WAY-EEG-GAL is a dataset designed to allow critical tests of techniques to decode sensation, intention, and action from scalp EEG recordings in humans who perform a grasp-and-lift task. Twelve participants performed lifting series in which the object's weight (165, 330, or 660 g), surface friction (sandpaper, suede, or silk surface), or both, were changed unpredictably between trials, thus enfo...

PURPOSE To present a new technique to ensure the correct positioning of ruthenium plaques in episcleral brachytherapy. MATERIALS AND METHODS An acrylic dummy plaque is made opaque by sanding both sides with sandpaper, and its edge is covered by a black marking tape. This modified plaque is temporarily sutured to the sclera overlying the choroidal tumour site. The tip of an endoillumination pr...

Reconstructing Geometry from Its Latent Structures Geoffrey Oxholm Ko Nishino, Ph.D. Our world is full of objects with complex shapes and structures. Through extensive experience, humans quickly develop an intuition about how objects are shaped, and what their material properties are simply by analyzing their appearance. We engage this intuitive understanding of geometry in nearly everything we...

We study the correlation of wetting properties and corrosion rates on hydrophobized cast iron. Samples of different surface roughnesses (abraded by sandpaper) are studied without coating and with two types of hydrophobic coatings (stearic acid and a liquid repelling spray). The contact angles and contact angle hysteresis are measured using a goniometer while corrosion rates are measured by a po...

We report on the enhancement of photoluminescence PL from polymer thin films by nanotexturing their surfaces using nanoporous anodic alumina oxide templates. Chromophore-embedded polystyrene films with nanostructured surfaces are prepared by imprinting 200 nm diameter nanopillars with various heights, and their PL output and angular emission are observed. The PL output increases and the angular...

The use of argon laser (488 nm) has been suggested as a new alternative for polymerizing adhesive materials. This study aimed to evaluate the tensile bond strength of a microfilled composite (A110, 3M) inserted by incremental technique (3 increments of 1 mm) and by single increment (3 mm) polymerized by argon laser for 10, 20 and 30 seconds and halogen light for 40 seconds. Eighty (8 groups of ...

BACKGROUND AND OBJECTIVES Various physical methods, such as microneedling, laser ablation, sonophoresis, and sandpaper, have been widely studied to enhance the transdermal delivery of tissue optical clearing (TOC) agents. A previous study demonstrated that the microneedling method could effectively enhance the permeability of a TOC agent through the skin barrier. STUDY DESIGN/MATERIALS AND ME...

Background: A bonded fixed retainer is used to stabilize the alignment of teeth. Different composites have been introduced for this purpose. This study aimed investigate wear resistance flowable nanocomposite in comparison with microhybrid composite an vitro situation. Materials and Methods: In study, 46 disk‑shaped specimens were divided into two groups: Filtek Ultimate Z250 composite. The sam...

The spatio-temporal characteristics of turbulent separations beneath semi-submerged bluff bodies with different undersurface roughness conditions are studied using a time-resolved particle image velocimetry. Reynolds number based on the free-stream velocity and submergence depth was fixed to 14 400. Three – smooth, sandpaper cube were examined. results showed that wall reduces mean reattachment...

Here, a fluorine-free robust superhydrophobic coating was fabricated on the Al alloy substrate by simple and low-cost approach. Embed modified TiO2 nanoparticles onto semi-cured epoxy resin adhesive layer prominently reduces content of low-energy materials (stearic acid) coating. This prepared with hierarchical structures, re-entrant structures low surface energy shows superhydrophobic. The exc...
