Growing radial basis function network models

In this paper a learning algorithm for creating a Growing Radial Basis Function Network (RBFN) Model is presented and analyzed. The main concept of this algorithm is that the number of the Radial Basis Function (RBF) units is gradually increased at each learning step of the algorithm and the model is gradually improved, until a predetermined (desired) approximation error is achieved. The important point here is that at each step of increasing the number of the RBF units, an optimization algorithm is run to optimize the parameters of only this unit, while keeping the parameters of all the previously optimized RBF units. Such strategy, even if being suboptimal, leads to significant reduction in the number of the parameters that have to be optimized at each step. A modified constraint version of the particle swarm optimization (PSO) algorithm with inertia weight is develop and used in this paper. It allows for obtaining optimal solutions with clear practical meaning. A synthetic nonlinear test example is used in the paper to analyze the performance of the proposed learning algorithm for creating the Growing RBFN model. A comparison with the standard algorithm for simultaneous optimization of all parameters of the classical RBFN model with fixed number of units is also done. It shows that the learning of the Growing RBFN model leads to a more stable and in many cases more accurate solution.
Impacts and Benefits of MICE Tourism: A Framework for Analysis

The Meetings, Incentives, Conventions and Exhibitions (MICE) sector of tourism is rapidly expanding worldwide. This paper discusses some neglected issues relating to the assessment of the narrower economic impacts, the economy-wide impacts and the net benefits of an expanding MICE sector within a tourism destination. The paper does not attempt to provide estimates of impacts or net national benefits as such, bur attempts to enhance our understanding of issues important to the subsequent task of assessment and thus to more informed policy making in this area.
Inhibition of Human Peptidyl Dipeptidase (Angiotensin I Converting Enzyme: Kininase II) by Human Serum Albumin and its Fragments

SUMMARY Purified peptidyl dipeptidase (angiotensln I converting enzyme or kininase II) from human lung or hog kidney is inhibited by commercially prepared plasma protein preparations, by human serum albumin and by the additive albumin stabilizer, acetyltryptophan. After the initial steps of purification, albumin was detected by iramunodiffusion as a component in human lung peptidyl dipeptidase preparation. Fragment C of albumin (sequence 124-298) is a more potent inhibitor than the parent molecule (K, = 1.7 X 10 8 M). Reduction and carboxymethylation of five of the six S-S bridges in Fragment C yield the most potent noncompetitive inhibitor (K, = 3 X 10 ' M). Reduction of the sixth bridge raises the K,. This indicates that maintenance of the tertiary structure in Fragment C is of importance for the inhibition. Neither albumin nor Fragment C are substrates of the enzyme. Fragment C and its derivative also inhibit the inactivation of bradykinin by the purified human enzyme and by the peptidyl dipeptidase on the surface of intact cultured human endotbeliai cells.
On a Tractable Small Open Economy Model with Endogenous Monetary-policy Trade-offs F

We propose a new highly tractable small open economy model with incomplete financial markets. The key aspect of the model is that it is not isomorphic to a closed economy, as has been shown in similarly tractable small open economy models. Under incomplete markets the real exchange rate is a fundamental variable in determining the equilibrium. This exchange rate channel introduces an endogenous trade-off for monetary policy. We also show that the welfare consistent monetary-policy loss function includes the real exchange rate as an argument, reflecting the endogenous monetary-policy trade-off. JEL CODES: E52; F41

Petroleum Ether Extract of Cissus Quadrangularis (Linn.) Enhances Bone Marrow Mesenchymal Stem Cell Proliferation and Facilitates Osteoblastogenesis

OBJECTIVE To evaluate the effects of the petroleum ether extract of Cissus quadrangularis on the proliferation rate of bone marrow mesenchymal stem cells, the differentiation of marrow mesenchymal stem cells into osteoblasts (osteoblastogenesis) and extracellular matrix calcification. This study also aimed to determine the additive effect of osteogenic media and Cissus quadrangularis on proliferation, differentiation and calcification. METHODS MSCs were cultured in media with or without Cissus quadrangularis for 4 weeks and were then stained for alkaline phosphatase. Extracellular matrix calcification was confirmed by Von Kossa staining. marrow mesenchymal stem cells cultures in control media and osteogenic media supplemented with Cissus quadrangularis extract (100, 200, 300 μg/mL) were also subjected to a cell proliferation assay (MTT). RESULTS Treatment with 100, 200 or 300 μg/mL petroleum ether extract of Cissus quadrangularis enhanced the differentiation of marrow mesenchymal stem cells into ALP-positive osteoblasts and increased extracellular matrix calcification. Treatment with 300 μg/mL petroleum ether extract of Cissus quadrangularis also enhanced the proliferation rate of the marrow mesenchymal stem cells. Cells grown in osteogenic media containing Cissus quadrangularis exhibited higher proliferation, differentiation and calcification rates than did control cells. CONCLUSION The results suggest that Cissus quadrangularis stimulates osteoblastogenesis and can be used as preventive/ alternative natural medicine for bone diseases such as osteoporosis.

