measure the capacity to make abstractions, to learn, and to deal with novel situations. Testing of the visual abilities of the shape understanding system (SUS) is performed based on the visual intelligence tests. In this paper the progressive matrices tests are formulated as tasks given to SUS. These tests require good visual problem solving abilities of the human subject. SUS solves these test...

OBJECTIVE Analyze Long Term Care Institutions for Elders (ILPI) organizational social system and its relation to the National Health System (SUS). To identify communication that occurs in the structural couplings between the ILPIs and the SUS and to analyze resonances of the structural coupling between the SUS and the ILPIs. METHOD A descriptive, exploratory qualitative study using the functi...

OBJECTIVE To analyze the differences in health services utilization by users of Brazilian Unified Health System (SUS) and beneficiaries of Supplemental Health (SH). METHODS A total of 288 adult subjects, residing in Belo Horizonte, who participated in the VIGITEL telephone survey in 2009, composed the sample, whose variables were analyzed according to the classification as users of SUS or ben...

The energy-efficient transmissions for multiple-input multiple-output (MIMO) cognitive radio (CR) networks in which the secondary unlicensed users coexist with the primary licensed users. To optimize the time allocations and beam forming vectors for the secondary users (SUs), in order to minimize the energy consumption of the SUs while satisfying the SUs rate requirements and the primary receiv...

BACKGROUND Surgeon-performed ultrasound (SUS) has become an extension of the physical examination in the evaluation of patients with thyroid nodules. Amid concerns that too many "diagnostic" thyroidectomies are performed, this study examines the usefulness of SUS in predicting benign thyroid nodules. METHODS A retrospective review of 624 patients with solitary or dominant thyroid nodules and ...

In this paper, we study the relay-based communication schemes for cooperative spectrum sharing among multiple primary users (PUs) and multiple secondary users (SUs) with incomplete information. Inspired by contract theory, we model the network as a labor market. In this market, PUs and SUs are regarded as employer and employee respectively. Each PU proposes certain contracts to attract the SUs,...

The problem of opportunistic spectrum access in cognitive radio networks (CRNs) is considered in this paper. Especially, we discuss designing distributed learning protocols for non-cooperative secondary users (SUs) to efficiently utilize the spectrum opportunities. It is well known that the SUs’ selfish behaviors will result in a network collapse. Each SU is thus enabled to form conjectures ove...

An allocation of sensing and reporting times is proposed to improve the sensing performance by scheduling them in an efficient way for cognitive radio networks with cluster-based cooperative spectrum sensing. In the conventional cooperative sensing scheme, all secondary users (SUs) detect the primary user (PU) signal to check the availability of the spectrum during a fixed sensing time slot. Th...

Scanning ultrasound (SUS) is a noninvasive approach that has recently been shown to ameliorate histopathological changes and restore memory functions in an Alzheimer's disease mouse model. Although no overt neuronal damage was reported, the short- and long-term effects of SUS on neuronal excitability and dendritic tree morphology had not been investigated. To address this, we performed patch-cl...
