From the point of view of an operating system, a computer is managed and optimized in terms of the application programming model and the management of system resources. For the TFLOPS system, the problem is to manage and optimize large scale parallelism. This paper looks at the management in terms of three key topics: memory management, communication, and input/output. For memory management, we discuss some of the design decisions made including the appropriate use of demand paged virtual memory in the system. For communication, we describe the software protocols and interactions that permit a system of 4500 nodes to approach the maximum hardware performance. For I/O, we look at the problem of funneling data from many computation nodes to a small number of external devices.


Production line in manufacturing industry usually is made up of several processes and must go through performance measurement to determine whether they are efficient or inefficient. The extended Data Envelopment Analysis (DEA) which is the Network Data Envelopment Analysis (NDEA) is developed to look inside the production line and find the source of inefficiency of each sub process. However, the model can only measure the efficiency of the production line for current time periods only without considering the past time periods and detect any changes of performances that might occur during the time periods. In this paper, we proposed a Dynamic Network DEA model that can be used to measure the performance of the same production line by taking into account any changes according to time. We treat these changes as a Decision Making Units (DMUs) which is the entity that are going to be measured. This dynamic network model only considered the data inputs from different time periods. Our goals of developing the DNDEA model on the production line are to identify the inputs and outputs required and to consider the relationship and connection between each of the processes in the production line and thus measure the performance of the entire production line. The expected outcome of this paper is to propose a conceptual model that can be used for performance measurement in manufacturing production line dynamically.


Practical guidelines are required for the design and operation of complicated catalytic packed-bed reactors. Primary among design considerations is the avoidance of operating regions of high parametric sensitivity, in which small changes in operating conditions can lead to thermal runaway in the reactor. Existing criteria for predicting these regions rely on complex mathematical formulations for differential sensitivity between input and output variables. The present work centers on the development of practical design criteria for avoiding reactor instability and temperature sensitivity in multitubular packed-bed reactors. A set of simple guidelines is proposed for the sizing of reactors and proper selection of operating conditions. The implications of these open-loop sensitivities for a controlled reactor are investigated. It is shown through simulation studies that violation of the proposed criteria leads to control problems and difficulty in operating at the design point.

By using a nickel complex with an N-phosphinomethyl-N-heterocyclic carbene ligand (NHC-P), reducing ability and thermal stability of the complex were improved considerably compared to the previously reported bipyridine and bisphosphine complexes, and acrylate salt was prepared from ethylene and CO2 with the highest TON ever reported for nickel systems even without using metallic zinc. Oxidative cyclization of ethylene and CO2 on the NHC-P nickel complex was found to proceed very rapidly compared to the previous systems.


TROUBLING NATIONHOOD IN U.S. LATINA LITERATURE: Explorations of Place and Belonging. By Maya Socolovsky. New Brunswick, NJ: Rutgers Univer- sity Press. 2013.Maya Socolovsky's, Troubling Nationhood in U.S. Latina Literature: Explo - rations of Place and Belonging is an analysis of ten novels written by U.S. La- tina writers published between 1989 and 2004. The main purpose of Socolovsky's work is to demonstrate how a selected group of literary narratives remaps Latin America as part of the United States through a bi-directional process of belonging and unbelonging to the nation. Central to her argument are the characters' personal blended narratives through which they reimagine themselves as being part of the U.S. national identity as well as retain their own Latin American cultural heritage. These new identities disrupt the general perceptions of nationhood, generating a process of categorizing these new Latinos as the "other." Furthermore, Socolovsky argues that racialized notions of citizenship have recently changed to cultural rac- ism, which emphasizes cultural differences as threatening the national identity of the United States.The introduction provides an overview of the text's principal argument; ex- plaining how recent literary works question the cultural and political hegemony of the United States, which began with the historical expansion of its territory, and reflected through the mentality of Manifest Destiny. The text builds on the research of prominent scholars including Edward Soja, Mary Pat Brady, Juan Flores, Jose David Saldivar, and Ilan Stavans. Socolovsky cites their research to help the reader understand the framework and analysis of her own work, a needed contextualization of the historical and political background of the selected literary works. Utilizing Denise Chavez's novels The Last of the Menu Girls (2004) and Face of an Angel (1994) the analysis of the first chapter focuses on the geographic landscape of the borderlands "as a space of dislocation, unease, and disease" (29). According to Socolovsky, the realities and experiences lived by the characters in a complex environment triggers "symptoms of disease that can only be healed through the imaginary blurring and conjoining of Mexico and the United States' nation-spaces" (29). While the first chapter establishes the borderlands as a continuous contested space of belonging and unbelonging, the second chapter turns the lens to the literary work of Ana Castillo's Sopogonia (1994) and Sandra Cisneros' Caramelo (2002). In both novels, the analysis centers on the concept of mestizaje as a way to challenge the geographic conceptions of nationhood and challenging representations of citizenship in the heartland of the United States. …


Biaxial film production is a complex industrial process with large time_delay, it includes two stretch processes: longitudinally and laterally, the disturbances often occur in the film_forming part. We propose in this paper a cascade generalized predictive control (CGPC) real_time algorithm developed for this control system. The use of CGPC algorithm instead of classical PI cascade controller is now very well applied to industrial practice due to the quick rejection of the effect of disturbances in the inner loop, the master loop takes into account more information about the future using GPC algorithm to give the setpoint of the inner loop.


In this paper, a 60 GHz dipole antenna with excellent performance such as wideband impedance matching, medium gain and high efficiency (> 90%) is designed and tested. Also, the antenna is then placed inside a metal box and tested. The dipole-box antenna not only maintains good impedance matching but also demonstrates a gain of 10–11 dB and narrower H-plane radiation patterns than the standard dipole antenna. The dipolebox antenna is ideal for placement inside a laptop or a portable 60 GHz communications device since it is shielded from the environment and is not affected by nearby metals.


Numbers are ubiquitous in modern political communication and discussions. The relationship between numbers and policy attitudes is therefore a key issue for public opinion research. This article explores the degree to which voters can translate their ideological predispositions into numerical policy preferences. Further, we theorize and investigate how numerical framing can affect this translation of ideology into numerical preferences. Using a survey experiment, we show that voters' ideological differences are reflected in their numerical preferences, but that they are also highly affected by numerical framing, specifically gain–loss framing and unit framing. These results have implications for our theoretical understanding of framing effects, and they suggest that politicians can markedly affect the attitudes of voters through strategic use of numerical framing.


In this paper we study harmonic analysis on the Einstein gyrogroup of the open ball of R, n ∈ N, centered at the origin and with arbitrary radius t ∈ R, associated to the generalised Laplace-Beltrami operator Lσ,t = ( 1− ‖x‖ 2 t2 )∆− n ∑ i,j=1 xixj t2 ∂ ∂xi∂xj − κ t2 n ∑ i=1 xi ∂ ∂xi + κ(2− κ) 4t2  where κ = n + σ and σ ∈ R is an arbitrary parameter. The generalised harmonic analysis for Lσ,t gives rise to the (σ, t)-translation, the (σ, t)-convolution, the (σ, t)spherical Fourier transform, the (σ, t)-Poisson transform, the (σ, t)-Helgason Fourier transform, its inverse transform and Plancherel's Theorem. In the limit of large t, t→ +∞, the resulting hyperbolic harmonic analysis tends to the standard Euclidean harmonic analysis on R, thus unifying hyperbolic and Euclidean harmonic analysis.

The results of this study will provide a theoretical foundation on the research of identifying factors affecting users" intention to adopt the mobile payment services. We expect that the crucial information about main factors influencing the intention to adopt, such as, self-efficacy, familiarity, simplicity, stability, ubiquity, and personalization, will be offered to working-level officials of the company.


The Tank Waste Remediation System (TWRS) mission is to store, treat, and immobilize the highly radioactive Hanford Site tank wastes and encapsulated cesium and strontium materials in an environmentally sound, safe, and cost effective manner. Additionally, the TWRS conducts, as part of this mission, resolution of safety issues associated with the wastes within the 177 underground radioactive waste tanks. Systems engineering principles are being applied to determine the functions and establish requirements necessary for accomplishing the TWRS mission (DOE 1994 draft). This systematic evaluation of the TWRS program has identified key decisions that must be executed to establish mission scope, determine requirements, or select a technical solution for accomplishing identified functions and requirements. Key decisions identified through the systematic evaluation of the TWRS mission are presented in this document. Potential alternative solutions to each decision are discussed. After-discussion and evaluation of each decision with effected stakeholder groups, the US Department of Energy (DOE) will select a solution from the identified alternatives for implementation. In order to proceed with the development and execution of the tank waste remediation program, the DOE has adopted a planning basis for several of these decisions, until a formal basis is established. The planning bases adoptedmore » by the DOE is continuing to be discussed with stakeholder groups to establish consensus for proceeding with proposed actions. Technical and programmatic risks associated with the planning basis adopted by the DOE are discussed.« less


The ionization characteristics of liquid krypton irradiated with fast electrons, y-rays and a particles were investigated . These studies aim at a better understanding of the properties of liquid rare gases and their use in radiation detectors for a variety of physics and astrophysics applications . Similar studies with liquid argon and liquid xenon have already been reported by us [1,2] . The availability of data on free-ion yield and energy resolution response to different ionizing radiations for the three liquids should enable the refinenient of existing recombination theories . With their present limitations these theories are still unable to fully explain the experimental results on the energy resolution of liquid ionization chambers . Our experiments with liquid krypton were also triggered by the need of a more precise determination of the W-value, the average energy required to produce an electron-ion pair . Results on this will be presented in a forthcoming publication . In this paper we report the results on the studies of the charge and energy resolution response of liquid krypton to fast electrons, y-rays and a particles .