Notice of RetractionAdaptive time-stepping particle fluid motion simulation

An adaptive time-step approach is proposed to perform real-time particle fluid simulation. In traditional adaptive approaches, the iterative process of each element updating is limited to the minimum and fixed time step, which results in the computational resources wasting. This paper solved such a problem by adjusting the element updating periodicity with its reachable time step. And a common Distance Fields method is presented to transform arbitrary meshes and particle models for fluid modeling and rigid body modeling, which provides the basis for interaction of fluid. Experiments proved the proposed method feasible and efficiency.

Relevant Factors of Estrogen Changes of Myopia in Adolescent Females

Background: Gender is one of the risk factors accounting for the high prevalence of adolescent myopia. Considerable research results have shown that myopia incidence of female is higher than that of male. This study aimed to analyze the correlation between ocular parameters and serum estrogen level and to investigate the vision changes along with estrogen change in menstrual cycle of adolescent females. Methods: A total of 120 young females aged between 15 and 16 years, diagnosed with myopia were recruited. Spherical lens, cylindrical lens, axis, interpupillary distance (IPD), and vision in each tested eye of the same subject were measured by automatic optometry and comprehensive optometry, with repetition of all measurements in the menstrual cycle of the 2nd or 3rd days, 14th days, and 28th days, respectively. Serum estradiol (E2) levels were assayed by chemiluminescence immunoassay at the same three times points of the menstrual cycle mentioned above. Results: In young females with myopia, the spherical lens showed a statistically significant difference among all different time in menstrual cycle (all P < 0.0001). The cylindrical lens, axis, and IPD were changed significantly during the menstrual cycle (P < 0.05). The vision of the three different time points in menstrual cycle had a significant difference (&khgr;2 = 6.35, P = 0.042). The vision during the 14th and 28th day was higher compared to that on the 2nd or 3rd days (P = 0.021). Serum E2 levels were significantly different at different time points in menstrual cycle (P < 0.05). E2 levels reached its maximum value on the 14th day and the minimum value on the 2nd or 3rd day. Conclusions: In adolescent females, the spherical lens and other related ocular parameters vary sensitively with different levels of E2 in menstrual cycle. Vision in late menstrual stage is significantly higher than that in premenstrual stage.
An Insecticidal Compound Produced by an Insect-Pathogenic Bacterium Suppresses Host Defenses through Phenoloxidase Inhibition

A bioassay-guided column chromatographic strategy was adopted in the present study to fractionate the culture extract of Photorhabdus temperata M1021 to identify potential insecticidal and antimicrobial compounds. An ethyl acetate (EtOAc) culture extract of P. temperata was assayed against Galleria mellonella larvae through intra-hemocoel injection and exhibited 100% insect mortality within 60 h. The EtOAc fraction and an isolated compound exhibited phenoloxidase (PO) inhibition of up to 60% and 63%, respectively. The compound was identified as 1,2-benzenedicarboxylic acid (phthalic acid, PA) by gas chromatography-mass spectrometry and nuclear magnetic resonance. PA exhibited insecticidal activity against G. mellonella in a dose-dependent manner, and 100% insect mortality was observed at 108 h after injection of 1 M PA. In a PO inhibition assay, 0.5 and 1 M concentrations of PA were found to inhibit PO activity by 74% and 82%, respectively; and in a melanotic nodule formation assay, nodule formation was significantly inhibited (27 and 10 nodules) by PA (0.5 and 1 M, respectively). PA was furthermore found to have substantial antioxidant activity and maximum antioxidant activity was 64.7% for 0.5 M PA as compare to control. Antibacterial activity was assessed by The MIC values ranged from 0.1 M to 0.5 M of PA. This study reports a multifunctional PA, a potential insecticidal agent, could a factor of insect mortality along with other toxins produced by P. temperata M1021.
An association study between genetic polymorphisms related to lipoprotein-associated phospholipase A2 and coronary heart disease

Previous genome-wide association studies (GWAS) have revealed seven single nucleotide polymorphisms (SNPs) that affect lipoprotein-associated phospholipase A2 (Lp-PLA2) activity or levels in American and European individuals. A total of 290 coronary heart disease (CHD) patients, 198 non-CHD patients and 331 unrelated healthy volunteers were recruited for the present case-control study of Han Chinese. Four SNPs (rs964184 of ZNF259, rs7528419 of CELSR2 and rs7756935 and rs1805017 of PLA2G7) were shown to be significantly associated with CHD. The rs964184-G allele of the ZNF259 gene was identified as a risk factor of CHD in females (odds ratio (OR) =1.49, 95% confidence interval (CI) =1.00–2.22, P=0.05). The rs7528419-G allele of the CELSR2 gene was protective against CHD in males (OR=0.48, 95% CI=0.25–0.93, P=0.04). The other two alleles (rs7756935-C and rs1805017-A) of the PLA2G7 gene acted as protective factors against CHD in females (rs7756935-C: OR=0.59, 95% CI=0.35–1.00, P=0.05; rs1805017-A: OR=0.51, 95% CI=0.28–0.93, P=0.03). Moreover, rs1805017 of the PLA2G7 gene was associated with the severity of CHD only in females (r2=0.02, P=0.04). We identified four Lp-PLA2-associated SNPs significantly associated with CHD in a Han Chinese population. Specifically, rs7528419 was protective factor against CHD in males, while the other two SNPs (rs7756935 and rs1805017 of the PLA2G7 gene) were protective factors against CHD in females and rs964184 of the ZNF259 gene was regarded as a risk factor for CHD in females.
An Efficient Resource Reservation and QoS Provisioning Mechanism Based on mSCTP for Next Generation Network

