Perspectives of Use of Diagnostic Mirrors with Transparent Protection Layer in Burning Plasma Experiments

We evaluate using of metal mirrors over‐coated with transparent protection layer for the in‐vessel diagnostic systems in reactor‐grade fusion devices. Ideally, these should satisfy the contradictory demands of high reflectivity and small rate degradation when being bombarded by CX atoms. The serious threat to the performance of diagnostic mirrors is surface contamination with carbon‐based material eroded from carbon tiles. Via coupling the protective layer to a bulk mirror we can mitigate the deposit infiuence on the reflectance spectra. The regards are given to survivability in plasma environment of protected coated metallic mirrors.
Gold Nanocages: A Novel Class of Multifunctional Nanomaterials for Theranostic Applications

Gold nanocages represent a novel class of nanostructures, well‐suited for biomedical applications. They can be readily prepared via the galvanic replacement reaction between silver nanocubes and chloroauric acid. Their optical resonance peaks can be easily and precisely tuned to the near‐infrared region from 650–900 nm, the transparent window for blood and soft tissue. Furthermore, their surface can be conveniently conjugated with various ligands for targeting cancer. In this feature article, we highlight recent advances in the large‐scale synthesis of gold nanocages and their applications in cancer diagnosis and treatment. Specifically, we have scaled up the production of gold nanocages for in vivo studies and evaluated their tumor targeting capabilities. We have also demonstrated their use as contrast agents for photoacoustic tumor imaging and the mapping of sentinel lymph node, as photothermal transducers for cancer treatment, and as smart carriers for controlled release with a near‐infrared laser.
Impacts of land use on nutrient distribution and vegetation composition of freshwater wetlands in northern Belize

The coastal plain of northern Belize consists of relatively undisturbed freshwater marshes that are strongly phosphorus-limited and characterized by monodominant stands or mixtures of emergent macrophytes. In order to assess the impact of agricultural activities on the nutrient dynamics and plant species composition in adjacent wetlands, we sampled along transects in 40 marshes—20 located downslope from agricultural fields and 20 bordered by scrub or broadleaf forest. Soil, water, and plant tissue samples were collected for nutrient analyses, and plant species composition was recorded at points along transects during both the wet and dry seasons. Marshes downslope from agricultural activity had significantly greater percent cover of Typha domigensis, a competitive dominant in the system (20% vs. 6%) and significantly more soil phosphorus (128–144 μg*cm−3) than marshes bordered by forest (70–98 μg*cm−3). Plant tissue P content was positively correlated with soil P content but not with soil N for Typha (r=0.55) and Eleocharis spp. (r=0.72). Canonical Correspondence Analysis (CCA) identified soil P as the variable most strongly affecting Typha abundance. Abundance of species common to unimpacted marshes (Eleocharis spp., Cladium jamaicense) was negatively correlated with soil P. Further intensification of agriculture in this region may result in expansion of T. domingensis, as has occurred in the Florida Everglades.
FEM Stress Analysis and the Sealing Performance Prediction of Pipe Flange Connections under External Bending Moments and Internal Pressure

The contact gasket stress distribution and the hub stress of pipe flange connection under external bending moment and internal pressure are analyzed using three dimensional elasto-plastic FEM. The effect of external bending moment on the sealing performance is evaluated and the amount of the leakage is predicted using the contact gasket stress distribution. From the obtained FE analyses, it is found that a large decrease in the contact gasket stress at the tension side occurs and a small increase at the compression side occurs. The difference in the change in the contact gasket stress occurs due to the non-linear hysteresis characteristics of stress-contract curve of the gasket (spiral wound gasket) used in the study. The FE analyses also suggest that the loading order, that is, the following two cases are analyzed, 1) an internal pressure is applied at first and then the external bending moment is applied to the connection, 2) the external bending moment is applied to the connection and then the internal pressure is applied, also affects the sealing performance due to the non-linear contract characteristic of the gasket. The sealing performance when the external bending moment is applied prior to the internal pressure is degraded more than that when the internal pressure is applied prior to the external bending moment. The leakage tests using helium (He) gas and the measurement of the hub stress were carried out, and then the amount of the leakage was measured. The amount of leakage from the connection is predicted using the contact gasket stress distribution obtained from FE analyses and the results are in a fairly good agreement with the measured results. It is found that the effect of the external bending moment is substantial on the sealing performance of the connections. Also, the calculated hub stresses are fairly consistent with the measured results.

