Validity and Reproducibility of a Dietary Questionnaire for Consumption Frequencies of Foods during Pregnancy in the Born in Guangzhou Cohort Study (BIGCS)

This study aimed to examine the reproducibility and validity of a new food frequency questionnaire (FFQ) used in a birth cohort study to estimate the usual consumption frequencies of foods during pregnancy. The reference measure was the average of three inconsecutive 24 h diet recalls (24 HR) administrated between two FFQs, and the reproducibility was measured by repeating the first FFQ (FFQ1) approximately eight weeks later (FFQ2).

Pressure BioSciences Announces Initial Shipments of its Enabling, Next-Generation PCT System

Pressure BioSciences, Inc. (PBIO) ("PBI" or the "Company") today announced the initial shipments of its recently released, next-generation pressure cycling technology ("PCT")-based instrument, the Barocycler 2320EXTREME (the "2320EXT"). A key component to the study's success will be the maximization of the breadth of biomolecular analytes revealed and measured, and the quality and reproducibility of the results generated using the tools chosen by ProCan for both the sample preparation and analytical portions of the study.

DARPA Cyber Grand Challenge AI Will Prevail

Next month Las Vegas will host the Final Event of the DARPA Cyber grand Challenge as an all-computer cyber-defence Capture the Flag tournament. From an initial field of over 100 applicant seven teams will compete for the $3.5 million prize pool. Reproducibility is a key aspect of a sound scientific design. While perfect system state replay is impossible without a full system event recorder, DECREE has been designed to allow high determinism and reproducibility given a record of software and inputs. This reproducibility property has been built into DECREE from kernel modifications up through the entire platform stack.

Where next for the reproducibility agenda in computational biology?

The concept of reproducibility is a foundation of the scientific method. With the arrival of fast and powerful computers over the last few decades, there has been an explosion of results based on complex computational analyses and simulations. The reproducibility of these results has been addressed mainly in terms of exact replicability or numerical equivalence, ignoring the wider issue of the reproducibility of conclusions through equivalent, extended or alternative methods.
