Fusarium wilt was recorded in line DK 247 treated with Biospectrum BT – 8.9%. Corn borer infestation was reduced by Trichopsin BT and Biospectrum BT, which have both insecti-cide/fungicidal and growth-stimulating effects. The reduction in the incidence was 2.3–2.8%, depending on the genotype of the lines. Treatment with biologicals improved the cob structure of the studied lines. Trichopsin BT and Biospectrum BT had the greatest effects on the cob pa-rameters. Due to Biospectrum BT, the cob length increased by 5.2–6.7%, the cob diameter – by 2.0–4.9%, and the cob grain weight – by 3.0–7.1%. The results of measurement of the yields from the parents (maize lines) showed that under irrigation the average performance of the studied maize lines ranged 3.75 to 6.11 t/ha, depending on the genotype of the lines (factor A) and the use of biologicals. Conclusions. It was found that biologicals Fluorescein BT, Trichopsin BT, and Biospectrum BT reduced the damage to maize lines induced by blister smut, Fusarium wilt, and corn borer by 0.9–4.2%. Treatment with Biospectrum BT ensured the highest grain yields from the maize parent, which averaged 4.63 t/ha, the gain in the yield was 0.44 t/ha or 10.5%. Treatment with Trichopsin BT had a positive effect on the yield, which averaged 4.54 t/ha, providing a gain in the yield of 0.35 t/ha or of 8.4%. Treatment with Fluorescein BT increased the yield by 0.14 t/ha or by 3.3%. Biospectrum BT was the most effective agent, which provided a significant reduction in the damage to the maize lines caused by fungal diseases and pests. On the basis of the processed scientific papers, information was summarized regarding the biological characteristics of pollination and the formation of full-fledged seeds of Medicago sativa L. as an important forage entomophilous-cross-pollinated crop. Despite the high potential due to the biological characteristics of alfalfa, it is problematic to obtain a high yield of seeds, depending on the structural features of the flower, pollination, the passage of the embryonic period of ontogenesis and weather conditions during the flowering period. The main reasons that affect the degeneration of seed buds are given. The ways of increasing the seed productivity of alfalfa varieties are proposed, in particular, a preliminary assessment, as well as selection, of the initial breeding material for the elements of seed productivity and the level of manifestation of autogamy.

Quantum dots (QDs) have attracted significant interest in nanoscience since the early 1990s. They have also been studied intensively in the first decade of the new century because of their potential for use in electronic applications such as field-effect transistors, photodetectors, displays, and photovoltaic cells. Because of their very small size, 3D-confined QDs have a large Bohr radius, which allows tuning of their optical properties as a function of size to target specific regions of the solar spectrum. They can also produce multiple excitons by absorbing a single photon, which could enable development of highly efficient photonic devices.1 We recently demonstrated near-IR photodetectors using various QD/polymer composites. One approach to enhance device performance is through conduction boosting by incorporation of pentacene into lead selenide (PbSe) QD/poly(vinyl carbazole) (also known as PVK) photodetector devices. Our results show that the device's external quantum efficiency can be improved by simply blending the pentacene.2 Similarly, we used polypyrrole and single-walled carbon nanotubes (SWCNTs) as conduction boosters instead of pentacene. We maximized the photodetection efficiency of devices containing SWCNTs by chemically attaching the PbSe QDs to SWCNTs.3, 4 To further investigate the significance of QDs, we focused on their inorganic chemistry because the bulky ligand surrounding the QDs plays an important role in the charge transport in the structure.5, 7 We developed photo-patternable QD arrays with enhanced conducting properties by incorporating stimuliresponsive ligands in the QD structure. We stabilized the QDs Figure 1. (a) Overview of photocleavage of tert-butoxycarbonyl (t -BOC)-protecting groups. h : Photon energy. QD: Quantum dot. : Heating.

We suggest a new terminology, reasonable tradeoff parameters in a fixed tradeoff algorithm. In brief, if there is no other set of parameters which is a comparative advantage in terms all of the tradeoff efficiency, the cost of pre-computation and the probability of success, we call it a reasonable set of parameters. And the criterion for tradeoff parameters being reasonable is also obtained. As an additional corollary, it is showed that if one of the tradeoff efficiency, the cost of pre-computation and the probability of success is given with the table count l in the rainbow tradeoff (instead, with the matrix stopping constant in the Hellman and the DP case), the remaining ones are uniquely determined and tradeoff parameters implementing these values always exist. The concept of reasonable tradeoff parameters is extended to the case of comparing two sets of parameters from two different tradeoff algorithms respectively. Under assumptions typically considered in theoretical discussions, we conclude that in the range of the high value of the probability of success, we get reasonable tradeoff parameters by selecting the rainbow tradeoff only. And the method to get these reasonable tradeoff parameters is obtained.


Recent experimental studies showed that the access resistance (AR) of a nanopore with a low thickness-to-diameter aspect ratio plays an important role in particle translocation. The existing theories usually only consider the AR without the presence of particles in the pore systems. Based on the continuum model, we systematically investigate the current change caused by nanoparticle translocation in different nanopore configurations. From numerical results, an analytical model is proposed to estimate the influence of the AR on the resistive-pulse amplitude, i.e., the ratio of the AR to the pore resistance. The current change is first predicted by our model for nanoparticles and nanopores with a wide range of sizes at the neutral surface charge. Subsequently, the effect of surface charges is studied. The results show that resistive-pulse amplitude decreases with the increasing surface charge of the nanoparticle or the nanopore. We also find that the shape of the position-dependent resistive-pulse might be distorted significantly at low bulk concentration due to concentration polarization. This study provides a deep insight into the AR in particle-pore systems and could be useful in designing nanopore-based detection devices.


Non-point and diffuse sources can be the most significant sources of pollutants in a watershed. Atmospheric deposition in its three forms (ambient, dry, and wet) has often been neglected and thus was not included in watershed approach for water resources management. Often regulatory frameworks for water resources protection have not taken into account atmospheric deposition because little or no data is available. The project undertaken is new and unique in its scope and approach to monitor and measure pollutants in atmospheric deposition and its impact on storm water quality within a river watershed. Specialized sampling equipment and ultra-clean analytical methodology were employed to quantify the concentrations or masses in ambient air, precipitation, and runoff for twelve trace metals. These metals include mercury (Hg), cadmium (Cd), antimony (Sb), aluminum (Al), arsenic (As), chromium (Cr), copper (Cu), manganese (Mn), nickel (Ni), lead (Pb), vanadium (V), and zinc (Zn). Meteorological parameters including wind speed, wind direction, temperature, and relative humidity were also measured. This study represents the most complete set of atmospheric concentration and deposition data for trace metals and mercury in an urban watershed at this time. Additionally, this is the first time that mercury together with other trace elements in dry deposition and runoff has been measured in a study of this length. The results of this study provide both the critical information and valuable study approaches to monitor trace metal deposition in urban watersheds.


Transforming growth factor beta (TGFbeta) plays a critical role in connective tissue remodeling by fibroblasts during development, tissue repair, and fibrosis. We investigated the molecular pathways in the transmission of TGFbeta signals that lead to features of connective tissue remodeling, namely formation of an alpha-smooth muscle actin (alpha-SMA) cytoskeleton, matrix contraction, and expression of profibrotic genes. TGFbeta causes the activation of focal adhesion kinase (FAK), leading to JNK phosphorylation. TGFbeta induces JNK-dependent actin stress fiber formation, matrix contraction, and expression of profibrotic genes in fak+/+, but not fak-/-, fibroblasts. Overexpression of MEKK1, a kinase acting upstream of JNK, rescues TGFbeta responsiveness of JNK-dependent transcripts and actin stress fiber formation in FAK-deficient fibroblasts. Thus we propose a FAK-MEKK1-JNK pathway in the transmission of TGFbeta signals leading to the control of alpha-SMA cytoskeleton reorganization, matrix contraction, and profibrotic gene expression and hence to the physiological and pathological effects of TGFbeta on connective tissue remodeling by fibroblasts.


A combined kinetic and clinical study showed that rifampicin displays good tissue diffusibility, though it may have a tendency to accumulate. A liquor transfer sufficient for the bacteria most commonly responsible for meningeal inflammation was observed; 15/18 cases of purulent bacterial meningitis treated were clinically cured without sequelae, while 1 displayed considerable improvement. Two patients died from unforseen, uncontrollable complications that were not related to administration of the drug.


A biologically-inspired top-down learning model based on visual attention is proposed in this paper. Low-level visual features are extracted from learning object itself and do not depend on the background information. All the features are expressed as a feature vector, which is looked as a random variable following a normal distribution. So every learning object is represented as the mean and standard deviation. All the learning objects are combined as an object class, which is represented as class's mean and class's standard deviation stored in long-term memory (LTM). Then the learned knowledge is used to find the similar location in an attended image. Experimental results indicate that: when the attended object doesn't always appear in the background similar to that in the learning objects or their combinations change hugely between learning images and attended images, our model is excellent to the top-down approach of VOCUS and NavaIPakkam's statistical model.