This paper present an approach of Domain Analysis to developing Radio Frequency Indentification Systems in Supply Chain Management.
Semi-Blind Channel Estimation Using the EM Algorithm in Iterative MIMO APP Detectors

We consider channel estimation in multiple-input multiple-output (MIMO) systems using iterative detection at the receiver. Space-time bit-interleaved coded modulation (BICM) and soft-input soft-output maximum a posteriori (MAP) symbol detection and decoding are considered. Channel coefficients are updated at each iteration of the detector using a semi-blind estimation approach based on the expectation maximization (EM) algorithm. We first show that a "classical" and non-optimized EM implementation, as already proposed in some previous works, gives a biased estimate of the channel coefficients. We then try to optimize the EM implementation and propose a modification to it that provides an unbiased channel estimate and leads to a better convergence of the iterative detector. We show that considerable improvement in the receiver performance can be obtained by using our proposed modified unbiased (MU) EM algorithm, especially for large number of transmit antennas and short training sequences. We also show that when MIMO signal detection is strongly asymmetric in the sense of too few receive antennas, the EM-based channel estimation may be of little interest. Moreover, we consider a simple semi-blind estimation scheme, based on hard decisions on reliable decoded data bits, and compare its performance with the EM based estimation methods
Strategic Entrepreneurial Orientation and Small Business Growth

This chapter aims to define a coherent theoretical framework enabling a broader understanding of the strategic entrepreneurial orientation (SEO) and to evaluate their effects on small firm growth. A sample made up of 211 small Portuguese firms from various different sectors of activity was surveyed by questionnaire. The results demonstrate how the life-cycle of companies, their resources, capacities, motivations and surrounding environment all influence the SEO of small companies. The empirical evidence shows how SEO, and across four specific dimensions – proactiveness, innovativeness, risk taking and competitive aggressiveness, clearly impacts on the growth of these small firms. The study contributes both theoretically (through advancing knowledge on the field of strategic factors for small business growth) and practically (when designing support policies strategically orientated towards small firms).
Processing of the Data Obtained with the Advanced Doppler Velocymeter

We present data obtained after a 2 years period of monitoring the wave’s parameters in an off-shore location. We have used the location of a working petroleum platform situated at: N44031’, E29034’ at 50 km from land and 80 km NE from Constanta Harbor, in the Romanian Black Sea waters. We describe monitoring systems used.and their solution. The Advanced Doppler Velocymeter (ADV) for parameters of marine waves is based on Doppler effect and it is composed of a transmitter at a frequency of 10 MHz and of 3 receivers which are equidistant from 1200. Data storage on the HDD PC, with the possibility of take-over and normal review (ASCII file). We can get the values of the speed and current division marine tide amplitude and direction of the wave at each measurement, the number of measurements, date, hour, minute and second of measurement, as well as other parameters, both as numeric values and a graph having abscissa registration number. This monitoring, which comprises the period of one year including, reveals an amplitude an annual average of the wave of hmed=1.53 m, obtained by taking maximum envelope appeared in a measurement range of 120 seconds. We compare these off-shore values with the coastal ones and we conclude that the wave’s energetic off-shore potential is unexpectedly bigger that in the coastal region.
The JUPITER Trial: Results, Controversies, and Implications for Prevention

Statin therapy is effective at reducing cardiovascular event rates among those with prior myocardial infraction, stroke, diabetes, or overt hyperlipidemia, and current guidelines strongly recommend lipid-lowering therapy among these patient groups as an adjunct to aggressive lifestyle interventions. However, of the nearly 1.7 million heart attacks and strokes that occur annually in the United States, more than half occur among apparently healthy men and women with average or low levels of cholesterol. Thus, novel screening and treatment strategies for cardiovascular prevention are needed that can detect high vascular risk in the absence of hyperlipidemia, that are inexpensive and simple to implement in the primary care setting, and that can provide comparable or superior effectiveness compared to currently accepted approaches. In a collaborative effort involving 1315 physicians in 26 countries, the JUPITER investigators1 sought to determine whether statin therapy might be effective at preventing first-ever cardiovascular events among men and women at risk for vascular disease because of elevated levels of the inflammatory biomarker high-sensitivity C-reactive protein (hsCRP) but who are not candidates for statin therapy under accepted guidelines because of low-density lipoprotein cholesterol (LDLC) levels less than 130 mg/dL, the current treatment target for primary prevention. JUPITER was a formal hypothesis testing trial based on prior observations that (1) inflammation plays a crucial role in atherogenesis2; (2) that the inflammatory biomarker hsCRP independently predicts vascular events and improves global classification of risk regardless of LDLC level3–6; (3) that statin therapy reduces hsCRP in a manner largely independent of LDLC reduction7,8; (4) that in acute coronary syndrome as well as stable patients, the magnitude of benefit associated with statins relates in part to achieved levels of hsCRP9–11; and (5) that in a previous hypothesis generating analysis of the AFCAPS/TexCAPS trial, no clinical …
Extracting the Unextractable: A Case Study on Verb-particles

