The purpose of the current study was twofold: (1) to determine the isometric force and electromyographic (EMG) relationship of the sternocleidomastoid, splenii and trapezii muscles bilaterally in graded and maximal exertions in the sagittal, coronal and oblique planes. and (2) to develop regression equations to predict force based on the EMG scores. A newly(More)
To the memory of A. Ramanathan Let G be a semisimple, simply connected algebraic group over an algebraically closed field of characteristic p > 0. Let U be the unipotent radical of a Borel subgroup B ⊂ G and u the Lie algebra of U. Springer [16] has shown for good primes, that there is a B-equivariant isomorphism U → u, where B acts through conjugation on U(More)
Persistent mullerian duct syndrome with transverse testicular ectopia is a very rare pathological association, often fortuitously discovered in boys during repair for inguinal hernia or cryptorchidism. The authors present the case of an 15 year old adolescent with cryptorchidism, in whom ultrasonography of the right iliac fossa showed 2 testicles and a(More)
In this paper we consider the eigenvalue problem, intersection theory of homogenous spaces (in particular, the Horn problem) and the saturation problem for the symplectic and odd orthogonal groups. The classical embeddings of these groups in the special linear groups will play an important role. We deduce properties for these classical groups from the known(More)
The generalized triangle inequalities for rank 3 symmetric spaces of noncompact type. Abstract We compute the generalized triangle inequalities explicitly for all rank 3 symmetric spaces of noncompact type. For SL(4, C) there are 50 inequalities none of them redundant by [KTW]. For both Sp(6, C) and Spin(7, C) there are 135 inequalities of which 24 are(More)
STUDY DESIGN An axial rotation tester was designed and fabricated for the study. This allowed stabilization of seated subjects (hip down) and coupling of shoulders, permitting axial rotation and coupled lateral flexion. Using this device, a "flexion-extension free" axial rotation was executed for studying its characteristics. OBJECTIVES To determine the(More)
Electromyographic (EMG) patterns of the trunk muscles were investigated during balance perturbations in a sitting position. Five healthy subjects (two females and three males, mean age 24.4 yr) were seated on a platform allowing rotational perturbations in the frontal and sagittal planes. Each of the forward, backward, right and left perturbations were(More)
