String theorists claim there are at least nine dimensions to the universe. So why is our world in only three? String theory describes subatomic particles as infinitesimally tiny bits of vibrating string. It also predicts extra spatial dimensions, which are hidden because they are tightly curled up or because matter and forces are barred from them. Nothing in the theory dictates the number of accessible dimensions, though. Now, Andreas Karch of the University of Washington, Seattle, and Lisa Randall of Harvard University have done an analysis that they say shows why a 3D world is the most likely.The researchers assumed that the universe began as a nine-dimensional volume filled with surfaces, or "branes," of every possible dimensionality: from 1D strings to 9D hypercubes.As this universe expanded, any branes that collided would be annihilated, like what happens when matter and antimatter meet. But 3D branes may have survived because geometrically they have a harder time "finding" each other, says Randall.The only alternative reality would be 7D branes, which compensate for self-destruction by filling up more space, she and Karch conclude in the October edition of Physical Review Letters. But, notes Karch, gravity is too weak in 7D to hold planets in orbit. Theoretical physicist David Tong of Cambridge University in the U.K. says the researchers have yet to explain how gravity—the one force that can radiate into extra dimensions—becomes confined to the 3D brane. But if that can be worked out, Tong thinks brane evolution could be a fruitful new line of research.


Five chlorobenzenes(CBs)including 12-dichlorobenzene(12-DCB),13-dichlorobenzene(13-DCB),14-dichlorobenzene(14-DCB),124-trichlorobenzene(124-TCB),and hexachlorobenzene(HxCB)in eleven selected municipal sludges from varied cities of China were determined by GC/MS.Total content of chlorobenzenes(ΣCBs)in all these sludges ranged from 0.010 to 6.917mg·kg -1,decreasing in the order:Lanzhou sludgeBeijing sludgeDapu sludgeWuxi sludgeYuanlang sludgeGuangzhou sludgeFoshan sludgeShatian sludgeXi′an sludgeZhuhai sludgeShenzhen sludge,with most of them less than 1.0mg·kg -1.CBs with higher molecular weight such as 124-TCB and HxCB were detected in all the sludges,generally less than 0.5mg·kg -1,but no sludge was detected for 13-DCB.Among chlorobenzenes,only one or two of them was predominant,thus exhibiting specific distribution patterns.Those chlorobenzenes with higher concentration were found mainly in Lanzhou sludge and Wuxi sludge.The type and concentration of chlorobenzenes in different municipal sludges were related to the sources of wastewater,wastewater-treating methods,sludge types,physical-chemical properties of chlorobenzene themselves.


We present some ideas for course material for the introductory teaching of programming that are based on the principle of allowing the students to be the domain experts. The idea is that the students' familiarity with the domain of discourse will make course material more motivating, and that it will be more likely that they will be able to model the concepts and artifacts being discussed. This approach thereby seeks to scaffold the students' understanding of programming-related concepts. For reasons discussed in the paper, we have chosen mobile phone technology for this discussion, but there is no reason why the same principles should not be applied to other culturally-accessible domains.


As a photocatalysis environmental material, nanometer TiO_2 can effectively degrade pollutants, and mineralize them to CO_2, H_2O and other inorganic small molecule substances. So nanometer TiO_2 can be applied to wastewater treatment, air cleaning , sterilization and deodorization. In this paper, a review is given on its preparation and photoinduced superhydrophilicity mechanism of nanometer TiO_2 , and the research progress and application prospect of nanometer TiO_2 in self cleaning building materials and sterilization etc.


This paper presents the results of an extensive experimental investigation into the performance of a short multi-grooved bearing subjected to a range of static and alternating loads. Lubricating oil was supplied, at pressures of up to 2000 lb/in2, to capillary type restrictors connected to 10 closed-end axial grooves in the bearing. The bearing had a length/diameter ratio of 1/3 and operated with a journal speed and load frequency of 327 c/min.Measured load capacity, stiffness, and flow characteristics indicate that bearings of this type have a significant load-carrying capacity at zero journal speed and that the load capacity is increased by journal rotation. A feature of the journal behaviour under alternating loads is the movement of the journal centre along a straight line coincident with the load plane.The extensive oil film pressure surveys indicate for the first time the pressure distribution within narrow hydrostatic bearings and provide a basis for a realistic theoretical analysis of this type of...


Reviti Limited, a wholly owned subsidiary of Philip Morris International (PMI), incorporated 5 July 2018, sells life insurance in the UK, with plans to expand into other markets.1 Incentivising smokers to switch to PMI's heated tobacco product IQOS, Reviti generated media attention.1 2 The advertised discounts on Reviti's premiums average 50% for smokers who quit tobacco and nicotine altogether for over a year, 25% for smokers who switch to IQOS for >3 months, and 2.5% for those who use e-cigarettes. The relative discounts on premiums imply that switching to IQOS is 10 times healthier than using e-cigarettes. Further, Reviti offers the e-cigarette discount only at policy inception, with no switching incentive; and notably omits a discount for nicotine replacement therapies. Reviti's website claims IQOS is the only available 'science-backed smoke-free alternative' (figure 1). Unacknowledged is that the evidence for IQOS derives exclusively from PMI-funded research, and that the company's human studies fail to show consistently lower levels of some toxins for IQOS relative to conventional cigarettes.3 4

Defamiliarising the Familiar: There is an inherent paradox in teaching film to secondary students. On the one hand we know too much, we understand popular film because we have seen examples of it so many times on television and at the movies. On the other, most teachers have little training in how film communicates. Thus, whilst we recognise and understand film with ease, we find it difficult to teach the underlying principles because their appearance are often so transparent and accessible. The principles of filmmaking are too familiar. Hence we need to step back and defamiliarise the seemingly simple process of communication that film presents. Consider a crucial sequence in Proof when Andy is sent to the park by Celia in search of Martin. At the park he sees Martin taking photographs while Celia lures Bill, the dog, away from Martin with a biscuit. Andy tries to avoid Martin's camera but is caught dodging behind a tree. Later, Andy protects Celia by failing to tell Martin that he was at the park and saw Celia lure Bill away. This is a pivotal moment in the film as it exposes Andy's deceptive behaviour, the very thing Martin cannot forgive. Hence the relationship is severely damaged and Celia has a (brief) victory in her love/hate battle with Martin.

The objective of this paper is to investigate lessons taught for online and face-to-face sections in a Flipped classroom for EFL undergraduate students. The platform used for the online learning was English Discoveries Online (EDO). Furthermore, the students' English level based on the platform placement test was Basic 2. The method of the research is qualitative employing descriptive and reflective field notes as the main data gathering, as well as documents recorded from the platform and interview as the supporting tools of gathering data. The results show that the teacher never used the platform communication tools to share information with the students during the online section. Other tools such as magazines, games, and grammar books were also not used. Those were under the consideration of teacher's sympathy to the students; as she knew that it would be too much for them. In addition, the teacher claimed that the lessons in the platform were too western-style, therefore activities that were connected to students' real life and engaged students' point of views were crucial. Finally, the use of first language to engage students during face-to-face class worked well.

This chapter examines the potential discrepancies in the regulation applied to overseas issuers, as opposed to domestic issuers, of four leading financial centers. They are New York, London, Hong Kong, and Singapore. It consists of three substantive sections. The first section will reviews existing literature and empirical evidence concerning the motivations and current state of cross-listing. The second section examines the listing route for an overseas issuer and inquires how it might differ from a domestic listing in the host country. This chapter particularly concerns the potential discrepancies of rules between a foreign listing and a domestic listing and asks if those discrepancies would lead to better or inferior investor protection. The third section examines the continuing regulation of foreign-listed companies, reviewing some regulatory concerns involving cross-listed companies and discussing what can be done to curb the problems, for instance, through regulatory cooperation between home and host regulators.


A new approach which can increase wheat yield was discovered by breeding two lines hybrid wheat, with the use of Thermo-photo-sensitive Nucleus-male Sterile wheat C49S. However, it had been studied for many years, the result showed that why it were inhibited from applying to producing wheat was the influence of climate in the plain of Jianghan and the disadvantage of C49S. In the meanwhile, it also showed that some problems can be solved, through choosing the appropriate research direction.

