Spatial and temporal communication theory using adaptive antenna array

An adaptive antenna array or a smart antenna is named a software antenna because it can form a desired antenna pattern and adaptively control it if an appropriate set of antenna weights is provided and updated in software. It can be a typical tool for realizing a software radio. An adaptive antenna array can be considered an adaptive filter in the space and time domains for radio communications, so communication theory can be generalized from a conventional time domain into both space and time domains. This article introduces a spatial and temporal communication theory based on an adaptive antenna array, such as spatial and temporal channel modeling, equalization, optimum detection for single-user and multi-user CDMA, precoding in a transmitter, and joint optimization of both transmitter and receiver. Such spatial and temporal processing promises significant improvement of performance against multipath fading in mobile radio communications.
Coordinative Structure of Manipulative Hand-Movements Facilitates Their Recognition

Manipulative hand movements involve coordinated movements of the fingers to manipulate an object within the hand, and are classified as either simultaneous or sequential. Simultaneous hand movements are characterized by single coordinated patterns of digit movements, while sequential hand movements involve sequences of such patterns. Here, we investigate the extent of the coordination among 15 hand-joints during simultaneous hand movements, and demonstrate that it leads to a concise representation that facilitates movement recognition. Principal component analysis (PCA), performed in the 15-dimensional (15-D) joint-space, indicates that the first principal-component captures more than 98% of the variability in individual hand movements. Consequently, the first principal direction provides a 15-D feature-vector that describes the underlying-coordination and can be used for automatic recognition. We evaluated this recognition strategy on a set of nine simultaneous hand-movements using a database of six users, each performing six sessions. A dedicated classifier for each user resulted in recognition rates of 97.0plusmn4. 7% during testing, while a single generic classifier achieved 95.2plusmn2. 5% recognition rates. We conclude that the suggested feature-vector captures the invariant structure of simultaneous hand-movements, facilitates their recognition, and may provide insight into motor planning
Orchestration of Arrowhead services using IEC 61499: Distributed automation case study

This paper presents a novel approach to automation of flexible manufacturing systems with mechatronic intelligence and distributed control. The mechatronic intelligence layer is implemented using a combination of wireless sensor/actuator networks with service-oriented architecture, where services are located at the device level, as well as in local and global Clouds following the Arrowhead framework.
The Transposition Frequency of Tag1 Elements Is Increased in Transgenic Arabidopsis Lines

Tag1 was identified as a highly active endogenous transposable element in transgenic Arabidopsis thaliana Landsberg erecta plants carrying the maize transposable element Activator (Ac). Here, we describe experiments designed to determine the basis for the high activity of Tag1. The frequency of transposition of Tag1 elements was compared in lines containing or lacking Ac transposase to assess the effect of Ac transposase on Tag1 activity. Three populations of nontransgenic plants, including nontransformed regenerants, were also analyzed. The high level of activity of Tag1 did not correlate with the presence or absence of Ac transposase but was significantly higher in transgenic lines. This result was maintained through at least six generations after transformation. These data suggest that Tag1 transposition is stimulated by processes that occur during the Agrobacterium transformation and that thereafter remain active. Two Tag1 elements are tightly linked in the Landsberg erecta genome and map to the lower arm of chromosome 1. Tag1 elements were found in only a few A. thaliana ecotypes but were present in four other Arabidopsis species.
Wireless Insufflation of the Gastrointestinal Tract

Despite clear patient experience advantages, low specificity rates have thus far prevented swallowable capsule endoscopes from replacing traditional endoscopy for diagnosis of colon disease. One explanation for this is that capsule endoscopes lack the ability to provide insufflation, which traditional endoscopes use to distend the intestine for a clear view of the internal wall. To provide a means of insufflation from a wireless capsule platform, in this paper we use biocompatible effervescent chemical reactions to convert liquids and powders carried onboard a capsule into gas. We experimentally evaluate the quantity of gas needed to enhance capsule visualization and locomotion, and determine how much gas can be generated from a given volume of reactants. These experiments motivate the design of a wireless insufflation capsule, which is evaluated in ex vivo experiments. These experiments illustrate the feasibility of enhancing visualization and locomotion of endoscopic capsules through wireless insufflation.
SEMEX: Toward On-the-fly Personal Information Integration

A camping assembly the parts of which are rapidly connectible and disconnectible for particular use in automobile vans is secured to a van deck via a set of laterally related longitudinals supported on edge by transverse connecting members over which lie a set of panels capable of constituting sleeping accomodation when the occupants lie transverse to the van axis, or seating with provision for a table, by lifting two adjacent pairs of hingedly connected panels such that the center pair assumes the sub-vertical thus providing two opposite seat-backs while the outer pair function as seats, all extending transversely over the van axis, with space for a table between two panels when one is slid into said seat position, storage accommodation existing between said longitudinals and connecting members.
USHEF and USAAR-USHEF participation in the WMT15 QE shared task

