High mutation frequency induced by hybridization [PDF]
, 1939 The increase in variability that is a familiar result of the rearing of second generations from crosses between different races is certainly due chiefly to segregation and recombination of genes in which the parental races differed.

A Compact Maritime Harmonic Radar Antenna for Navigation and Search-and-Rescue
IEEE AccessThis paper presents a compact dual-band dual-polarized slotted waveguide array antenna designed for a maritime harmonic search-and-rescue system. The harmonic radar transmits signals in the S-band and receives clutter-free signals in the C-band through ...

High-frequency microrheology reveals cytoskeleton dynamics in living cells
Nature Physics, 2017 Microrheology of cells suggests that the dynamics of single filaments in the cytoskeleton dominate at high frequencies. This response can be used to detect differences between cell types and states — including benign and malignant cancer cells.

Removing high-frequency oscillations
Neurology, 2018 Objective To evaluate the use of interictal high-frequency oscillations (HFOs) in epilepsy surgery for prediction of postsurgical seizure outcome in a prospective multicenter trial. Methods We hypothesized that a seizure-free outcome could be expected in

A High Frequency Assessment of the ECB Securities Markets Programme
Social Science Research Network, 2017 Policy impact studies often suffer from endogeneity problems. Consider the case of the ECB Securities Markets Programme. If Eurosystem interventions were triggered by sudden and strong price deteriorations, looking at daily (or weekly) price changes may ...

Using low frequency information for predicting high frequency variables
International Journal of Forecasting, 2018 We analyze how to incorporate low frequency information in models for predicting high frequency variables. In doing so, we introduce a new model, the reverse unrestricted MIDAS (RU-MIDAS), which has a periodic structure but can be estimated by simple ...