The next generation network (NGN) must provide mobility and multiple interfaces to enable the seamless delivery of packets, in IP mobility environments, with the best possible quality of service (QoS) guarantee. This paper proposes an efficient resource reservation and QoS provisioning mechanism based on mobile SCTP (mSCTP) with network mobility and multi-homing for NGN. To do this, the proposed mechanism does not refresh the reserved resources on the common path through the path management at the time of mSCTP-based handover. The path management is accomplished by maintaining the common path and common routers on the path. To show the validity of the proposed mechanisms, the ns-2 simulator was used, it can provide the end-to-end seamless QoS and resources management in IP mobility environments more efficiently.
A fast alignment algorithm based on inertial frame for marine SINS

A fast alignment algorithm based on inertial frame is proposed in this paper. Firstly, a third-order leveling loop is used for fine leveling alignment to establish a level coordinate frame. Secondly, the property that the projection of the gravitational vector in level coordinate frame is unrelated to heading angle is used to calculate the projection of the gravitational vector in body inertial coordinate frame. Thirdly, the projection of the gravitational vector is smoothed through weighted average algorithm, so that the fast alignment based on inertial frame is completed. Finally, the simulation and mooring test validate the speedability and accuracy of this fast alignment algorithm. The results show that the fast initial alignment algorithm can achieve the medium accuracy in 6 minutes. It fulfills the accuracy requirement for the medium accuracy marine SINS.
Improving TCP Performance Using Cross-Layer Feedback in Wireless LANs

Currently, more and more research work has been done for the optimization of TCP performance in wireless networks. The majority of these schemes proposed are trying to optimize the system within the single layer. Obviously, jointly considering the interaction between transport layer and other layers, it may bring the improvement for TCP performance. In this paper, we propose a novel approach using cross-layer ARQ feedback (CLF-TCP) to enhance the performance of TCP in wireless LANs. Its basic idea is cross-three-layer optimization for TCP performance by utilizing the HARQ acknowledgment in PHY-layer as the ARQ acknowledgment in MAC-layer implicitly while exploiting the information of ARQ in MAC-layer for more efficient acknowledgement for TCP segment delivery. Simulation results show that the scheme CLF-TCP not only decrease the overhead for ARQ feedback and the average transmission delay, but also improve TCP throughput effectively.

Elsevier Editorial System(tm) for Image and Vision Computing Title: Non-rigid Face Tracking with Enforced Convexity and Local Appearance Consistency Title:-non-rigid Face Tracking with Enforced Convexity and Local Appearance Consistency Constraint Non-rigid Face Tracking with Enforced Convexity and 

Convex quadratic fitting (CQF) has demonstrated great success recently in the task of non-rigidly registering a face in a still image using a constrained local model (CLM). A CLM is a commonly used model for non-rigid object registration and contains two components: (i) local patch-experts that model the appearance of each landmark in the object, and (ii) a global shape prior describing how each of these landmarks can vary non-rigidly. Conventional CLMs can be used in non-rigid facial tracking applications through a track-by-detection strategy. However, the registration performance of such a strategy is susceptible to local appearance ambiguity. Since there is no motion continuity constraint between neighboring frames of the same sequence, the resultant object alignment might not be consistent from frame to frame and the motion field is not temporally smooth. In this paper, we extend the CQF fitting method into the spatio-temporal domain by enforcing the appearance consistency constraint of each local patch between neighboring frames. More importantly, we show, as in the original CQF formulation, that the global warp update can be optimized jointly in an efficient manner. Finally, we demonstrate that our approach receives improved performance for the task of non-rigid facial motion tracking on the videos of clinical patients.

A Rewriting System for the Construction of Small Finite Automata from Regular Expressions

We present a linear-time construction of normalized nondet erministic finite automata with ε-transitions from regular expressions. This is realized by rewriting digraphs that are labeled with regular expressions. The size of the constr ucted automata is shown to be within 22 15 times the size of the input expressions. A family of expressi on that reaches this value is inferred constructively, and the automata pro vided by our method for such expressions are shown to be minimal. This provides a tight no nasymptotic upper and lower bound for the size-ratio of corresponding regular exp r ssions and finite automata.
Prepotentials of N = 2 Supersymmetric Gauge Theories and Soliton Equations

Using recently proposed soliton equations we derive a basic identity for the scaling violation of N=2 supersymmetric gauge theories Σiai∂F/∂ai−2F=8πib1u. Here F is the prepotential, ai’s are the expectation values of the scalar fields in the vector multiplet, u=1/2 Tr and b1 is the coefficient of the one-loop β-function. This equation holds in the Coulomb branch of all N=2 supersymmetric gauge theories coupled with massless matter.