This paper presents the two new ITU-T Recommendations G.722 Annex D and G.711.1 Annex F, which are stereo extensions of the wideband codecs ITU-T G.722 and G.711.1 and their superwideband extensions (G.722 Annex B and G.711.1 Annex D). An embedded scalable structure is used to add stereo extension layers on top of the wideband or superwideband core coding. Wideband stereo modes are supported at the bit rates of 64/80 and 96/128 kbit/s for G.722 and G.711.1 (respectively), while superwideband stereo modes are supported at 80/96/112/128 and 112/128/144/160 kbit/s. The parametric stereo coding model is based on a frequency domain downmix, wideband inter-channel differences estimation, quantization and synthesis, low complexity coherence analysis and synthesis, stereo transient detection and stereo post-processing. An overview of formal ITU-T characterization listening tests illustrates the performance of these codecs.


e18550 Background: Early detection through screening mammography has been shown to decrease breast cancer mortality. Screening mammography rates remains low among racial/ethnic minorities and patients with socioeconomic deprivation (SED). Most studies evaluating the role of area-level social determinants of health and breast cancer screening have included only a small number of variables; in this study, a comprehensive and granular measure of socioeconomic deprivation (SED) which included 17 variables was used to determine an association with screening mammogram completion. Methods: A retrospective cohort study was conducted at an academic hospital system between 2014-2020 to identify asymptomatic female patients who received screening mammogram referrals in their primary care clinic after they were deemed eligible per screening guidelines. Patients were assessed for mammogram completion at their annual visits. SED was evaluated using the area deprivation index (ADI), a measure of 17 variables including education, housing, and income at the census block group level. Other covariates analyzed were insurance status, age, and race. Chi-square test, Kruskal-Wallis test and a multivariate logistic regression model were used for statistical analysis. Results: 856 women were referred for screening mammography. 324 (38%) underwent mammogram. Patients with high, moderate, and low SED comprised 69 (8%), 287 (34%) and 500 (58%) of the cohort, respectively. In multivariable analysis, SED and race were not associated with higher screening rates. Uninsured and self-pay patients had the lowest odds of screening mammography completion (AOR 0.22; 95% 0.08, 0.60) and Medicare patients had decreased odds of mammogram completion relative to privately insured patients (AOR 0.64; 95% CI 0.43, 0.97). Older age was associated with a slightly higher odds of mammography completion (AOR 1.02; 95% CI 1.00, 1.04). Conclusions: The receipt of screening mammography was low among all patients relative to previously published rates. Uninsured/self-pay status was the strongest indicator for completion of mammography. Additional research is needed to understand the barriers that may influence mammography completion in this population with high socioeconomic deprivation.

This paper studies the payout policy of Italian firms controlled by large majority shareholders (controlled firms). The paper reports that a firm's share of dividends in total payout (dividends plus repurchases) is negatively related to the size of the cash flow stake of the firm's controlling shareholder and positively associated with the wedge between the controlling shareholder's control rights and cash flow rights. These findings are consistent with the substitute model of payout. One of the implications of this model is that controlled firms with weak corporate governance set-ups, in which controlling shareholders have strong incentives to expropriate minority shareholders, tend to prefer dividends over repurchases when disgorging cash.


Anxiety and depression are the most usual reactions following different surgical procedures. The aim of this investigation was to evaluate the presence of anxiety and depression in patients suffering from cervical cancer. Results before conizations and before surgery were compared so as to ascertain if there was statistically significant difference between these two groups of patients. The investigation included 40 patients. Twenty patients underwent conizations, while other 20 patients underwent radical hysterectomy. Hamilton depression rating scale and Hamilton anxiety rating scale were used in this investigation. Results were analyzed using Independent Samples ttest. The difference between average values of depression for t=2.87>t=2.02 i p<0.05 was statistically significant. There was a defference in results between group of patients with conization and group of patients with radical hysterectomy. Subjects with radical hysterectomy had higher level of depression. The difference between average values of anxiety for t=0.87<t=2.02 i p>0.05 was not statistically significant. It can be concluded that the score on Hamilton anxiety rating scale before surgery was equal in both groups of patients. The results show that the fear of surgery exists, regardless of the kind of surgery. Acta Medica Medianae 2008;47(2):49-53.

Experimental results are presented that describe the effects of embedded, longitudinal vortices on heat transfer and film injectant downstream of two staggered rows of film cooling holes with compound angle orientations. Holes are oriented so that their angles with respect to the test surface are 30 deg in a spanwise/normal plane projection, and 35 deg in a streamwise/normal plane projection. A blowing ratio of 0.5, nondimensional injection temperature parameter θ of about 1.5, and freestream velocity of 10 m/s are employed. Injection hole diameter is 0.945 cm to give a ratio of vortex core diameter to hole diameter of 1.6-1.67 just downstream of the injection holes (x/d = 10.2). At the same location, vortex circulation magnitudes range from O.15 m 2 /s to O.18 m 2 /s


Purpose – The purpose of this paper is to examine the effects of a self‐managed transition process on the performance of mid‐level managers, specifically company commanders serving in the US Army.Design/methodology/approach – The transition process provided the new commanders with a flexible outline of topics used for interviewing key personnel within the larger organization (battalion) prior to and immediately following assumption of command. The authors measured the performance of commanders using a standardized Battalion Command Evaluation Form completed by the battalion commander. In addition, the effects of leader experience and locus of control were examined.Findings – It was found that use of the transition process enhanced the performance of company commanders who had an external locus of control and/or did not come directly from a job proximal to command.Research limitations/implications – The paper provides a model that can be used with mid‐level managers in order to minimize the performance def...


This paper provides an overview of selected literature on the impact of social background on educational opportunity in Sweden. Both a sociological and an economic perspective are applied. It is found that the social stratification in Sweden has decreased compared to other comparable countries and that this probably is due to increased equality outside of the educational sector and increased economic safety. However the pattern of social stratification in higher education, though weaker, persists with few changes. It is also found that the return to education increases with social class and the economic incentives to study at university level are, on the whole, lower for lower classes.


Maternal mortality is a significant public health problem and an important indicator of the quality of health care both nationally and internationally. The death of a mother during pregnancy, childbirth, or postpartum is one of the greatest tragedies that can occur within a family, with wide-ranging consequences for the index child, other family members, and the larger society. Maternal mortality also represents the ultimate failure of perinatal medical care. In the United States, the National Vital Statistics System (NVSS) is the source of official maternal mortality statistics used for both subnational and international comparisons. The researchers reviewed the history of vital statistics maternal mortality data in the United States, finding that studies based on data from the 1980s and 1990s identified significant underreporting ofmaternal deaths in the NVSS. To improve the reporting of maternal deaths, a pregnancy question was added to the 2003 revision of the United States standard death certificate. The question has checkboxes to ascertain whether female decedents were not pregnant within the past year, pregnant at the time of death, not pregnant but pregnant within 42 days of death, pregnant 43 days to 1 year before death, or unknown whether pregnant within the past year. The addition of the standard pregnancy question resulted in a substantial increase in reporting of maternal deaths. As more states adopted the standard pregnancy question by 2015 (except for Alabama, California, andWest Virginia), more recent studies identified significant overreporting of maternal deaths from states using the pregnancy question. A recent Centers for Disease Control and Prevention report from maternal mortality review committees in 4 states found that 15% (97/650) of reported maternal deaths were not maternal deaths at all, because the women involved were confirmed to be not pregnant or postpartum within 1 year of death. The same study also found that the checkbox identified cases, particularly during pregnancy or late postpartum, that were identified only because of the checkbox, and with no other evidence that the case was a maternal death. The researchers concluded that the errors of overcounting were predominantly because of errors in the pregnancy checkbox and ultimately concluded that it is insufficient to just add a question to a data collection form; training and quality control are essential to make sure that the information is reported accurately. This has impacted the related data system of the Pregnancy Mortality Surveillance System, and that the nature of the Pregnancy Mortality Surveillance System and the problems in the NVSS have lead to "considerable wasted time and effort as these volunteerbased committees examine deaths reported as maternal, which are not maternal at all." The researchers also said that the failure of the US government to publish an official maternal mortality rate since 2007 has also led to a deficit of information both nationally and internationally. They urge quality improvement efforts that need to focus on improving the quality and validity of the pregnancy checkbox data, urging the National Center for Health Statistics, the government agency responsible for the NVSS, to take concrete action to improve the measurement of maternal mortality in the United States, a step they see as essential in saving women's lives.

