Ci experienced 2 communication phases in regard to the usage of communication media: "singers' Ci" period(from Tang Dynasty to North Song Dynasty) and "scholars' Ci" period(from South Song Dynasty to early Yuan Dynasty).During the first period,Ci propagation mainly depended on singers' songs.To be songs of singers was the main objective of Ci,and Ci was in the phase of oral media.During the second period,Ci propagation mainly depended on paper media such as letters,presswork,etc.The most important feature of Scholars' Ci is that the creation of scholars no longer needed to consider the taste and literary training of singers,therefore,the authors tended to express their personal life experience,emotion and to exchange their works.Ci gradually became a delicate literature product and developed its own classical style.

For much of the last century, scholars have debated whether, and to what extent, law constrains judicial decisions. Rule skeptics—including many legal realists, critical legal scholars, and political scientists—have argued that legal rules are seldom determinate and that judges have substantial discretion to decide cases according to extralegal criteria. Legal positivists such as Hart (1961), on the other hand, agree that legal rules are occasionally indeterminate, but assert that the law is clear and binding in most cases. A third position, taken by interpretivists such as Dworkin (1986) and many proponents of natural law, is that law is always determinate, although it does not always constrain judicial decisions in practice.

This paper presents a 48V conversion chain typical of a mild hybrid electric vehicle with enhanced strip-layout trench-gate MOSFETs applications. The MOSFETs technology allows modulating the inner device parameters to improve the device impact on the converter application. Several converter topologies used in the 48V bus are considered to explore how the switching transients and thermal issue are linked to power device performance. The correct choice of the MOSFET switch leads to improve the converter design and the reliability of the whole low voltage hybrid electric vehicle application.

Cardiomyocytes derived from human induced pluripotent stem cells (hiPSC-CM) may provide an important bridge between animal models and intact human myocardium. Fulfilling this potential is hampered by their relative immaturity. hiPSC-CMs grown in monolayer culture lack a t-tubular system, have rudimentary intracellular calcium-handling systems, express predominantly embryonic sarcomeric protein isoforms, and preferentially use glucose as energy substrate. Culturing hiPSC-CM in a 3D environment and the addition of nutritional, pharmacologic and electromechanical stimuli have proven to be beneficial for maturation. We present an assessment of a model in which hiPSC-CMs and hiPSC-derived cardiac fibroblasts are co-cultured in a 3D fibrin matrix to form human engineered cardiac tissue constructs (hECT).The hECT respond to physiological stimuli, including stretch, frequency and β-adrenergic stimulation, develop a t-tubular system, and demonstrate calcium-handling and contractile kinetics that compare favorably with ventricular human myocardium. Transcript levels of genes involved in calcium-handling and contraction are increased. These markers of maturation become more robust over a short period of time in culture (6 weeks vs. 2 weeks in hECT). A comparison of the hECT molecular and performance variables with those of human cardiac tissue and other available engineered tissue platforms is provided to highlight strengths and weaknesses of these preparations. Important and noteworthy aspects of this human cardiac model system are its reliance on 'off-the-shelf' equipment, ability to provide detailed physiological performance data, and the ability to achieve a relatively mature cardiac physiology without additional nutritional, pharmacological and electromechanical stimuli that may elicit unintended effects on function.


 Abstract —YouTube is the world's most popular video platform, which not only provides entertainment videos, but also allows many professional or amateur teachers to upload teaching videos for users to learn specific skills. However, most of the current research focuses on the effectiveness of YouTube for formal learning. In the perspective of cognitive-affective theory of learning with media (CATLM), the informal learning model through YouTube can also be regarded as a meaningful learning method. Therefore, based on CATLM, this research constructed a research model and proposed 4 research hypotheses. For the purpose of the research, this research used Facebook's hand-made leather goods club to distribute questionnaires, collected 258 questionnaires, and deleted a total of 51 copies of questionnaires with invalid data. Then the number of questionnaires with valid data were 207, and the effective recovery rate was 80.2%. The data were analyzed for reliability and validity, and SEM was used to verify the research model. The research results showed that: 1) YouTube self-efficacy was positively related to learning interest; 2) YouTube self-efficacy was positively related to learning attitude; 3) Learning attitude was positively related to h learning satisfaction; 4) Learning interest was positively related to learning


ABSTRACT Teaching the concept of inferential statistics is one of the most challenging tasks for statistics educators. Often, students cannot make logical connections between inferential statistics and other topics such as descriptive statistics and probability. The source of difficulty may be that inferential statistics is based on complex ideas such as hypothetical reasoning, data analytic methods, and probabilistic thinking. This article presents classroom practices that teachers can easily adapt for their statistics classes to teach fundamental ideas of inferential statistics. The expected educational outcome is the conceptual understanding of the elements of statistical testing rather than learning about a specific testing methodology. Using the proposed practices, students are guided to propose their own hypotheses, collect actual data, and make their own inferences, rather than following a predetermined sequence of procedures. The practice material is divided into three subtasks, so that teachers can plan their curriculum effectively and perform formative assessments regarding students' progress.


Neutron energy spectra were measured at 0 degrees from 83.7-MeV deuteron bombardment of a 2.0-cm-thick beryllium target and 100.2-MeV proton bombardment of a 60-MeV-thick beryllium target backed with aluminum.


A novel series of 2-((4-(4,6-dimethoxypyrimidin-2-yl) phenyl) amino) thiazol-4(5H)-one derivatives(9a-j) have been synthesized VIA Suzuki-Miyaura cross-coupling. The structures of all the newly synthesized analogues were characterized by IR, H NMR, C NMR and mass spectroscopy. All synthesized derivatives were examined for their in vitro antibacterial activity against gram-positive & gram-negative bacteria as well as antifungal activity against different strains by using broth dilution technique. The consequences of antimicrobial study exposed that some of the newly synthesized compounds exhibit potent activity against the examined microbial strains.


Optical and ultraviolet observations are presented of the 1979 outburst of the recurrent nova U Sco. For the first time the evolution through outburst is documented photometrically and spectroscopically. Lines of the following ions are identified: H I, He II, C IV, N III, N IV, N V, O IV, O VI and Si IV. No forbidden lines were observed. Mg I was seen in absorption at a late stage in the decline. The Balmer lines have broad and narrow components which change with time. There is evidence that nitrogen is overabundant with respect to carbon and the helium to hydrogen number ratio is about 2.


Deep Reinforcement Learning (Deep RL) agents have in recent years emerged as successful models of animal behavior in a variety of complex learning tasks, as exemplified by Song et al. [2017]. As agents are typically trained to mimic an animal subject, the emphasis in past studies on behavior as a means of evaluating the fitness of models to experimental data is only natural. But the true power of Deep RL agents lies in their ability to learn neural computations and codes that generate a particular behavior—factors that are also of great relevance and interest to computational neuroscience. On that basis, we believe that model evaluation should include an examination of neural representations and validation against neural recordings from animal subjects. In this paper, we introduce a procedure to test hypotheses about the relationship between internal representations of Deep RL agents and those in animal neural recordings. Taking a sequential learning task as a running example, we apply our method and show that the geometry of representations learnt by artificial agents is similar to that of the biological subjects', and that such similarities are driven by shared information in some latent space. Our method is applicable to any Deep RL agent that learns a Markov Decision Process, and as such enables researchers to assess the suitability of more advanced Deep Learning modules, or map hierarchies of representations to different parts of a circuit in the brain, and help shed light on their function. To demonstrate that point, we conduct an ablation study to deduce that, in the sequential task under consideration, temporal information plays a key role in molding a correct representation of the task.


Most of divorce cases in Indonesia have a negative impact on divorced children and wives. This is due to the lack of public legal knowledge especially wives who are entangled in divorce cases so that their rights are often ignored. Judges of the Religious Court, in this regard, have a very important role in the protection of the rights of children and wives through the instrumentation of ex-officio rights which, because of his position, he has special authority in deciding the divorce case. This research is a combination of normative and empirical juridical research by connecting the case approach and the legislative approach. The research was conducted at the Bekasi Religious Court using the interview, observation and literature study methods. This study aims to analyze the conception of the rights of ex-officio judges, the basis for their consideration and the mechanism of their instruments in issuing decisions on divorce cases and their relevance to Islamic law


In the increasingly serious contradiction between the water resource supply and demand in China, especially in North China, several key factors of floodwater utilization such as necessity and feasibility, theory and technology of reservoir optimization dispatching and risk rate calculation are analyzed. Finally, under the current situation of China's water short, some concrete measures and suggestions on floodwater utilization in the future are proposed.


