Over the last decade, drug-eluting stents (DES) have undergone substantial modifications with thinner struts and more biocompatible durable polymer (DP) or biodegradable polymer (BP). In DP-based DES, after drug elusion has been completed, DP remnants may trigger of local inflammatory vascular reactions and promote delayed healing, leading to accelerated neoatherosclerosis (NA). Thus, BPs have been developed to reduce the above-mentioned risks. Recently, poor strut coverage and in-stent NA are increasingly recognized the cause of late stent failure, but it is unclear whether BPs can reduce the incidence of NA and the poor stent coverage as compared to DPs.

 The purpose of this study was to compare the incidence of NA and the stent coverage using optical coherence tomography (OCT) between the DPs and the BPs.

 Between July 2016 and April 2018, 127 consecutive patients with new-generation DES who underwent 8-month follow up OCT imaging were enrolled. Patients were divided into the two groups: DP group who had the new-generation durable polymer everolimus-eluting and zotarolimus-eluting stents and BP group who had the new-generation biodegradable polymer sirolimus-eluting and everolimus-eluting stents. We compared patient characteristics including hypertension, dyslipidemia and diabetes mellitus and 8-month follow up OCT findings including NA, uncovered struts and malapposed struts between the two groups.

 The DP group comprised 64 patients (50.4%. The incidence of NA, uncovered struts and malapposed struts were similar between the two groups (DPs vs BPs, 1.56% vs 7.94%, P=0.11; 7.80% vs 5.88%, P=0.16 and 2.76% vs 2.01%, P=0.43, respectively) (table). The other parameters were also similar between the two groups.
 Table 1 DP group (n=64) BP group (n=63) P value Hypertension 44 (68.8%) 50 (79.4%) 0.2251 Dyslipidemia 39 (60.9%) 37 (58.7%) 0.8573 Diabetes mellitus 25 (39.1%) 30 (47.6%) 0.3731 8 month OCT follow up findings   Neoatherosclerosis 1 (1.6%) 5 (7.9%) 0.1147   Uncovered struts 7.8% (2.8–20.4) 5.9% (0.7–16.7) 0.1616   Malapposed struts 0.2% (0–2.8) 0% (0–2.8) 0.4392

 The new-generation DP based-DES may have similar effects on vascular response compared to the new-generation BP-based DES during 8-month follow-up period.


Structural Health Monitoring is mandatory to properly perform health assessment and preventive maintenance planning. Most of approaches available in the literature are based on discrete monitoring, which does not allow for a continuous assessment of the structure status as well as to handle fast alerting in case potential anomalous behaviors are highlighted by instrumental observations. This paper deals with the development of a low-cost multisensor node aimed to provide information on both inertial vibrations and tilt experienced by the investigated structure. Moreover, a dedicated signal processing approach is proposed with the aim of both performing the sensing node assessment and analyzing the frequency content and correlation of recorded signals. Results of different experimental surveys are reported. The estimated resolution of acceleration and tilt measurements are 0.3 mg and 0.016°, respectively.


ABSTRACT Enuresis affects up to 20% of children of 5 years old, enuretic children present arginine vasopressin secretion deficiency, compared to normal children. To keep the level of antidiuretic hormone in the body, the aim of this work was to develop natural rubber latex membranes loaded with desmopressin peptide and characterize its in vitro release. Results demonstrated that 60% of desmopressin incorporated in natural latex was released up to 96 h. Furthermore, hemolysis tests showed no detectable disturbance of the red blood cell membranes. Based on the results, it was possible to conclude that natural latex membranes are able to load desmopressin. GRAPHICAL ABSTRACT

The growth and diversification of alcohol and drug services and the increased demand for accountability of public monies, has stimulated the development of monitoring and review systems. This article describes the development and utilisation of an agency review system to monitor a broad range of alcohol and drug agencies. The review contains standard practices and indicators which identify and measure the quality of organisational structure and services. This is a developmental approach to agency review which emphasises the involvement of management and staff in a process evaluation of their agency. This system has been piloted in Victoria and its future implementation and its wider application is discussed.


Introduction: Hysteroscopy is considered the gold standard in the evaluation of the uterus and its diseases. Its use as a diagnostic technique is an outpatient procedure, usually well tolerated by patients, allowing resumption of activities right after its completion. The teaching of the hysteroscopic technique tends to be time consuming, with a slow learning curve. Therefore, defining the impact of the histeroscopy's learning curve on the intensity of the pain felt by the patients can help improving the organization of hysteroscopy services, maximizing learning and reducing patient discomfort. Objectives: To analyze, with the construction of a learning curve, the possible relationship between the number of hysteroscopic procedures performed by the doctor and the intensity of pain reported by the patient during the exam. Methods: A prospective cohort study with 403 patients who underwent hysteroscopy in the Hospital Universitario Sao Jose (HUSJ). Results: 72.45% of the patients rated the pain as mild and 5.95% , as strong. Furthermore, Correlation between the learning curve and the pain reported by the patient during outpatient hysteroscopy procedure without anesthesia


Protoplanets formed by core accretion can become massive enough to accrete gas from the disk they are born in. If the planetary proto-atmosphere exceeds a critical mass, runaway gas accretion starts and the planetary atmosphere collapses into a gas giant. In recent years, many close-in super-Earths have been observed which raises the question on how they avoided becoming hot Jupiters. We investigate the recycling hypothesis as a possible mechanism to avoid the collapse of the atmosphere. We use three-dimensional radiation-hydrodynamics to simulate the formation of proto-atmosphere in the local frame around the planet. In post-processing we use tracer particles to calculate the shape of the atmosphere and determine the non-uniform recycling timescale in a quantitative manner. Our simulations converge to a quasi-steady state where the velocity field of the gas does not change anymore. For the parameter space explored, a = 0.1 au, m_c ∈ [1, 2, 5, 10] M_Earth, we find that recycling of the atmosphere counteracts the collapse by preventing the gas from cooling efficiently.


The results of structuring, analysis and synthesis of objects and processes of the road network section in the northeastern part of Shchukino District in Moscow are presented in the article.

The features of transport and pedestrian flows of the road network section are distinguished.


This work is aimed at identifying some key characteristics (energy, geometry, and spin) concerning Rhn particles (2 = n ≤ 8) to perform further studies on adsorption and coadsorption sites of pollutants (CO and NO). The DFT methods of the Gaussian 03 program with the LANL2DZ basis set and the LANL2 potential are used. With the purpose to obtain a better nanoparticles definition, five different functionals were tested: B3LYP, O3LYP, BPW91, BP86, and HCTH; and the corresponding results are used to determine which of them best describes distances, spin, and gives acceptable highest vibration frequency and binding energy values, by comparing these results with values measured or calculated by many other authors. For the structure optimization process of the particles, the initial geometric shape was taken mainly from the literature, using the Rh–Rh distance: 2.67 A, known for the bulk; and doing a complete optimization. We also considered flat nanoparticles structures, which most of them display three-dimensional structures after the optimization process. The few flat shapes are mainly higher in energy than those of three-dimensional structure. For some Rhn particles for different n values, the spin of the ground state present degeneration. In some cases, the optimization process changes the initial geometry, but in most cases, there are only minor changes in bonds and geometry. © 2009 Wiley Periodicals, Inc. Int J Quantum Chem, 2010


This study sets out to investigate the extent of discrimination against sexually oriented minorities in the workplace and does so by contrasting the earnings of homosexuals and heterosexuals. Research studies have found little evidence of large income gaps between heterosexuals and gay men and lesbians in mainland China. However, similar studies on sexual orientation minorities demonstrate that mainland China does discriminate against these minorities in the workplace, and there is a lack of anti-discrimination legislation. This could be because these minorities prefer to conceal their sexual orientation in mainland China, for fear of suffering discrimination.


