Abstract Nonhomogeneous copolymer systems that follow Markovian kinetics on a microscale will give non-Markovian sequence distributions in the polymer produced. This is because each microdomain is statistically independent of the others and the assumption of statistical stationarity does not apply. Equations that consider non-homogeneity, however, do apply and can reconcile Markovian kinetics and non-Markovian sequence distributions. Failures of systems to follow lower order Markovian mechanisms based on distribution data should be reviewed for nonhomogeneity. Complex mathematical models that can never be validated experimentally should only be considered if nonhomogeneity fails to explain the data adequately.


Background. The objectives were to test the hypothesis that certain strains of microorganisms are present in fetal blood in a significant proportion of parturient women suffering unexplained third trimester fetal death, and to examine the correlation between fetal bacteremia and histologic chorioamnionitis and vasculitis.


Electro-Fenton (EF) and peroxyelectrocoagulation (PEC) processes were investigated to mineralize 10 mg L−1 erythromycin from ultrapure water, evaluating the influence of the anode material (BDD and Fe), current density (janode) (5 mA cm−2 and 10 mA cm−2), oxygen flowrate injected to the cathode (0.8 L min−1 O2 and 2.0 L min−1 O2) and pH (2.8, 5.0 and 7.0) on the process efficiency and the electricity costs. 70% mineralization was reached after applying 0.32 A h L−1 under the best operational conditions: PEC treatment at 5 mA cm−2, 2.0 L min−1 O2 and pH 2.8. The electricity consumption of the electrochemical cell under these conditions was approximately 0.3 kWh m−3. Early-stage intermediates produced from erythromycin degradation were identified and quantified throughout the treatment and a potential erythromycin degradation pathway was proposed. The most appropriate operational conditions tested with synthetic solutions were applied to treat a real effluent from the tertiary treatment of an urban wastewater treatment plant. All emerging compounds listed in the EU Decision 2018/840 (Watch List 2018) were determined before and after the PEC treatment. All listed pollutants were degraded below their quantification limit, except estrone and 17-α-ethinylestradiol which were 99% removed from water. Electricity consumption of the electrochemical cell was 0.4 kWh m−3. Whilst awaiting future results that demonstrate the innocuity of the generated byproducts, the results of this investigation (high removal yields for emerging pollutants together with the low electricity consumption of the cell) indicate the promising high potential of PEC treatment as a water treatment/remediation/regeneration technology.


This paper aims to discuss the role of CLIL (Content and Language Integrated Learning) as one of the most experimental and challenging teaching and learning methods from primary through to adult and higher education. As demonstrated by the Council Conclusions on Language Competences to Enhance Mobility (Council of the European Union, 2011), CLIL is still on the agenda of the European Union. Crucially, its success will be determined by assessing a case study that involves the Italian education policy. The Italian Ministry of Education has mandated CLIL as an approach to be adopted for teaching non-lingua subjects in the last year of Italian secondary school and Italian technical high school by 2013. This policy moves Italian educators under the limelight of the international education arena where one of the main challenges is to move beyond traditional teacher-centered lecturing towards learner-centered ways of learning. Italian teachers should realize that educators across the world will be watching them apply "the CLIL-Potential" and outcomes from Italian CLIL classrooms will help define CLIL best practice. In the light of these premises, the research attempt here is a) to investigate Italian primary teachers' feelings, attitudes and expectations toward the great potentiality of the CLIL approach thanks to a questionnaire to be administered to a selected schools located in Southern Italy; b) to discuss how selected authentic CLIL materials can be used and implemented in a primary and secondary education settings.


The article will present the role of the humanitarian aid in the process of creating the US foreign policy. The study will examine two interesting case studies: the Polish Medical Aid Project and the creation of the American Research Hospital for Children in Poland. The work will show the most important aspects of the planning and implementation of those initiatives. This approach will be aimed at answering the title question and will try to define the extent to which the humanitarian aid offered to Poland within a certain period was a political calculation. The final analysis of the congressional hearings conducted in 1962 presents and confirms the complexity of the process of helping the "Captive Nations" in Central Eastern Europe.


This study proposes an integrated physically based distributed model for inundation flows. It has four sub-models: a hydrological model for rainfall-runoff, a two dimensional shallow water model for overland flows, a one dimensional model for flows in sewer networks, and a data management model. The 2-D shallow water model is at first tested against the physical experiments about the inundation due to levee breach. Then the model is applied to the inundation caused by the extreme tidal surge in Takamatsu city, a local capital in Japan in 2004. Comparisons with measured data show that the model reasonably describes the inundation process in the urban area and that the sewer network played an important role in draining the sea water.


Epidemiological and clinical studies suggest that an increased intake of dietary selenium significantly reduces overall cancer risk, but the anticancer mechanism of selenium is not clear. In this study, we fed intestinal cancer mouse model. Muc2/p21 double mutant mice with a selenium‐enriched (sodium selenite) diet for 12 or 24 weeks, and found that sodium selenite significantly inhibited intestinal tumor formation in these animals (p < 0.01), which was associated with phosphorylation of JNK1 and suppression of β‐catenin and COX2. In vitro studies showed that sodium selenite promoted cell apoptosis and inhibited cell proliferation in human colon cancer cell lines HCT116 and SW620. These effects were dose‐ and time course‐dependent, and were also linked to an increase of JNK1 phosphorylation and suppression of β‐catenin signaling. Reduced JNK1 expression by small RNA interference abrogated sufficient activation of JNK1 by sodium selenite, leading to reduced inhibition of the β‐catenin signaling, resulting in reduced efficacy of inhibiting cell proliferation. Taken together, our data demonstrate that sodium selenite inhibits intestinal carcinogenesis in vivo and in vitro through activating JNK1 and suppressing β‐catenin signaling, a novel anticancer mechanism of selenium.


Objective:To explore the clinical significance of diagnostic hysteroscope in the diagnosis of endometrial carcinoma and the relationship of diagnostic hysteroscopy and positive peritoneal cytology.Methods:A retrospective study was carried out on 113 cases of endometrial carcinoma.Among them,71 patients were diagnosed by dilatation and curettage(DC),42 patients were diagnosed by hysteroscopy.The pre-and post-operation diagnoses,histological type,the coincidence rate of histology and positive rate of peritoneal cytology in the two groups were compared,and correlation of positive peritoneal cytology with histology type,differentiation(grade),depth of myometrial invasion,adnexal metastasis and tumor distribution in the uterine cavity were analyzed.Results:The pathological coincidence rate before and after operation in hysteroscopy group was 97.62%,which was significantly different from that of 83.10% in DC group(P0.05).The positive peritoneal cytology rate was 28.57% in hysteroscopy group,which was higher than that in DC group(25.35%),but no statistical difference was found(P0.05).The positive peritoneal cytology rate was significantly correlated with tumor distribution in the uterine cavity(P0.05),but not correlated with histology type,differentiation(grade),depth of myometrial invasion and adnexal metastasis(P0.05).Conclusions:Hysteroscopy has higher diagnostic accuracy in endometrial carcinoma than DC,and does not increase the positive rate of peritoneal cytology,which only has a correlation with tumor diffuse distribution in uterine cavity.


This work describes in detail the kinetic model for the cure of an epoxy-anhydride thermoset matrix resin system. The cure kinetics in both nonisothermal and isothermal modes has been characterized using differential scanning calorimetry. The Sestak–Berggren two-parameter autocatalytic model was used to describe the nonisothermal cure behavior of the resin satisfactorily. The isothermal cure data was fitted with Kamal's four-parameter autocatalytic model, coupled with a diffusion factor. These characterization data will form material property inputs for a multiscale modeling framework for the estimation of cure-induced residual stresses in thick thermoset matrix composites. © 2012 Wiley Periodicals, Inc.

Light addressing is an emerging technique to optically address a virtual electrode on a photoconductive substrate. A thinner photoconductive layer of a light-addressable planar electrode can improve the spatial resolution of the light-addressed electrode. Voltage application to the electrode, however, causes a strong electric field across the thin photoconductive layer with a significant avalanche effect, which induces an undesired increase of dark current. In order to overcome this problem, we investigated how photoconductive-layer thickness and passivation-layer conductivity affect voltage-application-induced bright and dark charge densities. Suppression of the dark charge density with a thick photoconductive layer and a low-conductive passivation layer is found to be a key factor for optimization of the light-addressable electrode. With this design strategy, we developed a novel light-addressable electrode using titanium dioxide as a photoconductor. To suppress the avalanche effect, the thickness of the titanium-dioxide layer was designed to be 1.5 μm. The fabricated electrode turned out to have sufficient photoelectric properties: the bright charge density reached 70 μC/cm2 and the bright-to-dark charge density ratio was greater than 10, which allows stimulation to cultured dissociated neurons. © 2010 Wiley Periodicals, Inc.

