Partly Olefinic Reference Structure Defined to Evaluate Bond Resonance Energy and the Ring Current It Would Sustain
The concept of bond resonance energy (BRE) is useful for estimating the degree of kinetic stability for a variety of polycyclic π-systems. In evaluating the BRE for a given π bond in a polycyclic π-system, the corresponding partly olefinic reference structure has been defined, in which cyclic conjugation via the π bond is forbidden. The ring-current pattern expected for such a hypothetical π-system were estimated graph-theoretically. Such a ring-current pattern proved very useful to visualizing and characterizing the mode of cyclic conjugation in a partly olefinic π-system
Select and Attend: Towards Controllable Content Selection in Text Generation
Many text generation tasks naturally contain two steps: content selection and
surface realization. Current neural encoder-decoder models conflate both steps
into a black-box architecture. As a result, the content to be described in the
text cannot be explicitly controlled. This paper tackles this problem by
decoupling content selection from the decoder. The decoupled content selection
is human interpretable, whose value can be manually manipulated to control the
content of generated text. The model can be trained end-to-end without human
annotations by maximizing a lower bound of the marginal likelihood. We further
propose an effective way to trade-off between performance and controllability
with a single adjustable hyperparameter. In both data-to-text and headline
generation tasks, our model achieves promising results, paving the way for
controllable content selection in text generation.Comment: EMNLP 201
Thermoelectric properties of partially filled skutterudites RxCo4Sb12 (R = Ce and Nd) synthesized under high pressures
We report the thermoelectric properties of the partially Ce or Nd filled skutterudite compounds CexCo4Sb12 and NdxCo4Sb12 prepared under high pressures and temperatures. The samples were characterized by X-ray diffraction. The actual filling ratio x of Ce or Nd was estimated by scanning electron microscopy (SEM) with energy-dispersive X-ray spectrometry (EDX). SEM-EDX results indicate that the maximum x values of Ce and Nd can be increased to 0.37 and 0.33, respectively. These values have been considered the highest for any CexCo4Sb12 and NdxCo4Sb12 reported thus far. The electrical resistivity, thermal conductivity, and Seebeck coefficient measurements of the compounds were performed from 5 to 760 K. Furthermore, the Hall coefficient and specific heat of the compounds were also measured below 300 K. The Seebeck and Hall coefficients of both Ce- and Nd-filled samples exhibited the n-type conductor behavior. The maximum dimensionless figure-of-merit (ZT) values of CexCo4Sb12 and NdxCo4Sb12 were determined to be 0.26 and 0.48 at 700K, respectively. (C) 2018 The Japan Society of Applied Physic
Methodology for Analyzing Coupling Mechanisms in RFI Problems based on PEEC
In This Article, a Method for Analyzing Coupling Mechanisms in Radio Frequency Interference (RFI) Problems is Proposed. the Partial Element Equivalent Circuit (PEEC) Method is First Used to Derive the Retarded Inductances and Capacitances between Different Mesh Cells. with the Introduction of a Novel Partitioning Algorithm, the Capacitive Coupling and Inductive Coupling between Arbitrary Layout Parts Can Be Quantified based on the Magnitude of the Displacement Current and Induced Voltage Drop. the Accuracy of the PEEC Models is Validated by Comparison with Different Commercial Tools. the Proposed Coupling Mechanism Analysis Flow Provides a Useful Prelayout Tool for RFI Risk Analysis
