Existing machine learning-based malware traffic recognition techniques can effectively detect abnormal behaviors in the network. However, almost all of them focus on a closed-set scenario in which the data used for training and testing come from the same label space. Since sophisticated malware and advanced persistent threats are evolving, it is impossible to exhaust all attacks to train a complete recognition model under the existing technical conditions. Therefore, recognition in the real network is an open-set problem, i.e., the recognition system should identify unknown and unseen attacks at test time. In this paper, we propose an uncertainty-aware method to identify known malicious traffic accurately and handle unknown traffic effectively. This method employs predictive uncertainty in deep learning as an indicator for unknown class detection. The predictive uncertainty represents the confidence in neural network predictions. In particular, the Deep Evidence Malware Traffic Recognition (DEMTR) model is presented to provide the multi-classification probability and predictive uncertainty in open-set scenarios using evidential deep learning. We demonstrate the performance of DEMTR on the MCFP dataset. Experimental results indicate that the proposed model outperforms the baseline methods in accuracy and F1-score.


Abstract Early adolescence is a dynamic stage for the development of critical consciousness, yet there are few resources focused on social justice education (SJE) in the middle grades. This article shares the findings from a study that investigated the experiences of three social justice educators as they engaged in SJE with young adolescents (YAs). We offer three key lessons associated with teaching SJE in the middle grades: (a) YAs are primed for SJ learning, (b) SJE can cultivate a learner-centered classroom community, and (c) SJE brings teacher positionality to the forefront. Subsequently, we identify instructional challenges associated with teaching SJE in the middle grades and share some of the ways in which the teachers in this study navigated these challenges.


We have detected 12 new pulsars, including four of the short-period \recycled" variety , in a survey using the Arecibo radio telescope at 430 MHz. The survey covered 680 square degrees at right ascensions 21 h through 02 h , declinations +7 through +30. Most of the region falls between galactic latitudes ?20 and ?50. The minimum detectable ux density for long-period pulsars was approximately 0.5 mJy for declina-tions +14 < < +23 , rising to 0.7 mJy at the declination extremes. For periods P < 100 ms the minimum detectable ux density increased with decreasing period, especially for large dispersion measures; at P = 1:5 ms and DM = 10 cm ?3 pc the detection threshold was about 10 mJy. Only one previously known pulsar lay within the search region, and it was detected easily. The newly discovered short-period pulsars include two isolated objects: PSR = 2:5 d). We present timing observations of three of these pulsars over 1.5{2.5yr. Reened and extended data sets for PSRs J2235+1506 and J2317+1439 have allowed the rst measurements of their proper motions, which imply velocities of (10040) kms ?1 and (7030) kms ?1 , respectively. Timing measurements of PSR J2229+2643 show that it has the smallest period derivative of any known pulsar, _ P = (1:90:2)10 ?21. We use this result to establish a new upper limit for the possible rate of change of the Newtonian constant of gravity, j _ G=Gj < 3 10 ?11 yr ?1 .


We study the relative position of three subspaces in an infinitedimensional Hilbert space. In the finite-dimensional case over an arbitrary field, Brenner described the general position of three subspaces completely. We extend it to a certain class of three subspaces in an infinite-dimensional Hilbert space over the complex numbers.


Mesoporous silica modified with titania was prepared using the sol−gel process. The structure of these composites was studied using infrared and UV−visible spectroscopies, thermogravimetry, nitrogen sorption measurements, and scanning and transmission electronic microscopies. In light of these results, a model of formation was proposed: the material is composed of a mesoporous silica matrix and small titania particles mainly located at the surface of pore walls. The thermal stability of these composites was investigated from 650 to 1000 °C. It was shown that the increase in temperature leads to the growth of titania nanoparticles associated with the shrinkage of the mesoporous structure. Nevertheless, the whole structure remains mesoporous until 850 °C; the thermal stability is thus improved compared to pure silica or pure titania. At 1000 °C, the composites are nonporous and contain crystallized anatase titania nanoparticles with a mean diameter between 5 and 10 nm embedded in the silica matrix.


The novel coronavirus has played a disastrous role in many countries worldwide. The outbreak became a major epidemic, engulfing the entire world in lockdown and it is now speculated that its economic impact might be worse than economic deceleration and decline. This paper identifies two different models to capture the trend of closing stock prices in Brazil (BVSP), Russia (IMOEX.ME), India (BSESN), and China (SSE), i.e., (BRIC) countries. We predict the stock prices for three daily time periods, so appropriate preparations can be undertaken to solve these issues. First, we compared the ARIMA, SutteARIMA and Holt-Winters (H-W) methods to determine the most effective model for predicting data. The stock closing price of BRIC country data was obtained from Yahoo Finance. That data dates from 01 November 2019 to 11 December 2020, then divided into two categories-training data and test data. Training data covers 01 November 2019 to 02 December 2020. Seven days (03 December 2020 to 11 December 2020) of data was tested to determine the accuracy of the models using training data as a reference. To measure the accuracy of the models, we obtained the means absolute percentage error (MAPE) and mean square error (MSE). Prediction model Holt-Winters was found to be the most suitable for forecasting the Brazil stock price (BVSP) while MAPE (0.50) and MSE (579272.65) with Holt-Winters (smaller than ARIMA and SutteARIMA), model SutteARIMA was found most appropriate to predict the stock prices of Russia (IMOEX.ME), India (BSESN), and China (SSE) when compared to ARIMA and Holt-Winters. MAPE and MSE with SutteARIMA: Russia (MAPE:0.7;MSE:940.20), India (MAPE:0.90;MSE:207271.16), and China (MAPE: 0.72;MSE: 786.28). Finally, Holt-Winters predicted the daily forecast values for the Brazil stock price (BVSP) (12 December to 14 December 2020 i.e., 115757.6, 116150.9 and 116544.1), while SutteARIMA predicted the daily forecast values of Russia stock prices (IMOEX.ME) (12 December to 14 December 2020 i.e., 3238.06, 3241.54 and 3245.01), India stock price (BSESN) (12 December to 14 December 2020 i.e.,. 45709.38, 45828.71 and 45948.05), and China stock price (SSE) (11 December to 13 December 2020 i.e., 3397.56, 3390.59 and 3383.61) for the three time periods. © 2021 Tech Science Press.

Internal conflict, in which a character is torn by opposing motivations, is central to drama. Actors portray such conflict in part by mimicking involuntary behaviors that occur as a result of such conflicts. In this paper, we examine the role of timing – pauses and hesitation, in particular – in internal conflict. We argue that virtual actors can be made more expressive if we can emulate the underlying structures of inhibition and conflict detection believed to operate in the human system. We discuss work in progress on this problem that uses the Twig procedural animation system.


THIS WEEK marks the 20th anniversary of the first human heart transplant ( JAMA 1967;202:23-24). Christiaan N. Barnard, MD, PhD, the surgeon who performed that transplant, recalled in a recent interview the events leading up to the historic operation. Cardiac transplantation to Barnard was merely a "new surgical technique." He began to think human heart transplants might be feasible when he read of a technique in 1959 in which the posterior walls of the recipient's atria were left behind. "Immediately, cardiac transplantation became a very straightforward surgical technique because it meant that you didn't have to anastomose the two vena cavae and the four pulmonary veins—all you had to anastomose were the two atria," he says. After studying for several months in the United States, Barnard, who is currently a scientist-in-residence at the Oklahoma Transplantation Institute, Baptist Medical Center, Oklahoma City, returned to South Africa ready to begin the patient-selection process.


In this research project, I examine the experience of the Network of Teacher Education and Pedagogical Narratives (Red de formacion docente y narrativas pedagogicas), as a collective form of organization linked to the reconstruction of pedagogical knowledge, the activation of school memory, and the stimulation of the education field. This Network is a co-participative experience of researchers, professors, and teachers-narrators from Argentina, which has established itself as a form of political-pedagogical intervention, while developing processes of formation and teacher intervention, and allowing the public display of pedagogical stories that question and challenge both educative discourses and theory. The interest of approaching this Network is associated to the intention of participating, based on this collective experience, in the debates on knowledge production in pedagogy, it is, to the intention of making public, visible, and debatable some portions of the knowledge being developed by this initiative of investigation-formation-action, as a way of intervention in the public debate on pedagogy and education How to reference thia article: Argnani, Agustina, "La Red de formacion docente y narrativas pedagogicas: una experiencia colectiva de produccion, formacion e intervencion en el campo educativo", Revista Educacion y Pedagogia , Medellin, Universidad de Antioquia, Facultad de Educacion, vol. 23, num. 61, septiembre-diciembre, 2011, pp. 157-169.

