Denis Bérubé (corresponding author) Mark Soucy Environmental Health Centre, Health Canada, Tunney's Pasture, 0800B3, Ottawa, Ontario, Canada, K1A 0L2 E-mail: email@example.com Aluminium speciation was characterized to examine the changes after filtration, in drinking water systems with low (#56mg l) and high (.100mg l) aluminium concentrations at plant outlet. The treatment chemicals were also examined, and only lime showed significant aluminium contamination. This contamination varied from 0.4 to 2.5mg mg and was largely water soluble (mean: 85%). The amounts of aluminium in lime added after filtration were equivalent to water concentrations ranging from 8.6 to 34mg l (mean: 17.5mg l). By using the less contaminated lime supply, the aluminium concentration contributions could have been four times lower (mean: 4.1mg l). When determining the concentration differences between the effluents of one filtering unit and plant outlet, the aluminium changes at the nine low-aluminium plants were associated with lime addition, and were mostly detected in soluble form. The changes at the eight highaluminium plants paralleled problems occurring at previous stages and were mostly attributed to variations occurring at additional filtering units. These situations prevented detection of other changes (e.g. post-precipitation). The monitoring of leachable particulate aluminium and of various parameters (pH, turbidity, Al–turbidity relationship) was also useful in differentiating particulate matter and demonstrating the effects of undesirable lime properties (dissolution delays, particulate residues).


PURPOSE/OBJECTIVE: Acid suppressing medications (proton pump inhibitors [PPI] and histamine-2 receptor antagonists [H2RA]) are used extensively in hospitalized term and preterm neonates despite limited efficacy data and increasing evidence for potential harm in this vulnerable population. The unfavorable risk-benefit ratio of PPI/H2RAs in newborns recently highlighted by the Choosing Wisely campaign prompted our team to develop a quality improvement initiative to reduce inappropriate use of these medications in our level III/IV NICU. Our specific …

In these days of stable growth of economy in Japan, proper operation and maintenance of existing structures which have been used for many years have become an important subject. Furthermore, making improvements in the study of this problem, it is pointed out that replacement plans of the structures based on life term prediction should be applied. However, as compared with operation and maintenance, life term prediction is much more difficult because of necessity of data base on material changes with the passage of time.The purpose of this paper is to describe the investigation results of life term prediction techniques focusing on hydropower steel structures. They are composed of simplified data acquisition and structural analysis, data base, expert system and others. Especially expert system plays an important role among them.


The technological scenarios that have arisen in Latin American universities have been substantially changing in recent months as a result of the international health emergency caused by COVID-19. The lockdown policy revealed the need to develop digital and informational skills to adapt to the environment and the demands of distance learning required for integral online education. In order to observe and systematize the transformation of the technological environment in academic libraries during these months, the recent situation was identified based on data analysis obtained from a questionnaire applied in Latin American countries. The results reported significant changes in the use of digital applications, services, user assistance and librarian training during the pandemic, as well as the libraries' mid-term commitments.


This project consisted of a review of the literature in subject areas related to driving stress, aging, and health. This document contains the following three sections: (1) A comprehensive review of the literature concerning the impact of driving on the health, behavior, and subjective well-being of drivers; (2) A comprehensive review of the literature on the cognitive and perceptual consequences of aging that is relevant to driving tasks and driving stress; and (3) The identification of personality and lifestyle dimensions which contribute to driver susceptibility to stress. Recommendations for research in each of these subject areas are suggested.


The design of a chronograph which will give a time trace subdivided into units and fractional units requires the association of a rotating system and a vibrating or time-keeping system. It a low-frequency vibrating system be employed, the rotating system, although keeping good average time, may show exaggerated errors in unit subdivisions due to acceleration and deceleration between periods of control. The Paper discusses the association of a high-frequency synchronous alternating-current motor with a high-frequency valve-maintained tuning-fork. It deals with the design of valve-maintained motors and condenser-tuned valve-maintained tuning-forks and gives expressions for the frequency of the maintained system for motors coupled to tuning-forks both without and with tuning condensers.


This paper presents results of an ecological study towards high-tide level near the mouth of the Dovey estuary, carried out in 1925–6. The area was treated as an extension of the sea floor, the only comparable work at that time being submarine. Petersen (1918) showed that on the bed of shallow seas the fauna could be grouped into "animal communities", whose constitution was determined by depth, distance from shore, shelter and salinity. Analysed with regard to distance from high-water mark, and degree of shelter, the fauna of this part of the estuary shows Petersen's Macoma community over most of the area, with a Corophium community at high tide in the more sheltered part. Davis (1925), in the North Sea, substituted "soil associations" as an alternative ecological unit, a certain grade of soil carrying its typical fauna wherever it might be found. The two groupings already found in the Dovey estuary clearly emerged as soil associations, after adoption of a reliable method for analysis of fine-grade soils. Up to the present, oceanographers have used sieves or elutriation for soil analysis. Up to the present, oceanographers have used sieves or elutriation for soil analysis. These methods are unsatisfactory for examinations of estuarine soils, with their large proportion of fine material.

The volcanic rocks of the Early Cretaceous Yingcheng Formation are the main reservoir rocks in the Qingshen gas field of the Songliao Basin.Reservoir space is classified as fissure and pore,the latter is premier and the former serves as main tunnels for fluid migration.There are 4 types of reservoir spaces,and the most common one is combined disoloved emposieu and micropore.By mercury penetration analyzing of volcanic samples,capillary pressure curves are on a scale from Ⅰ to Ⅴ.Volcanic breccias and breccias lava developing from volcanic conduit,vesicle rhyolith developing from intrafacies on top of effusion facies,and pyromeride or pearlite from inner zone intrafacies of intruded facies,are suggested to be the best reservoirs.Their sorting coefficient is from 0.3 to 2.6,coarse skewness,maximum pore throat's radius is 4.9 μm,thus being of better reservoir's physical properties.In all the ways,reservoir's pore structure of the region is featured by dominance of micropore throat,big proportion of pore and throat and wider distribution range.These reservoirs need commonly extensive fracture treatment so that commercial gas flows can be gained.

This essay argues that Wyndham Lewis' attempts to consolidate an identity for Vorticism against other contemporary avant-garde movements were riddled with anxiety and conflict. That anxiety and conflict pervade its creation suggests the tenuous nature of Vorticism beneath its facade of brash, satiric polemic, and they trouble the movement's self-definition as autonomous, authoritative and startlingly innovative. They also reveal that Lewis' Vorticist endeavors were more reactive than groundbreaking. At a fundamental level, the visual and textual innovations brought into play by Vorticism were exclusionary and too indebted to other avant-garde movements, on both national and international levels, to permit its solidification into an independent entity or its establishment of a preeminently English avant-garde as part of the cultural landscape. Notably, the revolutionary agendas of Italian Futurism, Bloomsbury formalism, French-based Cubism, and the British women's suffrage movement were more successfully publicized and longer lasting than Vorticism. Lewis' angst-ridden combativeness when confronted with competition can be traced in his interactions with contemporaries and in his work. It surfaces in his contributions to the two issues of his journal, Blast, his manifesto "The Code of a Herdsman," and in the 1918 version of his Vorticist novel, Tarr. In effect, Lewis' authorship of Vorticism can be read as an artistic experiment marked by a fear of assimilation, paradox and the compulsion to beat the competition.


Let d be a positive square-free number. Let Od be the ring of integers in Q(√ −d). The groups PSL(2, Od) are called collectively the Bianchi groups. The extended Bianchi group Bd is the maximal discrete extension of PSL(2, Od) in PSL(2, C). The group Bd acts by linear fractional transformations on the complex plane C. Let RBd be Bd with the generator θ, , adjoined. (RBd will be also called an extended Bianchi group (cf. [18])). A group is said to be reflective if it contains a Coxeter subgroup (i.e. a subgroup generated by reflections) of finite index. The groups RBd and their subgroups have been investigated in [3, 6, 13, 15, 16, 17, 18, 20, 21]. In 1892 Bianchi[3] proved that PGL(2, Od)⋊{θ} is reflective if d ≤ 19, d ╪ 14 or 17. Vinberg [18] proved that if the group RBd is reflective, then the orders of all elements of the ideal-class group of the field Q(√ −d) should divide 4. Shaiheev [16] proved that there are only finitely many reflective extended Bianchi groups and found all of them for d ≤ 30. Similar results are obtained for groups PGL(2, Od) ⋊ {θ} which, as Shvartsman [17] showed, are reflective only when d = 1, 2, 5, 6, 10, 13, 21, provided d = 1 or 2 (mod 4).


