The load distribution on the wallboard is the basis of structure optimization of the wallboard of printing press. A testing method of dynamic strain on the wallboard of printing press is presented. By analyzing the arrangement of printing cylinders and transferring mechanism and other main components, the tested point positions with the strain information of the wallboard are determined. A kind of sensor, which measures strain on perpendicular directions, is developed, a dynamic strain testing system is setup, and then with this, the strain on the wallboard near cylinders is measured under every working condition of press. The function of strain on tested points and rotation of cylinders is established based on the datum mark of the press as zero testing point. Finally, according to the measured results, analyze on the rule between strain on the wallboard and press rotation. It is shown that the distortion of press is increased according to the increasing of the machine speed. And the maximal distortion is on the time of switch of the gaps of cylinders from the state of separation to impression. These conclusions are the foundations of structure optimization for presses.


Kinase-phosphatase signaling plays an important role in cellular signaling pathways. The genome of Mycobacterium tuberculosis, (the causative agent of tuberculosis), is embossed with several kinases and phosphatases. Recently identified protein tyrosine kinase (PtkA) is a novel tyrosine kinase that phosphorylates protein tyrosine phosphatase A (PtpA) and regulates its secretion in the cytosol. PtkA is considered as a regulatory protein. In this study, the mycobacterial proteins regulated due to the ptkA gene deletion in Mtb-H37Ra have been studied and highlighted using two-dimensional (2D) gel electrophoresis coupled with MALDI TOF MS/MS analysis. We have identified 13 differentially expressed proteins that play an important role in mycobacterial intracellular survival and pathogenesis.

Based on literature data and own observations made in 10 out of 11 islands of the Fourni complex (eastern Aegean, Greece), seven reptile taxa are known to occur on this Archipelago. The presence of Hemidactylus turcicus was not known before. Concerning the most abundant forms, densities of individuals observed in the various habitat types are presented. Highest densities were observed in the maquis vegetation. The spectrum of reptile species is comparatively poor and indicates close affinities to the herpetofauna of the eastern Aegean and Dodecanese islands.


Can it be consistent to be interested, for moral reasons, in the fact that uninvolved spectators of a regime change are enthusiastic about that change, when the latter is carried out according to means considered immoral or unjust? Yes. In 'An Old Question Raised Again' (The Conflict of the Faculties, 1798), Kant demonstrates a morally based interest in disinterested spectators' expressions (aesthetic judgments) of enthusiasm for the idea of a republican form of government. This interest is puzzling. Kant's universalizability test supposedly forbids the violent revolutionary means taken to establish the republican constitution. How can the Kantian, if consistent, take an interest in expressions of enthusiasm elicited by these immoral events? In addition to endorsing the familiar means/ends distinction, this article provides a new answer to this question by examining the enthusiasm in which Kant takes an interest: it is a pure aesthetic judgment of enthusiasm, made by a disinterested, impartial spectator.

Introduction: Evidence-Based Practice (EBP) refers to the set of attitudes from which one can know and apply the best
evidence, understand patients' preferences and use clinical experience to optimize care, as well as facilitate decision
making by health teams. to prole physical therapy professionals as to their unde Objectives: rstanding and application of EBP in their clinical
routines. Methods: this is a survey study involving 146 physiotherapists of both genders, from all Brazilian regions. The professionals were
contacted exclusively by e-mail, through their respective regional professional councils, in order to receive the electronic questionnaires,
prepared for this purpose using the Google Forms platform. The questionnaires were available for 90 days, after which they were no longer
accepted. Results: 74.6% of the sample was female; there was almost unanimous agreement that EBP is necessary in clinical practice.
Approximately 95% agreed that EBP can be applied even in high demand settings and 84.4% said they were able to insert the guidelines of
practice guides into their clinical routines. However, it is noteworthy that 98.6% said they lacked the ability to search relevant scientic literature
and the main reasons for not performing EBP were: lack of time, lack of ability to search relevant scientic literature and lack of ndings on a
given patient population. the authors conclude that Brazilian physical therapists recognize the im Conclusion: portance of EBP as a guide for
clinical decision making and that they use it in their professional routines, however, they need adequate orientation on efcient scientic searches
in order to promote treatment excellence through reliable scientic materials.

One of the opportunities the corpus linguistics has given us is to explore words and phrases within their contexts. Thanks to large corpora, linguists have, for the first time, a chance to look at the language from the syntagmatic point of view as opposed to the traditional paradigmatic focus of linguistics. Contextual research may be used in different ways. Context has always played a crucial role in translation and translation-oriented research or contrastive linguistic studies, but it can also shed light on grammatical, lexical and semantic properties of certain word groups or parts of speech.


Huntington disease (HD) is a brain disorder evoked by expanded CAG repeats in HTT gene which results in long polyglutamine tract in huntingtin protein (HTT). Interestingly, the subtle patient symptoms which are observed decades before overt HD symptoms and the molecular changes observed in cell and models demonstrate that the disease process begins earlier. The questions that remain are how early the molecular changes related to HD occur, and whether HD may be accounted as neurodevelopmental disorder. Therefore, it is essential to investigate the molecular signs of HD in cellular models reflecting the sequence of neurogenesis including pluripotent (e.g. iPS) and neural stem cells. Therefore, we investigated naïve mouse HD YAC128 iPSCs and human HD iPSCs from HD and juvenile HD patients, to detect whether HD-related phenotypes can be already observed in pluripotent cells. Indeed, we found multiple alterations including the deregulation of the MAPK and Wnt signaling pathways and genes related to oxidative stress, such as SOD1. Interestingly, a common protein interactor of the huntingtin and the proteins in the above pathways is p53, and the expression of the p53 gene was deregulated in HD YAC128 iPSCs and human HD iPSCs. We further expanded the analysis to the iPS-derived neural stem cells (NSC) and found that p53 is also downregulated in HD NSC lines. To investigate whether the expression of mutant huntingtin interferes with Wnt, Erk and p53 pathways we established isogenic HD-YAC128-iPSC and derived NSC lines with stable knockdown of mutant huntingtin expression by shRNA. We found that the level of mutant HTT expression modulated by shRNA is reversely correlated with the level of p53 resulting in normalization of its expression upon mutant HTT silencing. Investigation of shRNA expression lines delivered no clear evidence for changes in Wnt and Erk pathways upon huntingtin silencing in NSC and iPSC. Our findings demonstrate that molecular HD signatures are already altered in undifferentiated pluripotent cells and that the pathogenesis of HD may start early in life. We also found that the deregulation continues along the CNS developmental cellular stages to the stage of Neuronal Stem Cells, illuminating HD as a putative neurodevelopmental disorder. An important molecule participating in early HD stages is p53, and its level in pluripotent and NS cells is dependent on the level of huntingtin therefore can be a valid molecular target for early therapy.

A serious degradation of detection probability (Pd) in a cellaverging constant false alarm rate (CA-CFAR) detector is known to be caused by the presence of an interfering target in the set of reference cells. A technique which is often used to prevent excessive false alarms at clutter ¿edges¿ is a ¿greatest of¿ (GO) selection between the leading and lagging sets of cells (GO-CFAR). However, it is demonstrated for a Rayleigh target that the abovementioned suppression effect is more acute in the GO-CFAR. Practically, detection of closely separated targets is almost inhibited. Selection of the ¿smallest of¿ (SO) the means for the adaptive threshold has been proposed to alleviate this problem. An analytic expression for Pd of this detector is also derived, and it is shown that though it does prevent the suppression effect, a large sensitivity loss is introduced unless the number of reference cells is sufficiently large. A modified CO-CFAR detector, combining a ¿censoring¿ circuit, is proposed for automatic detection in a complex nonhomogeneous environment.

