By kinetic and dynamics analysis of the material conveyed by chain-belt feeder,the maximum material transportation height as well as the material transportation heights at different chain speeds were gained,and the factors affecting the transportation capacity of chain-belt feeder and the mathematical model were determined. The relationship between the transportation capacity of the chain-belt feeder and the chain speed was analysed by actual application. It is concluded that there is an optimal chain speed which can bring about the maximum transportation capacity,which provides theoretical foundations for the design of the chain-belt feeder.


Ever since the "living fossil", Metasequoia glyptostroboides, was discovered during the 1940s in China, accounts of its mysterious discovery and introduction throughout the world have been told many times in different languages. However, information has often departed considerably from the true story. This paper represents a synthesis of more than 1000 original letters, manuscripts and publications both in Chinese and other languages, and addresses two main questions about details of the story: (1) how was the living fossil really discovered, and (2) who introduced the seeds into the U.S.A. and the rest of the world? Several controversies surrounding the course of events are revisited. An appendix summarizes the names and academic positions held by botanists who played a key part in the tree's discovery.


Automatic text generation techniques with either extractive-based or generative-based methods are becoming increasingly popular and widely used in industry. In contrast to existing extractive-based text generation approaches that ignore the text coherence, our proposed approach integrates both keyword coverage and text coherence into our optimization framework. In this paper, we employ the semantics-based coherence and syntax-based coherence metrics to evaluate the text coherence. Extensive experiments on a real corpus demonstrate that our method outperforms baselines overall regrading ROUGE and Human evaluation metrics. Our model provides new insights on how to utilize coherence measures to arrange the sentences extracted by keyword covering method. The proposed method has been deployed on a real system to help generate coherent text.


Abstract : After undertaking research to determine the influence of weather on replenishment and carrier operations, it became apparent that deficiencies in the data concerning ocean wave characteristics exist. Before any substantial progress in the study of replenishment and carrier operations can be made, improved and standardized ocean wave observations must be available. This report is written primarily for quartermasters who are generally responsible for the observing and reporting of ocean waves aboard U.S. Navy ships. It presents, in a concise form, the characteristics of ocean waves and explicitly points out the differences between wind waves and swell. Standard methods for observing wave direction, period, and height are then presented.

Thin-film perovskite-based photovoltaics has great potential to make an important contribution to the ongoing search for new sources of clean renewable energy. Excitation of localized surface plasmons in metal nanoparticles could establish a new route for an improvement of the performance of such devices. Using the tools of electrodynamics (Lorenz–Mie theory adopted for absorbing host media), we predict a strong red shift in the spectral activity of gold and silver nanospheres and modification (negative or positive) of white and solar light harvesting in the film of perovskite host caused by centrally distributed plasmonic nanospheres. The enhancement of absorption in perovskite host is proven to be possible for photons with energies close to or smaller than the energy band gap in perovskite, with the final effect depending on the diameter of nanospheres, their concentration, and kind of metal. From the electronic band structure point of view, the predicted strengthening of absorption can be interpreted a...

The extracellular matrix (ECM) contains rich biological cues for cell recruitment, proliferationm, and even differentiation. The osteoinductive potential of scaffolds could be enhanced through human bone marrow mesenchymal stem cell (hBMSC) directly depositing ECM on surface of scaffolds. However, the role and mechanism of human umbilical cord mesenchymal stem cells (hUCMSC)‐secreted ECM in bone formation remain unknown. We tested the osteoinductive properties of a hUCMSC‐secreted ECM construct (hUCMSC‐ECM) in a large femur defect of a severe combined immunodeficiency (SCID) mouse model. The hUCMSC‐ECM improved the colonization of endogenous MSCs and bone regeneration, similar to the hUCMSC‐seeded scaffold and superior to the scaffold substrate. Besides, the hUCMSC‐ECM enhanced the promigratory molecular expressions of the homing cells, including CCR2 and TβRI. Furthermore, the hUCMSC‐ECM increased the number of migrated MSCs by nearly 3.3 ± 0.1‐fold, relative to the scaffold substrate. As the most abundant cytokine deposited in the hUCMSC‐ECM, insulin‐like growth factor binding protein 3 (IGFBP3) promoted hBMSC migration in the TβRI/II‐ and CCR2‐dependent mechanisms. The hUCMSC‐ECM integrating shRNA‐mediated silencing of Igfbp3 that down‐regulated IGFBP3 expression by approximately 60%, reduced the number of migrated hBMSCs by 47%. In vivo, the hUCMSC‐ECM recruited 10‐fold more endogenous MSCs to initiate bone formation compared to the scaffold substrate. The knock‐down of Igfbp3 in the hUCMSC‐ECM inhibited nearly 60% of MSC homing and bone regeneration capacity. This research demonstrates that IGFBP3 is an important MSC homing molecule and the therapeutic potential of hUCMSC‐ECM in bone regeneration is enhanced by improving MSC homing in an IGFBP3‐dependent mechanism.

It is known that in the first approximation, many real-life stationary stochastic processes are well-described by an exponential covariance kernel C(u) = exp(−a · |u|). Empirical evidence shows that in many practical situations, a good second approximation is provided by the modified exponential covariance kernel C(u) = exp(−a · |u|) ·(1−r · |u|). In this paper, we provide a theoretical explanation for this empirical phenomenon. 1 Formulation of the Problem How to describe a general stochastic process. Physical quantities change with time. A natural description of this change, a description that takes into account that future values cannot be exactly predicted, is a description by a stochastic process; see, e.g., [5]. In many practical situations, while the quantities themselves change, the rules that describe these changes remain the same. Such situations are described by stationary processes. A general stationary stochastic process S(t) can be reduced to a zero-mean unit-variance process X(t) by an appropriate linear transformation


Due to the complex and subjective nature of odour perception, estimating the impact of pollutant sources on the community requires the use of multiple tools. Currently, the European standard EN 16841:2016 - Part 1 describes a technique to evaluate odour in ambient air through sniff testing called the grid method, useful to build datasets comparable with dispersion modelling results. Another methodology to assess the exposure to offensive odours is based on the active participation of the affected community. In the Czech Republic, the AirQ system is being used to collect the complaints of voluntary subjects residing nearby problematic sources. Nevertheless, for this application to give meaningful information, the data has to be cross-checked against wind direction and validated using near-real time output of a dispersion model. The presented study aimed to evaluate the performance of Lagrangian models AUSTAL and GRAL, and Czech Gaussian model SYMOS by using the field inspection dataset gathered in a pig-fattening farm located in Styria (Austria), and the output of the AirQ system in the vicinity of a feed production industry in the city of Prague. Results show the importance of an appropriate selection of the peak-to-mean factor and provide relevant knowledge for the future consideration of the most suitable dispersion model for odour assessment in the Czech Republic.


