For most types of data, information will be collected using automated (tablet-based) data entry with range checks and consistency checks incorporated into the data entry software. One exception is the dietary intake data, which will be recorded first on paper forms for preliminary review before entering the consolidated food intake data into the database.
Push Elected Officials to Pass Farm Bill [Opinion]

Oct 9, 2024 | lancasterfarming.com | Kenneth Brown

Editor:Time is getting away from us. The Farm Bill deadline has been missed again after a one year extension. Where do we go from here? This failure on the part of Congress affects everyone, especially recipients of the food program SNAP, for people who need help with basic food acquisition. This program accounts for more than 90% of the overall budget for the Farm Bill. Failure to pass the Farm Bill also throws a lot of chaos and concern into the lives of the people who produce the foods.
Concatenated Steane code with single-flag syndrome checks

A fault-tolerant error correction (FTEC) protocol with a high error suppression rate and low overhead is very desirable for the near-term implementation of quantum computers. In this work, we develop a distance-preserving flag FTEC protocol for the concatenated Steane code, which requires only two ancilla qubits per generator and can be implemented on a planar layout. We generalize the weight-parity error correction (WPEC) technique from Tansuwannont and Leung [Phys. Rev.
Ensure Ammonia for Agriculture [Opinion]

Editor:Ammonia is a combination of two elements tightly bound together, hydrogen, H2, and nitrogen, N2. Plants obtain a usable form of nitrogen either by microbial fermentation in the soil or in amendments (fertilizers). Hydrogen is reacted with nitrogen to produce ammonia, NH3, which may be used alone or modified to create other fertilizers, such as ammonium nitrate.

Popular Summary Flag fault-tolerant quantum error correction (FTQEC) is a method to suppress error rate in quantum computation that uses a small number of ancilla qubits to detect faults in the error-correction protocol. One way to guarantee the number of correctable faults is using a lookup table decoder, but building it requires exhaustive search and may not scale well with the code size.
