Cubic boron nitride (c-BN) films were deposited using radio-frequency ~rf! magnetron sputtering. A type of turbostratic boron nitride (t-BN) growth was found by reducing the substrate bias during deposition. Transmission electron microscopy ~TEM! study showed that the t-BN served as a different nucleation environment for c-BN compared to those reported in the literature by many other groups. Th...

The thermal conductivity of boron nitride/ethylene glycol (BN/EG) nanofluids was investigated by transient hot-wire method and two abnormal phenomena was reported. One is the abnormal higher thermal conductivity enhancement for BN/EG nanofluids at very low-volume fraction of particles, and the other is the thermal conductivity enhancement of BN/EG nanofluids synthesized with large BN nanopartic...

For a finite n-element set X, n ≥ 1, let N [X] denote the number of elements of X and let p(n) denote the number of all partitions of X. If Bn is a Boolean algebra with n atoms, let A(Bn) be the set of all atoms of Bn. It is known that there exists a bijective correspondence between the set S(Bn) of all subalgebras of Bn and the set of all partitions of A(Bn), i.e., N [S(Bn)] = p(n). The follow...

For p > 0, let (Bn) and p(Bn) denote, respectively, the p-Bloch and holomorphic p-Lipschitz spaces of the open unit ball Bn in Cn. It is known that (Bn) and 1−p(Bn) are equal as sets when p ∈ (0,1). We prove that these spaces are additionally normequivalent, thus extending known results for n= 1 and the polydisk. As an application, we generalize work byMadigan on the disk by investigating bound...

Abstract Background Bacterial microleakage is an important cause of apical periodontitis and endodontic treatment failure. This study aimed to assess the bacterial nano-mineral trioxide aggregate (nano-MTA) as a sealer, Endoseal MTA, GuttaFlow Bioseal sealers in atmospheric pressure, simulated underwater diving aviation conditions. Methods In this vitro, experimental study, 180 extracted single...

A new thermally conductive polyimide composite film has been developed. It is based on a dispersion of different particle sizes of boron nitride (BN) in a polyimide (PI) precursor, polyamic acid (PAA). Subsequently, thermal imidization of PAA at 350 degrees C produced the corresponding polyimide composites. 3-Mercaptopropionic acid was used as the surfactant to modify the BN surface for the dis...

In recent years, the number of studies investigating new directions in speech modeling that goes beyond the conventional HMM has increased considerably. One promising approach is to use Bayesian Networks (BN) as speech models. Full recognition systems based on Dynamic BN as well as acoustic models using BN have been proposed lately. Our group at ATR has been developing a hybrid HMM/BN model, wh...
