Over 100 sediment cores were collected from US Virgin Island coastal marine and salt pond environments to document the record of sediment delivery to the coastal system on annual to millennial time scales, and the extent to which human activities have influenced sedimentation patterns. Cores were analyzed for sedimentology, geochronology (210Pb, 137Cs, 7Be and 14C), and high-resolution elemental composition (scanning x-ray fluorescence (XRF) and laser ablation inductively coupled mass spectrometry (LA–ICP–MS)). The centennial–millennial record reveals the natural transition from terrestrial to marine ~6–4 kya in response to the Holocene sea-level rise. Coastal salt pond cores record initial pond development as coral growth between island headlands cut off and isolated existing marine embayments ~2 kya. The decadal–centennial record is dominated by human activities, primarily road construction, manifested as a ~10× increase in sediment accumulation rate where development is heavy, a ~2.5× increase where development is moderate, and no detectable increase in undeveloped areas. Annual millimeter- to centimeter-scale laminae in salt pond cores represent individual depositional 'events'. Light-colored, Ca- and Sr-rich sands represent marine overwash deposits that in some cases can be tied to tropical cyclones. Dark-colored Al-, Fe-, Ti-, Si-rich sandy muds represent island runoff when rainfall rates exceed a threshold of ~1.2 cm/day. Organic-rich layers represent microbial mat growth between depositional 'events'. Marine overwash and rainfall/runoff layers fluctuate on an annual–decadal scale during the historical period, but show much more variability over the previous ~1400 years, suggesting sediment source(s), depositional processes, and/or driving mechanisms have not remained constant during at least the late Holocene.


Knowledge concerning rotation of permanent teeth is based primarily on posteruptive disturbances. Habitual, mechanical, local, or environmental factors have been cited as etiologic agents. The deviated path of eruption of the permanent incisors, subsequent to traumatic injury or pathologic change, is designated as a pre-eruptive disturbance. 2 Thus the rotation of permanent teeth can be divided into two categories in relation to etiologic factors: (1) rotation of permanent teeth caused by posteruptive disturbances and (2) those caused by pre-eruptive disturbances. If these pre-eruptive disturbances are significant in altering the eruptive path of the permanent incisors, it is possible that similar conditions may influence the eruption of the permanent posterior teeth. There are several adverse factors operative in the pre-eruptive phase of permanent tooth emergence, for example, (1) asymmetrical root resorption of deciduous molars, (2) pathologic involvement of deciduous roots, and (3) the early loss of the first permanent molar prior to the eruption of the adjacent premolars. Logically, these conditions can be differentiated into separate entities as they affect tooth eruption. According to Morgan's study,3 it was evident that if a deciduous tooth was retained beyond normal exfoliation time, the succeeding permanent tooth had a tendency to rotate. One reason for this prolonged retention was given as the incomplete resorption of deciduous roots. Another was the lack of co-ordination between the resorption process of deciduous tooth roots and the eruption process of the permanent successors. Morgan's emphasis was focused on prolonged retention as the factor responsible for rotation of the permanent successor. Ash2 stated that overretention of a mandibular second deciduous molar may result in a generalized malocclusion. He demonstrated that a minor irregularity of the dentition may cause a generalized dental irregularity. Malocclusions that occur from this type of minor irregularity are common. The axial inclination of teeth must be considered when occlusion is appraised. The importance of this has been expressed by many workers in evaluating dentofacial balance and harmony.4 7 These studies were based on axial inclination of anterior teeth, which undoubtedly do influence the profile of the face. However, the axial inclination 'of posterior teeth has not been fully investigated. It was shown by Marshall-Day8 and Salzmann9' 10 that the loss of a permanent molar or molars created abnormal drifting


GROUP LEADERSHIP. By Robert D. Leigh. New York: W. W. Norton & Co., I936. Pp. 259. $2.50. President Leigh, of Bennington College, has here undertaken a task which unnumbered persons have thought ought to be done. How well he has done it is a question which can probably be answered only by the number of people who think he has done it well. He has undertaken to make rules of order for functional groups actually grow, as they are always said to grow, out of the convenience of the groups themselves. It is clear to anyone who tries to remember them all that rules built upon parliamentary procedure only loosely, even if arduously, fit parlor discussions of what is to be done. The misfit is not total but it is quite trying to the amateur. Leigh seeks to keep from Robert's Rules of Order and similar manuals what does fit, and to change either the name or the procedure of what does not fit smaller and less formalized discussion groups. The tendency to substitute a small cabinet for the large city council, a unicameral body for the prevailing legislature, and to increase the ever present committee work without end indicates a political field ripe for some reasonable reform of deliberative procedure. Prefacing his discussion of practical rules for large meetings with the technique of individual thinking and the process of thinking out loud in small discussion groups or committees, the author sets down simply what such scholars as Dewey, Wallas, Dimnet, Lippmann, Lindeman, Follet, Walser, Elliott, Sheffield, and others have taught us about fecund thinking, individually or collectively. Then follows an account more humanized and interesting than most people would think.possible of the conduct of business by formal bodies, with closing chapters on "special action for special purposes" and the general problem of organizing bodies for discussion and deliberation. An Appendix summarizes modern rules for procedure as a clear and practical substitute for the inherited parliamentary rules. An annotated Bibliography closes the volume. It is a needed job neatly done. Fortunate the faculty with a president so sensitive to the need for, the difficulty of, and the fruition from interpersonal thinking! T. V. S.


Efficient protocols, developed for micropropagation of pineapple (Ananas comosus L) var. Queen through in vitro culture of axillary buds from crowns of mature fruits, slips and suckers (induced from adult plants), are presented in this paper. Axenic buds, initially cultured on MS medium with high auxin: cytokinin ratio, when shifted onto MS with high cytokinin: auxin, showed high percentage of culture establishment (80.6%). Further, the shoot multiplication increased upon subculture on freshly prepared high BAP containing multiplication medium. The cycle was found to be repeatable. MS with 2.5 mg L-1 BAP, 2.0 mg L-1 NAA & IBA, 10% CW (coconut water) was found to be the best multiplication medium. In vitro grown shootlets were successfully rooted on MS with 0.5 mg L-1 NAA and 0.5 mg L-1 IBA. While evaluating different culture systems viz., semi-solid, liquid stationary and liquid shaken, the last one was found to be the most promising and maximum buds could be produced over a period of 6 months. Maximum (12.25±1.20) buds per culture in liquid shaken culture was observed in the fifth passage (each of 30 d duration) in an experiment of 6 months duration. The requirement of BAP in liquid shaken culture medium was almost half of the requirement in semi-solid medium to achieve a maximum multiplication. Pulsing of explants from liquid culture to semi-solid medium enhanced the culture response as evident from higher shoot multiplication rate with all types of explants. The potential of callus cultures in regenerating plantlets was found to be immense. Maximum (14.33±2.78) plantlets per culture were developed through this technique. They performed at par with in vitro grown shootlets developed from axillary buds. This offers a route to integrate callus based plantlet development with in vitro multiplication to produce more plantlets within a short time, though the risk of somaclonal variation remains, which is sought to be minimized through judicious cultural manipulation.


Bangladesh has a subtropical monsoon climate characterized by wide seasonal variations in rainfall, moderately warm temperatures, and high humidity. Bangladesh lies in the North-Eastern part of South Asia between 20.02° and 26.038° north latitude and 88.001° and 92.041° east longitude. The goats of Bangladesh usually show estrus across the year with no anovulatory period. Bangladesh has the second highest population of goat among the Asiatic countries which accounts for about 60.60 million heads representing 57% of total ruminant livestock (Faostat et al., 2009). The intensive goat production and the wide spread application of the controlled breeding techniques, such as artificial insemination increased the need for an accurate early pregnancy diagnosis. The pregnancy diagnosis in goats is essential for better efficacy and management of reproduction (Doize et al., 1997), providing information about conception rates after artificial insemination (Matsas et al., 2007), gestation course (Ameret al., 2010), time for drying-off and parturition date (Doize et al., 1997; González et al., 2004). The utilization of an accurate and easily applicable method for pregnancy diagnosis allows the timely repeated insemination, breeding or culling of non-pregnant animals (Ameret al., 2010). A number of techniques for pregnancy diagnosis have been Pregnancy diagnosis in goat by using vaginal cytology and trans-abdominal ultrasonography


In the compass of partition literature depiction of violence and its consequent trauma has been at the centre/ heart and in such delineation of violence – both physical and psychological- there is the unmistakable presence of a sense of being lost in a world of incommunicable experience on the part of the victims/ protagonist. The violence and the consequent trauma they experienced was a life-changing one and the haunting incident corroded them within. Often such nightmarish experiences seize their volition and sensibility to such an extent that they lose their sanity and equilibrium and become altogether different entity. People of all walks of life were its victims; however, needless to say that the worst and most ill-fated were the women on either side of the border. At the same time, on the other hand there are occasions, though rare, when the perpetrator of the violence himself has become the victim- a prey to his own bestiality and inhuman barbarity. In this paper my objective is to present this duality with reference to two short stories of Sadat Hassan Manto – 'Open It' and 'Cold Meat' and to light on the presentation of violence that overtly unlocks the gruesome exercise of atrocity and inhumanity.


