This work proposes a novel methodology for estimating the power output of piezoelectric generators. An analytical model that estimates, for the first time, the loss ratio and output power of piezoelectric generators, based on the direct mechanical-to-electrical analogy, electromagnetic theory, and power system theory, is developed and takes into account the dimensions and material properties of...

“Ban-the-Box” (BTB) policies restrict employers from asking about applicants’ criminal histories on job applications and are often presented as a means of reducing unemployment among black men, who disproportionately have criminal records. However, withholding information about criminal records could risk encouraging statistical discrimination: employers may make assumptions about criminality b...

In this Journal we previously reported the predicted SARS-CoV-2 spike-host cell receptor GRP78 binding site (1Ibrahim I.M. Abdelmalek D.H. Elshahat M.E. Elfiky A.A. COVID-19 prediction.J Infect. 2020; 80: 554-562Abstract Full Text PDF PubMed Scopus (343) Google Scholar). New variant VUI 202,012/01 started in UK and currently spreading Europe Australia during last few days. The new bears about n...

ion hierarchy and genetic code Mersenne primes Mn = 2 n − 1, which seem to play fundamental role in elementary particle physics and it has been already found that their emergence is natural consequence of NMP. This would put primes 3, 7, 31, 127, etc. in a special position. Primes appear frequently in various bio-structures and this might reflect the underlying p-adicity for the association seq...

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic represents a global threat, and the interaction between virus angiotensin-converting enzyme (ACE2), primary entry receptor for SARS-CoV-2, is key determinant of range hosts that can be infected by virus. However, mechanisms underpinning ACE2-mediated viral across species remains unclear. Using infection assay, we evaluate...

Groundwater is a vital resource under threat in island communities. Karainagar, 22 km2 island, one of seven islands off the coast Jaffna Northern Sri Lanka, with its population just about 11,000 persons, experiences seasonal water shortage, and salinity groundwater as twin threats impacting on their lives. This paper reports 3-year study (October 2019 to September 2022) map dynamics Karainagar ...

We present the implementation of Distributed Constructionism (DC) through a Participatory Design (PD) methodology for an Online Learning community. The students collaborate on the content and functionality development of an online Modern Greek language course, peer review and publish content contributions, and participate in participatory design teams. Participatory design was implemented as a ...
