SiC-MOSFETs with high reliability have been desired for electric vehicles. We classify commercial SiC-MOSFETs into "heavily nitrided" and "lightly nitrided" based on time-dependent gate-current characteristics of fabricated devices. In "heavily nitrided" devices for higher mobility, high-voltage gate pulse for screening of B-mode (extrinsic defects) causes hole-trapping near the SiO2/SiC interface through impact ionization. This phenomenon leads to an increase in gate current as well as a negative shift of threshold voltage. Moreover, this is enhanced at low temperatures (-60, 25°C). Thus, high-temperature (200°C) screening is preferable. In addition, the relation between Weibull slopes for time-to-breakdown and charge-to-breakdown is closely examined.


965 percent decrease in resistance in an airway in which the wall area was 45 percent. Since an increase in airway wall thickness is one of the pathogenetic mechanisms that leads to the decrease in maximal expiratory flow in patients who have COPD,2 it would be expected that those patients with more severe baseline airflow obstruction would have thicker airway walls. Thus, another explanation for the relationship between starting FEy, and bronchodilator response is equal smooth muscle relaxation irrespective of starting FEy1, but a greater effect of the relaxation in those with the most inflamed and thickened airway walls. A similar mechanism may explain the exaggerated airway narrowing that develops in patients who have COPD in response to inhaled pharmacologic agents that stimulate smooth muscle contraction. A 30 percent muscle shortening in an airway in which the airway wall contributes 20 percent of the total area within the smooth muscle layer will result in a 600 percent increase in resistance, while the same amount of smooth muscle shortening will increase the resistance to 1,300 percent of baseline in an airway in which the wall area makes up 30 percent of the total area. These calculations show that changes in measures of resistance and maximal flow are not linearly related to changes in airway smooth muscle length. Similarly, changes in smooth muscle length, even if precisely known, would not allow an extrapolated conclusion about changes in smooth muscle activation. The degree to which smooth muscle will shorten when stimulated is influenced by the magnitude of the stimulus, the length of the muscle relative to optimal length, and the load that the muscle must overcome to shorten. There is evidence that smooth muscle in vivo does not contract isometrically or isotonically'3 but instead shortens under increasing tension provided by elastic afterloads. The elastic loads are related to the cartilage in the large airways and to the lung elastic recoil in the intraparenchymal bronchi and bronchioles. If there is a decrease in cartilage and/or lung elasticity, then the load on the contracting smooth muscle is less, and a given degree of muscle activation will produce more shortening and airway narrowing. Since a loss ofcartilage and lung elasticity are features of the development of COPD,4-5 this has direct relevance to the results reported by Gross and colleagues. As they in fact suggest, it is possible that the greater bronchodilatation in patients with more severe …


The major obstacle to shallow water acoustic communication is the interference of multipath signal results from surface and bottom reflections. Channel coding is indispensable in practical system to accommodate these adverse channel transmission characteristics due to the coding gain. In this paper, a channel model including time-varying fading, multipath and additive noise for the shallow water acoustic channels is built. Based on the channel model, the Probability Density Function (PDF) of initial decoding messages with Belief Propagation (BP) algorithm of Low-Density Parity-Check (LDPC) codes is deduced. The performance of the LDPC codes with BP algorithm is simulated, and the effects of multipath, fading velocity and channel interleaver on the decoding performance are studied. As the result, the following conclusions can be given: The performance of LDPC codes is excellent (Bit Error Rate (BER) is less than 10-4) over three-multipath shallow water acoustic channels, with 3-5 iterative decoding times and about 1000 bits code lengths; The BER of LDPC codes degrades with the increasing of the number of multipath; The BER of LDPC codes degrades slowly with the decreasing of the fading velocity, which shows the proposed channel code is not sensitive to the fading velocity of the channel.


OBJECTIVE
To study the expression of cyclooxygenase-2 (COX-2) in bladder transitional cell carcinoma (Tcc) and the clinical significance thereof.

METHODS
Immunohistochemistry was used to detect the expression of COX-2 in 56 specimens of bladder Tcc and 10 specimens of normal bladder tissue, all resected during operation.

RESULTS
No expression of COX-2 was detected in the 10 specimens of normal bladder tissue and in the 56 specimens of bladder Tcc the positive rate of COX-2 was 55.36%. The expression of COX-2 in bladder Tcc was closely correlated with the grade and stage of tumor (both P < 0.01).

CONCLUSION
COX-2 expression in bladder Tcc is closely correlated with the grade and stage.


ABSTRACT Like many other disciplines, the information systems (IS) community has embraced big data analytics and data science. However, in the rush to exploit the popularity of this latest trend, the areas of big data analytics and data science that are most relevant to the IS field are not made clear. While many consider data analytics as an evolution of decision support systems (DSS), that is, as a technology that needs to be managed or enhanced, this essay traces the complex origins and philosophy of analytics instead back to Luhn's text analytics in the late 1950s, Naur's Computing as a Human Activity and his datalogy, Tukey's Future of Data Analysis of the 1960s, and Codd's relational database schema in the 1970s, well before big data analytics and data science became industry buzzwords. Many of what is now considered mainstream thinking in big data analytics and data science can be traced back to these visionaries. This essay examines the implications of the complex origins of data analytics and data science for the IS field, specifically on how those different discourses impact future research and practice.


The skin is the organ that protects the human body. However, factors such as solar radiation damage the texture and skin cells. Sometimes, the lack of timely diagnosis leads to skin cancer. In this line, melanoma is the most dangerous type of cancer and has caused the greatest number of deaths related to skin diseases. With this problem, collaborative efforts between different research areas are necessary to support early detection of the disease. In this way, the evolution of algorithms based on neural networks plays an important role for image processing, which is an essential activity for pattern detection and recognition in medical diagnosis. Faced with this challenge, this research proposes a web prototype based on convolutional neural networks to support melanoma detection. In this context, the reference framework suggested by the Cross Industry Standard Process for Data Mining (CRISP-DM) was used. For this, 18,000 high-quality images were compiled from the data science community. In addition, two learning models (based on convolutional neural network and Res-Net50) were created and evaluated. With these premises, a web application was developed using the waterfall model. Finally, conclusions and future work are suggested at the end of the document.


There are many definitions and models of reflection on offer. Writing in this issue of Medical Education, Nguyen et al. report on the integration of several influential models from the existing literature to formulate a theory-based and unified definition with the aim of improving the practical application of reflection. They take a cognitive approach to the thinking processes underpinning reflection with the commendable aim of improving our understanding and the acceptability of the reflective process. However, combining multiple definitions does not guarantee a simple solution. The aphorism 'a camel is a horse designed by committee' comes to mind. If we were to consider all the definitions of a horse in different dictionaries, we would find a wide variety, some of which exclude certain elements. However, the exclusion of these elements does not inevitably mean that the animal defined is not a horse. Furthermore, incorporating all definitions into one definition will not automatically help the reader to understand the concept of a horse. Could the same be true of reflection? Might there be an unintended consequence of creating an even more formulaic approach to a process that is essentially individualist? The ultimate aim should surely be to make reflection a meaningful process, not a ritual. The learner should be empowered, not constrained.


This paper develops two algorithms for computing the average total cost per product and other performance measures for a make-to-order inventory-production system. The two algorithms are developed by using matrix analytic methods. The first algorithm is based on the matrix-geometric solution of the Quasi-Birth-and-Death (QBD) Markov process. The second algorithm is based on the fundamental period of the QBD Markov process. The advantages and disadvantages of the two algorithms are discussed


The whole diesel exhaust used in the studies evaluated here was generated from fuels and diesel engines produced before the year 2000. Exhaust from these engines include three basic components: elemental carbon particles in respirable clusters; organic matter adsorbed onto the surface of the carbon particles, which is readily extractable with organic solvents; and a mixture of gas and vapour phases that include volatile organic compounds. Many studies have been carried out using several animal species to evaluate the potential carcinogenicity of expo sure to whole exhaust and to the components of exhaust from diesel engines. The studies were considered under three subcategories: (i) whole diesel engine exhaust; (ii) gas-phase diesel engine exhaust (with particles removed); and (iii) diesel engine exhaust particles or extracts of diesel engine exhaust particles. Animal bioassays conducted with different diesel engine exhausts have been reviewed previ ously in the IARC Monographs (IARC, 1989). This section provides a summary of these and a detailed review of more recent studies.


The instrumental music classroom, commonly called "the band" is comprised of students from all parts of a school population. Some may think or assume that band students are inherently engaged. However, engagement strategies to reach all students need to be reviewed, revisited, and modified, even in the ensemble-based class. Action steps to engage more students more often should be employed in the music room, modified as necessary, which means it is important to know what engagement in a classroom really means. Engagement is a changing state of being and is affected by different variables.

