The calculation of Young's moduli of short fiber reinforced composites based on the Elementary Volume Concept (EVC) assumes that they are defined by the properties of the elementary volume. The elementary volume contains a single fiber having equal spacing to all neighboring fibers. For good fiber matrix adhesion one obtains aspect ratio dependent Young's moduli parallel and perpendicular to the fiber axis without any fitting parameters. For highly oriented quasi unidirectional short fiber reinforced composites as manufactured by push pull processing, the calculated and measured Young's moduli agree quite well. However, distinct differences occur in the case of conventionally processed short fiber reinforced composites with low preferential fiber orientation.

The electromagnetic stirring (EMS) in the continuous casting mould is an effective technique of improving the inner and surface quality of steel blooms and slabs by means of electromagnetic force to intensive fluid flow and heat/mass transfer in the solidification process of steel. In this paper, the numerical simulation of electromagnetic field and fluid flow in a continuous casting mould of steel bloom was carried out to investigate the behavior of fluid flow under different process parameters. First, the influence of EMS structure parameters on the distribution of magnetic induction intensity and electromagnetic force were simulated and is verified with the measured values in metallurgy factory. The results show that the magnetic induction intensity and electromagnetic force reaches to maximum in the center of EMS. The different proportion of pole and yoke has little effect on the distribution of magnetic induction intensity and electromagnetic force in the center line of outer surface. The numerical simulation of 350 mm × 470 mm bloom show that all of the magnetic induction intensity, electromagnetic force, velocity, turbulence kinetic energy, and turbulence kinetic energy dissipation are increase with the electric current. However, the magnetic induction intensity is decreased as the increases of electric power frequency. Without EMS, most of inclusions in the mold downflow directly to the outlet of mold with melt steel which will bring some defects in the bloom. Using applied EMS, the inclusions in the melt steel do rotating motion with molten steel, and more and more inclusion particles accumulate to the upper zone of mold when the electric current increases, so that the removal rate of inclusion particles in the mold will increase and the internal and subsurface quality of bloom is improved.


In this study optimal linear estimators of missing values for bilinear time series models BL (p, 0, p, p) whose innovations have a student-t distribution are derived by minimizing the h-steps-ahead dispersion error. Data used in the study was simulated using the R Statistical Software where 100 samples of size 500 each were generated for the bilinear model BL (1, 0, 1, 1). The time series data generated was numbered from 1 to 500. In each sample, three data positions 48, 293 and 496 were selected at random and the value at these points removed to create artificial missing values. For comparison purposes, two commonly used non-parametric techniques of artificial neural network (ANN) and exponential smoothing (EXP) estimates were also computed. The performance criteria used to ascertain the efficiency of these estimates were the mean squared error (MSE) and Mean Absolute Deviation (MAD). The study found that ANN estimates were the most efficient for estimating missing values of the bilinear time series with student-t innovations. The study recommends the use of ANN for estimating missing values in bilinear time series model with student errors.


We present sub-picometer displacement measurement using a high quality-factor (Q) whispering gallery mode (WGM) borosilicate glass microspherical resonators. Calibrating the expansion of the WGM resonator using a laser Doppler vibrometer (LDV) upon absorption of thermal radiation, 3.7 pm of dimensional change can be experimentally resolved using a 1 mm diameter and $8.4\ \mu \mathrm{m}$ thick glass microspherical shell resonator. COMSOL models presented show that an unprecedented displacement resolution of 89 fm is possible for a microspherical shell resonator with a diameter of 2 mm and a thickness of $2\ \mu \mathrm{m}$.

The yangge~,movement of the 1940s is one of the more wellknown Communist initiatives in the Chinese performing arts. In part, this is because it was one of the earliest Communist efforts to use the performing arts in the service of revolutionary goals and because it was particularly widespread in the border regions of the north. In addition, the yangge movement represented a concerted effort to fuse elements of cosmopolitan political drama with indigenous folk drama New yangge therefore has a position of some importance in discussions of "national form" (minzu xingshi ~~~1\), an oft-discussed issue in the arts in China. The new yangge created in the 1940s were highly varied and, while one goal was the creation of a new form, no definitive final form can be identified for the situation remained fluid and diverse up to the time the movement subsided in the early 1950s. A few features common to new yangge can be identified, however. All the new yangge were adaptations of some form of older yangge, these ranging from street dances with short dramatic episodes (as common in northern Shaanxi) to a type of local opera (as in ningxian). The new yangge differ most ~learly from the old in incorporating new political messages in favour of social changes taking place in the border regions. One particular development of yangge focussed on, the dance, making it a part of popular street celebrations of Liberation, at which time it was very widespread. The more dramatic types of yangge were altered in the direction of spoken drama with an increase in dialogue, a unifying plot in place of a series of episodes, and some elements of realism. Some of the new yangge, and especially the shorter and locally-created ones such as "A Worthy Sister-in-law" (Xiaogu: xi,a,n .JJ, ~~ l ),remained comparatively 'close to old yangge in form. Some


ABSTRACT The language question is topical in Africa because of colonial hegemonies by colonial and languages of global communication such as English, French, and Portuguese. English hegemony in dominant domains fosters the coloniality of language in liberated territories such as Zimbabwe. Part of the decolonising agenda in Africa was to rename the public space so that it reflected the character and heritage of the liberated Africans. This paper establishes the coloniality of culture as expressed through language and heritage displayed in toponyms. The research argues that the renaming process in Zimbabwe did not produce equality or African bias on names used to name and re-name towns, suburbs, and airports. While some elements of the Zimbabwean linguistic landscape were renamed as a decolonising process most of the new names still bear colonial forms as colonialism affected even African identities that are used in the renaming. Renaming in Zimbabwe was biased towards correcting names than changing them, and this process has concentrated on Shona names at the exclusion of other languages and cultures. Conclusions from the paper are important for policymakers as they seek to decolonise names through re-naming. The nexus between toponyms and identity opens up opportunities for further research.


Wood or biomass is the major source of energy for domestic uses on Tanzania mainland especially for cooking meals. This survey about charcoal production and utilization has shown that majority of households are dependent on woodenergy more than other sources of energy. Observations within the City of Dar es Salaam and adjacent areas including some rural areas particularly between Kibaha and Chalinze as well as some other areas in the Coast and Morogoro Regions have shown that sources of woodenergy supply are increasingly becoming critical. Degradation of Miombo Woodlands within the 2 km distance on either side along the Dar es Salaam-Morogoro; Chalinze-Segera and Tanga-Arusha roads suggests that woodenergy shortages are obviously becoming serious and could result in energy for cooking both in the rural and urban areas being more problematic than the case may be for food supply. This is most likely to happen due to inadequate strategies and capacity to produce and utilize woodenergy on a sustainable basis. Where woodenergy shortage becomes obvious, the tendency is for the prices to shoot-up as a result of long distances that are involved to ferry charcoal to consumers. The survey conducted along the Segera-Chalinze stretch showed that charcoal brought to Dar es Salaam involves transportation distance of more than 250 km. This definitely increases the price of charcoal to consumers. Despite this situation charcoal is still a dependable source of energy for cooking because majority of urban dwellers consider it easier to use than firewood and also charcoal is considered to be easily available, easy to store, and still affordable (purchased in small quantities). Random surveys in the Cities of Dar es Salaam and Tanga as well as the Municipality of Morogoro, indicated that many households are still using traditional charcoal cooking stove. Furthermore, production of charcoal in the rural areas is mainly done through the earth kilns. Thus, use of woodenergy for cooking purposes is shown to be very inefficient in terms of methods of production (in the field) and utilization (at the household level and within the informal sector). Efforts initiated since the 1990s to improve earth kilns' efficiency and also to produce and distribute improved charcoal cooking stoves through the private sector, have not produced intended impact. On the other hand, many households are not using electricity as their main source of energy to cook food. Electricity is mainly used for lighting, refrigeration and Television services. A slight increase in electricity tariffs definitely adds a burden to users and at the same time causing more pressure on forests and woodlands due to increased demand for charcoal, which in turn leads to increased environmental degradation. Two decades ago charcoal production was considered to be sustainable in terms of production and forest/woodland resources management. The situation has changed rapidly because amount of charcoal being used in urban areas increased drastically for the last decade. A survey conducted between Mikese and Chalinze along the Dare-esSalaam Morogoro highway, on five roadside charcoal collection sites, counted a total of 505 bags of charcoal. Another survey conducted on a 30 km stretch between Chuma cha pua of and Kitumbi villages, along the ChalinzeSegera highway. Charcoal bags on 22 collection sites were counted and 1214 bags were record. The owners informed that they were awaiting transportation to take the charcoal to Dar es Salaam. Records from the Forestry and Beekeeping Division (FBD) in the Ministry of Natural Resources and Tourism (MNRT) show that on average the City of Dar-es-salaam is using more than 60% of charcoal produced on the mainland or more than 7000 bags of charcoal day In this paper options to produce and supply wood-energy on a sustainable basis are suggested. These include encouraging people to invest in energy production plantations. The Ruvu woodenergy production initiative has demonstrated that as long as local communities are committed and through good planning, it can be done. Furthermore, the importance of alternative sources of domestic energy cannot be overemphasized. The urgent need to reduce pressure on the forests and woodlands through introduction of affordable alternative sources such as electricity, LPG, natural gas and new and renewable energies for cooking purposes is equally important. This can be achieved if Tanzania mainland would adopt policies that encourage and promote wide-use of alternative sources for domestic energy purposes. The government subsidies e.g. on electricity tariffs can promote increased conservation of forests and woodlands on the mainland through reduced demand for woodfuels..