We present the results of the USHEF and USAAR-USHEF submissions for the WMT15 shared task on document-level quality estimation. The USHEF submissions explored several document and discourse-aware features. The USAARUSHEF submissions used an exhaustive search approach to select the best features from the official baseline. Results show slight improvements over the baseline with the use of discourse features. More interestingly, we found that a model of comparable performance can be built with only three features selected by the exhaustive search procedure.
Data Security in Occupational Health

Occupational health nurses are increasingly using computer systems in the delivery of efficient, high-quality occupational health services. However, potential breaches in data security are posing more risks to these data systems. The purpose of this article is to address concerns related to data security in occupational health nursing. Occupational health nurses must protect the personal health information of employees by proactively developing methods to ensure data security.
Another proof of undecidability for the correspondence decision problem - Had I been Emil Post

In 1946 Emil Leon Post (Bulletin of Amer. Math. Soc. 52 (1946), 264 - 268) defined a famous correspondence decision problem which is nowadays called the Post Correspondence Problem, and he proved that the problem is undecidable. In this article we follow the steps of Post, and give another, simpler and more straightforward proof of the undecidability of the problem using the same source of reduction as Post original did, namely, the Post Normal Systems.
Video summarization using genetic algorithm and information theory

Video processing techniques based on pattern recognition methods and machine vision is one of the interesting research fields which attract many researchers. In this paper, we proposed a novel method for video summarization using genetic algorithm based on information theory. Our method relies on the mutual information for video summarization. The information theory measure provides us with better results because it extracts the inter-frame information. We present that it is a suitable factor for summarizing video, which maintains its integrity.
A coronal wave and an asymmetric eruptive filament in SUMER, CDS, EIT, and TRACE co-observations

The objectives of the present study is to provide a better physical understanding of the complex inter-relation and evolution of several solar coronal features comprising a double-peak flare, a coronal dimming caused by a CME, a CME-driven compression, and a fast-mode wave. For the first time, the evolution of an asymmetric eruptive filament is analysed in simultaneous SUMER spectroscopic and TRACE and EIT imaging data. We use imaging observations from EIT and TRACE in the 195A channel and spectroscopic observations from the CDS in a rastering and SUMER in a sit-and-stare observing mode. The SUMER spectra cover spectral lines with formation temperatures from logT(K) ~ 4.0 to 6.1. Although the event was already analysed in two previous studies, our analysis brings a wealth of new information on the dynamics and physical properties of the observed phenomena. We found that the dynamic event is related to a complex flare with two distinct impulsive peaks, one according to the GOES classification as C1.1 and the second - C1.9. The first energy release triggers a fast-mode wave and a CME with a clear CME driven compression ahead of it. This activity is related to, or possibly caused, by an asymmetric filament eruption. The filament is observed to rise with its leading edge moving at a speed of ~300 km/s detected both in the SUMER and CDS data. The rest of the filament body moves at only ~150 km/s while untwisting. No signature is found of the fast-mode wave in the SUMER data, suggesting that the plasma disturbed by the wave had temperatures above 600 000 K. The erupting filament material is found to emit only in spectral lines at transition region temperatures. Earlier identification of a coronal response detected in the Mg X 609.79 A line is found to be caused by a blend from the O IV 609.83 A line.
UK Appraisal of Clinical and Cost-Effectiveness of Cochlear Implantation by the National Institute for Health and Clinical Excellence

NICE (National Institute for Health and Clinical Excellence) is an independent organization responsible for national guidance on promoting good health and preventing and treating ill health. As part of the process to evaluate cochlear implants (CI) in children and adults with severe to profound sensorineural hearing loss, NICE commissioned PenTAG (Peninsula Technology Assessment Group, Institute for Health Services Research, Peninsula Medical School, Universities of Exeter and Plymouth, UK) to complete a clinical and cost-effectiveness assessment. This was to be addressed by answering the questions:
Tight embedding of subspaces of "L"p in "l n,p" for even "p"

Using a recent result of Batson, Spielman and Srivastava, We ob- tain a tight estimate on the dimension ofn, p an even integer, needed to almost isometrically contain all k-dimensional subspaces of Lp. In a recent paper (BSS) Batson, Spielman and Srivastava introduced a new method for sparsification of graphs which already proved to have functional analytical applications. Here we bring one more such application. Improving over a result of (BLM) (or see (JS) for a survey on this and related results), we show that for even p and for k of order n 2/p any k dimensional subspace of Lp nicely embeds inton . This removes a log factor from the previously known estimate. The result in Theorem 2 is actually sharper than stated here and gives the best possible result in several respects, in particular in the dependence of k on n. The theorem of (BSS) we shall use is not specifically stated in (BSS), but is stated as Theorem 1.6 in Srivastava's thesis (Sr): Theorem 1 (BSS) Suppose 0 < " < 1 and A = P m=1 viv T are given, with vi column vectors in R k . Then there are nonnegative weights fsig m=1 , at most dk=" 2 e of which are nonzero, such that, putting ˜ A = P m=1 siviv T ,
Everyone's Invited: A New Paradigm for Evaluation on Non-Transferable Datasets

