Double carrier pulse deep level transient spectroscopy was deployed to identify and characterize the recombination centers in GaAsN grown by CBE. Six electron traps, EI to E6, with average energy depths of 0.035, 0.125, 0.160, 0.365, 0.505, and 0.710 eV, respectively below the bottom edge of the conduction band minimum were observed. The DL TS peak heights of E2 and E4 were found to decrease with simultaneous injection of majority and minority carriers in the space charge region. This result is explained by the recombination of electrons and holes via E2 and E4 centers. The recombination processes were confirmed to be non radiative and the possible origins of these two defects were expected to be related to the N-atom. InyGa l.yAsl.xNx alloys are considered as promising semiconductors for ultra-high efficiency tandem solar cell, since their bang gaps gradually decrease with raising the atomic fraction x ofN, without a significant change of lattice parameter. Indeed, with only 3% of N and 9% of In, the resulting alloy is a potential candidate for the lattice-matched tandem Ge (0.76 eV)/lnGaAsN (1.04 eV)/GaAs (1.42 eV)/lnGaP (1.89 eV) cell, which could achieve a conversion efficiency of more than 40% under standard AMO radiation (I). Meanwhile, incorporating a small atomic fraction ofN in the alloy degrades markedly the lifetime and the mobility of both types of carriers (2, 3), which consequently leads to decrease the diffusion lengths and limit the collection of photogenerated carriers in the solar cell device. An obvious reason of such degradation is the formation of active N-related recombination and scattering centers, owing to the large miscibility of the gap between GaAs and GaN, as well as to the smaller atomic size of N compared with its competitor atom for the same V -site. Experimentally, the distribution of the most energy states in the forbidden gap of GaAsN grown by chemical beam epitaxy (CBE), was obtained by deep level transient spectroscopy (DL TS) and double carrier pulse DL TS (DC-DL TS) (4-6). Furthermore, some lattice defects were tentatively identified and their effects on the electrical properties of the material were partially clarified. The most important result related to these defects is the confirmation of the existence of an electron trap, with thermal activation energy between 0.3 and 0.4 eV below the conduction band minimum (CBM), which acts as a strong active N-related nonradiative recombination center (4). It origin was tentatively


This work presents the design and testing of an integrated 8-channel CMOS biopotential recording chip, consisting of low-noise input stages, tunable second stage, a multiplexer, and two analog-to-digital converters (ADC). Through its variable supply concept, the integrated input-referred noise of the first stage is selectable from 1.5 down to 0.63 μVRMS (ISS = 200 μA), which is superior to standard laboratory recording systems. The device features variable lower and upper corner frequencies, and outputs two digital 16-bit data streams at 62.5 kS/s. The chip die was fabricated in X-Fab 0.35 μm CMOS technology and has an area of 10 mm2.


Motor vehicles are a major contributor to air pollution, and the exposure to this human-caused air pollution can lead to harmful health effects. This study evaluates the impact of the provision of point-of-care ultrasounds (POCUS) by primary care (PC) to avoid the patient's need to travel to a specialized service. The study estimates the costs and air pollution avoided during 2019. The results confirm that performing this ultrasound at the point of care reduces the emission of 61.4 gr of carbon monoxide, 14.8 gr of nitric oxide and 2.7 gr of sulfur dioxide on each trip. During the study, an average of 17.8 km, 21.4 min per trip and almost 2000 L of fuel consumed in a year were avoided. Performing POCUS from PC reduces fuel consumption and the emission of air pollutants and also saves time and money. Furthermore, only 0.3% of the scans had to be repeated by radiologists. However, more studies with more participants need to be done to calculate the exact impact that these pollution reductions will have on human health.

The National Environmental Policy Act of 1969 (NEPA) legally mandates extensive use of social science knowledge in governmental decision-making. In so doing, it creates a context for considering problems of social knowledge utilization. Social scientists and policy researchers, while increasingly noting the use (or non-use) of social science in policy, tend to overlook the uncommon dimension to this issue resulting from NEPA's legal mandate for professional social science research. This paper reviews some existing concepts of knowledge utilization, relates them to recent work in applied anthropology, and develops the theme of NEPA's importance as a law mandating social knowledge use. It also suggests that NEPA's legal mandate creates significant opportunities to extend a more effective professional identity for applied anthropology. First, anthropologists working in this area can become familiar with the relevant law and legal scholarship, and contribute to its development. Second, in practice under NEPA,...


Foreign experience is a mechanism through which personal cognitions can be shaped into idiosyncratic characteristics. Under the unique institutional background of China, the purpose of this paper is to examine whether CEOs' foreign experience will affect the performance of CSR and whether the influences of CEOs' foreign experience on CSR vary from the categories of foreign experience or from the governance environments. We find that firms with returnee CEOs show better CSR performance. Moreover, the longer the CEO's foreign experience, the better is the CSR performance. Our results are robust to endogeneity concerns, inclusion of additional control, and alternative measures of key variables. Further analyses indicate that foreign working and integrated experiences have important impacts on CSR performance; and the positive effect of foreign experience on CSR is more pronounced for firms located in better legal environment and for those audited by reputable auditor. Our findings highlight foreign experience of CEO as an important driver of CSR performance.

ABSTRACT Internet of Things (IoT) enabled manufacturing systems can monitor machine health based on real-time data generation, monitoring, control and precise decision-making. In this work, an analytical model-based maintenance scheme is proposed for an IoT-enabled hybrid flow shop (HFS). This model estimates the machine health index by fusing performance metrics data such as cycle time, work in process (WIP) and squared coefficient of variance (SCV) service time. These performance metrics reveal hidden risk factors of the machine's health state. A particular maintenance activity can be proposed before the failure of the machine based on a threshold value of performance metrics data. The proposed maintenance scheme is optimised using interval type-2 fuzzy logic systems (IT2FLSs). The developed model is also validated with a case study in an IoT-enabled HFS.

It is no exaggeration to say that all the problems in translation are connected with language.Therefore,if we want to explore the translation strategies,we should explore the similarities and differences between English and Chinese first and then the translation strategies.


A great nation is not determined by the natural wealth and technology possessed by a nation, but because of the strong character of the nation. Based on this statement, strengthening character education needs to be implemented to support the strengthening of the character of the nation's next generation. Based on a preliminary study conducted in vocational high schools, it is found that many students have low religious character. This is necessary to remember the importance of religious character as a balance to other characters. The final goal to be realized in this study is to develop an android application innovation to strengthen the religious character of Vocational High School students that can be accepted theoretically and practically so that it can be widely used in educational settings as one of the guidance media that aims to overcome the problem of religious character in student classes. The development model used in this study was adapted from the development research model of Borg & Gall (1983). Currently the research process is in stage 3, namely the initial development of the wrong product design, namely developing a scale instrument for religious character. The scale of religious character consists of 28 statement items whose development is based on the religious dimensions of Glock and Strak (1974), namely dimensional beliefs, dimensions of religious practice, dimensions of appreciation, and dimensions of loss and experience. In this article we will build on the validity and reliability of the statement items on the religious character scale. The validity results obtained were in the form of 24 statement items that were declared valid and the instruments were declared valid for use, as evidenced by the reliability value of 0.971 or in the very high category. Based on the results of the validity and reliability, the scale of religious character can be used to measure the religious character of vocational school students

Unlike the Anglo-Saxon countries, where business financing is made through the financial markets, Tunisian banks play a more important role than the financial markets in funding the firms. In addition to their function as lenders, they can participate in the capital of companies and/or serve on their boards. Our results on a sample of 14 listed companies on the Tunisian Stock Exchange (STE) during the 2003/2009 period show that banks play an important role in the governance of the Tunisian firms and affect their performance. Based on this sample, we performed regressions of these two governance variables (banking participation in the firms' equity and boards) on the firms' accounting and stock performance. The obtained results show that, firstly, the banking investment in the firms' share capital has a negative impact on the accounting performance measured by the ROA and the ROE and positively on the stock market performance (Tobin's Q and Marris) and, secondly, the banking presence in the board of directors has both a positive and negative impact on the accounting performance on the stock market performance.