This study examined the expectations to help victims of intimate partner violence held by potential informal helpers such as friends and family. A total of 157 college students viewed one of two videotaped domestic violence scenarios, which varied on victim "provocation." The present study tested a specific model in which victim blame mediates the relationship between helper characteristics and the type of intervention helpers expect to use. The model accounted for 22% of variance in general victim blame,40% of variance in blame toward the victim's specific behavior/characteristics, and 27% of variance in the expectation to use specific helpful inter ventions. High perceived provocation and violence-condoning attitudes held by participants predicted greater victim blame, and general victim blame appeared to mediate the relationship between attitudes and intervention. Female participants demonstrated less general victim blame and provided more helpful interventions than males. Implications for educational programs and continued research are discussed


Statement of problem: Management of open apices teeth is one of the most serious problems for dentists. Contemporary endodontics proceeds to single step techniques such as apical plug and customized cone for management of these cases. Purpose: The purpose of this study was to compare apical microleakage between customized cone and apical plug techniques on open apices polyester made root canals. Materials and methods: In this in vitro experimental study, 68 clear models were made from polyester in two different forms: S models (round canals), and L models (oval canals). Thirty models (15 S and 15 L) were obturated with customized cone technique and 30 models (15 S and 15 L) were obturated with apical plug technique using Ca(OH)2 as an apical barrier. Eight models were considered as positive and negative control groups. Models were immersed in methylene blue for 48 hours and maximum linear dye penetration of each was measured by three separate observers. Student t test was used for statistical analysis of the findings. Result: The results illustrated that the mean leakage of the customized cone group was statistically greater than apical plug group (p<0.05). In addition, when comparing L and S models in customized group, L models showed more linear leakage than S models (p<0.05), but this difference was not significant in apical plug technique. Conclusion: The finding of this study indicated that the apical plug technique, when using Ca(OH)2 plug as a barrier may produce a better apical seal than the customized cone technique in short term Key words: Open apex, Obturation, Apical microleakage


The atomic structures of a number of high-angle tilt grain boundaries in NiO bicrystals have been studied by high-resolution electron microscopy (HREM). Crystallinity is always maintained right up to the grain boundary (GB). Grain boundary planes bounded by a (100)-plane are preferred; however, symmetrical facets are also found at each misorientation. A tendency to match atomic planes across the GB is not only observed in symmetrical, but also in asymmetrical, GBs. Structural units can be clearly recognized in symmetrical GBs. Contrast differences suggest that a multiplicity of structural units exists for some GB configurations. Frequently symmetric GBs also show deviations from mirror symmetry. Multislice image simulations indicate that the Fresnel-like contrast associated with HREM GB images is not particularly sensitive to GB relaxation.


The evidentiary process requires evidence which is regulated under the civil procedure law in Article 164 HIR. Supreme Court decision number 3591K/Pdt/2018, discusses documentary evidence in the form of an agreement to transfer and transfer land rights. Mahakamah Agung's decision number 3591K/Pdt/2018 states that the deed has no legal force because the land object of the dispute has been issued a legally valid right to build (HGB) certifi cate. The purpose of this paper is to fi nd out the legal considerations of the decision of the Supreme Court of the Republic of Indonesia regarding the validity related to positive law in Indonesia. The research method used is a normative juridical approach with research specifi cations in the form of descriptive analytical through secondary data obtained from literature studies. The data analysis method used is qualitative normative method. The conclusion was obtained that the deed of agreement of transfer and transfer of land rights as outlined in deed number 255 is legally valid because the agreement was made by fulfi lling the validity requirements of the agreement in Article 1320 of the Civil Code, however the judge did not provide further explanation in the judge's consideration regarding the validity of the letter.


Abstract The technique of aperture synthesis is well developed in radio astronomy. When applied to the optical regime, aperture synthesis allows one to partially overcome the blurring effects of the atmosphere and increase the angular resolution of large telescopes to the diffraction limit. MAPPIT (Masked APerture-Plane Interference Telescope) is a multi-element interferometer which operates at the coude focus of the 3.9 m Anglo-Australian Telescope. This instrument has recently been reconfigured to operate in a dispersed mode so that simultaneous observations in a band of wavelengths are possible. We will discuss this instrument's new mode and present observations of the double star δ Sco and an angular diameter of the previously unresolved red giant β Gru.


Gas is one of the most important factors which causes coal and gas outburst and can influence the mechanical characteristics of coal. Coal itself is a kind of elastic carbonaceous material which can swell and shrink under the influence of gas adsorption and desorption. Solid deformations influence the porosity of coal which also changes its adsorption and desorption capability. Gas pressure due to gas adsorption in porous materials is the cause of elastic deformation of coal, which can be assessed by direct experimental measurements. In this paper, briquette coal samples are made with different sizes of coal particles and the deformations are tested during the process of gas adsorption and desorption in samples under different gas pressures. The results show that coal swells during gas adsorption and shrinks during desorption. Deformation of different coal samples under different gas pressures is variable. It is further observed that deformation of coal is proportional to gas pressure and particle size. Also, deformation is not recoverable and residual deformation develops. The relationship between residual deformation and gas pressure is derived. This study helps to reveal the damage mechanism of pore gas in cola mass.

This study aimed to compare the risk of metachronous cancer, overall recurrence and mortality between segmental and extended colon resections in patients under the age of 50 with sporadic CRC.


During the transitional period of China,our teaching theory and training mode of cultivating economics talent fall behind the Chinese-style market economic progress,so we should learn from the western,especially the American ways of teaching and cultivating economics talent.By comparing the economics talent cultivation condition between China and foreign countries led by America and exploring the differences,as well as advantages and disadvantages of teaching and learning under the two systems,the problems existing in our economics talent cultivation can be found out,the weaknesses in teaching can be discovered,and specific suggestions can be raised for reference.


By extracting the beam with a bent crystal or by using an internal gas target, the multi-TeV proton and lead LHC beams allow one to perform the most energetic fixed-target experiments ever and to study $pp$, $p$d and $p$A collisions at $\sqrt{s_{NN}}=115$ GeV and Pb$p$ and PbA collisions at $\sqrt{s_{NN}}=72$ GeV with high precision and modern detection techniques. Such studies would address open questions in the domain of the nucleon and nucleus partonic structure at high-$x$, quark-gluon plasma and, by using longitudinally or transversally polarised targets, spin physics. In this paper, we will review the technical solutions to obtain a high-luminosity fixed-target experiment at the LHC and will discuss their possible implementations with the ALICE and LHCb detectors.


The Ni-Fe-Ga-Co system has been proposed as a new magnetic shape memory alloy due to its wide temperature range for martensitic and magnetic transformations (Tm and Tc , respectively) by changing composition. The alloy composition Ni52Fe17Ga27Co4 is more interesting for practical application due to its relatively high Tm and Tc. Here, martensitic transformations, crystal structures, and magnetic properties of Ni 52Fe 17Ga 27Co 4 alloys in form of bulk and powder are studied. Bulk samples were prepared by arc-melting followed by annealing at 1473 K for 4 h, while powder samples were filed from this bulk sample and annealed at 673 K for 0-15 h. The martensitic transformation present in the bulk sample totally disappears after powderisation. Tc of the powder sample is about 100 K lower than that of the bulk one. The saturation magnetization of the bulk sample (Msat = 54 emu/g) is reduced significantly down to 35 emu/g by powderisation, but increased again with increasing annealing time. After annealing the powder for 15 h, the martensitic transformation recovers and Tc is increased close to the level of the bulk sample. From room-temperature X-ray diffraction, it is found that the tetragonal non-modulated martensite in the bulk sample is completely transformed to a disordered fcc phase by powderisation, but gradually changes into a highly ordered L21 austenite phase during the subsequent annealing.


The process of designing and creating a new generation of transonic and supersonic wind tunnels is closely related to the development of efficient methods of the wall interference reduction. Along with the application of the permeable (perforated and slotted) walls, the possibilities of using alternative types of boundaries are investigated. One of the most promising approaches is generation of the homogeneous jet-boundary conditions on the solid walls of the wind tunnel test section using the near-wall jets or controlled boundary layer. Numerical simulation of a flow around the models with various test section boundaries has made it possible to substantially reduce the volume of the wind tunnel tests and to select optimal parameters of the boundary condition.


: Physical contamination of food occurs when it comes into contact with foreign objects. Foreign objects can be introduced to food at any time during food delivery and packaging and can cause serious concerns such as broken teeth or choking. Therefore, a preventive method that can detect and remove foreign objects in advance is required. Several studies have attempted to detect defective products using deep learning networks. Because it is difficult to obtain foreign object-containing food data from industry, most studies on industrial anomaly detection have used unsupervised learning methods. This paper proposes a new method for real-time anomaly detection in packaged food products using a supervised learning network. In this study, a realistic X-ray image training dataset was constructed by augmenting foreign objects with normal product images in a cut-paste manner. Based on the augmented training dataset, we trained YOLOv4, a real-time object detection network, and detected foreign objects in the test data. We evaluated this method on images of pasta, snacks, pistachios, and red beans under the same conditions. The results show that the normal and defective products were classified with an accuracy of at least 94% for all packaged foods. For detecting foreign objects that are typically difficult to detect using the unsupervised learning and traditional methods, the proposed method achieved high-performance real-time anomaly detection. In addition, to eliminate the loss in high-resolution images, the false positive rate and accuracy could be lowered to 5% with patch-based training and a new post-processing algorithm.