Abstract : NF1-assocaited MPNST accounts for 50% of all MPNSTs and is one of the most difficult subtypes of soft tissue sarcoma to manage, given its poor sensitivity to conventional systemic therapy and radiotherapy and high likelihood to metastasize. Novel therapeutic development is imperative. Using comprehensive and integrative genomic approaches, we have identified recurrent inactivating genetic alterations of three central pathways: PRC2 (80%) core components (EED or SUZ12), CDKN2A (81%) and NF1 (72% of non-NF1-associated) in all MPNSTs, and the three components significantly co-occur, suggesting their critical and cooperative roles in MPNST pathogenesis. We demonstrated that MPNSTs with complete PRC2 loss showed complete loss of H3K27me3 and aberrant transcriptional activation of multiple PRC2-transcriptional targets. Here, we have further validated the high sensitivity and specificity of using H3K27me3 as a diagnostic biomarker for high-grade MPNST. The evaluation of using H3K27me3 as a prognostic biomarker in MPNST is ongoing. Therapeutically, we have found that the combination of MEK inhibitor and CDK4 inhibitor resulted in at least additive effects of growth suppression of human MPNST cell lines in vitro; We are currently evaluating newer generations of epigenetic therapeutics in PRC2-loss MPNST cells. These studies will be extended to in vivo xenograft studies and relevant genetically engineered MPNST mouse models.


Clinker free calcium oxide (f-CaO) content is an important indicator of cement quality. Considering the production characteristics (strong coupling, time-varying delay) in the cement process industry, a soft sensor model was developed by combining various methods. First, a new decoupling method is proposed to deal with the strong coupling between variables, which achieves data decoupling between process variables through the attention mechanism and the long short-term memory network. Second, a novel time-series matching technique is proposed to handle the time-varying delays, which utilizes a window selection mechanism to adaptively select the time period in which each process variable influences the target variable. Third, the critical features of the variables are extracted by a one-dimensional convolution network (1D-CNN). Last, a combination of the data decoupling method, window selection mechanism, and 1D-CNN is applied to develop a soft sensor model (ADM-WGM-CNN), which implements the measurement of f-CaO content. The experimental results demonstrate that the ADM-WGM-CNN model has better measurement performance.


We consider tackling a single-agent RL problem by distributing it to $n$ learners. These learners, called advisors, endeavour to solve the problem from a different focus. Their advice, taking the form of action values, is then communicated to an aggregator, which is in control of the system. We show that the local planning method for the advisors is critical and that none of the ones found in the literature is flawless: the egocentric planning overestimates values of states where the other advisors disagree, and the agnostic planning is inefficient around danger zones. We introduce a novel approach called empathic and discuss its theoretical aspects. We empirically examine and validate our theoretical findings on a fruit collection task.


The carcinogenetic impact of risk factors on esophageal cancer (EC) may differ according to the portion of the esophagus where the tumor occurs. It is unclear why more esophageal squamous cell carcinomas (SCC) developed in the middle location. We carried out a multicenter case–control study in Taiwan to assess anatomical subsite risk discrepancy for this neoplasm in regard to the consumption of alcohol, tobacco and betel quid. Four hundred forty seven incident patients with pathology‐proven SCC of the esophagus (107 were upper‐third [U/3‐EC], 199 middle‐third [M/3‐EC] and 141 lower‐third [L/3‐EC] cases), as well as 1,022 gender, age and study hospital matched controls were analyzed by unordered polytomous logistic regression. All consumption of the three substances was related to the development of each subsite of EC, with a heterogeneously higher risk for current smokers (adjusted odds ratio (AOR) = 6.2) found in M/3‐EC and for current chewers, in U/3‐EC (AOR = 4.9). The joint risk of contracting lower two‐third EC for drinking and smoking appeared to significantly surpass those estimated by a multiplicative interaction model. Concomitant exposure to these two agents brought the risks of EC at all three subsites up to 10‐ to 23.9‐fold and additional tobacco‐free betel quid to a 30.3‐ to 75.0‐fold. In conclusion, tumor subsite discrepancy risk is related to prolonged exposure to tobacco and betel quid with inflorescence. Alcohol interacts with tobacco in a stronger supra‐multiplicative way in the middle portion of the esophagus, probably explaining why esophageal SCC occurs more commonly at this anatomical location. © 2007 Wiley‐Liss, Inc.


OBJECTIVE
To estimate prevalence of malnutrition on admission to hospital and the relationship between nutritional status and prognosis.

METHODS
Four thousand and twelve patients admitted to general surgery department were evaluated by a lot of nutrition indexes within 48 h. Operative morbidity and complications were recorded to identify the difference between malnourished and well-nourished patients.

RESULTS
Malnutrition rate of all patients according to BMI, TSF, MAC, AMC, albumin, prealbumin, and lymphocyte count was 21.3%, 50.6%, 20.5%, 21.2%, 24.2%, 35.4% and 55.8%, respectively. The prevalence of malnutrition as defined by SGA and MNA were 38.8% and 20.8%. The older patients (> 60 years old) were associated with a higher prevalence of malnutrition (47.6%) compared with those younger than 60 (31.5%). Malnutrition was more frequently occurred in cancer patients than non-oncologic patients (64.5% vs 22.4%). Patients with digestive tract disease had higher rates of malnutrition than those without digestive tract disease (52.6% vs 30.0%). There were large differences in the morbidity and complications between well nourished patients and malnourished patients (4.0% vs 1.1%, P < 0.01 for morbidity; 19.8% vs 5.9% for complications).

CONCLUSIONS
The prevalence of malnutrition in hospitalized surgical patients is high. Malnutrition was associated with increased length of stay, higher operative morbidity and complications.


Recently, two-stage three-machine assembly flow shop issues have drawn a lot of researchers' attention. However, the learning idea has not been widely introduced into two-stage assembly flow shop model. In view of this observation, authors then study a two-stage threemachine flow shop scheduling problem with learning consideration in which the goal is to minimize the total completion time of given n jobs. For saving time cost, authors proposed six types of particle swam optimization methods for searching approximate solutions compared to the lower bound for the small number of jobs and big numbers of jobs, respectively. Several statistical tools involving analysis of variance (ANOVA) and Fisher's least significant difference tests are utilized to determine the proposed six PSOs for three data types in term of the average gap.


Fourier transform infrared spectroscopy was used to study the interactions among LiCl, ZnCl2, and AlCl3 with N,N-dimethylformamide (DMF) and poly(acrylonitrile) (PAN). It was observed that all three salts complex with DMF as well as PAN. The strength of the cation interaction with the >CO oxygen of DMF was found to be higher than that with the CN group of PAN. The >CO stretching frequency of DMF with ZnCl2 was red shifted, indicating stronger complex formation compared with other two cations. With the addition of salt, the salt–DMF pseudo solvent was found to become a θ solvent for PAN compared with neat DMF. This change in PAN solvation power was primarily the result of DMF–salt complexation. As a result of the complexation, Mark-Houwink constant a, was found to reduce from 0.75 (for pure DMF) to ∼0.6 for DMF–salt solvents, indicating decreased PAN chain expansion. Comparison of intrinsic viscosity [η] values indicated that addition of salts to PAN–DMF solutions resulted in: (i) decrease in the DMF solvation power, which causes less expanded polymer coils, and (ii) increased interpolymer chain entanglements via salt-promoted chain association. © 2005 Wiley Periodicals, Inc.

