Updating Inventories with Intelligent Agents

—This paper describes a procedure to automatically solve misalignments between inventories by means of expert agents. We apply this mechanism to maintain the repository of a (cid:31)etwork Manager System ((cid:31)MS), which allows executing different tasks over a transmission network in a Telecommunication Operator: fulfillment, supervision, etc. The consistency in the (cid:31)MS inventory is maintained by means of connections to corporate systems (repository, planning, and assignment systems) and operations over (cid:31)etwork Element Managers ((cid:31)EMs) regarding to deployment of (cid:31)etwork Equipments ((cid:31)Es) or cards, setting up of circuits, paths and physical links. This repository contains data about managed elements, Synchronous Digital Hierarchy (SDH), Ethernet and Wavelength Division Multiplexing (WDM) components, and not managed elements: Radio, Plesiochronous Digital Hierarchy (PDH), fibers, etc. Sometimes misalignments occur between the corporate inventory and the repository in (cid:31)MS. These misalignments have to be solved by the technicians. Our method incorporates the necessary intelligence to analyze failures and the mechanisms to solve them in expert agents, therefore preventing technicians from checking and solving main errors. It reduces Operating Expenditures (OPEX).
Observational goals for Max '91 to identify the causative agent for impulsive bursts

Recent studies of impulsive hard x ray and microwave bursts suggest that a propagating causative agent with a characteristic velocity of the order of 1000 km/s is responsible for these bursts. The results of these studies are summarized and observable distinguishing characteristics of the various possible agents are highlighted, with emphasis on key observational goals for the Max '91 campaigns. The most likely causative agents suggested by the evidence are shocks, thermal conduction fronts, and propagating modes of magnetic reconnection in flare plasmas. With new instrumentation planned for Max '91, high spatial resolution observations of hard x ray sources have the potential to identify the agent by revealing detailed features of source spatial evolution. Observations with the Very Large Array and other radio imaging instruments are of great importance, as well as detailed modeling of coronal loop structures to place limits on their density and temperature profiles. With the combined hard x ray and microwave imaging observations, aided by loop model results, the simplest causative agent to rule out would be the propagating modes of magnetic reconnection. To fit the observational evidence, reconnection modes would need to travel at approximately the same velocity (the Alfven velocity) in different coronal structures that vary in length by a factor of 10(exp 3). Over such a vast range in loop lengths, it is difficult to believe that the Alfven velocity is constant. Thermal conduction fronts would be suggested by sources that expand along the direction of B and exhibit relatively little particle precipitation. Particle acceleration due to shocks could produce more diverse radially expanding source geometries with precipitation at loop footprints.
Scholars' Numerical Simulation of Active Fault Rupture Prpagation Through Dry Soil

Numerical simulation of fault rupture propagation through dry soil was performed using the finite difference code FLAC. A Mohr-Coulomb elasto-plastic constitutive model with strain softening was used to simulate soil behavior. The bedrock motion, prescribed at the bottom boundary of the mesh, was based on relevant seismological theories and observations. A total of 42 parametric analyses were performed where the shear strain rate and the plastic shear strain contours were used for localizing the rupture propagation as a shear band. Parametric analyses show that results are sensitive to the assumed soil type and dilatancy angle, but not to the soil layer thickness. Furthermore, it is concluded that: 1) the declination of the fault trace from the straight projection of the fault plane is higher in dilatant soils, 2) a graben is formed in cases of normal faults with relatively shallow dip-slip angle, 3) high values of the dilatancy angle tend to decrease the width of distorted zone on the ground surface and 4) local amplification of ground motion is possible near the fault trace in dense soils, especially in reverse faulting cases.
Extremal Graphs and Additive Combinatorics