Impaired phonological processing has been found to have a reciprocal casual association with the reading ability of people with reading difficult‐ies. Further, there is growing evidence that problems in phonological processing are present at birth as research shows that infants with a family history of these disorders have atypical neural electrical responses (ERPs) to speech stimuli. However, the nature of the phonological deficit is not clear. This study examined the phonological development of at‐risk 9‐ to 12‐month‐old infants (n=18) and a control group (n=18). Their discrimination performance was evaluated using the habituation‐dishabituation task to test their ability to discriminate the confusable native contrast, /fa‐tha/ and the non‐native contrast, /k'i‐q'i/ from Werker and Tees (1984). In line with core phonological deficit hypothesis and hereditary accounts of reading difficulties, infants' attunement to their native language was significantly correlated with parental phonological ability meas...


A mathematical model of performance simulation for oblique detonation wave engine(ODWE) was introduced.Based on computer language Fortran and the assumption of calorically imperfect gas,the performance simulation of ODWE under given flight condition was obtained.The underdriven and overdriven modes were analyzed,and the ignition window and the effect of different coming flow on the performance of ODWE were also included.It indicates that the mathematical model is reliable in all ignition window.When coming flow is given,specific impulse increases and then decreases with the shock wedge angle increasing,and specific impulse keeps constant in the underdriven mode and then decreases in the overdriven mode with the oblique detonation wedge angle increasing.As Mach number of coming flow increases,the optimum operation window becomes narrow for the corresponding CJ wedge angle decrease.It suggests that ODWE should operate in the underdriven mode to achieve optimum performance.


While fixing a number of tapeworms (Anoplocephala perfoliata Goeze) from the small intestine of the horse, I came across a small tri-radiate specimen. This abnormality has previously been described by Neumann (2), but only briefly, and without any account of the internal anatomy. It therefore seemed advisable to compile a short account of the most salient characteristics. For the material I am indebted to Dr C. L. Boulenger, Helminthologist of this Department. I have also to thank Professor L. G. Neumann for obtaining for me a copy of his paper.

Abstract Dibenzyls are essential building blocks that are widely used in organic synthesis, and they are typically prepared by the homocoupling of halides, organometallics, and ethers. Herein, we report an approach to this class of compounds using alcohols, which are more stable and readily available. The reaction proceeds via nickel-catalyzed and dimethyl oxalate assisted dynamic kinetic homocoupling of benzyl alcohols. Both primary and secondary alcohols are tolerated.

The growth of Wrocław Meat breed, created by Prof. Bolesław Nowicki in 1998, has been analysed in the thesis. The study was carried out in the Department of Genetics and Animai Breeding at the Wrocław University of Environmental and Life Sciences. The research included 57 pigeons which were divided into two groups, The first group consisted of pigeons coming from a single egg clutch, the other group incJuded pigeons from a two egg cJutch. There is no use leaving one egg in a nest since there have not been any significant differences between the weight of 4-week-old pigeons coming from a single or twin clutch. The decrease of 24h weight gain has been observed after the fourth week of life. It seems to be the best time for slaughtering the birds. Further fattening would not be economicaJly justified.


Objective:To explore the effect of maternal depression on infant temperament.Methods:Infant temperament at 6 and 14 months and maternal depression level were surveyed by questionnaires among 269 mothers.Results:Infant temperament from 6 to 14 months was stable,at 6 months,there was significant difference in infants' activity level among high,medium and low depressive mothers,but the differences did not appear at 14 months;there was significant difference in temperament level after limitation among high,medium and low depressive mothers at 6 and 14 months.Conclusion:Infant temperament is really affected by maternal depression,although,a small distortion of infant temperament exists in highly depressive mothers.


While professional courses have had a long association with work-integrated learning (WIL), issues around graduate employability, and insufficient interaction between university and industry learning and assessment, have led more recently to greater investment in WIL in the Higher Education sector (Goulter, 2007, Patrick et al., 2008). Guided by WIL principles of the Innovative Research Universities (2008), as well as notions of criticality in WIL (Billett, 2009) and hybrid spaces in teacher education (Zeichner, 2010), this paper explores the potential of an e-Portfolio to enhance graduate employability among pre-service teachers in a one-year professional program. The authors analyzed transcripts of interviews with key stakeholders — including Professional Experience Advisory Committee (PEAC) members, pre-service teachers, and program lecturers — as well as policy, curriculum, and course accreditation documents, and pre-service teacher work samples. Findings support the potential of the e-Portfolio as a learning, assessment, and employment tool – a platform to facilitate exploration, construction, presentation, and critique of evidence (Bloomfield, 2009) against the graduate professional standards (QCT, 2006). While findings point to the e-Portfolio as both product and process (Bloomfield), they also reveal the need to further consider its current articulation with issues of policy, pedagogy, and curriculum, as well as to engage more broadly with stakeholders to determine how to enhance inputs and outcomes (Oliver, 2010).


The main objective of the present study was carried to evaluate the possibility of enhancing antioxidant activities by using 10% of thyme, carrot and hibiscus powder fortified to crackers as natural colored antioxidants to produce healthy crackers, chemical composition and rheological properties were carried out, determination of phenolic compounds and antioxidant activity% noticed that thyme powder had the highest level of total phenols (12366 mg/100g), followed by carrot powder which was (5087.4 mg/100gm) and hibiscus had (4262.9 mg/100g), while antioxidant activity were 96.7% for thyme, 89.59% for carrot and 86.17% for hibiscus. Also, this work aimed to study the anti-hyperlipidemic activities of crackers with 100% wheat flour and crackers fortified with natural additives (thyme, carrot and hibiscus powder) on rats. The experiment was performed in 36 male rats distributed into 6 equal groups. Group (1) was kept as a normal control (fed on a basal diet), while rats of the other five groups were fed on hypercholesterolemic diet for 8 weeks to induce hypercholesterolemia. Rats of group (2) were left as a positive control and those of groups (3, 4, 5 and 6) were given unfortified cracker 100% wheat flour (CWF), 10% thyme(Cth) , 10% carrot (CCa ) and 10% hibiscus (Chi). The results revealed that rats consumed crackers fortified with natural additives decreases adiposity index, body mass index, Serum Cholesterol, Triglycerides (TG), Low density lipoprotein cholesterol (LDL-C) and Very low density lipoprotein cholesterol (VLDL-C), while there was an increase in serum HDL-C. Also showed decreases in serum ALT, AST, AP, Uric acid, Urea and Creatinine levels. The best results showed in thyme crackers then carrot followed by hibiscus for the treatment of hypercholesterolemic.

For the tax system to function efficiently, it is necessary for the tax authority to provide advice to taxpayers. What is the consequence however where the advice is predicated on an error of law, and HMRC then later seeks to correct this error? That is precisely the question that came before the Court of Appeal in HMRC v Hely-Hutchinson [2017] EWCA Civ 1075; [2017] S.T.C. 2048. The judgment underlines the difficulties that taxpayers will face when seeking to rely upon HMRC assurances and when seeking to invoke the doctrine of legitimate expectations generally. The specific facts of the case might however be viewed as limiting the scope of the judgment.


Cycle identification via the rainflow‐algorithm is implemented online in a model predictive controller (MPC) for Li‐ion batteries. This is achieved by externalization of the cycle identification from the optimization problem. The limitation for cyclic aging estimation due to short prediction horizons is overcome by updating and utilizing a State of Charge memory. Furthermore, a comprehensive plant model for Li‐ion batteries is presented with novel submodels for calendric and cyclic aging. The novel MPC is implemented in the ACADO Toolkit and tested with the aforementioned plant model. Simulation results indicate that—even without tuning—the novel MPC clearly outperforms a rule‐based controller and an extensively tuned MPC from literature.


This study identifies the structure and material characteristics of the mural paintings in Daeungjeon at Ssanggyesa temple in Jindo by conducting scientific research and analysis including microscope examination, SEM-EDS, XRD, particle size analysis, and others. According to the analyses, the murals were considered to be of a typical soil mural style for Korean Buddhist murals, given that the walls were made of sand and soil and the murals had layers consisting of wall layers and a finishing layer. However, some finishing layer used calcite, while some ground layer used zinc white beneath the thick paint. In addition, there were similar features to those found on the surfaces of oil paintings such as cracks along with the paint layer, high gloss on surfaces, and thick brush strokes in many areas. It was found that the walls on which the murals were painted were made of soil but that the paint layer was created based on the oil painting technique using drying oil. It determined that the murals were painted in a unique painting style that is rarely found in other typical Buddhist murals in Korea.


