FIG. 2 in Finite element analysis of the proximal phalanx of the thumb in Hominoidea during simulated stone tool use
FIG. 2. — Free-body diagram of the phalanx in the different scenarios. This figure depicts the boundary conditions, areas of insertion of muscles, and direction of forces. For all loading configurations, joint reaction forces resulted from the rigid boundary constraints that were fixed at the distal joint in X, Y and Z-axes (light blue area), and at the proximal joint in the X-axis (dark blue area). The hammer reaction force (HRF) was applied to the entire palmar surface of the bone. 3.29 N for the HRF was simulated for Sc 1 and 3, and 7.65 N for Sc 2 and 4. Phalanges are shown in palmar (right) and radial (left) views.
FIG. 5 in Finite element analysis of the proximal phalanx of the thumb in Hominoidea during simulated stone tool use
FIG. 5. — Box-plots of von Mises stress (MPa) distribution for all species under different scenarios, until Q95 (Sc 1 in grey, Sc 2 in yellow, Sc 3 in green and Sc 4 in red). The first row shows stress distribution of the models using the extant human as a reference to scale muscular forces in all other specimens, whereas the second one shows the results when the chimpanzee is used as a reference. Species are ordered from higher to lower peak stresses.
FIG. 1 in Finite element analysis of the proximal phalanx of the thumb in Hominoidea during simulated stone tool use
FIG. 1. — Biomechanical model of hammerstone use: B, corresponds to a zoom in palmar view of the area of interest during A, the grip of a human individual (based on Marzke et al. 1998). B, shows the angles of the muscular forces acting on the PP1. HRF is in 90° relative to the horizontal line for scenarios 1 and 2 and in 45° for scenarios 2 and 4. This force was applied on the entire palmar surface of the PP1 except in the joint areas and is represented with a hatched rectangle. Angles of the muscle forces are shown relative to the horizontal line. Abbreviations: FAP, Adductor Pollicis Force; FAPB, Abductor Pollicis Brevis Force; FFPB, Flexor Pollicis Brevis Force; EPB, direction force was applied in 16.7° and is not showed here as it attached on the dorsal surface of the PP1. Grey rectangles represent the origin areas of the muscles.
FIG. 3 in Finite element analysis of the proximal phalanx of the thumb in Hominoidea during simulated stone tool use
FIG. 3. — Von Mises stress maps for all analyzed species under different loading scenarios using the extant human as reference to scale the simulated muscular forces in all other specimens. Species are ordered from higher to lower peak stresses values. Phalanges are shown at the same length. MPa bar is set at 12 MPa.
FIG. 4 in Finite element analysis of the proximal phalanx of the thumb in Hominoidea during simulated stone tool use
FIG. 4. — Von Mises stress maps for all analyzed species under different loading scenarios using the chimpanzee as reference to scale the simulated muscular forces in all other specimens. Species are ordered from higher to lower peak stresses values. Images are not scaled. MPa is set at 25 MPa.

Elements of Style in Reproducible Workflow Creation and Analysis: An INCLUDE Training Event
<p><a href="https://github.com/NIH-NICHD/Elements-of-Style-Workflow-Creation-Maintenance/blob/main/README.md">Elements of Style Workflow Creation and Maintenance</a>: An INCLUDE Training Event</p> <p>The <a href="https://includedcc.org/">INCLUDE Data Hub</a> is a new resource that securely hosts human clinical, genomic, transcriptomic, proteomic, and other data providing a wealth of opportunities to study conditions that affect individuals with Down syndrome. Today, the approach to answering new scientific questions with these data often uses cloud-based methods accessible through web browsers.</p> <p>During a three-hour virtual training, users learn the know-how to ask scientific questions with these data using cloud platforms and workflows. Users will learn how to build and share processes that assure reproducibility, repurposablility regardless of the computational environment. While many things are possible, the user will be oriented to approaching their work in a modular, testable fashion. </p>
IODP Expedition 372A ICP-AES elemental analysis (interstitial water)
<p>Elemental concentration in interstitial water samples was measured by inductively coupled plasma - atomic emission spectroscopy (ICP-AES). Data are presented by element-wavelength pair (e.g., more than one calcium line may be reported). Elemental lines for which data do not exist for a particular expedition will not appear.</p>
IODP Expedition 372A Elemental analysis (CHNS)
<p>Fundamental elemental component (total carbon, hydrogen, nitrogen, and sulfur) fluctuations help define the origin, depositional environment, and diagenetic alteration of source materials. To determine C, H, N, and S, solid samples are reacted with a catalyst, separated by chromatography, and detected by thermal conductivity on a FlashEA 1112 CHNS elemental analyzer. Organic carbon can be directly measured on the elemental analyzer by acidification of the sample to drive off carbonate as carbon dioxide before analyzing. Total organic carbon on this report is measured rather than calculated.</p>

[Demo Input Data] for SCAFE: a software suite for analysis of transcribed cis-regulatory elements in single cells
<p>This archive (input.tar.gz) contains the demo data for SCAFE v1.0.0 (on <a href="https://doi.org/10.5281/zenodo.7023163">Zenodo</a> or <a href="https://github.com/chung-lab/SCAFE/releases/tag/v1.0.0">Github</a>)</p> <p><em>SCAFE</em> (Single Cell Analysis of Five-prime Ends) provides an end-to-end solution for processing of single cell 5’end RNA-seq data. It takes a read alignment file (*.bam) from single-cell RNA-5’end-sequencing (e.g. 10xGenomics Chromimum®), precisely maps the cDNA 5'ends (i.e. transcription start sites, TSS), filters for the artefacts and identifies genuine TSS clusters using logistic regression. Based on the TSS clusters, it defines transcribed cis-regulatory elements (tCRE) and annotated them to gene models. It then counts the UMI in tCRE in single cells and returns a tCRE UMI/cellbarcode matrix ready for downstream analyses, e.g. cell-type clustering, linking promoters to enhancers by co-activity <em>etc</em>.</p> <p>For details on installation, usage and test run on demo data, visit <a href="https://github.com/chung-lab/SCAFE">https://github.com/chung-lab/SCAFE</a></p>