In this thesis we investigate graphs that are constructed using objects from additive number theory. Sidon sets are used to construct C₄-free graphs that show ex( q² - q - 2 , C₄) > 1/2q³ - q² - O(q³/⁴) whenever q is an odd prime power. This disproves a conjecture of Abreu, Balbuena, and Labbate and improves the current lower bound by q/2. Sidon sets are also used to show that there are bipartite graphs F for which the following holds: for infinitely many n there is an n-vertex graph with [Omega] (ex(n , F) edges and has the property that every edge lies in exactly one copy of F. This disproves a conjecture of Solymosi concerning a possible extension of the removal lemma to sparse graphs. An ordered Turan problem for bipartite graphs is introduced and studied. We prove upper bounds on this problem and use B_k-sets to obtain lower bounds. Generalizations of Sidon sets, such as k-fold Sidon sets and B_k*-sets, are studied. We prove that for any integer k > 3, if A \subset \{1,2. , N} is a B_k*-set, then IAI 3, we construct B_k-sets that have more elements than the Bose- Chowla B_k-sets. A consequence is that there are B₃-sets in {1,2. , N} that are asymptotically larger than any B₃ -set contained in {1,2. , N}. For any integer k > 3, we prove that if A \subset {1,2. , N} is a k-fold Sidon set, then IAI < ( N /k )¹/² + O( (N/k)¹/⁴). This improves the current upper bound by a factor of (1 / k)¹/²
Muscle-speciﬁc BCL2 expression ameliorates muscle disease in laminin a 2-deﬁcient, but not in dystrophin-deﬁcient, mice

To examine the role of apoptosis in neuromuscular disease progression, we have determined whether pathogenesis in dystrophin-deﬁcient ( mdx ) and laminin a 2-deﬁcient ( Lama2-null ) mice is ameliorated by overexpression of the anti-apoptosis protein BCL2 in diseased muscles. The mdx mice are a model for the human disease, Duchenne muscular dystrophy (DMD), and the Lama2-null mice are a model for human congenital muscular dystrophy type 1A (MDC1A). For these studies, we generated transgenic mice that over-expressed human BCL2 under control of muscle-speciﬁc MyoD or MRF4 promoter fragments. We then used cross-breeding to introduce the transgenes into diseased mdx or Lama2-null mice. In mdx mice, we found that overexpression of BCL2 failed to produce any signiﬁcant differences in muscle pathology. In contrast, in the Lama2-null mice, we found that muscle-speciﬁc expression of BCL2 led to a several-fold increase in lifespan and an increased growth rate. Thus, BCL2-mediated apoptosis appears to play a signiﬁcant role in pathogenesis of laminin a 2 deﬁciency, but not of dystrophin deﬁciency, suggesting that therapies designed to ameliorate disease by inhibition of apoptosis are more likely to succeed in MDC1A than in DMD.
Improved Data Access Method In Ad hoc Networks

: Mobile ad hoc network (MANET) makes it possible to dynamic changes in topology and in the availability of resources. For database integrity, Concepts of role-based access and databases are combined to specify separation of duty (on wireless networks) as required. The framework to adapt method based access control models in the MANET environment is discussed. There is an approach where a system developer can design a roll based authorization model for data access and its transfer in an ad-hoc environment.
Extensions of Lipschitz mappings into Hilbert space

(Here ll&lltip is the Lipschitz constant of the function g.) A classical result of Kirszbraun's [14, p. 48] states that L(t2, n) = 1 for all n, but it is easy to see that L(X, n) ~ ~ as n ~ ~ for many metric spaces X. Marcus and Pisier [10] initiated the study of L(X, n) for X = Lp. (For brevity, we will use hereafter the notation L(p, n) for L(Lp(O,l), n). ) They prove that for each 1 < p < 2 there is a constant C(p) so that for n = 2, 3, 4, , , ,
Study of magnetic field expansion using a plasma generator for space radiation active protection

There are many active protecting methods including Electrostatic Fields,Confined Magnetic Field,Unconfined Magnetic Field and Plasma Shielding etc.for defending the high-energy solar particle events(SPE) and Galactic Cosmic Rays(GCR) in deep space exploration.The concept of using cold plasma to expand a magnetic field is the best one of all possible methods so far.The magnetic field expansion caused by plasma can improve its protective efciency of space particles.One kind of plasma generator has been developed and installed into the cylindrical permanent magnet in the eccentric.A plasma stream is produced using a helical-shaped antenna driven by a radio-frequency(RF) power supply of 13.56 MHz,which exits from both sides of the magnet and makes the magnetic field expand on one side.The discharging belts phenomenon is similar to the Earth’s radiation belt,but the mechanism has yet to be understood.A magnetic probe is used to measure the magnetic field expansion distributions,and the results indicate that the magnetic field intensity increases under higher increments of the discharge power.
Minimax or maxisets