Social media data mining and analytics has stimulated a wide array of computational research. Traditionally, individual researchers are responsible for acquiring and managing their own datasets. However, the temporal nature of social data, the challenges involved in correctly preparing a dataset, the sheer scale of many datasets, and the proprietary nature of many data sources can make extending and comparing computational methods difficult and often impossible. In light of this, because replicability is a fundamental pillar of the scientific process and because method comparison is essential to characterizing computational advancements, we require an alternative to the traditional model of researcher-owned datasets. In this paper we propose FREESR, a framework that gives researchers the ability to develop and test method performance without requiring direct access to “shared” datasets. As a case study and first community resource, we have implemented the FREESR paradigm around the task of Tweet geolocation. The implementation showcases the clear suitability of this framework for the social media research context. Beyond the implementation, we see the FREESR paradigm as being an important step towards making study reproducibility and method comparison more principled and ubiquitous in the social media research community.
Web testware evolution

Web applications evolve at a very fast rate, to accommodate new functionalities, presentation styles and interaction modes. The test artefacts developed during web testing must be evolved accordingly. Among the other causes, one critical reason why test cases need maintenance during web evolution is that the locators used to uniquely identify the page elements under test may fail or may behave incorrectly. The robustness of web page locators used in test cases is thus critical to reduce the test maintenance effort. We present an algorithm that generates robust web page locators for the elements under test and we describe the design of an empirical study that we plan to execute to validate such robust locators.
Dependency Relationship Based Decision Combination in Multiple Classifier Systems

Although many decision combination methods have been proposed, most of them did not focus on dependency relationship among classifiers ID combining multiple decisions That makes classification performance of combining multiple decisions be degraded and biased, in case of adding highly dependent inferior classifiers. To overcome such weaknesses and obtain robust classification performance, the present study used dependency relationship for better combining multiple decisions In order to identify dependency relationship by observing outputs of multiple classifiers, two methods are used on the basis of first-order dependency relationship One is to use the concept of mutual information, and the other one is to use the concept of statistically measured association The first-order dependencies identified are used to combine multiple decisions, using Bayesian formalism A number of multiple classifier systems are applied to totally uncontrained on-line handwritten numerals and the English alphabet recognition. The experimental results show that the classification performance of a multiple classifier system is superior to that of individual classifiers. Also, they show that considering the dependency relationship outperforms others in accuracy, when the highly dependent inferior classifiers are added.
View planning for automated three-dimensional object reconstruction and inspection

Laser scanning range sensors are widely used for high-precision, high-density three-dimensional (3D) reconstruction and inspection of the surface of physical objects. The process typically involves planning a set of views, physically altering the relative object-sensor pose, taking scans, registering the acquired geometric data in a common coordinate frame of reference, and finally integrating range images into a nonredundant model. Efficiencies could be achieved by automating or semiautomating this process. While challenges remain, there are adequate solutions to semiautomate the scan-register-integrate tasks. On the other hand, view planning remains an open problem---that is, the task of finding a suitably small set of sensor poses and configurations for specified reconstruction or inspection goals. This paper surveys and compares view planning techniques for automated 3D object reconstruction and inspection by means of active, triangulation-based range sensors.
Effect of Heat Treatment on Pore Architecture and Associated Property Changes in Plasma Sprayed TBCs

Plasma sprayed Thermal Barrier Coatings (TBCs) exhibit many interlamellar pores, voids and microcracks. These microstructural features are primarily responsible for the low global stiffnesses and the low thermal conductivities commonly exhibited by such coatings. The pore architecture thus has an important influence on such thermophysical properties. In the present work, the effect of heat treatment (at temperatures up to 1400°C, for times of up to 10 hours) on the pore architecture in detached YSZ top coats has been characterised by Mercury Intrusion Porosimetry (MIP) and gas-sorption techniques. While the overall porosity level remained relatively unaffected (at around 10-12%) after the heat treatments concerned, there were substantial changes in the pore size distribution and the (inter-connected) specific surface area. Fine pores (<~50 nm) rapidly disappeared, while the specific surface area dropped dramatically, particularly at high treatment temperatures (~1400°C). These changes are thought to be associated with intra-splat microcrack healing, improved inter-splat bonding and increased contact area, leading to disappearance of much of the fine porosity. These microstructural changes are reflected in sharply increased stiffness and thermal conductivity. Measured thermal conductivity data are compared with predictions from a recently-developed analytical model, using the deduced inter-splat contact area results as input parameters. Good agreement is obtained, suggesting that the model captures the main geometrical effects and the pore size distribution measurements reflect the most significant microstructural changes.