Background:Turcot's syndrome and Crohn's disease are not known to have common genetic, etiologic or pathogenic connection, however, both are associated with marked increased risk for developing colorectal cancer and, although uncommon, small bowel cancer. We present a pediatric patient diagnosed with both Crohn's Disease and Turcot's syndrome. This case is rare and challenging since surgical options must be considered and immunosuppressants/immunomodulators have potential to increase cancer risks. This open discussions about the potential association between Turcot's syndrome and Crohn's disease, as well as recommendations on surveillance programs. Methods:We present the case of a 13-year-old girl, with family history of Familial Adenomatous Polyposis (FAP), diagnosed with both Crohn's Disease and Turcot's syndrome. Endoscopic procedures, brain imaging and mutational analysis of the APC and MUTYH gene sequence were performed. Results:The patient was diagnosed with Crohn's disease based on colonic biopsies that revealed active colitis with a poorly formed granuloma and adjacent inflammatory exudate. Immunosuppressant and biologic therapy were started. She later developed headache, dysarthria and right-sided hemiparesis, 10 months after her initial diagnosis. Brain MRI showed large posterior fossa tumor with obstructive hydrocephalous, and biopsy was consistent with medulloblastoma. On a surveillance upper endoscopy and colonoscopy, multiple sessile polyps were noted in the duodenum and colon, which had histologic evidence of tubular adenoma. In the setting of the brain tumor with APC germline mutation, the patient had clinical characteristic of Turcot's syndrome. The diagnosis of both Crohn's Disease and Turcot's syndrome in the same patient complicates the surgical approach and it raises concerns regarding the potential increase cancer risks of common treatment options for Crohn's disease. Conclusions:A pediatric patient with both Turcot's syndrome and Crohn's Disease is a rare occurrence and both independently increase the risk of colorectal cancer. The management is particularly challenging since surgical options must be considered and immunosuppressants/immunomodulators have potential to increase cancer risks. It is unclear whether a stricter surveillance program is warranted. Further studies are necessary to determine the potential association between Turcot's syndrome and Crohn's disease and to identify the optimal management for these patients.


Objective To investigate the dietitian accouterment and influencing factors of kindergarten in Xuzhou. Methods A stratified cluster sampling investigation was conducted about dietitian accouterment and influencing factors in Xuzhou city and rural kindergarten. Results About 44. 2% of kindergartens had dietitians,city for 56. 8%,countryside for 13. 3% respectively,and of which 65. 2% were part-time. In nearly 3 years,the kindergarten which would equip dietitian with expectations on gender,education background and professional: female staff for 83. 7%,nutrition major for 81. 8%,degree of senior high school for 62. 8%,university for 34. 9%,and dietitian certification for 81. 8% respectively. Age of parents and kindergarten staff,the scale of kindergarten,and nutrition awareness of kindergarten staff and the children parents were influencing factors by Logistic regression analysis( P0. 05). Conclusion The rate of dietitian accouterment in Xuzhou kindergarten is not high. Whether the kindergarten accounting dietitians depends on the kindergarten scale,age and nutrition awareness of parents and kindergarten staff.


Objective To study the impact of nutritional guidance on fetal macrosomia,maternal complications and cesarean section rates.Methods A total of 5 546 expectant mothers in our hospital from July 2010 to July 2012 were selected as observation group,who received nutritional guidance,intervention and follow-up visit.And meanwhile,a total of 2 848 hospitalized expectant mothers were selected as control group who did not receive nutritional guidance but regular check-ups during pregnancy.Both groups were compared for fetal macrosomia,maternal complications and cesarean section rates.Results There were 333 cases of fetal macrosomia in observation group,accounting for 6.0% and 341 cases in control group,12.0%,which showed significant difference(χ2= 10.412,P 0.05).Common factors affecting cesarean section rates can be maternal,fetal,social and cephalopelvic.Nutritional guidance during pregnancy can reduce maternal complications and the rate of cesarean section.Significant difference was found between the two groups(all P 0.05).Conclusions Nutritional guidance during pregnancy can significantly reduce cesarean section rates.

In Ecuador there are very few non-profit organizations that actually invest in advertising, which limits their ability to accomplish their goals. SOLCA being one of them, counts with limited communication actions that keep people and business from investing in their cause. These issues ad up with the fact that each year there is an increasing amount of patients and governmental changes that limits the budget of the hospital affecting their everyday work. Therefore there is the need to develop a 3.0 communication strategy that will reach a target that might be interested in getting involved with the cause while informing ´people about cancer. The goal is to raise funds for the hospital by touching the sensitive fibers of people making them wonder about their own reality. The strategy will involve online actions, print material and below the line activities that reflect the target's behavior and the limited budget of the hospital. This will guarantee an optimization while reaching a lot of people that translates to a maximum exposure of the message. The result will be an strategic communication plan for SOLCA with the possibility of
application in similar foundations, hospitals or institutions, that achieves the much needed long term engagement with the audiences and enterprises interested in making a difference in a win/win scenario for both parts involved.

Background Early wheezing in infants is a potential risk factor for persistence of asthma into adulthood. Moreover, a personal or familial history of atopy are risk factors associated with persistence of pre‐existing wheezing during childhood. However, their relative importance remains unclear.


A case of olfactory neuroblastoma is reported. A 74-year-old man visited our hospital exhibiting left nasal obstruction and bleeding in May 1997. An examination revealed a large tumor in his left nasal cavity; its surface was smooth and it bled easily. The patient did not have any visual acuity difficulties and the cervical lymph nodes were not swollen. A CT scan revealed a large tumor in his left nasal cavity and maxillary sinus which did not extend into the cranial space or eye socket. There were no bone defects. The patient underwent surgery for an olfactory neuroblastoma in June 1997. Based on the pathological findings, we made a diagnosis of olfactory neuroblastoma. The patient was treated with radiation therapy after surgical therapy. 45 Gy radiation therapy was added. The patient was followed up for 1 year and 6 months. In January 1999, there was local tumor reccurence and the tumor invaded his brain. Unfortunately, he died soon after from this local recurrence of his brain tumor in June 1999.


User engagement and support is getting increasing attention in the world of institutional repositories as user-driven improvements are becoming the norm. As the Los Alamos National Laboratory Research Library prepared for an interface overhaul intended to modernize current online tools, we developed a pipeline to track and analyze user feedback. We focused our efforts on emails specific to one tool sent to the helpdesk, from its launch in March 2012 to November 2018. We analyzed both email volume and email contents and found that while email volume is stable over time, contents vary in correlation to changes in tool workflows, capabilities, and policies dictating tool use. Our developed methods offer insights into user behavior and guidance for future tool development.

The problems of deriving temperature structure for thermal hard X-ray sources and electron spectra for nonthermal sources, from their bremsstrahlung continuum spectra, are briefly reviewed and the dangers of model-fitting are reiterated. A more satisfactory approach is developed in terms of the evaluation of integral moments of the distribution function.Using thermal analysis of the impulsive solar hard X-ray burst of 1970 March 1 as an illustration, the integral moment method is shown to give a rapid assessment of the real information content of a bremsstrahlung spectrum. In particular it is shown that due to limitations of bandwidth and, to a lesser extent, of spectral resolution, current hard X-ray spectrometry alone is incapable of distinguishing isothermal, multithermal, and nonthermal sources. Criteria are established for the spectrometer needed to define a thermal source distribution to within some specified accuracy.


In the last decade, the advancement of endoscopic and minimally invasive surgery has had a significant impact on patients and surgeons in various surgical fields. But in heart surgery the design of telemanipulators did not leverage endoscopic procedures. The focus is on building an experimental system for endoscopic and minimally invasive heart surgery which provides force feedback. In addition automating endoscopic surgical skills like knot-tying are implemented.


This paper discusses the real causes of the virtual water flow pattern with different angles: the endowment and optimizing allocation of resources,economic value,natural attributes and consumption structure. The relative efficiency of agricultural resources utilization has been measured in 2000 and 2007 in different regions of China by the revised data envelopment analysis model ( DEA) ,which shows that the efficiency has great potential to improve and the economic growth of China will not be a threat to food security in itself and the world. Then,we analyze the applicability of"virtual water strategy". Some suggestions about the security of national food and water resource are presented simultaneously.


The small sized yellow-bellied toad inhabits small temporary water bodies. These puddles are used by this species in both open landscapes and closed forested habitats. The thermal characteristics of these puddles in the open and closed habitat types showed considerable difference. In laboratory conditions the toad selected a narrow and low preferred temperature range (20.5-23.3°C). The measured voluntary thermal maximum (VTMaxwater) and critical thermal maximum (CTMax) was 35.9 ± 1.3°C, and 38.3 ± 0.5°C respectively. In the field, the toads using the surface water layer were thermoconformers irrespective of the actual thermal environment. The high VTMaxwater and CTMax presumably permit the use of such a thermoregulatory strategy.