Fast cooling of beef carcasses has an important effect on reducing color instability in the deep muscles of the carcass. A numerical simulation of beef carcass chilling was done by using a digital scan of beef carcass geometry and measured values of flow properties. The scanning process and measurement were conducted in an industrial chiller to obtain realistic working condition for the simulation input. Simulation of 60h chilling was performed for a single and multiple carcasses. Simulation results were validated with measurements and the effect of flow direction on the cooling rate was analyzed. INTRODUCTION After slaughter, meat undergoes various biochemical and physiological changes which leads to quality degradation of the product. The rate of these changes can be controlled by fast chilling of the beef carcass. Color instability which is usually observed in the internal part of the beef carcass occurs due to the biochemical and physiological changes taking place in meat at high temperature and relatively low pH (James and James, 2002). Fast cooling of the internal parts of beef carcasses just after slaughter has been shown to be beneficial in maintaining color stability and a more stable product. The rate of cooling depends on cooling air properties like temperature, humidity, air velocity and turbulence as well as carcass geometric properties such as size and shape. Apart from experiments, optimization of carcass cooling can also be done using CFD. Trujillo and Pham (2006) and Pham et al. (2009) presented a CFD modeling approach with RNG low-Reynolds number wall treatment to predict the convective air cooling of a single beef carcass using a 3D geometrical model assembled from cross sectional images. Mirade and Picgirard (2001) showed that CFD can be used to optimize airflow distribution in carcass cool rooms and used simplified carcass geometries to perform large scale computations. In this study, air flow measurements of cooling air were conducted in an industrial beef carcass chiller and the carcass geometry was obtained using 3D surface scanning. This information was used to provide realistic input for the numerical simulations. Carcass temperatures at different positions and depths were measured for validating the simulation result. The aim of this contribution was to see the effect of flow directions on cooling rate of multiple beef carcasses using a CFD model with a realistic carcass geometry obtained from a laser scan, and to compare with a single carcass. MATERIALS AND METHODS Measurements Air velocities were measured with an ultrasonic anemometer (Gill WindMaster, Gill Instruments Ltd, Hampshire, England) at 32 Hz sampling rate at 8 different positions around the carcass to obtain velocity and turbulence intensity values, in order to determine realistic boundary conditions of the computational domain (Fig.1b). Carcass temperatures were measured on leg and rib locations at different depth for about 72h with thermometers connected to data loggers. The humidity and temperature of the air were measured, for the same duration, with humidity sensors having data logging facility. Modeling and Simulation A digital model of the carcass was obtained using a high-resolution 3D laser scanning system (K-Scan, Nikon Metrology, Belgium), capturing the specific body characteristics of the carcass (Fig.1a). From the 3D virtual carcass model, computational domains with dimension of ( 18 m X 8 m X 5.5 m) were developed by ANSYS Design Modeler for single and multiple carcasses. Unstructured meshing of 1.8 and 2.5 million elements for single and multiple carcass computational domains respectively was done by ANSYS ICEM CFD. CFD computations were performed in parallel with ANSYS CFX on a 12-core 2.66GHz 48GB RAM PC. The measured cooling air average velocity(0.58ms^-1), temperature(2.3°C), relative humidity(100%) and turbulence intensity at measurement points were used as model input for the simulation. Measured carcass temperatures were used for validation of experimental values with the simulation results. The cooling of beef carcass is achieved by heat exchange with the environment, i.e. the cooling media (air) surrounding it. This heat is transported through the carcass by conduction and then removed at the surface by convection, evaporation and radiation. The process involves the transfer of heat (and mass) from the carcass surface. The heat balance at the carcass surface can be expressed as: , , ( ) ( ) s w T w Ta m c s a v s a a P rhP h T k h T T L n R T T         -----------(1) with the surface heat transfer coefficient (W m -2 K -1 ), Ta the air temperature (K), Ts the surface temperature, σ the Stefan-Boltzmann constant ( 5.67×10 -8 W m -2 K -4 ), ε the emissivity, hm the surface mass transfer coefficient (m s -1 ), R the specific gas constant for water (J kg -1 K -1 ), rh the relative humidity, Pw vapor pressure of water (Pa), a the water activity of carcass surface, Lv the latent heat of vaporization (J kg -1 ) and k the thermal conductivity of the meat (W m -1 °C -1 ). Inside the beef carcasses (solid domain) the heat transport equation was solved while in the air domain a set of five transport equations (continuity, momentum, heat, turbulent kinetic energy and turbulent dissipation) were solved. At the interface between the solid and the fluid domains the energy flux lose due to evaporation, the second term on the right of equation (1), was included as an energy source for fluid domain. A constant value of the water activity was used in the expression. Heat lose by radiation was not included in the simulation as net radiation energy transfer from one carcass to the other carcass is negligible. For rows of carcasses exposed to the walls of the chilling room this effect may not be negligible during the initial hours of chilling as the wall temperature is lower than the carcass temperature. The convective heat transfer is directly calculated by the software based on flow properties and the geometric shape. Obtaining a realistic geometry therefore helps in calculating convective heat transfer, and the convective heat transfer coefficient, more accurately. For the turbulence modeling, Reynolds-averaged Navier-Stokes (RANS) with the shear stress transport (SST) k-ω model was used (Delele et al., 2008). RESULTS AND DISCUSSION Figure 2b, presenting results for a single carcass, shows that the carcass sides cool faster around the ribs as compared to the leg part due to the difference in thickness of each part. On the same figure, during the initial hours of chilling the measured temperature profile increase in the leg but not in the rib. There is more glycogen storage at legs than at ribs, which contributes to heat production in beef muscle during rigor mortis (James and C.James, 2002), which will be thus more pronounced in the thicker parts. Future models should take this heat production into account. Figures 3b and 4b indicate that at the working conditions of the considered industrial chiller, the flow direction doesn't have a considerable effect on the rate of cooling. This can be due to the fact that the conductive heat transfer is mainly controlling the rate of cooling. This is evident from the ratio of the heat transfer resistances inside the carcass to the surface of the carcass (Biot number) which is much larger than 1. Measured cooling air velocity and calculated turbulence intensity at the measurement points around the carcass is shown on figure 5.

This diachronic analysis of narrative in Old and Middle English texts from the eighth to fifteenth centuries builds upon recent cognitive explorations in both medieval literature and narratology to identify and contrast certain enduring themes in OE and ME visionary texts. In attending to the evolution of conceptions of the self, and each conception's embeddedness in the social imaginary of a place and time, multi-layered new readings emerge of the Old English poems The Dream of the Rood, and Guðlac A and Guðlac B (in addition to the prose Life of St Guðlac); and the Middle English poems St Erkenwald; Pearl; and Piers Plowman. While previous studies have noted the importance of society to the role of the fourteenth-century 'public poet', this analysis proposes a much earlier, enduring link between medieval narratives of dream, visions, and marvels; the thinking, speaking self; and the larger social imaginary. The application of extended cognition to envisioned people, objects, and environments in poetic English narrative moves critical discussion beyond the formation of the dream-vision genre, toward an awareness that medieval authors could treat any environment as more or less imagined and sense-bearing. As the worked examples demonstrate, destabilisation of social structures is reflected in the disorganisation of these envisioned environments. Individual focalisation both 'personalises' these stresses and attempts to articulate a new, stable environment through reorganisation of elements of the social imaginary.

Patients with Alzheimer's disease as well as those with lower limb paralysis often suffer from varying degrees of urinary incontinence. In this work, an ultrasonic-based bladder urine volume detection device was developed, in which the urine volume can be measured in vitro. The ultrasonic transmitting circuit and ultrasonic receiving circuit were designed and developed. The characteristics of bladder expansion were analyzed, and the pinhole camera model was designed for detecting urine volume, moreover, the bladder height model was proposed to calculate the bladder urine volume. The effectiveness of the hardware circuit is verified by the function test of the ultrasonic transmitting circuit and receiving circuit. Finally, the biological tissue experiment and simulated bladder experiment were carried out to verify the feasibility and effectiveness of the device for measuring bladder urine volume.


Perfusion culture is an effective method to enhance the oxygen and nutrient mass transfer for the culture of highly metabolic cells and/or the culture at a high cell density. However, the flow rate of culture medium induces a shear stress that may lead to the death of cells if it is too high. In this study, we measured the cellular adhesion ratio on various materials coated with type-I collagen under Poiseuille flow with flow rates in the range 1–21 mL/min. Hepatoma cell line, HepG2 cells, attached better on a polystyrene plate for tissue culture coated with type-I collagen (with τ0.5 , the shear stress required to detach 50% of cells, equal to 42.2 Pa) followed by a collagen coated glass plate (τ0.5 of 40.5Pa), then a polystyrene plate for tissue culture without collagen coating (τ0.5 of 33.8Pa), and finally on a PDMS (τ0.5 of 24.8Pa) plate coated with collagen. The fluorescence staining of the collagen suggests that clumps of cells and collagen were detached from the surface, which implies that the cell-collagen bonds are stronger than collagen-substrate bonds. Accounting these results, it can be concluded that by reinforcing the bonds between collagen and substrate, it might be possible for the cellular monolayer to stay attached on the substrate until τ0.5 reaches ∼40Pa. This conclusion suggests the importance of carefully choosing the cell substrate, which has a strong binding with the coated extracellular matrix, for the cell culture under a high shear stress.Copyright © 2011 by ASME


IN early August I923 Sergei Esenin and Isadora Duncan returned to Moscow after their fifteen-month tour of Europe and the United States. The poet's relationship with Isadora, never very stable, had markedly worsened since about February I923. After a few days together in Moscow they quarrelled once again, and Esenin disappeared. Shortly afterwards, on 13 or 14 August, Isadora and her pupil Irma Duncan departed for the Caucasus, where Isadora was to dance and also recuperate. Esenin saw her off as she left Moscow by train, and even promised to come later to the Caucasus or Crimea but in fact this was the end of their life together. In late August Esenin wrote a letter to Isadora, which contains several lines persistently banned by the Soviet censor.1 In September I992 the present writer was at last allowed to see the original of this letter, which is held in the Central State Archive of Literature and Art, Moscow. As expected,2 the censored lines describe Esenin's meeting with Lev Trotskii, thus shedding light on the complex relationship between peasant poet and revolutionary leader. The theme of 'Esenin and Trotskii' has assumed particular urgency in the past four years, as controversy rages over the circumstances of Esenin's death.