60Hz track circuits have been used for DC electrified conventional lines of Japan Railway. The train detection sensitivity of the track circuit is decided by its impedance and distribution. The model to calculate the train detection sensitivity is designed about 60 years ago and being applied still now. Nevertheless there are several occasion, where the model cannot be applied. For example, a short distance track circuit sometimes cannot be applied. To solve this problem, the author propose a new model and constants of the track circuit. The new type model and constant can be applied not only to the short distance track circuit, but also to a long distance track circuit including a turnout. With the help of a field measurement, the new model is proved that it can be applied all the kinds of 60Hz track circuits without any problems.

Background: Oral contraceptives can induce changes in lipid, lipoprotein and carbohydrate metabolism. This study is done to find out basal lipid profile in females of reproductive age group using sequential hormone therapy and with low dose estrogen combinations pills; and to study the changes in lipid profile after 3 months use of sequential hormone therapy and with low dose estrogen combination pills. Methods: Total 40 females were taken of 18-40years of reproductive age group ,subjects were divided into two groups. Group A: 20 females were subjected to sequential hormones therapy. Group B: 20 females were subjected to combined oral contraceptive pill "Mala N". Results: In Group A there was significant rise in serum cholesterol, serum TGs ,LDL, VLDL levels and LDL:HDL ratio. HDL shows fall in there levels. In Group B there was no significant change in all lipid parameters. Conclusion: There is substantial degree of metabolic changes in lipid lipoprotein profile in females with use of sequential hormones .With use of low dose estrogen and progesterone pills, there is no such deleterious effect on lipid profile and so it can be used for prolonged period. As the indications of use of sequential hormones in females of reproductive age group are now increasing in gynecological practice it would be advisable to decrease the dose of estrogen to avoid its effects on lipid profile.

It further provides practitioners with a review of coping methods utilized by refugees throughout the refugee journey in order to highlight possible protective factors practitioners may build on in the provision of mental health services. Lastly, the chapter provides an overview of current therapeutic frameworks that are culturally sensitive for counselling refugees, the challenges in the provision of mental health services, and techniques utilized by practitioners in the delivery of mental health services through evidence of research and case-based examples.


In the light of increasingly rapid climate change worldwide, and with the purpose of reduction of financial losses of dairy farmers and enabling the sustainable farming, the necessity of implementation of breeding values for heat resistance in breeding strategies, have become more and more pronounced. Estimation of breeding values requires determination of THI threshold value. Therefore, the objective of this research was to determine the THI threshold value for Holstein heifers in environmental conditions in Central Croatia. With that purpose individual test-day records of Holstein heifers with records of ambient temperature and relative humidity in the barns collected in regular milk recording from January 2006 to December 2012 were analysed. The THI threshold values for daily milk yield were determined by least square analyses of variance for each given THI value (from 65 to 76) using the PROC MIXED (SAS). The THI ≥ 65 cause significant change in Holstein heifers' daily production. Significant decrease of daily milk yield was observed at THI = 65 with estimated drop from 0.087 till 0.254 kg milk/day (THI from 65 – 76). The THI = 65, as the lowest value at which significant decrease in daily milk yield was determined was taken as the threshold value for Holstein heifers in Central Croatia.

was rarely associated with a gap of 25 mEq per liter or less. In our particular case, the calculation of the anion gap using a corrected serum sodium value but with no correction in the serum chloride or bicarbonate levels led many house officers and faculty members to think that the patient had a massively elevated anion gap and thus severe acidosis (Figure 1). In fact, the gap of 18 mEq per liter put her in the group ofpatients with hyperosmolar coma who are unlikely to have clinically important acidosis.

Abstract Oxygen formation through water oxidation catalysis is a key reaction in the context of fuel generation from renewable energies. The number of homogeneous catalysts that catalyze water oxidation at high rate with low overpotential is limited. Ruthenium complexes can be particularly active, especially if they facilitate a dinuclear pathway for oxygen bond formation step. A supramolecular encapsulation strategy is reported that involves preorganization of dilute solutions (10−5  m) of ruthenium complexes to yield high local catalyst concentrations (up to 0.54 m). The preorganization strategy enhances the water oxidation rate by two‐orders of magnitude to 125 s−1, as it facilitates the diffusion‐controlled rate‐limiting dinuclear coupling step. Moreover, it modulates reaction rates, enabling comprehensive elucidation of electrocatalytic reaction mechanisms.

The proliferative lesions and distinctive intracytoplasmic inclusion bodies of fowlpox have been the subject of excellent morphologic, biochemical, and histochemical studies.1'2 Infective virus particles have been demonstrated in the inclusions, and the virus has been shown to deoxyribonucleic acid (DNA) not were as follows: 3 hours (2, 3, 4, 5, 6 days), 6 hours (5, 7 days), I2 hours (6, 7 days), 24 hours (6 days), 48 hours (5, 6, 7 days), 72 hours (6 days), 96 hours (8 days), i week (i i days). The tissue was fixed in io per cent formalin, and paraf- fin sections were cut at 6 pi. Radioautographs were prepared by a modification of the stripping-film method of Pelc, using Kodak -io stripping film. The films were exposed for 3 to 6 weeks, developed, and stained with eosin and Ehrlich's hematoxylin by a modification of Simmel's method.13 They were then dehydrated and mounted with Permount. Controls consisted of plucked but noninfected chicks which were given injections of 5 Mc. of thymidine-H3 in o.I ml. of Hanks' BSS into the superficial subcutaneous tissue of the plucked area. At intervals from 4 to 76 hours after injection, the skin was removed and radioautographs prepared.


nately, the hearings were so heated emotionally on so many issues that clear reading was not possible. Nevertheless, it appeared that the public was suspicious of the concept. Although giving certain travelers (i.e., cars with three or more passengers) free passage was usually considered acceptable, putting a surcharge on single-occupant cars was often considered discrimination and as unconstitutional and undesirable as wiretapping. Politicians seemed particularly vulnerable to such arguments. Through an effective pricing policy, the Golden Gate District could financially support a balanced and integrated transportation system. Without an inventive pricing policy, the district cannot as effectively influence automobile and private car or van poolers. It must rely on highly attractive transit systems to control automobile use and balance its systems. In the end, the Golden Gate Bridge District may not be able to generate enough revenue to support its operations. The key to moving forward is widespread public discussion of the potential benefits that a pricing policy can produce when it is properly integrated with an overall transportation strategy.


Zebrafish have proven to be a crucial model for biological elucidations, especially heart-disease studies, owing to their remarkable regeneration capacity. Other than conventional methods, monitoring of electrocardiogram (ECG) has shown promising results recently; however, experiments were usually carried out with sedated fish, resulting in affected signals. In this work, wireless power transfer (WPT) via inductive coupling is developed to power our previously-reported miniaturized ECG sensor implanted in an adult zebrafish. This would enable continuous monitoring of freely-swimming fish without disrupting their normal activities. The WPT is achieved using inductive coupling with the transmitter (TX) located around the fish tank, and a solenoid embedded in the fish implant as the receiver (RX), with sizes of Φ77 mm × 10 mm and Φ1 mm × 10 mm, respectively. Power transfer efficiency (PTE) and an adaptive tuning method were characterized using a Vector Network Analyzer (VNA) via S-parameter measurement to ensure the ECG sensor will receive sufficient power for operating and communication.

The large divergence between productivity and workers' incomes has been becoming a reality in most countries, not just in the United States after 1980s, where labour productivity grew faster than real wages and employment. The breakdown according to Brynjolfsson and McAfee (2014) is due to technological progress, according to Bivens and Mishel (2015) the growing inequality and according to Baker (2007) the declining labour share in GDP. The main goal of this paper is to find out if the global trend of "The Great Decoupling" between productivity and labour share is a real process in the case of the countries analyzed from the Southeast Europe region. Given that Slovenia is among the most developed countries, while North Macedonia belongs to the group of developing countries that in these stages of development rely on foreign capital and cheap labour, we examine whether the process of "The Great Decoupling" between productivity and labour share is a reality in both countries. From the analysis of the trend of the movement of the average labour productivity of these two countries, it can be concluded that in both countries there is a trajectory of the movement of the labour productivity. Also, from the trend of the movement of the share of labour income and labour productivity in the case of Slovenia and North Macedonia it can be concluded that they indicate the existence of a large gap, i.e. divergence in the trajectory of motion. Also, the gap between labour productivity and the share of labour income in GDP on the example of North Macedonia, if compared to the example of Slovenia is of lower intensity. Finally, based on the results obtained from the conducted econometric analysis, we determine whether there is a need for further research or the phenomenon is a temporary deviation in the dynamics of the gap between labour share and labour productivity.