This paper proposes a series of techniques for extracting English verb--particle constructions from raw text corpora. We initially propose three basic methods, based on tagger output, chunker output and a chunk grammar, respectively, with the chunk grammar method optionally combining with an attachment resolution module to determine the syntactic structure of verb--preposition pairs in ambiguous constructs. We then combine the three methods together into a single classifier, and add in a number of extra lexical and frequentistic features, producing a final F-score of 0.865 over the WSJ.
The mobile vision mixer: a mobile network based live video broadcasting system in your mobile phone

Mobile broadcasting services, allowing people to stream live video from their cameraphones to viewers online, are becoming widely used as tools for user-generated content. The next generation of these services enables collaboration in teams of camera operators and a director producing an edited broadcast. This paper contributes to this research area by exploring the possibility for the director to join the camera team on location, performing mixing and broadcasting on a mobile device. The Mobile Vision Mixer prototype embodies a technical solution for connecting four camera streams and displaying them in a mixer interface for the director to select from, under the bandwidth constraints of mobile networks. Based on field trials with amateur users, we discuss technical challenges as well as advantages of enabling the director to be present on location, in visual proximity of the camera team.
Formation of Eutectic Carbides in the Structure of High-Purity White Cast Iron in the Forging Process

It is found that the deformation of white cast iron under forging production is only possible with a minimum number of permanent impurities. The developed modes of high-temperature intermediate annealing facilitate the deformation of the forging under normal production conditions. It is shown that in the process of isothermal annealing of white cast iron begins the process of disintegration of ledeburite in the more stable eutectic carbides, providing technological plasticity for subsequent forging. The installed influence of the purity of white cast iron on the morphology of the excess carbides and their ability to divide. Studies the morphology of the excess eutectic carbides after melting, pre-annealing and after deformation forging. Discovered that after severe plastic deformation the structure of white cast iron becomes more stable, due to the appearance of eutectic carbides. It was determined that the deformed structure of white iron, because of its lack ledeburite component, was more identical with the structure of the alloy ledeburite steels. The data obtained can be used for making Damascus bladed weapons products, experiencing shock-variables loads.
A Laboratory Test Setup for in Situ Measurements of the Dielectric Properties of Catalyst Powder Samples under Reaction Conditions by Microwave Cavity Perturbation: Set up and Initial Tests

The catalytic behavior of zeolite catalysts for the ammonia-based selective catalytic reduction (SCR) of nitrogen oxides (NOX) depends strongly on the type of zeolite material. An essential precondition for SCR is a previous ammonia gas adsorption that occurs on acidic sites of the zeolite. In order to understand and develop SCR active materials, it is crucial to know the amount of sorbed ammonia under reaction conditions. To support classical temperature-programmed desorption (TPD) experiments, a correlation of the dielectric properties with the catalytic properties and the ammonia sorption under reaction conditions appears promising. In this work, a laboratory test setup, which enables direct measurements of the dielectric properties of catalytic powder samples under a defined gas atmosphere and temperature by microwave cavity perturbation, has been developed. Based on previous investigations and computational simulations, a resonator cavity and a heating system were designed, installed and characterized. The resonator cavity is designed to operate in its TM010 mode at 1.2 GHz. The first measurement of the ammonia loading of an H-ZSM-5 zeolite confirmed the operating performance of the test setup at constant temperatures of up to 300 °C. It showed how both real and imaginary parts of the relative complex permittivity are strongly correlated with the mass of stored ammonia.
The Collaborative Longitudinal Personality Disorders Study: reliability of axis I and II diagnoses.

Both the interrater and test-retest-retest reliability of axis I and axis II disorders were assessed using the Structured Clinical Interview for DSM-IV Axis I Disorders (SCID-I) and the Diagnostic Interview for DSM-IV Personality Disorders (DIPD-IV). Fair-good median interrater kappa (.40-.75) were found for all axis II disorders diagnosed five times or more, except antisocial personality disorder (1.0). All of the test-retest kappa for axis II disorders, except for narcissistic personality disorder (1.0) and paranoid personality disorder (.39), were also found to be fair-good. Interrater and test-retest dimensional reliability figures for axis II were generally higher than those for their categorical counterparts; most were in the excellent range (> .75). In terms of axis I, excellent median interrater kappa were found for six of the 10 disorders diagnosed five times or more, whereas fair-good median interrater kappa were found for the other four axis I disorders. In general, test-retest reliability figures for axis I disorders were somewhat lower than the interrater reliability figures. Three test-retest kappa were in the excellent range, six were in the fair-good range, and one (for dysthymia) was in the poor range (.35). Taken together, the results of this study suggest that both axis I and axis II disorders can be diagnosed reliably when using appropriate semistructured interviews. They also suggest that the reliability of axis II disorders is roughly equivalent to that reliability found for most axis I disorders.
Antibody response in pig nasal fluid and serum following foot-and-mouth disease infection or vaccination

