Over the years it has been an important goal to optimize the treatment of subfertility in order to obtain a better pregnancy rate and baby-take-home rate, usually combined with the goal of decreasing the rate of multiplet pregnancies. This implies optimizing the development of embryos through improved in vitro culture methods. And it also implies optimizing the methods of selection of embryos f...

We have carried out the first spectro-polarimetric study of bright NS-LMXB GX 9+9 using IXPE and AstroSat observations. report a significant detection polarization $1.7\pm 0.4\%$ over $2-8$ keV energy band, with angle $63^{\circ}\pm 7^{\circ}$. The is found to be energy-dependent, $3\sigma$ degree consistent null in $2-4$ keV, $3.2\%$ $4-8$ keV. Typical spectra seen NS-LMXBs, we find that combi...
