Background and Objective: Due to the overall wide range of oral manifestations and the lack of comprehensive categorized information in Iran, this study was performed to investigate the prevalence of different oral manifestations and report their possible associated factors in patients with SLE. Materials and Methods: This cross-sectional study was performed on 96 SLE patients referred to two ...

We examine the formation of giant elliptical galaxies using their globular cluster (GC) systems as probes of their evolutionary history. The bimodal distributions of GC metallicities in such galaxies are often cited as evidence for the formation of giant elliptical galaxies through mergers involving gas-rich spirals, with the metal-rich GCs forming during the merger process. We explore an alter...

We study the stability of the giant gravitons in the string theory background with NSNS B field. We consider the perturbation of giant gravitons formed by a probe D(8− p) brane in the background generated by D(p− 2)D(p) branes for 2 ≤ p ≤ 5. We use the quadratic approximation to the brane action to find the equations of motion. The vibration modes for ρ , φ and r are coupled, while those of xk’...

Paying off the mortgage, once a widespread rite of passage for homeowners approaching retirement, has become less common in recent years. Concerns are mounting that the increased prevalence of housing debt among older homeowners could compromise financial security in retirement by expanding housing affordability problems, crimping essential nonhousing spending, increasing vulnerability to home ...

We refine our algebraic axiomatization in [8, 9] of epistemic actions and epistemic update (notions defined in [5, 6] using a relational, Kripke-style semantics), to incorporate a mechanism for dynamic belief revision in a multi-agent setting. Our approach has a number of novel features, when compared with traditional belief revision systems such as AGM [2]. Firstly: while traditional belief re...
