Running head: YEAR-ROUND EDUCATION IN A REFORM ENVIRONMENT Year-Round Education in a Reform Environment: The Impact on Student Achievement and Cost-Effectiveness Analysis

The purpose of this study was to examine the impact of year-round scheduling on student achievement and attendance and to conduct a cost-efficiency analysis associated with year-round education. Participants were students who attended year-round school in the fourth and fifth grades (N=95) and students who attended schools with traditional calendars at the same grade levels matched on third-grade test scores and socioeconomic status (N=95) . Multivariate and univariate analysis revealed no significant differences between students attending year-round schools and those attending schools with traditional calendars in both reading and math achievement and average percent attendance. Cost-efficiency analysis revealed that year-round schools were more expensive and less cost-effective than the regular-calendar schools in both reading and math. The main conclusion of this research is that the year-round schedule is not a panacea and that there are more elements that have to be taken into consideration when approaching the issue of student achievement. Research results show the need for holistic approaches that incorporate both school and nonschool variables, such as the roles teachers, schools, and parents play that can and do influence student achievement.

Improving Spectral Efficiency and Reducing Adjacent Channel Interference of a Wireless Emergency Communication System

Cellular services have been ineffective in providing defense and disaster recovery communications. Overloads that occur after disasters cause degraded resource access to all users, no matter how important. This has led to the development of the Wireless Priority Service, which will queue emergency calls if they are first blocked. The next generation of Wireless Priority Services, however, must also be able to support more numbers of calls after disaster strikes, which can only be achieved by increasing the spectral efficiency of a system. In this work, we propose to use linear, higher order modulation techniques for priority services instead of the currently deployed non linear modulation schemes used in GSM systems. Linear, higher order modulation techniques increase spectrum efficiency as needed but suffer from spectral regrowth, resulting in increased Adjacent Channel Interference and Inter Symbol Interference. Our work deals with Adjacent Channel Interference, and we presented a new technique to model Adjacent Channel Interference in our earlier work. Here we follow by designing filters to reduce Adjacent Channel Interference. Finally, we show how these linear modulation schemes and interference minimizing filters can be activated as needed using software defined radio.

Trends and Risk Factors for Prisoner Suicide in France

France currently has a very high level of prisoner suicides. Between 2005 and 2010, the mean annual rate was 18.5 suicides per 10,000 prisoners, seven times higher than for the general population. In this article, we begin by describing how suicide has changed since the mid-nineteenth century, highlighting the increasingly specific nature of suicide among prisoners versus non-prisoners. We then analyse the associations between individual characteristics and suicide risk, based on information from the French prison service’s database on all prison terms served in France between 1 January 2006 and 15 July 2009. Over this period, nearly 378,000 terms were observed (corresponding to more than 221,000 person-years) and 378 suicides were identified. Our results confirm the vulnerability of pre-trial detainees, and show that isolation, be it physical or social, is a key component of suicide risk, along with the type of offence resulting in imprisonment. Improving the conditions of detention is one of the priorities of prevention policies now being implemented, but the nature of the offence must also be taken into account as a suicide risk factor.
Charge pump circuit

A charge pump circuit for converting an input voltage to a predetermined voltage. The charge pump circuit includes switching transistors, which are connected in series between an output terminal and reference potential terminal of the charge pump circuit, and a capacitor connected to a node between the first and second transistors. The switching transistors include a first transistor connected to the reference potential terminal and a second transistor connected to the first transistor. The capacitor has a first terminal connected to a node between the transistors and a second terminal connected to a delay circuit. The delay circuit is connected between the second terminal of the capacitor and a control terminal of the first transistor. The delay circuit delays a clock signal received by the control terminal by a predetermined time and provides the delayed first clock signal to the second terminal of the capacitor.
Software architecture of the high-level control of FRIDA

