a group g is said to be a (pf)c-group or to have polycyclic-by-finite conjugacy classes, if g/c_{g}(x^{g}) is a polycyclic-by-finite group for all xin g. this is a generalization of the familiar property of being an fc-group. de falco et al. (respectively, de giovanni and trombetti) studied groups whose proper subgroups of infinite rank have finite (respectively, polycyclic) conjugacy classes. ...

Zusammenfassung: Die Replikation von Daten stellt in heterogenen, autonomen Informationssystemen hohe Anspruche an eine geeignete Replikationsstrategie. So müssen Schreibund Lesezugriffe auf die Replikate derart koordiniert werden, dass ein optimaler Kompromiss hinsichtlich der konkurrierenden Replikationsziele Verfügbarkeit, Performance und Konsistenz erreicht wird. Dieses Abwägen hinsichtlich...

Recent studies suggest that liver cirrhosis is reversible after administering oral nucleos(t)ide analogue therapy to patients with hepatitis B virus (HBV) infection. However, few studies have addressed whether esophageal varices can regress after such therapy. We report a case of complete regression of esophageal varices during entecavir therapy in patients with HBV-related liver cirrhosis, sug...

the concept of “infinite essence” that is both philosophically and theologically important, has passed many different evolutions in western history of thought. presocratics has evaluated it in two different ways. anaximender and melissus agree that the principle substance is infinite and divine, but neither absolutly transcendent nor anthropomorphic. the infinite is the fusis in its substantial...

Objectives: Several biologics therapy reportedly regress gastric amyloid deposition in AA amyloidosis patients, but it is uncertain whether they can also regress renal amyloid deposition. We carried out serial renal biopsy to clarify the regression of amyloid deposition in kidney by biologics. Methods: After the diagnosis of AA amyloidosis was determined by gastric biopsy to rheumatoid arthriti...

in this paper we consider the group algebra $r(c_2times‎ ‎d_infty)$‎. ‎it is shown that $r(c_2times d_infty)$ can be‎ ‎represented by a $4times 4$ block circulant matrix‎. ‎it is also‎ ‎shown that $mathcal{u}(mathbb{z}_2(c_2times d_infty))$ is‎ ‎infinitely generated‎.
