Coronavirus disease 2019 (COVID-19) is characterized by a high heterogeneity of clinical presentation and outcomes. This is also true for patients undergoing maintenance hemodialysis (HD), who, due to specific clinical factors and immune status, represent a distinct subgroup of COVID-19 patients. Starting from this observation in this research letter we tested and validated in two cohorts of HD patients with COVID-19 (derivation and validation cohort, respectively) an innovative model which combines linear mixed effect modeling and cluster analysis on longitudinal. This study aimed to describe a methodology allowing patient stratification from simple and widely available data. Our results could be interesting not only to improve COVID-19 management but also to support the application of longitudinal cluster analysis strategy in other clinical settings.


When developing biofidelity targets (corridors) for evaluating a dummy, response curves from multiple post-mortem human subjects (PMHS) are often averaged. Large phase differences due to large (obese) and small (thin) subjects can cause the average to be non-typical. The technique presented optimizes the phasing among all responses such that curve shapes can be optimally aligned and a typical average obtained.

In order to meet the needs of tourism and sightseeing, a large field of vision body is developed for a suspended monorail vehicle for sightseeing. The body is lightweight improved on the premise of meeting the performance requirements, and the mechanical properties of the body are analyzed and checked. After optimizing the transmission path of the body and improving the key joints and column beam sections, the weight of the body skeleton is reduced from the initial 2.7 tons to 1.5 tons, which still supports the load-bearing requirements of 143 people with full load, and the effect of weight reduction is obvious. The results show that for aluminum frame body structure, joint optimization and appropriate weakening of beam and column can disperse local stress, significantly reduce the stress level of the whole vehicle, thus effectively reducing the weight of the body framework.


Several recent randomized clinical trials comparing strategies based on control of ventricular rate versus those based on maintenance of sinus rhythm in elderly or high risk patients with atrial fibrillation have recently been reported.1,2⇓ Preliminary data from these trials suggest that the 2 strategies can produce roughly equivalent clinical outcomes. For individual patients, either approach may be appropriate because there appears to be no inherent advantage to a rhythm control strategy. These studies should cause doctors to look again at our techniques for achieving rate control in atrial fibrillation.

See p 1853

Pharmacological therapy has long been the primary technique for controlling ventricular rates in patients with atrial fibrillation. Cardiac glycosides, β-adrenergic blockers, or calcium channels blockers are used, alone or frequently in combination, to prolong atrioventricular (AV) nodal refractoriness. Increased concealed conduction in the AV node results in moderation of the ventricular rate with conduction now occurring in an irregularly, …

Conclusion: The HPLC method is used for the quality control of Fufang Kushen Changyankang Capsules.


YAG laser welding was performed on A5052-O and -H34 sheets (thickness: 2 mm) in several different welding speeds with the constant out put power of 2000 W. The authors investigated the distribution of Vickers hardness in both weld metal and heat-affected zone (HAZ), and the influence of heat treatment on Vickers hardness in the weld metal from the view point of micro segregation of magnesium in dendrites.In the HAZ of A5052-H34, the soft region where the hardness is almost the same as A5052-O base metal is developed just near the fusion boundary. Then the hardness increases with the increase in the distance from the fusion boundary toward the base metal and finally reaches the value equal to A5052-H34 base metal. This is caused by the change of the maximum temperatures in the HAZ due to welding.In the weld metal of both A5052-O and -H34 the hardness increases and dendrite arm spacing decreases as welding speed increases. When the heat treatment is performed on the weld metal at 500°C for 24 h, the hardness decreases down to the value of A5052-O base metal. According to the simulation on the diffusion of magnesium in aluminum during the heat treatment, the micro segregation in dendrites tends to decrease with the increase in both the heat temperature and the holding time. This phenomenon was confirmed by EPMA analysis. These results lead to the conclusion that the higher hardness in the weld metal than that of A5052-O base metal is caused by the micro segregation of magnesium in dendrites.


The tax legislation does not contain a clear definition of the term "tax risks". Setting up and expanding a private business is not an easy task. Apart from the idea and a great desire to do business, financial resources are necessary, the investment of which does not always bring benefits. Risks in doing business are on the watch for any entrepreneur, not only a beginner, but that who has been running his business for more than a year as well. When finances are invested in any business, the risk is always present. The causes for tax risks uprising may be: frequently changing tax legislation, in connection with which the business does not have time to master the changing rules of the game in time; failure (late) execution of fiscal liabilities in the manner and time limits provided for by the Tax Code of the Russian Federation; work with unscrupulous partners; transactions between related parties (violation of pricing rules for these transactions); minimizing taxes by applying optimization methods not provided for by the Tax Code of the Russian Federation. Tax risks exist not only for taxpayers, but for the state as well, which is associated with a possible decrease in tax revenues, which are the financial component of the budget. The article provides a classification of risks, factors that cause tax risks in an organization. The level of risk remains high when working with counterparties, and therefore, despite the adoption of Article 54.1 of the Tax Code of the Russian Federation, which replaced the concept of obtaining unjustified tax benefits, the importance of caution and prudence in choosing a counterparty does not become weaker. The author presents the key performance indicators of the control work carried out by the tax authorities for 2016–2019.

According to traditional protection concepts a distributed energy resource should be tripped as fast as possible from the grid in case of a significant low voltage condition. This is no longer acceptable because of the continuous rising share of distributed energy resources within the energy market. Uncontrolled disconnecting significant parts of the power generation during disturbances within the grid endangers the system stability of the electrical power system.


This study addresses the development undergone by para colmo , a form which is in the process of becoming fixed as an argumentative operator and additive connector. Para colmo has undergone a process of subjectification (Traugott 1995a), which is crucial in the development of discourse markers, where the presence of the speaker is manifested in various ways to cover important areas of meaning in the interpretation of the discourse. It has polarized its meaning in the negative and has progressed to indicate scalar saturation, or a position at the highest level of the argumentative scale, with an evaluation of excess on the part of the speaker. The study has been carried out on the basis of both diachronic and synchronic corpora compiled by the Real Academia Espanola, and covers the period from 1200 to 2004.


JPEG quantization tables for chroma and luminance were obtained from statistics and experiments of color images under natural light and do not have color correction function.So a novel JPEG compression framework with color constancy was proposed.The method combines the Retinex theory with the JPEG compression process,estimating illumination through iterating local space average matrix obtained form a DC coefficient matrix.Last,according to illumination influence information and block edge direction information,the luminance quantization was modulated synthetically to correct color and compress images.Experimental results show that the new quantization table is better than the existing JPEG quantization table in brightness and color fidelity with the same compression rate.


The general aims of physiological psychology research are set out. It is argued that theoretical accounts of behavioural mechanisms that ignore physiological findings may be in danger of being irrelevant. There are inherent methodological difficulties in conducting brain and behaviour research, but these are not insuperable and are sometimes misinterpreted. Progress is made generally when a number of different technical approaches can converge on the same question. Aside from the advantages of pursuing brain and behaviour work for the understanding of basic mechanisms, some possible practical benefits are discussed, especially in the context of scientific financial policy. Two broad classes of possible therapeutic procedures for treatment of brain damage are discussed.


Glioblastoma (GBM) is a highly aggressive primary brain tumor with presence of stemness-featured cells that are prone to survive from cancer treatment. We reported Sp1-induced SOD2 was associated with the process to acquire temozolomide (TMZ) resistance that the significance remained to be elucidated. Resistant models were established through long-term coincubation with TMZ in GBM cell lines, which expressed significantly higher stemness properties in extreme limiting dilution analysis (ELDA) and serial transplantation. These cells also showed increased expression of SOD2. Enrichment of stemness-featured cells by spheroid culturing or by CD133-positive cells selection resulted in increased SOD2, suggesting their associations. The impact of the protein to glioma stem cells (GSCs) was then studied through SOD2 RNA interference (RNAi), displaying downregulated stemness features in the knockdown models. Functional studies of the resistant cells showed superior scavenging ability in TMZ- or H2O2-induced ROS that would be dysfunctioned in pretreatment with SOD2 RNAi. In addition, co-treatment with the reagents over the knockdown cells resulted in enhancement of apoptosis as well as inhibition in tumor spheroid culture and cell clonogenic formation, suggesting re-sensitization to the drug. By establishing in vivo model from patient derived xenograft implantation that was obtained from clinical resistant disease, the mouse receiving combination treatment with TMZ and SOD inhibitor had lower tumor proliferation comparing to those receiving TMZ alone. These data indicate that there was an association between SOD2 and the stemness features, suggesting the protein to play important roles in regulation of GSCs behavior. Down-regulation of SOD2 levels may thus be a potential therapeutic strategy for modulating stemness properties of GSCs, making these cells more susceptive to the chemo-therapeutic agent.

