Accerating Profiling Services by Parallel Database Technology

Full text information retrieval on large document management systems is increasing in popularity, as more users are gaining access to such systems especially by means of WWW interfaces. In addition, more and more systems offer a so-called profiling1 service to keep users informed on newly published documents that match their interests. These growing volumes pose performance requirements that cannot be satisfied by traditional database technology. In this paper we want to report on how parallel database technology can contribute to overcome this problem. Our discussion is exemplified referring to an existing document management system that is currently migrated from a sequential database system to a parallel one. Both the document management system that is used in a number of different real-life applications as well as the parallel database system are developed at our university.2
Multifrequency OFDM SAR in Presence of Deception Jamming

Orthogonal frequency division multiplexing (OFDM) is considered in this paper from the perspective of usage in imaging radar scenarios with deception jamming. OFDM radar signals are inherently multifrequency waveforms, composed of a number of subbands which are orthogonal to each other. While being employed extensively in communications, OFDM has not found comparatively wide use in radar, and, particularly, in synthetic aperture radar (SAR) applications. In this paper, we aim to show the advantages of OFDM-coded radar signals with random subband composition when used in deception jamming scenarios. Two approaches to create a radar signal by the jammer are considered: instantaneous frequency (IF) estimator and digital-RF-memory- (DRFM-) based reproducer. In both cases, the jammer aims to create a copy of a valid target image via resending the radar signal at prescribed time intervals. Jammer signals are derived and used in SAR simulations with three types of signal models: OFDM, linear frequency modulated (LFM), and frequency-hopped (FH). Presented results include simulated peak side lobe (PSL) and peak cross-correlation values for random OFDM signals, as well as simulated SAR imagery with IF and DRFM jammers'-induced false targets.
A case report of de novo missense FOXP1 mutation in a non-Caucasian patient with global developmental delay and severe speech impairment

The FOXP protein family (FOXP1‐4) is a group of transcription factors that play important roles in embryological, immunological, hematological, and speech and language development. Here, we report FOXP1 de novo mutation and severe speech delay in an individual belonging to a non‐Caucasian population.
Simulation evaluation of hybrid SRPT scheduling policies

This paper uses trace-driven simulations to evaluate two novel Web server scheduling policies called K-SRPT and T-SRPT. K-SRPT is a multi-threaded version of SRPT (shortest remaining processing time) that can have up to K jobs in service at a time. T-SRPT is a hybrid policy that dynamically switches from PS (processor sharing) to SRPT when the number of jobs in the system exceeds T, and back to PS when the load diminishes. Slowdown profile plots are used to analyze the performance of these policies relative to PS, SRPT, and FSP (fair sojourn protocol). Simulation results show that these new parameterized policies offer smooth performance tradeoffs between SRPT and PS. Stability issues for T-SRPT are also discussed.
A Trading Rule Test Using Stockholm and U.S. Cross-Listed Securities

This paper examines the relative efficiency of the U.S. and Stockholm Stock Exchanges. Numerous stocks are cross-listed on United States Exchanges and the Stockholm Stock Exchange. We compare the prices of these firms at near-simultaneous trading times. This study is an extension of an earlier work by Jalbert, Moritz and Stewart (2005), who completed an efficiency test on stocks that are cross-listed on the Stockholm and a U.S. stock exchange, finding evidence of an inefficient market. This paper extends this line of work by conducting a trading rule test to provide additional evidence regarding the efficiency of these markets. The results provided here offer additional evidence of efficiency problems between these two markets.
A small cell deployment strategy towards amorphous coverage in the cellular network

Recently, amorphous cells emerge as a promising paradigm in cellular networks to support bursty traffic caused by the user mobility, where dense small cells can cooperate on data delivery to mobile users thus implementing coverage without definite cell shape. In this paper, we propose a novel small cell deployment scheme, aiming at optimizing the network throughput over varying distributions of users' locations. Unlike the traditional research simply assuming one specific distribution of users' locations, our work could deal with the more realistic scenario, where the statistical information of users' locations might change across different time periods. In order to tackle this issue, we formulate the throughput maximization problem over multiple user-location distributions. Then, by applying the simulated annealing algorithm, we develop an iterative location deployment updating algorithm to solve for the efficient deployment as well as cooperation and resource allocation among small cells. Simulation results show that our proposed strategy can effectively improve the system average throughput, cell-edge user throughput, and user fairness as compared to the traditional approach.
Generation of monodisperse particles by using microfluidics: control over size, shape, and composition.