The instrument FRIDA (inFRared Imager and Dissector for Adaptive optics) is an integral field spectrograph (near infrared) operating at the wavelength range of 0.9 to 2.5um with imaging capability for being used at the Nasmyth B platform of the Gran Telescopio de Canarias (GTC). FRIDA is a collaborative project led by the Instituto de Astronomía Universidad Nacional Autónoma de México (IA-UNAM, México) with the collaboration of the Instituto de Astrofísica de Canarias (IAC, Spain), Centro de Ingeniería y Desarrollo Industrial (CIDESI, México), the University of Florida (UF, USA), and the Universidad Complutense de Madrid (UCM, Spain). In imaging mode, FRIDA will provide scales of 0.010, 0.020 and 0.040 arcsec/pixel and, in IFS mode, spectral resolutions of R 1000, 4.500 and 30.000. FRIDA is the first GTC instrument to use the telescope Adaptive Optic (AO) system and it is rescheduled to be delivered to GTC shortly in 2020. Since FRIDA is a GTC instrument, the high-level control software of FRIDA is embedded within the distributed architecture of the System Control of GTC (GCS) and must fulfill the GCS software and hardware standards to control the telescope and the AO system. This paper shows an overview of the high-level control software components of FRIDA inside the GCS architecture. The main components are the Mechanisms Control System whose primary task is to control the mechanisms of FRIDA, the Data Acquisition System that interacts with the detector to take image, the Data Factory Agent whose task is to provide quality control for both engineering and scientific data, the Instrument Library component responsible for operating the devices associated to FRIDA and the Observation Manager component responsible for the execution of the observing sequences in close coordination with the GTC AO system.
Objectivity and Perspective in Empirical Knowledge

Epistemologists generally think that genuine warrant that is available to anyone must be available to everyone who is exposed to the relevant causal inputs and is able and willing to properly exercise her rationality. Â The motivating idea behind this requirement is roughly that an objective view is one that is not bound to a particular perspective. Â In this paper I ask whether the aperspectivality of our warrants is a precondition for securing the objectivity of our claims. Â I draw upon a Sellarsian account of perception in order to argue that it is not; rather, inquirers can have contingent properties and perspectives that give them access to forms of rational warrant and objective knowledge that others do not have. The universal accessibility of reasons, on my account, is not a precondition for the legitimacy of any actual warrant, but rather a regulative ideal governing inquiry and communication.

P o S ( L A T T I C E 2 0 1 6 ) 0 5 5 Roberge-Weiss transition in N f = 2 QCD with staggered fermions and N τ = 6 Owe Philipsen

The QCD phase diagram at imaginary chemical potential exhibits a rich structure and studying it can constrain the phase diagram at real values of the chemical potential. Moreover, at imaginary chemical potential standard numerical techniques based on importance sampling can be applied, since no sign problem is present. In the last decade, a first understanding of the QCD phase diagram at purely imaginary chemical potential has been developed, but most of it is so far based on investigations on coarse lattices (Nτ = 4, a = 0.3fm). Considering the N f = 2 case, at the Roberge-Weiss critical value of the imaginary chemical potential, the chiral/deconfinement transition is first order for light/heavy quark masses and second order for intermediate values of the mass: there are then two tricritical masses, whose position strongly depends on the lattice spacing and on the discretization. On Nτ = 4, we have the chiral mtric. π = 400MeV with unimproved staggered fermions and mtric. π & 900MeV with unimproved pure Wilson fermions. Employing finite size scaling we investigate the change of this tricritical point between Nτ = 4 and Nτ = 6 as well as between Wilson and staggered discretizations.
HYDROMETEOROLOGICAL REGIME OF THE WHITE SEA BASED ON SATELLITE ALTIMETRY DATA

The White Sea are the seas of the Arctic Ocean. Today complicated hydrodynamic, tidal, ice, and meteorological regimes of these seas may be investigated on the basis of remote sensing data, specifically of satellite altimetry data. Results of calibration and validation of satellite altimetry measurements (sea surface height and sea surface wind speed) and comparison with regional tidal model show that this type of data may be successfully used in scientific research and in monitoring of the environment. Complex analysis of the tidal regime of the White Sea and comparison between global and regional tidal models show advantages of regional tidal model for use in tidal correction of satellite altimetry data. Examples of using the sea level data in studying long-term variability of the Barents and White Seas are presented. Interannual variability of sea ice edge position is estimated on the basis of altimetry data.
Positional normalization as a first step in processing magnetic resonance brain images: work in progress

Retrospective automatic analysis of MR head images acquired in multicentre studies is often hampered by large differences in the positioning of the head within the image grid. To address this problem, we developed posnorm, a tool for preprocessing that normalizes the head position, utilizing only information contained within the image itself. Visual analysis of 21 test images from varied sources acquired with diverse protocols indicates that the procedure yields accurate and robust results. We envisage using posnorm routinely pending resolution of minor problems.
Hydroxyapatite – Graphene Composites as Advanced Bioceramics for Orthopedic Applications