This paper describes the development of a computer simulation model of an integrated supermarket refrigeration and heating system using natural refrigerants (namely ammonia and hydrocarbons). Initial resultS of the model's performance are presented, showing the influence of some of the operating parameters on system thermal efficiency. This will be validated using data collected from monitoring of a similar plant. The model and monitoring of a novel refrigeration plant are part of the UK's contribution to IEA Annex 22 work program Compression Systems with Natural Working Fluids (NWFs). INTRODUCTION The growing accept..mce of TEWI (tot..'ll equivalent warming impact) as a me..'lsure of a systems contribution to global warming. puts greater emphasis on the energy efficiency associated with the system, rather than ',the direct contribution from the refrigerant. Natural refrigerants, such a ammonia, hydrocarbons and carbon dioxide. are widely seen as offering environmental benefit<; for retail refrigeration. The inherently high efficiency, and negligible direct global warming effect of natural refrigerants, in comparison to the widely used HFCs. will have a positive impact on the TEWI rating of a refrigeration system. Also. many see tighter controls on refrigerant emissions and potential restrictions in supply of HFCs as an impetus to move towards natural refrigerants. However, many have problems assocbted with their use ammonia for example is toxic, whilst hydrocarbons are highly flammable. Conventional supermarket refrigeration systems use direct cooling, with refrigerant circulated around the building to individual display case air coolers. The refrigerant leakage rate for this type of system is significantly greater than indirect systems, adversely effecting the TEWI rating for refrigerants with a global warming effect In comparison to direct systems, the charge of primary refrigerant for an indirect system can be reduced by as much as 80-90%. Furthermore, the risk of leakage is greatly reduced for an indirect system, since the primary refrigerant is contained in a factory assembled and leak tested unit. Ammonia and hydrocarbons are only likely to be acceptable a<; refrigerants for indirect systems, where a limited charge can be contained safely. Recent changes to the British standards has widened the scope for 'natural' refrigerant usage; these are favoured more positively in Europe than in the USA. The safe and effective use of ammonia, coupled with a secondary system, represents a very sound solution with the potential for excellent energy efficiency in supermarkets. Until recently ammonia has not been used widely in supermarket refrigeration plant. However, recent developments, and considerable investment, have seen a number of full scale field trials by the majority of the main retailers, and the demand is steadily increasing in the UK. SUPERMARKET REFRIGERATION MODEL A common approach to HV AC systems has been adapted to meet the chilling, freezing, store heating and cooling demand of a typical supermarket. A single phase secondary fluid is pumped around the shop floor ring mains acting as a heat sink and heat source for freezer, chiller and heat pump compressor packs. See figure L Any surplus heat from the secondary fluid is rejected to the

An integrated approach to the creation and development of innovative startup projects in the field of information technology is considered. To conduct research, the authors proposed a model of information cycles of startup projects based on the creation of an information model of such projects. At the same time there are dynamic processes of changes in the parameters of the model, which are turbulent in nature and require the use of tools and methods of artificial intelligence for research. The key areas of knowledge of such influence are defined. The mathematical model of processes of management of development of IT startups on the basis of creation and development of a difficult IT product, taking into account influences of environments of the project is constructed, the basic characteristics are allocated and parameters are defined. To do this, the construction of predictive models is proposed to be carried out by modified Demarc trends, the method of self-organization and the neural network. The modeling of the main objective functions of the mathematical model of these processes is performed. The analysis of the received results is carried out and the conclusions are made.


Grobogan Regency is one of the areas where Tayub art is still present. One of the distinctive and unique pesindhèn who produces gendhing recordings is Lasmi. This research focuses on artist Lasmi's creativity in working on her sindhènan (song), typically distinguished by parikan, wiledan, and céngkok. This study uses a qualitative approach by collecting data through observation and in-depth interviews and analyzing data with interactive analysis. The results of this study indicate that working on parikan, which has a comical character, is a rather distinct characteristic of Lasmi's style of working on sindhènan. Lasmi's vocal style in presenting unique céngkok-céngkok can be seen in the gendhing-gendhing Tayub. Sindhènan Lasmi differs from other sindhènan lèdhèk Tayub because it is more luwes (flexible) and prênès.


This is a brief review of selected spine literature evaluating the osteogenic potential of bone marrow derived cells in vivo. There is support for a slight increase in fusion rates attributable to the addition of autologous bone marrow aspirate in graft insufficiency experiments performed in animals. There is less support for the addition of bone marrow aspirate as an isolated osteogenic source of cells or inductive agent in merely conductive matrices or carriers. To date, a definitive clinical study demonstrating the efficacy of autologous bone marrow aspirate as a graft enhancer does not exist.


MOTIVATION THROUGH CELLULAR PHONE SHORT MESSAGES IN SMOKING BEHAVIOR: A STUDY AT MUHAMMADIYAH UNIVERSITY OF PONTIANAK Abduh Ridha 1 , Ira Paramastri 2 , Trisno Agung Wibowo 3 ABSTRACT Background: An emerging health problem in Indonesia nowadays is younger age of smokers both nationally and in some certain areas. They are student, but most of them have been addicted to cigarette smokers. Considering the characteristics of teenagers, counseling method based on transtheoritical commonly used recently is short messaging technology. Objective: To identify effect of smoking cessation motivation message through short messages to self-efficacy; decisional balance; intention to quit smoking; and quantity of cigarettes smoked. Method: The study was an experiment with pretest-posttest control group design. Population of the study were smoking students at Muhammadiyah University of Pontianak that were in the pre-contemplation phase. The study involved two groups, experiment and control each consisting of 100 students. Results: Students that got short message intervention of smoking cessation encouragement did not get significant score of efficacy (α>0.05). Score of decisional balance changed significantly in the experiment group. The score decreased as much as 0.85 after intervention of encouragement through delivered short message. The score decreased due to the decrease of score in pro as much as 0.58 and the increase of score in contra as much as 0.23 (α<0.05). Changes of score in decisional balance also influenced increase of intention (R 2 =63.9%; X 2 =0.00). After the intervention there was increasing of intention in the experiment group as much as 37.5% (α<0.05). Conclusion: Students that got encouragement through cellular phone short message had better balance of decision and intention than those that did not get encouragement.

We investigated expression regulation of the human atrial myosin light chain 1 (hALC-1) gene using a cardiomyocyte H9c2 cell line stably transfected with a construct consisting of the human ALC-1 promoter cloned in front of the luciferase gene (H9c2T1). H9c2T1 cells were stimulated with vasopressin, which is known to induce cardiomyocyte hypertrophy and to activate a panel of signaling pathways. Those pathways involved in hALC-1 promoter activity regulation were dissected by using pharmacological inhibitor sub-stances. Stimulation with vasopressin was associated with nuclear NFAT translocation and significantly increased human ALC-1 promoter activity. Inhibition of calcineurin by cyclosporin A blocked the effects of vasopressin on ALC-1 promoter activity to (cid:1) 50%. This suggests that the Ca 2 (cid:1) -calmodulin-calcineurin-NFAT pathway is involved in human ALC-1 promoter activation. However, inhibition of multifunctional Ca 2 (cid:1) -cal-modulin-dependent protein kinases (CaMK) by KN-93 decreased human ALC-1 promoter activity to almost basal levels. CaMK regulation of ALC-1 promoter activity effect could well be mediated by CaMKIV, which accumulated in the 9 to 12 measurements/treatment). Significance analysis was performed using the unpaired Stu- dent's t test or ANOVA with Bonferroni as post test. Promoter sequence analysis to detect consensus binding sites was per- formed using Genomatix Matinspector.


