mobile luminal mass of aortic arch is an unusual finding in patients with peripheral embolization. to search the source of these emboli, aortic arch mass should be considered. to our knowledge, transesophageal echocardiography (tee) can be a useful modality to demonstrate the nature and exact location of the mass. this report is illustrative of a large mobile aortic arch mass, histologically th...

We provide a counterexample to Theorem 1 (A) in Dhillon [3]. 1 Dhillon’s Multi-Profile Version of Harsanyi’s Theorem on Utilitarianism In an important paper, Amrita Dhillon [3] provided a multi-profile version of Harsanyi’s [5] single-profile theorem on utilitarianism. Like Harsanyi did, she assumed that the social alternatives are lotteries. Individuals’ preferences satisfy the von Neumann-Mor...

phyllodes tumors account for less than 1% of breast tumors in women. giant phyllodes tumors are larger than 10 cm in diameter. a 40-year-old lady presented with a left breast lump that was present for two years. she underwent a simple mastectomy. the tumor was 30×26×21 cm in size, weighed 15 kg and had a density of 0.915 gr/cm3. we believe this patient had the third largest breast phyllodes tum...

We summarize the activity of the Very Large Hadron Collider Physics and Detector subgroup during Snowmass 96. ABSTRACT We summarize the activity of the Very Large Hadron Collider Physics and Detector subgroup during Snowmass 96. Members of the group:

Supersymmetry may be discovered at hadron colliders by searching for events similar to the top quark signal of two isolated leptons. In the case of gluino production, the most distinguishing feature is that in half the events the two leading leptons have the same sign. We demonstrate the remarkable sensitivity of this gluino signature at both the Fermilab Tevatron Collider and at the Supercondu...

We analyse the impact of matrix-element corrections to top decays in HERWIG on several observables related to the jet activity in tt̄ events at the Tevatron and at the LHC. In particular, we study the effects induced by the higher-order corrections to top decays on the top mass reconstruction using the recently proposed J/ψ + l final states.

We construct several new large sets of t-designs that are invariant under Frobenius groups, and discuss their consequences. These large sets give rise to further new large sets by means of known recursive constructions including an infinite family of large sets of 3− (v, 4, λ) designs. c © 1998 John Wiley & Sons, Inc.

late ripening citrus cultivars are very acceptable in the market. with respect to scarcity of late ripening citrus cultivars in iran, the project was conducted to produce a new late ripening cultivar for 21 years (1989-2009). the first phase (1989-1993) was started with controlled pollination between mineolla tangelo (citrus paradisi × c. reticulata) and changsha mandarin (c. changsha). after a...