Abstract 4749 Background: That pediatric, adolescent and young adult cancers have become compatible with long term survivorship in the majority of cases has meant a growing emphasis on an understanding of the late effects of treatment. Among the barriers to successful health self-management in the context of transition of care from pediatricians to internists is the challenge of finding adult health care providers in the community who are comfortable caring for patients in this age group. We have developed a curriculum relating to different aspects of AYA survivorship for oncology and primary health care trainees who may come across AYA cancer survivors in the course of usual practice. Focus groups were used to refine the modules before the current application. Aim: To improve provider knowledge of AYA survivorship issues and management in a university setting. Methods: Using a combination of review articles, original research, and published guidelines for cancer survivorship, 8 teaching modules (power point presentations of 8–15 slides each) were developed: health care self-management; bone health; cardiac late effects; fertility late effects; neurocognitive late effects; psychosocial late effects; pulmonary late effects; and second malignancies. Modules were refined with the use of provider focus groups. These recently have been made available to trainees at UNC: (pediatrics [P], medicine-pediatrics [MP], medicine [M], medical hematology oncology [MHO], pediatric hematology oncology [PHO], and nurse practitioner students [NP]) in hard copy and on departmental websites. Computerized pre- and post-tests were developed for each module to assess content acquisition and will be required of the ~6 trainees/month rotating through the Survivors Clinics or on inpatient or outpatient services. At the end of each module, participants also are being asked, using a 3 point scale (agree [3], neutral [2], disagree [1]) if they feel the sessions gave them increased confidence in following AYA survivors. Participants also will be given the opportunity to critique the modules. Results: Preliminary results will not be available until December. However, enthusiasm among the target audience during the first 2 months of this program has been strong. Conclusion: Short teaching modules can be developed to engage trainees in AYA late effects issues. Ongoing work is being done to assess the effectiveness and usefulness of the modules for providers at UNC who care for adolescent and young adult cancer survivors. We anticipate that this approach will be expanded to our outreach practices. Parallel modules are in development for AYA survivors and their families. *With support from a 2009 ASH Alternative Training Pathway Grant, T. Shea, PI.

The gas plant for the proposed Niglintgak Anchor Field is expected to be assembled on a barge, towed to the Mackenzie River Delta and ballasted down onto the bottom of an excavation advanced into the side of a river channel. In order to place the barge onto the excavation, ballast tanks inside the barge will be filled with water pumped from the river. The gap between the barge and side slopes of the excavation will then be backfilled with excavated materials. The ballast water inside the unheated barge may convey thermal impact to the existing permafrost below the barge. During 2006 to 2008, field tests were initiated to investigate the water freezing progression and growth of hydrostatic pressure in the test tank as well as the dynamics of permafrost temperature under the tank. Based on results of the field tests, 3- dimensional geothermal analyses for the gas plant barge were carried out to predict the development and seasonal melt of ice within the ballast tanks and assess permafrost conditions under the barge over the operational life of the structure. Various scenarios of the ballast water freezing were considered.


Given an endogenous/confounded binary treatment D, a response Y with its potential versions (Y0, Y1) and covariates X, finding the treatment effect is difficult if Y is not continuous, even when a binary instrumental variable (IV) Z is available. We show that, for any form of Y (continuous, binary, mixed,…), there exists a decomposition Y = μ0(X) + μ1(X)D + error with E(error|Z,X) = 0, where μ1(X)≡E(Y1‐Y0|complier,X) and 'compliers' are those who get treated if and only if Z = 1. First, using the decomposition, instrumental variable estimator (IVE) is applicable with polynomial approximations for μ0(X) and μ1(X) to obtain a linear model for Y. Second, better yet, an 'instrumental residual estimator (IRE)' with Z−E(Z|X) as an IV for D can be applied, and IRE is consistent for the 'E(Z|X)‐overlap' weighted average of μ1(X), which becomes E(Y1‐Y0|complier) for randomized Z. Third, going further, a 'weighted IRE' can be done which is consistent for E{μ1(X)}. Empirical analyses as well as a simulation study are provided to illustrate our approaches.


We report on mesoscopic Hall sensors allowing accurate magnetization studies of submicron or nanometer-sized samples over a wide temperature range. Even at 300 K, the probes can reliably resolve local changes in dc field of ≈ 1 G with spatial resolution of ≈ 1 μm, which corresponds to a flux sensitivity of less than 0.1 ϕ0 (ϕ0=h/e is a flux quantum). The resolution increases 100 times at temperatures below 80 K. The capabilities of new micromagnetometers are demonstrated by measuring nm-scale movements of individual domain walls in a ferromagnet.


Electrochemically-active conducting polymers (ECP) swell or shrink in response to ion and solvent incorporation or ejection as a result of electrochemical reaction of the polymer. As a consequence, they are, in principle, attractive materials to consider for inducing fluid motion of electrolytes in microfluidic systems. When anodic potential is applied to an electrode attached to one end of ECP strip, the oxidation process starts from the electrode and proceeds along the polymer, propagating as a wave. This wave is driven as a consequence of the electrochemical reactions and would be coupled to a propagating front of compositional change. This property of the ECP can be used to design pumps and mixers for microfluidic systems. We in this paper have modeled the oxidation wave propagation and its influence in pumping and mixing of electrolytes in a micro-channel using Comsol 3.5a. The swelling and wave propagation of the conducting polymer was modeled using the moving mesh method (ALE) and we here have solved the coupled convectiondiffusion equation and Navier-Stokes equation for finding the velocity and concentration changes in the electrolyte.


This paper discusses the design, development, and use of a performance monitoring tool for Distributed Interactive Simulation (DIS). DIS has proved to be a cost effective technique for studying and understanding complex real-world systems. A typical DIS environment consists of hundreds of simulations distributed on both local and wide area networks. As the size and complexity of DIS applications increase so do the demands on the hardware and software resources that provide simulation services, causing performance bottlenecks that limit the effectiveness of DIS. The performance monitor described in this paper detects, collects, and displays high-level performance metrics that describe behavior of the physical and logical resources and services used in the design and implementation of DIS. Dynamic and static analysis of the performance information provides feedback on the execution of the simulation. This feedback can provide meaningful information as a guide in making decisions about the configuration and control of the available hardware and software resources for DIS exercises; the goal is to provide information needed by exercise planners and managers rather than the program developers. This information can also be used to support DIS modeling requirements and design. Performance monitoring can affect the run-time behavior of DIS so alternative implementations must be considered to achieve a balance in the volume of performance data collected, the granularity of measurement, and the intrusiveness of the instrumentation code required to measure DIS performance. Using the monitoring system during DIS exercises has demonstrated the utility of a tool that provides high-level performance information to support persons making inferences about dynamic system and simulation behavior.

The paper proposes a parallel algorithm for solving the Graph-Subgraph Isomorphism Problem and makes an experimental study of its efficiency. The problem is one of the most famous NP-complete problems. Its solution may be required when solving many practical problems associated with the study of complex structures. We solve the problem in a formulation that requires finding all existing isomorphic substitutions or proving their absence. In view of the high complexity of the problem, it is natural to want to speed up its solution by parallelizing the algorithm.We used the RPM ParLib library, developed by the author, as the main tool to program the algorithm. This library allows us to develop effective applications for parallel computing on a local network under the control of the runtime environment .NET Framework. Thanks to this library, applications have the ability to generate parallel branches of computation directly during program execution and dynamically redistribute work between computing modules. Any language with support of the .NET Framework can be used as a programming language in conjunction with this library. For the numerical experiment, an open database from the Internet was used, which was specially developed to study algorithms for searching for isomorphic substitutions. Also, the author has developed a special application in C# for generating additional sets of initial data with specified characteristics. The aim of the experiment was to study the speedup achieved due to the recursively parallel organization of computations. The paper provides a detailed description of the proposed algorithm, as well as the results obtained during the experiment.

Objective:To investigate the effects of MMPs on the proliferation of hepatocellular carcinoma under the influence of HBV and to review the relationship between MMPs and tumor invasion and metastasis,by testing the expressions of MMP-2 and MMP-9 in the cells of HepG2 and HepG2.2.15 and the speed rate of the cells in vitro.Methods:HepG2 cells and transfected HBV expression plasmid HepG2.2.15 cells were selected to test the expressions of MMP-2 and MMP-9 with immunohistochemical method,and the cell proliferation was detected with MTT method to observe some biologic activities of the cells.Results:MTT and the cell growth curve showed that the growth rate of HepG2 was faster than that of HepG2.2.15.Immunohistochemical detection showed that the expressions of MMP-9 in HepG2 cells was higher than that in HepG2.2.15,however,there was no significant difference of the expressions of MMP-2 between the two kinds of cells.Conclusion:It is revealed that HBV has some inhibitory action to the growth and proliferation of hepatocellular carcinoma by testing the difference of growth tendency between the cells of HepG2 and HepG2.2.15 in the cell line of hepatocellular carcinoma.HBV can restrain the expression of MMP-9 in the cells of hepatocellular carcinoma so as to influence the ability of tumor invasion and metastasis indirectly.


