UNDERSTANDING THE IMPACT OF THE COVID-19 PANDEMIC ON U.S. OLDER ADULTS: SELF-REPORTED PANDEMIC-RELATED CONCERNS AND CONSEQUENCES IN A CROSS-SECTIONAL SURVEY STUDY

Background and objectivesThe purpose of this study was to explore COVID-19 pandemic-related concerns among a racially and ethnically representative sample of older adults in the U.S.Research design and methodsParticipants were 501 English-speaking adults 60 years and older recruited online nationally across the U.S.from Amazon Mechanical Turk (mT

This study highlights the major players in the global food balance, potential implications of COVID-19 on global food supply, and SDG-2 (zero hunger).It found that developing countries, fifteen from Africa followed by ten from Latin America, six Dishwashers from Oceania, and four from Asia, are the most vulnerable to changes cereal supply shocks.It

In this paper, we are interested in the in vivo detection of pre-cancerous stomach lesions.Pre-cancerous lesions are unfortunately rarely explored in research papers as most of them are focused on cancer detection or conducted ex-vivo.For this purpose, a novel prototype is introduced.It consists of a standard endoscope with multispectral cameras, a

Eigenvalue-based algorithm is generally acknowledged to be a promising method for spectrum sensing.However, it possesses FULL ZIP HOODIES high computational complexity, because the sampled covariance matrix and the corresponding eigenvalues are calculated.Furthermore, the detection performance of eigenvalue-based algorithms experiences a huge decli
