Mali flora images
User Collection
- Creator:
- Heath, Jeffrey G.
- Description:
- These images of plants, in nature or as fresh or dried specimens, were made in conjunction with research on languages of the Dogon and Bozo families, along with the isolated language Bangime, in Central Mali between 2006 and 2023. (See also the work "Dogon and Bangime flora terms from central Mali (2023)" in Deep Blue Data: https://doi.org/10.7302/34vf-jk03. The late Pierre Poilecot of CNRS (Montpellier, France) provided invaluable help in the early days. However, I am responsible for the determinations (including taxonomic updates), and I am not a professional botanist. The images range from poor to excellent technical quality. They may be of use for two purposes: a) acquiring a basic knowledge of the flora of the area, for newcomers; b) as vouchers for the determinations in my lexical spreadsheets on the various languages. While the main burst of taxonomic changes due to molecular studies has probably leveled off as of 2023, some revisions at all levels (family, genus, species) will occur over time. The African Flowering Plant Database at url https://africanplantdatabase.ch is especially useful for updates/synonymies at the species level, but tends to lag behind on revisions at the family level., Each "work" for flowering plants in this collection has the title "Mali flora images X" where X is the name of a botanical family. Users who enter at the collection level should search by family (from Acanthacaceae to Zypɣophyllaceae). Large families Poaceae, Malvaceae, and Fabaceae are divided into two or more works, but they will all show up in search results for the family. There is one work for non-flowering plants with title "Mali aa fern fungus lichen images"., Within each work, the individual images have file names like these: fl_Amaranthaceae_Celosia_trigyna_Beni_10_2011_fl_50035_JH.JPG fl_Lamiaceae_Hoslundia_opposita_Barato_09_2021_piripirinaw_03_fol_fr_JH.JPG fl_Zygophyllaceae_Tribulus_terrestris_Sevare_patch_50672_JH.tif fl_Fabaceae_Caesalpinioideae_mimosoid_Vachellia_(or_Acacia)_nilotica fuwON_1_Barato_09_2021_entire_JH.JPG They begin with "fl" for flora, the family, the genus, and the species epithet. For Fabaceae, the subfamily and if relevant "mimosoid" (part of subfamily Caesalpinioideae) precedes the genus. These items are separated by underlines (important to note if searching for a genus-species binomial). The remaining items were mostly for my own use. They may include a location (on which see the following paragraph), the date, a crude representation (without IPA symbols or diacritics) of a native name, a five-digit code for my use, a photo number like "2" for the same plant, "JH" to indicate that the image was taken by me or by a member of a project I directed, jpg or occasionally tif for forrmat, and an indicator of what part of the plant is shown: entire, bark, fl[ower], fol[iage], lf (leaf), fr[uit], tr[unk], br[anch], th[orn]. File names can be quite long especially for Fabaceae because of the subfamily names. In lists of files under such works, the file name may be shown in abbreviated form (with ellipsis ...) so that the genus and species terms may not be visible. The only way to find files for a particular species is by searching for that species. Alternatively, all of the files in a work can be downloaded in zip form and users can then see complete file names. The readme's for each work list the included species. , Most of the locations indicated are in the Dogon-speaking area, which includes cliffs, high plateaus, inselbergs, sandy plains, seasonal rivers, and small ponds. Dogon locations include Beni, Tupere, Ségué, Bendiely, Dianwely, Anda, Walo, and Tongo Tongo, among others. The inselbergs and adjoining plains of the montane Songhay are represented mainly by Hombori and Kikara. The Niger and Bani river zone from Mopti to Segou, a mainly Bozo-speaking area that features seasonal floodplains, is represented mainly by Djenne, Barato, and Kolongo. , and Some of these plants are featured in documentary-style videos. There are two collections of such videos from Mali in Deep Blue Data: Mali documentary videos from 2023 - https://doi.org/10.7302/4851-2c52 Central Mali documentary videos - https://doi.org/10.7302/4jg9-j095 Additional flora-related videos from Mali may be archived at a later date. Some fauna images may also be archived at a later date. The various Mali collections (flora, videos) will be paralleled in time by comparable collections for southwestern Burkina Faso, and small collections for north-central Côte d'Ivoire, all in Deep Blue Data.

Burkina Faso documentary videos
User Collection
- Creator:
- Heath, Jeffrey G.
- Description:
- This is a collection of mostly short documentary-style videos related to linguistic fieldwork in southwestern Burkina Faso. The initial batch consists of videos produced in 2023, and others will be added. Versions of some of these videos overdubbed in native languages will also be produced for local consumption in Burkina. Most of the videos document everyday practical activities; some also feature useful native plants and insects. This collection is parallel to collections of videos from neighboring Mali: see "Central Mali documentary videos" (with documentaries produced up to 2018) and "Mali documentary videos from 2023 on" for the newer ones. A small collection from north-central Côte d'Ivoire is also in the works. Within each collection, the videos are organized into "works" based on the general type of activity documented.

- Description:
- The procedure followed while creating this data is summarized in Section II of Chen, Brian, et al. "Behavioral cloning in atari games using a combined variational autoencoder and predictor model." 2021 IEEE Congress on Evolutionary Computation (CEC). IEEE, 2021. This data is not a result of a research but an intermediate product that is used in research. This dataset is generated to train a behavioral cloning framework from gameplay screen captures and keystrokes of an "expert" player. The RL agent that is trained using "RL Baselines Zoo package" acts as the "expert" player, whose decision making process we desire to learn. In addition to behavioral cloning experiments, this dataset is further used to demonstrate the efficacy of a novel incremental tensor decomposition algorithm on image-based data streams.

- 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:
- Healthy full-term infants were enrolled in a longitudinal study designed to examine the development of infant eating behavior. Infant weight and length was measured, mothers completed questionnaires regarding infant eating behaviors, and infants were weighed and length measured at ages 1, 2, 4, 6 and 10 months. Trajectories of eating behaviors were identified using latent class growth modeling and bivariate analyses examined associations of infant eating behavior trajectory membership with infant and maternal characteristics. Cross-lagged analyses examined associations between BEBQ subscales and infant weight-for-length z-score.

- Description:
- Generation of C2+ compounds using sunlight, carbon dioxide, and water provides a promising path for carbon neutrality. The exploration of a catalyst to break the bottleneck of C-C coupling, for constructing a rational artificial photosynthesis integrated device, is at the core. Herein, based on operando spectroscopy measurements, theoretical calculations, and feedstock experiments, it is discovered that gold, in conjunction with iridium, can catalyze the reduction of CO2, achieving C-C coupling by insertion of CO2 into -CH3. Owing to a combination of optoelectronic and catalytic properties, the assembly of AuIr with InGaN nanowires on silicon (AuIr@InGaN NWs/Si) enables the achievement of a C2H6 activity of 58.8 mmol‧g-1‧h-1 with a turnover number of 54,595 over 60 hours. A light-to-fuels efficiency of ~0.59% for solar fuels production from CO2 and H2O is achieved without any other energy inputs. This work provides a carbon-negative path for producing higher order C compounds.
