Learning generative models for protein fold families.
Sivaraman Balakrishnan,Hetunandan Kamisetty,Jaime G. Carbonell,Su-In Lee,Christopher J. Langmead +4 more
TL;DR: A new approach to learning statistical models from multiple sequence alignments (MSA) of proteins, called GREMLIN (Generative REgularized ModeLs of proteINs), learns an undirected probabilistic graphical model of the amino acid composition within the MSA, which encodes both the position‐specific conservation statistics and the correlated mutation statistics between sequential and long‐range pairs of residues.
Journal ArticleDOI
Comparison of existing clinical scoring systems to predict persistent organ failure in patients with acute pancreatitis.
Rawad Mounzer,Christopher J. Langmead,Bechien U. Wu,Anna C. Evans,Faraz Bishehsari,Venkata Muddana,Vikesh K. Singh,Adam Slivka,David C. Whitcomb,Dhiraj Yadav,Peter A. Banks,Georgios I. Papachristou,Georgios I. Papachristou +12 more
TL;DR: The existing scoring systems seem to have reached their maximal efficacy in predicting persistent organ failure in acute pancreatitis, and 12 predictive rules that combined these scores to optimize predictive accuracy are developed.
Book ChapterDOI
A Bayesian Approach to Model Checking Biological Systems
Sumit Kumar Jha,Edmund M. Clarke,Christopher J. Langmead,Axel Legay,André Platzer,Paolo Zuliani +5 more
TL;DR: This work presents the first algorithm for performing statistical Model Checking using Bayesian Sequential Hypothesis Testing, and shows that this Bayesian approach outperforms current statistical Model checking techniques, which rely on tests from Classical statistics, by requiring fewer system simulations.
Journal ArticleDOI
Serum biomarker panels for the detection of pancreatic cancer.
Randall E. Brand,Brian M. Nolen,Herbert J. Zeh,Peter J. Allen,Peter J. Allen,Mohamad A. Eloubeidi,Michael J. Goldberg,Eric Elton,Juan Pablo Arnoletti,John D. Christein,Selwyn M. Vickers,Christopher J. Langmead,Douglas Landsittel,David C. Whitcomb,William E. Grizzle,Anna Lokshin +15 more
TL;DR: The PDAC-specific biomarker panels identified in this investigation warrant additional clinical validation to determine their role in screening targeted high-risk populations.
Book ChapterDOI
Statistical Model Checking in BioLab: Applications to the Automated Analysis of T-Cell Receptor Signaling Pathway
Edmund M. Clarke,James R. Faeder,Christopher J. Langmead,Leonard A. Harris,Sumit Kumar Jha,Axel Legay +5 more
TL;DR: An algorithm, called BioLab, for verifying temporal properties of rule-based models of cellular signalling networks, encoded in the BioNetGen language, and properties are expressed as formulae in probabilistic bounded linear temporal logic.
