Mercury Transiting the Sun

The pharmaceutical industry is on the brink of entering into the digital age, yet still suffers from fundamental misconceptions and outdated IT systems that inhibit its progress. Four key criteria are identified that have enabled labs to reach the post-modern stage, which are insights generation through advanced analytics, automatic communication through machine to machine interfaces, removal of boundaries for an open lab, and novel means of ensuring trust through automatic submissions. Further progress in these four areas will enable the pharmaceutical laboratory to enter the digital age. Unfortunately, historical roadblocks in the form of an application-centric mindset have so far stifled progress. However, initiatives that supported other industries on their path into the digital age are introduced and evidences for the benefits of the digital age are provided. These span from advanced analytics, data-centric architecture, metadata supported communication, knowledge assisted submissions, to digital maturity models. It is concluded that executives and lab staff within Pharma needs a transition to a data-centric world view to reap all the benefits of the digital age for faster, better, and cheaper drug development.

The prediction of amino acid contacts from protein sequence is an important problem, as protein contacts are a vital step towards the prediction of folded protein structures. We propose that a powerful concept from deep learning, called ensembling, can increase the accuracy of protein contact predictions by combining the outputs of different neural network models. We show that ensembling the predictions made by different groups at the recent Critical Assessment of Protein Structure Prediction (CASP13) outperforms all individual groups. Further, we show that contacts derived from the distance predictions of three additional deep neural networks—AlphaFold, trRosetta, and ProSPr—can be substantially improved by ensembling all three networks. We also show that ensembling these recent deep neural networks with the best CASP13 group creates a superior contact prediction tool. Finally, we demonstrate that two ensembled networks can successfully differentiate between the folds of two highly homologous sequences. In order to build further on these findings, we propose the creation of a better protein contact benchmark set and additional open-source contact prediction methods.

Skewness values for the pressure time derivative are greater at ground-based measurements near a tactical aircraft than they are at nearby off-ground locations. A possible explanation for this phenomenon is the occurrence of nonlinear, irregular shock reflections at the ground. Propagation angle, source location, and corresponding angle of incidence relative to the ground are estimated using a two-point cross correlation of windowed shock events. Nonlinear reflections are likely to occur based on the combination of angles of incidence and measured shock strengths and cause a pressure increase at the shock that is greater than twice the free-field pressure. The associated pressure increase at the shocks appears to enhance shock-related metrics at the ground compared to off-ground locations.
