This study investigated the impact of different light curing units (LCUs) for the polymerization of adhesive system visio.link (VL) on the tensile bond strength (TBS) of different PEEK compositions. For TBS measurements, 216 PEEK specimens with varying amounts of TiO₂ (PEEK/0%, PEEK/20%, PEEK/>30%) were embedded, polished, air abraded (Al₂O₃, 50 µm, 0.4 MPa), conditioned using VL, and polymeriz...

In the present study, we perform molecular dynamic simulations to investigate the compression response and atomistic deformation mechanisms of twinned nanospheres. The relationship between load and compression depth is calculated for various twin spacing and loading directions. Then, the overall elastic properties and the underlying plastic deformation mechanisms are illuminated. Twin boundarie...

Objectives: The aim of this study was to compare the microtensile bond strengths (µ TBS) of three core materials with one lithium disilicate reinforced ceramic using two resin cements. Methods: Three core materials (Nulite F® (Biodental Technologies), Filtek Z250® (3M-ESPE), Prettau-Anterior® (Zirkonzhan, Germany)) were prepared as blocks (10×10×4 mm3) according...

This paper formalizes the concept of threshold blind signatures (TBS) that bridges together properties of the two well-known signature flavors, blind signatures and threshold signatures. Using TBS users can obtain signatures through interaction with t-out-of-n signers without disclosing the corresponding message to any of them. Our construction is the first TBS scheme that achieves security in ...

BACKGROUND Traditional Botanical Supplement-101 (TBS-101) is a newly developed proprietary botanical agent containing seven standardized botanical extracts, including: Panax ginseng, cranberry, green tea, grape skin, grape seed, Ganoderma lucidum and chamomile. Each of the components has been consumed either in the regular diet or as natural supplement. When used as a single agent, each of thes...

The fasciolicides tribromsalan (TBS), oxyclozanide (OCZ) and bromofenofos (BFF) were orally administered to three lactating cows. The concentrations of TBS, OCZ and the BFF metabolite dephosphate bromofenofos (DBFF) in plasma, and the excretion of these compounds in milk were determined by high-performance liquid chromatography. In plasma, the concentrations of TBS, OCZ and DBFF reached maximum...

To the Editor: Repetitive transcranial magnetic stimulation (rTMS) is a potential therapy for major depressive disorder and obsessive-compulsive disorder that acts by modulating cortical activities. 3 have developed a novel paradigm of theta-burst stimulation (TBS)—low-intensity bursts of rTMS at 50 Hz—as a safer, more controllable, more consistent, and longer-lasting rTMS. The continuous TBS (...

Modulatory effects of repetitive transcranial magnetic stimulation (TMS) depend on the activity of the stimulated cortical area before, during, and even after application. In the present study, we investigated the effects of theta burst stimulation (TBS) on visual cortex excitability using phosphene threshold (PTs). In a between-group design either continuous or intermittent TBS was applied wit...

In the present study, a coarse grained AZ31 plate was refined by twin boundaries (TBs) and grain boundaries (GBs), respectively. A comparative study about the different effects of grain refinements by GBs and by TBs on tension-compression yield asymmetry was performed. Our results show that both the refinements by GBs and by TBs increase the tensile and compressive yield strengths, but to a dif...

The effect of grain boundaries (GBs), in particular twin boundaries (TBs), on CdTe polycrystalline thin films is studied by conductive atomic force microscopy (C-AFM), electron-beam-induced current (EBIC), scanning Kelvin probe microscopy (SKPM), electron backscatter diffraction (EBSD), and scanning transmission electron microscopy (STEM). Four types of CdTe grains with various densities of {11...
