We correlate an overlapping period of earthshine measurements of Earth's reflectance (from 1999 through mid-2001) with satellite observations of global cloud properties to construct from the latter a proxy measure of Earth's global shortwave reflectance. This proxy shows a steady decrease in Earth's reflectance from 1984 to 2000, with a strong climatologically significant drop after 1995. From ...

The authorship panel of each article was examined for number of authors, gender, educational degree category, and subspecialty area of publication. Data wer...

We remark that the experimental demonstrations of Shor’s algorithm in the past decades are falsely claimed and flawed, because they had used too less qubits in the first quantum register to accomplish the step of Continued Fraction Expansion in Shor’s algorithm. More worse, the amount of qubits used in some experiments are too less to represent all residues modulo n, which means that the number...

OBJECTIVES Clinico-epidemiological pattern of childhood leprosy in India over the past two decades were analysed from the Indian studies conducted during the years 1990-2009. RESULTS Twelve studies on childhood leprosy were included. Ten were conducted in health institutions and one was a community-based survey. Voluntary reporting was the principal method of case detection; community survey ...