The piezoelectric properties were studied for vinylidene fluoride (VDF)-trifluoroethylene (TrEE) copolymers. The melt-crystallized films, without any stretching, showed strong piezoelectricity in the wide range of VDF molar composition. Especially for the copolymer with 55 mole % of VDF, large piezoelectric constant was obtained under a poling condition at a low electric field. The ferroelectric to paraelectric phase transition was observed at the temperature range between 60°C and 125°C for the copolymers with a VDF molar content between 37 and 80% by the measurements of dielectric and piezoelectric constants.


A method to measure electron energy loss spec- tra (EELS) of clusters with a high resolution (30 meV) has been developed and has been applied to some van der Waals clusters (Ar,, Kr,). Structures have been found which relate to the excitation of atoms on the surface and inside the cluster. An influence of the cluster size on the spectra has been observed.


Between 25 January 2020 and 7 February 2020, 22 patients admitted to Princess Margaret Hospital, Hong Kong had diagnosis of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection confirmed by real-time reverse transcription polymerase chain reaction of nasopharyngeal aspirate and throat swab. Of them, three (13.6%) patients required intensive care unit (ICU) admission. Their clinical and laboratory data as well as computed tomography (CT) images were reviewed. Herein, we review the findings from unenhanced CT scans of the thorax and serial chest radiographs in these three patients with coronavirus disease 2019 (COVID-19). The aim of the study was to provide insights into possible prognostic indicators of COVID-19 from an imaging perspective.


Author(s): Brandt, William Tyler | Advisor(s): Dozier, Jeff | Abstract: The dynamic nature in which the atmosphere and land interact can render the spatial distribution of precipitation highly variable. This is particularly the case in mountain environments where the topography is steep and the elevational variability is large. To capture this variability, we presently rely on a network of gauges, and to make these measurements meaningful we utilize statistics or models to "fill the gaps". However, the "gaps" often include vast areas of topographic variability, making model validation challenging at best. Nonetheless, these data are used in streamflow forecasts and even in some of the most technologically advanced regions in the world these forecasts can have large errors, in some cases exceeding 100% absolute error. A large part of this error is due to an inadequate understanding of the spatial distribution of mountain precipitation. Snow, unlike rain, remains roughly in place post snowfall, and can be measured both from the ground and now from the air. In my first chapter, I take advantage of this by using snow remote sensing from the Airborne Snow Observatory (ASO) to establish a methodology for measuring the spatial distribution of snowfall during a single storm. The second chapter utilizes spatial scaling of the ASO data to parse changes in snow accumulation by the principal driving force—either precipitation or wind redistribution. The third and final chapter evaluates the Weather Research and Forecasting (WRF) model's ability to replicate the spatial patterns in yearly snow accumulation as observed by ASO. Importantly, all three chapters lay the groundwork for the increased use of snow remote sensing to both help augment and evaluate existing models for precipitation monitoring and forecasting in mountain environments.


Throughout the finance and economics literature, it is widely recognized that taxation can significantly alter individual behavior and market equilibrium conditions. Yet, in the area of bonds, the impacts of taxation upon bond pricing have generally been ignored. The primary purpose of this paper is to trace out the impact of differential taxation of regular income and capital gains upon the pricing of coupon-bearing bonds.


Memory plays a crucial role in designing embedded systems. Embedded systems are constrained by the available memory. A larger memory can accommodate more and large applications but increases cost, area, as well as energy requirements. Code-compression techniques address this issue by reducing the code size of application programs. It is a major challenge to develop an efficient code-compression technique that can generate substantial reduction in code size without affecting the overall system performance. We present an efficient code-compression technique, which significantly improves the compression ratio. Two previously proposed algorithm are evaluated.


h IN LIGHT OF the recent introduction of IEEE's P1687, Internal JTAG (IJTAG) standard, the first half of this special issue is dedicated to familiarizing our readers with some of the experiences and drawbacks, implementations and troubleshooting challenges, and other economic and technical implications that the proposed standard raises. Such an evolution from the older established technologies and practices necessitates that we extract from relevant work done by industry professionals and high-profile researchers to help bring our readers up to speed. This is what we hope to have accomplished here. In true Design and Test form, we have also included some variety on the back end of the issue, to round out the P1687 articles with an international vantage on different approaches to addressing faults and defects at different levels of abstraction and integration, including the threats posed by hardware Trojans. We begin our issue on the topic of IJTAG with an article by authors in industry and academia from Texas and California that provide a new perspective on FPGA-based testers in light of IJTAG. They show that for each IC or board design, embedded FPGA testers must be reconfigured, proving difficult for creating standardized observation systems. The authors propose a methodology that effectively allows embedded vectors to automatically be retargeted to the TAP port of the FPGA. Ultimately, they show how to create a standardized Command, Control, and Observation system. Second, we present a paper from the AlcatelLucent Labs in Villarceaux, France, and New Jersey, which outlines some shortcomings in traditional vector-level control of dynamic IJTAG operations. The authors introduce state machine-level control, which forms a more comprehensive solution allowing a greater potential usage of IJTAG. Our next article, compiled by researchers in Tallinn, Estonia, proposes a new instrumentation infrastructure, based on IJTAG, which supports fault management that automatically collects and delivers detection information to operating systems. The authors specifically demonstrate the efficiency of this infrastructure. Next, we receive a breather from the deeply technical side of things, in favor of viewing the effects of the latest IJTAG on the fiscal element of our industry. Martin Keim, from Mentor Graphics, explores three industry scenarios, showing the cost of adopting IJTAG versus the costs of sticking with older, traditional systems. Then we step out of the IJTAG box and begin our latter half of the issue with an analysis of the clustering of defects on silicon wafers. A group of authors from Southeast Asia present a new, flexible three-stage automation tool aimed at improving cluster analysis, while also offering sufficient devicespecific customization to allow the accommodation of a wide variety of product types. Next, researchers from Huazhong University, China, reiterate concerns in the security of highcapacity storage of critical sensitive information, and counter these concerns by implementing integrity protection and off-chip memory encryption using the Advanced Encryption StandardVGalois/ Counter Mode. This approach is also shown to lower the overhead of memory and performance.


The private equity firm Northedge Capital has sold the Middlesbrough, England-based fine chemicals firm Fine Industries to China's Lianhe Chemical Technology for an undisclosed sum. With 220 employees, Fine Industries had sales last year of $63 million and pretax profits of $12 million. It manufactures intermediates and active ingredients for pesticide and pharmaceutical customers along with a suite of specialty chemicals. Fine Industries was acquired by Degussa in 2001 before being sold to management in 2008 and then to Northedge in 2013.


This paper addresses the potentially causal link between native attitudes and migrants' intended duration of stay. We exploit the variation in perceived anti-immigrant sentiments using information on the media exposure of Romanian migrants in Italy. A unique shock in public attitudes towards Romanian migrants allows us to identify the impact of a change in attitudes on out-migration plans. Our results suggest a significant impact of native attitudes on settlement intentions in Italy. The subgroup analysis indicates a particularly pronounced impact for low-skilled migrants, which has important consequences for the integration prospects of migrants in Italy.


ABSTRACT Xin, G.; Zhou, M.; Yang, B., and Ding, X., 2020. Energy optimization control algorithm of underwater vehicle based on model predictive control. In: Yang, Y.; Mi, C.; Zhao, L., and Lam, S. (eds.), Global Topics and New Trends in Coastal Research: Port, Coastal and Ocean Engineering. Journal of Coastal Research, Special Issue No. 103, pp. 830–834. Coconut Creek (Florida), ISSN 0749-0208. In order to improve the accuracy of energy optimization control of underwater vehicle and improve the running stability of underwater vehicle, an energy optimization control method of underwater vehicle based on model predictive control is proposed. The underwater dynamics and kinematics model of underwater vehicle is constructed, and the fuzzy feedback error tracking fusion control law of underwater vehicle is constructed with phase offset and inertia torque as constraint parameters. Fuzzy parameter fusion and adaptive parameter adjustment methods are used to optimize the energy control and model prediction of underwater vehicle. The state adaptive correction and energy optimization control design of underwater motion of robot is realized by model parameter prediction and adaptive weighted information processing. The simulation results show that the energy optimization control design of underwater vehicle using this method has good adaptability, eliminates the angle and azimuth error of energy optimization control, reduces the energy cost of the robot, and improves the stability control accuracy of the energy output of the robot.