Background: Several changes are observed in maternal thyroid function during pregnancy and failure to adapt to these physiological changes results in thyroid dysfunction, especially if complicated by the presence of thyroid antibodies. The presence of TPO-Ab is associated with increased rate of pregnancy complications such as miscarriage, preterm delivery, placental abruption, pregnancy-induced hypertension, intrauterine death and low birth weight. Objective of this study was to study the effect of anti-TPO Ab positivity on pregnancy outcome and estimate the prevalence of anti-TPO Ab in euthyroid obstetric women.Methods: This observational study enrolled 500 euthyroid pregnant women, age 20-35 years, up to 20 weeks gestation. Venous blood samples collected and analyzed for the anti TPO Ab levels. On the basis of anti TPO Ab positivity they were divided into two groups, anti-TPO Ab positive and Ab negative group. These two groups were followed up till delivery or abortion and compared for maternal and fetal outcomes.Results: Prevalence of anti-TPO antibody positivity was 5.2% in euthyroid obstetric women. Most of anti-TPO Ab positive women were overweight. There were higher numbers of miscarriage (11.54%) in anti-TPO Ab positive euthyroid pregnancies than (2.53%) in antibody negative women. Incidence of low birth weight babies was 4-fold higher in anti-TPO Ab positive women. More than two-fold increase in incidence of placental abruption in anti-TPO Ab positive women. Parity, anaemia, gestational hypertension, preeclampsia, GDM, PROM, PPH, low Apgar scores, NICU admission, IUD and neonatal death were not significantly associated with anti-TPO Ab positivity.Conclusions: Anti TPO Ab positivity significantly associated with pre-pregnancy BMI, miscarriage rates and low birth weight of newborns.


— Nowadays, a main resort for delivering software with good enough quality is to design, create, implement and maintain test cases that are executed automatically. This could be done on many different levels, however graphical user interface (GUI) testing is the closest one to the way the real user interacts with the software under test (SUT). The aim of this paper is to determine the most popular GUI automated tools for software testing among a list of 52 candidates and compare them according to their features, functional and non-functional characteristics.


Background: There is a general paucity of cysteine residues within the passenger domains of autotransporter proteins. Results: Distantly spaced cysteines forming disulfide-bonded loops or those enclosing structural elements are secretion-incompetent. Conclusion: Only closely spaced cysteine pairs are compatible with the autotransporter pathway. Significance: Secretion of folded peptides by the autotransporter pathway is limited; hence autotransporters lack large disulfide-bonded loops to remain secretion-competent. Autotransporters are a superfamily of virulence factors typified by a channel-forming C terminus that facilitates translocation of the functional N-terminal passenger domain across the outer membrane of Gram-negative bacteria. This final step in the secretion of autotransporters requires a translocation-competent conformation for the passenger domain that differs markedly from the structure of the fully folded secreted protein. The nature of the translocation-competent conformation remains controversial, in particular whether the passenger domain can adopt secondary structural motifs, such as disulfide-bonded segments, while maintaining a secretion-competent state. Here, we used the endogenous and closely spaced cysteine residues of the plasmid-encoded toxin (Pet) from enteroaggregative Escherichia coli to investigate the effect of disulfide bond-induced folding on translocation of an autotransporter passenger domain. We reveal that rigid structural elements within disulfide-bonded segments are resistant to autotransporter-mediated secretion. We define the size limit of disulfide-bonded segments tolerated by the autotransporter system demonstrating that, when present, cysteine pairs are intrinsically closely spaced to prevent congestion of the translocator pore by large disulfide-bonded regions. These latter data strongly support the hairpin mode of autotransporter biogenesis.


Objective To prove the inhibitive effect of intraoperative doses of all-trans retinoic acid(ATRA) in preventing after cataract formation after rabbit lensextracapsular extraction and also to find out the probably effective dose range of ATRA's inhibition. Methods Balanced irrigating solutions with different concentration of ATRA were introduced in the testing groups,in the meanwhile the normal balanced irrigating solution in the blank control group during the extracapsular cataract extraction.One month after intervention,PCO was graded clinically as the index of after cataract.Furthermore,proliferation of lens epithelial cells was evaluated histologically by light and electron microscope.Results After cataract formation of the rabbits after lens extracapsular extraction decreased with the ATRA concentration rising up,which was significant in the statistics evaluation(P0.01).PCO evaluation was not significant statistically between the 10 μ g/mL and 20 μ g/mL group(P=0.544).The same conclusion was obtained from histological examination. Conclusions This study suggests that ATRA in intraoperative balanced solution irrigation can inhibit lens epithelial cell proliferation on posterior capsule and thus significantly prevents the development of after cataract in rabbit eyes.The effective dose concentration of ATRA inhibition was from 2 to 10 μ g/mL.


The typical conditions employed for the analysis of inorganic explosive residues by suppressed ion chromatography result in runs time exceeding 30 minutes. Recent efforts to speed up the analysis time have involved coating monolithic or small particle size reversed phase columns with cationic surfactants. However, eluent pH constraints have made such systems incompatible with suppressed detection, rendering the analysis insensitive. This study employed a Waters hybrid particle 2.5μm silica C18 column coated with di-dodecyldimethylammonium bromide (DDAB) to form an anion exchange column. This column was stable over a pH range of 1-12 which allowed employment of bicarbonate-carbonate eluents and suppressed conductivity detection. At an optimum flow rate of 1.0mL/min seven anions associated with explosive residues were separated in under 20 minutes. The optimised conditions were evaluated for linearity, specificity, repeatability and limit of detection. The limits of detection were below 50ppb for chloride, nitrate and chlorate; 100ppb for nitrite and sulphate; and approximately 500ppb for thiocyanate and perchlorate. The method was used to analyse swabs of surfaces obtained from field trials of five separate explosive devices.


After relaying technology is introduced into the cellular system, many research fields emerge. Among them, resource allocation strategy for distributed and centralized scheduling is an important topic. This paper analyzes and compares the differences between these two scheduling modes, including both system performance and signaling overhead. Two practical scheduling strategies and an efficient routing metric are proposed for them. Simulation results for several typical scenarios can show the comprehensive system performances after these new technologies are adopted.


This chapter examines Prieto's childhood and upbringing in Africa to confront the primitive stereotypes about pre-colonial African societies. Since there is no documentation surrounding Prieto as a child in West Africa, pinpointing the origins of an enslaved African taken to the Americas is challenging. As a result, the focus turns to establishing the significance of Yoruba kinship groups, oral traditions and religious training in Sango. Prieto's West African childhood influenced Prieto's leadership in Cuba. The chapter also discusses the likelihood of Prieto's enslavement surrounding the expansion of the kingdom of Oyo and the destruction of the slave trading port, Badagry.


The exciton binding energies in finite-potential quantum dot discs of GaAs are obtained and the eigenstates and the eigenvalues of the exciton are calculated. We present the exciton binding energy for different values of the disc radius (R )a nd the disc half-width (L/2). The exciton-state stability for large and small sizes of the dot is discussed. We compare our results with the existing theoretical and experimental results. Our results give good estimates for the optimal quantum dot disc geometry, and represent useful data in studies of the optical properties of quantum dots in nano-scale devices.

After a long period of interest of religious plurality in the nation-state, the sociology of religion, with the impulse of the sociology of migration, has turned its attention to the city. This local level allows us to understand the issues of diversity governance. This article takes advantage of the literature on the governance of migration to apply it to the governance of religious diversity. Using data from the National Congregations Study and available data on Geneva, this article will first show how past responses to the emergence of diversity determine the path for future decisions. To this top-down regulation of religion responds one or more bottom-up strategies of religious communities to find legitimacy in a constraining environment. Based on the unit of the religious community, this study on Geneva provides a historical case of the evolution of diversity. This historical perspective provides the consistency of the current governance of religious diversity, illuminating the struggle for recognition of the minority groups.


In wheat, semidwarfism resulting from reduced height (Rht)-B1b and Rht-D1b was integral to the 'green revolution'. The principal donors of these alleles are 'Norin 10', 'Seu Seun 27' and 'Suwon 92' that, according to historical records, inherited semidwarfism from the Japanese landrace 'Daruma'. The objective of this study was to examine the origins of Rht-B1b and Rht-D1b by growing multiple seed bank sources of cultivars comprising the historical pedigrees of the principal donor lines and scoring Rht-1 genotype and plant height. This revealed that 'Norin 10' and 'Suwon 92' sources contained Rht-B1b and Rht-D1b, but the 'Seu Seun 27' source did not contain a semidwarf allele. Neither Rht-B1b nor Rht-D1b could be definitively traced back to 'Daruma', and both 'Daruma' sources contained only Rht-B1b. However, 'Daruma' remains the most likely donor of Rht-B1b and Rht-D1b. We suggest that the disparity between historical pedigrees and Rht-1 genotypes occurs because the genetic make-up of seed bank sources differs from that of the cultivars actually used in the pedigrees. Some evidence also suggests that an alternative Rht-D1b donor may exist.


