in this paper we present our studies using pauling electrostatic bond strength (esb) rules forstructural behaviour, cation vacancies, relation between x, y, and the valence of cations and coordinationin spinel compounds lixmn2o4, 0
Article history: Received 10 January 2008 Available online 10 December 2008 JEL classification: C72 D72 We study a game in which candidates first choose platforms and then invest in costly valences (e.g., engage in campaign spending). The marginal return to valence depends on platform polarization—the closer platforms are, the more valence affects the election outcome. Consequently, candidates ...
This paper reports on a experiment to identify the emotional loading (the “valence”) of news headlines. The experiment reported is based on a resource-thrifty approach for valence annotation based on a word-space model and a set of seed words. The model was trained on newsprint, and valence was computed using proximity to one of two manually defined points in a highdimensional word space — one ...
Yb 3d and valence-band photoemission spectra of the first-order valence-transition compound YbInCu4 have been measured with hard x ray at an excitation energy of 5.95 keV. Abrupt changes are clearly observed in both spectra around the transition temperature T(V)=42 K, in comparison with ultraviolet and soft x-ray photoemission (VUV-PES and SX-PES) spectra. From the Yb 3d spectra, the Yb valence...
introduction to extract and combine information from different modalities, fusion techniques are commonly applied to promote system performance. in this study, we aimed to examine the effectiveness of fusion techniques in emotion recognition. materials and methods electrocardiogram (ecg) and galvanic skin responses (gsr) of 11 healthy female students (mean age: 22.73±1.68 years) were collected ...
This essay provides a perspective on several issues in valence bond theory: the physical significance of semilocal bonding orbitals, the capability of valence bond concepts to explain systems with multireferences character, the use of valence bond theory to provide analytical representations of potential energy surfaces for chemical dynamics by the method of semiempirical valence bond potential...
The existence of the cubic perovskite phase SnTaO3 has been confirmed by using the bond valence model. The bond valence analysis of the crystal structure of SnTaO3 involved (i) evaluating the reliability of the bond valence parameters reported earlier for Sn(II)—O bonds; (ii) determining the hitherto unreported bond valence parameters for Ta(IV)—O bonds; (iii) calculating the bond valence sums ...
How do humans perform difficult forced-choice evaluations, e.g., of words that have been previously rated as being neutral? Here we tested the hypothesis that in this case, the valence of semantic associates is of significant influence. From corpus based co-occurrence statistics as a measure of association strength we computed individual neighborhoods for single neutral words comprised of the 1...
Emotional stimuli have evolutionary significance for the survival of organisms; therefore, they are attention-grabbing and are processed preferentially. The neural underpinnings of two principle emotional dimensions in affective space, valence (degree of pleasantness) and arousal (intensity of evoked emotion), have been shown to be dissociable in the olfactory, gustatory and memory systems. How...
The present study analyses the relationship between Anxiety and Impulsivity personality factors and emotions, by controlling for country and sex effects in a sample of Spanish and Swiss university students. Emotions were assessed through the International Affective Picture System (IAPS) of pictures (valence/ arousal) using the Self-Assessment Manikin (SAM) procedure. The mixed valence/arousal g...
