Theoretical investigation of the structural and spectroscopic properties of expanded metalloporphyrin complexes [PDF]

open access: yesRoyal Society Open Science, 2019
The frontier molecular orbitals, UV–Vis absorption spectra, charge transfer (CT) and triplet excited states of 12 expanded D–A porphyrin/benzoporphyrin complexes were investigated using the density functional theory (DFT) method and time-dependent DFT in

A dearth of small particles in debris disks: An energy-constrained smallest fragment size [PDF]

open access: yes, 2014
A prescription for the fragment size distribution resulting from dust grain collisions is essential when modelling a range of astrophysical systems, such as debris disks and planetary rings.

An efficient method for noninvasive prenatal diagnosis of fetal trisomy 13, trisomy 18, and trisomy 21.

open access: yesPLoS ONE, 2019
BackgroundMolecular size determination of circulating free fetal DNA in maternal plasma is an important detection method for noninvasive prenatal testing (NIPT). The fetal DNA molecule is the primary factor determining the overall performance of NIPT and

Synergistic effects of climate change and habitat fragmentation on species range shifts and metapopulation persistence [PDF]

open access: yesFrontiers of Biogeography, 2018
The effects of climate and landscape change on biodiversity are relatively well described. However, there is limited understanding of the interactions between these processes, which generally operate at differing spatial scales. My objective was to evaluate the synergistic effects of climate and landscape changes on persistence and range shift dynamics.

Investigation of collective radial expansion and stopping in heavy ion collisions at Fermi energies [PDF]

open access: yes, 2013
We present an analysis of multifragmentation events observed in central Xe+Sn reactions at Fermi energies. Performing a comparison between the predictions of the Stochastic Mean Field (SMF) transport model and experimental data, we investigate the impact

Arthroscopic treatment of tibial intercondylar eminence fractures in skeletally immature patients with bioabsorbable nails

open access: yesLa Pediatria Medica e Chirurgica, 2022
Fractures involving tibial eminence caused by ACL avulsion lesion most frequently occur paediatric patients. Satisfactory reduction in displaced fractures cannot be achieved through conservative treatment, while arthroscopy-assisted fixation technique ...

Simultaneous Screening and Determination of Eleven Mycotoxins in Tomato by Ultra-high Performance Liquid Chromatography-Quadrupole/Orbitrap High-Resolution Mass Spectrometry [PDF]

open access: yesShipin Kexue, 2023
A method was developed for the simultaneous screening and determination of eleven mycotoxins in tomato by ultra-high performance liquid chromatography-quadrepole/orbitrap high-resolution mass spectrometry (UPLC-Q/Orbitrap HRMS).

AggLb Is the Largest Cell-Aggregation Factor from Lactobacillus paracasei Subsp. paracasei BGNJ1-64, Functions in Collagen Adhesion, and Pathogen Exclusion In Vitro. [PDF]

open access: yesPLoS ONE, 2015
Eleven Lactobacillus strains with strong aggregation abilities were selected from a laboratory collection. In two of the strains, genes associated with aggregation capability were plasmid located and found to strongly correlate with collagen binding. The

Chandra's Close Encounter with the Disintegrating Comets 73P/2006 (Schwassmann--Wachmann--3) Fragment B and C/1999 S4 (LINEAR) [PDF]

open access: yes, 2008
On May 23, 2006 we used the ACIS-S instrument on the Chandra X-ray Observatory (CXO) to study the X-ray emission from the B fragment of comet 73P/2006 (Schwassmann-Wachmann 3) (73P/B).