To shed more light on the relationship between ischemic heart disease and iron, serum iron parameters (iron, ferritin and transferrin) were estimated in fifty ischemic heart patients (15 stable angina, 15 crescendo an gina and 20 acute Myocardiai Infarction, MI). Their ages ranged 43 – 58 years. Ten healthy subjects, matched with patients for age and sex. served as control group. Echocardiographic studies (ejection fraction (EF) and end systolic volume (ESV) together with peak serum creatine phosphokinase (CPK) were done for each case of infarction to correlate these variables with the corresponding serum iron parameters. Compared to controls, ischemic heart patients had highly signi/icon: increase of serum iron (103.5 ± 25.6 vs 79.6 ± 19.2, p<0.0l) and serum ferritin (94.7 ± 54.2 vs 44.4 ± 11.0, p<0.01) whereas they showed insignificant increase of serum transferrin (273.8 ± 83.8 vs 244.1 ± 56.4, p>0.05). Subgroup analysis showed that there was statistically signif icant increase in serum iron and ferritin but not transferrin in patients with stable and unstable angina while in cases with acute MI, there was significant increase in oil serum iron parameters. Correlation studies showed that serum iron and ferritin but not transferrin were strongly correlated with peak CPK, EF and ESV. Patients with acute MI who had complicated in-hospital course showed significant higher value of serum iron, ferritin, transferrin, CPK and ESV but they had a significant lower EF than non-complicated cases.


Background: The low activation threshold of T-type CaV3.2 channels is central to neuronal rhythmogenesis. Results: The S4-S5 linker of Domain II is functionally coupled with Domains II and III during channel activation. Conclusion: Activation of CaV3.2 requires a specific interaction between adjacent domains. Significance: Disrupting this protein interface could be a pharmacological strategy to decrease Ca2+ influx in neuronal pathologies. T-type CaV3 channels are important mediators of Ca2+ entry near the resting membrane potential. Little is known about the molecular mechanisms responsible for channel activation. Homology models based upon the high-resolution structure of bacterial NaV channels predict interaction between the S4-S5 helix of Domain II (IIS4-S5) and the distal S6 pore region of Domain II (IIS6) and Domain III (IIIS6). Functional intra- and inter-domain interactions were investigated with a double mutant cycle analysis. Activation gating and channel kinetics were measured for 47 single mutants and 20 pairs of mutants. Significant coupling energies (ΔΔGinteract ≥ 1.5 kcal mol−1) were measured for 4 specific pairs of mutants introduced between IIS4-S5 and IIS6 and between IIS4-S5 and IIIS6. In agreement with the computer based models, Thr-911 in IIS4-S5 was functionally coupled with Ile-1013 in IIS6 during channel activation. The interaction energy was, however, found to be stronger between Val-907 in IIS4-S5 and Ile-1013 in IIS6. In addition Val-907 was significantly coupled with Asn-1548 in IIIS6 but not with Asn-1853 in IVS6. Altogether, our results demonstrate that the S4-S5 and S6 helices from adjacent domains are energetically coupled during the activation of a low voltage-gated T-type CaV3 channel.


Application of fractals in the analysis of microseismicity associated with rockbursts in underground mines has gained increased importance in recent years, and provided a new direction to the study of mining induced seismicity. The approach is based on the selection of appropriate fractal techniques which include the multifractal approach and applying them to the qualifying data. The spatial and temporal distribution of microseismie events leading to the determination of correlation dimension. D. and the seismic b-value from which the powerlaw exponent, D is calculated, have proved to be the most useful among various parameters. Fractal concepts and measurement methods are presented along with the results and discussion of a few case studies including those of Champion Reef Mine. KGF. The overall results show that the application of fractals can improve the utility of microseismic technology towards combating the problems of rockbursts and also for investigating the mine respouse to stress changes.

Concrete structure needs an inspection to prevent structural failures. In concrete inspection activity, ground-penetrating radar (GPR) is one of the tools used to detect the location of steel reinforcement in concrete without the need for invasive action. In this paper, GPR for concrete inspection application is designed using frequency modulated continuous wave (FMCW) and works on ISM bands with a frequency range of 2.4 – 2.5 GHz. Based on radar cross section value and total loss value, a calculation is performed using the radar equation to find the total gain required by the system. The total gain value required by the GPR system with 1-meter detection capability is 11.066 dB and the total gain requirement can be fulfilled using an antenna and low noise amplifier. Meanwhile, the total gain value required by the GPR system with 3-meter detection capability is 165.79 dB. In this research the RX and TX antenna beamwidth specification was calculated. The RX antenna is expected to meet 2.86° – 48.45° beamwidth specifications for 1-meter detection capability and 0.95° – 17.6° beamwidth specifications for 3-meter detection capability. The TX antenna is expected to meet 90° – 126.87° beamwidth specifications for 1-meter and 3-meter GPR detection capability. The GPR FMCW system designed in this paper uses Lime SDR as a transceiver module.


The medical colleges in our province are weak in overall creativity and sustained creativity. It is advisable for medical colleges to make full use of the available man and information resources, establish multiple personnel-sharing and personnel-cultivating modes in which the professional personnel is shared, colleges are integrated, research projects are jointly carried out, the colleges and enterprises are cooperated with each other, and the academic knowledge is intercommunicated, thus giving play to the superior effect for the cultivation of creative innovators. Emphasis should be laid on changing education concepts and teaching modes, making best use of the role of the leading personnel of each subject, and further strengthening effective competition and excitement mechanism and institution guarantee.


We present a serendipitous detection of the infrared-bright supernova remnant (SNR) B0104-72.3 in the Small Magellanic Cloud by the Infrared Camera (IRC) onboard AKARI. An elongated, partially complete shell is detected in all four observed IRC bands covering 2.6-15 um. The infrared shell surrounds radio, optical, and X-ray emission associated with the SNR and is probably a radiative SNR shell. This is the first detection of a SNR shell in this near/mid-infrared waveband in the Small Magellanic Cloud. The IRC color indicates that the infrared emission might be from shocked H2 molecules with some possible contributions from ionic lines. We conclude that B0104-72.3 is a middle-aged SNR interacting with molecular clouds, similar to the Galactic SNR IC 443. Our results highlight the potential of AKARI IRC observations in studying SNRs, especially for diagnosing SNR shocks.


Editor's Summary To engineers involved in designing, developing, or operating control systems for practical applications, research in control may seem an exercise in mathematical abstractions. As an engineering discipline, however, the connection with the physical world is intrinsic to control. Interfacing with sensors and actuators, implementing advanced algorithms on real-time platforms, dealing with sampling time issues, and other such pragmatic matters may seem to be taken for granted in much of advanced control, but in fact there is an extensive body of research that is concerned with these very topics All advanced control algorithms today are hosted on digital computing systems, and any discussion of real-time control applications must address the specific issues and challenges associated with digital implementation. The benefits of digital realization are numerous: software-based computing allows more sophisticated control laws; updates and maintenance are rendered easier in many cases; control systems can be made more compact; and control can more readily be integrated with ancillary functions such as information display, system health management, and data recording. But the digital world brings complications too. For example, the continuous variables of a physical system must now be discretely sampled. Variations in the sampling rate are generally assumed to be negligible, but this is not always the case and a significant adverse impact on control quality can result. Similarly, variable delays arise in the processing of sensory data. In today's processors, even the same sequence of arithmetic operations can take more or less time to execute depending on the state of the processor and operand values. As control programs become more complex, so do their real-time implementations. Most control system computing platforms are used for several tasks in addition to executing the base control law. Realtime computing and control thus also involves the solution of difficult scheduling problems. Different tasks can have different priorities, desired execution frequencies, and execution times; there may be dependences between them that require interprocess communication and accessing of shared resources; and failures of sensors and actuators and other abnormal situations cannot be allowed to compromise safety.


We present timing and broad band spectral studies of the high-mass X-ray binary pulsar 4U 1909+07 using data from Suzaku observations during 2010 November 2–3. The pulse period of the pulsar is estimated to be 604.11 ± 0.14 s. Pulsations are seen in the X-ray light curve up to ∼70 keV. The pulse profile is found to be strongly energy-dependent: a complex, multi-peaked structure at low energy becomes a simple single peak at higher energy. We found that the 1–70 keV pulse-averaged continuum can be fit by the sum of a blackbody and a partial covering Negative and Positive power law with Exponential cutoff model. A weak iron fluorescence emission line at 6.4 keV was detected in the spectrum. An absorption-like feature at ∼44 keV was clearly seen in the residuals of the spectral fitting, independent of the continuum model adopted. To check the possible presence of a cyclotron resonance scattering feature (CRSF) in the spectrum, we normalized the pulsar spectrum with the spectrum of the Crab Nebula. The resulting Crab ratio also showed a clear dip centered at ∼44 keV. We performed statistical tests on the residuals of the spectral fitting and also on the Crab spectral ratio to determine the significance of the absorption-like feature and identified it as a CRSF of the pulsar. We estimated the corresponding surface magnetic field of the pulsar to be 3.8 × 1012 G.


