PURPOSE To evaluate the clinical usefulness of binocular multifocal electroretinography (mfERG) by comparing results with conventional monocular mfERG in patients with monocular macular disease. METHODS mfERG testing was conducted on 32 patients with monocular macular disease and 30 normal subjects. An initial mfERG was simultaneously recorded from both eyes with two recording electrodes unde...

The current study investigated inter-digit co-ordination and object-digit interaction during sustained object holding tasks by using five, six-component force/torque sensors. The sum of the individual finger normal forces and the thumb normal force showed a parallel variation with a mean median correlation coefficient of 0.941. The normal force traces demonstrated the lowest coefficient of vari...

The Cambridge Fast Ring is a high speed slotted ring. The features that make it suitable for use at very large transmission rates are the synchronous transmission, the simplicity of the MAC protocol and the possibility of immediate retransmission of erronous packets. A new analytical model of the Cambridge Fast ring with normal slots is presented in this paper. The model shows to be accurate an...

It is shown how new integral-geometric formulae can be obtained from the existing of Crofton type. In particular, for classical in which answer depends on Riemannian volume, we obtain generalizations terms mixed volume defined paper. The method based calculations ring normal densities constructed previous work authors.

in this paper we prove that each element of any regular baer ring is a sum of two units if no factor ring of r is isomorphic to z_2 and we characterize regular baer rings with unit sum numbers $omega$ and $infty$. then as an application, we discuss the unit sum number of some classes of group rings.

let $f: arightarrow b$ be a ring homomorphism and let $j$ be an ideal of $b$. in this paper, we investigate the transfer of the property of coherence to the amalgamation $abowtie^{f}j$. we provide necessary and sufficient conditions for $abowtie^{f}j$ to be a coherent ring.

Janet’s algorithm to create normal forms for systems of linear pdes is outlined and used as a tool to construct resolutions for finitely generated modules over polynomial rings over fields as well as over rings of linear differential operators with coefficients in a differential field. The main result is that a Janet basis for a module allows to read off a Janet basis for the syzygy module. Two...

In the title compound, C7H21B3N6O3, the r.m.s. deviation of the borazine ring atoms is 0.019 Å. The dimethyl-amino groups are orientated at 41.80 (7) and 36.43 (7)° with respect to the borazine ring. The nitro-oxy group is almost normal to the borazine ring [dihedral angle = 85.33 (14)°]. The methyl C atom trans to the NO3 group is displaced by -0.512 (3) Å from the ring plane, whereas the two ...

Ring Y chromosome is a very rare chromosomal aberration. The published mixed gonadal dysgenesis (MGD) patients with a ring Y chromosome are short in stature, but are not growth hormone (GH) deficient. We present the molecular cytogenetic and molecular characterization of ring Y chromosome mosaicism in a 10-year-old boy with MGD whose short stature could be explained by the high percentage of ce...
