We report the confirmation of a sub-Saturn-size exoplanet,TOI-1194 b,with a mass of about 0.456+0.055-0.051M_(J),and a very low mass companion star with a mass of about 96.5±1.5 MJ,TOI-1251 *** candidates provided by the Transiting Exoplanet Survey Satellite(TESS)are suitable for further follow-up observations by ground-based telescopes with small and medium *** analysis is performed based on data from several telescopes worldwide,including telescopes in the Sino-German multiband photometric campaign,which aimed at confirming TESS Objects of Interest(TOIs)using ground-based small-aperture and medium-aperture telescopes,especially for long-period ***-1194 b is confirmed based on the consistent periodic transit depths from the multiband photometric *** measure an orbital period of 2.310644±0.000001 days,the radius is 0.767+0.045-0.041RJ and the amplitude of the RV curve is 69.4_(-7.3)^(+7.9)m s^(-1).TOI-1251 B is confirmed based on the multiband photometric and high-resolution spectroscopic data,whose orbital period is 5.963054+0.000002-0.000001days,radius is 0.947+0.035-0.033 R_(J) and amplitude of the RV curve is 9849_(-40)^(+42)ms^(-1).

Market-oriented housing reforms and the rapid urbanization process have led to spectacular growth in the Chinese real estate sector(RES).However,the changes in the role played by this sector in the structural dynamics of the Chinese economy have not been examined ***,we analyze the intersectoral structural changes to the Chinese RES,its linkages with the rest of the economy,and its growth sources,using four Chinese input-output tables from 2002 to *** depart from existing work on the RES by using the causative matrix approach and structural decomposition analysis,and obtain three main ***,the RES,which received little non-RES feedback during the 2002-2007period,has subsequently received much more substantial ***,the impact of the RES on China s economic growth stems mainly from its forward ***,the growth in the RES has been driven mainly by domestic demand *** results highlight that the Chinese RES,which plays a key role in value chains,is highly dependent on its own final demand and a fall in its demand would impede economic *** important implication of these results is that developing the national economy by stimulating the RES would not be as effective as developing the RES through stimulating the national economy.