The deliberate observation of contemporary northern hunters is one way of enhancing the interpretation of the archaeological record in the western Canadian Subarctic. The paper is based on six months of archaeological ethnography at a residential hunting camp in the mid-Mackenzie Valley, Northwest Territories, Canada, followed by archaeological excavations at the same camp of Dene hunters. The conceptual framework of this research is ethnoarchaeology, which encompasses the theoretical and methodological aspects of a comparing ethnographic and archaeological data. A model for identifying teepee remains in the absence of surficial architectural remains is presented, based on the excavation of a currently occupied tepee at the hunting camp. This model consists of a number of attributes, ranging from a central hearth to subterranean storage facilities. The probability that tepee architecture is present increases with every attribute that can be documented archaeologically. The presence or absence of architectural remains is essential in the identification of site function, and site function is the key to reconstructing the regional settlement pattern in pre-ethnographic times. There is a certain urgency in integrating first-hand accounts of northern hunters with the archaeological record, as opportunities to do so continue to dwindle with the passage of time and the ever-increasing pace of culture change in the western Canadian Subarctic. Key words: ethnoarchaeology, archaeology, ethnography, archaeological methodology, Northern Athapaskan, Dene, Mackenzie Valley, Subarctic


Summary The hemodynamic effects of endothelin-1 (ET-1) are mediated by at least two distinct receptors: ETa and ETb receptors. Recently, ETb receptor agonists (4 Ala ET-1 and IRL 1620) were developed. To investigate the role of ETb receptor activation on the pulmonary and systemic circulations, we studied the hemodynamic effects of intrapulmonary arterial injections of these receptor agonists in 10 intact newborn lambs. At rest, 4 Ala ET-1 (290–1,725 ng/kg) changed no hemodynamic variables. IRL 1620 (180–1,095 ng/kg) decreased mean pulmonary arterial pressure (PAP, 16.8% ± 15.0 and 17.8% ± 8.5, p < 0.05) and left pulmonary artery blood flow (21.6% ± 22.1 and 33.4% ± 27.7, p < 0.05) at the two highest doses only. During U46619-induced pulmonary hypertension, both 4 Ala ET-1 (3.2% ± 8.0 to 15.9% ± 6.4, p < 0.05) and IRL 1620 (8.7% ± 6.3 to 21.9% ±4.1, p < 0.05) produced selective dose-dependent decreases in PAP. The decrease in mean PAP induced by 4 Ala ET-1 and IRL 1620 was attenuated by Nω-nitro-L-arginine [an inhibitor of endothelium-derived nitric oxide (EDNO) synthesis] (16.6% ± 3.5 vs. 5.9% ± 2.3 and 16.2% ± 3.4 vs. 6.6% ± 2.8, p < 0.05) and by glybenclamide (a blocker of ATP-dependent potassium channels) (18.2% ± 7.9 vs. 7.5% ± 8.3 and 14.7% ± 3.6 vs. 6.3% ± 3.2, p < 0.05). ETb receptor activation produces selective pulmonary vasodilation during pulmonary hypertension in intact newborn lambs. The vasodilating properties are mediated in part by release of EDNO and by potassium channel activation.


This paper demonstrates a method for improving the calculation of coverage during a seabed survey mission. Called convolved coverage estimation (CCE), this method can provide the pilot with coverage information in real-time. CCE gives a conservative output and classifies less area as falsely covered when compared to using only the most likely vehicle position. A feature of this new method is that it takes into account vehicle position uncertainty. This ability to generate improved estimates of coverage is presented using field data gathered with the the Monterey Bay Aquarium Research Institute (MBARI) remotely operated vehicle (ROV) Ventana in Monterey Bay, California. For a sample 15m × 15m survey, false positive coverage was reduced by 46%.


Sportive hunting is an activity, which benefits of an increasing interest, worldwide. In this context, important regulations are implemented in the field at international level. The present study focuses the evolution of four most abundant game species taken care by the County Association of the Sportive Hunters and Fishers (CASHF) - County of Cluj, Romania, during a two years period. In the mean time, we aimed to emphasize the relationships among the occurrence of the studied game species (roebuck, wild boar, hare and deer). Basic statistics, one-way ANOVA and PCA analysis were implemented for statistical data processing, using STATISTICA v. 6.0 software. Three of four monitored specie, recorded positive very significant differences compared to optimum value (46.23 heads in roebuck, and 24.33 heads in boar, respectively), while deer stocks were also superior compared to optimum value (by 5.79 heads) but difference is statistically not significant. Hare is the single monitored game specie with lower average stocks compared to optimum (by 13.34 heads), statistically not assured at significance threshold of 5%.  PCA analysis shows that roebuck stocks are the most important game specie, followed by wild boar, hare, and deer. This hierarchy may be explained by the adaptability of the roebuck and wild boar species to the specific ecosystem conditions, and also to appropriate game management practices. The correlation matrix emphasize the relationships among the monitored game species, good tolerance between hare and deer species, and surviving competition among wild boar and hare.


This study aims to determine prospective teachers' perceptions on the basic concepts of the education system in terms of its inputs, processes and outputs through metaphors. Phenomenological analysis was used. The participants were senior students from Gaziantep University, English Language Teaching (ELT) department and pedagogic formation program students from the English Language and Literature (ELL) department. The data were collected by asking about metaphorical perceptions related to the concepts of student, parent, school, school principal, curriculum, teaching materials, principles and methods of teaching, assessment and evaluation, ethics, class management, success and graduate students. Content analysis was employed for analysis. Teacher candidates produced 528 valid metaphors related to 13 concepts of education system. Out of these, 269 metaphors were positive, 109 were negative and 150 were related to basic features of education system. While 34 prospective teachers from ELL department produced 338 metaphors, 18 prospective teachers from ELT department produced 190 metaphors. The perceptions of teacher candidates in both groups were similar in terms of teacher, student, parent, school principal, teaching materials, ethics, and success. While ELL department students identified the concepts of school and graduate more positively, ELT department students described curriculum and classroom management more positively.

In pharmaceutical and specialty chemical production, stringent product purity and quality requirements tend to cause high waste to product ratios. Therefore a large number of different types and levels of waste are leaving pharmaceutical production campaigns and need material recovery and/or adequate treatment. This paper briefly discusses the results of the application of a hybrid methodology onto a case study from the pharmaceutical industry. The hybrid methodology consists of automatic synthesis of feasible alternatives, the superstructure generation, followed by rigorous combinatorial optimization. The methodology was also applied to find the best trade-off between conflicting objectives such as economic and ecological targets. An extension to consider uncertainty pertaining to different waste loads was presented.


Objective To examine whether sodium selenite could weaken or remove the proliferative inhibition of phytohaemagglutinin(PHA)-stimulated human peripheral blood lymphocytes(PBL) induced by cispatin.Methods PHA-stimulatd human PBL were incubated with cisplatin alone or in combination with sodium selenite.Cisplatin was administered to the 72 hours cultures of PBL with three different concentration(0.05,0.20,0.50?mg/L) at 24 hours after PHA stimulation.Sodium selenite was added with a single dose of 0.05?mg/L at 0 hour or at 24 hours after PHA stimulation for different treatment.Mitotic indices(MI) of transformed lymphocytes were tested at the end of 72 hours cultures.Results Sodium selenite at dose of 0.05mg/L enhanced MI of transformed lymphocytes in response to PHA stimulation by 42.8%(P0.05) and 13.7%(P0.05) above the control values when the chemical was administered respectively at 0 hour and at 24 hours after PHA stimulation.When cells were exposed to cisplatin from 0.05mg/L to 0.20mg/L,Mi of transformed lymphocytes had no significant alteration compared with control cells,however,when exposed to cisplatin at 0.50mg/L,MI was reduced by 54.5%(P0.001) compared to control cells.Proliferative inhibition caused by cisplatin at 0.50mg/L were counteracted and a normal MI was obtained when the cells were pretreated with sodium selenite,but when sodium selenite was simultaneously added with cisplatin,the MI inhibition by the agent could only partially enhanced.Conclusion Sodium selenite at 0.05 mg/L could directly promote cell proliferation when PBL were treated with it alone.When it was used as protectant to cotreat PBL in combination with cisplatin,it can reduce cisplatin cytotoxicity,and protect PBL against the antiproliferative effect of the agent.More effective results could be obtained when it was administered to the system at the beginning of the culture.


