Abstract The objective of this work was to verify if there is variability in the dry matter accumulation rate grains carioca-type common bean, as well identify success selection for trait and best time harvest. Sixteen lines with were evaluated three sowing seasons through samples five plants obtained at regular intervals. A quadratic equation used estimate number days obtain maximum grains. lo...

Slotted multichannel ALOHA is the access scheme of choice for short messages and for reserving channels for longer ones in many satellite-based networks. This paper proposes schemes for increasing the capacity (maximum attainable throughput) of multichannel slotted ALOHA subject to meeting a user-specified deadline with a (high) required probability, thereby jointly capturing the users’ require...

Background and Purpose—To determine the importance of emboli not trapped by carotid angioplasty filtration devices, we examined fragments 100 m released with ex vivo angioplasty and asked if fragment composition and size correlated with brain injury. Methods—Human carotid plaques (21) were excised en bloc, and ex vivo carotid angioplasty was performed. Eight plaques were selected as either high...

Fragment-based quantum chemistry methods are a promising route towards massively parallel electronic structure calculations in large systems. Unfortunately, the literature on this topic consists of a bewildering array of different methods, with no clear guiding principles to choose amongst them. Here, we introduce a conceptual framework that unifies many of these ostensibly disparate approaches...

The 2019 coronavirus disease (COVID-19) pandemic has had an unprecedented impact on health and economies around the world. Direct myocardial injury cytokine storm, leading to destabilization of preexisting plaques accelerated formation new plaques, are two mechanisms that trigger acute coronary syndrome in COVID-19. There is insufficient data immune status patients with who have undergone aim s...