SVM has become the hot issue in the international machine learning field due to the excellent learning performance.Who is the author of "Dream of the Red Chamber" has not been come to an agreement.Many people have done more work for this problem and obtained different conclusions.This paper firstly uses the SVM method to compare the writing style between the former 80 sections and the last 40 sections of "Dream of the Red Chamber" and obtains the conclusion similar to the Refs.


Network parallel computing is a problem solving procedure that using diversified computing resources simultaneously. It is an effective ways to large calculation at present. In order to carry out network parallel computing, two basic conditions are required: network parallel computing system and MPI. The former provides the hardware platform and MPI is uniform programming environments for parallel program design. This paper elaborated the building process of a network parallel computing system from the following aspects: hardware , network setting, the configuration and using of MPI. An example is given to test the performance of the whole system. The results show that it is a better solving way to small-scale task.


Object spectral reflectance plays an important role in recognizing and discriminating object of interests from remote sensing images. It provides key recognition of objects for image classification purposes. This study aims to compare the effectiveness of radiometric calibration algorithms applied to Small Format Aerial Photography (SFAP) and WorldView-2 (WV-2) images with the closed-range field spectrometer measurement. Some dominant objects were selected as basis for spectral reflectance observation, this includes grass, nonmangrove vegetation, mangrove vegetation, soil, and asphalt. The SFAP and the WV-2 image were radiometrically corrected up to at-surface reflectance level. As reference, the spectral reflectance of selected objects was collected in the field using JAZ EL-350 spectrometer. To compare the spectral reflectance results, spectral resampling procedure was applied to the spectrometer measurement based on the center wavelength of each images to match up the spectral resolution of the images. The results showed that the pixel values of the SFAP and WV-2 corrections have similar pattern. This pattern shows that the radiometric/atmospheric correction applied to WV-2 and SFAP has been successful and they have equal capability in differentiating sampled objects.


Robots are generally required to help our everyday schedules particularly for tasks that are difficult to be done by us. The primary focus of the proposed project is to carry the load of 50 kg upwards the stairs. Then, the suitable of the microcontroller and the sensor of the robot is chosen to achieve the main objectives to be able the robot to carry the load on the stair. This project is divided into two sections which are software and hardware. There are two types of software that used in this project which is PROTEUS and Arduino. This software is using output and input to declare which pin low or high. This software can give command at pin input and output. We just select the pin that we want to the input and output. The hardware components that connect to the microcontroller are DC gear motor, gyro sensor MPU6050 and other components. It controls all the functions of the robot especially to control the motor speed during the robot is move. As the result from the purposed project, we had expected to build a very useful robot that is capable to carry 50kg load on rough surfaces and upwards and downwards stairs. We can conclude that with the help of the stair climbing robot, many people can use the robot to carry a heavy load upwards and downwards stairs. A more convenient and harmonic life can be achieved by using the stair climbing robot.

The goal of our study was to examine the hypothesis that exposure to 2, 3, 7, 8-tetrachlorodibenzo-pdioxin (TCDD) is associated with increase in CVD, and to determine whether this effect differs by gender. We have established a cohort of 323 former workers, who were engaged in the production of trichlorophenol (TCP), 2, 4, 5-trichlorophenoxyacetic acid (2, 4, 5-T) and 2, 4-Dichlorophenoxyacetic acid (2, 4-D), and the comparison group. Our data showed a positive association between TCDD exposure and angina, and atherosclerosis in men. The potential role of dioxin exposure as a preventable risk factor for CVD could be of substantial public and occupational health interest. Key words: Cardiovascular diseases (CVD), 2, 3, 7,  8-tetrachlorodibenzo-p-dioxin (TCDD)


Exhaled breath condensate (EBC) pH is a promising biomarker of airway inflammation. Lack of method standardization and interstudy variability precludes its use in clinical practice. While endogenous determinants have been described, underlying mechanisms for variability are mostly unknown. Thus, we aimed to assess the association between asthma and EBC pH in children, while studying potential environmental factors for interstudy variability.


In CPU, SOC, GPU, and PC-on-chip, I/O power consumption can be significant. To improve power efficiency, I/O bundles in group of 4, 8, or 16b, should scale their data rate according to the application requirements. However, clocking architecture imposes significant challenges to support different data rate simultaneously. In high bandwidth I/O, LC oscillators are preferred for low jitter, but the limited frequency range confines the data rate tuning. Multiple LC-PLLs are costly in area and power, and sometimes infeasible due to heavily congested I/O area. Worse still, couplings between inductors could lead to PLL pulling closing the sampling eye. In this paper, a reconfigurable 0.65–10GHz digital fractional-n clock generator using a single LC PLL, calibrated 0.75/1.25/1.75 digital fractional post dividers for serial I/O is presented. The architecture enables I/O driven by the same PLL to operate at different data rate, thereby reducing power. In addition, multiple LC-PLLs are replaced by one saving area, power, and coupling between LC oscillators. The PLL incorporates a staggered varactor, wide-tuning VCO, and a hysteretic redundant frequency acquisition for improved temperature stability. The prototype in a 32nm high-k metal gate process has a measured TX/RX jitter of 0.9/0.3 ps/σ and dissipates 36.2mW from 1.05V supply.


E CHO is familiar as a means to enhance music quality in concert halls, as a natural public address system in various ancient amphitheaters, and as a culprit (in the movies at least) for several romances and avalanches (though not necessarily in the same story). It plays a big role in telecommunications as well, and in this paper, we will discuss how and why echo cancelers are becoming the dominant means to control echo in the telephone system [1,2]. Echo in the telephone system is generally undesirable but .unavoidable. Consider a typical toll call (Fig. 1) in which the transmission medium is a satellite link instead of wires. The local link from phone to central office is a bidirectional "two-wire" loop while the satellite link uses two separate unidirectional channels for "four-wire" transmission. The use of separate channels for the two directions of transmission is a necessary characteristic of long distance transmission links. The conversion between the two-wire and four-wire parts of the overall transmission link is done in the device called a "hybrid". Ideally, a hybrid circuit couples all energy on the incoming branch of the four-wire circuit into the two-wire circuit, and none of the incoming four-wire signal should be transferred to the outgoing branch of the four-wire circuit. The hybrids do not operate perfectly, however, because of impedance mismatch problems. As a result, some energy on the in-


KM3NeT is a network of submarine Cherenkov neutrino telescopes under construction in two different sites in the Mediterranean Sea [1]. The detector at the Italian site, close to the Sicilian coast and named ARCA, will be devoted to the detection of high-energy astrophysical neutrinos coming from sources in the Universe, while the detector at the French site, in the Toulon bay and named ORCA, will exploit atmospheric neutrinos to determine the neutrino mass hierarchy. The telescopes are an array of flexible strings anchored to the sea floor and held close to vertical by submerged buoys. The strings are instrumented with digital optical modules hosted within pressure-resistant glass spheres, each housing 31 3" photomultipliers tubes and the readout electronics. The geometry of the detectors has been adapted to their physics goals. The first calibrations and results of ARCA and ORCA are presented.

Alveolysis is an asymptomatic and infrequent condition. It occurs when the root of the tooth becomes susceptible to the presence of biofilm and formation of calculi, preventing the process of spontaneous wound healing, causing inflammation and irritation of the surrounding mucosa. The main causes of alveolysis are dental caries and dentoalveolar trauma. In the treatment of alveolysis, immediate exodontia is usually indicated. The present study aims to present a case report of a 5 - year - old female child with alveolysis of primary tooth 51, which was extracted and showed a normal healing process with eruption of successor tooth 11 without alterations. It is up to the dentist to search for information about this pathology, knowing how to identify it and treat it early to significantly improve the child's quality of life.


