NEWS‐GENERATED DEPENDENCE AND OPTIMAL PORTFOLIOS FOR n STOCKS IN A MARKET OF BARNDORFF‐NIELSEN AND SHEPHARD TYPE

We consider Merton's portfolio optimization problem in a Black and Scholes market with non‐Gaussian stochastic volatility of Ornstein–Uhlenbeck type. The investor can trade in n stocks and a risk‐free bond. We assume that the dependence between stocks lies in that they partly share the Ornstein–Uhlenbeck processes of the volatility. We refer to these as news processes, and interpret this as that dependence between stocks lies solely in their reactions to the same news. The model is primarily intended for assets that are dependent, but not too dependent, such as stocks from different branches of industry. We show that this dependence generates covariance, and give statistical methods for both the fitting and verification of the model to data. Using dynamic programming, we derive and verify explicit trading strategies and Feynman–Kac representations of the value function for power utility.
BANDWIDTH ENHANCEMENT TECHNIQUES COMPARISON FOR ULTRA WIDEBAND MICROSTRIP ANTENNAS FOR WIRELESS APPLICATION

Since the release by the Federal Communications Commission (FCC) of a bandwidth of 7.5GHz (from 3.1GHz to 10.6GHz) for ultra-wideband (UWB) wireless communications, UWB is rapidly advancing as a high data rate wireless communication technology. As is the case in conventional wireless communication systems, an antenna also plays a very crucial role in UWB systems. However, there are more challenges in designing a UWB antenna than a narrow band one. A suitable UWB antenna should be capable of operating over an ultra-wide bandwidth as allocated by the FCC. At the same time, satisfactory radiation properties over the entire frequency range are also necessary. To choose an optimum antenna topology for ultra wideband (UWB) design, several factors must be taken into account including physical profile, compatibility, impedance bandwidth, radiation efficiency, and radiation pattern. The main challenge in UWB antenna design is achieving the very broad bandwidth with high radiation efficiency and small in size. Accordingly, many techniques to broaden the impedance bandwidth of small antennas and to optimize the characteristics of broadband antennas have been widely investigated in many published papers as listed in this article. Planar monopole antennas are good candidates owing to their wide impedance bandwidth, omni-directional radiation pattern, compact and simple structure, low cost and ease of construction. Further detail on various bandwidth enhancement techniques will be discussed in this paper. This paper focuses on UWB planar printed circuit board (PCB) antenna design and analysis. Extensive investigations are carried out on the development of UWB antennas from the past to present. First, the planar PCB antenna designs for UWB system is introduced and described. Next, the special design considerations for UWB antennas are summarized. State-of-the-art UWB antennas are also reviewed. Finally, a new concept (case studies) for the design of a UWB antenna with a bandwidth ranging from 3GHz-8GHz is introduced, which satisfies the system requirements for S-DMB, WiBro, WLAN, CMMB and the entire UWB .

The Optimal Choice by Resource Consumers in Grid Market

Market mechanism is effective to encourage more people to participate in the Grid environment. Applying economic principles to Grid is deemed promising to improve the overall value provided by such participants. However, resource scheduling algorithms are different depending on different needs. In this paper, we mainly focus on the consumers' own interest. Assuming that the consumers are selfish and what they concern about is lower cost and higher success rate, we improve the HRED algorithm using hierarchical mechanism and resource selection mechanism, which cooperate with resource providers' trust degree, making it more suitable, practical and credible for Grid market. The experiments prove that the improved HRED algorithm works faster especially when there are large numbers of resource providers in Grid market, and it also gives much higher success rates in the non-credible Grid environment.
The pro region N-terminal domain provides specific interactions required for catalysis of alpha-lytic protease folding.

The extracellular bacterial protease, alpha-lytic protease (alphaLP), is synthesized with a large, two-domain pro region (Pro) that catalyzes the folding of the protease to its native conformation. In the absence of its Pro folding catalyst, alphaLP encounters a very large folding barrier (DeltaG = 30 kcal mol(-1)) that effectively prevents the protease from folding (t(1/2) of folding = 1800 years). Although homology data, mutational studies, and structural analysis of the Pro.alphaLP complex suggested that the Pro C-terminal domain (Pro C-domain) serves as the minimum "foldase" unit responsible for folding catalysis, we find that the Pro N-terminal domain (Pro N-domain) is absolutely required for alphaLP folding. Detailed kinetic analysis of Pro N-domain point mutants and a complete N-domain deletion reveal that the Pro N-domain both provides direct interactions with alphaLP that stabilize the folding transition state and confers stability to the Pro C-domain. The Pro N- and C-domains make conflicting demands upon native alphaLP binding that are alleviated in the optimized interface of the folding transition state complex. From these studies, it appears that the extremely high alphaLP folding barrier necessitates the presence of both the Pro domains; however, alphaLP homologues with less demanding folding barriers may not require both domains, thus possibly explaining the wide variation in the pro region size of related pro-proteases.
BCAR1, a human homologue of the adapter protein p130Cas, and antiestrogen resistance in breast cancer cells.