Let θ = T (F ) be an interesting parameter of a distribution function F , where T (.) is a functional of F . One simple example is T (F ) = ∫ xdF (x), which is the mean parameter of the distribution F . Another example is T (F ) = ∫ (x − ∫ ydF (y))dF (x), which is the variance parameter. Let X1, . . . , Xn be an i.i.d. sample from F , and we use F̂n to denote the empirical distribution which puts mass 1/n on each of Xi's. An estimate of the parameter θ = T (F ) can often be constructed by using θ̂ = T (F̂n). For example, the estimator for the population mean θ = ∫ xdF (x) is the sample mean

This paper presents some experimental investigations about the origins of the anisotropic behaviour in cyclic loadings of AA2017 aluminium alloy. In the first step, fatigue damage evolutions were quantified for controlled proportional cyclic loadings in axial and shear directions. In this stage, the aim was to confirm the anisotropic mechanical behaviour, which has recently been revealed. To this end, several models of fatigue damage quantification were used. After a comparative study between the obtained results we confirmed the anisotropic nature of the used material. In the second step, microstructural investigations were performed in order to understand the origins of the anisotropic mechanical behaviour. We used scanning electron microscopy to analyse phases and precipitates in the transversal and the longitudinal sections. It was deduced that the structure and the morphology of these entities are responsible for the anisotropic behaviour of the used aluminium alloy. Moreover, the results obtained using Kikushi diagrams, poles figure and inverse poles figures have also confirmed these conclusions. Indeed, these results have shown great differences in crystallographic texture of the material.

Aim. To study pancreatic changes in acute pancreatitis with internal pancreatic fistula and to assess the results of retroperitoneoscopic sanations for this pathology. Material and Methods. Contrast-enhanced CT was made in 30 patients. Localization and depth of necrosis were evaluated in sagittal, axial and coronal sections. Swelling and infiltration of retroperitoneal fat up to pelvic floor aperture were the criteria for evaluating severity of retroperitoneal fat lesion. All patients were divided into two groups. The first group included 15 patients with pancreatic head or isthmus necrosis and viable parenchyma of body and tail who underwent retroperitoneoscopic drainage of retroperitoneal fat in 4–5 hours after disease onset. The second group consisted of 15 patients with various forms of pancreatic necrosis who were operated only at the stage of infected pancreatic necrosis. Results. In the first group hospital-stay was 45 ± 5.3 days. External pancreatic fistula was observed in all patients that was closed within 4.8 ± 1.1 months after surgery. Deaths were absent. Postoperative ventral hernia was not observed. Pancreatic pseudocysts occurred in 3 (20%) patients. Mean hospital-stay in the second group was 80 ± 5.3 days, mortality rate – 33.3%. External pancreatic fistula formed in 2 (13%) patients, postoperative ventral hernia – in 3 (20%) cases, pancreatic pseudocyst – in 3 (20%) cases. Conclusion. Contrast-enhanced computed tomography visualizes internal pancreatic fistula and gives information for differentiated surgical approach in acute pancreatitis patients. External drainage of retroperitoneal fat is pathogenetically proved treatment of patients with internal pancreatic fistula and acute severe pancreatitis.


The present study investigates whether consumers purchase the amount they plan to buy, considering the levels of informational and utilitarian benefits of the brands. The design was a natural experiment between subjects. A questionnaire was applied to 1016 consumers who entered a large retail store. At the exit, their purchases were examined. Probit regressions of amount bought as a function of amount planned, including brands' benefit levels as factors, showed a significant interaction effect. They demonstrated that consumers buy more units of brands with low benefits than with high benefits when they plan to buy above the average of other consumers.


This paper attempts to elucidate the long-term impact of basic education on income inequality in Brazil. It does so, first, by examining how investment in basic education affects incomes and, second, by assessing the extent to which government involvement in the financing of education services and the taxing of the returns to education investment contributes to the achievement of a more equitable distribution of income. On the basis of the empirical evidence available in Brazil, it is possible to suggest that (i) education per se cannot significantly reduce inequality, (ii) government policies in terms of education subsidies and taxes on lifetime earnings do not show a clear redistribution pattern, and (iii) there exist effective policy tools in the area of employment, education wastage, cost recovery practices which could help bridge the gap between rates of return to education and reduce income inequality.


The ovulatory cycle is the result of a tightly regulated system of crosstalk between reproductive hormones generated in the brain and ovary. The complex hormone feedback gives rise to the characteristic oscillatory behavior of the menstrual cycle. Altered hormone regulation may disrupt the cycle, leading to abnormal ovulation and/or fertility. The sheer complexity of this system poses a challenge to identifying precise mechanisms of dysfunction. However, mathematical approaches have been useful in examining pathophysiology, even when precise biological mechanisms are unknown. I will discuss mathematical models of ovulation in the context of general dynamics, the nature of dysfunction, clinical implications, and an algorithmic approach for dataand biology-driven model reduction.


Significance The botanical value of angiosperm leaf shape and venation ("leaf architecture") is well known, but the astounding complexity and variation of leaves have thwarted efforts to access this underused resource. This challenge is central for paleobotany because most angiosperm fossils are isolated, unidentified leaves. We here demonstrate that a computer vision algorithm trained on several thousand images of diverse cleared leaves successfully learns leaf-architectural features, then categorizes novel specimens into natural botanical groups above the species level. The system also produces heat maps to display the locations of numerous novel, informative leaf characters in a visually intuitive way. With assistance from computer vision, the systematic and paleobotanical value of leaves is ready to increase significantly. Understanding the extremely variable, complex shape and venation characters of angiosperm leaves is one of the most challenging problems in botany. Machine learning offers opportunities to analyze large numbers of specimens, to discover novel leaf features of angiosperm clades that may have phylogenetic significance, and to use those characters to classify unknowns. Previous computer vision approaches have primarily focused on leaf identification at the species level. It remains an open question whether learning and classification are possible among major evolutionary groups such as families and orders, which usually contain hundreds to thousands of species each and exhibit many times the foliar variation of individual species. Here, we tested whether a computer vision algorithm could use a database of 7,597 leaf images from 2,001 genera to learn features of botanical families and orders, then classify novel images. The images are of cleared leaves, specimens that are chemically bleached, then stained to reveal venation. Machine learning was used to learn a codebook of visual elements representing leaf shape and venation patterns. The resulting automated system learned to classify images into families and orders with a success rate many times greater than chance. Of direct botanical interest, the responses of diagnostic features can be visualized on leaf images as heat maps, which are likely to prompt recognition and evolutionary interpretation of a wealth of novel morphological characters. With assistance from computer vision, leaves are poised to make numerous new contributions to systematic and paleobotanical studies.


The purpose of the present study was to investigate the relationships among sustainable behavior, study engagement, and happiness. The participants were 202 undergraduate students. The present study used structural equation modeling to examine the relationship among variables, and two models were examined. The analyses revealed that the present data best fit Model 1, in which sustainable behavior was directly associated with happiness and mediated by study engagement (χ 2 (24) = 46.743, Turker-Lewis Index = 0.933, Comparative Fit Index = 0.955, Root Mean Square Error of Approximation = 0.06). The results indicate that sustainable behavior affect happiness directly. Additionally, sustainable behaviors affect happiness indirectly by mediation of study engagement. In closing, implications for educational practices are discussed.


Spring balance weighing design is a model of an experiment in which the result can be presented as a linear combination of unknown measurements of objects with factors of this combination equalling zero or one. In this paper, we assume that the variances of measurement errors are not equal and errors are not correlated. We consider D‑optimal designs, i.e. designs in which the determinant of the information matrix for the design attains the maximal value. The upper bound of its value is obtained and the conditions for the upper bound to be attained are proved. The value of the upper bound depends on whether the number of objects in the experiment is odd or even. Some methods of construction of regular D‑optimal spring balance weighing designs are demonstrated.