The paper considers the development of a method for positioning a mobile device using a sensor network of BLE-beacons, the approximation of RSSI values and artificial neural networks. The aim of the work is to develop a method for positioning small-scale industrial mechanization equipment for building unmanned systems for product movement tracking. The work is divided into four main parts: data synthesis, signal filtering, selection of BLE beacons, translation of the RSSI values into a distance, and multilateration. A simplified Kalman filter is proposed for filtering the input signal to suppress Gaussian noise. A description of two approaches to translating the RSSI value into a distance is given: an exponential approximation function with a coefficient of determination of 0.6994 and an artificial feedforward neural network. A comparison of the results of these approaches is carried out on several test samples: a training one, a test sample at a known distance (0–50 meters) and a test sample at an unknown distance (60–100 meters). The artificial neural network is shown to perform better in all experiments, except for the test sample at a known distance (0–50 meters), for which the r.m.s. error is higher by 0.02 m 2 than that for the approximation function, which can be neglected. An algorithm for positioning a mobile device based on the multilateration method is proposed. Experimental studies of the developed method have shown that the positioning error does not exceed 0.9 meters in a 5×5.5 m room under monitoring. The positioning accuracy of a mobile device using the proposed method in the experiment is 40.9 % higher. Experimental studies are also conducted in a 58.4×4.5 m room, showing more accurate results compared to similar studies.


On September 5,2012,a disease outbreak was occurred at a tilapia farm in Liuzhou,Guangxi. A γ-hemolytic gram-positive streptococcus was isolated from brain of infected tilapia. The isolate was identified as rare Streptococcus agalactiae by biochemical assays,PCR identify and 16 S rDNA analysis. The strain was γ-hemolytic and negative in CAMP test which showed it was different from normal Streptococcus agalactia strains. The isolate exhibited high virulence to tilapia by experimental infection. Drug sensitivity experiment showed that it was resistant to norfloxacin,polymyxin B,cotrimoxazole and sensitive to 17 types of antibiotics such as penicillin G,et al.


About 20–30% of patients with chronic plaque psoriasis have severe forms of the disease and require systemic treatment. The long‐term use of conventional systemic therapies is limited by toxicity, and many patients are resistant to these treatments. New biological agents, such as efalizumab and infliximab, offer a more targeted approach than conventional therapies and are more suitable for long‐term, continuous treatment. At our hospital, we started treating patients with efalizumab in 2003 as part of a clinical trial programme and report here our experiences with this agent in 31 patients we have treated over the last 3 years. Here we share our standard procedures for patient selection, screening and treatment initiation, and report the efficacy and safety of efalizumab in our patients. Several case studies are presented to illustrate specific points of interest, such as the use of efalizumab in unstable psoriasis and management of arthropathy events. Finally, we suggest a number of approaches that may help to maximize the chances of long‐term success in patients receiving efalizumab. In our hands, efalizumab has proven to be an effective therapy in the majority of patients (> 70%). The majority of these patients move to continuous efalizumab therapy (77%), the longest duration of which is currently 18 months. The main advantage of efalizumab over tumour necrosis factor‐blockers is the lower risk of serious side‐effects. By devising and disseminating effective strategies for the management of patients receiving efalizumab therapy, we hope this treatment will offer patients a truly continuous, long‐term solution to their disease.


PROBLEM
Because of the negative impact on health of drug and alcohol use, this study examined adolescent needs and substance use.

METHODS
Subjects (N = 191) were adolescents aged 14 to 19 in a rural and an urban high school. A modified version of the Need Subscale from the Addiction Research Center Maturation Scale measured a feeling of satisfaction related to meeting basic needs, and an investigator's prepared questionnaire elicited current use of alcohol, nicotine, and marijuana.

FINDINGS
Individuals with feelings of unmet needs were more likely to be current drinkers. Rural/urban residence was not a significant predictor in a multivariate analysis, but religiosity was.

CONCLUSIONS
A feeling of unmet needs seems to be an important factor in adolescent substance use.


Purpose: This study investigated the quality characteristics and antioxidant effects of Yakju added with rose, camellia, or cockscomb flower during fermentation. Methods: The quality characteristics and antioxidant effects were estimated including pH, amino acidity, total acid, ethanol content, color value, sensory test, electric donating ability, nitrite-scavenging ability, and ferrous ion chelating effect. Results: The pH values of Yakjus added with rose, camellia, or cockscomb flower were decreased after 2 days of fermentation and then increased after 4 days of fermentation, with final pH ranging from 4.15 to 4.27. Total acid content and amino acidity were increased during fermentation. The ethanol content in Yakjus fermented with rose, camellia, or cockscomb flower was rapidly increased after 2 days of fermentation, reaching the maximum content of 19.1% after 8 days of fermentation. In color evaluation, the L values of Yakjus added with rose, camellia, or cockscomb flower did not changes during fermentation, whereas values of a and b were increased. Total phenolic compound contents in Yakjus added with rose, camellia, or cockscomb flower were 0.67, 0.59, and 0.52 mg/mL, respectively. Total flavonoid contents in Yakjus added with rose, camellia, or cockscomb flower were 0.20, 0.09, and 0.26 mg/mL, respectively. In sensory test, the overall acceptability of Yakjus added with cockscomb flower was higher than that of Yakju added with rose or camellia flower. However, the difference was not statistically significant (p<0.05). Electron donating ability and nitrite-scavenging abilities were the highest in Yakjus added with rose flower, whereas ferrous ion chelating effect was the highest in Yakjus added with cockscomb flower. Conclusion: These results indicated that Yakjus added with rose, camellia, or cockscomb flower might have valuable functional properties due to their antioxidant effects.


A theory of the neutron scattering intensity from an imperfect vortex lattice in type-II superconductors is developed, which predicts that flux pinning leads not only to a broadening of the Bragg reflections, but also to a finite scattering intensity for wave vectors within the first Brillouin zone. At sufficiently high fields, the small-angle scattering intensity is predicted to exceed that of the Bragg reflections. According to this theory, if the incident beam is chosen parallel to the applied field, shear and tilt strains in the vortex lattice, and thus the most important intrinsic defects, give no contribution to small-angle scattering, and the measured intensity is due almost entirely to the strains caused by pinning forces. Small-angle neutron scattering experiments are thus capable of yielding insight into elementary pinning interactions beyond that obtainable from volume pinning force measurements, which must be interpreted by means of still unsatisfactory statistical summation theories.


We developed a quantum field theoretical description for the surface states of three-dimensional topological insulators. Within the relativistic quantum field theory formulation, we investigated the dynamics of low-lying surface states in an applied transverse magnetic field. We argued that, by taking into account quantum fluctuations, in three-dimensional topological insulators there is dynamical generation of a gap by a rearrangement of the Dirac sea. By comparing with available experimental data we found that our theoretical results allowed a consistent and coherent description of the Landau level spectrum of the surface low-lying excitations. Finally, we showed that the recently detected zero-Hall plateau at the charge neutral point could be accounted for by chiral edge states residing at the magnetic domain boundaries between the top and bottom surfaces of the three-dimensional topological insulator.


To evaluate the clinical effect and safety of Ertianyou Balm in the treatment of cold by comparing with Essential Balm.280 patients were selected and divided into two groups randomly, 210 cases in the test group and 70 cases in the control group. Ertianyou Balm was applied to smear on the frontal eminence, philter, temple, Fengchi(GB20), and the center of the eyebrows when necessary. The course of therapy was 3 days. Every day before and after the application, the subjects' symptoms were observed and evaluated in the whole course of treatment. Moreover, the same performance was conducted when the period was over.Ertianyou Balm can competently control the main symptoms of the initial stage, such as headache, stuffy nose, snivel, sneezing and their rate of cure was 12 40%,23 3%,14 85%,21 9% respectively 1 hour after the application. The rate of significant effect was 15 2%, and the total rate of effect was 59 5%, The cure rate increased to 85 24% and 95 24% respectively 3 days after the application. It didn't show significantly statistic differences between Ertianyou Balm and Essential, and no side effects occurred. [Conclusion]Ertianyou Balm was a markedly effective, safe, convenient drug in preventing and curing cold.


A pilot satellite experiment is described which would employ shuttle imaging radar (SIR) to determine the applicability of imaging radar for the description of sea ice type and movement. The experimental objectives, design, and anticipated results are discussed. The results are expected to constitute an important contribution to the understanding of the role of sea ice in air-sea interactions in polar regions. It is proposed that shuttle photography, thematic mapper imagery, and SIR data be utilized in this remote sensing project.