In this paper, we analyze the performance of a photovoltaic array under shading faults. Actually, the solar power generation systems use the photovoltaic (PV) effect to transform solar energy into electrical energy. The performance of a (PV) array is affected by temperature, solar irradiance, shading, and array configuration. In this study and in order to optimize the performance of a PV system, it must at first, aim the recognition of faults that may affect the efficiency of the PV system. Furthermore, it proposes a global analysis of the I-V characteristic of the PV module. Subsequently the array curves measured were validated with a photovoltaic array model developed in MATLAB-Simulink, elaborated to study and validate the I-V characteristics of a PV module under a non uniform change due to especially the external solar irradiance. The model used for the simulations of normal and faulty conditions has been experimentally validated.


The concentration of leukocytes and the fraction of neutrophil granulocytes are two important criteria in the diagnosis of peritonitis in continuous ambulatory peritoneal dialysis (CAPD). We have found that leukocytes are unstable in dialysis effluents, resulting in false low leukocyte concentrations if not counted immediately. At 25°C the leukocyte count decreases 25%–30% in 4–6 hours. Sampling in tubes containing EDTA and storage at 4°C make the leukocyte concentration stable for 6 hours, while the combination of EDT A and storage at 4°C ensures stability for 24 hours. When samples are handled accordingly, concentrations as high as 2 × 108/L are observed without any clinical signs of peritonitis, especially within the first months of CAPD-treatment. Thus, we suggest a leukocyte-concentration of 2 × 1 08/L as the diagnostic limit for peritonitis. Concerning fraction of neutrophils a diagnostic limit of 0.50 still seems relevant.


This paper describes a qualitative study of two school districts' efforts to support school leaders in developing the knowledge and skills to analyze, understand, and transform system inequities. The results suggest that, despite being armed with knowledge and skills, leaders may be reluctant to act even when doing so is within the scope of their authority. This work draws from Fullan's (2003) concept of moral imperative and examines the connection between moral imperative and women's ways of leading. The findings have implications for educational leadership programs that seek to prepare school
leaders capable of challenging and changing inequitable systems.

Keywords: leadership, moral imperative, school reform, equity, women's leadership

In this essay, we shall try to arrive at a satisfactory interpretation of Kierke gaard's very complex view of the structure of selfhood by analyzing his arguments as expressed primarily in The Sickness Unto Death and The Concept of Dread. It will be maintained that Kierkegaard's conception of selfhood can be more adequately grasped by placing is his discussion within its historical context. As will become evident, the task of understanding this issue is complicated considerably by Kierkegaard's tendency to use different categories interchangeably, and by his persistent use of philosophical terms to which he gives meanings different from those traditionally associated with them.


Abstract The development of C(sp3)−H functionalization reactions that use common protecting groups and practical oxidants remains a significant challenge. Herein we report a monoprotected aminoethyl thioether (MPAThio) ligand‐enabled β‐C(sp3)−H lactamization of tosyl‐protected aliphatic amides using tert‐butyl hydrogen peroxide (TBHP) as the sole oxidant. This protocol features exceedingly mild reaction conditions, reliable scalability, and the use of practical oxidants and protecting groups. Further derivatization of the β‐lactam products enables the synthesis of a range of biologically important motifs including β‐amino acids, γ‐amino alcohols, and azetidines.

The series purpose is to broaden the current dialogue on leadership research to include pieces that share wisdom and inspire ideation, nurturing and assessment of the field. Senior scholars are invited to share their views and opinions which we will feature as Fireside Chat commentaries. Their intended value is to offer a widely-accessible conversation space to reflect, create, and share wisdom.


In this paper, we examine the attitudes towards gender roles among higher education students in a borderland Central-Eastern European region. We used the database of 'The Impact of Tertiary Education on Regional Development' project (N=602, 2010). We intend to determine what kind of attitudes towards gender roles the students identify themselves with, whataffects these attitudes (gender, faculty type, social background of students, locality type, religiosity), and finally what kind of educational policy implications could be relevant concerning our findings. We have used cluster analysis and a logistic regression model, and formulated several hypotheses that were controlled by these methods. Our results show that there are a large number of students who belong to the more traditional attitude cluster in this region, but women more frequently identify themselves with modern gender roles than men do. The faculty-type effect has only been partly detected. We have found that with 'male-dominated' majors, both women and men identify themselves with more traditional attitudes and that with 'female-dominated' majors all students have more modern  attitudes. The effect of social background is contradictory. Those whose parents had larger numbers of books had increased modern attitudes, but the factor 'regular financial problems in the family' also increased it. Our next result is that students who live in villages are not more traditional than others, because they live in cities during their studies. Our final result is that churchly religious students think more traditionally regarding gender roles than others do, but those who are religious in their own way do not.


The paper presents a data-based synthesis method for power control algorithm of a wind turbine in full-load operating region, within a general strategy of gain scheduling type. The proposed method is based on the existence of several efficient solutions for the generation of a detailed mathematical model for a high-power wind system that by its simulation in different operating regimes can provide the necessary data obtained for the design procedure. The synthesis of the control algorithm is based on the construction of a dynamic compensator which can quickly provide the parameters of a PI control law for the rotational speed loop. In the paper the effects of the drive train torsional vibrations in the controller synthesis are analyzed by numerical simulation. Some results obtained with the gain-scheduling control approach are also presented.


For the method based on discernibility matrix for computing a core,reducing the size of discernibility matrix is the key for improving the performance of computation of a core.Therefore,an algorithm(AMDMC) based on multi-discernibility matrix is introduced to computation of a core for the case of unbalanced classification data.By the decision attribute's value,the all objects are partitioned into some subsets.For any two different subsets,a sub-discernibility matrix is created.Finally,the multi-discernibility matrix is obtained and a core is acquired.Each sub-discernibility matrix holds a small space because of unbalanced classification data,so the AMDMC algorithm is in high efficiency.Theoretical analysis and experiment results show the effectiveness of the algorithm.

The aim of research of the tribological conditions in the tool-workpiece interface in high-speed machining is to find the main causes for unpredicted tool life. As is shown in the paper there are many causes for their influences on the tool wear. Not only mechanical and chemical but also thermochemical aspects of wear are found on the cutting edge. In high-speed cutting (HSC) of steel the temperature on the cutting edge is right near the critical level to cause the onset of diffusion type of wear. New generations of modern cutting materials (coated carbides, cermets, CBN) are gaining ground in modern production where cutting parameters of HSC technique are really high, thus resulting in specific tool wear behaviour.


Confession in the context of ecclesiastical polity with special reference to the concept Church Ordinance 1997, Nederduitsch Hervormde Kerk van Afrika. In essence the question under discussion is about the functioning of the confession in church polity and how it is phrased in the concept Church Ordinance (1997) of the Nederduitsch Hervormde Kerk van Afrika. This logically brings the very difficult question of doctrinal discipline up for discussion. The paper starts with a few remarks on the relation between scripture, confession and church polity. The tradition, forming the background of the concept, is traced from the time of the Reformation. After a short discussion on how doctrinal discipline was seen and put into practice in the Nederduitsch Hervormde Kerk van Afrika, final remarks are made on how this matter is handled in the concept.


A pulsed erbium glass laser operated at 1533 nm using transverse pumping by four 12-bar laser diode subarrays at 932 nm. The laser ran in free-running and Q-switched modes, using both electro-optical and mechanical switches. With a LiNbO3 Pockels cell Q-switch, the erbium laser achieved 57 mJ energy per pulse, 26 ns pulsewidth and 3 Hz repetition rate.


In this paper, we consider alternate ways of storing a sparse matrix and their effect on computational speed. They involve keeping both the indices and the non-zero elements in the sparse matrix in a single data structure. These schemes thus help reduce memory system misses that occur when the usual indexing based storage schemes are used to store sparse matrices and give promising performance improvements.


