Gills of the seawater fi sh Cat/w raps spixii (Agassiz, 1829) were submitted to routine processing for observation in scanning and transmission electron microscopy. The wrinkled surface of the gill filaments showed well-defined cellular ultrastructures. Microridges on cellular surface were projected over all gi ll structures, including respiratory lamellae. Chloride cells were usually at primar...

In this work we extend previous results on moment-based characterization and minimal representation of stationary Markovian arrival processes (MAPs) and rational arrival processes (RAPs) to transient Markovian arrival processes (TMAPs) and Markovian binary trees (MBTs). We show that the number of moments that characterize a TMAP of size n with full rank marginal is n2+2n−1, and an MBT of size n...

Abstract— A Radio over Fiber (RoF) distribution network based on single-mode fiber (SMF) and a combination of coherence multiplexing (CM) and subcarrier multiplexing (SCM) is proposed. CM is a relatively unknown and potentially inexpensive form of photonic code-division multiplexing, and is used here as a means to distinguish between the radio access points (RAPs). Two alternative CM network to...

We describe an unconventional line of attack in our quest to teach machines how to rap battle by improvising hip hop lyrics on the fly, in which a novel recursive bilingual neural network, TRAAM, implicitly learns soft, context-dependent generalizations over the structural relationships between associated parts of challenge and response raps, while avoiding the exponential complexity costs that...

The rapid increase of dimensions and complexity of real life problems makes it more difficult to find optimal solutions by traditional optimization methods. This challenge requires intelligent and sophisticated algorithms to make the right decisions given a set of inputs and a variety of possible actions. In the problem solving arena, this definition is transformed into the term of artificial i...

ABSTRACT The connection between mental health and work has a long trajectory, often involving oppression restriction of freedom. Seeking new place for users the Psychosocial Care Network (RAPS), solidarity economy been highlighted as multiple possibility in fight against stigma, emphasizing people’s autonomy emancipation through cooperativism. Thus, this article aims to bring an interprofession...

Plants need oxygen, but they don’t always get enough of it. Under waterlogging or other hypoxic conditions, oxygen is not available to act as an electron acceptor in the oxidative phosphorylation pathway. ATP production plummets, depriving the plant of the energy it needs to survive. Fortunately,many plants have developed strategies to help them endure short bouts of hypoxia. By switching to an...
