A Coordinated Charging/Discharging Strategy for Electric Vehicles Based on Price Guidance Mechanism

In view of the contradiction between the rapid growth of electric vehicles ownership and the imbalance of electric vehicles’ charging demand and the lower distribution network service ability, a coordinated charging/discharging strategy maximizing the discharge depth on the basis of satisfying the charging demand of electric vehicles is proposed. This paper analyses the relationship between the charging/discharging time intervals of electric vehicles and the division of time-of-use electricity price, the vehicles’ arrival/departure time and the daily driving mileage. Take minimizing load fluctuation as the objective and take meeting the charging demand of electric vehicle users as the restrains based on time-of-use electricity price. Monte Carlo simulation and PSO algorithm are used for simulation and calculation. The results show that with the coordinated charging and discharging strategy, it can not only realize the peak load shifting, but make the customers’ charging cost lower.
Nontunnelling high-order harmonics from ultra-intense laser-driven tightly bound systems

High-order harmonic emission is investigated by numerical solution of the weakly relativistic, two-dimensional Schrödinger equation for the case of ultra-intense laser-driven tightly bound systems (for example, multiply charged ions such as O7+ exposed to laser fields of the order of 1018 W cm-2 at 248 nm). In contrast to their usual substantial decrease, the low-order harmonics having an energy less than the ionization potential exhibit a high-efficiency (i.e. intense) plateau with a well defined cutoff. The shape of this plateau is found to depend on the shape of the binding potential. A classical `surfing' mechanism for the generation of these harmonics is proposed that does not involve tunnelling and that nevertheless explains the observed cutoff. Thus we call them `nontunnelling harmonics'. The significance of relativistic effects for these harmonics is investigated and found to be small, despite the high laser intensity, because of the absence of tunnelling.
Digital health technology and diabetes management

Diabetes care is largely dependent on patient self‐management and empowerment, given that patients with diabetes must make numerous daily decisions as to what to eat, when to exercise, and determine their insulin dose and timing if required. In addition, patients and providers are generating vast amounts of data from many sources, including electronic medical records, insulin pumps, sensors, glucometers, and other wearables, as well as evolving genomic, proteomic, metabolomics, and microbiomic data. Multiple digital tools and apps have been developed to assist patients to choose wisely, and to enhance their compliance by using motivational tools and incorporating incentives from social media and gaming techniques. Healthcare teams (HCTs) and health administrators benefit from digital developments that sift through the enormous amounts of patient‐generated data. Data are acquired, integrated, analyzed, and presented in a self‐explanatory manner, highlighting important trends and items that require attention. The use of decision support systems may propose data‐driven actions that, for the most, require final approval by the patient or physician before execution and, once implemented, may improve patient outcomes. The digital diabetes clinic aims to incorporate all digital patient data and provide individually tailored virtual or face‐to‐face visits to those persons who need them most. Digital diabetes care has demonstrated only modest HbA1c reduction in multiple studies and borderline cost‐effectiveness, although patient satisfaction appears to be increased. Better understanding of the barriers to digital diabetes care and identification of unmet needs may yield improved utilization of this evolving technology in a safe, effective, and cost‐saving manner.
Fenologia reprodutiva de espécies vegetais da Floresta Ombrófila Mista do Paraná, Brasil

The Mixed Ombrophilous Forest (FOM) or Araucaria Forest, vegetation that occupies regions with a highly seasonal climate subject to frost, used to cover 40% of Parana State. Nowadays, however, there is less than 1% of advanced and well conserved FOM covering this State. This study presents the reproductive phenological patterns (flowering and fruiting) of the plant species found in FOM fragments located in three municipalities of Parana State in order to subside restoration activities. Monthly phenological observations in 543 individuals of 145 species, representing several life forms (71 trees, 52 bushes, 18 vines and four epiphytes) were conducted between January 2004 and December 2005 employing the activity index. Flowering was recorded mainly between September and December, with a peak in October and November (68 species), followed by fruiting, which was concentrated between December and April, peaking in February (61 species). During the coldest months (June to August), the number of species with flowers or fruits was very low, with less than five species per phenophase. The availability of araucaria (Araucaria angustifolia (Bertol.) Kuntze) seeds varied between the years, but usually occurred between April and September. Significant correlations between phenophases and some abiotic factors, especially day length and temperature, were found. Therefore, plant species of the FOM proved to be highly seasonal, with periods of high and low flowering and fruiting activity, as consequence of the climatic seasonality, characteristic of the study region.
Combustion State Recognition of Flame Images Using Radial Chebyshev Moment Invariants Coupled with an IFA-WSVM Model