Our previous findings demonstrating that endogenous HCV homolog fragments present in the European rabbit (O. cuniculus) and European hare (L. europaeus) genomes can replicate in Madin-Darby bovine kidney (MDBK) epithelial cell, as well as that Hepatitis C-like viruses are produced in the same cell line upon its inoculation with European rabbit and European hare DNA, led us to investigate if synthetic fragments with total homology between core, E2 and NS4B HCV proteins and the European rabbit genome have the ability to internalize and replicate in naïve MDBK cell line. The efficient internalization and replication of the selected tested samples could be demonstrated by virus titers detection using the quantitative realtime RT-PCR analysis. Text Unmodified or modified HCV genomic RNA belonging to different HCV genotypes have been synthesized, cloned and then transfected into different cell lines, such as hepatoma cell line (Hep) or Hep3B cells, resulting in the production of infectious viral particles or pseudoparticles (1, 2, 3). It was reported that unmodified genomic RNA derived from the HCV-2a JFH-1 strain produced infectious virions after transfection into Huh-7 hepatoma cells (1) and that modified synthetic RNA derived from a prototype HCV-1a H77 strain containing five adaptive mutations also shows an efficient replication in Huh-7 cells after transfection (2, 3). Moreover, a study on computational reconstruction of a representative synthetic HCV-1a (bole1a) pseudoparticle that robustly infect Hep3B cells was described (4), as it was also


This research proposal aims to study an emerging technology that is beginning to appear in the workplace. Intelligent employee assistants (IEA) are IT artifacts that help employees via natural language to relieve employees from routine tasks, collaborates with employees, makes recommendations and performs actions. These applications are being implemented and deployed by organizations to support employees. Examples of such applications include Alexa for Business and Nokia's Multi-purpose Intuitive Knowledge Assistant (MIKA). IEAs have the potential to disrupt the workplace as they will perform ever-increasing tasks to enhance employee performance. However, human language is ambiguous; communication is a complex process and employees may have worries about losing control over their jobs being taken over by intelligent artificial applications such as IEAs. This research proposes to investigate the interaction between employees and IEAs and study the elements that break down communication and impede performance using the transactional communication theory.

Dynapod is a portable pedal operated power device that consists of a stand, saddle, handlebar, chain and sprockets, cranks and pedals. A person can generate four times more power by pedaling than by hand cranking. However, continuous pedaling at this rate could be done for only short periods (about 10 min). Pedaling at about half this power (90 W) could be sustained for around 60 min. Most people engaged in delivering power continuously for an hour or more would be most efficient when pedaling in the range of 50 to 70 rpm. In respect to the objective of the study, the design parameters for dynapod and the development of dynapod, a postural dynamometer for foot operated rotary power generation was designed and developed. Experiment was conducted for optimization of flywheel, pedaling rate, power output, saddle height and crank. Heart rate, oxygen consumption rate (OCR), blood pressure (BP), pulse oxygen saturation extent, rate of perceived exertion (RPE) were taken as dependent variables. The flywheel of diameter 550 mm was found to be suitable for dynapod. The optimum pedaling rate increased from minimum of about 45 rpm at 30 W to a maximum of 52 rpm at 90 W. The rate of perceived exertion (RPE) increased with increase in pedalling rate at given power output. Crank length of 180 mm and saddle height of 0.96 trochanteric height gave the minimum physiological responses. The dynapod can be successfully used as an interface between the human worker and a hand operated stationary farm equipment in pedalling mode for getting more output from the machine with less effort and fatigue.

Earthquakes are described as the most destructive and unpredictable disasters around the world. Many types of consequences are presented as possible negative effects including health-related of them. Identifying and categorizing the various health risk factors is an initial goal in an uncomplicated earthquake setting. Effective organization of the health care system (HCS) in case of complicated medical situation due to earthquakes and tsunamis is a serious challenge. The healthcare system operates at high speed with considerable difficulties in the event of a large magnitude outbreak of a traumatic defeat an earthquake. Possibilities to take adequate solutions in conditions of the worst-case earthquake scenario with the subsequent provoked multi-secondary disasters as tsunamis and with multi-secondary risk factors are highly motivating for the medical community with critically low resource constraints. On the one hand the analysis of the structure of mass victim and medical triage in a complicated scene due to earthquakes is a difficult process. On the other hand medical provision of the population in highly destructive earthquakes is limited by time.


Research on antifungal activity of ethanolic extract of nimba leaves (Azadirachta indica) against Candida alb icans were done using dilution method. Extracts were produced from two different extraction method i.e. soxhlet and maceration using ethanol 70% as solvent. Determination of compounds contained in extracts used Thin Layer Chromatography. The research resul ted that soxhlet and maceration extract of nimba leaves showed antifungal activity against Candida albicans. Soxhlet extracts exhibited higher activity than maceration extract to inhibit Candida albicans. Thin Layer Chromatography revealed that maceration and soxhlet extracts contained flavonoid, tannin and saponin.


If non-chiral smectic C host phases are doped with chiral guest molecules, helically structured SC* phases are formed by symmetry breaking. If the chiral dopants bear transverse dipoles a spontaneous polarization, PS, will occur in these so-called induced SC* phases. In 'classical' dopants the chiral centre(s) as well as the transverse dipole(s) are situated in alkyl side groups (type I dopants). The tilt-angle, reduced polarization, PO=PS/sin θ(θ= tilt angle), in these mixtures are independent of the host with a linear dependence on the guest mole fraction, xG. As a material parameter the polarization power, δP=(∂PO/∂xG)ΔT, has been introduced and is discussed in terms of the molecular structure of the dopant. Deviations of PO(xG) from linearity can be considered by a local field correction. Novel chiral dopants bearing the chiral centre(s) and the transverse dipole(s) in a rigid core (type II dopants) exhibit a significant dependence of the magnitude, and sometimes even of the sign, of PO on the nature of the host. The different behaviours of the two dopant types are discussed by means of a microscopic model and can be understood in terms of a hard core guest-host interaction which influences the rotational distribution of the dopant molecules with respect to their long molecular axes.


Arising in the wake of the major historical disasters of the XXth century, the works of William Faulkner, Joseph Roth, Claude Simon, Georges Perec and W. G. Sebald question the paradoxical inheritance of a vanishing tradition. When the ghosts of history return to haunt the present, this is because their own universe has disappeared, and with it the traditional ways of transmission which ensured the survival of the ancestral world, as well as its representation. Rather than demonstrating the living presence of the past, this haunting presence thus seems to escort the certainty of an unredeemable death, a loss which no literary or artistic monument could make up for. Whereas Romantic representations of the dead associated writing with a form of grave-digging, capable both of resurrecting the dead and making up for their loss, the memory of the departed, in these narratives, is and remains fundamentally melancholic, insofar as it constantly marks the limits of literary resurrection and the fragility of narrative attempts in themselves threatened by the destructive power of Time. However, this departure from the model of the scriptural grave by no means stifles the call for justice accompanying such spectral apparitions. By answering the call of that which is irretrievably lost, these works bear the imprint of a process of memory and oblivion which attempts to recall the memory of the departed, but most of all to keep a trace of their loss. The double ethical pursuit of works such as these, built on the full recognition of the reality of unredeemable death, is to record what can possibly be recorded, and to mark the empty place of that which is beyond recall.


The invention provides a method for lowering the coefficient of friction of the surface of metal bands with a coating, especially of tin-plated or chromium-plated steel bands (S), which are passed through a coating installation at a band speed (v). To be able to lower the coefficient of friction of the surface of the coating even at high band speeds through the coating installation, according to the invention, an aqueous solution of a tenside is sprayed onto the coated metal band passed at the band speed (v) after the coating process. The invention further provides a device for applying a metallic coating onto a steel band, especially in a band tin-plating installation or band chromium-plating installation.


In this paper, planar SiC 900 V 60 mΩ MOSFET was investigated with gate oxide reliability by gate oxide integrity and intrinsic TDDB measurement. The gate oxide showed reliable VBD of 46 V capacity and good TDDB lifetime performance. The intrinsic TDDB lifetime follows the linear E-model allows a confidential prediction of the failure rate within the lifetime less than 0.1 ppm in 20 years for +18 V and 175 °C temperature use conditions with wafers and TO-247 packages. Avalanche ruggedness was also confirmed by measurement the ruptured distribution by unclamped inductive switching (UIS) and investigated the failure location. Avalanche stability of BVDSS was confirmed and was showing reliable and robust over 900 V BVDSS.