RMRS-GTR-117. Ogden, UT: U.S. Department of Agriculture, Forest Service, Rocky Mountain Research Station. 52 p. This report provides an assessment and compilation of recreation-related monitoring data sources across the National Wilderness Preservation System (NWPS). Telephone interviews with managers of all units of the NWPS and a literature search were conducted to locate studies that provide campsite impact data, trail impact data, and information about visitor characteristics. Of the 628 wildernesses that comprised the NWPS in January 2000, 51 percent had baseline campsite data, 9 percent had trail condition data and 24 percent had data on visitor characteristics. Wildernesses managed by the Forest Service and National Park Service were much more likely to have data than wildernesses managed by the Bureau of Land Management and Fish and Wildlife Service. Both unpublished data collected by the management agencies and data published in reports are included. Extensive appendices provide detailed information about available data for every study that we located. These have been organized by wilderness so that it is easy to locate all the information available for each wilderness in the NWPS.


Ricebean is a multipurpose grain legume crop mainly cultivated for food, fodder and green manure specifically by the poor farmers in the marginal areas of South Asia and South East Asia. It is mainly cultivated in India, China, Korea, Japan, Myanmar, Malaysia, Indonesia, Philippines, Java, Fiji, Bangladesh, Sri Lanka and Nepal. It is an important crop of Mid Himalayan region. In India its distribution is mainly confined to the tribal region of the North-eastern hills and the western and Eastern Ghats in peninsular region, often in hilly tracts. However its cultivation and production is limited and restricted to small and marginal areas. Therefore ricebean is regarded as underutilized crop. This underutilized crop has recently gained attention as an additional grain legume/pulse crop which keeps great potential to solve the food and nutritional problem. Since resource poor farmers in the marginal areas cultivate this crop, therefore it is directly related with the population who really suffers frequent food shortage and nutritional disorders.


The sector of local public service in Italy finally seems to be on the way towards liberalization, overcoming the difficulties which have hindered a real opening to competition and to markets in the last years. Indeed, the recent regulations contained in the so-called "liberalization decree" complete a long and tormented journey, providing a new and different role to the "public decision-maker", aiming at both regulating and organizing the initial stages of the process, such as the definition of the area of action of the activities under competitive tender, the identification of contract awarding criteria and of the ways to implement "contract changes" in agreements having long-term duration and which are hence subject to regulation' changes, technological evolution, cultural changes and anything affected by the passing of time. All the above indicated aspects require the public administration, too often used to limit its role to the mere control on legitimacy and regulatory appropriateness, to be able to detect and define community needs, turning them into service specifications and contract provisions under a logic of continuous adaptation to change. A difficult challenge, which however could represent a turning point for the advancement and motivation of the public sector.


Budker Institute of Nuclear Physics, Novosibirsk, Russia Abstract The time and spatial evolution of the light impurities emission is investigated by the VUV imaging spectrometer coupled with fast, 1 kHz, detection imaging system in plasma periphery in the CASTOR tokamak. Temporal measurements of the time behaviour of radial profile of the chord integrated line intensity are mostly performed in the spectral range of 90-130 nm. In a fixed tilting position of the spectrometer, the imaging of N V (123.8 nm), Lyc H I (121.6 nm) and O VI (103.2 nm, 103.7 nm) emission is created and analysed. The radial intensity profile indicates the sensitivity to the transport parameters, like diffusion coefficient D


At the macroeconomic level, the movement of the stock market index, which is determined by the moves of other stock market indices around the world or in that region, is one of the primary factors in assessing the global economic and financial situation, making it a critical topic to monitor over time. As a result, the potential to reliably forecast the future value of stock market indices by taking trade relationships into account is critical. The aim of the research is to create a time-series data forecasting model that incorporates the best features of many time-series data analysis models. The hybrid ensemble model built in this study is made up of two main components, each with its own set of functions derived from the CNN and LSTM models. For multiple parallel financial time-series estimation, the proposed model is called multivariate CNN-LSTM. The effectiveness of the evolved ensemble model during the COVID-19 pandemic was tested using regular stock market indices from four Asian stock markets: Shanghai, Japan, Singapore, and Indonesia. In contrast to CNN and LSTM, the experimental results show that multivariate CNN-LSTM has the highest statistical accuracy and reliability (smallest RMSE value). This finding supports the use of multivariate CNN-LSTM to forecast the value of different stock market indices and that it is a viable choice for research involving the development of models for the study of financial time-series prediction.


In this paper, we construct a [Formula: see text]-hypergeometric function by using the Hadamard product, which we call the generalized [Formula: see text]-hypergeometric function. Several properties, namely, convergence properties, derivative formulas, integral representations and differential equations are indicated of this function. The latter function is a generalization of the usual hypergeometric function, the k-analogue of hypergeometric function and other hypergeometric functions are recently presented. As an application, we obtain the solution of the generalized fractional kinetic equations involving of the generalized [Formula: see text]-hypergeometric function.


Combinatorial testing technique has been applied on Boolean-specification testing. Previous results indicated that it performed well to detect faults in Boolean expressions. This paper aims to investigate the reason why combinatorial testing works in Boolean-specification testing, which was always omitted previously. We design experiment to get the minimal failure-causing schemas for 19129 faults, which could be classified into 10 fault classes, of 20 Boolean expressions that extracted from TCAS system. By analyzing the number and strengths of minimal failure-causing schemas for each fault, the low bound of fault-detecting probability of τ-way combinatorial test suite for Boolean-specification testing are calculated. Computational results could explain the effectiveness of combinatorial testing technique in Boolean-specification testing.

An inner-variable integral theory was derived for solving incompressible two-dimensional turbulent boundary layers. This new derivation incorporated major improvements to the earlier inner-variable approach of White (1974) and Das and White (1986) by including a better wake function and a superior pressure gradient-wake correlation. Initially, the derivation from the first principle led to three nonlinear ordinary differential equations that must be solved simultaneously to yield important boundary layer parameters. Subsequently, to simplify the theory, it was systematically reduced in two steps: first to a two-equation method, and next to a one-equation method. Then comparisons were carried out among the three methods using well-established experimental data from a wide range of flows. The two-equation method gave the best overall performance and was selected as the standard method. Finally, it was tested against additional experiments, giving reliable predictions against eleven different experimental flows under diverse flow conditions.

In complex enterprises, various events such as failure of a server, malfunction of an application etc. may happen. In many cases, these events are caused by a change or an incident in a resource which belongs to another layer of information technology architecture. This makes the detection of complex events very difficult. In this paper, a mechanism is proposed based on pheromone deposition pattern for detecting the main source of failures and deficiencies in any position in the information technology architectural layers and recognising appropriate alternative solutions. It is expected that this mechanism facilitates the coordination between the resources which are not digitally represented. For sake of evaluation, two case studies are considered which investigate the inter-layer adaptation scenarios. The results show that the adaptation process can be done in less time and with more scalability with utilisation of the proposed mechanism in comparison with classic approaches.


Background Patients diagnosed with obstructive sleep apnea (OSA), who also consume prescription opioids, have a greater likelihood of morbidity and mortality. This study evaluated whether a primary care team, focused on chronic pain care management, could use a validated questionnaire (STOP-Bang) and motivational follow-up, to increase identification and treatment of OSA. Methods This study was a retrospective, dual arm, pre/post controlled study. Participants of this study included the complete chronic pain management sub group treated by this primary care team. Participants were ≥ 18 years old and prescribed daily opioids for treatment of chronic pain. All participants had a multifaceted, individualized, educational meeting that included completing a STOP-Bang questionnaire. Participants who received a score ≥ three were advised to follow up with their primary care physician. Participants were seen quarterly throughout the study. Results The primary outcome of this study was that 65% of participants with likely OSA were using CPAP for a minimum of 12 months (range of 12–25 months, 18-month average) post-intervention vs. 37% CPAP-use in the control group (12 months of observation), both groups were chronic opioid users with OSA. This was a 28% relative improvement (p = 0.0034). A secondary outcome was that 8.9% of non-prior CPAP users obtained CPAP post- intervention; a 56.7% pre-post improvement (p = 0.0064, x2 = 10.08 with 1 degree of freedom). Also, participants who were likely to have OSA (STOP-Bang score ≥ 3 or had a positive polysomnography (AHI >5 with comorbidities)) compared to those unlikely to have OSA (STOP-Bang score <3 or had a negative polysomnography (AHI <5)) in this study were more likely to be male, have a higher BMI, have hypertension, have cardiovascular disease and/or have diabetes (all types). Conclusion Team based care management for participants taking prescription opioids, where STOP-Bang questionnaires were completed, were associated with an increase in the identification and treatment of OSA.