The study examined the effect of work-family conflict on job and family satisfaction among university junior staff in Ghana. It further tested the moderating role of gender on the relationship between work-family conflict dimensions and job and family satisfaction. A quantitative approach was adopted. A multi-stage sampling technique was employed to select 339 respondents. Descriptive and inferential statistics were used to analyse the data. The results revealed a negative effect of work-family conflict on both job satisfaction and family satisfaction. Further analysis showed that gender moderates the relationship between work-family conflict (FIW) and family satisfaction. Recommendations are made to the University authorities and employees on how to minimize the negative effects of work-family which can lead to better job and family satisfaction in this paper.Keywords: work-family conflict, job satisfaction, family satisfaction, gender, junior staff

The surgical management of an appendicular lump still remains a big controversy among surgeons. Conventional treatment according to Ochsner-Sherren regime, has been practiced over years as standard treatment for the Appendicular lump. Failure of conservative regime occurs in 2-4% cases (upto 10% cases), where urgent exploration is essential. Moreover, in 10-20% of the cases, conservative management fails, and the patients need an emergency operation due to deterioration of clinical status within first 48 hour, which is comparatively more difficult and has significant morbidity.

Abstract The chemical composition and the lipoxygenase activity of the leaves essential oil of Rothmannia macrophylla were determined via hydrodistillation. The essential oil was analysed by using gas chromatography and gas chromatography-mass spectrometry (GC/MS) techniques. A total of 20 chemical components (98.3 %) were identified in the oil, which was dominated by oxygenated sesquiterpenes (73.1 %). The major components were τ-muurolol (38.4 %), β-eudesmol (20.9 %), α-cadinol (5.8 %), and δ-cadinene (5.7 %). The essential oil displayed moderate activity towards lipoxygenase activity with IC50 value of 50.5 μg/mL. To the best of the authors' knowledge, this is the initial study that had looked into the essential oil composition of R. macrophylla collected from Malaysia.


Based on the analysis of the formation of pelvis, movement theories and motions of pelvis, the writer thinks that the sprinter's strength of pressing backwards comes from hip joints, and will be influenced directly by the muscles of buttocks. Moving hip will be important in the training; what's more, the function of active pressing of hip joints landing to one side should be paid more attention.


The germination rate,germination energy,germination index,respiratory rate and soluble protein content,root activity of rape seed were determined with the different concentration of Lanthanum(5,10,20,30,50,100 mg/L).The results indicated that low concentration of La(10 mg/L to 30 mg/L) could promote RaPe seed germate and increase seed metabolism and root activity of seedling.The best effect was the concen-tration of 30 mg/L La.The germination and the metabolism of rape seed and root activity of seedling were decreasing with high concentration of La( 30 mg/L).


This research aims to draw attention to what is happening with the hacktivate group, Anonymous. The objective is to understand the phenomenon of social movements on the Internet through the case of Anonymous in Colombia, its motivations, interests, institutions perceptions to this form of activism, and the scope and implications of demonstrations made on Facebook. Under the methodology of virtual ethnography and interviews, it was found that Anonymous activism has taken important steps, to be a valid and efficient form of social protest, using primarly the Facebook social network, as a difussion medium of its cause. Although, achievements have been significant, participation is still shy, discontinuous and dependent on factors such as traditional support mechanisms, such as demonstrations, or dissemination in mass media. Likewise, activists need triggers that lead them to participate and act, in other words, are attentive to the agenda and react to it. The institutions, on the other hand, respond in a reactive way, not proactive, using silent as an answer. There are few organizations, that have a proper management of the issue and choose dialogue as a strategy.

Abstract
Every year, over 1.3 million people die in the traffic. It is estimated that over 90%
of these accidents are caused by human errors. Semi-automated cars looks to be the
solution to lower these deaths.

The goal of this master thesis work has been to look at how to make an autonomous
car more attractive, specifically what would be required for a driver to conduct work
in these upcoming cars. It is theorised that, if work could be safely conducted in
a semi-autonomous vehicle, the increased price tag would be justified by the added
value of using time for work that was previously wasted. This study tested two different
ways of conducting work in the car with a passive task serving as a base line.
A simulation was conducted with 15 participants to try out the three different car
setups. The different setups were, a heads-up display for working tasks, a cell phone
for working tasks, and a relaxation task as a base line. During each task a take-over
request was presented and the response time for the take-over was gathered.

After the results had been analysed it was discovered that the heads-up display
showed the best result with a statistical significance compared to the cell phone
task. It is theorised that the main reasoning for these results were that the system
shutdown the display when the take-over request started, as well as the incentives
gaze towards the road centre. This result suggests that it is not only possible
to conduct work in a car, but if done right, it might even improve the cognitive
recall time which could improve the re-take control of the car. Therefore, it is
recommended to conduct further research within the area of using the car system
to conduct work in autonomous vehicles.

Although earlier North American records of Stictyosiphon soriferus (Reinke) Rosenvinge cannot he substantiated, the species is shown to be common in Newfoundland and is also reported from Nova Scotia. Plants are summer annuals and a component of ephemeral subtidal communities characteristic of suitable inlets and harbors. Only plurilocular reproductive organs are produced. In culture the life history of populations from both sides of the North Atlantic consists of a direct replication by asexual zoospores. A microscopic stage might occur in the field, and is presently known only from European cultures. In eastern Canada S. soriferus is readily distinguishable from S. tortilis (Rupr.) Reinke, S. subsimplex Holden and S. griffithsianus (Le Jol.) Holmes & Batters.


Ambulance services have always been intended for those with life threatening or serious medical illness or injury.1 But over time they have been increasingly used for non-urgent and even social reasons. In natural disasters or emergencies, capacity can be so constrained as to contribute to adverse outcomes and preventable deaths. This happened in November 2016 in Melbourne, Victoria, when an …

This article explores the advancements and potential of LED (Light Emitting Diode) based lighting, adaptive front lighting (AFL), laser lighting, and organic light¬emitting diode (OLED) technologies in automotive applications. AFL systems, using matrix LEDs and advanced sensors and control mechanisms, dynamically adjust the headlight beam pattern to optimize visibility and safety in various driving conditions. The development of the LED package allows an easier and efficient integration in new lighting systems. The benefits of AFL systems based on Digital Micromirror Devices or LED matrix not only improve illumination range while reducing glare, but also enhance communications and awareness of the vehicle on the road. Laser lighting offers high-intensity illumination, longer reach, and is able to provide higher energy efficiency when high luminance is needed. OLED technology, with its thin, flexible, uniform, and segmented light sources, represents an exciting opportunity for automotive lighting design and dynamic communications. In this work we will summarize the current status of innovations in automotive lighting underlying their strengths, weaknesses, future prospects, and opportunities.


Chinese regulators pay very close attention to the systemic risk of the financial sector after entering into the tough development phase of "the New Normal". During the period of stock market "abnormal fluctuation" last year, systemic risk even became an overarching problem for Chinese central government. To monitor the systemic risk in Chinese market, we construct quite a few measures at the macro and micro levels. On the macro level, we find that, both CATFIN (tail risk measure) and DCI (comovement index) have strong predictive power for future economic downside in China, the former one effectively forecast the macroeconomic downside (indexed by Macro-economic Climate Index, MCI) from one month up to twelve months, and the latter one plays a complementary role in predicting MCI from twelve months to twenty months. On the micro level, we employ several widely used measures in a unified framework to measure the systemic contribution of individual firms and identify the first two groups of systemically important institutions, moreover, we show that it is reasonable for Chinese regulators to bring the top 20 firms which are ranked by the relative systemic measures into the Systemic risk regulatory system because there is a big gap between the top 20 firms and the 21th one.