Technological advancements and modernization of different industries and disciplines contributed to more consumption of oil and electricity which powers these industries. Aligned with the United Nations (UN) Sustainable Development Goals (SDG), the use of alternative and renewable energy (RE) sources is encouraged as it allows the utilization of clean energy resources and access of populations in developing countries to electricity and energy. Forecasting and maximizing the harvest for renewable energy requires an understanding of the mechanics behind the variables that impact solar photovoltaic production. 755 datasets were created from 150 days of recorded data and used in the model building and sensitivity analysis. The approach used in this study to identify the variable importance of each meteorological variable to the solar photovoltaic (PV) production was the Garson's algorithm (GA). In this study, an artificial neural network (ANN)-based sensitivity analysis (SA) using Garson's algorithm (GA) was implemented to identify the relative importance (RI) of the factors influencing the solar PV output including the solar irradiance (SI), rainfall, maximum temperature (MaT), minimum temperature (MiT), relative humidity (RH), and wind speed (WS). The model also considers the relative significance of these parameters to the solar PV output. Results indicate that, with a relative value of 29.48% and 5.01%, respectively, solar irradiance and wind speed are the most and least important factors.


A new algorithm is presented for electronically steering a crossed-loop VLF receiver antenna array to remove interference. The algorithm is a modification of the eigenvector sorting algorithm, which exploits spatial correlation statistics. The new algorithm is intended for situations where the wanted signal is from a transmitter at close range and therefore has horizontal circular polarisation, but the interferer is from a long range and so has linear polarisation. Exploiting the difference in polarisation by discarding the imaginary part of the correlation matrix, allows accurate null steering even when the interferer is of equal power to the wanted signal. The algorithm can also separate the differently polarised signals when they come from the same direction.


Abstract —The modern world continues to change as Information Technology (IT) related applications proceed to evolve at a rapid pace. The need for IT continues to grow as we begin to meaningfully engage its products in both business and the academic settings. The increased need for information security, networking and database expertise after 9/11 followed by the rebound of the US economy, has resulted in the upswing of IT employment since the first quarter of 2005. Starting 2005, highly skilled IT workers are commanding ever-higher wages as the IT employment scene shifts to a more narrowly focused marketplace. According to the Yoh Index of Technology Wages reported on February 6 2006, the IT wages increased by 3.1 percent overall in the 4th quarter of 2005 over the like quarter in the previous year. However, all of the above positive social and economic reports are not yet reflected in the ongoing decrease in enrollment of IT graduate and undergraduate college students. In this paper, we present our work on developing universal accessible content for the IT minor courses. We also discuss the effective teaching and learning methods for this generation along with planning for such challenges from an institutions perspective.


The article is devoted to the implementation of the principles of competitiveness and equality of parties in civil proceedings when appointing forensic examinations. The author notes that the current legal regulation does not properly ensure their observance, considers the problem through specific examples from judicial practice. It is concluded that the courts should carry out a number of preparatory measures before the appointment of forensic examinations, motivate the expediency of appointing a repeated or additional examination, as well as rejecting the arguments of the parties. The best form of expressing the position of the court should be considered a reasoned ruling that can be appealed.


We observe that the partition function of the six-vertex model on a finite square lattice with domain wall boundary conditions is (a restriction of) a KP τ function and express it as an expectation value of charged free fermions (up to an overall normalization).


Nowadays, the European fresh tomato market is saturated as a consequence of the growth of supplies from different countries, and Almeria exports contribute to create oversupply in some weeks during the winter. In this paper a model is proposed in order to analyse the evolution of weekly Almeria tomato exports throughout the last two decades. Such an analysis is carried out inside the frame delimited by the structural approach to time series and the usefulness of spline functions as a parsimonious way of modelling seasonal variations in which the period does not remain the same over time is shown.


Abstract We present a new general complex integral transform in this study. This complex transform properties are studied. The main problem is reduced to a simple algebraic equation using this complex integral transformation. By solving this algebraic equation and using the inverse of the general complex integral transform, the answer to this main problem can be found. Finally, the solution to linear higher order ordinary differential equation is found by using the new general complex integral transform. We also present and discuss a number of key real-life problems, such as pharmacokinetics and nuclear physics.


The most noticeable characteristic of executable business rules is that their execution results necessarily in executing some actions: specifically, the actions that are required to enforce the underlying business policy (or non-executable business rule). From an inference point of view, the true assertion that is inferred from a business rule is thus always that some specific actions must be executed. In other words, business rules specify which actions can or have to be executed when certain conditions are met.


Currently, 30 % of total electricity is being generated by nuclear power plants in Japan. Nuclear energy is also an important power generating source which mitigates the global warming by reducing the release of carbon dioxide. On the other hand, nuclear power plants(light water reactor: LWR) started operation in 1970's and the number of so called "aged reactor" which is older than 30 years becomes 20 in the year of 2010. Hence, the safety and economical operation of LWRs is very important in Japan and also in the world. Under these circumstances, Central Research Institute of Electric Power Industry(CRIEPI) has established Plant Life Management(PLM) Project in May 2007 to promote the research to support the safety operation of the aged LWR. This project aims to overcome various material degradation problems under the efficient structure based on the long experience of researches for LWR material in CRIEPI. The PLM project makes researches on neutron irradiation embrittlement of reactor pressure vessel, stress corrosion cracking(SCC) of stainless steels and nickel based alloys, and pipe wall thinning which are considered to be the most important degradation phenomena in LWR component materials. The main targets are to clarify the degradation mechanism and to develop the material data base, and thirdly to establish the prediction and evaluation methods. The final goal is to support the safe and rational operation of the aged reactors in utilities through the reflection of the research results to the codes and standards of academic societies.


We investigated the mechanism of conjugal transfer of the endemic Klebsiella pneumoniae carbapenem resistance plasmid, pKpQIL. Transfer efficiency of this plasmid was found to be dependent on the expression of the major outer membrane porin, OmpK36, in recipient cells. We also found that conjugal uptake is reduced in recipients expressing an OmpK36 isoform associated with the globally pervasive K. pneumoniae ST258 clade (OmpK36ST258). This reduction was attributed to a glycine-aspartate insertion in loop 3 of OmpK36ST258, which constricts the pore by 26%. Deletion of finO, which encodes an RNA-binding protein, derepressed transfer of pKpQIL and enabled visualisation of the conjugation pilus and OmpK36-dependent conjugation in real time. While deletion of traN abolished pKpQIL conjugation, substituting traN in pKpQIL with its homologue from R100-1 circumvented OmpK36 dependency. These results suggest that OmpK36 in recipient K. pneumoniae and the pKpQIL-encoded TraN in donor bacteria cooperate to facilitate plasmid transfer. This is the first report since 1998 to suggest a novel recipient cell receptor for IncF plasmid transfer and supports the idea that TraN mediates receptor specificity for plasmids belonging to this incompatibility group.


To decelerate climate change and limit global warming, there is a need for reducing the environmental impact of vehicles, which can be achieved by increasing their energy efficiency. For a passenger vehicle, one of the largest resistive forces is aerodynamic drag. A significant contribution to the total drag originates from the wheels, making the understanding of their flows essential for creating efficient vehicles. However, wheel flows are complex and challenging to comprehend due to factors such as the rotation, high level of geometrical details and tyre deformation, all of which have been shown to affect drag. For a better understanding, numerical simulations can be used. However, to determine the accuracy of the simulations, these must be correlated to experiments. In this work, both the correlation between experiments and simulations as well as the flow field effect of varying the tyre tread pattern are investigated. Wind tunnel tests using a full-scale DrivAer model have been performed for four tyre tread patterns and two rim designs. First, the numerical simulations are compared to the experiments, where the interference of the wind tunnel on wheel flows is investigated. By performing simulations using both an open road domain and a domain containing a detailed model of the wind tunnel, it was found that the inclusion of the wind tunnel improves predictions of both absolute drag values as well as the drag deltas between configurations. Then, the effects of the different tyre tread patterns are analysed in more detail. Results showed that adding rain grooves typically reduces drag compared to a slick tyre, whereas the effect of lateral grooves is dependent on the rim configuration. In addition to the drag, lift variations were considered. There, the largest effects were obtained at the front axle and, in general, the lift is reduced by the rain grooves and increased by the lateral grooves, most clearly for the closed rim. Also, the influence of the parasitic lift forces acting on the wheel drive units was demonstrated.