For many years individual cow cell counts has been measured at all control dates in Denmark. Due to limited use of the existing presentation of the measurements a new simpler system is now introduced with grouping cows as healthy or infected based on a cutoff value of 200.000 cells/ml independent on stage of lactation or lactation number. By this subdivision we were able to validate data from all 535.000 Danish cows in the herd control system in 2010 On average 23% of all heifers were infected at first control after calving. On average 30% of all cows were infected at each control day in 2010. Infection rate were reduced by 2% in 2010 compared with 2009. Infection rate were constantly lower in 2010 with a higher difference from august correlating a lower BTSCC and a lower mastitis incidence in Denmark. Average infection rate related highly to lactation number with 18% in 1st lactation 32% in 2nd lactation and 44% in older lactations. Changes between two test days within lactation were: Newinfection rate 10%,16% and 21% of cows with low cell counts, chronically infected 10%, 21% and 32% and cure rate were 44%, 31% and 22% of cows with high cell counts in respectively 1, 2 and older lactations In the dry period new infection rate were 30% and 37% of cows with low cell counts, chronically infected were 11% and 25% and cure rate were 56% and 50% of cows with high cell counts in respectively 1 and older dry periods. In all 282.162 dry periods received no therapy whereas 51.834 received dry cow therapy. Infection at first control day after calving were 40% and 31% for respectively no therapy and antibiotic therapy at dry off with a cure rate of 47% and 63% during the dry period. The presentation will focus on variation in the different udder health indicators in relation to dry cow treatment and variation between herds


Inference of functional language networks from functional Magnetic Resonant Imaging and network theory by Qiongge Li Adviser: Professor Hernan Makse We study the underlying mechanism by which language processing occurs in the human brain using inference methods on functional magnetic resonance imaging data. The data analyzed stems from several cohorts of subjects; a monolingual group, a bilingual group, a healthy control group and one diseased case. We applied a complex statistical inference pipeline to determine the network structure of brain components involved with language. This healthy network reveals a fully connected triangular relationship between the preSupplementary Motor Area (pre-SMA), the Broca's Area (BA), and the ventral Pre-Motor Area (PreMA) in the left hemisphere. This "triangle" shows consistently in all the healthy subjects (100%) we analyzed regardless of their monoor multi-lingual status. In addition, we found that Wernicke's Area (WA) on the left hemisphere connects with BA and PreMA to form a "V" shape connectivity across 75% of the monolinguals, 50% of the bilinguals speaking a second language and 100% of the bilinguals speaking their native language. By comparing the quantified link weights, we found that the strongest link is between BA and PreMA, followed by pre-SMA and PreMA, and then pre-SMA and BA. This is consistent for all healthy subjects (p < 0.05). Furthermore, we conducted a k-core analysis testing the resiliency of subnetworks in the three groups. Our results show that nodes in the three triangle areas belong mostly to the maximum shell, whereas WA populates mostly in the lower shell, consistently across the data.


Summary StatementFor RA patients undergoing TKR, the gain in function at 6 months following surgery is less than that experienced by OA patients; for THR, however, gains are similar in OA and RA patients.IntroductionTotal joint replacement (TJR) is commonly used in rheumatoid arthritis (RA) patients and yet little information is available to quantify their functional gain following surgery and how it differs from what the osteoarthritis (OA) population experiences. Therefore, we examined 6-month functional outcomes of TJR in a population-based observational cohort of RA and OA patients who underwent total hip (THR) or knee (TKR) replacement.MethodsPatients undergoing primary TKR from 7/1/11 through 12/3/12 were identified from the FORCE-TJR national research consortium which enrolls patients from 111 surgeons across 27 states in the US. The registry gathers data from patients, surgeons and hospitals on patient demographics, underlying type of arthritis, operative joint severity based on the estimated West...


This paper reports on the preparation, electrical, and optical analysis of electrodes and prototype electrochromic devices using a solid polymer ion conductor. For these devices electrodes were developed consisting of cobalt-doped nickel oxide, manganese-nickel oxide, and niobium oxide. Optical and voltammetric data was obtained for each electrode. Solid polymer electrolytes were synthesized from modified amorphous poly(ethylene oxide) [a-PEO] complexed with a metal silicate. Electrochromic devices were made using cobalt-doped nickel oxide/niobium oxide, and cobalt-doped nickel oxide/manganese-nickel electrode laminations. Optical spectra as a function of voltage was obtained for each device. The best cobalt-doped nickel oxide/a-PEO/manganese-nickel oxide device showed photopic transmittance to be Tp(bleached) equals 0.76 and Tp(colored) equals 0.44. The corresponding integrated solar transmittance was Ts(bleached) equals 0.64, Ts(colored) equals 0.46. The best cobalt- doped nickel oxide/a-PEO/niobium oxide device had photopic transmittance of Tp(bleached) equals 0.65 and Tp(colored) equals 0.16. The corresponding integrated solar transmittance was Ts(bleached) equals 0.45 and Ts(colored) equals 0.15. Of the two devices, the nickel/niobium oxide device had the best combination of electrical and optical properties. Better device properties are expected with improvements in the solid polymer electrolyte and lamination process.

In this paper, chromosomal karyotype of Wushen horse in Inner Mongolia was studied by using the peripheral blood lymphocytes culture method and conventional chromosome analysis techniques. The results showed that the diploid chromosome number of Wushen horse was 2n=64. The chromosome karyotypes of male and female horse were 64,XY and 64,XX. Among 31 pairs of autosomes, of which 13 pairs were met centric or submetacentric and 18 pairs acrocentric chromosomes, X chromosome was larger submetacentric chromosome and Y was the smallest acrocentric chromosome. Karyotypes of Wushen horse may lay a foundation of insitu hybridization and location of gene.


On August 14th 1996, the opening ceremony of the Amsterdam ArenA took place; the first stadium intended to be a multifunctional structure, a place where to host a wide variety of events, with a highway passing underneath the pitch and with a sliding roof. The Amsterdam ArenA case represents a successful example of private-public partnership. A win-win solution has brought benefits to both parties. In today's competitive global markets, the event itself is no longer sufficient to motivate consumers to pay expensive tickets and parking fees. To be worthwhile, spectators expect to be immersed in an experience. AFC Ajax remains the stadium's anchor tenant, Nevertheless the Amsterdam ArenA case also demonstrates the role that a stadium can play as a catalyst for urban renewal.


F. Bono et al. INTRODUCTION The visual stimulation with a target moving in step-like fashion from a central fixation point to an horizontal eccentric position, evokes a voluntary saccadic movement in a subject asked to follow the target. Multiple stimulations, at different right and left eccentricities, produce a record with a set of different saccades on the same trace. The recognition of the saccadic movement is required to perform a saccade analysis and must be carried out extracting the saccade from the global eye movement signal. Generally this is accomplished identifying the saccade beginning and ending instants along the velocity signal, through the aid of a velocity threshold. The portion of trace above threshold is taken as the "saccade signal source" and is used for computing all the saccade related parameters. This implies that all the analysis is performed on an incomplete signal, if a velocity threshold greater than zero is chosen. The main advantage of this process is to skip the noisy baseline which is typical of the velocity trace. On the other hand, a well known and relevant disadvantage is to get an unreal variation in some measured parameter: latency, duration, mean velocity and K-factor may be, for example, highly influenced. The noisy signal can be more evident in EOG records taken from children, due to the restlessness of their traces and in this case the signal to noise ratio is further worsened for saccades of small eccentricities (i.e. below 5°). Values such as 10, 30 and 40 degrees⋅sec-1 are normally attributed to the velocity threshold and after its direct application to the velocity signal, the saccadic velocity profiles are automatically detected. Lower threshold values cause an increasing number of false saccade identifications: if a zero threshold is used, a mess of apparent saccades is detected, due to the noisy baseline. The direct application of the zero-threshold, which should be the most suitable and realistic to use, is therefore possibly confusing. In order to explore the effective influence of the threshold value on parameters of the saccadic movements recorded in children, we developed a simple algorithm which applies the "zero crossing" criterion to saccade velocity profiles, for stimulus eccentricity ranging from 3° to 20°. In this way we have been able to compare the parameter behavior applying three velocity threshold values: 0, 10, 30 degrees⋅sec-1. Moreover, we performed a rough meta-analysis on data published by various authors (Baloh …

Objective To investigate the effect of SP600125 on insulin resistance induced by TNF-α.Methods The insulin resistance cell model were induced by TNF-α(4 ng/mL)to stimulate human hepatoma carcinoma cell HepG2.The intracellular glycogen was detected using a glucose oxidase assay kit.The expression of JNK and p-JNK were observed by Western blot.Results Compared with control,TNF-αtreatment decreased the level of intracellular glycogen in HepG2 cells.However,SP600125 treatment reversed the effect of TNF-α.JNK was activated in response to TNF-α and that effect was reversed by SP600125.Conclusion SP600125 may improve the insulin resistance condition of HepG2 induced by TNF-α.


Let 5 be a commutative cancellative semigroup of finite rank (the free rank of the quotient group of S is finite). We give a necessary and sufficient condition for S to have a nontrivial homomorphism into the additive semigroup of nonnegative (positive) reals. We also give a counterexample in the case of infinite rank.


The need for change in the design of learning spaces demands radical rethinking of many powerful traditional assumptions, yet this activity is vital to the success of higher education in the future.


The contribution of the public procurement sector to the economic and social development and the efficient use of public resources makes it a strategic tool for public policy. This bachelor studies the national policy in this field, in two distinct periods, namely before and after the revision of the relevant legislative framework, which was completed with the publication of Law 4412/2016. In particular, it presents the previous legislative framework and analyzes the main pathogens that emerged during its implementation. Furthermore, the major reforms that have been made in the field of public procurement, with a review of the legislative framework, which illustrate the relevant national options, are outlined in detail. Finally, a first assessment of the implementation of the new legislative framework for the award and performance public procurement of goods, services and works is taking place.
Sources of work were, in particular, the provisions of Law 4412/2016 and Directive 2014/24/EU and their recitals, studies of international organizations and European institutions, Greek and foreign websites, with an emphasis on web sites of the European Union and its institutions, which deal, primarily or in part, with public procurement law. Additionally, Greek and foreign literature, as well as articles, were studied.