Several polymers emit light when heated in the presence of oxygen. Experimental observations are made concerning the light from polypropylene. The portion of light detectable with a RCA-5819 photomultiplier tube is blue-violet in color. When polypropylene is at 180°C. the wavelengths of the light are between 3000 and 5150 A. The intensity of the light is determined by the temperature of the polymer, the concentration of oxygen in contact with the polymer surface, and the concentration and type of antioxidants present. For every photon of light emitted by polypropylene about 104 carbonyl groups are formed. The behavior of antioxidants in polypropylene, including concentration and synergistic effects, are illustrated by measurement of this light.


The goal of the paper is to analyze the importance of government debt in the propagation of fiscal shocks in the Argentine economy. For that reason we augment a standard fiscal policy vector Autoregression with the nominal debt to GDP ratio taken from a recently compiled IMF database. The main finding is that government debt has a crucial role for the implications of the model, and that the omission of the feedback of the debt (as a ratio of GDP) to the other variables in the system leads to very different conclusions for the effect of deficit finance government spending on the economy. Finally, we argue that not adding a measure of debt into the model is equivalent to assuming that debt as percentage of GDP is not changing following a deficit financed fiscal shock, which is in direct contraction to the implications of the optimal fiscal policy models.


To better estimate prognosis for patients with myelodysplastic syndromes (MDS) associated with clonal interstitial deletions of the long arm of chromosome 5 (del(5q)), we reviewed the medical records of 130 adults with del(5q) MDS seen at our institution over a 15‐year period. Overall median survival of this cohort was 9.5 months, shorter than reported in earlier series. The least favorable outcomes are associated with complex cytogenetics, lack of any normal metaphases, normocytic rather than macrocytic erythrocyte indices, and low baseline lymphocyte counts. Lymphopenia but not neutropenia at the time of diagnosis appears to be a new adverse prognostic indicator. Cytogenetic breakpoints defined by G‐banded karyotyping correlate poorly with particular disease features. Surprisingly, survival of patients with treatment‐related MDS was equivalent to that of de novo MDS with del(5q) in this series. Morphologic features associated with del(5q) are diverse. Most patients with del(5q) MDS do not meet criteria for WHO‐defined 5q‐syndrome, and the presence of del(5q) does not appear to modify the clinical phenotype otherwise risk‐stratified by the International Prognostic Scoring System (IPSS). Additional important prognostic factors not taken into account by the IPSS include the baseline erythrocyte indices, lymphocyte count, and clonal burden. Am. J.

Saliva is one of the most important etiological host factors in relation to dental caries. It affects the carious process by its organic and inorganic constituents; in addition to its physiological functions as (flow rate, pH and buffer capacity). The aims of this study were to determine the concentrations of major elements (calcium and phosphorus) and trace elements (ferrous iron, nickel, chromium and aluminum) in saliva among a group of adolescent girls, and to explore the relation of these elements, flow rate and pH with dental caries. Material & Methods: The study group consisted of 25 girls with an age of 13-15 years old. Dental caries was diagnosed by both clinical and radiographical examinations following the criteria of D 1-4MFS index. Stimulated saliva was collected from patients between 9-11 Am under standarized conditions, and chemically analyzed to determine the concentration of calcium, nickel, chromium and aluminum by Atomic Absorption Spectrophotometer, while salivary phosphorus and ferrous iron were determined by using colorimetric method. The average salivary flow rate was measured from total volume, and salivary pH was determined using digital pH meter. All data were analyzed using SPSS version 19. Results: All elements measured in saliva in addition to P/Ca ratio recorded statistically non significant correlation with DMFS, except ferrous Fe ions which showed statistically significant correlation (r= 0.34, P=0.05). Salivary flow rate and pH correlated weakly and statistically not significant with DMFS There were weak and statistically not significant correlations between all elements measured in saliva and salivary flow rate and pH. Conclusions: It had been found that Fe, Ni, Al and Cr ions present in very small amounts in saliva in comparison to Ca and P ions. The presence of these elements in saliva may indicate their presence in food, water and air.

A preliminary 2D transient analysis for a predicted trajectory in a representative scramjet flight path is presented. This model incorporates hypersonic convection and radiation heat transfer at the combustor walls and heat transfer to the fuel which is used as an endothermic heat sink. A heavy hydrocarbon fuel is selected due to the high density and energy release required for combustion, whilst still providing the necessary heat sink for cooling. In this process the fuel can be cracked to smaller carbon chained molecules for improved ignition and combustion. This analysis will be used in parallel with materials development to ensure appropriate composites are available in Australia for flight structures. The results show that for a postulated Mach 8 scramjet flight at 27km altitude that a combustor structure comprising of 1mm RCC, 1mm graphite foam insulation and a 3mm inconel fuel manifold the maximum temperatures reached are of the order of 1950K in the RCC. This falls within the temperature range allowed for the chosen materials to ensure that structural integrity is maintained. These results justify the further investigation into the use of composite materials and regenerative cooling with the aim of potentially using the analysis for the design of flight vehicles, including the upcoming HiFire series of experiments.


In this day and age, for Indonesian citizens who practice rihlah science in the Middle East, there is an assumption among some people that someone who does this rihlah will have a negative impact on Indonesia. In fact, since Islam entered the archipelago, the relationship between the archipelago and the Middle East has been established. Actually, how is the discourse of Islamic religious intellectuals in Indonesia and the Middle East?. This study uses the historical method. This research informs that first, the contact between Indonesian Islamic intellectuals and the Middle East has been going on since Islam entered the archipelago. Second, Islamic intellectuality in Indonesia is increasingly developing when the Muslims of the archipelago travel to the Middle East through the haj pilgrimage, study and settle in the Middle East, then develop it in the archipelago. Third, Islamic religious intellectuals in Indonesia who emerged after the Islamization process were Sufi schools. Fourth, then this Islamic intellectuality continues to develop which leads to fiqh such as the syafi'i school of thought, as well as the flow of faith such as ahlus sunnah wa al jamaah. Fifth, Islamic intellectuals in Indonesia entered the modern era with figures such as young people in Minangkabau such as Haji Muhammad Djamil Djambek, Haji Abdullah Ahmad, Haji Abdul Karim Amrullah and Haji Muhammad Thaib Umar, who have long been exploring knowledge in the Middle East.

This paper concerns the extension to the survey results detailed on 'A Secured Approach for Secret Key Extraction from Wireless Signal Strength Preserving Authentication & Security [1]'. This paper defines how authentication is implemented for secure verification scheme using the KEA algorithm and RC4 encryption is done which results in reducing the time complexity involved. Currently, the most common method for establishing a secret key is by using public key cryptography. However, public key cryptography consumes significant amount of computing resources and power which might not be available in certain scenarios. Hence this paper discovers the scheme which implements the key idea, when source sends a data to the destination, data is being forwarded to the intermediate nodes one by one, based on Received Signal Strength (RSS) secret key will be generated which is passed to both the source and the destination. A random key will be parsed by both source and destination which is exchanged between both for verification. Both of them generates hash key value of the secret keys, which will also be verified by both of them only then the data can be viewed by the destination. Thus a strong verification scheme at the destination end can be achieved. This ensures authentication of the source and destination. Authentication is a primitive that enables a node to ensure the identity of peer node with which it is communicating with. Hence the security level gets increased along with strong verification scheme is implemented by using the Secret Key Extraction mechanism. Keywords— Authentication, Handler node, Node Frame Initiation, RSS, RC4 Encryption, Security.


A new synthesis of 2-amiuo-3-methoxypyrazine, an intermediate in the synthesis of sulfalene, via 2-carbamido-3-hydroxy pyrazine and subsequent Hofmann rearrangement of 2-carhamido-3-methoxypyrazine, is described.


