We revisit the problem of finding shortest unique substring (SUS) proposed recently by [6]. We propose an optimal O(n) time and space algorithm that can find an SUS for every location of a string of size n. Our algorithm significantly improves the O(n) time complexity needed by [6]. We also support finding all the SUSes covering every location, whereas the solution in [6] can find only one SUS ...

UNLABELLED The paper addresses how nurses can contribute to the consolidation of the Family Health Strategy (FHS) within the Brazilian National Health System (Sistema Único de Saúde - SUS), in the search for professional autonomy. OBJECTIVES To discuss the limitations and possibilities of nursing work in the FHS aimint at the consolidation of the SUS; evaluate the available nursing appointmen...

Tradicionalmente los usuarios han demandado cierto nivel de personalización en los sistemas software para adaptarlos a sus gustos. Con el tiempo se ha incrementado el nivel de integración de estos sistemas en la vida cotidiana de los usuarios, a la vez que han crecido las exigencias de personalización. Hoy en día, con sistemas que envuelven completamente a los usuarios, podemos hablar del conce...

We studied Brazilian policies on mental health with respect to normative, supply and demand and financing aspects. We concluded that the sustainability of innovations in psychiatric reform depends on enhanced financing and integration with primary care community services, on the overall performance of SUS and the reduction of autonomous and exclusive services in primary care. There is high and ...

Underlay cognitive systems allow secondary users (SUs) to access the licensed band allocated to primary users (PUs) for better spectrum utilization with the power constraint imposed on SUs such that their operation does not harm the normal communication of PUs. This constraint, which limits the coverage range of SUs, can be offset by relaying techniques that take advantage of shorter range comm...

—In this paper, we consider multiple primary and multiple secondary users cooperative cognitive radio networks, in which the primary users (PUs) lease a portion of their spectrum to the secondary users (SUs) for some revenue, and in return the SUs play as relays and help forward the data of the Pus in exchange for being granted spectrum opportunities. Both the PUs and SUs aim to maximize their...

This paper considers a cooperative Orthogonal Frequency Division Multiplexing (OFDM)-based cognitive radio network, where the primary system leases a fraction of its subcarriers to the secondary system in exchange for the secondary users (SUs) acting as decode-and-forward relays. Our aim is to determine an fair resource allocation strategy among the primary users and SUs as so to maximize the n...

It is well recognized that visual impairments (VI) worsen individuals' mental condition. However, little is known about the positive aspects including subjective happiness, positive emotions, and strengths. Therefore, the purpose of this study was to investigate the positive aspects of persons with VI including their subjective happiness, positive emotions, and strengths use. Positive aspects o...

User satisfaction is known to be related to quality of healthcare. The aim of this study was to evaluate the influence of contextual and individual factors associated with user dissatisfaction with the Brazilian Unified National Health System (SUS). This was a cross-sectional multilevel study. Data were collected via telephone by the ombudsman's office of the SUS. Telephone numbers were randoml...

OBJECTIVE The aim of the present scientific study is to evaluate the patterns of antiretroviral technology adoption by the Brazilian Public Health System (SUS). METHODS Based on previous articles published in scientific medical literature, three indicators to assess antiretroviral technology adoption by SUS were proposed: knowledge-adoption interval; critical mass of knowledge; and validation...