Based on the joint Gaussian distribution of optical signal log-amplitude sequence,an algorithm for Maximum a posteriori probability(MAP) detection was proposed to mitigate effects of atmospheric scintillation on the performance of the free-space optical communication.And the bit error rate for the proposed algorithm was simulated.Simulation results show that the proposed algorithm for MAP detection based on the joint Gaussian distribution mitigates effects of atmospheric scintillation on the communication performance and leads to a furthest improvement in detection performance,compared with maximum-likelihood symbol-by-symbol detection and MAP symbol-by-symbol detection.


The differences of two determination methods, including acetylacetone requirements, protraction of standard curve, wavelength choice and samples pretreatment, were elaborated for determination of free formaldehyde content by acetylacetone spectrophotometry in GB 18 582-2001 and GB 18 583-2001. After difference cause between two testing results was particular analysed, the two standard methods were improved and a fit determi- nation method of free formaldehyde content in water-soluble coatings and adhesives was presented. The linear range of formaldehyde content was 1-25 μg and the correlative coefficient was 0.999 9. According to the improved determination method, the relative standard deviations of determination results for free formaldehyde content in water-soluble coating and adhesive were 1.9% and 2.3%, and average recovery rates were 94.2% and 95.8%, respectively.


Upon almost identical conditions of application, the GDPR takes precedence over national legal regime for merchandising. It raises the research question: how would the GDPR regulate merchandising? And, whether the consequences are theoretically justified and practically reasonable? Unlike the GDPR, which is devised to enhance one's control over personal data by omitting its commercial value and limiting personal autonomy in private law, the German legal regime recognizes the pecuniary components in the right to one's image and de facto confirms their licensability. The KUG offers over 100 years of experience in merchandising for the GDPR's risk-based approach.


Informal learning has become an important driver for professional development and workplace learning. Yet, however powerful informal learning may be, there is a problem when it comes to making it a real asset within organizations: Informal learning activities are spontaneous and mostly invisible to others. The aim of this study is to develop a method that helps raise awareness about these activities using a learning analytics approach. This method concentrates on detecting and visualizing informal professional social networks and finding ways in which their presence and accessibility can be improved. This study shows that the presented methodology is a promising research-driven intervention. With this methodology we can detect multiple (isolated) networks in organizations, connect ideas, and facilitate value creation. Using this approach, organizations can link with existing informal networks of practice and unlock their potential for organizational learning by giving them a voice and making their results more explicit within the organization.


The possibility of the highly effective stable compression of electron bunches by fields of different symmetry in O-type devices by means of optimum profiling of the wave phase velocity and focusing of the magnetic field both in the bunch acceleration and deceleration modes is shown. The described modes of the electron bunch compression can be applied to develop the effective methods and devices of the frequency multiplication.


There is increasing commercial and environmental interest in the use of microbe- based agents as alternatives to, or in combination with, chemicals for controlling the spread and severity of a range of crop diseases. The identification of specific microbial metabolites that are able to control certain plant diseases has led to the development of strategies for improving the performance and predictability of the microbial strains that produce these metabolites for application in the agricultural industry. This article focuses on antimicrobial metabolites produced by fluorescent pseudomonads, discusses their role in suppressing fungal diseases of important crops and reviews the prospects of genetically manipulating the producer organisms to improve the efficacy of these biocontrol agents.


This article reports a content analysis of advertisements for household goods appearing in Ladies Home Journal between 1909-1910 and 1980, with the aim of understanding the ideological campaign that characterized the years in which households were mechanized and women's domestic labor transformed in the United States. More Journal ads featured directives about housework than descriptions of the product; they emphasized work performance far more frequently than liberation from housework, and they also promoted service to family. These findings supplement other evidence that advertisers' efforts to create a market for household appliances and other means of domestic labor involved promotion of an ideology about housework that reinforced women's dedication to it.


A general theory of periodic electrostatic focusing structures in micowave tubes is presented. A general method for evaluating the properties of focusing systems is developed. The method is based on the use of the Action Function and is applicable to structures whose potential distribution can be found by the method of separable variables. It is shown that this approach can yield results similar to, but more exact, than those obtained by the classical paraxial ray equation. The basic and double-ring structures have been examined in detail. Parameters describing these structures are presented in graphical and tabular form. It is shown that for irrotational flow, a specific current distribution is required. The use of computer techniques for the solution of electron flow problems is discussed. A computer analysis has been developed and results obtained are discussed. The accuracy of the Action Function and the computer analyses has been verified experimentally. It has been shown that the focusing potentials predicted by the Action Function analysis are in good agreement with the experimental values. The computer analysis has also been shown to give results comparable with those obtained practically. Hollow beams of 3.85, 5.4, and 15.6 µP have been focused using the basic ring structure. In order to investigate the effect of unbalance of focusing and defocusing forces at the inner beam boundary, pinhole measurements have been made. It is shown that the ring structure focuses a hollow beam with some change in the beam cross section. The effect of the unbalance of forces is to transform the current density profile. Results indicate that the transformation is desirable since a beam of constant current density may be transformed to a distribution which approaches that required for irrotational flow.


Environmental issues are playing a pivotal role in the ongoing operations in the Balkan states. U.S. Army commanders have realized that environmental issues have strategic and operational implications. Each of the Balkan countries where the Army has had missions is of unique character and state of development. The Army is developing a doctrine in facilities support and environmental protection that enables the Army to achieve all mission objectives. The Army serves as a role model of how a military force should operate, from an environmental protection standpoint, in a free society. Environmental protection is now seen by the command as a mission enabler and as a force protection issue. The evolution in command thinking from the start of the mission in Bosnia to the inception of the mission in Kosovo is dramatic. The recognition by the command of the relationship between environmental issues and mission accomplishment grows with each deployment of forces. © 2001 John Wiley & Sons, Inc.


Highlights the growing impact of product liability on retailers, manufacturers, suppliers and consumers in the brewing industry. Amongst the major findings of the study are: the UK brewing industry tends to view product liability in the same way as health and safety, conform to the standards and everything will be okay – this approach considers the criminal aspects of liability but blindly ignores the dangers of increased civil activity against them; product liability problems with beer stem mainly from the packaging process where objects may have got into the bottle/can, and tampering is on the increase in the industry. Points out that brewers can protect themselves against product liability claims by ensuring technical evaluation is available on all delivered products; ISO 9000 series registration; ensuring that all products retailed are properly labelled; setting up a recall pressure plan and practising it; establishing a crisis management team and identifying the logistical support required.


In this paper, a transformer-less solar PV inverter system which integrates a solar panel, battery, dc link, dc load and the AC power grid is proposed. A 300W resistive load is connected to the dc rail and the share of power that is supplied from different power sources, to keep the dc rail voltage constant, is decided by fuzzy logic control. The amount of power from the solar panel is controlled by a boost converter to operate in on/off MPPT modes as prompted by the controller. A bidirectional dc-dc converter is used to control the flow of power between the battery and the dc rail whereas an H-bridge inverter is provided for the bi-directional flow of power between the grid and the dc rail. The transformer-less topology helps to reduce the size and weight of the system. The operation of the system is verified using MATLAB-SIMULINK simulation.


The present invention relates to means for monitoring pre-fire situations arising as a result of the local overheating of electrical equipment and is intended for preventing fires caused by electrical wiring faults, particularly faults in wiring devices. The claimed system consists of: a gas sensor, connected to a monitor, which is connected to a system for delivering a signal; and a cross-linked polymeric composite material, which is applied to the portions of an electrical circuit that are susceptible to heating, said material having a rupture temperature in a range of 80-200°С and containing a low-boiling substance that is easily detected by the above-mentioned gas sensor. The technical result of the claimed invention is an increase in the likelihood of early detection of a pre-fire situation.


A broad concept of medical education is essential in the present era. For the purposes of my discussion, I have taken medical education to include the basic and postgraduate training of the major professional groups concerned with the health care of the people. The medical school is recognized as the indispensable, integrating force of the medical center of the future. The medical center, as we visualize it, would be the hub of continuous research and education, as well as of medical and public health services to outlying areas. The contemporary problems of medical education are matters of public concern. In 1946 Dr. H. G. Weiskotten stated: 1 The first and most important step to be taken in improving the health and medical care of the American public is to see to it that medical schools are provided with sufficient funds to conduct a basically satisfactory program of medical education. Since


PbZr0.53Ti0.47 (PZT)/BaPbO3(BPO) heterostructure was fabricated by combining the sol-gel and RF-magnetron sputtering techniques. The BPO bottom electrode can effectively prevent the formation of the rosette structure of PZT and reduce the crystallization temperature to 550°C which is 100°C lower than that needed in PZT/Pt film. The BPO bottom electrode not only improves the fatigue property but also reduces the leakage current density. Thus, the BPO electrode can be a good candidate for use in PZT ferroelectric capacitor.