This paper examined multiple engagement supportive strategy (MESS) designed to foster the delivery of Ghanaian language (GHL), focusing on preserving and promoting linguistic diversity in Ghana. Language preservation and revitalization are crucial for the cultural identity and sustainable development of a nation. The MESS strategy integrates multiple engagement components to ensure a holistic and inclusive approach to language delivery. This investigation revealed that there were limited resources and infrastructure, low societal prestige. It was identified that there was limited integration in formal setting. Design adapted for the investigation was descriptive. Qualitative approach was used since extensive figures are not going to be used for the analysis. Interview and focus group discussion were the data collection strategies. In total, three hundred (300) participants were involved for the investigation. Primary source of data was the adapted coupled with readings of the scholar's work. Purposive sampling snowball techniques were used. It emphasizes the importance of collaboration and partnership between key stakeholders. This includes involving local communities, language experts, educational institutions, and governmental organizations to collectively develop and implement language revitalization initiatives. Theoretical framework that underpinned this investigation was socio-cultural theory propounded by Lev Vygotsky (1978). This theory emphasizes the importance of social interactions, cultural tools (such as language, symbols, and artifacts), and the role of more knowledgeable individuals in supporting a learner's development.


The measure of entropy introduced by Shannon [12] is the key concept in the literature of information theory and has found tremendous applications in different disciplines of science and technology. The various researchers have generalized this entropy with different approaches. The object of the present manuscript is to develop a generalized measure of entropy by using the property of concavity. The proposed measure satisfies all essential and some desirable properties of the original Shannon's [12] entropy. Moreover, we have developed a new generalized measure of cross entropy which corresponds to the newly introduced measure of entropy.


Introduction Essential thrombocythaemia (ET) is a disorder characterized by sustained proliferation of megakaryocytes in the bone marrow which results in persistent thrombocytosis (platelet count 450,000 per cu mm or more) with a tendency for complications such as thrombosis or haemorrhage. ET is extremely rare in childhood. A mutation which results in a valine to phenylalanine substitution at position 617 in the Janus Kinase 2 gene is identified in 40 to 60% of patients with ET. We report a 10 year-old boy with persistent thrombocytosis who probably has ET.


Inspired by the works of Ablowitz, Mussliman and Fokas, a partial reverse space-time nonlocal Mel'nikov equation is introduced. This equation provides two dimensional analogues of the nonlocal Schrodinger-Boussinesq equation. By employing the Hirota's bilinear method, soliton, breathers and mixed solutions consisting of breathers and periodic line waves are obtained. Further, taking a long wave limit of these obtained soliton solutions, rational and semi-rational solutions of the nonlocal Mel'nikov equation are derived. The rational solutions are lumps. The semi-rational solutions are mixed solutions consisting of lumps, breathers and periodic line waves. Under proper parameter constraints, fundamental rogue waves and a semi-rational solutions of the nonlocal Schrodinger-Boussinesq equation are generated from solutions of the nonlocal Mel'nikov equation.


With the rapid rise in social network users during recent years, social network is changing business models in the China's Internet industry. Social network produces large amounts of data that reflect the real world, so we can make conclusions about financial incidents by monitoring people's interests in social network and analyzing investors' feelings based on the data. To obtain the data from financial social networks, crawling the web entirely is expensive and unrealistic because of limited resources. A focused crawler that targets a particular topic is more suitable. This paper implements a focused crawler for collecting pages on the financial social network.


In order to further removal the trihalomethanes precursors in reclaimed water during the secondary effluent reuse,the removal and transformation of dissolved organic matter(DOM) in secondary effluent during the granular activated carbon(GAC) adsorption and the laboratory-scale soil aquifer treatment(SAT) was studied.DOM was fractionated with XAD-8/XAD-4 resins into five classes: hydrophobic acid(HPO-A),hydrophobic neutral(HPO-N),transphilic acid(TPI-A),transphilic neutral(TPI-N) and hydrophilic fraction(HPI).The result showed that GAC was preferential in removing HPO-A,HPO-N and TPI-A.The high removal efficiency of HPI during the followed SAT treatment resulted in a higher DOM removal efficiency of 70.1%(which was only 42.1% during the GAC treatment).Up to a 73.1% reduction of THMFP(from 170.96 to 46.53 μg/L) was found for the bulk DOM during the SAT treatment,whereas only a 55.6% reduction occurred during the GAC treatment.The specific THMFP(STHMFP) of HPO-A,TPI-A and TPI-N were decreased efficiently during the GAC treatment,while that of the DOM fractions all showed a converse trend in the followed SAT treatment.HPO-A and HPI were the main THMs precursors of the secondary effluent.The GAC treatment was preferential in adsorbing more HPO-A,while the SAT treatment inclined to remove more HPI.


The feature of exploiting labor force ability in 21st century is to exploit their life-long ability, which includes: ability to use information, technique and ability to make arduous efforts.


Fish swimming results from a complex dynamic balance between drag and thrust force. To better understand the thrust performance and the fluid mechanism of undulatory fish swimming, a biorobotic model that mimic mackerel (Scomber scombrus) was developed. The robotic fish model have been used to investigate the hydrodynamic performance as a function of several principal controllable kinetic parameters: Stouhal number (St), undulatory amplitude (h), body undulatory wavelength (λ) and the caudal fin pitch angle (θ). For each combination of these kinetic parameters, there is a critical self-propulsion towing speed, which was not preset but defined as the threshold value at which the mean net force, measured on the robotic model, becomes zero. We simultaneously measured the power consumption, self-propulsion speed, and wake structure of the robotic swimmer under condition of the self-propulsion. Furthermore, the thrust efficiency was estimated using the vortex dynamic model based on Digital Particle Image Velocimetry (DPIV) technique. Primary experimental results indicated that both the caudal fin pitch angle and the Strouhal number had a significant impact on the propulsion performance and the wake structure. A wedge-like 2P wake structure was observed for most of the kinetic parameter combinations. Although the typical reverse Karman wake structure is commonly observed in many flow visualization tests of the live fishes, it only emerged within the results of a narrow range of robotic caudal fin pitch angles in current experiment, occurring concurrently with enhanced thrust efficiency.


We consider an M/M/1 queueing system with auxiliary service in addition to primary service. When the auxiliary service is requested, the server allocates part of its capacity to process the additional service. We show that the possible optimal auxiliary capacity is actually on the convex envelope of the auxiliary cost function. Also, the optimal control policy is that the allocated capacity for auxiliary service is monotonically non-increasing in the number of people in the system.


Excited halogen atoms in quartet spin states F*(2p43s, 4P5/2), Cl*(3p44s, 4P5/2), and Br*(4p45s, 4P5/2) were produced from helium sensitized radiation chemical decomposition of SF6, CF3Cl, CF3Br, and CF2Br2. Quenching rate constants of these excited halogen atoms by simple gas molecules such as O2, N2, H2, CO, CO2, NO, NO2, N2O, CH4, C2H6, and Xe including parent molecules were determined from absorption decay curves at 685.8 nm for F*, 837.5 nm for Cl*, and 827.4 nm for Br*. The optical densities were assumed to be proportional to (number of excited atoms per one cubic centimeter)0.9. The quenching rate constants obtained here were compared to those reported of metastable rare‐gas atoms and an excited oxygen atom O*(2p33s, 5S2), and further discussed in terms of several theoretical kinetic models.


Vicinal Si(111) surfaces misoriented towards the [211] direction facet reversibly upon cooling through the (1×1) to (7×7) reconstructive phase transition. We have used low-energy electron microscopy to examine the kinetics of this phase separation. Nucleation and growth of facets occur when the surfaces are quenched just below the phase boundary. However, at lower temperatures we find evidence for the existence of a spinodal which divides the faceting kinetics into unstable and metastable regions. The location of the spinodal is consistent with previous measurements of Si(111) step energetics


This research paper describes an investigation into the impacts of a flipped pedagogy on studentperceived classroom climate. We used the College and University Classroom Environment Inventory (CUCEI) to assess the classroom climate in both the flipped class and various control classes that were not flipped. This inventory includes seven psychosocial dimensions of classroom climate: personalization, involvement, student cohesiveness, satisfaction, task orientation, innovation, and individualization. Our specific research questions were: 1. Do students perceive a more positive classroom climate in a flipped classroom vs. a traditional lecture-based course when controlled for course content and instructor? 2. What psychosocial dimensions were most impacted by the flipped pedagogy? 3. What do these results indicate about student motivation in a flipped classroom? One group of students (Group "A") had just completed the flipped course. The second group (Group "B") consisted of students who had just completed the same course, but taught in a traditional format. This was to control for the effect of the course material on student's motivation and interest. The third group (Group "C") consisted of students who had just completed a different engineering course taught by the same instructor in a traditional format. This was to control for a different instructor. The groups were analyzed using a one-way ANOVA. The responses were analyzed based on each of the seven subscales within the CUCEI, as well as on an overall score combining all seven subscales. The results show that overall the flipped class results in a higher score in both overall classroom climate and for the individualization subscale. In addition we found higher averages for task orientation when controlled for instructor. When controlled for the course content, the flipped course is more innovative and students get to know each other more. The implications of these findings on flipped classrooms are important to those faculty wishing to flip their course. How does a flipped classroom impact classroom climate and student motivation?