Herein we describe a versatile new strategy for producing monodisperse solid particles with sizes from 20 to 1000 mm. The method involves the formation of monodisperse liquid droplets by using a microfluidic device and shaping the droplets in a microchannel and then solidifying these drops in situ either by polymerizing a liquid monomer or by lowering the temperature of a liquid that sets thermally. This method has the following features: 1) It produces particles with an exceptionally narrow range of sizes. 2) A new level of control over the shapes of the particles is offered. 3) The mechanism for droplet formation allows the use of a wide variety of materials including gels, metals, polymers, and polymers doped with functional additives. 4) The procedure can be scaled up to produce large numbers of particles. A number of methods exist for making inorganic and organic particles with narrow polydispersity. Inorganic colloids are typically prepared by precipitation reactions from organometallic precursors. Polymer colloids with sizes from 20 nm to approximately 1 mm are usually prepared by a variation of emulsion polymerization techniques. Larger beads are accessible through miniemulsion polymerization,
Applying OD to the Public Sector

• D. D. Warrick is an associate professor of management and organizational behavior at the University of Colorado at Colorado Springs where he has shared the Teacher of the Year Award in the College of Business each of the last three years. He is a specialist in management and organization development. Warrick completed his bachelor's and master's degrees at the University of Oklahoma and his doctor's degree at the University of Southern California. Before ;oining the CU faculty, he was a consultant for the Hughes Aircraft Company in Los Angeles where he directed the Middle Management Development Training Program. Warrick and Robert Zawacki are co-editors of a book of readings on organization development to be published by IPMA later this year. One of the most important recent developments in organization development (OD) has been its rapid growth in the public sector. It is now being used in federal, state, and local governments, as well as in educational, religious, health care, social service organizations, and other public agencies. In the military services, the Navy has trained internal change agents to run its own OD workshops,1 the Army has recently launched a comprehensive OD program that will include an OD team at most major bases, and the Air Force teaches OD at the U.S. Air Force Academy and has used external change agents for OD efforts at the academy. The interest in OD that is developing in the public sector is exemplified by the substantial increase in both private and government funds and grants available for OD projects in government agencies, military organizations, and educational institutions.s The rapid growth of OD in the public sector has surfaced some important issues about the applicability of OD to the public sector and the special considerations that must be taken into account in the public sector. In this chapter, the special considerations that occur in each phase of the OD process are discussed, several guidelines for using OD in the public sector are presented, and some conclusions are made about the applicability of OD to the public sector.

Highly Efficient Reproducible Perovskite Solar Cells Prepared by Low-Temperature Processing

In this work, we describe the role of the different layers in perovskite solar cells to achieve reproducible, ~16% efficient perovskite solar cells. We used a planar device architecture with PEDOT:PSS on the bottom, followed by the perovskite layer and an evaporated C60 layer before deposition of the top electrode. No high temperature annealing step is needed, which also allows processing on flexible plastic substrates. Only the optimization of all of these layers leads to highly efficient and reproducible results. In this work, we describe the effects of different processing conditions, especially the influence of the C60 top layer on the device performance.

Efficiency of PreComputed Branches

In this paper we discuss an alternative to the existing branch prediction algorithms, called pre-computed branch prediction. This method does not actually involve prediction, as the branch's outcome is calculated as soon as its last operand is known. We attempted to validate the claim that pre-computed branches give a higher rate of performance than the existing branch prediction methods, by implementing the pre-computed branch algorithm in SimpleScalar. After analyzing our data, we concluded that one does get a higher hit rate and IPC if pre-computed branches are used, which results in increased performance.
Support Vector Machines for Postprocessing of Speech Recognition Hypotheses