Forecasters were right-the 2007 hurricane season, is an intense one. Hurricane Dean wrecked Antilles banana production. The plantations were hard-hit in both the French West Indies and the ACP countries in the zone, but these bananas should be back in European shops in February 2008. Demand is in a growing phase and alternative sources of supply are being sought. Both import and retail prices are rising. (Resume d'auteur)


Abstract : On the basis of zincborophosphate glasses with the observance of specific melting conditions it is possible to synthesize opaque and transparent glasses with an increased content of halogens up to 22 wt. percent NaCl, 24 wt. percent NaBr, and 17 wt percent NaJ. It is characteristic that in the four-component systems given at small quantities the ions of halogens and alkali metals yield opaque glasses, but with a further increase in the content of the ions of a halogen or alkali metals transparent glasses are formed. The increased content of ions of halogens also influences the temperature of softening, electroconductivity, thermal-expansion coefficient and others. (Author)

Polyesterimide resin applied for winding impregnation has been modified by incorporating the hydrophilic and hydrophobic nanosilica, montmorillonite and aluminium oxide. For assessment of the resins in liquid and cured states thermoanalytical methods TG/DSC were used. For pure and nanofilled resins the results of investigation of AFM topography, bond strength, dielectric strength and partial discharge resistance have been also presented. It was found that dielectric and mechanical properties of polyesterimide resin containing hydrophilic silica as well aluminium oxide were much improved as compared to pure resin. Based on our investigations we have found that the methods of thermal analysis may be very useful for evaluation of nanocomposites: DSC/TGA study of resins in the liquid state under dynamic conditions can be applied to pre-select nanocomposites; isothermal TG curves of cured resins can be utilized for thermal stability evaluation; in turn, TG study after thermal ageing of cured resins could confirm the barrier properties of nanocomposites.

HOSE public nuisances who are variously described as T habitual criminals, hardened offenders, confirmed crimirials, or recidivists are, like the poor, ever with us ; and, like poverty, they present a problem which seems insoluble. From time to time attention has been concentrated on this type of offender, and then books have been written about him, Parliament and the appropriate public department have taken him into consideration, while the newspaper press has published correspondence discussing him. One such manifestation of interest in the culprit with confirmed criminal tendencies was recently seen. It began with a letter to The Times from the late Sir Arthur Conan Doyle, who expressed the view that the habitual criminal ought to be eliminated from society altogether. ' From the time that his true character is established, the prison doors should never open again.' Soon afterwards came the expression of opinion by Mr. Justice Horridge to the Grand Jury at Lewes Assizes that the aim should be ' to try to save the young offender and leave the law as regards the hardened criminal as it was.' Then came the resolution adopted by the Visiting Justices' Conference, asking the Secretary of State to appoint a Committee of Inquiry with wide terms of reference, to investigate the whole question of the treatment of habitual offenders. The daily average population of prisons and Borstal institutions in England and Wales was 11,109 in 1928. What proportion of these belonged to the stage army of old offenders who swell the statistics of ' receptions ' into prison is not known, but such figures as are available suggest that it is possible to get an exaggerated idea of the size of the recidivist


Abstract Uncontrollable bleeding is still the main cause of post-traumatic deaths due to the blood loss. Moreover, infectious complication of wound is also still a challenging problem for wound healing. Nevertheless, the currently available hemostasis drugs or materials cannot stanch bleeding well due to single function, slow in effectiveness, adhere to wounds easily, poor gas permeability, etc. Therefore, it is of a great significance to utilize a biomedical hemostatic material that can stop bleeding quickly, preventing from bacterial infections, and with good biocompatibility properties. Herein chitosan (CS) was modified with gallic acid (GA) and thrombin (TB) to prepare an antibacterial hemostatic composite dressing. The CS-based composite hydrogel dressing was obtained by acylation modification, ultraviolet curing crosslinking method and physical mixing. The in vitro results showed that our prepared CS-based composite hydrogel has obvious burst release and good degradation property. Moreover, the in vivo results showed that it has a strong antibacterial property that is much better than single CS, and it can stop bleeding in 1 min which can promote wound healing. Therefore, the findings of this study is expected to contribute to the future designing of biomedical hemostatic materials with improved properties.

A pulse are used for the ultrahigh-speed cross-correlation detection. Successful prescaled 6.3-GHz clock recovery from a 400-Gbls optical time division multiplexed signal is also presented using a cross-correlation between the 400 Gb/s optical signal and a 6.3 GHz, 1 ps, optical super-continuum clock pulse train. noise of the timing clock so extracted is related to the signal- to-noise ratio (SNR) of the electrical cross-correlation signal power (hereafter power,,) obtained by FWM light SNR (71.

In this paper, we present the design and implementation of an open-source reconfigurable very long instruction word (VLIW) multiprocessor system. This processor is implemented as a softcore on a field-programmable gate arrays (FPGA) and its instruction set architecture (ISA) is based on the Lx/ST200 ISA. This multiprocessor design is based on our earlier ρ-VEX processor design. Since the ρ-VEX processor is a parameterized processor, our multiprocessor design is also parameterized. By utilizing a freely available compiler and simulator in our development framework, we are able to optimize our design and map any application written in C to our multiprocessor system. This VLIW multiprocessor can exploit data level as well as instruction level parallelism inherent in an application and make its execution faster. More importantly, we achieve our results by saving expensive FPGA area through the sharing of resources. The results show that we can achieve two times better performance for our dual-processor system (with shared resources) compared to a uni-processor system or a 2-cluster processor system for applications having data level and instruction level parallelism.


More and more domestic college students are favor of the E-book reading at present, but the status quo of reading quality is poor. In response to this condition, the thesis, based on the paper questionnaire and the depth of interview, analyzes many significant factors of influencing reading quality with empirical research. It puts forward that the university library should start with enriching the collection of E-books and setting up a convenient platform to find and acquire E-books. Then the library should create a highly full-bodied reading atmosphere on the campus and building an E-book service platform that is in good quality. The measures mentioned above are quite effective ways to improve college students reading quality of E-books. Keywords—E-books; college students reading; college library;


This article examines the use of Virtual Reality (VR) technology in theatre and the new notions of performance, stage, theatrical apparatus and spectatorship that it entails. As witnessed over decades of multimedia theatre, today's theatre no longer solely depends on the bodies of live performers, and it increasingly draws on technological devices and digitally mediated networks to hint at potential posthuman alternatives to our age-old theatrical institution of live performers and spectators. In VR theatre, the prospect of posthuman spectators looms as the human body is aided by goggles or head-mounted displays (HMD) that function as prosthetic eyes. Digitally mediated images in theatre were previously considered to act as a Derridean supplement to the weak presence or complete absence of human bodies on stage, thus highlighting the prerequisite essentiality of live bodies. However, new technologies and media introduced in theatre emphasize the perception and bodily senses of spectators and how they, and not necessarily the live actors on stage, constitute the essence of performance. By reading A Theater for an Individualist (2020) as metatheatre on VR theatre, this article argues that such a format - which is often employed in VR performances - addresses how the act of watching has evolved in theatre, from a singular and linear experience to an alinear and plural one. The article concludes that the application of VR in theatre actually could support and even extend the agency of spectators, drawing on Jacques Rancière's discussion of oppositions - activity and passivity; individuality and community; ignorance and knowledge - in The Emancipated Spectator (2008).


In 1991, the 43-year-old female patient had an ITI implant incorporated alio loco regio 13 (Fig. 1). Exept for the remaining tooth 23, the superior maxilla is edentulous. After the healing-in process of the implant, a telescopic crown was placed onto the implant and the remaining tooth 23, onto which a telescopic prosthesis is fastened (Figs. 3, 4). After completion of the prosthetic phase, no recall took place because the patient moved away. Upon the recommendation of an acquaintance, the patient came back to our office in 1994 when she detected that brushing implant abutment 13 resulted in profuse bleeding. The clinical findings verified this observation. Probing with a pressurecalibrated plastic PA probe, BOP could be found and also there was a circular probing depth of 6 mm.


