Synchronous brain activity during cooperative exchange depends on gender of partner: A fNIRS‐based hyperscanning study

Previous studies have shown that brain activity between partners is synchronized during cooperative exchange. Whether this neural synchronization depends on the gender of partner (i.e., opposite or same to the participant) is open to be explored. In current study, we used functional near‐infrared spectroscopy (fNIRS) based hyperscanning to study cooperation in a two‐person game (female–female, female–male, and male–male) while assaying brain‐to‐brain interactions. Cooperation was greater in male–male pairs than in female–female pairs, with intermediate cooperation levels for female–male pairs. More importantly, in dyads with partners with opposite gender (female–male pairs), we found significant task‐related cross‐brain coherence in frontal regions (i.e., frontopolar cortex, orbitofrontal cortex, and left dorsolateral prefrontal cortex) whereas the cooperation in same gender dyads (female–female pairs and male–male pairs) was not associated with such synchronization. Moreover, the changes of such interbrain coherence across task blocks were significantly correlated with change in degree of cooperation only in mixed‐sex dyads. These findings suggested that different neural processes underlie cooperation between mixed‐sex and same‐sex dyadic interactions. Hum Brain Mapp 36:2039–2048, 2015. © 2015 Wiley Periodicals, Inc.
Implementation and Performance Evaluation of RAPID-Cache under Linux

Recent research results [1] using simulation have demonstrated that the RAPID-Cache (Redundant, Asymmetrically Parallel, and Inexpensive Disk Cache) has the potential for significantly improving the performance and reliability of disk I/O systems. To validate whether RAPID-Cache can live up to its promise in a real world environment, we have designed and implemented a RAPID-Cache under Linux operating system as a kernel device driver. As expected, measured performance results are very promising. Numerical results using a popular benchmark program have shown a factor of two to six performance gains in terms of average system throughput. Furthermore, the RAPID-Cache driver is completely transparent to the Linux operating system. It does not require any change to the OS nor the ondisk data layout. As a result, it can be used as an “add-on” to an existing system to obtain immediate performance and reliability improvement.
CELB: Content extraction based on line-block

In this paper, we propose a simple, fast and accurate content extraction method: CELB. Compared with traditional methods, this approach does not parse the DOM trees and uses only information from lines of original HTML documents. We propose a concept called line-block, to extract contents more effectively and a new feature distance-text number (DTN) for distinctions between contents and non-contents. First, we preprocess original HTML documents, and then combine lines into line-blocks. Next, we calculate values of content features for each line-block, and use thresholds to determine whether a lineblock is part of the main content or not. Experiments show satisfied results, especially for the running time.
Measuring the Effectiveness of Retrieval Systems that Create Rankings

The method used to measure the success of a retrieval system is of primary importance. The nature of retrieval engines has been evolving, with very large retrieval engines becoming common, and with the use of ranking becoming widespread. In particular many search engines on the World Wide Web return huge numbers of documents and it is left solely to the user to decide when to stop searching through a list of retrieved items. This paper presents a new measure suitable for testing search algorithms that provide documents in this fashion. The measure is a single figure that is easy to use when comparing different systems.
Filtering of nonlinear systems with sampled noisy data by output injection

This paper concerns with the state estimation problem of nonlinear systems with sampled noisy measurements. The main idea is to exploit a result of the analysis of nonlinear systems, which considers a class of state-space nonlinear models admitting the design of a deterministic observer with linear error dynamics. Such systems are supposed to provide sampled noisy measurements. A consistent filtering technique is then suitably developed, using the same approach of the mentioned classical result.
A Knowledge-Based Software Information System