Using the example about "Coke merging Huiyaun",how mergers and acquisitions between foreign brands and local brands influence the evaluation of the target brand(i.e.,the local brand) is examined.The results show that emphasizing the mergers and acquisitions will decrease the brand attitude and shopping intention.Moreover,individuals' independence moderates the negative effect of the mergers.Only high independent individuals are affected by the mergers.This study extends the findings about how self-construals influence consumer behaviors and shows that when business behaviors are associated with the self,those behaviors consistent with people's self-construals are more welcome.


We have amorphised Si0.5C0.5 by ab initio generating random networks with the experimental density of 2.75 g/cm3. Two types of crystalline supercells were used at the start: one was a diamond-like periodic supercell of 64 atoms, containing 32 carbons and 32 silicons, chemically ordered, amorphised using Fast Structure®, and the other was an fcc crystalline periodic supercell with 108 atoms, 54 carbons and 54 silicons, chemically ordered, amorphised using DMol3 from the suite in Materials Studio 3.2®. The amorphisation is made by heating the periodic samples to just below the melting point (the undermelt–quench approach), and then cooling them down to 0 K. Then the structures are relaxed by annealing and quenching, and finally a geometry relaxation is carried out. Our simulations show that Cerius2 ® and Materials Studio 3.2 give equivalent results in general: atoms of one kind are almost completely surrounded by the atoms of the other kind. We also find that the two codes lead to total and partial radial distribution functions such that after weighting them with the corresponding experimental structure factors yield curves that are similar and comparable with experiment. Also C–C bonds with an average bond length of 1.35 Å are found.


The relationships between the phenotypic modulation and proliferation of vascular smooth muscle cells(VSMC) were studied by transcription factor"decoy"strategy in which the activation of VSMC\|specific expression genes and proliferation\|associated genes was blocked.The results of gel mobility shift assay showed that the nuclear extracts from differentiated VSMC could bind to CArG double\|stranded oligodeoxynucleotide(ODN),which is a consensus cis \|element for differentiated VSMC\|specific expression genes,and that those from dedifferentiated VSMC could interact with E2F ODN,which is a consensus cis sequence for the genes involved in cell cycle regulation.Transfection of redifferentiating VSMC with GArG ODN could inhibit the expression of smooth muscle α\|actin gene,decrease myofilament content,and prevent redifferentiating of VSMC.Transfection of dedifferentiated VSMC by E2F ODN might result in down\|regulation of \%c\|myc\% gene expression,inhibition of VSMC proliferation,and attenuation of phenotypic characteristics of dedifferentiated VSMC.These results suggest that E2F and CArG cis\|elements might play an important role in VSMC proliferation and differentiation.


A simple method of analysing the limit-cycling behaviour of a sigma-delta modulator is introduced which is used to determine the performance of a system designed specifically for student use. The analysis is extended to predict the closed-loop performance of the modulator.


Image tactile interaction is a new interaction between human and digital images, allowing users to know digital images by touch. In order to improve the authenticity of image tactile perception, this paper proposes a tactile perception model based on image region features. Aiming at the phenomenon of over-partitioning and computational complexity of JSEG algorithm, we propose an improved JSEG algorithm, which can effectively reduce the computational complexity and divide the image areas which are more in line with the subjective visual judgment, and can be used for region-based image tactile generation. The experimental results show that the proposed algorithm can correctly distinguish the image area and improve the accuracy of image tactile perception.


Diphenylmethane diisocyanate (MDI) is widely used in its polymeric form in the manufacturing of polyurethane products. Previous reports on MDI‐related contact allergy have shown a pattern, where patients seem to react to their own MDI‐based work material but not to commercial patch‐test preparations, which contain 4,4′‐MDI. Therefore, we performed chemical analyses of 14 commercial test preparations of 4,4′‐MDI obtained from 8 European and 4 American dermatology departments as well as 2 preparations from 2 major European suppliers of patch‐test allergens. A new method for monitoring 4,4′‐MDI in petrolatum preparations was developed and the determination of 4,4′‐MDI as the MDI‐dibutylamine derivative using liquid chromatography‐mass spectrometry was performed. None of the preparations obtained from the dermatology departments contained more than 12% of the concentration stated on the label. In most cases, 4,4′‐MDI content was only a few percentages or less of the concentration stated. 7 of the 14 preparations were analysed before the expiry date. Yet, only 1 of them, a preparation directly obtained from the supplier, came close to the concentration stated on the label. Thus, using these preparations, patients will be tested with a lower concentration than intended, leading to possible false‐negative reactions.

Abstract Design Theory is a mathematical theory of design based on Yoshikawa's General Design Theory and Barwise and Seligman's Channel Theory. Classifications is the structures of Channel theory, and they are used in Abstract Design Theory in order to formulate a scheme of design. Yoshikawa discussed design in terms of topology in General Design Theory. The aim of this paper is to show properties of topological spaces defined by classifications. For a classification A, we shall define a topological space top(A) and a uniform space unif(A) from A. A topological space with the form top(A) is called a classification space, and we shall show that any classification space is uniformizable. Then, we shall discuss about filters on top(A) and show a mathematical interpretation of Yoshikawa's assertion that the design specification is a filter. Furthermore, we shall argue that the compactness of A, the compactness of top(A), and the completeness of unif(A) are equivalent.Design Theory is a mathematical theory of design based on Yoshikawa's General Design Theory and Barwise and Seligman's Channel Theory.

Scotland and Catalonia share a somewhat similar configuration as substate peripheral nations with analogous perceptions, interpretations and aspirations for home rule within their respective British and Spanish frameworks. Nevertheless, Scotland and Catalonia have not followed parallel processes over the last decades, as far as the achievement of institutional forms of self-government is concerned(!).


Behçet's disease is a systemic inflammatory vascular disorder that may affect the cardiovascular system. Left anterior descending (LAD) artery aneurysm is a rare but potentially fatal complication of Behçet's disease. An accurate diagnosis of this clinical entity requires multimodal imaging (computerized tomography, angiography, and echocardiography) and is essential to guide appropriate therapeutic management. We report the case of a 22‐year‐old female with LAD pseudoaneurysm who underwent surgical repair with transesophageal echocardiography guidance. We describe the importance of the use of an alternative view to define the origin and location of this unusual pathology. (Echocardiography 2012;29:E91‐E93)