The experiment was conducted in Farmers Training Center (FTC) at Chelia district, West Shewa Zone, Ethiopia especially on cropping season of 2018, for evaluating four faba bean cultivars (Walki, Hachalu, Asebeka and Local) and the efficacy of the fungicide, Trust –Cyomp 439.5 WP at the rate of 1.5 kg/ha at four various spray intervals (once in a week, after two weeks, after three weeks and unsprayed-control) based on conditions on the field for maintaining and managing faba bean chocolate spot disease and its impact on both yield and its relevant components. Entirely sixteen treatments are involved in factorial allignment in Randomized Complete Block Design (RCBD) with three replications. The chocolate spot disease incidence, criticality and region under disease progress curve were the highest in cultivar Local followed by Ashebeka, Hachalu and Walki in unsprayed plots. Among different spray intervals, weekly applied plots were found the most effective in disease reduction with maximum reduction in Walki and minimum in Local cultivar. The effectiveness of cultivars along with spray intervals of fungicide displayed significant variations in pods per plant, yield of the grain, and hundred seed weight; and had no significant effects on seeds per pod. The relative yield loss of 37.31, 35.0 29.0 and 28.5% were recorded from Local, Ashebeka, Walki and Hachalu in unsprayed plots, respectively. Economic analysis showed that the highest net benefits were obtained from Hachalu and Walki (46400 and 44480 birr/ ha) when sprayed at every two weeks intervals and from Ashebeka and Local, the highest benefit (41760 and 36640 birr /ha) was obtained on every one week sprayed interval plots and the least was obtained from Local unsprayed plots (28160birr /ha). The Highest rate of margin based on return was achieved when it was sprayed at every two weeks intervals by Ashebeka (374.3%) followed by Hachalu sprayed at every three weeks spray intervals (227%), but the lowest was obtained from local with spray of fungicide at every three weeks intervals (Birr 42%). The results of this study provide evidences that the reactive nature of faba bean cultivars to weekly and two weeks spray intervals of fungicide applications found to be effective in reducing chocolate spot severity and increased seed yield of faba bean cultivars under field conditions in Chelia district, Ethiopia.

Background. Pediatricians need to competently care for children with hereditary gastrointestinal cancer-predisposing syndromes. Pediatrics resident education on this subject has hithertofore never been studied. Methods. Forty-five US pediatrics/internal medicine-pediatrics program directors allowed their residents to participate in an anonymous questionnaire. The survey-questionnaire was administered as a hyperlinked interactive Web page through e-mail to all consenting residents. Results. Thirty-eight sites including 290 of 1327 residents (21.5%) and 33 internal medicine-pediatrics participated in the study. Knowledge on polyposis syndromes varied by syndrome (14% to 84% correct) but not by year of training. Internal medicine-pediatrics residents were more likely to inquire on family history including polyposis, early colorectal cancer, than pediatrics residents. Conclusions. This study suggests that familiarity with cancer syndromes does not accrue during resident training in pediatrics. The observations suggest that greater emphasis on resident education on these syndromes may improve outcomes in this vulnerable group.


In this paper, a new kind of wet-laid nonwoven material composed of highly fibrillated PPTA (para-phenylene terephthalamide) pulp is used in the preparation of a lithium-ion battery separator. Because the PPTA pulp is composed of fibrils and micro-fibrils, which are mostly less than 1 µm in diameter, the pore size of the separator could be well controlled to less than 1 µm. The effects of PPTA pulp on the pore structure of the separator, thermo-stability, electrochemical property and mechanical properties are researched. The results show that with the increase of PPTA pulp dosage, the pore size of separator is decreased. In addition, this type of separator shows excellent thermal stability. The strength retention of the nonwoven separator is 45% after it is stored at 180°C for 10 minutes, but the polyolefin membrane is completely molten under the same conditions.


An array of 7492 SINIS Josephson junctions was used to generate fast reversed dc (FRDC) voltages of approx. 1.1 V for the study of thermoelectric effects in planar multijunction thermal converters (PMJTC). A bias current source for fast reversing with a frequency of up to 10 kHz has been designed. First measurements with a PMJTC have shown a slope in the FRDC-DC voltage transfer difference versus reversing frequency of about 10/sup -8//Hz. Regression to zero frequency allows to the FRDC-DC transfer difference to be determined with an uncertainty of less than 0.1 /spl mu/V/V.

Nowadays, the usage of web courses for learning activities is very popular among students. Through online learning, students don't have to go to school to learn. Especially during the COVID-19 pandemic, online learning activities have increased significantly. Therefore, this study aims to determine the factors that influence students to use web courses as learning tools and the effectiveness of online learning. An online questionnaire is used to gather data from respondents of different ages and education levels. Structural equation modeling (SEM) was performed to assess the study hypotheses. The results show that academic achievement (AA) is influenced by web course information adoption (IA) as a learning tool. Information adoption (IA) is influenced by information usefulness (IU). Source credibility (SC) and information quality (IQ) both influence information usefulness (IU), while information language (IL) does not. Information quality (IQ) is influenced by intrinsic, contextual, and accessibility information quality. This study adds to the literature by empirically testing and theorizing the effects of free websites as a learning tool on the academic achievement of Indonesian students who are studying in bilingual surroundings. This research shows that Indonesian High School and University student feel helped with the development and use of free online learning websites or software that is available in Indonesia so they are able to use it to develop their soft skills, even help them reach academic goals.


This article examines how cultural beliefs and patriarchal practices during the early period of the spread of Christianity promoted intimate partner violence (IPV) against women in the church. The article begins by exploring some cultural and patriarchal beliefs that were practised by the Jews and Giriama people during the pre-evangelistic period that promoted IPV against women through religious and cultural practices to see violence as normal, thus choosing to persevere in violent relationships. New strategies for preventing IPV against women have been discussed. In this descriptive research, data were collected from 52 informants using questionnaires and in-depth interviews. The study interviewed 30 women facing IPV individually. Abused women provided information in focus group discussions. Ten pastors were sampled in order to gather data on how cultural and patriarchal practices with the support of biased biblical interpretation of texts, promoted IPV against Christian women. Twelve questionnaires were administered to six gender officers, three probation officers and three social workers, and the findings were used to supplement data collected from the key informants. This study established that some Bible texts are interpreted and used by wife abusers and pastors offering counselling to the IPV victims to promote and justify IPV. It, therefore, recommended that the church should organise to re-read and re-learn these Bible texts with a view to interpreting them without being biased against women. The church should also re-examine all patriarchal passages in the Bible with a view to facilitating contextual and reasoned scrutiny of the male-controlled beliefs and practices that promote IPV against women. The article established that cultural beliefs and patriarchal practices promote IPV against women. Some pastors and wife abusers interpret some Bible verses to justify spousal abuse; however, if the problem of IPV is to be prevented, the church, the government, and other stakeholders involved in a war against IPV on women must embrace new strategies that are free from cultural and patriarchal beliefs and practices.


This article analyzes the typical Langevin problem, i.e. the dynamics of a charged particle under the circularly successive influence of several simple impulse functions moving in a double-well potential and a time-dependent magnetic field. Using the stroboscopic sampling, by selecting an appropriate magnetic intensity and time interval, we reduce the Langevin equation to a class complex mapping system. Through an experimental mathematical method, the authors study the structures of generalized M–J (Mandelbrot–Julia) sets generated by the complex mapping system, and expatiate the theory of Brownian movement. The authors find that:. (1) This paper extends Shirriff constructed M sets by combining two simple complex mappings;. (2) The fractal structure of the generalized M–J sets may visually depict the rule of Brownian movement, and the infinite overlapping embedment self-similar structure reflects the complexity of Brownian movement;. (3) Whether the selected time interval is significant or not determines the continuity of the fractal structure for the generalized M–J sets;. (4) The changing rule of particle velocity depends on the different choices of the principal range of phase angle;. (5) If we change the choices of the magnetic intensity and time interval, for example, we choose a randomly fluctuating magnetic field, the generalized J sets may emerge the interior-filling structure feature, i.e. "explosion" phenomena appear in the closure of the unstable periodic orbits of the particle in the velocity space.


