Integrated gene expression analysis of multiple microarray data sets based on a normalization technique and on adaptive connectionist model

Research with microarray gene expression analysis has primarily been on expression profiling based on one set of microarray data. This paper presents a novel approach to integrated analysis and modeling of microarray data from multiple sources. Normalization method is applied to different data sets before they are used together in an adaptive connectionist classification system. The method is demonstrated on a bench-mark case study problem of classifying Diffuse Large B-cell lymphoma (DLBCL) and Follicular lymphoma (FL). For the purpose of comparison, different normalization techniques were applied and connectionist models were created from one or more microarray data sets and then tested on the others. The results show that with the use of proper normalization and modeling techniques, a model based on one set of data can be used to classify microarray data from totally different sources. For the modeling part, evolving connectionist systems (ECOS) are used that allow for new data to be added in an incremental way so that connectionist systems can be built for on-line adaptive learning where new data from various sources can be added into the system.
Are We Missing Post-Thrombotic Syndrome Syndrome? An Orthopaedic Perspective in Lower Limb Arthroplasty

2–5% of patients undergoing hip or knee arthroplasty develop a symptomatic DVT; there is evidence to suggest that without prophylaxis 40–60% of patients have a subclinical DVT. This can be reduced by around half with appropriate thromboprophylaxis; there still remains a significant incidence of subclinical DVT. Therefore, it is important to know, as orthopaedic surgeons, if our patients undergoing large joint arthroplasty are being adversely affected. Post-thrombotic syndrome (PTS) is usually associated with symptomatic DVT, and the purpose of this paper is to address if asymptomatic DVT is also associated with an increased risk of PTS. The majority of evidence gathered does not support a link; therefore, there is no evidence to warrant a change in practice to warn patients of a potential risk or to routinely screen asymptomatic patients.
Utilization of Semantic Annotations in Interactive User Interfaces for Large Documents

With new techniques, such as Microformats or RDFa, for integrating semantics into existing web formats, we expect a strong increase of semantically annotated documents in the web. This paper describes a new approach for utilizing semantic annotations to improve the user interface for large text documents by guiding the user’s attention to semantically annotated text sections using interactive focus+context techniques. We describe an implementation of the concepts in a patent information system.
The Gaussian MIMO Broadcast Channel under Receive Power Protection Constraints

A Gaussian MIMO broadcast channel (GMBC) models the MIMO transmission of Gaussian signals from a transmitter to one or more receivers. Its capacity region and different precoding schemes for it have been well investigated, especially for the case wherein there are only transmit power constraints. In this paper, a special case of GMBC is investigated, wherein receive power constraints are also included. By imposing receive power constraints, the model, called protected GMBC (PGMBC), can be applied to certain scenarios in spatial spectrum sharing, secretive communications, mesh networks and base station cooperation. The sum capacity, capacity region, and application examples for the PGMBC are discussed in this paper. Sub-optimum precoding algorithms are also proposed for the PGMBC, where standard user precoding techniques are performed over a BC with a modified channel, which we refer to as the “protection-implied BC. ” In the protection-implied BC, the receiver protection constraints have been implied in the channel, which means that by satisfying the transmit power constraints on the protection implied channel, receiver protection constraints are guaranteed to be met. Any standard single-user or multi-user MIMO precoding scheme may then be performed on the protection-implied channel. When SINR-matching duality-based precoding is applied on the protection-implied channel, sum-capacity under full protection constraints (zero receive power), and near-sum-capacity under partial protection constraints (limited non-zero receive power) are achieved, and were verified by simulations.
Hardware/Software Partitioning and Static Task Scheduling on Runtime Reconfigurable FPGAs using a SMT Solver

FPGAs are often used together with a CPU as hardware accelerators. A runtime reconfigurable FPGA allows part of the FPGA area to be reconfigured while the remainder continues to operate without interruption, so that hardware tasks can be placed and removed dynamically at runtime. In this paper, we formulate and solve the problem of optimal hardware/software partitioning and static task scheduling for a hybrid FPGA/CPU device, with the optimization objective of minimizing the total schedule length, in the framework of satisfiability modulo theories (SMT) with linear integer arithmetic.
Exploiting user knowledge during retrieval of semantically annotated API operations