We discuss a new way of evaluating the performance of a statistical estimation procedure. This consists of investigating the maximal set where a given procedure has a given rate of convergence. Although the setting is not vastly different from the minimax context, it is in a sense less pessimistic and provides a functional set which is authentically connected to the procedure and the model. We also investigate more traditional concerns about procedures: oracle inequalities. Difficulties arise in the practical definition of this notion when the loss function is not the L2 norm. We explain these difficulties and suggest a new definition in the case of Lp norms and pointwise estimation. We investigate the connections between maxisets and local oracle inequalities, and prove that verifying a local oracle inequality implies that the maxiset automatically contains a prescribed set linked with the oracle inequality. We have investigated the consequences of this statement on well-known efficient adaptive methods: wavelet thresholding and local bandwidth selection. We prove local oracle inequalities for these methods and draw conclusions about the maxisets associated with them.
Institutional Knowledge at Singapore Management University Automated online news classification with personalization

Classiﬂcation of online news, in the past, has often been done manually. In our proposed Categorizor system, we have experimented an automated approach to classify online news using the Support Vector Machine (SVM). SVM has been shown to deliver good classiﬂcation results when ample training documents are given. In our research, we have applied SVM to personalized classiﬂcation of online news. In personalized classiﬂcation, users can deﬂne their personalized categories using a few keywords. By constructing search queries using these keywords, Categorizor obtains both positive and negative training documents required for the construction of personalized classiﬂers. In this paper, we describe the preliminary version of Categorizor and present its system architecture.
ESTIMATING MULTIVARIATE

The purpose of this study is to examine the forecasting abilities of the same multivariate autoregressive model estimated using two methods. The first method is the "exact method" used by the SCA System from Scientific Computing Associates. The second method is an approximation method as implemented in the MTS system by Automatic Forecasting Systems, Inc. The two methods were used to estimate a five-series multivariate autoregressive model for the Quenouille series on hog numbers, hog prices, corn prices, corn supply, and farm wage rates. The 82 observations were arbitrarily divided into two periods: the first 60 observations were used to estimate the models; then forecasts for one through eight years ahead were calculated for each possible point in the remaining 22 observations. The root mean square error (RMSE) using the SCA-estimated parameters was smaller than the RMSE using the MTS-estimated parameters for 38 of the 40 possible values (five variables by eight forecast horizons) and tied for one point. The average increase in the RMSE when using the MTS parameters was approximately 9 percent. Using the SCA parameters for forecasting provided smaller mean absolute error (MAE) for 35 of the 40 values, with the average increase from using the MTS parameters being approximately 5 . 6 percent. Using the SCA parameters provided smaller mean errors (ME) for 39 of the 40 values, with the average increase from using the MTS parameters being approximately . 023. Thus, the SCA estimation method is shown to provide better forecasts than the MTS method for this one example.
Self-reported physical activity and major adverse events in patients with atrial ﬁbrillation: a report from the EURObservational Research Programme Pilot Survey on Atrial Fibrillation (EORP-AF) General Registry , on behalf of the EORP-AF General Pilot Registry Investigators †

Prevalence of the principal CV risk factors progressively decreased from none to intense physical activity. Lower rates of CV death, all-cause death, and composite outcomes were found in AF patients who reported regular and intense physical activity ( P , 0.0001). Increasing physical activity was inversely associated with CV death/any thromboembolic event (TE)/bleeding in the whole cohort, irrespective of gender, paroxysmal AF, elderly age, or high stroke risk. Any level of physical activity intensity was signiﬁcantly associated with lower risk of CV death/any TE/bleeding at 1-year follow-up. Physical activity was not signiﬁcantly associated with arrhythmia progression. Conclusion Atrial ﬁbrillation patients taking regular exercise were associated with a lower risk of all-cause death, even when we considered various subgroups, including gender, elderly age, symptomatic status, and stroke risk class. Efforts to increase physical activity among AF patients may improve outcomes in these patients.
Numerical Simulation of Cirrus Clouds - Fire Case Study and Sensitivity Analysis

