Thalassemias are hereditary anemia syndromes occurring due to erroneous producing of globin chain of hemoglobin. Thalassemia syndromes are named according to the type of the affected globin chain. The most common types of thalassemia are alpha thalassemia and beta thalassemia. In α-thalassemia, α-globin chain production is either by decreased or completely disappeared. The gene encoding the α-g...
In this paper, we consider an energy-efficient scheduling problem where n jobs J1, J2, . . . , Jn need to be executed such that the total energy usage of these jobs is minimized while ensuring that each job is finished within it’s deadline. We work in an online setting where a job is known only at it’s arrival time, along with it’s processing volume and deadline. In such a setting, the currentl...
The Automated Protein Structure Analysis (APSA) method is used for the classification of supersecondary structures. Basis for the classification is the encoding of threedimensional (3D) residue conformations into a 16-letter code (3D-1D projection). It is shown that the letter code of the protein makes it possible to reconstruct its overall shape without ambiguity (1D-3D translation). According...
This paper presents a new variant of broadband Doherty power amplifier that employs a novel output combiner. A new parameter αα is introduced to permit a generalized analysis of the recently reported Parallel Doherty power amplifier (PDPA), and hence offer design flexibility. The circuit prototype of the new DPA fabricated using GaN devices exhibits maximum drain efficiency of 85% at 43-dBm pea...
The results of evaluation of mixed QED×QCD corrections to R(s) in e+e− annihilation and Rτ in hadronic decay of the τ lepton to O(α αs ), m+n ≤ 3, are presented. The net effect on αs(MZ) from the Z decay is only about 0.1% and in the τ decay case the net effect is negligible, as expected. PACS numbers: 12.38.Bx, 13.38.Dg Typeset using REVTEX ∗[email protected] 1 Inclusive processes of the ...
We calculate the 10 × 10 two–loop anomalous dimension matrix to order O(ααs) in the dimensional regularization scheme with anticommuting γ5 (NDR) which is necessary for the extension of the ∆S = 1 weak Hamiltonian involving electroweak penguins beyond the leading logarithmic approximation. We demonstrate, how a direct calculation of penguin diagrams involving γ5 in closed fermion loops can be a...
