In a Symbiotic Cognitive Relaying (SCR) scenario, Secondary User (SU) nodes can act as multihop relays to assist communication between Primary User (PU) nodes in the case of a weak direct link. In return, the SU nodes are incentivised with the right to carry out SU-SU communication using licensed PU band for a fixed amount of time, referred to as the ‘Time Incentive’. Existing work on SCR is co...
We study the vacuum structure and dynamical symmetry breaking in the gaugeHiggs unification of the 5D theory compactified on an orbifold, S/Z2. This theory identifies Wilson line degrees of freedoms as “Higgs doublets”. We consider SU(3)c × SU(3)W and SU(6) models with the compactification scale of order a few TeV. The gauge symmetries are reduced to SU(3)c × SU(2)L × U(1)Y and SU(3)c × SU(2)L ...
The suppressor of forked (Su(f)) protein of Drosophila melanogaster is highly homologous to two proteins involved in mRNA 3'-end formation, the yeast RNA14 protein and the 77K subunit of human cleavage stimulation factor (CstF). This suggests a role for su(f) in mRNA 3'-end-processing, probably as part of Drosophila CstF. We have investigated the expression pattern of su(f) during Drosophila de...
در این پایان نامه ابتدا مدل استاندارد ذرات بنیادی را معرفی می کنیم. مدل استاندارد، ذرات بنیادی و برهمکنش های میان ذرات بنیادی را توسط لاگرانژی با تقارن غیر آبلی ?su(3)?_c×?su(2)?_l×?u(1)?_y توصیف می کند. سپس مکانیزم هیگز را توضیح می دهیم که مسئول جرم دار کردن ذرات و بوزون های پیمانه ای است. در ادامه برهمکنش های بوزون های الکتروضعیف مدل استاندارد را مورد مطالعه قرار می دهیم. قضیه هم ارزی بوزون گ...
We carry a systematic study of possible models based on the local gauge group SU(3)c ⊗ SU(3)L ⊗ U(1)X . Old and new models emerge from the analysis. The Standard Model (SM) based on the local gauge group SU(3)c ⊗ SU(2)L ⊗ U(1)Y [1] can be extended in different ways: first, by adding new fermion fields (adding a right-handed neutrino field constitute its simplest extension, and has deep conseque...
Cell fate choices during metazoan development are driven by the highly conserved Notch signalling pathway. Notch receptor activation results in release of the Notch intracellular domain (NICD) that acts as transcriptional co-activator of the DNA-binding protein CSL. In the absence of signal, a repressor complex consisting of CSL bound to co-repressors silences Notch target genes. The Drosophila...
In the context of a viable , supersymmetric, preon model, it has been shown by Babu and Pati that the unity of forces can well occur at the level of preons near the Planck scale. This preonic approach to unification is explored further in this note with the inclusion of threshold effects which arise due to spreading of masses near the scale of supersymmetry (MS = 1 TeV) and the metacolor scale ...
The Su(f) protein of Drosophila melanogaster shares extensive homologies with proteins from yeast (RNA14) and man (77 kD subunit of cleavage stimulation factor) that are required for 3' end processing of mRNA. These homologies suggest that su(f) is involved in mRNA 3' end formation and that some aspects of this process are conserved throughout eukaryotes. We have investigated the genetic and mo...
recobrase su firmeza. Como el tratamiento no tenía fecha de finalización Toda se vio obligada a regresar a Navarra, puesto que era la reina regente tras la muerte de su marido, dejando a su nieto en manos de los médicos árabes. El resultado de la dieta y el ejercicio físico no se hizo esperar, después de someterse durante 40 largos días a esta estricta y nociva dieta consiguió rebajar su peso a...
We study the modular invariance of N = 2 superconformal SU (1, 1) models. By decomposing the characters of Kazama-Suzuki model SU (3)/(SU (2)×U (1)) into an infinite sum of the characters of (SU (1, 1)/U (1)) × U (1) we construct modular invariant partition