Abstract : A three-node single-loop intrusion detection system was constructed and set up in a laboratory at GRC's McLean facility. A sensor field containing RACON, MILES, and SPIR sensors, as well as several geoplanes, was installed by WES at that facility, and the sensors were connected to the system so that test data could be collected and the performance of the system measured. The pattern classifier (Adaptive Learning Network or ALN) used in the system was originally trained on data collected at Eglin Air Force Base. With that ALN in the system, tests were run at GRC. During the testing, the system maintained a Pd of .974 and a Pna of .070 where large dogs, approximately human weight, were primarily used as nuisances. Keywords: Intrusion; Retrain; Loopback; Nuisance Alarm; Poll.

This article examines the problem of the status of the different degrees of being that Plato, in the Timaeus, seems to attribute to the different kinds of reality that he distinguishes. In what sense and under what conditions is it possible to state that the intelligible forms, the sensible things and the spatial and material substratum of the chora "are" and "exist" ?


The distinctive features of modern reality are the growing dynamism and globalization, economic crises and shocks, increasing environmental pressure and depletion of natural resources, social vulnerability and stratification, natural disasters and hazards. The world is becoming less predictable, and risk events that cannot be quantified a priori are becoming the norm. Under these conditions, the leading organizations all over the world pay great attention to study of the global risk. The article describes the evolution of the term "economic risk" and conducts its semantic analysis, clarifies the concepts of global risk and global risk factors, complying with ISO-31000 international standards of risk management. Based on the analysis of reports and program documents of the World Economic Forum, the International Monetary Fund and the World Bank, the approaches of international organizations to the study of global risk and the reasons for their discrepancies have been specified. We have considered risk factors regarded as the most important ones from the point of view of international organizations, as well as the main program documents related to the consideration of risk factors, the identification and study of the relationship between the concepts of sustainable development and modern approaches to the analysis of global risk. Based on the World Economic Forum reports from 2008 to 2019, a dynamic analysis of the enlarged categories of global risk (economic, environmental, geopolitical, social, and technological) have been carried out in terms of the likelihood of occurrence and in terms of the significance of the consequences. A qualitative analysis of the TOP 10 global risks has been carried out and trends and reasons for their change have been identified. The features of environmental and technological risks of the digital economy have been analyzed.


Let Μ c C" (« > 2) be a real analytic hypersurface that has at all points a non-degenerate Levi form, that is, one locally given in the form ν = (ζ, z) + F(z, ζ, u); here ζ = (z l t . . ., zn_i)and w = u + iv are coordinates in C"; F is a real analytic function such that F(0) = 0, rfF(O) = 0 and d"-F — (0) = 0 ; <z, z> is a non-degenerate Hermitian form, called the Levi form of M. We denote dzjPzk by cy(.M)the stability group of Μ at the point ζ = 0, w = 0, that is, the group of transformations that are biholomorphic at the origin, map Μ to itself, and leave the origin fixed. If Μ is the quadric υ = (ζ, z>, then, as was proved by Poincare [2] and Tanaka [3], all the elements of its stability group turn out to be linear-fractional (and in projective coordinates, linear) transformations of a certain special form. Vitushkin in [1] posed the question of the linearization of the group ^P(AJ) in the case of a nonspherical surface Μ (not locally equivalent to a quadric). If Μ is strictly pseudo-convex (that is, its Levi form is positive definite) and, in addition, non-spherical, then its stability group is compact (Vitushkin [4]), and in some normal coordinates all the elements of the group can be represented in the form z* = Uz, w* = w, where U is a unitary matrix (Kruzhilin and Loboda [5]), (for the definition of normal coordinates see [6]). For hypersurfaces in C 3 whose Levi form has one positive and one negative eigenvalue, it was proved in [7] that it is possible to linearize the stability group. In this note we generalize the result of [7] as follows: Theorem. Let Μ c C (n > 3) be a non-spherical real analytic hypersurface whose Levi form has exactly one negative eigenvalue. Then in certain normal coordinates all the elements of af(M) can be written in the form z* = \Uz, w* = σλνν, where U is a matrix of dimension n-\ such that (Uz, Uz) = σ(ζ, ζ), σ = ±1, λ > 0.


Diesel emission control is being addressed worldwide to help preserve the global environment. This paper mainly deals with the effects of oxidation catalysts to reduce emissions from the automotive heavy-duty diesel engine. Two types of the oxidation catalyst with different kinds of precious material were used. An 11 litter displacement diesel engine with turbocharger was operated to evaluate DOC with various engine speed, load conditions under D-13 mode cycle. We could propose the detail emission data of an automotive heavy-duty diesel engine and the characteristics of the conversion efficiency of the DOC under the D-13 mode. It was found that the mean conversion efficiencies of CO and THC were 49.7% and 61% under the D-13 mode test, respectively.


In the study we focus on determining the contents of artemisinin in Artemisia annua L. from different geographical origins of southwest district of China. The artemisinin contents of eleven samples are measured by the high performance liquid chromatography (HPLC). As a result, Artemisinin exists in different parts of A. annua plant and the content is as follow: inflorescences > leaves > stems. Except for the material from Qianjiang district, Artemisinin content of four materials in Chongqing area is higher than those of Sichuan and Guizhou by the average of 0.728%. We conclude that the artemisinin contents of A. annua, collected from Sichuan and Guizhou province, do not reach the value of industrial development, while the others can


In this data world, where users spawn their digital footprint and generate a huge amount of unstructured data continuously with each activity, data mining techniques help in discovering interesting patterns, establishing relationships and unravel the problems through analysis, in different aspects of life. Educational data mining is a multidisciplinary research area, in which data from various educational organizations, is explored and made operational, for various facets concerned with the students, like predicting academic performance, analyse the learning pattern, solving e-learning issues, predict employability, visualize the critical courses affecting performance, investigate the reasons for student's failure or drop out and thus make data-driven decisions to improve the institutions standards. This paper provides a brief overview of Data Mining tools and techniques, and its encroachment in the educational domain. It also proposes a simple framework using different variables which helps in predicting student's academic success using two different algorithms: Decision Trees and Bayesian Network. Finally, a comparative analysis of accuracy is done. The results show that Bayesian Network outperforms the Decision Tress and gives better accuracy.

In the farming process, often used conventional seeding operation takes more time and more labor. The seed feed rate is more but the time required for the total operation is more and the total cost is increased due to labor, hiring of equipment. The conventional seed sowing machine is less efficient, time consuming. Today's era is marching towards the rapid growth of all sectors including the agricultural sector. To meet the future food demands, the farmers have to implement the new techniques which will not affect the soil texture but will increase the overall crop production. Agriculture in India has a significant history. Today, India ranks second worldwide in farm output. Still, agriculture is demographically the broadest economic sector and plays a significant role in the overall socio-economic fabric of India.


The liquid medium ingredients of entomopathogenic nematode symbiotic bacteria strain 5-5B was studied for cheaper and compatible for large-scale production by the quadratic rotation-orthogonal regressive combination design.The results showed that the production of bacteria was affected mostly by corn starch in all component of the medium.The best horizontal code value of five ingredients were 0,1,2,1,-2;which meant that the five ingredients were corn starch,soybean powder,yeast,fish meal and peptone,content for 3.0,2.0,2.5,2.0 and 0.1 g·(100mL)-1 corresponding.Over all the optimal formula of the liquid medium could be used to large-scale production.


The place occupied in cultural memory by the First World War is chiefly determined by a handful of mainly English-speaking poems which portray the conflict as a senseless slaughter. During the war itself, opinion was strongly influenced by a film made for the propaganda arm of the British war effort: The Battle of the Somme (1916), which managed to elicit quite varying reactions. The violence of war had never before been brought into focus so sharply, yet the interpretations of this mediated reality were varied. Three poets wrote about, what of necessity, remained absent from this silent film: the noise of industrial warfare (imitated in some performances by live musicians) and the voice of the individual soldier. Jingoist Henry Newbolt saw the film as an ode to sacrifice, while his compatriot and Somme veteran C.H.B. Kitchin was chiefly struck by the fact that so many soldiers only lived on on celluloid. In neutral Holland Jacobus van Looy was confronted with his own search for excitement and half-hearted humanity.