In this paper, we introduce an approach to improve the recognition performance of a Hidden Markov Model (HMM) based monophone recognizer using Support Vector Machines (SVMs). We developed and examined a method for re-scoring the HMM recognizer hypotheses by SVMs in a phoneme recognition framework. Compared to a stand-alone HMM system, an improvement of 9.2% was reached on the TIMIT database and 12.8% on the Wallstreet Journal Cambridge database using the hybrid framework.
The Chylomicron: Relationship to Atherosclerosis

The B-containing lipoproteins are the transporters of cholesterol, and the evidence suggests that the apo B48-containing postprandial chylomicron particles and the triglyceride-rich very low density lipoprotein (VLDL) particles play an important part in the development of the plaque both directly and indirectly by their impact on LDL composition. The ratio of dietary to synthesised cholesterol is variable but tightly regulated: hence intervention with diet at best reduces serum cholesterol by <20% andusually <10%. Statins are the mainstay of cholesterol reduction therapy, but they increase cholesterol absorption, an example of the relationship between synthesis and absorption. Inhibition of cholesterol absorption with Ezetimibe, an inhibitor of Niemann Pick C1-like 1 (NPC1-L1), the major regulator of cholesterol absorption, increases cholesterol synthesis and hence the value of adding an inhibitor of cholesterol absorption to an inhibitor of cholesterol synthesis. Apo B48, the structural protein of the chylomicron particle, is synthesised in abundance so that the release of these particles is dependent on the amount of cholesterol and triglyceride available in the intestine. This paper will discuss cholesterol absorption and synthesis, chylomicron formation, and the effect of postprandial lipoproteins on factors involved in atherosclerosis.
Hardware accelerated pattern matching based on Deterministic Finite Automata with perfect hashing

With the increased amount of data transferred by computer networks, the amount of the malicious traffic also increases and therefore it is necessary to protect networks by security systems such as firewalls and Intrusion Detection Systems (IDS) operating at multigigabit speeds. Pattern matching is the time critical operation of current IDS. This paper deals with the analysis of regular expressions used by modern IDS to describe malicious traffic. According to our analysis, more than 64 percent of regular expressions create Deterministic Finite Automaton (DFA) with less than 20 percent of saturation of the transition table which allows efficient implementation of pattern matching into FPGA platform. We propose architecture for fast pattern matching using perfect hashing suitable for implementation into FPGA platform. The memory requirements of presented architecture is closed to the theoretical minimum for sparse transition tables.
Towards Automating the Evaluation of  Holy Quran Recitations: A Pattern Recognition Perspective

The traditional way of learning how to recite Holy Quran is through a method called Talaqqi Musyafahah where students learn face to face from a qualified Quran teacher. As students have limited sessions with Quran teachers, they resort to Computer Aided Learning (CAL) methods to further enhance their quality of recitations. Unfortunately existing applications that aid in CAL don't provide any feedback mechanisms in terms of ratings/scores about the quality of recitations to end users. The benefits of such feedback mechanisms are quite vital to learners of Holy Quran to improve their learning process stage by stage. Till date, the problem of automating evaluation of Holy Quran recitations using computational techniques remains as a open challenge to researchers. In this research we would investigate this potential problem in brief, propose a basic framework based on a pattern recognition perspective to address the problem and report our preliminary results.
Relevance of watermarking in medical imaging

Because of the importance of the security issues in the management of medical information, we suggest the use of watermarking techniques to complete the existing measures for protecting medical images. We discuss the necessary requirements for such a system to be accepted by medical staff and its complementary role with respect with existing security systems. We present different scenarios, one devoted to the authentication and tracing of the images, the second to the integrity control of the patient's record.
Jab1 expression is associated with inverse expression of p27(kip1) and poor prognosis in epithelial ovarian tumors.