Roumak Extra (RE) supplement was prepared from Soha Aghrin Tech Co (Tehran, Iran). Material and method: At day of birth, thirty Holstein suckling calves were randomly assigned to 3 treatments with 10 calves in each group from 3 through to 60 days of age. Treatments were: (1) CON (no additives), (2) LMV (addition of 15 grams of RE supplement per liter of milk), (3) HMV (addition of 25 grams of RE supplement per liter of milk). Whole milk was fed to calves at two meals at 09:00 and 17:00. In all treatments same starter (20% protein and 3.3 Mcal/kg metabolizable energy) were fed to calves. Calves had free access to starter and water from the beginning of the experiment. Whole milk was fed to calves at two meals at 09:00 and 17:00. Calves had free access to starter and water from the beginning of the experiment. Data were analyzed by mixed procedures of SAS (9.1) software. Treatments had no effect on body weight changes and daily weight gain of calves (P˃0.05). Calves fed vitamin-mineral supplement (LMV and HMV) consumed less starter than CON calves (p <0.05). Also, the length of starter intake in the CON group was higher than the LMV and HMV calves (p <0.05). Dry matter digestibility increased (P˂0.05) in LMV and HMV in compared to CON group. Conclusion: Conclusion: Conclusion: The final weight and daily weight gain of the calves on supplemented treatments were same with control group indicating an improvement in the feed conversion ratio and nutrients digestibility.


Resistance of 188 isolates of B. cinerea, collected from several counties in Shanxi Province, to MBC was tested. The results showed that average EC50 and EC90 values of sensitive isolates were 0.0428μg·mL-1 and 0. 1280μg·mL-1 ,that those of middle resistant isolates were 11. 2415μg·mL-1 and 128. 4351μg·mL-1. Resistance ration of middle resistant isolates was 262. 7 fold. Due to high resistance of most resistant isolates, EC50 values were unattained. It demonstrated that EC50 values were over 50μg·mL-1, EC50 values of most resistant isolates were higher than 100 fold, extreme ones reached 500μg·mL-1, namely, resistance ration was over 1000 fold. Resistance of isolates of B. cinerea to MBC was relatively high in region of Shanxi Province, resistance frequencies in Jinzhong, Jinnan, Jindongnan and Jinbei were 86%, 87.2%, 93.5% and 100% respectively, high level resistance frequencies were over 50% except Jinbei isolates (33. 3%). In terms of resistance in various regions, Jinnan and Jindongnan were higher relatively and lower in Jinzhong and Jinbei.

The iPS efficient induction method is of great significance for improvement of the iPS technology safety and application of the iPS in the regenerative medicine field.


A recent study from the Mayo Clinic documented the here to fore unknown fact that symptoms of lateral epicondylitis persist for 6 months in about 20% of patients with this problem [1]. Further, in that cohort of the 20% of patients still experiencing continued pain, the mean time to resolution was an additional 24 months (Figure 1). These observations prompted the investigators to define chronic refractory epicondylitis as a condition persisting for more than 6 months despite appropriate treatment. Furthermore, a review of the ICD codes employed in 2013 in the United States included over 30 million with a diagnosis of chronic tendinopathy or fasciitis. While the burden of the disease is considerable, there is wide divergence in the literature regarding the optimum treatment of the chronic refractory condition.


Abstract The effect of nitrogen application (0, 25, 50, and 100 kg N/ha) on spring and autumn pasture yield was measured on the West Coast. All rates of nitrogen application increased dry matter production; the average pasture yield response was 360-1080 kg DM/ha in the spring and 120-510 kg DM/ha in the autumn. Spring responses were highest from September applications. March and April were the best months for autumn applications but responses were smaller and less reliable than from applications in the spring.

A SURVEY of numerous studies concerned with the experimental production of vitamin E deficiency reveals a rather wide variation in the time necessary to induce sterility in rats of either sex. In male rats reared from weaning on vitamin E-deficient diets, the time of experimental feeding necessary to produce degenerative changes in the germinal epithelium may vary from 50 days or less [Mason, 1926; Ringsted, 1936] to 90-150 days [Evans & Burr, 1927; Kudrjaschov, 1930; Juha'sz-Schaffer, 1931]. It has also been the experience of many investigators that a variable proportion of female rats reared on vitamin E-deficient diets will complete one or more pregnancies before exhibiting a resorptiongestation typical of vitamin E depletion. This variable occurrence of initial fertility has proved particularly annoying and time-consuming in the preparation of rats for the bio-assay of vitamin E, and has necessitated the production of a proven resorption in all rats prior to their use in assay tests. Attempts to eliminate the occurrence of this phenomenon by the use of slightly rancid fat in the hopes of destroying possible traces of vitamin E in the experimental diets used have not proved particularly effective. Furthermore, such a procedure seems highly undesirable in view of the observations [Kudrjaschov, 1935] that products of a ketone nature formed in rancid fats are capable of preventing implantation in rats and may even cause resorption of the foetus if implantation is successful. Proper limitation of the vitamin E content of the diet supplied to mothers whose offspring are to be selected for vitamin E deficiency studies appears to be a much more successful and acceptable method for elimination of initial fertility [Ringsted, 1936], but its general applicability is limited by the care and expense involved in the preparation of stock diets containing a uniformly low content ofvitamin E. More recently, Bacharach et al. [1937] report the occurrence of resorption-gestations in the first pregnancies of96 out of 104 vitamin E-deficient rats examined prior to 1937, and in 100% of 316 rats tested since that time, but fail to mention the extent to which the lactating young had access to the maternal diet or the composition of the latter. Although it has been rather generally accepted that the vitamin E reserves of young rats and the variable response of the latter to vitamin E depletion are significantly influenced by the vitamin E content of the maternal diet, no effort has been made to evaluate the mechanisms concerned. The present communication deals with an attempt to determine to what extent the vitamin E reserves of newly weaned rats are due to direct consumption of the maternal diet as the young adopt free-eating habits during the latter part of lactation, and to what 1 This investigation was aided by a grant to Vanderbilt University School of Medicine from the Division of Medical Sciences of the Rockefeller Foundation, and by a special grant for technical assistance from the American Academy of Arts and Sciences.


This article explores how infrastructure networks get created in spite of the uncertainties in their development process. It focuses on the development of the Iowa Communications Network and North Carolina Information Highway which represent two very different models of state-wide networking. The experience with the Erie and Welland Canals provides the backdrop for the analysis. It offers insights into how metaphors provide the initial impetus, and how political will and sunk investments help sustain the effort for creating an infrastructure network.


The article tackles the problem of dynamic linguistic changes in communication on the material of phraseological units and metaphors. A phrase-structure analysis of German phraseological units shows the importance of praseological motivation in producing predicative signs of phraseological nature. It is also proved that each new sign develops along with a metaphoric sentence. Both predicative signs perform the functions of linguistic economy, informativity and evaluation.


The effect of the driving forces which arise during the absorption of energy from rf waves by a plasma on diffusive expansion is analyzed. The radial drift of the particles in the field of these driving forces is superimposed on the diffusion flux. The sign of the drift component depends on the direction of the wave phase velocity and can be chosen beforehand. This circumstance makes it possible to control the diffusion. The power absorption required for complete cancellation of the diffusive expansion is estimated.


In this paper, a wideband circularly-polarized spiral antenna is proposed to be used for CubeSat application. The antenna covers two of CubeSat frequencies; the S-band (2.2 GHz) and X-band (8 GHz). The proposed antenna belongs to the wideband and frequency-independent antenna category, which are known to provide a constant radiation pattern, impedance and polarization throughout the whole bandwidth. The performance of the spiral is compared in two different conditions; in free space and above a ground plane with a separation distance of λ/4 at the operating frequency of 2.2 GHz and 8 GHz. The spiral above the ground plane exhibits a unidirectional radiation and higher gain with an increase of 26.6% (2.2 GHz) to 34.6% (8 GHz) than the free space spiral. Moreover, the return loss also managed to stay within the ideal limit of S11<-10dB (-19.528 dB at 2.2 GHz, and -21.92 dB at 8 GHz) and exhibits circularly-polarized radiation with low axial ratio<3 dB (0.78 dB at 2.2 GHz, and 0.89 dB at 8 GHz).