Accurate combustion state recognition of flame images not only plays an important role in social security, but also contributes to increasing thermal efficiency and product quality. To improve the accuracy of feature extraction and achieve the combustion state recognition, a novel method based on radial Chebyshev moment invariants (RCMIs) and an improved firefly algorithm-wavelet support vector machine (IFA-WSVM) model is proposed. Firstly, the potential flame pixels and the potential flame contour are obtained in the pre-processing phase. Then, the rotation, translation and scaling (RTS) invariants of radial Chebyshev moments are derived. Combing the region and contour moments, the RCMIs of pre-processed and edge images are calculated to construct multi-feature vectors. To enhance the recognition performance, an IFA-WSVM model is built, where the IFA is applied to search the best parameters of WSVM. Then, the IFA-WSVM model is used to recognize the combustion state. Finally, the result for case studies show that the proposed method is superior to methods based on HMIs and ZMIs, achieving the highest rate of 99.07% in real time. The IFA algorithm also outperforms other benchmark algorithms. Even for the images transformed by RTS and small size of training sets, the proposed method continues to exhibit the best performance.
Adición de bloqueante del receptor de angiotensina II en la insuficiencia cardiaca descompensada

FUNDAMENTO: Durante a descompensacao da insuficiencia cardiaca, ocorre uma intensa ativacao do sistema renina-angiotensina-aldosterona, entretanto, o uso de inibidor da enzima de conversao de angiotensina (IECA) nao pode bloquea-lo completamente. De outro modo, a adicao de bloqueador do receptor de angiotensina II (BRA) pode ser util quando ocorre a dependencia de inotropico. Avaliamos a eficiencia da associacao BRA-IECA para retirada da dobutamina na insuficiencia cardiaca avancada e descompensada. OBJETIVO: Avaliar a eficacia da associacao de bloqueador do receptor AT1 de angiotensina II ao inibidor de enzima de conversao, para a retirada da dobutamina em pacientes com dependencia de suporte inotropico decorrente da descompensacao aguda da insuficiencia cardiaca cronica. METODOS: Em um estudo caso-controle (N = 24), selecionamos pacientes internados por descompensacao da insuficiencia cardiaca e com uso por mais de 15 dias de dobutamina, ou uma ou mais tentativas sem sucesso de retirada; dose otimizada de IECA; e FEVE < 0,45. Os pacientes entao receberam adicionalmente BRA (n = 12) ou nao (controle, n = 12). O desfecho foi o sucesso na retirada da dobutamina, avaliado pela regressao logistica, com p < 0,05. RESULTADOS: A fracao de ejecao foi de 0,25, e a idade de 53 anos, com dose de dobutamina de 10,7 μg/kg.min. O sucesso na retirada de dobutamina ocorreu em oito pacientes do grupo BRA (67,7%), e em dois no grupo controle (16,7%). A "odds ratio" foi de 10,0 (intervalo de confianca de 95%:1,4 a 69,3; p = 0,02). A piora da funcao renal foi semelhante (grupo BRA: 42% vs. grupo controle: 67%, p = 0,129). CONCLUSAO: Neste estudo piloto, a associacao BRA-IECA foi relacionada ao sucesso na retirada da dobutamina, na insuficiencia cardiaca avancada descompesada. A piora da funcao renal foi semelhante em ambos os grupos. Estudos adicionais sao necessarios para esclarecer o assunto.
Comprehension Efficiency of Graphically Presented Ordered Sets