Several studies revealed that a small number of glycosylphosphatidylinositol anchored protein-deficient cells are detectable in peripheral blood of healthy individuals but these PNH-type cells do not persist for a long time because they are originated from committed progenitor cells rather than primitive stem cells with PIG-A gene mutations. We have studied more than 700 patients with AA for the presence of CD55-CD59- granulocytes and red blood cells using highly sensitive flow cytometry and detected 0.003% or more PNH-type cells in about 50% of patients. In patients whose proportions of PNH-type are very low, the appearance of PNH-type cells may also be transient because they are not derived from true PIG-A mutant stem cell clones. In an attempt to characterize hematopoietic clones from which small populations of PNH-type cells are originated, we studied changes in the proportion of PNH-type granulocytes, clinical findings, and PIG-A mutations over 3–7 years on 52 AA patients (18 males and 33 females). The initial examination revealed less than 0.1% (0–0.075%) PNH-type granulocytes in 21 patients (Group A) and more than 0.1% (0.101–36%) PNH-type granulocytes in 31 patients (Group B). In three (14%) patients of Group A, PNH-type granulocytes became undetectable 2.9, 1.3 and 1.6 years after the initial examination. 0.007 % granulocytes became detectable 2.5 years after the first examination which produced a negative result in one patient. Among the other 17 (81%) patients of Group A, proportions of PNH-type granulocytes remained stable at 0.03–0.41% over 3–6 years. By contrast, 5 (16%) patients of Group B showed an apparent increase in the proportion of PNH-type cells (from 1.46%, 1.63%, 3.31%, 23%, and 36% to 79%, 21%, 83%, 55%, and 78%, respectively) 2 to 4 years after the initial examination. Four of the five developed clinical signs of hemolysis. The proportion of PNH-type cells in Group B patients remained stable in 33 (63%) patients and declined in 12 (23%) patients. When we sorted a small (0.04%) population of PNH-type granulocytes from a patients of Group A and analyzed PIG-A gene, only one point mutation at position 479, C to T was revealed in the exon 2. The finding that the proportion of PNH-type cells remained stable over 3 years in most Group A patients suggests that very low proportions of PNH-type cells are derived from primitive hematopoietic stem cell clones with PIG-A mutation. Among AA patients displaying small populations of PNH-type cells, only those whose proportion of PNH-type cells are more than 1% may be at a high risk of developing hemolytic PNH.


Shape memory elements generate significant recovery stresses when the shape recovery associated with the reverse martensitic transformation is impeded during heating. This process of stress generation is influenced by many parameters. A fundamental model has been developed to describe this generation of recovery stresses. The model is based on a generalised thermodynamic analysis of shape memory behaviour. The mathematical approach and the assumptions in this model are selected in such a way that the calculations yield close approximations of the real behaviour and that the final mathematical equations are relatively simple. The paper presents also experimental measurements of recovery stress generation for complex restraining conditions. Comparison of the experimental results with the calculated results confirm that this model can be used to predict quantitatively the generation of recovery stresses.


We performed a spectral analysis of the EUVE spectrum and ROSAT data of the unique object H1504+65, which is an extremely hot post-AGB star entering the white dwarf cooling sequence. It is the only pre-white dwarf known, whose surface is free of hydrogen and helium, hence, it represents the bare core of a former AGB star. The EUV spectrum (75--150A) is dominated by strong OVI lines and we can identify a number of NeVII lines.
EUVE and ROSAT data can be fitted with models between Teff=170000 K and 200000 K. We derive an extraordinarily high neon abundance (2%--5% by mass, i.e. 20--50 times solar) which we confirm by an optical NeVII line detected in a Keck HIRES echelle spectrum. This abundance is expected for 3-alpha processed matter and corroborates our understanding of H1504+65 as a C-O stellar core which has lost its entire H- and He-rich envelopes.


This article reviews the benefits of modified, high performance asphalts, notably improved rutting resistance, with less thermal (cold temperature) cracking and overall improved mixture durability. The author notes that many agencies estimate that they can get an additional four to six years of pavement life from a pavement constructed using a modified asphalt binder. The article briefly reviews the history of strategies to lengthen pavement service life, then discusses the different types of modifiers used, including elastomers (rubbers or elastics), and plastomers (plastics), which are two types of the more-generic term, polymers. One common elastomer is crumb rubber, which is made from ground tires. The author also reports on a study undertaken by the Asphalt Institute to quantify the performance benefits of polymer-modified asphalt pavements and overlaps using field data from across the U.S. and Canada. The article concludes with a detailed table that provides information about site features, conditions, and the expected increase in service life when using flexible pavements and hot mix asphalt overlays; site features include foundation soils, water table depth, traffic volume, climate, and existing pavement condition.


Benzothieno[3,2-b]quinoline 1 and benzothieno[2,3-c]quinoline 2 (Figure 1) are known for their anti-plasmodic and anti-infectious activities, acting mainly through intercalation between DNA base pairs when used in their salt form [1]. Normally synthesized by two separated reactions, our group was able to obtain the two compounds in a single reaction. In this work, we present fluorescence studies of the interaction of compounds 1 and 2 with salmon sperm double-stranded DNA using spectroscopic techniques (Figure 1). These studies allowed to determine, through the McGhee and von Hippel modification of Scatchard plot, the binding constants, Ki = (2.6±0.3)×10 M for 1 and Ki = (2.9±0.3)×10 M for 2, and binding site sizes in base pairs (n = 21±6 for 1 and n = 7±2 for 2). Fluorescence quenching measurements using iodide ion showed that both compounds exhibit intercalation in DNA, compound 2 being the more intercalative one. Through the modified Stern-Volmer plots [2], the fraction of intercalated molecules was obtained: 31% for compound 1 and 42% for compound 2. Due to their potential biological activity, these benzothienoquinolines were encapsulated in liposomes of dipalmitoyl phosphatidylcholine (DPPC), dimyristoyl phosphatidylethanolamine (DMPE), egg yolk phosphatidylcholine (Egg-PC) and dioctadecyldimethylammonium bromide (DODAB). Fluorescence anisotropy measurements indicate that both compounds are mainly located in a hydrated and fluid environment, especially compound 1. These studies may be important to future drug delivery applications of these potential biologically active compounds using liposomes, in order to reduce toxic effects or to increase the drug circulation time.

Primary piglet sertoli cell(SC) were used to study the effects of FSH on regulating Glial cell line-derived neurotrophic factor(GDNF) expression.The results showed that:(1) The FSH-stimulated GDNF expression in the cultured SC was time-and concentration-dependent: the level of GDNF protein reached its highest when FSH(50 ng/mL) stimulated 1h.(2) FSH(50 ng/mL)or dbcAMP(100 μmol/L)could active ERK1/2 prominently along with a maximum stimulation at 2 h;(3) U0126(MEK1/2 inhibitor) could apparently inhibited the activing effect of FSH on GDNF.These results suggested that,by activing the cAMP-PKA-ERK1/2 and promting the transcription of GDNF gene,FSH stimulated the expression of GDNF of sertoli cells.

In recent years, the Supreme Court has become increasingly reluctant to imply private rights of action under federal statutes not explicitly providing such a remedy.' The pressure on courts from injured persons seeking a cause of action remains,' however, and as the federal forum becomes less hospitable to private parties, plaintiffs may look increasingly to state courts for vindication of their rights. State court remedies are not necessarily foreclosed by the denial of an implied federal right of action. The demise of implied federal rights of action reflects an acknowledgment of the federal courts' limited power to create judicial remedies for statutory wrongs. The remedial powers of the states, however, are much broader than those of the federal courts; thus even when implied federal rights of action have been denied, states may often be able to provide a right of action to private plaintiffs by creating a parallel state law that incorporates federal law by reference.3 Given the current hostility of the Supreme Court to the implication of federal rights of action, state incorporation of federal standards in a state law right of action presents itself as an appropriate step forward in the vindication of individuals' statutory rights, a step in keeping with the best traditions of a federal system.


In the Developing countries like India the crop failure due to reasons of excess of rainfall and lack of rain fall is a common phenomenon. To compensate with the crop failure the Crop insurance is an immediate resort available to the farming community across the country. The WIBI-Weather Index Based Insurance scheme in Karnataka is the instrument available to farmers and more particularly for the cotton growing farmers. However the common notion is that farmers are not satisfied by crop insurance facility. The present study attempts to understand the performance of WIBI and examines the satisfactory levels of the cotton growing farming in this regard. The detailed analysis of both positive and negative perception of farmers towards weather based insurance is given. The paper highlights that the WIBI performance is marginally satisfactory and covers more of low rain fall risk than the high rainfall risk.

