Breaking Down Barriers: Examining the Accessibility of Global Water Futures Research
(University of Waterloo, 2023)The Global Water Futures program (GWF) was granted $77.8 million by the Canada First Research Excellence Fund to conduct research on the forecasting and management of water futures in Canada as part of an effort to combat ... -
Polynomial bounds for chromatic number VII. Disjoint holes.
(Wiley, 2023-05-14)A hole in a graph G is an induced cycle of length at least four, and a k-multihole in G is the union of k pairwise disjoint and nonneighbouring holes. It is well known that if G does not contain any holes then its chromatic ... -
Myokines and adipokines in sarcopenia: understanding cross-talk between skeletal muscle and adipose tissue and the role of exercise
(Elsevier, 2020-06)Detrimental age-associated changes in skeletal muscle and adipose tissue increase the risk of sarcopenia. Age-related changes in myokines, such as myostatin and irisin, as well as adipokines, such as leptin and adiponectin, ... -
Development of a bedside-applicable ultrasound protocol to estimate fat mass index derived from whole body dual-energy x-ray absorptiometry scans
(Elsevier, 2019-01)Objectives: Precise measures of adiposity are difficult to obtain in clinical settings due to a lack of access to accurate and reliable techniques. The aim of this study was to develop and internally validate a bedside-applicable ... -
Body size normalization of ultrasound measured anterior upper leg muscle thickness in younger and older males and females
(Nature Publishing Group, 2022-01)BACKGROUND: Ultrasound measurements of the anterior upper leg muscle thickness are often used to quantify muscle mass; however, the ideal normalization approach is unclear. Our primary objective was to examine how the ... -
Association of strength, power, and physical performance with muscle mass and composition in older males: a comparison of muscle thickness, echo intensity, and lean tissue mass
(Canadian Science Publishing, 2022-05)Dual-energy X-ray absorptiometry (DXA) appendicular lean tissue is used to screen older adults for sarcopenia. However, emerging data indicates that ageing-related muscle atrophy largely occurs within specific muscles, ... -
Influence of subcutaneous adipose tissue and skeletal muscle thickness on rectus femurs echo intensity in younger and older males and females
(Wiley, 2022-09)Objectives—Ultrasound measurements of muscle echo intensity are commonly used surrogates of muscle composition (eg, intramuscular adipose tissue). However, given that soundwaves are increasingly attenuated with tissue ... -
Rectus abdominis muscle thickness is a valid measure of cross-sectional area: implications for ultrasound
(Elsevier, 2022-03)Rationale and objectives: The rectus abdominis muscle exhibits early and significant muscle atrophy, which has largely been characterized using ultrasound measured muscle thickness. However, the validity of rectus abdominis ... -
Older males exhibit reduced anterior upper leg and anterior abdominal muscle thickness compared to younger males when matched for relative appendicular lean tissue
(Elsevier, 2021-10)Background Ageing-related muscle atrophy does not occur uniformly across the body; rather, atrophy occurs to a greater extent in specific muscle groups compared to others. However, site-specific comparisons of muscle mass ... -
Site-specific skeletal muscle echo intensity and thickness differences in subcutaneous adipose tissue matched older and younger adults
(Wiley, 2021-03)Background: Age-related deterioration of muscle mass does not occur uniformly across the body. However, there is limited knowledge on the uniformity of age-related muscle composition changes across the body. Objective: ... -
Ultrasound image resolution influences analysis of skeletal muscle composition
(Wiley, 2020-06-03)Introduction: Analysis of muscle composition using ultrasound requires standardization of several equipment settings (i.e. gain). However, the influence of image resolution, which is altered by imaging depth, on measures ... -
Assessment of skeletal muscle mass in critically ill patients: considerations for the utility of computed tomography imaging and ultrasonography
(Wolters Kluwer, 2016-03)Purpose of review: Low muscularity and skeletal muscle atrophy are commonly exhibited in critically ill patients and have major implications on patient outcomes. Typically, in the ICU, body composition is assessed through ... -
Indium Oxide Doped Polyaniline for Detection of Formaldehyde
(Wiley, 2022-06-22)Polyaniline (PANI) and a polyaniline derivative (poly (2,5-dimethyl aniline)) were evaluated for their sensitivity towards formaldehyde. Among the two polymer backbones evaluated, polyaniline seemed more sensitive towards ... -
Women’s Words and the Words of Women in the Oxford English Dictionary, 1700–2022, Supplementary Data & Notes
(The Life of Words, 2023-05-01)This Supplementary Data document collects notes on data and methodology, as well as supplementary aggregated data, underlying the analyses presented in David-Antoine Williams, ‘Women’s Words and the Words of Women in the ... -
Factors of Haptic Experience across Multiple Haptic Modalities
(Association for Computing Machinery, 2023-04-19)Haptic Experience (HX) is a proposed set of quality criteria useful to haptics, with prior evidence for a 5-factor model with vibrotactile feedback. We report on an ongoing process of scale development to measure HX, and ... -
Die Teilung ‚Armeniens‘ durch Caesar und die Entstehung ‚Kleinarmeniens‘
(Steiner Verlag, Stuttgart, Germany, 2021-08-01)Cicero states that Caesar withdrew Armenia from Deiotaros, Cassius Dio has him cede a part to Ariobarzanes and the Bellum Alexandrinum (66.5) implies that Armenia Minor was given (perhaps partly) to Ariobarzanes III’s ... -
Die geopolitische Bedeutung der Flüsse Tanais und Kalykadnos in den Territorialklauseln des Friedensvertrags von Apameia (Liv. 38,38,4.9)
(Steiner Verlag, Stuttgart, Germany, 2021-08-01)The Roman-Seleukid War (192–188 BC) resulted in the reorganization of Asia Minor, as sealed by the Treaty of Apameia. Its basic conditions are well known: Antiochus III withdrew from the areas north of the Taurus Mountains ... -
The Impact of Goal Progress Velocity on Affect While Pursuing Multiple Sequential Goals
(American Psychological Association, 2020)Past research has identified velocity (i.e., rate of goal progress) as a determinant of individuals’ affective experiences during goal pursuit. Specifically, rapid progress is a pleasant experience, whereas slow progress ... -
Seleucid Throne Wars: Resilience and Disintegration of the Greatest Successor Kingdom from Demetrius I to Antiochus VII
(Society of Biblical Literature, 2021-07-01)The present narrative of Seleucid dynastic history is written against a scholarly background that tended to emphasize the weakness of the kingdom beginning with the death of Seleucus I Nicator (316/12–281). But there had ... -
