We report a case of multiple myeloma with gastric involvement occurring in a patient who underwent an upper gastrointestinal series (UGIS), CT and MRI. UGIS depicted a luminal protruding mass, while contrast-enhanced CT demonstrated marked thickening of the gastric wall, with subtle contrast enhancement. At T1- and T2-weighted MR imaging, the mass showed iso- and intermediate signal intensity, ...

This paper presents a Taylor series approach for solving linear fractional de-centralized bi-level multi-objective decision-making (LFDBL-MODM) problems with asingle decision maker at the upper level and multiple decision makers at the lower level.In the proposed approach, the membership functions associated with each objective(s) ofthe level(s) of LFDBL-MODM are transformed by using a Taylor s...

Schur's theorem and its generalisation, Baer's theorem, are distinguished results in group theory, connecting the upper central quotients with lower series. The aim of this paper is to generalise these two different directions, using novel methods related non-abelian tensor product. In particular, we prove a version Schur–Baer for finitely generated groups. Then, apply newly obtained describe k...

In this paper a two-dimensional non-oriented guillotine bin packing problem is studied when items have different priorities. Our objective is to maximize the total profit which is total revenues minus costs of used bins and wasted area. A genetic algorithm is developed to solve this problem where a new coding scheme is introduced. To evaluate the performance of the proposed GA, first an upper b...

[1] Broadband seismic experiments over the last two decades have produced dense data coverage across Tibet. Yet, the mechanism of the India-Asia lithospheric convergence beneath it remains a puzzle, with even its basic features debated and with very different end-member models advocated today. We measured highly accurate Rayleighand Love-wave phase-velocity curves in broad period ranges (up to ...

frasnian - famennian boundary in the kal-e-sardar section (east of tabas, central iran) is investigated on the basis of conodonts. distribution of thirty-three species and subspecies in the stratigraphic column enables us to recognize a barren interval and five biozones; upper rhenana, upper part of upper rhenana - linguiformis, lower to middle triangularis, upper triangularis, lower crepida. b...

A set of computer programs and data tables of TTSE method to calculate the transport properties of water and steam has been developed. Its accuracy and computing speed were compared to those widely used in current industrial applications. The computing time was found to be half of the current method in the compressed-water and superheated-steam regions, and one-tenth in the supercritical region...