Granted that studies on e-commerce adoption by small business in developing countries has received a significant attention in the past decade, most of the studies recorded in the literature were mainly focused on manufacturing, distribution and service sector. Limited attention had been given to agribusiness sector despite its significance to the economy. Many studies have adopted Rogers's innovation-decision process model to analyze the adoption process. However, only a portion of the model were used in those studies. This paper discusses and proposes Rogers model incorporating all elements of the innovation-decision process model including the stages of innovation-decision and its influencing factors such as prior conditions, communication channels, characteristics of the adopter, and the perceived characteristics of e-commerce; to gain a better understanding on e-commerce adoption process. This paper spotlights Indonesian small agribusiness whereby e-commerce adoption studies still scarce.


From ancient period itself, Kerala holds a rich heritage of a plethora of curing practices. Several systems of treatments have emerged and flourished here to offer cure and relief to patients. Kerala, the birthplace of ayurveda, still attracts patients from all over the world. In addition to it, several ethnic medical systems also have rooted in Kerala. Generally these systems offer vital thrust on curing diseases with immediate and minimal effect. The aspect of relief for those beyond cure has yet to be acquired enough attention in these systems. Moreover the emotional dimensions of miseries of those on the verge of death have not attained sufficient momentum. The system of palliative care is a novel attempt towards this limited thrust area. Malabar region in Kerala has become a forerunner in it by showing way for the entire Kerala. Now the concept is slowly gaining momentum all over the state even seeking the attention of organised government mechanism. Hence it would be worthy to trace the history and functioning of palliative care movement and the present paper tries to evaluate the nature of evolution and role of palliative movement in the medical system of Kerala.


Let Í2 be a bounded open set of E" (n > 1) with "fractal" boundary T . We extend Hermann Weyl's classical theorem by establishing a precise remainder estimate for the asymptotics of the eigenvalues of positive elliptic operators of order 2m (m > 1) on Í2 . We consider both Dirichlet and Neumann boundary conditions. Our estimate—which is expressed in terms of the Minkowski rather than the Hausdorff dimension of Y—specifies and partially solves the Weyl-Berry conjecture for the eigenvalues of the Laplacian. Berry's conjecture—which extends to "fractals" Weyl's conjecture—is closely related to Kac's question "Can one hear the shape of a drum?"; further, it has significant physical applications, for example to the scattering of waves by "fractal" surfaces or the study of porous media. We also deduce from our results new remainder estimates for the asymptotics of the associated "partition function" (or trace of the heat semigroup). In addition, we provide examples showing that our remainder estimates are sharp in every possible "fractal" (i.e., Minkowski) dimension. The techniques used in this paper belong to the theory of partial differential equations, the calculus of variations, approximation theory and—to a lesser extent—geometric measure theory. An interesting aspect of this work is that it establishes new connections between spectral and "fractal" geometry.

The device of the present application is configured to provide two different frequency vibrations (eg, sound waves and ultrasound waves) toward the skin of the subject. The combination of two different frequencies can improve the dermal injection function and can be used, for example, for transdermal delivery of topical formulations.


A systematic study has been conducted to assess the performance of the TVD schemes for practical flow computation. The viewpoint adopted here is to treat the TVD schemes as a combination of the standard central difference scheme with numerical dissipation terms. The controlled amount of numerical dissipation modifies the computed fluxes to ensure that the solution is oscillation-free. Four variants of TVD schemes, two with upwind dissipation terms and two with symmetric dissipation terms, have been studied and compared with the conventional Beam-Warming scheme for inviscid and turbulent axisymmetric flow computations. The results obtained show that all four variants can accurately resolve the shock and flow profiles with fewer grid points than the Beam-Warming scheme. The convergence rates of the TVD schemes are also substantially superior to that of the Beam-Warming scheme. The combination of high accuracy, good robustness and improved computational efficiency offered by the TVD schemes makes them attractive for computing high-speed flow with shocks. In terms of the relative performances it is found that the symmetric schemes converge slightly faster but that the upwind schemes are less sensitive to the number of grid points being employed.


170 Background: Aromatase inhibitors are widely used in treatment of estrogen receptor positive breast cancer. Many patients experience significant arthralgias, which may lead to early cessation of therapy. Blue Citrus, a mix of Chinese herbs formulated in our community, had anecdotal reports of success in alleviating these symptoms. We objectively evaluated its activity in symptomatic patients.

METHODS
Breast cancer patients with significant arthralgia on aromatase inhibitors were enrolled in a prospective fashion to a double blind crossover placebo controlled trial. Each patient received either Blue Citrus (BC+P) or a placebo (P+BC) for three months and then crossed over to the opposite treatment for an additional three months. Symptoms were measured over the course of treatment.

RESULTS
A total of 37 patients enrolled on the study. There were 6 early withdrawals, which left 31 evaluable patients. Visual Analogue Score (VAS) for both groups was similar at baseline at 4.9 and 5.1 for the BC+P and P+BC groups, respectively. At 30 days the BC+P score was 3.4 vs. the P+BC of 4.7 showing clearly improved symptom control in the BC+P group. The P+BC group did however approach the BC+P group by 90 days. At crossover the BC+P group experienced a spike in symptomology when changed to placebo that didn't appear for the P+BC group. When compared to baseline, mean VAS score on Blue Citrus was 2.98 (p=0.001) versus mean VAS score on placebo 3.92 (p=0.0203). By study end (180 days) the VAS scores for both groups were closer at 2.6 BC+P vs. 3.0 for P+BC but BC+P still maintained lower VAS scores.

CONCLUSIONS
Blue Citrus improved symptoms associated with aromatase inhibitor use. Patients who received Blue Citrus in the first arm had rapid improvement in symptoms and experienced return of symptoms when converted to placebo. All patients averaged lower VAS scores on Blue Citrus however at 6 months the difference between the arms became less pronounced.


The study investigates the influence of performance management system consistency on employee work engagement. Drawing on the 'job demands-resources model' and 'regulatory focus theory', it was hypothesized that when employees perceive their performance management system to be consistent, they develop positive outcome expectations, which primes their achievement-oriented motivation (promotion regulatory focus) and increases their engagement. Responses were collected from 779 employees belonging to three large, multi-national organizations in India. Data were analyzed using PLS-SEM package ADANCO and Hayes' PROCESS macro. Support was found for a moderated-mediation model. Specifically, promotion focus was found to mediate the relationship between performance management system consistency and work engagement, while positive affect moderated the relationship between performance management system consistency and promotion focus. The study advances scholarly understanding of the psychological impact of performance management systems on employees by clarifying the cognitive-affective processes underlying this relationship. The study also adds to the literature on work engagement by establishing consistency as a key attribute for performance management systems to act as a 'job resource' for employees and enhance their engagement. The study makes a strong case for organizations to look at performance management as an integrated system and move away from an insular focus on performance-related practices such as appraisals.


In the Japanese welfare regime described as familialism, child-rearing and elderly care have been regarded as the responsibility of the family. As such, in Japan, policies for the " socialization of care " have been implemented since the 1990s. In fact, in both child care and elderly care, the advance of socialization can be observed. Howev-er legally and practically, family responsibility in care has been firmly maintained, so even now, a considerable amount of care is left to the family. In order to promote the " socialization of care, " it is necessary to establish a " high-quality quasi-market " of care services; therefore, both considerable financial resources and the reinforcement of the regulations are indis-pensable. As for what follows the " socialization of care, " it is necessary to re-define " family care " in each of the domains of child care policy and elderly care policy. Without devaluing care in society, to achieve the " socialization of care, " the " logic of escaping from family care " and the " logic of protecting family care " are required.


This report presents approaches for utilizing Probabilistic Risk Analyses (PRA's) to determine risk importances. Risk importances are determined for design features, plant operations, and other factors that can affect risk. PRA's can be used to identify the importances of risk contributors or proposed changes to designs or operations. The objective of this report is to serve as a handbook and guide in evaluating and applying risk importances. The utilization of both qualitative risk importances and quantitative risk importances is described in this report. Qualitative risk importances are based on the logic models in the PRA, while quantitative risk importances are based on the quantitative results of the PRA. Both types of importances are among the most robust and meaningful information a PRA can provide. A wide variety of risk importance evaluations are described including evaluations of the importances of design changes, testing, maintenance, degrading environments, and aging. Specific utilizations are described in inspection and in reliability assurance programs, however the general approaches have widespread applicability. The role of personal computers and decision support programs in applying risk importance evaluations is also described.