Note: This is a chapter of my dissertation titled 'That thesis: a competition mechanism for anaphoric expressions', where I explore different expressions that are used to refer to familiar entities across languages. I propose that the difference in distribution and interpretation of anaphoric expressions result from a competition, and that this competition can be derived from underlying denotations. This chapter investigates the distribution and interpretation of different anaphoric expressions in American Sign Language (ASL) and how the competition mechanism can account for the data. The majority of this work can be read independently from the rest of the dissertation, but there are some references to the competition mechanism of anaphoric expressions that I propose in previous chapters, especially in the final analysis section (with short reminders). A manuscript that combines this chapter with a more elaborate discussion of the competition mechanism is in preparation.


The headlines about contaminated heparin and tainted peanuts have put pressure on FDA to improve its methods for detecting unsafe medical and food products and to take swift action when problems emerge. The complaints are prompting the Obama administration to provide more resources for FDA while Congress weighs expanding agency operations and enforcement authority.


Designing of the mathematical model is based on rigorous electromagnetic equations for antenna system as thin-wire dipoles above perfectly conductive screen which corresponds the given continuity restrictions. This model must consider mutual couple between screen's surface current j→s and current distribution of dipoles. It allows to calculate antenna system's pattern for arbitrary directions and getting matching for frequency band. Antenna, antenna array, optimization, modeling, numerical methods


An integral equation method for the Dirichlet problem for the biharmonic equation is proposed. It leads to a $2 \times 2$ matrix integral equation system. By taking suitable norms on the spaces of density functions, the Fredholm operator theory can be used to prove the solvability. The kernels in this system are relatively complicated. Therefore, especially when a high-order polynomial approximation is used for a numerical purpose, it is costly to evaluate the integrals that appear in the numerical system. A discrete Galerkin method that has shown superb convergence is proposed here, as in [K. Atkinson, J. Integral Equations Appl., 1 (1988), pp. 343–363] and elsewhere. When the boundary functions are smooth, exponential convergence is observed.


Book Review: Geophysics for the Mineral Exploration Geoscientist . (2014) By Michael Dentith and Stephen T. Mudge. Cambridge University Press. ISBN: 9780521809511 Available in hardback or e-book, 438 pp. $68.

At the outset, Dentith and Mudge state that the goal of this book is to explain "...the principles and modern practice of geophysics in the search for mineral deposits. ... from a perspective relevant to a mining industry geologist." I would add that this book is relevant to all geoscientists.

A good description of Geophysics for the Mineral Exploration Geoscientist is provided in the preface: "Our aim is to provide an understanding of the physical phenomena, the acquisition and manipulation of geophysical data, and their integration and interpretation with other types of data to produce an acceptable geological model of the subsurface." The authors present the essential mathematical formulae necessary to explain the techniques described. The text offers detailed descriptions of petrophysical properties and their importance, and techniques used to interpret the geological significance of the data. This volume is for the all those involved in mineral exploration from geologist and geophysicists to mining engineers and managers. Note: A basic physics and calculus course are required.

Throughout this book the link between geological and geophysical measurements, that is petrophysics, is …


Aiming at the problem of wire extension stability in aluminum alloy pulsed MIG welding process, the influence of wire feed speed on wire extension is identified and the mathematic model has been set by the step response experimentation. According to the actuality problem of routine PID control, a self-tuning fuzzy PID system in a dynamic process was designed to improve the adaptability and the control accuracy,and system simulation was conducted by using the Simulink toolbox of MATLAB, and the optimum control parameters was obtained, then the real-time control for wire extension was carried out based on xPC target real-time environment. The results show that the obtained identification model can reflect the change law of wire extension well and the designed self-tuning fuzzy PID system can control the wire extension effectively in aluminum alloy pulsed MIG welding and also have fast response and good robustness.


The design-oriented planner has a major responsibility for providing inputs to the planning process, in organizing and guiding it, in educating those involved in it, in specifying the nature of the output that is required, in providing criteria by which the output can be evaluated, and in facilitating such evaluation. The design-oriented planner must be competent in the use of the methods, techniques, and tools of both the clinician and the researcher. He need not be as skilled in the use of their instruments as they are, but he must know them well enough to be able to use those who have these skills effectively. He must do more than this: he must know how to design and invent, and he must be able to encourage and facilitate the efforts of others to do so. He must be a generalist who is familiar with the capabilities and limitations of relevant specialists; he must be a humanist as well as a scientist; and he must be as much at home with art as he is with technology. Finally, he must be as concerned with the qualities of life as he is with its quantities.


The purpose of this research is to develop an efficient single-phase grid-connected PV system using a better performing asymmetrical multilevel inverter (AMI). Circuit component reduction, harmonic reduction, and grid integration are critical criteria for better inverter efficiency. The proposed inverter's optimized topology requires seven unidirectional switches, three symmetric dc sources, and three diodes to produce an asymmetric fifteen level output; whereas, the same configuration will generate 7, 11, and 15-level output with an appropriate choice of dc source magnitudes. It is possible to reduce inverter losses and boost efficiency by decreasing the number of switches used. The integration of an asymmetric 15-level inverter with a grid-connected solar photovoltaic system is discussed in this article. A grid-connected solar photovoltaic (GCSPV) system is modelled and simulated using an asymmetric 15-level inverter. The dc sources of the 15-level inverter are replaced with PV sources. The results were analyzed with different operating temperatures and solar irradiance conditions. The GCSPV system is controlled by a closed-loop control system using Particle Swarm Optimization (PSO), Harris Hawk Optimization (HHO), and Hybrid Particle Swarm Optimization-Genetic Algorithm (PSOGA) based Proportional plus Integral (PI) controllers. Grid voltage, grid current, grid power, and total harmonic distortion (THD) of grid currents were analyzed. The performance of the 15-level asymmetric inverter was evaluated by comparing the THD of the grid current and the efficiency of the grid-connected photovoltaic system.


a very valuable report by A. P. Luff, embodying the results. The importance of the question was also urged last year by A. Dickson Wright, in an address given before the Medical Society of London, in which he estimated the incidence of chronic ulcer of the leg in this country as 1 in 180, and stressed the grave economic loss resulting from disablement caused by this very chronic and intractable condition. Another important aspect of the " leg ulcer" problem is, in my opinion, the sanitary one, because every indolent ulcer of the leg is the breeding ground of a great variety of pathogenic organismsstaphylococci, streptococci, and others. Sabouraud defines these ulcers as " chancre streptococcique." There is a certain potential danger of infection from such patients to those around them, especially if erysipelas happens to complicate the ulcer, and the patient becomes afterwards a " carrier" of this disease. The crowded conditions under which the poor live makes the spreading of any infection so much easier. In a woman of child-bearing age such an ulcer miay become a potential source of sepsis during her pregnancy or puerperium. There is also a possibility of conveying sepsis to a maternity case by the "handy woman " suffering from a neglected leg ulcer if she is in attendance on the case.


Fifth-generation (5G) systems are being designed not only to face the unprecedented growth of mobile data traffic forecasted for the coming years but also to support other multiple and diverse use cases associated with new market segments and vertical industries (e.g., connected cars, smart cities, e-health, and smart factories). Hence, 5G systems are envisioned to become flexible and versatile network infrastructures that can be leveraged through a wide range of service-delivery models (e.g., neutral network hosting, network as a service, and private networks) and operators can customize for different applications and customer needs using network slicing.


Fluctuation in activity of plasma peptidases has been noted as a concomitant of a wide variety of clinical disorders. These proteolytic enzymes exhibit enhanced activity in the plasma of man or experimental animals subjected to any severe tissue damage, and there is convincing evidence, discussed elsewhere (1, 2), that these enzymes gain entrance to the circulation from injured or destroyed cellular components. With healing (3) or clinical remission (4, 5), elevated plasma peptidase values return to the normal range, but the mechanisms involved in the removal of peptidase activity from the plasma have not been systematically investigated. The present study was undertaken in an attempt to determine the fate of these circulating peptidases.


QUALITY PROBLEM OR ISSUE
Inadequate observance of basic processes in patient care such as patient monitoring and documentation practices are potential impediments to the timely diagnoses and management of patients. These gaps exist in low resource settings such as Sierra Leone and can be attributed to a myriad of factors such as workforce and technology deficiencies.

