- Description:
- Tiranige is a Dogon language spoken in villages on the high plateau near the western edge of the Dogon (Bandiagara) plateau, and in villages at the base of the cliffs and slopes leading down from the plateau to the sandy plains. As of May 2018 I am still working on a drafted Tiranige grammar which I hope to complete in 2019. The grammar draft currently ends with six short texts transcribed from dictation. The only audio recording is therefore labeled Text 07. The speakers are Amadou Toloba and Boubacar Toloba. Most but not all of it (17.5 minutes out of about 22) has been partially transcribed. The plan is to complete the grammar and to transcribe and translate at least Text 07.

- Description:
- Najamba is spoken chiefly in villages on the edges of low cliffs flanking a long valley near Douentza in central Mali. It belongs to a cluster of languages/dialects including Kindige, spoken mostly along the main Douentza-Sevare highway, and the varieties around Borko on the (very) high plateau on the northwestern edge of the Dogon (Bandiagara) plateau. These varieties are often collectively called Bondu So, but this is an exonym. A grammar of Najamba was published electronically by Language Description Heritage Library in 2017 http://ldh.clld.org/2017/02/01/escidoc2397771/ It is backed up at Deep Blue documents. http://hdl.handle.net/2027.42/139022 One cassette was recorded (on one side only) in Kubewel village in 2004. Two cassettes were recorded in Adia village in 2005 in a single long session. These have been digitized. The inventory is: Kubewel: 2004-01 side A; Adia 2005-01 side A; 2005-01 side B; 2005-02 side A; 2005-02 side B. The 2004 tape had poor sound quality and was not transcribed. A substantial part of 2005-01 side A and 2005-02 side A was transcribed and translated in unpublished keyboarded documents in 2009 (see below). The material from 2005-01 side A was further edited and appeared as a single long text at the end of the published grammar. The unpublished documents included in this work are: transcriptions: Dogon Najamba 2005_01_A Adia text transcribed 2009; Dogon Najamba 2005_02_A Adia text transcribed 2009. translations: Dogon Najamba 2005_01_A Adia text translated 2009; Dogon Najamba 2005_02_A Adia text translated 2009

- Description:
- Yorno So is the variety of the Toro So subgroup of the Dogon language family. It is spoken in the Yendouma village cluster along the base of cliffs on the eastern side of the Dogon (Bandiagara) plateau in east-central Mali. It is not yet completely clear whether it is best described as a dialect of Toro So (which also includes Sangha So, Ibi So, and other varieties), or as a separate language. As of May 2018 my opinion is that it is a dialect. A grammar of Yorno So was published electronically at Language Description Heritage Library in 2017. http://ldh.clld.org/2017/09/01/escidoc2326768-2/ This is backed up at Deep Blue documents. http://hdl.handle.net/2027.42/139021.

- Description:
- Results of computer simulation of near Earth space is looked at in a new way to understand how energy moves around the global system. It is found that in addition to a pathway of energy from the outside into the system and back again there is an internal loop which recirculates energy. These new methods will greatly improve our understanding how the whole magnetosphere system evolves and will help address evolution of processes that have space weather impacts.

- Description:
- Rotating Magnetic Field (RMF) thrusters are a form of electrodeless plasma propulsion. This technology is a low maturity but potentially enabling candidate for high-power in-space propulsion for use with alternative propellants. The purpose of the data here, and the associated publication is to evaluate the phenomenological efficiency modes for this thruster test article to explain and understand its overall efficiency. These modes include divergence, power coupling, mass utilization, and plasma/acceleration efficiency. Additional time-resolved measurements of the internal plasma properties were performed using a triple Langmuir probe to evaluate energy loss processes within the thruster.

- Description:
- Tebul Ure is a Dogon language spoken on the heights in a horseshoe valley between Bamba and Yanda on the eastern edge of the Dogon (Bandiagara) plateau in central Mali. A grammar is drafted but incomplete as of May 2018. Texts were transcribed from dictation in 2012 in the Tebul area, and others were recorded digitally in 2015 at a nearby town on the plateau. Six of the 2015 texts have been transcribed. The texts are included at the end of the grammar. I grant permission to other linguists to transcribe, translate, or analyse any texts that remain untranscribed beginning 2022.

