Abstract: As a most natural realization of the Next-to Minimal Supersymmetry Standard Model (NMSSM), λ-SUSY is parameterized by a large λ around one and a low tan β below 10. In this work, we first scan the parameter space of λ-SUSY by considering various experimental constraints, including the limitation from the Higgs data updated by the ATLAS and CMS collaborations in the summer of 2014, then we study the properties of the Higgs bosons. We get two characteristic features of λ-SUSY in experimentally allowed parameter space. One is the triple self coupling of the SM-like Higgs boson may get enhanced by a factor over 10 in comparison with its SM prediction. The other is the pair production of the SM-like Higgs boson at the LHC may be two orders larger than its SM prediction. All these features seems to be unachievable in the Minimal Supersymmetric Standard Model and in the NMSSM with a low λ. Moreover, we also find that naturalness plays an important role in selecting the parameter space of λ-SUSY, and that the Higgs χ2 obtained with the latest data is usually significantly smaller than before due to the more consistency of the two collaboration measurements. © 2014, The Author(s).

Methamphetamine (METH) is second only to marijuana as a widely used illicit drug. We are presenting a simple colorimetric assay for sensitive and visual detection of METH in human urine using a METH-specific aptamer as the recognition element and unmodified gold nanoparticles as indicators. The method is based on the finding that the presence of METH results in AuNPs solution’s color change from red to blue. Normally, aptamers attach to the surface of AuNPs and thereby increasing their resistance to NaCl-induced aggregation. If, however, the aptamer bind to METH via G-quartets, rapid salt induced aggregation occurs associated with the formation of a blue colored solution. Urinary METH can be quantified via this effect either visually or by measurement of the absorbance ratios at 660 and 525 nm, respectively. It works in the 2 μM to 10 μM concentration range with a detection limit at 0.82 μM. The method is fast and also works well in human urine. It is believed to represent a widely applicable aptamer-based detection scheme. © 2014, Springer-Verlag Wien.

In this paper, using the intensity ratio between two spectral lines arising from the common lower level, we determine the optical depth of the solar atmosphere of CIV emission lines. The optical depth at the line center of the (1/2-3/2) component is calculated to be 0.05 at the center of the solar disc. By introducing a measured abundance of carbon and the results of ionization balance calculations, we estimate the line-of-sight physical thickness of the regions emitting CIV lines as Heff = 27 km, and we estimate the population density of the lower level to be 1.8 × 106 cm -3.

This paper, after excluding the impact of structural factors, studes the relationship between macroeconomic variables and bank credit risk by using the concept of cointegration time series. It finds that the co-integration between time of loans issuance and economic cycle does not exist. The economic cycle has a significant impact to the level of non-performing loans in point, and the co-integration relationship between the two is obvious. Credit scale has a significant long-run equilibrium relationship with economic cycle. © (2014) Trans Tech Publications, Switzerland.

In order to prove the data possession in the distributed storage systems and keep low repair bandwidth, this paper proposes a provable data possession algorithm based on regenerating codes. This scheme uses the regenerating codes to prove the data possession, and to prove the data possession a second time in repair phase for resisting the pollution attacks. The theoretical analysis shows that this scheme not only maintains the advantages of regenerating codes on low repair bandwidth, but also reduces the computational overhead and saves storage space compared with the classical scheme. Security proof is also provided in this paper showing that this scheme is feasible. ©, 2015, Nanjing University of Science and Technology. All right reserved.

In order to improve the image analysis ability in some practical applications, an image fusion algorithm was proposed. This algorithm combined information from multiple images of the same scene in pixel level. Firstly, a group of lifting morphological wavelets for image fusion was discussed. Then using one of the schemes, multiple images were shift in different direction and decomposed respectively. Next, the transform coefficients were processed according to certain fusion criterion and some fusion results could be obtained through inverse transform and inverse displacement. Finally, such fused images were filtered to be one image we need. Computer simulation shows this algorithm in morphological wavelet domain can fuse grayscale images or color images effectively. Compared with the conventional wavelet transform, it gets a more complete and clearer scene. © 2014 IEEE.

The tracking performance of JPDA-based algorithms will be decreased with the increase of sensors amount and clutter density. Thus it is necessary to find out a multi-sensor data fusion tracking algorithm which has lower computation and higher tracking accuracy. Since the motion direction of the targer is viewed as a key factor in data correlation, the pseudodirection tracking gate can be improved. The feature of location and speed are combined to reduce the amount of the related affairs, which can reduce the computation of JPDA algorithm. This idea is adopted to improve the FDA algorithm and a sequenced fast algorithm for data association based on double-gate tracking. The simulations proved that this method has legitimately limited the effective number of echoes, which ensures the accuracy of correlation and tracking. Its computation is less than original FDA algorithm with keeping and it has good performance for maneuvering target tracking. © 2013 ACADEMY PUBLISHER.

Sensor localization technology is the principle problem for configuration and operation of wireless sensor network. Since existing multidimensional scaling localization algorithm has its limitation in localization accuracy, a novel method based on node distance correction (DCMDS) is put forward. The improved multidimensional scaling-based sensor localization algorithm partly divides the location areas of the whole network. It achieves the relative position by distance information among the nodes. Then the distance estimations are corrected according to the distance information of anchor nodes. When the corrected estimations distance matrix is completed, relative position is recalculated with classical MDS algorithm. The optimized particle swarm optimization is used to acquire the final localization results. The performances of DCMDS algorithm were validated in different scenario. The experiments revealed that improved method has high accuracy in localization and low complexity for calculation and communication. It also enhances the extensibility of localization algorithms. © 2013 ACADEMY PUBLISHER.