Denis Doherty, Chairman of the Irish Hospice Foundation, has called for a compulsory review to follow all deaths in Ireland.


The Boeing/AFOSR Mach-6 Quiet Tunnel has achieved quiet flow to stagnation pressures of 146 psia, and intermittently quiet flow between 146 and 169 psia. In an attempt to measure natural transition under quiet flow, a 3-m-circular-arc compression cone was tested with a nearly sharp nosetip. Using temperature-sensitive paint, hot streaks were observed to develop near the rear of the cone at high pressures under quiet flow. The streaks do not appear under noisy flow. The cause of the hot streaks remains unknown, though they may be instabilities or artifacts of nonlinear breakdown. Under quiet flow, the cone boundary layer remained laminar up to N factors of at least 15 and possibly as high as 19. Transition occurred at N = 9 under noisy flow. It is unknown why laminar flow persisted to such high N factors. As part of an investigation of crossflow vortices, a 7 half-angle cone was tested at 6 angle of attack with temperature-sensitive paint finishes of varying roughness. The roughness of the paint finish was observed to have an effect on crossflow vortices, in some cases inducing transition under noisy flow. Heat-transfer measurements were made at the stagnation point of a hemisphere to observe the effect of freestream noise; no effect was evident.


A numerical approach to studying thermally induced optical nonlinearity semiconductors is presented. A transient difference algorithm is applied to thermal diffusion equation coupled nonlinear absorbance-transmittance of Au/GaSe/Au samples with an applied electric field. The presented analysis can deal with any arbitrary axisymmetric dependence of the input power over the sample and external electric field, and provides information about the steady state and transitory effects in the transmittance.


Hydrogenolysis of aryl tosylates with hydrazine in presence of palladium catalyst involves a preliminary decomposition of hydrazine to give inter alia hydrogen, which then accomplishes the hydrogenolysis. The reaction can be carried out with molecular hydrogen in the presence of the same catalyst but not under reaction conditions involving the intervention of di-imide as the reactive species. Mono-nuclear aryl tosylates cannot be successfully hydrogenolysed with hydrazine over palladium. A novel method was established of generating di-imide from hydrazine and iodine in presence of base or excess hydrazine.


We report on a 26-year-old female patient presenting all the classical symptoms of TAR syndrome: absent radii, unilateral humeral hypoplasia, normal thumbs. - thrombocytopenia; - short stature. The intelligence was normal. The chromosomal analysis revealed a 46 XX caryotype with breakages (+/- gaps or isogaps) or PCS in 77% of mitoses. To our knowledge this is the first case of TAR syndrome with chromosomal fragility. The common background of TAR S, Roberts/SC phocomelia S and Fanconi pancytopenia S is discussed.


A Question of Design sets out to explore and debate the role of the graphic designer as environmental issues become more urgent


Sheila Fitzpatrick has provided a useful history of our field in recent times, and she has done so in a gracious and personally revealing way. She is perhaps the most prolific and influential member of the field, and her observations cannot help but be tasty food for thought, especially as they come to us without the bitterness and defensive spite to which she might be entitled. Here I would like to reflect on some of the reasons why I think the controversy became so angry, why it went beyond the bounds of normal academic dispute. And bitter it was. In addition to vilification in print, our universities received unsolicited tenure letters suggesting that we were incompetent and dangerous. Editors published angry unsolicited book reviews submitted by our critics. One editor continued to solicit readers' reports on an article I submitted until he finally got a negative one. With five reports, four to one in favor of publishing, he nevertheless rejected the piece. Sometimes you just cannot win.


mandibular samples of red deer were collected at random in the Wandashan Mountains, eastern Heilongjiang Province during 1991~1994. By using Robinttes method of lower molar measurement, we measured 72 of all samples (Age≥2 5 years) and put forwards a fomula of molar ratio (MR) as follows: MR=Σ3i=1w i/Σ3i=1h i. Where, w i=the average width of occlusal surfaces of lower molar i;h i=the average heights above gum line of the corresponding lingual crests of lower molar i. By means of comparisons and statistics between MR and age of deer by determining of dental cement annuli method, The molar ratio MR as a quatitative index to determining ages or age classes of red deer was given .


This paper describes a SLAM II- FORTRAN simulation model of Drum- buffer-rope (DBR) as a production planning and control methodology at the engine component division of a Naval Aviation Depot. The model represents all of the functional areas of remanufacturing facility (a total of 27 shops) required for the repair/overhaul of an aviation component, as well as DBR for production planning and control. The model allows for experimentation in a variety of areas, including setting buffer sizes, buffer management techniques, input/output control, and capacity management. The model experiments indicate that DBR is an extremely robust method of production planning and control and that DBR leads to better performance to schedule, lower work-in- process inventory and improved use of present resources.


The debate over whether we should believe that mathematical objects exist quickly leads to the question of how to determine what we should believe to exist. Indispensabilists claim that we should believe in the exist- ence of mathematical objects because of their ineliminable roles in scientific theory. Eleatics argue that only ob- jects with causal properties exist. Mark Colyvan's recent defenses of Quine's indispensability argument present an intriguing attempt to provide reasons to favor the indispensabilist's criterion against some contemporary eleatics. I show that Colyvan's argument is not decisive against the eleatic and then sketch a way to capture some of the important intuitions behind both views.


The utility model relates to a double shell wall full flowing inner jacket type PVC polymerization kettle which mainly comprises a jacket sealing head, a jacket sealing head inlet, an inner cooling semitube jacket inlet, an outer shell barrel body of the polymerization kettle, an inner shell barrel body, an upper sealing head, a pressure balancing connection tube, an inner cooling semitube jacket outlet, an annular partition board, a jacket sealing head outlet and a lower sealing head, wherein the outer shell barrel body is provided with a pressurized element. The inner shell barrel body is a heat exchanging element, and the upper part of the inner shell barrel body is welded with the upper sealing head together. The lower end is welded with the outer shell barrel body of the polymerization kettle into a whole by the annular partition board. The pressure balance connection tube on the upper sealing head ensures the pressure balance at the outer side in the inner shell barrel body. The inner cooling semitube jacket is welded on an outer wall of the inner shell barrel body, one side of a semitube is welded on the outer wall of the inner shell barrel body and the other side is welded on one previous layer semitube to form a full flowing structure. The jacket sealing head is welded at the outer side of a lower sealing head, and cooling water respectively passes through the inner cooling semitube jacket and the jacket sealing head and cools the inner shell barrel body and the lower sealing head. The pressure at the outer side in the inner shell barrel body is balanced; wall thickness can be correspondingly lowered; heat transfer and hot resistance are reduced; the heat removing capability of a PVC polymerization kettle is enhanced.

Namoo is a narrative poem come to life as an animated VR experience that follows the journey of a man from his birth until death. Namoo was created entirely in VR with Oculus Quill and pushes the boundaries of what is possible in this new artform and platform for animation.


Oxbow says: In the early 8th century BC a Greek colony was established by the Parians on the island of Hvar in the Adriatic Sea, off the coast of modern Croatia. This volume presents a synthesis of what is known of this Greek colony gleaned from archaeological, written, epigraphic and numismatic sources. Branko Kirigin provides a review of the remains of Pharos and of research carried out on the city, before turning to what can be determined of its social organisation and administration, its economy, coinage, pottery, its cults and burial rituals, and the life of its most famous hero Demetrius of Pharos and his battle with the Roman consul Aemilius Paulus in 219BC which led to the destruction of the city.


A medium- and high-resolution spectroscopic survey of helium-rich hot subdwarfs is being carried out using the Southern African Large Telescope (SALT). Objectives include the discovery of exotic hot subdwarfs and of sequences connecting chemically-peculiar subdwarfs of different types. The first phase consists of medium-resolution spectroscopy of over 100 stars selected from low-resolution surveys. This paper describes the selection criteria, and the observing, classification and analysis methods. It presents 107 spectral classifications on the MK-like Drilling system and 106 coarse analyses ($T_{\rm eff}, \log g, \log y$) based on a hybrid grid of zero-metal non-LTE and line-blanketed LTE model atmospheres. For 75 stars, atmospheric parameters have been derived for the first time. The sample may be divided into 6 distinct groups including the classical `helium-rich' sdO stars with spectral types (Sp) sdO6.5 - sdB1 (74) comprising carbon-rich (35) and carbon-weak (39) stars, very hot He-sdO's with Sp $\lesssim$ sdO6 (13), extreme helium stars with luminosity class $\lesssim 5$ (5), intermediate helium-rich subdwarfs with helium class 25 -- 35 (8), and intermediate helium-rich subdwarfs with helium class $10 - 25$ (6). The last covers a narrow spectral range (sdB0 -- sdB1) including two known and four candidate heavy-metal subdwarfs. Within other groups are several stars of individual interest, including an extremely metal-poor helium star, candidate double-helium subdwarf binaries, and a candidate low-gravity He-sdO star.


