"The part of me that you bring out": Ideal similarity and the Michelangelo phenomenon.

This work examines the Michelangelo phenomenon, an interpersonal model of the means by which people move closer to (vs. further from) their ideal selves. The authors propose that partner similarity--similarity to the ideal self, in particular--plays an important role in this process. Across 4 studies employing diverse designs and measurement techniques, they observed consistent evidence that when partners possess key elements of one another's ideal selves, each person affirms the other by eliciting important aspects of the other's ideals, each person moves closer to his or her ideal self, and couple well-being is enhanced. Partner similarity to the actual self also accounts for unique variance in key elements of this model. The associations of ideal similarity and actual similarity with couple well-being are fully attributable to the Michelangelo process, to partner affirmation and target movement toward the ideal self. The authors also performed auxiliary analyses to rule out several alternative interpretations of these findings. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

A Simple Least-Squares Design of M-D IIR Filters with Fixed Separable Denominator Based on Multivariate Division Algorithm

Inthis paper, we propose a simple algorithmic solution to the bestapproximation problem of finding the nearest multivariate rationalfunction, with a fixed separable denominator polynomial, froma given multivariate polynomial, where the numerator polynomialis desired to minimize the integral of the squared error overthe distinguished boundary of the unit polydisc. The proposedalgorithm does not require any numerical integration or numericalroot finding technique because this is realized based on thestandard multivariate division algorithm.A simple observation of the proposed algorithmleads to an ideal membership problem characterizing the solutionto the problem. A relation of this characterization and a multivariategeneralization of the Walsh's Theorem is also discussed withanother ideal membership problem derived by applying a corollaryof the Hilbert Nullstellensatz to the Walsh's Theorem. Althoughthe discussion to derive the latter ideal membership problemseems to be roundabout, such a characterization would be usefulfor further generalization, for example to some weighted least-squaresapproximation.Numerical examples demonstratethe practical applicability of the proposed method to designproblems of multidimensional IIR filters.     

试从仲长统的“乐志”诗文看汉末士人的理想栖居

仲长统在《乐志文》、《乐志诗》中为汉末士人描绘了一幅物质富裕、精神自由的理想生活画卷,并透露出此期士人在思想、经济、政治立场及文学上的新动向。这种理想栖居与先秦儒家之＂乱世则隐＂理念一脉相承。同时,因士阶层自身经济地位的局限性,这种理想在现实生活中无法实现。

Normalization of rings

We present a new algorithm to compute the integral closure of a reduced Noetherian ring in its total ring of fractions. A modification, applicable in positive characteristic, where actually all computations are over the original ring, is also described. The new algorithm of this paper has been implemented in Singular, for localizations of affine rings with respect to arbitrary monomial orderings. Benchmark tests show that it is in general much faster than any other implementation of normalization algorithms known to us.     

Vibrational Frequencies and Ideal Gas Heat Capacities of Fluorochloro-Derivatives of Methane as Calculated from Quantum Mechanical Methods

In a previous paper various quantum mechanical methods were applied to difluoromethane in order to find a suitable path to accurate ideal gas heat capacities. Now, these calculations are extended to all fluorochloro-derivatives of methane. Reliable experimental heat capacity data reveal that the combination of quantum mechanics and statistical thermodynamics facilitates a prediction of ideal gas heat capacities with an accuracy of ±1% and better. This is very close to the range of accuracy, which is observed for the best experimental zero pressure heat capacity data from different sources of the literature.     

Analysis of Hourly Demand Data before and after the 2011 Tohoku Earthquake

On March 11, 2011, the power system suffered heavy damage from the huge earthquake and tsunami in the Tohoku region. This paper describes the change of features included in the time series of open demand data for the disaster of 3/11/2011. The demand data are separated into three sections: one for the “predisaster” analysis from April 2008 to February 2011, the second for the “during‐disaster” survey from March to May 2011, and the last for the “postdisaster” analysis from June 2011 to March 2013. We distinguished the periodic components of daily, weekly, and seasonal fluctuation among the demand time series by applying a newly developed procedure, the quasi‐ideal moving average method. Some significant changes were observed in the statistics of the predisaster and postdisaster periodic component analysis. The change in temperature sensitivity was also surveyed by using open weather data for Sendai.