BACKGROUND Treatment of breast cancer with the antiestrogen tamoxifen is effective in approximately one half of the patients with estrogen receptor-positive disease, but tumors recur frequently because of the development of metastases that are resistant to tamoxifen. We have previously shown that mutagenesis of human estrogen-dependent ZR-75-1 breast cancer cells by insertion of a defective retrovirus genome caused the cells to become antiestrogen resistant. In this study, we isolated and characterized the crucial gene at the breast cancer antiestrogen resistance 1 (BCAR1) locus. METHODS/RESULTS Transfer of the BCAR1 locus from retrovirus-mutated, antiestrogen-resistant cells to estrogen-dependent ZR-75-1 cells by cell fusion conferred an antiestrogen-resistant phenotype on the recipient cells. The complete coding sequence of BCAR1 was isolated by use of exon-trapping and complementary DNA (cDNA) library screening. Sequence analysis of human BCAR1 cDNA predicted a protein of 870 amino acids that was strongly homologous to rat p130Cas-adapter protein. Genomic analysis revealed that BCAR1 consists of seven exons and is located at chromosome 16q23.1. BCAR1 transcripts were detected in multiple human tissues and were similar in size to transcripts produced by retrovirus-mutated ZR-75-1 cells. Transfection of BCAR1 cDNA into ZR-75-1 cells again resulted in sustained cell proliferation in the presence of antiestrogens, confirming that BCAR1 was the responsible gene in the locus. CONCLUSIONS Overexpression of the BCAR1 gene confers antiestrogen resistance on human ZR-75-1 breast cancer cells. Overexpression of BCAR1 in retrovirus-mutated cells appears to result from activation of the gene's promoter. The isolation and characterization of this gene open new avenues to elucidating mechanisms by which the growth of human breast cancer becomes independent of estrogen.
A Smart Gateway for Health Care System Using Wireless Sensor Network

Using Wireless Sensor Networks (WSNs) in health care system has yielded a tremendous effort in recent years. However, in most of these researches, tasks like sensor data processing, health state decisions making and emergency messages sending are completed by a remote server. Transmitting and handing with a large scale of data from body sensors and home sensors consume a lot of communication resource, bring a burden to the remote server and delay the decision time and notification time. In this paper, we present a prototype of a smart gateway that we have implemented. This gateway is an interconnection and services management platform especially for WSN health care systems at home environment. By building a bridge between a WSN and public communication networks, and being compatible with an on-board data decision system and a lightweight database, our smart gateway system is enabled to make patients' health state decisions in low-power and low-cost embedded system and get faster response time o the emergencies. We have also designed the communication protocols between WSN, gateway and remote servers. Additionally Ethernet, Wi-Fi and GSM/GPRS communication module are integrated into the smart gateway in order to report and notify information to care-givers. We have conducted experiments on the proposed smart gateway by performing it together with a wireless home e-health care sensor network. The results show that the smart gateway design is feasible and has low latency.

Effect of Cu Content on Atomic Positions of Ti50Ni50−xCux Shape Memory Alloys Based on Density Functional Theory Calculations

The study of crystal structures in shape memory alloys is of fundamental importance for understanding the shape memory effect. In order to investigate the mechanism of how Cu content affects martensite crystal structures of TiNiCu alloys, the present research examines the atomic displacement of Ti50Ni50−xCux (x = 0, 5, 12.5, 15, 18.75, 20, 25) shape memory alloys using density functional theory (DFT). By the introduction of Cu atoms into TiNi martensite crystal to replace Ni, the displacements of Ti and Ni/Cu atoms along the x-axis are obvious, but they are minimal along the y- and z-axes. It is found that along the x-axis, the two Ti atoms in the unit cell move in opposite directions, and the same occurred with the two Ni/Cu atoms. With increasing Cu content, the distance between the two Ni/Cu atoms increases while the Ti atoms draw closer along the x-axis, leading to a rotation of the (100) plane, which is responsible for the decrease in the monoclinic angle. It is also found that the displacements of both Ti atoms and Ni/Cu atoms along the x-axis are progressive, which results in a gradual change of monoclinic angle and a transition to B19 martensite crystal structure.
Interpreting and Extending an Analytical Battery Model Using an Iterative Computation Method