This survey is aimed at identifying the satisfaction levels in terms of the mentorship programs in the organization. Perceived organizational support partly mediated the relationship between specific types of mentoring support and job satisfaction and affective organizational commitment. A mentorship program enables employee to make a smoother transition into the workforce, furthers his/her development as a professional, gains the capacity to translate values and strategies into productive actions, complements ongoing formal study , training and development activities, enables career development opportunities. It also encourages new and different perspectives and demonstrates strengths and explores potential. Listed below are some reasons why agencies choose to establish mentoring programs. As part of the Onboarding process -- mentoring helps new recruits, trainees or graduates settle into the organization; Skills Enhancement -- mentoring enables experienced, highly competent staff to pass their expertise on to others who need to acquire specified skills; Professional Identity -- when younger employees are early in their careers, they need help understanding what it means to be a professional in their working environment. Professionals embody the values of the profession and are self-initiating and self-regulating. Mentors play a key role in defining professional behavior for new employees. This is most important when employees first enter the federal workforce; Career Development -- mentoring helps employees plan, develop, and manage their careers. It also helps them become more resilient in times of change, more self-reliant in their careers and more responsible as self-directed learners; Leadership and Management Development -- mentoring encourages the development of leadership competencies. These competencies are often more easily gained through example, guided practice or experience than by education and training; Education Support -- mentoring helps bridge the gap between theory and practice. Formal education and training is complemented by the knowledge and hands-on experience of a competent practitioner; Organizational Development and Culture Change -- mentoring can help communicate the values, vision and mission of the organization; a one-to-one relationship can help employees understand the organizational culture and make any necessary changes; Customer Service -- mentoring assists in modeling desired behaviors, encouraging the development of competencies in support of customer service, and above all, cultivating the right attitudes; Staff retention -- mentoring provides an encouraging environment through ongoing interactions, coaching, teaching, and role modeling that facilitates progression within the organization; mentoring has been found to influence employee retention because it helps establish an organisational culture.


As the second of two commemorative poems marking Elizabeth Drury's untimely death, John Donne's The Second Anniversarie revisits the theme of mortality from a perspective that is more private and introspective than that of its predecessor. While The First Anniversarie addresses its reading audience as it catalogues evidence of decay throughout the physical universe, the second poem features an interior conversation between the speaker and his soul regarding the mysteries of the soul's hidden aptitudes and its afterlife.1 The technique of inner colloquy as a means to disclose the soul's nature is fundamentally Augustinian in origin, being most evident in his early dialogues, but also implicitly shaping his discussions of selfknowledge.2 Augustine uses the framework of inner dialogue to focus his mental attention on the interior self and thereby disclose interior truths hidden within the soul's cognitive capacities. The Second Anniversarie, designed to trace the Progres of the Soule, draws upon Augustinian techniques of introspective scrutiny to craft its spiritual itinerary, as Louis Martz, Edward Tayler, and others have demonstrated.3 However, what remains less recognized is the poem's complex renegotiation of that tradition, as it both engages and resists techniques of Augustinian interiority. The Second Anniversarie represents the psychological perspective of an inconstant, conflicted speaker, whose persistent attachment to the world's follies and curiosities undermines his attempts to gain the very spiritual knowledge that he professes to desire. Alternating between moments of interior presence and external distraction, the poem charts a digressive and vexed progress, as Donne's speaker remains simultaneously enticed by terrestrial and transcendent ambitions, a state of mind pertinent to the poet himself.1. Augustinian Foundations: Interior Dialogue as a Basis for Epistemic Certainty and Spiritual UnderstandingIn order to understand The Second Anniversarie's unusual engagement with Augustinian dialectic, it will be helpful first to consider Augustine's own use of the dialogue form and to recognize its importance for his philosophy and spirituality. Early in his career (386-96), Augustine composed a collection of literary-philosophical dialogues, which he described as mental conversations taking place between himself and his reason. Through a scripted sequence of questions and responses, the dialogue's literary personae discuss a range of philosophical concerns, including the soul's relation to the body, its immortality, and its capacity for self-understanding.4 Even after abandoning the dialogue's literary form, Augustine continued to write dialectically, advancing his philosophical argument through a sequence of questions (see Confessiones 10; De Trinitate 10-15). One of the assumptions underpinning the dialogue form is the notion of anamnesis or recollection: a Platonic belief that the soul once enjoyed complete understanding in its heavenly pre-existence before it descended into its life in the body (see Meno 81 c2-d4). Consequently, the process of learning represents the recollection of forgotten knowledge from within oneself and not the acquisition of evidence from without.5 The dialectical process serves to excavate and disclose answers that were latent and previously unrecognized within one's own mental capacities.6The notion of anamnesis held a powerful appeal for Augustine, since it reinforced both his belief in the capacious powers of memory and his suspicion of sense experience. While granting that knowledge of temporal particulars is useful and necessary for lived experience, Augustine considered such sense-based knowledge to be less significant than the interior truth discovered from within the soul.7 Hence, in his early dialogue Soliloquies, Augustine's Reason advises him to develop the spiritual eye of the mind, which has the capacity to perceive interior truth. The power of inner perception is strengthened by distancing oneself, both physically and psychologically, from the world's distractions. …


Epidemiological studies suggested that the prevalence and the disease severity of non-alcoholic fatty liver disease (NAFLD) are lower for people who drink modest amounts of alcohol than those who are abstainers. Nevertheless, the evidence is still inconclusive because some recently published studies1 showed that modest alcohol consumption (MAC) increases hepatic fat without increasing the risk of advanced fibrosis.

Remarkably, we found in our population that MAC has a beneficial effect in preventing not only NAFLD but the main features of the metabolic syndrome, including body mass index (BMI), blood pressure, homeostatic model assessment-insulin resistance and C-reactive protein levels. Accordingly, NAFLD and non-alcoholic steatohepatitis (NASH) prevalence, liver enzymes and inflammatory markers were lower in subjects who took modest amounts of alcohol than those who are abstainers (table 1).

Hence, we propose to take advantage of meta-analysis to estimate from published data …


The new administrative computing is quite different from its predecessors. It involves different people, who are often engaged in qualitatively different tasks. And it recognizes that one type of computer does not offer a complete solution to the administrative and academic computing needs on college campuses. The changes in administrative computing–those of the past decade and those coming in the next ten years–represent challenging, dynamic, and exciting opportunities for campus administrators interested in harnessing the new technologies for institutional advancement and their own professional development.


In 2000, the first work of fiction by Atiq Rahimi, Terre et cendres was published; in 2011, Maudit soit Dostoievski. In the first stage, the wandering of an old man and his grandson for Afghan lands devastated by the war against the Soviets; in the second, another wandering, that of a young Afghan man by a Kabul immersed in civil war after the withdrawal of Soviet troops. The objective here is to enunciate some notes on a dry, rough, stripped writing, which is made visual along with the displacement of subjects immersed in the horrors of wars.


Gold prisms with edge length ranges from nanometer to micrometer scale were prepared in large quantities through facile liquid-liquid interfacial reaction and solution-phase reactions. The technological keys to synthesis of gold microprisms are (i) selecting poly(N-vinylpyrrolidone) (PVP) as the shape-directing agent to induce the preferential growth of nanoprism seeds and (ii) using weak reducing agents to lower the reduction rate of gold ions so that gold ions were reduced slowly onto the surface of the growing nanoprisms. Thus, the reduction of ions in the presence of PVP by some weak reducing agents generated a large number of gold microprisms (as defined by edge length of prisms). On the contrary, the relatively fast reduction of ions could only lead to formation of spherical gold particles.


For protection of the LVDC distribution systems, the overcurrentbased protection is the first choice and the differential protection is the last choice. The differential protection needs the synchronizing and comparing functions. Implementing these functions for the LVDC system with high fault transients is difficult and expensive. Also, the differential protection does not provide the backup protection. On the other hand, it does not have complexities of the over-current protection like coordination and setting issues. This paper proposes an over-current protection scheme that is based on the use of the over-current relays for the protection of a radial LVDC system with PV units. The protection system must respond toboth utility grid and microgrid faults which isolates the smallest possible section of the radial feeder to eliminate the fault.

Competent authorities and international organisations introduced the core definitions. Banking regulation is adapting to the New reality through RegTech.


