Thisarticle first reviews the history of political science teaching in Europebefore going on to consider a range of recent developments in the teaching of politicalscience, including cross-national joint programmers; technologically enhancedlearning; placement learning and problem-based learning. The last sectionconsiders a range of issues facing political science teachers, includingfinancial p...

The anti-senescence biogenic polyamines (PAs) putrescine (Put), spermidine (Spd) and spermine (Spm) are involved in plant growth processes and responses to stress. The physiological mechanism of exogenous Put to affect the senescence of cut lisianthus flowers during vase life was investigated. Fresh cut lisianthus flowers were treated with distilled water (control), 0.5, 1 and 2 mM Put and then...

objective(s):althoughroutinely applied in assisted reproductive technology, human sperm cryopreservation is not a completely successful procedure. adverse effects of cryopreservation on the fertilization capacity, motility, morphology, and viability of spermatozoa have been proven; cryopreservation has also shown a role in sperm dna fragmentation and infertility. the post-thaw survival of sperm...

Abstract Nanoarchitectonics describes the integration of nanotechnology with other fields as a postnanotechnology concept that elevates it to material science. Based on this fundamental principle, we address pore-engineered nanoarchitectonics application targets for cancer therapy by combining basic descriptions and exemplifying applications in review. The initial two sections briefly summarize...

This article theorizes path-dependent changes in the institutional architecture of nuclear nonproliferation regime complex; it analyses effects different regime-complex structures on contestation and policy adjustment. I first offer a general theory how preexisting international complexes (IRCs) facilitate constrain subsequent developments ways that make IRCs prone to endogenous, change. Next, ...

A procedure for the selection of neural models of dynamical processes is presented. It uses statistical tests at various levels of model reduction, in order to provide optimal tradeoffs between accuracy and parsimony. The efficiency of the method is illustrated by the modeling of a highly non-linear NARX process.

Chaotic time-series is a dynamic nonlinear system whose features can not be fully reflected by Linear Regression Model or Static Neural Network. While Nonlinear Autoregressive with eXogenous input includes feedback of network output, therefore, it can better reflect the system’s dynamic feature. Take annual active times of sunspot as an example, after verifying the chaos of sunspot time-series ...

In this paper, a new correlation analysis based algorithm is proposed for the identification of a class of nonlinear systems which can be described by the NARX (Nonlinear AutoRegressive with eXogeneous input) model with input nonlinearities. Without any assumptions about the structure of an approximating function for the system nonlineariy, the algorithm recovers the functional values of the no...