Size and complexity of current application programming interfaces (APIs) result in a relatively high amount of effort needed to find operations of desired functionality. With semantic annotation of APIs, the searching process can be automated. This paper identifies and discusses four methods of offering the operation discovery functionality to users. In each method different kind of information is taken as input; each method can be useful for programmers with different background and experience.
The global medial structure of regions in R 3

For compact regionsin R 3 with generic smooth boundary B , we consider geo- metric properties ofwhich lie midway between their topology and geometry and can be summarized by the term "geometric complexity". The "geometric complexity" ofis captured by its Blum medial axis M , which is a Whitney stratified set whose local structure at each point is given by specific standard local types. We classify the geometric complexity by giving a structure theorem for the Blum medial axis M. We do so by first giving an algorithm for decomposing M using the local types into "irreducible components" and then representing each medial component as obtained by attaching surfaces with boundaries to 4-valent graphs. The two stages are described by a two level extended graph structure. The top level describes a simplified form of the attaching of the irreducible medial components to each other, and the second level extended graph structure for each irreducible component specifies how to construct the component. We further use the data associated to the extended graph structures to express topo- logical invariants ofsuch as the homology and fundamental group in terms of the singular invariants of M defined using the local standard types and the extended graph structures. Using the classification, we characterize contractible regions in terms of the extended graph structures and the associated data.
A variable-latency, ultra-low-voltage RISC processor with a new in-situ error detection and correction technique

To overcome significant PVT variation in ultra-low-voltage (ULV) operation, a new in-situ error detection and recovery mechanism is proposed to optimize circuit design for typical-case. The proposed technique detects glitch of a (ctitical-path) circuit output within the setup-time duration of a flip-flop and stalls the clock source, if possible, until the output is stable once an error is detected. Applying the proposed in-situ error detection, a test chip of an ULV 32-bit simple RISC with a 128-point FFT has been implemented with TSMC 40 nm CMOS process. The chip's measurement results confirms the functional correctness of the proposed in-situ error detection mechanism. Comparing that with the simple RISC with conventional worst-case design principle, the proposed variable-latency ULV one reduces approximately 46% energy dissipation. And, with the similar energy consumption, the proposed ULV RISC achieves approximately 1.16 times throughput improvement.
Impact of Configurations of Rapid Intermittent Assimilation of WSR-88D Radar Data for the 8 May 2003 Oklahoma City Tornadic Thunderstorm Case

Abstract Various configurations of the intermittent data assimilation procedure for Level-II Weather Surveillance Radar-1988 Doppler radar data are examined for the analysis and prediction of a tornadic thunderstorm that occurred on 8 May 2003 near Oklahoma City, Oklahoma. Several tornadoes were produced by this thunderstorm, causing extensive damages in the south Oklahoma City area. Within the rapidly cycled assimilation system, the Advanced Regional Prediction System three-dimensional variational data assimilation (ARPS 3DVAR) is employed to analyze conventional and radar radial velocity data, while the ARPS complex cloud analysis procedure is used to analyze cloud and hydrometeor fields and adjust in-cloud temperature and moisture fields based on reflectivity observations and the preliminary analysis of the atmosphere. Forecasts for up to 2.5 h are made from the assimilated initial conditions. Two one-way nested grids at 9- and 3-km grid spacings are employed although the assimilation configuration exp.
A novel dynamic decoupling control algorithm for PMSA by utilizing single neural adaptive controllers

This paper proposes a permanent magnet spherical actuator (PMSA) with three-dimensional magnet array. The application of 3D magnet array improves the output torque significantly. However, as PMSA is a multivariable and nonlinear system, it is very complicate to achieve high accuracy control. Therefore, a novel single neural adaptive control algorithm is proposed in this paper. Compared with the PD and PID control methods, the proposed algorithm is able to realize self-adaptive to the perturbation, which improves the motion stability of PMSA a lot. Euler angles are applied to describe the orientation of rotor. Lagrange equations are utilized to establish the dynamic model of the actuator. As the center of gravity does not coincide with the center of rotor sphere, gravity torque is taken into consideration to enhance the precision of dynamic model. The stability of this algorithm is validated with detailed derivation. Simulation model is formulated in Matlab/Simulink. It proves that the proposed algorithm can make the system track the continuous trajectories in high accuracy.
Fast Correlation Tracking Method based on Circular Projection

An algorithm for a rotation invariant template matching method based on correlation value circular projection target tracking algorithm is proposed in this paper. This algorithm projects the model image as circular and gets the radius and the sum of the same radius pixel value. In order to improve the matching speed and get the illumination invariance, the traditional correlation method is combined with circular projection algorithm. This method computes the correlation value between model image radius pixel sum and the scene image radius pixel sum and gets the maximal that so that it gets the matching result. The experimental results show that this algorithm has good rotate invariance, real-time and high precision property.