Using Transition-State Theory, experimental rate constants, determined over a range of temperatures, for reactions of vitamin E type antioxidants are analysed in terms of their enthalpies and entropies of activation. It is further shown that computational methods may be employed to calculate enthalpies and entropies, and hence Gibbs Free Energies, for the overall reactions. Within the Linear Free Energy Relationship (LFER) assumption, that the Gibbs Free Energy of activation is propor- tional to the overall Gibbs Free Energy change for the reaction, it is possible to rationalise, and even to predict, the relative contributions of enthalpy and entropy for reactions of interest, involving potential antioxidants.


This paper has presented a method of size reduction of the CRLH transmission line antenna by using a magneto-dielectric material. The CRLH-TL antenna is composed of two patches and vias, and the magneto-dielectric material is constructed by split ring resonators. The resonant frequency of the antenna is reduced by using the magneto-dielectric material: 7.34% at -1st-order mode and 24.88% at zeroth-order mode. An antenna operated at zeroth-order resonant mode is fabricated and measured. It operates at 1.888 GHz and has a bandwidth of 0.48%, a gain of 0.534 dBi, and an efficiency of 51.7%.


The condition known as actinic lichen planus is believed to be a particular variant of lichen planus which occurs on light‐exposed areas. Synonyms include lichen planus tropicus,1 lichen planus subtropicus,2 lichen planus in subtropical countries,3 lichenoid melanodermatitis,4 and lichen planus atrophicus annularis,5 The majority of reported cases are from the Middle East,1–3,6 although there have also been cases in North Africans,7 black South Africans8 Kenyans,4 and Indians.9 There are other reports from Italy,10 the United States5,11 and the Netherlands.12 'Summertime actinic lichenoid eruption'has been suggested as a better term for the condition.


Intensification of fish culture systems can raise s tr ss levels of fish and lead to depression of the organic defense mechanisms and increase susceptibil ity of fish to pathogenic agents. The nutritional status of farmed fish drives the cellul ar responses to environmental disturbances. Hematological analysis is an important tool to diag nose the inset of diseases, and leukocytes play important roles in the non-specific immunity. Value s of leukocytes count are good indicators of fish health status. This work aimed at evaluating t he influence of the substitution of dietary soybean oil by sunflower oil on the hematological p erformance of pacu Piaractus mesopotamicus. Juvenile pacu (14.4 ± 0.4 g) were stocked in 70-L aquaria (15 fish per aquarium) under partial, continuous, individual wat er renewal system, continuous aeration (dissolved oxygen 5.02 ± 0.87 mg L ), controlled temperature (26.3 ± 1.4 C) and photoperiod (12 L: 12 D), and fed for 85 days with diets contai ing increasing levels sunflower oil (20, 40, 60, 80, 100%) in substitution of soybean oil, a con tr l diet (no sunflower oil) and a commercial feed, in a totally randomized design trial (n=4). B lood samples were drawn at midterm and final experimental period and differences in white blood cells count – total leukocytes, lymphocytes, monocytes, neutrophils and eosinophyls – were deter min d. Data were submitted to ANOVA and Dunnet ́s test to determine contrasts between tr atments and control means. Increased levels of sunflower oil elicited increased proliferation o f leukocytes, specially the lymphocytes (P<0.05).


Twenty young adult male rats were divided into two groups of ten rats each and fed either a powder or pellet diet of identical content for a thirty day experimental period. One hour prior to sacrifice, each rat was given an intraperitoneal injection of 0.5uc of tritiated thymidine per gram of body weight. After sacrifice, the maxillae were dissected out and prepared for autoradiographic and histologic study.

Proliferative cellular activity was determined in the periodontal tissues of the maxillary first molars. Significantly higher activity was noted in the crestal epithelium and in the fibroblasts at the interradicular septum of the pellet fed rats when compared to powder fed animals. These elevated values may reflect tissue responses to the coarser consistency of the pellets.

The second half of the 20th and the beginning of the 21st centuries saw massive transformations in differentdomains of public life which significantly affected families as well. Sociological studies have discoveredbehavioral norms behind relationships in families and marriages being washed out, transformation in familyroles, development of new norms and principles which come as a basis for matrimonial, parent-child andintergenerational relationships. The modern society experienced a critical shift in gender roles or parents. Therole of a father and a male is losing its value. Some of the reasons are that in case of divorce in Russia childrenmost usually stay with mothers.Russian parents inherit family practices from their own parents and modify them in accordance with their ownexperience and feeling what would be most beneficial for their children. Parenting styles in Russia are based onRussian mentality, way of life, traditions and current environmental situation and thus may differ from theparenting patters of other countries.To analyze transformations in parenthood and parenting in a modern Russianfamily the paper refers to a study "Parenthood, upbringing and childhood in a modern Russian family"(Novgorod, 2013).


The best known estimate for the packing of points into the 6-dimensional unit cube in mutual distances at least 1 is improved.


A low-cost single-layer 2-bit programmable metasurface (PM) is proposed in this article. This PM is processed on a single-layer printed circuit board (PCB) with the microwave structure, ground, and bias lines, enabled by a folded ground. The folded ground design moves a part of the ground from the bottom to the top layer to leave an area for bias lines. Vias are used to connect the ground in top and bottom layers to form a whole. The bias line in the microwave structure area is grounded by two capacitances to isolate microwave current with the bias line area. An asymmetric patch is designed in microwave area as the 2-bit microwave structure. To verify the microwave performance of this PM, functions of generating double beams, electromagnetic (EM) waves with orbital angular momentum (OAM), and a high gain beam are simulated. The far-field pattern of a $16\times16$ PM antenna in beam scanning is measured. The measured results show that the PM antenna has a beam scanning capability of ±60° and a maximum aperture efficiency of 44.6%. Finally, to illustrate the universality of the folded ground design, the varactor-loaded continuous phase adjustable PM and variable polarization 1-bit PM are discussed.


This paper addresses the problem of separating a cyclostationary source from linear mixtures. It first shows that if the cyclic frequencies of the source of interest are known and different from those of the interfering sources, perfect source separation can be achieved using the proposed separation criterion. Then an algorithm is derived to perform the blind source separation. Simulation results demonstrate the validity of the proposed algorithm


In this paper, an image analysis framework is formulated for Landsat-8 Operational Land Imager and Thermal Infrared Sensor (OLI/TIRS) scenes using the R programming language. The libraries of R are shown to be effective in remote sensing data processing tasks, such as classification using k-means clustering and computing the Normalized Difference Vegetation Index (NDVI). The data are processed using an integration of the RStoolbox, terra, raster, rgdal and auxiliary packages of R. The proposed approach to image processing using R is designed to exploit the parameters of image bands as cues to detect land cover types and vegetation parameters corresponding to the spectral reflectance of the objects represented on the Earth's surface. Our method is effective at processing the time series of the images taken at various periods to monitor the landscape dynamics in the middle part of the Congo River basin, Democratic Republic of the Congo (DRC). Whereas previous approaches primarily used Geographic Information System (GIS) software, we proposed to explicitly use the scripting methods for satellite image analysis by applying the extended functionality of R. The application of scripts for geospatial data is an effective and robust method compared with the traditional approaches due to its high automation and machine-based graphical processing. The algorithms of the R libraries are adjusted to spatial operations, such as projections and transformations, object topology, classification and map algebra. The data include Landsat-8 OLI-TIRS covering the three regions along the Congo river, Bumba, Basoko and Kisangani, for the years 2013, 2015 and 2022. We also validate the performance of graphical data handling for cartographic visualization using R libraries for visualising changes in land cover types by k-means clustering and calculation of the NDVI for vegetation analysis.


The cytochrom P450 (CYP) 2D6 enzyme is involved in the oxidative metabolism of many different classes of commonly used drugs, including antidepressants. The enzyme is highly genetically polymorphic, which results in metabolic capacity ranges between individuals from extremely slow, the poor metabolizer (PM), to extensive metabolizer (EM), or to ultrafast, the ultrarapid metabolizer (UM). CYP 2D6 deficiency can be a risk factor for adverse drug effects and increased toxicity in poor metabolizers when such patients are treated with standard doses of antidepressants. We report two cases of poisonings with the antidepressants amitriptyline and trimipramine in different CYP 2D6 genotypes. For the trimipramine poisoning in a CYP2D6*4/*5 genotye PM the calculated half-life was 3-5 fold higher compared to a poisoning in EM with amitriptyline. In both cases the plasma concentrations of tricyclic antidepressants were in the lethal ranges. The uridine diphosphate (UDP)-glucuronosyltransferases (UGTs) are key enzymes in human phase detoxification of drugs, which are generally transformed into water-soluble glucuronides. Gilbert syndrom is characterized by a mild hyperbilirubinemia and caused by an insertional mutation of a TATAA element in the UGT1A1 gene causing a reduced enzyme activity. In a young girl poisoned with diazepam and suffering of Gilbert syndrome we observed markedly prolonged half-lives for the parent compound and the metabolites, especially oxazepam. If the changed pharmacokinetic data are in the context of this gene defect remains unclear.


