For every integer $k\geq 2$ and every $A\subseteq \mathbb{N}$, we define the $k$-directions sets of $A$ as $D^{k}(A):=\{\boldsymbol{a}/\Vert \boldsymbol{a}\Vert :\boldsymbol{a}\in A^{k}\}$ and $D^{\text{}\underline{k}}(A):=\{\boldsymbol{a}/\Vert \boldsymbol{a}\Vert :\boldsymbol{a}\in A^{\text{}\underline{k}}\}$, where $\Vert \cdot \Vert$ is the Euclidean norm and $A^{\text{}\underline{k}}:=\{\boldsymbol{a}\in A^{k}:a_{i}\neq a_{j}\text{ for all }i\neq j\}$.

Abstract:

Abstract Increased intrarenal vascular resistance is suggested to accompany chronic kidney diseases (CKD), which is known to be closely associated with hypertension. However, there are few studies that have examined the relationship between blood pressure and intrarenal vascular resistance. Renal color Doppler ultrasonography is one method that can non-invasively evaluate intrarenal vascular resistance. In this study, we comprehensively studied the correlations between ultrasonic parameters and blood pressure indices to elucidate their relationships. In total, 162 patients with suspected CKD w

Results showed decrease of S/D ratio and PI for UA, UtA from 8 to 40 weeks of gestation and PI for RA from 20 to 40 weeks of gestation. S/D ratio and PI for A was not changed during second half of normal pregnancy. S/D ratio and PI for MCA were increased from 20 to 30 weeks of gestation and after that had tendency of decreasing to term.

The ratio 2Δ g / T c . where Δ g is the gap edge, T c is the critical temperature, is calculated in the framework of the model of strong electron-phonon coupling. Both isotropic and anisotropic pairing cases are considered. It is shown that the isotropic Eliashberg model can not account for the large values of the ratio 2Δ g / T c for the reasonable values of the electron-phonon coupling parameter λ, while anisotropic pairing can resolve this problem.

Using the expression, we analyze the AMR ratios of Ni and a half-metallic ferromagnet. These results correspond well to the respective experimental results.

The properties of false-twist textured yarns in the aspects of crimp characteristic and tensile behavior depend mainly on the draw ratio and the D/Y ratio.

While there was no noticeable change on the percent crystallinity by altering these parameters, tenacity increased and crimp contraction decreased with increasing draw ratio, and crimp stability decreased when the D/Y ratio increased. K/S value also decreased with increasing draw ratio.

Abstract:

Failure behaviour of aircraft sandwich panels under bending load has been investigated in this study. Three-points bending test was performed to the specimens with various span-to-thickness (S/d) ratios 32, 40, and 60. Testing method and dimension of specimens were adhering to the American Society for Testing and Materials (ASTM) D-790M. Deflection and energy absorption of the sandwich panels was characterized by specific span-to-thickness (S/d) ratios. It was found that specimen with S/d of 40 has the steepest slope in stress-strain curve and specimen with S/d of 32 has the highest flexure st

Abstract:

To reduce emissions, CNG engines are commonly equipped with three-way catalytic converters. However when the engines run at transient conditions, the air fuel ratio can not be precisely controlled at theoretical value by traditional means, so the catalytic converters can not achieve their desired effect. This paper presents a new method for CNG engines to control air fuel ratio at transient conditions. The moments which intake and exhaust valves open are used as the trigger signals for ECU to collect the test data simultaneously. The dynamic information of CNG engine is detected by multiple se

Abstract:

Abstract The ratio of snowfall to total precipitation (S/P ratio) is an important metric that is widely used to detect and monitor hydrologic responses to climate change over mountainous areas. Changes in the S/P ratio over time have proved to be reliable indicators of climatic warming. In this study, the seasonality and interannual variability of monthly S/P ratios over High Mountain Asia (HMA) have been examined during the period 1950–2014 based on a three-member ensemble of simulations using the latest GFDL AM4 model. The results show a significant decreasing trend in S/P ratios during the

Abstract:

Coconut shortage has been a concerning issue in Indonesia for the past few years. Using a system dynamics (SD) approach and the supply and demand ratio (S/D ratio), this study aims to build a simulation model for the sustainability of coconut supply in Indonesia. The result shows that the S/D ratio will fall below 1 by 2023, indicating that the supply will no longer meet the demands. The model suggests that the most effective policy is doubling the coconut plantations areas and increasing the yield up to 2 tons/ha of copra.

Doppler profiles of H and D atoms from the reaction S(1D) with HD and a 1:1 mixture of H2 and D2 have been measured by a laser-induced fluorescence technique with a vacuum ultraviolet laser. An isotopic channel branching ratio of φ (SD + H)/φ (SH + D) is measured to be 0.9 ± 0.1 in the reaction of S(1D) + HD at average collision energy Ecoll = 1.2 kcal/mol. In S(1D) + HD, D2, and H2, the translational energies released are almost the same, 4.6 ± 0.5 kcal/mol for H and D production channels.

And then, the D-S evidence theory-based information fusion technique is employed to integrate these two results and make a final decision. To compare the damage identification

The results show that m value is determined by the two parameters: interval number among piles (n) and pile diameter-spacing ratio (d/s). m value greatly decreases with the increase of d/s at the constant n, whereas m slightly decreases with the increase of n at the c

The objective functions are normalized by a function of the desired regions, which avoids a bias to produce an overly large or small region resulting from data noise. The normalization functions that we employ are us

In order to reduce the production cost of preparing C-S-H seeds (C-seeds) by wet grinding cement, this paper prepares a composite C-seed by mixing cement and silica fume (SF) in six proportions. Adding the C-seed to high-volume fly ash (FA) concrete would improve the insufficient early strength of this type of concrete. The properties of different C-seeds, as well as their effects on the mechanical properties, hydration characteristics and microstructure of concrete, were assayed by XRD, SEM and TG. As the results show, silica fume can contribute to the formation of the C-seed by promoting the

Interpolation formulas for the apodized magnitude-mode fast Fourier transformed (FFT) spectra determine accurately the frequency, damping constant, and amplitude of time-domain damped signals. However, additive noise causes a large amount of error in interpolation. In this paper, we obtain, theoretically, the frequency-domain signal-to-noise (S/N) ratio due to windowing by the function of sinα( X) and quantization with finite bit-length analog-to-digital (A/D) converters. Then, with the use of the squared ratios between three magnitudes nearest to the peak maximum on the apodized FFT spectrum,