Abstract : The October 28, 1986 FIRE (First ISCCP Regional Experiment) case was simulated using the Regional Atmospheric Modeling System. This three dimensional, mesoscale model was applied in non-hydrostatic and nested-grid mode using explicit, bulk microphysics and radiation. The simulation resulted in very good agreement between observed and model predicted dynamic and cloud fields. We verified cloud height, thickness, areal extent and microphysical composition against GOES satellite imagery, lidar, and aircraft measurements taken during the FIRE Cirrus IFO (Intensive Field Observation). The simulated cirrus lifecycle is examined to determine possible formation, maintenance and dissipation mechanisms. Sensitivity simulations were run to determine long and short wave radiative forcing. Also, a simulation was run with no condensate to examine cloud feedbacks on the environment. Cloud top generation zones, fallstreaks, and layering were simulated. Longwave radiation appeared to be instrumental in developing weak convective activity in the lower layer thereby increasing it's optical depth. Cloud top cooling and cloud base heating affected the flow around the cloud. Secondarily, the effects of three upper boundary conditions on cirrus clouds were studied in a synoptic setting.
Scalable Similarity Self Join in a Metric DHT System (cid:63)

Eﬃcient processing of similarity joins is important for a large class of data analysis and data-mining applications. This primitive ﬁnds all pairs of records within a predeﬁned distance threshold of each other. We present MCAN + , an extension of MCAN (a Content-Addressable Network for metric objects) to support similarity self join queries. The challenge of the proposed approach is to address the problem of the intrinsic quadratic complexity of similarity joins, with the aim of bounding the elaboration time, by involving an increasing number of computational nodes as the dataset size grows. To test the scalability of MCAN + , we used a real-life dataset of color features extracted from one million images of the Flickr photo sharing website.
Institutional Knowledge at Singapore Management University Institutional Knowledge at Singapore Management University

—Coding proﬁciency is essential to software practitioners. Unfortunately, our understanding on coding proﬁciency often translates to vague stereotypes, e.g., “able to write good code”. The lack of speciﬁcity hinders employers from measuring a software engineer’s coding proﬁciency, and software engineers from improving their coding proﬁciency skills. This raises an important question: what skills matter to improve one’s coding proﬁciency. To answer this question, we perform an empirical study by surveying 340 software practitioners from 33 countries across 5 continents. We ﬁrst identify 38 coding proﬁciency skills grouped into nine categories by interviewing 15 developers from three companies. We then ask our survey respondents to rate the level of importance for these skills, and provide rationales of their ratings. Our study highlights a total of 21 important skills that receive an average rating of 4.0 and above (important and very important), along with rationales given by proponents and dissenters. We discuss implications of our ﬁndings to researchers, educators, and practitioners.
Optimizing the Usability of Mobile Job Advertisements: A Multi-Method Approach

— Accessing the Web from mobile devices has become increasingly common even when searching for job information. Nowadays, most job board offerings are mobile-optimized. However, the search results often refer to job advertisements (ads) and external career pages that are not completely optimized for mobile access. For this reason, mobile users may be confronted with inadequate usability or a dissatisfactory user experience. In this context, the purpose of this study is to assess the usability of job ads posted on job portals to identify deficits and best practices. The analysis is based on an exemplary sample of job ads posted on a German job board. As a result, recommendations for a mobile-optimized design of job ads are presented.
hUPF2 Silencing Identiﬁes Physiologic Substrates of Mammalian Nonsense-Mediated mRNA Decay†