Abstract Upernavik Isstrøm, a marine glacier undergoing rapid retreat, is simulated by forcing a numerical model with ocean-driven melt. A review of processes driving retreat led us to hypothesize that a glacier undergoing rapid retreat may be less sensitive to perturbations in the balance of forces than a glacier that is undergoing moderate changes or a glacier in steady state. Numerical experiments suggest this is not the case, and that a system in rapid retreat is as sensitive to basal traction perturbations as a system that is near to steady state. This result is important when considering other glacier systems experiencing marine-forced retreat. While the ice–ocean interface is of primary importance, additional perturbations from meltwater-forced decoupling of the glacier from its bed continue to feature in glacier dynamics.


In this paper, we propose a two-stage CNN-based framework to learn color names from web images, aiming to predict color names for tiny image patches. To deal with the noisy labels widespread in web images, we propose a self-supervised CNN (SS-CNN) model in the first stage. The SS-CNN model is trained on image patches with their own color histograms as supervision information. Thus its outputs are able to reflect the color characteristics of images without the influence of the noisy labels. In the second stage, we finetune the SS-CNN model to learn the mapping from image patches to color names, where the patch labels are inherited from its father images. Besides, sample selection is imported iteratively in turns with the finetuning process, which helps filtering out some noisy samples and further improves the model accuracy. Our model shows high representation ability to colors and achieves better performance of color naming compared with the state-of-the-art methods.


AL amyloidosis (AL) is a malignant form of plasma cell dyscrasia (PCD). It is insidious, and its end‐organ damage can mimic that of common diseases. At diagnosis, routine tests for monoclonal protein are insufficient for the differential diagnosis. We hypothesized that Hevylite® (HLC) isotype patterns may help discriminate between AL and benign PCD states.


Research background: One of business cycles stylised facts is that contractions are shorter than expansions, but less persistent, more volatile, and therefore asymmetric. Investigating existence and type of business cycles asymmetry is important for analysis of economic policy and statistical modelling. Economic implication of business cycles asymmetry is that economic policy should be different in a period of contractions than in one of expansion. Statistical implication is that linear models of business cycles cannot capture this stylised fact. Purpose of the article: The article has two objectives: extend the literature on the business cycles asymmetry by testing data from 36 European countries including countries never been analysed before and test robustness of the results to extraction methods and asymmetry tests used. Methods: Quarterly GDP series from Eurostat database covering period 2000q1–2016q3 were used with two exceptions. In the case of Bosnia and Herzegovina and Montenegro quarterly industrial productions indexes were used. Series were prepared by removing seasonal component using X13-ARIMA procedure. To assess robustness of asymmetry tests results to alternative methods of detrending business cycles were extracted using two filters: Corbae-Ouliaris ideal band filter and double Hodrick-Prescott filter. For testing the deepness and steepness asymmetry of the business cycles three tests were used: Mills, Mira and Sichel tests. Findings & value added: Weaker evidence of deepness asymmetry was found in Cyprus, Montenegro and Turkey cycles, where all three tests statistics for both filters have a negative sign. However, only for one of the tests in each country the result was statistically significant. For two other countries, Germany and Sweden, four out of six tests indicated deepness asymmetry, but only one of these tests results was statistically significant. Most of the cycles show steepness asymmetry, with the exception of Ireland business cycles, and to a certain extent cycles of Poland, Malta, Montenegro and Spain.


The effects of deformation on electronic heat capacity of different elemental metals were computed and studied based on Einstein model formalism. The electron density parameters of deformed metals under the application of different strains were obtained for different metals. The poison ratio relating the transversal compression to elongation in the direction of applied deformation for different elemental metals were computed base on elastic moduli for homogeneous isotropic material and used in this work. The results obtained revealed that there is a good agreement between the computed and experimental values of electronic heat capacity of metals. This shows that Einstein model can be used in the theoretical prediction of heat capacity of metals. The result obtained revealed that the electronic heat capacity of metals are more concentrated in the high density region than the low density region. This seems to suggest that the electronic heat capacity of metals depend on the electronic concentration. Also, the experimental value of electronic heat capacity is higher than the computed value, this could be due to some factors that the electronic heat capacity of metals depend upon that the model does not take into consideration. The result obtained shows that the electronic heat capacity of metals increases as the temperature increases. The electronic heat capacity of all the metals increases with an increase in deformation (strain). This could be due to the fact that as deformation increases, the collision between the interacting electron increases which forces the mean atomic velocity, amplitude of atomic vibration and electron thermal excitation to increase and there by result in the increase in the electronic heat capacity of the metals as deformation increases.

More than ever, supply chain security requires unprecedented attention. This report of security strategies in supply chains expatiates on the recent trend and appeals to analyze why security strategies have received more attention throughout supply chains in recent times and discusses how strategies can be implemented along the total supply chain to make it more secure. Meanwhile, what are some of the impacts to the supply chain members is also be of concern.


This investigation sought to study the phenomenological experience of participation in a Celtic folk dance class and to determine the relationship between participation in an exercise program based on Celtic folk dances and stress reduction. This research was conducted as part of the Northern Interior Health Region Women's Mid-Life project which is part of the B.C Women's Health in Mid-Life Project (WHIM). A dual methodological approach descriptive phenomenology and quantitative testing was used to investigate the indepth experience o f midlife women participating in a beginner level Celtic folk dance class. Women (n=2S) ages 33 to 65 participated in seven introductory level classes based on Scottish Country Dances and Irish Set Dances. Participants completed a demographic questionnaire during the first class. The 40 item Speilberger's State Trait Anxiety Inventory-Form Y (STAI), a commonly used instrument in research on exercise and stress, was completed preand postclass during the first and sixth weeks. Feedback firom the participants (n =17) on the STA^ results was obtained during a group activity conducted at the beginning of the seventh class. All participants also filled in a brief guided journal after each class. Five women who fit predetermined criteria — 1) age 45 to 65,2) present for at least 6 o f the 7 classes, and 3) indicated above average stress levels on the preliminary questionnaires participated in audiotaped interviews designed to explore their phenomenological experience of the dance classes. Phenomenological analysis of the interviews, guided journals and group activity yielded a thematic structure around the two core themes "Increase in Stress" ("Social Stress", "Stress from the Dancing","Extemal Stress", "Challenge") and "Decrease in Stress''! "The Group o f Women", "Movement and Music", "Change o f Focus","Fun and Laughter"). The core phenomenon that emerged was described, in the voice o f one o f the women as, "A Little Bit of Weight is Taken O ff'. Two other themes emerged as keys to balancing and managing the stress implicit in the dance class, "New Learning and Mastery" and "Leadership". The researcher proposes that participation in a physical activity program, based on Celtic folk dances, is a potentially effective method for managing stress.

In this paper a procedure is proposed for determination of heat load under high temperatures. The procedure proposed allows finding temperature of a surface heated by a gas burner flame which is necessary to assure the accuracy of further research of temperature fields and stress-strain state of products. The discussed problem is about determining surface temperature of an optical fiber billet made of quartz glass placed within heating zone of a gas burner and also further research of temperature fields within the billet in course of a production process. Method of determining surface temperature of a billet in a gas burner heating zone includes conducting an experiment to measure temperature in a number of points away from the burner flame and subsequent solving of an optimization problem to calculate the temperature of a surface within heating zone. In the course of experiment surface temperature of a tube was measured by two thermocouples at a distance from the heating zone which was followed by solving an optimization problem. As the target function, sum of squares of deviations of calculated temperature values at given points from the observed experimental values was taken. The developed method has been tested on a series of test problems. The uniqueness of the solution of optimization problem was confirmed by 'descending' from a set of different initial values. Temperature fields within billet of a quartz optical fiber heated by a uniformly moving gas burner were examined. To solve a non-stationary heat conduction problem, finite elements method has been used while the optimization problem has been solved by the Golden section method.