Photographic images reduce the three dimensional world they are capturing into a 2D plane. There are a variety of applications in which it would be useful to determine the original distance to objects in the scene from the focal plane of the image. Such applications include robotic vision systems, 3D scene reconstruction, and surveying. Recent efforts to provide automatic analysis of scene depth using a single image have proved quite successful[4], however, ambiguities still arise in complex scenes, and non-general assumptions of the environment are made in ensure the best response of the algorithms. In contrast to traditional cameras, recent work has made use of a light field camera, which captures the 4D light field of the scene. The details of how this is done are described below. By using the extra information in the light field, we hope to provide a more general implementation of a depth map learning algorithm, which requires fewer parameters to train, and which will work in a variety of environments.


On August 5, 2014, after 29 days of fighting, Israel and Hamas accepted an Egyptian proposal for a 72-hour unconditional cease-fire. The cease-fire was meant to provide a calmer environment for direct and indirect talks on stabilizing the relations between Israel and Gaza. Fire was renewed after the agreed three days of quiet did not produce a breakthrough but another ceasefire went into effect on the morning of August 11, allowing the renewal of negotiations in Cairo on the terms of a broader and more enduring understanding. This fluid phase in the process might continue for some time before such an understanding is reached. This Brief is an attempt to sketch the basic requirements for transforming any cease-fire the parties may agree on to more stable relations between Gaza and Israel, and between Israelis and Palestinians more broadly.


include virtual reality and augmented reality, artificial intelligence, and modeling and scheduling of computer-integrated systems. Dr. Tang is very active in adapting and developing pedagogical methods and materials to enhance engineering education. Her most recent educational research includes the collaboration with Tennessee State University and local high schools to infuse cyber-infrastructure learning experience into the pre-engineering and technology-based classrooms, the collaboration with community colleges to develop interactive games in empowering students with engineering literacy and problem-solving, the integration of system-on-chip concepts across two year Engineering Science and four year ECE curricula, and the implementation of an educational innovation that demonstrates science and engineering principles using an aquarium. Her work has resulted in over 100 journal and conference papers and book chapters. Abstract Modern classroom settings require integrating many students of varying backgrounds and varying levels of classroom performance into the same educational process. Ideally, each student should receive personalized support that is tailored to their specific learning style. However, with limited resources and time available to educators and teaching facilities, personalized support is often infeasible. To address this issue, this project focuses on a learning system that uses artificially intelligent agents to provide students with personalized feedback and support. To further engage students, the system is built on top of an existing narrative game environment called Gridlock. Gridlock provides students with a narrative game experience that focuses on creating a traffic light controller to teach students the basics of sequential digital logic design, a core component in both Computer Engineering and Computer Sciences. Gridlock was chosen as it already implements several meta-cognitive strategies designed to promote student learning and student self-reflection, thus giving a solid foundation to build the learning support system on top of. This paper reports preliminary results from early testing and continued development of the Gridlock system. In testing the game system, students in Introduction to Digital Systems courses and Computer Architecture courses at Rowan University utilized the game as a supplementary tool to assist them with lab work. The overall goal of the improved game system is to improve student comprehension and classroom results. Additionally, the finished system is planned to be fully automated, requiring no intervention from instructors or researchers. Assessments of the effectiveness of the game system will be shown through the following:

In-memory computing (IMC) can eliminate data movement between processor and memory, which is a barrier to the energy efficiency and performance in von Neumann computing. Due to low power consumption, fast operation, and tiny footprint in crossbar architecture, resistive RAM (RRAM) is one of the most promising devices for IMC applications. We present FPCAS, a pipelined floating point (FP) arithmetic (addition/ subtraction) solver based on RRAM crossbars. Although promis- ing, RRAM-based computing may experience random failures, such as the stuck-at fault where RRAM cells are stuck at either a high-resistance state (HRS), i.e., stuck-at-0 (SA0), or a low-resistance state (LRS), i.e., stuck-at-1 (SA1). We propose techniques to prevent SA1 failures, namely, shifting-at-the-output (SATO), force to <inline-formula> <tex-math notation="LaTeX">$V_{\mathrm{ DD}}$ </tex-math></inline-formula> (FTV), and force to ground (FTG) since 96% of the RRAMs employed in our architecture are in HRS. Using an extra clock cycle, both strategies employ the memory array's fault-free RRAMs to conduct the computation. When the failure rate is less than 2%, SATO can manage more than 70% of faults, whereas FTV can handle more than 90% of faults at low power and low area overhead. Simulation results reveal that, for <inline-formula> <tex-math notation="LaTeX">$\mathrm{\scriptstyle NAND}$ </tex-math></inline-formula>–<inline-formula> <tex-math notation="LaTeX">$\mathrm{\scriptstyle NAND}$ </tex-math></inline-formula>- and <inline-formula> <tex-math notation="LaTeX">$\mathrm{\scriptstyle NOR}$ </tex-math></inline-formula>–<inline-formula> <tex-math notation="LaTeX">$\mathrm{\scriptstyle NOR}$ </tex-math></inline-formula>-based implementations, FPCAS consumes 335 and 322 pJ, respectively. Both implementations incur a performance overhead of 50% at the array level and 4% for pipelined FP implementation.


In the last two decades there has been a Worescence of experimental research demonstrating that crosslinguistic disparities foster diUerences in nonlinguistic thought across human populations. The linguistic inWuences on thought that have been uncovered are associated with a number of cognitive phenomena including spatial orientation, quantity recognition, color perception, gender discrimination, and others (Everett 2013). While the extent of such 'relativistic' eUects remains a matter of some debate, their existence is now generally incontrovertible. SigniVcantly, most of the eUects in question relate to crosslinguistic semantic variation instantiated lexically and/or morphologically. One question that remains largely unexplored in such research is whether syntactic crosslinguistic disparities yield diUerences in the way speakers construe associated entities and relationships in nonlinguistic contexts. For instance, as McGregor (2009) notes, it is unclear whether speakers of syntactically ergative languages diUerentiate nonlinguistic concepts (e. g. agency in perceived events) in a more 'ergative' manner than speakers of non-ergative languages. In this chapter I suggest that the framework of Role and Reference Grammar (Van Valin 2005, 2009 inter alia) could be fruitfully utilized in the exploration of potential syntactic eUects on nonlinguistic thought. The strong typological grounding of RRG and its characteristic lack of presuppositions about putatively universal syntactic phenomena such as subject-hood (along with its associated rejection of opaque movement rules and null elements in syntax) make it an ideal approach for distinguishing some of the core ways in which syntactic dissimilarities across languages might create disparities in nonlinguistic thought. I conclude that RRG-speciVc claims about the


Ideas from ecological psychology and nonlinear dynamics characterize adaptive behavior as an emergent property of self-organization processes in the interpersonal interactions that occur between multiple agents in complex social systems such as industrial organizations, academic institutions and sports teams. A conceptual model, proposed to capture constraints on dynamics of decisions and actions in multi-agent systems, was empirically evaluated in simulations of interpersonal interactions in team sports. For this purpose, co-adaptive interpersonal dynamics in the team sport of Rugby Union were studied to model control parameter and collective variable relations in attacker-defender dyads. Videogrammetry analysis revealed how attackers used displacement velocity to generate fluctuations and create phase transitions to destabilize dyadic sub-systems near the try line. Although interpersonal dynamics of multiple agents exhibited characteristics of chaotic attractors, the informational constraints of the team sport of Rugby Union boxed the systems into a low dimensional attractor. Data suggested that decisions and actions of agents in complex systems such as work organizations, academic institutions and sports teams may be characterized as emergent properties, governed by laws of dynamical systems at the ecological scale. Further work is needed to generalize this conceptual model of adaptive behavior in performance to other populations of multiple agents.


AIM
This study was aimed to investigate the associations between single nucleotide polymorphisms of cancer stem cell marker genes, CD44 and CD133, and susceptibility and prognosis of gastric cancer.

PATIENTS & METHODS
Five single nucleotide polymorphisms in CD44 and CD133 genes were genotyped in 898 gastric cancer cases and 992 controls.

RESULTS
The A/C or C/C genotypes of CD133 rs2240688 were associated with decreased risk of gastric cancer comparing with the A/A genotype (odds ratio: 0.81; 95% CI: 0.67-0.97; p = 0.023). The T allele of CD133 rs3130 predicted a worse survival for gastric cancer patients receiving tumorectomy (hazard ratio: 1.28; 95% CI: 1.04-1.58; p = 0.020), independent from tumor node metastasis stage, vessel invasion and postoperational chemotherapy.

CONCLUSION
 CD133 polymorphisms are promising biomarkers for genetic susceptibility and prognosis prediction of gastric cancer.


