Introduction: With the emergence of COVID-19, many primary care offices closed their physical space to limit exposure. Despite decades telemedicine in clinical practice, it is rare find used small-metro and academic settings. Following decision face-to-face care, we tracked our practice’s transition telemedicine. Methods: This was a prospective quality improvement project foll...

We present a higher-twist production mechanism for η c and χ J charmonium at large momentum fraction x F in pion-nucleon collisions. The higher-twist contribution is essentially independent of x F and therefore becomes dominant at large x F , where the leading-twist contribution falls off as (1 − x F) 3. We show that the higher-twist mechanism produces longitudinally polarized χ 1 and χ 2. For ...

background: to determine the prevalence and characteristics of birth defects in perinatal infants in hubei province during 200l-2008. methods: the prevalence of birth defects in perinatal infants delivered after 28 weeks or more was analyzed in hubei surveillance hospitals during 200l-2008. results: the incidence of birth defects in perinatal infants from 200l to 2008 was 120.0 per 10,000 birth...

where χ, ψ is a non trivial character of Fq , whose value at 0 is defined to be 0. It is well known that the absolute value of J(χ, ψ) is √ q = p, when χψ is not principal. According to [11], [9], call the Jacobi sum J(χ, ψ) pure if J(χ, ψ)/p is a root of unity. Let ord(χ) be the order of χ in F̂×q . From now on in this paper, we assume that ord(ψ) = 2 and ord(χ) = n ≥ 3. This special type of Ja...