We show that the equivalence between import and export taxes --first demonstrated by A. P. Lerner— does not imply that the effects of import and export subsidies are equivalent, nor can an inference be drawn that a trade subsidy is equivalent to a negative trade tax. It has been over fifty years since Abba Lerner (1936) demonstrated that the impact on the volume and on the terms of trade of a given ad valorem tax would be the same whether it is levied on imports or exports. It has generally been assumed that this symmetry (or, more properly, equivalence) extends to import and export subsidies on the ground that such subsidies are merely negative taxes .' The purpose of this note is to question the validity of these two inferences drawn from Lerner's classic analysis, namely (I) that a trade subsidy may be viewed and treated as a negative trade tax with symmetric effects, and (2) that there exists an equivalence between the effects of subsidies on imports and on exports . I. THE ASYMMETRY BETWEEN IMPORT TAXES AND SUBSIDIES In Figure 1, TT represents the production possibility boundary for a small economy whose terms of trade as shown by the line P,v.2 Under free trade and in the absence of transport costs, domestic prices will equal world prices (Pd = Pti,,), with this economy producing the basket P and consuming at C. With pc and pin denoting, respectively, the world prices of the exportable and importable commodities, and ad valorem nonprohibitive tariff tin on imports will induce domestic suppliers to raise their price to the level of the tariff-augmented cost of imports. The domestic commodity price ratio is then 1'1 =pc/[(1 + tin)Pm] = Pw/(l + t m) < P ,,, • With domestic consumers and producers facing Pa, production shifts to pl and consumption to Cl in Figure 1. The conviction that an import subsidy will lower the selling price for firms in Chacholiades (1978, pp. 458-61) points out that whereas the government may spend the tax revenue itself or distribute it to the private sector, it must be assumed that the government will raise the revenue needed to finance a subsidy through an income tax on private consumers. 2 For a country possessing monopoly or monopsony power in trade , it is necessary to analyse the effects of a tax or subsidy on the supply of exports and the demand for imports at the initial terms of trade in order to explain its effect on the equilibrium terms of trade. The relevance of our model is thus not diminished by the small country assumption adopted here.


Objective: To assess the effect on weight and blood pressure of an educational intervention in obese hypertensive patients. Material and Methods: A before-after study was conducted to evaluate the effect of a 12-month educational intervention on weight and blood pressure in obese hypertensive patients. The individualized educational programme consisted of: nutrition information, motivation test, individualized portion-controlled diet and reinforcement of information once a month with measurement of weight, waist circumference (WC) and BMI. Measurements of BMI (kg/m2), WC (cms), systolic blood pressure (SBP), diastolic blood pressure (DBP) and mean arterial pressure (MAP) were performed at the beginning of the study, one year later (when the educational intervention ended) and two years later. Results: 61 patients were studied (32 men, 29 women), aged 59.84 ± 14.59. BMI decreased in 56 patients (91.8%) and WC in 54 patients (88.5%). The evolution of BMI and WC was: BMI0 33.68 ± 3.56, BMI1 31.65 ± 4.29, BMI2 31.27 ± 3.94, WC0 107.36 ± 10.65, WC1 104.04 ± 10.94, WC2 102.75 ± 10.36. There were differences statistically significant among BMI0 and BMI1 (average reduction 2.03, IC95% 1.46, 2.59, p < 0.05). BMI1 and BMI2 were similar. The average reduction of WC was 3.31 (IC95% 1.94, 4.68), p < 0.05, at one year and 4.61 (IC95% 3.06, 6.17), p < 0.05, at two years. The evolution of SBP, DBP and MAP was: SBP0 138.33 ± 15.30, SBP1 136.12 ± 16.26, SBP2 125.76 ± 15.30, DBP0 83.77 ± 8.37, DBP1 82.29 ± 9.45, DBP2 75.69 ± 7.42, MAP0 102.71 ± 10.08, MAP1 101.14 ± 11.16, MAP2 92.5 ± 11.11. The reduction in blood pressure at one year is not statistically significant, but it reaches statistical significance at two years: average reduction in SBP 12.89 mmHg (IC95% 8.63–17.10) p < 0.05, in DBP 8.30 (IC95% 5.88–10.72) p < 0.05 and in MAP 10.45 (IC95% 7.24–13.67) p < 0.05. Conclusion: An individualized educational intervention in obese hypertensive patients lowers BMI, WC and blood pressure among studied individuals. Waist circumference continues its reduction after concluding the intervention.


Polychlorinated Biphenyls indicator (ΣPCBi) from sediment cores, bed and flood deposits, suspended particulate matters and dredged sediments in the major French rivers (source–estuary transects; 1945–2018) are compared with socio-hydrological drivers. ΣPCBi concentrations increased from 1945 to the 1990s, due to urban and industrial emissions. They gradually decreased with the implementation of regulation. Specific ΣPCBi flux highlighted the amount of heavily polluted sediments transported by French Rivers towards European Seas over 20 40 years. Abstract Environmental pollution by Polychlorinated Biphenyls (PCBs) is a key concern about river quality because of their low degradation rates leading to their accumulation in sediments and living organisms. An original interdisciplinary work was conducted along the four main French rivers (Seine, Rhône, Loire and Garonne Rivers), which flow into 25 major European seas. We completed a dataset based on sediment analyses provided by monitoring agencies, port authorities and research teams on different solid matrices (sediment cores, bed and flood sediments, suspended particulate matters, and dredged sediments). This dataset (n=1416) focused on the seven indicator PCB and their sum (ΣPCBi) from 1945 to 2018. Special effort was put on the quality control to provide robust spatio-temporal information. Taking into account hydrological and human drivers, we outlined two main pollution trends: (1) from 30 1945 to 1975, a quick increase of ΣPCBi (up to 4 mg kg -1 dry weight, dw) and a sharp decrease in the 1980s on the Seine and Loire Rivers; (2) increasing but moderate ΣPCBi levels (50 to 150 µg kg -1 dw) followed by a decline after the 1990s on the Rhône and Garonne Rivers. In addition to these patterns, PCB emissions from urban and industrial areas or accidental events were significant on each river. Finally, when calculating specific flux, the Rhône River exhibited the uppermost ΣPCBi load (up to 12 µg m -2 year -1 in 1977 – 1987), at least 25 % higher than 35 those of the Seine and Loire Rivers, while the Garonne River showed a very low flux. In Western Europe, we confirmed that the Rhône, Seine and Loire Rivers contribute significantly to the PCB contamination of the seas, while French specific ΣPCBi fluxes are two orders of magnitude lower than those found in American or Asian Rivers. The dataset is available at https://doi.pangaea.de/10.1594/PANGAEA.904277 (Dendievel et al., 2019).


Summary Focal mechanisms from microseismic events contain an abundance of information. Moment tensor inversion can lead to a richer understanding of the failure mechanisms and stresses at work at the event source. This information cannot be ascertained from event hypocenter locations alone. Often events recorded during hydraulic fracturing are associated with double-couple (DC) source mechanisms. Hydraulic injection has been associated with non-shear source mechanisms, hence constraining the source mechanism to a shear solution is not appropriate. Data from passive surface monitoring in the Horn River Basin are used to explore moment tensor decompositions. We show that events relating to hydraulic fractures contain significant compensated linear vector dipole (CLVD) components of failure and exhibit b-values of approximately 2. This event population is in contrast to fault reactivation events, which are highly double-couple and have a b-value of approximately 1. This work is part of an ongoing study to integrate geophysical, geological and engineering information.


Discusses some general algorithmic problems encountered when solving linear systems in electromagnetism, such as, e.g. the well‐known difficulties linked with the curl‐curl operator in discrete form. The problem is examined as part of a larger one: solving "mixed" (or as we prefer to say, "constrained") linear systems, with Lagrange multipliers, for which available strategies are reviewed. It is shown that dealing with the mixed system directly, without first getting rid of multipliers, can be a viable proposition.


Planetary exploration has provided a torrent of discoveries and a recognition that planets are not inert objects. This expanded view has led to the notion of comparative planetology, in which the differences and similarities among planetary objects are assessed. Solar system exploration is undergoing a change from an era of reconnaissance to one of intensive exploration and focused study. Analyses of planetary surfaces are playing a key role in this transition, especially as attention is focused on such exploration goals as returned samples from Mars. To assess how the science of planetary geology can best contribute to the goals of solar system exploration, a workshop was held at Arizona State University in January 1987. The participants discussed previous accomplishments of the planetary geology program, assessed the current studies in planetary geology, and considered the requirements to meet near-term and long-term exploration goals.


Estimators of the predictive validity of a multifactorial test are considered. These estimators take into account the selectivity of the sample of those who have observations on the criterion measure. It is pointed out that the selectivity problem can be viewed as a missing data situation. The relationships between the classic Pearson-Lawley adjustment, regression based on factor scores, and maximum-likelihood estimation under ignorable missingness are described. The estimators are compared in a study of artificial population data.


This manuscript presents a dynamic path finding and coordination method for scheduling multiple automated guided forklifts (AGFs) within a given layout of path segments. Unlike small-size automated guided vehicles (AGVs), AGFs are usually of larger size and run in denser path networks, which makes existing time window based methods using path segment occupancy model inapplicable. The path segment conflict model is introduced to resolve this issue. To fulfill the requirement of executing real-time mission flow effectively and free of dead-lock, a complete discrete-edge formed time window based scheduling system with the path segment conflict model is then developed to find feasible paths for the AGFs and coordinate them in real-time. Periodic dynamic replanning of the time window sequences of selective AGFs is also introduced to reduce the negative effects of kinematic uncertainty and communication latency. Simulation tests and real-world deployment results are represented to validate the feasibility and real time performance of the proposed method.


