Massively Parallel Huffman Decoding on GPUs

2018

Data compression is a fundamental building block in a wide range of applications. Besides its intended purpose to save valuable storage on hard disks, compression can be utilized to increase the effective bandwidth to attached storage as realized by state-of-the-art file systems. In the foreseeing future, on-the-fly compression and decompression will gain utmost importance for the processing of data-intensive applications such as streamed Deep Learning tasks or Next Generation Sequencing pipelines, which establishes the need for fast parallel implementations. Huffman coding is an integral part of a number of compression methods. However, efficient parallel implementation of Huffman decompre…

Neuromuscular function during drop jumps in young and elderly males

2011

The Hoffman reflex (H-reflex), indicating alpha-motoneuron pool activity, has been shown to be task - and in resting conditions - age dependent. How aging affects H-reflex activity during explosive movements is not clear at present. The purpose of this study was to examine the effects of aging on H-reflexes during drop jumps, and its possible role in drop jump performance. Ten young (26.8 ± 2.7 years) and twenty elderly (64.2 ± 2.7 years) subjects participated in the study. Maximal drop jump performance and soleus H-reflex response (H/M jump) 20 ms after ground contact were measured in a sledge ergometer. Maximal H-reflex, maximal M-wave, Hmax/Mmax-ratio and H-reflex excitability curves wer…

Neuromuscular Adaptations to Short-Term High-Intensity Interval Training in Female Ice-Hockey Players

2019

Kinnunen, J-V, Piitulainen, H, and Piirainen, JM. Neuromuscular adaptations to short-term high-intensity interval training in female ice-hockey players. J Strength Cond Res 33(2): 479-485, 2019-High-intensity interval training (HIIT)-related neuromuscular adaptations, changes in force production, and on-ice performance were investigated in female ice-hockey players during preseason. Fourteen Finnish championship level ice-hockey players (average age 22 ± 3 years) participated in 2½-week HIIT. Both spinal (H-reflex) and supraspinal (V-wave) neuromuscular responses of the soleus muscle were recorded before and after the training period. Static jump (SJ) and countermovement jump heights, plant…

The Myriad Virtues of Wavelet Trees

2009

Wavelet Trees have been introduced in [Grossi, Gupta and Vitter, SODA '03] and have been rapidly recognized as a very flexible tool for the design of compressed full-text indexes and data compressors. Although several papers have investigated the beauty and usefulness of this data structure in the full-text indexing scenario, its impact on data compression has not been fully explored. In this paper we provide a complete theoretical analysis of a wide class of compression algorithms based on Wavelet Trees. We also show how to improve their asymptotic performance by introducing a novel framework, called Generalized Wavelet Trees, that aims for the best combination of binary compressors (like,…

Textual data compression in computational biology: Algorithmic techniques

2012

Abstract In a recent review [R. Giancarlo, D. Scaturro, F. Utro, Textual data compression in computational biology: a synopsis, Bioinformatics 25 (2009) 1575–1586] the first systematic organization and presentation of the impact of textual data compression for the analysis of biological data has been given. Its main focus was on a systematic presentation of the key areas of bioinformatics and computational biology where compression has been used together with a technical presentation of how well-known notions from information theory have been adapted to successfully work on biological data. Rather surprisingly, the use of data compression is pervasive in computational biology. Starting from…

Étranges interactions : Cadrer la communication interculturelle à l'aide de Goffman ?

2015

International audience; Au début de la deuxième moitié du siècle dernier, alors qu'Erving Goffman développait sa réflexion sur la microsociologie des interactions quotidiennes, un anthropologue américain travaillant au service de son gouvernement s'intéressait aux interactions sociales dans différentes sociétés et plus globalement aux différences culturelles et à leur impact sur la communication. Ce contemporain de Goffman, Edward Twitchell Hall, est très souvent présenté comme le fondateur de la communication interculturelle en Occident, dans les ouvrages et les articles qui portent sur ce champ de recherche (Poutiainen 2014, 3). Même si les travaux en communication interculturelle se réfè…

Vedere. Lo sguardo di E.T.A. Hoffmann

2009

Vedere la folla attraverso una serie di inquadrature e con lo sguardo del voyeur, dello spettatore, dello scienziato, del visionario. Vedere la notte in un’oscurità che si popola di presenze inquietanti e sottrae il reale alla vista segnando la crisi della rappresentazione classica. Uno studio a quattro mani sul “vedere” in E.T.A. Hoffmann, corredato da un ricco apparato iconografico, che dimostra la centralità di questo autore sia sul versante di una teoria dello sguardo romantico sia su quello del rapporto tra dispositivi ottici e scrittura letteraria.