Wake Forest's Physics of Music is an introductory science class focused on musical acoustics. It is commonly taken by music students or non-science majors seeking a science credit. The course has been taught using three different texts (Rossing et. al., Heller, and Berg and Stork) in the past few years. The texts vary in approach, focus, and breadth. I will describe some successes and difficulties I have experienced while teaching from these texts. I will also comment on additional texts such as Hall and Campbell & Greated which I regularly use to supplement the others.Wake Forest's Physics of Music is an introductory science class focused on musical acoustics.

As an art form in which people express their thoughts and emotions effectively, music is not only closely connected with real life, but also a reflection of people's values and artistic cultivation. Teacher-student concerts can not only ensure the high-quality development of teaching activities, but also the new education model is easier to mobilize students' enthusiasm for classroom knowledge learning than traditional teaching methods. Therefore, this article starts from different levels and analyzes how to find a better way to innovate the form of teacher-student concerts, hoping to ensure a better rise in student learning quality.

Online multiplayer games are becoming massively popular nowadays. However, the churn of the players is becoming a significant concern as it is challenging to predict whether a player will churn or not, impacting business revenue. In this research, authors tried to solve this problem by predicting the player churn in advance using predictive analytics, thereby enabling the business owners to undertake steps to prevent player churn resulting in revenue stability. To achieve this, the authors collected the data from online and gaming platforms and then applied various pre-processing steps such as data conversion to make data suitable to use and then tested and applied a machine learning-based model for prediction by selecting churn period as the threshold value. Finally, various classifiers, such as logistic regression, were applied to predict whether a player will churn. The results were very satisfactory, as predicting churn with perfect accuracy was possible. The decision tree provides the best results, which were proximately 99.1 %, and other algorithms like logistic regression, random forest, and Adaboost gave predictive results of 96.86 %, 95.47 %, and 98.8 %, respectively. The accuracy of all the models has also been summarised. Hence, by making predictions in advance, the online platforms will take preventive measures to minimize the churn of players and increase revenue accordingly.


The research deals with the problem of identification and substantiation of mechanisms of social capital influence on individual innovativeness of employees, which increases the positive innovation effect in companies. The study proposes a new methodological approach and technology for assessing the social capital of employees, taking into account the factors of interpersonal and institutional trust, involvement in social networks, social norms, and its impact on the employee's innovativeness. The methodology uses methods of system analysis and synthesis, expert assessments, statistical modeling, and survey. Numerical experiments are carried out using collected data from special surveys of employees of a machine-building company. An assessment of social capital and its impact on the employee's innovativeness is determined and a statistically significant influence of the factors of "trust" and "social networks and connections" on social capital is set. It is revealed that the main determinant of innovativeness is the risk appetite. It is proved that the innovativeness model includes factors of "trust" and "social networks and connections". The cumulative effect of social capital on innovativeness is positive and statistically significant.


This study was conducted to determine the efficacy and safety of irinotecan (CPT‐11) as second‐line therapy in patients with advanced cervical carcinoma.


Abstract Background: Success of any medical treatment depends on understanding the true origin of symptom development—this is also naturally true of acupuncture. All therapeutic actions must consist of not only relieving patients' pain but also reinstating the correct working order of the body's defense mechanisms and of the organ whose weakness caused the ailment to develop. Early diagnosis of an internal weakness, which could potentially lead to development of a pathological syndrome—even before any symptom is detected—could be the basis of effective prevention. The aim of Auricular Causative Diagnosis (ACD) is to discover the inner causes of pathologic conditions. ACD is based on visualization and analysis of the pathologic marks in Auricular Points (APs). ACD allows physicians to identify existing illnesses precisely and determine which inner organ is fragile and therefore responsible for the development of a symptom. ACD can even be used to anticipate and reveal developing pathologic processes before...

Aim To investigate the effect of inhibiting NF-κB activity on the mRNA expression of TGF-β1 in the diabetic kidneys. Methods The male Wistar rats were divided into: the group A was the normal rats, the group B was the diabetic rats without any treatment, and the group C was the diabetic rats treated with PDTC (an inhibitor of NF-κB activity). The diabetic model was made by the intraperitoneal injection of streptozotocin. After a period of 18 weeks, the kidneys were taken out from all the rats to examine the NF-κB activity by EMSA and the mRNA expression of TGF-β1 by RT-PCR, as well as to observe the glomerular basement membrane (GBM) thickening and mesangial matrix (MM) density(MM area/mesangial area) by electron microscope. Also the 24 h of urine albumin excretion (UAE) was measured. Results The renal NF-κB activity in group B (1.85± 0.54×10 6) was significantly higher than that in the group A (0.07±0.11×10 6, P0.01), and in the group C (0.25±0.25×10 6) lower than in the group B(P0.01). Compared with those in the group A,the UAE (2.18±1.98 mg vs 0.41±0.47 mg, P0.01) ,the GBM thickening (531.6±107.6 nm vs 312.4±25.4 nm, P0.01) and the MM density (56.41±6.78 vs 33.95±5.22, P0.01) were increased significantly in the group B,and all the UAE (0.56 ±0.72 mg),the GBM thickening (315.8±21.4 nm) and the MM density (37.97±7.37) in the group C lower significantly than those in the group B(all were P0.01). The mRNA expression of TGF-β1 in group B(0.53±0.20)was increased significantly when compared with those in the group A(0.26±0.13,P0.01)and in the group C(0.29±0.10,P0.01).Conclusion Inhibiting NF-κB activity can delay the DN and decrease the mRNA expression of TGF-β1 in diabetic kidneys, suggesting that NF-κB may join in the pathogenesis of DN by way of TGF-β1.


A fundamental paradigm shift to patient-centric health services is needed to meet the challenges such as increasing healthcare costs, ageing population, and unhealthy lifestyles. Designing patient-centric services is challenging because of medicaland health data heterogeneity and lack of standardization for Personal Health Records (PHR). Further, designing patient-centric systems, especially in healthcare is a challenge as they are influenced by emotions when users are influenced by emotions triggered by privacy issues. In this study, we focus on the engineering method to design a patient-centric system that considers medicaldata heterogeneity and emotional security issues. We plan to develop a methodology for designing a patient-centric system with a multi-agent system (MAS) approach where agents operate with smart contracts. An emotional security framework is integrated into the design of such systems. Multi-faceted validation and verification are used to evaluate the engineered method. A framework for Evaluation in Design Science Research (FEDS) is used to define the evaluation activities and tools.


Reactive dyes of the Procion type* offer a versatile dyeing system for producing dyeings of attractive colour and good fastness to washing. A merit of the Procion system is that, since it is based on a simple chemical reaction with the fibre, it is capable of variation in easily controlled and readily understood ways common to many chemical reactions. The rate of the fixation reaction can be made to vary from slow at room temperature and mild alkalinity to rapid at high temperature or high alkalinity, intermediate rates being achievable at will by controlling various simple factors. Choice of method of dyeing is therefore wide and will depend largely on the particular equipment readily available.


Where genetically unrelated members of a group benefit from mutual adherence to a social norm, agents may obey the norm and punish its violators, even when this behavior cannot be justified in terms of self-regarding, outcome-oriented preferences. We call this strong reciprocity. We distinguish this from weak reciprocity, namely reciprocal altruism, tit-for-tat, exchange under complete contracting, and other forms of mutually beneficial cooperation that can be accounted for in terms of self-regarding outcome-oriented preferences. We review compelling evidence for the existence and importance of strong reciprocity in human society. However, where benefits and costs are measured in fitness terms and where the relevant behaviors are governed by genetic inheritance subject to natural selection, it is generally thought that, as a form of altruism, strong reciprocity cannot invade a population of non-reciprocators, nor can it be sustained in a stable population equilibrium. We show that this is not the case, and offer an evolutionary explanation of the phenomenon. As the late Pleistocene is the only period long enough to account for a significant development in modern human gene distributions, we base our model on the structure of interaction among members of the small hunter-gatherer bands that constituted most of the history of Homo sapiens, as revealed by historical and anthropological evidence.


c-axig highly oriented crystallite films of AIN have been prepared on Si substrates by d. c. planar magnetron sputtering. The analysis for the infrared absorption spectrum indicated the frequencies of crygtal lattice longitudinal and transverse vibration modes being ag 2.5×1013Hz and 1.8×1013Hz. The optical phonons at 297, 512, 607, 656, 832cm-1 have been observed in Eaman spectrum of AIN thin filmg. The modes of these phonong were determined by comparision with those of the given binary compounds crysbalized in wurtzite structure. Further analysis shows that AIN is a crystal with which interaction forces were mostly electrostatic in original and the highest frequency of the phonons was directly
proportional to r-3/2M/1/2.


