Many senrice courses in statistics, in my experience, have degenerated into the presentation of a set of recipes. The prevailing situation extant in many courses was summed up recently by my son, himself a trainee engineer, when he said, "I lean the recipes to pass the exam but I don't really understand the material". In fact the rapidity with which the material in his course has been presented...

The running time is O(r log n). It can be shown by elementary means that the required r exists in O(log n). So the running time is O(log n). Moreover, by Fouvry’s Theorem [8], such r exists in O(log n), so the running time becomes O(log n). In [10], Lenstra and Pomerance showed that the AKS primality test can be improved by replacing the polynomial x − 1 in equation (1.1) with a specially const...

Chikungunya virus is a mosquito-borne emerging pathogen that has a major health impact in humans and causes fever disease, headache, rash, nausea, vomiting, myalgia, and arthralgia. Indigenous to tropical Africa, recent large outbreaks have been reported in parts of South East Asia and several of its neighboring islands in 2005-07 and in Europe in 2007. Furthermore, positive cases have been con...

As Charlton (1991, p.129) notes, to understand a thinker‟s finitism it is important to understand what kinds of infinity she rejects. Moreover, as I shall argue, to understand Aristotle‟s finitism, it is central to understand not only what kinds of infinity he rejects but also on what grounds he rejects them, for that will allow us to recognize some subtleties of Aristotle‟s account that would ...

OBJECTIVE To compare PRISCUS with Beers-Fick in detecting potentially inappropriate medication (PIMs) in elderly at their first outpatient geriatric visit. METHODS Retrospective medical record analysis by PRISCUS and Beers-Fick adapted to Brazilian pharmacopoeia, comparing the finding of PIMs at the first outpatient geriatric visit by both criteria. RESULTS Cases had mean age of 77.4 ± 7.7 ...

This minireview updates non-exhaustive recent strategies of synthesis of original fluorosurfactants potentially non-biodegradable. Various strategies have been focused on: (i) the preparation of CF3-X-(CH2)n-SO3Na (with X=O, C6H4O or N(CF3) and n=8-12), (ii) the oligomerization of hexafluoropropylene oxide (HFPO) to further synthesize oligo(HFPO)-CF(CF3)CO-RH (where RH stands for an hydrophilic...

We read with interest the paper by Dr Alsaadi and colleagues on ‘‘potentially misleading extratemporal lobe lesions’’ in patients with symptoms of temporal lobe epilepsy. Most of their successfully operated patients with extratemporal lesions also had hippocampal atrophy on the operated side, which has positive prognostic value for mesiotemporal surgery in temporal lobe epilepsy, even in the pr...

Paragangliomas are usually low-grade neoplasms with a benign natural history. While the treatment of paraganglioma has historically been controversial, surgery and radiotherapy have become standardized as therapies of choice for primary therapy. More recently, stereotactic radiosurgery has been used effectively against this rare tumor. The development of metastatic disease in patients with para...

When standard methods of process (black-box) estimation are applied straightforwardly then it may happen that some sets of experimental data result in unphysical estimations of the corresponding channels (maps) describing the process. To prevent this problem, one can use the method of maximum likelihood (MML), which provides an efficient scheme for reconstruction of quantum channels. This schem...
