This paper presents some aspects related to the issues of aggregating economic indicators. Departing from the research of Gh. Paun (1983) we will prove a theorem which states that under certain, natural assumptions, it is impossible to obtain an optimum aggregation. Unlike the original work of Paun, in this paper we are giving a rather simple proof of this theorem.

The validity of the Michaelis-Menten-Briggs-Haldane approximation for single enzyme reactions has recently been improved by the formalism of the total quasi-steady-state approximation. This approach is here extended to fully competitive systems, and a criterion for its validity is provided. We show that it extends the Michaelis-Menten-Briggs-Haldane approximation for such systems for a wide ran...

In December 2003, seventeen years after the first UK research assessment exercise, Italy started up its first-ever national research evaluation, with the aim to evaluate, using the peer review method, the excellence of the national research production. The evaluation involved 20 disciplinary areas, 102 research structures, 18,500 research products and 6,661 peer reviewers (1,465 from abroad); i...

Ameisen: Die heimliche Weltmacht (Ants: Nature's Secret Power) is a nature documentary about ants. Wolfgang Thaler wrote, filmed, and directed the film, which focuses on the work of ant researcher Bert Hölldobler. The 2004 film was produced by Adi Mayer Film for Österreichischer Rundfunk (Austrian Broadcasting), a public service broadcaster headquartered in Vienna, Austria. Ants: Nature's Secre...

the aim of this paper is to develop a rapid, and highly sensitive quantitative hplc fingerprint method with multiple indicators by using the compound chinese medicine wuwei changyanning granule and 5 herbs in the prescription. the quantitative fingerprint chromatogram with multiple indicators was investigated. ⅰ)6 compositions included rutin, gallic acid, chlorogenic acid, atractylenolideⅰ, pac...

Game makers even want to use the technology to improve the development process. “There has been an almost tectonic shift in the way AI is viewed in the industry,” noted Dave Mark, owner, president, and lead designer of Intrinsic Algorithm, a developer of entertainment and recreation software and services. “Ten years ago,” he explained, “AI in games was largely an afterthought. Since that time, ...

We present a structured matrix factorization approach to analyzing calcium imaging recordings of large neuronal ensembles. Our goal is to simultaneously identify the locations of the neurons, demix spatially overlapping components, and denoise and deconvolve the spiking activity of each neuron from the slow dynamics of the calcium indicator. The matrix factorization approach relies on the obser...