- Description:
- Our research focuses on providing a fully-imputed map of the worldwide total electron content with high resolution and spatial-temporal smoothness. We fill in the missing values of the original Madrigal TEC maps via estimating the latent feature of each latitude and local time along the 2-D grid and give initial guess of the missing regions based on pre-computed spherical harmonics map. The resulting TEC map has high imputation accuracy and the ease of reproducing. All data are in HDF5 format and are easy to read using the h5py package in Python. The TEC map is grouped in folders based on years and each file contains a single-day data of 5-min cadence. Each individual TEC map is of size 181*361. and WARNING: 2023-12-01 the data file for 2019-Jan-03 has badly fitted values. Please avoid using it. All other days' files are ready to use.

- Description:
- This dataset was generated for our work: "Complex motion of steerable vesicular robots filled with active colloidal rods". In this project, we used Brownian molecular dynamics simulations to study the rich dynamical behavior of rigid kinked vesicles that contain self-propelling rod-shaped particles. We identified that kinks in the vesicle membrane bias the emergent clustering and alignment of the active agents. Based on the system's geometrical and material properties, we were able to design multiple types of directed motion of the vesicle superstructure. This dataset includes simulation data for two-dimensional systems of self-propelling rod particles confined by teardrop-shaped coarse-grained vesicles. The trajectory of each simulation is saved in a GSD format file with parameter metadata in a JSON file. Due to the large number of replicas of each pair of parameters, simulation data were grouped into 5 different folders. Collective quantitative analysis for simulated trajectories was performed with Jupyter Notebook. and Workspaces_simulations.zip contains all the workspaces of simulations Each folder has subfolders called 'dimer' and 'trimer' depending on the length of the propelling rod particles used in the simulation. (Except for the folder 'number-density_16' which has only 'dimer') In the subfolders, we include the Python scripts used in this work for simulating and trajectory analysis for individual trajectory data. The parameter space of each folder is noted in init.py. Analysis_jupyter_notebooks.zip includes Jupyter notebooks that can reproduce the collective analysis done for this work.

- Description:
- Amyloid nanofibers are abundant in microorganisms and are integral components of many biofilms, serving various purposes, from virulent to structural. Nonetheless, the precise characterization of bacterial amyloid nanofibers has been elusive, with incomplete and contradicting results. The present work focuses on the molecular details and characteristics of PSMa1-derived functional amyloids present in Staphylococcus aureus biofilms, using a combination of computational and experimental techniques, to develop a model that can aid the design of compounds to control amyloid formation. Results from molecular dynamics simulations, guided and supported by spectroscopy and microscopy, show that PSMa1 amyloid nanofibers present a helical structure formed by two protofilaments, have an average diameter of about 12 nm, and adopt a left-handed helicity with a periodicity of approximately 72 nm. The chirality of the self-assembled nanofibers, an intrinsic geometric property of its constituent peptides, is central to determining the fibers' lateral growth.

- Description:
- A growing body of work has linked key biological activities to the mechanical properties of cellular membranes, and as a means of identification. Here, we present a computational approach to simulate and compare the vibrational spectra in the low-THz region for mammalian and bacterial membranes, investigating the effect of membrane asymmetry and composition, as well as the conserved frequencies of a specific cell. We find that asymmetry does not impact the vibrational spectra, and the impact of sterols depends on the mobility of the components of the membrane. We demonstrate that vibrational spectra can be used to distinguish between membranes and, therefore, could be used in identification of different organisms. The method presented, here, can be immediately extended to other biological structures (e.g., amyloid fibers, polysaccharides, and protein-ligand structures) in order to fingerprint and understand vibrations of numerous biologically-relevant nanoscale structures.