INITIAL ASSESSMENT
In the study site, only 12.4% of four critical vital signs were documented in the pre-intervention period.

CHOICE OF SOLUTION
Implement a failure mode and effects analysis (FMEA) to improve documentation of four patient vital signs: temperature, blood pressure, pulse rate and respiratory rate.

IMPLEMENTATION
FMEA was implemented among a subpopulation of health workers who are involved in monitoring and documenting patient vital signs. Pre- and post-FMEA monitoring and documentation practice were compared with a control site.

EVALUATION
Participants identified a four-step process to monitoring and documenting vital signs, three categories of failure modes and four potential solutions. Based on 2100 patient days of documentation compliance data from 147 patients between July and November 2012, staff members at the study site were 1.79 times more likely to document all four patient vital signs in the post-implementation period (95% CI [1.35, 2.38]).

LESSONS LEARNED
FMEA is a feasible and effective strategy for improving quality and safety in an austere medical environment. Documentation compliance improved at the intervention facility. To evaluate the scalability and sustainability of this approach, programs targeting the development of these types of process improvement skills in local staff should be evaluated.


An improved process for the preparation of gemfibrozil, an antihypolipodimic drug substance, with an overall yield of 80% and ∼99.9% purity (including three chemical reactions) is reported. Formation and control of possible impurities are also described. Finally, gemfibrozil is isolated from water without any additional solvent purification.


The RNiO3 (R is rare earth) perovskites are famous for their metal to insulator transition (MIT). The temperature can be transformed and depends on the nature of the rare earth. The MIT in thin films and heterostructures of RNiO3 propose the chance to control the MIT as a function of thickness via strain using different substrates. We have reported the electrical transport properties of NdNiO3/NdGaO3, and NNO/NGO/STO structures. These structures were fabricated by pulsed laser deposition (PLD) method. The temperature of the MIT changes from 155K to 195 K. The electrical resistivity of the heterostructures undergoes MIT, depending on the thickness and deposition conditions. Thickness and deposition temperature were found to have a great impact on the electrical transport properties. The shift in TMI changes with thickness and it larger for thinner NdNiO3. The MIT of NNO thin films is responsive to strain and its partial relaxation creates an inhomogeneous strain field that broadens the MIT. This study may ...


Food justice, food cultures and people's engagement with healthy food production and consumption are key contemporary concerns, with a growing sustainable hospitality and tourism literature. Efforts range from narrowly focused initiatives, such as promoting organic produce and fair trade, to more holistic challenges to current systems through initiatives like the slow food and locavore movements, which may represent systemic alternatives. However, little analysis is available on how cafés and restaurants might become sites for experimentation in profitable and just sustainable hospitality, and places for sustainability engagement and education. Focusing on the evolution of a sustainable café in Adelaide, South Australia, this article explores how one entrepreneurial restaurateur uses his café to engage customers and community in a collaborative conversation about sustainable development, food, hospitality and tourism, helping transform our food culture and even lifeways. Our findings indicate the value of deep local embedding as a pathway to meaningful sustainability. The study offers insights into how hospitality and tourism can contribute to dialogues on alternative consumption which may offer visionary pathways to alternative futures. It also explores the role of pioneers in sustainable business and hospitality, their drivers and their views. A forthcoming global research initiative is discussed.


Medicare's 2013 physician-payment rule encourages a change in care delivery by providing for bundled payments to physicians for managing patients' transition back to the community after discharge from a hospital, rehabilitation facility, or skilled nursing facility.


Numerous studies speak in favour of the existent connection between the exposure to stressors, i.e. potentially stressful events and psychophysiological stress symptoms, as well as later psychopathology. However, although posttraumatic stress disorder has been defined by traumatic exposure as one of its criteria, in a series of repeated studies the correlations between measured exposure and clinical picture remain relatively low, as well as the rate of disorder development following trauma. Aims: The aim of the paper is to present the procedure of constructing of war stressors assessment questionnaire and its basic metric characteristics. The questionnaire covers a wide spectrum of stressors characteristic of war conflict in the former Yugoslavia to which the civilians were also exposed. Method: research was carried out on a sample of 238 subjects who had been exposed to war actions. In addition to the constructed questionnaire, the Impact of Event Scale - IES and Symptom Checklist-90-Revised version - SCL-90-R were applied. Results: By using Ward's cluster analysis method the eight categories of traumatic experience were obtained (active combat, witnessing of death or wounding, loss of organisational/military structure, war-related deprivation, injury, life in hostile surrounding, imprisonment/torture, combat exposure), and they were also verified by subsequent factor analysis. The questionnaire's subscales formed in this way have good metric characteristics. The obtained subscales had different correlations with the results from the IES and SCL-90-R, which were taken as measure of psychopathology. Conclusion: The constructed questionnaire covers different aspects of traumatic experience and has good metric characteristics. Its utility is reflected in the possibility of analysis of different aspects of the complex war experiences.


The efficient generation of entangled photons at telecom wavelength is crucial for the success of many quantum communication protocols and the development of fiber-based quantum networks. Entangled light can be generated by solid state quantum emitters with naturally low fine-structure splitting, such as highly symmetric InAs quantum dots (QDs) grown on (111)-oriented surfaces. Incorporating those QDs into optical cavities is crucial to achieve sufficient signal intensities for applications, but has so far shown major complications. In this work we present droplet epitaxy of telecom wavelength InAs QDs within an optical cavity on a vicinal (2° miscut) GaAs(111) A substrate. We show a remarkable enhancement of the photon extraction efficiency compared to previous reports together with a reduction of the density that facilitates the isolation of single spectral lines. Moreover, we characterize the exciton fine structure splitting and employ numerical simulations under the framework of the empirical pseudopotential and configuration interaction methods to study the impact of the miscut on the optical properties of the QDs. We demonstrate that the presence of the miscut steps influences the polarization of the neutral excitons and introduces a preferential orientation in the C 3v symmetry of the surface.


Large pre-trained transformers are on top of contemporary semantic segmentation benchmarks, but come with high computational cost and a lengthy training. To lift this constraint, we look at efficient semantic segmentation from a perspective of comprehensive knowledge distillation and consider to bridge the gap between multi-source knowledge extractions and transformer-specific patch embeddings. We put forward the Transformer-based Knowledge Distillation (TransKD) framework which learns compact student transformers by distilling both feature maps and patch embeddings of large teacher transformers, bypassing the long pre-training process and reducing the FLOPs by>85.0%. Specifically, we propose two fundamental and two optimization modules: (1) Cross Selective Fusion (CSF) enables knowledge transfer between cross-stage features via channel attention and feature map distillation within hierarchical transformers; (2) Patch Embedding Alignment (PEA) performs dimensional transformation within the patchifying process to facilitate the patch embedding distillation; (3) Global-Local Context Mixer (GL-Mixer) extracts both global and local information of a representative embedding; (4) Embedding Assistant (EA) acts as an embedding method to seamlessly bridge teacher and student models with the teacher's number of channels. Experiments on Cityscapes, ACDC, and NYUv2 datasets show that TransKD outperforms state-of-the-art distillation frameworks and rivals the time-consuming pre-training method.

The greenhouse effect is leading to global warming and destruction of the ecological environment. The conversion of carbon dioxide and methane greenhouse gases into valuable substances has attracted scientists' attentions. Dry reforming of methane (DRM) alleviates environmental problems and converts CO2 and CH4 into valuable chemical substances; however, due to the high energy input to break the strong chemical bonds in CO2 and CH4, non-thermal plasma (NTP) catalyzed DRM has been promising in activating CO2 at ambient conditions, thus greatly lowering the energy input; moreover, the synergistic effect of the catalyst and plasma improves the reaction efficiency. In this review, the recent developments of catalytic DRM in a dielectric barrier discharge (DBD) plasma reactor on Ni-based catalysts are summarized, including the concept, characteristics, generation, and types of NTP used for catalytic DRM and corresponding mechanisms, the synergy and performance of Ni-based catalysts with DBD plasma, the design of DBD reactor and process parameter optimization, and finally current challenges and future prospects are provided.

Maleic hydrazide (MH) partially suppressed flowering of onion (Allium cepa L. cv. Bawku) at 150 ppm and totally inhibited flowering at 1500 ppm. (2-Chloroethyl) trimethylammonium chloride (chlormequat) promoted flowering at 1000 - 4000 ppm.


