Spatial frequency response of an optical heterodyne receiver [PDF]

open access: yes
The principles of transfer function analysis are applied to a passive optical heterodyne receiver to obtain the modulation transfer function (MTF). MTF calculations are performed based on an optical platform which is imaging vertically varying profiles ...

Exact design solutions for photodiode transimpedance amplifiers based on FET input OP-AMPs [PDF]

open access: yes, 2002
We calculate the transfer function of an optical receiver composed by a photodiode and a FET input operational amplifier as a current to voltage converter.

The Fate (Outcome) of Clinically Apparent Single Lesion and Oligofocal Nephroblastomatosis Treated According to SIOP/GPOH Protocols for Wilms Tumor

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background The management of clinically apparent single lesions or oligofocal nephroblastomatosis, a facultative precursor of nephroblastoma, remains debated. Methods We retrospectively analyzed 37 patients with clinically apparent single or oligofocal nephroblastomatosis (two to three lesions per kidney) among 2347 patients registered between

Three‐dimensional Moho topography in Italy: New constraints from receiver functions and controlled source seismology

open access: yesGeochemistry, Geophysics, Geosystems, 2011
In complex tectonics regions, seismological, geophysical, and geodynamic modeling require accurate definition of the Moho geometry. Various active and passive seismic experiments performed in the central Mediterranean region revealed local information on

Multichannel telemetry system [PDF]

open access: yes, 1973
A two-channel telemetry system is described in which one channel is used for high-rate data and the other channel for low-rate data communication. In the transmitter a signal, which subsequently phase modulates a carrier, is produced which is a function ...

Inpatient Food Insecurity and Pediatric Hematology Oncology Hospitalization Outcomes

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Children with cancer and blood disorders are at risk for food insecurity (FI). We aimed to describe the association of inpatient food insecurity (IFI) and hospitalization outcomes among patients admitted to the pediatric hematology oncology service. Of 325 caregivers screened for IFI, 60 (18.6%) screened positive.
