikes to North Atlantic right whales in Roseway Basin, Scotian Shelf
(2012-10)Vessel strikes are the primary source of known mortality for the endangered North Atlantic right whale (Eubalaena glacialis). Multi-institutional efforts to reduce mortality associated with vessel strikes include vessel-routing ... -
The Acadian fold belt in the Meguma Terrane, Nova Scotia; cross sections, fold mechanisms, and tectonic implications
(American Geophysical Union, Washington, DC, 2006-06)No abstract available. -
Accelerometer tags: detecting and identifying activities in fish and the effect of sampling frequency
(2013-04)Monitoring and measuring the behaviour and movement of aquatic animals in the wild is typically challenging, though micro-accelerometer (archival or telemetry) tags now provide the means to remotely identify and quantify ... -
The Acceptability of Deception in Pediatric Research
(Wolters Kluwer, 2015)Objective: Deception has been used to investigate the role of developmental and behavioral factors in child health; however, its acceptability for use in pediatric research has received little empirical attention. This ... -
Accessibility Door Usage and Associated Cost on Studley Campus
(2017-04)The purpose of this study is to quantify the cost of the usage of accessibility doors across Dalhousie University's Studley campus; the social cost takes into account the internal costs (cost of electricity and heating) ... -
Accounting for Intrinsic Nonlinearity in Non-Linear Regression Parameter Inference Regions
(1982-1982)No abstract available. -
Accounting for Nature: An Audit & Ranking of Indoor Green Spaces in Student-Use Buildings at Dalhousie University
(2019-04)Poor indoor air quality has been linked to an increase in health conditions such as asthma, lung cancers, cardiovascular disease, decreased lung function, and more. (Claudio, 2011; Dr. Daniel Rainham, personal communication, ... -
Accurate Spectral energy distributions and selection effects for high-redshift dusty galaxies: a new hot population to discover with the Spitzer Space Telescope?
(2004-08-10)The spectral energy distributions (SEDs) of dust-enshrouded galaxies with powerful restframe far-infrared emission have been constrained by a range of ground-based and space-borne surveys. The IRAS catalog provides a ... -
Acoustic backscatter inversion for suspended sediment concentration and size: A new approach using statistical inverse theory
(Elsevier, 2015)A new method is introduced for estimating suspended sediment concentration and grain size from acoustic backscatter observations, incorporating techniques from linearized statistical inverse theory and data assimilation. ... -
Acoustic Modelling to Inform Policies: Mitigating Vessel Noise Impacts on Arctic Cetaceans Within the Tallurutiup Imanga National Marine Conservation Area
(2018-11)Vessel traffic throughout the Canadian Arctic has tripled over the past 20 years and is not expected to decline. With the recent announcement of the Tallurutiup Imanga National Marine Conservation Area (TINMCA), the three ... -
Acoustic scattering from density and sound speed gradients: Modeling of oceanic pycnoclines
(Published for the Acoustical Society of America through the American Institute of Physics, 2012-01)A weak-scattering model that allows prediction of acoustic scattering from oceanic pycnoclines (and the accompanying sound speed gradients) based on hydrographic profiles is described. Model predictions, based on profiles ... -
Acoustic scattering from double-diffusive microstructure
(2007-09)Laboratory measurements of high-frequency broadband acoustic backscattering (200-600 kHz) from the diffusive regime of double-diffusive microstructure have been performed. This type of microstructure, which was characterized ... -
Acoustical features of song categories of the Adelaide's warbler (Dendroica adelaidae)
(1996)I identified acoustical features that distinguish the two song categories, A and B, of the Adelaide';s Warbler (Dendroica adelaidae). Like many other wood-warbler species, male Adelaide';s Warblers have functionally ... -

Activation and Deprotection of F-BODIPYs using Boron Trihalides
(2014)The activation of F-BODIPYs with boron trihalides, followed by treatment with a nuclephile, effects facile substitution at boron; using water as the nucleophile promotes deprotective removal of the–BF2 moiety and thereby ... -
Adaptive capacity of marine other effective area-based conservation measures (OECMs) in an era of global climate change: a case study analysis of Canada and the Scotian Shelf
(2023-12)Marine protected areas (MPAs) are often designed and managed with limited consideration of climate change and its impacts, potentially undermining their long-term efficacy. Other effective area-based conservation measures ... -
Adaptive optics near-IR imaging of NGC2992 - unveiling core structures related to radio figure-8 loops
(2000-05-11)We present near-IR adaptive optics, VLA radio and HST optical imaging of the nearby Seyfert galaxy NGC2992. Spiral structure and an extension to the West are traced down to the core region at the limiting resolution of our ... -
Adaptive Value and Costs of Physiological Plasticity to Soil Moisture Limitation in Recombinant Inbred Lines of Avena barbata
(2010-02)Costs are hypothesized to constrain the evolution of adaptive phenotypic plasticity, but they have been difficult to quantify because strong selection should eliminate costly genotypes from natural populations. However, ... -