The main aim of this paper is to investigate the corneal damage effects induced by mid-infrared optical parametric oscillator (OPO) radiation. Experiments were performed to determine the corneal damage thresholds of New Zealand white rabbit at the wavelength of 3743[Formula: see text]nm for exposure durations of 0.1[Formula: see text]s, 1.0[Formula: see text]s and 10.0[Formula: see text]s. Through slit-lamp biomicroscope and histopathology, corneal injury characteristics were revealed. The damage thresholds were 3.73[Formula: see text]J/cm2, 7.91[Formula: see text]J/cm2 and 31.1[Formula: see text]J/cm2, respectively, for exposure durations of 0.1[Formula: see text]s, 1.0[Formula: see text]s and 10.0[Formula: see text]s. The damage data was correlated by an empirical equation: Radiant exposure at the [Formula: see text] duration,[Formula: see text] where the units of radiant exposure and exposure duration were J/cm2 and second. At near-threshold level, corneal injuries at 1 h post-exposure mainly involved the epithelium, and the epithelium damages repaired at 24-h post-exposure. There are sufficient safety margins between the damage thresholds and the maximum permitted exposures from current international laser safety standard IEC 60825-1.


Abstract The Orion water-hardness electrode, while being used to measure magnesium ion activity in a series of calcium-free solutions, displayed some unanticipated changes in potential. As the overall potential change observed for one solution was 183 mV (equivalent to more than six orders of magnitude changes in magnesium-ion activity), several precautions are suggested which should be observed when using this electrode for specific purposes. In particular, it is recommended that the exchanger be pre-equilibrated with an appropriate solution if the electrode is to be used in restricted systems of known chemical composition.


Planning alternatives evaluation is often influenced by the evaluator's background knowledge and preferences, and its objectivity is hard to guarantee. A comprehensive evaluation method combining Geographic Information System (GIS) with system analysis technology is proposed in this paper. Using a land use issue in America as an example, GIS was combined with Fuzzy Logic, and the Analytic Network Process (ANP) method was used to evaluate three planning alternatives. The evaluation value of each qualitative index was obtained by Fuzzy Comprehensive Evaluation, and the quantitative index value was calculated by GIS algorithms. A weighted hypermatrix of ANP network was constructed to reveal the overall relative importance weight of alternatives. The results indicate that, in this case study, the factor weight rankings that influenced the selection of the land use alternative are Ecological factors (above 40%), socioeconomic factors (30%), Physical and Chemical factors (10–17%), and cumulative related factors (10%). In the long run, choices of planning alternatives will greatly affect the natural environment, the physical and chemical environment, and the social economy. The results indicate planners have to pay attention to a wide range of both qualitative and quantitative factors as much as possible in land use decisions. This study illustrates how the GIS-ANP method combine qualitative and quantitative factors in planning for a comprehensive analysis, thus improving the objectivity of evaluating land use planning alternatives and determining the importance of influencing factors. Future work aims to optimize the evaluation index system of planning, and measure index values in a more precise way.

Convention of the Law of the Sea, seabed lots are assigned to prospective mining companies in a manner that preserves the interests of developing countries in a simple two-player "cut and choose" game. The fundamental problem with any procedure is that it has to be applied to potential rather than actual conflicts. In every actual conflict, whenever the preferences are common knowledge, the conflicting parties are able to translate the procedure into expected outcomes and support or reject the procedure according to their evaluations of anticipated benefits. Thus, proposing a game is no different from proposing a specific outcome. More constructive applications are awaited whenever there is a need for legal regulation of potential conflicts. However, this requires that effective enforcement mechanisms be in place. To expect that, for instance, a procedure of fair division would have helped the Allies to divide postwar Germany, seems unrealistic. Brains and Taylor's book is a fine survey of procedures of fair division. It provides an invaluable reference for researchers, designers of fair procedures, as well as for teachers who want to discuss the games of fair division in their advanced undergraduate or graduate courses on distributive justice or conflict resolution.


In this study, hot gas is utilized to achieve rapid mold surface heating. Different inlet sizes (4mm, 6mm, 8mm) at the mold entrance was designed. Mold surface temperature was raised to above glass transition temperature within few seconds' heating prior to injection then mold is closed for melt injection. Heating speed can be as high as 40 oC/s. Hot gas heating was does eliminate the fiber floating marks of molded parts and achieving high surface quality. It was found that the gas inlet size can affect the heating speed and heating uniformity.


There are more than 6000 electronic cards for the instrumentation of the LHC cryogenics, housed in crates and distributed around the 27 km tunnel. Cards and crates will be exposed to a complex radiation field during the 10 years of LHC operation. Rad-tol COTS and rad-hard ASIC have been selected and individually qualified during the design phase of the cards. The test setup and the acquired data presented in this paper target the qualitative assessment of the compliance with the LHC radiation environment of an assembled system. It is carried out at the CNGS test facility which provides exposure to LHClike radiation field. I. THE CRYOGENIC INSTRUMENTATION ELECTRONICS The cryogenic instrumentation electronics are placed all around the LHC tunnel and in protected areas. Concerning the tunnel electronics, radiation was a main constraint since the beginning of the design phase. Space or military technologies were incompatible with the budget of the project and instead, Components Off The Shelf (COTS) were selected, qualified for operation under radiation and finally used [1, 2]. Adversely, the protected areas electronics have not been designed radiation-tolerant, as the radiation levels in the protected areas were quite underestimated. Many of the components of the protected areas electronics are the same as the tunnel ones; nevertheless, there are several components for which no information exists for their performance under radiation. The aim of the tests at the CNGS facility is to validate the complete systems (rather than individual components) in both cases: tunnel and protected areas electronics. The cryogenic instrumentation electronics (in the cases of tunnel and protected areas as well) are divided into conditioners, measuring temperature, pressure, liquid helium level and digital status, and into actuator channels, providing AC and DC power to the areas where helium needs to be heated-up. Figure 1 shows the architecture of the system, in the case of conditioner channels. A conditioner card holds two independent channels. Each channel has a front end ASIC taking measurements on a sensor. The resulting waveform is sent for digitization to the ADC. A 16 bit word is then sent to the FPGA for the first stage of processing and the formatting of the data provided to the communication card. Up to 15 channels may be interfaced with the same communication card, which implements the WorldFIP protocol and places the data on the Fieldbus. Figure 1: System architecture The system offers very high accuracy, due to its auto calibrating features [1]: For each measurement on a sensor, there is a measurement on a high precision reference resistance which permits the correction of the gain drifts. The polarity of the input of the amplifier is inverted so as to correct its offset. Finally, the excitation current is applied in both directions in order to compensate for the thermocouple effects, as well as any dc offsets of the wiring. II. RADIATION TOLERANCE STRATEGY The radiation, in the case of the LHC tunnel electronics, was faced in two main ways: an elaborate components selection and a set of mitigation techniques [1]. A. Components Selection Customized development of a radiation hard front end ASIC and of a linear voltage regulator for power supplies and references. Use of anti-fuse FPGAs. Selection of a Fieldbus agent (implementing the WorldFIP protocol) that uses signal transformers instead of optical insulators. Qualification for operation under radiation of all the components in dedicated facilities [2,3].


Many manufacturers have attempted to improve the productivity of their facilities without much success. The Japanese, on the other hand, have recently achieved significant improvements in productivity by implementing JIT. There are several reasons for the Japanese success. First, JIT adheres to well‐established concepts and methods of production and operations management. Second, JIT is a holistic approach to productivity that directs attention to all resources involved in producing a product, and to all factors affecting their utilization. Third, JIT avoids many obstacles to productivity, in addition to utilizing resources efficiently. Fourth, JIT focuses on shopfloor design and operations where resources are primarily affected. Manufacturing managers can learn several useful lessons for improving productivity from the Japanese experience.


Stress is the essential factor to cause surface oxide scale exfoliation to lose oxidation resistance for superalloys. In this paper, a new kind of experimental technique, rectangle wedge slice moment method, was studied to test in situ the real time oxide scale stress of ferro based superalloy GH2036 during high temperature oxidation. Having been oxidated for 10 hours at 800°C, the oxide scale stress σ versus time t was regressed to follow the power function σ=179.1745t0.0714. The scale stress goes up with oxidation time, but its gain decreases, reducing the exfoliation tendency and benefitting the protecting. New born oxides growing at the interface of matrix and scales generate the oxide scale stress. More oxides bring thicker scales, bigger stress and higher oxidation resistance.

