14 15 Autosomal-dominant polycystic kidney disease is a common cause of end-stage renal 16 disease, and no approved treatment is available in the US to slow disease progression. 17 The mTOR signaling pathway is aberrantly activated in renal cysts, and, while mTOR 18 inhibitors are highly effective in rodent models, clinical trials in ADPKD have been 19 disappointing due to dose-limiting extra-r...
Little is known of the consequences of divergent selection for residual feed intake (RFI) on intestinal digestion capacity, particularly during immune system stimulation (ISS). Our objective was to evaluate the impact of ISS and divergent selection for RFI on apparent ileal digestibility (AID) and apparent fecal digestibility (AFD) of nutrients and intestinal nutrient active transport and barri...
Extensive efforts have been made to identify more feed-efficient dairy cows, yet it is unclear how selection for feed efficiency will influence metabolic health. The objectives of this research were to determine the relationships between residual feed intake (RFI), a measure of feed efficiency, body condition score (BCS) change, and hyperketonemia (HYK) incidence. Blood and milk samples were co...
and Implications The relationships between body condition score (BCS) observed during the first 45 days of lactation and two measures of feed efficiency, residual feed intake (RFI) and gross efficiency (GE) defined as milk energy / DMI, measured during mid-lactation were assessed in 255 first lactation Holstein cows. No significant differences in BCS at calving and at approximately 40 days in m...
Radio astronomical pulsar observations require specific instrumentation and dedicated signal processing to cope with the dispersion caused by the interstellar medium. Moreover, the quality of observations can be limited by radio frequency interferences (RFI) generated by Telecommunications activity. This paper will present the innovative pulsar instrumentation based on Graphical Processing Unit...
Characterizing and Correcting Residual RFI Signatures in Operationally Processed ALOS-PALSAR Imagery
Radio-frequency interference (RFI) has long been identified as a problem in L-band Synthetic Aperture Radar (SAR), as it is limiting the application, performance, and data quality of SAR at many areas around the globe. Several algorithms for RFI mitigation have been developed throughout the recent decades (Le, et al., 1998; Reigber and Ferro-Famil, 2005; Rosen, et al., 2008) in response to this...
An obvious issue with a low-frequency broad-band receiver is the degree to which the science data are affected by radio-frequency interference (RFI). RFI comes in two main classes: a) relatively narrow-band quasi-steady transmissions and b) broad-band transient signals. Very strong narrowband signals can result in non-linear responses which dramatically spread the signal in frequency. Transient...
Direct and maternal genetic parameters for production traits in 1,642 pigs and maternal genetic correlations among production (1,642 pigs) and feed efficiency (380 boars) traits were estimated in 7 generations of a Duroc population. Traits studied were daily gain (DG), intramuscular fat (IMF), loineye area (LEA), backfat thickness (BF), daily feed intake (FI), feed conversion ratio (FCR) and re...
This document reports on a survey of radio frequency interference (RFI) in the band 1200-1800 MHz. The survey was conducted during business hours from the roof of the Ohio State University ElectroScience Laboratory (ESL), using two antennas. One antenna was a commercially available wideband discone antenna, which is weakly directive along the horizon, and has directivity ¿ 1 toward the sky. The...
This document is in response to the OMG Real-Time technologies RFI (ORBOS/9609-02). It is intended to provide responses to Requirements, Approach, Categories, Architecture and Technology aspects for integrating real-time technologies into OMG’s CORBA. This response is based on work done in the ReTINA ACTS project (project AC048) which purpose is to develop a flexible, real-time ORB, and on the ...