There is one specific reason for a person to learn a foreign language, and it is for it to be useful to their own specific needs. For that to happen, learners need classes where significative learning is produced. This is why we consider our workshop to be very pertinent, since we plan to give English Language Teachers an innovative perspective on the subject to create educational material. The main objective of this workshop is to provide the audience with a starter idea on how to create a resource for the EFL classroom to generate significative learning in the students by using their sense of touch. With this, we want educators to start thinking on how to create new resources to use in the English Language classroom for the learning experience to be significative to the students. At the beginning, a presentation will be given, with its main objectives and the reason why this sensorial kind of materials are needed. Afterwards, the process and the materials needed to come up with this educational resource, will be explained. To conclude, the presenters will explain the benefits this resource produces in learners. At the end of this workshop, the audience is expected to have knowledge on how to create a board with several elements to explain adjectives; adding, how to apply this resource into their English classes; and finally, to be able to identify the reasons why, this type of resources are necessary to be implemented in the classrooms for the learners progress.

A method for separating /sup 233/U from irradiated thorium dioxide is presented in which the thorium dioxide changes to thorium sulfate when heated in H/sub 2/S0/sub 4/ (H/sub 2/0/sub 2/) solution. The thorium sulfat e is practically insoluble in this solution, while the /sup 233/U leaches out into the solution as U(VI). (DHM)


Different measures, including placing children in the rear seats of vehicles and the use of age-appropriate restraints have been developed to reduce injuries among children during a motor vehicle crash. Many of these measures are not universally adhered to. This cross-sectional, observational study was accordingly conducted to describe child seating position and restraint use in the Ibadan Metropolis, south western Nigeria. Observations were made at selected primary school gates in 3 of the 5 Local Government Areas (LGAs) which make up the metropolis.
Data on 796 children riding in 440 vehicles were collected. Driver restraint use was 48.0%. Restraint use among the children was 4.1%. Two hundred and twenty-three (28.0%) children between the ages 0-13 years were seated in the front, most, 86 (38.6%) of whom were aged 1-4 years. Just under a half (48.3%) of restrained drivers had at least one child seated in the front of the vehicle compared to 47.6% of unrestrained drivers. Children were more likely to be seated in the front when the rear seat was unoccupied. In addition, children were more likely to be restrained when riding in a vehicle with a restrained driver. There is an urgent need for multi-disciplinary action geared towards improving child passenger safety practices in the Ibadan metropolis. Legislation, health education and availing affordable child restraints will go a long way towards ensuring the safety of children in motor vehicles.

It is well known that inferential errors can induce nice but provocable strategies to engage in vendettas with each other. It is therefore generally believed that imperfect monitoring reduces the payoffs of such strategies and impairs the evolution of cooperation. The current literature, however, only scrutinizes specific strategies, either analytically or in particular tournaments. This article examines in a more general way how monitoring uncertainty affects the fate of cooperation in tournaments of the iterated prisoner's dilemma (IPD). The first set of results shows that imperfect monitoring does create a sharp trade-off between cooperativeness and unexploitability. The second set examines how random shocks affect the tournament payoffs of several large classes of strategies in the IPD, and shows how noise can help certain nice strategies. The third set analyzes how imperfect monitoring can facilitate the emergence of cooperation based on a population of non-nice strategies. Thus the idea that inferential uncertainty always harms nice strategies and always impairs the evolution of cooperation must be sharply qualified.


THE microscopical examination of random stools for the presence of increased amounts of fat has proved to be a valuable screening procedure in the detection of malabsorptive syndromes in this laboratory. Although questioning the accuracy and reproducibility of such estimates of fat by microscopy, Weijers and van de Kamer1 gave data that indicate the clinical usefulness of this procedure, which in their hands showed an error of only 11 to 14 per cent. Their results suggest to us that even with the error noted by them the method could be a valuable screening technic. Because of heightened interest in the . . .

Key Points Question After red blood cell (RBC) transfusion, does tissue oxygen saturation vary depending on degree of anemia, and is cerebral saturation associated with neurodevelopmental outcomes? Findings In this secondary analysis of the Transfusion of Prematures (TOP) randomized clinical trial, mean cerebral saturation (Csat) and mesenteric saturation (Msat) were significantly increased after RBC transfusion in 2 hemoglobin threshold groups, with no statistical difference in the magnitude of increase between groups. Mean pretransfusion Csat less than 50% occurred more frequently in infants who died or developed neurodevelopmental impairment at 22 to 26 months corrected age. Meaning The findings indicate that increases in Csat and Msat are associated with RBC transfusion and that Csat may be a useful target for improving survival without neurodevelopmental impairment in infants with various degrees of anemia.


The productivity of Kittiwake ( Rissa tridactyla ), Guillemot ( Uria aalge ) and Fulmar ( Fulmaris glacialis) was surveyed at six sites on Lundy in 2010. Average Kittiwake productivity was 0.67 per pair, average Guillemot productivity 0.68 and average Fulmar productivity 0.52. Increases in productivity were noted for all species in comparison to previous years.


A comprehensive analysis of the resolution effects of a cross-wire probe for velocity measurements is presented. The results, which are obtained from DNS of isotropic turbulence and from a model spectrum of the turbulent kinetic energy, consider different lengths of the wires, separations between the wires, as well as time sampling rates of the velocity signal. The impact of the resolution is estimated on several quantities, such as the velocity variance, the velocity derivative variance and some isotropy estimators. In general, the lack of resolution has a larger effect on the statistics of the velocity derivatives. However, it is found that a particular surrogate of the kinetic energy dissipation rate remains relatively unaffected even when the separation between the wires is large. Further, the correction factors derived from the model spectrum systematically overcorrect the underresolved measurements.


The importance of research and development (R&D) and innovation at a national level is well established. Both are perceived to be essential contributors to future national productivity and economic performance.


The basic approach to the problem of torsional fatigue strength of pieces containing defects is based on the stress concentration factor concept. However, experiments have shown that the torsional fatigue limit of specimens containing small holes is controlled by the threshold condition for small cracks emanating from small notches. Therefore, the ratio of torsional to bending fatigue limit (τw /σw ) for specimens containing small defects must be studied from the viewpoint of fracture mechanics.

The scope of this paper is to address the calculation of the stress intensity factor for a small crack emanating from a three-dimensional hole under a biaxial state of stress by using the weight function method and to apply it to the fatigue limit prediction. The results obtained are in good agreement with experimental results on specimens with defects.

The aim of this study is to computationally estimate local magnetic fields from evoked axons to support previously reported experimental evidence of direct neuronal detection (DND) of axonal firing using magnetic resonance imaging (MRI) [1] [2]. The hypothesis tested is that the fields resulting from the electrical activity of axons can perturb the main field of the scanner, thereby producing visible image artefacts so that direct imaging of brain functioning may be possible. In this work magnetic fields are calculated for multiple axons using a hybrid model of the electro-physiological parameters of the human optic nerve and a complete 3 dimensional solution of the differential form of Poisson's equation.


This paper aims to study the 'economics made fun' literature with regard to its main purpose: popularizing economics. We shed an historical light on such literature by showing that its main strategy for introducing economics to non-specialists had already been tried in the 1970s in what were described as "issues-oriented" textbooks. We show that both literatures, as introductory enterprises, were responses to similar challenges. The first one is the problem of economic illiteracy, a problem that has concerned teachers in economics since the early 1960s. Both literatures did offer an interesting response to perceived shortcomings of introductory courses. The second challenge came from the attacks on economics and its teaching for their lack of relevance. We explore how the notion of relevance evolved in time and how both literatures attempted to respond to the criticisms of their time accordingly. By addressing these questions, our study explores how economists used these introductory enterprises to disseminate a certain image of them and their discipline in comparison to other social scientists and non-specialists, and how these representations evolved in time.


A national survey of approximately 570 mainly undergraduate institutions has shown that only a few offer specific courses on the history of chemistry. Considerably more offer the history of science, usually within other departments such as a Department of History. The inclusion of some history within regular chemistry courses is quite common, with coverage varying from slight to extensive. While a lack of time prohibits most modern chemical curricula from including a specific history of chemistry course, about five institutions were studying or planning such an addition.