Background : The hemangiossarcoma (HSA) is a malignant tumor originated from the alterations of vascular endothelial cells. As it has an aggressive behavior, it is indicated, as initial treatment, wide surgical excision, such as the exenteration, which results in the surgical removal of the ocular bulb and adjacent tissues. The referred technique has as a result a concave orbit and aesthetically unacceptable. Therefore, various materials, used as orbital implants, have been studied and used in several species. Thus, it was aimed to report the use of the polymethylmethacrylate (PMMA) to fill the orbital cavity after exenteration in a dog with conjunctival HSA. Case : A 10-year-old male Pitbull dog was assisted, with a clinical history of growth of a reddish tissue in the left eye, causing constant hemorrhage, with an evolution of two months. At ophthalmic examination of the left eye, in the temporal bulbar conjunctive was found a reddish neoformation, with an irregular surface, measuring approximately 4x2x2 cm. The biopsy and aspiration cytology of the neoformation, revealed cells that inferred that they were those of conjunctival HSA. The hemogram revealed normocytic anemia; the biochemical profile was with the standards of normality and no metastasis were found in the ultrasonography and X-ray. The treatment of choice was the exenteration. Initially, the palpebral borders were approximated using continuous simple suture wit monofilament nylon thread. An incision was made in the skin, along the orbital rim and then was performed a rhombus dissection of the conjunctive and all the extraocular muscles. Next, the eye globe, together with the neoplasia, soft tissues of the orbital cavity and third eyelid were removed. The PMMA was obtained from a mixture of the powder (polymer) and of the liquid (monomer) in the ratio of 1:1 in a sterile recipient, in order to obtain a liquid suspension. Still in its paste-like form, the PMMA was molded in the orbit itself without going beyond its limits, filling in. At the moment of the polymerization of the PMMA, the site was irrigated with cold sterile saline solution for the reduction of the temperature caused by the thermal reaction. For the closing of the conjunctive, a continuous simple suture was performed, using 910 4-0 polyglactin thread and, in the suture of the skin, simple interrupted stiches were used with 3-0 monofilament nylon thread. After the surgery, tramadol hydrochloride was administered at a dose of 2 mg/kg/SC and meloxicam at a dose of 0.1 mg/kg/SC.  In the post-operative phase, the animal was treated with ampicillin suspension at a dose of 20 mg/kg/TID/PO during 10 days; metronidazole at a dose of 15 mg/kg /BID/PO during 10 days and the application of 0.5% chloramphenicol ocular ointment, 10.000UI of retinyl acetate and 2.5% amino acids on the stiches, SID, until their removal. After nine months, the owner reported a satisfactory result in relation to the aesthetic aspect, denying the presence of any ocular alterations or discomfort of the animal. Discussion : The use of the PMMA implant proved to be an excellent alternative to fill the anophthalmic cavity after exenteration in a dog with conjunctival HSA, seen as it provided, most importantly, the maintenance of the orbital volume, granting an adequate aesthetic aspect, already established among some authors, without the presence of secretion, inflammation and local infection.  It is worth emphasizing that, despite the patient in question having been treat with a broad-spectrum antibiotic after the surgery, in other reports, the absence of local infection was associated to the high temperature that the PMMA reaches during the exothermic reaction in the polymerization stage. Furthermore, the referred implant is cost-effective, offers easy molding to the orbit and absence of extrusion. In light of this, it is therefore suggested that the referred implant is a pertinent alternative for use in similar cases.


PURPOSE
To verify the parameters and characteristics evaluated in printed complete denture bases and how they influence properties.

MATERIALS AND METHODS
This work was registered in Open Science Framework (osf.io/4um6v) and followed the PRISMA Extension for Scoping Reviews (PRISMA-ScR). A search of peer-reviewed articles published up to April 9, 2020 was performed on the PubMed, Lilacs, Cochrane Library, and Science Direct databases. The review question based on the population, concept, and context (PCC) was: What printing parameters and characteristics of complete denture bases can influence properties?

RESULTS
The database search resulted in 1,945 articles, and 1,390 article titles and abstracts were screened. A total of 17 articles were included. The summarized findings included: cleaning prostheses with alcohol after printing and a postcuring cycle influence biocompatibility and residual monomers; the printing angle influences physical/mechanical properties, microbial adhesion, and tissue adaptation; accuracy is influenced by layer thickness and the manufacturing technique, which also influences retention and tissue adaptation; the incorporation of antimicrobial agents influences physical/mechanical properties and antimicrobial activity; and the method of union between the base and the teeth influences mechanical strength.

CONCLUSION
Printed denture bases of 100-μm layer thickness showed good adaptation to tissues and accuracy, and it can be recommended that the prosthesis be cleaned in ethanol followed by postcuring for better biocompatibility. Nanoand microparticles can be added to provide antimicrobial activity and better resistance. Printing angle and mechanical properties must be better evaluated.


Wenchuan Earthquake,with high intensity and long period,caused masses of rolling rocks which derived from block stones of rock slopes divided by structure faces and big size corestones of soil slope.The block stones are projected with initial speeds.Their movements on slope surfaces are the combination of sliding,rolling and jumping.Based on the field investigation,this paper chooses two typical unsteady slopes caused by the earthquake to study movement characters of rolling rocks.Three findings are as follows.(1)The more the rolling rocks have equal three dimensions in length,width,and height,the farther the rock movement distance.But for platy rolling rocks,if their narrow side touchdown firstly,and collide elasticcally,they will jump at a high speed and move long-distance;(2)At the 1/2 height of slope surface or higher,rolling rock movement is sliding,rolling mainly.At the lower positions,it is jumping-rolling,jumping-sliding;(3)Big size(mass)rolling rocks mostly stay at the first touchdown or the wide gently areas at the slope toe areas.The way to consume energy is friction or collision disintegration,in which the ratio of platform block is 54% and trees(shrub) is 12%.By inversion,renew coefficient Rn and Tangentially renew coefficient Rt are obtained.For the bare bedrocks,Rn=0.3 and Rt=0.6.For the overlay,Rn=0.2and Rt=0.8.For moving rolling rocks,their bounce heights are between 0.49~3.10m.The ratio of the maximum rolling height and the farthest movement distance is 1/2.


Introduction. The "Heater-Blower-Room" thermal control system represents three different interconnected subsystems. It is necessary to study the transient characteristics of the heat exchange process, that is underway in the subsystems, including informative impulse responses, to stabilize the system operation. It is a non-parametric problem, and its solution requires identification algorithms.
Materials and methods. Mathematical models of the subsystems represent the Volterra integral equation of the first kind with an undetermined difference kernel, or an impulse response. An impulse response evaluation is a solution to this equation in respect of registered noisy input and output values. The problem is to evaluate unknown impulse responses for the subsystems where the output of one subsystem is the input of another one. This problem is ill-posed, and features of identification-focused experiments do not allow to apply computational methods of classical regularization algorithms. The co-authors propose two specific non-parametric identification algorithms where impulse responses are evaluated using stable first derivatives by means of smoothing cubic splines through the optimal smoothing parameter selection on the basis of the statistical optimality criterion.
Results. The co-authors solve inverse problems of impulse response identification and direct problems of heat flux reaction prediction. The research results demonstrate a high level of convergence between the evaluated data and observation findings. Both experimental and theoretical results represent the findings of the research performed by the co-authors.
Conclusions. The results have proven the efficiency of the algorithms proposed for the identification of solutions to the problems of complex technical systems.


Principal component analysis (PCA) and independent component analysis (ICA) are widely used to recognize faces, while relevance feedback (RF) is broadly taken to improve the performance of content-based image retrieving (CBIR) systems. Generally, variations due to illumination, camera geometry and pose have a great effect upon the result of face recognition. In this paper, above methods are combined to promote the detection and recognition rate of faces. Rather than performing PCA/ICA with holistic image, we take advantages of facial components in a facial image to reduce variations and matching complexity. Furthermore, when the component positions are well aligned, the variation due to geometrical factors can be compensated, and it results in further accuracy improvement. Finally, we propose relevance feedback to retrieve the defective in face detection and recognition.


Recent years have seen a growth in the use of language tests as measures of accountability within the education sector. In many countries, governmental institutions have promoted the involvement of teachers in language testing, providing training to boost the language assessment literacy (LAL) of teachers. This study aims to analyse the results of a large-scale effort to increase teachers' LAL within the context of public language education for adults in Spain by shedding light on the scale and nature of teacher LAL, the impact of training as perceived by teachers, and their self-perceived further needs. Results show that, similarly to other countries in which teacher LAL has been studied, training in assessment is strongly influenced by contextual factors. Moreover, teachers perceive that this training has an impact not only on assessment-related tasks, but on their general teaching practice. Lastly, the findings reveal a significant correlation between the contents of assessment training courses and the teachers' perception of further training needs. This could indicate that the more teachers learn about specific areas of language assessment, the more training in assessment they feel is needed, suggesting a gap in teachers' awareness of their own LAL that materialises once training is provided.


The resonant tunneling mechanism of the GaN based resonant tunneling diode (RTD) with an InGaN sub-quantum-well has been investigated by means of numerical simulation. At resonant-state, Electrons in the InGaN/InAlN/GaN/InAlN RTD tunnel from the emitter region through the aligned discrete energy levels in the InGaN sub-quantum-well and GaN main-quantum-well into the collector region. The implantation of the InGaN sub-quantum-well alters the dominant transport mechanism, increase the transmission coefficient and give rise to the peak current and peak-to-valley current ratio. We also demonstrate that the most pronounced negative-differential-resistance characteristic can be achieved by choosing appropriately the In composition of InxGa1−xN at around x = 0.06.