This paper investigates how human capital affects economic growth. Previous empirical works on this issue can be categorized by their theoretical grounds. Each of them provides different point of view on the role of human capital in economic growth, so the empirical works have been interpreted as a kind of empirical evidence of the growth models. This paper provides some empirical evidence on the issue by introducing a measure of effective human capital which quantifies the amounts of human capital effectively used for economic growth. According to the empirical results based on the effective human capital, human capital seems to lead economic growth as the way that the endogenous growth model explains.


The vertical propagation of a train of transverse harmonic hydromagnetic waves of finite amplitude in the presence of a uniform vertical magnetic field is discussed. It is shown that, although in this case the motion of the gas cannot be wholly horizontal, the vertical motion is negligible so long as the particle velocity is small compared with the local sonic velocity. Approximate solutions of the field cquations are derived, and the results are discussed in relation to the propagation of waves in the solar atmosphere. (auth)


This paper introduces Nonlinear Software Engineering Documentation Paradigm based on complexity science, which brings revolutionary changes to software documentation by making software documents automatable, graphical, colorful, traceable, virtual, maintainable, always consistent with the source code, and dynamic ("alive") – the generated documents are three in one: when a graphical document is shown, the document generator is always working and waiting for users' commands from the interface (using the document itself) for better software understanding, testing, and maintenance.


This study examines the impact of board composition on the level of voluntary disclosure in the annual reports of listed Jordanian firms. Content analysis is used to collect the required data form the 2012-annual reports of 103 firms listed on the Amman Stock Exchange. Overall, the empirical evidence provided by the study is in line with the agency theory predictions. Furthermore, they have practical implications for firms and regulators in Jordan on the importance of the board of directors and voluntary disclosure as control mechanisms for mitigating the effect of the information asymmetries and agency problems. The study shows a moderate level of voluntary disclosure in the annual reports of Jordanian firms. However, insurance firms tend to disclose more voluntary information than industrial and services firms. Also, the results suggest that Jordanian firms with a high-level of board ownership concentration tend to keep the level of voluntary disclosure low. On the other hand, the presence of foreign directors on the board seems to influence, positively, the level of voluntary disclosure in Jordanian firms. Likewise, the proportion of the old directors on the boards in Jordanian firms is very high and is significantly associated with a higher level of voluntary disclosure.


Flexible DC grid is regarded as a promoter for the future power system. In other words, it provides a feasible approach to realizing large-scale access of renewable energy sources in energy integration, interconnection and storage technology. However, fault current limiting technology is an urgent barrier for the advancement of flexible DC grid. This paper classified faults in flexible DC grid mainly into two categories, and summarized various available fault current limiting technologies. What±s more, a comprehensive outlook for advanced flexible DC grid is set to promote developments in this field. Finally, some challenges and recommendations were also summarized.


1. We investigated the mechanism of tetradecapeptide‐induced vasoconstriction by studying the metabolism of tetradecapeptide (TDP), angiotensinogen, and angiotensin I (AI) and angiotensin II (AII) by isolated perfused rat hindlimbs.


An incomplete circle of Willis (CoW) has been associated with a higher risk of stroke and might affect collateral flow in large vessel occlusion (LVO) stroke. We aimed to investigate the distribution of CoW variants in a LVO stroke and transient ischemic attack (TIA) cohort and analyze their impact on 3‐month functional outcome.


This paper argues that in depicting the worship of God by all creatures the book of Revelation recognizes the value of the whole creation for God. In Revelation's vision of heaven, the twenty-four elders are heavenly rulers, while the four living creatures are heavenly priests whose existence is wholly taken up in worship. Closer than any to the throne of God, they worship representatively, on behalf of the whole animate creation, human and non-human, as their forms indicate.


In the paper,the author proposed that multi-media can help realize the communicative teaching in English grammar teaching and the student-centred teaching principle of communicative language teaching,and meet the large information input requirement of classroom teaching of communicative teaching on the basis of introducing the communicative teaching theory.The author has also analyzed the importance and necessity of applying multi-media in college English grammar course.


The ultrastructure of the epidermis at different stages of the shedding cycle has been studied in Anolis carolinensis. Cells of the germinal layer are morphologically similar at all stages in the cycle. Immediately after leaving the germinal layer all daughter cells resemble one another closely. However, they later acquire specific ultrastructural features that enable them to be classified into six distinct fully differentiated types corresponding to the grouping previously set forth by light microscopy. A comparison of cytoplasmic filament size with the known X‐ray diffraction data suggests that the Oberhautchen and β‐layer contain a protein similar to that of avian feather; the protein in the α‐layer and lacunar tissue is similar to that in mammalian hair, and the mesos layer cells probably contain a mixture of feather and hair‐like proteins. The nature of the amorphous cytoplasmic material in the mature clear layer is as yet unknown.


This work presents an off-line model, which can provide accurate photovoltaic forecasts for utility grid managers. For this purpose we assess the performance of two models, using well known supervised machine learning techniques, for intra-hour (15 min) solar power forecasting. The first model is created using Least Square Support Vector Regression (LS-SVR) and the second using Feed-forward Neural Network (FFNN) trained with Levenberg-Marquardt algorithm (LM). The two models are compared using five performance indicators, MAE, MSE, RMSE, R2 and RRMSE (%). The best model shows a good results with an RRMSE of 15.23% and a coefficient of determination R2 = 0.96.


The concentrations of tocopherols in spinach samples (raw, frozen and canned) have been determined by HPLC using an isocratic procedure with UV detection. β-, γ- and σ-tocopherols and α-tocopheryl acetate were not detected in significant amounts. Tocopherol levels were observed to be maintained after the freezing process but very significant losses were found to occur during the canning process.

This article deals with the determination of the law applicable to the issue of arbitrability. A first distinction has to be made between subjective arbitrability - by reason of the quality of one of the parties, when this party is a State, a public collectivity or entity or public body; and objective arbitrability, by reason of the subject matter of the dispute which has been removed from the domain of arbitrable matters by the applicable national law. With respect to subjective arbitrability, it is generally accepted that a State, a state enterprise or a state entity may not invoke its incapacity to enter into an arbitration agreement to refuse to participate in an arbitration to which it has previously consented. On the other hand, the determination of the law applicable to objective arbitrability is more delicate since the solution to the issue may vary depending on whether it is decided by an arbitral tribunal, by a state court to which one of the parties has concurrently submitted the dispute or in the course of a setting-aside or enforcement procedure. If it is accepted that the lex fori generally applies to the issue when it has to be decided by a court in the context of a setting-aside or enforcement procedure or when the court is concurrently seized by a party which deems the dispute is non-arbitrable, the answer is not as clear when the question of arbitrability has to be decided by an arbitral tribunal: the law governing the arbitration agreement seems to be the prevailing answer but the law of the seat is also sometimes applied.

Two video shootings of lahars in motion were carried out in January 2002 in a river of the Semeru volcano, Indonesia. Through digital video frame analysis, we measured the flow depth, front and fluid surface velocity, and the time changes in the content, size distribution, and transport processes of large boulder particles. Complementary to the in-situ measurements during the flows, we carried out laboratory analysis of samples from a 4-m thick deposit emplaced by the largest debris flow close to the video shooting point. This combined approach allowed us to calculate the sediment deposition rate during the peak flow.


To improve the location reliability and accuracy,moving vehicle location system based on traffic wireless sensor network was studied.Based on the law that vehicle location changed along with its speed,a variable interval quantum particle swarm optimization algorithm was proposed,by which the measured vehicle location parameters could be used for the rough estimation of vehicle coordinates.For the noise interferences and signal delay,the rough estimated values of vehicle coordinates were always prone to error.The current statistical model was introduced into the algorithm under the motion constraints of vehicle,and the extended Kalman filter was used to eliminate the location errors.The proposed method was tested by the evaluation indexes of speed and accuracy.Tested result indicates that the location reliability is improved for that the enormous sum nodes of wireless sensor network can be disposed.The variable interval introduced into the quantum particle swarm optimization increases the convergence speed by 39.13%.The Kalman filter corrects the errors,and improves location precision by 56.48%.The proposed algorithm demonstrates the superiority in terms of location reliability and accuracy.