Inter-harmonics is a kind of the harmonics which are not an integer of the fundamental frequency component. The inter-harmonics, same as the integer harmonics, have serious impacts on the design of harmonics compensation equipments, so it is important to measure inter-harmonics accurately. The interharmonics cannot be achieved accurately by using FFT for an unsynchronized sample sequence analysis because of large errors in such cases. To reduce the errors caused by using FFT for an unsynchronized sample sequence analysis and to improve the measuring precision of interharmonics in electric power system, an interharmonics estimation based on interpolation FFT algorithm is proposed. The estimation algorithm based on Rife-Vincent (Ⅲ) window for the interharmonics parameters is given. This algorithm can make the analysis accuracy improved significantly. Simulation results demonstrate that the estimation interharmonics frequency, amplitude and phase are highly accurate using the improved algorithm for the unsynchronized sample sequence analysis.


The 0/1 knapsack problem is a typical problem in the field of operational research and combinatorial optimization, and it belongs to the NP problem. Research on the solutions of the 0/1 knapsack problem algorithm has very important practical value. This paper first described the 0/1 knapsack problem, and then presented the algorithm analysis, design and implementation of the 0/1 knapsack problem using the brute force algorithm, the greedy algorithm, the genetic algorithm and the dynamic programming algorithm, and compared the four algorithms in terms of algorithm complexity and accuracy. On this basis, the future research directions of the 0/1 knapsack problem were analysed, and we proposed to use the rough set theory to solve the 0/1 knapsack problem. This paper can provide insight for solving the 0/1 knapsack problem and applications.


We propose a new scheme to construct neural networks to classify patterns. The new scheme has several novel features : 1. We focus attention on the important attributes of patterns in ranking order. Extract the most important ones first and the less important ones later. 2. In training we use the information as a measure instead of the error function. 3. A multi-perceptron-like architecture is formed auomatically. Decision is made according to the tree structure of learned attributes. This new scheme is expected to self-organize and perform well in large scale problems.


Although overt expressions of racism are increasingly rare within the sport media, implicit and conscious/unconscious racial bias, on the other hand, is a common feature within contemporary sports reporting. A comprehensive body of research has illustrated that Black athletes are more
 likely to be praised for their supposed innate biological superiority while White athletes are more likely to be credited for their work ethic and intelligence. In addition, Black, Asian and minoritized ethnic athletes, such as Lewis Hamilton and Raheem Sterling, have often been criticized
 for being too 'flashy' by some sections of the UK press, which conjures up images of undeserved riches. These representations are symptomatic of a wider culture in which minoritized communities are 'othered'. This article, then, focuses on one example of racial bias
 from BBC Radio Derby's Sports Scene podcast from February 2020. Former professional footballer turned pundit, Craig Ramage, suggested that 'all the young Black lads' needed 'pulling down a peg or two' and needed to work harder. This work empirically investigated
 three online post titles across Facebook, Instagram and a forum to critically examine how contemporary football audiences reacted to such comments. The analysis illustrated that online participants were: (1) divided over whether Ramage's comments were racist or not, (2) unsure of who
 was to blame, (3) unsure of who the victim was. The article concludes by outlining preventative measures to avoid such reoccurrences and emphasizes the importance of educational training around equality and diversity within the sport media.


Larvae and fry of 12 fish species (smelt, perch, bream, roach, ruffe, pikeperch, silver bream, ide, rudd, golden carp, bleak and three-spined stickleback) were identified in the aquatic part of the Curonian Lagoon during the studies of ichthyoplankton conducted at the end of May or at the beginning of June and at the beginning of July 1996–2002. Among them, perch, smelt and bream larvae dominated in the Curonian Lagoon. The highest densities of smelt, perch and bream larvae were recorded in 1997, whereas the highest density of roach larvae was found in 1999. However, in July, densities of ichthyoplankton were much lower than at the end of May or at the beginning of June. We also recorded a tendency towards decline in the density of smelt larvae and a tendency towards increase in the density of roach larvae. Smelt larvae migrate mainly from their spawning areas to the Baltic Sea through the eastern part of the Curonian Lagoon. The size of larvae depended on the beginning of the spawning period and water te...

Plants grown from injected cuttings are much inore seriously affected than those irzfected later bji the whitejly vector (Bemisia tabaci) and plants infected at a late stage of crop growth are almost unafected. Positive relationships Izave been established between the extent and severity of the leaf symptonis and yield loss, but losses can be considerable, even in varieties designated as resistant. Tlie limitations of these studies are discussed and emphasis is placed on tlze need for additional irzfonnation on the effects of ACMV on the yield of the improved virus-resistant varieties now available. Data are also required on possible conzpetition and coinpensation effects within nzixed stands of infected arid uniizfected plants at different sites, spacings and levels of soil fertility.


The three-dimensional flow field in a helical intake port was numerically simulated using CFD software Fire for a practical engine to analyze how the gradient, up and down deviations affect the performance of the helical intake port. The result calculated in Fire is in good agreement with that gotten by port rig test.


ABSTRACT Perceived similarity is influenced by both taxonomic and thematic relations. Assessing taxonomic relations requires comparing individual features of objects whereas assessing thematic relations requires exploring how objects functionally interact. These processes appear to relate to different thinking styles: abstract thinking and a global focus may be required to explore functional interactions whereas attention to detail and a local focus may be required to compare specific features. In four experiments we explored this idea by assessing whether a preference for taxonomic or thematic relations could be created by inducing a local or global perceptual processing style. Experiments 1–3 primed processing style via a perceptual task and used a choice task to examine preference for taxonomic (versus thematic) relations. Experiment 4 induced processing style and examined the effect on similarity ratings for pairs of taxonomic and thematically related items. In all cases processing style influenced preference for taxonomic/thematic relations.


Local exhaust ventilation systems have become the most popular choice for capturing and containing releases of gas-borne dust contaminants in various fields of human activities. Energy conservation techniques have to be developed for these systems while ensuring that their contaminant capture efficiency is not compromised. This study summarizes our developments in the field of energy-saving techniques relying on the properties of detached, twisted and recycled flows of dust-laden air.

A relatively simple experimental technique is proposed and demonstrated for making measurements of absolute dewpoints and relative deposition rates from flowing combustion gases containing condensible inorganic vapors (here alkali sulfates). In using this "flash evaporation" technique, one first accumulates an inventory of condensate on a Pt-ribbon target maintained below the dewpoint and then flash-evaporates this condensate inventory into the filament wake, where its alkali content is monitored by alkali-atom emission spectroscopy. As implemented here, this method is shown to have a number of important advantages over more time-consuming alternatives (e.g. gravimetric) or demanding alternatives (e.g. optical reflectance interferometry or ellipsometry-). In particular, the flash evaporation technique can also detect liquid condensate inventories which are small enough to be negligibly influenced by surface run-off produced by inevitable gas-side shear stress and liquid condensate surface tension gradient...