Untersucht wurden Effekte sogenannter visueller Eigenschaften (Kreuzungsfreiheit, Kantenneigung, Ebenen) auf die Verstandnisgeschwindigkeit von Halbordnungen, die als Hasse-Diagramme dargeboten wurden. In jedem von 3 Experimenten beantworteten Versuchspersonen Interpretationsfragen, die Vergleiche zwischen Elementen der Halbordnung erforderten. Das Wissen der Vpn variierte zwischen den Experimenten. Die Analyse der Antwortlatenzen mit einem nonparametrischen Modell zeigt, das Kreuzungsfreiheit die wichtigste Variable ist, unabhangig von Kantenneigung und Ebenen. Erste Prinzipien fur die Gestaltung von Hasse-Diagrammen konnten abgeleitet werden. Hypotheses and Model Upward drawings or Hasse diagrams play a central role in the (automatic) visualization of non-numerical data structures. Therefore, mathematicians and computer scientists (see, e.g., Rival, 1993) have proposed visual properties such as planarity, slopes and levels (see Figure 1). Attributes with subscript 1 Figure 1: Visual properties (planarity, slopes, levels) and their attributes should make comprehension of graphically presented ordered sets more efficient compared to attributes with subscript 2.

They can be put together in a non-parametric model which is depicted in Figure 2. Each node in this model is labelled with a triple (pi, sj, lk) representing a type of diagram, e.g., (p1, s2, l1) denotes a non-crossed, slanted, and horizontal diagram. The hierarchy of diagrams in the model form itself an ordered set. For example, diagram (p2, s2, l2) should be comprehended least efficiently, whereas (p1, s1, l1) should be most efficiently to comprehend. (p2, s2, l1) and (p2, s1, l2), however are not comparable with respect to comprehension efficiency, as well as (p1, s2, l1) and (p1, s1, l2). The model predictions were tested in three experiments.

On the origin of planetary nebulae.

The stellar wind from a red giant produces an extensive circumstellar cool nebula of appreciable mass. We suggest that in some cases mass loss continues until the hot core of the star is exposed, and that the stellar wind from the remnant star collides with the circumstellar nebula, producing a relatively dense shell of gas which increases in mass and radius at a constant rate. It is shown that such a shell, when ionized by radiation from the central star, has the characteristics of a planetary nebula. V 1016 Cygni is used as an example of a star which has recently undergone the transition from a red giant to a young low-mass planetary nebula.
Modélisation moléculaire de l'hydratation, de la structure, et de la mobilité des ions et de l'eau dans l'espace interfoliaire et à la surface d'une argile smectitique

L’etude de l’adsorption et de la mobilite des ions dans les argiles est importante pour mieux apprehender de nombreux processus geochimiques et environnementaux, de meme que pour predire le comportement des radionucleides dans les conditions du stockage geologique. A cause de leurs tailles tres petites (< 2μm), il n’est pas toujours evident d’etudier les argiles a l’aide des methodes et techniques experimentales existantes. L’une des alternatives a ce probleme consiste alors a utiliser la modelisation moleculaire pour les etudier. En plus de leurs tailles fines, les argiles presentent egalement des structures complexes, qui peuvent survenir en raison de la multiplicite de possibilites de distributions et d’arrangements des substitutions isomorphiques dans leurs couches. Il a ete clairement demontre qu’il existe une correlation entre la distribution des substitutions dans les couches des argiles et les proprietes de ces dernieres. En revanche, ceci reste a demontrer en ce qui concerne l’arrangement de ces substitutions dans les couches de l’argile. Dans ce travail, la modelisation moleculaire est utilisee pour determiner et comparer les proprietes d’hydratation, ainsi que la structure et la mobilite des ions (Li⁺, Na⁺, K⁺, Rb⁺, Cs⁺, Mg²⁺, Ca²⁺, Sr²⁺, Ba²⁺, Ni²⁺, UO₂²⁺) et de l’eau dans l’espace interfoliaire de trois modeles de montmorillonite, differents entre eux par l’arrangement des substitutions isomorphiques dans les couches de l’argile.L’adsorption et la diffusion des cations cites plus haut et de l’eau sont egalement etudiees a la surface de la montmorillonite et les resultats sont compares a ceux obtenus dans l’espace interfoliaire a 298 K et a 363 K. Les resultats obtenus dans ce travail s’accordent bien avec les observations experimentales, et font ressortir une correlation plus ou moins importante entre le modele d’argile utilise et le type de propriete calculee. Cette correlation depend egalement de la nature du cation present dans la structure de la montmorillonite et de sa teneur en eau.
Two-loop QCD corrections to b-->c transitions at zero recoil.

