Unsupervised Keyword Extraction from Polish Legal Texts

In this work, we present an application of the recently proposed unsupervised keyword extraction algorithm RAKE to a corpus of Polish legal texts from the field of public procurement. RAKE is essentially a language and domain independent method. Its only language-specific input is a stoplist containing a set of non-content words. The performance of the method heavily depends on the choice of such a stoplist, which should be domain adopted. Therefore, we complement RAKE algorithm with an automatic approach to selecting non-content words, which is based on the statistical properties of term distribution

An Alternate Method for Fourier Transform Infrared (FTIR) Spectroscopic Determination of Soil Nitrate Using Derivative Analysis and Sample Treatments

This study aimed at examining effective sample treatments and spectral processing for an alternate method of soil nitrate determination using the attenuated total reflectance (ATR) of Fourier transform infrared (FTIR) spectroscopy. Prior to FTIR measurements, soil samples were prepared as paste to enhance adhesion between the ATR crystal and sample. The similar nitrate peak heights of soil pastes and their supernatants indicated that the nitrate in the liquid portion of the soil paste mainly responded to the FTIR signal. Using a 0.01-M CaSO4 solution for the soil paste, which has no interference bands in the characteristic spectra of the analyte, increased the concentration of the nitrates to be measured. Second-order derivatives were used in the prediction model to minimize the interference effects and enhance the performance. The second-order derivative spectra contained a unique nitrate peak in a range of 1,400-1,200 cm(-1) without interference of carbonate. A partial least square regression model using second-order derivative spectra performed well (R (2) = 0.995, root mean square error (RMSE) = 23.5, ratio of prediction to deviation (RPD) = 13.8) on laboratory samples. Prediction results were also good for a test set of agricultural field soils with a CaCO3 concentration of 6% to 8% (R (2) = 0.97, RMSE = 18.6, RPD = 3.5). Application of the prediction model based on soil paste samples to nitrate stock solution resulted in an increased RMSE (62.3); however, validation measures were still satisfactory (R (2) = 0.99, RPD = 3.0

Role of dietary concentrates on the venison quality of Sika deer (Cervus nippon)

The aim of this study was to evaluate the effect of feed concentrate level on carcass characteristics and meat quality of sika deer (Cervus nippon). A total of 16 sika deer (mean bodyweight 30 kg) were randomly assigned to one of two treatments, namely Treatment 1 (T1): fed concentrate at 1.5% of total bodyweight); and Treatment 2 (T2): fed concentrate ad libitum. Both groups had free access to roughage (hay) and water. Each group was fed concentrate twice daily (at 09h00 and 16h00) for eight months. The fat concentration of venison from deer in T2 was significantly greater than that of T1. However, fat loss through cooking, shear force, and pH did not differ significantly between the two groups. Water-binding capacity of venison from deer in T1 was significantly greater (2.83%) than that of T2. Colour parameters a* (redness) and b* (yellowness) were significantly greater for venison from T2 than for deer in T1. Likewise, cholesterol concentration of venison from deer in T2 was significantly greater than for deer in T1. However, the cholesterol concentration in venison from deer that were subjected to both treatments was less than that of meat from other livestock species. In conclusion, the results of this study provide a baseline to estimate fodder cost standards to produce sika deer venison, and would aid commercial deer farmers in developing optimal management strategies for venison production.Keywords: carcass composition, concentrate feeding, meat qualit

Longitudinal emittance oscillation in a superconducting drift tube linac

In drift tube linacs a beam energy spread results form the finite beam size. Radial variation of the axial accelerating field induces a beam energy spread, which, in general, will accumulate as the beam passes through successive drift tubes. This paper shows that under some conditions of periodic transverse focusing and longitudinal phase focusing, the correlation between the longitudinal and transverse motion can be used to correct the energy spread. The process of achieving such a correction is first described in a simplified situation, and then demonstrated for a particular tuning using a ray-tracing program which models a low velocity and low charge state linac designed for radioactive ion beams

Thermo-hydraulic performance comparison of steady laminar flow channels

Thermo-hydraulic numerical analysis has been carried out to compare the characteristics of various shaped channels with two kinds of coolants such as EGW (EthyleneGlycol/Water) and PAO (PolyalphaOlefin). In this study, single-phase, constant property and threedimensional laminar forced convections are considered, and the governing differential equations for continuity, momentum, and energy transfer are solved computationally using the finitevolume method and the commercial codes of ICEPAK and FLUENT. The variations of the maximum temperatures as well as the temperature difference on the heat source surface with pumping power are compared depending on the coolants and channels.Papers presented to the 12th International Conference on Heat Transfer, Fluid Mechanics and Thermodynamics, Costa de Sol, Spain on 11-13 July 2016

Gauge coupling renormalization in orbifold field theories

We investigate the gauge coupling renormalization in orbifold field theories preserving 4-dimensional N=1 supersymmetry in the framework of 4-dimensional effective supergravity. As a concrete example, we consider the 5-dimensional Super-Yang-Mills theory on a slice of AdS_5. In our approach, one-loop gauge couplings can be determined by the loop-induced axion couplings and the tree level properties of 4-dimensional effective supergravity which are much easier to be computed.Comment: 18 pages, JHEP style; 1-loop corrections to gauge kinetic functions are fully computed, references are adde

A high gradient superconducting quadrupole for a low charge state ion linac

A superconducting quadrupole magnet has been designed for use as the focusing element in a low charge state linac proposed at Argonne. The expected field gradient is 350 T/m at an operating current of 53 A, and the bore diameter is 3 cm. The use of rare earth material holmium for pole tips provides about 10% more gradient then iron pole tips. The design and the status of construction of a prototype singlet magnet is described

Supersymmetry Breaking and Moduli Stabilization with Anomalous U(1) Gauge Symmetry

We examine the effects of anomalous U(1)_A gauge symmetry on soft supersymmetry breaking terms while incorporating the stabilization of the modulus-axion multiplet responsible for the Green-Schwarz (GS) anomaly cancellation mechanism. In case of the KKLT stabilization of the GS modulus, soft terms are determined by the GS modulus mediation, the anomaly mediation and the U(1)_A mediation which are generically comparable to each other, thereby yielding the mirage mediation pattern of superparticle masses at low energy scale. Independently of the mechanism of moduli stabilization and supersymmetry breaking, the U(1)_A D-term potential can not be an uplifting potential for de Sitter vacuum when the gravitino mass is smaller than the Planck scale by many orders of magnitude. We also discuss some features of the supersymmetry breaking by red-shifted anti-brane which is a key element of the KKLT moduli stabilization.Comment: 32 pages; references are adde