Recent interest to the Hall viscosity in the theory of Fractional Quantum Hall effect (FQHE) and the interest to the interplay of defects and mechanical stresses with electromagnetic properties of materials motivates studies of gravitational, electromagnetic and mixed responses in condensed matter physics. Gravitational field in condensed matter systems can be understood either as a way to represent deformational strains present in the material under consideration or as a technical tool allowing to extract correlation functions involving stress tensor components. It is always important to have a simple model system for which such responses can be calculated exactly. For the quantum Hall effect one can consider two-dimensional electron gas in a constant magnetic field (2DEGM) as such a model. When the density of fermions is commensurate with magnetic field the integer number of Landau levels is filled and one expects local and computable response to weak external fields. This model is as important starting point of analysis for quantum Hall systems as a free electron gas for the theory of metals. However, while some electromagnetic responses for 2DEGM can be found in literature we were not able to find the complete results for mixed and gravitational linear responses. The goal of this paper is to compute these responses providing the analogue of Lindhard 1 function, both e/m and gravitational, for 2DEGM. We compute the effective action encoding linear responses in the presence of external inhomogeneous, time-dependent, slowly changing electromagnetic and gravitational fields. We compare and find an agreement of the obtained responses with known e/m responses 2–5 and with known results for Hall viscosity at integer fillings 6,7 . In addition we find the stress, charge and current densities induced by spatial curvature. Another point of comparison is given by phenomenological hydrodynamic models for FQHE 8–13 and Ward identities following from the exact local Galilean symmetry (also known as non-relativistic diffeomorphism) of the model 14,15 . The paper is organized as follows. In Section II we describe the model as a non-relativistic quantum field theory and present our results in terms of the effective action. In Section III we extract the electromagnetic responses from the effective action. We demonstrate some peculiar physical effects such as charge accumulation/depletion in the presence of conic singularity in metric, non-dissipative current perpendicular to a gradient of curvature and report higher gradient corrections to Hall conductivity. Our main results are presented in the Section IV where we discuss the gravitational responses. We present higher gradient and dynamic corrections to Hall viscosity. We leave the in-depth discussion of dynamic responses and their relation to the local Galilean invariance for a separate publication.


Many natural and synthetic cancer chemopreventive compounds are potent inducers of phase II detoxifying and antioxidant stress responsive genes. The phase II/antioxidant gene expression plays critical role in chemoprevention of carcinogenesis. The antioxidant responsive element (ARE), located on many phase II/antioxidant genes, binds with the transcription factor Nrf2, and is required for the activation of these phase II/antioxidant gene expression induced by many natural and synthetic cancer chemopreventive compounds. In this study, we investigated the potential roles of extracellular signal‐regulated kinase (ERK) and c‐jun N‐terminal kinase (JNK) in the regulation of butylated hydroxyanisole (BHA)‐induced and Nrf2‐dependent ARE transcriptional activity and ARE‐mediated endogenous heme oxygenase‐1 (HO‐1) protein expression in HepG2 cells. ARE transcriptional activity and HO‐1 protein expression were increased dose dependently after treatment with BHA in HepG2 cells. Dose‐response and time‐course experiments showed that BHA increased the accumulation of Nrf2, and concomitantly decreased the protein level of Keap1. We next examined the phosphorylation of the MAPKs, and found that BHA significantly increased the phosphorylation levels of ERK1/2 and JNK1/2. Importantly BHA‐induced ARE transcriptional activity was attenuated by the inhibition of ERK and JNK signaling using biochemical inhibitors and their dominant‐negative mutants. Using confocal microscopy technique, treatment with BHA showed the release of Nrf2 sequestered by Keap1 in the cytosol, and that Nrf2 translocated into the nucleus. Importantly, cDNA transfections of ERK and JNK signaling pathways similarly released Nrf2 from Keap1 cytosolic sequestration and translocating Nrf2 into the nucleus. Taken together, these results strongly suggested that ERK and JNK signaling pathways played important and positive roles in BHA‐induced and Nrf2‐dependent regulation of ARE‐mediated gene expression, as well as the nuclear translocation of Nrf2 in HepG2 cells. © 2006 Wiley‐Liss, Inc.

The shrike, which is a common Indian bird, was noticed by ancient Indians. This is a brief treatise on some references to the shrike in ancient Indian texts, written in the Sanskrit language. Original Sanskrit verses are deliberately mentioned in this brief communication. The knowledge of Sanskrit language, a true window to the ancient Indian knowledge and culture, can thus give a modern reader a delightful and mesmerizing experience of serious avian observations from ancient India. There are numerous references to birds in the Sanskrit literature. Many birds can be traced back to 2500 BC. However, it is often difficult to exactly identify the particular species mentioned in the ancient literature if no proper description of the bird is available. In such cases, one may allot the ancient name to a particular present- day bird, basing on its name, if the name describes a peculiar habit of the bird. In other cases, one has to go back from the present name of the bird, analysing step by step the derivation of the present name from the earlier versions, in accordance with the rules of grammar, until one arrives at the root word in the Sanskrit language. This is often a tedious process and sometimes may be unsuccessful, as a particular name may remain ambiguous and one has no option but to let it remain so. Only rarely the task is easy because the ancient name is retained till the present day. Fortunately, we have a reliable present-day Sanskrit derivation of the name for the shrike. Many Indian languages have evolved from the parent Sanskrit language. One of these languages is Marathi, the regional language of the Maharashtra state. It is in this language that a few peculiarly descriptive names for the shrike are mentioned, viz. Khatik (the butcher) or Naklya Khatik (the butcher who mimics). Another name, which has a special reference to one of the popular ancient Indian epics, is Gand- hari. The epic is the eMahabharatai, the longest poem in any language, and Gand- hari is the name of the blind-folded Kaurava Queen. She chose to wear a mask over

The interactions between charged colloidal particles in an electrolyte may be described by usual Debye−Huckel theory provided the source of the electric field is suitably renormalized. For spherical colloids, we reconsider and simplify the treatment of the popular proposal put forward by Alexander et al. (J. Chem. Phys. 1984, 80, 5776), which has proven efficient in predicting renormalized quantities (charge and salt content). We give explicit formulas for the effective charge and describe the most efficient way to apply the renormalization prescription of Alexander et al. in practice. Particular attention is paid to the definition of the relevant screening length, an issue that appears to be confused in the literature.


In software-defined networking (SDN), the control layers are moved away from the forwarding switching layers. SDN gives more programmability and flexibility to the controllers. OpenFlow is a protocol that gives access to the forwarding plane of a network switch or router over the SDN network. OpenFlow uses a centralized control of network switches and routers in and SDN environment. Security is of major importance for SDN deployment. Transport layer security (TLS) is used to implement security for OpenFlow. This paper proposed a new technique to improve the security of the OpenFlow controller through modifying the TLS implementation. The proposed model is referred to as the secured feedback model using autoregressive moving average (ARMA) for SDN networks (SFBARMASDN). SFBARMASDN depended on computing the feedback for incoming packets based on ARMA models. Filtering techniques based on ARMA techniques were used to filter the packets and detect malicious packets that needed to be dropped. SFBARMASDN was compared to two reference models. One reference model was Bayesian-based and the other reference model was the standard OpenFlow.


Two commercial-o ff -the-shelf (COTS) 4H-SiC UV photodiodes have been investigated for their suitability as low-cost high temperature tolerant X-ray detectors. Electrical characterisation of the photodiodes which had di ff erent active areas (0.06 mm 2 and 0.5 mm 2 ) is reported over the temperature range 0 °C to 140 °C together with measurements of the X-ray photocurrents generated when the detectors were illuminated with an 55 Fe radioisotope X-ray source. The 0.06 mm 2 photodiode was also investigated as a photon counting spectroscopic X-ray detector across the temperature range 0 °C to 100 °C. The depletion widths (at 120 V reverse bias) of the two diodes were found to be 2.3 µm and 4.5 µm, for the 0.06 mm 2 and 0.5 mm 2 detectors respectively, at 140 °C. Both devices had low leakage currents (<10 pA) at temperatures ≤ 40 °C even at high electric fi eld strengths (500 kV/cm for 0.06 mm 2 diode; 267 kV/cm for 0.5 mm 2 diode). At 140 °C and similar fi eld strengths (514 kV/cm for 0.06 mm 2 diode; 269 kV/cm for 0.5 mm 2 diode), the leakage currents of both diodes were < 2 nA (corresponding to leakage current densities of 2.4 µA/cm 2 and 0.3 µA/cm 2 for each diode respectively). The results demonstrated that both devices could function as current mode detectors of soft X-rays at the temperatures <80 °C and that when coupled to a low noise charge sensitive preampli fi er, the smaller diode functioned as a photon counting spectroscopic X-ray detector at temperatures ≤ 100 °C with modest energy resolution (1.6 keV FWHM at 5.9 keV at 0 °C; 2.6 keV FWHM at 5.9 keV at 100 °C). Due to their temperature tolerance, wide commercial availability, and the radiation hardness of SiC, such detectors are expected to fi nd utility in future low-cost nanosatellite (cubesat) missions and cost-sensitive industrial applications.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the virus responsible for COVID-19 has infected more than 25 million Americans, leading to over 420,000 deaths.1 The Centers for Disease Control and Prevention (CDC) reports over 378,000 cases of COVID-19 in US health care personnel (HCP) with 1,286 deaths.2 By summer 2020, an estimated 4.6% of academic emergency department (ED) HCP had contracted COVID-19.3 In mid-December 2020 Emergency Use Authorization COVID-19 vaccines were administered to US HCP as a priority group. The objective of this report is to describe differences in vaccination rates among various types of ED HCP at US academic medical centers and reasons for declining vaccination. We hypothesized that groups of ED HCP with differences in workplace risks might view the benefits of vaccine differently and that vaccine hesitancy would higher in people of color.

