The specific interaction between 17 beta-estradiol-receptor complex and nuclear acceptors was analyzed by immobilizing various nuclear proteins to CNBr-activated agarose. The specific, high affinity sites identified in a fraction of basic proteins that can be solubilized from purified nuclei of calf uterus (Puca, G.A., Sica, V., and Nola. E (1974) Proc. Natl. Acad. Sci. U.S.A. 71, 979-983) were...

This study demonstrates the use of decision tree classifiers as the basis for a general gene-finding system. The system uses a dynamic programming algorithm that finds the optimal segmentation of a DNA sequence into coding and non-coding regions (exons and introns). The optimality property is dependent on a separate scoring function that takes a subsequence and assigns to it a score reflecting ...

The design of orange-light emitting, thermally activated, delayed fluorescence (TADF) materials is necessary and important for the development and application of organic light-emitting diodes (OLEDs). Herein, two donor-acceptor-donor (D-A-D)-type orange TADF materials based on fluorenone and acridine, namely 2,7-bis(9,9-dimethylacridin-10(9H)-yl)-9H-fluoren-9-one (27DACRFT, 1) and 3,6-bis(9,9-di...

Despite the recent development of several super-resolution fluorescence microscopic techniques, there are still few techniques that can be readily employed in conventional imaging systems. We present a very simple, rapid, general and cost-efficient super-resolution imaging method, which can be directly employed in a simple fluorescent imaging system with general fluorophores. Based on diffusion...

This paper presents a new technique for modification of 3D terrains by hydraulic erosion. It efficiently couples fluid simulation using a Lagrangian approach, namely the Smoothed Particle Hydrodynamics (SPH) method, and a physically-based erosion model adopted from an Eulerian approach. The eroded sediment is associated with the SPH particles and is advected both implicitly, due to the particle...

We explain the robust p-type doping observed for quasi-free-standing graphene on hexagonal silicon carbide by the spontaneous polarization of the substrate. This mechanism is based on a bulk property of SiC, unavoidable for any hexagonal polytype of the material and independent of any details of the interface formation. We show that sign and magnitude of the polarization are in perfect agreemen...

The imidazole unit is chemically stable and ubiquitous in biological systems; its proton donor and acceptor moieties easily bind molecules into a dipolar chain. Here we demonstrate that chains of these amphoteric molecules can often be bistable in electric polarity and electrically switchable, even in the crystalline state, through proton tautomerization. Polarization-electric field (P-E) hyste...

We demonstrate the growth of phosphorus doped Zn(1-x)Mg(x)O nanowire (NW) using pulsed laser deposition. For the first time, p-type Zn(0.92)Mg(0.08)O:P NWs are likely obtained in reference to atomic force microscopy based piezoelectric output measurements, X-ray photoelectron spectroscopy, and the transport property between the NWs and a n-type ZnO film. A shallow acceptor level of approximatel...

Si and N-doped DLC coatings with various Si and N contents were prepared using a magnetron sputter ionplating technology. The antifouling property of DLC coatings was evaluated with Pseudomonas fluorescens which is one of the most common bacteria forming biofilms on the surface of heat exchangers in cooling water systems. The experimental results showed that bacterial removal by a standardised ...

Alkyl chains engineering plays an important role in photovoltaic materials for organic solar cells. Herein, three A-DA'D-A (acceptor–donor–acceptor'–donor–acceptor) type acceptors named Y6, Y6-C4, and Y6-C5 with different branching position on the pyrrole motif are discussed relationship between molecular aggregation, crystalline, device performance systematically investigated. The distance mai...