Ultrastructural and biochemical analysis of the stress granule in chicken embryo fibroblasts

The ultrastructure and biochemical composition of cytoplasmic particles that form in chicken embryo fibroblasts during stress have been analyzed. We showed previously that these particles contained the small stress protein, sp 24, and antibodies specific to sp 24 were used here to identify the stress granule. In thin sections, the stress granule was a densely staining, membraneless, cytoplasmic body and appeared as a highly condensed area of cytoplasm in freeze-fracture preparations. Hypotonic swelling of cells before freeze-fracture analysis revealed a basketlike structure composed of interconnecting protein cables. No other proteins could be cross-linked to sp 24 when stress granules were treated with dithiobis-(succinimidyl propionate). High resolution autoradiographic analysis with [3H]uridine failed to identify any associated RNA synthesized in the period immediately before the stress. Thus the stress granule appears to be composed predominantly of sp 24 aggregates. Sp 24 could be purified to homogeneity from the stress granule by solubilization in 8 M urea and anion exchange chromatography.
Investigating the Origins of Toxic Response in TiO2 Nanoparticle-Treated Cells

Titanium dioxide nanoparticles (TiO2 NPs) are widely used in sunscreens, cosmetics and body implants, and this raises toxicity concerns. Although a large number of reports claim that they are safe to use, others claim that they induce reactive oxygen species formation and can be carcinogenic. In this study, the origins of toxic response to TiO2 NPs were investigated by using Surface-enhanced Raman spectroscopy (SERS) which provides multidimensional information on the cellular dynamics at single cell level without any requirement for cell fixation. Three cell lines of vein (HUVEC), lung carcinoma (A549) and skin (L929) origin were tested for their toxic response upon exposure to 20, 40, 80 and 160 µg/mL anatase-TiO2 NPs for 24 h. It was demonstrated that the level of toxic response is both cell line and dose-dependent. L929 fibroblasts were the most resistant cell line to oxidative stress whereas in HUVEC and A549, cell lines collagen and lipid deformation were observed, respectively.
A novel role for lbx1 in Xenopus hypaxial myogenesis

We have examined lbx1 expression in early X. laevis tadpoles. In contrast to amniotes, lbx1 is expressed in all of the myoblasts that contribute to the body wall musculature, as well as in a group of cells that migrate into the head. Despite this different expression, the function of lbx1 appears to be conserved. Morpholino (MO) knockdown of lbx1 causes a specific reduction of body wall muscles and hypoglossal muscles originating from the somites. Although myoblast migratory defects are observed in antisense MO injected tadpoles targeting lbx1, this results at least in part from a lack of myoblast proliferation in the hypaxial muscle domain. Conversely, overexpression of lbx1 mRNA results in enlarged somites, an increase in cell proliferation, but a lack of differentiated muscle. The control of cell proliferation is linked to a strong downregulation of myoD expression in gain-of-function experiments. Co-injection of myoD mRNA with lbx1 mRNA eliminates the overproliferation phenotype observed when lbx1 is injected alone. The results indicate that a primary function of lbx1 in hypaxial muscle development is to repress myoD, allowing myoblasts to proliferate before the eventual onset of terminal differentiation.
Successful outcome of intra-arterial tissue plasminogen activator treatment for patient with acute middle cerebral artery occlusion beyond the 6-hour time window : case series report of 3 middle-aged and aged patients

Local intra-arterial recombinant tissue plasminogen activator (IA rt-PA) is an effective treatment for acute middle cerebral artery (MCA) occlusion with a time window of 6 hr. However, the outcomes of IA rt-PA treatment beyond the 6-hour time window are largely unknown. Here we reported three successful cases of intra-arterial thrombolysis by using small dose of rt-PA in patients with acute MCA occlusion over the 6-hour time window. Three patients had sudden onset of symptoms. Emergency angiography showed the complete occlusion of M1 segment of the MCA in the three cases. Neurological examination showed severe neurological dysfunction at admission (National Institutes of Health Stroke Scale [NIHSS] graded as 12, 11 and 13, respectively). After local thrombolysis treatment with rt-PA (total dose of 6 mg, 10 mg and 6 mg, respectively), the occluded MCA gradually recanalized. Postoperative CT showed no hemorrhagic transformation in Case 1 and Case 2, and asymptomatic intracranial hemorrhage in Case 3. All three patients had a good recovery with slight paresis and mild aphasia after 2 weeks (NIHSS graded as 0, 1, and 1, respectively). The mRS of the three patients was 0 at day 90. Our reported suggested that low dose of rt-PA arterial thrombolysis may be a feasible treatment option for acute MCA occlusion in middleaged and aged patients, even beyond the 6-hour window.