The role of parents during the pandemic is needed in building of children's character at home. Character education in online learning can be doing by implementing the three slogans of Ki Hadjar Dewantara, namely, ing ngarso sung tulodo, ing madyo mangunkarso, and tut wuri handayani. Ing ngarso sung tulodo is the role of parents that can being an example for their children, ing madyo mangunkarso is the role of parents in providing enthusiasm for their children in learning at home, and tut wuri handayani is the role of parents in encouraging children in learning process. The pattern of character education by applying that three slogans is also harmonized which the teachings in Hindu religious literature. By using the literature study method, this paper uses references from various sources, namely journals, books, Hindu literary works, and the internet. By a literature study was found that Hindu literature sources have taught parents in educating children, from an early age to adulthood. Based on the Hindu literature, can be harmonized through the three slogans of Ki Hadjar Dewantara during online learning at home in bulding the character during the pandemic.

as action research that promote research-participant partnerships and theories such as feminism that encourage attention to values such as empowerment, agency, and equity in our technological designs. Being at the intersection of the human and technological experience gives us unique and important protection against future, but currently unimagined, uses? Second, this repurposing of data about people by corporations leads to new resources. For example, could this new location information be combined with other sources (e.g., census data about average income by zip code) to customize service offerings? How much are our movements and locations worth to other corporations? This repurposed data creates new resources and opportunities for the corporation, but what does it mean for the customer? Third, what does it mean when only corporations can analyze big data? This research was made possible only through access to corporate CDR data. We might argue that this data is the privilege of corporate researchers and those who collaborate with them or could purchase the assets. But like others, I see a potential research divide between those with access, who then control the agenda and produce its knowledge (including what gets analyzed and does not), and those without [2]. As a research community, should we discuss strategies for mitigating the potential divide? More generally, this study raises new questions about the relationship between the researcher and the researched and highlights the role of the corporation in that process. What should HCI do? Our commitment to the human experience has long required us to be mindful of participants' rights. More recently, we have focused Big data is being positioned as a research agenda within HCI. But I confess that I'm troubled by developments in the relationship between people (and their data, and as data) and the algorithms of big data analysis. A recent Communications article repurposed cellular telephony call detail records (CDRs) to determine hundreds of thousands of people's average commutes, carbon footprints, and locations [1]. The authors cited the prohibitive costs of collecting this data using traditional methods as justification for repurposing CDRs. While not conducted by HCI researchers, this report focuses on topics of interest to us: mobility and sustainability. It raised three concerns for me. First, the repurposing of records separates the original rationale for data collection from the intent of the current algorithmic analysis. The customers, whose data was originally collected for billing and network-traffic-management purposes, participated in a study in which their data was transformed into information about their location and movements. They were not required to give their consent to participate, but should they have been? The authors describe efforts to anonymize the data, but this is difficult to do. Should participants have any ability to control the algorithms that generated this data (e.g., to make them not run on the human-identifiable data)? Further, should participants have the ability to prevent their data from being repurposed without their consent, a A Big Data Confession


Cattle production is the single largest segment of U.S. agriculture. Animal disease, whether a single incident or a full-scale outbreak, can result in significantly restricted access to both foreign and domestic markets. Regaining consumer confidence is difficult. If a disease cannot be traced back to a common source, then only time can tell whether or not eradication and containment efforts have been successful. Simply "waiting it out" can result in long-term economic losses on a National scale especially when diseases which are prone to epizootic outbreaks or those with long incubation periods are involved.
The United States Department of Agriculture (USDA) maintains that traceability is the key to protecting animal health and marketability: The National Animal Identification System (NAIS) is a voluntary disease traceability framework released by the USDA. Many of the efforts surrounding the development of the NAIS have encompassed the identification of livestock production and handling premises as well as individuals or herds of animals, whereas little effort has been directed toward the ultimate goal of animal traceback in 48 hours.
In this dissertation, computational science is applied to the problem of animal disease traceability. In particular, a computational model is developed for the purpose of conducting large-scale traceability simulations. The model consists of two components; the first being a parallel, Monte Carlo discrete events simulator capable of generating large, NAIS-compliant, mock datasets representative of the processing requirements of actual NAIS data. The second component is a large-scale, parallel disease tracing algorithm that is mapped onto an SMP supercomputer where high-performance is achieved by adopting a hybrid parallel programming model that mixes a shared memory multi-threading model (OpenMP) with a distributed memory message passing model (MPI).
The objectives of this dissertation are to characterize the computational requirements of the NAIS, identify computational platforms and programming paradigms well suited to this effort, and to identify and address computational performance bottlenecks associated with large-scale tracing algorithms.


The concept of internet of things, or IoT as it is popularly referred to, came into being when it was discovered that it is possible for computers to communicate with devices ranging from simple home appliances to industrial machinery and equipment without the need for any human intervention. The fact that IoT makes it possible for computers to simplify manufacturing processes and bring about a radical change in our daily lives, making this technology an important step forward and in tandem with cloud computing. In this chapter, the authors discuss the contributions that IoT can make in construction industry. With IoT it is possible for a machine to let a remote computer know from any part of the world its current status and physical disposition. For construction firms that need to operate machinery and equipment in distant locations, IoT makes it possible to collect monitor and manage in real-time.


We report a first experimental observation of two-wavelength switching (2WS) and bistability with a 1310nm-Quantum Dot (QDot) Distributed Feedback (DFB) laser subject to external optical injection and operated in reflection. We experimentally demonstrate the switching of the emission wavelength of the QDot laser when an external optical signal is injected into one of the subsidiary longitudinally modes located in the longer wavelength side of the device's lasing mode. Clockwise nonlinear switching and bistability are attained in all cases for both the emitting and the injected mode of the QDot laser as the injection strength is increased. Moreover, very high on-off contrast ratio is measured in the switching (and bistability) transition of the emission mode of the device. We have also analysed the switching properties of the 1310-QDot DFB laser as a function of the applied bias current and the initial wavelength detuning between the wavelengths of the external signal and that of the device's injected mode. In general, wider bistable loops, higher on-off contrast ratio between output states and higher input power requirements for switching are observed as the applied bias and initial detuning are increased. This diversity of switching behaviors obtained with a 1310 QDot DFB laser under external optical injection, added to the theoretically superior properties of nanostructure lasers, offers exciting prospects for novel uses of these devices in all-optical logic and all-optical switching/routing applications in present and future optical telecommunication networks.

The IEEE 802.15.4/ZigBee attracts much attention as an energy-efficient and flexible low-rate wireless protocol for ubiquitous networks. This paper proposes a new active period assignment method called Time Shift Grouping Access (TSGA) in IEEE 802.15.4/ZigBee beacon mode for cluster-tree networks. By dividing top-level routers into two groups and using different time slots for accessing PAN coordinator, throughput bottleneck in Contention Access Period (CAP) is reduced. Beacon frame collision between subnets is also avoided by introducing different long spreading codes. Thus, low power intermittent operation with beacon is possible in each subnetwork. Simulation results show that the proposed method presents a better network throughput and reduces energy consumption by 1/2 to 1/3.


Examines the conductivity of two-dimensional weakly disordered systems. It is shown that in a two-dimensional system there is a divergence as 1/q in the probability for an electron to diffuse from a state K to a state K+q, and that this is the origin of the logarithmic term. The method enables the authors to examine the nature of the 'localisation' which occurs. The wavefunctions fall off as 1/r and at zero temperature and for an infinite specimen cannot be normalised. At finite temperatures inelastic collisions give a cut-off at a finite distance, which decreases with increasing T, but overlapping states near the Fermi energy are separated by energies small compared with kT, so conduction is essentially metallic. The logarithmic term depends on the normalisation factor.


The invention discloses a portable quick detection method for pathogenic bacteria. The portable quick detection method comprises the following steps: step 1, adding magnetic beads into a to-be-detected substance, putting the to-be-detected substance into a heating groove, heating the to-be-detected substance at a constant temperature through a constant temperature control unit, putting a nucleic acid extraction module into the to-be-detected substance, and sucking out the magnetic beads adsorbing nucleic acid according to magnetic regions of the nucleic acid extraction module; step 2, heating the to-be-detected substance through a heater; step 3, emitting laser by a laser emitter, enabling laser to pass through laser via holes and irradiate on the to-be-detected substance, enabling a laser sensor to receive the laser from the laser via holes, analyzing the laser through a control circuit board, and displaying detection data of the to-be-detected substance on a display module. The portable quick detection method is economical, portable, and accurate and efficient in detection.