A method for correcting or adjusting the lateral critical dimension (ie, length and width) which is formed in a layer on a substrate of an element using a dry etching process. One or more thin intermediate layers are added to the layer in which the structural element is to be generated. As soon as an intermediate layer is achieved during the etching process, an etching process for correcting and / or adjusting of the lateral critical dimensions is carried out prior to etching through the intermediate layer and the resume Schichtatzung.


Reaction of phenylpyruvic acid with semicarbazide afforded 6-benzyl-2H-[1,2,4]triazine-3,5-dione ( 1 ) which upon oxidation with potassium dichromate furnished 6-benzoyl-2H-[1,2,4]triazine-3,5-dione ( 2 ) in good yield. Constructing pyrazolo[3,4-e][1,2,4]triazine system ( 4 ) was achieved by reacting 2 with arylhydrazines in ethanolic solution. However treatment of 2 with the less reactive heteroarylhydrazines gave only the corresponding hydrazones ( 3 ). Attempt for constructing 1,2,4,5,10-pentaaza-dibenzo[a,d]cyclohept-3-one ( 7 ) from 2 was failed and (benzoimidazol-2-yl) [1,2,4] triazine derivative ( 6 ) was the only product. Reaction of 1 with phosphorus pentasulphide afforded compounds 8 and 9 . Compound 8 was transformed to the hydrazino compound 14 , which led to the construction of triazolo[4,3-d] [1,2,4]triazine system. Thus compounds 15 and 16 were obtained by reacting 14 with carbon disulfide or acetic anhydride respectively. Attempt to couple 8 with chloroacetic acid failed, while it's known isomer 10 led to the formation of thiazolo [2,3-c] [1,2,4]triazine derivative ( 13 ). Simple theoretical calculation using AM1 and PM3 semiempirical Hamitonian provided rational ways to correlate the reactivity with structure proposed.


This paper presents a study of the electrical and structural properties of inverted modulation‐doped GaInAs/InP heterostructures grown by low‐pressure metalorganic vapor phase epitaxy. First, the thickness of the GaInAs layer was optimized in lattice‐matched samples to find the smallest thickness in which high Hall mobility is observed. Next, in a section closest to the InP the In content was varied. A steady increase of mobility with indium composition was observed. A maximum of 450 000 and 15 500 cm2/V s was obtained for a 10‐nm‐thick Ga1−xInxAs layer with x=0.77 at 6 and 300 K, respectively. Channels with higher indium content exceed the critical thickness and mobility drops off sharply. The decreasing mobility correlates with the formation of misfit dislocations at the interface indicating increasing scattering processes of the GaInAs layer.


Abstract The addition of trastuzumab to cytotoxic chemotherapy has improved outcomes for patients with HER2 positive breast cancer. Increased survival coupled with limited blood-brain barrier (BBB) penetration of trastuzumab may contribute to the increased incidence of brain metastasis in these patients. Half of these patients die of intracranial disease progression rather than extracranial disease. Therefore, strategies to improve survival must include increased CNS disease control in these patients. Lapatinib crosses the BBB and demonstrates modest activity against intracranial metastases. Based upon preclinical data and results of a phase I study, we hypothesized that lapatinib plus WBRT /SRS can improve the intracranial disease control compared to WBRT / SRS alone. A randomized phase II trial of WBRT (37.5 Gy/3 weeks) or SRS plus or minus concurrent lapatinib (daily 1000 mg for 6 weeks) was initiated. CNS penetrating HER2 targeted therapy is permitted throughout the study, but patients not on trastuzumab, pertuzumab or any other breast cancer therapy at study entry are not permitted to begin this therapy while on protocol treatment, but may begin it 24 hours after completion of protocol treatment. Eligibility includes HER2+ breast cancer with at least one measurable, unirradiated parenchymal brain metastasis. The two populations targeted for accrual include patients with 1) newly diagnosed, multiple brain metastases or 2) progressive brain metastases after stereotactic radiosurgery (SRS) or surgical resection of 1–3 metastases. Prior lapatinib is allowed. Patients are stratified by breast-specific graded prognostic assessment; use of non-CNS penetrating HER2 targeted therapy; and prior SRS or surgical resection. The primary endpoint is complete response rate in the brain 12 weeks after WBRT. Secondary endpoints include objective response rate, lesion-specific response rate, CNS progression-free survival, and overall survival. 140 of 143 target accrual have enrolled (4/22/2019).


Transient quadriplegia is a rare injury that can change the course of an athlete's career if misdiagnosed or managed inappropriately. The clinician should be well versed in the return-to-play criteria for this type of injury. Unfortunately, when an unknown preexisting syrinx is present in the athlete, there is less guidance on their ability to return to play. This case report and review of the current literature illustrates a National Collegiate Athletic Association (NCAA) Division I football player who suffered a transient quadriplegic event during a kickoff return that subsequently was found to have an incidental cervical syrinx on magnetic resonance imaging. The player was able to have a full neurologic recovery, but ultimately he was withheld from football.


The temporal muscle is involved as a musculo-tendinous brake in working to block the dislocation. The reconstitution or the addition of this brake can be realised by the shortening of the horizontal fibres or by advancing the articular eminence realising an arthroplasty and an increase in the action of the temporal brake.


These studies are based on the investigation carried out on the cation-exchange and adsorption bahavior of a natrolite-type natural zeolite collected as a geological specimen as a powdered sample. Cd"-natrolite was prepared with saturated aqueous cadmiun(II) sulfate solution with continuous shaking at 60° for maximum interaction. A portion of this exchanged derivative was then heated over a Nicker burner for several days in a nickel crucible. Both the original and the preheated Cd I I -zeolite samples were also interacted with gaseous H 2 S and liquor ammonia to study their sorption capacity and preheating affects. All the derivatives and the original zeolite before and after heating were analyzed by XRD, FTIR and thermal methods.


The US Naval Research Laboratory (NRL) is the world leader in the development of high energy excimer laser science and technology [1] . The argon fluoride (ArF*) laser can be scaled in power and energy to become a good candidate for direct or indirect driver for inertial confinement fusion (ICF). The deep UV light (193 nm) provides uniform target irradiation and broad native bandwidth (5 to 10 THz), suppresses laser plasma instabilities, and has intrinsic efficiency of more than 16 %. In this work we present the progress in modeling the kinetics and radiation of an electron beam ( e -beam) pumped ArF* laser relevant to NRL Electra facility. The modeling is based on the NRL Orestes suit of codes. The most important parameters used for guiding the experiments and monitoring the Orestes predictive capabilities are the laser yield and ASE. Here we present some numerical simulations for 0.5–1 MW⁄cm 3 e -beam power and total pressure 12–20 psi. We scan the range of pressures for which experiments are typically performed [2] . The ASE is a small fraction of the laser yield, on the order of 1-10 %. The numerical simulations show that the laser yield is not very sensitive to total pressure, which should be close to 1 atm, but very sensitive to F 2 content: maximum lasing is observed at 0.5±0.2% F 2 in Ar. The laser yield increases with e -beam power deposition until it reaches an optimum e -beam power beyond which the lasing decreases because most of the ArF* molecules are dissociated by electron impact or lost in neutral-neutral collisons with Ar and F 2 .


The problems of construction and using of textbooks for bilingual teaching are explored and some suggestions have been proposed based on the bilingual teaching practice in BUPT.


The online detection of longitudinal slope road is very helpful to improve the driving safety for intelligent vehicles. A detection method for longitudinal slope road based on accelerator pedal position and vehicle velocity is proposed. The vehicle's dynamic model is established according to the force analysis for the vehicle on longitudinal slope road. Then a function of slope angle is derived from the driven force and velocity of the vehicle. The function between the slope angle and the accelerator pedal position and vehicle velocity can be obtained by combining the relation between the driven force and the accelerator pedal position. Thus, the slope angle can be directly computed with the accelerator pedal position and the vehicle velocities at two samplings. Simulation results verify the effectiveness of the proposed method.


The concepts of 'commodity' and of 'simple commodity production' in the work of Marx and his interpreters are examined as a necessary departure point for the analysis of value and price in a Mexican peasant‐artisan stoneworking industry. The labour theory of value, which posits a close relationship between market price and average embodied labour cost of commodities in a peasant‐artisan economy, is applied to the stone‐working industry and is shown to have explanatory power in both the qualitative and quantitative sense. This analysis leads to the conclusion that the labour theory is a necessary tool for discerning and approximating the fundamental role of the labour process, as well as the structure of production relations, in determining the nature and conduct of exchange activities in a peasant‐artisan commodity/market economy.