In his excellent article Professor Khan raises concerns regarding the awarding of Membership of the College without adequate checks. He points towards the College's high standing and its ability to guide opinion in countries which have not yet developed such structures for themselves. The British


ical, and economic aspects of a changing society as a whole, to present that society's strengths and weaknesses, and to identify the patterns of behavior characteristic of its members." No significant aspect of contemporary Egyptian society has been neglected. The analyses and interpretations may be brief—understandably so in view of the scope of the subject and the size of the book— but they are competently done. The absence of documentation is offset by a good bibliography. A proper index would be more helpful than the "Index of Topics" that merely spells out the contents of each chapter. More objectionable is the price, which seems exorbitant for a multilithed book of moderate length. Surely $8.00 entitles the reader to maps that are more informative and less tantalizing.


Neonicotinoid pesticides have been blamed for declines in bee populations worldwide. The chemicals don't kill bees, instead neonicotinoids impair the insects' abilities to learn, navigate, forage for nectar, and reproduce, according to studies published over the past several years. Now, researchers report that bees exposed to the pesticides also become less effective pollinators for crops (Nature 2015, DOI: 10.1038/nature16167). The study is the first to demonstrate that neonicotinoids can decrease the quality of a food crop by affecting bee pollination, says Maj Rundlof of Lund University, who was not involved in the work. "This is a strong indication that farmers, particularly those growing insect-pollinated crops, should consider both the gains and the costs of pesticide use when selecting a pest management strategy." About 30% of our food comes from crops, including fruits, nuts, seeds, and oils, that depend on insect pollinators, according to Dara A. Stanley of Royal Holloway, University ...


We have met here this afternoon to commemorate the life and work of a great pioneer of modern anaesthesia, 'Frederic William Hewitt' who was born in 1857 and who died in 1916. A recent lecturer in this hall began with the remark that Thomas Clover had attended the best medical school in London. I cannot say the same of Hewitt as I have failed to find any record that he ever came to Bart's but he managed to overcome this initial handicap in a remarkable way. I will try to give you an impression of conditions forty years ago and to show how anasthetic techniques were influenced by Hewitt. I will then indicate very briefly the changes which have occurred since those far-off days and will endeavour to assess our net gains and losses. I have considered carefully what angle of approach to this subject was the right one and this led me to think of what is the most important aspect of our speciality. All kinds of factors might be cited such as the comfort of the patient or the provision of ideal operating conditions for the surgeon, but none of these compares with sufety. No one can read Hewitt's writings without being impressed by the paramount importance which he attached to safety. For example in 1912 he studied statistics relating to over one million anasthetics and calculated that the death rate with ether was 1 in 16,302 and with chloroform 1 in 3,162, figures which would be regarded as remarkably low at the present time. The founders of the Association of Anasthetists of Great Britain and Ireland followed in his steps when they chose for their motto In somno securitas. I will therefore take 'safety' as the theme of my somewhat random observations. I fear that some of my remarks may appear to be unduly biased or egotistical. I apologise if this is so, but I can only record what I have

We were interested in the discussion about whether "therapy magnets" can have therapeutic effects on humans. Although we do not want to enter the debate about whether the application of a modest static magnetic field (SMF) can lead to "pain relief", we would like to point out some scientific facts to help shed light on the discussion. Indeed, recent experiments show that the case against such magnets having any effect on humans is by no means closed, as Robert Park suggests in his letter (January p16).


Submitted for the DFD19 Meeting of The American Physical Society A Hybrid Low-order Model of Dynamic Lift Response to Time-varying Actuation1 XUANHONG AN2, Princeton University, DAVID WILLAMS3, Illinois Institute of Technology — Time-varying actuation from a synthetic jet actuator has previously been shown to be an effective way of controlling unsteady flow separation. In order to integrate this type of actuation into a real-time control system, a low-order model of the lift response to the actuation is desired. The current work proposes a low-order approach to modeling the lift response to time-varying leading edge actuation on a stalled airfoil. Dynamic Mode Decomposition (DMD) is employed to extract from the flowfield the critical dynamical information, which is connected to the lift variation. It is shown that there are two sets of DMD modes associated with two different frequencies. These two frequencies are contained in both the actuation signal and the lift response. Based on the information provided by the critical DMD modes, we propose a hybrid low-order model which consists of a time delay decay model and a convolution integral model. This hybrid model is capable of accurately predicting the lift response of an airfoil to the time-varying actuation. 1The support of AFOSR under Grant FA9550-18-1-0440 Numbers and ONR under Grant Number 00014-14-1-0533 is gratefully acknowledged. 2Postdoctoral Research Associate 3Professor Xuanhong An Princeton University Date submitted: 01 Aug 2019 Electronic form version 1.4


The measurement of affordability is important to understanding who has housing affordability issues; the spatial variation of these issues; and the extent of the problem in the community. This understanding is essential to ensuring that policies can effectively address the issue of housing affordability. Opinions on housing affordability are also widely reported on in the media. Therefore how we measure affordability is of critical importance so that policy decisions can be based on evidence rather than conjecture. Although housing affordability has commonly been measured as a simple ratio of income to housing costs, this paper presents an argument for the use of a different measure of housing affordability – the residual income measure that is not commonly used in Australia. The residual income measure is based on the amount leftover from a household's income (the residual income) once all other necessary household expenditures are accounted for. This measure varies for different household types. Measuring housing affordability using this "new" method produces a different picture of housing affordability for home purchases than when using traditional ratio methods. This has implications for our understanding of what is happening in the housing market, the housing industry and implications for creating effective policy to tackle the issue of housing affordability. This paper begins by describing ratio measures of affordability and their limitations. It then outlines the rationale for the residual income measure of affordability, and the methodology used to operationalize this measure using two affordability indicators developed by (insert text) to investigate housing affordability for home purchasers. Two sets of results comparing housing affordability for home purchase in Melbourne using the ratio and residual income methods are then reviewed. The first looks at the maximum affordable housing costs (mortgage repayments) for different incomes. The second determines the maximum affordable dwelling price for each income range (measure one) and thirdly household income required to purchase or rent a property at the median price for any given area is examined (measure two). Key differences between household types and incomes are highlighted.


Abstract : While Space Domain Awareness (SDA), including all of space surveillance and characterization of all space objects and environments, is critical for national and economic security, SDA capabilities cannot be developed independent of cost. This presentation will describe a new approach to SDA being developed by the Defense Advanced Projects Agency (DARPA) and other agencies. This approach endeavors to integrate the data from a wide range of current and future SDA capabilities for a fraction of the current costs by utilizing a new methodology for obtaining data. This approach will not just provide more SDA data for a reduced cost, but has the potential to also increase the amount of knowledge gained from the data.


A number of electron cyclotron codes have been developed in di erent Eu- ropean laboratories, to describe the behavior of EC waves in realistic tokamak plasma scenarios, and to optimize EC heating and current drive e ciency in present, and future devices like ITER. Moreover, integrated modelling is gaining popularity, since it seems to be the optimum approach for modelling tasks as complex as the assessment of future large devices performances. The outcome is presented here of a benchmark exercise for a set of EC codes, performed within the framework of the European Integrated Tokamak Mod- elling Task Force, and based on a standard ITER scenario, considering multiple launching conditions of the EC waves. The advantages o ered by integrated modelling are explored and exploited, and the sources of the small-but-still-present di erences among the various codes results are investigated.


Suppliques are one variant of a widely occuring type of late medieval diplomatic form - the petition - which also includes the bills of the English Chancery and the requetes of the French parlement. All descend from Carolingian supplication, in which petitioners adopted the language and gestures of prayer to address kings, and kings replied in the language of grace and beneficence. In these ways, supplication was constructed to underscore the analogy between the rule of a king and the rule of the King of kings that is represented as the model for earthly kingship. Although later medieval petitions are more streamlined, being geared towards expressing relevant legal issues succinctly, the original resonances of supplication remained. Whether in the papal Curia, the English chancery, or a French royal entry, supplications still emphasize the humility of the petitioner and the clemency of the ruler, and tend to speak of legal issues that require the special, equitable action of a lord whose grace alone can dispense from the rigors of law because he rules in the image of God.