Summary Information is given on dates of sowing and mid-silk for Inra 200 in 40 experiments (two each year at Oxford, 1962–75, and at Cambridge, 1970–5), together with cumulative temperatures between these dates. Two methods of defining effective temperature for maize development have been considered, namely the method advocated by U.K. Meteorological Office with 10 °C as the base temperature (the Ag. Met. method) and that defined in Ontario units. The regression relation between accumulated temperature and dry-matter content of the grain during ripening has also been calculated, from data obtained in the years 1966–74, and assessments made of cumulative totals in Ag. Met. day °C and in Ontario units from the date of silking until the grain D.M. content is 40%, when the crop is considered suitable for ensiling, and from silking until grain D.M. content is 60%, when the crop may be considered ripe. Cumulative temperature totals were significantly more stable over experiments than time expressed in calendar days. Totals of Ontario units were less variable than totals of Ag. Met. day °C. Estimated requirements for Inra 200 were 405 day °C or 1380 Ontario units from sowing to mid-silk, 255 day °C or 800 Ontario units from silking to 40% D.M. in the grain (for silage crops), and 380 day °C or 1235 Ontario units from silking to 60% D.M. in the grain.


Cubic gallium nitride (GaN) is a wide bandgap semiconductor that exhibits a high crystallographic symmetry resulting in a lower inbuilt polarization which is useful for more efficient phosphor-free green light-emitting diodes. It has been grown using molecular beam epitaxy (MBE) and metal-organic chemical vapor deposition (MOCVD), which produce highly ordered thin films on compatible substrates. In this work, we report the chemical synthesis of GaN using chemical metathesis reaction in diethyl ether with lithium nitride and anhydrous gallium chloride as precursors, inside a nitrogen glove box at the room temperature. The resulting product was subsequently washed to remove lithium chloride and dried before vacuum annealing in a furnace at 850°C. Powder X-ray diffraction (XRD) scans of the as-prepared and annealed product reveal a mixed phase of GaN along with Ga_2O_3. Energy dispersive X-ray spectroscopy (EDAX) measurements show a nitrogen-poor product, which correlates well with the nearly black color of the powder. Diffuse reflectance spectroscopy (DRS) measurements were carried out with the obtained product on a barium sulfate substrate in a Perkin-Elmer Lambda 1050-UV-Vis-NIR spectrophotometer showing a strong absorbance below 400 nm. The energy band gap is bounded by values extracted from the Tauc plot and DRS measurements in the range of 3.2-3.5 eV, which is in good agreement with the known excitonic bandgap of cubic GaN (∼ 3.3 eV). Initial photoluminescence (PL) measurements using a Perkin-Elmer LS-55 spectrophotometer with an excitation wavelength of 310 nm reveal a weak emission centered around 440 nm corresponding to the known defect centers (D^0X) in GaN. Further development of this process to form inks is expected to provide an alternate pathway to producing flexible phosphor-free lighting devices.


AbstractHydrographic data obtained by high-resolution shipboard observations and Argo profiling floats have been analyzed to study the mesoscale structure and circulation of the North Pacific Subtropical Mode Water (STMW). The float data show that in the late winter of 2008, STMW having a temperature of approximately 18.8°, 17.7°, and 16.6°C formed west of 140°E, at 140°–150°E, and east of 150°E, respectively, in the recirculation gyre south of the Kuroshio Extension. After spring, the newly formed STMW gradually shift southward, decreasing in thickness. Simultaneously, the STMWs of 16.6° and 17.7°C are gradually stirred and then mixed in terms of properties. In late fall, they seem to be integrated to form a single group of STMWs having a temperature centered at 17.2°C. Such STMW circulation in 2008 is much more turbulent than that in 2006, which was investigated in a previous study. The difference between the two years is attributed to the more variable state of the Kuroshio Extension in 2008, associate...

We explore efficient transformation of structure-borne propagating waves into low-power electricity using patterned polymer piezoelectrics integrated with an elastoacoustic mirror configuration. Fourier transform-based spatial optimization of a piezoelectric energy harvester domain weakly coupled to a thin plate housing a continuous elliptical elastoacoustic mirror is presented. Computational modeling and experimental testing are employed to quantify performance enhancement in power generation using the presented approach. Excellent agreement is observed between numerical simulations and experimental measurements. Specifically, dramatic enhancement of the harvested power output is reported by patterning the electrodes of a rectangular polyvinylidene fluoride piezoelectric energy harvester in the elliptical mirror domain.


This Study analyzed the electric car effect on the Korea Expressway System in terms of year 2020 emission. The analysis was based on the green car dissemination goal by the government and year 2010 emission statistics. Major contents performed in the study area were as follows. First, the greenhouse gases emitted from the highways were found to be approximately 17.3 million tons of as of 2010. Analysis showed the emission would be 17.4 million tons in 2015 and 16.2 million tons in 2020. The results in the pattern reflect the effect of O/D on the KTBD and the trend of traffic increase from 2015 to 2020 followed by decrease in 2020. Second, in the case of greenhouse gas emission with the anticipated supply of electric cars, the amount of emission in 2015 will be 17.1 million tons, which is about 2.0% reduction compared to the lack of introduction of electric cars. The analysis also showed that in 2020, the amount of emission will be 14.2 million tons, which indicates the effect of reduction is 12.8% compared to non implementation of the program.


We identify a surface within the NASA Phoenix landing site Area D characterized by boulder‐topped, polygonally‐patterned mounds comparable in radius and cross‐sectional morphology to terrestrial sublimation polygons found in Antarctica. Both Martian and Antarctic polygons display topographic asymmetry, with shallow equator‐facing slopes and steep pole‐facing slopes, interpreted to indicate insolation‐dependent, differential sublimation of buried ice. On the basis of morphological similarities, we classify the Phoenix Box 1 polygons as sublimation polygons. Terrestrial sublimation polygons form where ice volumes exceeding available pore space occur in the shallow subsurface and where near‐surface conditions are too cold and dry to permit the development of saturated active layers: conditions comparable to those recently modeled for Mars in the Phoenix landing site Area D, Box 1. The identification of sublimation polygons on Mars would provide direct evidence for shallow, ground ice exceeding pore‐ice volumes and shed light on the emplacement mechanism of this ice.

In this work, a novel mechanochemical-assisted extraction (MCAE) coupled with the ultra-high performance liquid chromatography (UHPLC) method was developed to extract two alkaloids with solid acids from Stephania tetrandra S. Moore. To further understand the influence of extraction parameters on the MCAE process, the response surface methodology was applied for systematic investigation. The results showed that the highest yield of alkaloids was obtained within 15 min of the total extraction time under the optimal conditions: oxalic acid (20 wt %), grinding plant materials for 5 min, and the liquid/solid ratio of 20 mL/g. Mechanochemical treatment resulted in the destruction of cell walls and increased the total contact surface area due to the smooth surface changing to an open porous structure. Accordingly, the developed extraction method showed advantages of being more ecofriendly, faster, and more efficient than conventional extraction methods. Meanwhile, the extractant was analyzed by UHPLC. The obtain...


The professionals involved in transport and land-use planning have a strong relationship with statistics representing travel behaviour. Even if not directly conducting the surveys, they will certainly wish to use data at some point of time, and at that stage they will realize what should have been done in the design and administration phases of the survey. The combination of land-use activity and a transport system invariably results in trip-making, and to measure the type and extent of trip-making it is necessary to conduct travel pattern surveys by one mean or other. The travel patterns may be described in terms of who is going where, with whom, at what time, by which mode and route, and for what purpose. The measurement of such travel patterns is perhaps the unique part of transport survey methods, but determining the most effective way of obtaining this information has often received little attention.