IV.-MYOCARDITIS, OR NEURO-MUSCULAR CARDIAC AFFECTIONS. THis section undoubtedly contains the miiost difficult clinical cases of rlleumatic heart disease, for the structure of the nmyocardium is more conmplex than that of the pericardium or endocardium, and the physical signs that point to its injury are more difficult to appreciate. A brief allusion to the patlhological chlanges will be lhelpful in illustrating these points. In general terms we lhave to consider the mtuscular tissue of tlle hleart wall and the fibrots framework in wlicih it is set-wlhiclh contains blood vessels, lymplhatics and nerves. An objection to the termi " myocarditis ' is that rlheumiiatism may damnage the muscle fibres witlhout producing any degree of inflammation, for experiment sliows tljat a virulent infection mav produce fatty clhange in tlle nmuscular fibres, and yet no ,evidence of inflammatory cllanges be fortlhcoming in the connective tissue framework. On the othier hand, tllere is no doubt that myocarditis may also occur


In contrast to the previous two chapters, which theologically engage rhythm in continental philosophy, this chapter examines Augustine's explicitly theological approach to rhythm and its various receptions. The chapter uses Przywara's scheme of intra-creaturely and theological analogies to frame Augustine's treatment of rhythm in chapter six of De Musica. While Agamben represents an intra-creaturely perspective, Augustine represents a theological perspective. The degree to which this synchronic, theological view, which envisions rhythm as that which binds metaphysical layers of reality together allowing for communication between them, is problematic depends on the degree to which it is uncoupled from an intra-creaturely perspective like that of Agamben. Proponents of Radical Orthodoxy who propose an Augustinian musical ontology represent such an uncoupling, leading to a total order that betrays creatureliness. Erich Przywara's interpretation, in contrast, retains the tension in Augustine between both the theological perspective on reality as harmonious and the intra-creaturely experience of interruption.


Iceland has suffered from severe soil erosion since settlement with losses up to 60% of pre-settlement vegetation. Large land remediation projects are underway using Betula pubescens. A huge potential for carbon sequestration exists by this revegetation of degraded areas. Little is known about soil development when using native forest vegetation for land restoration. This study aims to both estimate the carbon storage and sequestration rate in these systems and establish constrains on the pedogenetic factors and their influence on soil development. A chronosequence of afforested areas, both natural succession from sown plots and planted areas, reaching 60 years back has been established and compared to natural old-growth forests in the same area. 3 subplots were identified for each age group and soil sampled along transects in each plot. Soil profiles were described, sampled and water content sensors installed at representative sites. Profiles showed stronger horizonation with age with a slight lowering of soil pH in the topsoil.


Candidate mnterials were screened as to their efficiency for removing boranes from contaminated air streams. Chemical tests and animal exposure studies were done. The results show that the following give temporary protection against: diborane --chemical cartridge respirator charged with Hopcalite; pentaborane --chemical cartridge respirator charged with activated C; pentaborane and decaborane --filler medium of silica gel and activated C; and diborane, pentaborane, and decaborane -- silica gel, active Hopealite, and activated C.

Chromium mediated synthesis of 4-iodo-1-triisopropylsilylindole followed by 4-methoxycarbonyl-methylthiation by palladium catalysed cross coupling with methoxycarbonylmethylthio(trialkyl)-stannane and aldol condensation gave the key α-thioacrylate intermediate 5. The Z-geometry of the major isomer of 5 was determined by X-ray crystal analysis. Closure of ring C by a novel fluoride ion catalysed formation of the 2a–3 bond completed a short synthesis of (±)-chuangxinmycin methyl ester 1(R = Me).


Breast cancer is the most common cancer among women and majority of diagnosed cancers are estrogen receptor (ER)-positive. Estrogen facilitates its effects by binding to its receptors, estrogen receptor (ER)-α and ER-β. In a search to identify novel ERα inhibitors, a multivariate regression analysis was carried out on a set of 80 compounds known to inhibit ERα in vitro belonging to benzofurans, diphenyl amine analogs, sulfoximine-based acyclic triaryl olefins, isoxazole, thiazolidinone derivatives, tamoxifen mimics, pyrazolo(1,5a)pyrimidines and chromen-2-one derivatives, respectively, and all molecules are known to inhibit the estrogen receptor in MCF-7 cancer cell lines. Nearly three new QSAR models were built by dividing the complete data set into 63 molecule training set and a 6 molecule validation set, after excluding outlying data based on Relative Error and Standardized Residuals. Predictive ability of new models (7, 4 and 6 variables) were evaluated and observed that all statistical values are within limits. R 2 cvext was found to be 0.99 for all the three model equations. Therefore, to define the statistical quality of activity prediction, FIT Kubinyi function was used, where the 7-variable model was chosen as best model as it possessed high FIT value than others. This model displayed good internal predictivity with q 2 value of 0.99 and was able to explain 91 % variance of inhibitory activities. The model was further validated by applying the y-randomization test and the low R 2 and Q 2 values indicated that the results obtained in the QSAR model are not due to chance correlation. The model indicated an increase in HOMO, H-bond acceptors, donors and LogP with reduction in LUMO and lipophilic character would enhance ERα inhibition.

CPAP is considered the gold standard treatment in OSA and is highly efficacious in controlling OSA symptoms. However, treatment effectiveness is limited because of many factors including low adherence due to side effects. This review highlights the range of side effects associated with CPAP therapy in patients with OSA. This information is important for the initiation of patients onto CPAP as well as their continued care while on treatment, given the increase in non‐medically supervised CPAP care models in use globally.


Coherent optical systems for short-reach links have seen a boost in their popularity with the standardization of 400ZR. These systems need to be cost and power-efficient, while coping with the ever increase in traffic demand. The use of probabilistic constellation shaping (PCS) can help meet these demands, since it reduces the gap to the channel capacity. However, studies concerning PCS typically include optical amplification; therefore, its gain in amplifier-less systems has been somewhat uncertain. In this work, we focus on an amplifier-less coherent optical link employing PCS, reducing both power consumption and system complexity due to the removal of the amplifier. We employ PCS for different modulation orders and bit rates, while optimizing several key parameters such as the FEC coding overhead, modulation depth and clipping. With this comprehensive study, we demonstrate by system simulation and experimental validation that PCS is beneficial even for amplifier-less systems, since it introduces residual gains while allowing higher flexibility in defining the net bit rate in a system with fixed baud rate.


Many applications process data in which there exists a ``conservation law'' between related quantities. For example, in traffic monitoring, every incoming event, such as a packet's entering a router or a car's entering an intersection, should ideally have an immediate outgoing counterpart. We propose a new class of constraints -- Conservation Rules -- that express the semantics and characterize the data quality of such applications. We give confidence metrics that quantify how strongly a conservation rule holds and present approximation algorithms (with error guarantees) for the problem of discovering a concise summary of subsets of the data that satisfy a given conservation rule. Using real data, we demonstrate the utility of conservation rules and we show order-of-magnitude performance improvements of our discovery algorithms over naive approaches.


With the popularity of ready-mixed concrete,the gradual loss in slump of the ready-mixed concrete often causes a lot of problems such as the ready-mixed concrete is hard to unloading from concrete mix vehicle,pumping and dense molding.The experiments which research the effect of fly ash amount on the gradual loss in slump and flow of the ready-mixed fly ash concrete with and without water reducing agent are carried out.According to the different transfer distances,the fly ash optimum amounts for concrete mixtures under different durations are given,which is benefit for engineering.


800x600 Results of national assessment of theoretical and technical energy potentials of forest biomass in Ukraine that were obtained in a framework of Biomass Energy Europe project (BEE) are presented. It has been found that almost 35% of all the forest biomass possible for energy use is located in the Polissya zone, up to 30% – in the Carpathians and in the Forest-Steppe zone, only about 5% – in Steppe zone. Forests of the Carpathians are characterized by highest density of energy biomass – 457,2 kJ·(m 2 ) -1 , in other forest growing zones this index is considerably lower: Polissya – 255,8 kJ·(m 2 ) -1 , Forest-Steppe – 144,2 kJ·(m 2 ) -1 , Steppe – 36,5 kJ·(m 2 ) -1 . Validation of applicability of the Harmonized European methodology for assessment of potentials of forest biomass by carrying out a parallel assessment with use of an alternative stand-wise method is performed.