In this interview with Thomas Dekeyser, Eugene Thacker elaborates on the central themes of his work. Addressing themes including extinction, futility, human universalism, network euphoria, political indecision and scientific nihilism, the interview positions Thacker's work within the contemporary theoretical conjuncture, specifically through its relation to genres of thought his work is often grouped with or cast against: vitalism, speculative realism and accelerationism. More broadly, however, the interview offers a unique insight into Thacker's approach to the thinking, doing and writing of 'philosophy'.


Tea (Camellia sinensis (L.) O. Kuntze) is a globally important crop and is unusual because it both requires and acidifies the soil in which it grows. In spite of the low pH, high nitrate ( ) accumulates in tea soils, resulting in a great potential for diffuse pollution. Nitrification in tea soils remains poorly understood. The purpose of this study was to investigate net and gross nitrification in three tea soils with varying productivity, their adjacent forest and vegetable soils. The results showed that neither net nor gross nitrification rates were significantly related to soil pH. The net nitrification rate increased with increasing tea production, and when soils were incubated with ammonium sulfate. The ammonium ( ) added to the vegetable soil was immediately and completely nitrified, but that in the tea and forest soils was nitrified more slowly. About 60–80% of the in the tea and forest soils was nitrified during 35 d of incubation, indicating nitrifiers do exist in these soils. Significantly higher gross nitrification rates were observed in vegetable and tea soils with high and medium production than in forest and tea soils with low production. Microbial consumption (immobilization and nitrate respiration) accounted for 30 to 70% of the mineralized nitrate nitrogen ( −N) with the lowest in the forest soil, and no significant difference between the tea and vegetable soils. Nitrogen fertilizer stimulated soil nitrification. In conclusion, the types of land use and their management are more important than soil pH for soil nitrification. High nitrogen application rate is the main cause of accumulation in tea soils and should be reduced to minimize pollution of water resources.


Background:
 Stroke and myocardial infarction (MI) prevalence varies by race/ethnicity, as do the risk factors.

 Methods:
 We included biyearly data from the 2011-2019 Behavioral Risk Factor Surveillance System (BRFSS) surveys of adults (age ≥18) in the United States. We describe survey-weighted prevalence of self-reported stroke and MI by race and ethnicity. We also describe the prevalence of modifiable vascular risk factors in patients with stroke and MI.

 Results:
 The weighted number of U.S. participants represented in BRFSS surveys increased from 237,404,549 in 2011 to 251,703,709 in 2019. Stroke prevalence increased from 2.9% in 2011 to 3.4% in 2019 (<0.001), while MI prevalence did not change over time (4.3% in 2011; 4.2% in 2019). The prevalence of stroke and MI was highest in American Indian/Alaskan Natives (AI/AN) at 5.6% and 7.5% in 2011 and 2019, respectively, compared to 3.2% and 4.8% for whites (p<0.001). Prevalence trends by race/ethnicity are in Figure 1. Modifiable risk factors are in Tables 1&2, which show that AI/AN consistently have the highest or second highest proportion with ≥4 risk factors.

 Conclusion:
 Prevalence of self-reported stroke, but not MI, is increasing in the United States. AI/AN consistently had the highest prevalence from 2011-2019 and the highest overall burden of modifiable vascular risk factors, rendering this group more vulnerable to a recurrent vascular event.


According to the characteristics of sign word of gesture language for Chinese Sign Language (CSL), a greedy clustering algorithm along the time axis (GLATA) is proposed in this papcr. A fast training algorithm and a fast recognizing algorithm basing on GLATA are given. and they are applied in gesture recognition for CSL. The experimental results show that this method is more effective than HMM in gesture recognition.

Exploiting the unique ability of the European Transonic Windtunnel to vary the free-stream dynamic pressure at constant Reynolds number (and vice versa), the effective aerodynamic wing twist is determined by comparing the normalized pressures measured at certain wing sections. This task is performed by a computer program which processes the pressures of one individual wing section that have been acquired at the same Mach and Reynolds number, but different levels of tunnel pressure and temperature, i.e. different dynamic pressures. To obtain the geometric twist, the induced downwash angle which originates from the effective wing twist alone is estimated and added to the effective wing twist. This paper describes the effect of the wing twist on the measurement results, the mathematical model used to determine the effective aerodynamic twist and the features of the above mentioned software. The relationship between wing bending and twist in the case of a swept wing and its impact on the results is discussed as well as the computation of the geometric wing twist. The last section contains an assessment of the accuracy and the description of the advantages and disadvantages of the presented method.


As a significant component of rotation machinery, bearing plays a role in supporting and transmitting power. However, bearings are subject to complex operating conditions and are prone to failure. To avoid ineffectiveness and improve the reliability of bearings, a data-driven method is used to predict the remaining useful life (RUL). However, this method is less stable and can only forecast the RUL of bearings under training sample conditions. An ensemble deep, long-term, and short-term memory (EDLSTM) method is proposed to solve this problem. First, the feature of the forecast-bearing RUL was extracted including time-domain features, frequency-domain energy features, and Shannon entropy. Then, a deep long- and short-term memory network prediction model of the bearing RUL was constructed. To resolve the instability of DLSTM predictions, multiple DLSTMs were ensembled using the maximum information component (MIC) criterion. The model i trained using bearing data with different failure modes under difficult operating conditions to improve the predictive stability of the model. Finally, an EDLSTM was constructed to achieve the bearing RUL prediction. In the prediction result of the training set, the cumulative relative accuracy (CRA) was above 0.9 for most of the bearings. According to the experimental results in the test set, the mean CRA was over 0.80. For some of the bearing's RUL, the CRA was more than 0.90. The above results show that the proposed approach can effectively predict the RUL of a bearing and has a more stable prediction ability than the bagging integration method.


Topology control of wireless sensor networks is the focus study of wireless sensor networks application.Based on the analysis of existing topology control algorithm a dynamic clustering algorithm was proposed,which is based on energy forecast and agent-cluster-head.The clustering method characterized by distinguishing hot zones reduces the funnel effect in WSN;the introducing of agent-cluster-head not only makes the topology can be updated in partial area but also reduces the complexity of the cluster-head voting algorithm;the alternation of the cluster-head based on energy forecast balances the energy consumption of all sensor nodes.


The effect of rhenium additives and support (Al 2 O 3 ) texture on the state and activity of palladium in liquid-phase hydrogenation of m-nitrobenzoic acid was studied. The higher activity and selectivity of bimetallic systems compared to Pd catalysts was caused by higher Pd dispersion and thermal stability. Hydrothermal treatment changed the support macrostructure, therefore, the Pd:Re ratio at the surface decreased from 4: 1 to 1:1 in the course of the catalyst preparation. The catalyst obtained showed a higher activity: the m-aminobenzoic acid yield reached 91 mol % during 0.5 h with a selectivity of 93%


This study aimed to investigate community knowledge, attitudes, practice, and concerns of adults 18-45yrs towards COVID 19 vaccinations in Chandigarh, India. A rapid online survey was done, and forms from 731 people were collected from 24.08.21 to 5.10.21. The primary outcome variable was the general public's willingness, knowledge, and attitude towards COVID-19 vaccination. The associated factors were identified using regression analysis. A sample of 73% of people participated and completed the study questionnaires. Only 70.3% of the people received the vaccination, and 70.9% of participants gave no history of previous COVID-19 infection. Just above half of the participants, 50.2%, believed to know the vaccine's effectiveness, whereas 88.1 % (644) participants understood the importance of vaccination against this disease. Despite limitations, surveys are a suitable method to evaluate and assess attitudes and concerns of the general population about COVID-19 vaccination.


A trench gate type 600V GaN power MOSFET structure with Al2O3 gate oxide has been designed and simulated for obtaining optimum device and process parameters for fabrication. As a result, when the trench gate depth is 2.4 μm, the breakdown voltage is 620V and the on resistance is 0.4Ωcm2, which is relatively very low on resistance comparing with the same trench gate Si power MOSFET structure.


