The verbal transmission of visual information: An experimental study

The aim of this exploratory study is to show how visual information is verbally transmitted in an experimental task. The overall theoretical framework adopted is a modification of Chafe 1994. An experiment was designed in which a drawer was assigned the task of reproducing a stimulus picture relying only on verbal information provided by a describer. No visual contact was allowed between the subje

Effects of ethanol on the expression of immediate-early genes in nerve cells

Immediate-early genes of the fos and jun families encode proteins that dimerize to form a complex of activator protein 1 and regulate the expression of a number of genes in the nervous system. Ethanol has previously been shown to induce alterations in expression of fos and jun genes in the brain. The present study examined the effects of ethanol on the expression of c-fos, fosB, c-jun, junB and ju

Low-complexity ultrawideband transceiver with compatibility to multiband-OFDM

We present a low-complexity transceiver for ultrawideband communications with moderate (1-15 Mbit/s) data rate. This transceiver is based on time-frequency-interleaved frequency-shift-keying (TF-FSK), and shows a high degree of compatibility with multiband-OFDM, the currently envisioned standard for high-data-rate (>100 Mbit/s) UWB communications. We show that for dual-mode devices, the major part

Entrepreneurship in the Age of Big Data: A Researcher's Guide to Data Mining, Inference and Prediction

The bottleneck of Big Data today is the analysis of large amounts of information, including data mining, inference and prediction. Entrepreneurship researchers who want to take advantage of Big Data, need tools and workflows to find important trends and patterns within massive data sets, and understand "what the data tell us." Here, we apply gradient boosting to big, register-based data, and estab

Multi-level coding/modulation using LDPC convolutional codes

In this paper, we propose a novel multilevel coding scheme that employs low-density parity-check convolutional (LDPCC) codes. A combined decoding/ demodulation scheme is also considered. Unlike previous work on multilevel coding, the proposed scheme employs a single code with some structure that allows it to benet from the use of multilevel mapping. The proposed scheme can be seen as a form of bit

Den komplexa vården - om komplexitet och komplexa processer inom hälso- och sjukvården

Hälso- och sjukvården står inför en mängd förändringar och en allt mer komplex och utmanande situation, världen över. Förändringarna sker tvärsektoriellt och på alla plan: Ökad kundfokusering, nya rön om styrning och ledning, forskningsframsteg, ny teknik, ny vårdpraxis, öppna kvalitetsjämförelser, kompetensspecialisering och maktförskjutningar. Förändringarna sker inte bara lokalt utan även regio
