Depression is one of the costliest and most disabling illnesses worldwide ( World Health Organization, 2018 Organization Depression. https://www.who.int/news-room/fact-sheets/detail/depressionDate: Google Scholar ). The (WHO) estimates that over 350 million people are affected by depression, leading to 800,000 suicides each year Major depression symptoms include memory loss, lack focus, irritab...

Numerous studies have demonstrated the efficacy of CPAP therapy for reducing symptoms (eg, daytime sleepiness), improving quality of life (QOL), reducing the risk of driving and occupational accidents, and preventing sequelae of obstructive sleep apnea (OSA), such as cardiovascular morbidity and mortality.1-3 Many patients have trouble complying with CPAP therapy even though it is effective.4 A...

In this paper the development of a questionnairebased usability evaluation method for e-learning applications is described. The method extends the current practice by focusing not only on cognitive but also affective considerations that may influence e-learning usability. The method was developed according to an established methodology in HCI research and relied upon a conceptual framework that...

Wasim Maziak Syria Of all its accomplishments, the West is perhaps most proud of its scientific revolution, which has been unfolding for the past halfmillennium. Only students of history remain consistently mindful of the pivotal and catalytic role that the Arab world played in the early phases of this revolution. Now, all of us should have a vested interest in advancing science and technology ...

We read with interest Saigal et al’s (1) article, MR Findings of Cortical Blindness Following Cerebral Angiography, in the February 2004 issue of the AJNR. The authors reported MR imaging findings in three cases of cortical blindness following cerebral angiography in which nonionic contrast media were used. These cases exhibited clinical and radiological findings that were relatively similar to...

Making materials that display angle-independent structural color requires control over both scattering and short-range correlations in the refractive index. We demonstrate a simple way to make such materials by packing core-shell colloidal particles consisting of high-refractive-index cores and soft, transparent shells. The core-shell structure allows us to control the scattering cross-section ...

In a recent publication, “Reliability of a commercial kit to test groundwater for arsenic in Bangladesh” (1) regarding the effectiveness of the Hach EZ arsenic kit (product 2822800), Van Geen et al. remarked “Clearly the Hach kit should continue to be used to test wells throughout Bangladesh and other countries affected by elevated arsenic in groundwater”. They studied only 799 wells in a 25-sq...

The transition rate of the stimulated emission at the higher energy levels of the excited states in a silica-based erbium-doped fiber can be enhanced by introducing fundamental-mode cutoff filtering mechanism. The electrons excited by optical pumping can more occupy the higher energy levels of the excited states when the transition rate for the lower energy levels (longer wavelengths) of the ex...

This issue contains 10 papers. In the first paper, Diego Mazala and Claudio Esperança, from Universidade Federal do Rio de Janeiro in Brazil, Ricardo Marroquim, Delft University of Technology Netherlands, present a novel method for blending human faces order to create new one. nutshell, their proposal uses Laplacian smoothing segregate layers details one or more faces, which are then integrated...