We determine the class of damped modes ỹ which are related to the common free damping modes y by supersymmetry. They are obtained by employing the factorization of Newton's differential equation of motion for the free damped oscillator by means of the general solution of the corresponding Riccati equation together with Witten's method of constructing the supersymmetric partner operator. This procedure introduces one-parameter families of (transient) modes for each of the three types of free damping, corresponding to a particular type of anti-restoring acceleration (adding up to the usual Hooke restoring acceleration) of the form a(t) = 2γ 2 (γt+1) ỹ, where γ is the family parameter that has been chosen as the inverse of the Riccati integration constant. In supersymmetric terms, they represent all those damping modes having the same free damping partner mode. PACS number(s): 11.30.Pb, 43.40At e-mail: email@example.com e-mail: email@example.com 1 The damped oscillator (DO) is a cornerstone of physics and a primary textbook example in classical mechanics. Schemes of analogies allow its extension to many areas of physics where the same basic concepts occur with merely a change in the meaning of the symbols. Apparently, there might hardly be anything new to say about such an obvious case. However, in the following we would like to exhibit a new and nice feature of damping resulting from the mathematical procedure of factorization of its differential equation. In the past, the factorization of the DO differential equation (Newton's law) has been tackled by a few authors [1] but not in the framework that will be presented herein. Namely, recalling that such factorizations are common tools in Witten's supersymmetric quantum mechanics [2] and imply particular solutions of Riccati equations known as superpotentials, we would like to explore here the factoring of the DO equation by means of the general solution of the Riccati equation, a procedure which has been first used in physics by Mielnik [3] for the quantum harmonic oscillator. In other words, we shall exploit the non-uniqueness of the factorization of second-order differential operators, on the example of the classical damped oscillator. We write the ordinary DO Newton's law in the form Ny ≡ ( d2 dt2 + 2β d dt + β ) y = (β − ω 0)y = αy , (1) i.e., we already added a β2y term in both sides in order to perform the factoring. The coefficient 2β is the friction constant per unit mass and ω0 is the natural frequency of the oscillator. The factorization ( d dt + β )( d dt + β ) y = αy (2) follows, and previous authors [1] discussed the classical cases of underdamping (α2 < 0), critical damping (α2 = 0), and overdamping (α2 > 0) in terms of the first order differential equation Ly ≡ ( d dt + β )

Organic materials are important resources for the improvement of soil physical and chemical properties. This study was carried out to examine the impact of tillage and organic matter on some soil structural indices. The study was designed in a split-plot Randomized Complete Block with four replications. Hoe tillage and no-tillage were assigned to the main plot, whilst the subplot comprised cowpea residue, cattle manure, maize residues, elephant grass and control (no organic residue applied). The soil physical parameters measured were bulk density, total porosity, volumetric water content and aggregate stability. Bulk density was lower in the 2013 minor season than in the 2014 major season for all the treatments (1.34 Mg m-3–1.51 Mg m-3). Porosity ranged from 42.98–49.28% in the second season (2013 minor season). The cattle manure treated plots produced the highest volumetric water content of 20.25% and the control gave the lowest value of 16.20% at the end of the last growing season (2014 major season). The highest aggregate stability (74.91%) was recorded on cattle manure plots whilst the control gave the lowest value (71.11%). Crop residues were identified to be good source of organic material for the improvement of soil physical properties.


An experiment was conducted at H.C. & R.I., T.N.A.U., Coimbatore to find out the effect of different chemicals and growth regulators in combination with Thiabendazole (Fungicide) on post-harvest quality and shelf life of plantain cv. Nendran (French Plantain Musa AAB). Various concentration of, GA 3, BA, CaCl 2 and hot water treatment either alone or in combination with Thiabendazole was applied to fruits after harvest to study their impact on post-harvest quality and shelf life. Exogenous application of chemicals, growth regulators in combination with Thiabendazole significantly decreased post-harvest disease incidence leading to increase in post- harvest fruit quality and shelf life. Among the treatments, post harvest dipping of fruits in 150 ppm GA 3 + 200 ppm Thiabendazole significantly increased firmness (3.70 kg/cm 2 ) and titrable acidity (0.09%). While the parameters like PLW (13.53%), TSS (25.45 o B), total sugars (18.88%), reducing sugars (17.11%) and percent disease incidence (5.55) was observed minimum in the same treatment after 12 th day of storage. The shelf life of fruits treated with 150 ppm GA 3 + 200 ppm Thiabendazole could be extended successfully for about 18 days of storage.


Abstract : The object of this study was to determine the levels of toxicity of the liquids and solids of the Waste Lakes F and F-1. This study was requested following evaluation of reports received that Mallard Ducks died after alighting on Lakes F and F-1 and that rabbits had been found dead along their banks. The study found that the solids of Lake F only moderately toxic, but the solids of Lake F-1 are very toxic to the species tested. Based on these tests, Lake F-1 material would present a hazard to wildlife at least 10 times greater than that of Lake F material.


Forensic DNA analysis typically proceeds by first determining whether alleles1 found in DNA apparently left by the perpetrator of a crime at a crime scene2 (the "evidence sample") match alleles extracted from a sample of the suspected criminal's blood (the "suspect sample"). If alleles drawn from the two sources match, the next step is to provide information about the probative value of the match by estimating the probability that alleles extracted from the blood of some random individual would have matched the alleles in the evidence sample. This probability estimate is typically made by estimating the frequency with which specific alleles are found in some population and combining these frequencies according to the product rule.3 Obviously, a match


The main objective of this study was to determine the impact of increased demand for peregrine falcons via breeding (mainly Polish, Czech, German and Slovak) on the genetic structure of the birds. In the analysis, 374 specimens from six countries were sampled in 2008–2019 (omitting 2009), and all the birds analyzed were released into the wild as part of the Polish reintroduction program. The assessment of genetic variation was based on a well-known panel of 10 microsatellite markers described for the species. We calculated a fixation index for the samples from each year, and based on this, we determined the level of inbreeding. We also performed an analysis using the Bayesian cluster method, assuming that 1–19 hypothetical populations would define the division that best fit the samples. The most probable division was into two groups; in the first group, the samples from individuals delivered in 2013 were most often segregated; moreover, in this year, a jump in inbreeding, expressed by the fixation index, was observed.


ABSTRACT Comparison among the structurally similar analogous or isomeric novel homologous series of presently investigation is discussed with a view to understand the effect and relation between molecular structure in respect of molecular size, geometrical shape, molecular polarity and polarizability etc as emerged from changing molecular rigidity and flexibility which is played by terminal or central bridge to inducing liquid crystal property and the specific degree of mesomorphism of a substance. Novel series of study consists of three phenyl rings, two central bridges ‒COO‒, ‒CH˭CH‒COO‒, ‒COO‒CH2‒, ‒CH˭CH‒COO‒CH2‒ with common left n-alkoxy (‒O‒CnH2n + 1) left terminal group which vary from homologue to homologue in the same series and varying tail end group –Cl and –Br. Novel members of series were selectively characterized and confirmed by elemental analysis, IR spectra, H1NMR spectra, mass spectra, POM, textures of smectic or/and nematic phase by miscibility method etc. Totally 66 novel compounds were synthesized and 55 compounds were to be found liquid crystal (LC) in nature with different degree of mesomorphism depending upon changing molecular structure in respect of their tailed flexible end groups or central bridges.


abstract:Mobility scholars tend to portray people on the move as using various strategies to outmaneuver the governments or companies aiming to control them. This article shows that when some travelers prioritized convenience on their daily trips, their shortcuts and hacks led to unexpected run-ins with dangerous machinery. In early 1900s rural America, pedestrians and motorists used railroad tracks carelessly and intentionally—a chaotic combination epitomizing the hustle and bustle of everyday life. When those travelers died in train collisions, their survivors sued railroad companies, thus pitting the victims' risky behavior against companies' powerful legal defense. Two trials from Pennsylvania in 1915 and 1932 contrast the adversaries' sense of railroad space, presenting the landscape's impact on everyday movements that people take for granted. The case studies will push historians to pay more attention to the gray zone of popular, yet illegal, behaviors that bring people into contact with technology.

