Swarm optimized organizing map (SWOM): A swarm intelligence based optimization of self-organizing map

WOS: 000266851000051This work studies the optimization of SOM algorithm in terms of reducing its training time by the use of a swarm intelligence method, i.e. particle swarm optimization (PSO). Our novel algorithm optimizes SOM with PSO and reduces computational time of the training phase of SOM significantly. The performance of the algorithms has been tested with genomic datasets. biomedical datasets and an artificial dataset to show the efficiency of swarm optimized SOM, i.e. SWOM. The experimental comparison between SOM and SWOM, has demonstrated significant reduction in training time of SWOM with preservation of clustering quality. (C) 2009 Elsevier Ltd. All rights reserved

Bazı yem ve gübre sanayi kimyasallarının hyalüronidaz üzerine in vitro etkileri

ABSTRACT This study investigates in vitro effects of some chemicals, used as a spreading factor on therapeutic and various medical fields and applied frequently in forage and fertilizer industry on bovine testicular hyaluronidase (BTH) which is substantially effective in glucotechnological applications and delivery of artificial insemination. BTH was purified through ammonium sulfate precipitation method and affinity gel (Sepharose-4B-L- tyrosine -m-anisidine). The inhibiton effects of Fe2SO4, C2H4N4, K2SiF6, CH2N2, CH4N2O and indole-butyric acid were determined on purified BTH. IC50 values of these chemicals were found as 7.097, 5.775, 6.854, 5.317, 4.617, 4.265 ×10-2 mM respectively and at the end of research, indole-butyric acid (IBA) was found as the strongest inhibitory effect compound by the value of IC50 with 4.265×10-2 mM

Synthesis and characterization of poly{2-[3-(1H-pyrrol-2-yl)phenyl]-1H- pyrrole} and its copolymer with EDOT

A pyrrole-functionalized monomer 2-[3-(1H-pyrrol-2-yl)phenyl]-1H-pyrrole (PyPhPy) was synthesized. The structure of monomer was investigated by Nuclear Magnetic Resonance ( 1H NMR) and Fourier Transform Infrared (FTIR) spectroscopy. The chemical polymerization of PyPhPy (CPyPhPy) was realized using FeCl3 as the oxidant. The electrochemical oxidative polymerization of polymer P(PyPhPy) and its copolymer with 3,4-ethylenedioxythiophene poly(2-[3-(1H- pyrrol-2-yl)phenyl]-1H-pyrrole-co-3,4- ethylenedioxythiophene) [P(PyPhPy-co-EDOT)] were achieved via potentiodynamic method by using NaClO 4/ LiClO 4 as the supporting electrolyte in CH 3CN. Characterizations of the resulting polymers were performed by cyclic voltammetry (CV), FTIR, scanning electron microscopy (SEM), UV-Visible spectrophotometry (UV- Vis) and thermogravimetry analyses (TGA). Electrical conductivity of CPyPhPy, P(PyPhPy), and P(PyPhPyco- EDOT) were measured by four-probe technique

Thrombus crossing through a patent foramen ovale

Paradoxical embolism across a patent foramen ovale (PFO) is a rare clinical entity and the thrombus is rarely caught passing through a PFO. A 65-year-old woman presented with dyspnea and pleuritic chest pain. Lower extremity venous Doppler ultrasound showed bilaterally extensive thrombosis at deep veins. Transthoracic echocardiographic examination showed two masses in both left and right atriums. In transesophageal echocardiography (TEE) interatrial septum was thin and aneurysmatic and a thrombus wedged through a patent foramen ovale and lodged in both atriums was demonstrated. We considered this mass as a thrombus crossing through a patent foramen ovale. He refused surgery and during anticoagulation therapy the patient had brachial artery embolism. Embolectomy material was reported as a thrombus. (C) 2007 Elsevier Ireland Ltd. All rights reserved

EFFECTS OF COLUMN FAILURES ON THE INTERNAL FORCES OF ORTHOGONAL REINFORCED CONCRETE BUILDING FRAMES

In this study, the effects of column failures which may take place due to the special causes such as blast, vehicle impact, insufficient or deficient design, on the internal forces of orthogonal reinforced concrete building frames have been investigated. Calculations have been performed with SAP2000 structural analysis program, under static conditions. For a typical frame system, firstly, various column failure scenarios have been considered for uninfilled case and internal forces have been calculated and compared with those in the intact case. Then, similar calculations have been implemented for the case of presence of infill walls. The results of analyses have shown that the effects of column failures had condensed on the neighbor columns and beams of orthogonal frames on which the columns had been failed. Moreover, it has been determined that, while the bending moment capacities of the connected beams to the failed columns had exceeded in the bare frames, in the masonry infilled frames, walls give substantial support to the structural elements of the building, and capacities of the beams had not exceeded

An Unusual Case of Madelung's Disease with Multiple Atypical Fractures

Madelung's disease is a rare acquired disorder of fat metabolism characterized by multiple symmetric lipomas with typical distribution mainly around the upper trunk, neck, and shoulders. The condition is strongly associated with chronic alcohol use and has various systemic manifestations like polyneuropathy, muscle weakness, and small bone fractures. Herein, we report a 56-year-old male patient with Madelung's disease and multiple fractures and discuss possible underlying factors leading to multiple fractures