This paper will discuss commercializing discoveries made at research organizations, particularly with a view to the In re Kubin case, decided April 3, 2009, by the Federal Circuit. Here, the existence of a general method of isolating DNA molecules was held to be relevant to the question whether the DNA molecules themselves would have been obvious under § 103 of the patent act. How are DNA inventions patented anyway? What does it take for academic research to reach patients? How might the decision of In re Kubin effect research commercialization and technology transfer? Introduction In re Kubin, decided by the U.S. Court of Appeals for the Federal Circuit on April 3, 2009, substitutes the old rule on awarding patents for DNA research with a new one.1 Specifically, the existence of a general method of isolating DNA molecules is now relevant to the question of whether the DNA molecules themselves would have been obvious under 35 U.S.C. § 103. With the commercialization of biomedical discoveries made at academic or basic research centers being highly dependent upon patents to protect the substantial investment of risk capital for product development, will this new rule adversely affect those technologies based upon DNA —technologies at the forefront of today's molecular medicine? Patent Primer for DNA Inventions One of the judges of the three-judge panel that decided Kubin sensibly requested the advocates during oral argument to state their positions in a way that he could understand because he humbly admitted that he lacked a scientific background.

The backend optical assembly module for a space-based, laser communication terminal is presented. The backend optical assembly utilizes voice coil-fast steering mirror technology embedded into a control loop that both provides terminal-level pointing capability, and maintains receive channel fiber coupling. The fast steering mirror technology presents a technical solution for operating within the space environment, while simultaneously meeting the bandwidth requirements for characteristic satellite vibration profiles. The system's architecture design meets the demands of onplatform, jitter-rejection performance to establish and maintain a communication link.


Samples of La2-xBixCuO/sub 4/ were prepared by codecomposition of the nitrates in air. Single phase products were obtained for x < or = 0.10. The substitution of bismuth for lanthanum resulted in an increase in delocalization of holes, as indicated by increased conductivity and a decrease in the Neel temperature. Samples were also annealed in argon at 600 C and their properties compared with the samples as prepared in air.


Nowadays, high dynamic range imaging techniques are often applied for outdoor applications that may encounter scenes with an extremely high dynamic range. In such scenes, a halo can be produced by gradient reversal, and color information is easily damaged. In this paper, we propose an exposure fusion algorithm that does not suffer from any artifacts in extremely high dynamic range scenes. Using the HSV color model, gradient reversal is suppressed in the Value component, and color information is preserved in the other components. Experimental results show that these two artifacts are effectively avoided, and all of the scene's details are preserved.


Most of Focus Context visualization methods differentiate the magnification unit only by simply assigning each voxel/cell with an importance value while ignoring the shape content embedded in the volume data. In this paper, we take the volumetric structure information as important cue to facilitate Focus Context visualization, which can homogeneously or non-homogeneously scale the volume data in a structure-sensitive way.


Instructional material evaluation is crucial to the development of curriculum and instructional materials.The instructional material evaluation system of Oklahoma State is very typical in US's instructional material evaluation.Compared to other state,it is special in construction and characterized with emphasizing the integrity of whole system,the content and teaching attribute of textbooks,and students'learning.Its evaluation ideas have great inspiration to the instructional material evaluation system of China on relationships between administration and instructional material evaluation system,evaluation members,content and emphasis.


The present study evaluated the effect of packaging (air, vacuum) with or without addition of sodium acetate (2% W/V) on shelf-life extension of rainbow trout (Oncorhynchus mykiss ) under refrigeration, for a period of 18 days. Four different treatments were tested: CAP: control air pack; SAAP: sodium acetate treated aerobic packaging; VP: vacuum packaging in the absence of sodium acetate; and SAVP, sodium acetate under VP. Trimethylamine nitrogen (TMA-N), free fatty acids (FFA) and peroxide values (PV) of SAVP samples were lower compared to the other treatments during the entire refrigerated storage period. In the present study, the thiobarbituric acid (TBA) level showed fluctuations during storage indicating that TBA values may not reveal the actual rate of lipid oxidation. Total viable counts for fresh rainbow trout stored aerobically exceeded 7 log CFU g -1 after 10-11 days, while treatments SAAP and VP reached the same value on days 12 and 16, respectively. In contrast, SAVP samples did not reach this value throughout the 18-day. Psychrotrophic counts of SAVP samples were significantly (P < 0.05) lower compared to the control samples during storage period. As regards sensory evaluation, shelf-life of trout was longest for SAVP (15-16 days), followed by VP (12-13 days), SAAP (9-10 days), and CAP samples (6-7 days). The results indicated that the combined effect of vacuum packaging and sodium acetate on fish samples preserved their good quality characteristics and extended the shelf-life of the treated samples during refrigerated storage, as supported by the results of microbiological, chemical, and sensory evaluation analyses.


To improve the heat resistance and wear resistance of coppery elements,the Al2O3/Cu composite material was prepared by internal oxidation of deeply aluminized pure copper matrix.The microstructures and properties of the composite material were studied.The results show that the grain-abrasion resistance and adhesive wear resistance is 1.85 times and 9.4 times that of copper respectively;the thermal fatigue resistance of the composite is higher than that of copper,the weightlessness of thermal fatigue sample is 0.88% of that of copper.The specialty makes the Al2O3/Cu composite material by internal oxidation of deeply aluminized pure copper matrix is more fine to be the diathermanous copper material of metallurgical equipment in the high temperature service condition than the ageing and solution alloy of aluminized deeply pure copper.

SUMMARY 1. Two cases of lobectomy for pulmonary infarction simulating bronchogenic carcinoma are reviewed. 2. In both cases the signs, symptoms, x-ray and bronchoscopy findings were similar to those commonly seen in pulmonary malignancy. 3. In its protean manifestations, pulmonary infarction may mimic almost any other lung disease. 4. It occurs more in the ambulatory patient than is generally realized. 5. Despite the occasional unnecessary pulmonary resection, one should not deter from exploratory thoracotomy on all undiagnosed, suspicious, pulmonary lesions.


Introduction: Any dysfunction of the auditory system can lead to communication problems and difficulty in adapting with environment. The main aim of the study was to determine the prevalence of hearing disorders in 3-6 years old kindergartens in the city of Hamedan, 2012. Materials and Methods: In this cross-sectional study, three hundred and forty five subjects (185 female, 160 male) were selected by random sampling. After filling in the form of hearing loss awareness by parents and educators, Otoscopy (ear examination), immittance test, and pure-tone screening was implemented. Results: Our results showed that there were %11.6 abnormal ear canal anomalies, %22.6 tympanic membrane disorder, %22.8 atypical tympanogram, %28.7 non acoustic reflex and %11.9 hearing loss Consisted of 10.3 conductive hearing loss, 1.3 sensory-neural hearing loss and 0.3 mixed hearing loss. About %11.9 of involved children had a mild to moderate hearing loss and no severe or profound one was observed between them. Ninety six (%27.8) and 6 (%3.7) children required intervention and rehabilitation training program, respectively. Parents (%2.3) and educators (%1.6) awareness of hearing loss was in low level. Conclusion: According to the high percentage of children in need of treatment and the impact of hearing disorders on learning in early childhood; auditory rehabilitation programs, keep parents and educator's informed and early periodic auditory screening are strongly recommended.


Research on compliance of tourists to guidelines in Antarctica has been limited. This investigation explores if the current reporting methods sufficiently provide an accurate measure of tourists' noncompliance. Specifically, the study addresses the compliance knowledge gap regarding
 Antarctic tourist behaviors by documenting instances of noncompliance with the General Guidelines for Visitors to the Antarctic (GGVA) to determine if the Antarctic Treaty Inspection Program (ATIP) and industry reports accurately reflect the frequency of noncompliance in the Antarctic. Conducted
 in situ at four landing sites along the Antarctic Peninsula, documented instances of noncompliance occur at a frequency of 1.63 instances per minute ashore. Based on available data from the ATIP and the International Association of Antarctica Tour Operators, this frequency of noncompliance
 challenges the status quo and implies that further investigation is necessary.


Drawing on a larger study that initiated a dialogue about race and inclusion, the author examined the challenges and responsibilities of White women in higher education leadership through the lens of critical race theory. Though there is a need for women, from a feminist perspective, to confront the trend that higher education leadership continues to be White and male, there is more so a need for White women to interrogate the normative and oppressive nature of Whiteness. Because Whiteness is said to be overlooked within the narrative of feminism, White women are accused of perpetuating racism. Yet, very little research explores what happens when White women, particularly in higher education leadership, interrogate Whiteness. Contributing to the bodies of research on feminism, racism, Whiteness, and leadership within the context of higher education, the author presents strategies that could address the polarizing effects of feminism; discusses implications that go beyond institutional type; and provides directions for future research.