Although a tremendous effort has been made to perform a reliable analysis of images and videos in the past fifty years, the reality is that one cannot rely 100% on the analysis results. The only exception is applications in controlled environments as dealt in machine vision, where closed world assumptions apply. However, in general, one has to deal with an open world, which means that content of images may significantly change, and it seems impossible to predict all possible changes. For example, in the context of surveillance videos, the light conditions may suddenly fluctuate in parts of images only, video compression or transmission artifacts may occur, a wind may cause a stationary camera to tremble, and so on. The problem is that video analysis has to be performed in order to detect content changes, but such analysis may be unreliable due to the changes, and thus fail to detect the changes and lead to "vicious cycle". The solution pursuit in this paper is to monitor the reliability of the computed features by analyzing their general properties. We consider statistical properties of feature value distributions as well as temporal properties. Our main strategy is to estimate the feature properties when the features are reliable computed, so that any set of features that does not have these properties is detected as being unreliable. This way we do not perform any direct content analysis, but instead perform analysis of feature properties related to their reliability.


I compared habitat composition and pattern between core territory areas centred on nest areas and random plots at 2 meso-territory scales (177 ha and 400 ha) within 78 goshawk territories in west-central British Columbia. Habitat composition and several fragmentation metrics (patch density, largest patch index, core area, edge, contagion, and habitat diversity) differed significantly (P 80% mature forest. Core territory plots also had higher values for core area, contagion, and largest patch index and lower values for patch density, edge, and habitat diversity (i.e. core territory plots were less fragmented). Patterns were similar for the 400 ha scale, although relative differences between core territory and random plots were smaller. This is the first study to examine the importance of meso-scale habitat composition and pattern within goshawk territories. My results highlight the importance of including meso-territory scale factors in habitat selection studies and habitat suitability mapping projects (e.g. Habitat Suitability Index and Resource Selection Function models), which have traditionally focussed on local, stand-level characteristics. My results also support management strategies to maintain concentrations of mature forest and limit fragmentation at meso-territory scales surrounding goshawk nest areas.


Written during the 'Year of Mercy' (2016) proclaimed by Pope Francis, this study examines the role of mercy from the perspective of law codes. State law, human rights law, and religious law can all be vehicles of mercy—though seeming to require that the recipient meets any necessary 'deserving' criteria. This study argues that divine law reaches beyond notions of innocence or repentance, and directs mankind to follow the example of divine love, in being 'unconditionally' concerned with the welfare of the 'other', and posits that mercy, when tempered in the interests of social cohesion, or shown for the sake of earthly or heavenly reward, whilst endorsed in a variety of religious texts, falls short of the ideal which Aquinas refers to as 'the supreme virtue in man'.

Although hair growth medications have been developed, these medications have some side effects and usability problems. Recently there has been a growing interest in hair loss remedies from natural materials. This Study was carried out to investigate the effect of SM-215 on hair growth by hair follicle stimulation. We divided the 8-week-old ICR mice into a Control Group (CG), a Non-Treatment Group (NTG), and a SM-215 application Group (SMG). 100μl/day of SM 215 was applied for 3 weeks to SMG. After 3 weeks, we found a change to the sebaceous gland, the capillaries around the hair follicles (Vascularity and Vasodilation of capillaries), and changes in the hair follicle activity (Growth-promoting hormones, Neurotransmitters) in a tissue sample excised from the dorsal skin. A large number of hair and hair follicles in the subcutaneous layer of SMG was observed as compared to the NTG. Sebum secretions around the hair follicles and sebaceous gland distribution of SMG were observed more clearly than in NTG. A large number of capillaries, especially in the hip region versus the neck region in SMG, were also observed compared to the NTG as noted through external capillaries observation. Positive responses of IGF-1, serotonin, and neuropeptide Y in SMG were increased compared to the NTG in immunohistochemistry. Based on these studies and analysis, we suppose that SM-215 improves a hair growth activity by increasing the distribution of the sebaceous glands, capillaries around the hair follicles, and the vasodilation to assist in forming the necessary environment for hair growth, thereby promoting hair growth by stimulating at hair follicles.


An online evaluation technology for network in- duced time delay by redesigning the application protocol with- out any additional apparatus is proposed in this paper.Firstly, a computational method for network-induced time delay online evaluation and a lower bound on the transmission period are achieved by using automatic route trace technology (ARTT). Secondly,a simple decision-making for the data packet dropout is also discussed.Finally,the controller co-design is described. The effectiveness of the proposed schemes is validated by exper- iments.


Global wiring of integrated circuits is an engineering application using both combinatorial optimization and statistical physics. In this paper, we interpret the problem of how to best wire an integrated circuit as a combinatorial optimization problem. We employ a random search technique, namely, the simulated annealing algorithm, to nd near-optimal solutions of the combinatorial optimization problem. As it turns out it is well-known that the objective function of this optimization problem has the form of a Hamiltonian of an Ising model which has connections to the study of phase transitions. This paper is a continuation of [1]. To describe the wiring problem, we brie y review some of the discussions in [1]. Let us suppose the wires will be laid out in a square grid, say, G = f(x; y) 2 ZZ : 1 x n; 1 y ng for some positive integer n. Let the points (or nodes) in G represent the sources and sinks of the wires. We say that (x1; y1); (x2; y2) 2 G are adjacent points or adjacent nodes if either (x1 + 1; y1) = (x2; y2), (x1 1; y1) = (x2; y2), (x1; y1 + 1) = (x2; y2), or (x1; y1 1) = (x2; y2). The line segment joining two adjacent nodes is called a link. Note, the number L of links in G is given by L = 2n(n 1). We suppose that it has been determined in advance that certain pairs of points or nodes have to be connected. A wire which starts at one node and ends at another node in the same vertical or horizontal line as the rst node will be called a straight wire. We suppose that all wires must be placed along the links. A non-straight wire joining two nodes can be placed (also along the links) in at least two di erent paths. A wire which follows a path with only one bend is said to have an L-shaped path. In this paper, the authors restrict themselves only to straight wires and L-shaped wires.


Reclaimed land contains a large amount of soluble salts and exchangeable sodium in the soil, so it is necessary to select and cultivate tolerant crops that are resistant against salt stress. Chinese cabbage, a staple ingredient in kimchi, is an important vegetable that accounts for most of the production area of leafy vegetables in Korea, but no cases have been reported of growing cabbages in reclaimed land to examine growth and glucosinolate content. The objective of this study was to analyze the growth, nutrient absorption characteristics, and glucosinolate content of Chinese cabbages grown in spring and autumn on reclaimed land with irrigation water with different salt concentrations. The salt concentrations of the irrigation water were 0, 2, and 4 dS∙m -1 . Growth of spring and autumn Chinese cabbages did not change according to the salt concentration of the irrigation water, and only autumn Chinese cabbages showed an increase of Na content according to the salt concentration of the irrigation water. The total glucosinolate content tended to decrease when the salt concentration of irrigation water increased. The increase in salt concentration of irrigation water may reduce the bitterness of autumn Chinese cabbage. Here, it was confirmed that Chinese cabbage cultivation is possible even if the salt concentration of irrigation water reaches 4dS·m -1 on reclaimed land, and the glucosinolate content of autumn Chinese cabbage decreases when salt concentration increases. Additional key words: macronutrient, micronutrient, salt stress, secondary metabolite, sodium chloride


Since the reform and opening up,China has explored continually about the construction of personal income distribution principle and distribution system.The income distribution system has developed from the sole choice of distribution according to work to the distribution according to the contribution of each production factor;from the principle of allowing some people to become rich first to the promotion of labor income proportion in the initial distribution;from the only emphasis on basic income to the perfection of social security.It is natural and inevitable.