Complete two-loop QCD corrections to {ital b}{r_arrow}{ital c} transitions are presented in the limit of zero recoil. Vector and axial-vector coefficients {eta}{sub {ital A},{ital V}} are calculated analytically in the limit of equal beauty and charm masses, and a series appoximation is obtained for the general mass case. {eta}{sub {ital A}} is crucial for the determination of the absolute value of the Cabibbo-Kobayashi-Maskawa matrix element {ital V}{sub {ital cb}}. The two-loop effects enhance the one-loop corrections by 22{percent}, removing a major theoretical uncertainty in the value of {vert_bar}{ital V}{sub {ital cb}}{vert_bar}. Including two-loop QCD effects and previously neglected electroweak corrections we find {vert_bar}{ital V}{sub {ital cb}}{vert_bar}=0.0383{plus_minus}0.0021(stat){plus_minus}0.0025(syst){plus_minus}0.0011(theory). {copyright} {ital 1996 The American Physical Society. }
Hopf bifurcation with broken circular symmetry

A symmetry-breaking Hopf bifurcation in an O(2)-symmetric system has eigenvalue of multiplicity two. When the circular symmetry is broken these eigenvalues split into two pairs. The consequences of this splitting in the nonlinear regime are analysed in detail. It is found that the perturbation selects the phase of the standing wave (SW) solutions and that two SW branches, differing in phase by pi , bifurcate from the trivial solution in succession. Pure travelling waves (TW) are no longer possible. Instead two new solution branches denoted by TW' and MW' bifurcate from the SW branches in secondary steady-state and Hopf bifurcations, respectively. In contrast to the TW', the MW' only exist at small amplitudes, terminating on the TW' branch in either global or tertiary Hopf bifurcations. These solutions show remarkable resemblance to the states observed in recent experiments on binary fluid convection in large but finite containers.
Fluids adsorbed in narrow pores: phase equilibria and structure

When gases or liquids are adsorbed in narrow pores or capillaries their properties are significantly different from those in a bulk phase. This article reviews recent developments in the statistical theory and computer simulation of simple fluids confined in model pores, emphasizing the microscopic structure and phase equilibria. The structure reflects the packing of atoms or molecules in confining geometries while the phase behavior reflects the presence of surface and bulk contributions to the fluid's free energy. Confinement shifts first-order transitions, such as condensation or freezing, away from their location in bulk; it also alters the location and nature of the bulk critical point reducing the effective dimensionality. Sometimes surface phase transitions such as layering and prewetting compete with shifted bulk transitions giving rise to rich phase diagrams. The extent to which the theorists' results for fluids in single idealized pores might be relevant for solvation force studies probing liquids between crossed mica cylinders and for gas adsorption studies in real mesoporous solids such as VYCOR is mentioned briefly.
Harnessing Mobile Technology for Student Assessment

