The objective of this study was to investigate the performance of 3 brain-computer interface (BCI) paradigms in an amyotrophic lateral sclerosis (ALS) population (n = 11). Using a repeated-measures design, participants completed 3 BCI conditions: row/column (RCW), checkerboard (CBW), and gray-to-color (CBC). Based on previous studies, it is hypothesized that the CBC and CBW conditions will resu...

We suggest that the unique X-ray source 1E161348-5055 at the centre of the supernova remnant RCW 103 consists of a neutron star in close orbit with a low mass main sequence star. The time signature of 6.67 hr is interpreted as the neutron star’s spin period. This requires the neutron star to be endowed with a high surface magnetic field of ∼ 10 G. Magnetic or/and material (propeller) torques ar...

We present the first results of our VLT observation campaign of the Central Compact Objects (CCOs) in SNRs RX J085201.4-461753 (Vela Jr), 1E 1648-5051 (RCW 103) and RX J171328.4-394955 (G347.3-0.5). For Vela Jr., we found that the source is embedded in a compact optical nebulosity, possibly a bow-shock or a photo-ionization nebula, and we identified a candidate IR counterpart to the CCO. For RC...

The discovery of the 6.67 hr periodicity in the X-ray source 1E 161348−5055 associated with the supernova remnant RCW 103 has raised interesting suggestions about the nature of the X-ray source. Here we argue that in either accreting neutron star or magnetar model, a supernova fallback disk may be a critical ingredient in theoretical interpretations of 1E 161348−5055. We further emphasize the e...

We report on the discovery of an unresolved X-ray source inside the supernova remnant G315.4-2.3 (RCW 86). The source is located 7 to the Southwest of the geometrical centre and may be close to the actual explosion centre of the supernova, which makes this a candidate for the stellar remnant associated with RCW 86. However, the presence of a possible optical counterpart with V ∼ 14 at 3 from th...

Recent studies of narrow, X-ray synchrotron radiating filaments surrounding young supernova remnants indicate that magnetic fields strengths are relatively high, B ∼ 0.1 mG, or even higher, and that diffusion is close to the Bohm limit. I illustrate this using Cas A as an example. Also older remnants such as RCW 86 appear to emit X-ray synchrotron radiation, but the emission is more diffuse, an...

In the present work, the fermentation process aimed at obtaining bio-ethanol starting from ricotta cheese whey (RCW), a waste biomass rich in lactose, was simulated by both a pure neural network model (NM) and a multiple hybrid neural model (HNM). The simulation results showed that the developed HNM was capable of providing an accurate representation of the actual time evolution of lactose, eth...

Abstract The current focus of the metamaterials is to further improve their performance by unit cell innovation, while for auxetic metamaterials, compromise between mechanical properties and effect still needs more efforts. Given this issue, here we developed a novel honeycomb, named re-entrant combined-wall (RCW) introducing four hierarchical substructures RE cell. Analytical expressions were ...

This study investigated the load bearing capacity of intraradicular posts and core materials under static dynamic loading. Human teeth with single root (N = 154, n 14 per sub group) were endodontically prepared randomly divided into six groups: CON: Sound premolars; TP: Titanium post (Flat Head T); FRCP: Indirect E-glass FRC (FRC Postec Plus); FRCC: Fiber-reinforced resin composite (Everex Post...
