Melon's fruit skin quality is an agriculturally important and consumer-appealing trait. To identify molecular markers associated with fruit skin qualities, including reticulation and color, a total of 1200 Insertion/Deletion (InDel) markers randomly selected from the whole genome re-sequencing data of melon were combined with bulk segregant analysis to analyze a panel of melon genetic resources presenting reticulated- and smooth-skinned fruits as well as varying fruit skin colors. Four DNA bulks, including reticulated skin DNA bulk, smoothed skin DNA bulk, green skin DNA bulk, as well as white skin and light yellow skin DNA bulks, were developed. Four DNA pools were created by combining the DNA of 12 representative plants from each DNA bulk for polymorphism analysis, and 200 polymorphic InDel markers were selected. These polymorphic markers were used to characterize typical genetic bands within each DNA bulk. Two InDel markers, MC8-52 and MC4-7, were discovered to be related to fruit surface patterning (reticulated- and smooth-skinned fruits) and fruit color (green and white–light yellow fruits), respectively. These markers offer a high degree of detection accuracy. InDel marker MC8-52 on chromosome 8 achieved detection accuracies of 78.33% and 90.56%, whereas marker MC4-7 on chromosome 4 displayed detection accuracies of 92.92% and 83.35%, respectively. However, these markers were seen as a likely means of identifying strongly related markers for these traits. Hence, a high-resolution map of genomic regions carrying them is required for the development of highly linked markers for these traits.

UV photoexcitation of trans-(η4-BDA)Fe(CO)3 (1) in alkane solvent generated a short-lived isomeric species whose identity was confirmed by infrared spectroscopy and supported by DFT calculations. This intermediate (2) exhibits an unusual ɳ2 coordination of the benzyl group to a vacant site on the iron center and is computed to be 7.8 kcal/mol less stable than 1. While thermal substitution of the BDA ligand from 1 by phosphites was found to be very slow at room temperature, photolysis of 1 in the presence of P(OEt)3 results in BDA displacement from 2 within seconds. Intermediate 2 may be of relevance in the previously reported photocatalyic dehydrogenation of formic acid by 1.

The deposition of boron nitride nanomaterials and ultrathin films in high vacuum conditions (1×10 −6 –1×10 −3 Torr) using molecular borazine as well as pre-dissociated borazine has been investigated with the motivation of studying the nucleation efficiency of BN under high vacuum conditions. Molecular borazine displays negligible sticking probability on Si(1 1 1) 7×7 at room temperature. Pre-adsorbing the borazine on silicon at 140 K and subsequent annealing is effective in forming ultrathin hexagonal films on the sample. It is possible to nucleate BN nanomaterials on nickel-sputtered silicon with high efficiency if the borazine is first discharged in a radio-frequency plasma to form reactive radicals. High quality crystalline h-BN thin films, as well as BN nanotubes can be formed on nickel via this approach.

Many high J pure rotational lines of HeD+ in the mid-infrared region up to and above the asymptotic dissociation threshold have been detected in a D2/He ac glow discharge. Eighteen transitions belonging to the v=0 and v=1 levels were identified, including two bound-to-quasibound and one quasibound-to-quasibound transition. The highest quasibound level involved in the observed spectrum (v=0, J=34) is over 2000 cm−1 above the dissociation limit. A least-squares fit of the data to the rotational term expression of a linear 1 Σ + molecule yielded spectroscopic constants for HeD+ up to the distortion constant Nv.

Infrared absorption spectra of the four common isotopic forms of the transient molecule BBr (11B79Br, 11B81Br, 10B79Br, and 10B81Br) have been observed in natural abundance. The spectra were detected in the region between 650 and 720 cm-1 using diode laser spectroscopy of a BBr3/He ac discharge. Over 150 lines consisting of both fundamental and hot bands up to v" = 5 have been fitted to Watson's isotopically invariant coefficients (Ukl). Spectroscopic parameters for each isotopomer could be derived from these coefficients; for 11B79Br, omegae = 685.1892(15) cm-1 and omegaexe = 3.73632(95) cm-1. The equilibrium dissociation energy obtained from Dunham's expanded Morse potential is 32 711(43) cm-1. Copyright 1998 Academic Press.

Electrical impedance tomography (EIT), as a relatively new medical imaging method, has desirable advantages of being inexpensive, safe, non-invasive and portable. Complementary to existing methods, it is expected to reconstruct accurate images of impedance changes from the sensor arrays surrounding the boundary. One of the approaches to producing an accurately reconstructed image of the object in question is the inclusion of prior information combined with the structure property and the conductivity contribution information of the object. In this research, structural model is researched, the mesh of the human thorax is automatically refined and a sensitivity matrix incorporating the structural information is calculated. On accomplishment of the conjugate gradient(CG) algorithm, the lung ventilation images are reconstructed, the visualization results and the sensitivity distributions of the structural model make significant improvements in image quality. In addition to the imaging of the overall resistivity distribution within the thorax, the relative resistivity changes traced with the ventilation are analyzed, the acidic activities can be figured out in the ventilation periods.

This study has presented a new classifier - the Partial Least Squares (PLS) classifier including linear and nonlinear based on the Partial Least-Squares Regression theory, then explained the classification algorithm and process of this new classifier, and finally, them have been applied to classify Landsat TM remote sensing data. Results of PLS linear classifier showed that there exist many classify mistake among six kinds of land use types. On the contrary, the nonlinear classifier based on Gaussian kernel function got better classification result, the overall classification accuracy is 79.297% and overall Kappa statistics is 0.74213. So, to remote sensing classification, the nonlinear PLS classifier is basic feasible, however, it is necessary for us to improve its algorithms or learning process further.