One of the most used approaches to synchronize power electronic converters to electrical power systems is the phase-locked loop (PLL). PLLs with adaptive characteristics such as the PLL based on a double second order generalized integrator (DSOGI - PLL) are widely used in the synchronization of three-phase power converters, due to their adaptive filtering characteristics and the improvement that is obtained by adding a sequence component calculator before the loop filter. However, the accuracy of the PLL measurements, and therefore the calculation of the phase angle, is affected during transients, so that the frequency, phase angle, and voltage calculated by the PLL are a function of the disturbance type and the architecture of the PLL. This article proposes an improved DSOGI-PLL with a frequency -lock loop based on a double generalized second order integrator (DSOGI-FLL) which is more stable and shows a faster response than the conventional DSOGI-PLL. The main idea is to combine the strengths of these two algorithms into one architecture that will be called DSOGI-PLL with FLL. The performance of the proposed PLL is verified and validated under the processor in the loop (PIL) approach.

"Pulmonary clinicians often are faced with manage-*-ment problems for which there are no answers at hand, either because there is no literature which def¬ initely gives answers or because the circumstances surrounding the clinical cases are unusual enough to prevent the application of existing scientific knowl¬ edge. When faced with these problems, clinicians are forced to make decisions based on a logical extension of their scientific knowledge into uncharted clinical waters. They are forced to make judgments based on the conviction of their speculations and the prior experiences of others and of themselves.


In a distributed network of computing hosts, the performance of the system can depend crucially on dividing up work effectively across the participating nodes. Dynamic load balancing have the potential of performing better than static strategies, they are inevitably more complex. The overheads involved are much more. But one can not negate their benefits. Load balancing is found to reduce significantly the mean and standard deviation of job response times, especially under heavy and/or unbalanced workload. The performance is strongly dependent upon the load index; queue-length-based indices perform better. The reduction of the mean response time increases with the number of hosts, but levels off beyond a few tens of hosts. Load balancing is still very effective when a large portion of the workload is immobile. All hosts, even those with light loads, benefit from load balancing. Similarly, all types of jobs see improvements in their response times, with larger jobs benefiting more. System instability is possible, but can be easily avoided. The random arrival of tasks at each processor is likely to bring about uneven processor loads in a distributed system. Various approaches are there to provide the dynamic load balancing. In one scheme, Load balancing can be improved by having one centralized node to handle the uneven load. The project work shows that efficiency can be improved by replacing the centralized node with a number of nodes added with interrupt service. The scheme can reduce the waiting time by significant amount of time.


In the mid-1980s India began broadcasting a pro-development soap opera Hum Log which achieved tremendous success with both its audiences and advertisers. Moreover Indias successful experience with this program has convinced national leaders in other Third World countries to launch similar programs. Pro-development soap operas are unique in that they seek to break down the artificial distinction between education and entertainment-oriented programming. Essential components of such programs are to: attract a large audience emphasize cultural archetypes represent emotions promote socially desirable values and provide a vehicle for social learning. A content analysis of the Hum Log series indicated it addressed many of the important social issues confronting Indian society: family harmony womens status moral development national integration family planning health urbanization and national welfare programs. About 50 million people watched the average Hum Log episode which at the time (1984-85) was the largest television audience for any program. A survey of 1170 viewers indicated that 94% considered the program entertaining 91% felt it addressed important social problems and 83% found it educational. Although the initial episodes focused on family planning pressures from audiences sponsors and the Indian Parliament forced producers to dilute the family planning theme and emphasize closely related themes such as womens status family harmony and family welfare. This shows that the educational content of soap operas cannot be too blatant or hard-sell. During the 17 months its broadcast Hum Log received letters from 400000 viewers most of which confirmed the pro-social impact of the program. Hum Logs commercial success further led to a proliferation of domestically produced television serials and a decreased reliance on imported programming.

Water shortage problem is increasingly becoming the focus of great concern to everyone in the world. First, we develop two models—Macroscopic Model and Microscopic Model to measure the ability of a region to provide clean water. We calculate the amount of water supply and demand approximately, and we adopt a Macro-Model to measure the water provision ability in a large region. While the Micro-Model concentrates on the dynamic nature of the factors. Then we use the unified criteria and determine the weighs via the AHP, working out an indicator to reflect the ability to provide clean water in a certain region. Second, we pick Beijing for further study. We conclude that the water is heavily overloaded in Beijing, mainly caused by the large population. Finally, our intervention plan is to build a new dam in Beijing. Applying the goal programming, we determine the specific way to build this dam. Our primary goal is to mitigate water scarcity in Beijing, namely improve water availability. Meanwhile, our minor aim is to minimize the investment of this dam projection. Additionally, we analyze the influence on the surrounding areas and the entire water ecosystem. Introduction As we all know, water is indispensable to our life and the development of national economy. It is often described as the source of all living things and the lifeblood of agriculture and industry. Without it, nothing could grow and world would become a terrible desert. With the development of modern industry and the growth of population, water shortage has become a growing concern for government and people all over the world. Several factors contribute to this issue. On the one hand, water supplies are being consumed by a growing number of heavy industries as well as the increasing population. On the other hand, plenty of rivers and lakes have been polluted. What's more, climate change has made the situations worse. Last but not the least, poor management and lack of infrastructure also limit the availability of clean water. It is high time for us to do something to prevent it from being worse. In order to solve the problem, several measures can be taken. First, we must economize the use of water resources and practice a recycling policy. Second, stricter laws and regulations should be implemented to protect the limited water resources we have. Finally, more diversion projects should also be used so as to direct the surplus water resources in the Southern Chine to the under-supplied regions. In a word, stronger measures can and should be taken to protect the water resources we have now. General Model for Water Supply and Demand We develop two models to tackle the problem. The Macro-Model is designed to measure the ability of a region to provide clean water to meet the needs of its population, while the Micro-Model concentrates on the dynamic nature of the factors that affect both supply and demand, based on more detailed information about the region we research, such as GDP, population, rainfall etc. The outcomes of those two approaches show great consistency when applied to a real scenario. Macro-Model. Usually, we do not know some details in a large area, we can only calculate the amount of water supply and demand approximately, so we adopt a Macro-Model. 873 7th International Conference on Education, Management, Computer and Society (EMCS 2017) Advances in Computer Science Research (ACSR), volume 61


ABSTRACT

Background: Perioral modifications are significant stigmata of systemic sclerosis, with functional implications that negatively impact daily life. Lips stiffening results in microstomia, dryness, easy ulceration, difficult speech, food biting, oral hygiene and dental care, besides alteration in psychosocial interactions.

Objective: As fat grafting has emerged as a "regenerating" treatment for scarred and fibrotic tissues, scleroderma patients may receive significant benefits from the procedure.

Methods: fat grafting was proposed to patients with perioral fibrosis in systemically stable scleroderma. 8 patients in 2 years met inclusion criteria and accepted grafting. Patients were stadiated for functional impairments with a specifically designed questionnaire. Follow up for up to 12 months included a post-operative questionnaire for subjective functional performance of the perioral region (-5/+5 scale), serial echographic assesments of fat grafts, and lips width measurement.

Results: patients reported pre-operative impairment concentrated in three daily activities (speech, eating, oral hygiene) and three psychosocial items (uneasiness with others, tension in interactions, embarrassment in interactions). After fat grafting, all patients reported significant benefit in lips softness, mouth opening and appearance at 1 and 3 months. One patient reported total regression of achieved benefits by the third month. All other patients reported a partial regression of functional benefits between the 3 and 6 months, with results then stable at 1 year, with subjective perception of improvements >+3 (in -5/+5 scale) in lips sensibility, lips/mouth dryness, movement, opening, softness, as well as aesthetics and easiness in social interactions. Serial echography confirmed a significant increase in thickness in grafted areas, with progressive reabsorption over time. No variations in lips diameters were detected.

Conclusions: fat grafting seems an option to provide functional relief to systemic sclerosis patients with perioral impairment. Even if not all patients may respond, most seem to receive long term functional benefits.

This research project will explain the participatory work I am doing with the Eli and Edythe Broad Art Museum at Michigan State University. The museum desires to enhance visitor participation. With little information on their visitors, however, designing these participatory elements is difficult. To help solve this problem, I have designed a project aimed at mapping visitor's experiences to better understand how the museum could encourage different kinds of participation. Researching visitors' experiences could provide an appropriate time and place for collecting information, thus eliminating visitor anonymity.