Growing evidence points to considerable mental health impacts of the prolonged COVID-19 pandemic, though data from longitudinal studies in rheumatic diseases are sparse.We explored distinct trajectories ofdepressive symptoms in the year prior to and throughout the first 2-years of the COVID-19 pandemic inadults with RA.CATCH is a prospective multi-center study of adults with early RA (symptoms <1 year; 81% met 2010 ACR/EULAR criteria at enrolment) who receive care from rheumatologists across Canada. Prior to the pandemic, participants completed PROs and rheumatologists conducted RA assessments during scheduled in-person study visits. After March 2020, ongoing collection of PROs continued at in-person and remote visits.We used group-based trajectory modeling to identify latent groups with at least mild depression (PROMIS 4a depression score ≥55) in participants with ≥1 visits in the year prior to the pandemic (3/19-2/20) and ≥1 visits during pandemic (3/20-1/22) and identified prepandemic individual and clinical characteristics and PROs associated with each trajectory.The analytic sample included 989 participants with a mean (SD) age of 60 (14) and disease duration of 6 (4) years. 73% were women, 84% white, 60% had completed some post-secondary education, and 77% were in CDAI REM/LDA at visit closest to the start of pandemic.The best model included 4 groups (posterior probabilities ≥0.80 for each group): 1)Resilient(none-minimal depression throughout: N=594; 60%);Worsening(none/minimal to mild: N=222;22%);Improving(mild-resilient: N=80;8%); andPersistent(moderate-severe throughout: N=93;9%)(Figure 1).As compared with the Resilient group, those with Worsening Depression were more likely to be female, have a higher prepandemic CDAI, MD and patient global, and report worse pain, disability, anxiety, depression, fatigue, sleep disturbance, and lower participation (Table 1).Figure 1.Table 1.Mean(SD); N(%)Worsening N=222 (22%)Resilient N=594 (60%)Improving N=80 (8%)Persistent N=93 (9%)SIGAge60 (15)61 (13)59 (13)61 (13)0.538Female173 (78%)406 (68%)57 (71%)74 (80%)0.016White194 (87%)533 (90%)67 (84%)71 (76%)0.004Education > high school143 (64%)388(65%)56 (70%)42 (45%)0.001RDCI (excl depression)1.2 (1.2)1.0 (1.2)1.0 (1.1)1.0 (1.1)0.174CDAI6.7 (8.2)5.4 (8.5)11.3 (13.9)13.0 (13.1)<0.001csDMARDs ±MTX198 (89%)547 (92%)73 (91%)67 (94%)0.513MTX only153 (69%)436 (73%)62 (78%)67 (72%)0.443Biologic or JAK43 (19%)102 (17%)12 (15%)26 (28%)0.073Corticosteroids36 (16%)86 (14%)26 (33%)20 (22%)0.001Patient Global3.1 (2.4)1.2 (2.1)3.9 (2.9)5.3 (2.7)<0.001PROMIS Anxiety >5597 (44%)44 (7%)58 (73%)86 (92%)<0.001PROMIS Depression >5583 (37%)13 (2%)70 (88%)90 (97%)<0.001PROMIS Fatigue >5583 (37%)94 (16%)42 (53%)74 (80%)<0.001PROMIS Pain >55125 (56%)187 (31%)55 (69%)76 (82%)<0.001PROMIS Physical Function <45132 (59%)238 (40%)51 (64%)78 (84%)<0.001PROMIS Participation <45107 (48%)141 (24%)49 (61%)72 (77%)<0.001PROMIS Sleep Problems >5562 (28%)88 (15%)33 (41%)so (54%)<0.001Although 60% of Canadian RA patients had consistently good mental health during the first 2 years of the COVID-19 pandemic, more than 1 in 5 reported deteriorating mood suggesting a cumulative impact over time; 9% had persistent depression and 8% improving mood. The proportion of adults with RA with at least mild symptoms of depression may be more than twice that reported for the general Canadian population. Participants with worsening depressive symptoms during the pandemic were more likely to be female, have higher prepandemic disease activity, symptoms, disability, and higher impairments in participation. Given the impact of depression on quality of life, inflammation, and disease management, vulnerable groups may benefit from more frequent evaluation and additional support from rheumatology providers.CATCH was designed and implemented by the investigators and financially supported through unrestricted research grants from: Amgen and Pfizer Canada since 2007; AbbVie Canada since 2011; Medexus since 2013; Sandoz Canada since 2019; Fresenius Kabi Canada since 2021; Organon Canada since 2021.Previous funding from Hoffman La Roche (2011-21); Sanofi Genzyme (2016-7); Eli Lilly Canada (2016-20); Merck Canada (2017-21) and; Gilead Sciences Canada (2020-21).Susan J.

Experiments and simulations indicate the persistent presence of ballooning filamentary structures well into the nonlinear stage of edge localized modes (ELMs). Recent analytic theory developed for the nonlinear ballooning instability suggests that the solutions of the associated local linear ballooning mode equations continue to be valid solutions of the equations governing the intermediate nonlinear regime [1]. This implies that a perturbation that evolves from a linear ballooning instability will continue to grow exponentially at the same growth rate, and maintain its filament mode structure of the corresponding linear phase in the intermediate nonlinear stage. This may explain why in experiments and in simulations, particularly in the precursor and pre-collapse phases, the ELM filament, which is a nonlinear structure, strongly resembles the structure of a linear ballooning filament. The persistence of linear growth is consistent with previous findings for the nonlinear line-tied g-mode in slab geometry [2]. Comparison between the analytic theory and direct ideal MHD simulations will be discussed [3]. [1] P. Zhu and C. C. Hegna, Phys. Plasmas 15, 092306 (2008). [2] P. Zhu, C. C. Hegna, C. R. Sovinec, A.

We study a coupled Zakharov-Kuznetsov system, which is an
extension of a coupled Korteweg-de Vries system in the sense of the Zakharov-Kuznetsov equation. Firstly, we obtain some exact solutions of the coupled
Zakharov-Kuznetsov system using the simplest equation method. Secondly,
the conservation laws for the coupled Zakharov-Kuznetsov system will be
constructed by using the multiplier approach.


Today, the basic radio communication standards for building self-organizing networks such as MANET, VANET and FANET are IEEE 802.11s and IEEE 802.11p. The link layer is responsible for establishing and conducting a communication session in these networks. It includes a variety of procedures, the main of which are synchronization procedures, random multiple media access, reserved media access and transmitter power control of network elements. Moreover, in digital radio communication networks of the IEEE 802.11 standards family, both centralized synchronization and distributed synchronization of such network elements are used. However, in digital radio networks of the IEEE 802.11s and IEEE 802.11p standards, the key procedure for establishing and conducting a communication session is the distributed synchronization of the network data elements. It should be noted that there is no descriptive model of distributed synchronization of the IEEE 802.11s and IEEE 802.11p standards digital radio communication network elements, taking into account these standards features. All elements of the IEEE 802.11s and IEEE 802.11p digital radio network send Beacons on a competitive basis. This occurs cyclically at the start of the repeating sync interval. In this regard, the occurrence of three events is possible: successful transmission of the synchronizing Beacon packet, its collision with a similar packet and a service or user data packet. To prevent (reduce) the number of collisions in a digital radio communication network, it is necessary to maintain a constant time difference between the internal time of all network elements. It is worth noting that maintaining a constant time difference for all digital radio communication network elements through guaranteed and timely sending of synchronizing Beacon packets is the main mechanism for distributed synchronization of such network elements. In the event that the calculated value of the time difference Toffsetni for one of the neighboring elements of the digital radio communication network does not coincide with the analogous value obtained in the past synchronization interval Toffsetni-1, then the correction of the own internal TTSF time of the IEEE 802.11s and IEEE 802.11p standards digital radio communication network element begins. The procedure for adjusting the network element internal time continues until the maximum value of this element internal time offset TMaxClockDrift is equal to zero. Also, to reduce or prevent collisions of synchronizing Beacon packets in the data transmission channel, each network element both initially, when entering the network, and immediately when collisions of synchronizing packets occur, Beacon selects and sets the timing parameters of synchronization so that they do not coincide with similar parameters of neighboring network elements. The developed descriptive model of the IEEE 802.11s and IEEE 802.11p standards digital radio communication network elements distributed synchronization includes algorithms for the such network elements functioning, adjusting the such elements intrinsic internal time, searching for an alternative value for the start time of a repeating synchronization interval and adjusting it. The presented model is applicable in the development of analytical and simulation models for assessing the IEEE 802.11s and IEEE 802.11p standards digital radio communication network performance, taking into account the distributed synchronization of such network elements.


The KBS for optimizing electricity cost was established by researching something about generation cost based on the method of combining mathematic model with knowledge model.The system is used to calculate electricity cost and optimize decision-making.It is very useful to optimize the operation,reduce the cost and boost up the competition power of the enterprise in electricity market.


Understanding of air circulation mechanisms is an important constituent for low pressure environmental control, low pressure atmospheres were suggested for Martian (Planetary) Greenhouse design (Wheeler et al., 2000) to minimize system construction materials and cost. Temperature distribution and moisture exchange (humidity level) are just two important components of environmental control which are affected by air circulation.


