Observation of a regular structure formation on the surface of vibrated ball beds started from random lose packing

<p>Near 4,000 2-mm diameter plastic balls were poured 88 times into plexiglass cylinder of internal diameter 26 mm. Then, such initially random loose-packing systems/beds were vibrated vertically with 100 Hz frequency using the vibration table Vibrax (Renfert GmbH, Germany) working in sinusoidal mode until a regular structure was observed on the cylinder surface. The power levels of the vibrations in the recorded ordering of balls were selected to represent all four levels (1, 2, 3 or 4) of vibrations available in the table, where number 1 means the weakest vibration and 4 means the strongest one.</p> <p>Locations of the balls on all sides of a vibrated cylindrical bed were simultaneously recorded on one video frame thanks to the use of two perpendicular mirrors, which enables observation of four images: one of the real cylinder and three of its mirror reflections. View of the table with the attached cylinder containing balls and two mirrors is presented in Fig. 1, while an explanation of the scene, as seen by the recording camera, is given in the scheme in Fig. 2. Video names were given in a standard form explained in the README.txt file.</p>

Comparing the integration of bone cells on an even and a nano structured surface

<p>Bone cells develop better on a nano structured surface.</p> <p>Successful cellular integration is extremely important to the long-term viability of dental implants. The sooner cells can attach and surround the implant, the faster the patient recovers, and the lower the incidence of infection and site contamination. The specific biological response of the surrounding tissues depends enormously on the surface characteristics of the particular biomaterial. Moreover mouth infections are currently regarded as the main reason why dental implants fail. Therefore, antibacterial properties are another requirement for preventing potential bacterial infection.</p> <p>The multi-beam optical module developed within LASER4SURF, will be able to obtain functionalized metallic surfaces with textures around 1μm or less, enabling the required tolerances to reach the best cell adhesion and antibacterial properties. Thus, it will lead to extended implant life, reduced rejection and improved overall quality of life for patients.</p>

Computed surface and chemical potentials, expansion coefficients, structures, models and results for the PMFPredictor Toolkit

<p>The PMFPredictor toolkit enables the prediction of the potentials of mean force describing the interaction between a surface and a small molecule in aqueous solution, which would otherwise be obtained from lengthy metadynamics simulations. This repository contains files to enable the operation of the toolkit, with source code available at https://github.com/ijrouse/PMFPredictor-Toolkit and corresponding to release v0.5-alpha.</p> <p>In PMFPredictor-Repository.zip we provide supplementary data necessary for the operation of the PMFPredictor Toolkit including:</p> <ul> <li>Structures of surfaces ("Structures/Surfaces") and chemicals ("Structures/Chemicals") in a united tabulated (.csv) format, listing x/y/z co-ordinates, atom IDs, mass (in amu), charge (in elementary units), Lennard Jones 6-12 parameters: sigma (in nm) and epsilon (in kJ/mol).</li> <li>Interaction potentials of surfaces ("SurfacePotentials") and chemicals ("ChemicalPotentials") with probe atoms and molecules in tabulated format with distances relative to reference points in nm and energies in kJ/mol. Also included in these folders are the potentials with the molecular probes in individual files.</li> <li>Hypergeometric expansion coefficients of the interaction potentials ("Datasets/SurfacePotentialCoefficientsNoise-1-oct12.csv" and "Datasets/ChemicalPotentialCoefficients-oct10.csv") in tabulated form, corresponding to potentials with units of nm for distance and kJ/mol for energy. Descriptions of the headers are provided in DatasetHeaderDescription.txt, included in the archive.</li> <li>Trained TensorFlow models for the prediction of potentials of mean force from HG interaction coefficients, suitable for loading via the Keras backend.</li> <li>PMFs generated for a range of surfaces and chemicals as output from the trained model, in both text format and figures showing comparisons to training PMFs where available. PMFs are supplied as tabulated data with comma separated values of distance in nm and interaction energies in kJ/mol.</li> <li>Adsorption energies in kJ/mol evaluated at T=300K extracted from all PMFs and compared to the values obtained from known PMFs where available.</li> </ul> <p>The surface_pmfpredictor.zip  archive contains PMFs selected for the operation of the UnitedAtom software package for the calculation of protein-nanoparticle interactions. This data is included in the main repository file and provided separately to avoid the download of unnecessary data if only the final PMFs are required. As with the main set, these are provided in tabulated form with distance [nm], energy [kJ/mol] pairs. This repository also contains the sets of figures illustrating these PMFs for each surface. Both archives contain further information on the contents, including descriptions of the surfaces and chemicals for which PMFs are computed. We also supply the training data used to build the model in a separate archive, PMFPredictor-TrainingData.zip, along with a text file containing descriptions of all headers in this file. This training data is quite large when uncompressed, c.a. 7 Gb, hence its exclusion from the main archive.</p> <p>If you use results from this repository please cite the following paper in addition to the repository itself:</p> <p>I. Rouse, V. Lobaskin, Machine-learning based prediction of small molecule -- surface interaction potentials,      arXiv:2211.07999<br> https://arxiv.org/abs/2211.07999</p>
