Flexible receiver for multiband orthogonal frequency division multiplexing signals at the millimeter waveband based on optical downconversion.

A novel (to our knowledge) and flexible photonics-based downconversion scheme is proposed for wireless receivers in base stations. It allows simultaneous detection of multiple signals at carriers up to tens of gigahertz, enabling communications at millimeter waves. Experiments demonstrate the effective downconversion of Wi-Fi signals at 2.4 and 39.8 GHz with the error vector magniture <-43 dB.

[Two cases of familial thyroxine-binding globulin (TBG) deficit identified by the screening of neonatal hypothyroidism (author's transl)]. / Due casi di deficit familiare di thyroxine-binding globulin identificati nel corso dello screening neonatale per l'ipotiroidismo.

Thyroxine-binding globulin deficiency is a well-known condition transmitted as a X-linked dominant trait or as autosomal dominant trait. This condition is benign and hypothyroidism is never associated. Values of T4 in the serum are abnormally low, TSH values are normal, RT3U values are high. TBG deficiency probably are much more diffuse than we believed in past. Therefore it's possible to detect this deficit through screening programs for neonatal hypothyroidism. In this paper we describe two cases of TBG deficit. Thyroid function and TBG levels in babies and in their families are studied. In our sample of three years the incidence is I:3170 newborns, The presumable inheritance pattern are both X-linked dominant and autosomal dominant. Neither in affected babies nor in their relatives thyroid function is abnormal.