Ignorance about political related issues has long been considered a threat to democracy. This paper revolves around the concept of political ignorance, focusing especially on Ilya Somin's book Democracy and Political Ignorance and going beyond his standpoint in two ways. First of all, it moves away from the notion of factual knowledge by showing that political ignorance cannot be limited to a matter of information quality. On the contrary, it shows that ignorance concerns the formation of opinions about political facts, which are the bricks with which disagreement is built. Then, using the insights of the Moral Foundation Theory by Jonathan Haidt and his colleagues, the paper argues that moral intuitions represent an additional source of bias that current research on the problem of voters' ignorance should address. While Somin argues that biased moral values are the outcome of ignorance, Moral Foundation Theory suggests that moral intuitions are a robust determinant of people's political views as they make factual knowledge partially irrelevant and also make people with different moral minds unable to understand the basis of reciprocal factual argumentations.

A data processing apparatus includes a microprocessor which processes data and outputs m bits of data simultaneously and a semiconductor chip module. The module has a plurality of memory chips having data width of n bits data formed on each side of a substrate. The apparatus further includes data lines connected to the microprocessor and the memory chips for slicing m bit data into n bit data and providing the sliced n bit data to each memory chip. The data of a data processing apparatus is transmitted by the microprocessor and the memory chips. The microprocessor outputs an address signal to the memory chips. One group of the memory chips outputs data upper n bits to the microprocessor in parallel based on the address signal. The other group of the memory chips outputs data of lower (m-n) bits to the microprocessor in parallel based on the address signal.


Recent studies have indicated a negative association of strontium (Sr) in the drinking water with caries prevalence (Meyerowitz et al., Caries Res 13:203, 1979). However, previous animal studies have shown equivocal results of the effect of SrC12 on dental caries and have given little information on uptakes. One reason for these equivocal results may have been the variation in the type of Sr salt used, such as SrSO4, SrC12, and SrCO3. Variations in caries effects for different salts of a trace element have been noted before (Jenkins, Brit Dent J 1 22:435, 1967). Accordingly, an experiment was carried out using rats to test the effects of Sr s4lts on caries (to be reported later) and also to stAidy the uptake of Sr and fluoride by the rat enaMel. The salts were the oxide (SrO), sulfate (SrSO4), nitrate (Sr(NO3)2), chloride (SrC12), lactate (Sr-lactate), and fluoride (SrF2). They were administered via the drinking water at concentrations to give 50 mgSr /l. The carbonate (SrCO3) proved too insoluble for use. Details of rat's age, strain, diet, and housing and all methods used for the experiment have been described before (Meyerowitz et al., Caries Res 13:203, 1979). While post-eruptive administration (from day 19 to day 65) was, via the drinking water ad libitum, pre-eruptive ajiministration (from day 3 to day 19) was by esophpgeal intubation.


The stiffness of cell membranes is a crucial functional property of cells and an indicator of disease. An imaging technique called quantitative phase imaging (QPI) allows high-resolution observation of the stiffness of living cells and could eventually lead to enhanced treatment and diagnostics for conditions such as malaria, sickle-cell anemia, and cancer. This technique is being developed by scientists at the G. R. Harrison Spectroscopy Laboratory at MIT. Unlike most current methods for studying cells, QPI enables monitoring of living cells during time intervals from milliseconds to days. That makes it an excellent method for studying cellular processes. Eventually, it should even be possible to create 3D movies of the internal workings of cells. QPI reveals every vibration of red-blood-cell membranes. That, in turn, makes it possible to infer the elasticity of the cells, which is crucial for their function: they need to be able to fold and squeeze through tiny capillaries. QPI has revealed the membrane tension of red blood cells,1 previously measurable only by contact techniques such as micropipette aspiration. This kind of information is relevant to infection with malaria, for example, which significantly increases the stiffness of red blood cells. Other diseases coming under the QPI microscope at MIT are alcoholism and sickle-cell anemia. QPI promises to provide both a better understanding of these diseases and a noninvasive tool for drug testing. Eventually the technique could form the basis of a high-throughput screening system for various blood-related disorders. Scientists have long been able to peer into cells using electron microscopy, which offers a much higher magnification than a traditional light microscope. But because electron microscopy can only be used on cells that are dehydrated, frozen, or treated in other ways, it cannot be used to view living cells. QPI requires no sample preparation or contrast agents, and can be fully automated. Figure 1. A droplet of blood, as seen by quantitative phase imaging. The characteristic 'Life Savers' shape of red blood cells can be quantified with nanometer accuracy.


Craspedacusta sowerbii (Lankester, 1880) is a cnidarian thought to originate from the Yangtze River valley in China. However, C. sowerbii is now an invasive species in freshwater systems worldwide. In Chile, C. sowerbii was first recorded in 1942 by Porter and Schmitt in the Marga-Marga Reservoir, in Valparaíso. Since then, there have been few further Chilean records of this species. Here, we report the presence of C. sowerbii medusae in Santa Elena Lake, Bulnes, Región del BíoBío, along with limnological parameters.


The Scientific Knowledge for Indian Learning and Leadership (SKILL) precollege college program of the South Dakota School of Mines and Technology concluded the 1994 PREP program on July 22, 1994. The program graduated 22 students from the 4-week residential math/science program for American Indian students. Primary academic focus was physics (30 hours); each student was given a bicycle to solve problems on angular momentum and mechanical advantage. Mathematical calculations and problem solving exercises were done in mathematics class (20 hours). Preliminary results in math, physics, and geology show dramatic increases in student achievement over the 4- week period. The program paired every two students with a faculty member or research scientist, and each team completed a research project.


Abstract From accident investigations it is found that under some unknown conditions the energy absorbing capacity and anti-overriding function of anti-climber are greatly reduced due to the serious vertical buckling. In order to analyse the vertical buckling mechanism of collided anti-climber, a simulation strategy based on the coupling finite element method and multi-body dynamics is proposed in this paper. A numerical model of anti-climber is established and validated with the quasi-static crush test. The simulation results indicate that in some train collisions the maximal overriding speed can increase as large as 1.5 m/s. Under this condition, large constraint force and bending moment are induced and applied on the collided anti-climber, resulting in a serious vertical buckling. Besides that, the initial vertical offset is identified as another important factor. Generally speaking, the buckling degree as well as the deterioration of energy absorption capacity of collided anti-climber becomes more severe with the increase of initial offset. Moreover, when the two factors (initial vertical offset and overriding speed) are coupled together, the crush behaviour of anti-climber is more complex. If the bending moments, which are induced by the initial vertical offset and overriding speed respectively, are in the same direction, the collided anti-climber is buckled seriously. On the other hand, if these bending moments are in the opposite directions, they are counteracted. As a result, the collided anti-climber is buckled less seriously and has more capacity to absorb the collision energy.


A preliminary study of gas-cooled natural uranium power reactors moderated by heavy water and a compsrison of them with a similar reactor cooled by heavy water have shown that a reactor cooled by helium holds sufficient economic promise to merit further study. The results indicate that helium cooling might give a lower cost for power by about 10%. However, many other developments must be made in the design of reactors in order to reduce the cost of electrical power from atomic energy to an economical zone of 4 to 6 mills per kwh. The data were generated for the purpose of guiding the over-all research program relating to the production of low cost power from heavy-watermoderated atomic reactors. (auth)


This article surveys seventeenth-century narratives about 'wonders', 'marvels', 'prodigies', 'providences', and 'remarkables' and the scholarship that has treated them. Over the past 25 years, narratives about wonders and providences have played an increasingly important role in literary scholarship, the history of science, the history of the book, and the history of popular culture (and especially popular religious culture). The article considers the forms, meanings, and public roles of these 'remarkable' texts, and also discusses the scholarly movements that have led to their current prominence in the secondary literature. Although the article limits its focus to early modern texts produced in England and colonial America, it includes a wide range of print formats in which marvels and providences appeared, including cheap print formats such as broadsides and broadside ballads, almanacs, news pamphlets, and early chapbooks; as well as learned texts such as early natural philosophy (science) journals and anthologies published by ministers. The article opens by outlining the nexus of philosophical, political, and cultural developments that prompted an expanded interest in wonders, prodigies, and remarkables among both learned and common people in the period. It then explores the textual corpus itself and the varied rhetorical uses to which wonders were put by writers, publishers, and readers, using the history of Mary Dyer's monster birth for illustration. Finally, it examines the secondary scholarship on these texts.


