In this study, the host-guest behavior of poly(amidoamine) (PAMAM) dendrimers bearing amine, hydroxyl, or carboxylate surface functionalities were investigated by paramagnetic NMR studies. 2,2,6,6-Tetramethylpiperidinyloxy (TEMPO) derivatives were used as paramagnetic guest molecules. The results showed that TEMPO-COOH significantly broaden the ¹H NMR peaks of amine- and hydroxyl-terminated PAM...

The data reported in this paper are complementary to the characterization of 4-(phenylazo)-benzoyl-2,2,6,6-tetramethylpiperidine-1-oxyl radical (AzO-TEMPO) and of the 4-(2-thienylazo)-benzoyl-2,2,6,6-tetramethylpiperidine-1-oxyl radical (ThiO-TEMPO) before and after their grafting to two polyethylene matrices (a copolymer ethylene/α-olefin (co-EO) and a high density polyethylene (HDPE)). Partic...

Tempo variations in classical music are an important means of artistic expression. Fluctuations in tempo can be large and sudden, making applications like automated score following a challenging task. Some of the fluctuations may be predicted from (tempo annotations in) the score, but prediction based only on the score is unlikely to capture the internal coherence of a performance. On the other...

To be regarded as environmentally friendly and economical, an industrial process using 2,2,6,6-tetramethylpiperidine 1-oxyl (TEMPO) oxidation requires recycling and/or recovery of chemicals. In this work, hypochlorite recycling via electrolysis was evaluated and potential means for TEMPO recovery were explored. The most important variable affecting electrochemical hypochlorite conversion was th...

There are manyMIR applications for which we would like to be able to determine the perceived tempo of a song automatically. However, automatic tempo extraction itself is still an open problem. In general there are two tempo extraction methods, either based on the estimation of interonset intervals or based on self similarity computations. To predict a tempo the most significant time-lag or the ...

How can the sluggish, long-wavelength mantle convection be expressed by so many time and space scales of morphotectonic activity? To investigate these relationships, we explore Java-Banda subduction zone, where geodynamic records cluster. In far-East Tethys, exceptionally arcuate Banda zone circumscribes deepest oceanic basin on Earth, seismotectonic activity slices upper plate more efficiently...

This paper addresses the problem of determining tempo and timing data from a list of beat annotations. Whilst an approximation to the tempo can be calculated from the inter-beat interval, the annotations also include timing variations due to expressively timed events, phase shifts and errors in the annotation times. These deviations tend to propagate into the tempo graph and so tempo analysis m...

We study a one-dimensional sluggish random walk with space-dependent transition probabilities between nearest-neighbour lattice sites. Motivated by trap models of slow dynamics, we consider model in which the depth increases logarithmically distance from origin. This leads to has symmetric that decrease $|k|$ origin as $1/|k|$ for large $|k|$. show typical position after time $t$ scales $t^{1/3...

BACKGROUND Since accumulating evidence suggests that step rate is strongly associated with running-related injuries, it is important for runners to exercise at an appropriate running cadence. As music tempo has been shown to be capable of impacting exercise performance of repetitive endurance activities, it might also serve as a means to (re)shape running cadence. The aim of this study was to v...