Lower extremity exoskeleton is a mechanical device mainly for augmenting the performance of a healthy person or assisting the people with lower limb pathology. In this study technology evolution of lower extremity exoskeletons was analyzed from the patent perspective. Patent citation analysis based on a specific patent issued by USPTO in 2011 was carried out to trace the evolution of technology concepts in the past four decades. The technologies of control system, sensor, actuator and mechanism applied were compared from the viewpoint of hip, knee and ankle movement, and the most or relatively more cited patents were selected as the representatives of technology. Several trends of design concept with respect to the hip, knee and ankle movement were presented in the paper. For example, for the design of subsystem hip joint, the considerations were taken gradually from prevention of subluxation or dislocation of hip joint alone at the early days to reducing metabolic energy associated with walking/running as well as reducing the incidence of falls caused by the insufficient leg thrust recently. For the design of subsystem knee joint, articulated splints with hinge pivot, articulate notch or spring at the beginning were replaced by the piston and cylinder assemblies with adjustable valves to resist the flexion and extension of the joint, and later by the damping member with control unit for detecting the force, knee angle and acceleration.


A general procedure of solving incompressible viscous flow around multiple moving bodies was developed. An overlapped unsteady grid system which consists of a stationary main grid and subgrids attached to each moving body was employed. The incompressible N-S equations were calculated over this grid system. As a numerical scheme, the convective terms were approximated by the generalized QUICK method. A semi-implicit second-order two-step method was devised for unsteady time integration. The pressure was accurately solved by the newly developed Neumann Poisson solver. To make the procedure global, a mask function was introduced instead of dividing the main grid into several subregions. Triangular interpolation was applied for data communication between each grid. The accuracy of the procedure was verified by examining the flow around an oscillating cylinder. An application to flows around several moving bodies with multiple overlapped regions was made, which ensured the versatility of the present procedure.


In this work, the Ce/Tb/Sm doped glasses with the composition of TeO2-B2O3-ZnO-Na2O were synthesized by melt quenching process. The photoluminescence properties of glasses doped with Ce3+, Tb3+ and Sm3+ single, doubly and triply doped TeO2-B2O3-ZnO-Na2O (TBZN) were studied by mean of emission and excitation spectra. There was an overlap between Ce3+ emission and Tb3+, Sm3+ absorption in the wavelength range of 350500 nm. Therefore, it was expected that an efficient energy transfer occurred from Ce3+ to Tb3+ and Ce3+ to Sm3+ ions. When excited by ultraviolet wavelengths the co-doped glasses emit a combination of blue, green and red orange forming white light. [doi:10.2320/matertrans.MA201509]


The impedances were defined as the pilot impedances aiming at the generality that is extracted from the pilot protection principles of the transmission lines based on the impedances obtained by the line two-terminals electrical quantities on the published papers.The impedances are respectively named as the pilot impedances of Quotient Summation,Summation Quotient,Difference Quotient and Enhanced Difference Quotient according to their calculating forms and numerical results of each pilot impedance.The unified physical circuit model was determined for the pilot impedances.The physical circuit model not only improved the reasonable physical definition and the exact mathematic expression based on the single-phase and three-phase equivalent line models,but also strengthened the inter-phase decoupling algorithms and the capacitance compensating methods based on the accurate mathematical-physical deduction.The state characteristics of whole pilot impedances were cleared and the performance index of part pilot impedances was improved.A 1 000 kV 500 km simulating line model was established on electro-magnetic transient program(EMTP),and a 750 kV laboratory line model from Lan Zhou Dong to Xian Yang constructed by China Electric Power Research Institute was used.Simulation results showed the validity of the above research work.


Our atmosphere is full of electromagnetic fields emitted from wireless communication transmitters. At the same time the bio-systems (including humans, animals & birds and vegetation as well) are complex electrical systems. Naturally therefore, they are likely to have interaction and to be affected in some way or the other. Research into this field started with the knowledge about pleasing presence of negative charges and unpleasant presence of positive charges around us, concentrating effects of static or pulsating fields. Also came the explanation (and experimental verification) of Hindu mythological effects of geomagnetic fields coupled with solar activity. The effects of power line radiation and radiation from video game TV sets, microwave oven and other domestic instruments like electric blankets also figured in the research. At last the fastest emerging mobile telephony overpowered all others. Though the results of researches into possible harmful effects of mobile phone radiation and those of radiation from base station towers remain inconclusive partly because of influencing pressure from manufacturing and service providing companies, some of the researchers conclusively assert the harmfulness of the radiation at some level of field intensity present near the tower or the handset relating it to the specific absorption ratio (SAR) value. Recent increased observation of infertility among young couples is also attributed by some researchers to the effect of radiation from mobile kept in pantaloons pockets which becomes near their genitals affecting sperm or ovum. This review explains all these researches into bio-effects of electromagnetic fields and concludes that there is certainly some possible harmfulness of radiation above some level of intensity of fields.


Introduction:
 Ventricular dysfunction contributes to shock in cardiac intensive care unit (CICU) patients. We aimed to describe the associations between ventricular dysfunction with in-hospital mortality across the spectrum of shock severity.

 Hypothesis:
 Patients with biventricular dysfunction (BVD) have higher mortality at each Society for Cardiovascular Angiography and Intervention (SCAI) shock stage.

 Methods:
 We identified CICU patients from 2007 to 2015 with available echocardiography data within 1 day of admission. Left ventricular systolic dysfunction (LVSD) was defined as left ventricular ejection fraction <40% and right ventricular systolic dysfunction (RVSD) as moderate or greater systolic dysfunction by semi-quantitative assessment; BVD included the presence of both LVSD and RVSD. Predictors of in-hospital mortality were determined after adjustment using multivariable logistic regression.

 Results:
 We included 3,158 patients with a mean age of 68.2±14.6 years; 51.8% had acute coronary syndromes. LVSD was present in 22.3%, RVSD in 11.8%, and 16.4% had BVD. Hospital mortality increased with SCAI shock stage and was incrementally higher in patients with LVSD, RVSD and BVD across SCAI shock stages (Figure); patients with BVD had higher mortality in each SCAI shock stage. After adjustment, there was no difference in in-hospital mortality for patients with LVSD or RVSD versus those without ventricular dysfunction (p >0.05), but BVD was independently associated with higher in-hospital mortality (adjusted HR 1.815, 95% CI 1.237-2.663, p = 0.0023). Adding ventricular dysfunction to SCAI shock stage increased discrimination for hospital mortality (AUC 0.784 vs. 0.766, p <0.001).

 Conclusions:
 Among patients admitted to the CICU, BVD was independently associated with higher hospital mortality after adjustment for shock severity. Echocardiographic assessment may augment clinical risk stratification using the SCAI shock classification.


In this d isserta tion , we m easure the cross section for the elastic scattering of electron neutrinos on electrons. We use d a ta from the LSND experim ent which is located a t the Los Alamos Neutron S cattering Center at Los Alamos N ational Laboratory, New Mexico. The neutrino beam is produced when an 800 MeV proton beam from a linear accelerator is incident on a target lo cated 29.8 m from the detector. The LSND veto system allows us to reject charged cosm ic-ray particles entering the detector w ith high efficiency. The detector consists of 180 tons of mineral oil. to which a small quantity of scintilla tor is added. This com bination enables us to detect both Cerenkov and scintillation light produced by highly relativ istic charged particles. For the neutrino-electron elastic scattering process, we detec t the recoil electron and require it to be scattered along the direction o f the incident neutrino. This requirem ent has a large acceptance for the elastic scattering events while a t the sam e tim e it reduces the background due to other processes. We obtain 133 ± 22 events for the uee~ —> uee~ process and measure a cross section, cr = [11.6 ± 1.9(sfaf.) ± lA (sys t.)] x fs^ M eV ) x 1045cm 2, for this reaction. The average energy of the ue beam at LSND is 31.7 MeV. A feature of th is reaction is th a t it can proceed through either charged cur rent or neutral current interactions. The s tan d ard model of electroweak interactions predicts a destructive interference betw een these two channels which leads to a reduction in the cross section from its value had there been no interference. We measure the strength of th is destructive interference,


The reliability of power communication network, which is the supporting network of smart grid, has been the prerequisite for economical and safe operation and intelligence of smart gird. As an effective measurement of network reliability, vulnerability can show the performance when a network is attacked or some network units fail. A vulnerability analysis method of power communication network on business layer based on the importance of the power businesses was proposed. To solve the problem of subjective uncertainty caused by experts grading method in traditional importance assessment of power businesses, a new method called feature index method was proposed, in which the scores based on the requirements on the objective indexes replace the ones of experts grading. Take business importance as the parameter of a network, a power communication network model on business layer was established. In the model, the network vulnerability was measured by the loss of business importance when some links had failed. The vulnerability was analyzed in four link failure modes, and the analyzing results showed that the network vulnerability is high under intentional attacks and the more concentrated the distribution of business importance on links is, the higher the vulnerability is. Based on the analysis, a method which can reduce the network vulnerability by changing routing strategy was given and applied to the study case. The simulation results verified the effectiveness of the method.