[Objective] To assess the clinical effects of distal arterial bypass for the treatment of critical lower limb ischemia.[Methods] We retrospectively analyzed 36 patients with critical lower limb ischemia,for which distal arterial bypass was performed from January,2003 to March,2007.[Results] In 33 cases(91.7%) symptoms were relieved,with resting pain disappeared and skin temperature improved.Ankle brachial index(ABI) increased significantly from 0.12±0.15 to 0.87±0.21 perioperatively(P 0.001).Postoperatively,31 cases were followed up for 1 year to 3 years.The primary graft patency rates in this series were 85%,72% and 70% in 1 year,2 years and 3 years,respectively.The secondary graft patency rates were 87%,73% and 72% in 1 year,2 years and 3 years,respectively.[Conclusion] The distal arterial bypass is one of the effective methods for the treatment of critical lower extremity ischemia and the salvage of the limbs.


The violation of Bell's theorem is a very simple way to see that there is no underlying classical interpretation of quantum mechanics. The measurements made on the photons shows that light signal (information) could travel between them, hence completely eliminating any chance that the result was due to anything other than entanglement. Entanglement has been studied extensively for understanding the mysteries of non-classical correlations between quantum systems. It was found that violation of Bell's inequalities could be trivially calculated and for sets of nonmaximally entangled states of two qubits, comparing these entanglement measures may lead to different entanglement orderings of the states. On the other hand, although it is not an entanglement measure and not monotonic under local operations, due to its ability of detecting multipartite entanglement, quantum Fisher information (QFI) has recently received an intense attraction generally with entanglement in the focus. In this work, we visit violation of Bell's inequalities problem with a different approach. Generating a thousand random quantum states and performing an optimization based on local general rotations of each qubit, we calculate the maximal QFI for each state. We analyze the maximized QFI in comparison with violation in Bell's inequalities and we make similar comparison of this violation with commonly studied entanglement measures, negativity and relative entropy of entanglement. We show that there are interesting orderings for system states.


The purpose of this paper was to examine whether brokers who adopted Net stock trading perceived differently from those of non-net based brokers. The primary data based on 196 brokers (92 brokers and 104 non-net based brokers) were analyzed using advanced multivariate techniques like factor analysis and discriminant analysis besides percentages, means, and Z-test. Results clearly indicated that demographics relative to attitude dimensions were fairly strong in classifying brokers as Net brokers or non-Net brokers. As regards demographics, young brokers were more adaptable to the latest Internet technology as a medium of providing trading facility in comparison to aged and experienced brokers due to lack of education and awareness about this medium. As for as the attitude dimensions were concerned, 'economic, convenience and transparency' contributed significantly in discriminating between Net brokers and non-Net brokers.

We present a new quantum‐mechanical resonance theory based on the first‐order reduced density matrix and its representation in terms of natural bond orbitals (NBOs). This "natural" resonance theory (NRT) departs in important respects from the classical Pauling‐Wheland formulation, yet it leads to quantitative resonance weights that are in qualitative accord with conventional resonance theory and chemical intuition. The NRT variational functional leads to an optimal resonance‐weighted approximation to the full density matrix, combining the "single reference" limit of weak delocalization (incorporating diagonal population changes only) with the full "multireference" limit of strong delocalization (incorporating off‐diagonal couplings between resonance structures. The NRT variational functional yields an error measure that serves as an intrinsic criterion of accuracy of the resonance‐theoretic description. The NRT program structure, algorithms, and numerical characteristics are described in supplementary material, and detailed chemical applications are presented in two companion papers. © 1998 John Wiley & Sons, Inc. J Comput Chem 19: 593–609, 1998


Fe films have been prepared in ultrahigh vacuum by epitaxial growth on MgO(001) substrates. Spin-resolved inverse photoemission measurements indicate that nonannealed overlayers display lower spectroscopic quality than the corresponding bulk system. Low energy electron diffraction and x-ray photoemission reveal that annealing promotes oxygen surface segregation giving rise to a c(2×2) reconstruction even in several hundred A thick films. It is found that high-quality Fe(001) single crystal films with clean and well ordered surfaces can be obtained after high temperature annealing (∼600 °C) of relatively thick films (>1000 A).

With the popularity and advancements of smartphones, mobile users can sense the city using variety of sensors opportunistically, and forward the sensory data to the monitoring center for building sensing maps through intermittent connections with short-range communications. In order to build sensing maps satisfying specific sensing quality with low delay and energy consumption, we design COUPON, a novel cooperative sensing and data forwarding framework. We first notice that cooperative sensing scheme can eliminate sampling redundancy and hence save energy. Then we design two cooperative forwarding schemes by leveraging data fusion: Epidemic Routing with Fusion (ERF) and Binary Spray-and-Wait with Fusion (BSWF). Different from previous work assuming that all packets are propagated individually, we consider that packets are spatial-temporal correlated in the forwarding process, and derive the dissemination law of correlated packets. We theoretically prove that our cooperative forwarding schemes can achieve better tradeoff between delivery delay and transmission overhead. We evaluate our proposed framework and schemes with real mobile traces. Extensive simulations demonstrate that the cooperative sensing scheme can reduce the number of samplings by 93% compared with the non-cooperative scheme, ERF can reduce the transmission overhead by 78% compared with Epidemic Routing (ER), BSWF can increase the delivery ratio by 16%, and reduce the delivery delay and transmission overhead by 5% and 32% respectively, compared with Binary Spray-and-Wait (BSW).


Numerical simulations of turbulent polymer solutions using the FENE-P model are used to characterize the action of polymers on turbulence in drag-reduced flows. The energetics of turbulence is investigated by correlating the work done by polymers on the flow with turbulent structures. Polymers are found to store and to release energy to the flow in a well-organized manner. The storage of energy occurs around near-wall vortices as has been anticipated for a long time. Quite unexpectedly, coherent release of energy is observed in the very near-wall region. Large fluctuations of polymer work are shown to re-energize decaying streamwise velocity fluctuations in high-speed streaks just above the viscous sublayer. These distinct behaviours are used to propose an autonomous regeneration cycle of polymer wall turbulence, in the spirit of Jiménez & Pinelli (1999).


Social security of rural migrant workers is an important social issue,which attracts much attention from central and local governments.Local governments set up different models in dealing with rural migrant workers in their practice.Guangdong Model and Shanghai model are two typical examples,the former one involves rural migrant workers into urban security system and the latter one sets up a new system for rural migrant workers in social security.The paper makes a deep analysis on the two models.


Based on Petri net models,this paper addresses the deadlock avoidance problem in automated manufacturing sys- tems.First,for manufacturing systems without center resources, it is proved that the systems have only two kinds of reachable states—safe and deadlock.An optimal or maximally permissive deadlock avoidance policy with polynomial online-computation complexity is obtained through one-step look-ahead.Then,for a general system,an auxiliary Petri net is introduced.By apply- ing the presented design method of optimal deadlock avoidance policy to the auxiliary net,a suboptimal polynomial-complexity deadlock avoidance policy for the general system is obtained.


Lot-to-Lot data is needed in order to assure a constant and controlled process. In order to determine the stability of molding compound, we did a full characterization using three lots of material. Elastic modulus, and coefficient of thermal expansion (CTE), glass transition temperature, and filler content were determined using molded test specimens. The same level of understanding is also needed in the area of molding compound rheology. The molding compound viscosity at several shear rates was determined. It was found that lot-to-lot viscosity were similar at high shear rates during the early stage of the reaction. The total heat, rate and %conversion of reaction, and activation energy were calculated. Time and temperature dependence of the molding compound were evaluated by monitoring the rate constant versus time plots. There was no significant difference in CTE and %filler whether the material was molded in 240L PQFP packages or test specimens. However, molded packages were observed to have 10% lower in elastic modulus and 5% lower in Tg than molded test specimens. Finally, effect of moisture ingress in uncured pellets competing of the molding compound was investigated. While information the process capability can be maintained, one critical parameter which can effect the assembly process is moisture. Moisture absorbed by the molding compound showed an influence on a spiral flow test, but it does not appear to significantly change the mechanical properties of the molded packages.


