Axial equiform Bricard motions are equiform motions where each point of the moving system sticks to a sphere and additionally a line (the axis) is fixed throughout the motion. In this paper we show that there are only two types of such motions. The first one is determined by requiring that the axis is translated along itself and another line, which is skew to the axis, always contains a point o...

We present axial plane optical microscopy (APOM) that can, in contrast to conventional microscopy, directly image a sample's cross-section parallel to the optical axis of an objective lens without scanning. APOM combined with conventional microscopy simultaneously provides two orthogonal images of a 3D sample. More importantly, APOM uses only a single lens near the sample to achieve selective-p...

INTRODUCTION To evaluate whether eyes with longer axial lengths are associated more often with clinically significant cataracts than eyes with shorter axial lengths. MATERIAL AND METHODS Charts of consecutive patients who underwent cataract surgery by 4 resident surgeons at Los Angeles County Hospital from July 2001 through May 2002 were retrospectively reviewed. Those patients whose axial le...

A conventional 3rd generation Computed Tomography (CT) system with a single circular source trajectory is limited in terms of longitudinal scan coverage since extending the scan coverage beyond 40 mm results in significant cone-beam artifacts. A multiaxial CT acquisition is achieved by combining multiple sequential 3rd generation axial scans or by performing a single axial multisource CT scan w...

434 July/August 2005, Vol. 76/No. 6 RADIOLOGIC TECHNOLOGY Acromial spurring, bursitis, impingement, rotator cuff strains, tendonitis and traumatic injuries to the shoulder are familiar reasons for shoulder pain. To assist in the diagnosis, plain-film radiography is indispensable for studying shoulder abnormalities. Similarly, radiographs help to demonstrate the relationship of the glenoid fossa...

A baby girl referred from the newborn unit at day 1 of life with a pedunculated soft tissue 3x3.5x 3 cm mass located pre-axially on the palm at the base of her pollex finger. (Fig. 1) The rest of the local and systemic examination was normal. Ultrasonography of the abdomen did not reveal any other congenital anomaly. The lesion was excised. Histopathological examination reported the lesion to b...

We consider theories with gauged chiral fermions in which there are abelian anomalies, and no nonabelian anomalies (but there may be nonabelian gauge fields present). We construct an associated theory that is gauge-invariant, renormalizable, and with the same particle content, by adding a finite number of terms to the action. Alternatively one can view the new theory as arising from the origina...

The baryon axial currents are calculated at one–loop order in heavy baryon chiral perturbation theory by employing both a cutoff and dimensional regularization. Data from the semileptonic baryon decays is used to perform a least–squares fit to the two axial couplings D and F of the effective Lagrangian. Predictions for the momentum dependent axial form factors are made and the two different reg...

following recent works of several authors like huilgol, bhattacharya etd. and javadpour et al., this paper is to contribute further to the literature of axial flow in a rotational coaxial rheometer. we consider axial flow of herschel bulkley mode1 between two concentric cylinders with the inner one rotating, while the outer cylinder is held stationary. an attempt has been made to direct the ana...