In this paper, the authors present an iterative computing method to illustrate the discharge, recovery and charge process of general lithium/lithium-ion batteries. The discharge and recovery processes correspond well to an existing accurate analytical battery model: the R-V-W's analytical model, and thus interpret this model algorithmically. Our method also extends R-V-W's model to accommodate the charge process. The work will help the system designers to grasp the characteristics of R-V-W's battery model. Experiments are performed on a variety of load profiles to show the accuracy of the extended model by comparing the predicted charge time with that derived from the DUALFOIL simulations
Proactively controlling round-trip time variation and packet drops using SmoothTCP-q

Packet drops are the primary means of signalling congestion in TCP. However, packet drops have a great impact on round-trip time (RTT) variation of TCP applications. A different and more proactive approach is used by SmoothTCP-q, where ICMP-SQ messages are sent directly to the sender every time a threshold is reached in the queue size of the router. In this mechanism, SmoothTCP-q tries to avoid packet drops since it is not necessary to overload the router queue to discover the network bandwidth as Standard TCP does. As a result, SmoothTCP-q generally presents better quality of service characteristics in terms of RTT variation and packet drops when compared to TCP. In this paper we describe SmoothTCP-q and illustrate its main characteristics related to this proactive property.
Biogeosciences Towards the use of dynamic growing seasons in a chemical transport model

Chemical transport models (CTMs), used for the prediction of, for example, nitrogen deposition or air quality changes, require estimates of the growing season of plants for a number of reasons. Typically, the growing seasons are defined in a very simplified way in CTMs, using fixed dates or simple functions. In order to explore the importance of more realistic growing season estimates, we have developed a new and simple method (the T5 method) for calculating the start of the growing season (SGS) of birch (which we use as a surrogate for deciduous trees), suitable for use in CTMs and other modelling systems. We developed the T5 method from observations, and here we compare with these and other methodologies, and show that with just two parameters T5 captures well the spatial variation in SGS across Europe. We use the EMEP MSC-W chemical transport model to illustrate the importance of improved SGS estimates for ozone and two metrics associated with ozone damage to vegetation. This study shows that although inclusion of more realistic growing seasons has only small effects on annual average concentrations of pollutants such as ozone, the metrics associated with vegetation risk from ozone are significantly affected. This work demonstrates a strong need to include more realistic treatments of growing seasons in CTMs. The method used here could also be suitable for other types of models that require information on vegetation cover, such as meteorological and regional climate models. In future work, the T5 and other methods will be further evaluated for other forest species, as well as for agricultural and grassland land covers, which are important for emissions and deposition of reactive nitrogen compounds.
Comparison of Soil Nitrogen Tests for Corn Fertilizer Recommendations in the Humid Southeastern USA

Environmental concerns about increasing NO 3 levels in watersheds in North Carolina and elsewhere indicate the need for better N fertilizer management. Nitrate levels might be reduced if N rates could be adjusted based on field- or site-specific knowledge of corn (Zea mays L.) response to N fertilization. Currently, there is no effective soil N test for the humid southeastern USA. This study was conducted to compare three soil N tests for practicality, precision, and ability to correlate with economic optimum N rate (EONR) and fertilizer response on southeastern U.S. soils. The soil N tests were the Illinois soil N test (ISNT), the gas pressure test (GPT), and the incubation and residual N test (IRNT). Soil samples were collected from the sites of 16 N-response trials from 2001 to 2003 where different mineralizable and residual N levels were expected. The ISNT was determined to be the most practical test because it was the easiest to perform and could be completed in 1 d. The ISNT and GPT had better precision (lower CV) than the IRNT (9 and 13 vs. 61%, respectively). All three tests were related to EONR; ISNT had the strongest linear relationship (r 2 = 0.90) when consideration was restricted to sites on mineral soils. The ISNT and GPT were related to delta yield (maximum yield minus check yield; r 2 = 0.49 and 0.60, respectively) and fertilizer response (r 2 = 0.31 and 0.51, respectively). These results indicate the potential of the ISNT and GPT to account for mineralizable and residual soil N levels and thus improve current corn N recommendations in the humid southeastern USA.
NSOM: A Tool To Detect Denial Of Service Attacks Using Self-Organizing Maps

An implementation of a network based Intrusion Detection System using a SelfOrganizing Map (SOM) as a clustering tool is described. The system uses a SOM to classify Ethernet data in real-time. A graphical tool constantly displays the clustered data to reflect network activities. The impact of using different techniques for data collection, data preprocessing and classifier design is discussed. The system shows promise in its ability to classify regular traffic verses irregular traffic as a result of a Denial of Service (DoS) attack on a given host.
Exploring similarity among Web pages using the hyperlink structure