Human problem solving: The state of the theory in 1970.

WHEN the magician pulls the rabbit from the hat, the spectator can respond either with mystification or with curiosity. He can enjoy the surprise and the wonder of the unexplained (and perhaps inexplicable), or he can search for an explanation. Suppose curiosity is his main response—that he adopts a scientist's attitude toward the mystery. What questions should a scientific theory of magic answer? First, it should predict the performance of a magician handling specified tasks—producing a rabbit from a hat, say. It should explain how the production takes place, what processes are used, and what mechanisms perform those processes. It should predict the incidental phenomena that accompany the magic—the magician's patter and his pretty assistant—and the relation of these to the mystification process. It should show how changes in the attendant conditions—both changes "inside" the members of the audience and changes in the feat of magic—alter the magician's behavior. It should explain how specific and general magician's skills are learned, and what the magician "has" when he has learned them.
Rho GTPases and Regulation of Cell Migration and Polarization in Human Corneal Epithelial Cells

Purpose Epithelial cell migration is required for regeneration of tissues and can be defective in a number of ocular surface diseases. This study aimed to determine the expression pattern of Rho family small G-proteins in human corneal epithelial cells to test their requirement in directional cell migration. Methods Rho family small G-protein expression was assessed by reverse transcription-polymerase chain reaction. Dominant-inhibitory constructs encoding Rho proteins or Rho protein targeting small interfering RNA were transfected into human corneal epithelial large T antigen cells, and wound closure rate were evaluated by scratch wounding assay, and a complementary non-traumatic cell migration assay. Immunofluorescence staining was performed to study cell polarization and to assess Cdc42 downstream effector. Results Cdc42, Chp, Rac1, RhoA, TC10 and TCL were expressed in human corneal epithelial cells. Among them, Cdc42 and TCL were found to significantly affect cell migration in monolayer scratch assays. These results were confirmed through the use of validated siRNAs directed to Cdc42 and TCL. Scramble siRNA transfected cells had high percentage of polarized cells than Cdc42 or TCL siRNA transfected cells at the wound edge. We showed that the Cdc42-specific effector p21-activated kinase 4 localized predominantly to cell-cell junctions in cell monolayers, but failed to translocate to the leading edge in Cdc42 siRNA transfected cells after monolayer wounding. Conclusion Rho proteins expressed in cultured human corneal epithelial cells, and Cdc42, TCL facilitate two-dimensional cell migration in-vitro. Although silencing of Cdc42 and TCL did not noticeably affect the appearance of cell adhesions at the leading edge, the slower migration of these cells indicates both GTP-binding proteins play important roles in promoting cell movement of human corneal epithelial cells.
Ray shooting in convex polytopes

Let <italic>H</italic> be a set of n halfspaces in <italic>E<supscrpt>d</supscrpt></italic> (where the dimension d ≥ 4 is fixed), and <italic>P</italic>(<italic>H</italic>) the convex polytope defined as their intersection. We show that <italic>P</italic>(<italic>H</italic>) can be preprocessed in time and space <italic>O</italic>(<italic>n</italic><supscrpt>[<italic>d</italic>/2]</supscrpt>/(log <italic>n</italic>)<supscrpt>[<italic>d</italic>/2]-ε</supscrpt>) (for any fixed ε > 0) so that ray shooting queries with rays starting in <italic>P</italic>(<italic>H</italic>) can be answered in time <italic>O</italic>(log <italic>n</italic>). This improves previous bounds by obtaining optimal query time and by improving the product <italic>Q</italic>(<italic>n</italic>)<italic>S</italic>(<italic>n</italic>)<supscrpt>1/[<italic>d</italic>/2]</supscrpt> (<italic>Q</italic>(<italic>n</italic>) and <italic>S</italic>(<italic>n</italic>) denoting query time and storage of a data structure for this problem) to <italic>O</italic>(<italic>n</italic>(log <italic>n</italic>)<supscrpt>ε</supscrpt>) for an arbitrarily small ε > 0. By a well known lifting transformation, the results imply the same bounds for nearest (or furthest) neighbor queries in space of one dimension lower, which is an improvement in itself. We furthermore show that a structure for the ray shooting problem can be dynamically maintained under a sequence of random insertions, using the history of the maintenance process for the polytope as a point location data structure. The expected update time is <italic>O</italic>(<italic>m</italic><supscrpt>[<italic>d</italic>/2]-1</supscrpt>(log <italic>m</italic>)<supscrpt><italic>O</italic>(1)</supscrpt>), the query time for ray shooting queries is <italic>O</italic>(log<supscrpt>2</supscrpt> <italic>m</italic>) with high probability, where <italic>m</italic> is the current number of points.
Evidence on the importance of cognitive ability tests for NFL quarterbacks: what are the relationships among Wonderlic scores, draft positions and NFL performance outcomes?