A method is provided for selectively treating floccu lated heavy metal contaminated iron-based sludges from an industrial waste water treatment process. The method removes the heavy metal contaminants with a minimum loss of the iron therein. The method con prises dissolving the sludge in hydrochloric acid to produce a ferric chloride solution. The solution is fil tered to remove precipitated heavy metal salts, such as lead chloride. The filtrate containing the remaining heavy metal chlorides and ferric chloride is then cooled or otherwise treated to remove additional heavy metal chlorides. The remaining ferric chloride based solution is then reduced (exposed to iron powder) to a ferrous chloride solution and heavy metals. After filtration of any additional precipitated heavy metals, the ferrous chloride solution is ready for recycling. The precipita ted/filtered heavy metal salts can be supplied to one or more conventional recovery processes to produce one or more heavy metals, instead of disposing of them as hazardous waste.


In narratology, focalization is defined as the angle via which things are seen in the
narrative world; also it is accounted as an element present in all narrative genres. As
an independent discipline, focalization starts with Gerard Genette, and it undergoes
various modifications from classical narratology to post-classical narratology. In fact,
there are two basic domains for the discussions of focalization: 1. Genette�s theory, 2.
Post-Genettean approaches. Accordingly, this article aims at introducing focalization
and the related notions to it, plus reviewing Genette�s and post-Genettean approaches,
in addition to making a background on focalization in the modernist view.


This paper focuses on the study of CO2 thermodynamic cycles in order to explore design alternatives for light commercial refrigeration systems. To this end, a testing apparatus was designed and built. With this apparatus the operation conditions, component characteristics and cycle configuration can be easily modified, thereby allowing the experimental evaluation of their effects on the system performance. This paper compares the thermodynamic performance of a CO2 cycle assembled with a variable expansion device coupled to an active control of the discharge pressure with that obtained by a conventional system, assembled with a capillary tube. It is shown that the capillary tube system does not self-adjust to the variations in the operation conditions and therefore is penalized in terms of performance when such variations occur. Additionally, it was demonstrated that the discharge pressure can be properly controlled by adjusting the circuit refrigerant charge, thereby partially compensating the losses occurring when the system diverges from the design point.


Objective To explore the clinical feature,treatment and prognosis of neonatal small intestinal atresia.Methods Retrospective study was carried out of 80 neonatal small intestinal atresias over the last 14 years,including diagnosis,treatment and prognosis.Results Of them,62 cases were healed(77.5%),18 cases were dead(22.5%),24 cases(30%)associated with other anomalities.The living cases were followed up for 6 months to 3 years.These symptoms had not relapse.Conclusions Satisfactry effect can be obtained by early diagnosis and operative treatment.Sonography is an ideal way for early finding intestinal atresias in a fetus.End-to-end single layer anastomosis is an ideal way for monointestinal atresia,and poly-end-to-end single layer anastomosis plus long gastrointestinal silicone tube for supporting is an ideal way for multipal intestinal atresia.


Ongoing calculations on the QCDOC supercomputer at Brookhaven National Laboratory and the APEnext installation at the University of Bielefeld aim to determine the critical temperature of the QCD phase transition as well as the equation of state with almost realistic quark masses. We will discuss preliminary results of the quark mass and cut-off dependence of order parameters, susceptibilities, static quark potentials and the critical temperature in (2+1)-flavor QCD. All these quantities are of immediate interest for heavy ion phenomenology.


Objectives In order to provide a basis for nosocomial infection control,we analyzed the nosocomial infection situation of our hospital during the past five years. Method A retrospective epidemiological study was carried out to investigate the medical records of all cases leaving hospital during the period of 2002 ~ 2006. The rate of nosocomial infection of each year, the site of nosocomial infection, the rate of nosocomial infection of each department and the failing report rate were analyzed. Result During the past five years, the rate of nosocomial infection rised in our hospital especially in the intensive care unit,the site of nosocomial infection occurred mainly in the upper and lower respiratory tract. Conclusion To reduce the rate of nosocomial infection, comprehensive measures should be taken in our hospital especially in the intensive care unit.


AIM: To compare the effectiveness and tolerability of paroxetine vs pregabalin for the management of multiple sclerosis(MS)-induced neuropathic pain(NPP).METHODS: A randomized, flexible-dose open-label 8-wk study involving 21 relapsing-remitting MS patients with MS-induced NPP was conducted to evaluate the effectiveness and tolerability of pregabalin versus paroxetine for pain management. The trial included a 3-wk dose titration phase followed by a 5-wk stable dose phase. Primary outcome measures included daily patient-reported pain intensity as measured using a 100 mm visual analogue scale(VAS pain) and daily impact of pain on daily activities(VAS impact). Hierarchical regression modeling was conducted on each outcome to determine if within person VAS trajectory for pain and impact differed across study groups, during 56 d follow-up. RESULTS: Attrition rates were significantly greater(P 0.001) in the paroxetine versus pregabalin study group(70% vs 18.2%, respectively). Average study duration between study groups also significantly differed(P 0.001). Paroxetine participants completed an average of 27.3 d of treatment vs 49.5 d in the pregabalin group, with the majority of patients withdrawing due to adverse events. Due to the high attrition rates in the paroxetine study arm, the investigators stopped the study prior to achieving complete recruitment. As such, no significant differences between pregabalin and paroxetine study arms were noted for the primary outcome measures(VAS pain, VAS impact). Comparative assessment of baseline patient characteristics also revealed no significant differences between the study arms. CONCLUSION: High attrition rates associated with paroxetine use suggest that it be used with caution for MS-induced NPP. Efficacy outcomes could not be assessed due to attrition.

Vision-based lane departure warning systems (LDWS) use images collected by small cameras to track the pavement markings and warn drivers when their vehicles perform unintended drifts out of the travel lanes. Pavement marking visibility at night is a function of the marking's retroreflectivity. During rain, pavement markings are covered by water, reducing the retroreflectivity and adversely affecting the visibility of the markings at night. This study examines the effects of the marking's retroreflectivity on the performance of LDWS, based on tests conducted in the field and in a simulated rain facility. The results indicate that improving the retroreflectivity attributes of commonly used pavement marking materials such as thermoplastic and paints improves the performance of LDWS for rain conditions at night. In addition, this performance improves significantly with the use of enhanced types of pavement markings that have high visibility during rain.


Osmiophilic inclusions were frequently observed in cells of Ceratocystis ulmi (Buism.) C. Moreau in its hosts and in culture. These inclusions vary in shape, size, or their degree of compactness and are composed of fibrillar material and dense granules that are generally 150 A in diameter. The inclusions are present in vacuolar areas which often appear to be completely or partially devoid of a membrane. Vacuolar areas may also contain aggregates of a similar texture, which often appear to have connections with nearby cytoplasm. Inclusions and (or) aggregates are often adjoining layers of membranes next to or extending within the vacuole. After thymidine labeling, radioautographic grains were observed over these bodies, thus suggesting the presence of DNA. The possible origin of these inclusions from transforming fungal cytoplasm and their importance in the infection process of Dutch elm disease are discussed. A mimeographed English version of the paper is available from the junior author.

We present an efficient preconditioning technique for accelerating the fixed point iteration in real-space Kohn-Sham density functional theory (DFT) calculations. The preconditioner uses a low rank approximation of the dielectric matrix (LRDM) based on Gˆateaux derivatives of the residual of fixed point iteration along appropriately chosen direction functions. We develop a computationally efficient method to evaluate these Gˆateaux derivatives in conjunction with the Chebyshev filtered subspace iteration procedure, an approach widely used in large-scale Kohn-Sham DFT calculations. Further, we propose a variant of LRDM preconditioner based on adaptive accumulation of low-rank approximations from previous SCF iterations, and also extend the LRDM preconditioner to spin-polarized Kohn-Sham DFT calculations. We demonstrate the robustness and efficiency of the LRDM preconditioner against other widely used preconditioners on a range of benchmark systems with sizes ranging from ∼ 100-1100 atoms ( ∼ 500–20,000 electrons). The benchmark systems include various combinations of metal-insulating-semiconducting heterogeneous material systems, nanoparticles with localized d orbitals near the Fermi energy, nanofilm with metal dopants, and magnetic systems. In all benchmark systems, the LRDM preconditioner converges robustly within 20–30 iterations. In contrast, other widely used preconditioners show slow convergence in many cases, as well as divergence of the fixed point iteration in some cases. Finally, we demonstrate the computational efficiency afforded by the LRDM method, with up to 3.4 × reduction in computational cost for the total ground-state


Poverty is a global problem, often associated with needs, difficulties and deficiencies in various living conditions, especially in the agricultural sector. The picture of material shortages which usually includes daily needs for food, clothing, housing, and health services. The problem of poverty in rural areas is more commonly found in dry land-based areas, and the symptoms of poverty are caused, among others, by the relatively less natural carrying capacity, Socio-economic infrastructure is not evenly distributed and institutions have not yet reached the local community and the quality of human resources is still relatively low.

