    Notes:
    In an experimental investigation of the response of a chaotic system to a chaotic driving force, we have observed synchronization of chaos of the response system in the forms of generalized synchronization, phase synchronization, and lag synchronization to the driving signal. In this paper we compare the features of these forms of synchronized chaos and study their relations and physical origins. We found that different forms of chaotic synchronization could be interpreted as different stages of nonlinear interaction between the coupled chaotic systems. © 1998 American Institute of Physics.

    Notes:
    Three methods are given for imposing random telegraph phase or frequency noise on a stabilized cw laser thus giving explicit control of the coherence of the laser field. In the case of phase noise, the resulting laser spectrum consists of a carrier part with nearly Lorentzian shaped noise sidebands which have full-width at half maximum up to 14 MHz. Complete suppression of the carrier is possible if the phase is made to jump by π radians. Frequency telegraph noise results in a laser power spectrum that can be single or double peaked, depending on the relative sizes of the average dwell time and the frequency jump. The laser field has been produced for studies of noise in nonlinear spectroscopic interactions. Measurements of the resulting laser spectra are presented. As an example of the application of such a noisy laser, some results from studies of the dependence of two photon absorption on higher-order optical coherences are given.

    Notes:
    Abnormalities of in-vitro sperm-mucus penetration, ovarian hormone deficiency, specifically poor progesterone surge, and luteal cyst formation were assessed prospectively in 95 couples with fully investigated primary infertility of 3·3 years duration. Abnormal spermmucus penetration was found in 22, half of whom could have been identified on semen assessment alone. Ten other males had recurrent oligospernia but with normal motility and mucus penetration. Twentyone patients had a poor progesterone surge and seven of them demonstrated retained luteal phase cysts. Endocrine and mucus penetration abnormalities did not coincide, demonstrating that they are distinct and unrelated phenomena. A significant number of couples were found for whom the term‘unexplained infertility’was no longer applicable and appropriate management could be considered.

    Notes:
    Summary. Eight oligomenorrhoeic patients with increased luteinizing hormone (LH) and androgen levels who had failed to conceive during prolonged anti-oestrogen therapy received a new treatment. Large doses of an LH-releasing hormone (LHRH) analogue (HOE 766) were used to suppress circulating gonadotrophin concentrations and block the positive feedback gonadotrophin surge. Ovulation was induced during continued LHRH analogue treatment with exogenous gonadotrophins without interference from the patient's own pituitary. Seven of eight patients conceived rapidly without premature luteinization and without excessive ovarian enlargement. These complications had occurred in control treatment cycles using exogenous gonadotrophins in the absence of the LHRH analogue.

    Notes:
    We present the fabrication and characterization of nonintentionally doped GaN and GaN:Mg Schottky metal–semiconductor–metal (MSM) photodetectors, grown on sapphire by metalorganic chemical vapor deposition. Low-leakage, Schottky contacts were made with Pt/Au. The devices are visible blind, with an ultraviolet/green contrast of about five orders of magnitude. The response times of the MSM devices were 〈10 ns and about 200 ns for GaN and GaN:Mg, respectively. The noise power spectral density remains below the background level of the system (10−24 A2/Hz) up to 5 V, for the undoped GaN MSM detector. © 1999 American Institute of Physics.

    Notes:
    We report the fabrication and characterization of AlxGa1−xN p-i-n photodiodes (0≤x≤0.15) grown on sapphire by low-pressure metalorganic chemical vapor deposition. The devices present a visible rejection of six orders of magnitude with a cutoff wavelength that shifts from 365 to 338 nm. Photocurrent decays are exponential for high load resistances, with a time constant that corresponds to the RC product of the system. For low load resistances, the transient response becomes non-exponential, with a decay time longer than the RC constant. This behavior is justified by the strong frequency dependence of the device capacitance. By an admittance analysis, we conclude that speed is not limited by deep levels, but by substitutional Mg capture and emission time. © 1999 American Institute of Physics.

    Notes:
    We present the growth and characterization of GaN p-i-n photodiodes with a very high degree of visible blindness. The thin films were grown by low-pressure metalorganic chemical vapor deposition. The room-temperature spectral response shows a high responsivity of 0.15 A/W up until 365 nm, above which the response decreases by six orders of magnitude. Current/voltage measurements supply us with a zero bias resistance of 1011 Ω. Lastly, the temporal response shows a rise and fall time of 2.5 μs measured at zero bias. This response time is limited by the measurement circuit. © 1998 American Institute of Physics.

    Notes:
    To compare the efficacy and acceptability of conventional intravenous sedation with patient-controlled inhalational isodesox, 57 women undergoing outpatient oocyte recovery were randomly allocated to receive isodesox by face mask, while 55 women were given intravenous fentanyl and midazolam. Women's satisfaction with pain relief, peroperative pain, clouding of memory and the surgeons' assessment of operating conditions were evaluated. Thirty-eight women in the inhalation group (67%) and 41 (75%) women in the intravenous group were ‘very satisfied’ with their analgesia (p = 0.41). The mean (SD) pain score in women given isodesox was 46.8 (34.7), while in the intravenous group it was 34.1 (21.3) (p = 0.02). Oxygen saturation levels 〈 94% were recorded in one woman using isodesox and in 16 (29%) women given intravenous analgesia. Despite higher pain scores, in comparison with the conventional analgesia, patient-controlled isodesox offers a safer method of pain relief with comparable satisfaction rates.