Analysis of measurements by the Dynamics Explorer 2 satellite indicates a close connection between atmospheric wave disturbances and wind circulation in the polar thermosphere. According to satellite observations, large-amplitude acoustic-gravity waves are systematically observed in the regions of formation of powerful wind systems. At the same time, the azimuths of AGW propagation are spatially consistent with the directions of wind circulation. Waves propagate mainly against the wind, and their amplitude is approximately proportional to the wind speed. In order to explain the experimental data, the paper theoretically investigated the changes in the amplitudes of AGW in a horizontally inhomogeneous wind flow. The dispersion equation of the AGW in the reference frame of the medium, which moves with a non-uniform speed, was obtained. When obtaining it, inertial forces were taken into account, as well as the change in the background density of the atmosphere in an inhomogeneous flow. It is shown that under the slow change in wind speed, the real part of this equation coincides with the dispersion equation of AGW for a stationary medium. An expression for the change in the amplitude of waves in a moving medium was obtained, according to which, in an oncoming inhomogeneous wind, the amplitude of the wave increases approximately according to a linear law, which is consistent with the data of satellite observations.


Dose mimicking allows for the automatic creation and optimization of coplanar/non-coplanar three dimensional conformal radiation therapy (3DCRT), step-and-shoot intensitymodulated radiation therapy (IMRT), sliding window IMRT, and volumetric modulated arc therapy (VMAT) treatment plans that mimics a reference radiotherapy treatment plan of any modality. The algorithm is currently used in multi-criteria optimization (MCO) to go from a navigated fluence-based plan to a plan that is actually deliverable [1,2]. The algorithm is also used to create alternative treatment plans in various treatment planning systems (TPSs). Provided that the dose mimicking algorithm is capable of creating deliverable treatment plans of high plan quality, it would ensure a high level of flexibility in clinical practice. The dose mimicking algorithm would give clinics (with TPSs which have dose mimicking capabilities) the ability of automated multi-modality optimization, which could be used to verify that a patient is always treated with the optimal treatment technique [3]. It would also supply alternative treatment plans if a treatment technique/machine becomes unavailable, ensuring continuous patient treatment, which is of great importance for therapeutic outcome [4]. Hence, the purpose of this study was to investigate the plan quality achieved for dual-arc VMAT plans, optimized via dose mimicking. A second purpose was to verify that such plans can be accurately delivered at a clinically commissioned linear accelerator (linac).


Between January 15 and March 31 2020, Taiwan reported 31 800 subjects tested, 322 confirmed COVID-19 cases (including 276 imported and 46 indigenous), and five deaths. Taiwan has been able to control the epidemic more effectively than many other countries in the Asia-Pacific region through a combination of measures, including border control; testing and quarantine of individuals with history of contacts; at-home self-isolation; and real-time linking of immigration records with healthcare information. Society maintains trust in governmental agencies thanks to daily press conferences, with full disclosure of key metrics and clear guidelines.1 An average of 675.76 tests per million individuals were performed. Our containment strategy ensured the numbers of new cases per day remain in single digits, delaying peak time and protecting the medical system from being overwhelmed. While first responses by primary health care is slowing down the outbreak, the Taiwan Medical Association (TMA) has devised a long-term strategy to handle the inevitable scenario of community transmission. Our plan relies on a …


Abstract A sensitive and selective H2O2 electrochemical sensor based on graphene–polyacrylamide (G-PAM) composites was developed. Graphene (G) was synthesised via the electrochemical reduction of graphene oxide, and then PAM films were electrosynthesised on G modified glassy carbon electrode to prepare G-PAM. A novel H2O2 sensor was obtained by immobilising horseradish peroxidase (HRP) into the G-PAM via the hydrogen bonding between PAM and HRP. The as prepared H2O2 sensor exhibited high sensitivity, selectivity and reproducibility in the determination of H2O2, which was attributed to the introduction of G to this sensor. Also in this paper, the apparent Michaelis–Menten constant of HRP was calculated.


Urban parks, as one of the starting points of urban green development, are a composite product of the interaction between people and nature. They play an important role in displaying and continuing the city's culture. Therefore, it is critical to attach importance to the design and renewal of urban parks. This article takes Wuhan City Park as the specific research object, and extracts the "water", "fish" and "bubble" in the "river culture" as landscape design elements. To show, let people feel the baptism of urban culture while visiting the park, and re-entrust the park with the mission of inheriting cultural heritage.


Introduction
------------
The physicist Andreevich Artsimovich in the 1970 wrote that "thermonuclear
[fusion] energy will be ready when mankind needs it". Considering the actual
world energy situation and the effect on the environment due to the present
harnessing of the different sources of energy, the hope is that time for fusion
is finally arrived.

Background and Motivation
-------------------------
The activities carried out in the framework of this thesis regarded the devel-
opment, implementation and application of algorithms for classification and
prediction of disruptions in Tokamaks.
The balance of plasmas in a magnetic field can be described by the theory
of magneto-hydro-dynamic (MHD). MHD instabilities are among the most
serious factors that limit fusion devices operation in magnetic confinement
configurations. When they occur on a large scale can degrade the perfor-
mance of the plasma and lead to loss of confinement and control.
A disruption is a sudden loss of stability or confinement of tokamak
plasma; it is a critical event in which the plasma energy is lost within a
time span of few milliseconds exposing the plasma facing components to se-
vere thermo-mechanical stresses and conductors surrounding the vessel to
huge electromagnetic forces. Therefore, it becomes of primary importance
to avoid or mitigate disruptions in order to preserve the integrity of the ma-
chine. This aspect and the understanding of disruptive phenomena play a
key role in design and running of new experimental devices as ITER, cur-
rently under construction in Cadarache (France), which will have the task
of demonstrating the feasibility of fusion energy production from a technical
and engineering point of view.
These considerations motivate a strong interest in developing methods
and techniques aimed to minimize both number and severity of disruptions.
Furthermore when a disruption occurs it would be particularly important to
be able to distinguish among its difierent types in order to improve avoidance
and mitigation strategies. Since physical models able to reliably recognize
and predict the occurrence of disruptions are currently not available, the re-
search carried out fits in the broad framework of machine learning techniques
that have been exploited as an alternative approach to disruption prediction
and automatic classification.
Promising approaches to prediction and classification are represented by
the so-called "data-based" methods: to this purpose, existing systems have
been applied and further developed and new approaches have been investi-
gated.
The mentioned activity has been carried out in collaboration with the
University of Cagliari and European Research Centers for nuclear fusion,
taking as case study some of the most important experimental machines
such as JET and ASDEX Upgrade (AUG), with several months of research
spent at the Culham Science Centre.

Outline of the Thesis
---------------------
In chapter 1 the perspectives of fusion in the world energy context as an
almost unlimited source of energy for the future are discussed, with particu-
lar reference to the role of magnetic confinement. Furthermore, the bases of
fusion reactions have been introduced.
In chapter 2 the main aspects of plasma stability in tokamaks configu-
rations are described with the aim to provide an adequate reference for all
the discussions of the following chapters. In particular, the main parameters
related to plasma stability, which have been used for the construction of the
databases, have been introduced.
The chapter 3 is focused on the description of the operational limits
with reference to the main quantities which should be maximized to im-
prove plasma performance. Everything, also in the previous chapters, has
been framed to introduce the key problems which this thesis has addressed:
analysis, prediction and classification of disruptions. After the main consid-
erations about the operational limits, the main phases, the causes and the
consequences of disruptions have been discussed, trying to integrate the sta-
bility concepts introduced in the previous chapter.
The chapter 4 is finalized to provide an insight of the Machine Learn-
ing methods which represent the starting point of all the analysis and algo-
rithms implemented for disruption prediction and classification. Today the
large amount of data available from fusion experiments and their character
of high-dimensionality make particularly difficult handling, processing, un-
derstanding and extracting properly what is really important among all the
available information. Machine Learning allows to deal with the problem in
efficient way. Therefore, a framework of all the techniques exploited for the
analysis has been provided, with particular reference to the Manifold Learn-
ing algorithms as Self Organizing Maps (SOMs) and Generative Topographic
Mappings (GTMs). Also reference methods such as k-Nearest Neighbor (k-
NN) or more recent methods such as Conformal Predictors, exploited for
validation and reliability assessment purposes, have been described.
In chapter 5 the state of the art of machine learning techniques ap-
plied to disruption prediction and classification is presented, describing in
particular the main applications with the widely employed Neural Networks,
such Multi Layer Perceptrons (MLPs), Support Vector Machines (SVMs)
and Self Organizing Maps (SOMs), and statistical methods such as Discrim-
inant Analysis or Multiple Threshold technique. Strengths and weaknesses
have also been discussed with reference to a possible solution to overcome
the drawbacks of these methods: the multi-machine approach.
Chapter 6 is dedicated to the description of the databases used for all
the analysis presented in the following chapters. In particular, the statistical
analysis and the data-reduction algorithms that have been needed to build
a reliable and statistically representative database have been discussed in
detail.
The last three chapters contain all the analysis and all the algorithms im-
plemented for the mapping of the operational space, disruption classification
and prediction. In chapter 7 the mapping of the JET operational space
is presented. The first sections deal with projections and data-visualization
with linear projection methods such as Grand Tour (GT) and Principal Com-
ponent Analysis (PCA). In the central part, the same aspects have been taken
into account by exploiting nonlinear Manifold Learning techniques, SOM and
GTM, on the base of which a detailed analysis of the operational space has
been performed. Such analysis, showing the potentiality of the methods, has
been performed, regarding GTM model, through the implementation of a
dedicated tool. Finally, an outliers' analysis and performance indexes appo-
sitely proposed have been considered for evaluating the overall performance
of the mapping.
In the chapter 8 the developed automatic disruption classification for
JET has been described. The chapter is divided in two parts: the first one
describes the classification of disruptions belonging to the Carbon Wall (CW)
campaigns, whereas in the second part the classification of disruptions with
the ITER-like Wall (ILW) is framed in the assessment of the suitability of the
automatic classifier for real time applications, in conjunction with prediction
systems working online at JET. The reliability of the results has been vali-
dated by comparison with a k-NN based reference classifier and through the
recent conformal predictors, with which is possible to provide, in addition to
the prediction/classification, the related level of confidence.
Chapter 9 is dedicated to the disruption prediction at ASDEX Upgrade.
The first part is related to the description of the database and the data-
reduction technique used to select a representative and balanced dataset.
Self-Organizing Map and the Generative Topographic Mapping have been
exploited to map ASDEX Upgrade operational space and to build a disrup-
tion predictor, introducing at the same time their potentiality for disruptions
classification. Furthermore, the use of this two methods combined with a Lo-
gistic model has been proposed to realize a predictive system able to exploit
the complementary behaviors of the two approaches, improving the overall
performance in prediction.