In 1889, R. Marie, examining patients at the Paris Bureau central d'admission, came to the unexpected result that hysteria is encountered very often in the lower classes of society and, moreover, much more often in men than in women. A little later, this result was confirmed by Souques' hospital observations.


Mary Magdalene's conversion to Christianity must have been a turning-point of paramount importance in her life. This chapter explores the relationship between text and image, in relation to the portrayal of Mary Magdalene in the Late Middle Ages and the Renaissance in the Western World, and more specifically with regards to portrayals of her conversion. It briefly introduces the complex legendary persona of the Magdalene as it emerges from biblical texts, as well as later legends. The reception of specific aspects of the Magdalene's legend in both high and low culture becomes clear through the presentation of her conversion in both popular theatre and more elitist manifestations in the visual arts. It is a well-known fact that in the Western tradition, Mary Magdalene as a 'literary' character is the result of a fusion of several biblical and legendary figures. Keywords: Christianity; Late Middle Ages; Mary Magdalene's conversion; Renaissance


In the linear digital filter theory for calculation of Hankel transforms it is possible to find explicit series expansions for the filter coefficients. A method is presented for optimizing the Hankel filters calculated in this way. For a certain desired accuracy of computation, the sampling density and filter length are minimized by choosing the parameters determining the filter characteristics according to the analytical properties of the input function. A new approach to the calculation of the filter coefficients has been developed for these optimized filters. The length of the filters may be further reduced by introducing a shift in the sampling scheme.


Grebes eat feathers, but the function of feathers in the alimentary tract and the digestion of feathers are poorly understood. In this article, we isolated Bacillus subtilis, a bacterium with strong featherdegrading ability, from the alimentary tract of grebes; we further purified a secretory keratinase with a molecular weight of 42KDa from B. subtilis. The optimal pH of the keratin-degrading reaction was 6.5, which exactly was the pH value in the alimentary tract of grebes. The feathers eaten by grebes can protect wall of the stomach. The feather net in the third chamber of the stomach could filter food and prevent petrous food such as bones from entering the alimentary track. Importantly, feathers could be digested by feather-degrading bacterium to supply the specific amino acids (cysteine and cystine) after fulfilling their protection function. It was suggested that the digestion of feathers in the alimentary tract of grebes was accomplished by the keratin-degrading bacteria.


This paper explores issues concerning personal agency in discursive psychology and discourse analysis, with a particular emphasis on agency in terms of motivational accounts of the person. Issues are discussed in relation to the efficacy, acceptability, and accessibility of discourse analytic research for the practising psychotherapist. We suggest that such an approach may raise problems in four areas. First, we argue that without explicit theorization of the subject as language user, discourse analysis may be vulnerable to the charge of determinism. Second, theorization of the subject as language user may be required to account successfully for individual consistency and continuity of identity. Third, although claiming to critique commonsense notions of subjectivity, implicit dualist assumptions facilitate a reading of discursive psychology that is compatible with a motivational model of the person. Finally, we argue that discursive psychology itself implies a particular model of the strategically motivated language user. We conclude that, although these issues require clarification, discursive psychology and discourse analysis have much to offer psychotherapy research.

Currently, this type of waste does not generate benefits beyond its sale to the pig breeding industry for the fattens them, obtaining a price of no more than $ 0.03 MXN; This project proposes a use giving added value, attending to a food crisis problem with product innovation, as well as avoiding discarding said serum contaminating the water.


A theory of pulsar radio emission generation, in which the observed waves are produced directly by maser-type plasma instabilities operating at the anomalous cyclotron-Cherenkov resonance ω − k‖v‖ + ωB/ γres = 0 and the Cherenkov-drift resonance ω − k‖v‖ − k⊥ud = 0, is capable of explaining the main observational characteristics of pulsar radio emission. The instabilities are due to the interaction of the fast particles from the primary beam and the tail of the distribution with the normal modes of a strongly magnetized one-dimensional electronpositron plasma. The waves emitted at these resonances are vacuum-like, electromagnetic waves that may leave the magnetosphere directly. In this model, the cyclotron-Cherenkov instability is responsible for core emission pattern and the Cherenkov-drift instability produces conal emission. The conditions for the development of the cyclotron-Cherenkov instability are satisfied for both typical and millisecond pulsars provided that the streaming energy of the bulk plasma is not very high γp ≈ 10. In a typical pulsar the cyclotron-Cherenkov and Cherenkov-drift resonances occur in the outer parts of magnetosphere at rres ≈ 10cm. This theory can account for various aspects of pulsar phenomenology including the morphology of the pulses, their polarization properties and their spectral behavior. We propose several observational tests for the theory. The most prominent prediction are the high altitudes of the emission region and the linear polarization of conal emission in the plane orthogonal to the local osculating plane of the magnetic field.

From his valuable writings,4 few fragments only survived plenty of wisdom and originality, which were mostly cited and incorporated in the manuscripts of a substantial number of other philosophers and early Christian authors.5 Heraclitus's expressive style is characterized by density, opacity, resonance, metaphor, symbolism, axioms, critisism and solemnity. Thus, many of his fragments might be interpreted under various viewpoints. Nevertheless, Heraclitus is one of the most extensively studied, cited, esteemed, respected, and even admired preSocratic philosophers, who have had a great impact on the philosophy and the literature for ages,6 given that his doctrines were gaining the admiration of Plato, Aristotle, Stoics,7,8 Sextus Empiricus, Porphyrius, St. Augustin,9 Hölderlin, Hegel,10 Kierkegaard,11,12 Nietzche,13 Heidegger,14,15 Jung, Eliot,16 Ibsen, Kafka17 and many others.


The synchronized flow of Kerner and Rehborn tends to cover a two-dimensional region in the flow/density plane, and is therefore incompatible with the classical kinematic-wave model. It is shown that nonetheless the three states of synchronized flow described by Kerner and Rehborn are compatible with a diffusively corrected kinematic-wave model.


In this paper comparative evaluation of temperature regulated pulse and reflex charging is carried out to comment on the suitable method for fast charging of a Valve Regulated Lead Acid (VRLA) battery. Electro-thermal model of the battery is used as an estimator to measure associated variables such as instantaneous battery current, terminal voltage, state of charge, charge deposited and temperature. Width of the charging pulse has been varied as per the estimated temperature to keep the battery temperature regulated. It is noticed that for both the cases faster charging can be achieved with an increase in temperature reference. It is demonstrated that pulse charging strategy improves the charging speed 10% more than reflex charging strategy.


Research on e-commerce in Malaysia is developing, especially amongst the manufacturing small and medium-sized enterprises (SMEs), as it includes questions about the adoption of business-to business (B2B) e-commerce. Manufacturing SMEs accounted a large portion of gross domestic product (GDP) and SMEs exports. Previous scholars from the developed countries had conducted several research on these issues compared to the developing countries, especially Malaysia. The Balanced Scorecard (BSC) was used to measure the company's performance from four different perspectives. Strategic agility as a moderator should be attributed to the adoption of B2B e-commerce to improve business performance. Strategic agility plays a vital role in technological change, which can improve business performance. The study obtained detailed information on the respondents through the 49th edition of the Federation of Malaysian Manufacturers (FMM) Industry Directory. Three hundred and eighty-one Malaysian manufacturing SMEs participated in this study. The collected data used the online survey methods and Smart Partial Least Squares Analysis (SmartPLS) under the Structural Equation Modeling (SEM). The BSC's point of views include that financial, customers, internal processes, and learning and growth had a significant impact on the adoption of B2B e-commerce. The results showed that strategic agility governed the relationship between B2B e-commerce and internal processes.


Positive solutions of fourth-order nonlinear difference equations with a deviating argument are investigated. We present a classification of nonoscillatory solutions which is based on their asymptotic behaviour and we give necessary and sufficient conditions for the existence of the so-called minimal and maximal solutions.