In this paper, by using hidden markov model and svd coefficient. we proposed image based fraud prevention. Based on priority here we are taking seven state HMM. As another novel point, we used a small number of quantized Singular Values Decomposition (SVD) coefficients as features describing blocks of face images. Fraud prevention describes measures to avoid frauds that occur in the first place. Instead of outlier we are taking image as an input that input is human face. A wide variety of techniques have been proposed for feature extraction by using HMM and SVD coefficient. Based on priority here we are taking seven states HMM. When the card is inserted to ATM then it asks the pin number and captures the image. The image features are extracted then compared the image with the image stored in the training data base. If the image is matched then the transaction will proceed. If the image is not matched with the images in database then the transaction will not proceed. Image may be finger print or face. So by using image we can prevent the frauds. Keywords— Face Recognition, Hidden Markov Models, Singular Value Decomposition.

Abstract : Results of an investigation of concepts for modeling jet plume effects on missile aerodynamics tend to confirm the concepts proposed by Korst. Comparisons were made of afterbody pressure distributions influenced by plumes of the same shape but with different plume Mach numbers and with a solid plume. These comparisons indicate that increasing effect becoming more pronounced with increasing freestream Mach number. The solid plume has the greatest effect on afterbody pressures with the effect increasing considerably at Mach numbers of 1.25 and higher. (Author)


We suggest the experimental study of $p\bar p \to W^-- {}_\gamma X$ as a test to distinguish between the fractionally charged quark (FCQ) model and the integrally charged quark (ICQ) model. We find that the strong dip in cross section at cos θ=−1/3 (θ being the angle between the W− and the proton direction in the W−γ c.m. frame) in the FCQ model is washed away in the ICQ model. Thus the presence or absence of this dip provides a clean test to distinguish these two models above color threshold.


The purpose of this paper is a examination of the correlation between a local spinning company and Zaibatsu (financial group) during the period of capitalism establishment by utilizing the data about Kyushu Spinning Company and Mitsui.Kyushu Spinning Company was established by consolidation of three companies, or Miike, Kurume and Kumamoto spinning company, in 1899. This company had about 50, 000 spindles and was a big company at that time as a local one. But its business results was aggravated by an effect of the post Sino-Japanese war depression. Futhermore, the speculation that Matazo Moriyama, the manager of Osaka branch of Kyushu Spinning Company, put into operation to cover above aggravation resulted into failure. Then, managers of this company tried to reform the business by calling up un-paid capital, but this plan did not be realized because a capacity in raising capital of local stockholders was very limited.Consequently, reformation of this company was left to Mitsui accompanied by stockholders' loss from capital reduction. Mitsui obtained the managerial rights of this company, on the other hand it improved a financial position of this company with its large ability in raising capital. And it made efforts to increase the profit through a reduction in interest payment and a utilization of sales ability that Mitsui-bussan (trading company) had.Thus, supported by the recovery of business conditions, Mitsui accomplished managerial reformation of Kyushu Spinning Company with its synthetic ability as a Zaibatsu. And then, Kyushu Spinning Company was absorbed by Kanegafuchi Spinning Company, a company that was a member of the Mitsui Zaibatsu, in 1902.


【Purpose : The purpose of this study was to determine a conversion coefficient for Hounsfield Units(HU) to material density ( $g\;cm^{-3}$ ) obtained from cone-beam computed tomography ( $CBMercuRay^{TM}$ ) data and to measure the hard tissue density based on the Hounsfield scale on dental head phantom. Materials and Methods : CT Scanner Phantom (AAPM) equipped with CT Number Insert consists of five cylindrical pins of materials with different densities and teflon ring was scanned by using the $CBMercuRay^{TM}$ (Hitachi, Tokyo, Japan) volume scanner. The raw data were converted into DICOM format and the HU of different areas of CT number insert measured by using $CBWorks^{TM}$ . Linear regression analysis and Student t-test were performed statistically. Results : There was no significant difference (P > 0.54) between real densities and measured densities. A linear regression was performed using the density, $\rho$ ( $g\;cm^{-3}$ ), as the dependent variable in terms of the HU (H). The regression equation obtained was $\rho=0.00072H-0.01588$ with an $R^2$ value of 0.9968. Density values based on the Hounsfield scale was $1697.1{\pm}24.9\;HU$ in cortical bone, $526.5{\pm}44.4\;HU$ in trabecular bone, $2639.1{\pm}48.7\;HU$ in enamel, $1246.1{\pm}39.4\;HU$ in dentin of dental head phantom. Conclusion : CBCT provides an effective option for determination of material density expressed as Hounsfield Units.】

Abstract An experimental study is reported in which a comparison was made between the attainment gains of Guyanan secondary school children following different learning regimes. The use of systematically designed learning materials produces significant gains in learning when compared with conventional teaching. These differences are also seen when the attainment of high‐order cognitive skills is compared to the attainment of low‐order cognitive skills. The attainment of high‐order cognitive skills is very poor in conventional classroom situations. The significance of these results is discussed in terms of curriculum design and teacher performance in the classroom.


The British Columbia Frustrated Contracts Act is different to the English Law Reform Act 1943. In 1948, the Conference of Commissioners on Uniformity of Legislation in Canada adopted the English Frustrated Contracts Act 1943, with some minor modifications, as a model Act. The 1948 Uniform Frustrated Contracts Act was subsequently adopted in every common law Canadian state except British Columbia, Nova Scotia and Saskatchewan. Section 5 of the British Columbia Act is probably the most important part of the Act, as it provides for the adjustment of the rights and liabilities. The method of restitution contemplated by section 5(2), with the wide definition of a 'benefit' in section 5(1), is fairly straightforward. An example of such a straightforward application of the Act can be seen in KBK No. 138 Ventures Ltd. v. Canada Safeway Ltd. Section 5(4) of the British Columbia Act provides for the apportionment of certain losses incurred. Keywords: British Columbia Frustrated Contracts Act; Canadian state; common law; English Law Reform Act 1943; restitution


Microwave Oven (MWO) and Wireless Local Area Network (WLAN) both operate in the 2.4 GHz Industrial, Scientific and Medical (ISM) Band. Microwave oven does not take care of Wi-Fi channel usage; its operation in the same band of frequency can cause degradation of Wi-Fi network performance. This novel experimental arrangement investigates the performance of the WLAN network under the effect of simultaneous operation of two Microwave ovens, in different physical arrangement scenarios. The experiment consists of two laptops as victims, two microwave ovens as interferers, WLAN Access Point as Transmitter and AirMagnet Hardware/Software setup as Performance Analyser. Different Performance Indicators of WLAN performance are analysed in this investigation. It has been observed that Wi-Fi network performance degradation increases significantly when both microwave ovens are located near the receiver (Laptop) side. The microwave ovens have relatively lesser adverse effects when both are placed near the transmitter (Access point) or at center (between transmitter and receiver).


This chapter analyses the transformative effects of the new pattern of public–private collusion on prevailing conceptions and categories of the public interest. This dynamic development can be seen by following the trail of the group of mobile and multipositioned civil servants or politicians who turned corporate lawyers. As they invent new professional know-how and career paths, they personify, more than any other group, the dynamics of this interstitial space. They collectively act as brokers between the various poles of this field, create points of convergence, and actively disseminate new ways of thinking of the state and its role vis-à-vis markets. The density of this field of public–private intermediation can also be measured by looking at a diverse range of seemingly secondary platforms, including professional colloquia, sector-specific congresses, and other policy-oriented meetings and discussion series that are explicitly aimed at bringing together public and private professionals. These arenas provide participants with opportunities to liberate themselves from their respective institutional or professional loyalties and to profess the virtues of public–private synergies.


Background: Coronary artery anomalies are very rare congenital conditions. Rarely occurring but potentially fatal abnormalities of the coronary vasculature, abnormalities of the coronary arteries can cause significant cardiac events such as myocardial ischemia (S-T Segment elevation MI) and cardiac arrest.
Case Presentation: We are presenting a case of a 60 years old hypertensive female patient who presented with ST-segment elevation in all precordial leads.
Management & Results: On angiography, a giant right coronary artery was seen, and no Left coronary artery origin was not appreciated. Hence, Multidimensional CT angiography was done that showed dilated and ectatic left main coronary artery circulation originating from the pulmonary artery just above the pulmonary valve. The patient was declared a high-risk surgical candidate, was advised medical therapy, including beta blockers, dual antiplatelet, and antihyperlipidemic medications, and was advised to restrict physical activity.
Conclusion: The rare presentation of an aberrant coronary artery is myocardial infarction with ST-segment elevation, and it might be difficult for doctors and cardiologists to determine the true reason without intervention. To optimize the care of these patients, traditional CAA and MDCT must be integrated with the clinical presentation of the patients.


