The novel assessment tool Cross-Linguistic Lexical Tasks (LITMUS-CLT) aims for comparable cross-linguistic assessment of multilingual children's lexical skills by basing each language version on two language-specific variables: age of acquisition (AoA) and complexity index (CI), a novel measure related to phonology, morphology, exposure and etymology. This article investigates the validity of this methodology, asking whether the underlying properties are robust predictors of children's performance. The Polish and Norwegian CLTs were used to assess 32 bilingual Polish-Norwegian, 34 monolingual Norwegian and 36 monolingual Polish children...

The use of organosilane chains to link carbon nanodots (CDs) through organosilane surface functional groups is proposed to improve the efficiency of multiphoton absorption. As a result, a large absorption coefficient of 1.16 × 10(-6) cm(5) per GW(3) is obtained and four-photon luminescence under 1900 nm excitation is observed from the CDs at room temperature. Furthermore, a CD laser, which demonstrates random lasing under three-photon (i.e. 1400 nm) excitation, can be realized by sandwiching a CD film between a quartz substrate and a dielectric mirror...

Carbon dot (CD)-based multifunctional delivery systems have shown great potential in both drug/gene delivery and bio-imaging. In this work, we present a strategy to simply construct amphiphilic CDs (ACDs) by conjugating hydrophobic alkyl epoxide to the surface amino groups of PEI 600-derived CDs. ACDs could well dissolve in water or organic solvents and emit bright fluorescence both in solutions and cells. (1)HNMR also suggested that ACDs may form micelle-like structures in water, and their CMC could be determined...

Camels have exceptional carbohydrate metabolism as their plasma glucose level is high and have low whole body insulin sensitivity, similar to that observed in type 2 diabetes patients. We aimed at studing an important component of insulin signalling pathway, the GLUT4, in camel. Camelus dromedarius GLUT4 (CdGLUT4) CDS is 1530 nucleotide in length that encodes for a 55KDa protein. CdGLUT4 has 23 amino acid substitutions and 3N-glycosylation sites, compared to 2 in Human GLUT4. 3 D structures of CdGLUT4 and HsGLUT4 generated by homology modelling revealed conservation of characteristic signature motifs...

Along with the soaring prevalence of obesity and type 2 diabetes mellitus (T2DM) globally, metabolic and bariatric surgery (MBS) has been rapidly developing into a major surgical subspecialty. However, the indications, benefits and potential risks of MBS are still controversial so far. In September 2015, the 2nd Diabetes Surgery Summit (DSS-II() was successfully convened, and later on an international joint statement on metabolic surgery in the treatment algorithm for T2DM was released based upon the consensus reached in DSS-II(, aiming to serve as a new global clinical guideline...

Femtosecond optical pump-probe spectroscopy resolves hitherto unobserved coherent acoustic phonons in colloidal CdSe/CdS core/shell nanoplatelets (NPLs). With increasing pump fluence, the frequency of the in-plane acoustic mode increases from 5.2 to 10.7 cm(-1), whereas the frequency of the out-of-plane mode remains at ~20 cm(-1). Analysis of the oscillation phases suggests that the coherent acoustic phonon generation mechanism transitions from displacive excitation to sub-picosecond Auger hole trapping with increasing pump fluence...

Photocatalytic hydrogen (H2) evolution from water splitting is attracting enormous interest due to the possibility of converting solar energy into green chemical energy. The construction of highly efficient and stable photocatalysts is of importance and necessary for the development of photocatalytic water splitting technology. In this study, we have developed a self-template synthetic strategy for the preparation of heterostructured nanohybrids composed of ultrasmall CdS and NiSx nanoparticles by using Cd(ii)-Ni(ii)-(4,4'-bipyridine) coordination polymers as the precursor and template...

CdS quantum dot sensitized ZnFe2O4/ZnIn2S4 nanosheet stereoscopic films were synthesized through two sequential solvothermal processes and the ionic layer adsorption-reaction method. The hydrophilic ZnIn2S4 nanosheet stereoscopic film was pre-prepared to act as a suitable host material, and then ZnFe2O4 nanoparticles and CdS quantum dots were uniformly decorated on the surface of the ZnIn2S4 nanosheet stereoscopic film to form a ternary heterostructure stereoscopic film. The band structure difference in the ternary heterostructure can promote the spatial separation and transport efficiency of photogenerated charge carriers...

CdS/Si multi-interface nanoheterojunctions (CdS/Si-NPA) were fabricated by depositing CdS nanocrystallites (nc-CdS) on silicon nanoporous pillar arrays (Si-NPA) by chemical bath deposition. White electroluminescence (EL) with a high colour rendering index from a prototypical light emitting diode based on CdS/Si-NPA has been reported, which does not need complex colour mixing or conversion techniques. The white EL can be composed into three primary colours, which include blue emissions from the Si-NPA, the green emissions from the bandgap emission of nc-CdS and red emissions from the defects in the nc-CdS...

While adverse effects of nanoparticles on lung health have previously been proposed, few studies have addressed the direct effects of nanoparticle exposure on the airway epithelium. In this work, we examine the response of the pulmonary airway to nanoparticles by measuring intracellular Ca(2+) concentration ([Ca(2+)]i) in the Calu-3 epithelial layer stimulated by 3-mercaptopropionic-acid (3MPA) coated CdSe-CdS/ZnS core-multishell quantum dots (QDs). Simultaneous transient transepithelial electrical resistance (TEER) decrease and global [Ca(2+)]i increase in Calu-3 epithelial layer, accompanied by cell displacements, contraction, and expansion, were observed under QD deposition...

Cyclodextrins (CDs) are sugar-based cyclic oligosaccharides, which form inclusion complexes with small guest molecules through their hydrophobic cavity. Here we successfully synthesized highly porous poly-cyclodextrin (poly-CD) cryogels, which were produced under cryogenic conditions by the cross-linking of amine-functional CDs with PEG-based diepoxide cross-linker. The poly-CD cryogels showed aligned porous network structures owing to the directional freezing of the matrix, of which the pore size and architecture exposed variations depending on the composition of the reactants...