The first record of Eudociminus mannerheimii (Boheman) in Mexico was reported by Jones et al. (2003) from the municipality of San Juan del Río in the state of Querétaro, based on the collection of one specimen captured from the ground in a riparian forest with Taxodium mucronatum Ten. (Cupressaceae). Jones et al. (2003) suggested T. mucronatum as the probable host for this insect because of the specificity of E. mannerheimii to species of Cupressaceae. On 14 September 2006, a tree inspection was conducted in a riparian area at Ciénega de Mata, Jalisco, Mexico (21°44′38′′N, 101°51′4′′W, 2,086 m elevation) where four T. mucronatum trees were dying. We observed resin flow and sharp, circular insect exit holes (mean diameter 5.4 mm ± 0.5, n = 14) on the bark surface of tree boles from the base up to 10 m above ground level (Fig. 1). Fifteen out of 18 T. mucronatum trees were infested at this site. Insect galleries were observed in the inner bark of infested trees. At the time of inspection, male and female weevils were mating on the bark surface of two large trees (about 1.3 m dbh) and a dead adult was trapped in an exit hole while emerging. Twenty adults were collected by hand in vials filled with 70% alcohol for taxonomic identification. The species was determined as E. mannerheimii (Fig. 2). Twelve specimens are deposited at Campo Experimental Pabellon, INIFAP, Pabellon de Arteaga, Aguascalientes, Mexico and eight specimens at Colegio de Postgraduados, Montecillo, México. This finding confirms T. mucronatum as the host trees for E. mannerheimii in Mexico, as suggested by Jones et al. (2003), and provides a new distribution record. Eudociminus mannerheimii is a forest pest in the southern United States for Cryptomeria D. Don spp., Taxodium ascendens Brongn., and Taxodium distichum (L.) L. C. Rich (all Cupressaceae) (Hopkins 1904; Baker and Bambara 1999; Jones et al. 2003; Mayfield 2004). To our knowledge, this is the first time that E. mannerheimii has been found attacking T. mucronatum in Mexico. The fact that 15 out of 18 adult trees were attacked at the study site suggests this insect could become an important insect pest for old growth T. mucronatum trees in riparian areas. As pointed out by Baker and Bambara (1999) and Mayfield (2004), published literature on this insect is very limited. Research is needed to determine the insect's biology, distribution, and abundance in Mexico. We thank Jorge Valdez for taking the photographs in Fig. 2. We are also grateful to Alfonso Rincón Gallardo, a land owner at Ciénega de Mata, who requested the tree inspection that allowed us to find E. mannerheimii on T. mucronatum.

Females are the dispersing sex in Bell Miners; males tend to be philopatric. The mean age of dispersal (8.0 ± 1.0 months) corresponded closely to the minimum age of first breeding (8.3 months) and may reflect intolerance by females of their sexually mature daughters which may compete for the parental care provided by males. The adult sex ratio was male-biased, probably because of greater dispersal-related mortality suffered by females. Juveniles up to the age of first breeding experienced extremely high mortality (93%). The life expectancy of buds increased dramatically once they reached breeding- age. The number of breeding positions varied little relative to the total number of buds in the social unit. In a social unit of Bell Miners studied over six years there were 6.3 unmated breeding-age buds per breeding vacancy in any month. The level of competitor pressure for breeding positions was more severe for males than females due to the skewed sex-ratio.


Particle image velocimetry(PIV) was used to measure pyrotechnical burning process in order to study flame structure,especially high temperature burning particle movement state,and realize visualization of burning particle movement inside flame.In this paper,some problems such as tracer particle,filter and exposure time were studied and analyzed.And credible experiment data and theory foundation were achieved by testing and discussing experiment image based on MATLAB software.


Background: The collagen type of connective tissue nevus is a hamartoma in which the amount of collagen is increased. It is divided into two groups: the inherited form that contains familial cutaneous collagenoma and shagreen patches in tuberous sclerosis, and the acquired form that contains eruptive collagenoma and isolated collagenoma.Objective: The purpose of this study is to investigate the clinical and histopathological features of the collagen type of connective tissue nevus, along with considering the associated systemic or genetic disorders.Methods: We retrospectively reviewed the medical records and biopsy specimens of 17 patients.Results: We compiled the clinical data and histopathologic feature of 17 patients with the collagen type of connective tissue nevus. The ratio of males to females was 1:1.125 and the mean age of onset was 12.2 years for the patients with eruptive collagenoma and 43.7 years for the patients with isolated collagenoma. Eruptive collagenoma was disseminated on the trunk and arms, but 1 case of eruptive collagenoma was localized on the left thigh. Isolated collagenoma developed as a solitarily lesion on the various sites. The lesions of eruptive collagenoma were less than 1 cm, but the size of the isolated collgenoma varied from 0.5 to 4 cm. Three cases of eruptive collagenoma presented with white-color lesions, but the rest of the eruptive collagenoma and isolated collagenoma showed flesh-colored lesions. No case was combined with congenital or systemic disease. Histopathologically, there were increased thickened collagen bundles that were randomly arranged in the dermis. The elastic fibers were decreased and fragmented.Conclusion: The collagen type of connective tissue nevus is benign and rare, and its clinical and histopathologic characteristics are similar with those of other dermal tumors or reactive disorders. Exact knowledge about the collagen type of connective tissue nevus is needed to differentiate connective tissue nevus from several other disorders that have similar characters and to disclose the association with other diseases.

The article presents the results of investigations, which make a fragment of the broad-scale studies carried out as a part of the statutory activity on optimising the foundry sand technology using new, modified, inorganic binders. The results of investigations regarding the effect of multiple reclamation on the technological properties of foundry sands with inorganic binders were presented in a concise manner. The reclaim sand were introduced to moulding sands prepared with the new, modified, inorganic binders bonded by the chemical reaction or by blowing with gaseous CO2. Attention was focussed on the effect of multiple reclamation on the residual strength and bench life properties of moulding sands prepared with the new types of inorganic binders.


We obtain the lowest energy solutions for the skymion field equations and their corresponding vortex structures. Two nondegenerate solutions emerge with their vortex swirls in opposite directions. The solutions are associated with an extremum property, which favors an array of almost hexagonal shape. We predict that a regular hexagonal lattice must have a mix of skyrmions of both swirls. Although our solutions could not keep the norm of the magnetization constant at unity, their greatest deviation from unity occurred in regions where the spins are far from planar; we show how to improve this situation.


Proposals to limit the number of overtime hours are held to be in the tradition of social reform of factory conditions. In a modern industrial context, overtime is defined to be those hours over which employees may exercise discretion. The impact of legislation and trade unions upon hours of work in the UK and the USA is examined and found generally to be secondary to that of market pressures. In pressing for limitations upon hours of work, trade unions have insisted upon maintaining the level of real earnings. In part, this is explained by the recognition that, without the opportunity or the ability to acquire saleable skills, low-paid employees have only long hours to offer as a means of achieving 'adequate wages'. Earnings are two-dimensional, the product of wage rates and hours of work. In its impact upon earnings, the imposition of greater uniformity upon the latter would create problems akin to those raised by the attempt to reduce wage differentials. This assertion is backed by evidence from the UK on the distribution of overtime by age, sex and occupation. The argument that a cut in overtime hours would provide the basis for job creation during a period of chronic unemployment is undermined by the necessity to reduce labour costs per unit of output.


The prevalence of attention-deficit/hyperactivity disorder (ADHD) has been increasing these days, and this phenomenon has raised the interest and attention of both society and the academy. While ADHD is believed to be one of the most common mental disorders in children, it may be essential to track back how to prevent such a disease to avoid further deficits in children's cognitive functions affected by the early prevalence of ADHD. This paper reviews the possible causes of ADHD based on previous research. The results show that the dimension of causes could be split into three types: neutral or biological-related causes, natural and behavioral causes, and cognitive function deficit. With all these mentioned factors contributing to the prevalence of ADHD, and with a deeper knowledge of ADHD, the prediction of ADHD could be more high-efficient.