SUMMARY Nasal fluid and serum collected from pigs after exposure to live foot and mouth disease (FMD) virus or injection of single oil emulsion (w/o) or double oil emulsion (w/o/w) vaccines were examined for FMD neutralizing activity. After virus exposure the response profiles of serum and nasal mucus were similar to one another. In both, neutralizing activity rose to a peak at one to two weeks after exposure and then subsided slowly. After vaccination with either the w/o or w/o/w preparations a neutralizing response was demonstrable in the serum three to seven days after the first injection, and this was boosted by revaccinations 56 and 117 days later. The neutralizing activity was also detectable in nasal fluid seven days after the first vaccination, but subsequent revaccinations 56 and 117 days later provoked neutralizing titres which were no greater than those observed after the initial vaccination.
Querying Encrypted XML Documents

This paper proposes techniques to query encrypted XML documents. Such a problem predominantly occurs in "database as a service" (DAS) architectures, where a client may outsource data to a service provider that provides data management services. Security is of paramount concern, as the service provider itself may be untrusted. Encryption offers a natural solution to preserve the confidentiality of the client's data. The challenge now is to execute queries over the encrypted data, without decrypting them at the server side. In this paper we develop: 1) primitives using which a client can specify the sensitive parts of the XML documents; 2) mechanisms to map the XML documents to encrypted representation that hides sensitive portions of the documents; and 3) techniques to run SPJ (selection-projection-join) queries over encrypted XML documents. A strategy, where indices/ancillary information is maintained along with the encrypted XML documents is exploited, which helps in pruning the search space during query processing
Robot-Aided Mapping of Wrist Proprioceptive Acuity across a 3D Workspace

Proprioceptive signals from peripheral mechanoreceptors form the basis for bodily perception and are known to be essential for motor control. However we still have an incomplete understanding of how proprioception differs between joints, whether it differs among the various degrees-of-freedom (DoFs) within a particular joint, and how such differences affect motor control and learning. We here introduce a robot-aided method to objectively measure proprioceptive function: specifically, we systematically mapped wrist proprioceptive acuity across the three DoFs of the wrist/hand complex with the aim to characterize the wrist position sense. Thirty healthy young adults performed an ipsilateral active joint position matching task with their dominant wrist using a haptic robotic exoskeleton. Our results indicate that the active wrist position sense acuity is anisotropic across the joint, with the abduction/adduction DoF having the highest acuity (the error of acuity for flexion/extension is 4.64 ± 0.24°; abduction/adduction: 3.68 ± 0.32°; supination/pronation: 5.15 ± 0.37°) and they also revealed that proprioceptive acuity decreases for smaller joint displacements. We believe this knowledge is imperative in a clinical scenario when assessing proprioceptive deficits and for understanding how such sensory deficits relate to observable motor impairments.
Promoting Access to White Rose Research Papers Sheffield University Clef 2000 Submission -bilingual Track: German to English

We investigated dictionary based cross language information retrieval using lexical triangulation. Lexical triangulation combines the results of different transitive translations. Transitive translation uses a pivot language to translate between two languages when no direct translation resource is available. We took German queries and translated then via Spanish, or Dutch into English. We compared the results of retrieval experiments using these queries, with other versions created by combining the transitive translations or created by direct translation. Direct dictionary translation of a query introduces considerable ambiguity that damages retrieval, an average precision 79% below monolingual in this research. Transitive translation introduces more ambiguity, giving results worse than 88% below direct translation. We have shown that lexical triangulation between two transitive translations can eliminate much of the additional ambiguity introduced by transitive translation.
Dementia-Specific Assisted Living: Clinical Factors and Psychotropic Medication Use

BACKGROUND: Assisted living (AL) is an increasingly popular long-term care alternative for older adults with dementia, making this setting an important focus for both clinical practice and research among psychiatric nurses. OBJECTIVES: This article describes results from a pilot study focusing on residents' cognitive and emotional status as well as psychotropic drug use. Findings are compared to reports from larger studies in the literature. STUDY DESIGN: A descriptive, correlational design was used to collect data from 17 residents in two dementia-specific AL facilities. RESULTS : Thirty-one psychiatric diagnoses were identified for 17 participants. Anxiety and depression symptoms were endorsed by more than 50% of participants, and 88% were prescribed psychotropic medications. CONCLUSIONS: AL residents may experience problems with cognition and emotional symptoms such as anxiety and depression, creating important roles for psychiatric nurses in staff education, promotion of nonpharmacologic interventions, and monitoring of psychotropic medication use in this growing population.