The main focus of this book chapter is to provide the reader an overview of the synthetic process, physical and biological properties of hydroxyapatite (HA)– graphene nanocomposites in a rapidly expanding new field of advanced bio ceramics for orthopedic applications. Bioceramics are an important class of ceramics with different biocompatibility, from ceramic oxides to the other extreme bioresorbable materials. Among them, HA (Ca10(PO4)6(OH)2) as a major component of natural bone tissue has attracted a significant amount of attention in orthopedic applications due to its excellent biocompatibility, bioactivity and osteoconductivity. Morphological modifications to produce nanostructured HA such as nanorods and nanotubes are reported to possess improved mechanical and bio logical properties. Besides this, the substitution of various anions and cations can improve the crystal structure, crystallinity, surface charge and solubility, leading to major modifications in mechanical and biological responses upon implantation. On the other hand, the incorporation of reinforced fillers such as various carbon nanostructures may improve the bulk physical and chemical properties of the HA. First, the physicochemical features of HA are described and discussed, and then a general summary on the HA–graphene nanocomposites are given. Special attention is focused on these nanocomposites as advanced bioceramics for various biomedical applications. Finally, the conclusions are drawn, and the future outlooks are debated.
THE CALCULATION OF BORON AND CARBON SOLUBILITY FOR ( FeMe ) 2 BC ALLOY WITH LATTICE IN MODIFIED YUM-ROZERI MODEL

In present work the calculation of boron and carbon solubility in alloys (FeMe)2BC (Me = Fe, Cr, Mn, Al and others) has been performed. The modified Yum-Rozeri model of crystal has been applied. It has been used the configurational method in calculations taking into consideration all kinds of configurations of Fe, Me atoms around B, C atoms. Authors have received formulae determining the boron and carbon solubility in alloy in dependence on temperature, concentrations of Fe, Me components and energetic constants and also defining the mutual influence of boron and carbon solubility in alloy. The obtained formulae admits the presence of extremum at the temperature dependence of solubility. It has been found that boron and carbon are favourable for the dissolution each other in alloy at their atoms interaction of attraction type, and vice versa, these impurities inhibit the dissolution each other in the case of repulsion forces between their atoms. The obtained dependences are in agreement with experimental data according to which the boron presence in alloy decrease the carbon solubility.
Determinants of Brazilian Exports by Levels of Technological Intensity: A Gravity Model Analysis Using the PPML Estimator

The objective of this study is to analyze the determinants of Brazilian exports by levels of technological intensity in the period 2000-2015. Gravity models were estimated for total of the exports and for each type of exports by levels of technological intensity, using the PPML-estimator. The study indicates that there is a process of concentration of Brazilian exports in low technology and medium-low technology products, at the same period in which China's share of total Brazilian shipments abroad grew. Estimates of empirical gravity models have shown that the income and size of the consumer market of Brazil’s trading partners seem to have the greatest positive influence on the Brazilian exports. Indications of this study are that the Brazil should continue to diversify its trading partners to minimize the impacts of a possible reduction of the economic growth of large trading partners (such as China and the US) on its exports and increase its exports of products with greater technological intensity. The results also highlight the need for Brazil to make greater efforts to increase its competitiveness in the international market to reduce the negative impacts of transport costs on the final prices of products exported by the country.
STUDIES AND VALIDATION OF SOLUTIONS TO THE FORWARD PROBLEM OF FLUORESCENCE DIFFUSE OPTICAL TOMOGRAPHY

Diffuse Optical Tomography (DOT) and its variants such as Fluorescence DOT (FDOT) are powerful methods for non-invasive early cancer detection. The solution of this nonlinear inverse problem typically requires an accurate solution of the optical propagation model for the measured excitance on the boundary given the spatial distribution of the medium’s optical parameters (i.e., the solution of the forward problem). This necessitates a thorough validation of the solution schemes for the forward problem including comparison with experimentally measured quantities for a medium of interest. In the present work, a comparative study of forward model solutions using Monte Carlo, analytical and FEM based schemes has been done with the experimental excitance values obtained from phantoms for known optical parameters. We have also implemented the calculation of Jacobian matrices which is necessary for the inverse optimization schemes using the method of adjoints. FEM and Monte Carlo solutions have also been set up for fluorescence DOT problem. Numerical codes have been developed for the FEM solutions, while the standard Monte Carlo routine, MCML has been modified for fluorescence Monte Carlo procedures.
Design of improved DH ( Diffie-Hellman ) key agreement protocol based on distance bounding for peer-to-peer wireless networks