Recent works suggest that the use of ionic liquids in the copper solvent extraction industry is feasible. However, the reports did not use real solutions (or synthetic solutions with various elements). This fact remains poorly established, and the interaction efficiencies are still under study. The objective of this research is to explore the extraction and stripping of the four major elements present in a copper industrial pregnant leach solution (Cu(II), Fe(III), Mn(II), and Zn(II)) using the methyltrioctyl/decylammonium bis(2,4,4-trimethylpentyl)phosphinate (R4NCy) ionic liquid as an extractant. The work conditions studied in extraction were ionic liquid concentration, initial pH, and O/A ratio, and in stripping were H2SO4 concentration and O/A ratio. The test was carried out at room temperature and ambient pressure. High efficiency and selectivity (99.82% and 113,755 over Cu(II), respectively) were observed for Fe(III) extraction over the other elements. Moreover, after the extraction test, significant difficulty in stripping Fe(III) loaded in the ionic liquid was observed (28.7% at 0.5 M of H2SO4). Finally, the present study demonstrates that the R4NCy ionic liquid is not suitable for copper extraction because it has a higher selectivity for Fe(III) and Zn(II).


The objective of this study was to determine the effect of supplementating 10 g/animal/day of Saccharomyces cerevisiae1077 (SC1077) or Saccharomyces boulardii1079 (SB1079) on dry matter intake (DMI), daily weight gain (DWG), feed efficiency (F:G), in vivo digestibility, pH, and rumen ammonia nitrogen (NH3-N) concentration in rumen liquor, as well as progesterone concentration (P4). Twenty four, six-month old, Holstein heifers were randomly assigned to three treatments (n=8): (T1: Control; T2:10 g/animal/day of SC1077; T3:10 g/animal/day of SB1079). Samples of rumen liquor were taken at 60, 120 and 180 d of the experiment to determine pH and ammonia nitrogen. Determination of in vivo digestibility of DM, NDF, ADF and N was carried out 14 days before the of 60, 120, and 180 d periods. Blood samples were taken to measure P4 concentration. No differences (P > 0.05) were found for DMI, DWG, and F:G from supplementing with S. cerevisiae. Similarly, no differences were reported for rumen pH and rumen NH3-N concentration were not affected (P > 0.05), and in vivo digestibility of DM, NDF, ADF and N (P > 0.05). The P4 concentration was similar (P > 0.05) among the treatments. It is concluded that supplementing Holstein heifers with SC1077 and SB1079 did not improve heifers performance nor modified the progesterone concentration.


Fowler-Nordheim (F-N) stress is reported to be one of the most severe wear-out mechanisms for high-frequency MOSFET applications like PAs and RF switches. Previous studies of this degradation process were limited to the DC-static case only and standard empirical models were proposed. In this work a novel general physical model is developed, which correctly describes the ageing of electrical parameters under DC stress. This is made possible by taking into account the hole injection into the gate oxide. Finally this study extends the understanding of F-N degradation to RF regime. In this case a quasi-static sum of the degradation rate is adopted to accurately model and predict the performance worsening; the wear-out shows no frequency dependency in the range up to 4Ghz.

This granted funded research into the application of nanoscience to Li-ion batteries. Different synthesis strategies were employed to create a nanofiber electrode (based on tin-oxide) and a honeycomb electrode (carbon). In both cases, we showed that the nanostructured material was capable of delivering dramatically increased specific capacity (mAh/g) upon discharge when compared to conventional film electrodes. This ability is due to the decreased solid-state diffusion distance of the Li-ion in the nanostructured electrodes. The nanofiber-SnO{sub 2} electrode was created by the template synthesis method. Briefly, a precursor solution impregnates the monodisperse nanoscopic pores of a sacrificial template membrane. The pores run the membrane's entire length. The precursor solution is then processed to the desired material, here using sol-gel chemistry, and the template is removed. This leaves nanostructures of the desired product intact and extending from a substrate like the bristles of a brush. This research topic combines this nanofabrication technique with the Sn-based anode. Tin-oxide based composites have shown great promise as an alternative material for Li-ion battery anodes. This material is electrochemically converted to composite Sn/LiO{sub 2} electrodes. In this form, they are theoretically capable of storing twice the amount of Li as carbon, the current commercial anode. Wemore » showed important improvements in rate-capabilities and cycle-life of this Sn-based nanoscale electrode compared to a thin-film electrode of the same material. Rate-capabilities are a measurement of the specific capacity able to be delivered at increasing discharge rates (1C = 1/h). Figure 1 compares the rate capabilities of the nanostructured electrode to that of the film control electrode. This report shows the nanostructured material was capable of delivering dramatically increased specific capacity (mAh/g) upon discharge when compared to conventional film electrodes.« less


Research analyzes the Intra industry Trade in Manufacture Sector between Indonesia and other countries such as Malaysia, Singapore, Thailand and Philippines. It also analyzes the relationship of industrial sectors in the economic field, especially among countries at ASEAN-5. The intra industry trade is measured based on Grubel-Lloyd Index with the aggregation rate of three digits in the ISIC (International Standard Industrial Classification). Panel data analysis tool is employed to analyze the factors influencing intra industry trade. Result of research indicates that the intensity of the intra industry trade between Indonesia and ASEAN-4 is relatively higher and consistent with that during 1998-2007. The dominant product in the intra industry trade is iron and steel metals. Market structure, product differentiation, and foreign investment, positively and significantly, influence the intra industry trade between Indonesia and ASEAN-4 countries. Machinery, equipment, and electric tool industry is the highest-rank sector based on its forward linkage coefficient. The machinery, equipment, and electric tool industry sector is important to support the growth of other sectors. With respect to the direct backward linkage coefficient, the sector with highest coefficient is the base industry of iron and steel. It shows that base industry of iron and steel sector gives enough great contribution to other sector.


Small chiral organic molecules with CD properties are in high demanded due to their potential use in promising electronic and biological applications. Herein, we reveal a system in which the oxidation of a phosphino group to corresponding phosphine oxide on the inner rim of a helicene derivative induces a CPL response. Laterally π-extended 7,8-dihydro[5]helicenes 1 and 2 bearing phosphine and phosphine oxide groups, respectively, on their inner helical rims (i.e., the C1-position) were synthesized and their helical structures unambiguously determined by X-ray crystallography. The photophysical (UV/visible and emission) and chiroptical properties of these compounds were investigated in various solvents. Despite their structural similarities, 2 showed a significant CPL response compared to that of 1 , with a high dissymmetry factor for emission (| g lum | = (1.3-1.9) × 10 -3 ) that is attributable to structural changes in the interior of the helicene helix.

During the first months of operation (March, 1954 to Sept. 1955) of the new oceanarium, Marineland of the Pacific, we have had numerous opportunities to observe the dolphins and porpoises of California waters. In addition, we have recorded the behavior of captive Atlantic bottlenose dolphins ( Tursiops truncatus ). Many members of the staff at Marineland have assisted in making these observations. We are particularly grateful to Frank Brocato, Captain of the collecting vessel, Geronimo , and his assistant, Frank Calandrino, for their help in compiling the field observations. We wish to thank Dr. Leonard L. Mortimer D.V.M., for his assistance and suggestions during treatment of captive animals. Dr. Raymond Gilmore has given us much assistance and has critically reviewed the manuscript.

We follow Norman and Fraser (1940) in their definition of the terms porpoise and dolphin; porpoise refers to members of the Delphinidae which are small, beakless, and with triangular dorsal fins and tricuspid teeth. Dolphin is used for the remainder of the family, except those larger forms dignified by the name, whale .

This species ( Lagenorhynchus obliquidens Gill, Pl. I, Top) and the common dolphin ( Delphinus bairdi ) have been observed many times more than these data indicate, particularly during the months before Marineland of the Pacific was completed. These observations serve to strengthen the conclusions we draw here.

A new mitochondrial targeting fluorescent probe is designed, synthesized, characterized, and investigated. The probe is composed of three moieties, a BODIPY platform working as the fluorophore, two triphenylphosphonium (TPP) groups serving as mitochondrial targeting moiety, and two long highly hydrophilic polyethylene glycol (PEG) chains to increase its water solubility and reduce its cytotoxicity. As a mitochondria-selective fluorescent probe, the probe exhibits a series of desirable advantages compared with other reported fluorescent mitochondrial probes. It is readily soluble in aqueous media and emits very strong fluorescence. Photophysical determination experiments show that the photophysical properties of the probe are independent of solvent polarity and it has high quantum yield in various solvents examined. The probe also has good photostability and pH insensitivity over a broad pH range. Results obtained from cell viability tests indicate that the cytotoxicity of the probe is very low. Confocal fluorescence microscopy colocalization experiments reveal that this probe possesses excellent mitochondrial targeting ability and it is suitable for imaging mitochondria in living cells.