Space systems miniaturization has been increasingly popular for the past decades, with over 1600 CubeSats and 300 sub-CubeSat sized spacecraft estimated to have been launched since 1998. This trend towards decreasing size enables the execution of unprecedented missions in terms of quantity, cost and development time, allowing for massively distributed satellite networks, and rapid prototyping of space equipment. Pocket-sized spacecraft can be designed in-house in less than a year and can reach weights of less than 10g, taking away the considerable costs and requirements typically associated with orbital flight. However, while Systems Engineering methodologies have been proposed for missions down to CubeSat size, there is still a gap regarding design approaches for picosatellites and smaller spacecraft, which can exploit their potential for iterative and accelerated development. In this paper, we propose a Systems Engineering methodology that abstains from the classic waterfall-like approach in favor of agile practices, focusing on available capabilities, delivery of features and design "sprints". Shifting away from the typical design-verify-operate model, this method originates from the software engineering discipline, focusing more on short design iterations, team collaboration, and focusing on quickly delivering a minimum viable product. This allows quick adaptation to imposed constraints, changes to requirements and unexpected events (e.g. chip shortages or delays), by making the design flexible to well-defined modifications. Two femtosatellite missions, currently under development and due to be launched in 2023, are used as case studies for our approach, showing how miniature spacecraft can be designed, developed and qualified from scratch in 6 months or less. Both missions involve the attachment of a chip-sized satellite ("ChipSat") into a larger spacecraft, either relying on their host for communications and power or being completely independent. We claim that the proposed method can simultaneously increase confidence in the design and decrease turnaround time for extremely small satellites, allowing novel and unprecedented missions to take shape without the overhead traditionally associated with sending cutting-edge hardware to space.


Raunkiaer (1934) defined the life form of a plant by the position and degree of protection of its perennating bud. His system provided a means of classifying floras that focused on the natural selection of vegetative organs in response to environmental pressures and the ultimate morphological adaptations that enable the plant to survive unfavorable conditions.


This study aimed to investigate the relationship between interleukin‐6 (IL‐6) and NS5ATP9 in autophagy of liver cancer cells. Autophagy is one of the important regulators of the replication of hepatitis C virus and the survival of tumors. IL‐6 is a multifunctional cytokine that plays an important role in autophagy and development of many kinds of tumors. However, the role of IL‐6 in autophagy has not been fully explored. A previous study had shown that a novel gene, NS5ATP9, could modulate autophagy. The present study demonstrated that human IL‐6 recombinant protein induced autophagy of HepG2 cells. Conversely, autophagy decreased after IL‐6 was silenced or neutralized with monoclonal antibody against human IL‐6. In addition, NS5ATP9 was upregulated by IL‐6 via nuclear factor–kappaB activation, as detected by Western blot. Further studies indicated that the induction of autophagy by IL‐6 could be attenuated by silencing NS5ATP9. Interestingly, the expression of NS5ATP9, in turn, resulted in the upregulation of IL‐6. In conclusion, IL‐6 could induce autophagy by expressing NS5ATP9, while NS5ATP9 upregulated IL‐6 levels in turn, which further induced autophagy.


Objective: Oral anticoagulation therapy (OAT) with warfarin increases mortality and disability after intracerebral hemorrhage (ICH), the result of increased ICH volume and risk of hematoma expansion. We investigated whether OAT also influences risk of development of intraventricular hemorrhage (IVH), the volume of IVH and IVH expansion, and whether IVH is a substantive mediator of the overall effect of OAT on ICH outcome. Methods: We performed a retrospective analysis of a prospectively collected single-center cohort of 1,879 consecutive ICH cases (796 lobar, 865 deep, 153 cerebellar, 15 multiple location, 50 primary IVH) from 1999 to 2009. ICH and IVH volumes at presentation, as well as hematoma expansion (>33% or >6 mL increase) and IVH expansion (>2 mL increase), were determined using established semiautomated methods. Outcome was assessed at 90 days using either the modified Rankin Scale or Glasgow Outcome Scale. Results: Warfarin use was associated with IVH risk, IVH volume at presentation, and IVH expansion in both lobar and deep ICH (all p < 0.05) in a dose-response relationship with international normalized ratio. Warfarin was associated with poor outcome in both lobar and deep ICH (p < 0.01), and >95% of this effect was accounted for by baseline ICH and IVH volumes, as well as ICH and IVH expansion. Conclusion: Warfarin increases IVH volume and risk of IVH expansion in lobar and deep ICH. These findings (along with effects on ICH volume and expansion) likely represent the mechanisms by which anticoagulation worsens ICH functional outcome.


Published in: Phys. Rev., C 66 (2002) 065801 citations recorded in [Science Citation Index] Abstract: We investigate $K^-$ and $bar K^0$ condensation in $beta$-equilibrated hyperonic matter within a density dependent hadron field theoretical model. In this model, baryon-baryon and (anti)kaon-baryon interactions are mediated by the exchange of mesons. Density dependent meson-baryon coupling constants are obtained from microscopic Dirac Brueckner calculations using Groningen and Bonn A nucleon-nucleon potential. It is found that the threshold of antikaon condensation is not only sensitive to the equation of state but also to antikaon optical potential depth. Only for large values of antikaon optical potential depth, $K^-$ condensation sets in even in the presence of negatively charged hyperons. The threshold of $bar K^0$ condensation is always reached after $K^-$ condensation. Antikaon condensation makes the equation of state softer thus resulting in smaller maximum mass stars compared with the case without any condensate.


In the present paper, the estimation of limit unit bearing capacity qbL of axially loaded circular footings on sands based on cone penetration test cone resistance qc is examined. There are significant uncertainties in the calculation of bearing capacity using the bearing capacity equation. The selection of the value of the soil friction angle f and of the equation for Ng accounts for much of the overall uncertainty. The approach proposed in this study can reduce the uncertainties associated with the bearing capacity equation, as no estimation of f or selection of an equation for Ng is necessary. Instead, normalized limit unit bearing capacities qbL/ qc are calculated from non-linear finite element and cone penetration resistance analyses for various soil and footing conditions. Effects of the relative density DR, the lateral earth pressure ratio K0, and the footing size are also addressed. It is observed that the normalized limit unit bearing capacity qbL/ qc decreases as DR increases and that this rate of decrease of qbL/ qc varies with K0. Values of qbL/ qc are presented both in equation form and in charts. The values of normalized allowable unit load qb,all / qc at a settlement of 25 mm for various soil and stress states are also provided.

A demonstration was created to display the unique behavior of a familiar element, phosphorus, and to make chemistry more accessible to the introductory student. The common allotropes of phosphorus and their reactivity are discussed. In this demonstration, the white allotrope of phosphorus is synthesized from the red phosphorus obtained from a matchbook. White phosphorus is exposed to oxygen in the air, and an eye-catching flame is produced. This simple, effective, and dramatic demonstration shows the conversion between red and white allotropes of phosphorus, its reaction with oxygen to form phosphorus oxides, and hydrolysis to form phosphoric acid. Care has been taken to minimize the hazards of burning white phosphorus and to identify proper methods of disposal.


From March 10 to April 5 of 1988, there were five obvious acts of cold air which intruded into provinces of Guangdong and Guangxi in China, and formed precipitations of cold front. In order to determine the directions of dry and wet strealines with acidific pollutant in upper air and bottom layer when the acid rains were formed, author analysed streamline fields of different layers which are 500hpa, 700hpa, 850hpa and ground level. Acidity and electric conductivity of precipitation were observed in ground stations of Guangzhou and Guilin and mountain stations of Miaoer Mountain, Shizi Mountain and Baiyun Mountain stations have different heights. Meanwhile, aircraft sounding of acidity and electric conductivity of cloud water were implemented in the Liangguang's area, taking the bases as Guangzhou and Guilin airports. We knew that the characteristics of acidity and electric conductivity of cloud and rain in the same process of precipitation of different areas and altitudes, and the changes of these parameter's in the different processes of precipitation.


The BIRD pulse sequence is widely used to distinguish between protons that are directly bonded to a 13C nucleus and those that are not. It consists of a proton 90° pulse, a delay of 1/(21JCH), simultaneous carbon and proton 180° pulses, a further delay of 1/2J and a final proton 90° pulse. For two spins at equilibrium, the effect of this sequence can be easily understood, but for complex systems the behaviour can be counter‐intuitive. This paper explains the general behaviour of the BIRD sequence using theoretical equations and numerical simulations, and discusses some practical applications of the BIRD pulse train. The theoretical equations are derived using tables of general behaviour for the spin systems AX, AX2 and AX3. The tables allow the exact calculation of the effect of any pulse sequence on these spin systems, including all multiple quantum effects. The simulations show that the sequence is usually robust with respect to pulse imperfections and non‐ideal spin systems. In other cases, particularly when signals should be suppressed, small errors can have dramatic consequences. The results derived here are for a BIRD sequence inserted into an INEPT experiment, but many of the conclusions can be applied to all of the more standard applications of the BIRD.


