Context. Secondary stars in dwarf novae are strongly irradiated during outbursts. It has been argued that this could result in an enhancement of the mass transfer rate even though the L1 region is shadowed from the primary irradiation by the accretion disc. Previous investigations of the possibility of a circulation flow transporting heat from hot regions to L1 gave opposite answers. Aims. We i...

Locative inversion is a non-canonical structure in Chinese and English. According to the Contrastive Analysis theory (Lado, 1957), a structure in L2 is easier to learn if it has the same meaning and distribution as an “equivalent” in L1. Previous studies suggest that English-speaking Chinese L2 learners would have no difficulty in acquiring the unmarked construction (Jin, 2008). The present stu...

The synthesis and Zn(2+) coordination properties of a new macrocycle (L1) obtained by dipodal (2 + 2) condensation of the polyamine 3-(naphthalen-2-ylmethyl)pentane-1,5-diamine with 1H-pyrazole-3,5-dicarbaldehyde are reported. pH-metric studies show that L1 bears five measurable protonation steps in the 2.0-11.0 pH range. Fluorescence emission studies indicate that the removal of the first prot...

We will use the concept of strong generating and a simple renorming theorem to give new proofs to slight generalizations of some results of Argyros and Rosenthal on weakly compact sets in L1(μ) spaces for finite measures μ. The purpose of this note is to show that a simple transfer renorming theorem explains why L1(μ)-spaces, for finite measures μ, share some properties with superreflexive spac...

This study is an investigation of L2 speakers’ production of the pharyngeal gesture in the English /ɹ/. Real-time MRI recordings from one L1 French/L2 English and one L1 Greek/L2 English speaker were analyzed and compared with recordings from a native English speaker to examine whether the gestural composition of the rhotic consonant(s) in a speaker’s L1, particularly the presence and location ...

The task of native language (L1) identification suffers from a relative paucity of useful training corpora, and standard within-corpus evaluation is often problematic due to topic bias. In this paper, we introduce a method for L1 identification in second language (L2) texts that relies only on much more plentiful L1 data, rather than the L2 texts that are traditionally used for training. In par...

PURPOSE To assess the influence of second language (L2) proficiency on production characteristics of rhythmic sequences in the L1 (Bengali) and L2 (English), with emphasis on linguistic transfer. One goal was to examine, using kinematic evidence, how L2 proficiency influences the production of iambic and trochaic words, focusing on temporal and spatial aspects of prosody. A second goal was to a...

The present study examines the interface between syntax and discourse-pragmatics in the production of verb second (V2) structures in a corpus of English texts by advanced L1 German and Dutch speakers. The evidence shows that the residual V2 produced by the learner groups studied is the result of a deficit at the interface rather than the transfer of narrow V2 syntax per se. The analysis offered...

Programmed death-1 (PD-1), an inhibitory receptor up-regulated on activated T cells, has been shown to play a critical immunoregulatory role in peripheral tolerance, but its role in alloimmune responses is poorly understood. Using a novel alloreactive TCR-transgenic model system, we examined the functions of this pathway in the regulation of alloreactive CD4+ T cell responses in vivo. PD-L1, bu...