The vibration tests are essential part of environmental tests in reliability assurance procedures. Technical oriented high school students who take part in the reliability technician training course have not sufficient knowledge to understand the mathematical and physical theories of the tests. This paper proposes a practical way of education for even the high school students to get the concepts of the tests through hands on experiments. The visual experimental settings, smart-phones, Geogebra, and Ansys software were used to attract their interests and to effectively move their questions to the basic theories of the tests.


Numerous eruptive episodes with Strombolian activity, lava fountains, and lava flows occurred at Mt. Etna volcano between 2006 and 2013. In particular, there were seven paroxysmal lava fountains at the South East Crater in 2007-2008 and 46 at the New South East Crater between 2011 and 2013, while months-long lava emissions affected the upper eastern flank of the volcano in 2006 and 2008-2009. The monitoring of such volcanic phenomena is particularly relevant for their potential socio-economic impact in this densely populated volcanic region. For example, explosive activity has often formed thick ash clouds with widespread tephra fall able to disrupt the air traffic, as well as to cause severe problems at infrastructures, such as highways and roads. Early information about changes in the state of the volcano and/or at the onset of potentially dangerous eruptive phenomena requires efficacious surveillance methods. Several studies on seismic data recorded at Mt. Etna highlight that the analysis of the continuous background seismic signal, the so-called volcanic tremor, is of paramount importance to follow the evolution of volcanic activity (e.g., Alparone et al., 2003; Falsaperla et al., 2005; Langer et al., 2009). Indeed, changes in the state of the volcano as well as in its eruptive style are usually concurrent with variations of the spectral characteristics (amplitude and frequency) of tremor. This signal is recorded at Etna by means of the INGV seismic network equipped with broadband sensors. The huge amount of digital data continuously acquired by INGV's stations every day makes a manual analysis difficult. To overcome this problem, techniques of automatic classification of the tremor signal were applied to explore the robustness of different methods for the identification of regimes in volcanic activity (Langer et al., 2009). In particular, Langer et al. (2011) applied unsupervised classification techniques to the tremor data recorded at one station during seven paroxysmal episodes in 2007-2008. Their results revealed significant changes in the pattern classification well before the onset of the eruptive episodes. In the wake of this evidence, Messina and Langer (2011) developed KKAnalysis, a software that combines an unsupervised classification method (Kohonen Maps) with fuzzy cluster analysis. This tool was set up at the operative centre of the INGV-Osservatorio Etneo in 2010, and it is hitherto one of the main automatic alerting tools to identify impending eruptive events at Etna. The software carries out the on-


Virtual reality (VR) games construct an immersive context for the youth's entertainment and learning. VR game addiction (VAD) occurs simultaneously and brings about psychological issues. The current research employed a maximum likelihood estimation method to construct a structural equation model, by which learners' VR consumption behaviors were examined. The bootstrapping approach was adopted to explore further the mediation of VR realism (VRR) and the moderation of VR affordance on learners' VAD, which potentially leads to distressing behavioral and psychological circumstances. Data were collected from 575 students recruited in the survey, which was followed by a test of reliability and validity through confirmative factor analysis. Results concluded that VRR and consumers' cognitive satisfaction played a significant role as mediators while conceptualizing addictive behavior based on VR-perceived experience of consumers, self-efficacy, and interactivity. Moreover, this study conceptualized addictive behavior toward VR games through a structural equation model in a media-rich environment and suggested practical implications to reduce addictive behavior.


The main objective of this work is the development of a static reflectivity Doppler radar system from an existing system, introducing the necessary changes to achieve the desired application. The instrument that is proposed to be developed must be able to detect precipitation in the form of hydrometeors and save the data obtained in order to process and provide the necessary information for its subsequent characterization.


A cover mat for a vehicle window glass is provided to serve a frost free function in winter season and a prevention function for a rise in temperature in summer season. A cover mat(100) for a vehicle window glass comprises a front face intercepting film(110) for covering the front window glass of the vehicle, a magnetic member(120), a vacuum sucker(130), an extension portion(140) covering the cowl of a vehicle hood, and a sensor(150) for detecting a theft occurrence. The front face intercepting film includes a dual film consisting of a mesh(111) formed at one side of the cover mat and a pad(112) formed at the other side thereof. The magnetic member receives and seals the edges of the front face intercepting film such that the edges are attached to the respective parts of the vehicle. The vacuum sucker is disposed at lower side of the front face intercepting film to such that the film is detachably attached to the window glass.


Popular summer holidaymaking in the mainstream and much-visited destination of Mallorca is segmented and versatile in terms of tourist motivations. This study demonstrates unanimous touristic interest in pleasant weather conditions and a majority emphasis on sociability, relaxation, and beach life, along with cultural sightseeing and landscape experience motivations. Moreover, the findings indicate quite stable motivations in this holidaymaking context. There are very few motivational differences between Mallorca visitors using package tours or charter flights and their fellow tourists going by scheduled flights. The questionnaire-based survey results thus challenge conventional wisdom about Mediterranean seaside package tours as undifferentiated "sun and sand mass tourism" for "ordinary people" lacking individuality. Although air travel and package tours may still be standardized, the tourists themselves do not become homogenous simply by the mere utilization of such products.


We aimed to setup a noninvasive and well‐controlled methodology for evaluation of the cerebrovascular response in mice (C57BL/6J; 12 weeks). Therefore we applied a normo‐, hypo‐, and hyperventilation paradigm combined with arterial spin labeling and monitoring of the expired CO2 (expCO2) (n = 7) or arterial pCO2 (apCO2) (n = 12). Reducing the tidal volume by 25% and the respiratory rate by 20% resulted in hypercapnia (apCO2 from 33 ± 6 mmHg to 64 ± 16 mmHg). Increasing the respiratory rate by 25% and the tidal volume by 20% decreased apCO2 to 22 ± 5 mmHg. Cerebral blood flow (CBF) was 82 ± 21, 163 ± 41 and 64 ± 18 mL/100 g/min during normo, hypo‐, and hyperventilation, respectively (midbrain). The correlation of apCO2 and CBF levels resulted in a cerebrovascular response of 2.7 ± 0.3, 2.1 ± 0.3, 2.1 ± 0.3, and 3.7 ± 0.5 mL/100 g/min/mmHg for midbrain, cortex, hippocampus and thalamus, respectively. As expCO2 levels were correlated with apCO2 (r2 = 0.86; n = 4) and CBF (r2 = 0.67) a cerebrovascular response based on simultaneously recorded CBF and expCO2 levels could be derived (3.3 ± 0.5, 2.5 ± 0.4, 3.0 ± 0.4, and 4.5 ± 0.6 mL/100 g/min/mmHg; order as above). A cross‐over experiment resulted in similar responses. In conclusion, this protocol allows evaluating basal CBF and cerebrovascular response in mice under well‐controlled conditions by simply changing ventilator settings and correlating CBF with apCO2 and/or simultaneously obtained expCO2.

The paper presents the research results on the dynamic load resistance of ceramic matrix composites with aluminum spatial skeleton reinforcement, particularly focused on the ability to absorb impact energy. In the considered cases, the composite composition was complemented with a liquid additive. The addition was designed to improve impact energy absorption. The matrix of the composite was simultaneously a foundry core of skeleton casting. Internal channels which reproduce i trusses were created with the use of specially designed templates. The use of ceramic shapes allowed the authors to obtain strong cores with complex geometry, which act at the same time as the composite matrix, influencing its mechanical properties. Strength tests with a dynamic load were performed. The energy absorbed by the composite material was determined. The research was conducted on a specially-designed stand. The concept of the stand was developed based on drop weight tests.


The paper is focused on a development of a feedback-based architecture for successive-approximation time-to-digital converter (SA-TDC). The adoption of the feedback-based rather than feedforward architecture for the n-bit SA-TDCs is inspired by the classic successive approximation voltage-to-digital converter and motivated by a possible reduction of the number of time comparators from n to one. Nevertheless, existing developments of the feedback-based SA-TDC are characterized by much longer conversion time than that for feedforward SA-TDCs. In the paper, a concept of the feedback-based SA-TDC with dynamic equalization of logic propagation delays in the feedback loops is presented. The use of this technique allows to maintain the conversion time of the feedback-based SA-TDC the same as for the feedforward SA-TDC with just a single time comparator.