ABSTRACT Employing data on National Football League (NFL) quarterbacks drafted between 2002 and 2012, the authors consider whether factors correlated with a quarterback being more productive in the NFL are the same factors that correlate with an improved draft position. In particular, the authors consider the relevance of scores on the Wonderlic test. Contrary to all prior literature on the subject, the authors find that performance on the Wonderlic test is positively correlated with NFL performance. However, the authors find no clear evidence that Wonderlic scores are correlated with draft position. Beyond this primary finding, the authors reveal many other interesting results that should help researchers better understand a quarterback’s progression from college to the NFL.

Physical Interpretation and Implications of Similarity Transformations in Coupled Resonator Filter Design

This paper discusses the physical interpretation and implications of similarity transformations for applications in coupled resonator filter design. It is shown that certain similarity transformations contain important ldquoglobalrdquo information that can be used to get insight into the workings of microwave bandpass filters. Instead of focusing on the effect a similarity transformation has on the original coupling matrix, the change of basis that the similarity transformation represents is considered the main operation. For a filter of order N that is designed as a set of N coupled resonators, it is shown that the transversal matrix is equivalent to using the global eigenmodes of the entire structure as a basis. The transversal matrix emerges as a universal and natural representation of coupled resonator bandpass filters of arbitrary orders, responses, and topologies. It can be used as an equivalent circuit in the optimization and diagnosis of bandpass coupled resonator filters. The results of this study have far reaching implications not only for the theory and design of microwave filters, but other circuits as well.

This paper presents an efficient testing technique that combines Branch Search with Korel's chaining approach. Proposed technique automatically generates test data in order to obtain complete branch coverage in software testing.
The Impact of the Anti-Predatory Lending Laws on Mortgage Volume

In this paper, I test the hypothesis that anti-predatory lending laws inhibited the volume of mortgage lending during the housing-bubble period. I use cross-state variation in the strictness of these laws and their application only to mortgage refinancing as opposed to home purchases to develop a difference-in-difference estimate of the impact of these laws on mortgage volume. Consistent with my hypothesis, I find that states with stricter laws had lower mortgage refinancing volume but exhibited no difference in home purchase mortgage volume. I also test whether by restricting mortgage refinancing, these laws impacted household expenditures and find that the laws reduced household expenditures. ∗I thank my advisor, Harrison Hong, for invaluable advice and support. I am also grateful to seminar participants at Princeton University for helpful comments. All errors are my own. †Address: The Bendheim Center for Finance, 26 Prospect Ave, Princeton University, Princeton, NJ 08540-5296. Email: hyunchoi@princeton.edu
China's Business Cycles: The International Dimension

This paper investigates the causes of China’s output and trade balance fluctuations in the period of 1985–2000, with special attention to the role of the real exchange rate. The effects of four types of shock – the foreign supply shock, the domestic supply shock, the relative demand shock and the nominal shock – are examined, employing a near -VAR that embodies the long-run properties of a ‘dependent economy’ model. Two findings emerge as important: First, domestic shocks are the main source of output fluctuations, indicating a lack of synchronization between China’s business cycles and those of its trading partners. Second, the trade balance is little affected by nominal shocks. Doubt is thus cast on the claim that monetary measures would suffice to redress China’s trade ‘imbalance’.