- Description:
- In this study, we experimentally tested for the effects of four simulated predator cues on defensive displays in two species of South American calico snakes (genus Oxyrhopus). We found that juvenile snakes were both more likely to respond and to respond more strongly than adults and that displays were most common in response to tactile stimuli than to other treatments. However, we also found broad similarity across both simulated predator treatments and species in the components used in each snake’s defensive display, suggesting a high degree of stereotyping. This research suggests an important role for both ontogeny and intensity of predation risk in structuring variation in defensive behavior in Neotropical snakes and emphasizes the foundational importance of context dependence in conceptual frameworks for understanding predator-prey interactions. and *On January 4, 2024, “Supplementary_material.pdf” was replaced with an updated version that has slightly different versions of Figures S4 and S8 after an error in code was corrected. Within “HeatmapFigures.zip,” two code files, “IndividualHeatmaps_matrices.R” and “FigureS4_S8_averagedHeatmaps.R” were updated to correct the code error. Three additional files were added to both the “figures” and “matrices” folders within the subfolder “heatmaps.” These files represent the correlation matrices, by body part, and graphical representation of the matrices for one experimental trial that had previously been excluded due to the code error.

A cluster randomized controlled trial was conducted in 14 facilities in four districts of the Eastern Region of Ghana. Health facilities were randomized using a matched pairs design; each pair was similar in the number of deliveries and average gestational age of the women at enrollment in antenatal care. The locations of the facilities were far enough apart to avoid cross-group contamination. In each pair of facilities, one was randomly assigned to the intervention (G-ANC) and the other to the control (I-ANC). Recruitment began July 2019 and ended when enrollment targets were met. Data collection ended July 2023 when data collection was complete.

- Description:
- Image Pre-Processing To allow reliable detection and comparison of changes between several individuals or within the same individual at different time points, before extracting the quantitative bone texture/morphometry features, all hr-CBCT scans were pre-processed using validated protocols. Extraction of Trabecular Bone Texture-based and Morphometry Imaging Features Using the “crop-volume” tool in 3D Slicer, a rectangular shaped volume of interest (VOI) was cropped from the trabecular bone in the mandibular condyles and the articular fossa. Then, using the average minimum and maximum intensity values of all VOIs, we standardized the grey level intensities of the VOIs to eliminate inaccuracies of textural features calculation and possible dependency on the global characteristics of the images. Lastly, imaging markers were extracted from the standardized VOIs using “BoneTexture” module in 3D-slicer. Measurement of the 3D Articular Joint Space To assess the progression/improvement of osteoarthritic changes in the affected individuals, we measured the 3D superior joint space. We pre-labelled two landmarks in the sagittal view of the oriented CBCT scans: on the most superior point of the condyle and on the opposing surface of the articular fossa. To avoid biasing the landmarks’ placements, pre-labelling was performed simultaneously on T1 and T2 scans, using two independent windows in ITK-SNAP. After the volumetric reconstruction of the identified landmarks, linear measurements were obtained in millimeters using the Q3DC tool in 3D Slicer. Three-dimensional Shape Analyses and Quantification of Remodeling in the Condyles SPHARM-PDM software was used to compute the correspondence across 4002 surface points among all condyles. The output point-based models displayed color-coded maps that enabled visual evaluation of consistent parametrization of all condyles. An average condyle shape for the TMJ OA and control groups was calculated through propagation of original surface point correspondences across all stages of deformations and averaging the condyle surface meshes. For visualization of the 3D qualitative changes of the average models within the same group at different time points or among different groups, semi-transparent overlays were created using 3D Slicer software. The vector differences were presented on the condyle surfaces, scaled according to the magnitude of difference, and pointing towards the direction of bone change. For quantification of remodeling in the condyles, calculation of signed distances across condyles surface meshes reflected the quantitative bone changes in the TMJ OA and control samples. To quantify regional bone changes across the lateral and anterior surfaces of the condyles, we used the Pick ‘n Paint tool in 3D Slicer to propagate regional surface points to the corresponding regions of shapes across all subjects and time points.

- Description:
- We developed a new model framework based on WRF-Chem, simulating primary biological aerosol particle emissions and their interaction with clouds. We have designed different sensitivity tests to evaluate the effects of pollen and sub-pollen particles (SPPs), respectively. Our results show that SPPs have a larger effect on cloud microphysics and precipitation than whole pollen grains.