From the perspective of political development,China's consultative political tradition in history and current political consultation system not only provide indigenous resources but also easily form the path dependence for China to develop deliberative democracy.So,unlike the west,China is likely to go through the way of deliberative democracy previous to and bringing along electoral democracy to promote China's democratization process.In fact,from the view of deliberative democracy,China presently is at the transitional stage from consultative politics to deliberative democracy so Chinese government together with society should promote this transformation.


BACKGROUND

The goal of this project was to have nursing documentation drive acuity in a seamless fashion. The success we have encountered was building our framework with standardized nursing language, integrating our stable patient classification system into the framework, and enclosing them online in the computer documentation system.

MAIN CONTENT POINTS

Nursing documentation with NIC and NOC drives the acuity system. Acuity mapping is integrated into the automated nursing documentation system.

CONCLUSIONS

Our success in integrating nursing acuity, NANDA, NIC, and NOC into an online nursing documentation system has been monumental. The healthcare team's documentation can truly identify the patient's needs and provide the necessary acuity to make appropriate assignments, staff according to skill level requirements, and charge patients accurately. The journey from online documentation to integrating NANDA, NIC, and NOC into an online acuity system is just a start in identifying nursing best practices and efficient and effective patient outcomes. Continued research will prove exciting and lead the institution into the next step of patient outcome successes.


[1] We conducted 1-year continuous measurements of in situ compressional wave velocity and attenuation across a distance of 12 m in a vault at the coast of Miura Bay, Japan, using a piezoelectric transducer as the ultrasonic wave source. We detected, for the first time, periodic variations in both velocity and attenuation, with amplitudes of 0.3%, and of 4%, respectively, corresponding to the diurnal and semidiurnal lunar and solar tides. These variations correlate well with the in situ areal strain change due to tidal ocean loading estimated from the strain records about 100 m away from the observational site. Relative minimum velocity and relative maximum attenuation occur at every time of relative maximum areal strain (expansion), suggesting that opening/closure of pores or cracks of in situ rocks is responsible for these periodic variations. The velocity variation shows a remarkable 14-day periodicity corresponding to the spring and neap tides, arising from a nonlinear response of the velocity change to tidal strain change such that the velocity change depends on how slowly the tidal dilatation departs from its peak value.


The recordings made by Alan Lomax in Haiti in 1936-37 (over 1,500 in total), although little known, constitute a priceless repository of Haitian expressive culture, recorded soon after the departure of the American Marines and while Haiti was in the throes of a nationalist and africentric movement. This article examines the complex motivations of Alan Lomax (and the various American ethnographers working concurrently in Haiti, including Melville and Frances Herskovits, George E. Simpson, Harold Courlander, Katherine Dunham and Zora Neale Hurston) in relation to the ideological struggles over race and African diasporic identity in both the U.S. and Haiti. The article demonstrates how Lomax's preconceptions, difficulties in fieldwork, interactions with local culture brokers, and health and funding problems all impacted this legacy.


In an attempt to suppress the frequency variation of a surface acoustic wave device caused by dielectric film deposition on an interdigital transducer (IDT) electrode, we fabricated a one-port resonator and examined the correlation with frequency response and refractive index when a SiOxNy film is deposited. Our data showed that the resonator frequency changes as the refractive index of the SiOxNy film changes. We also found that the frequency drift caused by the SiOxNy deposition can be suppressed if the refractive index is kept in a certain range. Then, we performed a finite element method spectral domain analysis to calculate frequency response using the Young's modulus obtained in this experiment. The calculated frequency response indicated that the refractive index of the SiOxNy film needs to be altered in accordance with the IDT electrode thickness. We suggest that one of the effective ways of controlling the frequency response is to manage the refractive index of SiOxNy.


For the simple performance of standardization and calibration measurements in liquid counter tubes, it was proposed to introduce a sealed radioactive preparation in the form of a hollow cylinder into the measurement space of the counter instead of filling the counters with a radioactive solution. The hollow cylinder can be made from various materials, for example from a metallic plate, on which a radiometal is electrodeposited. By this innovation a decontamination of the counter after each calibration should be unnecessary. (J.S.R.)

The A. analyses the social and political function of the Sufi Orders in the present Senegalese society and he identifies in the problems relating to succession to Caliphate one of the major trends of the contemporary mysticism. On the basis of an unpublished documentation he focuses on the more active reformist movements such as the FAIS, the Senegalese Federation of Islamic Associations, the al-Azhar Institution, the Daa'ira of Murid Students, the Hizbu Tarquiyya and the tijani branch of al-Mustarshidun. Finally a radical movement, the Jamaatou Ibadour Rahmane is especially taken into account and the A. underlines the reasons of his recent popular success between the urban marginal classes.


Multifunctional composite materials have attracted wide attention because they can be applied in many fields, and have great potential for application. The superhydrophobic surface has been favored by scientists in recent years because of its excellent properties. In this paper, carbon fabric (CF) with high porosity, good electrical conductivity and excellent flexibility was selected as substrate. The CF/Zr–TiO2/PDMS composites were prepared by solvo-thermal method on CF and modified by PDMS, which can be used in the fields of self-cleaning, self-healing, oil/water separation, antibacterial, anti-icing and so on. Furthermore, the PDMS modification has no or negligible adverse effect on the important textile physical properties of the CF. The effects of different process parameters on the structure and properties of CF/Zr–TiO2 were studied, and the samples with the best conditions were obtained. The results show that the sample achieves the transformation from superhydrophilic to superhydrophobic after modification. The CF/Zr–TiO2/PDMS composite structure not only shows excellent photocatalytic activity, but also has a certain self-cleaning ability. The samples before and after modification can separate light oil/water and heavy oil/water respectively. Compared with CF/Zr–TiO2, CF/Zr–TiO2/PDMS has better anti-Escherichia coli ability.

Affected by the decreasing economy at home and abroad, from January to November last year,China's textile industry export growth met a great decline. Along with the problems such as the rising labor costs, financing difficulty, etc., textile enterprises' operating pressure has increased, and the domestic textile industry has entered the "big inventory" era.Par t of the orders from the European and


It is shown that with a numerical analysis, based on band structure calculations, using standard local spin density approximations the structural details of K 2 CuF 4 can be reproduced. We compare with Ishizuka et al. 's pressure dependence measured up to 14 GPa with synchrotron radiation. Corrections have to be made on the results of the local density calculations, however, like the "over-binding" which gives too small sizes for the lattice constants. Using the Wien code one can predict Jahn–Teller distortions in the low and in the high pressure phase of K 2 CuF 4 in fair accord with the observation.


