PMID: 20496692
Guang Pu Xue Yu Guang Pu Fen Xi. 2010 Mar;30(3):706-9.

Taking ponceau 4R and amaranth as an example, concentration prediction and kind identification of synthetic food colors by fluorescence spectroscopy and radial basis function neural networks are introduced. By using SP-2558 multifunctional spectral measuring system, the fluorescence spectra were...

Reactions of CrCl(2)(THF)(2) with N-aryl-9,10-iminophenanthraquinone in CH(2)Cl(2) give the monoimine chromium complexes (Ar)IPQCrCl(2)(THF)(2) (1, Ar = 2,6-Me(2)C(6)H(3); 2, Ar = 2,6-Et(2)C(6)H(3); 3, Ar = 2,6-(i)Pr(2)C(6)H(3)). Molecular structures of 1 and 3 were revealed to be monomeric with the chromium...

Multiphoton quantum states play a critical role in emerging quantum technologies and greatly improve our fundamental understanding of the quantum world. Integrated photonics is well recognized as an attractive technology offering great promise for the generation of photonic quantum...

Temporal trend of polychlorinated biphenyls contamination in the northwestern Arabian Gulf - Evidence from sediment records.

Marine pollution bulletin

Gevao B, Uddin S, Behbehani M, Fowler SW.
PMID: 34959104
Mar Pollut Bull. 2021 Dec 24;174:113265. doi: 10.1016/j.marpolbul.2021.113265. Epub 2021 Dec 24.

This study provides an insight into the polychlorinated biphenyls (PCBs) inventories in the sediments of the northwestern Arabian/Persian Gulf. PCBs can be used as chemical markers that correlate with historical events in the region, to estimate the sedimentation rates...

Lesions that do or do not impair digit span: a study of 816 stroke survivors.

Brain communications

Geva S, Truneh T, Seghier ML, Hope TMH, Leff AP, Crinion JT, Gajardo-Vidal A, Lorca-Puls DL, Green DW, Price CJ.
PMID: 33928246
Brain Commun. 2021 Mar 10;3(2):fcab031. doi: 10.1093/braincomms/fcab031. eCollection 2021.

Prior studies have reported inconsistency in the lesion sites associated with verbal short-term memory impairments. Here we asked: How many different lesion sites can account for selective impairments in verbal short-term memory that persist over time, and how consistently...

An Exponential Response Neural Net.

Neural computation

Geva S, Sitte J.
PMID: 31167339
Neural Comput. 1991;3(4):623-632. doi: 10.1162/neco.1991.3.4.623.

By using artificial neurons with exponential transfer functions one can design perfect autoassociative and heteroassociative memory networks, with virtually unlimited storage capacity, for real or binary valued input and output. The autoassociative network has two layers: input and memory,...

[The study of spectral characteristics of several organophosphate pesticides].

Guang pu xue yu guang pu fen xi = Guang pu

Chen C, Chen GQ, Gao SM, Kong FB, Li R, Huang QF.
PMID: 22870646
Guang Pu Xue Yu Guang Pu Fen Xi. 2012 Jun;32(6):1592-5.

Using Edinburgh FLS920P spectrometer, the authors obtained the UV-visible spectrum and fluorescence spectrum of parathion, metaphos and isocarbophos in their solution of methanol and ethanol respectively, and discussed their spectral characteristics and their mechanisms. Results show that they all...

[Photophysical properties of novel organic europium (III) complexes].

Guang Pu Xue Yu Guang Pu Fen Xi. 2010 Oct;30(10):2606-10.

Based on fluorescence and absorbance spectroscopy, the photophysical properties and mechanisms of novel organic europium (III) complexes in the case of different concentration in ethanol solution and solid flour were studied at room temperature. It was found that the...

Automated identification of brain tumors from single MR images based on segmentation with refined patient-specific priors.

Frontiers in neuroscience

Sanjuán A, Price CJ, Mancini L, Josse G, Grogan A, Yamamoto AK, Geva S, Leff AP, Yousry TA, Seghier ML.