Sequential synthetic culture medium composition for in vitro maturation and fertilization of human oocyte and culture methods by using the same compositions are provided to increase implantation and pregnancy rates by supplying nutrients to human oocyte. The sequential synthetic culture medium composition for in vitro maturation and fertilization of human oocyte comprises the synthetic culture buffer solution(SCB) and synthetic addition solution for maturation(SASM) in a volume ratio of 85:15, wherein the synthetic culture buffer solution(SCB) contains NaCl, KCl, MgSO4 7H2O, CaCl2, Na2HPO4, KH2PO4, KHCO3, NaHCO3, sodium pyruvate, D,L-sodium lactate, D-glucose, SNEaaX(x66.67), SEaaS(x 66.67), L-alanyl-L-glutamine, glycyl-L-glutamine, H2O, D-Ca-pantothenate, choline chloride, folic acid, i-inositol, nicotinamide, pyridoxal HCl, riboflavin, thiamine HCl, penicillin-G, streptomycin-S and phenol red; and synthetic addition solution for maturation(SASM) contains NaCl, KCl, MgSO4 7H2O, CaCl2 2H2O, Na2H2PO4, Na2HPO4, KH2PO4, KHCO3, NaHCO3, sodium pyruvate, D-glucose, Na2EDTA 2H2O, SNEaaS(x 66.67), SEaaS(x 66.67), L-alanyl-L-glutamine, glycyl-L-glutamine H2O, L-taurine, D-Ca-pantothenate, choline chloride, folic acid, i-inositol, nicotinamide, pyridoxal HCl, riboflavin, thiamine HCl, penicillin-G, streptomycin-S, phenol red, albumin, globulin, hyaluronic acid, insulin, transferrin, sodium selenite, epidermal growth factor(EGF), insulin-like growth factor-II(IGF-II), lutenizing hormone(LH) and follicle stimulating hormone(FSH). The method for culturing human oocyte comprises the steps of: preserving equilibrium of the sequential synthetic culture medium composition in an incubator under 5% CO2 and 36.8 deg. C prior to 1 day of oocyte collection; and incubating the unmatured oocyte in the medium composition for 24-48 hours.

ABSTRACT Expression of virulence-related extracellular proteases, gelatinase, and serine protease of Enterococcus faecalis is regulated by a quorum-sensing system encoded by the fsr gene cluster. In this study, a 23.9-kb chromosomal deletion containing the fsr gene cluster region was found to be present in the majority (79%) of gelatinase-negative clinical isolates of E. faecalis from urine.


Open data are playing a vital role in different communities, including governments, businesses, and education. This revolution has had a high impact on the education field. Recently, Linked Data are being adopted for publishing and connecting data on the web by exposing and connecting data which were not previously linked.
In the context of education, applying Linked Data to the growing amount of open data used for learning is potentially highly beneficial. This paper proposes a system that tackles the challenges of data acquisition and integration from distributed web data sources into one linked dataset. The application domain of this work is medical education, and the focus is on integrating educational
content in the form of articles published in online educational libraries and Web 2.0 content that can be used for education. The process of integrating a collection of heterogeneous resources is to create links that connect the resources collected from distributed web data sources based on their semantics. The proposed system harvests metadata from distributed web sources and enriches it with concepts from
biomedical ontologies, such as SNOMED CT, that enable its linking. The final result of building this system is a linked dataset of more than 10,000 resources collected from PubMed Library, YouTube channels, and Blogging platforms. The final linked dataset is evaluated by developing information retrieval methods that exploit the SNOMED CT hierarchical relations for accessing and querying the dataset. Ontology-based browsing method has been developed for exploring the
dataset, and the browsing results have been clustered to evaluate its linkages. Furthermore, ontology-based query searching method has been developed and tested to enhance the discoverability of the data. The results were promising and had shown that using SNOMED CT for integrating distributed resources on the web is beneficial.


Acute high -intensity resistance exercise increases arterial stiffness, which is one potential mechanism of the increased arterial stiffness resulting from resistance exercise training. Estrogen concentrations in women may also influence arterial stiffness. Therefore, changes in arterial stiffness after high-intensity resistance exercise might differ according to the menstrual cycle. PURPOSE: The purpose of this study was to determine the effects of menstrual cycle phase on arterial stiffness after high-intensity resistance exercise. METHODS: Nine eumenorrheic females participated in this study (age 21.3 ± 0.8 years). None of the participants were taking oral contraceptives. Menstrual cycles were categorized according to serum estrogen and progesterone concentrations. Maximal muscle strength was assessed using one repetition maximum (1RM) strength tests 1 week before starting this study. The participants performed five sets of five repetitions using 80% of the 1RM bench press and five sets of ten repetitions using 70% of the 1RM biceps curl with an inter-set rest periods of 2 min at each of the menstrual, ovulatory, and luteal phases. Brachial-ankle pulse wave velocity (baPWV; an index of arterial stiffness), blood pressure, and heart rate were measured before (baseline) and at 30 and 60 min after completing the resistance exercise. RESULTS: Serum estrogen concentrations were significantly higher at the ovulatory and luteal phases than at the menstrual phase (ovulatory and luteal phases vs. menstrual phase; 192 ± 58, 170 ± 32 vs. 40 ± 7 pg/ml, P<0.05). The baPWV at the menstrual phase was significantly increased from baseline at 30 min (baseline vs. after 30 min; 952 ± 16 vs. 1061 ± 29 cm/sec, P<0.05) after the resistance exercise and persisted for 60 min (baseline vs. after 60 min; 952 ± 16 vs. 1044 ± 23 cm/sec, P<0.05), whereas the ovulatory and luteal phases did not significantly differ before and after the resistance exercise. Blood pressure and heart rate did not significantly differ before and after highintensity resistance exercise during any phase. CONCLUSION: These results suggest that arterial stiffness induced by high-intensity resistance exercise changes according to phases of the menstrual cycle.


In this work, we have described the use of K2CO3/Propylene Glycol (PG) deep eutectic solvent (DES) as green and efficient alternative to volatile organic solvents for the formation of a very important reaction intermediate i.e., nitroaldols via Henry Reaction. Interestingly, the DES acted both as the solvent as well as the catalyst without the assistance of external base, solvent and additive. Further, the obtained nitroaldol product was utilized for nitroolefin synthesis.


We are developing a superfluid [sup 4]He analog of the rf SQUID. A thin partition with a micrometric orifice is placed inside a toroidal container filled with liquid helium; ac and dc superflows through the orifice are induced by rotating the whole torus, which is the inertial member of a torsional oscillator. The torus oscillation amplitude vs drive curve shows a small but reproducible staircase pattern, which is detectable between 1.4 and 2.05 K, but is not modulated by a superimposed steady rotation. We discuss this behavior in terms of the occurrence of multiple phase slips.


Neutral beam injector (NBI) heating of electrons has been observed in the Madison Symmetric Torus (MST). This heating is consistent with a simple 1D model which includes the effect of fast ion diffusion, neutralizationlosses and classical collisional processes. This heating was achieved with a 1 MW NBI (25 kV, 40 A). Auxiliary heating of MST has been observed with Thomson scattering to be 100±50 eV in the core of 200 kA PPCD (pulsed poloidal current drive) plasmas. Auxiliary heating has been measured in other PPCD plasmas, but not in standard confinement plasmas. This data represents the first confirmed auxiliary heating of a reversed-field pinch (RFP) plasma. Enhanced confinement plasmas are conducive to auxiliary heating because of the improved thermal confinement. Ion temperatures were measured with a Rutherford scattering device, but investigation determined that NBI fast ions are able to get into the Rutherford analyzer at a large enough rate to add a significant non-Gaussian component to the observed data. Controlling for this additional neutral hydrogen signal eliminates false detection of auxiliary heating with NBI in standard MST plasmas. Further analysis suggests that fast ions from magnetic reconnection events could also be polluting MST sawtooth Rutherford data. A 1-D model of NBI heating in MST was developed. This model takes measured and calculated inputs such as plasma temperature, plasma density and ohmic heating profiles and solves for heat diffusion coefficient profiles. The assumption underlying this calculation, that the heat diffusion coefficients do not change when the NBI is firing, is justified because the NBI does not significantly suppress mid-radius magnetic fluctuations. The base 1-D model includes fast ion deposition, fast ion diffusion and fast ion slowing down. Fast ions are lost to the plasma via thermalization and contact with the MST wall. Neutral losses

To the Editor.

The article by Southall et al ( Pediatrics. 1997;100:735–760) confirms the report of Rosen et al ( Pediatrics. 1983;71:715–720). However, I have serious reservations about the design of this study.

It appears that the 39 cases selected for covert video surveillance (CVS) came from two sources, two cases from the "district" and 37 from "outside the district," referred by physicians who knew the aims of the study. They were previously alerted to look for families who fit a particular profile. CVS was used in the 39 cases because "members of a strategy planning group strongly suspected abuse." What selection criteria were used by the referring physicians and the strategy group so that CVS documented abuse in 33 of 39 cases?