Sensitivity analysis measures the influence of a Bayesian network's parameters on a quantity of interest defined by the network, such as the probability of a variable taking a specific value. Various sensitivity measures have been defined to quantify such influence, most commonly some function of the quantity of interest's partial derivative with respect to the network's conditional probabilities. However, computing these measures in large networks with thousands of parameters can become computationally very expensive. We propose an algorithm combining automatic differentiation and exact inference to efficiently calculate the sensitivity measures in a single pass. It first marginalizes the whole network once, using e.g. variable elimination, and then backpropagates this operation to obtain the gradient with respect to all input parameters. Our method can be used for one-way and multi-way sensitivity analysis and the derivation of admissible regions. Simulation studies highlight the efficiency of our algorithm by scaling it to massive networks with up to 100'000 parameters and investigate the feasibility of generic multi-way analyses. Our routines are also showcased over two medium-sized Bayesian networks: the first modeling the country-risks of a humanitarian crisis, the second studying the relationship between the use of technology and the psychological effects of forced social isolation during the COVID-19 pandemic. An implementation of the methods using the popular machine learning library PyTorch is freely available.


North Dakota secondary agricultural mechanics instructors were surveyed regarding instructional methods and materials, safety practices, and equipment used in the agricultural mechanics laboratory. Usable responses were received from 69 of 89 instructors via self-administered mailed questionnaires. Findings were consistent with results of similar studies. Instructors were not using recommended safety practices or providing student safety and emergency equipment to the extent warranted by the hazards present in the laboratory. Instructional techniques most commonly used in safety instruction were demonstrations conducted by students and instructors in use of power tools. Most instructors (94.2 percent) required students to pass safety examinations. Instructors used safety manuals and booklets and worksheets most often as instructional materials. Industrial-quality eye protection and welding gloves were the most frequently available safety equipment for student use. The most frequently available safety practices, equipment, or materials were as follows: welding booths with screens/curtains, welding exhaust system, safety guards on all equipment, first aid kits/boxes, fire extinguishers, fire alarms, and marked exits.

A new theropod dinosaur, Shidaisaurus jinae gen. et sp. nov., has been described on the basis of an incomplete skeleton. The specimen was found near the base of the Upper Lufeng Formation (early Middle Jurassic) in Yunnan, China. It is the first theropod dinosaur from the Middle Jurassic of Yunnan. Shidaisaurus jinae is distinguishable from other Jurassic theropods by certain features from the braincase, axis, and pelvic girdle. The absence of any pleurocoels in the axis or in any anterior dorsal vertebrae suggests that the new Lufeng theropod is relatively primitive and more plesiomorphic than most of the Middle to Late Jurassic theropods from China. Most Chinese taxa of Jurassic theropod dinosaurs have not been well described; a further detailed study will be necessary for us to determine their phylogenetic relationships with Shidaisaurus jinae.


Abstract
During the last few decades, there have been significant divergences in the flows of foreign direct investment (FDI) as per decisions taken by multinational companies (MNCs), and many of the developing nations in the Asia and Pacific region are most remarkable in this regard (UNCTAD, 2015). Apart from various economic factors, some sociopolitical issues have also been identified as influencing the FDI decisions. This study investigates the comovements of the standard measures of terrorist activities and MNCs' decision on FDI in selected developing countries in the Asia and Pacific region by employing Generalized Method of Moment (GMM) estimation technique on constructing a balanced panel for 1990–2016. Results summarize that FDI inflows are negatively influenced by terrorist activities in the developing economies of the Asia and Pacific region.


The design of a large measurement-volume metrological atomic force microscope (AFM) is presented. The translation of the sample is accomplished with multiple stages which allow for separate 'coarse' and 'fine' motion. Interferometers and autocollimators are used to measure the position and orientation of the sample. The instrument does not attempt to control position via feedback from the interferometers, thereby allowing use of readily available commercial translation stages and controllers.


This paper explores the relationship between truth and loyalty as it pertains to epistemic issues within contemporary Western politics. One now familiar concern is how an increasing number of people determine their beliefs according to what demonstrating loyalty to their group requires instead of the facts of an independent and objective reality, as a proper concern for truthfulness demands. Whereas "they" base their beliefs on what is required to demonstrate loyalty to their group, "our" beliefs are justified by facts and evidence. Such contrasts pit loyalty and truth as necessarily antagonistic. This paper gives us further reason for thinking that putting loyalty against truthfulness at some very general or conceptual level is deeply misguided. More significantly, it seeks to show that the more helpful contrast to make is between those who are loyal to identities that value truthfulness in such a way that there are no other parts of that identity which are not revisable if they come into conflict with truth, and those who are loyal to identities that subordinate truth to other ends or goals. Acknowledging this allows us to better appreciate various aspects of how the relationship between truth and loyalty is playing out in contemporary politics. Chief among these is how our own commitment to truthfulness is itself embedded in a particular identity, an identity that we not only often fail to acknowledge as such but which necessitates us thinking harder about the ways in which it might itself sustain the dynamics of conflict and contestation, antagonizing those who do not share it and driving them farther away from the truthfulness we extol.


Well-ordered nanostructures were produced on industrial aluminum foils by one-, two-, and three-step anodizing processes performed in sulfuric acid at cell potentials between 15 and 25 V. Almost perfect triangular lattices of nanopores were obtained by the two- and three-step anodizing processes. It was found that the third step in the anodizing process neither significantly improves the ordering of the pores nor enlarges the size of the well-ordered domains. The effective growth rate of the oxide layer was calculated for various cell potentials and compared with literature data. The effect of the anodizing time on the ordering of pores and the size of the domains was established. The pore diameters and the interpore distances were evaluated for various cell potentials, too. Anodizing in sulfuric acid results in small pore sizes and interpore distances compared to the ones obtained by anodizing in phosphoric and oxalic acids.


In order to perform a project, all project managers are facing with high quality standards and benefiting from shortest period of time, possible resources and continuous fights. There are a lot of social and economic factors for a project manager to have an optimized benefit from limited accessible resources either from man power point of view or reserve of materials. Various tools and several techniques are introduced within recent decades for scheduling of projects, but most of them are involved with scheduling of single projects and least for multi-projects. We can model different Courses of Action (COAs) evaluated during the operational military planning as many different activity networks. The corresponding project scheduling model is sufficiently general to be able to represent the most part of military missions. Recently, a project scheduling mathematical model has been proposed where each activity called an action in the military context has different execution modes depending on the resource combination selected. This paper is a combination of Simulated Annealing Algorithm and the best Priority rules for solving the problem of scheduling in multi projects with limited resources that has been tested with numerical examples. The numerical tests make it clear that proposed method is better than multi-applicable rules of scheduling.


Within the building evacuation context, wayfinding describes the process in which an individual located within an arbitrarily complex enclosure attempts to find a path which leads them to relative safety, usually the exterior of the enclosure. Within most evacuation modelling tools, wayfinding is completely ignored; agents are either assigned the shortest distance path or use a potential field to find the shortest path to the exits.

In this paper a novel wayfinding technique that attempts to represent the manner in which people wayfind within structures is introduced and demonstrated through two examples. The first step is to encode the spatial information of the enclosure in terms of a graph. The second step is to apply search algorithms to the graph to find possible routes to the destination and assign a cost to the routes based on their personal route preferences such as "least time" or "least distance" or a combination of criteria. The third step is the route execution and refinement.

In this step, the agent moves along the chosen route and reassesses the route at regular intervals and may decide to take an alternative path if the agent determines that an alternate route is more favourable e.g. initial path is highly congested or is blocked due to fire.