This study involving 60 Japanese learners of English investigated the effects of various kinds of form-focused instruction on learners' ability to comprehend and produce polite requests in English. Each treatment group received one of the following: (a) deductive instruction; (b) inductive instruction with problem-solving tasks; or (c) inductive instruction with structured input tasks. These tasks all involved explicit input-based instruction and were intended to test for differences in deductive versus inductive treatments. Treatment group performance was compared with that of a control group on a range of input- and output-based pretests, posttests, and follow-up tests. The results indicate that the three treatment groups performed significantly better than the control group, suggesting that in this study explicit input-based instruction was effective both deductively and inductively for learners' comprehension and production of English polite requests. There was also some indication that
inductive treatment may be superior in the longer term.


Objective: Reduced (L) Vit D (D) and high (H) uric acid (U) levels have been associate with increased cardiovascular risk. Aim of the study was to highlight their association with the subclinical vascular damage in untreated recently diagnosed very mild hypertensives with a similar number of metabolic syndrome factors (nATPIII). Design and method: By medical visit and identification of the metabolic syndrome factors, 238 very mild hypertensives (136 ± 15/84 ± 9 mmHg), 62 controls with normal (N) D and U, 96 with LD, 40 with HU and 40 with both the conditions (LDHU) with similar metabolic assessment, underwent measures of carotid-femoral pulse wave velocity (PWV), ankle-brachial index (ABI), carotid intima-media thickness (IMT), as indices of functional and structural arterial damage, and videocapillaroscopy of the middle and distal phalangeal skin of the 2nd, 3rd and 4th finger of the non-dominant hand during baseline (CAP) and venous congestion (CVC) obtaining capillary recruitment (REC) as indices of functional and structural microcirculatory damage. Results: Patients showed a similar hypertensive state during the medical visit and ABPM but different capillary indices. (m ± s:d.*:p<.05, **:p < .01, ***:p < .001 vs NDNU; °:p < .05, °°:p < .01, °°°:p < .001 vs LDNU;^p < .05, ^^:p < .01, ^^^:p < .001 vs NDHU). Figure. No caption available. Pearson analysis showed the association between Vit D and CVC (.440*) and REC (.335***) in LDNU and with CVC (631***) and REC (.666*) in LDHU as well as between U and CAP (-.470*) in NDHU and (-606*) in LDHU. Conclusions: The results suggest that, in very mild hypertensives with metabolic syndrome, reduced Vit D is associate to structural microvascular damage before the onset of structural or functional macrovascular impairment. Hyperuricemia show a lower microcirculatory damage but this is amplified in patients with both the disorders (LDHU),


The light-weight magnesite-alumina spinel refractories was synthesized by the way of one step sintering, and the effect of the light magnesia powder and the alumina powder addition on its sinterability was studied. The results showed that the sinterability of magnesite-alum- ina spinel could be improved by the addition of light magnesia powder and alumina powder. Furthermore, the performance of refractory with the light magnesia powder is better than that with the alumina powder.


Let f and g be polynomials of degrees p and q respectively over a noetherian ring A (with p > q). If the polynomial g is monic then we know whether g divides f or not. Otherwise, we have no means to solve this problem. In this paper, our purpose is to give conditions on the coecients of f and g for divisibility of f by g. Using the result, we will obtain conditions of irreducibility of any polynomial. This result can be extended to polynomials over a commutative ring. We follow ideas of S. S. Woo.

The Dynamic Window Approach (DWA) suffers from unreasonable planning or is prone to obstacle avoidance failure when the mobile agent operates in a complex environment with dense obstacle distribution. An improved DWA path planning algorithm (IDWA) is proposed to address the above problems. Firstly, the heading angle function is modified to improve navigation ability for mobile agent reaching at the target point while ensuring operational safety. Secondly, the obstacle function is optimized to avoid the agent going around the obstacle's edge. Finally, a complex scenario with multiple obstacles of different passing difficulties is constructed to verify the feasibility of the proposed method. Simulation experiments show that IDWA significantly improves the agent's passage efficiency and local search ability, and the path planning is more reasonable with smaller path deviation and heading deviation.


A thyristor valve for HVDC transmission insulated by compressed SF6 gas has been developed. The valve is cooled by the forced circulation of the insulating gas with a blower. Valve unit up to the voltage and current ratings of 250 kV and 3,000 A can be housed in a metal tank and the valve is transportable on a trailer fully constructed. A metal enclosed converter for 500 kV HVDC power transmission for example, may be constructed by connecting the units to form a twelve pulse converter.


The creators of Place Lab, a location-enhanced mobile computing system, share lessons learned about leading the project and real-world deployment. Place Lab lets a device estimate its location by scanning for fixed radio beacons, such as nearby 802.11 access points and GSM (Global System for Mobile Communications) cell towers and referencing the beacons' positions cached in the mobile device's database. Place Lab devices can access the wigle.net community Wi-Fi data base, which increases coverage to almost six million beacons worldwide. We also investigated how to bootstrap a beacon database from a partial database and keep it fresh as beacons are added or moved. The Place Lab approach of running on commodity devices, using existing infrastructure, and supporting existing applications resulted in a location technology that is practical for deployment in the real world. The core idea of the beacon-location approach was even commercialized twice during the life of our project, and Place Lab was occasionally criticized as being too practical for good research. We argue, however, that Place Lab is an example of how commercializable ideas can lead to high-impact research projects


The purpose of this study was to investigate the effect of robot-assisted upper limb rehabilitation training on hand and upper limb function in children with Moya-Moya disease.
The intervention method used InMotion®RM, an upper limb-assisted rehabilitation robot, and the evaluation was conducted once each pre- and post-assessment, and the treatment was conducted 10 times for 30 minutes, a total of 12 sessions. The functional movement of the upper limb and hand was evaluated using the Jebsen-Taylor Hand Function Test and the program inherent in the InMotion®RM. The results were compared through a visual analysis using tables and graphs.
After the training, the Jepson-Taylor Hand Function Test score improved in all areas, compared to the baseline. Evaluation using the program inherent in InMotion®RM showed improvement in the smoothness, accuracy, efficiency, and stability of upper limb movement.
The results of this case study suggest that robot-assisted upper limb training is applicable to children with Moya-Moya disease and that it has a positive effect on improving the function and stability of the upper limb. In the future, more research subjects will be needed to study the method and effectiveness of robot-assisted upper limb training through group research.


A facile and convenient approach for the synthesis of multi-functionalized calix[4]arenes through multi-component reactions is described. A series of five new calix[4]arene-hexaamide derivatives were synthesized, and their structures were elucidated by means of spectroscopic data. The value of this method lies in its operational simplicity, mild reaction conditions, structural diversity of products, and good yields. Furthermore, fluorescence studies demonstrated considerable binding affinity of these new calix[4]arenes toward β-lactoglobulin protein.


The volume of rubbish in the city of Jakarta was getting more and more days, garbage must be transported every day from various points of the location to garbage collection sites or garbage cans. A large number of garbage collection pointed that accumulate and cause pollution plus the lack of waste management resources by the government would have an impact on the environment and the surrounding community from air pollution to the emergence of diseases that arise from the rubbish pile. The author raised this issue to build an internet of things waste early warning systems to improve effective and time-efficient waste management resources. Early detection systems for smart bins could be applied in big cities so that they made a big contribution to maintaining a clean and comfortable community environment as a form of smart city development.


The precision and accuracy of acoustic instrument calibrations is fundamental in ensuring the validity and defensibility of acoustic measurements. The measurement error is additive to the overall uncertainty or error associated with acoustic calculations and modelling techniques, where these rely on measurement data as a source of acoustic data. Therefore, the tolerance of the calibration is a fundamental component in determining the accuracy of all applications that rely on acoustic measurement data. National and International metrology standards define the methodologies adopted in acoustic calibration. Currently the IEC 61672 standard is adopted for the periodic testing of field instruments. This paper provides an overview of the changes in calibration requirements of the IEC 61672 standard relative to the earlier versions of IEC 61672 and the IEC 652 standard. The paper then explores in more detail from an end user perspective the implications of calibration methodologies and the overall accuracy of acoustic data.