The 46 "controls" required cardiopulmonary resuscitation for an apparent life-threatening event and a "natural cause" (respiratory disorders and epilepsy) was identified. Were infants with cardiac arrhythmias referred to other centers? These families were not referred because of the same suspicions of fatal abuse. If the basis for referral of the CVS-monitored group included both the psychosocial profile and/or the previous loss of an infant to sudden infant death syndrome (SIDS), and these were not selection criteria for …


habitat the mast granule substance is passed into the lumen of capillaries. Webb (1931) made counts of mast cells along unit segments of arterioles in subcutaneous tissue of normal rats and compared them with counts from rats given intraperitoneal injections of egg albumen and carbon and found in the latter animals a marked increase in the number of mast cells. In the hypophysis, according to Gray (ig35), mast cells or fragments thereof can never be observed in the lumen of capillaries. The disposition of mast cells into densely packed clusters is, likewise, a frequent phenomenon and is especially apparent in the mesentery, omentum, tongue, digestive tract and intermuscular connective tissue. In the lower vertebrates group formation of mast cells is much more marked and frequent than in mammals (Figs. 80, 81). In the air bladder of carp the cells parallel muscle fibers in chain-like sequence (Fig. 85) while in the mesentery, aggregates often comprise over zoo cells (Fig. 88). Bolton (1933) states that in the gut of salmonoids the mast cells are densely grouped on either side of the stratum compactum (collagenous material) of the tunica propria. Since grouping of mast cells occurs in all vertebrates, the phenomenon cannot be accidental. Emigration or diapedesis (Heller, Turk, Brack) can hardly account for the marked regularity in cell disposition. Hence the causative factors of grouping are amebism and mitosis, and probably amitosis as suggested by Lehner. Under pathologic conditions grouping of mast cells is still more frequent. Here grouping may perhaps occur as a sequence to positive chemotaxis, as exemplified in the aggregates found in the immediate neighborhood between normal and carcinomatous tissue (Fromme, 1906; Higuchi, 1930) and in cutaneous tumors (Sabrazks and Lafon, 1908; Cornil and Michon, 1924), especially those produced with tar (Bierich, 1922; Fabris, 1927).


Kigraine is a typical "women's disease", not only because of its predominance in the female sex, but also because the changes in sexual hormones associated with events in the reproductive life have a direct influence on its course. This however does not seem to concern to the same extent migraine with aura and migraine without aura: in fact the latter is affected much more by the modifications in the hormonal milieu. We therefore thought it would be useful to investigate the relationship between events in the reproductive life and headache in a large population of women suffering exclusively from migraine without aura. Patients and methods A retrospective study was conducted on 1300 women suffering from K referred to the Headache Centres of Pavia and Parma from 1984 to 1989; all the data concerning the reproductive life and the modifications induced by it on the course of headache were drawn from record-charts. Results K had its onset at menarche in 11.4% of cases, during puerperium in 4.5% and at the time of menopause in 4.3%. The 72.1% of patients reported their menstrual cycles to be regular. the 27.9% irregular; in menstrual K (at least 90% of attacks during perimenstrual period) these percentages were respectively 90.5% and 9.1~ (p<0.01). Table 1 shows the relationship between migraine attacks and the menses. The course of K during pregnancy is shown in Table 2. Taking the contraceptive pill (N = 324) caused K onset in 8 cases (2.5~), a worsening in 78 (24.1~). no change in 211 (65.1%). an improvement in 25 (7.7~) and the disappearance of headache in 2 (0.6%). With menopause (N = 164) there was disappearance in 2 cases (1.2%). improvement in 22 (13.4~). no change in 77 (47.0%). worsening in 51 (31.1%), onset in 12 (7.3%). In women with surgical menopause (N = 48) in no case K improved (natural

2405 Pre-university period is a stressful moment for Brazilian students, since they are submitted to eliminatory exams to be admitted at public and private universities. According to previous studies this condition generates increase of the number of stress symptoms that can contribute to physical and psychological disorders, such as anxiety, depression, diarrhea, sleep disturbance and muscle tension. Acute exercise decreases behavioral and physiological manifestations of the stress response. Stretching exercise can be used to treat stressed patients since it can produce relief factors. Music is also used as a therapeutic tool to treat some diseases. PURPOSE: to verify the acute effects of stretching exercise and music listening on the number of stress symptoms of pre-university Brazilian students. METHODS: Two hundred and fifty students of preparatory courses for university admission exams were separated into four experimental groups: control (C), stretching exercise without music (S), music listening (M), and stretching exercise with music (SM). The participants of S and SM groups performed active stretching exercise sessions. The participants of M and SM groups listened the same "New Age" music sequence. The total time of each

Airborne transmission of respiratory viruses consists of three sequential steps: (1) release of respiratory fluids in the form of droplets from the nose and mouth of an infected person, (2) transport of the droplets through air, and (3) entry of the droplets into the nose and mouth of an uninfected individual. Talking, coughing, and sneezing emit droplets across a spectrum of sizes. The water in exhaled droplets begins to evaporate in air and, as a result, the droplets are reduced in size shortly after being emitted. Face masks are effective for capturing droplets just released from the nose and mouth. Studies indicate that more than 50% of community transmission of SARS-CoV-2 is from asymptomatic and pre-symptomatic cases. Use of face masks by the public can effectively reduce the chance of infected individuals unknowingly spreading the virus. In addition to being an effective device for source control, face masks can protect the wearers from inhaling virus-laden droplets. Cloth masks and disposable masks provide reasonable protection for the public, while surgical masks and N95 respirators give higher levels of protection as needed in healthcare settings. Made with varied materials, these masks have different structural characteristics. The collection efficiency of a face mask depends on droplet size, face velocity, and the structural characteristics of the mask. For a given mask, capturing droplets is more effective during exhalation than during inhalation. Pressure drop across the mask should be taken into consideration when selecting a face mask. The best face mask is the one that gives the highest collection efficiency with the least pressure drop. For an effective protection, a mask should fit the face properly. While face masks have proven adequate in reducing airborne transmission of SARS-CoV-2 infections, continuous improvement is needed to better prepare for future respiratory viral threats. © The Author(s).

A duel-concentric-core photonic crystal fibers (DCC-PCF) have been proposed and demonstrated with pure silica as substrate and air holes as cladding materials. The finite element method with perfectly matched absorbing layers boundary condition is used to investigate the guiding properties. The chromatic dispersion and propagation characteristics of DCC-PCF have been simulated systemically. A very high negative chromatic dispersion value-106040 ps/nm/km and nearly zero 0.373 dB/km confinement loss can be achieved at 1.55 μm wavelength by using the modest number of design parameters with very simple core-cladding design. Moreover, the fundamental mode and second mode also described elaborately.


The dynamic effects of breakup Channel on for 8B+58Ni, 9Be+64Zn, and 12C+208Pb systems in elastic scattering reactions have been studied by calculating two quantities, which are the cross-section of the scattering and the distribution of the scattering barrier as functions of the angle of the center of the block and the energy of the center of the mass of some selected systems whose nuclei are Weakly Bound. The calculations are based on continuum discretized coupled-channel (CDCC) theory using code (CC) full quantum mechanics. The interpretation of the experimental findings was evaluated in the context of the optical model using the Woods-Saxon potential. both real and imaginary. In the context of the optical model of the real and imaginary parts, the interpretation of experimental results was analyzed using Woods-Saxon potential. The uncoupling and coupling channels (CC) have been calculated with the energy center Ec.m. to achieve the maximum consistency with experimental data for the systems being studied. The effect of breakup channel is giving a good description of results to be in agreement with experimental data.

Background Therapeutic gene delivery to the central nervous system (CNS) remains a challenge in Huntington's disease research. The blood brain barrier restricts the delivery of therapeutic agents to various cell types in the CNS known to be involved in disease progression. Recombinant adeno-associated viral vectors (rAAVs) are frequently used for in vivo gene delivery in neurodegenerative research but can have poor or limited tropism in the CNS when delivered systemically. When injected directly into the CNS, AAVs are efficient at transducing a variety of cell types though with limited spread. Conversely, when naturally occurring AAVs are injected systematically they lead to widespread transgene expression but with low transduction efficiency. Aims The aim of this experiment was to utilise a novel AAV variant, ssAAV-PHP.B:CAG-GFP, to investigate and compare its transduction efficiency in brains of wild type (WT) and R6/2 mice. Methods Four week old WT and R6/2 mice were intravenously injected through the tail vein with 5 × 109 vg/g with ssAAV-CAG-NLS-GFP packaged into AAV-PHP.B. Three weeks later, the mice were perfused and the brains processed for immunohistochemistry. GFP expression was assessed using images captured by a laser scanning confocal microscope. Results We show that systemic delivery of this AAV variant results in widespread and efficient GFP expression in different cell types throughout the CNS in both WT and R6/2 mice. Currently, we are assessing the impact of age and disease stage upon transduction efficiency. Conclusion Our results demonstrate the potential for use of this AAV vector as an approach to knock-down or deliver genes of interest to the CNS. Funding CHDI Foundation

ABINIT program package based on Density Functional Theory (DFT) within the Generalized Gradient Approximation (GGA) and plane wave basis set are used to calculate the magnetic properties of Mn doped NiO. It was found that the magnetic properties of Mn doped NiO were changed from anti-ferromagnetic (pure NiO) to ferromagnetism. Increasing the concentrations of Mn, the magnetization of Mn doped NiO were increased (Ni31MnO32 = 66.69 µB, Ni30Mn2O32 = 69.59 µB and Ni29Mn3O32 = 72.42 µB).