This essay looks at the public health consequences of U.S. development aid to both India and PEPFAR. A close analysis of the U.S.-India development aid relationship presents an important case study for the purposes of this essay, as it is one of the oldest and longest development aid stories in U.S. history. The evolution of U.S. development aid is traced throughout its history with India. In other words, the varying outcomes that occurred as a result of the presence of paternalism in U.S. development aid are chronologically imprinted in its development aid relationship with India, an important component when assessing the influence of U.S. foreign and domestic policy over its development strategies. The case study therefore, provides critical information that will allow certain assumptions to be made about the future of PEPFAR as U.S. development aid manifests in a similar pattern to India's experience. These two state development aid cases are deemed as success stories, from a U.S. standpoint, which highlights the external public health outcomes. The parallels that can be drawn between the paternalistic manifestations in the U.S.-India development aid relationship and PEPFAR programs currently being implemented in focus countries, are explored in order to try and understand the future public health outcomes of the PEPFAR program. Foucault: Criticism is a matter of flushing out that thought and trying to change it: to show that things are not as self-evident as one believed, to see that what is accepted as self-evident will no longer be accepted as such. Practicing criticism is a matter of making facile gestures difficult.

Abstract Purpose of the study is to find a faster and simpler way to identify the silver fir (Abies alba Mill.) from Serra San Bruno (Catanzaro). A morphological and anatomical analysis comparing the Serra San Bruno provenance and the Vallombrosa provenance detected that the SSB provenance had a higher percentage of needles with pointed apex and with stomata on the adaxial side, a greater number of stomatal rows per band, a greater number of stomata per 1 mm segment and per mm2, a greater thickness of the mechanical tissue (epidermis and hypodermis) and the palisade parenchyma, and a smaller diameter of the resin ducts. Observations with the electron microscope confirm these differences and show up the greater xeromorphic adaptation of the SSB provenance. Since many PSSB traits are retained when the provenance is transplanted outside its natural area of distribution, they are probably genetic in origin.

Objective To explore the cloning,prokaryotic express and purification of the receptor for activated C kinase 1(RACK1) gene of RH strain of Toxoplasma gondii,and to analyze the antigenicity of recombinant protein.Methods Total RNA was extracted from tachyzoites of RH strain of T.gondii.The open reading frame of TgRACK1 gene was amplified with a pair of specific primers which was designed according to the coding sequence of TgRACK1 gene(GenBank accession No: AY547291),the product of RT-PCR was digested with double restrict enzyme and ligated into a pGEX-6p-1 vector.The recombinant pGEX-6p-1-TgRACK1 plasmid was transferred into E.coli DH5α and the positive clones were selected through the colony-PCR and confirmed by the double restrict enzyme digestion and sequencing.The successful pGEX-6p-1-TgRACK1 construct was transformed into E.coli BL21(DE3) and induced with IPTG to express.The products of expression were analyzed through SDS-PAGE followed by Coomassie blue staining and the recombinant TgRACK1 was purified by using glutathione-triethyleneglycocyl-sepharose 6B.Western blotting assay with GST primary antibody and rabbit anti-T.gondii serum were used to confirm the expression of rTgRACK1 and analyze its antigenic properties.Results The product of RTPCR was 970 bp.The recombinant plasmid pGEX-6p-1-TgRACK1 was confirmed successfully by colony-PCR,double restrict enzyme digestion and sequencing.A recombinant protein with a rough molecular weight of 63 kDa was analyzed via SDS-PAGE followed by Coomassie blue staining.The GST tag in rTgRACK1 and the antigenicity of rTgRACK1 were detected efficiently by Western blotting analysis with the GST primary antibody and with the prepared antiserum against TgRACK1 respectively.The isolated protein was water soluble and showed 95% purity based on SDS-PAGE and gel imaging analysis.Conclusion The TgRACK1 gene is cloned,the recombinant protein TgRACK1 is produced in E.coli and purified and maintained the specific antigenicity.


January 27, 1928—This is a small storm with abrupt beginnings recorded on all three of the components. Beginning at 10h 30m H and Z drop considerably and come back to normal about an hour later, making the curves appear like a sharp wedge at this time. The active part begins at 9h and lasts about four hours.

March 11, 1928—The beginning of this storm is gradual, the Z seeming to just wander up and off the paper till the storm is over. The D and H are moderately active until the thirteenth hour, D increasing and H decreasing to that time. From 13h to 16h these elements are very active, the spots being faint lines only because of the rapidity of the motion, and both record very low values. At 16h the storm begins to decrease with fluctuations and is soon back to normal.


Objective To observe the effects of the purine receptor P2x7 in the microglia inflamation. Methods The recombinant plasmid pCDNA3.1 was constructed and sequenced. Then the plasmid was transfected by Lipo2000 into the microglia cell line BV-2. The mRNA expressions and the protein expressions of the P2x7 and Cox-2 were detected by PCR and Western blot, respectively. Result After the plasmid was transfected, the mRNA expressions of P2x7 and the protein expressions of P2x7 and Cox-2 were significantly increased (P 0.05). Conclusion After over-expression P2x7, the microglia is activated, and then induced inflamation.


Individuals infected with the novel coronavirus (Severe Acute Respiratory Syndrome Coronavirus 2 [SARS‐CoV‐2]) who develop coronavirus disease 2019 (COVID‐19) experience many symptoms; however, cutaneous manifestations are relatively rare. The authors encountered three patients with COVID‐19 who presented with erythema and suspected viral rash. In all cases, erythema appeared after the onset of the initial symptoms of COVID‐19. Erythema was considered to be caused by COVID‐19 and not a drug‐induced eruption because, in all cases, erythema was relieved merely by external medicine and oral antihistamines, without discontinuing the original medication. The authors' hospital accepted 69 COVID‐19 patients between 22 February 2020 and 31 May 2020 and, of these, three (4.3%) exhibited eruptions, and all cases presented erythema. Except for seven patients who exhibited positive nasopharyngeal swab tests for SARS‐CoV‐2 RNA but no symptoms, three (4.8%) of the remaining 62 patients exhibited erythema. Although various types of eruptions have been reported in patients with COVID‐19, erythema was the only type in our patients. Erythema in the three patients exhibited many similarities to that previously reported in COVID‐19 patients, particularly in the manner it appeared and disappeared. For these reasons, these three cases were considered typical examples of erythema in patients with COVID‐19. Considering previous studies and the three cases reported here, there is a high probability that SARS‐CoV‐2 can cause erythema.


The utility model discloses a mechanical device for loading, unloading, heaping and piling bagged and tied goods in groups. A tension pre-tightening mechanism is composed of a member of an upper power bearing board frame, a member of a lower power bearing board frame, a versatile fixed pulley, and wire rope. When the utility model is hoisted, the grouped goods are effectively positioned and controlled integrally. Goods are avoided from being dropped off in loading and unloading operation. The operation of loading, unloading, heaping and piling bagged and tied goods in groups is safely ensured. The utility model has the advantages of simple structure, easy fabrication, low cost, strong adaptability of the working operation to the bearing rope belt, small failure rate, etc.


The term "world trade talks" conjures up images of blue-suited officials deep in esoteric discussion on tariffs and quotas that would make most people's eyes glaze over. But activists from around the world are pledging that trade talks this week in Seattle will be anything but stodgy. They are converging on the meeting, which runs through Dec. 3, to demonstrate and to call for governments to review and reform the World Trade Organization (WTO) before launching a new round of talks on liberalizing world trade. Governments created WTO in 1995 to expand international trade by reducing barriers such as tariffs and by preventing discrimination against imported goods and services. Countries that are members use WTO to settle trade disputes. If WTO dispute resolution panels decide in favor of a nation challenging another country's laws or regulations, the victor is allowed to impose trade sanctions against the loser. The Seattle conference will convene highest level trade ...


The Association of Anaesthetists of Great Britain and Northern Ireland (AAGBI), in conjunction with the Intensive Care Society, the Royal College of Anaesthetists and the Faculty of Accident and Emergency Medicine has previously published guidelines on syringe labelling in critical care areas in May 2003 and June 2004. These guidelines are based on a colour-coded labelling system primarily intended for syringes being used to administer drug boluses manually. All drugs with similar clinical actions are labelled in the same colour. This aims to minimise the risk of inadvertently administering a drug with different pharmacological actions in much the same way that gas cylinders in hospital have a colour-coding system.


