This article presents the results of an AXB discrimination task testing the ability of Japanese beginner learners to distinguish three French nasal vowels /ɑ ̃ɔ ̃ɛ/̃ and compares them with the results of a corpus-based analysis of their production of the same vowels in two tasks (wordlist repetition and wordlist reading). This perception-production study is embedded in an ongoing 2-year longitudin...

Conjugated polymers in the solid state usually exhibit low fluorescence quantum yields, which limit their applications in many areas such as light-emitting diodes. Despite considerable research efforts, the underlying mechanism still remains controversial and elusive. Here, the nature and properties of excited states in the archetypal polythiophene are investigated via aggregates suspended in s...

The major replicative DNA polymerases of S. cerevisiae (Pols α, δ, and ɛ) incorporate substantial numbers of ribonucleotides into DNA during DNA synthesis. When these ribonucleotides are not removed in vivo, they reside in the template strand used for the next round of replication and could potentially reduce replication efficiency and fidelity. To examine if the presence of ribonucleotides in ...

The paper investigates the developmental change in formant frequencies (F1F2) of the vowels [i u ɛ ɔ a] in Cantonese male and female children of the ages ranging from 4 to 12. Results show that (i) a decrease in formant frequencies and vowel loop area is a function of age and the change is a gradual process; (ii) the developmental change with age is non-uniform across vowel types and formants, ...

We consider a one-dimensional system with particles having either positive or negative velocity, and these particles annihilate on contact. Diffusion is superimposed on the ballistic motion of the particle. The annihilation may represent a reaction in which the two particles yield an inert species. This model has been the subject of previous work, in which it was shown that the particle concent...

[1] This study presents vertical profiles of turbulence parameters obtained in the upper 100 m of the northeastern Atlantic Ocean along a transect from tropical permanently stratified waters to subpolar seasonally stratified waters in July–August 2009. The focus is to fully characterize the vertical mixing along this transect for further studies related to phytoplankton and nutrient distributio...

We prove for every graph H there exists ɛ > 0 such that, G with |G|≥2, if no induced subgraph of is a subdivision H, then either some vertex has at least ɛ|G| neighbours, or are two disjoint sets A, B ⊆ V(G) |A|,|B|≥ɛ|G| that edge joins A and B. It follows c>0 G, its complement clique stable set cardinality |G|c. This related to the Erdős-Hajnal conjecture.

We study polymer translocation through a nanopore subject to conformational differences created by putting two different solvents at the cis and trans compartments using Langevin dynamics in three dimensions (3D). Initially a fraction of the chain is placed in a good solvent at the cis side and the rest of the chain at the trans side is immersed in a bad solvent where it forms a globule. We stu...
