The breakdown of self-incompatibility, which could result from the accumulation of non-functional S-haplotypes or competitive interaction between two different functional S-haplotypes, has been studied extensively at the molecular level in tetraploid Rosaceae species. In this study, two tetraploid Chinese cherry (Prunus pseudocerasus) cultivars and one diploid sweet cherry (Prunus avium) cultiv...
A main challenge for structural biologists is to understand the mechanisms that discriminate between molecular interactions and determine function. Here, we show how partner recognition of the AXH domain of the transcriptional co-regulator ataxin-1 is fine-tuned by a subtle balance between self- and hetero-associations. Ataxin-1 is the protein responsible for the hereditary spinocerebellar atax...
The 20S core particle of the eukaryotic proteasome is composed of two α- and two β-rings, each of which is a hetero-heptamer composed of seven homologous but distinct subunits. Although formation of the eukaryotic proteasome is a highly ordered process assisted by assembly chaperones, α7, an α-ring component, has the unique property of self-assembling into a homo-tetradecamer. We used biophysic...
Atomically thin transition-metal dichalcogenides (TMD) hold promise for making ultrathin-film photovoltaic devices with a combination of excellent photovoltaic performance and mechanical flexibility. However, reported absorption for photovoltaic cells based on two dimensional materials (2D) materials is still just a few percent of the incident light due to their sub-wavelength thickness leading...
We consider the formation of droplets from a 2-component liquid mixture induced by large polymer chain that has preferential attraction to one components. assume is in fully miscible state, but far above critical interaction limit two species. show coil acts as chemical potential trap, which can shift inside volume into partially state and thus triggers polymer-bound droplet preferred solvent p...
The identification of protein-protein interaction sites is essential for the mutant design and prediction of protein-protein networks. The interaction sites of residue units were predicted using support vector machines (SVM) and the profiles of sequentially/spatially neighboring residues, plus additional information. When only sequence information was used, prediction performance was highest us...
The identi®cation of protein±protein interaction sites is essential for the mutant design and prediction of protein± protein networks. The interaction sites of residue units were predicted using support vector machines (SVM) and the pro®les of sequentially/spatially neighboring residues, plus additional information. When only sequence information was used, prediction performance was highest usi...
A Silicon tunnel FET with Si1-x Gex source is investigated and optimized for improved performance. In order to optimize the device performance, Germanium mole fraction and the length of the SiGe region is varied and the optimum values are obtained. Moreover, the source/channel hetero-junction is assumed graded. The grading distance is varied from zero (abrupt hetero-junction) to total channel l...

A nanocrystal memory using CoSi2/Si hetero-nanocrystals as floating gate was proposed. Numerical investigations on the writing, erasing and retention were performed. The hetero-structure provides an extra quantum well for the charge to achieve much longer retention time while maintains a writing/erasing speed similar to that of Si nanocrystal memory. 2005 Elsevier Ltd.