Being the only U.S. Government entity charged with monitoring the meteor environment, the Meteoroid Environment Office has deployed a network of all sky and wide field meteor cameras, along with the appropriate software tools to quickly analyze data from these systems. However, the coverage of this network is still quite limited, forcing the incorporation of data from other cameras posted to the internet in analyzing many of the fireballs reported by the public and media. A procedure has been developed that determines the analysis process for a given fireball event based on the types and amount of data available. The differences between these analysis process will be explained and outlined by looking at three bolide events, all of which were large enough to produce meteorites. The first example is an ideal event a bright meteor that occurred over NASA's All Sky Camera Network on August 2, 2014. With clear video of the event from various angles, a high-accuracy trajectory, beginning and end heights, orbit and approximate brightness/size of the event are able to be found very quickly using custom software. The bolide had the potential to have dropped meteorites, so dark flight analysis and modeling was performed, allowing potential fall locations to be mapped as a function of meteorite mass. The second case study was a bright bolide that occurred November 3, 2014 over West Virginia. This was just north of the NASA southeastern all-sky network, and just south of the Ohio-Pennsylvania network. This case study showcases the MEO's ability to use social media and various internet sources to locate videos of the event from obscure sources (including the Washington Monument) for anything that will permit a determination of a basic trajectory and fireball light curve The third case study will highlight the ability to use doppler weather radar in helping locate meteorites, which enable a definitive classification of the impactor. The input data and analysis steps differ for each case study, but the goals remain the same a trajectory, orbit, and mass estimate for the bolide within hours of the event, and, for events with a high probability of producing meteorites, a location of the strewn field within a day. **************************************


Mr. Alex D. Krieger's (pp. 355, 359) reference to the late J C. Jones' date for Lake Lahontan calls for some clarifying comments. Lake Lahontan, the ancient lake in northr western Nevada which occupied 8500 square miles and reached several hundred feet above the modern lakes in its basin, Professor Jones believed, was not, as generally held, contemporaneous with the extensive Pleistocene glaciations in the adjacent mountains,1 but "the Lahontan stages occurred during the present era, with the survival of the fauna till the last thousand years" (1933, p. 96). The extinct fauna referred to included horses, elephants, camels, and Felis atrox (1925, p. 49; 1929, p. 539). Jones (1925, p. 4) did not correlate Lake Lahontan with other ancient lakes in the Great Basin, did not discuss their relationship, and objected to my introducing the obvious sister-lake in western Utah, Lake Bonneville, into the discussion.


The invention relates to a fixing fixture of a throwing machine table and the window-type press board thereof. The window-type press board is used for pressing the upper surface of a bearing board, and comprises a press board body, at least one window hole, and at least one cushion device, wherein the window hole passes through the press plate body for exposing the partial upper surface of the bearing board, the cushion device is arranged outside the window hole and comprises a butting end, when the window-type press board presses the upper surface of the bearing board, the butting end supports against the upper surface of the bearing board; when the window-type press board is lifted up, the butting end pushes the bearing board away downwards to prevent the bearing board from being liftedup along with the window-type press board. Thus, the warping of the bearing board can be avoided, and thereby improving the yield.


The three types of background noise on conversational speech intensity in individuals with hyperphonia and Parkinson's Diseases (PD), are discussed. Researces on PD subjects show that a Lombard relationship exists along with the control subject that may be related to a number of factors such as the severity of hypophonia, the type of background noise, the noise levels, the speech tasks, and the method of stimulus presentation. The subjects with PD are stabilized on their anti-Parisian medication and are tested at about one hour after their regular medication. Two separate two-factors repeated measures ANOVAs are used to examine the effects of each noise type on speech intensity. For each noise type, the group x noise level interaction is insignificant that reveals very few significant differences. The positive relationship between speech intensity and background noise is approximately parallel to that of controls.

INTRODUCTION Shoulder arthroplasty (SA) is an effective procedure for managing patients with shoulder pain secondary to degenerative joint disease or end stage arthritis that has failed conservative treatment. Insurance status has been shown to be an indicator of patient morbidity and mortality. The objective of the current study is to evaluate the effect of patient insurance status on outcomes following shoulder replacement surgery.

METHODS Data was obtained from the Nationwide Inpatient Sample between 2004 and 2011. Analysis included patients undergoing shoulder arthroplasty procedures determined by ICD-9 procedure codes. Patient demographics and comorbidities were analyzed and stratified by insurance type. The primary outcome was medical and surgical complications occurring during the same hospitalization with secondary analysis of mortality. Pearson's chi¬squared test and multivariate regression were performed.

RESULTS A data inquiry identified 103,290 patients (68,578 Medicare, 27,159 private insurance, 3,544 Medicaid/uninsured, 4,009 Other) undergoing partial, total and reverse total shoulder replacements. The total number of complications was 17,810 (17.24%), and the top three complications included acute cardiac events (8,165), urinary tract infections (3,154), and pneumonia (1,635). The highest complication rate was observed in the Medicare population (20.3%), followed by the Medicaid/uninsured (16.9%), other (11.1%), and the privately-insured cohort (10.5%). Multivariate regression analysis indicated that having Medicare insurance, white race, increasing age, higher comorbidity, and urgent or emergent admissions was associated with medical complications. Black patients, increasing age and comorbities was associated with surgical complications. Overall mortality was 0.20% and was more common in total shoulder arthroplasty and surgeries done on emergent or urgent admissions.

DISCUSSION This data reveals that patients with Medicare, Medicaid or no insurance were more likely to have medical complications, most commonly cardiac complications, UTIs and pneumonia. Primary insurance payer status can be considered as an independent risk factor during preoperative risk stratification and planning.


The Si content dependences of the magnetic properties of the Fe82.65Cu1.35SixB16−x alloys prepared by melt spinning were studied. The maximum Bs and minimum Hc were observed at around x=2 for the annealed Fe82.65Cu1.35SixB16−x alloys. The Bs and Hc of the annealed Fe82.65Cu1.35Si2B14 alloy were 1.84T and 6.5A∕m, respectively. The average grain size of the bcc Fe nanocrystal in the annealed alloys with x⩽2 was about 20nm, it increased with x at x>2. The annealing temperature range without the precipitation of o-Fe3B expanded with Si content.


For disadvantages of wiring difficult,incomplete network coverage because of using wire transmission and high cost because of independent of monitoring networks exited in underground monitoring and control system,a design scheme of underground multi-media monitoring and control system based on DM365 was put forward.The system uses DM365 video processing chip as hardware platform,embedded Linux as software platform,and integrates wireless data transmission of sensor and video monitoring,which can monitor data of underground video,equipment working conditions,gas concentration,humidity,temperature and other multidimensional environment information.The experiment result shows that the system improves video image processing capabilities,meets with requirements of the underground wireless transmission distance,and is suitable for use in a limited energy of coal mine.


R AY Bradbury's The Martian Chronicles is a provocative study in literature. Because of its timeliness, it generates interest. The present-day student is challenged by and believes in the colonization of the planets. He is concerned with the problems of the American, and Bradbury is obviously dealing with American problems: inequality, ecology, materialism, war. Since the student is vitally interested in Bradbury's message, he is eager to explore the literary techniques by which Bradbury conveys his message: satire, paradox, poetry, and symbolism. The Martian Chronicles really has no central plot; some chapters were written as short stories and published before the book as a whole; however, it has a central theme, the colonization of Mars. Each chapter is complete and can be read as a short story. They are arranged in chronological order as various expeditions from Earth, and although there is no main plot development, the story of each expedition carries its own plot. The stories are fascinating fantasies, full of color, related in pure poetry. Sometimes they are rather difficult to understand and leave the reader wonder-


Empowered engineers in an inherently unstable workforce are better able to remain internally stable in an externally unstable work environment. These engineers are likely to be more creative and productive, enhancing their net contribution to engineering through their careers. The purpose of this study is to evaluate the perceptions which engineering students bring with them to an introductory electrical engineering course before they embark on their technical degree pathway. This study examines how empowered the student feels at the start of the course and how their self-perceptions may affect their performance in the class. This study is part of a larger investigation, evaluating the impact of shifting the defining metrics for success from external to internal factors on the engineering student's performance and sense of fulfillment in the classroom

The educational institution's digital certification In the current scenario of digital certification with a digital signature, a blockchain technology server is utilized. There is a chance of updating or creating phony certificates in order to prevent the organization's use of digital certification in the future. By enabling tamper-proof data storage, this blockchain technology will prevent server hacking and data modification. In order to prevent counterfeiting in blockchain technology offers the electronic data file that is formed in the ledger using the hash function it tampers with. A secured, unchangeable, authenticated certificate is produced by this method. In the transparent network, a document that has been digitally signed and approved by peers is exchanged. They are granted these certifications. The blockchain is attracting intense media and scientific interest while igniting interest in its possible applications and function in promoting social decentralization [9] and independence from centralized authorities. The impact that the widespread use of this technology will have on our societies, both positively and negatively, has received a lot of attention. Despite all of this thought, there isn't much literature that addresses the issues it might present, except for technological ones. The introduction of blockchain can be likened to the development of the Internet, demonstrating the potential for profound changes in a variety of industries. Although, in accordance with presented a first analogous example of this technology.Finally, the system will use smart contracts to automate processes and ensure data accuracy. Smart contracts are self-executing programs that are stored on a blockchain and can be used to facilitate transactions and agreementsbetween two parties, without the need for a third party. Smart contracts will ensure that the data is accurate and up to date, as well as provide an additional layer of security. This will ensure that the transactions are secure and can be verified by anyone on the network.


