The strong subadditivity of entropy plays a key role in several areas of physics and mathematics. It states that the entropy S[̺] = −Tr ( ̺ ln̺ ) of a density matrix ̺123 on the product of three Hilbert spaces satisfies S[̺123] − S[̺23] ≤ S[̺12] − S[̺2]. We strengthen this to S[̺123]−S[̺12] ≤ ∑ α n ( S[̺ 23 ]−S[̺α 2 ] ) , where the n are weights and the ̺ 23 are partitions of ̺23. Correspondingly, there is a...
پژوهش صورت پذیرفته که در این رساله ارائه گردیده است در رابطه با بکارگیری شیمی کوئوردیناسیون و شیمی ابر مولکولی در زمینه ی پلیمرهای کئوردیناسیونی می باشد. علاوه بر آن تغییرات جزئی در مواد واکنش دهنده و روند واکنش سبب ایجاد اثرات قابل توجهی بر روی محصولات گردیده است که این اثرات نیز مورد مطالعه قرارگرفته اند. در نهایت به اثر هالیدها برروی انباشتگی کریستالی پلیمرهای کوئوردیناسیونی جیوه و کمپلکس ها...
The aim of the present study was to investigate the effects of three blood purification methods on fibroblast growth factor-23 (FGF-23) clearance in patients with hyperphosphatemia undergoing maintenance hemodialysis (MHD). In addition, the correlation between serum FGF-23 and phosphorus (Pi) levels and the clinical implications were identified. Sixty-five MHD patients with hyperphosphatemia we...
Sonoluminescence is explained in terms of quantum radiation by moving interfaces between media of di erent polarizability. It can be considered as a dynamic Casimir e ect, in the sense that it is a consequence of the imbalance of the zero-point uctuations of the electromagnetic eld during the non-inertial motion of a boundary. The transition amplitude from the vacuum into a two-photon state is ...
Semileptonic heavy → heavy and heavy → light meson transitions are studied as a phenomenological application of a heavy-quark limit of Dyson-Schwinger equations. Employing two parameters: E, the difference between the mass of the heavy meson and the effective-mass of the heavy quark; and Λ, the width of the heavy-meson Bethe-Salpeter amplitude, we calculate f+(t) for all decays on their entire ...