A novel Frequency Selective Surface (FSS) is proposed for the design of polarization-insensitive metamaterial absorbers that operate around 1 GHz, where the first resonances of small commercial enclosures take place. The novel FSS is based on the simplification of an alternative Roman maze. It shows a strong sub-wavelength response and is promising for the design of compact planar absorbers with excellent angular and polarization stability.


The article describes the morphological features and mineral composition of two amethyst geodes from the exposition of Moscow State University's mineralogical gallery "Nature's Art in Stone", based on the Primo Rovis collection. The article presents data from the studies of the phase composition of the geodes by powder X-ray diffraction (XRD) and micro X-ray spectral (XRD) analyses, and contains microphotographs. The mechanism of mineral phase crystallization of the described geodes is proposed.


Resisting Arsenic The discovery of a bacterium living in the extreme conditions of Mono Lake, California, created a major controversy because it was claimed to be able to grow solely on arsenic and could substitute arsenate for phosphate in its key macromolecules, including DNA. Working with the same Halomonas spp. bacterium, known as GFAJ-1, and ultrapure reagents, Erb et al. (p. 467) found that the bacterium needed a low level of phosphate (1.6 µM) to grow at all. Rather than significant specific arsenic incorporation, when the organism was grown in 40 mM arsenic, its nucleic acids acquired a trace of arsenic. Similarly, Reaves et al. (p. 470) found that GFAJ-1 could not grow in the absence of phosphate and, moreover, that its growth was not stimulated by the addition of arsenate, although a trace amount of arsenic was also detected in DNA. Thus, GFAJ-1 shows no particular facility to substitute arsenic for phosphate, when phosphate is limiting, but it can tolerate high concentrations of the poison while efficiently scavenging phosphate. Claims of arsenic substitution for phosphorus in the biomolecules of a Mono Lake bacterium are not independently reproduced. A strain of Halomonas bacteria, GFAJ-1, has been claimed to be able to use arsenate as a nutrient when phosphate is limiting and to specifically incorporate arsenic into its DNA in place of phosphorus. However, we have found that arsenate does not contribute to growth of GFAJ-1 when phosphate is limiting and that DNA purified from cells grown with limiting phosphate and abundant arsenate does not exhibit the spontaneous hydrolysis expected of arsenate ester bonds. Furthermore, mass spectrometry showed that this DNA contains only trace amounts of free arsenate and no detectable covalently bound arsenate.


A study concerning the incorporation of sepiolite in blends of biopolyesters (PHBV/PLA) to obtain clay/polymer nanocomposites (CPN) was performed to improve the gas barrier performance of the final materials and achieve a well dispersed morphology by means of an increase in the melt viscosity during melt blending. The latter is relevant to increase the stability of the PHBV sheets during thermoforming. The samples were analyzed using scanning electron microscopy (SEM), wide angle X-ray diffraction (WAXS), thermogravimetric analysis (TGA), differential scanning calorimetry (DSC), tensile tests at room and high temperatures, dynamo-mechanical thermal analysis in torsion mode (DMTA), oscillatory rheometry with a parallel plate setup, Vicat softening temperature system and oxygen barrier properties. The resulting Sepiolite/PHBV/PLA nanocomposites not only improved the compatibility between the biopolymers and reduced the oxygen permeability, but also improved the mechanical properties at room temperature, showing an increase in the elongation at break, as well as increasing the rigidity and stability of the CPN at higher temperatures, which could make them very attractive for uses in thermoforming applications for food packaging.

We developed a method to construct three-dimensional (3D) tissues that mimic in vivo-like hierarchic structures with different cell-densities using "cell-bead method" (Fig. 1). To construct the 3D structure, we prepared monodisperse collagen type-I gel beads by using an axisymmetric flow-focusing device (AFFD), and obtained two types of cell beads with different size: neonatal human epidermal keratinocyte (NHEK) beads and neonatal human dermal fibroblast (NHDF) beads. We then molded the NHDF beads and the NHEK beads subsequently into a polydimethylsiloxane (PDMS) chamber. After 24-hour incubation, we successfully obtained 3D tissues having in vivo-like hierarchic structure of the NHEK cells and the NHDF cells with different cell density. And tissue remodeling was observed in the reconstructed 3D tissue. We believe that the in vivo-like 3D skin tissue models are useful as the alternatives to animal testing in cosmetics, pharmadology and so on.


The Viimsi peninsula is located north-east of Tallinn, capital of Estonia. The Cambrian-Vendian (Cm-V) aquifer system is a sole source of drinking water in the area. Historically, the groundwater exploitation has led to freshening of groundwater in the peninsula, but in recent years an increase in chloride concentrations and enrichment in δ18O values has been detected, but in recent years hydrochemical parameters indicate an increasing influence of a saline water source. The exact origin of this saline water has remained unclear. The aim of the current study is to elucidate whether the increase in Cl− concentrations is related to seawater intrusion or to the infiltration of saline water from the underlying crystalline basement. To identify the source of salinity, chemical composition of the groundwater and the isotope tracers (e.g., δ18O and radium isotopes) were studied in the Viimsi peninsula in the period from 1987 to 2018. Our results show that chemical composition of Cm-V groundwater in the peninsula is clearly controlled by three-component mixing between glacial palaeogroundwater, saline water from the underling crystalline basement and modern meteoric water. The concentrations of Ra are also significantly affected by the mixing, but the spatial variation of radium isotopes (226Ra and 228Ra) suggests the widespread occurrence of the U in the surrounding sedimentary sequence. Our hypothesis is that, in addition to U originating from the crystalline basement, some U could be associated with secondary U deposits in sedimentary rocks. The formation of these secondary U deposits could be related to glacial meltwater intrusion in the Pleistocene. Although the results suggest that the infiltration of saline groundwater from the underlying crystalline basement as the main source of salinity in the study area, the risk of seawater intrusion in the future cannot be ruled out. It needs to be highlighted that the present groundwater monitoring networks may not be precise enough to detect the potential seawater intrusion and subsequent changes in water quality of the Cm-V aquifer system in the Viimsi peninsula.


FN-y is a cytokine of great clinical significance. The excessive or insufficient function of the signalling pathway triggered by IFN-y is a cause of various pathological states of the immune system and the body in general. At present, clinical practice uses quantitative methods of detection of this protein without taking into account its functional activity. Traditional tests for assessment of the biological activity of IFN-y are technologically complex and their results are poorly quantified. In the course of this work a model system was created representing a cell line with a reporter construct stably integrated into the genome controlled by a STAT-dependent promotor. Processing of the cells of this model system by IFN-y activates the STAT-1-signalling pathway, which causes expression of FFly luciferase gene. Luciferase activity is quantitatively assessed by detection of bioluminescence. Working concentration values (2.5 ng/ml) and time of performing the assay (8 h) were chosen. The effectiveness of using the model system for testing IFN-y bioactivity has been shown.


In this paper we analyse the stability of black hole Cauchy horizons arising in a class of 2d dilaton gravity models. It is shown that due to the characteristic asymptotic Rindler form of the metric of these models, time dependent gravitational perturbations generated in the external region do not necessarily blow-up when propagated along the Cauchy horizon. There exists, in fact, a region of nonzero measure in the space of the parameters characterizing the solutions such that both instability and mass inflation are avoided. This is a new result concerning asymptotically flat space-times, not shared by the well-known solutions of General Relativity. Despite this fact, however, quantum back-reaction seems to produce a scalar curvature singularity there.


In order for object detection and tracking in videos obtained from unmanned aerial vehicles (UAVs) by deep convolutional neural networks (DCNN), extensive ground truth optical flow, occlusion and segmentation datasets, of various objects or vehicles, are required during the training and testing processes. The mentioned ground truth informations are not widely available in the literature due to the difficulty of labeling or extracting them from real-life recorded UAV video images. In this study, ground truth optical flow, occlusion and segmentation datasets were produced synthetically for the first time with the UAV point of view in a novel way, so as to fill the gap in literature. The ground truth datasets were created for each vehicle by subjecting the triangles (mesh) automatically generated by the Unity engine to the homography method. With this method, 1920x1080 and 250x250 sized synthetic datasets consisting of 100 scenarios were obtained.