*† ‡ A three -phase to single -phase cycloconverter with a digital control is presented. T he cycloconverter in this case is a thyristor based design and requires care in the timing algorithm of the circuit. This algorithm relies solely on a single "reference" signal generated within the digital control. This type of control algorithm is commo nly known as the cosine wave crossing method (CWCM). Throughout this paper, another implementation of this method will be performed with a digital signal processor. A complete design of this power conversion process will allow for a standard three -phase, AC signal to be converted to a reduced frequency, AC signal. Results of this design will be presented with a motor. I. Introduction YCLOCONVERTERS are used in a wide variety of high power applications today to drive both induction and synchronous motors. Some of these applications include steel rolling mills, cement kilns, ore grinding mills, mine winders, and ship propulsion drives. These applications require a variable frequency and variable magnitude power supply. Specifically, they require a powerful voltage input but at a frequency that has been stepped down. A standard three -phase power source operates at a 60Hz frequency per phase. While this can provide a lot of power, the frequency is much too fast to drive a motor at the slow rate required by the applications mentioned. To accommodate these particular applications, a cycloconverter can reduce the frequency of the input to be applied to loads of any power factor. In other words, a cycloconverter is a power conversion device that converts an AC input at one frequency to AC output at another frequency. The basic structure of a cycloconverter consists of two full bridge circuits assembled back to back with thyristors instead of diodes. If two of these bridges are used, one can be used to rectify the input for a time creating a positive half -cycle and the other can invert the signal for a time creating a negative half -cycle [1] . Controlling the duration of each half -cycle will essentially create an output w ith a slower frequency. Making this outp ut signal sinusoi dal in nature depends on accurately timed phase control to determine when thyristors in the circuit should conduct. To derive the timing needed to trigger these thyristors, a control scheme must be implemented. The scheme applied in thi s design is a commonly used method of control called the cosine wave crossing method (CWCM). This method requires fast and accurate sampling of the three input signals through an analog to digital converter (ADC) and a processor that can quickly compare i ts own self -generated "reference" with these signals. To accomplish this proposed design, a digital signal processor (DSP) from Analog Devices is employed [2 ]. The Analog Devices Motor Control (ADMC) 401 DSP board provides the digital control for the ci rcuit with an ex ecution cycle of 26 Millions of Instruction Per Second (MIPS) and a 16 -bit DSP core. The evaluation board provides an ideal test environment by allowing a computer to download the code to the DSP and also do in -circuit debugging all throug h the serial interface. Also, to achieve the design specifications, the ADMC401 board also possesses an 8 channel, 12 -bit analog to digital converter (ADC). Each phase of the input waveform is transformed down to an acceptable voltage and sampled through this flash based ADC. The software that processes the input signal is writte n in an assembly based language which allows for basic math functions along with a fixed point number system. The sinusoidal "reference" signal is produced with the built in tri gonometric functions. It is then applied to the sampled input phases to determine the exact moment when each thyristor should fire. These gating signals are then produced from the 12 digital input/output (I/O) lines of the ADMC401. With each sequence of timed pulses, a single -phase, reduced frequency signal is produced as the output which completes the power conversion process.

This document contains Technical Safety Requirements (TSRs) for the Radioactive and Hazardous Waste Management (RHWM) Division's B695 Segment of the Decontamination and Waste Treatment Facility (DWTF) at Lawrence Livermore National Laboratory (LLNL). The TSRs constitute requirements regarding the safe operation of the B695 Segment of the DWTF. The TSRs are derived from the Documented Safety Analysis (DSA) for the B695 Segment of the DWTF (LLNL 2004). The analysis presented there determined that the B695 Segment of the DWTF is a low-chemical hazard, Hazard Category 3, nonreactor nuclear facility. The TSRs consist primarily of inventory limits as well as controls to preserve the underlying assumptions in the hazard analyses. Furthermore, appropriate commitments to safety programs are presented in the administrative controls section of the TSRs. The B695 Segment of the DWTF (B695 and the west portion of B696) is a waste treatment and storage facility located in the northeast quadrant of the LLNL main site. The approximate area and boundary of the B695 Segment of the DWTF are shown in the B695 Segment of the DWTF DSA. Activities typically conducted in the B695 Segment of the DWTF include container storage, lab-packing, repacking, overpacking, bulking, sampling, waste transfer, and waste treatment. B695more » is used to store and treat radioactive, mixed, and hazardous waste, and it also contains equipment used in conjunction with waste processing operations to treat various liquid and solid wastes. The portion of the building called Building 696 Solid Waste Processing Area (SWPA), also referred to as B696S in this report, is used primarily to manage solid radioactive waste. Operations specific to the SWPA include sorting and segregating low-level waste (LLW) and transuranic (TRU) waste, lab-packing, sampling, and crushing empty drums that previously contained LLW. A permit modification for B696S was submitted to DTSC in January 2004 to store and treat hazardous and mixed waste. Upon approval of the permit modification, B696S rooms 1007, 1008, and 1009 will be able to store hazardous and mixed waste for up to 1 year. Furthermore, an additional drum crusher and a Waste Packaging Unit will be permitted to treat hazardous and mixed waste. RHWM generally processes LLW with no, or extremely low, concentrations of transuranics (i.e., much less than 100 nCi/g). Wastes processed often contain only depleted uranium and beta- and gamma-emitting nuclides, e.g., {sup 90}Sr, {sup 137}Cs, {sup 3}H. Chapter 5 of the DSA documents the derivation of TSRs and develops the operational limits that protect the safety envelope defined for this facility. The DSA is applicable to the handling of radioactive waste stored and treated in the B695 Segment of the DWTF. Section 5 of the TSR, Administrative Controls, contains those Administrative Controls necessary to ensure safe operation of the B695 Segment of the DWTF. A basis explanation follows each of the requirements described in Section 5.5, Specific Administrative Controls. The basis explanation does not constitute an additional requirement, but is intended as an expansion of the logic and reasoning behind development of the requirement. Programmatic Administrative Controls are addressed in Section 5.6.« less


In this paper, we classify nonsymmetric Dunkl-classical linear functionals. Firstly, we reduce the characterization of a Dunkl-classical linear functional given by the first author in a previous work to a Tμdistributional equation of Pearson's type. Secondly, after rescaling the parameters, we prove that the unique nonsymmetric Dunkl-classical linear functional is the perturbed generalized Gegenbauer form.

A probabilistic machine learning method is applied to icing related production loss forecasts for wind energy in cold climates. The employed method, called quantile regression forests, is based on the random forest regression algorithm. Based on the performed tests on data from four Swedish wind parks available for two winter seasons, it has been shown to produce valuable probabilistic forecasts. Even with the limited amount of training and test data that were used in the study, the estimated forecast uncertainty adds more value to the forecast when compared to a deterministic forecast and a previously published probabilistic forecast method. It is also shown that the output from a physical icing model provides useful information to the machine learning method, as its usage results in an increased forecast skill when compared to only using Numerical Weather Prediction data. A potential additional benefit in machine learning for some stations was also found when using information in the training from other stations that are also affected by icing. This increases the amount of data, which is otherwise a challenge when developing forecasting methods for wind energy in cold climates.


Video conferencing and high quality video-on-demand services are very desirable for many Internet users. However, Internet access channels ranging from wireless connections to high- speed ATM networks mean great heterogeneity with respect to bandwidth. Hierarchical video encoders that scale and distribute video data over different layers enable users to adapt video quality to the capacity of their Internet connection. However, the construction of the layers at the encoder determines the video quality that can be expected at the receiver. To achieve an optimal configuration of the different layers with respect to visual quality, we propose a hybrid scaling algorithm that scales video data both in spatial and temporal dimension. Using a quality metric based on properties of the human visual system our algorithm calculates an optimal ratio between spatial and temporal information. Additionally, we present experimental results that demonstrate the capabilities of our approach.

Environmental justice concerns, in part, the distribution of both environmental hazards and nuisances such that impoverished communities, particularly impoverished communities of color, contend more with the effects of industry than those who are affluent. As communities of color have organized to confront this problem, their claims of injustice have revealed significant issues across all sectors of environmental governance, both in the U.S. and internationally, and reflect failures of representative institutions in urban land management. In this manuscript, we derive a socio-spatial approach to management of facility siting decisions based on the research in environmental justice. Then we discuss some reforms to facility siting that have been proposed and implemented in the U.S., Canada, and western Europe over the course of three decades, and how these reforms can improve the legitimacy of facility siting decisions.


A method for finding the optimal control of linear singular systems with a quadratic cost functional using piecewise linear polynomial functions is discussed. The state variable, state rate, and the control vector are expanded in piecewise linear polynomial functions with unknown coefficients. The relation between the coefficients of the state rate with state variable is provided and the necessary condition of optimality is derived as a linear system of algebraic equations in terms of the unknown coefficients of the state and control vectors. A numerical example is included to demonstrate the validity and the applicability of the technique. Copyright © 2002 John Wiley & Sons, Ltd.


One of the most critical missions of sonar is to capture deep-sea pictures to depict sea floor and various objects, and provide an immense understanding of biology and geology in deep sea. Due to the poor condition of underwater acoustic channel, the captured sonar images very possibly suffer from several typical types of distortions before finally reaching to users. Unfortunately, very limited efforts have been devoted to collecting meaningful sonar image databases and benchmark reliable objective quality predictors. In this paper, we first generate a sonar image quality database (SIQD), including 840 images. All distorted images were collected without artificially introducing any distortions beyond those occurring during compression and transmission. The subjective quality assessment was conducted for gathering mean opinion score (MOS) to represent the image quality and existence of target (EOT) which describes whether the image is useful. Based on the built SIQD database, state-of-the-art general image quality metrics were found to poorly correlate with "ground-truth" MOS. As a consequence, this paper further develops a novel full-reference local entropy backed sonar image quality predictor (LESQP). The experimental results demonstrate the superiority of our LESQP metric over the available quality measures.


