Social dynamic opinion models have been widely studied to understand how interactions among individuals cause opinions to evolve. Most opinion models that utilize spin interaction models usually produce a consensus steady state in which only one opinion exists. Because in reality different opinions usually coexist, we focus on non-consensus opinion models in which above a certain threshold two ...

Reactions of [Pd(styrene)(PR3)2], generated from trans-[PdEt2(PR3)2] and styrene, with 2 equiv. of benzyl isocyanate in THF at room-temperature afforded unusual cyclic Pd-tetramers of five-membered rings consisting of organic isocyanate dimers and palladium, [Pd(PR3){-C(O)N(R)C(O)N(R)-}]4 (PR3 = PMe3, ; PR3 = PMe2Ph, ). Additionally, a cyclic trimer, (RNCO)3, (R = benzyl) was produced as a cata...

The flexible zwitterionic dicarboxylate ligand 1,4-bis(4-carboxylato-1-pyridinium)butane (bcpb) assumes different conformations to collaborate with pseudohalides in various coordination modes to produce coordination polymers in which distinct anionic motifs with mixed carboxylate and pseudohalide bridges are interlinked by the cationic butylenebis(pyridinium) tethers. The Cu(II) compound, [Cu2(...

Meiotic recombination initiated in prophase I of meiosis generates either crossovers (COs), which are reciprocal exchanges between chromosome segments, or gene conversion not associated to crossovers (NCOs). Both kinds of events occur in narrow regions (less than 10 kilobases) called hotspots, which are distributed non-homogenously along chromosomes. The aim of my PhD was the characterization o...

OBJECTIVE A new device, using whole body bioresistance measurements and a new equation for calculating stroke volume has been developed. Using this equation, an attempt was made to correlate whole body bioresistance cardiac output with thermodilution cardiac output in patients undergoing coronary artery bypass grafting. METHODS Thirty-one adults undergoing elective coronary artery bypass graf...

The numerically controlled oscillator (NCO) is one of the digital signal generators. It can generate clocked, synchronous, discrete waveform, and generally sinusoidal. Often NCOs care utilized in combinations to analog converter (DAC) at outputs for creating direct synthesizer (DDS). network on chips (NOCs) are various communication systems that fully or mixed signals such as synthesis arbitrar...

An environmentally friendly approach, which consists in coupling a dielectric barrier discharge (DBD) based atmospheric plasma treatment with coating of an aqueous phase polyurethane dispersion (PUD) containing blocked polyisocyanates, is proposed to improve the adhesion thermoplastic (TPU) film onto poly-(ethylene terephthalate) (PET) textile fabric. In this study, screening digital design exp...

This article discusses the limitations of Network Enabled Capability from the point of view of the dynamical properties of conflicts and the physical constraints of networks, rather than technological limitations. The discussion focuses principally on the observed power-law nature of conflict (that is to say, treating warfare as a hierarchy of conflicts within conflicts). It is suggested that t...

The basic properties of many pyrrolizidine alkaloids are well known l.5, A lthough they have been isolated from representatives of about 13 plant fami lies, they occur most abundantly in the large genera sen~cio (Asteraceae), Crola/aria (Papilionaceae) and in many members of Boraginaceae including Heliotropium and CynoglossUlI1. More recently they have been detected in LepidopheraJ,4 Over 75 sp...