Magnetic depopulation of hybrid magnetoelectric one-dimensional subbands is investigated within a model for a cylindrical quantum well with either a parabolic or infinitely steep confining potential. A criterion of the number of edge states is derived, which is found to be in good agreement with experiments. Our model also provides a quantitative description of the experimental observation of the damping effect of the state-density oscillations in the presence of a strong axial magnetic field. We make a specific prediction for the dependence of the critical magnetic field ${B}_{c}$ for the onset of the damping effect on the effective radius of the quantum wire, which is amenable to experimental verification.


Malaria is one of the health problems in the world and in Indonesia. This disease is caused by theprotozoan parasite, the genus Plasmodium. Plasmodium falciparum is the most important parasiticdisease with high morbidity and mortality in the world and tropical countries such as Indonesia inparticular. This study aims to determine the activity of sampare leaf extract in inhibiting the growth ofthe FCR-3 strain of the P. falciparum parasite which causes malaria.

In this paper, we present a data-driven micro-states based complex network analysis on cortical surface data to understand the connectives in modeling elicited emotion. In particular, we focus on processing arousal in identifying the differences and similarities between males and females. Micro-states are transient, patterned, quasi-stable states of a time series (e.g., Electroencephalography recording) that allows visualizing dynamic coupling and possibly time-varying levels of correlated or mutually informed activity between brain regions. To obtain cortical surface data from EEG recording, we use source localization method from Brainstorm. We adopted t-distributed stochastic neighbor embedding (t-SNE), for better visualization and finding the optimal number of clusters using different algorithms (e.g., Gaussian Mixture Models(GMM), K-means, etc). Centroids of these clusters are considered as micro-states. We used Hidden Markov Model (HMM) to compute the transition probabilities among micro-states. Subsequently, p-values on graph theoretic measures (e.g., modularity, small-worldness, etc) computed from micro-sites were used to determine the significantly distinguishable, highly segregated and densely integrated network of brain connectivity. Empirical analysis using DEAP dataset reveals that males and females have mostly complimentary micro-states with some commonalities. Males are more likely to stay in specific stable state and females are more likely to stay in transient states. Both groups utilize highly segregated and densely integrated network structure among brain regions in processing arousal.


A simultaneous extinction-ratio enhancement and frequency stabilization scheme is proposed for directly modulated DFB lasers at the optical line terminal to enhance signal quality and to stabilize optical frequency by using a single Fabry-Perot etalon.


Article history: Received: 20 April 2020 Accepted: 10 November 2020 Available Online: 2 April 2021 This paper proposes a new dispersion-convection-reaction model, which is called the gKdV-Fisher equation, to obtain the travelling wave solutions by using the Riccati equation method. The proposed equation is a third-order dispersive partial differential equation combining the purely nonlinear convective term with the purely nonlinear reactive term. The obtained global and blow-up solutions, which might be used in the further numerical and analytical analyses of such models, are illustrated with suitable parameters.


A description is given of a 3.66 m diameter nonfurlable conical mesh antenna incorporating the line source feed principle recently developed. The weight of the mesh reflector and its support structure is 162 N. An area weighted RMS surface deviation of 0.28 mm was obtained. The RF performance measurements show a gain of 48.3 db at 8.448 GHz corresponding to an efficiency of 66%. During the design and development of this antenna, the technology for fabricating the large conical membranes of knitted mesh was developed. As part of this technology a FORTRAN computer program, COMESH, was developed which permits the user to predict the surface accuracy of a stretched conical membrane.


At the recent 1999 World Athletics Championships in Sevilla, Spain, Canada's Bruny Surin matched Donovan Bailey's National and former World Record 100 m mark of 9.84 s. The unofficial times for each, as read from the photo-finish, were 9.833 s and 9.835 s respectively. Who, then, is the fastest Canadian of all time? A possible solution is offered, accounting for drag effects resulting from ambient tail-winds and altitude.


M-Learning has been practiced for decades with success research results in various fields and levels. In order to enhance the quality of instructional activities in terms of students' learning motivation, human association, as well as the linkage between the students and the learning context and materials, instructional pervasive gaming (IPG) is integrated as the approach. This paper draws a learning model of IPG design by synthesizing several valuable theories and shows an exemplary research design as the reference for IPG developers.


The study was conducted on reproductive performance of Bhagnari cattle maintained under semiintensive management condition at Usta Mohammad Cattle Farm, Baluchistan. The data was collected on eighty four adult Bhagnari cows, selected on the performance record and utilized for this study. The results revealed that the mean age at puberty was recorded as1154.179±53.48 days and age at first calving was 1462.024±59.38 days. The calving interval was recorded as 437.59±16.91 days, service period 158.71±17.01 days and postpartum estrus period 135.94±11.87 days. The mean milk yield was recorded 785.78±14.53 liters per cow, which was increased from first to 4 th lactation. The calving intervals, service period and post-partum estrus was found decreased from 1 st to 5 th parity. The difference between the parity was non-significant (P>0.005) for calving interval, postpartum period, service period and milk yield. The reproductive performance and milk yield was found very low, which needs to be improved by improving management practices and out-crossing or cross breeding program on scientific line.


The human colon contains one of the most complex bacterial ecosystems known. At least 400 distinct species of bacteria are represented, although 15 major species account for nearly two-thirds of the isolates (1). The concentration of bacteria in the colon is very high, about 1010 per gram wet weight. Approximately onethird of colon contents is bacteria (1). The bacterial flora of the colon is presumably in equilibrium with its human host. We assume that this equilibrium is a dynamic one because the composition of the host's diet and the physiological state of the host can change. We also assume that the predominant species of colon bacteria are uniquely adapted to survive and flourish in the colonic environment. However, little is known either about the specific features of the interaction between host and flora or about the particular characteristics that are most important for the survival of organisms in the human. To understand how colonic bacteria interact with their human host, we need to be able to answer three types of questions: First, which species of bacteria are found in the colon; i.e., what is the species composition of the colonic flora? Second, what are the bacteria in the colon actually doing; i.e., what are their metabolic activities? Third, where are the bacteria located; i.e., what is their environmental niche? To date, most research has focused on the first of these questions, despite the fact that answers to the last two questions are actually more important for understanding the interaction between the microbial flora and its host. The purpose of this review is to summarize recent research on the composition and activities of the colonic flora and to assess what progress has been made toward being able to answer all of the questions outlined above.


There has been no agreement so far as to what is the ultimate criterion of translation. The shift of our attention from the principle of equivalence to the principle of readers" response indicates that the source text is no longer the only standard on the basis of which we make a final judgment on the target text. The school of deconstruction advocates that the source text has no absolute meaning and that faithfulness to the source text is impossible. Then arises the question whether translating is rewriting. According to the theory of family resemblance, translating and rewriting fall into the same category and the boundary between them is so fuzzy that they cannot be distinguished. Therefore, a translation cannot be simply measured by the term "faithfulness" or "unfaithfulness".


Elastic full waveform inversion of multichannel seismic data represents a data-driven form of analysis leading to direct quantification of the subsurface elastic parameters in the depth domain. Previous studies have focused on marine streamer data using acoustic or elastic inversion schemes for the inversion of P-wave data. In this paper, P- and S-wave velocities are inverted for using wide-angle multicomponent ocean-bottom cable (OBC) seismic data. Inversion is undertaken using a two-dimensional elastic algorithm operating in the time domain, which allows accurate modeling and inversion of the full elastic wavefield, including P- and mode-converted PS-waves and their respective amplitude variation with offset (AVO) responses. Results are presented from the application of this technique to an OBC seismic data set from the Alba Field, North Sea. After building an initial velocity model and extracting a seismic wavelet, the data are inverted instages. In the first stage, the intermediate wavelength P-wave v...