The Armed Police Force s an important component in defending national security and maintaining social stability under the leadership of the Party.Combating crime in accordance with the law,protecting the people's fundamental interests and safeguarding the social stability are the fundamental duties of the Armed Police Force.In order to adapt to the development of the state's and the armies' legal system's construction,enacting the Law of Chinese People's Armed Police Force based on connecting the leadership system,functions and mandates of the Armed Police Force,is of great and far-reaching significance.Being guided by some related domestic laws,learning from foreign experience in the relevant legislation,using the constantly improved legislative technologies,and strengthening the legislative norms,enacting the Law of Chinese People's Armed Police Force is of great feasibility.


This paper presents results from an exploratory, mixed methods study on the integration of research and practice in the social work curriculum. A web-based survey was used to collect data from 184 social work research instructors. Seventy-eight percent of instructors reported that their programs integrated practice content in research courses, particularly at the BSW level. In contrast, about half of instructors reported that research content was infused in other courses, with less integration reported in MSW programs. Qualitative findings consistent with Siegel's typology for research and practice integration include the use of research activities as clinical interventions, as a way to shape interventions, and as a problem-solving process for practice. The implications for social work education are discussed.


Objective:To investigate the proliferation-inhibiting and apoptosis-inducing activity of mimics of manganese superoxide dismutase(MnSODm) on human multidrug-resistant leukemia cell line K562/ADM in vitro.Methods:Human multidrug-resistant leukemia cell line K562/ADM over-expressing mdr1 gene was used as the target cells.The cell proliferating activity was assessed with a MTT colorimetric assay.The morphology of K562/ADM cells was observed with optical,fluorescent and electronic microscopy,and apoptosis was explored by double staining of FITC-Annexin V and propidium iodide(PI).Results:MnSODm(1-50 mg/L) obviously inhibited the proliferation of K562/ADM cells in a manner depending on both dose and time(P0.01).The cells treated with MnSODm showed the typical apoptotic morphological changes.The apoptotic rate of MnSODm-treated K562/ADM cells assed with Annexin Ⅴ/PI staining was greatly increased from 3.32% to 13.91% and 55.0% after exposure to 10 mg/L and 50 mg/L for 48 hours.Conclusion:MnSODm greatly inhibits the proliferation of drug-resistant K562/ADM cells,and induces apoptosis of K562/ADM cells in vitro.


In research of Optimization of performance of wireless sensor networks to improve anti-attack capability, key management is an important security issue to be solved. Due to the severe restriction on resources and work environment, the classic key distribution algorithms are not suitable for wireless sensor networks. Aiming to improve the capability of security and feasibility of wireless sensor networks, after considering the issues of network security, traffic problems, memory problems and computational complexity problem, this paper proposes a key management scheme based on grouping within cluster to solve the problem of poor salability, low work efficiency and communication times . This scheme makes a big improvement of group key generation method. Cluster heads and group heads in the clusters are respectively used to generate and distribute keys via secure channels in each group. The simulation results show that this scheme further improves network's ability to resist DOS (denial of service) attack, reduces the energy consumption and time consumption in key negotiation and improves the survival time and efficiency of entire network.


The Borg Multiobjective Evolutionary Algorithm (MOEA) is a new, efficient, and robust optimizer that outperforms competing optimization methods on numerous complex engineering problems. To date, the Borg MOEA has been successfully applied to problems ranging from aerospace applications to water resources engineering. Problems from these domains often involve expensive design evaluations that require large-scale parallel algorithms to produce results in a reasonable amount of time. This study presents the first theoretical and experimental look at parallelizing the Borg MOEA. First, we derive theoretical models for predicting speedup, efficiency, and processor count lower and upper bounds. Second, we validate these models on a simple problem, DTLZ2, and a harder, non-separable problem, UF11. Third, we examine the effects of scaling on convergence speed and solution quality. These experiments are performed on the 62, 976 core Texas Advanced Computing Center (TACC) Ranger system.


Recent reports suggest that genes encoding resistance to major classes of antibiotics existed long before development and use of such drugs. For


In the discussion of the Korean social policy development, we have much interest in the relationship between the economic development and the Korean National Pension System (KNPS onwards) development. For example, the 1973 Act (the act related to introduction of the KNPS) showed that the KNPS was designed to contribute to the economic development, while the 1986 Act (related to the establishment of the KNPS) resulted from the economic development. This paper argues that the introduction of the KNPS in 1973 was doomed to fail because even though the stage of issue flow was in social issue, the government tried to raise this social issue (the introduction of the KNPS in 1973) to the stage of government issue for the purpose of domestic capital mobilization. On the other hand, the reason why the establishment of the KNPS in the form of funded system in 1986 was successful derives from the stage of issue flow. In other words, at that time, the elderly problem was in normal government issue.


Background: BCR-ABL1 negative chronic myeloproliferative neoplasms (CMPNs) are a heterogeneous group of clonal hematological malignancies. In last years, some genetic alterations have been described to cause these diseases, most of them activating tyrosine kinase (TK) genes. Tyrosine kinases proteins have an important role in cell growth and oncogenesis. Gain-of-function mutations in TK genes can produce a constitutive activation of several signaling pathways. Aims : In this study, we study the EGFR gene that codes for a tyrosine kinase receptor (RTK) involved in signaling pathways relevant in hematological cells. Mutations in this gene have been found involved in lung cancer, and it could have an important role in the pathogenesis of hematological disorders. Methods: We have analyzed the transmembrane and TK-coding domains of EGFR by dHPLC to detect mutations on samples from 44 BCR-ABL1 negative / V617F JAK2 negative CMPN patients and 20 control samples from healthy individuals. Results: Our results show that this gene is not frequently mutated in CMPNs. Conclusion : The EGF Receptor gene does not appear to be involved in the pathogenesis of the myeloproliferative neoplasms. This work has been funded with the help of the Institute of Health Carlos III (FIS PI040037), Spanish Ministry of Science and Innovation (SAF 2007-62473), the PIUNA Program of the University of Navarra and the Caja Navarra Foundation through the Program "You choose, you decide" (Project 10830).


In the finite-dimensional Euclidean space, a task of pursuing two evaders by a group of pursuers is considered, described by a system of the form D(α)zij=azij+ui−v, where D(α)f is the Caputo fractional derivative of order α∈(0,1) of the function f, and a is a real number. It is assumed that all evaders use the same control and that the evaders do not leave a convex cone with vertex at the origin. The aim of the group of pursuers is to capture two evaders. The pursuers use program counterstrategies based on information about the initial positions and the control history of the evaders. The set of admissible controls is a unit ball centered at zero, the target sets are the origins. In terms of initial positions and game parameters, sufficient conditions for the capture are obtained. Using the method of resolving functions as a basic research tool, we derive sufficient conditions for the solvability of the approach problem in some guaranteed time

A laboratory study of the effects of oriented pennyshaped inclusions embedded in a solid matrix on the propagation of seismic shear waves shows good agreement with theoretical predictions for some polarizations and poor agreement for polarizations at large crack densities. The models are constructed of solid matrix of epoxy resin with inclusions of thin rubber discs of approximately equal cross-sectional areas. The theoretical basis for these experiments is the theory of Hudson, in which the wavelength is greater than the dimensions of the individual cracks and their separation distance, and the cracks are in dilute concentration. By a pulse transmission method, seismograms were gathered in models free of inclusions and models with inclusions. Seismic measurements of velocity anisotropy, for variations in both a polarization and propagation direction, were performed on physical models with inclusions (cracks) representing five different crack densities (1, 3, 5, 7, and 10 percent). Variations in velocity ...


The present invention provides a polishing composition for a glass substrate having a pH of from 1 to 5 and containing silica particles having an average particle size of from 5 to 100 nm, wherein, in a projected image of the silica particles obtainable by an image analysis of electron photomicrographs, an average of an area ratio R of a projected area of the silica particles (A1) to an area of a maximum inscribed circle of the silica particles (A), i.e. (A1/A), is in the range of from 1.2 to 3.0, and the silica particles have an average of 2.0 to 10 projection portions having a curvature radius of from f to ½ of a radius of the maximum inscribed circle of the silica particles (r) on the outline of the silica particles in the projected image, and a method for manufacturing a glass substrate, including the step of polishing a substrate to be polished with a polishing load of from 3 to 12 kPa and at a pH of from 1 to 5 while allowing the polishing composition to be present between a polishing pad and the substrate to be polished. The polishing composition for a glass substrate of the present invention can be suitably used, for example, in the manufacture of glass hard disks, aluminosilicate glass for reinforced glass substrates, glass ceramic substrates (crystallized glass substrates), and the like.