Nonsense-mediated mRNA decay (NMD) is a conserved eukaryotic surveillance pathway that selectively degrades aberrant mRNAs with premature termination codons (PTCs). Although a small number of cases exist in mammals, where NMD controls levels of physiologic PTC transcripts, it is still unclear whether the engagement of NMD in posttranscriptional control of gene expression is a more prevalent phenomenon. To identify physiologic NMD substrates and to study how NMD silencing affects the overall dynamics of a cell, we stably down-regulated hUPF2, the h uman homolog of the yeast NMD factor UPF2 , by RNA interference. As expected, hUPF2-silenced HeLa cells were impaired in their ability to recognize ectopically expressed aberrant PTC transcripts. Surprisingly, hUPF2 silencing did not affect cell growth and viability but clearly diminished phosphorylation of hUPF1, suggesting a role of hUPF2 in modulating NMD activity through phosphorylation of hUPF1. Genome-wide DNA microarray expression proﬁling identiﬁed 37 novel up-regulated and 57 down-regulated transcripts in hUPF2-silenced cells. About 60% of the up-regulated mRNAs DSCR1, hUPF1 the hUPF1-
P-splines with an (cid:2) 1 penalty for repeated measures

: P-splines are penalized B-splines, in which ﬁnite order diﬀer- ences in coeﬃcients are typically penalized with an (cid:2) 2 norm. P-splines can be used for semiparametric regression and can include random eﬀects to account for within-subject correlations. In addition to (cid:2) 2 penalties, (cid:2) 1 -type penalties have been used in nonparametric and semiparametric regression to achieve greater ﬂexibility, such as in locally adaptive regression splines, (cid:2) 1 trend ﬁltering, and the fused lasso additive model. However, there has been less focus on using (cid:2) 1 penalties in P-splines, particularly for estimating conditional means. In this paper, we demonstrate the potential beneﬁts of using an (cid:2) 1 penalty in P-splines with an emphasis on ﬁtting non-smooth functions. We propose an estimation procedure using the alternating direction method of multipliers and cross validation, and provide degrees of freedom and approximate conﬁdence bands based on a ridge approximation to the (cid:2) 1 penalized ﬁt. We also demonstrate potential uses through simulations and an application to electrodermal activity data collected as part of a stress study.
Down-regulation of the Sucrose Transporter CsSUT1 Causes Male Sterility by 1 Altering Carbohydrate Supply

29 In plants, male sterility is an important agronomic trait, especially in hybrid crop 30 production. Many factors are known to affect crop male sterility, but it remains 31 unclear whether sucrose transporters (SUTs) participate directly in this process. Here, 32 we identified and functionally characterized the cucumber ( Cucumis sativus ) CsSUT1, 33 a typical plasma membrane-localized energy-dependent high-affinity sucrose-H + 34 symporter. CsSUT1 is expressed in male flowers and encodes a protein that is 35 localized primarily in the tapetum, pollen and companion cells (CCs) of the phloem of 36 sepals, petals, filaments and pedicel. The male flowers of CsSUT1 -RNAi lines 37 exhibited a decrease in sucrose, hexose and starch content, relative to those of the 38 wild type (WT), during the later stages of male flower development, a finding that 39 was highly associated correlated with male sterility. Transcriptomic analysis revealed 40 that numerous genes associated with sugar metabolism, transport and signaling, as 41 well as with auxin signaling, were down-regulated, whereas most MYB transcription 42 factor genes were up-regulated in these CsSUT1 -RNAi lines relative to WT. Our 43 findings demonstrate that male sterility can be induced by RNAi-mediated 44 down-regulation of CsSUT1 expression, through the resultant perturbation in 45 carbohydrate delivery and subsequent alteration in sugar and hormone signaling and up-regulation of specific MYB transcription factors. This knowledge provides a novel 47 approach for bioengineering male sterility in crop plants.
Herbig-Haro outflows associated with high-luminosity young stellar objects-AFGL 2591 and MWC 1080

The discovery of Herbig-Haro (HH) outflows associated with the high-luminosity young stellar objects (YSOs) AFGL 2591 and MWC 1080 is reported. In the case of AFGL 2591, three HH condensations were found approximately in a line through the YSO. The newly-discovered HH objects are associated with the blueshifted lobe of the molecular outflow, and the flow direction is consistent, within the error limits, to that of the molecular outflow