Cobalt ferrite nanopowders are the subject of much interest due to their unusual optical, electronic and magnetic properties compared to their bulk counterparts. These properties, along with their physical and chemical stability, make them suitable for applications in magnetic recording, as magnetic fluids and for magnetic drug delivery. This work focuses on the influence of chelating agents, namely polyvinyl alcohol (PVA) and citric acid (CA), on the microstructure and antibacterial property of cobalt ferrite nanopowders. The microstructure, elemental composition, and chemical structure were characterized using scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDX), and Fourier transform infrared (FTIR) spectroscopy, respectively. Phase analysis of cobalt ferrite nanopowders was performed via X-ray diffraction (XRD). Moreover, thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC) were performed to determine the temperature at which the decomposition and oxidation of the chelating agents take place. The wetting characteristics of cobalt ferrite nanopowders were determined using a water contact angle (WCA) measurement. The antibacterial properties of cobalt ferrite nanopowders were investigated. The results indicate that chelating agents influence strongly the structure, particle size distribution and antibacterial property of nanopowders.


Ageism, which is defined as discrimination on the grounds of age, is a negative phenomenon which becomes increasingly problematic every year because of the perception of young and active people as more desirable than elderly people. As a result, the latter are pushed to the peripheries of social life and, in most cases, they face social exclusion. The Guidelines of the 2014–2020 Long-term Senior Policy ( Zalozenia Dlugofalowej Polityki Senioralnej w Polsce na lata 2014–2020 ) are the important element of the struggle against ageism. All state institutions apply them in projects which secure and support the activity of seniors. Various initiatives and forms of senior support organized in the city of Lublin are presented in the article.


Ln 48-49 – "... suggest that peatland permafrost is more abundant along the coast than in the interior". This seems to be an important point. Does this study confirm this suggestion? Does the study adequately cover the interior peatlands, or focus primarily on the coast? Despite an underestimation of the coastline peatlands, does this study conclude that permafrost is more abundant along the coast than within the interior?

Clear experimental evidence of charge density wave correlations competing with superconducting order in YBCO have thrust their relationship with the pseudogap regime into the spotlight. To aid in characterizing the pseudogap regime, we propose a dimensionless ratio of the diamagnetic susceptibility to the correlation length of the charge density wave correlations. Using Monte Carlo simulations, we compute this ratio on the classical model of Hayward et. al. (Science 343, 1336 (2014)), which describes angular fluctuations of a multicomponent order, capturing both superconducting and density wave correlations. We compare our results with available data on YBa$_2$Cu$_3$O$_{6+x}$, and propose experiments to clarify the value of this dimensionless ratio using existing samples and techniques.


The most exotic neutron-proton asymmetric nuclei are produced most efficiently in high-energy fragmentation reactions. These exotic nuclei are produced as fast secondary beams with energies of order 100 MeV per nucleon or greater, and hence v/c > 0.3, often with relatively low intensities. For such beams one can exploit both the detection efficiency and the cross sections for fast one- and two-nucleon removal reactions. The reaction dynamics of these channels is relatively simple due to the fast (sudden), surface grazing, and forward travelling (eikonal) nature of the reaction mechanism. More recent work now interfaces these sudden, eikonal reaction models with more microscopic nuclear structure model input. The possible roles of nucleon and pair correlations and their observation using such reaction data are discussed.


In recent researches, many approaches based on association rules have been proposed to improve the accuracy of recommender systems. These approaches are primarily based on Apriori data mining algorithm in order to generate the association rules and apply them to improving the recommendation results. However, these approaches also reveal some disadvantages of the system, such as taking a longer time for generating association rules; applying the Apriori algorithm on rating sparse matrix resulting in irrelevant information and causing poor recommendation results to target users and association rules generated primarily relying on given threshold of Support and Confidence measures leading to the focus on the majority of rules and ignoring the astonishment of rules to affect the recommendation results. In this study, we propose a new model for collaborative filtering recommender systems: The collaborative recommendation is based on statistical implication rules (IIR); Differently from collaborative recommendation based on association rules (AR), the IIR predicts the items for users based on statistical implication rules generated from rating matrix and Implication intensity measures measuring the surprisingness of rules. To evaluate the effectiveness of the model, in the experimental section, we implement the model on three real datasets and compare the results with some different effective models. The results show that the IIR has higher precision on the experimental datasets.


Background A smartphone image recognition app is expected to be a novel tool for measuring nutrients and food intake, but its performance has not been well evaluated. Objective We assessed the accuracy of the performance of an image recognition app called CALO mama in terms of the nutrient and food group contents automatically estimated by the app. Methods We prepared 120 meal samples for which the nutrients and food groups were calculated. Next, we predicted the nutrients and food groups included in the meals from their photographs by using (1) automated image recognition only and (2) manual modification after automatic identification. Results Predictions generated using only image recognition were similar to the actual data on the weight of meals and were accurate for 11 out of 30 nutrients and 4 out of 15 food groups. The app underestimated energy, 19 nutrients, and 9 food groups, while it overestimated dairy products and confectioneries. After manual modification, the predictions were similar for energy, accurately capturing the nutrients for 29 out of 30 of meals and the food groups for 10 out of 15 meals. The app underestimated pulses, fruits, and meats, while it overestimated weight, vitamin C, vegetables, and confectioneries. Conclusions The results of this study suggest that manual modification after prediction using image recognition improves the performance of the app in assessing the nutrients and food groups of meals. Our findings suggest that image recognition has the potential to achieve a description of the dietary intakes of populations by using "precision nutrition" (a comprehensive and dynamic approach to developing tailored nutritional recommendations) for individuals.

Luminescent materials with an efficient single-(pure) color up-conversion luminescence (UCL) are expected to be applied to three-dimensional(3D) display, lighting, biological imaging, promoting plant growth and improving the photoelectric conversion efficiency of solar cells. In this work, perovskite-type KMnF3 fluoride nanocrystals (NCs) are grown in situ in a fluorosilicate glass co-doped with rare earth (RE) ions Yb3+/Er3+ by a controlled thermal treatment. Compared with precursor glass (PG), the nano-glass composites (also referred to as glass ceramics, or GC in short) thus obtained exhibit a significantly enhanced (by 6 times) red UCL emission. Although a weak green UCL emission can be also observed in the GC, the intensity ratio of the red UCL emission to green UCL emission is as high as 30, implying a good color purity. It is suggested that the dramatic enhancement of UCL emissions in the GCs is due to the doping of RE ions into the KMnF3 NCs with a much lower phonon energy (330 cm–1) than that of the silica glass matrix about 1100 cmv1. However, the doping mechanisms of RE ions into KMnF3 nano-glass composites are not yet conclusive, mainly because of the charge and ionic radius mismatch between RE ion dopants and cations of KMnF3. This work combines the high-resolution transmission electron microscopy (HR-TEM) analysis technology and the first principles calculation, to unravel the doping mechanism of RE ions in KMnF3 nano-glass composites. First, the HR-TEM study provides straightforward evidence that RE ions are preferentially accumulated in KMnF3 NCs embedded in the glass matrix. Then, through the first-principles calculation considering the charge balance, it is found that the formation energy of RE ions substituting for K+ is lower than for Mn2+ lattice sites in KMnF3, which is most likely related to the fact that the ionic radius of the eight-fold coordinated K+ is larger than that of the six-fold coordinated Mn2+ and thus is more conductive to accommodating the large size RE ions. The electronic densities of states at the top of the valence band and the bottom of the conduction band of KMnF3 increase after doping the RE ions. It is inferred from the profile of partial density of state that RE ions have a strong bonding tendency with F- in the crystal. Benefiting from the efficient energy transfer between RE ions and Mn2+ in KMnF3, the green UCL emission is dramatically quenched, and consequently, the GC is endowed with a highly pure red UCL emission. The present study is expected to deepen the understanding of RE ions doping mechanisms in NCs and facilitate the design of highly efficient UCL materials based on nano-glass composites.