The difficulty of maintaining very large software systems is becoming more widely acknowledged. One of the primary problems is the need to access information about a complex and evolving system. We are exploring the contribution to be made by applying explicit knowledge representation and reasoning to the management of information about large systems. LaSSIE is a prototype tool (based on the ARGON system) that uses a frame-based description language and classification inferences to facilitate a programmer's discovery of the structure of a complex system. It also supports the retrieval of software for possible re-use in a new development task. Among LaSSIE's features are an integrated natural language front-end (TELI) that allows users to express requests in an informal and compact fashion. Although not without some limitations, LaSSIE represents significant progress over existing software retrieval methods and strictly bottom-up cross-referencing facilities.
Nonparametric on-line background generation for surveillance video

A novel two-stage background generation method is proposed. In the first stage, an intensity-level based statistical approach is employed to identify a variety of background variations. No background training is needed. In the second stage, a background variation based heuristic framework is designed to generate a synchronized background video sequence on-line from the surveillance video. This framework employs both static and dynamic spatial clues in the scene. The quantitative evaluations demonstrate the method can generate more realistic background images than some well-known background modeling techniques.
Integrating tradeoff support in product search tools for e-commerce sites

In a previously reported user study, we found that users were able to perform decision tradeoff tasks more efficiently and commit considerably fewer errors with the example critiquing interface than with the ranked list. We concluded that example-based search tools were likely to be useful particularly for extending the scope of consumer e-commerce to more complex products where decision making is critical. This paper presents results from a follow-up user study quantifying the benefits of tradeoff support. Users were able to refine the quality of their preference structures and improve decision accuracy by up to 57% after performing tradeoff tasks. Tradeoff support also significantly increased users' confidence in their choices. Together, these two studies show that example critiquing enables users to more accurately find what they want and be confident in their choices, while only requiring a level of effort that is comparable to the ranked list interface.
Dielectric Characterization of Poly Ethylene Naphtalene 2,6 Dicarboxylate (PEN) by Thermally Stimulated Currents Technique (TSC)

Abstract The thermally stimulated currents technique has been used to study the relaxations at temperatures between 0° and 160°C in polyethylene naphthalate (PEN). Different material structures were obtained by different treatments. Consequently, for each sample, we have obtained one peak located around 130°C, which is attributed to the dielectric manifestation of the glass transition (α relaxation). The thermal windowing method permitted us to evaluate the activation enthalpy and the relaxation times for each sample. Compensation phenomenon was observed at a temperature Tc, which increases with the crystallinity rate χc. The area under each elementary peak permits calculating the relative dielectric dispersion. The knowledge of this latter and of the relaxation time τ(T) allows 45 to deduce experimentally the real and the imaginary parts of the dielectric permittivity ϵ* for each temperature T and at an equivalent frequency in TSC (f = 10−3 Hz). The imaginary part of ϵ* decreases with χc. The Cole and Cole diagrams were then deduced.
Structure–Function Relationship in Glaucoma Patients With Parafoveal Versus Peripheral Nasal Scotoma

Purpose We evaluated whether the structure–function relationship in glaucoma patients with parafoveal scotoma or peripheral scotoma differs with the use of frequency doubling technology (FDT) or short-wavelength automated perimetry (SWAP) compared to standard automated perimetry (SAP). Methods Glaucoma patients with isolated parafoveal scotoma (PFS) within the central 10° of fixation in 1 hemifield and those with an isolated peripheral nasal step (PNS) within the nasal periphery outside 10° of fixation in one hemifield were studied. Peripapillary retinal nerve fiber layer (RNFL) thickness was measured using spectral-domain optical coherence tomography. The topographic relationships between structure and function were investigated. Results In the PNS group, superotemporal (r2 = 0.300, P = 0.001) and inferotemporal (r2 = 0.302, P = 0.001) RNFL thickness showed significant correlations with the corresponding visual field (VF) sensitivity using linear regression model in SAP. In the PFS group, temporal RNFL thickness was not correlated with nasal mean sensitivity (MS) on SAP (r2 = 0.103, P = 0.065). Using FDT, however, the temporal RNFL thickness was correlated with nasal MS in the PFS group (r2 = 0.277, P = 0.001). Using SWAP, the temporal RNFL thickness was not significantly associated with regional VF sensitivity in the PFS group (r2 = 0.052, P = 0.192). Conclusions In glaucoma with peripheral scotoma, the RNFL thickness was associated significantly with the corresponding VF loss in SAP, FDT, and SWAP. In eyes with PFS, however, the topographic structure–function relationships were not distinct with SAP or SWAP. Frequency doubling technology performed well in terms of structure–function correlation in glaucoma with PFS.
An enhanced multiphase Chan–Vese model for the remote sensing image segmentation