Estimating individual treatment effect (ITE) is a challenging task due to the need for individual potential outcomes to be learned from biased data and counterfactuals are inherently unobservable. Some researchers propose to use generative adversarial approaches to infer the counterfactual outcomes based on the distribution of factual outcomes. However, these methods assume that complete confounding factors are observed, and simply treat all observed variables as confounding factors, ignoring identification of possible instrumental factors and adjustment factors, which will bring large deviation to ITE estimation when facing biased data. To address these issues, we propose a novel Variational Generative Adversarial Nets for ITE estimation by designing the collaborative learning strategy with Variational AutoEncoder (VAE) and Generative Adversarial Nets (GAN). Specifically, we employ VAE to infer the latent representations of observed variables to access complete latent factors while using GAN to infer unseen counterfactual outcomes and guide VAE for disentangling these latent factors into three sets corresponding to the instrumental, confounding, and adjustment factors. Then the disentangled latent confounding factors can be used to further control data bias using an adaptive weighting scheme. Extensive experiments on real and synthetic data demonstrate learning disentangled latent factors for ITE estimation is effective, and our method has excellent performance even with high data bias.


Candidatus Mycoplasma haemohominis (cMh) is the most human-adapted and lethal hemoplasma. Bats are the common reservoir worldwide. cMh should be suspected in PUO associated with splenomegaly, and hemolytic anaemia or hemophagocytic lymphohistiocytosis, above all in Asia Pacific travellers. Doxycycline can be started preemptively as diagnosis can be retrospectively confirmed.


Article Information: The mapping of science and the information sciences To cite this article: David Bawden, (2011) "The mapping of science and the information sciences", Journal of Documentation, Vol. 67 Iss: 6, pp.-It is just over 50 years since Derek de Solla Price produced his best known work: " Little Science, Big Science " (de Solla Price, 1965). It was on the required reading list for my information science masters course, and – I suspect like many other students of the subject at that time – I wondered what it was doing there. It took some while before I realised that Price's work, which founded the subject known generally known as scientometrics, was intimately connected with the information sciences, building on the laws of " statistical bibliography " developed earlier by Bradford, Zipf, Pareto and the rest. It now is taken for granted that bibliometrics and scientometrics are an integral part of information science, albeit that they overlap into other disciplines. Just how far they have come since Price's day, with particular encouragement from the development of information visualisation techniques in the last decade, is shown in a remarkable new book (Börner, 2010). That an atlas of science of this sort, which rightly claims to set out the evolution of scientific knowledge, disciplines and applications, should be complied by a professor of information science, as Katy Börner is, shows the extent to which Price's ideas have been adopted by our discipline. A beautifully produced, and very large, book, it accompanies a physical exhibition of science maps, running until 2014 and continually augmented with new material. The core of the book is a series of 31 examples of mappings of science and scientific progress: from Napoleon's march on Moscow to the period table, and from Wikipedia's coverage of scientific issues to visualisations of DNA development and patent applications. Fascinating in themselves, they put this book, to my mind, on a par with the books by Tufte (1997) and Barrow (2008), as exemplifications of good use of images in conveying complex information and ideas. The book is much more than this, however: indeed, this is only one of five parts. Of particular interest to anyone reflecting on the relations between the mapping of science and information disciplines is the second part, covering the history of science maps, and the third, covering the development of the " science of science ". Here we …


Assignment to the research arm of the Alameda County Health Department, Califs brings unusual activity. While nurses teach birth control, do multiphasic geriatric screening, and have expanded roles in child health supervision, most of their services go to newcomers and to high-risk prenatal patients.


Highway capacity is often subject to stochastic perturbations due to the combined effects of weather, traffic mixture, driver behavior, etc. This paper is motivated by the need of a systematic approach to traffic control with performance guarantees in the face of such perturbations. We develop a novel control-theoretic method for designing perturbation-resilient ramp metering. We consider a cell-transmission model with 1) Markovian cell capacities and 2) buffers representing on-ramps and upstream mainline. Using this model, we analyze the stability of on-ramp queues by constructing piecewise Lyapunov functions that consider the nature of nonlinear traffic dynamics. Then, we design ramp controllers that guarantee bounds for throughput and queue sizes. We also formulate the problem of coordinated ramp metering as a bi-level optimization with non-convex inner sub-problems. To address the computational issue in solving this problem, we also consider localized and partially coordinated reformulations. A case study of a 18.1-km highway in Los Angeles, USA indicates a 8.3\% (resp. 9.9\%) reduction of vehicle-hours-traveled obtained by the localized (resp. partially coordinated) control, both outperforming the classical ALINEA and METALINE controllers.


The Constitution on the Sacred Liturgy (Sacrosanctum Concilium) of the Second Vatican Council reinvigorated the role of the Scriptures within the Eucharistic Liturgy, "where the treasures of the Bible are to be opened up more lavishly, so that richer fare may be provided for the faithful at the table of God's word" (no. 51). This renewed Liturgy of the Word gave "an exceptional place" to the role of the ancient homilia or homily as the site for the Christian assembly to attend to Sacred Scripture and its proclamation of the workings of God in Christ throughout human history. Later, the USCCB's marvelous statement on liturgical preaching, Fulfilled in Your Hearing: The Homily in the Sunday Assembly (1982), would remind us that the preacher is a "mediator of meaning" (7), who interprets both the Scriptures and the complexities of modern culture in a word of grace for the Christian assembly. Yet, the restoration of the homily and its discursive form poses potential problems. Indeed, this invitation to discover a user-friendly, "conversational" preaching idiom presents difficulties with structuring the homiletic text, often losing hearers in the process. Kenneth Untener's Preaching Better (1999) asserts that the


This chapter discusses the complexity of eHealth implementation from a theoretical and practical perspective. In the first part of this chapter, several theories and frameworks regarding implementation are introduced and critically discussed, e.g. the Diffusion of Innovation Theory, the RE-AIM framework and the Consolidated Framework for Implementation. After that, several examples from practice are discussed and connected to issues with implementation. These examples illustrate the relationship between implementation and four main topics: eHealth development, characteristics of the technology, financing and the healthcare context. The chapter finishes with a critical look at current implementation theories.


Abstract A series of Asteraceae, belonging to the tribes Astereae, Eupatorieae, Helenieae and Heliantheae, have been analyzed for the presence of flavonoid aglycones accumulated on leaf and stem surfaces. Methyl ethers of apigenin, luteolin, kaempferol, and quercetin as well as methyl ethers of their relevant 6 -hydroxy derivatives were abundant, whereas 8 -O-substi-tuted derivatives and flavanones were encountered only occasionally; 6 ,8 -di-O-substituted flavonols were found in only one species.


Photolysis of several enol esters produces the corresponding 1,3-Fries products, i.e. the keto forms of the β-diketones, as the sole primary photoproducts. The quantum yields of the rearrangements under a variety of conditions were measured. They decrease when the number of fused aromatic rings in the acyl part of the molecules is increased. The photobehaviour of the 2-anthroyl derivative is exceptional, in being affected both by the exciting wavelength and the solvent. Its irradiation at 254 nm results in a photo-Fries rearrangement (p.f.r.) with a yield twice that in ethanol; irradiation at 366 nm causes only inefficient dimerization. Explanations are forwarded for the general photobehaviour of the enol esters and its relation to the 1,3-p.f.r. of aryl esters and to other photoinduced 1,3-shifts.


In this paper, we use the linear programming approach to mechanism design, rst introduced by Sethuraman et al. (2003) and then systematized by Vohra (2011), to analyze nondictatorial Arrovian social welfare functions with and without ties. First, we provide a new and simpler proof of Theorem 2 in Kalai and Muller (1977), which characterizes the domains admitting nondictatorial Arrovian social welfare functions without ties. Then, we show that a domain containing an inseparable ordered pair admits nondictatorial Arrovian social welfare functions with ties, thereby strengthening a result previously obtained by Kalai and Ritz (1978). Finally, we propose a reformulation of the simple majority rule in the framework of integer programming with an odd or even number of agents. We use this reformulation to recast some celebrated theorems, proved by Arrow (1963), Sen (1966), and Inada (1969), which provide conditions guaranteeing that the simple majority rule is a nondictatorial Arrovian social welfare function.

The growing global population, with its increasing need for energy and food, presents a challenge for the planet: How can the ever-increasing demand for these resources be met in a sustainable manner? This is of particular importance in light of climate change: Emissions of greenhouse gases from energy and food production causes climate change. More people means more demand for energy and food production, and more demand for production means more carbon emissions. The focus of this paper is on how we can try to meet this challenge of boosting agricultural productivity to meet the needs of the Earth's ever hungrier population. The paper looks at this challenge through 2050, and presents as-of-yet unpublished data from agricultural models.The changing patterns of climate can potentially have severe impacts on agricultural productivity both ecologically as well as economically. Due to shifting precipitation patterns, movement of insect populations, more dramatic shifts in daily temperature regimes, and other large scale ecological changes that come with climate change, agriculture will most likely be severely impacted by climate change. The move to increase production for biofuels to reduce transport emissions is a further feedback loop linking agriculture to climate change. Skillfully managing this interaction between agriculture and climate change is a grand challenge.Our conclusion is that it is going to be hard to meet the challenge and all available technologies will be looked at and massive investment will be required.