Hyperlinks inside HTML pages contain a wealth of information about the relationships among Web pages. Given a set of Web pages, we can explore the hyperlink relationships among these pages. This paper first provides formal definitions of hyperlink relations. We then use the notations to define similarity between two Web pages and between two sets of Web pages. For each one of them, we provide several definitions of similarity using forward and backward links. The similarity measure gives us a number between 0 and 1. We also demonstrate how to use the similarity measure to study clustering within a set of pages and to determine the "diversity" of a set of Web pages.
Multidimensional Fast Multiplierless DCT Algorithm Using Ramanujan Ordered Numbers

—This paper proposes a new multidimensional (m-D) multiplierless Ramanujan Numbered Discrete Cosine Transform (RDCT) based coding to improvise the coding efficiency in the visual data compression for multimedia applications. In this paper, the mD-DCT with size 12 m N N N   , where i N power of 2 is, can be converted into a series of one dimensional (1-D) DCT's which are evaluated using Ramanujan Ordered Numbers thereby making the algorithm multiplierless. The proposed algorithm achieves considerable savings in terms of shift operations compared with the row-column approach thus making it suitable for image and video coding applications. For a 3-dimensional input data of size 888 , the algorithm reduces the number of shift operations by 66% compared to multidimensional row-column approach and approximately 0.1% increase in the number of adders compared with the row-column approach. Compared with the other recently presented multidimensional DCT algorithms, the proposed one gives better result as it uses the shift operations instead of the floating-point multipliers and also achieves considerable reduction in the number of addition operation .
Interactive Compromise Approach with Particle Swarm Optimization for Environmental/Economic Power Dispatch

In this paper, an Interactive Compromise Approach with Particle Swarm Optimization(ICA-PSO) is presented to solve the Economic Emission Dispatch(EED) problem. The cost function and emission function are modeled as the nonsmooth functions, respectively. The bi-objective including both the minimization of cost and emission is formulated in this paper. ICA-PSO is proposed to solve EED problem for finding a better compromise solution. The solution methodology can offer a global or near-global solution for decision-making requirements. The effectiveness and efficiency of ICA-PSO are demonstrated by a sample test system. Test results can be shown that the proposed method provide a practical and flexible framework for power dispatch. Keywords—Interactive Compromise Approach, Emission Control, Economic Dispatch, Particle Swarm Optimization.
ProDFA: Accelerating Domain Applications with a Coarse-Grained Runtime Reconfigurable Architecture

With the on-chip resources largely increased, modern architectures are much different from traditional ones. The relation between temporal computing and spatial computing is getting more and more intricate. In this paper, we first analyzed and compared the abstract computing models of modern architectures. Then, a runtime reconfigurable architecture called programmable dataflow computing architecture (ProDFA) is proposed. The architecture of ProDFA is sumarized, then the process of how applications are mapped and execute are simply introduced. As a case study, a specific reconfigurable structure for symmetric ciphers is implemented. Performance of several typical symmetric ciphers are evaluated. The experimental results show high performance and efficiency of ProDFA.
Local Change in Urinary Bladder Contractility Following CNS Dopamine Denervation in the 6-OHDA Rat Model of Parkinson’s Disease

Abstract Background: Urinary problems, including urinary frequency, urgency, and nocturia are some of the non-motor symptoms that correlate most with poor quality of life in Parkinson’s disease. However, the mechanism behind these symptoms is poorly understood, in particular regarding peripheral bladder pathophysiology following dopamine degeneration. Objective: In this study, we compared the contractile responsiveness of urinary bladder from the 6-OHDA unilateral rat model of Parkinson’s disease with that of normal untreated animals. Methods: The contractility of the urinary detrusor muscle was evaluated in bladder strip preparations using electrical field stimulation, and muscarinic and purinoceptor stimulations in an vitro organ bath setup. Results: Our data show that the overall contractile response following electrical field stimulation was significantly higher (43% at maximum contraction by 20–40 Hz stimulation) in the 6-OHDA-lesioned rats as compared to control animals. This increase was associated with a significant increase in the cholinergic contractile response, where the muscarinic agonist methacholine produced a 44% (at 10 −4 M concentration) higher response in the 6-OHDA-treated rats as compared to controls with a significant left-shift of the dose response. This indicates an altered sensitivity of the muscarinic receptor system following the specific central 6-OHDA-induced dopamine depletion. In addition a 36% larger contraction of strips from the 6-OHDA animals was also observed with purinoceptor activation using the agonist ATP (5×10 −3 M) during atropine treatment. Conclusions: Our data shows that it is not only the central dopamine control of the micturition reflex that is altered in Parkinson’s disease, but also the local contractile function of the urinary bladder. The current study draws attention to a mechanism of urinary dysfunction in Parkinson’s disease that has previously not been described.
