Data from: Paleozoic diversification of terrestrial chitin-degrading bacterial lineages

Danielle S. Gruen, Joanna M. Wolfe & Gregory P. Fournier
Background: Establishing the divergence times of groups of organisms is a major goal of evolutionary biology. This is especially challenging for microbial lineages, due to the near-absence of preserved physical evidence (diagnostic body fossils or geochemical biomarkers). Horizontal gene transfer (HGT), can serve as a temporal scaffold between microbial groups and other fossil-calibrated clades, potentially improving these estimates. Specifically, HGT to or from organisms with fossil-calibrated age estimates can propagate these constraints to additional groups...

Data from: Strength of species interactions determines biodiversity and stability in microbial communities

Christoph Ratzke, Julien Barrere & Jeff Gore
Organisms, especially microbes, tend to live in complex communities. While some of these ecosystems are very bio-diverse, others aren′t, and while some are very stable over time others undergo strong temporal fluctuations. Despite a long history of research and a plethora of data it is not fully understood what sets biodiversity and stability of ecosystems. Theory as well as experiments suggest a connection between species interaction, biodiversity, and stability of ecosystems, where an increase of...

Measurements from the Fire Influence on Regional and Global Environments Experiment (FIREX) Fire Lab Mini Chamber Experiment

Christopher Cappa, Christopher Lim, David Hagan & Jesse Kroll
All experiments were conducted during the Fire Influence on Regional to Global Environments Experiment (FIREX) lab study, which took place at the Missoula Fire Sciences Lab in Missoula, MT, USA during November, 2016. Experiments focused on refining our understanding of emissions and short timescale processing. The focus was on measuring fuels or combustion conditions that are characteristic of the western U.S. that may be under-sampled by the fire research community. Numerous types of biomass were...

Data from: Segregation and polarization in urban areas

Alfredo J. Morales, Xiaowen Dong, Yaneer Bar-Yam & Alex Pentland
Social behaviors emerge from the exchange of information among individuals—constrained by and reciprocally influencing the structure of information flows. The Internet radically transformed communication by democratizing broadcast capabilities and enabling easy and borderless formation of new acquaintances. However, actual information flows are heteroge- neous and confined to self-organized echo-chambers. Of central importance to the future of society is understanding how existing physical segregation affects online social fragmentation. Here we show that the virtual space is...

Data from: Optical and molecular signatures of dissolved organic matter reflect anthropogenic influence in a coastal river, Northeast China

Ding He, Chen He, Penghui Li, Xiaowen Zhang, Quan Shi & Yongge Sun
Sources and molecular composition of dissolved organic matter (DOM) in coastal rivers have been tightly linked with its reactivity and fate, thus influencing element and nutrient cycling. The DOM in coastal rivers is usually sourced from both terrestrial and marine inputs, with further complication by anthropogenic activities, which is less understood in coastal rivers located near populated industrial regions. In this study, DOM in a typical anthropogenically influenced coastal river, Daliao River, was analyzed for...

The MIMIC-CXR Database

Alistair E. W. Johnson, Tom Pollard, Roger Mark, Seth Berkowitz & Steven Horng
The MIMIC Chest X-ray (MIMIC-CXR) Database v1.0.0 is a large publicly available dataset of chest radiographs with structured labels. The dataset contains 371,920 images corresponding to 224,548 radiographic studies performed at the Beth Israel Deaconess Medical Center in Boston, MA. The dataset is de-identified to satisfy the US Health Insurance Portability and Accountability Act of 1996 (HIPAA) Safe Harbor requirements. Protected health information (PHI) has been removed. The dataset is intended to support a wide...

Data from: Energy landscape for the insertion of amphiphilic nanoparticles into lipid membranes: a computational study

Reid C. Van Lehn & Alfredo Alexander-Katz
Amphiphilic, monolayer-protected gold nanoparticles (NPs) have been shown to enter cells via a non-endocytic, non-disruptive pathway that could be valuable for biomedical applications. The same NPs were also found to insert into a series of model cell membranes as a precursor to cellular uptake, but the insertion mechanism remains unclear. Previous simulations have demonstrated that an amphiphilic NP can insert into a single leaflet of a planar lipid bilayer, but in this configuration all charged...

MIMIC-III Clinical Database Demo

Alistair Johnson, Tom Pollard & Roger Mark
MIMIC-III is a large, freely-available database comprising deidentified health-related data associated with over 40,000 patients who stayed in critical care units of the Beth Israel Deaconess Medical Center between 2001 and 2012 [1]. The MIMIC-III Clinical Database is available on PhysioNet (http://doi.org/10.13026/C2XW26). Though deidentified, MIMIC-III contains detailed information regarding the care of real patients, and as such requires credentialing before access. To allow researchers to ascertain whether the database is suitable for their work, we...

Data from: Deep-tissue optical imaging of near cellular-sized features

Xiangnan Dang, Neelkanth M. Bardhan, Jifa Qi, Li Gu, Ngozi A. Eze, Ching-Wei Lin, Swati Kataria, Paula T. Hammond & Angela M. Belcher
Detection of biological features at the cellular level with sufficient sensitivity in complex tissue remains a major challenge. To appreciate this challenge, this would require finding tens to hundreds of cells (a 0.1 mm tumor has ~125 cells), out of ~37 trillion cells in the human body. Near-infrared optical imaging holds promise for high-resolution, deep-tissue imaging, but is limited by autofluorescence and scattering. To date, the maximum reported depth using second-window near-infrared (NIR-II: 1000–1700 nm)...

Xenon hydrate as an analogue of methane hydrate in geologic systems out of thermodynamic equilibrium

Xiaojing Fu, William Waite, Luis Cueto-Felgueroso & Ruben Juanes
This data set contains simulation results of hydrate growth on a gas-liquid interface for both methane and xenon hydrate systems. The simulations are performed on a 1D domain of 115 micron in length and for a duration of 40 minutes. The data set contains two MATLAB data files (methane_data.mat and xenon_data.mat) and one file to help users to visualize the data (plot_data.m). In the file plot_data.m, we also use experimental data from Taylor et al....

Causes of oceanic crustal thickness oscillations along a 74-Myr Mid-Atlantic Ridge flow line

William Shinevar, Hannah Mark, Fiona Clerc, Emmanuel A. Codillo, Jianhua Gong, Jean-Arthur Olive, Stephanie Brown, Paris T. Smalls, Yang Liao, Véronique Le Roux & Mark Behn
Gravity, magnetic, and bathymetry data collected along a continuous 1400-km-long spreading-parallel flow line across the Mid-Atlantic Ridge indicate significant tectonic and magmatic fluctuations in the formation of oceanic crust over a range of timescales. The transect spans from 28 Ma on the African Plate to 74 Ma on the North American plate, crossing the Mid-Atlantic Ridge at 35.8 ºN. Gravity-derived crustal thicknesses vary from 3–9 km with a standard deviation of 1 km. Spectral analysis...

Archival data and code in support of uncertainty quantification of climate system properties using the MIT Earth System Model (MESM)

Chris Forest, Alex Libardoni, Andrei P. Sokolov & Erwan Monier
This archive provides the climate model outputs, observational data, and analysis codes that were used to quantify uncertainty in the climate system response properties of the MIT Earth System Model (MESM). Three papers (Libardoni et al. 2018a, 2018b, 2019) include results using these data and codes to provide conditional probability distributions of equilibrium climate sensitivity (ECS), the transient climate response (TCR), and the net radiative forcing by aerosols. The analysis codes are either written in...
