Selecting a committee that meets diversity and proportionality criteria is challenging endeavor has been studied extensively in recent years. This task becomes even more when some of the selected candidates decline invitation to join committee. Since unavailability one candidate may impact rest selection, inviting all at same time lead suboptimal Instead, invitations should be sequential condit...

Here we present eight new candidates for exoplanets detected by the transit method at Special Astrophysical Observatory of Russian Academy Sciences. Photometric observations were performed with a 50-cm robotic telescope during second half 2020. We transits depths $\Delta m = 0.056-0.173^m$ and periods $P 18.8^h-8.3^d$ in light curves stars magnitudes $m 14.3-18.8^m$. All considered are classifi...

We consider, in general terms, the possible parameter space of thermal dark matter candidates. assume that particle is fundamental and was equilibrium a hidden sector with temperature ${T}^{\ensuremath{'}}$, which may differ from Standard Model temperature, $T$. The candidates lie region ${T}^{\ensuremath{'}}/T$ vs. ${m}_{\mathrm{dm}}$ plane, bounded by both model-independent theoretical consid...

Abstract Voters often face a complex information environment with many options when they vote in elections. Research on democratic representation has traditionally been skeptical about voters’ ability to navigate this complexity. However, voting advice applications (VAAs) offer voters shortcut compare their own preferences across numerous issues those of large number political candidates. As VA...
