AbstructOblique projection operators are used to project measurements onto a low-rank subspace along a direction that is oblique to the subspace. They may be used to enhance signals while nulling interferences. In this paper, we give several basic results for oblique projections, including formulas for constructing oblique projections with desired range and null space. We analyze the algebra an...

We discuss the oscillation features of β Cephei, which is a magnetic star in which the magnetic axis seems to be oblique to the rotation axis. We interpret the observed equi-distant fine structure of the frequency spectrum as a manifestation of a magnetic perturbation of an eigenmode, which would be a radial mode in the absence of the magnetic field. Besides these frequency components, we inter...

purpose: to determine the effect of recession and myectomy on inferior oblique overaction (iooa). method: this study was performed on 50 patients (82 eyes) scheduled for iooa surgery who were randomly divided into two groups: recession (r) versus myectomy (m). a complete eye examination was performed before the operation. io was cut off at its inferior temporal region when using m procedure. in...

here, a new method called aboodh transform homotopy perturbation method(athpm) is used to solve nonlinear partial dierential equations, we presenta reliable combination of homotopy perturbation method and aboodh transformto investigate some nonlinear partial dierential equations. the nonlinearterms can be handled by the use of homotopy perturbation method. the resultsshow the eciency of this...

Traditional superior oblique weakening procedures may be unpredictable and lead to superior oblique underaction. The use of 240 retinal band as a spacer to lengthen the superior oblique tendon has been proposed as a more controlled approach than superior oblique tenotomy and related procedures. The use of this technique is reported in a patient with diplopia following an orbital floor blow out ...

PURPOSE To evaluate the efficacy of transposition of the belly of the inferior oblique muscle in treating inferior oblique overaction with small angle hypertropia. METHODS The medical records of 10 patients who underwent inferior oblique belly transposition from March 2014 to July 2016 were reviewed. Transposition of the inferior oblique muscle belly consisted of suturing the entire body of t...

PURPOSE To report masked superior oblique muscle tightness as a possible mechanism causing A-pattern exotropia with intorsion after inferior rectus muscle recession in the context of thyroid eye disease. METHODS Three patients with thyroid eye disease and involvement of the superior oblique muscle are presented, along with a fourth comparison case without superior oblique muscle involvement. ...

background: considering that complications and outcome of each method of pediatric inguinal hernia repair are one of the determinants for pediatric surgeons for selection of the appropriate surgical technique, we compared the early and late complications of two inguinal repair techniques, with and without opening the external oblique muscle fascia. materials and methods: in this double-blind cl...

The haptic perception of vertical, horizontal, +45 degrees oblique, and +135 degrees oblique orientations was studied in completely blind adults. The purpose was to determine whether the variations of the gravitational cues provided by the arm-hand system during scanning would affect the manifestation of the oblique effect (lower performance in oblique orientations than in vertical-horizontal o...

The development of a preferred crystallographic orientation in the plane of growth, an in-plane texture, is addressed in a model that incorporates anisotropic growth rates of a material and self-shadowing. Most crystalline materials exhibit fast growth along certain crystallographic directions and slow growth along others. This crystallographic growth anisotropy, which may be due to differences...