The primary goal of education is to enhance the knowledge and skills of students in domains that broaden their thinking and prepare them to be lifelong learners in their chosen field of study. Assessment of student learning is an important part of the educational process that provides feedback to the student and instructor to promote learning. Concurrent with the advancements in technology, instructors have harnessed emerging mobile technologies to design more efficient and automated forms of student assessment. We define mobile devices as handheld portable computers that can be operated through touch screen gestures or small keyboards. Tablets fall under the category of mobile devices, but provide several advantages over smartphones, primarily that of having a larger screen without having to carry around a larger (and heavier) laptop computer. Mobile devices are becoming ubiquitous among students and teachers, but are underutilized as tools in education and assessment. However, early adopters of mobile technology are finding novel ways to engage students and are creating new avenues for teachers to assess student learning. Student assessment is defined as the means of collecting data from students regarding their knowledge, skills, and abilities. Summative assessments focus on attaching a score to students’ performance to assign a grade or make individual comparisons. In contrast, formative assessment “. represents information communicated to the learner that is intended to modify the learner’s thinking or behavior for the purpose of improving learning” (Shute, 2007, p. 1). Although mobile devices can dually serve these forms of assessment, we focus primarily on the role of mobile devices in formative assessment. Because of the recency of mobile technology in education, pioneers and leading scholars in the field are often contemporaries. Andy Burkhardt of Champlain College (Burkhardt & Cohen, 2012), Els Koppen at KU Leuven (Koppen, Langie, & Bergervoet, 2013), and Jeffrey Stowell at Eastern Illinois University are some of the pioneers in the field of classroom polling (Stowell & Nelson, 2007). Peter Dunn at the University of the Sunshine Coast, (Dunn, Richardson, McDonald, & Oprescu, 2012), Arnold Froese at Sterling College (Froese et al., 2012), and Jeffrey Kuznekoff at Ohio University (Kuznekoff & Titsworth, 2013) are current leading scholars in the use of mobile devices in the classroom.
Comets and meteorites: relationship (again?)

By testing fireballs, associated with cometary fragments, in the Earth's atmosphere, their depth of penetration, and by comparing their theoretical residual masses with meteorite falls, it is argued that there are also chondrites, besides volatiles, in cometary nuclei. Ordinary chondrites mostly orbit in Apollo-, Amor- and Athenae-type orbits, and carbonaceous chondrites probably predominate in more eccentric orbits whose aphelia are beyond Jupiter. Chondrites probably originate in bodies larger than comets are to-day. The history of the relations between the parental bodies of chondrites and comets should be studied in greater detail
Josephson voltage standards

This paper reviews the present state of modern Josephson voltage standards. The presentation focuses on conventional dc standards based on underdamped superconductor–insulator–superconductor junctions and programmable standards based on overdamped superconductor–insulator–normal conductor–insulator–superconductor junctions. The current developments of ac standards on the basis of pulse-driven arrays and single flux quantum-based voltage multipliers are briefly summarized.
Evaluation of basic performance and applicability of a newly developed in vivo nitric oxide sensor

Direct measurement of nitric oxide (NO) is of great importance and value for both in vitro and in vivo studies on dynamic NO bioactivity. Here, we evaluated the basic performance of a newly developed NO sensor (Innovative Instruments, Inc.). Unlike other NO sensors, the new NO sensor has a highly durable, gas-permeable coating and is affected much less by electrical interference due to its integrated structure where working and reference electrodes are combined in a single element. Calibration with NO gas showed high sensitivity of about 580 pA per nmol-NO l−1 (the detection limit 0.08 nmol-NO l−1, S/N = 3). This sensor also showed high selectivity (25 000 times and more) to NO, compared with NO-related reagents such as L-arginine, NG-monomethyl-L-arginine, acetylcholine, nitroglycerin (NTG) and tetrahydrobiopterin as well as dissolved oxygen. As an in vivo application, the sensor was located in the anaesthetized rat abdominal aorta to measure NTG-derived plasma NO. Intra-aortic infusion of 0.5 mg NTG caused a measurable increase in plasma NO level (2.0 ± 2.2 nmol l−1, mean ±SD, n = 3). In conclusion, the new NO sensor demonstrated a satisfying performance for both in vitro and in vivo applications.
