Polar Decompositions And Spectral Properties Of Linear Operator Pencils, Slaviša Djordjević, Jaewoong Kim, Jasang Yoon

School of Mathematical & Statistical Sciences Faculty Publications

In this paper, we introduce the spherical polar decomposition of the linear pencil of an ordered pair T=(T1,T2) . Using this decomposition, we define the generalized spherical Aluthge transforms for the linear pencil of an ordered pair T=(T1,T2) and give spectral properties between the linear pencil and the generalized spherical Aluthge transform of it. In detail, we study whether the spectral properties of the linear pencil of an ordered pair T=(T1,T2) are invariant under the generalized spherical Aluthge transform.

Generalizations Of Some Q-Product Identities Of Ramanujan And Others, Timothy J. Huber, James Mclaughlin, Dongxi Ye

School of Mathematical & Statistical Sciences Faculty Publications

By considering certain limiting cases of a WP-Bailey chain discovered by Andrews, and also limiting cases of certain classical summation formulae for basic hypergeometric series, we derive new expressions for certain Lambert series in terms of basic hypergeometric series. In some cases, the resulting series involve an arbitrary Bailey pair. This allows for the derivation of new basic hypergeometric expansions for some q-products and series that Ramanujan expressed in terms of Lambert series. Some of Ramanujan’s identities are extended to more general relations containing one or more free parameters.

Evaluating Sediment Storage Time For Improved Management Of River Basin Pollution, Enrique Munoz Arcos

School of Geography, Earth and Environmental Sciences Theses

Excess fine sediment supply and associated contaminants can have detrimental effects on water quality and river ecology, with sediment deposition on, and subsequent infiltration into, streambed substrate impacting riverine habitats. Significant research has assessed the magnitude, controls, and impacts of fine sediment in river channels. Assessment of the associated time scales, however, across these three domains has received less attention due in part to the complexity of river basin sediment dynamics. Fallout radionuclides (FRNs) applied as particle tracers in aquatic ecosystems can address this challenge. Herein, this research aimed to evaluate sediment storage time through application and development of FRN …

2020-Current year OA Pubs

BACKGROUND: Previous studies have shown that colorectal cancer incidence is increasing among younger adults (aged < 50 years) in multiple high-income western countries in contrast with stabilising or decreasing trends in incidence in older adults (aged ≥50 years). This study aimed to investigate contemporary colorectal cancer incidence trends in younger adults versus older adults.

METHODS: Colorectal cancer incidence data, including year of diagnosis, sex, and 5-year age group for 50 countries and territories, were extracted from the WHO-International Agency for Research on Cancer Cancer Incidence in Five Continents Plus database. The Human Development Index 2022 was retrieved from the United Nations Development Programme and grouped into very high (>0·80), high (0·70-0·79), medium (0·55-0·69), and low (< 0·55) categories. Age-standardised incidence rates (ASR) per 100 000 person-years of early-onset (diagnosed between ages 25 to 49 years) and late-onset (diagnosed between ages 50 to 74 years) colorectal cancer (ICD 10th revision, C18-20), diagnosed between 1943-2003 and 2015-17, were calculated using the direct method and Segi-Doll world standard population). The primary study objective was to examine contemporary colorectal cancer incidence trends in younger adults versus older adults using data until 2017 from 50 countries and territories. Temporal trends were visualised and quantified with joinpoint regression, stratified by age at diagnosis (25-49 years or 50-74 years). Average annual percentage changes (AAPC) were estimated.

FINDINGS: In the most recent 5 years (2013-17 for all countries analysed, except for Japan [2011-15], Spain [2012-16], and Costa Rica [2012-16]), …

Diagnosis And Management Of Gastroesophageal Reflux Disease: Current Insights, Abhinav Vayal-Veettil, C Prakash Gyawali

2020-Current year OA Pubs

Gastroesophageal reflux disease (GERD) results from retrograde movement of gastric content into the esophagus and beyond, resulting in symptoms, mucosal injury and long-term complications. Typical symptoms of heartburn and regurgitation are highly suggestive of GERD, but atypical presentations require careful evaluation to rule out alternative diagnoses. Diagnostic modalities, including endoscopy, ambulatory reflux monitoring, and high-resolution manometry, play a pivotal role in confirming GERD and guiding personalized treatment. Management strategies consist of lifestyle modifications, pharmacologic therapy with anti-secretory agents, and adjunctive treatments such as alginates and baclofen. For refractory cases, surgical and endoscopic interventions offer durable symptom relief. Complications of GERD …