Abstract : This report pulled together two studies in different organizational settings--a university and a naval recruit center. The ANOVA analysis compared differences and consistencies by tasks between leader race, subordinate race, group composition, group size, and settings on number of output and intervening variables such as productivity of groups, duration of speech, satisfaction, self-esteem, Bales IPA behavior. Group composition and size had a significant effect through both studies on the self-esteem and satisfaction of black and white subordinates.


Mixture multimode optical field classical states propagating in N × N integrated directional couplers are analyzed by using the density matrix formalism in a N-dimensional optical space. These mutimode optical fields present a kind of generalized polarization and accordingly a definition of a multimode polarization degree is proposed. It is based on the distance measure between a mixture state and an unpolarized state in a N-dimensional optical space so that in the case N=2 the standard polarization degree is recovered. It is shown that directional couplers can reduce or increase remarkably the multimode polarization degree of a mixture state. Likewise a simple measurement technique, based on Y junctions, of this multimode polarization degree is proposed. Finally all the results can be formally extended to the special case of multimode single photon quantum states.


This article examines the case for Canadian trade bilateralism through the lens of the resource curse. As a favoured federal policy option for economic diversification, Canada's bilateral trade agreements have underperformed even as energy exports continue to rise. Given Canada's structural relationship to the global economy and the very low levels of diversification created by preferential trade agreements outside the NAFTA arrangement, there are few strong arguments for an intensification of Canadian bilateralism. However, the political reasons for bilateral trade agreements are better than the economic ones. Even though Canada's pattern of bilateral trade agreements to date does not suggest a coordinated attempt to unlock a specific region or strategic set of trading partners, a political stake in the current system pays dividends both in terms of diplomatic legitimacy as well as in the development of new templates for future agreements.


Summary.  Considerable evidence suggests that host genetic factor play an important role in the pathogenesis and clinical outcome of chronic hepatitis B virus (HBV) infection in several ethic groups. Association study was performed included 150 chronic HBV patients, 100 resolved hepatitis B and 150 healthy individuals with similar ethic background. Interestingly, human leucocyte antigen (HLA)‐DR13 show a strong association with the clearance of HBV [odds ratio (OR) = 0.04, 95% confidence interval (CI) = 0.00–0.26, corrected P‐value (Pc) = 0.0008] similar to reports from several ethic groups. TNF‐α promoter polymorphisms (−863, −308 and −238) were also analysed. Only −863 C allele was found to be significantly decreased in chronic HBV patients compared with healthy control (Pc = 0.03, OR = 0.54, 95% CI = 0.35–0.84 respectively). This −863C allele was not in linkage disequilibrium with HLA‐DR13 suggesting that other genetic markers linked with −863C might influence clearance of chronic HBV infection in Thai. When stratified chronic HBV patients into patients without hepatocellular carcinoma (HCC) and with HCC, the −863 A allele was significantly increased in the HCC group compared to healthy control (Pc = 0.003, OR = 2.61, 95% CI = 1.49–4.60). Haplotype analysis (−863/−308/−238) revealed that the homozygosity of the haplotype (CGG/CGG) was a protective marker for HCC (OR = 0.37, 95% CI = 0.17–0.79, Pc = 0.02). One can propose that carriers of −863A genotype are associated with increased levels of TNF‐α in the liver in response to HBV infection and induce hapatocyte damage that may finally lead to HCC development. Additional study is needed to validate these finding and to further explore the genetic pathogenesis of HBV infection.


This study discusses the design and implementation of blended learning activities at graduate level, in an effort to explore the potential of this approach to flexibly address student needs. The course was offered twice (in consecutive semesters), implementing varied blending proportions of traditional onsite sessions and web-based asynchronous learning activities. Research results indicate that there are at least three important factors strengthening the efficiency of the blended design, namely: a) introduction of blended activities that engage students in productive learning experiences; b) selection of media that fit to the characteristics of the learning activity; c) accomplishment of a balance between onsite and online activities so that teacher-student dialogue does not result in work overload with detrimental effects for learning. These factors are further determined as the 'cohesiveness', 'media suitability' and 'transactional distance' dimensions of a proposed theoretical construction aiming at modelling the transition process from fully onsite to blended design.

This paper presents the development of a simple user defined model for predicting the fuel saving benefits with brake energy recovery methods of a conventional vehicle. The need of detailed input to be described for the expensive commercial tools are avoided by the proposed simulator. The simulator developed in the paper is employed to predict fuel economy with Fig. 3 EMAS & Fig. 4 RMAS whose models are simulated and experimentally verified. With EMAS fuel saving benefits is found to be 1.4% while with RMAS it is 2.82% for the standard Fig. 6 NEDC considered in the present study.


The thesis mainly consists of two parts.In the first part, we study the quasi-invariant flow generated by the Stratonovich stochas-tic differential equation with BV drift coefficients in the Euclidean space. We generalizethe results of Ambrosio [Invent. Math. 158 (2004), 227{260] on the existence, uniquenessand stability of regular Lagrangian flows of ordinary differential equations to Stratonovichstochastic differential equations with BV drift coefficients. As an application of the sta-bility result, we construct an explicit solution to the corresponding stochastic transportequation in terms of the stochastic flow. The approximate differentiability of the flow isalso studied when the drift coefficient has some Sobolev regularity.In the second part, we generalize the DiPerna-Lions theory in the Euclidean space to thecomplete Riemannian manifold. We define the commutator on the complete Riemannianmanifold which is a probabilistic version of the one in the DiPerna-Lions theory, andestablish the commutator estimate by the probabilistic method. As a direct applicationof the commutator estimate, we investigate the uniqueness of solutions to the transportequation by the method of the renormalized solution. Following Ambrosio's method, weconstruct the DiPerna-Lions flow on the Riemannian manifold. In order to construct thediffusion process associated to an elliptic operator with irregular drift on the completeRiemannian manifold, we give some conditions which guarantee the strong completenessof the horizontal flow. Finally, we construct the diffusion process with the drift coefficienthaving only Sobolev regularity.Besides, we present a brief introduction of the classical theory on the ordinary differentialequation in the smooth case and the quasi-invariant flow of homeomorphisms under theOsgood condition before the first part; and we recall some basic tools and results whichare widely used throughout the whole thesis after the second part.


Micro determination of opium and strychnos alkaloids is of special interest to toxicologists, pharmacologists and forensic chemists. Among the methods that make use of the precipitation reactions for the quantitation of these alkaloids, radiometric titrations using labelled reagents possess many inherent advantages [1]. Suprisingly, despite their advantageous nature, radiometric titrations are relatively less explored for the determination of alkaloids. Some precipitants like 32P labelled phosphotungstic acid [2], phosphomolybdie acid [3] 110Ag labelled silver nitrate [4] and 131 I labelled iodo complexes of bismuth and mercury [5] have been reported in the literature for the radiometric determination of some alkaloids. But some of the above mentioned reagents require a rigid control of acidity for precipitation. 110Ag labelled silver nitrate reagent can be used only for the halide salts of the alkaloids and free based cannot be titrated with this reagent. Iodo complex of mercury requires a strict delinea...


Field experiments conducted for testing field efficacy of bioformulations for management of root knot nematode (Meloidogyne incognita) infecting tuberose (Polianthes tuberosa L.) cultivar ́Calcutta single' in West Bengal. Eight treatments evaluated for managing root knot nematode problem in tuberose and results indicated that Paecilomyces lilacinus, Trichoderma harzianum, neem cake, Pseudomonas fluorescens, Pochonia chlamydosporia were effective and economic for managing M. incognita in tuberose. Among the bioformulations, application of P. lilacinus @ 5kg enriched with FYM 5t/ha was found to be the most effective and economic for reduction of root knot nematode infestation, nematode population and enhancement of cut-flower yield of tuberose. The application of T. harzianum @ 5kg with FYM 5t/ha was also comparable to carbofuran @ 1 kg a.i./ha for root knot nematode management in tuberose. Further, the present study demonstrated efficacy of single application of bioformulations against M. incognita infecting tuberose


A modified biomaterial developed from Tympanotonus fuscata shell was characterized, for possible use as a pharmaceutical excipient. A 100 g quantity of pulverized periwinkle shell was digested in 166 ml of 2 M HCl, filtered and neutralized with 5 M NaOH. The precipitate obtained was washed severally with deionized water. Ortho-phosphoric acid was added drop wise to its thick aqueous suspension until a thick, dehydrated mass forms which was blended for 5 min and dried at 60 o C. It was classified with 250 μm sieve to obtain a modified biomaterial powder of periwinkle shell (MBPPS). This was tested for calcium and phosphate compound, solubility, pH, moisture absorption, acute toxicity, elemental content, drug compatibility, ash values, densities, flow parameters, etc. MBPPS was a compactable white powder, non-toxic (LD 50 >> 15,000 mg / kg body), tasteless, odourless, melting temperature, 190.8 o C, tested positive for calcium and phosphate compound and was compatible with a range of drugs. It was soluble in dilute HCl and HNO 3 but practically insoluble in cold water and organic solvents. Its 10 % w/v aqueous dispersion has pH of 7.57. Whereas, lead, silver, cadmium, nickel, vanadium, mercury or barium were not detected, iron and some heavy metals were detected, though their levels were within pharmacopoeial limit. MBPPS contained 2.28 ± 0.01 % moisture. It absorbed 6.98 ± 0.15, 9.08 ± 0.28 & 11.00 ± 0.87 % moisture in relative humidities of 96, 84, 75 and 52 % at 30 o C respectively. Total ash of 88.00 ± 1.30%, acid insoluble ash, 0.6 ± 0.24 % and water soluble ash, 0.5 ± 0.06 % were obtained. Considering the high yield of MBPPS, its non-toxicity, compatibility with a range of drugs, and hardness above 12 N of its compact, it may serve as a good material for direct compression of tablets especially for low dose drugs.

