In order to expand the use of ZnO in advanced display and lighting device applications, such as distinguishable emissive flat panel displays and liquid crystal display backlights, Eu³⁺/Dy³⁺-codoped ZnO nanocrystals were synthesized using a low temperature wet chemical doping technique and chemical surface modification. X-ray diffraction patterns revealed that co-doping Eu³⁺ and Dy³⁺ does not change the wurtzite structure of ZnO. A high-resolution TEM image showing obvious lattice fringes confirmed the high crystallinity of the nanosized sample...

REVIEW
José Barberán, José Mensa
Invasive pulmonary aspergillosis (IPA) is a common infection in immunocompromised patients with hematological malignancies or allogenic stem cell transplantation, and is less frequent in the context of chronic obstructive pulmonary disease (COPD). Mucociliary activity impairment, immunosuppression due to the inhibition of alveolar macrophages and neutrophils by steroids, and receiving broad-spectrum antibiotics, play a role in the development of IPA in COPD patients. Colonized patients or those with IPA are older, with severe CODP stage (GOLD≥III), and have a higher number of comorbidities...

This work reports the intense emissions at 2.7 and 2.84 μm in a Ho³⁺/Er³⁺-codoped fluoride glass (ZrF₄-BaF₂-YF₃-AlF₃). An extensive transmission spectrum and the absence of strong OH⁻ absorption guarantee the observation of mid-infrared (IR) emissions. For the Ho³⁺/Er³⁺-codoped sample, the 2.7- and 2.84-μm emissions are 5.8 and 3.8 times higher with larger emission cross-sections (10.2×10⁻²¹ and 9.8×10⁻²¹ cm²), respectively. Meanwhile, other near to middle infrared emissions (1200, 2045 nm emissions from Ho³⁺ and 980, and 1535 nm emissions from Er³⁺ ions) are all enhanced...

In mass customization logistics service, reasonable scheduling of the logistics service supply chain (LSSC), especially time scheduling, is benefit to increase its competitiveness. Therefore, the effect of a customer order decoupling point (CODP) on the time scheduling performance should be considered. To minimize the total order operation cost of the LSSC, minimize the difference between the expected and actual time of completing the service orders, and maximize the satisfaction of functional logistics service providers, this study establishes an LSSC time scheduling model based on the CODP...

BACKGROUND: Lynch syndrome is a hereditary cancer predisposition syndrome caused by a mutation in one of the DNA mismatch repair (MMR) genes. About 24% of the mutations identified in Lynch syndrome are missense substitutions and the frequency of missense variants in MSH6 is the highest amongst these MMR genes. Because of this high frequency, the genetic testing was not effectively used in MSH6 so far. We, therefore, developed CoDP (Combination of the Different Properties), a bioinformatics tool to predict the impact of missense variants in MSH6...

In the present study, the performance of a membrane bioreactor (MBR) was modelled using a hybrid approach based on the activated sludge model number 3 (ASM3) combined with projection to latent structures (PLS) to predict the residuals of the ASM. The application of ASM to MBRs requires frequent re-calibration to adjust the model to variations in influent characteristics, determined through time-consuming analysis and batch tests. Considering this problem, the objective of this study was to improve ASM prediction ability with minimal additional monitoring effort...

Chronic obstructive pulmonary disease (COPD), a complex disease triggered mostly by exposure to cigarette smoke, is a leading cause of morbidity and mortality worldwide, leading not only to pulmonary damage but also to systemic impairment. There is growing awareness of systemic inflammation and cardiovascular, neurologic, psychiatric, and endocrine comorbidities associated with COPD. The diagnosis of CODP is based upon the clinical presentation, measurement of the pulmonary function, investigation of comorbidities and exclusion of differential diagnoses...

Two serial Dy(3+)-doped and Dy(3+), Tm(3+)-codoped (100-x)(0.8GeS(2).0.2Ga(2)S(3)).xCdI(2) (0<or=x<or=20) chalcohalide glasses were prepared and characterized. By analyzing the absorption and emission measurements of the two serial chalcohalide glasses with the Judd-Ofelt analysis, we were able to calculate its Judd-Ofelt strength parameters Omega t (t = 2, 4, 6), transition probabilities, exited state lifetimes, branching ratios, and emission cross-sections. In the Dy(3+)-doped glasses, increase of CdI(2) had positive effect up to 1330 nm fluorescence and the emission cross section (sigma emi) was estimated to be 4...
