Following Bass–Milnor–Serre, we prove that SLn(Z) has the congruence subgroup property for n ≥ 3. This was originally proved by Mennicke and Bass–Lazard–Serre. Let Γn = SLn(Z). The congruence subgroup problem for Γn (solved independently by Mennicke [Me] and Bass–Lazard–Serre [BLS]) seeks to classify all finite-index subgroups of Γn. For l ≥ 2, the level l principal congruence subgroup of Γn, d...

In the course of the WedelMusic project [15], we are currently implementing retrieval engines based on musical content automatically extracted from a musical score. By musical content, we mean not only main melodic motives, but also harmony, or tonality. In this paper, we first review previous research in the domain of harmonic analysis of tonal music. We then present a method for automated har...

A cost-effective b[combining low line]a[combining low line]ttery-powered s[combining low line]pectrophotometric s[combining low line]ystem (BASS) was developed for quantitative point-of-care (POC) analysis on a microfluidic chip. By using methylene blue as a model analyte, we first compared the performance of the BASS with a commercial spectrophotometric system, and further applied the BASS for...

This paper describes a robust method for estimating the fundamental frequency (F0) of melody and bass lines in monaural realworld musical audio signals containing sounds of various instruments. Most previous F0-estimation methods had great difficulty dealing with such complex audio signals because they were designed to deal with mixtures of only a few sounds. To make it possible to estimate the...

We consider the diffusion of new products in social networks, where consumers who adopt the product can later “recover” and stop influencing others to adopt the product. We show that the diffusion is not described by the SIR model, but rather by a novel model, the Bass-SIR model, which combines the Bass model for diffusion of new products with the SIR model for epidemics. The phase transition o...

In this paper, we compare two approaches for automatic classification of bass playing styles, one based on highlevel features and another one based on similarity measures between bass patterns. For both approaches, we compare two different strategies: classification of patterns as a whole and classification of all measures of a pattern with a subsequent accumulation of the classification result...

We analysed 34 Vibrio alginolyticus strains isolated from gilthead sea bream Sparus aurata L. and sea bass Dicentrarchus labrax L. cultured in fish farms on the Tunisian Mediterranean coast for the presence of several virulence properties such as extracellular products (ECP) production, growth in iron-limiting conditions and survival in fish serum. The results obtained with different substrates...

Aim In clear, cold-water lakes, ultraviolet radiation (UV) and temperature are two important stressors that may prevent the establishment of aquatic invasive species by inhibiting the survival of sensitive early life history stages. In this study, we develop a UV–temperature response model to predict the establishment potential of a warmwater fish, largemouth bass (Micropterus salmoides), in a ...

We address Bass’ question, on whether Kn(R) = Kn(R[t]) implies Kn(R) = Kn(R[t1, t2]). In a companion paper, we establish a positive answer to this question when R is of finite type over a field of infinite transcendence degree over the rationals. Here we provide an example of an isolated surface singularity over a number field for which the answer the Bass’ question is “no” when n = 0.