The level set method has been widely used in image segmentation; however, the complexity of the computation has restricted its application field. Also, it is a big challenge to segment remote sensing image mainly because of the complex terrain. In this paper, an enhanced multiphase phase level set method based on the Chan–Vese (C‐V) model is proposed for segmenting remote sensing images. Compared with the C‐V model, two main contributions of the proposed model mainly include the following: First, we introduce a new strategy of initialization in which the contours of the first k biggest connected regions are extracted as the initial curves (k is the number of level set functions); Second, to increase the accuracy, a morphological gradient component is added to the original intensity image. To investigate the effectiveness and efficiency of the proposed model, we have applied it to analyze different kinds of images, including synthetic, real, and remote sensing images. The experimental results have shown that our method is able to achieve better segmentation with less computational consumption compared with the traditional multiphase C‐V model and local and global intensity fitting model.

The ICSI+ multilingual sentence segmentation system

The ICSI+ multilingual sentence segmentation with results for English and Mandarin broadcast news automatic speech recognizer transcriptions represents a joint effort involving ICSI, SRI, and UT Dallas. Our approach is based on using hidden event language models for exploiting lexical information, and maximum entropy and boosting classifiers for exploiting lexical, as well as prosodic, speaker change and syntactic information. We demonstrate that the proposed methodology including pitch- and energyrelated prosodic features performs significantly better than a baseline system that uses words and simple pause features only. Furthermore, the obtained improvements are consistent across both languages, and no language-specific adaptation of the methodology is necessary. The best results were achieved by combining hidden event language models with a boosting-based classifier that to our knowledge has not previously been applied for this task. Index Terms: maximum entropy, boosting, hidden event language models, prosody
A Systems Model of Vesicle Trafficking in Arabidopsis Pollen Tubes[W][OA]

A systems model that describes vesicle trafficking during pollen tube growth in Arabidopsis (Arabidopsis thaliana) was constructed. The model is composed of ordinary differential equations that connect the molecular functions of genes expressed in pollen. The current model requires soluble N-ethylmaleimide-sensitive fusion protein attachment protein receptors (SNAREs) and small GTPases, Arf or Rab, to reasonably predict tube growth as a function of time. Tube growth depends on vesicle trafficking that transports phospholipid and pectin to the tube tip. The vesicle trafficking genes identified by analyzing publicly available transcriptome data comprised 328 genes. Fourteen of them are up-regulated by the gibberellin signaling pathway during pollen development, which includes the SNARE genes SYP124 and SYP125 and the Rab GTPase gene RABA4D. The model results adequately fit the pollen tube growth of both previously reported wild-type and raba4d knockout lines. Furthermore, the difference of pollen tube growth in syp124/syp125 single and double mutations was quantitatively predicted based on the model analysis. In general, a systems model approach to vesicle trafficking arguably demonstrated the importance of the functional connections in pollen tube growth and can help guide future research directions.
Cross Layer Dynamic Resource Management with Guaranteed QoS in MIMO OFDM Systems

