Nonlocal Symmetries For Time-Dependent Order Differential Equations, Andrei Ludu

Publications

A new type of ordinary differential equation is introduced and discussed: time-dependent order ordinary differential equations. These equations are solved via fractional calculus by transforming them into Volterra integral equations of second kind with singular integrable kernel. The solutions of the time-dependent order differential equation represent deformations of the solutions of the classical (integer order) differential equations, mapping them into one-another as limiting cases. This equation can also move, remove or generate singularities without involving variable coefficients. An interesting symmetry of the solution in relation to the Riemann zeta function and Harmonic numbers is observed.

Measuring Job-Fit And Career Paths Of Distance Learning Lirbrarians, Jennifer J. Rundels, Anne M. Casey

Measuring Person-Job Fit and Career Paths of Distance Learning Librarians

While person-job fit has been used to determine satisfaction in many professions, no research has been done among distance learning (DL) librarians. This study explores that concept by investigating person-job fit among librarians with primary DL responsibility compared to librarians with partial DL responsibility and whether a common career path exists among the two groups. Responses appear to suggest that DL librarians perceive a strong compatibility between their needs and desires and their jobs while both groups indicate that career advancement has been the primary factor concerning career path decisions.

All Peer-Reviewed Publications

Foraging insect parasitoids use specific chemical cues to discriminate between host and non-host species. Several compounds have been identified in "host location and acceptance." However, nothing is known about the molecular variations in these compounds that could account for host-range differences between parasitoid species. In a previous study, it was shown that during the host-finding process, contact between the braconid Cotesia flavipes and its host is crucial, and that α-amylase of oral secretions from the host plays a key role for host acceptance and oviposition by the parasitoid. The present study sought to establish whether the variations in this enzyme …

Modeling Of Cantú Syndrome In Zebrafish, Soma Sekhara Singareddy

McKelvey School of Engineering Graduate Student Theses & Dissertations

Although rare, Cantú syndrome (CS) is a debilitating syndrome without any specific therapy, caused by gain-of-function (GOF) mutations in KCNJ8 and ABCC9 genes that encode ATP-sensitive potassium (KATP) channels. To better understand the link between molecular dysfunction and the complex pathophysiology, animal models that can rigorously mirror human CS are essential. Using ABCC9-mutated zebrafish, which can provide significant advantages over mice as an appropriate vertebrate model, GOF has been demonstrated at a cellular level in the ventricular cardiomyocytes. This also marks the first-known characterization of KATP currents in teleost hearts. In addition, sulfonylurea sensitivities of the channels have been …

Sources And Clinical Applications Of Mesenchymal Stem Cells: State-Of-The-Art Review, Roberto Berebichez-Fridman, Pablo R. Montero-Olvera

Sultan Qaboos University Medical Journal

First discovered by Friedenstein in 1976, mesenchymal stem cells (MSCs) are adult stem cells found throughout the body that share a fixed set of characteristics. Discovered initially in the bone marrow, this cell source is considered the gold standard for clinical research, although various other sources—including adipose tissue, dental pulp, mobilised peripheral blood and birth-derived tissues—have since been identified. Although similar, MSCs derived from different sources possess distinct characteristics, advantages and disadvantages, including their differentiation potential and proliferation capacity, which influence their applicability. Hence, they may be used for specific clinical applications in the fields of regenerative medicine and tissue …
