In this paper, a new fractional-order chaotic system was studied, and the basic dynamic properties of the new system were analyzed. The control of the new system in unstable equilibrium point was realized by designing the reasonable nonlinear controller. Further, we investigated the projective synchronization problem about fractional order chaotic systems with different dimensions, the appropriate controller was designed to achieve the projective synchronization of a four-dimensional drive system and a three-dimensional response system by reducing the dimension. With the numerical simulation of Matlab, the feasibility of the scheme was verified.

Currently, the systems for culturing buffalo spermatogonial stem cells (SSCs) in vitro are varied, and their effects are still inconclusive. In this study, we compared the effects of culture systems with undefined (foetal bovine serum) and defined (KnockOut Serum Replacement) materials on the in vitro culture of buffalo SSC-like cells. Significantly more DDX4- and UCHL1-positive cells (cultured for 2 days at passage 2) were observed in the defined materials culture system than in the undefined materials system (p < 0.01), and these cells were maintained for a longer period than those in the culture system with undefined materials (10 days vs. 6 days). Furthermore, NANOS2 (p < 0.05), DDX4 (p < 0.01) and UCHL1 (p < 0.05) were expressed at significantly higher levels in the culture system with defined materials than in that with undefined materials. Induction with retinoic acid was used to verify that the cultured cells maintained SSC characteristics, revealing an SCP3+ subset in the cells cultured in the defined materials system. The expression levels of Stra8 (p < 0.05) and Rec8 (p < 0.01) were significantly increased, and the expression levels of ZBTB16 (p < 0.01) and DDX4 (p < 0.05) were significantly decreased. These findings provided a clearer research platform for exploring the mechanism of buffalo SSCs in vitro.

After an earthquake, information regarding potential damage to buildings close to the epicenter is very important during the initial emergency response. This study proposes the use of crowdsourced measured acceleration response data collected from smartphones located within buildings to perform system identification of building structures during earthquake excitations, and the feasibility of the proposed approach is studied. The principal advantage of using crowdsourced smartphone data is the potential to determine the condition of millions of buildings without incurring hardware, installation, and long-term maintenance costs. This study's goal is to assess the feasibility of identifying the lowest fundamental natural frequencies of buildings without knowing the orientations and precise locations of the crowds' smartphones in advance. Both input-output and output-only identification methods are used to identify the lowest fundamental natural frequencies of numerical finite element models of a real building structure. The effects of time synchronization and the orientation alignment between nearby smartphones on the identification results are discussed, and the proposed approach's performance is verified using large-scale shake table tests of a scaled steel building. The presented results illustrate the potential of using crowdsourced smartphone data with the proposed approach to identify the lowest fundamental natural frequencies of building structures, information that should be valuable in making emergency response decisions.

The commercial application of silicon (Si) anodes with high theoretical capacity is hampered by the poorcyclic stability because the huge volume change of Si during discharge/charge processes results in thepulverization of electrode materials and the electric contact loss of electrode materials with copper(Cu) foils. Binders play an important role for adhering active materials and conductive additives togetheronto Cu foils. Herein, we design and develop a three-dimensional networked composite binder (PAA-co-SN) via an amidation reaction between polyacrylic acid (PAA) and thiourea (SN). The granular anchors(CuxS) are constructed at the interface between PAA-co-SN binders and Cu foils, resulting from the reactionof S and Cu during the drying processes of Si electrodes. When used as binders for Si nanoparticles,they exhibit stable cyclic performance (1580 mAh g1 after 500 cycles). The anchoring mechanismbetween composite binders and Cu foils provides a strategy for the improvement of electrochemicalproperties of Si-based anodes for lithium-ion batteries.

