Abstract Mosquito community dynamics in urban areas are influenced by an array of both social and ecological factors. Human socioeconomic factors (SEF) can be related to mosquito abundance diversity as development sites modified varying human activity, e.g., level abandoned structures or amount accumulated trash. The goal this study was investigate the relationships among diversity, populations...

We have studied 46 patients to compare the efficacy of the auditory evoked potential (AEP) index, bispectral index (BIS), 95% spectral edge frequency (SEF) and median frequency (MF) in predicting movement in response to insertion of the laryngeal mask airway (LMA). Anaesthesia was induced with target-controlled infusions of propofol and alfentanil. After loss of eyelash reflex and adequate jaw ...

Multi-service traffic has a strong impact in Mobile Broadband Systems (MBS) revenues, allowing one to obtain merit functions for optimisation purposes. A ‘net cost’ model is presented for the design trade-offs between re-use pattern, K, the coverage distance, R, and the spectral efficiency, Sef(R). It allows for the determination of the revenue per basic channel, R384, that achieves a given val...

When experimenting with different graphics algorithms and their effects one has to write a lot of code in order to fully exploit today’s graphics hardware. Over the last years there have been some attempts to provide support for this recurring task. A well known example is the nVidia Effect Browser, which can be used as a testbed for numerous purposes. However it provides only limited support w...

This paper considers knowledge management functions as carried out by distributed virtual teams involved in the compilation of information-based products using dedicated and domain-specific computermediated practices and tools. We are concerned with two primary tasks, namely depositing shared assets and assembling information-based artefacts by appropriating the benefits of virtual networking. ...

Using event-related fMRI, we analyzed the functional neuroanatomy of covert reorienting and inhibition of return (IOR). Covert reorienting to a target appearing within 250 msec after an invalid contralateral location cue elicited increased activation in the left fronto-polar cortex (LFPC), right anterior and left posterior middle frontal gyrus, and right cerebellum, areas that have previously b...

Abstract Surface-enhanced spectroscopies, such as surface-enhanced Raman scattering (SERS), fluorescence (SEF), circular dichroism, etc., are powerful tools for investigating nano-entities with high sensitivities. Owing to the giant local electric field confined in a plasmonic nanogap, nanogap-enhanced spectroscopies could detect samples ultralow concentrations, even down single-molecule level ...