Summary Extensive habitat modifications within the Mississippi and Missouri rivers have presumably interfered with the reproductive isolating mechanisms between the endangered pallid sturgeon, Scaphirhynchus albus, and the sympatric shovelnose sturgeon, Scaphirhynchus platorynchus, causing hybridization between these two species. Several character indices were developed to assist fisheries biologists in identifying specimens of S. albus, S. platorynchus, and their putative hybrids. The indices have numerous assumptions, including that pure strains of both parental species are within the sample analyzed and that hybrids are morphologically intermediate relative to their parents. If these indices have produced inaccurate identifications, then previous work on Scaphirhynchus studies in the Mississippi and Missouri rivers are questionable, including status surveys, captive propagation efforts, or the harvesting of tissues for genetic studies. In this study we tested indices by examining progeny of known pallid, shovelnose, and hybrid sturgeon propagated, raised, and preserved at hatcheries. These 60 specimens [78–600 mm standard length (SL)] were propagated with breeding stock from the upper Missouri River drainage, where hybridization between these two species presumably does not occur. Existing indices did not correctly identify small ( 250 mm SL) sizes of S. albus, S. platorynchus, and their hybrids. Indices worked fairly well in identifying large S. platorynchus, but not in differentiating large S. albus from hybrids. We used principal components analysis (PCA) as an alternative approach to character indices. No a priori knowledge of the identity of the specimen is required with this multivariate technique, which avoids potential circular reasoning present in indices. We were able to completely or almost completely separate both sturgeon species and their hybrids by extracting principal components from a correlation matrix of 13 meristic characters in a standard PCA and extracting size-corrected principal components from a covariance matrix of 51 morphometric variables using a sheared PCA. Additionally, we demonstrated that first generation hybrids were intermediate with respect to their parental species. Multivariate analyses with a reduced character set of six meristic and 12 morphometric variables also led to accurate and reliable specimen identification. Head spines and numerous qualitative characters are also extremely useful in differentiating between Scaphirhynchus species and their hybrids. In addition to all morphometric characters, some meristic characters and the degree of head spine fusion vary significantly with SL of sturgeons. Recording appropriate data from released specimens, including photovouchers, and making this information available is essential for researchers to have any scientific or legal basis for genetic or any other studies involving these sturgeons.


This paper spotlights the application of the water cycle algorithm (WCA) optimized fractional order (FO) PID (FOPID) controller for regulating the frequency of interconnected power systems (IPS). A dual area hydro-thermal (DAHT) system with geothermal power plant (GTPP) integration in area-1 is considered and put forward the investigation upon laying the perturbation of 10% step load (SLP) on area-1. However, the efficacy of the presented FOPID controller is revealed with the performances of PI, PID, PID plus double derivative (PIDD). Further territory control approach of supercapacitors (SCs) and Thyristor controlled series compensator (TCSC) is established in this work to attain performance improvement under significant load perturbations. Simulation results reveal the improvement in IPS dynamical behaviour with the presented control strategy. At last, the robustness of presented secondary and territory mechanisms is validated by conducting the sensitivity analysis.


A novel efficient method for the synthesis of 3'-β-branched uridines starting from uridine was developed, in which a SmI2-promoted intramolecular Reformatsky-type reaction was effectively used. 5'-O-(Bromoacetyl)-3'-ketouridine derivatives 12, 26, and 27 were synthesized from uridine and were subjected to an intramolecular Reformatsky-type reaction. When 12, 26, and 27 were treated with 2.0 equiv of SmI2 in THF at −78 °C, intramolecular carbon−carbon bond formation at the 3'-β-position proceeded smoothly to give the corresponding 3',5'-lactones 14, 28, and 29 in high yields, respectively. Treatment of 28 with NH3/MeOH gave the 3'-β-branched uridine derivative 32 quantitatively, which was then deprotected to give 3'-C-(carbamoylmethyl)uridine (33).


Palatal bone biopsies from nine children 22 to 24 months of age, with complete unilateral cleft, showed that palato-vomer plasty results in uninterrupted osseous closure of the cleft in the hard palate. The newly formed bone had fused with the nasal septum, but no suture had developed corresponding to the fusion. The bone contributed to the vertical growth of the nasal and oral cavities, but in spite of an extremely active suture on the non-cleft side the osseous closure of the cleft seems to inhibit transverse maxillary growth. Periosteal biopsies from the same children obtained from the buccal aspect of the maxilla from the region of the second deciduous molar on both sides, showed reduced appositional growth activity on the cleft side. Periosteal biopsies from nine unoperated children aged 2 months with the same type of cleft showed equal appositional growth activity on both sides. It is recommended to avoid any surgical procedure resulting in osseous closure of the cleft in the hard palate until the s...


In computational materials research, uncertainty analysis (more specifically, uncertainty propagation, UP) in the outcomes of model predictions is essential in order to establish confidence in the models as well as to validate them against the ground truth (experiments or higher fidelity simulations). Unfortunately, conventional UP models relying on exhaustive sampling from the distributions of input parameters may be impractical, particularly when the models are computationally expensive. In these cases, investigators must sacrifice accuracy in the propagated uncertainty by down-sampling the input distribution. Recently, a method was developed to correct for these inaccuracies by re-weighing the input distributions to create more statistically representative samples. In this work, the method is applied to computational models for the response of materials under high strain rates. The method is shown to effectively approximate converged output distributions at a lower cost than using conventional sampling approaches.

3D line skeletons are simplistic representations of a shape's topology which are used for a wide variety of geometry-processing tasks, including shape recognition, retrieval, and reconstruction. Numerous methods have been proposed to generate a skeleton from a given 3D shape. While mesh-based methods can exploit existing knowledge about the shape's topology and orientation, point-based techniques often resort to precomputed per- point normals to ensure robustness. In contrast, previously proposed techniques for unprocessed point clouds either exhibit inferior robustness or require expensive operations, which in turn increases computation time. In this paper, we present a new and highly efficient skeletonization approach for raw point cloud data, which produces overall competitive results compared to previous work, while exhibiting much lower computation times. Our algo- rithm performs robustly in the face of noisy and fragmented inputs, as they are usually obtained from real-world 3D scans. We achieve this by first transferring the input point cloud into a Gaussian mixture model (GMM), obtaining a more compact representation of the surface. Our method then iteratively projects a small subset of the points into local L1-medians, yielding a rough outline of the shape's skeleton. Finally, we present a new branch detection technique to obtain a coherent line skeleton from those projected points. We demonstrate the capabilities of our proposed method by extracting the line skeletons of a diverse selection of input shapes and evaluating their visual appearance as well as the efficiency compared to alternative state-of-the-art methods.


In this case, the Court of Justice of the EU (CJEU) was asked to consider whether provisions of the Greek Civil Service Code and the Code of the Status of Judges that restricts access to parental leave for fathers in circumstances where the mother of the child was working or was incapacitated by illness or serious injury, were precluded by EU law relating to parental leave, specifically Directives 96/34/EC1 and 2006/54/EC.

The variation of linear correlation factor of dielectric polarization (g) with the concentration and the dielectric virial coefficients for acetic acid in two nonpolar solvents namely n-heptane and p-xylene were investigated. For the two systems investigated a low value for g and large negative values for were obtained which are consistent with the well established long living dimers formed by these molecules. From the first virial coefficient the 'apparent solution moment' of acetic acid at infinite dilution in the two systems was estimated. Introduction One of the import and intersting phenomena in liquid state investigations is the dipole association of liquids when they are dissolved in different solvents. For such type of studies even though there are other techniques like IR and NMR studies, they do not provide so direct a picture regarding neighbouring association as is possible by dielectric studies. The present paper deals with the investigations on the linear correlation factor of dielectric polarization (g) and second dielectric virial coefficient (38) of acetic acid in two non-polar solvents namely n-heptane and p-xylene, as such studies provide valuable information regarding short range inter-molecular interactions, and hence information regarding dipole association in fluids. A correlation of these two may help to a considerable extent in understanding the association in liquids. The first virial coefficient helps one to estimate the "apparent solution moment" at infinite dilution. The basis for the experimental determination of g for various concentrations of the polar solutes is the Kirkwood-Frohlich relation extended to solutions [1] where 0 represents the molar volume of the solution, e the dielectric constant of the solution, x, the mole fraction of the pure solvent, x2 the mole fraction of the solute, Theory


Novel scientific research can be introduced in the experimental teaching of mechanics. The benefits will not only promote the teaching level by the applications of scientific researches, but also widen students' view fields of knowledge and stimulate their learning interests. The measurement of two-dimensional digital image correlation is easily applied and its operation is also simple, and thus it is suitable to be explored and applied in the teaching of mechanical experiments for undergraduate students. Taking the beam bending experiment for an example, the two-dimensional digital image correlation can be utilized to obtain the strain distribution on the cross-section of beam and the elastic modulus of specimen. The linear distribution of normal strain along the cross-section of the bending beam is clearly demonstrated by the contour fringes of the normal strain. Also, the measured elastic modulus of the specimen is simular to the theoretical magnitude of the material. The results manifest the method is practical and effective in the teaching of mechanical experiments.