The Old Town of Lijiang has a long history and the style of simple nature combining the flavor of water village and the appearance of mountain city.After eight centuries construction by Naxi people,the spatial layout,architectural style as well as the high integration with natural environment which have been accumulated in this old town,are very valuable for study and reference in modern city planning and architectural design.


Squids and their by-products are widely used as pre-spawning feeds in marine fish hatcheries. Therefore, we studied the fatty acid composition of mantle tissue, arms, fins, and gonads of the marine cephalopod, Loligo vulgaris, from a broodstock nutrition point of view. Docosahexaenoic (DHA) and eicosapentaenoic (EPA) acids represented nearly half (>45%) of the total fatty acids, with DHA the most abundant fatty acid in all investigated tissues. The fatty acid profile of the gonads differed significantly from those of the mantle, arms, and fins; EPA was present in a significantly higher proportion (20%), perhaps indicating its important role in reproduction. Results indicate that Loligo vulgaris and its by-products can be an important nutritional component of broodstock feeds, serving as a major source of DHA and EPA.


A method is presented for using the high-level descriptions of objects (i.e. their models) to recognize them in an image. A complex object is viewed as a congregation of a set of component parts with simple shapes. The model of an object, therefore, describes the shapes of its component parts and states the geometrical relationships among those parts. This method also includes a recognition strategy which is a simple high-level description of how that object must be recognized. The shape descriptions of the parts are first used to extract a set of candidates for each part from the image. An object candidate is formed whenever a group of part candidates satisfy the model's geometrical relationships. A model-based prediction and verification scheme is used to verify (or refute) the existence of the object candidates with low certainty. The scheme not only substantially increases the accuracy of recognition, but also makes it possible to detect and recognize partially occluded and camouflaged objects. Another advantage of the approach is that to recognize a new object, one only needs to define its model, and thus no programming is required. The user's task is further simplified by the fact that each newly defined model is sufficient for recognizing a new category of objects.<<ETX>>


It is not my intention to go deeply into the controversy that has waged for so many years as to the origin of melanotic sarcoma, for until the histology of nevi is fully determined, this question will not be settled. From the pathologist's side it is of great interest to determine if the cause be epithelial or endothelial, but to the clinician the chief aim is first, to make a diagnosis and, second, to attempt some form of treatment, which unfortunately, is rarely successful. I am speaking entirely of the melanotic type of sarcoma appearing externally, not


A case of Bean's syndrome is reported in which a wide variety of vascular malformations are illustrated. Among these were multiple arterio‐venous malformations including a so‐called vein of Galen aneurysm. A comparison of this case with those in the literature suggests that the pathology in patients with Bean's syndrome may be more varied than heretofore recognized, and that an overlap between this syndrome and the Osler–Weber–Rendu syndrome may exist.


T March issue of the Scottish Medical Journal represents the beginning of a new venture, It is given over to a selected topic which is handled both in breadth and depth by an invited group of experts. It is planned to devote two issues of the Journal each year to this type of approach, depending, of course, upon consumer reaction. It is hoped that the decision to deal with selected subjects in depth will prove of interest to our readers. It goes almost without saying that the ability to undertake such a policy is a further demonstration of the strength of Scottish medicine.


This paper presents an analysis of the additional harmonic losses in a dual three-phase induction machine, conducted for several modulation techniques. The time and spatial harmonics due to inverter supply are analysed using symmetrical components to investigate the effects of magnetic coupling in multi-phase machines. The harmonic losses are measured and segregation of the two loss components (current heat and core) performed in post-processing. The results are then juxtaposed with the harmonic losses in a three-phase induction machine serving as a reference.


Electron beam welding of a titanium alloy (Ti-6Al-4V) and a kovar alloy (Fe-29Ni-17Co) was performed by using a Cu/Nb multi-interlayer between them. Microstructure and composition of welded joints were analyzed by means of optical microscopy, scanning electron microscopy, energy dispersive spectroscopy, and X-ray diffraction. Mechanical properties of welded joints were evaluated by microhardness and tensile strength tests. Results indicated that in case of 0.22 mm thickness of Nb foil, microstructure of the titanium alloy side was mainly composed of Ti solid solution and some intermetallic compounds such as FeTi and CuTi2, whereas in case of 0.40 mm thickness of Nb foil, the appearance of weld was more uniform and hardness of the weld zone decreased sharply. However, tensile strength of welded joints was increased from 88.1 MPa for the 0.22 mm Nb foil to 150 MPa for the 0.40 mm Nb foil. It was found that thicker Nb foil could inhibit diffusion of Fe atoms towards the titanium alloy side, thus promoting the formation of Ti solid solution and a small amount of CuTi2 and eliminating FeTi. In addition, in both cases, Cu0.5Fe0.5Ti was found in the fusion zone of the titanium alloy side, which had an adverse effect on mechanical properties of welded joints.


According to questionnaire survey,documentary material and mathematical statistics,restrictions on elective courses of Lvliang University public sports will be found out and related measures will be proposed to better conduct these courses.


The non-oriented silicon iron sheets are available in two categories as a result of the production process: fully-process and semi-process sheets. For the semi-process type the manufacturer has to apply a supplementary thermal treatment. There was studied the influence of three thermal treatments on Fe-Si non-oriented (NO) sheets: first treatment at 200 °C for 30 minutes in a vibrating oil bath, the second treatment was done at 550 °C for 15 minutes and the third treatment was done at 700 °C. The measurements were realized for every case on sheets cut in rolling direction and in transversal direction with a single strip tester for samples of 280 × 30 mm 2 . To analyze the results was made a separation of the total energy losses in three components: Wh – hysteresis losses, WF – Foucault losses and Wexc – excess losses.


Several methods (e.g. Move Average, Gene Expression Programming) can be used in safety risk monitoring of Hydraulic Power Generation Industrial Control Network. However, it is difficult for a single forecasting model to predict accurately. Based on the idea of ensemble learning algorithm, this paper gives the positive answer of above problem. This paper proposes an asymmetric error cost function (AEC) to evaluate prediction errors. The effect of the algorithm is confirmed.


This Diabetes is such a common dieses found all over the globe, in which blood glucose or in normal terminology the sugar level in blood is increased. It is the condition of the body in which the insulin which is required for the metabolism of the food is not created or body cannot use the insulin produced properly. Doctors say that diabetes can be controlled if it is detected in its early stages. Data mining is the process in which the data can be used for the prediction based on historic data. The intention here is to analysis how various researchers have used the data mining for better prediction of diabetes so that it could be controlled and possible even cured.


In order to absorb the excellent resource and teaching pattern of international higher education on Computer Science,It is the requirement of the evolution and reform of computer education that Bilingual Teaching is widely applied in Computer education.From 2003,our university had been carrying out the bilingual teaching practice on computer education.Based on the application of Bilingual Teaching in the course Computer Networks,this article analyses and discuss about Bilingual Teaching.


The graphitization is affected by the addition of small amount of the elements(such as Si, Al, Ni, B, Cr and Mn etc.) and the pre-treatment(such as cold rolling). Boron is well known element to accelerate the graphitization of cementite in high carbon steels. Also, cold rolling is known to accelerate the graphitization. But the graphitization nucleation mechanism by cold rolling is few reported. Therefore the effect of cold rolling in Fe-0.5%C-1.0%Si-0.47%Mn-0.005%B steel on the graphitization is investigated quantitatively using hardness test, optical microscope and scanning electron microscope, neutron induced microscopic radiography. The nucleation of graphite in cold-rolled Fe-0.5%C-1.0%Si-0.47%Mn-0.005%B steel is formed at void which is formed at pearlite/pearlite boundary by cold rolling. But the effect of cold rolling on graphitization in boron addition steel is more effective than that of no boron addition steel due to segregation of BN at void in boron addition steel.


