.G. W., colored, aged sixty-four, was admitted to the hospital Dee. 21, 1930, complaining of indeflnite abdominal pains and vaginal bleeding. The family and past history was irrelevant. The patient began to menstruate a t twelve years, and up to the present illness had always been normal as to cycle and duration. She was married at the age of forty, and her husband had died ten years later. The...

Atrial fibrillation (AF) is a cardiac condition characterized by an irregular heart rhythm, which increasingly prevalent in the modern era. All international guidelines strongly advise administration of anticoagulants to individuals with AF who are at high risk stroke. These recommend use direct oral (DOACs) over warfarin because significantly associated increased rates major bleeding, numerous...

although treated properly for epilepsy, a number of epileptic children have intractable seizures and about 5-10 per cent of them do not respond to anti -epileptic drugs. in the years 1986-1996 about 10,000 epileptic patients were treated in the children's medical center in tehran. a retrospective study of their medical records revealed that 41 of them had intractable seizures. i of these 4...

Mass spring systems (MSS) are frequently used to simulate deformable objects because of their conceptual simplicity and computational speed. Unfortunately, the model parameters (spring coefficients, masses) are not related to material constitutive laws in an obvious way. In our earlier work we proposed a method, which can be used to relate the parameters of the MSS to constitutive models, often...

We present a volumetric method that can e ciently create triangular meshes from 3-D geometric data. This data can be presented in the form of images, pro les or unordered points. The mesh model can be created at di erent resolutions and can also be closed to make a true volumetric model.

A 26-year-old lady presented to our emergency department on April 6, 2008, referred from a rural hospital as threatened abortion, with bleeding per vagina and pain abdomen, carrying 5 months’ pregnancy. She had been bleeding per vagina from the April 5 and gave history of occasional spotting. She also gave history of post-coital bleeding over a period of 8–9 months. She had two previous success...

Several “distances” between the spectra of two regular matrix pencils are discussed and compared. The relations obtained enable us to estimate upper bounds on one “distance” via known upper bounds on others. We also give some perturbation bounds and then show how to apply the relations obtained in this note.

A multilinear approach based on Grassmann representatives and matrix compounds is presented for the identification of reducing pairs of subspaces that are common to two or more matrices. Similar methods are employed to characterize the deflating pairs of subspaces for a regular matrix pencil A+ sB, namely, pairs of subspaces (L,M) such that AL ⊆ M and BL ⊆ M.