In this paper, we have formulated the problem of cross layer throughput-maximized dynamic resource management with guaranteed QoS in MIMO OFDM beamforming systems. In order to reduce of the amount of feedback information and computation complexity, OFDM subcarriers are grouped into subchannels based on the fact that adjacent subcarriers experience the same fading. According to characteristics of various traffics in actual networks, four types of traffics are classified. Different class has different QoS requirements and one connection only belongs to one class. Considering MAC QoS requirements, PHY channel side information (CSI) and connection fairness, the scheduling priority factor (SPF) is defined for each connection. Based on the scheduling priority factor, the suboptimal solutions for the formulated problem are obtained. Packets from different connections are queued at the base station. Scheduling and subchannel allocation are operated at jointly. Then, power allocation and bit loading is made for each packet. The performance of our proposed algorithm is also studied by simulation.
Preschoolers' comprehension of pronouns and reflexives: the impact of the task*

ABSTRACT Pronouns seem to be acquired in an asymmetrical way, where children confuse the meaning of pronouns with reflexives up to the age of six, but not vice versa. Children's production of the same referential expressions is appropriate at the age of four. However, response-based tasks, the usual means to investigate child language comprehension, are very demanding given children's limited cognitive resources. Therefore, they might affect performance. To assess the impact of the task, we investigated learners of Dutch (three- and four-year-olds) using both eye-tracking, a non-demanding on-line method, and a typical response-based task. Eye-tracking results show an emerging ability to correctly comprehend pronouns at the age of four. A response-based task fails to indicate this ability across age groups, replicating results of earlier studies. Additionally, biases seem to influence the outcome of the response-based task. These results add new evidence to the ongoing debate of the asymmetrical acquisition of pronouns and reflexives and suggest that there is less of an asymmetry than previously assumed.
Automated Reverse Engineering Tool

In a package comprising a ceramic member so as to accommodate a semiconductor device, a composite metal body which comprises copper and either one of tungsten and molybdenum is brought into contact with the ceramic member. The composite metal body is provided by impregnating molten copper into a porous block of tungsten or molybdenum and changeable in a thermal expansion coefficient and a thermal conductivity by controlling an amount of copper. The composite metal block may be used as a support for supporting the semiconductor device and/or as a heat sink for dissipating heat radiated from the semiconductor device. Preferably, the composite metal body comprises, by weight, 1-30% of copper and 99-70% of tungsten or molybdenum.
Human Platelet Lysate as a Replacement for Fetal Bovine Serum in Limbal Stem Cell Therapy

ABSTRACT Purpose: To evaluate the use of human platelet lysate (HPL) as an alternative supplement for limbal explant culture.Methods: Culture media were prepared using either 10% pooled HPL (PHPL), single donor HPL, or fetal bovine serum (FBS). Limbal tissues, obtained from the Minnesota Lions Eye Bank, were cultured in each medium on plastic plates or on denuded amniotic membrane (AM). Immunofluorescence staining was performed for ABCG2, tumor protein p63α, and cytokeratin 3 (K3). Quantitative reverse transcriptase polymerase chain reaction (qRT-PCR) was used to evaluate the expression of ABCG2 and p63. Limbal explants grown in each medium were labeled with bromodeoxyuridine (BrdU) to assess the proliferative capacity in each medium. Concentration of growth factors including epidermal growth factor (EGF), vascular endothelial growth factor (VEGF), transforming growth factor-β (TGF-β), and platelet derived growth factor (PDGF) in HPL and PHPL was compared to that in human serum (HS). Results: Immunofluorescence staining on AM showed prominent expression of ABCG2, p63α but sparse expression of K3 in HPL and PHPL supplemented medium. Real time-PCR showed 1.7 fold higher expression of ABCG2 in PHPL supplemented medium (p = 0.03), and similar expression of p63 in HPL and PHPL supplemented medium compared to FBS medium. The proliferation assay showed that LSCs retained their proliferative potential in HPL supplemented medium. Higher concentration of growth factors were found in HPL, compared to HS.Conclusions: Human platelet lysate has higher concentration of grown factors and is effective in maintaining growth and stem cell phenotype of corneal limbal explant cultures.
Genetic Exchange Between Homeologous Sequences in Mammalian Chromosomes Is Averted by Local Homology Requirements for Initiation and Resolution of Recombination