OBJECTIVE: To examine the durability of disability improvement after 4-year follow-up in patients who received alemtuzumab in CARE-MS II.
 BACKGROUND: Alemtuzumab showed superior efficacy on disability outcomes versus high-dose subcutaneous interferon beta-1a in patients with relapsing-remitting multiple sclerosis (RRMS) who relapsed on prior therapy in the 2-year phase 3 CARE-MS II study.
 DESIGN/METHODS: In CARE-MS II (NCT00548405), patients who relapsed on prior therapy received alemtuzumab (12 mg/day intravenous) at baseline and month 12. In the extension study (NCT00930553), alemtuzumab-treated patients could receive as-needed retreatment 蠅1 year apart or other disease-modifying therapies. Endpoints included change from core study baseline in Expanded Disability Status Scale (EDSS) score (stability, or 蠅0.5 point increase [worsening], or ≤0.5 point decrease [improvement]) and sustained reduction in preexisting disability (SRD: 蠅1-point EDSS decrease from baseline EDSS score over 蠅3, 6, or 12 months [patients with baseline score 蠅2.0]).
 RESULTS: The extension study enrolled 393 (93[percnt]) alemtuzumab-treated patients from CARE-MS II. During the 2-year extension phase, 68[percnt] received no further treatment courses; 24[percnt] received 1 additional course, and 7[percnt] received 2 additional courses. The proportion of patients with SRD increased further at Year 4 (41[percnt]) vs Year 2 (29[percnt]). Among patients who had EDSS improvement at Year 2, an additional 14[percnt] improved further at Year 4. At Year 4, 66[percnt] of patients had EDSS scores that were stable (27.6[percnt]) or improved (38.6[percnt]) from core study baseline.
 CONCLUSIONS: After 4 years, most patients' EDSS scores were stable or improved relative to pretreatment baseline despite 68[percnt] of the patients having received their last alemtuzumab treatment 3 years previously. The results demonstrate a durable effect of alemtuzumab after 2 annual treatment courses. These findings support the use of alemtuzumab in RRMS patients who received prior disease-modifying therapy.

The recently developed French hYdrometerological Reanalysis (FYRE) covers the period 1871-2012 and provide high-resolution ensemble reconstructions of both climate and hydrology over France. FYRE Climate combines a statistical downscaling of the global Twentieth Century reanalysis (Caillouet et al., 2019) with in-situ station observations through Ensemble Kalman filter (EnKF) data assimilation (Devers et al., 2020). FYRE Climate is composed of 25 members of daily temperature and precipitation fields on a 8~km grid over France. It served as forcings for a conceptual hydrological model over 661 near-natural catchments to build streamflow reconstructions spanning 142 years. These reconstructions have then been combined with historical streamflow observations, again through EnKF data assimilation, to build the FYRE Hydro 25-member daily hydrological reanalysis over the 661 catchments.

FYRE Hydro is here validated with various types of documentary evidence (poem, complaint letter, and photograph), focusing on extreme low-flow events and their spatial and temporal fingerprint. They serve as examples of naturally extreme hydrological events that are exacerbated through human interventions, the magnitude of which has yet to be consistently quantified over the course of the Anthropocene.

Posttraumatic stress disorder (PTSD) has been reported following traumatic brain injury (TBI), even when TBI leads to amnesia for the traumatic event. This study aimed to investigate the relationship between memory for the event (as assessed by the Traumatic Memory Inventory) and reporting of PTSD symptoms in a sample of adults with mild-severe TBI (n=21). Physiological reactivity (heart rate and activity level) was recorded in order to investigate the possible role of sub-conscious processes (such as implicit memory or fear conditioning) in the development of PTSD after TBI. PTSD symptoms were assessed by a self-report questionnaire (Post-traumatic Diagnostic Scale; PDS) and the Clinician Administered PTSD Scale so as to compare previously reported diagnostic rates established with these measures (Sumpter and McMillan, 2005). Higher PTSD severity scores were not, as predicted, associated with recall of the event. Amnesia for the traumatic event may not protect against PTSD development and other factors associated with recall (such as emotional response and confidence in accurateness) may be relevant. Predicted increases in heart rate and activity level during trauma recall were not found and results do not support the role of sub-conscious processing as a causal mechanism for PTSD development after TBI. Rates of diagnosis established using self-report and interview measures support previous evidence that the assessment of PTSD after TBI is confused by overlapping symptoms and that valid diagnosis can only be established with clinician judgement.


This correspondence considers the performance evaluation of precoded orthogonal frequency division multiplexing (P-OFDM) based on Walsh-Hadamard Transform (WHT) in the presence of symbol timing offset (STO). The signal-to-interference plus noise ratio (SINR) is evaluated for flat and frequency-selective fading channels (FSC), where closed-form analytical expressions are derived for the flat fading case. In FSC, the SINR is obtained using Monte Carlo simulation due to the analysis intractability. The bit error rate (BER) performance of OFDM and P-OFDM based on WHT, Haar, and Zadoff-Chu matrix transforms are considered to demonstrate the STO impact on the BER using various precoding transforms. The obtained results show that the impact of STO on P-OFDM is substantially different from conventional OFDM. In particular, it is found that STO affects the SINR of each subcarrier differently, where the SINR of certain subcarriers is severely degraded while others are immune. Furthermore, the diversity gain advantage of the precoding process may vanish for large STOs.


THE role of genetics in improving the health and welfare of production animals will be studied as part of a new partnership between the University of Edinburgh and Genus, a company that develops new technologies in animal breeding to improve the production of pork, beef and dairy animals. Under the partnership, funding will be provided for three years to support existing and future collaborative research projects between Genus, the Roslin Institute and the Royal (Dick) School of Veterinary Studies. It will also support educational initiatives. The University of Edinburgh says that research undertaken within the partnership might include the identification of genes that provide resistance to disease, in order to improve the quality of livestock and help ensure sustainable food production for a growing global and increasingly urban population. David Hume, director of the Roslin Institute, said: 'This new partnership underpins our world-leading position in the field of livestock improvement and is central to our institute strategy of engaging with industry to ensure the maximum impact from our research. It provides a collaborative platform to translate insights from basic research on genetics and genomics directly into the improvement of the health and welfare of production animals.' Dave McLaren, director of research at Genus, added that the signing of the partnership agreement represented a milestone in the relationship between Genus and research institutes. It was, he said, 'clear recognition that, here at Genus, we recognise the benefits of working with a world-leading research organisation such as the Roslin Institute to progress our vision of pioneering animal genetic improvement to help nourish the world.'


In H. Scheiblauer et al. [1], the order and numbering of the sequences in the printed version of Table 2 (Amino acid alignment of the 'a' determinant of the S gene of the eight samples of the ICBS HBsAg Quantitative Panel) and Table 4 (Amino acid alignment of the HBsAg mutant samples of the ICBS HBsAg Clinical Panel which caused reduced sensitivity in some HBsAg test kits figures) are wrong. The replacement of the mono-spaced 'Courier New' font used in the two tables in the original manuscript with the AdvROTIS-S font used in Vox Sanguinis print style has lead to shifting the letters and spaces from their exact location in the sequence map thus changing the location ⁄ placement order of the amino acid alignment in Table 2 and Table 4. Emphasis is given that the original data, the text content of the paper and the conclusions remain correct (the two tables with correct alignment will be placed on ICBS Web site: http://www.icbs-web.org).


In order to found a method based on tissue cultured plants to identify the virulence of Ralstonia solanacearum, a strain of this pathogenic bacteria with different concentrations was inoculated to the tissue cultured tomatoes by leaf-cutting and root-irrigating. The results showed that four days after inoculation, symptoms of the bacteria wilt were found on the cultured tomatoes. When the range of the concentrations was between 8.0×106cfu/ml and 5.2×109cfu/ml, the concentrations had something to do with the latent period of the bacteria wilt. If the concentration was lower, the latent period would be longer. There was no distinctly difference between the concentrations and the ratios of the wilt. Eight days after inoculation, expect for the tomatoes inoculated with the bacteria at the concentration of 8.0×106cfu/ml by root-irrigating, the ratios of the wilt from other treatments were 100%. The inoculating of the bacteria by leaf-cutting, the latent period of the wilt was longer than that of root-irrigating, but the happening speed of the wilt was faster than that of root-irrigating. Furthermore, the present paper made a discussion on the advantage of using the tissue cultured plant to identify the virulence of R. solanacearum.


Facial landmark detection and action unit (AU) recognition are two essential tasks in facial analysis. Previous works rarely consider the relationship between these complementary tasks. In this article, we introduce a novel multi-task dual learning framework to exploit the relationship between facial landmark detection and AU recognition while simultaneously addressing both tasks. When both tasks share middle-level features, common patterns can be exploited and middle- and high-level features can be used to perform facial landmark detection and AU recognition, respectively. In addition, a dual learning mechanism is designed to convert the predicted landmarks and AUs of the label space to the corresponding facial image of the image space, further exploring the strong correlations between the tasks. By jointly training the proposed method at both the feature and label levels, each task improves the other. Experiments on two benchmark databases demonstrate that the proposed method can leverage dependencies to boost the generalization of both tasks.