The visually effective luminous intensity of a short signal light has been defined hitherto by the blondel and rey method. A form factor is defined by Schmidt-Clausen which enables the simple comparison given by Blondel and Rey for a temporary right-angle luminous intensity distribution to be applied to any luminance intensity distribution. Analogue and digital measuring equipment is described which enables the effective luminous intensity of light in any form to be measured.

Although bungee jumping is a global phenomenon, Africa lags the world in terms of this particular sub-sector of adventure tourism, with commercial bungee jumping only taking place in Uganda, Zambia and South Africa. As South Africa's bungee sector is the most developed, research was undertaken in order to establish the nature of both the supply of, and demand for, this iconic form of hard adventure. The study found that bungee jumping stimulates local economic growth by generating substantial employment opportunities and spawning other adventure tourism activities and side businesses. Seasonality, combined with the global economic downturn has forced the operators to be entrepreneurially creative, in particular, to find ways of attracting more domestic tourists and day trippers. Thus, the financial base of bungee jumping in South Africa rests on domestic tourism. The demographic and socio-economic profile of the bungee jumpers is also presented, alongside factors which they identified as important with regards to the future growth of the industry. It is argued that a clean safety record and gold standard safety features could be adopted to expand the industry, as South Africa's commercial bungee jumping sector is globally competitive. However, the sector lacks official regulation and official safety standards, which is both a serious shortcoming and a hinderance to the development and growth of the sector.


As two main drivers of vegetation dynamics, climate variability and human activities greatly influence net primary productivity (NPP) variability by altering the hydrothermal conditions and biogeochemical cycles. Therefore, studying NPP variability and its drivers is crucial to understanding the patterns and mechanisms that sustain regional ecosystem structures and functions under ongoing climate variability and human activities. In this study, three indexes, namely the potential NPP (NPPp), actual NPP (NPPa), and human-induced NPP (NPPh), and their variability from 2000 to 2020 in the Guangdong–Hong Kong–Macao Greater Bay Area (GBA) were estimated and analyzed. Six main scenarios were generated based on change trends in the three indexes over the past 21 years, and the different relative impacts of climate variability and human activities on NPPa variability were quantitatively analyzed and identified. The results showed that the NPPp, NPPa, and NPPh had heterogeneous spatial distributions, and the average NPPp and NPPa values over the whole study area increased at rates of 3.63 and 6.94 gC·m−2·yr−1 from 2000 to 2020, respectively, while the NPPh decreased at a rate of −4.43 gC·m−2·yr−1. Climate variability and the combined effects of climate variability and human activities were the major driving factors of the NPPa increases, accounting for more than 72% of the total pixels, while the combined effects of the two factors caused the NPPa values to increase by 32–54% of the area in all cities expect Macao and across all vegetation ecosystems. Human activities often led to decreases in NPPa over more than 16% of the total pixels, and were mainly concentrated in the central cities of the GBA. The results can provide a reference for understanding NPP changes and can offer a theoretical basis for implementing ecosystem restoration, ecological construction, and conservation practices in the GBA.

Under the situation of increasing problems concerning with the environmental quality in forest land and the long-term productivity of forest,it was significant to develop and improve management strategies that maintain the function and protect the resources of soils.Changes of forest management strategies may lead to change in SOC quantity and quality.It was necessary to maintain a high SOC status for long-term land use due to the multiple beneficial effects of SOC on the soil nutrient states,structure and water holding capacity etc.The effects of different silvicultural practices on soil organic carbon were still poorly approached.Thus we performed the study on changes of soil organic carbon(SOC) in the Moso(Phyllostachys pubescens) stands among the long-term conversion of extensively managed and intensively managed in Fuyang County,Zhejiang province,where Moso were widely distributed.Bamboo stands of different management types,which were established in 1984,were designed to investigate the effects of intensive management on SOC.The results showed: total organic carbon(TOC),readily oxidation carbon(ROC),water soluble organic carbon(WSOC) and light fraction organic matter(LFOM) in 0—10cm soil layer were significantly decreased by 8.64%,14.11%,8.29% and 29.70%(0—20cm) respectively after intensive management.The vertical features of different soil organic carbon under two management types of bamboo stands were observed in decline trends with increasing of soil depths,while both of the decline scopes were different.The profile distribution of soil ROC and WSOC varied to some extent since intensive practice.These different fractions of labile organic carbon mentioned above were all interrelated,significantly or extremely significantly,and they also were well correlated with total N,hydrolysis N,available K,Ca,Mg(WSOC wasn′t significantly correlated with available P),while LFOM wasn′t significantly related to other soil nutrients except available Ca.Moreover after intensive management,availability of ROC,availability of WSOC and activity of carbon pool were decreased with significant level in part of soil layers.Therefore,to improve soil quality and achieve the goal of sustainable management of bamboo stands,a mixture of organic and inorganic manures with the proper ratio in bamboo stands should be applied under the conditions of intensive management,combined with ploughing,weeding,reasonable bamboo leaving and bamboo cutting,which could fulfill a high yield of bamboo shoot and bamboo culm,and maintain the ecological function of bamboo stands. The variation of results observed in soil C pool responded to different silvicultural methods in different studies may be due to variation in site types,original soil condition,timing and realization of forest managements,climatic factors,and/or interaction of some or all of these.However,this study along with the meta-analysis suggested that a categorical assumption of soil C loss under different forest management was unwarranted.Certainly,it was still needed to identify management methods that were most likely to cause or prevent SOC loss by further study.On the other hand,hydric soils may be much more sensitive to changes in temperature and moisture regimes as a result of silvicultural practices.Because the amount of the organic matter pool in mineral soils represents the potential to supply nitrogen,it is desirable to maintain organic matter in bamboo stands.


MIMO is now widely deployed in mobile devices, but existing exposure guidelines still focus on methodology for single antenna evaluation. MIMO enabled devices are required to comply with standards or internationally recognized guidelines for limiting human exposure to RF fields. Printed MIMO antennas capable of multiband operation which covers GSM 1800/1900, UMTS, WLAN, and several LTE frequency bands designed using CST studio. The flat phantom is used for testing the radiation absorption when the user places the mobile device close to the body, which is referred to as the "Body-worn mode". The head and hand phantoms are used in the case where a user performs a voice call with the phone, which is referred to as the "Talking Mode". SAR values calculated in these two modes, Stand-Alone SAR and MIMO SAR methods. Obtain SAR results are below the limit (1.6W/Kg).


In the paper we prove a factorization theorem for representations of fundamental groups of compact K\"{a}hler manifolds ({\em K\"{a}hler groups}) into solvable matrix groups. We apply this result to prove that the universal covering of a compact K\"{a}hler manifold with a residually solvable fundamental group is holomorphically convex.

This article is a sequel to that published in BSA 76. Our aim is to compare the structure of the Late Minoan tholos tomb with that of the five Mycenaean tombs already considered. It was possible to examine three tombs in Crete which are well preserved, namely, the tombs at Achladia and Stylos complete to the top of the vault, and the tomb at Apodoulou which has been partly restored. In the event Apodoulou proved unsuitable for analysis because of the amount of restoration. In date these Cretan vaulted tombs start later than the Mycenaean series and are generally placed in LM IIIA–B. That is to say, these tombs are later than the tholoi at Dimini and Marathon and approximately contemporary with the Tomb of the Genii and the Treasury of Atreus at Mycenae. It seems most probable that the technique of constructing tholos tombs was introduced to Crete from the mainland; it was argued in the earlier paper that the circular Mesara type tombs were not vaulted in the manner of the Mycenaean tholos tombs.


The CASE (Computer-Assisted Sentencing) system has been developed to help sentencers to choose an appropriate sentence to impose on a convicted offender. Primarily, the system is aimed at Magistrates' Courts. In England and Wales, by far the largest majority of sentencing is carried out by Magistrates, accounting for about 95 per cent of all sentences and over 80 per cent of sentences for more serious offences.