Supplemental Digital Content is Available in the Text. Introduction. In March 2020, after the COVID-19 pandemic surged in New York City, higher education had to either halt or immediately convert to fully online education. Physical therapy program directors in New York (NY) State and New Jersey (NJ) immediately recognized a need to understand the new challenges facing students. Purpose. The purpose of this paper was to identify the challenges that students in physical therapist (PT)/physical therapist assistant (PTA) programs in NY and NJ were experiencing and how institutions could respond to those challenges. Subjects. Students enrolled in a PT or PTA program in NY or NJ; N = 934 (861 PT and 73 PTA). Methods. An online survey was distributed to PT/PTA programs in NY/NJ. The survey consisted of open-ended and closed-ended questions related to academic, financial, and nonacademic issues, transition to online learning, and how institutions could respond to student challenges. Descriptive statistics and thematic analysis were used. Results. The most important challenges that students identified were quality/quantity of hands-on experiences, lack of contact with classmates, personal physical and mental health/wellness, and affording tuition and fees. Some differences were found across geographical regions and graduating cohorts. Physical therapist and PTA student cohorts had the same top concerns. Five major themes emerged from open-ended questions: communication; safe return to campus for psychomotor skills; additional academic resources; recognition of students' financial, mental, and physical health concerns; and, financial support. Discussion and Conclusion. Students in physical therapy education in NY and NJ faced similar challenges because of COVID-19 as observed by other universities worldwide. Physical therapy education can be stressful, and these additional challenges made this time extremely difficult. The findings of this survey can be used to develop a crisis management plan for university emergencies that require program modifications.

A 15-year-old boy presents to the emergency department (ED) for evaluation of chest pain. He has a history of hypertrophic cardiomyopathy, and had a transvenous implantable cardioverterdefibrillator placed 2 years ago. The chest pain started 3 hours prior to arrival to the ED. The pain is described as sharp and along the left sternal border. When he coughs or pushes on the area, the pain is worse. There is no associated shortness of breath, palpitations, or dizziness. There has been no trauma to the area. He denies headache, nausea, fever, or rash. There has been no erythema, swelling, or discharge at the site of the device pocket in the left clavicular area. The past medical history is significant for hypertrophic cardiomyopathy diagnosed at 6 years of age. The device was implanted following a syncopal event. Other risks factors included a family history of sudden death and a septal wall thickness 93 cm. His only medication is metoprolol, and he reports compliance with the prescribed dose. He has no known drug allergies. The family history is significant for sudden death due to hypertrophic cardiomyopathy in a maternal uncle at 26 years of age. The patient's mother has hypertrophic cardiomyopathy and is treated with a beta blocker. The patient has one healthy sister who has had a normal echocardiogram. He is a high school sophomore and denies illicit drug use. In the ED, the patient is acyanotic and in no distress. The heart rate is 46 bpm and the respiratory rate is 20 per minute. The blood pressure is 102/64. The head and neck exam is normal. The oropharynx and tympanic membranes are clear. The neck veins are nondistended. The chest is clear to auscultation. A left infraclavicular incision is well-healed and the device is easily palpable in that area without erythema, edema, or tenderness. However, there is reproducible tenderness to palpation over the mid left sternal border. The cardiac exam has a normally active precordium with a slow, regular rhythm. There is a normal first heart sound and a soft, physiologically split second heart sound. There is no gallop. There is a II/VI mid-frequency systolic ejection murmur heard best at the left upper sternal border. The pulses are full and equal. The abdomen is soft without tenderness. There is no hepatomegaly. The extremities are warm and well-perfused. The skin has no rash. The neurologic exam is nonfocal. An electrocardiogram was performed (Fig. 1).


Polysaccharide was extracted and isolated from Bulbus lilii by water extracting-alcohol precipitating method and purified by Sevage method and gel permeation chromatography.The components of the polysaccharide were identified and quantified by HPLC of the PMP derivatives.The results showed that the main monosaccharides contained in B.lilii polysaccharide were rhamnose,arabinose,glucose,xylose and galactose,with content of 4.82%,12.79%,47.02%,13.01% and 22.36%,respectively.


Buildings are exposed to a wide variety of external noise situations. The time course of the sound pressure level and the frequency response of external noise can vary greatly between the vicinity of roads compared to the vicinity of airports or railways. The sound insulation of facades protect the indoor spaces and the residents against external noise day and night. The German standard DIN 4109 "Sound insulation in building construction" contains the minimum requirements for sound insulation for all new buildings in Germany. All requirements are based on a singlenumber-value, the equivalent sound pressure level, without adequate respecting to the particularities of the frequency response and time structure of a sound source. The presentation shows the German standard values in building acoustics and the subject of external noise. The results of measurements of different sound sources will be shown. A new approach and an outlook for further possibilities to protect inhabitants appropriately to the noise situation will be discussed.

Summary A sample of 43 girls aged 10‐15 years were interviewed about their own and other girls' school subject choices, likes and dislikes, and which subjects girls were viewed as supposed, or not supposed, to do. The reasons for their answers were also explored. The interview material was analysed in relation to the following issues. First, whether they fitted previous accounts of the gender stereotyping of specific school subjects. Secondly, the gender‐intensification hypothesis, which predicts that masculine activities will decrease in early adolescence. Thirdly, Lillian's (1976) hypothesis of more flexible explanation for gender roles at older ages. The results showed a lack of stereotyping in girls' own preferences, a moderate level in other girls' likes and dislikes, and much more in what girls were supposed to do, or not supposed to do. There was no evidence that girls cease to like masculine subjects at menarche, but a decrease was indicated in 14‐15 year‐olds. Lillian's hypothesis that younger ag...


The paper introduces soft !-closed sets in soft topological spaces and establishes the relation between other existing generalised closed sets in soft topological spaces. It derives the basic properties of soft !-closed sets. As an application it proves that a soft !-closed set in a soft compact space is soft compact.


The anterior side of the knee is exposed during surgeries such as total knee replacement, knee ligament surgery, and reconstruction for femur epicondyle fracture. Although various complications (arterial occlusion, arterial transection, aneurysm formation, recurrent hemarthrosis, and arteriovenous fistulas) involving the knee joint following surgical intervention are reported to range from 4 to 50% of cases, many anatomical textbooks and atlases give different descriptions and lack detail (Kayler and Lyttle, 1988; Kirschner et al., 2004; Kalsi et al., 2007). It has been broadly reckoned that the femoral (FA), popliteal, and anterior tibial arteries form the arterial network surrounding the knee joint, giving rise to the descending genicular (DGA), superior medial genicular (SMGA), superior lateral genicular (SLGA), inferior medial genicular (IMGA), and inferior lateral genicular arteries (ILGA) (Standring, 2005; Lazaro et al., 2014). In most textbooks, the SMGA ramifies from the popliteal artery and divides into two branches: one anastomoses with the DGA and IMGA in the vastus medialis and the other with the SLGA on the femur (Standring, 2005; Putz and Pabst, 2006; Patrick and Thomas, 2008). To obtain a more detailed description, we performed a preliminary dissection of six embalmed Korean cadavers (four males and two females; mean age 71.3 years). The skin on the inferior area of the anterior thigh including the knee region was stripped off. The insertion parts of the vastus medialis and rectus femoris were meticulously dissected and reflected. Connective tissue between the vastus medialis and sartorius was removed to visualize the arteries. Our preliminary findings revealed that the DGA can be considered a main branch forming the network of arterial supply surrounding the knee (Fig. 1). The terminal branches of the DGA were divided into the superficial (SMGAs) and deep (SMGAd) branches of the SMGA, lying on different layers in five cadavers (10 cases). A horizontal branch of the DGA (the superior transverse genicular artery, STGA) anastomosed with or solely constituted the SLGA. A tiny branch anastomosing with the patellar artery passed through the insertion part of adductor magnus or between the insertion part and the tibia entering the popliteal fossa. In all cases there was a branch from the FA descending toward the lateral genicular region (Fig. 1). Since this branch lay on the periosteum of the tibia, we designated it the descending osseous branch (DO). The DO seemed to be a crucial blood supplier to the lateral aspect of knee owing to its thickness and clear anastomoses with the STGA and SLGA. In most cases, it branched from the FA before the ramification of the DGA. Only one case showed the DO ramifying from the FA after the ramification of the DGA. The DO Fig. 1. Overall image of the arterial distribution around the knee (left) and its illustration (right).