To the Editors: Insufficient sleep can adversely affect selective components of the executive function system while leaving others relatively intact. Planning and sequencing abilities comprise crucial components of executive functioning, allowing an individual to hold several pieces of information in working memory, manipulate that information to consider possible outcomes, and implement an appropriate sequence of actions to achieve a desired goal state. To date, such capacities have only been minimally explored in the context of sleep deprivation, although preliminary work suggests that they may be adversely affected by sleep loss. Even less work has explored the effectiveness of stimulants such as caffeine, a widely consumed methylxanthene that is believed to block A1 and A2 adenosine receptors in the brain, in sustaining these abilities during prolonged periods of sleep deprivation. To examine whether repeated moderate doses of caffeine would effectively sustain performance on the Tower of London (TOL), a classic test of visuospatial planning and sequencing that is mediated extensively by the dorsolateral prefrontal cortex, 24 healthy participants underwent 3 nights of sleep deprivation in a laboratory setting (19 men; 5 women; mean age, 25.4 [SD, 4.2] years). Data pertaining to risk taking and moral judgment tasks from this same sample have been reported elsewhere in prior publications. Participants were excluded for regular tobacco use or caffeine consumption exceeding 300 mg/d and abstained from caffeine for 24 hours before the study (verified by urine drug screening). Written informed consent was obtained, and participants were financially compensated for their time. This study was approved by the Walter Reed Army Institute of Research Human Use Review Committee and the US Army Human Subjects Research Review Board. Participants slept overnight in the laboratory from 11 PM until 7 AM the following morning and then remained awake for the next 77 hours. A double-blind administration of either 200 mg of caffeine (n = 12) or placebo (n = 12) was given every 2 hours from 1 AM through 7 AM during each of the 3 nights of sleep deprivation (ie, 800 mg total per night), dispensed in chewing gum (Stay Alert Gum). Each morning, from 10:45 to 11 AM (ie, after 4, 52, and 76 hours awake), participants completed a 10-trial computerized version of the TOL (Colorado Assessment Tests, http://www.catstests.com), which involved rearranging beads on 3 pegs to match a target goal arrangement. Four dependent variables were collected: (1) total movesVthe sum of all bead placements made to complete the entire task (minimum possible = 55 moves); (2) time to first moveVthe mean time between presentation of each new trial and the first bead movement for that trial; (3) average move timeVthe mean number of seconds taken to complete each move across the task; (4) throughputVan index of the number of correct bead placements made per minute (ie, [(proportion of correct moves) / (average move time)] 0.60), assuming that the proportion of correct moves = (the minimummoves possible, ie, 55) / total moves). For total moves taken to complete the TOL, there was no significant main effect of caffeine (F1,22 = 0.72, P = 0.42) or session (F2,44 = 1.48, P = 0.24) and no drug session interaction (F2,44 = 0.46, P = 0.64) (Fig. 1A). For time to first move, there was a main effect of drug (F1,22 = 6.92, P = 0.015), session (F2,44 = 5.13, P = 0.01), and a drug session interaction (F2,44 = 4.56, P = 0.016) (Fig. 1B), which was driven by faster performance in the caffeine group at 52 (P = 0.003) and 76 (P = 0.023) hours of sleep deprivation compared with the placebo group. For average move time, there was a main effect of drug (F1,22 = 8.33, P = 0.015), session (F2,44 = 5.31, P = 0.02), and a drug session interaction (F2,44 = 3.86, P = 0.047) (Fig. 1C). This interaction was driven by faster average bead placement in the caffeine group at 52 (P = 0.005) and 76 (P = 0.008) hours of sleep deprivation compared with the placebo group. In terms of the number of correct bead placements per minute, or throughput, there was a main effect of drug (F1,22 = 13.87, P = 0.001), session (F2,44 = 4.93, P = 0.012), and a drug session interaction (F2,44 = 3.21, P = 0.05) (Fig. 1D). This interaction was driven by a greater number of correct bead placements per minute for the caffeine group at 52 (P = 0.002) and 76 (P = 0.005) hours of sleep deprivation compared with the placebo group. The caffeine group also demonstrated enhanced throughput at 52 (P = 0.002) and 76 (P = 0.015) hours of sleep deprivation, compared with their own baseline performance, whereas the placebo group showed no significant change. During 3 nights of total sleep deprivation, moderate doses of caffeine significantly improved planning speed, average response time, and throughput efficiency on the TOL compared with placebo. Furthermore, the caffeine group showed enhancement of throughput during sleep deprivation relative to baseline performance, most likely due to sustainment of learning via task practice across sessions, an outcome that was absent for the placebo group. On the other hand, caffeine was ineffective at improving the overall number of moves required to solve the puzzles compared with placebo, suggesting that the throughput improvements resulted primarily from greater speed and per-move efficiency rather than to enhanced global economy of the solutions. Prior research suggests that the effect of caffeine on executive functions during sleep deprivation is particularly complex. Whereas caffeine has been reliably shown to restore simple alertness, psychomotor vigilance, and motor learning 11 during sleep deprivation, it has proven less consistent at sustaining performance on some more complex executive function tasks that rely heavily upon prefrontal cortex systems, including minimizing rule violations and stereotypy during random number generation; risk-based decision making; estimation of quantities, weights, times, and distances; verbal fluency; color-word interference; or mental set shifting. However, under certain conditions, caffeine has been shown to have an advantageous effect for restoring sleep-deprived performance on other tasks that purport to tap into specific prefrontal executive control systems, such as the Tower of Hanoi 2 and the Balloon Analog Risk Task, suggesting that caffeine may affect some underlying systems involved in such complex tasks.

AbstractThe role of surface friction on shallow nonprecipitating convection is investigated using a series of large-eddy simulations with varying surface friction velocity and with a cloud identification algorithm. As surface friction intensifies, convective rolls dominate over convective cells and secondary overturning circulation becomes stronger in the subcloud layer, thus transporting more moisture upward and more heat downward between the subcloud and cloud layers. Identifying individual clouds, using the identification algorithm based on a three-dimensional topological analysis, reveals that intensified surface friction increases the number of clouds and the degree of tilting in the downstream direction. Highly intensified surface friction increases wind shear across the cloud base and induces cloud tilting, which leads to a vertically parabolic profile of liquid water mixing ratio instead of the classical two-layer structure (conditionally unstable and trade inversion layers). Furthermore, cloud ti...

The goal of this work is to simulate the techniques of a scratch DJ (turntablist) by designing and building a mechanism to manipulate a record and by creating software to intelligently command the mechanism. The long term goal of the project is to create a completely autonomous system that will be able to compose and perform scratch routines comparable to those of the best human DJ's. The metric of success for the work performed for this thesis will be its ability to simulate human attributes. This thesis will discuss the construction of a mechanical system that will manipulate records in ways similar to those of a human scratch DJ, the integration of hardware and software to accurately control the mechanical system, and the design and implementation of software to record the motions of a human scratching a record, to play a tune on a record of a constant note by varying the playback speed, to pick beats out of a piece of previously recorded music, and to integrate these into a performance interface. Many scratch DJ's use volume controls to enhance their musical compositions. This technique is not in the scope of this project. Additionally, DJ's switch records during the course of a performance, but this project will not include such functionality. Furthermore, the mechanical component of the project is built around the industry standard Technics SL-1200 M3D model turntable. Other turntable models are not supported by this project.

PERHAPS no part of the health care system generates as much dissatisfaction as the organization and financing of long-term care for the elderly. The disabled elderly and their families confront a fragmented delivery and financing system, a relative lack of noninstitutional services, long waiting lists for institutional placement, mediocre care and financial hardship.1 Paradoxically, public financing, primarily through Medicaid, is perceived as both overly expensive and yet resulting in an inadequate system. The long-range demographics of the elderly will increasingly strain this imperfect system. The aging of the baby boom population combined with falling mortality rates for the aged suggest a sharply increasing demand for long-term care which will require substantially greater public and private expenditures. Projections of current age/sex specific nursing home utilization rates suggest four times as many persons in nursing homes in 2040 as in 1980.2 The large increase in need presents both a problem and an opportunity for reform. Fundamental policy questions must be addressed if we are to do better in the future than we are doing now. Is there a better way to organize the delivery system than merely making the current system a lot larger? Will "society" be willing to pay for the current system multiplied by three or four? Is there a better way to finance care? This paper will provide a very preliminary report on a project that Alice Rivlin and I are conducting at the Brookings Institution that attempts to an-


The article focuses on the study of grammatical and syntactic peculiarities of translation of English user manuals for household appliances. The study of the instructional text through the prism of linguistics and translation studies is relevant research, since the instruction is directly related to the high-tech process that causes the emergence of new products. This scenario requires further study of the phenomenon. The purpose of the article is to analyze the use of transformations in translation of English user manuals for household appliances into Ukrainian at the grammatical and syntactic levels. The object of the research is the text units of English and Ukrainian user manuals. The study is based on the user manuals for household appliances of such companies as Beko, Indesit, and Philips. During the study, the characteristic grammatical and syntactic peculiarities of the user manuals for household appliances were analyzed. The result of the study is the identification of the most common means of translation of the above-mentioned features. When translating user manuals into Ukrainian, literal translation is mostly often used. Syntactic permutation and sentence fragmentation are most frequently used next. Less frequent way of translating is sentence integration. Moreover, it was found that among the grammatical transformations, the most common are addition, omission and change of a part of speech.
Keywords: grammatical features; syntactic features; translation transformations; translation methods; user manuals.

