Cryptographic hash functions play a central role in cryptography. Hash functions were introduced in cryptology to provide message integrity and authentication. MD5, SHA1 and RIPEMD are among the most commonly used message digest algorithm. Recently proposed attacks on well known and widely used hash functions motivate a design of new stronger hash function. In this paper a new approach is prese...

Bibliometricians are aware that the citation behavior of scientists varies across fields, and for this they carefully normalize citations by field. They are also aware of the different publication intensities across fields. This imposes that the research performance of a scientist must be compared with that of their colleagues in the same field. Every comparison of scientists in different field...

CONTEXT Aphasia is a very disabling condition caused by neurological diseases. In Brazil, we have little data on the profile of aphasics treated in rehabilitation centers. OBJECTIVE To present a descriptive study of 192 patients, providing a reference sample of speech and language disturbances among Brazilians. DESIGN Retrospective study. SETTING Speech Pathology Unit linked to the Neurol...

The decision on whether analyze a time series in levels or differences is an important aspect of forecasting. Visual methods have been around for a long time. Relatively recently, statistical tests for the null hypothesis that the series is nonstationary, meaning that differencing is required, have been developed. This paper reviews the development of these tests, give motivating examples of wh...

In this paper we examine the strength of AES against the related-key impossible differential attack, following the work of Jakimoski and Desmedt [12]. We use several additional observations to substantially improve the data and time complexities of their attacks. Amongst our results, we present a related-key attack on 7-round AES-192 with data complexity of 2 chosen plaintexts (instead of 2). O...

PURPOSE The Dunning R3327-MLL is a well established transplanted tumour line, and as such it makes a desirable model for evaluative studies of therapy. In the current study, the interstitial growth characteristics as well as the response of this tumour to a single fraction of high dose rate radiation is investigated. MATERIALS AND METHODS The in vitro response to radiation of the Dunning R332...

Radiographic images can provide quantitative as well as quantitative information if they are subjected to densitometric analysis. Digital radiography consists of four major steps which include X-ray detection, digitization, image processing and display. The digitization process varies from device to device and may suffer variations even when the same digital equipment is used throughout time. A...

BACKGROUND Several clinical trials indicate that intracoronary radiation is safe and effective for treatment of restenotic coronary arteries. We previously reported 6-month and 3-year clinical and angiographic follow-up demonstrating significant decreases in target lesion revascularization (TLR) and angiographic restenosis after gamma radiation of restenotic lesions. The objective of this study...