`̀The business of the computer is always unfinished.'' Lunenfeld (1999, page 7) loading ... `Unfinished' defines the aesthetic of new media. Internet sites, for example, the emblematic genre of new media, never solidify into a definitive form, they remain ephemeral, patchy, `̀ permanently beta'' (Neff and Stark, 2003, page 3):(1) versions change, systems evolve, applications die. This aesthetic logic of the provisional and transient is also reflected in the organisational practices of new media. In the dizzyingly fluid environment in which new media evolve, organisational practices are driven by the imperatives of bricolage, improvisation, self-organisation, and adaptability. In this theme issue we delve into these organisational dynamics of new media. We share the view that, despite the en masse depreciation of Internet stocks after April 2000, organisational practices generated in and through new media will have a lasting impact (Schultz et al, 2000; Thrift, 2000; 2001). In other words, although with the drastic end of `̀ the long summer of corporate love'' (Frank, 2000, page 356) new-media firms might have disappeared spectacularly, new-media practices have not. Studying the practices emerging from this `̀ frenzy of capitalist experiment'' (Thrift, 2001, page 430) from different (disciplinary) angles, in our view, yields insights of more general relevance for understanding organisational forms and processes in turbulent environments. The central organisational arena of these practices is the project (Braczyk et al, 1999a, page 6; Heydebrand, 1999, pages 67 ^ 69). Of course, projects as `temporary systems' with `institutionalised termination' (Goodman and Goodman, 1976; Lundin and So« derholm, 1995) are not an organisational innovation of new media. They are a long-established routine in industries organised around `one-off' activities such as construction, engineering, shipbuilding, or `old' media such as film (Faulkner and Anderson, 1987; Lundin and Midler, 1998; Winch, 1986). More recently, project organisation seems to have taken hold in a wide range of industries in which it has not previously been part of the canonical repertoire of organisational forms (Ekstedt et al, 1999; Flores and Gray, 2000). This diffusion has been accelerated by codified formulas and routines of planning, budgeting, and managing projects as distinct organisational units (PMI, 1996) which mostly have been set up unambiguously either within or between organisations (Lundin and Midler, 1998). Economic geographies of this type of `managed project' have been examined in a previous Regional Studies special issue (Grabher, 2002a). Although more conventional forms of `managed projects' have also become an essential vehicle for new-media production, `self-organised projects' reflect the genuine emergent character of this field more specifically. In evolving and self-coordinating projects, neither the division of labour between team members nor the coordination of team activities follows traditional management principles (Heydebrand and Mirön, 2002). Because design is not compartmentalised but is generalised and distributed throughout the production process, knowledge, responsibility, and accountability Guest editorial Environment and Planning A 2002, volume 34, pages 1911 ^ 1926


Initial General Comments The article is well written and the authors articulate in their presentation. The article compares several techniques that measure water vapour in the troposphere over the 4 year period form 2005 through the beginning of 2009. Although the article is an empiriclal assessment focusing on the scatter among PWV measurements a table showing the expected precision for each technique from the data provider would help the reader know the data quality at the onset. Specific Science Comments

Thinking about solving the problem of high consumption and high cost in the electricity bill, this study proposes to present proposals to increase the energy efficiency of the site. In this sense, it is proposed an energy efficiency analysis of a Public Higher Education Institution in the Municipality of Manaus, Amazonas. A building survey was performed on the appliances and components of the building's electrical system, as well as an assessment of electricity bills to measure consumption. In order to verify voltage, current and power, electric measuring instruments were used to elaborate proposals aiming at increasing the energy efficiency of the site. Through the results obtained during the building survey at the IES, it was possible to observe the anomalies of the systems and indicate proposals for repair or replacement of equipment to increase the energy efficiency of the building. From the results obtained from the invoice it was possible to propose a new value of demand contract and by comparing the collected data, we identified the appliances that make the electric system less efficient, in this case, the air conditioners. Recurring payment problems with overconsumption were encountered. Adhering to the proposal of a new contract value with possible annual savings of R $ 22,543.92 referring to the payment of the demand portion in the electricity bill. It is also proposed to replace current lamps with LED tube lamps, reducing energy consumption by 9,122 kWh / month and saving R $ 3,263.57 per month. As for the proposal presented for the HVAC system, given the exchange of existing appliances for new and energy efficient, was not viable. Despite representing a reduction of 41869.91 kWh / month, the expected investment is not paid.


This paper describes an approach for the numerical analysis of container ship slamming and whipping and various parameters that influence slamming and whipping. For validation purposes, the numerical analysis results were compared with experimental results obtained as part of the Wave-Induced Loads on Ships Joint Industry Project. Water entry problems for two-dimensional (2D) sections were first solved using a 2D generalized Wagner model (GWM) for various drop conditions and geometries. As the next step, the hydroelastic numerical analysis of a 10,000-TEU container ship subjected to slamming and whipping loads in waves was performed. The analysis method used is based on a fully coupled model consisting of a three-dimensional (3D) Rankine panel model, a 3D finite element model (FEM), and a 2D GWM, which are strongly coupled in the time domain. Parametric studies were carried out in both numerical and experimental tests with various forward speeds, wave heights, and wave periods. The trends observed and the validity of the numerical analysis results are discussed.


We study the set of boundary singularities of arbitrary classical solutions of genuinely nonlinear $2\times2$ planar hyperbolic systems of the form $D_kR_k=0$, where $D_k$ denotes differentiation in the direction $e^{i\theta_k(R_1,R_2)}$, $k=1,2$, and where the defining functions $\theta_k$ satisfy (i) $\theta_2=\theta_1+\frac{\pi}{2}$, and (ii) $A\leq|\frac{\partial\theta_k(R)}{\partial R_k}| \leq B$, for all $R\in\mathbb{R}^2$, $k=1,2$, for some positive constants $A,B$. We show that for any system of this kind there is a $\tau<1$ such that for any locally Lipschitz solution R in a smoothly bounded domain G, the set of points of $\partial G$ at which R fails to have a nontangential limit has Hausdorff dimension at most $\tau$, and, on the other hand, for any such system for which the $\theta_k\in C^\infty(\mathbb{R}^2)$, we construct a $C^\infty$ solution R on a half-plane $\mathbb{H}$ for which the set of points of $\partial\mathbb{H}$ at which R fails to have a nontangential limit has positive Hausdor...

We analyze the effect of a finite volume on the thermodynamic potentials of a relativistic quantum field theory defined on a hypertorus at vanishing chemical potential. Using the symmetries of the Euclidean partition function, we interpret the thermodynamic observables as the expectation value of the energy-momentum tensor in the same theory living on a β × L2 volume. In the case where the screening correlation lengths in the thermal system are finite, we obtain a closed formula for the leading finite volume effects in terms of the smallest screening mass. This formula can be used to estimate, and possibly correct for, the leading finite volume effects in lattice calculations of QCD thermodynamics.


In the Caldenal region, overgrazing causes important soil losses due to water erosion. The magnitude of this process is related to soil properties and vegetation cover. The objective of this study was to evaluate nutrient losses due to water erosion on an Entic Haplustoll and a Typic Ustipsamment. Treatments were: natural vegetation, clipped vegetation with residue reduction, and bare soil. Evaluations were carried out in March and September using a rainfall simulator (28 mm in 30 min) over 2 m2 runoff plots. Organic carbon (OC), total nitrogen (N) and available phosphorus (P) were determined on sediments. Average sediment OC and N content was higher in the Haplustoll (59.5 g.kg-1 and 4.3 g.kg-1) than in the Ustipsamment (37.6 g.kg-1 and 2.2 g.kg-1). P was lower in the Haplustoll (29.8 mg.kg-1) than in the Ustipsamment (40.2 mg.kg-1). Losses of N and P were significantly higher in March than in September. In the bare soil, nutrient losses were higher in the Haplustoll than in the Ustipsamment, while with vegetation cover, erosion was of lesser importance, and similar for both soil types. Organic carbon was the soil constituent that suffered the highest losses due to water erosion.