The stone resources have always been a major source of material in the building and, in particular, as raw material to create the masterpieces of sculpture and architecture that are now part of the cultural heritage of the humanity. Therefore, knowledge of stone resources, their mineral-petrographic features, their use and quarrying and working techniques from antiquity to the present, can provide a broad overview of the historical and cultural significance of these materials, stressing the importance of a relevant economic activity in the history and traditions of different cultures that have developed over the centuries in the Mediterranean area. In particular, in Piedmont, stone has always been the most widely used building material, characterizing the strong architectural identity of the city of Turin. Here the stone have been widely used in the historical and contemporary buildings, monuments and urban art. From Roman times to the '700, marbles were the rocks used in construction of more value. Starting from '800, granites and other silicate rocks were progressively used thanks to the development of technologies for their exploitation and processing. The study of stone resources is also of particular importance for the proper preservation of architectural and artistic heritage. Often, the task of restoration of works of art was carried out with stones aesthetically similar to the originals for color. Only recently, chances to find the same original material, identifying the place of origin, has become object of study and interest. The great variety of ornamental and building stones found in Turin is certainly due to the highly composite geological nature of our region. In Piedmont, in fact, there are geological features very different from each other as the western portion of the metamorphic Alpine chain, the sedimentary Tertiary Piedmont basin (Langhe and Monferrato) and a small sector of the Northern Apennine. Turin Urban Geosite represents the symbol place of interaction between man and the geological environment also in terms of cultural resources and development of the territory.


The present work aimed to dye silk fabric with natural dye extracted from the Artemisia Herba Alba plant from its leaves on pure silk dyeing fabrics with different dyeing conditions such as time, temperature, and pH value in the presence of Alum as a mordant, which had given different colors and shades to promote the use of natural silk fiber. Optimum results were obtained. Silk fabric was dyed using pH 5 for 45 minutes at temperature 80oC and 1:40 liquor ratio. Finally, the dyed mordant samples were thoroughly washed and dried at ambient conditions. The results obtained us successfully characterized dyed silk fabric by studying with a Fourier Transform Infrared thermogravimetric (TGA) properties, (FTIR) analysis technique, and X-ray diffraction (XRD). Improvement in the dyeing process may have been attributed to the improvement in the molecular structure of the chemical bonds in silk fabrics. This work gives an opportunity to use a new traditional natural dye that meets the future environmental technology that exhibited fantastic dyed patterns of high quality.


Abstract Objectives: The primary aim was to compare the objective and the subjective assessments of hearing aid use among elderly people at a 6-month follow-up after fitting. A secondary aim was to determine whether advanced knowledge of follow-up impacts hearing aid use. Design: Hearing aid use was assessed by datalogging (objective) and self-report (subjective) 6 months after initial fitting. Participants were also randomised to an intervention (informed of 6-month follow-up at fitting) or control group (informed just prior to follow-up). Study sample: A total of 181 hearing aid recipients ≥60 years (mean age = 79.2 years). Results: Daily hearing aid use based on datalogging (mean = 6.12 h, SD = 4.94) was significantly less than self-reports (mean = 8.39 h, SD = 5.07). More severe hearing impairment and prior hearing aid experience were associated with increased hearing aid use. Advanced knowledge of the follow-up had no significant impact on use, which did not differ between intervention (n = 93) and control (n = 88) groups. Conclusions: Elderly people typically use their hearing aids for a substantial part of the day in the 6 months after fitting, but tend to overestimate their usage. Datalogging is recommended to identify those who do not use or rarely use their aids so that appropriate rehabilitation and support can be provided.


Abstract The paper reflects on the tension that the process of sensing a nation brings to the formation of a post-colony in Southeast Asia. The "aesthetic" in this context creates forms of sensibility of the "national," rendering it present in the world and endowing it with certain identity-effects. On the other hand, it also posits an exceptional singularity, at once discriminating against subjectivities that resist to be contained within the national project and achieving the distinction of autonomy. This process foregrounds moments of finitude, improvisation, and intimacy, aspects of the aesthetic that are central to the crafting of the national and its art.


Introduction The COVID-19 pandemic presented challenges to delivery of reproductive health services. To explore effects, we examined patterns of contraceptive use, service access and pregnancy planning in the year following the first UK lockdown. Methods The Natsal-COVID Wave 2 survey was conducted in March-April 2021, one year after the first lockdown began in Britain. We analysed a subset of sexually-active participants aged 18-44 years and described as female at birth. We estimated differences in outcomes by age and markers of vulnerability. We examined changing contraception use, access to and unmet need for contraceptive services, and London Measure of Unplanned Pregnancy scores (LMUP;range 0-12). Results Of 1,488 eligible participants, 78.0% were considered at risk of unplanned pregnancies. Of 441 at-risk participants who tried to access contraceptive services, 16.4% faced barriers. Young participants (18-24 years) were most likely to report trying to access contraceptive services (38.4%;(32.2, 45.0);vs 28.4% overall) and to face barriers doing so (OR: 2.87 (1.36, 6.06)). Encountering barriers was more likely among participants reporting no educational qualifications and those reporting symptoms of anxiety or depression. 199 participants reported a pregnancy in the last year. Pregnancies to young participants were less likely to be 'planned' (difference in mean LMUP score: -2.95;(-3.91, -1.99)). Less 'planned' pregnancies were associated with lower social grades and becoming unemployed. Discussion Young and vulnerable participants were more likely to report difficulties accessing reproductive services and less planned pregnancies during the pandemic. In navigating pandemic recovery, sexual health services should consider the needs of these at-risk groups.


The interpretation of nominal compounds is one of the most difficult problems in natural language processing. This paper proposes a new algorithm for the automatic interpretation of compound nominalizations in Chinese. A maximum entropy model is applied to label four coarse-grained roles involved in compound nominalizations. The classification features used are automatic extracted functional lexicalized paraphrase patterns. The experimental result shows that the method is superior than previous works that use manually coded paraphrase patterns.


Although glucocorticoids (GCs) are effective in controlling asthma in the majority of patients, a subset of asthmatics fails to demonstrate a satisfactory response, even to systemic GC therapy. This population is referred to as being "steroid-resistant". The actual mechanism underlying steroid resistance in asthma remains to be elucidated. Methods: We have investigated how dexamethasone (DEX) regulates asthmatic phenotypes in a murine model of asthma, in which mice received i.p. immunization twice, followed by two bronchoprovocations with aerosolized OVA with a one-week interval, which we have recently described. Results: Pretreatment with DEX resulted in an inhibition of NF-κB activation in asthmatic lungs, and also inhibited bronchoalveolar lavage (BAL) levels of NF-κB -dependent cytokines such as TNF-α and CC chemokines [eotaxin and monocyte chemotactic protein (MCP)-1]. DEX was effective in suppressing airway hyperresponsiveness (AHR) at 10 h, Th2-dependent asthmatic phenotypes such as airway eosinophilia, BAL levels of Th2 cytokines (IL-5 and IL-13), and mucin production. However, DEX failed to suppress BAL levels of CXC chemokines [macrophage inflammatory protein-2 (MIP-2) and keratinocyte-derived chemokine (KC)] and airway neutrophilia. Conclusion: Airway neutrophilia is among the phenomena observed in patients with severe GC-resistant asthma. This study will provide insight into the molecular basis for airway neutrophila seen in steroid-resistant asthma. Further studies are required to delineate the underlying mechanism of CXC chemokine expression in asthma.

A one solar mass, zero-metal star is evolved through the peak of the major core helium flash and compared with models for which the metal abundance is Z = 0.0001 and 0.02. Before central hydrogen is exhausted, and long before the major core helium flash occurs, the Z = 0 model experiences a helium-burning thermal runaway at the center. As this model evolves along the giant branch, recurrent helium-burning thermal runaways are initiated at the base of the hydrogen-burning shell. The thermal structure of the electron-degenerate core of the Z = 0 red giant is completely different from that of the higher Z red giants. As a result of this structure, the major flash begins at a location much farther from the center than in the higher Z cases. Most significantly, during the flash in the Z = 0 model, the outer edge of the convective shell formed in the helium zone extends into layer containing hydrogen, which does not occur in the Z = 0.0001 or Z = 0.02 cases. 61 refs.


The motion of a vortex filament in an inviscid incompressible fluid is described by the Biot-Savart law. The localized induction equation (LIE) is the simplest model to capture the leading-order behavior of this motion $[1, 2]$ . Hasimoto [3] showed that the L1E is equivalent to the cubic nonlinear Schr \"odinger equation (NLS) for a complex variable, implying that the LIE is completely integrable. Magri [4] unveiled the $ \mathrm{b}\mathrm{i}$ -Hamiltonian structure that underlies this integrability and thereby manipulated a recursion operator to generate an infinite sequence of integrals in involution and commuting Hamiltonian vector fields.


Gamification, the use of game elements in non-game contexts, has been successfully used to motivate people to reach their goals more efficiently or turn unpleasant tasks into fun ones. However, most gamified systems are conceptualized for a younger audience and do not account for age-specific changes in the motivation to play or the perception of game elements. To inform the design of gamified applications targeting elderly people (aged 75+), we investigated their gaming experiences, what affects them positively while playing and their attitudes towards the most commonly used game elements. We report findings from semi-structured interviews and a storyboard-based game element assessment (N=18, mean age=84.61), indicating that the main motivation to play is socializing, that participants avoid competition and prefer collaboration and care-taking as well as that badges and points are considered meaningless and provide a level of visibility that puts participants under pressure.