Abstract A novel coordination polymer, [Pb(L)(1,3-bdc)]·2H2O (1), (L = 2-(2,6-dichlorophenyl)-1H-imidazo[4,5-f][1,10]phenanthroline, 1,3-H2bdc = 1,3-benzenedicarboxylic acid) has been successfully prepared under hydrothermal conditions. The structure of 1 is a 1D chain structure, which further stacks together to form a 3D supramolecular architecture by π–π interactions and C–H⋯π interactions. In addition, the thermogravimetric analysis of 1 has been investigated.


The optimization problems, such as scheduling or project management, in which the objective function depends on the operations maximum and plus, can be naturally formulated and solved in max-plus algebra. A system of discrete events, e.g., activations of processors in parallel computing, or activations of some other cooperating machines, is described by a systems of max-plus linear equations. In particular, if the system is in a steady state, such as a synchronized computer network in data processing, then the state vector is an eigenvector of the system. In reality, the entries of matrices and vectors are considered as intervals. The properties and recognition algorithms for several types of interval eigenvectors are studied in this paper. For a given interval matrix and interval vector, a set of generators is defined. Then, the strong and the strongly universal eigenvectors are studied and described as max-plus linear combinations of generators. Moreover, a polynomial recognition algorithm is suggested and its correctness is proved. Similar results are presented for the weak eigenvectors. The results are illustrated by numerical examples. The results have a general character and can be applied in every max-plus algebra and every instance of the interval eigenproblem.


Nowadays on E-commerce platforms, products are presented to the customers with multiple modalities. These multiple modalities are significant for a retrieval system while providing attracted products for customers. Therefore, how to take into account those multiple modalities simultaneously to boost the retrieval performance is crucial. This problem is a huge challenge to us due to the following reasons: (1) the way of extracting patch features with the pre-trained image model (e.g., CNN-based model) has much inductive bias. It is difficult to capture the efficient information from the product image in E-commerce. (2) The heterogeneity of multimodal data makes it challenging to construct the representations of query text and product including title and image in a common subspace. We propose a novel Adversarial Cross-modal Enhanced BERT (ACE-BERT) for efficient E-commerce retrieval. In detail, ACE-BERT leverages the patch features and pixel features as image representation. Thus the Transformer architecture can be applied directly to the raw image sequences. With the pre-trained enhanced BERT as the backbone network, ACE-BERT further adopts adversarial learning by adding a domain classifier to ensure the distribution consistency of different modality representations for the purpose of narrowing down the representation gap between query and product. Experimental results demonstrate that ACE-BERT outperforms the state-of-the-art approaches on the retrieval task. It is remarkable that ACE-BERT has already been deployed in our E-commerce's search engine, leading to 1.46% increase in revenue.


. Agricultural irrigation is an important factor affecting the development of agricultural drought, which is not showed in the Palmer Drought Severity Index (PDSI). In this work, the water balance model in PDSI has been modified by adding irrigation items, which improves the accuracy of the calculation results of the model and shortens the calculation time step. The modified Palmer Drought Severity Index (M_PDSI) is constructed by using daily weather data and irrigation data from 1985-2012 in the study area. Weekly indices cumulated in each growth stage are used for the implementation of crop models by a linear multiple regression model. The crop yield models are evaluated to determine a more appropriate agricultural drought index between M_PDSI and PDSI by comparing the predicted yields to the observed yields. By comparing the development of agricultural drought, it can be seen that the M_PDSI can improve the sensitivity to the dynamic change of soil wet and dry in short-term, and the development process of drought is more in line with the actual situation; by comparing the fitting test results of the predicted yields, it can be seen that, the M_PDSI ranks better than the PDSI in all four goodness-of-fit measures, M_PDSI is proved to be more suitable than PDSI for evaluating agricultural drought.

Cleaning and shaping of the root canal system are essential for the successful outcome of endodontic treatment. In addition to the routinely used irrigating solutions, other technologies have been investigated for the treatment of root canal dentine, such as different types of laser systems. Purpose: The aim of our in vitro study was to evaluate the effect of different types of laser irradiation (Er:YAG , Nd:YAG, diode laser and photodynamic therapy) on the intracanal dentin and their interference in the apical seal of filled root canals. Methodology: 72 human single rooted teeth were randomly assigned into 6 groups. Root canal preparation was done using ProTaper Universal rotary system up to F3. The laser irradiation was performed at the end of the traditional endodontic preparation as a final means of decontaminating the endodontic system. Teeth were filled with a core-carrier system Guttacore (Dentsply, Sirona) and sealer AH- plus. Results: Statistical analysis showed that all groups had significantly less leakage in apical third than the control group. The laser-treated groups presented better results than Group II (Classical disinfection protocol), without statistically significant difference. The morphological changes on the apical intraradicular dentin surface caused by Nd:YAG and Er:YAG laser irradiation resulted at least linear dye apical leakage. Conclusions: Laser irradiation may improve the apical seal of the root canal. Different type of laser systems with appropriate parameters are recommended to be used as an adjunct to the current chemical root canal disinfection protocols.


We report on the progress of the new NSLS timing system. There are three types of requirements for NSLS timing system: clocks, synchronization and trigger circuits. All ring revolution frequency clocks are generated using ECL and high speed TTL logic. The synchronization circuits allows to fill both storage rings with any bunch pattern. The triggers are generated by using commercially available digital delay generators. The delay unit's outputs are ultrastable, with a resolution of 5 ps, and are programmed by computer via IEEE 488 interface. The block diagrams, description of all major timing components and the present status are provided in this paper.

The sense of social responsibility is a personality required by college students. Values in the new period of diversified form have positive and negative influence on college students' social responsibility. College students' sense of social responsibility is not a spontaneous process. It must be achieved through careful education, scientific training and cultivate training. The basic rules of social responsibility of college students are the formation of leading values of college students with the socialist core value system; condense positive energy family, school, society education; fully play a role in self-education of university students.


A new mechanical approach is presented in this paper for modeling the system of Inverted Elastic Pendulum on Cart with Tip Mass (IEPCTM) exhibiting multiple dynamic equilibria. Torsional spring is assumed in the system structure to account the flexibility of pendulum. The condition of existence of multiple equilibria dynamically is also incorporated in this model. Mathematical model is framed using Euler-Lagrange analysis. Validation of proposed model is accomplished through comparison of simulation results with experimental data from actual plant behavior. Simple modeling idea & approach, ease in model reproducibility & simulation and simplicity from implementable control design perspective form the key features of the proposed IEPCTM system model in this work.


All over the world, deterioration of environmental quality has been considered as a hot issue. The growing number of industries is one of the major reasons for the enhanced level of pollution and fast degradation of environmental resources. This situation urges the corporates to involve themselves in socially responsible activities and to periodically assess the ecofriendly technologies. This paper proposes to investigate the Environmental Kuznets Curve Hypothesis, with reference to sample companies listed in BSE S&P – 500, over the period 1st April 2005 to 31st March 2014. In order to determine the existence of EKC relationship, the sign and magnitude of regression coefficients were analyzed. The results exhibited U shaped relationship for ROE, ROCE, and ROS. At the same time, EKC relationship, by way of inverted U shaped curve, was found for ROA. Based on the empirical findings of this study, some suggestions have been put forward to the corporates and policy makers, to control the level of energy intensity, by implementing eco-friendly technologies.


The interaction of anionic silica nanoparticles (Ludox LS30) and non-ionic surfactants decaethylene glycol monododecylether (C12E10) without and with anionic sodium dodecyl sulfate (SDS) in aqueous electrolyte solution has been studied by small-angle neutron scattering (SANS). The measurements have been carried out for fixed concentrations of nanoparticle (1 wt%), surfactants (1 wt%) and electrolyte (0.1 M NaCl). Each of these nanoparticlesurfactant systems has been examined for different contrast conditions where individual components (nanoparticle or surfactant) are made visible. It is observed that the nanoparticle-C12E10 system leads to the depletion-induced aggregation of nanoparticles. The system however behaves very differently on addition of SDS where depletion interaction gets suppressed and aggregation of nanoparticles can be prevented. We show that C12E10 and SDS form mixed micelles and the charge on these micelles plays important role in tuning the depletion interaction.