In today's web search generates a large amount of data and search contents. Text based searching is most popular technique to search content based on available information. In social websites like Flicker, YouTube, Face book they provide features to users that create information, share information and allows the users to search information based on created tag, comment and annotation. This Create the user-generated metadata in very large amount which can be utilized for management and information or media retrieval. It's found that use of tag, comment, and annotated data is convoluted in personalized search system. With Personalize search technique is improved by using user preferences and query-related search intention into user-specific topic spaces. In this paper the given model is tested for single word based query and showing satisfactory result. Keywords— Personalize search, Non-Personalize search, User preferences, Image annotation.


Slang is a predominant form of informal language making flexible and extended use of words that is notoriously hard for natural language processing systems to interpret. Existing approaches to slang interpretation tend to rely on context but ignore semantic extensions common in slang word usage. We propose a semantically informed slang interpretation (SSI) framework that considers jointly the contextual and semantic appropriateness of a candidate interpretation for a query slang. We perform rigorous evaluation on two large-scale online slang dictionaries and show that our approach not only achieves state-of-the-art accuracy for slang interpretation in English, but also does so in zero-shot and few-shot scenarios where training data is sparse. Furthermore, we show how the same framework can be applied to enhancing machine translation of slang from English to other languages. Our work creates opportunities for the automated interpretation and translation of informal language.

Dry friction between macroscopic solids can be understood in terms of the elastic (static regime) versus plastic (dynamic regime) responses to a shear stress of a set of dilute micrometric adhesive contacts. When pinned, such a system is the seat of two distinguishable slow, quasi-logarithmic aging dynamics: - a geometric aging process, originating from the bulk of the contacting asperities, which results in the increase of the real area of contact. - a structural one, taking place within the nm-thick adhesive layers, which behave as 2D confined soft structural glasses. Both mechanisms give rise to associated dynamic rejuvenation phenomena, akin to those observed in threshold fluids, which govern the rich variety of frictional dynamics exhibited by extended systems.

N.Karthik Dr.M.Surya Kalavathi Asst.Professor in EEE Department Professor in EEE Department Bapatla Engineering College JNTUHCEH, Hyderabad Bapatla email id: firstname.lastname@example.com email id:firstname.lastname@example.com Abstract—This paper presents single phase series and shunt active filters to improve power quality by reducing various power quality problems including current harmonics, voltage sag, voltage swell and voltage flicker. Voltage quality is improved by series active filter by injecting compensating voltage and current quality is improved by shunt active filter by injecting compensating current. Control strategy of series active filter contains two main loops, one is for output voltage control loop and another one is DC link voltage control loop. Control strategy of active filter should maintain constant voltage across DC side of the H Bridge and second objective is to maintain harmonic free sinusoidal source current in phase with source voltage. Simulation and experimental results are carried out for both filters to check the effectiveness of proposed control strategies.

Results of the first experiment in which Bragg diffraction of a focused x-ray beam was utilized to obtain depth sensitive structural information are presented. Silicon-on-insulator (SOI) layers of 4.5 to 25 μm thick were studied. The beam was focused by a circular zone plate. A beam stop and an order sorting aperture were used to reduce the contribution of the background radiation into diffracted intensity. Diffraction patterns were recorded by a CCD detector placed in the focus of the zone plate. Spatial distributions of the recorded intensity in the scattering plane revealed variations of the lattice constant within the layers. Incoherent scattering was observed out of the scattering plane thus providing a new method to study diffuse scattering. Computer simulations of the intensity patterns produced by the interface between two layers with the lattice constant mismatch are presented.

Pteropus giganteus is among the largest flying bat species of the world and play important role in pollination and seed dispersal. It prefers roost on tall trees. We conducted the this study from November, 2007 to February, 2009 to assess the roost site selection of P. giganteus in Girwa tehsil of Udaipur district, Rajasthan, India. Road surveys were performed to identify the roosting sites. After identification of roosting sites, name of the sites, number of bats and other characteristics were noted. During the study, a total of 14 roosting sites were identified where bats were rooted on trees. Trees were belonged to eight species and five families. Presence of high tree densities and numerous waterbodies in the tehsil might be a reason for a sound number of the species.


Although point patterns have been intensively studied, the problem of how to extract the structure information from a clustered spatial point pattern still remains. The author put forth the H function, which is capable of measuring the distributive characteristics of a two dimension discrete point set in a square, and derives its analytical expression theoretically based on geometric probability. Then a general algorithm to extract the structure information of a two dimension discrete paint set is designed and implemented by means of H function. Subsequently the algorithm is employed to process a clustered spatial point pattern consisting of real residential coordinate data. Its structure information is derived and visualized. After that, generate the Delaunay Triangulation and Voronoi Diagram of the same spatial point pattern respectively, keep the vertices of 1/10 and 1/100 Delaunay triangles with the least area in the point set to form two graphs, and keep the generators of 1/10 and 1/100 Voronoi polygons with the least area in the point set to form another two graphs, make a contrast between the result of the algorithm with each of the four graphs. It turns out that although Delaunay Triangulation and Voronoi Diagram are capable of indicating the local point density of a clustered spatial point pattern, they are explicitly limited in terms of extracting its structure information, while the algorithm introduced in this article can effectively perform doing so.


This paper proposes architectural refinements, server-driven metadata prefetching and namespace flattening, for improving the efficiency of small file workloads in object-based storage systems. Server-driven metadata prefetching consists of having the metadata server provide information and capabilities for multiple objects, rather than just one, in response to each lookup. Doing so allows clients to access the contents of many small files for each metadata server interaction, reducing access latency and metadata server load. Namespace flattening encodes the directory hierarchy into object IDs such that namespace locality translates to object ID similarity. Doing so exposes namespace relationships among objects (e.g., as hints to storage devices), improves locality in metadata indices, and enables use of ranges for exploiting them. Trace-driven simulations and experiments with a prototype implementation show significant performance benefits for small file workloads.

Abstract There is concern over the decline of aspen and the lack of successful regeneration due to excessive browsing of aspen suckers by cattle and other wild and domestic ungulates. We conducted a 2-yr study on Lassen National Forest, California, to aid development of cattle grazing strategies to enhance aspen regeneration. We evaluated seasonal biomass, nutritional quality, and utilization by cattle of aspen suckers, aspen herbaceous understory vegetation, and meadow herbaceous vegetation within six aspen–meadow complexes. Aspen suckers had greater nutritional quality compared to aspen understory and meadow vegetation regardless of season or year. Nutritional quality declined with season in all three vegetation types. Early-growing season foraging by cattle focused on meadow and aspen understory vegetation. Mid-growing season decreases in meadow and aspen understory nutritional quality coincided with a marked increase in utilization of aspen suckers. By late-growing season, utilization on aspen suckers was significantly greater than aspen understory or meadow vegetation. Managers can use early-growing season grazing to reduce aspen consumption by cattle, set stocking rates so that adequate herbaceous vegetation is available throughout the growing season, provide nutritional supplements to reduce demand for nutritious aspen suckers, construct protective fencing, and implement grazing systems that insure years with mid- and late-growing season rest from heavy browsing.


We discuss photo- and leptoproduction of J/ψ mesons at energies ranging from those of fixed-target experiments up to those of HERA. Elastic and diffractive production as well as various inelastic processes are studied. We investigate the range in which J/ψ production is described by photon-gluon fusion in the color-singlet model. We show how inelastic J/ψ production at HERA can be used to extract the gluon density. We estimate an accessible range of 3×10−4<x<0.1 and discuss sources of errors in the reconstruction of the gluon density at HERA.


ABSTRACT Marine plastic has many negative impacts on coastal countries, including Vietnam. Vietnamese waters face problems of marine pollution owing to plastic waste. There are few studies on controlling marine plastic waste generated by marine-based activities. Therefore, this paper aims to provide a general view of marine plastics based on existing academic articles, and the impacts on marine animals and on human health. The paper includes a brief account of the quantity of marine plastic waste on coastal Vietnam and offers some recommendations for Vietnam to minimise and manage plastic waste generated by ships.
