OBJECTIVES To study the long term tolerance of parenteral gold and subsequent drug treatment in patients with rheumatoid arthritis, including prediction of outcome and 'survival' of sequential treatments. METHODS A retrospective cohort study of 376 patients was made, including a detailed screening of 237 patients treated in 1989. Reasons for discontinuing treatment were analysed in life table...

One of the fundamental challenges for data mining is to enable inductive learning algorithms to operate on very large databases. Ensemble learning techniques such as bagging have been applied successfully to improve accuracy of classification models by generating multiple models, from replicate training sets, and aggregating them to form a composite model. In this paper, we adapt the bagging ap...

Masking is an effective countermeasure against side-channel attacks. In this paper, we improve the efficiency of the high-order masking of look-up tables countermeasure introduced at Eurocrypt 2014, based on a combination of three techniques, and still with a proof of security in the Ishai-Sahai-Wagner (ISW) probing model. The first technique consists in proving security under the stronger t-SN...

Colorimetric reproduction requires calibrated color output devices. One way to characterize a color output device is with a three-dimensional look-up table which maps the tristimulus values, t, to the control values, c of the output device. The functional form of the output device can be written in vector notation as t = F(c). The purpose of calibration is to define an inverse mapping from tris...

The use of Look-Up Tables (LUTs) is extended from binary to multiple-valued logic (MVL) circuits. A multiple-valued LUT can be implemented using both current-mode and voltage-mode techniques, reducing the transistor count to half compared to that of a binary implementation. Two main applications for multiple-valued LUTs are multiple-valued FPGAs and intelligent memories. An FPGA uses a LUT as a...

In this paper, a quick table look-up optimization algorithm is presented to solve the problems of long table look-up time for CAVLC decoding in H.264/AVC. The achievement of the new algorithm rests that we make full use of the hash table query and index technology to improve the table look-up speed for CAVLC decoding. The basic idea of the new algorithm is that we take the number of zero in cod...

In industry, a feedback controller with look-up table (LUT) is often used for nonlinear systems. Although this structure easy to understand, tuning the LUT parameters time-consuming due huge number of parameters. This paper presents direct data-driven design method gain-scheduled directly tune from single-experiment data without system model. Specifically, conventional virtual reference (VRFT),...