Background Atherosclerosis (AS) is closely related to stroke and cardiovascular diseases. Nuclear factor kappa-B (NF-κB) is the master regulator of inflammation, and thus, modulating the transcription of NF-κB can improve AS. Methods In this study, we conducted a bibliometric analysis to identify the frontiers, hotspots, and features of global research output on NF-κB in AS from 2000 to 2021. Papers published from 2000 to 2021 and the recorded information were retrieved from the Science Citation Index-Expanded of the Web of Science Core Collection. Bibliometric analysis and visualization were performed using VOSviewer and CiteSpace, including an analysis of the general distribution of annual output, highly productive countries, active journals, active institutions and authors, keywords, and co-cited references. Results A total of 5,439 original articles and reviews were retrieved and analyzed, and the results indicated that the annual number of publications on NF-κB in AS has been increasing in waves over the past 22 years. The majority of papers were published in China, while the USA had the highest number of citations and H-index. The most productive affiliation and journal were the University of California System and Arteriosclerosis Thrombosis and Vascular Biology, respectively. The papers of Chiu JJ. received the highest number of citations globally in 2011. The keywords, "nlrp3 inflammasome" and "microRNA", have recently attracted considerable attention, and very frequently occurring keywords included "NF kappa B", "atherosclerosis", "expression", "activation", "endogenous cell", and "oxidative stress". New keywords in 2021 included "muscle", "attenuates atherosclerosis", "mesenchymal transition", "metabolic disorder", and "palmitic acid". Conclusions AS and inflammation have become research hotspots lately. Over the past decade, most studies have focused on basic research, and pathways associated with the regulatory role of NF-κB in AS have become a particular focus in recent studies. Moreover, our study revealed that NF-κB plays a remarkable role in AS and may be a therapeutic target.


In order to solve the membrane fouling problem which impedes the application of anaerobic membrane bioreactor,a submerged anaerobic membrane reactor with the capacity of 20 m3/d was developed.40 m2 rotary membrane modules are set inside and annular aqueduct design is applied to ensure the separation effect and uniformity of water distribution as well as achieve the online back washing.The reactor is applied to treat the food wastewater for 5 months,the organic removal rate can reach more than 95%,and the COD in the effluent is less than 50 mg/L.When the rotation speed of membrane module is 250 r/min,the maximum stable membrane flux can reach 20 L/(m2·h) with no CIP online and offline cleaning.In mid-temperature environment,the yield of methane can reach more than 55% which indicates the recycling efficiency is very high.Comparing to the traditional external membrane reactor,the energy can be saved at least by 32%.


PRIDE is a hierarchical multiresolutional framework for moving object prediction that incorporates multiple prediction algorithms into a single, unifying framework. PRIDE is based upon the 4D/RCS (Real-time Control System) reference model architecture and provides information to planners at the level of granularity that is appropriate for their planning horizon. This framework supports the prediction of the future location of moving objects at various levels of resolution, thus providing prediction information at the frequency and level of abstraction necessary for planners at different levels within the hierarchy. To date, two prediction approaches have been applied to this framework. In this paper, we provide an overview of the PRIDE (Prediction in Dynamic Environments) framework and describe the approach that has been used to model different aggressivities of drivers. We then explore different aggressivity models to determine their impact on the location predictions that are provided through the PRIDE framework. We also describe recent efforts to implement PRIDE in USARSim, which provides high-fidelity simulation of robots and environments based on the Unreal Tournament game engine.


Real-world physical signals are commonly nonstationary, and their frequency details change with time and do not remain constant. Fourier transform that uses infinite sine/cosine waves as basis functions represents frequency constituents of signals but does not show the variations of the signal frequency contents over time. Multiresolution demonstration of the time-frequency domain may be achieved by the techniques that can support adjustable resolution in time and frequency. Earthquake strong motion signals are nonstationary and indicate time-varying frequency content due to the scattering from the source to the site. In this paper, we applied short-time Fourier transform, S-transform, continuous wavelet transform, fast discrete wavelet transform, synchrosqueezing transform, synchroextracting transform, continuous wavelet synchrosqueezing, filter bank synchrosqueezing, empirical mode decomposition, and Fourier decomposition methods on the near-source strong motion signals from the 7 May 2020 Mosha-Iran earthquake to study and compare the frequency content of this event estimated by these methods. According to the results that are examined by Renyi entropy and relative error, synchroextracting performed better in terms of energy concentration, and the Fourier decomposition method revealed the lowest difference between the original and reconstructed records.


Abstract Factors important in designing" a cathodic protection system for glass lined domestic hot water heaters are considered. Method by which bare areas of single coated glass lined tanks can be calculated is explained, and comparisons are made between calculated values and those obtained by tests on tanks under protection. Instruments for making these tests and techniques are illustrated and described. Design data relevant to required current densities are considered with respect to platinum clad tantalum and platinum plated titanium anodes. Regulations of Underwriters' Laboratories concerning accumulated gas from cathodic protection systems are weighed against test results and the volume of gas actually produced is measured and analyzed.

We describe MSR-MT, a large-scale example-based machine translation system under development for several language pairs. Trained on aligned English-Spanish technical prose, a blind evaluation shows that MSR-MT's integration of rule-based parsers, example based processing, and statistical techniques produces translations whose quality in this domain exceeds that of uncustomized commercial MT systems.


Red spruce (Picea rubens Sarg.) decline has been observed in northeastern North America for the last 30 years. A major inciting stress involved in this decline is freezing injury of foliage. The objectives of this study were the following: (i) to examine how photosynthesis, needle electrolyte leakage, chlorophyll loss, needle reddening, needle loss and bud break respond to single freezing events down to −45 °C on 3-year-old seedlings; (ii) to test if faster thawing rates increase the amount of freezing injury; and (iii) to measure how Rhizosphaera kalkhoffii Bubak inoculations interact with freeze-injured needles. Two trials, one of 60 seedlings and one of 80 seedlings, were conducted. The second trial had half the seedlings covered with plastic bags for doubling the thawing time. Photosynthesis, as measured by gas exchange, was consistently the most sensitive measure, detecting nonvisible injury on uncovered seedlings (p < 0.05) at −25 °C. Measurements detecting freezing damage on covered, slower thawing...

This article reports on a series of annual surveys of how a panel of experts expect usage of online channels to develop between now and 2010 in Europe and North America. The bursting of the internet bubble is not expected to reduce consumer usage of the Web for e-commerce. Indeed, in the latest survey, the experts again revise upwards their earlier predictions of European online adoption and usage in the home. The survey covers the following: online access at home; consumer choice of access channels; volume of e-commerce and each channel's relative importance; the impact of mobile; barriers to B2C e-commerce; and regional differences.


This study proposes an efficient back mapping model that uses a lightweight neural network and virtual calibration plate to accurately correct the distortion of low quality wide angle camera. Unlike the radial model, the neural-based method uses non-linear functional mapping to model surface distortion, which consists of wide-angle distortion and various manufacturing errors in low-cost cameras. The proposed approach uses a lightweight multilayer feed-forward neural network (MFFNN) with error back-propagation training algorithm to map the complex distortion surface. The optimal number of neurons of hidden layer was assigned as 4 for associating the mapping model between the distortion image space (DIS) with the correction image space (CIS). This study uses a 105 degree wide-angle low-cost camera to test the proposed method. Results show that the maximal corrected error in a whole image is less than 2 pixels, and that the mean square error (MSE) approaches 0.2542 between the corrected and ideal results.


Parental parenting is very important for child development, especially early childhood. Early childhood is a very sensitive time, because parents must be able to provide positive things to help children's psychological and mental growth as well as the community in Timbang Lawan Bahorok Village. In the implementation of the study we used the interview method as an instrumental tool. During a visit to the village of Timbang Lawan Bahorok we found that many parents ignored the impotance of parenting and support involving children. We also see a lack of parental readness in educating. They think that the role of parents is an easy thing, which is only limited to feeding, sending and caring, but basically parents are the main key to the child's psychic and emotional development. As parent's, they should pay more attention, understand and get closer to the child. If the parenting style given by the parents is good, the child will bring out a good attitude and have good character.


After the policy to replace the business tax with a value-added tax was launched, local finance has encountered greater difficulties. In recent years, the economic downward pressure has made the dilemma far more serious. Some scholars, even from state level, showed some intentions of recommending that the consumption tax should be changed from the current central tax to a local tax or a shared tax to relieve the pressure of local governments. In this paper, we proved by presenting recent year's tax figures of business, consumption, and local and central fiscals and their growth rate that replacing the consumption tax with a local tax does not exactly correspond to the trend of China's reform of the financial system, the functional orientation of the consumption tax, and the nature of the consumption tax itself and may trigger some problems, and it may still be a better choice for the consumption tax to serve as a central tax.


This article demonstrates how digital games can confirm or subvert national historical discourses. The author analyzes selected 20th-century French historical adventure digital games about absolutist France and the subsequent French Revolution. Although most of them focused on reconstructing the era (e.g., the state-funded Versailles 1685), the emphasis is placed on two games by Patrick Beaujouan (Le Passager du temps and Conspiration de l'an III). Their subversive content undermined the sense of reconstructing historical events on the screen. However, as the author concludes, the subversive content of Beaujouan's games had its prize because they lacked the technical and institutional support that restorative projects such as Versailles 1685 had. However, Beaujouan's games show that every "historical" game tells us more about contemporary discourses than past events.