Significance Proteins fold into intricate 3D structures, determined by their amino acid sequences. Different proteins can fold into drastically different structures, and the space of all possible structures appears hopelessly complex. However, this is precisely the space that needs to be described to understand how sequence encodes structure. In this paper, we decompose the set of known protein structures into standard reusable building blocks, which we call tertiary structural motifs (TERMs). Strikingly, we find that only ∼600 TERMs describe 50% of the known protein structural universe at sub-Angstrom resolution. Furthermore, we find the natural utilization of TERMs gives us a means of uncovering sequence–structure relationships. These insights can be harnessed for protein structure prediction, protein design, and other applications. Here, we systematically decompose the known protein structural universe into its basic elements, which we dub tertiary structural motifs (TERMs). A TERM is a compact backbone fragment that captures the secondary, tertiary, and quaternary environments around a given residue, comprising one or more disjoint segments (three on average). We seek the set of universal TERMs that capture all structure in the Protein Data Bank (PDB), finding remarkable degeneracy. Only ∼600 TERMs are sufficient to describe 50% of the PDB at sub-Angstrom resolution. However, more rare geometries also exist, and the overall structural coverage grows logarithmically with the number of TERMs. We go on to show that universal TERMs provide an effective mapping between sequence and structure. We demonstrate that TERM-based statistics alone are sufficient to recapitulate close-to-native sequences given either NMR or X-ray backbones. Furthermore, sequence variability predicted from TERM data agrees closely with evolutionary variation. Finally, locations of TERMs in protein chains can be predicted from sequence alone based on sequence signatures emergent from TERM instances in the PDB. For multisegment motifs, this method identifies spatially adjacent fragments that are not contiguous in sequence—a major bottleneck in structure prediction. Although all TERMs recur in diverse proteins, some appear specialized for certain functions, such as interface formation, metal coordination, or even water binding. Structural biology has benefited greatly from previously observed degeneracies in structure. The decomposition of the known structural universe into a finite set of compact TERMs offers exciting opportunities toward better understanding, design, and prediction of protein structure.

In order to see the dynamics of prey-predator interaction, differential or difference equations are frequently used for modeling of such interactions. In present manuscript, we explore some qualitative aspects of two-dimensional ratio-dependent predator-prey model. Taking into account the non-overlapping generations for class of predator-prey system, a novel consistency preserving scheme is proposed. Our study reveals that the implemented discretization is bifurcation preserving. Some dynamical aspects including local behavior of equilibria, phase-plane analysis and emergence of Hopf bifurcation for continuous predator-prey model are studied. Moreover, existence of biologically feasible fixed points, their local asymptotic behavior and phase-plane classification of interior (positive) fixed point are carried out. Furthermore, bifurcation theory of normal forms is implemented to prove that proposed discrete-time model undergoes Neimark-Sacker bifurcation around its unique positive fixed point. Taking into account the bifurcating and fluctuating behaviour of discrete system, three chaos control strategies are implemented. Numerical simulations are provided to illustrate the theoretical discussion and effectiveness of introduced chaos control methods.


An important condition for improving the efficiency of modernization of contemporary secondary education is to strengthen the innovative nature of pedagogical activity, which leads to the relevance of the problem of the formation of prospective teachers' readiness to innovative activity in the secondary school. The article critically examines different approaches of modern researchers to the assessment of formation of a teacher's readiness to innovative activity and it offers an original, broader, logically built system of criteria and indicators, which can also be used to determine the levels of formation of readiness of students of pedagogical specialties of higher educational institutions to create innovative educational products as an important component of a teacher's innovative activity. It was supplemented by the gnostic criterion, implying the maturity of skills which are necessary for successful innovative activity and by new indicators concretizing other criteria. In addition, the article presents the results of a fairly wide ascertaining experiment, convincing evidence of the interest of both practicing teachers and senior students of higher educational institutions to innovative activity and it also demonstrates the necessity of its special organization at all levels of pedagogical education, which, unfortunately, was not reflected in the Professional standards of the teacher and Federal state educational standard of higher education.


A splenic lobulation interposed between the tail of the pancreas and the left kidney is not uncommon. On prone ultrasonic scans, this variant of splenic configuration must be considered in the differentiation of anterior masses adjacent to the left kidney and masses originating in the tail of the pancreas. Computed tomography is the most sensitive method to use in making this distinction.

The rotational structures of the ν1 and 2 ν1 infrared bands of monofluoroacetylene were investigated. The values B0=0.32374±0.00005 cm-1 and 0.32372±0.00010 cm-1, respectively, were obtained. In addition, the analysis of the fundamental gave α1= (6.85±0.15) × 10-4 cm-1 and D0= (15±3) × 10-8 cm-1. Theoretically, the centrifugal disortion constant was computed to be 13 × 10-8 cm-1. The hot bands accompanying the fundamental were also studied.


With the development of the big data and deep learning technologies, research on predicting human affects in the wild using deep neural networks is being actively conducted. Many researchers use image and audio together to improve the affect prediction performance. However, the synchronization between image and audio data has not yet been achieved. Moreover, many different ways can be employed to annotate human affects, and the annotations in many datasets are not identical. The data cannot be utilized in supervised learning without the annotation of the task to be predicted. This study proposes a multi-task human affect prediction model with multimodal input and knowledge distillation to address the abovementioned problems. We used SoundNet, which was trained to transfer visual knowledge into auditory representations, to extract synchronized auditory–visual representations. Knowledge distillation was applied to utilize all datasets with incomplete labels. This model used image and audio data to predict the valence–arousal, expression, and action units and was validated using the Aff-Wild2 dataset. When auditory–visual synchronized representation was used, the performance improved by 11.83% and 230.16%, respectively, compared to when visual or auditory representation was used alone. When knowledge distillation was applied, the performance improved by 15.38% compared to when it was not. Consequently, the proposed model achieved a 0.95 performance for the multi-task learning task on the Aff-Wild2 test dataset. This performance is equivalent to that of the second place in the 3rd Affective Behavior Analysis in the wild Multi-task Learning Challenge.

Fluorescent spectra and lifetimes have been measured for trivalent chromium ions in KAl(MoO/sub 4/)/sub 2/, Al/sub 2/(WO/sub 4/)/sub 3/, AlNbO/sub 4/, and AlTaO/sub 4/. Because of the polarization effects of the high-valence cations, the crystal fields of the chromium ions have been reduced. Hence the T/sub 2/--/sup 4/A/sub 2/ vibronic transition spectral-peak wavelengths are longer than 800 nm. Because of their strong electron-phonon coupling interactions and rather broad fluorescent peaks, these materials may be useful as tunable infrared laser crystals.