Abstract An account of the demand and provision for courses in robotics at sub-degree level in the 1980s. The basic hypothesis, that there is a mismatch between training needs in robotics, and the supply of courses to meet those needs, is examined by means of a survey of robot users, suppliers and courses in Colleges of Further Education in England and Wales. There was found to be a mismatch between demand and supply. The problems of developing the supply of courses to match the demand for such courses is examined, with the need to keep up-to-date with developments of robotics in the industry and commerce.


Abstract : To support its 172 medical centers and outpatient clinics, the Department of Veterans Affairs spent nearly $1.3 billion in FY91 on drugs and pharmaceuticals, medical supplies, and nonperishable subsistence. In that year, the distribution cost the VA $138 million, nearly $11 out of every $100 spent for medical material. Much of the expense of the VA's material support system is caused by its large inventories, especially in the medical centers. Recent improvements by the VA (use of Prime Vendor distributors and faster service from the supply depots) have begun to reduce those inventories, but more can be done to reduce the system's costs and improve its responsiveness. This report describes the current VA material distribution system and explains our approach, based on the identification of customer needs, for developing network alternatives. We define a composite measure of customer service, called average system response time (ASRT), and present six alternative material support strategies - each designed to satisfy ASRT - ranging from a consolidated 'Super Depot' with regional distribution centers to total reliance on commercial sources. We then model four of those alternatives (and several variations of them) to determine their costs. We recommend that the VA rely more on direct support, not inventories, to satisfy its medical material needs. To permit it to close the medical center warehouses, it should establish more direct support contracts and, in the short run, expedite all requisitions from its supply depots....

The use of succinylcholine(SC) in burn patients arerelatively contraindicated for certain period after lesion aged4 days – 10 weeks due to chance of hyperkalemia althoughthere are no systemic data to define what period and whatlevel of K+ is safe. This prospective study was carried out in60 acute burn patients who were admitted in DMCH BurnUnit and undergone surgery within 3 months of lesion. Mostcommon type of burn was flame burn (33%).Mean age ofthe patient was 22.60 ± 9.61, TBSA (Total burn surface area)was 22.17 ± 9.57 and duration of burn was 23.36 ± 19.61.Every patient received standard dose of SC (1.5mg/kg) forintubation. The peripheral venous blood samples for serumK+, Na+, Cl - & HCO3- were drawn before induction and 3minutes after injection of SC. On analysis there were nosignificant change of serum K+ and HCO3- (p > .05), on theother hand serum Na+and Cl- levels were significantlychanged (p<0.05) due to correction of dehydration. In caseof electric burn serum K+ level was raised in every casesbut didn't cross the normal high level of serum K+ (5.5mEq/l). Haemodynamic parameters like pulse, NIBP, SPO2 andECG were analyzed intra operatively and there were nosignificant change in NIBP and ECG, rather there weresignificant improvement in pulse and SPO2 (p< 0.05).Survival of anaesthetic was 100% and no dysrhythmias ormajor morbidity were found intra operatively. Therefore,these data taken in the context of a compelling case forrapid intubating condition suggest safety in succinylcholineuse in the patients with acute burn.

In 1983, Huntington's disease (HD) was the first genetic disease mapped using DNA polymorphisms. Shortly thereafter, presymptomatic genetic testing for HD began in the context of two research studies. One of these trials was at the Johns Hopkins University Huntington's Disease Center.


Background Oral candidiasis still has high prevalence and frequently causes problems in the neonatal period. Objective To evaluate some factors associated with the occurrence of oral Candida colonization in neonates. Methods A cross sectional study was performed at the Intensive Care Unit, Neonatology Division, Department of Child Health, Medical School, Udayana University/Sanglah Hospital Denpasar, from November 2002 to April 2003. Eighty neonates were enrolled. Oral mucous swabs were obtained and examined for Candida colonization using potassium hydroxide (KOH). Data were analyzed by prevalence ratio and logistic regression; a p value of 1 week, male sex, gestational age of <37 weeks, Apgar score of <7, birth weight of <1500 grams, oral mucous pH of <7, systemic antibiotic use, and steroid use by mother. Breastfeeding was a protective factor. Correlation between variables using Spearman test revealed correlation coefficient of <0.5. By logistic regres- sion, birth weight of <1500 grams (p=0.04) and systemic antibi- otic use (p=0.01) were significant associated factors of oral Candida colonization, while breastfeeding was a significant pro- tective factor (p=0.03). Conclusion Birth weight of <1500 grams and systemic antibiotic use were significant associated factors of oral Candida colonization and breastfeeding was a significant protective factor of oral Candida colonization in neonates


Abstract. We present a multi-year short-range hindcast experiment and its experiment procedure for better evaluating both the mean state and variability of atmospheric moist processes in climate models from diurnal to interannual time scales to facilitate model development. We use the Community Earth System Model version 1 as the based model and performed a suite of 3-day long hindcasts every day starting at 00Z from 1997 to 2012. Three processes – the diurnal cycle of clouds during different cloud regimes over the Central U.S., precipitation and diabatic heating associated with the Madden-Julian Oscillation propagation, and the response of moist processes to sea surface temperature anomalies associated with the El Nino-Southern Oscillation – are evaluated as examples to demonstrate how one can better utilize simulations from this experiment design to gain insights into model errors and their connection to physical parameterizations or large-scale state. This is achieved by comparing the hindcasts with corresponding long-term observations for periods based on different phenomena. These analyses can only be done through this multi-year hindcast approach to establish robust statistics of the processes under well-controlled large-scale environment. Furthermore, comparison of hindcasts to the typical simulations in climate mode with the same model allows one to infer what portion of a model's climate error directly comes from fast errors in the parameterizations of moist processes. As demonstrated here, model biases in the mean state and variability associated parameterized moist processes usually develop within a few days, and manifest within weeks to affect the simulations of large-scale circulation and ultimately the climate mean state and variability. Therefore, model developers can achieve additional useful understanding of the underlying problems in model physics by conducting a multi-year hindcast experiment.

—Patterns are a methodology for capturing best practices and solutions to reoccurring problems in certain fields or disciplines. Applied to automotive interaction design they can combine empirical data, industry knowledge, and experts experience for state-of-the-art design solutions. In this paper, we present the patterns approach and its application to the automotive interaction domain, together with a newly generated set of eight in-vehicle user experience (UX) design patterns that describe answers to problems in automotive interaction design and engineering. These patterns are part of an ongoing project with the aim of providing a comprehensive, user experience focused, collection of design solutions for contemporary and future automotive designs. We present the pattern approach in general, the specific automotive approach and methodology, the patterns themselves, and finally discuss the benefits, drawbacks, and future work regarding patterns in the automotive domain.


KOR: An ABSTRACT It has been widely observed that the pattern of dissenting and oppositional activity in Poland had changed considerably by the early 1980s. While in the 1950s and 1960s it was characterised by spontaneity, lack of programme and strategy, the opposite holds true in the 1980s. Till the second half of the 1970s dissent in Poland was spasmodic and short‐lived, intertwined with relatively long periods of social calm and inactivity. In the mid‐1980s the Poles have become highly politicised people, the previously common political apathy, to a great extent, has disappeared. Clandestine political organisations, inimical towards the communist state, abound. The number of free, uncensored publications can be counted in hundreds if not thousands. In the early 1980s there existed officially in Poland a free trade union which in fact performed some political activity as well. For this and other reasons it was suppressed, however the struggle to restore its official activity continues. Nothing of that n...