A 44-year-old man was admitted to our hospital because of melena with a hemoglobin of 4.3 g/dL. He denied use of aspirin, non steroidal anti-inflammatory drugs or any other medication and his medical history was unremarkable. However, he had been subjected to a laparoscopic adjustable gastric banding (LAGB) operation in 2007 for the treatment of morbid obesity.

During the emergency esophagogastroduodenoscopy, a foreign body eroding the stomach wall was noted. The foreign body was white-yellow in appearance and was seen eroding the lesser curvature of the cardiac area (Fig. 1A). Adjacent to it, a large ulcer was also noted, while fresh blood and a large blood clot at the gastric body were seen (Fig. 1B). The patient was operated the following day and the gastric banding placed on the patient 5 years ago was seen eroding the stomach. The gastric banding was removed and the patient had an uneventful recovery.

LAGB is currently the most common bariatric surgical procedure for the treatment of morbid obesity, because it is adjustable, minimally invasive and easily reversible, while it does not cause metabolic side effects [1]. Band erosion is a rather uncommon complication of LAGB, with an incidence of 1% [2]. A high index of suspicion is required for diagnosis, as most patients are asymptomatic. When symptomatic, complaints include loss of restriction, nonspecific epigastric pain and gastrointestinal bleeding. The diagnosis is often made at the time of gastroscopy and the recommended treatment is complete removal of the eroded gastric band.


Abstract The problem of determining when a unitary element is a product of Cayley unitary elements is completely solved for simple artinian rings of characteristic not 2. Theorem 1. Let D be a division ring of characteristic not 2. Suppose that R = D n assumes an involution which induces a non-identity involution on D . Then any unitary element in R is a product of two Cayley unitary elements. Theorem 2. Let F be a field of characteristic not 2. Suppose that R = F n assumes an involution ∗ of the first kind. Then any unitary element in R which is a product of Cayley unitary elements must have determinant 1. Conversely, any unitary element in R of determinant 1 is a product of two Cayley unitary elements, except when F = GH (3), n = 2, and ∗ is given by [formula].


Photo typesetting belongs to the rectangular packing problems, currently the algorithms of rectangular packing problems can be divided into two categories: heuristic methods and modern intelligent based methods. For both of these methods, the similarity of contents do not be well considered, the packing order of the rectangular pieces are chaos. Therefore, this drawback will cause problems for photo typesetting. In this paper we propose a hybrid algorithm for the photo typesetting problem based on kinship. According to our algorithm, the kinship of difierent photos is calculated by their absolute paths, and then all photos are packed based on the distance of their kinship. Compared with the existing methods, according to the computation of difierent scales of tests, our algorithm shows faster typesetting speed and higher utilization ratios. This algorithm could solve the sort problem caused by chaos typesetting photos of difierent customers after lots of photos were typeset. Our algorithm could greatly improve the practical application of photo typesetting.


The driver's task in traffic is to evaluate traffic situations and act in accordance with the estimate. One of the most common causes of road crashes is "incorrect estimated of the traffic situation". Correct perception of surroundings is one of the prerequisites for safe and successful driving. To investigate the mentioned issue, the authors of this paper conducted an experimental study with the aim of determining what affects the estimation of the object distance. In contrast to previous studies known from the available literature, our study presents experimental research of the estimated distance of 3D stimuli in three environments by direct observation, a rear-view mirror, and a camera display in a vehicle. One-hundred-and-sixty-four participants participated in the experiment. The research results show statistically significant differences in the estimation of the distance of 3D objects for different colors. Participants, for the largest number of stimuli, best estimate the distance from direct observation than through the rear-view mirror, while they make the most mistakes when estimating the distance of 3D objects using the camera display in a vehicle. On the other hand, in all described conditions, the respondents estimated the distance to the blue and green objects with the most significant errors.


Fiber Bragg Grating sensors (FBG) have a great resistance to embedding processes. This property is very useful for monitoring parameters at inaccessible places. Embedded fiber optic sensors into composites have been studied for a long time, but embedding a fiber sensor into metallic structure is beginning to study. Recently, this has raised interest due to embedded FBG in the metallic structure provide capabilities for controlling parameters of the structural health status and also information about their own process of deterioration. The embedding process of the FBG sensors involves the fusion of structural metallic material. During this process, very high temperatures are achieved that could damage the Bragg grating or the silica fiber. To protect the sensor during the embedding process, a fiber coating is made with a metallic material with a high melting point. In this paper we study three different techniques for coating a FBG sensor: physical vapour deposition (PVD), electroless deposition and electroplating. This paper describes the experimental procedure for coating metallic fiber optic sensors and the optical characterization.


The purpose of the present paper is to develop C Virtual Elements in three dimensions for linear elliptic fourth order problems, motivated by the difficulties that standard conforming Finite Elements encounter in this framework. We focus the presentation on the lowest order case, the generalization to higher orders being briefly provided in the Appendix. The degrees of freedom of the proposed scheme are only 4 per mesh vertex, representing function values and gradient values. Interpolation error estimates for the proposed space are provided, together with a set of numerical tests to validate the method at the practical level.


At present, the Ozawa method is widely used to evaluate the internal compatibility of explosives, which always results in large amount of experimental workload.In our lab ,a single non isothermal DSC curve method was employed to calculate kinetic parameters of thermal decomposition,by which the internal compatibility of SEFAE composite fuel can be evaluated.By comparison,we have found that the deviation between the two methods is very small. The experimental results also show that SEFAE composite fuel is of good internal compatibility.


The support for function symbols in logic programming under Answer Set Programming semantics (ASP) allows to overcome some modeling limitations of traditional ASP systems, such as the inability of handling infinite domains. On the other hand, admitting function symbols in ASP makes inference undecidable in the general case. Thus, the research is lately focusing on finding proper subclasses of ASP programs with functions for which decidability of inference is guaranteed. The two major proposals so far, finitary programs and finitely-ground programs, are complementary, to some extent; indeed, the former are conceived for allowing decidable querying (using a top-down evaluation strategy), while the latter for allowing finite model computation (using a bottom-up evaluation strategy). One of the main advantages of finitely-ground programs is that they can be directly evaluated by current ASP systems. However, many programs lie outside this class, such as, in general, positive finitary programs. Indeed, ground queries over such programs can be easily answered by means of top-down techniques; bottom-up approaches, instead, are, in general, unsuitable. In this work we present a proper adaptation of the magic-sets technique that aims at making query answering over positive finitary (normal) programs feasible by means of bottom-up techniques, i.e., those all current ASP systems rely on.


Despite certain limitations, the RI model is widely used in the interpretation and prediction of oblique propagation characteristics, for example, MUF. A special role is played by the adaptation (assimilation) of the model to the current diagnostics data, which makes it possible to correct the model in real time. The most widely used adaptation is to the main parameters of the ionosphere foF2 and hmF2. With the possibility of measuring the total electron content TEC, the values of this parameter are used for adaptation through the definition of foF2 using, for example, the equivalent slab thickness of the ionosphere or other approaches. However, in almost all cases there is a residual deviation of the calculated values of the MUF from the experimental MOFs, which is attributed to the difference in the shapes of the model and real N(h)-profiles. In this paper, to eliminate the residual deviation, the values of the B0 and B1 parameters are used, determining the shape of the N(h)- profiles of the lower ionosphere, which is close to real. One of the most quiet days was chosen on February 13, 2014 on the Dickson-Pevek path of oblique sounding. It is shown that the use of B0 and B1 can reduce the residual discrepancy, but does not remove it completely. The reason is the lack of accuracy in determining B0 and B1 in the high-latitude zone.

