In 2 experiments, 3V2-year-old children interpreted a novel count noun (e.g., "This is a murvil") applied to an unfamiliar stuffed animal as referring to a basic-level kind, rather than to a kind that individuates its members by type of situation (context or life-phase). For example, children made interpretations akin to PERSON (a basic-level kind) rather(More)
Three experiments explored preschoolers' and adults' understanding of the distinctive semantic functions of adjectives (i.e., to name properties) and count nouns (i.e., to name object kinds). In Experiment 1, we modeled a familiar adjective (e.g., "blue") syntactically as either an adjective (e.g., "This is a blue one") or a count noun (e.g., "This is a(More)
We examined the role of object kind familiarity (i.e., knowledge of a count noun for an object) on preschoolers' sensitivity to the relation between a novel word's form class (adjective or count noun) and its reference (to a material kind-property or to an object kind). We used a forced-choice match-to-target task, in which children learned a word for one(More)
Recent research suggests that, although young children appreciate many different kinds of conceptual relations among objects, they focus specifically on taxonomic relations in the context of word learning. However, because the evidence for children's appreciation of this linkage between words and object categories has come primarily from children who have(More)
We report on the design, fabrication, and measurement of ultrathin film a-Si:H solar cells with nanostructured plasmonic back contacts, which demonstrate enhanced short circuit current densities compared to cells having flat or randomly textured back contacts. The primary photocurrent enhancement occurs in the spectral range from 550 nm to 800 nm. We use(More)
Single frequency lasing from organic dye solutions on a monolithic poly(dimethylsiloxane) (PDMS) elastomer chip is demonstrated. The laser cavity consists of a single mode liquid core/PDMS cladding channel waveguide and a phase shifted 15th order distributed feedback (DFB) structure. A 1mM solution of Rhodamine 6G in a methanol and ethylene glycol mixture(More)
All fiber lasers to date emit radiation only along the fiber axis. Here a fiber that exhibits laser emission that is radially directed from its circumferential surface is demonstrated. A unique and controlled azimuthally anisotropic optical wave front results from the interplay between a cylindrical photonic bandgap fiber resonator, anisotropic organic dye(More)
Infections with the bacteria Burkholderia cepacia complex (Bcc) are very difficult to eradicate in cystic fibrosis patients due the intrinsic resistance of Bcc to most available antibiotics and the emergence of multiple antibiotic resistant strains during antibiotic treatment. In this work, we used a whole-cell based assay to screen a diverse collection of(More)
A small library of 30 thiomarinol analogues was successfully synthesised using as a key step–a catalytic enantioselective tandem oxa[4+2] cycloaddition/aldehyde allylboration methodology. With this method, highly substituted $$\alpha $$ α -hydroxyalkyl dihydropyrans were assembled in a single three-component reaction utilizing three different enol ethers(More)
