Quantifying and understanding well-to-well contamination in microbiome research [article]

Jeremiah J Minich, Jon Sanders, Amnon Amir, Greg Humphrey, Jack A Gilbert, Rob Knight
2019 bioRxiv   pre-print
Using unique bacteria each assigned a particular well in a plate, we assess the frequency at which sequences from each source appears in other wells.  ...  Our work emphasizes that sample contamination is a combination of crosstalk from nearby wells and background contaminants.  ...  surrounding the source well, 173 suggesting a physical mechanism for well-to-well contamination ( Figure 2 ).  ...

Quantifying and Understanding Well-to-Well Contamination in Microbiome Research

Jeremiah J. Minich, Jon G. Sanders, Amnon Amir, Greg Humphrey, Jack A. Gilbert, Rob Knight, Nicola Segata
2019 mSystems  
Using unique bacteria, each assigned a particular well in a plate, we assess the frequency at which sequences from each source appear in other wells.  ...  Well-to-well contamination occurred primarily during DNA extraction and, to a lesser extent, in library preparation, while barcode leakage was negligible.  ...  the source well, suggesting a physical mechanism for well-to-well contamination (Fig. 2) .  ...

Matching: A Well-Solved Class of Integer Linear Programs [chapter]

Jack Edmonds, Ellis L. Johnson
2003 Lecture Notes in Computer Science  
A main purpose of this work is to give a good algorithm for a certain welldescribed class of integer linear programming problems, called matching problems (or the matching problem).  ...  In the process, we derive a description of a system of linear inequalities whose polyhedron is the convex hull of the admissible solution vectors to the given matching problem.  ...  By contrast with general integer linear programming, the matching problem is well-solved. (7) Theorem.  ...

Global well-posedness and multi-tone solutions of a class of nonlinear nonlocal cochlear models in hearing [article]

Jack Xin
2003 arXiv   pre-print
The global well-posedness in time follows from energy estimates. Uniform bounds of solutions hold in case of bounded nonlinear damping.  ...  We study a class of nonlinear nonlocal cochlear models of the transmission line type, describing the motion of basilar membrane (BM) in the cochlea.  ...  Let us show that M is a well-defined bounded mapping from B 1 to itself.  ...

The dangers of non-powder firearms

Brandi A. Chrismas, Jack Powles
2019 Journal of community safety & well-being  
Non-powder weapons have become a persistent threat in today's society.  ...  They are a particular challenge for law enforcement, who cannot be expected to distinguish fake firearms from real ones under stress.  ...  In this case as well, the weapon was later discovered to be a non-powder firearm, a BB gun (Ontario Human Rights Commission, 2018).  ...

Effects of Fire Severity and Woody Debris on Tree Regeneration for Exploratory Well Pads in Jack Pine (Pinus banksiana) Forests

Angelo T. Filicetti, Ryan A. LaPointe, Scott E. Nielsen
2021 Forests  
In this study, we compared the effects of wildfire and local variation in the amount of residual woody debris on natural regeneration in jack pine on exploratory well pads in Alberta's boreal forest.  ...  Our results demonstrate that wildfires can stimulate natural recovery of fire-adapted species, such as jack pine, on disturbances as large as exploratory well pads (500–1330 m2) and that the type and amount  ...  Nevertheless, other footprints, such as exploratory well pads (20-40 m) , are often larger and thus may have less access to jack pine seeds following a fire.  ...
