A micropower-compatible time-multiplexed SC speech spectrum analyzer design
A micropower-compatible time-multiplexed sc speech spectrum analyzer embodying several new design methodologies is described. In the bandpass filter (BPF) section, the dc offset differences between channels are reduced by ...
Overwrite in thin film disk recording systems
Overwrite in thin film rigid disk recording has been studied experimentally using disks with a wide range of magnetic moment and coercivity. Standard f2/f1 overwrite was investigated in detail at various recording currents ...
Novel zinc finger motif in the basal transcriptional machinery : three-dimensional NMR studies of the nucleic acid binding domain of transcriptional elongation factor TFIIS
Transcriptional elongation provides a key control point in the regulation of eukaryotic gene expression. Here we describe homonuclear and lSN-heteronuclear 3D NMR studies of the nucleic acid binding domain ...
Structure of a new nucleic-acid-binding motif in eukaryotic transcriptional elongation factor TFIIS
Transcriptional elongation involves dynamic interactions among RNA polymerase and single-stranded and double stranded nucleic acids in the ternary complex1–4. In prokaryotes its regulation pro-vides an important mechanism ...
Shimura subgroups of Jacobians of Shimura curves
Given an indefinite quaternion algebra of reduced discriminant D and an integer N relatively prime to D, one can construct Shimura curves Sh0(N, D) and Sh1(N, D), which are analogues of X0(N) and X1(N). The natural morphism ...
Dipolar unit size in coupled-dipole calculations of the scattering matrix elements
The coupled-dipole method is widely used to calculate the light-scattering matrix S from arbitrary particles. An important parameter in the model is the size of the dipolar subunits. Usually a size of ~1/10 to ~1/20 of the ...
On some locally 3-transposition graphs
Let ∑_n^ε be the graph defined on the (+)- points of an n-dimensional GF(3)-space carrying a nondegenerate symmetric bilinear form with discriminant ε, points are adjacent if they are perpendicular. We prove that if ε = ...
A local characterization of the graphs of alternating forms and the graphs of quadratic forms over GF(2)
Let Δ be the line graph of PG(n –1,2), Alt(n,2) be the graph of the n-dimensional alternating forms over GF(2), n ≥ 4. Let Γ be a connected locally Δ graph such that 1. the number of common neighbours of any pair of vertices ...
New examples of finite C ˜ 2-geometries
The aim of this note is to present a series of examples of finite geometries with diagram, where q=2k and GQ-residues are of type T*2(T ∗ 2 (O) ).
Geometric characterization of graphs from the suzuki chain
Let Σ0,…,Σ6 be the graphs from the Suzuki chain . We classify connected locally Σi graphs Θi + 1 for i = 3, 4, 5. If i = 3, 4 then Θi + 1, is isomorphic to Σi + 1, whereas Θ6 is isomorphic either to Σ6 or to its 3-fold ...