In the last one hundred years or so, China has been through three major revolutions: the 1911 Revolution, the Nationalist Revolution in the 1920s, and the Communist Revolution. Although these revolutionary movements differ from each other in nature, objectives, forms, destructiveness, and results, each succeeded in changing the status quo of the Chinese nation-state. The overall trajectory of the three revolutions shows an increasing level of popular participation, social destructiveness, and violence. In some ways, the objective of the 1911 Revolution was to overthrow the Manchu monarch and restore power and authority to the Han people. Inspired by Western concepts of constitutionalism and democracy, this revolution succeeded in ending dynastic rule and replacing it with a republican form of government. But the revolution failed to address urgent social problems confronting the masses at the time. As a result, the level of popular participation in this revolution was low, and the extent of violence was also limited. The Nationalist Revolution was inspired by socialist ideologies and the Russian Revolution— both of which had Western origins as well. The primary goals of this revolution were abolishing unequal treaties, achieving national sovereignty and independence, ending warlord rule, and bringing about national unification. Promoting social equality and helping the poor were also on the agenda of this revolution. Consequently, the level of popular participation in this revolution was much higher than it had been during the 1911 Revolution. However, when compared with the Communist Revolution, the Nationalist Revolution attracted mostly intellectuals and those in the middle strata of society. The vast majority of the lower social strata were largely left out of the process, which explains the relatively low level of social destruction during the Nationalist Revolution. In contrast, the Communist Revolution focused on social reform and improving the living conditions of the most impoverished classes. This emphasis, combined with a nationalist agenda, allowed the Communist Revolution to mobilize the broadest possible participation from all social strata. In so doing, it unleashed an enormous amount of energy, produced an unprecedented level of destruction, and gave birth to a state whose power and ability to exercise control over society are unrivaled. In underdeveloped nations, revolutionary success usually promotes citizens' identification with the new nation-state and heightens their nationalist consciousness. However, the people's desire and ability to identify with the new nation-state vary greatly, depending on the revolution's success in mobilizing the masses and on the level of popular participation in the revolution. During the late Qing period, few intellectuals had a true sense of nationalism. Many young people at that time developed a sense of national


Perceptual learning is defined as fast improvement in performance and retention of the learned ability over a period of time. In a set of psychophysical experiments we demonstrated that perceptual learning occurs for the discrimination of direction in stochastic motion stimuli. Here we model this learning using two approaches: a clustering model that learns to accommodate the motion noise, and an averaging model that learns to ignore the noise. Simulations of the models show performance similar to the psychophysical results.

The article is devoted to the socio-philosophical and religious studies analysis of the charitable activities in Islam. The subject of the research is the theological foundations of caritative activity in Islam. The mechanism of interfaith interaction in the field of charity is considered on the example of the Vladimir Mukhtasibat of the Central Spiritual Directorate of Muslims of Russia. Recommendations for the creation of applied strategies in the field of caritative partnership are given. The modern policy of the state is aimed at the implementation of interfaith interaction, including the interaction of religious organizations with government authorities. At the present time, the norms of socio-caritative relations between religious organizations and the state are mostly declared, definitions are generalized and are unable to concretize most of the interaction mechanisms. The key to the successful functioning and development of caritative activity is the equality of religious organizations and the absence of priority spiritual directions for state bodies when building a policy of caritative interaction.


O‐Fucosylation is a post‐translational glycosylation in which an O‐fucose is covalently attached to the hydroxyl group of a specific serine or threonine residue. This modification occurs within the consensus sequence C2X4−5(S/T)C3 present on epidermal growth factor‐like repeats of several proteins, including the Notch receptors and their ligands. The enzyme responsible for the addition of O‐fucose to epidermal growth factor‐like repeats is protein O‐fucosyltransferase 1. Protein O‐fucosyltransferase 1‐mediated O‐fucosylation is essential in Notch signaling, folding and targeting to the cell surface. Here, we studied the expression pattern of protein O‐fucosyltransferase 1 in cattle and showed that the active enzyme is present in all tissues examined from embryo and adult as a glycoprotein with two N‐glycans. By comparing protein O‐fucosyltransferase 1 sequences available in databases, we observed that mammalian protein O‐fucosyltransferase 1 enzymes possess two putative N‐glycosylation sites, and that only the first is conserved among bilaterians. To gain more insight regarding the significance of N‐glycans on protein O‐fucosyltransferase 1, we substituted, by site‐directed mutagenesis, bovine protein O‐fucosyltransferase 1 N65, N163 or both, with L or Q. We demonstrated that the loss of N‐glycan on N163 caused a slight decrease in protein O‐fucosyltransferase 1 activity. In contrast, glycosylation of N65 was crucial for protein O‐fucosyltransferase 1 functionality. Loss of glycosylation at N65 resulted in aggregation of protein O‐fucosyltransferase 1, suggesting that N‐glycosylation at this site is essential for proper folding of the enzyme.


Smartphones are one of the most widely used cell phones in the United States today. They perform multiple functions, and in April 2009, another capability was added to that list. Smartphones are now able to display sonographic images of the human body and organs through use of a smartphone-compatible ultrasound probe. The probe can be plugged into the USB slot of a smartphone and used to allow gray-scale image visualization. This article discusses the function and structure of this new and emerging technology while looking at the impact of this technology on the field of sonography.


Social cognition is the study of how people make sense of themselves and others. Impairment in several domains of social cognition is increasingly being recognized in Parkinson's disease (PD).


The metaphor of "teaching as art" has been lasting for a long time. However, in comparison with the scientific inquiry of teaching, the inquiry based on the perspective of art is just rising in recent years. In the approach of "curriculum as aesthetic text," many researchers attempted to seek for the meanings of curriculum and teaching through clarifying traits of art processes. Following the approach, this article aims to discuss how artists think and act and furthermore identify the similarities betweens teaching and art by means of interviewing some teachers with rich experiences of art creation.There are four main findings based on the data from the interviews. Firstly, both artist and teacher intend to convey their viewpoints to people, even influence people and society. However, the intention is stronger in teaching than art. Secondly, art welcomes flexible purposing and emergence, and likewise the excellent teaching doesn't exclude the emergence and flexibility. Thirdly, in both art and teaching, while logical thinking functions to the composition of work, imagination, intuition and associative thinking make work dynamic and amazing. Fourthly, a valuable innovation is to find the appropriate ways to express ideas, but not to just be distinguished from others. To pursue innovation, teachers should usually try and record a wide variety of materials and methods and understand their features as artists do.Artistic teaching demands teachers to keep open-minded, to observe, try and record the things and phenomenon around, to search for possibilities, and to seek the new self.


Skin wounds of guinea pigs were locally exposed to 750-r doses of x rays at various times after wounding to inhibit cellular proliferation in attempts to determine the origin of cells involved in wound repair. Cellular proliferation was followed by the incorporation of thymidine-H³ as seen by autoradiography. It was concluded that the effect on fibroblast proliferation resulted from influences applied to cells resident in the tissues of the wound area at the time of wounding. A large proportion of fibroblasts would seem to originate from cell precursors present in resting local mesenchymal tissues. Opposing previous theory, in the present experiment no excessive proliferative attempts by fibroblasts were observed adjacent to nonproliferating capillaries. Thus, while capillary inhibition did occur, and it is probable that, in time, fibrous precipitation might result locally from the activity of arrested fibroblasts, there was no evidence to suggest a limitation of recruitment from the vascular system in the area as a result of irradiation effect on capillaries.

The prediction of the stress distribution in the powder bed is important for the design of the storage vessel and the unit operation of the powder. We calculated the stress distributions in a plane stress field by using the constitutive equation of powder based on the plastic potential and Coulomb-Mohr criteria, and the incremental finite element method.We also measured the wall stress distributions and compared them with the calculated results. They agree with each other in the horizontal stress distribution of the side wall as well as in the vertical stress of the bottom. Hence, the constitutive equation and our simulation method are reasonable and would be useful for the design of the powder storage vessel.