PURPOSE Jab1 (Jun activation domain-binding protein 1) has been described as a coactivtor of AP1 transcription factor, and is a subunit of a large protein complex (called the COP9 signalosome). Recent study (K. Tomoda et al., Nature (Lond.), 398: 160-165, 1999) found that Jab1 protein can cause breakdown of p27(kip1) protein in mammalian cells. To investigate whether Jab1 expression is correlated with p27(kip1) protein levels as well as how it might be clinically relevant, we evaluated the expression of Jab1 in a group of epithelial ovarian tumors. EXPERIMENTAL DESIGN Immunohistochemical analysis was performed in 80 cases of ovarian tumors (33 benign ovarian tumors and 47 ovarian carcinomas). Twenty-six of the 80 cases were evaluated by Western blot analysis. RESULTS Jab1 overexpression was detected in 68.1% (32 of 47) of malignant tumors and 33.3% (11 of 33) of benign tumors. The positive ratio of Jab1 was increased from benign to malignant ovarian tumors (P = 0.002). A negative correlation between Jab1 and p27(kip1) expression was found in both benign (P = 0.003) and malignant (P = 0.002) ovarian tumors. No significant correlation was observed between Jab1 overexpression and clinicopathological parameters. Kaplan-Meier survival analysis showed that Jab1 overexpression was significantly associated with poor prognosis of patients (P = 0.049). CONCLUSIONS Jab1 expression is inversely correlated with p27(kip1) expression levels, and Jab1, as a negative regulator of p27(kip1), may be associated with the progression and prognosis of epithelial ovarian tumors.
Functioning and disability in multiple sclerosis from the patient perspective

Multiple sclerosis (MS) has a great impact on functioning and disability. The perspective of those who experience the health problem has to be taken into account to obtain an in-depth understanding of functioning and disability. The objective was to describe the areas of functioning and disability and relevant contextual factors in MS from the patient perspective. A qualitative study using focus group methodology was performed. The sample size was determined by saturation. The focus groups were digitally recorded and transcribed verbatim. The meaning condensation procedure was used for data analysis. Identified concepts were linked to International Classification of Functioning, Disability and Health (ICF) categories according to established linking rules. Six focus groups with a total of 27 participants were performed. In total, 1327 concepts were identified and linked to 106 ICF categories of the ICF components Body Functions, Activities and Participation and Environmental Factors. This qualitative study reports on the impact of MS on functioning and disability from the patient perspective. The participants in this study provided information about all physical aspects and areas of daily life affected by the disease, as well as the environmental factors influencing their lives.
Thememory: Experiencing Thematic Photos in Daily Practice

Thanks to the advanced digital technologies, people can take pictures everyday to record their lives. However, many people almost have no time to browse these tremendous amount of photos and no good way to revisit the treasured photos. Though many methods can display the photos, people still need to allocate a specific timeslot to browse them. To address this problem, a novel design concept, The memory, is developed to utilize users' photos to synthesize program themes, so that the photos will become a part of users' working space and evoke their valuable memories while using their computers. As a user-centric design process, we first recruited 10 professional designers to design program themes according to our described concept, which were further ranked by 31 recruited users. The top ranked templates were implemented according to the extracted design guidelines through the ranked results.
Mapping and Characterization of the Interaction Interface between Two Polypyrimidine-Tract Binding Proteins and a Nova-Type Protein of Solanum tuberosum

Polypyrimidine tract-binding (PTB) proteins are RNA-binding proteins that generally contain four RNA recognition motifs (RRMs). In potato, six cDNAs encoding full-length PTB proteins have been identified. In the present study Nova1-like protein, designated StNova1, was identified as a potential interacting partner of the StPTB proteins via yeast two-hybrid screening. Nova protein is a RNA-binding protein that contains three K-homology (KH) domains. In humans, these proteins are involved in regulation of neuronal RNA metabolism but the role of Nova-like proteins in plants is poorly understood. We have validated this interaction and mapped the protein binding region on StNova1 and StPTB1 and −6 using a novel domain interaction phage display (DIPP) technique. The interaction between the two RNA-binding proteins StPTB1/6 and StNova1 is mediated through linker regions that are distinctly separated from the RRMs. Furthermore, using a random 21-mer phage-peptide library, we have identified a number of peptides with the consensus sequence motif [S/G][V/I][L/V]G that recognize the StPTB proteins. One over-represented peptide that recognizes StPTB6 contains the GVLGPWP sequence that is similar to the GIGGRYP sequence in the glycine-rich linker region between the KH2 and KH3 domains of StNova1. We show, through site-specific mutations, the importance of glycine and proline residues in StNova1-StPTB interactions.