Newcastle disease virus (NDV) and Salmonella Pullorum have significant damaging effects on the poultry industry, but no previous vaccinecan protect poultry effectively. In this study, a recombinant-attenuated S. Pullorum strain secreting the NDV hemagglutinin-neuraminidase(HN) protein, C79-13ΔcrpΔasd (pYA-HN), was constructed by using the suicide plasmid pREasd-mediated bacteria homologousrecombination method to form a new bivalent vaccine candidate against Newcastle disease (ND) and S. Pullorum disease (PD). The effectof this vaccine candidate was compared with those of the NDV LaSota and C79-13ΔcrpΔasd (pYA) strains. The serum hemagglutinationinhibition antibody titers, serum immunoglobulin G (IgG) antibodies, secretory IgA, and stimulation index in lymphocyte proliferation wereincreased significantly more (p < 0.01) in chickens inoculated with C79-13ΔcrpΔasd (pYA-HN) than with C79-13ΔcrpΔasd (pYA) but werenot significantly increased compared with the chickens immunized with the LaSota live vaccine (p > 0.05). Moreover, the novel strain provides60% and 80% protective efficacy against the NDV virulent strain F48E9 and the S. Pullorum virulent strain C79-13. In summary, in this study,a recombinant-attenuated S. Pullorum strain secreting NDV HN protein was constructed. The generation of the S. Pullorum C79-13ΔcrpΔasd(pYA-HN) strain provides a foundation for the development of an effective living-vector double vaccine against ND and PD.

The phytophagous mite is highly polyphagous and widespread in warmer regions and greenhouses around the world, and so the focus of novel acaricides is shifting towards more effective, ecofriendly new chemical entity with unique modes of action. In this study, eighteen spirobutyrolactones derived from natural tetronic acid have been synthesized and their acaricidal activities against Tetranychus cinnabarinus were investigated by slide-dip method. The results of preliminary bioassay indicate that some of these compounds exhibited promising acaricidal activities, especially, compounds 6 and 18 show significant activities against T. cinnabarinus than the commercial spirodiclofen 1 (27.37% mortality), and which present 58.55% and 82.24% mortality at tested dose, respectively. The relationship between structure and acaricidal activity was also discussed based on the experimental data, and which indicate that the compounds (16, 17 and 18) with non-substituted phenyl ring (R1=H) show obviously better activities. Especially, we also can find that substituted benzoyl unit will help to increase the activity than substituted phenylacetyl group.
Use of High-performance Graphics Processing Units for Power System Demand Forecasting
Ting He,Ke Meng,ZhaoYang Dong,Yong-Taek Oh,Yan Xu 대한전기학회 2010 Journal of Electrical Engineering & Technology Vol.5 No.3
Load forecasting has always been essential to the operation and planning of power systems in deregulated electricity markets. Various methods have been proposed for load forecasting, and the neural network is one of the most widely accepted and used techniques. However, to obtain more accurate results, more information is needed as input variables, resulting in huge computational costs in the learning process. In this paper, to reduce training time in multi-layer perceptron-based short-term load forecasting, a graphics processing unit (GPU)-based computing method is introduced. The proposed approach is tested using the Korea electricity market historical demand data set. Results show that GPU-based computing greatly reduces computational costs.

Neighborhood systems present a general model for the theory of granular computing. Consistent functions can be used to study the communication between neighborhood systems. In this paper, we propose the extended notions of system consistent (sys-consistent) functions and granule consistent (gra-consistent) functions for fuzzifying neighborhood systems. The definition of the transformation of a fuzzifying neighborhood system by a mapping is presented. Then, the structure preservation properties for interior and closure operators of fuzzifying neighborhood systems are investigated.

Caveolin-1 of the caveolin family of proteins regulates mammary gland development and has been shown to play a contradictory role in breast tumor progression. A specific anti-Caveolin-1 antibody will be useful for functional study of Caveolin-1 in different tissues. In this study, we generated a rabbit polyclonal antibody that specifically recognizes the N-terminal amino acids 50-65 of Caveolin-1. This polyclonal antibody specifically reacted with Caveolin-1 extracted from cells of different species, including human epithelial A431 cells, goat primary mammary epithelial cells and mice fibroblast NIH 3T3 cells, by Western blotting. Endogenous Caveolin-1 protein expressing in cells and normal human tissues was detected by this polyclonal antibody using immunocytofluorescent and immunohistochemical staining, respectively. Furthermore, an apparent decrease in Caveolin-1 expression in tumorous breast and colon tissues was detected by this polyclonal antibody. In conclusion, we have identified amino acids 50-65 of Caveolin-1, which contains an epitope that is specific to Caveolin-1 and is conserved in the human, goat and mouse. In future, this anti-Caveolin-1 antibody can be used to examine the progression of breast and colon cancers and to study functions of Caveolin-1 in human, goat and mouse cells.
