Consider $\beta > 1$ and $\lfloor \beta \rfloor$ its integer part. It is widely known that any real number $\alpha \in \Bigl[0, \frac{\lfloor \rfloor}{\beta - 1}\Bigr]$ can be represented in base $\beta$ using a development series of the form = \sum_{n 1}^\infty x_n\beta^{-n}$, where $x (x_n)_{n \geq 1}$ sequence taking values into alphabet $\{0,\; ...\; ,\; \lfloor \rfloor\}$. The so called $\...

It is not even clear whether and in what sense it follows that the sentence ‘I am hungry’ is true...

Background Luteinizing hormone (LH) is a heterodimeric glycoprotein composed of alpha and beta subunits.This hormone is secreted from the pituitary gland. LH, in women triggers Menstrual cycle and ovulation. In men, LH stimulates production of testosterone, which plays a specialized role in sperm production. Up to day, LH hormone have produced in different ways such as codon optimization and al...