Quality parameters at harvest, and color, ethylene production (EP) and headspace volatile production rates during postharvest ripening at 20C were investigated on two Golden Delicious-like scab-resistant apples (Golden Orange [GO] and Golden Lasa [GL]), and on the scab-susceptible Golden Delicious clone B (G) cultivar. At harvest, quality parameters defined GO and GL apples as less mature than G ones, even if their skin color was yellower. With postharvest ripening, GO and GL apples showed lower EP, lower maximum total volatile production, and their skin color turned as yellow as G ones. When fully mature, GO and GL differed from G apples for organic acid, sugar and volatile compositions, which could explain the different sensory descriptions particular to these cultivars. Canonical discriminant analysis showed that the differences in volatile composition among the three cultivars became greater as the postharvest ripening process went on, and, only when fruits were still immature, could cultivars not be distinguished by using the aroma pattern.


I examine whether federal intergovernmental grants have a persistent long-term effect on state fiscal policy. A simple theoretical framework is developed based on the median voter model and is structurally estimated based on a 30-year panel of U.S. federal grants and state tax revenues. In both OLS and IV estimates I find evidence that temporary federal aid has a persistent effect on state finances. Each $1 of federal grants predicts eventual state tax increases of between $0.04 and $0.17. These effects are most evident on state personal income and corporate income taxes. There is some evidence that state tax and expenditure limitations (TELs) and supermajority voting rules mitigate these effects. To address possible endogeneity of federal grants I employ an instrumental variables strategy which yields similar results. Consistent with previous literature I find state budgets respond asymmetrically with respect to increases and decreases in federal grants, with temporary grant-funded expenditures persisting over time in state budgets.


The mammalian (or mechanistic) target of rapamycin (mTOR) complex 1 (mTORC1) is a serine and threonine kinase that regulates cell growth, survival, and proliferation. mTORC1 is a master controller of the translation of a subset of mRNAs. In the central nervous system mTORC1 plays a crucial role in mechanisms underlying learning and memory by controlling synaptic protein synthesis. Here, we review recent evidence suggesting that the mTORC1 signaling pathway promotes neuroadaptations following exposure to a diverse group of drugs of abuse including stimulants, cannabinoids, opiates, and alcohol. We further describe potential molecular mechanisms by which drug‐induced mTORC1 activation may alter brain functions. Finally, we propose that mTORC1 is a focal point shared by drugs of abuse to mediate drug‐related behaviors such as reward seeking and excessive drug intake, and offer future directions to decipher the contribution of the kinase to mechanisms underlying addiction.


The ODP Enterprise Language is used to describe the organizational objectives and policies that apply to some system to be specified. It also captures constraints associated with the environment in which the system is to be used. Because the enterprise specification is concerned more with organizational issues than technical details of the system, there is considerable emphasis on obligations and norms, rather than on the declaration of some single rigidly required behaviour. The recently revised Enterprise Language is already able to express directly obligations and other deontic concepts, such as permissions and prohibitions. However, mapping such concepts into UML offers interesting challenges. This paper describes work currently in progress within the International Organization for Standardization (ISO) to extend the UML4ODP standard ISO/IEC 19793 for dealing with deontic concepts, and illustrates the approach with a simple case study.


Attention to form has been shown to be a direct predictor of accuracy in second language (L2) production (Ellis, 1987; Tomlin & Villa, 1994). However, Tarone and Parrish (1988) claim that communicative pressure (communicative demands of linguistic interaction) may be as important as attention to form. The present study analyzes the accuracy of L2 Spanish production across 3 different tasks (narrative task, multiple-choice cloze test, and fill-in-the-blanks cloze test) on 3 discourse-determined grammatical items (subject pronouns, articles, and past tense aspect) among 74 native (L1) English speakers (45 intermediate and 29 advanced students). The analysis of the data reveals different rates of accuracy in L2 production according to task type and grammatical item. The effect of functional focus on form (communicative pressure) may constitute one of various factors that affect accuracy in L2 production. The analysis of the data also considers other factors such as communicative control.


The analysis of studies on the problem of the formation of a new economy with the use of convergent (NBIC) technologies is carried out. The prevalence of overestimated expectations from the use of technologies of the 5th and 6th modes in the developed spheres of social systems activity was established, while ignoring or underestimating the possible negative consequences of their implementation. The necessity of implementing the concept of intellectual support in the activities of economic and social systems, including the components of predetermination, validity, permanence, adequacy, which form the prerequisites for the purposeful creation of intelligent products of a given functional purpose for all stages of the life cycle of innovative products, is shown.


This research main on direct growth of oriented Mg–Fe layered double hydroxide (Mg-Fe LDH) film on the surface of SUS-316L. According to the polarization test, to investigate the Mg-Fe LDH film could enhance the corrosion resistance. Corrosion current density (I(corr)) of the Mg-Fe LDH film in aqueous 0.85M H2SO4 was lower than raw materials (SUS-316L) obviously. The sample was bubbling CO2 into solution at the pressure of 4.0 kPa and the corrosion current density was less than 1.0μA/cm2. It shows the film caused the sample of the Mg-Fe LDH film on SUS-316L has much more corrosion resistance. In addition, this research also investigate that growth of the Mg-Fe LDH sheet structure were affected by controlling the pressure of bubbling CO2 into solution.The picture of the Scaning Electron Microscope (SEM) exhibited that the area of the sheet structure of the Mg-Fe LDH was as larger as the pressure of the bubbling CO2 was higher. After the sample were test in the slat-fog during 60 days,there were no any erode or partial peeling in Mg-Fe LDH sheet structure. The cross-cut tape test for testing the adhesion of the Mg-Fe LDH film on SUS-316, none of the square of the lattice were detached. According to ASTM D3359 standard, the result was ranked as 5B and it was suggested that the Mg-Fe LDH coating adhered excellently on the surface of the SUS-316L.


This study investigated the prevalences and intensity of intestinal parasites and aspects of their epidemiology among children in the Qwa-Qwa region of the eastern Free St~te. Faecal samples of 1180 children differing socio-economic status from nine schools at altitudes varying from 1660m to 2200m were examined quantitatively by means of the formol-ether sedimentation technique. Socio-economic, and demographic characteristics for the communities served by the schools were obtained from the literature and from a questionnaire. The study showed that, the area supports a markedly low diversity of parasite infections, and at lower intensities, than lowaltitude areas such as the coastal plain of KwaZulu-Natal and Eastern Cape, the Northern Province, Mpumalanga and the Western Cape. The intestinal parasite fauna affecting children in Qwa-Qwa is dominated by protozoans with only few helminths and no hookworm or bilharzia. The results indicated that factors which influence the transmission of intestinal parasites in Qwa-Qwa appear to be related primarily to social, economic and cultural aspects of the peoples' lifestyles. Climatic factors were not found important. There was a significant seasonal effect on the intensities of all parasite infection, except two protozoans, Entamoeba coli and Endolimax nana.


The American Statistical Association's primary founder, Lemuel Shattuck, was driven by a passion for collecting and disseminating accurate information on vital statistics, public health, and other statistically related concerns. The 175th anniversary provides an opportunity to reflect on the education-related reasons ASA was founded and what it has done in education since its founding, especially in the past 25 years since the 150th anniversary. An examination of early and more recent issues of the ASA's journals reveals some common themes that have recurred over the past 175 years. We discuss what those themes are and what the ASA is doing to address them currently, and then conclude by discussing what ASA members can do to help.

On the other hand Beclere (I!KU & IMS a, b & c) and Huffmann (1942) speak of functional uterine haemorrhage due to genital infection. Brewer and Jones (1948) say that although most authors include under this designation onlv those cases in which there is 110 associated gross pel\ ic pathology, they believe that it can occur irrespective of the presence or absence of gross pelvic pathology and that the ovarian and endometrial changes are identical in each case. Smith (1944) is of the opinion that


Monocular 3D object detection attempts to predict object location and dimension in 3D space using a single optical camera. The main challenge of monocular 3D object detection is the lack of depth information to infer the object's distance. In this work, we propose a monocular 3D object detection based on CenterNet with discrete depth and encoded orientation angle. Our proposed method is able to achieve 54.6% detection score for car class on the challenging Cityscapes autonomous driving dataset, outperforming prior monocular 3D object detection by a convincing margin.
