Liver proteome response to torpor in a basoendothermic mammal, Tenrec ecaudatus, provides insights into the evolution of homeothermy

October 6, 2021
Author(s)
Jane Khudyakov, Michael Treat, Mikayla Shanafelt, Jared Deyarmin, Ben Neely, Frank van Breukelen
Many mammals use adaptive heterothermy (e.g., torpor, hibernation) to reduce metabolic demands of maintaining high body temperature (Tb). Torpor is typically characterized by coordinated declines in Tb and metabolic rate (MR) followed by active rewarming

Fast and accurate prediction of hurricane evolution from genesis onwards is needed to reduce loss of life and enhance community resilience. In this work, a novel model development methodology for predicting storm trajectory is proposed based on two classes

Evaluation of existing infiltration models used in building energy simulation

September 1, 2021
Author(s)
Yeonjin Bae, Jaewan Joe, Seungjae Lee, Piljae Im, Lisa Ng
Infiltration modeling is one of the major sources of uncertainty in building energy simulation. Although many infiltration models exist, their structures and assumptions vary, and many of them are inaccurate for commercial buildings. The use of these

Naturally occurring organobromine compounds (OBCs) including polybrominated dibenzo-p-dioxins in the marine sponge Hyrtios proteus from The Bahamas

Qiong Wu, Natalie Eisenhardt, Stephanie Shaw, Joseph Pawlik, John Kucklick, Walter Vetter
Halogenated natural products (HNPs) were identified from organic extracts of the marine sponge Hyrtios proteus from The Bahamas (Caribbean, FAO fishing area 31) using gas chromatography with electron capture negative ion mass spectrometry (GC/ECNI-MS) and

Quantifying Machining Process Inventories In Detailed Design

August 24, 2021
Author(s)
William Z. Bernstein, Till Boettjer, Deverajan Ramanujan
This paper quantifies machining process inventories based on commonly used techniques in various stages of the detailed design process. We investigate variabilities in process inventories between these techniques and their relation to manufacturing process

Xiaoyu (Sara) Yang, Pedatsur Neta, Yuri Mirokhin, Dmitrii V. Tchekhovskoi, Concepcion Remoroza, Meghan Burke Harris, Yuxue Liang, Sanford Markey, Stephen E. Stein
Annotating product ion peaks in tandem mass spectra is essential for evaluating spectral quality and validating peptide identification. This task is more complex for glycopeptides and is crucial for the confident determination of glycosylation sites in

Microplastic Spectral Classification Needs an Open Source Community: Open Specy to the Rescue!

May 19, 2021
Author(s)
Win Cowger, Gray Andrew, Chelsea Rochman, Sebastian Primpke, Jennifer Lynch, Hannah Hapich, Hannah De Frond, Keenan Munno
Microplastic pollution research has suffered from inadequate data and tools for spectral (Raman and infrared) classification. Spectral matching tools often are not accurate for microplastics identification and are cost-prohibitive. Lack of accuracy stems
