We present magnetization measurements on the single-molecule magnet Fe8 in the presence of pulsed microwave radiation. A pump-probe technique is used with two microwave pulses with frequencies of 107 and 118 GHz and pulse lengths of several nanoseconds to study the spin dynamics via time-resolved magnetization measurements using a Hall probe magnetometer. We find evidence for short spin-phonon ...

The percentage of pts switching from 1st gen TKI in line to 3rd 2nd seems be low with 30% and it is questionable whether these data represent real world treatments. Therefore, we investigated the treatment pattern especially attrition rate between therapy EGFR mt+ pts. 965/1536 (63%) non-squamous NSCLC IV were tested for mt+. 148/965 (15%) an identified. To calculate PFS OS used Kaplan Meier lo...

Activated carbon can adsorb and desorb gas molecules onto and off its surface. Research has examined whether this sorption affects low frequency sound waves, with pressures typical of audible sound, interacting with granular activated carbon. Impedance tube measurements were undertaken examining the resonant frequencies of Helmholtz resonators with different backing materials. It was found that...

The FCC has proposed that the unassigned frequencies between broadcast TV channels – the TV band “white space” – should be opened on an unlicensed basis to certified devices that could offer a range of wireless services to the public. Access to the vacant TV channels in each market has been the subject of intense lobbying, yet far too many of the arguments against white space devices rely upon ...

STUDY OBJECTIVES To determine whether the likelihood of lung nodule calcification can be predicted from nodule size as measured on a chest radiograph (CXR). DESIGN Retrospective review of CXRs of patients with lung nodules < or =1 cm in size detected on CT scanning. CT images were used to identify calcifications and to provide spatial localization for readers to visualize nodules on a CXR and...
