TL;DR: In this article, diamond-like carbon thin films were prepared by pulsed-laser evaporation by using a diamond target irradiated by a XeCl laser with a power density of 3×108 W/cm2 and carbon atoms, together with a small number of ions, were produced.
Abstract: Diamond-like carbon thin films were prepared by pulsed-laser evaporation In this method a carbon target was irradiated by a XeCl laser with a power density of 3×108 W/cm2 and carbon atoms, together with a small number of ions, were produced Deposition rates and film properties changed sensitively with substrate temperature The films deposited at 50°C were diamond-like, having reasonable hardness, high refractive index (21–22 at 633 nm), optical transparency in the infrared, electrical resistivity of 108 Ω cm and chemical inertness (no dissolution in a HF∶HNO3 solution) The band gap measured from optical absorption was 14 eV Raman spectrum and infrared absorption, whose features varied with the substrate temperature, were also measured The films were amorphous and no crystallinity was observed, as confirmed by x-ray diffraction, transmission electron diffraction and Raman spectroscopy Hydrogen atoms were incorporated in the films with a typical H/C ratio of 03 The application of a negative bias to the substrate modified the deposition due to the presence of ions

TL;DR: In this paper, an ECU of a driving support device predicts the risk of contact between a host vehicle and obstacles around the host vehicle when the vehicle travels by a driving action related to at least one normative action candidate.
Abstract: An ECU of a driving support device predicts the risk of contact between a host vehicle and obstacles around the host vehicle when the host vehicle travels by a driving action related to at least one normative action candidate, which is a normative driving action candidate of the host vehicle for the surrounding conditions of the host vehicle. Therefore, it is possible to provide the normative action candidates considering the risk of contact between the host vehicle and the obstacles around the host vehicle.

TL;DR: A novel reduced-complexity near-optimal detection algorithm is proposed for enhancing the recent Coherently-detected Space-Time Shift Keying (CSTSK) scheme employing arbitrary constellations, and it is revealed that the proposed detector is capable of approaching the optimal Maximum Likelihood (ML) detector's performance, while avoiding the exhaustive ML search.
Abstract: A novel reduced-complexity near-optimal detection algorithm is proposed for enhancing the recent Coherently-detected Space-Time Shift Keying (CSTSK) scheme employing arbitrary constellations, such as {\cal L}-point Phase-Shift Keying (PSK) and Quadrature Amplitude Modulation (QAM). The proposed detector relies on a modified Matched Filter (MF) concept. More specifically, we exploit both the constellation diagram of the modulation scheme employed as well as the Inter-Element-Interference (IEI)-free STSK architecture. Furthermore, we generalize the Pulse Amplitude Modulation (PAM)- or PSK-aided Differentially-encoded STSK (DSTSK) concept and conceive its more bandwidth-efficient QAM-aided counterpart. Then, the proposed reduced-complexity CSTSK detector is applied to the QAM-aided DSTSK scheme, which enables us to carry out low-complexity non-coherent detection, while dispensing with channel estimation. It is revealed that the proposed detector is capable of approaching the optimal Maximum Likelihood (ML) detector's performance, while avoiding the exhaustive ML search. Interestingly, our simulation results also demonstrate that the reduced-complexity detector advocated may achieve the same performance as that of the optimal ML detector for the specific STSK scheme's parameters. Another novelty of this paper is that the star-QAM STSK scheme tends to outperform its square-QAM counterpart, especially for high number of dispersion matrices. Furthermore, we provided both the theoretical analysis and the simulations, in order to support this unexpected fact.

TL;DR: A remarkable increase in isolates with decreased susceptibility to penicillin, tetracycline, oral cephalosporins, and fluoroquinolones was observed from 2001 through 2002.
Abstract: Four hundred sixty-two clinical isolates of Neisseria gonorrhoeae recovered from 1999 through 2002 in central Japan were examined for MICs of antimicrobial agents. The majority was sensitive to ceftriaxone and spectinomycin, but a remarkable increase in isolates with decreased susceptibility to penicillin, tetracycline, oral cephalosporins, and fluoroquinolones was observed from 2001 through 2002.