We propose the improved DH key agreement protocol over a radio link in peer-to-peer networks. The proposed protocol ensures the secure establishment of a shared key between two parties through DB (distance bounding). In this way, we can ensure the integrity of exchanged data under the limited power and limited capacity of memory. We analyze the inefficiency and problems of existing DH key agreement protocols. Based on the analysis we improve the DH key agreement protocol. Proposed protocol reduces the two messages exchanged, the four memory required, and (7682(k/64)-64)*2 operations, where k means the length of random sequence.
TRACE / HEAVY METAL ACCUMULATION IN SOIL AND IN THE SHOOTS OF ACACIA TREE

* Corresponding author : vural@gumushane.edu. tr ABSTRACT In this study, heavy metal/trace element accumulation was investigated in soils along the road passing through Gümüshane city center and shoots of 1-2 years of acacia trees (Robinia pseudoacacia L.) grown in these soils. Heavy metal contents in soils and plants were analyzed by Enrichment Factor (EF), Geo-accumulation index (Igeo) parameters, and by Bio Accumulation Factor (BAF), respectively. According to geo-accumulation index (Igeo) data, it is seen that the soil was unpolluted in terms of Cr, Co, Cu, Rb, Sr; unpolluted to moderately polluted in terms of V, Ni and Zn; moderate to excessively polluted in terms of As, and moderate to excessively polluted in terms of Pb. According to EF parameters, on the other hand, it is observed that the soil was non to slightly enriched in terms of Cr, Co, Sr and Ba; non to moderately enriched in terms of Ni and Cu; slightly to significantly enriched in terms of Zn; significant to very highly enriched in terms of As and slightly to over excessively enriched in terms of Pb. Although trace/heavy metal contents of acacia shoots were usually within normal values for acacia, it was determined that Cu, Fe, Mo, Ni, Sr and Zn concentrations were within and/or above upper limits of normal values in certain sampling points.

N A ] 2 6 A pr 2 01 9 A discrete least squares collocation method for two-dimensional nonlinear time-dependent partial differential equations

In this paper, we develop regularized discrete least squares collocation and finite volume methods for solving two-dimensional nonlinear time-dependent partial differential equations on irregular domains. The solution is approximated using tensor product cubic spline basis functions defined on a background rectangular (interpolation) mesh, which leads to high spatial accuracy and straightforward implementation, and establishes a solid base for extending the computational framework to three-dimensional problems. A semi-implicit time-stepping method is employed to transform the nonlinear partial differential equation into a linear boundary value problem. A key finding of our study is that the newly proposed mesh-free finite volume method based on circular control volumes reduces to the collocation method as the radius limits to zero. Both methods produce a large constrained least-squares problem that must be solved at each time step in the advancement of the solution. We have found that regularization yields a relatively well-conditioned system that can be solved accurately using QR factorization. An extensive numerical investigation is performed to illustrate the effectiveness of the present methods, including the application of the new method to a coupled system of time-fractional partial differential equations having different fractional indices in different (irregularly shaped) regions of the solution domain.
A Double Modal Parameter Tracking Method To Characteristic Modes Analysis

─ Mode tracking plays an important role in characteristic modes analysis. However, mode tracking in a proper and efficient way is still a challenging work. Based on modal linear correlation and modal stability, a double modal parameter tracking method is proposed in this paper, which is to track modes by correlating eigenvector and calculating the stability of characteristic angle simultaneously. To eliminate ambiguity case of multi-mode mapping one mode, two sorted mode with max Pearson correlation coefficient are identified same mode by utilizing saving best function. In order to verify accuracy and efficiency of the proposed method, four representative structures are analyzed. It can be observed that the proposed tracking method works better than the traditional methods. Index Terms ─ Characteristic modes analysis, double modal parameter tracking method, modal linear correlation, modal stability.
