Intraspecific variation and trade-off in aerobic and anaerobic traits remain poorly understood in aquatic locomotion. Using gilthead sea bream (Sparus aurata) and Trinidadian guppy (Poecilia reticulata), both axial swimmers, this study tested four hypotheses: (1) gait transition from steady to unsteady (i.e., burst-assisted) swimming is associated with anaerobic metabolism evidenced as excess p...

A scheduling problem that includes different hardware delays experienced by the secondary users (SUs) while switching to different frequency bands in a centralized cognitive radio network (CRN) is formulated. A polynomial-time suboptimal algorithm is proposed to reduce the scheduling problem. The impact of varying switching delay, number offer quencies, and number of SUs is evaluated. The simul...

a percepción computacional (percepción artificial) tiene la finalidad de la reproducción artificial (que engloba subsistemas no informáticos) del sentido de la vista. Se trata de un objetivo excepcionalmente ambicioso y complejo, que se encuentra actualmente en sus inicios, pero que avanza excesivamente rápido. Parece natural pensar que el objetivo de dotar a las máquinas del sentido de la vist...

Traditional beamforming and power control algo-rithms in cognitive radio (CR) are based on the assumption of perfect channel state information (CSI) however; this may lead to performance degradation in realistic systems. In this paper, the problem of joint beamforming and power control is investigated in underlay CR networks with imperfect CSI. Our objective is to maximize the sum utility of se...

Among a number of classes of oral antihyperglycemic drugs, sulfonylureas (SUs) demonstrating the potential effect to reduce blood glucose level have been used in a majority of patients with type 2 diabetes for many years. The pathophysiological processes by which SUs adversely induce the risk of cardiovascular disease have not been fully clarified. We summarized about the relationship between S...

Cognitive Radio (CR) is a promising technique to address the spectrum scarcity issue by enabling the unlicensed network users (SUs) to dynamic access the spectrum holes. This thesis designs Medium Access Control (MAC) protocols for SUs to utilize the unused spectrum without interfering the licensed network users’ (PUs) transmissions; analyzes the MAC performance based on the queuing theories; a...

A sequential updating scheme (SUS) for belief propagation (BP) decoding of LDPC codes over Galois fields, GF (q), and correlated Markov sources is proposed, and compared with the standard parallel updating scheme (PUS). A thorough experimental study of various transmission settings indicates that the convergence rate, in iterations, of the BP algorithm (and subsequently its complexity) for the ...

The purpose of this study was to evaluate the usability of a gamified application (WellWe) among public health nurses (PHN) and families with toddlers and preschool-aged children. A post-test design was used. After providing access to WellWe and using it during one health visit in a child health clinic, data were collected with structured system usability scale (SUS) from PHNs (n=5) and familie...

We propose a distributed spectrum access algorithm for cognitive radio relay networks with multiple primary users (PU) and multiple secondary users (SU). The key idea behind the proposed algorithm is that the PUs negotiate with the SUs on both the amount of monetary compensation, and the amount of time the SUs are either (i) allowed spectrum access, or (ii) cooperatively relaying the PU’s data,...

The paper offers a historical retrospective of Brazil's Sistema Único de Saúde (SUS), including its background and its legacy on its current design. It begins describing some of the system's structural problems, especially the co-existence of a public system alongside a private one. It identifies problems that have hampered a firmer solidification of SUS, while it also highlights the immense im...