Detailed studies of exudate macrophage-mediated inflammatory response in fish have not been possible mainly due to incomplete purification of inflammatory macrophages. Many studies have demonstrated that neutrophils migrate to the site of inflammation before macrophages during the acute phase of inflammation1-3). As previously described in mammals4), neutrophils were found to be involved in the migration of macrophages to the inflammatory site. In this study, we elicited exudation of macrophages with injection of neutrophil lysate and isolated inflammatory macrophages at high purity in tilapia.


Calcium oscillations and waves are often behind instances of extra depolarization in cardiac cells, eventually giving rise to life-threatening arrhythmias. In this work, we study the conditions for the appearance of calcium oscillations in both a detailed subcellular model of calcium dynamics and a minimal model that takes into account just the minimal ingredients of the calcium toolkit. To avoid the effects of homeostatic changes and the interaction with the action potential we consider the somewhat artificial condition of a cell without pacing and with no calcium exchange with the extracellular medium. This permits us to isolate the main reasons responsible for the oscillations by controlling externally the total calcium content of the cell. We find that as the calcium content is increased, the system transitions between two stationary states, corresponding to one with closed ryanodine receptors (RyR) and most calcium in the cell stored in the sarcoplasmic reticulum (SR), and another, with open RyRs and a depleted SR. In between these states, calcium oscillations may appear. This transition depends very sensitively in the amount of buffering in the cell. We find, for instance, that at high values of calsequestrin (CSQ) oscillations disappear, while they are present for a broad range of parameters at low values of CSQ. Using the minimal model, we can relate the stability of the oscillating state to the nullcline structure of the system, and find that its range of existence is bounded by a homoclinic and a Hopf bifurcation. Author summary In cardiac cells, calcium plays a very important role. An increase in calcium levels is the trigger used by the cell to initiate contraction. Besides, calcium modulates several transmembrane currents, affecting the cell transmembrane potential. Thus, dysregulations in calcium handling have been associated with the appearance of arrhythmias. Often, this dysregulation results in the appearance of periodic calcium waves or global oscillations, providing a pro-arrhythmic substrate. In this paper, we study the onset of calcium oscillations in cardiac cells using both a detailed subcellular model of calcium dynamics and a minimal model that takes into account just the minimal ingredients of the calcium toolkit. Both reproduce the main experimental results and link this behavior with the presence of different steady-state solutions and bifurcations that depend on the total amount of calcium in the cell and in the level of buffering present. We expect that this work will help to clarify the conditions under which calcium oscillations appear in cardiac myocytes and, therefore, will represent a step further in the understanding of the origin of cardiac arrhythmias.


With the availability of easy access to the Internet, and the proliferation of various mobile devices, people can get access to mobile multimedia ubiquitously in order to have a desktop experience. Mobile multimedia refers to different types of multimedia content (e.g., text, images, audios, and videos), which are accessed via heterogeneous mobile devices, such as mobile phones, portable devices, and smartphones. Mobile multimedia services and applications have tremendous potential in the healthcare sector. Currently, as the healthcare sector is increasingly dependent on mobile multimedia services and applications, many challenges remain unsolved for the successful deployment of mobile multimedia services in order to have a balance between power-limited mobile devices and resource hungry medical multimedia content. This Special Section aims to theme innovative research achievements in the field of related techniques, applications, services, and systems for mobile multimedia healthcare. The articles in this Special Section bring together academic and industrial researchers to identify and discuss technical challenges and recent results related to mobile multimedia for healthcare. As an application area, mobile multimedia is one of the most active and successful fields of use in the domain of the healthcare industry. The Special Section focuses on particular aspects of mobile multimedia for healthcare, such as comprehensive data sensing, assistive sensory media, and sharing mobile-healthcare big data. After a rigorous review process, we accepted the following articles to form the Special Section. In the article titled, ''DEEP-SEE FACE: A mobile face recognition system dedicated to visually impaired people,'' by Mocanu et al., the authors introduce a novel assistive device designed to improve cognition, interaction, and communication of visually impaired (VI) people in social encounters. The proposed approach jointly exploits computer vision algorithms and deep convolutional neural networks in order to detect, track, and recognize, in real time, various people's existence in video streams. The major contribution of the article concerns a global, fixed-size face representation that takes into account various video frames while remaining independent of the length of the image sequence. For this purpose, the authors introduce an effective weight adaptation scheme that can determine the relevance assigned to each face instance, depending on the frame degree of motion/ camera blur, scale variation, and compression artifacts. The experimental results carried out on a large-scale data set validate the proposed methodology with an average accuracy and recognition rates superior to 92%.When tested in real-life indoor/outdoor scenarios, the proposed framework proves to be effective and easy to use, allowing the VI people to access visual information during social events. In the article, ''Voice disorder identification by using machine learning techniques,'' by Verde et al., the authors introduce an exhaustive comparison between the most used machine learning algorithms existing in the literature. The aim of this study is to identify the techniques capable of discriminating between pathological and healthy voices with more accuracy. This is fundamental to realizing a valid and precise mobile health system and a promising solution for people who desire the detection, monitoring, and treatment of their health conditions anywhere and at any time. All analyses are performed on a dataset of voices selected from the freely available Saarbrucken Voice Database. They show that the best accuracy in voice disease detection is achieved by the support vector machine algorithm or the decision tree one, depending on the features evaluated by using opportune feature selection methods. The article ''Performance analysis of personal cloud storage services for mobile multimedia health record management,'' by Akter et al., focuses on performance analysis of personal cloud storage services for mobile multimedia personal health record (PHR) management. In particular, the authors investigated using qualitative and quantitative analyses of the strengths and weaknesses of personal cloud storage services for PHR management scenarios. The qualitative analysis includes chunking, bundling, deduplication, delta-encoding, and data compression features. The quantitative analysis includes control data overhead, application data exchanged, and impact of data size on number of packets, as well as transmission rate, synchronization initialization time, and protocol overhead. Experimental results on various benchmark cloud storage datasets showed satisfactory outcomes. Wearable technology and personal health devices (PHDs) play a critical role in shaping the future of healthcare. The International Organization for Standardization (ISO) realized the role of personal health systems and proposed the 11 073 family of standards. To this end, the article ''ISO/IEEE 11 073 personal health device (X73-PHD) standards


To solve their design problems, engineers draw on a vast body of knowledge about how things work. Examining previously unstudied historical cases, this author shows how engineering knowledge is obtained and presents a model to help explain the growth of such knowledge.

In order to obtain better generalization performance in supervised learning, model parameters should be determined appropriately, i.e., they should be determined so that the generalization error is minimized. However, since the generalization error is inaccessible in practice, the model parameters are usually determined so that an estimator of the generalization error is minimized. The regularized subspace information criterion (RSIC) is such a generalization error estimator for model selection. RSIC includes an additional regularization parameter and it should be determined appropriately for better model selection. A meta-criterion for determining the regularization parameter has also been proposed and shown to be useful in practice. In this paper, we show that there are several drawbacks in the existing meta-criterion and give an alternative meta-criterion that can solve the problems. Through simulations, we show that the use of the new meta-criterion further improves the model selection performance.


NiO layers were coated in situ onto Ni-silicide nanowires by an oxidation in air. The surface of the nanowires had been previously roughened by etching in HF solution. It is found that the roughened surface is very helpful to enhance the in situ coating ability of NiO on the nanowires. When the resulting samples were used as anodes for lithium-ion batteries, a high reversible capacity of 1.28 mA h cm−2 was obtained for the surface-roughened nanowires with 30 min HF-treatment, which is 3 times higher than that of the nanowires without HF-treatment. The current density can reach up to 2.15 mA cm−2 for the 60 min HF-treated and then oxidized nanowires, while the capacity is maintained at as high as 0.52 mA h cm−2. The improved cyclic performance could be attributed to the roughened surface of the nanowires, which enhanced the coating ability of the NiO layers, and provided a porous structure that is of benefit to increase the area of the electrode/electrolyte interface for the adsorption of ions. In addition, the Ni-silicide nanowires can improve the electrode conductivity and act as a stable support for the NiO coating layers during cycling, making a positive contribution to the electrochemical performance.