Duty cycling mode is widely adopted in wireless sensor networks to save energy. Existing duty-cycling protocols cannot well adapt to different data rates and dynamics, resulting in a high energy consumption in real networks. Improving those protocols may require global information or heavy computation and thus may not be practical, leading to many empirical parameters in real protocols. To fill the gap between the application requirement and protocol performance, in this paper, we analyze the energy consumption for duty cycled sensor networks with different data rates. Our analysis shows that existing protocols cannot lead to an efficient energy consumption in various scenarios. Based on the analysis, we design a light-weight adaptive duty-cycling protocol (LAD), which reduces the energy consumption under different data rates and protocol dynamics. LAD can adaptively adjust the protocol parameters according to network conditions such as data rate and achieve an optimal energy efficiency. To make LAD practical in real network, we further pre-calculate optimal parameters offline and store them on sensor nodes, which significantly reduces the computation time. We theoretically validate the performance improvement of the protocol. We implement the protocol in TinyOS and extensively evaluate it on 40 TelosB nodes. The evaluation results show the energy consumption can be reduced by 28.2-40.1 percent compared with state-of-the-art protocols. Results based on data from a 1,200-node operational network further show the effectiveness and scalability of the design.

Abstract Maize lethal necrosis (MLN) disease emerged as a threat to maize, which is an important food security crop in the majority of Sub-Saharan Africa countries. The study was carried out to determine the transmission of Maize chlorotic mottle virus and Sugarcane mosaic virus through seeds harvested from maize varieties; H614 and WE1101 with varying MLN disease severity and evaluate the effect on germination, emergence, disease intensity, virus titre and yields. Field and greenhouse evaluations were conducted over two cropping cycles during the 2016 short rain and 2017 long rain seasons. Maize chlorotic mottle virus was detected in plants from seeds of symptomatic mother plants. Seeds from MLN-infected plants resulted in a significant effect on the plant growth, disease intensity, virus titre and yields. The study underscores the importance of seed testing for viruses causing MLN disease as an integral part of maize seed certification for effective management of the disease.


Objective To observe the stability of recombinant phage-displayed diabetes type 1 vaccine seeds at different temperatures. Methods Store the recombinant phage-displayed diabetes type 1 vaccine seeds containing glycerol as stabilizer at dif- ferent temperatures, using those containing no glycerol as control. Take samples on different days after storage for determination of phage titer by plaque assay. Results The titers of vaccine seeds decreased rapidly at 37 and 25℃, while decreased slowly at 4 and -20℃. Glycerol showed no significantly protective effect on the vaccine seeds stored at 37, 25 and 4℃, while showed significantly protective effect at -20℃. Conclusion Rcombinant phage-displayed diabetes type 1 vaccine seeds may be stored for a short time at 4℃, while for a long time at -20℃, and glycerol may be used as a stabilizer.


Sealed radioactive sources for school science became available during the 1950s from educational equipment suppliers and by the 1960s and early 1970s many UK secondary schools had purchased sets of them. These sources have been in use since then, which raises the question of their safe service life. A study was undertaken to examine the condition of a relatively large sample of school sources to see whether there are signs of source integrity beginning to fail and whether there are any patterns to failures, particularly those that may be age-related. The findings may be helpful to schools when undertaking reviews of the sources they hold and making judgements on keeping older sources in continued use

In an article entitled "Parallel Universes" in the May 2003 issue of Scientific American, Max Tegmark presents a clear and comprehensive picture of the parallel-universe idea. What Tegmark describes is actually a set of related concepts which have in common the notion that there are universes beyond the familiar observable one that astronomers can see parts of directly with telescopes and other instruments. Some of these parallel universes are completely unlike our own; others are nearly identical; still others are identical up to a point and then split off into might-have-been worlds of choices not made. Tegmark's main argument is that, far from being a shadowy, speculative corner of cosmology, the parallel-universe idea has been increasingly confirmed by recent experiments, and we should get used to it because it appears that it will be around for a while.

This paper describes the concept of hierarchical visual cryptography using RKO technique. The key idea behind hierarchical RKO is to encrypt the secret information in number of levels. As the number of levels in hierarchical visual cryptography increases, the secrecy of data tends to increase. The shares generated out of Hierarchical visual cryptography are found to be random giving no information. The RKO technique generates two shares of the original image: one random share and the other key share. These shares are further divided into four more shares using the same RKO technique. From these four shares two final shares are generated. The original secret image can be recovered from the two shares simply by XORing the two shares without any loss of image quality. If any shares other than final shares are XORed it won't reveal the original image.


Social work educators have voiced differing views about the best preparation for practice. Some feel that two types of social workers are needed: one to help people in trouble and one to work toward changing society. Other educators advise that programs be aimed at developing general skills. The authors discovered that by concentrating on producing truly educated individuals this conflict was avoided and graduating interns were prepared for a multitude of careers. This individualized educational approach involved the interns in all educational decisions, which helped develop a mature, creative thinking style.

Abstract : Randomization procedures are shown to offer a viable approach to the analysis of ballistic data in a variety of settings. Distribution assumptions are unnecessary and, of even greater importance, random samples of data are not required. Small sample sizes, while never welcome, can also be accommodated. The price paid for randomization is increased computation, since every problem requires a tailored solution. Application of normal theory may only be valid to the extent that it approximates the results obtained from randomization. Reconciliation of some theoretical questions raised by the application of randomization procedures to ballistics data establishes this is an important and practical area of research.


Objectives. To evaluate efficacy of the early stages detection of the colorectal cancer at using the fecal lactoferrin. Methods. 46 patients with the colorectal cancer, 46 patients had the irritable bowel syndrome and 25 healthy volunteers were included into the investigation Results. It has been established that in the non-invasive diagnostics of the colorectal cancer on the I-II stages of the disease fecal lactoferrin is of a high diagnostic value with the area under curve at 0,36± 0,0349 and doesnt differ from the immunochemical test on the feces occult blood (0,939±0,342, p=0,95). The marker hadnt any statistic differences while comparing this parameter in the patients with malignancies on the I-II and III-IV development stages (p=0,67). Fecal lactoferrin sensitivity in determination of the colorectal cancer on the I-II stage of the disease made up 72,00% (95% CI: 50,6-87,9). Conclusions. Fecal lactoferrin is an effective marker on the early stages of the colorectal cancer.

The exploration capacity of full waveform inversion (FWI) for deep targets is affected by the acquisition geometry, the complexity of overlying strata, and the dip angle of the target. It is of great importance to analyze the relationship between the dip angle of the target reflector and the incident/scattered angle of the wavefields near the target, to achieve the illumination distribution and improve the inversion quality accordingly. We propose an angle domain illumination compensated FWI strategy, which utilizes the local resolution function as preconditioning to the gradient of FWI in the local angle domain, to improve the inversion capability for deep targets. The local resolution function describes the inversion capacity for the local target in the target dip coordinate, which can be generated from the local illumination matrix that contains the illumination information for the target from the different incident and scattering directions. The Marmousi model and the SEG/EAGE salt model are used to show the validity of this method. Results from the numerical experiments prove that the proposed method can effectively improve the inversion performance as well as increase the convergence of FWI.


This article presents a method for detection of H.264 steganographic algorithms that modulate quantized transform coefficients (QTCs) for data hiding. The in-loop deblocking filter specified in the H.264 standard is used for attenuating the discontinuities at coded block boundaries. However, our investigation indicates that the deblocking filtering process would probably be affected by QTC modification. Therefore, we suggest performing steganalysis by considering the influence of QTC modification on filtering decisions and filtering operations. In the filtering of luma block edges, for each luma sample, we try to obtain the cumulative amount of modification applied to it caused by filtering operations, and determine the frequency of the modification made to its sample value. Based on this, a 768-dimensional feature set is designed for training and classification. Extensive experiments were conducted under a range of setups to evaluate the effectiveness of the proposed method. The corresponding experimental results demonstrate that, compared with the prior art, our proposed method is generally capable of providing superior performance on detecting QTC modification in H.264 video, even at low embedding strengths.