The problem of library co‐operation is again in the forefront following the decision of the National Central Library that it will not be responsible for applications for British books published after 31st December, 1958. The responsibility for books to be published after that date devolves therefore upon the ten British regions and the hope has been expressed that these regions should be self‐sufficient in themselves, each devising some means of subject specialisation which will insure that all books, apart from a few excepted classes, are covered in one or other library within the region. The latest indications are that there may be some co‐operation between regions reducing the responsibility of each region to that for only a part of the whole subject field.

This study aimed to explore supportive needs of caregivers when caring for patients with chronic illness during hospitalization. A descriptive qualitative study was conducted at a tertiary hospital and purposive sampling was used to recruit 13 participants. Eligibility criteria included primary caregivers of patients with chronic illness. Data were collected via interviews. Results were analyzed using thematic analysis. Five themes were derived, portraying caregivers' perceptions during the patients' hospitalization. The caregivers generally appreciated patient care provided by healthcare professionals. However, they expressed the needs for complete and updated information regarding the patients' conditions and training programs to enhance their knowledge and skills. Furthermore, they requested services to minimize their emotional and financial issues. Addressing caregivers' supportive needs is important to augment the recovery of the patients and to reduce the rate of readmissions. Caregiver support programs can be offered to minimize emotional stress and to enhance their knowledge and skills.


We contend that the content of the required MBA strategy course in top-tier business schools has moved away from interdisciplinary thinking and practice toward an almost exclusive emphasis on theory and analysis. The once accepted Harvard model of capstone integration and learning-by-doing through case discussion is now much less in vogue. Consequently, strategy students today tend to experience a rather abstract approach to learning about strategy presented through the limited prism of a theoretical discipline. Even classroom discussions of cases are often guided by instructors to confirm the utility of a particular theoretical framework, instead of serving as an open-ended discussion of problems and solutions. After presenting our evidence and arguments against the current trend, we present some examples of MBA programs that give more emphasis to practice, including USC's Executive MBA program, where priority is placed on integration and implementation without sacrificing, we believe, essential theories and analytical skills. Finally, we explore the implications from our analysis for additional solutions in other strategy teaching contexts.


Background: Suicide is a devastating problem. It is to some extent preventable if we are aware of its factors. These factors vary according to community, cast and creed. Many studies were conducted at many places of the world but there is none in Chittagong. To know the high risk factors of suicide in Chittagong we have conducted the study.Methods : It was a descriptive study. Secondary data were used. All suicidal reports of Chittagong mortuary in 2012 were studied. Collected data were managed manually. Results were contrasted with recent studies of home & abroad.Results: Total 165 reports were studied. Majority of the victims 128(78%) were of 15-45 years age group. Male female ratio was 49: 51. Married victims were 109(66%). Muslims 125(76%). Majority of the victims 104(63%) were poorly literate (<SSC). Commonest profession of the victims was 'housewife'57(35%). Next professional group was lower subordinate staffs 49(30%). Commonest method of suicide was Hanging 83(50%). Family feud was the commonest cause of suicide and it was 72(44%).Conclusion: Commonest demographic factor of suicide in Chittagong is 'Family Feud' It is mostly manageable and thus we can prevent suicide occurrence significantly. So, everybody should come forward to remove causes of family feud and others for a noble humanitarian cause.Chatt Maa Shi Hosp Med Coll J; Vol.16 (2); July 2017; Page 14-13


The Lipid/oil was extracted from reduced dried primary sewage sludge particle using soxh let extraction method with the mixture of chloroform and n-hexane in ratio 2:1 as the extracting solvent. The extracted oil was transesterified to produce biodiesel. The lipid gave 7.969% percentage yield with density of 0.855g/ml, specific gravity value of 0.855. The chemical analyses revealed acid value of 0.84mg/NaOH/g, free fatty acid value of 0.40% and saponification value was 1.30mg. The lipid/oil was brownish black in colour with a pungent smell. The physicochemical analyses of the biodiesel produced gave a percentage yield of 32% biodiesel, density of 0.834Kg/ml, pH value of 8.97, specific gravity of 0.834, acid value of 0.29mg KOH/g,saponification value of 1.30 mg, free fatty acid value of 0.145 It is thus apparent that the feedstock (primary sewage sludge) may be a good source for the production of biodiesel.


Simultaneous density and velocity turbulence statistics for Rayleigh–Taylor-driven flows at a moderately high Atwood number ( $A_{t}$ ) of $0.73\pm 0.02$ are obtained using a new convective type or statistically steady gas tunnel facility. Air and air–helium mixture are used as working fluids to create a density difference in this facility, with a thin splitter plate separating the two streams flowing parallel to each other at the same velocity ( $U=3~\text{m}~\text{s}^{-1}$ ). At the end of the splitter plate, the two miscible fluids are allowed to mix and the instability develops. Visualization and Mie-scattering techniques are used to obtain structure shape, volume fraction profile and mixing height growth information. Particle image velocimetry (PIV) and hot-wire techniques are used to measure planar and point-wise velocity statistics in the developing mixing layer. Asymmetry is evident in the flow field from the Mie-scattering images, with the spike side showing a more gradual decline in volume fraction than the bubble side. The spike side of the mixing layer grows 50 % faster than the bubble side. PIV is implemented for the first time in these moderately high-Atwood-number experiments ( $A_{t}>0.1$ ) to obtain root-mean-square velocities, anisotropy tensor components and Reynolds stresses across the mixing layer. Overall, the turbulence statistics measured have shown different scaling compared to small-Atwood-number experiments. However, the total probability density functions for the velocities and turbulent mass fluxes exhibit behaviour similar to small-Atwood-number experiments. Conditional statistics reveal different values for turbulence statistics for spikes and bubbles, unlike small-Atwood-number experiments.


In this paper, we propose an analog self-interference cancelation scheme for full-duplex wireless orthogonal frequency-division multiplexing (OFDM) systems. Since the delay of the echo path is presented as a phase rotation of the baseband transmit signal at each subcarrier, the proposed scheme uses the rotated baseband signals to emulate self-interference signals for analog cancelation. While the conventional analog cancelation schemes are matched only to a single frequency, the proposed scheme can perfectly cancel self-interference at all subcarriers, as long as the phase and the gain of the echo path are given precisely. To obtain accurate estimates of the phase and the gain, we also suggest a maximum-likelihood (ML) estimator for use in the proposed scheme. Numerical results verify that the proposed scheme provides significantly enhanced suppression performance compared with the conventional scheme.

Abstract A research group on forest products from School of Agriculture – Sao Paulo State University. Brazil developed a portable hardness tester for wood, which is based on a displacement transducer and an embedded electronic processor for dynamic evaluation of hardness. This paper presents the results of calibration tests of the equipment, carried out on seven species of Eucalyptus. A new methodology for dynamic hardness calculation has been introduced, which relays on the reaction force of the indentation, while the measurements of indentation depth are performed under load. A moderate to strong linear correlation to Janka hardness and its variations were found. This new approach avoids the classical problems of Brinell hardness test in terms of "sinking-in" (causing diffuse edges) and elastic recovery of the indentation.

Develops a large deformation theory to describe the interaction of the red cell membrane with the endothelial glycocalyx. This model provides the basis for understanding the unusual lift off phenomenon observed for red cells in closely fitting capillaries. Using effective medium theory, the authors first show that the local Darcy permeability of the fiber matrix is a highly nonlinear function of compression. As a consequence, the pressure distribution on the moving cell membrane surface is three orders of magnitude greater than in classical lubrication theory. These results support the observation that if a red cell starts from rest, it will exhibit a striking popout phenomenon in which it will quickly lift off the surface and then glide near the edge of the matrix layer, which is in sharp contrast to existing models where there is a thin fluid layer between the matrix and the membrane.


BHARAT SHARMA QR CODE The drug Dapsone is a component of the World Health Organization multidrug therapy being used against leprosy. Although it has shown a good efficacy during the years, a few subjects develop adverse drug reactions associated with dapsone .We report a case of a patient who was prescribed dapsone as part of multiple drug therapy for leprosy following which he developed Dapsone induced Hypersensitivity Syndrome (DHS). He was prescribed steroids with a tapering dose. His condition worsened after weaning of the oral steroids. He also developed steroid-induced diabetes which was stabilized using anti-diabetic drugs.