We examined the mechanism by which recombination between imperfectly matched sequences (homeologous recombination) is suppressed in mammalian chromosomes. DNA substrates were constructed, each containing a thymidine kinase (tk) gene disrupted by insertion of an XhoI linker and referred to as a “recipient” gene. Each substrate also contained one of several “donor” tk sequences that could potentially correct the recipient gene via recombination. Each donor sequence either was perfectly homologous to the recipient gene or contained homeologous sequence sharing only 80% identity with the recipient gene. Mouse Ltk− fibroblasts were stably transfected with the various substrates and tk+ segregants produced via intrachromosomal recombination were recovered. We observed exclusion of homeologous sequence from gene conversion tracts when homeologous sequence was positioned adjacent to homologous sequence in the donor but not when homeologous sequence was surrounded by homology in the donor. Our results support a model in which homeologous recombination in mammalian chromosomes is suppressed by a nondestructive dismantling of mismatched heteroduplex DNA (hDNA) intermediates. We suggest that mammalian cells do not dismantle mismatched hDNA by responding to mismatches in hDNA per se but rather rejection of mismatched hDNA appears to be driven by a requirement for localized homology for resolution of recombination.
Ieee Transactions on Software Engineering Static Analysis of Xml Transformations in Java

— XML documents generated dynamically by programs are typically represented as text strings or DOM trees. This is a low-level approach for several reasons: 1) traversing and modifying such structures can be tedious and error prone; 2) although schema languages, e.g. DTD, allow classes of XML documents to be defined, there are generally no automatic mechanisms for statically checking that a program transforms from one class to another as intended. We introduce XACT, a high-level approach for Java using XML templates as a first-class data type with operations for manipulating XML values based on XPath. In addition to an efficient runtime representation, the data type permits static type checking using DTD schemas as types. By specifying schemas for the input and output of a program, our analysis algorithm will statically verify that valid input data is always transformed into valid output data and that the operations are used consistently.
Sequential pattern mining based on a new criteria and attribute constraints

This paper proposes the sequential interestingness as a new evaluation criterion that evaluates a sequential pattern corresponding to the interests of analysts. The sequential pattern is composed of rows of item sets. The criterion satisfies the apriori property. Also, this paper proposes three attribute constraints. These constraints can naturally evaluate relationships of attributes both in an item set and between continuous item sets. In addition, this paper proposes a mining method incorporating the criterion and the constraints. The method can efficiently discover all sequential patterns whose sequential interestingness is larger than or equal to a threshold and that satisfy the constraints. Lastly, this paper verifies the effectiveness of the proposed method by applying the method to medical examination data.
THE CHEMOTACTIC EFFECT OF MIXTURES OF ANTIBODY AND ANTIGEN ON POLYMORPHONUCLEAR LEUCOCYTES

An in vitro technique is described for assessing the chemotactic activity of soluble substances on motile cells. Antibody-antigen mixtures when incubated (37°C) in medium containing fresh (i.e. non-inactivated) normal rabbit serum exert a strong chemotactic effect on rabbit polymorphonuclear leucocytes. Results are described which indicate that, when antibody-antigen complexes are incubated (37°C) in fresh serum, a heat-stable (56°C) substance (or substances) is produced which acts directly as a chemotactic stimulus on the polymorphs. This heat-stable chemotactic substance is not produced when antibody-antigen complexes are incubated in serum which has been heated at 56°C for 30 minutes.
"Outings to your taste": a nutrition program for the elderly.

"Outings to Your Taste" is an innovative program that aims to improve the nutritional status and social network of elderly people who receive home-delivered meals. This article examines participation in one of the program's components, outings to community restaurants. Participation data were collected on-site and information about client characteristics was collected in at-home interview surveys of targeted clients (n = 144). While about half of the clients had tried at least one outing, more than 25% of them participated in at least one third of the outings offered to them. Results indicate that the program attracted a variety of clients in terms of sociodemographic, health, and social isolation characteristics.