The Capital Budgeting Approach has been suggested as a method whereby the consumer may estimate the cost of his life insurance, by several authors. Many cost methods include parts of a formal capital budgeting model. But none to date has treated the purchase of life insurance as a pure capital budgeting decision. This article takes the consumer's viewpoint. Assumptions of lapse are not relevant to the consumer because he faces a lapse rate of one or zero in each year depending on whether he pays his premium. For life companies, lapse rates are vital to calculate an asset share accurately. The result of the Capital Budgeting Approach is a cost method that is more easily understood by both the consumer and the agent and that fairly reflects company decisions relative to high early cash values and dividends. The value of a life insurance policy to the consumer has been a difficult concept for years. This paper analyzes the life insurance policy as a series of cash and opportunity cash flows. Capital budgeting techniques are applied to the flows in the life insurance contract to reveal for insureds a comparative value of insurance in terms of rates of return and net present values. Requisites For Cost Method Any system of life insurance cost (value) comparisons should be simple. The primary method of dissemination of cost information to the public is through life insurance agents. Agents acquire information from trade sources. In order that accurate information may be transmitted, it must be simple to survive the round-about communication process from calculation to consumer. A second goal in a cost comparison system is to reflect the time value of money. From the consumer's viewpoint, a life insurance policy is a conPeter R.

SIS junction mixers were designed for SMA 400 - 520 GHz band, which is similar to ALMA band 8 (380 - 500 GHz). Two schemes were used to tune out the parasitic capacitance of the junction. When shunt inductors were employed, the input resistance is equal to R (close to R0), much higher than R/(omegaRC)2 when series inductors were used. This facilitates the impedance matching between the junction and the waveguide probe. Waveguide probe design was varied to achieve a low feed-point impedance to match the junction resistance. The optimal feed- point impedances for lower receiver noise temperature were also discussed.


Laricobius nigrinus (Coleoptera: Derodontidae) shows promise as a useful biological control agent for hemlock woolly adelgid, Adelges tsugae (Homoptera: Adelgidae). A field evaluation was conducted to assess the survival and reproduction of L. nigrinus under natural conditions and to quantify their impact on HWA populations. A predator exclusion study was conducted using 162 branches, each receiving one of three treatments: caged with predators, caged without predators, and uncaged branches. L. nigrinus adults survived from February to April, producing up to 41 progeny per female. Adelgid densities on branches exposed to L. nigrinus suffered a significantly higher rate of decrease than branches not exposed to predators. Current rearing of L. nigrinus is constrained by high mortality and a lack of knowledge as to which life stages incur significant mortality. A new rearing cage has been devised that enables the quantification of larvae reaching maturity, of pupal survival, and survival through aestivation. Our objective was to streamline rearing procedures by identifying life stages with high developmental mortality and to determine factors critical to the success of each life stage. Factors investigated were optimal larval density per cage and moisture level of soil in which adults aestivate. Density of individuals per cage did not significantly affect larval survival between 10 to 50 eggs per cage. Egg and larval stages suffered an average of 28% mortality at the egg densities tested. Survival through aestivation was significantly higher in the high and medium soil moisture levels than at the low moisture level. The L. nigrinus colony suffered approximately 30% mortality during pupation and approximately 60% during aestivation. Future research will focus on identifying other factors affecting L. nigrinus survival through aestivation. tsugae Field Rearing Procedures.


In modern theoretical physics, the laws of physics are directly represented with axioms (e.g., the Dirac–Von Neumann axioms, the Wightman axioms, Newton's laws of motion). Although in logic axioms are held to be true merely by definition, in physics the laws are entailed by laboratory measurements. This di ff erence is su ffi cient to warrant a more appropriate logical structure than axioms to represent the laws of physics. This paper first presents this logical structure and then demonstrates its supremacy. Specifically, an optimization problem on the entropy of all geometric measurements is introduced. Its solution is an optimized version of the Dirac–Von Neumann axioms that automatically restricts its observables to no more than the standard model group symmetry SU(3) and SU(2) x U(1) while simultaneously extending its probability measure to admit the Einstein Field equations as its equations of motion (i.e., it is a "gravitized" standard model). Remarkably, this result only holds in four-dimensions.


Objective: To investigate the structural abnormalities of the tempora-mandibular joint(TMJ) in patients with different maxillary and mandibular sagittal positions. Methods: 255 subjects were randomly selected from the orthodontic patients treated in the hospital in the past two years: 80 males and 175 females, and ages from 10 to 45 years old. Routine radiographs and MRIs were taken on both sides of TMJ with bite and open positions in order to evaluate the TMJ structures.The statistical analysis was conducted by using SPSS 17.0. Results: Among all the 255 patients, there were 89 skeletal Class I patients with 54 patients(60.67%) with abnormal TMJ structures, 96 skeletal Class II patients with 75 patients(78.13%) with abnormal TMJ structures, and 70 skeletal Class III patients with 47 patients(67.14%) with abnormal TMJ structures. Conclusion: TMJ structures abnormity is common in orthodontic patients, especially in skeletal Class II patients.


In identifying cinematic qualities—including Eisensteinian montage—in Faulkner's major fiction, scholars have conceived of film as an exclusively visual medium. This essay provides evidence of Faulkner's familiarity with Eisenstein's cinematic praxis by examining the similarities between the novelist's 1934 film treatment of Blaise Cendrars's Sutter's Gold and one that Eisenstein produced in 1930. It then argues that there is a striking continuity between the two treatments in the realm of sound—in particular, the imagining and inscription of film sound. Most surprising is the manner in which Faulkner's sonic experimentalism, clearly influenced by Eisenstein, works its way into the novel on which he was working at the time, Absalom, Absalom!. Informed by screen writing and film-sound technology, Faulkner's high-modernist novel contributes to emerging scholarly interest in the auditory culture of modernism.


The utility model provides a water-repellent elastic-cloth air-permeable sticker which comprises a waterproof agent layer, a base material layer, an adhesive layer and a release paper layer. The base material layer is made of elastic cloth. The water-repellent elastic-cloth air-permeable sticker is characterized in that the adhesive layer is a rubber hot-melting pressure-sensitive rubber layer, the adhesive layer is coated on the base material layer, an adhesive is in a shape of irregular gap, and the gap position without the adhesive serves as an air-permeable window. The water-repellent elastic-cloth air-permeable sticker has elasticity, can also have a waterproof performance and further has good using comfort.


Interlining of sleeve plays an important part in suit.The assembly part of interlining is sleeve flet pad,which is the skeleton of interlining of sleeve.Curvature of sleeve flet pad is the determinant factor of formative arts on sleeves. The experiment of different flet pad's curvature indicates that hardness of sleeve flet pad determines curvature of sleeve flet pad,and both elasticity and hardness determine formative arts on sleeves.


Conventional grinding is usually carried out in upgrinding mode, with the wheel moving in the opposite direction from the workpiece. In this paper, a thermal model is developed for upgrinding. This model is similar to our previous models of downgrinding in that the behavior of the workpiece, grains, fluid, and chips are all coupled. The model is used to compare the workpiece temperature rises in upgrinding and downgrinding, and to explore the effect of the location of heat generation. The model results are also compared with experimental data and are seen to yield reasonable agreement. Finally, the sensitivity of the results to some parameters which are not well known is explored.


We report on the application of femtosecond x-ray scattering to experimental studies of the photo-induced, structural phaser transition in VO2. The transition between the two crystalline phases of the material occurs, for sufficiently intense excitation, within 500 fs.


This paper proposes a method to obtain fronto-parallel (side-view) body part trajectories for a walk observed from an arbitrary view. The method is based on homography transformations computed for each gait half-cycle detected in the walk. Each homography maps the body part trajectories to a simulated side view of the walk. The proposed method is stable as the resulting normalized trajectories are not influenced by missing or omitted parts of the raw trajectories. Experiments confirm that normalized trajectories are in agreement with the ones that would be obtained from a side view.


AEA Technology has for many years used computer simulation for prediction and interpretation of the interaction of electromagnetic waves with charged particle flow. This paper focuses on one application area where computer modelling has been particularly successful in devising novel designs; namely, in the design of new variants of the high powered microwave tube known as the magnetically insulated transmission line oscillator (MILO). The MILO works by using a slow wave structure in the anode of the magnetically insulated line to generate microwaves by resonant coupling the wave field to the electron flow. The operating mechanising is similar to that of the magnetron, where electron kinetic and potential energy are fed to wave energy. The computer aided design process for the tapered MILO has been a four stage process: 1. initial design study; 2. validation, where direct comparison of PIC simulation and experimental results led to refinement of both experiment and simulation for an idealised validation configuration; 3. design optimisation using the validated software; and 4. experimental realisation of new designs. This paper surveys aspects of the work in each of these stages.
