cute myeloid leukemia (AML) is the most frequent acute eukemia of adult patients with an estimated 10,070 new cases n Brazil in 2016. Most of the cases are de novo, without a efined etiology, and around two thirds of the patients will die f the disease, according to the Instituto Nacional de Câncer INCA).1 Genetic aberrations may help to differentiate patients ho have a good from those with a d...

It makes swept insertion and return loss measurements simultaneously, overa wide frequency range. TO THE MICROWAVE ENGINEER, an instru ment that measures insertion and return loss simultaneously, over a broad band, would be as useful as is the voltmeter to other electronic special ists, provided it is made practical in several im portant ways. • Its measurements must really refer to the micro...

Modal Logic is traditionally concerned with the intensional operators \possibly" and \necessary", whose intuitive correspondence with the standard quantiiers \there ex-ists" and \for all" comes out clearly in the usual Kripke semantics. This observation underlies the well-known translation from modal logic into the rst-order language over possible worlds models 12, 13]. In this way, modal forma...

Research) in 1957 with the aim of informing Swedish and Nordic readers about progress in nutritional sciences. It was directed to professionals working with nutrition such as dieticians, nutrition-ists, medical doctors and nurses, teachers of home economics, and not the least the Swedish food industry that was keen on applying new results for nutritional improvements of their products.

The treatment of long-range interacting systems (including Newtonian self-gravitating systems) remains a challenging issue in statistical mechanics. Due to the lack of extensivity, they present non-standard effects like negative specific heats, which shows the inequivalence of statistical ensembles (namely, microcanon-ical and canonical) even in the limit of infinite number of particles (N → ∞)...

urrealism claims totally the work of the enchantress too soon gone, " said André Breton, when he heard that Remedios Varo had died, in 1963 (1). Surrealism, which sought to express " the actual functioning of thought, " was Varo's vehicle for understanding the universe, a vehicle that, like the fanciful locomotives in many of her paintings, went beyond established scientific principles.

H ighlighting this issue of PNAS is a special feature comprising a Perspective and five research articles on the theme of long-range electron transfer. Distant electron transfers play key roles in aerobic respiration and photosynthe-sis, which work in concert: The oxygen that is evolved by photosynthetic organisms is the oxidant that sustains life in aerobic microbes and animals; and, in turn, ...