This article describes the SYSAL system which presents a unique approach to the subject of vehicle location within the framework of a Fleet Management Sytem. SYSAL integrates three technologies: differential odometer, map matching and differential corrected global positioning satellite systems. Two modes of operation, for fixed route vehicles and random-route vehicles, are described. The distance covered is derived from averaging measurements from two odometer sensors mounted on the two front wheels and changes in heading from the difference between them. Storage of a route map for fixed route vehicles is described. The three major components of the system, the mobile equipment, command centre and communications are briefly outlined. The advantages of SYSAL compared to other systems are considered. For the covering abstract see IRRD 866027.

Three isotopic species of a weakly bound T‐shaped π complex formed between acetylene and HCl have been observed through the assignment of their rotational spectra by the use of a pulsed, Fourier‐transform spectrometer with a high pressure gas being pulsed into an evacuated Fabry–Perot cavity. The spectra clearly show the complex to be a nearly prolate asymmetric top (κ = −0.9898) with the HCl on the a‐inertial axis and perpendicular to acetylene and with the hydrogen atom pointing towards the middle of the acetylene triple bond. The chlorine is situated, on average, 3.699 A from the edge of the acetylene molecule. The following molecular constants have been obtained for the C2H2, H35Cl isotopic species: The rotational constants are A = 36 084(838), B = 2481.065(6), and C = 2308.602(6) MHz; the nuclear quadrupole coupling constants are χaa = −54.342(4), χbb = 26.862(5), and χcc = 27.480(9) MHz, and the rotational centrifugal distortion constants are DJ = 7.9(4) and DJK = 497(8) kHz.


We investigate the entanglement between electronic and vibrational degrees of freedom produced by a vibronic coupling in a molecular system described in the Born-Oppenheimer approximation. Entanglement in a pure state of the Hilbert space $\cal{H}$$=$$\cal{H}$$_{el}$$\bigotimes$$\cal{H}$$_{vib}$ is quantified using the von Neumann entropy of the reduced density matrix and the reduced linear entropy. Expressions for these entanglement measures are derived for the $2 \times N_v$ and $3 \times N_v$ cases of the bipartite entanglement, where 2 and 3 are the dimensions of the electronic Hilbert space $\cal{H}$$_{el}$, and $N_v$ is the dimension of $\cal{H}$$_{vib}$. We study the entanglement dynamics for two electronic states coupled by a laser pulse (a $2 \times N_v$ case), taking as an example a coupling between the $a^3\Sigma_{u}^{+} (6s,6s)$ and $1_g(6s,6p_{3/2})$ states of the Cs$_2$ molecule. The reduced linear entropy expression obtained for the $3 \times N_v$ case is used to follow the entanglement evolution in a scheme proposed for the control of the vibronic dynamics in a Cs$_2$ cold molecule, implying the $a^3\Sigma_{u}^{+}(6s,6s)$, $0_g^-(6s,6p_{3/2})$, and $0_g^-(6s,5d)$ electronic states, which are coupled by a non-adiabatic radial coupling and a sequence of chirped laser pulses.


Leader and followers are the two critical and essential aspect of any organization. They play equally important roles in the success of an organization. It is the followers who make a leader. At the same time the followers would lose their strength and unity without a leader, thus making it a reciprocal phenomenon. This relationship cannot be ignored as it directly affects the organizational outcomes. The Leader follower relationships were not duly recognized in the initial phases of behavioral studies related to leadership and its implications. The (leader) manager's job was viewed as getting work done by the employees to achieve the organizational goals. Abstract Every organization aims to grow and excel in their business activity. Human resource being the most critical element to the success of any organization, this paper is an effort to understand authentic leadership and its significance in the reference of building leader-follower relationship which not only affects the organizational goal accomplishment but also play important role in enhancing the overall effectiveness and efficiency of the organization. A leader's contribution in the organization is not only to take and execute decisions or formulate and implement strategies, but also to motivate and influence the team towards goal accomplishment. Whereas on the other hand, the extent to which a leader is seen as being authentic and honest influences the fate of goal achievement. This study is conceptual in nature with the motive to analyze the concept of authentic leadership in reference to leader-follower relationship. Authentic leadership is a positive mode of leadership with high moral standards, ethics, integrity and values. The study also emphasizes on the qualities of a leader which make them authentic and leader's authenticity enhances trust of employees in their leader through relational transparency which further develops strong leader-follower relationship. A new term for authentic leaders has been developed on the bases of their qualities of leading people and also suggested a model of 'authentic leadership and leader-follower relationship'.


Content management systems (CMSs) are critical software platforms for the success of organizational web sites and intranets. Although most current CMS systems allow their extension through the addition of modules/components, such modules are usually relatively static, allowing only the configuration of certain parameters that constrain some aspects of their presentation.This paper presents the architecture of WebComfort, a dynamic component-based CMS platform which allows users to manage and operate complex web applications in a dynamic and integrated fashion. The major technical details of this system are described in this paper, such as modules, toolkits, the data repository access, and the WebComfort API.


A report of the International Labour Organization on undeclared work in Greece refers to failures of formal institutions which contribute to the asymmetry between state and civic morality. The particular asymmetry is explored through the context of tax morale, which is one of the major determinants of the shadow economy. Although several papers have been published on the Greek shadow economy, tax morale in Greece has not been adequately explored. This research aims to investigate the effect of the economic downturn on the factors determining the level of tax morale through primary data from a European Union-funded research project on the Greek shadow economy. The findings provide policy orientations toward transferring activities from the shadow to the official economy, a goal which is part of Europe 2020 strategy.


The problem of sound classification has been studied in depth and has multiple applications related to identity discrimination, enhanced hearing aids, robotics, and music technology. There are two ways in which the problem of sound classification can be approached. The first method is empirical in nature, and requires a database of sounds to learn from through feature extraction. The second method is more top down, by using predefined feature rules to make classification decisions. In this project, we take the developmental approach, and use learning mechanisms to enable a robot to gain meaningful information about its environment through sound. Specifically, we compare two classification algorithms: a k-nearest neighbor characterization of our sound data, and a deep neural net classifier. We outline the tradeoffs between the two methods in computational intensity and accuracy, and report further directions for research.


Abstract This article is concerned with a Leslie–Gower predator–prey system with the predator being harvested and the prey having a delay due to the gestation of prey species. By regarding the gestation delay as a bifurcation parameter, we first derive some sufficient conditions on the stability of positive equilibrium point and the existence of Hopf bifurcations basing on the local parametrization method for differential-algebra system. In succession, we also investigate the direction of Hopf bifurcations and the stability of bifurcating periodic solutions on the center manifold by employing the center manifold reduction for functional differential equations. Finally, to verify our theoretical predictions, several numerical simulations are given.


Communication and sensing are the basic functions of IOV (Internet of Vehicle), it is an efficient and economical way to realize radar sensing function by using communication signal. In this paper, it is proposed a target DOA estimation scheme based on a series of super-resolution algorithms in which the 5G upstream SC-FDMA signal is used as the radar probing signal and a uniform linear array is used to receive the target echo. Modeling analysis and simulation results show that the proposed scheme can accurately find the direction of radar target.


The acid-catalyzed photohydrations of a series of substituted styrenes and phenylacetylenes have been investigated in aqueous buffer solutions. General acid catalysis was clearly detected in five cases with a range of catalysts, and approximately linear Broensted plots gave ..cap alpha.. values in the range 0.14-0.18. The rate enhancements caused by excitation from S/sub 0/ to S/sub 1/ were estimated from comparisons with thermal hydration data to be in the 10/sup 11/-10/sup 15/ range. Treatment of the dependence of the rate constants for general acid catalysis (k/sub HA/) on the buffer pK/sub HA/ values with multiple regression analysis suggests that the Broensted plots are smoothly curved, as predicted by Eigen and by the Marcus equation. However, reliable values of the Broensted curvature could not be established. The possible catalytic reactivity of analogous triplet states was examined with a series of nitrosubstituted analogues, but no general acid catalysis could be detected. The factors controlling the detection of general acid catalysis in these photoreactions are discussed.
