#### A micropower-compatible time-multiplexed SC speech spectrum analyzer design

(1993)

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

(1993)

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

(1993)

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

(1993)

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

(1993)

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

(1993)

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

(1993)

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)

(1993)

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

(1993)

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

(1993)

Let Σ0,…,Σ6 be the graphs from the Suzuki chain [12]. 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 ...