Thanks to the Academic Senate's Open Access Policy, a great many UC-authored scholarly publications will now be freely available on this site. Let us know how this access is important for you. We want to hear your story! Abstract: A current limitation of MR spectroscopic imaging of multiple skeletal muscles is prolonged scan duration. A significant reduction in the total scan duration using the echo-planar correlated eScholarship provides open access, scholarly publishing services to the University of California and delivers a dynamic research platform to scholars worldwide. spectroscopic imaging (EP-COSI) sequence was accomplished using two bipolar readout trains with different phase-encoded echoes for one of two spatial dimensions within a single repetition time (TR). The second bipolar readout was used for spatially encoding the outer k-space, whereas the first readout was used for the central k-space only. The performance of this novel sequence, called multi-echo based echo-planar correlated spectroscopic imaging (ME-EPCOSI), was demonstrated by localizing specific key features in calf muscles and bone marrow of 11 healthy volunteers and five subjects with type 2 diabetes (T2D). A 3T MRI-MRS scanner equipped with a transmit-receive extremity coil was used. Localization of the ME-EPCOSI sequence was in good agreement with the earlier single-readout based EP-COSI sequence and the required scan time was reduced by a factor of two. In agreement with an earlier report using single-voxel based 2D MRS, significantly increased unsaturated pools of intramyocellular lipid (IMCL) and extramyocellular lipid (EMCL) and decreased IMCL and EMCL unsaturation indices (UIs) were observed in the soleus and tibialis anterior muscle regions of subjects with T2D compared with healthy controls. In addition, significantly decreased choline content was observed in the soleus of T2D subjects compared with healthy controls. Multi-voxel characterization of IMCL and EMCL ratios and UI in the calf muscle may be useful for the non-invasive assessment of altered lipid metabolism in the pathophysiology of T2D.

Widespread concern about energy efficiency, societal impacts and environmental quality has sparked a global interest in the reevaluation of their transportation systems. This book examines how transportation energy choices made by citizens, policy makers and planners will affect national goals of mobility, accessibility, environmental quality, quality of life, economic growth, and energy security. Chapters cover: mobility, growth and system change, including land use and transportation alternatives; energy and vehicle alternatives, including ``superefficient`` cars, alternative fuels and energy and emissions reduction policy; social cost analysis of alternative fuels; market-based demand management policies in Southern California; fuel and vehicle taxation as market incentives for higher fuel economy and the effect of taxation policies on vehicle characteristics in the US and other developed countries; and industry perspectives on technology, economics and government-industry cooperation. Based on presentations made by transportation system planners and policy-makers at the 1993 Asilomar Conference on Transportation and Energy.


The objective of this work is to establish bounded generation for two families of Sarithmetic groups. We first establish bounded generation for the special linear group over certain S-orders of a quaternion algebra. We also establish bounded generation for certain special unitary groups. This thesis consists of three chapters. The first chapter provides much of the background necessary as well as providing some applications of bounded generation. The second chapter contains the proof of bounded generation for some special linear groups, and the third chapter contains the proof of bounded generation for some special unitary groups.


The absence of a translation of the so-called "A-bomb statement", made by an American defence lawyer during the Tokyo War Crimes Trial (1946–1948), from the Japanese trial transcript has been widely cited in the Japanese discourse around the trial, both academic and popular, as resulting from a sudden attempt by the Allied Powers to cover up a reference to the world's first nuclear attack. This article shows that, contrary to the belief held universally in Japan that the courtroom's simultaneous interpreters were abruptly ordered to halt, the absence of a translation of the statement in the Japanese transcript was due to carelessness and to difficulties inherent to simultaneous interpretation. The article also demonstrates that the Japanese version of the statement produced 36 years later was a gross mistranslation, distorting the meaning of the original, and that it remains uncorrected to this day.


The external morphology and certain features of the behaviour of the adult, larva and pupa of Hypertropha, Eupselia and related Australian genera, variously assigned to the Glyphipterigidae, Choreutidae, Hypertrophidae, Copromorphidae and Oecophoridae, are described and figured. It is concluded that these genera belong to the Gelechioidea, and have close affinities with Thudaca and some other Australian genera referred to the Oecophoridae.


One popular task under several computer vision applications is camera pose estimation under video sequences. In previous work, several camera pose estimations approaches have been developed and several algorithms have been proposed. Unfortunately, most previous formulations iterative behavior and depend on nonlinear optimizations applied over some geometric constraint and this limits the performance under embedded applications. For real-time embedded applications, another approach, more efficient in terms of computational size and processing speed could be reached via hardware-based solutions, for example GPU-based solutions. In this work, we present a GPU-based solution for the camera pose problem. As early formulation we focused our algorithm for an autonomous vehicle application. Preliminary results are encouraging and show the viability of the proposed approach.


This year's private banking study by KPMG and the University of St. Gallen (HSG) shows that Swiss private banks can remain successful in the future by innovating. Besides effective implementation of new regulatory requirements, key success factors will include innovative strategies and adaptations to business models, starting with more effective segmentation techniques, an open product architecture, transparent price structures and modern distribution and communication channels.

Hardly any other industry has experienced as many changes in recent years as private banking. Times have been marked by uncertainty, volatility, dwindling margins and the increasing complexity of the core business. Now more than ever, private banks are being required to rethink their business model. The latest private banking study by KPMG and the Institute of Management at the University of St. Gallen, entitled «Success through innovation - achieving sustainability and client-centricity in Swiss Private Banking», analyzes the major, sometimes existential challenges facing Swiss private banks and ventures a glimpse forward to how the private banking industry will look in 2022.

Compensating for low profitability through innovation
Swiss private banks will be driven primarily by two trends in the period to 2022. Firstly, private banks will need to compensate for low profitability through consolidation and the related economies of scale, through international expansion and through investment in technology. Secondly, private banks will increasingly seek technology-driven partnerships in the finance industry that will open up new ways for them to position themselves in the market.

To achieve critical mass, many private banks need to grow substantially. Around two-thirds of the bank representatives surveyed believe that future survival will require an average two-fold increase in assets under management - firstly, because client requirements are becoming more complex and diverse and are necessitating heavy investment and, secondly, because growing regulatory requirements are favoring larger competitors. The study shows the areas in which private banks need to take action in order to remain competitive.

 Small, focused private banks, which historically have benefited from a very clear client focus and brand reputation, should continue to cultivate their advisory excellence. However, they need to pay increasing attention to their cost structure. Networking, partnerships and greater use of technology can help to compensate for smaller economies of scale compared with larger competitors.

 Large, diversified private banks, on the other hand, have an increasingly important cost advantage. They should continue to leverage that advantage. At the same time, however, they need to take measures to maintain and extend their client focus. Alliances and potential acquisitions should therefore be used primarily to develop a brand portfolio and address client segments in a more targeted manner.

The dual task of cutting costs while overhauling the core business will remain a major challenge for private banks. To tackle the imminent transformation necessitated by the changing environment as successfully as possible, banks need to review their strategic vision to determine whether it can withstand the disintegration of the standard industry value chain and industry consolidation.

A 50‐year‐old male patient with a history of severe valvular regurgitation underwent mitral and aortic valve replacement surgery 3 months ago. Preoperative 12‐lead electrocardiogram presented atrial flutter (AFL) and atrial fibrillation. AFL complicated with ventricular pre‐excitation was observed on current admission. The potential mechanisms underlying these changes were considered multifaceted, and valve replacement procedure may be a rare incentive factor.

OBJECTIVES
To quantify eosinophilia in sinus tissues obtained from children with chronic sinusitis and to correlate the degree of eosinophilia with history of asthma, allergy, cystic fibrosis, and preoperative computed tomographic (CT) scans.

DESIGN
Examination of surgical specimens from children who underwent functional endoscopic sinus surgery and controls.

SETTING
Tertiary care medical center.

PATIENTS
Thirty-four children who underwent functional endoscopic sinus surgery for chronic sinusitis refractory to medical treatment were divided into three groups: 13 with asthma, 11 without asthma, and 10 with cystic fibrosis. Normal sphenoid sinus mucosa was also obtained from six adults undergoing transsphenoidal hypophysectomies.

MAIN OUTCOME MEASURES
Number of lamina propria and intraepithelial eosinophils in surgical specimens, allergic status, presence or absence of asthma, and CT scans obtained preoperatively.

RESULTS
There were significantly more lamina propria and intraepithelial eosinophils in the tissue of children with chronic sinusitis compared with normal sphenoid sinus mucosa. More eosinophils were counted in the tissues of patients with asthma and cystic fibrosis compared with patients without concomitant disease, but this did not reach statistical significance. Allergy status did not affect the degree of tissue eosinophilia. Eosinophilia did not correlate with severity of mucosal disease as assessed by CT scans.

CONCLUSIONS
Tissue eosinophilia is a characteristic histologic feature of chronic sinusitis in children, especially those with asthma. The presence of allergy does not predict tissue eosinophilia. Furthermore, the degree of tissue eosinophilia does not correlate with the severity of mucosal thickening seen on CT scans.
